Technical Field

[0001] This invention belongs to the technical field of air valve assembly devices, specifically relating to an automated air valve assembly line. Background Technology

[0002] The main components of a pneumatic valve include a valve body, a valve sleeve, and a magnetic core. For each component, a magnetic tube needs to be pre-assembled for the valve body, and a filter screen needs to be pre-assembled for the valve sleeve. After assembling the valve body, valve sleeve, and magnetic core, internal parts such as sealing rings and lugs also need to be assembled inside the valve body.

[0003] Traditional valve assembly systems only set up assembly equipment for individual processes. After assembling parts on the current processing equipment, the parts are transferred to the next equipment for assembly, without forming a unified and integrated assembly system. This results in frequent transfers and the need for numerous assembly devices, leading to low assembly efficiency and high costs. Summary of the Invention

Detailed Implementation

[0042] Example 1:

[0043] This embodiment describes an automated assembly line for air valves, such as... Figure 1 and Figure 2 As shown, the assembly includes a magnetic tube valve housing assembly device 1, a magnetic core assembly device 2, a valve housing internal parts assembly device 3, a valve sleeve filter screen assembly and welding device 4, and a valve housing and valve sleeve assembly device 5. The magnetic tube valve housing assembly device 1 is used to assemble the magnetic tube inside the valve housing. The discharge end of the magnetic tube valve housing assembly device 1 is connected to the feed end of the valve housing internal parts assembly device 3 through a first assembly transport line 001. The magnetic core assembly device 2 is used to assemble the magnetic core and transfer the magnetic core to the first assembly transport line 001 for assembly with the valve housing. The valve housing internal parts assembly device 3 is used to assemble built-in parts inside the valve housing. The discharge end of the valve housing internal parts assembly device 3 is connected to the feed end of the valve housing and valve sleeve assembly device 5. The valve sleeve filter screen assembly and welding device 4 is used to assemble and weld the filter screen on the outside of the valve sleeve. The discharge end of the valve sleeve filter screen assembly and welding device 4 is connected to the feed end of the valve housing and valve sleeve assembly device 5. The valve housing and valve sleeve assembly device 5 is used to assemble the valve sleeve inside the valve housing.

[0044] Example 2:

[0045] This embodiment is a further optimization based on Embodiment 1, such as... Figure 3 As shown, the magnetic core assembly device 2 includes a rotating platform with a plurality of magnetic core carriers 21 with positioning holes arranged circumferentially on the platform. It also includes a blade feeding device 22, a magnetic core feeding device 23, a magnetic core blade pressing device 24, a magnetic core blowing device 25, and a sleeve transfer device 26 arranged along the rotation direction of the rotating platform. The blade feeding device 22 is used to pick up blades and place them at the bottom of the positioning holes on the magnetic core carriers 21. The magnetic core feeding device 23 is used to horizontally feed magnetic cores facing the correct orientation and adjust the magnetic cores to a vertical, coaxial position. The blade is positioned at the top of the positioning hole; the pressing end of the magnetic core blade pressing device 24 is set corresponding to the positioning hole of the magnetic core carrier 21 and presses the magnetic core and blade downwards; the magnetic core purging device 25 includes a sealing part with an air port set corresponding to the top of the positioning hole of the magnetic core carrier 21 and an air suction part set corresponding to the bottom of the positioning hole of the magnetic core carrier 21. The sealing part is used to seal the positioning hole and the top of the magnetic core, and the air suction part is used to seal the bottom of the positioning hole and suction air for purging; the sleeve transfer device 26 is used to transfer the magnetic core to the magnetic core assembly transport line 001 for assembly with the valve body.

[0046] The rotating platform is equipped with blade loading stations, magnetic core loading stations, magnetic core assembly stations, slag blowing stations, and finished product unloading stations along its circumference. For each station, a magnetic core carrier 21 with positioning holes is provided on the rotating platform. The positioning holes on the magnetic core carrier 21 correspond to the outer diameters of the blade and magnetic core, used for positioning and fixing the blade and magnetic core. A blade loading device 22 is provided on one side of the blade loading station. The blade loading device 22 includes a blade vibrating loading plate, a translation device, and a lifting device. The translation end of the translation device corresponds to the discharge end of the blade vibrating loading plate. A lifting device is provided on the translation end of the translation device. A thumb cylinder for picking up blades is provided on the lifting section of the lifting device. The thumb cylinder grips the blade, and with the cooperation of the horizontal and vertical movements of the translation and lifting devices, the blade is placed at the bottom of the positioning hole on the magnetic core carrier 21. A magnetic core feeding device 23 is positioned on one side of the magnetic core feeding station. This device horizontally picks up the magnetic core, adjusts it to a vertical position, and then places it into the positioning hole, ensuring the bottom of the core contacts the top of the blade. A magnetic core blade pressing device 24 is positioned on one side of the magnetic core assembly station. When the pressing end of the device presses down, it presses down on the top of the magnetic core, pushing the core to press the bottom of the core against the blade, completing the assembly of the magnetic core and blade. A magnetic core blowing device 25 is positioned at the debris blowing station. The sealing part in the blowing device 25 is positioned at the top of the magnetic core, and when pressed down, it seals the top of the magnetic core. The suction section in the magnetic core blowing device 25 is positioned at the bottom of the positioning hole. When the suction section rises, it seals the bottom of the positioning hole and then draws in air, creating a negative pressure inside the magnetic core. At this time, the external airflow blows through the air port on the sealing section from top to bottom through the inside of the magnetic core, thereby blowing out the slag and debris inside the magnetic core. A sleeve transfer device 26 is provided on one side of the finished product unloading station. The sleeve transfer device 26 picks up the assembled magnetic core from the magnetic core carrier 21, assembles it inside the sleeve, and then transfers it to the magnetic core assembly transport line 001 for assembly with the valve body.

[0047] like Figure 7As shown, the sealing part includes a vertical pressing device 251 and a sealing sleeve 252. The pressing end of the vertical pressing device 251 is positioned at the top of the positioning hole, and the sealing sleeve 252 is mounted on the pressing end. The sealing sleeve 252 is positioned on the outside of the magnetic core and has an air port. When the vertical pressing device 251 presses down the sealing sleeve 252, the sealing sleeve 252 wraps around the outside of the magnetic core. At this time, the outer wall of the magnetic core contacts the inner wall of the sealing sleeve 252, thereby sealing the top of the magnetic core. To further improve the sealing effect, an elastic sealing ring is provided on the inner sidewall of the bottom opening of the sealing sleeve 252, making the inner wall of the sealing sleeve 252 fit more tightly with the outer wall of the magnetic core. Furthermore, the vertical pressing device 251 is a vertical pressing cylinder.

[0048] like Figure 7 As shown, the suction unit includes a vertical lifting device 253, a sealing suction cup 254, and a suction device 255. The vertical lifting device 253 is used to drive the sealing suction cup 254 to contact and seal with the bottom of the positioning hole. The sealing suction cup 254 is provided with a suction hole that communicates with the positioning hole. The end of the suction hole away from the positioning hole is connected to the suction device 255.

[0049] After the vertical lifting device 253 raises the sealing suction cup 254, the top of the sealing suction cup 254 fits tightly against the bottom end face of the positioning hole, thus sealing the bottom of the positioning hole. At this time, the top of the air suction hole inside the sealing suction cup 254 connects with the bottom end of the positioning hole. Then, the air suction device 255 performs air suction, creating a negative pressure inside the magnetic core. External air is then drawn into the magnetic core from top to bottom through the air port on the sealing sleeve 252. The airflow from top to bottom blows out the debris inside the magnetic core.

[0050] Furthermore, the vertical lifting device 253 is a lifting cylinder, and the air suction device 255 is an air suction pump.

[0051] like Figure 4 As shown, the magnetic core feeding device 23 includes a magnetic core horizontal feeding device 231, a magnetic core rotating device 232, and a magnetic core translation device 233. The magnetic core horizontal feeding device 231 is used to horizontally eject the magnetic core. The magnetic core rotating device 232 is provided at the discharge end of the magnetic core horizontal feeding device 231. The magnetic core rotating device 232 is used to pick up the horizontal magnetic core and drive the horizontal magnetic core to rotate to a vertical state. The magnetic core translation device 233 is used to pick up the magnetic core rotated to a vertical state by the magnetic core rotating device 232 and translate the magnetic core into a positioning hole on the magnetic core carrier 21.

[0052] The magnetic core horizontal feeding device 231 includes a magnetic core feeding rack 2311, a magnetic core ejection device 2312, and a magnetic core shielding device 2313. The magnetic core feeding rack 2311 has a plurality of horizontal magnetic core placement slots arranged on it. The bottom of the horizontal magnetic core placement slots is provided with a horizontal magnetic core pushing channel. The end of the horizontal magnetic core placement slot near the horizontal magnetic core pushing channel is provided with a magnetic core shielding device 2313 for shielding the magnetic cores and allowing the magnetic cores to enter the horizontal magnetic core pushing channel one by one. The end of the horizontal magnetic core pushing channel is provided with a magnetic core ejection device 2312 for pushing the magnetic cores toward the other end. The other end of the horizontal magnetic core pushing channel is provided with a magnetic core rotating device 232.

[0053] Several horizontal magnetic cores are stacked in a horizontal magnetic core placement slot. A magnetic core blocking device 2313 is installed at the connection between the bottom of the horizontal magnetic core placement slot and the horizontal magnetic core pushing channel. The magnetic core blocking device 2313 includes a telescopic cylinder and a blocking plate. The telescopic cylinder extends and retracts, causing the blocking plate to block or open the bottom of the horizontal magnetic core placement slot, thereby allowing the horizontal magnetic cores to enter the horizontal magnetic core pushing channel in sequence.

[0054] The magnetic core ejection device 2312 includes a horizontal pushing cylinder and a pushing head. The pushing head is slidably disposed inside the horizontal magnetic core pushing channel. The horizontal pushing cylinder drives the pushing head to slide horizontally along the horizontal magnetic core pushing channel, thereby pushing the horizontal magnetic core inside the horizontal magnetic core pushing channel to the other end for discharge.

[0055] Furthermore, a foolproof limiting plate is provided at the top of the horizontal magnetic core placement slot, and a foolproof limiting chamfer is provided on the foolproof limiting plate corresponding to the magnetic core. The foolproof limiting chamfer is provided at one end of the magnetic core, thereby pre-positioning the orientation of the magnetic core through physical limiting.

[0056] The magnetic core rotating device 232 includes a stepper rotary motor 2321 and a magnetic core rotating sleeve 2322. The magnetic core rotating sleeve 2322 is provided on the rotating end of the stepper rotary motor 2321. The magnetic core rotating sleeve 2322 is uniformly provided with directional magnetic core sleeves corresponding to the discharge end of the magnetic core horizontal feeding device 231 along the circumferential direction. The directional magnetic core sleeve is provided with a built-in pneumatic clamp inside. The built-in pneumatic clamp clamps the magnetic core with the correct orientation and does not clamp the magnetic core with the incorrect orientation.

[0057] Driven by a stepper motor 2321, the magnetic core rotating sleeve 2322 rotates, aligning its circumferentially oriented magnetic core sleeve with the discharge end of the horizontal magnetic core pushing channel. Then, the magnetic core ejection device 2312 pushes the horizontal magnetic core into the oriented magnetic core sleeve. After entering the oriented magnetic core sleeve, the horizontal magnetic core is clamped and fixed by a built-in pneumatic clamp. The stepper motor 2321 then rotates the magnetic core rotating sleeve 90 degrees, adjusting the horizontal magnetic core to a vertical position. The vertical magnetic core can then be picked up and transferred into the positioning hole by the magnetic core translation device 233.

[0058] like Figure 5 As shown, the built-in pneumatic clamp includes a directional micro switch k1, a pneumatic chuck k2, an air inlet valve k3, an air outlet valve k4, a return spring k5, and an air intake pump k6. The bottom of the directional magnetic core sleeve is provided with a directional micro switch k1. The side wall of the directional magnetic core sleeve is provided with a radial mounting groove and an air inlet channel and an air outlet channel connected to the radial mounting groove. The pneumatic chuck k2 is slidably disposed in the radial mounting groove. A return spring k5 is disposed between the pneumatic chuck k2 and the bottom of the radial mounting groove. The air inlet end of the air inlet channel is connected to the air intake pump k6. An air inlet valve k3 is disposed on the air inlet channel. An air outlet valve k4 is disposed on the air outlet channel.

[0059] A chamfered groove is provided on one side of the directional micro switch k1, corresponding to the chamfer at one end of the magnetic core. When the horizontal magnetic core is correctly oriented and enters the directional magnetic core sleeve, the chamfer squeezes the chamfered groove, causing the directional micro switch k1 to conduct. At this time, the external controller controls the air inlet valve k3 to open and the exhaust valve k4 to close, and the suction pump k6 draws in air. This airflow enters the radial mounting groove and pushes the pneumatic chuck k2 radially along the directional magnetic core sleeve, thus clamping and fixing the magnetic core inside the directional magnetic core sleeve. After the magnetic core rotates to a vertical position, the external controller controls the exhaust valve k4 to open and the air inlet valve k3 to close, and the suction pump k6 to close. At this time, the gas inside the radial mounting groove is discharged, and the return spring k5 drives the pneumatic chuck k2 to retract and reset, thereby releasing the magnetic core so that the magnetic core translation device 233 can pick it up.

[0060] If the horizontal magnetic core enters the directional magnetic core sleeve in the wrong orientation, the end of the magnetic core cannot press the chamfered groove on the directional micro switch k1. At this time, the directional micro switch k1 is not conducting, so the pneumatic chuck k2 will not extend radially to clamp the magnetic core. When the magnetic core rotates with the directional magnetic core sleeve to the bottom of the magnetic core rotating sleeve, the magnetic core will fall into the NG area for recycling.

[0061] like Figure 6As shown, the magnetic core blade pressing device 24 includes a stamping cylinder 241, a stamping head 242, and a stamping straightener 243. The stamping cylinder 241 and the stamping straightener 242 are coaxially arranged on the upper and lower sides of the positioning hole. The stamping end of the stamping cylinder 241 is provided with a stamping head 242 corresponding to the top of the magnetic core. The rotating platform is also provided with a straightening hole for the stamping end of the stamping cylinder 241 to press down and pass through.

[0062] When the magnetic core and blade need to be pressed together, the stamping cylinder 241 drives the stamping head 242 to press down, causing the stamping head 242 to push the top of the magnetic core downwards, thereby pressing the bottom of the magnetic core together with the blade. When the number of stampings by the stamping cylinder 241 reaches a preset threshold, the stamping direction of the stamping cylinder 241 needs to be corrected. At this time, the rotating platform rotates, causing the correction hole to move between the stamping cylinder 241 and the stamping corrector 243. Then, the stamping end of the stamping cylinder 241 drives the stamping head 242 to press down through the correction hole and press against the correction port on the stamping corrector 243, thereby axially correcting the stamping head 242 through the correction port.

[0063] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again.

[0064] Example 3:

[0065] This embodiment is a further optimization based on the above embodiment 1 or 2, such as... Figure 8 As shown, the valve housing internal component assembly device 3 includes a rotating platform, a valve housing picking device 31 disposed on one side of the rotating platform along the rotation direction, and several internal component assembly devices 33. Several valve housing carriers 32 are evenly disposed on the rotating platform along the circumference. The valve housing carriers 32 rotate cyclically between the valve housing picking device 31 and the several internal component assembly devices 33 as the rotating platform rotates. The valve housing picking device 31 is used to pick up the valve housing from the discharge end of the first assembly transport line 001 and place the valve housing on the valve housing carrier 32. The internal component assembly devices 33 are used to pick up the built-in parts and assemble the built-in parts inside the valve housing.

[0066] Furthermore, such as Figure 9 As shown, the internal component assembly device 33 includes a translation device 331, a main lifting device 332, an auxiliary lifting device 333, and an internal expansion pickup device 334. The translation part of the translation device 331 is provided with the main lifting device 332, the lifting part of the main lifting device 332 is provided with the auxiliary lifting device 333, and the lifting part of the auxiliary lifting device 333 is provided with the internal expansion pickup device 334. The internal expansion part of the internal expansion pickup device 334 is used to pick up the internal component and assemble the internal component into the valve body.

[0067] The rotating platform is equipped with a machining station corresponding to several internal component assembly devices 33. A valve housing carrier 32 is installed on the machining station to position and fix the valve housing.

[0068] The translation device 331 moves linearly between the valve body loading area and the top of the assembly platform, while the main lifting device 332 performs rapid, large-stroke vertical lifting to quickly pick up the valve body. The auxiliary lifting device 333 performs precise, small-stroke numerical lifting to avoid damage to the valve body during internal component assembly. The internal expansion picking device 334 picks up annular or hollow internal components through internal expansion, avoiding interference with the valve body's inner wall caused by traditional external clamping methods.

[0069] The valve body internal parts assembly requires three processes: folding lug assembly, sealing ring assembly, and cap assembly. Around the rotating platform, three internal parts assembly devices 33 are arranged circumferentially. The three internal parts assembly devices 33 pick up the folding lug, sealing ring, and cap respectively. With the rotation of the rotating platform, the valve body moves between the corresponding workstations of the three processes, thereby realizing continuous, efficient, and precise assembly of the folding lug, sealing ring, and cap of the valve body.

[0070] like Figure 10 As shown, the internal expansion pickup device 334 includes a pneumatic mounting base 3341, internal expansion grippers 3342, and gripper traction device 3343. The bottom of the pneumatic mounting base 3341 is evenly provided with a plurality of internal expansion grippers 3342 that slide along the circumferential diameter direction. The interior of the pneumatic mounting base 3341 is provided with an inner cavity with an air port along the axial direction. The gripper traction device 3343 is slidably arranged in the inner cavity along the axial direction. The bottom of the gripper traction device 3343 extends to the outside of the inner cavity and contacts the plurality of internal expansion grippers 3342 synchronously. When the gripper traction device 3343 extends downward, it drives the plurality of internal expansion grippers 3342 to expand away from the center along the diameter direction. When the gripper traction device 3343 retracts upward, it drives the plurality of internal expansion grippers 3342 to close together towards the center along the diameter direction.

[0071] The bottom of the pneumatic mounting base 3341 is evenly provided with several sliding grooves along its circumference. The sliding grooves are arranged along the diameter passing through the center of the circle, and the top of the internal expansion grippers 3342 is slidably connected to the sliding grooves. The pneumatic mounting base 3341 is provided with a first air port and a second air port connected to the inner cavity. When air enters through the first air port and exhausts through the second air port, the downward air pressure drives the gripper traction device 3343 to extend downward, thereby causing the several internal expansion grippers 3342 to expand away from the center along the diameter, realizing the internal expansion pickup of the inner part. When air exhausts through the first air port and enters through the second air port, the upward air pressure drives the gripper traction device 3343 to retract upward, thereby causing the several internal expansion grippers 3342 to close together closer to the center along the diameter, releasing the inner part.

[0072] The gripper traction device 3343 includes a pneumatic piston, a traction rod, and a traction head. The pneumatic piston is slidably disposed in the inner cavity of the pneumatic mounting base. The bottom of the pneumatic piston is provided with a traction rod extending to the outer side of the inner cavity. The bottom of the traction rod is provided with a traction head. From top to bottom, the bottom end of the traction head is provided with an expansion plate and a closing plate. The bottom edge of the expansion plate is provided with a downwardly inclined expansion compression wedge, and the top edge of the closing plate is provided with an upwardly inclined closing compression wedge. From top to bottom, the inner expansion gripper is provided with an expansion pressure inclined surface that cooperates with the expansion compression wedge and a closing pressure inclined surface that cooperates with the closing compression wedge.

[0073] When air enters through the first port and exits through the second port, the air pressure pushes the pneumatic piston downwards, which in turn drives the traction head downwards via the traction rod. At this time, the expansion wedge on the expansion plate outside the traction head presses downwards against the expansion pressure slope on the inner expansion jaw 3342, while the closing wedge on the closing plate disengages from the closing pressure slope. This causes the inner expansion jaw 3342 to slide and expand along the groove under an outward thrust. When air exits through the first port and enters through the second port, the air pressure pushes the pneumatic piston upwards, which in turn drives the traction head upwards via the traction rod. At this time, the expansion wedge on the expansion plate outside the traction head disengages from the expansion pressure slope on the inner expansion jaw 3342, while the closing wedge on the closing plate presses upwards against the closing pressure slope. This causes the inner expansion jaw 3342 to slide and close along the groove under an inward thrust.

[0074] It also includes a limiting plate at the bottom of the pneumatic mounting base 3341. An expansion limiting groove is provided on the limiting plate along the sliding direction of the inner expansion claw 3342. The bottom of the inner expansion claw 3342 passes downward through the expansion limiting groove. A closing limiting block is provided circumferentially at the bottom of the limiting plate corresponding to the position between adjacent inner expansion claws 3342.

[0075] When the internal expansion jaws 3342 slide along the sliding groove, they continue to slide until one side of the internal expansion jaws 3342 contacts the end of the expansion limiting groove. The expansion limiting groove limits the expansion sliding stroke of the internal expansion jaws 3342, preventing them from over-expanding and damaging the internal components and valve body. Similarly, when the internal expansion jaws 3342 slide close along the sliding groove, they continue to slide until adjacent internal expansion jaws 3342 contact both sides of the closing limiting block. The closing limiting block limits the closing sliding stroke of the internal expansion jaws 3342, preventing them from over-closing and causing them to squeeze and damage each other.

[0076] Furthermore, a guide cone surface is provided on the bottom outer side of the closing limiting block, and the guide cone surface is provided with a chamfer on the top inner hole of the valve body. Through the cooperation of the guide cone surface and the chamfer, a certain guiding effect is achieved.

[0077] like Figure 11 As shown, the valve body pickup device 31 includes an X-axis translation device 311, a Y-axis translation device 312, a first Z-axis lifting device 313, and a second Z-axis lifting device 314. The translation part of the X-axis translation device 311 is respectively provided with the Y-axis translation device 312 and the first Z-axis lifting device 313, and the translation part of the Y-axis translation device 312 is provided with the second Z-axis lifting device 314. The lifting parts of the first Z-axis lifting device 313 and the second Z-axis lifting device 314 are each provided with a telescopic clamping device 315.

[0078] An X-axis translation frame is provided on the translation part of the X-axis translation device 311. A Y-axis translation device 312 is provided on the X-axis translation frame along the Y direction. At the same time, a first Z-axis lifting device 313 is provided on one side of the end of the X-axis translation frame. The translation part of the X-axis translation device 311 drives the Y-axis translation device 312 and the first Z-axis lifting device 313 to translate in the X direction. The first Z-axis lifting device 313 is set at the unloading station of the rotating platform. The first Z-axis lifting device 313 drives the telescopic clamping device 315 to directly pick up the assembled valve body at the unloading station.

[0079] A second Z-axis lifting device 314 is provided on the translation part of the Y-axis translation device 312. Through the translational cooperation of the X-axis translation device 311 and the Y-axis translation device 312, the second Z-axis lifting device 314 can be driven to translate along the X and Y axes. The second Z-axis lifting device 314 is set at the valve shell loading station. The lifting of the second Z-axis lifting device 314 itself drives the telescopic clamping device 315 to directly pick up the hollow valve shell on the valve shell loading station.

[0080] Furthermore, the telescopic clamping device 315 includes a telescopic cylinder, a pneumatic clamp, a thumb cylinder, a slidingly connected slider and a slide rail. A slider is provided on one side of the telescopic cylinder, and the slide rail is provided on the lifting parts of the first Z-axis lifting device 313 and the second Z-axis lifting device 314. A thumb cylinder is provided at the telescopic end of the telescopic cylinder, and an openable pneumatic clamp is provided at the bottom of the thumb cylinder.

[0081] Furthermore, a visual inspection device is also provided on one side of the rotating platform corresponding to the unloading station. The visual inspection device includes a visual inspection camera, which takes pictures of the inside of the valve body and determines whether the internal parts are installed in place based on the pictures.

[0082] The other parts of this embodiment are the same as those in Embodiment 1 or 2 above, so they will not be described again.

[0083] Example 4:

[0084] This embodiment is a further optimization based on any one of embodiments 1-3 above, such as... Figure 12As shown, the valve sleeve filter screen assembly and welding device 4 includes a welding platform 41 with several workstations arranged sequentially. A valve sleeve positioning groove 01 and several filter screen positioning grooves 02 perpendicularly intersecting the valve sleeve positioning groove 01 are provided at the center of each workstation on the welding platform 41. A filter screen picking device 42 is provided on one side of the welding platform 41 corresponding to the filter screen positioning groove 02, and the filter screen is placed inside the filter screen positioning groove 02 by the filter screen picking device 42. A stepping valve sleeve transfer device 43 is provided on the other side of the welding platform 41 corresponding to the valve sleeve positioning groove 01. A filter screen attaching and assembly device 44 is provided on the welding platform 41 corresponding to each valve sleeve positioning groove 01 and filter screen positioning groove 02, which pushes the filter screen to adhere to the outside of the valve sleeve. A moving welding device 45 is provided on the top of the valve sleeve positioning groove 01.

[0085] One end of the welding platform 41 is the loading end, and the other end is the unloading end. Several workstations are set between the loading end and the unloading end to correspond to the processing steps. A valve sleeve positioning groove 01, corresponding to the outer contour of the valve sleeve, is set at the center of each workstation, parallel to the axial direction of the valve sleeve. The valve sleeve is positioned by directly placing it in the valve sleeve positioning groove 01. Simultaneously, since a filter screen needs to be wound circumferentially around the outside of the valve sleeve, a filter screen positioning groove 02 is also set perpendicular to the valve sleeve positioning groove 01. This ensures that the filter screen positioning grooves 02 and the valve sleeve positioning groove 01 are perpendicular to each other and intersecting. The number and position of the filter screen positioning grooves 02 correspond to the number and position of the filter screens to be wound, and the inner contour of the filter screen positioning groove 02 matches the outer contour of the filter screen.

[0086] When installing a filter screen on the outside of the valve sleeve, first wind up the central filter screen located in the middle of the outer side of the valve sleeve, and then wind up the side filter screens located on both sides of the middle of the outer side of the valve sleeve. Three filter screen positioning grooves 02 are provided perpendicular to the valve sleeve positioning groove 01, including a central filter screen positioning groove corresponding to the central filter screen, and side filter screen positioning grooves located on both sides of the central filter screen positioning groove. First, the central filter screen is picked up by the filter screen picking device 42 and placed inside the central filter screen positioning groove. Then, the valve sleeve is picked up by the stepping valve sleeve transfer device 43 and placed inside the valve sleeve positioning groove 01, so that the valve sleeve presses down on top of the central filter screen. Then, the central filter screen is pushed towards the valve sleeve by the filter screen attachment assembly device 44, thereby pressing the central filter screen onto the outside of the valve sleeve by external force. Finally, the joint of the pressed central filter screen is welded by the moving welding device 45.

[0087] After the center filter screen is wound and welded, the filter screen pick-up device 42 places the side filter screens in the two side filter screen positioning slots at the next station. Then, the stepping valve sleeve transfer device 43 moves the valve sleeve to the next station and places it inside the valve sleeve positioning slot 01, so that the valve sleeve presses down on the top of the side filter screen. Then, the filter screen attaching and assembling device 44 pushes the side filter screen towards the valve sleeve, thereby pressing the side filter screen onto the outside of the valve sleeve by external force. Then, the moving welding device 45 welds the joint of the pressed side filter screen, thus completing the assembly of the filter screen on the outside of the valve sleeve. Finally, the stepping valve sleeve transfer device 43 picks up the processed valve sleeve and moves it to the unloading end of the welding platform 41 for unloading.

[0088] Furthermore, such as Figure 13 As shown, the filter screen attachment assembly device 44 includes a bottom filter screen pushing device 441 and a side filter screen pushing device 442. The bottom filter screen pushing device 441 is positioned at the top of the valve sleeve positioning groove 01, corresponding to the position of the filter screen positioning groove 02. The pushing end of the bottom filter screen pushing device 441 extends and retracts upward through the valve sleeve positioning groove 01 to push the filter screen upward, so that the filter screen is attached to the bottom of the valve sleeve. The side filter screen pushing device 442 is symmetrically positioned on both sides of the valve sleeve positioning groove 01, corresponding to the position of the filter screen positioning groove 02. The pushing end of the side filter screen pushing device 442 extends and retracts perpendicular to the valve sleeve positioning groove 01 to attach the filter screen as a whole to the outer surface of the valve sleeve.

[0089] When the valve sleeve is first placed on top of the filter screen, the filter screen is in a flat state. Then, the bottom filter screen pushing device 441 pushes the filter screen upward, causing the two sides of the filter screen to bend and deform upward and wrap around the bottom of the valve sleeve. At this time, the two sides of the filter screen form a U-shape under the action of the upward external force.

[0090] The U-shaped filter screen is pushed against the sides by the side filter screen pushing devices 442 on both sides, so that the U-shaped filter screen wraps around and fits against the outside of the valve sleeve along the circumference, thereby realizing the winding of the filter screen. Then, the joint of the filter screen can be welded by the moving welding device 45.

[0091] Furthermore, such as Figure 13 , Figure 17 , Figure 18 , Figure 19As shown, the bottom filter screen pushing device 441 includes a vertical pushing cylinder 4411 and a bottom pushing block 4412. The vertical pushing cylinder 4411 is located at the bottom of the valve sleeve positioning groove 01. The push rod end of the vertical pushing cylinder 4411 is provided with a bottom pushing block 4412. The top center of the bottom pushing block 4412 is provided with a limiting groove corresponding to the outer contour of the valve sleeve. Bottom pushing protrusions are provided on both sides of the limiting groove at positions corresponding to the filter screen positioning groove 02.

[0092] The limiting groove at the top center of the bottom push block 4412 is used to avoid the installation space of the valve sleeve. At the same time, the limiting groove limits the movement of the valve sleeve to prevent large left and right swings during the winding of the filter screen, thus ensuring the stability of the valve sleeve to a certain extent. Meanwhile, a flexible pad is provided on the pushing surface of the bottom push protrusion to avoid rigid contact with the filter screen and prevent damage. Driven by the vertical push cylinder 4411, the bottom push block 4412 moves upward, then passes through the filter screen positioning groove 02 on both sides of the limiting groove, and pushes the two ends of the filter screen upward, thus pushing the filter screen from a flat state to a U-shaped state, so that the filter screen wraps and fits snugly around the bottom of the valve sleeve.

[0093] Furthermore, such as Figure 13 As shown, the side filter screen pushing device 442 includes a linear pushing cylinder 4421 and a side pushing block 4422. The linear pushing cylinder 4421 is arranged on both sides of the valve sleeve positioning groove 01 in a direction perpendicular to the valve sleeve axis. The push rod end of the linear pushing cylinder 4421 is provided with a side pushing block 4422. A side pushing protrusion is provided on one side of the side pushing block at the position corresponding to the filter screen positioning groove 02.

[0094] The linear push cylinders 4421 located on both sides of the valve sleeve positioning groove 01 extend towards each other, thereby driving the side push blocks 4422 on both sides to move closer to each other. The side push blocks 4422 on both sides push the two sides of the U-shaped filter screen, thereby making the filter screen wrap around and fit against the outside of the valve sleeve along the circumference.

[0095] Furthermore, such as Figure 14 As shown, the stepping valve sleeve transplanting device 43 includes a stepping translation device 431, a proximity translation device 432, a valve sleeve lifting device 433, and a valve sleeve pneumatic clamp 434. The stepping translation device 431 moves parallel to the axial direction of the valve sleeve. The translation part of the stepping translation device 431 is provided with a proximity translation device 432 that moves perpendicular to the axial direction of the valve sleeve. The translation part of the proximity translation device 432 is provided with a valve sleeve lifting device 433 that moves in the vertical direction. The lifting part of the valve sleeve lifting device 433 is provided with a valve sleeve pneumatic clamp 434 corresponding to the valve sleeve positioning groove.

[0096] The stepping translation device 431 enables stepping movement between different workstations. The movement of the approach translation device 432, in conjunction with the lifting of the valve sleeve lifting device 433, drives the valve sleeve pneumatic clamp 434 to approach the valve sleeve positioning groove 01. The stepping translation device 431 is a screw translation assembly, with an adapter seat on its translation section. The approach translation device 432 includes several linearly arranged slide rails on the adapter seat, a slider slidably arranged on the slide rails, and a linear push cylinder connected to and driving the slider to slide. A lifting device is provided on the other side of the slider. The valve sleeve lifting device 433 includes a lifting cylinder and an adapter seat connected to the push rod of the lifting cylinder. The valve sleeve pneumatic clamp is provided on the adapter seat.

[0097] Furthermore, such as Figure 15 As shown, the filter screen pickup device 42 includes a filter screen translation device 421, a filter screen lifting device 422, and a filter screen adsorption device 423. The filter screen translation device 421 moves linearly perpendicular to the valve sleeve's axial direction, corresponding to the valve sleeve positioning groove 01. The filter screen lifting device 422 is mounted on the translation part of the filter screen translation device 421, and the filter screen adsorption device is mounted on the lifting part of the filter screen lifting device 422. Through the translation of the filter screen translation device 421 and the lifting of the filter screen lifting device 422, the filter screen adsorption device 423 is driven to approach the filter screen and adsorb it, then moves it to the filter screen positioning groove 02 for placement. The filter screen translation device 421 includes a screw linear translation device. The translation part of the screw linear translation device is provided with a filter screen lifting device. The filter screen lifting device 422 includes a lifting cylinder and a transition seat connected to the push rod end of the lifting cylinder. The transition seat is provided with a filter screen adsorption device. The filter screen adsorption device 423 consists of several pneumatic suction cups provided on the transition seat.

[0098] Furthermore, the loading end of the welding platform 41 is provided with a valve sleeve picking device for picking up the valve sleeve and placing the valve sleeve inside the valve sleeve positioning groove 01.

[0099] Furthermore, the valve sleeve picking device includes a three-axis moving device, a rotating device is provided on the moving part of the three-axis moving device, and a valve sleeve clamp is provided on the rotating end of the rotating device.

[0100] The three-axis moving device includes an X-axis translation device that moves parallel to the valve sleeve positioning groove 01, a Y-axis translation device that moves perpendicular to the valve sleeve positioning groove 01, and a Z-axis lifting device that moves vertically. Through the coordinated movement of the three-axis moving device in these three directions, the valve sleeve clamp picks up the valve sleeve from the loading area. Simultaneously, an optional device rotates the valve sleeve clamp, thereby changing the orientation of the valve sleeve.

[0101] Furthermore, such as Figure 16As shown, the mobile welding device 45 includes a first translation device 451, a second translation device 452, a welding lifting device 453, and a welding device 454. The first translation device 451 moves parallel to the direction of the filter screen positioning groove 02. The second translation device 452 is provided on the translation part of the first translation device 451. The second translation device 452 moves parallel to the direction of the valve sleeve positioning groove 01. The welding lifting device 453 is provided on the translation part of the second translation device 452. The welding device 454 is provided on the lifting part of the welding lifting device 453.

[0102] The first translation device 451 moves linearly in a direction perpendicular to the valve sleeve positioning groove 01, the second translation device 452 moves linearly in a direction parallel to the valve sleeve positioning groove 01, and the welding lifting device 453 moves up and down in a vertical direction, thereby driving the welding device 453 to approach the top of the valve sleeve, and then the welding device 454 welds the seam of the filter screen on the outside of the valve sleeve.

[0103] The other parts of this embodiment are the same as any one of the embodiments 1-3 above, so they will not be described again.

[0104] Example 5:

[0105] This embodiment is a further optimization based on any one of embodiments 1-4 above, such as... Figure 20 As shown, the valve body and valve sleeve assembly device 5 includes a valve sleeve transmission device 51, a valve body transmission device 52, a valve sleeve and valve body assembly and transfer device 53, and a fastening and sealing device 54. The valve sleeve transmission device 51 transmits the valve sleeve to the feed end of the valve sleeve and valve body assembly and transfer device 53, and the valve body transmission device 52 transmits the valve body to the feed end of the valve sleeve and valve body assembly and transfer device 53. The valve sleeve and valve body assembly and transfer device 53 assembles the valve body and valve sleeve at the feed end and transfers the assembled parts to the feed end of the fastening and sealing device 54.

[0106] Furthermore, such as Figure 21 As shown, the fastening and sealing device 54 includes a linear transfer device 541, and a closing device 542, a riveting device 543, and a sealing device 544 arranged along the transmission direction of the linear transfer device 541. The linear transfer device 541 picks up the assembly from the valve sleeve and valve body assembly transfer device 53 and sequentially transfers the assembly to the closing device 542, the riveting device 543, and the sealing device 544 to sequentially close, rivet, and seal the assembly.

[0107] The valve sleeve conveying device 51 is a belt conveyor line, on which several valve sleeve carriers for positioning valve sleeves are linearly arranged. The belt conveyor line drives several valve sleeves to move to the loading end of the valve sleeve and valve body assembly and transfer device 53. The valve body conveying device 52 is a belt conveyor line, on which several valve body carriers for positioning valve bodies are linearly arranged. The belt conveyor line drives several valve bodies to move to the loading end of the valve sleeve and valve body assembly and transfer device 53.

[0108] The valve sleeve and valve body assembly and transfer device 53 has an assembly seat at its feed end, with several assembly stations and valve sleeve positioning seats at each station. The valve sleeve and valve body assembly and transfer device 53 first picks up the valve sleeve from the valve sleeve transfer device 51 and transfers it to the valve sleeve positioning seat for positioning. Then, the valve sleeve and valve body assembly and transfer device 53 picks up the valve body from the valve body transfer device 52 and transfers it to the outside of the valve sleeve, thus completing the assembly of the valve body and valve sleeve. The assembly is then moved by the valve sleeve and valve body assembly and transfer device 53 to the feed end of the linear transfer device 541 in the fastening and sealing device 54. After the linear transfer device 541 picks up the assembly, it moves the assembly sequentially to the closing device 542, the riveting device 543, and the sealing ring device 544.

[0109] Each station corresponding to the closing device 542, riveting device 543, and sealing device 544 is equipped with a carrier for positioning the assembled parts. The assembled parts are placed on the carrier by the linear transfer device 541, and then the closing device 542, riveting device 543, and sealing device 544 sequentially perform the closing, riveting, and sealing ring installation operations on the assembled parts. After the assembly is tightened and sealed, it is moved by the linear transfer device 41 to the finished product box at the discharge end for storage.

[0110] Furthermore, the valve sleeve transmission device 51 and the valve body transmission device 52 are arranged perpendicular to each other in the transmission direction. The valve sleeve and valve body assembly and transfer device 53 includes a first translation device parallel to the valve body transmission device 52 and a second translation device parallel to the valve sleeve transmission device 51. A first lifting device and a second translation device are respectively arranged on both sides of the translation part of the first translation device. A second lifting device is arranged on the translation part of the second translation device. A first pneumatic clamp is arranged on the lifting part of the first lifting device, and a second pneumatic clamp is arranged on the lifting part of the second lifting device.

[0111] The second translation device drives the second lifting device to move linearly between the discharge end of the valve sleeve transmission device 51 and the assembly seat, parallel to the transmission direction of the valve sleeve transmission device 51. The second lifting device drives the second pneumatic clamp to rise and fall, thereby enabling the second pneumatic clamp to pick up the valve sleeve from the discharge end of the valve sleeve transmission device 51 and install it on the assembly seat. The first translation device drives the first lifting device to move linearly between the discharge end of the valve shell transmission device 52 and the assembly seat, parallel to the transmission direction of the valve shell transmission device 52. The first lifting device drives the first pneumatic clamp to rise and fall, enabling the first pneumatic clamp to pick up the valve shell from the discharge end of the valve shell transmission device 52 and transfer it to the assembly seat, and then fit the valve shell onto the outside of the valve sleeve.

[0112] Furthermore, such as Figure 20 As shown, the discharge end of the valve housing conveying device 52 is equipped with a valve housing flipping device 55, which flips the valve housing and transfers it to the valve sleeve and valve housing assembly and transfer device 53.

[0113] When the valve body is installed onto the valve sleeve, there is an orientation requirement. Before assembling the valve body and the valve sleeve, the valve body is picked up in advance by the valve body flipping device 55 and rotated 180° to change the orientation of the valve body.

[0114] Furthermore, the valve housing flipping device 55 includes a screw linear translation device arranged parallel to the transmission direction of the valve housing transmission device 52. A vertical lifting device is provided on the translation part of the screw linear translation device, and a rotary cylinder is provided on the lifting part of the vertical lifting device. A gripper for holding the valve housing is provided on the rotating part of the rotary cylinder.

[0115] The closing device 542 includes a closing punch, a closing clamp, and a closing correction device. The closing punch and the closing correction device are coaxially arranged. The closing clamp is provided on the punching end of the closing punch. After the linear transfer device 541 positions the assembly on the closing correction device, it closes the assembly by means of the closing clamp.

[0116] A closing positioning seat for positioning the assembly is provided between the stamping end of the stamping press and the closing correction device. The closing positioning seat has a positioning hole for positioning the assembly. The stamping end of the stamping press is coaxially positioned at the top of the positioning hole, and the closing correction device is coaxially positioned at the bottom of the positioning hole. The assembly is picked up and installed in the positioning hole by the linear transfer device 541. Then, the stamping press drives the closing fixture to press down, so that the closing flange on the closing fixture contacts and squeezes the closing edge on the assembly, thereby closing the assembly. At the same time, during the closing process, the bottom of the assembly is positioned and calibrated by the closing correction device located at the bottom of the positioning hole, thereby ensuring the closing quality.

[0117] Furthermore, the closing correction device includes a closing positioning seat, a closing lifting cylinder, and a closing positioning probe. The closing positioning seat is coaxially arranged with respect to the closing punching machine. The closing positioning seat is provided with a correction hole. The closing positioning probe is axially slidably arranged in the correction hole. The bottom of the closing positioning probe is connected to the closing lifting cylinder.

[0118] The alignment hole on the closing positioning seat mates with the outer surface of the bottom of the assembly, thereby achieving the alignment and positioning of the assembly and ensuring that the assembly and the stamping machine remain strictly coaxial. During the stamping closing process, the closing positioning probe is extended upward by the closing lifting cylinder, so that the top of the closing positioning probe contacts the bottom positioning end face of the assembly. At this time, the controller connected to the closing positioning probe sends a signal to the stamping machine, causing the stamping machine to stop moving downward and stamping, thus avoiding damage to the assembly.

[0119] Furthermore, the riveting device 543 includes a riveting positioning seat and a riveting pushing device. The linear transfer device 541 places the assembly on the riveting positioning seat for fixed positioning. The riveting pushing device is arranged circumferentially on the outside of the riveting positioning seat, and a riveting head is provided on the pushing end of the riveting pushing device. The riveting positioning seat is provided with positioning holes for installing and positioning the assembly. The linear transfer device 541 picks up the assembly and installs it in the positioning holes to axially position the assembly. After the assembly is positioned, the pushing end of the riveting pushing device corresponds exactly to the circumferential riveting edge of the assembly. At this time, the riveting pushing device drives the riveting head to extend towards the assembly, thereby pressing the riveting edge of the assembly through the riveting head, thus realizing the riveting of the assembly.

[0120] Furthermore, a suction cup is provided at the bottom of the positioning hole, and an air suction device is provided at the bottom of the suction cup. Air is drawn in by the air suction device, thereby forming an airflow from top to bottom inside the assembly, which blows out the debris in the assembly.

[0121] Furthermore, the sealing ring device 544 includes a sealing ring positioning seat, an inner sealing ring expansion clamp, and an outer sealing ring positioning clamp. The linear transplanting device 541 places the assembly on the sealing ring positioning seat for fixed positioning. The inner sealing ring expansion clamp and the outer sealing ring positioning clamp are coaxially arranged on the top of the sealing ring positioning seat. The inner sealing ring expansion clamp clamps the inner side of the sealing ring, and the outer sealing ring positioning clamp clamps the outer side of the sealing ring corresponding to the sealing ring installation position on the assembly. The clamping surface of the outer sealing ring positioning clamp is provided with a positioning part for positioning the sealing ring corresponding to the sealing ring installation position on the assembly. The inner sealing ring expansion clamp includes a translation device, a lifting device, and several inner expansion clamps that are evenly distributed circumferentially and can expand or contract synchronously. The translation part of the translation device is provided with a lifting device, and the lifting part of the lifting device is evenly distributed circumferentially with several inner expansion clamps that can expand or contract synchronously. The translation and lifting mechanisms work together to allow the internal expansion chucks to pick up the sealing ring and move it to the top of the assembly. The space between the internal expansion chucks accommodates the assembly, preventing interference when the lifting mechanism lowers the chucks. When the internal expansion chucks expand synchronously, they tighten the inner ring of the sealing ring to clamp it. The lifting mechanism then lowers the chucks, positioning the sealing ring on the outside of the assembly. An external positioning fixture then positions the sealing ring, preventing it from moving vertically with the joint. The lifting mechanism then raises the internal expansion chucks, disengaging them from the inner ring of the sealing ring. The external positioning fixture maintains the outer edge of the sealing ring, ensuring its relative position to the assembly remains unchanged. Once the internal expansion fixtures are completely disengaged from the inner ring, the sealing ring contracts under its own elasticity, fitting onto the outside of the assembly, thus completing the installation.

[0122] Furthermore, the positioning part includes a positioning groove provided on the clamping surface of the positioning fixture outside the sealing ring. The outer ring surface of the sealing ring is clamped by the positioning groove, thereby axially positioning the sealing ring so that the relative position between the sealing ring and the assembly does not change.

[0123] Furthermore, such as Figure 21As shown, the discharge end of the linear transplanting device 541 is also equipped with a sealing detection device 545. The sealing detection device 545 includes a detection positioning seat, a bottom sealing device, and a top sealing device. The detection positioning seat has a positioning hole for positioning the assembly. A top sealing device for sealing the top of the assembly is coaxially disposed at the top of the positioning hole, and the top of the top sealing device has an air inlet. A bottom sealing device for sealing the bottom of the assembly is coaxially disposed at the bottom of the positioning hole. The top sealing device includes a top sealing tube with an air inlet connected to an external air pipe. The top sealing tube is directly fitted onto the top of the assembly to seal the top of the assembly. The bottom sealing device includes a sealing suction cup disposed at the bottom of the positioning hole, which seals the bottom of the assembly. Air is then introduced through the air inlet to detect whether there is any leakage in the assembly.

[0124] The other parts of this embodiment are the same as any one of the embodiments 1-4 above, so they will not be described again.

[0125] Example 6:

[0126] This embodiment is a further optimization based on any one of embodiments 1-5 above, such as... Figure 22 As shown, the magnetic tube valve housing assembly device 1 includes a rotating platform, a picking robot 11, a magnetic tube carrier 12, a valve housing pressing device 13, and a single-axis unloading device 14. The picking robot 11, valve housing pressing device 13, and single-axis unloading device 14 are sequentially arranged around the rotating platform along the rotation direction. Several magnetic tube carriers 12 are arranged circumferentially on the top of the rotating platform. The magnetic tube carriers 12 pass sequentially through the picking robot 11, valve housing pressing device 13, and single-axis unloading device 14 as the rotating platform rotates. The picking robot 11 first picks up the magnetic tube and places it on the magnetic tube carrier 12. Then, the picking robot 11 picks up the valve housing and fits it onto the magnetic tube. The valve housing pressing device 13 is used for vertically pressing and assembling the magnetic tube and valve housing. The single-axis unloading device 14 is used to pick up the valve housing and transport it to the feed end of the first assembly transport line 001.

[0127] One side of the rotating platform is equipped with a magnetic tube tray for holding magnetic tubes and a valve housing tray for holding valve housings. The picking robot 11 first picks up a magnetic tube from the magnetic tube tray and positions it on the magnetic tube carrier 12. Then, the picking robot 11 picks up a valve housing from the valve housing tray and fits it onto the outside of the magnetic tube. The rotation of the rotating platform then drives the magnetic tube and valve housing to the valve housing pressing device 13, where the pressing device 13 presses down to assemble the valve housing and magnetic tube. The rotating platform then drives the assembled magnetic tube and valve housing to the unloading station, where a single-axis unloading device 14 picks up the assembled product and transfers it to the feeding end of the first assembly transport line 001.

[0128] Furthermore, the single-axis unloading device 14 includes a single-axis linear translation device and a pneumatic gripper disposed on the translation part of the single-axis linear translation device. The single-axis linear translation device drives the pneumatic gripper to move between the unloading station and the feeding end of the first assembly transport line 001, and the pneumatic gripper picks up the assembly parts of the magnetic tube and the valve body.

[0129] Furthermore, such as Figure 23 As shown, the first assembly transport line 001 includes a first linear transport line 001a and a magnetic core assembly device 001b mounted across the top of the first linear transport line 001a. The feed end of the first linear transport line 001a is connected to the discharge end of the magnetic tube valve housing assembly device 1, and the discharge end of the first linear transport line 001a is connected to the feed end of the valve housing internals assembly device 3. The magnetic core assembly device 001b is used to pick up the magnetic core at the discharge end of the magnetic core assembly device 2, and then transfer the magnetic core to the top of the first linear transport line 001a and assemble it into the valve housing.

[0130] Furthermore, the first assembly transport line 001 includes a transport belt and several assembly carriers linearly arranged on the transport belt; the magnetic core assembly device 001b includes a magnetic core assembly translation device and assembly grippers arranged on the translation part of the magnetic core assembly translation device. The single-axis unloading device 14 clamps the assembled magnetic tube and valve body and places them on the assembly carriers on the transport belt for positioning. When the assembly carrier passes the magnetic core assembly device 001b, the assembly grippers pick up the magnetic core from the discharge end of the magnetic core assembly device 2, and then translate to assemble the magnetic core inside the magnetic tube.

[0131] The other parts of this embodiment are the same as any one of the embodiments 1-5 above, so they will not be described again.

[0132] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
