Automatic Labeling Machine Test Tube Selection Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic labeling machines for vacuum test tubes require manual selection of test tubes based on color, leading to potential errors in detection results due to human mistakes.
Innovation Solution
An automatic labeling machine with a controller and prompting apparatus that determines the type and color of the test tube, using a storage apparatus to correlate types with cover colors, and outputs prompting information via color, voice, or image to guide the operator in selecting the correct test tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual selection of test tube type is implemented, then the labeling machine can be operated, but selection errors occur leading to wrong detection results
Solution Approach 1:
The system provides visual feedback through a prompting apparatus that displays the required test tube type (e.g., red cover for serum separation, green cover for plasma separation) before the operator inserts the test tube. This feedback loop allows the operator to verify the correct tube type is selected, eliminating selection errors while maintaining manual operation.
Solution Approach 2:
A controller acts as an intermediary between the detection system and the labeling apparatus. The controller receives detection information, determines the appropriate test tube type, and transmits this information to the prompting apparatus, which then guides the operator. This intermediary process eliminates direct manual selection errors by providing systematic guidance.
2Adaptability or versatility
If multiple categories of vacuum test tubes are used, then comprehensive blood testing is enabled, but manual checking and selection increases error probability
Solution Approach 1:
The prompting apparatus provides clear visual feedback indicating which specific test tube category is required based on the detection information. For example, it displays 'red cover' for serum separation or 'green cover' for plasma separation, allowing the operator to correctly select among multiple tube categories without confusion or errors.
Solution Approach 2:
The system utilizes color information from the test tube covers (red, green, other colors) as key identifiers. The controller processes the detection information to determine the required cover color and transmits this to the prompting apparatus, which visually indicates the correct color to the operator, enabling accurate selection among multiple tube categories.
3Ease of operation
If operator determines test tube type manually, then flexibility in operation is maintained, but mistakes lead to wrong detection results
Solution Approach 1:
The system maintains operator control while providing real-time feedback through the prompting apparatus that displays the required test tube type. The operator decides when to insert the tube but is guided by the visual information, combining manual operation flexibility with error prevention through systematic feedback.
Solution Approach 2:
The controller determines the required test tube type in advance based on the detection information before the operator performs the insertion action. This preliminary determination and communication to the prompting apparatus ensures the operator has the correct information before making the selection, preventing mistakes while maintaining operational flexibility.

AI summary
Disclosed are an automatic labeling machine and an automatic labeling machine control method. The automatic labeling machine is used for adhering an identification label on a surface of a test tube. The automatic labeling machine comprises: a tube insertion port (80) used for inserting a test tube; a controller (4) used for determining the type of test tube to be inserted; and a prompting apparatus (3) connected to the controller (4) and used for outputting prompting information corresponding to the type of the test tube to be inserted. The problem of automatic labeling machines easily causing a test tube selection error in the prior art is solved.
