Description

Technical Field

[0001] This invention relates to the field of welding robot technology, specifically a highly protective collaborative robot automated processing welding device. Background Technology

[0002] Collaborative robots, also known as collaborative industrial robots, are robots designed to interact directly with humans in shared workspaces. Unlike traditional industrial robots that need to be isolated in safety enclosures, collaborative robots are designed with safety, ease of use, and flexibility in mind. Their goal is not to replace humans, but to serve as helpful assistants to humans in completing repetitive, tedious, or ergonomic tasks.

[0003] Welding robots are core equipment in the field of industrial automation and are often referred to as the steel tailors of modern manufacturing. Essentially, they are multi-purpose, reprogrammable automatic control operations in which welding guns or welding torches are mounted on the end flange of an industrial robot, enabling it to automatically perform welding, cutting, or thermal spraying operations.

[0004] Currently, welding robots on the market generate a large amount of fumes during operation because the welding wire produces a lot of smoke and dust. Since most existing fume removal devices are located around the welding robot, a lot of smoke and dust remains at the welding torch, and the surface of the welding torch is covered with fumes. Therefore, existing welding robots cannot achieve the function of fumes absorption and internal circulation cleaning at the welding torch. Therefore, an improved device is needed to address the above problems. Summary of the Invention

[0010] Specifically, the end of the connecting rope away from the central cavity is connected to the connecting crossbar, the second transmission gear meshes with the first gear ring, and the second bevel gear meshes with the first bevel gear.

[0011] Specifically, the front suction head has an air inlet at the side opposite to the connecting pipe, and the inner wall of the air inlet is in contact with the surface of the contact scraper ring.

[0015] The beneficial effects of this invention are:

[0016] First, this invention uses a front suction head located on the outer ring of the welding head, allowing the fumes generated during welding to be absorbed by the front suction head. The front suction head, connecting pipes, and a centralized cavity are interconnected. Simultaneously, the centralized cavity is connected to an external negative pressure device, enabling the front suction head to absorb fumes. Furthermore, air pipes are installed on both sides of the centralized cavity, allowing the fumes to be output in different directions, improving the absorption efficiency of the fumes and completing the work of efficiently suctioning the area near the welding head.

[0017] Second, in this invention, the drive motor, when running, can drive the first gear ring to rotate via the second transmission gear, allowing the second gear ring to intermittently pass through the first transmission gear. This, in turn, causes the first transmission gear and the take-up wheel to rotate intermittently. When the take-up wheel rotates, the connecting rope can pull the connecting crossbar to move, allowing the contact square tube to scrape off the soot adhering to the inner wall of the connecting pipe. Simultaneously, the second spring can reset the contact square tube. When the contact square tube resets, it can move the central base block to contact the contact guide rod, squeezing the contact scraper ring inside the front suction head and moving it towards the front. This allows the contact scraper ring to remove the soot from the inner wall of the front suction head, thus completing the work of cleaning the soot from the front suction head and the inner wall of the connecting pipe.

[0033] The welding head 7 and the air supply pipe 9 are fixedly installed on the top of the collaborative robot 2. The front suction head 12 is fixedly installed on the outer ring of the welding head 7 near the welding wire 8. The central cavity 24 is fixedly installed on the end of the connecting pipe 10 away from the front suction head 12. The end of the connecting rope 29 away from the central cavity 24 is connected to the connecting crossbar 18. The second transmission gear 34 meshes with the first gear ring 27, and the second bevel gear 35 meshes with the first bevel gear 32. The front suction head 12 has an air inlet hole on the side away from the connecting pipe 10, and the inner wall of the air inlet hole is in contact with the surface of the contact scraper ring 15. The interior of the connecting pipe 10 is hollow, and the connecting pipe 10 is interconnected with the front suction head 12 and the central cavity 24. The outer surface of the contact square tube 19 is in contact with the inner wall of the connecting pipe 10. The moving gear 31 is vertically aligned with the second gear ring 28. The tooth distribution angle on the second gear ring 28 is 90°. Through holes are opened on both sides of the centralized cavity 24, and guide air pipes are installed on the through holes. The interior of the centralized cavity 24 is hollow. A square hole adapted to the connecting pipe 10 is opened on the side of the centralized cavity 24 away from the drive motor 25. The connecting rope 29 contacts the outer surface of the guide wheel 11. The contact guide rod 17 is aligned with the central base block 22. The inner ring of the front suction head 12 is in contact with the outer ring surface of the welding head 7. The side of the welding head 7 near the welding wire 8 is flush with the side of the front suction head 12 away from the connecting pipe 10. A gasket is fixedly installed inside the contact scraper ring 15. The ends of the guide rod 13 and the first spring 14 away from the connecting pipe 10 are both connected to the gasket.

[0034] The working principle is as follows: During operation, the collaborative robot 2 drives the welding wire 8 to contact the workpiece to be welded, enabling welding. Simultaneously, the air guide pipes on both sides of the centralized cavity 24 connect to an external negative pressure device. The front suction head 12 is flush with the side of the welding head 7, allowing the external negative pressure device to absorb the welding fumes generated during welding through the front suction head 12. At this time, the front suction head 12 is interconnected with the connecting pipe 10, which in turn is interconnected with the centralized cavity 24. The centralized cavity 24 is interconnected with the air guide pipes, allowing the fumes to be drawn in by the front suction head 12 and finally discharged through the air guide pipes, completing the fume absorption process. Furthermore, the front suction head 12 is positioned near the welding head 7, allowing for the absorption of fumes. Smoke and dust are absorbed promptly to prevent their spread to the surrounding area. Simultaneously, the drive motor 25 can be turned on, rotating the second transmission gear 34. The second transmission gear 34 meshes with the first gear ring 27, allowing it to rotate. The limiting ring 26, located at the bottom of the first gear ring 27, supports its rotation. When the first gear ring 27 rotates, it drives the second gear ring 28 to rotate. When the second gear ring 28 rotates and meshes with the first transmission gear 31, it drives the first transmission gear 31 to rotate. When the first transmission gear 31 rotates, it drives the first bevel gear 32 to rotate. The first bevel gear 32 meshes with the second bevel gear 35, allowing it to pass through the second bevel gear 36. Gear 35 drives take-up reel 33 to rotate simultaneously. When take-up reel 33 rotates, it can pull the connecting crossbar 18 away from the front suction head 12 via connecting rope 29, causing the contact square tube 19 to move simultaneously inside the connecting pipe 10. By having the outer surface of the contact square tube 19 adhere to the inner surface of the connecting pipe 10, the contact square tube 19 can scrape off the tobacco residue adhering to the inner wall of the connecting pipe 10 when it moves. At the same time, the front suction head 12 and the inside of the connecting pipe 10 are in a negative pressure state, so that the scraped tobacco residue can be absorbed and discharged in time. Subsequently, when the second gear ring 28 rotates past the first transmission gear 31, the first transmission gear 31 will lose its meshing force. The elasticity of the second spring 21 will drive the first connecting plate 20 to move quickly. The movement and reset of the contact cylinder 19 allows it to quickly reset inside the connecting pipe 10. Simultaneously, as the contact cylinder 19 resets, it cleans the inner wall of the connecting pipe 10 again, completing a secondary cleaning of the connecting pipe 10. Furthermore, when the contact cylinder 19 resets, it moves the central base block 22 to contact the contact guide rod 17. The contact guide rod 17 is then pressed by the central base block 22, causing the contact scraper ring 15 to move away from the front suction head 12 inside the front suction head 12. The outer surface of the contact scraper ring 15 adheres to the inner wall of the front suction head 12, allowing it to scrape away the grime on the inner wall of the front suction head 12 during displacement, thus completing the cleaning of the grime from the inner wall of the front suction head 12. Subsequently…When the contact tube 19 moves away from the end of the front suction head 12 again, the central base block 22 will disengage from the contact guide rod 17, causing the contact guide rod 17 to lose its squeezing force. At this time, the elasticity of the first spring 14 will pull the contact scraper ring 15 to move and reset. Furthermore, the guide rod 13 is slidably inserted into the interior of the front suction head 12, allowing the contact scraper ring 15 to move linearly inside the front suction head 12, preventing the front suction head 12 from tilting during movement. When the first gear ring 27 rotates, it can drive the second gear ring 28 to pass through multiple first transmission gears 31 in sequence, thereby driving the first transmission gears 31 in different areas to rotate. Thus, the contact tube 19 can intermittently perform cleaning work inside the connecting pipe 10. At the same time, when the contact tube 19 is reset by the second spring 21, the connecting rope 29 can pull the take-up wheel 33 to rotate and reset. And when the take-up wheel 33 rotates, it can be driven by the first... The two bevel gears 35 drive the first bevel gear 32 and the first transmission gear 31 to rotate and reset, facilitating the second gear ring 28 to drive the first transmission gear 31 to rotate again when it passes by the first transmission gear 31. During use, a negative pressure is created inside the front suction head 12, absorbing the fumes generated during welding. Simultaneously, the drive motor 25, while running, drives the second gear ring 28 to intermittently pass by the first transmission gear 31, allowing the connecting rope 29 to pull the contact square tube 19 along the inner wall of the connecting pipe 10, removing the fumes from the inner wall of the connecting pipe 10. After resetting, the contact square tube 19 can move the contact scraper ring 15 forward via the contact guide rod 17, allowing the contact scraper ring 15 to scrape off the fumes adhering to the inner wall of the front suction head 12. Furthermore, the negative pressure inside both the front suction head 12 and the connecting pipe 10 ensures that the scraped fumes are absorbed promptly, completing the operation.
