Description

Technical Field

[0001] This invention relates to the field of lens processing technology, and in particular to a lens core extraction device. Background Technology

[0002] The lens processing flow in the optical department generally includes the following steps: milling, fine grinding, polishing, cleaning, edging, coating, and bonding. The lens core-taking device is a piece of equipment used to grind and process lenses during eyeglass fitting. It consists of a core-taking machine and a water tank, and is generally used in optical shops for eye exams and eyeglass fitting. It grinds and retrieves the cores from glass and resin lenses, has a good core-taking effect, and low power consumption. It is widely used in lens processing and grinding.

[0003] In existing technologies, the general workflow of a core-taking machine is as follows: the lens to be processed is gripped in the lens box by a horizontal gripper, then dipped in polishing fluid and transported to a vertical gripper. After the lens is removed by the vertical gripper, it is transported to the core-taking station, and the freshly polished lens is transported from the core-taking station to the horizontal gripper. Finally, the horizontal gripper puts the lens back into the lens box. In this transportation method, the strokes of the horizontal and vertical grippers are too long. After the lens is polished at the core-taking station, a certain amount of time needs to be waited before the vertical gripper transports the lens to be processed. This results in idle time at the core-taking station, which reduces production efficiency. In addition, a flipping mechanism is provided between the horizontal and vertical grippers for connection. All three types of automated equipment are very expensive in terms of procurement and operating costs. Summary of the Invention In view of the shortcomings of the prior art, the purpose of this invention is to provide a lens core extraction device, which aims to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: A lens core-taking device includes a lens supply mechanism, a lens transport mechanism, a lens transfer mechanism, and a lens core-taking mechanism arranged sequentially according to processing steps. The lens transport mechanism includes a rotating block, a plurality of suction nozzles spaced apart on the rotating block, and a first drive assembly that drives the rotating block to rotate intermittently. The lens transfer mechanism includes a grooved plate, a clamping assembly that moves on the grooved plate, a second drive assembly that drives the clamping assembly to rotate, and a conveyor belt. The clamping assembly has a clamping state and a placement state when the grooved plate moves. The conveyor belt is arranged near the position of the clamping assembly in the placement state. The lens core-taking mechanism is located at the end of the conveyor belt. When the rotating block stops, the lens supply mechanism, the polishing fluid tank, and the clamping assembly in the clamping state are arranged sequentially near each of the suction nozzles.

[0005] According to one aspect of the above technical solution, the grooved plate is provided with a first sliding groove, and the clamping assembly includes a first rotating shaft rotatably connected to the grooved plate, a grooved rod connected to the first rotating shaft, a sliding rod that moves in the sliding groove of the grooved rod and the first sliding groove, a clamping rod connected to the sliding rod, a second rotating shaft rotatably connected to the grooved plate, and a clamping part connected to the second rotating shaft, wherein the clamping part is fixedly connected to the clamping rod.

[0006] According to one aspect of the above technical solution, the suction nozzle includes a telescopic rod connected to the rotating block and a suction nozzle body connected to the telescopic rod. The rotating block is provided with a sensor, which is located near the suction nozzle. When the sensor detects the lens supply mechanism, the polishing liquid tank, or the clamping assembly, the telescopic rod drives the suction nozzle body to extend or retract.

[0007] According to one aspect of the above technical solution, the first driving component includes a third rotating shaft, a motor that drives the third rotating shaft to rotate, a turntable connected to the third rotating shaft, a toggle lever and a contact block disposed on the turntable, a grooved wheel disposed near the turntable, and a fourth rotating shaft connecting the grooved wheel and the rotating block. The grooved wheel is provided with a strip groove, and the rotation of the turntable drives the toggle lever to move the strip groove, thereby causing the grooved wheel to rotate.

[0008] According to one aspect of the above technical solution, the second drive assembly includes a flywheel disk connected to the third rotating shaft, a fixed rod disposed on the flywheel disk, a fifth rotating shaft connected to the first rotating shaft, a gear disposed on the fifth rotating shaft, a connecting rod hinged to the fixed rod, a rack fixedly connected to the connecting rod, and a clamping seat rotatably connected to the fifth rotating shaft, wherein the rack meshes with the gear, and the clamping seat is fixedly connected to the rack.

[0009] According to one aspect of the above technical solution, the lens supply mechanism includes a lens box for placing the lens to be processed, a multi-section telescopic rod connected to the lens box, a push plate connected to one end of the multi-section telescopic rod near the rotating block, a drive rod connected to the push plate, a winding wheel provided on the fourth rotating shaft, and a pull wire connecting the drive rod and the winding wheel. The lens box is provided with a second sliding groove for the drive rod to slide.

[0010] According to one aspect of the above technical solution, the free end of the clamping rod is provided with a sliding groove plate and a clamping plate slidably connected to the sliding groove plate, and the sliding groove plate and the clamping plate are arranged opposite to each other.

[0011] According to one aspect of the above technical solution, the lens core-taking device further includes a support component for carrying the lens supply mechanism, the lens transmission mechanism, the lens transfer mechanism, and the lens core-taking mechanism.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: By sequentially setting up a lens supply mechanism, a lens transfer mechanism, a lens transfer mechanism, and a lens core-taking mechanism according to the processing steps, when lens core taking is required, the first drive component controls the rotating block to drive multiple suction nozzles on it to rotate intermittently. When a suction nozzle stops facing the lens supply mechanism, the next two suction nozzles of that nozzle are located in the polishing liquid tank and the clamping component in the clamping state, respectively. After the first suction nozzle picks up the lens to be processed from the lens supply mechanism, the first drive component controls the rotating block to rotate again, and the lens to be processed is located in the polishing liquid tank to dip in polishing liquid. The next rotation will place it in the clamping component in the clamping state. After the clamping component clamps the lens to be processed, the second drive component controls the clamping component to move on the groove plate to change the clamping component from the clamping state to the placing state, and then place the lens to be processed on the conveyor belt. The conveyor belt transports the lens to be processed to the lens core-taking mechanism, thereby realizing the turnover of the lens. This invention can transport lenses more efficiently, avoiding excessive time spent on lens turnover, which would lead to idle time in the lens core-taking mechanism.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] Please see Figures 1 to 7 The image shows a lens core-taking device according to an embodiment of the present invention, including a lens supply mechanism 10, a lens transfer mechanism 20, a lens transfer mechanism 30, and a lens core-taking mechanism arranged sequentially according to the processing steps. The lens transfer mechanism 20 includes a rotating block 21, a plurality of suction nozzles spaced apart on the rotating block 21, and a first drive assembly 50 that drives the rotating block 21 to rotate intermittently. The lens transfer mechanism 30 includes a grooved plate 71, a clamping assembly that moves on the grooved plate 71, a second drive assembly 60 that drives the clamping assembly to rotate, and a conveyor belt 31. The clamping assembly has a clamping state and a placement state when the grooved plate 71 moves. The conveyor belt 31 is arranged near the position of the clamping assembly in the placement state. The lens core-taking mechanism is located at the end of the conveyor belt 31. When the rotating block 21 stops, the lens supply mechanism 10, the polishing fluid tank 72, and the clamping assembly in the clamping state are arranged sequentially near each of the suction nozzles.

[0018] Understandably, this invention sequentially sets up a lens supply mechanism 10, a lens transfer mechanism 20, a lens transfer mechanism 30, and a lens core-taking mechanism according to the processing steps. When lens core taking is required, the first drive assembly 50 controls the rotating block 21 to drive multiple suction nozzles on it to rotate intermittently. When a suction nozzle stops facing the lens supply mechanism 10, the next two suction nozzles are located at the polishing liquid tank 72 and the clamping assembly in the clamping state, respectively. After the first suction nozzle picks up the lens 14 to be processed from the lens supply mechanism 10, After the first drive assembly 50 controls the rotating block 21 to rotate for the next time, the lens 14 to be processed is located at the polishing slurry tank 72 and dips into the polishing slurry. The next rotation will place it at the clamping assembly in the clamping state. After the clamping assembly clamps the lens 14 to be processed, the second drive assembly 60 controls the clamping assembly to move on the groove plate 71 to change the clamping assembly from the clamping state to the placing state, and then places the lens 14 to be processed at the conveyor belt 31. The conveyor belt 31 transports the lens 14 to the lens core taking mechanism, thereby realizing the turnover of the lens. This invention can transport lenses more efficiently, avoiding excessive time spent on lens turnover, which would lead to idle time in the lens core-taking mechanism.

[0019] Specifically, the suction nozzle includes a telescopic rod 22 connected to the rotating block 21 and a suction nozzle body 23 connected to the telescopic rod 22. The rotating block 21 is provided with a sensor 24, which is located near the suction nozzle. When the sensor 24 detects the lens supply mechanism 10, the polishing liquid tank 72, or the clamping assembly, the telescopic rod 22 drives the suction nozzle body 23 to extend or retract.

[0020] Understandably, when the first drive assembly 50 controls the rotating block 21 to stop rotating intermittently, the sensor 24 will control the telescopic rod 22 to extend and drive the suction nozzle body 23 to pick up the lens when it senses any one of the lens supply mechanism 10, the polishing liquid tank 72, or the clamping assembly, and then retract to the original position.

[0021] Furthermore, the grooved plate 71 is provided with a first sliding groove 32. The clamping assembly includes a first rotating shaft rotatably connected to the grooved plate 71, a grooved rod 33 connected to the first rotating shaft, a sliding rod 34 that moves simultaneously in the sliding groove of the grooved rod 33 and the first sliding groove 32, a clamping rod 35 connected to the sliding rod 34, a second rotating shaft 36 rotatably connected to the grooved plate 71, and a clamping part 37 connected to the second rotating shaft 36. The clamping part 37 is fixedly connected to the clamping rod 35. The first driving assembly 50 includes a third rotating shaft 54, a motor 51 that drives the third rotating shaft 54 ​​to rotate, a turntable 52 connected to the third rotating shaft 54, a toggle rod 55 and a contact block 53 provided on the turntable 52, and a contact block near the turntable 52. The set grooved wheel 56 and the fourth rotating shaft 58 connecting the grooved wheel 56 and the rotating block 21 are provided. The grooved wheel 56 is provided with a strip groove 57. The rotation of the turntable 52 drives the actuating rod 55 to actuate the strip groove 57, so that the grooved wheel 56 rotates. The second drive assembly 60 includes a flywheel 61 connected to the third rotating shaft 54, a fixed rod 63 provided on the flywheel 61, a fifth rotating shaft 64 connected to the first rotating shaft, a gear 67 provided on the fifth rotating shaft 64, a connecting rod 62 hinged to the fixed rod 63, a rack 66 fixedly connected to the connecting rod 62, and a clamping seat 65 rotatably connected to the fifth rotating shaft 64. The rack 66 meshes with the gear 67, and the clamping seat 65 is fixedly connected to the rack 66.

[0022] Understandably, when lenses need to be rotated, the motor 51 drives the third rotating shaft 54 ​​to rotate, which in turn drives the turntable 52 to rotate. When the turntable 52 rotates, the actuating lever 55 enters the slot 57 and actuates the slotted wheel 56 to rotate one position, thus achieving intermittent rotation of the slotted wheel 56. This, in turn, drives the rotating block 21 and the suction nozzle to rotate intermittently via the fourth rotating shaft 58, thereby sequentially completing the actions of lens suction, lens dipping in polishing fluid, and lens transfer to the clamping assembly. When the turntable 52 rotates, the flywheel 61 connected to the third rotating shaft 54 ​​also rotates. Since the fixed rod 63 is not at the axis of the flywheel 61, the connecting rod 62 hinged to the fixed rod 63, together with the rack 66, reciprocates under the constraint of the clamping seat 65. This causes the gear 67 to rotate continuously in both directions, driving the fifth rotating shaft 64, together with the first rotating shaft, to rotate in the forward direction, causing the slotted rod 33 to rotate back and forth in the first sliding groove 32, thus enabling the clamping rod 35 to achieve the action as shown in the attached manual. Figure 4 and 7 The actions within the system allow for switching between the grab and place states.

[0023] Furthermore, the free end of the clamping rod 35 is provided with a sliding groove plate 38 and a clamping plate 39 slidably connected to the sliding groove plate 38, and the sliding groove plate 38 and the clamping plate 39 are arranged opposite to each other.

[0024] Understandably, a sensing component can be installed at the slide plate 38, and a slide rail cylinder can be installed at the clamping plate 39. When the clamping rod 35 is in the clamping state and the placement state, the slide rail cylinder controls the clamping plate 39 to move on the slide plate 38, thereby realizing the clamping and release of the lens 14 to be processed.

[0025] Furthermore, the lens supply mechanism 10 includes a lens box 11 for placing the lens 14 to be processed, a multi-section telescopic rod 12 connected to the lens box 11, a push plate 13 connected to one end of the multi-section telescopic rod 12 near the rotating block 21, a drive rod 15 connected to the push plate 13, a winding wheel 19 provided on the fourth rotating shaft 58, and a pull wire 17 connecting the drive rod 15 and the winding wheel 19. The lens box 11 is provided with a second sliding groove 16 for the drive rod 15 to slide.

[0026] Understandably, when the fourth rotating shaft 58 rotates intermittently, it will drive the pull wire 17 through the winding wheel 19 to pull the drive rod 15 a certain distance, so that the push plate 13 pushes the lens to be processed 14 toward the suction nozzle, so that the suction nozzle body 23 can reach the lens when it is extended. When the lens is used up, the push plate 13 can be manually or through other equipment pulled back to its original position and the lens can be repositioned.

[0027] Furthermore, the lens core-taking device also includes a support component 70 for carrying the lens supply mechanism 10, the lens transfer mechanism 20, the lens transfer mechanism 30, and the lens core-taking mechanism.

[0028] In summary, the lens core-taking device in the above embodiments of the present invention, by sequentially setting up a lens supply mechanism, a lens transmission mechanism, a lens transfer mechanism, and a lens core-taking mechanism according to the processing steps, when lens core-taking is required, the first drive component controls the rotating block to drive multiple suction nozzles on it to rotate intermittently. When a suction nozzle stops facing the lens supply mechanism, the next two suction nozzles of that suction nozzle are respectively located in the polishing liquid tank and the clamping component in the clamping state. After the first suction nozzle picks up the lens to be processed from the lens supply mechanism, the first drive component controls the rotating block to rotate again, and the lens to be processed is located in the polishing liquid tank to dip in polishing liquid. The next rotation will place it in the clamping component in the clamping state. After the clamping component clamps the lens to be processed, the second drive component controls the clamping component to move on the groove plate to change the clamping component from the clamping state to the placing state, and then place the lens to be processed on the conveyor belt. The conveyor belt transports the lens to be processed to the lens core-taking mechanism, thereby realizing the turnover of the lens. This invention can transport lenses more efficiently, avoiding excessive time spent on lens turnover, which would lead to idle time in the lens core-taking mechanism.
