Robot Harness Design Technology Analysis

At present, with the development of industrial intelligence, China's rise as an industrial giant, mobile robots, at least hundreds of industry applications, with the gradual upgrading of AGV AMR, can adapt to the scene and the environment is also more and more extensive, in this trend, the safety of the robot has become more important, fire prevention, explosion-proof, etc. is directly related to the user's personal and property safety. Wiring harness is the blood vessels and nerves of the robot equipment, the market demand is growing, the quality and process requirements are getting higher and higher, the robot wiring harness is mainly used in the circuit to connect each electrical device inside a wiring component, is composed of terminals, insulation wrapping material, insulation sheath and wire, is the input and output current and signal carrier.

Robot wiring harness in the design process mainly from the risk prevention, risk monitoring and risk blocking, conduction safety and other aspects of the design, as follows: 1. Robot wiring harness design risk prevention: robot wiring harness overcurrent protection mechanism, robot robot controller, motor driver, battery pack and battery management system are a number of high-precision current and temperature sensors, used for real-time detection of current and temperature. In the wiring harness processing design process must be matched between the components to do assessment, as well as the wire can withstand the temperature sensor to do matching, and abnormal current or temperature, to do destructive testing, detection of inaudible body and the robot control system can be reflected in a timely manner, to ensure safety. 2. Robot wiring harness risk detection and risk of interruption of robot controllers, motor drivers, battery packs and battery Management system have a number of high-precision current and temperature sensors for real-time detection of current and temperature. Only cut off the risk of constant monitoring of dual power supply mechanism is safer, the entire robot power supply system will be divided into power power and communication power, power power and communication power are independent and completely isolated. The power portion of the overcurrent is powered separately, and the power board adopts redundant design and derating design, so that the actual overcurrent capacity can reach two times of the rated overcurrent capacity. The mechanism of separating power and communication power can cut off the power power when there is a fault or accident, which also cuts off the energy input of high current on the drive and prevents more serious accidents from happening. At the same time the communication power is normal, the host computer can read the drive status information, real-time monitoring and judgment of faults occurring in the situation. 3. wire selection in both charging speed always ensure that safety is the place, strictly on the large current for the use of derating, such as charging the robot, the design of a larger charging current of up to 50A, but the use of the use of strictly according to the 30A charging (derated to 60%) for the use of the charging. Charging pile with short circuit, overcharge, overvoltage, overdischarge, high temperature and other protection mechanisms. The charging pile has multiple protection mechanisms such as temperature check before charging, prohibiting charging with over-temperature, and actively withdrawing from charging with over-temperature of the vehicle during charging.
