[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model, and they do not specifically limit the present utility model.

[0032] The centrifugal block transfer device provided by the present utility model can transfer at least two centrifugal blocks at the same time, effectively improving the transfer efficiency of the centrifugal block transfer device for centrifugal blocks, thereby effectively reducing the working time of centrifugal block transfer and improving the sample processing efficiency.

[0033] In a specific embodiment of the present utility model, as Figures 1 to 5 shown, the centrifugal block transfer device includes a machine base 1, at least two groups of transfer assemblies 2 and a centrifugal block fixing assembly 3. At least two groups of transfer assemblies 2 are arranged at intervals on the machine base 1, and each group of transfer assemblies 2 is provided with a group of centrifugal block fixing assemblies 3. The machine base 1 is formed with a loading position 21, a centrifugal position 22 and an unloading position 23. Among them, the loading position 21 can perform the loading operation of the sample centrifugal block, the centrifugal position 22 can perform the centrifugal operation of the sample centrifugal block, and the unloading position 23 can perform the unloading operation of the sample centrifugal block.

[0034] The transfer component 2 is adapted to drive the centrifugal block fixing component 3 to move between the loading position 21 and the unloading position 23, so that the centrifugal block fixing component 3 can be transferred from the loading position 21 to the centrifugal position 22, or from the centrifugal position 22 to the unloading position 23, or from the unloading position 23 to the loading position 21. The centrifugal block fixing component 3 includes at least two centrifugal block fixing bases 31, and the at least two centrifugal block fixing bases 31 are arranged at intervals on the transfer component 2, and the centrifugal block fixing bases 31 are used for installing centrifugal blocks.

[0035] In the centrifugal block transfer device provided by the present utility model, at least two centrifugal block fixing bases 31 are arranged at intervals on the transfer component 2, and at least two sets of transfer components 2 drive the centrifugal block fixing component 3 to be transferred between the loading position 21, the centrifugal position 22 and the unloading position 23, so that during the movement of the centrifugal block transfer device between the loading position 21 and the unloading position 23, at least two centrifugal blocks can be transferred simultaneously, effectively improving the transfer efficiency of the centrifugal block transfer device for centrifugal blocks, thereby effectively reducing the working time of centrifugal block transfer and improving the sample processing efficiency.

[0036] Specifically, as Figure 1 shown, the transfer component 2 is preferably two sets, and the two sets of transfer components 2 are arranged side by side on the machine base 1; four centrifugal block fixing bases 31 are arranged and installed on each set of transfer components 2, so that one set of transfer components 2 can transfer four centrifugal blocks simultaneously. Therefore, in this embodiment, when the two sets of transfer components 2 operate alternately, the centrifugal block transfer device can transfer four centrifugal blocks simultaneously; when the two sets of transfer components 2 operate simultaneously, the centrifugal block transfer device can transfer eight centrifugal blocks simultaneously; and thus, by transferring multiple centrifugal blocks simultaneously, the transfer efficiency of the centrifugal block transfer process in the sample pretreatment system is effectively improved.

[0037] It should be noted here that the centrifugal position 22 is arranged between the loading position 21 and the unloading position 23, the distance from the centrifugal position 22 to the loading position 21 is L1, and the transfer time from the loading position 21 to the centrifugal position 22 is T1; the distance from the centrifugal position 22 to the unloading position 23 is L2, and the transfer time from the centrifugal position 22 to the unloading position 23 is T2. L1 is preferably equal to L2 to ensure that when the moving speed of the transfer component 2 is the same, T1 is equal to T2, so as to facilitate the control of the transfer time of the transfer component 2.

[0038] Among them, any two adjacent transfer components 2 move linearly between the loading position 21 and the unloading position 23, and any two adjacent transfer components 2 move in a staggered manner. Specifically, for the convenience of description, any two adjacent transfer components 2 are respectively marked as the first transfer component and the second transfer component here. In two adjacent transfer components 2, when the first transfer component finishes loading the sample at the loading position 21, the first transfer component transfers the loaded sample to the centrifugation position 22 so that the sample can be centrifuged at the centrifugation position 22, while the second transfer component is not operating. When the sample finishes centrifugation, the first transfer component transfers the sample from the centrifugation position 22 to the unloading position 23 to facilitate taking out the centrifuged sample from the centrifuge block fixing base 31.

[0039] When the first transfer component transfers from the centrifugation position 22 to the unloading position 23, the second transfer component synchronously loads the sample; when the first transfer component unloads the sample, the second transfer component carries another batch of samples and moves from the loading position 21 to the centrifugation position 22 so that another batch of samples can be centrifuged at the centrifugation position 22; when the first transfer component transfers from the unloading position 23 to the loading position 22, the second transfer component synchronously moves from the centrifugation position 22 to the unloading position, so that the two transfer components 2 move in a staggered manner.

[0040] By moving the two transfer components 2 in a staggered manner, while unloading a batch of samples in the first transfer component, the second transfer component is used to carry another batch of samples and transfer them to the centrifugation position 22 for centrifugation, so that an interleaved transfer is formed between the two transfer components, enabling the unloading of one batch of samples and the centrifugation of another batch of samples to be carried out synchronously, effectively increasing the sample centrifugation throughput and further improving the sample processing efficiency.

[0041] In addition, when one of the transfer components 2 fails and cannot operate, the other transfer component 2 can be used to continue transferring the samples, thus ensuring the continuity of sample transfer.

[0042] It should be noted here that when the sample is centrifuged at the centrifugation position 22, the entire set of centrifuge blocks can be transferred to the centrifuge by the centrifuge block transfer manipulator for sample centrifugation; and after the sample centrifugation is completed, the entire set of centrifuge blocks can be taken out of the centrifuge by the same centrifuge block transfer manipulator and placed at the centrifugation position 22, so that the transfer component 2 can transfer the centrifuged sample to the unloading position 23, facilitating the subsequent processes of sample processing.

[0043] Specifically, as Figure 2 and Figure 3As shown in the figure, the transfer component 2 includes a driving member 24, a transmission group 25, and a connecting plate 26. The driving member 24 is arranged on the machine base 1. The driving shaft of the driving member 24 is rotationally connected to the transmission group 25. The transmission group 25 is adapted to move from the loading position 21 to the unloading position 23, or from the unloading position 23 to the loading position 21. The connecting plate 26 is arranged on the transmission group 25. The centrifugal block fixing base 31 is connected to the connecting plate 26, so as to drive the transmission group 25 to move between the loading position 21 and the unloading position 23 through the driving member 24, drive the connecting plate 26 to move, thereby realizing the movement of the centrifugal block fixing base 31 between the loading position 21 and the unloading position 23, and completing the transfer of the centrifugal block.

[0044] Among them, the driving member 24 is preferably a driving motor. The transmission group 25 can be a pulley group, which includes a main transmission pulley 251, a driven transmission pulley 252, and a transmission belt 253. The main transmission pulley 251 is connected to the driving shaft of the driving motor. The main transmission pulley 251, the driven transmission pulley 252, and the transmission belt 253 are cooperatively connected. An installation block is arranged on the upper part of the transmission belt 253. The installation block is a square structure. The connecting plate 26 is connected to the installation block by bolts, so that when the transmission belt 253 runs, it can drive the connecting plate 26 to move, thereby driving the centrifugal block on the centrifugal block fixing base 31 to move between the loading position 21 and the unloading position 23.

[0045] Of course, the transmission group 25 is not limited to the pulley group, and can also be a gear-rack meshing transmission. The gear is connected to the driving shaft of the driving motor, and the connecting plate 26 is connected to the rack, and the centrifugal block fixing base 31 is driven to move through the gear-rack transmission. The transmission group 25 can also be a lead screw module transmission. At this time, the driving motor is the motor of the lead screw module, and the connecting plate 26 is connected to the slider of the lead screw module, so as to drive the slider to move through the lead screw and drive the centrifugal block fixing base 31 to move.

[0046] Furthermore, to improve the stability of the movement of the centrifugal block fixing base 31 between the loading position 21 and the unloading position 23, as Figure 2 and Figure 3 shown, the transfer component 2 further includes two linear slide rails 27. The linear slide rails 27 are arranged on the machine base 1, and the two linear slide rails 27 are respectively located on both sides of the transmission group 25. The connecting plate 26 is slidably connected to the linear slide rails 27 through sliders, so as to utilize the characteristic of high running accuracy of the linear slide rails 27, so that the connecting plate 26 and the centrifugal block fixing base 31 above can maintain an accurate position and direction during the movement, and the balance of the connecting plate 26 and the centrifugal block fixing base 31 above it is maintained through the two linear slide rails 27 during the movement, reducing vibration or other movement instability problems during the movement of the centrifugal block fixing base 31, thereby improving the movement stability of the centrifugal block fixing base 31.

[0047] In this embodiment, as Figure 2 and Figure 3As shown in the figure, a plurality of position detectors 28 are arranged at intervals on the machine base 1. The plurality of position detectors 28 are all located between the centrifugal block fixing base 31 and the machine base 1. One of the position detectors 28 is installed at the loading position 21, another position detector 28 is installed at the unloading position 23, and the remaining position detectors 28 are installed at the centrifugal position 22. By using the position detectors 28 to monitor the movement position of the centrifugal block fixing base 31 in real time, the positioning accuracy of the transfer between the loading position 21, the centrifugal position 22 and the unloading position 23 is increased.

[0048] Preferably, the position detector 28 is an infrared sensor.

[0049] Specifically, during the process of the adjacent two transfer assemblies 2 transferring the centrifugal blocks, when the first transfer assembly moves from the loading position 21 to the centrifugal position 22, if the infrared sensor at the loading position 21 detects that the centrifugal block fixing base 31 leaves the loading position 21, the infrared sensor at the loading position 21 emits a signal, causing the transfer manipulator to move to the centrifugal position 22 of the first transfer assembly, so as to reduce the time consumed between transfer and centrifugation.

[0050] If the infrared sensor at the centrifugal position 22 detects that the centrifugal block fixing base 31 reaches the centrifugal position 22, the infrared sensor at the centrifugal position 22 emits a signal to cause the transfer manipulator to perform the transfer work.

[0051] If the infrared sensor at the unloading position 23 of the first transfer assembly detects that the centrifugal block fixing base 31 reaches the unloading position 23, the infrared sensor at the unloading position 23 in the first transfer assembly emits a signal, causing the second transfer assembly to drive another batch of centrifugal samples to move from the loading position 21 to the centrifugal position 22, so as to realize the synchronous unloading of one batch of samples and centrifugation of another batch of samples, and improve the sample processing efficiency.

[0052] In the embodiment of the present utility model, as Figure 1 and Figure 4 shown, an installation groove 311 is formed on the side of the centrifugal block fixing base 31 facing away from the transfer assembly 2. The centrifugal block is installed in the installation groove 311, and the centrifugal block and the installation groove 311 are in interference fit. The centrifugal block is used to accommodate the centrifugal samples, so as to form a tight fit between the centrifugal block and the installation groove 311. While facilitating the installation of the centrifugal block on the centrifugal block fixing base 31, it effectively prevents the centrifugal block from loosening during the transfer process, resulting in leakage of the samples in the centrifugal block, thereby ensuring the integrity of the samples.

[0053] Among them, a plurality of test tube holes are formed on the upper side of the centrifugal block. After the centrifugal samples are loaded into the test tubes, the test tubes are inserted into the test tube holes to complete the accommodation of the centrifugal samples on the centrifugal block.

[0054] Further, when the transfer assembly 2 moves to the centrifugation position 22, the manipulator moves the entire centrifugation block into the centrifuge for centrifugation. To facilitate the control of the transfer process of the transfer assembly 2, as Figure 1 and Figure 4 shown, a centrifugation block in-position detection member 312 is provided in the installation groove 311 to use the centrifugation block in-position detection member 312 to detect whether there is a centrifugation block on the centrifugation block fixed base 31, and to determine whether the centrifugation block has completed centrifugation, so as to facilitate controlling the transfer assembly 2 to move from the centrifugation position 22 to the unloading position 23.

[0055] Specifically, the centrifugation block in-position detection member 312 can be a photoelectric sensor. When the transfer assembly 2 moves to the centrifugation position 22 and transfers the centrifugation block into the centrifuge for centrifugation, the photoelectric sensor can detect that the centrifugation block leaves the centrifugation block fixed base 31. And when the centrifugation block is placed back on the centrifugation block fixed base 31 after centrifugation, the photoelectric sensor detects the centrifugation block again. At this time, the photoelectric sensor emits a signal to cause the transfer assembly 2 to move from the centrifugation position 22 to the unloading position 23, thereby realizing the movement control of the transfer assembly 2.

[0056] In the embodiment of the present utility model, after the centrifugation block is unloaded, the centrifugation sample above the centrifugation block needs to be completely taken out from the centrifugation block. To facilitate confirming whether the centrifugation sample is completely emptied from the centrifugation block, as Figure 2 and Figure 3 shown, the machine base 1 is provided with a barcode detection sensor 11, and the barcode detection sensor 11 is used to detect the centrifugation sample barcode on the centrifugation block. When the transfer assembly 2 drives the centrifugation block fixed base 31 to move from the unloading position 23 to the loading position 21, the centrifugation block fixed base 31 passes by the barcode detection sensor 11. If the barcode detection sensor 11 recognizes that there is an abnormal sample barcode above the centrifugation block at this time, the barcode detection sensor 11 can emit a signal, so that the transfer assembly 2 can move back to the unloading position 23 again to unload the sample that has not been unloaded from the centrifugation block, thereby effectively ensuring the timeliness of subsequent sample inspection.

[0057] In the embodiment of the present utility model, as Figure 1 and Figure 5 shown, the centrifugation block transfer device further includes a bracket 41 and a plurality of limit baffles 42. The bracket 41 is fixed to the unloading position 23, the plurality of limit baffles 42 are installed on the bracket 41 at intervals, the limit baffles 42 extend along a direction perpendicular to the moving direction of the transfer assembly 2, the centrifugation block fixed base 31 is located between the limit baffles 42 and the machine base 1, and the distance between any two adjacent limit baffles 42 is less than or equal to the width of the centrifugation block.

[0058] It can be understood that since the centrifugal block fixing base 31 is located between the limit baffle 42 and the machine base 1, and the distance between adjacent limit baffles 42 is less than or equal to the width of the centrifugal block, when the centrifugal block fixing base 31 moves to the unloading position 23 for sample unloading, the centrifugal block can be limited between the limit baffle 42 and the machine base 1 by the limit baffle 42, avoiding the centrifugal block detaching from the centrifugal block fixing base 31 during unloading, and effectively improving the unloading safety of the sample.

[0059] Among them, as Figure 5 shown, the bracket 41 includes a fixed support 411 and a plurality of support rods 412. The first ends of the plurality of support rods 412 are vertically and spaced apart at the unloading position 23, the fixed support 411 is installed at the second ends of the support rods 412, the limit baffle 42 is installed on the fixed support 411, and the height of the support rods 412 is greater than the height of the centrifugal block and the centrifugal block fixing base 31 to ensure that the limit baffle 42 is located above the centrifugal block and ensure the limiting effect of the limit baffle 42 on the centrifugal block.

[0060] It should be noted here that the first ends of the support rods 412 and the unloading position 23 of the machine base 1 are detachably connected by bolts, the fixed support 411 and the second ends of the support rods 412 are detachably connected by bolts, and the limit baffle 42 and the fixed support 411 are detachably connected.

[0061] Furthermore, the support rods 412 can be telescopic rods. When different specifications of centrifugal blocks are fixed on the centrifugal block fixing base 31, the height of the support rods 412 can be adjusted to adjust the height of the limit baffle 42 and the fixed support 411, so that the limit baffle 42 can adapt to the heights of different specifications of centrifugal blocks, ensuring the limiting effect of the limit baffle 42 while avoiding the limit baffle 42 occupying too much space and improving the space utilization rate of the limit baffle 42.

[0062] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
