The grippers require maximum precision
The grippers with which the robots pick up and put down the sensitive individual parts were a challenge.
"The springs have six arms that bend if you hold them too tightly," explains Dengler. However, WAFIOS Tube
Automation is familiar with these requirements for gripping tools and has therefore developed them in-house
for the assembly cell. The overall control system, which is used to operate the system including the six KR
AGILUS via a panel, was also developed internally and has been used by customers for years. "The operator
simply programs the control system, but does not need to have any robot knowledge," emphasizes Kühn.
The workforce at Hugo Benzing GmbH & Co. KG is happy with the automation. Thanks to the "robot colleagues",
the employees have more resources for other activities in production. Especially as manual production of the
safety valves would not make sense at all due to the complexity of the assembly, the many testing processes
and the sharp increase in output. "To be the best supplier in this area, we need one hundred percent process
control. We can only achieve this through automation," says Managing Director Benzing.
