Connecting columns 13 are arranged between the upper support plates 11 and the lower support plates 12.

[0024] As Figure 3 、 Figure 4 As shown, the lower end surface of the support block 8 has a groove 14. The groove 14 is arranged along the length direction of the belt 7. The width of the groove 14 is greater than the thicknesses of the driving wheel 4 and the driven wheel 5. The limiting rods 9 are arranged on both sides of the opening of the groove 14 and face each other. When at least four limiting rods 9 are simultaneously inserted into the strip-shaped grooves 10, the edge parts of the driving wheel 4 or the driven wheel 5 are located in the groove 14.

[0025] As Figure 2 、 Figure 3 As shown, the conveying assembly further includes a base 15. An adjustment groove 16 is arranged on the base 15. The extending direction of the adjustment groove 16 is the same as the conveying direction of the belt 7. At least one of the driving wheel 4 and the driven wheel 5 is adjustably arranged on the base 15 through an adjustment bracket 17. More specifically, the adjustment bracket 17 in this embodiment is fixed on an adjustment plate 18. A plurality of adjustment holes 19 are arranged on the adjustment plate 18.

[0027] As Figure 6 shown, at least one set of blocking groups 23 is provided on at least one side of the conveying assembly, the blocking groups 23 are located at the positions where the manipulator grabs, and each blocking group 23 includes two blocking cylinders 23a, and the telescopic shafts of the blocking cylinders 23a face the support block 8. When the telescopic shafts of the two blocking cylinders 23a extend, they are located on the front and rear sides of the support block 8 or the tray. In this embodiment, the number of the blocking groups 23 can be set according to the number of the positions where the manipulator grabs, and can be set on the same side or both sides.

[0028] The working principle of this embodiment is as follows:

[0029] The flexible vibrating disk 1 vibrates and scatters the materials (such as breaker contact pieces), the CCD vision camera 2 takes visual pictures of the materials in the flexible vibrating disk 1, identifies the materials that can be grabbed, the multi-axis manipulator 3 grabs the materials in the flexible vibrating disk 1 into the tray, the servo motor 6 drives the driving wheel 4 to rotate, drives the driven wheel 5 to rotate through the tensioned belt 7, the upper belt section drives the support block 8 to move through the gravity of the support block 8 and the friction force generated on the surface of the belt 7, until it moves to the blocking air group 23. The telescopic shafts of the two blocking cylinders 23a of each blocking group 23 extend, and are located on the front and rear sides of the support block 8. The front blocking cylinder 23a fixes the discharging tray or the picking tray, and the rear blocking cylinder 23a is used to block the extrusion of the rear tray on the front tray, ensuring that the next discharging tray or picking tray is the tray behind the current discharging tray or picking tray, avoiding the empty tray or the materials on the tray passing without being picked up. After the materials in the tray are picked up by the manipulator at the position where the manipulator grabs, the telescopic shafts of the two blocking cylinders 23a retract, and the support block 8 drives the tray to continue to move forward. After all the positions where the manipulator grabs have picked up the materials, the support block 8 moves to one end of the belt 7. Then, the support block 8 is conveyed by the belt 7 until all its four limiting rods 9 are caught in the strip-shaped groove 10, and the edge part of the driving wheel 4 or the driven wheel 5 is located in the groove 14. After the belt 7 continuously conveys, the support block 8 is transferred to the lower belt section. At this time, the mounting plane of the mounting tray faces downward, and the four limiting rods 9 face upward. The lower belt section drives the support block 8 to move through the gravity of the support block 8 and the friction force generated on the surface of the belt 7 by the four limiting rods 9, until it moves to the other end of the belt 7, and is transferred to the upper belt section by the cooperation of the limiting rod 9 and the strip-shaped groove 10. At this time, a cycle of the tray is completed.

[0030] The above embodiments are only used to illustrate the technical concept and characteristics of the present utility model. The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it, and it cannot be used to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
