In modern motor manufacturing, the stator is an important part of the motor, and its processing quality directly affects the performance and life of the motor. In order to improve production efficiency and ensure the manufacturing accuracy of the stator, the stator automatic line has become an important equipment for motor production. The stator automatic line can realize a series of automated production processes such as stator coil winding, insulation treatment, wire embedding, shaping, binding, varnishing, and drying, greatly improving production efficiency and product quality. This article will introduce the working principle of the stator automatic line and analyze its core components.
The main task of the stator automatic line is to wind and install copper wire or aluminum wire into the stator core according to the set process requirements, and complete subsequent processing to make it have electromagnetic characteristics and drive the rotor to rotate. Its basic work flow is as follows:
Core preparation and insulation treatment
The stator core enters the production line through an automatic conveying system, and puts insulating paper or applies an insulating layer in the slot to prevent the coil from short-circuiting.
Use an automatic winding machine to wind copper wire or aluminum wire into a coil that meets the motor requirements according to the set parameters, and ensure that the winding is uniform and tight.
Use an automatic wire embedding machine to accurately embed the wound coil into the slot of the stator core. This process must ensure that the coil does not damage the insulation layer, while ensuring the filling rate and position are accurate.
After the coil is embedded, it needs to be shaped to arrange the coil neatly to avoid failures caused by poor contact or looseness during operation.
Use a binding machine to fix the winding to improve structural stability.
Use an automatic welding machine to connect the winding ends, and connect the stator coil lead-out end to the terminal to ensure reliable electrical connection.
In order to enhance the insulation performance and durability of the winding, the stator needs to be dipped in paint (generally using vacuum pressure dipping) to allow the insulating paint to evenly penetrate the coil and improve the high temperature resistance and vibration resistance of the motor.
After that, the stator will enter the drying equipment to solidify the insulating paint and enhance the mechanical strength of the stator.
The insulation performance, voltage resistance, inter-turn short circuit, DC resistance and other parameters of the stator are checked by automatic inspection equipment to ensure that the product quality meets the standards.
The stator automatic line consists of multiple key equipment, each of which undertakes different tasks in the production process to ensure the automation, precision and efficiency of the entire process.
Responsible for winding copper wire or aluminum wire into coils, controlling the number of turns, tension, wiring accuracy and other parameters of the winding.
It is used to adjust the shape of the coil after embedding so that it is arranged neatly, reduce the gap between the coils, and improve the tightness.
The coil is fixed on the core using high-speed binding technology to prevent loosening or deformation during operation.
Weld the winding ends to make the wires firmly connected and ensure the normal operation of the motor.
Use vacuum dipping or spraying to make the insulating paint evenly cover the coils and improve the insulation performance. The drying equipment is used to accelerate curing and enhance mechanical strength.
Including voltage resistance test, inter-turn short circuit detection, DC resistance measurement, etc., to ensure that the various parameters of the stator meet the standards and improve the product qualification rate.
Improve production efficiency: fully automated operation, reduce manual intervention, and greatly shorten production time.
Ensure product quality: high-precision equipment ensures the stability of winding, embedding, welding and other processes, and improves consistency.
The application of stator automatic line makes the motor manufacturing process more efficient and accurate, and greatly improves product quality. In industries such as industrial automation, home appliances, automobiles, and new energy, stator automatic lines have become indispensable production equipment. With the development of intelligent manufacturing, stator automatic lines are also constantly upgrading, and will develop towards higher precision, greater flexibility, and greater intelligence in the future, bringing more innovations and breakthroughs to the motor manufacturing industry.
