[0030] The following will be described in detail in combination with the accompanying Figures 1-2 The present application is further described in detail.
[0031] The embodiment of the present application discloses a Mylar auxiliary pasting structure, which is applied to an automatic Mylar pasting machine. Referring to Figure 1 , the Mylar auxiliary pasting structure comprises an upper die 1 and a lower die 2, the upper die 1 is used for sucking a Mylar film 3, the Mylar film 3 is uniformly coated with adhesive glue (not shown in the drawing) on a contact surface of a metal sheet to be pasted 4, and the upper die 1 can paste the Mylar film 3 on the metal sheet to be pasted 4; the lower die 2 is used for containing the metal sheet to be pasted 4, and the upper die 1 and the lower die 2 cooperate to complete the pasting of the Mylar film 3.
[0032] Referring to Figure 1 , the Mylar auxiliary pasting structure further comprises an auxiliary pressing plate 5, the auxiliary pressing plate 5 is made of butadiene rubber and has strong elasticity, the auxiliary pressing plate 5 is fixedly connected to one side of the upper die 1 close to the lower die 2, the auxiliary pressing plate 5 is provided with a vertical groove 51 penetrating along the thickness direction of the auxiliary pressing plate 5, the vertical groove 51 is in a cylindrical shape, a plurality of vertical grooves 51 are arranged, the positions of the plurality of vertical grooves 51 are corresponding to the positions of protruding parts 41 on the metal sheet to be pasted 4, and in the embodiment, the protruding parts 41 on the metal sheet to be pasted 4 are in the shape of round bumps, and it should be noted that the hole diameter of the vertical groove 51 can ensure that the inner circumferential wall of the vertical groove 51 does not rub against the outer circumferential wall of the protruding parts 41 on the metal sheet to be pasted 4.
[0033] When the melamine film 3 is attached, the melamine film 3 is sucked to the auxiliary pressing plate 5 through the upper die 1. Since the auxiliary pressing plate 5 has flexibility, on the one hand, the auxiliary pressing plate 5 can protect the metal piece 4 to be attached with the melamine film, especially the protruding part 41 of the metal piece 4 to be attached with the melamine film, thereby reducing the possibility that the protruding part 41 of the metal piece 4 to be attached with the melamine film is extruded and deformed when the melamine film 3 is attached; on the other hand, the hard contact is changed to soft contact, and the melamine film 3 at the position of the protruding part 41 of the metal piece 4 to be attached with the melamine film is compacted through the extrusion deformation of the auxiliary pressing plate 5 and the force applied by the end face of the vertical groove 51 to the edge of the protruding part 41, thereby reducing the possibility that the melamine film 3 at the position of the protruding part 41 of the metal piece 4 to be attached with the melamine film is not firmly bonded and is warped, and improving the attachment effect of the melamine film 3.
[0034] With reference to Figure 1 and Figure 2 The side of the auxiliary pressing plate 5 close to the lower die 2 is attached with sponge blocks 6. The sponge blocks 6 are in a cylindrical shape, and the sponge blocks 6 are coaxially arranged with the vertical grooves 51. The number of the sponge blocks 6 is the same as the number of the vertical grooves 51 and corresponds to the vertical grooves 51 one by one. A through hole 61 is formed in the middle position of each sponge block 6, and the inner circumferential wall of the through hole 61 is flush with the inner circumferential wall of the vertical groove 51. The side of the auxiliary pressing plate 5 close to the lower die 2 is surrounded and attached with sponge strips 7. The positions of the sponge strips 7 correspond to the positions of the edges of the metal piece 4 to be attached with the melamine film, and the end face of the end of the sponge strip 7 away from the auxiliary pressing plate 5 is flush with the end face of the end of the sponge block 6 away from the auxiliary pressing plate 5.
[0035] When the melamine film 3 is attached, the auxiliary pressing plate 5 is downwardly extruded and deformed, and the sponge block 6 at the edge position of the protruding part 41 of the metal piece 4 to be attached with the melamine film can be further extruded and deformed, thereby further applying force to the edge of the protruding part 41 of the metal piece 4 to be attached with the melamine film, so that the melamine film 3 at the edge of the protruding part 41 of the metal piece 4 to be attached with the melamine film is more firmly bonded. When the auxiliary pressing plate 5 is downwardly extruded and deformed, the sponge strip 7 can also be extruded and deformed at the same time, thereby applying force to the edge of the metal piece 4 to be attached with the melamine film, so that the melamine film 3 at the edge of the metal piece 4 to be attached with the melamine film is more firmly bonded, and the attachment effect of the melamine film 3 is further improved.
[0036] The implementation principle of the melamine auxiliary attachment structure is as follows: when the melamine film 3 is attached, the melamine film 3 is sucked to the auxiliary pressing plate 5 through the upper die 1. Since the auxiliary pressing plate 5 has flexibility, on the one hand, the auxiliary pressing plate 5 can protect the metal piece 4 to be attached with the melamine film, especially the protruding part 41 of the metal piece 4 to be attached with the melamine film, thereby reducing the possibility that the protruding part 41 of the metal piece 4 to be attached with the melamine film is extruded and deformed when the melamine film 3 is attached; on the other hand, the hard contact is changed to soft contact, and the melamine film 3 at the position of the protruding part 41 of the metal piece 4 to be attached with the melamine film is compacted through the extrusion deformation of the auxiliary pressing plate 5, thereby reducing the possibility that the melamine film 3 at the position of the protruding part 41 of the metal piece 4 to be attached with the melamine film is not firmly bonded and is warped, and improving the attachment effect of the melamine film 3.
[0037] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
