Vision Sensor Solutions

---

SPEDE Vision solutions also use Keyence vision sensors to prevent errors in identifying, counting, packing and labeling finished parts. When workers are new to a job, tired or distracted, they can confuse similar-looking parts and cause serious problems downstream for both customer and supplier. 

Infrared or Visible Light Sensors? 

• For part validation and counting, SPEDE uses Infrared vision sensors 
• For color detection, or detection of color variations in parts, SPEDE uses Visible Light sensors

Functions Included: 

• Parts validation - validate parts for correctness at Pack and Re-pack
• Parts validation - validate tool is correct for a particular process
• Scrap detection - validate parts leaving production as good, scrap or rework; divert scrap pieces when interfaced to a conveyor
• Parts counting - read the 2D serial number on a part for accurate piece counting and individual part traceability 
• Parts counting - count non-serialized parts accurately 
• Packing - increment the running total of good parts towards a pack count 
• Packing - validate a dunnage layer is correct and complete before the next layer can begin
• Labeling - trigger a container label when the pack count / dunnage is correct
• Parts traceability - vision can read /record the serial number on a part for granular traceability back to Raw and forward to finished item / shipping

How a SPEDE Vision Sensor Solution works:

A Keyence vision sensor is "trained" to recognize a part number based on the unique characteristic of that part, using image capture and pixel analysis. 

No PLC Needed!

A SPEDE vision solution does not require a PLC to supply part number data. This means vision sensors can be used at Pack and Re-pack stations where no PLC is present, in addition to at the production machine if parts are packed there. A touchscreen PC will display an image of the part being scanned as the part passes under the sensor via conveyor, or is presented by hand. If SPEDE determines the part is correct, it will increment the count towards the pack count. If not, it can optionally trigger the part to be diverted via conveyor and increment a scrap count increase. An audio/visual signal will alert the operator of the exception to prevent the packing of wrong or scrap parts.
