OCR Vision Character Visual Inspection System For Industrial And Packing

OCR Machine Vision Character Visual Inspection System For Industrial And Packing

System features

The functional characteristics of the OCR machine vision character detection system are to perform image recognition and detection on the appearance, defect, presence, position, etc. of the characters printed on the tested object, and output the detection results.

• Detect barcode character printing defects, such as dirt, reprint, black spots, etc.;
• Detect the right or wrong of barcode characters;
• Detect the integrity of barcode characters, whether there is missing printing or less printing, etc.;
• Dynamic static detection.

Inspection principle

The character detection system developed by KEYE TECH based on machine vision image processing technology has the characteristics of high precision, high speed and multi-sample. The main modules of the system are: image processing module and control module. According to user requirements, the sample moves to the detection position, triggers the camera and outputs detection signals to the vision system in time to complete the detection function.

After the product is in place, the system recognizes the character information; matches the recognized information with the font information, and compares it with the set characters; if the information is consistent, the system outputs 0K signal, and when the information is inconsistent, the system outputs NG signal.

Application scenarios:

1. Application Scenario: Character Detection System Application Scenario;
2. Packaging Character/Label Visual Inspection;
3. Bottle cap character visual inspection;
4. Phone case character detection;
5. Characters and barcodes on semiconductor wafers;
6. Electronic capacitance screen printing inspection, visual inspection of electronic components;
7. Visual inspection of card characters, visual inspection of surface character recognition.

OCR visual character detection advantages

• Accuracy: avoid misjudgment and missed detection caused by subjective consciousness, environmental restrictions and other factors in the process of manual detection and identification, and the detection accuracy is guaranteed;
• Productivity: ocr vision system equipment can work for a long time, with fast recognition speed, which can effectively improve production efficiency;
• Multi-function: ocr visual character recognition can identify barcodes, numbers, characters with multi-function detection function, one machine is multi-purpose
• Systematic: The test results are saved by themselves and displayed in real time, which is convenient for later information query, invocation, statistics, etc.;
• Low cost: reduce labor cost input, high product testing accuracy, quality assurance, and low probability of recall.
