Description

Technical Field

[0001] The present invention relates to the field of optical lens processing, in particular to a polishing device for optical lens processing. Background Art

[0002] Polishing of optical lenses is one of the key processes in the field of precision optical manufacturing. At present, common optical lens polishing devices usually include an operating table, a reciprocating mechanism, a grinding head and a rotating seat for fixing the optical lens. During operation, the reciprocating motion of the reciprocating mechanism drives the grinding head to polish the optical lens on the rotating seat. This type of equipment drives the lens to rotate by the rotation of the rotating seat, and combines the reciprocating motion of the grinding head to achieve uniform grinding of the lens surface.

[0003] However, there are still some problems with the existing polishing devices. First, the movement mode of the polishing head is single. It usually does not rotate actively and only relies on the rotation of the optical lens for friction polishing. This passive polishing method leads to low polishing efficiency. Secondly, when the rotating seat drives the optical lens to rotate, the linear speed of the lens edge is significantly higher than that of the center area, resulting in the polishing speed of the part far from the axis being too fast, while the polishing speed of the part close to the axis is insufficient, which ultimately causes uneven polishing of the lens surface and affects the consistency of optical performance.

[0004] In addition, the material changing process of existing equipment is cumbersome, and the operator needs to manually lift the grinding head to complete the removal and installation of the lens. This process is not only time-consuming, but also prone to damage to the lens or equipment due to misoperation, which seriously restricts the further improvement of processing efficiency. Therefore, there is an urgent need for a new type of optical lens processing device that can achieve efficient and uniform polishing and simplify the material changing process.

[0030] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0031] See Figure 1 and Figure 2 A polishing device for optical lens processing includes an operating table 1, a reciprocating machine 2 and a rotating seat 5. A polishing mechanism 3 for efficiently polishing the optical lens is provided on the front side of the reciprocating machine 2, and a material changing mechanism 4 for conveniently replacing the optical lens is provided on the operating table 1.

[0032] When the optical lens needs to be polished, the optical lens is first moved to the position of the grinding mechanism 3 through the material changing mechanism 4, and then the rotating seat 5 drives the optical lens located at the grinding mechanism 3 to rotate, and the optical lens is ground and polished through the grinding mechanism 3 and the reciprocating machine 2. During the polishing process, the operator manually places the optical lens to be polished on the material changing mechanism 4 and removes the polished optical lens from the material changing mechanism 4.

[0033] See Figure 1 、 Figure 2 and Figure 3 The grinding mechanism 3 includes a frame 31 rotatably arranged on the front side of the reciprocating machine 2, a grinding head 32 is detachably arranged on the frame 31, and a grinding ring 34 is arranged through a pushing component 33, and the grinding ring 34 is located outside the coaxial line of the grinding head 32.

[0034] See Figure 1 、 Figure 2 and Figure 6The material changing mechanism 4 includes a conversion table 41 rotatably arranged on the front side of the operating table 1. A number of equally spaced placement seats 42 for fixing optical lenses are rotatably arranged on the conversion table 41 along its circumference. The conversion table 41 is manually rotated to switch the optical head lens for polishing through the placement seat 42.

[0035] See Figure 2 、 Figure 6 and Figure 7 The lower part of the conversion platform 41 is a rod-shaped structure. The outer side of the shaft structure of the conversion platform 41 is provided with locking grooves corresponding to the placement seats 42 at equal intervals along its circumference. A T-shaped locking piece 411 is provided on the conversion platform 41 for sliding left and right and inserted into the locking groove. A coil spring is provided between the T-shaped locking piece 411 and the conversion platform 41.

[0036] See Figure 6 and Figure 7 A rectangular groove is provided on the outer surface of the placement seat 42, and a plurality of rectangular plug-ins 412 are arranged on the conversion table 41 at equal intervals along its circumference and radially slide along the conversion table 41. The rectangular plug-ins 412 correspond to the placement seats 42 one by one, and a tension spring 2 is provided between the rectangular plug-in 412 and the placement seat 42. A pushing plate frame 413 for pushing the rectangular plug-in 412 backward is fixedly installed on the upper side of the conversion table 41 and at the rear of the conversion table 41.

[0037] See Figure 6 An arc-shaped groove is provided at the upper end of the rotating seat 5 , and an arc-shaped plate 421 for inserting into the inner part of the arc-shaped groove is fixedly installed on the lower side of the placement seat 42 .

[0038] In the initial state, the placement seats 42 on the conversion table 41 are all equipped with optical lenses in a detachable manner, and the placement seat 42 at the rear and the optical lens thereon are both located at the lower position of the grinding head 32, the rotating seat 5 is coaxially arranged with the rear placement seat 42, and at the same time, the rectangular plug-in 412 corresponding to the position of the rear placement seat 42 moves to the position of the pushing plate frame 413, so that the pushing plate frame 413 pushes the rectangular plug-in 412 backward to exit the rectangular groove of the rear placement seat 42, so that the rear placement seat 42 can rotate freely on the conversion table 41, and the remaining rectangular plug-ins 412 are all inserted into the corresponding rectangular grooves, so that the remaining placement seats 42 are locked together with the conversion table 41.

[0039] It should be noted that if Figure 2 and Figure 7As shown, the pushing plate frame 413 is composed of an L-shaped support rod and a wedge-shaped plate fixedly installed on the front end of the lower side of the vertical section of the support rod. A protruding rod is fixedly installed on the rectangular plug-in 412. When the rectangular plug-in 412 moves to the position of the pushing plate frame 413, the wedge-shaped plate on the pushing plate frame 413 pushes the protruding rod at the corresponding position away from the conversion table 41 through the inclined surface thereon, so that the rectangular plug-in 412 located at the pushing plate frame 413 exits the rectangular groove at the corresponding position.

[0040] At this time, the arc-shaped plate 421 on the rear placement seat 42 is inserted into the arc-shaped groove of the rotating seat 5, so that the rotating seat 5 can drive the rear placement seat 42 to rotate synchronously through the arc-shaped plate 421, and the T-shaped lock 411 is inserted into the locking groove at the corresponding position under the push of the coil spring's own elastic force, thereby locking the conversion table 41 and the operating table 1 together, preventing the conversion table 41 from rotating without manual operation, and ensuring that the rear placement seat 42 is always arranged coaxially with the rotating seat 5.

[0041] See Figure 2 and Figure 3 The frame 31 includes a shaft member 311 rotatably connected to the front side of the reciprocating machine 2, and a connecting shaft 312 is rotatably provided on the front side of the shaft member 311. The lower side of the connecting shaft 312 is fixedly connected to the grinding head 32 by threaded locking. A support platform 313 is fixedly installed on the upper side of the shaft member 311, and a synchronous motor 314 is fixedly installed on the upper side of the support platform 313. The output shaft of the synchronous motor 314 is fixedly connected to the connecting shaft 312.

[0042] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A ring frame 315 is fixedly installed on the lower side of the shaft member 311, and the pushing assembly 33 includes a swivel ring 331 rotatably arranged inside the ring frame 315. The lower side of the swivel ring 331 is movably connected to the grinding ring 34 through a guide column. During grinding, the reciprocating machine 2 drives the grinding head 32 and the grinding ring 34 to move back and forth on the optical lens through the frame 31, and at the same time rotates the grinding head 32 and the grinding ring 34 to grind. The pushing assembly 33 automatically adjusts the grinding force according to the resistance between the grinding ring 34 and the outer ring position of the optical lens.

[0043] See Figure 2 and Figure 3 An outer gear 332 is fixedly mounted on the inner side of the rotating ring 331 , an inner gear 333 is fixedly mounted on the outer side of the grinding head 32 , and a planetary gear 334 is rotatably mounted on the rear side of the ring frame 315 and meshes between the outer gear 332 and the inner gear 333 .

[0044] When the optical lens to be polished is arranged coaxially with the rotating seat 5, the synchronous motor 314 is started to drive the connecting shaft 312 to rotate, and the connecting shaft 312 drives the grinding head 32 to rotate, and the rotating seat 5 is rotated at the same time, so that the rotating seat 5 drives the optical lens to rotate in the opposite direction relative to the grinding head 32 through the placement seat 42, so that the grinding head 32 grinds the central area of ​​the optical lens.

[0045] See Figure 3 and Figure 4 A number of wedge blocks 335 are fixedly installed on the upper side of the grinding ring 34 along its circumference at equal intervals, and trapezoidal grooves corresponding to the wedge blocks 335 are arranged at equal intervals along the circumference of the lower side of the rotating ring 331. The trapezoidal grooves are used to push the wedge blocks 335 downward, and a tension spring is provided between the trapezoidal grooves and the corresponding wedge blocks 335.

[0046] When the grinding head 32 starts to rotate, the grinding head 32 drives the internal gear 333 to rotate, and the internal gear 333 drives the outer gear 332 to rotate in the opposite direction through the planetary gear 334. The outer gear 332 drives the rotating ring 331 to rotate, and the rotating ring 331 drives the grinding ring 34 to rotate by pushing the wedge block 335 through the trapezoidal groove thereon, so that the grinding ring 34 and the optical lens rotate in the same direction but at different speeds, and then the relative speed between the grinding ring 34 and the edge area of ​​the optical lens is close to the relative speed between the grinding head 32 and the center area of ​​the optical lens, which effectively eliminates the problem of uneven polishing caused by the difference in the linear speed of the lens rotation.

[0047] When the grinding ring 34 starts to grind the edge area of ​​the rough-surfaced optical lens, the rotational resistance of the grinding ring 34 on the optical lens is relatively large, so that the rotation of the grinding ring 34 is slow relative to the rotating ring 331, and then the rotating ring 331 pushes the grinding ring 34 downward through the cooperation between the trapezoidal groove thereon and the inclined surface of the wedge block 335, so that when the grinding ring 34 is grinding the rough-surfaced optical lens, the contact force between the grinding ring 34 and the optical lens is increased, thereby accelerating the grinding efficiency.

[0048] In addition, when the grinding ring 34 gradually grinds the edge area of ​​the optical lens smooth, the rotational resistance of the optical lens to the grinding ring 34 gradually decreases, so that the tension spring 1 gradually pulls the wedge block 335 to reset through its own elastic force, thereby gradually reducing the squeezing force of the grinding ring 34 on the optical lens, and then dynamically adjusts the grinding force according to the grinding degree of the optical lens, further increasing the polishing efficiency.

[0049] When the grinding head 32 and the grinding ring 34 start to grind the optical lens, the reciprocating machine 2 swings the frame 31 back and forth, and the frame 31 drives the grinding head 32 and the grinding ring 34 to move back and forth along the upper side grinding surface of the optical lens, thereby ensuring the consistency of the lens surface grinding and the stability of the optical performance.

[0050] It should be noted that the reciprocating machine 2 adopts a reciprocating structure commonly found on the market with the freedom of up and down swinging and left and right swinging, and when the reciprocating machine 2 moves the grinding head 32 and the grinding ring 34 downward until they are in contact with the top of the optical lens, the reciprocating machine 2 can be locked by a locking part, thereby preventing the reciprocating machine 2 from moving upward, so that the reciprocating machine 2 can drive the grinding head 32 and the grinding ring 34 to always be in contact with the upper side of the optical lens through gravity, and at the same time ensure that when the grinding ring 34 moves downward relative to the rotating ring 331, the rotating ring 331 is blocked by the reciprocating machine 2 and cannot move upward, thereby causing the grinding ring 34 to increase the pressure on the optical lens.

[0051] The locking member in this embodiment is a pin structure, which is inserted into the hinge position of the reciprocating machine 2 to block the upward rotation of the reciprocating machine 2.

[0052] See Figure 2 and Figure 6 A lifting plate 414 with an arc structure is fixedly installed on the upper side of the conversion table 41. The lifting plate 414 has a downwardly protruding bending structure corresponding to the position of the placement seat 42. The lifting plate 414 pushes the reciprocating machine 2 upward through the bending structure thereon.

[0053] After the optical lens is polished, stop rotating the rotating seat 5 so that when the rotating seat 5 stops, the axis of the arc groove on the rotating seat 5 coincides with the axis of the conversion platform 41. The arc groove on the rotating seat 5 drives the rear placement seat 42 to stop synchronously through the arc plate 421, so that the rectangular groove on the rear placement seat 42 corresponds to the position of the rectangular plug-in 412 at the corresponding position.

[0054] It should be noted that a servo motor that drives the rotating seat 5 is fixedly installed inside the operating table 1. The servo motor is not shown in the figure. The servo motor monitors and controls the rotating seat 5 through its own precise closed-loop rotation angle, so that the rotating seat 5 can stop accurately at the initial angle position when it stops, so that the axis of the arc groove on the rotating seat 5 coincides with the axis of the conversion table 41, and when the conversion table 41 drives the arc plate 421 to move out of the rectangular groove through the placement seat 42, the angle of the rotating seat 5 itself is not changed by friction.

[0055] The operator then moves the T-shaped lock 411 to the right until it exits the locking groove, and then rotates the manual rotation conversion table 41. As the conversion table 41 starts to rotate, the conversion table 41 drives the optical lens thereon to rotate synchronously through the placement seat 42, and at the same time removes the external force on the T-shaped lock 411, so that the T-shaped lock 411 is pushed against the outer surface of the rod-shaped structure of the conversion table 41 by the elastic force of the coil spring itself.

[0056] Then the operator unlocks the up and down swing lock of the reciprocating machine 2, and the conversion table 41 drives the lifting plate 414 on it to rotate synchronously, so that the lifting plate 414 pushes the reciprocating machine 2 upward, and the reciprocating machine 2 drives the grinding head 32 and the grinding ring 34 no longer in contact with the polished optical lens. Then the conversion table 41 drives the rectangular plug-in 412 at the rear to move to the side of the pushing plate frame 413, so that the tension spring 2 pulls the rectangular plug-in 412 through its own elastic force and inserts it into the rectangular groove at the corresponding position, thereby locking the placement seat 42 and the conversion table 41 together to prevent the placement seat 42 from rotating without manual operation.

[0057] Then it continues to rotate, so that the conversion table 41 drives the new optical lens to be polished to the rear through the placement seat 42. At this time, the conversion table 41 drives the bending structure of the lifting plate 414 on it to move to the position of the reciprocating machine 2 again. Under the action of gravity, the reciprocating machine 2 drives the grinding head 32 and the grinding ring 34 to rest on the optical lens to be processed for polishing. At the same time, the arc plate 421 on the placement seat 42 is inserted into the interior of the arc groove, pushing the plate frame 413 to push the rectangular plug-in 412 at the corresponding position out of the rectangular groove, and the T-shaped lock 411 is inserted into the locking groove at the corresponding position under the push of the coil spring's own elastic force.

[0058] Then the operator locks the up and down swing of the reciprocating machine 2 again, starts the private service motor to drive the optical lens to rotate, removes the polished optical lens from the placement seat 42, and then fixes the new optical lens to be polished on the placement seat 42.

[0059] It should be noted that the placement seat 42 is connected to the optical lens by means of conventional negative pressure adsorption or fixture fixation.

[0060] See Figures 1 to 7 When polishing the optical lens, the present invention also includes the following steps: the first step is to start the synchronous motor 314 to drive the grinding head 32 and the grinding ring 34 to rotate, the reciprocating machine 2 swings the grinding head 32 and the grinding ring 34 back and forth, and at the same time rotates the rotating seat 5, so that the grinding head 32 and the grinding ring 34 respectively evenly grind the center area and the edge area of ​​the optical lens.

[0061] In the second step, when the grinding ring 34 gradually grinds the edge area of ​​the optical lens smooth, the tension spring 1 gradually pulls the wedge 335 back to its original position through its own elastic force, thereby gradually reducing the squeezing force of the grinding ring 34 on the optical lens, and then dynamically adjusting the grinding force according to the grinding degree of the optical lens.

[0062] In the third step, after the optical lens is polished, the rotating seat 5 is stopped, and the operator moves the T-shaped lock 411 to the right until it exits the locking groove, and then rotates the manual rotation conversion table 41 to move the new optical lens to be polished to the position of the grinding head 32 and the grinding ring 34.

[0063] In the fourth step, the operator then locks the up and down swing of the reciprocating machine 2 again, starts the private motor to drive the optical lens to rotate, removes the polished optical lens from the placement seat 42, and then fixes the new optical lens to be polished on the placement seat 42.

[0064] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
