Sizector® 3D Camera SX Series
新能源汽车电机对车辆的动力、舒适性、经济性和安全性都起着极为重要的作用，是三电系统的绝对核心组成部分。相比传统电机，扁线电机提升了内部空间利用率和散热性能，实现了更高的功率密度，同时能承受更高的工作温度，因此备受新能源汽车厂商青睐。本期我们来看盛相科技Sizector®3D相机SX系列在扁线电机焊点检测中的应用。
New energy vehicle motors play an extremely important role in the power, comfort, economy, and safety of vehicles. Compared to traditional motors, hair-pin motors improve internal space utilization and heat dissipation performance, achieving higher power density while being able to withstand higher operating temperatures. Therefore, they are highly favored by manufacturers of new energy vehicles. In this issue, we'll explore the application of Mega Phase Technology's Sizector® 3D Camera SX series in the inspection of welding points in hair-pin motors.
焊点数量多High Number of Weld Points
以六层的扁线电机为例，48个槽，平均每个槽3个焊点，共计144个焊点
Taking a six-layer Hair-pin motor as an example, with 48 slots and an average of 3 welding points per slot, totaling 144 welding points.
成像难Challenges in Imaging
焊点属于金属高反弧面，拍摄外围焊点容易产生畸变，边缘成像效果差，质量问题判定困难
Welding points are situated on high-reflectivity metal surfaces, resulting in distortion when capturing outer weld points, leading to poor edge imaging and difficulties in quality assessment.
检测项目多Multiple Inspection Tasks
焊点位置度、轮廓度及各类焊接瑕疵检测
Inspection tasks include positional accuracy, contour measurement, and inspection of various welding defects for each weld point.
Sizector®3D相机SX系列采用硬件计算成像、多投影技术和远心镜头，面阵成像，同时检测多个焊点，特别适合扁线电机焊点质量检测。
The Sizector® 3D camera SX series employs hardware computation imaging technology, multi-projection technology, and telecentric lenses. It utilizes area-array imaging and can simultaneously inspect multiple welding points, making it particularly suitable for quality inspection of welding points in Hair-pin motors.
