Description

Technical Field

[0002] In order to meet the needs of higher speed and higher requirements of medical testing, biochemical immunoassay is inevitable. At present, biochemical immunoassay is widely used in many areas. The accurate transmission speed of samples in the biochemical immunoassay production line is the key to biochemical immunoassay.

[0003] The current biochemical immunology production line equipment moves rapidly during the process of transporting the sample rack and needs to stop immediately and accurately. In order to achieve an accurate and immediate stop, the belt transporting the sample rack does not move at this time, but the sample rack needs to move, so a pushing and driving device is required to make the sample rack continue to move on the stationary belt. The current biochemical immunology production line equipment usually directly uses a blocking and driving device to stop the sample rack using the friction of the belt. However, the existing blocking and driving device has the following disadvantages: since the friction between the belt transporting the sample rack and the sample rack is not constant, it is affected by factors such as the tightness, wear, lubrication condition of the belt, and the material and weight of the sample rack, which may cause the accuracy of the sample rack stop position to be low, which is not conducive to high-precision automated pre-processing operations.

The first driving mechanism drives the sample rack support plate 1 to move laterally smoothly along the transverse slide rail 8.

[0030] In the present invention, the immunoluminescence pre-treatment track refers to the track of an automated assembly line used for sample pre-treatment during immunoluminescence analysis, wherein the sample pre-treatment includes pre-treatment steps such as sample transportation, emergency transportation, and sample sampling.

[0031] Preferably, the second driving mechanism comprises a horizontal motor 9, a driving wheel 10, a driven wheel 11, a first connecting plate 12, a synchronous belt 13, a belt clamping plate 14, a second slider 15 and a second slide rail 16. The horizontal motor 9 is mounted on the main support plate 3. The driving wheel 10 and the driven wheel 11 are rotatably arranged at the two ends of the main support plate 3 respectively. The synchronous belt 13 is wound around the driving wheel 10 and the driven wheel 11. The horizontal motor 9 is connected to the driving wheel 10 in a transmission manner. One end of the first connecting plate 12 is connected to the bottom support plate 2, and the other end is connected to the synchronous belt 13. The second driving mechanism drives the sample rack support plate 1 to move precisely in the horizontal direction.

[0032] See also Figure 3Preferably, the upper end of the first connecting plate 12 is provided with a first bending portion 1201, and the first bending portion 1201 is fixedly connected to the bottom support plate 2, ensuring the stable combination of the first connecting plate 12 and the bottom support plate 2, and providing the sample rack support plate 1 with a driving force for transmitting the horizontal direction.

While the horizontal motor 9 drives the synchronous belt 13 to move, the first connecting plate 12 can drive the bottom support plate 2 to slide smoothly on the second slide rail 16 through the second slider 15, thereby achieving smooth and accurate horizontal movement of the sample rack support plate 1 in the horizontal direction.

[0033] See also Figure 3 Preferably, a sensor fixing plate 17 is fixedly arranged on the bottom support plate 2, and a first optical coupling sensor 18 for detecting the starting position of the sample rack support plate 1 and a second optical coupling sensor 19 for detecting that the sample rack support plate 1 reaches a predetermined precise positioning position are arranged on the sensor fixing plate 17; a baffle portion 102 adapted to the first optical coupling sensor 18 and the second optical coupling sensor 19 is arranged at the bottom of the sample rack support plate 1.

When the sample rack support plate 1 moves to the starting position, the baffle portion 102 at the bottom of the sample rack support plate 1 will block and trigger the first optical coupling sensor 18, thereby knowing that the sample rack support plate 1 is located at the starting position. The second optical coupling sensor 19 is used to detect whether the sample rack support plate 1 has reached the preset precise positioning position, that is, the precise position required for a specific pre-processing operation. Similarly, when the sample rack support plate 1 moves with the sample rack to the corresponding workstation, the baffle portion 102 will block and trigger the second optical coupling sensor 19, thereby confirming that the sample rack has accurately reached the preset operating position.

[0034] Please see again Figure 1Preferably, the second driving mechanism further includes a second connecting plate 20, a third optical coupling sensor 21 and a code disk 22. The second connecting plate 20 is fixedly connected to the first connecting plate 12. The third optical coupling sensor 21 is fixedly arranged on the inner side of the second connecting plate 20. The code disk 22 is fixed on the main support plate 3 and is located between the upper and lower synchronous belts 13. The third optical coupling sensor 21 is adapted to the code disk 22. The rotation of the code disk 22 is synchronized with the movement of the sample rack support plate 1. When the code disk 22 moves with the movement of the sample rack support plate 1, the notch on the code disk 22 will periodically block or expose the third optical coupling sensor 21, thereby generating a pulse signal. Each pulse represents a certain distance moved by the sample rack support plate 1. By counting the number of these pulses, the conveying, start and stop state positions of the sample rack support plate 1 can be understood and controlled in real time and accurately.

[0035] See also Figure 2 Preferably, a limit plate 23 is provided on the bottom support plate 2, and a fourth optical coupling sensor 24 is provided at the end of the main support plate 3, and the limit plate 23 is adapted to the fourth optical coupling sensor 24.

[0037] Preferably, the bottom support plate 2 is provided with a first limiting column 25 for stopping the movement of the first slider 7. The provision of the first limiting column 25, on the one hand, ensures that the sample rack support plate 1 can accurately stay at a preset position when moving horizontally, providing boundary conditions for the movement of the first slider 7, and on the other hand, effectively prevents the abnormal conditions of the first optical coupling sensor 18 and the second optical coupling sensor 19 from causing excessive movement of the first slider 7.

[0038] Preferably, the main support plate 3 is provided with a second limit post 26 for stopping the movement of the second slider 15. The second limit post 26 ensures that the sample rack support plate 1 can accurately stay at a preset position when moving horizontally, providing a boundary condition for the movement of the second slider 15, and effectively prevents the abnormal situation of the third optical coupling sensor 21 from causing excessive movement of the second slider 15.

[0039] Preferably, a third connecting plate 27 is provided on the main support plate 3, and a guide chain 28 is provided on the third connecting plate 27. The guide chain 28 can put various electrical lines such as power lines, signal lines, and data lines together in an orderly manner.

[0040] The inventive principle of the utility model is as follows:

[0041] When the track starts working, the first optical coupling sensor 18 detects that the sample rack support plate 1 is located at the starting position. When the sample rack enters the track, the transverse motor 4 drives the spline shaft 5 to rotate, the spline shaft 5 drives the transmission block 6 to move, and the transmission block 6 drives the first slider 7 to move horizontally along the transverse slide rail 8 to the track side. After the second optical coupling sensor 19 detects that the sample rack support plate 1 has reached the preset precise positioning operation position, the clamping plate part 101 clamps the sample rack, and the belt for transporting the sample rack stops working. Then, the horizontal motor 9 drives the driving wheel 10 to rotate, and then uses the synchronous belt 13 to evenly and accurately transmit the power to the driven wheel 11. The first connecting plate 12 can drive the bottom support plate 2 to slide smoothly on the second slide rail 16 through the second slider 15, thereby realizing the smooth and accurate horizontal movement of the sample rack of the sample rack support plate 1 in the horizontal direction. Under the cooperation of the third optical coupling sensor 21 and the code disk 22, the sample rack is transported and started and stopped, and can cooperate with the sampling arm to sample, achieving "stop at any time, stop accurately". When the sample pre-treatment on the sample rack is completed, the clamping plate portion 101 releases the sample rack, the belt for transporting the sample rack starts to work, and the sample rack support plate 1 returns to the starting position to repeat the previous work.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
