Description

Technical Field

[0001] This application relates to the field of lens processing technology, and in particular to a thin lens control device and control method. Background Technology

[0002] Polishing of optical components is a process performed after rough machining and is the most important step in achieving optical surface precision for optical elements. An ultrathin lens is actually a spherical optical component with a severely imbalanced ratio between its center thickness and outer diameter thickness; the difference between its center thickness and outer diameter thickness is enormous, which presents certain difficulties in the production and processing of ultrathin lenses.

[0003] In the existing technology, the polishing of ultrathin lenses involves first fixing the lens with a fixture, and then grinding and polishing its surface from coarse to fine. Since the thickness at the center of the ultrathin lens differs greatly from the thickness at the outer diameter, in order to ensure that the lens is subjected to uniform force and improve the control stability of the lens during the grinding process, it is usually necessary to lay pads (capacitor paper) of different thicknesses in the fixture to facilitate more precise control of the lens.

[0004] Regarding the aforementioned technologies, during the lens polishing process, pads of varying thicknesses are typically laid manually inside the fixture, resulting in extremely low pad feeding efficiency and severely impacting the lens polishing efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] In order to improve the feeding efficiency of padding and the polishing efficiency of lenses, this application provides a thin lens control device and control method.

[0006] Firstly, the thin lens control device provided in this application adopts the following technical solution: A thin lens control device includes a frame and a worktable rotatably mounted on the frame. The worktable is provided with several sets of clamp seats for supporting the lens body and the pad. A storage cylinder for storing the pad is provided on one side of the worktable. A rotating arm is rotatably mounted between the worktable and the storage cylinder. An adsorption component for adsorbing the pad is provided on the rotating arm. A lifting component for driving the adsorption component to move up and down is provided on the rotating arm. A rotating component for driving the pad to rotate is provided on the rotating arm.

[0007] By adopting the above technical solution, the adsorption component adsorbs the single layer of padding cloth inside the storage cylinder, and the rotating component drives the adsorption component to rotate the padding cloth, so as to reduce the adsorption component adsorbing multiple layers of padding cloth and facilitate the padding cloth adsorbed by the adsorption component to be laid flat inside the clamp seat; the lifting component and the rotating arm cooperate with each other to facilitate the movement of the position of the adsorption component, thereby realizing the mechanized and precise feeding of the padding cloth, and thus improving the feeding efficiency of the padding cloth and the polishing efficiency of the lens.

[0008] Preferably, the adsorption assembly includes an adsorption plate, an adsorption tube, and an adsorption element; the adsorption plate is disposed on the side of the rotating arm facing the storage cylinder, and the adsorption tube is connected to the adsorption plate for inserting into the storage cylinder; the adsorption element is disposed between the adsorption tube and the rotating arm for sucking up and fixing the pad cloth.

[0009] By adopting the above technical solution, the adsorption component draws air to generate an adsorption force on the adsorption plate through the adsorption tube, thereby enabling the adsorption plate to adsorb the middle part of the single-layer pad.

[0010] Preferably, the adsorption assembly further includes an adsorption ring tube and an adsorption element; the adsorption ring tube is disposed on the side of the rotating arm facing the storage cylinder, and the side wall of the adsorption ring tube facing the storage cylinder has several sets of ventilation holes, and the adsorption tube is located inside the adsorption ring tube; the adsorption element is disposed between the rotating arm and the adsorption ring tube for adsorbing the edge of the pad cloth.

[0011] By adopting the above technical solution, the suction component draws air, so that the suction ring tube generates a suction effect at all the vent holes, so as to attract or adsorb the edge of the pad, so that the edge of the pad is attracted to warp towards the direction of the suction ring tube, and it is convenient to lay the pad flat and unfold, thereby facilitating the quick laying of the pad into the fixture seat.

[0012] Preferably, the lifting assembly includes a fixed frame, a lifting block, a lifting screw, and a lifting motor; the fixed frame is mounted on the rotating arm, and the length direction of the fixed frame is parallel to the height direction of the storage cylinder; the lifting block is slidably mounted on the fixed frame, the lifting screw is rotatably mounted on the fixed frame, the lifting screw passes through the lifting block, and the lifting screw is threadedly connected to the lifting block; the lifting motor is mounted on the fixed frame to drive the lifting screw to rotate.

[0013] By adopting the above technical solution, the output end of the lifting motor drives the lifting screw to rotate, and the rotating lifting screw drives the lifting block, so that the lifting block drives the rotating component and the adsorption component to move up and down.

[0014] Preferably, the rotating assembly includes a rotating plate, a rotating shaft, and a driving component; the rotating plate is disposed on the lifting block, and the adsorption component and the suction component are both connected to the rotating plate; the rotating shaft is rotatably disposed on the lifting block, and the rotating shaft is connected to the rotating plate; the driving component is disposed on the lifting block to drive the rotating shaft to rotate.

[0015] By adopting the above technical solution, the driving component drives the rotating plate and rotating shaft to rotate, so that the rotating plate drives the adsorption assembly and the pad cloth to rotate as a whole. On the one hand, it reduces the number of multiple layers of pad cloth adsorbed on the adsorption plate, ensuring that the adsorption plate only adsorbs a single layer of pad cloth at a time; on the other hand, it facilitates the pad cloth to gradually flatten under the influence of its own centrifugal force, so as to quickly lay the pad cloth flat on the clamp seat and improve the feeding efficiency of the pad cloth.

[0016] Preferably, the driving component includes a fixed rack, a drive shaft, a drive gear, a drive bevel gear, and a drive bevel gear; the fixed rack extends along the height direction of the fixed frame and is disposed on the fixed frame; the drive shaft is rotatably disposed on the lifting block; the drive gear is sleeved on the drive shaft and meshes with the fixed rack; the drive bevel gear is sleeved on the drive shaft; the drive bevel gear is sleeved on the rotating shaft and meshes with the drive bevel gear.

[0017] By adopting the above technical solution, during the lifting block's movement relative to the fixed rod, the fixed rack drives the transmission gear and transmission shaft to rotate. The rotating transmission bevel gear meshes with the drive bevel gear to drive the rotating shaft and rotating plate to rotate. The operation of the lifting component realizes the drive of the rotating component, reducing the need for an additional power source to drive the rotating component and saving costs.

[0018] Preferably, the storage cylinders are arranged in several groups at intervals along the length of the frame, and the thickness of the padding cloth inside each storage cylinder is different; the frame is provided with a moving component for driving the rotating arm to move between the worktable and any storage cylinder.

[0019] By adopting the above technical solution, the moving component drives the rotating arm to reciprocate between the worktable and any storage cylinder, so as to facilitate the feeding of pads of different thicknesses and sizes.

[0020] Preferably, the moving component includes a mounting frame, a moving block, a moving screw, a moving motor, and a rotating component; the mounting frame extends along the distribution direction of the storage cylinder and is disposed on the frame; the moving block is slidably disposed on the mounting frame along the length direction of the mounting frame; the moving screw is rotatably disposed on the mounting frame, the moving screw passes through the moving block, and the moving screw is threadedly connected to the moving block; the moving motor is disposed on the mounting frame to drive the moving screw to rotate; the rotating component is disposed on the mounting frame to drive the rotating arm to rotate.

[0021] By adopting the above technical solution, the output end of the moving motor drives the moving screw to rotate, and the rotating moving screw drives the moving block, so that the moving block drives the rotating arm to move along the arrangement direction of the storage cylinder; and in conjunction with the rotating component, the rotating arm is driven to rotate, so as to realize the reciprocating movement of the rotating arm between the worktable and any storage cylinder.

[0022] Preferably, the rotating component includes a reference shaft, a missing gear, a drive rack, a positioning cylinder, a torque element, a positioning block, and a positioning rod; the reference shaft is rotatably mounted on the moving block and connected to the rotating arm; the missing gear is sleeved on the reference shaft; the drive rack is spaced along the length of the mounting frame, with each drive rack corresponding to a storage cylinder, and each drive rack is used to mesh with the missing gear; the drive rack is slidably connected to the mounting frame; the positioning cylinder is located between the mounting frame and each set of drive racks to drive the drive racks to move up and down; The torque element is disposed between the rotating arm and the moving block to drive the rotating arm toward the worktable through its own torque; the positioning block is disposed on the missing gear, and the positioning rod is disposed on the moving block to restrict the rotation of the positioning block.

[0023] By adopting the above technical solution, the torque component provides torque to the rotating arm, and the positioning block and positioning rod abut against each other to limit the orientation of the rotating arm after twisting, so that the end of the rotating arm is away from the moving block, that is, the adsorption component is facing the fixture seat on the worktable. This also ensures that the adsorption component and other structures on the rotating arm are always directly above the mounting frame during the movement of the rotating arm following the moving block, reducing the phenomenon of the rotating arm interfering with other equipment on the worktable, so as to reduce the space occupied by the overall equipment. In addition, it also reduces the phenomenon of the rotating arm rotating randomly during the movement of the rotating arm following the moving block, so as to facilitate the meshing transmission between the gear on the rotating arm and the drive rack, ensuring the operational stability of the rotating arm. When it is necessary to adsorb the padding cloth inside a certain storage cylinder, the output end of the positioning cylinder is activated to drive the corresponding drive rack to move, so that the corresponding drive rack and the missing gear are on the same horizontal plane. With the help of the movement of the moving block, after the drive rack and the missing gear mesh and drive, the end of the rotating arm carrying the adsorption component faces the corresponding storage cylinder, thereby reducing the need for an additional power source to drive the rotating arm and saving costs.

[0024] Secondly, This application provides a control method for a thin lens control device, comprising the following steps: Adsorption: The lifting component controls the adsorption component to press against the inside of the storage cylinder, and the adsorption component adsorbs the padding cloth inside the storage cylinder; Rotation: The rotation component drives the adsorption component to rotate the pad cloth; Transfer: The rotating arm and lifting assembly control the adsorption assembly to move from inside the storage cylinder to above the worktable; Placement: The lifting component controls the adsorption component to approach the clamp seat and controls the adsorption component to place the pad inside the clamp seat.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up an adsorption component to adsorb the single layer of padding cloth inside the storage cylinder, the rotating component drives the adsorption component to rotate the padding cloth, which reduces the adsorption component from adsorbing multiple layers of padding cloth and facilitates the adsorbed padding cloth to be laid flat inside the clamp seat; the lifting component and the rotating arm cooperate with each other to move the position of the adsorption component, thereby realizing the mechanized and precise feeding of padding cloth, thereby improving the feeding efficiency of padding cloth and the polishing efficiency of lens. 2. By setting a moving component, the rotating arm is driven to reciprocate between the worktable and any storage cylinder, so as to facilitate the feeding of pads of different thicknesses and sizes.

The rotating worktable 11 directs the clamp seats 111, which hold the pad 112 and the lens body 110, toward a polishing device for polishing the lens body 110.

[0037] Reference Figure 2 and Figure 3 The rotating assembly 4 includes a rotating plate 41, a rotating shaft 42, and a driving component 43. The rotating shaft 42 is rotatably connected to the side wall of the lifting block 32 facing the worktable 11, and the rotating plate 41 is fixedly connected to the end of the rotating shaft 42 away from the lifting block 32. The suction assembly is located on the rotating plate 41, and the driving component 43 is mounted on the lifting block 32 to drive the rotating shaft 42 to rotate the rotating plate 41 and the suction assembly.

[0038] Reference Figure 2 and Figure 3 The driving component 43 includes a fixed rack 431, a drive shaft 432, a drive gear 433, a drive bevel gear 434, and a drive bevel gear 435. The fixed rack 431 is fixedly installed on the side wall of the fixed frame 31 facing the lifting block 32, and the length direction of the fixed rack 431 is parallel to the height direction of the fixed frame 31.

The adsorption tube 22 is located inside the suction ring tube 24, and the suction ring tube 24 is located on the side of the adsorption plate 21 facing the adsorption tube 22. Several sets of vent holes 241 are opened through the side wall of the suction ring tube 24 away from the suction element 25. All the vent holes 241 are distributed circumferentially along the suction ring tube 24 to attract external gas into the vent holes 241, thereby causing the edge of the pad 112 to warp towards the suction ring tube 24.

[0042] Reference Figure 1 and Figure 4 In this embodiment, a hemispherical arched material block 121 is fixedly connected to the bottom of each storage cylinder 12.

[0045] Reference Figure 1 and Figure 4 The rotating component 55 is mounted on the mounting bracket 51 to drive the rotating arm 13 to rotate. The rotating component 55 includes a reference shaft 551, a gear 552, a drive rack 553, a positioning cylinder 554, a torque component 555, a positioning block 556, and a positioning rod 557.

[0046] Reference Figure 1 and Figure 4 The missing gear 552 is fixedly sleeved on the reference shaft 551. In this embodiment, the torque member 555 is a torsion spring, which is sleeved on the reference shaft 551. One end of the torque member 555 is fixedly connected to the missing gear 552, and the other end of the torque member 555 is fixedly connected to the moving block 52, so as to provide the force for the rotating arm 13 to turn towards the worktable 11 through the torque of the torque member 555 itself. The positioning block 556 is integrally formed on the peripheral wall of the missing gear 552, and the positioning rod 557 is fixedly connected to the side wall of the moving block 52. The side wall of the positioning block 556 facing the worktable 11 abuts against the positioning rod 557 to restrict the rotation of the missing gear 552, the reference shaft 551, and the rotating arm 13, so that the end of the rotating arm 13 away from the moving block 52 remains facing the worktable 11.

[0047] Reference Figure 1 and Figure 4In this embodiment, the drive rack 553, positioning cylinder 554, and storage cylinder 12 are respectively arranged in a one-to-one correspondence.

The extension and retraction direction of the output end of each set of positioning cylinders 554 is parallel to the length direction of the reference shaft 551, and all positioning cylinders 554 are spaced apart along the length direction of the mounting frame 51. Each set of drive racks 553 is fixedly connected to the output end of the corresponding positioning cylinder 554, and each set of drive racks 553 is slidably connected to the mounting frame 51 through a slider, so that the positioning cylinder 554 drives the corresponding drive rack 553 to slide up and down. Each set of drive racks 553 is used to mesh with the missing gear 552 to drive the missing gear 552 and the reference shaft 551 to rotate.

[0048] The implementation principle of a thin lens control device according to an embodiment of this application is as follows: The output of the lifting motor 34 drives the lifting screw 33 to rotate, causing the lifting block 32 to move the adsorption plate 21 up and down. The moving adsorption plate 21 enters the storage cylinder 12, activating the adsorption element 23, so that the adsorption plate 21 adsorbs the center part of the pad 112.

[0049] The rotating lifting screw 33 drives the lifting block 32 to raise the adsorption plate 21, and drives the rotating shaft 42 and rotating plate 41 to rotate the adsorption plate 21 and the pad 112. After the rotating arm 13 drives the adsorption plate 21 to move the pad 112 above the empty fixture seat 111, the rotating lifting screw 33 drives the lifting block 32 to lower the adsorption plate 21 and gradually approach the fixture seat 111. The rotating shaft 42 drives the adsorption plate 21 and the pad 112 to rotate. The pad 112 is subjected to centrifugal force and gradually flattens out, so that the flattened pad 112 is quickly laid flat inside the fixture seat 111, realizing the mechanized and precise feeding of the pad 112, thereby improving the feeding efficiency of the pad 112 and the polishing efficiency of the lens.

[0050] This application also discloses a control method for a thin lens control device, comprising the following steps: Adsorption: The lifting component 3 controls the adsorption component 2 to press against the inside of the storage cylinder 12, and the adsorption component 2 adsorbs the pad 112 inside the storage cylinder 12. Rotation: Rotation component 4 drives adsorption component 2 to rotate pad 112; Transfer: The rotating arm 13 and the lifting assembly 3 control the adsorption assembly 2 to move from inside the storage cylinder 12 to above the worktable 11; Placement: The lifting component 3 controls the adsorption component 2 to approach the clamp seat 111 and controls the adsorption component 2 to place the pad 112 inside the clamp seat 111.

[0051] Specifically, pad 112 typically uses yellow damping cloth with a thickness of 0.5mm, rose red damping cloth with a thickness of 0.6mm, and pink damping cloth with a thickness of 0.8mm. When the center thickness of the lens body 110 is large, a thinner yellow damping cloth is selected as the pad 112. When the center thickness of the lens body 110 is appropriate, a thinner rose-red damping cloth is selected as the pad 112. When the center thickness of the lens body 110 is small, a thicker pink damping cloth is selected as the pad 112, or a combination of a thinner yellow damping cloth and a rose red damping cloth is selected as the pad 112.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
