How to Solve Random Positioning Challenges for Automotive Suspension Pin Holes? Transfer Tech delivers an Efficient Solution

Currently, industrial automation is flourishing, and 3D vision guidance technology is shining brightly in the automotive manufacturing field, increasingly demonstrating its critical influence.

Project Challenges

Frequent mannual handling and loading result in high labor intensity, and production efficiency cannot meet production demands. Pin holes are randomly placed in deep bins, making precise picking impossible. Pin hole workpieces feature reflective surfaces, making stable point cloud data generation difficult and posing high recognition challenges.

Workflow

In this customer project, the AI+3D vision guidance system performs positioning for automotive suspension pin holes and guides the robot to pick workpieces from material bins and place them at the loading station. The detailed workflow is specified as follows:

Workpieces are delivered to the assembly station via the conveyor line. Transfer Technology’s Epic Eye Laser L 3D camera, mounted on the sixth axis end of the robotic arm, captures scans of specific positions on workpieces and placement fixtures for visual recognition.

Station 1 (Front Suspension): The system performs visual positioning on workpiece suspension pin holes. The fixture inserts locating pins into the pin holes, and the robotic arm transports the workpiece above the placement fixture. After positioning the placement fixture via the Epic Eye Laser L camera, the system guides the robotic arm to accurately place the workpiece on the fixture.

Station 2 (Rear Suspension): The system conducts visual positioning on workpiece features. The fixture supports and moves the brake disc component. The robotic arm carries the workpiece to the upper side of the placement fixture. With the 3D camera completing fixture positioning, the system guides the robotic arm to place the workpiece in place.

Customer Value

The adoption of Transfer Technology’s AI+3D vision guidance technology delivers remarkable value for customers. It effectively improves production efficiency and product quality while boosting overall operational stability. Furthermore, this technology reduces labor intensity, cuts labor costs, and lowers reliance on manual operation.

Technological innovation strengthens enterprises’ brand influence and market competitiveness. It enables rapid adaptation to vehicle model changeovers without extensive hardware upgrades, realizing highly flexible manufacturing. The system also delivers outstanding performance in both precision and efficiency. It maintains a positioning accuracy within ±0.5 mm for front suspension components and ±1 mm for rear suspension components, ensuring high-precision assembly. The entire vision process is completed within 12 seconds per cycle, sustaining high-speed production.

Against the backdrop of the automotive manufacturing industry, the continuous iteration and in-depth application of AI+3D vision technology is driving profound industrial transformation. Traditional operational modes are being gradually replaced, paving the way for a new paradigm of intelligent manufacturing.
