In order to solve the above-mentioned problem, the present embodiment provides a film tearing device, which uses a mode of rotating similar to page turning to tear the film 530, so as to reduce the dragging force to the component 510 during the film tearing process, and smoothly tear the film 530 from one side.

According to the film tearing device, the position of the clamping jaw 122 is adjusted to be higher than the position of the absorbing piece 113 through the position adjusting assembly 121 to form avoidance, the position adjusting mechanism drives the clamping mechanism 10 to wholly descend so that the absorbing piece 113 corresponds to the vacuum absorbing portion 531 to absorb, the position adjusting mechanism drives the clamping mechanism 10 to ascend for a certain distance, the absorbing piece 113 absorbs the vacuum absorbing portion (the direct binding force between the vacuum absorbing portion 531 and the part 510 is small, ascending after absorption can be achieved, the vacuum absorbing portion 531 is separated from the part 510), the corner driving piece 112 drives the absorbing piece 113 to rotate, after one side of the attaching portion 532, close to the vacuum absorbing portion 531, is lifted by a certain angle, the position adjusting assembly 121 drives the clamping jaw 122 to close to the absorbing piece 113 to clamp the film 530, and then the position adjusting mechanism drives the clamping mechanism 10 to ascend, so that the whole film 530 is torn off by a similar flip action from the side, compared with the mode that the film 530 is directly torn in the vertical direction after the vacuum absorbing, the film 530 is clamped in an included angle state, the film 530 is clamped, the tearing force is small, the film 530 is equivalent to the tearing action is increased, the deformation of the film 510 is prevented, and the film 510 is torn smoothly, and the deformation is prevented.

Alternatively, as shown in fig. 2 and 3, the first connecting plate 111 includes a driving plate 1111 and a first mounting plate 1112, the driving plate 1111 is connected to the position adjusting mechanism, the position adjusting assembly 121 is mounted on the driving plate 1111, the first mounting plate 1112 is L-shaped, one end of the first mounting plate 1112 is mounted on the driving plate 1111 and forms a mounting space 1113 with the driving plate 1111, and the corner driving member 112 is mounted on the first mounting plate 1112 and located in the mounting space 1113. It will be appreciated that the drive plate 1111 also acts as a mounting member 510 of the clamping mechanism 10 to determine the overall height of the clamping mechanism 10, and that the position adjustment assembly 121 ensures that the relative positions of the clamping jaw 122 and the suction member 113 can be changed.

In other embodiments, the vertical driving element 1212 is mounted on the transmission plate 1111, and the horizontal driving element 1211 is mounted on the output end of the vertical driving element 1212, which is not limited herein.

Preferably, the clamping jaw 122 is adjustable relative to the output end of the position adjustment assembly 121 in a third direction (Y direction in the drawing) perpendicular to the vertical direction and the first direction, respectively. Specifically, as shown in fig. 2, a third waist-shaped hole 1221 extending along the third direction is formed at the mounting end of the clamping jaw 122, the screw penetrates through the third waist-shaped hole 1221 to be connected with the output end of the vertical driving element 1212, the position of the clamping jaw 122 in the third direction can be adjusted by unscrewing the screw, and the position is fixed by fastening the screw. The above arrangement enables the clamping jaw 122 to be adjusted in position in a third direction, facilitating field commissioning, so as to better clamp the centre of the membrane 530.

In order to realize the rotation of the suction member 113, the rotation angle driving member 112 generally adopts a rotation driving motor, but the rotation driving motor has a large volume, and is generally disposed obliquely above the bottom end of the suction member 113 in order to avoid the suction member, and the rotation driving motor drives the suction member 113 to rotate in a direction approaching the clamping jaw 122, but in this rotation mode, because the rotation center is above, a horizontal dragging force is generated during the rotation, a gap is easily generated between the suction member 113 and the vacuum suction portion 531, the membrane 530 is easily separated from the suction member 113, the membrane 530 is easily pulled, and the part 510 is easily damaged.
