[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the illustrative embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention. Example

[0037] See also Figure 1 This embodiment provides an automatic attaching device for lens cover film material of electronic products, including: Machine 1; A tray loading and unloading assembly 2, which is arranged on the machine platform 1 and is used to load and unload a loading tray on which a lens cover of an electronic product is placed; A film supply module 8, which is disposed on the machine 1 and is used to provide film materials; A film sticking assembly 5, which is arranged on the machine 1 and is used to stick the peeled film material to the lens cover of the electronic product; An exchange loading assembly 7, which is arranged on the machine 1 and is used to alternately carry the lens cover of the electronic product to the film application position; The multi-axis loading robot assembly 4 is arranged on the machine platform 1 and is used to transfer the lens cover of the electronic product between the tray loading and unloading assembly 2 and the exchange loading assembly 7.

[0039] See also Figure 3The exchange loading component 7 includes an exchange frame 70 arranged on the machine 1, an upper slide assembly 76 and a lower slide assembly 77 extending along the length direction of the exchange frame 70, a flip film frame 71 arranged at one end of the exchange frame 70, a flip beam 72 connected to the flip film frame 71 for sliding up and down, a film flip table 74 rotatably connected to the flip beam 72, an adsorption magnet 75 and a film material tray positioning block 764 arranged on the front of the film flip table 74, a flip motor 78 arranged on the flip beam 72 for driving the film flip table 74 to rotate around a horizontal rotation axis, and a flip lifting linear module 73 arranged on the machine 1 for driving the flip beam 72 to lift and lower. Film lifting components 79 are provided at the bottom of both ends of the exchange frame 70. The film lifting components 79 are used to lift the film material tray on the lower slide assembly 77 to the same height as the film material tray on the upper slide assembly 76.

[0040] The upper slide assembly 76 and the lower slide assembly 77 arranged in parallel can alternately load and unload materials, thereby improving the efficiency of loading and unloading materials and avoiding interference between the film pasting and the loading multi-axis robot assembly 4.

[0041] See also Figure 4 The film lifting assembly 79 includes a film lifting cylinder 791 disposed on the exchange frame 70 and a film lifting head 790 disposed on the film lifting cylinder 791.

The film transfer top column 547 is dynamically connected, and a plug 5470 is provided on the top of the film transfer top column 547. The plug 5470 is located in the film transfer vacuum chamber 546. The outer diameter of the bottom of the plug 5470 is larger than the aperture of the top opening of the film transfer vacuum suction nozzle 545. When the plug 5470 is in the lower limit position under the action of gravity, the bottom of the plug 5470 fits the bottom of the film transfer vacuum chamber 546 and blocks the top opening of the film transfer vacuum suction nozzle 545. The bottom of the film transfer top column 547 is lower than the bottom of the film transfer vacuum suction nozzle 545, and the bottom of the film transfer vacuum suction nozzle 545 is lower than the bottom of the film transfer vacuum seat 544. The film transfer top column 547 is used to lift the plug 5470 when sucking the film, so that the film transfer vacuum suction nozzle 545 can work normally. When the film transfer vacuum suction nozzle 545 has no film material, the plug 5470 blocks the film transfer vacuum suction nozzle 545, effectively preventing the vacuum from breaking and ensuring the stability of the remaining film material sucked. In order to ensure the sealing performance, a film transfer sealing ring 5471 may be provided at the top opening of the film transfer vacuum suction nozzle 545. A film transfer guiding camera 53 is provided on the film transfer moving module 50 to improve the accuracy of film transfer.

The stop point of the film transfer top column 547 against the film material is located at the center of the film material to prevent the film material from being too concave and causing defects in the film application. In order to prevent the lens cover of the electronic product from being damaged due to excessive pressure during film application, a film application elastic member 541 is connected between the film transfer seat 542 and the film transfer connecting seat 540, and the film application elastic member 541 applies a downward elastic force to the film transfer seat 542. A pressure sensor 548 is connected between the film transfer connecting seat 540 and the film transfer seat 542 to control the film application pressure.

The film bin 82 is surrounded by a plurality of vertical film bin blocks 820 arranged along the edge of the film, which has a simple structure and reduces the friction between the film and the film bin 82. The film carrier 84 is a vacuum suction cup table, which facilitates the film attachment component 5 to absorb the bottom film when taking the film, so as to separate the bottom film from the middle film. The film bins 82 at both ends of the film rotating beam 81 are used to realize film supply and film loading at the same time, thereby improving work efficiency.

The intermediate film stripping pneumatic jaw 861 is located directly above the top opening of the intermediate film disposal bin 87. The rotating intermediate film stripping pneumatic jaw 861 facilitates the smooth separation of the intermediate film from the required film material and facilitates the placement of the intermediate film into the intermediate film bin. The intermediate film stripping motor 862 is driven and connected to the intermediate film stripping pneumatic jaw 861 through a synchronous belt assembly 863. The intermediate film stripping pneumatic jaw 861 rotates smoothly to prevent the intermediate film from being separated from the film transfer head assembly 54 due to a large and violent pulling on the bottom film.
