Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production and processing of OCA optical adhesive, and specifically relates to an OCA optical adhesive degassing device. Background Art
[0002] OCA optical adhesive degassing equipment, also known as degassing machine, is a device specially used to deal with the bubble problem in OCA optical adhesive. During the coating and curing process of optical adhesive, the presence of bubbles will seriously affect the optical performance and appearance quality of the product.
[0003] 0CA optical adhesive is relatively transparent, and the bubbles generated inside it can be easily found. Therefore, it is generally used to achieve adhesion effects on various films. When the 0CA optical adhesive is bonded to the film for use, the bubbles in the 0CA optical adhesive need to be removed. Usually, roller-type squeezing is used to remove the bubbles on the 0CA optical adhesive.
[0004] However, in actual use, during the extrusion process, some of the colloid between the two films will be squeezed out, and the extruded colloid will stick to the roller. For this reason, the existing 9CA optical adhesive degassing equipment will remove the adhered colloid through a scraper. However, due to the excessive viscosity of the 0CA optical adhesive, the situation is more complicated, resulting in poor scraping effect. For this reason, we propose an OCA optical adhesive degassing equipment. Utility Model Content
