Length, profile and position measurement systems for easily deformed profiles can be applied to various types of products such as gaskets, tapes and hoses in flexible materials.
When it comes to gaskets, for example, you need a system that can accurately measure final length after assembly, so you need high-precision components that can handle variations in profile shape.
To meet these needs, numerous devices suitable for dimensional control are available. Among these is the laser scanner, which is used to measure the complete 3D geometry of the product and is particularly suited to the inspection of objects with complex or irregular surfaces.
The vision systems also allow the precise detection of the dimensional characteristics even if they do not automatically identify the geometric details. They use technologies such as line and matrix cameras along with artificial intelligence and computer models to automatically detect errors in the most complex parts.
Optical inspection technology can provide a high level of accuracy in dimensional measurement and control of the most complex parts. Systems based on laser sensors, cameras and artificial intelligence can accurately analyze all dimensional characteristics individually or simultaneously. ù With the help of advanced hardware such as CCD and CMOS industrial cameras together with computer vision, optical inspection systems allow for accurate monitoring of dimensionally critical elements such as sharp edges, burrs and geometric errors during industrial production.
The combined use of industrial automation with technologies such as optical profilametry leads to a cornerstone of Industry 4.0: the statistical control of quality in real time.
This process would include ancillary instruments such as high-performance digitized video cameras, AI (Artificial Intelligence) capabilities dedicated to visual recognition, laser sensors to suppress environmental effects such as vibrations or movements.
The length and position gauges for easily deformable profiles are digital instruments capable of accurately detecting the geometry of the profiles. These devices consist of a combination of laser scanners, vision systems, linear or matrix cameras that analyze and detect the dimensions, curvature or inclination of the surface.
These technologies are fundamental in the numerical control industrial machinery industry, offering maximum precision in operations.
Furthermore, the use of advanced systems such as artificial intelligence and optical inspection technologies allow users to process and interpret the data collected by the meters efficiently and accurately.
The technology can be applied to multiple industrial sectors, qualifying processes such as 3D measurement and surface analysis. This has contributed to the rapid spread of Industry 4.0 and is a key element in industrial automation.
The most common tools for checking the size, curvature or inclination of the surface are glacially called "optical measurements".
The most widespread method involves the use of laser sensors capable of correctly detecting the profile to be measured thanks to the ability of visible light to bounce off a reflective surface without undergoing significant variations in terms of dimensionality. In this way it is possible to accurately calculate the geometrical characteristics of the desired profile without incurring errors due to mechanical, chemical or thermal anomalies which could influence the original dimensions.
Finally, lately much attention has been given to the technique known as “optical profiling”.
This technique is based on a three-beam laser which generates a focused beam with a variable angle according to the profile to be measured; the reflector emits light responses that are read by cameras connected to the device itself, thus creating an accurate digital model of the profile to be measured.
Unlike the previously mentioned procedure, profilometry can also be used on more complex surfaces since it does not require any type of compensation for the deformability due to the material and the thermal variations to which the product to be inspected is subject.
