Description

Technical Field

[0001] The present invention relates to the technical field of reverse edge wrapping film production equipment, and more specifically, to a reverse edge wrapping film rework device and method. Background Art

[0002] In the current production process of reverse edge wrapping films, the outer film body forms a reverse edge through two bends. When quality defects occur, the film needs to be torn. Since the film is tightly bonded to the decorative board, tearing the film from a local position easily causes the film body to break, making the operation difficult and affecting the production rhythm. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a reverse edge wrapping film rework device and method, which reduce the phenomenon of film body breakage and improve the operation convenience.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: A reverse edge wrapping film rework device is used for reworking the film body on the surface of a plate body. The plate body includes a convex portion, and the film body includes a film edge. The wall surface of the convex portion is bonded to the film edge. The convex portion is provided with a groove that penetrates the wall surface on the side where the convex portion is bonded to the film edge; it includes a second rod part that can be inserted into the groove. When the plate body moves downward, the upper end of the second rod part can abut against the film edge and push the film edge upward; the second rod part is provided with a first groove, and the length direction of the first groove is along the length direction of the second rod part. An insertion rod is inserted into the first groove. As the second rod part pushes the film edge upward, the second rod part gradually leaves the groove. When the position of the insertion rod is higher than the convex portion, the insertion rod moves radially outward along the second rod part and leaves the first groove, and extends between the wall surface of the convex portion and the film edge, so as to separate the wall surface of the convex portion from the film edge.

[0005] The present invention is further configured such that the second rod part can rotate along its own axis. The second rod part includes a second wall surface, and the second wall surface is arc-shaped. It further includes a pressing rod that can move up and down. The pressing rod and the second rod part are respectively located on both sides of the upper line of the film edge. The pressing rod and the second rod part respectively abut against the upper and lower sides of the film edge, and the second wall surface rotates to stretch the film edge.

[0006] The present invention is further configured such that the second rod part includes a first wall surface, and the first wall surface is a plane.

[0007] The present invention is further configured to further include a base and a pressing plate. The bottom of the plate body is inserted into the base, and the pressing plate can move up and down. The pressing plate is located above the base, and the pressing plate and the base can tightly press the plate body up and down.

[0008] The present invention is further configured such that the width of the first groove is the same as that of the insertion rod. The two ends of the second rod part in the length direction are provided with second grooves. The first groove is located between the two second grooves, and the width of the first groove is smaller than that of the second grooves.

[0009] The present invention is further configured to include a rod body, which includes a first rod part and a second rod part. The first rod part and the second rod part are coaxially arranged. A first rotating cylinder is installed on the first rod part, and the first rod part is inserted into the first rotating cylinder. The rotation of the first rotating cylinder drives the rotation of the first rod part, so as to drive the rotation of the second rod part.

[0010] The present invention is further configured such that a second rotating cylinder is installed on the side of the second rod part away from the first rod part, and a second bearing seat is installed on the outer wall of the second rotating cylinder through a bearing. The second rotating cylinder rotates synchronously with the second rod part.

[0011] The present invention is further configured such that when the insertion rod leaves the first groove, the wall surface one is arranged upward.

[0012] The present invention also adopts the following technical solution: A rework method for a reverse edge wrapping film rework device, including the following steps:

[0013] ① Loading: Fix the plate body in place;

[0014] ② The second rod part passes through the groove;

[0015] ③ The plate body moves downward, and the second wall surface pushes the film edge upward to form a convex film; <ocke;

[0014] ② The second rod part passes through the groove;

[0015] ③ The plate body moves downward, and the second wall surface pushes the film edge upward to form a convex film;

[0016] ④ The plate body moves downward, the insertion rod extends out of the upper end of the groove, and the insertion rod is pulled out from the second groove. When the insertion rod is pulled out, the film edge is separated from the raised part;

[0017] ⑤ Remove the entire film body and then re-cover the film.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The film edge is pushed upward by the second rod part to form a convex film. The second rod part forms a supporting force on the film edge in the entire width direction. When the raised part is separated from the film edge by debonding, the number of force application points is increased, and the phenomenon of local disconnection of the film edge during separation is reduced, which is convenient for operation.

[0020] 2. When the second rod part rotates slowly, the second wall surface rotates slowly. The second wall surface stretches the film edge, so that the film edge is slowly stretched horizontally, and the film edge shows a thinning trend. The film edge is stretched horizontally, and at the same time, there is a relative horizontal movement trend between the film edge and the raised part, so that the adhesive between the film edge and the raised part becomes loose, which is convenient for subsequent separation. And it can reduce the phenomenon that the film edge is easily torn due to too large vertical stretching amplitude in a short time during the process of the film edge bulging upward to form a convex film.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, this embodiment discloses a device for reworking the edge film, which is used to rework the film 7 on the surface of the plate 2, combined with Figure 1 、 Figure 5 The plate body 2 is the outer touch panel of the key of the home appliance, and the plate body 2 includes raised parts 21 on both sides. Figure 5 In the embodiment, the length direction of the protrusion 21 is arranged along the width direction of the plate body 2, and the protrusion 21 is provided with a groove 211, and the groove 211 passes through the protrusion 21 along the length direction. Figure 1As shown in the figure, the groove 211 extends downward and recessed along the upper end surface of the convex portion 21. The surface of the plate body 2 is bonded with a film body 7. The film body 7 includes a film edge 71, and the wall surface of the convex portion 21 is bonded to the film edge 71. The groove 211 is located below the middle of the film edge 71, and the groove 211 penetrates through the wall surface (i.e., the upper end surface of the convex portion 21 mentioned above) of the side where the convex portion 21 is bonded to the film edge 71.

[0033] As Figure 1 shown, the reverse edge wrapping film rework device includes a base 1. A guiding component 12 is installed at the upper end of the base 1. The guiding component 12 is of a cylindrical structure. A substrate 13 is slidably connected to the inner wall of the guiding component 12. The base 1 is installed with a first driving component 11. The first driving component 11 is a cylinder. The output end of the first driving component 11 is connected to the bottom of the substrate 13. The first driving component 11 can drive the substrate 13 to move up and down.

[0034] The bottom of the plate body 2 is inserted into the substrate 13. A moving seat 14 is installed at the top of the base 1. The moving seat 14 is located above the substrate 13. The moving seat 14 moves up and down synchronously with the substrate 13. The moving seat 14 is installed with a second driving component 141. The second driving component 141 is a cylinder. A pressing plate 142 is installed at the output end of the second driving component 141. The pressing plate 142 can move up and down under the drive of the second driving component 141. The pressing plate 142 presses downward against the plate body 2. The pressing plate 142 and the substrate 13 press the plate body 2 tightly up and down to fix the plate body 2.

[0035] As Figure 3 shown, the reverse edge wrapping film rework device includes a rod body 4. The rod body 4 can rotate along its own axis. The rod body 4 is of a long rod structure. The rod body 4 includes a first rod portion 41 and a second rod portion 42 located on the right side of the first rod portion 41. The first rod portion 41 and the second rod portion 42 are coaxially arranged. A first rotating cylinder 51 is installed on the first rod portion 41. The first rod portion 41 is inserted into the first rotating cylinder 51. The rotation of the first rotating cylinder 51 drives the first rod portion 41 to rotate, so that the second rod portion 42 rotates. Specifically, a bearing seat 5 is installed on the outer wall of the first rotating cylinder 51 through a bearing. One of the gears of a gear pair 52 is installed on the outer wall of the bearing seat 5. The gear pair 52 is driven by a motor. As Figure 6 shown, the first rod portion 41 is a square rod.

[0036] As Figure 3 shown, a second rotating cylinder 61 is installed on the side of the second rod portion 42 away from the first rod portion 41. A bearing seat 6 is installed on the outer wall of the second rotating cylinder 61 through a bearing. The second rotating cylinder 61 rotates synchronously with the second rod portion 42. As Figure 7 shown, the cross-section of the second rod portion 42 is semi-circular, and the second rotating cylinder 61 is provided with a corresponding semi-circular groove. As Figure 2 shown, the second rod portion 42 includes a second wall surface 422, and the second wall surface 422 is arc-shaped. The second rod portion 42 includes a first wall surface 421, and the first wall surface 421 is a plane. The first wall surface 421 and the second wall surface 422 are the outer wall surfaces of the second rod portion 42.

[0037] As Figure 2 shown, on both sides of the second part 42 of the rod, there are first grooves 423. The length direction of the first grooves 423 is arranged along the length direction of the second part 42 of the rod. Insertion rods 43 are inserted into the first grooves 423. The insertion rods 43 are of an oval rod structure, and the width of the first grooves 423 is the same as that of the insertion rods 43. Combining Figure 3 and Figure 4 , at both ends of the second part 42 of the rod in the length direction, there are second grooves 424. The first grooves 423 are located between the two second grooves 424. The width of the first grooves 423 is smaller than that of the second grooves 424, and the insertion rods 43 are inserted into the second grooves 424. By providing the second grooves 424, it is convenient to take out the insertion rods 43 from the second grooves 424.

[0038] As Figure 2 shown, the second part 42 of the rod can be inserted into the groove 211. As Figure 8 shown, when the plate body 2 moves downward, the upper end of the second part 42 of the rod can abut against the film edge 71 and push up 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. During the convex process of the convex film 711, part of the film edge 71 is separated from the convex part 21.

[0039] As Figure 9 shown, as the second part 42 of the rod pushes up the film edge 71 upward, the second part 42 of the rod gradually moves upward away from the groove 211. When the position of the insertion rod 43 is higher than the convex part 21, the insertion rod 43 is pulled out radially outward along the second part 42 of the rod. The insertion rod 43 moves radially outward along the second part 42 of the rod to extend into the space between the wall surface of the convex part 21 and the film edge 71, so as to separate the wall surface of the convex part 21 from the film edge 71. When the insertion rod 43 is pulled out of the groove 211, the first wall surface 421 is arranged upward. By the insertion rod 43 extending 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 and the film edge 71 are separated, which is convenient for tearing the film body 7, and the film body 7 is not easily broken.

[0040] As Figure 1 shown, the rework device for the reverse wrapped edge film further includes a lifting plate 3. The lifting plate 3 passes through the moving seat 14. The upper end of the lifting plate 3 is driven by a connecting cylinder to realize up and down movement. As Figure 1 and Figure 2 shown, a fixed sleeve 31 is installed at the bottom of the lifting plate 3. A sliding rod 32 is slidably connected to the fixed sleeve 31. The sliding rod 32 can move up and down along the fixed sleeve 31. A pressing rod 34 is installed at the bottom of the sliding rod 32. A spring 33 is sleeved on the sliding rod 32. 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 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 42 of the rod are respectively located on both sides of the upper and lower lines of the film edge 71, and the pressure rod 34 and the second part 42 of the rod respectively abut against the upper and lower sides of the film edge 71. When the second part 42 of the rod rotates slowly, the second wall surface 422 rotates slowly. The second wall surface 422 stretches the film edge 71 through friction, so that the film edge 71 is slowly stretched horizontally, and the film edge 71 has a tendency to become thinner. The film edge 71 is stretched horizontally, and at the same time, there is a relative horizontal movement tendency between the film edge 71 and the convex part 21, so that the adhesive between the film edge 71 and the convex part 21 becomes loose, which is convenient for subsequent separation. And it can reduce the phenomenon that it is easy to tear due to too large vertical stretching amplitude in a short time during the process of the film edge 71 bulging upward to form the convex film 711. The rubber cushion layer can be installed on the second wall surface 422 as needed to increase the friction coefficient.

[0042] The rework method of the reverse edge wrapping film rework device includes the following steps:

[0043] ① Loading: The bottom of the plate body 2 is inserted into the substrate 13, and the pressing plate 142 moves downward to abut against the plate body 2 so as to fix the plate body 2.

[0044] ② As Figure 3 shown, install the rod body 4: The first part 41 of the rod is inserted into the first rotating cylinder 51, the second part 42 of the rod passes through the groove 211 and is inserted into the second rotating cylinder 61, and the second wall surface 422 faces upward.

[0045] ③ The substrate 13 moves downward to drive the plate body 2 to move downward until the second wall surface 422 and the pressure rod 34 press the film edge 71 against each other. The rod body 4 rotates slowly to make the second part 42 of the rod rotate slowly, so that the second wall surface 422 rotates and stretches the film edge 71 through friction, so that the film edge 71 is slowly stretched horizontally.

[0046] ④ As Figure 8 shown, when the second part 42 of the rod rotates to the state where the second wall surface 422 faces upward, the plate body 2 moves downward, and the second wall surface 422 pushes the film edge 71 upward to form the convex film 711.

[0047] ⑤ As Figure 9 shown, when the second part 42 of the rod rotates to the state where the first wall surface 421 faces upward, the plate body 2 moves downward, and the insertion rod 43 extends out of the upper end of the groove 211. Combining Figure 4 , pull out the insertion rod 43 from the groove 424. The pulling direction of the insertion rod 43 is along the left-right direction (a radial direction in the left-right direction of the second part 42 of the rod, and along the radially outward direction). When the insertion rod 43 is pulled out, the film edge 71 is separated from the convex part 21.

[0048] ⑥ Remove the entire film body 7 and then re-cover the film.

[0049] The film edge 71 is supported upward by the rod bipartite 42 to form a convex film 711. The rod bipartite 42 forms a supporting force on the film edge 71 in the entire width direction. When the raised part 21 is debonded and separated from the film edge 71, the force application points are increased, the phenomenon of partial disconnection of the film edge 71 during separation is reduced, and the operation is facilitated.

[0050] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
