The production efficiency improvement of the automation transformation of the cold shrink terminal production line can reach 30% -70% in mainstream transformation. The higher the standardization level and automation coverage of the production line specifications, the greater the improvement, with an upper limit of nearly 80%
1, The core range for efficiency improvement
Regarding the existing domestic cold shrink terminal production lines (covering mainstream specifications of 10kV and 35kV), they are divided into three categories according to the depth of renovation:
Core workstation (crimping, pipe expansion) renovation: increased by 30% -40%, only replacing manual repetitive operations;
Semi automated (including feeding and offline detection) transformation: increased by 45% -60%, covering key links with manual assistance;
Full process automation (including online detection and palletizing) transformation: Improve by 60% -80%, achieving unmanned operation of the entire process from materials to finished products. 2, Key variables affecting the extent of improvement
(1) Product specification concentration: For production lines with a single specification order proportion of ≥ 70%, the automation cycle can be stably matched, and the improvement rate is 15% -20% higher than that of multi specification mixed line production lines; (2) The proportion of manual bottleneck workstations: In the original production line, manual operations account for ≥ 60%, and this workstation has high repetition and high errors (such as manual pipe expansion size deviation ≥ 5%). After transformation, the improvement can reach 55% -70%; If manual assistance is only used, the improvement rate is only 20% -35%; (3) Equipment compatibility: Automation equipment that is compatible with existing fixtures and jigs does not require additional adjustments to the production line layout, resulting in no loss in improvement; If a significant adjustment of the tooling is required, it will lower the actual efficiency by 5% -10%. 3, The actual implementation boundary of efficiency improvement
Order structure limitations: If the production line is mostly small batch, multi specification customized orders, and the fully automated transformation takes too long to change molds, the actual improvement rate is only 30% -45%. It is recommended to prioritize semi automated transformation;
Personnel skill matching: Personnel who have not received specialized training operating automation equipment may experience downtime and wait due to misoperation, resulting in a 10% -15% decrease in improvement.
