[0045] In the medical industry, sample tubes, reaction cups and other containers are usually used as carriers for samples or reagents to test samples.

[0046] During use, the sample or reagent carrier needs to be fixed and placed by a cuvette carrier. For example, during the transportation of the cuvette, the cuvette needs to be placed on the cuvette carrier, and then the cuvette carrier carrying the cuvette is placed on the track of the medical automation equipment, so as to achieve automatic filling of the sample. The track of the medical automation equipment usually includes an inner track and an outer track arranged in parallel. When the cuvette carrier needs to switch between the inner and outer tracks, it needs to pass through the track changing device connecting the inner track and the outer track for intermediate transition and transportation.

[0047] When the reaction cup carrier enters the track changing device from the inner track and leaves the track changing device to enter the outer track, that is, when changing direction, due to the gap between the inner track and the track changing device, and between the outer track and the track changing device, the reaction cup carrier does not run stably during the above-mentioned switching process, and the switching is not smooth.

[0048] In order to solve the above problems, the utility model proposes a track changing device, which aims to provide a track changing device that makes the reaction cup change direction more smoothly. Figures 1 to 8 The present invention is a schematic structural diagram of an embodiment of the track changing device provided by the present invention.

[0049] Please refer to Figures 1 to 8 The utility model proposes a track changing device 1000, including a base 1, a connector 3 and a reversing mechanism 2, the connector 3 includes a first track connector block 31 and a second track connector block 32 arranged on the base 1, the reversing mechanism 2 includes a turntable 21 and a driving member 22, the turntable 21 is rotatably arranged on the base 1, the driving end 222 of the driving member 22 is connected to the turntable 21, the first track connector block 31 and the second track connector block 32 are located on the outer periphery of the turntable 21; the upper surface of the turntable 21 is inclined, and the end of the upper surface of the turntable 21 close to the first track connector block 31 is lower than the end of the upper surface of the turntable 21 close to the second track connector block 32.

[0050] The upper surface of the turntable 21 has an end close to the first track connection block 31 lower than the upper surface of the first track connection block 31 , and the upper surface of the turntable 21 has an end close to the second track connection block 32 higher than the upper surface of the second track connection block 32 .

[0051] It should be noted that the driving member 22 for driving the turntable 21 to rotate can be an electric motor or an air motor, and the present invention does not impose any restrictions on this. In one embodiment of the present invention, the driving member 22 is a driving motor 221, and a driving end 222 is provided at one end of the driving motor 221 facing the turntable 21, and the driving end 222 of the driving motor 221 is connected to the disk 211 below the turntable 21, and a fixed shaft 211a connected to the driving end 222 is formed on the disk 211. The driving motor 221 can provide a stable rotation speed and adjustable rotational force, and can be adjusted and controlled according to the precise speed required by different types of solutions; secondly, the driving motor 221 has high efficiency and high power output, and can provide sufficient power to drive a larger and heavier turntable 21; in addition, the use of the driving motor 221 can also realize automation and remote control, thereby improving the convenience and flexibility of line transmission.

[0052] Specifically, in order to realize the inclined installation of the turntable 21, the drive motor 221 needs to be installed at an inclined angle. In one embodiment of the present utility model, the lower surface of the base 1 is an inclined plane. For details, please refer to Figure 4 The driving motor 221 is integrally arranged on the inclined lower surface of the base 1. The base 1 is provided with a through hole (not marked in the figure). The driving end 222 of the driving motor 221 passes through the through hole until it is installed with the fixed shaft 211a of the disk 211. Since the disk 211 and the turntable 21 are installed on the driving motor 221, they both maintain the same inclination angle with the driving motor 221, so that the upper surface of the turntable 21 for transporting the reaction cup carrier is inclined.

[0053] In another embodiment of the utility model, the lower surface of the base 1 is horizontally arranged, and the driving motor 221 is installed on the lower surface of the base 1 by fixing bolts at the four corners. The two bolt sleeves of the driving motor 221 close to the first track connecting block 31 are provided with washers so that the driving motor 221 is inclined relative to the lower surface of the base 1, thereby making the turntable 21 connected to the driving end 222 of the driving motor 221 inclined, and can also achieve the same technical effect as the above embodiment.

[0054] In the technical solution of the utility model, a track changing device 1000 and a medical laboratory automation device 2000 are proposed, wherein the track changing device 1000 includes a base 1, a reversing mechanism 2 and a connecting piece 3, the base 1 is used to connect the ends of the inner track 2200 and the outer track 2300 respectively, the reversing mechanism 2 includes a turntable 21 and a driving member 22, the turntable 21 is rotatably arranged on the base 1, and the upper surface of the turntable 21 is inclined so that the upper surface of the turntable 21 is close to the first track connecting block 31 and is lower than the upper surface of the turntable 21 close to the second track connecting block 3 2, by tilting the turntable 21 at a certain angle, so that the first track connecting block 31 of the connecting member 3 is slightly higher than the upper surface of the turntable 21, and the upper surface of the turntable 21 is slightly higher than the second track connecting block 32, the reaction cup carrier can smoothly enter the reversing turntable 21 under the action of gravity, and the reaction cup carrier will be smoother when entering the turntable 21 at the position of the first track connecting block 31, and correspondingly, it will be smoother when leaving the turntable 21 and moving to the position of the second track connecting block 32, thereby reducing the possibility of splashing of the solution in the reaction cup due to uneven reversing.

[0055] Since the first track connecting block 31 and the second track connecting block 32 need to be connected to the inner track 2200 and the outer track 2300 respectively at the end facing away from the turntable 21, the upper surfaces of the first track connecting block 31 and the second track connecting block 32 need to be kept horizontal so that the transition of the reaction cup carrier from the inner track 2200 to the first track connecting block 31 and from the second track connecting block 32 to the outer track 2300 is relatively smooth without fluctuations due to the existence of angles. In order to achieve the horizontal setting of the upper surfaces of the first track connecting block 31 and the second track connecting block 32, the upper surface of the base 1 is formed with a mounting plane 1a. For details, please refer to Figure 1 and Figure 4 The first track connecting block 31 and the second track connecting block 32 are movably arranged on the installation plane 1a. The installation of the first track connecting block 31 and the second track connecting block 32 is realized by using the installation plane 1a as the reference plane, so that the upper surfaces of the first track connecting block 31 and the second track connecting block 32 are horizontally arranged, thereby maintaining a smooth connection with the inner and outer tracks 2300 and reducing the shaking of the reaction cup carrier.

[0056] Further, in order to improve the universality of the device, that is, to meet the transmission of more different types of solutions, the connector 3 also includes a plurality of adjustment members 33, which can be adjustment bolts or adjustment gaskets. The present invention does not limit this. In one embodiment of the present invention, two adjustment bolts are provided under each track connector block, which are fixed to the base 1 by the two adjustment bolts. For details, please refer to Figure 4 When it is necessary to fine-tune one of the track connection blocks, the adjusting bolt can be screwed from the lower surface of the base 1 to make the adjusting bolt rise upward or retract downward, so that the height difference between the adjusted track connection block and the turntable 21 and the inner and outer tracks 2300 can be further changed. When the device transports a solution with good fluidity and low density, the height difference between the track connection block and the turntable 21 can be further adjusted to reduce it, thereby preventing the generation of splashing liquid; when the device transports a solution with poor fluidity and high viscosity, the height difference between the track connection block and the turntable 21 can be further adjusted to increase it, thereby making the transition of the reaction cup carrier smoother. Furthermore, the two adjusting bolts can share the gravity of the track connection block, thereby reducing the slight movement caused by the overall vibration of the device. The two adjusting bolts can also provide double self-locking protection to prevent the adjusting bolts from slipping.

[0057] In order to ensure that the inclination of the turntable 21 is within a reasonable inclination range and to avoid serious wall hanging caused by the flow of the solution due to the excessive inclination of the turntable 21, the angle between the upper surface of the turntable 21 and the mounting plane 1a is in the range of 0.6° to 0.8°. In one embodiment of the utility model, the angle α between the upper surface of the turntable 21 and the mounting plane 1a is 0.6°. For details, please refer to Figure 5 When the angle between the upper surface of the turntable 21 and the mounting plane 1a is 0.6°, the transition between the connecting block and the turntable 21 can be smoother while ensuring that the solution does not stick to the wall. When the upper surface of the turntable 21 is inclined at 0.6°, the height difference between the upper surface of the first track connecting block 31, the upper surface of the second track connecting block 32 and the turntable 21 is 0.2 mm, so that the reaction cup carrier can switch from the inner track 2200 to the outer track 2300 more smoothly.

[0058] In one embodiment of the utility model, in order to achieve a smooth transition between the track and the track connecting block, the upper surface of the first track connecting block 31 is lower than the inner track 2200, and correspondingly, the upper surface of the second track connecting block 32 is higher than the outer track 2300. Specifically, there is a height difference of 0.2 mm between the first track connecting member 3 and the inner track 2200, and there is a height difference of 0.2 mm between the second track connecting member 3 and the outer track 2300. The reaction cup carrier passes smoothly through the gap between the track and the track connecting member 3 under the action of gravity.

[0059] In order to further make the transition of the cuvette carrier between the track connection block and the turntable 21 smoother, the first track connection block 31 is provided with arc transition portions 311 at both ends close to the turntable 21 and the inner track 2200. For details, please refer to Figure 6 , the provision of the circular arc transition portion 311 can reduce the damage and wear of the sharp edges on the reaction cup carrier, especially in the case of frequent contact, avoiding possible collisions or scratches. Secondly, by chamfering the edges of the track connection block, a smoother transition angle can be achieved, so that the transition of the reaction cup carrier when contacting or passing through the track connection block is smoother. This helps to reduce vibration and impact, and improve the stability and reliability of the overall device. In addition, the circular arc transition portion 311 can also reduce stress concentration, avoid the occurrence of cracks and fractures, and extend the service life of the track connection block. Correspondingly, the end of the second track connection block 32 close to the turntable 21 is also provided with an arc transition portion 311, so that the reaction cup carrier can be smoother when the second track connection block 32 transitions to the side of the outer track 2300 after switching from the turntable 21.

[0060] In order to install the track changing device 1000 at the ends of the inner track 2200 and the outer track 2300, a connecting member 11 is provided on the side of the base 1 facing the inner track 2200 and the outer track 2300. For details, please refer to Figure 2 and Figure 3 , the connecting piece 11 is a connecting column. The installation of the track changing device 1000 is achieved by inserting the connecting piece 11 into the connecting hole at the end of the track. The connecting column and the connecting hole are interferingly fit to achieve clamping and fixing. The interference fit can provide stronger connection strength and rigidity, and ensure the firmness and stability of the connection. Secondly, the interference fit can eliminate the gap at the connection, reduce looseness and vibration during movement, and improve the accuracy and reliability of the device. In addition, the interference fit can also share the load of the connecting components, reduce the load of a single component, and extend the service life of the entire connection system. In summary, the connection achieved by using an interference fit between the connecting column and the connecting hole has higher strength, stability, accuracy and reliability, and can provide a load sharing effect.

[0061] In order to achieve precise positioning of the track changing device 1000 when it is connected to the ends of the two tracks, a guide member 12 is further provided on the side of the base 1 facing the inner track 2200 and the outer track 2300. A guide groove 12a is axially formed at the end of the guide member 12. The guide member 12 cooperates with the guide hole at the end of the track to achieve precise docking and guiding, thereby preventing incorrect or reverse installation.

[0062] In order to prevent the reaction cup carrier from shifting under the action of centrifugal force, the upper bottom wall of the disk 211 is provided with an anti-slip layer 212. For details, please refer to Figure 1First, the anti-skid layer 212 can increase the friction between the cuvette carrier and the disc 211, prevent the cuvette carrier from sliding or falling during movement, and ensure that the cuvette carrier can stay stably on the disc 211. This helps to improve the transmission efficiency of the turntable 21 and reduce the probability of damage to the cuvette carrier. Secondly, the anti-skid layer 212 can provide an additional protective layer to prevent direct contact between the cuvette carrier and the disc 211, reduce wear and damage to the cuvette carrier, and extend the service life of the cuvette carrier. In addition, the anti-skid layer 212 can also reduce noise and vibration, improve the working environment and operating experience. It should be noted that the anti-skid layer 212 can be integrally formed with the disc 211, or can be bonded to the upper surface of the disc 211 by bonding. The present invention does not limit this. In one embodiment of the present invention, the anti-skid layer 212 uses a rubber pad, which is bonded to the surface of the disc 211. The rubber pad has good anti-skid performance and can increase the friction between the cuvette carrier and the disc 211 to prevent the cuvette carrier from sliding or falling during movement. Specifically, the friction coefficient of the anti-skid layer 212 is above 0.5, so that sufficient friction can be provided to prevent the cuvette carrier from slipping, tilting, etc.

[0063] In order to prevent the cuvette carrier from being thrown out of the disk 211 or shifting sideways due to the centrifugal force generated by the rotation of the disk 211, the track changing device 1000 further includes a first guide plate 41. For details, please refer to Figure 1 and Figure 2 The two ends of the first guide plate 41 are respectively arranged at the first track connection block 31 and the second track connection block 32, and are located in the circumference of the disc 211, and form an opening toward the two tracks. The first guide plate 41 is U-shaped as a whole. When the reaction cup carrier is offset toward the circumference of the disc 211 by the centrifugal force, the first guide plate 41 can support the reaction cup carrier and provide lateral support. The first guide plate 41 can effectively guide the reaction cup carrier to maintain a stable motion trajectory at the bend, and prevent the reaction cup carrier from deviating from the original path due to the centrifugal force. This helps to reduce the friction and loss of the reaction cup carrier and maintain the transmission efficiency of the reversing mechanism 2. Secondly, the first guide plate 41 can provide additional support and constraints to prevent the reaction cup carrier from tilting or rolling at the reversing point, thereby ensuring the safe transmission of the reaction cup carrier. In addition, the first guide plate 41 can also balance the center of gravity distribution of the reaction cup carrier, reduce the instability of the reaction cup carrier at the bend, and improve the stability and reliability of the switching mechanism 2. By using the first guide plate 41, the movement trajectory of the reaction cup carrier can be effectively controlled at the bend, reducing deviation and loss, and ensuring the safe and stable transmission of the reaction cup carrier.

[0064] The guide portion 4 further includes a second guide plate 42. For details, please refer to Figure 2The second guide plate 42 is spaced apart from the first guide plate 41. The second guide plate 42 is arranged on the base 1 through the fixing plate 5 and is located on the inner circumference of the disc 211. In order to install the second guide plate 42, the turntable 21 also includes a pressure plate, which is arranged on the fixed shaft 211a and abuts against the disc 211. The axis of the pressure plate coincides with the axis of the disc 211. The pressure plate is provided with four pressure plate screws 213a, and the pressure plate fixes the disc 211 to the driving end 222 of the driving motor 221 through the four pressure plate screws 213a.

[0065] The utility model also provides a medical laboratory automation device 2000, which includes an inner track 2200, an outer track 2300 and a track changing device 1000. For details, please refer to Figure 3 and Figure 4On one side of the inner track 2200, a plurality of workstations for achieving different functions are arranged, which mainly include a cup supply station 2500, a sample filling station 2400 and a measurement unloading station 2600. The overall working principle of the medical laboratory automation equipment 2000 is as follows: when a reaction cup carrier is placed in the loading area of ​​the track module and the clamping and limiting mechanism of the reaction cup carrier is reset at the beginning, the inner track 2200, the outer track 2300 and the track changing device 1000 are started, that is, the conveyor belts of the inner track 2200 and the outer track 2300 are moving in the set direction. Therefore, when the cuvette carrier is transported by the conveyor belt of the inner track 2200 and moves to the cup supply station 2500, the detection device for detecting whether the cuvette carrier has a problem is triggered, and the clamping and limiting mechanism of the cuvette carrier performs the limit clamping on the cuvette carrier, and the gripper mechanism in the analyzer 2100 will move the container from the cup supply station 2500 to the cuvette carrier. When the detection device for detecting whether the container on the cup supply station 2500 has a problem is triggered, the clamping and limiting mechanism of the cuvette carrier releases the cuvette carrier, so that the cuvette carrier is on the inner track 220 0, the cuvette carrier is transported to the sample filling station 2400. When the detection device of the sample filling station 2400 detects the cuvette carrier and the cuvette, the cuvette carrier limit clamping module will execute the limit clamping of the cuvette carrier and the sample loading module in the analyzer 2100 will load the cuvette. After the loading is completed, the cuvette carrier limit clamping module of the sample filling station 2400 will release the cuvette carrier, so that the cuvette carrier moves to the track changing device under the conveyance of the inner track 2200 conveyor belt. 1000, when the cuvette carrier moves to the reversing track changing device 1000, the cuvette carrier passes through the track changing device 1000 under the inertial force of the conveyor belt of the inner track 2200 during the movement, and the cuvette carrier changes track from the inner track 2200 to the outer track 2300 through the track changing device 1000, and then the conveyor belt on the outer track 2300 and the track changing device 1000 at the other end change the cuvette carrier to the inner track 2200 (at this time, the container on the cuvette carrier contains the sample). When the cuvette carrier is driven by the conveyor belt of the inner track 2200, the cuvette carrier changes direction to the outer track 2300. The reaction cup carrier moves to the measuring unloading station 2600 of the analyzer 2100. When the detection device at the measuring unloading station 2600 of the analyzer 2100 detects the reaction cup carrier, the reaction cup carrier limit clamping module performs a limit clamping action on the reaction cup carrier, and then the container grasping mechanism in the analyzer 2100 will move the container containing the sample on the reaction cup carrier to the designated position in the analyzer 2100, and the reaction cup carrier with the container unloaded moves to the cup supply station 2500 of the analyzer 2100 for re-supply of cups under the movement of the conveyor belt of the inner track 2200.
