Description

Technical Field

[0001] The utility model relates to the technical field of automation, and particularly relates to an EVA strip laying machine. Background Technique

[0002] EVA refers to ethylene-vinyl acetate copolymer. When the content of vinyl acetate in EVA is less than 20%, it can be used as a plastic. EVA has good low-temperature resistance, and its thermal decomposition temperature is relatively low, about 230°C. As the molecular weight increases, the softening point of EVA rises, the processability and the surface gloss of plastic parts decrease, but the strength increases, and the impact toughness and environmental stress cracking resistance improve. In terms of chemical resistance and oil resistance, EVA is slightly worse than PE and PVC, and the change is more obvious with the increase of vinyl acetate content. EVA films are often laid on the surfaces of various materials, which requires an EVA strip laying machine. In the existing production line, the EVA at the head and tail overflows with glue unevenly after lamination, and there is a quality risk of air bubbles at the busbars at the head and tail of the laminated module. Placing EVA strips at the busbars at the head and tail of the module can ensure that the EVA overflows with glue evenly after lamination and avoid quality risks.

[0003] The current EVA strip laying machines can basically meet people's usage requirements, but there are still some problems, which are described as follows:

[0004] 1. The problem that the EVA strip laying machine is difficult to produce automatically. In the existing production line, the EVA at the head and tail overflows with glue unevenly after lamination, and there is a quality risk of air bubbles at the busbars at the head and tail of the laminated module. The placement of the EVA small long strips at the head and tail of the pre-laminated module is all manually operated, wasting manpower.

[0005] 2. The problem that the EVA strip laying machine is difficult to cut EVA. When processing EVA, it is difficult to automatically align and cut, and manual cutting wastes manpower, and the device is not convenient to work. Content of the Utility Model
