Description

Technical Field

[0001] The present application belongs to the technical field of solar cells, and in particular relates to a wafer fixing device. Background Art

[0002] At present, when other chain transmissions use belt transmission to load solar cell silicon wafers into wafer boxes, due to the production requirements of fast speed and the requirement that the solar cell silicon wafers must be loaded at the bottom of the wet wafer box, under the existing belt transmission accuracy conditions, the bottom edge of the cell silicon wafer will hit the side rod of the wet wafer box with great force, causing cell fragments or other defects.

[0003] Therefore, in the original design, the wafer carrier box fixing device had no buffer components, and the solar cell silicon wafers were transferred to the wet wafer carrier box by the lateral movement of the belt on site. Due to the fast transmission speed, the solar cell silicon wafers generated a large impact force with the bottom edge of the side rod of the wafer carrier box after they were in place, causing damage to the solar cell silicon wafers and forming broken edges and gaps.

At this time, the second profile 5 moves with the movement of the first profile 4, so the elastic buffer component 3 can move with the movement of the carrier box clamping structure 1, and at the same time, the installation position of the elastic buffer component 3 cannot conflict with the normal up and down movement of the carrier box clamping structure 1;

[0055] Meanwhile, a plurality of holes 12 are provided on the first bracket 6 and the second bracket 7 , and the holes 12 are used for fixing screws.

[0062] In order to prevent the second bracket 7 from colliding or interfering with the first side rod 8, the distance between the second bracket 7 and the first side rod 8 is greater than the distance between the second profile 5 and the first side rod 8, that is, the second profile 5 and the first side rod 8 also retain a distance; a distance is retained between the second profile 5 and the first base plate 10 and the second base plate 9, so that the second profile 5 is suspended, preventing friction or interference when the second profile 5 moves up and down with the wafer carrier box 2, thereby improving the safety and stability of the elastic buffer component 3.

[0063] Among them, the first side rod 8 is arranged on the first side 30 close to the first bottom plate, and the first side 30 of the first bottom plate is on the opposite side of the wafer carrier 2 away from the solar cell silicon wafer feeding port, that is, the first side rod 8 is arranged close to the bottom of the wafer carrier 2, and the solar cell silicon wafers are transmitted to the wet wafer carrier 2 by the lateral movement of the belt.

[0071] Preferably, the distance between the second bracket 7 and the first end 27 of the second profile is equal to the distance between the second bracket 7 and the second end 28 of the second profile.

[0072] The second bracket 7 is arranged in the middle of the second profile 5, so that when the solar cell silicon wafer contacts the rubber gasket, the force exerted on the second profile 5 is more uniform, and the second profile 5 is not easily deformed or changed in position, thereby improving the buffering effect.

[0073] Preferably, the rubber gasket is made of polyoxymethylene, the thickness of the rubber gasket is 3-4 mm, and the length and width of the rubber gasket can be aligned with the length and width of the raised component.

[0074] Specifically, the material of the adhesive gasket cannot be a hard material, otherwise the solar panel silicon wafer will still form a large impact with the adhesive gasket after contacting the adhesive gasket, causing the silicon wafer to collapse, gaps and other undesirable phenomena.

[0075] Preferably, the film carrier box clamping structure 1 further includes a first clamping plate 13, a second clamping plate 14, a first mounting plate 15, a second mounting plate 16, and a first reinforcing plate 17.

[0076] The first clamping plate 13 is disposed on the first side 23 of the first profile, and the second clamping plate 14 is disposed on the second side 24 of the first profile. The first clamping plate 13 and the second clamping plate 14 are used to clamp the first profile 4;

The first profile 4 is fixedly installed and moves on the lifting module 20. At this time, the second profile 5 moves with the movement of the first profile 4, that is, the wafer box clamping structure 1 is lifted and moved on the lifting module 20 to the end of the conveyor belt and fixed, and the solar cell silicon wafer is transmitted to the wet wafer box 2 by the lateral movement of the belt. When the solar cell silicon wafer is loaded into the bottom of the wafer box 2, the solar cell silicon wafer contacts the rubber gasket on the second profile 5, which plays a buffering role, ensuring the rapid batch production of solar cell silicon wafers while greatly reducing the phenomenon of silicon wafer edge collapse and fragmentation caused by the cell hitting the side rod of the wafer box 2.

[0087] During the research and development stage of the technical solution of the present application, the installation method of the elastic buffer component 3 is first determined by the on-site wet wafer box 2 fixture, and the on-site tests are carried out by installing a block at the end of the transmission tongue and by installing the elastic buffer component 3 with a profile and a rubber gasket in the wet wafer box 2 fixture. Finally, the test conclusion is that the silicon wafer fragmentation rate is lower by installing the elastic buffer component 3 with a profile and a rubber gasket in the wet wafer box 2 fixture, and the buffering effect is better.

[0090] The technical solution of the present application ensures that the solar cell wafers are loaded into the deepest part of the wet wafer box at a high speed and accurately by adding an elastic buffer component composed of a profile and a flexible rubber pad to the wet wafer box fixing device, while reducing the impact force of the solar cell silicon wafers when they are transferred into the wafer box, so that they no longer rigidly contact the bottom edge of the wafer box and cause damage to the solar cell wafers.
