Machine loading with sensitive gripper
In a compact cell, it is necessary to work with a very complex gripper that cannot simply be replaced by a spare gripper in the event of a crash.
The survey provides the customer with a backup of their hardware. Hardware recovery is now possible at any time by re-measuring after a crash or gripper replacement. There is no need to spend time re-teaching, the system is secure.
Integration on the second line without reteaching
Prevention of downtime
Shortening the commissioning
The customer uses a KUKA KR125 to insert throttle bodies into a CNC machining centre. This is where the surfaces of the housings are milled. The unique aspect of the machine is that it is a very sensitive and complex gripper. This is necessary because the space in the cell is so limited that a more robust gripper cannot be used. Among other things, the gripper is folded in for certain movements so that the robot can reach its positions.
At the time of commissioning, the plant was processing five different types of enclosures. In total, however, the cell is designed for around 120 types. The enormous variety of types also increases the number of programme items. Due to the complexity of the gripper, it cannot simply be replaced by a spare gripper in the event of a crash, as it is difficult to manufacture a mechanically identical gripper. This would stop production for several days while the programmes were re-teached.
For a measurement, a master component with four measuring balls is inserted into the gripper as far as it will go and the gripper is closed. Now a robot programme only needs to move to five points to measure the balls. The result is the gripper’s new tool frame.
