Description

Technical Field

[0001] The utility model belongs to the technical field of microorganism inoculation, and relates to a microorganism automatic inoculation device. Background Art

[0002] The inoculation and cultivation of microorganism colonies is an important task in aspects such as medical and health, inspection and quarantine, disease control, food safety, etc. Currently, the instruments used for microorganism inoculation and cultivation are an inoculation needle and a glass culture dish. There is a culture medium in this glass culture dish. The operator holds the inoculation needle dipped with microorganisms and gently adds a small amount of microorganism samples onto the surface of the culture medium in the glass culture dish. The operation efficiency is relatively low, and manual operation has high requirements for the entire aseptic environment, requiring cumbersome operations, which are time-consuming and laborious. Summary of the Invention

[0003] The purpose of the utility model is to propose a microorganism automatic inoculation device in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the operation efficiency of microorganism inoculation.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] A microorganism automatic inoculation device includes a frame and a turntable rotatably arranged on the frame. It is characterized in that the turntable has a number of placement grooves arranged along its circumference. The frame is sequentially provided with an ultraviolet lamp, a scribing machine, and a bacterial liquid inoculation machine along the circumference. The scribing machine and the bacterial liquid inoculation machine are respectively arranged directly above the placement grooves. The scribing machine can move up and down relative to the frame. The bacterial liquid inoculation machine includes a number of liquid storage cylinders arranged adjacent to each other on the frame. The liquid storage cylinders are arranged vertically and have liquid outlets at the lower part. A piston rod that can move up and down is arranged in the liquid storage cylinder. The frame is also provided with a pneumatic gripper that can move back and forth between two adjacent placement grooves.

[0006] This microorganism automatic inoculation device, by setting an ultraviolet lamp, a scribing machine, a bacterial liquid inoculation machine, a pneumatic gripper that can move back and forth between two adjacent placement grooves, and a rotatable turntable with placement grooves on the frame, the operator only needs to place the culture dish containing the culture medium in the placement groove of the turntable to achieve automatic disinfection of the culture dish, automatic opening and closing of the culture dish lid, automatic scribing of the culture medium in the culture dish, and automatic inoculation of the bacterial liquid, thereby improving the operation efficiency of microorganism inoculation.

[0007] In the above-mentioned microbial automatic inoculation device, a mounting seat is detachably arranged on the frame. A number of first cylinders are arranged on the mounting seat. The first cylinders and the liquid storage cylinders are arranged vertically opposite to each other one by one, and the output shafts of the first cylinders are arranged vertically downward and connected to the piston rods in the corresponding liquid storage cylinders. The detachable arrangement of the mounting seat on the frame facilitates the overall disassembly and assembly of the subsequent bacterial liquid inoculator, so as to facilitate the addition of bacterial liquid and cleaning of the liquid storage cylinder of the bacterial liquid inoculator.

[0008] In the above-mentioned microbial automatic inoculation device, a second cylinder is arranged on the frame. The output shaft of the second cylinder is arranged vertically downward and connected to the scribing machine. The scribing machine includes a number of scribing blades arranged in a crosswise manner. The scribing blades are respectively arranged vertically and intersect at the same intersection point. The several scribing blades of the scribing machine are in a "rice" shape, which can better scribe a "rice" shaped wire groove on the culture medium of the petri dish, facilitating the subsequent diffusion of the bacterial liquid along the wire groove.

[0009] In the above-mentioned microbial automatic inoculation device, two baffle plates are also arranged on the frame. The two baffle plates are respectively located on both sides of the bacterial liquid inoculator. The two baffle plates can, to a certain extent, prevent the bacterial liquid from escaping to both sides and avoid contaminating the subsequent petri dishes.

[0010] In the above-mentioned microbial automatic inoculation device, an inkjet printer that can move up and down relative to it is also arranged on the frame. The inkjet printer is arranged directly above the placement groove and beside the bacterial liquid inoculator. The inkjet printer can print a predetermined mark on the lid of the petri dish, facilitating the subsequent identification and search for the petri dish.

[0011] In the above-mentioned microbial automatic inoculation device, a third cylinder and a pair of first slide rails are also arranged on the frame. A sliding seat is slidably arranged on the two first slide rails. The output shaft of the third cylinder is arranged horizontally and connected to the sliding seat. A fourth cylinder and a pair of second slide rails are arranged on the sliding seat. The pneumatic gripper is slidably arranged on the two second slide rails. The output shaft of the fourth cylinder is arranged horizontally and connected to the pneumatic gripper. The two jaws of the pneumatic gripper face the turntable. The above structure enables the pneumatic gripper to better perform the opening and closing operations of the petri dish lid.

[0012] In the above-mentioned microbial automatic inoculation device, a casing covering the periphery of the turntable is also arranged on the frame. The casing can play a role in dust prevention and protection, ensuring the inoculation quality of this microbial automatic inoculation device.

[0013] Compared with the prior art, the advantages of this automatic microorganism inoculation device are as follows: This automatic microorganism inoculation device can achieve automatic disinfection of culture dishes, automatic opening and closing of the lids of culture dishes, automatic scribing of the culture media in culture dishes, automatic inoculation of bacterial solutions, and automatic marking of culture dishes, thereby improving the operation efficiency of microorganism inoculation.

An air-operated gripper 8 that can move back and forth between two adjacent placement grooves 2a is also arranged on the frame 1.

[0023] Specifically, referring to Figure 1-6 , a mounting seat 9 is detachably arranged on the frame 1. A number of first cylinders 10 are arranged on the mounting seat 9. The first cylinders 10 and the liquid storage cylinders 5a are arranged vertically opposite to each other one by one. The output shaft of the first cylinder 10 is arranged vertically downward and connected to the piston rod 5b in the corresponding liquid storage cylinder 5a. A second cylinder 11 is arranged on the frame 1. The output shaft of the second cylinder 11 is arranged vertically downward and connected to the scribing machine 4. The scribing machine 4 includes a number of scribing blades 4a arranged in a crosswise manner. The scribing blades 4a are respectively arranged vertically and intersect at the same intersection point. A third cylinder 14 and a pair of first slide rails 6 are also arranged on the frame 1. A sliding seat 16 is slidably arranged on the two first slide rails 6. The output shaft of the third cylinder 14 is arranged horizontally and connected to the sliding seat 16. A fourth cylinder 17 and a pair of second slide rails 15 are arranged on the sliding seat 16. The air-operated gripper 8 is slidably arranged on the two second slide rails 15. The output shaft of the fourth cylinder 17 is arranged horizontally and connected to the air-operated gripper 8. The two jaws of the air-operated gripper 8 face the turntable 2.

[0024] In this embodiment, it is preferred that two baffle plates 12 are further arranged on the frame 1, and the two baffle plates 12 are respectively located on both sides of the bacterial liquid inoculator 5. It is preferred that an inkjet printer 13 that can move up and down relative to the frame 1 is further arranged on the frame 1. The inkjet printer 13 can be driven to move up and down by a cylinder. The output shaft of the cylinder is arranged vertically downward and connected to the inkjet printer 13. The inkjet printer 13 is arranged directly above the placement groove 2a and beside the bacterial liquid inoculator 5. A casing 7 covering the periphery of the turntable 2 is also arranged on the frame 1.

[0025] The working principle of this automatic microorganism inoculation device is described below:

[0026] The operator first places the culture dish containing the culture medium in the placement groove 2a of the turntable 2. The culture dish first rotates with the turntable 2 to the lower part of the ultraviolet lamp 3, and the ultraviolet lamp 3 disinfects the culture dish by irradiating it. Then, the disinfected culture dish continues to rotate with the turntable 2 to the lower part of the scribing machine 4. Then, the third cylinder 14 drives the sliding seat 16 to move towards the position close to the scribing machine 4. Next, the fourth cylinder 17 drives the pneumatic gripper 8 to move towards the culture dish under the scribing machine 4 and remove the lid of the culture dish. Then, the fourth cylinder 17 drives the pneumatic gripper 8 to return with the lid of the culture dish along the original path. Next, the second cylinder 11 drives the scribing machine 4 to move downwards until the scribing blade 4a of the scribing machine 4 contacts the culture medium and completes scribing. The scribed culture medium has a scribing groove with the same shape as the scribing blade 4a. Then, the second cylinder 11 drives the scribing machine 4 to reset. Then, the scribed culture dish continues to rotate with the turntable 2 to the lower part of the bacterial liquid inoculator 5. A plurality of liquid storage cylinders 5a on the bacterial liquid inoculator 5 contain different bacterial liquids respectively. According to the inoculation requirements of this time, the first cylinder 10 above the corresponding bacterial liquid drives the piston rod 5b connected to it to move downwards, extruding the bacterial liquid in the liquid storage cylinder 5a from the liquid outlet 5a1 and dripping it into the scribing groove of the culture medium. The bacterial liquid can spread along the scribing groove by itself. Then, the third cylinder 14 drives the sliding seat 16 to move towards the position close to the bacterial liquid inoculator 5. Then, the fourth cylinder 17 drives the pneumatic gripper 8 with the lid of the culture dish to move towards the culture dish located under the bacterial liquid inoculator 5 and cover the lid back onto the culture dish. Then, the culture dish continues to rotate with the turntable 2 to the lower part of the inkjet printer 13. Then, the inkjet printer 13 is driven by a cylinder to move downwards to the culture dish and print a predetermined mark on the lid of the culture dish for convenient subsequent identification and search. Then, the culture dish with the predetermined mark printed continues to rotate with the turntable 2 to the window of the machine housing 7. Then, the operator can take down this culture dish. Such operations are continuously cycled.
