Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module production equipment, and particularly relates to a novel photovoltaic module adhesive film flattening device. Background Art

[0002] Photovoltaic adhesive film is an important encapsulation material for photovoltaic modules, used in the production of photovoltaic modules to protect the batteries inside the modules. According to different product structures, it is divided into EVA film (ordinary transparent EVA film, white EVA film), POE film, etc. The technical route of the adhesive film is relatively stable, and there are basically no substitutes. During the production process of photovoltaic modules, the laying of the adhesive film is directly related to the yield of the modules, because the unevenly laid adhesive film is prone to generate bubbles during the lamination process, causing the solder ribbon to shift, and even leading to hidden cracks in the battery, resulting in losses.

[0003] After the photovoltaic module adhesive film is laid, due to the shrinkage of the adhesive film itself, during the process of the production line, the adhesive film is prone to shrink and bulge. At this time, when the module passes through the typesetting machine and the string welding machine to suck the strings, it is extremely easy to cause hidden cracks and broken pieces of the battery cells at the bulging part of the adhesive film, resulting in an increase in the fragmentation rate and the rework rate; with the increase in the production capacity of the production line, limited by the use design of the production line space, the repair workbench is limited, which is extremely easy to cause congestion in the production line.

[0004] Currently, the existing adhesive film flattening device uses an integrated pressure roller. The installation location and position are limited by the adhesive film cutting and laying machine. Its flattening effect only acts on the arching phenomenon of the adhesive film caused by the laying machine, and it cannot solve the arching phenomenon caused by the shrinkage of the adhesive film during the process of the production line.
