Machine vision inspection scheme of round hardware accessories

1. Test content and requirements

Detection of workpiece area:

Testing of cylindrical samples with overall height 4*2.5mm

Test contents:

1: The bottom edge of the detection of incision, hole, diameter

2: Side detection of total height

3: Top detection diameter, whether there is a hole

Note: The above test items, all need to be clearly visible under the image to detect

Detection efficiency: 200-400 pieces per minute (according to the sample feeding speed).

Division of work: subdivide the detection steps according to the detection content.

Two: equipment composition and main institutions

Overall composition: Size: 900*800*1850 mm

Model :HL-301

1: Visual detection software

2: Industrial computers

3: Monitor 19 inches

4: Industrial camera: 3 sets, bottom and top detection diameter, hole, edge incision. Side detection height

5: Industrial lenses: 3 sets of FA industrial cameras

6: Professional glass plate

7: solenoid valve

8: reducer

9: Vibration cabinet

10: Feeding equipment (vibration disk, direct vibration, controller).
