After the automation transformation of the humanoid robot joint motor production line, the per capita output efficiency of a single production line has increased by 60% -90%, the core precision process utilization rate has reached over 92%, and the overall machine defect rate can be reduced to less than 1.2%. 1, Quantitative performance of efficiency improvement
Per capita output improvement: Before the renovation, the per capita assembly of joint motors in a single manual shift (8 hours) was about 120 units. After the renovation, the per capita assembly of joint motors in a single shift reached 210-228 units, with a corresponding increase of 60% -90%; If it is a fully manual new production line before the renovation, the improvement rate will be narrowed to 45% -60%
Process utilization rate improvement: The utilization rate of manual workstations for core processes (precision winding, stator slot embedding, magnetic steel patching) is about 65% -70%. After the transformation, the utilization rate of flexible automation special machine workstations has been increased to over 92%, and the utilization rate of continuous operation of the entire line has reached 85%
Optimization of defect rate control: The defect rate of manually assembled joint motors is about 3.5% -5%. After transformation, through automated processes such as visual positioning and torque locking, the defect rate has been reduced to less than 1.2%. Among them, the defect rate of precision winding has been reduced from 2.1% to 0.3%. Secondly, key conditions affecting the improvement effect: (1) The original foundation of the production line needs to be a semi-automatic production line with basic processing capabilities. If it is a fully manual new production line, the efficiency improvement can be about 45% -60%, which is lower than that of mature transformation production lines. (2) Equipment flexible adaptation: Flexible automation equipment that supports 5-8 mainstream joint motor models needs to be used. When a rigid special machine is adapted to a single model, the proportion of product switching and stopping is 15%, which lowers the overall efficiency by about 12%. (3) Configuration of operation and maintenance personnel: Two production line operation and maintenance personnel are required to be responsible for equipment debugging and troubleshooting, If only the original front-line operation post configuration is retained, the downtime due to equipment failure will increase by 30%, and the actual improvement rate will decrease by 10% -15%
