Description
Technical Field
The application relates to the technical field of lens manufacturing equipment, in particular to automatic release equipment for optical lenses.
Background
The two-sided structure (a and B mold) of the once cured semi-finished product is called glass mold, the middle is transparent optical lens, and the process of separating the mold and the optical lens from the whole discharged furnace is called release separation of the lens.
At present, the release method of most manufacturers is that the lens, the A mold and the B mold are taken out of the curing oven once manually, and the sealing adhesive tape is torn off; then, cutting cracks in the gaps between the optical lens and the A and B moulds; then putting the integral structure into tap water for cooling and deforming; then separating by combining with a manual separator (such as compressed air blowing accelerated separation); and finally, finishing off-line work of the optical lens and the A and B moulds.
The working principle is as follows: after tap water is cooled, rapid temperature difference (between 20 and 60 ℃) is generated, meanwhile, the expansion rates of the glass mold and the optical lens are different, and the optical lens is separated out due to different size deformation. As the combined specification of the optical lens and the A and B molds reaches thousands of specifications, the optical lens and the A and B molds need to be respectively corresponding to different temperatures and time to achieve the release action, the temperature of tap water is uncontrollable, most optical lenses and the A and B molds cannot be released in the actual production process, a manual release device needs to be added, and the optical lens and the A and B molds are impacted and broken through pure mechanical action. Therefore, in the above-mentioned release process, it is very important to set or control the release temperature for the expansion rate of different optical lenses.
The existing optical lens release separation steps are as follows: the operating personnel carries a product to the station of tearing the sticky tape from curing oven in, and operating personnel tears the sticky tape from glass and puts into the frame, puts into hot-water tank and cold water tank with whole frame again and carries out cold and hot alternation, then takes out glass from the frame, and the artifical simple and easy type ware of leaving type of utilization of unseparating is released: the top block is used to impact the lens and the a-mode is separated from the B-mode by deformation of the lens. However, the above-mentioned release separation technology causes the following problems in the production and manufacturing process:
the lens appears colliding with the fish tail in many times of handling, and the defective rate is high. The lens is scratched mainly because after the lens is separated from the mold, the lens is scratched by a sharp edge which slides relative to the lens or by debris entering between the mold and the lens. This scratch is typically caused by three conditions: because the temperature of the product just after the product is discharged out of the curing oven is about 70 ℃, a small part of lenses and glass can be separated when the product is in contact with cooler air, and the vibration in the carrying process can generate sliding; most products are separated from each other through the hot water tank and the cold water tank, and can slide in the conveying process; slippage can occur during handling.
Based on the principle of expansion with heat and contraction with cold in the prior art, the invention optimizes the process, solves the problem with pertinence, realizes more refined production, and finds that different products (such as myopia glasses and presbyopic glasses) utilize different expansion with cold temperature differences through long-time production practice, and the lenses can be easily separated only by proper temperature differences. At present, most manufacturers put the product into a water tank with constant temperature, and the temperature cannot be controlled in the process, so that the most suitable release temperature difference of the product cannot be utilized, and the release rate is reduced. In order to improve the release rate, the mold is released in the mode of the mold releasing device, and the damage rate of the mold is increased.
Therefore, the existing optical lens release equipment has the advantages of high damage rate of a mold in the use process, waste, large occupied area, waste of water sources and the like.
