DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a core drilling machine for optical lens processing, including a machine body 1. The machine body 1 serves as the load-bearing structure of the entire device, providing installation and operating space for internal components. On both the left and right sides inside the machine body 1, there are fixedly connected support frames 2. The support frames 2 play a role in supporting and fixing subsequent connected components, ensuring the accuracy and stability of the installation positions of various components. On the sides of the two support frames 2 away from each other, there are fixedly connected cylinders 3. The cylinders 3 serve as power sources and can provide power for linear motion of subsequent components through the telescopic movement of their output ends. The output end of the cylinder 3 is fixedly connected with a mounting block 4. The mounting block 4 is used for installing and fixing a servo motor 5, transmitting the power of the cylinder 3 to the servo motor 5. On the top of the mounting block 4, there is fixedly connected a servo motor 5. The servo motor 5 can precisely control the output rotation speed and direction, so that the lens can rotate during the lens processing. The output end of the servo motor 5 is fixedly connected with a vacuum suction nozzle 6. The vacuum suction nozzle 6 utilizes the principle of vacuum adsorption and can firmly adsorb the optical lens, ensuring the stability of the lens during processing. In the middle side inside the machine body 1, there is fixedly connected a grinding platform 8. The grinding platform 8 is the main working area for grinding optical lenses, providing an installation basis for grinding components, filtering components, and fixing components. On the top of the grinding platform 8, there is installed a grinding component, which is used for grinding the optical lens to improve the flatness and smoothness of the lens surface. Inside the grinding platform 8, there is installed a filtering component, which can filter the debris and impurities generated during grinding to prevent them from mixing into the coolant circulation system. On the inner wall of the grinding platform 8, there is installed a fixing component, which is used for fixing the filter screen 23 in the filtering component and facilitating the disassembly of the filter screen 23;

[0033] Refer to Figure 3, The conveying component includes a cylinder body 11, and the cylinder body 11 is fixedly connected to the inner wall of the left support frame 2 to ensure the stability of the cylinder body 11 during operation. A piston 12 is slidably connected inside the cylinder body 11. The reciprocating sliding of the piston 12 inside the cylinder body 11 can achieve the suction and extrusion operations of media such as coolant. A connecting rod 13 is fixedly connected to the top of the piston 12 and penetrates through the top of the cylinder body 11. The connecting rod 13 is used to transmit the extrusion movement of the extrusion plate 14 to the piston 12 to drive the piston 12 to slide. A top of the connecting rod 13 is fixedly connected to an extrusion plate 14. The extrusion plate 14 moves up and down under the action of the eccentric shaft 7, and then drives the piston 12 to move. A first spring 15 is sleeved on the outer wall of the connecting rod 13, and the first spring 15 plays a role in buffering and resetting. When the extrusion plate 14 is not subject to external force, under the action of the first spring 15, the piston 12 can return to the initial position. An electromagnetic check valve 16 and a check valve 18 are fixedly connected to the bottom edge of the cylinder body 11. The electromagnetic check valve 16 controls the inflow of coolant and only allows coolant to enter the cylinder body 11 when it is energized and meets certain pressure conditions. The check valve 18 ensures that the coolant can only flow out of the cylinder body 11 and will not flow back. A water inlet pipe 17 is fixedly connected to the bottom of the electromagnetic check valve 16, and the water inlet pipe 17 introduces the coolant in the water storage tank 27 into the cylinder body 11. A water outlet pipe 19 is fixedly connected to the bottom of the check valve 18, and the water outlet pipe 19 conveys the coolant extruded from the cylinder body 11 to the nozzle 21.

[0034] Refer to Figure 4 , The grinding component includes a grinding motor 9, and the grinding motor 9 is fixedly connected to the top of the grinding platform 8. The grinding motor 9 serves as the power source of the grinding component and provides the power for the high-speed rotation of the grinding wheel 10. An output end of the grinding motor 9 is fixedly connected to a grinding wheel 10. The grinding wheel 10 rotates at high speed under the drive of the grinding motor 9 to grind the optical lens fixed by two vacuum suction nozzles 6 on the grinding platform 8.

[0035] Refer to Figure 5 , The filtering component includes a filter screen 23. The filter screen 23 can effectively intercept the debris and impurities generated during the grinding process. The filter screen 23 is installed in the middle of the grinding platform 8. When the coolant mixture flowing from the grinding area passes through the filter screen 23, the debris and impurities are filtered out, and the clean coolant continues to be recycled or processed subsequently.

[0036] Refer to Figure 5 , The fixing component includes two pull rods 24. The outer walls of the pull rods 24 are slidably connected to the inner wall of the grinding platform 8. The pull rods 24 are used to slide to achieve the fixing and disassembly effects of the filter screen 23. A limiting block 25 is fixedly connected to the outer wall of the pull rod 24. The limiting block 25 limits the sliding range of the pull rod 24 to prevent the pull rod 24 from sliding excessively and detaching from the grinding platform 8. A second spring 26 is sleeved on the outer wall of the pull rod 24, and the second spring 26 is used to provide elastic force to ensure the stability of the fixing of the pull rod 24.

[0037] Refer to Figure 1 and Figure 3 Inside the bottom wall of the machine body 1, a water storage tank 27 is fixedly connected. The water storage tank 27 is used to store coolant and provide coolant supply for the entire processing process. One end of the water inlet pipe 17 away from the electromagnetic check valve 16 is arranged inside the water storage tank 27, so that the coolant in the water storage tank 27 can enter the inside of the cylinder body 11 of the conveying assembly through the water inlet pipe 17.

[0038] Refer to Figures 2 - 4 On the top of the grinding platform 8, a mounting plate 20 is fixedly connected. The mounting plate 20 is used to mount the nozzle 21 to ensure the accurate mounting position of the nozzle 21. On one side of the mounting plate 20 close to the grinding wheel 10, a nozzle 21 is fixedly connected. The nozzle 21 sprays the coolant conveyed from the water outlet pipe 19 onto the processing parts of the grinding wheel 10 and the optical lens, playing a role in cooling and lubrication. The end of the water outlet pipe 19 away from the check valve 18 is communicated with the nozzle 21 to ensure that the coolant can be smoothly conveyed from the cylinder body 11 to the nozzle 21 through the water outlet pipe 19.

[0039] Refer to Figure 2 On the shaft of the output end of the left servo motor 5, an eccentric shaft 7 is fixedly connected. The eccentric shaft 7 rotates with the rotation of the output shaft of the servo motor 5, and the position of the eccentric shaft 7 can be adjusted at the position of the servo motor 5. The protruding part of the eccentric shaft 7 is in contact with the top of the pressing plate 14. When the eccentric shaft 7 rotates, its protruding part intermittently presses the pressing plate 14, so that the pressing plate 14 drives the piston 12 to reciprocate in the cylinder body 11, realizing the suction and extrusion of the coolant.

[0040] Refer to Figure 1 、 Figure 4 and Figure 5 On the surface of the grinding platform 8, a plurality of water guide grooves 22 are provided. The water guide grooves 22 are used to guide the coolant mixture flowing down from the grinding area to the filter screen 23 for convenient filtration. A water pipe is arranged between the bottom of the grinding platform 8 and the water storage tank 27, and the coolant filtered by the filter screen 23 is retransported back to the water storage tank 27 through the water pipe to realize the recycling of the coolant. The pull rod 24 passes through the grinding platform 8 and is engaged with the filter screen 23 to ensure the stability of the fixation of the filter screen 23.

[0041] Working principle: When the lens needs to be cored, one side of the lens is fixed to the output end of the servo motor 5 through the vacuum nozzle 6. Then, the two cylinders 3 are started synchronously, so that the cylinder 3 pushes the mounting block 4 to slide, and further drives the two servo motors 5 to slide relative to each other, thereby driving the two vacuum nozzles 6 to slide relative to each other, and fixing the lens through the two vacuum nozzles 6. Then, the grinding motor 9 and the servo motor 5 are started. When the grinding motor 9 rotates, it will drive the grinding wheel 10 to rotate to grind the lens. When the servo motor 5 rotates, it will drive the vacuum nozzle 6 to rotate, thereby driving the lens to rotate, ensuring that there are no dead angles in the grinding.

[0042] When the servo motor 5 rotates, the eccentric shaft 7 is also driven to rotate. When the eccentric shaft 7 rotates, the extrusion plate 14 is driven to slide downward through the eccentric motion. When the extrusion plate 14 slides downward, the piston 12 is driven to slide inside the cylinder 11 through the transmission action of the connecting rod 13, thereby squeezing out the coolant inside the cylinder 11 and delivering it to the position of the nozzle 21 through the outlet pipe 19, and spraying it out to cool the lens being polished. In the process of the extrusion plate 14 sliding downward, the first spring 15 is also squeezed. When the eccentric shaft 7 no longer squeezes the extrusion plate 14, the external force disappears, and the first spring 15 releases the stored potential energy, thereby pushing the extrusion plate 14 to reset, and further driving the piston 12 to reset. When the piston 12 resets, the coolant is extracted from the water tank 27 and delivered to the inside of the cylinder 11 to prepare for the next spraying.

[0043] The used coolant will be transported to the inside of the grinding platform 8 through the water guide groove 22 on the top of the grinding platform 8. At this time, the used coolant will be filtered through the filter 23 inside the grinding platform 8. After the filter 23 has been used for a long time, the two pull rods 24 can be pulled to disengage the pull rods 24 from the engagement state with the filter 23. Then, the filter 23 is pulled out and cleaned, and then put back into the grinding platform 8. The second spring 26 pushes the limit block 25 to slide, which further drives the pull rod 24 to slide, thereby fixing the filter 23.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
