Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.

Referring to fig. 1, fig. 1 discloses a schematic structural diagram of a test tube detection and reading apparatus in an embodiment of the present application. The test tube detecting and reading device 100 may include a first moving assembly 10, a limiting member 20 connected to the first moving assembly 10 and configured to limit the first moving assembly 10, an elastic member 30 connected to the limiting member 20, an optical coupling element 40 disposed on one side of the limiting member 20, a second moving assembly 50 connected to the limiting member 20 and the elastic member 30, and a signal detecting assembly 60 disposed on the second moving assembly 50. In some embodiments, the second moving element 50 can control the elastic element 30 to deform and generate an elastic force to drive the limiting element 20 to reciprocate along a predetermined direction, such as a direction parallel to the axis L (see fig. 11), so as to drive the first moving element 10 to reciprocate along the predetermined direction. The light coupling element 40 further cooperates with the signal detection assembly 60 to automatically detect the presence of a test tube 90 (shown in fig. 11) upon movement of the first moving assembly 10 in a preset direction. Further, upon detecting the presence of the test tube, the first moving assembly 10 is configured to rotate the test tube 90 in a preset plane (not shown) perpendicular to the preset direction, so that the barcode (not shown) of the test tube 90 is read.

Referring to fig. 2, fig. 2 is an exploded perspective view of the first motion assembly of fig. 1. In some embodiments, the first motion assembly 10 includes a first motor 11, a rotating member 12 drivingly connected to the first motor 11, and a first stationary member 13 connected to the first motor 11.

The first motor 11 can provide driving power for the first moving assembly 10, so that the first moving assembly 10 can press the test tube 90 and rotate the test tube 90 in a predetermined plane. As shown in fig. 2, the first motor 11 may include a first motor main body 111, a first connection part 112 provided at an end of the first motor main body 111, and a first rotation shaft 113 passing through the first connection part 112 and rotatably connected to the first motor main body 111.

In the embodiment shown in fig. 2, the first motor main body 111 has a substantially rectangular parallelepiped structure. Of course, in other embodiments, the first motor main body 111 may also take a cylindrical shape, a cubic shape, and the like, and the shape of the first motor main body 111 is not particularly limited in this application.

The first connecting portion 112 is connected to an end portion of the first motor main body 111 and is connected to the first fixing member 13, so that the first motor 11 can be connected to the first fixing member 13. In some embodiments, the first connection portion 112 and the first motor main body 111 may be fixed by gluing, plugging, and the like. In some embodiments, the first connecting portion 112 and the first fixing member 13 can be connected and fixed by gluing, inserting, or the like.

Referring further to fig. 2, the end of the first motor main body 111 provided with the first connecting portion 112 may further be provided with at least one first groove 1112, so that the first motor main body 111 and the first fixing member 13 are further stably mounted and connected through the first groove 1112. Alternatively, the first grooves 1112 are four in number and uniformly distributed at the end of the first motor main body 111 centering on the first rotation shaft 113. In assembly, fasteners (not shown) may be used to penetrate the first fixing members 13 one by one, so that the first motor 11, for example, the first motor main body 111 is securely mounted on the first fixing members 13. It is understood that the number of the first grooves 1112 can be adjusted according to the actual situation, for example, three or five grooves are also possible. In some embodiments, the fastener may be a bolt or a screw, and the first groove 1112 may be configured as a groove with a thread structure, and thus the first fixing member 13 and the first motor 11 may be fixedly connected to each other by means of a threaded connection through the bolt or the screw.

The first rotating shaft 113 extends from the first connecting portion 112 in a direction away from the first motor main body 111. Moreover, the first rotating shaft 113 is rotatably disposed through the first fixing element 13 and is in transmission connection with the rotating element 12, so that the first motor 11 drives the rotating element 12 to rotate in the predetermined plane.

In one embodiment, the first shaft 113 is a screw. When the first moving assembly 10 is in operation, the first motor 11 can provide driving power for the first moving assembly 10, so that the first moving assembly 10, for example, the rotating member 12, can press the test tube 90, and can drive the rotating member 12 to rotate in the preset plane through the rotation of the screw, thereby realizing that the first moving assembly 10 drives the test tube 90 to rotate in the preset plane, so that the barcode on the test tube 90 is scanned and read by the barcode scanning member 70 (see fig. 11).

Referring again to fig. 2, the rotating element 12 may include a rotating base 121 and a rotating body 122 at least partially accommodated in the rotating base 121. One end of the rotating body 122 is connected to the first rotating shaft 113 of the first motor 11, and the other end is at least partially accommodated in the rotating base 121.

Specifically, the rotating base 121 may have a plate-shaped structure, and although the rotating base 121 is illustrated as having a cylindrical shape, this is not necessarily required. The rotating substrate 121 may have any other shape as desired for a particular application. For example, the rotating base 121 may have one of a circular truncated cone shape, a rectangular shape, an ellipsoid-like shape, and the like, and may be changed in shape according to actual conditions. Further, a second groove 1211 is disposed on the top of the rotating base 121, such that the rotating body 122 can be partially received in the second groove 1211, and the rotating body 122 is connected to the rotating base 121 in a matching manner, for example, in a rotating manner. Alternatively, the shape of the second groove 1211 may be cylindrical, for example, cylindrical.

The rotating body 122 includes a base 1221 and a base 1222 extending from the base 1221. When the rotary member 12 is assembled with the first motor 11, the base portion 1222 is located on a side of the base portion 1221 adjacent to the first motor main body 111 or the first connecting portion 112. In some embodiments, the base 1221 has an outer diameter that is less than the outer diameter of the base 1222.

Alternatively, the base 1221 may have a cylindrical structure, specifically, a cylindrical shape, adapted to the shape of the second groove 1211, and of course, other cylindrical shapes may also be adopted as long as the shape of the second groove 1211 is adapted to the shape of the base 1221, so that the base 1221 can be accommodated in the second groove 1211. In one embodiment, the outer diameter of one end of the base 1221 away from the base 1222 is larger than the outer diameter of the other end of the base 1222 close to the base 1222, so that the connection of the rotating body 122 and the rotating base 121 is more secure.

Similarly, the base 1222 may also be a cylindrical structure, and particularly, the base 1222 may be configured as other cylindrical structures, for example: a prismatic structure. Further, the top of the base 1222 is provided with a third groove 1222a such that the first rotating shaft 113 can be received in the third groove 1222a, thereby enabling the first motor 11 to provide driving power for the rotating member 12. Further, the base 1222 is further provided at its outer circumference with at least one first mounting hole 1222b. When the first rotating shaft 113 is received in the third recess 1222a, a fastener, such as a screw or a bolt (not shown), can be inserted through the first mounting hole 1222b, such that the rotating member 12, such as the rotating body 122, can be fixedly mounted on the first motor 11, such as the first rotating shaft 113, and thus the rotating member 12 can be stably driven to rotate by the first rotating shaft 113.

With reference to fig. 2, the first fixing member 13 may include a first side plate 131 and a first bottom plate 132 extending from the first side plate 131.

The first side plate 131 is a plate-shaped structure, and is specifically shaped like an L, but may be provided in other shapes, such as an oval, a rectangle, etc., and the shape may be changed according to actual situations. As shown in fig. 2, the first side plate 131 is provided with two second mounting holes 1311, 1312, so that the first moving component 10, such as the first fixing component 13, can be connected and fixed with the limiting component 20 through the second mounting holes 1311, 1312. Alternatively, although the number of the second mounting holes is shown as two in fig. 2, this is not necessary, and it is understood that the number of the second mounting holes may also be adjusted according to the actual situation, for example, it may also be one or three, etc., as long as the first moving component 10, for example, the first fixing component 13, can be connected and fixed with the limiting component 20. In some embodiments, the first side plate 131 may further be provided with a third mounting hole 1313 for passing the electric wire of the first motor 11, so as to reduce damage to the electric wire during the movement of the first moving assembly 10. It is understood that in other embodiments, third mounting hole 1313 may be omitted.

Similarly, the first bottom plate 132 may also be a plate-shaped structure, specifically a quasi-rectangular structure, and of course, may also be set to other shapes, and the shape may be changed specifically according to actual situations, and is not described any more. Optionally, the first bottom plate 132 extends from the first side plate 131 and may be disposed substantially perpendicular to the first side plate 131. The first connecting portion 112 and the first rotating shaft 113 of the first motor 11 penetrate through the first base plate 132, and the end surface of the first motor main body 111 abuts against the end surface of the first base plate 132, so as to more firmly bear the first motor 11, so that the first moving assembly 10 can move up and down along a direction parallel to the axis L.

As shown in fig. 2, the first base plate 132 may be provided with a first through hole 1321 penetrating the first base plate 132 and a fourth mounting hole 1322 provided at one side of the first through hole 1321. In some embodiments, the first connecting portion 112 may be disposed in the first through hole 1321 and interference-fitted with the first through hole 1321, or abut on an inner wall of the first through hole 1321, so that the first motor 11 and the first fixing member 13 are stably connected to each other. Of course, in other embodiments, the first connection portion 112 may be disposed at a gap from the first through hole 1321. The first shaft 113 can be inserted into the first through hole 1321 and received in the third recess 1222 a.

The fourth mounting hole 1322 may fixedly connect the first motor main body 111 with the first fixing member 13, for example, the first base plate 132, and when assembled, a fastener, for example, a bolt or a screw (not shown) may be inserted through the fourth mounting hole 1322 and the first groove 1112, so that the first motor 11, for example, the first motor main body 111, and the first fixing member 13, for example, the first base plate 132 are tightly fitted. It is understood that the fourth mounting hole 1322 may be plural. In an embodiment, the fourth mounting holes 1322 may be four and uniformly distributed around the first through hole 1321 centering on the first through hole 1321, so that the first motor body 111 is securely mounted on the first base plate 132. Of course, the number of the fourth mounting holes 1322 may be determined according to the actual application, and is not limited herein.

Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram illustrating a position limiting element in the embodiment shown in fig. 1 of the present application, and fig. 4 is a cross-sectional view illustrating the position limiting element in the embodiment shown in fig. 3 of the present application. As shown in fig. 3, the position-limiting member 20 may be a rectangular structure, such as a rectangular parallelepiped or a square cube. The limiting member 20 may include a top portion 21, a first side portion 22 extending from the top portion 21, and a second side portion 23 extending from the first side portion 22 and connected to the top portion 21 to form a rectangular structure. The top 21 may include a second through hole 211, a third through hole 212 disposed on one side of the second through hole 211, and a fourth through hole 213 disposed on the other side of the second through hole 211 away from the third through hole 212. As shown in fig. 4, the second through hole 211, the third through hole 212, and the fourth through hole 213 respectively penetrate through the limiting member 20 along a direction parallel to the axis L (as shown in fig. 11), so that the second moving assembly 50 can be connected to the limiting member 20 through the second through hole 211, the third through hole 212, and the fourth through hole 213. In an embodiment, the center positions of the third through hole 212, the second through hole 211, and the fourth through hole 213 may be on the same axis and arranged in sequence. In another embodiment, the aperture of the third through hole 212 is equal to the aperture of the fourth through hole 213, and the aperture of the second through hole 211 is larger than the aperture of the third through hole 212.

Referring to fig. 4, the second through hole 211 may be a cylinder structure, such as a cylinder structure, but other cylinder structures are also possible as long as the second moving element 50 can be connected to the limiting member 20 through the second through hole 211. As shown in fig. 4, the third through hole 212 may have a bolt-like structure, which may include a first section 212a near the top 21 and a second section 212b extending from the first section 212a away from the top 21. The third through hole 212 may be substantially in a stepped hole shape, and the aperture of the first section 212a is larger than that of the second section 212b, so that the elastic element 30 is at least partially exposed at the top portion 21 of the limiting element 20, and an end of the elastic element 30 away from the top portion 21 may abut against the second moving element 50. Similarly, the fourth through hole 213 may also include a third segment 213a and a fourth segment 213b, and the structure thereof is substantially the same as that of the third through hole 212, and is not repeated. Optionally, the top portion 21 may further include two fifth through holes 214 and 215 disposed on one side of the third through hole 212 and close to the first side portion 22. Specifically, when the second moving member 50 is disassembled, the two fifth through holes 214 and 215 are configured to allow a disassembling tool to be inserted into the two fifth through holes 214 and 215, so as to disassemble and assemble the second moving member 50.

Referring to fig. 3 again, in order to be matched with the second mounting holes 1311, 1312 on the first side plate 131, two fourth grooves 221, 222 may be disposed on the first side portion 22, so that the first fixing member 13, such as the first side plate 131, may be fixedly mounted on the limiting member 20, such as the first side portion 22. During assembly, a fastener, such as a bolt (not shown), may be inserted through the second mounting holes 1311, 1312 and received in the fourth grooves 221, 222, respectively, so that the first fixing member 13, such as the first side plate 131, may be fixedly mounted on the limiting member 20, such as the first side portion 22, and the first moving component 10 may be connected to the limiting member 20. When the second motion assembly 50 drives the limiting member 20 to move up and down along the direction parallel to the axis L, the limiting member 20 can be used to limit the distance that the first motion assembly 10 moves up and down along the direction parallel to the axis L. It is understood that the number of the fourth grooves 221, 222 is adapted to the number of the second mounting holes 1311, 1312, and although the number of the fourth grooves is two, the number of the fourth grooves can be adjusted according to the actual situation as long as the first fixing member 13, such as the first side plate 131, can be fixedly mounted on the limiting member 20, such as the first side portion 22.

Similarly, two fifth recesses 231, 232 may also be provided on the second side portion 23, so that the light coupling element 40 may be fixedly mounted on the limiting member 20, for example, the second side portion 23.

Referring to fig. 5, fig. 5 is a cross-sectional view of the limiting member, the elastic member, the optical coupling element and the second moving component of the embodiment shown in fig. 1 of the present application after assembly. Alternatively, the elastic member 30 may be one of a spring, a damper or other elastic device, etc., as long as it can be driven to generate elastic deformation to provide elastic force so that the first moving assembly 10 can move up and down along the direction parallel to the axis L, and the specific structure thereof may be other existing structures, which is not limited in this application. The present application is described below with respect to the elastic member 30 as a compression spring.

As shown in fig. 5, the elastic member 30 may include a first elastic member 31 and a second elastic member 32 disposed in parallel, wherein one end of the first elastic member 31 may abut against one side of the second moving component 50, and the other end may be at least partially received in the third through hole 212, one end of the second elastic member 32 may abut against one side of the second moving component 50, and the other end may be at least partially received in the fourth through hole 213, that is: one end of each of the first elastic member 31 and the second elastic member 32 abuts against the second motion assembly 50 and the other end thereof is at least partially accommodated in the limiting member 20. In some embodiments, one end of each of the first elastic member 31 and the second elastic member 32 abutting against the second motion assembly 50 is a free end, and the other end at least partially received in the limiting member 20 is a fixed end. The first moving component 10 is fixedly connected to the first side portion 22 of the limiting member 20, and when the limiting member 20 reciprocates along the preset direction, the first elastic member 31 and the second elastic member 32 are driven to be compressed downward along a direction parallel to the axis L to generate elastic deformation or return upward to an initial state, so as to provide elastic force for the first moving component 10, and thus the first moving component 10 is driven to move up and down along the direction parallel to the axis L. It is understood that when the limiting member 20 moves in the predetermined direction toward the second moving component 50, the elastic member 30, such as the first elastic member 31 and the second elastic member 32, can also prevent the limiting member 20 from directly impacting the second moving component 50, so as to protect the second moving component 50.

It will be appreciated that although the elastic member 30 is shown as including the first elastic member 31 and the second elastic member 32, this is not required, for example, in some embodiments, the number of the elastic members 30 may be one or two, and in other embodiments, the number of the elastic members 30 may also be three or more, as long as the elastic deformation of the elastic members 30 can drive the limiting member 20 to move up and down along the direction parallel to the axis L.

Referring to fig. 6, fig. 6 is a schematic structural diagram of the optical coupling element in the embodiment shown in fig. 1 of the present application. In some embodiments, the light coupling element 40 may be a sheet, plate or block structure. In the embodiment shown in fig. 6, the light coupling element 40 may be a sheet structure and configured as a light coupling flap. As shown in fig. 6, the optical coupler element 40 includes a signal acquisition portion 41 and a mounting portion 42 extending from an edge of the signal acquisition portion 41. The optical coupling element 40 can be mounted on the limiting member 20 through the mounting portion 42, and the signal acquiring portion 41 can acquire a detection signal indicating whether the test tube 90 at the scanning recognition position (not shown) is present.

In some embodiments, the mounting portion 42 is not connected to both edges of the signal obtaining portion 41 perpendicular to the preset direction. In some embodiments, the mounting portion 42 may be connected to a central position of an edge of the signal acquisition portion 41.

Specifically, two fifth mounting holes 421 and 422 are provided on the mounting portion 42, so that the optical coupling element 40, for example, the mounting portion 42, is fixedly mounted on the limiting member 20, for example, the second side portion 23, through the fifth mounting holes 421 and 422. Specifically, when assembling, fasteners, such as bolts (not shown), can be used to pass through the fifth mounting holes 421 and 422 one by one and be received in the fifth grooves 231 and 232, so that the optical coupling element 40, such as the mounting portion 42, can be fixedly mounted on the limiting member 20, such as the second side portion 23. Thus, when the first moving assembly 10 moves downward in a direction parallel to the axis L, the optical coupling element 40 may also move downward in a direction parallel to the axis L together with the limiting member 20, so that the signal acquiring portion 41 may acquire a detection signal of whether the test tube 90 at the scanning recognition position (not shown) is present. Alternatively, the scan identification location may be a test tube rack or other area to be detected. The following content of this application is introduced for the test-tube rack with scanning identification position. It is understood that the specific structure of the optical coupling element 40 may be other existing structures, and is not limited in this application.

Referring to fig. 5 and 7, fig. 7 is an exploded perspective view of the second motion assembly of the embodiment of fig. 1 of the present application. As shown in fig. 5 and 7, the second moving assembly 50 may include a second motor 51, a transmission member 52 connected to the second motor 51 and capable of penetrating through the limiting member 20, an actuating member 53 connected to the transmission member 52 and disposed at an end of the limiting member 20 far from the second motor 51, a guide member 54 disposed at one side of the transmission member 52 and connected to the second motor 51 and capable of penetrating through the limiting member 20, a second fixing member 55 connected to the second motor 51, and a mounting plate 56 connected to an end of the second fixing member 55. The elastic element 30 can be sleeved on the guiding element 54, so that the second moving element 50, for example, the second motor 51, can drive the elastic element 30 to be compressed or reset to generate elastic deformation, so as to provide an elastic force for the limiting element 20 to move up and down along a direction parallel to the axis L, and further drive the first moving element 10 to move up and down along the axis L.

Similar to the action of the first motor 11 in fig. 2, the second motor 51 can also provide a pivoting force for the second moving component 50, such as the transmission member 52, so that the second moving component 50 can compress or stretch the elastic member 30, such as the first elastic member 31 and the second elastic member 32, sleeved on the guide member 54, so as to be driven to generate an elastic deformation, thereby providing an elastic force for the limiting member 20 to move up and down along a direction parallel to the axis L, so as to drive the first moving component 10 to move up and down along a direction parallel to the axis L. Further, similar to the structure of the first motor 11, the second motor 51 may also include a second motor main body 511 and a second rotating shaft 512 disposed at an end of the second motor main body 511. An end of the second rotating shaft 512 away from the second motor body 511 is at least partially accommodated in the transmission member 52 to be in transmission connection with the transmission member 52, so that the second motor 51 can provide driving power for the transmission member 52, and then the elastic member 30, such as the first elastic member 31 and the second elastic member 32, sleeved on the guide member 54 is elastically deformed.

In some embodiments, the second motor 51 may further form a connection mode with the transmission member 52 to form a screw motor, and the specific structure thereof may be other existing structures, which is not described in detail.

Similarly, the end of the second motor body 511 may be provided with at least one sixth groove 5111, so that the second motor body 511 and the second fixing member 55 are fittingly coupled through the sixth groove 5111. Alternatively, the number of the sixth grooves 5111 is four and is distributed at the end of the second motor body 511 centering on the second rotating shaft 512. In assembling, fasteners, such as bolts (not shown), may be used to pass through the second fixing member 55 one by one, so that the second motor 51, such as the second motor main body 511, is securely mounted on the second fixing member 55. It is understood that the number of the sixth grooves 5111 can be adjusted according to the actual situation, for example, three or five grooves are also possible.

Referring to fig. 5, 7 and 8, fig. 8 is a cross-sectional view of a transmission member according to the embodiment of fig. 7. As shown in fig. 5, the transmission member 52 can penetrate through the second through hole 211 of the limiting member 20, so that the second moving component 50 can be connected to the limiting member 20. Specifically, the transmission 52 may be a screw rod, which may include a transmission body 521 and a second connection portion 522 extending from the transmission body 521 in a direction away from the second motor main body 511 and connected to the second rotating shaft 512. As shown in fig. 5 and 8, the transmission member body 521 may be a cylindrical structure, for example, a cylinder, and the surface thereof is provided with a thread. Optionally, the transmission member body 521 is a solid body. In an embodiment, the top of the second connecting portion 522 is provided with a seventh groove 5221, so that the second rotating shaft 512 can be partially received in the seventh groove 5221 of the second connecting portion 522, and further, the outer circumference of the second connecting portion 522 is further provided with a sixth mounting hole 5222, so that a fastener, such as a bolt (not shown), can pass through the sixth mounting hole 5222 to firmly mount the transmission member 52 on the second rotating shaft 512.

Specifically, the transmission member 52, such as the second connecting portion 522, is connected to the second motor 51, such as the second rotating shaft 512, so that the transmission member 52 can transmit the pivoting power provided by the second motor main body 511 to the actuating member 53 connected to the transmission member body 521, and the rotation motion of the transmission member 52 is converted into the linear motion of the actuating member 53 connected to the transmission member 52 by the threads 5211 provided on the surface of the transmission member body 521. It is understood that when the transmission member 52 is a screw, the specific structure thereof may be other existing structures, and is not limited in this application.

With continuing reference to fig. 5, 7 and 9, fig. 9 shows a cross-sectional view of the actuator of the embodiment of fig. 7 of the present application. As shown in fig. 5, the actuating member 53 is disposed on a side of the limiting member 20 away from the second connecting portion 522 of the transmission member 52 and is threadedly connected to the transmission member body 521. Specifically, the transmission body 521 can penetrate through the second through hole 211 of the limiting member 20, connect with the actuator 53 disposed at the end of the limiting member 20, and abut against the mounting plate 56. Alternatively, the actuator 53 may be a lead screw nut. As shown in fig. 5 and 9, the actuator 53 may have a plate-shaped structure, which may include a third connecting portion 531 and a boss 532 extending from the third connecting portion 531 toward the second motor main body 511. The boss 532 may be embedded in the second through hole 211, so that an end surface of the limiting member 20 away from the top 21 abuts against an end surface of the third connecting portion 531 of the actuating member 53, and the limiting member 20 may be connected to the transmission member 52 and the actuating member 53 in a matching manner.

Specifically, the third connection part 531 may have a rectangular parallelepiped structure, such as a rectangular parallelepiped or a square. In an embodiment, the third connecting portion 531 is further provided with two sixth through holes 5311 and 5312 respectively disposed at two opposite sides of the boss 532, so that the guide 54 can penetrate the sixth through holes 5311 and 5312. Similarly, the top of the boss 532 is also provided with a seventh through hole 5321, so that the transmission member 52 can sequentially penetrate through the second through hole 211 and the seventh through hole 5321 and abut against the mounting plate 56. In some embodiments, in order to match the central positions of the third through hole 212, the second through hole 211, and the fourth through hole 213, the central positions of the sixth through hole 5311, the seventh through hole 5321, and the sixth through hole 5312 may also be arranged on the same axis in sequence.

It is understood that, when the actuator 53 is a screw nut, the specific structure thereof may be other existing structures, and the present application is not limited thereto.

In some embodiments, the transmission member 52 and the execution member 53 may form a connection manner for fixing the lead screw nut, and the specific structure thereof may be other existing structures, and is not described in detail.

Referring to fig. 5 and 7 again, as shown in fig. 5, one end of the guiding element 54 is connected to the second motor 51, such as the second motor main body 511, the other end abuts against the actuating element 53, and the elastic element 30 is sleeved on the guiding element 54.

As shown in fig. 7, the guide 54 may include a first guide 541 disposed at one side of the second rotating shaft 512 and a second guide 542 disposed at the other side of the second rotating shaft 512 away from the first guide 541. The central axis of the first guiding element 541 and the central axis of the second guiding element 542 are parallel to each other, the first guiding element 541 is sleeved with the first elastic element 31, and the second guiding element 542 is sleeved with the second elastic element 32. Specifically, one end of the first guide 541 penetrates through the second fixing element 55 and is connected to one side of the second motor body 511, and the other end of the first guide 541, which is away from the second motor body 511, can penetrate through the third connecting portion 531 of the actuator 53 and can be partially accommodated in the sixth through hole 5311 of the actuator 53. Similarly, the second guiding element 542 is also connected to the first guiding element 541 in the same way, and is not described in detail. Alternatively, the first guide 541 and the second guide 542 may be guiding shafts with cylindrical structures, such as cylinders, but other cylindrical structures are also possible, as long as the first elastic member 31 and the second elastic member 32 can be respectively sleeved on the first guide 541 and the second guide 542. For example, the first and second guides 541 and 542 may be linear slide rails.

It is to be understood that while the guide 54 is shown as including two guides (i.e., the first guide 541 and the second guide 542), this is not required. In some embodiments, the guide 54 may include only one guide, or three or more guides, as long as the number of the elastic members 30 is matched.

Referring to fig. 7 again, as shown in fig. 7, the second fixing member 55 may include a top plate 551, a second side plate 552 extending from an edge of the top plate 551 in a direction away from the second motor body 511, and a second bottom plate 553 opposing to and spaced from the top plate 551. The top plate 551 is connected to the second motor body 511 of the second motor 51, and an end surface of the top plate 551 abuts against one end of the elastic member 30.

The top plate 551 may be a plate-like structure. Specifically, the structure may be a rectangular plate-like structure, and of course, the structure may also be in other shapes, such as a circular-like shape or other polygons, and the shape may be specifically adjusted according to the actual application. The top plate 551 may be provided with an eighth through hole 5511 penetrating the top plate 551 and a seventh mounting hole 5512 disposed at one side of the eighth through hole 5511. The second rotating shaft 512 can penetrate through the eighth through hole 5511 of the top plate 551 and is connected to the transmission member 52, so that an end of the second rotating shaft 512 away from the second motor main body 511 can be at least partially accommodated in the transmission member 52, and the second motor 51, for example, the second rotating shaft 512, can be in transmission connection with the transmission member 52. Alternatively, an end surface of the top plate 551 abuts against an end surface of the second motor main body 511, and a fastener, such as a bolt (not shown), may be used to pass through the seventh mounting hole 5512 on the top plate 551 and be received in the sixth groove 5111 on the second motor main body 511, so as to firmly mount the second motor 51, such as the second motor main body 511, on the top plate 551. It is understood that the seventh mounting hole 5512 may be plural. In an embodiment, the seventh mounting holes 5512 may be four and distributed around the eighth through hole 5511 as a center at the periphery of the seventh mounting hole 5512, so that the second motor 51, for example, the second motor main body 511 is securely mounted on the top plate 551. Of course, the number of the seventh mounting holes 5512 may also be specifically determined as required by the particular application.

In an embodiment, the top plate 551 further includes two ninth through holes 5513a and 5513b respectively disposed on opposite sides of the eighth through hole 5511, an eighth mounting hole 5514 disposed on one side of the ninth through hole 5513b and disposed on an edge of the top plate 551, and two ninth mounting holes 5515a and 5515b respectively disposed on opposite sides of the eighth mounting hole 5514. Wherein the axes of the ninth through holes 5513a and 5513b and the seventh mounting hole 5512 are parallel to each other. The first guide 541 and the second guide 542 can respectively pass through the ninth through holes 5513a and 5513b of the top plate 551, and are connected to the second motor body 511, and one ends of the first elastic element 31 and the second elastic element 32 sleeved on the first guide 541 and the second guide 542 are respectively abutted against an end surface of the top plate 551.

In some embodiments, the signal detection assembly 60 may include a first signal detection member 61 and an oppositely disposed second signal detection member 62. The signal detecting unit 60, for example, the second signal detector 62, can be fixedly mounted on the top plate 551 of the second fixture 55 through the eighth mounting hole 5514 and the two ninth mounting holes 5515a and 5515b.

As shown in fig. 7, the second side plate 552 may also be provided in a plate-like structure. In particular, the structure can be a similar rectangular plate structure. It may also be in other shapes such as trapezoid, ellipse, etc., and the shape may be changed according to the actual situation. Optionally, the second side plate 552 may be provided with a tenth through hole 5521 penetrating through the second side plate 552, wherein the tenth through hole 5521 may also be shaped like a rectangle. Specifically, the tenth through hole 5521 is configured such that the second bottom plate 553 may be extended from an end of the tenth through hole 5521 away from the top plate 551, thereby simplifying the overall structure of the second fixing piece. In an embodiment, the end of the second bottom plate 553 far from the top plate 551 is further provided with two tenth mounting holes 5522a, 5522b for mounting the test tube test reading device 100 in the embodiment of the present application on other devices of the sample analyzer 200 (as shown in fig. 12). In some embodiments, as shown in fig. 7, the tenth mounting holes 5522a, 5522b may be notches formed by recessing from a side of the second side plate 552 away from the top plate 551 in a direction close to the top plate 551, so as to facilitate the access of the test tube inspection reader 100 in the embodiment of the present application, for example, when the test tube inspection reader 100 needs to be disassembled, the test tube inspection reader 100 can be disassembled by unscrewing the fasteners without disassembling the fasteners. Specifically, the two tenth mounting holes 5522a, 5522b may have a kidney-like hole shape to eliminate errors during the process of assembling.

As shown in fig. 7, a second bottom plate 553 is spaced opposite the top plate 551 and is connected to the second side plate 552. Further, the second bottom plate 553 may be connected with a sidewall of the tenth through hole 5521 remote from the top plate 551, and adjacent to the two tenth mounting holes 5522a, 5522b on the second side plate 552. Similarly, the second bottom plate 553 may also be a similar rectangular plate structure, and of course, it may also be other shapes such as trapezoid, ellipse, etc., and the shape may be changed according to the actual situation.

Alternatively, the second bottom plate 553 may be opened with an eleventh through hole 5531 penetrating the second bottom plate 553 and two twelfth through holes 5532a, 5532b respectively disposed at opposite sides of the eleventh through hole 5531. The transmission member 52, such as the transmission member body 521, can penetrate through the eleventh through hole 5531 of the second bottom plate 553 and abut against the mounting plate 56. The first guide 541 and the second guide 542 may penetrate the twelfth through holes 5532a and 5532b, respectively, and abut against the mounting plate 56. In some embodiments, in order to match the central positions of the sixth through hole 5311, the seventh through hole 5321, and the sixth through hole 5312, the central positions of the twelfth through hole 5532a, the eleventh through hole 5531, and the twelfth through hole 5532b may also be aligned on the same axis and in sequence. Optionally, two thirteenth through holes 5533a, 5533b may be further disposed on the second bottom plate 553, wherein the axes of the two thirteenth through holes 5533a, 5533b are parallel to the axes of the two twelfth through holes 5532a, 5532b, respectively. Specifically, when the second moving member 50 is assembled and disassembled, the two thirteenth through holes 5533a and 5533b are configured to allow an assembling and disassembling tool to be inserted into the two thirteenth through holes 5533a and 5533b, so as to assemble and disassemble the second moving member 50. In an embodiment, the number of the sixth grooves 5111 is four, and the sixth grooves 5111 are distributed at the end of the second motor main body 511 with the second rotating shaft 512 as the center, when the second moving component 50, such as the second motor 51, is disassembled, the disassembling tool can be inserted into the two fifth through holes 214 and 215 of the limiting member 20 to disassemble and assemble the fasteners in the two sixth grooves 5111 near the end of the first side portion 22, and similarly, the disassembling tool can be inserted into the two thirteenth through holes 5533a and 5533b of the second bottom plate 553 to disassemble and assemble the fasteners in the two sixth grooves 5111 far from the end of the first side portion 22.

Referring to fig. 7 again, the mounting plate 56 is disposed on a side of the second bottom plate 553 of the second fixing member 55 away from the top plate 551. The end surfaces of the mounting plates 56 abut against the end surfaces of the second bottom plate 553 near the two tenth mounting holes 5522a, 5522b. Specifically, the whole mounting plate 56 may also be a plate-shaped structure, and the shape of the structure may be adjusted according to the actual application condition, which is not described in detail. Optionally, the mounting plate 56 is further provided with a first connection hole 561, an eleventh mounting hole 562 disposed on one side of the first connection hole 561 and located at an edge of the mounting plate 56, and two twelfth mounting holes 563a and 563b disposed on opposite sides of the eleventh mounting hole 562.

In some embodiments, a signal detection assembly 60, such as a first signal detection member 61, may be mounted on the mounting plate 56. After sequentially passing through the second through hole 211 of the limiting member 20 and the seventh through hole 5321 of the actuating member 53, the transmission member body 521 of the transmission member 52 can further pass through the first connecting hole 561 of the mounting plate 56 and abut against the mounting plate 56, so that the transmission member 52 can be matched with the limiting member 20, the actuating member 53 and the first signal detecting member 61 of the signal detecting member 60 mounted on the mounting plate 56. The first signal detecting member 61 may pass through the eleventh mounting hole 562 and the two twelfth mounting holes 563a and 563b to be fixedly mounted on the mounting plate 56 of the second moving assembly 50. When the second moving assembly 50 drives the limiting member 20 to move up and down along the direction parallel to the axis L, the first signal detecting member 61 mounted on the mounting plate 56 can determine whether the test tube 90 exists at the scanning identification position according to the detection signal of the optical coupling element 40.

Referring to fig. 1, 5 and 10 together, fig. 10 is a schematic structural diagram of a signal detection element in the embodiment shown in fig. 1. As shown in fig. 1, 5 and 10, the signal detecting assembly 60 may include a first signal detecting member 61 disposed on the mounting plate 56 and a second signal detecting member 62 disposed on the top plate 551 and opposite to the first signal detecting member 61.

Optionally, the first signal detecting part 61 and the second signal detecting part 62 may be one of a photoelectric switch, a reflective optical coupler, a micro switch, etc., as long as the requirement of obtaining the detection signal of the test tube 90 is satisfied, and the specific structure thereof may be other existing structures, which is not limited in this application.

Specifically, as shown in fig. 10, the first signal detecting part 61 may include two first stoppers 611 disposed parallel to each other, a first connecting body 612 extending from the two first stoppers 611 toward a direction approaching the mounting plate 56, and two second stoppers 613 disposed at one side of the first connecting body 612 and disposed parallel to each other. Wherein, the two first blocking parts 611 may penetrate the eleventh mounting hole 562 on the mounting plate 56. The end surfaces of the first connecting body 612 facing the two first blocking parts 611 can abut against the end surface of the mounting plate 56, and the two second blocking parts 613 are disposed opposite to the two first blocking parts 611. Further, the two second blocking portions 613 are disposed at an interval from each other, and the two first blocking portions 611 are disposed at an interval from each other, so that when the optical coupler element 40 moves downward along the direction parallel to the axis L along with the limiting member 20, the signal obtaining portion 41 can insert into the interval between the two first blocking portions 611 towards one end of the first signal detecting member 61 during the movement towards the two first blocking portions 611 of the first signal detecting member 62, so as to obtain a detection signal of whether the test tube 90 exists on the test tube rack, so that the first signal detecting member 61 can determine whether the test tube 90 exists according to the detection signal obtained by the optical coupler element 40. Namely: if the signal obtaining portion 41 obtains a detection signal before embedding the interval between the two first blocking portions 611 toward one end portion of the first signal detecting member 61, the obtained detection signal is a detection signal of the test tube 90, so that the first signal detecting member 61 determines that the test tube 90 exists on the test tube rack according to the detection signal, at this time, the limiting member 20 does not drive the optical coupling element 40 to continue to move downward along the direction parallel to the axis L. If the signal acquisition part 41 acquires a detection signal towards one end of the first signal detection member 61 in the interval between the two first blocking parts 611, the detection signal of the test tube 90 is not acquired, and at this time, the limiting part 20 does not drive the optical coupling element 40 to move downwards along the direction parallel to the axis L.

Optionally, as shown in fig. 10, the first connecting body 612 may further include two second connecting holes 612a and 612b respectively disposed at two sides of the two first blocking portions 613, so that the first signal detecting member 61 may be fixedly mounted on the mounting plate 56 of the second fixing member 55 by the two second connecting holes 612a and 612b being in fit connection with the two twelfth mounting holes 563a and 563b of the mounting plate 56.

It will be appreciated that the first signal detection member 61 may cooperate with the light coupling element 40 as a detection assembly, which may be used to obtain a detection signal and determine whether the cuvette 90 is present or not according to the detection signal, i.e.: the detecting assembly may automatically detect the presence or absence of the test tube 90 according to the reciprocating movement of the first moving assembly 10 in the preset direction.

Similarly, the structure of the second signal detection part 62 is the same as that of the first signal detection part 61, and is not described in detail. Two third blocking portions 621 are disposed adjacent to the top plate 551, and the fourth blocking portion 623 is located at a side of the second connecting body 622 away from the third blocking portions 621. Specifically, the two third blocking portions 621 of the second signal detector 62 may penetrate through the eighth mounting hole 5514 on the top plate 551, and end surfaces of the second connector 622 facing the two third blocking portions 621 may abut on end surfaces of the top plate 551.

Further, the two third blocking portions 621 are disposed at an interval therebetween, and an interval is also disposed between the two fourth blocking portions 623, so that when the optical coupling element 40 moves upward along the direction parallel to the axis L along with the limiting member 20, the signal obtaining portion 41 can insert into the interval between the two third blocking portions 621 toward the other end portion of the second signal detecting member 62 during the movement of the signal obtaining portion 41 toward the two third blocking portions 621 of the second signal detecting member 62, so as to eliminate an accumulated error of the test tube detecting and reading device 100 in the embodiment of the present application every time one working cycle is completed.

FIG. 11 is a schematic view of the test tube testing and reading apparatus according to the embodiment of FIG. 1 of the present application. As shown in fig. 11, in some embodiments, the test tube detection and reading device 100 may further include a code scanning member 70 for scanning and reading a bar code (not shown) of the test tube 90. Alternatively, the specific structure of the code scanning member 70 may be other existing structures, and the present application is not limited as long as the mechanism that can be used for performing code scanning reading and completing scanning identification on the test tube 90 satisfies the condition. It is understood that although the code scanning member 70 is shown as a position in fig. 11, this is not necessary, and the position of the code scanning member 70 can be flexibly set according to practical situations as long as the test tube 90 can be scanned in the scanning area, and the position is not particularly limited in this application.

Alternatively, during operation of the test tube test reader 100 in the embodiment shown herein, the controller 80 may be used to initiate activation of the apparatus described herein to complete a work cycle. Specifically, the controller 80 can be used to control the activation of the second moving assembly 50, such as the second motor 51, so as to drive the elastic element 30 to generate elastic deformation and generate elastic force, so as to drive the limiting element 20 to move up and down along the direction parallel to the axis L, and further drive the first moving assembly 10 to move up and down along the direction parallel to the axis L. The controller 80 is further configured to control activation of the first moving assembly 10, such as the first motor 11, to drive the first moving assembly 10 to rotate in the predetermined plane when detecting the presence of the test tube 90, so as to drive the test tube 90 to rotate with the first moving assembly 10 in the predetermined plane. Similarly, the specific structure of the controller 80 may be other existing structures, and the present application is not limited thereto as long as the specific structure can be used to control the first moving assembly 10 to rotate in the predetermined plane and control the second moving assembly 50 to drive the limiting member 20 to drive the first moving assembly 10 to move up and down along the direction parallel to the axis L.

As shown in fig. 11, the test tube 90 detected by the device of the present application may include a test tube body 91, a test tube cap 92 covering the test tube body 91, and a barcode adhered to the test tube 90. The test tube cap 92 can contact with the rotating base 121 of the rotating member 12, when the first moving assembly 10 is driven to move downwards in a direction parallel to the axis L, the rotating base 121 is connected with the test tube cap 92, and due to the fact that the rotating base 121 is subjected to downward elastic force of the elastic member 30, friction force exists between the end face of the rotating base 121 and the end face of the test tube cap 92, so that the test tube cap 92 is pressed, the first moving assembly 10 can drive the test tube 90 to rotate in a preset plane, and until a barcode on the test tube 90 rotates to a scanning area of the barcode scanning member 70 for scanning and identifying.

Alternatively, the test tubes 90 may be different models of test tubes, e.g., having different heights. In an embodiment, the height of the test tube 90 is H1, and the test tube is of a type having a larger height, and the amount of deformation of the first and second elastic members 31 and 32 is larger, so that the rotating base 121 is subjected to a larger downward elastic force, and the pressure applied to the test tube cap 92 is larger, so that the rotating base 121 presses the test tube cap 92 more firmly. In another embodiment, the height of the test tube 90 is H2, wherein H2 is less than H1, that is, the test tube 90 is a test tube type with a small height, and the amount of deformation of the first elastic member 31 and the second elastic member 32 is small, so that the amount of deformation only needs to be enough to make the rotating base 121 firmly press the test tube cap 92.

The operation of the test tube test reading device in the embodiment of the present application will be described in detail with reference to the test tube test reading device in fig. 1 or fig. 11.

The controller 80 is started, at this time, the second motor 51 is started, so that the second motor 51 provides a pivot power for the transmission member 52, the transmission member 52 then transmits the provided pivot power to the executing member 53 cooperatively connected with the transmission member 52, and the first elastic member 31 and the second elastic member 32 respectively sleeved on the first guide member 541 and the second guide member 542 are driven to be compressed or reset, so that the first elastic member and the second elastic member are driven to generate elastic deformation or restore the original state, so as to drive the limiting member 20 to move up and down along a direction parallel to the axis L, and further drive the first moving assembly 10 connected with the limiting member 20, for example, the first side portion 22, to move up and down along a direction parallel to the axis L.

When the rotating base 121 presses the test tube cap 92, the controller 80 is started again, and at this time, the first motor 11 is started to drive the first moving assembly 10 to rotate in the preset plane, so as to drive the test tube 90 to rotate in the preset plane until the barcode on the test tube 90 rotates to the scanning area of the barcode scanning member 70 for scanning and identification, the controller 80 is turned off, and the first moving assembly 10 stops rotating. After the test tube 90 is scanned and identified, the controller 80 is started again, and at this time, the second motor 51 is started, so that the second motor 51 provides the pivoting force for the transmission member 52 again, and the actuating member 53 is driven to move upwards along the direction parallel to the axis L, that is: the actuating member 53 moves in a direction parallel to the axis L toward the top plate 551 on the second fixing member 55, at this time, the limiting member 20 connected to the actuating member 53 moves upward in a direction parallel to the axis L to drive the first elastic member 31 and the second elastic member 32 to return and provide an elastic force for the limiting member 20 to move upward in a direction parallel to the axis L, so that the limiting member 20 is driven to drive the first moving assembly 10 to move upward in a direction parallel to the axis L until the first elastic member 31 and the second elastic member 32 return to the original state, and the limiting member 20 moves upward in a direction parallel to the axis L to the initial position, and the controller 80 is turned off.

If the signal acquisition unit 41 of the optical coupler element 40 acquires a detection signal toward one end of the first signal detection member 61 in the interval between the two first stoppers 611, a detection signal indicating that the test tube 90 is not present is acquired, and the first signal detection member 61 determines that the test tube 90 is not present on the test tube rack based on the detection signal of the optical coupler element 40. At this time, the controller 80 is started again, at this time, the second motor 51 is started, so that the second motor 51 provides a pivoting force for the transmission member 52 again, the actuating member 53 is driven to move upward along a direction parallel to the axis L, the first elastic member 31 and the second elastic member 32 are driven to reset, and an elastic force which moves upward along a direction parallel to the axis L is provided for the limiting member 20, at this time, the limiting member 20 drives the first moving assembly 10 to move upward along a direction parallel to the axis L until the first elastic member 31 and the second elastic member 32 reset to the original state, and the limiting member 20 moves upward along a direction parallel to the axis L to the initial position, and the controller 80 is turned off. Further, when the limiting member 20 moves upward to the initial position in the direction parallel to the axis L, the other end of the signal acquiring portion 41 facing the second signal detecting member 62 may be embedded in the interval between the two third blocking portions 621 of the second signal detecting member 62, thereby eliminating the accumulated error of the cuvette test-tube detection-reading apparatus 100.
