[0002] Optical lenses are optical components used to control and manipulate the transmission of light. They are widely used in various fields, including optical instruments, lasers, optical communications, medical devices, etc. In telescopes and microscopes, lenses and objective lenses usually use optical lenses to change the transmission direction and magnification of light, so as to achieve the observation of distant objects or tiny objects. Among them, blue glass for infrared cut-off filters can effectively improve the ghost, stray light and color cast problems during imaging, thereby improving the image quality. Therefore, blue glass for infrared cut-off filters is a good raw material for manufacturing optical lenses.

[0003] In the production of optical lenses, in order to ensure that light can pass through the lenses smoothly and reduce light scattering and reflection, workers need to polish the surface of the lenses to remove the rough parts of the glass surface and make its surface smoother.

[0004] However, when most existing grinders are grinding lenses, the staff is required to manually clamp the lenses and manually adjust the placement of the lenses to ensure that the grinding disc is directly above the lenses. For example, Chinese patent CN219617377U discloses an optical lens grinding device. When manually adjusting the position of the lens, the staff is required to frequently adjust the clamps, which is too troublesome and increases the workload of the staff. Therefore, the present utility model is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the clamping and positioning mechanism includes a cavity 5 opened inside the workbench 4, and a vent hole extending to the outside of the workbench 4 is opened on one side of the cavity 5. The upper surface of the workbench 4 is provided with a plurality of clamping members extending into the cavity 5 to clamp the mirror, and adjustment components are provided on both sides of the clamping members.

[0024] See also Figure 1 and Figure 3 The clamping member includes a positioning rod 6 fixedly mounted on the upper surface of the workbench 4, the interior of the positioning rod 6 is an open structure, a positioning plate 7 is fixedly mounted on the upper surface of the positioning rod 6, an opening is opened on the upper surface of the positioning plate 7 and a suction cup 8 is fixedly mounted on the upper surface, an air pump 9 is fixedly mounted on the inner bottom wall of the cavity 5, and an air pipe extending to the interior of the positioning rod 6 and connected to the interior of the suction cup 8 is fixedly mounted on the output end of the air pump 9.

[0025] The internal gas is extracted through the suction cup 8, so that the suction cup 8 can firmly adsorb the lens.

[0026] It should be noted that the suction cup 8 is made of high-temperature rubber material and has good heat resistance.

[0027] See also Figure 1 and Figure 2 In this embodiment, the adjustment component includes a support plate 10 fixedly mounted on the upper surface of the workbench 4, a first electric push rod 11 is fixedly mounted on the side surface of the support plate 10 facing the positioning rod 6, an L-shaped moving plate 12 is fixedly mounted on the movable end of the first electric push rod 11, a second electric push rod 13 is fixedly mounted on the top of the moving plate 12, and the movable end of the second electric push rod 13 extends to the bottom of the moving plate 12 and is fixedly mounted with a U-shaped block 14.

[0028] The movable plate 12 is moved by the first electric push rod 11 so that the movable plate 12 can approach the positioning rod 6 or move away from the positioning rod 6, so as to adjust the position of the lens. The U-shaped block 14 is moved vertically by the second electric push rod 13 so that the U-shaped block 14 can approach the suction cup 8 or move away from the suction cup 8.

[0029] Among them, a splint 25 is arranged inside the U-shaped block 14, a rubber pad is fixedly installed on the lower surface of the splint 25, and a third electric push rod 15 is fixedly installed on the upper surface of the U-shaped block 14. The movable end of the third electric push rod 15 extends to the bottom of the U-shaped block 14 and is fixedly connected to the upper surface of the splint 25.

[0030] Secondly, a slide groove is provided on the upper surface of the workbench 4, and a slider 16 is fixedly installed on the lower surface of the movable plate 12, and the other end of the slider 16 extends into the inside of the slide groove and is slidably connected to the inner wall of the slide groove. Through the cooperation between the slide groove and the slider 16, the slider 16 can stably drive the movable plate 12 to move horizontally.

[0031] Example 2: Please refer to Figure 1 In this embodiment, the cleaning component includes a fixed plate 17 fixedly installed on the left surface of the workbench 4, a fan 18 is fixedly installed on the upper surface of the fixed plate 17 through a support column, a collecting tank 19 whose bottom is fixedly connected to the bottom wall of the box body 2 is fixedly installed on the right surface of the workbench 4, and a conveying pipe 20 is connected to one side surface of the collecting tank 19.

[0032] Since most of the waste generated when grinding lenses is dust, workers are very likely to inhale the dust into their bodies when cleaning it, which affects their health. Water is injected into the collection pool 19 through the conveying pipe 20 so that the water can absorb the dust and avoid dust splashing, so that the workers only need to filter the water afterwards.

[0033] See also Figure 1 In this embodiment, the grinding part includes a hydraulic cylinder 21 fixedly mounted on the upper surface of the box body 2, the movable end of the hydraulic cylinder 21 extends to the interior of the box body 2 and is fixedly mounted with a protective box, a motor 22 is fixedly mounted on the inner wall of the protective box, the output end of the motor 22 extends to the outside of the protective box and is fixedly mounted with a grinding disc 23, and a controller 24 is fixedly mounted on one side surface of the box body 2.

[0034] It should be noted that the grinding disc 23 is a prior art, and its specific structure and working principle are not described in detail herein.

[0035] It should be noted that, since the positions of the four positioning rods 6 are fixed, the staff only needs to measure the base points between the four positioning rods 6 and output the base point positions to the controller 24. When polishing the lens, the thickness and length of the lens are input into the controller 24. The controller 24 can start the operation of the above-mentioned electrical components according to the thickness and length of the lens. This method is a prior art, and its specific structure and working principle will not be repeated in this article.

[0036] The working principle of the above embodiment is as follows: the staff inputs the thickness and length of the lens into the controller 24, stably places the lens in the U-shaped block 14, drives the clamping plate 25 to move through the third electric push rod 15, thereby clamping the lens, and then closes the box door 3, and starts the device for overall operation through the controller 24. At this time, the first electric push rod 11 drives the moving plate 12 to move, so that the moving plate 12 can approach the positioning rod 6. When the lens moves to the base point, the first electric push rod 11 adjusts the operation. At this time, the second electric push rod 13 drives the U-shaped block 14 to move vertically, so that the U-shaped block 14 can drive the lens to contact the upper surface of the suction cup 8. At this time , the air pump 9 is started, and the internal gas is extracted through the suction cup 8, so that the suction cup 8 can firmly adsorb the lens, the third electric push rod 15 is started, so that the clamping plate 25 is away from the lens, and the first electric push rod 11 drives the moving plate 12 to reset, thereby completing the position adjustment of the lens. At this time, the hydraulic cylinder 21 is started, thereby driving the grinding disc 23 to move downward, and the motor 22 drives the grinding disc 23 to rotate, thereby grinding the lens. Through the above operations, the staff only needs to place the lens stably in the U-shaped block 14 and start the controller 24. Then the device can automatically adjust the position of the lens and grind the surface of the lens, reducing the workload of the staff.

[0037] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the text.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
