Completeness check
The completeness check is a quality assurance procedure . It is checked whether all the components required for a process to run properly are available. Depending on the application, checklists or image processing methods can be used as aids .
Assembly processes
The completeness check in assembly and production is primarily a presence check; it is checked whether all components of a component or assembly are in the right place. In addition to checking the presence of, for example, screw connections or weld seams . The negative completeness check describes the detection of undesirable assembly results such as dirt or cracks.
In automation technology , the completeness check is used using color sensors , industrial cameras , light barriers and intelligent cameras. The product to be produced is checked for complete and proper assembly.
For example, a completeness check is carried out on child safety devices for sockets , with the presence of the actual safety element, a spring and the correct position of this spring being checked with an intelligent camera.
A few years ago this task was done by workers. He checked the products visually . Today, the completeness check is largely carried out using modern image processing . This increases the reliability of the system and the costs for the tests can for the most part be greatly reduced.
For safety-relevant components, it is particularly important that tests are always carried out according to the same criteria, which often cannot be guaranteed in the case of critical tests by a worker.
For this purpose, image processing uses various algorithms that allow objects such as screws, prints or electrical components or modules to be reliably and automatically recognized. With good object recognition it is possible to carry out a completeness check.
Exemplary areas of application
- Control of welds
- Assembly inspection of screw connections or riveted connections
- Defect detection during or after production
- Testing of blanks in textile finishing
Administrative processes
In administration, the completeness check describes the availability of all documents and documents required for a notification.
Many delays in administrative processes are caused by incomplete or non-existent documents, the completeness check enables missing information to be noticed promptly and requested again.
Exemplary areas of application
- in the approval process for building applications and similar administrative acts
- Checklists for suspected contaminated surfaces
- in the approval process for the approval of biocides
