Description

Technical Field

[0001] This utility model relates to the field of lens processing equipment technology, specifically a vertical lens edging machine. Background Technology

[0002] Current lens edging machines are generally horizontal, using two horizontally extending clamps to hold the lens and then grinding it. However, when held by the clamps, the lens, lacking support underneath, tends to shift downwards under gravity. For larger and heavier lenses, this downward shift during clamping can alter the lens's position, changing the edging area and resulting in substandard edging. Therefore, horizontal edging machines are unsuitable for edging larger and heavier lenses. Utility Model Content

[0003] The purpose of this invention is to provide a vertical lens edging machine to solve the problem that existing lens edging machines, which are horizontal, are not suitable for edging larger and heavier lenses.

[0004] To solve the above problems, the present invention provides the following technical solution:

[0016] As described above, a vertical lens edging machine includes a pick-and-place device comprising a tray support fixedly disposed between the storage compartment and the edging station, a pick-and-place arm movably disposed between the storage compartment and the edging station, and a pick-and-place drive component connected to the pick-and-place arm to drive the pick-and-place arm to move. The pick-and-place arm can be connected to the lens tray to move the lens tray from the storage compartment to the tray support and / or move the lens tray from the tray support to the storage compartment.

[0017] As described above, in a vertical lens edging machine, the tray support has a tray channel extending from the storage compartment to the edging station. The storage compartment includes a storage rack and a lifting assembly. Several lens trays are spaced apart from top to bottom on the storage rack. The lifting assembly is connected to the storage rack to drive the storage rack to rise and fall. When the lifting assembly drives the storage rack to rise and fall until one of the lens trays is level with the tray channel, the pick-and-place arm is connected to the lens tray to move the lens tray from the storage rack to the tray channel and / or move the lens tray from the tray channel to the storage rack.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This utility model provides a vertical lens edging machine. A clamping drive mechanism drives a first clamp to approach a second clamp to hold the lens. Then, a first rotary drive mechanism drives the first clamp to rotate, and a second rotary drive mechanism drives the second clamp to rotate, thereby rotating the lens. Simultaneously, an edging drive mechanism drives a grinding disc to rotate, thus edging the lens. Since the first and second clamps are coaxially arranged opposite each other in the vertical direction, when the lens is held by the first and second clamps, the second clamp provides support for the lens from below, effectively preventing the lens from shifting due to gravity. This design is suitable for edging large and heavy lenses. Attached Figure Description

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

[0036] Please see Figures 1 to 12 This embodiment provides a vertical lens edging machine, including a frame 6, on which an edging station 9 is provided. The edging station 9 is provided with a clamping device 4 and an edging device 5. The clamping device 4 includes a first clamp 41, a second clamp 42, a first rotary drive mechanism 43, a second rotary drive mechanism 44, and a clamping drive mechanism 45. The first clamp 41 and the second clamp 42 are coaxially opposite each other in the vertical direction. The first rotary drive mechanism 43 is connected to the first clamp 41 to drive the first clamp 41 to rotate. The second rotary drive mechanism 44 is connected to the second clamp 42 to drive the second clamp 42 to rotate. The clamping drive mechanism 45 is connected to the first clamp 41 to drive the first clamp 41 to move closer to or away from the second clamp 42. The edge grinding device 5 includes a grinding disc 51 and an edge grinding drive mechanism 52. The edge grinding drive mechanism 52 is connected to the grinding disc 51 to drive the grinding disc 51 to rotate. The rotation axis of the grinding disc 51 is parallel to the rotation axis of the first clamp 41 and the rotation axis of the second clamp 42.

[0037] This embodiment of a vertical lens edging machine uses a clamping drive mechanism 45 to drive a first clamp 41 to approach a second clamp 42 to clamp the lens. Then, a first rotation drive mechanism 43 drives the first clamp 41 to rotate, and a second rotation drive mechanism 44 drives the second clamp 42 to rotate, thereby rotating the lens. Simultaneously, an edging drive mechanism 52 drives a grinding disc 51 to rotate, thus edging the lens. Since the first clamp 41 and the second clamp 42 are coaxially opposite each other in the vertical direction, when the lens is clamped by the first clamp 41 and the second clamp 42, the second clamp 42 provides support for the lens from below, effectively preventing the lens from shifting due to gravity. This design is suitable for edging large and heavy lenses.

[0038] Furthermore, the frame 6 is provided with a first guide channel 601 and a second guide channel 602, which extend coaxially in the vertical direction; the first rotary drive mechanism 43 includes a first rotary drive member 431, a first rotating shaft 432, and a first bushing 433, the first bushing 433 being disposed in the first guide channel 601, the first rotating shaft 432 being rotatably disposed in the first bushing 433, one end of the first rotating shaft 432 being connected to the first clamp 41, and the other end being connected to the first rotary drive member 431; the second rotary drive mechanism 44 includes a second rotary drive member 441, a second rotating shaft 442, and a second bushing 443, the second bushing 443 being disposed in the second guide channel 602, the second rotating shaft 442 being rotatably disposed in the second bushing 443, one end of the second rotating shaft 442 being connected to the second clamp 42, and the other end being connected to the second rotary drive member 441. The first rotary drive 431 drives the first rotating shaft 432 to rotate relative to the first bushing 433, thereby causing the first clamp 41 to rotate. A first rolling bearing 434 is provided between the first rotating shaft 432 and the first bushing 433, so that when the first rotating shaft 432 rotates, the first bushing 433 does not rotate synchronously. Similarly, the second rotary drive 441 drives the second rotating shaft 442 to rotate relative to the second bushing 443, thereby causing the second clamp 42 to rotate. A second rolling bearing 444 is provided between the second rotating shaft 442 and the second bushing 443, so that when the second rotating shaft 442 rotates, the second bushing 443 does not rotate synchronously. Furthermore, the first guide channel 601 and the second guide channel 602 enable the positioning and installation of the first bushing 433 and the second bushing 443, thereby enabling the positioning and installation of the first rotating shaft 432 and the second rotating shaft 442, and consequently, the positioning and installation of the first clamp 41 and the second clamp 42, improving the accuracy of the fit between the first clamp 41 and the second clamp 42. Preferably, both the first rotary drive member 431 and the second rotary drive member 441 are servo motors.

[0039] Further, the clamping drive mechanism 45 includes a clamping drive member 451 and a clamping drive seat 452. The clamping drive seat 452 is connected to the first rotary drive member 431 and the first bushing 433. The clamping drive member 451 is located above and connected to the clamping drive seat 452, so as to drive the clamping drive seat 452 to move the first rotary drive mechanism 43, thereby causing the first clamp 41 to move closer to or away from the second clamp 42. When the clamping drive member 451 drives the clamping drive seat 452 to move downward in the vertical direction, it drives the first rotary drive member 431 and the first bushing 433 to move downward synchronously, thereby causing the first clamp 41 to move closer to the second clamp 42 to clamp the lens. When the clamping drive member 451 drives the clamping drive seat 452 to move upward in the vertical direction, it drives the first rotary drive member 431 and the first bushing 433 to move upward synchronously, thereby causing the first clamp 41 to move away from the second clamp 42 to release the lens. The clamping drive base 452 connects both the first rotary drive component 431 and the first bushing 433, which facilitates the synchronous movement of the first rotary drive component 431 and the first bushing 433, and also helps to ensure that the relative positions of the first rotary drive component 431 and the first bushing 433 remain unchanged, thereby ensuring a stable connection between the first rotary drive component 431 and the first rotating shaft 432. Preferably, the clamping drive component 451 is a cylinder or hydraulic cylinder, with its fixed end connected to the frame 6 and its telescopic end connected to the clamping drive base 452.

[0040] Furthermore, the clamping device 4 also includes a clamping guide mechanism 46, which includes a clamping guide rail 461 and a clamping slider 462. The clamping guide rail 461 extends vertically on the frame 6, and the clamping slider 462 is connected to the clamping drive seat 452 and slidably mounted on the clamping guide rail 461. When the clamping drive member 451 drives the clamping drive seat 452 to move vertically, the clamping slider 462 connected to the clamping drive seat 452 moves along the clamping guide rail 461, providing directional guidance for the movement of the clamping drive seat 452 and making the movement of the clamping drive seat 452 more stable.

[0041] Furthermore, the frame 6 is provided with a buffer 604, and the clamping drive seat 452 is provided with a buffer plate 4521. When the clamping drive member 451 drives the clamping drive seat 452 to move downward in the vertical direction until the buffer plate 4521 contacts the buffer 604, the buffer 604 provides a buffering effect for the clamping drive seat 452, thereby providing a buffering effect for the first rotary drive member 431, the first rotating shaft 432, the first bushing 433, and the first clamp 41.

[0042] Furthermore, the edging device 5 also includes an edging lateral movement mechanism 53 and an edging lifting mechanism 54. The edging lateral movement mechanism 53 is connected to the edging drive mechanism 52 to drive the edging drive mechanism 52 to move, thereby causing the grinding disc 51 to move closer to or further away from the first clamp 41 and the second clamp 42. The edging lifting mechanism 54 is connected to the edging lateral movement mechanism 53 to drive the edging lateral movement mechanism 53 to drive the edging drive mechanism 52 to move, thereby causing the grinding disc 51 to rise or fall. The edging lateral movement mechanism 53 can effectively adjust the distance between the grinding disc 51 and the first clamp 41 and the second clamp 42 to suit edging lenses of different sizes. The edging lifting mechanism 54 can effectively adjust the relative height between the grinding disc 51 and the first clamp 41 and the second clamp 42 to suit edging lenses of different thicknesses.

[0043] Further, the edge grinding lifting mechanism 54 includes an edge grinding lifting drive 541, an edge grinding lifting guide rail 542, and an edge grinding lifting slide 543. The edge grinding lifting guide rail 542 extends vertically on the frame 6, and the edge grinding lifting slide 543 is slidably mounted on the edge grinding lifting guide rail 542. The edge grinding lifting drive 541 is connected to the edge grinding lifting slide 543 to drive the edge grinding lifting slide 543 to move along the edge grinding lifting guide rail 542. The edge grinding transverse movement mechanism 53 includes a grinding wheel... The system comprises a lateral movement drive 531, a lateral movement guide rail 532, and a lateral movement slide 533. The lateral movement guide rail 532 extends horizontally and is mounted on the lateral movement lifting slide 543. The lateral movement slide 533 is slidably mounted on the lateral movement guide rail 532 and is connected to the lateral movement drive mechanism 52. The lateral movement drive 531 is connected to the lateral movement slide 533 to drive the lateral movement slide 533 to move along the lateral movement guide rail 532. When the lateral movement drive 531 drives the lateral movement slide 533 to move horizontally along the lateral movement guide rail 532, it drives the lateral movement drive mechanism 52 to move horizontally, thereby causing the grinding disc 51 to move closer to or away from the first clamp 41 and the second clamp 42. When the grinding edge lifting drive unit 541 drives the grinding edge lifting slide 543 to move along the grinding edge lifting guide rail 542, it drives the grinding edge lateral movement mechanism 53 to move in the vertical direction, thereby driving the grinding edge drive mechanism 52 to move in the vertical direction, and then driving the grinding disc 51 to rise and fall. The grinding edge lifting drive unit 541 includes a grinding edge lifting servo motor, a grinding edge lifting screw connected to the output end of the grinding edge lifting servo motor, and a grinding edge lifting nut threaded with the grinding edge lifting screw. The grinding edge lifting nut is connected to the grinding edge lifting slide 543. When the grinding edge lifting servo motor drives the grinding edge lifting screw to rotate, the grinding edge lifting nut drives the grinding edge lifting slide 543 to move along the grinding edge lifting guide rail 542. Similarly, the grinding lateral movement drive 531 includes a grinding lateral movement servo motor, a grinding lateral movement lifting screw connected to the output end of the grinding lateral movement servo motor, and a grinding lateral movement nut threadedly engaged with the grinding lateral movement lifting screw. The grinding lateral movement nut is connected to the grinding lateral movement slide 533. When the grinding lateral movement servo motor drives the grinding lateral movement lifting screw to rotate, the grinding lateral movement nut drives the grinding lateral movement slide 533 to move along the grinding lateral movement guide rail 532.

[0044] Furthermore, a protective assembly 7 is provided on the edge grinding station. The protective assembly 7 includes a protective body 71, a protective baffle 72, and a baffle drive 73. The protective body 71 and the frame 6 form an edge grinding working cavity 711. A feed port 712 communicating with the edge grinding working cavity 711 is provided on one side of the protective body 71. The protective baffle 72 is movably disposed on one side of the feed port 712. The baffle drive 73 is connected to the protective baffle 72 to drive the protective baffle 72 to move to close or open the feed port 712. Preferably, the baffle drive 73 is a cylinder or hydraulic cylinder, with its fixed end connected to the frame 6 and its telescopic end connected to the protective baffle 72. When the baffle drive 73 drives the protective baffle 72 to open the feed port 712, it facilitates the lens to enter the grinding working cavity 711 and cooperate with the first clamp 41 and the second clamp 42; when the baffle drive 73 drives the protective baffle 72 to close the feed port 712, it effectively avoids isolating external interference.

[0045] Furthermore, the upper end face of the protective body 71 is provided with a first through hole 713 and a second through hole 714 communicating with the grinding working cavity 711. The grinding disc 51 passes through the first through hole 713 and enters the grinding working cavity 711, and the first clamp 41 passes through the second through hole 714 and enters the grinding working cavity 711.

[0046] Furthermore, the protective body 71 includes a first protective cover 7101 and a second protective cover 7102, which are detachably connected. When it is necessary to inspect the first clamp 41, the second clamp 42, and the grinding disc 51, the first protective cover 7101 can be removed for inspection.

[0047] The edging device 5 also includes a spraying mechanism 55, which includes a nozzle located on one side of the grinding disc 51. The frame 6 has a water outlet 603 communicating with the edging working chamber 711. The spraying mechanism 55 can spray lubricating oil onto the grinding disc 51 and the lens edging area to achieve a better edging effect. Furthermore, the sprayed lubricating oil can be discharged through the water outlet 603 or collected and treated uniformly, preventing the accumulation of lubricating oil in the edging working chamber 711.

[0048] Furthermore, the vertical lens edging machine also includes a storage compartment 1, a pick-and-place device 2, and a transfer device 3. The storage compartment 1 is provided with a plurality of lens trays 13. The pick-and-place device 2 is used to remove the lens trays 13 from the storage compartment 1 and / or place the lens trays 13 into the storage compartment 1. The transfer device 3 is used to transfer the lens from the lens trays 13 to the edging station and / or transfer the lens from the edging station to the lens trays 13. Storage compartment 1 can store multiple lens trays 13. During the loading process of the grinding station 9, the lens trays 13 can be moved out of storage compartment 1 by the pick-and-place device 2, and then the lens 14 can be transferred from the lens trays 13 to the grinding station 9 by the transfer device 3. After processing is completed, the lens 14 can be transferred from the grinding station 9 to the lens trays 13 by the transfer device 3, and then the lens trays 13 can be placed into storage compartment 1 by the pick-and-place device 2. No special personnel need to be stationed there, which can effectively reduce labor costs, save time and effort, and has a high degree of automation.

[0049] Furthermore, the pick-and-place device 2 includes a tray support 21 fixedly disposed between the storage compartment 1 and the edging station, a pick-and-place arm 22 movably disposed between the storage compartment 1 and the edging station, and a pick-and-place drive component 23 connected to the pick-and-place arm 22 to drive the pick-and-place arm 22 to move. The pick-and-place arm 22 can be connected to the lens tray 13 to drive the lens tray 13 from the storage compartment 1 to the tray support 21 and / or drive the lens tray 13 from the tray support 21 to the storage compartment 1. After the pick-and-place drive component 23 drives the pick-and-place arm 22 to remove the lens tray 13 from the storage compartment 1, the lens tray 13 can be temporarily and stably placed on the tray support 21 for loading and unloading.

[0050] The pick-and-place drive component 23 can be an electric cylinder, which is a modular product that integrates a servo motor and a lead screw, converting the rotary motion of the servo motor into linear motion. The slider on the electric cylinder, which is threaded to the lead screw, is connected to the pick-and-place arm 22. When the servo motor rotates, it drives the lead screw to rotate, thereby driving the slider to move the pick-and-place arm 22.

[0051] Furthermore, the tray support 21 is provided with a tray channel 210 extending from the storage compartment 1 to the edging station. The storage compartment 1 includes a storage rack 11 and a lifting assembly 12. Several lens trays 13 are spaced apart from top to bottom on the storage rack 11. The lifting assembly 12 is connected to the storage rack 11 to drive the storage rack 11 to rise and fall. When the lifting assembly 12 drives the storage rack 11 to rise and fall until one of the lens trays 13 is level with the tray channel 210, the pick-and-place arm 22 is connected to the lens tray 13 to move the lens tray 13 from the storage rack 11 to the tray channel 210 and / or move the lens tray 13 from the tray channel 210 to the storage rack 11. The lifting assembly 12 lifts the storage rack 11 up to one of the lens trays 13, which is level with the tray channel 210. Thus, the pick-and-place arm 22 can move the lens tray 13 by horizontal dragging. Compared with other moving methods, horizontal dragging has the shortest travel distance and is more efficient.

[0052] The lifting assembly 12 includes a lifting support 121 and a lifting drive 122. The lifting support 121 is located below the storage rack 11. The lifting drive 122 includes a servo motor, a lead screw connected to the servo motor, a bolt threaded to the lead screw, and a telescopic rod sleeved to the lead screw and fixedly connected to the bolt. The telescopic rod is connected to the storage rack 11. When the servo motor drives the lead screw to rotate, the bolt drives the telescopic rod to move, thereby driving the storage rack 11 to rise and fall.

[0053] The lifting assembly 12 also includes a guide sleeve 123 and a guide rod 124. The guide sleeve 123 is connected to the lifting support 121, and the guide rod 124 is connected to the storage rack 11. When the lifting drive component 122 drives the storage rack 11 to lift, the guide rod 124 moves relative to the guide sleeve 123. Through the cooperation of the guide rod 124 and the guide sleeve 123, the lifting of the storage rack 11 is guided, making the lifting of the storage rack 11 more stable.

[0054] Furthermore, the tray support 21 includes two parallel and opposing support and limiting modules 211. Each support and limiting module 211 has a tray support portion 2111 and a tray limiting portion 2112. The two tray support portions 2111 and the two tray limiting portions 2112 form the tray channel 210. When the lens tray 13 engages with the tray channel 210, the lens tray 13 is positioned on the two tray support portions 2111 and between the two tray limiting portions 2112. The two tray support portions 2111 provide stable support for the lens tray 13, and the two tray limiting portions 2112 effectively limit the movement of both sides of the lens tray 13, allowing the lens tray 13 to be placed more stably on the tray support 21.

[0055] Furthermore, the pick-and-place device 2 also includes a tray positioning assembly 24, which includes a positioning module 241 and a positioning drive 242. The tray limiting part 2112 is provided with a positioning mounting groove 2113 communicating with the tray channel 210. The lens tray 13 is provided with a tray positioning groove 1301. The positioning module 241 is movably disposed within the positioning mounting groove 2113. The positioning drive 242 is connected to the positioning module 241 to drive the positioning module 241 to extend into or retract from the tray positioning groove 1301. By cooperating with the tray positioning groove 1301, the horizontal movement of the lens tray 13 can be effectively restricted, making the lens tray 13 more stably placed on the tray support 21. Moreover, the more stable the position of the lens tray 13, the more precise the connection between the transfer device 3 and the lens 14, which is beneficial to improving the transfer accuracy.

[0056] The positioning drive component 242 can be a cylinder. When the piston rod of the cylinder extends or retracts, it drives the positioning module 241 to extend into or retract from the tray positioning groove 1301.

[0057] Furthermore, the lens tray 13 is provided with either a socket 1302 or a plug 221, and the pick-and-place arm 22 is provided with the other socket 1302 or plug 221. The pick-and-place device 2 also includes a plug-in drive 25, which is connected to the pick-and-place arm 22 to drive the pick-and-place arm 22 to move the plug 221 into or out of the socket 1302. The lens tray 13 and the pick-and-place arm 22 are connected and engaged through the socket 1302 and the plug 221, resulting in a simple structure and convenient connection and disconnection.

[0058] Preferably, the lens tray 13 is provided with an insertion hole 1302, and the pick-and-place arm 22 is provided with an insertion block 221. The pick-and-place arm is located below the tray channel 210. The insertion drive 25 can be a cylinder. When the piston rod of the cylinder extends or retracts, it drives the pick-and-place arm 22 to move, thereby causing the insertion block 221 to extend into or retract from the insertion hole 1302.

[0059] When it is necessary to remove the lens tray 13 from the storage compartment 1, the lifting assembly 12 drives the storage rack 11 to rise and fall until one of the lens trays 13 is level with the tray channel 210. The pick-and-place drive 23 drives the pick-and-place arm 22 to move towards the storage rack 11. When the pick-and-place arm 22 moves to the point where the insertion block 221 on the pick-and-place arm 22 is coaxially aligned with the insertion hole 1302 on the lens tray 13, the insertion drive 25 drives the pick-and-place arm 22 to move upward, causing the insertion block 221 to extend into the insertion hole. In hole 1302, the pick-and-place arm 22 is inserted and engaged with the lens tray 13. Then, the pick-and-place drive 23 drives the pick-and-place arm 22 to move the lens tray 13 away from the storage rack 11. When the pick-and-place arm 22 moves to the point where the tray positioning groove 1301 on the lens tray 13 is opposite to the positioning mounting groove 2113 on the tray support 21, the positioning drive 242 drives the positioning module 241 to extend into the tray positioning groove 1301, so that the lens tray 13 is positioned on the tray support 21.

[0060] When the lens tray 13 needs to be placed into the storage compartment 1, the positioning drive 242 drives the positioning module 241 to exit the tray positioning slot 1301. Then, the pick-and-place drive 23 drives the pick-and-place arm 22 to move the lens tray 13 toward the storage rack 11. When the lens tray 13 is fully inside the storage rack 11, the insertion drive 25 drives the pick-and-place arm 22 to move downward, causing the insertion block 221 to exit the insertion hole 1302, so that the pick-and-place arm 22 is disengaged from the lens tray 13. Then, the pick-and-place drive 23 drives the pick-and-place arm 22 to move away from the storage rack 11. The lifting assembly 12 then drives the storage rack 11 to rise and fall until another lens tray 13 is level with the tray channel 210, in preparation for the next removal of the lens tray 13.

[0061] Further, the transfer device 3 includes a suction assembly 31, an X-axis transfer assembly 32, a Y-axis transfer assembly 33, and a Z-axis transfer assembly 34; the suction assembly 31 includes a suction nozzle and a suction arm connecting the suction nozzle and the Z-axis transfer assembly 34; the X-axis transfer assembly 32 includes an X-axis transfer guide rail 321, an X-axis transfer slide 322, and an X-axis transfer drive 323, wherein the X-axis transfer guide rail 321 extends from the storage bin 1 to the edge grinding station. Extending further, the X-axis transfer slide 322 is slidably mounted on the X-axis transfer guide rail 321, and the X-axis transfer drive 323 is connected to the X-axis transfer slide 322 to drive the X-axis transfer slide 322 to move along the X-axis transfer guide rail 321; the Y-axis transfer assembly 33 includes a Y-axis transfer guide rail 331, a Y-axis transfer slide 332, and a Y-axis transfer drive 333, wherein the Y-axis transfer guide rail 331 is perpendicular to the X-axis transfer guide rail 321. The X-axis transfer guide rail 321 extends horizontally on the X-axis transfer slide 322, the Y-axis transfer slide 332 is slidably mounted on the Y-axis transfer guide rail 331, and the Y-axis transfer drive unit 333 is connected to the Y-axis transfer slide 332 to drive the Y-axis transfer slide 332 to move along the Y-axis transfer guide rail 331; the Z-axis transfer assembly 34 includes a Z-axis transfer guide rail 341 and a Z-axis transfer slide. 342. Z-axis transfer drive 343: The Z-axis transfer guide rail 341 extends vertically onto the Y-axis transfer slide 332. The Z-axis transfer slide 342 is slidably mounted on the Z-axis transfer guide rail 341 and connected to the suction assembly 31. The Z-axis transfer drive 343 is connected to the Z-axis transfer slide 342 to drive the Z-axis transfer slide 342 to move along the Z-axis transfer guide rail 341. Through the cooperation of the X-axis transfer assembly 32, Y-axis transfer assembly 33, and Z-axis transfer assembly 34, three-dimensional movement of the suction arm can be achieved to transfer the lens 14 from the lens tray 13 to the edging station 9 and / or transfer the lens 14 from the edging station 9 to the lens tray 13. The X-axis transfer drive 323, Y-axis transfer drive 333, and Z-axis transfer drive 343 can all be electric cylinders.

[0062] Furthermore, the transfer device 3 includes two suction components 31 and two Z-axis transfer components 34, which are connected in a one-to-one correspondence. The two Z-axis transfer components 34 can independently control the lifting and lowering of the two suction components 31.

[0063] Furthermore, the lens tray 13 includes a tray body 131 and a first frame 132 and a second frame 133 arranged side by side on the tray body 131. The first frame 132 is used to place the lens to be edged, and the second frame 133 is used to place the lens after edged processing.

[0064] The process of the transfer device 3 transferring the lens 14 from the lens tray 13 to the edging station 9 and vice versa is as follows: The X-axis transfer assembly 32 drives the two suction assemblies 31 to move above the lens tray 13. The first Z-axis transfer assembly 34 drives the corresponding first suction assembly 31 to move to a suitable height. After the first suction assembly 31 picks up the lens 14 to be edged from the first frame 132 in the lens tray 13, the X-axis transfer assembly 32 drives the two suction assemblies 31 to continue moving to the edging station 9 simultaneously. The second Z-axis transfer assembly 34 drives the corresponding second suction assembly 31 to move to a suitable height. After the second suction component 31 picks up the edge-ground lens 14, the Y-axis transfer component 33 moves both suction components 31 to a suitable position, and the first Z-axis transfer component 34 drives the first suction component 31 to move to a suitable height. The first suction component 31 then releases the lens 14 to be edge-ground at the edge-ground station 9. Subsequently, the X-axis transfer component 32 moves both suction components 31 above the lens tray 13, and the second Z-axis transfer component 34 drives the corresponding second suction component 31 to move to a suitable height. The second suction component 31 then releases the edge-ground lens 14 onto the second frame 133 in the lens tray 13. During this process, the Y-axis transfer component 33 drives the suction components 31 to move and adjust their positions according to the actual situation. The two suction components 31 work together to complete the loading and unloading operations in one transfer process, resulting in a high degree of automation and high work efficiency.

[0065] Furthermore, the system also includes a correction mechanism 8, which is located between the storage compartment 1 and the edging station. The transfer device 3 is used to transfer the lens from the lens tray 13 to the correction mechanism 8, and then from the correction mechanism 8 to the edging station and / or from the edging station to the lens tray 13. The correction mechanism 8 includes a correction support 81, correction clamping arms 82 located on both sides of the correction support 81, and a correction drive 83 that drives the two correction clamping arms 82 to move closer or further apart. The correction drive 83 can be a cylinder. When the transfer device 3 places the lens 14 on the correction support 81, the correction drive 83 drives the correction clamping arms 82 to move closer together, thereby moving the lens 14 to the center of the correction support 81 to determine the center position of the lens 14. Before the transfer device 3 transfers the lens 14 from the lens tray 13 to the edging station 9, the lens 14 is first corrected by the correction mechanism 8, which helps to ensure the lens edging effect.
