[0056] Wherein, the placement module 2 includes:

[0057] A placement plate 21 is arranged on the transmission module 3;

[0058] A plurality of sets of sleeves 22 are evenly arranged on the placement plate 21, and are used for sleeves of the rings thereon to achieve placement of the rings;

[0059] A plurality of positioning components 23 are arranged on the placement plate 21 at the position of the sleeve column 22 and are used for positioning and placing the ring to cooperate with the film sticking module 4 to achieve film sticking on the ring.

[0060] In addition, the positioning component 23 includes:

[0061] A fixing plate 231 is fixedly disposed on one side of the placing plate 21;

[0063] After the ring is placed on the placement plate 21 through the sleeve 22, the ring is rotated to make the notch of the ring abut against the positioning plate 233. The abutment of the elastic telescopic rod 232 can prevent the ring from rotating during the movement and position the ring at the same time. In this way, when the film is pasted later, the position of the film and the ring can be matched, thereby achieving a better fitting effect.

[0064] At the same time, the transmission module 3 includes:

[0065] A loading conveyor belt 31 is provided on the machine body 1 and is used for loading and conveying the placement plate 21;

[0066] The unloading conveyor belt 32 is arranged on the machine body 1 and is used to unload the ring on the plate 21 after film application;

[0067] The transfer conveyor belt 33 is arranged on the machine body 1 and is located between the loading conveyor belt 31 and the unloading conveyor belt 32.

[0074] Wherein, the power part comprises:

[0075] A first threaded rod 413 is threadedly connected to a supporting plate 412, and a rotating motor 414 is provided at the lower end of the first threaded rod 413 for driving the first threaded rod 413 to rotate, so that the supporting plate 412 moves up and down. After the film laminating unit 42 takes away a piece of film, the power component drives the supporting plate 412 to move up a certain distance, so that the uppermost film is located at the top of the upper bin 411.

[0076] Meanwhile, the film sticking unit 42 includes:

[0077] The film sticking frame 421 is mounted on the machine body 1, and the machine body 1 is provided with a vacuum suction cup 422 for sucking the film at the upper end of the upper bin 411;

[0078] The moving component is arranged on the film sticking frame 421, and is used to drive the vacuum suction cup 422 to move to realize the film sticking action after suction.

[0079] Wherein, the mobile component comprises:

[0080] The longitudinal moving member 423 is disposed on the machine body 1 and is used to drive the vacuum suction cup 422 to move longitudinally;

[0081] The transverse moving member 424 is disposed on the longitudinal moving member 423 and is used to drive the vacuum suction cup 422 to move transversely;

[0082] Wherein, the longitudinal moving member 423 comprises:

[0083] A telescopic cylinder is fixed on the machine body 1, and a film sticking frame 421 is provided at the telescopic end of the telescopic cylinder;

[0084] In addition, the lateral moving member 424 includes:

[0085] A slide rail 4241 is fixedly arranged on the film sticking frame 421, a slide plate 4242 is slidably arranged on the slide rail 4241, a thread groove 4243 is arranged on the slide plate 4242, a second threaded rod 4244 is internally threadedly connected to the thread groove 4243, a moving motor 4245 is arranged at one end of the second threaded rod 4244 close to the film sticking frame 421, and the moving motor 4245 is fixedly arranged on the film sticking frame 421;

[0086] The elastic pressing member 425 is disposed between the transverse moving member 424 and the vacuum suction cup 422 and is used to realize elastic pressing of the film so that the film fits on the side of the ring.

[0087] In addition, the elastic pressing member 425 includes:

[0088] The slide cylinder 4251 is fixedly arranged at the lower end of the slide plate 4242. A slide column 4252 is provided in the slide cylinder 4251 for limited sliding movement. A vacuum suction cup 422 is provided at one end of the slide column 4252 away from the slide cylinder 4251. The vacuum suction cup 422 is arranged in a ring shape.

[0089] The pressing sheet 4253 is fixedly disposed on the outer ring of the slide cylinder 4251 and is used to press the outer ring of the membrane;

[0090] A pressing spring 4254 is disposed in the slide cylinder 4251, one end of which abuts against the slide column 4252, and the other end of which abuts against the slide plate 4242;

[0091] After the transverse moving member 424 sucks the film from the upper bin 411 through the vacuum suction cup 422 and moves to the circular ring on the transfer conveyor belt 33, the longitudinal moving member 423 drives the vacuum suction cup 422 to move downward. During the downward movement, the inner ring of the film will first fit on the upper surface of the circular ring. Then, when it continues to move downward, due to the abutment and limiting effect of the sliding column 4252 and the sleeve column 22, the sliding column 4252 will stop moving downward, and the slide cylinder 4251 will continue to move downward. At this time, the sliding column 4252 will be retracted toward the slide cylinder 4251. The pressing spring 4254 is compressed, so that the pressing sheet 4253, which has an outer diameter slightly larger than the circular ring, presses the outer ring of the film. In the process of moving down, the outer ring of the film is attached to the side ring of the circular ring, thereby completing the film sticking action on the upper surface and the side ring of the circular ring. After the film sticking action is completed, the vacuum suction cup 422 ends the adsorption and resets, and continues to adsorb the next film under the action of the moving component. The transfer conveyor 33 transports the next circular ring forward by one end to move it to the horizontal position for film sticking operation.

[0092] Finally, an imaging device 426 is provided on the body 1 between the loading bin 411 and the transfer conveyor belt 33. The imaging device 426 can be provided with a camera to capture the position of the vacuum suction cup 422 after taking the film out of the loading bin 411. A rotating motor 427 is provided on the slide plate 4242 located in the slide cylinder 4251. A telescopic rod 428 is provided at the rotating end of the rotating motor 427. The telescopic rod 428 is connected to the slide column 4252. When the film position photo taken at the position of the imaging device 426 is inconsistent with the direction of the circular ring position on the placement plate 21, the rotating motor 427 is used to drive the cylinder to rotate, so as to adjust the position of the film to be consistent with the circular ring, and then continue to move the film to the circular ring position through the lateral moving member 424.
