THE ADVANTAGES
The advantages of machine vision applications are in the objectification of measurements, the independence from the human factor, speed and accuracy, and in the possibility to integrate measuring equipment into a production line and thus directly and automatically influence the production parameters.
BASIC PRINCIPLE OF MACHINE VISION SYSTEMS
BASIC PRINCIPLE OF MACHINE VISION SYSTEMS
Cameras capture the image of an examined object and evaluate it according to the prescribed algorithm. Based on the result of the evaluation, the control system performs an action, most often it is the marking or elimination of a defective piece.
OPTICAL METHODS OF MEASUREMENT AND SUBSEQUENT PROCESSING OF DIGITALIZED IMAGE
enable the industry to solve most of the problems associated with measurement:
- shapes,
- dimensions,
- colours,
- prints,
- location,
- number of identifications,
- surface quality,
- their defects and deviations
.. and other problems associated with general quality control in production.
INSPECTION OF INSERTED PARTS
The cameras located above the loading nests make it possible to check the presence of all the parts necessary for the subsequent process, and they also allow us to check the parts‘ positions and thus prevent possible collisions.
READING CODES AND RECOGNIZING ALPHANUMERIC CHARACTERISTICS
In addition to reading standard 1D and 2D codes, machine vision can be used to "read" so-called bit coding, and to read alphanumeric characters (so-called OCR) on product bodies.
The advantage of using machine vision is that it provides the opportunity to combine the above tasks and to expand them further.
CONNECTOR CONTROL
Machine vision has a wide area of applications in the field of connector production.
Camera systems are used for the control of individual components entering production, the control of inter-production operations and, last but not least, for the control of a completely assembled product. Flows, seals, insulation, crimps, paints, pin positions and much more are commonly controlled
COMPONENT INSPECTION
Camera systems enable non-contact fast measurement of product dimensions.
Using appropriate optics and calibration procedures, optical systems can provide results in absolute values.
INSPECTION OF PAINTS, ADHESIVES AND PASTE
Machine vision is used to check the presence and position of paint, glue and paste on products.
Very often, these substances contain fluorescent particles which, when illuminated by UV light, are visible in the visible area and which can then be safely detected.
GUIDANCE OF PRODUCTION TOOLS - BONDING
It is often necessary to specify the positions of semi-finished products in order to further process them.
One example is the position of the wire, which must be mounted in the correct position.
By calibrating the camera and the bonding tool located on the servo axes (or on the robot arm), the desired results can be achieved.
An additional bonus is the ability to control the "design" of the final bond
3D SCANNERS FOR ACCURATE MEASUREMENT
3D scanners are among the most accurate devices in the field of machine vision.
They are autonomous and calibrated systems that allow measurements in real units in the order of microns.
