Industrial Robot + Atonm Metal Double-Sheet Detector — Applications in Stamping

Stamping is a plastic forming technique that uses a press and dies to produce parts with required dimensions. As labor costs rise, industrial robots for press feeding are increasingly used, but double-sheet overlaps during feeding remain a safety and quality concern. This article outlines an approach to detect double-sheet overlaps.

Overview of stamping process

Stamping is a plastic forming technique that relies on sheet material, dies and presses. It enables high production efficiency and is well-suited for automated production lines. Processes like shearing, leveling and compound die operations can perform multiple steps in one press. Traditional stamping requires continuous manual handling for each operation, which raises safety and labor concerns and makes it difficult to meet modern complex production needs. Therefore, automation is necessary to maintain quality, increase productivity and ensure safety.

Industrial robots in stamping

Modern manufacturing has introduced high-speed automation that replaces manual feeding. Whether using dedicated machines or manual feeding, efficiency and safety issues persist. To build efficient automated lines or flexible transfer systems, industrial robots are used for feeding. Robots offer:

1. Automated feeding and unloading for stamping production.

2. Reduced labor costs and improved safety.

3. Reduced manual workload and steady production rhythm.

However, during robot feeding, suction cups may sometimes pick overlapping sheets due to sheet surface tension, causing double-sheet feeding.

Effective solution for overlapping sheets

The Atonm double-sheet detection system is widely used with robotic feeders to accurately detect overlapping metal blanks and prevent defective sheets from entering the stamping process.
