The motor stator slotting machine plays a crucial role in the shaping process of stators and rotors in automotive generators. Its workflow is scientific and efficient. Firstly, it can accurately stack the stator and rotor according to the pre-set angles for each layer in an orderly manner.

During this stacking process, an advanced photoelectric system immediately comes into play, precisely correcting the angles of each layer to ensure the accuracy and stability of the stacking. Once the stacking reaches the target number of layers, a powerful press machine will quickly activate, compressing the stator and rotor to the required thickness, making the entire process seamless. Moreover, the equipment is equipped with intelligent data measurement and recording functions, capable of conducting detailed measurements and records for each finished product, providing strong data support for subsequent quality analysis and process improvement.

In contrast, traditional production methods rely entirely on manual visual correction of the angles of each layer, which greatly depends on the operator's experience and attention to detail, and inevitably leads to significant angle deviations. Due to the limitations of the human eye, it is difficult to ensure the precision of the angles, which may affect product quality. At the same time, the manual correction method is extremely inefficient and can no longer meet the demands of modern industrial production in today's pursuit of high efficiency.

The motor stator slotting machine is equipped with a brand-new FATEK M-series PLC main unit, paired with 8 units of the SC3 series EtherCAT bus-type servo motors and 2 stepper motors. Through advanced motion control methods, it achieves tight coordination of multi-axis motion processes and rapid, precise positioning control. The main unit integrates two 485 ports for machine communication, allowing for the real-time retrieval of camera inspection results and stepper motor angle correction. Additionally, the integrated measurement channels can instantly obtain press force, ensuring the press force is within the required range.

The machine's workflow includes steps such as material loading, stator or rotor grasping, visual inspection and positioning, angle correction (with repeated photography and comparison until the angle is OK), visual re-inspection, stacking (with 6 layers of rotors and 7 layers of stators forming a complete product, with angle deviation within 0.05 degrees), press molding, data measurement and recording, and finished product output. The stator and rotor stations work independently without affecting each other, and each layer's material grasping and correction must be completed within 30 seconds.

This equipment has many advantages, with high-precision control achieved through advanced motion control methods and visual inspection systems, ensuring product quality. Efficient production is due to a reasonable workflow and fast operation times, meeting the needs of large-scale production. Real-time measurement and recording of finished product data provide strong support for product quality analysis and process improvement, enhancing corporate management standards. The independence of the stator and rotor stations allows for simultaneous production, increasing equipment utilization rates.
