DETAILED DESCRIPTION

[0041] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0042] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0044] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] See also Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of the first embodiment of the rotary scanning mechanism of the present application, Figure 2 The rotating scanning mechanism A provided in the embodiment of the present application comprises a frame 1, a guide rail 2, at least one scanning component 3 and a control unit (not shown).

[0046] The guide rail 2 is disposed on the frame 1 along a first direction X, and at least one scanning component 3 is disposed on the guide rail 2 and moves along the extension direction of the guide rail 2. Figure 1 As shown, the scanning assembly 3 can move along the first direction X on the guide rail 2 .

[0047] like Figure 2As shown, in this embodiment, the scanning component 3 includes a rotating component 31, a locking component 32 and a scanning component 33. The locking component 32 and the rotating component 31 cooperate to lock the test tube, the rotating component 31 is used to drive the test tube to rotate, and the scanning component 33 is used to scan the rotating test tube. Therefore, when the scanning component 3 encounters a situation where the barcode on the test tube is not facing the scanning component 33, or the barcode on the test tube is not pasted in a standard manner, the scanning component 33 can completely scan the barcode on the test tube and obtain the scanning information of the test tube.

[0048] The control unit is connected to the scanning component 3 and is used to control the operation of the scanning component 3 .

[0049] When the scanning component 3 performs a rotational scanning process on the test tube, the control unit is used to control the scanning component 3 to move to the target position on the guide rail 2, and control the scanning component 3 to lock and drive the test tube to rotate, scan the rotating test tube, and obtain the scanning information of the test tube.

[0050] Different from the existing solution of rotating the test tube to a certain angle and then stopping the rotation, and then scanning the test tube with a scanner, the solution provided by the present application of scanning while rotating significantly improves the scanning efficiency. At the same time, if the test tube is rotated to a certain angle and then stopped, and then scanned, it cannot be guaranteed that when the test tube stops, the barcode on the test tube is facing the scanner and can be scanned by the scanner; in extreme cases, the test tube may be rotated multiple times and the barcode at the test tube stop position is not facing the scanner, so the problem of failure to scan the barcode on the test tube cannot be solved smoothly.

[0051] In the present application, the scanning component 3 scans the rotating test tube, which can ensure that during the scanning process of the scanning unit 33 scanning the test tube, the barcode is always facing the scanning unit 33 for a period of time, so that the scanning unit 33 can successfully scan the barcode on the test tube. Furthermore, the rotation speed of the test tube cannot be too fast, otherwise the scanning unit 33 cannot successfully scan the barcode, and the rotation speed of the test tube cannot be too slow, otherwise it will affect the scanning efficiency of the scanning unit 33 for the barcode. In this embodiment, the rotation speed of the test tube is 1r / s~2r / s, which improves the scanning efficiency of the scanning unit 33 while ensuring that the scanning unit 33 can successfully scan the barcode. It can be understood that in other embodiments, on the premise of ensuring that the scanning unit 33 can successfully scan the barcode, the user can set the rotation speed of the test tube according to needs.

[0052] Among them, the target position on the guide rail 2 is the position on the guide rail 2 where the scanning component 3 can operate the test tube, so it can be understood that the target position on the guide rail 2 is not a specific position in the physical sense. When the scanning component 3 is to perform a rotational scanning process on the first test tube, the target position on the guide rail 2 corresponds to the position of the first test tube; when the scanning component 3 is to perform a rotational scanning process on the second test tube, the target position on the guide rail 2 corresponds to the position of the second test tube. The control unit can obtain the test tube position where the scanning component 3 is to perform a rotational scanning process, and then plan the target position on the guide rail 2, and control the scanning component 3 to move to the target position.

[0053] After the control unit controls the scanning component 3 to move to the target position on the guide rail 2, the control unit controls the scanning component 3 to lock and rotate the test tube to scan the rotating test tube. Specifically, the control unit may control the locking component 32 to move and cooperate with the rotating component 31 to lock the test tube, and control the rotating component 31 to drive the test tube to rotate, and control the scanning component 33 to scan the rotating test tube to obtain the scanning information of the test tube. After the scanning component 33 obtains the scanning information of the test tube, the scanning information can be uploaded to the control unit, and the control unit receives and stores the scanning information of the test tube.

[0054] In summary, the rotating scanning mechanism A includes a frame 1, a guide rail 2, a scanning component 3 and a control unit. The scanning component 3 can move on the guide rail 2. When the scanning component 3 is to perform a rotational scanning process on the test tube, the control unit controls the scanning component 3 to move to the target position on the guide rail 2, and controls the scanning component 3 to lock and drive the test tube to rotate, and scans the rotating test tube, so that the scanning component 33 can scan the barcode on the complete test tube, thereby improving the efficiency of the scanning component 33 in scanning the barcode on the test tube, improving the efficiency and accuracy of the scanning component 3 in scanning the test tube and obtaining the test tube scanning information, and improving the user experience of the rotating scanning mechanism A.

[0055] Alternatively, if Figure 1 As shown, the scanning assembly 3 includes a first scanning assembly 301 and a second scanning assembly 302. In this embodiment, the first scanning assembly 301 and the second scanning assembly 302 may be scanning assemblies with the same structure and symmetrically arranged relative to the vertical center axis of the guide rail 2.

[0056] The first scanning component 301 is disposed at the first end of the guide rail 2, and is used to perform a rotational scanning process on the test tube near the first end of the guide rail 2; the second scanning component 302 is disposed at the second end of the guide rail 2, and is used to perform a rotational scanning process on the test tube near the second end of the guide rail 2. The first scanning component 301 at the first end of the guide rail 2 and the second scanning component 302 at the second end of the guide rail 2 can simultaneously perform a rotational scanning process on two test tubes, obtain scanning information of the two test tubes, and improve the efficiency of the rotational scanning mechanism A in performing rotational scanning on the test tubes.

[0057] The control unit is connected to the first scanning component 301 and the second scanning component 302, and is used to control the first scanning component 301 and the second scanning component 302 to move toward and / or away from each other, and / or in the same direction on the guide rail 2, so that the first scanning component 301 and the second scanning component 302 can simultaneously perform a rotational scanning process of the test tube.

[0058] Among them, Figure 3 As shown, Figure 3 It is a structural schematic diagram of the first embodiment of the guide rail of the present application. The first end of the guide rail 2 is end B, the second end is end C, and line D is the center line of the guide rail 2. For the convenience of description, the guide rail section between end B and line D is referred to as the first guide rail area, and the guide rail section between line D and end C is referred to as the second guide rail area.

[0059] In one embodiment, the first scanning component 301 can be set at the B end, and the control unit controls the first scanning component 301 to move in the first guide rail area; the second scanning component 302 can be set at the C end, and the control unit controls the second scanning component 302 to move in the second guide rail area. Before the first scanning component 301 and the second scanning component 302 are to perform a scanning process on the test tube, they are respectively set at the B end and the C end of the guide rail; during the process of the first scanning component 301 and the second scanning component 302 scanning the test tube, the control unit can control the first scanning component 301 to move along the direction of the B end pointing to the D line on the guide rail 2, and perform a rotation scanning process on the test tube; at the same time, the control unit controls the second scanning component 302 to move along the direction of the C end pointing to the D line on the guide rail 2, and perform a rotation scanning process on the test tube. That is, the control unit controls the first scanning component 301 and the second scanning component 302 to move toward each other on the guide rail 2, so that the first scanning component 301 and the second scanning component 302 simultaneously perform the rotation scanning process of the test tube, thereby improving the efficiency of the rotation scanning mechanism A in scanning the test tube.

[0060] In one embodiment, the first scanning component 301 can be set at the B end, and the control unit controls the first scanning component 301 to move in the first guide rail area; the second scanning component 302 can be set at one end of the D line close to the second guide rail area, and the control unit controls the second scanning component 302 to move in the second guide rail area. Before the first scanning component 301 and the second scanning component 302 are to perform a scanning process on the test tube, they are respectively set at the B end of the guide rail and the end of the D line close to the second guide rail area; during the scanning process of the test tube by the first scanning component 301 and the second scanning component 302, the control unit can control the first scanning component 301 to move along the direction from the B end to the D line on the guide rail 2, and perform a rotation scanning process on the test tube; at the same time, the control unit controls the second scanning component 302 to move along the direction from the D line to the C end on the guide rail 2, and perform a rotation scanning process on the test tube. That is, the control unit controls the first scanning component 301 and the second scanning component 302 to move in the same direction on the guide rail 2, so that the first scanning component 301 and the second scanning component 302 simultaneously perform the rotation scanning process of the test tube.

[0061] In another embodiment, the first scanning component 301 can be set at one end of the D line close to the first guide rail area, and the control unit controls the first scanning component 301 to move in the first guide rail area; the second scanning component 302 can be set at one end of the D line close to the second guide rail area, and the control unit controls the second scanning component 302 to move in the second guide rail area. Before the first scanning component 301 and the second scanning component 302 are to perform a scanning process on the test tube, they are respectively set at one end of the D line close to the first guide rail area and one end of the D line close to the second guide rail area of ​​the guide rail; during the scanning process of the test tube by the first scanning component 301 and the second scanning component 302, the control unit can control the first scanning component 301 to move on the guide rail 2 in the direction of the D line pointing to the B end, and perform a rotation scanning process on the test tube; at the same time, the control unit controls the second scanning component 302 to move on the guide rail 2 in the direction of the D line pointing to the C end, and perform a rotation scanning process on the test tube. That is, the control unit controls the first scanning assembly 301 and the second scanning assembly 302 to move oppositely on the guide rail 2, so that the first scanning assembly 301 and the second scanning assembly 302 perform the rotation scanning process of the test tube at the same time.

[0062] In summary, the control unit can control the movement of the first scanning component 301 on the first guide rail area and the movement of the second scanning component 302 on the second guide rail area, so that the first scanning component 301 and the second scanning component 302 simultaneously perform a rotation scanning process on the test tube, thereby improving the efficiency of the test tube scanning by the rotation scanning mechanism A. In addition, the control unit controls the first scanning component 301 to move only on the first guide rail area and the second scanning component 302 to move only on the second guide rail area, so that the first scanning component 301 and the second scanning component 302 will not collide with each other when moving on the guide rail 2, thereby ensuring the safety and stability of the first scanning component 301 and the second scanning component 302.

[0063] Optionally, see Figure 2 The rotating assembly 31 includes a rotating motor 311 , a synchronous wheel 312 and a synchronous belt 313 .

[0064] The synchronous wheel 312 cooperates with the locking assembly 32 to lock the test tube, and the synchronous wheel 312 can rotate to drive the test tube to rotate. The synchronous belt 313 connects the rotating motor 311 and the synchronous wheel 312. The rotating motor 311 starts to drive the synchronous belt 313 to rotate, thereby driving the synchronous wheel 312 to rotate.

[0065] In one embodiment, the locking assembly 32 may include a locking motor 321 and a locking handle 322. The locking motor 321 is started to drive the locking handle 322 to move in a direction close to the synchronous wheel 312 or in a direction away from the synchronous wheel 312.

[0066] The locking assembly 32 cooperates with the synchronous wheel 312 to lock the test tube, which is actually the locking handle 322 and the synchronous wheel 312 cooperate to lock the test tube. Specifically, when the control unit controls the scanning assembly 3 to move to the target position on the guide rail 2, the synchronous wheel 312 moves to one side of the test tube, and the locking motor 321 controls the locking handle 322 to move in the direction close to the synchronous wheel 312 (the direction close to the test tube) until the locking handle 322 pushes the test tube to contact the synchronous wheel 312. At this time, one side of the test tube is fixed by the synchronous wheel 312, and the other side is fixed by the locking handle 322. The synchronous wheel 312 and the locking handle 322 cooperate to lock the test tube.

[0067] The test tube is arranged on the test tube rack. In order to prevent the locking pusher 322 from pushing the test tube to contact the synchronous wheel 312 and causing the test tube to cause the test tube to tip over, when the synchronous wheel 312 moves to one side of the test tube, the spacing between the synchronous wheel 312 and the test tube should not be too large, and a gap of about 1 mm is provided to ensure that when the locking pusher 322 pushes the test tube to contact the synchronous wheel 312, the moving distance of the test tube will not be too large, causing the test tube or the test tube rack to tilt, thereby improving the safety of the scanning assembly 3 locking the test tube. In addition, the synchronous wheel 312 maintains a spacing distance from the test tube, allowing the test tube to shake in a small range on the test tube rack, thereby improving the applicability of the scanning assembly 3 to test tubes in different postures and improving the practicality of the rotating scanning mechanism A.

[0068] In one embodiment, a spring assembly (not shown) may be provided between the locking handle 322 and the locking motor 321. The control unit controls the locking motor 321 to move according to a fixed number of steps each time. That is, the locking motor 321 controls the locking handle 322 to move the same distance in the direction of approaching the test tube each time. Before the locking handle 322 contacts the test tube, the movements of the locking handle 322 and the locking motor 321 are synchronized. After the locking handle 322 contacts the test tube, the locking handle 322 provides a force to the test tube to approach the synchronous wheel 312, and the test tube will provide resistance to the locking handle 322 in the opposite direction. When the test tube provides resistance to the locking handle 322, the spring assembly between the locking handle 322 and the locking motor 321 takes effect, so that the locking handle 322 provides an appropriate force to the test tube, and the test tube will not be damaged while locking the test tube, and the locking handle 322 can cooperate with the synchronous wheel 312 to lock the test tube.

[0069] The locking motor 321 moves with a fixed number of steps to move the locking handle 322 a fixed distance. After the locking handle 322 moves, the locking motor 321 may not stop moving even after the locking handle 322 pushes the test tube to contact the synchronous wheel 312.

[0070] At this time, the locking handle 322 cannot continue to push the test tube toward the synchronous wheel 312, and the force of the locking motor 321 driving the locking handle 322 to move will compress the spring assembly. Due to the compression of the spring assembly between the locking motor 321 and the locking handle 322, the locking handle 322 is not driven by the locking motor 321 to continue moving forward. At this time, the spring assembly provides a force for the locking handle 322 to approach the test tube, and the locking handle 322 and the synchronous wheel 312 lock the test tube. This avoids the locking handle 322 being driven by the locking motor 321 to move too far toward the test tube, squeezing the test tube, and damaging the test tube.

[0071] In summary, the locking motor 321 drives the locking handle 322 to move a fixed distance with a fixed number of steps, which simplifies the control of the locking motor 321 by the control unit. A spring assembly is provided between the locking motor 321 and the locking handle 322. After the locking handle 322 contacts the test tube, the spring assembly converts the driving force of the locking motor 321 on the locking handle 322 into the compression deformation of the spring assembly, so as to prevent the locking handle 322 from squeezing the test tube. At the same time, the compressed spring assembly provides the locking handle 322 with a force to approach the test tube, so that the locking handle 322 and the synchronous wheel 312 further lock the test tube.

[0072] Please continue reading Figure 2 After the locking assembly 32 and the synchronous wheel 312 lock the test tube, the control unit controls the synchronous wheel 312 to drive the test tube to rotate.

[0073] Specifically, the control unit controls the rotating motor 311 to start, so that the synchronous belt 313 connected to the rotating motor 311 is driven as the rotating motor 311 is started, and drives the synchronous wheel 312 connected to the synchronous belt 313 to rotate.

[0074] In this embodiment, the synchronous wheel 312 can be made of rubber with high friction to ensure that the synchronous wheel 312 drives the test tube to rotate. In other embodiments, the synchronous wheel 312 can also be made of other materials with high friction. On the basis of ensuring that the synchronous wheel 312 drives the test tube to rotate, the present application does not limit the manufacturing material of the synchronous wheel 312.

[0075] The control unit is also used to control the rotating motor 311 to drive the synchronous belt 313 to rotate clockwise and / or counterclockwise, and then control the synchronous wheel 312 to drive the test tube to rotate counterclockwise and / or clockwise.

[0076] Optionally, the rotary scanning mechanism A also includes a test tube rack sampling assembly (not shown).

[0077] The test tube rack sampling assembly is arranged in parallel and at intervals with the guide rail, and is used to move the test tube rack loaded with test tubes to the corresponding position of the guide rail 2.

[0078] See also Figure 3 , the test tube rack sampling assembly moves the test tube rack to the corresponding position of the guide rail 2, that is, the test tube rack sampling assembly moves the test tube to the corresponding position of the area where the scanning assembly 3 can move on the guide rail 2, and then the scanning assembly 3 moves on the guide rail 2 and performs a rotation scanning process on the test tube on the test tube rack.

[0079] In this embodiment, after the test tube rack sampling assembly moves the test tube rack to the corresponding position of the guide rail 2, the control unit is further used to:

[0080] The first scanning component 301 is controlled to perform a rotational scanning process on the test tube at the first end of the test tube rack, and the second scanning component 302 is controlled to perform a rotational scanning process on the test tube at the second end of the test tube rack to obtain scanning information of the test tube on the test tube rack. The first end of the test tube rack is arranged corresponding to the first end of the guide rail 2, and the second end of the test tube rack is arranged corresponding to the second end of the guide rail 2.

[0081] Specifically, Figure 3 As shown, the first end of the test tube rack is arranged corresponding to the B end on the guide rail 2, and the second end of the test tube rack is arranged corresponding to the C end on the guide rail 2. The control unit controls the first scanning component 301 to move on the first guide rail area to perform a rotational scanning process on the test tubes at the first end of the test tube rack, that is, to perform a rotational scanning on the five test tubes located at the corresponding positions of the first guide rail area. The control unit simultaneously controls the second scanning component 302 to move on the second guide rail area to perform a rotational scanning process on the test tubes at the second end of the test tube rack, that is, to perform a rotational scanning on the five test tubes located at the corresponding positions of the second guide rail area. By controlling the first scanning component 301 and the second scanning component 302 to simultaneously perform a rotational scanning process on the test tubes, the efficiency of the scanning component 3 in performing a rotational scanning on the test tubes is improved, and the scanning efficiency of the rotational scanning mechanism A is improved.

[0082] In summary, the rotary scanning mechanism A includes a first scanning component 301 and a second scanning component 302. The control unit controls the first scanning component 301 and the second scanning component 302 to move on the guide rail 2 at the same time, performs a rotary scanning process on the test tube, and improves the rotary scanning efficiency of the test tube by the scanning component 3. At the same time, the control unit controls the first scanning component 301 and the second scanning component 302 to move only in the guide rail area they are responsible for, so as to avoid collision between the first scanning component 301 and the second scanning component 302 when moving, and improve the safety of the scanning component 3 when moving.

[0083] The synchronous wheel 312 in the rotating component 31 and the locking push handle 322 in the locking component 32 cooperate to lock the test tube. The rotation of the synchronous wheel 312 drives the test tube to rotate clockwise and / or counterclockwise. The scanning component 33 scans the rotating test tube, thereby increasing the possibility of the scanning component 33 obtaining the complete barcode on the test tube, thereby improving the efficiency of the scanning component 3 in scanning the test tube.

[0084] In order to improve the efficiency of the scanning component 3 in scanning the test tube and obtaining the test tube scanning information, the present application also proposes a test tube rotation scanning method, which is applied to the rotation scanning mechanism A. Figure 4 , Figure 4 1 is a flow chart of the first embodiment of the test tube rotation scanning method of the present application. The method proposed in the embodiment of the present application comprises the following steps:

[0085] S1: Control the test tube rack to move to the corresponding position of the guide rail 2, and control the scanning component 3 to move to the target position on the guide rail 2, and lock and rotate the test tube.

[0086] After the control unit receives the instruction to obtain the scanning information of the test tube on the test tube rack, the control unit controls the test tube rack sample introduction mechanism to move the test tube rack to the corresponding position of the guide rail 2. Then the control unit controls the scanning component 3 to move to the target position on the guide rail 2, locks and rotates the test tube.

[0087] In one embodiment, when the rotating scanning mechanism A includes a first scanning component 301 and a second scanning component 302, the step of the control unit controlling the scanning component 3 to move to a target position on the guide rail 2 includes:

[0088] The control unit controls the first scanning assembly 301 to move to the first target position along the guide rail 2, locks and rotates the first test tube, and controls the second scanning assembly 302 to move to the second target position along the guide rail 2, locks and rotates the second test tube.

[0089] The first target position is set at the first end of the guide rail 2, the second target position is set at the second end of the guide rail 2, the first test tube is set at the first end of the test tube rack, and the second test tube is set at the second end of the test tube rack. Figure 3 The first target position is set in the first guide rail area on the guide rail 2, the second target position is set in the second guide rail area on the guide rail 2, the first test tube is one of the five test tubes corresponding to the first guide rail area, and the second test tube is one of the five test tubes corresponding to the second guide rail area.

[0090] S2: Control the scanning component 33 to scan the rotating test tube, obtain the scanning information of the test tube, and end the rotation scanning process of the test tube.

[0091] In step S1, the control unit has controlled the scanning component 3 to lock and rotate the test tube, and then the control unit controls the scanning part 33 in the scanning component 3 to scan the rotating test tube. The scanning part 33 obtains the scanning information of the test tube and uploads the scanning information to the control unit. The control unit receives the scanning information uploaded by the scanning part 33.

[0092] Among them, when the rotating scanning mechanism A includes a first scanning component 301 and a second scanning component 302, the control unit simultaneously controls the first scanning component 301 and the second scanning component 302 to lock the test tube and drive the test tube to rotate. It can be obtained from the foregoing that the first scanning component 301 and the second scanning component 302 can be scanning components with the same structure, that is, the control unit can control the scanning component in the first scanning component 301 to scan the first test tube in rotation and obtain the scanning information of the first test tube, and at the same time control the scanning component in the second scanning component 302 to scan the second test tube in rotation and obtain the scanning information of the second test tube. The control unit can obtain the scanning information of the two test tubes at the same time, thereby improving the efficiency of the rotating scanning mechanism A in scanning the test tubes.

[0093] After the scanning component 3 scans the test tube and obtains the scanning information of the test tube, the control unit controls the scanning component 3 to release the test tube, thereby ending the rotation scanning process of the test tube.

[0094] In actual operation, due to reasons such as the barcode on the test tube is not pasted in a standard manner, the scanning component 3 performs a rotation scanning process on the test tube, and there may be a situation where the scanning component 33 fails to scan the barcode on the test tube. Therefore, please refer to Figure 5 , Figure 5 2 is a flow chart of the second embodiment of the test tube rotation scanning method of the present application. The specific steps of the scanning component 3 performing rotation scanning on the test tube include:

[0095] S51: Control the rotating component 31 to drive the test tube to rotate clockwise, and control the scanning component 33 to scan the test tube.

[0096] After the scanning component 3 locks the test tube, the control unit first controls the rotating component 31 to drive the test tube to rotate clockwise, and controls the scanning component 33 to scan the rotating test tube. In another embodiment, the control unit can also control the rotating component 31 to first drive the test tube to rotate counterclockwise, and the present application does not limit whether the test tube rotates clockwise or counterclockwise first.

[0097] S52: Determine whether the scanning document 33 has scanned the scanning information of the test tube.

[0098] If the scanning piece 33 scans the scanning information of the test tube, the scanning piece 33 will upload the scanning information to the control unit, and the control unit receives and stores the scanning information. Therefore, a response time can be preset. Within the response time, if the control unit receives the scanning information uploaded by the scanning piece 33, it is determined that the scanning piece 33 scanned the scanning information of the test tube, and the process proceeds to step S53. If the control unit does not receive the scanning information uploaded by the scanning piece 33 within the response time, it is determined that the scanning piece 33 failed to successfully scan the scanning information of the test tube, and the process proceeds to step S54.

[0099] S53: End the rotation scanning process of the test tube.

[0100] After the control unit receives the scanning information of the test tube and determines that the scanning member 33 has successfully scanned the scanning information of the test tube, the control unit ends the rotation scanning process of the test tube and controls the scanning component 3 to release the test tube.

[0101] S54: Control the rotating component 31 to drive the test tube to rotate counterclockwise or clockwise, and control the scanning component 33 to scan the test tube.

[0102] The control unit does not receive the scanning information of the test tube within the response time, and determines that the scanner 33 fails to successfully scan the barcode of the test tube. The control unit then controls the rotating assembly 31 to drive the test tube to rotate counterclockwise, and controls the scanner 33 to scan the test tube.

[0103] If, in step S51, the control unit controls the rotating assembly 31 to scan the test tube clockwise, then after determining that the scanning unit 33 fails to scan the scanning information of the test tube, the control unit controls the rotating assembly 31 to drive the test tube to rotate counterclockwise. If, in step S51, the control unit controls the rotating assembly 31 to scan the test tube counterclockwise, then after determining that the scanning unit 33 fails to scan the scanning information of the test tube, the control unit controls the rotating assembly 31 to drive the test tube to rotate clockwise.

[0104] Among them, the deviation of the angle of light irradiated by the scanner 33 to the barcode on the test tube, or the reflection of the light by the barcode, are the reasons for the success or failure of the scanner 33 to scan the test tube. Therefore, in this application, after the scanner 33 scans the rotating test tube, if the control unit determines that the scanner 33 cannot scan the scanning information of the test tube, that is, at this time, there is a deviation in the angle of light irradiated by the scanner 33 to the barcode on the test tube, or the reflection of the light by the barcode does not meet the requirements of the scanner 33, etc., the control unit controls the rotating component 31 to drive the test tube to rotate in the opposite direction, and the scanner 33 scans the test tube rotating in the opposite direction again, thereby increasing the probability of the scanner 33 scanning the test tube successfully, improving the efficiency of the scanning component 3 scanning the test tube, and improving the user experience of the rotating scanning mechanism A.

[0105] In one embodiment, the rotation speed of the test tube is 1r / s to 2r / s, and the test tube can rotate clockwise for 2s (it can be understood that this is an example and does not limit the rotation time of the test tube. The rotation time of the test tube can be other time lengths), that is, the response time can be 2s (because the scanning piece 33 uploads information very quickly, the time difference for the scanning piece 33 to upload the scan information to the control unit is ignored here). When the rotation speed of the test tube is 2r / s, that is, after the test tube rotates clockwise for 4 turns, the scanning piece 33 still fails to scan the scan information successfully, and it is determined that the scanning piece 33 fails to obtain the scan information of the test tube.

[0106] At this time, the rotating component 31 may not drive the test tube to rotate counterclockwise, but reduce the rotation speed of the test tube, for example, from 2r / s to 1r / s, to drive the test tube to rotate clockwise at a lower rotation speed. The scanning component 33 re-scans the test tube rotating clockwise to avoid scanning failure due to the excessive rotation speed of the test tube.

[0107] Alternatively, after the scanning component 33 fails to scan the test tube rotating clockwise, the rotating assembly 31 drives the test tube to rotate counterclockwise at a lower rotation speed.

[0108] In summary, after the scanning part 33 fails to scan the rotating test tube, the rotating component 31 can drive the test tube to rotate in the same direction or opposite direction at a lower rotation speed, and the scanning part 33 scans the test tube rotating at a lower speed to avoid scanning failure caused by the test tube rotating too fast, thereby improving the scanning efficiency of the scanning part 33.

[0109] In another case, if the scanner 33 successfully obtains the scanning information of the test tube in the first rotation of the test tube, in order to ensure the accuracy of the scanning information obtained by the scanner 33, the scanner 33 can continue to scan the test tube during the rotation of the test tube, instead of stopping scanning immediately after obtaining the scanning information.

[0110] In one embodiment, the rotation speed of the test tube is 2r / s, and the rotation time of the test tube can be 2s. In the extreme case, the test tube needs to rotate four times, that is, the scanner 33 can obtain scanning information of four test tubes. The four scanning information may be completely consistent (correct scanning information of the same test tube), or there may be inconsistent scanning information (wrong scanning information due to scanning errors of the scanner 33). At this time, the scanner 33 can compare and verify the four scanning information and take the scanning information with high repeatability as the correct scanning information.

[0111] Furthermore, the scanning piece 33 may acquire the scanning information of the test tube for the first time and then for the second time. If the scanning information acquired for the first time is consistent with the scanning information acquired for the second time, the scanning piece 33 directly determines that the acquired scanning information is correct scanning information, and there is no need to scan the entire rotation of the test tube, thereby improving the scanning efficiency of the scanning piece 33.

[0112] Optionally, in the above-mentioned multiple acquisitions of the scanning information of the test tube within the preset rotation time, the speed of each test tube rotation may be the same or different, and the direction of each test tube rotation may be the same or different. For example, when the scanning information of the test tube is acquired for the first time, the speed of the test tube rotation is 2r / s, and when the scanning information of the test tube is acquired for the second time, the speed of the test tube rotation may be 2r / s or 1r / s, 3r / s, 4r / s, etc.; when the scanning information of the test tube is acquired for the first time, the direction of the test tube rotation is clockwise, and when the scanning information of the test tube is acquired for the second time, the direction of the test tube rotation may be clockwise or counterclockwise.

[0113] In summary, after the scanning piece 33 scans the scanning information for the first time, in order to ensure the accuracy of the scanning information, the scanning piece 33 continues to scan within the rotation time of the test tube, and may obtain the second scanning information. If the first scanning information and the second scanning information are consistent, the scanning piece 33 determines that the scanning information is accurate; or the scanning piece 33 may obtain all the scanning information within the rotation time of the test tube, and judge the scanning information with high repeatability as accurate scanning information. The present application does not limit the specific steps of the scanning piece 33 obtaining accurate scanning information of the test tube within the rotation time of the test tube.

[0114] In one embodiment, when the rotating scanning mechanism A includes the first scanning component 301 and the second scanning component 302, if the scanning piece of the first scanning component 301 scans the scanning information of the first test tube, and the scanning piece of the second scanning component 302 fails to successfully scan the scanning information of the second test tube, as described in step S54, the control unit controls the second scanning component 302 to drive the second test tube to rotate in the opposite direction, and the scanning piece of the second scanning component 302 scans the second test tube rotating in the opposite direction. At this time, the control unit can also simultaneously control the first scanning component 301 to move to the test tube where the scanning information has not been obtained among the five test tubes corresponding to the first guide rail area, and perform a rotating scanning process on the test tube that has not obtained the scanning information.

[0115] It can be understood that the control unit proposed in the present application controls the first scanning component 301 to perform a rotational scanning process on the first test tube, and controls the second scanning component 302 to perform a rotational scanning process on the second test tube. The "simultaneous" does not mean that the first scanning component 301 and the second scanning component 302 move strictly synchronously. When the second scanning component 302 needs to rotationally scan the second test tube again, the first scanning component 301 that has successfully scanned the first test tube needs to stop running and wait for the second scanning component 302 to complete the rotational scanning of the second test tube.

[0116] Instead, the first scanning component 301 independently performs a rotational scanning process on the test tube it is responsible for, and the second scanning component 302 independently performs a scanning process on the test tube it is responsible for. For example, when the first scanning component 301 is in the process of rotationally scanning the test tube, the second scanning component 302 may be in the process of moving to the next test tube after successfully scanning the test tube, or the first scanning component 301 is in the process of moving to the next test tube after successfully scanning the test tube, while the second scanning component 302 is in the process of rotating and scanning the test tube in the opposite direction. The "simultaneously" described in this application does not limit the operation process of the first scanning component 301 and the second scanning component 302, but the first scanning component 301 and the second scanning component 302 are in operation at the same time in their respective responsible areas to scan the test tubes, so as to improve the scanning efficiency of the scanning component 3 on the test tubes.

[0117] In another embodiment, if the control unit controls the scanning component 3 to perform counterclockwise or clockwise rotation scanning on the test tube again, but still cannot successfully scan the scanning information of the test tube, that is, the barcode on the test tube may be severely deformed and cannot be adjusted by the rotating scanning mechanism A, and manual assistance is required, the control unit ends the rotation scanning process of the test tube, marks the test tube as a test tube that failed to scan, and controls the scanning component 3 to perform the rotation scanning process on the remaining test tubes on the test tube rack.

[0118] After the control unit controls the scanning component 3 to scan all the test tubes on the test tube rack, the control unit controls the scanning component 3 to scan the barcode on the test tube rack to obtain the scanning information of the test tube rack. Figure 6 , Figure 6 1 is a flow chart of the third embodiment of the test tube rotation scanning method of the present application. The scanning process of the scanning component 3 on the test tube rack includes the following steps:

[0119] S61: Control the scanning unit 33 to move to the first scanning position of the test tube rack, scan the test tube rack, and obtain scanning information of the test tube rack.

[0120] When the control unit determines that the scanning information of all the test tubes on the test tube rack has been received, or the scanning information of all the test tubes on the test tube rack except the test tubes marked as failed to be scanned has been received, the control unit determines that the scanning component 3 has performed a rotation scanning process on all the test tubes on the test tube rack. The control unit controls the scanning component 33 to move to the first scanning position of the test tube rack, scans the test tube rack, and obtains the scanning information of the test tube rack.

[0121] Specifically, the control unit controls the scanning component 3 to move to drive the scanning piece 33 to move to the first scanning position. The first scanning position is the position where the scanning piece 33 on the guide rail 2 is facing the barcode on the test tube rack. In one embodiment, the barcode on the test tube rack is pasted between the first test tube and the second test tube at one end of the test tube rack.

[0122] In the case where the rotating scanning mechanism A includes the first scanning component 301 and the second scanning component 302, if the barcode of the test tube rack is pasted between the first test tube and the second test tube at the first end of the test tube rack, that is, the first scanning position is located in the first guide rail area, then the first scanning component 301 is responsible for scanning the barcode of the test tube rack, and the control unit controls the first scanning component 301 to move to the first scanning position to scan the test tube rack. If the barcode of the test tube rack is pasted between the first test tube and the second test tube at the second end of the test tube rack, that is, the first scanning is located in the second guide rail area, then the second scanning component 302 is responsible for scanning the barcode of the test tube rack, and the control unit controls the second scanning component 302 to move to the first scanning position to scan the test tube rack. That is, according to the area where the barcode of the test tube rack is set, the control unit controls the scanning component 3 responsible for the area to scan the barcode of the test tube rack, thereby avoiding collision between multiple scanning components 3 when moving on the guide rail 2, improving the safety of the rotating scanning mechanism A, and shortening the moving distance of the scanning component 3 on the guide rail 2, thereby improving the scanning efficiency of the rotating scanning mechanism A on the test tube rack.

[0123] S62: It is determined that the scanning piece 33 has scanned the scanning information of the test tube rack, and the scanning process of the test tube rack is ended.

[0124] Among them, it is judged that the scanning piece 33 scans the scanning information of the test tube rack, which can be that the scanning piece 33 uploads the scanning information of the test tube rack to the control unit, and the control unit receives the scanning information of the test tube rack, then judges that the scanning piece 33 successfully scans the barcode of the test tube rack, and then ends the scanning process of the test tube rack, and controls the test tube rack sampling assembly to move the test tube rack out of the corresponding area of ​​the guide rail 2.

[0125] The barcode on the test tube rack may also have warped edges due to pasting, which may cause the scanner 33 to fail to scan the test tube rack successfully. In step S61, if the scanner 33 fails to successfully scan the scan information of the test tube rack at the first scanning position, the process proceeds to step S63-step S64.

[0126] S63: It is determined that the scanning unit 33 cannot scan the scanning information of the test tube rack, and the scanning unit 33 is controlled to move to the second scanning position.

[0127] In one embodiment, the user can also set in advance the response time of the control unit to receive the scanning information of the test tube rack. If the control unit does not receive the scanning information of the test tube rack uploaded by the scanning piece 33 within the response time, it is determined that the scanning piece 33 has failed to successfully scan the scanning information of the test tube rack. The control unit controls the scanning piece 33 (actually the scanning component 3) to move to the second scanning position. The second scanning position is at a preset distance from the first scanning position.

[0128] In one embodiment, the preset distance may be 5 mm, and there is a distance of 5 mm between the second scanning position and the first scanning position, that is, the second scanning position may be a position 5 mm away from the first scanning position along the first direction X, or may be a position 5 mm away from the first scanning position along the opposite direction of the first direction X. For the convenience of description, the second scanning position 5 mm away from the first scanning position along the first direction X is referred to as the right scanning position, and the second scanning position 5 mm away from the first scanning position along the opposite direction of the first direction X is referred to as the left scanning position. In other embodiments, the preset distance may also be other length values, and the present application does not limit the specific distance between the first scanning position and the second scanning position.

[0129] S64: Control the scanning unit 33 to scan the test tube rack at the second scanning position to obtain scanning information of the test tube rack.

[0130] The control unit may control the scanner 33 to move to the right scanning position first, and the scanner 33 scans the barcode of the test tube rack at the right scanning position. If the scanner 33 successfully scans the scanning information of the test tube rack at the right scanning position, the control unit ends the scanning process of the test tube rack.

[0131] If the scanning piece 33 fails to successfully scan the scanning information of the test tube rack at the right scanning position, the control unit controls the scanning piece 33 to move to the left scanning position to scan the test tube rack to obtain the scanning information of the test tube rack.

[0132] The scanning unit 33 completes one scan of the test tube rack at the left scanning position and the right scanning position respectively, and the control unit marks that the number of times the scanning unit 33 scans the test tube rack at the second scanning position is one.

[0133] In one embodiment, if the scanning piece 33 fails to scan the test tube rack at the second scanning position (the scanning piece 3 fails to successfully scan the scanning information of the test tube rack at the right scanning position and the left scanning position), and the control unit responds that the number of times the scanning piece 33 scans the test tube rack at the second scanning position does not exceed a preset number, the control unit controls the scanning piece 33 to scan the test tube rack again at the second scanning position to obtain the scanning information of the test tube rack.

[0134] Among them, as mentioned above, during the scanning process of the scanning piece 33, the scanning may fail due to the inconsistency between the light irradiation of the scanning piece 33 and the reflection of the barcode, the slight difference in the irradiation angle, etc. The preset number of times is set in this embodiment, and the fault tolerance number for scanning the test tube rack can be 3 times.

[0135] In response to the scanning part 33 scanning the test tube rack at the second scanning position for no more than 3 times, if the scanning part 33 is at the right scanning position at this time, the control unit can control the scanning part 33 to scan the test tube rack again at the right scanning position, and then move to the left scanning position to scan the test tube rack; or control the scanning part 33 to move to the left scanning position to scan, and then move to the right scanning position to scan. If the scanning part 33 successfully scans the scanning information of the test tube rack, the control unit ends the scanning process of the test tube rack.

[0136] If the scanning piece 33 fails to scan the test tube rack again, the control unit determines whether the scanning piece 33 scans the test tube rack again at the second scanning position for more than three times. If not, the control unit controls the scanning piece 33 to scan the test tube rack at the left scanning position and the right scanning position again. If it exceeds three times, the control unit ends the scanning process of the test tube rack and marks the test tube rack as having failed to scan.

[0137] In another embodiment, the preset number of times may also be other values, or there is no preset number of times. When the scanning piece 33 fails to scan at the left scanning position and the right scanning position for the first time, the control unit directly ends the scanning process of the test tube rack and marks the test tube rack scanning failure. The present application does not limit the number of fault tolerance times that the control unit allows the scanning piece 33 to scan the test tube rack at the second scanning position.

[0138] In summary, the method for rotationally scanning a test tube provided in the embodiment of the present application includes:

[0139] The rotating component 31 rotates to drive the test tube to rotate, and the scanning component 33 scans the rotating test tube. If the control unit determines that the scanning component 33 fails to successfully scan the scanning information of the test tube, it controls the rotating component 31 to drive the test tube to rotate in the opposite direction, and the scanning component 33 scans the test tube rotating in the opposite direction, thereby improving the success rate of the scanning component 33 in scanning the test tube and improving the scanning efficiency of the rotating scanning mechanism A on the test tube.

[0140] After the scanner 33 has finished scanning all the test tubes on the test tube rack, the scanner 33 moves to the first scanning position to scan the barcode of the test tube rack. If the control unit determines that the scanner 33 has not successfully scanned the scanning information of the test tube rack at the first scanning position, the scanner 33 is controlled to scan the barcode on the test tube rack at the second scanning position for a preset number of times, thereby improving the scanning success rate of the scanner 33 on the test tube rack and improving the scanning efficiency of the rotating scanning mechanism A on the test tube rack.

[0141] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
