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
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).
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.
