Technical Field

[0001] This invention relates to the technical field of common mode inductor manufacturing processes, and particularly to a common mode inductor manufacturing equipment and method. Background Technology

[0002] When producing common mode inductors, the enameled wire needs to be wound. Then, a series of processing steps are performed on both ends of the enameled wire, such as wire cutting, stripping, tubing, hot soldering, testing, sleeve, assembly, glue application, lead cutting, and hot soldering again. Finally, appearance inspection and packaging are carried out.

[0003] However, all of the above tasks are done manually, which is inefficient and makes it difficult to guarantee quality. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a common-mode inductor production equipment that can partially automate the common-mode inductor production process, improve production efficiency, and help improve product quality.

[0005] The present invention also proposes a common mode inductor production method applicable to the aforementioned common mode inductor production equipment.

[0006] According to a first aspect of the present invention, a common mode inductor production apparatus includes a turntable and a plurality of processing devices distributed circumferentially along the turntable;

[0007] Multiple fixtures are evenly distributed on the turntable. Each fixture has a positioning cavity for accommodating the common mode inductor, such that the pins of the common mode inductor are arranged along the radial direction of the turntable and away from the center of the turntable.

[0008] Several of the processing devices include a wire breaking and stripping device, which includes a stripping assembly and a wire cutting assembly;

[0009] The tangent assembly includes a radial translation seat, an anvil plate disposed on the translation seat, a tangent plate disposed above the anvil plate, and a lifting component for mounting the tangent plate. The anvil plate is provided with a broken wire collection cavity on the side away from the center of the turntable.

[0010] The peeling assembly is located on the side of the anvil near the center of the turntable. The peeling assembly includes a lower half-enclosing member connected to the radial translation seat and an upper half-enclosing member disposed above the lower half-enclosing member. The lower half-enclosing member and the upper half-enclosing member cooperate to form a peeling heating cavity for accommodating the pin. The top of the upper half-enclosing member is elastically connected to the lifting member.

[0011] At least one of the upper half-enclosing member and the lower half-enclosing member is provided with a heating element, the heating element being used to heat the portion of the pin located within the peeling heating cavity;

[0012] One of the upper and lower enclosure components is provided with an air intake channel connecting the outside and the peeling heating chamber, and the air intake channel is provided with a one-way air intake valve. The other of the upper and lower enclosure components is provided with an exhaust channel connecting the peeling heating chamber and an external air extraction device.

[0013] A common-mode inductor production apparatus according to an embodiment of the present invention has at least the following beneficial effects:

[0014] This invention, by setting up a turntable and processing devices, allows common-mode inductors to be placed on tooling on the turntable. Then, by rotating the turntable, the tooling is placed on different processing devices, thereby enabling the sequential automatic processing of common-mode inductors, improving production efficiency. At the same time, the processing quality has a high degree of consistency, which is beneficial to improving product quality.

[0015] By incorporating a wire cutting and stripping device, this invention enables a single processing unit to integrate both wire cutting and stripping functions. This reduces the number of processing units, lowers manufacturing costs, and increases the integration level of the equipment. It also helps reduce space requirements and facilitates the placement of more processing units in common mode inductor production equipment, thereby further enhancing the automation level of the common mode inductor production process.

[0016] This invention, by setting a radial translation seat, allows different parts of the pin to be located in the wire cutting assembly and the stripping assembly when the radial translation seat is close to the turntable. This satisfies both the need to shorten the pin during wire cutting and the need to strip the insulation material, without the need for complex operations, thus simplifying the equipment structure.

[0017] By setting up an upper half-enclosing part and a lower half-enclosing part, the present invention can also facilitate the formation of a peeling heating chamber, which can reduce heat loss, facilitate the fusion of insulating materials by heating, and prevent the exhaust gas generated by the fusion of insulating materials from flying outward.

[0018] By providing an exhaust channel, this invention also facilitates the extraction of exhaust gas from the diaphragm heating chamber, avoiding the release of exhaust gas into the air during the disconnection and diaphragm removal of another common-mode inductor, thus reducing air pollution.

[0019] By setting a one-way air intake valve, this invention also facilitates the replenishment of air into the peeling heating chamber, thus preventing the formation of a vacuum in the peeling heating chamber and making it difficult for exhaust gas to be discharged.

[0020] At the same time, the one-way air intake valve is less likely to leak air outwards, which helps reduce air pollution.

[0035] A common-mode inductor manufacturing method according to a second aspect of the present invention is applied to a common-mode inductor manufacturing equipment described in any one of the above claims;

[0036] The common-mode inductor manufacturing method includes a wire breakage and stripping section, which includes:

[0037] In the workstation alignment step, the turntable rotates so that the pins of the common mode inductor of the tooling are aligned with the radial translation seat; the radial translation seat moves closer to the turntable so that the pins pass through the lower half-enclosure and the anvil piece in sequence.

[0038] In the peeling step, the lifting component descends so that the upper half of the enclosure component and the lower half of the enclosure component cooperate to form the peeling heating chamber; the heating component heats the peeling heating chamber to vaporize the insulating material on the outer surface of the pin; the exhaust channel operates to discharge the vaporized insulating material, while the one-way air intake valve supplies external air into the peeling heating chamber.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] The following description, in conjunction with the accompanying drawings, describes a common-mode inductor production equipment and production method according to an embodiment of the present invention.

[0060] Reference Figures 1 to 6 This invention aims to provide an embodiment of a common-mode inductor production equipment. Meanwhile, referring to... Figure 7 and Figure 8 The present invention also aims to provide an embodiment of a common-mode inductor manufacturing method, which is applied to... Figures 1 to 6 Common mode inductor production equipment.

[0061] In this embodiment, the common mode inductor production equipment and method can achieve partial or even full automation of the common mode inductor 3 production process, improve production efficiency, and help improve product quality.

[0062] Structurally, refer to Figure 1 The production equipment includes a turntable 1 and several processing devices.

[0063] The turntable 1 is provided with multiple fixtures 2 evenly distributed on it. Each fixture 2 has a positioning cavity for accommodating a common mode inductor 3, so that the pins 4 of the common mode inductor 3 are arranged along the radial direction of the turntable 1 and away from the center of the turntable 1.

[0064] In some specific embodiments of the present invention, the tooling 2 may be provided with an elastic inner liner, thereby facilitating the placement and removal of the common mode inductor 3 and simplifying the structure of the tooling 2.

[0065] In some specific embodiments of the present invention, the elastic liner can be connected to a spring, thereby allowing the elastic liner to maintain its elasticity for a long time and be durable. Furthermore, by replacing the spring, different elastic clamping requirements can be met.

[0066] The machining devices are distributed around the circumference of the turntable 1. Therefore, when the turntable 1 rotates, the tooling 2 can be placed at each machining device in sequence, thereby completing the machining in order.

[0067] In some specific embodiments of the present invention, several processing devices can be evenly distributed, or some adjacent processing devices can be staggered by more than twice the angle of one rotation of the turntable 1. This allows for reasonable space allocation, reduces the difficulty of layout, and ensures that the common mode inductor 3 of the previous process has sufficient time to meet cooling and other requirements before entering the next process, thus avoiding affecting the production cycle.

[0068] Several processing devices include a wire breaking and stripping device 5, a tube packing and tinning device 26, and a test sleeve device 38.

[0069] Reference Figure 2 and Figure 3The wire-cutting and stripping device 5 includes a stripping component and a wire-cutting component.

[0070] Specifically, the tangent assembly includes a radial translation seat 6, an anvil 7 disposed on the translation seat, a tangent 8 disposed above the anvil 7, and a lifting component 9 for mounting the tangent 8. A broken wire collection cavity 10 is provided on the side of the anvil 7 away from the center of the turntable 1.

[0071] The peeling assembly is located on the side of the cutting board 7 near the center of the turntable 1. The peeling assembly includes a lower half-enclosing part 11 connected to the radial translation seat 6 and an upper half-enclosing part 12 disposed above the lower half-enclosing part 11. The lower half-enclosing part 11 and the upper half-enclosing part 12 cooperate to form a peeling heating cavity 13 for accommodating the pin 4. The top of the upper half-enclosing part 12 is elastically connected to the lifting part 9. The lifting movement of the lifting part 9 can be achieved by pneumatic power, hydraulic power or the cooperation of a motor and a screw.

[0072] In addition, at least one of the upper half-enclosing member 12 and the lower half-enclosing member 11 is provided with a heating element for heating the portion of the pin 4 located within the peeling heating cavity 13.

[0073] Reference Figure 2 The upper half enclosure 12 is elastically connected to the lifting member 9 at the top. The upper half enclosure 12 is connected to the lifting member 9 through a guide post and a spring. Therefore, when the upper half enclosure 12 contacts the lower half enclosure 11, the distance between the upper half enclosure 12 and the lifting member 9 can be reduced to meet the need for the lifting member 9 to drive the tangent member 8 down to cut off the pin 4.

[0074] In some specific embodiments of the present invention, the upper half-enclosing member 12 may have a lower half-coil, and the upper half-enclosing member 12 may have an upper half-coil. When the upper half-enclosing member 12 and the lower half-enclosing member 11 are attached, the lower half-coil and the upper half-coil cooperate to form a complete coil. Furthermore, the coil surrounds the pin 4 and can heat the pin 4 by electromagnetic induction, which is more efficient.

[0075] In some specific embodiments of the present invention, the heating element can be a heating resistance wire or a heating tube, and the heating element should be placed as close as possible to pin 4 to improve heating efficiency.

[0076] Furthermore, one of the upper half-enclosing member 12 and the lower half-enclosing member 11 is provided with an air intake channel 14 connecting the outside and the peeling heating chamber 13, and the air intake channel 14 is provided with a one-way air intake valve 15. The other of the upper half-enclosing member 12 and the lower half-enclosing member 11 is provided with an exhaust channel 16 connecting the peeling heating chamber 13 and the external air extraction device.

[0077] In summary, this embodiment, by setting up a turntable 1 and a processing device, allows the common mode inductor 3 to be placed on the fixture 2 on the turntable 1. Then, by rotating the turntable 1, the fixture 2 is placed in different processing devices, thereby enabling the sequential automatic processing of the common mode inductor 3, improving production efficiency. At the same time, the processing quality has high consistency, which is beneficial to improving product quality.

[0078] This embodiment, by setting up the wire cutting and stripping device 5, enables a single processing device to integrate both wire cutting and stripping functions. This helps reduce the number of processing devices and lower manufacturing costs. At the same time, it increases the integration level of the equipment, which helps reduce the space occupied and facilitates the arrangement of more processing devices in the common mode inductor production equipment, thereby further improving the automation level of the common mode inductor 3 production process.

[0079] In this embodiment, by setting a radial translation seat 6, when the radial translation seat 6 is close to the turntable 1, different parts of the pin 4 can be located in the wire cutting assembly and the stripping assembly. This satisfies both the need to shorten the pin 4 when cutting the wire and the need to strip the insulation material, without the need for complicated actions, thus simplifying the equipment structure.

[0080] In this embodiment, by setting the upper half-enclosing part 12 and the lower half-enclosing part 11, it is also convenient to form the peeling heating chamber 13, which can reduce heat loss, facilitate the melting of insulating materials by heating, and prevent the exhaust gas generated by the melting of insulating materials from flying outward.

[0081] In this embodiment, by setting up an exhaust channel 16, it is also convenient to extract exhaust gas from the peeling heating chamber 13, avoiding the exhaust gas being discharged into the air when the other common mode inductor 3 is being peeled, thus reducing air pollution.

[0082] By setting a one-way air intake valve 15, the present invention also facilitates the replenishment of air to the peeling heating chamber 13, thereby preventing the peeling heating chamber 13 from forming a vacuum and making it difficult for waste gas to be discharged.

[0083] At the same time, the one-way air intake valve 15 is less likely to leak air outward, which helps to reduce air pollution.

[0084] In some specific embodiments of the present invention, the lower half of the enclosure 11 may be provided with a lower left half ring 17, which is used to accommodate and position the pin 4. The lower left half ring 17 is located on the side of the peeling heating cavity 13 away from the anvil 7, and the lower left half ring 17 is provided with a lower cooling channel 18.

[0085] It is easy to understand that in this embodiment, by setting the lower left half ring 17 and providing a lower cooling channel 18 on the lower left half ring 17, when the heating pin 4 is peeled, the lower cooling channel 18 is filled with a cooling medium, which reduces the temperature of the lower left half ring 17 and can absorb the heat transferred from the pin 4 to the common mode inductor 3 body.

[0086] In some specific embodiments of the present invention, the upper half of the enclosure 12 may be provided with a left upper half ring 19, which is used to accommodate and position the pin 4. The left upper half ring 19 is located on the side of the peeling heating cavity 13 away from the anvil 7, and the left upper half ring 19 is provided with an upper cooling channel 20.

[0087] It is easy to understand that in this embodiment, by setting the upper left half ring 19 and providing an upper cooling channel 20 on the upper left half ring 19, when the heating pin 4 is peeled, the upper cooling channel 20 is circulated with a cooling medium, which reduces the temperature of the upper left half ring 19 and can absorb the heat transferred from the pin 4 to the common mode inductor 3 body.

[0088] It is easy to understand that by setting the upper left half ring 19 and the lower left half ring 17, this embodiment can surround the pin 4, fully absorb heat, reduce the heat transferred to the common mode inductor 3 body, and reduce thermal impact.

[0089] In some specific embodiments of the present invention, the lower half of the enclosure 11 may be provided with a lower right half ring 21, which is located on the side of the peeling heating chamber 13 near the anvil 7. The lower right half ring 21 can be elastically raised and lowered, and the inner side of the lower right half ring 21 is provided with a lower right inner ring blade 22 that abuts against the outer surface of the pin 4.

[0090] It is easy to understand that by setting the lower right half ring 21, the lower right half ring 21 has a lower right inner ring blade 22, which also facilitates the scraping of the surface of the pin 4, and avoids the part of the pin 4 near the broken wire assembly from being underheated and affecting the peeling quality. The part of the pin 4 near the broken wire assembly is mainly used for solder adhesion. Insufficient peeling will seriously affect the solder adhesion quality and also affect the conductivity of the pin 4.

[0091] In some specific embodiments of the present invention, the upper half of the surrounding part 12 may be provided with a right upper half ring 23, which is located on the side of the peeling heating chamber 13 near the anvil part 7. The right upper half ring 23 can be elastically raised and lowered, and the inner side of the right upper half ring 23 is provided with a right upper inner ring blade 24 that abuts against the outer surface of the pin 4.

[0092] It is easy to understand that by setting the upper right half ring 23, the upper right half ring 23 has an upper right inner ring blade 24, which also facilitates the scraping of the surface of the pin 4, and avoids insufficient heating of the part of the pin 4 near the broken wire assembly, which affects the peeling quality. The part of the pin 4 near the broken wire assembly is mainly used for solder adhesion. Insufficient peeling will seriously affect the solder adhesion quality and also affect the conductivity of the pin 4.

[0093] It is easy to understand that by setting the lower right half ring 21 and the upper right half ring 23, this embodiment can also facilitate the complete surrounding of the pin 4, thereby reducing the scraping blind area and improving the peeling quality.

[0094] In some specific embodiments of the present invention, the inner surface of the broken wire collection cavity 10 can be matched with the outer contour of the tangent 8. When the tangent 8 descends, the inner surface of the broken wire collection cavity 10 can cooperate with the outer contour of the tangent 8 to cover the top of the broken wire collection cavity 10.

[0095] It is easy to understand that, in this embodiment, by matching the inner surface of the broken wire collection cavity 10 with the outer contour of the tangent member 8, waste material can be blocked.

[0096] In some specific embodiments of the present invention, a discharge guide 25 may be provided on the side of the broken wire collection cavity 10 near the anvil 7, and the discharge guide 25 is used to guide the cut waste material into the broken wire collection cavity 10.

[0097] It is easy to understand that, by setting the discharge guide trough 25, this embodiment also facilitates the introduction of waste material into the broken wire collection chamber 10 for discharge and collection, so as to avoid the waste material from scattering and affecting the cleanliness of the site and the cleanliness of the product.

[0098] Reference Figure 4 and Figure 5 For the tube-loading hot soldering device 26, the tube-loading hot soldering device 26 includes a tube-loading assembly and a hot soldering assembly, with the tube-loading assembly located above the hot soldering assembly.

[0099] In addition, the fixture 2 can be flipped so that the side of the fixture 2 closest to the center of the turntable 1 is tilted up, so that the tube assembly is aligned with the common mode inductor 3 for tube assembly, and the end of the pin 4 is immersed in the solder pool 36 of the hot soldering assembly.

[0100] It is easy to understand that by setting up the tube mounting assembly and the hot soldering assembly, this embodiment can also facilitate the hot soldering and tube mounting of the common mode inductor 3 in the same location, which improves the equipment integration, helps to reduce the footprint, and facilitates layout and implementation.

[0101] In some specific embodiments of the present invention, a rotating shaft 27 connecting the turntable 1 can be provided on the side of the tooling 2 away from the center of the turntable 1. A lifting structure for lifting the tooling 2 is provided below the turntable 1. The lifting structure includes a track 29 and a ball bearing 28 that rolls along the track 29. The track 29 has a climbing section, a descending section, and a smooth section connecting the climbing section and the descending section. One of the track 29 and the ball bearing 28 is provided on the tooling 2, and the other of the track 29 and the ball bearing 28 is provided on the frame. The frame is used to install the turntable 1.

[0102] That is, when the turntable 1 rotates, the ball bearing 28 moves along the track 29, passing through the climbing section, the smoothing section and the descending section in sequence, so that the fixture 2 is raised and held for a period of time before descending, which can form the posture required for tube loading and hot soldering, thus meeting the needs of tube loading and hot soldering.

[0103] Reference Figure 4 and Figure 5In some specific embodiments of the present invention, the tube assembly may include a tube assembly 30, the tube assembly 30 having an inclined tube assembly channel 32 for receiving the tube 31 through which a common mode inductor 3 is inserted, the bottom end of the inclined tube assembly channel 32 being a tube outlet 33, the top end of the inclined tube assembly channel 32 being a tube inlet 34, and a limiting member 35 being arranged in the radial direction of the inclined tube assembly channel 32, the limiting member 35 entering the inclined tube assembly channel 32 to prevent the tube 31 from moving downward, and the limiting member 35 moving away from the inclined tube assembly channel 32 to release the tube 31.

[0104] Since the feed tube 31 enters the common mode inductor 3 at an angle along the inclined tube loading channel 32, the front and rear feed tubes 31 will be supported, so that the limiting component 35 can easily clamp the feed tube 31, preventing the feed tube 31 from falling continuously and not affecting the rotation switching of the turntable 1.

[0105] In some specific embodiments of the present invention, the number of limiting members 35 can be two, so that the limiting members 35 alternately limit two adjacent material tubes 31, so as to realize the intermittent loading of material tubes 31 and meet the production needs.

[0106] In some specific embodiments of the present invention, the soldering assembly may include a solder pool 36 and a gas collection hood 37 located on top of the solder pool 36. The gas collection hood 37 is installed on the mounting pipe 30 to simplify the setup and reduce the difficulty of arrangement.

[0107] Reference Figure 6 For the test sleeve device 38, the test sleeve device 38 includes a sleeve assembly and a test assembly. The sleeve assembly includes a sleeve chamber 39. The sleeve chamber 39 has a sleeve channel 41 for accommodating a plastic tube 40 to pass through and be sleeved on the pin 4. One end of the sleeve channel 41 is an outlet 42, and the other end of the sleeve channel 41 is provided with a pusher for pushing the plastic tube 40 toward the pin 4 to complete the sleeve. The radial top of the sleeve channel 41 is provided with an inlet 43, which is connected to a feeding conveyor or a feeding storage chamber.

[0108] That is, the plastic tube 40 of the feeding conveyor or feeding storage bin enters the sleeve channel 41 from the inlet 43. Then, the pusher pushes the plastic tube 40, causing the plastic tube 40 to move toward the outlet 42, so that the plastic tube 40 is fitted onto the pin 4, completing the sleeve operation.

[0109] In some specific embodiments of the present invention, the push tube component may include a push rod 45 and a push tube 44 fitted onto the push rod 45, the end of the push tube 44 being used to abut against and push the plastic tube 40.

[0110] It is easy to understand that by setting the push rod 45 and the push tube 44 in this embodiment, it is also convenient to contact the edge of the plastic tube 40, so as to facilitate the movement of the plastic tube 40. At the same time, it avoids the push tube 44 from touching the pin 4 and causing the pin 4 to deform.

[0111] In addition, the empty space inside the push tube 44 makes it convenient to arrange the testing section, thus completing two operations with one action and improving the integration of the equipment.

[0112] In some specific embodiments of the present invention, the test component may include a conductive test end disposed on the push rod 45. The conductive test end is located on the side of the push rod 45 near the push tube 44 and inside the push tube 44. The conductive test end includes a conductive contact 46 and an elastic conductive part 47 connected to the conductive contact 46. The push rod 45 is provided with a conductive inner core 48 connected to the elastic conductive part 47.

[0113] It is easy to understand that, through the conductive inner core 48, conductive contact 46 and elastic conductive part 47, this embodiment also enables the conductive test end to elastically contact the pin 4, which facilitates the power-on detection operation. It integrates multiple functions, simplifies and reduces processing steps, and improves production efficiency.

[0114] Reference Figure 7 and Figure 8 The common mode inductor manufacturing method includes a wire breakage and stripping process, which includes:

[0115] In the station alignment step S1, the turntable 1 rotates so that the pin 4 of the common mode inductor 3 of the tooling 2 is facing the radial translation seat 6; the radial translation seat 6 moves closer to the turntable 1 so that the pin 4 passes through the lower half-enclosure 11 and the anvil 7 in sequence.

[0116] In peeling step S2, the lifting member 9 descends so that the upper half-enclosing member 12 and the lower half-enclosing member 11 cooperate to form the peeling heating chamber 13; the heating member heats the peeling heating chamber 13 so that the insulating material on the outer surface of the pin 4 vaporizes; the exhaust channel 16 operates to discharge the vaporized insulating material, and at the same time, the one-way air inlet valve 15 replenishes the external air into the peeling heating chamber 13.

[0117] In the wire breaking step S3, the lifting member 9 continues to descend, and the cutting member 8 and the anvil member 7 squeeze the pin 4 to cut the pin 4 to a fixed length and generate waste. The waste falls into the wire breaking collection cavity 10, and then the lifting member 9 and the radial translation seat 6 are reset.

[0118] In some specific embodiments of the present invention, the lower half-enclosing member 11 may be provided with a lower left half-ring 17, which is used to accommodate and position the pin 4. The lower left half-ring 17 is located on the side of the peeling heating cavity 13 away from the anvil member 7, and the lower left half-ring 17 is provided with a lower cooling channel 18; the upper half-enclosing member 12 may be provided with a upper left half-ring 19, which is used to accommodate and position the pin 4. The upper left half-ring 19 is located on the side of the peeling heating cavity 13 away from the anvil member 7, and the upper left half-ring 19 is provided with an upper cooling channel 20.

[0119] Meanwhile, the lower half of the enclosure 11 is provided with a lower right half ring 21, which is located on the side of the peeling heating chamber 13 near the anvil 7. The lower right half ring 21 can be elastically raised and lowered, and the inner side of the lower right half ring 21 is provided with a lower right inner ring blade 22 that abuts against the outer surface of the pin 4. The upper half of the enclosure 12 is provided with a upper right half ring 23, which is located on the side of the peeling heating chamber 13 near the anvil 7. The upper right half ring 23 can be elastically raised and lowered, and the inner side of the upper right half ring 23 is provided with an upper right inner ring blade 24 that abuts against the outer surface of the pin 4.

[0120] Therefore, in the peeling step S2, the lower cooling channel 18 of the lower left half ring 17 is supplied with cooling medium, and the upper cooling channel 20 of the upper left half ring 19 is supplied with cooling medium. The lower left half ring 17 and the upper left half ring 19 work together to absorb heat, so as to reduce the heat transfer from the pin 4 to the body of the common mode inductor 3.

[0121] Therefore, in the wire breaking step S3, the lifting member 9 and the radial translation seat 6 are reset. This includes the radial translation seat 6 being reset a certain distance so that the lower right half ring 21 and the upper right half ring 23 cooperate to scrape the outer surface of the pin 4. Then, the lifting member 9 and the radial translation seat 6 are reset to the starting point.

[0122] In addition, the common mode inductor production method also includes the tube hot soldering step S4.

[0123] In the tube loading and soldering step S4, the turntable 1 rotates, and the ball bearing 28 moves along the climbing section to the smooth section, causing the fixture 2 to tilt, so that the pin 4 of the common mode inductor 3 on the fixture 2 is immersed in the solder pool 36. At the same time, the common mode inductor 3 is aligned with the tube loading component 30. Then, the limiting component 35 retracts, so that the tube 31 moves along the inclined tube loading channel 32. The tube 31 enters the common mode inductor 3 through the tube outlet 33, while another tube 31 enters the inclined tube loading channel 32 from the tube inlet 34. Then, the limiting component 35 re-enters the inclined tube loading channel 32 and abuts against the tube 31, preventing the new tube 31 from moving.

[0124] Next, turntable 1 continues to rotate, ball 28 moves from the smooth section to the descending section, fixture 2 resets, and pin 4 is removed from solder pool 36.

[0125] In addition, the common mode inductor manufacturing method also includes a test bushing step S5.

[0126] In the test sleeve step S5, the plastic tube 40 of the feeding conveyor or feeding storage bin enters the sleeve channel 41 from the inlet 43. The push tube 44 of the pusher pusher pushes the plastic tube 40 to move. The plastic tube 40 moves from the outlet 42 to the pin 4, so that the plastic tube 40 is fitted onto the pin 4.

[0127] As the push tube continues to move, the conductive contact 46 inside the push tube 44 contacts the pin 4, while the elastic conductive part 47 is compressed.

[0128] When the conductive core 48 is energized, the current or electrical signal passes through the elastic conductive part 47, the conductive contact 46 and the pin 4 and enters the common mode inductor 3 for detection.

[0129] After the test is completed, the tube is pushed back into place, the conductive contact 46 separates from the pin 4, and the new plastic tube 40 enters the sleeve channel 41 from the inlet 43, so that the next sleeve test can be performed.

[0130] In this embodiment, a loading step and a unloading step are also included. The loading step and the unloading step can be completed manually or by a robot, which is quite common. Since they are not key improvement points, they will not be described in detail.
