Aluminum frame pneumatic engaging device for solar module

Abstract

The invention provides an aluminum frame pneumatic engaging device for a solar module. The device comprises a base plate, a lever, a stamping head, a loaded column and a pressurizing cylinder, wherein the stamping head is hinged with the left end of the lever; the lever is hinged with the upper end of the loaded column; a piston rod of the pressurizing cylinder is hinged with the right end of the lever; the body of the pressurizing cylinder is fixed on the base plate; the pressurizing cylinder is controlled by the pneumatic control device to act; and a convex body structure is arranged on the lower end surface of the stamping head. After the solar cell module is encapsulated with adhesive, the long aluminum frame is subjected to tightening and engaging treatment by the module, so that the long aluminum frame and the short aluminum frame are both firmly engaged with zigzag angles to form a whole, which can greatly reduce the phenomenon that cracks are generated among aluminum frames after the solar cell module is used outdoor for long time, and improve the sealing performance and connecting firmness of the solar cell module.

Description

technical field [0001] The invention relates to a packaging tool for a solar battery module, in particular to a packaging and engaging device for an aluminum frame of a solar battery module. Background technique [0002] The solar panel is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Its function is to convert solar energy into electrical energy. The battery laminate must be packaged and protected with a frame during outdoor applications. If the battery laminate is not well sealed, encountering rain or working in a high-humidity environment for a long time, it will accelerate the damage of the battery laminate and cause solar energy The battery board cannot work properly, and the basic requirement of the package is to be sealed. [0003] The solar cell module is glued and packaged with an aluminum frame. The long aluminum frame and the short aluminum frame are connected by corners with jagged...

AI Technical Summary

Problems solved by technology

In the existing packaging process, if the size of the corner code does not meet the predetermined requirements, it will easily loosen between the corner code and the long and short frames, resulting in cracks at the connection between the short aluminum frame and the long aluminum frame, especially for solar cell modules After long-term exposure under natural conditions, the adhesive force of the sealant will decrease, which will lead to a decrease in the bonding force between the frame and the battery laminate, and cracks are more likely to occur at the joint between the short aluminum frame and the long aluminum frame

After careful observation and analysis by the applicant, the main reason for the above-mentioned defects is that the connection between the corner bracket and the long aluminum frame is unreliable. The existing technology can only punch out tightening dimples on the inner surface of the short aluminum frame, but the long aluminum frame and the serrated pins of the corner codes cannot punch the tightening dimples. Therefore, the four connecting corners of the solar cell module are the The connection point is also a place where cracks are prone to occur, and the connection between the long aluminum frame and the corner bracket is the main cause of cracks
