Description

Technical Field

[0001] This utility model relates to the technical field of jigs and fixtures, specifically to a coil winding tool. Background Technology

[0002] Disposable prostate steam therapy devices use radiofrequency energy (such as heating coils) to heat water outside the body into steam. The steam is injected into the tissue through the opening of the puncture needle and rapidly diffuses through the gaps between tissue cells. Upon contact with the tissue, the steam immediately begins to cool and condense, releasing the stored heat energy, causing slight denaturation of the cell membranes, leading to instantaneous cell death and thus treating proliferating cells. Traditional disposable prostate steam therapy devices have complex manufacturing methods for the heating coils, and the consistency of coil length and tightness is poor, making them unsuitable for mass production. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide a coil winding fixture, which aims to solve the problem that the traditional method of manufacturing heating coils is relatively cumbersome, and the coil length and tightness between coils are inconsistent, which cannot meet the needs of mass production.

[0011] The outer diameter of the drive shaft is larger than the outer diameter of the insulating sleeve, and the end face of the drive shaft facing the insulating sleeve forms a winding limiting end face.

[0012] Optionally, the bracket includes a first support plate and a second support plate. The first support plate and the winding bar are spaced apart along the longitudinal direction of the base. The second support plate extends from the first support plate toward the winding bar. The wire limiting plate is disposed at one end of the second support plate near the winding bar. The outlet portion is disposed on the first support plate and near the wire limiting plate.

[0013] The wire limiting assembly also includes a wire limiting driver, which is connected to the first support plate and is used to drive the first support plate to move laterally along the base.

[0014] Optionally, the limit driver includes:

[0015] A second driver is provided on the base;

[0016] An adjusting screw is connected to the second driver and extends laterally along the base;

[0017] An adjusting nut is screwed to the adjusting screw and is disposed on the first support plate;

[0018] The second driver drives the adjusting screw to rotate, causing the adjusting nut to move along the adjusting screw, which in turn moves the first support plate and the second support plate together.

[0019] Optionally, the winding wheel assembly includes a winding wheel and at least one tensioning wheel, with at least one tensioning wheel located between the outlet and the winding wheel, such that the wire harness located between the outlet and the winding wheel remains taut; at least one tensioning wheel is disposed on the first support plate.

[0020] Optionally, the first support plate includes a support base and a support rod disposed on one side of the support base. The support base is connected to the adjusting nut. One end of the support rod is connected to the support base, and the other end extends toward the winding bar. The outlet portion is disposed at the end of the support rod away from the support base.

[0021] Optionally, the support rod is provided with an elongated hole, and the support base is provided with a mounting hole that corresponds to and mates with the elongated hole;

[0025] Optionally, the locking element is configured as a resilient locking screw.

[0026] Optionally, one of the first support plate and the base is provided with a slider, and the other is provided with a slide rail that slides in cooperation with the slider, the slide rail being arranged to extend laterally along the base.

[0027] The technical solution provided by this utility model has the following beneficial effects:

[0028] The coil winding fixture provided by this utility model includes a base, a winding assembly, and a wire limiting assembly. The winding wheel assembly is adapted to place a whole coil of wire on it, allowing the winding end of the wire to extend from the guide portion. When the wire contactes the winding bar, the winding driver drives the winding bar to rotate, thereby allowing the wire to be wound around the outer circumference of the winding bar to form a coil of a specific shape. Furthermore, the support of the wire limiting assembly has a stroke that moves laterally along the base, allowing the winding wheel assembly and the wire limiting plate mounted on the support to move laterally along the base. This allows the wire to be wound along the outer circumference of the winding bar while simultaneously winding along the extension direction of the winding bar, resulting in a coil spirally arranged laterally along the base. Moreover, because the wire limiting plate holds the wire to the winding bar during the winding process, and the wire extending from the guide portion adheres to the wire limiting plate and is wound onto the winding bar, the position of the winding end of the wire is more reliable and stable. As the support moves uniformly, the wire limiting plate also moves uniformly, allowing the wire bundle to be evenly distributed on the outside of the winding bar during winding, thus ensuring consistent tightness between the coils. Furthermore, since the support's travel distance is constant, the wire limiting plate's movement is also consistent, resulting in consistent coil lengths. This better guarantees the consistency of coil length and tightness, leading to higher coil quality and greater production efficiency. Attached Figure Description

[0039] This utility model provides a coil winding fixture 100, which can be used to wind various metal or non-metal wire harnesses, especially for winding heating coils in disposable prostate hot steam therapy devices, so as to ensure the consistency of the length and tightness of the heating coil, so that the heating temperature distribution is more uniform during heating and the effect of the therapy device is improved.

[0040] Specifically, please refer to Figures 1 to 3 In this embodiment, the coil winding fixture 100 includes a base 1, a winding assembly 2, and a wire limiting assembly 3.

[0041] The winding assembly 2 includes a winding bar 21 and a winding driver 22 drivably connected to the winding bar 21. The winding bar 21 extends laterally along the base 1, and the winding driver 22 is mounted on the base 1 and drives the winding bar 21 to rotate around a rotation axis arranged laterally along the base 1. By driving the winding bar 21 to rotate through the winding driver 22, the consistency of the rotation speed of the winding bar 21 can be better ensured, resulting in a more uniform winding speed of the wire harness when winding it.

[0042] The wire limiting assembly 3 includes a bracket 31, a winding wheel assembly 32 and a wire limiting plate 323 disposed on the bracket 31. The bracket 31 has a lateral travel along the base 1. The winding wheel assembly 32 has an outlet portion 322. The outlet portion 322 is disposed toward the circumferential side of the winding bar 21, so that after the wire bundle passes through the outlet portion 322, it extends along the tangential direction of the outer circumferential surface of the winding bar 21. After the winding end of the wire bundle is fixed to the winding bar 21, when the winding bar 21 rotates, the wire bundle can be wound around the outside of the winding bar 21 in the circumferential direction.

[0043] The winding wheel assembly 32 is adapted to allow the wire harness to be wound on it, and the winding end of the wire harness can extend from the guide portion 322 to be wound onto the winding bar 21. The wire limiting plate 323 has a winding position and an unlocking position. When in the winding position, the wire limiting plate 323 is held on the winding bar 21, and the wire harness passing through the guide portion 322 is attached to the wire limiting plate 323 to be wound onto the winding bar 21. The wire limiting plate 323 can mark the initial winding position of the wire harness on the one hand, and on the other hand, it can keep the position of the wire harness from shifting during the winding process, ensuring that the gap between adjacent coils is consistent.

[0044] In this embodiment, the winding wheel assembly 32 is adapted to hold a whole roll of wire, and the winding end of the wire can pass through the guide portion 322 after winding and extend out from the guide portion 322. When the wire contacts the winding bar 21, the winding driver 22 drives the winding bar 21 to rotate, so that the wire can be wound around the outer periphery of the winding bar 21 to form a coil of a specific shape. Moreover, the bracket 31 of the wire limiting assembly 3 has a stroke that moves laterally along the base 1, so that the winding wheel assembly 32 and the wire limiting plate 323 disposed on the bracket 31 can move laterally along the base 1 together. This allows the wire to be wound along the outer periphery of the winding bar 21 while also being wound along the extension direction of the winding bar 21, so as to obtain a coil that is spirally arranged along the lateral side of the base 1.

[0045] Furthermore, because the wire limit plate 323 is attached to the winding rod 21 during the winding process, and the coil exiting from the guide portion 322 is attached to the wire limit plate 323 and wound onto the winding rod 21, the position of the winding end of the wire harness is more reliable and stable. When the support 31 moves uniformly, the wire limit plate 323 also moves uniformly, allowing the wire harness to be evenly distributed on the outside of the winding rod 21 during winding, thus ensuring consistent tightness between the coils. Moreover, since the travel distance of the support 31 is constant, the movement amount of the wire limit plate 323 is also consistent, resulting in consistent coil lengths. This better ensures the consistency of the coil length and tightness, leading to better coil quality and higher production efficiency.

[0046] The shape and size of the base 1 are not specifically limited. The base 1 can be a flat plate, a frame, or a box, etc. Preferably, it is combined with... Figure 1 and Figure 2 As shown, the base 1 is a roughly square-shaped box. When the coil winding fixture 100 is operating normally, the aforementioned horizontal direction is defined as the left-right direction of the base 1, and the vertical direction refers to the front-back direction of the base 1. Unless otherwise specified, all descriptions of orientation in this invention shall be taken as such.

[0047] Specifically, the winding assembly 2 is mainly used to drive the winding bar 21 to rotate at a constant speed, so that the wire bundle is evenly wound on the winding bar 21. In conjunction with... Figure 1 and Figure 2 As shown, the winding driver 22 includes a first driver 221 disposed on the base 1 and a drive shaft 222 connected to the first driver 221. The drive shaft 222 extends laterally along the base 1 to connect with the winding bar 21. The first driver 221 can be configured as a drive electric cylinder or a drive pneumatic cylinder. A mounting plate is disposed laterally on the base 1, extending laterally along the base 1. The first driver 221 is disposed on the mounting plate, and the winding bar 21 and the base 1 are spaced apart vertically to provide winding space. The first driver 221 is disposed at one end of the drive shaft 222. The bracket 31 is disposed corresponding to the extension area of ​​the winding bar 21, such that the travel distance of the guide portion 322 corresponds to the lateral length of the winding bar 21.

[0048] like Figure 1 As shown, the winding rod 21 includes a rod body 211 and an insulating sleeve 212 fitted over the outside of the rod body 211. The rod body 211 is detachably connected to the drive shaft 222. When the coil winding is completed, the rod body 211 can be detached from the drive shaft 222 to remove the wound coil. After the coil is removed, the rod body 211 can be reinstalled on the drive shaft 222 for winding the next coil. The shape of the rod body 211 can be reasonably set according to the shape of the coil to be wound. For example, the cross-section of the rod body 211 can be approximately circular, square, polygonal, or other irregular shapes to meet the manufacturing requirements of different heating coils. Moreover, a coil winding fixture 100 can be equipped with multiple winding rods 21, and the shapes or sizes of the multiple winding rods 21 can be set differently, so that it can be applied to the winding of more coils, making the coil winding fixture 100 more applicable.

[0049] Wherein, the outer diameter of the drive shaft 222 is larger than the outer diameter of the insulating sleeve 212, and the end face of the drive shaft 222 facing the insulating sleeve 212 forms a winding limiting end face. This limiting end face can form the starting end of coil winding to mark the starting position of winding, ensuring that the starting position of each coil is consistent, and further ensuring that the overall length of the coil is consistent.

[0050] Combination Figure 1 and Figure 3 As shown, the bracket 31 includes a first support plate 311 and a second support plate 312, which are detachably connected. The first support plate 311 and the winding bar 21 are spaced apart along the longitudinal direction of the base 1, providing sufficient installation space for the winding wheel assembly 32 and preventing interference with the winding bar 21 when the bracket 31 moves. The second support plate 312 extends from the first support plate 311 toward the winding bar 21, and the wire limiting plate 323 is located at the end of the second support plate 312 near the winding bar 21. The lead-out portion 322 is located on the first support plate 311 and near the wire limiting plate 323, allowing the wire bundle passing through the lead-out portion 322 to better conform to the wire limiting plate 323 for winding onto the winding bar 21.

[0051] Preferably, the wire limiting assembly 3 further includes a wire limiting driver 33, which is connected to the first support plate 311 and is used to drive the first support plate 311 to move laterally along the base 1. When the first support plate 311 moves, it can drive the second support plate 312 to move together, so that the winding wheel assembly 32 and the wire limiting plate 323 disposed on the first support plate 311 and the second support plate 312 can move together, so that the wire bundle can be evenly wound on the winding bar 21 laterally along the base 1.

[0052] The limit actuator 33 includes a second actuator 331, an adjusting screw 332, and an adjusting nut 333. The second actuator 331 is mounted on the base 1. Preferably, the second actuator 331 is mounted on the mounting plate and is spaced apart from the first actuator 221 along the transverse direction of the base 1. The second actuator 331 can be configured as a drive electric cylinder or a drive pneumatic cylinder.

[0053] The adjusting screw 332 is connected to the second driver 331 and extends laterally along the base 1. The adjusting nut 333 is screwed to the adjusting screw 332 and is mounted on the first support plate 311. The second driver 331 drives the adjusting screw 332 to rotate, causing the adjusting nut 333 to move along the adjusting screw 332, thereby moving the first support plate 311 and the second support plate 312 together. The screw and nut structure allows the first support plate 311 to move laterally along the base 1. Moreover, due to the high adjustment accuracy and low operating noise of the screw and nut structure, the gap between adjacent wire bundles can be adjusted more precisely during coil winding, thereby meeting the winding requirements of wire bundles of different thicknesses or different coil tightness.

[0054] In one embodiment, the winding wheel assembly 32 includes a winding wheel and at least one tensioning wheel 321. At least one tensioning wheel 321 is located between the output portion 322 and the winding wheel, ensuring that the wire harness located between the output portion 322 and the winding wheel remains taut, guaranteeing a consistent output length of the wire harness during winding, thereby ensuring winding uniformity. At least one tensioning wheel 321 is mounted on the first support plate 311, allowing the tensioning wheel 321 to move along with the first support plate 311, thereby ensuring a continuous and stable output of the wire harness.

[0055] The outlet 322 is configured as a wire tube, which is a cylindrical shape with open ends. The axis of the wire tube is perpendicular to the axis of the winding bar 21. After the wire harness is output from the tension wheel 321, it passes through one end of the wire tube and exits from the other end of the wire tube to be wound around the outside of the winding bar 21.

[0056] Furthermore, combined Figures 1 to 3 As shown, the first support plate 311 includes a support base 3111 and a support rod 3113 disposed on one side of the support base 3111. The support base 3111 is connected to the adjusting nut 333. One end of the support rod 3113 is connected to the support base 3111, and the other end extends toward the winding bar 21. The guide portion 322 is disposed at the end of the support rod 3113 away from the support base 3111, so that the guide portion 322 can be closer to the winding bar 21, thereby making the winding more stable.

[0057] Moreover, such as Figure 2As shown, the support rod 3113 has an elongated hole, and the support base 3111 has a mounting hole corresponding to the elongated hole. The wire limiting assembly 3 also includes a connector, which passes through the elongated hole and the mounting hole to connect and fix the support base 3111 and the support rod 3113. The connector can be a screw or a bolt. By connecting the connector to different positions of the elongated hole, the length of the support rod 3113 extending beyond the support base 3111 can be adjusted, thereby adjusting the distance between the guide portion 322 and the winding bar 21. When the outer diameter of the winding bar 21 or the outer diameter of the wire harness changes, the wire harness can better fit the corresponding winding bar 21, ensuring better winding performance.

[0058] The wire limiting plate 323 constrains the wire bundle during winding, ensuring uniform coil winding and preventing it from easily detaching from the winding bar 21. Furthermore, upon completion of winding, the wire limiting plate 323 moves away from the winding bar 21, making the wound coil easy to remove. It is understood that the wire limiting plate 323 can move in various ways. For example, the wire limiting plate 323 may have a linear reciprocating stroke along the transverse or longitudinal direction of the base 1, or it may have a stroke that moves along an arc track, etc.

[0059] Preferably, one end of the wire limiting plate 323 is rotatably connected to the second support plate 312, and the other end of the wire limiting plate 323 is provided with a hook portion 3231, and a notch is provided on one side of the hook portion 3231. When the wire limiting plate 323 is flipped in the forward direction, the hook portion 3231 of the wire limiting plate 323 can be engaged with the outside of the winding rod 21 from the notch, and the hook portion 3231 is spaced apart from the outer peripheral surface of the winding rod 21, so that when the first support plate 311 moves laterally along the base 1, the hook portion 3231 can move relative to the winding rod 21 to cooperate with the lead-out portion 322 for uniform winding. When the wire limiting plate 323 is flipped in the reverse direction, the hook portion 3231 can be disengaged from the winding rod 21 from the notch, making the finished coil easy to remove.

[0060] The wire limiting assembly 3 further includes a locking member 324. When in the winding position, the hook 3231 engages with the outside of the winding bar 21 and can move along the winding bar 21. The locking member 324 locks the wire limiting plate 323 onto the second support plate 312, thereby restricting the wire limiting plate 323 to the winding position and ensuring winding stability. When in the unlocked position, the locking member 324 unlocks the wire limiting plate 323, allowing the wire limiting plate 323 to rotate and separate from the winding bar 21, thus making it easy to remove the wound coil.

[0061] The locking element 324 is configured as an elastic locking screw, which makes the locking reliable and allows the adjusting limit plate 323 to be slightly adjusted in the lateral position along the base 1.

[0062] Moreover, combined Figure 1 and Figure 3 As shown, a slider 3112 is provided on one of the first support plate 311 and the base 1, and the other is provided with a slide rail 11 that slides and engages with the slider 3112. The slide rail 11 extends laterally along the base 1. Under the guiding sliding engagement of the slider 3112 and the slide rail 11, the first support plate 311 is more stable and less prone to shaking when moving along the base 1, which makes the wire harness passing through the outlet 322 more stable and improves the winding effect.

[0063] Of course, in one embodiment, the coil winding fixture 100 further includes a controller and a detection structure. The controller is disposed on the base 1 and is electrically connected to the detection structure, the first driver 221, and the second driver 331. The controller controls the operation of the first driver 221 and the second driver 331 based on the detection results of the detection structure. Specifically, the detection structure may include a first wire harness position detector and a second wire harness position detector. The first wire harness position detector can detect whether the wire harness passing through the outlet 322 is properly wound. When the wire harness is properly wound, the detection result is transmitted to the controller, thereby controlling the first driver 221 to operate for winding the wire harness. The second wire harness position detector can detect the relative position of the lead-out part 322 and the winding bar 21. When the lead-out part 322 is located at the winding start position of the winding bar 21, the controller can control the first driver 221 to start working while simultaneously controlling the second driver 331 to start working, so that the lead-out part 322 can move laterally along the base 1, thereby allowing the wire harness to be wound sequentially along the winding bar 21. The controller makes the operation of the entire coil winding fixture 100 more intelligent, and can more accurately control the length and tightness of the wound coil, thereby better improving the processing quality and efficiency of the winding process.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
