Problems solved by technology

[0003] Slow-curing (moisture-curing polyurethane) glue has good bonding performance and excellent weather resistance, but slow-curing (moisture-curing polyurethane) glue requires a long time to hold pressure when bonding. Slow completion of curing requires a lot of space and a lot of pressure-holding tooling, which wastes a lot of manpower and material resources and wastes production and processing time

Abstract

The invention discloses a slow-curing gluing process and device for a panel and a frame. The gluing device comprises a supporting table, manipulators, glue dispensing devices, a laser marking device and pressing devices, wherein the manipulators comprise the frame feeding manipulator, the panel feeding manipulator and the discharging manipulator, the number of the glue dispensing devices is two, and the pressing devices comprise the hot pressing device and the cold pressing device. The two glue applying devices are arranged to apply glue to the frame twice, and the two pressing devices are also used after glue applying for hot pressing and cold pressing on the panel and the frame after covering separately. Slow-curing moisture polyurethane glue can be melted when heated through hot pressing, and better bonding is achieved under the action of pressure; and meanwhile, the slow-curing glue after bonding is instantly cured through the cold pressing device, and the bonding efficiency is improved while the bonding quality is improved.

Description

technical field [0001] The invention relates to a bonding device used on a panel and a frame, in particular to a slow-cure bonding process and bonding device for a panel and a frame. Background technique [0002] Common mobile phones, tablets, switches and other devices generally include a panel and a frame for installing the panel. In order to ensure the close connection between the panel and the frame, the panel and the frame are generally connected by glue. In the early days, double-sided adhesive tape or pressure-sensitive hot-melt adhesive was used as the bonding medium. Hot melt adhesives can quickly reach the strength required for bonding under heating and cooling conditions, but their weather resistance is poor. With the improvement of product quality requirements, double-sided adhesives and hot-melt adhesives can no longer meet the demand. Slow-curing (moisture-curing polyurethane) adhesives have gradually replaced double-sided adhesives and hot-melt adhesives du...
