From a grain of soy to a drop of soy sauce, now, this intangible cultural heritage that has gone through three thousand years has become an indispensable condiment on the table of every family. Food safety is an important issue that no food company can ignore, and soy sauce manufacturers are no exception. Even a humble bottle of soy sauce on the dining table is as small as its liquid level and whether the bottle cap is properly covered or not. In order to ensure the quality of each bottle of soy sauce to the utmost extent, soy sauce manufacturers will conduct various inspections to check the quality before the products leave the factory. Manual inspection is prone to misdetection and low efficiency, and has been gradually replaced by visual inspection equipment. The production date code on the soy sauce bottle is one of the important indicators for consumers to judge food safety. If there is no production date code on the soy sauce bottle, or the level of each bottle of soy sauce is different, even the bottle cap is not covered , Do you still dare to buy it? Surely you will feel that if you encounter fakes, the brand image of soy sauce will be greatly reduced. Therefore, before the soy sauce leaves the factory, it is very necessary to test the OCR, liquid level, and cap of the soy sauce bottle. 1. Install the OCR character visual inspection system on the soy sauce production line; 2. When the soy sauce bottle flows into the visual inspection station, the picture of the bottle taken by the machine vision sensor is triggered and sent to the system, and the system extracts, analyzes and sets the picture By comparison, we know whether the cap of the soy sauce bottle is tightened in place, whether the liquid level is within the standard tolerance range, and whether the coding is correct. 3. When it is detected that the cap of the soy sauce bottle is not tightened in place, the liquid level is not within the standard working tolerance range or the coding is wrong, the system will send a signal to the rejection device for rejection processing and alarm. Food safety is related to the national economy and people's livelihood, and food safety issues cannot be ignored.
