Description

Technical Field

[0001] This utility model relates to the field of solar cell component manufacturing technology, specifically to a Y-shaped tip tooth. Background Technology

[0002] In the production of solar silicon wafers, the thinness of the wafers makes them prone to cracks or scratches during processing or transfer, which can reduce the lifespan of the cells. Therefore, specialized clamps are needed to hold and transfer the wafers. For example, utility model patent application number CN202222498988.1 discloses a one-piece ceramic slab assembly, including a one-piece ceramic slab component. The one-piece ceramic slab component has longitudinal notches on both sides at one end. The one-piece ceramic slab component has a ceramic wafer body, an upper slab area, and a lower slab area. The upper slab area is connected to the upper part of one end of the ceramic wafer body, and the lower slab area is connected to the lower part of one end of the ceramic wafer body. The upper and lower slab areas do not contact each other. A transverse groove exists between the upper and lower slab areas, and an isolation element is provided within the transverse groove. This utility model can be used as a tooling fixture for producing solar silicon wafers, solving the problems of existing split ceramic wafer plates made by gluing and screwing. It eliminates the adverse effects of gluing and screwing on ceramic wafer plates. The integrated ceramic wafer plate has good firmness, high strength, will not form scratches on the silicon wafer surface, and has good wear resistance.

[0003] In the prior art, including the aforementioned patent, solar silicon wafers are clamped by upper and lower slab areas. However, the clamping area is relatively uniform during the clamping process. For larger silicon wafers, the relative weight of the wafers will increase, and their gravity will act on the smaller clamping surface. This will cause the silicon wafers to be subjected to uneven external forces, making them prone to cracks and thus affecting the service life of the silicon wafers. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned problems in the existing technology.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solution: a Y-shaped tip tooth, comprising:

[0031] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0032] like Figures 1-5 As shown, a Y-shaped tip tooth includes:

[0033] Main frame 1, with cover plate 2 provided on the main frame 1, forming an installation groove between cover plate 2 and main frame 1;

[0034] Top tooth 3 is set in the mounting groove, and the cross-section of top tooth 3 is Y-shaped;

[0035] Among them, a first patch 5 is provided on one side of the top tooth 3, and a second patch 6 is provided on the other side, forming a groove 73 between the first patch 5 and the second patch 6;

[0036] The fastener 4, the first patch 5 and the second patch 6 are fixed to the top tooth 3 by the fastener 4, and the top tooth 3 is fixed to the main frame 1 by the fastener 4.

[0037] Specifically, the main frame 1, cover plate 2, first patch 5, and second patch 6 are all made of ceramic material, which reduces the overall weight and prevents damage to the solar silicon wafers during clamping. The installation process is as follows: the top tooth 3 is first placed against the main frame 1, then the cover plate 2 is attached to the top tooth 3, and the cover plate 2 and the top tooth 3 are fixed to the main frame 1 by the fixing member 4. Then the first patch 5 and the second patch 6 are fixed to the top tooth 3 by the fixing member 4. There are at least two sets of first patch 5 and second patch 6, and the two sets are located on the extension 33, which increases the spacing between the two sets of patches to accommodate the clamping and conveying of silicon wafers of different sizes.

[0038] As a further embodiment provided by this utility model, the top tooth 3 is provided with a first through hole 31 and a second through hole 32, and the number of the first through hole 31 and the second through hole 32 is set to two. The fixing member 4 fixes the top tooth 3 to the main frame 1 through the first through hole 31, and the fixing member 4 fixes the first patch 5 and the second patch 6 to the top tooth 3 through the second through hole 32. The top tooth 3 is provided with an extension 33, and there are two second through holes 32, one of which is located on the extension 33, and the other is located at the symmetrical center of the top tooth 3 (e.g., Figure 3 As shown), this increases the contact area between the first patch 5 and the second patch 6 and the top tooth 3, thereby improving their support effect. The first through hole 31 consists of two sets that are aligned with the holes on the cover plate 2 and the holes on the second mounting platform 12, respectively, so that the cover plate 2 and the top tooth 3 can be fixed to the main frame 1 by the fastener 4.

[0039] As a further embodiment of this utility model, both the first patch 5 and the second patch 6 are provided with stepped holes 71. There is a gap between the fastener 4 and the stepped holes 71. An adhesive layer is provided in the gap. The adhesive layer improves the connection between the first patch 5 and the second patch 6 and the top tooth 3, and reduces the phenomenon of the first patch 5 and the second patch 6 becoming loose.

[0040] As a further embodiment provided by this utility model, the second patch 6 is longer than the first patch 5. During the clamping and transfer of the solar silicon wafer, the second patch 6 supports the silicon wafer from the bottom, while the first patch 5 restricts the silicon wafer. This allows for clamping and transport without damaging the silicon wafer. At the same time, the second patch 6 has a larger bonding area, which further improves the support effect on the silicon wafer.

[0041] As a further embodiment of this utility model, the main frame 1 is provided with a first mounting platform 11 and a second mounting platform 12. The first mounting platform 11 is higher than the second mounting platform 12. The top tooth 3 abuts against the second mounting platform 12, while the cover plate 2 abuts against the first mounting platform 11 to fix the top tooth 3. The cover plate 2 is used to fix the top tooth 3. The cover plate 2 has a total of three holes, two of which are used to fix the top tooth 3, and the remaining one is used to connect and fix the cover plate 2 to the main frame 1. The three holes improve the firmness between the cover plate 2 and the main frame 1, and also improve the support effect on the top tooth 3.

[0042] As a further embodiment provided in this utility model, both the first patch 5 and the second patch 6 are provided with inclined heads 72 whose inclined surfaces face the clamping groove 73, such as Figure 4 As shown, the two tilting heads 72 can better fit the bottom of the solar silicon wafer when loading materials, improving loading efficiency.

[0043] As a further embodiment of this utility model, the fastener 4 includes a support body 41 and a connecting post 42 disposed on the support body 41. The support body 41 is provided with a second adhesive portion 44, and the connecting post 42 is provided with a first adhesive portion 43. After the connecting post 42 is assembled with the support body 41, a portion of it will protrude, which is a polishing portion 421. It is polished by an external polishing machine to make the connecting portion flush with the first patch 5. The first adhesive portion 43 and the second adhesive portion 44 are both places where glue is filled. The combination of the glue and the fastener 4 improves the fixing effect on the first patch 5 and the second patch 6.

[0044] As a further embodiment of this utility model, a tapered groove 412 is provided on the support body 41, and an adhesive outlet hole 411 is provided on the tapered groove 412. A first flow channel 422 and a second flow channel 423 are arranged in a circumferential array on the connecting column 42. The first flow channel 422 is connected to the adhesive outlet hole 411 through the second flow channel 423. After the connecting column 42 and the support body 41 are fully connected, the connecting column 42 can be positioned with the support body 41 facing downwards, thereby facilitating the connection between the connecting column 42 and the stepped hole 71. The gaps between them are filled with colloid. Under the action of gravity, the colloid flows from top to bottom from the first flow channel 422 to the second flow channel 423, and then flows from the second flow channel 423 and the outlet to the conical groove 412 for filling. This makes the colloid conical, and the conical groove 412 is located at the symmetrical center of the top tooth 3. This improves the clamping and fixing effect of the fastener 4 on the first patch 5 and the second patch 6. At the same time, the gap between the support body 41 and the stepped hole 71 is filled with colloid.

[0045] As a further embodiment of this utility model, the connecting post 42 includes a guide post 426. The guide post 426 is provided with an inclined portion 425 and a locking portion 424 connected to each other. The locking portion 424 abuts against the support body 41. The guide post 426 plays a guiding role, so that the connecting post 42 can better enter the support body 41 for connection and fixation. During the connection and fixation process of the connecting post 42, the inclined portion 425 on the guide post 426 will contact the inner wall of the support body 41 in advance. At this time, the inclined portion 425 and the locking portion 424 will be squeezed and retracted into the second flow channel 423. When the connecting post 42 is fully inserted into the support body 41, the locking portion 424 will unfold and abut against the support body 41, thereby completing the connection and fixation of the fastener 4.

[0046] As a further embodiment provided by this utility model, the top tooth 3 is an aluminum sheet. The use of ceramic materials can be reduced by the intermediate aluminum sheet without affecting the overall product performance requirements. At the same time, the aluminum sheet has greater strength and rigidity, and is not easily deformed under greater external force. In addition, the aluminum sheet is lighter, which reduces the overall weight of the fixture.

[0047] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0048] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
