The equipment involved in the manufacturing process of photovoltaic modules mainly includes: automatic sorting machine, stringing machine, busbar welding machine, laminating machine, edge trimming machine, EL tester, framing machine, junction box equipment, cleaning equipment and IV tester.
Solar panel laminator
Solar panel laminator is a set of vacuum technology, pneumatic transmission technology, PID temperature control technology in one of the equipment, suitable for monocrystalline silicon cell module, polycrystalline silicon cell module laminating production.
The principle of solar panel laminator is to exert a certain pressure on the surface of each layer of material in the component, and press these substances tightly together under the state of heating. It is usually composed of four major systems: heating system, vacuum system, pneumatic system and control system.
The lamination process is a key step in component production. The laminating process of the components is: put the laid battery into the laminating machine, extract the air in the component through vacuuming, and then heat EVA to melt the battery, glass and backplane to bond together; Finally cool and remove the laminated components.
Bussing machine
In the manufacturing process of photovoltaic modules, it is necessary to set multiple welding strips in parallel on the surface of the cell. The ends of the welding strips are set outside the two sides of the cell. Busbars are set on the sides of the sides to weld and connect with the welding strips, and the current is collected through the welding strips.
The function of the busbar welding machine is to complete the interconnection welding process of the busbars of photovoltaic modules, including the arrangement of the busbars at the junction box end and the non-junction box end, the cutting and bending of the busbars, and the welding of the welding strips and the busbars.
The main structures of the busbar welding machine include a feeding module, a busbar cutting machine, a welding machine, a transmission welding station, a frame module, etc.
