Description

Technical Field

[0001] The invention relates to a blood testing machine and belongs to the technical field of medical equipment. Background Art

[0002] The basic steps of a blood test are: 1. Specimen collection: a clinical nurse draws venous blood from the patient; 2. Specimen transportation: blood is immediately sent to the clinical laboratory after collection; 3. Specimen reception and processing: the laboratory adds the reagents required for testing to the specimen; 4. Testing and storage of the specimen on the machine. Each of the above steps requires the participation of professionals, so blood testing requires the participation of a large number of people. However, the participation of a large number of people does not increase the speed of testing or guarantee the accuracy of the test. Using people to transport specimens wastes labor and cannot guarantee speed. During specimen processing, the laboratory needs to add reagents according to the blood test requirements of each patient. However, manual addition can easily lead to errors such as incorrect addition and omission, resulting in abnormal test results. Summary of the Invention

[0103] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-41 As shown, the blood testing machine includes a loading device 1, a dispensing device 2, and a dispensing device 3, arranged in order from front to back on a front frame 6; and a material transfer device 4 and a testing device 5, arranged on a rear frame 8. After a blood sample is collected, a blood collection tube and other materials are placed into the loading device 1. After the loading device 1 loads the sample, the dispensing device 2 picks up the blood collection tube and other materials from the loading device 1 and moves them to a predetermined position within the dispensing device 3. The blood in the blood collection tube is sampled by the dispensing device 3, and the required test reagents are added to form a test specimen. The material transfer device 4 transfers the test specimen to the testing device 5 for blood testing.

[0104] In the above technical solution: Figure 3 As shown, the front rack 6 includes a front rack frame 61 and a storage cabinet 62 located inside the front rack frame 61. The front end of the storage cabinet 62 is provided with an opening and closing door, and first sliding doors 611 are provided on both sides of the front rack frame 61. The storage cabinet 62 is fixed to the middle part of the front rack frame 61. The top surface of the storage cabinet 62 is lower than the top surface of the front rack frame 61. A front mounting hole 63 is formed between the storage cabinet 62 and the front portion of the front rack frame 61. An L-shaped baffle 65 is provided below the front mounting hole 63. A rear mounting hole 64 is formed between the storage cabinet 62 and the rear portion of the front rack frame 61. A mating notch 612 is also formed at the rear portion of the front rack frame 61. The loading device 1 is disposed in the front mounting hole 63 and the top surface of the storage cabinet 62. The L-shaped baffle 65 provides certain protection and prevents the loading device 1 from falling. The material removal device 2 and the batching device 3 are disposed in the rear mounting hole 64. A portion of the material transfer device 4 passes through the mating notch 612 and cooperates with the batching device 3.

[0105] In the above technical solution: Figure 3 As shown, the bottom of the front frame 61 is provided with a plurality of foot cup assemblies 66 and caster assemblies 67. The foot cup assemblies 66 are responsible for positioning, and the caster assemblies 67 are responsible for movement. A foot cup mounting plate 68 is also fixed to the bottom of the front frame 61, and a through hole is formed on the foot cup mounting plate 68. Figure 37 、 38As shown, the foot cup assembly 66 includes a foot cup rod 661 with a threaded outer wall, a foot cup plate 662 is installed at the bottom of the foot cup rod 661, and the top of the foot cup rod 661 passes through the through hole and can move up and down in the front frame 61. An adjusting nut 664 is fixed on the foot cup rod 661, and a positioning nut 663 is also provided on the foot cup rod 661. The positioning nut 663 is located above the adjusting nut 664. When positioned, the positioning nut 663 is close to the bottom of the foot cup mounting plate 68. A foot cup hole 6621 is formed on the foot cup plate 662, and a fixing screw is provided in the foot cup hole 6621. The fixing screw fixes the foot cup plate 662 to the ground or the table top of the operating table to prevent the front frame 6 from moving. As shown Figure 37 、 39 As shown, the caster assembly 67 includes a caster fixing member. In this embodiment, the caster fixing member is fixed to the bottom of the foot cup mounting plate 68. The caster fixing member can also be directly fixed to the bottom of the front frame 61. Caster side panels 671 are formed downwardly on both sides of the caster fixing member. A roller 672 is provided between the two caster side panels 671. The caster side panels 671 include a flat portion 6711 and a curved portion 6712. The flat portion 6711 is formed with a pin hole. A pin 69 is provided in the pin hole. The pin 69 passes through the roller 672 and is fixed to the two caster side panels 671. The pin holes are exposed at both ends of the pin 69 and are threadedly connected to the mounting nut 610. The curved portion 6712 provides sufficient space for the roller 672 to roll, while also preventing the roller 672 from being disturbed during rolling. When the front frame 6 is fixed, the positioning nut 663 is turned with a wrench until it is tightly attached to the bottom surface of the foot cup mounting plate 68, preventing the foot cup mounting plate 68 from moving downward due to the downward pressure of the front frame 6, keeping the overall height of the front frame 6 consistent, and the fixing screw passes through the foot cup hole 6621 and is fixed to the ground or the table top of the operating table to prevent the frame from moving; when the front frame 6 needs to be moved, the fixing screw is first unscrewed from the foot cup hole 6621, and then the positioning nut 663 is turned with a wrench to make it leave the bottom surface of the foot cup mounting plate 68, and then the adjusting nut 664 is turned with the wrench. The adjusting nut 664 drives the foot cup rod 661 to rotate. During this process, the foot cup mounting plate 68 and the front frame frame 61 are all moving downward until the roller 672 contacts the ground or the table top of the operating table, stop turning the wrench, and then use the wrench to tighten the positioning nut 663 until it is tightly attached to the bottom surface of the foot cup mounting plate 68, and push the front frame 6 to achieve movement.

[0106] In the above technical solution: Figure 4 As shown, the feeding device 1 includes twelve conveying lines, namely the first blood collection tube feeding conveying line (corresponding to Figure 4 First blood collection tube inlet), first blood collection tube recovery conveying line (corresponding to Figure 4 The first blood collection tube out), the second blood collection tube feeding conveyor line (corresponding to Figure 4 The second blood collection tube in), the second blood collection tube recovery conveying line (corresponding to Figure 4The second blood collection tube in the test cup feeding conveyor line (corresponding to Figure 4 The first reagent tube feeding conveyor line (corresponding to Figure 4 The first reagent tube in the second reagent tube feeding conveyor line (corresponding to Figure 4 The second reagent tube in the glass bottle P1 feeding conveyor line (corresponding to Figure 4 P1 in), glass bottle P2 feeding conveyor line (corresponding to Figure 4 P2 / P3 in the glass bottle feeding conveyor line (corresponding to Figure 4 P2 / P3 in the small suction head feeding conveyor line (corresponding to Figure 4 Small suction head), large suction head feeding conveyor line (corresponding to Figure 4 The glass bottle P2 loading conveyor line and the glass bottle P3 loading conveyor line can be used interchangeably. Glass bottles P1, P2, and P3 are used to hold various reagents required for blood testing.

[0107] In the above technical solution: Figure 4 、 5 As shown, the loading device 1 also includes a loading installation panel 19, which includes a loading top plate 191 and a loading protection plate 192 located around the loading top plate 191. Twelve long loading ports 1911 are formed on the loading top plate 191. The front of the loading top plate 191 is also engraved with a label corresponding to each conveyor line. A start button 1921 is provided at the front end of the loading installation panel 19. Loading fixing plates 193 are fixed to the bottom of both sides of the loading protection plate 192; as shown in FIG. Figure 5 As shown, the bottoms of the two loading fixing plates 193 are fixed with side plates 194, and a motor fixing plate 195 is fixed between the two side plates 194. The loading device 1 is fixed to the front frame 61 through the loading fixing plates 193. Reinforcing ribs are provided on the side plates 194, and auxiliary blocks 196 are also fixed to the bottoms of the side plates 194.

[0108] In the above technical solution: Figure 6As shown, each of the twelve conveyor lines includes a loading conveyor belt 11, a loading driving shaft 12, and a loading driven shaft 13. The loading conveyor belt 11 is sleeved on the loading driving shaft 12 and the loading driven shaft 13. Two loading mounting shafts pass through the twelve loading driving shafts 12 and the twelve loading driven shafts 13 respectively. The two ends of the loading mounting shafts are fixed to the loading protection plate 192. Positioning fixtures 16 are fixed to the twelve loading conveyor belts 11. A loading limit plate 14 is also provided directly below the loading port 1911. The portion of the loading conveyor belt 11 that rotates to above the loading driving shaft 12 and the loading driven shaft 13 is located on the loading limit plate 14. A transmission protrusion 121 is provided on the loading driving shaft 12, and a transmission belt 17 is sleeved on the transmission protrusion 121. The transmission belt 17 is driven by a loading motor 18. The loading motor 18 is a stepper motor or a servo motor. The feeding motor 18 is fixed on both sides of the motor fixing plate 195, and the auxiliary block 196 plays an auxiliary protective role for the motor fixing plate 195. If the motor fixing plate 195 falls off from the side plate 194 unexpectedly, the auxiliary block 196 can catch the motor fixing plate 195 to prevent large-scale damage to the feeding device 1. The feeding motor 18 drives the feeding active shaft 12 to rotate through the transmission belt 17. The feeding active shaft 12 cooperates with the feeding driven shaft 13 to drive the feeding conveyor belt 11 and the positioning fixture 16 to move. During the movement of the positioning fixture 16, a part of it is always in a vertical upward state. Only the positioning fixture 16 in a vertical upward state can place the corresponding material. The material passes upward through the feeding port 1911, making it easy to be clamped by the material taking device 2. The positioning fixtures 16 in a vertical upward state on the ten loading conveyor lines, namely the first blood collection tube loading conveyor line, the second blood collection tube loading conveyor line, the measuring cup loading conveyor line, the first reagent tube loading conveyor line, the second reagent tube loading conveyor line, the glass bottle P1 loading conveyor line, the glass bottle P2 loading conveyor line, the glass bottle P3 loading conveyor line, the small suction tip loading conveyor line, and the large suction tip loading conveyor line, have one end of the positioning fixtures 16 in a vertical upward state close to the material taking device 2 as the input and discharge end, and the other end as the input and discharge end; the positioning fixtures 16 in a vertical upward state on the two recovery conveyor lines, namely the first blood collection tube recovery conveyor line and the second blood collection tube recovery conveyor line, have one end of the positioning fixtures 16 in a vertical upward state close to the material taking device 2 as the recovery and discharge end, and the other end as the recovery and discharge end.

[0109] In the above technical solution: Figure 4 、 5As shown, the ten loading and conveying lines, namely the first blood collection tube loading and conveying line, the second blood collection tube loading and conveying line, the measuring cup loading and conveying line, the first reagent tube loading and conveying line, the second reagent tube loading and conveying line, the glass bottle P1 loading and conveying line, the glass bottle P2 loading and conveying line, the glass bottle P3 loading and conveying line, the small suction tip loading and conveying line, and the large suction tip loading and conveying line, also include a first discharge sensor 15. The first discharge sensor 15 corresponds to the position of the positioning fixture 16 at the input and discharge end. The first discharge sensor 15 is a fiber optic sensor. The first discharge sensor 15 is fixed to the side of the loading port 1911. The sensing ends of the ten first discharge sensors 15 are located in the same straight line. The sensing ends of the first discharge sensors 15 are located above the positioning fixture 16 at the input and discharge end. That is, when the corresponding material is placed on the positioning fixture 16, the first discharge sensor 15 can immediately receive the induction and transmit the material retrieving action instruction to the retrieving device 2.

[0110] In the above technical solution: the first blood collection tube recovery conveyor line and the second blood collection tube recovery conveyor line are respectively located on both sides of the loading device 1, and the positioning fixtures 16 on the first blood collection tube recovery conveyor line and the second blood collection tube recovery conveyor line are also provided with sensing holes 161. The first blood collection tube recovery conveyor line and the second blood collection tube recovery conveyor line also include a discharge sensor 110 and a second discharge sensor 111. The discharge sensor 110 corresponds to the position of the positioning fixture 16 at the recovery and discharge end, and the second discharge sensor 111 corresponds to the position of the positioning fixture 16 at the recovery and discharge end. Figure 4 As shown, the material discharge sensor 110 is fixed on the side of the loading port 1911 and is located on the same straight line as the first material discharge sensor 15. Figure 7 As shown, the second discharge sensor 111 is fixed on the inner side of the loading protection plate 192, and the sensing end of the second discharge sensor 111 is located in the sensing hole 161 on the positioning fixture 16 of the recovery discharge end. The second discharge sensor 111 senses whether there is material placed in the positioning fixture 16 through the sensing hole 161. Once the material is sensed, the second discharge sensor 111 will transmit a pause recovery signal to the loading motor 18 of the recovery conveyor line.

[0111] Pressing start button 1921 activates the loading motors 18 on the twelve conveyor lines. The loading motors 18 on ten of the loading conveyor lines rotate the loading drive shafts 12 via the transmission belts 17. The loading drive shafts 12 and the loading driven shafts 13 cooperate to drive the loading conveyor belts 11 and the positioning fixtures 16 toward the reclaimer 2. A person manually places material onto the vertically-upright positioning fixtures 16. When the positioning fixtures 16, with material placed on them, are transferred to the input and discharge ports, the first discharge sensor 15 senses the material and transmits a reclaim action command. Upon receiving this command, the reclaimer 2 grabs the material, completing the loading process.

[0112] After blood sampling is completed, the blood collection tube needs to be recovered. When the discharge sensor 110 senses that there is no material placed on the positioning fixture 16 at the recovery and discharge end, it transmits a discharge action instruction. After receiving this instruction, the material collection device 2 clamps the blood collection tube and places it on the positioning fixture 16 on the first blood collection tube recovery conveyor line and the second blood collection tube recovery conveyor line. The loading motor 18 on the two recovery conveyor lines drives the loading drive shaft 12 to rotate through the transmission belt 17. The loading drive shaft 12 and the loading driven shaft 13 cooperate to drive the loading conveyor belt 11 and the positioning fixture 16 away from the material collection device 2, completing the blood collection tube recovery. When the second discharge sensor 111 senses material in the positioning fixture 16 at the recovery and discharge end through the sensing hole 161, it transmits a pause recovery signal. After receiving this instruction, the loading motor 18 on the recovery conveyor line pauses operation and waits for the material at the recovery and discharge end to be manually removed.

[0113] In the above technical solution: the material taking device 2 is responsible for transferring materials between the feeding device 1 and the batching device 3. Figure 2 、 8 As shown, the reclaiming device 2 includes a reclaiming top plate 26, the bottom of which is provided with a transverse reclaiming mechanism 21, a longitudinal reclaiming mechanism 22, a vertical reclaiming mechanism 23, and a reclaiming rotating mechanism 24 in order from top to bottom. Vertical columns 25 are fixed on both sides of the bottom of the reclaiming top plate 26, and the vertical columns 25 are fixed to the front bracket 6.

[0114] In the above technical solution: Figure 8 、 12As shown, the transverse feeding mechanism 21 includes a transverse feeding guide block 211 fixed below the feeding top plate 26. A transverse feeding slider 212 is provided at the bottom of the transverse feeding guide block 211. The transverse feeding slider 212 is driven by a first transverse drive mechanism and can move along the transverse feeding guide block 211. The first transverse drive mechanism is a first composite transmission mechanism, which includes a third screw and a transverse feeding motor 213. The function of the screw is to convert rotational motion into linear motion. A fifth cavity is formed within the transverse feeding guide block 211. The third screw is located within the fifth cavity. The third screw includes a third screw and a third nut that engages with the third screw thread. A transverse feeding transmission block 214 is mounted on the transverse feeding guide block 211. The transverse feeding motor 213 is mounted on the transverse feeding transmission block 214 or on the frame of the blood testing machine. In this embodiment, the transverse feed motor 213 is mounted on the transverse feed transmission block 214, which reduces the vibration effects of other components of the blood testing machine on the transverse feed motor 213 during operation. This also allows the transverse feed motor 213 to be combined with other components of the transverse feed mechanism 21 to form an independent module, making installation and disassembly easier. The transverse feed transmission block 214 allows the transverse feed motor 213 to be arranged parallel to the transverse feed guide block 211, thereby reducing the lateral dimensions and effectively utilizing the free vertical space, thereby reducing the overall footprint of the machine. A fifth and sixth transmission shafts are provided within the transverse feed transmission block 214. The fifth transmission shaft is fixed to the rotating shaft within the transverse feed motor 213, and the sixth transmission shaft is fixed to the third screw within the transverse feed guide block 211. Third synchronous pulleys are provided on both the fifth and sixth transmission shafts, and a third belt is sleeved between the two third synchronous pulleys. A fifth sensing rod is fixed to the transverse feed slide 212. A fifth sliding hole is formed in the transverse feed guide block 211, which communicates with the fifth cavity. The fifth sensing rod passes through the fifth sliding hole and is connected to the third nut. A first limit sensor, a first origin sensor, and a second limit sensor are mounted on the transverse feed guide block 211 to sense the fifth sensing rod. The first and second limit sensors are respectively fixed to opposite ends of a side of the transverse feed guide block 211, with the first origin sensor located between the first and second limit sensors. When the transverse feed motor 213 is activated, its shaft rotates the third screw via the fifth drive shaft, the third belt, and the sixth drive shaft. The third screw drives the third nut to move axially along the third screw, which in turn drives the transverse feed slide 212 and the fifth sensing rod along the transverse feed guide block 211. The transverse feed motor 213 first drives the fifth sensing rod to align with the first origin sensor. When the first origin sensor senses the fifth sensing rod, the transverse feed motor 213 resets to its origin.Then the horizontal material picking motor 213 continues to drive the horizontal material picking slider 212 and the fifth sensing rod to move; in the above process, when the first limit sensor senses the fifth sensing rod, the horizontal material picking motor 213 stops moving; when the second limit sensor senses the fifth sensing rod, the horizontal material picking motor 213 stops moving, so the first limit sensor and the second limit sensor play a limiting role in the movement of the horizontal material picking slider 212.

[0115] In the above technical solution: Figure 8 、 12As shown, the longitudinal feed mechanism 22 includes a longitudinal feed guide block 221 secured to the bottom of the transverse feed slider 212 via a longitudinal feed connecting plate 225. A longitudinal feed slider 223 is disposed at the bottom of the longitudinal feed guide block 221. The longitudinal feed slider 223 is driven by a first longitudinal drive mechanism and can move along the longitudinal feed guide block 221. The first longitudinal drive mechanism is a second composite transmission mechanism comprising a fourth screw and a longitudinal feed motor 222. A sixth cavity is defined within the longitudinal feed guide block 221, within which a fourth screw is located. The fourth screw comprises a fourth screw and a fourth nut threadedly engaged with the fourth screw. A longitudinal feed transmission block 224 is mounted on the longitudinal feed guide block 221, and the longitudinal feed motor 222 is mounted on the longitudinal feed transmission block 224 or on the frame of the blood testing machine. In this embodiment, the longitudinal feed motor 222 is mounted on the longitudinal feed transmission block 224, which reduces the vibrations from other components of the blood testing machine while the longitudinal feed motor 222 is in operation. This also allows the longitudinal feed motor 222 to be combined with other components of the longitudinal feed mechanism 22 to form an independent module, making installation and disassembly easier. The longitudinal feed transmission block 224 allows the longitudinal feed motor 222 to be arranged parallel to the longitudinal feed guide block 221, thereby reducing the lateral dimensions and effectively utilizing the free vertical space, thereby reducing the overall footprint of the machine. A seventh and eighth transmission shafts are disposed within the longitudinal feed transmission block 224. The seventh transmission shaft is fixed to the rotating shaft within the longitudinal feed motor 222, and the eighth transmission shaft is fixed to the fourth screw within the longitudinal feed guide block 221. Fourth synchronous pulleys are provided on both the seventh and eighth transmission shafts, and a fourth belt is sleeved between the two fourth synchronous pulleys. A sixth sensing rod is fixed to the longitudinal feeder slider 223. A sixth sliding hole is formed in the longitudinal feeder guide block 221, which is connected to the sixth cavity. The sixth sensing rod passes through the sixth sliding hole and is connected to the fourth nut. A third limit sensor, a second origin sensor, and a fourth limit sensor for sensing the sixth sensing rod are mounted on the longitudinal feeder guide block 221. The third and fourth limit sensors are respectively fixed to opposite ends of a side surface of the longitudinal feeder guide block 221, with the second origin sensor located between the third and fourth limit sensors. The longitudinal feeder motor 222 is activated. The shaft of the longitudinal feeder motor 222 drives the fourth screw to rotate via the seventh transmission shaft, the fourth belt, and the eighth transmission shaft. The fourth screw drives the fourth nut to move axially along the fourth screw. The fourth nut drives the longitudinal feeder slider 223 and the sixth sensing rod to move along the longitudinal feeder guide block 221. The longitudinal material-retrieving motor 222 first drives the sixth sensing rod to move to cooperate with the second origin sensor. When the second origin sensor senses the sixth sensing rod, the longitudinal material-retrieving motor 222 is reset to the origin.Then the longitudinal material picking motor 222 continues to drive the longitudinal material picking slider 223 and the sixth sensing rod to move; in the above process, when the third limit sensor senses the sixth sensing rod, the longitudinal material picking motor 222 stops moving; when the fourth limit sensor senses the sixth sensing rod, the longitudinal material picking motor 222 stops moving, so the third limit sensor and the fourth limit sensor play a limiting role in the movement of the longitudinal material picking slider 223.

[0116] In the above technical solution: Figure 8 、 12As shown, the upper and lower feeding mechanism 23 includes an upper and lower feeding guide block 231 secured to the bottom of the longitudinal feeding slider 223 via a T-shaped upper and lower feeding connecting plate 28. An L-shaped upper and lower feeding slider 233 is provided on the side of the upper and lower feeding guide block 231. The upper and lower feeding slider 233 is driven by a first upper and lower driving mechanism and can move along the upper and lower feeding guide block 231. The first upper and lower driving mechanism is a third composite transmission mechanism comprising a fifth screw and an upper and lower feeding motor 232. The upper and lower feeding guide block 231 defines a seventh cavity, within which the fifth screw is located. The fifth screw comprises a fifth screw and a fifth nut threadedly engaged with the fifth screw. An upper and lower feeding transmission block 237 is mounted on the upper and lower feeding guide block 231, and the upper and lower feeding motor 232 is mounted on the upper and lower feeding transmission block 237 or on the frame of the blood testing machine. In this embodiment, the upper and lower feeding motors 232 are mounted on the upper and lower feeding transmission blocks 237, which reduces the vibrations from other components of the blood testing machine when the upper and lower feeding motors 232 are in operation. This also allows the upper and lower feeding motors 232 to be combined with other components of the upper and lower feeding mechanism 23 to form an independent module, making installation and disassembly easier. The upper and lower feeding transmission blocks 237 allow the upper and lower feeding motors 232 to be arranged parallel to the upper and lower feeding guide blocks 231, thereby reducing the longitudinal dimensions and effectively utilizing the free horizontal space, thereby reducing the overall footprint of the machine. The upper and lower feeding transmission blocks 237 contain a ninth and tenth transmission shaft. The ninth transmission shaft is fixed to the rotating shaft within the upper and lower feeding motor 232, and the tenth transmission shaft is fixed to the fifth screw within the upper and lower feeding guide blocks 231. Both the ninth and tenth transmission shafts are provided with fifth synchronous pulleys, with a fifth belt positioned between the two fifth synchronous pulleys. A seventh sensing rod is fixed to the transverse portion of the L-shaped upper and lower reclaiming slider 233. A seventh sliding hole is formed in the upper and lower reclaiming guide block 231, which communicates with the seventh cavity. The seventh sensing rod passes through the seventh sliding hole and is connected to the fifth nut. The upper and lower reclaiming guide block 231 is mounted with a fifth limit sensor 234, a third origin sensor 235, and a sixth limit sensor 236 for sensing the seventh sensing rod. The fifth and sixth limit sensors 234, 236 are respectively fixed to opposite ends of a side of the upper and lower reclaiming guide block 231, with the third origin sensor 235 located between the fifth and sixth limit sensors 234, 236. When the upper and lower reclaiming motor 232 is activated, its shaft drives the fifth screw to rotate via the ninth drive shaft, the fifth belt, and the tenth drive shaft. The fifth screw drives the fifth nut to move axially along the fifth screw, which in turn drives the upper and lower reclaiming sliders 233 and the seventh sensing rod to move along the upper and lower reclaiming guide block 231. The upper and lower material taking motor 232 first drives the seventh sensing rod to move to cooperate with the third origin sensor 235. When the third origin sensor 235 senses the seventh sensing rod, the upper and lower material taking motor 232 is reset to the origin.Then the upper and lower material picking motors 232 continue to drive the upper and lower material picking sliders 233 and the seventh sensing rod to move; in the above process, when the fifth limit sensor 234 senses the seventh sensing rod, the upper and lower material picking motors 232 stop moving; when the sixth limit sensor 236 senses the seventh sensing rod, the upper and lower material picking motors 232 stop moving, so the fifth limit sensor 234 and the sixth limit sensor 236 play a limiting role in the movement of the upper and lower material picking sliders 233.

[0117] In the above technical solution: Figure 8 、 12 As shown, the material retrieving rotation mechanism 24 includes a retrieving rotation transmission block 247 fixed to the bottom of the upper and lower retrieving sliders 233 via a rotating connecting plate 243. The retrieving rotation transmission block 247 is equipped with a retrieving rotation motor 241. A first gear and a second gear are horizontally arranged in the retrieving rotation transmission block 247, which are meshed with each other. The first gear is fixed to the rotating shaft of the retrieving rotation motor 241, and the second gear is fixed to the retrieving rotation sensing rod. The bottom of the retrieving rotation sensing rod passes through the retrieving rotation transmission block 247 and is fixed to the retrieving fixing plate 242. The bottom of the retrieving fixing plate 242 is fixed to the first electric clamp 10 responsible for retrieving. The retrieving rotation motor 241 drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the first electric clamp 10 to rotate via the retrieving rotation sensing rod.

[0118] In the above technical solution, a first analog sensor is provided on the first electric gripper 10. When the first electric gripper 10 grips a material, the first analog sensor can determine the size of the material based on the degree of gripping by the first electric gripper 10, thereby determining the type of material being gripped. If the first analog sensor determines that the material gripped by the first electric gripper 10 is different from the material that the first electric gripper 10 is programmed to grip, it indicates that the incorrect material has been manually placed on the loading device 1. The program automatically issues an alarm, notifying the operator to address the issue. The analog sensor in the present invention is prior art.

[0119] In the above technical solution: Figure 12 As shown, a material picking origin sensor 245 is fixed to the back of the material picking rotary motor 241, and a material picking origin induction sheet 246 is correspondingly fixed to the material picking fixed plate 242. When the material picking rotary motor 241 drives the material picking fixed plate 242 and the material picking origin induction sheet 246 to rotate, when the material picking origin sensor 245 senses the material picking origin induction sheet 246, the material picking rotary motor 241 stops moving and the origin is successfully found. The material picking origin induction sheet 246 is used in conjunction with the material picking origin sensor 245 to ensure that the material picking rotary motor 241 can return to the origin after each rotation. Material picking fingers 244 are installed on the clamping piston rods on both sides of the first electric clamp 10, as shown in FIG. Figure 9As shown, the two gripping fingers 244 are each formed with a gripping finger groove 2441 on the opposite side of their heads. Curved gripping notches 2442 are formed on the upper and lower walls of the gripping finger grooves 2441. When a blood collection tube or reagent tube is to be gripped, the tube or tube is gripped by the gripping notches 2442. When a measuring cup is to be gripped, the lower gripping notch 2442 grips the outer wall of the measuring cup, with the head of the measuring cup positioned within the gripping finger grooves 2441.

Figure 8 and Figure 12 In order to prevent the retrieving drag chain box 27 from blocking other components, the retrieving drag chain box 27 is not connected to the second drag chain fixing plate 272. The wires in the retrieving device 2 are all located in the retrieving drag chain box 27, which is used to protect and constrain the wires to facilitate their movement.

The batching device 3 is fixed to the rear mounting hole 64 through the batching plate 301 at the bottom. Figure 1 As shown, a safety shield 306 is fixed to the batching plate 301. The front of the shield 306 has a material hole for allowing material from the loading device 1 to pass through. The back of the shield 306 has a material transfer hole 3061 that cooperates with the material transfer device 4. A control button 3062 and a discharge door 3063 are provided on one side of the shield 306. The batching plate 301 also has a front waste hole, on which a front waste hopper 302 is mounted. A front waste channel 303 is connected below the front waste hopper 302. A front waste slide 304 is located below the front waste channel 303 and is fixed to the bottom of the batching plate 301 via a front connector 305. The material removal device 2 picks up waste material and places it into the front waste hopper 302. The waste passes through the front waste channel 303 and the front waste slide 304 and enters the trash can.

[0122] In the above technical solution: the cap screwing mechanism 31 is responsible for opening and closing the reagent tube, and the tube cap and the tube body of the reagent tube are threaded. Figure 14As shown, the capping mechanism 31 includes a capping back plate 3101, and capping side plates 3102 are fixed on both sides of the back of the capping back plate 3101. The bottom of the capping side plates 3102 is fixed on the ingredient plate 301. The ingredient plate 301 is provided with a capping moving hole. The bottom of the capping back plate 3101 passes through the capping moving hole, and the top of the capping back plate 3101 is provided with an ingredient rotating mechanism 39.

[0123] In the above technical solution: Figure 15 、 16As shown, the batching rotation mechanism 39 includes a batching rotation motor 391, a front synchronous shaft 392, a rear synchronous shaft 393, and a motor top plate 394. A mounting hole 3941 is formed at one end of the motor top plate 394, and mounting steps 3942 are formed on both sides of the mounting hole 3941. A plurality of bolt holes 3943 are formed on the mounting steps 3942. In this embodiment, six bolt holes 3943 are provided on each side of the mounting steps 3942. A motor connecting plate 395 is provided in the mounting hole 3941. The batching rotation motor 391 is fixed to the bottom of the motor connecting plate 395, and the rotating shaft of the batching rotation motor 391 passes through the motor connecting plate 395 and is connected to the rear synchronous shaft 393. The motor connecting plate 395 has mounting portions 3951 formed on both sides, each with a movable strip-shaped hole 3952 formed therein. The mounting portions 3951 are located on the mounting step 3942. Bolts pass through the movable strip-shaped hole 3952 and the bolt hole 3943 and engage with the fixing nut to mount the motor connecting plate 395 on the motor top plate 394. After installation, there is still room for the bolts to move within the movable strip-shaped hole 3952. When the motor connecting plate 395 needs to be moved, it can be pushed without completely removing the bolts before moving. The bolt hole 3943 in which the bolt is fixed determines the position and movement space of the motor connecting plate 395. A motor top block 396 is also fixed to the side of the mounting hole 3941 near the middle of the motor top plate 394 to prevent the motor connecting plate 395 from moving excessively. A rotating bearing seat 397 is fixed to the other end of the motor top plate 394. A rotating shaft 398 is mounted within the rotating bearing seat 397. The rotating shaft 398 is fixed to the front synchronous shaft 392. A timing belt 399 is sleeved between the front synchronous shaft 392 and the rear synchronous shaft 393. When the timing belt 399 needs to be adjusted, the motor connecting plate 395 is moved. A batching origin sensor 3910 is fixed to the middle of the motor top plate 394 via a Z-shaped fixing plate. The top of the rotating shaft 398 passes through the front synchronous shaft 392 and is fixed with a batching origin sensor plate 3911. As the batching rotation motor 391 drives the rear synchronous shaft 393, the front synchronous shaft 392, and the batching origin sensor 3911 to rotate, when the batching origin sensor 3910 senses the batching origin sensor 3911, the batching rotation motor 391 returns to its origin. The batching origin sensor 3911 and the batching origin sensor 3910 work together to ensure that the batching rotation motor 391 returns to its origin regardless of whether the lid is opened or closed. An electrical slip ring 3912 is also provided on the top of the rotating shaft 398. A support plate 3913 is supported on the rotating bearing seat 397 via two support rods. The electrical slip ring 3912 is located on the support plate 3913. The wires on the batching rotation mechanism 39 are all connected to the electrical slip rings. During rotation, the electrical slip rings remain stationary, so that a certain section of the wire remains stationary, preventing the wire from becoming tangled. A rotating safety cover 3914 is also installed on the motor top plate 394 , and the rotating safety cover 3914 is used to protect the various components on the motor top plate 394 .

[0124] In the above technical solution: Figure 15 As shown, the bottom of the rotating shaft 398 passes through the motor top plate 394 and is connected to the second electric gripper 100 for clamping the reagent tube cap. The gripper piston rods on both sides of the second electric gripper 100 are both equipped with reagent tube cap clamping fingers 313. The bottom of each reagent tube cap clamping finger 313 is formed with a semi-cylindrical clamping portion 3131, and the opposite side of the two clamping portions 3131 is formed with an arc-shaped tube cap groove 31311. The top of the tube cap groove 31311 is also formed with a tube cap sensing groove 31312. The groove wall of the tube cap groove 31311 is also formed with a plurality of vertically arranged and evenly arranged tube cap strip grooves 31313. The bottom of the tube cap strip groove 31313 is arc-shaped. The tube cap strip groove 31313 cooperates with the reagent tube cap, increasing friction and facilitating the screwing of the cap.

[0125] In the above technical solution: Figure 14 、 15 As shown, a height adjustment device 319 is also provided on the screw cap back plate 3101, to which a third electric clamp 200 for clamping the reagent tube body is connected. Reagent tube body clamping fingers 315 are installed on the clamping piston rods on both sides of the third electric clamp 200. The reagent tube body clamping fingers 315 are located directly below the reagent tube cap clamping fingers 313. The two reagent tube body clamping fingers 315 are formed with a fixing groove 3151 on the side opposite to the head of the two reagent tube body clamping fingers 315. An elastomer is provided in the fixing groove 3151. When the reagent tube body clamping fingers 315 clamp the reagent tube body, the elastomer squeezes the reagent tube body to make the clamping more secure. Since the elastomer is elastic, the reagent tube body will not be excessively squeezed and cause the tube body to break. In this embodiment, the elastomer is a polyurethane elastomer (also known as a polyurethane PU elastomer), which has the advantages of good strength and small compression deformation.

[0126] In the above technical solution: Figure 14 、 15As shown, the height adjustment device 319 includes a guide rail 3114 fixed to the front of the cover screwing back plate 3101, a guide slider 3115 is provided on the guide rail 3114, a sliding connecting plate 3116 is fixed to the guide slider 3115, and the third electric clamp 200 is fixed to the sliding connecting plate 3116. The height adjustment device 319 also includes a reagent tube guide block 3192 fixed to the back of the cover screwing back plate 3101. The side of the reagent tube guide block 3192 is provided with an L-shaped height adjustment slider 3193. The height adjustment slider 3193 is driven by the first drive mechanism and can move along the reagent tube guide block 3192. The first drive mechanism is a fourth composite transmission mechanism, which includes a sixth screw and a reagent tube moving motor 3191. The function of the screw is to convert rotational motion into linear motion. The reagent tube guide block 3192 is formed with an eighth cavity. The sixth screw is located in the eighth cavity. The sixth screw includes a sixth screw and a sixth nut that is threadedly engaged with the sixth screw. A reagent tube transmission block 3194 is mounted on the reagent tube guide block 3192, and the reagent tube moving motor 3191 is mounted on the reagent tube transmission block 3194 or on the frame of the blood testing machine. In this embodiment, the reagent tube moving motor 3191 is mounted on the reagent tube transmission block 3194, which reduces the vibration of the reagent tube moving motor 3191 from other components of the blood testing machine during operation. At the same time, the reagent tube moving motor 3191 and the other components of the height adjustment device 319 are combined to form an independent module, which facilitates installation and removal. The reagent tube transmission block 3194 allows the reagent tube moving motor 3191 to be arranged parallel to the reagent tube guide block 3192, thereby reducing the longitudinal dimension, effectively utilizing the free space in the horizontal direction, and thus reducing the space occupied by the entire machine. The reagent tube transmission block 3194 is provided with an eleventh transmission shaft and a twelfth transmission shaft. The eleventh transmission shaft is fixed to the rotating shaft in the reagent tube moving motor 3191, and the twelfth transmission shaft is fixed to the sixth screw in the reagent tube guide block 3192. Sixth synchronous pulleys are provided on both the eleventh transmission shaft and the twelfth transmission shaft, and a sixth belt is sleeved between the two sixth synchronous pulleys. An eighth sensing rod is fixed to the height adjustment slider 3193. An eighth sliding hole is formed in the reagent tube guide block 3192, and the eighth sliding hole is connected to the eighth cavity. The eighth sensing rod passes through the eighth sliding hole and is connected to the sixth nut. The reagent tube guide block 3192 is equipped with a seventh limit sensor, a fourth origin sensor, and an eighth limit sensor for sensing the eighth sensing rod. The seventh limit sensor and the eighth limit sensor are respectively fixed at both ends of one side of the reagent tube guide block 3192. The fourth origin sensor is located between the seventh limit sensor and the eighth limit sensor and is installed on the other side of the reagent tube guide block 3192.The reagent tube moving motor 3191 is activated. The rotating shaft of the reagent tube moving motor 3191 rotates the sixth screw via the eleventh drive shaft, the sixth belt, and the twelfth drive shaft. The sixth screw drives the sixth nut to move axially along the sixth screw, which in turn drives the height adjustment slider 3193 and the eighth sensing rod to move along the reagent tube guide block 3192. The reagent tube moving motor 3191 first drives the eighth sensing rod to align with the fourth origin sensor. When the fourth origin sensor senses the eighth sensing rod, the reagent tube moving motor 3191 returns to its origin. The reagent tube moving motor 3191 then continues to drive the height adjustment slider 3193 and the eighth sensing rod. During this process, when the seventh limit sensor senses the eighth sensing rod, the reagent tube moving motor 3191 stops. When the eighth limit sensor senses the eighth sensing rod, the reagent tube moving motor 3191 also stops. Therefore, the seventh and eighth limit sensors limit the movement of the height adjustment slider 3193.

[0127] In the above technical solution, a fixing sleeve 3120 is mounted at the bottom of the horizontal portion of the L-shaped height adjustment slider 3193. A compression spring is disposed within the fixing sleeve 3120. One end of the compression spring is fixed within the fixing sleeve 3120, and the other end is connected to an adjustment column 3121, which can move up and down within the fixing sleeve 3120. The arrangement of the adjustment column 3121 and the compression spring acts as a buffer during the height adjustment process. When the height adjustment slider 3193 moves downward, the compression spring is first compressed, and the force is then transmitted to the third electric gripper 200 through the compression spring and the adjustment column 3121, thereby improving the safety and stability of opening and closing the reagent tube cover. A U-shaped connecting plate 3117 is fixed to the bottom of the adjusting column 3121, and two vertically arranged limit grooves 31011 are formed on the bottom of the screw cover back plate 3101. The opening of the U-shaped connecting plate 3117 passes through the limit groove 31011 and is fixed to the bottom of the sliding connecting plate 3116, thereby realizing that the height adjustment device 319 drives the reagent tube body in the reagent tube body clamping finger 315 to move up and down.

[0128] In the above technical solution: two tension springs 3113 are also provided between the sliding connecting plate 3116 and the screw cover back plate 3101, two lower tension spring rods are fixed on the back of the sliding connecting plate 3116, and two upper tension spring rods are fixed on the screw cover back plate 3101, and the two ends of the tension spring 3113 are respectively connected to the upper and lower tension spring rods.

[0129] In the above technical solution: a reagent tube cover sensor 3118 and a reagent tube body sensor 3119 are also fixed to the front of the screw cap back plate 3101, and the reagent tube cover sensor 3118 and the reagent tube body sensor 3119 are both optical fiber sensors.

[0130] When uncapping a reagent tube, the dispensing device 2 transfers the tube between the two reagent tube cap gripping fingers 313. The second electric gripper 100 drives the reagent tube cap gripping fingers 313 to grip the tube cap. The height adjustment device 319 drives the reagent tube body gripping fingers 315 upward, and the third electric gripper 200 drives the reagent tube body gripping fingers 315 to grip the tube body. The batching rotation motor 391 is then activated, and the rear synchronous shaft 393 rotates the front synchronous shaft 392 via the synchronous belt 399, thereby also rotating the reagent tube cap within the reagent tube cap gripping fingers 313. During the uncapping process, the tube cap gradually separates from the tube body. However, since the tube cap does not move, the uncapping process exerts a downward force on the tube body, driving it downward. This force also stretches the tension spring 3113, which simultaneously generates a counterforce to its restorative state, ensuring that the head of the tube body and the tube cap remain in contact with each other during the uncapping process, preventing them from interlocking. The operation of the batching rotary motor 391 stops until the tube cover sensing slot 31312 is aligned with the reagent tube cover sensor 3118. If the reagent tube is successfully opened, the reagent tube cover will be left in the reagent tube cover clamp finger 313. The reagent tube cover sensor 3118 senses whether the reagent tube cover is clamped in the reagent tube cover clamp finger 313 through the tube cover sensing slot 31312, thereby verifying whether the reagent tube opening and closing is successful. When the batching rotary motor 391 stops, the reagent tube is just opened and the reagent tube body is separated from the reagent tube cover. After the reagent tube is opened, the height adjustment device 319 drives the reagent tube body in the reagent tube body clamp finger 315 to move downward. When the reagent tube body sensor 3119 senses the reagent tube, it transmits the clamping instruction to the material picking device 2, and the reagent tube body waits to be taken away by the material picking device 2.

[0131] When the reagent tube is closed, the material removal device 2 drives the reagent tube body to move between the two reagent tube body clamping fingers 315, and the third electric clamp 200 drives the reagent tube body clamping fingers 315 to clamp the reagent tube body. The height adjustment device 319 drives the reagent tube body to rise until the top of the tube body contacts the bottom of the reagent tube cover. At this time, the tension spring 3113 has not yet fully recovered, and the restoring force of the tension spring 3113 exerts an upward force on the reagent tube body. The batching rotation motor 391 is then started, and the rear synchronous shaft 393 drives the front synchronous shaft 392 to rotate via the synchronous belt 399, thereby also driving the reagent tube cover within the reagent tube cover clamping fingers 313 to rotate. When the threaded connection between the reagent tube cover and the reagent tube body is aligned, the reagent tube body is screwed into the reagent tube cover. At the same time, the reagent tube body is driven upward by the restoring force of the tension spring 3113 so that it is in close contact with the reagent tube opening, completing the reagent tube closing. After the reagent tube is covered, the third electric clamp 200 drives the reagent tube body clamping fingers 315 to move to both sides to loosen the reagent tube body, and the height adjustment device 319 drives the reagent tube body clamping fingers 315 to descend; when the reagent tube body sensor 3119 senses the reagent tube, it transmits the clamping instruction to the material picking device 2, and the reagent tube waits to be taken away and recycled by the material picking device 2.

[0132] In the above technical solution: Figure 17 As shown, the flip mechanism 32 is fixed to the ingredient plate 301 via a fixed base 328. A support plate 325 is fixed to the fixed base 328. A flip reinforcement rib 326 is also fixed between the support plate 325 and the fixed base 328. A flip hole is formed on the upper portion of the support plate 325, and a finger shaft is provided in the flip hole. One end of the finger shaft is connected to the fourth electric clamp 300 responsible for clamping the blood collection tube or reagent tube that needs to be flipped. The clamp piston rods on both sides of the fourth electric clamp 300 are both equipped with flip fingers 322. In this embodiment, the other end of the finger shaft is indirectly connected to the rotating shaft on the flip motor 323 via a connecting shaft; of course, if a longer finger shaft is selected, the other end of the finger shaft can also be directly connected to the rotating shaft on the flip motor 323. A tilting bearing seat 327 is also secured to the support plate 325. This seat comprises two bearing plates and a hollow column positioned between them. The finger-clamping shaft and connecting shaft are located within the hollow column. The two bearing plates are secured to the tilting motor 323 and the support plate 325, respectively. This embodiment provides a mounting location for the tilting motor 323 by providing a more independent structure for the tilting mechanism, facilitating its removal and installation. More importantly, it reduces the vibrations from other components of the blood testing machine while the tilting motor 323 is in operation. Alternatively, the tilting motor 323 can be mounted in a corresponding position on the front frame 6 of the blood testing machine.

[0133] In the above technical solution: Figure 17As shown, the two flip clamping fingers 322 are formed with an arc-shaped small clamping finger notch 3221 and a large clamping finger notch 3222 on the opposite side of the head. The flip clamping fingers 322 are responsible for clamping the blood collection tube and the reagent tube. Usually, since the blood collection tube is larger than the reagent tube, in this embodiment, the small clamping finger notch 3221 is used to clamp the reagent tube, and the large clamping finger notch 3222 is used to clamp the blood collection tube.

[0134] In the above technical solution: Figure 17 As shown, a flip sensor 329 is fixed to the support plate 325, and a flip sensing plate 3210 is correspondingly fixed to the bottom of the fourth electric gripper 300. When the flip motor 323 drives the fourth electric gripper 300 and the flip sensing plate 3210 to rotate, when the flip sensor 329 senses the flip sensing plate 3210, the flip motor 323 returns to its origin. The flip sensor 329 and the flip sensing plate 3210 work together to ensure that the flip motor 323 returns to its origin after each flip.

[0135] When flipping is required, the material picking device 2 moves the blood collection tube or reagent tube to between the two flipping fingers 322, and the fourth electric clamp 300 drives the flipping fingers 322 to move from both sides to the middle and clamp the blood collection tube or reagent tube, and then the flipping motor 323 drives the blood collection tube or reagent tube clamped by the flipping fingers 322 to flip.

[0136] In the above technical solution: Figure 18As shown, the resting mechanism 33 includes a resting fixture 331 and several resting sensors 332. The resting fixture 331 is provided with several resting slots 3311 for reagent tubes and several resting slots 3312 for blood collection tubes. Because reagent tubes are smaller than blood collection tubes, the bottoms of the reagent tube resting slots 3311 are higher than the bottoms of the blood collection tube resting slots 3312. A resting sensor 332 is provided for each reagent tube resting slot 3311 and each blood collection tube resting slot 3312. The sensing end of the resting sensor 332 corresponding to the reagent tube resting slot 3311 is located above the reagent tube resting slot 3311, while the sensing end of the resting sensor 332 corresponding to the blood collection tube resting slot 3312 is located above the blood collection tube resting slot 3312. The stationary fixture 331 also has a fixing slot 3313, with a fixing hole 3314 formed at the bottom thereof. Screws pass through the fixing holes 3314 to secure the stationary fixture 331 to the ingredient plate 301. In this embodiment, there are three reagent tube resting slots 3311, evenly distributed on the right half of the stationary fixture 331; there are three blood collection tube resting slots 3312, evenly distributed on the left half of the stationary fixture 331. The resting sensor 332 is used to sense whether a reagent tube is placed in the reagent tube resting slot 3311 or a blood collection tube is placed in the blood collection tube resting slot 3312. Only when the resting sensor 332 detects no reagent tube or blood collection tube will the dispensing device 2 place the reagent tube or blood collection tube into the corresponding reagent tube or blood collection tube resting slot. After the blood collection tube or the reagent tube is turned over by the turning mechanism 32 , the material taking device 2 moves the blood collection tube or the reagent tube to the stationary mechanism 33 , and the blood collection tube and the reagent tube are respectively stationary.

[0137] In the above technical solution: Figure 13 、 19 As shown in Figures 20 and 20, the cap removal and code scanning mechanism 34 is responsible for scanning the barcode of the blood collection tube and opening and closing the cap of the blood collection tube. The cap removal and code scanning mechanism 34 includes a cap removal back plate 348 and cap removal side plates 3418 located on both sides of the cap removal back plate 348. The bottom of the cap removal side plates 3418 is fixed to the ingredient plate 301. The ingredient plate 301 is provided with a cap removal movement hole. The bottom of the cap removal back plate 348 passes through the cap removal movement hole. The top of the cap removal back plate 348 is provided with an ingredient rotation mechanism 39. The bottom of the rotating shaft 398 of the ingredient rotation mechanism 39 is connected to the fifth electric clamp 400 for clamping the blood collection tube cap. The clamp piston rods on both sides of the fifth electric clamp 400 are both equipped with blood collection tube cap clamping fingers 343. Figure 23As shown, the lower portion of each opposing side of the two blood collection tube cap clamping fingers 343 is formed with an arc-shaped positioning cavity 3431. The bottom of the positioning cavity 3431 is formed with an overall arc-shaped cover removal step 3432. When the blood collection tube cap clamping fingers 343 clamp the blood collection tube cap, the cover removal step 3432 is located below the blood collection tube cap and closely adheres to the blood collection tube body. The positioning cavity 3431 is also formed with a circular hole 3433. The top of the positioning cavity 3431 is also formed with an arc-shaped cover removal movable cavity 3434, which is used to accommodate the top of the blood collection tube cap. In order to more clearly illustrate the structure of each component, Figure 13 and Figure 19 The rotating safety cover 3914 on the ingredient rotating mechanism 39 on the top of the cover back plate 348 is omitted. Figure 20 The rotating safety cover 3914 on the ingredient rotating mechanism 39 on the top of the lid-pulling back plate 348 and the lid-pulling side plate 3418 on one side are omitted.

[0138] In the above technical solution: a barcode scanner 3415 is fixed on the cover-pulling back plate 348, and the height of the barcode scanner 3415 is consistent with the height of the barcode on the blood collection tube when it is clamped by the tube cover clamping fingers 343. The ingredient rotating mechanism 39 on the top of the cover-pulling back plate 348 drives the blood collection tube to rotate, and the barcode scanner 3415 reads the barcode information on the blood collection tube to complete the scanning.

[0139] In the above technical solution, a pipetting device 342 is also fixed to one side of the cover removal back plate 348 via a pipetting connection plate 3416. The pipetting device 342 includes a pipetting guide block 3422 and a pipette 349. A pipetting rail 3423 is fixed to the side of the pipetting guide block 3422. A pipetting slider 3424 is mounted on the pipetting rail 3423, and the pipette 349 is fixed to the pipetting slider 3424. The pipetting slider 3424 is driven by a sixth drive mechanism and can move along the pipetting rail 3423. The sixth drive mechanism is a first screw transmission mechanism, which includes a seventh screw and a pipetting motor 3421. The screw's function is to convert rotational motion into linear motion. The seventh screw includes a seventh screw and a seventh nut threadedly engaged with the seventh screw. The seventh screw is connected to the rotating shaft of the pipetting motor 3421 via a coupling. A ninth sensing rod is fixed to the pipetting slider 3424, and the ninth sensing rod is connected to the seventh nut. A ninth cavity for mounting a first screw transmission mechanism is formed in the pipetting guide block 3422, wherein the seventh screw is located in the ninth cavity. The pipetting motor 3421 is mounted on the pipetting guide block 3422 or on the frame of the blood testing machine. In this embodiment, the pipetting motor 3421 is mounted on the pipetting guide block 3422, which reduces the vibration of the other components of the blood testing machine when the pipetting motor 3421 is in operation; at the same time, the pipetting motor 3421 is combined with other components of the pipetting device 342 to form an independent module, which is convenient for installation and disassembly. A ninth sliding hole is formed on the pipetting guide block 3422, which is connected to the ninth cavity. The ninth sensing rod passes through the ninth sliding hole and is connected to the seventh nut. The first screw transmission mechanism is driven by the pipetting motor 3421, which has low noise. The seventh screw cooperates with the pipetting motor 3421 to achieve rigid transmission, and the transmission is timely and rapid.

[0140] In the above technical solution, the pipette 349 includes a tip detachment guide block 3495 fixed to the pipetting slider 3424. A tip fixing tube 3492 is fixed to the bottom of the tip detachment guide block 3495. The bottom of the tip fixing tube 3492 is formed with a fixed inclined surface 34921 that cooperates with the tip. A tip detachment tube 3493 is sleeved on the tip fixing tube 3492, and the fixed inclined surface 34921 is exposed at the bottom of the tip detachment tube 3493. A transmission rod 3494 is also provided at the bottom of the tip detachment guide block 3495. Figure 21 As shown, a buffer spring 3496 is sleeved on the transmission rod 3494, and an upper limit block 34941 and a lower limit block 34942 are formed at the bottom of the transmission rod 3494, and a slot is formed between the upper and lower limit blocks 34941 and 34942. Figure 21 、 22As shown, an extension block 3497 is fixed to the top of the tip detachment tube 3493. The extension block 3497 includes a connecting portion 34971 fixed to the tip detachment tube 3493, an overall C-shaped block portion 34972, and a handle portion 34973. The block portion 34972 is also provided with a bending groove 34974. The bottom of the transmission rod 3494 extends out of the tip detachment guide block 3495, and the block portion 34972 engages the groove, securing the transmission rod 3494 to the tip detachment tube 3493. To remove the tip detachment tube 3493, the handle portion 34973 is gripped and applied to disengage the block portion 34972 from the groove. The bending groove 34974 allows the block portion 34972 to open to a certain angle, facilitating removal of the tip detachment tube 3493. The transmission rod 3494 is driven up and down by a seventh drive mechanism. The seventh drive mechanism is a second screw drive mechanism, which includes an eighth screw and a tip detachment motor 3491. The screw's function is to convert rotational motion into linear motion. The eighth screw includes an eighth screw and an eighth nut threadedly engaged with the eighth screw. The eighth screw is connected to the rotating shaft of the tip detachment motor 3491 via a coupling. In this embodiment, a tenth sensing rod is fixed to the transmission rod 3494, which is connected to the eighth nut. However, the transmission rod 3494 can also be directly connected to the eighth nut. The tip detachment guide block 3495 has a tenth cavity formed therein for mounting the second screw drive mechanism, with the eighth screw located within the tenth cavity. The tip detachment motor 3491 is mounted on the tip detachment guide block 3495 or on the frame of the blood testing machine. In this embodiment, the tip detachment motor 3491 is mounted on the tip detachment guide block 3495, reducing the impact of vibrations from other components of the blood testing machine on the tip detachment motor 3491 during operation. This also allows the tip detachment motor 3491 to be combined with the other components of the pipette 349 to form a separate module, facilitating installation and removal. A tenth sliding hole is formed in the tip detachment guide block 3495, connecting to the tenth cavity. The tenth sensing rod passes through the tenth sliding hole and is connected to the eighth nut. The second screw drive mechanism is driven by the tip detachment motor 3491, resulting in low noise. The eighth screw and the tip detachment motor 3491 cooperate to achieve rigid transmission, ensuring timely and rapid transmission.

[0141] When a tip needs to be installed, the picker 2 grips the tip and places it on the tip positioning mechanism 35. The tip positioning mechanism 35 then moves the tip directly below the tip fixing tube 3492. The sixth drive mechanism then moves the pipette 349 downward until the fixing ramp 34921 is pressed into the tip, completing the tip installation. The picker 2 then moves the material directly below the tip for pipetting.

[0142] After the pipetting is completed, the used tip needs to be automatically detached. The seventh driving mechanism drives the transmission rod 3494 to move downward, and the tip detachment tube 3493 is also driven downward. Since the bottom of the tip detachment tube 3493 has a certain contact area with the head of the tip, the tip is also driven downward, the fixed inclined surface 34921 detaches from the tip, and the tip falls into the front waste funnel 302.

[0143] In the above technical solution, a blood collection tube guide block 346 is fixed to the lower portion of the capping back plate 348. An L-shaped capping slider 3413 is provided on the side of the blood collection tube guide block 346. The capping slider 3413 is driven by a second drive mechanism and can move along the blood collection tube guide block 346. The second drive mechanism is a third screw drive mechanism, which includes a ninth screw and a blood collection tube moving motor 345. The screw's function is to convert rotational motion into linear motion. The ninth screw includes a ninth screw and a ninth nut that engages with the ninth screw. The ninth screw is connected to the rotating shaft of the blood collection tube moving motor 345 via a coupling. An eleventh sensing rod is fixed to the capping slider 3413 and connected to the ninth nut. The blood collection tube guide block 346 contains an eleventh cavity for mounting the third screw drive mechanism, with the ninth screw located within the cavity. The blood collection tube moving motor 345 is mounted on the blood collection tube guide block 346 or on the frame of the blood collection tube testing machine. In this embodiment, the blood collection tube moving motor 345 is mounted on the blood collection tube guide block 346, reducing the vibrations from other components of the blood testing machine during operation. This also allows the blood collection tube moving motor 345 to be combined with the other components of the cap removal and code scanning mechanism 34 to form a separate module, facilitating installation and removal. The blood collection tube guide block 346 is provided with an eleventh sliding hole, which communicates with the eleventh cavity. The eleventh sensing rod passes through the eleventh sliding hole and connects to the ninth nut. The third screw drive mechanism is driven by the blood collection tube moving motor 345, resulting in low noise. The ninth screw and the blood collection tube moving motor 345 cooperate to achieve rigid transmission, ensuring rapid and timely transmission. The blood collection tube guide block 346 is equipped with a ninth limit sensor, a fifth origin sensor, and a tenth limit sensor. The ninth and tenth limit sensors are respectively fixed at opposite ends of a side surface of the blood collection tube guide block 346, with the fifth origin sensor located between the ninth and tenth limit sensors. The side surface of the blood collection tube guide block 346 where the ninth, fifth, and tenth limit sensors are located is not located on the left or right side of the blood collection tube guide block 346. Figure 19 、 20 Therefore, the ninth limit sensor, the fifth origin sensor and the tenth limit sensor are not displayed. Figure 19 、 20The ninth limit sensor, the fifth origin sensor, and the tenth limit sensor are used to sense the eleventh sensing rod. The blood collection tube moving motor 345 first drives the eleventh sensing rod to cooperate with the fifth origin sensor. When the fifth origin sensor senses the eleventh sensing rod, the blood collection tube moving motor 345 resets to its origin. The blood collection tube moving motor 345 then continues to drive the uncapping slider 3413 and the eleventh sensing rod to move. During the above process, when the ninth limit sensor senses the eleventh sensing rod, the blood collection tube moving motor 345 stops moving; when the tenth limit sensor senses the eleventh sensing rod, the blood collection tube moving motor 345 stops moving. Therefore, the ninth and tenth limit sensors limit the movement of the uncapping slider 3413.

[0144] In the above technical solution, a sixth electric gripper 500 is fixed longitudinally to the cap removal slider 3413, for gripping the tube body. Positioning fingers 347 are mounted on the gripper piston rods on both sides of the sixth electric gripper 500. These positioning fingers 347 are located directly below the tube cap gripper fingers 343. The opposing sides of the heads of the two positioning fingers 347 are each formed with an arc-shaped tube body gripping groove 3471, within which an elastomer is positioned. When the positioning fingers 347 grip the tube body, the elastomer compresses the tube body, ensuring a more secure grip. Due to the elasticity of the elastomer, the tube body is prevented from being overly squeezed and potentially ruptured. In this embodiment, the elastomer is polyurethane (PU), which offers advantages such as high strength and minimal compression deformation.

[0145] In the above technical solution, a cover-pulling sensor 3414 is also installed on the cover-pulling back plate 348 . The cover-pulling sensor 3414 is a photoelectric sensor, and the cover-pulling sensor 3414 corresponds to the circular hole 3433 .

[0146] When scanning the blood collection tube, the material picking device 2 clamps the blood collection tube and moves it between the blood collection tube cover clamping fingers 343 of the capping and code scanning mechanism 34. The fifth electric clamping claw 400 drives the blood collection tube cover clamping fingers 343 to clamp the blood collection tube; the ingredient rotating mechanism 39 on the top of the capping back plate 348 starts to operate, the blood collection tube starts to rotate, and the code scanner 3415 starts and reads the barcode information on the blood collection tube; until the code scanning is completed, the ingredient rotating motor 391 stops moving and the code scanning is completed.

[0147] When removing the cap from a blood collection tube, the removal device 2 moves the tube between the two tube cap gripping fingers 343. The fifth electric gripper 400 drives the tube cap gripping fingers 343 to grip the tube cap. The second drive mechanism drives the cap removal slider 3413 on the tube guide block 346 upward. This slider drives the positioning gripping fingers 347 upward until the bottom of the gripping groove 3471 in the tube body rests on the bottom of the tube body. The sixth electric gripper 500 then drives the positioning gripping fingers 347 to grip the tube body. The second drive mechanism then drives the cap removal slider 3413 on the tube guide block 346 downward. This slider drives the positioning gripping fingers 347 and the tube body within it downward. The tube cap is restrained by the cap removal step 3432, disengaging the tube body and retaining it within the positioning cavity 3461 of the tube cap gripping fingers 343, thus removing the cap from the tube. The ingredient rotating mechanism 39 on the top of the capping back plate 348 drives the fifth electric clamp 400 to rotate 90 degrees, so that the capping sensor 3414 is facing the circular hole 3433. The capping sensor 3414 senses whether the blood collection tube cap is retained in the blood collection tube cap clamping finger 343 through the circular hole 3433. If the capping sensor 3414 senses the blood collection tube cap, it means that the blood collection tube cap is successfully removed and the next step can be performed; if not, it means that the blood collection tube cap is not successfully removed, and the next step cannot be performed. The system alarm notifies manual processing.

[0148] In the above technical solution: Figure 24As shown, the tip positioning mechanism 35 includes a tip guide block 352 fixed to the mixing plate 301. An L-shaped tip slider 353 is mounted on the tip guide block 352. The tip slider 353 is driven by a third drive mechanism and can move along the tip guide block 352. The third drive mechanism is a fourth screw drive mechanism, which includes a tenth screw and a tip motor 351. The screw's function is to convert rotational motion into linear motion. The tenth screw includes a tenth screw and a tenth nut threadedly engaged with the tenth screw. The tenth screw is connected to the rotating shaft of the tip motor 351 via a coupling. A twelfth sensing rod is fixed to the tip slider 353 and connected to the tenth nut. A twelfth cavity is formed within the tip guide block 352 for mounting the fourth screw drive mechanism, with the tenth screw located within the cavity. The tip motor 351 is mounted on the tip guide block 352 or on the frame of the blood testing machine. In this embodiment, the tip motor 351 is mounted on the tip guide block 352, reducing the vibrations from other components of the blood testing machine during operation. This also allows the tip motor 351 to be combined with the other components of the tip positioning mechanism 35 to form a separate module, facilitating installation and removal. The tip guide block 352 is formed with a twelfth sliding hole, which communicates with the twelfth cavity. The twelfth sensing rod passes through the twelfth sliding hole and is connected to the tenth nut. The fourth screw drive mechanism is driven by the tip motor 351, resulting in low noise. The tenth screw and the tip motor 351 cooperate to achieve rigid transmission, ensuring rapid and timely transmission. The tip guide block 352 is equipped with an eleventh limit sensor, a sixth origin sensor, and a twelfth limit sensor. The eleventh and twelfth limit sensors are respectively fixed at opposite ends of a side surface of the tip guide block 352, with the sixth origin sensor located between the eleventh and twelfth limit sensors. The eleventh, sixth, and twelfth limit sensors sense the twelfth sensing rod. The suction head motor 351 first drives the twelfth sensing rod to align with the sixth origin sensor. When the sixth origin sensor senses the twelfth sensing rod, the suction head motor 351 returns to its origin. The suction head motor 351 then continues to drive the suction head slider 353 and the twelfth sensing rod. During this process, when the eleventh limit sensor senses the twelfth sensing rod, the suction head motor 351 stops moving. When the twelfth limit sensor senses the twelfth sensing rod, the suction head motor 351 also stops moving. Therefore, the eleventh and twelfth limit sensors limit the movement of the suction head slider 353.

[0149] In the above technical solution, a tip positioning plate 354 is fixed to the longitudinal portion of the tip slider 353. The tip positioning plate 354 includes a tip positioning rod 3541. The end of the tip positioning rod 3541 extends out of the tip slider 353 and is formed with a tip positioning hole. The material removal device 2 clamps the tip and places it into the tip positioning hole, waiting for it to be mated with the pipetting device 342. When the pipette 349 needs to be installed with a tip, the third drive mechanism drives the tip slider 353, the tip positioning plate 354, and the tip to move directly below the pipette 349, waiting for the pipette 349 to move downward and achieve an interference fit with the tip, completing the installation between the tip and the pipette 349. The pipette 349 then drives the tip upward, and the tip is disengaged from the tip positioning hole. The third drive mechanism drives the tip slider 353 and the tip positioning plate 354 away from the pipette 349.

[0150] In the above technical solution: Figure 25As shown, the specimen transport mechanism 36 includes a specimen guide block 362 horizontally fixed to the bottom of the ingredient plate 301. A specimen positioning slider 363 is disposed at the bottom of the specimen guide block 362. The specimen positioning slider 363 is driven by a fourth drive mechanism and can move along the specimen guide block 362. The fourth drive mechanism is a first synchronous wheel mechanism. The first synchronous wheel transmission mechanism includes a specimen motor 361, a thirteenth transmission shaft, and a fourteenth transmission shaft. The thirteenth transmission shaft is connected to the rotating shaft of the specimen motor 361 and the two are arranged in the same direction. The fourteenth transmission shaft is arranged parallel to the thirteenth transmission shaft. The thirteenth and fourteenth transmission shafts are each provided with a seventh synchronous wheel, and a seventh belt is interposed between the two seventh synchronous wheels. The seventh belt is fixed to a third connecting block. A thirteenth sensing rod is fixed to the specimen positioning slider 363, and the thirteenth sensing rod is connected to the third connecting block. A specimen transmission block 366 is mounted on one end of the specimen guide block 362. A first synchronous wheel transmission mechanism is installed within the specimen transmission block 366 and the specimen guide block 362. A thirteenth transmission shaft is disposed within the specimen transmission block 366, and the specimen motor 361 is mounted on the specimen transmission block 366 or on the frame of the blood testing machine. In this embodiment, the specimen motor 361 is mounted on the specimen transmission block 366, reducing the vibrations from other components of the blood testing machine during operation. This also allows the specimen motor 361 to form a separate module with the other components of the specimen transport mechanism 36, facilitating installation and removal. The specimen transmission block 366 positions the specimen motor 361 perpendicular to the specimen guide block 362, reducing its lateral dimensions and effectively utilizing excess vertical space, thereby reducing the overall machine footprint. A thirteenth cavity is formed within the specimen guide block 362, and the fourteenth transmission shaft is located at the end of the thirteenth cavity facing away from the specimen transmission block 366. The specimen guide block 362 also has a thirteenth sliding hole formed within it, which communicates with the thirteenth cavity. The thirteenth sensing rod passes through the thirteenth sliding hole and connects to the third connecting block. The first synchronous wheel transmission mechanism is driven by the specimen motor 361, resulting in low noise. The specimen motor 361 cooperates with the thirteenth and fourteenth transmission shafts, and the seventh belt to achieve flexible transmission, which is safer. The specimen guide block 362 is equipped with a thirteenth limit sensor, a seventh origin sensor, and a fourteenth limit sensor. The thirteenth and fourteenth limit sensors are respectively fixed at opposite ends of a side of the specimen guide block 362, with the seventh origin sensor located between the thirteenth and fourteenth limit sensors. The thirteenth, seventh, and fourteenth limit sensors are used to sense the thirteenth sensing rod. The specimen motor 361 first drives the thirteenth sensing rod to mate with the seventh origin sensor. When the seventh origin sensor senses the thirteenth sensing rod, the specimen motor 361 resets to its origin.Then the specimen motor 361 continues to drive the specimen positioning slider 363 and the thirteenth sensing rod to move; in the above process, when the thirteenth limit sensor senses the thirteenth sensing rod, the specimen motor 361 stops moving; when the fourteenth limit sensor senses the thirteenth sensing rod, the specimen motor 361 stops moving, so the thirteenth limit sensor and the fourteenth limit sensor play a limiting role in the movement of the specimen positioning slider 363.

[0151] In the above technical solution, a specimen positioning post mounting plate 364 is fixed to the bottom of the specimen positioning slider 363, to which a specimen positioning post 365 is fixed. A positioning bar hole is formed in the mating plate 301. The top of the specimen positioning post 365 passes through the positioning bar hole and is provided with a mating protrusion 3651. The mating protrusion 3651 is provided with a cup positioning groove for receiving the measuring cup 7. Due to testing requirements, the measuring cup 7 needs to be moved several times between the batching device 3 and the inspection device 5. However, due to the distance between the material removal device 2 and the material transfer device 4, direct transfer of the measuring cup 7 is not possible. Therefore, a specimen transport mechanism 36 is provided to facilitate the transfer of the measuring cup 7. The specimen guide block 362 has a testing end and a sample loading end, respectively. The specimen positioning post 365 and the measuring cup 7 are driven by a specimen motor 361 to move between the testing end and the sample loading end. When the specimen positioning post 365 moves to the sample loading end, the measuring cup 7 thereon is clamped by the material taking device 2; when the specimen positioning post 365 moves to the testing end, the measuring cup 7 thereon is clamped by the material moving device 4, and the cooperating protrusion 3651 shortens the distance between the material moving device 4 and the measuring cup 7, thereby preventing the material moving device 4 from being unable to clamp the measuring cup 7.

[0152] In the above technical solution: the measuring cup 7 includes a cup body 71 and a cup cover 72. Figure 26 As shown, the cup body 71 is a hollow structure, the cup mouth of the cup body 71 extends outwards and is formed with a circle of retaining edge 711, and the opening of the inner wall of the cup body 71 is formed into an inclined guide slope 712. Figure 27 As shown, the cup cover 72 includes a cover plate 721 and a fixing column 722 located in the center of the cover plate 721. The lower part of the fixing column 722 protrudes outward and forms an inclined cup cover step 7221 with the upper part. A cup cover groove 723 is formed in the center of the cover plate 721, and matching ribs are formed on the groove wall of the cup cover groove 723.

[0153] In the above technical solution: the reagent bottle positioning mechanism 37 is used to place the glass bottles P1, P2, and P3 containing various reagents required for blood testing. Figure 28 As shown, the reagent bottle positioning mechanism 37 includes a positioning base 371, which is in an I-shaped shape. The bottom of the positioning base 371 is fixed to the ingredient plate 301. The positioning base 371 is formed with a card slot 3711. The top of a pair of groove walls of the card slot 3711 protrudes inward to form a positioning strip 3712. A reagent bottle positioning fixture 372 is provided in the card slot 3711. Figure 29As shown, the reagent bottle positioning fixture 372 includes a fixing seat 3721 placed on the card slot 3711, a connecting column 3722 located above the fixing seat 3721, and a fixture seat 3723 located above the connecting column 3722. The fixture seat 3723 includes three fixture seat walls 37231 and a fixture groove 37232 surrounded by the three fixture seat walls 37231. The fixture groove 37232 is provided with an inclined seat block 373. Figure 30 As shown, the inclined seat block 373 includes a seat block wall 3731 and a seat block bottom 3732. The upper surface of the seat block bottom 3732 is formed into an inclined surface. The seat block bottom 3732 is located at the bottom of the fixture groove 37232. The seat block wall 3731 cooperates with the three-sided fixture seat wall 37231 to close the fixture seat 3723 on all four sides, preventing the glass bottles from falling. Moreover, since the bottom of the glass bottle contacts the upper surface of the seat block bottom 3732, each glass bottle is placed at an angle. When the material picking device 2 clamps the glass bottle for pipetting, it clamps the connecting column 3722, that is, the reagent bottle positioning fixture 372 and the reagent are pipetted synchronously. During pipetting, the reagent is always placed at an angle. Because the reagent is relatively expensive and usually in small quantities, the inclined position can fully utilize the reagent.

[0154] In the above technical solution, the reagent feeding mechanism 38 is used to place glass bottles containing other reagents required for blood testing, such as CaCl2 reagent, and the position of the reagent feeding mechanism 38 is close to the discharge door 3063 on the ingredient safety cover 306. Figure 31As shown, the reagent feeding mechanism 38 includes a feeding guide block 382 fixed to the ingredient plate 301. A feeding slider 383 is mounted on the feeding guide block 382. The feeding slider 383 is driven by a fifth drive mechanism and can move along the feeding guide block 382. The fifth drive mechanism is a second synchronous wheel transmission mechanism, which includes a feeding motor 381, a fifteenth transmission shaft, and a sixteenth transmission shaft. The fifteenth transmission shaft is connected to the rotating shaft of the feeding motor 381 and the two are arranged in the same direction. The sixteenth transmission shaft is arranged parallel to the fifteenth transmission shaft. The fifteenth and sixteenth transmission shafts are each equipped with an eighth synchronous wheel, and an eighth belt is interposed between the two eighth synchronous wheels. The eighth belt is fixed to the fourth connecting block. A fourteenth sensing rod is fixed to the feeding slider 383 and connected to the fourth connecting block. A feed transmission block 386 is mounted on one end of the feed guide block 382. A second synchronous wheel transmission mechanism is mounted within the feed transmission block 386 and the feed guide block 382. A fifteenth transmission shaft is disposed within the feed transmission block 386, and the feed motor 381 is mounted on the feed transmission block 386 or on the frame of the blood testing machine. In this embodiment, mounting the feed motor 381 on the feed transmission block 386 reduces vibrations from other components of the blood testing machine during operation. This also allows the feed motor 381 to form a separate module with the other components of the reagent feeding mechanism 38, facilitating installation and removal. The feed transmission block 386 positions the feed motor 381 perpendicular to the feed guide block 382, reducing its lateral dimensions and effectively utilizing excess vertical space, thereby reducing the overall machine footprint. A fourteenth cavity is formed within the feed guide block 382, with the sixteenth transmission shaft located at the end of the fourteenth cavity facing away from the feed transmission block 386. The feed guide block 382 also has a fourteenth sliding hole formed in it, which communicates with the fourteenth cavity. The fourteenth sensing rod passes through the fourteenth sliding hole and is connected to the fourth connecting block. The second synchronous wheel transmission mechanism is driven by the feed motor 381, resulting in low noise. The feed motor 381 cooperates with the fifteenth and sixteenth drive shafts, and the eighth belt to achieve flexible transmission, enhancing safety. In this embodiment, the feed guide block 382 is equipped with a fifteenth limit sensor, an eighth origin sensor, and a sixteenth limit sensor. The fifteenth and sixteenth limit sensors are respectively fixed at opposite ends of a side surface of the feed guide block 382, with the eighth origin sensor located between the fifteenth and sixteenth limit sensors. The fifteenth, eighth, and sixteenth limit sensors sense the fourteenth sensing rod. The feed motor 381 first drives the fourteenth sensing rod to mate with the eighth origin sensor. When the eighth origin sensor senses the fourteenth sensing rod, the feed motor 381 returns to its origin.Then the feeding motor 381 continues to drive the feeding slider 383 and the fourteenth sensing rod to move; in the above process, when the fifteenth limit sensor senses the fourteenth sensing rod, the feeding motor 381 stops moving; when the sixteenth limit sensor senses the fourteenth sensing rod, the feeding motor 381 stops moving, so the fifteenth limit sensor and the tenth limit sensor play a limiting role in the movement of the feeding slider 383.

[0155] In the technique scheme: the feeding slide block 383 is fixed with feeding mounting plate 384, the feeding mounting plate 384 is fixed with reagent feeding fixture 385, and the top of reagent feeding fixture 385 is shaped on reagent tank, and CaCl is housed in the reagent tank The vial of reagent.CaCl is contained in the vial of reagent and adopts manual feeding, and during feeding, manually presses control button 3062 and starts feeding motor 381, and reagent feeding fixture 385 is driven to move in the direction away from dispensing device 2, and after moving the set distance, the 5th driving mechanism stops motion.Manually open the discharge door 3063 on the batching safety cover 306 again, in the reagent tank, CaCl is housed in the vial of reagent.After feeding finishes, manually presses control button 3062 and starts the 5th driving mechanism, and reagent feeding fixture 385 is driven to move in the direction away from dispensing device 2, and after moving the set distance, the 5th driving mechanism stops motion, and CaCl is housed The vial of reagent waits for being clamped by dispensing device 2. The reagent feeding fixture 385 is set to be movable to prevent the material taking device 2 from grabbing the glass bottle containing the CaCl2 reagent and colliding with the operator's hand during manual loading, causing the operator's hand to be pinched or the material taking device 2 to be damaged.

[0156] In the above technical solution, the material transfer device 4 is responsible for transferring the test cup 7 between the specimen transport mechanism 36 and the inspection device 5. Figure 32 、 33 As shown, the material moving device 4 includes a horizontal material moving mechanism 41, a longitudinal material moving mechanism 42, an up and down material moving mechanism 43 and a material moving rotating mechanism 44. The material moving device 4 is placed in the rear frame 8 through a support frame 45, and a material moving bottom plate 46 is fixed on the support frame 45.

[0157] In the above technical solution: the transverse material shifting mechanism 41 includes a transverse material shifting guide block 411 fixed on the material shifting base plate 46, and a transverse material shifting slider 413 is provided on the transverse material shifting guide block 411. The transverse material shifting slider 413 is driven by the second transverse driving mechanism and can move along the transverse material shifting guide block 411. The second transverse driving mechanism is a third synchronous wheel transmission mechanism, which includes a transverse material shifting motor 412, a seventeenth transmission shaft, and an eighteenth transmission shaft. The seventeenth transmission shaft is connected to the rotating shaft of the transverse material shifting motor 412 and the two are set in the same direction. The eighteenth transmission shaft is set parallel to the seventeenth transmission shaft. The seventeenth transmission shaft and the eighteenth transmission shaft are both provided with a ninth synchronous wheel, and a ninth belt is provided between the two ninth synchronous wheels. The ninth belt is fixed with a fifth connecting block, and the transverse material shifting slider 413 is fixed with a fifteenth sensing rod, and the fifteenth sensing rod is connected to the fifth connecting block. A transverse material transfer block 414 is mounted on one end of the transverse material transfer guide block 411. A third synchronous wheel transmission mechanism is mounted within the transverse material transfer block 414 and the transverse material transfer guide block 411. The seventeenth transmission shaft is disposed within the transverse material transfer block 414. The transverse material transfer motor 412 is mounted on the transverse material transfer block 414 or on the frame of the blood testing machine. In this embodiment, the transverse material transfer motor 412 is mounted on the transverse material transfer block 414, thereby reducing the vibrations from other components of the blood testing machine when the transverse material transfer motor 412 is operating. Furthermore, the transverse material transfer motor 412 is combined with other components of the transverse material transfer mechanism 41 to form an independent module, making installation and disassembly easier. By arranging the transverse material transfer motor 412 perpendicular to the transverse material transfer guide block 411 through the transverse material transfer block 414, the transverse dimension can be reduced, the vertical height free space can be effectively utilized, and the space occupied by the entire machine can be reduced. A fifteenth cavity is formed in the transverse material shifting guide block 411, and the eighteenth transmission shaft is located at one end of the fifteenth cavity away from the transverse material shifting transmission block 414. A fifteenth sliding hole is also formed in the transverse material shifting guide block 411, and the fifteenth sliding hole is connected to the fifteenth cavity. The fifteenth sensing rod passes through the fifteenth sliding hole and is connected to the fifth connecting block. The third synchronous wheel transmission mechanism is driven by the transverse material shifting motor 412, which has low noise. The transverse material shifting motor 412 cooperates with the seventeenth transmission shaft, the eighteenth transmission shaft, and the ninth belt to achieve flexible transmission, which is safer. The seventeenth limit sensor, the ninth origin sensor, and the eighteenth limit sensor for sensing the fifteenth sensing rod are installed on the transverse material shifting guide block 411. The seventeenth limit sensor and the eighteenth limit sensor are respectively fixed at both ends of one side of the transverse material shifting guide block 411, and the ninth origin sensor is located between the seventeenth limit sensor and the eighteenth limit sensor. Start the transverse material moving motor 412, and the rotating shaft of the transverse material moving motor 412 drives the ninth belt to move through the cooperation between the seventeenth transmission shaft and the eighteenth transmission shaft, so that the ninth belt drives the transverse material moving slider 413 and the fifteenth sensing rod to move along the transverse material moving guide block 411.The transverse material moving motor 412 first drives the fifteenth sensing rod to move to cooperate with the ninth origin sensor. When the ninth origin sensor senses the fifteenth sensing rod, the transverse material moving motor 412 resets to the origin. The transverse material moving motor 412 then continues to drive the transverse material moving slider 413 and the fifteenth sensing rod to move. During the above process, when the seventeenth limit sensor senses the fifteenth sensing rod, the transverse material moving motor 412 stops moving. When the eighteenth limit sensor senses the fifteenth sensing rod, the transverse material moving motor 412 stops moving. Therefore, the seventeenth and eighteenth limit sensors limit the movement of the transverse material moving slider 413.

[0158] In the above technical solution, the longitudinal material shifting mechanism 42 includes a longitudinal material shifting guide block 421 fixed to the transverse material shifting slider 413 via a material shifting fixing plate 48. A longitudinal material shifting slider 423 is provided on the longitudinal material shifting guide block 421. The longitudinal material shifting slider 423 is driven by a second longitudinal drive mechanism and can move along the longitudinal material shifting guide block 421. The second longitudinal drive mechanism is a fifth composite transmission mechanism, which includes an eleventh threaded rod and a longitudinal material shifting motor 422. The longitudinal material shifting guide block 421 has a sixteenth cavity formed therein, and the eleventh threaded rod is located within the sixteenth cavity. The eleventh threaded rod includes an eleventh screw and an eleventh nut threadably engaged with the eleventh screw. A longitudinal material shifting transmission block 424 is mounted on the longitudinal material shifting guide block 421, and the longitudinal material shifting motor 422 is mounted on the longitudinal material shifting transmission block 424 or on the frame of the blood testing machine. In this embodiment, the longitudinal material moving motor 422 is installed on the longitudinal material moving transmission block 424, which reduces the vibration effect of other parts of the blood testing machine on the longitudinal material moving motor 422 when it is working; at the same time, the longitudinal material moving motor 422 is combined with other parts of the longitudinal material moving mechanism 42 to form an independent module, which is convenient for installation and disassembly. The longitudinal material moving transmission block 424 allows the longitudinal material moving motor 422 to be arranged parallel to the longitudinal material moving guide block 421, which can reduce the lateral size and effectively utilize the free space in the vertical height, thereby reducing the occupied space of the entire machine. The longitudinal material moving transmission block 424 is provided with a nineteenth transmission shaft and a twentieth transmission shaft. The nineteenth transmission shaft is fixed to the rotating shaft in the longitudinal material moving motor 422, and the twentieth transmission shaft is fixed to the eleventh screw in the longitudinal material moving guide block 421. The nineteenth transmission shaft and the twenty-first transmission shaft are both provided with a tenth synchronous wheel, and a tenth belt is sleeved between the two tenth synchronous wheels. A sixteenth sensing rod is fixed to the longitudinal material moving slider 423, and a sixteenth sliding hole is formed on the longitudinal material moving guide block 421. The sixteenth sliding hole is connected to the sixteenth cavity, and the sixteenth sensing rod passes through the sixteenth sliding hole and is connected to the eleventh nut. The longitudinal material moving guide block 421 is installed with a nineteenth limit sensor, a tenth origin sensor, and a twentieth limit sensor for sensing the sixteenth sensing rod. The nineteenth limit sensor and the twentieth limit sensor are respectively fixed at both ends of one side of the longitudinal material moving guide block 421, and the tenth origin sensor is located between the nineteenth limit sensor and the twenty-first limit sensor. The longitudinal material moving motor 422 is started, and the rotating shaft of the longitudinal material moving motor 422 drives the eleventh screw to rotate through the nineteenth transmission shaft, the tenth belt, and the twentieth transmission shaft. The eleventh screw drives the eleventh nut to move along the axial direction of the eleventh screw. The eleventh nut drives the longitudinal material moving slider 423 and the sixteenth sensing rod to move along the longitudinal material moving guide block 421. The longitudinal material moving motor 422 first drives the sixteenth sensing rod to move to cooperate with the tenth origin sensor. When the tenth origin sensor senses the sixteenth sensing rod, the longitudinal material moving motor 422 is reset to the origin.Then the longitudinal material moving motor 422 continues to drive the longitudinal material moving slider 423 and the sixteenth sensing rod to move; in the above process, when the nineteenth limit sensor senses the sixteenth sensing rod, the longitudinal material moving motor 422 stops moving; when the twentieth limit sensor senses the sixteenth sensing rod, the longitudinal material moving motor 422 stops moving, so the nineteenth limit sensor and the twentieth limit sensor play a limiting role in the movement of the longitudinal material moving slider 423.

[0159] In the above technical solution, the up-and-down material moving mechanism 43 includes an up-and-down material moving guide block 431 fixed to the longitudinal material moving slider 423 via a T-shaped material moving connecting plate 49. An L-shaped up-and-down material moving slider 433 is also provided on the up-and-down material moving guide block 431. The up-and-down material moving slider 433 is driven by a second up-and-down drive mechanism and can move along the up-and-down material moving guide block 431. The second up-and-down drive mechanism is a sixth composite transmission mechanism, which includes a twelfth screw and an up-and-down material moving motor 432. The up-and-down material moving guide block 431 defines a seventeenth cavity, the twelfth screw being located within the seventeenth cavity. The twelfth screw includes a twelfth screw and a twelfth nut threadably engaged with the twelfth screw. An up-and-down material moving transmission block 434 is mounted on the up-and-down material moving guide block 431, and the up-and-down material moving motor 432 is mounted on the up-and-down material moving transmission block 434 or on the frame of the blood testing machine. In this embodiment, the up and down material moving motor 432 is installed on the up and down material moving transmission block 434, which reduces the vibration of the up and down material moving motor 432 from other parts of the blood testing machine when the up and down material moving motor 432 is working; at the same time, the up and down material moving motor 432 is combined with other parts of the up and down material moving mechanism 43 to form an independent module, which is convenient for installation and disassembly. The up and down material moving transmission block 434 allows the up and down material moving motor 432 to be arranged parallel to the up and down material moving guide block 431, which can reduce the longitudinal dimension and effectively utilize the free space in the horizontal direction, thereby reducing the occupied space of the entire machine. The up and down material moving transmission block 434 is provided with a twenty-first transmission shaft and a twenty-second transmission shaft. The twenty-first transmission shaft is fixed to the rotating shaft in the up and down material moving motor 432, and the twenty-second transmission shaft is fixed to the twelfth screw in the up and down material moving guide block 431. The twenty-first transmission shaft and the twenty-second transmission shaft are both provided with an eleventh synchronous wheel, and an eleventh belt is sleeved between the two eleventh synchronous wheels. A seventeenth sensing rod is fixed to the transverse portion of the L-shaped upper and lower material moving slider 433. A seventeenth sliding hole is formed on the upper and lower material moving guide block 431. The seventeenth sliding hole is connected to the seventeenth cavity. The seventeenth sensing rod passes through the seventeenth sliding hole and is connected to the twelfth nut. The upper and lower material moving guide block 431 is equipped with a twenty-first limit sensor, an eleventh origin sensor, and a twenty-second limit sensor for sensing the seventeenth sensing rod. The twenty-first limit sensor and the twenty-second limit sensor are respectively fixed to the two ends of one side of the upper and lower material moving guide block 431, and the eleventh origin sensor is located between the twenty-first limit sensor and the twenty-second limit sensor. When the upper and lower material moving motor 432 is started, the rotating shaft of the upper and lower material moving motor 432 drives the twelfth screw to rotate through the twenty-first transmission shaft, the eleventh belt, and the twenty-second transmission shaft. The twelfth screw drives the twelfth nut to move along the axial direction of the twelfth screw. The twelfth nut drives the upper and lower material moving slider 433 and the seventeenth sensing rod to move along the upper and lower material moving guide block 431. The up-and-down material moving motor 432 first drives the seventeenth sensing rod to move to cooperate with the eleventh origin sensor. When the eleventh origin sensor senses the seventeenth sensing rod, the up-and-down material moving motor 432 is reset to the origin.Then the up and down material moving motor 432 continues to drive the up and down material moving slider 433 and the seventeenth sensing rod to move; in the above process, when the twenty-first limit sensor senses the seventeenth sensing rod, the up and down material moving motor 432 stops moving; when the twenty-second limit sensor senses the seventeenth sensing rod, the up and down material moving motor 432 stops moving, so the twenty-first limit sensor and the twenty-second limit sensor play a limiting role in the movement of the up and down material moving slider 433.

[0160] In the above technical solution: the material transfer rotation mechanism 44 includes a material transfer rotation transmission block 448 fixed to the top of the upper and lower material transfer sliders 433, and a material transfer rotation motor 441 is installed on the material transfer rotation transmission block 448. A third gear and a fourth gear that mesh with each other are horizontally arranged in the material transfer rotation transmission block 448. The third gear is fixed to the rotating shaft of the material transfer rotation motor 441, and a material transfer rotation sensing rod is fixed on the fourth gear. The top of the material transfer rotation sensing rod passes through the material transfer rotation transmission block 448 and is fixed with a rotating rod 442. A material transfer origin sensor 446 is fixed to the side of the material transfer rotation transmission block 448, and a material transfer origin sensing piece 447 corresponding to the material transfer origin sensor 446 is fixed to the side of the rotating rod 442. As the material transfer motor 441 drives the rotating rod 442 and the material transfer origin sensor 447 to rotate, when the material transfer origin sensor 446 senses the material transfer origin sensor 447, the material transfer motor 441 returns to its origin. The material transfer origin sensor 447 and the material transfer origin sensor 446 work together to ensure that the material transfer motor 441 returns to its origin after each rotation. A seventh electric gripper 600, used to grip the measuring cup 7, is fixed to the top of the rotating rod 442. The gripper piston rods on both sides of the seventh electric gripper 600 are each equipped with measuring cup gripping fingers 444. The two cup gripping fingers 444 are each formed with a cup gripping groove 4441 on the opposite side of their heads. The lower walls of the cup gripping grooves 4441 are formed with arcuate lower gripping notches 4443. These lower gripping notches 4443 are used to grip the outer wall of the cup body 71. After gripping, the ribs 711 and cup lid 72 are located within the cup gripping grooves 4441, preventing the cup lid 72 from separating from the cup body 71 during movement. In this embodiment, for ease of manufacturing, the upper walls of the cup gripping grooves 4441 are formed with arcuate upper gripping notches 4442. The heads of the two cup gripping fingers 444 are also formed with vertically upward-facing gripping finger support blocks 4444. The seventh electric gripper 600 is provided with a second analog sensor. When the seventh electric gripper 600 grips the measuring cup 7, the second analog sensor can determine which part of the measuring cup 7 is gripped by the degree of gripping by the seventh electric gripper 600. When the second analog sensor determines that the position gripped by the seventh electric gripper 600 is not the outer wall of the measuring cup 7, but the retaining edge 711 or other positions, the program automatically alarms and notifies manual processing. Otherwise, the measuring cup 7 may easily fall during the movement, causing damage to the measuring cup 7 and the inability to detect the processed blood sample in the measuring cup 7.

[0161] In the above technical solution: a material transfer drag chain box 47 is also provided on the support frame 45, a third drag chain fixing plate 471 is fixed on the material transfer bottom plate 46, a fourth drag chain fixing plate is fixed on the back of the transverse material transfer slider 413, and both ends of the material transfer drag chain box 47 are respectively fixed on the third drag chain fixing plate 471 and the fourth drag chain fixing plate. Figure 33 To prevent the material transfer chain box 47 from obstructing other components, it is not connected to the fourth chain fixing plate. The wires within the material transfer device 4 are located within the material transfer chain box 47, which protects and restrains the wires to facilitate their movement. Several foot cup assemblies 66 and caster assemblies 67 are mounted at the bottom of the support frame 45.

[0162] As an alternative to the first, second, third, fourth, fifth, and sixth composite transmission mechanisms, the first transverse drive mechanism, the first longitudinal drive mechanism, the first up-and-down drive mechanism, the first drive mechanism, the second longitudinal drive mechanism, and the second up-and-down drive mechanism may also employ any one of an oil cylinder, an air cylinder, a screw drive mechanism, a synchronous wheel drive mechanism, and a chain drive mechanism. As an alternative to the first, second, third, and fourth screw drive mechanisms, the sixth, seventh, second, and third drive mechanisms may also employ any one of an oil cylinder, an air cylinder, a synchronous wheel drive mechanism, a chain drive mechanism, and a composite transmission mechanism. As an alternative to the first, second, and third synchronous wheel drive mechanisms, the fourth, fifth drive mechanisms, and the second transverse drive mechanism may also employ any one of an oil cylinder, an air cylinder, a screw drive mechanism, a chain drive mechanism, and a composite transmission mechanism.

[0163] Since the connection relationship of the components in the first transverse driving mechanism, the first longitudinal driving mechanism, the first up-and-down driving mechanism, the second transverse driving mechanism, the second longitudinal driving mechanism, the second up-and-down driving mechanism, the first driving mechanism, the second driving mechanism, the third driving mechanism, the fourth driving mechanism, the fifth driving mechanism, the sixth driving mechanism, and the seventh driving mechanism are the same, without affecting the understanding of the technical solution, in order to avoid too much substantial repetition in the specification, the connection relationship of the alternative solution will be described in a general way, namely: the transverse material picking slider 212, the longitudinal material picking slider 223, the up-and-down material picking slider 233, the height adjustment slider 3193, the pipetting slider 3424, the transmission rod 3494, the capping slider 3 413, the tip slider 353, the specimen positioning slider 363, the feed slider 383, the lateral material moving slider 413, the longitudinal material moving slider 423, and the upper and lower material moving slider 433 are collectively referred to as sliders; the lateral material taking guide block 211, the longitudinal material taking guide block 221, the upper and lower material taking guide block 231, the reagent tube guide block 3192, the pipetting guide block 3422, the tip detachment guide block 3495, the blood collection tube guide block 346, the tip guide block 352, the specimen guide block 362, the feed guide block 382, the lateral material moving guide block 411, the longitudinal material moving guide block 421, and the upper and lower material moving guide block 431 are collectively referred to as guide blocks; the lateral material taking transmission block 214, the longitudinal material taking transmission block 224, the upper and lower material taking transmission block 237, the reagent tube guide block The tube transmission block 3194, the specimen transmission block 366, the feeding transmission block 386, the lateral material movement transmission block 414, the longitudinal material movement transmission block 424, and the up and down material movement transmission block 434 are collectively referred to as transmission blocks; the lateral material picking motor 213, the longitudinal material picking motor 222, the up and down material picking motor 232, the reagent tube moving motor 3191, the pipetting motor 3421, the tip detaching motor 3491, the blood collection tube moving motor 345, the tip motor 351, the specimen motor 361, the feeding motor 381, the lateral material movement motor 412, the longitudinal material movement motor 422, and the up and down material movement motor 432 are collectively referred to as motors; the first limit sensor and the second limit sensor, the third limit sensor and the fourth limit sensor, the fifth limit sensor 234 and the first limit sensor The sixth limit sensor 236, the seventh limit sensor and the eighth limit sensor, the ninth limit sensor and the tenth limit sensor, the eleventh limit sensor and the twelfth limit sensor, the thirteenth limit sensor and the fourteenth limit sensor, the fifteenth limit sensor and the sixteenth limit sensor, the seventeenth limit sensor and the eighteenth limit sensor, the twenty-first limit sensor and the twenty-second limit sensor are collectively referred to as limit sensors; the first origin sensor, the second origin sensor, the third origin sensor 235, the fourth origin sensor, the fifth origin sensor, the sixth origin sensor, the seventh origin sensor, the eighth origin sensor, the ninth origin sensor, the tenth origin sensor, and the eleventh origin sensor are collectively referred to as origin sensors.

[0164] When replaced by an oil or air cylinder, mounted on a guide block or the frame of the blood testing machine, the oil or air cylinder directly or indirectly drives the slider. This solution eliminates the need for an origin sensor and only requires a sensor mounted on the slider that cooperates with the limit sensor. This solution offers the advantage of a simple drive connection structure.

[0165] When replaced by a screw drive mechanism, the screw drive mechanism includes a first screw and a motor. The screw's function is to convert rotational motion into linear motion. The first screw includes a first screw and a first nut threadedly engaged with the first screw. The first screw is connected to the motor's rotating shaft via a coupling. A first sensing rod is fixed to the slider and connected to the first nut. A first cavity is formed within the guide block for mounting the screw drive mechanism, with the first screw located within the first cavity. The motor is mounted on the guide block or the frame of the blood testing machine. In this embodiment, mounting the motor on the guide block reduces the impact of vibration from other components of the blood testing machine during operation. It also allows the motor and other components of the screw drive mechanism to form a separate module, facilitating installation and removal. A first sliding hole is formed in the guide block, communicating with the first cavity. The first sensing rod passes through the first sliding hole and is connected to the first nut. Compared to the aforementioned oil or pneumatic cylinder transmission, the screw drive mechanism has the advantages of being driven by a motor, resulting in low noise. The first screw and motor cooperate to achieve rigid transmission, resulting in rapid and timely transmission.

[0166] When replaced by a synchronous wheel transmission mechanism, such as Figure 40As shown, the synchronous wheel transmission mechanism includes a motor, a first transmission shaft 01, and a second transmission shaft 02. The first transmission shaft 01 is connected to the motor's rotating shaft and oriented in the same direction. The second transmission shaft 02 is arranged parallel to the first transmission shaft 01. Both the first and second transmission shafts 01 and 02 are equipped with first synchronous wheels, and a first belt 03 is looped between the two first synchronous wheels. A first connecting block 04 is fixed to the first belt 03, and a second sensing rod is fixed to the slider, which is connected to the first connecting block 04. A transmission block is mounted at one end of the guide block. The synchronous wheel transmission mechanism is mounted within the transmission block and the guide block, with the first transmission shaft 01 positioned within the transmission block and the motor mounted on the transmission block or the frame of the blood testing machine. In this embodiment, the motor is mounted on the transmission block perpendicular to the guide block, reducing the impact of vibration from other components of the blood testing machine during operation. This also allows the motor and other components of the synchronous wheel transmission mechanism to form a separate module, facilitating installation and removal. A second cavity is formed within the guide block, with the second transmission shaft 02 located at the end of the second cavity away from the transmission block. The guide block also has a second sliding hole formed in it, communicating with the second cavity. The second sensing rod passes through the second sliding hole and connects to the first connecting block 04. The advantages of the synchronous wheel transmission mechanism are the same as those of the aforementioned screw transmission mechanism, driven by a motor and resulting in low noise. However, compared to the screw transmission mechanism, the motor cooperates with the first transmission shaft 01, the second transmission shaft 02, and the first belt 03 to achieve flexible transmission, which is safer. The transmission block allows the motor to be positioned perpendicular to the guide block, reducing the lateral dimensions and effectively utilizing the remaining vertical space, thereby reducing the overall machine footprint.

[0167] When a chain drive mechanism is used as a replacement, the chain drive mechanism includes a motor, a first gear, and a second gear. The gear shaft of the first gear is connected to the motor's rotating shaft and oriented in the same direction, while the gear shaft of the second gear is arranged parallel to the gear shaft of the first gear. A chain is interposed between the gear discs of the first and second gears. A second connecting block is fixed to the chain, and a third sensing rod is fixed to the slider, which is connected to the second connecting block. A transmission block is mounted at one end of the guide block. The chain drive mechanism is mounted within the transmission block and the guide block, with the first gear positioned within the transmission block and the motor mounted on the transmission block or the frame of the blood testing machine. In this embodiment, the motor is mounted on the transmission block and perpendicular to the guide block, reducing the impact of vibration from other components of the blood testing machine during operation. This also allows the motor and other components of the chain drive mechanism to form a separate module, facilitating installation and removal. A third cavity is formed within the guide block, with the second gear located at the end of the third cavity away from the transmission block. A third sliding hole is also formed within the guide block, communicating with the third cavity. The third sensing rod passes through the third sliding hole and connects to the second connecting block. The advantages of the chain transmission mechanism are the same as those of the above-mentioned synchronous wheel transmission mechanism. It is driven by a motor, has low noise, flexible transmission, and is safer. The transmission block allows the motor to be set perpendicular to the guide block, which can reduce the lateral size and effectively utilize the free space in the vertical height, thereby reducing the space occupied by the entire machine. Compared with the synchronous wheel transmission mechanism, the advantage is that the chain is not easy to wear.

[0168] When replaced by a compound transmission mechanism, such as Figure 41As shown, the composite transmission mechanism includes a motor, a second screw, a third transmission shaft 93, and a fourth transmission shaft 94. The screw's function is to convert rotational motion into linear motion. The second screw includes a second screw 91 and a second nut 92 threadedly engaged with the second screw 91. The third transmission shaft 93 is connected to the rotating shaft within the motor, and the fourth transmission shaft is connected to the second screw 91. Both the third and fourth transmission shafts 93 and 94 are equipped with second synchronous pulleys, with a second belt 95 positioned between the two second synchronous pulleys. A fourth sensing rod 96 is fixed to the cap removal slider 3413 and connected to the second nut 92. A transmission block is mounted on the guide block, and the composite transmission mechanism is mounted within the transmission block and the guide block. The third and fourth transmission shafts 93 and 94 are located within the transmission block. The guide block defines a fourth cavity, within which the second screw is located. The motor is mounted on the transmission block or on the frame of the blood testing machine. In this embodiment, the motor is mounted on the transmission block and arranged parallel to the guide block, reducing the impact of vibration from other components of the blood testing machine during operation. Furthermore, the motor and other components of the composite transmission mechanism form a separate module, facilitating installation and removal. The guide block is provided with a fourth sliding hole, which communicates with the fourth cavity. A fourth sensing rod 96 passes through the fourth sliding hole and connects to the second nut 92. When the motor is started, its shaft drives the second screw 91 to rotate via the third transmission shaft 93, the second belt 95, and the fourth transmission shaft 94. The second screw 91 then drives the second nut 92 axially along the second screw 91, which in turn drives the cap removal slider 3413 and the fourth sensing rod 96 along the guide block. The composite transmission mechanism has the same advantages as the aforementioned chain transmission mechanism: it is driven by a motor and produces low noise. However, compared to the chain transmission mechanism, the transmission block allows the motor to be arranged parallel to the guide block, reducing lateral dimensions and effectively utilizing excess vertical space, thereby reducing the overall machine footprint.

[0169] In the above technical solution, the first electric clamp 10, the second electric clamp 100, the third electric clamp 200, the fourth electric clamp 300, the fifth electric clamp 400, the sixth electric clamp 500, and the seventh electric clamp 600 all include a clamping cylinder 101 and clamping piston rods 102 located on both sides of the clamping cylinder 101. The clamping cylinder 101 is purchased directly from the market, and the internal structure of the clamping cylinder 101 is the existing technology. Only some adjustments are made to its external shape or structure in different usage scenarios. Figure 10 As shown, one end surface of the clamping electric cylinder 101 is provided with a concave clamping groove 1011, and the groove walls on both sides of the clamping groove 1011 are provided with protruding guide bars 1012, and a limit rod 1013 is provided in the middle of the guide bar 1012. Figure 11As shown, the bottom of the jaw piston rod 102 is formed with a guide shoe 1021, and a guide groove 1022 is formed on one side of the guide shoe 1021. The bottom of the guide groove 1022 is formed with an elongated limiting hole 1023. The guide shoes 1021 of both jaw piston rods 102 are located within the jaw groove 1011, the guide bar 1012 is located within the guide groove 1022, and the limiting rod 1013 passes through the limiting hole 1023. The jaw electric cylinder 101 drives the jaw piston rod 102 to move. During this process, the guide bar 1012 and the guide groove 1022 cooperate to guide the movement, and the limiting rod 1013 and the limiting hole 1023 cooperate to limit the movement.

[0170] In the above technical solution: Figure 32 As shown, the rear rack 8 includes a rear rack frame 81 and a power supply box located within the rear rack frame 81. A second sliding door 811 is provided on either side of the rear rack frame 81. A left rear panel 82 and a right rear panel 83 are fixed to either side of the top of the rear rack frame. The left rear panel 82 also has a rear waste hole, a rear waste funnel 84 mounted on the hole, and a rear waste channel connected below the rear waste funnel 84. Since the waste from the rear rack 8 contains blood, which can clot, the vertically arranged rear waste channel reduces the risk of blood clots sticking to the rear waste channel. Several foot cup assemblies 66 and caster assemblies 67 are mounted on the bottom of the rear rack 8.

[0171] In the above technical solution: Figure 35 As shown, the testing device 5 is secured to the left and right rear panels 82 and 83 via a testing base plate 51. A testing positioning plate 53 is secured to the testing base plate 51 via a screw jack 52. A thrombelastograph 54 is mounted on the testing positioning plate 53. The internal structure of the thrombelastograph 54, including components such as the circuit board, is conventional. The thrombelastograph 54 is used to monitor and analyze the coagulation state of a blood sample, thereby determining whether the sample has normal coagulation function. A test head 542 and a test seat 541 are provided on the thromboelastograph 54. Test connecting rods 543 are passed through both sides of the test seat 541. The top of the test connecting rod 543 is installed on the thromboelastograph 54. The test seat 541 can move up and down along the test connecting rods 543 on both sides. The test seat 541 is located directly below the test head 542. The test head 542 includes a test shaft 5421 and a test rod 5422. The test shaft 5421 is exposed at the bottom of the test head 542. The test shaft 5421 cooperates with the cup cover groove 723 of the cup cover 72. A switch groove 5423 is formed on the test head 542. One end of the test rod 5422 passes through the switch groove 5423. The switch groove 5423 includes a vertical groove and a horizontal groove perpendicular to the vertical groove. Figure 35The test rod 5422 is shown at the junction of the vertical and horizontal slots and in the off position. The bottom end of the vertical slot is the unloading end, and the right end of the horizontal slot is the testing end. The test base 541 is provided with a cup inspection slot 5411. During testing, the test cup 7 is positioned within the slot. A button 5412 is provided at the bottom of the test base 541. Pressing the button 5412 ejects the test cup 7 from the slot 5411.

[0172] In the above technical solution: a shift block mechanism 55 is also installed on the inspection positioning plate 53, and the shift block mechanism 55 is located below the inspection seat 541. Figure 36 As shown, the shifting mechanism 55 includes a shifting block base 551 with a sliding groove 5511 formed in the middle. Slots on either side of the sliding groove 5511 extend inward to form shifting block ribs 5512. A shifting block is positioned within the sliding groove 5511. The shifting block comprises a shifting block rod 5521 at the top, a shifting block seat 5522 at the bottom, and a trapezoidal block 5523 located between the shifting block rod 5521 and the shifting block seat 5522. A shifting block step is formed between the edge of the shifting block seat 5522 and the trapezoidal block 5523. The shifting block seat 5522 is located within the sliding groove 5511 and can move within the sliding groove 5511. The shifting block ribs 5512 are located on the shifting block step. The thromboelastograph 54 has two shifting block holes. The top of the shifting block rod 5521 passes through the shifting block hole and is formed with a semi-cylindrical shifting block groove 55211.

[0173] The testing device 5 is responsible for separating the empty test cup 7 from its cup body 71 and cup lid 721, as well as testing the processed blood sample. To separate the empty test cup 7, the retrieving device 2 grips the empty test cup 7 from the test cup loading conveyor line and moves it into the test cup positioning slot of the specimen transport mechanism 36. At this point, the specimen positioning post 365 of the specimen positioning mechanism 36 is located at the sample loading end. The fourth drive mechanism then drives the specimen positioning post 365 and the empty test cup 7 to the testing end. The material transfer device 4 grips the empty test cup 7 and moves it into the test cup inspection slot 5411 of the testing device 5. The test cup gripper fingers 444 of the material transfer device 4 then move below the inspection seat 541. The vertical material transfer mechanism 43 drives the test cup gripper fingers 444 upward, thereby moving the inspection seat 541 and the empty test cup 7 therein upward until the cup lid 721 is in close contact with the bottom of the test head 542. The test shaft 5421 is now located within the cup lid slot 723. Next, the cup gripping fingers 444 of the material transfer mechanism 4 move below the button 5412. They move upward, squeezing the button 5412 at the bottom of the test base 541, creating an interference fit between the mating ribs in the cup cover groove 723 and the test shaft 5421. The cup gripping fingers 444 then move above the test base 541, and the vertical material transfer mechanism 43 drives the cup gripping fingers 444 downward, thereby driving the test base 541 downward. At this point, the cup cover 72 is retained at the bottom of the test head 542, completing the separation of the cup cover 72 from the cup body 71. The measuring cup clamping finger 444 continues to move downward until the button 5412 is pressed by the top of the block rod 5521. The button 5412 ejects the empty cup body 71 from the measuring cup inspection slot 5411. The measuring cup clamping finger 444 grasps the empty cup body 71 and moves it to the measuring cup positioning slot of the specimen transport mechanism 36 to be tested. The fourth driving mechanism drives the specimen positioning column 365 and the empty cup body 71 to move to the sample loading end.

[0174] During testing, the material removal device 2 moves the loaded cup 71 onto the specimen transport mechanism 36. The fourth drive mechanism then drives the loaded cup 71 to the testing end. Simultaneously, the material transfer device 4 shifts the shifting block, positioning the shifting block slot 55211 directly below the button 5412. The material transfer device 4 then drives the cup gripping fingers 444 to grasp the loaded cup 71 and move it into the cup inspection slot 5411 of the testing device 5. They press the edges of the cup 71, ensuring that the cup 71 is fully seated within the slot 5411. During this process, the testing base 541 and the button 5412 at its base also move downward. The shifting block slot 55211 prevents the button 5412 from interfering with the shifting block rod 5521 during its downward movement. This would cause the button 5412 to be squeezed and eject the loaded cup 71 from the slot 5411, potentially spilling the liquid within the cup 71 and damaging the sample, making testing impossible. The cup gripper fingers 444 then move below the test seat 541 and move the test seat 541 upward until the upper surface of the test seat 541 is in close contact with the bottom of the test head 542. The material transfer device 4 then drives the gripper finger pusher 4444 to move the test rod 5422 to the detection end, and the test begins. The thromboelastograph 54 analyzes the specimen. After the analysis is completed, the gripper finger pusher 4444 moves the test rod 5422 to the off position and presses the test rod 5422 downward to the unloading end, causing the cup cover 72 to disengage from the test shaft 5421 and fall onto the cup body 71. The cup gripper fingers 444 then move the pusher block, causing the pusher block slot 55211 to move away from directly below the button 5412. The cup gripper fingers 444 then move the test seat 541 downward until the button 5412 is pressed by the top of the pusher block rod 5521. The button 5412 ejects the test cup 7 from the test cup inspection slot 5411, completing the test.

[0175] The working process of the present invention is as follows: first, blood samples are collected. Medical staff draw blood from the patient and put it into a blood collection tube, and then place the blood collection tube directly in the positioning fixture 16 in the vertical upward state on the first and second blood collection tube feeding conveyor lines, and place other materials in the corresponding positioning fixtures 16 in the vertical upward state on each feeding conveyor line.

[0176] Then the specimen is transported: press the start button 1921, the loading motors 18 of the ten loading conveyor lines start to operate, and the loading motors 18 drive the loading active shaft 12 to rotate through the transmission belt 17. The loading active shaft 12 and the loading driven shaft 13 cooperate to drive the loading conveyor belt 11 and the positioning fixture 16 to move toward the direction of the picking device 2, and manually continue to place materials on the positioning fixture 16 in a vertical upward state; when the positioning fixture 16 with the material is transferred to the input and discharge end, the first discharge sensor 15 senses the material and transmits the picking action instruction. After receiving the instruction, the picking device 2 clamps the material at the input and discharge end and moves to the set position to complete the loading.

[0177] Then the specimen is received: the barcode on the blood collection tube is scanned first to confirm which tests the blood sample needs to undergo, thereby confirming which reagents need to be added to the blood sample; the material taking device 2 clamps the blood collection tube and moves it between the blood collection tube cover clamping fingers 343 of the cap removal and code scanning mechanism 34, and the fifth electric clamp 400 drives the blood collection tube cover clamping fingers 343 to clamp the blood collection tube; the ingredient rotation mechanism 39 on the top of the cap removal back plate 348 starts to operate, the blood collection tube starts to rotate, and the code scanner 3415 starts and reads the barcode information on the blood collection tube; until the code scanning is completed, the ingredient rotation motor 391 stops moving, and the code scanning is completed.

[0178] The picking device 2 clamps the blood collection tube that has been scanned, and the fifth electric clamp 400 drives the clamping fingers 343 of the blood collection tube cover to move to both sides. The picking device 2 drives the blood collection tube to move between the two flipping clamping fingers 322 of the flipping mechanism 32. The fourth electric clamp 300 drives the flipping clamping fingers 322 to clamp the blood collection tube. The flipping motor 323 drives the flipping clamping fingers 322 and the blood collection tube to flip upside down three times, so that the blood sample therein is more uniform.

[0179] The material taking device 2 moves the flipped blood collection tube into the blood collection tube resting groove 3312 of the resting fixture 331 and leaves it to rest for one minute.

[0180] Blood collection tube cap removal: After the rest period, the retrieving device 2 grips the blood collection tube and moves it between the two blood collection tube cap gripping fingers 343. The fifth electric gripper 400 drives the blood collection tube cap gripping fingers 343 to grip the blood collection tube. The second drive mechanism drives the cap removal slider 3413 on the blood collection tube guide block 346 upward. The cap removal slider 3413 drives the positioning gripping fingers 347 upward until the bottom of the blood collection tube gripping groove 3471 is at the bottom of the blood collection tube body. The sixth electric gripper 500 drives the positioning gripping fingers 347 to grip the blood collection tube body. The second drive mechanism then drives the cap removal slider 3413 on the blood collection tube guide block 346 downward. The cap removal slider 3413 drives the positioning gripping fingers 347 and the blood collection tube body within the positioning gripping fingers 347 downward. The blood collection tube cap is restrained by the cap removal step 3432, disengaging the blood collection tube body and retaining it in the positioning cavity 3461 of the blood collection tube cap gripping fingers 343, thus removing the blood collection tube cap. The ingredient rotating mechanism 39 on the top of the capping back plate 348 drives the fifth electric clamp 400 to rotate 90 degrees, so that the capping sensor 3414 is facing the circular hole 3433. The capping sensor 3414 senses whether the blood collection tube cap is retained in the blood collection tube cap clamping finger 343 through the circular hole 3433. If the capping sensor 3414 senses the blood collection tube cap, it means that the blood collection tube cap is successfully removed and the next step can be performed; if not, it means that the blood collection tube cap is not successfully removed, and the next step cannot be performed. The system alarm notifies manual processing.

[0181] To draw a blood sample: The pick-up device 2 grips the large suction tip on the conveyor line and moves it to the tip positioning hole of the tip positioning mechanism 35. The third drive mechanism moves the large suction tip directly below the tip fixing tube 3492. The sixth drive mechanism then moves the pipette 349 downward until the fixing slope 34921 at the bottom of the tip fixing tube 3492 is pressed into the large suction tip, completing the installation of the large suction tip. The pick-up device 2 grips the uncapped blood collection tube and moves it under the large suction tip. The pipette 349 automatically draws the blood from the tube and retains it in the large suction tip.

[0182] Blood collection tube cover recovery: the material taking device 2 moves the blood collection tube back between the two positioning clamping fingers 347 of the uncapping and code scanning mechanism 34, and the sixth electric clamping claw 500 drives the positioning clamping fingers 347 to clamp the tube body of the blood collection tube. The second driving mechanism drives the uncapping slider 3413 on the blood collection tube guide block 346 to move up, and the uncapping slider 3413 drives the positioning clamping fingers 347 and the blood collection tube body inside the positioning clamping fingers 347 to move up, so that the tube mouth of the blood collection tube body is pressed back into the tube cap of the blood collection tube; when the material discharging sensor 110 senses the first and second blood collection tubes, the blood collection tube body is closed and the cover is closed. After there is no material placed on the positioning fixture 16 at the recovery and discharge end of the tube recovery conveyor line, a discharge action instruction is transmitted. After receiving the instruction, the picking device 2 clamps the covered blood collection tube and places it on the positioning fixture 16 on the first blood collection tube recovery conveyor line or the second blood collection tube recovery conveyor line. The loading motor 18 drives the loading active shaft 12 to rotate through the transmission belt 17. The loading active shaft 12 cooperates with the loading driven shaft 13 to drive the loading conveyor belt 11 and the positioning fixture 16 to move away from the picking device 2, thereby realizing the recovery of the blood collection tube.

[0183] Then the specimen is processed: according to the scan result, the reagents required for the test are added to the blood sample. This process is illustrated by the activated coagulation test. The reagents in the second reagent tube are needed in the activated coagulation test. First, the second reagent tube is opened. The material taking device 2 transfers the second reagent tube to between the two reagent tube cover clamping fingers 313 of the cap screwing mechanism 31. The second electric clamp 100 drives the two reagent tube cover clamping fingers 313 to clamp the tube cover of the second reagent tube. The height adjustment device 319 drives the reagent tube body clamping fingers 315 to rise, and the third electric clamp 200 drives the reagent tube body clamping fingers 315 to clamp the tube body of the second reagent tube. After clamping, the bottom of the second reagent tube body is tightly attached to the bottom of the fixed groove 3151. The dosing rotation motor 391 on top of the capping backplate 3101 is then activated, causing the reagent tube capping fingers 313 and the second reagent tube cap inside them to begin rotating. Simultaneously, the reagent tube body gradually descends, extending the tension spring 3113 until the second reagent tube body is completely free of the second reagent tube cap, completing the second reagent tube uncapping process. The second reagent tube cap remains within the reagent tube capping fingers 313. When the reagent tube body sensor 3119 detects the second reagent tube, it transmits a gripping instruction to the retrieving device 2, and the second reagent tube body awaits removal by the retrieving device 2.

[0184] The retrieving device 2 moves the uncapped second reagent tube beneath the pipette 349 of the uncapping and code scanning mechanism 34. The pipette 349 then transfers the entire blood sample from the large tip into the second reagent tube. After the second reagent tube is removed by the retrieving device 2, the pipette 349 automatically detaches from the large tip. The seventh drive mechanism drives the transmission rod 3492 downward, also moving the tip detachment tube 3493 downward. Because the bottom of the tip detachment tube 3493 has a certain contact surface with the head of the large tip, the large tip is also driven downward, causing the fixed ramp 34921 to detach from the large tip, and the large tip falls into the front waste funnel 302.

[0185] The second reagent tube is moved by the dispensing device 2 to the capping mechanism 31 for capping. The specific process is as follows: the dispensing device 2 moves the second reagent tube, containing the blood sample, between the reagent tube gripping fingers 315 of the capping mechanism 31. The third motorized gripper 200 drives the reagent tube gripping fingers 315 to grip the second reagent tube. The height adjustment device 319 raises the reagent tube gripping fingers 315 to the top of the tube, where they contact the bottom of the second reagent tube cap. At this point, the tension spring 3113 has not yet fully recovered, and its restoring force exerts an upward force on the second reagent tube. The dosing rotation motor 391 on top of the capping backplate 3101 is activated, causing the reagent tube capping fingers 313 and the second reagent tube cap inside them to begin rotating. When the threaded incisions between the second reagent tube cap and the second reagent tube body align, the second reagent tube body screws into the second reagent tube cap. Simultaneously, the restoring force of the tension spring 3113 drives the second reagent tube body upward, bringing it into close contact with the second reagent tube opening, completing the capping of the second reagent tube. When the reagent tube body sensor 3119 detects the second reagent tube, it transmits a gripping instruction to the retrieving device 2, and the second reagent tube awaits removal and recycling by the retrieving device 2.

[0186] The material removal device 2 drives the closed second reagent tube to move between the two flipping fingers 322 of the flipping mechanism 32. The fourth electric gripper 300 drives the flipping fingers 322 to clamp the second reagent tube. The flipping motor 323 drives the flipping fingers 322 and the second reagent tube to flip upside down five times, so that the blood sample and the reagent therein are completely mixed.

[0187] The material taking device 2 moves the flipped second reagent tube into the reagent tube resting groove 3311 of the resting fixture 331 and leaves it to rest for one minute.

[0188] While the second reagent tube remains stationary, the material removal device 2 picks up an empty test cup 7 from the test cup loading conveyor line and moves it into the test cup positioning slot of the specimen transport mechanism 36. At this point, the specimen positioning post 365 of the specimen positioning mechanism 36 is located at the sample loading end. The fourth drive mechanism then drives the specimen positioning post 365 and the empty test cup 7 to the testing end, and the material transfer device 4 picks up the empty test cup 7 and moves it into the test cup inspection slot 5411 of the inspection device 5. The test cup gripping fingers 444 of the material transfer device 4 then move below the inspection seat 541. The vertical material transfer mechanism 43 drives the test cup gripping fingers 444 upward, thereby moving the inspection seat 541 and the empty test cup 7 therein upward until the cup cover 721 is in close contact with the bottom of the test head 542. The test shaft 5421 is now located within the cup cover slot 723. Next, the cup gripping fingers 444 of the material transfer mechanism 4 move below the button 5412. They move upward, squeezing the button 5412 at the bottom of the test base 541, creating an interference fit between the mating ribs in the cup cover groove 723 and the test shaft 5421. The cup gripping fingers 444 then move above the test base 541, and the vertical material transfer mechanism 43 drives the cup gripping fingers 444 downward, thereby driving the test base 541 downward. At this point, the cup cover 72 is retained at the bottom of the test head 542, completing the separation of the cup cover 72 from the cup body 71. The measuring cup clamping finger 444 continues to move downward until the button 5412 is pressed by the top of the block rod 5521. The button 5412 ejects the empty cup body 71 from the measuring cup inspection slot 5411. The measuring cup clamping finger 444 grasps the empty cup body 71 and moves it to the measuring cup positioning slot of the specimen transport mechanism 36 to be tested. The fourth driving mechanism drives the specimen positioning column 365 and the empty cup body 71 to move to the sample loading end.

[0189] The retrieving device 2 grabs the small suction tip from the conveyor line and moves it into the suction tip positioning hole of the suction tip positioning mechanism 35. The third drive mechanism drives the small suction tip to move directly below the suction tip fixing tube 3492. The sixth drive mechanism drives the pipette 349 downward until the fixed slope 34921 at the bottom of the suction tip fixing tube 3492 is pressed into the small suction tip, completing the installation of the small suction tip. The retrieving device 2 then grabs the glass bottle containing the CaCl2 reagent from the reagent supply fixture 385 and moves it below the small suction tip. The pipette 349 automatically draws the CaCl2 reagent and retains it in the small suction tip. The retrieving device 2 then drives the CaCl2 reagent glass bottle back into the reagent tank of the reagent supply fixture 385. The retrieving device 2 then grabs the cup 71 on the specimen transport mechanism 36 and moves it below the small suction tip. The pipette 342 transfers all the CaCl2 reagent into the cup 71. The retrieving device 2 then moves the cup 71 back into the cup positioning slot of the specimen transport mechanism 36. The pipette 349 automatically releases the small tip, which falls into the front waste funnel 302. The retrieving device 2 re-grips the large tip from the conveyor line and moves it into the tip positioning hole of the tip positioning mechanism 35. The third drive mechanism drives the large tip to move directly below the tip fixing tube 3492. The sixth drive mechanism drives the pipette 349 downward until the fixing slope 34921 at the bottom of the tip fixing tube 3492 is pressed into the large tip, completing the installation of the large tip.

[0190] After the second reagent tube has been left to stand, the material taking device 2 clamps the second reagent tube and moves it into the cap screwing mechanism 31 to complete the opening of the cap. The second reagent tube with the removed cap is then moved under the large suction head. The large suction head automatically absorbs the mixed liquid in the second reagent tube. The material taking device 2 moves the second reagent tube back into the cap screwing mechanism 31 to complete the closing of the cap. The second reagent tube is then moved to the front waste funnel 302 for recycling.

[0191] The material taking device 2 clamps the cup body 71 on the sample transport mechanism 36 to be tested and moves it to the bottom of the large suction head. The pipette 349 transfers all the mixed liquid in the large suction head into the cup body 71, and the material taking device 2 moves it back to the sample transport mechanism 36 to be tested.

[0192] Finally, the test is performed on the machine: The fourth drive mechanism moves the loaded cup 71 to the testing end. Simultaneously, the material transfer device 4 shifts the shift block, positioning the shift block slot 55211 directly below the button 5412. The cup gripper fingers 444 grasp the loaded cup 71 and move it into the cup testing slot 5411 of the testing device 5. They press the edges of the cup 71, ensuring that it is fully seated within the slot. The cup gripper fingers 444 then move below the testing seat 541 and move it upward until the top surface of the seat 541 is in close contact with the bottom of the test head 542. The material transfer device 4 then drives the gripper finger push block 4444 to shift the test rod 5422 to the testing end. The test begins, and the thromboelastogram 54 analyzes the specimen.

[0193] After the analysis is complete, the gripper finger 4444 toggles the test rod 5422 to the off position and presses the test rod 5422 downward, moving it to the unloading end, causing the cup cover 72 to disengage from the test shaft 5421 and fall onto the cup body 71. The cup gripper finger 444 toggles the shift block, moving the shift block slot 55211 away from directly below the button 5412. The cup gripper finger 444 then drives the inspection seat 541 downward until the button 5412 is pressed by the top of the shift block rod 5521. The button 5412 ejects the test cup 7 from the test cup inspection slot 5411. The cup gripper finger 444 then grabs the tested test cup 7 and moves it to the rear waste hopper 84, completing a test process.
