SUMMARY OF THE INVENTION

The inventive method for mounting a rocking laser device is based on a rocking laser device, wherein the rocking laser device has at least a housing, a rocking device arranged in a rocking manner in the housing, and a rocking device with the aid of an adjustment receptacle. A laser unit for generating a laser beam arranged on or in the rocking device. According to the invention, the laser unit is aligned with elastic clamping means on or in the adjustment receptacle with reference to a preferred direction, in particular with reference to a vertical line, and is then fixed by means of adhesive.

Oscillating laser devices are used to generate optical markings, in particular laser markings, for alignment, calibration, measurement and/or marking tasks, such as occur in particular in the manual field, for example in the interior expansion of buildings appears during installation work, when setting marks on walls, etc. In principle, the oscillating laser device allows the production of laser markings, in particular the projection of laser markings onto objects that are a reference independent of the orientation of the floor, ceiling or other objects such as vertical walls of cabinets, but in particular also independently Reference to the orientation of the swing laser device housing.

In principle, the oscillating laser device allows, in at least one operating state, the generation of laser markings aligned by means of a gravitational field, ie aligned by means of the direction of gravity or aligned with a reference vertical, as a reference. The generated laser markings can in particular be oriented horizontally and/or vertically with respect to the oscillating laser device, for example, and/or at another predetermined angle to the vertical.

For this purpose, the rocking laser device has a housing with at least one opening, in particular a window, wherein at least one rocking device is arranged in the housing. The rocking device is provided for holding and aligning at least one laser unit to be mounted on or in the rocking device by means of the adjustment receptacle, wherein the laser unit is designed to be substantially independent of the orientation of the housing by means of the rocking device by means of a vertical The wire is free to self-calibrate, especially to rock or wiggle across the board. The laser unit is used for generating a laser beam, in particular for generating at least one laser marking on the object.

The rocking device has a suspension provided on the housing, or on a part connected to the housing, which allows vertical alignment of the rocking device in a gravitational field and substantially independent of the orientation of the housing. The suspension can be realized, for example, in particular by means of a cardan-type bearing arrangement. "Substantially independent of the orientation of the housing" means that there is sometimes an angular range for the orientation of the housing, to which the function of the rocking device, in particular its precise alignment by means of the vertical line, is limited. This angular range with respect to the vertical includes in particular 5° to 15°, usually 5° or 8°. In order to shorten the oscillation duration of the rocking device that is rocking and that is suspended as frictionlessly as possible within the scope of the technical possibilities, without reducing the accuracy of the adjustment of the final position of the rocking device in the gravitational field, the rocking device can have a Eddy current damping mechanism using the Waltenhofen pendulum principle. Advantageously, the swivel device of the oscillating laser device—and thus also the adjustment receptacle together with the laser unit—can be made with high precision within a short time after the oscillating laser device has been erected or after a collision with the oscillating laser device. Degrees are automatically calibrated in the Earth's gravitational field.

The adjustment receiver is used for accommodating at least one laser unit. Advantageously, the adjustment receptacle can be arranged beside, in or on the rocking device, in particular in a cohesive, force-fit and/or form-fit manner. The device can be realized in a releasable or non-releasable manner, in particular in a non-destructive manner. In particular, the adjustment receptacle can also be designed in one piece with the rocking device. "In one piece" means that the adjustment receptacle is designed, due to the manufacturing method, in particular, for example by injection molding, or by gluing, slotting, hooking, etc., in such a way that it is form-fit and material-fit in a non-destructive manner. The rocking device is released. The adjustment receptacle is preferably used for aligning the laser unit with reference to a preferred direction, in particular with reference to a vertical line, and for its indirect attachment to the rocking device. It should be noted that the alignment of the laser unit with respect to the preferred direction also implies the alignment of the laser unit with respect to the rocking device. According to the invention, the laser unit is aligned on or in the adjustment receptacle by means of at least one elastic clamping device, with reference to a preferential direction, in particular with reference to the vertical line, and then fixed by means of adhesive.

The laser unit has at least one light source, such as a laser, a semiconductor laser or a laser diode, for producing a laser marking on the object. The laser unit can likewise have optics, in particular, for example, lenses, filters, diffractive elements, mirrors, reflectors, optically transparent glass slides etc. In particular, cylindrical lenses can be used in order to achieve a technically simple realization of the laser beam emitted by the light source to diverge into a laser surface, so that a line, in particular a marking line, is generated when the laser surface is projected onto the object. Furthermore, the laser unit may also have non-optical components, such as mechanisms for adjustment, and/or electronic circuits for controlling the light source and/or for controlling other components of the laser unit. In particular, the laser unit can also have a motor for rotating the light source or the beam-steering optics, also suitable for generating laser markings diverging in a plane, such as in particular for so-called rotary lasers.

The design, in particular the shape and the color of the laser markings produced by means of the oscillating laser device, in particular the laser unit, can also vary depending on the field of use and purpose, but in particular include at least marking points and/or marking lines, but also Interrupted marker line. In addition, the laser unit may be arranged to design the laser marking to be changeable over time, in particular eg blinking. "Setup" especially refers specifically to "programming", "designing" and/or "configuring". An object is "configured" for a certain function, which means in particular that the object performs and/or performs said certain function or is designed to perform this function in at least one application state and/or operating state.

The rocking laser device can preferably also have several, in particular two or three, laser units, which are received by at least one adjustment receptacle, preferably in each case by an adjustment receptacle, and are thus mounted on the rocking device so that the When the rocking device is calibrated by means of the vertical line, there are simultaneously several laser units, and thus the laser markings they produce, that are calibrated with respect to the vertical line and can be used as a reference. The oscillating laser device can preferably have at least two laser units which emit mutually perpendicular laser surfaces, the projection of which on the object produces marking lines which are respectively perpendicular to each other. It is particularly preferred here that the vertically oriented laser surface is oriented in a direction defined by a vertical line, that is to say that the vertically oriented laser surface is aligned with the vector representing the force of gravity.

The rocker laser device also has a device which is provided for supplying the rocker laser device with electrical energy in order to be put into operation and during operation. The device is preferably a grid-independent energy accumulator, in particular a battery, battery, fuel cell, capacitor, other energy accumulators of interest to a person skilled in the art, or a combination/addition of these. For powering the swing laser device, rechargeable accumulators are particularly suitable, for example with nickel-metal hydride chemical cells, lithium chemical cells or lithium-ion chemical cells (Zellchemie). The device for supplying power preferably has a releasable form-fit and/or force-fit connection interface. “Releasable” in this context means in particular that it can be detached without damage, in particular by a user of the rocker laser device. Therefore, the device for supplying power can preferably be arranged on the measuring device in a removable and replaceable manner. Particularly preferably, the removable means for supplying power can be supplied with energy and charged again from the grid inside and/or outside the measuring device.

A switch, in particular arranged on the housing, or an alternative component with this function, is used to switch the oscillating laser device on and off. In addition, some other design can be specified which is of interest to a person skilled in the art, such as another switch for securing the rocking device in the housing, especially for transport purposes, or for stopping the rocking device ( Auspendeln) and then flipped the rocker laser device.

In the method of the invention, the laser unit is aligned on or in the adjustment receptacle with at least one elastic clamping device, with reference to a preferential direction, in particular with reference to a vertical line, and then fixed by means of adhesive.

A clamping device is in particular a device which is provided to mechanically hold, fix, clamp and/or clamp an object at least temporarily, in particular at least for the duration of the installation. In the following, “holding” is also referred to in particular as “applying a holding force”, which means that the clamping device is designed in the method of the invention to advantageously arrange, in particular fix, the laser unit during the method steps of setting and aligning On or in the adjustment receiver. The clamping device is advantageously provided for exerting a holding force on the laser unit and the adjustment receptacle, in particular during installation of the rocking laser device, ie in particular during mounting and alignment of the laser unit on or in the adjustment receptacle. According to the invention, a simple, reliable and rapid alignment of the laser unit on or in the adjustment receptacle in the proposed method can thus be achieved by means of the clamping device.

According to the invention, the clamping device is designed to be at least partially elastic, preferably completely elastic, so as to ensure that the clamping device can be deformed reversibly in the event of a force acting on the clamping device. Advantageously, the clamping device can thus also be used to apply the force if the shape of the clamping device undergoes a reversible change. Particularly advantageously, this force can be used to hold the laser unit on or in the adjustment receptacle by means of a self-locking force fit. "Self-locking" means in particular that the laser unit is held on or in the adjustment receptacle due to the force exerted by the clamping device, so that frictional resistance, in particular stiction resistance, is created between the adjustment receptacle and the laser unit, which friction The resistance inhibits displacement of the laser unit, in particular movement and/or rotation of the laser unit.

The term "utilization" means in particular that in the method of the invention, in addition to the clamping device, other auxiliary means can also be used, such as adjustment aids and/or adjustment devices, tools such as pliers, indenters, etc., as well as others known in the art Mechanisms, in particular fixing means, for aligning the laser unit on or in the adjustment receptacle appear meaningful to the skilled person.

In the method of the invention, the laser unit is aligned on or in the adjustment receptacle with reference to a preferential direction, in particular with reference to a vertical line, by means of a clamping device. The preferred direction may advantageously—but not exclusively—denote a vertical line specified by a pendulum rocking device, with respect to which the laser unit is to be calibrated. The laser unit is advantageously aligned so that the laser markings, in particular marking spots and/or marking lines, produced by the laser unit are oriented either in the direction of the vertical line or perpendicular to this direction. The calibration takes place in particular when the laser marking is acquired in the desired direction with reference to the preferred direction when the rocking device is swayed.

The method of calibrating a laser unit with reference to a preferred direction is not limited to the calibration of one laser unit, but can also be transferred to a plurality of other laser units that may be present in a swing laser arrangement.

After the method step of calibration, in a further method step of the method according to the invention, the laser unit is fixed, in particular permanently fixed, by means of an adhesive. "Fixed" means that the mutually aligned components, ie, the laser unit and the adjustment receptacle, are connected to one another in particular permanently, preferably in a cohesive and/or form-fit manner. Advantageously, the clamping device remains in its position during bonding. “Permanently” means in particular that the laser unit and the adjustment receptacle are non-releasably, in particular non-destructively, irreversibly and preferably irreversibly connected to one another. Advantageously by fixing, the alignment of the laser unit on or in the adjustment receptacle is made possible in the event of subsequent vibrations, jolts or shocks that occur, for example, during transport, during use or due to tipping over of the rocking laser device Keep.

The method for mounting the rocking laser device advantageously allows an efficient and simple alignment of the laser unit on or in the adjustment receptacle. Since the laser unit is already held by means of the clamping device in the position provided on or in the adjustment receptacle, for example in particular being pressed on or in the adjustment receptacle, a person skilled in the art who performs the installation can particularly advantageously concentrate on The main method steps for aligning the laser unit with reference to the preferred direction on or in the adjustment receptacle. By transposition of the laser unit on or in the adjustment receptacle, in particular by movement or rotation of the laser unit on or in the adjustment receptacle, a person skilled in the art can, with reference to the preferred direction, also change the laser with respect to the rocking device The direction of the unit can thus also change the direction of the laser beam emitted by the laser unit. When the desired orientation of the laser unit on or in the adjustment receptacle is achieved, the laser unit on or in the adjustment receptacle is then fixed in the final adjusted orientation by means of an adhesive.

Particularly advantageously and in contrast to the prior art, the method according to the invention dispenses with the use of means for permanent fixing, which also (possibly) influence the movement on or in the adjustment receptacle after the laser unit has been calibrated. the direction of the laser unit. This is the case in particular when using fixing means, which apply a force for fixing, as is the case with screws, for example. If the laser unit is subsequently fastened by means of screws after calibration, eg on or in the adjustment receptacle, the laser unit can easily and particularly disadvantageously be displaced on or in the adjustment receptacle due to the forces exerted when the screw is tightened. Especially moving or rotating. For this reason, the alignment of the laser unit with reference to the preferred direction is affected, so that additional steps are required during installation of the swing laser device, in particular the need to re-align the laser unit with reference to the preferred direction. The method of the present invention overcomes these disadvantages of the prior art, based on fixing by means of an adhesive.

In a preferred embodiment of the method according to the invention for mounting an oscillating laser device, the clamping device has at least one compression spring, in particular a clamping spring, in order to hold the laser unit in the adjustment receptacle during calibration .

Compression springs, in particular clamping springs, are preferred elastic clamping means and, due to the reversible, elastic shape change, are advantageously suitable for applying a force which can be used to cause the laser unit to self-lock, ie in particular by energy. The friction that causes the force is held on or in the adjustment receptacle in a non-positive manner. Furthermore, compression springs, in particular clamping springs, can be produced particularly economically.

In a preferred embodiment of the method according to the invention for mounting an oscillating laser device, the laser unit is pressed into the adjustment receptacle by means of a clamping device in a receptacle which passes through the adjustment receptacle at least partially axially. on the piece.

The state-of-the-art enabling the mounting of rocking laser devices can be achieved in a method step of aligning and fixing the laser unit on or in the adjustment receptacle by means of the receptacle passing through the adjustment receptacle at least partially axially Personnel align the laser unit particularly easily and efficiently when adjusting the receptacle. For example, the limitation of at least part of the movement clearance space of the laser unit during calibration of the laser unit on or in the adjustment receiver advantageously simplifies and accelerates the calibration of the laser unit with reference to the preferred direction. In this way, the receptacle passing through the adjustment receptacle at least partially axially, in particular when the receptacle forms a lateral limit and/or guide of the laser unit, for example, can preferably also be used for adjusting the A mechanism for positioning a laser unit on or in a holder.

With a suitable selection of the dimensions of the receptacle that passes through the adjustment receptacle at least partially axially, in particular in the case of small clearance spaces between the adjustment receptacle and the accommodated laser unit, it is advantageously possible to achieve The alignment of the laser unit on or in the adjustment receptacle is particularly mechanically stable and thus particularly durable. For example, when the laser unit is pressed against the adjustment receptacle, an advantageous force distribution can be achieved, in particular a force distribution on a large pressing surface, which leads to a difference between the laser unit and the adjustment receptacle The friction between the pieces is advantageously distributed over a large surface. Furthermore, external influences, such as in particular direct impacts on the laser unit, can be effectively avoided, since the receptacle, which passes through the adjustment receptacle at least partially axially, advantageously surrounds the laser unit protectively. Furthermore, in the method step of fixing according to the invention, a particularly firm fixing of the laser unit on or in the adjustment receptacle can be achieved by means of an adhesive.

Furthermore, the adjustment receptacle has a receptacle for accommodating the laser unit, which at least partially extends axially through the adjustment receptacle, which is a particularly simple and economical production of the adjustment receptacle. and particularly easily applicable or usable embodiments.

In a preferred embodiment of the method according to the invention for mounting a rocking laser device, the laser unit is pressed against the adjustment by at least one clamping spring in a receptacle which passes through the adjustment receptacle at least partially axially. on the receptacle, wherein at least one clamping spring is located at least partially between the adjustment receptacle and the laser unit.

At least one clamping spring is located at least partially between the adjustment receptacle and the laser unit and at least partially in the receptacle, the receptacle passing through the adjustment receptacle at least partially axially, with which clamping spring it can be advantageous A particularly space-saving clamping device is realized in the method step of aligning the laser unit on or in the adjustment receptacle. The volume of the rocking device with the laser unit arranged by means of the adjustment receptacle can thus also be reduced particularly advantageously. "At least partially between the adjustment receptacle and the laser unit" means that the clamping spring can in particular also protrude from an intermediate region between the adjustment receptacle and the laser unit, for example for easy placement and placement in this intermediate region. / or calibrate the clamping spring.

Different, in particular geometric shapes of the clamping spring and their arrangement between the laser unit and the adjustment receptacle are conceivable: the clamping spring can, for example, be suitably shaped so that it can be circumferentially at least partially axially arranged. The circumference of the receptacle passing through the adjustment receptacle is placed in the receptacle passing through the adjustment receptacle at least partially axially. This is achieved in particular by means of annular clamping springs, for example. Alternatively, a clamping spring is realized, which is accommodated in the receptacle at least partially axially penetrating the adjustment receptacle at a certain position through the adjustment receptacle. Furthermore, as an alternative, a plurality of clamping springs can also be realized, which are arranged at certain positions along the circumference of the receptacle which at least partially penetrates axially through the adjustment receptacle, for example all 120° of the 3 clamping springs. At least partially axially through the receptacle of the adjustment receptacle.

Preferably, the at least one clamping spring can be designed as a leaf spring, which can be arranged particularly advantageously between the adjustment receptacle and the laser unit due to its small thickness, even if the distance between the adjustment receptacle and the laser unit is small. in the middle area. The clamping spring, in particular the leaf spring, preferably consists of a material that is stable but elastically deformable under force, for example, spring steel.

In addition, means, in particular fixed means, for positioning the clamping device, in particular the clamping spring, on or in the adjustment receptacle can be provided particularly advantageously. These means can be, for example, guide strips and/or webs and/or stop pins and/or other means suitable for calibrating and/or fixing the clamping springs which appear to a person skilled in the art to be meaningful. These means advantageously allow the clamping device, in particular the at least one clamping spring, to be arranged on or in the adjustment receptacle in a particularly clamping manner, and to prevent it from arranging and/or aligning the laser unit to or at least partially on the axis Slips off when passing downwardly into the receptacle of the adjustment receptacle. Alternatively or additionally, the means for positioning the clamping device can also be provided on the laser unit.

In addition, the clamping device, in particular the clamping spring, can advantageously also be designed in one piece with the adjustment receptacle or the laser unit, in particular as an injection-molded component. Due to the absence of small parts, the laser unit can be arranged and aligned on or in the adjustment receptacle in a particularly simple, efficient and reproducible manner with reference to the preferred direction.

In order to exert the holding force by means of the clamping device, in particular by means of the clamping spring, the clamping device is advantageously brought into a clamped state by inserting the laser unit into the receptacle which is inserted at least partially axially through the adjustment receptacle. , so that the elasticity of the clamping device restrains the clamping and exerts a force on the laser unit. According to the invention, this force applied to the laser unit is used to hold the laser unit in the method steps of setting and aligning the laser unit with reference to the preferred direction on or in the adjustment receiver.

Furthermore, the clamping device, in particular the clamping spring, can have a shape and/or structure that is advantageous for optimal application of the holding force. In this case, for example, material thickening and/or shaping of the clamping spring can be considered, which impart advantageous elastic properties to the clamping spring, such as high stability, high resistance to curling and/or a small or large bearing surface.

In a preferred embodiment of the method according to the invention for mounting a rocking laser device, the laser unit is pressed against the adjustment receptacle by the clamping device with a constant pressing force.

Thus, in the method of the invention, it is advantageously ensured that the laser unit is held reliably on or in the adjustment receptacle during the method step of aligning the laser unit with reference to the preferential direction. Particularly advantageously, the pressing force (holding force) generated by the clamping device results in a frictional force, in particular a static frictional force, which inhibits the displacement of the laser unit on or in the adjustment receptacle, in particular its movement and/or rotation. In this case, frictional forces can act in particular between the laser unit and the adjustment receptacle and/or between the laser unit and the clamping device and/or between the clamping device and the adjustment receptacle (eg between the laser unit and the adjustment receptacle). when the clamping spring is integrally designed).

For the sake of clarity, and to simplify the following description of the method of the invention, the frictional forces, in particular the static frictional forces, between the laser unit and the adjustment receptacle are discussed below. However, the technical teachings of the embodiments of the method according to the invention can also be transferred analogously to designs of oscillating laser devices in which frictional forces, in particular static frictional forces, are present between the laser unit and the clamping device or between the clamping device. There is an interaction between the device and the adjustment receptacle.

In a preferred embodiment of the method according to the invention for mounting a swing laser device, the pressing force of the clamping device is designed such that between the laser unit and the adjustment holder and/or between the laser unit and the Frictional forces are generated between the clamping means and/or between the clamping means and the adjustment receptacle which allow the laser unit to move only under the influence of external forces.

According to the invention, the clamping device makes it possible to hold the laser unit at least temporarily during the method step of mounting the oscillating laser device on or in the adjustment receptacle. The resulting frictional force, in particular the static frictional force, inhibits the displacement of the laser unit on or in the adjustment receptacle, by means of which the adjusted setting position and/or of the laser unit on or in the adjustment receptacle is achieved Orientation does not change automatically, especially not due to gravity, for example.

In a preferred embodiment of the inventive method for mounting a swing laser device, the external force required to move the laser unit acts greater than the weight of the laser unit, in particular significantly greater than the weight of the laser unit.

In this way, it is advantageously achieved that if the laser unit is arranged in either direction on or in the adjustment receptacle with the clamping device, the external force required to move the laser unit in the method step of calibrating, in particular to overcome the The external force required for friction at least precludes gravity as the driving force for transposing the laser unit. "Greater than, especially significantly greater than, the gravity of the laser unit" means in particular that fluctuations in the gravity acting on the laser unit, especially vibrations, shaking, shocks, etc. due to installation conditions, will not cause the laser unit to directly change. bit. In particular, an external force effect that is "significantly greater than the weight of the laser unit" means a force effect that is greater, eg, in particular up to 2 times, advantageously up to 5 times, particularly advantageously up to 10 times, than the weight of the laser unit. This makes it possible to ensure that the calibrated laser unit retains its orientation on or in the adjustment receptacle reliably even in the event of vibrations, jolts, etc. caused by the installation conditions.

If the friction force between the adjustment receptacle and the laser unit, in particular the stiction force, is overcome due to the externally applied forces, in particular by those skilled in the art who mount the rocker laser device, the laser on or in the adjustment receptacle can be overcome. The units are transposed, and in particular the laser units are moved and/or rotated. The laser unit can then be calibrated with reference to the preferred direction. As soon as the externally applied force is reduced again, in particular less than the sliding friction force to be applied to keep the laser unit moving, the clamping device securely holds the laser unit on or in the adjustment receptacle again in adjustment OK, now in a changed direction.

The above-described design of the shape and/or structure of the clamping device, in particular the clamping spring, can be used particularly advantageously to influence the static and/or sliding friction force when the laser unit is displaced on or in the adjustment receptacle. In particular, a force distribution, in particular static friction and/or sliding friction, can be achieved by a targeted configuration of the clamping device, which advantageously facilitates a fine and precise alignment of the laser unit on or in the adjustment receptacle, in particular is its movement and/or rotation.

In a preferred embodiment of the method according to the invention for assembling a swivel laser device, the laser unit is adjusted to accommodate a position using means for positioning, in particular guide strips and/or webs and/or stop pins. It is calibrated in or on the part, in particular moving and/or rotating relative to the adjustment receptacle.

In this way, in the method of the invention a simple, fast and simultaneous precise alignment, in particular translational and/or rotational alignment of the laser unit on or in the adjustment receptacle can be achieved. Furthermore, other aids for calibration, such as a metric tape measure, etc., can advantageously be omitted, thereby further simplifying and speeding up the method for installation.

In a preferred embodiment of the method according to the invention for mounting a swing laser device, the laser unit is fastened to or in the adjustment receptacle by means of a rapidly hardening adhesive.

It is thus advantageously possible to fasten the laser unit on or in the adjustment receptacle in the final method step in a fast, form-fitting and/or cohesive manner, in particular permanently. Due to the short curing time, the risk of inadvertent movement and/or rotation of the laser unit during this method step, eg due to shock or vibration, is reduced.

In a preferred embodiment of the method according to the invention for mounting a swing laser device, the laser unit is fastened to or in the adjustment receptacle by means of a photohardening and/or thermosetting adhesive.

With photohardening and/or thermosetting adhesives, in the method step of fixing the laser unit on or in the adjustment receptacle, it can be achieved that the adhesive is exposed to light, in particular UV-light. Under the influence of temperature, and/or under the action of a certain temperature, targeted hardening occurs. Advantageously, the point in time at which the laser unit is fastened on or in the adjustment receptacle can be freely selected and controlled in this way by a person skilled in the art who installs the oscillating laser device.

In a preferred embodiment of the method according to the invention for mounting a pendulum laser device, the laser unit and the adjustment receptacle are at least partially enclosed, in particular encapsulated, for fixing by means of adhesive.

Particularly advantageously, in the method of the invention, the adhesive is suitably applied so that at least the laser unit and the adjustment receptacle, but preferably also the clamping device, are at least partially covered and/or surrounded, in particular encased seal up. This makes it possible to fasten the laser unit on or in the adjustment receptacle in a simple, quick and particularly stable manner. Preferably, by surrounding both the laser unit and the adjustment receptacle, in particular also the clamping device, a particularly stable, all-round form-fitting and cohesive fixing is achieved. In particular and particularly preferably, in the method step of fixing the laser unit on or in the adjustment receptacle, the adhesive is also introduced into the intermediate cavity between the laser unit and the adjustment receptacle, in particular into the at least partially Inserted axially into the receptacle of the adjustment receptacle and hardened there.

Furthermore, the exemplary embodiment shown in FIG. 2 and the other figures is not limited to the alignment and fixing of only one laser unit 24 on the rocking device 28 by means of the adjustment receptacle 30 . In an alternative embodiment of the subject matter of the present invention, using the same method according to the present invention, on an alternative rocking device 28 ′, for example, a plurality of laser units 24 , in particular to be aligned with one another, can also be used.

FIGS. 3 , 4 and 5 respectively show a detailed view of an embodiment of the adjustment receptacle 30 according to the invention known from FIG. 2 on which the laser unit 24 utilizes the clamping device 32 , with reference to the preferred direction In particular, reference is made to the vertical line 38, which is calibrated according to the method of the invention (FIGS. 4, 5), or also arranged and calibrated (FIG. 3). Here, in the method according to the invention, the clamping device 32 is used for a simplified arrangement and alignment of the laser unit 24 relative to the adjustment receptacle 30 . In the embodiment shown, the laser unit 24 is calibrated at least when the laser marking produced by means of the laser unit 24 , ie the marking line projected onto the object by means of the emitted laser surface 22 a in particular, is oriented in the direction of the vertical line 38 .

As shown in the exemplary embodiment shown in FIG. 3 , the adjustment receptacle 30 is arranged on a particularly horizontal projection 44 of the rocking device 28 according to the invention and consists of a base body 46 and a receptacle 48 for accommodating the laser unit 24 . , the receptacle passes axially through the base body 46 . The elastic leaf spring 32 a is held, in particular clamped, on the adjustment receptacle 30 by means of two material projections 52 (see in particular FIG. 5 ), resulting in the curvature of the otherwise linear leaf spring 32 a and thus in the leaf spring 32 a. An elastic stress is built up in the spring 32a, which overcomes the (further) deformation of the leaf spring 32a (see in particular Fig. 5).

A friction force, in particular a static friction force, is caused between the adjustment receptacle 30 and the laser unit 24 by this top pressure, which friction force allows the laser unit 24 to move only under the action of an external force. The resulting static friction force is in particular greater than the gravitational force of the laser unit 24 .

In this way, it is advantageously achieved that, in the method step of aligning the laser unit 24 on the adjustment holder 30 , what is required for the movement or displacement of the laser unit 24 , in particular for the movement and/or rotation of the laser unit 24 , is The external force action, ie the external force action required in particular to overcome the static friction, must be greater than the gravitational force of the laser unit 24 .

Specifically, in the illustrated embodiment, the leaf spring 32a exerts a static friction force designed to be approximately 10 times greater than the gravity of the laser unit 24 .

The laser unit 24 can be indexed, in particular moved and/or rotated, relative to the adjustment receptacle 30 once a force sufficient to overcome the stiction has been applied by the person skilled in the art performing the installation. If the externally applied force is reduced again, in particular less than the sliding friction force to be applied to keep the laser unit 24 moving, the leaf spring 32a will reliably keep the laser unit 24 on the adjustment receiver 30 in adjustment again. In the past, and now the direction has changed.

In order to align the laser unit 24 on or in the adjustment receptacle 30 , in addition to passing axially through the wall of the receptacle 48 of the adjustment receptacle 30 , provision is also made on the base body 46 of the adjustment receptacle 30 and on the laser unit 24 .
