[0002] In optical calibration, it is often necessary to adjust the lens spacing. This usually requires grinding the lenses to adjust their thickness, thereby achieving the desired adjustment. Existing lens grinding equipment is typically complex in structure and mainly used for automated lens production.

[0046] Example

[0047] Reference Figure 1 As shown, this embodiment provides a lens polishing mechanism, including a frame 1, a clamping assembly 2, a pressure adjusting assembly 3, and a driving assembly 4. The bottom of the frame 1 is provided with a polishing area 11, which is used to fit against the lens 5 so that the lens 5 is polished during movement.

[0048] Reference Figure 2 , Figure 3 and Figure 4As shown, the clamping assembly 2 includes a gripper unit 21, a gripper shaft 22, and a gripper adjustment member 23. The gripper unit 21 is hinged to the gripper shaft 22, and three gripper units 21 are arranged around the axis of the gripper shaft 22. By driving the gripper unit 21 to swing around the hinge point, the multiple gripper units 21 can clamp or release the lens 5. By controlling the degree of swing of the gripper unit 21, it is possible to adapt to clamping lenses 5 of different sizes. It should be noted that in other embodiments, two gripper units 21 or more gripper units 21 may also be provided.

[0049] The gripper unit 21 is located above the grinding area 11. After the gripper unit 21 clamps the lens 5, it abuts the lens 5 against the grinding area 11, facilitating grinding of the lens 5. The gripper adjusting member 23 is movably mounted on the gripper shaft 22 along the axial direction of the gripper shaft 22. The gripper adjusting member 23 abuts against the gripper unit 21, and when the gripper adjusting member 23 moves along the axial direction of the gripper shaft 22, it drives the gripper unit 21 to swing. For example, when the gripper adjusting member 23 moves toward the direction closer to the lens 5, it drives the gripper unit 21 to swing in the first direction, causing the gripper unit 21 to clamp the lens 5; when the gripper adjusting member 23 moves away from the lens 5, it stops abutting against the gripper unit 21, thereby causing the gripper unit 21 to stop clamping the lens 5 and releasing the lens 5.

[0050] Reference Figure 2 and Figure 3As shown, the pressure adjusting assembly 3 includes a main shaft 31, a first adjusting pressure roller 32, a second adjusting pressure roller 33, and an elastic element 34. The main shaft 31 is movably connected to the gripper shaft 22 along the axial direction, allowing the gripper shaft 22 to move relative to the main shaft 31 along the axial direction, but the gripper shaft 22 cannot move relative to the main shaft 31 in the radial direction. Therefore, when the main shaft 31 moves in a non-axial direction, it can drive the gripper shaft 22 to move, thereby driving the lens 5 to move relative to the grinding area 11, and grinding the lens 5. The first adjusting pressure roller 32 is mounted on the gripper shaft 22, and the second adjusting pressure roller 33 is movably mounted on the main shaft 31 along the axial direction of the main shaft 31; the elastic element 34 is disposed between the first adjusting pressure roller 32 and the second adjusting pressure roller 33. By adjusting the position of the second adjusting pressure roller 33, the compression amount of the elastic element 34 can be adjusted, thereby adjusting the pressure applied by the elastic element 34 to the clamping assembly 2, and thus adjusting the pressure on the lens 5. By controlling the pressure on the lens 5, the grinding thickness of the lens 5 can be controlled. In this embodiment, the second adjusting pressure roller 33 can be connected to the main shaft 31 by a threaded connection, facilitating the adjustment of the position of the second adjusting pressure roller 33. It should be noted that in this embodiment, the elastic element 34 can be a spring; in other embodiments, other parts with elastic potential energy can also be used. In this embodiment, the two ends of the elastic element 34 abut against the first adjusting pressure roller 32 and the second adjusting pressure roller 33 respectively; in other embodiments, the elastic element 34 can also be connected to one of the first adjusting pressure roller 32 and the second adjusting pressure roller 33, or to both.

[0051] Reference Figure 1 As shown, the drive assembly 4 is mounted on the frame 1. The drive assembly 4 is connected to the spindle 31 and is used to drive the spindle 31 to move, thereby driving the clamping assembly 2 to move, thus realizing the polishing of the lens 5.

[0052] The lens polishing mechanism provided in this embodiment drives the gripper unit 21 to swing via the gripper adjustment component 23, pressing the lens 5 onto the polishing area 11, thus stably clamping lenses 5 of different sizes. By adjusting the position of the second adjusting pressure roller 33, the compression of the elastic element 34 can be adjusted, thereby adjusting the pressure applied to the lens 5 by the elastic element 34. By adjusting the pressure on the lens 5, the polishing thickness of the lens 5 can be controlled. The structure of this invention is applicable to lenses 5 of different sizes and can control the polishing thickness of the lens 5. On the one hand, the structure is simple, reducing the use of processing auxiliary fixtures and reducing costs; on the other hand, it reduces human error in polishing thickness control, shortens the overall processing and adjustment cycle of the lens 5, and controls costs.

[0053] Reference Figure 3 , Figure 4 and Figure 5As shown, the gripper adjustment component 23 includes a third adjusting pressure roller 231 and a pressure cylinder 232. The third adjusting pressure roller 231 is threadedly connected to the gripper shaft 22, facilitating the adjustment of its position. The pressure cylinder 232 is slidably fitted onto the gripper shaft 22 along its axial direction. The pressure cylinder 232 abuts against the third adjusting pressure roller 231, and a guide slope 233 is provided on the side of the pressure cylinder 232; this guide slope 233 is frustum-shaped, and its diameter gradually decreases as it approaches the lens 5. The end of the gripper unit 21 abuts against the guide slope 233, causing the pressure cylinder 232 to move toward the grinding area 11, thereby driving the gripper unit 21 to swing and clamp the lens 5. When the third adjusting pressure roller 231 moves toward the lens 5, it pushes the pressure cylinder 232 toward the grinding area 11. Since the gripper unit 21 abuts against the guide slope 233, the gripper unit 21 swings and clamps the lens 5.

[0054] Specifically, a spring ring 24 is connected between the gripper unit 21 and the gripper shaft 22. The spring ring 24 has elastic potential energy that drives the gripper unit 21 to swing in the direction of releasing the lens 5. When the third adjusting pressure roller 231 moves away from the lens 5, it loses its limiting position. Under the action of the spring ring 24, it can drive the gripper unit 21 to swing in a second direction, thereby quickly releasing the lens 5, where the first direction is opposite to the second direction. Furthermore, since the gripper unit 21 abuts against the guide slope 233 of the pressure cylinder 232, it can squeeze the pressure cylinder 232, causing the pressure cylinder 232 to abut towards the third adjusting pressure roller 231, and then return the pressure cylinder 232 to abut against the third adjusting pressure roller 231.

[0055] Reference Figure 4 As shown, the gripper unit 21 includes a first connecting rod 211, a second connecting rod 212, and a gripper rod 213; the gripper shaft 22 includes a shaft body 221 and a third connecting rod 222. The first connecting rod 211 is hinged to the gripper rod 213 and the third connecting rod 222 respectively, and the second connecting rod 212 is hinged to the gripper rod 213 and the third connecting rod 222 respectively, so that the first connecting rod 211, the second connecting rod 212, the gripper rod 213, and the third connecting rod 222 form a parallelogram shape; the third connecting rod 222 is connected to the shaft body 221. Since the third link 222 is connected to the shaft 221, the tilt angle of the third link 222 remains constant. Since the first link 211, the second link 212, the gripper bar 213 and the third link 222 form a parallelogram shape, during the process of the gripper unit 21 swinging to clamp and release the lens 5, the gripper bar 213 always remains parallel to the third link 222, so that the gripping end of the gripper bar 213 does not deflect, thereby ensuring reliable clamping of the lens 5 by the gripping end.

[0056] It should be noted that the first connecting rod 211 includes an extension section 214, which extends from the hinge point of the first connecting rod 211 and the third connecting rod 222 toward the pressure cylinder 232. A pulley 215 is rotatably connected to the end of the extension section 214, so that the pulley 215 abuts against the guide inclined surface 233, facilitating the movement of the first connecting rod 211 on the guide inclined surface 233. The spring ring 24 is connected between the extension section 214 and the gripper shaft 22.

[0057] Specifically, refer to Figure 6 As shown, the gripper bar 213 includes a first gripping surface 2131 and a second gripping surface 2132. The plane containing the first gripping surface 2131 intersects the plane containing the second gripping surface 2132; the first gripping surface 2131 is attached to the outer edge of the lens 5, and the second gripping surface 2132 is attached to the end of the lens 5. Since the gripper bar 213 remains parallel to the third connecting rod 222 during clamping or releasing, and its tilt angle does not change, the angle between the first gripping surface 2131 and the second gripping surface 2132 remains constant. When gripping lenses 5 of different sizes, it can always ensure that the first gripping surface 2131 is attached to the outer edge of the lens 5 and the second gripping surface 2132 is attached to the end of the lens 5, thus stably gripping lenses 5 of different sizes.

[0058] Specifically, a mounting groove is formed between the first clamping surface 2131 and the second clamping surface 2132, and an elastic pad 2133 is installed in the mounting groove. When clamping the lens 5, the elastic pad 2133 abuts against the corner of the lens 5 to eliminate clamping gaps, provide pre-pressure, and protect the corner of the lens 5.

[0059] Reference Figure 3 and Figure 4 As shown, the end of the main shaft 31 is provided with a shaft hole 311, which is open at one end and extends along the axial direction of the main shaft 31. A pin 312 is installed in the shaft hole 311, and the pin 312 extends along the radial direction of the main shaft 31. The end of the gripper shaft 22 is provided with a movable groove 223; the gripper shaft 22 is movably inserted into the shaft hole 311 along the axial direction, and the pin 312 is engaged in the movable groove 223. Through the cooperation of the pin 312 and the movable groove 223, when the main shaft 31 moves or rotates in the radial direction, it can drive the gripper shaft 22 to move accordingly; at the same time, the gripper shaft 22 can also move relative to the main shaft 31 along the axial direction.

[0060] Specifically, the movable groove 223 includes a groove opening and a groove body. The groove opening is located at the end of the gripper shaft 22, and the groove body extends from the groove opening to the other end of the gripper shaft 22, and the groove body penetrates the gripper shaft 22 in the radial direction. The groove body includes a first plane and a second plane opposite to each other, and the pin 312 is inserted into the groove body and abuts against the first plane and the second plane respectively.

[0061] Reference Figure 1 and Figure 8 As shown, the drive assembly 4 includes an internal gear 41, an external gear 42, and a drive rod 43. The internal gear 41 is mounted on the frame 1, the external gear 42 meshes with the internal gear 41, and the main shaft 31 is connected to the internal gear 41. Specifically, the main shaft 31 is inserted into the internal gear 41, and the internal gear 41 is connected to the main shaft 31 by a first screw 44. The drive rod 43 is rotatably mounted on the frame 1 and connected to the internal gear 41. The drive rod 43 includes a rotating shaft 431 and a drive connecting rod 432. The rotating shaft 431 is rotatably mounted on the frame 1 via a first bearing 434. The drive connecting rod 432 is connected to the rotating shaft 431 and extends radially along the rotating shaft 431. An annular ring 433 is connected to the end of the drive connecting rod 432. The annular ring 433 is internally connected to the internal gear 41 via a second bearing 435. When the drive shaft 431 rotates, the internal gear 41 revolves around the axis of the external gear 42. At the same time, due to the meshing of the internal gear 41 and the external gear 42, the internal gear 41 rotates around its own axis. This drives the main shaft 31 to revolve and rotate, thereby causing the lens 5 to rotate and revolve accordingly, resulting in a more uniform polishing effect.

[0062] Specifically, the frame 1 includes a bottom frame 12, a middle frame 13, and a top frame 14. The bottom frame 12 is connected to the middle frame 13 via a first column 15, and the top frame 14 is connected to the middle frame 13 via a second column 16. The grinding area 11 is disposed on the bottom frame 12, the external gear 42 is mounted on the middle frame 13 via a second screw 45, and the rotating shaft 431 is rotatably mounted on the top frame 14.

[0063] The first column 15 has a telescopic structure, allowing it to extend and retract along its axial direction, thus changing the distance between the middle frame 13 and the bottom frame 12. When only the lens 5 is clamped, the clamping assembly 2 can be moved along the axial direction to separate the gripper shaft 22 from the main shaft 31, allowing the clamping assembly 2 to be removed. At this time, the first column 15 extends to provide sufficient space for the clamping assembly 2 to move. After removing the clamping assembly 2, it is easier to adjust it to clamp the lens 5. After clamping the lens 5, the clamping assembly 2 can be reassembled onto the main shaft 31. After reassembly, the first column 15 is shortened, allowing the lens 5 to abut against the grinding area 11.

[0064] It should be noted that the telescopic structure of the first column 15 can be implemented in several ways. For example, it can be achieved by using two interlocking rods, which are fixed together by pins; or it can be achieved by using electric telescopic rods or hydraulic rods.

[0065] In this embodiment, the drive rod 43 is connected to a handle 46. By holding the handle 46, the clamping assembly 2 can be moved to polish the lens 5, eliminating the need for a power source and improving adaptability to the operating area. In other embodiments, a motor can be connected to the drive rod 43 for driving.

[0066] During the lens polishing process, by selecting a reasonable transmission ratio between the external gear 42 and the internal gear 41, the periodic overlap of polishing positions is reduced, thereby improving the uniformity of polishing and avoiding excessively large gear volumes. In this embodiment, the meshing transmission ratio between the external gear 42 and the internal gear 41 is A:B, where A is any value from 17, 19, 23, 29, to 31. That is, A is a prime number, so that the internal gear 41 needs to rotate A*B revolutions before the polishing positions overlap. For example, in this embodiment, the transmission ratio between the external gear 42 and the internal gear 41 is 23:10, so that the internal gear 41 rotates 230 revolutions before the polishing positions overlap.

[0067] Polishing process:

[0068] Clamp the lens 5, remove the clamping assembly 2, so that the lens 5 is located in and aligned within the multiple gripper units 21; rotate the third adjusting pressure wheel 231 toward the direction close to the lens 5, so that the gripper units 21 swing and clamp the lens 5.

[0069] Adjust the grinding pressure, load the clamping assembly 2 onto the spindle 31 so that the lens 5 abuts against the grinding area 11, rotate the second adjusting pressure roller 33 along the axis of the spindle 31 to adjust the compression of the elastic element 34 and adjust the pressure applied to the lens 5.

[0070] To polish lens 5, hold handle 46 to drive internal gear 41 to rotate around the axis of external gear 42. Since internal gear 41 meshes with external gear 42, internal gear 41 rotates around its own axis at the same time, thereby driving lens 5 to rotate and revolve, thus polishing lens 5.

[0071] Remove the lens 5, take off the clamping assembly 2, and rotate the third adjusting pressure wheel 231 in a direction away from the lens 5. After losing the pressure of the third adjusting pressure wheel 231, the gripper unit 21 is driven to swing in the opposite direction under the action of the spring ring 24, thereby releasing the lens 5.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
