Description

Technical Field

[0001] This invention relates to the field of sample storage technology, and in particular to a method for scanning traceability codes for cryopreservation tubes. Background Technology

[0002] As the core container for storing biological samples, cryovials require traceability code management to ensure sample integrity, traceability, and safety.

[0003] Cryopreservation tubes are typically designed in a conical or cylindrical shape, with a QR code on the bottom and a 1D barcode on the side. In practical applications, scanning the side of a cylindrical tube usually requires actively rotating the tube to align the label with the scanning mechanism, a rather cumbersome process. Furthermore, the cylindrical shape makes it difficult for a single camera to simultaneously capture both the bottom QR code and the side 1D barcode. Traditional methods require rotation or multiple cameras to achieve multi-angle recognition, resulting in high equipment complexity, high cost, and low recognition efficiency.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0042] Example 1

[0043] Reference Figs. 1-4 This is the first embodiment of the present invention, which provides a method for scanning the traceability code of cryopreservation tubes, comprising:

[0044] S1. Define the target scanning range area;

[0045] S2. Set a 360-degree optical path reflection structure for the target scanning area;

[0046] S3. Set the scanning mechanism to scan the target scanning area and receive the reflected light path image / screen from S2.

[0047] Preferably, the cryopreservation tube / sample tube is placed within the field of view of the reflection mechanism and the barcode scanning mechanism. The reflection mechanism can reflect and display the label on the cryopreservation tube, and the barcode scanning mechanism can provide 360-degree full coverage of the label displayed by the reflection mechanism and / or the label on the cryopreservation tube.

[0048] Furthermore, step S2 further comprises at least two reflectors arranged in a V-shape.

[0049] Ideally, the angle between the two mirrors should be 120 degrees.

[0050] Preferably, the two reflectors are arranged in a V-shape, and the cryopreservation tube is placed in the middle of the two reflectors, at a certain distance from the two reflectors.

[0051] It should be noted that by using mirrors arranged at specific angles to reflect the image of the one-dimensional barcode on the side of the cryopreservation tube into the camera's field of view in 360 degrees, the one-dimensional barcode on the side of the cryopreservation tube can be obtained in the scanning mechanism's field of view regardless of the angle of the cryopreservation tube.

[0052] It should be noted that when the label on the cryopreservation tube is facing the scanning mechanism, the scanning mechanism can scan the label. When the label on the cryopreservation tube is not facing the scanning mechanism, the two reflectors will completely refract and reflect the label on the cryopreservation tube, and the scanning mechanism will scan and identify the label on the two reflectors.

[0053] Furthermore, in step S3, the scanning mechanism is located on the side opposite to the reflector;

[0054] In step S2, the reflector is configured with the following parameters: reflector angle θ, reflector length w, distance d1 between the cryopreservation tube and the scanning mechanism, distance d2 between the far end of the reflector and the scanning mechanism, cryopreservation tube size D, scanning mechanism parameter FOV, distance l1 between the near end of the reflector and the center of the cryopreservation tube, and angle θ between the near end of the reflector and the scanning mechanism. ' The distance from the near-end mirror of the reflector to the barcode scanning mechanism is l2:

[0055] It should be noted that θ is the angle between a reflector and the central axis of the sample tube, and the angle between the near-end mirror distance of the reflector and the scanning mechanism is θ. ' θ ' It is also based on the central axis of the sample tube.

[0056] θ ' The calculation formula is

[0057]

[0058] It should be noted that if θ ' If it's too small, it will obstruct the scanning mechanism; if θ ' If it is too large, it will be beyond the visibility of the scanning agency.

[0059] Furthermore, in step 2:

[0060] The angle calculation parameters for l1 are:

[0061] The angle calculation parameters for l2 are:

[0062]

[0063] Therefore, l1, l2, and d1 must all be within the focal length to achieve a 360-degree full visual coverage of the cryopreservation tube's side. Further, step S3 includes:

[0064] S31. If there is a label on the end of the cryopreservation tube near the reflective mechanism, the two reflectors can refract and fully display the label on the cryopreservation tube.

[0065] S32. When the cryopreservation tube is placed within the field of view of the reflection mechanism and the scanning mechanism, the side scanning mechanism can simultaneously scan the two reflection mirrors and the cryopreservation tube near the scanning mechanism, achieving 360-degree full coverage of the cryopreservation tube.

[0066] It should be noted that, since the location of the label on the side of the sample tube is unknown when it is placed, if the label is close to the reflector, it will be reflected and displayed by the reflector. If the label is close to the scanning mechanism, the scanning mechanism will directly scan and identify it, thereby achieving full 360-degree visual coverage of the side of the cryopreservation tube.

[0067] In summary, the present invention can provide a 360-degree field of view of the side of the cryovial using two V-shaped reflectors, eliminating the need for manual rotation of the cryovial. The device has a compact overall structure and is suitable for integration into various stages of an automated cryovial management system, including processes such as warehousing, outbound, and quality inspection.

[0068] Example 2

[0069] refer to Figs. 1-4 In the second embodiment of the present invention, based on embodiment 1, the method for scanning the traceability code of the cryopreservation tube further includes: a first scanning device 1, which can perform 360-degree scanning and identification on the periphery of the sample tube.

[0070] Furthermore, the first scanning device 1 includes a reflective mechanism 11, a support body 12, and a scanning mechanism 13; the reflective mechanism and the scanning mechanism are disposed on the support body, and the scanning mechanism is disposed on the opposite side of the reflective mechanism. The cryopreservation tube is disposed between the reflective mechanism and the scanning mechanism. The reflective mechanism can refract and display the label on the periphery of the cryopreservation tube, and the scanning mechanism can scan the label displayed by the reflective mechanism or the label on the cryopreservation tube.

[0071] Preferably, the reflective mechanism 11 and the scanning mechanism 13 can be supported on the support body 12, and the cryopreservation tube is placed between the reflective mechanism 11 and the scanning mechanism 13, so that the cryopreservation tube label is refracted and displayed by the reflective mechanism 11.

[0072] Furthermore, the reflection mechanism 11 includes two reflectors 111 connected in a V-shape at an angle of 120 degrees, and the cryopreservation tube is disposed between the two reflectors.

[0073] Furthermore, the support body 12 is provided with a cryopreservation tube groove 14, in which cryopreservation tubes can be placed.

[0074] Preferably, by placing the cryotube into the cryotube slot 14, without rotating the cryotube, the label on the cryotube is reflected by two reflective mirrors 111, and a scanning mechanism is used to scan the two reflective mirrors 111 and the label on the cryotube.

[0075] In summary, the present invention can provide a 360-degree field of view of the side of the cryovial using two V-shaped reflectors, eliminating the need for manual rotation of the cryovial. The device has a compact overall structure and is suitable for integration into various stages of an automated cryovial management system, including processes such as warehousing, outbound, and quality inspection.

[0076] Example 3

[0077] This invention is the third embodiment, and the method for scanning the traceability code of cryopreservation tubes includes:

[0078] S1. Define the target scanning range area;

[0079] S2. Set a 360-degree optical path reflection structure for the target scanning area;

[0080] S3. Set the scanning mechanism to scan the target scanning area and receive the reflected light path image / screen from S2.

[0081] Furthermore, step S2 further comprises at least two reflectors arranged in a V-shape at an angle of 120 degrees.

[0082] Furthermore, it also includes a second scanning device, which can cover the label at the bottom of the sample tube and the labels on the sides 360 degrees.

[0083] Furthermore, the second scanning device includes a reflective mechanism, a support body, a scanning mechanism, and a second reflector; the support body is provided with a reflective mechanism, and a second reflector is provided on the opposite side of the reflective mechanism; a cryopreservation tube is provided between the reflective mechanism and the second reflector; a scanning mechanism is provided below the cryopreservation tube; the scanning mechanism can scan the label on the bottom of the cryopreservation tube and the label on the second reflector.

[0084] The support body below the cryopreservation tube can be made of transparent material, which can support the cryopreservation tube while allowing the scanning mechanism at the bottom to scan and recognize the QR code on the bottom of the cryopreservation tube and the 1D code on the second reflective element.

[0085] Preferably, by placing the scanning mechanism below the cryopreservation tube, and by allowing the scanning mechanism to reflect the barcode through a second reflector, a single scanning mechanism can scan and identify the QR code on the bottom and the 1D barcode on the side of the sample tube.

[0086] Furthermore, the second reflector is tilted, and the second reflector can simultaneously refract and reflect the mechanism and / or the label on the sample tube.

[0087] Furthermore, the second reflector includes a third plane mirror, which is disposed on one side of the sample tube and at the end away from the reflective mechanism. The third plane mirror is in the shape of a "\".

[0088] Preferably, the third plane mirror is tilted with its upper end tilting towards the cryopreservation tube and its lower end tilting away from the cryopreservation tube, so that the scanning mechanism at the bottom can scan the label reflected on the third plane mirror.

[0089] Since it is unclear where the label is on the side of the sample tube when it is placed, if the label is close to the side of the reflector, it will be refracted and displayed by the reflector. If the label is close to the side of the third plane mirror, it will be refracted and displayed by the third plane mirror.

[0090] When in use, if the cryopreservation tube has a label at the end near the two reflectors, the label will be refracted and displayed on the two reflectors and reflected by the third plane mirror, so that the scanning mechanism at the bottom can simultaneously scan and recognize the QR code on the bottom of the cryopreservation tube and the 1D code on the third plane mirror.

[0091] If the cryopreservation tube does not have a label at the end near the two reflectors, the label will be on the side near the third plane mirror. In this case, the label on the cryopreservation tube can be reflected onto the third plane mirror. Since the third plane mirror is tilted, the scanning mechanism at the bottom can scan the label on the third plane mirror and the label on the side of the cryopreservation tube at the same time.

[0092] Furthermore, the label on the side of the sample tube furthest from the third plane mirror can be reflected and displayed in the two mirrors; the label on the side of the sample tube furthest from the two mirrors can be reflected and displayed on the third plane mirror; the label in the mirror or the label on the sample tube closest to the third plane mirror can be reflected and displayed on the third plane mirror.

[0093] The solution in this embodiment enables the cryopreservation tube to be scanned and identified regardless of the location of the label. Furthermore, the bottom scanning mechanism in this embodiment can simultaneously scan the labels on the bottom and sides of the cryopreservation tube, achieving 360-degree full coverage of the bottom and sides of the cryopreservation tube.

[0094] In summary, the present invention can cover the bottom and sides of the cryopreservation tube 360 ​​degrees with the second scanning device, and can simultaneously acquire the bottom QR code and side 1D barcode information in a single image, significantly shortening the overall scanning time.
