Capacitance Vision Systems For Quality Inspection

Capacitance detection equipment is mainly glass plate detection equipment and dividing plate detection equipment to complete together.

The main functions of the equipment: (1) Glass disk detection equipment is mainly used to detect whether the capacitor has a bulge, the upper surface and the lower surface, the size of the product, etc. (2) Indexing plate detection equipment is mainly used to detect capacitor appearance, positive and negative poles, hidden line level, etc. ③ Accuracy of detection: ±0.02mm. ④ Detection speed: up to 200 per minute.

I. Introduction of capacitance detection equipment

Traditional product and quantity inspection generally rely on human eyes, but a long time of visual damage to workers' eyes and detection is easy to make mistakes, more important is high labor cost, low efficiency. If the automatic inspection scheme of mechanical vision is adopted, it can easily realize the continuous inspection of large quantities, long time and high precision. The outline and appearance judgment of electronic components (capacitor housing) is a must-do test item before the next process. The current method of manual detection has the disadvantages of slow speed, heavy workload and high error rate. The common defects of electronic components (capacitor housing) are: defects, surface scratches, cracks, obvious stains, surface foreign bodies, appearance deformation, various folds, bubbles and burrs in the epoxy part, stitches of different lengths, etc.

Two, the characteristics of capacitance detection equipment:

1. Complete inspection under high production speed;

2. High-speed camera and processing technology can quickly detect, classify, display and eliminate defects;

3, excellent optical equipment for scarce defect detection, even low contrast defects;

4. Intelligent classification software: defects are classified into various directories according to the source;

5, simple and convenient operation, without in-depth study can use defect detection system;

6. Accurate, real-time and reliable information;

7. Automatically generate erp reports.

Three, the function of capacitance detection equipment

1. Complete new product customization function, it is very convenient to realize the equipment's detection of new products through customization;

2, the equipment will automatically judge, and give the test result and instruction, the operator will take down the tested product, or the system will automatically eliminate;

3. It is convenient to modify the previously saved detection template;

4, high detection accuracy, good stability, low detection and false detection rate;

5, based on pc visual detection software, powerful, easy to operate. Good cost performance, versatility and applicability.

6, human-machine interaction is good, no manual operation, easy to use, simple operation;

7, can be different workpiece specifications parameters, allowed deviation Settings, and saved in the form of a file in the computer. When detecting different artifacts, just load the corresponding file.

Iv. Detection method of capacitance detection equipment

When the products to be inspected arrive at the assembly line station, the drawing system will take pictures, collect the pictures, the software will automatically judge, and give the test result in the software interface, sound and light indicator and other output units. The subsequent automatic system will eliminate the defective products according to the test result. The system has the function of data statistics, can automatically save the pictures of defective products, can save the previous Settings and automatic calls, can change, add, modify the product model, replacement of new products only need to change the Settings. This method is not affected by the external environment, not affected by the operator itself, good unity, high stability, strong reliability, to improve the production efficiency and product quality of the enterprise is very helpful.

5. Detection items of capacitance detection equipment

1. Detection content: detection of defects, surface scratches, cracks, obvious stains, surface foreign bodies, appearance deformation, various folds, bubbles burr in epoxy parts, length of stitches and other defects;

2, detection speed: the whole machine detection speed ≥60 pieces/min;

3, detection mode: the operator puts the product into the detection station, the system's camera automatically determines whether the product is correct, and automatically classifies and selects qualified products and unqualified products;

4. Omission and error rate: error rate (unqualified products wrongly judged as unqualified products) ≦3%, omission rate (defects, unqualified materials) =0;

5. Feeding mode: vibrating disk or docking with other equipment for feeding, the feeding mode can be customized according to specific requirements;

6, take the picture mode: static and mobile photography.
