Application

Vision system for OCR of connecting rod part numbers

The Application

Accurate part identification without manual reading

Vision systems ensure highly accurate, consistent data capture — essential for tracking and verifying components in high-precision applications. By automating the reading process, they reduce human error and make part identification faster and more reliable.
The vision system sends real-time data directly to an HMI, giving operators instant access to part information for seamless monitoring and quality control — improving traceability and minimising costly rework or downtime.

Key Factors

Performance at a Glance

Fast, repeatable reads shown on the result screen

6 ms

OCR tool time shown on the result screen.

16 ms

Total job run time per read.

Deep learning

Deep learning-based OCR reads the part number.

Operation

How the inspection works

The connecting rod is held in a fixture; a push button serves solely as the trigger that starts the process.

01

Load and trigger

The connecting rod is held in the fixture and the operator presses the push button.

02

Pneumatic positioning

The rod is pneumatically lowered into position for inspection.

03

Read and transmit

The camera captures and reads the part number, sending it directly to the HMI for real-time monitoring.

04

Unload

The rod is pneumatically lifted back up so it can be unloaded from the fixture.

Final Result

Part number read and displayed in real time

Technology Used

Hardware behind the inspection

Zebra FS20 Scanner

Captures and reads the part number on the connecting rod.

Push Button

Serves solely as the trigger that activates the inspection cycle.
