Description

Technical Field

[0001] This application relates to the technical field of glass lenses, specifically to a glass lens annealing device. Background Art

[0002] During the manufacturing process of glass lenses, due to various factors such as temperature gradients and uneven crystallization, internal stresses will inevitably be generated. If these stresses are not effectively released, they will have a negative impact on the optical properties of the lenses, such as causing optical distortion, speckle, etc. Annealing treatment controls the heating and cooling processes of the lenses, enabling the atoms and molecules inside the lenses to be rearranged, thereby releasing and eliminating internal stresses. This process helps to improve the optical properties of the lenses and enhance their stability and reliability.

[0038] At the same time, a placement table 6 is fixedly arranged on the conveyor belt 2, and the placement table 6 is used to place and position the glass lens during the annealing process, so that the glass lens can be stably annealed;

[0039] The placing platform 6 includes a fixed plate 60 fixedly arranged on the conveyor belt 2, and a plurality of support columns 61 are fixedly arranged on the fixed plate 60, and a connecting ring 64 is fixedly installed on the top of the supporting column 61, and the supporting column 61 is used to provide a stable support for the connecting ring 64;

[0040] Meanwhile, a second motor 62 is fixedly disposed at the bottom end of the fixing plate 60, and a rotating shaft 69 is fixedly connected to the output end of the second motor 62, and the rotating shaft 69 is bearing-mounted with the connecting ring 64, so that the second motor 62 can drive the rotating shaft 69 to rotate, and a rotating disk 63 is fixedly disposed at the upper end of the rotating shaft 69, and the rotating disk 63 is used to carry the glass lens during the annealing process, and can be driven by the second motor 62 to rotate, so as to evenly heat or cool the glass lens;

[0041] A clamping assembly is fixedly arranged at the upper end of the rotating disk 63, and the clamping assembly includes two sets of fixed blocks 70 fixed at the upper end of the rotating disk 63, and a telescopic rod 71 is fixedly arranged inside the fixed block 70, and the telescopic rod 71 is divided into a first rod fixedly installed inside the fixed block 70, and a second rod slidably arranged inside the first rod, so that the second rod can slide inside the first rod;

[0042] The first rod is arranged inside the fixed block 70. At the same time, a clamping plate 66 is fixedly arranged at one end of the second rod. The clamping plate 66 is arc-shaped to facilitate precise clamping and positioning of the glass lens and prevent it from moving or deforming during the annealing process.

[0043] At the same time, a receiving groove 67 is fixedly arranged on the turntable 63. The receiving groove 67 is used for placing and positioning the glass lens. At the same time, through holes are opened on both sides of the receiving groove 67. The through holes correspond to the clamping plate 66 to facilitate the clamping plate 66 to enter the inside of the receiving groove 67 to clamp the glass lens. And springs 65 are fixedly sleeved on the first rod and the second rod. The springs 65 are used for adaptive adjustment of glass lenses of different sizes.

[0044] According to the size of the glass lens and the required clamping force, the springs 65 will automatically adjust their compression amounts. Larger glass lenses will cause the springs 65 to compress more, while smaller glass lenses will compress less. Adaptive adjustment is carried out according to the different product sizes of the glass lenses and the required clamping force of each product model.

[0045] Such as Figure 1 and Figure 3 - Figure 5 As shown, a heating mechanism 4 is fixedly arranged at the upper end of the frame body 1. The heating mechanism 4 is used to heat the glass lens to a certain temperature to eliminate the internal stress and defects. At the same time, the heating mechanism 4 is arranged directly above the conveyor belt 2 to facilitate heating of the glass lens during transportation.

[0046] The heating mechanism 4 includes a first housing 40 fixed to the upper end of the frame body 1. The first housing 40 protects the internal components to ensure the safety and stability of the heating process. And a heating component 43 is fixedly arranged inside the first housing 40.

[0047] The heating component 43 includes a guard plate 430 fixed inside the first housing 40.

The second housing 50 is used to protect the internal components of the cooling mechanism 5 and provide a closed environment to promote air flow. Cooling fans 52 are fixedly arranged on both sides of the second housing 50, and the cooling fans 52 communicate with the inside of the second housing 50, so as to accelerate air circulation by generating a strong air flow, thereby taking away the heat on the glass lens and achieving rapid cooling;

[0051] An air outlet (not marked in the figure) is fixedly arranged at the upper end of the second housing 50. The air outlet is used to guide the hot air to discharge from the inside of the cooling mechanism 5, providing sufficient air flow for the cooling fans 52. At the same time, an air suction fan 51 is fixedly arranged at the upper end of the air outlet. The air suction fan 51 can be a commonly used air suction fan 51 in the prior art and suitable for this application, so as to stably discharge the hot air, thereby performing the cooling process;

[0052] In summary, before the annealing operation starts, the staff will put the glass lens into the receiving groove 67, and then use the clamping assembly to adaptively clamp the glass lens. After the glass lens is fixed by the clamping assembly, the second motor 62 drives the turntable 63 to rotate, so as to uniformly heat or cool the glass lens;

[0053] When the annealing operation starts, the conveyor belt 2 will transport the placement table 6 to the heating mechanism 4 to be heated to a certain temperature to eliminate the internal stress and defects. The glass lens on the placement table 6 in the heating mechanism 4 will be uniformly heated during the rotation of the turntable 63, so that the glass lens reaches a suitable state. After the heating process is completed, the conveyor belt 2 will transport the glass lens to the cooling mechanism 5 to quickly reduce the temperature of the glass lens to fix its shape and performance. When the cooling is completed, the annealing of the glass lens will be completed.

[0054] The above is only the preferred embodiment of the present application and is not used to limit the present application.
