Slant film tearing platform with anti-falling mechanism on full-automatic backlight assembly machine

Abstract

The invention discloses a slant film tearing platform with an anti-falling mechanism on a full-automatic backlight assembly machine. The slant film tearing platform with the anti-falling mechanism on the full-automatic backlight assembly machine comprises a liquid crystal display carrying mechanical hand, a propping unit (66) which presses the bonding surface of tapes (67) upwards onto one side of a thin film surface from a lower position and an actuating mechanism which realizes film tearing (64); the slant film tearing platform with the anti-falling mechanism on the full-automatic backlight assembly machine further comprises a release unit (68) which is used for a roll-shaped tapes and a tape recycling unit (61); the anti-falling mechanism-polished shaft supporting rod (65) provided by the invention is arranged in the travelling track of tapes between the release unit and the tape recovery unit and is positioned in a position that the film of the liquid crystal display is torn; the anti-falling mechanism solves the problem that during the recycling process of the tapes, interferences with other components are avoided; the tapes are prevented from winding and binding; the anti-falling mechanism is simple and is convenient to regulate, so that the entire equipment is enabled to be more perfect and operations to be more smooth; besides, the match between an air cylinder and a guide rail is adopted; a module is utilized, so as to drive the platform to move and realize film tearing; the anti-falling mechanism is simple and easy to understand; under the premise of ensuring functions, the cost is lowered and the working 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...
