Description

Technical Field

[0001] This application relates to the technical field of resistance welding, and in particular to a resistance welding apparatus with a function of blocking and absorbing welding slag. Background Technology

[0002] The EPB power head is the power source in disc brakes for automobiles.

[0003] The EPB power head includes a housing, multiple gears located inside the housing, housing pins, and motor electrode pins. The housing pins and motor electrode pins need to be welded using a resistance welding machine. In the existing technology, the housing opening is generally placed upwards, and the resistance welding machine moves downwards to weld the housing pins and motor electrode pins. However, impurities such as air and welding slag can easily remain inside the housing or even move to multiple gears, thereby reducing product quality. Summary of the Invention

[0004] In order to improve product quality, this application provides a resistance welding device with a function of blocking and absorbing welding slag.

[0005] This application provides a resistance welding device with a slag-blocking and slag-absorbing function, which adopts the following technical solution: A resistance welding device with slag blocking and absorption function, comprising: The workbench is set on the machine body and has a vertical passage hole. The resistance welding machine is located below the workbench; A stop block is set on the worktable for placing the housing; A vacuuming mechanism is set on the workbench and used to suck up and collect impurities. The housing is placed on the block and abuts against the vacuuming mechanism for positioning. The block, housing, and vacuuming mechanism work together to form a vacuuming chamber that communicates with the outside world only through a passage hole. The vacuuming mechanism is activated to suck up and collect impurities located in the vacuuming chamber. The pressing mechanism is set on the workbench and inserted into and clamped on the housing for positioning; the welding head of the resistance welding machine moves vertically upward through the passage hole to weld the housing pins and motor electrode pins.

[0006] By adopting the above technical solution, the housing is placed on the stop block and positioned against the dust collection mechanism. The stop block, housing, and dust collection mechanism work together to form a dust collection chamber that is connected to the outside world only through the passage hole. The housing pins and motor electrode pins are located inside the dust collection chamber. Impurities inside the housing, on the housing pins, and on the motor electrode pins can fall off under the action of gravity. The pressing mechanism is activated to insert and clamp onto the housing for positioning. The dust collection mechanism is activated to suck up and collect the fallen impurities. The resistance welding machine moves upward so that the welding head moves up and passes through the passage hole to weld on the housing pins and motor electrode pins. If welding slag is generated during the welding process, it can be absorbed and collected by the dust collection mechanism.

[0007] By inverting the housing, impurities inside the housing, on the housing pins, and on the motor electrode pins fall downwards under gravity. Simultaneously, the dust collection mechanism is activated to absorb and collect the fallen impurities. During the welding process, the dust collection mechanism continues to absorb welding impurities. Furthermore, when the welding head of the resistance welding machine moves upwards and passes through the passage hole, it can block and obstruct the passage hole to a certain extent, making the dust collection mechanism more effective and faster in absorbing impurities. This reduces the risk of impurities remaining inside the housing or even moving between gears, further improving product quality.

[0008] Optionally, a clearance groove is provided on the upper surface of the stop block. The gear closest to the housing pin and the motor electrode pin is placed in the clearance groove and prevents impurities from moving to the gear. The welding head of the resistance welding machine extends through the passage hole into the dust collection chamber and then blocks the passage hole and prevents the dust collection chamber from communicating with the outside.

[0009] By adopting the above technical solution, the gears closest to the housing pins and motor electrode pins are placed in the clearance groove for blocking. Thus, all gears can be separated from the dust collection chamber through a single clearance groove, thereby preventing impurities from entering between all gears. Therefore, in conjunction with the dust collection mechanism, the impurities are blocked and adsorbed, which greatly reduces the risk of impurities remaining in the housing and entering between the gears, thereby further improving the quality of the product.

[0010] Optionally, the vacuuming mechanism includes: The dust hood is set on the workbench and positioned against the housing, and has a dust suction space that communicates with the dust suction chamber. The suction hose is mounted on the suction hood and connects to the suction space. The vacuuming component is connected to the vacuum hose and extracts and collects impurities from the vacuuming space.

[0011] By adopting the above technical solution, the dust collection component is connected to the dust collection pipe. When the dust collection component is activated, it extracts and collects impurities in the dust collection space and dust collection chamber, so that the impurities located inside are moved into the dust collection component for absorption. This achieves the absorption and collection of impurities and improves the quality of the product.

[0012] Optionally, it may also include cleaning agency one and / or cleaning agency two; The cleaning mechanism is set on the stop block and tilted towards the housing pins and motor electrode pins to blow air for cleaning, and the welding head of the resistance welding machine enters the dust suction chamber for blowing air for cleaning. The second cleaning mechanism is set on the workbench and passes through the passage hole to blow clean the housing pins and motor electrode pins. After moving to the outside of the passage hole, it blows clean the welding head of the resistance welding machine.

[0013] By adopting the above technical solution, although impurities inside the housing, on the housing pins, and on the motor electrode pins can fall off under the action of gravity, some adhering impurities are still difficult to fall off, thereby increasing the risk of impurities remaining inside the housing and entering between gears, and reducing product quality.

[0014] The first cleaning mechanism is located on the stop block. When the first cleaning mechanism is activated, it tilts upward to blow air onto the housing pins and motor electrode pins for cleaning. At the same time, when the welding head of the resistance welding machine passes through the passage hole into the dust collection chamber, it can also be cleaned by the first cleaning mechanism, causing impurities on the welding head to fall off. The blowing and cleaning can continue during the welding process. The simultaneous activation of the first cleaning mechanism and the dust collection mechanism can further improve the quality of the product.

[0015] Cleaning mechanism two is located on the workbench. When cleaning mechanism two is activated, it extends through the passage hole into the dust collection chamber. Cleaning mechanism two blows air to clean the inside of the housing, the housing pins, and the motor electrode pins. The dust collection mechanism is activated to absorb the fallen impurities. After cleaning mechanism two is completed, it moves down to the outside of the passage hole. Cleaning mechanism two is then used to clean the welding head of the resistance welding machine. The simultaneous activation of cleaning mechanism two and the dust collection mechanism further improves the quality of the product.

[0016] Compared to cleaning mechanism two, cleaning mechanism one has the advantage of being able to continuously clean and blow air during welding, and its simple and stable structure does not require an additional drive source, thus improving the stability and energy efficiency of cleaning. However, its disadvantage is that in order to make way for the movement of the welding head of the resistance welding machine, the position and angle of cleaning mechanism one cannot be well matched with the positions of the housing pins and motor electrode pins, and the cleaning time for the welding head is relatively short, which reduces the cleaning effect on impurities.

[0017] Compared to cleaning mechanism one, cleaning mechanism two has the advantage of cleaning through the passage hole, which improves the cleaning effect of impurities, and the subsequent cleaning time of the welding head can be extended for a longer period of time, thus improving the cleaning effect of impurities. The disadvantage is that the structure is more complex and requires a driving structure to achieve the operation. Also, it is removed during welding, which makes it impossible to continuously clean impurities.

[0018] Therefore, cleaning mechanism one or cleaning mechanism two can be selected according to actual needs. Moreover, the two structures of cleaning mechanism one and cleaning mechanism two do not interfere with each other. Therefore, if cleaning mechanism one and cleaning mechanism two are used in combination, the cleaning effect of impurities can be greatly improved and the quality of products can be improved.

[0019] Optionally, the cleaning mechanism includes: The inlet pipe extends through the baffle into the suction chamber and is used to input gas. Both the inclined nozzle and the horizontal nozzle are mounted on the input pipe. The inclined nozzle is tilted upward toward the housing pins and the motor electrode pins, while the horizontal nozzle is horizontally oriented toward the suction space.

[0020] By adopting the above technical solution, the inclined nozzle tilts upward to blow air and clean the housing pins and motor electrode pins, while the horizontal nozzle blows the impurities that have fallen to the bottom of the dust collection chamber toward the dust collection assembly, thereby achieving a better cleaning effect and improving product quality.

[0021] Optionally, the second cleaning mechanism includes: The movable plate is vertically slidably mounted on the lower surface of the workbench and located on one side of the resistance welding machine; A rotating seat is mounted on a movable plate via a rotating shaft. The cleaning tube is mounted on the rotating seat. The air intake assembly is connected to the cleaning pipe and is retractable. A drive assembly is used to drive the rotating seat to rotate and the moving plate to move. The rotation of the rotating seat drives the cleaning pipe to align with the passage hole. The upward movement of the rotating seat drives the cleaning pipe to pass through the passage hole and position the rotating seat against the lower surface of the workbench. At the same time, the housing is placed on the stop block and against the dust collection mechanism for positioning. The pressing mechanism is inserted into and clamped on the housing for positioning, and the cleaning pipe sprays air to clean the inside of the housing. After the cleaning pipe moves down, it rotates to the outside of the resistance welding machine and aligns with the welding head of the resistance welding machine and sprays air to clean. The cleaning pipe is closed and the welding head of the resistance welding machine moves up to achieve welding.

[0022] By adopting the above technical solution, when welding is required, the drive assembly drives the rotating seat and cleaning tube to rotate, moving them above the resistance welding machine so that the cleaning tube is aligned with the passage hole. The drive assembly then drives the rotating seat and cleaning tube to move upward, allowing the cleaning tube to pass through the passage hole and extend into the dust extraction chamber. The rotating seat is positioned against the worktable. The air intake assembly is activated, and gas is blown out through the cleaning tube for cleaning. After cleaning, the drive assembly drives the moving plate, rotating seat, and cleaning tube to move downward below the passage hole. The drive assembly then drives the rotating seat and cleaning tube to rotate, aligning the cleaning tube with the welding head of the resistance welding machine. This achieves air blowing cleaning of the welding head surface. Once the cleaning is complete, the air blowing stops, and the welding head moves upward for welding, thereby improving product quality.

[0023] Optionally, the driving component includes: A placement platform is set on the lower surface of the workbench, and the movable plate is placed on the placement platform for positioning after it is lowered; The drive gear is mounted on the rotating shaft; The rack is vertically slidably mounted on the worktable and meshes with the drive gear; The lifting block is mounted on the rack and located below the moving plate; A driving component is used to drive the rack to move; the upward movement of the rack and lifting block drives the drive gear and rotating seat to rotate, and the lifting block pushes the rack and moving plate to move upward, so that the cleaning tube passes through the passage hole and the rotating seat abuts against the worktable for positioning.

[0024] By adopting the above technical solution, in the initial state, the moving plate moves downward under the action of gravity and is placed on the placement platform for positioning. The driving component starts to drive the rack and lifting block to move vertically. The movement of the rack drives the rotating shaft and rotating seat to rotate. After the rotating seat has rotated, the lifting block abuts against the lower surface of the moving plate for positioning. The rack continues to move, driving the lifting block to move upward and pushing the moving plate to move upward. Thus, the cleaning tube can be rotated and moved by the cooperation of the driving component and the rack, thereby achieving the cleaning of impurities.

[0025] After cleaning, the rack, drive gear, rotating seat, moving plate, and lifting block move down, allowing the moving plate to be positioned on the placement platform. The rack continues to move down, driving the drive gear, rotating seat, and cleaning tube to rotate, thereby realizing the movement and rotation of the cleaning tube. This improves the stability of the structure, enhances the cleaning effect on impurities, and improves the quality of the product.

[0026] Optionally, a spherical air outlet plate is provided at the end of the cleaning pipe away from the air intake assembly, and multiple air outlet holes are evenly opened on the air outlet plate.

[0027] By adopting the above technical solution, the spherical air outlet plate allows the falling impurities to slide down and fall off. The gas is sprayed out through multiple air outlets, which improves the cleaning effect and reduces the risk of impurities moving to the cleaning tube and then to the next housing, thereby improving the quality of the product.

[0028] Optionally, the pressing mechanism includes: A mobile base that connects to the robot; The slide rail is vertically rotatably mounted on the lower surface of the movable seat; The mounting bracket is horizontally slidably mounted on the lower surface of the slide rail; The positioning component, which is mounted on the mounting base and plugged into and clamped onto the housing, will perform positioning. The positioning block is set on the mounting base and has a V-shaped positioning surface; The sliding block is vertically slidably mounted on the moving base; The positioning wheel is rotatably mounted on the bottom end of the sliding block; The elastic element is connected to the movable seat and the sliding block. In the initial state, the positioning wheel is pressed against the lowest point of the positioning surface for positioning under the elastic force of the elastic element. When the mounting seat is subjected to force, the mounting seat pushes the positioning wheel to move on the positioning surface or rotate relative to the positioning surface for buffering.

[0029] By adopting the above technical solution, the robot starts and drives the moving seat, mounting seat, and positioning component to move, so that the positioning component is inserted and clamped onto the housing for positioning. At the same time, when there is a deviation between the position of the moving seat and the position of the housing, the mounting seat pushes the positioning wheel to move on the positioning surface, or pushes the slide rail and the mounting seat to rotate with the moving seat, so that the positioning wheel rotates with the positioning surface, thereby achieving buffering. After the positioning component is separated from the housing, the positioning wheel moves to the lowest point of the positioning surface under the action of the elastic element, thereby pushing the mounting seat and positioning component to move back and rotate to their original positions, and pushing the positioning surface to fit with the positioning wheel, so that the mounting seat and slide rail rotate back to their original positions. Therefore, buffering can be performed during the clamping process, improving the positioning effect of the pressing mechanism on the housing, housing pins, and resistance welding machine pins, and improving product quality.

[0030] Optionally, the positioning component includes: Two positioning rods are set on the mounting base and inserted into the housing for positioning; The clamping cylinder is mounted on the mounting base; Multiple fingers are positioned on the clamping cylinder and clamped onto the housing for positioning.

[0031] By adopting the above technical solution, multiple positioning rods are moved down and inserted into the housing for positioning. Then, the clamping cylinder is activated to drive multiple fingers to come closer together and clamp onto the housing for positioning. This achieves the positioning of the housing pins and motor electrode pins, improves welding quality, and enhances product quality.

[0032] In summary, this application includes at least one of the following beneficial technical effects: 1. By inverting the housing, impurities inside the housing, on the housing pins, and on the motor electrode pins fall downwards under gravity. Simultaneously, the dust collection mechanism is activated to absorb and collect the fallen impurities. During the welding process, the dust collection mechanism continues to absorb welding impurities. Furthermore, when the welding head of the resistance welding machine moves upwards and passes through the passage hole, it can block and obstruct the passage hole to a certain extent, making the dust collection mechanism more effective and faster in absorbing impurities. This reduces the risk of impurities remaining inside the housing or even moving between gears, further improving product quality.

[0033] 2. By placing the gears closest to the housing pins and motor electrode pins in the clearance groove for blocking, all gears can be separated from the dust collection chamber through a single clearance groove. This prevents impurities from entering between all gears. Therefore, in conjunction with the dust collection mechanism, it can block and adsorb impurities, greatly reducing the risk of impurities remaining in the housing and entering between gears, thereby further improving product quality.

[0034] 3. The first cleaning mechanism continuously cleans and blows air during welding. It has a simple and stable structure and does not require an additional drive source. The second cleaning mechanism cleans through the passage hole, which improves the cleaning effect of impurities. The subsequent cleaning time of the welding head can be extended. The combination of the first and second cleaning mechanisms can greatly improve the cleaning effect of impurities and improve the quality of the product. Attached Figure Description

[0037] The following provides a further detailed description of this application.

[0038] This application discloses a resistance welding device with a function of blocking and absorbing welding slag.

[0039] Example 1, referring to Figures 1-6 The resistance welding device with slag suction and blocking function includes a workbench 11, a resistance welding machine 12, a stop block 13, a dust suction mechanism 2, and a pressing mechanism 3. The workbench 11 is horizontal and its lower surface is fixedly installed on the machine body 1. One or more passage holes 14 are provided on the workbench 11, penetrating the upper and lower surfaces of the workbench 11. The resistance welding machine 12 is located below the workbench 11 and is fixedly installed on the ground. The welding head 121 of the resistance welding machine 12 is set vertically upward. The number of passage holes 14 is the same as the number of welding heads 121 and is set accordingly. When the resistance welding machine 12 is started, it drives the welding head 121 to move vertically. The stop block 13 is fixedly installed on the upper surface of the workbench 11. The dust suction mechanism 2 is set on the upper surface of the workbench 11 and is used to suck up impurities. The pressing mechanism 3 is set on the workbench 11 and is used to press against the upper surface of the housing 8 for positioning.

[0040] The housing 8 is placed on the stop block 13 and positioned against the dust collection mechanism 2, so that the stop block 13, housing 8 and dust collection mechanism 2 cooperate to form a dust collection chamber 15. The dust collection chamber 15 is connected to the outside only through the passage hole 14. Impurities located inside the housing 8 and on the housing pins 17 and motor electrode pins 18 fall off under the action of gravity. The dust collection mechanism 2 is activated to absorb and collect the fallen impurities. The welding head 121 moves vertically upward and extends into the dust collection chamber 15 through the passage hole 14. The welding head 121 blocks the passage hole 14, which is used to weld the housing pins 17 and motor electrode pins 18. During the welding process, the dust collection mechanism 2 continuously absorbs and collects impurities, thereby reducing the risk of impurities remaining inside the housing 8 and at the gears, and improving the quality of the product.

[0041] The upper surface of the stop block 13 is provided with a clearance groove 16, and two limiting blocks are provided on the upper surface of the stop block 13. The housing 8 is placed on the upper surface of the stop block 13, and the two limiting blocks and the dust collection mechanism 2 are respectively positioned against the three adjacent side walls of the housing 8. At the same time, the gear closest to the housing pin 17 and the motor electrode pin 18 is placed in the clearance groove 16, so that the housing pin 17 and the motor electrode pin 18 are separated from the housing 8 and all gears, preventing impurities from moving to the gears. This achieves the dual effect of adsorption and blocking of impurities, thereby greatly reducing the risk of impurities remaining in the housing 8 and moving to the gears, and improving the quality of the product.

[0042] The vacuuming mechanism 2 includes a vacuum hood 21, a vacuum pipe 22, and a vacuuming assembly. The vacuum hood 21 is fixedly installed on the upper surface of the workbench 11. A vacuuming space 23 communicating with the vacuuming chamber 15 is opened on the lower surface of the vacuum hood 21. The housing 8 is placed on the stop block 13 and abuts against the vacuum hood 21 for positioning. The vacuum pipe 22 is fixedly installed on the side wall of the vacuum hood 21 away from the stop block 13 and communicates with the vacuuming space 23. The vacuuming assembly communicates with the vacuum pipe 22 and sucks out impurities located in the vacuuming space 23 for collection. The vacuuming assembly adopts a bag filter or similar existing technology.

[0043] The pressing mechanism 3 includes a movable seat 31, a slide rail 32, a mounting base 33, a positioning component 4, a positioning block 34, a sliding block 35, a positioning wheel 36, and an elastic element. The movable seat 31 is connected to the robot 311, and the robot 311 drives the movable seat 31 to move horizontally and vertically. The movable seat 31 is in a horizontal state, and a vertical rotating shaft is rotatably mounted on the lower surface of the movable seat 31. The slide rail 32 is fixedly mounted on the bottom end of the rotating shaft and is in a horizontal state. The mounting base 33 slides along the length of the slide rail 32 and is mounted on the slide rail 32. The positioning component 4 is set on the mounting base 33 and presses against the housing 8 to perform positioning.

[0044] The positioning component 4 includes two positioning rods 41, a clamping cylinder 42, and multiple fingers 43. The two positioning rods 41 are fixedly installed on the lower surface of the mounting base 33 and are in a vertical position, and are vertically inserted into the housing 8 for positioning. The clamping cylinder 42 is fixedly installed on the lower surface of the mounting base 33, and the multiple fingers 43 are installed on the clamping cylinder 42. When the clamping cylinder 42 is activated, it drives the multiple fingers 43 to move closer to each other and press against the outer wall of the housing 8 for positioning. Alternatively, the clamping cylinder 42 drives the multiple fingers 43 to move away from the housing 8, thereby unlocking the housing 8.

[0045] The positioning block 34 is fixedly installed on the side wall of the mounting base 33 parallel to the sliding direction of the mounting base 33. A V-shaped positioning surface 37 is opened on the top of the positioning block 34 along the length direction of the slide rail 32. The positioning surface 37 passes through the positioning block 34 in a direction perpendicular to the length direction of the slide rail 32. The sliding block 35 is vertically slidably installed on the side wall of the moving base 31 and is located above the positioning block 34. The positioning wheel 36 is rotatably installed on the bottom end of the sliding block 35. The axis of the positioning wheel 36 is perpendicular to the length direction of the slide rail 32.

[0046] The elastic element is a spring. The elastic element is fixedly installed on the top of the sliding block 35 and fixedly connected to the moving seat 31 located above the sliding block 35. The elastic element pushes the sliding block 35 and the positioning wheel 36 to keep them close to the positioning block 34. In the initial state, the positioning wheel 36 is pressed against the lowest point of the positioning surface 37 for positioning under the elastic force of the elastic element.

[0047] During the insertion and clamping of the positioning component 4 onto the housing 8, when the mounting base 33 is subjected to force, it is driven to move on the slide rail 32 to avoid the force. The movement of the mounting base 33 drives the positioning wheel 36 to move upward on the positioning surface 37, driving the positioning rod 41 to move upward and compress the elastic element. Alternatively, the mounting base 33 can be driven to move on the slide rail 32, while the slide rail 32 and the mounting base 33 rotate simultaneously to avoid the force, thereby causing the positioning wheel 36 to move on the positioning surface 37 and rotate relative to the positioning surface 37, i.e., driving the positioning rod 41 to move upward and compress the elastic element. This provides cushioning under force, improving stability during the welding process and enhancing product quality. After the positioning component 4 disengages from the housing 8, the positioning wheel 36 pushes the mounting base 33 back to its original position, and the positioning wheel 36 presses against the lowest point of the positioning surface 37 for positioning, facilitating subsequent positioning of the housing 8.

[0048] The working principle of this application embodiment is as follows: The housing 8 is placed on the stop block 13, and the two limiting blocks and the dust collection cover 21 are positioned against the three adjacent side walls of the housing 8. The pressing mechanism 3 is inserted and clamped on the housing 8 for positioning. Impurities located inside the housing 8, on the housing pin 17 and the motor electrode pin 18 fall off under the action of gravity. The dust collection component is activated so that the fallen impurities are absorbed and collected. The welding head 121 of the resistance welding machine 12 moves vertically upward, passes through the passage hole 14 and extends into the dust collection chamber 15 for welding. During the welding process, the dust collection component continuously sucks up and collects impurities, thereby improving the quality of the product.

[0049] Example 2, refer to Figure 3 , Figures 7-10 The difference between this embodiment and embodiment 1 is that it also includes a first cleaning mechanism 5 and / or a second cleaning mechanism 6; the first cleaning mechanism 5 is set on the stop block 13 and is inclined towards the housing pins 17 and motor electrode pins 18 for air blowing cleaning, and the welding head 121 of the resistance welding machine 12 enters the dust suction chamber 15 for air blowing cleaning; the second cleaning mechanism 6 is set on the workbench 11 and passes through the passage hole 14 to air blow clean the housing pins 17 and motor electrode pins 18, and moves to the outside of the passage hole 14 and then aims at the welding head 121 of the resistance welding machine 12 for air blowing cleaning.

[0050] The cleaning mechanism 5 includes an input pipe 51, an inclined nozzle 52, and a horizontal nozzle 53. A mounting hole 54 communicating with the dust collection chamber 15 is provided on the lower surface of the baffle 13. The input pipe 51 passes through the baffle 13 from the side away from the dust collection cover 21 and extends into the mounting hole 54. The inclined nozzle 52 and the horizontal nozzle 53 are both fixedly installed on the end of the input pipe 51 located in the mounting hole 54. The input pipe 51 inputs gas, and the inclined nozzle 52 tilts upward toward the housing pin 17 and the motor electrode pin 18 to blow air for cleaning. The horizontal nozzle 53 blows air horizontally toward the dust collection space 23 for cleaning. At the same time, the dust collection component is activated to extract and collect fallen impurities.

[0051] The second cleaning mechanism 6 includes a moving plate 61, a rotating seat 62, a cleaning pipe 63, an air intake assembly 64, and a drive assembly 7. A vertical mounting platform 19 is fixedly installed on the lower surface of the workbench 11 and on one side of the resistance welding machine 12. The moving plate 61 is vertically slidably installed on the side wall of the mounting platform 19. A horizontal rotating shaft 66 is rotatably installed on the side wall of the moving plate 61. One end of the rotating seat 62 is fixedly installed on the rotating shaft 66. The cleaning pipe 63 is fixedly installed on the end of the rotating seat 62 away from the rotating shaft 66. The number of cleaning pipes 63 and passage holes 14 are the same and correspondingly arranged. A spherical air outlet plate 65 is provided on the end of the cleaning pipe 63 near the resistance welding machine 12. The air outlet plate 65 is used to block impurities from entering the cleaning pipe 63. Multiple air outlet holes for gas to pass through are evenly opened on the air outlet plate 65.

[0052] The air intake assembly 64 is connected to the cleaning pipe 63 and is in a retractable state. The air intake assembly 64 is located on the side of the rotating base 62 away from the resistance welding machine 12. The air intake assembly 64 includes an air intake pipe 641 and a hose 642. The air intake pipe 641 is fixedly installed on the machine body 1 and is connected to the air source. The hose 642 is connected to the air intake pipe 641 and the cleaning pipe 63 and is made of soft material and is in a retractable state to accommodate the rotation and movement of the cleaning pipe 63.

[0053] The drive assembly 7 is used to drive the rotating seat 62 to rotate and the moving plate 61 to move. The rotating seat 62 rotates to drive the cleaning pipe 63 to align with the passage hole 14, that is, the cleaning pipe 63 is coaxial with the passage hole 14 and the cleaning pipe 63 is located above the resistance welding machine 12. Then the rotating seat 62 moves upward to drive the cleaning pipe 63 to pass through the passage hole 14, and the rotating seat 62 is positioned against the lower surface of the tooling table. At the same time, the housing 8 is placed on the stop block 13 and against the dust suction hood 21 for positioning. The pressing mechanism 3 presses against the housing 8 for positioning. The cleaning pipe 63 sprays air and the dust suction assembly sucks air to clean the inside of the housing 8. After cleaning, the cleaning pipe 63 moves downward and rotates to the outside of the resistance welding machine 12 and is aligned with the welding head 121 of the resistance welding machine 12. It is used to blow air to clean the welding head 121 of the resistance welding machine 12. The cleaning pipe 63 is closed and the welding head 121 of the resistance welding machine 12 moves upward to achieve welding.

[0054] The drive assembly 7 includes a placement platform 71, a drive gear 72, a rack 73, a lifting block 74, and a drive component 75. The placement platform 71 is fixedly installed on the side wall of the mounting platform 19 and located below the moving plate 61. The drive gear 72 is keyed to the rotating shaft 66. The rack 73 is vertically slidably installed on the side wall of the mounting platform 19. The lifting block 74 is fixedly installed on the bottom end of the rack 73 and located below the moving plate 61. The drive component 75 is an electric actuator. The drive component 75 is fixedly installed on the bottom of the mounting platform 19, and the piston rod is set vertically upward and fixedly connected to the bottom of the rack 73.

[0055] In the initial state, the moving plate 61 is lowered and placed on the placement table 71 for positioning. The driving component 75 activates the driving rack 73 and lifting block 74 to move upward. The moving rack 73 drives the driving gear 72, rotating shaft 66, rotating seat 62 and cleaning tube 63 to rotate until the cleaning tube 63 is aligned with the passage hole 14, and the lifting block 74 is positioned against the moving plate 61. The rack 73 continues to move upward, driving the lifting block 74, moving plate 61, rotating seat 62 and cleaning tube 63 to move upward until the cleaning tube 63 passes through the passage hole 14 and extends into the dust suction chamber 15, and the rotating seat 62 is positioned against the lower surface of the worktable 11. The cleaning tube 63 blows air towards the housing pin 17 and motor electrode pin 18 for cleaning.

[0056] After cleaning, the drive unit 75 starts to drive the rack 73 to move down, causing the moving plate 61, drive gear 72, and rotating seat 62 to move down simultaneously until the moving plate 61 is placed on the placement table 71 for positioning. The rack 73 continues to move down, driving the rotating seat 62 to rotate until the cleaning tube 63 rotates to the outside of the resistance welding machine 12 and the cleaning tube 63 is aligned with the welding head 121 of the resistance welding machine 12 for cleaning. After cleaning, the resistance welding machine 12 is started for welding.

[0057] The working principle of this application embodiment is as follows: The housing 8 is placed on the stop block 13 and abuts against the dust cover 21 for positioning. The pressing mechanism 3 is inserted and clamped on the housing 8 for positioning, thereby realizing the placement and positioning of the housing 8. The inclined nozzle 52 is inclined towards the housing pin 17 and the motor electrode pin 18 to blow air and clean them, causing the impurities located inside the housing 8 and on the housing pin 17 and the motor electrode pin 18 to fall off. At the same time, the horizontal nozzle 53 blows the fallen impurities into the dust collection space 23. The dust collection component sucks out the impurities in the dust collection space 23 for collection. At the same time, the inclined nozzle 52, the horizontal nozzle 53 and the dust collection component are activated to suck out the impurities for collection.

[0058] The movable plate 61 is positioned on the placement platform 71. The drive unit 75 starts to drive the rotating seat 62 to rotate. The rotating seat 62 drives the cleaning tube 63 to align with the passage hole 14, and the lifting block 74 is supported on the movable plate 61 for positioning. The drive unit 75 continues to start to drive the movable plate 61 and the cleaning tube 63 to move upward, so that the cleaning tube 63 passes through the passage hole 14 and extends into the dust collection chamber 15. The cleaning tube 63 blows air into the housing 8, housing pins 17 and motor electrode pins 18 to clean them, so that the impurities fall off and are collected by the dust collection component. After cleaning, the drive unit 75 starts to move the cleaning tube 63 downward and then rotate it to the outside of the resistance welding machine 12, and blows air into the welding head 121 of the resistance welding machine 12 to clean it. The welding head 121 moves upward to weld, thereby improving the removal effect of impurities and improving the quality of the product.
