Problems solved by technology
In the production process of the nuclear pore membrane, there is a problem that the roll membrane is entangled due to the uneven tension
If the film winding phenomenon is not discovered in time, it will become more and more entangled, which will not only waste raw materials, but also affect the production progress, and more seriously, damage the life of the machine

The invention relates to a video linkage control device for the production of nuclear pore membranes. The device includes a film rolling machine, a camera, a video data acquisition device and a control computer; The device is used to capture the running state of the irradiated film on the reel; the video data acquisition device is used to collect the video data captured by the camera; the control computer is used to analyze and process the collected video data and identify the reel The running state of the upper irradiated film, if there is a winding state of the reel, send a signal to the film machine for emergency stop. The invention can carry out automatic error correction processing on the winding of the roll film, effectively prevent the winding of the roll film, ensure the production progress and prolong the service life of the machine.
Description
technical field [0001] The invention relates to an automatic error-correcting nuclear pore membrane production video linkage control device, and relates to the technical field of nuclear pore membrane irradiation production. Background technique [0002] Nuclear pore membranes are the most precise microporous filtration membranes in the world. It is a porous plastic film with densely packed small holes, each of which has the same shape and size. The nuclear pore membrane has many specifications, the membrane thickness ranges from 5 microns to 60 microns, the pore diameter ranges from 0.2 microns to 15 microns, and the pore density ranges from 1-10 to the 9th power per square centimeter. [0003] Nuclear pore membranes are generally perforated by heavy ions provided by high-energy accelerators. Heavy ion perforation is the most critical part of the production process of nuclear pore membranes. Only a few countries in the world have heavy ion accelerators suitable for the pr...
