Embodiment 1

[0050] Such as figure 1 As shown, the self-adaptive beam current nuclear pore membrane automatic production device provided by this embodiment includes a data detection system 1, a beam current device 2, a control computer 3, and a film winding machine 4;

[0051] The data detection system 1 includes a number of beam detectors 11 and a beam collection system 12; the beam detector 11 is used for online real-time detection of the beam size and position emitted by the beam device 2, and the beam collection system 12 is used for collecting the beam detector 11 beam signal;

[0052] The control computer 3 is used to obtain the data of the beam collection system 12 for fitting and send instructions to the film winding machine 4 so that the rotation speed of the film winding machine 4 matches the beam current size, so that the nuclear pore film production is always in the optimal state. Among them, the optimal state means that the production efficiency of the nuclear pore membrane is at t...

Embodiment 2

[0064] This embodiment details the automatic production method of an adaptive beam current nuclear pore membrane, which includes the following steps:

[0065] S1. The components of the production equipment are ready for normal production;

[0066] S2. During the production process, the beam detector 11 detects the beam current intensity and position signals emitted by the beam device;

[0067] S3. The beam current acquisition system 12 collects beam detector data and sends it to the control computer 3;

[0068] S4. The control computer 3 receives the beam current acquisition system data, performs fitting analysis and calculation, and controls the film winding machine 4 so that the rotating speed of the film winding machine 4 matches the beam current size to ensure that the nuclear pore film production is always in the expected state .

[0069] Further, the method also includes a step for correcting the magnitude of the current and the magnitude of the frequency output by the beam curre...

Description

Technical field [0001] The invention relates to a self-adaptive beam current automatic production device and method for nuclear pore membranes, and relates to the technical field of nuclear pore membrane irradiation production and manufacturing. Background technique [0002] Nuclear porous membrane is the most precise microporous filtration membrane in the world. It is a porous plastic film with densely packed small holes, each of which has the same shape and size. There are many specifications for nuclear pore membranes, the thickness of the membrane ranges from 5 microns to 60 microns, the pore diameter ranges from 0.2 microns to 15 microns, and the hole density ranges from 1-10 to the 9th power per square centimeter. [0003] Nuclear porous membranes usually use heavy ion perforation provided by high-energy accelerators. Heavy ion perforation is the most critical part of the nuclear porous membrane production process. Few existing technologies have heavy ion accelerators suitab...
