Application: Method for manufacturing stator for rotary electric machine (Patent ID: US20240030788A1)
The patent filed by Aisin Corp. describes a method for manufacturing a stator for a rotary electric machine, involving the installation of coil pieces in a stator core and joining the ends of the coil pieces or the coil piece end and a busbar using laser welding. The joining process includes steps such as bringing the ends into contact, detecting image features related to non-contact surfaces, and determining the laser radiation position based on these features.
Furthermore, the method includes utilizing image recognition to detect features related to non-contact surfaces, positioning the ends with a jig during the setting step, and capturing images with a camera aligned along the non-contact surfaces. By linearly changing the laser radiation position based on the detected features, the method ensures precise and efficient laser welding of the stator components. Overall, this innovative manufacturing process enhances the quality and accuracy of stator production for rotary electric machines.
