[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1-6 The present invention shows a conveying track for automobile parts of an automobile production line, which includes an upper mounting frame 1 and a lower mounting frame 2. The top of the lower mounting frame 2 is fixedly connected to a driving frame 3. The top of the driving frame 3 is rotatably connected to two driving shafts 4. A gear belt 5 is rotatably connected between the two driving shafts 4. The bottom end of the driving frame 3 is fixedly connected to a driving machine 6. The output end of the driving machine 6 is fixedly connected to the bottom end of one of the driving shafts 4. The bottom end of the upper mounting frame 1 is fixedly connected to a track 7 matching the gear belt 5. A plurality of evenly distributed hangers are arranged on the lower side of the track 7. The hangers include a connecting plate 8. Both ends of the connecting plate 8 are fixedly connected to a wheel frame 801. One end of the wheel frame 801 is fixedly connected to a roller 802, and the roller 802 is rotatably connected to the track 7. A travel motor 803 is fixedly connected to the middle of the connecting plate 8, and a travel gear 804 is fixedly connected to the output end of the travel motor 803. The travel gear 804 is meshed with the gear belt 5. A hook 805 is fixedly connected to the bottom end of the connecting plate 8, and a connector 806 is fixedly connected to one end of the hook 805. It also includes a loading area 11, a unloading area 12 and a plurality of robot arm stations 13. The loading area 11 and the unloading area 12 are respectively located on one side of the two driving shafts 4, and the plurality of robot arm stations 13 are located on one side of the gear belt 5.

[0025] When the travel motor 803 is started, it can drive the travel gear 804 to rotate. When the travel gear 804 rotates, it drives the sling to move along the gear belt 5. When the sling moves to the position of the loading area 11, the auto parts are installed on the connector 806. When the sling moves to one side of the multiple robot arm stations 13, the robot arm stations 13 assemble the auto parts. When the sling moves to the position of the unloading area 12, the assembled auto parts are removed. The above reciprocating movements can complete the transportation of auto parts.

[0026] At the same time, the driving machine 6 starts to drive the gear belt 5 through the driving shaft 4. When the transmission speed of the gear belt 5 is less than the rotation speed of the traveling gear 804, and the transmission direction of the gear belt 5 is opposite to the rotation direction of the traveling gear 804, the relative movement speed of the sling will slow down. When the rotation speed of the traveling gear 804 is balanced with the rotation speed of the gear belt 5, the sling will no longer move along the gear belt 5. When the automotive accessories are installed, disassembled and assembled at the loading area 11, the unloading area 12 and the robot arm station 13, the rotation speed of the gear belt 5 is adjusted by the driving machine 6 and the rotation speed of the traveling gear 804 is adjusted by the traveling motor 803, so that the sling can be suspended in the loading area 11, the unloading area 12 and the robot arm station 13 to facilitate the installation, disassembly and assembly of the automotive accessories.

[0027] Through the above-mentioned settings, the conveyor track can transport automobile parts to different locations for assembly without stopping, which greatly reduces the instability factor caused by shaking due to frequent shutdowns and improves the stability and positioning accuracy of transportation. At the same time, by adjusting the rotation speed of the travel motor 803 on multiple hangers, the distance between multiple hangers can be changed, which can adapt to frequently changing production needs and no longer limit the positions of multiple robot arm stations 13, further meeting different production needs.

[0028] The gear belt 5 is composed of a magnetic belt 501 and a ruler belt 502, and the ruler belt 502 is located on the outside of the magnetic belt 501. An inner cavity 8041 is opened inside the traveling gear 804, and a magnet ring 8042 is fixedly connected to the inner cavity 8041. Through the above arrangement, the gear belt 5 and the traveling gear 804 can be better fitted together, thereby improving the stability of the meshing between the traveling gear 804 and the gear belt 5.

[0029] The second implementation method:

[0030] Figure 1-4 The present invention shows a conveying track for automobile parts of an automobile production line. Different from the first embodiment, an oil pump 9 is fixedly connected to the bottom end of the lower mounting frame 2, and oil pipes 18 are fixedly connected between the two ends of the oil pump 9 and the two ends of the driving shaft 4, and a filter 10 is installed on the outer wall of one of the oil pipes 18. The interior of the driving frame 3 is filled with lubricating oil, and a top groove 301 is opened at the top of the driving frame 3, and the output end of the travel motor 803 is located on the inner side of the top groove 301.

[0031] Through the above-mentioned arrangement, it can play a role in lubrication between the gear belt 5 and the traveling gear 804, thereby improving the stability of the traveling gear 804 during movement. At the same time, when the oil pump 9 is started, the lubricating oil can circulate inside the drive shaft 4, and during the flow process, the filter 10 can filter impurities in the lubricating oil.

[0032] One end of the connecting plate 8 is fixedly connected to an upper speed sensor 14, one end of the upper speed sensor 14 is located on one side of the output end of the walking motor 803, the bottom end of the driving shaft 4 is fixedly connected to a lower speed sensor 15, one end of the lower speed sensor 15 is located on one side of the output end of the driving machine 6, and also includes a speed control module, the upper speed sensor 14 and the lower speed sensor 15 are both electrically connected to the speed control module, and the walking motor 803 and the driving machine 6 are both electrically connected to the speed control module.

[0033] Through the above settings, the speed control module can obtain the speed of the travel motor 803 and the drive motor 6 through the upper speed sensor 14 and the lower speed sensor 15, and then control the rotation speed of the drive motor 6 and the travel motor 803 according to the movement requirements of different hanging objects.

[0034] A UWB tag 16 is fixedly connected to one end of the connecting plate 8, and a plurality of UWB base stations 17 are fixedly connected to the bottom end of the upper mounting frame 1. The UWB tag 16 and the UWB base station 17 are electrically connected. Through the above arrangement, the plurality of UWB base stations 17 can obtain the positions of the plurality of hangers through the UWB tag 16, and thus control the distance between the plurality of hangers.

[0035] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
