Technical Field

[0001] This invention relates to the field of glass lens polishing technology, specifically to a glass lens polishing device for optical instrument manufacturing. Background Technology

[0002] Glass lenses used in the manufacture of optical instruments are optical components made of transparent glass. Qualified glass blocks are heated and forged to form optical lens blanks. According to their shape, they can be divided into plane mirrors, spherical mirrors, and aspherical mirrors. According to their degree of reflection, they can be divided into total reflection mirrors and semi-transparent and semi-reflective mirrors. They play an important role in fields such as astronomy, military, transportation, medicine, and art. Qualified glass blocks are heated and forged to form optical lens blanks. Afterward, the glass lenses are polished according to the requirements of different optical instruments.

[0003] In the manufacturing process of optical instruments, the polishing of glass lenses is one of the key steps.

The flushing spray pipe is inclined and located outside the grinding disc.

[0011] Furthermore, there are multiple nozzles, which are distributed at equal intervals on the outside of the mounting tube and located on the upper surface of the inclined plate.

[0012] Furthermore, the drive structure includes a rotating shaft fixedly connected to the outside of the transmission gear and a worm fixedly connected to the top output shaft of the dual-axis motor.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 4 This embodiment of a glass lens polishing device for manufacturing optical instruments includes a base 1, a polishing mechanism 2 disposed on the top of the base 1, a cleaning tank assembly 3 fixedly connected to the top of the base 1, and a recycling tank 6 fixedly connected to the outside of the base 1. The cleaning tank assembly 3 includes a cleaning tank 31 fixedly connected to the top of the base 1 and an inclined plate 32 fixedly connected to the inside of the cleaning tank 31. The outside of the polishing mechanism 2 is provided with a cleaning mechanism 4 extending into the inside of the cleaning tank 31 for auxiliary cleaning and recycling of wastewater and debris mixture.

[0028] The grinding mechanism 2 includes a mounting frame 21 set on the top of the base 1. A dual-axis motor 22 is fixedly mounted on the top of the mounting frame 21. A grinding disc 23 is fixedly connected to the output shaft at the bottom of the dual-axis motor 22. A lifting structure is provided on the outside of the mounting frame 21.

[0029] Specifically, the lifting structure includes two electric push rods 24 fixedly mounted on the top of the base 1. A horizontal plate 25 is fixedly connected to the output end of each electric push rod 24, and a mounting bracket 21 is fixedly connected to the bottom of the horizontal plate 25. By extending and retracting the electric push rods 24, the horizontal plate 25 moves up and down, thereby adjusting the height of the mounting bracket 21 and the grinding disc 23. This allows the device to adapt to the grinding needs of glass lenses of different thicknesses without requiring equipment replacement or complex adjustments, improving the device's versatility and applicability.

[0030] Please see Figures 1 to 4 In this embodiment, the cleaning mechanism 4 includes a fixed base 41 fixedly connected to the bottom wall of the mounting frame 21 and an installation tube 49 fixedly connected to the inner wall of the cleaning tank 31. A pump housing 42 is fixedly connected to the top of the fixed base 41. A transmission gear 43 and a driven gear 44 are rotatably connected to the left and right sides inside the pump housing 42, respectively. A nozzle 410 that is inclined is fixedly connected to the outside of the installation tube 49. A drive structure is provided on the outside of the transmission gear 43.

[0031] The base 1 is externally fixedly connected to a water tank 412, and a pump casing 42 and a water tank 412 are fixedly connected by a suction pipe 411. A one-way valve is fixedly installed inside the suction pipe 411.

[0032] Specifically, a three-way pipe 48 is fixedly connected to the bottom of the pump casing 42. One end of the bottom of the three-way pipe 48 is fixedly connected to a conveying pipe 413 between it and the mounting pipe 49. The other end of the bottom of the three-way pipe 48 is fixedly connected to a flushing nozzle 414 extending to the lower surface of the mounting bracket 21. The flushing nozzle 414 is inclined and positioned outside the grinding disc 23. Water is divided into two paths through the three-way pipe 48. One path is conveyed through the conveying pipe 413 to the mounting pipe 49, and then sprayed out through multiple equally spaced and inclined nozzles 410 to flush the wastewater and debris mixture accumulated on the inclined plate 32, causing it to flow towards the bottom of the cleaning tank 31. The other path is sprayed directly onto the grinding disc 23 and the surface of the glass lens through the flushing nozzle 414 to cool and flush the grinding area, and promptly wash away the debris generated during grinding. This multi-directional flushing method has a significant cleaning effect and is carried out simultaneously with the grinding process, improving work efficiency.

[0033] It should be noted that the drive structure includes a rotating shaft 45 fixedly connected to the outside of the transmission gear 43 and a worm gear 47 fixedly connected to the top output shaft of the dual-shaft motor 22. A worm wheel 46 is fixedly mounted on the outside of the rotating shaft 45. The worm gear 47 and the worm wheel 46 mesh with each other, and the transmission gear 43 and the driven gear 44 mesh with each other. By using the top output shaft of the dual-shaft motor 22 as a power source, the meshing transmission of the worm gear 47 and the worm wheel 46 drives the rotating shaft 45 and the transmission gear 43 to rotate, thereby driving the driven gear 44 to rotate, forming a working principle similar to a gear pump, drawing water from the water tank 412 and pressurizing and transporting it, making full use of existing power and reducing energy consumption and equipment costs.

[0034] In addition, there are multiple nozzles 410, which are distributed at equal intervals on the outside of the mounting tube 49 and located on the upper surface of the inclined plate 32.

[0035] It is worth mentioning that a sludge pump is fixedly installed on the back of the base 1. The output and input ends of the sludge pump are connected to the recycling tank 6 and the cleaning tank 31 respectively through connecting pipes. The inclined plate 32 facilitates the flow of the wastewater and debris mixture to the bottom of the cleaning tank 31. Combined with the suction action of the sludge pump, the wastewater and debris mixture in the cleaning tank 31 can be quickly pumped into the recycling tank 6 for centralized collection and treatment. This avoids debris accumulation and blockage on the inclined plate 32, ensuring a smooth recycling process, improving recycling efficiency, and reducing the amount of manual cleaning work.

[0036] Please see Figure 1 and Figure 3In this embodiment, a limiting mechanism 5 extending into the cleaning chamber 31 is provided on the top of the base 1. The limiting mechanism 5 includes a vacuum pump 51 fixedly installed on the top of the base 1 and a negative pressure adsorption plate 53 disposed inside the cleaning chamber 31. A flexible hose 52 is fixedly connected between the input end of the vacuum pump 51 and the negative pressure adsorption plate 53. By using the vacuum pump 51 to extract the air from the negative pressure adsorption plate 53 through the flexible hose 52, a negative pressure environment is formed, thereby firmly adsorbing the glass lens onto the negative pressure adsorption plate 53. This is not only stable and reliable, but also effectively prevents the lens from shifting during the polishing process, ensuring the precision and quality of polishing. The negative pressure adsorption plate 53 is fixedly connected to the inner wall of the cleaning chamber 31 through a connecting plate 54, resulting in a stable structure. Furthermore, the outer diameter of the negative pressure adsorption plate 53 is adapted to the inner diameter of the cleaning chamber 31, ensuring the accuracy of lens placement.

[0037] The negative pressure adsorption plate 53 is fixedly connected to the left and right sides of the outside, and the connecting plates 54 are fixedly connected to the inner wall of the cleaning tank 31.

[0038] Specifically, the outer diameter of the negative pressure adsorption plate 53 is matched with the inner diameter of the cleaning box 31, and the negative pressure adsorption plate 53 is located above the inclined plate 32.

[0039] The working principle of the above embodiments is as follows:

[0040] In use, the glass lens to be polished is placed on the negative pressure adsorption plate 53 inside the cleaning tank 31. The vacuum pump 51 is started by the controller, and the vacuum pump 51 extracts the air from the negative pressure adsorption plate 53 through the hose 52, creating a negative pressure inside the negative pressure adsorption plate 53, thereby firmly adsorbing and fixing the glass lens on the negative pressure adsorption plate 53, ensuring the stability of the lens during polishing. The dual-axis motor 22 is started by the controller, and the output shaft at the bottom of the dual-axis motor 22 drives the polishing disc 23 to rotate. At the same time, the height of the polishing disc 23 is adjusted by the lifting structure. The electric push rod 24 in the lifting structure is activated, pushing the horizontal plate 25 to move up and down, which in turn drives the mounting bracket 21 and the polishing disc 23 to move up and down, so that the polishing disc 23 contacts the surface of the glass lens and performs the polishing operation. The output shaft at the top of the dual-axis motor 22 drives the worm gear 47 to rotate. Due to the worm gear 47 and the worm wheel 46 mesh with each other, driving the transmission gear 43 and driven gear 44 to rotate inside the pump casing 42, forming a working principle similar to a gear pump. Water in the water tank 412 is drawn into the pump casing 42 through the extraction pipe 411, and then pressurized and transported to the three-way pipe 48 to divide the water into two paths. One path is transported through the delivery pipe 413 to the installation pipe 49, and then sprayed out through multiple nozzles 410 that are evenly distributed and inclined outside the installation pipe 49 to rinse the sewage and debris mixture accumulated on the inclined plate 32, causing it to flow to the bottom of the cleaning tank 31. The other path is sprayed directly onto the grinding disc 23 and the surface of the glass lens through the rinsing spray pipe 414 to cool and rinse the grinding area and wash away the debris generated during grinding. The sludge pump is started by the controller, and the sludge pump pumps the sewage and debris mixture after rinsing in the cleaning tank 31 to the recovery tank 6 for centralized collection and treatment.
