The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0023] Next, the embodiments of the present utility model will be described according to its overall structure.

[0024] An automatic random film - sticking mechanism for metal accessories of intelligent terminal devices, as Figures 1-5As shown in the figure, it includes a base 1. A fixed plate 2 is fixed on the side wall of the base 1. An installation plate 3 is fixed above the fixed plate 2. A cylinder 4 is fixed at the upper end of the installation plate 3. A film pasting assembly is arranged below the installation plate 3. A conveying assembly, a rolling assembly and a pushing assembly are arranged inside the base 1. The film pasting assembly includes a moving plate 510. An installation block 520 is fixed below the moving plate 510. A pressing block 530 is arranged below the installation block 520. Cutting knives 540 are arranged around the installation block 520. A film releasing wheel 550 is arranged on one side of the cutting knives 540. A winding wheel 560 is arranged on the other side of the cutting knives 540. A first one-way gear 580 is arranged on one side of the winding wheel 560. A first rack 570 is arranged on one side of the first one-way gear 580. The pressing block 530 is slidably installed inside the installation block 520, and a spring is arranged between the inner wall of the installation block 520 and the pressing block 530. The cutting knives 540 are fixedly installed at the lower end of the moving plate 510, and the upper end of the moving plate 510 is fixedly connected to the output end of the cylinder 4. The winding wheel 560 and the first one-way gear 580 are fixedly sleeved on the outer wall of the same rotating rod. The first one-way gear 580 is engaged with the first rack 570. The first rack 570 is fixedly installed on the side wall of the fixed plate 2. The film releasing wheel 550 is rotatably installed on the side wall of the moving plate 510.

[0025] The output end of the cylinder 4 moves downward, driving the moving plate 510 to move downward, and at the same time driving the installation block 520 and the pressing block 530 downward. The film is attached to the part through the pressing block 530. The moving plate 510 continues to move downward, and the cutting knives 540 cut the film. After completion, the cylinder 4 resets, driving the first one-way gear 580 to rotate through the first rack 570. The first one-way gear 580 drives the winding wheel 560 to wind through the rotating rod, so that the film releasing wheel 550 releases the film, and thus a new film is placed below the pressing block 530. When the moving plate 510 moves downward, the first one-way gear 580 will not drive the winding wheel 560 to rotate.

[0026] Please refer specifically to Figures 1-3 , the pushing assembly includes a second rack 610. A second one-way gear 630 is arranged on one side of the second rack 610. A threaded rod 640 is arranged inside the second one-way gear 630. A moving column 650 is arranged on the outer wall of the threaded rod 640. A push plate 660 is fixedly installed on one side of the moving column 650. A connecting plate 670 is arranged on one side of the push plate 660. The top end of the second rack 610 is fixedly connected to the moving plate 510. The second rack 610 is engaged with the second one-way gear 630. The second one-way gear 630 is fixedly sleeved on the outer wall of the threaded rod 640. One end of the threaded rod 640 is rotatably installed inside the base 1 through a torsion spring wheel 620. The moving column 650 is movably sleeved on the outer wall of the threaded rod 640 through a thread.

[0027] When the moving plate 510 moves downward, it drives the second one-way gear 630 to rotate through the second rack 610. The rotation of the second one-way gear 630 drives the threaded rod 640 to rotate, and then drives the moving column 650 to move to one side, driving the push plate 660 to move to one side. In cooperation with the connecting plate 670, it pushes and resets the displaced parts. When the second rack 610 moves to a certain position, it disengages from the second one-way gear 630, and the threaded rod 640 is reset through the torsion spring wheel 620, driving the moving column 650 and the push plate 660 to reset. When the second rack 610 moves upward, the second one-way gear 630 will not drive the threaded rod 640 to rotate.

[0028] Please refer specifically to Figures 1-3 , the conveying assembly includes a third rack 810. One side of the third rack 810 is meshed and connected with a third one-way gear 820. One side of the third one-way gear 820 is connected to a first transmission wheel 830 through a rotating rod. Both sides of the first transmission wheel 830 are connected to a second transmission wheel 840 through a transmission belt. The second transmission wheel 840 is fixedly sleeved on the outer wall of the rotating rod of the conveying wheel 850. A conveyor belt is sleeved on the outer wall of the conveying wheel 850. A support plate 9 is arranged below the conveyor belt, and the support plate 9 is fixedly installed on the inner wall of the base 1.

[0029] When the third rack 810 moves downward, it drives the third one-way gear 820 to rotate. The third one-way gear 820 will not drive the first transmission wheel 830 to rotate. On the contrary, when the third rack 810 moves upward, it drives the third one-way gear 820 to rotate, and then the third one-way gear 820 drives the first transmission wheel 830 to rotate. The first transmission wheel 830 and the second transmission wheel 840 are driven by a transmission belt, and then drive the conveying wheel 850 and the conveyor belt to convey the parts.

[0030] Please refer specifically to Figure 1 and Figure 5 , the rolling assembly includes a mounting column 710. The mounting column 710 is connected to a connecting frame 720 through a connecting rod below, and a spring is arranged between the connecting rod and the inner wall of the mounting column 710. A rolling wheel 730 is rotatably installed inside the connecting frame 720.

[0031] After the parts with the film pasted move below the rolling wheel 730, the film on the surface of the parts is rolled and fixed by the rolling wheel 730.

[0032] During use, the output end of the air cylinder 4 moves downward, driving the moving plate 510 to move downward. At the same time, it drives the mounting block 520 and the pressing block 530 downward. The film is attached to the part through the pressing block 530. The moving plate 510 continues to move downward, and the cutting knife 540 shears the film. After completion, the air cylinder 4 resets, driving the first one-way gear 580 to rotate through the first rack 570. The first one-way gear 580 drives the winding wheel 560 to wind through the rotating rod, so that the film feeding wheel 550 feeds the film, and thus a new film is placed under the pressing block 530. When the moving plate 510 moves downward, the first one-way gear 580 will not drive the winding wheel 560 to rotate. When the moving plate 510 moves downward, it drives the second one-way gear 630 to rotate through the second rack 610. The rotation of the second one-way gear 630 drives the threaded rod 640 to rotate, and then drives the moving column 650 to move to one side, driving the push plate 660 to move to one side. Cooperating with the connecting plate 670, it pushes and resets the displaced part. When the second rack 610 moves to a certain position, it disengages from the second one-way gear 630, and the threaded rod 640 resets through the torsion spring wheel 620, driving the moving column 650 and the push plate 660 to reset. When the second rack 610 moves upward, the second one-way gear 630 will not drive the threaded rod 640 to rotate. When the third rack 810 moves downward, it drives the third one-way gear 820 to rotate. The third one-way gear 820 will not drive the first transmission wheel 830 to rotate. On the contrary, when the third rack 810 moves upward, it drives the third one-way gear 820 to rotate, and then the third one-way gear 820 drives the first transmission wheel 830 to rotate. The first transmission wheel 830 and the second transmission wheel 840 are driven by a transmission belt, and then drive the conveying wheel 850 and the conveyor belt to convey the parts. The parts not involved in this device are the same as the prior art or can be implemented by using the prior art.
