What are the structured process requirements for wire harness assembly kits?

The process database is the foundation of the automotive wiring harness assembly system, which not only stores the structural and process information of each wiring harness product, but also provides basic data such as raw material information, process methods and process parameters for the system to describe the product information and process decisions. For the withstand voltage test, when adding high voltage to a circuit, the system terminates the circuit and does grounding. Each circuit is tested one by one, and if there is only one circuit in the test system, the system ground is automatically tested for high voltage. Withstand voltage test has a normal test and fast test two ways, normal test for the circuit of the distributed capacitance and capacitive devices is relatively large cable tester is to complete the system integrated wiring test platform, to truly realize the complex wiring harness assembly system integrated wiring test, but also need to be added to the test interface adapter, complete the tester interface with the device under test interface. The software runs in the environment of real-time multi-tasking operating system, making full use of the real-time multi-tasking management, inter-task communication and synchronization services, interrupt management and other functions provided to a group of closely matched processes, running concurrently in the same system. The load-bearing system consists of a load-bearing platform and a follower fixture. The follower fixture of the automotive electric appliance is mounted on the soon-to-be-designed load-bearing platform, and is excited on an excitation table connected to the load-bearing platform. The vibration table is used by the Lupu signal as an excitation source to simulate the vibration condition of the vehicle under different road conditions and exercise states, thus providing a test environment for the electrical system clamped on the load-bearing platform, and the whole inspection system framework. From the point of view of providing an experimental environment for the test considerations, the requirements of the entire test bearing platform and its matching with the shape of the fixture as much as possible to simulate the experimental electrical installation in the car in the armchair state, which in the process of assembly of the wiring harness on the bearing platform geometric dimensions requirements. The outer diameter of the harness depends mainly on two factors: the plastic extrusion flow rate and the main traction speed of the system. When the system is running steadily, the main haul-off speed reaches the set value, the outer diameter depends only on the extrusion flow rate of plastic, the flow rate increases, the outer diameter increases, and vice versa, the outer diameter decreases. When the system is running at variable speed, the rotational speed of the extruder screw is adjusted to change the plastic flow rate to maintain the wire diameter. When the extrusion flow rate is constant, the traction speed increases and the outer diameter of the wire harness assembly product decreases; conversely, the outer diameter increases. The extrusion flow rate of the plastic is determined by both the screw speed and the structure of the extrusion equipment. The extrusion equipment is similar to a heating furnace device, which can be equated to a first-order inertia plus a pure hysteresis link, the screw speed control system is a DC closed-loop speed control, and the model can be equated to a second-order inertia link.
