Description
Technical Field
The invention belongs to the field of fixing of metal grids of optical systems, and particularly relates to a fixing device and a fixing method of a metal grid.
Background
The metal grid is mainly used for beam splitting or beam combination, has higher reflectivity, plays an important role in an optical system, has a larger influence on the polarization state of a light beam, influences the measurement structure of a polarization interferometer, and plays an irreplaceable role in a tokamak system.
Because of the high cost (8000 yuan/piece, 12 inches by 12 inches) and the susceptibility of the metal grid to breakage, it is important to secure the metal grid to the grid frame in a flat and secure manner. The traditional method is to attach one corner of the metal grid to one corner of the grid frame and fix the metal grid by glue, straighten one side of the grid by hand and attach the grid frame by hand, and then fix the side by glue dripping. After the edge is completely fixed, the grid mesh is attached to the grid mesh frame by the same method, then glue is dripped for fixing, and the rest edges are sequentially fixed.
The whole process is to straighten the grid net by hands, which is easy to cause human factors such as: the hands shake greatly, which breaks the metal grid. In addition, the quality of the manual wire-mesh is also compromised, being prone to "straightening out", i.e. not in one plane, etc. The traditional method is time-consuming and labor-consuming, and the metal grid is easier to break. Accordingly, there is a need for an apparatus and method for efficiently securing a metal grid to solve the problem.
