In some application scenarios that require high space, the advantages of integrated visual sensor products are very prominent. Meiji Sensing has solved many visual inspection problems for customers with this visual sensor, which is only the size of a Bluetooth headphone case. In this issue, Xiao Ming will share with you~

Button quantity detection

Testing requirements:

There are 5 buttons on the PCB board, and visual inspection is needed to filter out defective products with missing buttons

Solution:

Based on the position of the buttons, select the VSD10 series visual sensor and use pattern presence and counting tools to determine the presence and angle deviation

detection effect

OK

All five buttons are complete, judged as OK

NG

Manually cover one of the button positions, only 4 buttons detected, judged as NG

NG

Manually covering the position of another button, only 4 buttons were detected, judged as NG

Check if the pin is installed properly

Testing requirements:

Check if the PIN pin on the PCB board is properly inserted

Solution:

Based on the image features on both sides of the PIN needle, select the visual sensor VSD10 series and use the tool to determine whether the pattern is present or not

detection effect

OK

Pin inserted in place, pattern displayed normally, judged OK

NG

Pin skewed, pattern display abnormal, judged as NG

NG

Covering one of the pins, abnormal pattern display, judged as NG
