Application

Vision system for notch alignment inspection on wheel housings

The Application

Verifying notch position and alignment in real time

A vision system is essential for checking the manufactured part, ensuring consistent product standards and increasing production efficiency. It enables real-time defect detection and provides data for continuous quality improvement, enhancing reliability and lowering production costs.
For truck wheel housings, the primary application is to measure and verify the angle of the notch, ensuring proper positioning and alignment.

Key Factors

Performance at a Glance

Accurate angle measurement from a long working distance

3000 mm

Camera working distance to the wheel housing.

Angle

Exact notch angle measured and compared with the specified standard.

PLC

Processed data sent to the PLC for further action and control.

Operation

How the inspection works

The system is designed to measure the notch angle accurately so the notch is positioned correctly on the wheel housing.

01

Camera positioned at 3000 mm

The camera is set about 3000 mm from the wheel housing, focusing on the notch.

02

Paddle trigger

When triggered by pressing a paddle, the camera captures the image and processes it.

03

Angle measurement

Image-processing algorithms determine the exact notch angle and compare it with the specified standard.

04

Feedback and PLC

If the angle deviates, the system gives real-time feedback for corrective action, and the data goes to the PLC.

Final Result
