Description

Technical Field

[0001] The present invention relates to the technical field of code scanning devices, and in particular to a code scanning method and a code scanning device. Background Art

[0002] Scanning code is a QR code and barcode recognition function that can recognize QR code and barcode information issued according to the prescribed code issuance rules and implement the services corresponding to the QR code and barcode; Bacterial culture is a technology that uses artificial methods to make bacteria grow and reproduce. Bacteria are widely distributed in nature, with large numbers and many types. They can benefit mankind, but they can also become the cause of disease. Most bacteria can be cultured artificially, that is, they are inoculated on culture media to make them grow and reproduce. The cultured bacteria are used for research, identification and application. Since the survival status and various conditions of bacteria at different periods need to be recorded during the bacterial culture process, and recording through paper materials is easy to lose or be damaged, it is most suitable to use a computer to edit and generate a barcode. The staff only needs to scan the barcode to view the growth status of different batches of bacteria; Psychrophilic microorganisms are microorganisms that survive in low-temperature environments. Their optimal growth temperature is -15℃ to +10℃, and the maximum growth temperature does not exceed 20℃. For example, cold shock proteins: they are expressed immediately when the temperature drops, participate in the transcription and folding of other proteins, and maintain metabolic activities at low temperatures. When it is necessary to understand the basic situation of psychrophilic microorganisms in test tube culture dishes, the barcode attached to the outside of the test tube is usually scanned to read the data; In the prior art, when scanning the barcode on the test tube, the test tube is usually manually grabbed for scanning. This method has low scanning efficiency. In addition, since low-temperature microorganisms are usually stored in a low-temperature environment, frost will appear on the surface of the test tube. The frost can easily block the barcode and affect the scanning effect. Manual defrosting further consumes a lot of time, further reducing the scanning efficiency.

[0003] To this end, a code scanning method and a code scanning device are proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a code scanning method and a code scanning device. By adjusting the position of the code scanning component above the tube rack, the code scanning component is moved to the top of any test tube, so that the code scanning component can quickly read the barcode on the test tube, thereby improving the code scanning efficiency. In the code scanning process, the test tube rotates and contacts the chamfered corner of the edge of the wiping rack to scrape off the frost on the outer wall of the test tube, so that the barcode on the test tube is in a clear state, which facilitates the scanner to quickly scan the code successfully and ensures the scanning effect.

The position of the barcode scanning component 3 is convenient to move to the top of any test tube 1051. The mechanical claw 305 can be moved to the top of the test tube 1051 by the hydraulic telescopic rod 302. When the mechanical claw 305 grabs the test tube 1051, the third motor 304 can drive the mechanical claw 305 to rotate slowly, so that the test tube 1051 can rotate slowly, and the barcode on the test tube 1051 can be slowly moved to the scanner 309, so that the scanning work can be completed quickly, manual scanning can be avoided, the scanning efficiency can be guaranteed, and the time cost can be reduced; During the code scanning process, the semicircular scanning plate 307 can be adapted to the side wall of the cylindrical test tube 1051. When the scanning plate 307 contacts the test tube 1051, the wiping frame 308 can fit tightly with the side wall of the test tube 1051. The chamfered edge of the wiping frame 308 can scrape off the frost on the outer wall of the test tube 1051, so that the barcode on the test tube 1051 is in a clear state, which is convenient for the scanner 309 to quickly scan the code successfully and ensure the code scanning effect. The connecting column 311 with a T-shaped cross-section can provide support for the spring 312, so the spring 312 can squeeze the connecting column 311, so that the connecting column 311 can be retracted into the movable hole 310, and a certain thrust can be provided to the scanning plate 307, so that the scanning plate 307 can fit tightly with the test tube 1051 during the contact with the test tube 1051, and the frost on the test tube 1051 can be scraped off. When scanning the code, the circulating water pump 404 continuously drives the condensate in the water storage tank 401 into the condenser 402, which can cool the placement tank 101 and ensure that the corresponding microorganisms in the test tube 1051 are in a suitable living environment during the code scanning process, and can avoid the inactivation of the microorganisms in the test tube 1051 due to long-term exposure to room temperature due to long code scanning time. After the circulating water pump 404 drives the water after heat exchange in the condenser 402 to flow back to the water storage tank 401, the cooling liquid in the condenser 402 When sprayed on the top of the water tank 401, since the diameter of the top of the condenser tube 402 gradually decreases, the pressure of the sprayed condensate is relatively large. After being sprayed, the condensate will contact the top of the water tank 401 and splash around, which can make the condensate after heat exchange evenly distributed and quickly cool down the condensate after heat exchange, thus ensuring the cooling effect. The thermal grease can improve the heat conduction efficiency, accelerate the cooling efficiency of the cold end of the semiconductor refrigeration sheet 405 to the water tank 401, and further ensure the cooling effect of the coolant in the water tank 401.
