[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In order to solve the problem, the current solar cell back film fixing device mainly consists of a fixed workbench, a hydraulic rod installed on the workbench, and a pressure plate installed on the telescopic part of the hydraulic rod. Although the solar cell back film fixing device of this structure can directly place the back film on the solar cell when in use, and then use the hydraulic rod to press the pressure plate directly on the solar cell, thereby achieving the back film being pressed and fixed on the solar cell. However, on the one hand, since the solar cell back film fixing device of the above structure does not pre-position the back film placed on the solar cell when in use, the back film is prone to sliding and misalignment when being pressed and fixed on the solar cell, thereby making the fixing quality of the back film on the solar cell poor. On the other hand, since the solar cell back film fixing device of the above structure mainly realizes the replacement of solar cells by taking and placing them one by one when in use, , which causes the device to take a long time to replace and remove solar cells during use, thereby causing a long downtime of the device, and cannot meet the processing requirements of the device for efficiently fixing the back films of large quantities of solar cells. On the one hand, the utility model can fix the back film on the solar cell by combining pre-compression and secondary compression under the action of the pressure plate, boss, pressure frame, sliding column, spring and storage cavity. Under such a fixing structure, the sliding dislocation of the back film during fixation can be effectively avoided, so that the fixing quality of the back film on the solar cell is improved. On the other hand, the intermittent transportation of the solar cell can be realized by cooperating with the motor, support roller and conveyor belt, and the back film of the new solar cell can be fixed at the same time during the process of removing the processed solar cell, which effectively reduces the downtime of the device and meets the processing requirements of the device for efficiently fixing the back film of large quantities of solar cells.
