Description

Technical Field

[0001] The present invention relates to the technical field of optical filter processing, in particular to an arc angle grinding device for optical filter processing. Background Art

[0002] Optical filters are key components in optical systems that selectively transmit or emit specific wavelengths of light. They are widely used in photography, medical equipment, laser technology, and spectral analysis. Because filters are made of plastic or glass with a special dye added, a red filter only allows red light to pass through. Glass, with a transmittance similar to that of air, allows all colored light to pass through, so it's considered transparent. However, when dyed, the filter's molecular structure changes, and its refractive index also changes, altering the ability of certain colors to pass through. For example, a beam of white light passing through a blue filter emits a blue beam, while very little green and red light is absorbed by the filter. Therefore, the filter's molecular structure and refractive index directly affect its performance. Therefore, to ensure the performance stability and optical precision of optical filters, the quality of their edges and corners is particularly important. Corner polishing is a critical process in filter manufacturing, directly affecting the filter's assembly accuracy, optical performance, and mechanical strength.

[0003] Traditional optical filter arc angle grinding mainly relies on manual operation or semi-automatic equipment. Manual grinding is labor-intensive and can only process a small number of filters at a time, which is difficult to meet mass production needs. Manual operation is prone to irregular arc angle shapes due to force and angle deviations, which will affect the assembly matching and optical performance of the filter. At the same time, when semi-automatic equipment grinds the arc angle of the filter, it is necessary to manually load, grind, and unload the filter, and then continue to load, grind, and unload another filter. The loading and unloading process is time-consuming, which makes the processing efficiency of the optical filter low. To this end, we propose an arc angle grinding device for optical filter processing to solve the above-mentioned problems of long time consumption, low processing efficiency and difficulty in meeting mass production needs.

[0029] like Figures 1 to 5 As shown, in one embodiment of the present invention, a device for grinding arc angles for processing optical filters is provided, comprising a support base 1. Four support rods 2 are fixedly connected at equal intervals to the top of the support base 1, and the ends of the four support rods 2 are fixedly connected to an operating table 3. Four base plates 18 are provided at equal intervals on the top of the operating table 3, and the four base plates 18 move in a circle along the center point of the operating table 3. The top of the base plate 18 is rotatably connected to a transmission shaft 19 via a bearing, and a circular plate 20 is fixedly connected to the top of the transmission shaft 19. A material storage plate 21 is detachably connected to the top of the circular plate 20. Material discharge troughs 22 are provided at equal intervals on the top of the material storage plate 21, and optical filters are fitted in the material discharge troughs 22. A support frame 4 is fixedly connected to the top of the operating table 3, and a mounting rod 8 is fixedly connected to the end of the support frame 4. A grinding head 34 for grinding the arc angles of the optical filter is mounted on the bottom of the mounting rod 8. A second electric push rod 11 is fixed to the bottom of the operating table 3, and the piston rod end of the second electric push rod 11 passes through the operating table 3 and is connected to the support plate 12. A plurality of connecting ports 23 are opened at the bottom of the storage plate 21, and the plurality of connecting ports 23 are respectively located below the bottom of the corresponding discharge trough 22, and the support plate 12 is located directly below the connecting ports 23.

[0030] The second electric push rod 11 is fixedly installed at the bottom of the operating table 3. The second electric push rod 11 can control the lifting and lowering of the support plate 12. The support plate 12 is located below the connecting port 23. When the support plate 12 is raised, it can pass through the connecting port 23 to lift the optical filter inside the discharge trough 22 to a set height. This height is at the height of the grinding head 34, which is convenient for the grinding head 34 to grind its arc corners. A fixing block 27 is integrally connected to the top of the circular plate 20, and a fixing groove is provided in the top center of the storage plate 21. The fixing block 27 slides through the fixing groove. A mounting groove 28 is symmetrically provided in the fixing block 27, and a spring 29 is fixed in the mounting groove 28. A tongue-shaped block 30 is fixed to the end of the spring 29, and the end of the tongue-shaped block 30 passes through the fixed block 27. The bottom of the tongue-shaped block 30 contacts the top of the storage plate 21. A sliding groove 31 is symmetrically provided on the top of the fixed block 27. A slide plate 32 is fixed to the top of one end of the tongue-shaped block 30 located inside the mounting groove 28, and the slide plate 32 is slidably connected in the slide groove 31, and the top of the slide plate 32 passes through the fixed block 27.

[0031] The storage plate 21 is provided with a plurality of discharge slots 22 for storing the optical filters to be polished at an even distance. The storage plate 21 can be installed on the circular plate 20. During installation, it is only necessary to connect the fixing slots on the storage plate 21 to the fixing blocks 27 on the circular plate 20. During the process of inserting the fixing blocks 27 into the fixing slots of the storage plate 21, the two tongue-shaped clamping blocks 30 slide out under the action of the springs 29, so that the storage plate 21 is firmly installed on the top of the circular plate 20. When all the optical filters on the storage plate 21 are polished, the storage plate 21 storing the optical filters is removed. During disassembly, it is only necessary to slide the two slides 32 toward each other at the same time, so that the tongue-shaped clamping blocks 30 enter the installation slots 28, and then directly lift and pull out the storage plate 21 through the handle 33, so that all the optical filters on the storage plate 21 can be collectively transferred to the next process for operation.

[0032] A first electric push rod 5 is fixed to the top of the support frame 4, and the end of the piston rod of the first electric push rod 5 passes through the support frame 4 and is fixed to a rotating motor 6. The end of the output shaft of the rotating motor 6 is fixed to a pressure plate 7. The pressure plate 7 is located directly above the support plate 12. The end of the piston rod of the second electric push rod 11 is connected to the support plate 12 through a bearing. Anti-slip pads are provided on the top of the support plate 12 and the bottom of the pressure plate 7. The diameter of the connecting port 23 is smaller than the diameter of the discharge trough 22. When the second electric push rod 11 works and raises the optical filter to a set height through the support plate 12, the first electric push rod 5 works to push the rotary motor 6 down, and the pressure plate 7 fixed to the output end of the rotary motor 6 is pressed against the top of the optical filter, and the anti-slip pads provided at the bottom of the pressure plate 7 and the top of the support plate 12 can increase friction, thereby fixing the position of the optical filter. The support plate 12 and the second electric push rod 11 are rotatably connected. When the rotary motor 6 drives the pressure plate 7 to rotate, the optical filter and the support plate 12 rotate accordingly. During the rotation of the optical filter, the grinding head 34 can perform all-round grinding of the arc angle of its outer axis.

[0033] The bottom of the operating table 3 is rotatably connected to a transmission rod 14 via a bearing. A drive motor 13 is fixedly mounted on the top of the support base 1, and the end of the output shaft of the drive motor 13 is fixedly connected to the transmission rod 14. Four fixed rods 15 are fixedly connected to the outside of the transmission rod 14 at equal intervals, and a vertical rod 16 is fixedly connected to the top of the fixed rod 15. An annular connecting groove 17 is provided at the top of the operating table 3. The four vertical rods 16 slide through the annular connecting groove 17 and are respectively connected to the central axis of the four bottom plates 18. When the drive motor 13 is working, it drives the transmission rod 14 to rotate. When the transmission rod 14 rotates, the four fixed rods 15 rotate accordingly. The fixed rods 15 drive the vertical rods 16 to slide inside the annular connecting groove 17. The vertical rods 16 pull the bottom plate 18 to slide along the annular connecting groove 17 on the operating table 3, thereby moving the positions of the four bottom plates 18. In turn, the positions of the four storage plates 21 are moved through the bottom plates 18. Annular rolling grooves 35 are provided on the top of the operating table 3 , both outside and inside the annular connecting groove 17 . Two balls 36 are embedded in the bottom of the bottom plate 18 , and the two balls 36 are respectively connected in rolling engagement in the two annular rolling grooves 35 .

[0034] The placement of ball bearings 36 at the bottom of base plate 18 allows them to move within annular rolling grooves 35 as base plate 18 slides along annular connecting grooves 17, reducing friction losses during circular motion. A driven bevel gear 26 is fixedly attached to the outside of transmission shaft 19. A drive motor 24 is fixedly mounted on the top of base plate 18, with a driving bevel gear 25 fixedly attached to the end of the drive motor 24's output shaft. The driving bevel gear 25 meshes with the driven bevel gear 26. A linear module 9 is mounted at the bottom of mounting rod 8, and the bottom of the linear module 9's movable platform is fixedly attached to a grinding head 34. The grinding head 34 has an arc-shaped groove on its outside that aligns with the optical filter's arc angle. The outer portion of grinding head 34 is provided with a U-shaped groove. During grinding, the outer side of the optical filter lies within the U-shaped groove, and the arc angles of the upper and lower ends of the optical filter's outer edge align with the groove's interior, thereby achieving polishing of the optical filter's arc angle. A carrying handle 33 is symmetrically provided on the top of the material storage plate 21 .

[0035] When the present invention is used, the optical filter to be polished is placed in the discharge groove 22 on the storage plate 21. After placement, the storage plate 21 is installed on the circular plate 20. During installation, the fixing groove on the storage plate 21 is connected to the fixing block 27 on the circular plate 20. During the process of inserting the fixing block 27 into the fixing groove of the storage plate 21, the two tongue-shaped clamping blocks 30 slide out under the action of the spring 29, so that the storage plate 21 is firmly installed on the top of the circular plate 20. After the storage plate 21 is installed, the control system provided in the device controls the drive motor 13 to work, and the drive motor 13 drives the fixing rod 15 to rotate a certain angle each time, so that the storage plate 21 Located just below the top of the support frame 4, the second electric push rod 11 works to push the support plate 12 up, and the support plate 12 lifts the optical filter in the discharge trough 22 to the height of the grinding head 34. Then the first electric push rod 5 works to press the pressure plate 7 downward on the top of the optical filter, and drives the grinding head 34 to the filter through the linear module 9. At this time, the outer edge of the filter is located in the arc groove of the grinding head 34, and the arc angles of the top and bottom ends of the filter are in contact with the inner wall of the arc groove. The cooperation of the support plate 12 and the pressure plate 7 fixes the position of the optical filter. At this time, the rotating motor 6 works to drive the optical filter to rotate, and the arc of the filter is rotated during the rotation. After the filter is polished, the second electric push rod 11 and the first electric push rod 5 stop working, and the polished filter is placed back in the discharge trough 22, and then the driving motor 24 is driven to drive the active bevel gear 25 to rotate, and the material storage plate 21 is rotated through the meshing connection between the active bevel gear 25 and the driven bevel gear 26, and the material storage plate 21 is controlled to rotate a certain angle so that the next filter to be polished is located directly under the pressure plate 7, and the filter is continued to be polished in the above manner. After all the filters on the material storage plate 21 at this position are polished, the driving motor 13 is driven to drive the operating table 3 to rotate. The angle is set so that the next storage plate 21 storing the arc-angle filter to be polished is located at the position of the support frame 4, and the arc angle of the filter on the storage plate 21 is continued to be polished; the storage plate 21 where the polished filter is located is disassembled. When disassembling, it is only necessary to move the two slides 32 toward each other at the same time, so that the tongue-shaped block 30 enters the installation groove 28, and then the storage plate 21 is directly lifted and pulled out by the handle 33, and the polished filter on the storage plate 21 is directly transferred to the next process operation. In short, the present invention has the advantages of greatly reducing the time for manual loading and unloading, realizing continuous batch processing, significantly improving production efficiency and facilitating disassembly and installation.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
