[0006] Further, an ion air blower is arranged at the rear end of the rack and faces the positioning jig.

[0007] Further, the limiting block is connected to the top of the positioning jig by screw locking.

[0008] Further, the X-axis linear module, the Y-axis linear module, and the Z-axis linear module are respectively a screw rod and a nut pair driven by a servo motor.

[0009] Further, acrylic sealing plates are arranged on both sides of the rack to form a protective cover.

[0010] The utility model adopts the above technical scheme and has the following beneficial effects:

[0011] 1、The utility model discloses a three-axis system controls the double-jaw pneumatic clamping jaw film tearing action, thereby improving the film tearing efficiency and product precision.

[0012] 2、The utility model discloses an ion fan solves the static problem when tearing the film. BRIEF DESCRIPTION OF DRAWINGS

[0013] The utility model will be further explained in detail in connection with the drawings and specific embodiments:

[0014] Fig. 1 It is whole structure schematic diagram of the utility model;

[0015] Fig. 2 It is structure schematic diagram of positioning fixture. SPECIFIC EMBODIMENT

[0016] As Figs. 1-2 The utility model discloses an electronic paper display film tearing machine, including frame 1, the mesa of frame 1 is equipped with Y axis linear module 2 along the front and back direction is set, be connected with the positioning fixture 3 for positioning electronic paper display on Y axis slider of Y axis linear module 2, positioning fixture 3 is fixed on fixture backing plate, fixture backing plate is fixed on Y axis slider, Y axis linear module 2 drives positioning fixture 3 to move along the front and back direction.The mesa of frame 1 is equipped with X axis linear module 4 along the left and right direction is set, be connected with Z axis linear module 5 on X axis slider of X axis linear module 4, X axis linear module 4 drives Z axis linear module 5 to move left and right.Z axis linear module 5 is connected with double-jaw pneumatic clamping jaw 6 through Z axis slider, and double-jaw pneumatic clamping jaw 6 is fixed on clamping jaw backing block, and clamping jaw backing block is fixed on Z axis slider, and Z axis linear module 5 drives double-jaw pneumatic clamping jaw 6 to move up and down.
