Description

Technical Field

[0002] The traditional module side panel adhesive coating, pressure holding, and heating process includes two stages: pressure holding after adhesive coating and adhesive curing. The pressure holding stage involves manually installing pressure holding fixtures, but these fixtures need to be manually removed when the module comes off the production line. After prolonged use, the clamping force of these fixtures decreases, resulting in poor assembly consistency and requiring manual verification. This process is cumbersome, affects production cycle, wastes manpower, reduces the adhesive coating area of ​​the side panels, and affects the dimensional accuracy of the modules. The adhesive curing stage involves natural resting or heating in an oven to cure the adhesive. This heating method takes a long time, has poor heating effect, requires a large area of ​​the oven, and has low heating efficiency. Utility Model Content
