Over the last 20 years machine vision inspection systems have grown rapidly to become an important and integral part of manufacturing and logistics operations. With machine vision systems providing greater flexibility and wider automation opportunities for manufacturers, being able to identify defects, provide product sortation, barcode reading, end-of-line vehicle inspection, product checking, robotic production etc.
The latest machine vision systems include 3D that can scan products moving at high speeds and as there is more uptake of this type of equipment they have become much more affordable.
L.A.C. Conveyors & Automation provide vision inspection system capability to your industry. With our own experience and partnerships that allow us to pull together the correct system at the right price. Our large and experienced in-house team of design engineers work closely with the sales team and customer to ensure that the system works perfectly.
Concept drawings and modelling can be produced to help a customer understand how the finished article will perform. Once this has been agreed, small scale testing of the design can be done to physically prove its functionality.
L.A.C. working in partnership with Kawasaki Robots UK who not only supply robots to L.A.C. but also a fully comprehensive support service and Envisage Systems who are a vision systems integrator that provide a bespoke service for many of our vision systems put together a mock-up of an end-of-line vehicle inspection system for a global industrial vehicle equipment supplier to show how a robotically controlled vision system could read and check cab systems to ensure that parts have been correctly installed and work properly. The system scanned selected items, recording and storing images for proof of functionality. Sample images of screen shots of the vision checking are below along with a video of the demonstration system in operation.
Correct use of machine vision systems in an end-of-line set-up helps not only significantly improve productivity but also delivers greater accuracy of work output by identifying defects prior to customer receipt.
Recent installations include a vision system to read barcodes on a pallet conveyor system, a vision system on a food grade stainless steel twin lane modular belt conveyor to ensure that butter tub lids are correctly seated and a correct barcode has been stamped on the tub, and a vision system to aid automated robot picking of grape punnets from a main belt conveyor and placement into cases on a secondary powered roller conveyor.
Machine vision systems can be used for the following:
- Absence/presence detection
- Automated vision testing and measurement
- Bar code reading
- Colour verification
- Defect detection
- Optical character recognition and verification
- Part verification
- Pattern matching
- Vision guided robots
Goals that machine vision can help achieve include:
|Strategic Goal||Machine Vision Applications|
|Higher quality||Inspection, measurement, gauging, and assembly verification|
|Increased productivity||Repetitive tasks formerly done manually are now done by Machine Vision System|
|Production flexibility||Measurement and gauging/ Robot guidance / Prior operation verification|
|Less machine downtime and reduced setup time||Change-overs programmed in advance|
|More complete information and tighter process control||Manual tasks can now provide computer data feedback|
|Lower capital equipment costs||Adding vision to a machine improves its performance, avoids obsolescence|
|Lower production costs||One vision system vs. many people / Detection of flaws early in the process|
|Scrap rate reduction||Inspection, measurement, and gauging|
|Inventory control||Optical Character Recognition and identification|
|Reduced floor space||Vision system vs. operator|
