Description

Technical Field

[0001] This utility model relates to the technical field of lens drying devices, specifically a drying device for lens coating. Background Technology

[0002] During the lens processing, a lens coating drying device is needed. When the drying device is in use, a carrier plate with the lens is placed inside the drying oven, and the lens on the carrier plate is dried by the heating device inside the drying oven.

[0003] For example, an existing Chinese patent (publication number: CN217236335U) discloses a drying device for lens coating, which can blow air onto the upper and lower surfaces of the lens simultaneously through the first air outlet and the second air outlet, thereby improving the drying efficiency of this structure.

[0004] However, the drying device for lens coating designed above still has some drawbacks in actual use: although the drying device can use the first air outlet, the second air outlet, the first fan and the second fan to blow air on the upper and lower surfaces of the lens at the same time, the setting of two fans will undoubtedly increase the cost of use, maintenance and repair.

[0005] To address these issues, we designed a drying device for lens coating. Utility Model Content

[0006] The purpose of this invention is to provide a drying device for lens coating, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a drying device for lens coating, including a drying box. Two air collection boxes are symmetrically arranged in the horizontal direction inside the drying box. Each of the two air collection boxes has an air jet port connected to the interior on one side opposite to the other. A filter screen for placing the lens is fixedly installed inside the drying box. The filter screen is located between the two air collection boxes. A drying component for drying the lens is provided inside the drying box. The drying component is connected to the air collection boxes.

[0008] Furthermore, the drying assembly includes an air pump, which is fixedly embedded in one side of the drying chamber, with its air outlet and air inlet located inside and outside the drying chamber, respectively. The air outlet of the air pump is provided with a three-way pipe, and the other two ends of the three-way pipe are fitted with L-shaped pipes. The other end of the L-shaped pipe is fixedly inserted into one side of the air collection box. Heating blocks are fixedly installed on the inner rings of the two ends of the three-way pipe away from the air pump, and electric heating wires are provided inside the heating blocks.

[0009] Furthermore, a fixing frame is fixedly installed on the inner side wall of the drying oven in the vertical direction. A threaded screw is rotatably installed inside the fixing frame. Two nuts are symmetrically threaded on the threaded screw. One end of the nut slides through the fixing frame and is fixedly connected to one side of the air collection box. A motor is installed on the top of the fixing frame. The drive shaft of the motor is connected to one end of the threaded screw. The L-shaped tube is movably sleeved on the tee pipe.

[0010] Furthermore, the mounting frame has an installation cavity and two fixing ports on its interior and one side, respectively. The installation cavity is connected to the fixing ports. The threaded rod is rotatably disposed in the installation cavity in the vertical direction, and one end of the nut is slidably inserted into the fixing port.

[0011] Furthermore, a guide rod is fixedly installed vertically inside the mounting cavity, and a limiting hole adapted to the guide rod is provided inside the nut. The nut is slidably sleeved on the guide rod through the limiting hole.

[0012] Furthermore, a fence is fixedly installed around the top of the filter screen.

[0013] Furthermore, a mounting hole is provided on one side of the drying oven, the mounting hole is connected to the interior of the drying oven, and the air pump is fixedly installed in the mounting hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting up a drying component, hot air can be delivered to two air collection boxes respectively, and finally blown onto the bottom and top of the lens through multiple air jets on the air collection box, so as to achieve the effect of drying both sides of the lens at the same time. In addition, the whole process can be completed with only a single air pump, which reduces the cost of use, maintenance and repair.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by turning on the motor, the drive shaft of the motor can drive the threaded screw to rotate, so that the two nuts drive the two air collection boxes to move away from each other and closer together along the direction set by the guide rod, thereby adjusting the distance between the two air collection boxes. This is applicable to lenses of different thicknesses and improves the performance. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a drying device for lens coating, including a drying box 1, two air collection boxes 2 are symmetrically arranged in the horizontal direction inside the drying box 1, and each of the two air collection boxes 2 has an air jet 3 connected to the interior on one side opposite to the interior. A filter screen 8 for placing lenses is fixedly installed inside the drying box 1, and the filter screen 8 is located between the two air collection boxes 2. A drying component for drying the lenses is provided inside the drying box 1, and the drying component is connected to the air collection boxes 2.

[0023] The drying assembly includes an air pump 4, which is fixedly embedded on one side of the drying chamber 1. The air outlet and air inlet of the air pump 4 are located inside and outside the drying chamber 1, respectively. The air outlet of the air pump 4 is provided with a three-way pipe 5. The other two ends of the three-way pipe 5 are fitted with L-shaped pipes 6. The other end of the L-shaped pipe 6 is fixedly inserted into one side of the air collection box 2. The inner rings of the two ends of the three-way pipe 5 away from the air pump 4 are fixedly installed with heating blocks 7. The heating blocks 7 are provided with electric heating wires.

[0024] In practice, the coated lens to be dried is placed on the filter screen 8, and then the air pump 4 and the three-way pipe 5 are turned on. The air pump 4 draws outside air into the three-way pipe 5 and mixes it with heat. The mixed hot air is then delivered to the two air collection boxes 2 through the L-shaped pipe 6. Finally, the air is blown onto the bottom and top of the lens through multiple air jets 3 on the air collection box 2, achieving the effect of drying both sides of the lens at the same time. In addition, the whole process can be completed with only a single air pump 4, which reduces the cost of use, maintenance and repair.

[0025] See Figure 1-4A fixed frame 9 is fixedly installed on the inner side wall of the drying oven 1 along the vertical direction. A threaded screw 10 is rotatably installed inside the fixed frame 9. Two nuts 11 are symmetrically threaded on the threaded screw 10. One end of the nut 11 slides through the fixed frame 9 and is fixedly connected to one side of the air collection box 2. A motor 12 is installed on the top of the fixed frame 9. The drive shaft of the motor 12 is connected to one end of the threaded screw 10. An L-shaped tube 6 is movably sleeved on the three-way tube 5.

[0026] In practice, based on the above implementation, the motor 12 is turned on, causing the drive shaft of the motor 12 to drive the threaded screw 10 to rotate, so that the two nuts 11 drive the two air collection boxes 2 to move away from each other and closer together, thereby adjusting the distance between the two air collection boxes 2. This can be applied to lenses of different thicknesses and improve the performance.

[0027] See Figure 1-4 The mounting bracket 9 has an installation cavity 13 and two fixing ports 14 on its interior and one side, respectively. The installation cavity 13 is connected to the fixing ports 14. The threaded screw 10 is rotatably mounted in the installation cavity 13 in the vertical direction, and one end of the nut 11 is slidably inserted into the fixing port 14. This allows the threaded screw 10 to be easily rotatably mounted in the mounting bracket 9, and also facilitates the normal movement of the nut 11, avoiding the problem of motion interference.

[0028] See Figure 1-4 A guide rod 15 is also fixedly installed vertically inside the mounting cavity 13. A limiting hole adapted to the guide rod 15 is provided in the nut 11, and the nut 11 is slidably sleeved on the guide rod 15 through the limiting hole. This allows the nut 11 to slide only along the direction set by the guide rod 15, avoiding the problem of movement deviation.

[0029] See Figure 1-4 The top of the filter 8 is fixedly equipped with railings 16. This can easily limit the movement of the lens and prevent it from sliding off the filter 8. It should be noted that since the lens is exposed to hot air from both above and below, instability is almost non-existent.

[0030] See Figure 1-4 A mounting hole 17 is provided on one side of the drying oven 1, which is connected to the interior of the drying oven 1. The air pump 4 is fixedly installed in the mounting hole 17. This not only facilitates the installation of the air pump 4, but also allows the air pump 4 to easily draw in air from the outside.

[0031] It should be noted that although the front of the drying oven 1 is hinged to a door panel as shown in the figure, there is a gap between the door panel and the drying oven 1 to avoid the problem of uneven air pressure inside and outside the drying oven 1.

[0032] Before use, all electrical appliances inside and outside the drying oven 1 need to be connected to an external power source, or a battery pack should be installed in an area outside the drying oven 1 that does not obstruct other components. Then, the battery pack and electrical appliances should be connected via wiring. It is also necessary to avoid the wiring from becoming tangled due to the movement of the components. Wiring should be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0033] Working principle: When in use, first place the coated lens to be dried on the filter screen 8, then turn on the air pump 4 and the three-way pipe 5. The air pump 4 can draw outside air into the three-way pipe 5 and mix it with heat. Then the mixed hot air will be delivered to the two air collection boxes 2 through the L-shaped pipe 6. Finally, the air is blown onto the bottom and top of the lens through multiple air jets 3 on the air collection box 2, achieving the effect of drying both sides of the lens at the same time. In addition, the whole process can be completed by only a single air pump 4, which reduces the cost of use, maintenance and repair.

[0034] In addition, before the above operation, the motor 12 can be turned on, so that the drive shaft of the motor 12 drives the threaded screw 10 to rotate, so that the two nuts 11 drive the two air collection boxes 2 to move away from each other and closer together along the direction set by the guide rod 15, thereby adjusting the distance between the two air collection boxes 2. This can be applied to lenses of different thicknesses and improve the performance.
