Abstract

The invention discloses a pressure holding fixture. The pressure holding fixture comprises a plurality of fixture units. The middle portion of the first surface of each fixture unit is provided with a groove used for containing a pressed object. The first surface of each fixture unit serves as a lower fixture surface. The second surface of each fixture unit serves as an upper fixture surface. The upper fixture surface of one fixture unit can be matched with the lower fixture surface of the other fixture unit to complete the pressure holding action. The periphery of each groove is provided with a plurality of first magnetic mechanisms. The second surface of each fixture unit is provided with a plurality of second magnetic mechanisms with the magnetism opposite to the first magnetic mechanisms; or, the second surface of each fixture unit is provided with a plurality of metal absorption mechanisms capable of being attracted by the first magnetic mechanisms. The second magnetic mechanisms are absorbed by the corresponding g first magnetic mechanisms in a matched mode. According to the pressure holding fixture provided by the invention, the obverse sides serve as lower fixture bodies, and the reverse sides serve as upper fixture bodies. The fixture structure is simplified. The mold and fixture cost is saved (originally two fixtures are needed, and now only one fixture is needed.).

Description

technical field

[0001] The invention belongs to the technical field of pressure maintaining equipment, and relates to a pressure maintaining fixture, in particular to a pressure maintaining fixture for a mobile phone. Background technique

[0002] When the narrow frame of the mobile phone TP or the back glue cannot meet the die-cutting and bonding strength, it will be applied to the structural hot-melt adhesive dispensing process. The hot melt glue dispensing process is as follows: heat the glue to about 120 degrees, extrude it onto the casing through a glue dispenser, bond and solidify with TP, and fix it with a pressure holding fixture. The curing time is about 4 hours.

[0003] The principle of the pressure-holding fixture: the pre-pressed front shell assembly is placed between the upper and lower clamping fixtures of the existing pressure-holding fixture. Press to cure the structural adhesive between the shell and TP to achieve optimal adhesion and consistent height dim...
