High-speed monitoring of critical assembly processes
01 November 2011
Machine builder, Orwin chose an HBM MP85ADP amplifier to monitor assembly operations in an active engine mount assembly cell that it has built for an automotive component supplier. Active engine mounts reduce noise and vibration within a vehicle passenger compartment by sensing engine vibration and adjusting the mount’s stiffness to compensate.
The MP85ADP is a key quality control component on this assembly line as it measures applied forces and displacements during a crimping process – a process regarded as ‘critical’ by Orwin’s client. The amplifier is fast - processing data at the rate of 300 fitting cycles per minute – and offers total reliability even in the fastest production lines, where it is capable of identifying any peaks or spikes in the process for swift identification of failed parts.
Another factor that influenced Orwin’s selection of the MP85ADP was the ability to set up to eight measurement tolerance windows. The user can define these windows and track progress in terms of displacement and force using the force-displacement monitoring curve so that any flaws occurring during the crimping process are readily detected and the component withdrawn from downstream assembly operations. The MP85ADP is fieldbus enabled and equipped with digital inputs and outputs allowing easy integration with the assembly automation system.
The MP5ADP offers a number of useful functions, including a data export facility that enables manufacturing data to be transferred to a remote server for storage. The automotive component manufacturer is thus able to access this data remotely in order to obtain information, as and when required, on all or specific parts that have passed through the assembly process. Another useful feature of the MP5ADP is a barcode capability that ensures complete traceability of components – an essential requirement as far as Orwin’s client is concerned.
While this machine is capable of change part tooling, it is primarily used to produce two crimping variants, a right- and a left-hand, both equal in size. The machine can be used to produce additional variations if needed.
