Why Do 9 Out of 10 Customers Choose "Auto-Focus" Barcode Readers?

On high-speed production lines, are you often troubled by these issues?

→ Varying product sizes causing frequent "out-of-focus" barcode readers?
→ Fluctuations in conveyor belt positions leading to a sharp drop in barcode recognition rates?
→ QR codes on curved or wrinkled packaging that just can’t be accurately captured?

Fixed-focus barcode readers can no longer meet the challenges of flexible production. However, Evoc Intelligent Barcode Readers, with their revolutionary millisecond-level auto-focus technology, have become the ultimate solution to overcome the "distance dilemma" in industrial barcode reading!

Adapting to Target Distance Variations

Scenario 1:
On assembly lines, the position, height, or orientation of products may vary (e.g., boxes of different sizes, pallets of different heights, or tilted products). The target distance also changes when AGVs approach or move away from shelves.

Evoc Intelligent Barcode Readers' auto-focus feature can adjust the lens focus in real-time and quickly, ensuring the barcode/QR code image is always captured with optimal clarity, regardless of whether the target is near or far. No manual adjustments or preset fixed focal points are needed, significantly improving flexibility.

Handling Uneven or Curved Surfaces

Scenario:
Barcodes may be attached to curved surfaces (e.g., bottles, pipes), wrinkled packaging, or uneven metal surfaces.

Evoc Intelligent Barcode Readers' auto-focus feature can adjust the lens focus in real-time and quickly, ensuring the barcode/QR code image is always captured with optimal clarity, whether the target is near or far, greatly enhancing flexibility.

Improving Read Rates and Accuracy

Scenario: Blurry barcode images are a leading cause of read failures.

Evoc Intelligent Barcode Readers' auto-focus optimizes depth of field or quickly scans different focal planes to find the clearest part of the barcode for reading, improving the ability to decode irregular surfaces.

Simplifying Installation, Debugging, and Maintenance

Scenario:
Installing fixed-focus barcode readers requires precise measurement and adjustment of the distance between the reader and the target, making the debugging process cumbersome. If the production line layout changes or product specifications vary, re-adjustments may be necessary.

Clear images are the foundation of accurate decoding. Evoc Intelligent Barcode Readers' auto-focus ensures images are always at optimal sharpness, significantly improving the first-read success rate, reducing misreads or failed reads, and ensuring smooth production or logistics operations with accurate data.
