[0055] The conveying assembly 40 is arranged on the punch 60, so that the conveying assembly 40 moves together with the isolation film 30 along with the punch 60 in the first direction z, so that the isolation film 30 is stationary relative to the stamping piece 20 in the first direction z when the stamping piece 20 stamps the workpiece, and the isolation film 30 is kept close to the stamping piece 20 when the stamping piece 20 stamps the workpiece, so as to reduce the deformation amount of the isolation film 30.

The axis of rotation of the second limiting member 46 relative to the second bracket 44 passes through the bottom of the second groove 462, so that the second limiting member 46 rotates about the bottom of the second groove 462 relative to the second bracket 44 to adjust the orientation of the opening of the second groove 462.

[0085] like Figure 4 As shown, when the opening of the second groove 462 is vertically upward along the first direction, the second scroll 42 is held at the bottom of the second groove 462 by gravity to prevent the second scroll 42 from coming out of the second groove 462.

[0086] Thus, the first spool 41 is detachably connected to the first bracket 43, and the second spool 42 is detachably connected to the second bracket 44, so as to facilitate the removal of the first spool 41 and the second spool 42 to replace the separator 30.

[0087] In some embodiments provided in this application, the first limiting member 45 is provided with a third groove 452, the third groove 452 extends radially along the first scroll 41, and the first limiting member 45 can rotate circumferentially relative to the first bracket 43 along the first scroll 41 so that the orthographic projection of the first groove 431 in the axial direction of the first scroll 41 can be located inside the orthographic projection of the third groove 452 in the axial direction of the first scroll 41.

[0088] like Figure 4 (a) and Figure 4As shown in (b) of FIG. 4, the bottom of the third slot 452 and the bottom of the first slot 431 are arranged in correspondence in the third direction y, and the axis of rotation of the first limiting member 45 relative to the first support 43 coincides with the axis of rotation of the first roller 41 relative to the first support 43, so that the bottom of the third slot 452 always coincides with the bottom of the first slot 431 in the third direction y.

[0089] As shown in (a) of FIG. 4, the first limiting member 45 can be rotated to the third slot 452 intersecting the first slot 431, so that the wall of the third slot 452 is blocked between the opening of the first slot 431 and the bottom of the first slot 431, thereby avoiding the first roller 41 from being detached from the bottom of the first slot 431. ​ As shown in (b) of FIG. 4, the first limiting member 45 can be rotated to the third slot 452 extending in the same direction as the first slot 431, so that the first roller 41 can be detached from or assembled to the first slot 431 along the third slot 452 and the first slot 431.

[0090] As shown in (a) of FIG. 4, the first limiting member 45 can be rotated to the third slot 452 intersecting the first slot 431, so that the wall of the third slot 452 is blocked between the opening of the first slot 431 and the bottom of the first slot 431, thereby avoiding the first roller 41 from being detached from the bottom of the first slot 431. ​ As shown in (b) of FIG. 4, the first limiting member 45 can be rotated to the third slot 452 extending in the same direction as the first slot 431, so that the first roller 41 can be detached from or assembled to the first slot 431 along the third slot 452 and the first slot 431.

[0091] In some embodiments provided in the present application, the first limiting member 45 comprises a first handle 451, and the second limiting member 46 comprises a second handle 461.

[0092] The first handle 451 extends to the outside of the first support 43 in the radial direction of the rotation of the first limiting member 45 relative to the first support 43, so as to facilitate the rotation of the first limiting member 45 by the user, and the second handle 461 extends to the outside of the second support 44 in the radial direction of the rotation of the second limiting member 46 relative to the second support 44, so as to facilitate the rotation of the second limiting member 46 by the user.

[0093] The stamping device 100 provided in the present application is used in work, and the workpiece is positioned and installed on the side of the workbench 10 facing the stamping piece 20. The stamping piece 20 is connected with the conveying device 40, and the isolating film 30 is arranged in the conveying device 40. The isolating film 30 extends between the workpiece and the stamping piece 20. When the stamping piece 20 is pressed towards the workpiece in the first direction z, the isolating film 30 moves with the stamping piece 20 in the first direction z and is isolated between the surface of the stamping piece 20 and the surface of the workpiece, so as to avoid the part of the workpiece cut by the stamping piece 20 from adhering to the surface of the stamping piece 20.

[0094] After the stamping piece 20 performs a stamping action on the workpiece, part of the isolating film 30 between the stamping piece 20 and the workpiece may be damaged or stretched, thereby affecting the isolation effect of the part of the isolating film 30 between the stamping piece 20 and the workpiece.

[0095] The conveying assembly 40 can convey the isolation film 30 in the second direction x, so that another part of the isolation film 30 is moved to between the punch 20 and the workpiece in the second direction x, so that the part of the isolation film 30 between the punch 20 and the workpiece can always keep a better isolation effect.

[0096] The second driving member 75 can adjust the position of the isolation film 30 in the third direction y relative to the punch 20, so that another part of the isolation film 30 is moved to between the punch 20 and the workpiece in the third direction y, so that the part of the isolation film 30 between the punch 20 and the workpiece can always keep a better isolation effect, and improve the utilization of the isolation film 30.

[0097] When the punch 20 is replaced, the conveying assembly 40 is driven by the first driving member 72 to move in the first direction z together with the isolation film 30, so that the isolation film 30 is separated from the surface of the punch 20 on the side facing the worktable 10, or the isolation film 30 is always tightly attached to the surface of the punch 20 on the side facing the worktable 10.

[0098] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
