The working principle and main components of CCD visual inspection machine

CCD visual inspection machine is machine vision inspection machine, using industrial camera to take pictures, analyze the image, get the desired effect, the main components are industrial camera, lens, light source, industrial computer, servo motor, motion control part, vibration plate and so on.

A, CCD visual detection machine working principle

The main working principle of CCD visual detection machine is to take pictures with industrial cameras, obtain image analysis image, identify NG, OK products, and remove defective products by the solenoid valve or cylinder, using vibration plate feeding, the whole process of continuous detection, continuous removal of defective products.

Two, the main components of CCD visual detection machine:

1. Industrial cameras

Generally choose imported famous brands, stable and reliable, long use;

2. Lens

According to the needs of the project selection, it is best to choose mature brands, can not distort badly, affect the detection;

3. Light Source

Generally choose LED light source, luminous stability does not flicker, in order to ensure the detection accuracy, pay attention to the heat dissipation of the light source, can extend the service life;

4. Industrial computer

General configuration is relatively high, in order to quickly process complex algorithms;

5. Turn the motor

The best use of imported servo motor, small jitter, smooth speed, easy intelligent control;

6. Motion control

PLC+ motion control card, give play to their advantages, let the whole system run smoothly;

7, vibration disk

Generally choose high speed discharge type, because the visual detection part of the detection speed is millisecond level.

Three, why choose to use CCD visual detection machine?

If the use of manual screening of product defects, there will be artificial elastic fatigue and human detection errors, so it will lead to product screening errors and selection is not clean, customers may cause complaints and huge loss compensation, damaging the image of the company. At the same time, the detection speed of CCD visual detection machine is very fast. For the micro precision screws and nuts on the mobile phone, the detection speed can reach 1200pcs/min.

CCD visual detection machine can reduce manpower, save labor costs, and greatly reduce human detection errors, and then improve work efficiency, improve product delivery quality, enhance product competitiveness. If the CCD visual detection machine is further used in the production control process, in the production line at the same time of product quality monitoring, not only can reduce the waste of raw materials, but also can further effectively control the production time.
