Compact and industrial

With their dimensions of just 130 x 59 mm, AX30/AX40 Imagecheckers help you

realise the growing demand of downsizing equipment.They permit space saving

DIN-rail installation in a switching cabinet or direct mounting at the inspection site.

All interface connectors are located on the front side, which makes it easy to install

and service the systems. Furthermore, they have an impressive record in industrial

safety, which results also from the fact that they do not employ any mechanical parts

such as fans or hard disks.

Precise and reliable

Being the successors to our successful A-Series Imagecheckers, AX30/AX40 systems

inherit proven image-processing technology built up over many years. These high-

precision devices ensure advanced quality inspection of your products, since they

include colour data in the evaluation process. They are designed as stand-alone

devices with a proprietary operating system and a dedicated inspection firmware.

The systems are ready for operation immediately after power up and can provide

inspections 24 hours per day, 365 days a year.

Powerful dual camera inspection

AX Series Imagecheckers include a dedicated 32-bit RISC CPU that secures a high-

performance inspection level. Besides the short response time, the systems enable

very powerful inspection algorithms, such as those used for the newly developed

contour matching. They detect objects reliably, even if they partially overlap or if

ambient light changes.

AX30/AX40 process the images of up to two colour CCD cameras in parallel and

output inspection results after a few milliseconds.

Micro-Imagechecker AX30/AX40

Software Highlights

Human eye-like sensitivity

The colour recognition/extraction

algorithms of AX30 and AX40 are based

on the LCH (luminosity, chroma and

hue) mode, which covers all colours a

human eye can recognise. This mode

allows for colour recognition more

similar to that of the human eye than

conventional RGB-mode colour

extraction.

Colour Detection, Presence Checking

Measures the area of the specified region or pre-defined

colours to detect foreign objects, perform presence checking,

sort or count objects.

Inspection examples

Size Measurement

Grey-scale based inspection functions such as edge finders

allow the system to measure dimensions, angles, diameters,

radii, etc. with sub-pixel resolution.

Numerous advantages

Independent evaluation of luminance, saturation and hue

Low influence by variation in luminance

Higher recognition certainty

Reliable detection of objects barly distinguishable

in grey colour pictures

Colours like green,

cyan or yellow can

hardly be

distinguished in

grey colour pictures.

Only a colour system makes reliable

control possible.

Colour image processing opens a new world of possibilities.

37709_ax30_40_ENGL 06.04.2005 14:51 Uhr Seite 6

Position detection

Several algorithms in the systems are made for precisely

detecting the position of an object.

x/y coordinates and the rotation angle are typically output.

Matching

Advanced matching functions such as contour-matching and

smart matching1) can be used to identify or to validate object

details reliably and efficiently.

1) AX40 only

Fast and easy setup

Our newly designed user interface

allows you to set up your inspection

routine quickly. The clearly structured

screen with its pull-down menus,

semitransparent spreadsheets and

indicators makes it easy to configure the

AX30 or AX40 to each individual

application, even for non-experts.

Special Features

Colour tone diagram

Fine adjustment for color inspection is

possible. Even when colors resemble

each other, the target color alone can be

extracted to enable highly accurate

inspection.

Mask

The shape of the inspection area can be

set to match particular targets. Also,

mask area settings can be combined so

that efficient inspection can be carried

out just for a required part.

Print screen

You can save setting displays or

displays that occur during operation as

bitmaps on a memory card. This is

convenient for creating documents or for

verifying previously shot images.

360° contour-matching

By calculating contour lines and judging,

stable positional detection is possible

even for hidden, overlapped objects that

have been difficult to detect up to now.

Thanks to this, better yields are

achieved.

AX40Previous

Versatile rotational and positional

adjustment

Highly accurate and reliable inspection

is realized by automatically adjusting

object orientation and stop-position

deviation. Since adjustment is done

using grey scale data, the AX40 shows

its strength when it comes to changes in

brightness. Complicated adjustments

are possible because of the priority

adjustment function.

Additional Features of the AX40

Smart matching

Grey scale matching makes sub-pixel

positional detection possible

Furthermore, shape inspection, such as

for the detection of chipped objects, can

be carried out simultaneously with the

grey scale difference processing

1 System – 4 inspection modes

AX40 commands four different inspection modes: colour, binary, grey-scale and differential image processing. Combined with a

large pool of ready-made and easy-to-configure inspection functions such as 360° contour-matching and smart matching, AX40

can handle nearly any inspection task.

Data monitor

Up to 50 inspection results are displayed

on the monitor in chart form for operator

verification. Also, threshold adjustment

(upper and lower limit values) can be

changed on the data monitor without

entering them in the setting menu.

Statistical support

Data can be tracked, e.g. as maximum

value, minimum value, average value,

and number of NG (no-good) results.

Maximum, minimum, average and other

OK judgment values can be verified,

which is useful as a guide for making

upper and lower limit settings.

Numerical calculation/judgement

output

The computation function, which has

been troublesome up to now, now can

be easily made, even by beginners.

Also, operation has become even easier

thanks to the ability to set both

numerical calculation and judgement

output on the same screen.
