[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-11 As shown, the blood testing machine of the present invention 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 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 materials, the dispensing device 2 grips 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.

[0039] In the above technical solution: Figure 3As shown, the rear rack 8 includes a rear rack frame 81 and a power supply box located within the rear rack frame 81. Sliding doors 811 are 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 is mounted on the rear waste hole, and a rear waste channel is connected below the rear waste funnel 84. Since the waste from the rear rack 8 contains blood, which may clot, the vertically arranged rear waste channel reduces the risk of blood clots sticking to the rear waste channel.

[0040] In the above technical solution: the material transfer device 4 is responsible for transferring the measuring cup. Figure 3 、 4 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.

[0041] In the above technical solution: Figure 4 、 5As shown in Figures 11, the transverse material shifting mechanism 41 includes a transverse material shifting guide block 411 fixed on the material shifting base plate 46. 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 transverse driving mechanism and can move along the transverse material shifting guide block 411. The transverse driving mechanism is a first synchronous wheel transmission mechanism, which includes a transverse material shifting motor 412, a first transmission shaft 01 and a second transmission shaft 02. The first transmission shaft 01 is connected to the rotating shaft of the transverse material shifting motor 412 and the two are set in the same direction. The second transmission shaft 02 is set parallel to the first transmission shaft 01. A first synchronous wheel is provided on each of the first transmission shaft 01 and the second transmission shaft 02. A first belt 03 is sleeved between the two first synchronous wheels. A first connecting block 04 is fixed on the first belt 03. A second sensing rod is fixed on the transverse material shifting slider 413. The second sensing rod is connected to the first connecting block 04. A transverse material shifting transmission block 414 is installed at one end of the transverse material shifting guide block 411, and a first synchronous wheel transmission mechanism is installed in the transverse material shifting transmission block 414 and the transverse material shifting guide block 411, wherein the first transmission shaft 01 is set in the transverse material shifting transmission block 414, and the transverse material shifting motor 412 is installed on the transverse material shifting transmission block 414 or the frame of the blood testing machine. In this embodiment, the transverse material shifting motor 412 is installed on the transverse material shifting transmission block 414, which reduces the vibration of the transverse material shifting motor 412 from other parts of the blood testing machine when the transverse material shifting motor 412 is working; at the same time, the transverse material shifting motor 412 is combined with other parts of the transverse material shifting mechanism 41 to form an independent module, which is convenient for installation and disassembly. The transverse material shifting transmission block 414 allows the transverse material shifting motor 412 to be set perpendicular to the transverse material shifting guide block 411, which can reduce the transverse size and effectively utilize the free space in the vertical height, thereby reducing the occupied space of the entire machine. A second cavity is formed in the lateral material shifting guide block 411, and the second transmission shaft 02 is located at one end of the second cavity away from the lateral material shifting transmission block 414. A second sliding hole is also formed in the lateral material shifting guide block 411, and the second sliding hole is connected to the second cavity. The second sensing rod passes through the second sliding hole and is connected to the first connecting block 04. The first synchronous wheel transmission mechanism is driven by the lateral material shifting motor 412, which has low noise. The lateral material shifting motor 412 cooperates with the first transmission shaft 01, the second transmission shaft 02, and the first belt 03 to achieve flexible transmission, which is safer. A first limit sensor, a first origin sensor, and a second limit sensor for sensing the second sensing rod are installed on the lateral material shifting guide block 411. The first limit sensor and the second limit sensor are respectively fixed at both ends of one side of the lateral material shifting guide block 411, and the first origin sensor is located between the first limit sensor and the second limit sensor. Start the transverse material moving motor 412, and the rotating shaft of the transverse material moving motor 412 drives the first belt 03 to move through the cooperation between the first transmission shaft 01 and the second transmission shaft 02, so that the first belt 03 drives the transverse material moving slider 413 and the second sensing rod to move along the transverse material moving guide block 411.The lateral material moving motor 412 first drives the second sensing rod to move to mate with the first origin sensor. When the first origin sensor senses the second sensing rod, the lateral material moving motor 412 resets to its origin. The lateral material moving motor 412 then continues to drive the lateral material moving slider 413 and the second sensing rod to move. During the above process, when the first limit sensor senses the second sensing rod, the lateral material moving motor 412 stops moving. When the second limit sensor senses the second sensing rod, the lateral material moving motor 412 stops moving. Therefore, the first and second limit sensors limit the movement of the lateral material moving slider 413.

[0042] As an alternative to the above-mentioned first synchronous wheel transmission mechanism, the transverse drive mechanism can also adopt a first composite transmission mechanism. The first composite transmission mechanism includes a fourth motor, a second screw, a third transmission shaft 93 and a fourth transmission shaft 94. The function of the screw is to convert rotational motion into linear motion. In this embodiment, the fourth motor is a transverse material moving motor 412. 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 in the fourth motor, and the fourth transmission shaft is connected to the second screw 91. A second synchronous wheel is provided on the third transmission shaft 93 and the fourth transmission shaft 94, and a second belt 95 is provided between the two second synchronous wheels. A fourth sensing rod 96 is fixed on the cover removal slider 3413, and the fourth sensing rod 96 is connected to the second nut 92. A transverse material transfer block 414 is mounted on the transverse material transfer guide block 411. A first composite transmission mechanism is mounted within the transverse material transfer block 414 and the transverse material transfer guide block 411. The third transmission shaft 93 and the fourth transmission shaft 94 are located within the transverse material transfer block 414. A fourth cavity is formed within the transverse material transfer guide block 411, and the second screw is located within the fourth cavity. A fourth motor is mounted on the transverse material transfer block 414 or on the frame of the blood testing machine. In this embodiment, the fourth motor is mounted on the transverse material transfer block 414 and arranged parallel to the transverse material transfer guide block 411, thereby reducing the vibration effects of other components of the blood testing machine on the fourth motor during operation. At the same time, the fourth motor and the other components of the first composite transmission mechanism are combined to form an independent module, facilitating installation and disassembly. A fourth sliding hole is formed in the transverse material transfer guide block 411, which is connected to the fourth cavity. The fourth sensing rod 96 passes through the fourth sliding hole and is connected to the second nut 92. The fourth motor is started, and 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 drives the second nut 92 to move axially along the second screw 91. The second nut 92 drives the capping slider 3413 and the fourth sensing rod 96 to move along the transverse material moving guide block 411. The advantages of the first composite transmission mechanism are the same as those of the first synchronous wheel transmission mechanism described above, namely, it is driven by the fourth motor and produces low noise. However, compared to the first synchronous wheel transmission mechanism, the advantage is that the transverse material moving transmission block 414 allows the fourth motor to be arranged parallel to the transverse material moving guide block 411, which can reduce the transverse dimension, effectively utilize the free vertical space, and thus reduce the space occupied by the entire machine.

[0043] 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 longitudinal drive mechanism and can move along the longitudinal material shifting guide block 421. The longitudinal drive mechanism is a second composite transmission mechanism, which includes a third screw and a longitudinal material shifting motor 422. A fifth cavity is formed within the longitudinal material shifting guide block 421. The third screw is located within the fifth cavity. The third screw includes a third screw and a third nut threadedly engaged with the third screw. A longitudinal material shifting transmission block 424 is mounted on the longitudinal material shifting guide block 421. 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. A fifth transmission shaft and a sixth transmission shaft are provided in the longitudinal material moving transmission block 424. The fifth transmission shaft is fixed to the rotating shaft in the longitudinal material moving motor 422, and the sixth transmission shaft is fixed to the third screw in the longitudinal material moving guide block 421. A third synchronous wheel is provided on both the fifth transmission shaft and the sixth transmission shaft, and a third belt is provided between the two third synchronous wheels. A fifth sensing rod is fixed to the longitudinal material moving slider 423, and a fifth sliding hole is formed on the longitudinal material moving guide block 421. The fifth sliding hole is connected to the fifth cavity, and the fifth sensing rod passes through the fifth sliding hole and is connected to the third nut. The longitudinal material moving guide block 421 is equipped with a third limit sensor, a second origin sensor, and a fourth limit sensor for sensing the fifth sensing rod. The third limit sensor and the fourth limit sensor are respectively fixed at the two ends of one side of the longitudinal material moving guide block 421, and the second origin sensor is located between the third limit sensor and the fourth limit sensor. The longitudinal material moving motor 422 is started, and the rotating shaft of the longitudinal material moving motor 422 drives the third screw to rotate through the fifth transmission shaft, the third belt, and the sixth transmission shaft. The third screw drives the third nut to move along the axial direction of the third screw. The third nut drives the longitudinal material moving slider 423 and the fifth sensing rod to move along the longitudinal material moving guide block 421. The longitudinal material moving motor 422 first drives the fifth sensing rod to move to cooperate with the second origin sensor. When the second origin sensor senses the fifth 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 fifth sensing rod to move; in the above process, when the third limit sensor senses the fifth sensing rod, the longitudinal material moving motor 422 stops moving; when the fourth limit sensor senses the fifth sensing rod, the longitudinal material moving motor 422 stops moving, so the third limit sensor and the fourth limit sensor play a limiting role in the movement of the longitudinal material moving slider 423.

[0044] 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 the up-and-down drive mechanism and can move along the up-and-down material moving guide block 431. The up-and-down drive mechanism is a third composite transmission mechanism, comprising a fourth screw and an up-and-down material moving motor 432. A sixth cavity is formed within the up-and-down material moving guide block 431, within which a fourth screw is located. The fourth screw comprises a fourth screw and a fourth nut threadedly engaged with the fourth 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 components 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 seventh transmission shaft and an eighth transmission shaft. The seventh transmission shaft is fixed to the rotating shaft in the up and down material moving motor 432, and the eighth transmission shaft is fixed to the fourth screw in the up and down material moving guide block 431. The seventh transmission shaft and the eighth transmission shaft are both provided with fourth synchronous wheels, and a fourth belt is sleeved between the two fourth synchronous wheels. A sixth sensing rod is fixed to the transverse portion of the L-shaped up and down material moving slider 433, and a sixth sliding hole is formed on the up and down material moving guide block 431. The sixth sliding hole is connected to the sixth cavity, and the sixth sensing rod passes through the sixth sliding hole and is connected to the fourth nut. The up and down material moving guide block 431 is installed with a fifth limit sensor, a third origin sensor, and a sixth limit sensor for sensing the sixth sensing rod. The fifth limit sensor and the sixth limit sensor are respectively fixed to the two ends of one side of the up and down material moving guide block 431, and the third origin sensor is located between the fifth limit sensor and the sixth limit sensor. The up and down material moving motor 432 is started, and the rotating shaft of the up and down material moving motor 432 drives the fourth screw to rotate through the seventh transmission shaft, the fourth belt, and the eighth transmission shaft. The fourth screw drives the fourth nut to move along the axial direction of the fourth screw. The fourth nut drives the up and down material moving slider 433 and the sixth sensing rod to move along the up and down material moving guide block 431. The up-and-down material moving motor 432 first drives the sixth sensing rod to move to cooperate with the third origin sensor. When the third origin sensor senses the sixth 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 sixth sensing rod to move; in the above process, when the fifth limit sensor senses the sixth sensing rod, the up and down material moving motor 432 stops moving; when the sixth limit sensor senses the sixth sensing rod, the up and down material moving motor 432 stops moving, so the fifth limit sensor and the sixth limit sensor play a limiting role in the movement of the up and down material moving slider 433.

[0045] As an alternative to the second and third composite transmission mechanisms described above, the longitudinal drive mechanism and the vertical drive mechanism can also adopt a second synchronous wheel transmission mechanism. Since the connection relationship between the components in the longitudinal drive mechanism and the vertical drive mechanism is the same, and without affecting the understanding of the technical solution, in order to avoid too much essentially repeated content in the specification, the connection relationship of the alternative solution will be described in a general way below, namely: the longitudinal material shifting slider 423 and the vertical material shifting slider 433 are collectively referred to as sliders, the longitudinal material shifting transmission block 424 and the vertical material shifting transmission block 434 are collectively referred to as transmission blocks, the longitudinal material shifting guide block 421 and the vertical material shifting guide block 431 are collectively referred to as guide blocks, and the longitudinal material shifting motor 422 and the vertical material shifting motor 432 are collectively referred to as motors. The second synchronous wheel transmission mechanism includes a motor, a ninth transmission shaft, and a tenth transmission shaft. The ninth transmission shaft is connected to the rotating shaft of the motor and the two are arranged in the same direction. The tenth transmission shaft is arranged parallel to the ninth transmission shaft. The ninth transmission shaft and the tenth transmission shaft are both provided with a fifth synchronous wheel, and a fifth belt is sleeved between the two fifth synchronous wheels. A third connecting block is fixed on the fifth belt, a seventh sensing rod is fixed on the slider, and the seventh sensing rod is connected to the third connecting block. A transmission block is installed at one end of the guide block, and a second synchronous wheel transmission mechanism is installed in the transmission block and the guide block, wherein the ninth transmission shaft is arranged in the transmission block, and the motor is installed on the transmission block or the frame of the blood testing machine. In this embodiment, the motor is installed on the transmission block and is arranged perpendicular to the guide block, which reduces the vibration of the motor from other parts of the blood testing machine when the motor is working; at the same time, the motor and other parts of the synchronous wheel transmission mechanism are combined to form an independent module, which is convenient for installation and disassembly. A seventh cavity is formed in the guide block, and the tenth transmission shaft is located at the end of the seventh cavity away from the transmission block. A seventh sliding hole is also formed in the guide block, and the seventh sliding hole is connected to the seventh cavity. The seventh sensing rod passes through the seventh sliding hole and is connected to the third connecting block. The advantages of the second synchronous wheel transmission mechanism are the same as those of the second and third compound transmission mechanisms mentioned above. It is driven by a motor and has low noise. Compared with the second and third compound transmission mechanisms, the advantage is that the motor cooperates with the ninth transmission shaft, the tenth transmission shaft, and the fifth belt to achieve flexible transmission, which is safer. The motor is set perpendicular to the guide block through the transmission block, 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.

[0046] As an alternative to the first, second and third composite transmission mechanisms, the transverse drive mechanism, the longitudinal drive mechanism and the up and down drive mechanism may also adopt any one of an oil cylinder, an air cylinder, a screw drive mechanism and a chain drive mechanism. Since the connection relationship of the various components in the transverse drive mechanism, the longitudinal drive mechanism, and the upper and lower drive mechanism is the same, without affecting the understanding of the technical solution, in order to avoid too much essentially repeated content in the specification, a general expression will be adopted when describing the connection relationship of the alternative scheme below, namely: the transverse 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 transverse material moving transmission block 414, the longitudinal material moving transmission block 424 and the upper and lower material moving transmission block 434 are collectively referred to as transmission blocks, the transverse 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 transverse material moving motor 412, the longitudinal material moving motor 422 and the upper and lower material moving motor 432 are collectively referred to as motors, the first origin sensor, the second origin sensor and the third origin sensor are collectively referred to as origin sensors, the first limit sensor and the second limit sensor, the third limit sensor and the fourth limit sensor, the fifth limit sensor and the sixth limit sensor are collectively referred to as limit sensors.

[0047] 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.

[0048] 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 on 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. The advantages of the screw drive mechanism are similar to those of the aforementioned composite transmission mechanism: it is driven by a motor and therefore produces low noise. However, compared to the composite transmission mechanism, it has the advantages of a simpler structure, with the first screw and motor cooperating to achieve rigid transmission, resulting in rapid and timely transmission.

[0049] 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 compound transmission mechanism. It is driven by a motor and has low noise. Compared with the compound transmission mechanism, the advantage is that the motor cooperates with the first gear, the second gear, and the chain to achieve flexible transmission, which is safer. The motor is set perpendicular to the guide block through the transmission block, 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.

[0050] 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 first gear and a second gear that are meshed with each other are horizontally arranged in the material transfer rotation transmission block 448. The first 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 second 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. In the process of the material moving rotating motor 441 driving the rotating rod 442 and the material moving origin sensing piece 447 to rotate, when the material moving origin sensor 446 senses the material moving origin sensing piece 447, the material moving rotating motor 441 resets to the origin. The material moving origin sensing piece 447 and the material moving origin sensor 446 are used together to ensure that the material moving rotating motor 441 can return to the origin after each rotation.

[0051] In the above technical solution, an electric gripper 600 for gripping a measuring cup is fixed to the top of the rotating rod 442. The electric gripper 600 includes a gripper cylinder 101 and gripper piston rods 102 located on both sides of the gripper cylinder 101. The gripper cylinder 101 is purchased directly from the market. The internal structure of the gripper cylinder 101 is based on existing technology, with only some adjustments to its external shape or structure for different usage scenarios. Figure 8 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 9 As 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.

[0052] In the above technical solution: the measuring cup includes a cup body 71 and a cup cover 72. Figure 6 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 7 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.

[0053] In the above technical solution, cup gripping fingers 444 are mounted on the gripper piston rods 102 on both sides of the electric gripper 600. Cup gripping grooves 4441 are formed on the opposing sides of the heads of the two cup gripping fingers 444. The lower walls of the 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 the cup cover 72 are located within the cup gripping grooves 4441, preventing the cup cover 72 from separating from the cup body 71 during movement. In this embodiment, for ease of processing, arcuate upper gripping notches 4442 are formed on the upper walls of the grooves 4441. The heads of the two cup gripping fingers 444 are also formed with vertically upward-facing gripping finger support blocks 4444. These support blocks 4444 facilitate contact between the cup gripping fingers 444 and other components of the material transfer device 4, thereby driving the movement of these components.

[0054] In the above technical solution, the electric gripper 600 is equipped with an analog sensor. When the electric gripper 600 grasps the measuring cup, the analog sensor determines the specific part of the measuring cup being grasped by the electric gripper 600 based on the degree of grip. If the analog sensor determines that the electric gripper 600 is not grasping the outer wall of the measuring cup, but rather the retaining edge 711 or another location, the program automatically issues an alarm and notifies manual intervention. Otherwise, the measuring cup could easily fall during movement, resulting in damage to the measuring cup and the inability to test the processed blood sample within the measuring cup. The analog sensor in this invention is conventional technology.

[0055] In the above technical solution: a material transfer drag chain box 47 is also provided on the support frame 45, a first drag chain fixing plate 471 is fixed on the material transfer bottom plate 46, a second drag chain fixing plate is fixed on the back of the horizontal material transfer slider 413, and both ends of the material transfer drag chain box 47 are respectively fixed on the first drag chain fixing plate 471 and the second drag chain fixing plate. Figure 4 In order to prevent the material shifting drag chain box 47 from blocking other components, the material shifting drag chain box 47 is not connected to the second drag chain fixing plate. The wires in the material shifting device 4 are all located in the material shifting drag chain box 47, which is used to protect and constrain the wires to facilitate their movement.

[0056] The loading device 1 begins loading. The retrieving device 2 picks up the materials and moves them to the designated position of the batching device 3. The blood collection tube is also moved to the designated position of the batching device 3 by the retrieving device 2. The retrieving device 2 also drives the blood collection tube, measuring cup, and other materials within the batching device 3. The blood in the blood collection tube is sampled by the batching device 3 and the required test reagents are added to form the test specimen. Next, the lateral material movement mechanism 41, longitudinal material movement mechanism 42, vertical material movement mechanism 43, and material movement rotation mechanism 44 cooperate to move the measuring cup gripper fingers 444 to the vicinity of the measuring cup. The gripper electric cylinder 101 drives the gripper piston rod 102 from both sides toward the center. The measuring cup gripper fingers 444 also move from both sides toward the center and grip the measuring cup on the batching device 3. The lateral material movement mechanism 41, longitudinal material movement mechanism 42, vertical material movement mechanism 43, and material movement rotation mechanism 44 cooperate to drive the measuring cup gripper fingers 444 and the measuring cup into the testing device 5, which separates the cup body 71 from the cup lid 72. The present invention drives the cup body 71 to move back into the batching device 3, and the batching device 3 moves the sample to be tested into the cup body 71. The present invention moves the cup body 71 containing the sample to be tested into the testing device 5 for blood testing, completing a testing process.
