Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a transformer coil winding machine. Background Technology

[0002] A transformer coil winding machine is a specialized piece of equipment used to wind transformer coils. After the coil bobbin is clamped onto the winding machine, the machine rotates the bobbin, causing the wire to wind onto it. Currently, some transformer coils have large-diameter wires, which can cause the wire wound onto the bobbin to spring back, leading to a loose coil. To address this, existing winding machines are equipped with clamping components to tighten the wound wire, ensuring a closer fit to the bobbin. However, the clamping distance of these components needs to be manually adjusted to match the transformer coil size. Too small a clamping distance can scratch the wire, while too large a distance can cause the wire to loosen, making operation inconvenient. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a transformer coil winding machine.

[0004] A transformer coil winding machine according to an embodiment of the present invention includes a base, a translation component, a rotation component, and a clamping component. The translation component is disposed on the base, the rotation component has a rotatable main shaft, and the clamping component is disposed around the main shaft. The translation component connects to the rotation component or the clamping component. The translation component drives the rotation component or the clamping component to move the clamping component relative to the main shaft along the axial direction of the main shaft. The clamping component includes:

[0005] Mounting bracket, connected to the base, the mounting bracket being disposed on the periphery of the spindle;

[0006] Multiple radial sliders, each of which is slidably connected to the mounting base, each of which slides radially along the main shaft, all of which are arranged sequentially along the circumference of the main shaft, and each of which has a radial rolling element provided on the side wall facing the main shaft;

[0007] Multiple radial elastic elements are provided, with each radial slider disposed between itself and the mounting base. The elastic force of the radial elastic elements causes the radial slider to tend to move toward the main shaft.

[0008] The transformer coil winding machine according to the present invention has at least the following beneficial effects: the transformer coil bobbin is clamped onto the main shaft of the rotating assembly, the main shaft drives the bobbin to rotate around the axis to wind the wire onto the bobbin, and the wire rotates to the position of the clamping assembly; the mounting seat of the clamping assembly is set on the periphery of the bobbin, and the radial elastic element pushes the radial slider to move towards the side wall of the bobbin, so that the radial rolling elements abut against the wire wound on the bobbin. Since multiple radial rolling elements are arranged sequentially along the circumference of the main shaft, the multiple radial rolling elements abut against the wire of the bobbin in sequence, which helps to clamp and shape the wire that has just been wound onto the bobbin and prevents the wire from springing back. Later, loosening occurs; during the rotation of the frame, the translation component drives the rotation component or the clamping component to move, causing the clamping component to move axially relative to the frame along the main shaft, and causing the radial rolling element to move along the continuously wound wire to adapt to the position of the subsequent wound wire; the clamping component can automatically match the size of different transformer coils to ensure that the wire fits the frame, and the elastic force provided by the radial elastic element maintains the radial rolling element against the wire, so that the radial rolling element presses the wire and the frame with a relatively constant pressure, and the rotation of the radial rolling element relative to the wire can effectively reduce the damage to the wire and ensure that the wire fits the frame, making the operation of the winding machine more convenient.

[0009] According to some embodiments of the present invention, the clamping assembly further includes:

[0010] Multiple axial sliders are slidably connected to multiple radial sliders facing the sidewall of the main shaft. The axial sliders and the radial rolling elements are offset along the axial and radial directions of the main shaft. Each axial slider slides along the axial direction of the main shaft, and each axial slider has an axial rolling element on the side facing the radial rolling element.

[0011] Multiple axial elastic elements are provided, with the axial elastic elements disposed between the axial slider and the radial slider. The elastic force of the axial elastic elements causes the axial slider to tend to move toward the radial rolling element.

[0012] According to some embodiments of the present invention, the radial rolling element and the axial rolling element are offset circumferentially along the main shaft.

[0013] According to some embodiments of the present invention, the radial rolling elements and the axial rolling elements are arranged alternately along the rotation direction of the main shaft.

[0032] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0033] Reference Figures 1 to 6 As shown, this utility model provides a transformer coil winding machine.

[0034] The transformer coil winding machine includes a base 100, a translation component 200, a rotation component 300, a clamping component 400, and a wire feeding component 500.

[0035] Reference Figure 1 and Figure 2 As shown, the translation component 200 is disposed on the base 100, and the translation component 200 is connected to the rotation component 300. The translation component 200 drives the rotation component 300 to translate relative to the base 100.

[0036] In this embodiment, the translation component 200 adopts a lead screw and nut mechanism. The translation component 200 includes a motor, a lead screw, a nut, and a slider. The base 100 is provided with a slide groove. The motor is mounted on the base 100, and the lead screw is mounted in the slide groove. The output shaft of the motor is connected to the lead screw. The nut is sleeved on the outside of the lead screw and is connected to the slider. The slider is slidably mounted in the slide groove. The motor drives the lead screw to rotate, causing the nut and the slider to move along the slide groove. The slider is connected to the rotation component 300, so the slider drives the rotation component 300 to move along the slide groove.

[0037] In this embodiment, the rotating assembly 300 includes a rotary motor, a main shaft 310, and a tensioning shaft 320. The rotary motor is mounted on the slider of the translation assembly 200 and is connected to the main shaft 310. The rotary motor drives the main shaft 310 to rotate around its own axis. The tensioning shaft 320 is mounted on the outside of the main shaft 310 and rotates synchronously with the main shaft 310.

[0038] In this embodiment, the tensioning shaft 320 is a gas-expanding shaft, a specialized mechanical shaft that achieves rapid winding and unwinding through inflation. It is widely used in the material handling stages of printing, coating, slitting, and rewinding machinery. The gas-expanding shaft controls the extension and retraction of the key strips or protrusions on its surface by inflating and deflating the shaft, allowing for the fixing or releasing of the transformer frame 700 within seconds. To reduce damage to the frame 700 caused by the tensioning shaft 320, the key strips or protrusions on the shaft surface facing the sidewall of the frame 700 are designed as arc surfaces to increase the contact area between the key strips or protrusions and the frame 700, thereby reducing the pressure exerted on the frame 700 by the key strips or protrusions.

[0039] In some embodiments, the tensioning shaft 320 is a mechanical tensioning shaft. The principle of the mechanical tensioning shaft is roughly the same as that of the gas tensioning shaft. The difference is that the mechanical tensioning shaft is equipped with a push block that slides along the axis inside. When the push block moves forward, the outer wall of the push block pushes the key strip on the surface of the shaft to extend outward. When the push block moves in the opposite direction, the key strip on the surface of the shaft is squeezed by the external skeleton 700 and retracted into the shaft body.

[0040] Setting the tensioning shaft 320 helps to fix the skeleton 700 inside the skeleton 700, so that the outer peripheral surface of the skeleton 700 bears uniform pressure and reduces the deformation of the skeleton 700 during the winding of the wire 600.

[0041] In some embodiments, the rotating assembly 300 does not have a tensioning shaft 320, and the main shaft 310 is directly connected to the frame 700. A flange ring is provided on the periphery of the main shaft 310, and the end face of the frame 700 is connected to the flange ring with screws.

[0042] Reference Figure 4 and Figure 6As shown, the wire feeding assembly 500 and the base 100 are fixed in position relative to each other. The wire feeding assembly 500 is an industrial equipment that realizes precise release of wire through a mechanical transmission system. The wire feeding assembly 500 includes a rotatable wire feeding shaft and a tension control mechanism. The wire reel is installed on the wire feeding shaft of the wire feeding assembly 500. After the wire 600 of the wire reel is wound around the skeleton 700 of the main shaft 310 of the rotating assembly 300, the rotating assembly 300 drives the wire 600 to wind onto the skeleton 700. The wire 600 pulls the wire feeding shaft of the wire feeding assembly 500 to rotate. The tension control mechanism controls the rotation of the wire feeding shaft to keep the tension of the wire 600 winding onto the skeleton 700 within a preset range, ensuring that the wire 600 is tightly attached to the skeleton 700.

[0043] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the wire 600 unwound by the wire feeding assembly 500 is wound onto the bobbin 700. The main shaft 310 of the rotating assembly 300 drives the bobbin 700 to rotate, causing the wire 600 to drive the wire feeding shaft of the wire feeding assembly 500 to rotate. Since the relative position between the base 100 and the wire feeding assembly 500 is fixed, during the process of the main shaft 310 of the rotating assembly 300 driving the bobbin 700 to rotate around its own axis, the translation assembly 200 needs to drive the bobbin 700 to translate along its own axis, so that the translation rate of the bobbin 700 is related to the rotation rate of the bobbin 700. In this embodiment, the wire 600 is spirally wound into a coil along the axis of the bobbin 700. The time required for the bobbin 700 to drive the wire 600 to rotate one revolution can be calculated based on the rotation rate. The translation rate of the bobbin 700 can be calculated by dividing the coil pitch by the time, so that the wire 600 can translate with the bobbin 700 after being wound onto it, and the starting point of the wire 600 winding remains unchanged.

[0044] Reference Figures 1 to 6 As shown, there are three clamping assemblies 400, with the axis of the main shaft 310 as the relative left and right directions. The three clamping assemblies 400 are arranged in front of, below and behind the main shaft 310. The wire 600 unwound by the wire feeding assembly 500 is wound around the outside of the skeleton 700 above the main shaft 310, which avoids interference between the clamping assemblies 400 and the wire 600 unwound by the wire feeding assembly 500, and also helps to arrange the three clamping assemblies 400 reasonably.

[0045] Reference Figure 4 and Figure 6 As shown, each clamping assembly 400 includes a mounting base 410 and a drive mechanism 460. The drive mechanism 460 is connected to the base 100 and the mounting base 410. The mounting base 410 is located on the periphery of the spindle 310. The drive mechanism 460 drives the mounting base 410 to move closer to or away from the spindle 310.

[0046] In the clamping assembly 400 located in front of the main spindle 310, the drive mechanism 460 is a swing drive mechanism. The drive mechanism 460 includes a swing rod and a cylinder. The bottom end of the swing rod is hinged to the base 100, and the rotation axis of the swing rod is parallel to the axis of the main spindle 310. The top end of the swing rod is connected to the mounting seat 410. The bottom end of the cylinder is hinged to the base 100, and the top end of the cylinder is hinged to the swing rod. The swing rod drives the mounting seat 410 to move through the extension and retraction of the cylinder. The drive mechanism 460 drives the mounting seat 410 to swing back and forth. The drive mechanism 460 drives the mounting seat 410 to swing backward toward the main spindle 310. The drive mechanism 460 drives the mounting seat 410 to swing forward away from the main spindle 310.

[0047] In the clamping assembly 400 located behind the main spindle 310, the drive mechanism 460 is a swing drive mechanism. The drive mechanism 460 includes a swing rod and a cylinder. The bottom end of the swing rod is hinged to the base 100, and the rotation axis of the swing rod is parallel to the axis of the main spindle 310. The top end of the swing rod is connected to the mounting seat 410. The bottom end of the cylinder is hinged to the base 100, and the top end of the cylinder is hinged to the swing rod. The swing rod drives the mounting seat 410 to move through the extension and retraction of the cylinder. The drive mechanism 460 drives the mounting seat 410 to swing in the front and back direction. The drive mechanism 460 drives the mounting seat 410 to swing forward and closer to the main spindle 310. The drive mechanism 460 drives the mounting seat 410 to swing backward and away from the main spindle 310.

[0048] In the clamping assembly 400 located below the spindle 130, the drive mechanism 460 is a lifting drive mechanism. The drive mechanism 460 drives the mounting base 410 to move up and down in the vertical direction. The drive mechanism 460 drives the mounting base 410 to move upward and closer to the spindle 310. The drive mechanism 460 drives the mounting base 410 to move downward and away from the spindle 310.

[0049] The drive mechanism 460 moves the mounting base 410 away from the spindle 310, so as to pick up or put down the skeleton 700 or install the skeleton 700 from the end of the spindle 310, avoiding interference between the skeleton 700 and the clamping assembly 400. The drive mechanism 460 can also adjust the distance between the mounting base 410 and the spindle 310 so that the clamping assembly 400 can match skeletons 700 of different sizes and models.

[0050] In some embodiments, the drive mechanism 460 employs a linear drive mechanism to drive the mounting base 410 to move radially along the spindle 310.

[0051] Reference Figure 3 and Figure 5 As shown, each clamping assembly 400 also includes a plurality of radial sliders 420, a plurality of radial elastic elements 430, a plurality of axial sliders 440, and a plurality of axial elastic elements 450.

[0052] The mounting base 410 is arc-shaped, and each mounting base 410 has multiple mounting slots on its side wall facing the main shaft 310. The mounting slots are spaced apart circumferentially along the main shaft 310. Multiple radial sliders 420 are slidably disposed in the mounting slots, moving closer to or away from the main shaft 310. Each mounting slot has a radial elastic element 430 connected to the radial slider 420. The radial elastic element 430 is a compression spring, and its elastic force pushes the radial slider 420 to move towards the main shaft 310.

[0053] The arc-shaped mounting base 410 makes the sliding path of the multiple radial sliders 420 closer to the radial path of the main shaft 310, making the distance between the multiple radial sliders 420 and the skeleton 700 more uniform, ensuring that the elastic force of the multiple radial elastic elements 430 on the radial sliders 420 is approximately the same, and making the pressure of the multiple radial rolling elements 421 on the wire 600 wound around the skeleton 700 evenly distributed, which helps the wire 600 to fit more tightly against the skeleton 700.

[0054] Reference Figure 3 and Figure 5 As shown, each radial slider 420 has a receiving groove on its side wall facing the main shaft 310. A radial rolling element 421 is installed in the receiving groove. The radial rolling element 421 rotates in the receiving groove, and the rotation axis of the radial rolling element 421 is parallel to the rotation axis of the main shaft 310.

[0055] Reference Figure 3 As shown, each radial slider 420 has a sliding groove on its side wall facing the main shaft 310. The sliding groove is arranged along the axial direction of the main shaft 310. Each sliding groove is provided with an axial slider 440, which slides along the sliding groove. Each sliding groove is provided with an axial elastic element 450, which is a compression spring. The axial elastic element 450 is connected to the axial slider 440, and the elastic force of the axial elastic element 450 pushes the axial slider 440 to move axially.

[0056] In this embodiment, refer to Figure 3As shown, the radial rolling element 421 and the axial slider 440 are offset along the axial direction of the main shaft 310. The axial slider 440 has a receiving cavity on its side wall facing the radial rolling element 421. The axial rolling element 441 is disposed in the receiving cavity and rotates in the receiving cavity. The rotation axis of the axial rolling element 441 is perpendicular to the axis of the main shaft 310. Taking the position of the radial rolling element 421 relative to the axial slider 440 as the left direction, the elastic force of the axial elastic element 450 pushes the axial slider 440 to move to the left and approach the radial rolling element 421. When the radial rolling element 421 abuts against the wire 600 wound on the skeleton 700 along the radial direction of the main shaft 310, the axial rolling element 441 abuts against the wire 600 wound on the skeleton 700 along the axial direction of the main shaft 310, thereby achieving the radial and axial compression of the wound wire 600 from the skeleton 700.

[0057] Reference Figure 5 As shown, multiple radial sliders 420 are distributed circumferentially along the main shaft 310, and the radial rolling elements 421 and axial rolling elements 441 on each radial slider 420 are coarsely spread circumferentially along the main shaft 310, which can avoid the radial rolling elements 421 and axial rolling elements 441 interfering with each other, causing the axial rolling elements 441 to fail to press the wire 600.

[0058] In this embodiment, refer to Figure 5 As shown, the bobbin 700 rotates counterclockwise to wind the wire 600. Radial rolling elements 421 and axial rolling elements 441 are arranged alternately in a counterclockwise direction. This ensures that the radial rolling elements 421 first press the wire 600 radially against the bobbin 700, making the wire 600 tightly adhere to the bobbin 700. Then, the axial rolling elements 441 press the wire 600 axially against the bobbin 700, making the wire 600 tightly adhere to the already wound coil. This ensures that the wire 600 is tightly attached to the bobbin 700. This prevents the wire 600 from moving axially along the bobbin 700 before it is fully attached, thus avoiding misalignment between the wire 600 and the radial rolling elements 421.

[0059] The transformer coil bobbin 700 is clamped onto the spindle 310 of the rotating assembly 300. The spindle 310 drives the bobbin 700 to rotate around the axis, causing the wire 600 to wind onto the bobbin 700. The wire 600 rotates to the position of the clamping assembly 400. The mounting base 410 of the clamping assembly 400 is set on the periphery of the bobbin 700. The radial elastic element 430 pushes the radial slider 420 to move towards the side wall of the bobbin 700, so that the radial rolling element 421 presses the wire 600 wound on the bobbin 700. Multiple radial rolling elements 421 abut against the wire 600 of the bobbin 700 in sequence, which helps to clamp and shape the wire 600 that has just been wound onto the bobbin 700, and prevent the wire 600 from loosening after springing back.

[0060] During the rotation of the skeleton 700, the translation component 200 drives the rotation component 300 or the clamping component 400 to move, so that the clamping component 400 moves relative to the skeleton 700 along the axial direction of the main shaft 310, causing the radial rolling element 421 to move along the continuously wound wire 600 to adapt to the position of the subsequently wound wire 600.

[0061] The clamping assembly 400 can automatically match the size of different transformer coils to ensure that the wire 600 fits the frame 700. The elastic force provided by the radial elastic element 430 keeps the radial rolling element 420 abutting against the wire 600, so that the radial rolling element 421 clamps the wire 600 and the frame 700 with a relatively constant pressure. The radial rolling element 421 rotates relative to the wire 600, which can effectively reduce the damage to the wire 600 and ensure that the wire 600 fits the frame 700, making the operation of the winding machine more convenient.

[0062] In some embodiments, the translation component 200 is connected to a plurality of clamping components 400, and the rotation component 300 is connected to the base 100. The translation component 200 drives the plurality of clamping components 400 to move along the axial direction of the main shaft 310, which can also achieve the above-mentioned function.

[0063] In this embodiment, the translation component 200 is connected to the rotation component 300, eliminating the need to move the wire feeding component 500 and multiple clamping components 400, making the overall structure of the winding machine more compact, simple, and easy to maintain.

[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
