Solutions Using Keyence Vision Sensors

---

The SPEDE vision solutions can use a variety of vision sensor and/or camera technologies for part validation, scrap detection, counting, and pack / re-pack control, depending upon the specific application requirements. 

Keyence infrared vision sensors can be used for part validation and counting. 

If your application requires detecting color or color variations in parts, then visible light sensors can be used. 

Using Vision Sensors for Quality Control

Vision sensors eliminate human errors. When workers are new to a job, are tired, distracted or confused, they can mis-identify parts that look alike; mix defective parts with good parts; or mis-count parts when packing a container, causing serious problems for both customer and supplier. 

 SPEDE Vision Solutions Automate these Functions:

• Parts Validation - validate parts for correctness at Pack / Re-pack
• Tool / Part validation - validate tool or part is correct for a particular process
• Scrap detection - validate parts leaving production as good, scrap or rework, and when interfaced to a conveyor, divert scrap pieces 
• 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. 

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 use at the production line 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.
