The invention discloses a liquid level detection method-temperature control method for lens monomer filling. The method comprises the following steps that 1, a mold for being loaded with lens monomersis fixed on a supporting device; 2, one end of a temperature control probe is connected with a temperature control signal detector through a signal line, the other end of the temperature control probe is a free end, the free end of the temperature control probe is suspended in a filling port of the mold, and the distance between the free end of the temperature control probe and the filling port is 0.1-0.5 mm; and 3, when the lens monomers are injected into the mold, the temperature control signal detector receives a signal of whether the temperature control probe is in contact with the lens monomers or not, and whether the lens monomers injected into a mold cavity fill the mold cavity or not is judged through the change of an electric signal on the temperature control signal detector. According to the method, the automation degree of lens processing can be improved, the quality of a lens can be improved, and the labor intensity can be reduced.
Description
technical field [0001] The invention relates to a liquid level detection method for lens monomer filling-temperature control method. Background technique [0002] In the production process of resin lenses, the molds are first cleaned, and then the cleaned molds are combined in different ways according to the requirements, and then the lens monomer is loaded, that is, the resin is pre-polymerized according to a certain formula to reach a certain viscosity, and then obtained after vacuum degassing. The lens monomer is currently manually injected into the mold cavity of the assembled glass and filled with the glass. The filled mold is placed in an oven. After a thermal cycle, the lens monomer is cured. After opening the mold, semi-finished lenses are produced, and the semi-finished lenses are processed into finished lenses after subsequent processing. [0003] At present, in the process of processing, the lens monomer is manually injected into the glass cavity. During the fill...
