Abstract
Description
Technical Field
[0001] The utility model relates to a fixture for special optical lens materials, belonging to the technical field of lens coating. Background Art
[0002] High-precision industrial lenses are widely used in technical fields such as electronic information, aerospace, automobile manufacturing and security, and play a positive role in promoting the development of the manufacturing industry. In the production process of high-precision industrial lenses, the obtained lenses need to be processed through multiple processes to obtain high-precision products of specified specifications. At present, it faces challenges such as the growth in the use of optical lenses, advanced vision correction technology, low industry concentration, high price markups in the middle links, increased labor costs, and uneven qualifications of practitioners. Due to the large differences in the expansion coefficients of new materials, the current situation where the gaps between coating jigs and different lens materials are the same can no longer adapt to current development. Materials with smaller expansion coefficients may result in loose fits between lenses and coating jigs, resulting in shaking. Materials with larger expansion coefficients may result in tight fits. In severe cases, the lenses may even expand due to heat and are squeezed by the jig during the coloring process, causing them to explode. Utility Model Content
[0003] The utility model solves the technical problems existing in the prior art, thereby providing a fixture for special optical lens materials.
[0004] The existing technical problems are solved by the following technical solutions: a jig for special optical lens materials, the end face of the jig chassis has four locating pins that match the jig cover 1, the jig cover has four locating holes, the four locating holes are respectively connected with the four locating pins of the jig chassis, the jig cover has upper grooves for placing lenses, the jig chassis has lower grooves for placing lenses, and the end face of the jig chassis has a cross-shaped heat dissipation groove.
[0005] The jig chassis is placed on the coating umbrella in the coating machine. The depths of the upper lens groove and the lower lens groove are 1.07mm respectively. The thicknesses of the jig cover and the jig chassis are 3mm respectively. The gap between the jig chassis and the jig cover is 0.3mm. The outer diameter of the lens plus the gap is 20.55mm in diameter. The coating range is 20mm in diameter. The outer diameter of the lens is exposed.
[0006] The advantages of the present invention are: compared with the previous coating jig, the present invention adds a heat dissipation slot, which can effectively dissipate heat and reduce weight, and plays an important role in preventing the lens from bursting with the coating jig under a heated environment. In addition, the present invention breaks the original design habit of using the same gap with lenses of different materials, but adjusts the size of the lens placement slot according to the expansion coefficient of the lens material, which plays a decisive role in preventing the lens from bursting with the coating jig under a heated environment. The heat dissipation slot is added to reduce weight and dissipate heat. The size of the lens placement slot is designed according to the expansion coefficient of the lens material, which effectively avoids the phenomenon of bursting caused by squeezing the lens and the jig under high temperature during processing.
[0007] The industrial lens processing device of the embodiment of the utility model is simple in design and practical, and is more suitable for processing a large number of new materials emerging in the lens manufacturing industry, and plays a vital role in improving product quality and ensuring processing accuracy.
