Description

Technical Field

[0001] The present invention relates to blood agar plates used in hospitals and medical laboratories, and particularly to a labeling barcode printing system dedicated to the side walls of blood agar plates. Background Art

[0002] Blood agar plates are widely used in hospitals and medical laboratories. After inoculating microorganisms on blood agar plates, it is often necessary to paste labels on the blood agar plates. The barcode information on the labels is the only identifier for recording patient information. Once an error occurs, all subsequent test and detection steps will also go wrong, directly threatening the health and safety of patients, causing serious consequences, and even leading to medical accidents of varying degrees.

[0003] The structure of blood agar plates is mostly disc-shaped, and its thickness (height) is about 13 mm. Most commercially available barcode printers support printing barcodes with a width generally greater than 15 mm, which cannot meet the printing requirements. Therefore, currently in hospitals and medical laboratories, labels are generally pasted on the bottom surface of blood agar plates. However, when blood agar plates are stacked together, it is not conducive to observing barcode information and automated scanning, and the barcode information is easily damaged during transportation.

[0004] Commercially available thermal barcode printers, such as the desktop thermal barcode printer of model Argox SG-2200, although they can print labels with a width of 10 mm, support RS232 communication, can print one-dimensional and two-dimensional barcodes, and are equipped with a label peeling mechanism (the function of separating the label from the backing paper); but this thermal barcode printer is only suitable for flat printing and is not applicable to blood agar plates with an arc-shaped side wall. Therefore, in order to adapt to the observation of barcode information and automated scanning, the current work of pasting labels on the side walls of blood agar plates is still completed manually. Manually pasting labels on the side walls of blood agar plates not only has low efficiency, but also has defects such as different degrees of wrinkling, warping, and uneven positions of the labels, and it is difficult to detect when the above defects occur. At the same time, during the process of manually pasting labels, it is difficult to control the aseptic environment, and cross-infection is likely to occur, resulting in biosafety.

[0054] The working process of the present invention is briefly described as follows:

[0055] Absorbing the label: The Y-direction conveyor belt 9.2 driven by the second motor 9.1 on the second bracket 9 moves the telescopic silicone vacuum suction cup 6 fixed on the third bracket 10 above the label baffle 4 at the label sending position through the guide rail 9.3. Then, the Z-direction conveyor belt 10.2 driven by the third motor 10.1 moves the three silicone vacuum suction cups 6 to the position opposite to the three vertical ridges 5. When the barcode printer 2 receives an instruction from the upper computer to print a barcode on the label and send out the label, the second motor 9.1 drives the Y-direction conveyor belt 9.2 to make the three silicone vacuum suction cups 6 lean against the surface of the label, and the single-chip microcomputer controls the solenoid valve 7 to open to generate negative pressure to absorb the label.

[0056] Label pasting: The Y-direction conveyor belt 9.2 driven by the second motor 9.1 moves the telescopic silicone vacuum suction cup 6 above the blood agar plate tray 8.1 carrying the blood agar plate through the guide rail 9.3; then, the Z-direction conveyor belt 10.2 moves the three silicone vacuum suction cups 6 adsorbed with labels to the label pasting position facing the side wall of the blood agar plate; finally, the Y-direction conveyor belt 9.2 moves the three silicone vacuum suction cups 6 towards the side wall direction of the blood agar plate, and causes the three silicone vacuum suction cups 6 to deform according to the arc surface of the side wall of the blood agar plate, and paste the label flat on the side wall of the blood agar plate. The single-chip microcomputer controls the solenoid valve 7 to close the negative pressure to release the label.

[0057] Label bar code scanning: The X-direction conveyor belt 8.3 driven by the first motor 8.2 drives the blood agar plate tray 8.1 to move to the position of the bar code scanner 1, so that the label on the side wall of the blood agar plate faces the scanning window for bar code scanning, and sends the bar code information to the upper computer; the upper computer judges whether there is an abnormality by reading the bar code information, such as incomplete label information, missing, wrinkled, etc. If there is an abnormality, an alarm message is sent.
