Description

Technical Field

[0001] The invention belongs to the field of optical lens processing, and in particular relates to an optical lens processing turntable. Background Art

[0002] In the field of optical lens manufacturing, a classic polishing process widely used in the industry is the hemispherical mold fixation method based on asphalt bonding. The process proceeds as follows: The hemispherical mold holding the lenses is heated to above the asphalt's softening point. Simultaneously, molten thermoplastic optical asphalt is poured onto the backside (non-working surface) of multiple optical lenses to be polished. The asphalt-coated lenses are quickly and precisely fitted onto the pre-determined positions on the preheated mold's spherical surface. The asphalt's fluidity and adhesion, combined with the heat of the mold surface, ensure initial positioning of the lenses. Rapid cooling (e.g., by pouring cold water) causes the asphalt to quickly solidify and harden between the mold and the lenses, forming a strong bond that rigidly secures the lenses to the mold's spherical surface. A precisely shaped grinding / polishing mask (typically with an embedded polishing pad or cloth) covers the entire surface of the hemispherical mold holding the lenses. The entire mold assembly (including the lenses affixed thereto) is rotated, while a polishing fluid is supplied. Under the influence of centrifugal force and friction, the lens's surface is constantly and evenly in contact with the inner wall of the rotating polishing hood, achieving a precise polish. After polishing, the entire mold assembly is reheated to above the asphalt's softening point, and the lenses are carefully removed one by one. Afterwards, any residual asphalt on the lens surface and any solidified asphalt on the mold's spherical surface must be thoroughly and meticulously cleaned to avoid contamination or damage to the optical surface.

[0003] However, this processing and fixing method has the following defects: 1. Each processing cycle is mandatory to include multiple time-consuming steps of heating-bonding-cooling-polishing-reheating-demolding-cleaning. The heating and cooling processes require precise temperature control and are time-consuming, which seriously limits the processing cycle and capacity improvement; 2. Cleaning the asphalt residue after the lens is demolded is an indispensable link. This process not only requires the use of specific solvents, but also requires extremely careful operation to avoid damaging the polished optical surface or introducing new contaminants. It is time-consuming and labor-intensive and increases the cost of waste liquid treatment; 3. Cleaning the mold itself is also time-consuming and labor-intensive. Each bonding requires a certain amount of optical-grade asphalt, and the cleaning process inevitably causes some asphalt to be unable to be recycled, increasing material costs; 4. If the traditional rigid mechanical fixing method is used, the pressure of the fixture will be concentrated at the contact point, which may cause the lens to be damaged due to excessive stress, and the stress will be released after the fixture is released, resulting in irreversible precision errors on the lens surface.

[0004] In summary, an optical lens processing turntable is urgently needed to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 -Attached Figure 11 This application is described in further detail.

[0032] Please refer to Figure 1 and Figure 2 An optical lens processing turntable includes a processing table 1, a processing groove 2 formed on the processing table 1, a base 3 disposed at the bottom of the processing groove 2, and two symmetrical turntable assemblies 4 disposed on the base 3. A drive assembly 1 5 is disposed between the two turntable assemblies 4 and the base 3. A polishing mechanism 6 is disposed on the turntable assembly 4. A lens 13 is directly fixed by the turntable assembly 4, and then the lens 13 is driven and controlled to rotate by the drive assembly 1 5, and the lens 13 is polished in conjunction with the polishing mechanism 6.

[0033] See Figure 2 and Figure 3 In order to replace the traditional asphalt to fix the lens 13 and avoid the problem of stress concentration and damage to the lens 13 caused by the traditional mechanical fixing method, the turntable assembly 4 includes a semicircular support cover 41, and the support cover 41 is connected to the base 3 through a support pipe 42. The outer arc surface of the support cover 41 is covered with a rubber sleeve 43 that matches its shape. The surface of the rubber sleeve 43 is provided with a plurality of fixing grooves 44 for supporting the lens 13. The inner side wall of the support cover 41 is provided with a plurality of adsorption cavities 45. The adsorption cavities 45 correspond to the fixing grooves 44 one by one, and a plurality of adsorption holes 46 are provided between the adsorption cavities 45 and the corresponding fixing grooves 44. The outer arc surface of the support cover 41 is also provided with a plurality of positioning components 7 for limiting the position of the lens 13 when it slides under pressure.

[0034] During operation, the operator can directly apply pressure to press the lens 13 into the fixing groove 44 on the surface of the rubber sleeve 43, so that the end surface of the lens 13 is in contact with the bottom of the fixing groove 44, thereby preliminarily fixing the lens 13. After all lenses 13 are installed in the fixing grooves 44 on the surface of the rubber sleeve 43, they are then connected to the external vacuum negative pressure equipment through the support pipe 42, so that the suction holes 46 at the bottom of the fixing grooves 44 generate negative pressure, vacuuming the bottom of the lens 13 and further fixing the lens 13. At the same time, the circumference of the lens 13 is limited by the positioning assembly 7. Instead of asphalt to fix the lens 13, the overall disassembly and assembly is faster and more convenient, and the elastic properties of the rubber sleeve 43 enable the groove wall to adaptively deform along with the microscopic morphology of the end face of the lens 13 when the lens 13 is pressed into the fixing groove 44, forming a "surface contact package" similar to asphalt. The contact stress is evenly dispersed through the elastic buffer of the rubber, avoiding local stress concentration caused by the "point contact" of the mechanical clamp. Vacuum adsorption forms a uniform negative pressure through the adsorption holes 46 at the bottom of the fixing groove 44, further enhancing the fitting stability of the lens 13 and the groove bottom.

[0035] It should be noted that the friction force of polishing the lens 13 is usually small, and in the technical field of this invention, the polishing of the lens 13 is usually required to be designed through a low-pressure, high-lubrication process. Its core function is to drive the abrasive particles to perform "micro-cutting" on the surface of the lens 13 rather than strong friction. This process is a well-known technology in the technical field of this invention and is not described in detail in this solution.

[0036] See Figure 3 、 Figure 4 、 Figure 7 and Figure 9 In order to prevent the positioning assembly 7 from directly and rigidly contacting the periphery of the lens 13 while ensuring that the positioning assembly 7 has sufficient limiting effect on the lens 13, the positioning assembly 7 includes a limiting ring 71 fixedly connected to the outer arc surface of the support cover 41 and slidably inserted into the rubber sleeve 43. The inner ring of the limiting ring 71 is embedded with a plurality of buffer strips 72 that slide along its circumferential direction. The side of the rubber sleeve 43 near the support cover 41 is provided with a plurality of slots 10 that are compatible with the limiting ring 71. The limiting ring 71 slides into the corresponding slots 10. The inner ring of the fixed groove 44 is provided with a plurality of connecting holes 11 along its circumferential direction that communicate with the corresponding slots 10. The buffer strips 72 are movably disposed in the connecting holes 11. The limiting ring 71 is sleeved on the circumference of the corresponding lens 13 and is fixedly connected to the support cover 41, so that the limiting ring 71 cannot move under force. At the same time, multiple buffer strips 72 installed on the circumference of the limiting ring 71 flexibly contact the lens 13 through the connecting hole 11, which has sufficient limiting effect on the lens 13, avoiding the situation where the circumference of the lens 13 is directly and rigidly contacted with the limiting ring 71 and may be damaged.

[0037] See Figure 4 、 Figure 8 、 Figure 9 and Figure 10 To facilitate the replacement of the buffer strips 72 individually, they consist of a hard, curved plastic strip 721 and a soft, curved rubber strip 722. The inner ring of the retaining ring 71 has an interlocking groove 12 along its circumference. The plastic strip 721 slides into the interlocking groove 12, and the rubber strip 722 is fixedly mounted on the inner concave surface of the plastic strip 721. Each buffer strip 72 can be directly inserted into the interlocking groove 12 of the inner ring of the retaining ring 71 through the connecting hole at the end of the fixing groove 44. The squeezing force of the connecting hole in the rubber sleeve 43 secures the buffer strip 72 to the retaining ring 71. The soft rubber strip 722 contacts the outer side of the lens 13, preventing direct, hard contact between the lens 13 and the retaining ring 71. Subsequent personnel only need to manually remove the buffer strip 72 from the end of the fixing groove 44 to replace it.

[0038] See Figure 3 、 Figure 4 、 Figure 7 and Figure 8 To facilitate replacement of the rubber sleeve 43, a notched groove is formed along the circumference of the lower edge of the rubber sleeve 43. A retaining ring 9 is fitted within the notched groove. Multiple locking bolts are rotatably mounted on the retaining ring 9 along its circumference. The locking bolts flexibly penetrate the rubber sleeve 43 and threadably connect to corresponding positions of the support cover 41. The rubber sleeve 43 engages with the retaining ring 71 via the slots 10 on its inner concave surface. The retaining ring 9 then secures the lower end of the rubber sleeve 43. The rubber sleeve 43 can then be quickly removed from the surface of the support cover 41 for replacement by rotating the locking bolts.

[0039] It should be noted that the service life of the rubber sleeve 43 and the buffer strip 72 in this solution has been obtained through multiple tests by technical personnel in this field. At the same time, the usage conditions of the two are quality inspected every week to ensure that the rubber sleeve 43 and the buffer strip 72 can maintain stable performance when the lens 13 is polished.

[0040] See Figure 2 、 Figure 3 and Figure 5The support tube 42 includes a main support tube 421 rotatably arranged on the upper side of the base 3, and a plurality of branch tubes 422 connected to the interior of the main support tube 421 are fixedly arranged. The branch tubes 422 are fixedly connected to the inner wall of the concave surface of the support cover 41 and are connected to the corresponding adsorption chamber 45. A cavity is opened inside the base 3, and two vacuum tubes 8 are fixedly arranged on the upper side of the base 3. The upper ends of the vacuum tubes 8 are rotatably connected to the main support tube 421 (the connection is sealed), and the two vacuum tubes 8 are connected to the external vacuum negative pressure equipment. The adsorption chamber 45 is evacuated by the external vacuum negative pressure equipment in conjunction with the vacuum tubes 8, so that the corresponding adsorption hole 46 generates negative pressure, and the lens 13 attached to the port position of the adsorption hole 46 is adsorbed so that the end face of the lens 13 is tightly attached to the bottom surface of the fixed groove 44. The specific structure of the vacuum negative pressure equipment and the corresponding electronic control system belong to conventional technology in this technical field and will not be introduced in detail in this scheme.

[0041] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The drive assembly 1 5 includes a motor 1 fixedly disposed within the cavity. The output shaft of the motor 1 movably extends through the upper side of the base 3 and is connected to the lower ends of the two main support tubes 421 via a sprocket assembly. The motor 1 cooperates with the sprocket assembly to drive the two main support tubes 421 to rotate, thereby controlling the rotation of the two support covers 41.

[0042] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The polishing mechanism 6 includes two rotating seats 61 rotatably arranged on the upper side of the processing table 1. A connecting plate 62 is rotatably arranged on the rotating seat 61. A spring telescopic rod 63 is arranged at the front end of the connecting plate 62. The telescopic end of the spring telescopic rod 63 is connected to the polishing cover 64 through a ball joint. An adjustment component 65 is also provided on the upper side of the rotating seat 61. A driving component 2 66 is commonly provided between the two rotating seats 61 and the processing table 1. The driving component 2 66 drives the two rotating seats 61 to rotate back and forth within a certain angle range, so that when the support cover 41 rotates and drives the lens 13 to rotate, the polishing cover 64 can slide accordingly to ensure that the polishing cover 64 can fully contact the lens 13. At the same time, the adjustment component 65 can control the separation and adhesion of the polishing cover 64 to the lens 13. A polishing pad is laid on the inner wall of the polishing cover 64, which can contact the surface of the lens 13 for polishing. At the same time, it is also necessary to spray lubricating liquid and polishing paste on the surface of the lens 13.

[0043] See Figure 1The adjustment assembly 65 includes a fixed base fixedly arranged on the upper side of the rotating base 61, and an electric push rod is hinged on the fixed base. The telescopic end of the electric push rod is hinged to the upper side of the connecting plate 62. The electric push rod is telescopically driven to drive the connecting plate 62 to rotate relative to the rotating base 61, thereby lifting the polishing cover 64.

[0044] See Figure 1 and Figure 11 The driving component 2 66 includes a driving plate 1 661 slidably set on the back of the processing table 1, and two driving pins 662 are rotatably set on the driving plate 1 661. A transmission plate 663 is fixedly set on the rear side of the rotating seat 61. A movable hole is opened on the transmission plate 663, and the driving pins 662 are movably inserted into the corresponding movable holes. A motor 2 is fixedly set on the rear side of the processing table 1, and a driving disk 664 is fixedly connected to the output shaft of the motor 2. The upper edge of the driving disk 664 is hinged to the driving plate 2 665, and the other side of the driving plate 2 665 is hinged to the driving plate 1 661. The driving plate 664 is controlled to rotate by the second motor, so that the second driving plate 665 rotates and pulls the first driving plate 661 to move back and forth. The left and right movement of the first driving plate 661 drives the transmission plate 663 through the driving pin 662 to drive the rotating seat 61 to rotate back and forth. The rotating seat 61 rotates and cooperates with the spring telescopic rod 63, so that the polishing cover 64 fits the surface of the lens 13 and rotates about the center of the lens 13 to polish the lens 13.

[0045] The entire turntable is used as follows: A worker presses the lenses 13 into the fixing grooves 44 on the surface of the rubber sleeve 43. Once all lenses 13 are placed, an external vacuum device controls the suction holes 46 to generate negative pressure, further locking the end faces of the lenses 13 at the bottom of the fixing grooves 44. The polishing cover 64 is then placed over the surface of the support cover 41 via the adjustment assembly 65. Motors 1 and 2 operate, causing the support cover 41 to rotate the lenses 13. Simultaneously, the polishing cover 64 swings back and forth in coordination with the support cover 41 to polish the lenses 13.
