II. Product Description (Detailed Version)
The 720° Precision Connector AOI Inspection System is a fully automatic optical inspection device developed by Mingcha Zhixin (Shenzhen) Technology Co., Ltd., specifically designed for precision connectors and their key components. It deeply integrates laser interferometry, multimodal optical imaging, and non-contact precision inspection technologies. Through multi-station precision lenses, high-resolution cameras, specially designed optical paths, and proprietary inspection algorithms, the system achieves comprehensive, high-efficiency, high-precision inspection of connector pins, probes, terminals, and assemblies — covering surface appearance, dimensional measurement, end-face condition, and internal defects.

This system is specifically developed to address pain points in precision electronic component manufacturing, such as low inspection efficiency, fragmented inspection processes, and poor consistency in manual inspection. It is widely applicable to semiconductors, advanced packaging, automotive electronics, defense, communications equipment, medical devices, 3C electronics, and other fields.

1. Working Principle & Technical Architecture
The system consists of multi-station precision lens modules, high-resolution industrial cameras, specially designed optical paths, proprietary inspection algorithm software platforms, and precision motion control systems. Through multi-angle, multi-station synchronous imaging and intelligent image analysis, it achieves 720° blind-spot-free inspection of connector assemblies — covering outer cylindrical surfaces, end faces, inner holes, and key structures — while the product is horizontally placed.

• Multi-Station Parallel Inspection: Multiple high-precision lenses and camera combinations synchronously capture images of different product areas, significantly improving inspection efficiency.

• Proprietary Inspection Algorithms: Deep learning-based visual inspection algorithms accurately identify micron-level defects while effectively eliminating interference, ensuring stable and reliable inspection results.

• Non-Contact Precision Inspection: No physical contact with the workpiece surface throughout the process, avoiding secondary damage — particularly suitable for high-precision electronic components.

2. Applicable Product Range
The system is suitable for inspection of the following precision connectors and assemblies:

• Applicable Shape: Straight rod shape, horizontally placeable.

• Applicable Materials: High-precision electronic components (e.g., copper alloys, stainless steel, and other metals).

• Applicable Size Range:
  (1) Length: 6.0mm – 18.0mm
  (2) Outer diameter: 1.0mm – 1.7mm
  (3) Hole depth: <5.0mm

3. Core Inspection Items
The system completes the following inspection items in a single pass:

III. Core Product Advantages

(1) 720° Full Coverage — No Blind Spots
Conventional inspection methods typically only inspect the outer surface of connector assemblies, leaving blind spots. This system uses multi-station precision lenses and specially designed optical paths to simultaneously cover the outer cylindrical surface, end faces, and inner holes — achieving true 720° no-blind-spot inspection, ensuring defects at any angle cannot escape detection.

(2) One Pass, Complete Inspection
Integrates more than ten inspection items — including dimensional profiles, surface defects, end-face conditions, and internal foreign matter — into a single process, completing full inspection in one pass. This eliminates efficiency losses and quality risks caused by using multiple machines and multi-step processes.

(3) Ultra-High Efficiency, Matching Production Scale
Production takt time up to UPH 2,500 – 10,000 pieces/hour, easily matching high-speed automated production lines. Prevents defective products from reaching downstream processes from the source, helping customers achieve 100% full-inspection quality goals.

(4) High Compatibility — One Machine, Multiple Uses
The system features an expandable design. Through quick changeover and corresponding parameter configuration, it accommodates multiple models and sizes of connector assemblies. Simply adjust settings to achieve rapid switching between different product specifications, significantly improving equipment utilization.

(5) Smart Software & Stable System

• Intelligent Inspection Software: Clean and intuitive interface, easy operation; supports customizable inspection standards, data statistics, and report export.

• Equipment Self-Diagnostics: Automatically alarms, stops, and indicates fault points when equipment mechanisms or software anomalies occur, facilitating rapid maintenance.

• Multiple Safety Protections: Obstacle-sensing stop devices within the automated workspace prevent personnel or foreign objects from entering; fully insulated wiring throughout; independently designed power control cabinet ensures operational safety.
