[0056] As shown in Figure 2 、 Figure 7 、 Figure 10 The mounting plate 202 is provided with a placing clamping groove 207, and the slide glass body 203 can be clamped in the placing clamping groove 207, so that the slide glass body 203 cannot be easily displaced in the subsequent series of operations. An arc-shaped groove 208 is additionally arranged on the placing clamping groove 207, and a collection groove 209 in the arc-shaped groove 208 can be used to collect excess liquid that may be generated during the operation process, so as to avoid pollution to the sample. Furthermore, a taking groove 210 is arranged on the mounting plate 202, the taking groove 210 is arranged in an arc shape and is in communication with the arc-shaped groove 208, so that the slide glass body 203 can be easily taken out by the operator, and at the same time, excess liquid can flow into the arc-shaped groove 208 through the taking groove 210. The inner part of the first shell 31 is provided with a placing rack 33, and a plurality of limit strips 34 are arranged in the placing rack 33 in an orderly manner. The distance between the limit strips 34 is equal to the width of the mounting plate 202, so that the mounting plate 202 is preliminarily limited and guided when the mounting plate 202 enters, and the position is ensured to be accurate. The pushing-in plate 35 is slidably arranged on the placing rack 33, and the sliding structure arranged on the placing rack 33 is connected with the pushing-in plate 35. When it is necessary to further push the mounting plate 202 into position, the pushing-in plate 35 can smoothly slide along the sliding structure, thereby assisting the entire process.

[0057] A positioning method using the above-mentioned RFID slide positioning device comprises the following steps:

[0058] Step one: placement of the slide body;

[0059] The operator needs to place the slide body 203 in the placement card slot 207 of the mounting plate 202. The push-in plate 35 on the placement rack 33 is already in the initial standby position under the action of the sliding structure, and the sufficient space reserved by the push-in plate 35 facilitates the subsequent smooth placement of the mounting plate 202. Then, the operator manually places the mounting plate 202 on the placement rack 33, so that the mounting plate 202 is located between the multiple sets of limiting strips 34, thereby achieving the preliminary limiting and guiding effect of the mounting plate 202, and ensuring the accurate position of the mounting plate 202 to the greatest extent and avoiding large deviation. The skid 201 is stably located at one end of the placement rack 33, and the placement frame 204 on the skid 201 is in contact with the placement rack 33. When the sliding structure is running, the push-in plate 35 pushes the mounting plate 202 to move slowly until the mounting plate 202 is stably placed in the placement frame 204;

[0060] Step two: preliminary positioning of the reader-writer;

[0061] When the mounting plate 202 is successfully installed in the placement frame 204 and is just below the reader-writer 32 in the first housing 31, the reader-writer 32 is quickly started, and the radio frequency signal emitted by the reader-writer 32 communicates with the RFID tag on the slide body 203 to quickly read the sample information, which is transmitted to the background in an instant. At the same time, the controller preliminarily judges the subsequent processing flow of the slide body 203 and the target position that should be rushed to, laying the foundation for a series of subsequent operations;

[0062] Step three: positioning of the sample preparation area;

[0063] The first conveyor belt 12 is connected to the instruction to start running smoothly, and the sled 201 and the slide body 203 are stably transported into the second shell 401 of the sample preparation part; as soon as it enters this critical area, the positioning assembly immediately enters the working state, and the positioning motors 411 on both sides of the connecting block 406 are started, which output strong power to drive the positioning frame 404 and the positioning piece 405 to rotate until they are parallel to the mounting plate 202. At this time, the rubber block 413 arranged on the positioning frame 404 also contacts the slide body 203 by chance, limiting the movement of the slide body 203 from the side; during this period, the controller receives information from the reader 32 on the one hand, and also receives the dynamic captured by the visual recognition module 516 in real time on the other hand, and controls the operation of the rotating motor 512 according to these comprehensive information; after receiving the instruction, the rotating motor 512 drives the rotating disc 511 to rotate at a constant speed, moves the corresponding sample reagent tube to the entrance and exit 514, and facilitates the operator to take it by hand; the operator holds the dropper and sucks the sample in the sample reagent tube; at the same time, the laser 403 in the positioning assembly is always in the starting state, and when the slide body 203 moves into the second shell 401, the laser beam emitted by the laser 403 stably irradiates the center position of the slide body 203; and the positioning ring 414 arranged at one end of the positioning piece 405 on the assembly component is also located at the center position of the slide body 203, and a good gap is left between the slide body 203 and the positioning ring 414. Through the cooperation of the laser 403 and the positioning piece 405, a double-layer positioning effect is formed, so that the operator can move the dropper containing the sample into the second shell 401, and align the intersection of the positioning ring 414 and the laser beam with the slide body 203. The sample is carefully dropped on the slide body 203; after the sample is dropped, one of the positioning motors 411 is started for the placement of the cover glass, the positioning piece 405 is homed first, the operator gently contacts one end of the cover glass with the positioning plate 412, and the cover glass is placed on the slide body 203 by means of the positioning effect of the positioning plate 412; after the series of operations are completed, the positioning motor 411 is started again to drive the positioning frame 404 and the positioning piece 405 to return to the original position, and the first conveyor belt 12 is also started again to drive the sled 201 to continue moving forward;

[0064] Step four: sample processing operation;

[0065] When the slide body 203 is positioned, the slide body 203 is moved under the support of the sliding sledge 201 to below the preparation rack 501; at this moment, a plurality of groups of liquid storage tanks 506 arranged on the moving plate 502 on the preparation rack 501 store physiological saline or other liquids such as staining agents respectively, according to the instruction issued by the controller, the moving plate 502 moves through the sliding structure on both sides thereof to move the corresponding liquid storage tank 506 to above the slide body 203; the water pump 507 is started, which extracts the physiological saline or the staining agent in the liquid storage tank 506 through the conduit by suction and uniformly drops on the slide body 203 through the drop needle 508, to complete the sample processing operation; in this process, the lamp panel 415 continuously provides bright and stable illumination, facilitating them to clearly observe the drop condition and timely discover and handle possible problems.

[0066] Step five: push output;

[0067] After a series of treatments, the slide body 203 is steadily moved to the pushing assembly under the continuous driving of the first conveying belt 12; when moving into the pushing assembly, the sliding sledge 201 moves to the second conveying belt 601 according to the predetermined route, at this moment, the plurality of groups of second conveying belts 601 and the plurality of groups of third conveying belts 602 in the pushing assembly synergistically exert force; the second conveying belt 601 close to the first conveying belt 12 slowly rises under the action of the lifting structure until parallel to the third conveying belt 602 on the top of the support frame 604, the sliding sledge 201 is smoothly moved to the third conveying belt 602 and continues to move forward until gently contacts with the pushing plate 609 on the third shell 603; at the critical moment, the pushing electric cylinder 605 is quickly started, the pushing block 607 at the shaft end thereof is like an arm, penetrates through the pushing through slot 206 on the placement frame 204 and contacts with the mounting plate 202; at the same time, the limiting sliding groove 610 on both sides of the placement frame 204 cooperates with the limiting sliding block 205 on both sides of the mounting plate 202, so that the mounting plate 202 and the slide body 203 are stably moved forward under the pushing of the pushing block 607 until the slide body 203 is smoothly pushed out, which is convenient for the operator to take.

[0068] Embodiment two:

[0069] Based on the RFID slide positioning device and positioning method provided in embodiment one of the application, the embodiment two of the application provides an RFID slide positioning device and positioning method. The embodiment two is only a preferred mode of the embodiment one, and the implementation of the embodiment two does not affect the separate implementation of the embodiment one. The embodiment two of the application will be further described below.

[0070] As Figure 2 , Figures 8 to 10As shown, the mounting plate 202 is provided with a placing slot 207, and the slide body 203 is clamped in the placing slot 207. The placing slot 207 is further provided with an arc-shaped slot 208. The mounting plate 202 is further provided with an assembly slot 211. The bottom of the arc-shaped slot 208 is provided with a liquid leakage slot 212. The arc-shaped slot 208 is connected with the assembly slot 211 through the liquid leakage slot 212, thereby forming a liquid drainage channel. A detachable collection box 213 is arranged in the assembly slot 211. When liquid flows into the arc-shaped slot 208 by accident, the liquid can flow into the collection box 213 through the liquid leakage slot 212, thereby avoiding liquid pollution or affecting equipment operation. In addition, the mounting plate 202 is further provided with a taking slot 210. The taking slot 210 is arranged in an arc shape and is connected with the arc-shaped slot 208. When the slide body 203 needs to be taken out, a finger can apply force along the taking slot 210. At the same time, excess liquid enters the arc-shaped slot 208 through the taking slot 210 and then enters the collection box 213 through the liquid leakage slot 212. The first housing 31 is internally provided with a placing rack 33. A plurality of limiting strips 34 are arranged on the placing rack 33 in an orderly manner. The spacing between the limiting strips 34 is equal to the width of the mounting plate 202. When the mounting plate 202 enters, the mounting plate 202 is preliminarily limited and guided, thereby ensuring the position accuracy. The placing rack 33 is further slidably provided with a pushing plate 35. The sliding structure on the placing rack 33 is connected with the pushing plate 35. When the mounting plate 202 needs to be further pushed into position, the pushing plate 35 can smoothly slide along the sliding structure, thereby assisting the entire process.

[0071] The difference between the second embodiment and the first embodiment is that the mounting plate 202 is provided with the assembly slot 211. The assembly slot 211 is connected with the arc-shaped slot 208 through the liquid leakage slot 212, and the collection box 213 is arranged in the assembly slot 211. Excess liquid can stably flow into the collection box 213 along the arc-shaped slot 208 and through the guidance of the liquid leakage slot 212. When cleaning is needed, the collection box 213 can be taken out, thereby quickly cleaning the liquid in the interior and simplifying the cleaning process. The remaining conditions are the same as those of the first embodiment, and thus the second embodiment will not be described again.

At the same time, after the sample drips onto the slide body (203), the cover glass is placed, one group of the positioning motors (411) is started, the positioning member (405) is first returned to its position, and then one end of the cover glass is brought into contact with the positioning plate (412), and the positioning plate (412) plays a positioning role, and the cover glass is slowly placed on the slide body (203); after the steps are completed, the other group of the positioning motors (411) is started, the positioning frame (404) is returned to its position, and the first conveyor belt (12) is started, driving the sled (201) to continue moving; Step 4: Sample processing operation; After the glass slide body (203) is positioned, the glass slide body (203) is moved to the bottom of the preparation rack (501) via the sled (201). A plurality of liquid storage tanks (506) are provided on the movable plate (502) on the preparation rack (501). Physiological saline or dye is stored in the plurality of liquid storage tanks (506). According to the information sent by the controller, the movable plate (502) moves via the sliding structure, and the corresponding liquid storage tank (506) is moved to the top of the glass slide body (203). The water pump (507) is started, and the physiological saline or dye in the liquid storage tank (506) is extracted through the catheter and dripped onto the glass slide body (203) by the dripping needle (508), thereby completing the sample processing operation. The lamp panel (415) provides lighting to facilitate the operator to observe the dripping situation. Step 5: Push output; The processed glass slide body (203) moves toward the pushing assembly driven by the first conveyor belt (12). When moving in the pushing assembly, the sled (201) moves to the second conveyor belt (601). The multiple groups of the second conveyor belts (601) and the multiple groups of the third conveyor belts (602) in the pushing assembly work together. A group of the second conveyor belts (601) close to the first conveyor belt (12) rises under the action of the lifting structure until it is parallel to the third conveyor belt (602) on the top of the support frame (604). The sled (201) moves to the third conveyor belt (602) and The push plate (609) on the third housing (603) is moved to contact the push plate (609) on the third housing (603); the push electric cylinder (605) is started, and the push block (607) at the shaft end thereof passes through the push slot (206) on the placement frame (204) and contacts the mounting plate (202); the limiting slide grooves (610) on both sides of the placement frame (204) cooperate with the limiting sliders (205) on both sides of the mounting plate (202), so that the mounting plate (202) and the slide body (203) move forward smoothly under the push of the push block (607) until the slide body (203) is pushed out, making it easy for the operator to take it.
