Problems solved by technology

After the hardening liquid is sprayed on the surface of the resin lens, it needs to be heated to make the hardening liquid quickly condense on the surface of the resin lens to form a protective film; Copper tubes are installed, and the copper tubes are connected to the fan; during use, the temperature in the oven is uneven, especially the temperature of the lens placed on the bottom layer cannot be circulated here, and the baking time is longer than other lenses

Abstract

The invention discloses a primary curing oven for lenses. The primary curing oven of the lens is characterized in that air inlets (6) are formed in the positions, in contact with the left side vertical surface and the right side vertical surface of a box body (1), of a box door (3) after the box door is closed, the edge of each air inlet (6) is provided with a flange which extends outwards, the positions, corresponding to the air inlets (6), of the left side vertical surface and the right side vertical surface of the box body (1) are provided with air outlets (7), hinged baffle plates (8) arearranged on the inner sides of the air outlets (7), the air outlets (7) can be shielded through the baffle plate (8), and when the box door (3) is closed, the flanges of the air inlets (6) push away the baffle plates (8), so that the air inlets (6) communicate with the air outlets (7), and hot air in a circulating air duct enters the box door (3), and is discharged into the box body (1) through aplurality of air holes (9) formed in the box door (3). The primary curing oven is simple in structure and convenient to use, the temperature inside the box body is uniform, so that the drying time ofthe lenses is effectively guaranteed to be consistent.

Description

technical field [0001] The invention relates to the technical field of resin lens production, in particular to a lens primary curing furnace. Background technique [0002] At present, the resin lens will be hardened to form a protective layer on the inner and outer surfaces of the lens, so as to increase the corrosion resistance and friction resistance of the resin material and prolong the service life. After the hardening liquid is sprayed on the surface of the resin lens, it needs to be heated to make the hardening liquid quickly condense on the surface of the resin lens to form a protective film; There are copper pipes, and the copper pipes are connected to the fan; during use, the temperature in the oven is not uniform, especially the temperature of the lens placed on the bottom layer cannot be circulated here, and the baking time is longer than other lenses. Contents of the invention [0003] Aiming at the above-mentioned defects, the object of the present invention ...
