Abstract
Description
Technical Field
[0001] This utility model relates to the field of enzyme-labeled plate cleaning technology, and specifically to an enzyme-labeled plate cleaning device. Background Technology
[0002] ELISA plates are the core experimental tool for enzyme-linked immunosorbent assays. They are mainly made of polystyrene and adsorb biomolecules such as antigens and antibodies onto the bottom surface of the plate through mechanisms such as hydrophobic bonds and ionic bonds.
[0003] After use, ELISA plates need to be cleaned, which requires a cleaning device. While most cleaning devices can clean ELISA plates, they are not convenient for drying them. After cleaning, a small amount of liquid may remain, making the environment of the ELISA plate relatively humid. A humid environment is prone to the growth of bacteria or fungi, which may contaminate subsequent experimental samples. In addition, residual moisture can accelerate the hydrolysis and denaturation of the coated antibodies. Therefore, staff need to transfer the plates to a drying area for drying, which makes the operation more troublesome and affects the cleaning efficiency.
[0004] Therefore, an enzyme-labeled plate cleaning device is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an enzyme-labeled plate cleaning device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] An enzyme-linked immunosorbent assay (ELISA) plate washing device includes a base plate, a liquid aspirator, and a liquid dispensing device. A support cylinder is provided on the top of the base plate, and a rotating mechanism for circumferential rotation is provided on the support cylinder. Four positioning shells are provided on the rotating mechanism. An adjustment mechanism for adjusting the position of the liquid aspirator and the liquid dispensing device is provided on the surface of the base plate, and the liquid aspirator and the liquid dispensing device are mounted on the adjustment mechanism. A drying mechanism for drying the ELISA plate is provided on the surface of the base plate.
[0008] Furthermore, the rotating mechanism includes a motor, which is fixedly installed on the top of the base plate and located inside the support cylinder. A rotating component is rotatably installed on the inner wall of the support cylinder and is fixedly installed at the output end of the motor.
[0009] Furthermore, a disc is fixedly mounted on the top of the rotating component, and the disc is rotatably mounted on the top of the support cylinder. Four support plates are fixedly mounted on the surface of the disc, and a positioning shell is fixedly mounted on the surface of the support plates.
[0010] Furthermore, the adjustment mechanism includes a fixing plate, which is fixedly installed on one side of the base plate. A bracket is fixedly installed on the top of the fixing plate, and a cylinder is fixedly installed on the top of the bracket. A fixing frame is fixedly installed on the telescopic end of the cylinder.
[0011] Furthermore, a screw is rotatably installed inside the fixed frame, and a movable plate is threaded onto the outer wall of the screw. The movable plate is slidably installed on the inner wall of the fixed frame. Both the aspirator and the dispensing device are fixedly installed on the movable plate. A second motor is fixedly installed on one side of the fixed frame, and the screw is fixedly installed at the output end of the second motor.
[0012] Furthermore, the drying mechanism includes a mounting plate, which is fixedly mounted on one side of the base plate. A fixing frame is fixedly mounted on the top of the mounting plate. A fixing shell is fixedly mounted on the surface of the fixing frame. A fan blade is rotatably mounted on the fixing shell. A motor is fixedly mounted on the surface of the fixing frame, and the fan blade is fixedly mounted on the output end of the motor. An electric heating tube is fixedly mounted inside the fixing shell.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention, through the arrangement of a rotating mechanism, an adjusting mechanism, and a drying mechanism, allows for the precise positioning of an ELISA plate by placing it on the rotating mechanism from a positioning shell. The positioning shell, in conjunction with the plate, ensures the plate is correctly positioned and prevents misalignment. The rotating mechanism then rotates the first ELISA plate to one side of the adjusting mechanism. The adjusting mechanism also adjusts the positions of the aspirator and dispensing device. The dispensing device injects washing solution into the ELISA plate, while the aspirator draws the washing solution from the plate. After washing is complete, the rotating mechanism again rotates the first ELISA plate to one side of the drying mechanism. The second ELISA plate rotates to one side of the adjustment mechanism, while the drying mechanism dries the first ELISA plate to prevent residual cleaning solution. Once the first ELISA plate is dried and the second ELISA plate is cleaned, the rotating mechanism continues to rotate them, and the third ELISA plate enters one side of the adjustment mechanism, while the second ELISA plate enters one side of the drying mechanism. At this point, the first ELISA plate can be removed, while the fourth ELISA plate is ready for washing. This allows for alternating cleaning and drying of ELISA plates, improving cleaning efficiency. The operation is simple and highly practical. Attached Figure Description

[0025] like Figure 1-2 As shown, an enzyme-linked immunosorbent assay (ELISA) plate washing device includes a base plate 1, a liquid aspirator 6, and a liquid dispensing device 7. A support cylinder 2 is mounted on the top of the base plate 1, and a rotating mechanism 3 for circumferential rotation is mounted on the support cylinder 2. Four positioning shells 4 are mounted on the rotating mechanism 3. Figure 1-3 As shown, specifically, the rotating mechanism 3 includes a motor 301, which is fixedly installed on the top of the base plate 1. The motor 301 is located inside the support cylinder 2. A rotating component 302 is rotatably installed on the inner wall of the support cylinder 2, and the rotating component 302 is fixedly installed on the output end of the motor 301. A disc 303 is fixedly installed on the top of the rotating component 302, and the disc 303 is rotatably installed on the top of the support cylinder 2. Four support plates 304 are fixedly installed on the surface of the disc 303, and the positioning shell 4 is fixedly installed on the surface of the support plate 304.
[0026] More specifically, starting motor 301 drives rotating component 302 to rotate, while disk 303, four support plates 304 and four positioning shells 4 move accordingly, causing the four enzyme-labeled plates to alternate positions.
[0027] An adjustment mechanism 5 for adjusting the positions of the suction device 6 and the dispensing device 7 is provided on the surface of the base plate 1, and the suction device 6 and the dispensing device 7 are mounted on the adjustment mechanism 5; for example Figure 1-3 As shown, specifically, the adjusting mechanism 5 includes a fixed plate 501, which is fixedly installed on one side of the base plate 1. A bracket 502 is fixedly installed on the top of the fixed plate 501, and a cylinder 503 is fixedly installed on the top of the bracket 502. A fixed frame 504 is fixedly installed on the telescopic end of the cylinder 503. A screw 505 is rotatably installed inside the fixed frame 504. A movable plate 506 is threaded on the outer wall of the screw 505, and the movable plate 506 is slidably installed on the inner wall of the fixed frame 504. The aspirator 6 and the dispensing device 7 are both fixedly installed on the movable plate 506. A second motor 507 is fixedly installed on one side of the fixed frame 504, and the screw 505 is fixedly installed on the output end of the second motor 507.
[0028] More specifically, the cylinder 503 is supported by the cooperation of the fixed plate 501 and the bracket 502. When the cylinder 503 is started, the moving plate 506, the suction device 6 and the dispensing device 7 can be moved longitudinally. When the motor 507 is started, the screw 505 is rotated, which causes the moving plate 506 to move laterally, and the suction device 6 and the dispensing device 7 move accordingly. Thus, the height and lateral position of the suction device 6 and the dispensing device 7 can be adjusted.
[0029] A drying mechanism 8 for drying the enzyme-labeled plate is provided on the surface of the base plate 1; such as Figure 1-2 , Figure 4As shown, specifically, the drying mechanism 8 includes a mounting plate 801, which is fixedly mounted on one side of the base plate 1. A fixing frame 802 is fixedly mounted on the top of the mounting plate 801. A fixing shell 803 is fixedly mounted on the surface of the fixing frame 802. A fan blade 804 is rotatably mounted on the fixing shell 803. A motor 805 is fixedly mounted on the surface of the fixing frame 802, and the fan blade 804 is fixedly mounted on the output end of the motor 805. An electric heating tube 806 is fixedly mounted inside the fixing shell 803.
[0030] More specifically, with the cooperation of mounting plate 801, fixing frame 802 and fixing shell 803, the fan blade 804, motor 805 and electric heating tube 806 can be stably supported. The motor 805 drives the fan blade 804 to rotate and blow air onto the enzyme-labeled plate, while the electric heating tube 806 heats the air, so that the air blown onto the enzyme-labeled plate is hot air, thus improving the drying efficiency.
[0031] In summary, the vacuum negative pressure pump connects the aspirator 6 and the waste bottle to generate negative pressure to aspirate the liquid from the ELISA plate. The positive pressure delivery pump is used to push the washing solution from the storage bottle into the dispensing device 7. During use, the ELISA plate is placed on the rotating mechanism 3 from the positioning shell 4. With the cooperation of the positioning shell 4, the ELISA plate is positioned correctly and cannot be shifted. The rotating mechanism 3 rotates the first ELISA plate to one side of the adjusting mechanism 5. The adjusting mechanism 5 adjusts the positions of the aspirator 6 and the dispensing device 7. The dispensing device 7 injects the washing solution into the ELISA plate, while the aspirator 6 aspirates the washing solution from the ELISA plate. After washing is complete, the liquid is then transferred to the rotating mechanism... The rotating mechanism 3 rotates the first ELISA plate to one side of the drying mechanism 8, while the second ELISA plate rotates to one side of the adjusting mechanism 5. The drying mechanism 8 dries the first ELISA plate to avoid residual cleaning solution. After the first ELISA plate is dried and the second ELISA plate is cleaned, the rotating mechanism 3 continues to rotate them. The third ELISA plate enters one side of the adjusting mechanism 5, and the second ELISA plate enters one side of the drying mechanism 8. At this time, the first ELISA plate can be removed, while the fourth ELISA plate is ready to be cleaned. This allows for alternating cleaning and drying of ELISA plates, improving the cleaning efficiency of ELISA plates. The operation is simple and highly practical.
