Oblique peeling platform mechanism for full-automatic backlight module assembly machine

Abstract

The invention discloses an oblique peeling platform mechanism for a full-automatic backlight module assembly machine. The oblique peeling platform mechanism comprises a handling manipulator, a supporting unit (66), an actuator (64), a release unit (68), a tape recovery unit (61) and a tape deviation prevention unit (63); the handling manipulator is used for holding and carrying liquid crystal screens; the supporting unit (66) is used for press-fitting, from beneath, an adhesive face of an adhesive tape (67) upwardly onto one side, facing the surface of a film below, of a liquid crystal screen (69); the actuator (64) is used for driving the supporting unit (66) to move towards the opposite side of film press-fitting and return; the release unit (68) is used for releasing the adhesive tape rolled; the supporting unit (66) is disposed on a running path between the release unit (68) and the tape recovery unit (61) below the adhesive tape arranged on the liquid crystal screen; the adhesive face of the adhesive tape faces up. Cylinders are used with a guide rail, the platform mechanism is driven by a module to peel the film, and the platform mechanism is simple and plain; on the premise of functions guaranteed, the cost is lowered, and work efficiency is improved.

Description

technical field [0001] The invention relates to a full-automatic backlight assembly machine, and more specifically relates to a film tearing actuator of a liquid crystal screen. Background technique [0002] The automatic backlight machine is mainly used for the assembly of LCD screen and backlight module. In the working process of the automatic backlight machine, the film on the surface of the LCD screen needs to be torn off, so it is necessary to design a special transport robot, fixing mechanism and film tearing mechanism for the LCD screen. In the automatic backlight machine or automatic backlight assembly machine of the prior art, the conveying manipulator, the fixing mechanism and the film tearing mechanism used for the liquid crystal screen all have hidden dangers in the quality of the produced products. [0003] The problem is that the tearing film platform of the prior art relies on the relative movement between the platforms, which often leads to the problem of in...

AI Technical Summary

Problems solved by technology

[0004] The invention aims to solve the problem of incomplete tearing of the film. It adopts the cooperation of the cylinder and the guide rail, and uses the module to drive the platform to move to realize the tearing of the film. The mechanism is simple and easy to understand. On the premise of ensuring the function, the cost is reduced and the work efficiency is improved.
