MAGNETIC GRIPPER FOR ROBOT APPLICATIONS

Goudsmit Magnetic has developed a magnetic gripper or robot-end-of-arm-tooling which is used for picking up or holding items such as punched steel parts, blanks and perforated steel sheet in robotic applications in the automotive industry. The ultralight magnetic gripper is fitted with permanent magnets and can be used in grippers on robot arms. The magnets can be switched on and off pneumatically. This enables the system to pick up and transport even very thin steel sheets one at a time. The rubber pad at the end ensures that the work piece does not slide during vertical pick-up and prevents the work piece from being damaged. This easily installable system is already in use by a number of large car manufacturers.

Vacuum technique

The use of a magnetic gripper on robot arms replaces the traditional vacuum technique. A disadvantage of vacuum grippers is that they are susceptible to malfunction and subject to wear. Furthermore, the vacuum cups must be positioned correctly, because when they are positioned even partially over a hole in the metal sheet they do not grip at all. The electromagnets used by other manufacturers are not a good solution for this problem, because they are so heavy that they reduce the lifting capacity; a magnetic gripper with permanent magnets is considerably lighter. Moreover, the gripper does not wear and has a longer service life than vacuum grippers.

Schmalz Technology Development - Vacuum Generation without Compressed Air - Flexible and Intelligent

• Vacuum generation that's 100% electrical; • Integrated intelligence for energy and process control; • Extensive communication options through IO-Link interface; Schmalz already offers a large range of solutions that can optimize handling process from single components such as vacuum generators to complete gripping systems. Particularly when used in autonomous warehouse, conventional vacuum generation with compressed air reaches its limits. Compressed air often is unavailable in warehouses. Schmalz therefore is introducing a new technology development: a gripper with vacuum generation that does not use compressed air. The vacuum is generated 100% electrically. This makes the gripper both energy efficient and mobile. At the same time, warehouses need systems with integrated intelligence to deliver information and learn. This enables the use of mobile and self-sufficient robots, which pick production order at various locations in the warehouse. Furthermore, Schmalz provides various modular connection options from its wide range of end effectors in order to handle different products reliably and safely.
