Automotive wiring harness production process as people safety, economy, comfort requirements gradually increased, and electronic products used in the motor vehicle is also increasing, the failure rate with the use of complicated wiring harness and a corresponding increase. This reliability and durability harness performance requirements becomes higher, many people do not understand harness technology and production, where we have to harness technology and the production of knowledge in this area to do an overview. After drawing out the wire harness production, to arrange the wire harness production process, the production process is the service of the two are inseparable, so we will harness production and process analysis combine the two together.
(A), the first wire harness production line process station is open.
The accuracy of the open line technology directly related to the production schedule, once an error occurs in particular opening line size is short, can lead to rework all of the stations, time-consuming impact on production efficiency. Therefore, the preparation process is the opening line must be reasonable to determine the wire size according to the requirements of the open line drawings, stripping head size.
(B), the second station after the opening line is the crimping process.
According to the terminal type drawings to determine crimp parameters, making the crimping operation manual for special requirements should be specified in the process documentation and training operatives. For example: Some need to lead after passing through the jacket before crimping, it will need to pre-wire and then returns from the pre-crimping station again; there used to pierce crimping crimping tool dedicated this species crimp having a good electrical contact performance.
(III), followed by the pre-process.
First pre-preparation process Operating Instructions, in order to improve the efficiency of the assembly, complex wiring harness must be pre-set station, pre-process is reasonable or not directly affect the efficiency of the final assembly process also reflects the technical level of a person's height. Wire path if too few or pre-assembled part assembled unreasonable workload will increase the general assembly of personnel, slow line speed, so the craft personnel should always stay constantly sum up the scene.
(Iv), the final step is the assembly process.
Can be programmed according to the product development department designed the platen assembly, design tooling equipment, materials, boxes Dimensions and fitting jacket and all annexes number affixed to the material in order to improve the efficiency of the assembly box. The preparation and content of each station assembly requirements, balancing the entire assembly station a little work to prevent excessive pull down the entire line speed situation. To achieve balance station, the process must operate cooked in the heart of every scene and estimated hours of work, at any time to adjust the assembly process.
In addition, the process also includes the preparation of the harness material consumption fixed schedule, work estimates, worker training, and so on, these are not elaborate. Overall harness in the car electronic technology content and quality, has become an important vehicle performance evaluation indicators. For automobile manufacturers harness choice is particularly great importance, it is necessary to understand the process and production under the harness.
