Description

Technical Field

[0001] The present invention relates to the technical field of vaccine detection, and specifically provides a vaccine detection device and a detection method. Background Art

[0002] Vaccines refer to biological products made from various pathogenic microorganisms for preventive vaccination. Among them, vaccines made from bacteria or spirochetes are also called bacterins. Vaccines are divided into live vaccines and inactivated vaccines. Common live vaccines include Bacillus Calmette-Guérin (BCG), poliomyelitis vaccine, measles vaccine, plague bacterin, etc. Common inactivated vaccines include pertussis bacterin, typhoid bacterin, meningococcal vaccine, cholera bacterin. During the production and processing of vaccines, it is necessary to detect the sealing performance of the vaccine filling bottles, so a vaccine detection device is required.

[0003] In the process of implementing the invention, the inventors found that at least the following problems in the prior art have not been solved. During use, the traditional vaccine detection device cannot adjust the position of the vaccine filling bottle during transportation. When the vaccine filling bottle is not in the middle of the conveyor belt, it is easy to cause the detection mechanism not to fit with it. It also cannot automatically position vaccine filling bottles of different sizes, and the speed of the vaccine detection device for detecting the sealing performance of the filling bottles containing vaccines is relatively slow. Therefore, new technical solutions need to be designed to solve this problem. Summary of the Invention

[0013] As a preferred embodiment of the present invention, the installation end of the third electric push rod is fixedly connected to one side of the mounting plate, the output end of the third electric push rod is fixedly connected to one side of the correction plate, and the bottom end of the correction plate is slidably connected to the upper surface of the vaccine delivery mechanism.

[0014] As a preferred embodiment of the present invention, for the detection method of the vaccine detection device, the detection steps are as follows:

[0015] S1. When detecting the sealing performance of the vaccine filling bottles, first adjust the distance between the two correction plates according to the diameter of the filling bottles. At this time, the controller will control the third electric push rod to operate, so that the output end of the third electric push rod drives the correction plates to move relatively or towards each other, thus realizing the adjustment of the distance between the correction plates;

[0016] S2. Then adjust the distance between the two infrared sensors according to the diameter of the filling bottles. First, loosen the limit bolt from the threaded hole, and then let the adjustment plate move relatively or towards each other in the adjustment groove, so as to realize the adjustment of the distance between the two infrared sensors;

[0017] S3. Then place the filling bottles filled with vaccine on the conveyor belt. At this time, the controller will control the conveyor motor to operate, so that the conveyor motor drives the conveyor belt to rotate through the rotating shaft, thereby automatically conveying the filling bottles filled with vaccine on the conveyor belt;

[0018] S4. When the vaccine passes through the correction plates, it will be automatically corrected to the center. When both infrared sensors detect the filling bottles filled with vaccine, the controller will control the conveyor motor to stop operating, so as to achieve automatic positioning of the filling bottles filled with vaccine, and control the first electric push rod to operate. At this time, the first electric push rod will drive the detection mechanism to move downward, so that the sealing ring on the detection mechanism fits on the outer surface of the filling bottle filled with vaccine, thereby improving the sealing performance between the detection mechanism and the filling bottle filled with vaccine;

[0019] S5. The controller will also control the air blower to operate. At this time, the air blower will convey air into the detection mechanism through the flexible air pipe. When the conveyed air volume reaches the detection value of the air flow sensor, the controller will control the air blower to stop operating. At this time, the pressure sensor will transmit the detected air pressure value to the controller;

[0020] S6. When the air pressure value is the same as the set value of the pressure sensor, the controller will control the first electric push rod to drive the detection mechanism to reset, and control the conveyor motor to operate, so that the filling bottles filled with vaccine continue to be conveyed. When the air pressure value is lower than the set value of the pressure sensor, the controller will first control the second electric push rod to operate. At this time, the second electric push rod will drive the push plate to move towards the position of the adjustment plate, so as to push the filling bottles with poor sealing performance to the edge of the conveyor belt. Then, let the push plate reset, and then control the first electric push rod to drive the detection mechanism to reset, and control the conveyor motor to operate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention can not only adjust the position of the vaccine filling bottles during transportation, avoiding the situation where the vaccine filling bottles are not in the middle of the conveyor belt, resulting in the detection mechanism being unable to fit with them, but also can automatically position vaccine filling bottles of different sizes, and can automatically detect the sealing performance of filling bottles containing vaccines of different sizes. This speeds up the sealing detection speed of the vaccine detection device for filling bottles containing vaccines, improves the sealing performance between the detection mechanism and the filling bottles containing vaccines, and enhances the efficiency of detecting the sealing performance of the vaccine filling bottles.
