Stacked type pressure maintaining box group

Abstract

The invention provides a stacked type pressure maintaining box group, which comprises at least two box cover bodies of the same structure, and the two box cover bodies of the same structure are arranged to be buckled in a relative movement mode in the same direction or disassembled in a back-to-back mode. By adopting the box cover bodies with the structure, two box cover bodies can be used for maintaining the pressure of one mobile phone, three box cover bodies can be used for maintaining the pressure of two mobile phones, four box cover bodies can be used for maintaining the pressure of three mobile phones, and the like, so that the stacked type pressure maintaining box group provided by the invention has the advantages that the thought is ingenious, and the use number of the box cover bodies is reduced when the pressure of the same number of mobile phones are maintained; a working table top can be kept clean and tidy through a stacking mode, and the occupied area of the working table is reduced; and if the mobile phone to be subjected to pressure maintaining needs to apply pressure to pressure maintaining boxes through special equipment, pressure can be applied to the multiple pressure maintaining boxes at the same time, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mobile phone processing devices, and in particular relates to a stacked pressure holding box group. Background technique [0002] Smartphones have many parts and complex processes. The process stages that a mobile phone goes through from parts assembly to finished products are: dispensing and pressure-holding, assembly, testing, and packaging. From parts to finished products, the number of transfers for a product is as high as 500. more than times. Among them, glue dispensing and pressure holding are a process of installing the mobile phone screen on the middle frame of the mobile phone, that is, applying glue on the middle frame of the mobile phone, and then bonding the screen and the middle frame, in order to prevent the screen and the middle frame from being glued during the glue solidification process. If there is a deviation in the bonding position, the middle frame and the screen need to be fixed, ...

Among them, glue dispensing and pressure holding are a process of installing the mobile phone screen on the middle frame of the mobile phone, that is, applying glue on the middle frame of the mobile phone, and then bonding the screen and the middle frame, in order to prevent the screen and the middle frame from being glued during the glue solidification process. If there is a deviation in the bonding position, the middle frame and the screen need to be fixed, and can only be taken out after the glue solidifies; at present, most of the industry adopts the previously eliminated dovetail clips and magnet adsorption pressure-holding box pressure-holding processes. With the changes in smart phones, Especially the narrow frame, this method has a certain risk to the pressure holding effect
