Description

Technical Field

[0001] The present invention relates to the technical field of plate welding, and more specifically, to an automatic feeding type welding robot for plate processing. Background Art

[0002] A welding robot is an automated equipment specially used for welding operations. It is a type of industrial robot. Welding robots are widely used in automobile manufacturing, engineering machinery, aerospace, shipbuilding, rail transportation, steel structure, power equipment and other industries.

[0003] Chinese patent application number CN202410461690.4 discloses an automatic metal sheet welding robot, including: an external moving part, a grinding part, a moving double-layer part, and a welding part. The moving double-layer part is fixedly installed at the rear end position of the grinding part, and the welding part is located at the rear end position of the moving double-layer part; the moving double-layer part includes: a lower transmission structure and an upper transmission structure. There are two lower transmission structures, and the two lower transmission structures are symmetrically distributed. The upper transmission structure is located above the lower transmission structure. The lower metal sheet is moved by the lower transmission structure, and then the metal sheet is rotated by a certain angle by the upper transmission structure. Then, the two metal sheets are driven to move at the same time by the lower transmission structure and the upper transmission structure, so that the two metal sheets are bonded together.

[0004] In the above technical scheme, the diversity of welding equipment is improved and the practicality of welding equipment is increased. However, in traditional plate feeding welding, the usual practice is to parallelly connect the two plates to be welded and then use a welding robot to weld them. In actual life, sometimes it is necessary to connect the two plates and weld them at different angles. In this case, the traditional method often requires personnel to use a slope support frame to support the plate to be welded so that it can reach the required welding angle. Since the slope plate has a certain slope, this will cause the plate to be welded to be unstable during the welding process, thereby affecting the welding quality of the plate by the welding robot. Secondly, when it is necessary to weld the two plates to be welded into formed parts with different angles, the operator needs to replace the slope frame. This process is cumbersome, time-consuming and laborious, which not only increases labor intensity but also reduces production efficiency. Summary of the invention

When the angle between the movements of the two plates 41 to be welded corresponds to the required welding angle, the welding robot body 2 carries the welding head 3 to weld the two plates 41 to be welded. Compared with the traditional welding device, it can not only adjust the welding angle between the two plates 41 to be welded, but also increase the welding The versatility of the equipment also ensures stability during the welding process, thereby ensuring the welding quality of the sheet 41 to be welded. The welding process is convenient, fast, time-saving and labor-saving, and improves the production efficiency of the formed sheet 41 to be welded; the telescopic device 18 is extended to move the slider 7 downward, so that the first rotating shaft 8 moves with the expansion roller 10 toward the surface of the sheet 41 to be welded.

At this time, the two plates 41 to be welded continue to move toward each other.

[0047] A motor 17 is fixedly mounted on the other side surface of the two arc blocks 5. The output end of the motor 17 is fixedly connected to the second rotating shaft 9. The motor 17 is a conventional electric motor in the prior art. The rotation of the motor 17 enables the plate 41 to be welded to be fed.

The surface of the rotating shaft 27 is provided with a roller 28 that contacts the inner bottom surface of the lifting frame 20. When the roller 28 rolls on the inner bottom surface of the lifting frame 20, the rotating shaft 27 moves in the open-wire groove 26. The roller 28 is rotatably connected to the bracket 25 through the rotating shaft 27 to ensure that the sliding rod 21 slides stably on the surface of the lifting frame 20.

[0050] A support plate 23 is fixedly installed on the side surface of the base 1, and an electric telescopic rod 24 is fixedly installed on the surface of the support plate 23.

[0051] A support 29 is fixedly installed in the middle of the surface of the base 1, the bottom surface of the ring slide 4 is fixedly connected to the surface of one end of the support 29, and a frame seat 30 is fixedly installed on the side surface of the support plate 23. The surface of the frame seat 30 is fixedly connected to the bottom surface of the welding robot body 2, and the base 1, the frame seat 30 and the bottom surface of the frame seat 30 are in contact with the ground. An outer arc groove 31 is provided on the outer surface of the ring slide 4, and two matching follower frames 32 are correspondingly slidably connected to the inside of the outer arc groove 31. One end of the two follower frames 32 are respectively fixedly connected to the outer surfaces of the two arc blocks 5, and the side surfaces of the two follower frames 32 are fixedly installed with clamping devices 33. The clamping device 33 is a conventional hydraulic clamp in the prior art, which is used to clamp and fix the plate 41 to be welded. When the two plates 41 to be welded are welded at an angle, the plate 41 to be welded is prevented from sliding down under the action of its own weight.

[0052] An angle ruler 34 is fixedly installed on the surface of the ring slide 4, and an angle sensor 35 is fixedly installed on the other side surfaces of the two arc blocks 5. The angle sensor 35 is a conventional angle sensing device in the prior art.

When the angle between the movements of the two plates 41 to be welded corresponds to the required welding angle, the electric telescopic rod 24 stops working.

[0053] Two slide rails 38 are fixedly installed on the surface of the base 1, and two matching mobile racks 39 are slidably connected to the surfaces of the two slide rails 38 respectively. A feeding rack 40 is fixedly installed on the surface of the mobile rack 39, and a plate 41 to be welded is placed on the surface of the feeding rack 40. An intelligent mobile vehicle 42 for driving the movement of the mobile rack 39 is fixedly installed on the bottom surface of the mobile rack 39. The intelligent mobile vehicle 42 is a conventional remote-controlled driven vehicle in the prior art, and is used for automatically feeding the plate 41 to be welded.

[0054] The use steps of the present invention are as follows: when the automatic feeding welding robot for plate processing is in use, when two plates 41 to be welded need to be butt-welded in parallel, the two plates 41 to be welded are first hoisted to the surface of the feeding rack 40 by external hoisting equipment, and the plate 41 to be welded on the side close to the ring slide 4 extends out of the feeding rack 40, and at this time, the two intelligent mobile vehicles 42 move towards each other and carry the two plates 41 to be welded toward the ring slide 4. In the initial state, the clamping device 33, the expansion roller 10 and the rotating roller 11 are in the same horizontal plane as the feeding rack 40. After the two plates 41 to be welded move towards each other and pass through the clamping device 33, when they enter between the expansion roller 10 and the rotating roller 11, the bottom surface of the plate 41 to be welded contacts the surface of the rotating roller 11, and the intelligent mobile vehicle 42 stops running. At this time, the telescopic device 18 extends and moves the slider 7 downward, so that the first rotating shaft 8 moves and moves the expansion roller 10 toward the surface of the plate 41 to be welded. When the expansion frame 13 contacts the surface of the plate 41 to be welded, as the telescopic device 18 continues to extend, the expansion frame 13 moves toward the inside of the slot 12 to squeeze the elastic member 14. When the first rotating shaft 8 moves and moves the slave gear 15 to engage with the driving wheel 16, the telescopic device 18 stops working, the intelligent mobile vehicle 42 is reset, and the motor 17 rotates and drives the second rotating shaft 9 to rotate, thereby rotating the roller 11. At this time, the two plates 41 to be welded continue to move toward each other. When the welding distance between the two plates 41 to be welded is adapted, the motor 17 is stopped, and then the clamping device 33 works to fix the plate 41 to be welded. At this time, the welding robot body 2 The welding head 3 is used to weld two plates 41 to be welded. When the two plates 41 to be welded are welded at different angles, according to the welding angle required by the two plates 41 to be welded, the electric telescopic rod 24 is telescopic to move the lifting frame 20, so that the movement of the two slide bars 21 drives the movement of the rotating rod 19, and then the two arc blocks 5 slide in the ring slide 4, and the rotating rod 19 squeezes the slide bar 21. At this time, the slide bar 21 rolls on the lifting frame 20 with the roller 28, and the two arc blocks 5 move with the expansion roller 10, the rotating roller 11, the follower frame 32 and the clamping device 33, so that the two plates 41 to be welded move. During the movement of the two arc blocks 5, the angle sensor 35 follows the movement of the arc blocks 5, and the angle sensor 35 real-time adjusts the angle ruler 3 4 is used for identification. When the angle between the movements of the two plates 41 to be welded corresponds to the required welding angle (note that the two arc blocks 5 move around the center of the circle, and the two plates 41 to be welded follow the movement of the two arc blocks 5, so the welding distance of the two plates 41 to be welded is also applicable to the welding distance of the welding robot body 2), the electric telescopic rod 24 is stopped, and the welding robot body 2 welds the two plates 41 to be welded with the welding head 3. After the welding is completed, the clamping device 33 is reset to stop clamping the plates 41 to be welded, and the expansion roller 10 is reset by movement. At this time, the molded part can be removed by external lifting equipment. According to the required welding angle of the two plates 41 to be welded, the lifting frame 20 moves so that the two slide bars 21 move and drive the rotating rod 19 to move.Then, the two arc blocks 5 slide in the ring slide 4, and the movement of the two arc blocks 5 brings the expansion roller 10, the rotating roller 11, the follower frame 32 and the clamping device 33 to move, so that the two plates 41 to be welded move. When the angle between the movements of the two plates 41 to be welded corresponds to the required welding angle, the welding robot body 2 brings the welding head 3 to weld the two plates 41 to be welded. Compared with the traditional welding device, it can not only adjust the welding angle between the two plates 41 to be welded, increase the versatility of the welding equipment, but also ensure the stability of the welding process. The welding quality of the plate 41 to be welded is ensured, and the welding process is convenient, fast, time-saving and labor-saving, which improves the production efficiency of the formed plate 41 to be welded; the expansion device 18 extends and moves the slider 7 downward, so that the first rotating shaft 8 moves and moves the expansion roller 10 toward the surface of the plate 41 to be welded. When the expansion frame 13 contacts the surface of the plate 41 to be welded, as the expansion device 18 continues to extend, the expansion frame 13 moves toward the inside of the notch 12 to squeeze the elastic member 14, and the plates 41 to be welded with different thicknesses can be fed and welded, thereby increasing the practicality of the welding equipment.

By arranging the through plate 45 on one side of the expansion roller 10 and the rotating roller 11, the two plates 41 to be welded move toward each other through the clamping device 33 and enter between the expansion roller 10 and the rotating roller 11. As the intelligent mobile vehicle 42 continues to move, the plates 41 to be welded enter the through plate 45, and the ends of the plates 41 to be welded squeeze the two protective rotating plates 48. The two protective rotating plates 48 are in contact with the surfaces of the plates 41 to be welded under the action of the spring shaft 47, so as to protect the surfaces of the two plates 41 to be welded and prevent welding slag from scattering onto the surfaces of the plates 41 to be welded, thereby ensuring the beauty of the molded parts.

[0056] The use steps of the present invention are as follows: when the automatic feeding welding robot for plate processing is in use, when the welding robot body 2 carries the welding head 3 to weld two plates 41 to be welded, high-temperature welding slag will be generated at the existing welding point, and these welding slag will be scattered on the surfaces on both sides of the welding point of the plates 41 to be welded, thereby affecting the appearance of the finished parts. In serious cases, the molded parts need to be further polished. By arranging a through plate 45 on one side of the expansion roller 10 and the rotating roller 11, the two plates 41 to be welded move toward each other through the clamping device 33 and enter between the expansion roller 10 and the rotating roller 11. As the intelligent mobile vehicle 42 continues to move, the plates 41 to be welded enter the through plate 45 at this time, and the ends of the plates 41 to be welded squeeze the two protective rotating plates 48. The two protective rotating plates 48 are in contact with the surface of the plates 41 to be welded under the action of the spring shaft 47 (the spring shaft 47 is smaller than the movement force of the plates 41 to be welded). When a small amount of the sheet 41 to be welded leaks out of the through plate 45, the sheet 41 to be welded stops moving, the intelligent mobile vehicle 42 moves to reset, and the through plate 45 also moves with the arc block 5. When the welding head 3 welds the two sheets 41 to be welded, welding slag will be scattered on the surface of the protective rotating plate 48. This scheme arranges a through plate 45 on one side of the expansion roller 10 and the rotating roller 11. After the two sheets 41 to be welded move toward each other through the clamping device 33, they enter between the expansion roller 10 and the rotating roller 11. As the intelligent mobile vehicle 42 continues to move, the sheet 41 to be welded enters the through plate 45 at this time, and the ends of the sheet 41 to be welded squeeze the two protective rotating plates 48. The two protective rotating plates 48 are in contact with the surface of the sheet 41 to be welded under the action of the spring shaft 47, so as to protect the surfaces of the two sheets 41 to be welded and prevent welding slag from being scattered on the surfaces of the sheets 41 to be welded, thereby ensuring the beauty of the molded parts.
