Description

Mucosa mechanism and film tearing machine using it

technical field

The present invention relates to the technical field of tearing film, in particular, refers to a mucous membrane mechanism and a film tearing machine using it.

Background technique

The polarizer attached to the surface of the LCD panel has a protective film to protect the polarizer from being damaged by collision during operation. On the other hand, it also prevents particles or dust in the air from falling on the polarizer in the working environment on-chip problem. The traditional method of tearing the film of the polarizer uses manual tearing, which is inefficient, and the cleanliness of the working environment of manual tearing of the film is relatively low. After the protective film of the polarizer is torn off, the particles suspended in the air Or dust is easy to fall on the polarizer, resulting in poor quality of the LCD panel.

In the existing film tearing machine, its mucous membrane mechanism is generally wound on the mucous membrane roller with tear-off tape, and the two ends of the tear-off tape are respectively wound on the feed pulley and the take-up pulley, and a number of tape guide idlers are set to constrain the tape delivery. The take-up pulley will use a torque motor, and the hair pulley will be provided with a brake mechanism. Its disadvantages are: the tape feeding mechanism is complicated, the tape is easy to break, the mucous membrane mechanism is bulky, there are many processing parts, and the cost is high.
