Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a track control device for a production line robotic arm. Background Technology

[0002] Track control devices, through precise trajectory control and flexible motion adjustment, enable the execution of various efficient and accurate tasks. Robotic arms can accurately perform complex tasks according to preset programs and instructions, thereby improving production efficiency, reducing errors and scrap rates, and enhancing product quality.

[0003] During welding, existing laser welding robotic arms produce welding slag that easily detaches from the welded parts and falls into the moving guide rails of the welding arm. A small amount of slag does not affect the normal movement of the laser welding arm, but after long-term use, as the slag accumulates in the guide rails, the movement of the laser welding arm will be affected, and in severe cases, it may even lead to damage to the moving components. Therefore, regular maintenance of the guide rails is required. However, the guide rails on the production line are quite long, and maintenance takes a long time, indirectly affecting the overall production efficiency. Utility Model Content

[0004] To prevent welding slag from accumulating in the guide rails, regular maintenance is required. However, the guide rails on the production line are quite long, making maintenance time-consuming and indirectly affecting overall production efficiency.

[0007] Preferably, the lower end of the laser welding arm moving platform is rotatably connected to a rotating shaft, and a driven gear is fixedly installed at the lower end of the rotating shaft. The driven gear meshes with the drive gear, and the brush plate is fixedly connected to the lower end of the driven gear. The lower end of the brush plate contacts the bottom of the guide rail body.

[0008] Preferably, the bottom surface of the guide rail body is provided with a slag drop outlet, which is located on both sides of the brush plate and above the slag collection box.

A driven gear 14 is fixedly installed at the lower end of the rotating shaft 13. The driven gear 14 meshes with the driving gear 12. The brush plate 15 is fixedly connected to the lower end of the driven gear 14. The lower end of the brush plate 15 contacts the bottom of the guide rail body 1. The bottom surface of the guide rail body 1 is provided with a slag drop outlet 16, which is located on both sides of the brush plate 15 and above the slag collection box 3. In use, the motor 6 is started, which drives the connecting shaft 7 to rotate. The connecting shaft 10 rotates simultaneously. The driving gear is fixedly connected to the lower end of the connecting shaft 10. Simultaneously, the drive gear 14, which is meshed with the drive gear 12, moves at the rack 27, thus enabling the laser welding arm moving platform 2 to move. During the movement, the driven gear 14, which is meshed with the drive gear 12, rotates at the same time. The brush plate 15, which is fixedly connected to the lower end of the driven gear 14, rotates at the same time to sweep the slag that falls on the bottom of the guide rail body 1 to both sides and falls from the slag drop outlets 16 provided on both sides of the bottom of the guide rail body 1. Then, it falls into the slag collection box 3, thus preventing the slag from accumulating at the bottom of the guide rail body 1.

A guide shaft bracket 23 is fixedly installed inside the slag collection box 3, and a stop block 22 is slidably connected to the surface of the guide shaft bracket 23. A spring 24 is sleeved at the end of the guide shaft bracket 23, and the spring 24 is used to reset the stop block 22. A second slag drop outlet 25 is provided on the lower surface of the slag collection box 3, and the stop block 22 is used to block the second slag drop outlet 25. The push plate 17... A top rod 19 is fixedly connected to one side. The length of the top rod 19 is greater than the width of the second slag drop opening 25. The top rod 19 is used to push the stop block 22 to move. When it is necessary to clean the slag in the slag collection box 3, the second motor 20 is started. The second motor 20 drives the threaded rod 21 to rotate. The mounting bracket 18, which is threadedly connected to the threaded rod 21, moves at the same time. The push plate 17, which is fixedly installed on the surface of the mounting bracket 18, pushes the slag in the slag collection box 3 to one side during the movement. The top rod 19 is used to push open the stop block 22. After the stop block 22 is no longer blocked, the slag in the slag collection box 3 is discharged from the second slag drop opening 25. After the push plate 17 returns to its original position, the spring 24 pushes the stop block 22 to reset and block the second slag drop opening 25 again.

[0026] In use, the motor 6 fixedly installed on one side of the mounting plate 5 is started. The motor 6 drives the connecting shaft 7 to rotate. The bevel gear 8 fixedly connected to one end of the connecting shaft 7 simultaneously drives the bevel gear 11 to rotate. The bevel gear 11 is fixedly connected to the upper end of the connecting shaft 10. The connecting shaft 10 rotates at the bearing seat 9 at the same time. The drive gear 12 fixedly connected to the lower end of the connecting shaft 10 moves at the rack 27 at the same time.

[0027] During the movement of the laser welding arm moving platform 2, the driven gear 14, which is meshed with the drive gear 12, rotates simultaneously through the rotating shaft 13. The brush plate 15, which is fixedly connected to the lower end of the driven gear 14, rotates at the same time to sweep the slag that falls on the bottom of the guide rail body 1 to both sides and falls from the slag drop outlets 16 provided on both sides of the bottom of the guide rail body 1. Then it falls into the slag collection box 3, thus preventing the slag from accumulating at the bottom of the guide rail body 1.

[0028] When it is necessary to clean the welding slag in the welding slag collection box 3, start motor 20. Motor 20 drives threaded rod 21 to rotate. Mounting bracket 18, which is threaded to threaded rod 21, moves at the same time. Push plate 17, which is fixedly installed on the surface of mounting bracket 18, pushes the welding slag in welding slag collection box 3 to one side during the movement. Push rod 19 is used to push open stop block 22. After stop block 22 is removed, welding slag in welding slag collection box 3 is discharged from welding slag drop outlet 25. Then motor 20 flips and drives push plate 17 back to its original position. Spring 24 pushes stop block 22 to reset and re-block welding slag drop outlet 25.

[0029] Through the above steps, during the process of the production line robotic arm using the track control device, the driven gear 12 drives the laser welding arm moving platform 2 to move, while the driven gear 14 simultaneously drives the brush plate 15 to rotate, sweeping the slag that falls on the bottom of the guide rail body 1 to both sides, and then dropping it from the slag drop outlets 16 provided on both sides of the bottom of the guide rail body 1, and then dropping it into the slag collection box 3. This prevents the slag from accumulating at the bottom of the guide rail body 1, and completes the collection of slag while cleaning it, greatly reducing the maintenance frequency of the guide rail body 1.
