Description

Technical Field

[0001] This utility model relates to the field of transformer processing, specifically to a multi-wire, multi-tube, single-axis winding machine. Background Technology

[0002] Transformers, especially small transformers, require operations such as pipe feeding, wire feeding, and pipe threading during production. This involves cutting flexible bushings to the target length, threading wires through the two cut sections of bushing, and then wrapping the threaded wires around the transformer's pins and frame. At this point, the bushing is located between the pins and the frame.

[0003] Currently, the winding machines on the market are basically of two types: single-arm single-wire double-tube winding machines and double-arm sleeve winding machines. For products with complex processes, multiple single-arm single-wire double-tube winding machines or one double-arm sleeve winding machine are required for processing. Multiple single-arm single-wire double-tube winding machines are more expensive and less efficient, while one double-arm sleeve winding machine is more efficient, but the cost is still higher.

[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0037] The working principle and advantages of this utility model are as follows:

[0038] The overall cost of this utility model is lower than that of equipment with the same function on the market; for the same product that requires double-wire sleeve process, this utility model can complete the process with one machine, while the current technology and equipment on the market require two single-arm single-wire double-tube winding machines or one double-arm sleeve winding machine to complete the processing.

[0039] The cost of this multi-wire, multi-tube, single-arm winding machine is higher than that of the single-arm, single-wire, double-tube winding machines currently on the market. However, for products with complex processes, a single multi-wire, multi-tube, single-arm winding machine can complete the processing, resulting in a significantly lower overall equipment investment cost compared to the single-arm, single-wire, double-tube machines currently available. Compared to the double-arm sleeve winding machines currently on the market, this invention reduces the number of winding arm assemblies by one set, further lowering the cost.

[0040] The present invention shortens the working distance of the Z-axis winding fixture between the A1 and A2 axes and the flat stretching and coating mechanism, thereby improving the overall working efficiency of the machine. Currently, the overall efficiency of the machine based on this technology is 20% higher than that of similar products on the market.

[0041] This invention allows the winding machine to not only wind wires of various diameters and achieve double or multiple wire winding by adjusting the pin spacing of multiple wire feeding guides and multiple wire passing guides, but also to adapt to winding pins with different spacings for different sized frames.

[0042] The wire feeding and tube feeding mechanism of this utility model has a compact structure. The three-wire feeding uses three wire feeding wheels arranged in a triangular pattern, which can maximize the adjustment of the center distance of the three wire feeding wheels, making it easy to adjust the needle spacing between the guide pins and suitable for winding wires with different spacings of pins. In addition, the center distance between the wire feeding wheels can also be adjusted, which can better adapt to and position guide wires with different wire spacings.

[0043] The wire-cutting mechanism of this invention is simple and practical, and the two pneumatic shears can handle a variety of complex processes and products. Attached Figure Description

[0065] The present invention will be further described below with reference to the accompanying drawings and embodiments:

Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0067] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0068] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0069] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0070] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0071] See appendix Figure 1-11 As shown, a multi-wire, multi-tube, single-axis winding machine includes a machine base 100, on which a wire feeding and tube-threading unit 200, a winding and foot-winding unit 300, a flat-pull coating unit 400, and a skeleton feeding unit 500 are provided.

[0072] See appendix Figure 1-5 As shown, the wire feeding and threading unit 200 includes a tube feeding mechanism 2 for feeding the sleeve, a wire feeding mechanism 1 for feeding the wire, a sleeve clamping module 3 for cutting and clamping the sleeve, and a tube clamping module 5 for clamping the cut and threaded sleeve; the sleeve clamping module 3 is driven to switch between the tube feeding station on the output side of the tube feeding mechanism 2 and the threading station on the output side of the wire feeding mechanism 1.

[0073] The wire feeding direction is left and right. The tube feeding mechanism 2 and the wire feeding mechanism 1 are arranged side by side, with the tube feeding mechanism 2 located on the front side and the wire feeding mechanism 1 located on the rear side.

[0074] In this embodiment, the wire feeding mechanism 1 includes at least one set of wire feeding wheel groups 11 distributed along the direction perpendicular to the wire feeding direction, and each set of wire feeding wheel groups 11 has a wire feeding guide pin 12 corresponding to the input side and the output side.

[0075] The wire feeding wheel assembly 11 includes a wire feeding wheel 111 and a wire pressing wheel 112 distributed vertically. The wire feeding wheel 111 is driven linearly to approach or move away from the wire pressing wheel 112 to clamp or release the wire. The wire feeding wheel 111 is driven to rotate to transport the wire.

[0076] During wire feeding, a set of wire feeding wheels 11 and the wire feeding guide pins 12 on both sides constitute a wire feeding system. Specifically, the wire is introduced through the wire feeding guide pin 12 on the input side, passes through the wire feeding wheel set 11, and is finally output from the wire feeding guide pin 12 on the output side. The transmission of the wire is driven by the rotating wire feeding wheels 111.

[0077] When the wire feeding wheel group 11 is set up as a group, it constitutes a wire feeding system that can transport one wire (not shown in the figure).

[0078] When the wire feeding wheel sets 11 are arranged in two sets, the two sets of wire feeding wheel sets 11 can be arranged side by side or staggered front and back. At this time, two side-by-side wire feeding systems are formed, capable of conveying two paths of wires, and each path of wire can be at least one (not shown in the figure).

[0079] When the wire feeding wheel sets 11 are arranged in three sets, the three sets of wire feeding wheel sets 11 can be arranged in a "pin" shape (see Figure 4 ) or side by side (not shown in the figure). At this time, three side-by-side wire feeding systems are formed, capable of conveying three paths of wires, and each path of wire can be at least one. This embodiment can wind wires of three wire diameters and can realize double-wire or multi-wire parallel winding.

[0080] In this embodiment, when the three sets of wire feeding wheel sets 11 are arranged in a "pin" shape, two sets of wire feeding wheel sets 11 are arranged side by side, and the third set of wire feeding wheel set 11 is arranged in front of or behind the two side-by-side wire feeding wheel sets 11 and is located on the symmetry axis of the two sets of wire feeding wheel sets 11. The two side-by-side wire feeding wheels 111 can be coaxially arranged or separately arranged on different axes. The wire feeding wheel 111 is connected to the driving shaft 115. The driving shafts 115 of the three wire feeding wheels 111 can be driven by synchronous belt wheels or separately driven by motors. The two side-by-side wire pressing wheels 112 are coaxially arranged, and the two wire pressing wheels 112 can be separately arranged or integrally arranged. When integrally arranged, it can save space.

[0081] In this embodiment, the support structure of the wire feeding wheel 111 is linearly driven by the wire feeding pressing cylinder 118 to press against the wire pressing wheel 112 to press the wire after the wire threading is completed.

[0082] In this embodiment, a wire passing guiding bracket 19 is further arranged on the input side of the left wire feeding guide pin 12. A guiding hole for passing through the wire is opened on the wire passing guiding bracket 19. A tension controller is correspondingly arranged on the input side of the wire passing guiding bracket 19, and a wire pressing cylinder 20 for pressing the wire is arranged on the output side. See Figure 4-5 .

[0083] In this embodiment, when winding wires on multiple pin feet of a transformer skeleton simultaneously, the wire feeding system is set to more than one, and the specific quantity is determined according to the number of wire paths. At this time, the wire feeding guide pins 12 are arranged in more than one in the direction perpendicular to the wire feeding direction, that is, both the wire feeding guide pins 12 on the input side and the output side are arranged in two or more. In addition, for skeletons of different sizes, the pin foot spacings are different. To adapt to the pin feet with different spacings, a wire feeding guide pin pitch adjusting structure for adjusting the pitch of each of the wire feeding guide pins 12 on the same side is further included.

[0084] As Figure 6-7As shown, the wire feeding guide pin distance adjusting structure includes a wire feeding guide pin mounting plate 13 for mounting and adjusting the wire feeding guide pin 12, and the wire feeding guide pin mounting plate 13 is fixed on the main frame. A first waist-shaped hole a14 is formed through both side walls of the wire feeding guide pin mounting plate 13, and the length direction of the first waist-shaped hole a14 is perpendicular to the wire feeding direction. Each wire feeding guide pin 12 arranged on the same side passes through the first waist-shaped hole a14 and can move along the length direction of the first waist-shaped hole a14;

[0085] The wire feeding guide pin distance adjusting structure further includes wire feeding guide pin fasteners corresponding to and fixed to each wire feeding guide pin 12, and the wire feeding guide pin fasteners are fixedly connected to the wire feeding guide pin mounting plate 13 through wire feeding guide pin fastening screws 18.

[0086] The wire feeding guide pin fastener includes a wire feeding guide pin fixing block 15, and a second waist-shaped hole a16 is formed through the wire feeding guide pin fixing block 15. A threaded hole a17 is provided on the wire feeding guide pin mounting plate 13 corresponding to the second waist-shaped hole a16, and the wire feeding guide pin fastening screw 18 passes through the second waist-shaped hole a16 and is threadedly connected to the threaded hole a17.

[0087] When adjusting the wire feeding guide pin 12, loosen the wire feeding guide pin fastening screw 18, move the wire feeding guide pin fixing block 15, so that the wire feeding guide pin 12 fixed thereon moves within the first waist-shaped hole a14. After moving in place, tighten the wire feeding guide pin fastening screw 18 so that its head tightly presses the wire feeding guide pin fixing block 15 against the wire feeding guide pin mounting plate 13. By adjusting the distance between the wire feeding guide pins 12, that is, adjusting the wire distance, it can adapt to pin feet with different distances.

[0088] In other embodiments, the wire feeding guide pin 12 can also be fixed on different specification blocks, and the specification blocks are detachably mounted on the wire feeding guide pin mounting plate 13 through screws or the like. The distances between the wire feeding guide pins 12 on different specification blocks are different. When it is necessary to adjust the wire distance, only need to replace the specification block with the corresponding wire distance.

[0089] When adjusting the above-mentioned wire feeding guide pin 12, the three wire feeding wheel groups 11 are distributed in a "pin" shape, and the center distance between the three wire feeding wheels 111 can be minimized, that is, the distance between the three wires can be adjusted to be smaller.

[0090] To better position the wire, the wheel surface of the wire feeding wheel 111 is concave to form an annular groove for positioning the wire, but this annular groove will affect the wire distance adjustment. Regarding this, as Figure 8As shown, the wire feeding mechanism 1 further includes a wire feeding wheel adjustment structure for adjusting the center distance of each of the wire feeding wheels 111. The wheel surface width of the pressure wheel 112 is greater than the wheel surface width of the wire feeding wheel 111. The wire feeding wheel adjustment structure includes a bushing 113. The wire feeding wheel 111 is fixedly sleeved on the outer wall of the bushing 113. The bushing 113 is fixedly connected to the drive shaft 115 of the wire feeding wheel 111 by a locking member.

[0091] In this embodiment, the locking component can be a locking screw 114. A third oblong hole 116 is provided on the bushing 113 along the axial direction. A screw hole 117 is provided on the drive shaft 115 corresponding to the third oblong hole 116. The locking screw 114 passes through the third oblong hole 116 and is threadedly connected to the screw hole 117.

[0092] When it is necessary to adjust the wire spacing, in addition to adjusting the spacing of the wire feeding pins 12, this embodiment also adjusts the center distance of the three wire feeding wheels 111 so that the annular groove can be adjusted according to the wire spacing. The specific adjustment method is as follows: loosen the locking screw 114, move the wire feeding wheel 111, and move the third oblong hole 116 on the bushing 113 relative to the locking screw 114. After it is moved into place, tighten the locking screw 114. The head of the locking screw 114 presses against the outer wall of the bushing 113, thereby fixing the bushing 113 to the drive shaft 115. When the drive shaft 115 rotates, it drives the wire feeding wheel 111 to rotate to feed the wire.

[0093] In order to cooperate with the moving wire feeding wheel 111 and thus stably support the wire, the width of the wheel surface of the pressing wheel 112 is greater than the width of the wheel surface of the wire feeding wheel 111, so that the wire feeding wheel 111 can be moved.

[0094] In this embodiment, the tube feeding mechanism 2 includes at least one set of tube feeding wheel group 21, and tube feeding guide needles 22 are provided on both the input side and the output side of the tube feeding wheel group 21.

[0095] The tube feeding wheel assembly 21 includes a tube feeding wheel 211 and a tube pressing wheel 212 distributed vertically. The tube feeding wheel 211 is driven linearly to approach or move away from the tube pressing wheel 212 to clamp or release the sleeve. The tube feeding wheel 211 is driven to rotate to deliver the sleeve.

[0096] During tube feeding, a set of tube feeding wheels 21 and the tube feeding guide pins 22 on both sides constitute a tube feeding system. Specifically, the sleeve is introduced through the tube feeding guide pin 22 on the input side, passes through the tube feeding wheel set 21, and is finally output from the tube feeding guide pin 22 on the output side. The transmission of the wire is driven by the rotating tube feeding wheel 211.

[0097] When the pipe delivery wheel group 21 is set up as a group, it constitutes a pipe delivery system, which can deliver one pipe (not shown in the figure).

[0098] When the pipe feeding wheel set 21 is configured as two sets, the two sets of pipe feeding wheel sets 21 can be distributed side by side, thus forming two parallel pipe feeding systems capable of conveying two pipes, see [link to relevant documentation]. Figure 1-5 .

[0099] In this embodiment, the rotating shaft of the tube feeding wheel 211 is connected to a motor, and the support structure of the tube feeding wheel 211 is linearly driven by the tube feeding clamping cylinder 213 to press against the tube clamping wheel 212 so as to press the sleeve after the tube is inserted.

[0100] In this embodiment, a tube guide 23 is also provided on the input side of the left tube guide needle 22. The tube guide 23 has a guide hole for penetrating the sleeve. A sleeve disc is correspondingly provided on the input side of the tube guide 23, and a tube pressing cylinder 24 for the sleeve is provided on the output side. (See...) Figure 4-5 .

[0101] In this embodiment, as Figure 3 As shown, the sleeve clamp module 3 includes a cutting assembly 31 for cutting the sleeve and a sleeve clamp assembly 32 for clamping the cut sleeve. The sleeve clamp assembly 32 is located behind the cutting assembly 31. The sleeve clamp assembly 32 is driven by a screw motor 33 to move linearly between the pipe feeding station and the threading station. The sleeve clamp assembly 32 can be the type shown in application number CN202222610730.6. The cutting assembly 31 includes a cutting blade, which is driven up and down by a cutting cylinder to cut the sleeve. Alternatively, the sleeve clamp assembly 32 can also be driven by a linear module 36 to move linearly between the pipe feeding station and the threading station. Using this linear module 36 to install the sleeve clamp assembly 32 can improve the stability of pipe clamping and feeding. See Figure 11 .

[0102] The sleeve clamp module 3 further includes a sleeve expander 34, which is driven by an expanding cylinder 35 to move toward the sleeve in the first clamping groove to expand the hole at the sleeve inlet end. Figure 3 .

[0103] Each of the first clamping slots of the sleeve clamp assembly 32 entering the threading station corresponds one-to-one with the thread guide pins 43 on the two thread guide shafts.

[0104] In this embodiment, as Figure 3 As shown, the tube clamping module 5 is located at the outlet of the wire feeding guide pin 12 on the output side. The tube clamping module 5 includes a tube clamping fixture 51 for clamping the sleeve after it has been cut by the tube cutting assembly 31, and a tube clamping cylinder 52 for driving the tube clamping fixture 51 to open and close. When the tube clamping fixture 51 is closed, its second tube clamping groove corresponds one-to-one with each of the wire feeding guide pins 12 on the output side.

[0105] See appendix Figure 1-2 and Figure 9-10 As shown, the winding unit 300 includes a dual-axis winding mechanism 4, a wire cutting mechanism 6, and a winding mechanism 7.

[0106] Among them, such as Figure 9 As shown, the dual-axis winding mechanism 4 includes two wire guide shafts respectively located at the beginning and end of the threading station, a rotary module for driving the two wire guide shafts to rotate, and a linear drive module for driving the two wire guide shafts to move linearly along the wire feeding direction. The entire dual-axis winding mechanism 4 is equivalent to a single arm. The opposing surfaces of the two wire guide shafts are provided with wire guide pins 43 for passing wires. The first wire guide shaft 41 is located at the beginning of the threading station, and the second wire guide shaft 42 is located at the end of the threading station. A wire clamping assembly 44 is also provided on the side wall of the second wire guide shaft 42 away from the wire guide pins 43.

[0107] The wire guide pin 43 corresponds one-to-one with the wire feed guide pin 12 along the wire feed direction. In order to keep them collinear, when the wire feed guide pin 12 and the wire guide pin 43 are arranged in more than one direction perpendicular to the wire feed direction, a wire guide pin spacing adjustment structure is also included for adjusting the spacing between the wire guide pins 43 on the same side. The wire guide pin spacing adjustment structure is the same as the wire feed guide pin spacing adjustment structure.

[0108] The wire guide pin spacing adjustment structure includes a wire guide pin mounting plate for installing and adjusting the wire guide pin 43. The wire guide pin mounting plate is integrally formed with the wire guide shaft to which it is located. A first waist-shaped hole b is formed through its two side walls on the wire guide pin mounting plate. The length direction of the first waist-shaped hole b is perpendicular to the wire feeding direction. Each wire guide pin 43 arranged on the same side passes through the first waist-shaped hole b and can move along the length direction of the first waist-shaped hole b.

[0109] The wire guide pin spacing adjustment structure also includes wire guide pin fasteners that correspond one-to-one with and are fixed to each wire guide pin 43. The wire guide pin fasteners are fixedly connected to the wire guide pin mounting plate by wire guide pin fastening screws.

[0110] The wire guide pin fastener includes a wire guide pin fixing block, on which a second oblong hole b is formed. The wire guide pin mounting plate corresponding to the second oblong hole b is provided with a threaded hole b. The wire guide pin fastening screw passes through the second oblong hole b and is threadedly connected to the threaded hole b.

[0111] When adjusting the guide pin 43, loosen the guide pin fastening screw, move the guide pin fixing block so that the guide pin 43 fixed on it moves into the first oblong hole b. After it moves into place, tighten the guide pin fastening screw so that the screw head presses the guide pin fixing block tightly against the guide pin mounting plate.

[0112] In other embodiments, the wire guide pins 43 can also be fixed on different specification blocks. The specification blocks are detachably mounted on the two wire guide spools by screws or the like. The spacing of the wire guide pins 43 on different specification blocks is different. When it is necessary to adjust the wire spacing, it is only necessary to replace the specification block with the corresponding wire spacing.

[0113] To improve threading accuracy, the outlet end of the thread feeding guide 12 on the output side and the inlet end of the threading guide on the first threading shaft 41 at the beginning of the threading station are configured as a trumpet shape that can be interlocked.

[0114] In this embodiment, as Figure 9 As shown, the wire clamping assembly 44 includes a wire clamping seat 441, a wire clamping block 442, and a wire clamping cylinder 443. The wire clamping seat 441 and the wire clamping cylinder 443 are fixed to the second wire guide spool 42. The wire clamping cylinder 443 drives the wire clamping block 442 to move closer to or away from the wire clamping seat 441 to clamp or release the wire.

[0115] In this embodiment, as Figure 9 As shown, the rotating module includes two servo motors 45, which are respectively fixed on two support frames 46. The guide shaft passes through the support frame 46 and is connected to the servo motors 45. The linear drive module includes two moving cylinders 47, which are respectively fixedly connected to the two support frames 46. Both support frames 46 slide with two slide rails 49 on the machine base 100 via sliding feet 48 on both sides of their bottom. Through the above design, the two sliding feet 48 of the support frames 46 at the bottom of the two guide shafts share two slide rails 49, which can improve the movement stability of the two guide shafts. In addition, the two moving cylinders 47 can be set on the same side, reducing space occupation.

[0116] In this embodiment, as Figure 10 As shown, the wire cutting mechanism 6 includes a wire cutting module for cutting wires, which is driven to move in and out of the threading station. In this embodiment, the wire cutting module includes two pneumatic scissors arranged side by side, one high and one low. The lower one is the first pneumatic scissor 61, and the higher one is the second pneumatic scissor 62. The two pneumatic scissors are respectively positioned on two guide rails, and are driven to move in and out of the threading station by a push cylinder 63. The two pneumatic scissors are slidably mounted on two guide rails 64, which are fixed to a bracket, which is fixed to the first table 101. The wire cutting mechanism 6 has a simple and practical structure, and the two pneumatic scissors can handle a variety of complex processes.

[0117] The winding mechanism 7 includes a rotatable skeleton clamping component 71 that moves along the X, Y, and Z axes. In this embodiment, the skeleton clamping component 71 is driven by a three-axis platform 72. During winding, the skeleton clamping component 71 clamps the transformer skeleton and moves in and out of the threading station.

[0118] In this embodiment, as Figure 2 As shown, the wire cutting mechanism 6 and the wire winding mechanism 7 are arranged opposite each other and are both perpendicular to the wire feeding direction. In this embodiment, the wire feeding direction is left-right. The wire cutting mechanism 6 is located on the front side, and the wire winding mechanism 7 is located on the rear side, both corresponding to the threading station. The wire winding mechanism 7 is located beside the flat stretching and coating unit 400 and the skeleton feeding unit 500. The skeleton feeding unit 500 includes a loading mechanism and a unloading mechanism. The loading mechanism is located on the left side of the wire winding mechanism 7, and the unloading mechanism and the flat stretching and coating unit 400 are located on the right side of the wire winding mechanism 7, with the unloading mechanism located behind the flat stretching and coating unit 400. This spatial arrangement facilitates the loading, unloading, coating, and winding of the wire winding mechanism 7, prevents interference between the mechanisms, ensures a smooth working cycle, and increases processing efficiency.

[0119] In this embodiment, the flat-pull coating unit 400 can be a flat-pull coating device for a transformer as shown in application number CN202320455834.6.

[0120] In this embodiment, as Figure 1-2 As shown, the upper surface of the machine base 100 includes a first table 101 and a second table 102, which are arranged at different heights to form a stepped surface. The height of the first table 101 is higher than that of the second table 102. The wire feeding and tube threading unit 200, the dual-axis winding mechanism 4, and the wire cutting mechanism 6 are disposed on the first table 101. The winding mechanism 7, the flat pulling and coating unit 400, and the skeleton feeding unit 500 are disposed on the second table 102. By setting the table heights, the working travel distance of the winding mechanism 7 between the two wire guides and the flat pulling and coating unit 400 is shortened, thereby improving the overall working efficiency of the machine. Currently, the overall efficiency of the machine using this technology is 20% higher than that of similar products on the market.

[0121] The winding process of the product using the single-axis winding machine of this implementation is as follows:

[0122] 1. Wire threading preparation: The wire is output from the tension controller and passes through the wire guide bracket 19 → left wire feeding guide pin 12 → between the wire feeding wheel 111 and the pressure wheel 112 → right wire feeding guide pin 12. The wire is pressed by the pressure cylinder 20 after the threading is completed.

[0123] 2. Sleeve insertion preparation: The sleeve is output from the sleeve plate through the sleeve support 23 → left side tube guide needle 22 → between tube feed wheel 211 and tube pressure wheel 212 → right side tube feed guide needle 22. After the sleeve insertion is completed, the sleeve is pressed by the tube pressure cylinder 24.

[0124] 3. Pipe insertion:

[0125] a. The lead screw motor 33 pushes the sleeve clamp assembly 32 to move and aligns the inlet of the first clamping groove with the feeding nozzle of the right-side feeding guide needle 22. The feeding clamping cylinder 213 presses the sleeve onto the feeding wheel 211. The clamping cylinder 24 releases the sleeve. The feeding wheel 211 rotates to feed the sleeve into the sleeve clamp according to the process length and number of segments. After the feeding length meets the process requirements, the feeding wheel 211 stops rotating to feed the sleeve. The cutting cylinder pushes the cutting blade to cut the sleeve. When the feeding length and number of segments both meet the process requirements, the clamping cylinder 24 starts to press the sleeve. At the same time, the feeding clamping cylinder 213 closes and drives the feeding wheel 211 to lift up, and the threading step begins.

[0126] b. The lead screw motor 33 pushes the sleeve clamp assembly 32 to move, so that the inlet of the first clamp groove containing the sleeve is aligned with the sleeve expander 34. The expanding cylinder 35 pushes the sleeve expander 34 to expand the hole at the inlet end of the sleeve. After the expanding is completed, the threading step begins.

[0127] 4. Threading:

[0128] a. The moving cylinder 47 drives the first wire guide shaft 41 and its wire guide pin 43 to move to the output end of the right-side wire feeding guide pin 12, and places the input end of the wire guide pin 43 against the output end of the wire feeding guide pin 12; the lead screw motor 33 pushes the sleeve clamp assembly 32 to move between the wire guide pin 43 of the first wire guide shaft 41 and the wire guide pin 43 of the second wire guide shaft 42, and aligns the inlet of the first clamp groove with the output end of the wire guide pin 43; the moving cylinder 47 drives the second wire guide shaft 42 and its wire guide pin 43 to move to the output end of the sleeve clamp assembly 32, and places the input end of the wire guide pin 43 against the outlet of the first clamp groove. At this time, the centers of the holes of the wire feeding guide pins 12 on the left and right sides, the sleeve clamp, and the wire guide pins 43 on the two wire guide shafts must be kept in a straight line to ensure smooth wire threading.

[0129] b. Release the wire pressing cylinder 20 and simultaneously activate the wire feeding and clamping cylinder 118, pushing the wire feeding wheel 111 to press the wire onto the wire pressing wheel 112. The wire feeding wheel 111 rotates, feeding the wire out, through the wire guide pin 43 of the first wire guide shaft 41, the inner sleeve of the sleeve clamp assembly 32, and the wire guide pin 43 of the second wire guide shaft 42, leaving the front end of the wire between the wire pressing seat 441 and the wire clamping block 442. The wire clamping cylinder 443 pushes the wire clamping block 442 to clamp the wire.

[0130] c. After steps a and b above are completed, thread the wire harness. After threading the wire harness, the wire feeding and clamping cylinder 118 is closed, and the wire feeding wheel 111 is raised. The dual-axis winding mechanism 4 is ready for winding.

[0131] 5. Winding:

[0132] a. The sleeve clamp assembly 32 loosens the sleeve, and then, driven by the lead screw motor, retracts to the output end of the right-side tube feeding guide pin 22, aligning the first clamping groove with the output end of the tube feeding guide pin 22.

[0133] b. If both the starting and ending ends require sleeves, after completing step a above, the sleeve clamping cylinder 52 drives the sleeve clamping fixture 51 to clamp the sleeve near the wire guide pin 43 on the first wire guide spool 41, but does not clamp the wire passing through this sleeve.

[0134] c. The moving cylinder 47 drives the second wire guide 42 to the working position, and at the same time the wire is pulled out. The unclamped sleeve moves to the working position of the second wire guide 42 along with the wire guide pin 43 on the second wire guide 42.

[0135] d. As the second guide spindle 42 moves to the working position, the Z-axis of the three-axis platform 72 drives the skeleton clamping assembly 71 to pick up the product skeleton, then moves it between the first guide spindle 41 and the second guide spindle 42, and places the wire at the starting winding position, then moves it to the right side of the guide pin seat of the second guide spindle 42 (near the three-axis platform 72); at the same time, the servo motor 45 of the second guide spindle 42 rotates clockwise, so that the guide pin 43 of the second guide spindle 42 is perpendicular to the PIN face of the product skeleton; the three-axis platform 72... The 72Z axis of the platform drives the product skeleton to perform a winding action. After the winding action is completed, the wire clamping cylinder 443 drives the wire clamping block 442 to release the wire. The three-axis platform 72Z axis drives the product skeleton to move along the X-axis towards the first wire guide axis 41 while performing a circumferential winding action according to the process requirements. When the skeleton moves to the alignment of the first pneumatic shears 61, the movement and circumferential winding action of the product skeleton stop. The first pneumatic shears 61 is pushed out by the push cylinder 63 to cut off the excess wire on the starting pin and then retracts. The three-axis platform 72Z axis drives the product skeleton to continue moving along the X axis towards the first wire guide axis 41 and continues to perform a circumferential rotation and winding action according to the process requirements until it moves to the side where the wire guide pin 43 of the first wire guide axis 41 faces the three-axis platform 72. The wire guide pin 43 of the first wire guide axis 41 turns to the side of the product skeleton, and the three-axis platform 72Z axis drives the product skeleton to perform a groove winding action. After the winding action is completed, the three-axis platform 72Z axis drives the product skeleton to the alignment position of the first pneumatic scissors 61 or the second pneumatic scissors 62. The push cylinder 63 pushes out the first pneumatic scissors 61 or the second pneumatic scissors 62 to cut the wire close to the take-up pin. Then, the three-axis platform 72Z axis drives the product skeleton to the flat pull coating mechanism to complete the coating operation. At this time, the wire is retracted to the right wire feeding guide pin 12 under the action of the tension controller, and the wire pressing cylinder 20 presses the wire to hold it, waiting for the next wire feeding operation.

[0136] e. Once the overmolding is completed, the product winding process is finished.
