Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic solar cell manufacturing technology, and in particular relates to a device for increasing the number of printing cycles of the main grid screen for solar cells. Background Technology

[0002] With the development of high-efficiency crystalline silicon solar cell technology, the market demand for cell conversion efficiency is constantly increasing, and the process technology is updated and iterated rapidly. N-type cell technology has emerged as a result. N-type cells have advantages such as high conversion efficiency, anti-attenuation, low temperature coefficient, and high bifaciality. However, the non-silicon cost of N-type cells is relatively high, mainly in the cost of silver consumption and printing auxiliary materials.

[0003] The screen printing plate uses 430 mesh and PI film, which has a wear resistance far superior to the original emulsion film. While increasing wear resistance, it also increases the number of screen printing cycles. However, this results in decreased puncture resistance and frequent ink leakage, limiting the number of printing cycles and causing inconsistent product quality. Therefore, we designed a device to increase the number of printing cycles for the battery main grid screen. By attaching a layer of ultra-thin wear-resistant tape to the printing area, the puncture resistance of the mesh is improved without affecting the printing quality. Furthermore, the extended ends of multiple tapes can be cut off as a whole, reducing processing time. Utility Model Content

[0004] The purpose of this invention is to provide a device for increasing the number of printing cycles for a battery main grid screen. This device improves the tear resistance of the screen fabric by attaching a layer of ultra-thin, wear-resistant tape to the printing area without affecting the printing quality. It also has the advantage of being able to cut off the extended ends of multiple tapes as a whole, reducing processing time, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for increasing the number of printing cycles of a battery main grid screen includes a base box. Multiple support ribs are fixedly connected to the bottom of the inner cavity of the base box. Multiple side cavities are opened on both sides of the top of the base box. Multiple limiting blocks are fixedly connected to both sides of the inner cavity of the base box. A 430 mesh is placed in the inner cavity of the base box. Multiple thin, wear-resistant adhesive tapes are adhered to the top of the 430 mesh. Both ends of the thin, wear-resistant adhesive tapes extend into the inner cavity of the side cavities. A PI film is adhered to the top of the thin, wear-resistant adhesive tapes. A top cover is movably connected to the surface of the base box. Blades are installed on both sides of the top of the inner cavity of the top cover.

[0006] Preferably, the top of the base box has grooves on both sides and the top of the limiting block for inserting the blade.

[0007] Preferably, the top of the limiting block is provided with an arc-shaped surface, and the two sides of the 430 mesh are respectively adapted to the arc-shaped surface.

[0008] Preferably, the rear ends of both sides of the base box are provided with rotating holes, and the inner sides of the upper cover cavity are fixedly connected with shaft pins that rotate in the rotating hole cavity.

This utility model places 430 mesh in the inner cavity of the base box, then pastes thin abrasion-resistant tape as needed and extends it to the inner cavity of the side cavity, then places PI film on the top, and then flips the top cover over the surface of the base box. Two blades in the inner cavity of the top cover cut multiple thin abrasion-resistant tapes, thereby achieving the purpose of improving the tear resistance of the mesh without affecting the printing quality by pasting a layer of ultra-thin abrasion-resistant tape in the printing area, and also cutting off the extended ends of multiple tapes as a whole, reducing processing time.

[0020] In the following description, embodiments of the battery main grid printing increase device of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a device for increasing the number of printing cycles for a battery main grid screen according to an embodiment of the present invention. It includes a base box 1, with multiple supporting ribs 2 fixedly connected to the bottom of the inner cavity of the base box 1. Multiple side cavities 3 are equally spaced on both sides of the top of the base box 1. Multiple limiting blocks 4 are fixedly connected to both sides of the inner cavity of the base box 1. A 430 mesh 5 is placed inside the inner cavity of the base box 1. An arc-shaped surface 11 is provided on the top of each limiting block 4. Both sides of the 430 mesh 5 are adapted to the arc-shaped surface 11. Through the arc-shaped surface 11, the 430 mesh 5 contacts the arc-shaped surface 11 on the limiting block 4 during placement inside the inner cavity of the base box 1. The arc-shaped surface 11 can guide and limit the 430 mesh 5, so that the 430 mesh 5 can stably enter the inner cavity of the base box 1. Multiple thin wear-resistant tapes 6 are bonded to the top of the 430 mesh 5. Both ends of the thin wear-resistant tapes 6 extend into the inner cavity of the side cavity 3. A PI film 7 is bonded to the top of the thin wear-resistant tapes 6. The surface of the base box 1 is movably connected to the top cover 8. Rotating holes 13 are opened at the rear ends of both sides of the base box 1. The inner cavities of the top cover 8 are fixedly connected to the shaft pins 12 that rotate in the inner cavity of the rotating holes 13. Blades 9 are installed on both sides of the top of the inner cavity of the top cover 8. The top sides of the base box 1 and the top of the limiting block 4 are provided with cutting grooves 10 for the blades 9 to be inserted.

[0022] Working principle: When using this utility model, by placing the 430 mesh 5 in the inner cavity of the base box 1, the arc surface 11 on the limiting block 4 can ensure that the 430 mesh 5 is accurately located deep in the inner cavity of the base box 1 and is supported by multiple support ribs 2. Then, as needed, the thin wear-resistant tape 6 is pasted and extended to the inner cavity of the side cavity 3. Then, the PI film 7 is glued to the upper part of the 430 mesh 5 through multiple thin wear-resistant tapes 6. Then, the top cover 8 is flipped onto the surface of the base box 1. The top cover 8 rotates in the inner cavity of the rotating hole 13 through the shaft pin 12. The two blades 9 in the inner cavity of the top cover 8 will enter the inner cavity of the cutting groove 10, and the blades 9 will cut the multiple thin wear-resistant tapes 6.

[0023] In summary, this battery main grid printing increase device achieves its purpose by placing a 430 mesh 5 inside the base box 1, then attaching and extending a thin abrasion-resistant tape 6 to the inner cavity of the side cavity 3 as needed, placing a PI film 7 on top, and then flipping the top cover 8 over the surface of the base box 1. The two blades 9 inside the top cover 8 cut multiple thin abrasion-resistant tapes 6, thereby achieving the goal of improving the tear resistance of the mesh without affecting the printing quality by attaching a layer of ultra-thin abrasion-resistant tape to the printing area, and also cutting off the extended ends of multiple tapes as a whole, thus reducing processing time.
