Cleaning method for the cleaning device of the mirror back plate

Abstract

The invention discloses a cleaning device of a back plate of a reflecting mirror. The back plate of the reflecting mirror comprises a groove type lining plate made of an SMC material, fastening nets embedded in the groove type lining plate, and two blind hole type positioning holes formed in diagonal corners of the lining plate. The cleaning device comprises a frame, positioning pins and a side edge grinding mechanism, wherein a positioning surface matched with the lining plate is formed on the upper surface of the frame; the positioning pins are arranged on the frame and correspond to the positioning holes; and the side edge grinding mechanism is arranged on the periphery of the frame and driven to move back and forth. The cleaning device is specific to the hot pressing type back plate of the reflecting mirror, the periphery of the back plate is ground and cleaned through a rotary tool, the interiors of fastening screws are cleaned through brushes, rough edges and extra materials can be effectively prevented from being generated in the production process of the back plate of the reflecting mirror, the attractiveness of the reflecting mirror is improved, and meanwhile, the situation that the extra SMC raw materials influence the strength of the back plate and the internally embedded fastening nuts is avoided.

Description

technical field [0001] The invention relates to the technical field of photoelectric mirror preparation, in particular to a cleaning device and a cleaning method for a mirror back plate. Background technique [0002] At this stage, the mirror glass used in our photothermal power generation field is about 4mm, and the glass is connected to the bracket by pasting ceramic sheets with bolts. The strength of this structure depends entirely on the quality of the glass. Therefore, the photothermal power generation mirror Some life expectancy will be affected. In addition, the reflectivity of this kind of mirror is only about 93%, which affects the efficiency of photothermal power generation. [0003] The applicant proposes a process of using SMC material thermocompression molding as the back plate of the reflector, but although the back plate of the reflector can provide high strength and sufficient toughness, the reflector will not be damaged in the harsh outdoor environment . ...
