TAVI.02

TAVI.02

With the TAVI.02 NELA offers an extremely powerful inspection system that features 2 glass tables and which allows for a highly precise examination of the parts from all sides. In addition to this, the TAVI.02 features an automatic part orientation identification which guarantees an efficient inspection of parts with asymmetrical sides.

Many types of rubber seals as well as precision parts made of metal or plastic, which are used in the highly sensitive areas of the automobile and aerospace industries, have to meet exceptional quality standards.

The parts are automatically brought into the inspection system by a customized feeder and are placed onto the first glass table. The upper side of the parts is then inspected by different sensor units that are always customized to meet each customer's specific requirements. Parts that are classified as "bad" on table 1 are immediately sorted out. All other parts are flipped over and are placed onto the second inspection table, where the other side of the parts is inspected. 

Since both sides of your parts are inspected directly from above and not through a glass table, TAVI.02 delivers extremely precise inspection results. 

Your Advantage with NELA:

Sensor Configuration

TAVI.02 Sensor Configuration

TAVI.02 can be equipped with a variety of different sensors, all with the accuracy of ± 1μm:

  • DIMension uses transmitted light in combination with a telecentric lens to inspect the part dimensions
  • TOPside defect detection on face sides and lateral surfaces
  • BOTTOMside defect detection on face sides and lateral surfaces
  • IN/OUTside multihead sensors for surface inspection
  • HEIGHTinspection measures the exact height of the part with a telecentric lens
  • 3Dconcheck contour measurement

 

Application

TAVI.02 is suited for a broad range of round symmetric parts and other shapes that are made of rubber and plastic in different colors. These parts are typically used in many industries. 

The part sizes that can be inspected in the TAVI.02 system range from 3,0 mm up to 80,0 mm (OD / diagonal).

The measurement accuracy is ± 1 µm and the throughput amounts to up to 36.000 parts per hour. 

The field of application of this optical inspection and sorting system ranges from O-rings, frame seals and profile gaskets, precision molded articles of all shapes, rubber compound parts and membranes to injection molded parts and blanked parts made of plastic.

Geometry measurement

Geometrical measurements on your rubber or plastics parts are carried out by high-resolution telecentric camera systems. 

Measurement of dimensions such as height, diameter, wall thickness, cross section (O-rings), distances, depths and angularity of your parts is effected by our DIMension and HEIGHTmeasure sensor units. 

For complex measuring tasks we also supply 3D-scanners. 

Surface inspection

The optical sensors in the TAVI.02 feature several illumination levels that are adjustable. Thanks to the optimized illumination, these sensors detect even the smalles surface defects on your rubber and plastics components. All camera systems used in the sensors are high-resolution and work with gray value differences.

The TOPside sensors allow for a targeted surface defect inspection on the face side of your parts, while the OUT and INside sensors assure a highly precise inspection of the lateral sides. 

All sensors used in our systems have been developed by ourselves and guarantee a very high resolution of all sides of your parts. The sensors detect defects such as pores, holes, fissures, flashes, material contamination and flow lines.
