Description

Technical Field

[0001] The present invention belongs to the technical field related to welding equipment, and more specifically, particularly relates to an intelligent welding equipment for fuel filter processing. Background Art

[0002] An automotive fuel filter is a device used to filter impurities and contaminants in automotive fuel. When processing a fuel filter, in order to improve processing efficiency and precision, a laser welding equipment is usually required to process the automotive fuel filter. Laser welding uses a high-energy laser pulse to locally heat a small area of the material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for welding thin-walled materials and precision parts, and can achieve spot welding, butt welding, lap welding, seal welding, etc. It has a high depth-to-width ratio, a small weld width, a small heat-affected zone, small deformation, a fast welding speed, a flat and beautiful weld, and requires no treatment or only simple treatment after welding. The weld quality is high, there are no pores, it can be precisely controlled, the focused light spot is small, the positioning accuracy is high, and it is easy to achieve automation. However, the welding equipment in the prior art has the following defects: In the prior art, when an intelligent welding equipment welds and processes a fuel filter, arc discharge will occur, so a protective cover needs to be installed on the laser welding machine; and when the laser welding machine is welding, waste gas will be generated, and the connection between the existing protective cover and the base is not tight, resulting in a gap between the protective cover and the base, and then the waste gas leaks from the protective cover, polluting the environment.

[0003] In the prior art, the absorption port position of the air extraction component in the intelligent welding equipment is usually fixed, and the absorption port position of the air extraction component cannot be adjusted, resulting in difficulty in quickly absorbing the waste gas in the protective cover; and there is a large amount of waste gas generated at the laser welding interface, which cannot be completely sucked away by the air extraction component, resulting in poor absorption efficiency of harmful waste gas.

[0004] In the prior art, in order to improve the welding and processing effect of the fuel filter, an intelligent welding equipment usually fills a protective gas in the protective cover and uses the protective gas to improve the welding and processing effect of the fuel filter; however, the protective gas usually uses two gases mixed and then ejected. Due to the relatively simple structure of the existing air extraction component, it is difficult to absorb waste gas while treating the protective gas, thus affecting the rapid ejection of the protective gas.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an intelligent welding equipment for fuel filter processing is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0016] Further technical solution: A workbench is arranged on the upper side of the operating table. An operation panel is arranged on one side of the operating table.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The intelligent welding equipment for fuel filter processing of the present invention is provided with a protective cover, a movable ring, an annular part, and a compression spring. The annular part is supported by the upper side of the workbench, and the protective cover continues to move downward, so that the movable ring slides in the protective cover. The sliding of the movable ring compresses a number of compression springs to generate elastic force, and the elastic force generated by the compression springs acts on the movable ring and the annular part, so that the annular part is pressed on the upper side of the workbench, so that the protective cover, the movable ring, the annular part, and the workbench are used to protect the surroundings of the laser welding machine, reduce the exhaust gas generated by the laser welding machine from overflowing into the air, and prevent air pollution. Then, through the provision of the movable plate, the air frame, and the first one-way valve, the movable plate moves downward, so that the first air cavity generates negative pressure, and the exhaust gas generated by the laser welding machine is absorbed into the air frame by using a number of first one-way valves, and the exhaust gas in the air frame moves into the first air cavity. The movable plate moves downward, driving the several air frames to move downward, so that the several first one-way valves gradually approach the welding point of the laser welding machine, thereby achieving a close-range absorption of the exhaust gas, which is conducive to the rapid absorption of a large amount of exhaust gas generated by the welding point of the laser welding machine. Finally, the movable plate rotates to drive the several air frames to rotate, and the rotation of the several air frames drives the several first one-way valves, so that the several first one-way valves rotate around the laser welding machine. By using the continuous change of the vertical and circumferential positions of the several first one-way valves, the exhaust gas in the protective cover can be quickly absorbed into the first air cavity, avoiding the exhaust gas from overflowing from the protective cover and preventing air pollution.

[0018] The invention discloses an intelligent welding device for processing a fuel filter. Through the arrangement of an air frame, a first stirring plate, and a second stirring plate, the rotation of a movable plate drives several air frames to rotate. Since the air frame forms a cross-shaped stirring structure with two first stirring plates and two second stirring plates, the cross-shaped stirring structure can produce a more complex fluid flow pattern, which helps to improve the mixing efficiency, especially in situations where rapid and uniform mixing is required, it can promote rapid and sufficient mixing of inert gas and active gas. Through the arrangement of a guide plate, the downward movement of the movable plate drives several air frames to move downward, and the downward movement of the air frame drives the two first stirring plates and the second stirring plates to move downward. Since the lower end of the second stirring plate is in sliding contact with the upper end inclined surface of the guide plate, the two second stirring plates move downward and are guided by the two guide plates, so that the two second stirring plates are moved away from each other. The two second stirring plates are moved away from each other, thereby increasing the contact area between the cross-shaped stirring structure and the gas, which is conducive to gradually improving the effect of stirring and mixing the gas in the second air cavity.

[0019] An intelligent welding device for processing fuel filters according to the present invention, through the settings of a conical cover, a mounting plate, and a nozzle, the rotation of the conical cover drives the rotation of a plurality of mounting plates and nozzles. The rotation of the plurality of nozzles evenly distributes the mixed protective gas around the welding area of the fuel filter. By evenly spraying the mixed protective gas, it can ensure that the weld is in a protective atmosphere throughout the welding process, thereby avoiding the adverse effects caused by oxidation and nitridation. Furthermore, through the settings of a guide ring and a torsion spring, since the lower side of one end of the nozzle is in sliding contact with the uneven structure on the upper side of the guide ring, the rotation of the nozzle is guided by the upper side of the guide ring and under the elastic force of the torsion spring, enabling the nozzle to swing back and forth. By using the back-and-forth swinging of the plurality of nozzles to expand the coverage area of the mixed protective gas, it is beneficial to fully cover the weld, and can better protect the weld from oxidation, improving the mechanical properties and appearance quality of the weld.

[0036] Preferably, referring to the appendix Figure 7 , a gas processor 34 is arranged on one side of the upper part of the protective cover 17, and the gas processor 34 is communicated with the first air cavity 27.

[0037] Preferably, referring to the appendix Figure 1, a workbench 13 is provided on the upper side of the operation console 10, and an operation panel 12 is provided on one side of the operation console 10.

[0038] In the initial state, the interiors of a number of gas storage frames 35 are respectively filled with inert gas and active gas, and the second gas chamber 28 is filled with a mixed protective gas.

[0039] The specific usage method of the present invention: The staff installs and fixes the fuel filter on the workbench 13. The staff uses the operation panel 12 to control the driving mechanism 15 to start. The driving mechanism 15 drives the laser welding machine 16 to move above the fuel filter. The driving mechanism 15 drives the laser welding machine 16 to move downward. The downward movement of the laser welding machine 16 drives the protective cover 17, the movable ring 19, and the annular member 18 to move downward. The downward movement of the annular member 18 contacts the upper side of the workbench 13. At this time, the annular member 18 is resisted by the upper side of the workbench 13, and the protective cover 17 continues to move downward, so that the movable ring 19 slides within the protective cover 17. The sliding of the movable ring 19 compresses a number of compression springs 21 to generate elastic force. The elastic force generated by the number of compression springs 21 acts on the movable ring 19 and the annular member 18, so that the annular member 18 presses on the upper side of the workbench 13, so as to use the protective cover 17, the movable ring 19, the annular member 18, and the workbench 13 to protect the periphery of the laser welding machine 16, reduce the waste gas generated by the laser welding machine 16 from overflowing into the air, and prevent air pollution.

[0040] Secondly, the laser welding machine 16 is started to perform welding work on the fuel filter, and the driving mechanism 15 is used to drive the laser welding machine 16 to move horizontally. At this time, the operation panel 12 controls the air extraction assembly to start. The stepping motor 50 starts to drive the circular plate 51 to rotate. The rotation of the circular plate 51 drives the Z-shaped connecting rod 52 to revolve. One end of the Z-shaped connecting rod 52 is rotatably connected to the circular plate 51, and the other end of the Z-shaped connecting rod 52 is rotatably connected to the upper end of the connecting rod 49. Therefore, the revolution of the Z-shaped connecting rod 52 drives the connecting rod 49 to move up and down. The up and down movement of the connecting rod 49 drives the fixed ring 48 and the movable plate 26 to move up and down. Since the outer wall of the movable plate 26 is in threaded contact with the inner wall of the fixed cylinder 25, the up and down movement of the movable plate 26 is guided by the thread on the inner wall of the fixed cylinder 25, so that the movable plate 26 moves up and down and rotates. Among them, the rotation of the movable plate 26 drives the fixed ring 48 to rotate. Since the lower end of the connecting rod 49 slides annularly within the fixed ring 48, the rotation of the fixed ring 48 cannot drive the connecting rod 49 to rotate, so that the up and down movement of the connecting rod 49 is not affected.

[0041] Meanwhile, the rotation of the movable plate 26 drives the rotation of a number of air frames 29. Since the air frames 29 and two first stirring plates 44 and two second stirring plates 45 form a cross-shaped stirring structure, the cross-shaped stirring structure can generate a more complex fluid flow pattern, which helps to improve the mixing efficiency. Especially in the occasions where rapid and uniform mixing is required, it can promote the rapid and sufficient mixing of inert gas and reactive gas.

[0042] Meanwhile, the rotation of the movable plate 26 drives the rotation of a number of air frames 29. The lower part of the air frame 29 slides in the through opening 31, so that the rotation of a number of air frames 29 drives the rotation of the conical cover 22, and the rotation of the conical cover 22 drives the limit ring 23 to slide annularly on the inner wall of the protective cover 17, so as to make the conical cover 22 rotate smoothly.

[0043] When the movable plate 26 moves downward, a negative pressure is generated in the first air chamber 27. The waste gas generated by the laser welding machine 16 is absorbed into the air frame 29 by a number of first one-way valves 30, and the waste gas in the air frame 29 moves into the first air chamber 27. The downward movement of the movable plate 26 drives the downward movement of a number of air frames 29, so that a number of first one-way valves 30 gradually approach the welding part of the laser welding machine 16, thus realizing the absorption of waste gas at a short distance, which is beneficial to quickly absorb a large amount of waste gas generated at the welding part of the laser welding machine 16. Moreover, the rotation of the movable plate 26 drives the rotation of a number of air frames 29, and the rotation of a number of air frames 29 drives a number of first one-way valves 30, so that a number of first one-way valves 30 rotate around the laser welding machine 16. By using the continuous change of the positions of a number of first one-way valves 30 in the vertical direction and the circumferential direction, the waste gas in the protective cover 17 can be quickly absorbed into the first air chamber 27, avoiding the overflow of waste gas from the protective cover 17 and preventing air pollution.

[0044] Meanwhile, the downward movement of the movable plate 26 drives the downward movement of a number of air frames 29, and the downward movement of the air frames 29 drives the two first stirring plates 44 and the second stirring plates 45 to move downward. Since the lower end of the second stirring plate 45 is in sliding contact with the inclined surface at the upper end of the guide plate 47, the downward movement of the two second stirring plates 45 is guided by the two guide plates 47, so that the two second stirring plates 45 move away from each other. The two second stirring plates 45 move away from each other, thus increasing the contact area between the cross-shaped stirring structure and the gas, which is beneficial to gradually improve the stirring and mixing effect of the gas in the second air chamber 28. Among them, the second stirring plate 45 slides in the first stirring plate 44 to stretch the second spring 46 to generate elastic force, and under the elastic force of the second spring 46, the second spring 46 can move back to its original position.

[0045] Next, the movable plate 26 moves downward to squeeze the mixed shielding gas in the second air chamber 28 into a number of connecting channels 37. The mixed shielding gas in the connecting channels 37 enters the spray head 39 through the telescopic tube 40, and the spray head 39 sprays the mixed shielding gas around the welding area of the fuel filter. The mixed shielding gas combines the advantages of different gases, can better protect the weld from oxidation, and improve the mechanical properties and appearance quality of the weld. Moreover, the ratio of the mixed shielding gas can be adjusted according to different material characteristics to meet the welding requirements of various metal materials. Among them, the lower sides of both ends of the air frame 29 are respectively in inclined contact with the inclined surfaces of the two mutually approaching ends of the two sliding plates 32. When the air frame 29 moves downward, it guides the two sliding plates 32 to move away from each other. The two sliding plates 32 move away from each other respectively to compress the two first springs 33 to generate elastic forces. Under the elastic forces of the two first springs 33, the mutually approaching ends of the two sliding plates 32 are always in contact with the lower sides of both ends of the air frame 29, so as to realize the sealing effect on the through port 31 and prevent the waste gas from entering the second air chamber 28 through the through port 31.

[0046] At the same time, the conical cover 22 rotates to drive a number of mounting plates 38 and spray heads 39 to rotate. The rotation of the number of spray heads 39 makes the mixed shielding gas evenly distributed around the welding area of the fuel filter. By evenly spraying the mixed shielding gas, it can ensure that the weld is in a protected atmosphere throughout the welding process, thus avoiding the adverse effects caused by oxidation and nitridation. Moreover, since the lower side of one end of the spray head 39 is in sliding contact with the uneven structure on the upper side of the guide ring 42, the rotation of the spray head 39 is guided by the upper side of the guide ring 42 and under the elastic force of the torsion spring 43, the spray head 39 can swing back and forth. By using the back-and-forth swing of the number of spray heads 39 to expand the coverage area of the mixed shielding gas, it is beneficial to fully cover the weld, can better protect the weld from oxidation, and improve the mechanical properties and appearance quality of the weld.

[0047] When the movable plate 26 moves upward, a negative pressure is generated inside the second air chamber 28. The three second one-way valves 36 are used to absorb the gas in the three gas storage frames 35 into the second air chamber 28 in a certain proportion, so as to supplement the mixed shielding gas in the second air chamber 28. Moreover, when the movable plate 26 moves upward, the waste gas in the first air chamber 27 is squeezed into the gas processor 34, and the gas processor 34 is used to process the waste gas to avoid the situation of direct emission of the waste gas into the air and causing air pollution.

[0048] The intelligent welding equipment for processing a fuel filter of the present invention is provided with a protective cover 17, a movable ring 19, an annular member 18, and a compression spring 21. The annular member 18 is resisted by the upper side of the workbench 13, and the protective cover 17 continues to move downward, so that the movable ring 19 slides in the protective cover 17. The sliding of the movable ring 19 compresses a plurality of compression springs 21 to generate elastic force, and the elastic force generated by the plurality of compression springs 21 acts on the movable ring 19 and the annular member 18, so that the annular member 18 is pressed on the upper side of the workbench 13, so that the protective cover 17, the movable ring 19, the annular member 18, and the workbench 13 are used to protect the periphery of the laser welding machine 16, reduce the exhaust gas generated by the laser welding machine 16 from overflowing into the air, and prevent air pollution. Then, through the arrangement of the movable plate 26, the air frame 29, and the first one-way valve 30, the movable plate 26 moves downward, so that the first air cavity 27 generates negative pressure, and the exhaust gas generated by the laser welding machine 16 is absorbed into the air frame 29 by using the first one-way valves 30, and the exhaust gas in the air frame 29 moves into the first air cavity 27. The downward movement of the movable plate 26 drives the downward movement of the air frames 29, so that the first one-way valves 30 gradually approach the welding point of the laser welding machine 16, thereby realizing the absorption of the exhaust gas at a close distance, which is conducive to the rapid absorption of a large amount of exhaust gas generated at the welding point of the laser welding machine 16. Finally, the movable plate 26 rotates to drive the plurality of air frames 29 to rotate, and the rotation of the plurality of air frames 29 drives the plurality of first one-way valves 30, so that the plurality of first one-way valves 30 rotate around the laser welding machine 16. By utilizing the continuous changes in the vertical and circumferential positions of the plurality of first one-way valves 30, the exhaust gas in the protective cover 17 can be quickly absorbed into the first air cavity 27, thereby preventing the exhaust gas from overflowing from the protective cover 17 and preventing air pollution.

[0049] The invention discloses an intelligent welding device for processing a fuel filter. Through the arrangement of an air frame 29, a first stirring plate 44, and a second stirring plate 45, the movable plate 26 rotates to drive several air frames 29 to rotate. Since the air frame 29 forms a cross-shaped stirring structure with two first stirring plates 44 and two second stirring plates 45, the cross-shaped stirring structure can produce a more complex fluid flow pattern, which helps to improve the mixing efficiency, especially in situations where rapid and uniform mixing is required, it can promote rapid and full mixing of inert gas and active gas. Through the arrangement of a guide plate 47, the movable plate 26 moves downward to drive several air frames 29 to move downward, and the air frame 29 moves downward to drive two first stirring plates 44 and second stirring plates 45 to move downward. Since the lower end of the second stirring plate 45 is in sliding contact with the upper end inclined surface of the guide plate 47, the two second stirring plates 45 move downward and are guided by the two guide plates 47, so that the two second stirring plates 45 move away from each other. The two second stirring plates 45 move away from each other, thereby increasing the contact area between the cross-shaped stirring structure and the gas, which is conducive to gradually improving the effect of stirring and mixing the gas in the second air cavity 28.

[0050] An intelligent welding device for processing fuel filters according to the present invention, through the settings of the conical cover 22, the mounting plate 38, and the spray head 39, the rotation of the conical cover 22 drives the rotation of a plurality of mounting plates 38 and spray heads 39. The rotation of the plurality of spray heads 39 evenly distributes the mixed protective gas around the welding area of the fuel filter. By evenly spraying the mixed protective gas, it can ensure that the weld is in a protective atmosphere throughout the welding process, thereby avoiding the adverse effects brought by oxidation and nitridation. Furthermore, through the settings of the guide ring 42 and the torsion spring 43, since the lower side of one end of the spray head 39 is in sliding contact with the uneven structure on the upper side of the guide ring 42, under the guiding of the upper side of the guide ring 42 and the elastic force of the torsion spring 43 during the rotation of the spray head 39, the spray head 39 can swing back and forth. By using the back-and-forth swing of the plurality of spray heads 39 to expand the coverage area of the mixed protective gas, it is beneficial to fully cover the weld, can better protect the weld from oxidation, and improve the mechanical properties and appearance quality of the weld.
