The tightening mechanism 500 is used to tighten threaded components on the workpieces to be processed, and the marking mechanism 600 is used to engrave a two-dimensional code on a marking area on the workpieces 20 to be processed.

[0041] The tightening and marking device 10 described in the embodiment of the present application connects the two ends and the two sides of the first conveying assembly 200 and the second conveying assembly 300 with the transfer mechanisms 400, so that the trays 100 on which the workpieces 20 to be processed are placed can be moved in a cycle under the driving of the first conveying assembly 200, the second conveying assembly 300 and the transfer mechanisms 400. After the workpieces 20 to be processed are transferred to the trays 100 at the feeding position 200A, the workpieces 20 to be processed are conveyed to the processing position 200B by the first conveying assembly 200. The tightening mechanism 500 on the processing position 200B tightens the threaded components of the workpieces 20 to be processed, and then the marking mechanism 600 marks an identification, thereby completing the processing. After the workpieces processed are discharged, the trays 100 enter the transfer mechanisms 400 from the first output end 202, and then the transfer mechanisms 400 output the trays 100 to the second input end 301 of the second conveying assembly 300, so that the trays 100 flow back to the other transfer mechanisms 400 through the second conveying assembly 300, and then the other transfer mechanisms 400 put the trays 100 into the first conveying assembly 200 again. The whole processing process can be completed automatically.

[0042] The screwing and marking device 10 provided by the embodiment of the present application forms a conveying loop through the first conveying assembly 200, the second conveying assembly 300 and the transfer mechanism 400, and the tray 100 can be driven to move in the conveying loop, so that the steps of feeding, processing and discharging can be completed. In addition, the screwing and marking device 10 can be used in cooperation with other automatic equipment such as a mechanical hand during feeding and discharging, so that the degree of automation is further improved, the work efficiency is improved, and the advantages of high efficiency and high processing quality are achieved.

[0043] In combination Figure 3 as shown, Figure 3 The structure of the material taking rack 700 of the screwing and marking device 10 in the embodiment of the present application is shown. In some embodiments, the screwing and marking device 10 further includes the material taking rack 700, which is arranged on one side of the first conveying assembly 200. The material taking rack 700 includes a plurality of placing boxes 710, a plurality of indicator lights 720 and a plurality of pickup sensors 730. The material taking rack 700 is provided with a plurality of placing cavities, and each placing cavity is provided with a pickup opening 700A on the side close to the first conveying assembly 200. The placing boxes 710 are arranged in one-to-one correspondence in the placing cavities, and the pickup sensors 730 and the indicator lights 720 are arranged in one-to-one correspondence in the pickup openings 700A. The pickup sensors 730 and the indicator lights 720 are electrically connected. The material taking rack 700 is arranged on one side of the first conveying assembly 200, specifically on one side of the feeding position 200A. Different placing boxes 710 on the material taking rack 700 can be used to place various mounting components of the workpiece 20 to be processed, and the mounting components can be threaded components. After the workpiece 20 to be processed is fed to the tray 100, the worker can take the mounting components from the placing boxes 710 through the pickup openings 700A and mount the mounting components on the workpiece 20 to be processed. The placing boxes 710 are also provided with the pickup sensors 730 and the indicator lights 720 in correspondence. When the worker takes the mounting components from the placing boxes 710, the pickup sensor 730 corresponding to the placing box 710 detects the pickup action, and the corresponding indicator light 720 is extinguished or turned on, so that whether the mounting components have been used can be quickly judged from the state of the indicator light 720, and the mounting components are convenient to use.

By setting the placement box 710 to be downwardly inclined on the side close to the pickup port 700A, and further providing the roller 711 on the pickup rack 700 on the bottom surface of the placement box 710, when the placement box 710 is placed on the roller 711, the placement box 710 and the mounting components in the placement box 710 automatically slide to the side close to the pickup port 700A under the action of gravity, thereby facilitating the worker to take the mounting components from the placement box 710, and improving the work efficiency.

[0045] Further, the pickup rack is further provided with a recovery cavity, the bottom surface of the recovery cavity is higher on the side close to the pickup port 700A than on the side away from the pickup port 700A, and the bottom of the recovery cavity is also provided with a roller 711, and the placement box 710 is movably placed on the roller 711. By setting the recovery cavity, when the mounting components in the placement cavity are used up, the placement box 710 can be placed in the recovery cavity, so that the placement box 710 is slid to the side opposite to the first conveying assembly 200, and the placement box 710 can be conveniently replenished with mounting components on the side opposite to the first conveying assembly 200, and after the replenishment is completed, the placement box 710 is re-placed in the placement cavity.

The output end of the lifting drive unit 430 is connected with the lifting support 420. The conveying assembly 440 is used to receive the tray 100 conveyed by the first conveying assembly 200 and then transfer the tray 100 to the second conveying assembly 300, or receive the tray 100 conveyed by the second conveying assembly 300 and then transfer the tray 100 to the first conveying assembly 200. The lifting rail 410 is arranged to make the lifting support 420 slide on the lifting rail 410. Specifically, the lifting drive unit 430 controls the lifting support 420 to lift or lower. The conveying assembly 440 is arranged on the lifting support 420, that is, the lifting support 420 drives the conveying assembly 440 to move to the height position corresponding to the first conveying assembly 200 and the second conveying assembly 300, so as to receive or output the tray 100 to the first conveying assembly 200 and the second conveying assembly 300, complete the transfer of the tray 100, and realize the automatic recycling of the tray 100.

[0048] In an exemplary embodiment, as shown in Figure 2 The conveying assembly 440 connected with the first output end 202 can also serve as a discharging position of the tray 100.

The conveying belt 441 can be connected with the first conveying assembly 200 or the second conveying assembly 300 under the driving of the lifting support 420, so as to transfer the tray 100 from the conveying assembly to the conveying belt 441 or from the conveying belt 441 to the conveying assembly, thereby realizing the switching of the tray 100 between the first conveying assembly 200 and the second conveying assembly 300, and realizing the automatic recycling of the tray 100 to the feeding position 200A after the tray 100 is used up, which has high automation degree.

[0050] In an exemplary embodiment, as shown in Figure 4As shown, the conveying assembly 440 also includes a sensing sensor 444, which is disposed on one side of the conveyor belt 441. The sensing sensor 444 is used to detect whether the tray 100 is located in the conveying assembly 440. By setting the sensing sensor 444, the lifting and lowering is only started when the tray 100 is correctly placed on the conveyor belt 441, thus avoiding the situation where the tray 100 falls off the conveyor belt 441 during the lifting and lowering process and improving the stability of the device.
