IMAGE PROCESSING SOLUTIONS FOR ASSEMBLY CONTROL AND LETTER READING

Functions:

ISW GmbH offers powerful multi-camera image processing solutions for assembly control and plain text reading on the basis of its own configurable platform. The system shows its strengths in combined applications for assembly control and plain text reading with high demands on speed, component size, varying ambient conditions and a high number of variants. The system is used in assembly and packaging plants.

Typical tasks are assembly checks on very large and complex assemblies to check for completeness, part accuracy, mounting position and part fit, which is usually associated with reading tasks. A further typical task is the completeness check and plain text reading of packaged medicines, medical technology products and foodstuffs.

The solutions are usually based on cameras with 640 x 480 up to 1200 x 1600 pixel resolution, also line scan cameras with resolutions up to 8000 pixels can be used. Applications with up to 20 cameras or more are possible, reading speeds up to 1200 parts/min were realized. The systems are factory programmed and parameterized. The powerful software is based, among other things, on the Halcon image processing software library, whose development environment enables rapid development of machine vision and image analysis applications and offers an extensive program library. For data transmission, the system is equipped with all customary industrial interface formats.

Application range:

The image processing solutions are integrated into the production line or used in stations for end-of-line inspection. An important field of application are tasks for combined assembly control and plain text reading in assembly and packaging systems with high demands on speed and recognition reliability, under difficult conditions or with high complexity. Typically, 2D applications are implemented for evaluation in the grey value range, which can occur in all production scales up to very large series.

The area of application in the pharmaceutical industry is the testing of packaged medicines and medical technology products such as the level testing of ampoules or the reading of clear text and OCR texts on packaging. In the case of foodstuffs and luxury foods, for example, quality checks are carried out on blister packs for inclusions and cracks and on sales packaging for completeness and content. The general user industries are the automotive and automotive supplier industry, the pharmaceutical industry, medical technology and the food and beverage industry.
