Description

Technical Field

[0001] The present application relates to the field of rotary code scanning, and in particular to a rotary clamping structure and a rotary scanning device for test tube identification codes. Background Art

[0002] The conventional rotating code scanning device scans the object by rotating the object. Taking the rotating code scanning device of a test tube as an example, it adopts the following two implementation methods.

[0003] One implementation method is to use three motors, where the first motor drives the active wheel to approach the test tube, the second motor drives the passive wheel to approach the test tube, and the third motor drives the active wheel to rotate to drive the test tube. That is, two motors are used to control the active wheel and the passive wheel to approach or move away from the test tube, and another motor is used to control the active wheel to rotate. A total of three motors are used, which has problems such as high material cost, complex coordination and high failure rate.

[0004] Another implementation method is to use two motors. For example, the Chinese patent document with application publication number CN108268809A discloses a test tube rotating mechanism and a test tube rotating code scanning device. The test tube rotating mechanism includes: a bracket, a driving part, a transmission part and a limiting part respectively fixed on the bracket and with the axis in the vertical direction; the limiting part is tangent to the test tube at two first tangent points, and the transmission part is tangent to the test tube at a second tangent point. The second tangent point and the two first tangent points are located in the same horizontal plane and the connecting line forms an isosceles triangle. The second tangent point is located at the vertex angle of the isosceles triangle; the transmission part rotates under the drive of the driving part and rubs the test tube at the second tangent point. The test tube rotates passively under the action of friction and drives the limiting part to rotate by rubbing the limiting part at the first tangent point.

[0005] Similarly, a Chinese patent document with authorization announcement number CN209132780U discloses an automatic rotating identification scanning mechanism, including: a tube pulling mechanism, a rotating mechanism and a scanning mechanism arranged on a main substrate; the tube pulling mechanism and the rotating mechanism are connected on the same axis; the tube pulling mechanism pulls test tubes of different diameters on a test tube rack close to the rotating mechanism and clamps them at a tube clamping station, the rotating mechanism rotates to drive the clamped test tube to rotate, and the scanning mechanism is located on one side of the test tube to scan the test tube identification that rotates into the identification area.

[0006] The technical solutions disclosed in the above two patent documents are that only one motor is used to control the driving wheel to approach or move away from the test tube, and another motor is used to control the driving wheel to rotate. This method easily causes the test tube to be very close to the passive wheel during operation, and there is a high probability that the test tube will touch the passive wheel uncontrollably, and may even cause the test tube to rupture, thereby causing a risk of use.

[0065] The present application discloses a rotating clamping structure and a rotating scanning device for test tube identification codes, which include some or all of the technical features of the following embodiments; that is, the rotating clamping structure and the rotating scanning device for test tube identification codes include some or all of the following structures. In one embodiment of the present application, a rotating clamping structure includes a clamping structure assembly, a passive wheel structure assembly and a driving wheel structure assembly: the passive wheel structure assembly and the driving wheel structure assembly are both arranged on the clamping structure assembly, and the clamping structure assembly is provided with a first motor for adjusting the relative distance between the passive wheel structure assembly and the driving wheel structure assembly so that the passive wheel structure assembly and the driving wheel structure assembly jointly clamp the test tube to be scanned; the driving wheel structure assembly is provided with a second motor for driving the test tube to be scanned to rotate when the passive wheel structure assembly and the driving wheel structure assembly jointly clamp the test tube to be scanned. The above-mentioned rotary clamping structure uses only two motors, one motor controls the relative distance between the passive wheel structure component and the active wheel structure component, and the other motor controls the rotation of the active wheel, which fundamentally eliminates the possibility of the test tube to be scanned touching the passive wheel structure component uncontrolled, and can achieve clamping and loosening actions in a smaller volume design, and has the advantages of simple structure and convenient application. The scope of application includes but is not limited to barcode scanning of sample tubes. The rotary clamping structure and the test tube identification code rotary scanning device are described in detail below in conjunction with Figures 1 to 8.

[0066] In one embodiment, a rotating clamping structure 100 is shown in Figure 1, which includes a clamping structure assembly 200, a passive wheel structure assembly 300 and a driving wheel structure assembly 400: the passive wheel structure assembly 300 and the driving wheel structure assembly 400 are both arranged on the clamping structure assembly 200. In combination with Figures 5 and 6, the passive wheel structure assembly 300 and the driving wheel structure assembly 400 are used to jointly form a rotating code scanning position 500, and the clamping structure assembly 200 is used to adjust the relative distance 260 between the passive wheel structure assembly 300 and the driving wheel structure assembly 400, so that the passive wheel structure assembly 300 and the driving wheel structure assembly 400 can jointly clamp the test tube 900 to be scanned.

[0067] In one embodiment, as shown in FIG. 2 , the clamping structure assembly 200 is provided with a first motor 210, and the first motor 210 is used to adjust the relative distance 260 between the passive wheel structure assembly 300 and the active wheel structure assembly 400, so that the passive wheel structure assembly 300 and the active wheel structure assembly 400 can jointly clamp the test tube 900 to be scanned; and the active wheel structure assembly 400 is provided with a second motor 420, which is used to drive the test tube 900 to be scanned to rotate when the passive wheel structure assembly 300 and the active wheel structure assembly 400 jointly clamp the test tube 900 to be scanned. With such a structural design, the rotating clamping structure 100 can cooperate with the scanner 800 to scan the code at the rotating scanning position 500 of the rotating clamping structure 100 using only two motors, thereby eliminating the possibility of the test tube 900 to be scanned touching the passive wheel structure assembly 300 in an uncontrolled manner, and has the advantages of simple structure, compact size, and convenient application.

[0068] In order to facilitate accurate control of the positions of the passive wheel structure assembly 300 and the active wheel structure assembly 400 relative to the clamping structure assembly 200 so as to accurately clamp the test tube 900 to be scanned, in one embodiment, the passive wheel structure assembly 300 and the active wheel structure assembly 400 are both slidably disposed on the clamping structure assembly 200; as shown in Figures 2 and 3, the passive wheel structure assembly 300 is slidably disposed on the clamping structure assembly 200 via a first slider 231, and the active wheel structure assembly 400 is slidably disposed on the clamping structure assembly 200 via a second slider 232. In this embodiment, the clamping structure assembly 200 is also provided with an abutment member 240 and an elastic member 250; the abutment member 240 is used to continuously abut the passive wheel structure assembly 300 and the driving wheel structure assembly 400 at the same time to avoid accidents caused by sudden loosening; the elastic member 250 is used to elastically tighten the passive wheel structure assembly 300 and the driving wheel structure assembly 400 so that the passive wheel structure assembly 300 and the driving wheel structure assembly 400 maintain an abutment relationship with the abutment member 240, and the elastic force of the elastic member 250 acts on the passive wheel structure assembly 300 and the driving wheel structure assembly 400, forming an abutment pressure on the abutment member 240.

[0069] Exemplarily, in one embodiment, as shown in Figures 2 and 3, the passive wheel structure assembly 300 and the driving wheel structure assembly 400 are both slidably arranged on the clamping structure assembly 200; the two ends of the elastic member 250 are respectively connected to the passive wheel structure assembly 300 and the driving wheel structure assembly 400 to pull the passive wheel structure assembly 300 and the driving wheel structure assembly 400 to press the abutment 240; the outer peripheral edge 241 of the abutment 240 has alternating long sides 242 and short sides 243; the output shaft of the first motor 210 is connected to the abutment 240, and the first motor 210 is used to drive the abutment 240 to rotate so that the outer peripheral edge 241 continuously and simultaneously abuts against the passive wheel structure assembly 300 and the driving wheel structure assembly 400, and the relative distance 260 between the passive wheel structure assembly 300 and the driving wheel structure assembly 400 is adjusted under the action of the long sides 242 and the short sides 243. With such a structural design, when the outer peripheral edge 241 abuts the passive wheel structure assembly 300 and the driving wheel structure assembly 400 with the long side 242, the relative distance 260 between the passive wheel structure assembly 300 and the driving wheel structure assembly 400 is relatively large, and the test tube 900 to be scanned can be easily placed at this time; when the outer peripheral edge 241 abuts the passive wheel structure assembly 300 and the driving wheel structure assembly 400 with the short side 243, the relative distance 260 between the passive wheel structure assembly 300 and the driving wheel structure assembly 400 is relatively small, and at this time the passive wheel structure assembly 300 cooperates with the driving wheel structure assembly 400 to jointly clamp the test tube 900 to be scanned.

[0070] In one embodiment, when the passive wheel structural assembly 300 and the active wheel structural assembly 400 are both pressed against the long side 242, the passive matching structure 380 of the passive wheel structural assembly 300 and the active wheel 430 of the active wheel structural assembly 400 have a maximum spacing; when the passive wheel structural assembly 300 and the active wheel structural assembly 400 are both pressed against the short side 243, the passive matching structure 380 of the passive wheel structural assembly 300 and the active wheel 430 of the active wheel structural assembly 400 have a minimum spacing and jointly clamp the test tube 900 to be scanned. Such a structural design is conducive to transferring the test tube 900 to be scanned and clamping the test tube 900 to be scanned, so as to cooperate with other structural parts to rotate the test tube 900 to be scanned.

[0071] In the embodiment shown in FIG3 , the elastic member 250 is a spring, and the two ends of the spring are respectively connected to the first slider 231 and the second slider 232; or the two ends of the spring can also be respectively connected to the main bracket 410 of the active wheel structure assembly 400 and the passive bracket 310 of the passive wheel structure assembly 300. Alternatively, in other embodiments, the elastic member 250 can also be a spring block. The embodiments of the present application do not impose additional restrictions on the specific shape and specifications of the spring or spring block, and only need to be able to cooperate with the abutment member 240 to continuously and simultaneously abut the passive wheel structure assembly 300 and the active wheel structure assembly 400.

[0072] In one embodiment, the outer peripheral edge 241 is alternately provided with at least one group of the long side portions 242 and the short side portions 243; specifically, the alternating long side portions 242 and short side portions 243 can be a long side portion 242 and a short side portion 243 as a group, which are continuously alternated by rotation; there can also be two or more groups of the long side portions 242 and the short side portions 243, which are continuously alternated group by group by rotation; each alternation completes a looseness or tightness conversion.

[0073] In one embodiment, as shown in FIG. 2 and FIG. 3 , the clamping structure assembly 200 is further provided with a fixing plate 220 and a guide rail 230, and the first motor 210 and the guide rail 230 are respectively fixedly arranged on the fixing plate 220; and the passive wheel structure assembly 300 is slidably arranged on the guide rail 230 through a first slider 231, and the active wheel structure assembly 400 is slidably arranged on the guide rail 230 through a second slider 232. Such a structural design is conducive to accurately controlling the positions of the passive wheel structure assembly 300 and the active wheel structure assembly 400, and ensuring that the test tube 900 to be scanned is clamped in place before rotating.

[0074] In order to keep the passive wheel structure assembly 300 and the driving wheel structure assembly 400 in contact with the abutment member 240 at the same time, in one embodiment, when the abutment member 240 is rotating, the outer peripheral edge 241 is continuously and simultaneously tangent to the surface of the passive wheel structure assembly 300 and the driving wheel structure assembly 400; in one embodiment, the cross section of the outer peripheral edge 241 is elliptical or track-shaped, or the cross section of the outer peripheral edge 241 is composed of two arcs with different diameters and a smooth connecting line therebetween, and illustratively, the smooth connecting lines between the two arcs with different diameters are two straight lines. In one embodiment, as shown in FIG4 , the abutment member 240 includes an elliptical cam and an ellipsoid; in combination with FIG2 , it can be seen that when the abutment member 240 is rotating, the outer peripheral edge 241 is continuously and simultaneously abutted against the passive wheel structure assembly 300 and the driving wheel structure assembly 400, and the outer peripheral edge 241 is tangent to the surface of the passive wheel structure assembly 300 and the driving wheel structure assembly 400, respectively. Such a structural design is conducive to always maintaining the abutting relationship between the passive wheel structural assembly 300 and the driving wheel structural assembly 400 and the abutting member 240 at the same time.

[0075] In one of the embodiments, as shown in FIG. 2 and FIG. 3, in addition to the second motor 420, the driving wheel structure assembly 400 is further provided with a main support 410, a driving wheel 430 and a driving shaft 440; the main support 410 is arranged on the clamping structure assembly 200, and the second motor 420 is arranged on the main support 410; illustratively, the second motor 420 is fixedly arranged on the main support 410, or the second motor 420 is detachably arranged on the main support 410, and the remaining embodiments are similar and will not be described in detail. The driving wheel 430 is mounted on the driving shaft 440, and the output end of the second motor 420 is connected to the driving shaft 440. The second motor 420 is used to drive the driving wheel 430 to rotate when the driving wheel 430 cooperates with the passive wheel structure assembly 300 to jointly clamp the test tube 900 to be scanned, so as to drive the test tube 900 to be scanned to rotate. With such a structural design, the rotating clamping structure 100 uses only two motors, one motor controls the relative distance 260 between the passive wheel structure assembly 300 and the active wheel structure assembly 400, and the other motor controls the rotation of the active wheel, thereby fundamentally eliminating the possibility of the test tube 900 to be scanned touching the passive wheel structure assembly 300 in an uncontrolled manner.

[0076] In one of the embodiments, the output end of the second motor 420 is used as the driving shaft 440; or, the axial direction of the driving shaft 440 is parallel to the rotating shaft 600 of the test tube 900 to be scanned; or, the axial direction of the driving shaft 440 is parallel to the axial direction of the output shaft of the first motor 210. Or, in one of the embodiments, the axial direction of the driving shaft 440 is parallel to the rotating shaft 600 of the test tube 900 to be scanned, and the axial direction of the driving shaft 440 is parallel to the axial direction of the output shaft of the first motor 210. The rest of the embodiments are similar and will not be described in detail. Such a structural design is conducive to ensuring that the rotation direction of the test tube 900 to be scanned, that is, the rotation direction, is consistent with the rotation direction of the driving shaft 440, that is, consistent with the rotation direction of the driving wheel 430, thereby improving the accuracy of the rotation control and also conducive to protecting the test tube 900 to be scanned. It should be noted that in the experiment, even if the rotation direction of the test tube 900 to be scanned is inconsistent with the rotation direction of the active shaft 440 or even has a certain deviation, as long as the deviation is not too large, the rotational scanning of the test tube identification code can be achieved, but there is a certain risk of use.

[0077] In one embodiment, as shown in FIG. 2 and FIG. 3 , the passive wheel structure assembly 300 is provided with a passive bracket 310 and a passive matching structure 380; the passive bracket 310 is movably arranged on the clamping structure assembly 200, and the passive matching structure 380 is arranged on the passive bracket 310; the output shaft of the first motor 210 is connected to the passive bracket 310, and is used to adjust the position of the passive bracket 310, so as to adjust the relative distance 260 between the passive matching structure 380 and the active wheel 430. Exemplarily, the passive bracket 310 is slidably arranged on the clamping structure assembly 200 or its fixing plate 220. By adjusting the relative distance 260 between the passive matching structure 380 and the active wheel 430 through the first motor 210, the relative distance 260 between the passive wheel structure assembly 300 and the active wheel structure assembly 400 can be controlled by one motor, so that actions such as clamping and releasing can be realized in a smaller volume design.

[0078] In this embodiment, the passive wheel structure assembly 300 is further provided with a mounting shaft 340 and a bearing 320 thereof, wherein the mounting shaft 340 is connected to the passive bracket 310; the output shaft of the first motor 210 is connected to the bearing 320, and is used to adjust the position of the bearing 320, and the passive bracket 310 is driven to move by the mounting shaft 340 to adjust the relative distance 260 between the passive matching structure 380 and the active wheel 430. Such a structural design is conducive to the outer peripheral edge 241 being continuously tangent to the surfaces of the passive wheel structure assembly 300 and the active wheel structure assembly 400 at the same time when the abutment member 240 is rotating.

[0079] In one embodiment, the passive matching structure 380 includes a passive wheel 330, a bracket 350, a passive shaft 360 and a mounting bracket 370. The mounting bracket 370 is arranged on the passive bracket 310. For example, the mounting bracket 370 is fixedly arranged on the passive bracket 310, or the mounting bracket 370 is detachably arranged on the passive bracket 310. The remaining embodiments are similar and will not be described in detail. The passive wheel 330 is rotatably arranged on the bracket 350 through the passive shaft 360. The bracket 350 is connected to the mounting bracket 370 to make the axial direction of the passive shaft 360 parallel to the axial direction of rotation of the active wheel 430. In this embodiment, the number of the passive wheel 330, the passive shaft 360 and the bracket 350 is a pair. Further, in one embodiment, the bracket 350 and the mounting bracket 370 are integrally arranged. Furthermore, in one embodiment, the passive support 310, the bracket 350 and the mounting support 370 are integrally arranged. With such a structural design, when the passive wheel structural assembly 300 and the active wheel structural assembly 400 jointly clamp the test tube 900 to be scanned, only a second motor 420 is needed to control the rotation of the active wheel 430. Since the active wheel 430 and the passive wheel 330 jointly clamp the test tube 900 to be scanned, the active wheel 430 drives the test tube 900 to be scanned to rotate, and the passive wheel 330 can follow and rotate around the passive axis 360. The test tube 900 to be scanned rotates to a certain position, which is the rotating scanning position 500. At this time, the identification code on the test tube 900 to be scanned can be recognized by the scanner 800.

[0080] For the embodiment in which the passive wheel 330 is not provided, the passive cooperation structure 380 can adopt a structure such as a ball groove or a sliding groove, and clamp the test tube 900 to be scanned together with the active wheel 430 through rolling cooperation or sliding cooperation. In the state of clamping the test tube 900 to be scanned together with the active wheel 430, the active wheel 430 drives the test tube 900 to be scanned to rotate, and the passive cooperation structure 380 does not limit the rotation of the test tube 900 to be scanned or cooperates with the rotation of the test tube 900 to be scanned.

[0081] The following is an example of the rotary clamping structure 100, which is further described in conjunction with Figures 1 to 8. In one embodiment, the clamping structure assembly 200 is provided with a first motor 210, a fixed plate 220, a guide rail 230, an abutment 240 and an elastic member 250, wherein the first motor 210 and the guide rail 230 are respectively fixedly arranged on the fixed plate 220; the output shaft of the first motor 210 is connected to the abutment 240, and the outer peripheral edge 241 of the abutment 240 has alternating long sides 242 and short sides 243; illustratively, the first motor 210 is used to drive the abutment 240 to rotate, so that the long sides 242 and the short sides 243 of the outer peripheral edge 241 alternately and simultaneously abut against the bearing 320 of the passive wheel structure assembly 300 and the main bracket 410 of the active wheel structure assembly 400, thereby realizing the coordinated clamping and loosening of the passive wheel structure assembly 300 and the active wheel structure assembly 400 through the first motor 210.

[0082] The driving wheel structural assembly 400 is provided with a main support 410, a second motor 420, a driving wheel 430 and a driving shaft 440; the main support 410 is slidably arranged on the guide rail 230 through a second slider 232, and the second motor 420 is arranged on the main support 410; the driving wheel 430 is installed on the driving shaft 440, and the output end of the second motor 420 is connected to the driving shaft 440. The second motor 420 is used to drive the driving wheel 430 to rotate when the driving wheel 430 cooperates with the passive wheel structural assembly 300 to jointly clamp the test tube 900 to be scanned, so as to drive the test tube 900 to be scanned to rotate.

[0083] The passive wheel structural assembly 300 is provided with a passive bracket 310, a bearing 320, a mounting shaft 340 and a passive matching structure 380. The passive bracket 310 is slidably arranged on the guide rail 230 through the first slider 231; the mounting shaft 340 is inserted into the bearing 320. The passive matching structure 380 includes a passive wheel 330, a bracket 350, a passive shaft 360 and a mounting bracket 370. The mounting bracket 370 is arranged on the passive bracket 310. The passive wheel 330 is rotatably arranged on the bracket 350 through the passive shaft 360. The bracket 350 is connected to the mounting bracket 370 to make the axial direction of the passive shaft 360 parallel to the axial direction of the active wheel 430.

[0084] The two ends of the elastic member 250 are respectively connected to the first slider 231 and the second slider 232, or are respectively connected to the main bracket 410 and the passive bracket 310, and the outer peripheral edge 241 abuts against the main bracket 410 and the bearing 320 at the same time; the installation shaft 340 is connected to the passive bracket 310, and the first motor 210 is used to adjust the position of the bearing 320, and the passive bracket 310 is driven to move through the installation shaft 340 to adjust the relative distance 260 between the passive wheel 330 and the active wheel 430.

[0085] In this embodiment, the elastic member 250 is a spring, the contact member 240 is an elliptical cam, and the outer circumference 241 is alternately provided with two groups of long sides 242 and short sides 243; when the contact member 240 is rotating, the outer circumference 241 is continuously tangent to the surfaces of the passive wheel structural assembly 300 and the active wheel structural assembly 400. With such a structural design, only one first motor 210 is used to control the relative distance 260 between the passive wheel structural assembly 300 and the active wheel structural assembly 400, thereby fundamentally eliminating the possibility of the test tube 900 to be scanned touching the passive wheel structural assembly 300 in an uncontrolled manner.

[0086] The following example illustrates the application of the rotating clamping structure 100 . In one embodiment, the rotating clamping structure 100 includes a clamping structure assembly 200 , a passive wheel structure assembly 300 , and a driving wheel structure assembly 400 .

[0087] The clamping structure assembly 200 includes a first motor 210, a fixing plate 220, a guide rail 230 and an abutment 240. The fixing plate 220 is fixed to the frame, the guide rail 230 is fixed to the fixing plate 220, the guide rail 230 is a guide rail of a double slider, the first motor 210 is fixed to the fixing plate 220, the abutment 240 is fixed to the motor shaft of the first motor 210, and the abutment 240 can rotate with the rotation of the motor shaft; the abutment 240 is an elliptical cam or an ellipsoid.

[0088] The passive wheel structural assembly 300 includes a passive support 310, a bearing 320 and a passive wheel 330. The passive support 310 is mounted on the first slider 231 of the guide rail 230. The mounting shaft 340 is fixed on the passive support 310, and the bearing 320 is mounted on the mounting shaft 340. The outer ring surface of the bearing 320 is tangent to the outer surface of the abutment member 240, such as an elliptical cam. The two passive wheels 330 are mounted on the passive support 310 in order to cooperate with the active wheel 430 to form a three-point tangent effect on the test tube 900.

[0089] The driving wheel structural assembly 400 includes a driving bracket 410, a second motor 420, a driving wheel 430 and a driving shaft 440. The driving bracket 410 is mounted on the second slider 232 of the guide rail 230. The driving shaft 440 is mounted on the driving bracket 410, and the driving wheel 430 is mounted on the driving shaft 440.

[0090] Both the passive wheel structural assembly 300 and the active wheel structural assembly 400 can slide on the guide rail 230 of the double slider, and the passive wheel structural assembly 300 and the active wheel structural assembly 400 are pulled by the elastic member 250, forcing the passive wheel 330 and the active wheel 430 substructures to be close to and tangent to the middle abutment 240. At this time, when the abutment 240 rotates to the long side 242, the two substructures are spread apart, that is, the passive wheel 330 and the active wheel 430 are spread apart, that is, the passive wheel structural assembly 300 and the active wheel structural assembly 400 are spread apart, and when the abutment 240 rotates to the short side 243, the two substructures are tightened while always being tangent to the abutment 240 under the action of the elastic member 250.

[0091] In one embodiment, a test tube identification code rotating scanning device 700 is shown in Figures 5 and 7, which includes a scanner 800 and the rotating clamping structure 100 described in any embodiment, and the scanner 800 is adjacent to the rotating scanning position 500 of the rotating clamping structure 100; in this embodiment, the test tube identification code rotating scanning device 700 clamps the test tube 900 to be scanned for scanning as shown in Figures 6 and 8.

[0092] Exemplarily, the test tube identification code rotating scanning device 700 includes a scanner 800 and a rotating clamping structure 100, and the rotating clamping structure 100 includes a clamping structure assembly 200, a passive wheel structure assembly 300 and a driving wheel structure assembly 400: the passive wheel structure assembly 300 and the driving wheel structure assembly 400 are both arranged on the clamping structure assembly 200, and the clamping structure assembly 200 is provided with a first motor 210 for adjusting the relative distance 260 between the passive wheel structure assembly 300 and the driving wheel structure assembly 400, so that the passive wheel structure assembly 300 and the driving wheel structure assembly 400 can jointly clamp the test tube 900 to be scanned; the driving wheel structure assembly 400 is provided with a second motor 420 for driving the test tube 900 to be scanned to rotate when the passive wheel structure assembly 300 and the driving wheel structure assembly 400 jointly clamp the test tube 900 to be scanned. The rest of the embodiments are similar and will not be described in detail. Such a structural design also has the advantages of the rotating clamping structure 100. Only two motors are used. One motor controls the relative distance 260 between the passive wheel structure assembly 300 and the active wheel structure assembly 400, and the other motor controls the rotation of the active wheel. This fundamentally eliminates the possibility of the test tube 900 to be scanned touching the passive wheel structure assembly 300 in an uncontrolled manner. It can realize clamping and releasing actions in a smaller volume design, and has the advantages of simple structure and easy application. The scope of application includes but is not limited to barcode scanning of sample tubes.

[0093] Exemplarily, the identification code of the test tube 900 to be scanned is a barcode, that is, a row-type two-dimensional code, and the scanner 800 is a barcode scanner; or, in one embodiment, the identification code of the test tube 900 to be scanned is a matrix-type two-dimensional code, and the scanner 800 is a matrix-type two-dimensional code scanner.

[0094] Exemplarily, the basic working process of the test tube identification code rotating scanning device 700 is described as follows.

[0095] The abutment member 240 rotates to the long side portion 242 , and when the code-scanning test tube 900 reaches the rotating code-scanning position 500 , the abutment member 240 rotates to the short side portion 243 , so that the active wheel 430 and the passive wheel 330 clamp the test tube 900 .

[0096] The driving wheel 430 rotates, and the friction force drives the test tube 900 to also start rotating.

[0097] The scanner 800 works and scans the barcode on the rotating test tube 900 to be scanned.

[0098] After the code scanning is completed, the abutment member 240 rotates to the long side portion 242, the driving wheel 430 and the driven wheel 330 separate, and the code scanning is completed.

[0099] If necessary, the test tube 900 to be scanned can be driven to the rotating scanning position 500 to execute a scanning cycle.
