Crosslinking agent titration nozzle transfer device, titration device and automatic sealing equipment

Abstract

The invention relates to a cross-linking agent titration nozzle transfer device, a titration device and automatic sheet sealing equipment. The transfer device comprises a motor, a rotating arm and a nozzle; one end of the rotating arm is fixed on a motor shaft of the motor, a bearing of the motor shaft is provided with a fixed first synchronizing wheel, and the other end of the rotating arm is provided with a rotatable second synchronizing wheel; the sprayer is fixed to a second synchronous wheel, the second synchronous wheel is connected with the first synchronous wheel through a synchronous belt, a motor shaft drives a rotating arm to rotate so as to transfer the sprayer back and forth between the first station and the second station, and the rotating arm rotates relative to the first synchronous wheel so that the synchronous belt can drive the second synchronous wheel to rotate; and the second synchronizing wheel is driven by the rotating arm to do planet wheel follow-up motion, so that the spray head and the second synchronizing wheel follow-up motion to generate angle change relative to the rotating arm, and the angle change counteracts the rotating angle of the rotating arm to enable the spray head to be always kept in a vertically downward posture. The device realizes efficient, stable, accurate and high-repeatability nozzle transfer operation and titration operation.

Description

technical field [0001] The invention relates to automatic sealing processing equipment for biological tissue sample slices, in particular to a cross-linking agent titration nozzle transfer device, a titration device and automatic sealing equipment. Background technique [0002] Pathological sectioning in biological tissue sample slices is a widely used method. Generally, a certain size of lesion tissue is taken, and pathological sections are made by histopathological methods. Usually, the lesion tissue is embedded in paraffin blocks, and sliced ​​with a microtome. Cut into thin slices, stain with hematoxylin-eosin (H-E), further examine the lesion with a microscope, observe the occurrence and development of the lesion, and finally make a pathological diagnosis. The automatic sealing processing technology of biological tissue sample slices is an important step in the automatic dyeing, drying and sealing process of biological tissue samples, and it is also an indispensable ste...

Problems solved by technology

The traditional sealing machine performs physical straight-line hard pressing when taking the cover glass to seal the slide, which is easy to generate air bubbles, which will make the number of air bubbles in the sealed slide relatively large, which will affect the subsequent observation and formation. The storage quality and storage time limit of slices

[0004]The full automation of the traditional sealing machine is not very complete, and it cannot be completely automated and unmanned from the whole process of drying, dyeing, drying and sealing. A part of the function will always be separated and processed separately

[0005]The design of the traditional sealing machine is that the slides are arranged in a rectangular array on the tray, and it is necessary to separate the slides for staining, sealing, etc. During the operation steps, the slide glass module is basically fixed, and the cover glass module is moved and position corrected. This kind of work and movement method has high requirements for the movement device, especially for the motion control line. The strength requirements are relatively high, which increases the tangible cost
