Technical Field

[0001] This utility model relates to the field of welding robot technology, specifically a lightweight mobile robot. Background Technology

[0002] Welding robots are automated devices used to perform welding tasks without direct human operation. They play an important role in modern manufacturing, improving production efficiency, quality, and safety while reducing costs and labor requirements, and are therefore widely used and favored.

[0003] For example, utility model patent CN222448915U discloses a lightweight mobile welding robot, including a base plate. A robotic arm is fixedly connected to the top left end of the base plate, and a welder is fixedly connected to the bottom of the robotic arm. A motor is fixedly connected to the inner wall of the base plate, and a rotating plate is fixedly connected to the drive end of the motor. Connecting plates are rotatably connected to both sides of the top of the rotating plate. A pulling plate is rotatably connected to the other end of the connecting plate. A moving plate is fixedly connected to the end of the pulling plate away from the connecting plate. A support plate is fixedly connected to the top of the moving plate, and a clamping plate is fixedly connected to the top of the support plate. This invention achieves the effect of clamping and fixing the plate to be welded, avoiding shaking during the welding process and affecting the final welding result. It can protect the welding process while collecting the debris generated during welding. However, there is a problem that it is inconvenient to provide stable support for the base plate during the use of the welding robot, which will cause the welding robot to shake during operation. In the end, the welding robot will cause the base plate to shake, resulting in the displacement of the workpiece on the base plate and reducing the welding efficiency. To address this, we propose a lightweight mobile robot. Utility Model Content

The movable base 1 is fixedly installed at the lower end of the support plate 619.

[0023] Specifically, when the main electric push rod 62 is activated, the output end of the main electric push rod 62 drives the bending strip 67 to move downward.

[0025] Specifically, during the downward movement of the main electric push rod 62, the main electric push rod 62 also drives the L-shaped moving bar 63 to move downward. The L-shaped moving bar 63 drives the stepper motor 64, the first rotating shaft 65, and the first gear 66 to move downward. When the first gear 66 meshes with the third gear 614, the power supply to the main electric push rod 62 is disconnected. Next, the stepper motor 64 is started. The output end of the stepper motor 64 drives the first rotating shaft 65 to rotate. The first rotating shaft 65 drives the first gear 66 to rotate. The first gear 66 drives the third gear 614 to rotate. The third gear 614 drives the follower shaft 613 to rotate. At this time, the third gear 614 drives the fourth gear 615 to rotate. The fourth gear 615 drives the main rotating shaft 616 to rotate, which in turn drives the auxiliary rotating shaft 620 to rotate via the belt 618.

[0033] Specifically, ensure that the main rotating shaft 616 and the auxiliary rotating shaft 620 do not interfere with the movable base 1 during rotation.

[0034] Working principle: When the main electric push rod 62 is activated, its output end drives the bending strip 67 to move downwards. The bending strip 67 drives the first rack 68 to move downwards. At this time, the first rack 68 drives the second gear 69 to rotate. The second gear 69 drives the second rack 610 to move upwards. The second rack 610 drives the slide bar 611 to move upwards. The slide bar 611 slides within the slide groove 7. The slide bar 611 drives the support base 612 to move upwards, moving the support base 612 away from the ground. During the downward movement of the main electric push rod 62, it also drives the L-shaped moving strip 63 to move downwards. The L-shaped moving strip 63 drives the stepper motor. 64. The first rotating shaft 65 and the first gear 66 move downwards. When the first gear 66 meshes with the third gear 614, the power supply to the main electric push rod 62 is disconnected. Next, the stepper motor 64 is started. The output of the stepper motor 64 drives the first rotating shaft 65 to rotate. The first rotating shaft 65 drives the first gear 66 to rotate. The first gear 66 drives the third gear 614 to rotate. The third gear 614 drives the follower shaft 613 to rotate. At this time, the third gear 614 drives the fourth gear 615 to rotate. The fourth gear 615 drives the main rotating shaft 616 to rotate, which in turn drives the auxiliary rotating shaft 620 to rotate via the belt 618.
