[0031] In the past, the pre-heating system set a circle of pre-heating positions at the edge area of ​​the circular pre-heating plate. In order to set a larger number of pre-heating positions, the diameter of the circular pre-heating plate needs to be set relatively large. In addition, the gripper and the pre-heating plate need to work together (the pre-heating plate rotates horizontally) to transfer the reaction cup to different pre-heating positions of the pre-heating plate. Therefore, the gripper and the pre-heating plate each correspond to a set of driving mechanisms, resulting in this type of pre-heating system occupying a relatively large space.

[0032] To this end, the present application provides a preheating system that occupies a relatively small space and a coagulation analyzer including the preheating system. In order to enable technicians in this technical field to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] The pre-warming system provided in the present application includes a warming mechanism 100 and a first conveying mechanism 200 .

[0034] like Figure 1 As shown, the incubation mechanism 100 includes a pre-heating tray 101. The pre-heating tray 101 is fixed, that is, the pre-heating tray 101 is fixed relative to the installation base of the entire pre-heating system. A plurality of pre-heating positions A are arranged on the tray surface of the pre-heating tray 101.

[0035] like Figure 2 As shown, the first conveying mechanism 200 includes a gripper 214 for grasping a reaction cup, an X-axis conveying assembly capable of driving the gripper 214 to move in a horizontal X-axis, a Y-axis conveying assembly capable of driving the gripper 214 to move in a horizontal Y-axis, and a Z-axis conveying assembly capable of driving the gripper 214 to move in a vertical Z-axis, wherein the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0036] When in use, the pre-heating plate 101 is stationary, and the first conveying mechanism 200 drives the gripper 214 to move in three directions (X direction, Y direction, and Z direction). The gripper 214 grabs the reaction cup containing the sample to be tested and conveys the reaction cup to the pre-heating position A for pre-heating.

[0037] Since the first conveying mechanism 200 can drive the gripper 214 to move along the X, Y and Z directions, the reaction cup can be conveyed to different preheating positions A simply by moving the gripper 214, without the need for the preheating disk 101 to rotate or perform other actions. Therefore, compared with the previous preheating system, the preheating disk 101 driving mechanism is omitted, thereby reducing the space occupied by the preheating system.

[0038] Specifically, the preheating positions A can be set in the entire area of ​​the preheating plate 101, including the central area and the edge area, and are not limited to the edge area of ​​the preheating plate 101. Therefore, compared with the previous preheating system, more preheating positions A can be set under the same surface area of ​​the preheating plate 101, or in other words, the size of the preheating plate 101 required under the same number of preheating positions A is smaller, so the space occupied by the preheating system can be further reduced.

[0039] Preferably, the pre-heating positions A are evenly distributed in a matrix form over the entire area of ​​the pre-heating plate 101, the rows of the matrix may be along the Y direction, and the columns of the matrix may be along the X direction. With this arrangement, the moving path of the gripper 214 is shorter, which is conducive to improving the efficiency of cuvette transfer. For example, Figure 1 In the figure, 36 pre-heating positions A are evenly distributed in a 4×9 matrix over the entire area of ​​the pre-heating disk 101. Figure 1 In the embodiment, the pre-heating plate 101 is a rectangular structure, so that it can match the pre-heating positions A distributed in a matrix form.

[0040] In one embodiment, Figure 1As shown, the incubation mechanism 100 also includes a support 103 supported under the pre-heating tray 101, a cover plate 102 covering the pre-heating tray 101, a connection portion 104 connecting the pre-heating tray 101 and the support 103, a heating circuit board 105 located under the pre-heating tray 101, a temperature sensor 106 for monitoring the heating temperature, an insulating layer (not shown in the figure) arranged between the heating circuit board 105 and the pre-heating tray 101, and a heat preservation layer 107 arranged around the pre-heating tray 101 and under the heating circuit board 105. Specifically, the heat preservation layer 107 can be made of foam, and the cover plate 102 and the connection portion 104 can be made of plastic. An avoidance hole is provided in the area corresponding to the pre-heating position A on the cover plate 102.

[0041] In one embodiment, Figure 2 As shown, the Y-direction transmission assembly includes a Y-direction base 201, a Y-direction driving portion 202 and a Y-direction transmission portion 203 mounted on the Y-direction base 201, and a Y-direction slider 204 connected to the Y-direction transmission portion 203. The Y-direction driving portion 202 drives the Y-direction transmission portion 203 to drive the Y-direction slider 204 to move along the Y-direction.

[0042] The X-direction transmission assembly includes an X-direction base 206, an X-direction driving unit 207 and an X-direction transmission unit 208 mounted on the X-direction base 206, and an X-direction slider 209 connected to the X-direction transmission unit 208. The X-direction driving unit 207 drives the X-direction transmission unit 208 to drive the X-direction slider 209 to move along the X-direction. The X-direction base 206 is fixed relative to the Y-direction slider 204.

[0043] The Z-direction transmission assembly includes a Z-direction base 211, a Z-direction driving unit 212 and a Z-direction transmission unit 213 mounted on the Z-direction base 211. The gripper 214 is fixed relative to the Z-direction transmission unit 213. The Z-direction driving unit 212 drives the Z-direction transmission unit 213 to drive the gripper 214 to move in the Z direction. The Z-direction base 211 is fixed relative to the X-direction slider 209.

[0044] When the Y-direction slider 204 moves in the Y-direction, the entire X-direction conveying assembly, the entire Z-direction conveying assembly, and the gripper 214 all move in the Y-direction. When the X-direction slider 209 moves in the X-direction, the entire Z-direction conveying assembly and the gripper 214 all move in the X-direction. Therefore, the gripper 214 can move in the X-direction, the Y-direction, and the Z-direction.

[0045] In one embodiment, Figure 2 As shown, the Y-direction drive unit 202, the X-direction drive unit 207 and the Z-direction drive unit 212 all use motors, the Y-direction transmission unit 203 and the X-direction transmission unit 208 all use belt transmission structures, and the Z-direction transmission unit 213 uses a gear rack transmission structure. In this way, the transmission efficiency is high and the space occupied is small. Of course, it is not limited to this. For example, the X-direction, Y-direction and Z-direction drive units can also use cylinder structures, the X-direction and Y-direction transmission units can also use chain transmission structures, and the Z-direction transmission unit can also use a screw nut structure.

[0046] In one embodiment, Figure 2 As shown, the Y-direction transmission assembly further includes a Y-direction guide rail 205, which is mounted on the Y-direction base 201, and the Y-direction guide rail 205 extends along the Y-direction. The Y-direction slider 204 is slidably matched with the Y-direction guide rail 205, and the Y-direction slider 204 is guided by the Y-direction guide rail 205 in the moving direction. Similarly, the X-direction transmission assembly may also include an X-direction guide rail 210, which is mounted on the X-direction base 206, and the X-direction guide rail 210 extends along the X-direction. The X-direction slider 209 is slidably matched with the X-direction guide rail 210, and the X-direction slider 210 is guided by the X-direction guide rail 210 in the moving direction. Under the guidance of the X-direction guide rail 210 and the Y-direction guide rail 205, the gripper 214 can reach the target position more accurately and quickly.

[0047] In one embodiment, Figure 2 As shown, the first conveying mechanism 200 also includes a horizontal bottom plate 217, a vertical plate 216 fixed on the horizontal bottom plate 217, and a gantry bracket 215. The vertical plate 216 is arranged roughly along the Y direction, and the two longitudinal support parts 307 of the gantry bracket 215 are close to the vertical plate 216 and are located on the same side of the vertical plate 216 and are spaced apart in the Y direction. The Y-direction base 201 spans across the top of the two longitudinal support parts 307 of the gantry bracket 215. The X-direction base 206 is supported on the Y-direction slider 204 in a cantilevered form. With this design, the first conveying mechanism 200 is compact as a whole, small in size, and occupies little space.

[0048] In one embodiment, Figure 3 As shown, the pre-heating system further includes a second conveying mechanism 300. The second conveying mechanism 300 can convey the reaction cup to a designated position, so that the gripper 214 grabs the reaction cup from the designated position and conveys it to the target pre-heating position A.

[0049] In one embodiment, the second conveying mechanism 300 includes a cup holder 305 for loading a reaction cup, a driving unit 302, a transmission unit 303 and a slider 304. The driving unit 302 drives the transmission unit 303 to drive the slider 304 to move horizontally, and the cup holder 305 is fixed relative to the slider 304. It may also include a base 301 and a support unit 307. The driving unit 302 and the transmission unit 303 are mounted on the base 301, and the support unit 307 provides support for the base 301.

[0050] In one embodiment, the driving part 302 adopts a motor, and the transmission part 303 adopts a belt transmission structure. In this way, the transmission efficiency is high and the space occupied is small. Of course, it is not limited to this. For example, the driving part 302 can also adopt a cylinder structure, and the transmission part 303 can also adopt a chain transmission structure or a screw nut structure.

[0051] In one embodiment, the second conveying mechanism 300 further includes a guide rail 306, which is slidably matched with the slider 304, and the guide rail 306 guides the moving direction of the slider 304. Under the guidance of the guide rail 306, the reaction cup can reach the target position more accurately and quickly.

[0052] The present application also provides a coagulation analyzer, comprising the above-mentioned pre-warming system and a sample adding system.

[0053] During operation, the reaction cup containing the sample to be tested is first transported to the designated position by the second transport mechanism 300, and then transported to the preheating position A of the preheating system by the first transport mechanism 200 to be preheated to a suitable temperature. In addition, different types of reagents are added to the sample to be tested by the sample adding system for reaction according to different detection items.

[0054] The sample loading system includes a sample loading needle assembly 400 and a sample loading needle transport mechanism 500 for driving the sample loading needle assembly 400 to rotate horizontally and move vertically.

[0055] In one embodiment, Figure 4 and Figure 5 As shown, the sample adding needle assembly 400 includes a crossbeam 409, a sample adding needle 401, a needle fixing block 402, a guide column 404, a baffle 403 and an elastic buffer 407. The sample adding needle 401 is fixedly connected to the needle fixing block 402. The sample adding needle 401 is also inserted in the crossbeam 409. The sample adding needle 401 and the needle fixing block 402 can move up and down relative to the crossbeam 409. The lower end of the guide column 404 is fixed to the crossbeam 409, and the upper end of the guide column 404 is fixed to the baffle 403. The elastic buffer 407 is sleeved outside the guide column 404 and is located between the baffle 403 and the needle fixing block 402. When the sample adding needle 401 hits an obstacle and moves upward, the needle fixing block 402 also moves upward, squeezing the elastic buffer 407, which provides buffering. After the collision is eliminated, the sample adding needle 401 and the needle fixing block 402 return to their original position under the elastic force of the elastic buffer 407.

[0056] In one embodiment, Figure 4 and Figure 5 As shown, the sample needle assembly 400 also includes an optical coupling baffle 406 and an optical coupling sensor 405. The optical coupling sensor 405 is connected to the controller, the optical coupling sensor 405 is fixed on the crossbeam 409, and the optical coupling baffle 406 is fixed on the needle fixing block 402. When the sample needle 401 hits an obstacle and moves upward, the optical coupling baffle 406 also moves upward. When the optical coupling baffle 406 moves upward to the sensing area of ​​the optical coupling sensor 405, the optical coupling sensor 405 is triggered. At this time, the controller controls the sample needle conveying mechanism 500 to stop moving to prevent the sample needle 401 from being damaged.

[0057] In one embodiment, Figure 4 and Figure 5 As shown, the sample injection needle assembly 400 also includes a fixed clamp block 408, which is fixed relative to the cross beam 409. A waist-shaped structure 410 is provided on the cross beam 409. The fixed clamp block 408 is fixed at the position of the waist-shaped structure 410, and the fixed position of the fixed clamp block 408 and the cross beam 409 can be adjusted along the length direction of the waist-shaped structure 410.

[0058] In one embodiment, Figure 6 As shown, the sample needle conveying mechanism 500 includes a horizontal driving assembly for driving the sample needle assembly 400 to rotate horizontally and a vertical driving assembly for driving the sample needle assembly 400 to move vertically. The vertical driving assembly includes a vertical driving part 502, a vertical transmission part 504 and a vertical transmission shaft 505. The horizontal driving assembly includes a horizontal driving part 501 and a horizontal transmission part 503. The vertical transmission shaft 505 is connected with an upper connecting part and a lower connecting part, the lower connecting part is connected to the vertical transmission part 504, and the upper connecting part 104 is connected to the horizontal transmission part 503. The vertical transmission part 504 drives the lower connecting part 104 and the vertical transmission shaft 505 to move up and down together. The horizontal transmission part 503 drives the upper connecting part 104 and the vertical transmission shaft 505 to rotate horizontally together. The vertical transmission shaft 505 is connected to the sample needle assembly 400, and can be specifically inserted into the central hole of the fixed clamping block 408 of the sample needle assembly 400 and clamped by the fixed clamping block 408.

[0059] In a specific embodiment, Figure 6 As shown, the vertical drive unit 502 and the horizontal drive unit 501 both use motors, and the vertical transmission unit 504 and the horizontal transmission unit 503 use belt transmission structures, so that the transmission efficiency is high and the space occupied is small. Of course, it is not limited to this. For example, the vertical drive unit 502 and the horizontal drive unit 501 can also use cylinder structures, and the vertical transmission unit 504 and the horizontal transmission unit 503 can also use chain transmission structures.

[0060] The above specific examples are used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
