Description
Technical Field
[0001] The utility model relates to the technical field of polaroids, in particular to a clamping device for detecting polaroids. Background Art
[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal displays must rely on polarized light. All liquid crystals have two polarizers in front and back that are tightly attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about one millimeter. It is an indispensable component in liquid crystal imaging technology. Polarizers need to be inspected after production to check their surface quality and whether they contain impurities or bubbles. Currently, there are generally two ways to inspect polarizers. One is manual visual inspection and the other is machine vision inspection. Manual inspection is inefficient and is also affected by the subjective consciousness of the inspectors. The inspection results are not objective enough. Machine vision inspection uses a camera and a computer to inspect polarizers. The inspection results are more objective and the inspection efficiency is high.
[0003] Publication No. CN212083255U discloses a polarizer inspection device. A feed assembly delivers polarizers to a support assembly, and a pressing device flattens the polarizers. This allows the camera to capture the flat polarizers, preventing the computer from incorrectly identifying and judging the polarizer's quality due to curved or uneven polarizers. This polarizer inspection device can flatten polarizers, thereby effectively improving polarizer inspection accuracy. However, this patent still has the following problems in actual use:
[0004] Although the polarizer detection device conveys the polarizer to the supporting assembly through the feeding assembly and then flattens the polarizer through the pushing device, so that the camera can capture the flat polarizer, it is unable to clamp defective polarized lenses. As a result, when defective polarized lenses are detected, the detection needs to be stopped and the defective polarized lenses need to be removed. The operation is cumbersome and affects the efficiency of polarized lens detection.
[0005] Therefore, a clamping device for polarizer detection is proposed to solve the above-mentioned problems. Utility Model Content
