System Architecture
Electromagnetic gripper manipulators are the most efficient solution for handling ferromagnetic metal sheets, profiles, and castings. Compared to vacuum suction cups, electromagnetic adsorption offers greater penetration and stability when handling rough surfaces, oily surfaces, or steel sheets with oxide scale.
For different process requirements (such as loading and unloading of laser cutting machines, and stacking of thick plates), this system typically uses a rigid boom balancer or gantry crane as the carrier.
End of Execution (EOAT): Employs an electro-permanent magnet array.
Control System: Integrates servo drive and magnetic force detection modules, supporting multi-level magnetic force adjustment.
Safety Redundancy: Built-in backup power system (UPS) and mechanical secondary protection devices.
Sensor Network: Includes distance compensation, weight sensing, and plate layer detection sensors.
Working Principle
Electro-Permanent Magnet Technology
Mainstream equipment now fully utilizes “electro-permanent magnets” instead of traditional pure electromagnets. Its core advantage lies in the fact that electrical energy is consumed only during the moment of attraction and release (approximately 0.5~1 second).
During handling, the magnetic force is provided by internal permanent magnet materials. Even in the event of an accidental power outage, the magnetic force remains, ensuring the steel plate will not fall.
Safety Protocols
Power-off protection against falling: Thanks to the physical properties of electro-permanent magnets, the magnetic force remains at 100% even after power loss.
Dual-button release logic: The release command requires simultaneous activation of two physically spaced buttons to prevent the steel plate from falling from a height due to accidental contact.
Landing detection: The demagnetization procedure is only activated when the weight sensor detects that the load has been fully released (contacting the ground or stacking position).
Application Scenarios
Application Scenarios: Heavy plate hoisting in shipyards, chassis assembly for construction machinery, and automated loading and unloading of laser cutting machines.
Efficiency Value: No manual hooking or spreading of plate gaps is required; a single person can accurately transfer multiple steel plates, increasing efficiency by 200% compared to traditional rigging.
Surface Protection: Magnetic adsorption leaves no mechanical indentations and does not damage the edges of precision steel plates, significantly reducing the cost of subsequent grinding processes.
