[0051] Please refer to Figures 1 to 7 As shown, in order to achieve the above-mentioned purpose, the utility model proposes a detection device 100 for detecting the type of test tube 7. The detection device 100 includes a turntable assembly 2 and a test tube detection assembly 3. The turntable assembly 2 is provided with a rotating disk 21. The rotating disk 21 is formed with a plurality of placement positions, each placement position is used to place a test tube 7, and the test tube detection assembly 3 is arranged on the support seat 1. The test tube detection assembly 3 is provided with a detection space 324. The detection space 324 is arranged on one side of the rotating disk 21; wherein the rotating disk 21 is used to drive each test tube 7 to pass through the detection space 324 in turn to detect the type of the test tube 7.

[0052] In this embodiment, the detection device 100 is applied to sample detection instruments in the biomedical field, and is used to detect the type of test tube 7 containing samples, including but not limited to detecting and identifying the presence or absence of test tube 7, the length of test tube 7, the thickness of test tube 7, whether test tube 7 is provided with a tube cap, etc., so as to provide data support and information reference for subsequent detection and analysis, photographing, removing the cap and classification of test tube 7, etc.

[0053] In this embodiment, the turntable assembly 2 is also provided with a support base 1, which is a structural support component of the detection device 100. The support base 1 can be a support frame, a mounting table, a base, a base frame and other structures, which are not limited here. The support base 1 is used to install and support the rotating disk 21 and the test tube detection assembly 3, so that the test tube 7 can be placed through the rotating disk 21, and the test tube 7 can be detected and identified through the test tube detection assembly 3.

[0054] In this embodiment, the turntable assembly 2 is used to carry the test tube 7 on the one hand, and to transfer the carried test tube 7 on the other hand, and to make the test tube 7 pass through the test tube detection assembly 3 to perform test tube 7 type detection. The rotating disk 21 is rotatably disposed on the support seat 1. The rotating disk 21 can be rotated manually or driven by a servo motor. At the same time, a plurality of placement positions are arranged on the rotating disk 21 for placing the test tube 7.

[0055] It can be understood that the placement position can be provided with a placement groove, a placement hole or a fixing clamp and other structures to limit the placement of the test tube 7, and each placement position corresponds to a test tube 7. Multiple placement positions can be arranged in a ring shape along the rotation center of the rotating disk 21. When the rotating disk 21 rotates, it can drive the test tube 7 arranged on the rotating disk 21 to rotate together. By setting the rotating disk 21, the test tube 7 can be quickly transferred, which not only effectively reduces the space occupied by the related structures for transferring the test tube 7, but also improves the efficiency of transferring the test tube 7.

[0056] At the same time, the detection device 100 is further provided with a test tube detection component 3 corresponding to the rotating disk 21. The test tube detection component 3 is used to detect the type of the test tube 7, such as the length, thickness and whether the test tube 7 has a cap. The test tube detection component 3 forms a detection space 324. The detection space 324 is arranged on one side of the rotating disk, and the detection space 324 is partially located above the rotating disk 21, so that in the process of the rotating disk 21 driving the test tube 7 to rotate, each test tube 7 can be driven to pass through the detection space 324, so that the type of the test tube 7 can be detected one by one through the test tube detection component 3. The cooperation between the rotating disk 21 and the test tube detection component 3 can not only improve the efficiency of the test tube 7 transportation, and effectively improve the detection efficiency of the test tube 7 type, but also can perform continuous and rapid detection operations, and the test tube 7 located on the rotating disk 21 can directly pass through the detection space 324, so that the overall structure is compact and the space occupancy is reduced.

[0057] A detection device 100 of the present technical solution is used to detect the type of test tube 7. The detection device 100 is provided with a support base 1, and the support base 1 is used to install a turntable assembly 2 and a test tube detection assembly 3. The turntable assembly 2 is provided with a rotating disk 21, and the rotating disk 21 can be rotatably arranged on the support base 1. The rotating disk 21 forms a plurality of placement positions, each placement position is used to place a test tube 7, and the test tube detection assembly 3 is arranged on the support base 1. The test tube detection assembly 3 is provided with a detection space 324, wherein the rotating disk 21 rotates and drives each test tube 7 to pass through the detection space 324, so as to detect the type of test tube 7 through the test tube detection assembly 3. The rotating disk 21 can make the transportation of the test tube 7 more efficient. At the same time, the rotating disk 21 cooperates with the test tube detection assembly 3 to effectively improve the efficiency of detecting the type of test tube 7.

[0058] In one embodiment, each placement position forms a mounting hole 211 for placing the test tube 7. The distance between each mounting hole 211 and the rotation center of the rotating disk 21 is the same, and multiple mounting holes 211 are evenly spaced along the ring.

[0059] It is understandable that if Figure 1 , Figures 3 to 6As shown, the mounting holes 211 are used to place the test tubes 7, and the multiple mounting holes 211 are arranged in a ring shape around the rotation center of the rotating disk 21, so that the distances from each mounting hole 211 to the rotation center of the rotating disk 21 are the same. Therefore, in the process of the rotating disk 21 rotating to drive the test tubes 7 to move, the motion trajectories formed by the rotation of the multiple test tubes 7 are circular, which makes it easy to fix the position of the test tube detection assembly 3, so as to perform type detection on the multiple test tubes 7 one by one, thereby improving the convenience and efficiency of the detection.

[0060] At the same time, multiple mounting holes 211 are evenly spaced along the ring, so that the rotating disk 21 can only rotate a fixed angle each time, so as to simultaneously perform the loading, testing and unloading operations of the test tube 7. For example, four mounting holes 211 are provided, and the four mounting holes 211 are evenly arranged along the circumference. The rotating disk 21 can be set to rotate 90 degrees each time. Each time it rotates, one of the mounting holes 211 is used to add a test tube 7, and the next mounting hole 211 along the clockwise or counterclockwise direction is used to perform a test on the corresponding test tube detection component 3 to detect the type of test tube 7. After the detection, the next mounting hole 211 along the clockwise or counterclockwise direction is used for unloading the test tube 7, thereby completing the loading, testing and unloading of the entire test tube 7, so that the rotating disk 21 and the test tube detection component 3 cooperate efficiently, thereby improving the efficiency of test tube 7 detection.

[0061] In one embodiment, the hole wall of each mounting hole 211 is provided with a plurality of abutment protrusions 2111 , each abutment protrusion 2111 extends along the axial direction of the mounting hole 211 and protrudes away from the hole wall of the mounting hole 211 , and the plurality of abutment protrusions 2111 are evenly spaced around the axis of the mounting hole 211 .

[0062] It is understandable that if Figure 3 and Figure 6 As shown, a depression is formed between two adjacent abutment protrusions 2111, so that the multiple abutment protrusions 2111 form a plum blossom hole structure. When the test tube 7 is inserted into the mounting hole 211, the outer wall of the test tube 7 abuts against the abutment protrusions 2111, reducing the friction between the hole wall of the mounting hole 211 and the outer wall of the test tube 7, avoiding the test tube 7 and the mounting hole 211 from being too tightly connected due to the size difference of the test tube 7 diameter, and facilitating the separation of the test tube 7 and the mounting hole 211.

[0063] Furthermore, the abutment protrusion 2111 is an elastic structure, and the abutment protrusion 2111 can be made of an elastic material, such as a rubber material, or can be set to a spring structure, such as a metal spring connected to the hole wall of the mounting hole 211 at one end and freely movable at the other end. It can not only place test tubes 7 of various diameters by squeezing the elastic structure, but also tightly wrap the test tube 7, thereby improving the installation firmness of the test tube 7 and the rotating disk 21.

[0064] In one embodiment, the turntable assembly 2 also includes a turntable connecting rod 22 and two rotating disks 21. The turntable connecting rod 22 is used to connect the two rotating disks 21 so that the two rotating disks 21 are arranged in parallel and spaced apart along the direction of their rotation axes, and the mounting holes 211 provided on the two rotating disks 21 are respectively arranged correspondingly.

[0065] In this embodiment, if Figure 5 and Figure 6 As shown, the two rotating disks 21 are arranged in parallel and spaced apart along the direction of the rotating axis, and a plurality of mounting grooves 213 are arranged on opposite sides of the two rotating disks 21, and the mounting grooves 213 on the two rotating disks 21 are arranged correspondingly. The turntable assembly 2 includes a plurality of turntable connecting rods 22, and the two ends of each turntable connecting rod 22 are respectively arranged in the mounting grooves 213 on the two rotating disks 21, so that the two rotating disks 21 are arranged relatively spaced apart and maintained in connection. At the same time, the mounting holes 211 on the two rotating disks 21 are arranged correspondingly, and the mounting hole 211 located at the top is arranged to penetrate the rotating disk 21 in the vertical direction, so that the test tube 7 can pass through the mounting hole 211 located at the upper rotating disk 21 and extend into the mounting hole 211 located at the lower rotating disk 21.

[0066] It is understandable that when installing the test tube 7, it is difficult to ensure the convenient insertion and removal of the test tube 7 on the traditional single rotating disk 21, and it is difficult to ensure the installation stability of the test tube 7. However, by setting up two upper and lower rotating disks 21, the installation stability of the test tube 7 can be improved by the cooperation between the mounting hole 211 located on the upper rotating disk 21 and the mounting hole 211 located on the lower rotating disk 21, while also facilitating the insertion and removal of the test tube 7 and improving the convenience of loading and unloading.

[0067] Optionally, the rotating disk 21 is provided with a plurality of weight-reducing grooves 212, and the weight-reducing grooves 212 penetrate the rotating disk 21 along the rotation axis direction of the rotating disk 21; it can be understood that, if Figure 5 and Figure 6 As shown, the weight-reducing groove 212 is used to reduce the weight of the rotating disk 21 without changing the structural stability of the rotating disk 21, thereby reducing the weight of the entire device, reducing the output power of the driving member 23, and improving the output efficiency.

[0068] Optionally, the axis of the mounting hole 211 is parallel to the rotation axis of the rotating disk 21 to ensure that the test tube 7 is placed vertically along the rotation axis of the rotating disk 21, and the test tube detection assembly 3 can also be placed vertically corresponding to the test tube 7, thereby improving the compactness of the equipment and improving the detection accuracy of the test tube detection assembly 3.

[0069] In one embodiment, the test tube detection assembly 3 includes a mounting arm 31 and an infrared detection module 32. One end of the mounting arm 31 is connected to the support base 1, and the other end of the mounting arm 31 extends toward the rotating disk 21 and is spaced apart from the rotating disk 21 in the vertical direction. The infrared detection module 32 is disposed on the mounting arm 31. The infrared detection module 32 forms a detection space 324. The rotating disk 21 rotates and drives each test tube 7 to pass through the infrared detection module 32 to detect the type of the test tube 7.

[0070] In this embodiment, if Figures 1 to 5 as well as Figure 7 As shown, the mounting arm 31 is a structural support component of the test tube detection assembly 3, and the mounting arm 31 includes a first arm 311, a second arm 312, a connecting arm 313 and a mounting plate 314, wherein the first arm 311 is connected to the support base 1, the first arm 311 extends in the horizontal direction and is arranged beyond the edge of the rotating disk 21, the second arm 312 is connected to the end of the first arm 311 away from the support base 1, and extends in the vertical direction, so that the second arm 312 is spaced apart from the edge of the rotating disk 21, the connecting arm 313 is connected to the end of the second arm 312 away from the first arm 311, the connecting arm 313 and the first arm 311 extend in the same direction, the end of the connecting arm 313 away from the second arm 312 extends toward the direction of the rotating disk 21, and is connected to the mounting plate 314, so that the mounting plate 314 and part of the connecting arm 313 are located above the rotating disk 21 in the vertical direction and are spaced apart from the rotating disk 21.

[0071] It can be understood that the first arm 311, the second arm 312 and the connecting arm 313 together form an avoidance space 315, and part of the edge of the rotating disk 21 can extend into the avoidance space 315, and part of the connecting arm 313 and the mounting plate 314 are located above the rotating disk 21, thereby effectively saving space and improving the structural compactness of the detection device 100. Furthermore, the connecting arm 313 and the mounting plate 314 also form an installation space 316 connected to the avoidance space 315, and the installation space 316 is used to install the infrared detection module 32.

[0072] It can be understood that the infrared detection module 32 is arranged in the installation space 316, and the infrared detection module 32 forms a detection space 324. When the rotating disk 21 rotates, the multiple installation holes 211 on the rotating disk 21 will form a rotation trajectory. The rotation trajectory is a circle with the rotation center of the rotating disk 21 as the center and the center axis of the installation hole 211 to the rotation center of the rotating disk 21 as the radius. The rotation trajectory is directly below the detection space 324 in the vertical direction, that is, the detection space 324 is projected onto the surface of the rotating disk 21, and the projection will completely cover the rotation trajectory. Therefore, when the rotating disk 21 rotates, it will drive each test tube 7 to pass through the detection space 324, and the type of the test tube 7 will be detected by the infrared detection module 32, thereby realizing the efficient combination of the rotating disk 21 and the test tube 7 detection. On the basis of realizing the type detection of the test tube 7, the detection efficiency is improved by rotating the rotating disk 21.

[0073] In one embodiment, the infrared detection module 32 includes a first detection unit 321, a second detection unit 322 and a third detection unit 323, wherein the first detection unit 321 is used to detect the thickness of the test tube 7, the second detection unit 322 is used to detect the length of the test tube 7, and the third detection unit 323 is used to detect whether the test tube 7 has a cap; wherein the first detection unit 321, the second detection unit 322 and the third detection unit 323 are arranged at intervals along the vertical direction, the second detection unit 322 is located between the first detection unit 321 and the third detection unit 323, and the first detection unit 321 is arranged closer to the rotating disk 21 than the third detection unit 323.

[0074] In this embodiment, if Figure 2 and Figure 7 As shown, the infrared detection module 32 includes a transmitting end and a receiving end, and an emitting point for emitting detection light is formed on the transmitting end, and the emitting point includes at least one of a first type of emitting point, a second type of emitting point and a third type of emitting point. The receiving end is spaced apart from the transmitting end, and a receiving point is formed on the receiving end, and the receiving point is arranged opposite to the emitting point, wherein the receiving point arranged opposite to the first type of emitting point is a first type of receiving point, and the first type of receiving point is used to receive the detection light emitted by the first type of emitting point to determine the thickness of the detected test tube 7, the receiving point arranged opposite to the second type of receiving point is a second type of receiving point, and the second type of receiving point is used to receive the detection light emitted by the second type of emitting point to determine the length of the detected test tube 7, and the receiving point arranged opposite to the third type of emitting point is a third type of receiving point, and the third type of receiving point is used to receive the detection light emitted by the third type of emitting point to determine whether the detected test tube 7 has a hat.

[0075] Among them, the emitting point is used to emit detection light, and the receiving point is used to receive detection light. When a test tube 7 passes through the detection channel, the detection light will be absorbed and reflected by the test tube 7, resulting in the light received by the receiving point being less than the light emitted by the transmitting end. Therefore, it is possible to determine whether there is a test tube 7 passing through the detection channel by monitoring the amount of light received by the receiving point.

[0076] The first type of emitting points and the first type of receiving points are arranged at intervals along the length direction perpendicular to the test tube 7. When the test tube 7 passing through is a thick tube, the detection light emitted by all the first type of emitting points will be blocked by the test tube 7. When the test tube 7 passing through is a thin tube, only part of the detection light emitted by the first type of emitting points is blocked. Therefore, it can be judged whether the detected test tube 7 is a thick tube or a thin tube by the number of blocked first type of emitting points.

[0077] The second type of emitting points and the second type of receiving points are arranged at intervals along the length direction of the test tube 7. When the test tube 7 passing through is a long tube, the detection light emitted by all the second type of emitting points will be blocked by the test tube 7. When the test tube 7 passing through is a short tube, only the detection light emitted by the second type of emitting points at the bottom will be blocked by the test tube 7. Therefore, it can be judged whether the detected test tube 7 is a long tube or a short tube by the number of the blocked second type of emitting points.

[0078] The heights of the third type of emitting points and the third type of receiving points are determined according to the height of the test tube 7 after being capped. When the test tube 7 passing through is capped, the detection light emitted by the third type of emitting points will be blocked by the cap. When the test tube 7 passing through is not capped, the detection light emitted by the third type of emitting points will not be blocked. Therefore, by monitoring whether the third type of emitting points are blocked, it can be determined whether the test tube 7 being detected is capped or not.

[0079] In summary, the detection device 100 of the utility model forms a number of emitting points on the emitting end, forms a corresponding number of receiving points on the receiving end, and sets each emitting point opposite to a receiving point, and emits detection light to the receiving point through the emitting point. When the test tube 7 passes through the emitting end and the receiving end, the detection light emitted by some emitting points will be blocked by the test tube 7. When the first type of emitting points are all blocked by the test tube 7, the detected test tube 7 is judged to be a thick tube, otherwise, the detected test tube 7 is judged to be a thin tube; when the second type of emitting points are all blocked by the test tube 7, the detected test tube 7 is judged to be a long tube, otherwise, the detected test tube 7 is judged to be a short tube; when the third type of emitting points are blocked by the test tube 7, it is judged that the detected test tube 7 has a cap, otherwise, it is judged that the detected test tube 7 has no cap, thereby determining the type of the detected test tube 7.

[0080] Obviously, the detection method adopted by the detection device 100 overcomes the problem that conventional photoelectric detection cannot identify the length, thickness and presence or absence of a cap of the test tube 7, and compared with the visual detection method, it does not need to rely on visual algorithms and high-definition cameras, etc., has a simple structure, low cost, and can be widely used.

[0081] The first type of emitting points includes a first emitting point, a second emitting point and a third emitting point, and the first emitting point, the second emitting point and the third emitting point are arranged at intervals along the width direction of the emitting end. Correspondingly, the first type of receiving points includes a first receiving point, a second receiving point and a third receiving point, and the first receiving point is arranged opposite to the first emitting point, the second receiving point is arranged opposite to the second emitting point, and the third receiving point is arranged opposite to the third emitting point. When the detection light received by the first receiving point, the second receiving point and the third receiving point is less than the preset value, the detected test tube 7 is judged to be a thick tube, otherwise, the detected test tube 7 is judged to be a thin tube.

[0082] Among them, the first emission point, the second emission point and the third emission point are arranged in sequence from left to right, and according to the design width, no matter the test tube 7 passing through is a thick tube or a thin tube, the detection light emitted by the second emission point will be blocked by the test tube 7. When a thick tube passes through the detection channel, the detection light emitted by the first emission point, the second emission point and the third emission point will be blocked by the test tube 7, then when the light received by the first receiving point is less than the light emitted by the first emission point, and the light received by the second receiving point is less than the light emitted by the second emission point, and the light received by the third receiving point is less than the light emitted by the third emission point, it can be judged that the test tube 7 passing through is a thick tube.

[0083] When the capillary tube passes through the detection channel, only the detection light emitted by two of the emission points will be blocked by the test tube 7, that is, the detection light emitted by the first emission point and the second emission point will be blocked by the test tube 7, and the detection light emitted by the third emission point will not be blocked by the test tube 7; or, the detection light emitted by the second emission point and the third emission point will be blocked by the test tube 7, and the detection light emitted by the first emission point will not be blocked by the test tube 7. Therefore, when the light received by the first receiving point is less than the light emitted by the first emission point, and the light received by the second receiving point is less than the light emitted by the second emission point, and the light received by the third receiving point is consistent with the light emitted by the second emission point, it can be determined that the detected test tube 7 is a capillary tube. Or, when the light received by the second receiving point is less than the light emitted by the second emission point, and the light received by the third receiving point is less than the light emitted by the third emission point, and the light received by the first receiving point is consistent with the light emitted by the first emission point, it can also be determined that the detected test tube 7 is a capillary tube.

[0084] In one embodiment of the utility model, the second type of emitting points includes a fourth emitting point and a fifth emitting point, the fourth emitting point and the fifth emitting point are arranged at intervals along the height direction of the emitting end, and the fifth emitting point is located above the fourth emitting point. Correspondingly, the second type of receiving points includes a fourth receiving point and a fifth receiving point, the fourth receiving point is arranged opposite to the fourth emitting point, and the fifth receiving point is arranged opposite to the fifth emitting point. When the detection light received by the fourth receiving point and the fifth receiving point is less than a preset value, the detected test tube 7 is judged to be a long tube, and when the detection light received by the fourth receiving point is less than a preset value and the detection light received by the fifth receiving point reaches a preset value, the detected test tube 7 is judged to be a short tube.

[0085] Among them, the height of the fourth launch point is determined according to the height of the short tube, and the height of the fifth launch point is determined according to the height of the long and short tube, so that when the short tube passes, it can block the fourth launch point but cannot block the fifth launch point, and when the long tube passes, it can block both the fourth and fifth launch points.

[0086] Therefore, when the light received by the fourth receiving point is less than the light emitted by the fourth emitting point, and the light received by the fifth receiving point is less than the light emitted by the fifth emitting point, it can be judged that the test tube 7 passed by is a long tube; when the light received by the fourth receiving point is less than the light emitted by the fourth emitting point, and the light received by the fifth receiving point is consistent with the light emitted by the fifth emitting point, it can be judged that the test tube 7 passed by is a short tube.

[0087] Furthermore, the third type of emitting point includes a sixth emitting point and a seventh emitting point, the sixth emitting point is arranged between the fourth emitting point and the fifth emitting point, and the seventh emitting point is arranged above the fifth emitting point. Correspondingly, the third type of receiving point includes a sixth receiving point and a seventh receiving point, the sixth receiving point is arranged opposite to the sixth emitting point, and the seventh receiving point is arranged opposite to the seventh emitting point. When the detection light received by the sixth receiving point is less than a preset value, it is judged that the detected short tube has a cap, otherwise, it is judged that the detected short tube has no cap; when the detection light received by the seventh receiving point is less than a preset value, it is judged that the detected long tube has a cap, otherwise, it is judged that the detected long tube has no cap.

[0088] Among them, the height of the sixth emission point matches the height of the short tube after being covered with a cap, and the height of the seventh emission point matches the height of the long tube after being covered with a cap, so that when the short tube, uncapped test tube 7 passes by, the sixth emission point is not blocked, and when the short tube, capped test tube 7 passes by, the sixth emission point may be blocked by the cap; similarly, when the long tube, uncapped test tube 7 passes by, the seventh emission point is not blocked, and when the long tube, capped test tube 7 passes by, the seventh emission point may be blocked by the cap.

[0089] Therefore, when the light received by the fourth receiving point and the sixth receiving point is less than the light emitted by the emission point, and the light received by the fifth receiving point and the seventh receiving point is consistent with the light emitted by the emission point, it can be judged that the test tube 7 passed by is a short tube with a cap. When the light received by the fourth receiving point is less than the light emitted by the fourth emission point, and the light received by the sixth receiving point is consistent with the light emitted by the sixth emission point, and the light received by the fifth receiving point and the seventh receiving point is consistent with the light emitted by the emission point, it can be judged that the test tube 7 passed by is a short tube without a cap. When the light received by the fifth receiving point and the seventh receiving point is less than the light emitted by the emission point, it can be judged that the test tube 7 passed by is a long tube with a cap. When the light received by the fifth receiving point is less than the light emitted by the fifth emission point, and the light received by the seventh receiving point is consistent with the light emitted by the seventh emission point, it can be judged that the test tube 7 passed by is a long tube without a cap.

[0090] It can be understood that, in the present invention, when the test tube 7 passes between the transmitting end and the receiving end, the detection light emitted by some of the emission points will be blocked by the test tube 7. The thick tube has a larger diameter and can block the detection light emitted by the first type of emission point, while the thin tube has a smaller diameter and cannot completely block the detection light emitted by the first type of emission point; similarly, the long tube has a longer height and can completely block the detection light emitted by the second type of emission point, while the short tube is shorter and cannot completely block the detection light emitted by some of the second type of emission points; similarly, the capped test tube 7 is longer than the capless test tube 7. When the test tube 7 has a cap, it can block the detection light emitted by the third type of emission point, and when the test tube 7 has no cap, it cannot block the detection light emitted by the third type of emission point. Therefore, the length, thickness and presence or absence of a cap of the test tube 7 can be conveniently detected by checking whether the receiving point corresponding to the emission point receives the detection light, and compared with the visual detection method, it does not need to rely on visual algorithms and high-definition cameras, etc., has a simple structure, low cost, and can be widely used.

[0091] In one embodiment, the detection device 100 also includes a loading detection component 4 and a unloading detection component 5, and the loading detection component 4 and the unloading detection component 5 are arranged on the support seat 1; the test tube detection component 3 is located between the loading detection component 4 and the unloading detection component 5, and the loading detection component 4 and the unloading detection component 5 are used to detect the retention status of the test tubes 7 in different placement positions.

[0092] In this embodiment, if Figures 1 to 5As shown, the loading detection component 4 and the unloading detection component 5 are arranged on the support base 1, and the loading detection component 4 and the unloading detection component 5 are both infrared sensors or ultrasonic sensors, so that the loading detection component 4 is set toward one mounting hole 211, and the unloading detection component 5 is set toward the other mounting hole 211, and the loading detection component 4 and the unloading detection component 5 are arranged on both sides of the test tube detection component 3, and along the rotation direction of the rotating disk 21, pass through the loading detection component 4, the test tube detection component 3 and the unloading detection component 5 in sequence.

[0093] It can be understood that the loading detection component 4 and the unloading detection component 5 are used to detect whether there is a test tube 7 in a mounting hole 211. When the loading detection component 4 detects the presence of a test tube 7 in a mounting hole 211, the driving member 23 is controlled to drive the rotating disk 21 to rotate, and the test tube 7 in the mounting hole 211 is rotated to the test tube detection component 3, and the type of the test tube 7 is detected by the test tube detection component 3. Furthermore, when the rotating disk 21 rotates, the test tube 7 originally located at the test tube 7 detection position and has completed the test tube 7 type detection, rotates with the rotating disk 21 to the unloading detection component 5, and the unloading detection component 5 detects whether there is a test tube 7 at this position. If a test tube 7 is detected, the external transfer device (such as a robotic arm) is controlled to remove the test tube 7 to complete the entire detection process.

[0094] In one embodiment, the turntable assembly 2 further includes a driver 23 and a controller 24 . The driver 23 is disposed on the support base 1 , the rotating disk 21 is connected to the output end of the driver 23 , and the controller 24 is disposed on the support base 1 , and the controller 24 is electrically connected to the driver 23 .

[0095] In this embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the turntable assembly 2 also includes a driving member 23, and the driving member 23 is arranged on the support base 1. The driving member 23 is arranged on the support base 1. At the same time, the turntable assembly 2 also includes a coupling and a rotating shaft. The coupling is connected to the output end of the driving member 23 and the rotating shaft to transmit the power of the driving member 23 to the rotating shaft through the coupling. A turntable fixing seat is provided at the end of the rotating shaft away from the coupling. The turntable fixing seat is connected to the rotating shaft through a cotter pin. Further, the turntable fixing seat is connected to the rotating disk 21, so that the driving member 23 drives the rotating disk 21 to rotate.

[0096] At the same time, the turntable assembly 2 is also provided with a controller 24, which is arranged on the support base 1 and electrically connected to the driving member 23. By setting the number of mounting holes 211, the controller 24 can control the angle of each rotation of the driving member 23. When four mounting holes 211 are provided, for example, the controller 24 controls the driving member 23 to rotate 1 / 4 of a circle each time, that is, drives the rotating disk 21 to rotate 90 degrees each time, so that the four test tubes 7 arranged on the rotating disk 21 can enter different areas and positions at the same time, so as to perform operations such as loading, unloading, detection, analysis, and identification on the test tubes 7.

[0097] It can be understood that the detection device 100 is formed with a loading position, a detection position and a unloading position, and the loading position, the detection position and the unloading position are arranged corresponding to the rotating disk 21, so that at the same time, among the multiple mounting holes 211 arranged on the rotating disk 21, there is at least one mounting hole 211 corresponding to the loading position, at least one mounting hole 211 corresponding to the detection position and at least one mounting hole 211 corresponding to the unloading position, and a robotic arm or other transfer device is arranged on the outside, which can realize the loading of the test tube 7 onto the mounting hole 211 of the rotating disk 21, or the grabbing of the test tube 7 from the mounting hole 211 of the rotating disk 21.

[0098] Furthermore, the detection position is arranged between the loading position and the unloading position, that is, the rotating disk 21 drives the test tube 7 to rotate in the order of the loading position, the detection position and the unloading position, so as to realize the entire process of loading, detecting and unloading the test tube 7. The above-mentioned test tube detection component 3 is arranged corresponding to the detection position, and the above-mentioned loading detection component 4 is arranged corresponding to the loading position to detect whether the test tube 7 has been installed in the mounting hole 211 on the rotating disk 21 at the loading position, and the above-mentioned unloading detection component 5 is arranged corresponding to the unloading position to detect whether there is a test tube 7 in the mounting hole 211 on the rotating disk 21 at the unloading position.

[0099] Among them, the loading detection component 4 and the unloading detection component 5 are both electrically connected to the controller 24. When the loading detection component 4 detects that there is a test tube 7 at the loading position of the rotating disk 21, the detection signal is transmitted to the controller 24, and the driving member 23 is controlled to rotate by the controller 24, and the rotating disk 21 is driven to rotate, so as to transfer the test tube 7 at the loading position to the detection position, and the type of the test tube 7 is detected by the test tube detection component 3; at the same time, when the mounting hole 211 carrying the test tube 7 enters the detection position, a mounting hole 211 not carrying the test tube 7 is synchronously rotated to the loading position, and the test tube 7 is installed in the mounting hole 211 through an external transfer device.

[0100] When the loading detection component 4 detects that a new test tube 7 is placed in the mounting hole 211 of the rotating disk 21, the driving member 23 is controlled to rotate, and the rotating disk 21 carrying two test tubes 7 rotates. At this time, the test tube 7 located at the detection position rotates to the unloading position, and the test tube 7 located at the loading position is transferred to the detection position. When the test tube 7 enters the unloading position, the unloading detection component 5 detects that a test tube 7 has entered, and then controls the sample transport device to take out the test tube 7 located at the unloading position of the rotating disk 21, so as to complete the transport, detection and identification of the test tube 7, and effectively improve the overall transport and detection efficiency of the test tube 7.

[0101] Of course, a capping position can also be set on the rotating disk 21, and the capping position is set between the loading position and the detection position. If the loading detection component 4 detects that the test tube 7 is not capped, the test tube 7 is capped as needed. The capping method can be to manually cap the test tube 7, or a capping structure can be set. The capping structure includes a visual positioning camera and a capping operating arm. The capping structure is electrically connected to the loading detection component 4. When it is detected that the test tube 7 is not capped, the position of the mouth of the test tube 7 can be identified by the visual positioning camera, and the test tube cap can be picked up by the capping operating arm and automatically capped to the mouth of the test tube 7.

[0102] In one embodiment, the detection device 100 further includes an origin detection component 6, which includes a photoelectric sensor 61 and a sensing sheet 62. The photoelectric sensor 61 is disposed on the support seat 1, and the sensing sheet 62 is disposed on the side of the rotating disk 21 facing the support seat 1. The sensing sheet 62 can rotate with the rotating disk 21 and trigger the photoelectric sensor 61. It can be understood that if Figure 2 and Figure 4 As shown, the photoelectric sensor 61 is arranged on the support seat 1 and is electrically connected to the controller 24. The sensing sheet 62 rotates with the rotating disk 21. After the sensing sheet 62 rotates one circle with the rotating disk 21, the sensing sheet 62 will pass over the photoelectric sensor 61 again. At this time, the sensing sheet 62 blocks the photoelectric sensor 61. The photoelectric sensor 61 recognizes the signal and informs the controller 24 that the rotating disk 21 rotates to the initial position at this time.

[0103] Optionally, the detection device 100 is further provided with a memory, which is electrically connected to the test tube detection component 3, and the memory is used to store the detection results of the test tube detection component 3. It can be understood that the memory is electrically connected to the test tube detection component 3. After the test tube detection component 3 detects and identifies the length, thickness, and presence or absence of a tube cap of the test tube 7, the test tube detection component 3 will transmit the above information to the memory and store it through the memory. When the information of the sample in the test tube 7 needs to be retrieved later, or when the test tube 7 is photographed, classified, or the cap is removed, the information and data in the memory can be retrieved through the controller 24, so as to improve the intelligence of the overall management of the test tube 7 in the sample detection instrument and make the detection system more accurate and efficient.

[0104] The sample transfer device is set corresponding to the loading position and the unloading position. The sample transfer device can insert the test tube 7 into the mounting hole 211 of the rotating disk 21 at the loading position. At the same time, the sample transfer device can also take the test tube 7 out of the mounting hole 211 of the rotating disk 21 at the unloading position to realize the loading and unloading of the test tube 7.

[0105] The present invention also provides a sample analyzer, which includes a sample analysis device, a sample transport device and the above-mentioned detection device 100, wherein the sample transport device is used to transfer the sample to the detection device 100, and to transfer the sample from the detection device 100 to the sample analysis device.
