A polarizer removal device for mobile phone screen after patching

Abstract

The invention discloses a polarizer removing device for a mobile phone screen after pasting, which comprises an upper base, a lower base, a vertical support wall, and two rows of vertical transmission rollers. A hollow sheet removal suction roller is provided between the support walls, and both ends of the sheet removal suction roller are provided with a limit roller column and a horizontal rotation shaft. A sleeve is set on the horizontal rotation shaft, and a U-shaped limit seat is fixed at the bottom of the rectangular through groove. The horizontal rotation shaft and the sleeve are set in the U-shaped limit seat, and a spring is provided between the sleeve and the upper inner wall of the rectangular channel. The limit roller and the axis of the horizontal rotation shaft are jointly provided with a long air hole, and the long air hole There is a long hollow air pipe inside, the vacuum machine is connected with the long hollow air pipe, the lower base and the upper base are equipped with a stepping motor, and the pulley on the stepping motor is connected with the left pulley of the film removing suction roller through an elastic belt. connection, the present invention can remove the polarizers on both sides of the scrapped mobile phone screen, and the mobile phone screen can be reused.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal panel manufacturing, and in particular, the invention relates to a device for removing a polarizer of a mobile phone screen after pasting. Background technique [0002] In the prior art, a polarizer needs to be pasted on the collection screen, but when the polarizer is pasted, the pasted polarizer will have various flaws and problems. If the polarizer is not removed, the first step is to continue Later production operations will cause spots and other defects on the screen. Second, the mobile phone screen and polarizer may be scrapped together. However, if the defective polarizer is removed, a good mobile phone screen will be cleaned after a series of cleaning operations. It can be used again, but manual operation will be more troublesome to remove the attached polarizer, so we need a device that can automatically remove the attached polarizer on the screen of the mobile phone without damagi...

[0002] In the prior art, a polarizer needs to be pasted on the collection screen, but when the polarizer is pasted, the pasted polarizer will have various flaws and problems. If the polarizer is not removed, the first step is to continue The production operation in the future will cause spots and other defects on the screen. Second, the mobile phone screen and polarizer may be scrapped together. However, if the defective polarizer is removed, a good mobile phone screen will be cleaned after a series of cleaning operations. It can be used again, but manual operation will be more troublesome to remove the attached polarizer, so we need a device that can automatically remove the attached polarizer on the mobile phone screen without damaging the mobile phone screen
