Common Problems
   
What causes bad stamping?
   
  - Broken or missing Marking Pin
   
  - Fatigued spring
   
  - Insufficient Marking Tip sharpness
   
  - Incorrect distance from marking head to the part (too far or too near)
   
  - Insufficient impact strength
   
  - Air pressure failure
   
  - Number already stamped
  Consequences
   
Number Stamped is a legal requisite
   
  - Car being returned by customer
   
  - Total loss chassis caused by undetected bad number stamped (in various territories)
   
  - Large amount of repair hours spent to replace or remark chassis or engine
   
  - Unsatisfied client
  Items to be checked
   
- Detect errors on the number stamped for future possible reparation doing an OCR verification
   
- Verify the correct assembly of VIN data onto the vehicle/car
   
- Advise whether the reference country allows remark process
   
- Checking tip sharpness profile
   
- Depth measurement guaranteeing legal requirements
  OCR Vision System
   
- To recognize printed/marked information previously unknown, machine vision system are use to perform   Optical Character Recognition (OCR).
  OCV Vision System
   
- To make sure high information is printed and the data is complete, machine vision system are use to perform   Optical Character Verification (OCV).
  Summary
 
    - The Control and Vision PC actively participates in the marking process, controls data to be marked and       verifies that data has been correctly stamped.
 
       • Broadcasting connection: Data from the production line vehicles are received.
 
       • PLC network: Control the installation status, robot marking status etc. This communication allows the          process between both system to synchronize perfectly.
 
       • Cameras: Proportion the images to the vision card contained in the computer.
 
    - Provide 100% marking quality verification – to track along the entire assembly line using strategically       positioned cameras.
