[0033] The technical solution of the present utility model will be further described below with specific embodiments, but the protection scope of the present utility model is not limited to the following embodiments.

[0034] Embodiment 1: As Figures 1 to 6As shown in the figure, this pre-treatment track module includes a frame 1, a belt conveyor module 2 arranged on the frame 1, a track replacement module 3 arranged at the downstream end of the belt conveyor module 2, a toothed belt precise conveying module 4, a blocking and pushing module 5 and a limiting module 6 arranged on the belt conveyor module 2. Among them, the belt conveyor module 2 includes a normal track 201, an emergency track 202 and a recovery track 203 formed by being isolated by side baffles 21. A transmission belt 22 and a pulley 23 for driving the transmission belt 22 are provided in each of the normal track 201, the emergency track 202 and the recovery track 203. Detection position elongated slots 24 are provided on the side baffles 21 of the normal track 201 and the emergency track 202; the toothed belt precise conveying module 4 includes a conveying claw assembly 41 and a toothed belt track assembly 42. The conveying claw assembly 41 includes a claw frame 411, a conveying claw 412 slidably fitted on the claw frame 411, and a stepping motor 413 fixed on the claw frame 411 and used to drive the conveying claw 412 to translate; the toothed belt track assembly 42 includes a synchronous toothed belt 421, a gear driving motor 422 for driving the synchronous toothed belt 421, and a guiding track 423 for guiding the movement of the claw frame 411; the toothed belt precise conveying module 4 is arranged on the frame 1 and located in the corresponding area of the detection position elongated slot 24. The claw frame 411 is slidably assembled on the guiding track 423. One side of the claw frame 411 is connected to a drag chain 424 on the synchronous toothed belt 421. The stepping motor 413 is engaged with a translation tooth part below the conveying claw 412 through a translation gear mounted on the output shaft. The structure of this module integrates a belt drive system and a gear drive system, and the whole is assembled with modular components. During operation, when reagents are respectively contained in test tubes on a reagent rack and are transported to the normal track or the emergency track through a trolley module, the pulleys in the normal track or the emergency track start the transmission belt to drive the reagents to the detection position in the area of the detection position elongated slot; the toothed belt precise conveying module starts. The conveying claw translates inwards under the drive of the stepping motor, passes through the detection position elongated slot to clamp the reagent rack, and precisely conveys the test tube rack in the way of driving the synchronous toothed belt by a gear and then transmitting it to the claw frame to complete the sampling and detection; after the detection is completed, the stepping motor drives the conveying claw to translate outwards to release the test tube rack, and the test tube rack travels again under the belt conveyor; it reaches the track replacement module to replace the track and is adjusted to the recovery track for recovery.

[0035] Embodiment 2: As Figures 7 to 9As shown in the figure, the push-block module 5 of the present pre-treatment track module is arranged on the rack 1 and is located downstream of the recycling track 203. The push-block module 5 includes a push-block frame 51, a moving guide rail 52, and a driving toothed belt 53. The middle part of the push-block frame 51 is slidably assembled on the moving guide rail 52 through a slider, and the lower end of the push-block frame 51 is connected to the driving toothed belt 53. A push head 511 is provided on the push-block frame 51, and the push head 511 is rotatably connected to the upper end of the push-block frame 51 through a torsion spring. The push-block module on the downstream section of the recycling track is used to block, release, and push the incoming reagent rack, while isolating the subsequent reagent racks and pushing the front reagent rack to the recycling position at the required speed. A limit groove 211 is opened on the side baffle 21 inside the recycling track 203, and the limit module 6 is installed on the rack 1 and is located at the corresponding position of the limit groove 211. The limit module 6 includes a bent-arm stopper 61 and a blocking motor 62 for driving the bent-arm stopper 61 to extend into the limit groove 211. Under the recognition function of the detection module, the test tube rack moving downward on the recycling track is blocked and its downstream transportation is restricted, preventing the test tube racks from being pushed and squeezed downstream in case of untimely recycling, so that the push-block module loses its control function due to overload. The track replacement module 3 includes a short track 31 for accommodating the test tube rack, a translation frame 32, a transverse movement guide rail 33, and a transverse movement toothed belt 34. The short track 31 is installed above the translation frame 32, the outer side of the bottom of the translation frame 32 is slidably assembled on the transverse movement guide rail 33 through a slider, and the inner side of the bottom of the translation frame 32 is connected to the transverse movement toothed belt 34. The test tube racks on the normal track or the emergency track are transported into the short track, and the transverse movement toothed belt drives the translation frame to move horizontally along the transverse movement guide rail to release the test tube rack to the recycling track, completing the track replacement of the test tube rack after inspection. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0036] Embodiment 3: As Figure 10 , 11 shown in the figure, the present pre-treatment track module further includes a main control circuit module 7 installed on the rack 1 for controlling the operation of each motor, and a detection module 8 installed on the side baffle 21 of the recycling track 203 for identifying the position of the test tube rack.

The main control circuit module is used to connect to an external control host computer, program the orderly start and stop of each motor, and perform closed-loop feedback automatic control according to the signals of the detection module. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0037] The present pre-treatment track module integrates friction drive and gear drive, and adopts a modular component design according to functions and an overall assembly form. On the basis of improving the conveying efficiency and the stability of the conveying position of reagent detection, it is convenient to perform separate maintenance and repair and component replacement for functional parts, taking into account both reliability and efficiency.
