Problems solved by technology

However, the current direct microscopic examination method is limited to manual operation, and there is no automatic somatic cell analyzer based on this method on the market at home and abroad, and there is no microscope detection device suitable for the direct microscopic examination method milk somatic cell / bacteria automatic counter
Manual operation will not only cause low work efficiency, but also inevitably produce human error

Embodiment Construction

[0016] Refer to attached picture. It is provided with a microscope objective lens 1 and a digital camera 2 for photographing milk samples on a glass slide through the objective lens. The microscope objective lens and the digital camera are installed on the lens barrel 3. The microscope detection device is provided with a lens barrel up and down adjustment drive mechanism. The microscope detection device is provided with a transmission mechanism and a drive mechanism thereof for sending the slide glass 100 to the detection area below the objective lens and out of the detection area under the objective lens. mechanism.

[0017] The control device for adjusting the driving mechanism of the lens barrel up and down and the driving mechanism of the aforementioned transmission mechanism includes a computer, a single-chip microcomputer, a photoelectric sensor or a contact switch.

[0018] The up and down adjustment drive mechanism of the lens barrel includes a stepping motor 4, a hel...

Abstract

The invention discloses a self-counting microscopic detecting device, which comprises the following parts: microscopic objective lens and digital cam on the draw tube, upper-lower adjusting driving mechanism in the draw tube, driving and transmitting mechanism on the lower end of objective lens and moving out mechanism of glass-carrying piece from transmitting mechanism. The focusing method of microscope comprises the following steps: setting error parameter of brightness gradient value; shooting milk sample image on the glass-carrying piece; adjusting objective lens of microscope; shooting milk sample image on the glass-carrying piece again; comparing brim brightness gradient value of two images; affirming focus; focusing.

Description

technical field [0001] The invention belongs to a milk product somatic cell / bacteria counting instrument, in particular to a microscope detection device and a microscope focusing method in an automatic milk somatic cell / bacteria counting instrument based on the direct microscope inspection method. Background technique [0002] Dairy somatic cell automatic analyzer is an instrument for automatic counting of somatic cells in dairy products and automatic analysis of the counting results. After dairy cows are infected with mastitis, the most obvious and direct symptom is the increase of somatic cell count (SCC for short) in the milk. Mastitis will not only reduce the milk production of dairy cows, but also lead to a decline in the quality of dairy products. Therefore, for the detection of SCC in milk, on the one hand, it can detect the quality of milk and ensure the nutritional value of dairy products; Reduce economic loss. [0003] The dairy somatic cell analyzers currently ...
