Wire harness test production line

Abstract

The invention relates to a device for processing an electric appliance wire harness, in particular to a wire harness test production device. According to a wire harness test production line, in a horizontal test platform (1), two horizontally rotating chain wheels (8) are arranged in the length direction, wherein one chain wheel is a driving chain wheel, and the other chain wheel is a driven chain wheel; a chain (9) encircles the two chain wheels (8) to form a circle of conveying chain; a plurality of hooks (3) are outwards extended on the chain (9), every two hooks (3) are connected with a test plate (7), a plurality of groups of wire harness sockets (4) are arranged on the test plate (7), and each group of wire harness sockets (4) is electrically connected with a wire harness tester (6) respectively; and the test plate (7) is arranged on an oblique bracket (10), and the lower part of the oblique bracket (10) is provided with a roller (11). The wire harness test production line relieves the labor intensity, has simple and labor-saving action, is not easy to cause accidents and errors, greatly improves the test speed, has accurate and reliable test result, and improves the turnover efficiency and the speed of the whole work.

Description

technical field [0001] The invention relates to a kind of equipment for the processing and production of electric wire harnesses, and the specific requirement is related to a kind of wire harness testing and production equipment. Background technique [0002] The wiring harness is the wiring part that connects various electrical equipment in the circuit, and is composed of insulating sheaths, terminal blocks, wires and insulating wrapping materials. [0003] Automobile wiring harness, in order to facilitate installation and maintenance and ensure that electrical equipment can work under the harshest conditions, the wires of different specifications and colors used in the electrical equipment of the whole vehicle are integrated into one body through reasonable arrangements and insulated The material bundles the wires into bundles for integrity and reliability. [0004] The electrical equipment on the car selects the cross-sectional area of ​​the wires used according to the s...

AI Technical Summary

Problems solved by technology

[0009] 1) Natural damage: The use of the wire harness exceeds the service life, aging the wires, cracking the insulation layer, and significantly reducing the mechanical strength, causing short circuits, open circuits, grounding, etc. between the wires, causing the wire bundles to burn out

Oxidation and deformation of wire harness terminals, resulting in poor contact, etc., will cause electrical equipment to malfunction

2) The damage of the wire harness due to the failure of the electrical equipment: When the electrical equipment is overloaded, short-circuited, grounded, etc., the wire harness may be damaged

3) Man-made failure: when assembling or overhauling auto parts, the metal object crushes the wire bundle, causing the insulation layer of the wire bundle to break; the position of the wire bundle is improper; the lead wire position of the electrical equipment is wrongly connected; When the circuit fails, random connection, random cutting of wire bundles, etc., can cause abnormal operation of electrical equipment, and even burn out the wire bundle.

[0012] The market demand for wire harness products is large, the production volume of the enterprise is large, the production rhythm is fast, and the production efficiency is high. However, the existing test method, single detection seriously restricts the production speed and efficiency. The reason for the slow test speed is mainly In the assembly and disassembly procedures of wire harness products, an operator inserts and installs each connector of a wire harness, and then hands it over to the inspector in the next process for conductivity detection, and then unplugs it after the inspection is completed, so the cycle operation

At present, the wire harness tester is an electronic product. Relying on the existing computer technology, it is completely possible to configure a multi-line test instrument with strong testing ability and fast speed. Even if multiple wire harnesses are tested at the same time, it can instantly and accurately judge whether the wire harness is qualified or not. No, and which strand of the wire harness is faulty, therefore, the assembly and circulation methods of the test device in the prior art limit the improvement of test work efficiency
