QUALITY CONTROL

AUTOMATIC TESTS

Implementation of Proof Of Concept (POC) for aesthetic control

To minimize uncertainties related to specific client requirements, we offer proofs of concept to validate the feasibility of a project. This process includes system definition, prototype development, testing, and the provision of a report with a presentation.

The process begins with a project study, during which we analyze the specifications and the part samples provided by the client. We then carry out an initial test in our technical laboratory (TechLab) to define the optical configuration (cameras, lenses, and lighting). The second step involves taking images to assess the feasibility of automating the inspection. This includes distinguishing between inspections requiring manual intervention and inspections based on assisted vision, as well as analyzing the typology and characteristics of the parts (machining marks, dust, material) that may affect defect detection.

The third step is the creation of a prototype of the vision system. Once the system is in place, we perform inspections and process the data using our vision software. A detailed report is then produced, accompanied by a demonstration tailored to the client's requirements.

The POC thus allows us to validate the feasibility of a solution before its full deployment, reducing technical uncertainties. By following this rigorous process, we ensure that the chosen solution meets performance and reliability criteria, thus providing a solid foundation for ensuring the success of the project and its optimal implementation.

State-of-the-art equipment

Infrastructure for QMT research and customer studies

A particular focus on optics, acoustics and data science

To meet its clients' needs in quality control and automated testing, qmt experts are sometimes required to conduct feasibility studies. Indeed, qmt offers its expertise only if the technical team considers the maturity of the technology and know-how necessary to meet the need to be sufficient. qmt refers to the ISO 16290 standard to define this maturity level (TRL: technology readiness level). If the level is not sufficient (less than 6 out of 9), the qmt Techlab is used by our experts to conduct feasibility studies necessary for the maturation of the know-how.

Our Techlab is equipped to meet the needs of both mature and new technologies.

KNOW-HOW

QMTSERVICES-CONSULTING

More than 35 years of history

A history marked by innovation. qmt developed the Multimicro in 1991, which received an award from Crédit Suisse (motorized image analyzer with automatic microhardness measurement). In 2015, qmt won the Geneva Canton Innovation Award.

Our history

Inspection of transparent parts, thickness measurements or 3D characterization

Motorized bench with chromatic confocal measurement technology

Technology and its applications

Chromatic confocal technology for optical distance and thickness measurement has been adopted as a proven method in industry and research. It is a perfect complement to traditional optics for in-plane measurement.

Description of the chosen technology

We have equipped our Techlab with a CVC (CHRomatic Vision Camera) sensor. The CHRocodile CVC line scan camera uses chromatic optics for 2D imaging. Chromatic confocal technology allows for both a significantly greater depth of field than standard cameras and an extraordinarily high lateral resolution. Since it does not require focusing, this camera saves valuable time during quality inspections. By ensuring high contrast on all types of materials, the CVC CHRocodile is ideal for inline or offline applications, such as cosmetic inspection and positioning detection.
