Since a large amount of surface area of the cell is occupied by the main grid lines, the light receiving area of the cell is greatly reduced, and finally the photoelectric conversion efficiency of the cell is limited. Therefore, the no main grid (0BB) cell is widely used due to its high power generation efficiency.

The film pasting device is configured to lay an (i+1)th back surface adhesive film to a first laying position and lay an (i+1)th welding strip group to the first laying position and a second laying position. The cell laying device is configured to lay an (i+1)th cell to the first laying position, so that the (i+1)th back surface adhesive film adheres the latter half of the (i+1)th welding strip group to the back surface of the (i+1)th cell. The film pasting device is further configured to lay an ith front surface adhesive film to the second laying position, so that the ith front surface adhesive film adheres the former half of the (i+1)th welding strip group to the front surface of the ith cell. The stringing conveying device is configured to step a predetermined distance to the next process, so as to leave the first laying position.

In this invention, the width adjustment component allows the operator to manually operate the first hand crank to rotate the connecting shaft and the first lead screw. Under the action of multiple linkage units, the lead screw sleeve and multiple rectangular sliding seats drive multiple limit sliders, connecting sleeves, and limiting guide wheels to move synchronously and equidistantly on the outer periphery of the first lead screw.

This moves the clamped and fixed battery welding strip. At this time, the vertical plate will transport the water inside the main liquid bladder to the sub-liquid bladder through the connecting plate, causing the sub-liquid bladder to expand and drive the horizontal plate, connecting block, U-shaped seat, and limiting guide wheel to move slightly downward. During the process of the drive motor driving the second lead screw to rotate in the opposite direction to reset the limiting guide wheel, the limiting guide wheel presses the battery electrode and battery welding strip during the initial welding and solidification process, thereby effectively eliminating air bubbles, enhancing bonding force, significantly improving welding quality and consistency, and thus effectively improving the welding effect of the product during use.

[0017] 3. In this invention, the cutting component allows the sliding seat and cutting blade to move upward via an electric push rod to cut the installed battery welding strip before the guide wheel resets. After cutting, the cleaning block cleans the adhesive residue adhering to the surface of the cutting blade during the reset process, reducing the amount of adhesive residue adhering to the cutting blade surface after prolonged use, thus preventing any impact on the cutting effect and welding quality of the battery welding strip. An external liquid extraction device removes the adhesive residue cleaned by the cleaning block. The operator can manually rotate the second hand crank to rotate the pin shaft and the limiting block 90 degrees, allowing for disassembly and replacement of the cleaning block, thereby effectively ensuring the product's portability.

After the limiting guide roller 807 and fixed roller 815 on one side have completed the laying of the battery welding strip, the vertical plate 703 will then move against the connecting plate 70. 4. The main liquid bladder 705 and the first spring 706 are squeezed together, and the water inside the main liquid bladder 705 is transported to the auxiliary liquid bladder 708 through the infusion tube 707.

During the process of the drive motor 702 driving the second lead screw to rotate in the opposite direction to reset the limiting guide wheel 807, the trigger button on the vertical plate 703 will release the opening state of the switch valve on the infusion tube 707 to maintain the slight movement of the limiting guide wheel 807.

[0026] Specific implementation: before the limiting guide wheel 807 is reset, the sliding seat and the cutting knife 902 can be moved upward by the electric push rod, the installed battery welding strip is cut by the cutting knife 902, and then the limiting guide wheel 807 is reset. When the limiting guide wheel 807 is about to move to the position of the cutting knife 902, the sliding seat and the cutting knife 902 are moved downward by the electric push rod. In this process, the external air extraction device extracts the gas in the pipe sleeve 801 through the air extraction pipe 809 and the sealing slip ring 808. The pipe sleeve 801 is adsorbed through the air extraction cylinder 811, the air extraction channel in the connecting sleeve 806, the cavity in the limiting guide wheel 807 and the plurality of air extraction openings, and the driving unit 812 drives the annular pipe sleeve 813, the arc-shaped frame 814 and the fixed roller 815 to reset. The fixed roller 815 is fixed again by the lifting unit. During the movement of the cutting knife 902, the cleaning block 907 can clean the glue adhered to the surface of the cutting knife 902, so as to reduce the adhesion of a large amount of glue to the surface of the cutting knife 902 after a long time of use, thereby preventing the cutting effect and welding quality of the battery welding strip from being affected. The external liquid extraction device extracts the glue cleaned by the cleaning block 907.
