Description

Technical Field

[0001] This invention relates to the field of winding device technology, specifically to an ultrafine wire winding device. Background Technology

[0002] The intertwining of strands to form a wire harness is a widely used method in actual production. Most wire harnesses on the market are made by manually winding or winding machines using large-diameter strands. However, for ultrafine strands with small diameters, stress is easily generated during placement and transmission due to the small diameter of the strands. Furthermore, the synchronization of the feeding process of each strand in traditional winding devices is difficult to maintain, resulting in inconsistent feeding speeds of individual strands. This leads to bending, twisting, and stress in the finished wire harness. Summary of the Invention

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] like Figures 1-3 As shown, an ultrafine wire winding device includes a worktable 1, a wire feeding module 2, a forming module 3, a speed control module 4, and a wire take-up module 5 mounted on the worktable 1. The wire feeding module 2 is located at the bottom of the worktable and is used to provide multiple bundles of wire to be wound. The forming module 3 is located above the wire feeding module 2 and is used to constrain and shape the wires. The speed control module 4 is located above the forming module 3 and is used to adjust the speed of wire feeding and take-up. The wire take-up module 5 is located above the speed control module 4 and is used to wind up the wire bundle and arrange it.

[0038] The wire feeding module 2 includes a first rotary drive 21, a first drive shaft 22, and several wire feeding assemblies 23. The output end of the first rotary drive 21 is connected to the lower end of the first drive shaft 22 via a belt. The first drive shaft 22 is a hollow structure. The top end of the first drive shaft 22 is provided with a first fixing plate 221. The first fixing plate 221 has a first center line hole 223 in the middle. The first center hole is connected to the inside of the first drive shaft 22 for conveying the center line to be wound. Several wire feeding assemblies 23 are disposed on the first fixing plate 221 and are movably connected to the first fixing plate 221. The first drive shaft 22 is fitted with a first bushing 224. The first bushing 224 is fixedly connected to the worktable 1, and the first drive shaft 22 is movably connected to the first bushing 224. The first drive shaft 22 is provided with a first drive wheel 222. In use, the first rotary drive 21 drives the first drive shaft 22 and the first drive wheel 222 to rotate. Then, the first drive wheel 222 drives several wire feeding assemblies 23 to rotate synchronously via a belt. The number of wire feeding components 23 is determined according to the actual winding requirements. In this invention, the number of wire feeding components 23 is six.

[0039] Please combine Figure 4 The wire feeding assembly 23 includes a wire feeding shaft 231, a wire feeding shaft fixing plate 232, and several second transmission wheels 233. The second transmission wheels 233 are fixedly installed at the lower end of the wire feeding shaft 231. The second transmission wheels 233 achieve synchronous movement with the first transmission wheel 222 through a belt. Each adjacent wire feeding assembly 23 is connected to the second transmission wheel 233 through a belt, thereby achieving synchronous movement of each wire feeding assembly. The wire feeding shaft fixing plate 232 is installed at the upper end of the wire feeding shaft 231. The surface of the wire feeding shaft fixing plate 232 is provided with a circular groove 2321. Several fixing grooves 2322 are radially provided on the outer side of the circular groove 2321. The fixing grooves 2322 are connected to the circular groove 2321. A first connecting member 2323 is provided between the second transmission wheel 233 and the pay-off shaft fixing plate 232. The first connecting member 2323 is fixedly connected to the first fixing plate 221. The first connecting member 2323 improves the smoothness between the pay-off shaft 231 and the first fixing plate 221, and also helps to improve the smoothness during use. In use, the spool to be wound with the strand to be wound is sleeved on the pay-off shaft 231 and fixed by the circular groove 2321 and the fixing groove 2322. The upper and lower ends of the pay-off shaft 231 are provided with threaded structures. The threaded structure at the upper end of the pay-off shaft 231, together with the nut, fixes the raw material, further improving the stable connection between the spool to be wound and the pay-off shaft 231.

[0040] Please combine Figure 5An outer cover assembly 6 is fixedly installed on the first fixing plate 221 of the wire feeding shaft. The outer cover assembly 6 includes a protective cover 61, a connecting rod 62, and a connecting plate 63. The protective cover 61 is fixedly connected to the first fixing plate 221. The top of the protective cover 61 is provided with six first wire feeding holes 611. The first wire feeding holes 611 are located at the upper end of the wire feeding shaft rod 231. The center of the top of the protective cover 61 is provided with a second center line hole 612. The connecting rod 62 is installed on the top of the protective cover 61. The connecting plate 63 is fixedly connected to the connecting rod 62. The outer side of the connecting plate 63 is provided with six second wire feeding holes 631. The center of the connecting plate 63 is provided with a third center line hole 632. The third center line hole 632 passes through the connecting rod 62 and communicates with the second center line hole 612. The center wire to be wound passes sequentially through the first center wire hole 223, the second center wire hole 612, and the third center wire hole 632 before being conveyed to the forming module 3. Each strand of wire passes sequentially through the first wire release hole 611 and the second wire release hole 631 before being conveyed to the forming module 3. In this invention, the outer cover assembly 6 has a circular structure. On one hand, the overall circular shape of the outer cover assembly 6 effectively reduces wind speed during operation. By reducing wind resistance and weight during high-speed operation, it effectively reduces driving energy, thereby achieving energy saving in the production process. On the other hand, by setting the outer cover assembly 6, it ensures that the winding drum is not affected by external factors during use, preventing defects in the finished product processing.

[0041] The wire feeding module 2 in this invention drives the wires to move synchronously through the synchronous transmission of the first transmission shaft 22 and the wire feeding assembly 23. This can effectively eliminate the stress generated by the ultra-fine wires themselves during the production process such as twisting. It provides fully automatic winding operation while ensuring that the ultra-fine wires will not break due to stress during the production process. The finished wire harness will not bend or twist in the later stage, which greatly improves the product yield and work efficiency.

[0042] Please combine Figures 6-7 The molding module 3 includes a first mounting frame 31, a second connecting member 32, and a molding die 33. The first mounting frame 31 is fixedly connected to the worktable 1, and the second connecting member 32 is screwed to the first mounting frame 31. The second connecting member 32 is provided with a molding groove 321, and the molding die 33 is installed in the molding groove 321. The molding die 33 has a molding hole 331 in the middle, which has a funnel-shaped structure. After the wires are rotated around the center line and each strand, a wire harness is formed. The regularity of the strands and the center line can be adjusted by adjusting the connection height between the second connecting member 32 and the first mounting frame 31. The funnel-shaped molding hole 331 on the molding die 33 constrains and shapes the wire harness.

[0043] Please combine Figure 8The speed control module 4 includes a second mounting bracket 41, an upper guide wheel 42, a take-up roller 43, and a potentiometer 44. The second mounting bracket 41 is fixedly connected to the worktable 1. The upper guide wheel 42 is mounted on the front end of the second mounting plate, and the potentiometer 44 is mounted on the rear end of the second mounting plate. The take-up roller 43 is located between the upper guide wheel 42 and the potentiometer 44. The output end of the potentiometer 44 is connected to a swing arm 45, and a lower guide wheel 46 is connected to the swing arm 45. The lower guide wheel is located at the lower end of the upper guide wheel 42. The potentiometer 44 is electrically connected to the take-up module 5. In use, the wire harness coming out of the forming module 3 passes through the upper guide wheel 42 and the take-up roller 43 multiple times in sequence, and then is conveyed to the take-up module 5 via the lower guide wheel. The upper guide wheel 42 and the take-up roller 43 provide traction force for the wire harness. In addition, potentiometer 44 is connected to lower guide wheel 46 via swing arm 45. Since the wire feeding speed of the wire harness is fixed, when the winding speed in the take-up module 5 is faster than the wire feeding speed of the wire harness, the swing arm 45 moves upward and drives potentiometer 44 to rotate. At this time, potentiometer 44 transmits a signal to the take-up module 5 and adjusts the take-up speed. Therefore, the winding speed of the wire harness can be dynamically adjusted by potentiometer 44.

[0044] Please combine Figure 9 Above the speed control module 4 is a take-up module 7, which includes a third rotary drive 71 and a take-up rod 72. The third rotary drive 71 is fixedly installed on the workbench 1 and is driven to connect with the take-up rod 72. By adding the take-up module 7, sufficient traction is provided for the wire harness.

[0045] Please combine Figure 10 The lower end of the take-up module 5 is provided with a sorting module 8. The sorting module 8 includes a fourth rotary drive 81, a second fixed plate 82 and a sorting rod 83. The fourth rotary drive 81 is fixedly installed on the workbench 1. The bottom end of the second fixed plate 82 is provided with a rack 84. The output end of the fourth rotary drive 81 is provided with a gear that matches the rack 84. The workbench 1 is provided with a slide rail that matches the second fixed plate 82 to improve the smoothness of the movement of the second fixed plate 82. The sorting rod 83 is fixedly installed on the second fixed plate 82. The fourth rotary drive 81 drives the sorting rod 83 to move, thereby driving the movement of the wire harness.

[0046] Please combine Figure 11 The take-up module 5 includes a second rotary drive 51, a third mounting bracket 52, and a winding drum 53. The second rotary drive 51 and the third mounting bracket 52 are both mounted on the workbench 1. The winding drum 53 is movably connected to the third mounting bracket 52. The second rotary drive 51 drives the winding drum 53 to rotate via a belt.

[0047] Workflow: The strand to be wound and the center line are conveyed to the forming module by the wire feeding module. After being rotated as a whole in the wire feeding module, the strand is wound in the forming module to form a wire harness. After the conveying speed is regulated by the speed control module, the wire harness passes through the take-up module and the sorting module, and finally passes through the take-up module to complete the winding and sorting of the wire harness.

[0048] Compared with existing technologies, this invention completes the fully automatic winding operation of multi-strand wires into wire bundles by setting up a wire feeding module, a forming module, a speed control module, and a wire take-up module. In the wire feeding module, the first drive shaft drives the wire strands synchronously through synchronous transmission with the wire feeding component, effectively eliminating the stress generated during production twisting and other processes. While providing fully automatic winding operation, it also ensures that the ultra-fine wires will not break due to stress during production, and that the finished wire bundle will not bend or twist in the later stage. At the same time, it ensures that the finished wire bundle is in a stress-free state, which greatly improves the winding effect and winding efficiency.
