Achieving No Double-Feed Production: Multi-Station Stamping Robots with Metal Double-Sheet Detector

Multi-station stamping robots are high-efficiency, versatile machines used for multi-station forming tasks such as blanking, drawing, punching, bending, flanging, and trimming. They are widely applied in tools, home appliances, auto parts, cookware, lighting, canning, filters, bearings, and sheet metal industries.

In these applications, double- or multi-sheet detection during material handling is critical. Occasionally two sheets may be picked simultaneously, and if double sheets enter subsequent stamping stages, they can cause line stoppages, equipment failures, and quality issues. To ensure smooth production and stable quality, Metal Double-Sheet Detectors are required.

Metal Double-Sheet Detectors use advanced sensing technologies and algorithms to accurately distinguish single and multiple sheets by detecting differences in material, thickness, and area via magnetic flux. When double sheets are detected, the system issues a signal so operators can remove the double sheets from the line, preventing downstream problems. These detectors are designed to be robust against gaps, flatness, height differences, lighting, temperature, humidity, and metal debris.

Additionally, when material changes are frequent, Atonm Metal Double-Sheet Detectors support multiple stored recipes so the line can switch detection profiles without manual parameter adjustment, greatly improving adaptability and flexibility.

Combining multi-station stamping robots with Metal Double-Sheet Detectors enables efficient forming while ensuring product quality, line stability, and flexibility—an important approach for manufacturers to enhance competitiveness through automation.
