[0030] 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.

[0031] Please see Figures 1 to 7This embodiment provides a storage-type automatic feeding device for an edging machine, including a storage bin 1, a pick-and-place mechanism 2, and a transfer mechanism 3. The storage bin 1 is provided with a plurality of lens trays 13. The pick-and-place mechanism 2 is used to remove the lens trays 13 from the storage bin 1 and / or place the lens trays 13 into the storage bin 1. The transfer mechanism 3 is used 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. This embodiment describes a storage-type automatic feeding device for an edging machine. It has a storage compartment 1 that can store multiple lens trays 13. During the feeding process at the edging station 9, the lens trays 13 can be moved out of the storage compartment 1 by the pick-and-place mechanism 2, and then the lenses 14 can be transferred from the lens trays 13 to the edging station 9 by the transfer mechanism 3. After processing is completed, the lenses 14 can be transferred from the edging station 9 to the lens trays 13 by the transfer mechanism 3, and then the lens trays 13 can be placed back into the storage compartment 1 by the pick-and-place mechanism 2. No dedicated personnel are required to be stationed there, which can effectively reduce labor costs, save time and effort, and has a high degree of automation.

[0032] Furthermore, the pick-and-place mechanism 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Furthermore, the picking and placing mechanism 2 also includes a tray positioning component 24, which includes a positioning module 241 and a positioning drive component 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 component 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. Through the cooperation of the positioning module 241 and the tray positioning groove 1301, the movement of the lens tray 13 in the horizontal direction can be effectively restricted, so that the lens tray 13 is placed more stably on the tray support 21. Moreover, the more stable the position of the lens tray 13, the more precise the connection between the transfer mechanism 3 and the lens 14, which is beneficial to improving the transfer accuracy.

[0039] 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.

[0040] 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 mechanism 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] Further, the transfer mechanism 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.

[0045] Furthermore, the transfer mechanism 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.

[0046] 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.

[0047] The process of the transfer mechanism 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 component 32 drives the two suction components 31 to move above the lens tray 13. The first Z-axis transfer component 34 drives the corresponding first suction component 31 to move to a suitable height. After the first suction component 31 picks up the lens 14 to be edged from the first frame 132 in the lens tray 13, the X-axis transfer component 32 drives the two suction components 31 to continue moving to the edging station 9. The second Z-axis transfer component 34 drives the corresponding second suction component 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.

[0048] Furthermore, the system also includes a calibration mechanism 8, which is located between the storage compartment 1 and the edging station. The transfer mechanism 3 is used to transfer the lens from the lens tray 13 to the calibration mechanism 8, and then transfer the lens from the calibration mechanism 8 to the edging station and / or transfer the lens from the edging station to the lens tray 13. The calibration mechanism 8 includes a calibration support 81, calibration clamping arms 82 located on both sides of the calibration support 81, and a calibration drive 83 that drives the two calibration clamping arms 82 to move closer or further apart. The calibration drive 83 can be a cylinder. When the transfer mechanism 3 places the lens 14 on the calibration support 81, the calibration drive 83 drives the calibration clamping arms 82 to move closer together, thereby moving the lens 14 to the center of the calibration support 81 to determine the center position of the lens 14. Before the transfer mechanism 3 transfers the lens 14 from the lens tray 13 to the edging station 9, the lens 14 is first calibrated by the calibration mechanism 8, which helps to ensure the lens edging effect.
