Description

Repair film of no-process-side lamp panel, cutting method and positioning jig thereof Technical Field The application relates to the technical field of lamp panel processing, in particular to a repair film of a lamp panel without a process side, a cutting method and a positioning jig thereof. Background In the production and repair process of the LED lamp panel, the problems of air bubbles, edge pressing deformation and the like are easy to occur due to the lack of effective support of a film material during film pasting because of the design of a part of the lamp panels (such as P0.93 lamp panels without process edges), and meanwhile, the defects of cutting white edges, curling edges, out-of-tolerance size and the like are easy to generate due to the characteristic of a film material adhesive layer and the limitation of a positioning mode in the cutting process, so that the splicing effect and the service performance of the lamp panels are affected. In the prior art, when a common film sticking jig is adopted for film sticking, the problems of inconsistent left and right distances, edge bubbles and the like are easy to occur on process edges, the subsequent cutting risk is higher, when a non-limiting jig is adopted, the edges of a film material are unsupported, the downward pressing deformation and the indentation of a steel plate are easy to occur during film pressing, in the cutting process, a cutting knife is easy to wind residual glue, the cutting quality is reduced, the positioning mode of a four-corner bonding pad is easy to cause dimension out-of-tolerance, obvious white edges exist during splicing, and the product quality is seriously affected.
