Description

Technical Field

[0001] The utility model relates to the technical field of biological sample pre-treatment, and specifically refers to a microorganism efficient inoculation and disinfection device based on gravity sensing. Background Art

[0002] In conventional microbial inoculation equipment, a complex lifting mechanism is usually used to drive the inoculation loop to adjust the lifting height and mark the plate. After the marking is completed, the inoculation loop is moved to a specific position for high-temperature disinfection.

[0003] Conventional microbial inoculation equipment cannot automatically adjust the height of the inoculation loop according to the height of the culture medium in different culture dishes, which can easily cause the inoculation loop to bend and deform, affecting the inoculation effect. In addition, the separate disinfection position affects the overall efficiency of the equipment.

[0004] This solution adopts a gravity-sensing automatic adjustment structure, the inoculation loop automatically adjusts the height, and with a liftable disinfection device, marking and disinfection can be performed simultaneously. Utility Model Content

[0005] The utility model aims to at least solve the problems of poor inoculation effect and lack of disinfection structure in the prior art.

[0006] The present invention provides a gravity-sensing-based efficient microbial inoculation and disinfection device, which is achieved by the following specific technical means: comprising a culture dish tray moving mechanism, a marking lifting mechanism located in front of the culture dish tray moving mechanism, a marking rotating table installed on the top of the marking lifting mechanism, the marking lifting mechanism is used to drive the marking rotating table to rise and fall, and at the same time, multiple groups of inoculation rings are installed around the marking rotating table. When the culture dish tray moving mechanism drives the culture dish to move close to the inoculation ring, the inoculation ring movably connected to the marking rotating table contacts the material in the culture dish under the action of gravity, and the culture dish is driven to move by the culture dish tray moving mechanism to complete the inoculation. At the same time, a lifting disinfection mechanism is distributed on one side of the marking lifting mechanism. When one group of inoculation rings is in a working state, the other group of inoculation rings is in a disinfection state at the same time, and marking and disinfection are carried out simultaneously.

[0007] Preferred technical solution 1: The marking lifting mechanism includes a base frame and a lifting frame slidably arranged on the base frame, and a rotating motor 1 is installed on the lifting frame. The output shaft of the rotating motor 1 is fixedly connected to the marking rotating table for driving the marking rotating table to rotate. A plurality of groups of movable arms are hingedly installed on the peripheral side of the marking rotating table, and each group of the movable arms is fixedly connected to the end rod of the inoculation loop, and a guide support plate is fixed to the rear side of the lifting frame close to the culture dish tray moving mechanism, and both sides of the guide support plate are inclined surfaces. When the marking rotating table drives a group of movable arms to approach the guide support plate, the movable arms slide in contact with the inclined surface on one side of the guide support plate under the action of their own weight, so that the movable arms that were originally in a vertical state are gradually lifted up; when the marking rotating table drives a group of movable arms away from the guide support plate, the movable arms slide in contact with the inclined surface on the other side of the guide support plate, so that the movable arms that were originally in an upward state lose the upward support and resume the vertical state under the action of gravity.

[0008] Preferred technical solution two: a screw lift for a marking platform is fixed inside the base frame, a lifting end of the screw lift for the marking platform is fixedly connected to the lifting frame, and a position sensor 1 for detecting the position of the lifting frame is installed on the base frame to reflect the lifting height of the lifting frame.

[0009] Preferred technical solution three: The lifting disinfection mechanism includes a fixed plate located on one side of the base frame, a disinfection screw lift is fixed on the fixed plate, a lifting plate is fixed at the lifting end of the disinfection screw lift, an infrared sterilizer is installed on the lifting plate, and the top of the infrared sterilizer is inserted into the inoculation ring; a position sensor three is fixed on the lifting plate, and the position sensor three is used to detect the position of the lifting plate.

[0010] Preferred technical solution four: The culture dish tray moving mechanism includes an X-axis linear moving module located on the rear side of the base frame, a Y-axis linear moving module slidably arranged on the X-axis linear moving module, and a mounting frame slidably arranged on the Y-axis linear moving module, a rotating motor 2 is fixed on the mounting frame, and a rotating fixed tray is fixedly connected to the output shaft of the rotating motor 2, and a vacuum suction cup is installed on the rotating fixed tray.

[0011] Preferred technical solution five: the X-axis linear moving module is an X-axis linear guide rail, the bottom end of the Y-axis linear moving module is fixed on a slider on the X-axis linear guide rail, a belt is rotatably sleeved on the Y-axis linear moving module, and the mounting frame is fixed on the belt.

[0012] Preferred technical solution six: Position sensors 2 are fixed on both the X-axis linear motion module and the Y-axis linear motion module, and the two groups of position sensors 2 are used to detect the moving position of the Y-axis linear motion module and the moving position of the mounting frame respectively.

[0013] The above structure enables this solution to have the following beneficial effects:

[0014] 1. After the inoculated culture dish reaches the marking position, the lifting mechanism of the marking platform lowers the inoculation ring to the set position. The inoculation ring with a gravity sensing structure can be automatically adjusted up and down. Since there is no hard contact, the inoculation ring is not easy to deform. After the marking is completed, the inoculation ring rotates to the disinfection position, and the inoculation ring to be marked rotates to the marking position at the same time. The sterilizer lifts the sterilizer to the disinfection position to disinfect the inoculation ring, and the inoculation ring to be marked can be marked at the same time;

[0015] 2. The culture dish tray moving mechanism can drive the culture dish to move in multiple directions during inoculation to improve the inoculation effect;

[0016] 3. Inoculation streaking and inoculation loop disinfection are carried out simultaneously, which improves equipment processing efficiency, simplifies structure and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

When the culture dish tray moving mechanism 1 drives the culture dish to move close to the inoculation ring 32, the culture dish is driven to move by the culture dish tray moving mechanism 1 to complete the inoculation, and at the same time, a lifting disinfection mechanism 4 is distributed on one side of the marking lifting mechanism 2, and the used inoculation ring 32 is sent to the top of the lifting disinfection mechanism 4 by the rotation of the marking rotating platform 3. After the lifting disinfection mechanism 4 rises, the inoculation ring 32 enters the inner cavity for disinfection, so that when one group of inoculation rings 32 is in a working state, the other group of inoculation rings 32 is in a disinfection state, and marking and disinfection are carried out simultaneously.
