Abstract
Description
Technical Field
[0001] This invention relates to the field of electromagnet manufacturing technology, and in particular to a magnet winding device and fixture. Background Technology
[0002] Electromagnets, used in particle accelerators and high-end medical equipment, are core components ensuring equipment performance. The quality of their magnetic field directly depends on the winding precision of the coil. Therefore, the winding process of the magnet coil and the fixtures used play a decisive role in the final product performance. However, in their review and analysis of existing technologies, the inventors discovered that traditional magnet winding methods have revealed several bottlenecks that urgently need to be addressed when facing increasingly stringent technical specifications. First, the methods for controlling wire tension are rudimentary, resulting in poor quality consistency. Second, the insulation layer coating process is disconnected from the winding process, making it difficult to balance efficiency and reliability. Third, the cumbersome method of changing fixtures for different magnet types severely restricts production flexibility.
[0003] Specifically, in existing processes, operators typically apply tension by feel or with the aid of simple mechanical friction devices when controlling conductor tension. This method cannot guarantee constant tension throughout the winding process. Especially during equipment start-up, shutdown, acceleration, and deceleration, the tension fluctuates drastically. This directly leads to uneven stress distribution within the coil, with occasional tiny gaps between the turns and periods of excessive compression, ultimately affecting the dimensional accuracy and magnetic field uniformity of the finished product, failing to meet the stringent requirements of high-energy physics research.
[0004] Insulation treatment is another prominent technical challenge. The common practice is to pre-wrap the insulation tape independently around the entire coil of wire, forming a pre-insulated wire bundle. This process itself consumes a significant amount of time. More seriously, this pre-insulated wire bundle must undergo prolonged guiding, bending, and friction with the mold during subsequent winding. This condition easily leads to scratches and fraying of the insulation surface, and even stretching and displacement of the insulation tape at bends, creating a potential electrical breakdown hazard for the long-term stable operation of the coil.
[0005] In production practice, it is often necessary to complete the winding of magnets of various specifications on a single machine. This means that the winding fixture needs to be changed frequently. Traditional equipment mostly uses bolts to directly fix the fixture. The entire replacement process is extremely cumbersome, requiring workers to spend a lot of time tightening and loosening the bolts one by one. The fixture itself is usually quite heavy, and handling and alignment are not only labor-intensive but also pose safety risks. More importantly, it is difficult to guarantee that each manual alignment will be completely consistent with the previous one. Summary of the Invention

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be further described in detail below.
[0023] This invention provides a magnet winding device, comprising: a workbench 1, a controller 2 fixed to the outer wall of the workbench 1, a reducer 3 fixed inside the workbench 1, a motor 4 fixed to the input end of the reducer 3, a turntable 5 fixed to the output end of the reducer 3, and a fixed base 7 fixed to the outer side of the workbench 1; and an adjustment assembly 8, which is mounted on the fixed base 7. The adjustment assembly 8 includes a support block 801, an electric push rod 802 fixed to the outer wall of the support block 801, a fixed frame 803 fixed to the driving end of the electric push rod 802, the lower surface of the fixed frame 803 sliding on the upper surface of the fixed base 7, and a rubber plate 804 fixed inside the fixed frame 803. The device includes symmetrically oriented support rods 805, each with a rotatable guide wheel 806 on its outer wall; a winding assembly 9, mounted on the adjusting assembly 8, is used to wind insulating tape when winding the wire harness; a sliding rod 807 is fixed to the top of each guide wheel 806; a symmetrically oriented sliding groove 808 is provided inside the top of the fixed frame 803; the outer wall of the sliding rod 807 slides inside the sliding groove 808; a symmetrically oriented support block 809 is fixed to the outer wall of the fixed frame 803; a lead screw 810 rotates inside the support block 809; the outer wall of the lead screw 810 is threadedly connected to the inside of the symmetrically oriented sliding rod 807; and a handle 811 is fixed to the end of the lead screw 810.
[0024] Specifically, the electric push rod 802 can drive the fixed frame 803 to make rapid macroscopic position adjustments, thereby ensuring that the wire feed angle can perfectly adapt to winding fixtures of different sizes, laying the foundation for high-quality winding. At the level of fine control, the operator can turn the handle 811, and through the precision transmission of the lead screw 810, drive the left and right symmetrical guide wheels 806 fixed on the sliding rod 807 to move synchronously in the groove 808 at the micrometer level. This design makes the preload applied to the wire no longer a vague empirical value, but a process parameter that can be quantified and accurately reproduced by the position of the support rod 805. At the same time, when the wire is under tension by the guide wheel 806, it is always in contact with the flexible rubber plate 804, effectively buffering tension fluctuations and avoiding damage to the surface of the wire.
[0025] Please see the appendix Figure 1 -Appendix Figure 6The winding assembly 9 includes a support plate 901, the lower surface of which is fixed to the upper surface of a support block 801. A guide sleeve 902 is fixed inside the support plate 901. An auxiliary plate 903 is rotatably mounted on the outer wall of the guide sleeve 902. A gear ring 904 is fixed on the outer wall of the auxiliary plate 903. A second motor 905 is located below the auxiliary plate 903. The outer wall of the second motor 905 is fixed to a mounting base 7. A gear 906 is fixed to the output end of the second motor 905. The gear 906 and the gear ring 904 are connected together. The gear ring 904 is meshed with a long rod 907 fixed to its outer wall. A limiting plate 908 is fixed to the outer wall of the long rod 907. An insulating pulley 909 is attached to the outer wall of the limiting plate 908. The inner wall of the insulating pulley 909 slides on the outer wall of the long rod 907. A second limiting plate 910 slides on the outer wall of the long rod 907. The second limiting plate 910 and the insulating pulley 909 are in contact. A bolt 911 passes through the inside of the second limiting plate 910. The outer wall of the bolt 911 is threaded into the inside of the insulating pulley 909.
[0026] Specifically, motor 905 is first started, and driven by the stable meshing of gear 906 and large-diameter gear ring 904, it provides smooth and powerful rotational force for the entire system. Gear ring 904 drives auxiliary plate 903 to revolve at high speed around fixed central guide sleeve 902. Stable coaxial rotation ensures that the long rod 907 attached to it can sweep across the working area with a constant radius and speed. The insulating pulley 909 clamped on the long rod 907 can thus evenly and densely wrap the insulating tape around the wire passing through guide sleeve 902. This online... The real-time wrapping method not only achieves perfect synchronization with the main winding speed through the precise control of the speed of motor 905 by controller 2, ensuring a high consistency of insulation layer stacking ratio, but also solves the major technical defects of insulation layer damage and displacement caused by friction and bending during the transportation and winding process of pre-insulated wire harnesses in traditional processes. At the same time, the insulating pulley 909 is fixed by the combination structure of limit plate 908, limit plate 910 and bolt 911, which not only ensures stability under high-speed rotation, but also makes the operation of changing the insulating tape roll extremely simple and quick.
[0027] Please see the appendix Figure 1 -Appendix Figure 10This invention provides a magnet winding fixture, which includes a locking assembly 6 disposed inside a turntable 5. The locking assembly 6 includes a fixing plate 601, the lower surface of which is fixed to the inner bottom of the turntable 5. A hydraulic rod 607 is fixed to the upper surface of the fixing plate 601, and a moving plate 609 is fixed to the driving end of the hydraulic rod 607. A plurality of limiting rods 606 are fixed to the outer wall of the moving plate 609, and each limiting rod 606 has a sliding limiting block 605. A spring 608 is sleeved on the outer wall of the hydraulic rod 607, one end of which is fixed to the upper surface of the fixing plate 601, and the other end of which is fixed to the lower surface of the moving plate 609. Multiple fixing blocks 602 are fixed on the upper surface of 601. Rotating rods 603 are rotatably mounted on the outer walls of the fixing blocks 602. Fixing blocks 604 are rotatably mounted on the ends of the rotating rods 603. The outer walls of the fixing blocks 604 are fixed to the lower surface of the limiting block 605. A cylinder 610 is fixed on the upper surface of the moving plate 609. A connecting plate 611 is fixed to the driving end of the cylinder 610. A bolt 612 is fixed inside the connecting plate 611. A pressure plate 613 is threaded to the bottom end of the bolt 612. A connecting ring 10 is attached to the outer wall of the limiting block 605. A magnetic block 11 is fixed to the outer wall of the connecting ring 10. The magnetic block 11 has various shapes, including ring, square and C-shaped.
[0028] Specifically, the hydraulic rod 607 provides a powerful and stable initial force, driving the moving plate 609 upward. This not only compresses the spring 608 used for rapid reset, but more importantly, it evenly transmits the force to multiple limit blocks 605 through multiple limit rods 606. Each limit block 605 forms a lever linkage mechanism with the rotating rod 603 through the second fixed block 604. This mechanism pivots around the first fixed block 602 fixed on the base plate 601, converting the vertical movement of the limit rods 606 into the outward radial expansion of the limit blocks 605. This ensures that the connecting ring 10, which is loaded with various shaped magnetic blocks 11, is firmly supported from the inside and automatically aligned with the rotation center of the turntable 5 in an absolutely synchronized manner. This design ensures extremely high repeatability and clamping force. On this basis, the cylinder 610 located above the moving plate 609 can also drive the connecting plate 611 and the pressure plate 613 fixed by the first bolt 612 to perform a secondary downward locking, providing an additional and independent fixing point for the starting end of the wire during the winding process.
[0029] Working principle: When the winding operation is performed, the controller 2 first drives the hydraulic rod 607 in the locking assembly 6 to lift the moving plate 609, which compresses the spring 608 and drives multiple limit rods 606 to move upward. The limit rods 606 then drive the limit block 605. The limit block 605 causes the rotating rod 603 to pivot around the fixed block 602 through the second fixed block 604, thereby causing the limit block 605 to expand outward to clamp the connecting ring 10 containing the magnetic block 11 to be wound. Next, the wire passes through the adjustment assembly 8. At this time, the electric push rod 802 can move the fixed frame 803 to adjust the overall position. The operator turns the handle 811, which drives the sliding rod 807 fixed on the guide wheel 806 to move in the slide groove 808 through the lead screw 810. This changes the distance between the left and right symmetrical support rods 805 to adjust the clamping force of the guide wheel 806 on the wire. The wire passing through the rubber plate 804 thus obtains a precise preload. Once everything is ready, controller 2 starts motor 4, which, after being reduced in speed and increased in torque by reducer 3, drives turntable 5 to rotate stably inside workbench 1, starting to pull the wire around magnetic block 11. At the same time, motor 905, fixed on fixed base 7, drives gear 906 to mesh with gear ring 904, causing auxiliary plate 903, fixed on gear ring 904, to rotate around center guide sleeve 902 on support plate 901. The rotation of auxiliary plate 903 drives long rod 907, causing insulating pulley 909, which is fixed by limit plate 908, limit plate 910, and bolt 911, to also rotate at high speed. Thus, before the wire is pulled into turntable 5, the automatic wrapping of insulating tape is completed synchronously in winding assembly 9. Finally, the cylinder 610 on the moving plate 609 drives the connecting plate 611, causing the pressure plate 613, which is fixed by bolt 612, to press down and fix the subsequently wound wire.
