  Perfect Light for the Car Interior

Light Guide Rods
More and more cars today are equipped with light guide rods in their interior, the so-called ambiance area, for example in door panels, dashboard, center console, and roof lining. Through semi-transparent flat strips these light guide rods guide the light into the interior of the car. Any inhomogeneity in the light guide rod would influence the scattering behaviour of the output light. When driving in the dark, a passenger in the car interior would notice this as a bright or dark position along the light strip and would be disturbed by it.

Inline Detectors Offer a new Method of Component Marking
In the course of a comprehensive digitisation of industrial production and processes (keyword: Industry 4.0) a new method of marking manufactured components now offers previously undreamed-of possibilities. By way of an individual marking (a random distribution of fluorescent particles on the object surface or in the object matrix) a virtual key can be generated and can be used to save product-relevant data e.g. on the server (or in the cloud). Due to the random distribution of these fluorescent particles this "star code" represents a kind of "digital fingerprint". Already a few particles in the viewing field are sufficient to guarantee safe and robust recognition, with little required memory space per code.

  Perfect Gloss Measurement!

Hand-held units for measuring the gloss level have been successfully used in the industry for years, and three viewing angles have been established as a standard: 20°, 60° and 85° measured from the vertical axis. The paper industry is an exception here and primarily uses viewing angles of 45° and 75°. The gloss level is determined by measuring the direct reflection at the object surface to be inspected.

  Choose the Right Side

95% of all the industrially produced flat glass today is made using the float glass process. In this process, molten glass is continuously fed into a bath of molten tin. Due to its lower specific weight the molten glass floats on the smooth tin surface, and on a long tin bath forms a uniformly thick and extremely smooth film. The glass side that faces the molten tin is slightly contaminated with tin, which has corresponding effects on subsequent float glass processing steps such as coating of the glass surface.
For the further processing of float glass it is therefore important that the surface that is contaminated by the tin bath can be distinguished from the so-called fire side (fire polishing, during float glass production the glass side facing away from the molten tin is heated).

  Problems With Folds?

In the production of oil and air filters for the automobile industry these filters must reach the required throughput rate, which is achieved by folding the filter material so that it provides a large filter surface on a minimum of space. Depending on the filter type there are differences in the fold depth and in the numbers of folds.

  Welding Seam Detection With Edge Detectors

For the detection of welding seams, contrast or color sensors would seem to be the proper solution, because in most cases the welding seam optically shows a clear difference from the surrounding product surface. In everyday practice, however, it turns out that these methods involve frequent readjustment and reparameterisation.

  Connected to the Future!

Up to now it may have been sufficient for a sensor manufacturer to provide systems with digital outputs, a 0V to +10V analog voltage output, and a 4mA to 20mA analog current output. In the foreseeable future, however, communication between sensors and programmable logic controllers (PLCs) primarily will be performed in digital serial form with a correspondingly high data rate. The future belongs to the so-called Industrial Ethernet.

  Detection of Transparent Edges

Conventional detectors particularly reach their limits when they have to detect and count stacked transparent objects such as plastic drinking cups of plastic caps. Especially in the process of packaging, however, it is of great importance to place the exact number of objects in a packaging unit. Such problems now can be solved with the RED series (a RED-110-L was used for this application).

  A Hazy Problem?

At first everything seemed to be quite clear, just another measurement task that we surely would manage without any problems with one of our GLOSS series sensors. According to the descriptions provided by the customer it seemed to be gloss grade measuring task, and at the beginning the only question seemed to be at which angle measurement should be performed: 20°, 60° or 85° from the vertical?

  Perfect Copy Counting

When cartons, magazines, or single sheets are packed, it must be ensured that each package has the correct number of items. In most cases such material is transported in shingled form before, as with magazines, newspapers or advertising prints, it is packed by means of a compensating stacker. Depending on the thickness of the individual copies and on their transport speed (up to 10m/s) the shingled stream may have differing heights in this process.

  Clear Strategy or Plain Guessing?

In the last years the spray nozzles at windscreens have seen quite some development. The jet now comes as a fan jet or spot jet. A homogeneous spray mist application onto the intended angle range is now accurately guaranteed with fan jets, as is the point-shaped jet application on the front cameras by means of exactly directed and hardly diverging spot jets.

  INLINE Color Measurement of Paint Through a 15mm Thick Inspection Glass

Usually the color checking of color paint during production primarily is done in a laboratory. A paint sample is taken, and the color of this sample is then checked by way of a thin paint layer in dry condition. This process of course takes some time, time in which paint production might run out of the permissible tolerances and thus might require time-consuming and expensive follow-up treatment.

  Accurate High-Speed Counting of Stacked Plastic Caps

Especially the counting of transparent, stacked plastic caps, as they for example frequently are used in the packing industry, usually is a highly problematic application because on the one hand the edges of individual caps are not always exactly aligned, and on the other hand copy counters that work with the reflected-light principle do not provide a reliable counting result especially with transparent objects.
