Description

Technical Field

[0001] This utility model relates to the field of point diffusion lens preparation technology, specifically a drying device for preparing point diffusion lenses. Background Technology

[0002] Dot diffusion lenses, also known as DOT lenses, work by using special microstructures (such as tiny light diffusion points) on the lens to create a slight blurring or diffusion effect on the retina, thereby reducing retinal contrast. They are especially suitable for children who do not respond well to defocus lenses and orthokeratology lenses, as well as children with visual function or eye alignment abnormalities.

[0003] In the manufacturing process of dot diffusion lenses, a drying device is needed to remove surface moisture so that the dot diffusion lenses can be quickly processed in subsequent steps.

[0004] Currently, when drying equipment is used, the point diffusion lens is often placed directly inside the device. However, the contact surface between the point diffusion lens and the device's inner cavity is difficult to dry completely, which greatly affects the overall drying effect.

[0005] To address this problem, the present invention provides a drying apparatus for preparing point diffusion lenses. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1-4 A drying device for preparing point diffusion lenses includes a drying chamber 1. An electric heating wire 2 is fixedly connected to one side inside the drying chamber 1. Multiple air-generating tubes 3 are fixedly connected to the top of the drying chamber 1 near the electric heating wire 2. A fan 4 is fixedly connected inside each air-generating tube 3. Extension seats 5 are fixedly connected to both sides of the drying chamber 1 away from the air-generating tubes 3. A support shaft 6 is rotatably connected between two extension seats 5. A box cover 7 is fixedly connected to the middle of the support shaft 6. A drive motor 8 is fixedly connected to one side of one of the extension seats 5, and the output end of the drive motor 8 is also fixedly connected to the support shaft 6. A lens mounting mechanism 9 is provided at the bottom inside the drying chamber 1. A linkage component 10 is provided between the lens mounting mechanism 9 and the box cover 7. The linkage component 10 is used to adjust the mounting state of the lens mounting mechanism 9.

[0026] In this embodiment, a support ring is fixedly connected to the top of each air duct 3, and an air filter plate is fixedly connected inside the support ring. By using the air filter plate, the airflow entering the drying chamber 1 can be filtered to prevent impurities from entering the drying chamber 1. The material of the air filter plate can be activated carbon.

[0027] The lens mounting mechanism 9 includes a mounting base 11, a mounting shaft 12, a placement frame 13, and a positioning plate 14. The mounting base 11 is fixedly connected to the bottom of the drying oven 1. The mounting shaft 12 is rotatably connected to both ends of the mounting base 11. The placement frame 13 is fixedly connected between the two mounting shafts 12. The positioning plate 14 is fixedly connected to one side of the placement frame 13. The limiting plate 15 is slidably connected to the side of the placement frame 13 away from the positioning plate 14. The transmission screw 16 is threadedly connected to the side of the placement frame 13 near the limiting plate 15, and one end of the transmission screw 16 is rotatably connected to the limiting plate 15.

[0028] In this embodiment, multiple arc-shaped grooves are provided on the side of the positioning plate 14 and the limiting plate 15 that are close to each other, and anti-slip textures are provided on the arc-shaped grooves. The arc-shaped grooves can be adapted to the arc surface of the dot diffuser lens, thereby ensuring the positioning effect of the positioning plate 14 and the limiting plate 15 and preventing the dot diffuser lens from moving uncontrollably between the positioning plate 14 and the limiting plate 15.

[0029] In this embodiment, a stabilizing slide rod is slidably connected to the side of the placement frame 13 near the limiting plate 15, and one end of the stabilizing slide rod inside the placement frame 13 is also fixedly connected to the limiting plate 15. By using the stabilizing slide rod, the displacement of the limiting plate 15 can be guided to avoid uncontrollable displacement of the limiting plate 15, thereby ensuring the positioning effect of the limiting plate 15.

[0030] Example 2:

[0031] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: the linkage component 10 includes mounting ears 17, linkage shaft 18, linkage plate 19 and conduction plate 20. Mounting ears 17 are fixedly connected to both sides inside the drying box 1. The linkage shaft 18 is rotatably connected to one side of the mounting ears 17. The linkage plate 19 is fixedly connected to one end of the linkage shaft 18. The conduction plate 20 and guide plate 21 are rotatably connected to both ends of the linkage plate 19, and the end of the conduction plate 20 away from the linkage plate 19 is also rotatably connected to the box cover 7. Mounting pins 22 are fixedly connected to both ends of the placement frame 13, and the ends of the two guide plates 21 away from the linkage plate 19 are rotatably connected to the two mounting pins 22, respectively.

[0032] In this embodiment, the bottom end of the box cover 7 is fixedly connected to a mounting ear, and the end of the transmission plate 20 away from the linkage plate 19 is connected to the mounting ear through a rotating shaft. By using the mounting ear, the transmission plate 20 can be effectively assembled, ensuring the smooth connection of the transmission plate 20 between the box cover 7 and the linkage plate 19.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: First, place the dot diffuser lens in an orderly manner in the gap between the positioning plate 14 and the limiting plate 15. Then, rotate the transmission screw 16. With the connection between the transmission screw 16 and the placement frame 13, the transmission screw 16 can gradually move into the placement frame 13, thereby pushing the limiting plate 15 to move until the dot diffuser lens is positioned between the positioning plate 14 and the limiting plate 15.

[0035] The drive motor 8 is started to drive the support shaft 6 to rotate, thereby causing the box cover 7 to flip downward. Since the transmission plate 20 is connected between the box cover 7 and the linkage plate 19, when the box cover 7 flips, the transmission plate 20 can push the linkage plate 19, causing the linkage plate 19 to rotate under the support of the linkage shaft 18. Since the guide plate 21 is connected between the linkage plate 19 and the assembly pin 22, when the linkage plate 19 rotates, the guide plate 21 can pull the assembly pin 22, thereby causing the placement frame 13 to rotate under the support of the assembly shaft 12. When the box cover 7 is placed on top of the drying box 1, the placement frame 13 stands up simultaneously.

[0036] When the electric heating wire 2 and the fan 4 are started, the heat generated by the electric heating wire 2 will raise the temperature inside the drying chamber 1. The fan 4 will then inject airflow into the drying chamber 1 through the air duct 3 and blow it onto the upright point diffusion lens, thereby drying the multiple sides of the point diffusion lens.
