Robotic automation bottleneck
As you can see from the news in the media, the introduction of robots in the production process is accelerating. The government is also encouraging the introduction of robots through subsidies and grants. So, how is the automation of visual inspection using robots progressing? The following article is based on our [...].
Are large objects unsuitable for automatic visual inspection?
WE RECOMMEND THE PING-PONG METHOD, IN WHICH THE WORKPIECE IS MANUALLY SUPPLIED AND DISCHARGED BY HAND, AND ONLY THE INSPECTION PART IS PERFORMED BY A CAMERA OR PC. THE HANDLING IS DONE BY A PERSON, WHICH MEANS THAT LARGE WORKPIECES WITH LARGE VOLUME OR HEAVY WEIGHT CAN BE EASILY MOVED BY HAND....
Ping-pong method About multi-sided inspection
THE STANDARD SPECIFICATION OF THE PING-PONG METHOD IS 1-SIDED INSPECTION. IT DOES NOT SUPPORT MULTI-SIDED INSPECTION. NEVERTHELESS, THERE IS A NEED TO INSPECT MULTIPLE SIDES. IN THIS CASE, A POSSIBLE OPERATION METHOD WOULD BE TO CONTINUE INSPECTING ONLY SIDE A, THEN SWITCH THE TYPE AND INSPECT ONLY SIDE B [...].
Ping-pong method Specifications
Ping-pong method Flyer Specifications when a 300,000 pixel camera is used. When a high-resolution camera is used, a larger field of view can be obtained, so that larger workpieces can be handled. The following are the approximate field of view for the same pixel resolution [...].
Inspection of resin molded products Subsequently
RECENTLY, A CUSTOMER BROUGHT A PC, SOFTWARE, LIGHTING, AND A ROTATION STAGE WITH THEM TO INSPECT THE APPEARANCE OF A CYLINDRICAL PLASTIC MOLDED PRODUCT. THE AREA CAMERA WAS SET TO TAKE ABOUT 15 SEPARATE IMAGES/INSPECTIONS WHILE ROTATING THE SIDES OF THE [...]...
Inspection Accuracy ⑤.
The 300,000 pixel camera used for the ping-pong method can only handle small workpieces. In order to handle larger workpieces, 1.3, 2, and 5 megapixel cameras are used. For larger workpieces, we will use 1.3, 2, or 5 megapixel cameras.
Inspection accuracy ④.
Previously, we have simulated a case where a 300,000 pixel camera is used and the pixel resolution is 30μm. Now, let's consider the case where we want to detect a defect with a larger defect size. For example, if we want to detect a defect of 0.5 [mm square] [...].
Inspection accuracy ③.
In the case of a pixel resolution of 30μm (0.03mm), the field of view range can be calculated by applying the following formula. Pixel resolution = horizontal (X)/vertical (Y) field of view ÷ horizontal (X)/vertical (Y) resolution [...].
Inspection Accuracy (2)
As a case study, we will use the Basler acA640-750um (300,000 pixels) camera used for the ping pong system we are promoting. Basler acA640-750um The specifications of this camera [...].
Inspection Accuracy (1)
How large an object can be inspected? How small defects can be detected? We are often asked these questions. To summarize, if you are willing to spend the money and do not mind the inspection time, you can inspect objects of any size [...].
