Description

An industrial robot-assisted welding device Technical Field

[0001] This invention is an industrial robot-assisted welding device, belonging to the technical field of industrial robot welding auxiliary equipment. Background Technology

[0002] During the welding process of industrial robots, the nozzle of the welding torch can become clogged with spatter, impurities, and residual welding wire. If not cleaned for a long time, these impurities will block the gas shielding sleeve, preventing the shielding gas from covering the weld pool smoothly. This causes air intrusion, leading to weld oxidation or porosity, which affects the weld formation quality and welding strength. Ultimately, this will affect the continuity and quality stability of the industrial robot's welding operation, hindering the industrial use of industrial robots.

[0003] Therefore, an industrial robot-assisted welding device is proposed that can clear blockages from the nozzle of an industrial robot welding torch and guide and collect the cleared slag. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an industrial robot-assisted welding device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an industrial robot-assisted welding device, comprising a support column, a control box at the top of the support column, a protective frame II and a waste bin respectively installed on one side of the front of the control box and the support column, a through hole adapted to the industrial robot welding torch at the top center of the protective frame II, a clamping assembly adapted to the industrial robot welding torch installed on the top of the protective frame II, a torch cleaning mechanism adapted to the industrial robot welding torch installed inside the control box and inside the protective frame II, a cylindrical cover sleeved on the outside of the torch cleaning mechanism, the cylindrical cover fixed to the inner wall of the protective frame II, a fixing plate installed on one side of the clamping assembly, and a wire cutting mechanism and an oil spray box installed on the fixing plate.

[0006] Furthermore, the clamping assembly includes a fixed frame fixed to the top side of the control box, and a push cylinder and a clamping block are respectively installed on both sides of the fixed frame. The rubber blocks at the output ends of the clamping block and the push cylinder are both adapted to the welding torch of the industrial robot.

[0007] Furthermore, the gun cleaning mechanism includes a fixing member and a gun cleaning assembly. The fixing member is mounted on the control box, and the clamping end of the fixing member extends to the outside of the control box. The gun cleaning assembly is mounted inside the clamping end.

[0008] Furthermore, the fixing component includes a fixing seat and a clamping seat. The fixing seat is fixed inside the control box, and the connecting end of the fixing seat extends to the outside of the control box. The two clamping seats are fixed to the connecting end of the fixing seat by bolts, and the gun cleaning assembly is clamped and fixed between the two clamping seats.

[0009] Furthermore, the cleaning gun assembly includes a top cylinder, a middle cylinder, and a bottom cylinder. The top cylinder and the bottom cylinder are located at the upper and lower ends of the middle cylinder, respectively. A motor is installed inside the top cylinder, and a reamer is installed at the output end of the motor. A connecting ring is installed on the outer surface of the reamer by screws. A cleaning component is provided on the outer circumference of the connecting ring. A guide cylinder is installed at the bottom of the top cylinder, and a limit ring is fixed at the bottom of the guide cylinder. The limit ring is slidably connected to the middle cylinder. An installation slot is opened at the top opening of the middle cylinder, and a fixing ring is installed in the installation slot by screws. The guide cylinder is slidably connected to the fixing ring. An electric push rod is provided in the inner middle of the middle cylinder. The electric push rod is installed in the bottom cylinder and is located inside the guide cylinder and the limit ring. The top telescopic end of the electric push rod is connected and fixed to the bottom of the top cylinder.

[0010] Furthermore, a protective shell is fixedly installed at the bottom of the top cylinder and on the outside of the guide cylinder, and a receiving groove is provided on the top outer side of the middle cylinder, the receiving groove being adapted to the protective shell.

[0011] Furthermore, the cleaning component includes a mounting block integrally connected to the outer surface of the connecting ring. The end of the mounting block is movably connected to the rotating block via a shaft. The mounting block and the rotating block each have a mating groove and a mating part on opposite sides. The outer surfaces of both sides of the mounting block each have a stop block that mates with the mating part. The rotating block has a movable groove in the middle of the end away from the mounting block. A movable block is rotatably connected in the movable groove. A fixed block is fixed to the end of the movable block. A movable column is rotatably connected to the bottom of the fixed block. The outer surface of the movable column has several cleaning strips. The bottom of the movable column has a counterweight column. The outer surface of the counterweight column has several counterweight blocks.

[0012] Furthermore, a long screw is installed at the bottom of the counterweight, and the long screw passes through the counterweight and the movable column and is screwed to the bottom of the fixed block for fixation.

[0013] Furthermore, the wire-cutting mechanism includes a protective frame fixed to the fixed plate. A push cylinder and a side plate are fixed inside one side of the protective frame. A support rod is provided inside the other side of the protective frame. A U-shaped movable plate is movably connected to the support rod. A U-shaped groove is provided at the bottom of the U-shaped movable plate. A T-shaped push rod is connected to the output end of the push cylinder. The T-shaped push rod is engaged in the U-shaped groove. A movable cutter and a fixed cutter are respectively provided on opposite sides of the top of the U-shaped movable plate and the side plate. A baffle is fixed to the outer surface of the push cylinder. A triangular baffle is fixed to the middle of the baffle. Both the triangular baffle and the baffle have through holes adapted to the output end of the push cylinder.

[0014] Furthermore, the fuel injection tank includes a housing, with an inlet and outlet at the top center of the housing, a nozzle at the bottom of the housing, the bottom of the nozzle being connected to an inlet pipe, the inlet pipe being connected to a reservoir, the bottom of the housing being a sloping structure, and an outlet pipe being installed at the sloping end of the housing, the outlet pipe being connected to a waste liquid tank.

[0015] The beneficial effects of the present invention are as follows: Through the design of the clamping component, after long-term use, the welding torch nozzle of the welding robot will be blocked by waste. At this time, the welding torch nozzle of the welding robot needs to be cleaned of waste residue. The welding robot inserts the welding torch nozzle into the fixed frame, and the control terminal starts the first push cylinder. The first push cylinder pushes the rubber block to move, and the welding torch is clamped and fixed by the rubber block and the clamping block.

[0016] Through the design of the cleaning mechanism, after prolonged use, the welding robot's welding torch is clamped and fixed by the clamping assembly. Then, the electric push rod and motor are activated. The motor drives the reamer to rotate, thus cleaning the slag from the welding torch nozzle. At the same time, the electric push rod is also activated, pushing the top cylinder to lift the motor and reamer, thereby cleaning the welding robot's welding torch nozzle. Because the cleaning assembly is enclosed within a cylindrical shell, the slag generated during the entire cleaning process is contained by the cylindrical shell and will not spread. Instead, it will fall steadily along the inner wall of the cylindrical shell into the waste bin below for collection. This effectively cleans the slag from the welding torch nozzle of the industrial robot, extending the service life of the welding torch.

[0017] By designing the cleaning components, while the motor drives the reamer to rotate and clean the slag, the cleaning components are set to rotate synchronously with the reamer to avoid slag accumulation on the top of the cylinder and to reduce manual cleaning time. In the initial stage of rotation, due to the slow speed, the cleaning components rotate along the outer wall of the top cylinder to clean the outer wall. As the speed increases, the rotating block rotates laterally at the end of the mounting block, and the movable block rotates outward on the rotating block. At the same time, the movable column and the counterweight column rotate circumferentially on the support frame composed of the fixed block and the long screw. When the movable column rotates, it will drive several movable columns to rotate and unfold to form a cleaning surface. Finally, several cleaning surfaces are formed as the reamer rotates, achieving the blocking and cleaning of the area around the top cylinder. This causes the slag to be thrown onto the inner wall of the cylindrical cover and then descends along the cylindrical cover into the waste bin.

[0018] Through the design of the wire-cutting mechanism, after the welding robot has cleaned the slag from the welding torch nozzle, the welding robot inserts the welding torch into the protective frame. The welding wire from the welding torch is continuously output between the moving cutter and the fixed cutter. At this time, the control terminal starts the second push cylinder, which extends the piston rod. The piston rod pushes the U-shaped movable plate to rotate through the T-shaped push rod. The U-shaped movable plate drives the moving cutter to approach the fixed cutter to achieve the cutting action of the welding wire.

[0019] The design of the spray tank allows the welding robot to insert the welding torch into the housing through the inlet and outlet. Then, the control terminal starts the oil pump in the reservoir, which sprays the liquid in the reservoir onto the outer surface of the welding torch through the nozzle to achieve the curing effect of the torch.

[0020] The space between the top and middle cylinders is shielded by a protective shell to prevent slag generated during the cleaning process from causing interference and erosion. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A control box 2 is provided on the top of the support column 1. A protective frame 46 and a waste bin 47 are respectively installed on one side of the front of the control box 2 and the support column 1. A through hole adapted to the welding torch of the industrial robot is opened at the center of the top of the protective frame 46. A clamping assembly adapted to the welding torch of the industrial robot is installed on the top of the protective frame 46. A torch cleaning mechanism adapted to the welding torch of the industrial robot is installed inside the control box 2 and inside the protective frame 46. A cylindrical cover 36 is sleeved on the outside of the torch cleaning mechanism. The cylindrical cover 36 is fixed on the inner wall of the protective frame 46. A fixing plate is installed on one side of the clamping assembly. A wire cutting mechanism and an oil spray box 45 are installed on the fixing plate.

[0026] Referring to Figure 1, the clamping assembly includes a fixed frame 3 fixed to the top side of the control box 2. A push cylinder 4 and a clamping block 5 are respectively installed on both sides of the fixed frame 3. The rubber blocks at the output ends of the clamping block 5 and the push cylinder 4 are adapted to the welding torch of the industrial robot. After long-term use, the welding torch nozzle of the welding robot will be blocked by waste. At this time, the welding torch nozzle of the welding robot needs to be cleaned of waste residue. The welding robot inserts the welding torch nozzle into the fixed frame 3, and the control terminal starts the push cylinder 4. The push cylinder 4 pushes the rubber block to move, and the welding torch is clamped and fixed by the rubber block and the clamping block 5.

[0027] Referring to Figures 5-7, the gun cleaning mechanism includes a fixing member 6 and a gun cleaning assembly 7. The fixing member 6 is mounted on the control box 2, and its clamping end extends to the outside of the control box 2. The gun cleaning assembly 7 is mounted inside the clamping end. The fixing member 6 includes a fixing seat 8 and a clamping seat 9. The fixing seat 8 is fixed inside the control box 2, and its connecting end extends to the outside of the control box 2. Two clamping seats 9 are fixed to the connecting end of the fixing seat 8 by bolts. The gun cleaning assembly 7 is clamped and fixed between the two clamping seats 9. The design provides stable support for the gun cleaning assembly 7 while also facilitating quick disassembly. The gun cleaning assembly 7 includes a top cylinder 10, a middle cylinder 11, and a bottom cylinder 12. The top cylinder 10 and the bottom cylinder 12 are located at the upper and lower ends of the middle cylinder 11, respectively. A motor is installed inside the top cylinder 10, and a reamer 13 is installed at the output end of the motor. A connecting ring 21 is screwed onto the outer surface of the reamer 13. A cleaning element 22 is provided on the outer circumference of the connecting ring 21. A guide cylinder 14 is installed at the bottom of the top cylinder 10. A limiting ring 15 is fixed to the bottom of the guide cylinder 14. The limiting ring 15 is slidably connected inside the middle cylinder 11. An installation slot 17 is provided at the top opening of the middle cylinder 11. A fixing ring 18 is installed in the installation slot 17 by screws. The guide cylinder 14 is slidably connected inside the fixing ring 18. An electric push rod 19 is provided in the middle of the middle cylinder 11. The electric push rod 19 is installed inside the bottom cylinder 12. The electric push rod 19 is located inside the guide cylinder 14 and the limiting ring 15. The top telescopic end of the electric push rod 19 is connected to the bottom of the top cylinder 10. After prolonged use, the welding torch of the welding robot is clamped and fixed by the clamping assembly. Then, the electric push rod 19 and the motor are activated. The motor drives the reamer 13 to rotate, thus cleaning the slag at the welding torch nozzle. At the same time, the electric push rod 19 is also activated, pushing the top cylinder 10 to drive the motor and the reamer 13 to rise, thus cleaning the welding torch nozzle of the welding robot. Because the torch cleaning assembly 7 is enclosed inside the cylindrical cover 36, the slag generated during the entire cleaning process is restricted by the cylindrical cover 36 and will not spread. Instead, it will fall steadily along the inner wall of the cylindrical cover 36 into the waste bin 47 below for collection.

[0028] Referring to Figure 7, a protective shell 16 is fixedly installed at the bottom of the top cylinder 10 and outside the guide cylinder 14. A receiving groove 20 is provided on the top outer side of the middle cylinder 11, and the receiving groove 20 is adapted to the protective shell 16. Through the design of the protective shell 16 and the receiving groove 20, when the electric push rod 19 pushes the top cylinder 10 up for cleaning, the protective shell 16 blocks the space between the top cylinder 10 and the middle cylinder 11, avoiding interference and erosion caused by the slag generated during the cleaning process.

[0029] Referring to Figure 8, the cleaning component 22 includes a mounting block 23, which is integrally connected to the outer surface of the connecting ring 21. The end of the mounting block 23 is movably connected to the rotating block 24 via a shaft. A mating groove 25 and a mating piece 26 are respectively provided on opposite sides of the mounting block 23 and the rotating block 24. A stop block 27 that mates with the mating piece 26 is provided on each of the two outer surfaces of the mounting block 23. A movable groove 28 is provided in the middle of the end of the rotating block 24 away from the mounting block 23. A movable block 29 is rotatably connected within the movable groove 28. A fixing block 30 is fixed to the end of the movable block 29. A movable column 31 is rotatably connected to the bottom of the fixing block 30. Several cleaning strips 32 are provided on the outer surface of the movable column 31. A counterweight column 33 is provided at the bottom of the movable column 31. Several counterweight blocks 34 are provided on the outer surface of the counterweight column 33. A long screw 35 is installed at the bottom of the counterweight block 34, passing through the counterweight block 34 and the movable block 24. The column 31 is screwed to the bottom of the fixed block 30. While the motor drives the reamer 13 to rotate and clean the slag, in order to avoid the accumulation of slag on the top of the top cylinder 10 and to reduce the time for manual cleaning, the cleaning component 22 can rotate synchronously with the reamer 13. In the early stage of rotation, because the speed is slow, the cleaning component 22 will rotate along the outer wall of the top cylinder 10 to clean the outer wall. As the speed increases, the rotating block 24 will rotate laterally at the end of the mounting block 23, and the movable block 29 will rotate outward on the rotating block 24. At the same time, the movable column 31 and the counterweight column 33 will rotate circumferentially on the support frame composed of the fixed block 30 and the long screw 35. When the movable column 31 rotates, it will drive several movable columns 31 to rotate and unfold to form a cleaning surface. Finally, several cleaning surfaces are formed as the reamer 13 rotates, which can achieve the blocking and cleaning of the area around the top cylinder 10, so that the slag will be thrown onto the inner wall of the cylindrical cover 36 and then fall into the waste box 47 along the cylindrical cover 36.

[0030] Referring to Figures 1-3, the wire cutting mechanism includes a protective frame 42 fixed to the fixed plate. A push cylinder 39 and a side plate 40 are fixed to one side of the interior of the protective frame 42. A support rod is provided on the other side of the interior of the protective frame 42, and a U-shaped movable plate 41 is movably connected to the support rod. The bottom of the U-shaped movable plate 41 has a U-shaped groove. A T-shaped push rod is connected to the output end of the push cylinder 39, and the T-shaped push rod is engaged in the U-shaped groove. A movable cutter 43 and a fixed cutter 44 are respectively provided on opposite sides of the top of the U-shaped movable plate 41 and the side plate 40. A stop is fixed to the outer surface of the push cylinder 39. Plate 37, with a triangular shielding frame 38 fixed in the middle. Both the triangular shielding frame 38 and the plate 37 have through holes adapted to the output end of the push cylinder 39. After the welding robot cleans the slag from the welding torch, the welding robot inserts the welding torch into the protective frame 42. The welding wire from the welding torch is continuously output between the moving cutter 43 and the fixed cutter 44. At this time, the control terminal starts the push cylinder 39. The push cylinder 39 extends the piston rod, and the piston rod pushes the U-shaped movable plate 41 to rotate through the T-shaped push rod. The U-shaped movable plate 41 drives the moving cutter 43 to move closer to the fixed cutter 44 to achieve the shearing action of the welding wire.

[0031] The oil spray tank 45 includes a housing with an inlet and outlet at the top center and a nozzle at the bottom of the housing. The bottom of the nozzle is connected to an oil inlet pipe, which is connected to a liquid storage tank. The bottom of the housing has a sloping structure, and an oil outlet pipe is installed at the sloping end of the housing, which is connected to a waste liquid tank. In use, the welding robot inserts the welding torch into the housing through the inlet and outlet. Then, the control terminal starts the oil pump in the liquid storage tank, which sprays the liquid in the storage tank onto the outer surface of the welding torch through the nozzle to achieve the curing effect of the torch.

[0032] After prolonged use, the welding torch nozzle of the welding robot becomes clogged with waste material. At this point, the welding torch nozzle needs to be cleaned. The welding robot inserts the welding torch nozzle into the fixing frame 3. The control terminal activates the push cylinder 4, which moves the rubber block. The rubber block and the clamping block 5 clamp and fix the welding torch. Subsequently, the electric push rod 19 and the motor are activated. The motor drives the reamer 13 to rotate, thus cleaning the waste material from the welding torch nozzle. Simultaneously, the electric push rod 19 also activates, pushing the top cylinder 10 to lift the motor and reamer 13, thus cleaning the welding torch nozzle. This is because the torch cleaning assembly 7 is enclosed within the cylindrical cover 36. Therefore, the slag generated during the entire cleaning process is confined by the cylindrical cover 36 and will not spread. Instead, it will fall steadily along the inner wall of the cylindrical cover 36 into the waste bin 47 below for collection. This allows for the cleaning of slag inside the welding torch nozzle of the industrial robot, improving the service life of the welding torch. While the reamer 13 is cleaning, and the motor drives the reamer 13 to rotate and clean the slag, to avoid slag accumulation on the top of the top cylinder 10 and to reduce manual cleaning time, the cleaning component 22 can rotate synchronously with the reamer 13. In the initial stage of rotation, because the speed is relatively slow, the cleaning component 22 will fall along the top cylinder. The outer wall rotation of the reamer 10 enables the cleaning of the outer wall. As the rotation speed increases, the rotating block 24 rotates laterally at the end of the mounting block 23, and the movable block 29 rotates outward on the rotating block 24. At the same time, the movable column 31 and the counterweight column 33 rotate circumferentially on the support frame composed of the fixed block 30 and the long screw 35. When the movable column 31 rotates, it drives several movable columns 31 to rotate and unfold to form a cleaning surface. Finally, several cleaning surfaces are formed as the reamer 13 rotates, achieving the shielding and cleaning of the area around the top cylinder 10, so that the slag is thrown onto the inner wall of the cylindrical cover 36 and then falls down along the cylindrical cover 36 into the waste bin 47. After the slag removal is completed, the welding robot inserts the welding torch into the protective frame 42. The welding wire from the torch is continuously output between the moving cutter 43 and the fixed cutter 44. At this time, the control terminal activates the push cylinder 39, which extends the piston rod. The piston rod pushes the U-shaped movable plate 41 to rotate through the T-shaped push rod. The U-shaped movable plate 41 drives the moving cutter 43 to move closer to the fixed cutter 44 to achieve the shearing action of the welding wire. After the welding wire is sheared, the welding robot can insert the welding torch into the housing through the inlet and outlet. Then, the control terminal activates the oil pump in the liquid storage tank. The oil pump sprays the liquid in the liquid storage tank onto the outer surface of the welding torch through the nozzle to achieve the curing effect of the torch.
