Figures 1-5 As shown, the wire winding device includes a winding mechanism 100 and a traction mechanism 200. The winding mechanism 100 includes a winding assembly 110, a support 120, and a wire storage tray 130. The support 120 is disposed on the output end of the winding assembly 110, and the wire storage tray 130 is rotatably disposed on the support 120. The wire storage tray 130 stores a wire of a preset length, and the free end of the wire is provided with a hook. The traction mechanism 200 includes a traction motor 210, a flipping assembly 220, and a hook assembly 230. The flipping assembly 220 is disposed on the output end of the traction motor 210, and the hook assembly 230 is disposed on the output end of the flipping assembly 220. The end of the hook assembly 230 away from the hook assembly 230 is provided with a ball head 233. During the winding process, the hook of the free end of the steel wire is hooked onto the ball head 233. The traction motor 210 drives the ball head 233 to pull the free end of the steel wire to move along the circumferential direction of the steel ring 10. The winding assembly 110 drives the wire storage disc 130 to move along the annular track 20. The annular track 20 and the steel ring 10 are interlocked. Figure 2 As shown, the steel wire is wound around the steel ring 10 to ensure uniform tension of the steel wire, which can greatly reduce the time and labor costs required for manual operation and improve production efficiency and quality; and, by driving the hook assembly 230 to rotate at a first preset angle through the flipping assembly 220 to avoid the winding assembly 110, the smoothness and reliability of the steel wire winding process are ensured.

[0046] Optionally, such as Figure 3 As shown, the winding assembly 110 includes a mounting back plate 111, a planetary gear set 112, a transmission gear assembly, and a first drive motor 114. The planetary gear set 112 is mounted on the mounting back plate 111, and a bracket 120 is mounted on the output end of the planetary gear set 112. The transmission gear assembly is driven by the planetary gear set 112, and the output end of the first drive motor 114 is driven by the transmission gear assembly. The first drive motor 114 drives the transmission gear assembly to move, so that the planetary gear set 112 drives the wire storage disc 130 to move along the annular trajectory 20. The transmission structure design using the planetary gear set 112 and the transmission gear assembly enables efficient transmission within a limited space, ensuring the stability of the wire storage disc 130's movement along the annular trajectory 20.

[0047] Optionally, as shown in Figure 3 The planetary gear set 112 includes a first C-type gear 1121, a second C-type gear 1122, a first planetary gear 1123, a second planetary gear 1124, and a winding gear 1125. The first C-type gear 1121 is fixedly arranged on the mounting back plate 111, the second C-type gear 1122 is rotatably arranged on the mounting back plate 111 and coaxial with the first C-type gear 1121, the first planetary gear 1123 and the second planetary gear 1124 are spaced along the circumference of the first C-type gear 1121 and rotatably arranged on the second C-type gear 1122, at least one of the first planetary gear 1123 and the second planetary gear 1124 can be engaged with the first C-type gear 1121, the winding gear 1125 is fixedly arranged on the first C-type gear 1121, the first planetary gear 1123 and the second planetary gear 1124 are engaged with the winding gear 1125, and the support 120 is arranged on the winding gear 1125. The planetary gear set 112 is compact in structure, fully utilizes the limited space of the mounting back plate 111, realizes efficient transmission, reduces the size of the steel wire winding device, and saves production space.

[0048] It should be noted that the first C-type gear 1121 is provided with a first opening, and part of the steel ring 10 extends into the first opening, and the steel wire can be wound on the steel ring 10 when the wire storage disc 130 moves along the annular track 20. Since the first C-type gear 1121 is provided with the first opening, in order to avoid the interruption of power transmission caused by the first opening, the first planetary gear 1123 and the second planetary gear 1124 are rotatably arranged on the second C-type gear 1122 in this embodiment, and at least one of the first planetary gear 1123 and the second planetary gear 1124 is always engaged with the first C-type gear 1121, so as to realize seamless transfer of power, which ensures the stability and reliability of the steel wire winding device.

[0049] Optionally, as shown in Figure 3 The transmission gear assembly includes a first transmission gear 1131 and a second transmission gear 1132, which are spaced along the circumference of the second C-type gear 1122 and rotatably arranged on the mounting back plate 111. At least one of the first transmission gear 1131 and the second transmission gear 1132 is engaged with the second C-type gear 1122, and the first driving motor 114 is used to drive the first transmission gear 1131 and the second transmission gear 1132 to rotate synchronously. Since the second C-type gear 1122 is provided with a second opening, in order to realize the continuity and stability of the power, at least one of the first transmission gear 1131 and the second transmission gear 1132 is always engaged with the second C-type gear 1122, so as to realize seamless transfer of power. This design effectively avoids the problem of interruption of power transmission caused by the second opening, and ensures the stability of the device.

[0050] It should be noted that the first drive motor 114 can drive the first transmission gear 1131 and the second transmission gear 1132 to rotate synchronously by using a transmission belt assembly, or can drive the first transmission gear 1131 and the second transmission gear 1132 to rotate synchronously by using a plurality of power gears to mesh with each other to realize power transmission. The structure of the transmission belt assembly and the plurality of power gears is a prior art, and will not be described here.

[0051] Optionally, as shown in Figure 4 The hook assembly 230 is connected to the output end of the rotating disc 221. The rotating disc 221 is provided on the output end of the traction motor 210. The overturning motor 222 is provided on the rotating disc 221 at a second preset angle. The overturning motor 222 is used to drive the hook assembly 230 to overturn by a first preset angle, thereby reducing the operation conflict between components and ensuring the stability and reliability of the device.

[0052] Optionally, the overturning assembly 220 further comprises a wedge-shaped pad 223. The wedge-shaped pad 223 is provided on the rotating disc 221. The overturning motor 222 is provided on the inclined surface of the wedge-shaped pad 223. The installation angle of the overturning motor 222 can be effectively adjusted to better meet the actual working requirements, thereby ensuring smooth and efficient power transmission between the overturning motor 222 and the hook assembly 230.

[0053] Optionally, the hook assembly 230 comprises a first swing arm 231 and a second swing arm 232. One end of the first swing arm 231 is connected to the output end of the overturning assembly 220. The other end of the first swing arm 231 is connected to the second swing arm 232. The second swing arm 232 is provided with a ball head 233 at an end away from the first swing arm 231. The first swing arm 231 and the second swing arm 232 are provided at a preset included angle. The force transmission path in the hook assembly 230 is effectively optimized. The load of the force acting on the hook assembly 230 from the output end of the overturning assembly 220 is reduced. The force transmission efficiency is improved. The overall mechanical wear is reduced.

[0054] It should be noted that, as shown in Figure 4 and Figure 5 Before and after the overturning assembly 220 drives the hook assembly 230 to overturn, the position of the ball head 233 relative to the steel ring 10 remains unchanged. The traction path of the steel wire is ensured not to deviate. The problem of uneven tension or misalignment of the steel wire due to path change is avoided. The uniformity and tightness of the steel wire winding on the steel ring 10 are ensured.

[0055] Optionally, the second swing arm 232 is configured as an arc structure, and the radius of the second swing arm 232 is the same as the radius of the ring 10, so that the hook assembly 230 can run close to the surface of the ring 10 when the steel wire is pulled, ensuring that the steel wire is fully matched with the surface of the ring 10 when winding, thereby improving the uniformity and tightness of the steel wire winding.

[0056] Optionally, the first swing arm 231 and the second swing arm 232 are detachably connected, so that when a part of the hook assembly 230 is worn or fails, the damaged part can be replaced individually without replacing the entire hook assembly 230, thereby reducing maintenance cost and maintenance difficulty. Moreover, the first swing arm 231 and the second swing arm 232 can be manufactured individually, thereby reducing the precision requirement and assembly complexity, improving production efficiency and reducing manufacturing cost.

[0057] The steel wire winding device provided in the embodiment has the following winding process:

[0058] First, the ring 10 is fixed on a C-shaped ring (not shown in the figure), and the C-shaped ring is used to support the ring 10.

[0059] Then, the hook of the free end of the steel wire is hung on the ball head 233 of the hook assembly 230, at this time the traction motor 210 of the traction mechanism 200 starts to rotate clockwise, the hook assembly 230 drives the steel wire hook to rotate along the ring 10, the first drive motor 114 of the winding assembly 110 starts to move, drives the planetary gear set 112 to rotate, and the wire storage disc 130 installed on the planetary gear set 112 moves along the annular track 20, the steel wire in the wire storage disc 130 is driven by the hook assembly 230 and wound on the ring 10.

[0060] When the hook assembly 230 on the traction mechanism 200 approaches the planetary gear set 112 of the winding assembly 110, in order to prevent interference, the overturning motor 222 of the traction mechanism 200 is instantaneously overturned, the hook assembly 230 installed on the output shaft of the overturning motor 222 is overturned to the overturned position, so that the hook assembly 230 on the traction mechanism 200 does not interfere with the planetary gear set 112; when the hook assembly 230 of the traction mechanism 200 is away from the vicinity of the planetary gear set 112, the overturning motor 222 is instantaneously overturned again, the hook assembly 230 installed on the output shaft of the overturning motor 222 is overturned to the initial position, and the cycle is repeated until the steel wire in the wire storage disc 130 is used up; at this time, the traction motor 210 of the traction mechanism 200 continues to rotate clockwise at a small angle, the steel wire hook on the traction mechanism 200 is pulled straight, the ball head 233 is directly separated from the steel wire, and the winding action is completed.

[0061] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
