The component line is also called the packaging line, the packaging is a key step in the production of solar cells, there is no good packaging process, and no good battery can produce a good module board. The encapsulation of the battery not only guarantees the life of the battery, but also enhances the resistance of the battery. The high quality and longevity of the product is the key to customer satisfaction, so the packaging quality of the component board is very important.
Process:
1, battery testing - 2, front welding - inspection - 3, back series - inspection - 4, laying (glass cleaning, material cutting, glass pretreatment, laying) - 5, laminating - 6, depiling (edge removal, cleaning) - 7, frame (glue, corner mounting key, punching, framing, scrubbing residual glue) - 8, welding junction box - 9, high voltage test - 10, component test - appearance inspection - 11, packaging storage
How efficient and high component life is guaranteed:
1. High conversion efficiency, high quality battery; 2. High-quality raw materials, such as: EVA with high crosslinking degree, encapsulant with high bond strength (neutral silicone resin glue), tempered glass with high light transmittance and high strength; 3. Reasonable packaging process; 4. Rigorous work style of employees;
Because the solar cell is a high-tech product, some details in the production process, some inconspicuous problems such as should wear gloves without wearing, should be uniformly brushed reagents and scribbled, etc. are the enemy of product quality, so in addition to formulating a reasonable production process, the seriousness and rigor of employees is very important.
Introduction to the solar cell assembly process: Process Introduction: Here is only a brief introduction to the role of the process, to give everyone a perceptual understanding.
1, battery test: due to the randomness of the battery production conditions, the battery performance produced is not the same, so in order to effectively combine the batteries with consistent or similar performance, it should be classified according to its performance parameters; battery test is classified by testing the size of the output parameters (current and voltage) of the battery. To improve the utilization of the battery, make a qualified quality battery module. 2, front welding: is the pool belt welded to the battery front (negative) of the main grid line, the combiner belt for tin plated copper strip, we use the welding machine can be welded in the form of multiple points on the main grid line. The heat source used for welding is an infrared lamp (using the thermal effect of infrared rays). The length of the welding strip is about 2 times the length of the battery side. The extra electrode is connected to the back electrode of the rear cell when the back is welded. 3, the back of the string: the back of the welding is to string 36 cells together to form a component string, we are c
