Geometry measurement

Battery sleeves

Following production, the positive pole area (Pip area) on AAA battery sleeves is supposed to be checked for surface defects, and the edge of the negative pole (Flair area) for roundness and defects (break-outs).

The check itself and the grading between OK/not OK is carried out inside a production cycle of 15 parts per second.

Soot particle filter cap

After washing and processing, three threaded holes on two types of soot particle filter caps are supposed to be checked for the presence of an internal thread, the centricity of the hole and for chips being on the bottom of the hole.

Faulty caps are detected and displayed on a monitor along with their fault characteristics.

Ladder frame

After the aluminium castings have been processed, all 28 through holes are supposed to be checked for tool breakage. This check takes place during the run.

Pipe ends

After the pipes have been processed, the pipe ends are supposed to be checked for flawed areas.

The following defects are supposed to be detected in the process:

Incorrectly chamfered pipe ends, impact marks and burrs.

The test is supposed to be integrated into the existing system and faulty pipes removed.

Moulded parts

After size 4.95mm x 8.9mm MIM parts have cooled down, these are supposed to be checked for size accuracy and cracks.

In the 1st station, the moulded parts are checked for radial run-out, for axial run-out and for gating.

After this is done, the moulded parts are fed (via a handling system) to the 2nd test station, where they are then checked for cracks and the correct diameter.

The measurement uncertainty attained for the radial run-out, axial run-out and diameter testing is 1µm.

Plastic parts

A check is supposed to made on plastic mouldings as to whether these are complete or are containing flaws an outlying moulded parts.

When using a VeriSens sensor from Baumer and area lighting with steady light intensity, the (from experience) critical areas of the component (those areas that exhibit flaws first in the event of a faulty injection process) will be scanned and compared with the nominal values.
