Technical Field

[0001] This utility model relates to the field of solar panel processing technology, specifically to a composite film lamination device for solar panels. Background Technology

[0002] In the photovoltaic industry, the packaging quality of solar panels directly determines their power generation efficiency and service life. Composite film lamination is the core step in the packaging process. By pressing and bonding the multi-layer structure from glass to composite film to cell to composite film to backsheet under specific temperature, pressure and vacuum conditions, the sealing protection and mechanical support of the cells are achieved.

[0003] The prior art discloses a PVC composite film lamination processing device with announcement number CN215755477U, including a device body; a receiving roller is provided inside the device body; a disassembly mechanism is provided inside the device body, and the disassembly mechanism includes a fixed seat. The fixed seat is movably connected to the inner wall of the device body through a bearing, and a first sliding groove is opened inside the fixed seat. A first slider is slidably connected inside the first sliding groove, and the left side of the first slider is fixedly connected to the outer wall of the receiving roller. An insert is inserted through the fixed seat, and the bottom end of the insert is inserted into the first slider. By pulling the handle, the receiving roller can be easily removed, which reduces the difficulty of the work for the staff compared with the past and realizes the function of quick disassembly of the receiving roller.

[0004] The aforementioned composite film lamination device for solar panels solves the problem of inconvenience for workers in removing the PVC composite film from the outer wall of the receiving roller, thus improving their work efficiency. However, while the device facilitates the removal of the composite film through easy disassembly, it cannot utilize bimetallic sealing strips for assisted demolding, nor can it achieve phase change based on temperature for convenient sealing and demolding. Disassembling the device still requires a significant amount of time, resulting in poor performance during use. Improvements are needed in these areas. Utility Model Content
