Abstract
Description
Technical Field
[0001] This invention relates to the field of polishing equipment technology, and in particular to a lens polishing device for manufacturing optical instruments. Background Technology
[0002] In optical instrument manufacturing, the surface accuracy and quality of lenses directly determine the imaging performance of optical instruments. Among them, the polishing of circular plane mirrors is a key process, and the "collapse" and "curving" of the lens edge area during polishing are long-standing and difficult-to-overcome technical problems. The inner (near center) and outer (near edge) regions of a lens differ in curvature, linear velocity, and material removal characteristics. However, existing overall polishing solutions cannot provide differentiated polishing parameters (such as pressure, dwell time, and motion trajectory) for the inner and outer regions, resulting in parameter settings having to be compromised. To ensure the accuracy of the central region, the polishing effect of the edge region is often sacrificed, which can easily lead to excessive material removal at the edge, resulting in edge collapse, or insufficient material removal, resulting in edge curling, making it difficult to guarantee the polishing accuracy of the lens edge. Summary of the Invention
[0003] The purpose of this invention is to provide a lens polishing device for optical instrument manufacturing, which addresses the problem of edge collapse or warping caused by the inability to provide differentiated polishing during the polishing process due to the difference between the inner and outer ring areas of the lens.
[0004] To achieve the above objectives, the present invention employs the following techniques: An optical instrument manufacturing lens polishing device includes an adsorption head and a plane mirror adsorbed thereon, and further includes: a housing and a fixing plate fixed inside it, a bracket fixed on the fixing plate, an inner ring polishing component mounted on the bracket, and an outer ring polishing component on one side of the fixing plate; The inner ring grinding component includes a motor fixedly connected to the mounting bracket and a straight plate fixed on the mounting bracket. A connecting pipe is fixed to one side of the straight plate, and a circular plate with a track groove is fixed to the end of the connecting pipe away from the straight plate. A limit component is fixed to the output end of the motor through a transmission shaft, and a grinding component is provided on the limit component. The outer ring grinding component includes a connecting rod, a second track groove is provided on the fixed plate, a driving component is provided on one side of the fixed plate, a U-shaped plate is fixed at the upper end of the connecting rod, a second grinding head concentric with the connecting rod is fixed on the upper horizontal part of the U-shaped plate through a mounting shaft, and a chamfering component is provided on the vertical part of the U-shaped plate. The set motor and limiting component enable the grinding assembly to perform spiral trajectory grinding on the inner circle of the track groove pair. The drive component drives the connecting rod to move in the inner cavity of the track groove, so that the grinding head two performs spiral trajectory grinding on the outer ring.
[0005] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: The limiting component includes a U-shaped block fixedly connected to the drive shaft. The two horizontal parts of the U-shaped block are provided with limiting grooves. An installation block is fixed on the limiting groove. A second bevel gear is rotatably mounted on the installation block via a rotating shaft. A first bevel gear that meshes with the second bevel gear is fixed on the connecting pipe.
[0006] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: The vertical part of the U-shaped block is fixed with a support frame, and a limit tube is rotatably installed on the support frame. The limit tube and the rotating shaft are connected by a synchronous belt group.
[0007] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: The grinding assembly includes a movable rod movably installed in the inner cavity of the limiting groove, an L-shaped plate fixed on the movable rod that slides on the U-shaped block, and a set of meshing bevel gears mounted on the L-shaped plate.
[0008] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: The bevel gear three in the horizontal direction is fixed with a grinding head one that is concentric with the movable rod through a mounting shaft, and a cross rod that is slidably connected to the inner cavity of the limiting tube is provided on one side of the bevel gear three in the vertical direction.
[0009] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: The driving component includes a fixed tube fixedly connected to a fixed plate, a collar rotatably mounted on the outer surface of the fixed tube, a toothed ring fixed on the outer surface of the collar, a driving plate with a driving groove fixed on the outer surface of the collar, and a connecting rod movable within the driving groove.
[0010] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: A mounting plate is fixed to the outer surface of the fixed tube, and a second motor is fixed to the mounting plate. A first gear that meshes with a gear ring is fixed to the output end of the second motor.
[0011] Further description of a lens polishing apparatus for manufacturing optical instruments as described above: The chamfering assembly includes a grooved plate fixedly connected to the vertical part of the U-shaped plate. A vertical rod is movably installed in the inner cavity of the grooved plate. A sliding groove adapted to the vertical rod is provided on the fixed plate. A telescopic rod is fixed on the vertical rod. A fixing ring is fixed on the telescopic rod. A chamfering head is fixed to the output end of the telescopic rod through a connecting rod.
[0012] In summary, the beneficial effects of this invention, which employs the aforementioned technology for lens polishing in optical instrument manufacturing, are as follows: 1. This device divides the lens surface into two independent control areas: an "inner circle" and an "outer ring." The inner and outer ring grinding components grind these areas separately, allowing for different grinding parameters to be used for each. This targeted correction of surface shape errors in specific areas effectively prevents edge collapse or warping. Simultaneously, through the designated track grooves one and two, grinding heads one and two, concentric with the movable rod and the connecting rod, move along an Archimedean spiral trajectory. Both the inner circle and outer ring are ground using this trajectory, ensuring uniform force and consistent material removal at the edges. This fundamentally solves the problem of edge collapse and warping caused by parameter mismatch in traditional grinding, thus improving grinding accuracy.
[0013] 2. Through the cooperation between the limiting component and the grinding assembly, the grinding head rotates simultaneously with its spiral trajectory, ensuring that different parts of the grinding head contact the lens, preventing excessively rapid local wear and extending its service life. Simultaneously, the change in relative motion direction breaks up single grinding marks and reduces surface roughness. The revolution of the limiting component drives the second bevel gear to rotate around the fixed first bevel gear, generating rotational power. Through the synchronous belt and crossbar transmission, this ultimately drives the grinding head to rotate at high speed while simultaneously revolving around the lens.
[0014] 3. The chamfering component is set up so that the edge of the lens is chamfered while the grinding head is grinding along the spiral trajectory, so as to avoid sharp edges or defects; the U-shaped plate of the outer ring grinding component is equipped with a chamfering component, whose chamfering head rotates with the component and simultaneously chamfers the edge of the lens, and automatically avoids interference with the grinding head through the telescopic structure.

[0017] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a lens grinding device for manufacturing optical instruments according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] like Figure 1 As shown, a lens polishing device for manufacturing optical instruments includes an adsorption head 14 and a plane mirror 12 adsorbed on it. The adsorption head 14 is fixed in the inner cavity of the housing 10 by a support platform. The plane mirror 12 is adsorbed on the upper end by connecting an air pump. The device also includes the housing 10 and a fixing plate 11 fixed inside it. A bracket 13 is fixed on the fixing plate 11. An inner ring polishing component 20 is mounted on the bracket 13. An outer ring polishing component 30 is provided on one side of the fixing plate 11. The polishing area on the lens surface is divided into two regions: an "inner circle" and an "outer ring." The inner ring polishing component 20 is used to polish the "inner circle" region, and the outer ring polishing component 30 is used to polish the "outer ring" region. The entire lens surface is considered as two independent "control units." By adjusting the polishing parameters (such as pressure, residence time, and polishing fluid concentration) of the inner circle and outer ring respectively, surface shape errors in specific areas can be corrected in a targeted manner, precisely solving the problems of edge collapse or edge warping.
[0019] like Figure 2 and Figure 3 As shown, the inner ring grinding component 20 includes a motor 21 fixedly connected to the mounting bracket and a straight plate 22 fixed on the mounting bracket. A connecting pipe 23 is fixed to one side of the straight plate 22. The connecting pipe 23 is concentric with the plane mirror 12. A circular plate 26 with a trajectory groove 25 is fixed to the end of the connecting pipe 23 away from the straight plate 22. The trajectory groove 25 is an Archimedean spiral trajectory. A limit component 27 is fixed to the output end of the motor 21 through a drive shaft 29. The drive shaft 29 is fixed to the output end of the motor 21. 29 passes through the connecting pipe 23 and is fixedly connected to the horizontal part under the limiting component 27, so that the motor 21 can drive the limiting component 27 to rotate, and the circular plate 26 is located in the inner cavity of the limiting component 27. The limiting component 27 is provided with a grinding component 28 that is adapted to the track groove 25. Under the action of the limiting component 27, the grinding component 28 moves along the track groove 25 to grind the inner circle. The rotation speed of the grinding component 28 can be controlled by the motor 21, so that the grinding speed can be adjusted. The Archimedean spiral is a continuous and smooth curve. Grinding heads using this trajectory do not experience sudden changes in direction during movement, avoiding the pauses and turning marks caused by linear reciprocating motion. This prevents impact and vibration on the lens, resulting in a more uniform surface texture. The Archimedean spiral expands outward from the center, ensuring a uniform residence time of the grinding head on the lens surface, thus achieving even material removal and preventing localized over- or under-grinding.
[0020] like Figure 3 and Figure 4As shown, the outer ring grinding component 30 includes a connecting rod 32. A second track groove 321 adapted to the connecting rod 32 is provided on the fixing plate 11. The second track groove 321 is an Archimedean spiral trajectory, so that the movement trajectory of the connecting rod 32 is an Archimedean spiral trajectory. A driving component 31 for driving the connecting rod 32 is provided on one side of the fixing plate 11. The driving component 31 drives the connecting rod 32 to move in the cavity of the second track groove 321. A U-shaped plate 33 is fixed at the upper end of the connecting rod 32. The lower horizontal part of the U-shaped plate 33 is fixedly connected to the connecting rod 32. A second grinding head 35 concentric with the connecting rod 32 is fixed on the upper horizontal part of the U-shaped plate 33 through a mounting shaft, so that the movement trajectory of the second grinding head 35 is the same as the movement trajectory of the connecting rod 32, and the outer ring area of the plane mirror 12 is ground. A chamfering component 34 is provided on the vertical part of the U-shaped plate 33.
[0021] In the outer ring area, the designed spiral trajectory groove 321 reduces edge warping or collapse caused by abrupt changes in the direction of movement. Simultaneously, the spiral trajectory ensures that the grinding head has sufficient dwell time in the edge area, thereby uniformly removing material.
[0022] Through the limiting component 27 connected to the motor 21 and the drive shaft 29, as the motor 21 drives the limiting component 27 to rotate, the grinding assembly 28, in conjunction with the trajectory groove 25 on the circular plate 26, performs spiral trajectory grinding on the inner circle. The driving component 31 drives the connecting rod 32 to move within the trajectory groove 321, causing the grinding head 35 to perform spiral trajectory grinding on the outer ring. By using two separately controlled grinding systems, the lens can be ground in sections, effectively controlling uneven grinding at the lens edges that could lead to edge collapse or warping. Furthermore, by using different parameters for different areas, optimal removal efficiency can be achieved simultaneously on both the inner and outer rings, shortening processing time. The continuity of the spiral motion avoids the pauses and turning marks caused by linear reciprocating motion, resulting in a more uniform surface texture.
[0023] The inner and outer rings can use different helical parameters, such as starting radius and pitch, to optimize for their different characteristics. For example, the inner ring can use a smaller pitch to increase grinding density and improve surface accuracy; the outer ring can use a larger pitch to improve efficiency and prevent edge collapse.
[0024] like Figure 5 and Figure 6As shown, the limiting component 27 includes a U-shaped block 271 fixedly connected to the drive shaft 29. The drive shaft 29 is fixedly connected to the horizontal part on the lower side of the U-shaped block 271, so that the drive shaft 29 drives the U-shaped block 271 to rotate. Limiting grooves 272 are provided on both horizontal parts of the U-shaped block 271. The limiting grooves 272 communicate with the inner cavity of the first track groove 25. A mounting block 274 is fixed on the limiting groove 272. A bevel gear 275 is rotatably mounted on the mounting block 274 via a rotating shaft 273. 273 is rotatably mounted on mounting block 274. One end of rotating shaft 273 near mounting block 274 is fixedly connected to bevel gear 275. Bevel gear 24 that meshes with bevel gear 275 is fixed on connecting pipe 23. Bevel gear 275 rotates with U-block 271 through mounting block 274 which is fixed to U-block 271. During the rotation of U-block 271, bevel gear 275 meshes with bevel gear 24, causing bevel gear 275 to rotate. Next, a support frame 277 is fixed to the vertical part of the U-shaped block 271. A limit tube 276 is rotatably installed on the support frame 277. The rotating shaft 273 is also rotatably engaged with the support frame 277. The limit tube 276 and the rotating shaft 273 are connected by a synchronous belt group 278. The synchronous belt group 278 includes a synchronous pulley fixed to the limit tube 276 and the rotating shaft 273 and a synchronous belt connected to the two synchronous pulleys, so that the rotating shaft 273 and the limit tube 276 rotate together.
[0025] like Figure 6 and Figure 7 As shown, the grinding assembly 28 includes a movable rod 281 movably installed in the inner cavity of the limiting groove 272. As the U-shaped block 271 rotates, the movable rod 281 moves along the inner cavity of the track groove 25. An L-shaped plate 282 that slides on the U-shaped block 271 is fixed on the movable rod 281. The horizontal part of the L-shaped plate 282 is slidably connected to the U-shaped block 271. A set of meshing bevel gears 284 is installed on the L-shaped plate 282. Next, the horizontally oriented bevel gear 284 is fixed with a grinding head 283 concentric with the movable rod 281 via a mounting shaft. Both the grinding head 283 and the movable rod 281 move in an Archimedean spiral trajectory to grind the inner circle of the plane mirror 12. On one side of the vertically oriented bevel gear 284, a cross rod 285 is slidably connected to the inner cavity of the limiting tube 276. The inner cavity of the limiting tube 276 has a cross groove adapted to the cross rod 285, allowing the limiting tube 276 to drive the cross rod 285 to rotate, thereby causing the set of bevel gears 284 to rotate. Simultaneously with the spiral motion of the grinding head 283, the grinding head 283 rotates. This rotation ensures that different parts of the grinding head 283 contact the mirror, preventing excessively rapid wear in certain areas and extending its service life. Furthermore, the rotation increases the variation in the relative motion direction between the grinding head 283 and the workpiece, helping to break up single grinding marks, thereby reducing surface roughness and obtaining a more uniform surface texture.
[0026] like Figure 8 and Figure 10 As shown, the driving component 31 includes a fixed tube 311 fixedly connected to the fixed plate 11. The adsorption head 14 passes through the inner cavity of the fixed tube 311, with its upper end positioned above the fixed plate 11. A collar 315 is rotatably mounted on the outer surface of the fixed tube 311. A toothed ring 314 is fixed on the outer surface of the collar 315. A driving plate 316 with a driving groove 317 is fixed on the outer surface of the collar 315. The connecting rod 32 moves within the inner cavity of the driving groove 317. As the driving plate 316 rotates with the collar 315, the connecting rod 32 within the inner cavity of the driving groove 317 moves along the second track groove 321 in an Archimedean spiral motion, causing the second grinding head 35, which is concentric with the connecting rod 32, to grind the outer ring area of the plane mirror 12. A mounting plate is fixed to the outer surface of the fixed tube 311, and a motor 312 is fixed to the mounting plate. A first gear 313 that meshes with the gear ring 314 is fixed to the output end of the motor 312. The first gear 313 drives the gear ring 314 to rotate through the motor 312, thereby driving the drive plate 316 to rotate through the collar 315. The motor 312 can control the rotation speed of the drive plate 316, thereby controlling the grinding speed of the grinding head 35. This can solve the problem of uneven edge grinding and prevent edge collapse or warping.
[0027] like Figure 9 and Figure 10 As shown, the chamfering assembly 34 includes a grooved plate 341 fixedly connected to the vertical part of the U-shaped plate 33. A vertical rod 342 is movably installed in the inner cavity of the grooved plate 341. A sliding groove 3421 adapted to the vertical rod 342 is provided on the fixed plate 11. A telescopic rod 343 is fixed on the vertical rod 342. The telescopic rod 343 is located at the upper end of the vertical rod 342. A fixing ring 344 is fixed on the telescopic rod 343. The fixing ring 344 is installed in the telescopic part of the telescopic rod 343. A chamfering head 345 is fixed to the output end of the telescopic rod 343 through a connecting rod. The chamfering head 345 is used to chamfer the edge of the lens. like Figure 11 As shown, the groove plate 341 rotates with the connecting rod 32 via the U-shaped plate 33, while the vertical rod 342 slides in the inner cavity of the sliding groove 3421. The chamfering head 345 rotates continuously at the edge of the plane mirror 12 via the fixing ring 344, grinding the edge of the plane mirror 12. As the groove plate 341 rotates, the U-shaped plate 33 gradually moves closer to the fixing ring 344, which then pushes the fixing ring 344 to drive the telescopic part of the telescopic rod 343 to retract, preventing the chamfering head 345 from contacting the grinding head 35.
[0028] Working principle: This device is a lens polishing equipment for optical instrument manufacturing, mainly used for polishing circular lenses; When in use, place the plane mirror 12 on the upper end of the adsorption head 14 for adsorption and fixation, and then start the motor 1 21 and the motor 2 312 to make the grinding head 1 283 and the grinding head 2 35 grind the surface of the plane mirror 12 in sections. The grinding speed can also be controlled by controlling the motor 1 21 and the motor 2 312 to make the grinding uniform and prevent the center of the lens from bulging or sinking due to stress problems. During the process of the motor 21 driving the transmission shaft 29 to rotate, the U-shaped block 271 connected to the transmission shaft 29 rotates around the center of the track groove 25. At the same time, the movable rod 281 in the inner cavity of the limiting groove 272 moves in the inner cavity of the track groove 25, causing the grinding head 283, which is concentric with the movable rod 281, to perform Archimedes spiral trajectory motion. The motor 21 drives the transmission shaft 29 to rotate back and forth, so that the grinding head 283 grinds the inner circular area of the plane mirror 12. During the rotation of U-shaped block 271, bevel gear 275 rotates around bevel gear 24, causing bevel gear 275 to drive rotating shaft 273 to rotate. Through synchronous belt group 278, rotating shaft 273 and limiting tube 276 rotate together. Then, limiting tube 276 drives bevel gear 284 to rotate through cross rod 285 in the inner cavity, so that grinding head 283 rotates along the inner cavity of track groove 25 while rotating on its own axis.
[0029] Driven by the first gear 313 at the output end of the second motor 312, the gear ring 314 drives the collar 315 to rotate. The connecting rod 32 in the inner cavity of the drive groove 317 on the drive plate 316 moves along the second track groove 321. It is connected to the second grinding head 35, which is concentric with the connecting rod 32, through the U-shaped plate 33. The second grinding head 35 also moves along the track groove 321 to grind the outer ring area of the plane mirror 12. While the connecting rod 32 moves along the trajectory of the second track groove 321, the vertical rod 342 slides in the inner cavity of the sliding groove 3421 through the groove plate 341. The vertical rod 342 rotates around the center of the fixed tube 311, so that the chamfering head 345 connected to the fixed ring 344 chamfers the edge of the plane mirror 12. Then, as the U-shaped plate 33 gradually moves closer to the fixed ring 344, the U-shaped plate 33 will push the fixed ring 344 to retract the telescopic part of the telescopic rod 343, thus preventing the chamfering head 345 from contacting the grinding head 35.
