Know how for special applications

For some special application fields standard systems are not satisfying. In those cases latest engineering know how for individual modified test- and inspection systems is necessary. Ibea´s evaluation team offers many years of experience with the use of the following systems / procedures:

Used image processing procedures are: Surface- and texture analysis, 2D/3D-Measurements (Laser grill), position-independent component measurement, completeness control, barcode reading 2D/3D, decor control (black & white and colored), optical character recognition OCR

 

Multi-camera-systems
In production areas where single images do not release enough information, multi-camera-constructions are used for detail inspection. In principle each of ibea´s image processing systems is prepared for the use of several cameras. Up to 8 cameras (black & white, colored) are able to run at the same time on one single line. Those cameras record and process synchronized and join either one illumination or use additional illumination elements to inspect the product from different angles.

Between two images, ibea achieves a minimal cycle time of 7 msec. This offers the opportunity to run double image controls of one single object by using different illumination methods.

Multi-line-systems
Up to 3 production lines can be supervised by only one single control unit, which includes up to 8 cameras so that altogether 24 cameras can be controlled centrally.
Per line asynchronous images can be realized among each other. Flow control into one of the processing units is appropriate for splitting. It has to be mentioned that in practice this kind of splitting is refrained because it reduces the range of clock rate to 300-800 ppm.

Thermography
One option of image processing is to use special thermo cameras in combination with heat introduction. That kind of inspecting method is called heatflow-thermography and offers lots of opportunities for energy contribution (a.o. inductive heat, lamps, lightning, laser, ultrasonic, hot air, and microwave) and therefore another application area.

For example the following defects can be identified, tested non-destructive and contactless: bad or weak spots in invisible bonding resp. welding scratches and blow holes in cast part. This inspecting method is a cheap and secure alternative to X ray technique and can be tailored to many kinds of inspection procedures.

SeamscanSeam Scanner
A Seam Scanner is necessary for measurement and documentation of the can part, where bottom and wall are melded to a so called seam. This seam is sliced by a double-saw blade, cleaned and then positioned on a plateau. Turning the can enables an easy adjustment of the focus.
The images are used by adequate image processing software which processes an automatic measurement of 7 metrics by comparing them with pre-entered reference values. Results of this measurement and its reference values are statistically secured.

CVC Cap Vacuum Checker
The CVC Cap Vacuum Checker is a simple system for offline check of so called button-values of TO-caps. This system measures the vacuum values flip-on and flip-off fully automatically. Scheduled values for all common TO-diameters are already given by the system. For each different diameter of TO-caps (30-110 mm) corresponding adapter heads exist as accessory. Output of the measured values happens via the built-in protocol printer (optional) or via an Ethernet modem which is connected to a quality management system and can be received as accessory part.

Measurement of compound height / Laser based systems
Differences of injected compound height in PT- or TO-caps are not or hard to detect by human eyes. However the control of irregularities is enormous important because the cap does not lock correctly in case of inequalities and a contamination of the bin-content is highly probable.

The new system enables a fully automated, easy applicable compound height measurement of PT- or TO-caps of approx. 30 to 110 mm diameter. Applicable for all current compound types up to a height of approx. 10 mm. The manually placed cap is tightened by a magnet to a pre-calibrated reference area and subsequently centered in an automatically electro mechanic way. Afterwards a laser (laser resolution = ? 10 ?m) scans the compound by using a triangulation method. Measurement is finished by the output of compound height and compound lining. The detection of the compound height difference (DiP) is effected with an accuracy of 0,05 mm. Change of different cap sizes does not occur readjustment as this runs fully automated.
