Design methodologies and maintenance strategies of air conditioning outdoor unit assembly production line for intelligent manufacturing

With the continuous improvement of contemporary demands for air conditioning quality, the upgrade of air conditioning production lines is imperative. The assembly of central air conditioning outdoor units is a key link in the intelligent upgrade of the air conditioning manufacturing industry, and its level of automation and intelligence directly affects product quality and production efficiency. However, traditional production lines suffer from low levels of automation, insufficient positioning accuracy, and delayed material replenishment, which restrict the high-quality development of the industry. Therefore, based on the cyber-physical system architecture, this study systematically constructs an integrated solution for an intelligent production line. Specifically, an overall production line architecture incorporating high-precision positioning devices and flexible execution units is designed, and a flexible fixture featuring a composite positioning system and an adaptive pneumatic system is proposed, thereby achieving precise positioning and reliable clamping of workpieces during transmission and assembly. Furthermore, a real-time material replenishment system integrating automated guided vehicles, machine vision, and 5G communication is developed, enabling rapid response and accurate replenishment for material shortages through dynamic perception and intelligent scheduling. Through data comparison, this solution has increased the overall efficiency of the production line by 57%.
