LED Inspection
A power bank manufacturer needs to inspect LEDs on the power bank. Before, many integrators prefer to use color mark sensors to check multiple predefined positions on the power bank one by one, to see whether there is LED blinking. Then, all the results needed to be integrated with a PLC. With the built-in vision tools and logic tools, the vision sensor is able to check the light intensity of all positions at one shot. Then all the check results of different positions are integrated automatically. Only one OK/NG signal will be output to indicate if the power bank is defective or not.

Liquid Level Inspection
A bottled mineral water manufacturer has recently introduced SC series vision sensors into its production lines for liquid level inspection. In the inspection spot, an area light panel is placed at back of the bottle, and the vision sensor is fixed in front of the bottle. The edge detection vision tool is used to measure the distance between the liquid level and the bottle cap. By virtue of its 60fps frame rate, the vision sensor needs only a back light panel that is slightly bigger than the bottle.
Printing Characters Presence Inspection
At the end of production, a thorough inspection is performed on the packaging of each product before they are finally packed in batch. Among many inspection items, the inspection of production date is a key item. After testing, it is confirmed that the surface with printing characters has an obvious contrast difference comparing to that without printing characters. The SC series vision sensor provides contrast measurement function, which realizes the presence/absence detection of the production date in the simplest way. In the future, we believe that more new technologies, like 5G and AI, will be integrated to machine vision products, including vision sensor and other smart cameras. The vision sensor will become smaller, more powerful and easier to use.
