Description

Technical Field

[0001] The present invention relates to the technical field of optical adhesive bonding, and in particular to a bonding roller mechanism. Background Art

[0002] During the assembly of liquid crystal panels, one of the processes is to perform soft-to-hard bonding of OCA (Optically Clear Adhesive) and the cover plate. The prior art discloses a roller bonding device, which includes a roller, bearings at both ends of the roller, and a cylinder below the roller. The bonding platform is located above the roller, the cylinder lifts up the roller, and then the servo motor drives the bonding platform to bond along the vertical direction of the roller.

[0003] The above roller laminating device has the following defects in practical application:

[0004] (i) During the lamination process, in order to ensure that no bubbles are generated, the contact area between the roller and the OCA needs to be reduced as much as possible. Therefore, the diameter of the roller needs to be very small. This causes the roller with a smaller diameter to be easily plastically deformed under the lamination pressure, especially the middle part of the roller is prone to depression, making it impossible for the OCA to be closely attached to the middle part of the roller. That is, the OCA corresponding to the middle part of the roller is subjected to a smaller roller pressure, resulting in poor lamination and even bubbles.

[0005] (ii) After the middle position of the roller undergoes irreversible deformation, it needs to be replaced and maintained regularly, which affects the production efficiency of the machine and increases the production cost of the product. Summary of the invention

[0006] The object of the present invention is to provide a laminating roller mechanism, which can prevent the laminating roller from being deformed while ensuring the laminating effect between the OCA and the cover plate.
