Vision Inspection & Reject Machine

Maintaining consistent quality on high-speed production lines is important, as even minor defects in capping or labeling can affect product performance and damage brand reputation. To ensure accuracy at every stage, our intelligent vision inspection system uses a multi-layered approach supported by AI-driven analysis and high-resolution imaging:

• The dual-inspection system features a high-precision capping module that analyzes thread engagement down to 0.01 mm, detecting tilt or missed locks with 360° coverage. Simultaneously, the labeling unit captures issues like misalignment, missing labels, damage, or contamination in milliseconds, helping maintain a flawless, professional appearance across every unit.
• Once a defect is identified, the system activates a fast-response reject mechanism that removes the faulty item within 300 milliseconds, without stopping the production flow. The inspection system maintains a 99.99% rejection accuracy rate, ensuring product consistency without interrupting production.
• A smart management hub powers real-time SPC quality mapping, pinpoints root causes of recurring issues, and integrates with MES systems to automatically optimize production parameters. This data-driven feedback loop can reduce quality-related losses by more than 40% annually.
• Thanks to its high processing speed and broad adaptability, the system meets strict quality requirements in industries such as food, pharmaceuticals, personal care, and household chemicals.

• Cap Inspection
  After capping, the system examines each bottle to detect potential issues such as missing caps, off-center positioning, or visible cap damage. Bottles that fail to meet the set sealing criteria are automatically rejected to ensure consistency and safety.
• Label Inspection
  Once labeling is complete, the inspection system checks for label-related defects including missing labels, incorrect placement, contamination, or surface damage. Any irregularities are identified within milliseconds and removed from the line without affecting overall production flow.
