Dispensing permeation technology and dispensing equipment

Abstract

The invention discloses a dispensing permeation technology and dispensing equipment. The dispensing permeation technology includes the steps that a front shell assembly and a touch pad of a mobile terminal are assembled, and the temperature of the front shell assembly and the temperature of the touch pad are kept at a first set temperature; the dispensing equipment is used for dispensing flowing-state PUR glue at a second set temperature onto the gap between the front shell assembly and the touch pad, and thus the glue can permeate into the gap between the front shell assembly and the touch pad after first set time; and the glue viscosity at the second set temperature is not larger than 3000CPS. By means of the dispensing permeation technology provided by the invention, the purpose of assembling the TP and the front shell assembly at first and then executing the glue spraying sticking technology is achieved in the dispensing permeation technology, and accordingly the dispensing permeation technology and dispensing equipment can be applied to producing narrow-bezel and non-bezel mobile phones. The equipment cost, consumable cost and glue scraping artificial processing cost are reduced, the production first pass yield is increased, product appearance quality is improved, and the practicability is obvious.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a glue dispensing penetration process and a glue dispensing equipment. Background technique [0002] At present, the middle and high-end mobile phones on the market generally adopt the ordinary glue dispensing assembly process, while the narrow frame and borderless mobile phones adopt the glue spraying process. These two mainstream assembly production processes have their own obvious advantages and disadvantages. The following briefly introduces the advantages and disadvantages of these two processes: [0003] The advantages of ordinary dispensing process are: mature dispensing equipment, simple process application, and low production cost. The disadvantages are: the precision of the glue line is not enough, the amount of glue is greatly affected by the deformation of the product, it cannot be applied to the production of mobile phones with too narrow borders and...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a glue dispensing and penetration process, which can reduce the cost of equipment, consumables, and manual processing of scraping glue, improve the production straight-through rate and product appearance quality, and solve the common problems. The glue process cannot be applied to the process sequence of assembling the TP and the front shell components first, and then spraying the glue, and realizing the production of mobile phones with too narrow borders and borderless
