Spark Plug Inspection System
Automated Spark Plug Inspection System enables End of Line Quality Control of Automobile or Aircraft Spark plugs.
The Spark Plug Inspection system seamlessly integrates into the production line. The inspection begins with the operator loading the spark plugs onto the conveyor. As each plug advances, our comprehensive dual-camera inspection station captures images from both top and side views. This dual-camera approach, utilizing a 4MP area scan camera (for the top view) and a 2MP camera (for the side view), ensures complete coverage for detailed analysis.
The system requires an approximate 75-millisecond window. This brief static period allows the cameras to capture clear, undistorted images. These images are then processed using custom image processing algorithms, specially designed to discern between acceptable (OK) and defective (Not OK) parts. Any identified defects trigger the system to redirect the flawed spark plug to a designated rejection bin. Meanwhile, the accepted parts seamlessly proceed to the end of the line, accumulating in a designated good bin.
