Description

Technical Field

[0001] The utility model belongs to the technical field of colored lens processing, in particular to an annealing device for removing residual stress of colored lens blanks. Background Art

[0002] The main function of the tinted lens annealing furnace is to eliminate or reduce the various thermal stresses formed in the tinted lens during the forming process, thereby improving the optical properties of the tinted lens, stabilizing the internal structure of the lens, and avoiding explosion, thereby improving the quality and strength of the lens.

[0003] A search revealed a patent document with the patent publication number CN217997028U, which discloses a glass lens annealing device. This device belongs to the field of glass lens processing technology and includes a furnace body with a furnace chamber, a lens fixture for placing the glass lens, and a lifting device for driving the lens fixture in and out of the furnace chamber. The furnace body is sequentially provided with a quartz layer, an inner insulation layer, a protective layer, an inductive coil layer, and a protective cover. The inductive coil layer contains an inductive coil for heating the lens fixture. By providing an inductive heating coil, the utility model can uniformly heat the lens fixture, ensuring that the temperature rises and falls of the glass lens at various locations on the lens chuck are synchronized, thereby improving the quality and efficiency of glass lens annealing. Furthermore, the furnace chamber is provided with a bottom opening, a lifting device, and a single-axis slide, which can drive the lens fixture in and out of the furnace chamber, resulting in a highly efficient annealing process.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the above-mentioned glass lens annealing device, the lifting device adopts a scissor-type lift (preferably a plurality of servo electric cylinders can be used as supporting legs for lifting), and the height is controlled by controlling the movement of the hydraulic lever through a hydraulic pump to drive the lens fixture into or out of the furnace. The scissor-type lift adopts an existing single-layer scissor arm platform, for example: a single-layer scissor arm platform produced by Marco Hydraulic Lifting Platform (Ningbo) Co., Ltd., model: M-DB. A ceramic carrier plate is provided on the lifting device, and the ceramic carrier plate is made of SiC ceramic material, which can play a heat insulating role; the single-axis slide adopts an existing single-axis slide, including a slide, and the bottom of the lifting device is connected to the slide. The lifting device can move back and forth under the drive of the single-axis slide motor. However, the operation steps are relatively complicated, thereby increasing the operation workload of the staff, and the moving stroke of the glass lens is large, which increases the annealing time of the glass lens, thereby reducing the annealing efficiency of the glass lens;

[0006] 2. The above-mentioned glass lens annealing device has a furnace chamber provided in the furnace body, the opening of the furnace chamber is located at the bottom of the furnace body, and a base is provided on the furnace body, which is fixed to the bracket through the base. However, it is not convenient to block the entrance end of the furnace chamber, and it is not convenient to separate the entrance end of the furnace chamber from the lens fixture, which may cause the heat inside the furnace chamber to accidentally injure the staff, thereby reducing the safety of the staff when taking and placing the glass lenses.

[0007] To this end, we provide an annealing device for removing residual stress of colored lens blanks to solve the above problems. Utility Model Content

[0013] The utility model is further configured such that the carrier is U-shaped, the metal induction plate and the chuck arranged inside the carrier are stacked on each other, and grooves are opened at equal intervals on the inner surface of the chuck.

[0014] The present invention is further configured such that a limiting nut is threadedly connected to the peripheral side wall of the transverse shaft, and the limiting nut is abutted against the outer side wall of the furnace body.

[0015] The present invention is further configured such that guide shafts are connected to the side walls of the isolation plate in a rectangular array, and the ends of the guide shafts pass through the inner side walls of the furnace body.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model sets a distance adjustment component, starts the motor, rotates the lead screw, and moves the two ball nuts at the same time, thereby causing the carrier and the furnace body to move on the substrate at the same time, thereby shortening the moving stroke of the carrier and the furnace body, and thus facilitating the speed of moving the carrier out of the furnace body, thereby effectively improving the annealing efficiency of the colored lens blank.

[0020] 2. The utility model provides an isolation component. When the carrier is moved out of the interior of the furnace body, the contracted spring body extends, and the isolation plate moves along the horizontal axis and the guide shaft toward the entrance of the furnace body, thereby separating the entrance of the furnace body and the carrier, thereby effectively preventing the heat inside the furnace body from accidentally injuring the staff, thereby improving the safety of the staff when removing the colored lens blanks on the chuck.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
