[0035] Reference Figures 1 to 4 The embodiment of the utility model provides a test tube push plate loading assembly, including a loading box 100, a conveying assembly 200 and a sensor assembly 300, such as Figure 1 As shown, the interior of the loading box 100 is a accommodating cavity that can accommodate multiple test tubes. A discharge port 101 is provided at the upper end of the loading box 100, and a feed hopper 110 is provided on one side of the loading box 100 to add test tubes. The feed hopper 110 is connected to the side of the accommodating cavity, and test tubes can be replenished when the test tube push plate loading assembly is working without stopping the machine.

[0036] The conveying assembly 200 is connected to the loading box 100, and the upper end of the conveying assembly 200 extends to the discharge port 101. The conveying assembly 200 includes a driving member 210, a back plate mechanism 220, a plurality of fixed plates 230, a plurality of movable push plates 240 and a linear guide rail 250, wherein the fixed plates 230 and the movable push plates 240 can be selected in two groups, three groups or other quantities, and three groups are taken as an example for explanation below. The three fixed plates 230 are arranged vertically and spaced apart, the three movable push plates 240 are arranged vertically and spaced apart, the three fixed plates 230 and the three movable push plates 240 are alternately arranged horizontally, each fixed plate 230 cooperates with a movable push plate 240, the three movable push plates rise synchronously, the lowest movable push plate 240 pushes the test tube upward, the test tube slides or rolls on the side of the lowest fixed plate 230, and at the highest point of the rise, the test tube is sent to the upper end of the middle fixed plate 230, and then the three movable push plates descend synchronously, at the lowest point, the test tube rolls to the upper end of the middle movable push plate 240, and the middle movable push plate 240 pushes the test tube upward, through the continuous lifting action of the three movable push plates 240, the test tube is pushed upward step by step, and finally the continuous loading of the test tube is realized.

[0037] Reference Figure 3 The sensor assembly 300 includes a first sensor 310 and a second sensor 320. The first sensor 310 is arranged at the lower end of the bottom fixed plate 230, and the second sensor 320 is arranged at the lower end of the middle (second lower) fixed plate 230. The first sensor 310 can be used to detect whether there is a test tube on the upper end of the bottom movable push plate 240, and the second sensor 320 can be used to detect whether there is a test tube on the upper end of the middle movable push plate 240. When there is a test tube on the bottom movable push plate 240, but there is no test tube on the middle movable push plate 240, the control driving member 210 is started to continue to push the test tube upward. When the second sensor 320 detects the test tube, the control driving member 210 stops and waits for instructions before continuing to load the material, which can improve the loading efficiency, so that there are always test tubes waiting for loading on the middle movable push plate 240, avoiding the need to transport the test tube from the bottom when the test tube is needed, reducing time consumption and improving efficiency.

[0038] It is understandable that the sensor assembly 300 may also include a third sensor, which is arranged at the lower end of the top fixed plate 230. Referring to the above principle, when the machine is stopped and waiting, the sensor assembly 300 feedbacks information so that there are always test tubes waiting to be loaded on the top movable push plate 240, avoiding the need to transport test tubes from the bottom when test tubes are needed, thus reducing time consumption and further improving efficiency. Correspondingly, four movable push plates 240 can be equipped with four sensors, and so on.

[0039] Reference Figures 2 to 4The conveying assembly 200 further includes a plurality of stirring plates 260, which are connected to the lower end of the lowest movable push plate 240. The stirring plates 260 are located on the side of the movable push plate 240 away from the fixed plate 230. The stirring plates 260 are L-shaped, and a gap is formed between the stirring plates 260 and the movable push plate 240. The upper end of the stirring plates 260 is set as an inclined surface. The stirring plates 260 move with the movable push plate 240, and can stir the test tubes stacked in the accommodating chamber to prevent the test tubes from getting stuck. The inclined surface at the upper end can push the test tubes to move toward the movable push plate 240, which helps the movable push plate 240 to push the test tubes upward.

[0040] The back plate mechanism 220 is slidably connected to the linear guide rail 250. The back plate mechanism 220 can be used as a slider, or a separate slider 251 can be provided. The back plate mechanism 220 is fixed on the slider 251. Considering the distribution position and large volume of the three movable push plates 240, a linear guide rail 250 with a larger width and two sliders 251 are used. The two sliders 251 are fixedly connected to the two ends of the back plate mechanism 220. A first connecting block 221, a second connecting block 222 and a third connecting block 223 are provided on the back plate mechanism 220 to install the three movable push plates 240. The first connecting block 221, the second connecting block 222 and the third connecting block 223 are distributed at intervals in the vertical direction and have different thicknesses, so that the three movable push plates 240 can be accurately positioned in the vertical and horizontal directions after assembly, thereby improving the assembly efficiency. The driving member 210 is used to drive the back plate mechanism 220 to move along the linear guide rail 250, thereby driving the three movable push plates 240 to rise and fall.

[0041] When the test tube push plate loading assembly is in operation, a large number of test tubes are accumulated in the loading box 100, and the driving member 210 of the conveying assembly 200 drives the back plate mechanism 220 to move along the linear guide rail 250, and the back plate mechanism 220 drives the three movable push plates 240 to rise and fall, and the movable push plates 240 push the test tubes to slide or roll on the side of the fixed plate 230, and the three movable push plates 240 relay to realize the automatic loading of the test tubes. Since the relative positions of the three fixed plates 230 and the three movable push plates 240 must be accurate to realize the loading, the back plate mechanism 220 is set, and the back plate mechanism 220 has a first connecting block 221, a second connecting block 222 and a third connecting block 223 to install the three movable push plates 240, accurately define the positions of the three movable push plates 240, accurately match the three fixed plates 230, simplify the assembly process, improve production efficiency, and facilitate later maintenance.

[0042] Reference Figure 4In some embodiments of the first aspect of the utility model, the backplane mechanism 220 includes an adapter plate 224, and the first connecting block 221, the second connecting block 222 and the third connecting block 223 are installed on the adapter plate 224 by fasteners. The first groove, the second groove and the third groove are provided on the adapter plate 224 to position the first connecting block 221, the second connecting block 222 and the third connecting block 223, which is convenient for installation and positioning, and helps to improve the positioning accuracy of the three movable push plates 240.

[0043] Reference Figure 4 The driving member 210 includes a motor 211, a belt 212, a first pulley 213 and a second pulley 214. The first pulley 213 and the second pulley 214 are distributed at both ends of the linear guide 250. The belt 212 is connected to the first pulley 213 and the second pulley 214. The first pulley 213 is fixed to the output shaft of the motor 211. The adapter plate 224 is provided with a belt fixing seat 225. The belt fixing seat 225 is fixedly connected to the belt 212. A receiving groove can be provided on the belt fixing seat 225. The belt 212 is loaded into the receiving groove, and the belt 212 is clamped by a pressure plate. The motor 211 drives the first pulley 213 to rotate, thereby driving the belt 212 to move, the belt 212 drives the belt fixing seat 225 and the adapter plate 224 to move, and the adapter plate 224 drives the three movable push plates 240 to rise. When the movable push plates 240 rise to the highest point, the motor 211 reverses and drives the three movable push plates 240 to descend. The above actions are repeated to realize the cyclic lifting and lowering of the three movable push plates 240.

[0044] Reference Figures 2 to 4 In some embodiments of the first aspect of the utility model, the upper end of the lowest movable push plate 240 is connected to a ramp component 330, and the upper end of the ramp component 330 is provided with an inclined surface, such as Figure 1 As shown, sometimes the test tube will be placed on the upper end of the lowest fixed plate 230. Since the end surface of the test tube cap can abut the upper end of the fixed plate 230, the test tube will stop at the upper end of the lowest fixed plate 230. When the movable push plate 240 rises, the inclined surface of the ramp assembly 330 can push the test tube located at the upper end of the fixed plate 230, so that the test tube enters the pushing range of the middle movable push plate 240 to prevent the test tube from getting stuck. Of course, the upper ends of the three movable push plates 240 can be connected to the ramp assembly 330, or only the upper ends of two of the movable push plates 240 can be connected to the ramp assembly 330, which can be determined according to actual use requirements.

[0045] It can be understood that the ramp assembly 330 includes three cross bars and two connecting pieces that are staggered together. A mounting hole is provided at the upper end of the movable push plate 240. The connecting piece and / or the cross bar are installed in the mounting hole through fasteners. The fasteners can be bolts, or other structural forms such as pins and rivets.

[0046] Reference Figures 2 to 4 In some embodiments of the first aspect of the utility model, roller assemblies 340 are connected to both sides of the upper end of the movable push plate 240, and the roller assembly 340 is provided with a rolling wheel 341, and the rolling wheel 341 abuts against the fixed plate 230. The rolling wheel 341 is used as a support to limit the distance between the movable push plate 240 and the fixed plate 230, reduce the deformation of the movable push plate 240, and prevent the movable push plate 240 from contacting with the fixed plate 230 to generate friction resistance, which is conducive to the accurate movement direction and smooth movement of the movable push plate 240. Figure 5 and Figure 6 As shown, the roller assembly 340 includes a bracket 342 and a rotating shaft 343. The bracket 342 is provided with a mounting groove 344. Both ends of the rotating shaft 343 are inserted into the mounting groove 344. The mounting groove 344 is closed by a shaft pressure plate 345 to limit the rotating shaft 343. The rolling wheel 341 can adopt a bearing and be installed on the rotating shaft 343. A shaft sleeve 346 can also be provided on the rotating shaft 343. The shaft sleeve 346 is used to accurately limit the axial position of the rolling wheel 341 to prevent the rolling wheel 341 from contacting the bracket 342 and wearing, thereby reducing resistance.

[0047] It can be understood that notches 241 can be set on both sides of the upper end of the movable push plate 240, the roller assembly 340 is located in the notches, the roller assembly 340 is flush with the movable push plate 240, and then the ramp assembly 330 is installed above the roller assembly and the movable push plate 240 to assemble a flat structure, which is conducive to the movement of the movable push plate 240; the roller assembly 340 and the ramp assembly 330 can also be fixed as a whole and then installed at the upper end of the movable push plate 240.

[0048] Reference Figure 3 In some embodiments of the first aspect of the utility model, a side of the fixed plate 230 is provided with a baffle 231 to separate it into multiple channels, and the width of each channel matches the length of the test tube. The movable push plate 240 can push multiple test tubes at the same time to improve the loading efficiency. The number of baffles 231 can be two, three or more. A first baffle 232 and two second baffles 233 are provided above the middle fixed plate 230. A gap is provided between the topmost fixed plate 230 and the first baffle 232. The first baffle 232 is arranged obliquely, and the gap can allow the test tube to pass through. When the test tube is pushed up in a vertical state, the test tube in the vertical state contacts the first baffle 141, and the inclined first baffle 141 guides the test tube to fall back into the loading box 110, blocking the test tube in the vertical state from rising. The horizontally placed test tube can pass through the gap 142 to complete the loading. The second baffle 233 is fixed to the side of the first baffle 232 away from the top fixed plate 230. The second baffle 233 is arranged vertically and abuts the baffle bar 231. When the test tube spans two channels, the test tube will contact the second baffle 233. The second baffle 233 is used to guide the test tube to fall back into the loading box 110, thereby preventing the test tube in the wrong position from rising.

[0049] The second embodiment of the utility model provides a fully automatic sample processing system, including the test tube push plate loading assembly of the first embodiment. Among them, the sensor assembly 300 includes a first sensor 310 and a second sensor 320, the first sensor 310 is arranged at the lower end of the lowest fixed plate 230, and the second sensor 320 is arranged at the lower end of the middle (second lower) fixed plate 230. The first sensor 310 can be used to detect whether there is a test tube at the upper end of the lowest movable push plate 240, and the second sensor 320 can be used to detect whether there is a test tube at the upper end of the middle movable push plate 240. When there are test tubes on the bottom movable push plate 240, but there are no test tubes on the middle movable push plate 240, the control driving member 210 is started to continue pushing the test tubes upwards. When the second sensing member 320 detects the test tubes, the control driving member 210 stops and waits for instructions before continuing to load the materials. This can improve the loading efficiency, so that there are always test tubes waiting to be loaded on the middle movable push plate 240, avoiding the need to transport the test tubes from the bottom when they are needed, thereby reducing time consumption and improving efficiency.

[0050] In addition, the fully automatic sample processing system includes the entire technical solution of the test tube push plate loading assembly and has all the technical effects of the test tube push plate loading assembly, which will not be repeated.
