Not every company does it all
Many only do 1 of the 3 disciplines
![Page 12: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/12.jpg)
Collaboration Is Key
• Companies are beginning to leverage each other’s
strengths
– Customers receive products designed to work together
• Omron Industrial Automation and PBC Linear
collaboration
– Omron controls and PBC Linear mechanicals
• By combining strengths, it is easier for customers
– This focus on strength helps each company to reduce energy
spent on non-core products
![Page 13: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/13.jpg)
Why Customers Want Convergence
• Reduced selection time
– Shorter design cycles
• Fewer technical support conflicts
– Less finger pointing between vendors
• Common communication protocols
– Faster communication between devices
• Vision systems that speak directly to the motion
controller
– Easier to program and less hardware

The Problem
• System used manual adjustments for change-over
– Time consuming
– Inaccurate
– Enclosure integrity
– Limited space
![Page 18: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/18.jpg)

fewer moisture related repairs
• Smaller footprint for total enclosure
• Parts count reduction by 40%, justifying the
added cost

INSPECTION
IN MOTION
![Page 24: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/24.jpg)
The Application

• Inspecting cultures
• Logging the data
– Date & Time
– Color
– Physical Size
• Diameter
• Area
– Change from previous size
![Page 25: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/25.jpg)
Sample Culture
![Page 26: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/26.jpg)
The Problem
• Manual process
• 24/7 human monitoring
– One hour increments
• Manual measurements
– Subjective measurements, not typically repeatable from
one person to the next (due to frequent odd shape/size)
• Image logging data base manually input
– Time intensive & data entry error prone
![Page 27: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/27.jpg)

The Solution
• Cartesian robot
• Trajexia controller
• X and Y planes
• Low profile, high precision linear actuators
• FZ Vision System
• Vision system can auto guide motion controller to
ensure optimal image capture (offset move)

Inspection in Motion
![Page 32: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/32.jpg)
AUTOMATED STORAGE
& RETRIEVAL
![Page 33: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/33.jpg)
The Application
• Automated pharmaceutical dispensing machine
• Robot picks drug to be dispensed
• Vision system records bottle barcode, locates edge
and calculates offset movement distance
![Page 34: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/34.jpg)
The Problem
• Incorrect dispensing is a major liability
Complicated by…
• Mechanical Tolerances
– Inexpensive frame creates
huge tolerance stack up
• Recording Barcodes
• Label Verification
![Page 35: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/35.jpg)
The Solution
• The Cartesian Robot was installed with a home
sensor located on a sheet metal component
• The vision system provided final move
coordinates to the controller
• The vision system reads the barcode which is
then verified against the order
• The vision system also verifies the printing
on the label
• The vision system stores applicable images/data
using onboard PC (for liability reasons)
![Page 36: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/36.jpg)
![Page 37: Motion and Vision Convergence](https://reader030.vdocument.in/reader030/viewer/2022032514/55d4e44abb61eba85f8b4660/html5/thumbnails/37.jpg)
The Result
• The vision system’s ability to do edge detection and
calculate offset moves reduced assembly tolerances
and decreased assembly cost
• The motion and vision interface ensure accuracy of
the medicine picked
– Allows for minimized levels of liability
• Fast, accurate medicine dispensing without the
need for costly pharmacist staff
