Noise Suppression 3
By using an oscilloscope and looking at what kind of waveform it is, the cause of the noise can be identified. Waveform of the camera Reference video If you see a waveform like 60 Hz AC, it may be due to the operating inverter or servo motor [...].
Noise Suppression 2
Our company originally started out mainly as a developer of image processing software. As we accumulated expertise in the field, we now provide support for visual inspection equipment as well as for reliable operation. For this reason, we have developed software, electrical controls, mechanical systems [...].
Noise Suppression 1
The software may suddenly shut down, the camera may shut down at an unbelievable timing, or the operation may become unstable. This may be due to electrical noise (extra signals). For example, if the workpiece is large [...].
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] [...].
