3. Intelligent application of laser welding vision for hairpin stator

Visual capture efficiency and stability beofre laser welding

Visual System:
•   Equipped with 6 million pixel high-resolution industrial camera, coaxial installation, can eliminate errors caused by tilted installation, the accuracy can reach 0.02mm;
•   Can be matched with different brands, different resolution cameras, different galvanometer systems and different light sources, with a high degree of flexibility;
•   The software directly calls the laser control program API, reducing the time to communicate with the laser and improving system efficiency;
•   Pin clamping gap and angle deviation can be monitored, and the corresponding welding procedure can be automatically called for the deviation pin;
•   The pins with excessive deviation can be skipped, and repair welding can be carried out after the final adjustment.

Intelligent trajectory of laser vision

•   With a variety of visual tools, flexible solutions, easy to customize, you can grab points, lines, circles, ellipses and their complex graphics;                                           
•   For pins with a slightly larger fit gap, you can visually skip the gap, and then continue welding after the gap is fused.

4. Difficulties and solutions for laser welding of hairpin stator
