AI Technical Summary

Technical Problem

When removing the release film from the adhesive backing of flat cables, the existing technology uses inconsistent tearing techniques by different workers, resulting in inconsistent tension and angle, which can easily damage the cable.

Method used

Design a film-tearing device, including an adsorption component, a support component, a clamping component, and a transfer component. By cooperating with the clamping component and the transfer component, the angle and tension during film tearing can be adjusted to ensure a uniform film tearing process and avoid damage to the workpiece.

Benefits of technology

This method achieves uniformity in tension and angle during the film-tearing process, reducing the risk of workpiece damage and improving film-tearing efficiency and success rate.

Abstract

This application discloses a film-tearing device, including an adsorption member, a support member, a clamping assembly, and a transfer member. The support member includes a support surface for abutting the side of the workpiece away from the adsorption member. The clamping assembly includes a rotating member and a clamping member. The clamping member clamps the protective film, and the rotating member is connected to the clamping member and drives the clamping member to rotate about a first direction away from the adsorption member, causing the clamped portion of the protective film to be inclined relative to the workpiece, with the first direction parallel to the support surface. The transfer member is connected to the clamping assembly and drives the clamping assembly to move closer to the adsorption member along the film-tearing direction to tear off the protective film. The film-tearing device tears off the protective film attached to the workpiece through the cooperation of the transfer member and the clamping assembly. Furthermore, the transfer member and the rotating member can adjust the angle and the pulling force acting on the protective film during tearing, ensuring that the pulling force and angle are the same when tearing off each sheet of protective film.
