Vacuum laminating machine for producing photovoltaic cell module

Abstract

The invention relates to the technical field of photovoltaic production equipment, and also provides a vacuum laminating machine for producing a photovoltaic cell module. The vacuum laminating machinecomprises a machine body, a lower vacuum chamber is fixedly mounted at the top of the machine body, a lifting air cylinder is fixedly mounted in the machine body, a lifting hinge frame is movably connected to an output shaft of the lifting air cylinder, and an upper vacuum chamber is fixedly mounted at the bottom of the top end of the lifting hinge frame. According to the vacuum laminating machine for the producing the photovoltaic cell module, in the descending process, a heating plate is in contact with transmission strips and the top of a spring-shaped limiting column, the tops of the transmission strips are pressed down to enable the other end to drive a control poking piece to ascend; when the control poking piece ascends, resistance in a magnetic variable resistance controller is gradually weakened, magnetism of a first magnetic block is gradually enhanced, mutual exclusion force between a second magnetic block and the first magnetic block is gradually enhanced, the second magnetic block ascends gradually to be prevented from making contact with the heated heating plate, and bubbles generated by uneven heating due to the fact that the bottom makes contact with the heating plate and melts rapidly are avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic production equipment, in particular to a vacuum laminator for production of photovoltaic cell components. Background technique [0002] The manufacturing process of photovoltaic cell modules mainly includes the following steps: laser scribing-light welding-manual welding-stacking-middle test-lamination-curing-packaging-final test, in which, after the cells are welded as required, they are laminated First, use a multimeter to check whether the welded photovoltaic cells have a short circuit through the voltage of the side battery, then clean the glass, tailor EVA and TPT according to the size slightly larger than the glass area, and after the materials are laminated, put them into the laminate machine for lamination.

Problems solved by technology

[0003] Elimination of air bubbles in EVA during lamination is the key to the success of encapsulation. Oxygen generated by the cross-linking reaction of air entering into EVA during lamination is the main reason for the formation of air bubbles. The current solution to this problem is to reset the working temperature and pump air , lamination time, but this solution is limited by temperature and time, and it cannot effectively solve the problem of bubble formation in the actual production process; Orientation, the battery sheet is prone to cracks at 45 degrees, and due to uneven lamination pressure, it is also prone to debris problems
