Automatic feeding is to arrange the workpiece or blank in a direction and automatically send it to the designated working position of other stations of the automatic detection equipment according to a certain time interval of the working cycle of the machine tool.

Automatic feeding device is an indispensable auxiliary device in automatic equipment. In the field of machinery, the handling of materials, loading and unloading of machine tools and assembly of the whole machine are relatively weak links. For medium and small parts, the loading and unloading time accounts for about 20-70% of the auxiliary time, and for large parts, the loading and unloading time accounts for about 50-70% of the auxiliary time.

There are many common feeding methods for automatic detection equipment, including the following:

1. Vibrating plate loading

2. Hoist loading

3. Rotating material tray loading

4. Robot feeding

5. Feeding of conveyor belt

6. Bin type feeding
