[0002] Multi-wire wound medical springs are commonly used in various medical devices, such as endoscopes, surgical instruments, pacemakers, and implantable medical devices. These medical devices require springs to provide support, guidance, or connection. Multi-wire wound medical springs also have a wide range of applications in medical equipment, such as valves and connectors in ventilators, extracorporeal circulation equipment, and infusion pumps. In medical syringes, multi-wire wound medical springs can be used to control the piston movement of the syringe to ensure accurate drug delivery.
[0003] Currently, existing equipment faces several technical challenges that lead to instability or failure in multi-wire winding: in terms of tension control, it is impossible to accurately control the tension of multiple strands of wire; and in terms of winding path control, fine wires are prone to crossing, tangling, or breaking.

[0014] (1) The multi-wire parallel winding precision spring winding equipment controls multiple strands of wire separately in terms of tension control to meet the tension requirements of wires of different material specifications. It accurately controls the tension of each filament to ensure that the tension of each filament is uniform and stable, so as to ensure that the quality of the wound spring is consistent.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0026] Please see Figure 1-4 This utility model provides a technical solution: a precision spring winding device for multiple wires, including a spring winding base 1, a support frame 2 fixedly connected to the top of the spring winding base 1, a wire spool 3 inside the support frame 2, and a winding roller 4 rotatably connected to the top of the support frame 2.
[0027] Among them, a tension control plate 5 is fixedly installed on the top of the spring base 1, and a winding bottom wheel 6 is rotatably connected to the lower end of the tension control plate 5.
[0028] Among them, the surface of the tension control plate 5 is rotatably connected to the rotating wheel 7;
[0029] Among them, the surface of the tension control plate 5 is rotatably connected to the feeding device rod 8, and the surface of the feeding device rod 8 is fixedly connected to the tension spring 9.
[0030] Among them, a fixing block 10 is fixedly connected to the surface of the tension control plate 5, and the end of the tension spring 9 away from the feeding device rod 8 is fixedly connected to the surface of the fixing block 10.
[0031] The top of the spring base 1 is fixedly connected to a wire divider 11, and a locking block 12 is slidably connected inside the wire divider 11. The right end of the locking block 12 is rotatably sleeved with a wire divider disc 13.
[0032] When using this multi-wire precision spring winding equipment, the operator first winds multiple strands of wire onto the surface of the wire distribution plate 13. Then, the wire is wound around the winding bottom wheel 6 and then wound upwards onto the surface of the rotating wheel 7. After passing through the feeding device rod 8, it moves upwards and finally winds the wire onto the surface of the wire reel 3 via the winding roller 4. At this time, the rotation of the wire reel 3 allows the wire to be wound on its surface. The feeding device rod 8 provides a continuous supply of wire, ensuring the continuity and stability of the winding process. Multiple wire feeding rods are used to feed the wire separately, and the wire supply speed is precisely controlled to ensure that the winding length of each filament is consistent and to avoid uneven winding.
[0033] Tension control during the winding process is provided by tension spring 9. In terms of tension control, multiple strands of wire are controlled separately to meet the tension requirements of wires of different material specifications. The tension of each filament is precisely controlled to ensure that the tension of each filament is uniform and stable, so as to ensure that the quality of the wound spring is consistent. In terms of wire path control, a wire diversion device is used to separate the paths of the wires, precisely control the winding path of each filament, avoid the filaments crossing, tangling or breaking, and ensure that the wound spring has a compact and uniform structure.
[0034] The left end of the locking block 12 is threaded with a screw 14.
[0035] After the operator rotates the screw 14 and disengages it from the surface of the clip 12, the clip 12 can be disassembled. The operator can then slide the clip 12 out of the inside of the wire divider 11 to disassemble the wire divider disc 13, thus improving the ease of disassembly and installation of the wire divider disc 13 and making it easier for the operator to replace the wire divider disc 13.
[0036] Working principle: In this multi-wire precision winding spring device, the operator first winds multiple strands of wire onto the surface of the wire distribution plate 13. Then, the wire is wound around the winding base wheel 6 and then wound upwards onto the surface of the rotating wheel 7. After passing through the feeding device rod 8, it moves upwards. Finally, the wire is wound onto the surface of the wire reel 3 via the winding roller 4. At this time, the rotation of the wire reel 3 allows the wire to be wound on its surface. The feeding device rod 8 provides a continuous supply of wire, ensuring the continuity and stability of the winding process. The tension is controlled by the tension spring 9, ensuring the stability and consistency of the wire. This allows for precise control of the tension of the multiple strands of wire. The operator can disassemble the clamp 12 by rotating the screw 14 and disengaging it from the surface of the clamp 12. The operator can also disassemble the wire distribution plate 13 by sliding the clamp 12 out of the wire distributor 11, thus improving the convenience of disassembling and installing the wire distribution plate 13.
[0037] 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 scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
