Once the post-processing system is ready, it sends a message to the sample buffer device 102, instructing it to transfer the sample rack assembly 107 from right to left to the first conveyor belt 210 of the sample transfer layer 2, and stop it on the first conveyor belt 210 via the horizontal deflector component 220. The horizontal deflector component 220 then slides the sample rack assembly 107 step-by-step along the conveyor belt from right to left. With each step, the sample container 1072 scanning component 230 checks the location of the sample container 1072 on the sample rack assembly 107 to confirm the presence or absence of the sample container 1072. When a sample container 1072 is detected, the scanning component 230 identifies and reads the sample container ID 1074 and sends the reading result to the host computer 106. The sample rack ID 1073 obtained in the sample buffer device 102 is combined with the sample container ID 1074 obtained from the sample container 1072 scanning component 230 to form the sample post-processing ID information H7. Subsequently, the sample rack assembly 107 continues to be conveyed to the left to the position of the lifting mechanism, and the lifting component 250 lifts the sample rack assembly 107 from the sample transmission layer 2 to the sample classification storage layer 3. At this time, the host computer 106 compares the sample pre-processing ID information H6 with the sample post-processing ID information H7, and issues corresponding action commands to the robot arm motion layer 4 according to the sample test instructions and test results. The robot arm 40, described later, transfers the sample container 1072 on the sample rack assembly 107 to different areas of the sample classification storage layer 3. The specific transfer rules of the sample container 1072 will be described later. The empty sample rack 1071, after being transferred, will descend back to the sample transfer layer 2 via the lifting mechanism. Then, the empty sample rack 1071 will continue to be conveyed to the left. After reaching the left side, it will turn forward and be conveyed to the sample outlet area 260. After reaching the position in front of the sample outlet area 260, it will be conveyed onto the second conveyor belt 270. It will then be conveyed from right to left via the second conveyor belt 270 to the sample rack collection device 103. Upon reaching the sample rack collection device 103, the empty sample rack 1071 will be conveyed backward again and collected into the sample rack collection area D1 of the sample rack collection device 103. At this point, the transfer process of the sample rack 1071 is complete.

[0077] The first conveyor belt 210 includes a left conveyor belt 610 and a right conveyor belt 620, with the right conveyor belt 620 disposed on the side of the left conveyor belt 610; the horizontal deflector assembly 220 is disposed on the side of the right conveyor belt 620; the barcode scanning assembly 230 is disposed on the side of the horizontal deflector assembly 220; the stop assembly 240 is disposed on the side of the left conveyor belt 610; the lifting assembly 250 is disposed on the side of the left conveyor belt 610; the sample output area 260 is disposed on the side of the left conveyor belt 610; the second conveyor belt 270 is disposed on the side of the sample output area 260; and the quality control rack buffer area 280 is disposed on the side of the first conveyor belt 210. The left conveyor belt 610 includes one flat belt 611 and five pulleys 612a, 612b, 612c, 612d, and 612e. The flat belt 611 passes through the five pulleys respectively. A motor is installed in wheel 612c, which rotates the wheel 612c, thereby driving the flat belt 611. The right conveyor belt 620 includes one flat belt 621 and ten wheels 622a, 622b, 622c, 622d, 622e, 622f, 622g, 622h, 622j, and 622k. The flat belt 621 passes through each of the ten wheels. A motor is installed in wheel 622a, which rotates the wheel 622a, thereby driving the flat belt 621. The sample rack assembly 107 conveys the sample to the left along the upper surfaces of the flat belts 611 and 621. A space M1, lower than the upper surface of the conveyor belt 611, is provided between the conveyor belts 610 and 620. A space M2, lower than the upper surface of the conveyor belt 621, is located in the middle of the conveyor belt 620. Spaces M1 and M2 are the initial positions of the lifting support 712 on the lifting assembly 250, which will be described later. That is, when the sample rack assembly 107 is running on the first conveyor belt 210, the lifting assembly 250 will not obstruct its normal operation.

[0078] The horizontal guide rail 222 is fixedly mounted above the horizontal guide base plate 221; the slider 223 is slidably mounted on the side of the horizontal guide rail 222; the first rotating wheel 2241 and the second rotating wheel 2242 are rotatably mounted on both sides of the horizontal guide rail 222; the synchronous belt 225 is mounted on the side of the first rotating wheel 2241 and the second rotating wheel 2242; the horizontal guide motor 226 is fixedly mounted on the side of the horizontal guide base plate 221, and the output end of the horizontal guide motor 226 is fixedly connected to the first rotating wheel 2241; the rotating shaft 227 is fixedly mounted on the side of the horizontal guide base plate 221. Above slider 223; the dial plate 228 is rotatably mounted above the rotating shaft 227. The dial plate 228 has a first guide wheel 2281, a first hook 2282, and a second hook 2283. The first guide wheel 2281 is located on the top of the dial plate 228, and the first hook 2282 and the second hook 2283 are located on both sides of the dial plate 228. The guide member 229 is fixedly mounted on the side of the transverse dial base plate 221. The guide member 229 has a guide groove 2291, and the first guide wheel 2281 is located in the guide groove 2291. Slider 223 can move left and right along transverse dial guide rail 222, dial plate 228 can rotate and swing along rotating shaft 227, and the first guide wheel 2281 can slide back and forth in guide groove 2291, thereby enabling the hook to move along the path of guide groove 2291 when the motor is running. Transverse dial assembly 220 is fixedly mounted on the right rear side of the first conveyor belt 210. Figure 9 The position of the transverse deflector assembly 220 in its initial state is in a blocking state, with the second deflector hook 2283 extending above the first conveyor belt 210. When the sample holder assembly 107 is just conveyed onto the first conveyor belt 210 of the sample post-processing device 101, its left end face touches the deflector hook and is therefore precisely blocked near the right end face of the first conveyor belt 210 (this position is defined as J1). Figure 10The posture of the sample rack assembly 107 when the horizontal toggle component 220 toggles is as follows: At this time, the first hook 2282 contacts the right end face of the sample rack assembly 107, pushing the sample rack assembly 107 to move to the left and enter the position of the barcode scanning component 230. Each time it moves, the barcode scanning component 230 will perform a presence or absence detection on the sample container 1072 on the sample rack assembly 107. If a sample container 1072 is detected, the barcode scanning component 230 will scan and read the sample container ID 1074 and send the relevant information to the main computer 106. The specific structure of the barcode scanning component 230 can be referred to the "sample tube barcode scanning component 4" in the utility model patent "Sample Pretreatment and Automatic Transmission Device" with application number CN201821826906. It is fixedly set at a position slightly behind the first conveyor belt 210, with part of its structure located above the first conveyor belt 210, but it does not affect the leftward conveying of the sample rack assembly 107 on the first conveyor belt 210. Once all sample containers 1072 on the sample rack assembly 107 have been inspected and scanned, the horizontal deflector 220 returns to its initial position to the right, awaiting the arrival of the next sample rack assembly 107. The inspected and scanned sample rack assembly 107 will then be conveyed to the left by the first conveyor belt 210.

[0079] The rotary motor 242 is fixedly mounted on the side of the stop base plate 241; the stop plate 243 is fixedly connected to the output end of the rotary motor 242 and located on the side of the rotary motor 242. The stop plate 243 has a groove 2432 and an extension plate 2433. The groove 2432 is located on the side of the stop plate 243 away from the rotary motor 242, and the extension plate 2433 is located on the side of the stop plate 243 close to the rotary motor 242; the position detection sensor 244 is located on the side of the stop base plate 241; and the limiting plate 245 is fixedly mounted on the side of the stop base plate 241. The function of the stop assembly 240 is to stop the sample rack assembly 107 that has been detected and scanned on the first conveyor belt 210 (the stop position is defined as J21), so as to facilitate the subsequent operation of the lifting assembly 250 on the sample rack assembly 107. The main function of the groove 2432 is to ensure that the far end of the stop plate 243 blocks the sample holder assembly 107, so that when the sample holder assembly 107 stops, it is in close contact with the lifting component 250 (described later) and does not tilt away from the lifting component 250 (i.e., in front of the sample post-processing device 101). The extension plate 2433 is used to detect the position of the stop plate 243. Figure 12 The posture of the blocking component 240 when it blocks the sample rack assembly 107. Figure 13 The position of the stop component 240 when releasing the sample rack assembly 107 is the initial position of the stop component 240.

[0080] The left guide plate 2502 and the right guide plate 2503 are fixedly disposed on both sides of the lifting base plate 2501; the rear guide plate 2504 is fixedly disposed on the side of the lifting base plate 2501; the front guide plate 2505 is fixedly disposed on the side of the lifting base plate 2501; the two lifting guide rails 2506 are respectively fixedly disposed on one side of the lifting base plate 2501; the lead screw motor 2507 is disposed on the side of the lifting base plate 2501; the sliding component 710 includes a sliding base plate 711, a lifting support component 712, and a first sensing plate 713. The sliding base plate 711 is disposed between the two lifting guide rails 2506 and threadedly connected to the lead screw of the lead screw motor 2507; the lifting support 712 is fixedly disposed below the sliding base plate 711; the first sensing plate 713 and the second sensing plate 714 are fixedly disposed on both sides of the sliding base plate 711; the clamping plate 716 is slidably disposed on the side of the sliding base plate 711; the second guide wheel 718 is rotatably disposed on the side of the clamping plate 716. The shaft of the lead screw motor 2507 is parallel to the extending direction of the lifting guide rails 2506 to drive the sliding component 710 to lift. A first sensing plate 713 for resetting the lifting component 250 is disposed on the left side of the sliding base plate 711, and a second sensing plate 714 for detecting that the lifting component 250 is in the raised position is disposed on the right side. A tension spring is disposed between the sliding base plate 711 and the clamping plate 716. Figure 16 (Not shown in the image), the clamping plate 716 is pulled backward, causing it to consistently tend to move backward. A second guide wheel 718 is provided on the clamping plate 716. The second guide wheel 718 remains in contact with the rear guide plate 2504 during lifting and lowering, preventing the clamping plate 716 from moving backward. Combined with... Figure 14 and Figure 16As can be seen, when the lifting assembly 250 is operating, the bottom surface of the sample rack assembly 107 is supported above the plane at the end position 712a of the lifting support 712. The left guide plate 2502, right guide plate 2503, front guide plate 2505, and clamping plate 716 form a semi-enclosed space K1, which is the space in which the sample rack assembly 107 operates on the lifting assembly 250. The reason why the left guide plate 2502, right guide plate 2503, and rear guide plate 2504 are set with a structure that is thinner at the bottom and thicker at the top is to make the space K1 also a structure that is larger at the bottom and smaller at the top. For convenience, the position where the sample rack assembly 107 is lifted by the lifting assembly 250 to the sample classification storage layer 3 is defined as J22. It can be seen that the position of J22 is directly above the position of J21. The height difference between the two is the stroke of the lifting assembly 250 lifting the sample rack assembly 107. At position J21, the space K1 is relatively large, allowing the sample holder assembly 107 to easily enter without getting stuck. At position J22, the sample holder assembly 107 is in a state of reliable limiting and minimal positional deviation, ensuring accurate positioning of the sample holder assembly 107. Figure 17 , 18 This refers to the relative positions of the sample rack assembly 107 with the clamping plate 716 and the front guide plate 2505 when the sample rack assembly 107 is in positions J21 and J22, respectively. As the sample rack assembly 107 rises from position J21 to position J22, the distance N between it and the front guide plate 2505 decreases, ensuring reliable limiting and accurate positioning of the sample rack assembly 107 in position J22. Furthermore, due to... Figure 17 It can be seen that the lower edge of the clamping plate 716 is directly above the step position 1076 of the sample holder 1071. This design provides a mechanical limit in the vertical direction for the sample holder assembly 107, ensuring that the sample holder 1071 will not be lifted up when the robotic arm 40 grips the sample container 1072 from the sample holder assembly 107.

[0081] The sample classification and storage layer 3 includes multiple storage mechanisms 31 and a quality control material refrigeration assembly 32; the storage mechanism 31 includes a sample storage tray 311, a retrieval tray 312, and a temporary storage tray 313; the sample storage tray 311 is located below the robotic arm motion layer 4, the retrieval tray 312 is located on the side of the sample storage tray 311, and the temporary storage tray 313 is located on the side of the sample storage tray 311, the temporary storage tray 313 having a channel 3132; the quality control material refrigeration assembly 32 includes a quality control material base plate 321 and a quality control material tray 322. The system comprises a rotating shaft 325, a quality control material tray cover 323, and a quality control material motor 324. The quality control material base plate 321 is disposed on the side of the sample storage tray 311, the quality control material tray 322 is fixedly disposed inside the quality control material base plate 321, the rotating shaft 325 is rotatably disposed on the side of the quality control material base plate 321, the quality control material tray cover 323 is fixedly disposed on the side of the rotating shaft 325, and the quality control material motor 324 is rotatably disposed on the quality control material base plate 321, with the output end of the quality control material motor 324 rotatably connected to the quality control material tray cover 323. Figure 6 The sample classification storage layer 3 includes multiple forward-expandable storage mechanisms 31. Sample storage trays 311 are provided on these storage mechanisms 31. The sample storage trays 311 can be defined as archiving areas 3111 or pending areas 3112 to hold sample containers 1072 whose test results have been archived or whose test results are pending review. Operators can define the location and number of archiving areas 3111 and pending areas 3112 according to sample conditions, operating habits, and other practical considerations. Additionally, the storage mechanism 31 may also be equipped with a retrieval tray 312 and a temporary storage tray 313. In this embodiment, the retrieval tray 312 and the temporary storage tray 313 are located on the same storage mechanism 31. The retrieval tray 312 is located at the front end of the storage mechanism 31 and can be defined as a retrieval area 3121 to hold sample containers 1072 that need to be retrieved promptly. A temporary storage tray 313 is located at the rear end of the storage mechanism 31 and is adjacent to the retrieval tray 312. It can be defined as a buffer area 3131 to store sample containers 1072 that are abnormal (sample rack ID 1073 or sample container ID 1074). The temporary storage tray 313 also has a channel 3132 that allows sample containers 1072 to pass downwards, so that sample containers 1072 requiring disposal can be dropped into the sample recovery layer. During normal instrument operation, these storage mechanisms 31 are all locked inside the instrument.

[0082] Normally, once the first archiving area 3111 is full of sample containers 1072, subsequent sample containers 1072 will be placed in the second archiving area, the third archiving area, and so on, until all archiving areas are full. At this point, the instrument will sound an alarm indicating that the archiving area is full. The operator will then... Figure 4When operating the instrument via the display screen 7, if the archive area 3111, which is already full of sample containers 1072, needs to be popped out, the corresponding storage mechanism 31 will automatically pop forward a certain distance. Then, the operator continues to pull the storage mechanism 31 forward until the tray placed on it is completely outside the instrument. At this point, the operator can manually remove the corresponding tray, replace it with the corresponding empty tray, and then push the storage mechanism 31 back into the instrument and lock it in place.

[0083] Similarly, when the waiting area 3112, the retrieval area 3121, and the buffer area 3131 are full, the instrument will also sound an alarm, indicating that the waiting area 3112, the retrieval area 3121, and the buffer area 3131 are full. At this time, the operator can refer to the situation when the archive area 3111 is full and perform relevant operations on the instrument.

[0084] Of course, if necessary, when the archiving area 3111 / pending review area 3112 / retrieval area 3121 / buffer area 3131 is not full, the operator can also operate the instrument on the display screen 7 to pop up the sample storage tray 311 that needs to be retrieved. If the pop-up area is archive area 3111 or pending area 3112, the robotic arm 40 will place the sample container 1072 that needs to be placed in archive area 3111 or pending area 3112 into the next archive area 3111 or pending area 3112. If the pop-up area is retrieval area 3121 or buffer area 3131, and the robotic arm 40 has a sample container 1072 that needs to be placed in retrieval area 3121 or buffer area 3131, the instrument will alarm and terminate the sorting process. After the operator has finished processing the sample container 1072 in retrieval area 3121 or buffer area 3131, retrieval area 3121 or buffer area 3131 will be pushed back into the instrument and locked (i.e., returned to the initial state). Then, the instrument will place the sample container 1072 into the corresponding area and continue the subsequent sorting process. The function of the quality control material refrigeration component 32 is to refrigerate the quality control materials required by the IVD testing instrument in an environment of 2-8°C. A quality control tray cover 323 is provided above the quality control tray 322, ensuring that the quality control materials are in a closed space with no heat exchange with the outside environment. The quality control tray cover 323 is connected to a quality control motor 324, enabling the cover 323 to automatically open and close around a rotation axis 325, facilitating the placement and removal of quality control materials. A cooling component (not shown in the figure) is provided at the bottom of the quality control tray 322, which is responsible for transferring heat from the closed space containing the quality control materials to the outside. The transferred heat is then transferred to the outside of the instrument via a fan.

[0085] The second Y-axis support 4112 is fixedly disposed between the two first Y-axis supports 4111. The Y-axis drive shaft 412 is rotatably disposed between the two first Y-axis supports 4111. The two first Y-axis pulleys 4131 are slidably disposed at both ends of the Y-axis drive shaft 412. The two second Y-axis pulleys 4132 are respectively rotatably disposed on the sides of the two first Y-axis supports 4111. The two first Y-axis drive belts 4141 are respectively sleeved on the two first Y-axis pulleys 4131 and the two first Y-axis supports 4111. The Y-axis motor mounting plate 415 is fixedly mounted on the side of the second Y-axis support 4112, and the Y-axis motor 416 is fixedly mounted on the Y-axis motor mounting plate 415. The second Y-axis transmission belt 4142 is sleeved on the side of the output shaft of the Y-axis motor 416 and the Y-axis drive shaft 412. Two Y-axis guide rails 417 are respectively fixed above the two first Y-axis supports 4111, and two Y-axis sliding members 418 are respectively slidably mounted on the sides of the two Y-axis guide rails 417. When the Y-axis motor 416 rotates, it can drive the Y-axis sliding members 418 to slide back and forth along the Y-axis guide rails 417.

[0086] The X-axis support 421 is fixedly mounted on the sides of the two Y-axis sliding members 418. The X-axis motor 422 is fixedly mounted on the side of the X-axis support 421. The X-axis pulley 423 is rotatably mounted on the side of the X-axis support 421. The X-axis transmission belt 424 is sleeved on the output shaft of the X-axis motor 422 and the X-axis pulley 423. The X-axis guide rail 425 is fixedly mounted on the side of the X-axis support 421. The X-axis sliding member 426 is slidably mounted on the side of the X-axis guide rail 425, and the X-axis sliding member 426 and the X-axis transmission belt 424 are fixedly connected. When the X-axis motor 422 rotates, it can drive the X-axis sliding member 426 to slide left and right along the X-axis guide rail 425.

[0087] The first Z-axis support 431 is fixedly mounted on the side of the X-axis slider 426. The Z-axis motor 432 is fixedly mounted on the side of the first Z-axis support 431. Two Z-axis pulleys 433 are rotatably mounted on the side of the first Z-axis support 431. The Z-axis guide 434 is fixedly mounted on the side of the first Z-axis support 431. The vertical guide rail 435 is slidably mounted on the side of the Z-axis guide 434. The second Z-axis support 436 is fixedly mounted on the side of the vertical guide rail 435. The Z-axis drive belt 438 is wound around the output shaft of the Z-axis motor 432 and the sides of the two Z-axis pulleys 433, and both ends of the Z-axis drive belt 438 are fixedly mounted on both ends of the second Z-axis support 436. The clamping component 437 is located below the second Z-axis support 436. When the Z-axis motor 432 rotates, it drives the second Z-axis support 436 to move up and down under the guidance of the Z-axis guide 434.

[0088] The driving component 4371 is disposed below the second Z-axis support 436, the clamping component 4372 is disposed below the driving component 4371, the clamping guide 4373 is disposed below the driving component 4371, the telescopic component 4374 is disposed between the clamping guide 4373 and the driving component 4371, the spring structure 4375 is disposed between the telescopic component 4374 and the driving component 4371, the clamping sensor 4376 is disposed on the side of the telescopic component 4374, and the clamping sensor 4377 is disposed on the side of the driving component 4371. The clamping component 437 is used to clamp the sample container 1072. Under the driving control of the driving component 4371, the clamping component 4372 can open and close in the front-back direction, thereby realizing the clamping of the sample container 1072; the telescopic component 4374 includes a spring structure 4375, so that the telescopic component 4374 is always in a downward-extended state. In this way, when the sample container 1072 is gripped, the lower end face of the telescopic component 4374 rests against the container lid 1075 of the sample container 1072, thus limiting the position of the sample container 1072. Additionally, a gripping sensor 4376 is installed on the telescopic component 4374, and a gripping sensor 4377 is installed on the drive component 4371. When the gripper 4372 is not gripping a sample container 1072, the gripping sensor 4376 is located away from the gripping sensor 4377. When the gripper 4372 grips a sample container 1072, the gripping sensor 4376 enters the sensing area of ​​the gripping sensor 4377. This design allows the instrument to know whether a sample container 1072 is gripped on the gripping component 4377. Based on this, the instrument can then perform different actions according to the procedure, ensuring the safe, reliable, and correct sorting and transfer of the sample container 1072. Figure 21-24It can be seen that the gripping component 437 can move along the Y-axis, X-axis and Z-axis under the action of the Y-axis component 41, X-axis component 42 and Z-axis component 43 to realize the sorting and transfer of the sample container 1072.

The two cabinet doors 112 are respectively located on the sides of the frame 111, the multiple casters 113 are respectively located at the bottom of the frame 111, and the machine feet 114 are located at the bottom of the frame 111. The collection bin detection component 117 and the collection bin full-load detection component 118 are located on the sides of the frame 111. The sample collection device 120 is located inside the cabinet assembly 110, such as... Figure 27 The initial position of the sample collection device 120 is shown. During normal operation, the sample collection device 120 is in the retracted state. Casters 113 are provided to facilitate the movement of the entire post-processing system. A foot 114 is also provided at the bottom of the frame 111. After the post-processing system is positioned, the foot 114 extends downwards until it firmly touches the ground, fixing the entire post-processing system in the desired position. An electrical control board (not shown) is also provided at the rear of the cabinet assembly 110 to control the operation of the electrical components of the entire sample collection layer 1. An opening 116 is provided at the top of the cabinet assembly 110. The opening 116 corresponds to the channel 3132 in the sample classification and storage layer 3, allowing discarded sample containers 1072 to fall smoothly into the sample collection device 120 in the sample recovery layer.

The collection bucket 125 is installed on the top of the collection bucket support plate 124. The pop-out door 127 is installed at the front end of the collection bucket support plate 124. The button component 128 is installed on the side of the pop-out door 127. The bucket lid support plate 130 is fixedly installed on the top of the collection bucket support plate 124. The collection bucket lid 129 is installed on the side of the bucket lid support plate 130. A locking component 123 is provided at the front end of the sample base plate 121 to lock the sample collection device 120 and detect whether locking is complete. The collection bucket support plate 124 is installed on the sample guide rail 122 and can move back and forth along the sample guide rail 122. The collection bucket 125 is placed in the middle of the collection bucket support plate 124. Collection bin 125 is a dedicated medical waste collection bin, with an approximately cylindrical structure and an open top. During normal operation, the operator needs to place a collection bag (not shown in the figure) inside the collection bin 125. The collection bag is a dedicated medical waste bag. Sample containers 1072 discarded from sample sorting and storage layer 3 are collected inside the collection bag. A collection bin lid 129 is provided on top of the collection bin 125 to securely fix the collection bag and partially seal the opening of the collection bin 125. A spring assembly (not shown in the figure) is also provided inside the lid support plate 130 to automatically open the collection bin lid 129. Additionally, returning to... Figure 27The cabinet assembly 110 also includes a collection bucket detection component 117 and a collection bucket full-load detection component 118. The collection bucket detection component 117 is located on one side of the sample collection device 120 and is used to detect whether a collection bucket 125 is already on the sample collection device 120. If so, the instrument will operate automatically; otherwise, the instrument will issue an alarm, reminding the operator to accurately place the collection bucket 125 according to the operating procedures. The collection bucket full-load detection component 118 is located near the opening 116 and is used to detect whether the number of waste sample containers 1072 inside the collection bucket 125 has reached a certain amount. If the specified number is reached, the instrument will issue an alarm. When the instrument alarm indicates that the collection bucket 125 is full or the operator needs to clean the waste sample containers 1072 collected inside the collection bucket 125, the operator operates the instrument from the display screen 7 mentioned above, causing the sample collection device 120 to pop forward to a certain position. Then, the operator presses the button component 128. At this time, the collection bucket cover 129 automatically pops up under the action of the spring assembly. The operator removes the collection bag from inside collection bin 125, places a new collection bag inside collection bin 125, closes collection bin lid 129, and pushes sample collection device 120 back into the instrument. This completes one waste sample collection and disposal process. The electrical control layer 5 is the top layer of the entire system and serves as the "brain" of the post-processing system, primarily responsible for power supply control, logic control, and motion control within the system.

[0091] The following describes the process of the post-processing system supplying quality control materials to the testing instruments.

[0092] Back Figure 1 A quality control rack buffer area 280 is also provided in front of the lifting assembly 250.

[0093] First, the quality control rack assembly L will be described. As mentioned earlier, in the fully automated sample processing system, multiple sample containers 1072 are placed on sample racks 1071, forming the sample rack assembly 107 for transport. Similarly, quality control materials are transported in the same way. A quality control material container L2 containing the quality control material is placed on a quality control rack L1, forming the quality control rack assembly L, which operates within the fully automated sample processing system.

[0094] When the sample post-processing device 101 starts operating, after the robotic arm 40 sorts the sample containers 1072 on the sample rack assembly 107, the lifting component 250 lowers the empty sample rack 1071 from position J22 to position J21 on the first conveyor belt 210. At this point, the system will push the sample rack 1071 from position J21 onto the quality control rack buffer area 280. The sample rack 1071 will then be converted into a quality control rack L1, ready for subsequent placement of the quality control container L2.

[0095] When the sample detection device 104 needs to perform quality control calibration, it sends a command to the host computer 106. The host computer 106 then sends a corresponding command to the sample post-processing device 101. At this time, the sample post-processing device 101 executes the command. First, the RFID component 281 located on the right side of the quality control rack buffer area 280 reads the ID of the quality control rack L1 placed on the last side of the quality control rack buffer area 280. Then, the quality control rack L1 is pushed to position J21 and moves to position J22 with the lifting assembly 250. At this time, the quality control material motor 324 of the quality control material refrigeration assembly 32 automatically opens the quality control material tray cover 323. The robotic arm 40 takes out the corresponding quality control material container L2 from the quality control material refrigeration assembly 32 and places it on the quality control rack L1 at position J22. Subsequently, the control material tray cover 323 will automatically close, and the control material container L2 will form a control frame assembly L with the control frame L1, which will be lowered to position J21 by the lifting component 250, and then transferred to the second conveyor belt 270 via the sample dispensing area 260.

[0096] Figure 30 This is a schematic diagram of the route for the quality control rack assembly L from the sample post-processing device 101 to the sample input device 105 (hereinafter referred to as the quality control rack assembly L feeding route schematic diagram). When the quality control rack assembly L reaches the second conveyor belt 270, the second conveyor belt 270 will move from left to right, conveying the quality control rack assembly L to the sample buffer device 102. The sample buffer device 102 continues to convey the quality control rack assembly L to the right, passing through the sample detection device 104 and reaching position J23 in the sample input device 105. The quality control rack assembly L, upon reaching position J23, will then proceed along... Figure 1 The sample rack assembly L moves in the direction of the middle arrow (i.e., the running direction of the sample rack assembly 107) to the corresponding sample detection device 104, allowing the sample detection device 104 to perform quality control calibration. After completing the operation, the quality control rack assembly L will continue to move towards the sample post-processing device 101 along the running direction of the sample rack assembly 107.

[0097] Upon arrival at the sample post-processing device 101, if the control container L2 is not yet used up, the robotic arm 40 will return the control container L2 from the control rack L1 to the control refrigeration assembly 32; if the control container L2 is used up, the robotic arm 40 will drop the control container L2 from the control rack L1 into the sample collection device 120. At this time, the control rack L1, with the control container L2 removed, will return to position J21. If the control rack buffer area 280 is not full, the control rack L1 will be pushed into the control rack buffer area 280; if the control rack buffer area 280 is full, the control rack L1 will be conveyed to the second conveyor belt 270 via the sample dispensing area 260. The second conveyor belt 270 runs from right to left, conveying the control rack L1 to the sample rack collection device 103. The sample rack collection device 103 then pushes the quality control rack L1 back into its sample rack collection area D1.

[0098] At this point, the fully automated sample processing system A will complete the process of automatically transferring the quality control material to the sample detection device 104, and the sample detection device 104 will then automatically complete the quality control calibration operation.

[0099] like Figure 31 As shown in some modified embodiments, the fully automated sample processing system may not connect the sample buffer device 102, but instead connect the sample detection device 104 directly to the sample post-processing device 101. As can be seen from the figure, in this case, a sample injection area 290 is added to the left side of the sample post-processing device 101. The sample post-processing device 101 then becomes the sample post-processing device 1011, and the fully automated sample processing system becomes the fully automated sample processing system 1.

[0100] At this time, the sample rack assembly 107 will be directly conveyed from right to left from the conveyor channel at the front end of the sample detection device 104 to the second conveyor belt 270 of the sample post-processing device 1011. When the sample rack assembly 107 reaches position J24 of the second conveyor belt 270, the sample rack assembly 107 stops conveying to the left and moves backward to the sample loading area 290. Until it is conveyed to the rearmost position of the sample loading area 290, the sample loading RFID component 282 identifies and reads the sample rack ID 1073 and sends it to the host computer 106. Then, the sample rack assembly 107 is pushed onto the first conveyor belt 210. The sample rack assembly 107, upon reaching the first conveyor belt 210, is pushed by the horizontal deflector component 220 and identifies and reads the sample container ID 1074 through the barcode scanning component 230, and sends it to the host computer 106. Then, the post-processing system 1, like the post-processing system, performs various operations on the sample rack assembly 107, such as lifting and lowering, sorting sample containers 1072, and discarding sample containers 1072.

[0101] like Figure 32As shown, in some modified embodiments, the sample post-processing device 101 can be used in conjunction with only the sample buffer device 102 and the sample rack collection device 103 to form a standalone small sample post-processing pipeline A2. In this case, the sample buffer device 102 transforms into a sample input device C1, that is, the sample rack assembly 107 is input from the sample input device C1, and then transferred to the sample post-processing device 101 for sorting, collection, storage, and disposal. Finally, the empty sample rack 1071 is transferred to the sample rack collection device 103. It can be seen that the sample post-processing pipeline A2 is purely for post-processing samples that have been tested on other testing instruments; it does not have sample testing functions itself. Compared with manual processing, this design improves the safety of sample storage and the efficiency of sample processing, while also reducing the risk of aerosol infection for operators.

[0102] In some modified embodiments, the post-processing pipeline A2 can also be used to store samples that have not yet been tested. In this case, the post-processing device 101 will be transformed into the pre-processing system B2, and the post-processing pipeline A2 will be transformed into the pre-processing pipeline A3. This design allows samples in the pre-processing system B2 to be categorized and stored on different sample storage trays 311 according to the different testing items, so that samples with the same testing items can be placed on the same or multiple identical testing instruments for subsequent testing. This allows operators to have a clearer understanding of the specific information of the samples, facilitating subsequent processing.

[0103] In other modified embodiments, the robotic arm motion layer 4 can also be a solution commonly used in automated control equipment such as a six-axis robot or a spider arm, which can also realize the handling and placement of the sample container 1072.

[0104] Of course, the sample testing device 104 connected to the sample post-processing device 101 can be a blood analyzer that includes tests such as complete blood count, coagulation, specific proteins, and biochemistry, or a urine analyzer that includes tests such as dry chemistry, urine sediment, specific proteins, and biochemistry, or an analyzer for other body fluids such as gynecological fluids.

[0105] Secondly, the present invention also provides a sample post-processing system control method, comprising:

[0106] S1 inserts the sample rack assembly into the sample insertion device to read the ID information and transmits the ID information to the main computer;

[0107] The S2 host computer transmits the sample rack assembly to the sample detection device for sample detection based on the ID information.

[0108] The sample assembly processed by the S3 sample detection device will be transmitted to the sample buffer device for identification and reading of the sample rack ID, and the reading result will be sent to the main computer.

[0109] S4 processes the samples using a post-processing device, and the sample rack collection device collects the samples.

[0110] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
