Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive strip release film peeling, and particularly relates to an adhesive strip peeling mechanism. Background Art

[0002] The current principle of strip peeling is to drag the front and rear ends of the strip release film in opposite directions at the same time, so that the release film maintains a certain tension, ensuring that the release film and the strip are flat, and at the same time drag the release film forward to bend the release film through the sharp corners of the jig. The strip on the release film relies on its own rigidity, and when the release film is bent by the sharp corners of the jig, it gradually separates from the release film, completing the peeling action. The main peeling methods currently include the material connection platform type (the strip and the release film move forward at the same time, the strip is peeled and gradually moved to the material connection platform) and the backward type (the position of the strip remains unchanged, the material picking jig is moved to the material picking position, the stripping jig is withdrawn, the strip is gradually peeled and directly adsorbed to the material picking jig). The material connection platform type and the backward type stripping method have size restrictions on the width and length of the strip, and cannot peel off strips that are too long or too narrow. Based on this, we propose a device that can easily and quickly peel off the release film of large-sized and long strips. Utility Model Content
