Embodiment 1

[0023] Hereinafter, the glass material back shell and metal border structural bonding are set up in conjunction with mobile phone production.

[0024] Step 1: The coating (example is an epoxy) and is attached to the metal border over the metal border over the glue-monitoring back shell, and the edge is overlapped;

[0025] Step 2: Secure the glued back shell and the border using the fixture and apply pressure on the glue wire. The structural assembly assembly and the clamp in the holding state are placed on the conveyor belt, conveyed into the variable frequency microwave heating furnace, and the variable frequency microwave heating furnace can generate a variable frequency microwave, the present embodiment C-band microwave (eg figure 2 Indicated by it);

[0026] Step 3: For different grades of glue, select the corresponding warming program, start the microwave heating furnace, produce high-speed change electromagnetic fields, acting on the glue material coating. The process is ab...

Abstract

The invention provides application of variable-frequency microwaves in drying and curing a gluing material coating of an electronic product. The gluing material coating of the electronic product is dried and cured through variable-frequency microwaves, the curing efficiency can be effectively improved, the curing time can be greatly shortened, the original gluing curing time of dozens of minutes can be shortened to be within 1 minute, automation of the gluing link in product production can be achieved, and the original productivity bottleneck is broken through.

Description

Technical field [0001] The present invention relates to the technical field of production preparation of electronic products, in particular, to the field of drying curing techniques of glue materials in electronic products. Background technique [0002] Currently, mobile phones, tablets and more, its structural components have more and more non-metallic materials such as high molecular materials and glass materials (eg, resins, glass, ceramics), and the production assembly process is large. Appear figure 1 Indicated. The glueing link needs to be rubbed, dry solidify, and cooling. This process time is long under natural conditions, and the cured time of the glue is even for dozens of minutes. In order to shorten the glue time, the current manufacturer has adopted the completed process flow under high temperature conditions. Even though, the high temperature curing time is usually up to a few minutes. It can be seen that the overall glue time is still a major bottleneck that restri...
