In the course of this, the connection of the grippers was changed from a force fit to a form fit. The groove of the gripper is pushed into a C-groove of the robot, clamped with a plate and screwed. The weak points of the fastening could thus be eliminated. Due to the modular structure, it is now possible that the grippers can be used in both processing steps on the robot systems.
Additively manufactured grippers exceed expectations:
No wear and tear on suction grippers noticeable!
“Not a gimmick, but real means of production at BEULCO GmbH & Co. KG!” Emphasizes Lutz Schopen. The new additively manufactured grippers meet the requirements in 99% of the applications. Some of the suction cups have already been in use for over 200,000 cycles and show no measurable wear. The high loads from fast movements have no effect on stability, nor do cooling lubricants with which the components come into contact.
Furthermore, the procurement times (external procurement) could be reduced significantly from 4-6 weeks to 1-2 days, in the ideal case to 24 hours. There are also gigantic savings. A total of £200,000 has already been saved with over 330 printed gripper pairs and suction grippers. The Mark Two 3D printer paid for itself in less than two months!
