Description

Technical Field

[0001] This utility model relates to the field of stranded wire processing technology, and more specifically, to an automatic unwinding machine for finished stranded wires. Background Technology

[0002] Stranded wire is a composite conductor formed by twisting or winding multiple small-diameter wires. Its structural characteristics give it superior flexibility and conductivity compared to solid wires of the same cross-sectional area due to its larger total surface area. This larger surface area reduces metal fatigue and stress, making it suitable for applications such as printed circuit board equipment and musical instrument cables. However, some materials require that the strand pitch not change after unwinding, and that the wire cannot be dragged or tossed during cutting and unwinding. Furthermore, the overall structure of the conductor must not be altered after unwinding, and there must be no compression or bending during the unwinding process. Currently, there is no dedicated equipment in the wire harness industry capable of unwinding these special requirements, necessitating manual cutting. Therefore, we have proposed an automatic unwinding machine for finished stranded wires. Utility Model Content

[0003] In view of the problems mentioned in the background art above, the purpose of this utility model is to provide an automatic unwinding machine for finished stranded wires.

[0004] To solve the above problems, this utility model adopts the following technical solution: an automatic unwinding machine for finished stranded wire, including a wire feeding box, a wire straightening mechanism on the side of the wire feeding box, a wire cutting mechanism on the side of the wire straightening mechanism, a wire feeding groove mechanism on the side of the wire cutting mechanism, a wire feeding frame at the bottom of the inner cavity of the wire feeding box, a first chuck rotatably connected to one side of the wire feeding frame, a cylinder fixedly installed on the other side of the wire feeding frame, a second chuck rotatably connected to the output shaft of the cylinder through a bearing, a wire reel between the second chuck and the first chuck, a first reduction motor fixedly installed at the bottom of the inner cavity of the wire feeding box, a synchronous pulley fixedly sleeved at one end of the output shaft of the first reduction motor and one end of the rotating shaft of the first chuck, a synchronous belt drivingly connecting the two synchronous pulleys, a material support mechanism on the wire feeding box, a wire threading hole at the top of the wire feeding box, a support frame fixedly connected to the top of the wire feeding box, and a first wire pulley rotatably connected to the side of the top of the support frame.

[0005] As a preferred embodiment of this utility model, the conductor straightening mechanism includes a straightening box disposed on the side of the wire feeding box. A straightening wheel bracket is provided inside the straightening box. A front conductor straightening wheel is rotatably connected to both the upper and lower parts of the straightening wheel bracket. A limit guide roller is provided on one side of the straightening box. A one-way conductor straightening wheel is rotatably connected to the other side of the straightening box via a one-way bearing. A high-strength spring is fixedly connected to the other side of the straightening box. A rotating base is fixedly connected to the bottom end of the high-strength spring. A pressing wheel is rotatably connected to the front side of the rotating base. Two second sliders are fixedly connected to the back of the rotating base. Two second sliding rods are fixedly connected to the side of the straightening box. The second sliding rods and second sliders are movably sleeved together.

[0006] As a preferred embodiment of this utility model, the wire cutting mechanism includes a cutting table disposed on the side of the straightening box, a mounting frame fixedly connected to the cutting table, a wire shortage sensor disposed on the top surface of the mounting frame, a wire rear straightening wheel disposed on the top of the mounting frame, a wire length detection sensor pressure wheel disposed on the top of the mounting frame, a wire fixing flexible gripper disposed on the cutting table, a wire guide disposed on the cutting table, and a pneumatic cutter disposed on the cutting table.

[0008] As a preferred embodiment of this utility model, the material support mechanism includes a second reduction motor fixedly installed at the bottom of the inner cavity of the wire feeding box. The output shaft of the second reduction motor is fixedly connected to a screw. A lifting seat is threaded onto the outer side of the screw.

[0010] The advantages of this utility model are: (1) In this utility model, synchronous wire feeding is adopted when feeding wire. When the machine gripper clamps the end of the wire, the system will feed wire synchronously back and forth according to the set wire length, so that the wire is fed without resistance. When the set length is reached, the feeding stops and the cutting action begins. The gripper is made of soft rubber material, so there is no squeezing or bending of the wire when it is clamped. The synchronous wire feeding and flexible gripper ensure that the wire itself is not affected. The wire does not change after cutting, ensuring that the twist pitch remains unchanged after the wire is fed.

[0011] (2) In this utility model, an automated equipment is made to perform automatic unloading operations, which simplifies the traditional complex process, completes wire cutting quickly and accurately, greatly improves the operation speed, can adapt to different wire length requirements, flexibly adjusts operation parameters, reduces uncontrollable factors of manual operation, ensures consistent production parameters, and realizes synchronous wire feeding, flexible wire clamping, and consistency of twist pitch before and after unloading for the special requirements of the wire.
