Device and method for testing adhesive force of film layer

The invention relates to the field of film adhesive force testing, and discloses a film adhesive force testing device and a film adhesive force testing method. The film adhesive force testing device comprises a clamp and a tension meter, the clamp comprises a clamp main body and a clamping block, the clamping block is arranged in a sliding groove of the clamp main body in a sliding mode, and the clamping block and the inner wall of the sliding groove clamp the stripping end of the film. The tension meter is connected with the clamp body. The method for testing the adhesive force of the film layer comprises the following steps: S1, selecting a specified area on a base material, separating the specified area from the film layer in other areas, and recording the width of the film layer in the specified area; s2, one end of the film layer is separated from the base material in the designated area. And S3, the stripping end of the film layer is clamped through a clamp. And S4, pulling the clamp through a tension m
