Description

Film tearing method and film tearing device Technical Field The invention relates to the technical field of film tearing, in particular to a film tearing method and a film tearing device. Background In order to reduce damage to the workpiece during storage and transport, the surface of the workpiece often has a protective film attached thereto, and the protective film on the workpiece needs to be torn off before the workpiece is used. In the related art, a film tearing device is generally adopted to tear off a protective film on a workpiece, the workpiece is grabbed to a positioning area for clamping and positioning, and then the protective film on the workpiece is grabbed and torn off by a manipulator. However, due to the structural problem of the workpiece, the workpiece can deflect under the influence of gravity before the workpiece falls into the positioning area completely, so that the workpiece is difficult to be placed in the positioning area in a preset posture, and the subsequent film tearing effect of the workpiece is further affected. Disclosure of Invention The invention aims to at least solve one of the technical problems in the prior art, and the first aspect of the invention provides a film tearing method, which is used for tearing a film from a workpiece and can improve the film tearing effect of the workpiece.
