[0002] With the rapid development of high-tech fields such as optics, optoelectronics, and aerospace, the performance requirements for optical glass are becoming increasingly stringent. Optical glass not only needs high light transmittance, low dispersion, and stable chemical properties, but also requires precise processing to meet specific application needs. The annealing furnace, as a key piece of heat treatment equipment, plays a crucial role in the production process of optical glass; therefore, it is necessary to design a precision annealing furnace for coated optical glass under vacuum atmosphere protection.

[0003] To address this, patent CN211005094U discloses a precision annealing furnace for optical glass. It includes: a furnace body, a heating layer, a circulating fan disposed on the rear wall of the furnace body, and an insulation layer surrounding the furnace body; the insulation layer, from the inside out, consists of a mullite brick layer, a ceramic fiberboard layer, and an asbestos board layer, and the insulation layer has a thickness of 300mm. The advantages of this invention are: the insulation layer, from the inside out, consists of a mullite brick layer, a ceramic fiberboard layer, and an asbestos board layer; the insulation layer thickness is increased to 300mm; the furnace door incorporates metal fiber strips, increasing the sealing contact area, enhancing its sealing performance, reducing the impact of heat loss, ensuring the accuracy of the annealing curve, and providing good thermal insulation.

[0004] Although the aforementioned precision annealing furnace for optical glass can ensure the accuracy of the annealing curve during use, the glass will produce a certain odor and release chemical substances after heating during the annealing process. It is inconvenient to remove the odor and chemical substances in the gas inside the annealing furnace. Therefore, it is necessary to design a precision annealing furnace for coated optical glass with vacuum atmosphere protection. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum atmosphere protected coating optical glass precision annealing furnace to solve the problem that existing optical glass precision annealing furnaces are inconvenient for removing odors and chemicals from the gas inside the furnace.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vacuum atmosphere protected coating optical glass precision annealing furnace, including a base;

[0007] An annealing assembly is fixed to the top of the base, and conveying structures are passed through both sides of the bottom of the annealing assembly. Lifting door panels are fixed to the top of the base on both sides of the annealing assembly.

[0008] The top of the annealing assembly is fixed with a deodorizing structure, which includes a limiting frame fixed to the top of the annealing assembly, a suction fan fixed to the top of the limiting frame, a protective cover fixed to the top of the limiting frame outside the suction fan, a processing box fixed to the top of the protective cover, an activated carbon layer inside the processing box, and a protective frame fixed to the top of the annealing assembly outside the protective cover.

[0009] Furthermore, the conveying structure includes an electric guide rail, a slider, and a support plate. The electric guide rails extend through both sides of the bottom of the annealing assembly. A slider is slidably connected to the outer side of each electric guide rail, and a support plate is fixed to the top of each slider.

[0010] Furthermore, one end of each of the electrical rails extends to the outside of the annealing assembly and is fixedly connected to the top of the base.

[0011] Furthermore, the annealing assembly includes an annealing furnace body, a suction pipe, an air inlet pipe, and a reserved slot. The annealing furnace body is fixed to the top of the base. A suction pipe is fixed to the top of the annealing furnace body. Air inlet pipes are fixed to both sides of the top of the annealing furnace body. Reserved slots are provided on both sides of the bottom of the annealing furnace body.

[0012] Furthermore, the top of the suction pipe extends into the interior of the limiting frame.

[0013] Furthermore, a temperature sensor is fixed on the inner wall of the top of the annealing furnace body, and a heating structure is fixed on the inner wall of the annealing furnace body on the side away from the reserved slot.

[0014] Furthermore, a microcontroller is installed inside the temperature sensor.

[0015] Furthermore, the heating structure includes a mounting frame, a heating wire, and a protective frame. The mounting frame is fixed to the inner walls on both sides of the annealing furnace body. The heating wire is fixed to the inner side of the mounting frame, and the protective frame is fixed to the outer wall of the heating wire.

[0016] Furthermore, the heating wires are symmetrically distributed on both sides of the annealing furnace body, and the input end of the heating wires and the output end of the temperature sensor are electrically connected via a single-chip microcomputer.

[0017] The advantages of the vacuum atmosphere protected coating optical glass precision annealing furnace body provided by this utility model are as follows:

[0018] By incorporating a deodorization structure, the gas inside the annealing furnace body can be drawn into the limiting frame through the suction pipe by the suction fan. Subsequently, the gas is drawn into the inner side of the protective cover by the suction fan. After entering the protective cover, the activated carbon layer can adsorb and treat the gas, removing odors and chemicals from it. The treated gas then returns to the inner wall of the annealing furnace body through the air inlet pipe, preventing heat loss. This device effectively removes odors and chemicals from the inside of the annealing furnace body, improving the convenience of using the vacuum atmosphere protected coated optical glass precision annealing furnace body.

[0019] With the addition of a conveying structure, the sliding connection between the electric guide rail and the slider facilitates the sliding of the slider and the support plate into the inner side of the annealing furnace body, making it easier to push the optical glass to be annealed into the interior of the annealing furnace body. This enables the device to facilitate the transfer of optical glass and improves the convenience and usability of the vacuum atmosphere protected coated optical glass precision annealing furnace body during use.

[0020] By incorporating a heating structure, the internal temperature of the annealing furnace body can be maintained under the heating action of the heating wire, ensuring the annealing effect of the optical glass. With the monitoring function of the temperature sensor, the internal temperature of the annealing furnace body can be easily monitored in real time, ensuring that the internal temperature of the annealing furnace body is suitable. This device realizes the function of easy monitoring and control of the internal temperature of the annealing furnace body, improving the working efficiency of the vacuum atmosphere protected coated optical glass precision annealing furnace body during use.

[0030] When an external power source is connected and the electric guide rail 21 is started, the slider 22 can slide on the outside of the electric guide rail 21 under electromagnetic action.
