Detailed Implementation
[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] like Figures 1-4 As shown, an automatic quantitative dispensing device for IVD reagents according to the present invention includes a workbench 1, a base 11 mounted on the upper side of the workbench 1, a rotor pump 12 mounted on the upper side of the base 11, a hopper 13 connected to the inlet of the rotor pump 12, the lower side of the hopper 13 being conical, a discharge pipe 14 connected to the outlet of the rotor pump 12, a feeding motor 15 mounted on the base 11, and the output shaft of the feeding motor 15 being drivenly connected to the pump shaft of the rotor pump 12.
[0024] The base 11 is fixed with a mounting bracket 2. A motor 21 is installed at the end of the mounting bracket 2. A connecting rod 22 is fixed to the output shaft of the motor 21. A receiving box 23 located below the discharge pipe 14 is fixed to the end of the connecting rod 22. A drain port 24 is provided at the center of the bottom of the receiving box 23. A sealing component is provided at the drain port 24.
[0025] The sealing assembly includes a cavity 241 opened on the lower side of the receiving box 23, the cavity 241 is connected to the drain port 24, a sealing block 242 is slidably arranged in the cavity 241, a spring 243 is provided between the rear side of the sealing block 242 and the side wall of the cavity 241, a top rod 244 that slides out of the cavity 241 is fixed on the front side of the sealing block 242, and a collection component that matches the receiving box 23 is provided on the rear side of the mounting frame 2;
[0026] The collecting components include an arc-shaped plate 3 fixed to the rear side of the mounting frame 2, the arc-shaped plate 3 being concentrically arranged with the output shaft of the motor 21, a boss 31 matching the top rod 244 being fixed in the middle of the arc-shaped plate 3, and a collecting tank 32 matching the receiving box 23 being fixed to the front side of the base 11.
[0027] In use, the reagent raw materials to be filled are put into the hopper 13. The staff places the reagent bottle at the lower end of the discharge pipe 14. By starting the discharge motor 15, the rotor pump 12 is driven to work, which transports the reagent in the hopper 13 to the discharge pipe 14. Finally, the reagent is added into the reagent bottle through the discharge pipe 14. The amount of material discharged per revolution of the rotor pump 12 is constant. By adjusting the number of revolutions, precise feeding can be achieved, which improves the accuracy of filling volume control, improves filling efficiency, and reduces waste.
[0028] After the quantitative filling of the reagent bottle is completed, the motor 21 is started to drive the receiving box 23 to be located below the discharge pipe 14, at this time, under the elastic force of the spring 243, the blocking block 242 blocks the liquid discharge port 24, so that the receiving box 23 can collect the liquid remaining in the discharge pipe 14, which not only avoids the liquid from dropping on the reagent bottle, ensures the cleanliness of the reagent bottle, but also avoids the waste of materials and saves the cost. When filling the new reagent bottle, the motor 21 drives the receiving box 23 to rotate to the rear side and away from the lower side of the discharge pipe 14, so as not to block the discharge pipe 14. When the receiving box 23 moves to the upper side of the collecting tank 32, the top rod 244 first contacts the arc-shaped plate 3, and then abuts against the boss 31 fixed on the arc-shaped plate 3, so as to drive the top rod 244 to move relative to the receiving box 23, thereby driving the blocking block 242 to slide in the cavity 241, so as to expose the liquid discharge port 24, and the liquid collected in the receiving box 23 flows into the collecting tank 32 through the liquid discharge port 24, thereby automatically processing and collecting the liquid in the receiving box 23.
[0029] The bottom of the receiving box 23 is provided with a conical table; the bottom of the receiving box 23 is conical through the conical table, so that the liquid in the receiving box 23 flows to the liquid discharge port 24.
[0030] The front side of the workbench 1 is provided with a supporting table 4, and the supporting table 4 is provided with an electric telescopic rod 41 on the front side and the rear side; the output shaft of the electric telescopic rod 41 is fixed with a conveying frame 42.
[0031] The conveying frame 42 comprises two transmission wheels rotatably installed at the two ends of the conveying frame 42, and a conveying belt 421 is arranged between the two transmission wheels; the lower side of the conveying frame 42 is provided with a second motor 422, and the output shaft of the second motor 422 is connected with the transmission wheels.
[0032] In this way, the reagent bottle can be placed in the middle of the two conveying frames 42, the second motor 422 drives the transmission wheels to rotate, so that the conveying belt 421 moves to convey the reagent bottle, the reagent bottle can be automatically conveyed to the lower side of the discharge pipe 14 without manual placement by the staff, the automation degree is higher, and the distance between the two conveying frames 42 can be controlled through the electric telescopic rod 41, so that the device is suitable for reagent bottles of different sizes, and the practicability of the device is higher.
[0033] The above embodiments only exemplarily illustrate the principle and effect of the device, and are not used to limit the device. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the device. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the device should be covered by the claims of the device.
