Manufacturing method of PET bottom plate and mother plate combined film

Abstract

The invention discloses a manufacturing method of a PET bottom plate and mother plate combined film. The combined film comprises a large rubber roller assembly, a guide roller, a PET bottom plate and a mother plate, the PET bottom plate is respectively connected with the large rubber roller assembly and the guide roller, the large rubber roller assembly drives the PET bottom plate to reciprocate, the combined film further comprises a splicing fixing piece, a pre-coating roller assembly, a liquid tank assembly and an ultraviolet curing lamp, the splicing fixing piece is matched with the PET bottom plate and the mother plate, the pre-coating roller assembly is matched with the liquid tank assembly and makes contact with the PET bottom plate, and the mother plate is matched with the PET bottom plate and the ultraviolet curing lamp. According to the PET bottom plate and mother plate combined film manufactured through the method, the problem that a traditional mother plate is spliced through an adhesive tape, so that huge waste is caused in the cutting procedure is solved, a protective film does not need to be used, and the cost is low; meanwhile, the problem that the laser splicing cost is high is solved; and the PET bottom plate and mother plate combined film manufactured by the method is uniform in coating of the coating agent, so that the problems of bulges, recesses and the like cannot occur when the PET bottom plate and the mother plate are bonded, and the preparation efficiency of the combined film is improved.

Description

technical field [0001] The invention relates to the technical field of film splicing, in particular to a method for manufacturing a film combined with a PET bottom plate and a mother plate. Background technique [0002] Splicing technology is a technology used for soft films, which belongs to the technical field of optical film equipment. Plays an integral role in the pia mater. At present, there are two splicing methods. The first one is to use adhesive tape with silicone components to splice directly. The part of the splicing tape needs to be cut later, but there will be a huge amount of waste when cutting; The cutting part will crush the film, and the edge protection film has to be used in order to prevent the film from being pressed out when it is rolled up, which will lead to an increase in cost. The second is to use laser splicing technology, but laser splicing equipment is expensive, and it is necessary to purchase additional special laser tape for laser splicing eq...
