Wire hanging machine for automobile wire harness production
Technical Field
The invention relates to the field of automobile wire harness production, in particular to a wire hanging machine for automobile wire harness production.
Background
In recent years, the global automobile yield is increased year by year, the increase of the automobile yield is benefited by the good economic development situation of the countries of the emerging markets and the market demand caused by the huge population number to a great extent, China still is the biggest single automobile market in the world, and the domestic automobile yield and sales volume are rapidly increased under the benefit of the continuous resurgence of the global economy.
The automobile wire harness is a network main body of an automobile circuit, connects electric and electronic parts of an automobile and enables the electric and electronic parts to play corresponding functions, and the automobile circuit does not exist without the wire harness. At present, the wiring harness, whether it is a luxury car or an economical ordinary car, is basically woven in the same form, and is composed of electric wires, a connector and a wrapping tape, which ensure both the transmission of electric signals and the reliability of the connection circuit. Along with the increase of automobile functions and the common application of electronic control technology, the number of circuits and power consumption on an automobile are remarkably increased, electrical parts are more and more, and wire harnesses are more and longer.
Automobile wire harnesses are often produced in large batches, in a production workshop, a billboard is arranged on each station, workers need to hang different wire harnesses on the billboard according to a certain sequence and a connection mode, multiple wire harnesses to be assembled are placed beside the billboard if being rolled up, a mixed and disorderly workshop environment can be caused, not only the occupied space is interfered with other production processes, unnecessary troubles are brought to workers, knotting or even mutual winding is easily caused between the wire harnesses, the production efficiency is greatly reduced, therefore, a wire hanging frame needs to be placed beside the billboard, the wire harnesses are distinguished according to types, the wire hanging frame is hung on respectively, and the workers can take the wire harnesses conveniently when loading the wire harnesses.
In the existing automobile wire harness production workshop, a wire hanging frame is mostly of a pipe lap joint structure, the longest length of a single wire harness of some automobile types can reach twelve meters, when the wire harnesses required by the automobile types are produced, the wire hanging frame is as high as six to seven meters, when the wire harnesses are placed in the wire hanging frame, at least two persons are required to lift the long wire harness by using two long lifting rods to place the long wire harness on the wire hanging frame, the wire hanging process not only wastes time and labor, but also is easy to cause the danger that the wire harness falls off, and therefore a wire hanging machine is urgently needed, the wire hanging process is safe, convenient and fast, and the requirement of high-speed expansion of automobile capacity is met.
