In recent years, automated smart production has developed rapidly, and the functions of robots have become more advanced and more humane. Many factories have implemented automated production, and injection molding machines are generally equipped with robots, which greatly improves the productivity of the injection molding machine, product quality and ensures safe production. However, during long-term operation, the injection molding manipulator is affected by a variety of factors, and problems and failures of varying degrees will inevitably occur. Therefore, regular maintenance is crucial.
Routine maintenance of equipment is the basis of maintenance at all levels and is directly related to operational safety, energy consumption, and service life of machine parts. Routine maintenance operations are carried out by the equipment operator. The main contents of the operation center are cleaning, supply, safety and inspection. The three inspection systems are adhered to before starting work, during operation and after completion of work. Check the reliability of the control mechanism, operating parts, and safety protection devices, maintain the cleanliness of the entire machine and each assembly, lubricate must be in place, and tighten loose parts, etc. In order to use the manipulator normally for a long time and prevent the occurrence of mechanical failure, regular inspection of the manipulator must be carried out.
