Laminating roller mechanism

Abstract

The invention discloses a laminating roller mechanism. The laminating roller mechanism comprises a mounting base; a roller assembly which comprises an attaching roller and a supporting roller, whereinthe attaching roller is installed on the mounting base through a first bearing and the supporting roller is mounted on the mounting base through a second bearing, is positioned right below the attaching roller and can be tangent to the attaching roller; a jacking air cylinder which is installed on the mounting base and connected with the roller assembly, wherein the jacking air cylinder can drivethe roller assembly to ascend and descend. According to the invention, the supporting roller is arranged below the attaching roller. When OCA is attached to a cover plate, support can be provided forthe attaching roller, the situation that the attaching effect is affected due to the fact that the middle position of the attaching roller is irreversibly deformed under the action of attaching pressure is prevented, the service life of the attaching roller is prolonged, and the situation that the product production efficiency is reduced due to frequent replacement of the attaching roller is avoided; and the supporting roller tangent to the attaching roller can enable the attaching roller to roll more smoothly, so that the attaching effect of a product is further improved.

Description

technical field [0001] The invention relates to the technical field of optical glue bonding, in particular to a bonding roller mechanism. Background technique [0002] During the LCD panel assembly process, one of the processes is to bond the OCA (Optically Clear Adhesive) and the cover plate softly to hard. The prior art discloses a roller laminating device, which includes a roller, bearings located at both ends of the roller and a cylinder below the roller. The laminating platform is laminated along the vertical direction of the rollers. [0003] The above-mentioned roller bonding device has the following defects in the actual application process: [0004] (1) In the bonding process, in order to ensure that no air bubbles are generated, it is necessary to reduce the contact area between the roller and the OCA as much as possible, so the diameter of the roller needs to be made very small, which leads to the roller with a smaller diameter Plastic deformation is prone to o...

Problems solved by technology

[0004] (1) In the bonding process, in order to ensure that no air bubbles are generated, it is necessary to reduce the contact area between the roller and the OCA as much as possible, so the diameter of the roller needs to be made very small, which leads to the roller with a smaller diameter Plastic deformation is prone to occur under the action of bonding pressure, especially the middle position of the roller is prone to sag, so that the OCA cannot be closely attached to the middle position of the roller, that is, the OCA corresponding to the middle position of the roller bears less pressure from the roller, resulting in Poor fit, even air bubbles;

[0005] (2) After the irreversible deformation occurs in the middle position of the roller, it needs to be replaced and maintained regularly, which will affect the production efficiency of the machine and increase the production cost of the product
