In the manufacturing of electrical terminals and connectors, inspection accuracy directly translates to product reliability. A terminal with a microscopic defect—a hairline crack, a plating void, a slight dimensional deviation—can cause intermittent connections, field failures, and costly warranty claims. Yet as terminals become smaller and more complex, achieving the inspection precision needed to detect these defects becomes increasingly challenging.
Our High-Precision Terminal Vision Inspection Machine addresses this challenge head-on, delivering laboratory-grade measurement accuracy in a production-ready platform. With camera options ranging from 5MP to 20MP resolution, this system achieves comprehensive inspection accuracy down to 0.021mm—sufficient to detect the most subtle defects in even the smallest terminals and connectors.
Our inspection system is engineered to seamlessly integrate into your production line, providing continuous, real-time quality assurance. The process begins as terminal strips or connector arrays are fed through an adjustable material track into the inspection zone. Here, high-resolution top and side cameras capture detailed images from multiple angles, while synchronized lighting systems ensure optimal contrast and clarity. The system’s AI self-learning mode analyzes these images, comparing each component against a learned database of acceptable products to identify even the most subtle deviations.
Beyond defect detection, the machine performs comprehensive geometric measurements using a suite of 14 specialized tools capable of evaluating distances, angles, circles, and alignment features with exceptional precision. Integrated barcode and QR code recognition ensures part traceability and batch verification, while visual counting functions support inventory and packaging accuracy. The entire inspection cycle is completed in under 0.2 seconds per component, ensuring high throughput without compromising detail.
The system orchestrates a comprehensive inspection workflow through three dedicated stations:
1. Top Vision Inspection Station
An adjustable YZ-axis top camera with dedicated lighting captures detailed images of each terminal's upper surfaces, examining:
Contact area condition and plating quality
Terminal body geometry and dimensions
Surface defects including scratches, stains, and contamination
Feature presence (holes, slots, identification marks)
2. Side Vision Inspection Station
An independently adjustable YZ-axis side camera provides critical profile views, verifying:
Terminal height and bend angles
Side-surface condition
Coplanarity for surface-mount terminals
Crimp barrel condition (where applicable)
3. Feeding and Positioning System
Precision-ground adjustable tracks guide terminals through the inspection zone with consistent positioning, while pressure rollers ensure stable travel without vibration or skew.
Main Functions of Vision System:
1 - Self-Learning Mode for Good Product Judgment
This tool can learn good products through the image sensor and identify objects that differ from them as defective. It can also exclude the impact of individual variations among good products, making it very convenient.
2 - Geometric Dimension Measurement Tool
The geometric measurement tool includes 14 dedicated geometric measurement tools. These tools can be used to detect lines, circles, calculate distances or angles, and specify detected points, lines, or circles for distance or angle calculations.
3 - Barcode Recognition
Detects barcode information within the inspection range and reads its content. This tool can output the read data externally and also judge the acceptability of pre-registered content, such as dates, serial numbers, and other variable information. Additionally, it can perform separate inspections based on pre-set multiple comparison conditions.
4 - QR Code Recognition
Detects QR code information within the inspection range and reads its content. This tool can output the read data externally and also judge the acceptability of pre-registered content, such as dates, serial numbers, and other variable information. Additionally, it can perform separate inspections based on pre-set multiple comparison conditions.
5 - Defect Inspection (1)
Used to detect spots and stains on products, outputting the quantity (size) of defects and stains detected. In addition to spots and stains, it can also be used to detect unit area, volume, position, and other conditions.
5 - Defect Inspection (2)
After binarizing the image (black and white), it detects the area of "black" or "white". This tool is suitable for detecting stains or defects on monochrome surfaces based on area.
6 - Visual Counting
Detects objects of the same color as the extracted color and outputs their count. This tool is suitable for detection objects with unstable shapes or postures but consistent color and brightness.
