Vision Sensor Solutions

---

If workers are new, tired or distracted they can mis-identify similar looking parts and cause serious problems downstream - internally and for the customer. Depending on the application requirements, SPEDE Vision solutions use either USB cameras or Keyence vision sensors to prevent errors in identifying, counting, packing and labeling finished parts. 

Infrared or Visible Light Sensors? 

• Infrared vision sensors are used for part validation and counting 
• Visible Light sensors are used for color detection, or detection of color variations in parts 

Functions Include: 

• Parts validation for correctness at Pack and Re-pack
• Tool validation that tool is correct for a particular process
• Scrap detection of parts leaving production: good, scrap or rework; scrap is diverted with a conveyor interface
• Parts counting by reading the 2D serial number on a part; ensures accurate piece counting and individual part traceability 
• Parts counting of 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
• Container 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.
