Description

Technical Field

[0001] This invention relates to the field of optical lens processing technology, specifically to an optical lens grinding device with a scratch-resistant clamping mechanism. Background Technology

[0002] Optical lenses, as core functional components in optical instruments, photographic equipment, medical testing, automotive optics, and optoelectronic communication, are widely used in critical scenarios such as precision imaging, laser transmission, signal coupling, and visual recognition. Their surface finish, surface accuracy, edge integrity, and undamaged state directly determine the imaging clarity, optical path stability, transmission efficiency, and reliability of the entire optical system. In the finishing process after lens forming, grinding is the core process that determines the final processing quality. It not only requires high-precision surface correction but also must avoid scratches, indentations, chipping, and stress deformation of the lens during clamping, positioning, and processing.

[0003] Existing optical lens grinding devices mostly employ a single rotation or linear motion during the grinding process. The grinding trajectory is singular and the coverage is limited, which can easily lead to over-grinding in certain areas of the lens and uneven removal of material between the center and the edges, resulting in low surface accuracy and insufficient smoothness. Because the grinding disc is fixed in position, it is easy for the grinding disc to not cover the lens completely when grinding optical lenses of different diameters, resulting in insufficient grinding. At the same time, grinding devices mostly use rigid pressing, single-point or double-sided clamping to fix the lens, which can easily cause indentations, scratches or even chipping on the lens edges and surfaces during clamping and rotation, making it difficult to meet the requirements of non-destructive processing of high-precision optical lenses.

[0004] Based on this, the present invention designs an optical lens grinding device with a scratch-resistant clamping mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an optical lens grinding device with an anti-scratch clamping mechanism to solve the problems mentioned in the background art. Existing optical lens grinding devices often use a single rotation or linear motion during the grinding process, resulting in a single grinding trajectory and limited coverage. This can easily lead to over-grinding of localized areas of the lens, uneven removal of the center and edges, and consequently, low surface accuracy and insufficient smoothness. Furthermore, due to the fixed position of the grinding disc, incomplete coverage of the grinding disc is common when grinding optical lenses of different diameters, resulting in insufficient lens grinding. Additionally, grinding devices often use rigid pressing, single-point or double-sided clamping to fix the lens, which can easily cause indentations, scratches, or even chipping on the lens edges and surfaces during clamping and rotation, making it difficult to meet the requirements for non-destructive processing of high-precision optical lenses.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

A connecting column is fixedly installed at the top between the two moving frames.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, by setting up a rotating crank frame, a push column, a movable slide plate, a clamping spring, a clamping spring, and a drive gear, controls the extension and retraction of an electric push rod based on the diameter of the optical lens body and the grinding range. This drives the push frame to move along the push slide groove, and drives the rotating crank frame to rotate around a pin between the mounting side plates. During the rotation, the push column slides within the movable slide groove, pushing the movable frame and the connecting column to move synchronously. This, in turn, drives the movable slide plate to precisely adjust its lateral position within the rectangular through slot, aligning the grinding disc with the area to be ground on the optical lens body. When the movable slide plate is adjusted, the clamping spring continuously rebounds and pushes the reset movable seat, causing the reset movable seat to move along the mounting slide rod and the movable roller to roll within the limiting slide groove, keeping the guide transmission wheel constantly tensioned. The transmission belt ensures that there is no slippage or loosening between the main drive wheel, the auxiliary drive wheel, and the guide drive wheel. When the grinding motor starts, the main drive wheel rotates through the meshing of bevel gear one and bevel gear two. This drives the auxiliary drive wheel to rotate synchronously via the transmission belt. The auxiliary drive wheel drives the connecting plate and the mounting sleeve to revolve around the fixed gear ring, causing the grinding disc to move in a circular trajectory along the surface of the optical lens. When the mounting sleeve revolves, the drive gear and the fixed gear ring continuously mesh, driving the mounting column to rotate within the mounting sleeve, which in turn drives the grinding disc to rotate at high speed. Ultimately, this achieves a composite grinding process of revolution and rotation of the grinding disc on the surface of the optical lens. This ensures that the revolution of the grinding disc covers the entire lens, while the rotation of the grinding disc improves grinding efficiency and surface finish, and avoids over-grinding in certain areas.

[0018] 2. This invention, through its design, selects a matching clamping and fixing mechanism based on the specifications of the optical lens body. The cross-shaped mounting bracket is placed flush against the top of the mounting plate, aligning the positioning blocks on the mounting plate with and engaging the positioning slots at the bottom of the cross-shaped mounting bracket, achieving rapid radial positioning. Under the rebound force of the arc-shaped fixing spring, the L-shaped fixing plate rotates around the pin and locks itself in the fixing slot, firmly locking the cross-shaped mounting bracket onto the mounting plate. This completes the rapid assembly of the clamping and fixing mechanism. The optical lens body is then stably placed at the center of the area enclosed by the four clamping posts on top of the cross-shaped mounting bracket. The electric push rod is then activated. The telescopic end drives the fixed stud and the cross linkage frame to rise and fall synchronously, driving the four sets of rotating clamping frames to retract inward around the pin shaft, so that the clamping pins are evenly attached to the edge of the optical lens body and complete the centering clamping. The clamping force is balanced and the contact area is small, avoiding scratching the lens surface. After clamping, the drive motor is started to drive the drive turntable to rotate, and the linkage bar drives the two linkage turntables to rotate synchronously. The linkage turntable drives the connecting sleeve to rotate stably in the fixed frame, thereby making the mounting plate, clamping and fixing mechanism and the optical lens body rotate synchronously and uniformly, ensuring that the surface of the optical lens body is evenly attached to the grinding plate and achieving continuous and stable grinding.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-13 The present invention provides a technical solution:

[0037] An optical lens grinding device with an anti-scratch clamping mechanism includes a processing box 1. Processing grooves 2 are symmetrically arranged on both sides of the top of the processing box 1. Drainage racks 3 are symmetrically fixedly installed on the bottom of the outer surface of the processing box 1, and the two drainage racks 3 are respectively connected to the positions of the processing grooves 2. A grinding rotating mechanism 4 is rotatably installed at the center of the bottom of the processing box 1 via a bearing. Both ends of the grinding rotating mechanism 4 extend through the bottom of the processing box 1 into the processing grooves 2. Clamping and fixing mechanisms 5 are respectively inserted and installed at the two ends of the grinding rotating mechanism 4 inside the processing grooves 2. An optical lens body 6 is provided on the top of the clamping and fixing mechanism 5. Electric lifting rods 7 are respectively embedded and fixedly installed at the four corners of the top of the processing box 1. A top cover 8 is fixedly installed at the output end of the four electric lifting rods 7. Moving grinding mechanisms 9 are symmetrically slidably installed on both sides of the top of the top cover 8 corresponding to the positions of the processing grooves 2. Adjustment mechanisms 10 are fixedly installed on both sides of the top of the top cover 8.

[0038] During operation, the corresponding clamping and fixing mechanism 5 is matched according to the specifications of the optical lens body 6 and quickly installed on the top of the grinding rotation mechanism 4 to complete the centering and scratch-proof clamping of the optical lens body 6. Then, the electric lifting rod 7 drives the top cover 8 to descend, so that the moving grinding mechanism 9 fits against the surface of the optical lens body 6. The grinding position of the moving grinding mechanism 9 is adjusted by the adjusting mechanism 10, and the moving grinding mechanism 9 is started to perform compound grinding of revolution and rotation. At the same time, the grinding rotation mechanism 4 drives the optical lens body 6 to rotate synchronously for grinding. Coolant is sprayed onto the optical lens body 6 and flows into the processing tank 2. The grinding coolant is discharged with the drainage rack 3 to achieve efficient, uniform and scratch-free grinding of the optical lens body 6.

[0039] As a further embodiment of the present invention, the grinding rotation mechanism 4 includes a drive motor 401, which is embedded and fixedly installed at the center of the bottom of the processing box 1. A drive turntable 402 is fixedly installed at the output end of the bottom of the drive motor 401. A linkage bar 403 is rotatably installed at the bottom edge of the drive turntable 402 via a protrusion. Linkage turntables 404 are rotatably installed at both ends of the linkage bar 403 via protrusions. A connecting sleeve 405 is fixedly installed at the top of the linkage turntable 404. A fixing frame 406 is rotatably installed at the bottom of the surface of the connecting sleeve 405 via a bearing. The fixing frame 406 is fixedly connected to the center of the bottom of the processing box 1 at the bottom of the processing groove 2. An electric push rod 407 is embedded and fixedly installed at the top of the connecting sleeve 405. A mounting plate 408 is fixedly installed at the top of the connecting sleeve 405. The top end of the electric push rod 407 passes through the center of the mounting plate 408. A fixing stud 409 is fixedly installed at the telescopic end of the top end of the electric push rod 407.

[0040] During operation, the drive motor 401 starts and drives the drive turntable 402 to rotate. The edge protrusion drives the linkage bar 403 to reciprocate, so that the linkage turntables 404 at both ends of the linkage bar 403 rotate synchronously. The linkage turntables 404 drive the connecting sleeve 405 to rotate stably under the bearing support of the fixed frame 406, ensuring that the dual-station synchronous operation is without deviation. The electric push rod 407 can drive the fixed stud 409 to extend and retract up and down, realizing the opening or locking of the clamping and fixing mechanism 5.

[0041] As a further embodiment of the present invention, the clamping and fixing mechanism 5 includes a cross mounting bracket 501, which is closely attached to the top of the mounting plate 408. Positioning slots 502 are respectively provided through the two side edges of the bottom of the cross mounting bracket 501. Positioning blocks 411 are symmetrically fixedly installed on the two side edges of the top of the mounting plate 408, and the positioning slots 502 and positioning blocks 411 are correspondingly inserted into each other. Installation through slots 503 are respectively provided inside the two sides of the cross mounting bracket 501 that are perpendicular to each other and the two positioning slots 502. 03. A curved slide rod 504 is symmetrically fixedly installed on the top of the inner wall, and a connecting end plate 505 is fixedly installed on the top of the two curved slide rods 504. L-shaped fixing plates 506 are rotatably installed on the top of the inner walls of the connecting end plate 505 through pins. Fixing slots 412 are respectively provided on the two sides of the top of the mounting plate 408 that are perpendicular to the two positioning blocks 411, and the L-shaped fixing plates 506 are correspondingly engaged with the fixing slots 412. A curved fixing spring 507 is sleeved on the surface of the curved slide rod 504 located on one side of the L-shaped fixing plate 506.

[0042] During operation, the cross mounting bracket 501 is placed close to the top of the mounting plate 408, so that the positioning slot 502 and the positioning block 411 are inserted to achieve radial rapid positioning. Under the rebound action of the arc-shaped fixing spring 507, the L-shaped fixing plate 506 rotates around the pin and is inserted into the fixing slot 412 to form a self-locking fixation. The arc-shaped slide rod 504 and the connecting end plate 505 provide guidance and support for the L-shaped fixing plate 506 to ensure stable engagement and prevent loosening, so as to realize the quick replacement and firm locking of the clamping and fixing mechanism 5.

[0043] As a further embodiment of the present invention, a cross linkage frame 508 is slidably installed through the center of the cross mounting frame 501, and the fixing stud 409 at the top of the electric push rod 407 is correspondingly inserted into the cross linkage frame 508. The fixing stud 409 passes through the top surface of the cross linkage frame 508 and is threadedly connected to a fixing nut 410. Rotary clamping frames 509 are rotatably installed at the four ends of the cross mounting frame 501 through pins, and the end of the rotating clamping frame 509 near the cross linkage frame 508 is slidably connected through a sliding groove to the protrusion surface at the four ends of the cross linkage frame 508. A clamping pin 510 is fixedly installed on the top of the rotating clamping frame 509, and the clamping pin 510 is close to the edge of the optical lens body 6.

[0044] During operation, the electric push rod 407 drives the fixed stud 409 to rise and fall, pushing the cross linkage frame 508 to move up and down. The four protrusions at the four ends of the cross linkage frame 508 drive the four sets of rotating clamping frames 509 to synchronously retract inward or open outward through the sliding groove, so that the clamping pins 510 are evenly attached to the edge of the optical lens body 6, forming a four-point centering clamping, ensuring stable clamping force, small clamping contact area, and uniform force, effectively avoiding scratches and chipping of the edge of the optical lens body 6, and achieving scratch-resistant and reliable clamping.

[0045] As a further embodiment of the present invention, a rectangular mounting groove 801 is provided at the center of one side of the top of the top cover 8, and limiting slide grooves 802 are respectively provided on both sides of the inner wall of the rectangular mounting groove 801. Mounting slide rods 803 are symmetrically fixedly installed inside the rectangular mounting groove 801. A reset moving seat 804 is slidably mounted through the surfaces of the two mounting slide rods 803, and a compression spring 805 is sleeved on the surface of the mounting slide rods 803 on one side of the reset moving seat 804. Moving rollers 806 are symmetrically mounted on both sides of the reset moving seat 804 through a rotating shaft, and the moving rollers 806 are slidably connected inside the limiting slide grooves 802. A guide transmission wheel 807 is rotatably mounted on the top of the reset moving seat 804 through a bearing.

[0046] A rectangular mounting groove 813 is provided at the center of the side of the top cover 8 away from the rectangular mounting groove 801. A grinding motor 808 is fixedly installed inside the rectangular mounting groove 813, and a bevel gear 809 is fixedly installed at the output end of the grinding motor 808. A main drive wheel 810 is rotatably installed at the top edge of the rectangular mounting groove 813 via a bearing. The bottom end of the main drive wheel 810 extends into the rectangular mounting groove 813 and a bevel gear 811 is fixedly installed inside, and the bevel gear 811 meshes with the bevel gear 809. Rectangular through grooves 812 are provided on both sides of the top of the top cover 8, and the rectangular through grooves 812 correspond to the positions of the processing groove 2.

[0047] During operation, as the position of the movable slide plate 901 is adjusted, the compression spring 805 continuously rebounds and pushes the reset movable seat 804, causing it to slide along the mounting slide rod 803. The movable rollers 806 on both sides of the reset movable seat 804 roll within the limiting slide groove 802, reducing friction and ensuring linear motion. The reset movable seat 804 drives the guide transmission wheel 807 to constantly tension the transmission belt 814 outward, ensuring that the transmission belt 814 remains taut during position changes, preventing slippage, loosening, and tooth skipping, thus ensuring stable transmission. The grinding motor 808 starts, driving the first bevel gear 809 to rotate, which meshes with the second bevel gear 811 to reverse the direction and drive the main transmission wheel 810 to rotate. The main transmission wheel 810 transmits power synchronously to the two auxiliary transmission wheels 902 through the transmission belt 814, achieving unified power output from both workstations.

[0048] As a further embodiment of the present invention, the movable grinding mechanism 9 includes a movable slide plate 901, which is slidably connected inside a rectangular through slot 812. A secondary drive wheel 902 is rotatably mounted at the center of the top of the movable slide plate 901 via a bearing. A drive belt 814 is sleeved on the surfaces of the guide drive wheel 807, the main drive wheel 810, and the two secondary drive wheels 902. The bottom end of the secondary drive wheel 902 extends through the movable slide plate 901 and is fixedly mounted on a connecting plate 903 at the bottom of the movable slide plate 901. A fixing toothed ring 904 is fixedly mounted at the center of the bottom of the movable slide plate 901, and the interior of the fixing toothed ring 904 is rotatably connected to the surface of the secondary drive wheel 902 located between the movable slide plate 901 and the connecting plate 903 via a bearing.

[0049] During operation, the transmission belt 814 drives the auxiliary transmission wheel 902 to rotate. The auxiliary transmission wheel 902 drives the connecting plate 903 and the mounting sleeve 905 to revolve around the fixed toothed ring 904. The fixed toothed ring 904 is fixed to the bottom of the movable slide plate 901, providing a central reference for the revolution. The movable slide plate 901 slides in the rectangular through groove 812, and the position of the revolution center can be adjusted so that the grinding disc 908 covers the entire surface of the optical lens body 6 of different diameters, realizing large-range adaptive grinding.

[0050] As a further embodiment of the present invention, a mounting sleeve 905 is fixedly installed at the bottom of the end of the connecting plate 903 away from the auxiliary transmission wheel 902. The two ends inside the mounting sleeve 905 are rotatably mounted with mounting posts 906 through bearings. The top end of the mounting post 906 extends through the mounting sleeve 905 to the top of the mounting sleeve 905 and is fixedly mounted with a drive gear 907, which meshes with a fixed gear ring 904. The bottom end of the mounting post 906 extends through the mounting sleeve 905 to the bottom of the mounting sleeve 905 and is fixedly mounted with a grinding disc 908, which is in close contact with the optical lens body 6.

[0051] During operation, while the mounting sleeve 905 revolves around the fixed gear ring 904, the drive gear 907 continuously meshes with the fixed gear ring 904, driving the mounting column 906 to rotate at high speed within the mounting sleeve 905. The mounting column 906 drives the bottom grinding disc 908 to rotate synchronously, causing the grinding disc 908 to form a composite motion of revolution covering and rotation fine grinding. The composite grinding improves the surface finish and processing efficiency of the optical lens body 6, avoids over-grinding of local areas of the optical lens body 6, and ensures the surface accuracy of the optical lens body 6.

[0052] As a further embodiment of the present invention, the adjusting mechanism 10 includes two electric push rods 1001. The two electric push rods 1001 are fixedly connected to the edges of both sides of the top cover 8. A pusher frame 1002 is fixedly connected to the telescopic end of each electric push rod 1001. Mounting side plates 1003 are symmetrically fixedly installed on both sides of the top of the top cover 8, opposite to the positions of the electric push rods 1001. A rotating crank frame 1004 is rotatably mounted between the two mounting side plates 1003 via a pin. A pusher groove 1005 is provided through the bottom end of the rotating crank frame 1004. The pusher frame 1002 is slidably connected to the inside of the pusher slide 1005. The top two sides of the crank frame 1004 are symmetrically provided with moving slides 1006. The top of the crank frame 1004 is slidably installed with a pusher column 1007, which is slidably connected to the inside of the moving slide 1006. The two pusher columns 1007 are fixedly installed on opposite sides. The bottom of the moving frame 1008 is fixedly connected to the center of the top two sides of the moving slide plate 901. The top of the two moving frames 1008 is fixedly installed with a connecting column 1009.

[0053] During operation, the electric push rod 1001 is extended and retracted according to the specifications of the optical lens body 6, which drives the pusher 1002 to slide in the pusher slide 1005, and drives the rotating crank 1004 to rotate around the pin between the mounting side plates 1003. When the rotating crank 1004 rotates, the pusher 1007 slides in the moving slide 1006, which pushes the moving frame 1008 and the connecting column 1009 to move synchronously, thereby driving the moving slide plate 901 to accurately adjust its lateral position in the rectangular through slot 812 to adapt to the grinding of optical lens bodies 6 of multiple specifications.

[0054] Working principle of this invention:

[0055] First, according to the diameter and thickness specifications of the optical lens body 6 to be processed, a matching clamping and fixing mechanism 5 is selected. The cross mounting bracket 501 is placed stably and tightly on the top of the mounting plate 408 of the grinding rotation mechanism 4, so that the positioning block 411 on the mounting plate 408 is aligned and inserted into the positioning slot 502 at the bottom of the cross mounting bracket 501 to achieve radial rapid positioning and anti-rotation constraint. Under the rebound force of the arc-shaped fixing spring 507, the L-shaped fixing plate 506 is pushed to rotate automatically around the pin shaft and is firmly locked into the fixing slot 412 on the side of the mounting plate 408, forming a spring self-locking fixation, thus completing the rapid and stable assembly of the clamping and fixing mechanism 5 and the mounting plate 408.

[0056] Place the optical lens body 6 stably on top of the cross mounting bracket 501, so that the optical lens body 6 is located in the central area formed by the four clamping pins 510. Activate the electric push rod 407, causing its telescopic end to drive the fixing stud 409 to extend upwards, pushing the cross linkage bracket 508 to rise synchronously. The four protrusions at the four ends of the cross linkage bracket 508 drive the four sets of rotating clamping brackets 509 to synchronously and evenly retract inwards around the pin shaft through the sliding groove, so that the top clamping pin 510 gently and stably fits against the edge of the optical lens body 6, forming a four-point concentric clamping. The fixing nut 410 locks the cross linkage bracket 508 and the fixing stud 409, maintaining a constant clamping force, small contact area, and uniform force distribution, avoiding scratches on the surface of the optical lens body 6 and edge chipping.

[0057] After clamping, the drive motor 401 enters the standby state. When working, the drive motor 401 starts and drives the drive turntable 402 to rotate. Through the edge protrusion and the linkage bar 403, the two linkage turntables 404 at both ends rotate synchronously in the same direction. The linkage turntable 404 drives the top connecting sleeve 405 to rotate stably under the bearing support of the fixed frame 406. This drives the mounting plate 408, the clamping and fixing mechanism 5 and the optical lens body 6 to rotate synchronously and uniformly, providing a stable rotating base for grinding. This ensures that the lens and the grinding plate 908 are evenly attached without eccentricity or wobbling. The electric lifting rods 7 at the four corners of the processing box 1 retract downwards, causing the top cover 8 to descend smoothly. This allows the grinding plate 908 at the bottom of the moving grinding mechanism 9 to gradually approach and gently press against the upper surface of the optical lens body 6. The stroke of the electric lifting rod 7 is precise and controllable, avoiding the impact of the top cover 8 on the optical lens body 6 and ensuring stable initial contact during grinding.

[0058] Based on the grinding range and diameter of the optical lens body 6, the electric push rod 1001 of the adjustment mechanism 10 is extended and retracted, causing the pusher 1002 to slide within the pusher groove 1005 at the bottom of the rotating crank 1004. This drives the rotating crank 1004 to rotate smoothly around the pin between the mounting side plates 1003. The movable groove 1006 at the top of the rotating crank 1004 causes the pusher 1007 to slide, pushing the movable frame 1008 and the connecting column 1009 to move synchronously. This, in turn, causes the movable slide plate 901 to precisely adjust its lateral position within the rectangular through groove 812 of the top cover 8, aligning the grinding disc 908 with the lens to be polished. In the grinding area, to meet the full-surface processing requirements of lenses of different specifications, during the adjustment of the position of the moving slide plate 901, the compression spring 805 continuously rebounds and pushes the reset moving seat 804, causing it to move linearly along the mounting slide rod 803. The moving rollers 806 on both sides of the reset moving seat 804 roll in the limiting slide groove 802. The reset moving seat 804 drives the top guide transmission wheel 807 to always tension the transmission belt 814 outward, so that the transmission belt 814 always remains taut between the main transmission wheel 810, the auxiliary transmission wheel 902 and the guide transmission wheel 807, without slipping, loosening or skipping teeth, ensuring stable and reliable power transmission.

[0059] The grinding motor 808 is started, and its output shaft drives the first bevel gear 809 to rotate, meshing with the second bevel gear 811 and reversing direction, driving the main drive wheel 810 to rotate. The main drive wheel 810 transmits power synchronously to the two auxiliary drive wheels 902 through the transmission belt 814, driving the auxiliary drive wheels 902 to rotate. The auxiliary drive wheels 902 drive the bottom connecting plate 903 and the mounting sleeve 905 to revolve around the fixed gear ring 904, causing the grinding disk 908 to move in a circular trajectory along the surface of the optical lens body 6, achieving full surface coverage. At the same time, during the revolution of the mounting sleeve 905, the top drive gear 907 continuously meshes with the fixed gear ring 904, driving the mounting column 906 to rotate at high speed within the mounting sleeve 905, driving the grinding disk 908 to rotate synchronously. Finally, a composite motion is formed in which the revolution covers the entire lens and the rotation is used for fine grinding, improving the grinding efficiency and surface finish of the optical lens body 6. To improve surface finish, during composite grinding, the grinding rotation mechanism 4 continuously drives the optical lens body 6 to rotate at a uniform speed, creating a speed difference with the movement of the grinding disc 908, further enhancing grinding uniformity. External coolant is sprayed onto the contact area between the optical lens body 6 and the grinding disc 908 to cool down and flush away grinding debris. Waste liquid flows into the processing tank 2 and is discharged in an orderly manner through the drain rack 3, keeping the processing area clean and ensuring continuous and stable processing. After grinding, the grinding motor 808 and drive motor 401 are stopped sequentially, the electric lifting rod 7 is controlled to raise the top cover 8, and the electric push rod 407 is started in the reverse direction, driving the cross linkage frame 508 to descend, causing the rotating clamping frame 509 and the clamping pin 510 to open, releasing the optical lens body 6 and completing the unloading. If it is necessary to change the specifications of the optical lens body 6, the L-shaped fixing plate 506 can be unlocked to quickly change the clamping and fixing mechanism 5 and enter the next batch of processing.
