Cleaning device of infrared ray cut off filter for small size optical instrument

摘要

The present invention relates to a cleaning device for an infrared cut filter used in a small optical device, in the surface cleaning step of a product for cleaning both surfaces of the product before the completion of the infrared cut filter in the manufacturing process of the infrared cut filter, In the related art, as a worker picks up products one by one using a hand or a tool and performs a cleaning operation, the work takes a long time, and workability is also poor, resulting in a decrease in productivity.;Therefore, the present invention provides a surface inspection step of the disc, a coating film inspection step of the disc, a primary cutting process of the disc, a secondary cutting process of the disc, a step of confirming the dimensions of the product, a surface cleaning step of the product, In manufacturing the finished infrared cut filter through the surface inspection step of the product,;A pair of fitting grooves 111 and 121 are formed on the surface to maintain a constant interval in a straight line shape so as to be used in the surface cleaning step of the product, and a pair of holes 112 and 122 are formed at one side and the other edge thereof. The plate 110, 120 and the cleaning device consisting of a fixing pin 200 is fitted into the holes 112, 122 of the plate 110, 120, through the surface cleaning step of the product When cleaning both sides of the product, one surface of the product 300 is cleaned in a state in which a plurality of products 300 are inserted into the respective fitting grooves 111 of the plate 110, and then the top surface of the plate 110. Overlay the other plate 120 so that the fitting grooves 111 and 121 face each other while facing each other, and at this time, the fixing plate 200 in the holes 112 and 122 of the matching plate 110 and the other plate 120. ) And then flip the plate 110 and the other plate 120 overlaid together and then the fixing pin 200 and the top After removing the plate 110, the surface of the other side of the product 300 moved to the fitting groove 121 of the other plate 120 can be cleaned immediately, so that a large number of products 300 can be quickly and easily cleaned. Overall workability and productivity can be further improved.
