Aoi Mechanical Quality Inspection Machine Vision For Lead Coil Quality Control

Equipment features:

The whole system integrates visual optical hardware (camera, lens, light source, control system),detection system software algorithm, defective product rejection, and counting device. The normal detection speed is 60 pieces per minute. The equipment can achieve 7*24 hours operation. This can greatly improve production efficiency.

The system make a comprehensive detection of side thread problems of the lead ring,With 2 sets of 4K high pixel linear array industrial. cameras.There is a 2 million pixel camera at the top and bottom. After the system collects the sample image, it judges the good and the defective products through the AI deep learning detection system, and detects the defective products online and automatically rejects them.The counting function can be achieved after the finished product is detected, and the counting accuracy rate is 100%.The software will open the sample detection standards, and the production personnel on the customer site can control the defect rate though the accuracy of the comparison and select the accuracy standard most suitable for their own production conditions.

Detection function diagram and principle

Camera location diagram

Basic principles of detection:
 

After the lead coil moving to the designated station, it is held by the clamping mechanism and controlled by a servo motor to rotate for a full circle. At the same time, there is a light source on the side, and the line scan camera captures images at the same time to get a high-resolution scan of the coil side.The detection software compares this image with the standard sample image and detects the corresponding defects.

An area scan camera at the top and bottom of the coil collects and recognizes images from the top and bottom, using artificial intelligence AI algorithms to identify defects and propose defective products.

Detection system function

• Enable and close the system detection function
• Detection index parameters and accuracy adjustment
• Template sampling and storage, sample detection information storage and recall
• Camera image calibration function
• The system displays real-time production information (qualification rate, total output, speed, etc.), browsing, exporting and storing historical production information.
• Permission management based on the login account (such as general operation users can not adjustment parameter ).
• Mechanical operation and adjustment of the system (such as: air valve blow time adjustment, camera trigger time adjustment)
• Additional functions required by Party A
