The “Profile Matcher” tool of the OXM profile sensors allows profile matching to be implemented quickly and easily straight in the production process. Teaching-in of good parts and tolerance windows is simply via the intuitive web interface at the push of a button. The measurement result can be converted directly into a switching signal and transmitted straight to the machine. There is no easier way to implement inline quality control.

The relevant evaluation range can be set very easily via the OX profile sensor's web interface which allows suppression of interference signals. Furthermore, the sensors ensure that only the relevant part of the object is measured. A separate ROI can be defined for each tool (measurement task). 

The object to be measured can move within the measuring range, or the distance from the object to the sensor can change (e.g. due to movements in the conveyor belt) without influencing the measurement result. This insensitivity facilitates alignment and positioning of the sensor and contributes significantly to reliable sensor performance in the application.

The OX profile sensor offset can compensate installation angles up to ± 30° towards the object. The results are output as if the sensor was installed perpendicularly towards the object. The sensor can even process dynamic position changes. This way, any change in the angle between object and sensor during the measuring operation will be automatically corrected by the sensor.

Product features can be checked reliably in the production process even if the objects are moving on a conveyor belt. Any prominent point of an object can serve for position tracking. For example, maximum height, any edge or the centre of a circle detected can be used. This will compensate position changes of the measured object.

Field of view: Measurement range in the direction of the laser line (X-direction)
Measurement range: The measurement range is the distance range within which the sensor takes measurements
Measuring distance: The measuring distance is the distance from which the sensor takes a measurement
Z-direction: Distance from sensor to object (height information)
X-direction: Direction of laser line
Y-direction: Direction of movement (for measurement on a conveyor belt)

Robot fine positioning
The OX200 profile sensors guide the robots to the correct position in a container system for rackless storage and handling. The high speed is the key challenge here. The sensor is connected directly to the robot without external software. Signal transmission to the controller takes place via IO-Link in this case.

Robot fine positioning
An OXM200 sensor measures the position of the hooks on a suspension device and then navigates the robot arm with pinpoint accuracy to the correct position for attaching injection-moulded parts. The compact, lightweight housing and simplified wiring (one-cable solution via Power over Ethernet for power supply and data transmission) ensure the flexibility required at the moving robot arm. Easy integration allows for quick commissioning.

Positioning
The blue laser beam of the OXM200 ensures precise, height-based position control of metal gearwheels during the production process. This makes sure the gearwheels are fed in the correct orientation for optimum subsequent processing. The sensor sends a direct signal to the machine to reject the bad part.

Inline quality control
Immediately after the bending process, the OXM200 measures whether the bending angle is within the specified tolerance threshold. The measurement result is transmitted directly to the control system thanks to simple data exchange.

Inline quality control
In the production process of e-cigarettes, a metal film needs to be wrapped around the cigarettes. During the process, OX100 sensors measure the offset of the 4-mm-thick metal film, completely immune to reflections. 

Inline quality control
Thanks to its extreme reliability even towards dark objects, the OX200 profile sensor allows for non-contact height control of black rubber seals at a very low tolerance threshold of only 2 mm. The solution was not only gentler on the material but also more cost-effective than the tactile measuring instrument used previously.
