IP67 switches speed up startup of assembly and test systems

Overview

Assembly and leak test system  

The systems are tailored precisely to the relevant components

  • The assembly and leak test systems from KMS Automation GmbH which are used in the automotive industry are built to the user's specifications.
  • IP67 switches network the individual workstations within the systems.
  • The compact devices with easily accessible cable ducts enable the stations to be quickly connected to the Ethernet network.

Customer profile

Headquarters of KMS Automation GmbH  

KMS Automation GmbH is based in Schramberg-Waldmössingen in the central Black Forest region

KMS Automation GmbH develops and manufactures among other things assembly and leak test systems, which are individually tailored to the cast components – such as gearboxes and motors – for the automotive industry and its supply industry. The owner-operated company employs around 60 people.

Application

Assembly and test system  

The distributed IP67 switch is installed directly on the sliding carriage of the workstation in the system

Depending on the component, the cast components go through several steps in which they are assembled and repeatedly checked. It is particularly important to test for leaks. The challenge here is that components which have not yet been finally assembled and which have several openings have to be checked. To carry out a leak test at part level, the parts must be optimally clamped in the station, ensuring the relevant geometry is adhered to. Test pressure is then applied to the parts by the leak test system to check whether the pressure is maintained.

To integrate different technology components – such as screwdriver controls, camera sensors, force-distance measuring systems, and operator panels – in the individual workstations, KMS Automation uses an industrial Ethernet network. At the same time, the standard provides the communication basis for a modular manufacturing concept.

Solution

FL SWITCH 1605 M12  

The FL SWITCH 1605 M12 offers five Ethernet ports in the splash-proof version

In order to be able to connect the technology components easily and directly to the network, IP67 switches from the Factoryline product range are mounted directly on the sliding carriages of the workstations. The FL SWITCH 1605 M12 devices have five Ethernet ports in the splash-proof M12 D-coded version. Pre-assembled cables enable on-site connection of the Ethernet components in the workstation. The switches are supplied via an M12 Power Connector, which feeds 24 V DC from the base frame of the station. Thanks to its narrow design, the FL SWITCH 1605 M12 saves space when integrated and also provides easy access to the cable outlets. It is also secured to the sliding carriage using two M6 screws. The spatial arrangement of the individual workstations can usually only be specified to a limited extent. Here, directly accessible interfaces between the stations using M12 connectors prove advantageous.

Although KMS Automation must implement the systems according to the specific requirements of its customers, for reasons of efficiency the company tries to use standardized technology wherever possible. This is why the machine builder focuses on using components and concepts that can be used and combined in a quick and versatile way. Pre-assembled cables are used both for Ethernet networking and to connect the sensors and actuators in the workstations. On the workstation bench, the I/O level is connected to SACB sensor/actuator boxes via M12 connectors. The base frame of the respective workstations contains the necessary control cabinet, so there is no need for a separate cabinet. Switches from the SFN series, which are installed next to the controller on the DIN rail, are used to connect the Ethernet network in the base frame.

Daniel Infantone, Head of Electrical Installation at KMS Automation, values the Plug and Play principle of the distributed IP67 switches: “The M12 switches from Phoenix Contact simplify the Ethernet connection of our components. In addition, we can connect the workstations flexibly, which speeds up startup for our end customer.”

The quality data for the cast parts is archived in a higher-level database via the Ethernet network. The parameterization of the technology components is checked and modified via a service interface that is fitted to the outside of the workstation, without the safety screen having to be opened.
