[0110] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0111] See also Figure 1 The present application provides a film pasting device 100 for pasting a first film 300 and a second film 400 on a workpiece 200. In this embodiment, the workpiece 200 is a flat back cover, and a camera glass is provided on the workpiece 200. The first film 300 and the second film 400 are pasted on the camera glass of the workpiece 200 to protect the camera glass. The film pasting device 100 includes a base 10, a conveying mechanism 20, and a pick-and-place mechanism 30, a rotating mechanism 40, a cleaning mechanism 50, a wiping mechanism 60, and a film pasting mechanism 70, which are respectively arranged on the base 10 at intervals.

[0112] The conveying mechanism 20 is disposed on one side of the base 10 , one end of the pick-and-place mechanism 30 extends above the conveying mechanism 20 , and the pick-and-place mechanism 30 , the cleaning mechanism 50 , the wiping mechanism 60 and the film-applying mechanism 70 are respectively located around the rotating mechanism 40 . The conveying mechanism 20 conveys the workpiece 200 to the vicinity of the pick-up and placement mechanism 30. The pick-up and placement mechanism 30 removes the workpiece 200 and places the workpiece 200 on the rotating mechanism 40. The rotating mechanism 40 drives the workpiece 200 to rotate in sequence to the cleaning mechanism 50, the wiping mechanism 60, the film-laminating mechanism 70 and the pick-up and placement mechanism 30.

A plurality of suction holes 7232 for sucking the first film 300 are opened on the side of the second suction member 723 away from the second elastic member 721. The suction holes 7232 are connected to the storage cavity 7231. The first suction member 722 is arranged in the storage cavity 7231, and is used to suck the second film 400 on the side of the second suction member 723 away from the second elastic member 721.

[0130] In this embodiment, the film sticking driving member 71 includes a four-axis manipulator 711, a rotating cylinder 712 connected to the four-axis manipulator 711, and a film sticking cylinder 713 connected to the rotating cylinder 712. The film sticking cylinder 713 is connected to the elastic film sticking assembly 72 to drive the elastic film sticking assembly 72 to rise and fall. The second elastic member 721 is an elastic column with equal height. The first suction member 722 and the second suction member 723 are both connected to the external air source. In this way, by setting the rotating cylinder 712, the adjustment of the film sticking angle can be achieved at a low cost. By setting the film sticking cylinder 713, the second elastic member 721, the first suction member 722 and the second suction member 723 can be driven to achieve flexible film sticking.

[0131] The first suction piece 722 and the second suction piece 723 can realize the simultaneous attachment of two protective films of different specifications, which greatly improves the efficiency of film attachment. Since the material of the first film 300 is relatively thick, if the traditional film attachment method (straight up and straight down) is adopted, air holes will remain on the workpiece 200 after the attachment is completed. Therefore, in this case, 30° attachment (negative pressure disconnects and positive pressure opens) is adopted to make the first film 300 fit to the workpiece 200 to solve the air hole problem.
