Description

Technical Field

[0001] The invention relates to the technical field of film sealing, and in particular to a full-automatic film sealing instrument. Background Art

[0002] Laboratories generally seal porous sample plates for subsequent experimental operations. Conventional sealing methods are divided into cold sealing and hot sealing. However, cold sealing operations are relatively cumbersome and require certain skills and experience to use correctly. The commonly used hot sealing equipment on the market is either too single-function and requires manual placement of the film, which has the risk of contaminating the solution and cannot meet the use scenarios that require aseptic operation. Products that meet the requirements of fully automatic operation are mostly too complicated in design, require repeated testing and adjustment, have low reliability, and are a challenge for operators to replace the required film every time. In addition, the equipment is expensive, which increases the cost of use.

The application has the effect of reducing the possibility of manual contact with the deep-well plate during the film sealing process of the deep-well plate, and improving the safety of the deep-well plate sealing. The device needs to repeatedly manually place the film on the film-carrying mechanism each time it seals the film, which is easy to cause contamination to the film, and the operation is not simple.

In this case, the heating plate does not need to be heated.
