[0002] The display module includes a display panel, a polarizer, a circuit board, etc. During the production process, in order to avoid scratches on the surface of the display panel, a layer of release film is usually attached to its surface. When the display panel needs to be bonded with other components, the release film is torn off.

[0003] In the prior art, the release film is usually torn off with the help of an easy-tear sticker. Specifically, one end of the easy-tear sticker is a sticky end, and the other end is a non-sticky end.

[0027] In the embodiment of the utility model, the film material has a side with a protective film attached with an easy-tear film, the material moving mechanism 300 can move the film material to one side of the first flattening mechanism 200, and the easy-tear film on the film material can be flattened by the first flattening mechanism 200, and the material moving mechanism 300 can move the film material to one side of the first clamping mechanism 100, and the first clamping member 110 can be controlled to move in the horizontal direction by the shifting member 120, and the first clamping member 110 can be controlled to move in the vertical direction by the first lifting member 130, so as to adjust the position of the first clamping member 110 so that The first clamping member 110 can be moved to one side of the film material, and the easy-tear film on the film material can be clamped by the first clamping member 110. When the material taking mechanism moves the film material upward to transfer the film material to other workstations, since the first clamping member 110 clamps the easy-tear film on the film material, the first clamping member 110 can tear off the easy-tear film on the film material, and thus tear off the protective film on the film material. This enables the film tearing action to be completed synchronously when the material taking mechanism takes away the film material, so that the film tearing action can be integrated into the material taking action to save process time, thereby improving production efficiency.

[0028] Specifically, when the material picking mechanism moves the film material upward to transfer the film material to other workstations, the shifting mechanism can synchronously drive the first clamping member 110 to move in a direction away from the film material, so that the first clamping member 110 can cooperate with the material picking mechanism to tear off the easy-to-tear film and the protective film on the film material, so as to further ensure the stability of the film tearing.

[0032] The correction table 400 is used to carry film materials that are not attached with an easy-tear film. The second clamping mechanism 500 is arranged on one side of the correction table 400. When the film material picking arm takes the material from the film material bin and sends it to the correction table 400, the second lifting member 520 can drive the second clamping member 510 to move upward, and the second clamping member 510 can be in an open state to facilitate the second clamping member 510 to clamp the easy-tear film transported by the film material picking arm.

The first clamping driving structure 112 drives the first jaws 111 to move closer to each other so that the first jaws 111 are in a contracted state, thereby allowing the two first jaws 111 to clamp the easy-tear film.
