Visual Measurement of Film Tear-Off Device

Abstract

This invention relates to a visual measurement device for tearing film with a tear, comprising at least a platform assembly, a rotating device, a tear detection device, a thickness detection device, a tear blowing device, and a tearing device. A substrate with a film can be mounted on the platform assembly. When the film is to be torn off, the tear detection device uses the rotating device to rotate the platform assembly and simultaneously detects the tear position. The thickness detection device then detects the film thickness. After confirming the tear position and film thickness, the tear blowing device blows air into the space between the substrate and the film at the tear, causing part of the film to expand and detach from the substrate. Finally, the tearing device tears off the film. In this way, the substrate is not damaged by the precisely positioned blowing tearing process, and the film can be completely torn off without any residue.
