Needle adjustment

Needle tolerances compensated automatically

The dispensing result is mostly determined by the correct centred position of the tip of the needle. To compensate for the tolerances, any deviations have to be measured after every needle change. The XYZ dispensing needle adjustment involves a fully automatic sensor for aligning the dispensing needle position along all three coordinate axes. Via a mechanical probe and two forked light barriers, deviations from the actual dispensing axis are determined in the length, as well as in the bend of the dispensing needle and are compensated automatically by the software. The sensor is programmed with a dispensing macro. A corresponding example macro is included in delivery.

XYZ sensor

Three-dimensional probe sensor

Simply swivel into the work area and increase the production quality within seconds, or just check the dimensional stability:

We navigate quickly, simply and easily over all obstacles with the DATRON XYZ sensor. With the help of this sensor, a measurement field in the Z plane is generated in a freely definable reference grid. This way, workpiece surfaces or reference surfaces can be measured and deviations in Z can be recorded and automatically corrected. The dispensing nozzle is guided according to the recorded offset using this technology, which guarantees the optimum dispensing height at all times. The measurement fields can be saved and loaded again later, as needed.

Workpiece Sensor

for non-pure production

The workpiece sensor is an inductive proximity switch, which reacts to different codes on the workpiece support. In in-line mode, this sensor makes it possible to machine different parts with one machine; thus a non-pure production is possible.

The sensor automatically detects the code on a workpiece support and allocates it to a certain program.

Up to seven different codes can be detected with a triple-sensor.

Level sensor

Monitoring the cartridge contents

The level sensor continuously monitors the level of the material to be dispensed and ensures that the storage tank is exchanged in time. A magnetic sensor detects the piston position of the pneumatic cylinder here, which exerts preliminary pressure on the material to be dispensed. Once a previously defined position has been reached, the sensor gives a signal indicating that the cartridge should be exchanged soon.
