[0026] Here, it also needs to be explained that, in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0027] In addition, it should be pointed out that the terms "comprising", "containing" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. In the following description, the terms "first, second,... " are only to distinguish different objects and do not mean that the objects have the same or relationship. It should be understood that the orientation described by the orientation terms "above", "below", "inner", "outer" and the like is the orientation in the normal use state.

[0028] In the following specific embodiments, the test tube transfer device can be used for batch transfer of test tubes to provide a prerequisite for batch cleaning of test tubes. Specifically, after the test tube completes the relevant function of the test, the residual material in the test tube needs to be cleaned before the test tube can be reused to avoid the influence of the residual material in the test tube on the subsequent test. At this time, the test tube needs to be batch transferred by the test tube transfer device. The structure and function of the test tube transfer device will be exemplarily described below.

[0029] In some embodiments, as shown in Figure 1 The test tube transfer device 1 includes a first clamping member 10, a second clamping member 20 and a carrying structure 30.

[0030] The first clamping member 10 has a plurality of first clamping holes 11 arranged at intervals, and the second clamping member 20 is slidably connected with the first clamping member 10, and the second clamping member 20 has a plurality of second clamping holes 21 arranged at intervals. The depth direction of the second clamping hole 21 is parallel to the depth direction of the first clamping hole 11, and each second clamping hole 21 is in communication with each first clamping hole 11, and at the same time, the second clamping member 20 can slide relative to the first clamping member 10 in the first direction (the first direction is shown by the arrow in Figure 1 It can be understood that by sliding the second clamping member 10 relative to the first clamping member 20, the first clamping hole 11 and the second clamping hole 21 can be shifted in the first direction, so that the radial dimension of the space surrounded by the inner walls of the first clamping hole 11 and the second clamping hole 21 changes, thereby achieving clamping and releasing of the test tube. Moreover, the first clamping hole 11 and the second clamping hole 21 have a plurality of them, and the simultaneous clamping and releasing of a plurality of test tubes can be achieved by sliding the second clamping member 20, that is, batch transfer of test tubes can be achieved.

[0031] It should be noted that, since the sliding direction of the second clamping member 20 is perpendicular to the depth direction of the first clamping hole 11, during the movement of the second clamping member 20 along the first direction, the size of the space surrounded by each first clamping hole 11 and second clamping hole 21 changes at the same speed, so that the size of the clamping force exerted by each first clamping hole 11 and each second clamping hole 21 on each test tube changes synchronously, and further, the clamping of the test tube by the test tube transfer device 1 is more reliable.

[0032] Meanwhile, the carrying structure 30 is connected with the first clamping member 10, for moving the first clamping member 10 and the second clamping member 20 between the first position and the second position, so as to be able to carry the test tubes from the first position to the second position, and connecting the carrying structure 30 with the first clamping member 10 can decouple the movement of the first clamping member 10 and the second clamping member 20 as a whole from the movement of the second clamping member 20 relative to the first clamping member 10, thereby reducing the difficulty of motion control of the test tube transfer device. The process of transferring the test tubes from the first position to the second position will be exemplarily described below in combination with the movement state of the first clamping member 10 and the second clamping member 20.

[0033] The carrying structure 30 drives the first clamping member 10 and the second clamping member 20 to move to the first position, and at the same time, the second clamping member 20 slides along one side of the first direction, so that the center axes of the first clamping hole 11 and the second clamping hole 21 coincide, and the space surrounded by the first clamping hole 11 and the second clamping hole 21 has the maximum radial dimension; in this state, the first clamping hole 11 and the second clamping hole 21 are respectively sleeved on the outside of the plurality of test tubes, and then the second clamping member 20 slides along the other side of the first direction, so that the center axes of the first clamping hole 11 and the second clamping hole 21 are dislocated, the radial dimension of the space surrounded by the first clamping hole 11 and the second clamping hole 21 is reduced, and the inner wall of one side of the first clamping hole 11 and the inner wall of the other side of the second clamping hole 21 opposite to the one side can clamp each test tube; in the state that each first clamping hole 11 and second clamping hole 21 batch clamps the plurality of test tubes, the carrying structure 30 carries the first clamping member 10, the second clamping member 20 and the clamped test tubes as a whole to the second position, at this time, the second clamping member 20 slides along the first direction to make the center axes of the first clamping hole 11 and the second clamping hole 21 coincide, so that the inner walls of the first clamping hole 11 and the second clamping hole 21 loosen the clamping of the test tubes, so that the test tubes can be released to the second position.

[0034] The utility model discloses an embodiment provides a test tube transfer device, the test tube transfer device includes: the first clamping piece with a plurality of first clamping holes, the second clamping piece with a plurality of second clamping holes and the carrying structure connected with the first clamping piece, wherein each first clamping hole and each second clamping hole are communicated, and the second clamping piece can slide relative to the first clamping piece in the first direction, the first direction is perpendicular to the depth direction of the first clamping hole, and the radial dimension of the space formed by the first clamping hole and the second clamping hole can be changed by the sliding of the second clamping piece relative to the first clamping piece, so that the first clamping hole and the second clamping hole can clamp or release the test tube, and because the number of the first clamping hole and the second clamping hole is multiple, a plurality of test tubes can be clamped and released in batches at the same time, simultaneously, the carrying structure can carry the first clamping piece, the second clamping piece and the plurality of test tubes clamped by the first clamping piece and the second clamping piece in batches, so that the test tube transfer device can carry a plurality of test tubes in batches.

[0035] In some embodiments, as shown in Figure 2 The first clamping piece 10 includes a body portion 12 and a guide portion 13, each first clamping hole 11 is arranged on the body portion 12, the guide portion 13 protrudes from the body portion, and the guide portion 13 and the body portion 12 form a guide cavity 14, it can be understood that the guide portion 13 extends along a fold line or a curve after extending from the surface of the body portion 12, so that the surface of the guide portion 13 can form the guide cavity 14 with the surface of the body portion 12, for example, the guide portion 13 includes a first portion and a second portion, the first portion extends from the outer surface of the body portion 12 and the extension direction of the first portion is parallel to the depth direction of the first clamping hole 11, and the second portion extends from the outer surface of the first portion and the extension direction of the second portion is perpendicular to the depth direction of the first clamping hole 11, that is, the first portion and the second portion are bent to form a structure similar to L shape, so that the first portion, the second portion and the body portion 12 can form the guide cavity 14, wherein the guide cavity 14 is communicated with the first clamping hole 11 and at least part of the second clamping piece 20 is located in the guide cavity 14, the guide of the second clamping piece 20 is realized by the acting force between the second clamping piece 20 and the inner wall of the guide cavity 14, so as to limit the movement of the second clamping piece 20 in other directions except the first direction.

[0036] Optionally, in combination with Figure 2 And Figure 3 The guide cavity 14 has an opening 141, the opening 141 faces the first direction (the first direction is shown by the arrow direction in Figure 3 ), and part of the second clamping piece 20 can be located outside the guide cavity 14, so that the second clamping piece 20 can slide in a larger range in the first direction without changing the size of the first clamping piece 10 in the first direction.

[0037] In some embodiments, as shown in Figure 4 The inner walls of the first clamping hole 11 and the second clamping hole 21 are provided with flexible pads 40, which are in direct contact with the test tube in the state of clamping the test tube by the inner walls of the first clamping hole 11 and the second clamping hole 21, thereby reducing the risk of test tube breakage caused by hard contact between the clamping hole and the test tube.

[0038] In some embodiments, as shown in Figure 5 The test tube transfer device 1 further comprises an air pump 51 and an air pipe 52, the air pipe 52 connecting the air pump 51 and the second clamping piece 20, the air pressure in the air pipe 52 being controlled by the air pump 51 to drive the second clamping piece 20 to slide in the first direction relative to the first clamping piece 10 by air pressure. Compared with driving the second clamping piece 20 by mechanical rigid structure to transfer kinetic energy, driving the second clamping piece 20 by air flow, when the second clamping piece 20 bears impact load, the gas can be compressed to a certain extent, so as to realize the function of air spring to a certain extent by the compression of the gas to buffer the impact load, thereby making the sliding of the second clamping piece 20 more smooth and reducing the possibility of breakage of the test tube under the action of the impact load.

[0039] Optionally, the air pump 51 is located in the carrying structure 30, and the air pipe 52 passes through the air pump 51 and is connected to the second clamping piece 20. During the movement of the carrying structure 30 driving the first clamping piece 10 and the second clamping piece 20, the distance between the air pump 51 and the second clamping piece 20 does not change greatly, so that the connection between the air pipe 52 and the second clamping piece 20 is more reliable.

[0040] In some embodiments, as shown in Figure 5 The air pipe 52 has a pressure relief valve 521, which is in a closed state under the condition of no external force, and the air pipe 52 can normally transmit air pressure to drive the second clamping piece 20. Under the condition of external force, the pressure relief valve 521 can be opened, at which time the air pressure in the air pipe 52 is discharged by the pressure relief valve 521 so that the air pressure in the air pipe 52 cannot continue to drive the second clamping piece 20 to move; at the same time, the first clamping piece 10 has a limiting piece 15, and the second clamping piece 20 is in the first direction (the first direction is as shown in Figure 5The sliding on the position shown by the middle arrow can make the limiting piece 15 abut against the pressure relief valve 521 and make the pressure relief valve be in an open state. It can be understood that, when the second clamping piece 20 moves to the target position, the limiting piece 15 abuts against the pressure relief valve 521 to make the pressure relief valve 521 open, so that the air pressure in the air pipe 52 cannot continue to drive the second clamping piece 20 to move, so as to make the second clamping piece 20 remain at the target position. At this time, the clamping force of the first clamping piece 10 and the second clamping piece 20 on the test tube no longer continues to increase. It can be understood that, by arranging the pressure relief valve 521 and the limiting piece 15, the maximum clamping force between the first clamping piece 10 and the second clamping piece 20 is limited, so as to reduce the risk of test tube breakage due to excessive clamping force.

[0041] In some embodiments, as shown in Figure 5 The limiting piece 15 is in sliding connection with the first clamping piece 10, and the limiting piece 15 can slide relative to the first clamping piece 10, or the size of the limiting piece 15 in the first direction is variable, so that the position at which the limiting piece 15 begins to abut against the pressure relief valve 521 is adjustable, and then the maximum clamping force between the first clamping piece 10 and the second clamping piece 20 is adjustable. While being able to reliably clamp the test tube, the risk of test tube breakage due to excessive clamping force is reduced. Wherein the size of the limiting piece 15 in the first direction is variable, which can be realized by the relative movement between two parts. For example, the limiting piece 15 includes a first limiting part and a second limiting part. The first limiting part is fixedly connected with the first clamping piece 10, and the second limiting part is used to abut against the pressure relief valve 521. The first limiting part and the second limiting part are connected by threads. By rotating the second limiting part, the second limiting part can move relative to the first limiting part in the first direction, so as to adjust the size of the limiting piece 15 in the first direction.

[0042] In some embodiments, as shown in Figure 1As shown, the carrying structure 30 comprises: a turnover part 31 and a carrying part 32. The turnover part 31 is fixedly connected with the first clamping piece 10 and can drive the first clamping piece 10 to turn over, the rotation center axis of the first clamping piece 10 is perpendicular to the first direction and perpendicular to the depth direction of the first clamping hole 11, the posture of the clamped test tube can be changed by making the first clamping piece 10 turn over around the rotation center axis, specifically, the orientation of the opening of the test tube can be changed, for example, the opening of the test tube is changed from upward to downward; at the same time, the carrying part 32 is connected with the turnover part 31 and is used for moving the first clamping piece 10 and the second clamping piece 20 between the first position and the second position, so as to transfer the test tube from the first position to the second position. It can be understood that the posture adjustment of the test tube and the position carrying of the test tube are realized by two structures respectively, which enriches the function of the test tube transfer device 1 and reduces the control difficulty of the test tube transfer device 1. The turnover part 31 can also pour out the residual liquid in the test tube by inverting the test tube, that is, the test tube is transferred above the waste liquid containing device, and the waste liquid in the test tube can be introduced into the waste liquid containing device by turning over the test tube by the turnover part 31.

[0043] In some embodiments, as Figure 6 shown, the test tube transfer device 1 further comprises a jacking structure 60, the jacking structure 60 is located at the first position and is used for jacking the test tube at the first position, specifically, each test tube located at the first position is contained in the test tube rack, only a small part of the top of the test tube extends out of the test tube rack, in this state, it is difficult to clamp the test tube, by setting the jacking structure 60 at the first position, the jacking structure 60 is arranged at the bottom of the test tube, when the test tube needs to be carried, the jacking structure 60 is jacked to make more parts of the test tube extend out of the test tube rack, so that the test tube can be clamped by the first clamping piece 10 and the second clamping piece 20.

[0044] The utility model embodiment further provides a test tube cleaning system for cleaning the test tube used in the test process, so that the cleaned test tube can be reused, and the structure of the test tube cleaning system is exemplarily described below.

[0045] In some embodiments, as Figure 7 shown, the test tube cleaning system comprises: a cleaning device 2 and a test tube transfer device 1 as shown in any one of the drawings Figures 1 to 6 of the drawings, wherein the test tube transfer device 1 is used for transferring a plurality of test tubes stored at the first position to the second position and placing the test tubes into the cleaning device 2 located at the second position, so that the cleaning device 2 can clean the test tubes in batches, and the cleaning device 2 can clean the test tubes in any way, for example, the cleaning device 2 can clean the test tubes by outputting water flow, and for example, the cleaning device 2 can clean the test tubes by ultrasonic waves.

[0046] In some embodiments, the combination Figure 1 and Figure 7 , Figure 1 The carrying structure 30 in the above embodiment includes a turnover portion 31, and the cleaning device 2 includes a vertical upward cleaning nozzle 201, the turnover portion 31 is used to turn over the first clamping member 10, the second clamping member 20 and the test tube as a whole, so that the test tube is in a posture with the test tube opening vertically downward, and meanwhile, the carrying structure 30 is also used to carry the test tube in this posture to the second position and invert the test tube on the cleaning nozzle 201, at this time, the cleaning nozzle 201 can spray water upward to clean the test tube, and the sprayed water can flow out of the test tube under the action of gravity after cleaning the residual substances in the test tube, thereby reducing the amount of residual liquid in the test tube after cleaning.

[0047] Optionally, the turnover portion is also used to transfer the test tube to a third position, and the test tube cleaning system further includes a drying rack, and the carrying structure is also used to invert the cleaned test tube on the drying rack, so that the test tube can be dried, and the dried test tube can be reused in the subsequent test process.

[0048] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited.
