Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness production equipment, and in particular relates to a material feeding mechanism for sample wires or sleeves of vehicle wire harnesses. Background Art

[0002] In the process of making sample wires of vehicle wiring harnesses, it is necessary to cut the cables and casings of various sample wires first, that is, to pre-cut the cables or casings of the required length. The cables and casings required for the sample wires generally have a wide variety and different lengths, but the required quantity is relatively small. Therefore, if an automatic cutting machine is used, it will not only be costly, but also require frequent replacement of cable loops or casing loops and adjustment of the cut length procedure, so the efficiency is extremely low; if the length of the cable or casing is measured manually and then cut, it will also lead to low efficiency, and it is easy to cause problems such as confusion of cables or casings, inaccurate control of cable or casing length, and uneven cuts.

[0003] In the prior art, a patent document with announcement number CN 210490050 U discloses a feeding mechanism of a wire harness crimping machine, including a crimping machine body and a feeding device, the feeding device including a rectangular feeding table, the crimping machine body is fixedly installed on one side of the feeding table, a wire shifting device is fixedly installed on the side of the feeding table away from the crimping machine body, a wire straightening device is fixedly installed on one side of the feeding table, the wire shifting device includes a wire shifting rod and an electric push rod, the axis of the electric push rod is perpendicular to the second side, the wire shifting rod is located on the upper side of the feeding table, a clamping claw for clamping the wire harness is fixedly installed on one end of the wire shifting rod close to the crimping machine body, the wire straightening device includes a conveyor belt, and the transmission direction of the conveyor belt is toward the side away from the feeding table, the upper surface of the conveyor belt is not higher than the upper surface of the feeding table, and a wire take-up platform is installed on the lower side of the wire shifting device, and the height of the wire take-up platform is lower than the upper surface of the feeding strip. Although the above solution avoids the phenomenon of chaotic wiring harness, it is not suitable for sample line production, and cannot avoid problems such as frequent replacement of cable loops or sleeve loops and adjustment of the cut length leading to reduced efficiency.
