DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 7 The utility model provides a technical solution: a thin layer spotting auxiliary device for drug inspection, comprising a workbench 1, a thin sample plate 2 and a universal wheel 3, the top of the workbench 1 is butted with the thin sample plate 2, and the universal wheels 3 are installed on both sides of the bottom of the workbench 1, the outer wall of the thin sample plate 2 is provided with an auxiliary mechanism 4, and the auxiliary mechanism 4 includes a dual-axis motor 401, a rotating column 402, a transmission plate 403, a guide pin 404, a guide plate 405, a slide bar 406, a limit plate 407, a guide seat 408, a metal bellows 409 and a blow head 410, the outer wall of the guide seat 408 is installed with a metal bellows 409, and the side of the metal bellows 409 away from the guide seat 408 is butted with the blow head 410, the inside of the workbench 1 A dual-axis motor 401 is connected by bolts; a rotating column 402 is connected to the output end of the dual-axis motor 401, and a transmission plate 403 is fixedly connected to the side of the rotating column 402 away from the dual-axis motor 401; the transmission plate 403 is slidably connected to a guide pin 404 through a guide cavity, and a guide plate 405 is welded to the outer wall of the guide pin 404; a slide rod 406 is slidably connected to the inside of the guide plate 405, and a limiting plate 407 is welded to the top of the guide plate 405; a guide seat 408 is slidably connected to the outer wall of the limiting plate 407, and a sample cavity is provided inside the guide seat 408; a guide cavity is provided inside the transmission plate 403 and is connected to the guide pin 404, and both sides of the slide rod 406 are fixedly connected to the workbench 1 through extension blocks.

[0029] In specific implementation, when a thin layer spotting auxiliary device is needed to assist in the drug inspection process, in order to inspect more drugs and improve the inspection efficiency, since the limit plate 407 and the guide seat 408 are slidably connected, the guide seat 408 is manually pushed first, so that the guide seat 408 moves vertically along the limit plate 407, and since the guide seat 408 is connected to the blow head 410 through the metal bellows 409, the movement of the guide seat 408 drives the blow head 410 to move together until the guide seat 408 moves to the specified position. At this time, the drug solution in the pipette is dripped onto the thin sample plate 2 through the spotting cavity on the guide seat 408, and the output end of the blow head 410 is placed close to the spotting cavity in advance;

[0030] Then, the double-axis motor 401 is started. Since the output end of the double-axis motor 401 is connected to the rotating column 402, the double-axis motor 401 starts to drive the rotating column 402 to rotate. Since the rotating column 402 is connected to the transmission plate 403, the rotation of the rotating column 402 drives the transmission plate 403 to rotate together. Since the transmission plate 403 is slidably connected to the guide pin 404 through the guide cavity, the transmission plate 403 generates a thrust on the guide pin 404 when rotating, so that the guide pin 404 drives the guide plate 405 to move laterally along the slide bar 406. Since the top end of the guide plate 405 is welded to the limit plate 407, the movement of the guide plate 405 drives the limit plate 407 to move together.

[0031] Then, it is only necessary to start the dual-axis motor 401 to automatically control the lateral movement distance of the guide seat 408. Then, the inspector only needs to drop the medicine solution on the thin sample 2 through the spotting chamber when the guide seat 408 stops, and there is no need to confirm the spotting interval with a ruler. The blow dryer can be used at any time afterwards through the blow head 410. The inspector does not need to spot with one hand. After the spotting is completed, the blow head 410 can be used to assist in drying the spotting spots, thereby achieving spotting and drying at the same time, thereby improving the inspection efficiency. When the thin layer spotting auxiliary device for drug inspection is used, it is convenient to improve the inspection efficiency.

[0032] See also Figure 1-Figure 5 , Figure 8 and Fig. 9It can be seen that a fixing mechanism 5 is provided on the outer wall of the universal wheel 3, and the fixing mechanism 5 includes a fixing seat 501, a rotating seat 502, a pressing rod 503, a support rod 504, a spring 505 and a fixed suction cup 506. The middle part of the outer wall of the workbench 1 is connected with the fixing seat 501 by bolts; a rotating seat 502 is welded on the side of the outer wall of the workbench 1 close to the fixing seat 501, and a pressing rod 503 is connected inside the rotating seat 502, and the pressing rod 503 is slidably connected to the support rod 504 through a guide groove; a spring 505 is sleeved on the middle part of the outer wall of the support rod 504, and a fixed suction cup 506 is docked at the bottom end of the support rod 504; the fixing seat 501 and the support rod 504 are slidably connected, and an elastic telescopic mechanism is formed between the fixing seat 501, the support rod 504 and the spring 505.

[0033] In specific implementation, during the drug inspection process, when a thin layer spotting auxiliary device is needed for assistance, in order to prevent the workbench 1 from being offset due to collision and affecting the inspection work, when it needs to be fixed, since the rotating seat 502 is connected to the pressing rod 503, the pressing rod 503 is manually pushed downward to make the pressing rod 503 rotate clockwise, and since the pressing rod 503 and the support rod 504 are in a sliding connection, the rotation of the pressing rod 503 generates a thrust on the support rod 504, so that the support rod 504 moves downward along the fixed seat 501, and since the bottom end of the support rod 504 is in contact with the fixed suction cup 506, the movement of the support rod 504 drives the fixed suction cup 506 to move together;

[0034] When the support rod 504 moves downward, it squeezes the spring 505, causing the spring 505 to deform. Then, the elastic force generated by the reset of the spring 505 assists the pressing rod 503 to move upward until the fixed suction cup 506 fits against the smooth ground, thereby increasing the fixed area and friction between the workbench 1 and the ground, and then improving the stability of the workbench 1, preventing it from shifting due to collision, thereby affecting the inspection of the medicine, thereby playing a role in preventing shifting when the thin layer spotting auxiliary device for medicine inspection is used.

[0035] In summary, when the thin layer spotting auxiliary device for drug inspection is used, the workbench 1 is first moved to the specified position through the universal wheel 3, and then the inspector draws lines at the specified intervals to determine the spotting position of the drug. After that, the inspector uses a pipette to absorb the drug to be tested, and then drops the drug on the thin sample 2. Finally, the spotting spots on the thin sample 2 are blown dry by the blower head 410, and then the spotting work is completed, thereby affecting the use of the thin layer spotting auxiliary device. This is a prior art and will not be elaborated on here. Through the auxiliary mechanism 4, the inspector only needs to drop the drug solution on the thin sample 2 when the guide seat 408 pauses, without the need to laboriously confirm the spotting interval through a ruler, and can blow dry while spotting, thereby improving the inspection efficiency. The fixing area and friction between the workbench 1 and the ground are increased by the fixing mechanism 5, thereby improving the stability of the workbench 1, preventing it from being offset due to collision, and then affecting the inspection work of the drug. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
