Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 4 The present invention provides an embodiment of a novel automatic film-tearing mechanism, comprising a film-tearing platform 1, a film-tearing arm 2, and a waste film collection box 3. The film-tearing platform 1 includes a transport arm Y-axis 103, with a first mounting plate 102 slidably disposed on the upper end of the transport arm Y-axis 103. A film-tearing workbench 101 is fixedly disposed on the upper end of the first mounting plate 102 by threads. The waste film collection box 3 includes a storage box 301, which can store waste film. Handles 302 are fixedly disposed at both the front and rear ends of the storage box 301.

[0025] Specifically, this device consists of a film-tearing platform 1, a film-tearing arm 2, and a waste film collection box 3. The film-tearing platform 1 facilitates the transport of products to the area below the film-tearing arm 2. The film-tearing arm 2 descends to tear the film, and after completion, the product is thrown into the waste film collection box 3. The transport arm Y-axis 103 facilitates the adjustment of the position of the film-tearing worktable 101. The first mounting plate 102 facilitates the installation of the film-tearing worktable 101. The storage box 301 facilitates the storage and collection of waste film, and the carrying block 302 facilitates the handling of the storage box 301.

[0026] Reference Figure 1-4 The film-tearing arm 2 includes two support frames 207. A second mounting plate 209 is fixedly mounted on the upper end of each support frame 207. An arm X-axis 203 is fixedly mounted on the upper front end of the second mounting plate 209. An arm Z-axis 205 is threadedly fixed to one side of the front end of the arm X-axis 203. A third mounting plate 211 is threadedly fixed to the lower front end of the arm Z-axis 205. A film-clamping cylinder 20 is threadedly fixed to the lower front end of the third mounting plate 211. 4. A film pressing cylinder 201 is fixedly installed on the other side of the upper end of the film clamping cylinder 204. A film lifting roller 202 is rotatably installed on the other side of the lower end of the film clamping cylinder 204 via a rotating shaft. An induction fiber optic cable 206 is fixedly installed on one side of the lower end of the film clamping cylinder 204. Multiple fixing holes 212 are opened on both sides of the front end of the arm X-axis 203. Fixing plates 208 are fixedly installed on the lower ends of the two support frames 207. Mounting holes 210 are opened at the four corners of the upper end of the two fixing plates 208.

[0027] Specifically, the support frame 207 is made of high-strength aluminum alloy, which is beneficial for the installation of the film-tearing arm 2 of this device and improves the stability of the device during use. The connection between the second mounting plate 209 and the support frame 207 adopts a combination of welding and bolt connection to ensure connection strength while facilitating disassembly and maintenance in the future. Both the X-axis 203 and the Z-axis 205 of the arm are equipped with high-precision servo motors, which can achieve precise position control. The motors and shafts are connected by couplings to reduce transmission errors. The film clamping cylinder 204 is selected with a suitable stroke and stable clamping force. Its chuck part is made of special rubber material, which can ensure the clamping effect of the film without damaging the film. The pressing height and pressure of the film pressing cylinder 201 can be adjusted according to different types of films and products. The film lifting roller 202 is made of polyurethane material with a smooth surface and moderate hardness, which can effectively prevent scratching the film. The sensing fiber optic 206 has high sensitivity and anti-interference ability, which can accurately detect the position and status of the film. The mounting hole 210 on the fixing plate 208 facilitates connection with other equipment or fixed brackets.

[0028] Working principle: This device consists of a film-tearing platform 1, a film-tearing arm 2, and a waste film collection box 3. The film-tearing platform 1 transports the product to the area below the film-tearing arm 2, and the film-tearing arm 2 descends to tear the film. After completion, the product is thrown into the waste film collection box 3. The film-tearing arm of this device is equipped with a variety of high-precision components, such as high-precision servo motors for the X and Z axes to achieve precise position control. The film-lifting roller 202, the film-clamping cylinder 204, and the film-pressing cylinder 201 work together to accurately lift, clamp, and tear off the protective film. Moreover, the various actions are closely coordinated and smooth during the film-tearing process, which can efficiently complete the film-tearing task and greatly improve production efficiency.

[0029] Secondly, the film-tearing arm 2 consists of components such as a film-pressing cylinder 201, a film-lifting roller 202, an arm X-axis 203, a film-clamping cylinder 204, an arm Z-axis 205, and a sensing fiber optic 206. During film tearing, the transport arm Y-axis 103 is activated to move the film-tearing worktable 101 to below the film-pressing cylinder 201. The film-pressing cylinder 201 presses down, the film-lifting roller 202 presses the film, and the arm X-axis 203 moves forward, with the film-lifting roller 202 removing the protective film from the product. The protective film is clamped by the clamping cylinder 204, and the X-axis of the arm 203 continues to move in coordination with the Z-axis of the arm 205 to tear the protective film from the product. After tearing the film, the X-axis of the arm 203 continues to move to the upper end of the waste film collection box 3, the clamping cylinder 204 opens, and the pressing cylinder 201 moves up and down to knock the film off the clamping cylinder 204. The clamping cylinder 204 is equipped with a sensing fiber optic cable 206 to sense whether the film is clamped and whether the film is polished.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
