In recent years, many motor production enterprises have also taken precautions and begun to focus on the intelligent automation of motor production. However, due to the messiness and particularity of the motor production process, in the specific process of motor production, in order to ensure the accuracy of the parts, it is still necessary to rely on the traditional manual operation, such as the rotor shaft, rotor die-casting and other processes, but these processes require workers to wear protective equipment to operate at high temperatures, which not only has a large risk factor, but also has low working power and high labor intensity. Therefore, with the deepening of intelligent manufacturing, the demand for how to increase the production power and reduce the labor cost of motor production is becoming increasingly significant.
Siemens CNC (Nanjing) Co., Ltd. (SNC) was established in 1996, the company's main product line covers CNC systems, general inverters and servo motors; Siemens Motor (China) Co., Ltd. was established in 2006 and has reached a production capacity of 1 million three-phase asynchronous motors and 200,000 servo motors per year.
With the continuous growth of the company, the traditional production methods can no longer meet the needs of motor production, so the two companies are actively seeking to improve the production line power through robots with an innovative attitude.
KUKA robot is sensitive, easy to operate, and easy to program, which greatly reduces the difficulty of employees to use the motor and the cost of the company's training employees; In addition, KUKA robots can meet the high requirements for stability, accuracy and cycle time of motor production due to their high positioning accuracy, low failure rate, and support for third-party development. Therefore, Siemens decided to choose KUKA as the partner of intelligent automation, and began to combine the various processes of motor production to improve the automation solution for the motor industry step by step, and liberate workers from the operation with high risk factor and high labor intensity while improving power and ensuring product quality!
Excellent quality, adapt to messy working conditions
In the production of motors, the rotor shaft insertion process adopts the hot sleeve process, which has higher requirements for temperature, accuracy and beat, and the operator is required to wear protective equipment and manually insert the shaft after the core is heated. In the face of such a messy working conditions, Siemens selected KUKA as a partner, thanks to KUKA accumulated rich experience in different industries, when talking about the impact of the use of KUKA robots on the rotor insertion process, Mr. Li Bao, an engineer of the manufacturing engineering department of Siemens CNC (Nanjing) Co., Ltd., said: "After the use of KUKA robots, the production cycle time has been shortened to 50% of the original while reducing the labor intensity and safety risks. ”
Simplify the complex, and liberate manpower with science and technology
The servo motor shaft processing unit is used for producing the motor shaft, the station has a total of 5 processes, the equipment operation and the circulation between the processes are carried out manually, the operation is complicated and the circulation time of the process is longer, and the equipment utilization rate is not high. After using KUKA robots, Mr. Yao Guojun, the person in charge of the servo motor shaft machining project of Siemens Motor (China) Co., Ltd., was deeply touched by the outstanding performance of KUKA and said: "After using KUKA robots, the flow between processes is smooth. ”
Precision is sensitive, and power quality is parallel
After the use of KUKA robots in the motor active packaging line, the OEE and production quality of the equipment have been improved, and the production cycle time has been shortened to 40% of the original time, which has greatly improved the production power and ensured the consistency of the product.
