Atonm 900E Solves the Challenge of Stack Detection for Hollow Metal Rings

I. Customer's Dilemma: Detection Challenges Arising from Special Structures

An auto parts manufacturer encountered detection difficulties during the processing of wheel hub metal rings: the formed metal rings are hollow, with the central hollow area accounting for 60% of the total area. Traditional double-sheet detectors rely on signal acquisition in the central area, which tends to cause misjudgments during edge detection. The production adopts conveyor belt transportation (with a speed of 1m/s), requiring the detection equipment to accurately identify double sheets at the edges without affecting the efficiency of the assembly line. Previously, the defective product rate caused by double-sheet stacking reached 8%, and the monthly mold maintenance cost exceeded 50,000 yuan.

II. Atonm's Solution: Special Optimization for Edge Detection

Based on the on-site working conditions, Atonm's technical team recommended the 900E Metal Double Sheet Detector, improving detection reliability through three core technologies:

Edge Induction Enhancement: Equipped with an 18mm ultra-thin flat probe, installed 5mm close to the edge of the metal ring. The electromagnetic induction algorithm is optimized to enhance the signal recognition capability in the edge area, capable of detecting stacking differences with a thickness of 0.5mm.

Dynamic Synchronous Detection: Integrated with a high-speed signal acquisition module (response time of 0.1 seconds), which matches the conveyor belt speed in real time to ensure stable detection during the movement state.

Anti-interference Design: A built-in filter circuit is designed to address electromagnetic interference from the metal frame of the conveyor belt.

III. Implementation Results: Data-Driven Production Optimization

Three months after the equipment was put into operation, key performance indicators have been significantly improved:

Efficiency Enhancement: Manual sampling inspection was eliminated. The assembly line cycle time was reduced from 10 seconds per piece to 7 seconds per piece, with monthly production capacity increased by 120,000 pieces.

Cost Saving: The mold replacement cycle was extended from 3 weeks to 6 weeks, cutting annual maintenance costs by 40%. The equipment investment payback period is about 6 months.

IV. Customer Testimonial: From Detection Pain Points to Quality Assurance

"The Atonm 900E Metal Double Sheet Detector has solved the long-standing edge detection problem that plagued us. Now we can confidently produce high-precision hollow components," said the technical director of the enterprise. He added that accurate double-sheet detection not only improved product qualification rate, but also strengthened customers' trust in the enterprise's processing of complex components. The related order volume has grown steadily in 2024.
