Photovoltaic Modules Screws Inspection Machine

Overview

As global solar production scales, the demand for defect-free fasteners used in photovoltaic module installation becomes critical. Even minor dimensional deviations or microscopic surface cracks can compromise installation strength, durability, and system safety.

This Photovoltaic Modules Screws Inspection Machine provides a fully automated, AI-assisted solution for inline quality control. Equipped with multi-angle cameras and deep-learning algorithms, the system captures and analyzes every screw — eliminating human error and ensuring traceable, data-driven quality management.

• Photovoltaic module mounting screws
• Inner hex bolts
• Self-tapping screws
• Bolt sets with flat washer and spring washer

Key Features

Integrated deep-learning algorithms detect micro-defects invisible to traditional vision systems, ensuring high precision and reliability.

Processes up to 400 screws per minute without sacrificing accuracy or repeatability.

One system supports inspection of three screw types:

• Inner hex bolts
• Self-tapping screws
• Bolt sets with washers

Multi-camera layout captures all critical angles for head, shank, and threads, achieving complete visual coverage.

Pneumatic sorting ensures rapid separation of OK/NG parts, supporting continuous production without downtime.

Built-in inspection reports, defect image storage, and result statistics ensure traceability and process optimization.
