Description

Technical Field

[0001] The utility model relates to but is not limited to the technical field of photovoltaic cell production devices, and in particular to a transfer device for flower baskets. Background Art

[0002] In the production process of photovoltaic cells, flower baskets are often needed to store cells, and by transferring the flower baskets, cells can be transferred from some process equipment to other process equipment. For example, in the multi-stage process of cell preparation, such as etching, diffusion and other processes, by using flower baskets to store cells and using AGV vehicles to transport the flower baskets, greater production capacity can be achieved.

[0003] In the known technologies, when facing different battery cell loading and unloading lines, there are different requirements for the orientation of the opening of the flower basket. For example, in the PSG (Phospho Si l icate Glass) removal machine and the BSG (Boro Si l icate Glass) removal machine, the orientation of the opening when loading and unloading the flower basket is different. In the known solutions, a transverse movement mechanism is usually added to change the orientation of the opening of the flower basket. However, this method is relatively inefficient and will affect production capacity. Utility Model Content

[0024] Reference Figures 1 to 3, a transfer device 400 for a flower basket 13 of an embodiment (for the sake of convenience, sometimes referred to as "transfer device 400" below) is used in the production of photovoltaic cells. The transfer device 400 is used to transfer the flower basket 13. The flower basket 13 is a carrier for carrying a battery cell 12 (also called a "silicon wafer"). The flower basket 13 includes an upper substrate 13a, a lower substrate 13b, and a plurality of connecting rods 13c connected to the upper substrate 13a and the lower substrate 13b at both ends. The connecting rod 13c is provided with a plurality of slots (not shown) along the axial direction, and the slots of each connecting rod 13c jointly hold the battery cell 12. The plurality of connecting rods 13c are generally surrounded in a U shape, and an opening 401 is formed to allow the battery cell 12 to enter the slot of the flower basket 13 or be removed from the slot of the flower basket 13. In order to match the transfer device 400 of the embodiment, positioning holes (not marked with reference numerals) 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 flower basket 13. In addition, a limiting hole (not marked with a reference numeral) or a limiting protrusion for preventing the flower basket 13 from rotating in the circumferential direction is formed on the outer side of one of the upper base plate 13 a or the lower base plate 13 b of the flower basket 13 .

[0025] The transfer device 400 of the embodiment includes: a robot 402 and a clamp part 403 installed at the end of the robot 402. The robot 402 is an existing robot 402 such as a manipulator with more than three axes or a multi-joint robot, and is typically a six-axis robot. The clamp part 403 has a first clamp 404, a second clamp 405, and a clamping drive 406. The second clamp 405 is opposite to the first clamp 404 along a first direction, and the clamping drive 406 drives at least one of the first clamp 404 and the second clamp 405 along the first direction. The first direction is not particularly limited. If the flower basket 13 is used as a reference, the first direction is the height direction of the flower basket 13, that is, the extension direction of the connecting rod 13c. In addition, the clamp part 403 also has a first rotating support 407, a second rotating support 408, and a rotating drive 409. The first rotating support 407 is installed to one of the first clamp 404 and the second clamp 405. The second rotating support member 408 is mounted to the other of the first clamping jaw 404 and the second clamping jaw 405. The second rotating support member 408 is opposite to the first rotating support member 407 along the first direction. The rotating driving member 409 drives at least one of the first rotating support member 407 and the second rotating support member 408 to rotate. The flower basket 13 is clamped between the first rotating support member 407 and the second rotating support member 408 along the first direction.

[0026] The transfer device 400 can more efficiently change the orientation of the opening 401 of the flower basket 13. Specifically, by using the robot 402 and making the clamping part 403 have the first clamping claw 404 and the second clamping claw 405, the flower basket 13 can be easily clamped. For example, when the flower basket 13 of the unloader is in the unloading position, the robot 402 moves to the clamping position, and the clamping driving member 406 drives at least one of the first clamping claw 404 and the second clamping claw 405 to open the first clamping claw 404 and the second clamping claw 405 of the clamping part 403, and clamp the upper substrate 13a and the lower substrate 13b of the flower basket 13, thereby making it easy to clamp the flower basket 13. By installing the first rotating support 407 and the second rotating support 408 on the first clamping jaw 404 and the second clamping jaw 405, and driving at least one of the first rotating support 407 and the second rotating support 408 through the rotating driving member 409, the flower basket 13 can be driven to rotate by a specified angle (for example, 180 degrees) while clamping the flower basket 13, so as to change the direction of the opening 401 of the flower basket 13 while transferring the flower basket 13. Therefore, the transfer device 400 of the embodiment can change the direction of the opening 401 of the flower basket 13 more efficiently.

[0027] Moreover, with the emergence of "half-cell" and "full-cell" battery cells 12, the types of flower baskets 13 are increasing, and the known transverse shifting mechanism is difficult to be compatible with different flower baskets 13. In the transfer device 400 of the embodiment, since the first clamping jaw 404 and the second clamping jaw 405 can be opened or closed with each other, by changing the opening stroke or closing stroke of the first clamping jaw 404 and the second clamping jaw 405, it is easy to be compatible with, for example, flower baskets 13 of different heights. Moreover, since the clamping part 403 mainly clamps the upper substrate 13a and the lower substrate 13b of the flower basket 13, and does not limit the length direction and width direction of the flower basket 13, the transfer device 400 of the embodiment can also be compatible with more types of flower baskets 13 with different length directions and / or width directions.

[0028] Continue to refer to Figure 2 , Figure 3, the fixture part 403 also includes a base 410, and the fixture part 403 is installed to the end of the robot 402 through the base 410. The structure of the base 410 is not particularly limited. For example, the base 410 can be in the shape of a long plate. In addition, the base 410 can also select, for example, an aluminum profile with a mounting groove 411 on the periphery. Taking the base 410 of the aluminum profile as an example, for example, the base 410 is a rectangular aluminum profile with a cross-section length of 80 mm and a width of 40 mm. The two sides of the long side and the two sides of the short side of the cross-section of the base 410 are respectively formed with mounting grooves 411, and the mounting grooves 411 extend along the length direction of the entire base 410. The first clamping jaw 404 is installed to one end of the first direction of the base 410. The second clamping jaw 405 is slidably installed to the other end of the first direction of the base 410 along the first direction. The clamping drive member 406 is installed to the base 410 and connected to the second clamping jaw 405. The first clamping jaw 404 is, for example, in the shape of a long plate. When the base 410 is made of aluminum, the first clamping jaw 404 is mounted to the end of the length direction of the aluminum. The second clamping jaw 405 is also, for example, in the shape of a long plate, and is slidably mounted to the other end of the first direction of the base 410 through a linear guide mechanism 412 along the first direction. The type of the linear guide mechanism 412 is not particularly limited, for example, a linear guide rail guide mechanism, a linear guide shaft guide mechanism, etc. can be selected. For example, when the base 410 is made of aluminum, a linear guide rail guide mechanism can be installed on both sides of the short side of the cross section of the base 410, and the linear guide rail of the linear guide rail guide mechanism is directly locked to the mounting groove 411 on the short side of the base 410 by, for example, screws and T-bolts. Connecting plates 413 are respectively installed on the sliders (not marked with reference numerals) of each linear guide rail guide mechanism, and the second clamping jaw 405 is connected to the two connecting plates 413. As a result, the second clamping jaw 405 can slide along the first direction on the base 410. The clamping drive 406 can be selected from a cylinder or a motor. In the case of selecting a cylinder, the output end (one end of the piston rod) of the clamping drive 406 is directly connected to the second clamp 405. In the case of selecting a motor, for example, a single-axis slide module driven by a motor can be selected. In addition, the clamping drive 406 can be mounted on the base 410 in an adjustable manner along the first direction. For example, in the case where the base 410 selects an aluminum profile, the clamping drive 406 is installed in the mounting groove 411 on the long side of the cross section of the aluminum profile through the mounting plate 414. By loosening the mounting screws of the mounting plate 414, the mounting position of the clamping drive 406 can be easily adjusted along the mounting groove 411 of the aluminum profile along the first direction.

[0029] Thus, the second clamping jaw 405 is located at one end in the length direction of the base 410, and is mounted to two linear guide mechanisms 412 located on both sides of the short side of the cross section of the base 410 via two connecting plates 412 located on both sides of the short side of the cross section of the base 410. In addition, one end of the second clamping jaw 405 close to the base 410 is connected to the output end of the cylinder as the clamping drive member 406 installed on one side of the long side of the cross section of the base 410.

[0030] Thus, the clamping part 403 can use the first clamping jaw 404 as a reference and drive the second clamping jaw 405 to approach or move away from the first clamping jaw 404 along the first direction through the clamping driving member 406 , thereby clamping the flower basket 13 or releasing the flower basket 13 .

[0031] In addition, although the method in which the second clamping jaw 405 approaches or moves away from the first clamping jaw 404 along the first direction with the first clamping jaw 404 as the reference is described, it is not limited to this. For example, the first clamping jaw 404 can also be slidably mounted to the base 410 along the first direction, and the clamping drive 406 is 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 both mounted on the base 410 through a linear guide mechanism 412 such as a linear slide guide mechanism. As a result, the first clamping jaw 404 and the second clamping jaw 405 can slide respectively along the first direction. The clamping drive 406 can, for example, be a cylinder with hinged joints at both ends, and the two ends of the clamping drive 406 are respectively hinged to the first clamping jaw 404 and the second clamping jaw 405. Thus, when the cylinder as the clamping driving member 406 extends, the first clamping jaw 404 and the second clamping jaw 405 can be opened, and when the cylinder as the clamping driving member 406 retracts, the first clamping jaw 404 and the second clamping jaw 405 can be closed. When the first clamping jaw 404 and the second clamping jaw 405 are closed, the clamping part 403 can reliably clamp the flower basket 13.

[0032] Continue to refer to Figure 2 , Figure 3As described above, the clamping part 403 further includes a first rotating support member 407, a second rotating support member 408, and a rotating drive member 409, so that the clamping part 403 can drive the flower basket 13 to rotate at a predetermined angle while clamping the flower basket 13. Specifically, the first rotating support member 407 is, for example, a substantially disc-shaped plate, and the first rotating support member 407 is rotatably mounted to the first clamping jaw 404 through a bearing (not marked with a reference numeral) such as a deep groove ball bearing, an angular contact bearing, a cylindrical roller bearing, etc. that can withstand axial pressure. For example, the first rotating support member 407 can be mounted to the distal end of the first clamping jaw 404. The rotating drive member 409 is mounted to the second clamping jaw 405, and the rotating drive member 409 can be mounted to the distal end of the second clamping jaw 405, and is opposite to the first clamping jaw 404 along the first direction. The second rotating support member 408 is connected to the rotating drive member 409 and is driven by the rotating drive member 409 to rotate. The second rotation support 408 is, for example, substantially plate-shaped, and the second rotation support 408 and the first rotation support 407 rotate coaxially.

[0033] The first clamping jaw 404 and the second clamping jaw 405 clamp the flower basket 13 via the first rotating support member 407 and the second rotating support member 408, respectively. More specifically, the first clamping jaw 404 and the second clamping jaw 405 clamp the flower basket 13 in such a manner that the first rotating support member 407 abuts against the lower base plate 13b of the flower basket 13 and the second rotating support member 408 abuts against the upper base plate 13a of the flower basket 13. Since the first rotating support member 407 and the second rotating support member 408 are rotatable, when at least one of the first rotating support member 407 and the second rotating support member 408 is driven by the rotating driving member 409, the entire flower basket 13 is also driven by the rotating driving member 409.

[0034] The rotary driving member 409 may be a cylinder, and the second rotary supporting member 408 is mounted to the rotary driving member 409. Specifically, the rotary driving member 409 may be a rotary cylinder, and the second rotary supporting member 408 is directly mounted to the rotary cylinder serving as the rotary driving member 409.

[0035] In addition, the rotary drive member 409 may also be a motor, and the rotary drive member 409 is connected to the second clamping jaw 405 through a rotary transmission mechanism. For example, the second rotary support member 408 may be rotatably mounted to the second clamping jaw 405 through a bearing capable of withstanding axial pressure, such as a deep groove ball bearing, an angular contact bearing, a cylindrical roller bearing, etc., like the first rotary support member 407. In addition, the rotary transmission mechanism is not particularly limited, and for example, a belt transmission mechanism, a gear transmission mechanism, etc. may be selected.

[0036] It should be noted that the rotary drive member 409 can also be connected to the first rotary support member 407 and the second rotary support member 408. For example, when the rotary drive member 409 is a motor, it can be connected to the first rotary support member 407 and the second rotary support member 408 through a belt transmission mechanism.

[0037] A first positioning portion 415 is formed on a surface of the first rotating support member 407 that is opposite to the second rotating support member 408. A second positioning portion 416 is formed on a surface of the second rotating support member 408 that is opposite to the first rotating support member 407. The first positioning portion 415 and the second positioning portion 416 jointly position the flower 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 flower basket 13. For example, in the case where a positioning hole is formed on the flower basket 13, the first positioning portion 415 and the second positioning portion 416 are respectively positioning protrusions such as positioning columns. In the case where the first positioning portion 415 and the second positioning portion 416 are respectively positioning columns, the first positioning portion 415 and the second positioning portion 416 are coaxial along the first direction. In the case where a positioning protrusion is formed on the flower basket 13, the first positioning portion 415 and the second positioning portion 416 are respectively, for example, positioning holes.

[0038] In addition, at least one of the first rotating support member 407 and the second rotating support member 408 is formed with a rotation limiting portion 417, and the rotation limiting portion 417 limits the flower basket 13 along the circumference of the flower basket 13. The rotation limiting portion 417 also matches the limiting hole or limiting protrusion used to inhibit the circumferential rotation of the flower basket 13. For example, in the case where the upper substrate 13a of the flower basket 13 is formed with a limiting hole, the rotation limiting portion 417 can be a limiting column formed on the second rotating support member 408. The formation position of the rotation limiting portion 417 on the second rotating support member 408 is not particularly limited, as long as it is different from the position where the second positioning portion 416 in the second rotating support member 408 is formed.

[0039] It should be noted that the rotation limiting portion 417 may also be formed on the first rotation supporting member 407 , or formed on the first rotation supporting member 407 and the second rotation supporting member 408 respectively.

[0040] In the transfer device 400 of the embodiment, by using the robot 402 and providing the clamping part 403 with the first clamping claw 404 and the second clamping claw 405, the flower basket 13 can be easily clamped. By installing the first rotating support 407 and the second rotating support 408 on the first clamping claw 404 and the second clamping claw 405, and driving at least one of the first rotating support 407 and the second rotating support 408 by the rotating driving member 409, the flower basket 13 can be clamped and driven to rotate by a predetermined angle (for example, 180 degrees), thereby changing the direction of the opening 401 of the flower basket 13 while transferring the flower basket 13. Therefore, the transfer device 400 of the embodiment can change the direction of the opening 401 of the flower basket 13 more efficiently.

[0041] In the transfer device 400 of the embodiment, the first clamping jaw 404, the second clamping jaw 405, and the clamping driver 406 are mounted on the same base 410, so that the first clamping jaw 404, the second clamping jaw 405, and the clamping 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 driver 406 can be more easily adjusted, for example, the position of the clamping driver 406 can be more easily adjusted along the first direction.

[0042] In the transfer device 400 of the embodiment, by using an aluminum profile whose long side and short side of the cross section can both serve as mounting surfaces as the base 410, installing the linear guide mechanism 412 on the short side, installing the clamping driver 406 on the long side, and connecting the second clamping jaw 405 to the linear guide mechanism 412 and the clamping driver 406, the clamping mechanism as a whole can be made more compact. In addition, from the perspective of force, since one end of the second clamping jaw 405 in the longitudinal direction is connected to the clamping driver 406, and the other end of the second clamping jaw 405 in the longitudinal direction is cantilevered, this may cause the second clamping jaw 405 to deform under force. In the transfer device 400 of the embodiment, by installing the linear guide mechanism 412 on the short side and positioning the two connecting plates 412 at one end of the cantilevered shape close to the second clamping jaw 405 relative to the clamping drive member 406, the two connecting plates 412 can be used as reinforcing plates of the second clamping jaw 405, thereby improving the clamping strength of the second clamping jaw 405 and suppressing the stress deformation of the second clamping jaw 405. In addition, since the linear guide mechanism 412 and the two connecting plates 412 can be installed on the short side of the base 410, no additional installation space is required, and the base 410 as a whole will not become redundant.

[0043] In the transfer device 400 of the embodiment, by using the first clamping jaw 404 as a reference, the clamping driving member 406 drives the second clamping jaw 405, so that the robot 402 can be driven more accurately. For example, the flower basket 13 is usually supported on the conveyor line by the lower base plate 13b, that is, the flower basket 13 is used as a reference during transportation. In the transfer device 400 of the embodiment, by also using the first clamping jaw 404 located on one side of the lower base plate 13b of the flower basket 13 as a reference, even if it corresponds to different flower baskets 13 with different heights, it is possible to accurately drive the end of the robot 402 to a position where the flower basket 13 can be clamped without changing the trajectory of the robot 402.

[0044] In the transfer device 400 of the embodiment, the first rotating support 407 is adaptively rotatably mounted to the first clamp 404, and the second rotating support 408 is driven by the rotating drive 409, so that the flower basket 13 can be smoothly rotated. By using a rotating cylinder to drive the flower basket 13, the structure of the rotating drive can be simplified.

[0045] In the transfer device 400 of the embodiment, the first positioning portion 415 and the second positioning portion 416 are formed on the first rotating support 407 and the second rotating support 408, respectively, so that the flower basket 13 can be reliably clamped and positioned. By forming a rotation stopper 417 on at least one of the first rotating support 407 and the second rotating support 408, loosening of the flower basket 13 during the rotation process of the flower basket 13 can be suppressed, thereby improving the reliability of the rotation.

[0046] Although examples of the present embodiment have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present embodiment, and the scope of the present embodiment is defined by the claims and their equivalents.
