Speaking of robot gripper, many would think of vacuum cups as they are widely used in robotics. While in handling ferrous steels, like laser metal cut parts, they are not the right ones. Here, HVR MAG will tell you how to choose the right end of arm tool for your robots in cutting system.
In steel cutting system, especially laser cutting, those small metal cut parts of various shapes and sizes, have to be removed from the cutting table and stored respectively, which was a very demanding job.
Magnetic gripper is an essential end-effectors tool of a robotic system. It serves as the robot’s hand and allows the robot to manipulate ferrous objects for proper safely gripping. They are typically used for sorting metal laser cut parts in intelligent manufacturing workshops.
Take the following robot gripper, for example, it was designed and manufactured according to the specifications of these cut parts by HVR MAG.
It was composed of many small magnetic gripping heads. The gripping force was engineered according to the varying sizes and weights of different cut parts. To unload the cut parts piece by piece off the cutting table, without grabbing up other near part, the magnetic type of robot gripper has incomparable advantages:
- It only needs one surface to grab the object.
- The grasping speed is fast.
- It is flexible since it does not need different designs for different parts.
- It can grip parts with holes which is not possible with vacuum grippers.
- It requires minimal maintenance.
Due to the unique features of metal cut parts, vacuum cups are unfit for the handling job, as they cannot pick up porous workpieces or parts with holes, let alone mechanical gripping fingers.
Besides, this magnetic type of robot gripper, mounted on Cartesian or robotic arm, does not consume electricity in gripping state. It only needs power to switch the magnetic gripping force on and off. That is to say, it can remain gripping of the cut piece even in a sudden power outage.
During the energy crisis, power shortage is becoming more and more frequent. For that reason, manufactures have to make some changes to get prepared for that situation. Using the electro permanent magnetic type of robot gripper, custom designed, will certainly make your intelligent manufacturing more efficient and flexible.
