[0026] As Figure 1 shown, an automatic film tearing device for separating the film 200 on the workpiece 100, comprising a workbench 1, a carrying mechanism 3 and a driving mechanism 2, the top of the workbench 1 is configured to support a plane, and the support plane is a horizontal plane; the carrying mechanism 3 is rotationally connected to the workbench 1, and the carrying mechanism 3 is used for carrying and limiting the workpiece 100, to ensure that the workpiece 100 is in a stable work station. The driving mechanism 2 is fixedly arranged on the workbench 1, and the driving mechanism 2 has two translational degrees of freedom in the vertical direction and the horizontal direction, and the carrying mechanism 3 is located on the movement path of the output end of the driving mechanism 2, so as to load the workpiece 100 with the film 200 to the carrying mechanism 3. The output end of the carrying mechanism 3 is provided with an openable and closable clamping mechanism 4, when the work station is limited on the carrying mechanism 3, the clamping mechanism 4 clamps the film 200, and when the clamping mechanism 4 moves with the driving mechanism 2, the film 200 is separated from the workpiece 100, so as to realize the work of automatically tearing the film 200 of the workpiece 100, and greatly improve the production efficiency.

[0027] The support plane of the workbench 1 is fixedly provided with a support frame 11, and the driving mechanism 2 is fixedly connected to the support frame 11, and the support frame 11 elevates the driving mechanism 2 to a certain height. The driving mechanism 2 comprises a first guide rail 21 and a second guide rail 22, the first guide rail 21 is fixedly connected to the top of the support frame 11 and arranged horizontally, the second guide rail 22 is slidably connected to the first guide rail 21, and the second guide rail 22 is arranged in the vertical direction, and the second guide rail 22 is slidably connected with an adsorption assembly 23, and the adsorption assembly 23 slides along the length direction of the second guide rail 22, that is, the adsorption assembly 23 moves in the vertical direction. In this embodiment, the first guide rail 21 and the second guide rail 22 are both linear modules, and in other embodiments, the first guide rail 21 and the second guide rail 22 can adopt a ball screw module or a synchronous belt module.

[0028] The adsorption assembly 23 comprises a carrier frame 231 and a plurality of adsorption nozzles 232. The carrier frame 231 is slidingly connected to the second guide rail 22 in the vertical direction. The plurality of adsorption nozzles 232 are fixedly arranged on the bottom of the carrier frame 231. The plurality of adsorption nozzles 232 are arranged in the vertical direction, and the bottoms of the plurality of adsorption nozzles 232 are located on the same horizontal plane, so that the plurality of adsorption nozzles 232 can simultaneously adsorb the workpiece 100. During the transfer process, the workpiece 100 always maintains a horizontal state, and finally the workpiece 100 can be placed on the carrier mechanism 3 in a horizontal state. Specifically, the plurality of adsorption nozzles 232 are each externally connected to a negative pressure machine. The negative pressure machine generates an adsorption force so that the adsorption nozzle 232 can adsorb the workpiece 100. Preferably, the number of adsorption nozzles 232 is four, which adsorb the four corners of the workpiece 100, respectively, to ensure accurate adsorption of the workpiece 100 while reducing the number of adsorption nozzles 232 and reducing costs.

[0029] It should be noted that the film 200 is attached to the top end surface of the workpiece 100, that is, the plurality of adsorption nozzles 232 directly contact the film 200 rather than the workpiece 100. Since the film 200 is adhered to the workpiece 100, the adsorption nozzles 232 can simultaneously adsorb the film 200 and the workpiece 100.

[0030] As shown in Figure 2 and Figure 3 , the clamping mechanism 4 is fixedly arranged on the bottom of the carrier frame 231. In this embodiment, the clamping mechanism 4 is a pneumatic clamping jaw. Specifically, the clamping mechanism 4 comprises a jaw body 41, a first clamping jaw 42 and a second clamping jaw 43. The first clamping jaw 42 and the second clamping jaw 43 are rotatably connected to the jaw body 41 in opposite directions. The first clamping jaw 42 and the second clamping jaw 43 are close to the output end of the driving mechanism 2, and both the first clamping jaw 42 and the second clamping jaw 43 rotate in the vertical direction. Since the workpiece 100 is placed horizontally, the film 200 attached to the workpiece 100 is also arranged horizontally, and the film 200 is machined to form a convex film piece 210 protruding outward from the workpiece 100 during machining, so that the clamping mechanism 4 can clamp the film 200. When the workpiece 100 is placed on the carrier mechanism 3, the clamping mechanism 4 can gradually peel the film 200 from a corner of the workpiece 100.

[0031] As shown in Figure 4As shown, the workbench 1 is provided with a feeding mechanism 5, and the feeding mechanism 5 is located on the moving path of the adsorption assembly 23. The feeding mechanism 5 comprises a feeding table 51, a first feeding column 52 and a second feeding column 53. The feeding table 51 is rotationally connected to the workbench 1. Specifically, the feeding table 51 is rotationally connected to the workbench 1 by a motor drive, so as to realize automatic rotation of the feeding table 51. The first feeding column 52 and the second feeding column 53 are both fixedly connected to the top end face of the feeding table 51. The distance from the first feeding column 52 to the rotation center of the feeding table 51 is equal to the distance from the second feeding column 53 to the rotation center of the feeding table 51, that is, the first feeding column 52 and the second feeding column 53 are symmetrically distributed about the rotation center of the feeding table 51.

[0032] The first feeding column 52 and the second feeding column 53 are both arranged in the vertical direction, and the workpiece 100 is sleeved on the first feeding column 52 or the second feeding column 53 in the vertical direction. Preferably, the first feeding column 52 is fixedly provided with a first anti-rotation rod 54, the first anti-rotation rod 54 is arranged in the vertical direction, and the first anti-rotation rod 54 is attached to the side wall of the first feeding column 52. When the feeding table 51 rotates, the workpiece 100 is prevented from rotating relative to the first feeding column 52, so that the convex diaphragm 210 on each workpiece 100 can be clamped by the clamping mechanism 4. The second feeding column 53 is fixedly provided with a second anti-rotation rod 55, the second anti-rotation rod 55 is arranged in the vertical direction, and the second anti-rotation rod 55 is attached to the side wall of the second feeding column 53. When the feeding table 51 rotates, the workpiece 100 is prevented from rotating relative to the second feeding column 53, so that the convex diaphragm 210 on each workpiece 100 can be clamped by the clamping mechanism 4.

[0033] As shown in the figure, Figure 5 The carrying mechanism 3 and the feeding mechanism 5 are both located on the moving track of the output end of the driving mechanism 2, so as to transfer the workpieces 100 from the feeding mechanism 5 to the carrying mechanism 3 one by one. The carrying mechanism 3 comprises a carrying table 31 and a plurality of carrying pieces 32. The carrying table 31 is rotationally connected to the workbench 1, and the carrying pieces 32 are circumferentially distributed and fixedly connected to the top of the carrying table 31 about the rotation center of the carrying table 31. In this embodiment, the top of the carrying piece 32 is fixedly connected to a plurality of limiting pieces 33, and the hole on the workpiece 100 is inserted into the limiting piece 33, so as to limit the workpiece 100. In other embodiments, the carrying piece 32 can be used to fix the workpiece 100 by adsorption. The workbench 1 is provided with an ejection chute between the carrying mechanism 3 and the feeding mechanism 5, for collecting and processing the torn film 200.

[0034] Principle: the workpiece 100 with the film 200 is manually or automatically fed to the first feeding column 52, that is, the workpiece 100 is sleeved on the first feeding column 52, and the workpiece 100 is stacked in the vertical direction. After the first feeding column 52 is fed, the feeding table 51 is rotated, the first feeding column 52 is located in the grabbing range of the output end of the driving mechanism 2, at this time, the second feeding column 53 is fed to improve the feeding efficiency. The adsorption assembly 23 transfers the workpiece 100 on the first feeding column 52 to a bearing piece 32 on the bearing table 31 one by one, and the clamping mechanism 4 clamps the convex film piece 210 in the process. After the workpiece 100 is limited by the limiting piece 33 of the bearing piece 32, the adsorption assembly 23 no longer adsorbs the workpiece 100, the driving mechanism 2 drives the clamping mechanism 4 to leave the bearing mechanism 3, and at the same time drives the film 200 to separate from the workpiece 100, until the film 200 completely separates from the workpiece 100. When the driving mechanism 2 drives the clamping mechanism 4 to move to the discharge chute, the clamping jaw is opened, the film 200 falls into the discharge chute, and the clamping mechanism 4 tears the film of the next workpiece 100. The bearing table 31 rotates to convey the workpiece 100 with the film removed to the next station.
