[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figures 1-5 As shown, the track-mounted welding robot according to an embodiment of this application includes:

[0029] The support rail 1 has a guide rail groove 4 inside. The bottom of the guide rail groove 4 is set with a sloping structure to prevent dust or welding slag from falling into the guide rail groove 4 and making it difficult to clean. Under the action of gravity, some welding slag will slide into the support rail 1. An embedding groove 5 is opened on one side of the support rail 1. A power supply base plate 6 is fixedly installed in the embedding groove 5. By setting the power supply base plate 6 on one side of the support rail 1, sliding power can be achieved. That is, during the horizontal movement of the robot body, power can be directly drawn from the power supply base plate 6 without dragging cables. This structural design will not interfere with the welding action of the robot body. The robot will operate more smoothly and will not cause disorder.

[0030] Robot arm assembly 2 includes a robot and a robot base 7. A base frame 17 is fixedly connected to the bottom of the robot base 7, and extension rods 19 are fixedly connected to both sides of the base frame 17. The robot is mounted on the upper part of the robot base 7, which is slidably mounted on the upper part of the support rail 1. A driving component, which mates with the rail groove 4, is provided at the bottom of the robot base 7. The driving component includes auxiliary balancing guide wheels 16 and a drive motor 18. Two sets of auxiliary balancing guide wheels 16 are symmetrically arranged and rotatably mounted on both sides of the bottom of the robot base 7. The auxiliary balancing guide wheels 16 rotate and abut against the upper part of the support rail 1, allowing the robot base 7 to bend on the upper part of the support rail 1. The robot base 7 can bend depending on the equipment being used. Two sets of auxiliary balancing guide wheels 16 work together to turn the robot base 7, allowing it to move along the curved support rail 1. CNC intelligent auxiliary guide wheels can be used to increase the smoothness of the overall curved movement. The drive motor 18 is fixedly installed in the middle of the base frame 17. The drive motor 18 can be a hub motor, which drives the rollers 20 within the guide rail groove 4 via shafts fixed at both ends. With the support of the two sets of auxiliary balancing guide wheels 16, the robot base 7 will not tilt. Both ends of the drive motor 18 pass through the base frame 17 and are rotatably mounted with rollers 20. Wheel 20 is rotatably mounted in guide rail groove 4. A sliding hole 12 is provided on one side of the robot base 7, with one end of the sliding hole 12 connected to a circular hole 8. An electrical component, which mates with the power supply base plate 6, is electrically connected to one side of the robot base 7. The electrical component includes an inner conductive rod 9, a return spring 10, an outer conductive rod 13, and a conductive contact block 15. The inner end of the inner conductive rod 9 is slidably mounted in the sliding hole 12, and extends into the circular hole 8. The return spring 10 is sleeved on the outside of the inner conductive rod 9, with one end of the return spring 10 abutting against the inside of the circular hole 8. The outer conductive rod 13 is fixedly connected to the outer end of the inner conductive rod 9, and the conductive contact block 15 is fixedly connected to the other end of the outer conductive rod 13. The conductive contact block 15 is electrically connected to the power supply base plate 6. When the equipment is powered on, the inner conductive rod 9 can be pulled outward. At this time, the return spring 10 generates a return force. Under the action of the return spring 10, the conductive contact block 15 will be in tight contact with the power supply base plate 6, and there will be no loose contact. The contact position between the conductive contact block 15 and the power supply base plate 6 is set as an arc to facilitate contact at the bend. If loose contact occurs between the conductive contact block 15 and the power supply base plate 6, the insulating fastening collar 11 can be rotated to make the return spring 10 generate a greater return force on the inner conductive rod 9, thereby increasing the tightness of the contact between the conductive contact block 15 and the power supply base plate 6. However, the conductive contact block 15 will inevitably wear during the sliding process. An insulating fastening collar 11 is provided inside one end of the circular hole 8.An insulating fastening collar 11 is threaded onto the inner end of the inner conductive rod 9. The port of the insulating fastening collar 11 abuts against the other end of the return spring 10. A limiting block 14 is fixedly connected to the outer end of the inner conductive rod 9. The limiting block 14 abuts against the opening of the sliding hole 12, ultimately limiting the depth of the outer end of the inner conductive rod 9 into the sliding hole 12. If the limiting block 14 is tightly fitted to the opening of the sliding hole 12, and the conductive contact block 15 cannot contact the power supply base plate 6, the inner conductive rod 9, outer conductive rod 13, and conductive contact block 15 need to be replaced. Because the conductive contact block 15 may wear and become thinner, when not in use, the conductive contact block 15 can be flipped upwards, thus preventing it from contacting the power supply base plate 6 and achieving a complete or temporary power cut-off for the entire device.

[0031] Cleaning component 3 includes a main scraper 21 and a secondary scraper 22. Both the main scraper 21 and the secondary scraper 22 are located below the robot base 7 and are fixedly connected to the bottom of the robot base 7. Both the main scraper 21 and the secondary scraper 22 are slidably disposed within the support guide rail 1 and are fixedly connected to the extension rod 19 by fixing bolts. The main scraper 21 is slidably disposed within the guide rail groove 4, at the inner bottom of the support guide rail 1. During the operation of the robot base 7, the main scraper 21 can clean the inner bottom of the support guide rail 1. Welding slag or dust is cleaned to prevent the accumulation of welding slag particles on the inner bottom of the support rail 1, which would make it difficult to clean later. The secondary scraper 22 can scrape or clean the welding slag particles in the rail groove 4, avoiding affecting the operation of the roller 20. A baffle 23 is fixedly connected to the gap between the main scraper 21 and the secondary scraper 22. Since the secondary scraper 22 cleans first, the main scraper 21 can easily cause welding slag to bounce when cleaning the bottom of the support rail 1. The baffle 23 can prevent welding slag from bouncing into the gap between the main scraper 21 and the secondary scraper 22.

[0032] Specifically, the working principle of this track-type welding robot is as follows: The support rail 1 has an internal guide rail groove 4 with a sloping bottom to prevent dust or welding slag from accumulating and becoming difficult to clean. A power supply base plate 6 is positioned on one side of the support rail 1, allowing for sliding power extraction. This means that during the robot's horizontal movement, power can be directly drawn from the power supply base plate 6 without dragging cables. This structural design also avoids interfering with the robot's welding actions, resulting in smoother operation and preventing erratic movements. Two sets of auxiliary balancing guide wheels 16 are symmetrically arranged and rotatably mounted on both sides of the robot base 7's bottom. The auxiliary balancing guide wheels 16 rotate and abut against the upper part of the support rail 1, driving the robot base 7 to bend and turn on the upper part of the support rail 1. The drive motor 18 can be a hub motor, allowing for the fixing of two... The shaft at the end drives the roller 20 to rotate in the guide rail groove 4. When the equipment is powered on, the inner conductive rod 9 can be pulled outward. At this time, the return spring 10 generates a return force. Under the action of the return spring 10, the conductive contact block 15 will be in tight contact with the power supply base plate 6, and there will be no loose contact. If there is loose contact between the conductive contact block 15 and the power supply base plate 6, the insulating fastening collar 11 can be rotated to make the return spring 10 generate a greater return force on the inner conductive rod 9, thereby increasing the tightness of the contact between the conductive contact block 15 and the power supply base plate 6. Under the operation of the robot base 7, the main scraper 21 can clean the welding slag or dust on the inner bottom of the support guide rail 1, avoiding the accumulation of welding slag particles on the inner bottom of the support guide rail 1, which will make it difficult to clean later. The auxiliary scraper 22 can scrape or clean the welding slag particles in the guide rail groove 4, avoiding affecting the operation of the roller 20.
