Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to pre-cooling equipment for lens production. Background Art

[0002] Optical instrument lenses are key components used in optical instruments. They refract, reflect or transmit light to achieve optical imaging, spectrometry, ranging and other functions. After the plane mirrors are polished in batches, the heat generated during the processing will cause slight deformation or stress on the lens surface. At this time, pre-cooling the lens helps stabilize its shape, so a pre-cooling device is required.

[0003] The pre-cooling equipment in the prior art generally consists of a box, a cold medium, and a placement plate. Usually, the polished lens is placed on the placement plate inside the box, and the cold medium is used to perform heat exchange on the lens, thereby reducing the temperature of the lens.

[0004] However, the above-mentioned pre-cooling equipment still has some problems. In actual applications, when pre-cooling the lens, the cold medium is usually fixed inside the box, so that the cold medium cannot effectively cover the entire surface of the lens, resulting in uneven cooling of different parts of the lens, which will affect the optical performance and quality of the lens. Therefore, a lens production pre-cooling equipment is proposed to address the above problems. Utility Model Content

[0008] Preferably, two slide grooves are symmetrically opened inside the pre-cooling box, a slider is slidably installed inside the slide groove, a support plate is installed on the top side of the slider, a push handle is fixed to one side of the support plate, and a placement component is installed on the top side of the support plate.

The convex rod 14 is matched with the U-shaped groove 5, and a control panel 31 is installed on one side of the pre-cooling box 1; when working, in actual application, when pre-cooling the lens, the cold medium is usually fixed inside the box body, so that the cold medium cannot effectively cover the entire surface of the lens, resulting in uneven cooling of different parts of the lens, which will affect the optical performance and quality of the lens. After the drive motor 11 is started, its output end drives the fan-shaped disk 12 to rotate, and the connecting rod 13 and the convex rod 14 rotate accordingly. The convex rod 14 cooperates with the U-shaped groove 5 during rotation. When the convex rod 14 enters the U-shaped groove 5, it will push the turntable 3 to rotate, and the connecting pipe 2 will also rotate accordingly, thereby driving the rotation of the delivery pipe 7 and the nozzle 8. Through the above-mentioned indirect rotating component, it can be ensured that the lens is evenly and comprehensively cooled during the pre-cooling process, avoiding lens deformation or stress caused by uneven temperature distribution.

[0024] See also Figure 3-4As shown, a circular groove 15 is provided inside the top end of the connecting tube 2, and an air supply pipe 16 is slidably installed inside the circular groove 15. One end of the air supply pipe 16 is connected with a mounting cavity 17, and a support rod 18 is fixed to the inside of the mounting cavity 17. A negative pressure motor 19 is installed on the top end of the support rod 18, and three fan blades 20 are equidistantly installed on the output end of the negative pressure motor 19. A filter screen 21 is threadedly installed on the other end of the mounting cavity 17. During operation, after the plane mirrors are polished in batches, the heat generated during the processing will cause slight deformation or stress on the surface of the lens. At this time, pre-cooling the lens helps to stabilize its shape. Therefore, a pre-cooling device is needed. In order to prevent the outside air from polluting the mirror surface, the negative pressure motor 19 is started, and its output end drives the three fan blades 20 to start rotating. The rotation of the fan blades 20 generates suction, so that the external air is sucked into the installation cavity 17 through the filter 21. The function of the filter 21 is to prevent dust, impurities and other particles from entering the air supply system. The air sucked into the installation cavity 17 is then transported through the air supply pipe 16. The air supply pipe 16 transports the clean air to the inside of the connecting pipe 2, and then enters the pre-cooling box 1 through the connecting pipe 2 to cool the lens, ensuring that the cooling air is clean and free of impurities, thereby avoiding contamination of the lens.

[0026] The placement assembly includes a fixing rod 26 fixed to the top side of the support plate 24. Four placement trays 27 are evenly mounted on the outer wall of the fixing rod 26. The placement trays 27 have a plurality of through holes 28 formed therein. The nozzles 8 are respectively disposed on both sides of each placement tray 27.

[0027] A movable door 29 is installed on one side of the pre-cooling box 1 through a hinge, and a handle 30 is fixed on one side of the movable door 29; during operation, on the lens production line, the lens needs to be pre-cooled after the grinding process is completed in order to better carry out subsequent processing or storage. At this time, the operator will come to the pre-cooling equipment and prepare to pre-cool the lens. The movable door 29 is opened by the handle 30. Then the operator holds the push handle 25 and slides the slider 23 along the direction of the slide groove 22. The sliding of the slider 23 in the slide groove 22 enables the support plate 24 to move back and forth in the pre-cooling box 1. When the support plate 24 moves to the appropriate position, the operator can place the lens to be pre-cooled on the placement tray 27. Since the nozzles 8 are respectively arranged on both sides of each placement tray 27 and with the cooperation of the through hole 28, no matter where the lens is placed, it can be evenly and efficiently cooled. After the lens is placed, the movable door 29 is closed, and then the pre-cooling equipment is started through the control panel 31 to facilitate the placement and removal of the lens.

[0028] Working principle: open the movable door 29 through the handle 30, then the operator holds the push handle 25 and slides the slider 23 along the direction of the slide groove 22. The sliding of the slider 23 in the slide groove 22 enables the support plate 24 to move back and forth in the pre-cooling box 1. When the support plate 24 moves to the appropriate position, the operator can place the lens to be pre-cooled on the placement tray 27. Since the nozzles 8 are respectively located on both sides of each placement tray 27 and with the cooperation of the through hole 28, no matter where the lens is placed, it can be cooled evenly and efficiently. After the lens is placed, close the movable door 29, and then start the pre-cooling device through the control panel 31 to facilitate the placement and removal of the lens.

[0029] The negative pressure motor 19 is started, and its output end drives the three fan blades 20 to start rotating. The rotation of the fan blades 20 generates suction, so that the external air is sucked into the installation cavity 17 through the filter 21. The function of the filter 21 is to prevent dust, impurities and other particles from entering the air supply system. The air sucked into the installation cavity 17 is then transported through the air supply pipe 16. The air supply pipe 16 transports the clean air to the inside of the connecting pipe 2, and then enters the pre-cooling box 1 through the connecting pipe 2 to cool the lens, ensuring that the cooling air is clean and free of impurities, thereby preventing the lens from being contaminated;

[0030] At the same time, the drive motor 11 is started, and its output end drives the sector disk 12 to rotate, and the connecting rod 13 and the convex rod 14 rotate accordingly. The convex rod 14 cooperates with the U-shaped groove 5 during rotation. When the convex rod 14 enters the U-shaped groove 5, it will push the turntable 3 to rotate, and the connecting tube 2 will also rotate accordingly, thereby driving the rotation of the conveying pipe 7 and the nozzle 8. Through the above-mentioned indirect rotating component, it can be ensured that the lens is evenly and comprehensively cooled during the pre-cooling process, avoiding uneven temperature distribution causing lens deformation or stress.
