Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Refer to Figure 1-8, a mechatronic automatic welding device, including a bottom plate 1 and a filter box 27. On the upper surface of the bottom plate 1, an automatic robotic arm 2 is installed. At the output end of the automatic robotic arm 2, a welding device 3 is installed. On the upper surface of the bottom plate 1, two sliding grooves 4 are opened. Inside the sliding grooves 4, sliding blocks 5 are installed. One side of the sliding block 5 is connected to one side inside the sliding groove 4 through a first spring 14. At the upper end of the sliding block 5, an L-shaped clamping plate 6 is installed. On the upper surface of the L-shaped clamping plate 6, a groove 7 is provided. Inside the groove 7, a protective plate 8 is slidably installed. The axial section height of the protective plate 8 is higher than the axial section height of the groove 7, so that the upper part of the protective plate 8 protrudes from the groove 7 and its height is guaranteed, avoiding the harm caused by sputtered welding slag and the like to the staff during the welding process, and facilitating the effective protection of the staff.

[0031] On one side of the protective plate 8, a resisting rod 15 is installed. On the upper surface of the bottom plate 1, a supporting structure is installed. The supporting structure includes a first telescopic rod 16 fixedly installed on the left side of the upper surface of the bottom plate 1. At the upper end of the first telescopic rod 16, a top plate 17 is fixedly installed. The top plate 17 and the resisting rod 15 cooperate with each other. At the lower surface of the top plate 17, a supporting rod 18 is hinged. The supporting structure also includes a connecting block 19 fixedly installed on the left side of the L-shaped clamping plate 6. One end of the supporting rod 18 away from the top plate 17 is connected to the upper surface of the connecting block 19 through a hinge. When the two L-shaped clamping plates 6 approach each other, they can drive the two connecting blocks 19 to approach each other, thereby driving the supporting rod 18 to rotate. The supporting rod 18 jacks up the top plate 17, so that the top plate 17 resists and drives the resisting rod 15 to move upward. The resisting rod 15 can drive the protective plate 8 to move upward, thereby blocking the front and back sides of the item to be welded with the protective plate 8. This can not only prevent sputtering, but also facilitate the staff to directly observe the welding process through the protective plate 8, facilitating the staff to debug the equipment and monitor the welding work, and effectively protecting the life and health of the staff.

[0032] On the outside of the L-shaped clamping plate 6, an L-shaped fixing rod 9 is installed. On the upper surface of the bottom plate 1, two swing plates 10 are hinged. On the outside of the swing plates 10, movable blocks 11 are installed. The L-shaped fixing rod 9 movably penetrates through the movable blocks 11. On the outside of the bottom plate 1, a push rod 12 is installed. At the output end of the push rod 12, a U-shaped fixing plate 13 is installed. The inner side of the U-shaped fixing plate 13 abuts against the swing plates 10, facilitating the swing plates 10 to rotate in the direction of approaching each other, and effectively improving the rotation sensitivity of the swing plates 10.

[0033] On the upper surface of the bottom plate 1, an air suction fan 23 is installed. At the air inlet of the air suction fan 23, an air suction nozzle 22 is connected through a connecting pipe 21. The connecting pipe 21 is clamped on one side of the automatic robotic arm 2 through a fixing buckle 20. The air suction nozzle 22 is fixedly connected to one end of the connecting pipe 21 close to the welding device 3. The air suction nozzle 22 is made of steel, so that the air suction nozzle 22 is heat-resistant and its service life is improved.

[0034] A water tank 25 is installed on the upper surface of the base plate 1, and the suction fan 23 is connected to the water tank 25 through the first air duct 24. The water level inside the water tank 25 is higher than the top of the first air duct 24, and the water level inside the water tank 25 is lower than the bottom of the second air duct 26, which is convenient for passing smoke into the water. After the smoke passes through the water, some dust and impurities inside are directly precipitated, and some water-soluble substances inside are directly dissolved in water, which effectively increases the effect of precipitation and filtration, and is convenient for improving the effect of environmental protection.

[0035] A filter box 27 is connected to one side of the water tank 25 through a second air duct 26. A positioning tube 28 is fixedly connected to the rear side of the filter box 27. The positioning tube 28 is sleeved on the outside of the second air duct 26. The filter box 27 is filled with an adsorption material 30. An air outlet pipe 31 is connected to the front side of the filter box 27. Baffle rods 32 are fixedly installed on both sides of the filter box 27 to facilitate the adsorption of harmful substances in the smoke, making the exhaust gas more environmentally friendly. A sealing gasket 29 is fixedly installed inside the positioning tube 28. The sealing gasket 29 is made of rubber material to prevent smoke from escaping from the gap between the second air duct 26 and the positioning tube 28 to pollute the environment.

[0036] A resistance structure is movably installed on one side of the water tank 25, and the resistance structure includes a threaded rod 39 movably installed on the lower part of the front face of the water tank 25. The resistance structure also includes a second telescopic rod 37 fixedly installed on the left and right sides of the front face of the water tank 25. A moving plate 38 is fixedly installed on one end of the front face of the two second telescopic rods 37. The threaded rod 39 threads through the moving plate 38. The resistance structure also includes an L-shaped rotating plate 33 hinged on one side of the front face of the water tank 25. A first through groove 34 is provided on the top of the L-shaped rotating plate 33, and a second through groove 35 is provided on the bottom of the L-shaped rotating plate 33, so that the filter box 27 and the threaded rod 39 will not affect the normal rotation of the L-shaped rotating plate 33, thereby facilitating the effective and normal use of the L-shaped rotating plate 33.

[0037] A second spring 36 is fixedly connected to the rear side of the L-shaped rotating plate 33, and one end of the second spring 36 away from the L-shaped rotating plate 33 is fixedly connected to the front side of the water tank 25. The movable plate 38 is in conflict with the L-shaped rotating plate 33. When replacement is needed, the movable plate 38 is driven to move toward the water tank 25 by rotating the threaded rod 39. Thereafter, the L-shaped rotating plate 33 rotates under the action of the second spring 36, so that the L-shaped rotating plate 33 no longer conflicts with the blocking rod 32. At this time, the filter box 27 can be directly taken out and removed, which is convenient for operations such as replacing the adsorption material 30, effectively reducing the labor intensity of the work and improving the work efficiency.

[0038] Working principle: When the present invention is working, the object to be welded is placed between the two L-shaped clamping plates 6. First, by turning on the switch of the push rod 12, the U-shaped fixing plate 13 is driven to move upward. Since the inner side of the U-shaped fixing plate 13 is in contact with the swing plate 10, the U-shaped fixing plate 13 is convenient for the two swing plates 10 to rotate in a direction close to each other, thereby driving the movable block 11 to move, and the movable block 11 is made to slide on the outside of the L-shaped fixing rod 9. While the two swing plates 10 are rotating, since the lower end of the L-shaped clamping plate 6 is installed on the slider 5, and the slider 5 can slide inside the slide groove 4, and by providing a first spring 14, the two L-shaped clamping plates 6 can be stably moved in a direction close to each other, thereby clamping the object to be welded. The push rod 12 automatically performs the clamping work, eliminating the need for manual tool clamping operations, reducing the labor intensity, and effectively improving the working efficiency of the equipment. During the clamping process, the two L-shaped clamping plates 6 approach each other to drive the two connecting blocks 19 to approach each other, thereby driving the support rod 18 to rotate, and the support rod 18 lifts the top plate 17, so that the top plate 17 contacts and drives the contact rod 15 to move upward, and the contact rod 15 can drive the protective plate 8 to move upward, so that the front and rear sides of the object to be welded are blocked by the protective plate 8, which can not only prevent spattering, but also facilitate the staff to directly observe the welding process through the protective plate 8, which is convenient for the staff to debug the equipment and monitor the welding work, and effectively protects the workers. The life and health of the workers are protected. By turning on the switch of the suction fan 23, the smoke generated by welding can be sucked into the connecting pipe 21 through the suction nozzle 22. Since the suction nozzle 22 is fixedly connected to the end of the connecting pipe 21 close to the welding equipment 3, and the suction nozzle 22 is made of steel, the suction nozzle 22 is resistant to high temperature, which increases its service life. The smoke is sent to the inside of the water tank 25 through the connecting pipe 21, the suction fan 23, and the first air duct 24. Since the water level inside the water tank 25 is higher than the top of the first air duct 24, and the water level inside the water tank 25 is lower than the bottom of the second air duct 26, after the smoke passes through the water, some dust and impurities inside it are directly precipitated, and some water-soluble substances inside it are directly dissolved in water. Then the remaining gas is transmitted to the adsorption material 30 through the second air duct 26. The adsorption work is carried out, and the gas after subsequent treatment is discharged through the air outlet pipe 31. A sealing gasket 29 is fixedly installed inside the positioning tube 28. The sealing gasket 29 is made of rubber material to prevent smoke from escaping from the gap between the second air duct 26 and the positioning tube 28 to pollute the environment. After long-term use, the adsorption material 30 inside the filter box 27 may fail. When it needs to be replaced, the moving plate 38 is driven to move toward the water tank 25 by rotating the threaded rod 39. Since the first through groove 34 is provided on the top of the L-shaped rotating plate 33 and the second through groove 35 is provided on the bottom of the L-shaped rotating plate 33, the filter box 27 and the threaded rod 39 will not affect the normal rotation of the L-shaped rotating plate 33. Therefore, the L-shaped rotating plate 33 rotates under the action of the second spring 36.The L-shaped rotating plate 33 is no longer in contact with the blocking rod 32. At this time, the filter box 27 can be directly taken out and disassembled, which is convenient for operations such as replacing the adsorption material 30.,

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
