"Inspection Equipment for NdFeB Workpiece Dimensions in the Magnetic Material Sector"

Advancements in NdFeB Permanent Magnet Quality Inspection

The demand for NdFeB permanent magnet products has been consistently increasing, leading to a significant rise in production output. However, manufacturers face a critical challenge: outdated quality inspection methods that result in low detection efficiency. This mismatch between rapid production rates and inadequate inspection processes has created a bottleneck in the industry's growth. Transitioning to automated rapid testing equipment can replace traditional manual sampling methods, significantly improving the rate of compliant products and enhancing competitive positioning in the market.

Overview of the Inspection Device

The NdFeB workpiece size detection system employs advanced optical control technology. Utilizing non-contact optical measurement techniques, this equipment can swiftly assess the dimensions, data accuracy, and surface quality of various permanent magnet products, while also enabling automatic sorting. The design features no wear components, resulting in minimal maintenance costs over time.

System Components

The inspection system is composed of several key elements, including:

• Industrial Computer: Central to data processing and control.
• Digital Acquisition Card: Transmits digital signals from the testing unit to the industrial computer.
• Motion Controller: Receives signals from the industrial computer to manage the material transfer and sorting units.
• Testing Unit: Conducts the actual measurements and assessments.
• Material Transfer Unit: Automatically feeds materials to the testing station.
• Sorting Unit: Classifies products based on quality standards set by the user.

The proximity sensor triggers the detection process, while the sorting unit organizes products according to defined eligibility criteria, ensuring efficient output.

Specifications

The inspection system boasts impressive capabilities, including:

1. Detection Efficiency: Capable of inspecting 200 to 400 pieces per minute, depending on product dimensions and shapes.
2. Test Items: Evaluates various size metrics and surface defects on both sides of the products.
3. Product Shapes: Accommodates diverse forms such as square rings, square pieces, circular rings, wafers, and VCM magnetic pieces.
4. Size Detection Range: Effective for products ranging from 2mm to 25mm in size, with thickness not exceeding 3mm.
5. Automatic Functions: Includes features for automatic discharge, cutting, and sorting based on user-defined criteria.
6. Data Management: Capable of storing inspection data and generating reports for quality tracking and control.

Benefits of the System

1. Enhanced Product Quality: By moving away from sampling inspections, the system allows for comprehensive size checks, significantly reducing the occurrence of non-compliant products. Additionally, the implementation of computer vision technology ensures objective evaluation of appearance defects, thereby improving the overall quality of products delivered to customers.

2. Improved Market Competitiveness: The shift from manual inspection methods to automated systems positions manufacturers more favorably within the NdFeB permanent magnet industry. Enhanced quality assurance translates to better market standing and increased order acquisition opportunities.

Potential Applications

The system can be customized to test a variety of magnetic materials, accommodating different shapes and specifications based on client needs.

After-Sales Support

The inspection device includes cloud functionality, allowing connection to a remote service platform for diagnostics and software updates. This feature enables engineers to perform remote maintenance, reducing costs associated with warranty repairs and minimizing downtime.

Transaction Options

Customers have flexible options for acquiring the inspection equipment, including outright purchase, leasing, or piece-rate service agreements.

In summary, the integration of automated inspection equipment for NdFeB permanent magnets not only addresses existing quality inspection challenges but also positions manufacturers for future growth and enhanced market presence.
