In line with its strategy of providing Mechatronic Multiple Inspection Systems (M 2 IS), QMTMultiSens is an anechoic test environment combining different inspection methods with the ability to manipulate the device under test (DUT). In its first version, QMTMultiSens is configured for opto-acoustic analysis: it combines industrial vision with acoustic acquisition and analysis.
In order to be able to analyze the acoustic characteristics of a device in a reproductive and reliable manner, the use of an anechoic chamber (or "anechoic chamber") is essential. This experimentation environment has walls which absorb sound waves, thus causing no echo that could disturb the measurements. The anechoic chamber is also isolated from acoustic disturbances coming from the outside, namely airborne and structural noise: certain vibrations are transmitted by the structure (walls, ceilings and floors) and others by air. The performances are an aerial isolation (50dB), with complete decoupling, and solid.
It is possible to run your hands through the equipment to handle the product while maintaining sound insulation. It is thus possible to characterize the acoustic and optical response of a product during its handling.
The optical system consists of a 2 MPixel camera with a 105 x 60mm field of view. A diffuse lighting allows the acquisition of high definition images or films.
A high sensitivity sensor allows the acquisition of the acoustic signal from 6.5 to 80dB, with a bandwidth of 5Hz to 20kHz.
A first example of application is in the field of high-end watchmaking, where the setting and control of striking watches is a major challenge. Three main reasons make the task very complex:
QMTMultiSens is therefore the table equipment suitable for a high-end manufacturing workshop and which meets these three needs. It allows the watchmaker to adjust the ringing complication using an opto-acoustic measurement and analysis tool. Automatic quality control over different test durations is also feasible and easy. QMTMultiSens allows the following analyzes in an automatic or semi-automatic way:
The equipment is versatile and can be adapted to other applications in watchmaking but also in other industries. The software functions required by the different applications will be added according to the needs of the applications.
The software makes it possible to control the whole as a stand-alone system with the possibility of interfacing an external command or exchanging data with the customer's databases. It is one of the key elements of the system, as it is endowed with advanced means of analysis of images and sounds.
Qmt products can be customized from both a hardware and software point of view. The first level of software customization is the addition of additional functions or the development of a personalized function. It is also possible to personalize the equipment, for example by modifying the field of vision or by adding incident lighting.
On the basis of qmt products, it is proposed the realization of labeled product on behalf of our customers who can be private or marketed by themselves
