[0039] A sampler is a device used to place samples in specific positions or on carriers for further processing, analysis, or testing. In laboratories and industrial production, samplers play a crucial role. They can be operated manually or equipped with simple mechanical systems to achieve sample positioning and processing.

[0040] Manual samplers are one of the most common types. Operators place samples in predetermined positions through manual control. This type of sampler is simple and easy to use, suitable for small-scale sample processing, and has a low cost. However, manual samplers have low operation efficiency, and the accuracy of sample processing is affected by the skill level of the operator, etc.

[0041] Referring to Figures 1 to 12 , this application provides an automated sampler, which includes a box body 100, a sample adding mechanism 200, a sample injection tray 300, a pumping device 400, and a control board assembly 500.

[0042] The sample adding mechanism 200 is arranged inside the box body 100. The sample adding mechanism 200 includes a transverse movement device 210, a lifting device 220, a rotating device 230, and a sampling needle 240. The transverse movement device 210 is connected to the box body 100. The lifting device 220 is installed at the transverse movement end of the transverse movement device 210. The rotating device 230 is installed at the lifting end of the lifting device 220. The sampling needle 240 is installed at the rotating end of the rotating device 230. The sample injection tray 300 is slidably installed on the box body 100. The sample injection tray 300 is located below the sample adding mechanism 200. The sample injection tray 300 is provided with a sample tube installation groove and a detection card installation groove. The sample tube installation groove and the detection card installation groove are arranged on the transverse movement path of the transverse movement device 210. The pumping device 400 is arranged inside the box body 100. The pumping device 400 is communicated with the sampling needle 240. The control board assembly 500 is installed inside the box body 100. The control board assembly 500 is controllably connected to the sample adding mechanism 200, the sample injection tray 300, and the pumping device 400.

[0043] During operation, the sample tube 301 is installed in the sample tube installation groove, and the test card 302 is installed in the sample card installation groove. The control board assembly 500 controls the transverse movement device 210 and the lifting device 220, so that the sampling needle 240 moves above the sample tube 301. The control board assembly 500 controls the rotation device 230 to rotate the sampling needle 240, so that the sampling needle 240 is vertically aligned with the sample tube 301. Then the lifting device 220 drives the sampling needle 240 to extend into the sample tube 301. The pumping device 400 extracts the sample liquid in the sample tube 301. Then, driven by the lifting device 220 and the transverse movement device 210, the sampling needle 240 moves out of the sample tube 301 and moves above the test card 302. The pumping device 400 releases the sample liquid in the sampling needle 240 onto the test card 302, thus completing automatic sample loading. This sample loading device does not require manual sample loading and can perform automatic sample loading throughout the process, with higher operation efficiency and higher precision.

[0044] In order to clean the sampling needle 240 and the test card 302, in some embodiments, the automatic sampler further includes a cleaning device 600. The cleaning device 600 includes a bottom plate 601, a first delivery pump 602, a second delivery pump 603, a third delivery pump 604, a cleaning pool 605, a pure water tank 606 and a waste water tank 607. The first delivery pump 602, the second delivery pump 603, the cleaning pool 605 and the third delivery pump 604 are all installed on the bottom plate 601. The water inlets of the first delivery pump 602 and the second delivery pump 603 are both connected to the pure water tank 606 through pipelines. The water outlet of the first delivery pump 602 is connected to the water inlet of the pumping device 400 through a pipeline. The water outlet of the second delivery pump 603 is connected to the water inlet of the cleaning pool 605 through a pipeline. The water outlet of the cleaning pool 605 is connected to the water inlet of the third delivery pump 604 through a pipeline. The water outlet of the third delivery pump 604 is connected to the waste water tank 607 through a pipeline.

[0045] When it is necessary to clean the sampling needle 240, the transverse movement device 210 and the lifting device 220 drive the sampling needle 240 to insert into the cleaning pool 605. The first delivery pump 602 pumps the clear water in the pure water tank 606 to the pumping device 400, and then pumps it into the sampling needle 240 through the pumping device 400, so as to clean the inner wall of the sampling needle 240. The second delivery pump 603 pumps the clear water in the pure water tank 606 into the cleaning pool 605, so as to clean the outer wall of the sampling needle 240. Among them, the pumping device 400 can pump and spit out the water in the cleaning pool 605 multiple times to form multiple flushes of the inner wall of the sampling needle 240. The liquid flushed in the cleaning pool 605 is pumped out by the third delivery pump 604 and pumped into the waste water tank 607.

[0046] Among them, the first delivery pump 602 and the second delivery pump 603 are both diaphragm pumps, the pumping device 400 is a plunger pump, and the third delivery pump 604 is a waste water pump.

[0047] In order to clean the detection card 302, in some embodiments, a cleaning tube installation groove is further provided on the sample injection tray 300. The cleaning tube installation groove, the sample tube installation groove and the detection card installation groove are all located on the transverse movement path of the transverse movement device 210. Specifically, the cleaning tube installation groove, the sample tube installation groove and the detection card installation groove are located on the same straight line.

[0048] A cleaning tube 303 is installed in the cleaning tube installation groove. Before adding a sample to the detection card 302, the transverse movement device 210 and the lifting device 220 drive the sampling needle 240 to extend into the cleaning tube 303, pump out the cleaning liquid through the pumping device 400, and then spray the cleaning liquid onto the detection card 302 to clean the detection card 302.

[0049] A switch 101, a reset button 102, a defoaming button 103, a sample injection button 104, a cleaning button 105 and an indicator light 106 are further installed on the box body 100 of the present application. The switch 101, the reset button 102, the defoaming button 103, the sample injection button 104, the cleaning button 105 and the indicator light 106 are all connected to the control board assembly 500.

[0050] First, press the switch 101 to turn on the power of the device. After the indicator light 106 turns red, press the reset button 102 and wait for the device to be reset. After the reset is completed, the indicator light 106 turns green and the sample injection tray 300 exits, that is, the reset of the device is completed. At this time, place the detection card 302, the sample tube 301 containing the sample and the cleaning tube 303 containing the diluent on the sample injection tray 300, and then press the cleaning button 105. The sample injection tray 300 enters the box body 100 and waits for the detection card 302 to be cleaned. At this time, the indicator light 106 turns green and flashes. When the indicator light 106 stops flashing and the sample injection tray 300 exits, the cleaning is completed at this time. Press the sample injection button 104, the sample injection tray 300 enters the box body 100, and starts to add a sample to the detection card 302. At this time, the indicator light 106 turns green and flashes. When the indicator light 106 stops flashing, the sample injection tray 300 exits and the sample injection is completed.

[0051] If air bubbles are generated in the test card 302 during sample loading, the test card 302 can be defoamed by the defoaming button 103. The defoaming operation does not require placing the sample tube 301 and the cleaning tube 303 on the sample injection tray 300. Only the test card 302 with air bubbles needs to be placed on the sample injection tray 300. Then, after the sampling needle 240 self-cleans, the lateral movement device 210 and the lifting device 220 move the sampling needle 240 to the position of the test card 302 with air bubbles, suck the sample or cleaning liquid in the test card 302 and reinject it to achieve the defoaming function. Of course, if both test cards 302 have air bubbles, two operations are required, and the sampling needle 240 needs to self-clean before each operation.

[0052] It should be noted that the above different button operations can independently control the corresponding buttons to perform a certain operation.

The first pulley 2150 is connected to the power output end of the lateral movement drive device 214. The transmission belt 2152 connects the first pulley 2150 and the second pulley 2151, and the transmission belt 2152 is connected to the lateral movement slide 213. During the working process, the lateral movement drive device 214 drives the first pulley 2150 to rotate. The first pulley 2150 drives the transmission belt 2152, so that the transmission belt 2152 drives the lateral movement slide 213 to move horizontally on the lateral movement guide rail 212.

[0055] In addition, a lateral movement in-place sensor 216 is also provided on the substrate 211, and a lateral movement trigger tab is provided on the lateral movement slide 213.

The driving gear 2330 drives the driven gear 2331, and the driven gear 2331 drives the sampling needle 240 to swing and rotate.

[0061] The connecting columns 234 on both sides of the sampling needle 240 play a role in limiting, so that the sampling needle 240 can only rotate within the range of ±60°.

[0062] In addition, a rotary trigger flap is provided on the driven gear 2331, and a rotary in-place sensor 2310 is provided on the mounting seat 231. When the driven gear 2331 rotates to the point where the rotary trigger flap blocks the rotary in-place sensor 2310, it indicates that the sampling needle 240 reaches the reset origin at this time.
