Description

Method for structure and water pressure defoaming method of water material debonding device for optical material bonding glue layer

The invention relates to a structure of a water-pressure defoaming device for an optical material bonding adhesive layer and a method for hydraulic defoaming, which is applied to a defoaming body of a colloidal colloid of each optical material of a liquid crystal panel, a touch panel and the like.

The touch panel includes a plurality of optical materials such as an upper glass, a sensing layer, and a liquid crystal display layer. The optical materials are difficult to avoid when the optical materials are attached to each other. Therefore, it is necessary to take off In the process of foaming, the touch panel semi-finished products which are made up of the respective optical materials are overlapped with each other in the oven, and the weight of the touch panel is placed on the top of the overlapping touch panels, and the oven is applied with a temperature of 80 ° C. The viscosity coefficient of the colloid of each optical material is decreased, so that the colloid is subjected to pressure to discharge the air bubbles, and then cooled and cooled to remove the defoaming.

However, the semi-finished products of the touch panel overlap each other, and the weight of the touch panel is pressed at the top, which causes the weight and pressure of the semi-finished products of the touch panel to be different, and the temperature of the oven is not evenly affected by the 80 ° C temperature applied thereto. Temperature, the main reason is that the touch panel semi-finished products overlap each other, it is difficult to directly receive the temperature, so that the viscosity coefficient of the colloids of the optical materials is not evenly reduced, so that the probability of incomplete bubbles is increased, and when cooling The speed of each touch panel is not equal, and the temperature of the oven is not lowered with the temperature of the oven space.
