Functions of Optical Inspection Machines

Optical inspection machines utilize imaging and image processing to automate inspection, measurement, and identification on high-speed production lines.

1. High-Precision Dimensional Measurement

• ফাংশন: Non-contact measurement of length, width, height, diameter, hole size, and spacing.
• আবেদন: Verifying if parts are within drawing tolerances.

2. Surface Defect Inspection

• ফাংশন: Identifying various surface flaws.
• Defects Detected:
  • Scratches, cracks, dents.
  • Stains, contamination, foreign material.
  • Printing defects.
  • Assembly errors.
  • Coating irregularities.

3. Identification and Classification

• ফাংশন: Reading product markings and sorting based on features.
• আবেদন:
  • OCR/OCV: Reading and verifying dates, lot codes, serial numbers.
  • Barcode/QR Code Reading: For traceability.
  • Color Recognition: Sorting or checking color consistency.
  • Shape Sorting: Identifying different product models.

4. Positioning and Guidance

• ফাংশন: Precisely calculating an object’s location and angle.
• আবেদন:
  • Robot Vision Guidance: Providing coordinates for precise pick-and-place.
  • Alignment: Guiding high-precision alignment in lamination processes.

5. Completeness Inspection

• ফাংশন: Checking for missing components or incomplete assembly.
• আবেদন: Detecting missing pills in blister packs, missing pins in connectors, missing labels, etc.

Summary: The optical inspection machine acts as the “intelligent eyes” of the production line. Its core function is to enable 100% in-line inspection, transforming quality control from manual sampling to an objective, fast, and quantifiable automated process. This ensures product consistency, boosts efficiency, and enables full traceability.
