Previous situation/problem
In industry, vast quantities of small standard parts are produced. Only a fraction can be analyzed by means of statistical process control.
This sampling inspection does not provide valid results regarding the actual product quality and may lead to a complete production batch not being usable.
Conceptual Formulation
Our customers had a clear specification:
- 100% test or measurement of all parts
- sorting the parts (rejecting of all NOK parts, sorting in error classes)
Solution
The "ZU SORT" glass turntable system can be equipped with several camera stations.
The parts are fed in with different techniques, for example, as bulk material with a vibrating base conveyor, but other conveying techniques are also possible.
The parts are seperated on the glass turntable and precisely measured or tested.
The OK inspected parts are blown off, the NOK parts are stripped off.
With the verification mode a cyclic test equipment monitoring (after a certain time or part counter) is automatically scheduled. It monitors if defined good parts are good and bad parts are bad and whether there are contamination or impairments that influence the test.
By default the sorting of NOK parts is possible according into two error classes.
After inspection, the parts are passed on as bulk goods or packaged in bags, blisters or similar packing units(depending on the customer requirement).
