In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below:
all directions or similar expressions such as "front", "back", "left", "right", "top", "bottom", "inner", "outer", "side", etc. are mainly used to refer to the directions of the drawings, and are only used to assist the description and understanding of the embodiments of the present invention, and are not used to limit the present invention.
The use of the terms a or an for the elements and components described throughout this disclosure are for convenience only and provide a general sense of the scope of the invention; in the present invention, it is to be understood that the singular includes plural unless it is obvious that it is meant otherwise.
Referring to fig. 1, a method for measuring a golf club head according to a preferred embodiment of the present invention includes collecting a profile of a semi-finished club head detection surface H to obtain a first reference surface H1 and a second reference surface H2, and calculating an intermediate value of a vertical distance between the first reference surface H1 and the second reference surface H2.
The club head semi-finished product detecting surface H may be a substantially flat surface on the golf club head 1, for example, a flat surface of a predetermined area on the back (back) of the golf club head 1, or a flat surface of a predetermined area on the sole (Toe) of the golf club head 1, and the worker may select a flat surface on an appropriate detecting portion according to different detecting requirements, which is not limited in the present invention. In the embodiment, the detecting surface H is located on the Face (Face) of the golf club head 1, so as to ensure that the Face meets the predetermined specification and has a good feeling.
For example, the stereoscopic Vision method (Stereo Vision) may be used to capture images of the detection surface H from different angles through two or more lenses, and the stereoscopic contour of the detection surface H may be obtained after the conventional triangulation method is used for calculation, or the Time of Flight (Time of Flight) principle may be used to obtain the distance and depth from the detection surface H by measuring the Time difference after the detection surface H is irradiated with laser or infrared light emitted from a sensor and receiving the reflected light of the detection surface H. For example, according to the present embodiment, the Structured Light principle is used, the Light collecting unit M can project the laser beam to the detecting surface H through diffraction of the grating to form a Light spot (Pattern), i.e., the Light collecting unit M can receive the Light spot code (Light Coding) on the detecting surface H to form the three-dimensional data of the detecting surface H, so as to obtain the three-dimensional profile of the detecting surface H, which is not limited by the present invention.
In detail, the golf club head 1 can be positioned so that the detection surface H faces the collecting unit M, for example, the golf club head 1 can be positioned by a jig, a saddle or a jig for collecting the detection surface H, the present invention is not limited thereto, and a worker can set the collecting range of the collecting unit M according to the position of the detection surface H by adjusting the type of a lens, the irradiation range of a laser, etc., for example, the detection surface H is located at a striking surface, the collecting unit M can collect the sweet spot of the striking surface as the detection surface H, in this embodiment, the collecting range of the collecting unit M can be a rectangular range with a length of 100mm and a width of 70mm, so as to ensure that the detection surface H of the golf club head 1 can be completely covered, and the detection surface H forms an included angle θ with respect to the laser beam projection path of the collecting unit M, wherein θ is less than or equal to 30 ° and less than or equal to 150 °, preferably the included angle θ is 90 °, so that the laser beam of the collecting unit M can be perpendicularly projected onto the detecting surface H, thereby improving the accuracy of collecting the detecting surface H. The three-dimensional contour of the detection surface H can form image data and input the image data to the arithmetic unit, which is known to those skilled in the art and will not be described herein. It should be noted that even if the detecting surface H is not 90 ° with respect to the laser beam projection path M, the computing unit may correct the image data of the detecting surface H, for example, if the two opposite ends of the detecting surface H should be the same plane, i.e., if the contour of the two opposite ends of the detecting surface H has a height difference, it may be determined that the detecting surface H is not 90 ° with respect to the laser beam projection path M, i.e., the detecting surface H may be corrected by the computing unit.
Referring to fig. 2 and 3, the first reference plane H1 and the second reference plane H2 respectively passing through two predetermined heights on the testing plane H can be obtained by the three-dimensional contour of the testing plane H, in detail, the testing plane H can have a plurality of convex portions and/or a plurality of concave portions, a plurality of planes can be obtained by collecting the three-dimensional contour of the testing plane H, the planes pass through the top surfaces of the convex portions and pass through the bottom surfaces of the concave portions, the planes are parallel to each other, thereby, two of the planes can be selected as the first reference plane H1 and the second reference plane H2, it is noted that, the golf club head 1 is usually formed by forging or casting and surface-treated, therefore, the convex portions and the concave portions of the testing plane H of the golf club head 1 do not completely protrude to form a single apex, or recessed to a single low point, that is, a raised rough plane is formed at the convex portion of the detection surface H, and a recessed rough plane is formed at the concave portion, which means three points having the same plane, so that a plane can be described by the three points, and thus, the first reference surface H1 or the second reference surface H2 can be obtained at the convex portion and the concave portion.
The operator can define two planes of the plurality of planes as the first reference plane H1 and the second reference plane H2 according to the measurement requirement, in this embodiment, two planes with the longest vertical distance from each other among the plurality of planes can be selected as the first reference plane H1 and the second reference plane H2, that is, the most convex part of the detection plane H can be selected as the first reference plane H1 and the most concave part of the detection plane H can be selected as the second reference plane H2, and for example, two planes with the shortest vertical distance from each other can be selected as the first reference plane H1 and the second reference plane H2, etc., which are not limited in the present invention.
After obtaining the first reference plane H1 and the second reference plane H2, an intermediate value of the vertical distance from the first reference plane H1 to the second reference plane H2 may be calculated to take a plane passing through the intermediate value as a standard plane H3, and the standard plane H3 is parallel to the first reference plane H1 and the second reference plane H2, whereby the flatness of the detection plane H may be judged by the standard plane H3. For example, the projecting distance and the recessed distance of each part on the detection surface H compared to the standard surface H3 can be obtained based on the standard surface H3, and the result can be expressed in numerical values, patterns, or the like, so that a worker can intuitively understand the flatness on the detection surface H and can judge whether the detection surface H meets the specification according to the predetermined specification standard.
Alternatively, it is also possible to determine whether the flatness of the detection surface H meets the specification by determining that a convex portion protruding from the standard surface H3 by a predetermined distance is an excessive protrusion, or that a concave portion recessed from the standard surface H3 by a predetermined distance is an excessive depression. In the present embodiment, the detection surface H is the face of the golf club head 1, the milling amount of the face of the golf club head 1 is 0.3mm, and when the unevenness before milling exceeds 0.2mm, there is a possibility that a milled surface remains, and preferably, the vertical distance between the plurality of planes and the standard surface H3 can be determined based on the standard surface H3, the convex portion protruding beyond 0.2mm in the plurality of planes is regarded as being too convex, and the concave portion recessed beyond 0.2mm in the plurality of planes is regarded as being too concave, and the result can be similarly represented in a pattern or the like, for example, regions exceeding 0.2mm, below 0.2mm, and ± 0.2mm in the outline image of the detection surface H can be represented by different color blocks, and a worker can quickly observe the distribution of the color blocks to determine whether the detection surface H is acceptable. It should be noted that, as can be understood by those skilled in the art, the detection surface H may have a plurality of grooves or an arc edge extending to the bottom, toe or blade adjacent to the periphery of the striking surface, the depth of the plurality of grooves is a known value after the striking surface of the golf club head 1 is formed, and the position of the arc edge on the detection surface H is also fixed, so that after the detection surface H is collected, the recesses formed by the plurality of grooves and the arc edge can be filtered in advance by the arithmetic unit to avoid influencing the interpretation, or the worker can also know the positions of the plurality of grooves and the arc edge on the contour image of the detection surface H without making an erroneous judgment.
In summary, according to the golf club head measuring method of the present invention, after the contour of the detection surface of the golf club head is collected, the first reference surface and the second reference surface can be obtained by the plurality of protrusions and the plurality of recesses, so as to determine the standard surface of the detection surface, and whether the flatness of the detection surface meets the standard can be determined by the standard surface, thereby avoiding errors caused by manual interpretation, achieving the effect of measurement accuracy, replacing manual operation with computerization, and achieving the effect of reducing labor cost.
Although the present invention has been disclosed with reference to the above preferred embodiments, it should be understood that the scope of the present invention is not limited thereto, and those skilled in the art will appreciate that various changes and modifications can be made to the above embodiments without departing from the spirit and scope of the present invention.
