As AI technology is increasingly used in all walks of life, artificial intelligence has become an important driving force for a new round of scientific and technological revolution and industrial transformation. The key to supporting the rapid development of artificial intelligence technology lies in the large-scale production and application of AI servers with high-performance computing capabilities and large-capacity storage space, which has led to a significant increase in the demand for inductors related to AI servers.

[0028] The automatic paint stripping and soldering winding process for AI server inductors of the present invention is implemented by the following technical solutions:

[0029] The automated paint stripping, soldering and winding process for AI server inductors is applied to the automated paint stripping, soldering and winding machine as described above, and the process includes the following steps:

[0030] Pay-off steps: the pay-off motor drives the copper wire shaft to rotate so that the copper wire shaft pays out the flat copper wire, and the tensioning mechanism receives the flat copper wire paid out by the copper wire shaft and tensions the flat copper wire;

[0031] Paint stripping step: the paint stripping device performs paint stripping process on the flat copper wire;

[0032] Soldering step: The soldering device performs soldering process on the flat copper wire;

[0033] The winding step includes the following sub-steps:

[0034] Wire winding sub-step ①: The feeding clamping assembly clamps the flat copper wire passing through the wire feeding nozzle, and further pulls the flat copper wire outward by a preset distance, so that the wire end of the flat copper wire with the solder portion passes through the clamping position of the winding upper mold assembly and the winding lower mold assembly;

[0035] Wire winding sub-step ②: the winding upper mold assembly and the winding lower mold assembly are molded together to compress the flat copper wire, and the feeding clamping assembly releases the flat copper wire;

[0036] Winding sub-step ③: The winding upper die assembly and the winding lower die assembly perform winding action on the flat copper wire. During the winding process, the automatic wire feeding assembly continuously pulls the flat copper wire out of the soldering device and feeds it into the wire feeding nozzle. The wire pulling action of the automatic wire feeding assembly drives the flat copper wire to be continuously pulled out of the paint stripping device and fed into the soldering device, and drives the flat copper wire to be continuously pulled out of the tensioning mechanism and fed into the paint stripping device.

[0037] Winding sub-step ④: the feeding clamping assembly clamps the flat copper wire between the clamping position of the winding upper mold assembly and the winding lower mold assembly and the wire outlet end of the wire feeding nozzle, and the shearing assembly shears the flat copper wire between the clamping position of the winding upper mold assembly and the winding lower mold assembly and the clamping position of the feeding clamping assembly, and the cutting point is between two adjacent soldering positions of the flat copper wire; in this winding sub-step ④, the automatic wire feeding assembly resets after the feeding clamping assembly clamps the flat copper wire.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The automatic paint stripping, soldering and winding machine of the present invention can tighten the flat copper wire in the automatic processing process through the tensioning mechanism, thereby ensuring the processing accuracy of the flat copper wire in the subsequent processes, especially the paint stripping process and the winding process have high requirements for processing accuracy. The automatic paint stripping, soldering and winding machine performs paint stripping and soldering processes on the flat copper wire through the paint stripping device and the soldering device;

[0040] In the winding device of the automatic paint stripping, soldering and winding integrated machine, the winding upper mold assembly and the winding lower mold assembly can perform a winding action on the flat copper wire to form a coil when the mold is closed; but since the flat copper wire has passed through the tensioning mechanism, the paint stripping device and the soldering device in sequence before winding, these mechanisms or devices can give the flat copper wire a large resistance, and the flat copper wire has accumulated a relatively large length when passing through these mechanisms or devices, so the dead weight of the flat copper wire also adds a large resistance to the winding action, which makes it difficult for the winding upper mold assembly and the winding lower mold assembly to perform the winding action, and even cannot press and hang the flat copper wire, so in the present invention, the winding device is equipped with an automatic wire feeding assembly, which is used to continuously and cooperatively feed the wire during winding to solve the problem of excessive winding resistance;

[0041] In addition, since the flat copper wire has been tensioned, when the automatic wire feeding assembly continuously pulls the flat copper wire out of the soldering device and feeds it into the wire feeding nozzle, the wire pulling action of the automatic wire feeding assembly will drive the flat copper wire to be continuously pulled out of the paint stripping device and fed into the soldering device, and drive the flat copper wire to be continuously pulled out of the tensioning mechanism and fed into the paint stripping device. Therefore, when the winding action is completed, the wire pulling action is synchronously completed at this time, so that the section of flat copper wire originally processed by the paint stripping device / soldering device is pulled out, and a new section of flat copper wire is fed into the paint stripping device / soldering device, and the moving distance of the flat copper wire is accurately controlled (the moving distance = the wire feeding distance of the feeding clamping assembly + the wire feeding distance of the automatic wire feeding assembly), which enables the processing position or processing interval of the paint stripping device to be accurately controlled. The present invention well realizes the coordination of paint stripping, soldering and winding processes, and thus can realize the integrated automatic production of paint stripping, soldering and winding.

[0042] In the winding device of the automatic paint stripping, soldering and winding machine, the feeding clamping assembly is used to pull the flat copper wire outward by a preset distance, so that the wire end of the flat copper wire passes through the clamping position of the winding upper mold assembly and the winding lower mold assembly, so that the wire end can form a pin of the coil after the winding action is completed; the shearing assembly shears the flat copper wire, the purpose of which is to separate the wound coil from the flat copper wire as a whole, and form another pin of the coil at the position of the shearing point;

[0043] It can be seen from the above that the automatic paint stripping, soldering and winding integrated machine of the present invention can realize the integrated automatic production of paint stripping, soldering, winding and other processes of the inductor flat copper coil, thereby reducing labor costs and improving production efficiency.

[0044] (2) The automatic paint stripping, soldering and winding process of the present invention is applied to the automatic paint stripping, soldering and winding machine as described above, which can realize the integrated automatic production of paint stripping, soldering and winding processes of the flat copper coil of the inductor, thereby reducing labor costs and improving production efficiency.

[0072] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0073] refer to Figure 1-Figure 19 The preferred embodiment of the present invention provides an automatic paint stripping, soldering and winding machine for AI server inductors and an automatic paint stripping, soldering and winding process for AI server inductors. The automatic paint stripping, soldering and winding machine of this embodiment includes a frame 7 (most of the structure of the frame 7 is omitted in the drawings) and a pay-off motor 1, a tensioning mechanism 2, a paint stripping device 3, a soldering device 4, a winding device 5 and a blanking assembly 6 arranged on the frame 7.

[0074] The pay-off motor 1 is used to drive the copper wire shaft 11 to rotate so as to pay out the flat copper wire. The pay-off motor 1 may be a stepper motor or a servo motor.

[0075] The tensioning mechanism 2 is used to receive the flat copper wire released from the copper wire reel 11 and tension the flat copper wire.

[0076] The paint stripping device 3 is used to receive the rectangular copper wire from the tensioning mechanism 2 and perform a paint stripping process on the rectangular copper wire.

[0077] The soldering device 4 receives the rectangular copper wire from the paint stripping device 3 and performs a soldering process on the rectangular copper wire.

[0078] The winding device 5 includes a wire feeding nozzle 51, an automatic wire feeding assembly 52, a material feeding clamping assembly 53, a winding upper mold assembly 54, a winding lower mold assembly 55 and a shearing assembly 56. Among them, the automatic wire feeding assembly 52 is used to pull the flat copper wire out of the soldering device 4 and feed it into the wire feeding nozzle 51; the material feeding clamping assembly 53 is used to clamp the flat copper wire passing through the wire feeding nozzle 51 and pull the flat copper wire outward by a preset distance; the winding upper mold assembly 54 and the winding lower mold assembly 55 are used to press the flat copper wire when closing the mold and perform a winding action on the flat copper wire; the shearing assembly 56 is used to shear the flat copper wire after the winding action is completed.

[0079] The blanking assembly 6 is used to receive the coil formed by the winding device 5 .

[0080] The automated paint stripping and soldering wire winding process of the present embodiment is applied to the automated paint stripping and soldering wire winding integrated machine as described in the present embodiment. The automated paint stripping and soldering wire winding process includes a wire laying step, a paint stripping step, a soldering step, a winding step and a material unloading step.

[0081] Wire-releasing steps: the wire-releasing motor 1 drives the copper wire shaft 11 to rotate so that the copper wire shaft 11 releases the flat copper wire, and the tensioning mechanism 2 receives the flat copper wire released by the copper wire shaft 11 and tensions the flat copper wire.

[0082] Paint stripping step: the paint stripping device 3 performs a paint stripping process on the rectangular copper wire.

[0083] Soldering step: The soldering device 4 performs a soldering process on the rectangular copper wire.

[0084] The winding step includes winding sub-steps ① to ④.

[0085] Winding sub-step ①: The loading clamping assembly 53 clamps the flat copper wire passing through the wire feeding nozzle 51, and further pulls the flat copper wire outward by a preset distance (i.e., the wire feeding distance of the loading clamping assembly 53), so that the wire end of the flat copper wire with the solder portion passes through the clamping position of the winding upper mold assembly 54 and the winding lower mold assembly 55.

[0086] Winding sub-step ②: The winding upper mold assembly 54 and the winding lower mold assembly 55 are closed to compress the flat copper wire, and the feeding clamping assembly 53 releases the flat copper wire.

[0087] Winding sub-step ③: The winding upper mold assembly 54 and the winding lower mold assembly 55 perform a winding action on the flat copper wire. During the winding process, the automatic wire feeding assembly 52 continuously pulls the flat copper wire from the soldering device 4 and feeds it into the wire feeding nozzle 51. The wire pulling action of the automatic wire feeding assembly 52 drives the flat copper wire to be continuously pulled out from the paint stripping device 3 and fed into the soldering device 4, and drives the flat copper wire to be continuously pulled out from the tensioning mechanism 2 and fed into the paint stripping device 3. In this winding sub-step ③, the winding action and the wire pulling action (or wire feeding action) of the automatic wire feeding assembly 52 are performed simultaneously and collaboratively.

[0088] Winding sub-step ④: the loading and clamping assembly 53 clamps the flat copper wire between the clamping position of the winding upper mold assembly 54 and the winding lower mold assembly 55 and the wire outlet end of the wire feeding nozzle 51, and the shearing assembly 56 shears the flat copper wire between the clamping position of the winding upper mold assembly 54 and the winding lower mold assembly 55 and the clamping position of the loading and clamping assembly 53, and the cutting point is between two adjacent soldering positions of the flat copper wire; in this winding sub-step ④, the automatic wire feeding assembly 52 resets after the loading and clamping assembly 53 clamps the flat copper wire.

[0089] Unloading step: the unloading assembly 6 receives the coil formed by the winding device 5 .

[0090] To avoid confusion, the winding sub-step ④ is further explained here: if the clamping position of the winding upper mold assembly 54 and the winding lower mold assembly 55 is A, and the wire outlet end of the wire feeding nozzle 51 is B, then the clamping position C of the flat copper wire of the loading clamping assembly 53 is between A and B, and the cutting point D of the flat copper wire of the shearing assembly 56 is between A and C.

[0091] Regarding the order of each step of the process of this embodiment. For example, the wire-releasing step and the soldering step can be set to be independent. The wire-releasing step is completed by the wire-releasing motor 1 and the tensioning mechanism 2, and the copper wire amount that can process multiple coils can be released at one time; the soldering step is continuously performed by the soldering device 4, and only the paint-stripped position on the flat copper wire can be tinned, and there is no need to pause during the processing of the entire effective copper wire amount of the copper wire shaft 11; therefore, the wire-releasing step and the soldering step can be set to be independent.

[0092] In the winding step, the winding sub-steps ① to ④ are performed in the order of numbers; when the winding sub-steps ① to ④ are completed in sequence, the moving distance of the flat copper wire = the feeding distance of the feeding clamping component 53 + the moving distance of the automatic wire feeding component 52, at this time, the section of flat copper wire that was originally stripped by the paint stripping device 3 is pulled out, and a new section of flat copper wire (to be stripped) is fed in, so the paint stripping device 3 can be arranged to strip the new section of flat copper wire at this time; in addition, when the winding sub-steps ① to ④ are completed in sequence, the feeding clamping component 53 has clamped the flat copper wire passing through the wire feeding nozzle 51, and the automatic wire feeding component 52 has been reset, so the paint stripping step and the unloading step can be combined for cyclic processing. For example: ······→winding step→unloading step+paint stripping step→winding step→unloading step+paint stripping step→·······.

[0093] That is, the order of the steps in the process of this embodiment can be arranged as follows:

[0094] The wire-releasing step is executed periodically, and the wire-releasing motor 1 and the tensioning mechanism 2 coordinate the wire-releasing action, and can release the copper wire amount capable of producing multiple coils at one time;

[0095] The soldering step is continuously performed, and the soldering device 4 can continuously perform the soldering process during the processing of the entire effective copper wire amount of the copper wire spool 11;

[0096] The winding step, paint stripping step and unloading step are executed cyclically, that is: ······→winding step→unloading step+paint stripping step→winding step→unloading step+paint stripping step→······.

[0097] The automatic paint stripping, soldering and winding integrated machine and process of the embodiment of the present invention can tighten the flat copper wire during the automatic processing through the tensioning mechanism 2, thereby ensuring the processing accuracy of the flat copper wire in subsequent processes, especially the paint stripping process and the winding process have high requirements on processing accuracy.

[0098] Regarding how to realize periodic automatic pay-off, the tensioning mechanism 2 can be designed as follows. The tensioning mechanism 2 includes a support frame 21, a first fixed shaft 22, a movable shaft 23, a second fixed shaft 24, a rotating shaft 25, a rotating arm 26, a tensioning spring 27 and a fulcrum structure 28; the first fixed shaft 22 and the second fixed shaft 24 are mounted on the support frame 21, the rotating shaft 25 is rotatably connected to the support frame 21, the movable shaft 23 is mounted on one end of the rotating arm 26, the other end of the rotating arm 26 is fixed to the rotating shaft 25, the axial directions of the first fixed shaft 22, the movable shaft 23, the second fixed shaft 24 and the rotating shaft 25 are parallel, the movable shaft 23 is between the first fixed shaft 22 and the second fixed shaft 24, and can rotate up and down around the rotating shaft 25, the fulcrum structure 28 is fixed on the support frame 21, one end of the tensioning spring 27 is connected to the fulcrum structure 28, and the other end is connected to the movable shaft 23 to apply a pulling force to rotate downward to the movable shaft 23. The fulcrum structure 28 can be in the form of a nut and a screw, the tension spring 27 is connected to the screw, and the screw can move up and down along the nut to adjust the tension.

[0099] The tensioning mechanism 2 also includes a first photoelectric switch 211, a second photoelectric switch 212 and a third photoelectric switch 213 installed on the support frame 21, and a first triggering part 251 for triggering the first photoelectric switch 211, a second triggering part 252 for triggering the second photoelectric switch 212 and a third triggering part 253 for triggering the third photoelectric switch 213 are fixed on the rotating shaft 25. When the second triggering part 252 triggers the second photoelectric switch 212, the position of the movable shaft 23 is higher than the position of the movable shaft 23 when the first triggering part 251 triggers the first photoelectric switch 211, and is lower than the position of the movable shaft 23 when the third triggering part 253 triggers the third photoelectric switch 213.

[0100] During the operation of the tensioning mechanism 2, the flat copper wire passes through the first fixed shaft 22, the movable shaft 23 and the second fixed shaft 24 in sequence. The movable shaft 23 presses down the flat copper wire under the action of the tensioning spring 27 to play a tensioning role. When the flat copper wire is continuously pulled out of the tensioning mechanism 2 due to subsequent processing procedures, the movable shaft 23 will gradually rotate upward. In this way, through three photoelectric switches and three triggering parts, the wire-releasing step can be optimized to achieve periodic automatic wire-releasing. That is, the wire-releasing step specifically includes: when the third photoelectric switch 213 in the tensioning mechanism 2 is triggered by the third triggering part 253, the movable shaft 23 rotates to the highest position at this moment, indicating that the amount of copper wire stored in the tensioning mechanism 2 is insufficient, then the wire-releasing motor 1 is started, driving the copper wire shaft 11 to rotate to release the flat wire, until the second photoelectric switch 212 in the tensioning mechanism 2 is triggered by the second triggering part 252, and the wire-releasing stops. In addition, when the first photoelectric switch 211 in the tensioning mechanism 2 is triggered by the first triggering unit 251, the movable shaft 23 rotates to the lowest position at this moment, indicating that the flat copper wire is broken in the integrated machine and needs to be repaired.

[0101] The automatic paint stripping, soldering and winding integrated machine and process of this embodiment performs paint stripping process on flat copper wire through paint stripping device 3. Specifically, paint stripping device 3 includes laser marking machine 31 and limit seat 32, and limit seat 32 is provided with marking area 321 with open top, and head 311 of laser marking machine 31 is opposite to marking area 321 of limit seat 32 from above, and limit seat 32 is provided with first wire passing nozzle 322 and second wire passing nozzle 323 on both sides of marking area 321, and first wire passing nozzle 322 is provided with first limit passage 324 for passing flat copper wire, and second wire passing nozzle 323 is provided with second limit passage 325 for passing flat copper wire, and limit seat 32 receives flat copper wire from tensioning mechanism 2 through first wire passing nozzle 322, and transmits flat copper wire to soldering device 4 through second wire passing nozzle 323. The paint stripping device 3 stabilizes the flat copper wire through the first wire passing nozzle 322 and the second wire passing nozzle 323 to ensure the accuracy of the laser paint stripping process; the laser marking machine 31 can set multiple processing patterns and processing positions within its marking range (such as 170×170mm), so the laser marking machine 31 can strip paint at two positions of the flat copper wire each time, corresponding to the paint stripping positions (or soldering positions) of the two pins of the coil.

[0102] The automatic paint stripping, soldering and winding integrated machine and process of this embodiment performs a soldering process on the flat copper wire through the soldering device 4. Specifically, the soldering device 4 includes a soldering box 41 and a tin furnace 42. The soldering box 41 is used to receive the flat copper wire from the paint stripping device 3 and add soldering flux to the flat copper wire. The tin furnace 42 is used to receive the flat copper wire from the soldering box 41 and perform a soldering process on the flat copper wire. Among them, the insulating layer on the flat copper wire can refer to the insulating varnish used for the common enameled wire on the market, which has the characteristics of high temperature resistance and non-tin adhesion, that is, only the part of the flat copper wire where the insulating layer is removed by the paint stripping device 3 can be soldered, and the part with the insulating layer will not be attached to the tin liquid. Therefore, as long as the processing accuracy of the paint stripping device 3 can be guaranteed, the soldering device 4 can continuously perform the soldering process, and there is no need to issue a stop-start cycle processing instruction to the soldering device 4.

[0103] In the winding device 5 of the present embodiment, the automatic wire feeding assembly 52 includes a transverse linear module 521 and a wire feeding air clamp 522. The wire feeding air clamp 522 is installed on the slide seat of the transverse linear module 521. The transverse linear module 521 is used to drive the wire feeding air clamp 522 to reciprocate between the wire feeding nozzle 51 and the soldering device 4. The wire feeding air clamp 522 is used to pull the flat copper wire out of the soldering device 4 and feed it into the wire feeding nozzle 51. The driving direction of the transverse linear module 521 is parallel to the axial direction of the wire feeding nozzle 51; wherein, the transverse linear module 521 can be driven by a servo motor.

[0104] In the winding device 5, the winding upper mold assembly 54 and the winding lower mold assembly 55 can perform winding action on the flat copper wire to form a coil when they are closed; but because before winding, the flat copper wire has passed through the tensioning mechanism 2, the paint stripping device 3 and the soldering device 4 in sequence, these mechanisms or devices can give the flat copper wire a large resistance, and the flat copper wire has accumulated a relatively large length when passing through these mechanisms or devices, so the self-weight of the flat copper wire also adds a large resistance to the winding action, which makes it difficult for the winding upper mold assembly 54 and the winding lower mold assembly 55 to perform the winding action, and even unable to press and hang the flat copper wire, so an automatic wire feeding assembly 52 is configured in the winding device 5, which is used to continuously and cooperatively feed the wire during winding to solve the problem of excessive winding resistance.

[0105] In addition, since the flat copper wire has been tensioned, when the automatic wire feeding component 52 continuously pulls the flat copper wire out of the soldering device 4 and feeds it into the wire feeding nozzle 51, the wire pulling action of the automatic wire feeding component 52 will drive the flat copper wire to be continuously pulled out of the paint stripping device 3 and fed into the soldering device 4, and drive the flat copper wire to be continuously pulled out of the tensioning mechanism 2 and fed into the paint stripping device 3. Therefore, when the winding action is completed, the wire pulling action is completed synchronously at this time, so that the section of flat copper wire originally processed by the paint stripping device 3 / soldering device 4 is pulled out, and a new section of flat copper wire is fed into the paint stripping device 3 / soldering device 4, and the moving distance of the flat copper wire is precisely controlled (the moving distance = the wire feeding distance of the loading clamping component 53 + the wire feeding distance of the automatic wire feeding component 52), which makes the processing position or processing interval of the paint stripping device 3 also precisely controlled, which enables the present invention to well realize the coordination of paint stripping, soldering and winding processes, and thus can realize the integrated automatic production of paint stripping, soldering and winding.

[0106] In the winding device 5 of the present embodiment, its loading and clamping assembly 53 is used to pull the flat copper wire outward by a preset distance L, so that the wire end of the flat copper wire passes through the clamping position of the winding upper mold assembly 54 and the winding lower mold assembly 55, so that the wire end can form a pin of the coil after the winding action is completed; the shearing assembly 56 shears the flat copper wire, and its purpose is to separate the wound coil from the whole flat copper wire, and form another pin of the coil at the cutting point.

[0107] Specifically, the loading clamping assembly 53 includes an X-axis cylinder 531, a Y-axis cylinder 532 and a loading air clamp 533. The Y-axis cylinder 532 is installed on the movable seat of the X-axis cylinder 531, and the loading air clamp 533 is installed on the movable seat of the Y-axis cylinder 532. The driving direction of the X-axis cylinder 531 is parallel to the axial direction of the wire feeding nozzle 51; and it is obvious that the preset distance L is determined by the stroke of the X-axis cylinder 531.

[0108] Specifically, the shearing assembly 56 includes a transverse cylinder 561 and an air shear 562. The air shear 562 is installed on a movable seat of the transverse cylinder 561. The driving direction of the transverse cylinder 561 is parallel to the driving direction of the Y-axis cylinder 532. The feeding air clamp 533 and the air shear 562 are respectively located on both sides of the wire feeding nozzle 51 in the horizontal direction.

[0109] In the winding device 5 of the present embodiment, the winding upper die assembly 54 includes an X-axis linear module 541, a Y-axis linear module 542, a Z-axis linear module 543, an R-axis module 544 and a winding die head 545, the Y-axis linear module 542 is mounted on the slide of the X-axis linear module 541, the Z-axis linear module 543 is mounted on the slide of the Y-axis linear module 542, the R-axis module 544 is mounted on the slide of the Z-axis linear module 543, and the winding die head 545 is mounted on the output end of the R-axis module 544. The winding lower die assembly 55 includes a longitudinal linear module 551 and a winding lower die head 552, the winding lower die head 552 is mounted on the slide of the longitudinal linear module 551, and the longitudinal linear module 551 is used to drive the winding lower die head 552 to move up and down. Among them, these XYZR modules and longitudinal modules can be driven by servo motors.

[0110] Specifically, the winding line upper die head 552 is provided with a first mold closing hole 553 and a second mold closing hole 554, and the winding line die head 545 is provided with a winding center shaft 546 and a winding outer shaft (omitted in the drawings). In this embodiment, the mold closing (or mold closing position) of the winding line die assembly 54 and the winding line lower die assembly 55 refers to the mold closing (or mold closing position) of the winding line die head 545 and the winding line lower die head 552. When the winding line die head 545 and the winding line lower die head 552 are mold closed, the winding center shaft 546 is inserted into the first mold closing hole 553, and the winding outer shaft is inserted into the second mold closing hole 554. When the R-axis module 544 drives the winding line die head 545 to rotate, the winding outer shaft rotates around the winding center shaft 546 to realize the winding action.

[0111] Furthermore, the winding center shaft 546 includes a main shaft portion 5461 and a boss portion 5462 fixed to the main shaft portion 5461, the diameter of the boss portion 5462 is slightly larger than the diameter of the main shaft portion 5461, and thus the R-axis module 544 can carry the sheared and separated coil to move; the winding center shaft 546 extends from the bottom end of the winding die 545, and the R-axis module 544 is provided with a telescopic cylinder 547, and the output end of the telescopic cylinder 547 is connected to the winding center shaft 546. The winding center shaft 546 can be telescopic relative to the winding die 545 under the action of the telescopic cylinder 547. When the winding center shaft 546 shrinks, the coil wrapped around the winding center shaft 546 will be squeezed and fall out.

[0112] If the coil pins need to be bent (some types of coils need to be bent, and some types do not), a bending assembly 57 can be added to the winding device 5. The bending assembly 57 includes a bending cylinder 571, a bending die 572, and a bending fixed die 573. The bending die 572 is installed on the moving seat of the bending cylinder 571. The top of the bending fixed die 573 is provided with a positioning groove 574 for placing the coil. The bending fixed die 573 is provided with a longitudinally extending pin limiting groove 575 on the side facing the bending die 572. The pin limiting groove 575 and the positioning groove 574 together form an L-shaped groove structure. In this way, the winding step of the process of this embodiment also includes a winding sub-step ⑤: the winding upper die assembly 54 carries the coil to the positioning groove 574 of the bending fixed die 573, and the bending cylinder 571 drives the bending die 572 to bend the two pins of the coil.

[0113] The unloading assembly 6 of this embodiment includes an unloading channel 61 and an unloading box 62. One end of the unloading channel 61 is opened upward, and the other end of the unloading channel 61 is opened toward the unloading box 62. Specifically, the unloading step includes: the winding upper mold assembly 54 carries the coil and moves to the top of the unloading channel 61, and the coil is squeezed to fall into the unloading channel 61, and then is stored in the unloading box 62.

[0114] In summary, the automatic paint stripping, soldering and winding integrated machine and process of this embodiment can realize the integrated automatic production of paint stripping, soldering, winding and other processes of the flat copper coil of the inductor, thereby reducing labor costs and improving production efficiency.
