Modular flat coating device

Abstract

The invention provides a modular flat coating device. The modular flat coating device includes a power mechanism and a coating mechanism, the power mechanism includes a first gear, a motor, and a first module frame, the first gear is connected with the motor through a motor shaft, the motor is fixed to the first module frame, and the first module frame is provide with a first assembly part; the coating mechanism includes a coating rod, a rotary table, a bearing, a second gear, and a second module frame, wherein the coating rod, the rotary table, the bearing, the second gear, and the second module frame are arranged on a clamping device, the bearing is fixed to the bottom of the second module frame and is connected with one end of a rotating shaft, the other end of the rotating shaft penetrates through the upper part of the second module frame to be fixedly connected with the rotary table, the clamping device is fixed to one side of the rotary table on the upper part of the second module frame, the second module frame is in transmission connection with the rotating shaft, the second module frame is provided with a second assembly part for being connectedg with the first assembly part in an assembled mode; and when the first assembly part and the second assembly part are connected in an assembled mode, the first gear is meshed with the second gear. According to the modular flat coating device, the problems of low coating operation efficiency and unstable coating effect of manual coating in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of biochemical instruments, in particular to a bacterial liquid coating device. Background technique [0002] Bacteria liquid coating is an important link in the process of studying microorganisms. At present, most of them are done manually by manual coating. However, the manual operation is boring, time-consuming, laborious, and highly repeatable, and it is difficult to maintain the uniformity of the same batch of flat plate coating. In order to improve the work efficiency of flat plate coating and reduce the labor intensity of the experimenters, the coating consistency of the same batch of flat plates can be guaranteed under the condition that each flat plate can be coated evenly, and it can also ensure that there will be no gap between the flat plates. The possibility of cross-infection occurs to ensure the accuracy of experimental data. Therefore, it is very important to use machines instead of manual c...

Problems solved by technology

This applicator has the following problems: (1) due to the centrifugal force, most of the bacterial liquid will accumulate around the wall of the petri dish under the centrifugal force, resulting in too dense bacteria growing into colonies, unable to count and observe the colonies feature

(2) One machine can only coat one flat plate at the same time, and the efficiency is not high
