Problems solved by technology

[0004] 1. The L-shaped structure cannot be applied to culture dishes of different sizes. When the size of the culture dish changes, it is necessary to replace the L-shaped coating structure of different corresponding sizes; 2. When the surface of the medium is uneven and undulating, the L-shaped contact is a line. There are problems of uneven smearing and missing coating; 3. When the surface of the medium is uneven and undulating, the L-shaped coating structure is applied evenly to fit the surface of the medium, and the downward pressure will increase, which will easily cause the surface of the medium to be scratched ;4. Due to the poor linkage control effect of the mobile device and the petri dish in the L-shaped coating structure, it is easy to cause the coating to exceed the range, and the coating mobile device moves too fast or too slowly, resulting in uneven coating and missing coating.

Embodiment Construction

[0023] The specific implementation of the coating rod device and the petri dish coating method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] See attached figure 1 , the structure of the coating rod and the attachment of the patent CN202010138005.6 Figure 4 The structure is similar to that in the disc-shaped main body 1 below it, and a cross-shaped rib 2 is arranged on the lower surface of the main body 1. The center crossing position of the cross-shaped rib 2 is hollow, and the outer end of the cross-shaped rib 2 is connected to the edge of the main body 1. Get some distance away.

[0025] The supporting driving rotating part of the coating rod is driven to rotate, and the culture medium in the culture dish 5 is coated.

[0026] See attached figure 2 , When the surface of the culture medium is uneven and undulating, if the downward pressure is insufficient, the uniform smearing on the surface of the cult...

Abstract

The invention relates to the technical field of laboratory automation, and discloses a coating rod device, which comprises a coating rod and a rotation driving part, the coating rod is installed on the rotation driving part, the rotation driving part drives the coating rod to rotate, the coating rod comprises a disc-shaped main body, the lower surface of the main body is provided with a cross-shaped convex edge, and the cross-shaped convex edge is arranged on the lower surface of the main body. The central cross position of the cross-shaped rib is hollow, and the outer end of the cross-shaped rib is a certain distance away from the edge of the main body. The invention further discloses a coating method. The culture medium coating device is high in adaptability and uniform in coating in the culture medium coating process.

Description

technical field [0001] The invention relates to the technical field of laboratory automation, in particular to a coating bar device and a method for coating a petri dish. Background technique [0002] When cultivating microorganisms through a petri dish, the sample on the medium is coated. In the automated microbial device, the coating rod is reciprocated on the surface of the medium to evenly distribute the sample on the medium. [0003] The patent applied by the applicant earlier: microbiological detection petri dish coating device and coating control method (application number: CN202010138005.6), the coating rod disclosed in it has an L-shaped structure, and the L-shaped structure has the following problems: [0004] 1. The L-shaped structure cannot be applied to culture dishes of different sizes. When the size of the culture dish changes, it is necessary to replace the L-shaped coating structure of different corresponding sizes; 2. When the surface of the medium is uneve...
