Methods to Prevent Double-Picking by Robot Arms and Introduction to Atonm Double-Sheet Detector

In industrial production, robot arms pick up sheets, and pickup accuracy is critical to product quality and efficiency. However, double- or multi-sheet pickups sometimes occur, severely impacting production. The main causes include material properties, stacking issues, improper robot settings and environmental factors.

Common prevention methods

1. Optimize stacking and placement: ensure sheets are stacked neatly and use separators or racks to reduce sticking.

2. Precisely tune robot parameters: adjust suction force, pickup speed and position according to sheet material and thickness.

3. Strengthen maintenance: regularly inspect suction components and clean the workspace to avoid dust and debris causing multiple pickups.

Even with these measures, double-pick issues can persist. Atonm's Double-Sheet Detector offers a smart, precise detection solution.

Atonm Double-Sheet Detector — an efficient overlap-detection solution

Working principle: the detector uses advanced sensor technology based on electromagnetic induction and eddy current principles to analyze magnetic field changes as metal sheets pass the sensor. When double or multiple sheets are detected, the detector triggers an alarm and quickly signals the robot to stop, preventing extra sheets from entering subsequent processes.

Installation and use are simple: mount the sensor near the robot end-effector, perform basic tuning, and monitor via a user interface. Key advantages include high detection accuracy, fast response and broad compatibility with various robot brands and systems.
