±0.3mm Accuracy Breakthrough: High-Precision Picking of New Energy Motor Housings

A leading new energy component manufacturer adopted Transfer Technology’s AI+3D vision intelligent loading and unloading system, empowering its motor housing production line with intelligent visual perception. The solution leverages high-precision 3D vision to guide robotic collaborative operation, realizing fully automated, unmanned workpiece handling.

Once activated, the Epic Eye laser 3D camera completes full-scene imaging of the 1200×1200mm tray within 2.8 seconds, accurately identifying tightly stacked motor housings with 6 layers and 4 workpieces per layer. The embedded intelligent algorithm calculates the optimal robotic gripping pose in 1.5 seconds, enabling stable pick-and-place operation with a consistent accuracy of ±1.5 mm throughout the entire process, requiring zero manual intervention.

01Project Challenges

Severe High-Reflection Interference

Motor housings feature smooth metallic surfaces that generate strong specular reflection. Traditional vision systems fail to capture complete and effective point cloud data, resulting in recognition failures and positioning deviations.

Ultra-Tight Stacking Constraints

Each motor housing is only 35mm in thickness, with ultra-close fitting between stacked layers. Dense arrangement leaves minimal operating space for robotic picking, bringing high collision risks during tray clearing and handling.

02Core Technical Solutions

High Anti-Reflection Imaging Capability

Equipped with a self-developed intelligent exposure control algorithm, the Epic Eye laser 3D camera suppresses strong metal reflection interference in real time. It delivers complete, high-quality point cloud data for highly reflective workpieces and lays a solid foundation for accurate pose recognition.

AI Intelligent Trajectory Planning

The deep learning algorithm independently identifies stacked workpiece states and dynamically optimizes robotic moving and gripping paths. It intelligently avoids stacking obstacles and dead zones, achieving an ultra-high tray clearing rate of 99.9% and ensuring smooth continuous picking.

Anti-Vibration Reinforced Structural Design

The camera adopts industrial aluminum profile brackets and chemical bolt fixed installation. The customized shock absorption structure effectively isolates workshop vibration interference, locking visual calibration parameters permanently and maintaining long-term stable positioning accuracy in harsh environments.

03Project Value & Customer Benefits

Significant Efficiency Improvement

The total single-cycle operation time (imaging + algorithm calculation) is optimized to 4.3 seconds. Fully automated unmanned handling replaces repetitive manual work, greatly boosting overall production line throughput and operational efficiency.
