Description

Technical Field

[0001] The present invention provides a device for batch scanning of samples. Background Art

[0002] Ordinary whole box scanners or scanners can only identify cryotubes with prefabricated QR codes when scanning biological sample cryotubes. They cannot be used with cryotubes with custom labels and QR codes on the top, and can only be scanned manually. Existing whole box scanners have defects: they are mostly used to match prefabricated cryotubes of the same type, and cannot be used for more cost-effective custom-labeled cryotubes. Manual scanning of custom cryotubes has the disadvantages of low efficiency and slow scanning speed.

[0003] Most of the existing whole tray scanner equipment is designed for matching prefabricated cryotubes and standard cryoboxes. For example, Chinese patent CN207601811U discloses a cryotube batch scanning device, whose scanning head is fixed at the bottom of the scanner equipment box. The cryobox is placed on the positioning plate slot on the top of the scanning device for scanning. Only the QR code at the bottom of the cryotube can be identified, and there are also strict requirements on the size of the cryobox. Summary of the invention

[0004] In order to solve the above technical problems existing in the current scanning of a whole box of cryopreservation tubes, the present invention provides a device that can simultaneously support the scanning and identification of prefabricated two-dimensional code cryopreservation tubes and custom-labeled cryopreservation tubes.

[0005] The technical solution of the present invention:

[0006] A combined sample automatic warehousing scanning device includes a camera 2, which is installed in a scanner housing 7. A scanning port is provided on the lower surface of the scanner housing 7. The edge of the lower surface of the scanner housing 7 has a raised step structure, and is provided with a scanning positioning fixing plate 5. The scanning positioning fixing plate has a positioning groove hole. The outer contour of the scanning positioning fixing plate 5 is the same as the inner contour of the raised step structure on the edge of the lower surface of the scanner housing 7.

[0007] A scanning positioning fixing plate 5 is configured with a plurality of positioning groove hole specifications of different types.

[0008] A base 4 is provided, which is a cylindrical structure. The upper edge of the cylinder wall of the base 4 has a step structure that matches the step structure of the lower surface of the scanner housing 7 . The outer contour of the scanning positioning fixing plate 5 is the same as the inner contour of the cylinder wall of the base 4 .

[0009] The cylinder wall of the base 4 is provided with a sample inlet and outlet.

[0010] The scanning positioning fixing plate 5 has five specifications, and is stacked in the base 4 in sequence according to the size of the central positioning groove hole.

[0011] An indicator light 6 is installed on the outer surface of the scanner housing 7 , and the indicator light is connected to the camera 1 . A buckle structure inside the scanner housing 7 fixes the power cord plug and the network cable plug to connect with the camera 1 .

[0012] The scanning port on the lower surface of the scanner housing 7 is sealed with a transparent baffle 3 .

[0013] The scanning positioning fixing plate 5 is rectangular in shape as a whole, has chamfered corners at its four corners, and has an extended anti-mis-installation structure on one of its four sides.

[0014] A square positioning groove hole is provided in the center of the scanning positioning fixing plate 5 , and a step structure is provided on the hole wall of the positioning groove hole.

[0015] A protective silicone pad 1 is installed on the top of the scanner housing 7.

[0016] The beneficial effects of the present invention are:

[0017] When identifying prefabricated cryogenic tubes, the device is placed upside down, with the camera at the bottom of the device and the scanning direction pointing upward. By placing the cryogenic boxes in the grooves of the corresponding positioning plates on the top of the scanning device, cryogenic boxes of different types and sizes are accurately fixed at the center of the scanning camera, and the QR code on the bottom of the cryogenic tube is quickly, clearly and accurately captured to complete the identification.

[0018] When the device identifies cryogenic tubes with custom labels, the device base is installed. At this time, the camera is on the top of the device, and the scanning direction is downward. The cryogenic box is placed in the positioning slot in the base. Cryogenic boxes of different types and sizes can also be fixed in the center position of the scanning camera. The shooting, scanning and identification of the QR code on the top of the cryogenic tube can be completed accurately and quickly.

[0019] This device uses a new type of high-definition QR code scanning camera to simultaneously and accurately and quickly scan and identify QR codes of different types of cryopreservation tubes. It also uses a customized client program and network protocol to complete the settings of the scanning camera, scan, and transmit data for identification information, and provides a RESTful API interface for easy connection to the biological sample library system.
