Description

Technical Field

[0001] This utility model relates to the field of sorting machine technology, specifically to an intelligent image chain automatic sorting machine. Background Technology

[0002] In the chain manufacturing process, chain pieces, as the core component of the chain, directly affect the production progress of the subsequent chain assembly machine due to the accuracy and efficiency of their placement and specification selection. For the production of 80-size chains, chain pieces must be precisely placed with the "logo face to the same direction" requirement before being conveyed to the 80-size chain assembly machine for assembly. Each worker can place 25 pieces per minute, requiring four workers to achieve a rate of 60 pieces per minute to meet the demands of the 80-size chain assembly machine. Manual placement is inefficient and costly, and relying on manual identification can lead to fatigue and incorrect placement. Furthermore, chain pieces with different logos, inner hole sizes, and appearances are mixed, making manual sorting difficult. Therefore, with technological advancements, chain piece sorting machines were created. Currently, the industry uses a 100-size chain piece sorting machine for this purpose.

[0003] However, current 100-chip selectors have the following problems:

[0004] 1. No defective receiving box: The ejected film easily falls to the ground;

[0005] 2. High misjudgment rate: There is about 3% misjudgment, that is, about 3% of good products are rejected as defective products. The proportion of serial numbers containing reversed chips is 51.9%.

[0006] 3. The 100-inch selector uses a bending plate made of 3mm thick sheet metal for stacking and pushing sheets, which is not strong enough and is prone to jamming.

[0007] 4. The speed of a single 100-selector chip selector cannot meet production needs. Utility Model Content

[0037] The discharge conveying mechanism 34 includes a fourth base 38. A discharge conveyor belt motor 29 is fixedly installed at one end of the top side of the fourth base 38.

A switch plate is fixedly installed on the top of the fourth base 38. A step button 27 and an emergency stop button 28 are fixedly installed on the switch plate. The discharge conveyor belt motor 29 drives the conveyor chain 24 to move, thereby driving the conveyor chain 24 to move forward one step distance, thereby driving the stacked pieces on the parallel trough blocks 25 to move forward one step distance. The step button 27 controls the operation of the discharge conveyor belt motor 29, and the emergency stop button 28 controls the discharge conveyor belt motor 29 to stop working urgently.

[0038] A protective cover 30 is fixedly installed on the top of the fourth base 38. The protective cover 30 is located on the side of the fourth base 38 away from the push plate slide 20; the protective cover 30 prevents the chain piece 26 from falling off.

A computer 21 is fixedly mounted on the top of the first bracket. A camera 8 and a camera light source 7 mounted below the camera 8 are fixedly mounted on the top of the second bracket. The camera below the camera 8 faces the top of the sorting conveyor belt 6 through the camera light source 7. The operation panel 22 is fixed to the third base 37 via the universal bracket. The operator operates the equipment through the operation panel 22. The computer 21 is fixed to the third base 37 via the first bracket. The computer 21 displays the recognition results. The camera 8 and the camera light source 7 are fixed to the third base 37 via the second bracket. The camera light source 7 provides illumination for the camera 8. The camera 8 takes pictures, makes judgments, and displays the recognition results on the computer 21.

[0040] The reverse push plate cylinder 9 is positioned opposite one side of the reverse receiving hopper 10, and the lower part of the reverse receiving hopper 10 is positioned corresponding to one end of the return conveyor belt 11. The mixing push plate cylinder 12 is positioned opposite one side of the mixing receiving hopper 13. The reverse push plate cylinder 9 pushes the reverse chain into the reverse receiving hopper 10, and the reverse chain falls from the reverse receiving hopper 10 onto the return conveyor belt 11. The mixing push plate cylinder 12 pushes the mixed material into the mixing receiving hopper 13, where it is stored for subsequent centralized cleaning.

[0041] The output end of the elevator 2 is directly opposite the top of the centrifugal disc 4, the other end of the sorting conveyor belt 6 is connected to one end of the straight vibrating track 5, and one end of the return conveyor belt 11 is located above the hopper 1. The elevator 2 delivers the chain piece 26 raw material to the centrifugal disc 4. The chain piece 26 output by the centrifugal disc 4 moves to the sorting conveyor belt 6 through the straight vibrating track 5. The return conveyor belt 11 returns the chain piece 26 back to the hopper 1.

[0042] A push-out extension plate 23 is fixedly provided on one side of the push-piece slide plate 20. The push-out extension plate 23 is correspondingly provided with the parallel groove block 25. The setting of the push-out extension plate 23 enables the stacked chain pieces 26 to move accurately onto the parallel groove block 25.

[0043] A soundproof cover located outside the centrifugal disc 4 is fixedly installed on the outer side of the top of the second base 36.

[0044] In this embodiment of the application, when the operator presses the start button on the equipment operation panel 22, the elevator motor 3 will drive the elevator 2 to work, the elevator 2 will quantitatively feed the chain pieces 26 in the hopper 1 into the centrifugal disc 4, and the centrifugal disc 4 will lay the chain pieces 26 flat and sequentially enter the linear vibration track 5 while rotating at high speed.

[0045] When the chain link 26 of the linear vibrating track 5 is fed into the sorting conveyor belt 6, the servo motor 15 drives the sorting conveyor belt 6 to run at a constant speed, sending the chain link 26 directly below the camera light source 7. The camera 8 receives the instruction, takes a picture, judges the situation, and displays the recognition result on the computer 21. When the chain link 26 is judged to be reversed, when the chain link 26 runs to the reverse push plate cylinder 9, the reverse push plate cylinder 9 extends and pushes the reverse chain link into the reverse receiving funnel 10. It then falls down the bottom of the reverse receiving funnel 10 into the return conveyor belt 11 and finally flows back to the hopper 1. When the chain link 26 is judged to be mixed due to incorrect logo, incorrect inner diameter, incorrect shape, etc., When the chain link 26 runs to the mixing push plate cylinder 12, the mixing push plate cylinder 12 extends and pushes the mixing chain link into the mixing receiving funnel 13. When the chain link 26 is judged to be OK, when it runs to the pressing cylinder 14, the pressing cylinder 14 extends and presses the chain link 26 into the discharge pipe 16, so that the stacking groove 17 at the outlet of the discharge pipe 16 advances by the thickness of one chain link 26. This continues until the magnetic sensor 18 senses the chain link 26, indicating that the stacking is full. The pushing cylinder 19 extends and drives the pushing slide plate 20 to extend, pushing the stacked pieces in the stacking groove 17 out of the extension plate 23 and onto the parallel trough block 25 of the discharge conveyor belt.

[0046] When the stacked pieces in the stacking groove 17 are pushed onto the parallel trough block 25 of the discharge conveyor belt, the discharge conveyor belt motor 29 drives the conveyor chain 24 to advance one step distance. Alternatively, the step button 27 can be pressed manually to advance one step distance. However, if the discharge conveyor belt needs to be stopped, the emergency stop button 28 should be pressed. The protective cover 30 is mainly to prevent the chain from rolling out during the drive. When the discharge conveyor belt is partially full, it can carry 12 chain pieces 26 with OK surfaces.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
