OCA detection device

Abstract

The invention provides an OCA detection device. The OCA detection device comprises a rotary table, five stations are arranged along the periphery of the rotary table, and the five stations are correspondingly provided with a feeding unit, a first detection unit, a second detection unit, a third detection unit and a discharging unit; the rotary table comprises a rotating disc and a carrier uniformly distributed on the periphery of the disc, the carrier extends along the radial direction of the disk from the edge of the disk to the direction away from the center of the disk; the first detectionunit comprises a first camera and a first surface light source, the first camera is located above the rotary table, the first surface light source is located below the rotary table; the second detection unit comprises a second camera capable of scanning along the radial line of the rotary table and a coaxial light source, the coaxial light source is arranged above the rotary table, and the secondcamera is arranged above the coaxial light source; and the third detection unit comprises a third camera and a second surface light source, the second surface light source is arranged above the rotarytable, and the third camera is arranged above the second light source. The testing device is used for detecting the defects of glue shortage, bubble, concave point and convex point, deformation and being crushed of OCA products.

Description

technical field [0001] The invention relates to the technical field of detection equipment, and is particularly suitable for OCA detection equipment. Background technique [0002] OCA (Optically Clear Adhesive) is a special adhesive for bonding transparent optical components (such as lenses, etc.), which requires colorless transparency, light transmittance above 90%, good bonding strength, and can be cured at room temperature or medium temperature , and has the characteristics of small curing shrinkage. OCA optical adhesive is one of the important raw materials for touch screens. It is made of optical acrylic adhesive without substrate, and then laminated with a layer of release film on the upper and lower layers. It is a double-sided adhesive tape without substrate material. The common defects of OCA are lack of glue, bubbles, bumps, deformation and crushing. These defects will affect the light transmission effect of OCA. In actual production, it is required to quickly det...

AI Technical Summary

Problems solved by technology

The common defects of OCA are lack of glue, air bubbles, bumps, deformation and crushing. These defects will affect the light transmission effect of OCA. In actual production, it is required to quickly detect whether OCA has the above defects.
