Technical background: with the development of science and technology, the progress of The Times, the advanced optical technology not only applied in the field of military equipment, also began to spread in the people's livelihood development. Especially in recent years, with the development of mobile phone photography, optical electronics but also to the development of lightweight and thin, the corresponding camera module is also becoming more and more small, precision demand more and more is also high. Lens surface modification technology is more and more important, the key to decide the product quality. Technical implementation elements: the utility model provides an optical lens coating machine, using computer control to realize automatic operation, effectively reduce the manpower cost. The utility model provides an optical lens coating machine, including the vacuum chamber, respectively connected to the vacuum cavity of vacuum system and steam trap; Described in the vacuum chamber with internal coating umbrella, used for detecting the thickness of film coating monitor, heating agency, various institutions and coating film thickness correction, described in the coating umbrella set on the top of the vacuum chamber, heating is set up by coating the top of the umbrella, deposition mechanism set in the bottom of the vacuum chamber, film thickness correction mechanism set between the coating and coating umbrella organization, described coating umbrella in motor driven rotary motion. In the utility model of the optical lens coating machine, coating umbrella including spherical shape umbrella stand and multiple Settings described in umbrella stand on the surface of the lens inside the tank. In the utility model of the optical lens coating machine, described in the umbrella stand center equipped with hole, described coating monitor wear in the inside hole. In the utility model of the optical lens coating machine, coating institutions including ion source and electron gun. In the utility model of the optical lens coating machine, vacuum institutions including connection through vacuum line mechanical pump, roots pump and the oil diffusion pump, oil diffusion pump connected to the vacuum chamber, the vacuum line with rubber ring seal. In the utility model of the optical lens coating machine, described the oil diffusion pump equipped with water cooling system and cold trap. In the utility model of the optical lens coating machine, coating machine also has described the vacuum system, water vapor capture, coating monitoring mechanism, heating and coating mechanism to control the control cabinet. In the utility model of the optical lens coating machine, described in the control cabinet is equipped with touch screen. In the utility model of the optical lens coating machine, it is set in a vacuum chamber window. The utility model of an optical lens coating machine adopts computer control to realize automatic operation, can effectively reduce the manpower cost, ensure the consistency of product, reduce the error occurred. The coating machine can be used in optical glass lenses, optical plastic lens, semiconductor, metal, ceramic, etc for the substrate surface modification technology of media. Using the utility model of the coating machine steamed film, high optical transmittance, good appearance yield, effectively prevent the membrane layer crack. The coating machine in the actual production process, production, product quality is reliable, film adhesion is good, especially in the field of based on optical plastic products, has an absolute advantage. The appended drawings show figure 1 is the top view of the utility model of optical lens coating machine; Figure 2 is the utility model of the optical lens coating machine profile within the vacuum chamber; Figure 3 is the utility model of the optical lens coating machine coating umbrella schematic diagram. Under the specific implementation way combined with figure 1 to figure 3 of this utility model optical lens coating machine. As shown in figure 1, the utility model of optical lens coating machine including 10 vacuum chamber, vacuum institution and the institution of steam trap 20. Vacuum system and water vapor capture 20 respectively connected to the vacuum chamber 10. As shown in figure 2 vacuum chamber with internal coating of 10 1 umbrella, used for detecting the thickness of film coating monitor 2, heating body 3, 4 film thickness correction institutions and coating. Coating umbrella 1 set to 10 at the top of the vacuum chamber, heating is 3 set by coating the top of the umbrella 1, deposition mechanism set on the bottom of the vacuum chamber 10, film thickness correction institutions 4 set between coating umbrella 1 and deposition mechanism. Coating umbrella 1 7 in motor driven rotary motion. Coating 1 including spherical shape umbrella umbrella stand more than 11 and set in the umbrella stand 11 12 on the surface of the lens inside the groove. Has a hole in the center of the umbrella stand 11 of 13, coating monitor 2 wear in hole is 13. Coating institutions include ion source and gun 6 5. Set in the vacuum chamber 1 observation window. Vacuum institutions including connection through vacuum line mechanical pump, roots pump, 41 and 42 43, oil diffusion pump oil diffusion pump and connected to the vacuum chamber 1, vacuum line with rubber ring seal. 43 equipped with water-cooled oil diffusion pump system and the cold trap, can prevent oil molecules of vacuum chamber 10 pollution, guarantee the clean of the vacuum chamber. Coating machine also has the vacuum system, water vapor capture 20 3, 2, heating coating monitor institutions and deposition mechanism to control the control cabinet of 30. In the 30 on the control cabinet is equipped with touch screen. Coating machine of this utility model under the coating process description: placed for coating products in coating umbrella 1 lens slot within 12, 7 by motor control umbrella stand 11 to rotate 360 degrees. Start the vacuum mechanism of vacuum chamber 10 pumping air into vacuum state, in the process of pumping air into vacuum state through the steam trap body 20 to capture moisture within the vacuum chamber 10, at the same time start the heating mechanism 3 treat coating products for heating, when arrived at 10 vacuum degree within the vacuum chamber set value, the temperature at the same time also to reach the set value can begin to evaporate. At this point, the ion source and gun 5 6 began to work, coating monitor 2 start automatic control at the same time, until the steamed a complete set of film system, control cabinet and 30 control 10 automatic vacuum chamber is deflated and open the door. Can the process, through the observation window to see the real-time situation in the vacuum chamber 10. Membrane layer set and related process parameters can be finished in a touch screen. The utility model of an optical lens coating machine adopts computer control to realize automatic operation, can effectively reduce the manpower cost, ensure the consistency of product, reduce the error occurred. The coating machine can be used in optical glass lenses, optical plastic lens, semiconductor, metal, ceramic, etc for the substrate surface modification technology of media. Using the utility model of the coating machine steamed film, high optical transmittance, good appearance yield, effectively prevent the membrane layer crack. The coating machine in the actual production process, production, product quality is reliable, film adhesion is good, especially in the field of based on optical plastic products, has an absolute advantage. The coating machine without waste gas, waste oil, no any pollution to the environment, don't need to do environmental protection process, less pollution, low noise. Described above only for the better implementation of the utility model example, not to limit the thought of the utility model, all within the spirits and principles of the utility model, for any modification, equivalent replacement, improvement, etc. , shall be included within the scope of protection of the utility model.
