[0002] With the demands of image recognition and photography, cameras have become essential accessories for many handheld terminals, especially mobile phones.

Therefore, in order to prevent contamination and scratching inside the lens cover, a protective film is usually attached to the inner side of the lens module. Since the lens cover on the handheld terminal is usually small in size, the traditional manual film pasting method has low efficiency and unstable fitting accuracy. Summary of the Invention

[0051] The loading multi-axis manipulator assembly 4 is arranged on the machine table 1 and is used for transferring the lens cover of the electronic product between the tray loading and unloading assembly 2 and the exchange loading assembly 7.

[0052] The above realizes the rapid supply of the lens cover of the electronic product to the film attaching position through the exchange loading assembly 7, improving the film attaching efficiency; realizes automatic film supply through the film supply assembly and the film tearing assembly, improving the supply efficiency of the film material. The film attaching assembly 5 and the exchange loading assembly 7 can stably attach multiple film materials at one time, improving the efficiency and the stability of the film attaching accuracy.

[0053] Please refer to Figure 3, the exchange and loading component 7 includes a switch frame 70 disposed on the machine table 1, an upper slide table component 76 and a lower slide table component 77 extending along the length direction of the switch frame 70, a flipping and film - sticking frame 71 disposed at one end of the switch frame 70, a flipping cross beam 72 slidably connected to the flipping and film - sticking frame 71 in the up - and - down direction, a film - sticking flipping table 74 rotatably connected to the flipping cross beam 72, an adsorption magnet 75 and a film - sticking material tray positioning block disposed on the front surface of the film - sticking flipping table 74, a flipping motor 78 disposed on the flipping cross beam 72 for driving the film - sticking flipping table 74 to rotate around a horizontal rotation axis, a flipping lifting linear module 73 disposed on the machine table 1 for driving the flipping cross beam 72 to lift and lower. At the bottom of both ends of the switch frame 70, there are film - sticking lifting components 79, and the film - sticking lifting components 79 are used to lift the film - sticking material tray on the lower slide table component 77 to the same height as the film - sticking material tray on the upper slide table component 76.

The plug 5470 is located inside the film transferring vacuum cavity 546. The outer diameter of the bottom of the plug 5470 is larger than the aperture of the top opening of the film transferring vacuum suction nozzle 545. When the plug 5470 is at the lower limit under the action of gravity, the bottom of the plug 5470 fits against the bottom of the film transferring vacuum cavity 546 and blocks the top opening of the film transferring vacuum suction nozzle 545. The bottom of the film transferring top column 547 is lower than the bottom of the film transferring vacuum suction nozzle 545, and the bottom of the film transferring vacuum suction nozzle 545 is lower than the bottom of the film transferring vacuum seat 544. When sucking the film, the film transferring top column 547 jacks up the plug 5470, and the film transferring vacuum suction nozzle 545 can work normally. When there is no film material in the film transferring vacuum suction nozzle 545, the plug 5470 blocks the film transferring vacuum suction nozzle 545, effectively preventing vacuum breakage and ensuring the stability of the remaining film materials sucked. In order to ensure the sealing performance, a film transferring sealing ring 5471 can be provided at the top opening of the film transferring vacuum suction nozzle 545.

The point where the film transferring top column 547 abuts against the film material is located at the center of the film material, preventing the film material from being too concave and causing defects in film pasting. In order to prevent damage to the lens cover of the electronic product due to excessive pressure during film pasting, a film pasting elastic member 541 is connected between the film transferring seat 542 and the film transferring connection seat 540.
