Problems solved by technology

[0003] After the aspheric mold core is processed or precision molded for a certain number of times, it is necessary to clean the mold core to ensure its subsequent use. The existing mold core is generally cleaned by wiping the surface with alcohol, and then the mold core is cleaned. The kernels are directly immersed in a single-tank ultrasonic machine for cleaning, which will lead to a serious waste of water resources. After cleaning, it will take a long time to dry with compressed air, and the cleanliness and cleaning efficiency are not high enough, often due to the presence of tiny particles Adhesives such as impurities, white spots, and water spots adhere to the surface of the mold core and affect the quality of molding. Therefore, it is necessary to optimize the cleaning device and cleaning process

Embodiment approach

[0024] Such as Figure 1-3 As shown, the optical glass aspheric lens mold core cleaning device of the present invention includes a clamping device, a cleaning feeding rack, a multi-slot ultrasonic automatic cleaning machine and a control system. Among them, the clamping device includes a mold core clamping disc 1, a bracket 2 and a chute 3, and the length and width of the mold core clamping disc 1 can be determined according to the inner groove size of the multi-groove ultrasonic automatic cleaning machine; The chuck 1 is provided with a number of die core holes 11 for placing die cores. The die core holes 11 can be arranged at equal intervals. The inner diameter of the die core holes 11 is determined according to the size of the cylinder of the aspherical die core. The conventional size is φ3-50mm; the cross-section of the bracket 2 is a right triangle, and the inclined surface 21 maintains a certain inclination angle. Through multiple tests, the inclination angle α of the in...

Embodiment

[0035] Example: Taking a Φ33mm mold core as an example, since the mold core is a flat-convex surface, a small connection R (about 0.001mm) will be formed between the two surfaces, and there will be polishing paste and a small amount of oil stains, high-temperature glass bonding Substances, if the surface is just wiped with a cotton swab soaked in acetone, dirt will still remain inside the connection R. After coating, the dirt will be sandwiched between the mold core and the film layer, and it is easy to form a stripping film after high pressure and high temperature of pressing, reducing the service life of the film layer.

[0036] First, use cotton swabs to pre-clean the surface of the mold core with alcohol and acetone with a weight ratio of 1:35, put the mold core into the mold core chucking plate 1, and then guide it through the chute 3 and fix it on the bracket 2, and then place the whole The clamping device is fixed on the cleaning loading rack through the positioning gro...

Abstract

The invention provides an optical imaging aspheric lens mold core cleaning method with high cleaning cleanliness. The optical imaging aspheric lens mold core cleaning method comprises the following steps that the surfaces of to-be-cleaned mold cores are pre-cleaned; a control system controls a cleaning feeding frame fixedly provided with a clamping device to automatically enter a cleaning agent prepared in a first tank, soft water in a second tank, pure water in a third tank, an IPA reagent in a fourth tank and a fifth tank to be dried. According to the optical imaging aspheric lens mold corecleaning method, a fixed cleaning disc is directly filled with the to-be-cleaned mold cores, the surfaces of the mold cores are cleaned through different cleaning agents and processes in all grooves of an ultrasonic cleaning machine, the cleaning cleanliness and efficiency are improved through automatic walking and step-by-step cleaning, and the problem that in the cleaning process of the mold cores, tiny particle impurities, white points, water spots and other stickers are attached to the surfaces of the mold cores is solved.

Description

technical field [0001] The invention relates to a method and a device for cleaning an aspherical lens mold core, in particular to a cleaning method and a device for aspherical high-precision surface-shaped lens mold cores. Background technique [0002] With the increasing application of aspheric optical glass in the field of imaging, the demand for high-performance aspheric lenses is becoming more and more urgent, so the requirements for the appearance quality of aspheric lenses are also getting higher and higher. Ultra-precision compression molding is the best method for manufacturing aspheric lenses. It can efficiently and high-quality mass-manufacture glass aspheric lenses. This method can repair microwave scratches and spots on the surface of glass preforms during the forming process, and can also perfectly reproduce them. Spots, tiny particles, and dirt on the surface of the mold core affect the appearance quality of the aspheric lens, so the requirements for the surfac...
