Description

Technical Field

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

[0002] Spherical optical spectacle lenses are a common type of spectacle lenses, and their design is based on spherical geometry. The upper and lower surfaces of this type of lens are spherical, and the curvatures of the two spherical surfaces are different. They are suitable for correcting refractive errors such as myopia and hyperopia.

[0003] In order to ensure that the lens surface is smooth, transparent, without scratches or defects, and to improve the light transmittance and comfort of the lens, it is necessary to polish the two spherical surfaces of the lens during the production process. Currently, during the polishing operation, the lens is first fixed on a designated fixture, and the lens is pressed by a polishing plate used for polishing. The designated fixture drives the lens to rotate a whole circle, and the polishing plate moves back and forth left and right, so as to polish the lens.

[0004] The following problems exist in the current grinding process of eyeglass lenses: during polishing, the center of the polished surface of the lens needs to be located on the axis of the reciprocating swing of the polishing plate. Since the positions of the centers of the two spherical surfaces of the lens are different, when polishing the other spherical surface, it is necessary to replace another fixture. The process of replacing the fixture twice increases the error during the operation. Secondly, it takes more time and cost, which is not conducive to batch polishing operations.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1As shown, a polishing device for optical lenses comprises: a bottom plate 1, the bottom plate 1 is in a cross shape, two left-right symmetrical side plates 2 are fixedly arranged on the transverse section of the bottom plate 1, two sliding blocks 20 distributed up and down are slidably arranged on the side plates 2, a lifting plate 1 21 is fixedly arranged between the two sliding blocks 20 opposite to each other on the lower side, and the lifting plate 1 21 is driven to move up and down by external hydraulic pressure (not shown in the figure), a lifting plate 22 is fixedly arranged between the two sliding blocks 20 opposite to each other on the upper side, and a polishing unit 3 is arranged between the lifting plate 1 21 and the lifting plate 22.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the polishing unit 3 includes a rotating shaft 30, and a rotating shaft 30 with a vertical axis is installed on and rotated on the lifting plate 21, and the rotating shaft 30 is connected to an external motor 1 (not shown in the figure). A rubber suction cup 31 is fixedly provided on the upper end surface of the rotating shaft 30, and a swing plate 32 is rotatably provided on the front end surface of the lifting plate 22 through a driving shaft, and the driving shaft is connected to an external motor 2 (not shown in the figure). A swing rod 33 is slidably provided on the lower end surface of the swing plate 32 along its length direction, and a spring 34 extending along its length direction is fixedly provided between the swing rod 33 and the swing plate 32, and a polishing plate 35 is hinged on the lower end surface of the swing rod 33, and a driving group 36 is provided on the two side plates 2.

[0034] like Figure 1 , Figure 3 and Figure 8 As shown, a locking mechanism 4 is provided on the base plate 1, and the locking mechanism 4 includes a vertical plate 40. Two front-to-back symmetrical vertical plates 40 are fixedly provided on the longitudinal section of the base plate 1, and a rotating ring 400 is commonly provided above the two vertical plates 40. A plurality of sliding columns 401 uniformly distributed in the circumferential direction are provided in the rotating ring 400 for radial sliding. A pushing plate 402 is fixedly provided on the end surface of the sliding column 401 facing the center of the rotating ring 400, and a clamping block 403 is fixedly provided on the end surface of the pushing plate 402 facing the center of the rotating ring 400. A driving group 2 44 is provided on the lifting plate 21.

[0035] During operation, the staff holds the lens to be polished and moves the lens so that the lens is located in the circular area of ​​the rotating ring 400. Then, the external hydraulic cylinder works to make the lifting plate 21 drive the suction cup 31 to move upward, and the upper lifting plate 22 drives the polishing plate 35 to move downward through the driving group 1 36. During the above movement process, the driving group 2 44 drives the multiple push plates 402 in the rotating ring 400 to drive the corresponding clamping blocks 403 to approach each other, thereby completing the clamping and fixing of the circumferential surface of the lens. At the same time, the suction cup 31 presses the lower spherical surface of the lens and sucks the lens and the polishing plate 35 contacts the upper spherical surface of the lens. As the lifting plate 22 continues to move, the spring 1 34 is compressed, so the polishing plate 35 presses the upper spherical surface of the lens. Then, the external motor 1 drives the rotating shaft 30 to rotate, and the external motor 2 drives the driving shaft to swing back and forth. The polishing plate 35 polishes the rotating upper spherical surface of the lens during the reciprocating swing. After completing the polishing operation of the spherical surface of the lens, take out the rotating ring 400 and the lens and reverse the lens so that the unpolished spherical surface faces downward and the polished spherical surface faces downward. Then repeat the above operation for polishing, and finally complete the polishing operation of the lens.

[0036] like Figure 1 and Figure 2 As shown, the driving group 1 36 includes a gear 360, and the opposite back surfaces of the two side panels 2 are both provided with a gear 360 whose axis extends from left to right through a connecting shaft rotation, and a rack 361 meshing with the corresponding gear 360 is fixedly provided on the sliding block 20, and the racks 361 corresponding to the two sliding blocks 20 opposite to each other up and down are front-to-back symmetrical about the axis of the corresponding gear 360.

[0037] During operation, the external hydraulic cylinder works to move the lifting plate 21 upward, and the lifting plate 21 drives the corresponding two sliding blocks 20 to move upward synchronously. The sliding block 20 drives the rack 361 thereon to move upward and engages with the gear 360 at the same time. Through the engagement between the gear 360 and the other rack 361, the upper sliding block 20 drives the lifting plate 22 downward, and the lifting plate 22 drives the swing plate 32 and the polishing plate 35 thereon to move downward synchronously. The lower lifting plate 21 drives the suction cup 31 upward through the rotating shaft 30. Secondly, through the above process, the pushing plate 402 and the clamping block 403 clamp the lens. After completing the clamping operation, the suction cup 31 continues to move upward and the lifting plate 22 continues to move downward. Finally, the suction cup 31 presses the lower end surface of the lens and sucks the lens. The polishing plate 35 stops moving after contacting the upper spherical surface of the lens. The lifting plate 22 continues to move downward, so that the spring 1 34 is compressed. The elastic force generated by the compression of the spring 1 34 causes the upper end surface of the polishing plate 35 to press tightly against the upper spherical surface of the lens.

[0038] like Figure 1 and Figure 7As shown, the locking mechanism 4 also includes a locking group 41 arranged on the swing plate 32 and the front vertical plate 40, and the locking group 41 includes a fixing rod 1 410, and the front end surfaces of the swing plate 32 and the front end surfaces of the front vertical plate 40 are fixedly provided with a fixing rod 1 410 with an axis extending from the back to the front, and the upper end surface of the polishing plate 35 is fixedly provided with two fixing rods 2 411 distributed from the front to the back and with an axis extending from the back to the front through a connecting block, and a U-shaped avoidance member 412 is fixedly provided between the two fixing rods 2 411, and a locking plate 413 is slidably sleeved on the front and rear sides of the front fixing rod 2 411, and a sleeve hole is opened through the locking plate 413.

[0039] It should be noted that the two spherical surfaces of the lens have different diameters. Figure 1 At this time, the convex surface of the lens faces upward and the concave surface faces downward, and the convex surface is polished. When the lens is clamped and fixed and the polishing plate 35 is pressed against the convex surface of the lens, the staff moves the locking plate 413 so that the sleeve hole on the locking plate 413 is stuck on the fixing rod 1 410 corresponding to the vertical plate 40, and the axis position of the fixing rod 1 410 is colinear with the axis position of the horizontal vertical section of the convex surface of the lens. Therefore, in the subsequent process of the swing plate 32 driving the polishing plate 35 to swing back and forth, through the locking cooperation between the locking plate 413 and the lower side fixing rod 1 410 and the fixing rod 2 411, the polishing plate 35 is centered on the axis of the horizontal vertical section of the convex surface of the lens and performs a reciprocating swing polishing operation.

[0040] After the locking plate 413 is moved forward to unlock, the rotating ring 400 and the fixed lens are taken out and turned over so that the concave surface of the lens faces upward, and then the rotating ring 400 is placed on the vertical plate 40. At this time, the axis of the transverse vertical section of the concave surface of the lens is collinear with the axis of the drive shaft, and the above locking process is repeated so that the locking plate 413 cooperates with the fixing rod 410 located on the front end surface of the swing plate 32 to lock the swing plate 32 and the polishing plate 35, so that in the process of the polishing plate 35 swinging back and forth, the axis of the swing trajectory of the polishing plate 35 is collinear with the axis of the drive shaft and the axis of the transverse vertical section of the concave surface of the lens. In summary, the locking plate 413 is used to adapt to the polishing process of the two spherical surfaces of the lens, and the stability of the polishing process is improved by locking, while ensuring the accuracy of the polishing of the spherical surface of the lens to avoid the problem of over-polishing or insufficient polishing effect.

[0041] like Figure 1 , Figure 4 and Figure 5As shown, the locking mechanism 4 also includes a plug-in group 42 arranged on the rotating ring 400, and the plug-in group 42 includes a connecting ring 420. The outer ring surface of the rotating ring 400 is rotatably provided with two connecting rings 420 distributed up and down, and the opposite sides of the two connecting rings 420 are fixedly provided with plate groups corresponding to the vertical plates 40 one by one, and the two plate groups on the same connecting ring 420 are symmetrical front and back, and the two plate groups opposite to each other on different connecting rings 420 are symmetrical up and down. The plate group on the connecting ring 420 includes two left-right symmetrical card plates 421. The card plate 421 on the left side of the upper connecting ring 420 is used as an example for explanation. The left card plate 421 is a rectangular segment and an upright right-angled trapezoidal segment from bottom to top. The inclined surfaces of the right-angled trapezoidal segments of the two card plates 421 in the same plate group are opposite to each other, and the rectangular segment of the card plate 421 is made of elastic material. The upper end surface of the vertical plate 40 is provided with a cross-shaped card groove 422.

[0042] Initially, the rotating ring 400 is manually moved downward, and the card plate 421 on the lower side of the rotating ring 400 is inserted into the corresponding card slot 422. During the plugging process, the elasticity of the rectangular section of the card plate 421 enables the right-angled trapezoidal section of the card plate 421 to be inserted into the corresponding card slot 422, and the right-angled trapezoidal sections on the two card plates 421 in the same card slot 422 cooperate with the card slot 422 to complete the locking of the rotating ring 400 and the connecting ring 420, which is convenient for the subsequent installation of the lens and the polishing process. Later, when the lens needs to be turned over, the right-angled trapezoidal section of the card plate 421 is manually pressed so that The right-angled trapezoidal section of the clamping plate 421 is retracted into the clamping slot 422, and the connecting ring 420, the rotating ring 400 and the lens are taken out at the same time. Then, the rotating ring 400 is turned over, and the above process is repeated, so that the clamping plate 421 on the other connecting ring 420 is re-inserted into the corresponding clamping slot 422, completing the locking and plugging process of the rotating ring 400 and the lens. Through the above process, the stability of the polished surface of the lens is improved. Secondly, there is no need to release the clamping fixation of the lens during the flipping process, which avoids the problem of error caused by losing the reference or needing to re-clamp the clamping fixation due to releasing the clamping fixation of the lens.

[0043] like Figure 1 , Figure 6 and Figure 7As shown, the locking mechanism 4 also includes a spring 2 43, and a spring 2 43 mounted on the sliding column 401 is fixedly arranged between the pushing plate 402 and the rotating ring 400. The driving group 2 44 includes an inclined plate 440, and the end face of the sliding column 401 away from the pushing plate 402 is hingedly provided with an inclined plate 440. The right inclined plate 440 is taken as an example for explanation. The right inclined plate 440 is inclined upward from left to right, and two left-right symmetrical pushing rods 441 with vertical axes slide up and down on the lifting plate 21. The upper end faces of the two pushing rods 441 are fixedly provided with a matching ring plate 442 with a right side transverse section inclined upward from left to right. A pushing frame 443 located between the matching ring plate 442 and the lifting plate 21 is fixedly sleeved on the pushing rod 441, and a spring 3 444 is fixedly arranged between the pushing frame 443 and the lifting plate 21.

[0044] like Figure 6 As shown, a plurality of grooves evenly distributed along the longitudinal length direction of the inclined plate 440 are fixedly provided on the end surface of the inclined plate 440 facing the matching ring plate 442, and a rotating roller 45 is rotatably provided in the groove.

[0045] like Figure 4 and Figure 6 As shown, a self-locking group 46 is commonly provided between the rotating ring 400 and all the sliding columns 401, and the self-locking group 46 includes a self-locking hole 460. The sliding column 401 is provided with a self-locking hole 460 extending therethrough, and a locking column 461 corresponding to the sliding column 401 and having a vertical axis is slidably provided on the lower end surface of the rotating ring 400, and a fixing ring 462 is commonly fixedly provided on the lower end surfaces of all the locking columns 461, and a spring 463 is commonly fixedly provided between the fixing ring 462 and the rotating ring 400.

[0046] When the lens is clamped and fixed, during the upward movement of the lifting plate 21, the lifting plate 21 drives the spring three 444, the pushing frame 443 and the pushing rod 441 to move upward synchronously. When the pushing rod 441 drives the matching ring plate 442 to move up until the matching ring plate 442 contacts the inclined plate 440, the pushing rod 441 stops moving. As the lifting plate 21 continues to move, the spring three 444 is deformed. The elastic force generated by the deformation of the spring three 444 causes the pushing frame 443 to drive the pushing rod 441 and the matching ring plate 442 to continue to move upward. Through the cooperation between the inner ring surface of the matching ring plate 442 and the inclined plate 440, the inclined plate 440 drives the sliding column 401 to move in the direction away from the matching ring plate 442. The sliding column 401 drives the pushing plate 402 and the clamping block 403 to approach the lens and finally press the lens. The spring two 43 is stretched. In the subsequent resetting process, the elastic force generated by the stretching and deformation of the spring two 43 causes the clamping block 403 and the pushing block to reset.

[0047] In the initial state, the locking column 461 is against the corresponding sliding column 401, and the spring four 463 is in a stretched state. When the sliding column 401 continues to move until all the clamping blocks 403 jointly clamp and fix the lens, the self-locking hole 460 is opposite to the locking column 461. The elastic force generated by the stretched deformation of the spring four 463 causes the fixing ring 462 to drive all the locking columns 461 to move up and insert into the corresponding self-locking hole 460. The locking of the sliding column 401, the pushing plate 402 and the clamping block 403 is completed through the cooperation between the locking column 461 and the corresponding self-locking hole 460, so that after the lens is subsequently flipped, the polishing reference of the two spherical surfaces of the lens can still be determined based on the rotating ring 400.

[0048] After polishing of the two spherical surfaces of the lens is completed, the card plate 421 is pressed to remove the rotating ring 400, and then the fixed ring 462 is manually pulled to make the fixed ring 462 move away from the rotating ring 400. The fixed ring 462 drives the locking column 461 to withdraw from the self-locking hole 460, and the elastic force generated by the deformation of the spring 2 43 resets the clamping block 403, and the polished lens is taken out.

[0049] It should be noted that in the process of the rotating shaft 30 driving the lens to rotate a whole circle, the clamping block 403, the pushing plate 402 and the inclined plate 440 all rotate synchronously. The friction between the inclined plate 440 and the matching ring plate 442 is reduced by the contact between the rotating roller 45 and the matching ring plate 442, thereby avoiding wear caused by contact with the matching ring plate 442 during the rotation of the inclined plate 440. Secondly, the matching ring plate 442 supports the corresponding inclined plate 440 upward, thereby also supporting the rotating ring 400 and the lens, ensuring the horizontality of the rotating ring 400 and the lens, and improving the stability during the polishing process. After the lens is flipped over, the inclined plate 440 adapts to the inner ring surface of the matching ring plate 442, so the matching ring plate 442 still supports the rotating ring 400 and the lens after rising.

[0050] like Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the locking mechanism 4 also includes a clamping group 47, and all the pushing plates 402 are commonly provided with a clamping group 47, and the clamping group 47 includes a hinged plate 470, and the end surface of the pushing plate 402 facing the center of the rotating ring 400 is hinged with a hinged plate 470, and a spring 471 is commonly fixedly provided between the hinged plate 470 and the pushing plate 402, and a fitting plate 472 is fixedly provided on the hinged plate 470.

[0051] like Figure 1 , Figure 3 , Figure 4 and Figure 8As shown, the end surface of the push plate 402 facing the center of the rotating ring 400 is hinged with a hinge plate 2 473 located below the hinge plate 1 470 , a spring 6 474 is fixedly provided between the hinge plate 2 473 and the push plate 402 , and a fitting plate 2 475 is fixedly provided on the hinge plate 2 473 .

[0052] like Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the clamping group 47 also includes a rectangular plate 476, and a rectangular plate 476 is fixedly provided on the rotating shaft 30 through a connecting ring, and is located between the lifting plate 21 and the pushing plate 402 and corresponds to the pushing plate 402 one by one. A guide column 477 is fixedly provided on the upper end surface of the rectangular plate 476, and a guide groove 478 corresponding to the guide column 477 is provided on the hinge plate 1 470 and the hinge plate 2 473, and the upper end of the guide column 477 and the end of the guide groove 478 are chamfered, and the guide groove 478 is a waist-shaped groove, and its length is greater than the diameter of the guide column 477 and its width is equal to the diameter of the guide column 477.

[0053] It should be noted that, in the initial state, the bonding plate 1 472 and the bonding plate 2 475 on the same pushing plate 402 are both away from the middle horizontal section of the pushing plate 402. When the bonding plate 1 472 is in a horizontal state, the bonding plate 1 472 fits tightly against the convex surface of the lens. When the bonding plate 2 475 is in a horizontal state, the bonding plate 2 475 fits tightly against the concave surface of the lens.

[0054] During operation, during the upward movement of the lifting plate 21, the lens is first clamped and fixed by the driving group 2 44, so that the inner concave surface of the lens faces downward. As the lifting plate 21 continues to move upward, the lifting plate 21 drives all the rectangular plates 476 to move upward synchronously through the rotating shaft 30. The rectangular plates 476 contact the horizontal section of the hinge plate 2 473 and push the hinge plate 2 473 to drive the bonding plate 2 475 to deflect. The spring 6 474 is stretched, and finally the bonding plate 2 475 is horizontal and pressed against the lens. The inner concave surface of the lifting plate 21 stops moving up. Secondly, in the above process, the guide column 477 on the rectangular plate 476 is gradually inserted into the guide groove 478 on the hinge plate 473. Therefore, when the bonding plate 475 is horizontal, the guide column 477 is completely inserted into the above guide groove 478, locking the hinge plate 473 and driving the push plate 402 and the clamping block 403 to rotate through the rectangular plate 476, thereby avoiding circumferential movement between the lens and the clamping block 403 and affecting the polishing.

[0055] The operation of the external hydraulic cylinder causes the lifting plate 21 to move downward, releasing the fit between the rectangular plate 476 and the hinged plate 473. Therefore, the elastic force generated by the stretching of the spring 6 474 causes the bonding plate 2 475 to reset. Then, the lens is flipped over, and the hinged plate 470 and the bonding plate 472 are flipped to the lower side of the lens. During the process of the lifting plate 21 driving the rectangular plate 476 to move upward, the rectangular plate 476 contacts the bonding plate 472 and pushes the bonding plate 472 to gradually rotate to a horizontal state. The spring 5 471 is stretched. Secondly, during the rotation of the bonding plate 472, the guide column 477 is gradually inserted into the guide groove 478 on the hinged plate 470, and then the above operation is repeated.

[0056] In summary, during the polishing process of the two spherical surfaces of the lens, the lens is supported by the bonding plate 1 472 or the bonding plate 2 475 being close to the lens, so as to avoid uneven force on the lens during the polishing process and causing deviation, which affects the polishing effect. Secondly, the elastic force generated by the deformation of the spring 5 471 and the spring 6 474 makes it easy to keep the bonding plate 1 472 or the bonding plate 2 475 away from the lens during the subsequent resetting process, that is, in the initial state, the bonding plate 1 472 and the bonding plate 2 475 are away from the lens, so as to avoid interference between the bonding plate 1 472, the bonding plate 2 475 and the polishing plate 35 during the rotational polishing of the lens. The avoidance member 412 can avoid the bonding plate 1 472 or the bonding plate 2 475 during the rotational polishing process.
