Raw material function and process production of wire harness products

The requirements for the wires in the automotive wiring harness are very strict and different. Starting from its electrical performance, temperature resistance and material divergence, for example, the engine harness wire must be high temperature, oil resistance, shock resistance and good wear resistance; the automatic transmission wire should be high temperature resistance, hydraulic oil resistance and stable performance; the harness on the box cover must be selected to maintain its inherent elasticity in low temperature environment, and the cold elastic wire should be selected to ensure its normal operation; ABS wiring harness requires high temperature conditions, usually the temperature is between 150-200 ℃, the insulation is hard, the wear resistance is good, but more than 133 stranded conductors should be selected. The functions of vehicle wiring harness products can be divided into two categories, one is the wire that drives the power of the actuator, and the other is the signal line that transmits the input command of the sensor. The thick wire that can carry large current is the power line, and the thin wire that does not carry power is the signal line. With the change of social demand and the rapid development of science and technology, the functions of automotive modules are increasing, and electronic technology has been widely used in modern new automobiles. Electronic control system is closely related to automotive wiring harness. The function of the harness is similar to that of blood vessels in the human body, and it is a necessary component. Automobile ECU and other control modules are similar to the brain of the automobile. The various types of receptors and sensory nerves on the automobile are the same, while the actuators are the same as the motor organs, namely nerves and blood vessels. With the combination of science and technology and the multi-function of automobile, there are many contradictions and problems, such as: how to arrange the vehicle wiring harness effectively and reasonably in the limited body space, so that it can play the greatest role and function. The production process of automotive wiring harness can be divided into four processes: First, the wire opening and crimping process. The process of line opening needs to be careful and rigorous, and its accuracy affects the whole production schedule, and any error will affect the production efficiency. Therefore, at present, the vast majority of wiring harness manufacturers use fully automated wiring equipment. Crimping process requirements: Crimping parameters and required crimping dies shall be determined according to the crimping standards and terminal types of customers. Because the crimping quality is directly related to the electrical performance, this station is a key station, and it is necessary to have a crimping operation instruction describing the requirements of special characteristics, and to form a control chart by sampling the crimping quality online according to the proportion. The second is the pre-assembly process. The pre-binding process shall be carried out according to the procedure. The main work is to feed the wires that have been opened and crimped and process the plastic parts into KIT according to the process instructions, which helps to reduce the investment cost of the general assembly line equipment, reduce the difficulty of the general assembly operation and reduce the number of general assembly operators. For the simple car harness, the pre-installation can be cancelled directly, while for the complex car harness, the pre-installation station should be set first. Third, the final assembly process. Arrange the pre-assembled harnesses on the assembly board in an orderly manner according to the process instructions, and arrange them according to the process instructions, such as winding, bundling, installation of rubber parts, etc. Fourth, it is the post-assembly process. Including installation of support, live detection, full size inspection and wrapping and packaging.
