Description

Technical Field

[0001] This utility model relates to the field of solar cells, specifically a cell half-cell assembly and separation device. Background Technology

[0002] Overlapping and splicing two solar cells is called lamination, while separating the overlapped cells is called separation. Traditional lamination and separation processes involve transferring the cells between baskets and graphite boats. Typically, two baskets are used, with a graphite boat placed on one side of each basket. A transfer mechanism is positioned between the baskets and the graphite boat. The silicon wafers in the two baskets are placed with their front and back sides reversed. The transfer mechanism overlaps the wafers from the two baskets and places them into the graphite boat to complete the lamination. However, because the dimensions of the graphite boat and the basket are usually inconsistent (the graphite boat is typically half the length of the basket), existing mechanisms can only extract half of the silicon wafers from one basket at a time, reducing work efficiency.

[0003] Therefore, it is necessary to provide a battery half-cell assembling and splitting device. Summary of the Invention

[0004] This utility model provides a battery half-cell assembly and separation device, which effectively solves the problem of low efficiency in existing half-cell assembly and separation processes.

[0005] The technical solution adopted in this utility model is:

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the first embodiment provided in this application is a battery half-cell assembling and separating device, including two basket mechanisms 1 arranged along the X direction, two graphite boat mechanisms 2 respectively disposed on opposite sides of the two basket mechanisms 1, and a cell transfer mechanism 3. The cell transfer mechanism 3 includes a frame 31 extending along the X direction, a first guide rail 32 and a rack 33 disposed along the Y direction on the frame 31, and a first cell transfer assembly 34 and a second cell transfer assembly 35 slidably disposed on the first guide rail 32. Both the first cell transfer assembly 34 and the second cell transfer assembly 35 include a slide rail slidably disposed on the first guide rail 32. The components include a plate 341, a motor gear assembly 342 that meshes with a rack 33 on the slide plate 341, a second guide rail 343 that is mounted on the slide plate 341 along the Z-axis, a lifting frame 344 that is slidably mounted on the second guide rail 343, a fourth linear module 36 that is fixedly mounted on the slide plate 341 for driving the lifting frame 344 to rise and fall, and two suction cup assemblies 3453 that are mounted on the lifting frame 344 along the Y-axis. The suction cup assemblies 3453 of the first wafer shifting assembly 34 are adsorbed from the left side of the silicon wafer, and the suction cup assemblies 3453 of the second wafer shifting assembly 35 are adsorbed from the right side of the silicon wafer.

[0024] The silicon wafers in the two flower basket mechanisms 1 are arranged with their front and back sides reversed.

[0025] In actual use, the first wafer transfer assembly 34 adsorbs and lifts the silicon wafer from the left side of one of the basket mechanisms 1, while the second wafer transfer assembly adsorbs and lifts the silicon wafer from the right side of the other basket mechanism 1. Then, the first wafer transfer assembly 34 and the second wafer transfer assembly 35 align the adsorbed silicon wafers end to end, achieving wafer bonding and placing them in one of the graphite boat mechanisms 2. Subsequently, the first wafer transfer assembly 34 and the second wafer transfer assembly 35 adsorb and separate the bonded silicon wafers in the other graphite boat mechanism 2 and transfer them to the empty basket mechanism 1. The first wafer transfer assembly 34 and the second wafer transfer assembly 35 operate on the same principle: the engagement and disengagement of the motor gear assembly 342 on the rack 33 enables the slide plate 341 to move in the X direction, driving the lifting frame 344 and the suction cup assembly 3453 to move synchronously.

[0026] In the above design, by using two suction cups 3453 components 345 to simultaneously pick up wafers from a basket 15, it is possible to quickly assemble and separate silicon wafers, thereby improving work efficiency.

[0027] Specifically: such as Figure 6 and Figure 5As shown, the graphite boat mechanism 2 includes two graphite boats 21 arranged along the Y direction, two first lifting drive mechanisms 22 that drive the graphite boats 21 to rise and fall respectively, and a first linear module 23 that drives the two first lifting drive mechanisms 22 to move along the X direction. The suction cup 3453 assembly 345 includes a lead screw module 3451 arranged along the Y direction on the lifting frame 344, a moving frame 3452 arranged on the lead screw module 3451, and a plurality of suction cups 3453 arranged along the Y direction on the moving frame 3452. The suction cups 3453 of the first wafer shifting assembly 34 adsorb from the left side of the silicon wafer, and the suction cups 3453 assembly 345 of the second wafer shifting assembly 35 adsorb from the right side of the silicon wafer.

[0028] In actual use, the graphite boat 21 is raised and lowered by the first lifting drive mechanism 22, and the first linear module 23 drives the first lifting mechanism to move along the X direction, causing the graphite boat 21 to move synchronously along the X direction. The lead screw modules 3451 of the two suction cup 3453 assemblies 345 respectively drive the corresponding moving frames 3452 to move along the Y direction, causing the moving frames 3452 to move the suction cups 3453 synchronously, thereby realizing the closing or opening of the two suction cup 3453 assemblies 345. When the two suction cup 3453 assemblies 345 are closed, they can extend into the same basket 15 to adsorb and extract all the half-wafers of silicon wafers in the basket 15 at once. When the two suction cup 3453 assemblies 345 are opened, they correspond to the two graphite boats 21 in the same graphite boat mechanism 2.

[0029] In the above design, the design of the graphite boat mechanism 2 and the suction cup 3453 component 345 facilitates the transfer of half of the silicon wafer in the same flower basket 15 component to two different graphite boats 21 for lamination.

[0030] Specifically: such as Figure 4 As shown, the flower basket mechanism 1 includes a second linear module 11 arranged along the Y direction, a mounting plate 12 arranged at the output end of the second linear module 11, a third linear module 13 arranged along the Z axis on the mounting plate 12, a lifting plate 14 arranged at the output end of the third linear module 13, and two flower baskets 15 arranged on the lifting plate 14, the two flower baskets 15 being arranged along the X direction.

[0031] In actual use, the No. 2 linear module 11 drives the mounting plate 12 to drive the No. 3 linear module 13, as well as the lifting plate 14 and the flower basket 15 to move synchronously along the Y direction. The No. 3 linear module 13 drives the lifting plate 14 and the two flower baskets 15 to rise and fall synchronously.

[0032] In the above design, the structural design and specific implementation of the flower basket mechanism 1 facilitate the lifting and horizontal movement of the flower basket 15, ensuring that the flower basket 15 can be moved to the discharge or receiving position.

[0033] Specifically: such as Figure 6 As shown, the graphite boat 21 is provided with two rows of feeding troughs 210.

[0034] In actual use, during the wafer assembly process, the two rows of feeding troughs 210 receive the assembled silicon wafers in two separate operations. During the wafer separation process, the wafer transfer mechanism 3 removes the entire silicon wafer from the two rows of feeding troughs 210 in two separate operations.

[0035] In the above design, the structural design and specific implementation of the graphite boat 21 facilitate the placement of the silicon wafer.

[0036] Specifically, the motor gear assembly 342 shown includes a motor mounted on a slide plate 341 and a gear mounted on the motor output shaft, the gear meshing with a spur rack 33.

[0037] In actual use, the motor drives the gear to rotate, and the meshing of the gear with the rack 33 drives the slide plate 341 to move along the first guide rail 32.

[0038] In the above design, the structural design and specific implementation of the motor gear assembly 342 can effectively drive the first shifting plate assembly 34.

[0039] Specifically: such as Figure 1 and Figure 7 As shown, the wafer shifting mechanism 3 and the graphite boat mechanism 2 are also provided with a correction mechanism 4. The correction mechanism 4 includes a crossbeam disposed on the frame 31, a first correction component 41 disposed on the crossbeam for correcting the silicon wafers in the basket mechanism 1, and a second correction component 42 disposed on the crossbeam for correcting the silicon wafers in the graphite boat mechanism 2.

[0040] In actual use, the first correction component 41 is used to correct the half silicon wafer in the flower basket 15, and the second correction component 42 is used to correct the whole silicon wafer in the graphite boat 21.

[0041] In the above design, the structural design and specific implementation of the alignment mechanism 4 facilitate the alignment of the silicon wafer, ensuring that the silicon wafer can be accurately placed in the predetermined position after transfer.

[0042] Specifically: the first correction component 41 includes two first cantilever arms slidably disposed on the crossbeam and a first belt transmission component disposed on the crossbeam for driving the two first cantilever arms to move relative to each other; the second correction component 42 includes two second cantilever arms slidably disposed on the crossbeam and a second belt transmission component disposed on the crossbeam for driving the two second cantilever arms to move relative to each other.

[0043] In actual use, the first belt conveyor drives the two first cantilever arms to move towards each other, so that the two first cantilever arms respectively align the half of the silicon wafer from both sides. The second belt conveyor drives the two second cantilever arms to move towards each other, so that the two second cantilever arms respectively align the whole silicon wafer from both sides.

[0044] In the above design, the structural design and specific implementation of the first correction component 41 and the second correction component 42 facilitate the stable and rapid correction of the silicon wafer.

[0045] The second embodiment provided in this application is a battery half-cell assembling and separating device, including two basket mechanisms 1 arranged along the X direction, two graphite boat mechanisms 2 respectively disposed on opposite sides of the two basket mechanisms 1, and a cell transfer mechanism 3. The cell transfer mechanism 3 includes a frame 31 extending along the X direction, a first guide rail 32 and a rack 33 disposed along the Y direction on the frame 31, and a first cell transfer assembly 34 and a second cell transfer assembly 35 slidably disposed on the first guide rail 32. The first cell transfer assembly 34 and the second cell transfer assembly 35 both include a sliding plate 3 slidably disposed on the first guide rail 32. 41. A motor gear assembly 342 that meshes with a rack 33 on a slide plate 341; a second guide rail 343 that is mounted on the slide plate 341 along the Z-axis; a lifting frame 344 that is slidably mounted on the second guide rail 343; a fourth linear module 36 that is fixedly mounted on the slide plate 341 for driving the lifting frame 344 to rise and fall; and two suction cup assemblies 3453 that are mounted on the lifting frame 344 along the Y-axis. The suction cup assemblies 3453 of the first wafer shifting assembly 34 adsorb from the left side of the silicon wafer, and the suction cup assemblies 3453 of the second wafer shifting assembly 35 adsorb from the right side of the silicon wafer. The graphite boat mechanism 2 includes two graphite boats 21 arranged along the Y direction, two first lifting drive mechanisms 22 that drive the graphite boats 21 to rise and fall respectively, and a first linear module 23 that drives the two first lifting drive mechanisms 22 to move along the X direction. The suction cup 3453 assembly 345 includes a lead screw module 3451 arranged along the Y direction on the lifting frame 344, a moving frame 3452 arranged on the lead screw module 3451, and a plurality of suction cups 3453 arranged along the Y direction on the moving frame 3452. The suction cups 3453 of the first wafer shifting assembly 34 adsorb from the left side of the silicon wafer, and the suction cups 3453 assembly 345 of the second wafer shifting assembly 35 adsorb from the right side of the silicon wafer. The basket mechanism 1 includes a second linear module 11 arranged along the Y direction, a mounting plate 12 disposed at the output end of the second linear module 11, a third linear module 13 disposed along the Z axis on the mounting plate 12, a lifting plate 14 disposed at the output end of the third linear module 13, and two baskets 15 disposed on the lifting plate 14, the two baskets 15 being arranged along the X direction. The graphite boat 21 is provided with two rows of feeding troughs 210. The motor gear assembly 342 shown includes a motor disposed on a slide plate 341 and a gear disposed on the output shaft of the motor, the gear meshing with a spur rack 33. The wafer shifting mechanism 3 and the graphite boat mechanism 2 are also provided with a straightening mechanism 4, the straightening mechanism 4 including a crossbeam disposed on a frame 31, a first straightening component 41 disposed on the crossbeam for straightening the silicon wafers in the basket mechanism 1, and a second straightening component 42 for straightening the silicon wafers in the graphite boat mechanism 2.The first correction component 41 includes two first cantilever arms slidably mounted on the crossbeam and a first belt transmission component mounted on the crossbeam for driving the two first cantilever arms to move relative to each other. The second correction component 42 includes two second cantilever arms slidably mounted on the crossbeam and a second belt transmission component mounted on the crossbeam for driving the two second cantilever arms to move relative to each other.

[0046] The actual wafer assembly process is as follows: The first alignment component 41 aligns the half silicon wafers in the basket 15. The two lead screw modules 3451, belonging to the two suction cup 3453 components 345 respectively, drive the suction cups 3453 to move towards each other, so that the two suction cup 3453 components 345 close together. This allows the two suction cup 3453 components 345 of the first wafer shifting component 34 to simultaneously extend into one of the baskets 15 of one of the basket mechanisms 1 and adsorb all the half silicon wafers in the basket 15 from the left side. The two suction cup 3453 components 345 of the second wafer shifting component 35 can simultaneously extend into the basket 15 of the other basket mechanism 1 and adsorb all the half silicon wafers in the basket 15 from the right side. Subsequently, the lifting frame 344, driven by the fourth linear module 36, raises the suction cup 3453 assembly 345 from the basket 15. Then, the two lead screw modules 3451, belonging to the two suction cup 3453 assemblies 345 respectively, drive the respective suction cups 3453 to move in opposite directions, causing the two suction cup 3453 assemblies 345 to separate. At this time, the distance between the two suction cup 3453 assemblies 345 is equal to the distance between the two graphite boats 21 in the same graphite boat mechanism 2. Then, the first wafer shifting assembly 34 and the second wafer shifting assembly 35 close together, so that the two suction cup 3453 assemblies 345 in the first wafer shifting assembly 34 are staggered and aligned with the respective half-wafers of silicon adsorbed by the two suction cup 3453 assemblies 345 in the second wafer shifting assembly 35. Then, the lead screw modules 3451 of each suction cup 3453 assembly 345 drive the corresponding suction cup 3453 to move, so that the staggered and aligned adjacent half-wafers of silicon adsorbed are closed together to form a whole silicon wafer. Then, the first lifting drive mechanism 22 and the first linear module 23 drive the two graphite boats 21 to move to the predetermined wafer receiving position. Subsequently, the fourth linear modules 36 belonging to the first wafer shifting assembly 34 and the second wafer shifting assembly 35 synchronously drive the respective suction cup 3453 assemblies 345 to move downward, so that the entire silicon wafer is placed in the graphite boat 21. The actual wafer separation process is the reverse of the actual wafer assembly process.

[0047] The above design enables rapid assembly and separation of half-wafers, improving the efficiency of assembly and separation.

[0048] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model.
