[0031] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0032] Referring to Figure 1 As shown in the utility model embodiment provides a kind of tray type automatic identification device 1000, including bottom plate 100 and detection assembly 200. Bottom plate 100 is horizontally arranged, and bottom plate 100 is suitable for being connected with any one in multiple trays 600 of different types. The following is illustrated by example, inFigure 1 and Figure 3 In order to accommodate test tube racks 610 from different manufacturers, the two trays 600 have different types and structures. Figure 1 The tray 600 has multiple square slots for placing test tube racks 610, which can hold multiple rows of test tubes. Figure 3 The tray 600 has multiple slots for placing test tube racks 610, which can only hold a single row of test tubes. Figure 1 The tray 600 and Figure 3 Each of the trays 600 can be individually attached to the base plate 100. The test tube rack 610 is used to hold samples, which can be blood.

[0033] Reference Figure 1 and Figure 2 As shown, the detection component 200 is used to detect the type of the tray 600 connected to the base plate 100. The detection component 200 includes multiple sensors 210 and multiple first triggers 220. The multiple sensors 210 are fixedly connected to the base plate 100, and the multiple sensors 210 are paired with the multiple first triggers 220 one by one. The multiple first triggers 220 are connected to multiple trays 600 of different types. For multiple trays 600 of different types, the positions of the first triggers 220 connected to the trays 600 are different, so that they can be paired with different sensors 210.

[0034] In some embodiments, the number of sensors 210 can be equal to the number of types of trays 600. For example, arranging ten sensors 210 can detect ten types of trays 600. Each tray 600 is equipped with only one first trigger 220. The type of tray 600 can be determined by which sensor 210 is triggered by the first trigger 220. See reference. Figure 4 and Figure 5 As shown, in some other embodiments, the number of types of trays 600 can be greater than the number of sensors 210. For example, the number of types of trays 600 is twice the number of sensors 210. Each tray 600 is provided with two first triggers 220, and the two first triggers 220 correspond to the two sensors 210 on the trigger base plate 100. By arranging and combining them, it is still possible to detect ten types of trays 600.

[0035] During use, the tray 600 is connected to the base plate 100. The first trigger 220 on the tray 600 will trigger the corresponding paired sensor 210 on the base plate 100. Since multiple sensors 210 on the base plate 100 correspond to multiple types of trays 600, the type of the tray 600 connected to the base plate 100 can be determined based on the triggered sensor 210. This enables automatic identification of the type of tray 600 on the base plate 100. Knowing the type of the tray 600 also reveals the type of the test tube rack 610 placed on it, ensuring that subsequent sample pretreatment procedures can proceed normally. Alternatively, each sensor 210 identifies the type of tray 600; by determining which sensor 210 is triggered by the first trigger 220, the type of tray 600 can be determined.

[0036] In some embodiments, the sensor 210 can be a microswitch 410, a photoelectric sensor, or other components, and the first trigger 220 can be a trigger block or a light-shielding sheet. In some embodiments, the sensor 210 is a Hall effect sensor plate, which is fixedly connected to the top of the tray 600, and the first trigger 220 is a sensing magnet, which is fixedly connected to the bottom of the tray 600. The advantage of using a Hall effect sensor plate is that the first trigger 220 will not have a protruding feature on the bottom of the tray 600 because the thickness of the sensing magnet is small and it occupies less space, allowing the tray 600 to be placed flat on the base plate 100. It should be noted that when the first trigger 220 is a trigger block or a light-shielding sheet, a protruding feature will be formed under the tray 600, requiring additional auxiliary parts to place the tray 600 flat on the base plate 100.

[0037] Reference Figure 2 and Figure 6 As shown, in some embodiments, the base plate 100 is provided with a pull-out assembly 300. The pull-out assembly 300 includes a slide rail 310, a slider 320, and a pull-out plate 330. The slide rail 310 is fixedly connected to the base plate 100, the slider 320 is fixedly connected to the slide rail 310, and the pull-out plate 330 is slidably connected to the slider 320. The pull-out plate 330 is used to support the tray 600. The pull-out plate 330 has a first position. When the tray 600 is connected to the base plate 100 and the pull-out plate 330 is in the first position, the first trigger 220 of the tray 600 triggers the corresponding paired sensor 210 on the base plate 100, that is, the pull-out plate 330 is pulled out into place. It can be understood that... Figure 1 and Figure 3 The pull-out panel 330 is always in the first position.

[0038] In some embodiments, the plurality of sensors 210 are arranged in a straight line direction perpendicular to the sliding direction of the pull plate 330. This arrangement can avoid the first trigger 220 triggering other sensors 210 during the sliding of the pull plate 330. Since the arrangement direction of the sensors 210 is perpendicular to the sliding direction of the pull plate 330, when the pull plate 330 is pushed to the first position, only one sensor 210 will be passed by the first trigger 220, ensuring that the detection result will not be incorrect due to the first trigger 220 triggering other sensors 210. Specifically, referring to Figure 5 , the plurality of sensors 210 are arranged in a left-right direction. Referring to Figure 2 , the sliding direction of the pull plate 330 is a front-back direction. When the pull plate 330 is pushed forward, the first trigger 220 on the tray 600 is aligned with the sensor 210 on the bottom plate 100. When the pull plate 330 is pulled backward, the first trigger 220 is disengaged from the sensor 210.

[0039] Referring to Figure 5 , the sensor 210 is fixedly connected to the bottom plate 100 through the fixing block 230. The fixing block 230 is located between the sensor 210 and the bottom plate 100, and can lift the position of the sensor 210, so that the sensor 210 is closer to the upper tray 600, and the first trigger 220 at the bottom of the tray 600 is closer to the sensor 210, ensuring good contact and stable detection of the type of the tray 600.

[0040] Referring to Figure 6 , in some embodiments, a position sensing assembly 400 is arranged between the bottom plate 100 and the pull plate 330. The position sensing assembly 400 is used to detect whether the pull plate 330 is in the first position. In some embodiments, the position sensing assembly 400 includes a micro switch 410 and a second trigger 420. The micro switch 410 is fixedly connected to the bottom plate 100, and the second trigger 420 is fixedly connected to the pull plate 330. When the pull plate 330 is in the first position, the second trigger 420 triggers the micro switch 410. The type detected by the detection sensor 210 can be controlled after the position sensing assembly 400 determines that the pull plate 330 is in the first position, ensuring the accuracy of the detection result.

[0041] In other embodiments, the position sensing assembly 400 can also be a Hall sensor or a photoelectric sensor.

[0042] Referring to Figure 6As shown in the drawings, in some embodiments, the bottom plate 100 is provided with a first magnetic suction member 110, and the pull-out plate 330 is provided with a second magnetic suction member 332. When the pull-out plate 330 is in the first position, the first magnetic suction member 110 and the second magnetic suction member 332 are magnetically connected, so that the pull-out plate 330 can be kept in the first position. During the process of detecting the type of the tray 600, the first trigger member 220 of the tray 600 and the inductor 210 of the bottom plate 100 are kept in alignment, so that the type of the tray 600 can be accurately identified. In some embodiments, the first magnetic suction member 110 is made of a magnetic material, and the second magnetic suction member 332 is a magnet. The magnetic attraction force is mainly provided by the second magnetic suction member 332. The bottom plate 100 is fixedly connected with a mounting block 335. The mounting block 335 is provided with a mounting groove, and the second magnetic suction member 332 is installed in the mounting groove, so as to fix the second magnetic suction member 332.

[0043] Referring to Figure 6 As shown in the drawings, in some embodiments, the pull-out plate 330 is provided with a notch 331 on one side along the sliding direction of the pull-out plate 330. The notch 331 is used to avoid the detection assembly 200. When the pull-out plate 330 is in the first position, the detection assembly 200 is located in the notch 331.

[0044] Referring to Figure 6 As shown in the drawings, in some embodiments, the pull-out plate 330 is provided with a pull-out handle 334 on the other side along the sliding direction of the pull-out plate 330. The pull-out handle 334 can be a groove or a solid handle structure, which can facilitate the operation of pulling out the pull-out plate 330.

[0045] Referring to Figure 2 As shown in the drawings, in some embodiments, the top of the pull-out plate 330 is provided with a positioning pin 500, and the bottom of the tray 600 is provided with a positioning hole 620. When the tray 600 is placed on the pull-out plate 330, the positioning pin 500 and the positioning hole 620 are positioned and matched, so that during the process of pulling out the pull-out plate 330, the tray 600 will not move relative to the pull-out plate 330. In other embodiments, a positioning groove can also be arranged on the pull-out plate 330, and the tray 600 is placed in the positioning groove to realize the positioning and matching of the tray 600 and the pull-out plate 330.
