Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to a device for laminating films on five surfaces of a workpiece. Background Art

[0002] Existing chargers generally use a frame-shaped shell with a closed structure at one end and a base with a packaging cover on the open end of the frame-shaped shell. Various electronic components on the charger are integrated on the base. After the frame-shaped shell and the base with various electronic components integrated are fixed by fixing structures such as buckles, the finished product assembly of the charger is completed; during the production and packaging process of the charger shell, in order to make the surface of the frame-shaped shell smooth and not wear-resistant, after the frame-shaped shell is manufactured, a protective film is affixed to the five surfaces of the frame-shaped shell for protection; some frame-shaped shells also have an arc transition between each two adjacent side surfaces to improve the overall appearance of the charger. When the frame-shaped shell with an arc structure is protected by a film, two sections are extended from the two opposite side films to wrap and fit along the arc, so that the frame-shaped shell can be protected by a film on the five surfaces with arc transitions with only one protective film, such as Figure 1 As shown, it is the shape after the frame-shaped housing and the protective film corresponding to the frame-shaped housing are bonded together;

[0003] Since the five-sided film pasting operation is relatively complicated and difficult to achieve fully automated pasting, the existing film pasting operation of this type often needs to be performed manually.

This operation not only incurs a large labor cost, but also there will be large errors in the manual film pasting method, and it will also incur certain labor training costs.

[0027] See also Figure 1-5In the embodiment of the utility model, an automated device is used to perform film laminating operation on five surfaces of a workpiece 2 (charger shell). The protective film 1 is an integrated structure, having a top surface for attaching to the top of the workpiece 2 and four side surfaces for attaching to the side of the workpiece 2, and two of the opposite side surfaces have extensions for laminating the four arc surface transition positions on the side of the workpiece 2; specifically, a workpiece five-surface film laminating device is provided, including an operating table 10, on which a film unwinding mechanism 11, a film winding mechanism 12, a forward film tearing mechanism 20, a film sucking and pressing mechanism 30, a side film pressing mechanism 40 and a workpiece fixing station 13 are provided, the film unwinding mechanism 11 is used to install a coil 14, the coil 14 bypasses the forward film tearing mechanism 20 and then docks with the film winding mechanism 12, the film winding mechanism 12 is used to recycle the coil 14, and on the coil 14 A protective film 1 acting on the workpiece 2 is attached at equal intervals, and the forward film tearing mechanism 20 is used to tear off the protective film 1 on the coil 14, and the forward film tearing mechanism 20 moves the torn protective film 1 to a position between the film suction and film pressing mechanism 30 and the workpiece fixing station 13 by moving forward. The film suction and film pressing mechanism 30 has a lifting power mechanism 31 installed on the operating table 10, a side film suction mechanism 32 connected to the power end of the lifting power mechanism 31, a top film pressing mechanism 33 connected to the power end of the lifting power mechanism 31, and a side film pressing roller wheel 34 connected to the power end of the lifting power mechanism 31; the side film pressing mechanism 40 has a side driving force unit 41 installed on the operating table 10 and a side film side pressing roller wheel 42 connected to the side driving force unit 41 for turning the side of the protective film 1 to the other side of the workpiece 2 and rolling it for bonding.

[0028] During the operation, the employee takes and places the workpiece 2 in front of the operating table 10. When the workpiece 2 is positioned and placed on the workpiece fixing station 13, the forward-moving film tearing mechanism 20 operates to push the coil 14 to the bottom of the film suction and pressing mechanism 30. The film suction and pressing mechanism 30 moves down and sucks the side of the protective film 1 through the side film suction mechanism 32. After sucking, the forward-moving film tearing mechanism 20 retreats. During the retreat, the film winding mechanism 12 operates to rewind the coil 14 so that the protective film on the coil 14 During the process of the protective film 1 being sucked by the side film suction mechanism 32, the coil 14 can tear the protective film 1 along the retreat of the forward tearing film mechanism 20 and the winding of the film winding mechanism 12, so that the protective film 1 can be torn and adsorbed on the side film suction mechanism 32; then the lifting power mechanism 31 operates to move the protective film 1 down to the workpiece 2 docked on the workpiece fixing station 13, and at the same time the lifting power mechanism 31 continues to operate, through the top film pressing mechanism 33 and the side film pressing roller wheel 34 The protective film 1 is initially attached to the top of the workpiece 2 by the top film pressing mechanism 33, and then the protective film 1 is rolled from top to bottom and attached to the side of the workpiece 2 by the side film pressing roller wheel 34. During this process, the side film suction mechanism 32 can be operated synchronously with the top film pressing mechanism 33 and the side film pressing roller wheel 34, or a limiting mechanism, an elastic mechanism and other mechanisms can be set to enable the side film suction mechanism 32 to stop after docking with the workpiece 2 while the top film pressing mechanism 33 and the side film pressing roller wheel 34 continue to move downward; after the protective film 1 is initially attached, since the protective film 1 still has two opposite sides with extended parts that have not been bonded, this operation is achieved by the side film pressing mechanism 40 set up. Specifically, the side film side pressing roller wheel 42 is driven by running the side driving force unit 41 to attach the extended part to the workpiece 2 in another direction perpendicular to the movement of the side film pressing roller wheel 34.

The pressing cylinder 312 on the plug end and the side film suction mechanism 32 are connected to the piston end of the lifting cylinder 311, and the top film pressing mechanism 33 and the side film pressing roller wheel 34 are both connected to the piston end of the pressing cylinder 312; through this arrangement, the action of the side film suction mechanism 32 moving downward to suck material and continuing to move downward to attach the protective film 1 to the workpiece 2 is provided by the lifting cylinder 311, and the continued downward movement of the top film pressing mechanism 33 and the side film pressing roller wheel 34 is provided by the pressing cylinder 312.

[0031] See also Figure 3 In this embodiment, the side film suction mechanism 32 is a frame structure, which is used to suck the four sides of the protective film 1 so that the protective film 1 can be more firmly adsorbed.

This arrangement makes it convenient for the operator to take and place the workpiece 2. That is, each time the workpiece 2 is taken and placed, the forward push cylinder 15 drives the front push plate 16 to push forward, so that the workpiece fixing station 13 is separated from the lower part of the film suction and film pressing mechanism 30. After the operator takes and places the workpiece 2, the forward push cylinder 15 continues to drive the workpiece fixing station 13 through the front push plate 16 to enter the lower part of the film suction and film pressing mechanism 30, so as to avoid the operator being disturbed by the film suction and film pressing mechanism 30 when taking and placing the workpiece 2.
