Cylinder head assembly production line
16 Robots, 2.88 Minutes,
1 Cylinder head
It takes less than three minutes for a complex cylinder head to be assembled from a series of sometimes very delicate individual parts and to leave the line. This system, built by Paul Köster GmbH, makes it possible to perform multi-step assembly operations in no time flat and check components for leaks in six different test cavities in a total of seven individual tests.
The nearly 25-meter long system for a well-known supplier of a leading car manufacturer in southern German was built and commissioned for the customer after detailed planning, design and production in Medebach. The highest precision, intensive coordination and deep process know-how ensure a reliable process for 18 individual operations.
Everything is provided by Paul Köster GmbH in this turnkey project, from the initial system designs to the overall comprehensive system.
Some INDIVIDUAL OPERATIONS at a glance
THE PROJECT IN FIGURES
Numerous interfaces were optimally coordinated for a smooth flow and consistent cooperation of the individual cells.
The complexity and multi-faceted nature was reflected not only in the individual assembly and testing operations, but also in the coordination and timing of all related processes.
Facts
- System approx. 25 m long
- 7 process steps
- 18 individual operations
- 16 robots
- Cycle time of <2.88 min per cylinder head
INDIVIDUAL OPERATIONS IMPLEMENTED
This project required all our core areas in order to ensure a functioning and well-tested component assembly.
The transport and provision of parts and individual components holds all individual processes together. The assembly stages were coordinated with the interspersed leak tests of the various test cavities so that, in the end, all essential steps run into each other rationally.
