The ICMOS camera takes an image intensifier as a core, and realizes the gain of weak light signals by controlling the light-electricity-light-electricity conversion through pulse high voltage.
The core component of the image intensifier is a micro-channel plate, the structure of which is shown in fig. 1-2, the micro-channel plate (MCP) is a two-dimensional electron multiplier device composed of thousands of hollow glass capillaries which are closely arranged in parallel with each other, each micro-hole in the plate is a channel, namely a miniature electron multiplier device, a single channel can only be used for detecting electrons, neutrons and the like, X-rays, r-rays, particles with energy and the like, and the two-dimensional electron multiplier array is used for detecting and amplifying a photoelectric image, and the more channels in the plate (each channel is one pixel), the more pixels are, and the clearer the image is.
When a batch of microchannel plates are produced and formed, each microchannel plate is required to be packaged in the process, namely, a layer of adhesive film is coated on the top surface and the bottom surface of the microchannel plate, and the adhesive film prevents external dust from entering the channels of the microchannel plate, and the schematic structural diagram of the microchannel plate coated with the adhesive film 2 is shown in fig. 3-4.
The operation method for packaging the microchannel plate in the workshop comprises the following steps:
s1, taking out a micro-channel plate 1, and horizontally placing the micro-channel plate on a workbench;
s2, placing a layer of adhesive film 2 on the top surface of the microchannel plate 1 by a worker, and then driving down the outer edge of the adhesive film 2, namely turning down the outer edge of the adhesive film 2 to form a turned-over edge 3;
s3, a worker holds the heating rod 4 to enable the heating rod 4 to move around the circumference of the flanging 3, heat generated by the heating rod 4 is transferred to the flanging 3 in the moving process, and after the flanging 3 is heated, the heating rod is heat-sealed on the outer cylindrical surface of the microchannel plate 1, so that a layer of adhesive film 2 is coated on the top surface of the microchannel plate 1;
s4, a worker turns over the whole microchannel plate 1 by 180 degrees, and repeats the operations of the steps S2-S3, namely, a layer of adhesive film 2 is coated on the bottom surface of the microchannel plate 1, so that the film coating of the microchannel plate 1 is finally realized, namely, the packaging of the microchannel plate 1 is realized;
s5, repeating the operation in this way, so that the packaging of a batch of micro-channel plates 1 can be realized.
However, although the operation method in the shop can realize the packaging of the microchannel plate 1, the following technical drawbacks still exist in actual operation:
I. in step S3, when the heating rod 4 heats the flange 3, the middle material of the adhesive film 2 is warped and deformed, so that the top material of the adhesive film 2 is not completely adhered to the top surface of the microchannel plate 1 (and the adhesive film 2 is required to be completely adhered to the top surface of the microchannel plate 1 in the process), thereby reducing the quality of the coating, and having the technical defect of low coating precision.
II. In the whole laminating operation, only one layer of adhesive film 2 can be coated on the top surface of the microchannel plate 1, and then one layer of adhesive film 2 is coated on the bottom surface of the microchannel plate 1, which clearly increases the laminating process, increases the laminating time, and further greatly reduces the laminating efficiency of the microchannel plate. Therefore, there is a need for a film laminating device and method that greatly improves the film laminating accuracy and the film laminating efficiency of the microchannel plate.
