Electromagnetic solutions could offer high workloads. But those units are not designed to operate in a high duty cycle environment, when continuously activated and deactivated, the winding of the electromagnet starts to heat and deteriorate. This after several month operations resulted in higher current consumptions and burned cables. 

The switchable magnet AR series offered by PES perfectly meets the above-mentioned expectations. They combine power and compactness for full structured bin picking capabilities.

Indeed, the robot shall slip into the parts to touch the magnet working surface that are hard to access but EOAT size is also critical for access in bin corners at different depths.

Indeed, there are dozens of different spring designs from small ones to larger ones with some exotic shapes. Handling those part with a robot is not an easy task and using classical gripper can rapidly increase the level of picking complexity as the spring shows different gripping points depending on its orientation. In this context, magnets are the perfect gripping solution. 

For this specific purpose, PES has developed a modular EOAT solution based on its magnetic gripper product line.

The EOAT is made up of two different modularity levels.

Thanks to Magswitch M10AY ASC magnetic grippers PES offers a shallow field solution that saturates at 1mm depth! Benefits of pneumatically actuated magnetic grippers (flexibility, reliability, energy efficiency) come to serve your destacking application. Used with the sheet fanner tool which allows performing a pre-separation of the sheets on the stack and avoids blanks sticking issues, this solution can reach up to 100% single sheet destacking performance in all conditions. 

Among those new tools, once can find magnet grippers. They consist in a pneumatically or electrically actuated mobile magnet placed above a fixed one in order to activate an outer magnetic field that allows handling of ferrous parts while being extremely compact. Magnetic power is already installed in the product so the need for energy is minimal. And, unlike common preconception, residual magnetism of handled parts stays low.
