Unmanned Crane Intelligent Lifting

The unmanned crane electro-permanent magnetic lifting device is specially designed for automated handling. It uses electro-permanent magnetic technology to generate strong magnetic force in an instant when energized, adsorbing steel and other metal materials. After power failure, the magnetic force still exists to ensure safe and stable handling. With the cooperation of unmanned cranes, it can achieve precise positioning and fast lifting, improve logistics efficiency, reduce labor costs and safety risks, and is suitable for steel mills, warehouses and other scenarios.

Automatic Identification and Sorting System

Heavy industry workpieces are characterized by large shape differences and a wide variety of types. To ensure stable grasping of various types of workpieces, this product uses a self-designed dot matrix electro-permanent magnetic end-effector gripper, which has the advantages of simple structure, high universality, single-point control, stable performance, and plug-and-play. It can achieve flexible grasping of massive workpieces. At the same time, intelligent control based on vision can ensure that the end-effector accurately adsorbs irregularly shaped workpieces and avoids adhesion to surrounding waste materials.

Welding clamping

Automated robotic arm clamping—Electro-permanent magnet welding fixture, is a very suitable adsorption tool in the steel plate welding process; and can fix steel plates of different sizes and shapes, making the welding process safer and safer. Automatic material picking, positioning, and transfer for fully automated production, electro-permanent magnetic grippers can be optionally configured according to the design magnetic force size for automatic flipping and tapping processes, small size, large suction force, fully meet the requirements of multi-directional layout and prevent welding deformation, one clamping can complete multi-faceted processing; the internal coil does not have a heating problem, eliminating maintenance, and running at near-zero cost;

Industry pain points

Low labor efficiency

Unable to ensure personal safety
High labor cost input and low efficiency

Traditional fixtures are backward

Vacuum suction cups have poor adaptability
Grippers and clamps easily damage workpieces

High energy consumption

Electro-permanent magnets are 95% more energy-efficient than electromagnets

Electro-permanent magnets only require 0.1-0.3 seconds of pulsed current

Some applications of electro-permanent magnets in production lines

Large piece picking and stacking

For large metal workpieces, electro-permanent magnets can easily cope. It can generate enough magnetic force to firmly adsorb large pieces, pick them up from the production line and accurately stack them in the designated area. The operation is simple and fast, reducing the labor intensity and safety risks of manual handling, while improving the neatness and stability of stacking.

Cutting loading and unloading

When cutting and loading and unloading, the electro-permanent magnet can accurately adsorb the steel plate and quickly place it on the cutting machine workbench to ensure accurate positioning. After cutting, it can quickly lift the finished product or waste material, realizing efficient loading and unloading. Its strong and stable magnetic force can adapt to steel plates of different thicknesses and sizes, improving cutting efficiency and accuracy.

Large piece picking and stacking

Small parts picking and stacking

When handling small metal parts, electro-permanent magnets also perform well. It can adjust the adsorption force according to the shape and size of the small parts, accurately pick up single or multiple small parts, and neatly stack them. Its fast response and flexible operation characteristics improve the efficiency of small parts handling and avoid omissions or damage that may occur during manual operation.

Welding clamping

In the welding clamping process, the electro-permanent magnet can quickly fix the metal components to be welded in the accurate position to ensure welding accuracy. Its stable and reliable clamping force can reduce vibration and displacement during welding and improve welding quality. Moreover, the operation is simple and can quickly switch the clamping state to adapt to the needs of different welding tasks.

Solution

20-ton port electric permanent magnet lifting device

In modern port logistics systems, the efficiency and safety of steel plate handling directly affect overall operational efficiency. Qianhao Magnetic Electric's 20-ton electro-permanent magnetic lifting device, developed specifically for port scenarios, provides a revolutionary solution for gantry crane operations, leveraging its intelligent magnetic adjustment system and six-fold safety protection technology.

Steel plate lifting devices of a certain steel structure plant

Qianhao electric permanent magnet lifting tools have been widely recognized and repurchased by customers for lifting steel plates, steel pipes, cast iron pipes and other ferromagnetic workpieces. When using electric permanent magnet lifting tools to lift steel pipes and cast iron pipes (round ferromagnetic workpieces), only a portion of the contact surface needs to be attached to lift 8 tons, 10 tons, 16 tons, and 32 tons.
