Cover glass sucking and pressing sealing device and automatic sealing equipment

Abstract

The invention relates to a cover glass sucking and pressing sealing device and automatic sealing equipment, and the device comprises a first suction head, a second suction head, a suction head platform and a reciprocating transfer mechanism, and the first suction head and the second suction head are fixed at the bottom of the suction head platform; the reciprocating transfer mechanism is coupled to the suction head platform to transfer the suction head platform back and forth between a cover glass suction station and a pressing and sealing station, and the first suction head and the second suction head are triggered on the corresponding stations to start air suction so as to suck the cover glass or stop air suction so as to release the cover glass, when the suction head platform is in a middle state between a suction action and a sealing piece pressing action, the suction head platform keeps an inclined state to enable the first suction head to be lower than the second suction head, and when the suction head platform is in an operation state of a downward suction action or a downward sealing piece pressing action, the first suction head is firstly jacked upwards to enable the suction head platform to gradually tend to be horizontal. Therefore, the second suction head is delayed to participate in the suction action or the sealing piece pressing action relative to the first suction head, and the effect of preventing bubbles from being generated in the piece covering process to the maximum extent is achieved.

Description

technical field [0001] The invention relates to automatic sealing processing equipment for biological tissue sample slices, in particular to a cover glass absorbing and pressing sealing 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 step. To store slices for...

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

[0003] The automaticity of the traditional sealing machine is not very complete, and it cannot be fully automated and unmanned from the whole process of drying, dyeing, drying and sealing, and some functions will always be separated and processed separately

[0004] The design of the traditional sealing machine is that the slides are arranged in a rectangular array on the tray, and when performing steps such as staining and sealing that need to be operated on individual slides, the slide module is basically fixed. It does not move, and the cover glass module moves and corrects its position. This kind of work and movement has high requirements for the movement device, especially for the strength of the motion control line, which increases the tangible cost.
