To keep pace with today's rapidly evolving society, machine vision inspection technology has become indispensable. It plays a crucial role in industrial automation, especially for large-scale manufacturers. By replacing traditional manual visual inspections with machine vision, it identifies product defects, monitors production quality data in real time, reduces defective output, ensures consistent product quality, and enhances market competitiveness.

The most fundamental feature of machine vision systems is enhancing production flexibility and automation. In hazardous working environments unsuitable for human operation or where manual visual inspection fails to meet requirements, machine vision is commonly used as a substitute for human vision. Additionally, in large-scale repetitive industrial processes, machine vision inspection methods can significantly improve production efficiency and automation levels.

Machine vision inspection classification:
1. According to the inspection function, it can be divided into: positioning, defect detection, counting/omission detection, and size measurement.
2. According to the carrier on which it is installed, it can be classified as: online inspection system and offline inspection system.
3. According to the inspection technology: there are usually size measurement technology, appearance surface defect detection, OCR technology, etc.

Machine Vision Inspection Application Cases:
1. Battery Product Visual Inspection: Detection of appearance defects such as foreign objects, scratches, indentations, poor earing, contamination, corrosion, dents, burned earing, poor inkjet printing, blurred characters, etc. in battery products.
2. PCB Circuit Board Visual Inspection: Inspection of the appearance, size, pins and surface mount components of PCB circuit board products, as well as integrity checks for solder joints, orientation errors, etc.
3. Precision Components Visual Inspection: Measurement of dimensions such as length, width, height, and diameter of precision components like screws, bearings, and gears, and detection of surface defects such as scratches, marks, damage, etc.
4. Electronic Components Visual Inspection: Dimension measurement of components like connectors, capacitors, and resistors, detection of defects such as pin offset, deformation, shortage, etc., and character detection of printed characters.
5. Food Packaging Visual Inspection: Inspection of the appearance integrity of food packaging, barcode recognition, sealing performance inspection; beverage sorting and color selection, liquid detection, recognition of production date and expiration date characters; empty bottle damage and cleanliness inspection on filling lines, etc.
6. Pharmaceutical Packaging Visual Inspection: Dimension measurement of pharmaceutical plastic bottles and glass bottles, detection of defects such as damage, black spots, etc.
7. Textile and Clothing Accessories Visual Inspection: Detection of surface defects of textiles such as non-woven fabrics and towels, including holes, stains, loose edges, unsealed edges, loose threads, trademarks, etc., as well as dimension measurement, appearance defect detection, and label character detection of textile and clothing accessories (such as metal buttons, plastic buttons, etc.).
