The image-based assessment of different products is done with vision inspection machines. These machines are a boon to the manufacturing line. But some of us may not know how exactly this machine works.
First a quick look at the applications of these systems:
- It can be used in the testing and calibration
- It can be used for quality control purpose
- It can be used for sorting and counting
- It can be used for machine guidance and in data collection
- Process control in real-time is possible with the help of these systems
- It can also be used in the case of machine monitoring
Let us check the working of this machine!
The Visual Inspection Machine will have a camera or a set of cameras. These cameras will do automated inspection and analysis of materials. Usually, these machines are used in the assembly line of the company. The camera of the machine is programmed to perform certain specific functions. The camera will capture and analyse the image and will perform any of the below-mentioned functions:
- Checking the colour and size of the object
- Checking the dimensions of the object
- Finding any anomalies in the object like scratches, brunt parts, spots etc
- It will also help in finding out if there is any missing part
- These cameras are capable of reading printed characters
- They can also decode barcodes
Once the inspection of the material is completed then next there will be the generation of a signal. This signal will help in deciding what needs to be done next. That is whether the object has to be rejected or whether it has to be sent for further assessment etc.
The data that is collected using the Visual Inspection Machine is very useful in controlling the manufacturing activity. It is one of the best ways to provide quality products to the client.
Now go through the important components of this visual inspection system:
There are 4 main parts of a vision inspection system:
- The lenses
- A camera which is also called an image sensor
- The processor
- Method to communicate the output of the analysis
The lens that is used in the case of the vision inspection system will have a fixed focal length. The lens will capture the image. This image will be sent to the camera in the form of light. In order to get a good image, the emphasis has to be on the lighting, exposure time and aperture of the lens. The software tools will be applied after capturing the image.
There are different software tools that can be used in order to get information about the object. Some of the software tools are as follows:
- Pixel counting which helps in counting the light and dark pixels in the material
- Edge detection is used to determine the details about the edges of the object
- Gauging is used to find out the dimensions of the object
- Optical Character Recognition or OCR in the case of text reading
- Pattern recognition for finding patterns
- Barcode reader or data matrix for getting data in different barcodes
- Blob detection for finding blobs
- Colour analysis for quality assessment based on colour
Once the data is obtained using the software tools or the processor then this information is sent to the control system with the help of standard communication protocols.
So, this is the synopsis of the components of a vision inspection system and its working. When one approaches a Visual Inspection System Manufacturer, he will have to tell the details about the purpose of installing the machine in the manufacturing unit. Based on the details the manufacturer will decide on the type of processor to be used, the set of cameras that will be needed, the type of communication protocol that has to be used etc. This will decide the type of vision inspection system that the client will have to install in his company.
Your manufacturing unit needs a vision inspection system at the earliest:
Every company wants to increase productivity and reduce waste. Every company wants to give flawless quality products to the client. All this cannot be achieved with the help of manual inspection. For this, you have to choose an automated system.
