Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] like Figure 1 As shown, this embodiment discloses a reverse-edge wrapping film rework device for reworking the film 7 on the surface of the rework plate 2, combined with... Figure 1 , Figure 5 The board 2 is the external touch panel for the buttons of a home appliance. The board 2 includes protrusions 21 located on both sides. Figure 5 In the middle, the protrusion 21 is arranged along the width direction of the plate 2 in the length direction, and the protrusion 21 is provided with a groove 211, which extends through the protrusion 21 in the length direction. For example Figure 1As shown, the groove 211 extends downward along the upper end face of the protrusion 21. The film 7 is bonded to the surface of the plate 2.

The groove 211 is located below the middle of the film edge 71, and the groove 211 penetrates the wall surface of the protrusion 21 bonded to the film edge 71 (i.e., the upper end face of the protrusion 21 mentioned above).
[0033] like Figure 1 The reverse edge wrapping film rework device shown includes a base 1, a guide component 12 is installed on the upper end of the base 1, the guide component 12 is a cylindrical structure, a substrate 13 is slidably connected to the inner wall of the guide component 12, a drive component 11 is installed on the base 1, the drive component 11 is a cylinder, the output end of the drive component 11 is connected to the bottom of the substrate 13, and the drive component 11 can drive the substrate 13 to move up and down.
[0034] The bottom of the plate 2 is inserted into the substrate 13. A movable seat 14 is installed on the top of the base 1. The movable seat 14 is located above the substrate 13. The movable seat 14 moves up and down synchronously with the substrate 13. The movable seat 14 is equipped with a second driving component 141, which is a cylinder. A pressure plate 142 is installed at the output end of the second driving component 141. The pressure plate 142 can move up and down under the drive of the second driving component 141. The pressure plate 142 presses down against the plate 2. The pressure plate 142 and the substrate 13 press the plate 2 up and down to fix the plate 2.
[0035] like Figure 3 As shown, the reverse-wrapping film rework device includes a rod 4, which is rotatable along its own axis. The rod 4 is a long rod structure, comprising a rod part 41 and a rod part 42 located to the right of the rod part 41. The rod part 41 and the rod part 42 are coaxially arranged. A rotating drum 51 is mounted on the rod part 41. The rod part 41 is inserted into the rotating drum 51, and the rotation of the rotating drum 51 drives the rod part 41 to rotate, thereby causing the rod part 42 to rotate. Specifically, a bearing seat 5 is mounted on the outer wall of the rotating drum 51 via a bearing. One gear of a gear pair 52 is mounted on the outer wall of the bearing seat 5, and the gear pair 52 is driven by a motor. Figure 6 As shown, rod part 41 is a square rod.
[0036] like Figure 3 As shown, a rotating cylinder 61 is installed on the side of the rod 42 away from the rod 41. A bearing seat 6 is installed on the outer wall of the rotating cylinder 61 via a bearing. The rotating cylinder 61 rotates synchronously with the rod 42.

Figure 2 As shown, the second part of the rod 42 includes a second wall surface 422, which is arc-shaped, and a first wall surface 421, which is flat. The first wall surface 421 and the second wall surface 422 are the outer walls of the second part of the rod 42.
[0037] As shown in Figure 2 , the rod second part 42 is provided with a slot one 423 on both sides, the length direction of the slot one 423 is arranged along the length direction of the rod second part 42, the slot one 423 is inserted with an insertion rod 43, the insertion rod 43 is a long circular rod structure, the width of the slot one 423 is the same as that of the insertion rod 43. Figure 3 , Figure 4 , the rod second part 42 is provided with a slot two 424 at both ends in the length direction, the slot one 423 is located between the two slot twos 424, the width of the slot one 423 is smaller than that of the slot two 424, and the insertion rod 43 is inserted into the slot two 424. By arranging the slot two 424, the insertion rod 43 can be easily taken out from the slot two 424.
[0038] As shown in Figure 2 , the rod second part 42 can be inserted into the groove 211, as shown in Figure 8 , the plate body 2 moves downward, the upper end of the rod second part 42 can abut against the film edge 71 and support the film edge 71 upward, so that the film edge 71 forms a convex film 711, the convex film 711 is in a convex shape, and part of the film edge 71 is separated from the convex part 21 during the convex process of the convex film 711.
[0039] As shown in Figure 9 , as the rod second part 42 supports the film edge 71 upward, the rod second part 42 gradually moves upward away from the groove 211, when the position of the insertion rod 43 is higher than that of the convex part 21, the insertion rod 43 is pulled out along the radial direction of the rod second part 42, the insertion rod 43 moves along the radial direction of the rod second part 42 to extend into the space between the wall surface of the convex part 21 and the film edge 71, so that the wall surface of the convex part 21 is separated from the film edge 71. When the insertion rod 43 is pulled out of the groove 211, the wall surface one 421 is arranged upward. By extending the insertion rod 43 into the space between the wall surface of the convex part 21 and the film edge 71, the wall surface of the convex part 21 is separated from the film edge 71, which facilitates tearing the film body 7 and prevents the film body 7 from being easily broken.
[0040] As shown in Figure 1 , the reverse edge film rework device further comprises a lifting plate 3, the lifting plate 3 passes through the moving seat 14, and the upper end of the lifting plate 3 is driven by a connecting air cylinder to move up and down. As shown in Figure 1 , Figure 2 , the bottom of the lifting plate 3 is provided with a fixed sleeve 31, the fixed sleeve 31 is slidably connected with a sliding rod 32, the sliding rod 32 can move up and down along the fixed sleeve 31, the bottom of the sliding rod 32 is provided with a pressing rod 34, the sliding rod 32 is sleeved with a spring 33, the upper end of the spring 33 abuts against the fixed sleeve 31, and the lower end of the spring 33 abuts against the pressing rod 34.
[0041] As shown in Figure 2As shown, the pressure rod 34 can move up and down with the lifting plate 3. The pressure rod 34 and the second part of the rod 42 are located on both sides of the upper line of the membrane edge 71, respectively, and abut against the upper and lower sides of the membrane edge 71. When the second part of the rod 42 rotates slowly, the second wall surface 422 rotates slowly. The second wall surface 422 stretches the membrane edge 71 through friction, causing the membrane edge 71 to slowly stretch laterally, resulting in a thinning trend. Simultaneously, the membrane edge 71 and the protrusion 21 exhibit a relative lateral movement trend, loosening the adhesive between the membrane edge 71 and the protrusion 21, facilitating subsequent separation. This also reduces the risk of tearing due to excessive vertical stretching in a short period during the process of the membrane edge 71 bulging upwards to form the convex membrane 711. A rubber pad layer can be installed on the second wall surface 422 as needed to increase the coefficient of friction.
[0042] The rework method of the reverse-edge wrapping film rework device includes the following steps:
[0043] ① Loading: Insert the substrate 13 into the bottom of the plate 2, and move the pressure plate 142 downward to abut against the plate 2 so that the plate 2 is kept fixed.
[0044] ②For example Figure 3 As shown, the installation rod 4 is installed with the first part of the rod 41 inserted into the first rotating cylinder 51, and the second part of the rod 42 passing through the groove 211 and inserted into the second rotating cylinder 61, with the second wall surface 422 facing upwards.
[0045] ③The substrate 13 moves downward to drive the plate 2 to move downward until the wall surface 422 and the pressure rod 34 press against each other to press the film edge 71. The rod 4 rotates slowly to make the second part of the rod 4 rotate slowly, thereby causing the wall surface 422 to rotate and stretching the film edge 71 through friction, so that the film edge 71 is slowly stretched in the lateral direction.
[0046] ④ For example Figure 8 As shown, when the second part of the rod 42 rotates to the state where the second wall 422 faces upward, the plate 2 moves downward, and the second wall 422 supports the membrane edge 71 upward to form a convex membrane 711.
[0047] ⑤ For example Figure 9 As shown, when rod part 42 rotates to the position where wall surface 421 faces upward, plate 2 moves downward, and insert rod 43 extends out of the upper end of groove 211, engaging... Figure 4 Pull out the insertion rod 43 from the slot 2 424. The insertion rod 43 is pulled out in the left and right direction (one of the left and right radial directions of the rod 2 part 42, and in the radial outward direction). When the insertion rod 43 is pulled out, it separates the membrane edge 71 from the protrusion 21.
[0048] ⑥ Remove the entire membrane 7 and then re-coat it.
[0049] The film edge 71 is supported upward by the second rod part 42 to form a convex film 711, the second rod part 42 supports the film edge 71 in the whole width direction, when the convex part 21 is separated from the film edge 71, the stress point is increased, the local breakage of the film edge 71 is reduced, and the operation is facilitated.
[0050] The above only describes the preferred embodiments of the present application, the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical scheme belonging to the idea of the present application belongs to the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application can also be considered as the protection scope of the present application.
