Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solar component manufacturing, in particular to a device capable of cutting EVA strips in batches. Background Art
[0002] In the lamination process of producing double-glass solar panels, a long EVA strip needs to be placed on the short sides of the glass near the busbars. Some of the EVA strips are cut manually on an off-line workbench.
[0003] The staff usually stacks 20-30 1m*1m EVA films high and evenly, presses a ruler on the EVA film, presses the ruler with the left hand, and starts to cut 1m*2cm EVA strips along the ruler with a utility knife in the right hand. Repeat this process. After 49 times, all 1m*1m EVA films are cut into 1m*2cm EVA strips. This operation method is a common method of manually cutting EVA strips.
[0004] However, during the above operation, the staff needs to press the ruler with his left hand to make the multi-layer EVA film fit tightly, and then use a utility knife to cut the EVA film along the edge of the ruler, so as to ensure neat incisions and smooth cutting. According to this operation method, continuous cutting for multiple times will cause obvious hand soreness, and long-term operation has high labor intensity. At the same time, the blade of the utility knife is thin, and it is not easy to cut the multi-layer EVA film, and it is easy to break. Utility Model Content

[0009] Preferably, the fixing mechanism comprises a press buckle and a cross bar, the press buckle is fixedly connected to one end of the press, the cross bar is fixedly connected to the upper surface of the cutting platform, and the press buckle matches the cross bar.
[0010] Preferably, one end of the cutter is fixedly connected to a handle.
[0011] Preferably, the pressing tool is in the shape of a flat strip.
[0012] Preferably, a scale is provided inside the guide rail.
[0013] Preferably, the press buckle is hook-shaped.
[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0015] 1. The utility model uses a cutter to cut EVA strips. The cutter can move left and right in a guide rail and can cut continuously, thereby realizing batch and efficient cutting of EVA strips and reducing manual fatigue.
[0016] 2. The utility model can monitor the distance moved by the slider each time in real time through the scale, so that the distance moved by the slider each time is the same, thereby making the width of the cut EVA strips the same. BRIEF DESCRIPTION OF THE DRAWINGS
