Description

Assembly method of automotive wiring harness {Method of assemble and test for automotive wiring harness}

The present invention relates to a method for assembling and inspecting an automotive wiring harness.

In general, the electric device of the car can be likened to the nervous system, and the car can exhibit the original excellent performance only when the electric device is normally operated. The electric device of the car can be divided into the electric device of the engine related to the operation of the engine and the body electric equipment installed in each part of the car body other than the engine. Today, the electric parts of the car are the development of general electric equipment and the expansion, safety, As the improvement of the habitability and convenience is required, the range of electric devices is expanding.

In general, other circuits except for the high voltage circuit and the starting circuit among the electric circuits of the vehicle are very many circuits, and the wiring harness is made by assembling the wiring harness in a form that can be smoothly assembled in the assembly line of the vehicle. As the electric wires, low-voltage wires for automobiles, thin low-voltage wires for automobiles, and the like are used, and heat-resistant low-voltage wires for automobiles are also used to cope with high temperatures in the engine room. In addition, in recent years, the use of noise preventing twisted wires and insulated shielded wires has been increased in response to electronics for automobiles. As terminals, various terminals and connectors are used in addition to standard products of automotive wire terminals and automotive multipole connectors. Vinyl tape is generally used for focusing a bundle of electric wires. In addition, vinyl tape tubes, corgate tubes, glass fiber tissue tubes, resin forming protectors, and the like are used for mechanical protection of wiring harnesses. In addition, as the wiring harness becomes more complicated and the number of circuits increases, it is necessary to pursue a circuit that is optimal for the vehicle structure, and a wire that satisfies all requirements such as safety, assembly, serviceability, standardization, and publicization of the circuit. The ring harness system is important.

Figure 1 shows a flow chart of the manufacturing procedure of the automotive wiring harness. The wiring harness manufacturer receives the drawings from the vehicle manufacturer, prepares the manufacturing plan and bill of materials (BOM) for manufacturing, cuts the wires to the required length (12), and cuts the terminals into the autoclave. By pressing 13, the intermediate sub assembly 14 to focus the sub assembly (sub assembly), the intermediate sub assembly (sub assembly) arranged in a predetermined form and finished products to focus on the vinyl tape or the like After the assembly step 15, after the step of performing a circuit test in a separate circuit inspection jig (16), and finally performing a visual inspection and finishing (17) step (18) Will go through.

However, in the conventional technology, the production design and assembly stage of the product is performed by the function and manual work of the production worker, and the input of each part number is performed in lot units, resulting in a long production process time and a process input of other part numbers. There is a disadvantage in that loss of time and education is caused by replacing the assembly process at the time of the assembly process. Since the circuit inspection step has only the function of circuit inspection, it does not contribute to the improvement of productivity during assembly work, and the circuit inspection is performed in the finished product state. Therefore, in case of a circuit defect, there are disadvantages such as disassembling and modifying the product again.

SUMMARY OF THE INVENTION An object of the present invention is to install and inspect a wiring harness for a vehicle in order to solve the above problems, setting hardware in an assembly and inspection computer, loading working data, and whether the hardware is operating normally. Test the assembly, conduct the wire assembly and conduction inspection, and indicate the position where the wire is loaded by the identification LED at the wire loading stand in the production process, and the position of the connector to be assembled by the connector insertion instruction LED on the assembly plate. And the wire insertion instruction LED to indicate the position of the connector pole to which the wire is to be inserted, thereby providing the operator with information on the assembly position when assembling the wiring harness to improve work efficiency, The production process time is shortened due to no lot unit input and no other part number is added. Also it is possible to prevent the loss of such time and training by replacement of the assembly process, and to at the same time precise circuit assembly comprising improve product quality by the assembly provides a way to carry out the functions of the circuit test.
