Description

Technical Field

[0001] This utility model relates to the technical field of tempered glass film processing equipment, specifically a primer spraying device for bonding tempered glass film base plates. Background Technology

[0002] Tempered glass screen protectors, as accessories for electronic products, are typically used for screen protection to prevent scratches and damage, and also improve the screen's drop and impact resistance. Tempered glass screen protectors usually consist of a multi-layered structure, including a surface strengthening layer, an intermediate adhesive layer, and a base layer. The base layer is a plastic substrate used to support and protect the tempered glass during the tempered glass production process, reducing damage during processing or transportation and improving the screen protector's performance. When bonding the base layer to the surface strengthening layer, a primer needs to be sprayed onto the base layer. This primer serves as the intermediate adhesive layer of the tempered glass. However, during primer spraying, excess primer is often sprayed onto the conveyor mechanism, affecting its operation. Furthermore, primer sprayed along the edges of the base layer can also affect subsequent tempered glass processing, resulting in insufficient primer application. Utility Model Content
