[0059] In the process of logistics transportation, in order to protect the product surface from scratches or contamination, a protective film is usually attached to the product surface. After transportation, if the product still needs to be processed, the protective film on the product surface needs to be torn off. Currently, the protective film is usually torn off manually. For notebook panels, there are usually extended ears on the inner side of the sliding touchpad of the notebook. The film needs to be torn off from the extended ears, which is cumbersome, time-consuming and labor-intensive, greatly increasing labor costs and labor intensity, and reducing production efficiency.

[0060] In order to solve the above problems, Figure 1-Figure 6 As shown, this embodiment provides a film-tearing device for tearing off a protective film 100 on a product, wherein the product has a notch, such as Figure 1 As shown, the protective film 100 has an extended ear 1001 and clamping parts 1002 located on both sides of the extended ear 1001; the film peeling equipment includes a mounting bracket 1, a bearing mechanism 2, a first clamping assembly 3, a second clamping assembly 4 and a third clamping assembly 5. The mounting bracket 1 extends along the Z-axis direction, the product is fixedly arranged on the bearing mechanism 2, and the bearing mechanism 2 can move along the Y-axis direction to approach or move away from the mounting bracket 1; the first clamping assembly 3 and the second clamping assembly 4 are both slidably arranged on the mounting bracket 1 along the Z-axis direction, the first clamping assembly 3 can extend into the notch and clamp the extended ear 1001, the first clamping assembly 3 moves upward along the Z-axis direction to make the clamping part 1002 peel off the product, and the second clamping assembly 4 can clamp the clamping part 1002; the third clamping assembly 5 can clamp the protective film 100 peeled off the product.

[0061] When using this film tearing device to tear off the protective film 100 on the product, first fix the product on the supporting mechanism 2, and make the side of the product with the protective film 100 attached to it face upwards; make the supporting mechanism 2 move along the Y-axis direction to approach the mounting bracket 1 until the notch of the product is directly opposite to the first clamping component 3, and after the first clamping component 3 moves toward the product along the Z-axis direction to extend into the notch, the supporting mechanism 2 continues to move along the Y-axis direction toward the mounting bracket 1 until the extended ear 1001 of the protective film 100 can be clamped by the first clamping component 3; the first clamping component 3 moves away from the product along the Z-axis direction to pull up the extended ear 1001, thereby peeling off the clamping parts 1002 on both sides of the extended ear 1001 from the product, at this time, the second clamping component 4 can clamp the clamping part 1002; the first clamping component 3 and the second clamping component 4 move away from the product along the Z-axis direction, and at the same time the supporting mechanism 2 moves along the Y-axis direction The protective film 100 peeled off from the product is moved in the Z-axis direction away from the mounting bracket 1, and then the protective film 100 is gradually peeled off from the product. At this time, the protective film 100 peeled off from the product is set at an angle with the protective film 100 still attached to the product. In order to ensure the smoothness of the peeling, the protective film 100 peeled off from the product is clamped by the third clamping component 5, and the third clamping component 5 is moved along the Z-axis direction to change the clamping position of the third clamping component 5. If there are more protective films 100 still attached to the product, the adhesion between the protective film 100 and the product is relatively high. Then the third clamping component 5 is appropriately moved to the lower end position of the protective film 100 peeled off from the product to increase the clamping force; then the first clamping component 3, the second clamping component 4 and the third clamping component 5 move away from the product along the Z-axis direction, and the supporting mechanism 2 continues to move away from the mounting bracket 1 along the Y-axis direction until the protective film 100 is completely peeled off from the product.

[0062] The film-tearing device of this embodiment can automatically complete the film-tearing process, replacing the traditional manual film-tearing method, reducing labor costs and labor intensity, and significantly improving production efficiency. The film-tearing device has a first clamping component 3, which can accurately extend into the notch of the product and clamp the extended ear 1001 of the protective film 100 to ensure the accuracy of the starting point of film-tearing. At the same time, through the coordinated use of the second clamping component 4 and the third clamping component 5, the protective film 100 can be peeled off smoothly, and the film is torn evenly without leaving residue.

[0063] It should be noted that this film tearing device is suitable for products that require internal film tearing, such as notebook panels, etc.; by adjusting the movement parameters and clamping force of the first clamping component 3, the second clamping component 4 and the third clamping component 5, it can be suitable for tearing off protective films 100 of different thicknesses, different materials and different viscosities.

[0064] Specifically, Figure 2 , Figure 3As shown, the bearing mechanism 2 includes a bearing assembly 21 and a first driving member 22. The bearing assembly 21 has a plurality of adsorption holes, and the product can be adsorbed and fixed on the bearing assembly 21. The output end of the first driving member 22 is connected to the bearing assembly 21, and the first driving member 22 can drive the bearing assembly 21 to move along the Y-axis direction. The adsorption and fixation through the plurality of adsorption holes can quickly fix the product, avoiding the clamping marks or damage that may be caused by traditional clamps; the first driving member 22 drives the bearing assembly 21 to move along the Y-axis direction, thereby enabling the product to move along the Y-axis direction.

[0065] In some embodiments, the first driving member 22 is a motor; in other embodiments, the first driving member 22 is a cylinder; in this embodiment, the first driving member 22 is a slide cylinder. It should be noted that any driving structure in the prior art that can drive the bearing assembly 21 to move along the Y-axis direction can be used as the first driving member 22 in this embodiment, and this embodiment does not limit this.

[0066] It should be noted that the vacuum is drawn on the carrier component 21 to generate negative pressure at the adsorption hole to adsorb the product on the carrier component 21. This is a conventional setting in the prior art, and the specific implementation method thereof is not described in detail in this embodiment. In this embodiment, in order to ensure that the product is not pulled up by the tension generated when the film is torn, the negative pressure at the adsorption hole must be less than -80 MPa.

[0067] Specifically, Figure 3 As shown, the bearing mechanism 2 further includes a guide assembly 23, which is used to provide guidance for the movement of the bearing assembly 21. The guide assembly 23 provides precise guidance for the movement of the bearing assembly 21, ensuring that the movement trajectory of the bearing assembly 21 in the Y-axis direction is accurate, which helps to improve the accuracy and consistency of film tearing.

[0068] In this embodiment, the guide assembly 23 includes a slide rail and a slider that are slidably matched. The slide rail extends along the Y-axis direction, and the bearing assembly 21 is connected to the slider or the slide rail.

[0069] Specifically, Figure 3 As shown, the bearing assembly 21 includes a bearing plate 211 and a bearing fixture 212. The bearing plate 211 is connected to the output end of the first driving member 22. The bearing fixture 212 has a plurality of the above-mentioned adsorption holes, and the bearing fixture 212 is detachably connected to the bearing plate 211. When tearing the film, the product is adsorbed and fixed on the bearing fixture 212. By setting the bearing fixture 212 to be detachable, the corresponding bearing fixture 212 can be replaced according to the shape and model of the product, thereby improving the versatility of the film tearing equipment.

[0070] Furthermore, if Figure 3As shown, the carrying mechanism 2 further includes a buffer component 24, which is disposed on at least one side of the carrying fixture 212 along the Y-axis direction. The buffer component 24 includes a buffer member, which can elastically abut against the side of the carrying component 21. During the film tearing process, if the moving speed of the first clamping component 3, the second clamping component 4 and the third clamping component 5 is not synchronized with the moving speed of the carrying fixture 212, the carrying fixture 212 may be impacted, causing the protective film 100 to be easily broken. Therefore, the buffer component 24 is used to absorb the impact force to mitigate the impact force, thereby reducing the risk of the protective film 100 breaking.

[0071] Specifically, Figure 4 As shown, the first clamping assembly 3 includes a first mounting block 31 and two first clamping jaws 32. The first mounting block 31 is slidably arranged on the mounting bracket 1 along the Z-axis direction. The two first clamping jaws 32 are arranged on the first mounting block 31 at intervals along the Z-axis direction. The two first clamping jaws 32 can approach each other to clamp the extended ear portion 1001. By moving the first mounting block 31 along the Z-axis direction, the two first clamping jaws 32 arranged thereon can be located on both sides of the extended ear portion 1001, so that the extended ear portion 1001 can be effectively clamped by the two first clamping jaws 32 approaching each other.

[0072] In this embodiment, if Figure 4 As shown, the first clamping assembly 3 further includes a second driving member 33, which is disposed on the first mounting block 31, and one of the two first clamping jaws 32 is disposed at the output end of the second driving member 33. The second driving member 33 drives one first clamping jaw 32 to move toward or away from the other first clamping jaw 32 to clamp or release the extension ear portion 1001.

[0073] In some embodiments, the second driving member 33 is a motor; in other embodiments, the second driving member 33 is a cylinder; in this embodiment, the second driving member 33 is a slide cylinder. It should be noted that any driving structure in the prior art that can drive one first clamping jaw 32 to move toward or away from another first clamping jaw 32 can be used as the second driving member 33 in this embodiment, and this embodiment does not limit this.

[0074] Specifically, the two first clamping jaws 32 are provided with staggered meshing teeth on opposite sides thereof, so that the two first clamping jaws 32 can stably clamp the extension ear 1001, and can reduce the adhesive on the protective film 100 from adhering to the first clamping jaws 32, thereby reducing the need for cleaning the first clamping jaws 32. In this embodiment, the meshing teeth are sawtooth-shaped or pyramid-shaped.

[0075] In this embodiment, if Figure 2 , Figure 3As shown, there are two first clamping assemblies 3, and the two first clamping assemblies 3 are spaced apart along the X-axis direction. The two first clamping assemblies 3 jointly clamp the extended ear 1001 to achieve stable clamping support for the extended ear 1001, which helps to reduce the film tearing deviation or damage caused by uneven tension of the protective film 100.

[0077] The two second clamping assemblies 4 are respectively used to clamp the two clamping parts 1002. The second clamping assemblies 4 can be slidably arranged on the mounting bracket 1 along the Z-axis direction through the third driving member 41, so that the two second clamping jaws 44 can move to face the clamping part 1002; the third driving member 41 can drive the two second clamping jaws 44 to move along the Y-axis direction, so that the two second clamping jaws 44 can move to the two sides of the clamping part 1002, and can be rotatably arranged on the mounting plate 42 through the second mounting block 43, so that the two second clamping jaws 44 can be rotated to be level with the clamping part 1002, thereby making the two second clamping jaws 44 approach each other to clamp the clamping part 1002.

[0078] In some embodiments, the third driving member 41 is a motor; in other embodiments, the third driving member 41 is a cylinder; in this embodiment, the third driving member 41 is a slide cylinder. It should be noted that any driving structure in the prior art that can drive the mounting plate 42 to move along the Y-axis direction can be used as the third driving member 41 in this embodiment, and this embodiment does not limit this.

[0079] Specifically, the two second clamping jaws 44 are provided with staggered meshing teeth on opposite sides thereof, so that the two second clamping jaws 44 can stably clamp the clamping portion 1002, and can reduce the adhesive on the protective film 100 from adhering to the second clamping jaws 44, thereby reducing the need for cleaning the second clamping jaws 44. In this embodiment, the meshing teeth are sawtooth-shaped or pyramid-shaped.

[0080] In this embodiment, if Figure 5As shown, the second clamping assembly 4 further includes a fifth driving member 45, which is disposed on the second mounting block 43, and one of the two second clamping jaws 44 is disposed at the output end of the fifth driving member 45. The fifth driving member 45 drives one second clamping jaw 44 to move toward or away from the other second clamping jaw 44 to clamp or release the clamping portion 1002.

[0081] In some embodiments, the fifth driving member 45 is a motor; in other embodiments, the fifth driving member 45 is a cylinder; in this embodiment, the fifth driving member 45 is a slide cylinder. It should be noted that any driving structure in the prior art that can drive one second clamping jaw 44 to move toward or away from another second clamping jaw 44 can be used as the fifth driving member 45 in this embodiment, and this embodiment does not limit this.

[0082] Specifically, Figure 6 As shown, the third clamping assembly 5 includes a fourth driving member 51, a third mounting block 52 and two third clamping jaws 53.

The two third clamping jaws 53 can approach each other to clamp the partial protective film 100 peeled off from the product.

[0083] The third clamping assembly 5 can be slidably arranged on the mounting bracket 1 along the Z-axis direction through the fourth driving member 51, so that the two third clamping jaws 53 can move to the corresponding position of the partial protective film 100 peeled off from the product.
