Problems solved by technology

The infrared heating furnace can only achieve the leveling effect of the glue, but cannot effectively eliminate the problem of air bubbles
Therefore, in the water-glue process, the performance requirements for the dispensing equipment, the quality requirements for the glue, and the technical capabilities of the team are relatively strict, which virtually increases the production cost.

Abstract

The invention discloses a rapid defoaming and leveling process for glue processing. The rapid defoaming and leveling process comprises the following steps: A, choosing glue with corresponding viscosity according to the size of a capacitive screen and using a glue machine to dispense glue; B, putting a product with the glue dispensed into a defoaming machine for defoaming and leveling through pressurizing and warming; C, pre-curing the product which is leveled, and cleaning the overflown glue around the cured product; and D, fully curing the pre-cured product by using an ultraviolet light curing oven. According to the rapid defoaming and leveling process for the glue processing, defoaming and leveling are achieved through the pressurizing and warming modes, the yield of the glue processing process is increased, the performance requirements of the glue process on staffs, equipment and the glue are reduced, so that the production cost is lowered, and the rapid development of the glue laminating process is promoted.

Description

technical field [0001] The invention relates to the technical field of water gel manufacturing process, in particular to a rapid defoaming and leveling process of water gel manufacturing process. Background technique [0002] In the touch screen industry, G+G (glass cover plate + glass functional sheet) capacitive screen product bonding process basically adopts two methods: solid optical adhesive (OCA) and liquid optical adhesive (LOCA). With the advantages of low product cost control and high yield rate, LOCA is becoming more and more popular in touch screen products. In order to improve efficiency in the water glue manufacturing process, the assembly line layout is generally adopted. The assembly line is basically composed of a dispensing machine, an infrared heating furnace (IR furnace), an ultraviolet curing furnace (UV curing furnace) and an assembly line frame. Taking the G+G capacitive screen as an example, in the water-glue bonding process, the generally used proce...
