Sizector® 3D Camera SX Series
For electric vehicles, or EVs, motors are key to building a powerful, comfortable, economical, and safe final product. Compared to traditional motors, hairpin motors make better use of internal space and dissipate heat more efficiently. Consequently, they achieve higher power density and withstand higher operating temperatures. No wonder they are highly favored by manufacturers and take the center stage nowadays. However, the dense and shiny metal hairpins always confuse the vision system and output incorrectly, resulting in waste or low quality. But with the Sizector 3D Camera SX Series, inspecting a hairpin motor becomes much easier and more stable. Let's explore how it works together.
High Number of Weld Points
Taking a six-layer Hairpin motor as an example, with 48 slots and an average of 3 welding points per slot, totaling 144 welding points.
Challenges in Imaging
Welding points are situated on high-reflective metal surfaces, resulting in distortion when capturing outer weld points, leading to poor edge imaging and difficulties in quality assessment.
Multiple Inspection Tasks
Inspection tasks include location, profile tolerance measurement, and inspection of various welding defects for each weld point.
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 hairpin motors.

The Sizector® 3D camera SX series employs telecentric lenses to minimize edge distortion during snapshots, ensuring complete imaging of each welding point within the field of view. It can seamlessly integrate with external lighting to synchronize exposure control. This setup simultaneously outputs both 2D grayscale images and 3D point cloud data, providing a one-stop, comprehensive solution for both 2D positional accuracy and 3D defect inspection.
The Sizector® 3D camera SX series inherits Mega Phase's unique camera hardware HDR fusion technology, providing better imaging integrity for highly reflective materials and ensuring more stable and accurate 3D data. This ultimately helps users improve the accuracy of welding point quality inspection.
