Technical Field

[0001] The invention relates to the technical field of optical lens polishing, and in particular to an optical lens polishing device. Background Art

[0002] Optical lenses are lenses made of optical glass. They have specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance and light absorption, and have uniform optical properties. As a precision component, optical lenses used in precision instruments have more stringent requirements for processing accuracy. There are many processing steps for optical lenses, among which the operation of polishing the surface of the optical lens by the polishing equipment is a decisive factor in the scattering of light after the optical lens is finished.

[0048] like Figures 1 to 18 As shown, the present invention is an optical lens polishing device, comprising: a machine table 1; an optical lens body 4; a polishing mechanism 2 for polishing the optical lens body 4; and a fixing mechanism 3 for fixing the optical lens body 4.

[0049] The optical lens body 4 in the present invention is a convex lens, and the polishing mechanism 2 polishes the convex surface of the convex lens, and the convex surface of the optical lens body 4 is the polishing surface.

[0050] The polishing mechanism 2 includes: a rough polishing plate 21; a fine polishing plate 22; a power source 23 for driving the rough polishing plate 21 and the fine polishing plate 22 to rotate, and the power source 23 is fixedly installed on the mounting frame 252; an adjustment component 24 for adjusting the position of the rough polishing plate 21 and the fine polishing plate 22; a moving component 25 for driving the rough polishing plate 21 and the fine polishing plate 22 to move; and a cooling component 26 for cooling the optical lens body 4.

[0051] When polishing the optical lens body 4, it is necessary to perform rough polishing first and then fine polishing, so a rough polishing plate 21 and a fine polishing plate 22 are set; the rough polishing plate 21 or the fine polishing plate 22 can be driven to move by the moving component 25, so that the rough polishing plate 21 or the fine polishing plate 22 abuts against the polishing surface of the optical lens body 4; at this time, by starting the power source 23, the rough polishing plate 21 and the fine polishing plate 22 are driven to rotate, thereby realizing the rough polishing and fine polishing of the optical lens body 4.

[0052] It is to be added here that the power source 23 is preferably: a motor.

[0053] The moving assembly 25 includes: a fixed box 251 fixedly installed on the machine 1; a mounting frame 252 slidably installed on the fixed box 251, a limited opening is provided on the fixed box 251, and the mounting frame 252 is slidably installed in the limited opening; a power source 253 that drives the mounting frame 252 to move, and the power source 253 is fixedly installed on the fixed box 251; a guide member 254 that guides the mounting frame 252; the guide member 254 includes: a guide rail 2541 fixedly installed on the fixed box 251; a guide block 2542 slidably installed on the guide rail 2541; the guide block 2542 is fixedly connected to the mounting frame 252.

[0054] Specifically, by starting the power source three 253, the mounting frame 252 can be driven to move. During the movement of the mounting frame 252, the guide block 2542 can be driven to slide on the guide rail 2541. Through the setting of the guide member 254 and the limit opening, the mounting frame 252 can be double-limited during the movement, thereby ensuring the stability of the mounting frame 252 during movement.

[0055] By moving the mounting frame 252, the rough polishing plate 21 and the fine polishing plate 22 can be driven to move, so that the rough polishing plate 21 or the fine polishing plate 22 abuts against the polishing surface of the optical lens body 4, thereby preparing for subsequent polishing.

[0056] It is to be added here that the power source three 253 is preferably: a cylinder.

[0057] The positions of the rough polishing plate 21 and the fine polishing plate 22 can be adjusted by the adjustment component 24, so as to achieve the rough polishing and fine polishing of the optical lens body 4. The adjustment component 24 includes: a cylinder 241 rotatably mounted on the mounting frame 252, and the cylinder 241 is fixedly connected to the output shaft of the power source 23; a linkage gear 242 rotatably mounted in the cylinder 241; and a linkage rack 243 meshingly connected with the linkage gear 242, and the linkage rack 243 is provided with two, which are symmetrically arranged on the linkage gear 242. on both sides; a power source 244 driving the linkage rack 243 to move, the power source 244 is fixedly installed in the cylinder 241, and the telescopic end of the power source 244 is fixedly connected to any one of the linkage racks 243; a limiter 245 for limiting the linkage rack 243; the rough polishing plate 21 and the fine polishing plate 22 are both fixedly connected to the linkage rack 243; the bottom end of one linkage rack 243 is fixedly connected to the rough polishing plate 21, and the bottom end of the other linkage rack 243 is fixedly connected to the fine polishing plate 22.

[0058] It is to be added here that the power source 244 is preferably: an electric telescopic rod.

[0059] The limiting member 245 includes: a slide rail 2451 fixedly installed in the cylinder 241; a slider 2452 slidably installed on the slide rail 2451; a slide groove opened in the cylinder 241; a slide bar 2453 slidably installed in the slide groove; the slider 2452 and the slide bar 2453 are both fixedly connected to the linkage rack 243; when the linkage rack 243 moves, it can drive the slider 2452 to slide on the slide rail 2451, and at the same time drive the slide bar 2453 to slide in the slide groove. Through the setting of the limiting member 245, the linkage rack 243 can be doubly limited, thereby ensuring the stability of the linkage rack 243 when moving, and further ensuring the stability of the rough polishing plate 21 and the fine polishing plate 22 when moving.

[0060] In addition, when the rough polishing plate 21 and the fine polishing plate 22 rotate, the power source 23 is started to drive the cylinder 241 to rotate, and the cylinder 241 drives the limit member 245 to rotate, thereby driving the rough polishing plate 21 and the fine polishing plate 22 to rotate. The setting of the limit member 245 is also guaranteed to ensure the stability of the rough polishing plate 21 and the fine polishing plate 22 during rotation, thereby ensuring the polishing accuracy.

[0061] When the adjacent interlocking rack 243 is driven to move downward by starting power source 244, the interlocking rack 243 drives the interlocking gear 242 to rotate, thereby driving the other interlocking gear 242 to move upward; when the power source 244 drives the adjacent interlocking rack 243 to move upward, the interlocking rack 243 drives the interlocking gear 242 to rotate in the opposite direction, thereby driving the other interlocking gear 242 to move downward; since the bottom end of one of the two interlocking racks 243 is fixedly connected to the rough polishing plate 21, the bottom end of the other interlocking rack 243 is fixedly connected to the fine polishing plate 22.

[0062] Therefore, when the rough polishing plate 21 moves downward, the fine polishing plate 22 moves upward; similarly, when the rough polishing plate 21 moves upward, the fine polishing plate 22 moves downward; thereby, when the optical lens body 4 is rough-polished, the rough polishing plate 21 moves downward, and when the optical lens body 4 is fine-polished, the fine polishing plate 22 moves downward; thereby, the positions of the rough polishing plate 21 and the fine polishing plate 22 are adjusted, so that the present invention can realize both the rough polishing of the optical lens body 4 and the fine polishing of the optical lens body 4.

[0063] The cooling assembly 26 includes: a liquid storage tank 261 fixedly mounted on the mounting frame 252; an annular tube 262 fixedly mounted on the mounting frame 252; a hose 263 connected to the annular tube 262; a liquid spray head 264 connected to the hose 263, and the hose 263 and the liquid spray head 264 are provided with multiple groups, and are evenly distributed along the circumference of the annular tube 262, thereby expanding the spray range of the liquid spray head 264 and improving the cooling effect on the optical lens body 4; a suction unit 265 that absorbs the cooling liquid in the liquid storage tank 261 into the annular tube 262; the suction unit 265 includes: a fixed tube 2651 fixedly mounted on the mounting frame 252; a piston 2652 slidably mounted in the fixed tube 2651; a movable rod 2653 fixedly connected to the piston 2652, and the mounting frame A limit hole is provided on 252, and a movable rod 2653 is slidably installed in the limit hole; a circular ring 2654 is slidably installed on the cylinder 241, and the bottom end of the movable rod 2653 passes through the side wall of the fixed cylinder 3685 and is fixedly connected to the circular ring 2654; a rolling member 2655 is rotatably installed in the circular ring 2654; a guide groove 2656 is provided on the cylinder 241, and the guide groove 2656 consists of two U-shaped grooves in opposite directions and interconnected, and a rolling member 2655 is rotatably installed in the guide groove 2656; a liquid inlet pipe 2657 connecting the fixed pipe 2651 and the liquid storage tank 261, and a first one-way valve is installed on the liquid inlet pipe 2657; a liquid outlet pipe 2658 connecting the fixed pipe 2651 and the annular pipe 262, and a second one-way valve is installed on the liquid outlet pipe 2658.

[0064] When the power source 23 is started to drive the cylinder 241 to rotate, and then drive the rough polishing plate 21 or the fine polishing plate 22 to polish the optical lens body 4, the guide groove 2656 can be set to drive the rolling member 2655 to move, and the rolling member 2655 drives the ring 2654 to move. Through the mutual cooperation of the movable rod 2653 and the limiting hole, the ring 2654 can be limited, so that the ring 2654 can move up and down along the axis of the cylinder 241, and the movable rod 2653 follows the ring 2654 to move up and down, thereby driving the piston 2652 to move up and down in the fixed tube 2651.

[0065] When the piston 2652 moves downward in the fixed tube 2651, the first one-way valve opens and the second one-way valve closes. At this time, the coolant in the liquid storage tank 261 is sucked into the fixed tube 2651 through the liquid inlet pipe 2657. When the piston 2652 moves upward in the fixed tube 2651, the first one-way valve closes and the second one-way valve opens. At this time, the coolant in the fixed tube 2651 is squeezed and flows into the spray head 264 through the liquid outlet pipe 2658, the annular tube 262, and the hose 263 in turn, and is sprayed on the polishing surface of the optical lens body 4 through the spray head 264, so that the optical lens body 4 can be cooled, and the heat generated during the polishing process can be effectively absorbed and taken away, so as to prevent the optical lens body 4 from being deformed or damaged due to overheating, thereby improving the polishing quality.

[0066] When polishing the optical lens body 4, it is necessary to perform rough polishing first and then fine polishing. The goal of the rough polishing stage is to quickly remove larger unevenness on the surface of the optical lens body 4 and contaminants attached to the surface of the optical lens body 4. Therefore, a higher polishing speed is usually selected during rough polishing to speed up the process and improve efficiency; a higher polishing speed helps to cover a larger polishing area in a short time, thereby shortening the overall polishing time; however, in the fine polishing stage, the goal is to further improve the smoothness and precision of the surface of the optical lens body 4 and remove minor flaws left in the rough polishing stage; in order to achieve a finer surface treatment, the polishing speed is usually reduced during fine polishing; a slower polishing speed helps to better control the polishing depth and uniformity to ensure that the required surface quality is achieved.

[0067] It can be seen from the above that when the optical lens body 4 is finely polished and roughly polished, the rotation speed requirements of the fine polishing plate 22 and the rough polishing plate 21 are different.

[0068] Since rough polishing requires a higher rotation speed and greater polishing force, relatively more heat is generated during the polishing process, so a relatively large spray volume of coolant is required; the rotation speed and polishing force of fine polishing will be reduced, and the friction heat generated is relatively small, so a relatively small spray volume of coolant is required.

[0069] When the optical lens body 4 is rough-polished, the power source 23 drives the rough-polishing plate 21 to rotate at a relatively fast speed, thereby driving the piston 2652 to move up and down at a fast frequency, thereby increasing the amount of coolant sprayed.

[0070] When fine polishing the optical lens body 4, the power source 23 drives the fine polishing plate 22 to rotate at a relatively slow speed, thereby driving the piston 2652 to move up and down at a slow frequency, thereby reducing the amount of coolant sprayed.

[0071] It should be added that fine polishing does not require a large amount of coolant spraying like rough polishing, because excessive coolant spraying may affect the friction of the fine polishing plate 22, reduce the polishing efficiency, and may even leave water marks on the material surface or cause other adverse effects.

[0072] In the present invention, through the setting of the cooling component 26, the rotation speed of the power source 23 can be adjusted according to the rough polishing section and the fine polishing section of the optical lens body 4, thereby adjusting the rotation speed of the rough polishing plate 21 and the fine polishing plate 22, and then synchronously adjusting the spraying amount of the coolant, thereby realizing automatic adjustment of the coolant flow rate in different polishing stages to meet the requirements of the coolant flow rate in different polishing stages.

[0073] The cooling assembly 26 also includes: a linkage rod 267 hingedly mounted on the ring 2654 ; a replenishing unit 266 for replenishing the liquid storage tank 261 with cooling liquid; and the other end of the linkage rod 267 is hingedly connected to the liquid spray head 264 .

[0074] When the ring 2654 moves up and down, it can drive the connecting rod 267 to move, and the connecting rod 267 can drive the spray head 264 to swing, that is, multiple spray heads 264 gather inward or expand outward at the same time, thereby further expanding the spraying range of the spray head 264, and further improving the cooling effect on the optical lens body 4.

[0075] The replenishing unit 266 includes: a cooling box 2661 fixedly installed in the machine 1; a liquid storage cylinder 2662 fixedly installed in the fixed box 251; a piston 2663 slidably installed in the liquid storage cylinder 2662; a connecting rod 2664 fixedly connected to the piston 2663; the top end of the connecting rod 2664 passes through the inner cavity of the liquid storage cylinder 2662 and is fixedly connected to the mounting frame 252; a liquid inlet pipe 2665 connecting the liquid storage cylinder 2662 and the cooling box 2661, and a third one-way valve is installed on the liquid inlet pipe 2665; a liquid outlet pipe 2666 connecting the liquid storage cylinder 2662 and the liquid storage tank 261, and a fourth one-way valve is installed on the liquid outlet pipe 2666.

[0076] When the mounting bracket 252 moves downward, the connecting rod 2664 is driven to move downward, and the connecting rod 2664 drives the second piston 2663 to slide downward in the inner cavity of the liquid storage cylinder 2662, thereby squeezing the coolant in the liquid storage cylinder 2662. At this time, the third one-way valve is closed, and the fourth one-way valve is opened, and the coolant enters the liquid storage tank 261 through the second liquid outlet pipe 2666, thereby replenishing the coolant in the liquid storage tank 261.

[0077] When the mounting bracket 252 moves upward, it drives the connecting rod 2664 upward, and the connecting rod 2664 drives the piston 2663 to slide upward in the inner cavity of the liquid storage cylinder 2662, thereby causing negative pressure in the liquid storage cylinder 2662. At this time, the third one-way valve opens, and the fourth one-way valve closes, and the coolant in the cooling box 2661 enters the liquid storage cylinder 2662 through the liquid inlet pipe, preparing for subsequent replenishment.

[0078] It should be added here that the cooling box 2661 is connected to a cold source, which can cool the coolant in the cooling box 2661.

[0079] The fixing mechanism 3 includes: a support column 31 rotatably mounted on the machine 1; a mounting base 32 fixedly mounted on the top of the support column 31; a transmission gear ring 34 fixedly sleeved on the support column 31; a transmission gear 33 meshingly connected to the transmission gear ring 34; a power source 35 that drives the transmission gear 33 to rotate, and the power source 35 is fixedly mounted on the machine 1; a clamping assembly 36 for clamping and fixing the optical lens body 4; and a supporting assembly 37 for supporting the optical lens body 4.

[0080] The clamping assembly 36 and the supporting assembly 37 in the present application are both provided with two groups. Therefore, the optical lens body 4 to be polished can be clamped and fixed by any group of the clamping assembly 36, and the power source 4 35 is started to drive the transmission gear 33 to rotate, the transmission gear 33 drives the transmission gear ring 34 to rotate, the transmission gear ring 34 drives the support column 31 to rotate, and the support column 31 drives the mounting seat 32 to rotate, thereby driving the two groups of clamping assemblies 36 to rotate, and rotating one group of clamping assemblies 36 on which the optical lens body 4 is placed to the polishing position, and then starting the polishing mechanism 2 to polish the optical lens body 4. At the same time, the staff can fix the optical lens body 4 by another group of clamping assemblies 36 to prepare for subsequent polishing.

[0081] From the above, it can be known that two groups of clamping assemblies 36 are provided in the present invention, thereby having two fixed workstations. By starting the power source four 35, the optical lens bodies 4 on the two fixed workstations can be moved to the polishing position for polishing in turn, so that the polished optical lens body 4 can be manually removed and the optical lens body 4 to be polished can be placed, and polishing work can also be performed, thereby improving the polishing efficiency.

[0082] It is to be added here that the power source four 35 is preferably: an electric motor.

[0083] The clamping assembly 36 includes: a mounting groove 361 provided on the mounting seat 32; a placement plate 362 fixedly installed in the mounting groove 361, the placement plate 362 being located at the center of the bottom of the inner cavity of the mounting groove 361; a liquid collecting pipe 363 plugged and installed in the mounting groove 361; a piston three 364 slidably installed in the liquid collecting pipe 363; a clamping rod 365 fixedly connected to the piston three 364, the other end of the clamping rod 365 passing through the inner cavity of the liquid collecting pipe 363; a clamping plate 366 fixedly connected to the other end of the clamping rod 365; a reset spring 367 for driving the clamping plate 366 to reset, one end of the reset spring 367 being fixedly connected to the piston three 364, and the other end being fixedly connected to the inner wall of the liquid collecting pipe 363; and a liquid supply unit 368 for conveying cooling liquid into the liquid collecting pipe 363.

[0084] When clamping and fixing the optical lens body 4, first place the optical lens body 4 on the placement plate 362, then start the power source 4 35 to drive the transmission gear 33 to rotate, the transmission gear 33 drives the transmission gear ring 34 to rotate, the transmission gear ring 34 drives the support column 31 to rotate, and then drives the liquid supply unit 368 to transport cooling liquid into the liquid collecting pipe 363.

[0085] The liquid supply unit 368 includes: a liquid storage tube 3681 fixedly mounted at the bottom end of the support column 31; a piston 3682 slidably mounted in the liquid storage tube 3681; a moving rod 3683 fixedly connected to the piston 3682; a rolling element 3684 rotatably mounted on the moving rod 3683; a fixed cylinder 3685 fixedly mounted in the cooling box 2661, and the bottom end of the moving rod 3683 penetrates the inner cavity of the liquid storage tube 3681 and extends to the fixed cylinder 3685; a guide groove 3686 provided in the fixed cylinder 3685, the guide groove 3686 consisting of two U-shaped grooves in opposite directions and interconnected; a rolling element 3684 rollingly mounted in the guide groove 3686; a liquid dispensing tube 3687 fixedly mounted at the bottom of the mounting seat 32; a liquid guide tube 1 3688 connecting the liquid storage tube 3681 and the liquid dispensing tube 3687; a liquid guide tube 2 3689 connecting the liquid dispensing tube 3687 and the liquid collecting tube 363.

[0086] The liquid storage tube 3681 is divided into two independent spaces, upper and lower, by the piston four 3682, and coolant is stored above the piston four 3682.

[0087] When the support column 31 rotates, the two liquid storage tubes 3681 can be driven to rotate, and the two liquid storage tubes 3681 drive the adjacent moving rods 3683 to rotate, and the two moving rods 3683 drive the adjacent rolling element 2 3684 to move along the path of the guide groove 3686.

[0088] In the initial state, one of the two groups of clamping assemblies 36 is located at the loading position, and the other group is located at the polishing position. The positions of the two groups of clamping assemblies 36 correspond to the positions of the adjacent liquid storage tubes 3681, as shown in the attached figure. Fig.18As shown, the position of the liquid storage tube 3681 on the left side corresponds to the position of the clamping assembly 36 at the loading position, and the liquid storage tube 3681 on the right side corresponds to the position of the clamping assembly 36 at the polishing position. At the same time, the second rolling element 3684 on the left side is located at the lowest point of the guide groove 3686, and the second rolling element 3684 on the right side is located at the highest point of the guide groove 3686.

[0089] When the optical lens body 4 is placed in the clamping assembly 36 located at the loading position, the power source four 35 is started to interchange the positions of the two clamping assemblies 36. At this time, the rolling element 2 3684 located on the left side rolls from the lowest point of the guide groove 3686 to the highest point of the guide groove 3686, and the rolling element 2 3684 located on the right side rolls from the highest point of the guide groove 3686 to the lowest point of the guide groove 3686.

[0090] When the rolling element 2 3684 on the left side rolls from the lowest point of the guide groove 3686 to the highest point of the guide groove 3686, the moving rod 3683 is driven to move upward, and the moving rod 3683 drives the piston 4 3682 to move upward. When the piston 4 3682 moves upward, the coolant in the liquid storage tube 3681 is squeezed, so that the coolant enters the liquid distribution tube 3687 through the liquid guide tube 1 3688, and enters the liquid collection tube 363 through the liquid guide tube 2 3689. When the amount of coolant gradually increases, the hydraulic action of the coolant can drive the piston three 364 to slide in the collecting pipe 363, thereby driving the clamping rod 365 to move, and the clamping rod 365 drives the clamping plate 366 to approach the optical lens body 4, and drives the reset spring 367 to deform. When the rolling element 2 3684 on the left side rolls to the highest point of the guide groove 3686, the clamping plate 366 just presses against the side wall of the optical lens body 4, thereby achieving the clamping and fixation of the optical lens body 4.

[0091] The clamping plates 366 in the present invention are provided with multiple groups, which can clamp and fix the optical lens body 4 from different directions, thereby improving the stability of the fixation of the optical lens body 4, thereby avoiding displacement of the optical lens body 4 during polishing and improving the polishing quality.

[0092] In addition, the clamping plate 366 is L-shaped, and can clamp and fix the outer edge and the top of the optical lens body 4 at the same time, thereby further improving the stability of the fixation of the optical lens body 4.

[0093] When the optical lens body 4 is polished, the clamping assembly 36 at the polishing position moves to the loading position, and the rolling element 2 3684 rolls from the highest point of the guide groove 3686 to the lowest point of the guide groove 3686, thereby driving the moving rod 3683 to move downward, and the moving rod 3683 drives the piston 4 3682 to move downward, so that the coolant in the collecting pipe 363 can be sucked into the liquid storage pipe 3681. At this time, the elastic force of the reset spring 367 can drive the piston 364 to reset, and then drive the clamping plate 366 to reset, thereby releasing the fixed state of the optical lens body 4, and making it convenient for the staff to take out the polished optical lens body 4 and replace the optical lens body 4 to be polished.

[0094] In the present invention, by setting up the fixing mechanism 3, the optical lens bodies 4 on the two fixed stations are moved to the polishing place for polishing in turn, and then the polishing work can be carried out while the polished optical lens body 4 is manually removed and the optical lens body 4 to be polished is placed, thereby improving the polishing efficiency, and the optical lens body 4 to be polished is fixed while being moved to the polishing place, and at the same time, the optical lens body 4 that has been polished is moved to the loading place and the optical lens body 4 is released from fixation, so that the staff can take out and replace the optical lens body 4 to be polished.

[0095] It should be added here that since the liquid storage tube 3681 is located in the coolant of the cooling box 2661, the coolant in the liquid storage tube 3681 can be cooled by the coolant in the cooling box 2661, and a circular hole is provided on the side wall of the liquid storage tube 3681 near the bottom end. When the piston four 3682 moves upward, the coolant in the cooling box 2661 can be sucked into the liquid storage tube 3681 through the circular hole. When the piston four 3682 moves downward, the sucked coolant is sprayed into the cooling box 2661 through the circular hole, thereby mixing the coolant in the cooling box 2661, so that the cold source cools the coolant in the cooling box 2661 evenly.

[0096] The support assembly 37 includes: a sac 371 fixedly mounted on the placement plate 362; a liquid guide tube 375 connecting the sac 371 and the liquid dispensing tube 3687; a nozzle 374 connected to the sac 371, and the sac 371 and the nozzle 374 are connected through an air guide tube 373; the sac 371 is arranged in an arc shape, and a partition 372 is fixedly mounted inside the sac 371, and the sac 371 is divided into two independent spaces by the partition 372, one space for storing coolant and the other space for storing air; and the partition 372 is made of the same material as the sac 371, both of which are made of soft and durable materials (such as latex or silicone) and have good expandability; the liquid guide tube 375 is connected to the space of the sac 371 for storing coolant; the air guide tube 373 is connected to the space of the sac 371 for storing air.

[0097] When piston four 3682 moves upward, it squeezes the coolant in the liquid storage tube 3681, so that the coolant enters the distribution tube 3687 through the liquid guide tube one 3688, and enters the liquid collecting tube 363 through the liquid guide tube two 3689 on the one hand, and enters the coolant storage space of the capsule 371 through the liquid guide tube three 375 on the other hand. When the coolant in the capsule 371 gradually increases, the capsule 371 expands. The expanded capsule 371 is tightly attached to the inner wall of the optical lens body 4, thereby supporting the optical lens body 4, thereby further improving the stability of the optical lens body 4.

[0098] At the same time, the coolant squeezes the interlayer 372, thereby squeezing the air in the air storage space, and the air enters the nozzle 374 through the air duct 373, and is sprayed on the polished surface of the optical lens body 4 through the nozzle 374, so that the dust attached to the polished surface of the optical lens body 4 can be blown away, thereby realizing the dust cleaning of the polished surface of the optical lens body 4 before polishing, avoiding the possibility that dust may be embedded in the surface of the optical lens body 4 during the polishing process, forming scratches or defects, and affecting the polishing quality.

[0099] In addition, the expanded capsule 371 is tightly attached to the inner wall of the optical lens body 4, and the coolant in the capsule 371 can cool the inner side of the optical lens body 4, effectively absorbing and taking away the heat generated during the polishing process, preventing the optical lens body 4 from being deformed or damaged due to overheating, and further improving the polishing quality.

[0100] In the present invention, the expansion of the capsule 371, on the one hand, supports the optical lens body 4, further improving the stability of the optical lens body 4; on the other hand, cools the inner side of the optical lens body 4, effectively absorbs and takes away the heat generated during the polishing process, prevents the optical lens body 4 from being deformed or damaged due to overheating, and further improves the polishing quality; at the same time, the polishing surface of the optical lens body 4 is cleaned of dust before polishing, avoiding the possibility that dust may be embedded in the surface of the optical lens body 4 during the polishing process, forming scratches or defects, and affecting the polishing quality.

[0101] Through the cooperation between the capsule 371 and the cooling component 26, the outer side and the inner side of the optical lens body 4 can be cooled down at the same time when the optical lens body 4 is polished, effectively absorbing and taking away the heat generated during the polishing process, preventing the optical lens body 4 from being deformed or damaged due to overheating, and improving the polishing quality.

[0102] The polishing mechanism 2 further includes: a recovery component 27 for recovering the coolant;

[0103] The recovery component 27 includes: an annular groove 271 provided at the bottom of the inner cavity of the mounting groove 361; a through hole 272 provided on the mounting seat 32, wherein a plurality of through holes 272 are provided and evenly distributed along the circumference of the annular groove 271, and the through hole 272 is connected to the annular groove 271; a collecting frame 273 fixedly installed on the machine 1, wherein a plurality of circular openings are provided on the machine 1, and the plurality of circular openings are all connected to the collecting frame 273; a filter screen 274 fixedly installed in the collecting frame 273, wherein the filter screen 274 is a plate-shaped filter screen 274; a long shaft 275 rotatably installed on the machine 1 and the filter screen 274; a positioning bar 276 fixedly installed on the long shaft 275; a movable cylinder 277 sleeved and installed on the long shaft 275, wherein a positioning groove matching the positioning bar 276 is provided on the movable cylinder 277; a cleaning member 278 fixedly installed on the movable cylinder 277; and a stirring unit 279 for stirring the coolant in the cooling box 2661.

[0104] The coolant sprayed on the surface of the optical lens body 4 and the mixed liquid formed by the waste chips generated during polishing flow into the annular groove 271 and flow into the collecting frame 273 through the through hole 272. Since there are multiple through holes 272, the discharge efficiency of the mixed liquid is improved. The waste chips in the mixed liquid can be filtered through the filter net 274. The filtered coolant flows into the cooling box 2661 through the circular opening, thereby realizing the recovery of the coolant and recycling it, thereby improving the utilization rate of the coolant.

[0105] The cleaning part 278 includes: a filter tube 2781 fixedly mounted on the movable cylinder 277, the filter tube 2781 is a tubular filter screen 274; a collecting hopper 2782 connected to the filter tube 2781, the collecting hopper 2782 and the filter screen 274 are arranged to fit each other; the filter tube 2781 is fixedly connected to the collecting hopper 2782; the stirring unit 279 includes: a stirring blade 2791 fixedly mounted on the long shaft 275; a synchronous gear 2792 fixedly mounted on the long shaft 275; a synchronous gear ring 2793 fixedly mounted on the support column 31; and a synchronous belt 2794 meshingly connected to the synchronous gear 2792 and the synchronous gear ring 2793.

[0106] When the support column 31 rotates, the synchronous gear ring 2793 can be driven to rotate, the synchronous gear ring 2793 can drive the synchronous belt 2794 to rotate, and the synchronous belt 2794 can drive the synchronous gear ring 2793 to rotate, thereby driving the long shaft 275 to rotate, and then driving the stirring blade 2791 and the cleaning piece 278 to rotate synchronously. Through the rotation of the stirring blade 2791, the coolant in the cooling box 2661 can be stirred, so that the cold source can further cool the coolant in the cooling box 2661 evenly.

[0107] Since the collecting hopper 2782 and the filter screen 274 are arranged to fit each other, the collecting hopper 2782 can scrape up the waste debris on the filter screen 274 through the rotation of the cleaning member 278, and the scraped waste debris enters the filter tube 2781 for collection, thereby achieving the cleaning of the filter screen 274 and avoiding the accumulation of waste debris on the surface of the filter screen 274, causing the filter screen 274 to be blocked and affecting the filtering effect.

[0108] Furthermore, since the filter tube 2781 is a tubular filter screen 274 , the coolant contained in the waste chips can be filtered out through the filter screen 274 .

[0109] When a certain amount of waste debris is collected in the filter tube 2781, the movable cylinder 277 is pulled upward to separate the positioning bar 276 from the positioning groove, so that the filter tube 2781 can be disassembled, and the filter tube 2781 can be cleaned conveniently. After the filter tube 2781 is cleaned, the positioning groove of the movable cylinder 277 is aligned with the positioning bar 276, and the movable cylinder 277 is sleeved on the positioning bar 276, so as to complete the installation of the filter tube 2781. When the long shaft 275 rotates, the cleaning piece 278 can be driven to rotate again, and the filter screen 274 can be cleaned, so that the present invention can realize automatic cleaning of the filter screen 274 without stopping the machine, and there is no need to disassemble and clean the filter screen 274, and it is convenient to clean the waste debris collected in the cleaning piece 278, thereby improving the polishing efficiency.

[0110] It should be added here that the diameter of the synchronous gear ring 2793 is much larger than the diameter of the synchronous gear ring 2793. When the synchronous gear ring 2793 rotates one circle, the synchronous gear ring 2793 can rotate several circles, thereby driving the long shaft 275 to rotate several circles, and then driving the stirring blade 2791 to rotate several circles, thereby improving the stirring effect on the coolant.
