Description

Technical Field

[0001] The present application relates to the technical field of inductor production, and particularly to a stacked inductor and its assembling process. Background Art

[0002] A stacked inductor is an inductor, and its structural feature lies in that the inductor coil is designed in a multi-layer stacked form. This design can make more effective use of space, especially in occasions where a high inductance value is required but the space is limited. A stacked inductor usually consists of an inductor core, a conductive unit formed by a bottom half coil, a conductive unit formed by a top half coil, a circuit substrate, and other parts. These parts are combined together through specific connection methods and sealing processes to form a complete inductor.

[0003] Since a stacked inductor coil is composed of multiple groups of coils, a stacked inductor usually has multiple groups of pins. The appearance of multiple groups of pins during welding will increase the welding difficulty for workers. Therefore, there is a need for a stacked inductor and its assembling process that can solve the welding of multiple groups of pins. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present application is a stacked inductor and its assembling process for solving the above technical problems.

[0005] The above purpose of the present application is achieved through the following technical solutions: An assembling process for a stacked inductor, comprising the following steps:

[0006] S1. Place the pins on the conveying device respectively;

[0007] S2. Place the solder bar coil on the placement shaft on the vertical plate;

[0008] S3. Place multiple groups of inductor housings in the placement frame; start the conveying belt, and the pins move forward as the belt moves. When a group of pins reaches below the placement frame, the lowermost inductor housing in the placement frame drops onto this group of pins. As the belt continues to move, subsequent pins will also successively receive inductor housings;

[0009] S4. Start the placement motor to drive the first conveying shaft to rotate. Due to the meshing of the first ratchet and the second ratchet, the second conveying shaft also rotates accordingly. The two conveying shafts jointly squeeze the solder bar to make it move along a predetermined path;

[0010] S5. After being squeezed between the first conveying shaft and the second conveying shaft, the solder bar is conveyed to the welding position between the inductor housing and the pins;

[0011] S6. When the inductor housing and pins move to below the squeezing device along with the conveyor belt, start the squeezing cylinder, and the squeezing plate moves downward. Through the supporting force provided by the abutting plate, firmly fix the inductor housing;

[0012] S7. At the same time, start the pushing cylinder, and the front end of the soldering gun abuts against the solder bar that has moved into position;

[0013] S8. Start the linkage motor, drive the first cutting shaft and the second cutting shaft to rotate. The first blade and the second blade cut each other to cut off the solder bar, and the soldering gun immediately heats the cut solder bar to melt it and weld the inductor housing and the pins;

[0014] S9. After welding is completed, as the conveyor belt continues to move, the inductor housing and pins that have been welded are transported to the next process.

[0015] By adopting the above technical solution, the pins are respectively placed in the respective placement slots on the transport conveyor belt to ensure the stability of the pins during the conveying process. Then, place the solder bar coil on the placement shaft on the vertical plate to ensure that the solder bar coil is firmly fixed. Then, neatly place multiple groups of inductor housings in the placement frame and start the transport conveyor belt. The pins move forward along with the movement of the conveyor belt. When a group of pins reaches below the placement frame, due to the action of gravity, the lowermost inductor housing in the placement frame automatically drops onto this group of pins. As the conveyor belt continues to move, subsequent pins will also successively receive the inductor housing.

[0016] At this time, start the placement motor, and this motor drives the first transport shaft to start rotating. Due to the tight meshing of the first ratchet and the second ratchet, the second transport shaft also rotates synchronously. The two transport shafts jointly squeeze the solder bar to make it move forward stably along the predetermined path to prepare for the subsequent welding work. After being squeezed between the first transport shaft and the second transport shaft, the solder bar is accurately transported to the welding position between the inductor housing and the pins.

[0017] When the inductor housing and pins move to below the squeezing device along with the conveyor belt, start the squeezing cylinder. The output end of the squeezing cylinder pushes the squeezing plate downward, and through the stable supporting force provided by the abutting plate, firmly fix the inductor housing. At the same time, start the pushing cylinder, and the front end of the soldering gun accurately abuts against the solder bar that has moved into position under the push of the cylinder. At this time, the soldering gun is already in a state of waiting to be heated.

[0018] Then, start the linkage motor to drive the first cutting shaft and the second cutting shaft to start rotating. The first blade and the second blade cut each other under the drive of the motor to accurately cut off the solder bar. At the same time, the soldering gun immediately heats the cut solder bar to quickly melt it and firmly weld the inductor housing and the pins.

[0019] After welding is completed, as the conveyor belt continues to move, the welded inductor housing and pins are automatically transported to the next process for subsequent processing. During the entire use process, each component works together to ensure the automation, efficiency, and accuracy of the welding process. The operator only needs to perform simple placement, startup, and monitoring operations to achieve rapid welding of the inductor housing and pins.

[0020] Furthermore, the transportation device includes a base plate, and a through groove is provided on the base plate. A transportation conveyor belt for transporting pins is arranged in the through groove. Multiple placement grooves for placing pins are provided on the transportation conveyor belt. A placement device for placing the inductor housing is arranged at the upper end of the transportation conveyor belt. Solder structures for adjusting the soldering of the pins to the inductor housing are arranged on both sides of the transportation conveyor belt.

[0021] By adopting the above technical solution, when soldering the pins to the inductor, the pins are placed in multiple placement grooves on the transportation conveyor belt, and then moved by the transportation conveyor belt. At this time, the placement device will place the inductor housing on top of multiple groups of pins, and then fix it by soldering through the solder structures on both sides.

[0022] Furthermore, the placement device includes support plates fixedly connected to both sides of the base plate. A placement frame is fixedly arranged in the middle of the two support plates. Multiple groups of inductor housings are placed in the placement frame.

[0023] By adopting the above technical solution, the inductor housings in the placement frame will directly fall onto the pins on the transportation conveyor belt. After one inductor housing falls onto a group of pins, as the transportation conveyor belt transports, the lowermost inductor housing in the placement frame will continue to fall onto the transportation conveyor belt.

[0024] Furthermore, the solder structure includes a vertical plate on one side of the transportation conveyor belt. A push cylinder is installed on the vertical plate. A soldering gun is fixedly arranged at the output end of the push cylinder. The soldering head of the soldering gun is in a long strip shape. An extrusion device for extruding and fixing the inductor housing is arranged on one side of the placement frame.

[0025] By adopting the above technical solution, when the transportation conveyor belt transports the inductor housing and pins to the extrusion device, it will fix the upper inductor housing, and then fix it by soldering between the pins and the inductor housing through the soldering gun on the push cylinder.

[0026] Further, a transport assembly for placing solder bars is also provided on the vertical plate. The transport assembly includes a placement shaft rotatably connected to the vertical plate. On one side of the placement shaft, there is a transport plate fixedly connected to the vertical plate. On the transport plate, a first transport shaft and a second transport shaft are rotatably arranged. On the ends of the first transport shaft and the second transport shaft away from the transport plate, there is a mounting plate. The mounting plate is rotatably connected to the first transport shaft and the second transport shaft. A first ratchet is fixedly arranged on the first transport shaft, and a second ratchet meshing with the first ratchet is fixedly arranged on the second transport shaft. The first transport shaft passes through the mounting plate, and a placement motor is fixedly arranged on the mounting plate. The output end of the placement motor is fixedly connected to the first transport shaft. A cutting device for cutting the solder bar is arranged on the mounting plate.

[0027] By adopting the above technical solution, place the solder bar roll on the placement shaft, then pull the solder bar and place it between the first transport shaft and the second transport shaft. Drive the first transport shaft to rotate through the placement motor, and at the same time drive the second transport shaft by meshing the first ratchet with the second ratchet, thereby squeezing and driving the solder bar to move onto the conveyor belt, and then it will reach between the inductor housing and the pin, be cut by the cutting device, and then be welded and fixed by a soldering gun.

[0028] Further, the cutting device includes a linkage rod fixedly connected to the output end of the pushing cylinder. At the end of the linkage rod, there is a linkage plate fixedly arranged. On the linkage plate, a first cutting shaft and a second cutting shaft are rotatably arranged. A first blade is fixedly arranged on the first cutting shaft, and a second blade is fixedly arranged on the second cutting shaft. The first blade and the second blade are mutually attached. A first linkage ratchet is fixedly arranged on the first cutting shaft, and a second linkage ratchet meshing with the first linkage ratchet is fixedly arranged on the second cutting shaft. A linkage motor is fixedly arranged on the linkage plate, and the output end of the linkage motor is fixedly connected to the first cutting shaft.

[0029] By adopting the above technical solution, when the solder bar is squeezed between the inductor housing and the pin by the first transport shaft and the second transport shaft, the output end of the pushing cylinder pushes, driving the front end of the soldering gun to abut against the solder bar. At the same time, the linkage rod pushes, and the linkage motor drives the first blade and the second blade to rotate to cut the solder bar, and then the soldering gun immediately completes the soldering and fixing.

[0030] Further, the pressing device includes a placement plate fixedly connected to the placement frame. At the bottom of the placement plate, there is a pressing cylinder fixedly arranged. On the output end of the pressing cylinder, there is a pressing flat plate. A secondary pressing structure is arranged on the pressing flat plate and the output end of the pressing cylinder. In the middle of the transport conveyor belt, there is an abutting plate fixedly connected to the base plate. When the pressing flat plate presses down to fix the inductor housing, the abutting plate provides support force for the inductor housing through its setting.

[0031] By adopting the above technical solution, after the transport conveyor belt transports the inductor housing to the extrusion cylinder, the extrusion cylinder is started to move the extrusion flat plate

[0032] Furthermore, a pair of rotating plates are fixedly arranged on one side of the vertical plate. A rotating shaft is rotatably arranged on the rotating plate. The rotating shaft is fixedly connected to the pushing cylinder. A rotating motor is fixedly connected to the outside of the rotating plate. The output end of the rotating motor is fixedly connected to the rotating shaft.

[0033] By adopting the above technical solution, through the setting of the rotating motor, the pushing angle of the pushing cylinder can be changed.

[0034] Furthermore, the secondary extrusion structure includes an upper extrusion plate fixedly installed at the output end of the extrusion cylinder. Upper adjusting plates are rotatably arranged on both sides of the upper extrusion plate. An extrusion vertical rod is rotatably arranged at one end of the upper adjusting plate far away from the upper extrusion plate. Lower adjusting plates are rotatably arranged at the bottoms of the two extrusion vertical rods. A lower extrusion plate is rotatably arranged between the bottoms of the two extrusion vertical rods. The bottom of the lower extrusion plate is fixedly connected to the extrusion flat plate. An extrusion spring is fixedly arranged between the upper extrusion plate and the lower extrusion plate.

[0035] By adopting the above technical solution, when the output end of the extrusion cylinder presses down, it drives the upper extrusion plate to press down. When the extrusion flat plate on the lower extrusion plate abuts against the upper end of the inductor housing, it will continue to press down. The upper adjusting plates and the lower adjusting plates on both sides will continue to rotate along with the extrusion vertical rods, and an additional extrusion force is applied through the extrusion of the extrusion spring.

[0036] Furthermore, an assembling process for a stacked inductor is applicable to any one of the above technical solutions for a stacked inductor, including an inductor housing. A plurality of groups of pins are fixedly arranged at the bottom of the inductor housing. A magnetic core is fixedly arranged between each pair of pins. A plurality of groups of inductor coils are fixedly wound on the magnetic core. A separating component for separating each group of pins is arranged in the inductor housing. The separating component includes a cross plate and a top plate fixedly connected to the upper end of the cross plate. The top plate is fixedly connected to the inductor housing.

[0037] By adopting the above technical solution, through the setting of the cross plate, the magnetic cores and inductor coils on each group of pins are separated, avoiding the problem of mutual interference between inductors. At the same time, the upper end of the inductor housing can be closed by the top plate.

[0038] In summary, the present application includes the following beneficial technical effects: Through the coordinated operation of automated components such as a transportation conveyor belt, a placement device, a soldering structure, and an extrusion device, the rapid and accurate soldering of the inductor housing and pins is achieved. Compared with traditional manual soldering, the production efficiency is greatly improved, and the labor cost is reduced. The soldering gun in the soldering structure is precisely coordinated with the cutting device, and can quickly cut the solder strip and perform soldering when the inductor housing and pins reach the designated positions, ensuring the accuracy and stability of soldering. At the same time, the setting of the pushing cylinder and the rotating motor enables the soldering gun to perform soldering at different angles, adapting to inductor housings of different shapes and sizes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] The following further elaborates on the present application with reference to the accompanying drawings.

[0046] Embodiment, referring to Figure 1 - Figure 4, An assembly process for a stacked inductor, comprising the following steps:

[0047] S1. Place the pins 61 on the transport device respectively;

[0048] S2. Place the solder bar coil on the placement shaft 23 on the vertical plate 22;

[0049] S3. Place multiple groups of inductor housings 6 in the placement frame 12; Start the transport conveyor belt 2, and the pins 61 move forward as the conveyor belt moves. When a group of pins 61 reaches below the placement frame 12, the lowermost inductor housing 6 in the placement frame 12 drops onto this group of pins 61. As the conveyor belt continues to move, subsequent pins 61 will also successively receive the inductor housings 6;

[0050] S4. Start the placement motor 20 to drive the first transport shaft 26 to rotate. Due to the meshing of the first ratchet 28 and the second ratchet 29, the second transport shaft 27 also rotates accordingly. The two transport shafts jointly squeeze the solder bar to make it move along a predetermined path;

[0051] S5. After the solder bar is squeezed between the first transport shaft 26 and the second transport shaft 27, it is conveyed to the welding position between the inductor housing 6 and the pins 61;

[0052] S6. When the inductor housing 6 and the pins 61 move to below the squeezing device along with the conveyor belt, start the squeezing cylinder 31, and the squeezing plate 38 moves downward. Through the supporting force provided by the abutting plate, the inductor housing 6 is firmly fixed;

[0053] S7. At the same time, start the pushing cylinder 41, and the front end of the soldering gun 42 abuts against the solder bar that has moved into place;

[0054] S8. Start the linkage motor 56 to drive the first cutting shaft 52 and the second cutting shaft 53 to rotate. The first blade 54 and the second blade 55 cut each other to cut off the solder bar. The soldering gun 42 immediately heats the cut solder bar to melt it and weld the inductor housing 6 and the pins 61;

[0055] S9. After welding is completed, as the conveyor belt continues to move, the welded inductor housing 6 and pins 61 are conveyed to the next process.

[0056] Place the pins 61 into the respective placement slots 21 on the transport conveyor belt 2, ensuring that the pins 61 remain stable during transportation. Then, place the solder bar roll on the placement shaft 23 on the vertical plate 22, ensuring that the solder bar roll is firmly fixed. Next, neatly place multiple groups of inductor housings 6 into the placement frame 12 and start the transport conveyor belt 2. The pins 61 move forward as the conveyor belt moves. When a group of pins 61 reaches below the placement frame 12, due to gravity, the lowermost inductor housing 6 in the placement frame 12 automatically drops onto this group of pins 61. As the conveyor belt continues to move, subsequent pins 61 will also successively receive inductor housings 6.

[0057] At this time, start the placement motor 20, and this motor drives the first transport shaft 26 to start rotating. Due to the tight meshing of the first ratchet 28 and the second ratchet 29, the second transport shaft 27 also rotates synchronously. The two transport shafts jointly squeeze the solder bar, making it move forward stably along a predetermined path, preparing for the subsequent soldering work. After being squeezed between the first transport shaft 26 and the second transport shaft 27, the solder bar is precisely conveyed to the soldering position between the inductor housing 6 and the pins 61.

[0058] When the inductor housing 6 and the pins 61 move to below the squeezing device along with the conveyor belt, start the squeezing cylinder 31. The output end of the squeezing cylinder 31 pushes the squeezing flat plate 38 downward, and through the stable supporting force provided by the abutting plate, firmly fixes the inductor housing 6. At the same time, start the pushing cylinder 41, and the front end of the soldering gun 42 precisely abuts against the solder bar that has moved into position under the push of the cylinder. At this time, the soldering gun 42 is already in a state of waiting to be heated.

[0059] Next, start the linkage motor 56, driving the first cutting shaft 52 and the second cutting shaft 53 to start rotating. The first blade 54 and the second blade 55 cut against each other under the drive of the motor, precisely cutting off the solder bar. At the same time, the soldering gun 42 immediately heats the cut solder bar, making it quickly melt and firmly solder the inductor housing 6 and the pins 61.

[0060] After soldering is completed, as the conveyor belt continues to move, the soldered inductor housing 6 and pins 61 are automatically conveyed to the next process for subsequent processing. During the entire use process, each component works together to ensure the automation, high efficiency, and accuracy of the soldering process. The operator only needs to perform simple placement, startup, and monitoring operations to achieve the rapid soldering of the inductor housing 6 and the pins 61.

A placement device for placing the inductor housing 6 is arranged above the transportation conveyor belt 2. Solder structures for adjusting the soldering of the pins 61 to the inductor housing 6 are arranged on both sides of the transportation conveyor belt 2. When soldering the pins 61 to the inductor, the pins 61 are placed in a plurality of placement grooves 21 on the transportation conveyor belt 2, and then moved by the transportation conveyor belt 2. At this time, the placement device will place the inductor housing 6 above a plurality of groups of pins 61, and then fix them by soldering through the solder structures on both sides.

[0062] In this embodiment, the placement device includes support plates 11 fixedly connected to both sides of the base plate 1. A placement frame 12 is fixedly arranged in the middle of the two support plates 11. A plurality of groups of inductor housings 6 are placed in the placement frame 12. The inductor housings 6 in the placement frame 12 will directly fall onto the pins 61 on the transportation conveyor belt 2. After one inductor housing 6 falls onto a group of pins 61, as the transportation conveyor belt 2 transports, the lowermost inductor housing 6 in the placement frame 12 will continue to fall onto the transportation conveyor belt 2.

[0063] In this embodiment, the solder structure includes a vertical plate 22 on one side of the transportation conveyor belt 2. A pushing cylinder 41 is installed on the vertical plate 22. A soldering gun 42 is fixedly arranged at the output end of the pushing cylinder 41. The soldering head of the soldering gun 42 is in a long strip shape. An extrusion device for extruding and fixing the inductor housing 6 is arranged on one side of the placement frame 12. When the transportation conveyor belt 2 transports the inductor housing 6 and the pins 61 to the extrusion device, it will fix the upper inductor housing 6, and then fix the pins 61 and the inductor housing 6 by soldering with the soldering gun 42 on the pushing cylinder 41.

[0065] Place the solder bar coil on the placement shaft 23, then pull the solder bar and place it between the first transport shaft 26 and the second transport shaft 27. Drive the first transport shaft 26 to rotate by the placement motor 20, and at the same time drive the second transport shaft 27 by engaging the first ratchet 28 with the second ratchet 29, thereby squeezing and driving the solder bar to move onto the conveyor belt. Then it will reach between the inductor housing 6 and the pin 61, be cut by the cutting device, and then be welded and fixed by the soldering gun 42.

[0066] In this embodiment, the cutting device includes a linkage rod 5 fixedly connected to the output end of the pushing cylinder 41. A linkage plate 51 is fixedly arranged at the end of the linkage rod 5. A first cutting shaft 52 and a second cutting shaft 53 are rotatably arranged on the linkage plate 51. A first blade 54 is fixedly arranged on the first cutting shaft 52, and a second blade 55 is fixedly arranged on the second cutting shaft 53. The first blade 54 and the second blade 55 are mutually attached.

When the solder bar is squeezed between the inductor housing 6 and the pin 61 by the first transport shaft 26 and the second transport shaft 27, the output end of the pushing cylinder 41 pushes, driving the front end of the soldering gun 42 to abut against the solder bar. At the same time, the linkage rod 5 pushes, and the starter of the linkage motor 56 drives the first blade 54 and the second blade 55 to rotate to cut the solder bar, and then the soldering gun 42 immediately completes the soldering and fixing.

[0067] In this embodiment, the squeezing device includes a placement plate 3 fixedly connected to the placement frame 12. A squeezing cylinder 31 is fixedly arranged at the bottom of the placement plate 3. An extrusion flat plate 38 is installed at the output end of the squeezing cylinder 31. A secondary extrusion structure is arranged on the extrusion flat plate 38 and the output end of the squeezing cylinder 31. A butting plate is arranged in the middle of the transport conveyor belt 2, and the butting plate is fixedly connected to the base plate 1. When the extrusion flat plate 38 squeezes and fixes the inductor housing 6 downward, the butting plate provides a supporting force for the inductor housing 6. When the transport conveyor belt 2 transports the inductor housing 6 to the squeezing cylinder 31, start the squeezing cylinder 31 to move the extrusion flat plate 38

[0068] In this embodiment, a pair of rotating plates 4 are fixedly arranged on one side of the vertical plate 22.

The bottom of the lower extrusion plate 36 is fixedly connected to the extrusion flat plate 38. An extrusion spring 37 is fixedly arranged between the upper extrusion plate 32 and the lower extrusion plate 36. When the output end of the extrusion cylinder 31 presses down, it drives the upper extrusion plate 32 to press down. When the extrusion flat plate 38 on the lower extrusion plate 36 abuts against the upper end of the inductor housing 6, it will continue to press down. The upper adjusting plates 33 and the lower adjusting plates 35 on both sides will continue to rotate along with the extrusion vertical rod 34, and an additional extrusion force is applied through the extrusion of the extrusion spring 37.

[0070] Referring to Figure 5 , an assembling process for a stacked inductor is applicable to any one of the above technical solutions for a stacked inductor, including an inductor housing 6. A plurality of groups of pins 61 are fixedly arranged on the outer side of the inductor housing 6. A magnetic core 62 is fixedly arranged between each pair of pins 61. A plurality of groups of inductor coils 63 are fixedly wound on the magnetic core 62. A separating component for separating each group of pins 61 is arranged in the inductor housing 6. The separating component includes a cross plate 65 and a top plate 64 fixedly connected to the upper end of the cross plate 65.

[0071] Through the arrangement of the cross plate 65, the magnetic cores 62 and the inductor coils 63 on each group of pins 61 are separated, avoiding the problem of mutual interference between inductors. At the same time, the upper end of the inductor housing 6 can be closed by the top plate 64.

[0072] Specific implementation process: First, the operator places the pins 61 in a plurality of placement slots 21 on the transport conveyor belt 2 respectively. Through its movement mechanism, the transport conveyor belt 2 transports the pins 61 one by one to the subsequent processing positions. At the same time, the solder bar roll is placed on the placement shaft 23 on the vertical plate 22 to ensure that the solder bar can be smoothly unwound and supplied during the welding process.

[0073] Then, a plurality of groups of inductor housings 6 are neatly placed in the placement frame 12. As the transport conveyor belt 2 continues to move, when a group of pins 61 reaches directly below the placement frame 12, due to gravity, the lowermost inductor housing 6 in the placement frame 12 will automatically fall onto this group of pins 61. As the conveyor belt moves further, the subsequent pins 61 will also successively receive the inductor housings 6, realizing the preliminary pairing of the inductor housings 6 and the pins 61.

[0074] At this time, the solder structure starts to play its role. The placement motor 20 starts, driving the first transport shaft 26 to start rotating. Due to the tight meshing of the first ratchet 28 and the second ratchet 29, the second transport shaft 27 also rotates synchronously. The two transport shafts jointly squeeze the solder strip, making it move steadily forward along a predetermined path until it reaches the welding position between the inductor housing 6 and the pin 61.

[0075] When the inductor housing 6 and the pin 61 move to below the squeezing device along with the conveyor belt, the squeezing cylinder 31 starts. The output end of the squeezing cylinder 31 pushes the squeezing plate 38 downward, and firmly fixes the inductor housing 6 through the stable supporting force provided by the abutting plate. This step ensures the stability of the inductor housing 6 during the welding process, avoiding poor welding caused by movement or vibration.

[0076] Meanwhile, the pushing cylinder 41 also starts. The front end of the soldering gun 42 precisely abuts against the solder strip that has moved into place under the push of the cylinder. At this time, the linkage motor 56 starts, driving the first cutting shaft 52 and the second cutting shaft 53 to start rotating. The first blade 54 and the second blade 55 cut against each other under the drive of the motor, precisely cutting off the solder strip. The cut solder strip is immediately heated and melted by the soldering gun 42, and quickly fills the gap between the inductor housing 6 and the pin 61, achieving a firm welded connection.

[0077] During the welding process, the secondary squeezing structure also plays an important role. When the squeezing plate 38 abuts against the upper end of the inductor housing 6, the squeezing spring 37 between the upper squeezing plate 32 and the lower squeezing plate 36 starts to play its role, providing an additional squeezing force to ensure the tightness and firmness of the welded joint.

[0078] In addition, through the setting of the rotating motor 40, the operator can flexibly adjust the pushing angle of the pushing cylinder 41 to adapt to inductor housings 6 and pins 61 of different sizes and shapes. This function increases the versatility and flexibility of the device.

[0079] Finally, after the welding is completed, as the conveyor belt continues to move, the welded inductor housing 6 and the pin 61 are automatically transported to the next process for subsequent processing. The entire welding process realizes automation, high efficiency, and precision, greatly improving the production efficiency and product quality.

[0080] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
