Abstract

The invention discloses an automatic mold opening device for optical lenses, which includes a frame, a conveying unit, a heating unit, a cooling unit, and a controller. The conveying unit includes a conveyor belt horizontally arranged on the frame. The heating unit includes an oven for heating, the cooling unit includes a cooling box for cooling, the conveyor belt passes through the oven and the cooling box in turn, the delivery unit, the heating unit, and the cooling unit are connected to the controller. The conveying unit is controlled by the controller to transport the template and the lens taken out of the curing furnace to the heating unit for heating, and then to the cooling unit for cooling. After the lens and the mold are alternately cooled and heated, the deformation of the lens and the mold are separated after cooling. , to achieve automatic mold opening, without manual mold opening, improve production efficiency, automatic mold opening, reduce bumps and scratches on the lens, and improve the pass rate of products.

Description

technical field [0001] The invention relates to the technical field of lens manufacturing equipment, in particular to an automatic mold opening device for optical lenses. Background technique [0002] Resin lens is an optical lens made of resin. Because of its significant advantages such as light weight, strong impact resistance, and good light transmission, it is widely manufactured and used. At present, molds for making resin lenses usually adopt two molds (one A mold and one B mold) to manufacture resin lenses by casting. After the resin lens is cured, a mold opening process is required. At present, most manufacturers use the traditional process to open the mold. The traditional mold opening process mainly uses a manual release device to open the mold. The manual release device mainly uses the top block to impact and squeeze the lens to deform the lens. The mold is separated from the lens. In the process of using the release device, due to the uncertain factors of the...
