Embodiment Construction
[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only Some, but not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] The embodiment of the present invention solves the problem that the upper die assembly and the lower die assembly have separate punching devices, and the position of the upper die assembly relative to the lower die assembly tends to shift, resulting in tool wear and punching deviation. problem, a punching device is proposed. The specific technical scheme is as ...

The invention discloses a punching device which comprises an upper cutting die assembly, a lower cutting die assembly, a connecting assembly and a driving device, wherein the upper cutting die assembly comprises an upper cutting die frame and a punching cutter installed on the upper cutting die frame; the lower cutting die assembly is located below the upper cutting die assembly and comprises a lower cutting die frame and a cutter hole which is formed in the lower cutting die frame and matched with the punching cutter; the connecting assembly comprises a polished shaft and a bearing, the polished shaft is installed on the lower cutting die frame and upwards penetrates through the upper cutting die frame, and the bearing and the polished shaft are installed in a sleeved mode and fixed to the upper cutting die frame; and the driving device is connected with the upper cutting die frame and used for driving the upper cutting die assembly to slide along the connecting assembly. According tothe punching device, the polished shaft serves as a connecting piece of the upper cutting die assembly and the lower cutting die assembly and a guide rail for lifting the upper cutting die assembly,the upper cutting die assembly is guided to ascend and descend along the polished shaft through the bearing, and compared with a split type punching device, the structural integrity of the device is higher; and it is avoided that after long-time use, the upper cutting die assembly moves transversely relative to the lower cutting die assembly, and the punching effect and the punching function are affected.
Description
technical field [0001] The invention relates to the technical field of photovoltaic module manufacturing, in particular to a punching device. Background technique [0002] In the production process of photovoltaic modules, in order to lead the electrode lead wires out of the back plate, it is necessary to punch holes in the EVA glue and the back plate. Most of the existing punching devices have a split structure, that is, the upper die assembly and the lower die assembly are arranged correspondingly but are not connected, and the upper die is driven by the driving device connected with the upper die assembly The assembly is lifted so that the cutter in the upper die assembly passes through the knife hole in the lower die assembly, thereby achieving the effect of punching. [0003] During the long-term operation of the above-mentioned split punching device, the position of the upper die assembly is prone to shift, resulting in friction between the cutter and the cutter hole ...
