Description

Backboard EVA punching knife

Technical Field

The utility model relates to a punching cutter, concretely relates to backplate EVA punching cutter suitable for solar photovoltaic trade photovoltaic module frock field.

Background

At present, half-cell plates become the main trend of assembly production, and the lamination link has high requirements on the quality of the assembly in the assembly production process. In current subassembly production, the easy gassing of subassembly lead-out wire hole position, the leading cause is that the cutter shape that cuts of lead-out wire hole position is oval shape, cuts the in-process, can wash away the EVA glued membrane of whole hole position for the volume of gluing of this position lacks, leads to the subassembly to produce the bubble. In order to solve the problem of air bubbles generated by the assembly, the glue amount is supplemented by manually adding small glue film blocks at the position, but the method can increase the glue amount cost and needs special small block cutting personnel to increase the personnel cost. The same oval through hole is generated when the back plate is cut, so that molten adhesive film can flow out from the hole during the lamination of the assembly, and the main method for solving the problem at present is to prevent the molten adhesive film from flowing out and influencing the lamination effect of the assembly by adding a small piece of high-temperature cloth at the position, but the method needs to manually cut a lamination small piece with proper size before lamination, place the lamination small piece and remove the lamination small piece after lamination, thereby causing great material cost and labor cost. Meanwhile, due to the fact that the position of the back plate is lost, junction box glue is lost in the junction box installation process, and before the junction box is installed, junction box bonding glue needs to be manually supplemented in the position before the junction box is installed manually, so that manpower and material waste is caused.
