Background

In the production of photovoltaic cells, it is often necessary to use baskets to store the cells and to transfer the cells from some process equipment to other process equipment by transferring the baskets. For example, in a multi-stage process of manufacturing the battery cells, such as etching, diffusion, etc., a larger throughput can be achieved by storing the battery cells using the basket, and carrying the basket using an AGV or the like.

In the known technique, there are requirements of different orientations of the openings of the basket when facing the feeding and discharging lines of different battery pieces. For example, in the PSG (Phospho SI L ICATE GLASS ) removing machine and BSG (Boro SI L ICATE GLASS ) removing machine, the requirements for the orientation of the opening are different when the basket is fed and when the basket is discharged. In known solutions, it is common to add a traversing mechanism to effect the change of orientation of the opening of the basket. But this approach is relatively inefficient and affects throughput.

Referring to fig. 1 to 3, the transfer device 400 (hereinafter, for convenience of description, sometimes referred to simply as "transfer device 400") for the basket 13 according to the embodiment is used in the production of photovoltaic cells. The transfer device 400 is used to transfer the basket 13. The basket 13 is a carrier for mounting the battery cells 12 (also referred to as "silicon wafer"). The basket 13 includes an upper substrate 13a, a lower substrate 13b, and a plurality of connection bars 13c having both ends connected to the upper substrate 13a and the lower substrate 13b, respectively. The connecting rod 13c is provided with a plurality of engaging grooves (not shown) in the axial direction, and the engaging grooves of the connecting rods 13c hold the battery cells 12 together. The plurality of connection bars 13c are substantially U-shaped around, and are formed with openings 401 allowing the battery pieces 12 to enter the card slots of the basket 13 or to be removed from the card slots of the basket 13. In order to match the transfer device 400 of the embodiment, positioning holes (not numbered) or positioning protrusions are formed on the outer side of the upper substrate 13a and the outer side of the lower substrate 13b of the basket 13, respectively. Further, a stopper hole (no reference numeral) or a stopper protrusion for suppressing the rotation of the basket 13 in the circumferential direction is formed on the outer side of one of the upper base plate 13a and the lower base plate 13b of the basket 13.

The transfer device 400 according to the embodiment includes a robot 402 and a jig portion 403 attached to the end of the robot 402. The robot 402 is a conventional robot 402 such as a three-axis or more manipulator or an articulated robot, and is typically a six-axis robot. The clamp portion 403 has a first clamping jaw 404, a second clamping jaw 405, and a clamping driver 406, the second clamping jaw 405 being opposite to the first clamping jaw 404 in a first direction, the clamping driver 406 driving at least one of the first clamping jaw 404 and the second clamping jaw 405 in the first direction. The first direction is not particularly limited, and if the basket 13 is used as a reference, the first direction is the height direction of the basket 13, that is, the extending direction of the connection rod 13 c. The clamp portion 403 further includes a first rotary support 407, a second rotary support 408, and a rotary drive 409. The first rotary support 407 is mounted to one of the first jaw 404 and the second jaw 405. A second rotary support 408 is mounted to the other of the first jaw 404 and the second jaw 405. The second rotary support 408 is opposite to the first rotary support 407 in the first direction. The rotation driving member 409 drives at least one of the first rotation supporting member 407 and the second rotation supporting member 408 to rotate. The basket 13 is clamped between the first rotary support 407 and the second rotary support 408 in a first direction.

The transfer device 400 is able to change the orientation of the openings 401 of the basket 13 more efficiently. Specifically, by using the robot 402 and providing the clamp portion 403 with the first clamp jaw 404 and the second clamp jaw 405, the basket 13 can be easily clamped. For example, when the basket 13 of the sheet feeder is at the blanking position, the robot 402 moves to the gripping position, and the gripping driver 406 drives at least one of the first gripping jaw 404 and the second gripping jaw 405 to open the first gripping jaw 404 and the second gripping jaw 405 of the grip portion 403 and grip the upper substrate 13a and the lower substrate 13b of the basket 13, whereby the basket 13 can be gripped easily. By attaching the first rotary support 407 and the second rotary support 408 to the first jaw 404 and the second jaw 405 and driving at least one of the first rotary support 407 and the second rotary support 408 by the rotary driver 409, the basket 13 can be driven to rotate by a predetermined angle (for example, 180 °) while holding the basket 13, and the direction of the opening 401 of the basket 13 can be changed while transferring the basket 13. Thus, the transfer device 400 of the embodiment can change the orientation of the opening 401 of the basket 13 more efficiently.

Moreover, with the appearance of the battery pieces 12 of the half pieces and the full pieces, the variety of the flower basket 13 is increased, and the known traversing mechanism is difficult to be compatible with different flower baskets 13. In the transfer device 400 of the embodiment, since the first jaw 404 and the second jaw 405 can be opened or closed each other, by changing the opening stroke or the closing stroke of the first jaw 404 and the second jaw 405, for example, it is possible to easily cope with the flower baskets 13 having different heights. Further, since the clamp portion 403 mainly clamps the upper and lower substrates 13a and 13b of the basket 13 without limiting the longitudinal and width directions of the basket 13, the transfer device 400 of the embodiment can also be compatible with more types of baskets 13 differing in the longitudinal and/or width directions.

With continued reference to fig. 2 and 3, the clamp portion 403 further includes a base 410, and the clamp portion 403 is mounted to the end of the robot 402 via the base 410. The structure of the base 410 is not particularly limited, and for example, the base 410 may have a long plate shape, and for example, an aluminum profile having a mounting groove 411 on the outer periphery of the base 410 may be selected. Taking the base 410 of the aluminum profile as an example, the base 410 is a rectangular aluminum profile having a cross section of 80mm in length and 40mm in width. Mounting slots 411 are formed on both sides of the long side and both sides of the short side of the cross section of the base 410, respectively, and the mounting slots 411 extend in the longitudinal direction of the entire base 410. The first jaw 404 is mounted to one end of the base 410 in a first direction. The second jaw 405 is slidably mounted to the other end of the base 410 in the first direction. The clamp drive 406 is mounted to the base 410 and is connected to the second clamp jaw 405. The first clamping jaw 404 is, for example, in the form of a long plate, and when the base 410 is an aluminum profile, the first clamping jaw 404 is attached to an end portion of the aluminum profile in the longitudinal direction. The second holding jaw 405 is also, for example, in a long plate shape, and is slidably mounted to the other end of the base 410 in the first direction by a linear guide mechanism 412. The type of the linear guide 412 is not particularly limited, and for example, a linear slide guide, a linear guide shaft guide, and the like may be selected. For example, in case that the base 410 selects an aluminum profile, one linear guide rail guide mechanism may be installed at both sides of the short side of the cross section of the base 410, respectively, and the linear guide rail of the linear guide rail guide mechanism may be directly locked to the installation slot 411 of the short side of the base 410 by, for example, a screw and a T-bolt. A link plate 413 is mounted on a slider (no reference numeral) of each linear slide guide mechanism, and the second clamping jaw 405 is connected to two link plates 413. Thereby, the second clamping jaw 405 can slide on the base 410 in the first direction. The clamping drive 406 may be a pneumatic cylinder or a motor, in which case the output end of the clamping drive 406 (one end of the piston rod) is directly connected to the second clamping jaw 405. In the case of selecting the motor, for example, a slide table module based on a single shaft driven by the motor, or the like may be selected. Additionally, the clamp drive 406 may be adjustably mounted to the base 410 in a first direction. For example, in the case where the base 410 selects an aluminum profile, the grip driving piece 406 is mounted into the mounting slot 411 of the long side of the cross section of the aluminum profile through the mounting plate 414, and the mounting position of the grip driving piece 406 can be easily adjusted in the first direction along the mounting slot 411 of the aluminum profile by loosening the mounting screw of the mounting plate 414.

Thus, the second clamping jaw 405 is at one end in the length direction of the base 410, mounted to two linear guide mechanisms 412 located at both sides of the short side of the cross section of the base 410 via two connection plates 412 located at both sides of the short side of the cross section of the base 410. In addition, the end of the second clamping jaw 405 near the base 410 is connected to the output end of a cylinder as a clamping drive 406 mounted on one side of the long side of the cross section of the base 410.

Thereby, the clamp portion 403 can drive the second clamp jaw 405 in the first direction toward or away from the first clamp jaw 404 by the clamp drive 406 with the first clamp jaw 404 as a reference, so that the basket 13 can be clamped or the basket 13 can be unclamped.

In addition, although the manner in which the second jaw 405 approaches or separates from the first jaw 404 in the first direction with reference to the first jaw 404 is described, it is not limited thereto. For example, the first clamping jaw 404 may be slidably mounted to the base 410 along the first direction, and the clamping driver 406 may be connected to the first clamping jaw 404 and the second clamping jaw 405, respectively. Further, for example, the first clamping jaw 404 and the second clamping jaw 405 are each mounted to the base 410 by a linear guide mechanism 412, such as a linear slide guide mechanism. Thereby, the first jaw 404 and the second jaw 405 can slide in the first direction, respectively. The clamping drive 406 may, for example, be a cylinder with hinges at both ends, the clamping drive 406 being hinged at both ends to the first clamping jaw 404 and the second clamping jaw 405, respectively. Thus, when the cylinder as the clamp drive 406 is extended, the first clamp jaw 404 and the second clamp jaw 405 can be opened, and when the cylinder as the clamp drive 406 is retracted, the first clamp jaw 404 and the second clamp jaw 405 can be closed. The clamp portion 403 can reliably clamp the basket 13 when the first clamp jaw 404 and the second clamp jaw 405 are closed.

With continued reference to fig. 2 and 3, as described above, the clamp portion 403 further includes the first rotary support 407, the second rotary support 408, and the rotary drive 409, whereby the clamp portion 403 can clamp the basket 13 and simultaneously drive the basket 13 to rotate by a predetermined angle. Specifically, the first rotary support 407 is, for example, a substantially disc-shaped plate, and the first rotary support 407 is rotatably attached to the first jaw 404 by a bearing (no reference numeral) capable of receiving axial pressure, such as a deep groove ball bearing, an angular contact bearing, a cylindrical roller bearing, or the like. For example, the first rotary support 407 may be mounted to the distal end of the first jaw 404. A rotary drive 409 is mounted to the second jaw 405, the rotary drive 409 may be mounted to a distal end of the second jaw 405, opposite the first jaw 404 in a first direction, for example. The second rotation support 408 is connected to a rotation driving member 409 and is driven to rotate by the rotation driving member 409. The second rotary support 408 is, for example, substantially plate-shaped, and the second rotary support 408 and the first rotary support 407 coaxially rotate.

The first jaw 404 and the second jaw 405 clamp the basket 13 via a first rotary support 407 and a second rotary support 408, respectively. More specifically, the first clamping jaw 404 and the second clamping jaw 405 clamp the basket 13 such that the first rotary support 407 abuts against the lower base plate 13b of the basket 13 and the second rotary support 408 abuts against the upper base plate 13a of the basket 13. Since the first rotary support 407 and the second rotary support 408 are rotatable, when at least one of the first rotary support 407 and the second rotary support 408 is driven by the rotary driver 409, the whole basket 13 is also driven by the rotary driver 409.

The rotation driving member 409 may be an air cylinder, and the second rotation supporting member 408 is mounted to the rotation driving member 409. Specifically, the rotation driving member 409 may be a rotation cylinder, and the second rotation supporting member 408 is directly mounted to the rotation cylinder as the rotation driving member 409.

The rotation driving member 409 may be a motor, and the rotation driving member 409 is connected to the second jaw 405 through a rotation transmission mechanism. For example, the second rotary support 408 may be rotatably mounted to the second jaw 405 by a bearing capable of withstanding axial pressure, such as a deep groove ball bearing, an angular contact bearing, a cylindrical roller bearing, or the like, as the first rotary support 407. The rotation transmission mechanism is not particularly limited, and for example, a belt transmission mechanism, a gear transmission mechanism, or the like may be selected.

The rotation driving member 409 may be connected to both the first rotation supporting member 407 and the second rotation supporting member 408. For example, in the case where the rotation driving member 409 selects the motor, it may be connected to the first rotation supporting member 407 and the second rotation supporting member 408, respectively, through a belt transmission mechanism.

The first positioning portion 415 is formed on a surface of the first rotary support 407 facing the second rotary support 408. The second rotary support 408 has a second positioning portion 416 formed on a surface thereof facing the first rotary support 407. The first positioning portion 415 and the second positioning portion 416 together position the basket 13. The first positioning portion 415 and the second positioning portion 416 are respectively matched with positioning holes or positioning protrusions formed on the outer side of the upper substrate 13a and the outer side of the lower substrate 13b of the basket 13. For example, in the case of forming a positioning hole in the basket 13, the first positioning portion 415 and the second positioning portion 416 are positioning projections such as positioning posts, respectively. In the case where the first positioning portion 415 and the second positioning portion 416 are positioning posts, respectively, the first positioning portion 415 and the second positioning portion 416 are coaxial in the first direction. In the case of forming the positioning projection on the basket 13, the first positioning portion 415 and the second positioning portion 416 are, for example, positioning holes or the like, respectively.

At least one of the first rotary support 407 and the second rotary support 408 is formed with a rotation limiting portion 417, and the rotation limiting portion 417 limits the basket 13 in the circumferential direction of the basket 13. The rotation limiting portion 417 also matches a limiting hole or a limiting protrusion for inhibiting circumferential rotation of the basket 13. For example, in the case where the upper base plate 13a of the basket 13 forms a limit hole, the rotation limit portion 417 may be a limit post formed at the second rotation support 408. The formation position of the rotation restricting portion 417 in the second rotation support 408 is not particularly limited as long as it is different from the position formed by the second positioning portion 416 in the second rotation support 408.

The rotation limiting portion 417 may be formed on the first rotation support 407, or may be formed on the first rotation support 407 and the second rotation support 408, respectively.

In the transfer device 400 according to the embodiment, the basket 13 can be easily gripped by using the robot 402 and providing the clamp portion 403 with the first clamp jaw 404 and the second clamp jaw 405. By attaching the first rotary support 407 and the second rotary support 408 to the first jaw 404 and the second jaw 405 and driving at least one of the first rotary support 407 and the second rotary support 408 by the rotary driver 409, the basket 13 can be driven to rotate by a predetermined angle (for example, 180 °) while holding the basket 13, thereby changing the orientation of the opening 401 of the basket 13 while transferring the basket 13. Thus, the transfer device 400 of the embodiment can change the orientation of the opening 401 of the basket 13 more efficiently.

In the transfer device 400 according to the embodiment, by attaching the first gripper 404, the second gripper 405, and the gripping driver 406 to the same base 410, the first gripper 404, the second gripper 405, and the gripping driver 406 can be more compactly arranged. By using an aluminum profile as the base 410, the first clamping jaw 404, the second clamping jaw 405 and the clamping drive 406 can be adjusted more easily, for example, the position of the clamping drive 406 can be adjusted more easily in the first direction.

In the transfer device 400 according to the embodiment, by using an aluminum profile, which can be used as a mounting surface on both the long side and the short side of the cross section, as the base 410, and by attaching the linear guide mechanism 412 to the short side, and attaching the clamp drive 406 to the long side, and by connecting the second clamp claw 405 to the linear guide mechanism 412 and the clamp drive 406, respectively, the entire clamp mechanism can be made more compact. Further, from a force-receiving perspective, since one end of the second clamping jaw 405 in the length direction is connected to the clamping drive member 406, the other end of the second clamping jaw 405 in the length direction is cantilevered, which may cause the second clamping jaw 405 to deform under force. In the transfer device 400 according to the embodiment, by attaching the linear guide mechanism 412 to the short side and positioning the two connection plates 412 at the cantilever-like end near the second jaw 405 with respect to the clamp driver 406, the two connection plates 412 can be used as the reinforcing plate of the second jaw 405, thereby improving the clamp strength of the second jaw 405 and suppressing the stress deformation of the second jaw 405. Further, since the linear guide mechanism 412 and the two connection plates 412 can be mounted on the short side of the base 410, an additional mounting space is not required, and the base 410 as a whole does not become redundant.

In the transfer device 400 according to the embodiment, the robot 402 can be driven more accurately by using the first gripper 404 as a reference and causing the gripper driver 406 to drive the second gripper 405. For example, the basket 13 is typically supported on a conveyor line with the lower base plate 13b as a reference, i.e., the basket 13 is transported with the lower base plate 13 b. In the transfer device 400 according to the embodiment, by using the first jaw 404 positioned on the side of the lower substrate 13b of the basket 13 as a reference, even if the basket 13 is different in height, the tip of the robot 402 can be accurately driven to a position where the basket 13 can be held without changing the trajectory of the robot 402.

In the transfer device 400 according to the embodiment, the first rotary support 407 is adaptively rotatably attached to the first jaw 404, and the second rotary support 408 is driven by the rotary driver 409, so that the basket 13 can be smoothly rotated. By driving the basket 13 using a rotary cylinder, the structure of the rotary driving can be simplified.

In the transfer device 400 according to the embodiment, the first positioning portion 415 and the second positioning portion 416 are formed in the first rotary support 407 and the second rotary support 408, respectively, so that the basket 13 can be reliably held and positioned. By forming the rotation limiting portion 417 on at least one of the first rotation support 407 and the second rotation support 408, loosening or the like of the basket 13 occurring during rotation of the basket 13 can be suppressed. The reliability of rotation is improved.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the embodiments, the scope of which is defined in the claims and their equivalents.
