Description

Technical Field

[0002] Small inductor components are commonly used electronic components in electronic products. During the manufacturing process, it is necessary to perform winding operations on the magnetic ring. For the annular magnetic ring, during the winding process, it is necessary to clamp it on the winding fixture, drive it to rotate through the winding fixture, and then synchronously pass the circular ring that drives the winding rotation through the annular magnetic ring, and then evenly wind the winding on the annular magnetic ring through the circular ring; when the size difference between the magnetic ring and the winding ring is too large, the magnetic ring will not pass through the rotation axis of the circular ring, and the position of the winding on the circular ring has the farthest distance and the closest distance between the magnetic ring, and the winding between the circular ring and the magnetic ring will appear loose and tight. This winding method will cause the tension of the winding when it is wound on the magnetic ring to be inconsistent, which is easy to cause the coils on the magnetic ring to be of different sizes, which not only wastes materials but also affects the appearance. At the same time, the loose coil will increase the volume of the magnetic ring, affecting the installation and use of the magnetic ring. Summary of the invention

[0031] like Figures 1 to 9 As shown, an induction coil winding device provided by an embodiment of the present invention includes a base 100, a mounting frame 101, a winding ring 102, a pay-off shaft 103, a magnetic ring 104, a clamping mechanism, a tensioning mechanism and a driving mechanism. The base 100 is fixedly arranged, the mounting frame 101 is fixedly installed on the base 100, the winding ring 102 is rotatably arranged on the mounting frame 101 around a first preset axis, the winding ring 102 is provided with a notch, a positioning plate 105 is provided at the notch, and the positioning plate 105 is threadedly connected to the winding ring 102. When the positioning plate 105 is removed from the winding ring 102, the winding ring 102 The two ends can move in opposite directions along the axial direction of the winding ring 102, the notch can become larger, the pay-off shaft 103 is rotatably set on the winding ring 102, there is friction between the pay-off shaft 103 and the winding ring 102, and the wire 127 is wound on the pay-off shaft 103; the magnetic ring 104 is rotatably set above the base 100 around the second preset axis, the magnetic ring 104 can enter the winding ring 102 through the notch, and the clamping mechanism is set on the base 100, which is used to clamp the magnetic ring 104 and drive the magnetic ring 104 to rotate around the second preset axis, and the first preset axis and the second preset axis are provided with an angle in the same plane.

[0032] The tensioning mechanism includes a fixed plate 106, a tensioning portion and a locking portion. The fixed plate 106 is fixedly installed on the inner side of the winding ring 102. The tensioning portion includes two rotating wheels 107. The two rotating wheels 107 can move closer to or farther away from each other on the fixed plate 106; the locking portion includes two fixed wheels 111. The two fixed wheels 111 can move closer to or farther away from each other on the fixed plate 106. The two rotating wheels 107 and the two fixed wheels 111 are distributed in a rectangular shape, and the two rotating wheels 107 are located in the same column, and the two fixed wheels 111 are located in the same column. The rotation axes of the two rotating wheels 107 and the two fixed wheels 111 are parallel to the first preset axis. When the distance between the tensioning mechanism and the magnetic ring 104 is from far to near, the two rotating wheels 107 move away from each other. The two fixed wheels 111 are close to each other, and the two fixed wheels 111 close to each other can clamp the wire 127 between them; when the distance between the tensioning mechanism and the magnetic ring 104 increases from near to far, the two rotating wheels 107 are close to each other and the two fixed wheels 111 are far away from each other; the wire 127 on the pay-off shaft 103 first passes between the two fixed wheels 111, then passes around the two rotating wheels 107 and is wound around the magnetic ring 104, and a wire groove is provided on the circumference of each rotating wheel 107 and the fixed wheel 111, and the wire 127 slides in the wire groove, which is convenient for guiding the wire 127 and preventing the wire 127 from slipping off the corresponding rotating wheel 107 or the fixed wheel 111; the driving mechanism is used to drive the winding ring 102 to rotate.

[0033] By the coordinated setting between the pay-off shaft 103 and the winding ring 102, when the tension on the wire 127 between the magnetic ring 104 and the pay-off shaft 103 is less than the friction force between the pay-off shaft 103 and the winding ring 102, the pay-off shaft 103 will not rotate relative to the winding ring 102, and the wire 127 between the magnetic ring 104 and the pay-off shaft 103 will not be in a relaxed state; when the tensioning mechanism on the winding ring 102 moves from the nearest point to the farthest point from the magnetic ring 104, the distance between the rotating wheel 107 and the magnetic ring 104 increases, and the wire 127 between the rotating wheel 107 and the magnetic ring 104 increases its own length in a taut state, at which time the two rotating wheels 107 gradually approach each other to the limit position, and the two fixed wheels 111 will move away from each other and will not restrict the movement of the wire 127; when the tensioning mechanism on the winding ring 102 moves from the farthest point to the nearest point from the magnetic ring 104, the rotating wheel 107 and the magnetic ring 10 4 is reduced, and the two rotating wheels 107 will move away from each other to increase the length of the wire 127 between the two wheels. Since there is friction between the pay-off shaft 103 and the winding ring 102, the wire 127 between the rotating wheel 107 and the magnetic ring 104 is easier to be added between the two rotating wheels 107. At the same time, the two fixed wheels 111 will approach each other to clamp and fix the wire 127 between the rotating wheel 107 and the pay-off shaft 103, and the wire 127 on the pay-off shaft 103 will no longer be pulled into the tensioning mechanism. The shortened length of the wire 127 between the rotating wheel 107 and the magnetic ring 104 is consistent with the increased length of the wire 127 in the tensioning mechanism, and the wire 127 between the fixed wheel 111 and the magnetic ring 104 is in a taut state, so that the tensioning force of the wire 127 when it is wound on the magnetic ring 104 is basically consistent, the coil covers the magnetic ring 104 more tightly and the coil size is more uniform.

[0034] In this embodiment, the tensioning mechanism further includes a positioning wheel 128, which is rotatably disposed on the fixed plate 106, and the positioning wheel 128 is located between the tensioning portion and the locking portion, and the rotation axis of the positioning wheel 128 is parallel to the first preset axis. A friction force is provided between the positioning wheel 128 and the fixed plate 106, and the wire 127 passes through the fixed wheel 111, first bypasses the positioning wheel 128 and then bypasses one of the rotating wheels 107, and the positioning wheel 128 is located between the rotating wheel 107 and the fixed wheel 111 (such as Figure 5As shown in the figure, a wire groove is also provided on the positioning wheel 128. The wire 127 passing between the two fixed wheels 111 is wound around in the wire groove on the positioning wheel 128 for one circle and then approaches one of the rotating wheels 107. In this way, there is enough friction between the wire 127 and the positioning wheel 128 to overcome the friction between the positioning wheel 128 and the fixed plate 106. At the same time, through the friction between the positioning wheel 128 and the fixed plate 106, when the two fixed wheels 111 approach each other and the wire 127 has not been fixed, the two rotating wheels 107 will preferentially pull the wire 127 between the magnetic ring 104 and the tensioning mechanism, further increasing the resistance to the pulling of the wire 127 on the pay-off shaft 103. When the wire 127 is wound around the magnetic ring 104, the wire 127 wrapped on the positioning wheel 128 can drive the positioning wheel 128 to rotate; when the two fixed wheels 111 are not in contact with the wire 127, the wire 127 between the positioning wheel 128 and the pay-off shaft 103 is located in the middle of the two fixed wheels 111, so that the two fixed wheels 111 will not affect the wire 127 between the positioning wheel 128 and the pay-off shaft 103 before the wire 127 is fixed.

[0035] In this embodiment, the tensioning part also includes a first plate 108 and a first telescopic rod 109. The first plates 108 are provided with two, one end of the two first plates 108 is respectively rotatably set on the fixed plate 106, and the other ends of the two first plates 108 are respectively fixedly installed with fixed shafts 110. The rotation axes of the two first plates 108 and the axes of the two fixed shafts 110 are parallel to the first preset axis. The two rotating wheels 107 are respectively sleeved on the two fixed shafts 110, and each rotating wheel 107 is rotatably connected to the corresponding fixed shaft 110. The two first plates 108 are respectively located on both sides of the positioning wheel 128, and the two first plates 108 are symmetrically arranged about the positioning wheel 128. The two ends of the first telescopic rod 109 are respectively sleeved on the two fixed shafts 110, and the first telescopic rod 109 is connected to the two fixed shafts 110. The shaft 110 is rotatably connected, and a first spring 129 is provided inside the first telescopic rod 109. When the first telescopic rod 109 is compressed, the first spring 129 starts to store energy, and the wire 127 passes around the positioning wheel 128 and then passes around the two rotating wheels 107 respectively. When the tensioning mechanism moves in the direction away from the magnetic ring 104, the magnetic ring 104 exerts a large pulling force on the wire 127, and the two first plates 108 rotate in opposite directions to compress the first telescopic rod 109. As the two first plates 108 rotate, the two rotating wheels 107 approach each other, and the distance between the two rotating wheels 107 is shortened. The wire 127 between the two rotating wheels 107 moves between the tensioning mechanism and the magnetic ring 104. At the same time, the two fixed wheels 111 are no longer in contact with the wire 127, and the wire 127 wound on the pay-off shaft 103 can continue to be pulled out.

[0036] In this embodiment, the locking portion also includes a second plate 112 and a second telescopic rod 113. Two second plates 112 are provided. One end of the two second plates 112 is rotatably set on the fixed plate 106 respectively. Two fixed wheels 111 are fixedly set on the other ends of the two second plates 112 respectively. Each first plate 108 is correspondingly arranged with one of the second plates 112. The rotation axis of the correspondingly arranged second plate 112 coincides with the rotation axis of the first plate 108. The positioning wheel 128 is located between the rotating wheel 107 and the fixed wheel 111. Two second telescopic rods 113 are provided. Each second telescopic rod 113 is installed on a group of coaxial first plates 108 and second plates 112. The second telescopic rod 113 is used to provide the coaxial second plates 112 with a force for rotating in the same direction when the first plate 108 rotates. When the ends with the rotating wheels 107 are close to each other and the second telescopic rod 113 is not retracted, the first plate 108 can pull the second plate 112 to rotate in the same direction as the first plate 108 through the second telescopic rod 113, and the two second plates 112 move away from each other, and the two fixed wheels 111 will not limit the wire 127 between them; when the ends of the two first plates 108 with the rotating wheels 107 are away from each other, the first plate 108 will push the corresponding second plate 112 to rotate around its own axis through a second telescopic rod 113, and the two second plates 112 move close to each other, and the two fixed wheels 111 will limit the wire 127 between them. At the same time, as the distance between the two rotating wheels 107 increases, the second telescopic rod 113 contracts, and the abutment force between the two fixed wheels 111 that abut against each other increases, and the limiting of the wire 127 is more secure.

[0037] In this embodiment, each second telescopic rod 113 includes a first sleeve and a second sleeve. The first sleeve is fixedly mounted on the first plate 108, and the second sleeve is fixedly mounted on the second plate 112. The first sleeve is sleeved on the second sleeve, and the first sleeve and the second sleeve are both arc-shaped. The arc centers of the first sleeve and the second sleeve are on the rotation axis of the first plate 108. A second spring is provided inside the second sleeve, and the two ends of the second spring are respectively connected to the first sleeve and the second sleeve. Each second telescopic rod 113 is located on a surface of the first plate 108 away from the positioning wheel 128 to avoid contact with the wire 127 on the positioning wheel 128. When the second spring is not compressed, the angle between the first plate 108 and the second plate 112 is 180°.

[0038] In another embodiment, the second telescopic rod 113 can be replaced by a torsion spring, which is sleeved on the rotating shaft of the coaxial first plate 108 and the second plate 112, and the two ends of the torsion spring are respectively connected to the first plate 108 and the second plate 112. When the first plate 108 rotates, the second plate 112 can be driven to rotate through the torsion spring. When the second plate 112 encounters resistance and stops rotating, the first plate 108 that continues to rotate will drive the torsion spring to rotate. The torsion spring after rotation is in a state of storing force, which increases the thrust of the second plate 112 to overcome the resistance and continue to rotate.

[0039] In this embodiment, the tensioning mechanism also includes two first magnets 114, two second magnets 115 and two third magnets 116. The two first magnets 114 are both arranged on the fixed plate 106, and the two first magnets 114 are located on both sides of the first telescopic rod 109 in the axial direction. The two second magnets 115 are respectively installed at both ends of the first telescopic rod 109. When the two first plates 108 in the tensioning part move away from each other, the two second magnets 115 approach the two first magnets 114 respectively. When the two rotating wheels 107 move away from each other under the action of the first spring 129 in the first telescopic rod 109, as the moving distance increases, the elastic potential energy of the first spring 129 decreases. Under the action of the first magnet 114 and the second magnet 115, the tendency of the two rotating wheels 107 to continue to move away from each other will be appropriately increased, which is used to solve the problem of reduced elastic potential energy of the first spring 129. The two third magnets 116 are respectively arranged on the sides of the two fixed wheels 111 that are close to each other, and the two third magnets 116 attract each other. When the two fixed wheels 111 approach each other to clamp the wire 127 therebetween, the third magnets 116 between the two fixed wheels 111 attract each other to provide a clamping force for the two fixed wheels 111.

[0040] In this embodiment, a side plate 117 is provided on the fixed plate 106. The side plate 117 is located at the end of the fixed shaft 110 away from the fixed plate 106. The side plate 117 is connected to the fixed plate 106 by bolts. When the wire 127 on the pay-off shaft 103 needs to pass through the tensioning mechanism, the side plate 117 can be removed to facilitate threading.

[0041] In this embodiment, a plurality of protrusions 118 are provided on the circumferential surface of each fixed wheel 111, which are used to increase the clamping force of the fixed wheel 111 on the wire 127. The protrusions 118 are arranged in the wire grooves of the fixed wheel 111. When the two fixed wheels 111 clamp the wire 127, the protrusions 118 on each fixed wheel 111 first contact the wire 127. Since the contact area between the protrusions 118 and the wire 127 is small, the pressure of the protrusions 118 on the wire 127 is relatively increased, thereby further reducing the probability of the wire 127 sliding between the two fixed wheels 111.

[0042] In this embodiment, the driving mechanism includes a guide wheel 119, a first motor 120 and a transmission belt 121. There are multiple guide wheels 119, and the multiple guide wheels 119 are rotatably set on the mounting frame 101, and the rotation axes of the multiple guide wheels 119 are parallel to the first preset axis. The multiple guide wheels 119 are set on the outer circumference of the winding ring 102, and the multiple guide wheels 119 are rollingly connected to the winding ring 102. The first motor 120 is fixedly installed on the base 100, and the transmission belt 121 is set on the output shaft of the first motor 120 and the guide wheel 119. After the first motor 120 rotates, it can drive the guide wheel 119 to rotate through the transmission belt 121. The guide wheel 119 can drive the winding ring 102 to rotate, and the winding ring 102 performs a winding action on the magnetic ring 104. A rotating plate 122 is provided on the mounting frame 101, and the rotating axis of the rotating plate 122 is parallel to the first preset axis. One of the guide wheels 119 is rotatably provided on the rotating plate 122. After the rotating plate 122 rotates around its own axis, the guide wheel 119 on the rotating plate 122 no longer contacts the winding ring 102, and the winding ring 102 can be removed from the mounting frame 101.

[0043] In this embodiment, the clamping mechanism includes a guide rail 123, a second motor 124 and a plurality of support rods 125. The guide rail 123 is arranged on the base 100, and the plurality of support rods 125 are slidably arranged on the guide rail 123. The second motor 124 is slidably arranged on the guide rail 123. A transmission wheel 126 is rotatably arranged on the output shaft of the second motor 124 and the plurality of support rods 125. The axis of the transmission wheel 126 is parallel to the axis of the magnetic ring 104, and the plurality of transmission wheels 126 have the same height relative to the base 100. The plurality of transmission wheels 126 are slidably connected to the outer peripheral surface of the magnetic ring 104. The adjustment of the distance between the plurality of support rods 125 enables the transmission wheel 126 to clamp magnetic rings 104 of different sizes, and at the same time adjusts the position of the magnetic ring 104 on the base 100 so that the tensioning mechanism will not produce motion interference with the magnetic ring 104.

[0044] The working principle and working method of an induction coil winding device provided in this embodiment are as follows:

[0045] First, install the pay-off shaft 103 with the wire 127 wound on the winding ring 102, then remove the positioning plate 105 on the winding ring 102, break the notch so that the magnetic ring 104 can pass through the notch, and the magnetic ring 104 and the winding ring 102 are interlocked, then reinstall the positioning plate 105, and then rotate the rotating plate 122 so that the winding ring 102 can be installed on the mounting frame 101 and contact with other guide wheels 119, and then rotate the rotating plate in the opposite direction. 122, so that the guide wheel 119 on the rotating plate 122 contacts with the winding ring 102. At this time, the winding ring 102 is fixed to the mounting frame 101, and the winding ring 102 can rotate on the mounting frame 101; then the second motor 124 and the plurality of support rods 125 on the moving base 100 are made to make the transmission wheel 126 on the second motor 124 and the transmission wheel 126 on the support rods 125 contact with the outer peripheral surface of the magnetic ring 104, so as to clamp the magnetic ring 104.

[0046] Then remove the side panel 117, pull the wire 127 on the winding ring 102, make the wire 127 pass between the two fixed wheels 111, then wrap around the positioning wheel 128, and extend toward one of the rotating wheels 107. After the wire 127 passes through the circumference of the rotating wheel 107, it extends toward the other rotating wheel 107. After the wire 127 passes through the positioning wheel 128, one rotating wheel 107 and the other rotating wheel 107 in turn, the wire 127 extends to the position of the magnetic ring 104 and is wound around the magnetic ring 104.

[0047] Then start the first motor 120 and the second motor 124, the first motor 120 drives the transmission belt 121 to transmit, the transmission belt 121 drives the guide wheel 119 to rotate, the rotating guide wheel 119 drives the winding ring 102 to rotate, the winding ring 102 drives the pay-off shaft 103 and the fixed plate 106 to rotate synchronously, as the fixed plate 106 rotates, the distance between the fixed plate 106 and the magnetic ring 104 changes, and the wire 127 is wound around the magnetic ring 104, and at the same time the second motor 124 drives the transmission wheel 126 on its output shaft to rotate, the rotating transmission wheel 126 drives the magnetic ring 104 to rotate, when the wire 127 is wound around the magnetic ring 104, the magnetic ring 104 rotates, and the wire 127 can be evenly wound around the magnetic ring 104.

[0048] As the winding ring 102 rotates, the distance between the fixed plate 106 and the magnetic ring 104 changes from far to near or from near to far; when the distance between the fixed plate 106 and the magnetic ring 104 is farthest, the two fixed wheels 111 do not clamp the wire 127 therebetween, and the first spring 129 is in a compressed state. When the distance between the fixed plate 106 and the magnetic ring 104 changes from far to near, the length of the wire 127 between the fixed plate 106 and the magnetic ring 104 is shortened, and the two first plates 108 rotate in opposite directions under the elastic force of the first spring 129, and drive the two rotating wheels 107 away from each other, then the length of the wire 127 between the two rotating wheels 107 increases, and the wire 127 between the positioning wheel 128 and the magnetic ring 104 is still in tension due to the elastic force of the first spring 129. State; while the two first plates 108 rotate in the opposite direction, the two first plates 108 push the two second plates 112 to rotate in the opposite direction through the corresponding second telescopic rods 113, and at the same time, the two fixed wheels 111 on the two second plates 112 approach each other, and the two fixed wheels 111 gradually approaching each other clamp the wire 127 between them, so as to prevent the two rotating wheels 107 moving away from each other from pulling the wire 127 from the pay-off shaft 103; as the distance between the two rotating wheels 107 increases, the elastic potential energy of the first spring 129 decreases, and at the same time, the second magnet 115 on the first telescopic rod 109 approaches the first magnet 114 on the fixed plate 106, and the suction force between the second magnet 115 and the first magnet 114 increases, driving the two rotating wheels 107 to continue to move away from each other. After the two fixed wheels 111 clamp the wire 127, the two second plates 112 no longer rotate, and the first plate 108 that continues to rotate will compress the second spring, and the second spring will push the second plate 112 to have a tendency to continue to rotate, and the clamping force between the two fixed wheels 111 will increase.

[0049] When the distance between the fixed plate 106 and the magnetic ring 104 increases from near to far, the length of the wire 127 between the fixed plate 106 and the magnetic ring 104 increases, and the two rotating wheels 107 are pulled closer to each other by the wire 127 between the fixed plate 106 and the magnetic ring 104, and the length of the wire 127 between the two rotating wheels 107 is shortened. At the same time, the two first plates 108 rotate, and the angle between the first plate 108 and the corresponding second plate 112 increases, and the second telescopic rod 113 gradually recovers. When the angle between the first plate 108 and the second plate 112 is 180°, the rotation of the first plate 108 drives the second plate 112 to rotate. At this time, the fixed wheels 111 on the two second plates 112 will move away from each other, no longer clamping the wire 127, and the wire 127 on the pay-off shaft 103 can be pulled out. In this process, the wire 127 between the fixed plate 106 and the magnetic ring 104 is always in a tensioned state with basically the same tension, and is wound more tightly and evenly on the magnetic ring 104.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
