AI Technical Summary
In the existing technology, the wire feeding reel rotates more due to inertia, resulting in inaccurate control of the wire length and reduced precision of the cutting length. The existing technology for wire feeding cannot accurately control the cutting length, leading to wire accumulation and inaccurate cutting, increasing the defect rate and production costs.
A tensioning device, which includes pulley blocks sliding on slide bars, is used to control the wire length between the main pulley block and the driven pulley block. This is achieved by combining the rotation of the drive shaft and the driven shaft with limit and protection rollers, thus preventing wire accumulation.
This improved the accuracy of wire cutting length, reducing the defect rate and production costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal wire harness processing, and more specifically to a wire conveying device for terminal wire harness processing. Background Technology
[0002] With the development of technology, electronic devices play an increasingly important role in people's lives. Terminal wire harnesses are an indispensable part of electronic devices, used to transmit power, data, and other signals. A terminal wire harness is composed of metal terminals and wires. In the manufacturing process, the wires wound on a spool are first cut to a certain length. Then, the protective sheath at the ends of the cut wires is removed, exposing the conductive metal wires. Finally, the metal terminals are connected to the conductive metal wires to form the terminal wire harness. Currently, when pulling the wires wound on the spool, it is impossible to accurately control the number of rotations of the wire feed spool. This causes the spool to rotate more due to inertia, increasing the length of the wire fed. During the cutting process, excess wire accumulates forward, reducing the accuracy of the cutting length and even causing folding during cutting, resulting in defective products, wasted wire, and increased production costs. Summary of the Invention
[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a wire feeding device for terminal wire harness processing, which can accurately control the wire feeding length of the wire feeding reel, avoid wire accumulation, improve the accuracy of wire cutting length, reduce the defect rate, and reduce production costs.
[0004] To address the aforementioned technical problems, the objective of this application is achieved through the following technical solution: a wire feeding device for terminal wire harness processing, comprising a base, a support frame mounted on the base, and a control box. The support frame is equipped with a wire feeding reel for winding the wire. The control box is equipped with a wire threading tensioning device. The tensioning device includes a slide bar mounted on the control box, a main pulley assembly located at the top of the slide bar on the control box, and a driven pulley assembly slidably connected to the slide bar. The driven pulley assembly is driven by the control box to slide on the slide bar. The wire is threaded through the main pulley assembly and the driven pulley assembly. By controlling the sliding of the driven pulley assembly on the slide bar, the length of the wire between the main pulley assembly and the driven pulley assembly is controlled, thereby accurately controlling the wire feeding length of the wire feeding reel. Controlling the tension of the wire between the main pulley assembly and the driven pulley assembly prevents wire accumulation, improves the accuracy of wire cutting length, reduces the defect rate, and lowers production costs.
[0005] Preferably, the support frame has a drive shaft on the left side, controlled by a control box, and a driven shaft on the right side, corresponding to the drive shaft. The wire feed reel is mounted on both the drive and driven shafts. Protective rollers are also provided at both ends of the support frame. The control box controls the drive shaft to rotate the wire feed reel, thus feeding the wire. The driven shaft rotates accordingly. The reverse rotation of the drive shaft can also act as a brake and a return mechanism, further preventing wire accumulation. The protective rollers can protect and limit the wire feed reel, preventing it from rolling out of the support frame.
[0006] Preferably, the control box is equipped with control buttons and a display panel for easy control of the wire feeding speed.
[0007] Preferably, the main pulley assembly is provided with a first connecting plate, and the outer end of the first connecting plate is provided with a first pressure rod that abuts against the wire.

[0008] Preferably, the pulley block is provided with a second connecting plate, and the outer end of the second connecting plate is provided with a second pressure rod that abuts against the wire. The pulley block is provided with a slider that slides against the slider. The second pressure rod limits the wire to prevent the wire from shifting and getting tangled on the pulley block, ensuring the normal operation of the wire feeding; the sliding of the pulley block on the slider is achieved through the cooperation of the slider and the slider.
[0009] Preferably, the side of the control box is provided with a support plate parallel to the slide bar, and the support plate is provided with a plurality of sensors that sense the position of the pulley group. The sensors are connected to the control box. The sensors sense the position of the pulley group and transmit a signal to the control box. The control box receives the signal and controls the length of the wire between the main pulley group and the pulley group, thereby enabling accurate control of the wire feeding length of the wire feeding reel.
[0010] Preferably, the control box is equipped with a limiting device on the front side of the main pulley assembly to limit the movement of the wire. This prevents the wire from shifting and getting tangled on the main pulley assembly, ensuring the normal operation of the wire feeding system.
[0011] Preferably, the limiting device includes an L-shaped frame mounted on the control box, a slide groove mounted on the L-shaped frame, and two limiting rods mounted in the slide groove, with the wire positioned between the two limiting rods. This design features a simple structure, good limiting effect, and adjustable distance between the two limiting rods, making it suitable for limiting wires of different diameters.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] The wire feeding device for terminal wire harness processing using the above technical solution controls the length of the wire between the main pulley group and the secondary pulley group by sliding the secondary pulley group on the slide bar, thereby accurately controlling the wire feeding length of the wire feeding reel; controlling the tension of the wire between the main pulley group and the secondary pulley group can prevent wire accumulation, improve the accuracy of wire cutting length, reduce the defect rate, and reduce production costs.
