"Industrial cameras and image inspection equipment have too much functions and they are too expensive..."
"Don't have the budget for multiple machine vision systems..."
"Want to try to see if automation is possible for the time being..."
The image processing system"MoMaVi" developed by Mars Tohken Solutions solves various problems in all types of inspections at low cost. In this article, we will introduce the features of MoMaVi and its innovative use beyond the manufacturer's expectations.
MoMaVi is an image processing system that can perform various inspection of precision parts and count the quantity of objects utilizing a smartphone. Mechanization not only aims to eliminate false positives and omissions caused by visual inspection, it is worth mentioning that all types of image processing at low cost with a simple device configuration using a smartphone camera can be achieved, without the need to introduce expensive equipment such as "image inspection equipment," "industrial cameras" and "dedicated lighting”.
<With MoMaVi, the following can be inspected>
■ Presence inspection : Checks the presence or absence of things that should be there.
In addition to these, it can be used for various other inspections such as "counting the number of colors," "surface inspection," etc., depending on the idea.
The following is an example that proves MoMaVi's ability to perform inspections that previously had to be performed visually or with expensive specialized equipment.
SANYO KASEI (THAILAND) LTD., a Thai subsidiary of Japanese chemical manufacturer Sanyo Chemical Industries, Ltd., has implemented a liquid viscosity measurement system using MoMaVi.
Before
The moments the water surface passed the upper and lower lines were visually observed and measured using a stopwatch.
Problems faced by conventional measurement methods
・Variation in measurement results occurs
・It is difficult to concentrate on other tasks during measurement
・Failure to do so would result in starting over from the beginning
・It is time-consuming and labor-intensive to perform measurement and viscosity calculation
・Specialized viscosity measuring equipment is expensive
After
MoMavi was deployed. The following benefits were realized by using a smartphone camera to determine and automatically start and end measurements.
◎No variation in measurement results
Start and end timing is determined mechanically in units of 0.001 seconds. The same results are obtained no matter by who or how many times the measurement is performed.
◎Other tasks can be performed while measuring & Worry-free
After pressing the start button for the measurement, let MoMaVi take care of a series of tasks. Not only other works can be done at the same time without worrying about the end time, but no need to redo it, which dramatically improves work efficiency.
◎Automatic viscosity calculation & data management
No more time and effort spent on multiple calculations and careful checks with a calculator. After MoMaVi calculates viscosity, it automatically sends data to LIMS (Laboratory Information Management System) and issues COA (Certificate of Analysis). By linking MoMaVi with the data management system, further operational efficiency was achieved.
The company's LIMS is handled by Freewill-Mars Tohken Co., Ltd., and Thai subsidiary of each other have been associated for a long time.
