Description

A method and device for dispensing glue on a touch screen

technical field

The invention relates to the field of glue dispensing, in particular to a method and device for dispensing glue on a touch screen.

Background technique

At present, the display screen of a smart phone generally uses a touch screen to operate the user. Using a touch screen to operate a smart phone is much more convenient than using buttons to operate a mobile phone, and it also makes the display area of the entire mobile phone larger and more beautiful. In the prior art, the lamination of the touch screen and the upper cover of the mobile phone is basically realized by a dispensing process, and the narrower the frame of the mobile phone is, the higher the requirement for the dispensing process is. In the prior art, before dispensing glue on the touch screen through the glue dispensing process, it is necessary to go through a step of checking the glue path, that is, first dispensing glue on a white sheet (a transparent body with the same size and shape as the touch screen), and dispensing refers to the standard The glue road is the glue road road map drawn on paper by the engineer in advance according to the requirements. When the glue is dispensed, the glue dispensing path of the glue dispensing equipment is saved. There are many problems in this glue dispensing method in the prior art. For example, the glue path drawn by the engineer himself based on experience will inevitably have deviations, which makes the glue path easy to deviate, and eventually leads to weak and reliable bonding between the touch screen and the top cover of the mobile phone. Sex test failed and other issues. Even if the engineer draws the dispensing route of the touch screen of a mobile phone model correctly, it is still easy to deviate from the route of the dispensing route of the touch screen of the new mobile phone model, especially if a different engineer is changed. In other words, because each engineer draws the glue road based on their own experience, it is difficult to draw the glue road exactly for different mobile phone models. The glue paths drawn by such people in the prior art are generally not foolproof, and the painted glue paths are easily lost later.
