Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, and particularly relates to a parallel track robot welding device. Background Technology

[0002] In modern industrial production, welding is a crucial metal joining process widely used in numerous fields such as automobile manufacturing, steel structure construction, shipbuilding, and pipeline engineering. With the continuous advancement of industrial automation, robotic welding technology, due to its advantages such as stable welding quality, high efficiency, and low labor intensity, has gradually replaced traditional manual welding methods.

[0003] In existing large workpiece welding operations, fixed welding robots or single-track mobile welding robots are mostly used for welding operations. However, existing track-mounted robot welding devices have several shortcomings in practical use: First, most track-mounted robots use a single-rail structure, resulting in poor stability when moving on the track, especially when performing long welds or multi-position welding. The robot body is prone to lateral swaying, affecting the positioning accuracy of the welding gun and the welding quality. Second, the positioning and clamping of the workpiece at the welding station is cumbersome, usually requiring manual handling to move the workpiece to the designated position before clamping and fixing it. This is inefficient, and the workpiece is prone to displacement due to heat deformation or external forces during welding, leading to welding misalignment and affecting welding quality. Third, welding slag and spatter generated during welding easily adhere to the track and worktable surface. If not cleaned in time, the welding slag will form hard particles after cooling and solidification, affecting the flatness of the track and the stability of subsequent workpiece placement, thereby reducing welding accuracy. Fourth, after welding, existing track-mounted robot welding devices require manual removal of the welded workpiece from the station. Due to the high temperature of the workpiece after welding and the possibility of local deformation, manual removal not only poses safety hazards but also has low efficiency. The aforementioned problems severely restrict the overall efficiency of automated welding production lines. Summary of the Invention

[0020] A parallel track robot welding device according to the present invention:

[0021] 1. This parallel track robotic welding device, by setting two parallel tracks, enables the robotic arm to slide stably on the tracks, effectively preventing lateral swaying of the robotic arm during welding and improving the positioning accuracy of the welding gun and the welding quality.

[0022] 2. This parallel track robotic welding device, through a conveying mechanism, transports the arc-shaped plate and the workpiece on it to the welding area. The workpiece contacts the transverse positioning frame and the longitudinal positioning frame, which can adjust the flatness and position of the workpiece to prevent misalignment during welding. When the arc-shaped plate moves to the welding area, the guide shaft slides in the guide groove, and the arc-shaped clamping box is pulled towards the workpiece through the connecting plate and the L-shaped pull plate, so that the arc-shaped clamping plate automatically clamps the workpiece, ensuring the stability of the welding process.

[0024] 4. In this parallel track robot welding device, when the conveyor belt moves the placed arc plate to its bottom, the conveyor rod drives the rotating rod to rotate through the belt, causing the reciprocating moving block to reciprocate along the reciprocating thread groove, which in turn drives the cleaning roller and brush to reciprocate and rotate, completing the surface cleaning work of the welding position of the track and worktable, effectively preventing welding slag residue on the device from affecting the flatness of the next workpiece placement, and improving the subsequent welding quality.

[0025] 5. In this parallel track robot welding device, the rotating rod drives the turntable plate to rotate, and through the push-pull rod and transmission seat, the piston moves back and forth in the cylinder, compressing the gas and expelling it from the jet hole. The ejected gas cools the welded workpiece, making it easier to remove the workpiece later. At the same time, it blows away the welding slag, further ensuring the cleanliness of the worktable.

[0046] like Figures 1 to 7 As shown, a parallel track robot welding device of the present invention includes a support frame 101, a welding support frame 102 fixedly connected to the side wall of the support frame 101, a fixed top plate 103 fixedly connected to the top of the welding support frame 102, a robotic arm 104 fixedly connected to the bottom of the fixed top plate 103, and a welding gun 105 fixedly connected to the side wall of the robotic arm 104. This arrangement is for the robotic arm 104 to drive the welding gun 105 to perform welding. The device also includes:

[0047] The conveying mechanism 2 includes a fixed frame 201 fixedly connected to the side wall of the support frame 101. A servo motor 202 is fixedly connected to the side wall of the fixed frame 201. The conveying mechanism 2 is provided with two conveying rods 203. The outer wall of the conveying rod 203 is rotatably connected to the through hole of the support frame 101. One of the conveying rods 203 is fixedly connected to the output end of the servo motor 202. A conveyor belt 204 is sleeved on the outer wall of the conveying rod 203. A conveying support plate 205 is fixedly connected to the outer side of the conveying support plate 205. An arc-shaped plate 206 is fixedly connected to the outer side of the conveying support plate 205. This arrangement is so that the servo motor 202 drives the conveying rod 203 to rotate, the conveying rod 203 drives the conveyor belt 204 to move, and the conveyor belt 204 drives the conveying support plate 205 and the arc-shaped plate 206 to move.

[0048] Two parallel tracks (not shown in the figure) are fixedly connected to the top of the support frame 101, and the bottom of the robotic arm 104 is slidably connected to the two tracks. By setting up two parallel tracks, the stability of the robotic arm 104 during movement is significantly improved, avoiding the lateral swaying problem that is easy to occur in a single track structure, and ensuring the positioning accuracy of the welding gun 105.

[0049] A clamping mechanism 3 is provided on the top of the arc-shaped plate 206. The clamping mechanism 3 includes a limiting groove 301 opened on the top of the arc-shaped plate 206. A slide rod 302 is fixedly connected to the inner wall of the limiting groove 301. A slider 303 is slidably connected to the outer wall of the slide rod 302. This arrangement is for the slider 303 to slide on the slide rod 302. An arc-shaped clamping box 304 is fixedly connected to the top of the slider 303. A return spring 305 is fixedly connected to the inner wall of the arc-shaped clamping box 304. An arc-shaped clamping plate 306 is fixedly connected to the end of the return spring 305 away from the arc-shaped clamping box 304. This arrangement is for the return spring 305 to make the force between the arc-shaped clamping plate 306 and the first welded part 401 uniform, which can effectively prevent the deformation of the first welded part 401 when it is limited and fixed, thus improving the product quality.

[0050] An L-shaped pull plate 31 is fixedly connected to the side wall of the arc-shaped clamping box 304. A connecting shaft 32 is fixedly connected to the side wall of the L-shaped pull plate 31. A connecting plate 33 is rotatably connected to the outer wall of the connecting shaft 32.

A guide groove 37 is provided on the side wall of the guide plate 36. The inner wall of the guide groove 37 is slidably connected to the outer wall of the guide shaft 34. This arrangement is because the guide shaft 34 slides in the guide groove 37 on the guide plate 36. When the guide shaft 34 moves from the inclined groove on the guide groove 37 to the straight groove that is far away from where the arc plate 206 is placed, the guide shaft 34 pulls the connecting plate 33 to move. The connecting plate 33 pulls the arc-shaped clamping box 304 to move through the L-shaped pull plate 31.

[0051] A transverse positioning frame 402 is fixedly connected to the side wall of the support frame 101, and a longitudinal positioning frame 403 is fixedly connected to the side wall of the transverse positioning frame 402. A first welding component 401 is placed on the top of the arc plate 206. This arrangement is to allow the first welding component 401 to contact the transverse positioning frame 402 and the longitudinal positioning frame 403, so that the flatness of the first welding component 401 can be adjusted and the first welding component 401 can be prevented from being misaligned during welding. A second welding component 404 is placed on the side wall of the first welding component 401.

[0052] like Figures 8 to 9As shown, a cleaning mechanism 5 is symmetrically arranged on the outer wall of the conveyor rod 203. The cleaning mechanism 5 includes a belt 501 sleeved on the outer wall of the conveyor rod 203. A rotating rod 502 is drivenly connected to the inner wall of the belt 501. The rotating rod 502 passes through the side wall of the support frame 101 and extends to the outside. This arrangement is for the conveyor rod 203 to drive the belt 501 to move, and the belt 501 to rotate the rotating rod 502. A reciprocating threaded groove 503 is opened on the outer wall of the rotating rod 502. A reciprocating moving block 504 is threadedly connected to the inner wall of the reciprocating threaded groove 503. A sliding hole 505 is opened on the top of the reciprocating moving block 504.

This arrangement is for the reciprocating moving block 504 to reciprocate along the reciprocating threaded groove 503. The reciprocating block 504 drives the connecting seat 507 and the rotating rod 508 to reciprocate via the lifting rod 506. A cleaning roller 509 is fixedly connected to the outer wall of the rotating rod 508, and a brush 510 is fixedly connected to the outer wall of the cleaning roller 509.

An arc-shaped toothed plate 53 is meshed with the side wall of the gear 52. The side wall of the arc-shaped toothed plate 53 is fixedly connected to the side wall of the support frame 101. This arrangement is because the gear 52 and the arc-shaped toothed plate 53 mesh, causing the rotating rod 508 to rotate during movement. The rotating rod 508 drives the cleaning roller 509 and the brush 510 to rotate.

[0053] like Figures 10 to 12 As shown, a flipping and placing mechanism 6 is provided on the side wall of the support frame 101. The flipping and placing mechanism 6 includes a support plate 601 fixedly connected to the side wall of the support frame 101. A cylinder 602 is fixedly connected to the top of the support plate 601.

A connecting rod 605 is rotatably connected to the end of the push-pull plate 604 away from the push seat 603. A fixed seat 606 is fixedly connected to the side wall of the support frame 101. A flipping plate 607 is rotatably connected to the outer wall of the fixed seat 606. One end of the connecting rod 605 passes through the side wall of the flipping plate 607 and extends to the outside. This arrangement is so that the cylinder 602 pushes the push seat 603 to rise, the push seat 603 pushes the push-pull plate 604 to move, and the push-pull plate 604 pushes the flipping plate 607 to flip around the fixed seat 606 as the axis through the connecting rod 605.

[0054] The flipping and placing mechanism 6 also includes a support circular plate 61 fixedly connected to the side wall of the flipping plate 607. A second cylinder 62 is fixedly connected to the top of the support circular plate 61. The output end of the second cylinder 62 passes through the top of the support circular plate 61 and extends to the outside. A lowering circular plate 63 is fixedly connected to the output end of the second cylinder 62. A hinge seat 64 is fixedly connected to the outer wall of the lowering circular plate 63. A clamping pull plate 65 is rotatably connected to the side wall of the hinge seat 64. A connecting shaft 66 is rotatably connected to the inner wall of the through hole of the clamping pull plate 65. A clamping plate 67 is rotatably connected to the outer wall of the connecting shaft 66. A shaft seat 68 is rotatably connected to the side wall of the clamping plate 67. The side wall of the shaft seat 68 is fixedly connected to the outer wall of the support circular plate 61. This arrangement is so that the second cylinder 62 pulls the lowering circular plate 63 to retract, the lowering circular plate 63 pulls the clamping pull plate 65 to move, and the clamping pull plate 65 drives the clamping plate 67 to clamp the second welded part 404.

[0055] like Figure 13 As shown, traditional welding methods involve using high temperatures to complete the welding process. After welding, manual intervention is required to remove the welded parts, which poses certain safety risks to the operators. Furthermore, the sparks generated during welding form weld slag after cooling. If this slag remains on the device and is not thoroughly removed, it will affect the flatness of subsequent workpiece installation. Reduced flatness may lead to a decrease in the quality of the final product. Therefore, traditional welding methods have limitations in terms of both safety and product quality. Air jet mechanisms 7 are symmetrically arranged at both ends of the right-side rotating rod 502. Each air jet mechanism 7 includes a turntable plate 701 fixedly connected to the end of the rotating rod 502. A push-pull rod 702 is rotatably connected to the outer wall of the turntable plate 701. A transmission seat 703 is rotatably connected to the end of the push-pull rod 702 away from the turntable plate 701. A movable... A cylinder 705 is slidably connected to the outer wall of the piston 704. The bottom of the cylinder 705 is fixedly connected to the top of the transverse positioning frame 402. An air jet rod 706 is connected to the outer wall of the cylinder 705. An air jet hole 707 is opened on the outer wall of the air jet rod 706. This is designed so that the rotating rod 502 drives the turntable plate 701 to rotate. The turntable plate 701 pushes and pulls the push-pull rod 702, so that the push-pull rod 702 drives the piston 704 to reciprocate through the transmission seat 703. The piston 704 moves inside the cylinder 705, so that the piston 704 compresses the gas inside the cylinder 705. The gas is transmitted to the air jet rod 706 and discharged from the air jet hole 707. The sprayed gas cools the welded workpiece, making it easier for the operator to remove the workpiece. At the same time, the sprayed gas can clean the welding slag formed after the sparks cool down, preventing the welding slag from affecting the flatness of the subsequent workpiece installation.

[0056] The working principle of a parallel track robot welding device: During use, the first welding part 401 needs to be placed on the arc-shaped plate 206. The servo motor 202 drives the conveyor rod 203 to rotate, which in turn drives the conveyor belt 204. When the conveyor belt 204 moves the conveyor support plate 205 and the arc-shaped plate 206 to the welding area, the first welding part 401 contacts the transverse positioning frame 402 and the longitudinal positioning frame 403, allowing for adjustment of the flatness of the first welding part 401 and preventing misalignment during welding. When the arc-shaped plate 206 moves to the welding area, the guide shaft 34 slides within the guide groove 37 on the guide plate 36. When the guide shaft 34 moves from the inclined groove on the guide groove 37 to a straight groove farther from the arc-shaped plate 206, the guide shaft 34 pulls... The connecting plate 33 moves, and the connecting plate 33 pulls the arc-shaped clamping box 304 to move via the L-shaped pull plate 31. The arc-shaped clamping box 304 moves toward the first welded part 401, thereby causing the arc-shaped clamping plate 306 to clamp the first welded part 401, thus ensuring the stability of the welding process, improving the uniformity of the welding surface and the welding accuracy. There is no need for manual positioning and fixing of the first welded part 401, which greatly simplifies the operation process and makes the entire welding process more convenient and efficient. By reducing the reliance on manual operation, it not only reduces the labor intensity of the workers, but also significantly improves the efficiency and quality of the welding operation. The return spring 305 makes the force between the arc-shaped clamping plate 306 and the first welded part 401 uniform, which can effectively prevent the deformation of the first welded part 401 when it is limited and fixed, thus improving the product quality.

[0057] The second weldment 404 is placed on the clamping plate 67. Cylinder 2 62 pulls the downward pressing plate 63 to retract, and the downward pressing plate 63 pulls the clamping pull plate 65 to move. The clamping pull plate 65 drives the clamping plate 67 to clamp the second weldment 404. When the first weldment 401 moves to the welding area, cylinder 1 602 pushes the push seat 603 to rise. The push seat 603 pushes the push-pull plate 604 to move. The push-pull plate 604, through the connecting rod 605, pushes the flipping plate 607 to flip around the fixed seat 606, causing the clamping plate... The second welding part 404 on 67 is attached to the first welding part 401. The robotic arm 104 slides along two parallel tracks to the welding position. Then, the robotic arm 104 drives the welding gun 105 to weld the second welding part 404 and the first welding part 401. After welding, the arc plate 206 is placed away from the welding area, so that the clamping mechanism 3 automatically releases the clamp on the first welding part 401, so that the welded workpiece is automatically removed without manual handling. This automated operation is repeated, which can significantly improve the efficiency of welding operations.

[0058] When the conveyor belt 204 moves the arc-shaped plate 206 to its bottom, the conveyor rod 203 drives the belt 501 to move. The belt 501 causes the rotating rod 502 to rotate, thereby causing the reciprocating moving block 504 to reciprocate along the reciprocating threaded groove 503. The reciprocating moving block 504 drives the connecting seat 507 and the rotating rod 508 to reciprocate through the lifting rod 506, causing the rotating rod 508 to move along the arc-shaped limiting groove plate 51. Because the gear 52 meshes with the arc-shaped toothed plate 53, the rotating rod 508 rotates during the movement. The rotating rod 508 drives the cleaning roller 509 and the brush 510 to rotate, completing the surface cleaning work of the track and welding position, preventing welding slag. The residue remaining on the device affects the placement of the first welded part 401 in the next operation, thus improving the subsequent welding quality. The rotating rod 502 drives the turntable plate 701 to rotate. The turntable plate 701 pushes and pulls the push-pull rod 702, causing the push-pull rod 702 to drive the piston 704 to reciprocate through the transmission seat 703. The piston 704 moves inside the cylinder 705, compressing the gas inside the cylinder 705. The gas is transmitted to the jet rod 706 and discharged from the jet hole 707. The sprayed gas cools the welded workpiece, making it easier for the workers to remove the workpiece. At the same time, the sprayed gas can clean the welding slag formed after the sparks cool down, preventing the welding slag from affecting the flatness of the subsequent workpiece installation.
