Abstract

The invention discloses a dispensing and curing process for a touch screen, and belongs to the technical field of touch screen preparation. The dispensing and curing process comprises a primary curingstage, an inspection stage and a secondary curing stage; in the primary curing stage, low-power curing is adopted, wherein the power is 80 - 90 W / cm, and the curing time is 15 - 20 s; and in the inspection stage, the humidity of glue on the touch screen is detected through multiple irradiation of an inspection table, wherein the inspection table carries out infrared ray irradiation 3 - 5 s. According to the dispensing and curing process for the touch screen, the curing process is divided into the three stages so that the time and the curing power can be strictly controlled, and the cost can be effectively controlled; the glue in the touch screen is preliminarily cured so that the glue in the touch screen can be prevented from bubbling; by adding three times of sampling in the inspection stage, the accuracy of detecting the humidity of the glue on the touch screen can be ensured; and secondary curing is adopted, and nitrogen-containing steam is introduced in the curing stage so that the interference of foreign gas in air on curing can be reduced, and cracking of the touch screen caused by too fast curing during curing can be avoided.

Description

technical field [0001] The invention relates to a curing process, in particular to a touch screen glue dispensing curing process, which belongs to the technical field of touch screen preparation. Background technique [0002] Glue dispensing and curing is an important step in the manufacturing process of mobile phone touch screens. The traditional curing process does not have a distinction between the temperature and time of the stages, resulting in a prolonged process cycle, increased costs, and is prone to cracks. Contents of the invention [0003] The main purpose of the present invention is to provide a touch screen glue dispensing and curing process in order to solve the deficiencies of the prior art. [0004] The purpose of the present invention can be achieved by adopting the following technical solutions: [0005] A touch screen glue dispensing curing process, including a preliminary curing stage, an inspection stage and a secondary curing stage; in the initial cu...
