Machine vision technology has afforded computers the ability to identify and recognise a variety of characteristics of the item in its view. This technology is used across a wide range of different industries and applications. The aim of machine vision is to mimic or improve upon the performance of the human eye.
Guidance means a vision system can locate the position and orientation of a part and report on its accuracy relating to a specified tolerance, angle and more. This information can then be used to measure and verify assembly. Guidance can also report the location and orientation of a part in 2D or 3D space, to the robot which locates that part, or a machine controller that aligns the part.
Guidance is critical for aligning to other vision tools as well. Parts can be presented to a camera in unknown orientations during the production process.
A vision system for gauging calculates distances between two or more points or geometric locations on an object to determine if these measurements meet specifications.
MACHINE VISION READS IN CODE AND ALPHANUMERIC CHARACTERS
An optical character recognition (OCR) system reads the alphanumeric characters while optical character verification (OCV) systems confirm the presence of a character string.
Manufacturers use DPM applications, as they mark a character string or code directly onto a part, a technique used for error-proofing. This application also allows for better asset tracking, monitoring, quality control and authenticity verification. By mapping out the genealogy of a part, warranties and sub-assembly can be directly labelled.
Although barcodes are the widest accepted forms of retail checkout or inventory control, traceability information requires a much larger area than what barcode surfaces allow. The introduction of 2D codes like Data Matrix means more information can be included on virtually any finished product.
Machine vision reads:
An inspection vision system is responsible for detecting irregularities, defects, flaws and contaminants. This technology is also used for inspecting a product’s completeness.
It ensures a match between product and package, and it conducts checks on seals, caps, rings, etc.
ClearView offers bespoke solutions that we create with leading-edge components. Our expert engineering teams have in-depth knowledge of all things machine vision and they will ensure the solutions they create address all your needs.
A machine vision system will offer your comprehensive quality control. These systems can look for defects based on how the object is supposed to look.
As with all machines, components can end up needing replacement. You can expect to have to replace lenses to illuminators and software libraries within the lifespan of your machine visions solution. The great news is that replacement components can easily and quickly be found.
A camera without any specific data input or automated instructions is just a camera. You won’t be able to pull out the data necessary to inform you about key features about the object the camera is viewing. With a machine vision system you can process the image and extract all the necessary data which is communicated and which is indicative of a pass/fail. This way your following actions are informed and strategic. Actions such as a product reject trigger is worthwhile.
