Description

Technical Field

[0001] This utility model relates to the field of bioengineering equipment, specifically a dual-station multi-marking head linkage marking device. Background Technology

[0002] Laboratories and medical institutions mainly rely on two methods for microbial culture: manual streaking and single-station streaking systems. Manual streaking is a traditional method in which laboratory personnel manually operate an inoculation loop or similar tool to streak microorganisms on the surface of the culture medium. Single-station streaking systems represent a step towards automation, which can reduce the influence of human factors to a certain extent.

[0003] While both methods have their advantages, they also present significant problems. Manual streaking, due to its inherent inefficiency and high dependence on operator skill, leads to inconsistent streaking quality and difficulty in controlling sample distribution, directly impacting the accuracy and validity of experimental data. Single-station streaking systems, while improving operational consistency, severely limit efficiency by processing only one culture medium at a time, especially when processing large numbers of samples. Therefore, there is currently a lack of a technological solution on the market that can improve efficiency while ensuring streaking quality and consistency, and is suitable for batch processing of microbial culture media. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A dual-station multi-marking head linkage marking device, characterized in that it comprises:

[0006] Device casing;

[0007] A culture medium transfer drawer, wherein the outer surface of the device housing is provided with an opening adapted to the culture medium transfer drawer;

[0008] The streaking assembly includes several streaking sections disposed inside the device housing for streaking culture medium, and a motion control device capable of driving the streaking sections to move horizontally.

A track limiting structure is provided between the fixed head and the scribing head to restrict the separation of the scribing head and the fixed head.

[0020] Beneficial effects

[0021] Compared with existing technologies, this utility model, through its multi-layered culture medium transfer drawer and streaking assembly, allows multiple culture media to be placed on the culture medium transfer drawer when streaking is required. The operator can then control the streaking assembly to streak the culture media on the transfer drawer via the main control panel, resulting in higher efficiency.

[0037] Please see Figure 1-7 The present invention provides a dual-station multi-marking head 312 linkage marking device, which includes a device housing 1, a culture medium translation drawer 2 disposed inside the device housing 1, and a marking assembly 3.

[0038] The device housing 1 has an opening on its surface that is adapted to the culture medium translation drawer 2, and the streaking assembly 3 includes several streaking parts 31 disposed inside the device housing 1 for streaking the culture medium, and a movement control device that can drive the streaking parts 31 to move horizontally.

[0039] In addition, like existing equipment, the device is equipped with a main control panel, which can control the electronic components inside the device.

[0040] To effectively achieve simultaneous streaking of multiple groups or groups of culture media, the number of culture media translation drawers 2 and streaking components 3 is at least two, and all culture media translation drawers 2 and streaking components 3 are vertically arranged and evenly distributed in the device housing 1. The surface of the culture media translation drawer 2 is provided with a groove adapted to the culture media. The culture media translation drawer 2 is connected to the inside of the device housing 1 through a slide rail. The operator can place the culture media into the groove to avoid slippage during streaking or movement of the culture media translation drawer 2, which would affect the streaking effect.

[0041] Specifically, the motion control device includes a first moving part 32 disposed inside the device housing 1, and a second moving part 33 disposed on the first moving part 32. The first moving part 32 can drive the second moving part 33 to move horizontally in the X-axis direction, and the second moving part 33 can drive the marking part 31 to move horizontally in the Y-axis direction. The first moving part 32 includes a moving guide rail 321 disposed inside the device housing 1, a moving seat 322 that can move on the moving guide rail 321, and a power source that provides the moving seat 322 with the power to move on the moving guide rail 321. The device 323 and the power device 323 can be a common motor. It, together with the moving guide rail 321 and the moving seat 322, form an electric guide rail. The second moving part 33 includes a fixed frame 331 on the moving seat 322, a guide belt 332 on the fixed frame 331, and a drive device 333 on the fixed frame 331 that can drive the guide belt 332 to move linearly on the fixed frame 331. The three together form a drive device similar to a conveyor belt structure, thereby realizing the smooth translation of multiple marking parts 31, which cooperates with the first moving part 32 to achieve accurate marking operation.

[0042] In some embodiments, considering that the scribing part 31 needs to penetrate into the petri dish to scribing, the surface of the guide belt 332 is provided with a third moving part 34. The third moving part 34 is connected to the scribing part 31 and can drive the scribing part 31 to move in the Z-axis direction. As shown in the figure, the third moving part 34 includes a connecting seat 341 provided on the guide belt 332, a movable plate 342 provided on the connecting seat 341 and connected to the scribing part 31, and a reciprocating mechanism 343 connecting the movable plate 342 and the connecting seat 341. The reciprocating mechanism 343 can drive the movable plate 342 to move in the Z-axis direction on the connecting seat 341.

[0043] Considering the overall height of the petri dish is not high, and in order to reduce the overall height of the device and reduce its volume, the reciprocating mechanism 343 includes a drive motor on the movable plate 342, a fixed plate on the output end of the motor, an eccentric protrusion on the fixed plate, and a movable clamping block on the connecting seat 341. The surface of the movable clamping block is provided with a straight groove for the eccentric protrusion to move linearly therein. The eccentric protrusion can be moved in the movable clamping block by the rotation of the motor, thereby driving the scribing part 31 to move up and down as a whole. The end of the movable plate 342 away from the drive motor is connected to the connecting seat 341 through a rotating shaft. In addition, the operator can also set limit switches on the first moving part 32, the second moving part 33, and the third moving part 34 to ensure accurate positioning during the movement.

[0044] In other embodiments, to facilitate control of the scribing degree, the scribing part 31 includes a fixed head 311 connected to the surface of the movable plate 342, a scribing head 312 disposed on the fixed head 311, and an elastic connector 313 connecting the fixed head 311 and the scribing head 312. A track limiting structure is provided between the fixed head 311 and the scribing head 312 to restrict the separation of the scribing head 312 from the fixed head 311. The operator can install different scribing ends on the scribing head 312 as needed to adapt to different scribing requirements.

[0045] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
