Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a double-sided welding equipment for processing a shielding cover with optimized electric field distribution. Background Art

[0002] With the continuous miniaturization and high performance of electronic devices, shielding covers are increasingly widely used. In many electronic terminal products such as communication devices, smart phones, and tablet computers, the shielding cover plays a key role in protecting the internal circuit from external electromagnetic interference and preventing internal electromagnetic signal leakage. The main function of the shielding cover is to reduce the impact of electromagnetic interference and electromagnetic radiation. While preventing the electromagnetic field generated by internal electronic devices from leaking into the external environment to reduce interference with surrounding devices, it can also absorb and reflect electromagnetic waves to reduce the impact of electromagnetic waves on the circuits and components of internal electronic devices. In addition, the shielding cover can also play a role in heat dissipation. The shielding cover is made of metal materials and has good thermal conductivity, which can dissipate the heat generated during the operation of electronic devices into the external environment, thereby stabilizing the normal operating temperature of electronic devices.

[0003] When the existing device performs double-sided welding on the shielding cover, it usually welds one side of the workpiece first, and then welds the other side of the workpiece by flipping the workpiece or rotating the welding assembly, resulting in the inability to synchronously weld the two sides of the workpiece, thereby reducing the welding efficiency. At the same time, dust will be generated during the welding process. The dust contains various harmful substances, which will cause air pollution and affect air quality if directly discharged into the atmosphere, and will have an adverse impact on the surrounding ecological environment and workers. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A double-sided welding equipment for processing a shielding cover with optimized electric field distribution, including a frame body, and a slide rail is fixedly connected to the inner side of the top of the frame body;

[0005] A fixing component, the fixing component is fixedly installed at the middle of the top of the frame body. There are two slide rails, and the two slide rails are symmetrically arranged with the fixing component as the center. A vertical plate is slidably connected to the outer side of the slide rail. A chute is opened on the side of the vertical plate away from the slide rail. A screw rod is rotatably connected to the inside of the chute. The screw rod is a two-way screw rod, that is, the threads at both ends of the screw rod are opposite. A motor is fixedly connected to the top of the vertical plate, and the output end of the motor is fixedly connected to the screw rod. There are two vertical plates, and the two vertical plates are slidably connected to both ends of the welding component. The vertical plates are symmetrically arranged with the fixing component as the center, and the vertical plates are perpendicular to the welding component. A plurality of vertical plates and the welding component form a quadrilateral;

[0006] A welding component, the welding component is slidably connected to the vertical plate through the chute. There are two welding components, and the two welding components are symmetrically arranged at both ends in the vertical direction of the vertical plate;

[0007] Among them, the welding assembly includes a slider, the slider is threadedly connected to the screw rod, a frame is fixedly connected to the outside of the slider, a fixed frame is slidably connected to the inside of the frame, a fixed rod is fixedly connected to the bottom of the fixed frame, a circular ring is fixedly connected to the bottom of the fixed rod, a ring groove is formed on the outside of the circular ring, the workpiece to be processed is placed on the fixing assembly, the motor is externally powered to work, the motor drives the screw rod to rotate when working, the screw rod drives the slider to slide inside the chute, so that the slider drives the welding piece to move towards the middle of the vertical plate through the frame, so that the welding pieces at both ends move close to the workpiece, and then the workpiece is welded, so that the upper and lower groups of welding pieces are welded simultaneously at the top and bottom of the workpiece to be processed. The synchronism of double-sided welding not only greatly improves the welding efficiency, but also reduces the problem of uneven stress caused by sequential welding. At the same time, by welding on both sides of the workpiece, the connection points and connection area at the weld are increased, ensuring the strength and reliability of the weld. A welding piece is slidably connected to the outside of the ring groove, the slider is located inside the chute, both ends of the frame are fixedly connected to the two sliders on both sides, a guide rod is fixedly connected to the inner wall of the frame, a fixed block is slidably connected to the outside of the guide rod, the guide rod penetrates through the fixed block, the fixed block is fixedly connected to the fixed frame, the number of fixed rods is two, and the two fixed rods are symmetrically arranged with the fixed frame as the center. An air suction assembly is fixedly connected to the middle of the bottom of the fixed frame, the air suction assembly is located inside the circular ring, and an air pump is fixedly connected to the inside of the fixed frame, and the air pump is communicated with the air suction assembly.

[0008] Preferably, the welded part includes a U-shaped block which is slidably connected to the circular ring. A clamping block is fixedly connected to the opening of the U-shaped block. There are two clamping blocks which are symmetrically arranged with the circular ring as the center. The clamping blocks are located inside the annular groove. A L-shaped plate is fixedly connected to the bottom of the U-shaped block. An arc plate is fixedly connected to the outer side of the L-shaped plate. Place the workpiece to be processed on the fixing component. The motor is powered on to work. The motor drives the screw rod to rotate. The screw rod drives the slider to slide inside the chute, so that the welded parts at both ends move closer to the workpiece. The U-shaped block slides inside the annular groove on the circular ring. At the same time, the welding torch drives the cylinder to slide along the inner wall of the notch, thereby adjusting the inclination direction of the welding torch. Adjusting the appropriate inclination direction of the welding torch helps to control the shape and flow direction of the molten pool, so that the weld metal can be evenly distributed in the welding area, forming a good weld appearance. At the same time, through the elastic ring arranged outside the welding torch, it can play a certain supporting role for the welding torch, so that it maintains a relatively stable position when adjusting the inclination direction, and can also help to determine the rotation center of the welding torch, making the adjustment of the inclination direction more accurate and controllable. There are two arc plates which are symmetrically arranged with the L-shaped plate as the center. A notch is opened on one side of the L-shaped plate close to the L-shaped plate. A welding torch is arranged inside the L-shaped plate. A square groove is opened on the outer side of the welding torch close to the arc plate. A cylinder is slidably connected inside the square groove. The cylinder is located inside the notch. The welding torch is slidably connected to the notch through the cylinder. An elastic ring is fixedly connected to the outer side of the welding torch. When the welding torch contacts the welding part, by using the elastic performance of the elastic ring, the elastic ring will automatically adjust its shape according to the shape and position of the weld, so that the welding torch can fit along the curve of the weld, ensuring that the welding arc is always aligned with the center of the weld, improving the accuracy and quality of welding, and can also ensure that an appropriate fitting pressure is always maintained between the welding torch and the weld, ensuring the continuity and stability of welding. The outer side of the elastic ring contacts the inner wall of the L-shaped plate. Limit blocks are fixedly connected to the ends of the L-shaped plate. There are two limit blocks which are fixedly connected to both ends of the L-shaped plate. The elastic ring is located inside the L-shaped plate and the two limit blocks.

[0009] Preferably, the suction assembly includes a cylinder, which is fixedly connected to the bottom of the fixed frame and communicates with the air pump. A trapezoidal cylinder is fixedly connected to the bottom of the cylinder. The trapezoidal cylinder is located inside the ring. A through hole is provided at the bottom of the trapezoidal cylinder, and the number of through holes is multiple. The multiple through holes are evenly distributed around the cylinder. A fixed ring is fixedly connected to the inner wall of the trapezoidal cylinder close to the cylinder. A limiting ring is fixedly connected to the inner wall of the trapezoidal cylinder. The limiting ring is designed in a U shape. A middle block is fixedly connected to the middle of the inside of the trapezoidal cylinder. The trapezoidal cylinder, the fixed ring, the limiting ring and the middle block form a structure of a bent labyrinth. When the air pump works, the soot generated in the welding area is sucked into the inside of the trapezoidal cylinder through the through holes at the bottom of the trapezoidal cylinder. Then the soot passes through the gaps between the fixed ring, the limiting ring and the middle block. At this time, the soot particles are continuously blocked and intercepted in the channel, which can effectively remove a large amount of soot generated during the welding process, reduce the soot concentration in the workshop, and improve the working environment. The middle block is located inside the fixed ring, and the limiting ring is located inside the fixed ring. A cooling pipe is arranged inside the opening of the limiting ring. Since the temperature of the soot generated during the welding process is relatively high, the high-temperature soot will not only affect the soot treatment effect but also may have an adverse impact on the material properties of the bent labyrinth structure. By arranging a cooling pipe inside the trapezoidal cylinder, the cooling medium flowing inside the cooling pipe can absorb the heat of the soot, reducing the temperature of the soot. This helps to improve the aggregation efficiency of the particles in the soot, making it easier for smaller particles to aggregate into larger particles, and thus being more easily removed by means of inertial separation, collision adsorption, etc. The connection between the middle block and the trapezoidal cylinder is set as an arc edge. A filter bag is fixedly connected to the inside of the cylinder. When the gas after passing through the bent labyrinth structure enters the inside of the cylinder and then enters the filter bag, it will generate a certain impact force on the compression spring and the spherical ball inside the filter bag. The impact force of the air flow will cause the compression spring to vibrate, and the vibration of the compression spring will be transmitted to the spherical ball through contact with the spherical ball. The spherical ball collides with the inner wall of the filter bag, which helps to shake off the dust attached to the surface of the filter bag, reduce the residue of dust on the filter bag, and extend the service life of the filter bag. Then the gas passes through the filter bag and finally is discharged through the output end of the air pump. By arranging a spherical ball and a compression spring inside the filter bag, the compression spring has a certain elastic supporting force, which can play a supporting role inside the filter bag, prevent the filter bag from deforming due to air flow pressure or dust accumulation during the filtering process, keep the filter bag in good shape, ensure the smoothness of the filtering channel, and improve the filtering efficiency. A spherical ball is arranged inside the filter bag, and a compression spring is fixedly connected to the inner wall of one end of the cylinder close to the fixed frame. The end of the compression spring away from the cylinder is fixedly connected to the spherical ball.

[0010] Preferably, the fixing component includes a support column. A square plate is fixedly connected to the top of the support column, and the square plate is fixedly connected to the frame body. A through groove is formed in the middle of the top of the square plate. A round rod is slidably connected to the inner wall of the through groove. A return spring is fixedly connected to the inner wall of the through groove. The return spring is sleeved on the outside of the round rod. One end of the round rod is fixedly connected to a clamping block. Place the workpiece to be processed inside the through groove. At this time, under the elastic force of the return spring, the clamping block drives the round rod to move towards the middle, so that the guiding blocks at the ends of adjacent two clamping blocks slide relative to each other inside the clamping groove, and thus the four clamping blocks fixedly clamp the outside of the workpiece, making the workpiece located in the middle of the through groove. At this time, by setting multiple clamping blocks, the workpiece can be accurately positioned at the required position, ensuring that the workpiece will not displace or shake during the welding process, which is beneficial to ensuring the welding accuracy and quality. It can also reduce the welding defects caused by the shaking or vibration of the workpiece during the welding process, helping to improve the welding efficiency. At the same time, by fixing the edge of the workpiece with the clamping block, the degree of freedom of deformation of the workpiece during the welding process can be restricted, reducing the deformation caused by the welding thermal stress, and effectively avoiding defects such as wavy deformation and twisting. The end of the return spring away from the through groove is fixedly connected to the clamping block. The clamping block is located inside the through groove. The number of clamping blocks is four, and the four clamping blocks are evenly distributed inside the through groove. Clamping grooves are formed at both ends of the clamping block. Guide blocks are fixedly connected to both ends of another clamping block. Adjacent two clamping blocks are slidably clamped through the clamping grooves and guide blocks at their ends. A round groove is formed in the middle of the side of the clamping block away from the round rod. A connecting block is fixedly connected to the middle of the inside of the round groove. A spring plate is slidably connected to the outside of the connecting block. A spring plate is provided at the part of the clamping block in contact with the workpiece, so that damage to the surface of the workpiece can be avoided during the clamping process, effectively improving the yield and quality of the workpiece. The number of spring plates is multiple, and the multiple spring plates are symmetrically arranged with the connecting block as the center.

[0011] The present invention provides a double-sided welding device for processing an electric field distribution optimized shielding cover. It has the following beneficial effects:

[0012] First, for the double-sided welding device for processing the electric field distribution optimized shielding cover, through the synchronism of double-sided welding, not only the welding efficiency is greatly improved, but also the problem of stress unevenness caused by sequential welding is reduced. At the same time, by welding on both sides of the workpiece, the number of connection points and the connection area at the weld are increased, ensuring the strength and reliability of the weld.

[0013] Second, for the double-sided welding device for processing the electric field distribution optimized shielding cover, by adjusting the inclination direction of the appropriate welding torch, it helps to control the shape and flow direction of the molten pool, enabling the weld metal to be evenly distributed in the welding area and forming a good weld appearance. At the same time, through the elastic ring provided outside the welding torch, it can play a certain supporting role for the welding torch, keeping it in a relatively stable position when adjusting the inclination direction.

[0014] III. The double-sided welding equipment for processing the shielding cover with optimized electric field distribution forms a bent maze structure through a trapezoidal cylinder, a fixed ring, a limiting ring and an intermediate block. The air pump operates, so that the soot generated in the welding area is sucked into the interior of the trapezoidal cylinder through the through hole at the bottom of the trapezoidal cylinder. Subsequently, the soot passes through the gaps between the fixed ring, the limiting ring and the intermediate block. At this time, the soot particles are continuously blocked and intercepted in the channel, and a large amount of soot generated during the welding process can be effectively removed.

[0015] IV. The double-sided welding equipment for processing the shielding cover with optimized electric field distribution is provided with spherical balls and compression springs inside the filter bag. The compression springs have a certain elastic supporting force and can play a supporting role inside the filter bag to prevent the filter bag from deforming due to air flow pressure or dust accumulation during the filtering process, keep the filter bag in a good shape, ensure the smoothness of the filtering channel and improve the filtering efficiency.

[0032] Among them, the welding assembly 8 includes a slider 81, the slider 81 is threadedly connected to the screw rod 6, a frame 82 is fixedly connected to the outside of the slider 81, a fixed frame 84 is slidably connected to the inside of the frame 82, a fixed rod 86 is fixedly connected to the bottom of the fixed frame 84, a circular ring 87 is fixedly connected to the bottom of the fixed rod 86, a ring groove 811 is formed on the outside of the circular ring 87. Place the workpiece to be processed on the fixing assembly 2, the motor 7 is externally powered to work, the motor 7 drives the screw rod 6 to rotate when working, the screw rod 6 drives the slider 81 to slide inside the chute 5, so that the slider 81 drives the welding piece 88 to move towards the middle of the vertical plate 4 through the frame 82, so that the welding pieces 88 at both ends move closer to the workpiece, and then weld the workpiece, so that the upper and lower two groups of welding pieces 88 weld simultaneously at the top and bottom of the workpiece to be processed. The synchronism of double-sided welding not only greatly improves the welding efficiency, but also reduces the problem of uneven stress caused by sequential welding. At the same time, by welding on both sides of the workpiece, the connection points and connection area at the weld are increased, ensuring the strength and reliability of the weld. A welding piece 88 is slidably connected to the outside of the ring groove 811, the slider 81 is located inside the chute 5, both ends of the frame 82 are fixedly connected to the two sliders 81 on both sides, a guide rod 83 is fixedly connected to the inner wall of the frame 82, a fixed block 85 is slidably connected to the outside of the guide rod 83, the guide rod 83 passes through the fixed block 85, the fixed block 85 is fixedly connected to the fixed frame 84, the number of the fixed rods 86 is two, and the two fixed rods 86 are symmetrically arranged with the fixed frame 84 as the center.

[0033] Second Embodiment, on the basis of the first embodiment, please refer to Figure 5As shown, the welded part 88 includes a U-shaped block 881. The U-shaped block 881 is slidably connected to the circular ring 87. A clamping block 882 is fixedly connected to the opening of the U-shaped block 881. The number of clamping blocks 882 is two, and the two clamping blocks 882 are symmetrically arranged with the circular ring 87 as the center. The clamping block 882 is located inside the annular groove 811. The bottom of the U-shaped block 881 is fixedly connected with an L-shaped plate 883. An arc plate 884 is fixedly connected to the outside of the L-shaped plate 883. Place the workpiece to be processed on the fixing component 2. The motor 7 is powered on to work. The motor 7 drives the screw 6 to rotate. The screw 6 drives the slider 81 to slide inside the chute 5, so that the welded parts 88 at both ends move closer to the workpiece. The U-shaped block 881 slides inside the annular groove 811 of the circular ring 87. At the same time, the welding torch 886 drives the cylinder to slide on the inner wall of the notch 885, thereby adjusting the inclination direction of the welding torch 886. Adjusting the appropriate inclination direction of the welding torch 886 helps to control the shape and flow direction of the molten pool, so that the weld metal can be evenly distributed in the welding area, forming a good weld appearance. At the same time, through the elastic ring 888 arranged outside the welding torch 886, it can play a certain supporting role for the welding torch 886, so that it maintains a relatively stable position when adjusting the inclination direction, and can also help to determine the rotation center of the welding torch, making the adjustment of the inclination direction more accurate and controllable. The number of arc plates 884 is two, and the two arc plates 884 are symmetrically arranged with the L-shaped plate 883 as the center. A notch 885 is opened on one side of the L-shaped plate 883 close to the L-shaped plate 883. A welding torch 886 is arranged inside the L-shaped plate 883. A square groove 889 is opened on the outside of the welding torch 886 close to the arc plate 884. A cylinder is slidably connected inside the square groove 889. The cylinder is located inside the notch 885. The welding torch 886 is slidably connected to the notch 885 through the cylinder. An elastic ring 888 is fixedly connected to the outside of the welding torch 886. When the welding torch 886 contacts the welding place, using the elastic performance of the elastic ring 888, the elastic ring 888 will automatically adjust its shape according to the shape and position of the weld, so that the welding torch 886 can fit along the curve of the weld, ensuring that the welding arc is always aligned with the center of the weld, improving the accuracy and quality of welding, and can also ensure that there is always an appropriate fitting pressure between the welding torch 886 and the weld, ensuring the continuity and stability of welding.

The elastic ring 888 is located inside the L-shaped plate 883 and the two limiting blocks 887.

[0034] The third embodiment is based on the first and second embodiments. Please refer to Figures 6 to 8As shown, the suction component 89 includes a cylinder 891, which is fixedly connected to the bottom of the fixed frame 84. The cylinder 891 is communicated with the air pump 810. The bottom of the cylinder 891 is fixedly connected with a trapezoidal cylinder 892. The trapezoidal cylinder 892 is located inside the ring 87. The bottom of the trapezoidal cylinder 892 is provided with through holes 893. The number of the through holes 893 is multiple, and the multiple through holes 893 are evenly distributed around the cylinder 891. A fixed ring 894 is fixedly connected to the inner wall of the trapezoidal cylinder 892 close to the cylinder 891. A limiting ring 895 is fixedly connected to the inner wall of the trapezoidal cylinder 892. The limiting ring 895 is designed in a U shape. A middle block 899 is fixedly connected to the middle of the inside of the trapezoidal cylinder 892. The trapezoidal cylinder 892, the fixed ring 894, the limiting ring 895 and the middle block 899 form a structure of a bent labyrinth. When the air pump 810 works, the dust generated in the welding area is sucked into the inside of the trapezoidal cylinder 892 through the through holes 893 at the bottom of the trapezoidal cylinder 892. Then the dust passes through the gaps between the fixed ring 894, the limiting ring 895 and the middle block 899. At this time, the dust particles are continuously blocked and intercepted in the channel, which can effectively remove a large amount of dust generated during the welding process, with a high purification efficiency, reduce the dust concentration in the workshop and improve the working environment. The middle block 899 is located inside the fixed ring 894, and the limiting ring 895 is located inside the fixed ring 894. A cooling pipe 896 is arranged inside the opening of the limiting ring 895. Since the temperature of the dust generated during the welding process is relatively high, the high-temperature dust will not only affect the dust treatment effect, but also may have an adverse impact on the material properties of the bent labyrinth structure. By arranging the cooling pipe 896 inside the trapezoidal cylinder 892, the cooling medium flowing inside the cooling pipe 896 can absorb the heat of the dust, reducing the temperature of the dust. This helps to improve the agglomeration efficiency of the particles in the dust, making the smaller particles easier to aggregate into larger particles, and thus easier to be removed by means of inertial separation, collision adsorption, etc. The connection part of the middle block 899 close to the trapezoidal cylinder 892 is set as an arc edge 897. A filter bag 898 is fixedly connected to the inside of the cylinder 891. When the gas after passing through the bent labyrinth structure enters the inside of the cylinder 891 and enters the filter bag 898, it will generate a certain impact force on the compression spring 8911 and the spherical ball 8910 inside the filter bag 898. The impact force of the air flow will cause the compression spring 8911 to vibrate, and the vibration of the compression spring 8911 will be transmitted to the spherical ball 8910 through the contact with the spherical ball 8910. The spherical ball 8910 collides with the inner wall of the filter bag 898, which helps to shake off the dust attached to the surface of the filter bag 898, reduce the residue of the dust on the filter bag 898 and extend the service life of the filter bag 898. Then the gas passes through the filter bag 898 and is finally discharged through the output end of the air pump 810. By arranging the spherical ball 8910 and the compression spring 8911 inside the filter bag 898, the compression spring 8911 has a certain elastic supporting force, which can play a supporting role inside the filter bag 898 to prevent the filter bag 898 from deforming due to the air flow pressure or dust accumulation during the filtering process.Keep the filter bag 898 in good shape, ensure the smoothness of the filter channel, and improve the filtration efficiency. A spherical ball 8910 is arranged inside the filter bag 898. One end of the inner wall of the cylinder 891 close to the fixed frame 84 is fixedly connected with a compression spring 8911, and the end of the compression spring 8911 away from the cylinder 891 is fixedly connected with the spherical ball 8910.,

[0035] For the fourth embodiment, please refer to Figures 9 to 11 As shown in the figure, the fixing assembly 2 includes a support column 21. The top of the support column 21 is fixedly connected with a square plate 22. The square plate 22 is fixedly connected with the frame body 1. A through groove 23 is formed in the middle of the top of the square plate 22. A round rod 27 is slidably connected to the inner wall of the through groove 23. A return spring 28 is fixedly connected to the inner wall of the through groove 23. The return spring 28 is sleeved outside the round rod 27. One end of the round rod 27 is fixedly connected with a clamping block 24. Place the workpiece to be processed inside the through groove 23. At this time, under the elastic force of the return spring 28, the clamping block 24 drives the round rod 27 to move towards the middle, so that the guide blocks 26 at the ends of two adjacent clamping blocks 24 slide relative to each other inside the clamping groove 25. Thus, the four clamping blocks 24 fixedly clamp the outside of the workpiece, making the workpiece located in the middle of the through groove 23. At this time, by setting multiple clamping blocks, the workpiece can be accurately positioned at the required position, ensuring that the workpiece will not displace or shake during the welding process, which is beneficial to ensuring the welding accuracy and quality. It can also reduce the welding defects caused by the shaking or vibration of the workpiece during the welding process, helping to improve the welding efficiency. At the same time, fixing the edge of the workpiece by the clamping block 24 can limit the degree of freedom of deformation of the workpiece during the welding process, reducing the deformation caused by the welding thermal stress, and effectively avoiding defects such as wavy deformation and distortion. The end of the return spring 28 away from the through groove 23 is fixedly connected with the clamping block 24. The clamping block 24 is located inside the through groove 23. The number of clamping blocks 24 is four. The four clamping blocks 24 are evenly distributed inside the through groove 23. Clamping grooves 25 are formed at both ends of the clamping block 24. Guide blocks 26 are fixedly connected to both ends of another clamping block 24. Two adjacent clamping blocks 24 are slidably clamped through the clamping grooves 25 and guide blocks 26 at their ends. A round groove 29 is formed in the middle of the side of the clamping block 24 away from the round rod 27. A connecting block 211 is fixedly connected to the middle of the inside of the round groove 29. A spring plate 210 is slidably connected to the outside of the connecting block 211. The spring plate 210 is arranged at the part of the clamping block 24 in contact with the workpiece, so as to avoid damaging the surface of the workpiece during the clamping process, and can effectively improve the yield and quality of the workpiece. The number of spring plates 210 is multiple. The multiple spring plates 210 are symmetrically arranged with the connecting block 211 as the center.

[0036] During use, place the workpiece to be processed inside the through groove 23. At this time, under the elastic force of the return spring 28, the clamping block 24 drives the round rod 27 to move towards the middle, causing the guide blocks 26 at the ends of adjacent clamping blocks 24 to slide relative to each other inside the card slots 25, so that the four clamping blocks 24 fixedly clamp the outer side of the workpiece, making the workpiece located in the middle of the through groove 23.

[0037] The motor 7 operates with an external power supply. The operation of the motor 7 drives the screw rod 6 to rotate. The screw rod 6 drives the slider 81 to slide inside the chute 5, causing the welding parts 88 at both ends to move closer to the workpiece. The U-shaped block 881 slides inside the annular groove 811 of the ring 87. At the same time, the welding torch 886 drives the cylinder to slide along the inner wall of the notch 885, thereby adjusting the inclination direction of the welding torch 886. Subsequently, the upper and lower groups of welding parts 88 perform welding on the top and bottom of the workpiece to be processed simultaneously.

[0038] During the welding process, the air pump 810 operates, so that the smoke and dust generated in the welding area are sucked into the inside of the trapezoidal cylinder 892 through the through hole 893 at the bottom of the trapezoidal cylinder 892. Subsequently, the smoke and dust pass through the gap between the fixed ring 894, the limiting ring 895 and the intermediate block 899 and enter the inside of the cylinder 891. When the gas enters the filter bag 898, it will generate a certain impact force on the compression spring 8911 and the spherical ball 8910 inside the filter bag 898. The impact force of the air flow will cause the compression spring 8911 to vibrate. The vibration of the compression spring 8911 will be transmitted to the spherical ball 8910 through contact with the spherical ball 8910. The spherical ball 8910 collides with the inner wall of the filter bag 898, which helps to shake off the dust attached to the surface of the filter bag 898 and reduce the residue of dust on the filter bag 898. Subsequently, the gas passes through the filter bag 898 and finally is discharged through the output end of the air pump 810.
