Problems solved by technology
[0002] Flexible thin-film solar cells, including flexible silicon thin-film solar cells, flexible CIGS solar cells, polymer substrate cells, etc., in the large-area production process, the grid electrode preparation on the front of the cell is very important. In actual production, silver wires need to be arranged On the surface of the battery, keep the spacing consistent, stretch the silver wires, and then use a laminator to solidify them. The traditional process is that the spacing of the silver wires can only be controlled by visual inspection or simple calibration. It needs to move the battery many times. The straightness of the line is very poor, and the flexible substrate is bent during the transfer process, the battery is damaged, and the conductive silver line will become crooked and cannot be fixed, which seriously affects the performance of the flexible substrate battery
Therefore, the yield rate in actual production is not high, how to improve production efficiency, reduce costs, and improve product yield rate is a key issue

Embodiment 1
[0016] 1) Place the device flat on the test bench, and gently lay the finished flexible battery on the metal plate with suction function. Through the metal plate with through holes, the vacuum adsorption device (such as a vacuum pump) will Adhere the battery tightly to the metal plate.
[0017] 2) By loosening the knobs of the screw on both sides of the grid wire winding device, move the metal rod with the positioning column to find a suitable angle with the horizontal position, and then tighten the screw knob to fix the metal rod.
[0018] 3) Glue polyimide tape on the left and right sides of the battery, on the one hand to prevent short circuits, and on the other hand to adhere to the silver wires that will be packaged next.
[0019] 4) Pull the silver wire with a thread and fix it at the first card slot on the left. The position of the lower end of the first card slot on the left is parallel to the upper end of the second card slot on the right, and then wrap it left and ri...

The invention relates to an apparatus and a packaging method for packaging a grid line electrode of a flexible solar battery conveniently. The apparatus consists of a grid line winding apparatus, an absorption sheet functional metal plate and a constant temperature heater; grid line fixing and paralleling can be completed on the apparatus in one step, and then packaging and laminating can be performed; in addition, it is ensured that the spacings of the grid lines are consistent and the grid lines are stretched linearly; by rotating screw rotary knobs on the two sides and by enabling the screwrotary knobs to be rotated out of clamping grooves, the angles of metal rods fixed with small cylinders of a certain number can be adjusted, wherein the maximum position refers to that an angle of 45degrees is formed between the metal rods and the horizontally-placed metal plate; and next, the screw rotary knobs are screwed tightly, and the two rows of the metal rods fixed with the small cylinders can be fixed through extrusion and fixation.
