Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic component manufacturing, in particular to a photovoltaic component EVA pad strip cutting and fixing device. Background Art
[0002] In the production process of photovoltaic modules, EVA film is needed for battery packaging, which mainly plays the role of protecting the battery and fitting the battery cell tightly to the cover glass. Specifically, when laying EVA, a busbar hole is first opened at the center hole of the EVA, the machine gripper grabs the EVA and lays it, and then a cutter is used to cut it. Due to the existence of spot heat, the front film is not easy to offset when running on the assembly line, while the rear film is prone to EVA offset, resulting in poor edge glue overflow and bubble groups after lamination of the photovoltaic modules. For this reason, EVA pads need to be laid to avoid the above situation. EVA pads are generally cut manually. Since EVA itself has good elasticity and sliding properties, workers manually press the stacked EVA for cutting as a whole, which is prone to offset, resulting in deviation of the cut EVA pads, affecting subsequent use. In addition, the workload and fatigue of workers who manually press are large, and the overall cutting efficiency is low. Utility Model Content
[0003] In view of the above, the utility model provides a photovoltaic module EVA pad cutting and fixing device, which is used to press and fix the stacked materials when cutting the EVA pad.

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0016] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "setting", "connection", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0017] Reference Figure 1 The photovoltaic module EVA pad strip cutting and fixing device of this embodiment includes a base 1, a tension spring 2 and a pressure plate 3. A slide bar 11 is fixed on the base 1. The pressure plate 3 is a rectangular long strip with a concave structure. The pressure plate 3 is movably arranged on the slide bar 11 of the base 1. The two ends of the tension spring 2 connect the base 1 and the pressure plate 3.
[0018] Specifically, if Figure 2-Figure 3 The pressing plate 3 includes a fixing portion 31 at both ends and a pressing portion 32 in the middle. The pressing portion 32 of the pressing plate 3 has a pressing groove 34 on its bottom surface for placing the stacked EVA layers. A sliding channel 33 is provided inside the fixing portion 31. The pressing plate 3 is slidably connected with the slide bar 11 through the sliding channel 33. The pressing plate 3 is movably arranged above the base 1 to adapt to EVA cutting work of various thicknesses. There are two slide bars 11, corresponding to the two sliding channels 33 on the pressing plate 3, so that the pressing plate 3 is more stable when it is lifted and slid on the base 1 and is not easy to deflect.
[0019] In addition, a mounting ring 12 is fixed on the base 1 , and a mounting ring 12 is also provided on the side of the fixing portion 31 of the pressure plate 3 . Both ends of the tension spring 2 are hung on the two mounting rings 12 .
[0020] Furthermore, the photovoltaic module EVA pad strip cutting and fixing device also includes a mounting clamp 4 and a workbench 5, wherein the mounting clamp 4 is used to clamp the base 1 on the workbench 5. The mounting clamp 4 is a detachable G-shaped clamp, which is convenient for workers to install and disassemble, and effectively reduces the workload of workers.
[0021] Before cutting the EVA strips, use a G-shaped clamp to fix the base 1 to the edge of the workbench 5 and clamp it, manually lift the pressing plate 3, and neatly push the multi-layer EVA stack into the pressing groove 34 below the pressing plate 3. After releasing the pressing plate 3, since there are two tension springs 2 between the pressing plate 3 and the base 1, the pressing plate 3 can clamp the EVA stack to prevent EVA from sliding and solve the deviation problem when cutting the EVA strips. If you need to cut EVA strips of different widths, you only need to remove the tension springs 2 on both sides, take off the pressing plate 3, and replace the pressing plates of different widths. The operation is convenient.
