Description
Technical Field
[0001] The present invention relates to the technical field of automatic production of electric components, and in particular to an electric component production device. Background Art
[0002] Many electrical components have coils, such as wound inductors, wound resistors, mutual inductors, various rotors, etc. During the production process of such electrical components, the wires need to be neatly wound around the magnetic core in circles to form coils. The coils need to fit tightly together, and there cannot be loose arrangements with large gaps between them, or stacking of a single wire on top of or under other parts. In the prior art, this is done using an automatic winding machine.
[0003] For example, the patent with publication number CN114334438B and publication date of August 26, 2022 discloses a fully automatic transformer magnetic ring winding machine, including a feeding mechanism, a conveying mechanism, a wire pulling mechanism, a winding mechanism and a tail wire collecting mechanism located on a workbench, wherein the feeding mechanism is located at the rear side of the winding mechanism, the feeding mechanism is tilted between the feeding mechanism and the winding mechanism, the wire pulling mechanism is located on one side of the winding mechanism and in front of the conveying mechanism, and the tail wire collecting mechanism is located in front of the winding mechanism. This patent adopts the above-mentioned fully automatic transformer magnetic ring winding machine, so that the copper wire is evenly wound on the magnetic ring, without a large amount of manpower, and the wound magnetic ring product has a high yield rate, which can meet continuous and stable quality production.
[0004] When an existing winding machine is performing a winding process, the winding speed of the winding machine and the moving speed of the magnetic core are kept constant. When the number of winding layers of the copper wire on the surface of the magnetic core increases, the required winding length of the copper wire on the surface of the magnetic core also increases accordingly, and then the time required for the winding machine to wind one circle at a constant speed increases. If the magnetic core still moves at a constant speed, the winding speed of the copper wire on the outer ring of the magnetic core cannot keep up with the feed speed of the magnetic core, and the copper wire on the surface of the magnetic core is prone to loose arrangement, affecting the winding quality of the copper wire on the surface of the magnetic core.

DETAILED DESCRIPTION
[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 - Attachment Fig. 9 , the present invention is further introduced in detail.
[0031] An electrical device production device provided by an embodiment of the present invention includes a supporting mechanism 2 for placing a magnetic core 1 and a winding mechanism 3 for winding the magnetic core 1. The magnetic core 1 is annular in shape and is preferably arranged horizontally. The supporting mechanism 2 includes a driving part 21, and the driving part 21 includes a driving motor and a plurality of vertically placed vertical rods 211. The driving motor is fixed on a base. A placement block 212 is installed on each of the plurality of vertical rods 211. The plurality of placement blocks 212 clamp the outer wall of the magnetic core 1 to drive the magnetic core 1 to rotate in a horizontal direction. The supporting mechanism 2 also includes a reducing part 22, an adjusting part 23 and a speed regulating part 24 connected in sequence. The reducing part 22 abuts against the surface of the magnetic core 1, and the speed regulating part 24 is connected to the driving part 21. When the number of copper wire winding layers on the surface of the magnetic core 1 increases, the reducing part 22 will be squeezed to move away from the magnetic core 1 in a vertical direction. At the same time, the reducing part 22 drives the adjusting part 23 to move, and the adjusting part 23 adjusts the speed regulating part 24 to slow down the horizontal rotation speed of the driving part 21 to drive the magnetic core 1.
[0032] Specifically, the electrical device production apparatus in the prior art includes two parts: a bearing mechanism 2 and a winding mechanism 3. The bearing mechanism 2 is used to limit the bearing and drive the magnetic core 1, and the winding mechanism 3 is used to wind the magnetic core 1. The embodiments of the present invention only improve the bearing mechanism 2, and the improvement does not require the winding mechanism 3 to make adaptive improvements. Based on this, the embodiments of the present invention only discuss the bearing mechanism 2 in detail. Because the winding mechanism 3 can be existing, it will not be repeated below. The adjusting portion 23 includes a fixed plate 231, which is fixedly connected to the reducing portion 22. A second rotating shaft 232 is fixedly mounted on the fixed plate 231, and a rotating rod 233 is rotatably mounted on the second rotating shaft 232. One end of the rotating rod 233 passes through the connecting groove 25 and is connected to the sliding rod 222, and the other end of the rotating rod 233 is connected to the speed regulating portion 24. The speed regulating portion 24 has multiple gears, and the multiple gears correspond to different speeds. As the number of copper wire layers on the surface of the magnetic core 1 increases, the top height gradually increases, thereby gradually lifting one end of the rotating rod 233. Driven by the movement of the rotating rod 233, the speed regulating portion 24 switches from a high-speed gear to a low-speed gear.
[0033] The second friction table 242 in the speed regulating part 24 is connected to one of the vertical rods 211 and arranged coaxially, and the output shaft of the driving motor is connected to the first friction table 241 in the speed regulating part 24 and arranged coaxially.
[0034] In this embodiment, the speed regulating part 24 includes two centrally symmetrical first friction tables 241 and second friction tables 242, the adjacent sides of the first friction tables 241 and the second friction tables 242 are parallel, an adjusting gear handle 243 is arranged between the first friction tables 241 and the second friction tables 242, and an intermediate wheel 244 is coaxially mounted on the adjusting gear handle 243, and the side surfaces of the intermediate wheel 244 are respectively abutted against the surfaces of the first friction tables 241 and the second friction tables 242. Preferably, the first friction table 241 is connected to the driving part 21 and is coaxially arranged, and the second friction table 242 is connected to one of the vertical rods 211 and is coaxially arranged. In the initial state, the intermediate wheel 244 is in contact with the maximum radius of the first friction table 241 and the minimum radius of the second friction table 242, respectively, and at this time, the intermediate wheel 244 is in contact with the second friction table 2 The vertical rod 211 connected to 42 is in the maximum speed state, that is, the speed of the magnetic core 1 is the fastest at this time. As the number of copper wire layers on the surface of the magnetic core 1 increases, under the action of the diameter-changing part 22 and the adjusting part 23, the adjusting part 23 drives the adjusting lever 243 to move, thereby changing the contact position of the intermediate wheel 244 with the first friction table 241 and the second friction table 242 (the intermediate wheel 244 moves along the side of the first friction table 241 from the maximum radius of the first friction table 241 to the minimum radius, and at the same time, the intermediate wheel 244 moves along the side of the second friction table 242 from the minimum radius of the second friction table 242 to the maximum radius), that is, driving the speed regulating part 24 to switch from the high-speed gear to the low-speed gear, thereby driving the speed of the magnetic core 1 to decrease, that is, the more layers of copper wire wrapped around the surface of the magnetic core 1, the lower the rotation speed of the magnetic core 1 driven by the driving part 21.
[0035] Specifically, the staff or automatic equipment horizontally places the annular magnetic core 1 to be wound on the carrying mechanism 2, and the winding mechanism 3 drives the copper wire to be wound around the surface of the annular magnetic core 1 along the axial direction of the annular magnetic core 1. At this time, the intermediate wheel 244 in the speed regulating part 24 is in contact with the maximum radius of the first friction table 241 and the minimum radius of the second friction table 242 respectively. At this time, the vertical rod 211 connected to the second friction table 242 is in the maximum speed state. Under the action of the driving part 21, the driving part 21 drives the annular magnetic core 1 to rotate. The core 1 rotates with its own axis as the center of the circle, that is, it rotates on its own, and cooperates with the winding mechanism 3 to drive the copper wire to be wound along the axis direction of the annular core 1, so that the copper wire passes through the inner circle surface of the annular core 1 and is wound on the annular core 1 in a winding manner, completing the copper wire winding process on the surface of the annular core 1. As the number of copper wire layers on the surface of the annular core 1 increases, the length of the copper wire wound around the annular core 1 increases. Therefore, when the rotation speed of the annular core 1 remains unchanged, the copper wire cannot be wound around the annular core 1 in the same time, that is, the winding mechanism 3 needs to wind one circle of copper wire. The time becomes longer; and then when the thickness of the copper wire on the surface of the annular magnetic core 1 increases, the copper wire on the surface of the annular magnetic core 1 squeezes the diameter reducing portion 22, driving the end of the rotating rod 233 connected to the diameter reducing portion 22 to rotate upward, and the rotating rod 233 deflects with the axis of the second rotating shaft 232 as the center of the circle, and the other end of the rotating rod 233 drives the speed regulating lever 243 of the speed regulating portion 24 to move obliquely downward, changing the contact position of the intermediate wheel 244 with the first friction table 241 and the second friction table 242 (the intermediate wheel 244 moves along the side of the first friction table 241). The middle wheel 244 moves along the side edge of the second friction table 242 from the minimum radius of the second friction table 242 to the maximum radius), that is, the speed regulating part 24 is driven to switch from the high-speed gear to the low-speed gear. When the speed regulating part 24 is in the low-speed gear, the driving part 21 drives the speed of the annular magnetic core 1 to decrease to cooperate with the lengthened winding time of the winding mechanism 3, so as to avoid the magnetic core 1 moving too fast, resulting in the loose arrangement of the copper wire on the outer circle of the magnetic core 1.
[0036] It should be noted that, in this embodiment, the driving unit 21 drives the magnetic core 1 to rotate with its own axis as the center, and the winding mechanism 3 drives the copper wire to be wound on the surface of the annular magnetic core 1 along the axial direction of the annular magnetic core 1, that is, when the copper wire wound by the winding mechanism 3 is wrapped around the annular magnetic core 1 for one circle, the copper wire passes through the inner circular surface of the annular magnetic core 1.
[0037] Preferably, in this embodiment, the vertical rod 211 is vertically installed on the substrate, and a plurality of adjustment grooves are opened on the surface of the substrate, and the plurality of adjustment grooves are arranged circumferentially at intervals. One end of the vertical rod 211 is inserted into the adjustment groove, and a movable slider is rotatably installed on the end of the vertical rod 211 located inside the adjustment groove. The movable slider slides along the adjustment groove, and the movable slider is connected to the adjustment groove by an adaptive spring.
[0038] Specifically, the annular magnetic core 1 is placed on the driving part 21, and the placing blocks 212 on the plurality of vertical rods 211 clamp the outer wall of the annular magnetic core 1. When the annular magnetic core 1 is being wound, the driving motor starts to work, and the driving motor drives the vertical rods 211 connected thereto to rotate, and the placing blocks 212 rotate synchronously with the vertical rods 211. Under the action of friction, the annular magnetic core 1 is driven to rotate with its own axis as the center of the circle to meet the winding requirements of the winding mechanism 3. After the surface of the annular magnetic core 1 is wound with copper wire, the annular magnetic core 1 is The core 1 becomes thicker, and then when the annular core 1 contacts the placement block 212, the annular core 1 squeezes the placement block 212. Under the squeezing of the annular core 1, the moving slider carries the vertical rod 211 and the placement block 212 along the groove direction of the adjustment groove toward the center direction away from the annular core 1, thereby expanding the wrapped diameter length of multiple placement blocks 212 to adapt to the placement requirements of the thickened annular core 1. Moreover, under the action of the adaptive spring, the placement block 212 can fit the surface of the annular core 1 to meet the clamping and rotation requirements of the annular core 1.
[0039] In this embodiment, multiple vertical rods 211 are arranged at intervals along the circumference of the magnetic core 1, and the placement block 212 includes a wheel body fixedly connected to the vertical rods 211, and an annular groove is opened on the side wall of the wheel body. The side wall of the magnetic core 1 is inserted into the wheel groove. When it is necessary to drive the magnetic core 1 to rotate, the driving motor drives one of the vertical rods 211 to rotate. When any vertical rod 211 rotates under the drive of the driving motor, the placement block 212 on the vertical rod 211 rotates synchronously. Under the action of friction, the placement block 212 drives the magnetic core 1 to rotate with its own axis as the center of the circle, and cooperates with the winding mechanism 3 to complete the surface winding processing of the magnetic core 1.
[0040] It should be noted that the driving part 21 also includes a base plate, which is placed horizontally on the ground, and multiple vertical rods 211 are installed on the base plate. Furthermore, multiple slide grooves are opened on the base plate, and the multiple slide grooves correspond to the multiple vertical rods 211. The multiple vertical rods 211 are respectively installed in the multiple slide grooves, and the vertical rods 211 slide along the groove direction of the slide groove, and the slide groove and the vertical rods 211 are connected by traction springs. When it is necessary to install annular cores 1 of different sizes, the operator drives the vertical rod 211 to slide along the groove line of the slide groove to expand the gap between the multiple vertical rods 211 to meet the installation requirements of large-sized annular cores 1.
[0041] Preferably, in this embodiment, the surface of the wheel body is made of rubber. When the number of layers of copper wire wrapped around the surface of the magnetic core 1 increases, as the copper wire contacts the surface of the wheel body, the rubber on the surface of the wheel body deforms under the squeeze of the copper wire, protecting the copper wire from deformation and scratches when in contact with the wheel body, thereby ensuring the quality of the copper wire on the outer ring of the magnetic core 1.
[0042] The diameter-reducing portion 22 includes a diameter-reducing ring 221 , which is sleeved on the outside of the magnetic core 1 . The driving portion 21 drives the magnetic core 1 to rotate in a horizontal direction, and the magnetic core 1 passes through the inner circumferential surface of the diameter-reducing ring 221 horizontally.
[0043] The reducing portion 22 further includes a rod body, which connects the reducing ring 221 to the bottom plate. The rod body and the reducing ring 221 are detachably connected.
[0044] A connecting groove 25 is provided on the reducing ring 221, and the connecting groove 25 includes a sliding section 251 and an adjusting section 252. A sliding rod 222 is slidably installed in the sliding section 251, and the sliding rod 222 slides in the vertical direction. One end of the sliding rod 222 close to the magnetic core 1 is detachably connected with an abutment block 223, and the abutment block 223 and the surface of the magnetic core 1 abut against each other. The other end of the sliding rod 222 is rotatably connected to the rotating rod 233 of the adjusting part 23.
[0045] The slide bar 222 is connected to the connection slot 25 via a connection spring 224 . The connection spring 224 is vertically arranged. Both sides of the abutment block 223 are arc-shaped.
[0046] Specifically, when the thickness of the copper wire on the surface of the annular core 1 increases, that is, when the number of layers of copper wire on the surface of the annular core 1 increases, the copper wire on the surface of the annular core 1 squeezes the abutment block 223 of the diameter-changing portion 22, driving the abutment block 223 of the diameter-changing portion 22 to move away from the magnetic core 1 in the vertical direction. When the abutment block 223 of the diameter-changing portion 22 moves away from the magnetic core 1, it drives the rotating rod 233 of the adjusting portion 23 to deflect with the axis of the second rotating shaft 232 as the center. The other end of the rotating rod 233 drives the speed regulating lever of the speed regulating portion 24 to be pulled away from the speed regulating portion 24, driving the speed regulating portion 24 to switch from the high-speed gear to the low-speed gear, thereby changing the gear of the speed regulating portion 24. When the speed regulating portion 24 is in the low-speed gear, the driving portion 21 drives the rotation speed of the annular core 1 to decrease, so as to cooperate with the lengthened winding time of the winding mechanism 3, thereby avoiding the magnetic core 1 from moving too fast, resulting in the copper wire of the outer circle of the magnetic core 1 being loosely arranged.
[0047] The second rotating shaft 232 is eccentrically disposed on the fixing plate 231 . The second rotating shaft 232 is located on a side of the fixing plate 231 close to the diameter-changing portion 22 .
[0048] It should be noted that by eccentrically setting the second rotating shaft 232, the small upward displacement of the end of the rotating rod 233 connected to the sliding rod 222 is converted into a large downward displacement of the end of the rotating rod 233 connected to the speed regulating part 24, thereby achieving the purpose of switching the gear of the speed regulating part 24 and avoiding the situation that the gear of the speed regulating part 24 cannot be changed due to the small vertical displacement of the sliding rod 222, thereby affecting the normal switching of the gear of the speed regulating part 24.
[0049] Among them, in the initial state, the bottom surface of the abutment block 223 abuts against the surface of the magnetic core 1. When the copper wire is gradually wound on the surface of the magnetic core 1, the magnetic core 1 is also rotated under the action of the driving part 21. The side of the magnetic core 1 with the copper wire gradually passes through the reducing ring 221. As the winding mechanism 3 performs winding processing on the magnetic core 1, if the copper wire wound on the surface of the magnetic core 1 is in an unqualified state, that is, the copper wire on the surface of the magnetic core 1 is stacked up and down, as the driving part 21 drives the magnetic core 1 to rotate automatically When the copper wire on the magnetic core 1 passes through the reducing ring 221, the bottom of the abutment block 223 pushes the copper wire located above the stack to move toward the side of the magnetic core 1 to be wound, that is, the abutment block 223 pushes the copper wire on the surface of the magnetic core 1 located above the stack to move toward the side of the surface of the magnetic core 1 where the copper wire has not been wound, so that the copper wires stacked up and down are staggered and transformed into a state of being arranged in sequence. Therefore, when the copper wire arrangement on the surface of the magnetic core 1 is wrong, the abutment block 223 plays a corrective role, thereby improving the winding quality of the copper wire on the surface of the magnetic core 1.
[0050] Moreover, when the number of copper wire layers wound on the surface of the magnetic core 1 increases, the total thickness of the copper wire added to the surface of the magnetic core 1 increases. At this time, when the magnetic core 1 passes the copper wire through the reducing ring 221, the abutment block 223 cannot push the copper wire to the other side. As the abutment block 223 contacts the copper wire, the abutment block 223 is squeezed by the copper wire, and the abutment block 223 moves upward in the vertical direction, driving the slide bar 222 to move vertically upward synchronously. At this time, the connecting spring 224 is compressed, and the connecting spring 224 accumulates elastic potential energy, which is convenient for subsequent reset and repeated use. The slide bar 222 moves upward. When the second rotating shaft 232 is rotated, the rotating rod 233 is driven to rotate. The rotating rod 233 deflects with the axis of the second rotating shaft 232 as the center. The other end of the rotating rod 233 drives the speed regulating part 24 to move, and changes the gear of the speed regulating part 24. The regulating part 23 adjusts the speed regulating part 24 to switch to the low-speed gear, and slows down the horizontal movement speed of the magnetic core 1 driven by the driving part 21, so that the winding speed of the copper wire on the surface of the magnetic core 1 matches the feeding speed of the magnetic core 1, avoiding the magnetic core 1 from moving too fast, resulting in the occurrence of loose arrangement of the copper wire on the outer circle of the magnetic core 1, thereby improving the winding quality of the copper wire on the surface of the magnetic core 1.
[0051] In each embodiment of the present invention, the rotation of the rotating rod 233 makes the trajectory of its two ends arc-shaped, but it is obvious that the sliding rod 222 and the speed regulating part 24 can only move in a straight line. There are multiple solutions to this problem. One is to make the rotating rod 233 into a retractable axis. The other is to arrange the connection position of the rotating rod 233, the sliding rod 222 and the speed regulating part 24 into a match between the axis and the bar hole. The axis can not only rotate in the bar hole but also move back and forth. Obviously, there are other structures in the prior art that can also be realized, which will not be repeated.
[0052] Preferably, a first rotating shaft 225 is installed on the side wall of the abutment block 223, and the first rotating shaft 225 is horizontally arranged. A deflection pressure plate 226 is rotatably installed on the first rotating shaft 225. The deflection pressure plate 226 is connected to the first rotating shaft 225 through a torsion spring 227, and the deflection pressure plate 226 is connected to the side wall of the sliding rod 222 through an abutment spring 228.
[0053] The surface of the deflection plate 226 close to the magnetic core 1 is in an inclined shape.
[0054] When the copper wire wound by the winding mechanism 3 on the surface of the magnetic core 1 is in a sparse state, the movements of the various parts when the copper wire stacking state occurs are different according to the thickness of the wound copper wire. Specifically, the magnetic core 1 rotates synchronously with the copper wire under the action of the driving part 21, and as the copper wire is wound thicker, the copper wire on the surface of the magnetic core 1 contacts the inclined surface of the deflection pressure plate 226 facing the magnetic core 1;
[0055] When the wound copper wire is a thin copper wire, as the magnetic core 1 moves, one side of the copper wire located above the stacking position contacts the copper wire located below the stacking position, and the other side contacts the inclined surface of the deflection pressure plate 226. At this time, the copper wire in the stacked state is stuck by the deflection pressure plate 226. Then, as the magnetic core 1 continues to move, the deflection pressure plate 226 pushes the stacked copper wire to one side to avoid the copper wire stacking phenomenon on the surface of the magnetic core 1, thereby ensuring the winding quality of the copper wire on the surface of the magnetic core 1.
[0056] When the wound copper wire is a thick copper wire, as the magnetic core 1 moves, the copper wire located above the stacking position squeezes the bottom surface of the deflection pressure plate 226, and the deflection pressure plate 226 is squeezed to deflect away from the magnetic core 1 with the axial direction of the first rotating shaft 225 as the center, driving the deflection pressure plate 226 to change to a vertically placed state. At this time, as the magnetic core 1 continues to move, the vertically placed deflection pressure plate 226 pushes the thick copper wire located above the stacking position to move to one side, avoiding the horizontally placed The deflection pressure plate 226 cannot push the thick copper wire, causing the thick copper wire to lift up the abutment block 223, causing the slide rod 222 to drive the rotating rod 233 to rotate, and the rotating rod 233 deflects with the axis of the second rotating shaft 232 as the center. The other end of the rotating rod 233 drives the speed regulating part 24 to move, changing the gear position of the speed regulating part 24. The regulating part 23 adjusts the speed regulating part 24 to switch to the low-speed gear, slowing down the horizontal movement speed of the driving part 21 to drive the magnetic core 1, affecting the normal winding of the subsequent thick copper wire.
[0057] It should also be noted that when the copper wire wound by the winding mechanism 3 on the surface of the magnetic core 1 is in a dense state, the gap between the copper wires at the same horizontal height is smaller. When the copper wire wound on the surface of the magnetic core 1 is a thin copper wire, even if the copper wire is stacked up and down during winding, the stacked copper wire will not affect the winding quality of the magnetic core 1 because the copper wire is thin. When the wound copper wire is a thick copper wire, as the winding mechanism 3 winds the surface of the magnetic core 1, if the thick copper wire is stacked up and down, due to the long diameter of the thick copper wire, the gap between the copper wires below the stack is small, and the thick copper wire with a thicker diameter cannot be placed, which can easily cause the copper wire wound on the surface of the magnetic core 1 to become uneven, affecting the quality of the magnetic core 1.
[0058] Furthermore, in another embodiment of the present invention, when the copper wires on the surface of the magnetic core 1 are wound densely, in order to ensure that the thick copper wires stacked up and down are transformed into a state of being placed in sequence, a wire pushing mechanism 26 is also provided on the side wall of the abutment block 223. The wire pushing mechanism 26 is used to push the adjacent copper wires wound on the magnetic core 1 and located below the stack to one side, thereby expanding the gap between the adjacent copper wires and allowing the copper wires located above the stack to enter the gap.
[0059] The wire pushing mechanism 26 includes two sets of side plates 261, one end of the two sets of side plates 261 is movably connected to the abutment block 223, and can move away from or approach the abutment block 223, and the side plates 261 are connected to the abutment block 223 through a push spring 262 to achieve the approach reset after moving away. In this way, the two sets of side plates 261 are placed on the inner and outer opposite sides of the magnetic core 1, and the adjacent end surfaces of the two side plates 261 are provided with guide grooves 266, and the push blocks 263 are slidably installed in the guide grooves 266. A first wedge block 264 is installed on the side plate 261, and a second wedge block 265 is installed on both sides of the first rotating shaft 225. The first wedge block 264 and the second wedge block 265 directly abut against each other to form a wedge-shaped fit. An electrically controlled telescopic rod 267 is also installed on the side plate 261. The electrically controlled telescopic rod 267 controls the push block 263 to slide along the guide groove 266, pushing the copper wire located below the stack to one side, expanding the gap between adjacent copper wires, and allowing the copper wire located above the stack to enter the gap.
[0060] In this embodiment, the side of the push block 263 close to the magnetic core 1 is tapered, so that the push block 263 can be easily inserted into the gap between the copper wires.
[0061] Specifically, in the initial state, the thick copper wire does not stack up and down. At this time, the first wedge block 264 and the second wedge block 265 abut against each other so that the push spring 262 is in a stretched state, and the push block 263 and the copper wire are away from each other. When the thick copper wire stacks up and down, the copper wire located above the stack follows the movement of the magnetic core 1 and enters below the deflection pressure plate 226, squeezing the deflection pressure plate 226, driving the deflection pressure plate 226 to deflect, and the deflection pressure plate 226 drives the first rotating shaft 225 to deflect synchronously, and the second wedge block 265 on the first rotating shaft 225 rotates synchronously with the first rotating shaft 225, and the second wedge block 265 and the first wedge block 264 are gradually misaligned, and the first wedge block 264 loses the squeeze of the second wedge block 265. At this time, the push spring 262 shrinks and resets, driving the push block 263 to insert into the gap between the thick copper wires below the stack, and then the electrically controlled telescopic rod 267 extends, pushing the push block 263 to extend along the guide groove 266 in the direction away from the abutment block 223, thereby expanding the gap between adjacent copper wires below the stack, and then the thick copper wire above the stack enters into the expanded gap under the squeeze of the deflection pressure plate 226, thereby improving the winding quality of the thick copper wire during winding and improving the quality of the product.
[0062] Preferably, in this embodiment, the electrically-controlled telescopic rod 267 is in a passive trigger mode, wherein a control switch is provided on one side of the electrically-controlled telescopic rod 267, wherein when the first wedge block 264 and the second wedge block 265 squeeze each other, no component contacts the control switch, and the electrically-controlled telescopic rod 267 is in a retracted state; when the first wedge block 264 and the second wedge block 265 are misaligned and separated, the push spring 262 contracts, pulling the side plate 261 and the control switch to move in the direction of the second wedge block 265. At this time, the second wedge block 265 presses the control switch such as the travel switch, driving the electrically-controlled telescopic rod 267 to be energized, and the electrically-controlled telescopic rod 267 pushes the push block 263 to slide along the guide groove 266, thereby expanding the gap between adjacent copper wires located below the stack.
[0063] Preferably, when the wire pushing mechanism 26 is performing the wire pushing process, it pushes the copper wire located under the stack to the side away from the winding mechanism 3, ensuring that the winding mechanism 3 can perform the winding process normally without stopping and waiting, thereby improving the winding efficiency of the winding mechanism 3.
[0064] Specifically, the staff horizontally places the annular magnetic core 1 to be wound on the supporting mechanism 2, and the winding mechanism 3 densely winds the thick copper wire on the surface of the annular magnetic core 1. At this time, the intermediate wheel 244 in the speed regulating part 24 is in contact with the maximum radius of the first friction table 241 and the minimum radius of the second friction table 242 respectively. At this time, the vertical rod 211 connected to the second friction table 242 is in the maximum speed state. Under the action of the driving part 21, the driving part 21 drives the annular magnetic core 1 to rotate with its own axis as the center, that is, to rotate on its own, in cooperation with the winding mechanism 3. The copper wire is driven to be wound along the axial direction of the annular core 1, so that the copper wire passes through the inner surface of the annular core 1 and is wound on the annular core 1 in a winding manner, and the copper wire winding process on the surface of the annular core 1 is completed. When the thick copper wire is stacked up and down, the copper wire located above the stack follows the movement of the magnetic core 1 and enters below the deflection pressure plate 226, squeezes the deflection pressure plate 226, drives the deflection pressure plate 226 to deflect, and the deflection pressure plate 226 drives the first rotating shaft 225 to deflect synchronously, and the second wedge block 265 on the first rotating shaft 225 rotates synchronously with the first rotating shaft 225 When the first wedge block 264 is dislocated and separated from the second wedge block 265, the push spring 262 contracts and resets, driving the push block 263 to be inserted into the gap between the thick copper wires below the stack. At the same time, when the first wedge block 264 and the second wedge block 265 are dislocated and separated, the push spring 262 contracts, pulling the side plate 261 and the control switch to move in the direction of the second wedge block 265. At this time, the second wedge block 265 presses the control switch to drive the electric control telescopic rod 267 to be energized, and the electric control telescopic rod 267 pushes the push block 263. 63 extends along the groove direction of the guide groove 266 in the direction away from the winding mechanism 3, expanding the gap between the adjacent copper wires located below the stack, and then the thick copper wire located above the stack enters into the expanded gap under the extrusion of the deflection pressure plate 226, thereby improving the winding quality of the thick copper wire when winding. As the number of copper wire layers on the surface of the annular magnetic core 1 increases, the length of the copper wire wound around the annular magnetic core 1 increases. Therefore, when the rotation speed of the annular magnetic core 1 remains unchanged, the copper wire cannot be wound around the annular magnetic core 1 in the same time, that is, the time required for the winding mechanism 3 to wind a circle of the copper wire becomes longer;When the number of copper wire layers wound on the surface of the magnetic core 1 increases, the total thickness of the copper wire added to the surface of the magnetic core 1 increases. At this time, when the magnetic core 1 passes through the reducing ring 221 with the copper wire, the abutment block 223 cannot push the copper wire to the other side. As the abutment block 223 contacts the copper wire, the abutment block 223 is squeezed by the copper wire, and the abutment block 223 moves upward in the vertical direction, driving the slide bar 222 to move vertically upward synchronously. At this time, the connecting spring 224 is compressed, and the connecting spring 224 accumulates elastic potential energy to facilitate subsequent resetting for repeated use. When the slide bar 222 moves upward, it drives the rotating rod 233 to rotate. The rotating rod 233 deflects with the axis of the second rotating shaft 232 as the center, and the other end of the rotating rod 233 drives the speed regulating lever 243 of the speed regulating part 24 to move obliquely downward. The intermediate wheel 244 is moved to change the contact position between the intermediate wheel 244 and the first friction table 241 and the second friction table 242 (the intermediate wheel 244 moves along the side of the first friction table 241 from the maximum radius to the minimum radius of the first friction table 241, and the intermediate wheel 244 moves along the side of the second friction table 242 from the minimum radius to the maximum radius of the second friction table 242), that is, the speed regulating unit 24 is driven to switch from the high speed gear to the low speed gear, slowing down the horizontal movement speed of the driving unit 21 driving the magnetic core 1, so that the winding speed of the copper wire on the surface of the magnetic core 1 matches the feeding speed of the magnetic core 1, avoiding the excessive movement speed of the magnetic core 1, resulting in the loose arrangement of the copper wire on the outer ring of the magnetic core 1, thereby improving the winding quality of the copper wire on the surface of the magnetic core 1. ;
