Bonding device used for bonding metal shell body with plastic shell body

Abstract

The invention discloses a bonding device used for bonding a metal shell body with a plastic shell body. The bonding device comprises a bearing table, a press sheet and a location element arranged on the bearing table, wherein the bearing table is used for bearing the plastic shell body; the location element is used for being inserted into a location hole of the deformed plastic shell body and keeping the deformation of the plastic shell body; the press sheet is used for applying a force onto the metal shell body and transmitting the metal shell body towards the plastic shell body; and when themetal shell body is transmitted to a predetermined position, the plastic shell body and the metal shell body are arranged at an interval, so that bonding between the plastic shell body and the metalshell body is realized through an adhesive when the plastic shell body recovers the deformation. On this basis, according to the bonding device, the adhesive on the outer side surface of the plastic shell body can be prevented from being scraped in the bonding process for the metal shell body and the plastic shell body, so that improvement for the bonding effect of the metal shell body and the plastic shell body, and lowering for the assembly yield of products are benefited.

Description

Technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a bonding device for bonding a metal shell and a plastic shell. Background technique [0002] Current electronic terminals are increasingly moving towards the trend of metal elements. For example, metal battery covers have become the general trend of the smart electronic equipment industry. In this type of structural design, in order not to affect the communication commands of the antenna, the electronic terminal needs to be compatible with plastic shells. The body, that is, the metal shell must be bonded and matched with the plastic shell through glue. See figure 1 with figure 2 As shown, the side of the metal shell 11 is provided with an inwardly extending barb 111. During the pressing down of the metal shell 11 and bonding with the plastic shell 12, the barb 111 will interact with the plastic shell 12. The outer surface of the plastic shell 12 touches and scratches, ...

Problems solved by technology

see figure 1 and figure 2 As shown, the side of the metal shell 11 is provided with a barb 111 extending inward. During the process of pressing down the metal shell 11 and bonding with the plastic shell 12, the barb 111 will contact with the plastic shell 12. The outer surface of the metal shell 11 contacts and scratches, thereby scraping off the glue coated on the outer surface of the plastic shell 12, affecting the bonding effect between the metal shell 11 and the plastic shell 12, and reducing the assembly yield of the product
