The application discloses a UV dispensing curing machine and a curing method, and belongs to the technical field of dispensing machines. The machine comprises a dispensing box, a lifting assembly is arranged in the dispensing box, a dispensing structure for dispensing is arranged on the outside of the lifting assembly, the dispensing structure has a primary curing function, and two curing chambers for increasing the curing degree are arranged on the side wall of the dispensing box. According to the application, the depth of the glue column into the glue pipe can be controlled by controlling the expansion range of the power film, and the glue output of the glue pipe can be controlled, so that the component can be coated more accurately. When the glue column moves upward in the glue pipe, the inside of the glue pipe is in a negative pressure state, the glue in the glue pipe is sucked at this time, so that the glue liquid cannot flow out of the glue outlet of the glue pipe, and the parts on the upper end of the component are prevented from being polluted by the excess glue liquid. Meanwhile, the glue liquid can be cured more thoroughly through twice curing at different times.

The present invention discloses a low dielectric constant filter membrane based on biological enzymes. The preparation method includes drying the low dielectric constant filter membrane, dropping biological enzymes onto the surface of the dried filter membrane and then freeze-drying. After the moisture has completely evaporated, the low dielectric constant filter membrane based on biological enzymes is obtained. At the same time, the present invention also discloses the application of the low dielectric constant filter membrane based on biological enzymes in a waveguide gas sensor. After fixing the low dielectric constant filter membrane based on biological enzymes on the resonance window of the resonator in the waveguide gas sensor, the sensor is assembled and tested. By using a filter membrane with a small volume that is convenient for installation and disassembly, the present invention is conducive to repeatedly testing the same sample multiple times, has good reusability, and the low dielectric constant filter membrane based on biological enzymes has good air permeability, which can enable the enzymes to fully contact with the gas, further improving the sensitivity of the sensor.
