Description

Technical Field

[0001] This application relates to the field of glass polishing technology, and more specifically, to an optical glass mirror polishing device. Background Technology

[0002] Precision grinding of optical glass lenses is an indispensable core pre-process in the manufacturing process of optical lenses and optical components. Its processing quality directly determines the effect of subsequent polishing processes and the optical performance of the final product. The core function of this process is to remove microscopic protrusion defects on the surface of the glass blank through precise grinding, while correcting the spherical curvature of the lens, so as to provide a substrate with qualified surface condition and high precision for subsequent polishing processes. It is a basic prerequisite for ensuring the imaging quality and optical stability of optical components.

[0003] In actual production and processing scenarios, due to limitations imposed by factors such as production costs, available space, and processing scale, not all production entities have the resources to introduce large-scale precision grinding equipment. Therefore, simple, cost-effective, and easy-to-operate swing-type precision grinding equipment is widely used in small and medium-sized enterprises, research laboratories, and other scenarios primarily involving medium-batch lens processing, becoming the mainstream equipment for precision grinding of optical glass lenses in these environments. This type of equipment has a simple structure, using a rotating base to drive the glass to rotate and a reciprocating grinding head to achieve grinding in conjunction with cutting fluid. For each optical lens, precision grinding requires sequentially changing 2-3 different grit grinding heads, gradually reducing the surface roughness of the lens from coarse to light until it meets the entry standards for subsequent polishing processes.

[0004] The existing simple precision grinding equipment uses a manual disassembly and replacement structure for the grinding head clamping. Each time a single lens needs to be precision ground, 2-3 different grit grinding heads need to be replaced, all of which must be done manually. The process is cumbersome and inefficient. In addition, during the precision grinding process, water-based or oil-based cutting fluid containing diamond abrasive needs to be continuously sprayed to achieve cooling, lubrication and removal of grinding chips. When manually changing the grinding head, it is unavoidable to come into direct contact with the grinding head and the cutting fluid remaining in the processing area. Since this type of cutting fluid contains corrosive components such as alkaline abrasive, organic solvents and rust inhibitors, prolonged exposure can easily cause various occupational health problems such as skin corrosion, allergies and inflammation for operators. This not only fails to meet the relevant requirements for safe production, but also affects the operator's work experience and job stability.

[0005] Therefore, there is an urgent need for an optical glass mirror polishing device that allows for easy replacement of the grinding head. Summary of the Invention

[0012] In some embodiments, each of the switching mechanisms includes: a limiting post disposed at one end of the crossbeam away from the upright; three limiting grooves evenly spaced on the peripheral sidewall of the limiting post, and locking holes formed in one of the limiting grooves near the rotating mechanism, wherein the locking mechanism can be inserted into the locking hole; a mounting plate rotatably sleeved on the limiting post; three limiting blocks evenly spaced on the inner sidewall of the mounting plate and adapted to engage with the three limiting grooves; three through holes respectively formed on the mounting plate and the corresponding limiting block, and coaxially corresponding to the locking hole; and three grinding components evenly spaced and fixedly disposed on the outer sidewall of the mounting plate.

[0013] In some embodiments, each of the grinding components includes: a first support frame, fixedly disposed on the outer wall of the mounting plate; a slide column, disposed on the side of the first support frame away from the mounting plate; a second support frame, disposed at the end of the slide column away from the first support frame, both the first and second support frames having through holes; a control frame, slidably mounted on the slide column, with a handle sleeve fitted on the outer side of the end of the control frame away from the slide column; a guide column, fixedly disposed on the control frame, the guide column being slidable along the through hole on the first support frame; and a pressing column, fixedly disposed at the bottom of the control frame. A first spring is sleeved on the extrusion column, with one end abutting the bottom of the control frame and the other end abutting the top of the second support frame; a ball shaft is rotatably inserted into the through hole of the second support frame; an adjusting joint is disposed at the end of the ball shaft near the extrusion column, abutting the bottom end of the extrusion column, and the first spring is sleeved on the outside of both the extrusion column and the adjusting joint, the size of the adjusting joint being larger than the size of the through hole of the second support frame; a grinding head is disposed at the end of the ball shaft away from the adjusting joint, the side of the grinding head away from the ball shaft having an inwardly concave structure.

[0014] In some embodiments, each of the locking mechanisms includes: a first magnetic block, fixedly disposed at one end of the control frame away from the handle sleeve; a locking pin, passing through the through hole of the first support frame and the mounting plate, and adapted to the locking hole of the limiting post; a second magnetic block, disposed at one end of the locking pin, wherein the first magnetic block and the second magnetic block have opposite magnetic poles; and a second spring, sleeved on the locking pin, wherein one end of the second spring abuts against the second magnetic block and the other end abuts against the first support frame.

[0018] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects: The optical glass mirror polishing equipment provided in this application can realize the rapid rotational switching of three polishing heads with different grit sizes through a switching mechanism, eliminating the need for manual disassembly and assembly of the polishing heads in sequence, thus improving processing efficiency. The operator places the optical glass lens to be polished stably on the rotating mechanism's bearing surface at any polishing station, selects the corresponding grit polishing head, aligns it with the polishing station, and the locking mechanism automatically locks the initial position. The rotating mechanism drives the lens to be polished to rotate at a uniform speed, and the oscillating mechanism drives the switching mechanism and the corresponding grit polishing head to oscillate back and forth. Simultaneously, the corresponding coolant nozzles spray coolant precisely onto the polishing area to assist the polishing process. Under the synergistic effect of its own oscillation and the uniform rotation of the lens, the polishing head polishes the lens surface, completing the polishing process corresponding to that grit. After the polishing process of the current grit is completed, the operator lifts the switching mechanism upward and rotates it, the locking mechanism automatically unlocks, and rotates another polishing component of a different grit to the station position, aligning the polishing head of that grit with the lens polishing surface. The locking mechanism then locks the relative position of the polishing component again. According to the polishing requirements of the lens, the above precision switching steps are repeated. By rotating the switching mechanism once, three different grit polishing components are switched, gradually realizing the polishing of the lens at different precision stages until the lens is polished to the required state. The switching mechanism enables rapid rotational switching between three grinding heads of different grit sizes, eliminating the need for manual disassembly and assembly of the grinding heads one by one. This solves the problem of low grinding head replacement efficiency in existing equipment, shortens the grinding cycle of a single lens, and further improves processing efficiency.

[0022] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0024] The following reference Figures 1 to 11 This application describes an optical glass mirror polishing apparatus provided according to some embodiments.

[0025] like Figure 1 , Figure 2 As shown, the optical glass mirror polishing equipment provided according to some embodiments of this application includes an equipment housing 110, a rotating mechanism 200, a swinging mechanism 300, a switching mechanism 400, and a locking mechanism 500. The equipment housing 110 is equipped with three independent polishing stations, and each polishing station is equipped with a coolant nozzle 140. The coolant nozzle 140 is used to precisely spray coolant onto the corresponding polishing station. Each polishing station includes: a rotating mechanism 200, which is disposed on the bottom wall of the equipment housing 110; the optical glass lens to be polished is placed on the top bearing surface of the rotating mechanism 200; the rotating mechanism 200 can drive the optical glass lens to rotate at a uniform speed, providing stable rotational motion for lens polishing; a swinging mechanism 300, which is disposed on the side wall of the equipment housing 110, and can realize reciprocating swinging; and a switching mechanism. 400 is located at the end of the swing mechanism 300 away from the equipment box 110. The switching mechanism 400 includes three independent grinding components. The three grinding components are respectively equipped with grinding heads 490 of different grit sizes. The three grinding components can rotate and switch around the end of the swing mechanism 300. After switching, the end grinding head 490 of the corresponding grinding component can make precise contact with the optical glass lens on the rotating mechanism 200 to achieve grinding operations at different precision stages. The locking mechanism 500 is located on the switching mechanism 400 and is used to quickly lock the relative position of any grinding component after it is switched to the working position.

[0026] In this embodiment, the operator places the optical glass lens to be polished stably on the bearing surface of the rotating mechanism 200 at any polishing station, selects the polishing head 490 of the corresponding grit size, aligns it with the polishing station, and the locking mechanism 500 automatically locks the initial position. The rotating mechanism 200 drives the lens to be polished to rotate at a constant speed, and the swing mechanism 300 drives the switching mechanism 400 and the polishing head 490 of the corresponding grit size to swing back and forth. At the same time, the corresponding coolant nozzle 140 synchronously and precisely sprays coolant into the polishing area to assist the polishing process. Under the synergistic effect of its own reciprocating swing and the uniform rotation of the lens, the polishing head 490 aligns with the lens... The lens surface is polished to complete the polishing process corresponding to the current grit size. After the polishing process of the current grit size is completed, the operator lifts the switching mechanism 400 upward and rotates it. The locking mechanism 500 automatically unlocks, and another polishing component of a different grit size is rotated to the work position so that the polishing head 490 of that grit size is aligned with the lens polishing surface. The locking mechanism 500 locks the relative position of the polishing component again. According to the lens polishing requirements, the above precision switching steps are repeated. By rotating the switching mechanism 400 once, three polishing components of different grit sizes are switched, and the polishing of the lens at different precision stages is gradually realized until the lens is polished to the required state.

[0027] In this design, the switching mechanism 400 enables rapid rotational switching of three grinding heads 490 with different grit sizes, eliminating the need for manual disassembly and assembly of the grinding heads one by one. This solves the problem of low grinding head replacement efficiency in existing equipment, shortens the grinding cycle of a single lens, and further improves processing efficiency.

[0028] In some possible embodiments, such as Figure 2 , Figure 3 As shown, it also includes: a grinding pool 120, which is sealed on the equipment box 110; a control box 130, which is located on the top of the equipment box 110; three grinding stations are evenly spaced on the grinding pool 120, and three coolant nozzles 140 are respectively adapted and installed to the corresponding grinding stations.

[0029] In this embodiment, the grinding tank 120 serves as the carrier for grinding operations within the equipment. It is installed in a sealed structure on the equipment box 110, effectively preventing leakage of waste coolant and glass shavings during grinding, thus protecting the surrounding environment and ensuring the cleanliness of the work area. The control box 130 coordinates the operation of various mechanisms within the equipment, including the start / stop and speed adjustment of the rotating mechanism 200, the reciprocating oscillation frequency control of the swing mechanism 300, and the start / stop and spray volume adjustment of the coolant nozzle 140. The three independent grinding stations are evenly spaced to ensure each station has sufficient working space, preventing interference between multiple stations operating simultaneously.

[0030] In some possible embodiments, such as Figure 2 , Figure 3As shown, each rotating mechanism 200 includes: a rotating shaft 210, which is disposed on the grinding tank 120, and a power component is connected to the bottom end of the rotating shaft 210; a placement platform 220, which is disposed on the top end of the rotating shaft 210; and an isolation cover 230, which is a sealing cover disposed on the outside of the rotating shaft 210 and the power component.

[0031] In this embodiment, the optical glass lens to be polished is placed on the top surface of the placement platform 220. The operating parameters of the power component are preset by the control box 130, and the power component outputs stable power to drive the rotating shaft 210 connected to it to rotate at a constant speed. The placement platform 220 at the top rotates synchronously, and the lens to be polished on the placement platform 220 rotates at a constant speed together with the placement platform 220. During the uniform rotation of the lens, the swing mechanism 300 corresponding to the polishing station drives the polishing head 490 of the switching mechanism 400 to swing back and forth. The polishing head 490 contacts the rotating lens to carry out the polishing operation. The coolant nozzle 140 sprays coolant precisely into the polishing area. At this time, the isolation cover 230 plays a sealing and protective role, preventing coolant and polishing debris from entering the connection between the rotating shaft 210 and the power component, ensuring that the rotating shaft 210 rotates continuously and stably.

[0032] In some possible embodiments, such as Figures 2 to 4 As shown, each swing mechanism 300 includes: a swing shaft 310, which is rotatably mounted on the side wall of the polishing tank 120; a vertical frame 320, which is fixedly connected to the swing shaft 310; and a horizontal frame 330, which is disposed at one end of the vertical frame 320 near the placement table 220.

[0033] In this embodiment, the swing shaft 310 swings back and forth, synchronously driving the upright frame 320 to swing back and forth. The upright frame 320 then drives the horizontal frame 330 at its end to swing back and forth synchronously. The switching mechanism 400 and the polishing assembly fixed on the horizontal frame 330 swing back and forth together with the horizontal frame 330. While the swing mechanism 300 drives the polishing head 490 to swing back and forth, the rotation mechanism 200 of the corresponding workstation drives the lens to be polished on the placement table 220 to rotate at a uniform speed. The polishing head 490 makes precise contact with the rotating lens, forming a coordinated polishing mode of lens rotation and polishing head 490 swinging back and forth, ensuring that every area of ​​the lens surface can be evenly covered by the polishing head 490.

[0034] In some possible embodiments, such as Figures 4 to 10As shown, each switching mechanism 400 includes: a limiting post 410, disposed at the end of the crossbeam 330 away from the upright 320; three limiting grooves 411, evenly spaced on the peripheral wall of the limiting post 410; and locking holes 412, each located in a limiting groove 411 near the rotating mechanism 200, into which the locking mechanism 500 can be inserted; a mounting plate 420, rotatably sleeved on the limiting post 410; and three limiting blocks 421, evenly spaced on the inner wall of the mounting plate 420, which are adapted to engage with the three limiting grooves 411. Three through holes 422 are respectively opened on the mounting plate 420 and the corresponding limiting block 421, and are coaxially and correspondingly adapted to the locking hole 412; three grinding components are evenly spaced and fixedly arranged on the outer side wall of the mounting plate 420; each grinding component includes: a first support frame 430, fixedly arranged on the outer side wall of the mounting plate 420; a sliding column 440, arranged on the side of the first support frame 430 away from the mounting plate 420; a second support frame 450, arranged at the end of the sliding column 440 away from the first support frame 430, the first support frame 430 and the second support frame 450 are connected. Each support frame 450 has a through hole; a control frame 460 is slidably mounted on a sliding column 440, and a handle sleeve is fitted on the outer side of the end of the control frame 460 away from the sliding column 440; a guide column 461 is fixedly mounted on the control frame 460 and can slide along the through hole on the first support frame 430; a pressing column 462 is fixedly mounted on the bottom of the control frame 460; a first spring 470 is fitted on the pressing column 462, with one end of the first spring 470 abutting against the bottom of the control frame 460 and the other end abutting against the top of the second support frame 450. Connect; ball shaft 480, rotatably inserted into the through hole of the second support frame 450; adjusting joint 481, located at the end of the ball shaft 480 near the extrusion column 462, the adjusting joint 481 abuts against the bottom end of the extrusion column 462, the first spring 470 is sleeved on the outside of both the extrusion column 462 and the adjusting joint 481, the size of the adjusting joint 481 is larger than the size of the through hole of the second support frame 450; grinding head 490, located at the end of the ball shaft 480 away from the adjusting joint 481, the side of the grinding head 490 away from the ball shaft 480 has a concave structure.

[0035] In this embodiment, in the initial state, the mounting plate 420 is fitted onto the limiting post 410, and one of the limiting blocks 421 is engaged in the limiting groove 411 near the rotating mechanism 200. The through holes 422 on the mounting plate 420 and the corresponding limiting block 421 are aligned with the locking holes 412 in the limiting groove 411. The locking mechanism 500 automatically inserts into the locking hole 412, and the position of the mounting plate 420 is locked. At this time, the control frame 460 is in the lowest position under its own weight and the natural elastic force of the first spring 470. The grinding head 490 is in contact with the lens on the rotating mechanism 200, and the top wall of the adjusting joint 481 is in contact with the bottom wall of the extrusion post 462. The current grit grinding process is completed. When it is necessary to switch to another different grit grinding head 490, the operator holds the current grinding head 490 in hand. When the handle sleeve of the grinding assembly is lifted, the control frame 460 is raised. At this time, the control frame 460 slides upward along the slide column 440, and the guide column 461 slides upward along the through hole on the first support frame 430 until the top wall of the control frame 460 is tightly fitted with the bottom wall of the first support frame 430. The handle sleeve is then lifted further upward. Because the control frame 460 is in contact with the first support frame 430, the force is transmitted to the second support frame 450, causing the second support frame 450 to slide upward along the ball joint 480 until the top wall of the second support frame 450 is tightly fitted with the bottom wall of the adjusting joint 481. At this time, the pressing column 462 continues to move upward with the control frame 460, and the first spring 470 is compressed by the pressing column 462 and the second support frame 450, and is in a compressed state. The control frame 460 and locking mechanism 500 are aligned, triggering the locking mechanism 500 to unlock. The control frame 460 continues to rise, causing the first support frame 430 to move upward. Simultaneously, the first support frame 430 drives the second support frame 450, adjusting connector 481, and mounting plate 420 to slide upward along the limiting post 410. The limiting block 421 inside the mounting plate 420 disengages from the currently engaged limiting groove 411, releasing the rotational restriction of the mounting plate 420 by the limiting post 410. Maintaining the upward-lifted state of the mounting plate 420, the control frame 460 is rotated, causing the first support frame 430 and mounting plate 420 to rotate synchronously around the limiting post 410 until the next grit grinding component aligns with the limiting groove 411 of the grinding station. At this point, the operation... When the external force applied to the control frame 460 is released, the mounting plate 420 slides downward along the limiting post 410 under its own weight. At this time, the first spring 470 returns to its elastic deformation, pushing the second support frame 450 to slide downward along the ball joint 480, disengaging from its contact with the adjusting joint 481. Simultaneously, it pushes the control frame 460 to slide downward along the sliding post 440. The guide post 461 extends downward along the through hole on the first support frame 430. The first spring 470 returns to its natural state. The newly switched grinding head 490 is precisely aligned with the lens at the grinding station. After the control frame 460 of the newly switched grinding assembly returns to its initial state, the control frame 460 and the locking mechanism 500 are misaligned. The locking mechanism 500 automatically inserts into the through hole 422 on the mounting plate 420 and the limiting block 421.The grinding head 490 extends into the locking hole 412 of the limiting groove 411 to relock the relative position of the mounting plate 420, preventing displacement after switching. The grinding head 490 then completes the switching process, and the new grit grinding head 490 makes precise contact with the lens to perform the corresponding precision grinding operation. This switching process is repeated, sequentially switching the three different grit grinding head 490 assemblies to complete the full precision grinding process from coarse to fine grinding of the lens until the lens is polished to the required level.

[0036] In some possible embodiments, such as Figure 11 As shown, each locking mechanism 500 includes: a first magnetic block 510, fixedly disposed at the end of the control frame 460 away from the handle sleeve; a locking pin 520, passing through the through hole 422 of the first support frame 430 and the mounting plate 420, and adapted to the locking hole 412 of the limit post 410; a second magnetic block 530, disposed at one end of the locking pin 520, the first magnetic block 510 and the second magnetic block 530 having opposite magnetic poles; and a second spring 540, sleeved on the locking pin 520, one end of the second spring 540 abutting against the second magnetic block 530, and the other end abutting against the first support frame 430.

[0037] In this embodiment, during the grinding state, the control frame 460 is in its lowest initial position under its own weight and the natural elastic force of the first spring 470. The first magnetic block 510 and the second magnetic block 530 fixed on the control frame 460 are misaligned and have no magnetic attraction. The second spring 540 is in its natural state and continuously applies elastic force to the second magnetic block 530 in the direction of the locking hole 412. The locking pin 520 is inserted into the locking hole 412, and the mounting plate 420 is limited by the locking pin 520, the limiting block 421, and the limiting groove 411, preventing it from rotating or sliding up and down. The grinding process is then switched. During the head 490 process, the control frame 460 slides upward, and the first magnetic block 510 gradually approaches the second magnetic block 530. The two generate a magnetic attraction force, which is greater than the elastic force of the second spring 540. This pulls the second magnetic block 530 towards the first magnetic block 510. The locking pin 520 slides along the through hole 422 until its end disengages from the locking hole 412 of the limit post 410 and the through hole 422 of the mounting plate 420, releasing the locking restriction on the mounting plate 420. At this time, the operator can continue to lift the control frame 460 upward and rotate it to switch the grinding head 490.

[0038] In some possible embodiments, such as Figure 2 As shown, the central curvature of the optical glass lens placed on the placement stage 220 is exactly opposite to the center of the swing axis 310.

[0039] In this embodiment, the center of the lens and the center of curvature are aligned with the center of the swing axis 310. When the grinding head 490 swings back and forth with the swing axis 310, its motion trajectory can evenly cover the entire curved surface of the lens. During the uniform rotation of the lens around its own geometric center, the contact distance and contact pressure between each point on the surface and the grinding head 490 remain consistent. This can completely avoid problems such as over-grinding, ungrinding, and uneven surface roughness of the lens caused by positioning offset, greatly improving the lens processing qualification rate and reducing waste.

[0040] In some possible embodiments, such as Figure 10 As shown, the ball shaft 480 and the adjusting connector 481 are connected by a detachable thread.

[0041] In this embodiment, during the grinding operation, the ball shaft 480 needs to rotate at multiple angles and transmit force for a long time, which is prone to wear, jamming and other failures; the adjusting joint 481 needs to be in contact with the extrusion column 462 for a long time and bear the spring force and extrusion force, which may also cause wear and deformation. Since the two are connected by a detachable thread, it is not necessary to disassemble the entire grinding assembly. Only the ball shaft 480 or the adjusting joint 481 needs to be rotated to separate them. The worn or faulty ball shaft 480 or adjusting joint 481 can be quickly replaced or repaired individually, which greatly reduces the difficulty of maintenance and saves maintenance time.

[0042] In some possible embodiments, such as Figure 3 As shown, the placement platform 220 and the rotation axis 210, as well as the corresponding extrusion column 462 and the corresponding ball axis 480, are all on the same central axis.

[0043] In this embodiment, the integrated coaxial structure ensures that the lens rotation trajectory and the force state of the grinding head 490 are consistent at the grinding station, avoiding differences in lens processing accuracy caused by coaxial deviation of components. It is also suitable for multi-station synchronous operation scenarios, which can greatly improve the processing consistency of batch lenses, reduce waste and improve production efficiency.

[0044] When the optical glass mirror polishing equipment is in operation, the operator places the optical glass lens to be polished stably on the placement platform 220 of the rotating mechanism 200 at any polishing station. The operating parameters of each mechanism are preset through the control box 130 on top of the equipment box 110. The switching mechanism 400 is initially positioned, with the polishing head 490 of one of the polishing components aligned with the lens. The locking mechanism 500 automatically inserts into the locking hole 412, completing the initial locking of the mounting plate 420 and the polishing components. The coolant nozzle 140 is precisely matched to the corresponding station. After the equipment is started, the power component of the rotating mechanism 200 outputs stable power, driving the rotating shaft 210 to rotate at a uniform speed, causing the placement platform 220 on top and the lens to rotate synchronously and coaxially. The swing mechanism 3... The oscillating shaft 310 of the 00 reciprocates, driving the upright frame 320, the horizontal frame 330, the switching mechanism 400, and the grinding assembly to reciprocate synchronously, ensuring that the grinding head 490 makes precise contact with the rotating lens. Simultaneously, the coolant nozzle 140 at the corresponding workstation sprays coolant into the grinding area to assist grinding. The isolation cover 230 seals and protects the rotating shaft 210 and the power assembly, preventing coolant and grinding debris from entering. Under the combined effect of its own reciprocating oscillation and the uniform rotation of the lens, the grinding head 490 completes the grinding process corresponding to the current grit size. After grinding the current grit size, the operator holds the handle sleeve of the corresponding grinding assembly and lifts the control frame 460 upwards. The control frame 460 slides along the sliding column 440, and the guide column 461 simultaneously slides along the first support frame 4... The control frame 460 slides through the through hole until it is in contact with the first support frame 430. It continues to rise, transmitting force to the second support frame 450, causing it to slide along the ball joint 480 and engage with the adjusting joint 481. The first spring 470 is compressed. At this point, the control frame 460 aligns with the locking mechanism 500. The first magnet 510 and the second magnet 530 generate magnetic attraction, overcoming the elastic force of the second spring 540 and pulling the locking pin 520 out of the locking hole 412 and through hole 422, releasing the lock on the mounting plate 420. The control frame 460 continues to rise, causing the first support frame 430, the second support frame 450, and the mounting plate 420 to slide upwards along the limiting post 410, causing the limiting block 421 to disengage from the limiting groove 411. The control frame 460 is then rotated. The mounting plate 420 is used to align the next grit grinding component with the grinding station. The external force on the control frame 460 is removed, and the mounting plate 420 slides down under its own weight. The limit block 421 is engaged in the corresponding limit groove 411, the first spring 470 is reset, and the control frame 460 and the second support frame 450 are pushed down to the initial position. The newly switched grinding head 490 is aligned with the lens. The control frame 460 and the locking mechanism 500 are misaligned. The second spring 540 pushes the locking pin 520 to insert into the through hole 422 and the locking hole 412, and the mounting plate 420 is locked again, completing the switching of the grinding head 490. The above grinding head 490 switching process is repeated to switch the three different grit grinding components in sequence, gradually completing the full precision grinding process of the lens from coarse grinding to fine grinding.
