[0035] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0037] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0038] See also Figures 1 to 3The embodiment of the present application provides a biological sample scanning device 100, including a grabbing mechanism 10, a rotating drive mechanism 20, a horizontal drive mechanism 30, a lifting drive mechanism 40 and an image acquisition device 50; the grabbing mechanism 10 includes at least two grabbing components 11, each grabbing component 11 is arranged at intervals along a first horizontal direction X, and is used to grab a sample tube 300; the rotating drive mechanism 20 is used to drive all the grabbing components 11 to rotate around their respective vertical axes, the horizontal drive mechanism 30 is at least used to drive each grabbing component 11 to move along a second horizontal direction Y, the lifting drive mechanism 40 is at least used to drive each grabbing component 11 to move up and down, and the image acquisition device 50 is used to capture an image of the information identification code of the sample tube 300 grabbed by the grabbing component 11; wherein the first horizontal direction X intersects with the second horizontal direction Y.

[0039] When in use, the horizontal driving mechanism 30 can drive all the grasping components 11 to move along the second horizontal direction Y to the top of the corresponding sample tube 300 to be grasped, and the lifting driving mechanism 40 drives all the grasping components 11 to descend to the first preset height, and the grasping components 11 can grasp the sample tube 300 at the first preset height; after the grasping components 11 grasp the sample tube 300, the lifting driving mechanism 40 can drive all the grasping components 11 to rise to the second preset height; after the grasping components 11 drive the sample tube 300 to rise to the second preset height, the rotating driving mechanism 20 can drive each grasping component 11 to rotate around its own vertical axis, and the rotation of the grasping component 11 drives the grasped sample tube 300 to rotate, and the image acquisition device 50 can capture images of the information identification code of the grasping tube 300 grasped by the grasping component 11 when it rotates; when the image acquisition is completed, the rotating driving mechanism 20 stops working, the lifting driving mechanism 40 drives all the grasping components 11 to descend to the first preset height, and the grasping components 11 release the sample tube 300.

[0040] By adopting the above technical solution, the grabbing mechanism 10 can grab multiple sample tubes 300 through multiple grabbing parts 11, and the image acquisition device 50 can capture images of the information identification codes of all sample tubes 300 captured by the grabbing parts 11, so that the information identification code images of multiple sample tubes 300 can be quickly obtained, which greatly speeds up the speed of collecting the information identification codes on the sample tubes 300 and effectively shortens the collection time. In addition, the rotating drive mechanism 20 drives the sample tube 300 to rotate relative to the image acquisition device 50, which can ensure that the image of the information identification code can be collected regardless of where the information identification code is pasted on the side wall of the sample tube 300, which greatly reduces the requirements for the pasting position of the information identification code and also reduces the requirements for the orientation of the information identification code when the sample tube 300 is loaded in the sample box 200.

[0041] Furthermore, the biological sample scanning device 100 provided in this embodiment can capture images of information identification codes of sample tubes 300 placed in existing sample boxes 200, without placing the sample tubes 300 in special sample boxes, and has low requirements for the sample boxes.

[0042] It should be noted that the information identification code can be a QR code, a barcode, etc., and the specific form of the information identification code is not limited here.

[0043] In another embodiment, the horizontal driving mechanism 30 can also be used to drive all the grabbing components 11 to move along the first horizontal direction X. Usually, a plurality of accommodating holes arranged along a certain pattern are provided in the sample box 200, and each accommodating hole can accommodate a sample tube 300. When the number of the grabbing components 11 arranged along the first horizontal direction X is less than the number of the sample tubes 300 arranged in this direction, the horizontal driving mechanism 30 is set to drive all the grabbing components 11 to move along the first horizontal direction X, and the grabbing mechanism 10 can grab all the sample tubes 300 arranged along the first horizontal direction X. Of course, in a specific implementation, when the horizontal driving mechanism 30 is set not to drive all the grabbing components 11 to move along the first horizontal direction X, the sample box 200 can be manually pushed to move along the first horizontal direction X, so that all the sample tubes 300 arranged along the first horizontal direction X can be finally grabbed.

[0044] In one embodiment, the number of the grabbing components 11 is set to at least ten. The specification of the sample box 200 is usually 10x10 or 12x10. By setting the number of the grabbing components 11 to at least ten, the grabbing mechanism 10 can simultaneously grab all sample tubes (i.e., ten sample tubes) arranged along the first horizontal direction X in the sample box 200, without the need to set a horizontal driving mechanism 30 to drive the grabbing components 11 to move along the first horizontal direction X, and without the need to manually push the sample box 200 to move along the first horizontal direction X.

[0045] In one embodiment, the grabbing member 11 is configured to grab the sample tube 300 from above the sample tube 300. A plurality of sample tubes 300 are usually placed in the sample box 200, and the grabbing mechanism 10 will grab some of the sample tubes 300 in one grabbing operation. By arranging to grab the sample tube 300 from above the sample tube 300, when performing the grabbing operation, the interference of the sample tube 300 not being grabbed in the grabbing process with the grabbing member 11 can be easily avoided. In addition, grabbing the sample tube 300 from above the sample tube 300 can complete the image acquisition of the information identification code on the sample tube without changing the existing sample box structure and the sample tube structure. Of course, in other embodiments, it is also possible for the grabbing member 11 to be configured to grab the sample tube 300 from the side of the sample tube 300.

[0046] It should be noted that the limitations of directional words such as top, bottom, up, and down in this application are for ease of understanding. The description made when the biological sample scanning device 100 is in use is only used to reflect the relative position relationship between the structures. When the biological sample scanning device 100 is in other postures, the directional words in this application should be understood after switching to the use state.

[0047] In one embodiment, the first horizontal direction X is perpendicular to the second horizontal direction Y. The accommodating holes of the sample box 200 are usually arranged in a horizontal and vertical manner so that the sample tubes 300 are neatly arranged in a horizontal and vertical manner. The first horizontal direction X is perpendicular to the second horizontal direction Y. When the first horizontal direction X is the horizontal direction of the sample box 200, the second horizontal direction Y is the longitudinal direction of the sample box 200. Therefore, the grasping mechanism 10 can grasp a row of sample tubes 300 in one grasping operation, and then move in the longitudinal direction to gradually grasp each row of sample tubes 300.

[0048] See also Figure 3 The grabbing mechanism 10 further includes a power component 12, which is used to provide power for each grabbing component 11 to grab the sample tube 300, so that the grabbing component 11 can grab the sample tube 300. The power component 12 can be designed accordingly according to the structure of the grabbing component 11, for example, the power component 12 can be an air pump, a motor, or a cylinder, etc.

[0049] See also Figure 3 and Figure 4 In one embodiment, the power component 12 is an air pump 121, and the grasping component 11 is a vacuum adsorption gun 111; the grasping mechanism 10 also includes an adsorption tube 13, the adsorption tube 13 connects the air pump 121 and all the vacuum adsorption guns 111, and the rotation drive mechanism 20 is connected to the adsorption tube 13, which is used to drive the adsorption tube 13 to rotate to drive the vacuum adsorption gun 111 to rotate. In this embodiment, the air pump 121 is a micro air pump, which occupies a small space and is easy to install. In specific implementation, the air pump 121 generates negative pressure, so that the vacuum adsorption gun 111 is adsorbed onto the tube cover of the sample tube 300, so that the vacuum adsorption gun 111 can grasp the sample tube 300.

[0050] By adsorbing the vacuum adsorption gun 111 onto the tube cap of the sample tube 300, on the one hand, it can prevent the grabbing component 11 from blocking the information identification code on the tube wall; on the other hand, it can also prevent the grabbing component 11 from damaging the information identification code due to excessive grabbing force when grabbing the sample tube 300.

[0051] Moreover, in this embodiment, one air pump 121 provides negative pressure for all vacuum adsorption guns 111, so that all vacuum adsorption guns 111 have consistent actions in grabbing the sample tube 300. Of course, in other embodiments, it is also possible that the grabbing mechanism 10 is provided with multiple air pumps 121, and each air pump 121 corresponds to a vacuum adsorption gun 111; when this embodiment is adopted, it can be ensured that sufficient negative pressure can be provided for each vacuum adsorption gun 111, and when one of the air pumps 121 fails, it will not affect other vacuum adsorption guns 111.

[0052] It can be understood that in other embodiments, the grasping component 11 can also be a clamping claw, and the power component 12 can also be a power component that controls the opening or closing of the clamping claw.

[0053] See also Figure 3 and Figure 4 The vacuum adsorption gun 111 includes a gun body 1111 and an adsorption gun head 1112. The adsorption gun head 1112 is connected to the gun body 1111. The end of the gun body 1111 away from the adsorption gun head 1112 is connected to the adsorption tube 13. The end of the adsorption gun head 1112 away from the gun body 1111 is used to be inserted into the groove at the top of the tube cover of the sample tube 300. The tube cover of the sample tube 300 is usually a rubber stopper, and there is a groove on the top of the rubber stopper. The tube cover is adsorbed by inserting the adsorption gun head 1112 into the groove. The groove has a small space and less air, which is conducive to the adsorption of the sample tube 300 by the vacuum adsorption gun 111. In this way, the design of the sample tube 300 can be fully utilized to realize the rapid grasping of the sample tube 300. In specific implementation, the outer contour of the adsorption gun head 1112 can be designed to match the groove.

[0054] See also Figure 3 and Figure 4 The adsorption tube 13 includes a soft tube 131 and a plurality of hard tubes 132. The soft tube 131 is connected between the air pump 121 and the plurality of hard tubes 132. The end of the soft tube 131 away from the air pump 121 is provided with a plurality of interfaces, each interface is connected to a hard tube 132. The hard tubes 132 correspond to the vacuum adsorption guns 111 one by one, and the rotation drive mechanism 20 is connected to the hard tubes 132. The rotation drive mechanism 20 drives the hard tubes 132 to rotate, so as to drive the vacuum adsorption guns 111 to rotate.

[0055] The soft tube 131 includes a soft main tube 1311 and multiple soft branch tubes 1312. One end of the soft main tube 1311 is connected to the air pump 121, and the other end is connected to multiple soft branch tubes 1312. The end of each soft branch tube 1312 away from the soft main tube 1311 is connected to a hard tube 132.

[0056] In one embodiment, the rotation drive mechanism 20 is used to drive the hard tube 132 to rotate in the first direction one time and in the second direction the next time; wherein the first direction and the second direction are opposite. For example, the first direction is clockwise and the second direction is counterclockwise; or the first direction is counterclockwise and the second direction is clockwise.

[0057] When the rotary drive mechanism 20 drives the hard tube 132 to rotate, it can also drive the soft tube 131 to rotate. If the rotary drive mechanism 20 drives the hard tube 132 to rotate in the same direction, the soft tube 131 will be entangled after multiple rotations, affecting the negative pressure transmission. By setting the rotary drive mechanism 20 to drive the hard tube 132 to rotate in a first direction for the first time and in a second direction opposite to the first direction for the next time, the soft tube 131 can be prevented from being entangled.

[0058] In another embodiment, the adsorption tube 13 may further include a plurality of rotating joints, which are connected between the soft tube 131 and the hard tube 132 so that the hard tube 132 can rotate relative to the soft tube 131. In this way, when the rotation drive mechanism 20 drives the hard tube 132 to rotate, the hard tube 132 rotates relative to the soft tube 131 without driving the soft tube 131 to rotate, thereby preventing the soft tube 131 from being entangled.

[0059] In one embodiment, the vacuum adsorption gun 111 is detachably connected to the adsorption tube 13. With such a configuration, the number of vacuum adsorption guns 111 can be adjusted. For example, when the number of vacuum adsorption guns 111 is greater than the number of sample tubes 300 carried on the sample box 200 along the first horizontal direction X, the redundant vacuum adsorption guns 111 can be detached. In addition, by detachably arranging the vacuum adsorption gun 111, it is convenient to maintain and replace the vacuum adsorption gun 111.

[0060] In another embodiment, the vacuum adsorption gun 111 may also be fixedly connected to the adsorption tube 13 .

[0061] See also Figure 2 and Figure 3 The biological sample scanning device 100 also includes a support frame 60, and the grasping mechanism 10, the rotation drive mechanism 20, the horizontal drive mechanism 30, the lifting drive mechanism 40 and the image acquisition device 50 are all installed on the support frame 60, and the support frame 60 supports the grasping mechanism 10, the rotation drive mechanism 20, the horizontal drive mechanism 30, the lifting drive mechanism 40 and the image acquisition device 50.

In this way, when the grabbing component 11 moves to any position along the vertical direction and the second horizontal direction Y, the image acquisition device 50 can capture the image of the information identification code of the sample tube 300 grabbed by the grabbing component 11.

[0063] See also Figure 2 and Figure 3 The support frame 60 includes a base 61 and a support column 62, the support column 62 is connected to one side of the base 61 and extends upward from the base 61, the grabbing component 11, the rotation drive mechanism 20, the horizontal drive mechanism 30, the lifting drive mechanism 40 and the image acquisition device 50 are all installed on the support column 62 and located above the base 61, and the air pump 121 is installed in the base 61. In a specific implementation, the sample box 200 is placed on the base 61, and the grabbing component 11 is located above the sample box 200.

[0064] It is understood that in other embodiments, the support frame 60 may not be provided with the base 61. When this embodiment is adopted, the support column 62 is fixed on the workbench, and the sample box 200 is directly placed on the workbench.

[0065] In one embodiment, a positioning mark is provided on the base 61, and there is a certain distance between the positioning mark and the pillar 62. By providing the positioning mark, the sample box 200 can be placed on the side of the positioning mark away from the pillar 62 to ensure that there is a certain distance between the sample box 200 and the image acquisition device 50, so as to solve the problem that a clear image cannot be obtained due to the close distance between the image acquisition device 50 and the sample tube 300, thereby enabling the image acquisition device 50 to obtain a clear image of the information identification code. The positioning mark can be a structural component such as a marking line or a marking symbol.

[0066] In one embodiment, the rotation drive mechanism 20 is used to drive all the gripping components 11 to rotate synchronously around their respective vertical axes, and the image acquisition device 50 is used to simultaneously acquire images of the information identification codes of the sample tubes 300 captured by all the gripping components 11. This arrangement can increase the speed of acquiring images of the information identification codes. Of course, in other embodiments, it is also possible for the image acquisition device 50 to acquire images of the information identification codes of the sample tubes 300 captured by each gripping component 11 respectively.

[0067] The image acquisition device 50 may be a camera.

[0068] See also Figure 4The rotary drive mechanism 20 includes a rotary drive member 21 and a rotary transmission member 22, and the rotary transmission member 22 is connected between the rotary drive member 21 and all the hard tubes 132. The rotary drive member 21 can be a motor, and the rotary transmission member 22 can be a gear belt transmission member or a gear rack transmission member. The output shaft of the motor is connected to the driving gear, and each hard tube 132 is connected to a driven gear. The belt or rack transmission is connected to the outer periphery of the driving gear and all the driven gears. The motor drives the driving gear to rotate, driving all the driven gears to rotate, and then drives all the hard tubes 132 and the grabbing components 11 to rotate, so as to realize the synchronous rotation of all the grabbing components 11.

In this way, manual participation can be reduced and the mechanized operation of the biological sample code scanning device can be improved.

[0073] See also Figure 1 and Figure 2In one embodiment, the biological sample scanning device 100 further includes an information input device 91, which is electrically connected to the controller 80 and is used to input control information to the controller 80.
