This shape meets the needs of most families, but the surface of this type of plug is smooth, and insufficient friction will occur during plugging and unplugging, resulting in difficulty in plugging and unplugging. In addition, the edges of this type of plug are right-angled, which is easy to be scratched or bumped during plugging and unplugging. Therefore, the charger products designed now will be designed with some special-shaped arc surfaces or concave positions while meeting the use requirements, which can increase the plugging and unplugging process. Friction, and better appearance. In the production process of this type of new charger, in order to avoid scratches or bumps on the product due to vibration during delivery and transportation, the product will be filmed before packaging so that the surface of the product can remain clean when consumers buy it. At present, the film is mainly applied manually, which has high labor costs and low precision, and is prone to crooked pasting, with low film pasting efficiency. Alternatively, multiple groups of cylinders are used to drive the film pasting head to apply film on multiple sides. This method meets the film pasting requirements of the plane structure.

DETAILED DESCRIPTION

[0014] like Figures 1 to 8As shown, in this embodiment, the present invention includes a lifting component 1, an opening and closing component 2 and a film head component 3, the film head component 3 includes a film clamping claw module 4 and a closing and pressure-maintaining module 5, the film clamping claw module 4 includes a film clamping claw mounting plate 41 and a plurality of film clamping claws 42, the movable end of the lifting component 1 is connected to the film clamping claw mounting plate 41, the opening and closing component 2 is arranged on one side of the lifting component 1, the movable end of the opening and closing component 2 passes through the film clamping claw mounting plate 41 and cooperates with the plurality of film clamping claws 42, the closing and pressure-maintaining module 5 is arranged at the lower end of the film clamping claw mounting plate 41 and cooperates with the plurality of film clamping claws 42, the lifting component 1 and the opening and closing component 2 drive the plurality of film clamping claws 42 to cooperate with the corner profiled surface of the product 6 shell. It can be seen that the shell corner special-shaped curved film-sticking mechanism is mainly composed of a contoured film-sticking head integral lifting cylinder assembly, a contoured film-sticking head opening drive cylinder assembly, a contoured film-sticking head and a film-sticking head closing pressure-maintaining cylinder assembly. When the product to be coated moves to the bottom of the mechanism, the lifting assembly 1 and the opening and closing assembly 2 drive the film-sticking head assembly 3 to descend synchronously and synchronously press the four corner arc surfaces of the product 6. The structure is simple, and there is no need for multiple groups of cylinders to drive the film-sticking heads to press multiple corner special-shaped edges separately, so the efficiency is higher.

[0015] like Figure 1 and Figure 3 As shown, in this embodiment, the lifting assembly 1 includes a lifting mounting base 11, a lifting cylinder mounting plate 12 and a lifting cylinder 13. The lifting cylinder mounting plate 12 is arranged at the lower end of the lifting mounting base 11, and the lifting cylinder 13 is arranged on one side of the lifting cylinder mounting plate 12. The movable end of the lifting cylinder 13 is connected to one side of the film clamping claw 42. It can be seen that the lifting mounting base 11 can be connected to the fixed position of the machine platform, and the lifting cylinder 13 drives the opening and closing assembly 2 to realize the movement in the Z-axis direction to meet the demand for downward positioning.

[0016] like Figure 1 and Figure 4As shown, in this embodiment, the opening and closing assembly 2 includes an opening and closing cylinder mounting plate 21 and an opening and closing cylinder 22. The opening and closing cylinder mounting plate 21 is slidably matched with the lifting cylinder mounting plate 12 through a plurality of slide rail modules 23. The lower end of the opening and closing cylinder mounting plate 21 is connected to the film-sticking jaw mounting plate 41. The opening and closing cylinder 22 is arranged on one side of the opening and closing cylinder mounting plate 21. The opening and closing cylinder 22 passes through the film-sticking jaw mounting plate 41 and matches with a plurality of the film-sticking jaws 42. It can be seen that the opening and closing cylinder 22 follows the movement of the movable end of the lifting cylinder 13 to achieve the adjustment in the Z-axis direction. When the movable end of the opening and closing cylinder 22 is in the reset state, the four groups of the film-sticking jaws 42 open outward and separate from the product 6. When the movable end of the opening and closing cylinder 22 is extended, a plurality of the film-sticking jaws 42 are mutually attached, and the edge of the product can be pressed by the lifting cylinder 13.

[0017] like Figures 5 to 8 As shown, in the present embodiment, an opening and closing driving roller module 43 is provided in the middle of the lower end surface of the film clamping jaw mounting plate 41, and the upper ends of several of the film clamping jaws 42 are floatingly connected to the lower end surface of the film clamping jaw mounting plate 41 through buffer springs 44, and several movable ends of the opening and closing driving roller module 43 are respectively connected to the inner sides of several of the film clamping jaws 42, and an opening and closing driving shaft 45 is provided in the middle of the upper end of the film clamping jaw mounting plate 41, and the lower end of the opening and closing driving shaft 45 passes through the film clamping jaw mounting plate 41 and is connected to the driving end of the opening and closing driving roller module 43, and the upper end of the opening and closing driving shaft 45 is connected to the movable end of the cylinder of the opening and closing component 2. It can be seen that the opening and closing driving roller module 43 converts the extension and retraction movement of the cylinder into the closing and opening movement of the four contoured film heads by driving the roller to roll on the curved surface of the mounting part, so as to control the opening and closing of the four contoured film heads, and synchronously enable the several film clamps 42 to be opened or restored, and the buffer spring 44 provides the function of pressing buffer and resetting the several film clamps 42.

[0018] like Figures 5 to 8 As shown, in this embodiment, the closed pressure-maintaining module 5 includes a pressure-maintaining cylinder support plate 51 and a plurality of pressure-maintaining cylinders 52. The pressure-maintaining cylinder support plate 51 is connected to the film-applying jaw mounting plate 41 through a plurality of adapter plates 53. A clearance opening 54 is provided in the middle of the pressure-maintaining cylinder support plate 51. The clearance opening 54 cooperates with the film-applying jaw module 4. A plurality of the pressure-maintaining cylinders 52 are provided at the lower end of the pressure-maintaining cylinder support plate 51. The movable ends of the pressure-maintaining cylinders 52 respectively cooperate with the outer sides of the corresponding film-applying jaws 42. It can be seen that during the pressing process, the movable ends of the four groups of the pressure-maintaining cylinders 52 extend out to contact the outer sides of the four groups of the film-applying jaws 42, and drive the film-applying jaws 42 to press the product 6, which can achieve a pressure-maintaining effect and prevent the film from warping or falling off.

[0019] like Figures 2 to 4 As shown, in this embodiment, a plurality of pressing stoppers 7 are arranged on both sides of the lifting cylinder mounting plate 12, and a plurality of pressing stop blocks 8 are arranged on both sides of the opening and closing cylinder mounting plate 21, and the plurality of pressing stop blocks 8 cooperate with the plurality of pressing stoppers 7. It can be seen that the plurality of pressing stoppers 7 can prevent the plurality of film clamping jaws 42 from overpressing the product 6.

[0020] like Figure 6 and Figure 7 As shown, in this embodiment, the pressing end of the film-sticking clamping jaw 42 is provided with a curved profile groove 9, and the curved profile groove 9 matches the corner profile surface of the shell of the product 6. It can be seen that the curved profile groove 9 is adapted to the corner profile surface of the shell of the product 6, and the initial film-sticking positioning can be achieved during the sticking process to prevent the film from folding. In addition, according to products of different sizes and shapes, the film-sticking clamping jaw 42 can be replaced for quick adaptation, and the applicability is strong.

[0021] like Figure 6 and Figure 7 As shown, in this embodiment, a flexible adhesive layer is provided on the contact surface between the curved profile groove 9 and the corner profile surface of the shell of the product 6. It can be seen that the flexible adhesive layer plays a role of buffering and scratch prevention, ensuring the film-sticking yield of the product before leaving the factory.

[0022] The working principle of the present invention is as follows: the product 6 with preliminary film sticking moves to the bottom of the film sticking mechanism and stops, the movable end of the opening and closing cylinder 22 extends, and the four groups of film sticking jaws 42 are closed under the action of spring force; the lifting cylinder 13 drives the four groups of film sticking jaws 42 to descend, and the curved surface profiling groove 9 on the film sticking jaws 42 is in contact with the corner irregular surface of the shell of the product 6 to achieve preliminary pressing, and the movable ends of the four groups of pressure-maintaining cylinders 52 extend laterally to press the film sticking jaws 42, and after the pressure holding is completed, the four groups of pressure-maintaining cylinders 52 are reset, the movable end of the opening and closing cylinder 22 is reset, and the four groups of film sticking jaws 42 are opened, and the lifting cylinder 13 drives the four groups of film sticking jaws 42 to rise and separate from the product, and the product 6 with film sticking is replaced, and the above steps are repeated to achieve pressing and pressure holding of the four irregular arc surfaces on the edge of the product.

[0023] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
