[0002] During the production of wire harnesses, the ends of the wire harnesses need to be tinned. Generally, there is only one core wire in the wire harness, so the tinning process can be well completed by simply inserting the end of the wire harness into the tin liquid. However, for wire harnesses with multiple core wires inside, since the tube sleeves wrapping the core wires at the ends of the wire harnesses are cut off, the core wires at the ends are prone to looseness, which will cause the wire harnesses after tinning to fail to meet the requirements, affecting the subsequent assembly and use of the wire harnesses. Therefore, it is necessary to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0029] As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0030] like Figure 1As shown, a device for producing a wiring harness includes a twisting mechanism arranged on a frame to twist the ends of the stripped wire segments. The terminal punching mechanism 20, the stripping mechanism 30, the dip agent mechanism 60, and the tinning mechanism 70 are sequentially arranged on the frame 00 along the X direction, and the transfer mechanism 50 is installed on the second movable mounting seat 56. The first movable mounting seat 11 and the second movable mounting seat 56 are movably installed along the X direction, and the X direction is the horizontal direction. The cutting mechanism 40 can be installed between the terminal punching mechanism 20 and the stripping mechanism 30, and can also be installed in other positions according to specific implementation requirements.

[0031] The operation of producing a harness using the above-mentioned equipment is as follows: the wire is released by the wire release mechanism 10, and the end of the wire is peeled, and the peeled end is terminalized; the terminalized wire is cut into wire segments 01, the other end of the wire segment 01 is peeled, and then the other end of the wire segment 01 is sequentially treated with a dip agent and tinning, and after the tinning treatment, the prepared wire segment 01 is unloaded by the unloading mechanism 80 to obtain the wire, such as Fig.11 As shown; the thickness of the wire is such that the wire segment 01 obtained by the cutting process will not bend in the naturally suspended state. The wire segment 01 after the cutting process is transported by the transfer mechanism 50, and the transfer mechanism 50 transports the wire segment 01 to the peeling mechanism 30, the dipping agent mechanism 60, and the tinning mechanism 70 for corresponding processing. The wire release mechanism 10 is installed on the first movable mounting seat 11, and the first movable mounting seat 11 is adjusted to move so that the wire release mechanism 10 is arranged correspondingly to the peeling mechanism 30, the terminal crimping mechanism 20 and the cutting mechanism 40 for corresponding processing.

[0032] like Figure 2As shown, the first movable mounting seat 11 and the second movable mounting seat 56 are respectively arranged on the two outer sides of the peeling mechanism 30 (cutting mechanism 40). The wire-releasing mechanism 10 also includes a wire coil assembly component for assembling the wire coil and a wire-releasing component for pulling the wire for release and conveying. The wire-releasing component includes a first clamping conveyor belt 12 and a second clamping conveyor belt 13 which are arranged relatively to each other on a first movable mounting seat 11. The belt surfaces of the first clamping conveyor belt 12 and the second clamping conveyor belt 13 are arranged vertically. The wire is clamped, pulled and conveyed by the first clamping conveyor belt 12 and the second clamping conveyor belt 13 along the Y direction. The Y direction is a horizontal direction perpendicular to the X direction. The first movable mounting seat 11 is also provided with two vertically arranged wire boards 15 and a wire tube 16 cantilevered along the Y direction. The wire board 15 is provided with a wire hole for the wire to pass through. The two wire boards 15 are respectively disposed on the outer sides of the ends of the first clamping conveyor belt 12 and the second clamping conveyor belt 13. The guide tube is disposed on the outer sides of the unloading ends of the first clamping conveyor belt 12 and the second clamping conveyor belt 13.

The arrangement of the wire plate 15 can effectively prevent the wire from running off and ensure the reliability of the wire harness transportation. The arrangement of the overhanging wire tube 16 can facilitate the subsequent processing of the wire. The wire hole on the wire plate 15 and the tube cavity of the wire tube 16 are arranged concentrically and are arranged in the middle of the bandwidth of the first pinching conveyor belt 12 and the second pinching conveyor belt 13.

[0033] The first clamping conveyor belt 12 and the second clamping conveyor belt 13 have the same structure. The first clamping conveyor belt 12 includes pulleys respectively arranged at both ends and a conveyor belt body sleeved on the pulleys. A guide auxiliary wheel 14 is arranged on the inner side of the belt body section for clamping the wire on the conveyor belt body. The guide auxiliary wheels 14 are arranged at intervals along the length direction of the belt body section. During specific operation, the pulleys and the guide auxiliary wheels 14 are both toothed pulleys, and the conveyor belt body is a (single-sided) toothed conveyor belt. The guide auxiliary wheels 14 arranged at intervals can better clamp and traction the wire to prevent the wire from running off or falling between the first clamping conveyor belt 12 and the second clamping conveyor belt 13, thereby ensuring the reliability of the wire traction and transportation.

[0034] The first movable mounting seat 11 is slidably mounted on the first guide rail provided on the first bracket 17 along the X direction, and the first bracket 17 is slidably mounted on the frame 00 along the Y direction. By adjusting the first movable mounting seat 11 to move along the X direction, the wire-releasing assembly is adjusted to be arranged correspondingly with the cutting mechanism 40, the terminal-burining mechanism 20, and the peeling mechanism 30 for corresponding processing. The first bracket 17 is adjusted to move along the Y direction to adjust the wire-releasing assembly to be close to or away from the cutting mechanism 40, the terminal-burining mechanism 20, and the peeling mechanism 30. The first clamping conveyor belt 12 and the second clamping conveyor belt 13 are adjusted to move to extend or retract the wire, so as to adapt to the different processing requirements of the wire and the requirements for convenient and fast transportation between various processing stations. Specifically, the movement of the first movable mounting seat 11 and the first bracket 17 can be adjusted by means of a pneumatic cylinder or an electric cylinder, and the technicians can select the corresponding model for assembly and use according to actual needs.

[0035] like Figure 4 As shown, an upper movable mounting bracket 31 and a lower movable mounting bracket 32 ​​are arranged correspondingly on the upper and lower sides of the frame 00. The upper movable mounting bracket 31 and the lower movable mounting bracket 32 ​​are both slidably mounted on the frame 00 along the vertical direction. The spacing between the upper movable mounting bracket 31 and the lower movable mounting bracket 32 ​​is adjusted by a spacing adjustment component.
