Abstract

The invention provides a bonding method for a support pad of a large-aperture reflecting mirror, relates to the field of large-aperture reflecting mirrors and solves the problems that the reflecting mirror cannot be correctly placed once, the position of the reflecting mirror cannot be adjusted and glue thickness is uncontrollable with a conventional bonding way. According to the method, the position of the support pad is determined by a laser tracker, a fish tape is inserted between the support pad and the reflecting mirror to determine the thickness of a glue layer, glue mixed by a glue gun is smeared uniformly to the support pad, then the position of the support pad is adjusted by a positioning tool until requirements are met, the support pad is left to stand for a week, the positioning tool is removed after glue curing, and bonding of the support pad is completed. The position precision of the support pad is adjustable and controllable, the thickness of the glue layer is controllable, the bonding is firm, the position precision and the bonding strength both meet use requirements, and the method can be applied to bonding and fixing of the support pads on the back and side surface of any large-aperture reflecting mirror.

Description

technical field [0001] The invention relates to the technical field of large-diameter reflectors, in particular to a bonding method for supporting pads of large-diameter reflectors. Background technique [0002] When the diameter of the mirror is small, the peripheral support or central support is generally used to meet the requirements of the mirror surface shape. However, when the diameter of the reflector increases, the weight of the reflector can reach hundreds of kilograms or even more than one ton. At this time, multiple points of support on the back and side are required. Support pads connect the mirrors to the complex support structure. The bonding of the support pad must not only ensure the correct bonding position and sufficient bonding strength, but also ensure that no additional bonding stress will be generated. During the bonding process, the roughness and cleanliness of the bonding surface, the thickness of the adhesive layer, Factors such as the choice of gl...
