Stripping device for polarizer

Abstract

The invention provides a stripping device for a polarizer. The device comprises a base seat, a screw rod drive mechanism, a base plate carrying platform, a spraying mechanism, a guiding roller, a first roller assembly, a second roller assembly and a material falling platform; the screw rod drive mechanism is arranged on the base seat, and the screw rod drive mechanism comprises a motor, a screw rod connected to the output shaft of the motor, and a slide block which sleeves the screw rod and is in threaded connection with the screw rod; the base plate carrying platform is fixed on the top surface of the slide block; the spraying mechanism is arranged on the base seat through a support; the guiding roller is arranged on the base seat; the first roller assembly is arranged on the base seat through a first supporting frame; the second roller assembly is arranged on the base seat through a second supporting frame; and the material falling platform comprises an inclined section and a horizontal section arranged at the lower end of the inclined section, and the top of the inclined section is flush with the tangent place of two rollers of the second roller assembly. According to the device provided by the invention, in the process of stripping the polarizer by the first roller assembly, the base plate carrying platform performs synchronous motion, so that damage to the polarizer and abase plate is reduced to the minimum extent; and spraying of a solvent facilitates stripping of the polarizer in the stripping process.

Description

technical field [0001] The invention relates to the technical field of display screens, and more specifically, to a polarizer stripping device. Background technique [0002] Polarizer is an important material on display screens, such as LCD screens or OLED screens. The glass substrate of the liquid crystal display is equipped with a polarizer. When the polarizer is attached to the glass substrate, there may be defects such as polarizer attachment deviation, bubbles, dust particles, etc., and the polarizer will be damaged in subsequent processes or tests. Abrasion and scratches may also occur during the process. Therefore, it is necessary to tear off the defective or damaged polarizer from the glass substrate. Generally, the polarizer needs to be peeled off first. Typically, it is manually stripped by a human taking the blade. However, such a method is inefficient, and there are safety risks in operation, and the damage rate of the substrate is high, and residues are easy t...
