AI Technical Summary

Technical Problem

In existing technologies, a large amount of tape is consumed during the film-tearing process, resulting in low utilization and increased production costs.

Method used

A tape tearing mechanism was designed, including a tape assembly, a tearing assembly, and a suction cup assembly. Through the cooperation of a tape feeding power component and a tape feeding roller, the tape can rotate in both directions, reducing tape length waste and improving utilization.

Benefits of technology

By reversing the tape's direction, the length of the tape during the film-tearing process is reduced, increasing tape utilization and lowering production costs.

Abstract

This invention discloses a tape tearing mechanism, including a frame. The frame is equipped with a tape assembly, a tearing assembly, a suction cup assembly, and a polarizer stage. The tape assembly is used to wind tape, with both ends of the tape wound onto the tape assembly. The middle portion of the tape is connected to the tearing assembly. The suction cup assembly is used to feed a polarizer from the polarizer stage onto the tearing assembly, causing it to adhere to the tape, thus bonding the tape to and separating the protective film on the polarizer. The tape assembly includes a tape feeding roller and a tape feeding power component that provides power to it. The tape feeding roller drives the tape to move forward or backward, and the tape feeding power component is a bidirectional power component that provides forward or reverse rotation power to the tape feeding roller.
