A curing device for producing OCA optical adhesive

Abstract

The utility model discloses a curing device for producing OCA optical glue, which comprises a bottom box and an upper end cover. The OCA optical glue is placed between the bottom box and the upper end cover, and is contacted with the side guide wheels at the upper end of the bottom box. Subsequently, the upper end cover is pulled downward under the pulling of an electric push rod, so that the lower pressure wheel presses the OCA optical glue downward together with the side guide wheels, and the OCA optical glue is prevented from being pressed down too much under the action of a movable frame and a spring at the upper end of the lower pressure wheel. Moreover, wrinkles of the OCA optical glue can be reduced under the squeezing of the lower pressure wheel and the side guide wheels, so that the quality of the OCA optical glue is better. After the upper end cover closes the bottom box, heat is generated inside under the action of a heating element inside the upper end cover to perform heating and curing treatment, thereby reducing the dissipation of heat, making the heat more concentrated and the curing effect better.

Description

Technical Field

[0001] The utility model relates to the technical field of optical adhesives, in particular to a curing device for producing OCA optical adhesives. Background Art

[0002] OCA optical glue is a special adhesive mainly used for bonding transparent optical components (such as lenses, etc.). It is required to be colorless and transparent, with a light transmittance of more than 90%, good bonding strength, and can be cured at room temperature or medium temperature, and has small curing shrinkage. During production, the OCA optical glue is mainly made into a substrate-free material, and then a layer of release film is attached to the upper and lower bottom layers in order to be able to cure the OCA optical glue.

[0003] However, most of the current OCA optical adhesive curing equipment uses fans to blow heat onto the OCA optical adhesive to cure it. This method causes the heat to be too dispersed when blowing, and the utilization rate is not high, resulting in poor curing effect. In addition, wind blowing can easily cause the OCA optical adhesive to swing, affecting its quality.

[0004] Therefore, an OCA optical adhesive curing device is proposed. Utility Model Content
