[0011] As a further preferred embodiment of the technical solution, the solution also includes a polishing method using the above-mentioned automatic polishing device for the inner wall of an optical lens barrel, comprising the following steps:

[0012] S1. Place several optical lens barrels inside the feeding rack. The gravity of the optical lens barrels will drive the optical lens barrels to gradually fall down. The optical lens barrel at the bottom will be stored in the storage slot of the feeding tray. At this time, the driven gear and the driving gear are in meshing state. The driving gear is driven to rotate by the polishing motor. The meshing of the driven gear and the driving gear will drive the rotating rod to rotate, and then the feeding tray will be driven to rotate, and the optical lens barrel stored in the storage slot of the feeding tray will be rotated to the top. At this time, the optical lens barrel at the bottom is stored in the next storage slot of the feeding tray under the action of gravity.

[0013] S2, the screw is driven to rotate by the moving motor, and the threaded connection between the screw and the moving frame will drive the moving frame to move between the two guide rails to control the polishing roller to approach the optical lens barrel. At this time, the trapezoidal positioning block will first contact the optical lens barrel, and the end of the optical lens barrel will be squeezed by the inclined surfaces on the two trapezoidal positioning blocks to control the positioning of the optical lens barrel between the two trapezoidal positioning blocks. At the same time, the trapezoidal positioning block will push the optical lens barrel to slide inside the storage groove until the end of the optical lens barrel contacts the baffle. With the continuous movement of the moving frame, the sliding rod connected to the trapezoidal positioning block will slide inside the sliding hole due to the reverse squeezing of the optical lens barrel. At this time, the reset spring is in a compressed state. With the continuous movement of the moving frame, the polishing roller on the moving frame will gradually be inserted into the inner wall of the optical lens barrel. The rotation of the polishing roller driven by the polishing motor will be used to polish the inner wall of the optical lens barrel. At the same time, through the operation of the dust suction component, the impurities polished on the inner wall of the optical lens barrel will be acutely absorbed by the dust suction pipe to ensure the cleanliness of the polishing area.

[0014] S3, then the moving motor drives the screw rod to rotate in the opposite direction, which will drive the moving frame to move in the opposite direction between the two guide rails, and the polishing roller will gradually slide out of the inner wall of the optical lens barrel. During this process, the trapezoidal positioning block is pushed by the return spring in the compressed state to keep the trapezoidal positioning block continuously squeezing the optical lens barrel, so as to ensure the stable sliding of the polishing roller from the inside of the optical lens barrel. With the continuous movement of the moving frame, the moving frame will move to the position where the driven gear and the driving gear are meshed. At this time, the trapezoidal positioning block will cancel the squeezing of the optical lens barrel, and the driving gear will rotate through the polishing motor, which will drive the feed tray to rotate. The topmost, polished optical lens barrel will slide out of the storage slot of the feed tray by the rotation of the feed tray. At the same time, the optical lens barrel stored in the next storage slot of the feed tray will be driven to rotate to the topmost point;

[0015] S4. Repeat the operations in S2 and S3 to polish the optical lens barrels one by one.

[0016] The present invention provides an automatic polishing device for the inner wall of an optical lens barrel and a polishing method thereof, which has the following features:

[0017] Beneficial effects:

[0018] (1) The present invention places a plurality of optical lens barrels inside a feed rack, wherein the optical lens barrel at the bottom is stored inside a storage slot of the feed tray, and the feed tray is driven to rotate by the operation of a polishing motor, so that the optical lens barrel stored inside the storage slot of the feed tray is rotated to the top, and the moving rack is driven to move between two guide rails by the operation of a moving motor, and the end of the optical lens barrel is squeezed by the inclined surfaces on two trapezoidal positioning blocks to control the positioning of the optical lens barrel between the two trapezoidal positioning blocks, thereby ensuring that the polishing roller corresponds to the optical lens barrel. As the moving rack continues to move, the polishing roller on the moving rack is gradually inserted into the inner wall of the optical lens barrel, and the polishing roller is driven to rotate by the polishing motor to perform a polishing operation on the inner wall of the optical lens barrel, thereby realizing automatic polishing of the inner wall of the optical lens barrel.

[0019] (2) After the present invention polishes the inner wall of the previous optical lens barrel by the polishing roller, the polishing roller is controlled to slide out of the inner wall of the optical lens barrel. As the moving frame continues to move, the moving frame will move to a position where the driven gear and the driving gear are meshed. The polishing motor drives the driving gear to rotate, which will drive the feed tray to rotate, and drive the optical lens barrel stored in the next storage slot of the feed tray to rotate to the top, thereby realizing synchronous loading and unloading of the optical lens barrel. At the same time, the operation of the polishing motor can not only polish the inner wall of the optical lens barrel, but also be used to load and unload the optical lens barrel, thereby reducing the complexity of the operation of the device.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The present invention provides a technical solution: Figures 1 to 4 As shown, in this embodiment, an automatic polishing device for the inner wall of an optical lens barrel and a polishing method thereof are provided. The automatic polishing device for the inner wall of an optical lens barrel comprises a feed frame 1 and a base 2. The feed frame 1 is used to transport the optical lens barrel. The feed frame 1 is arranged in an inclined manner. The optical lens barrel will be driven to gradually fall down by the gravity of the optical lens barrel, and is used to load the optical lens barrel one by one. A rotating rod 3 is rotatably installed at the bottom end of the feed frame 1 through a damping bearing. A feed tray 4 is fixedly installed in the middle of the rotating rod 3. The outer side of the feed tray 4 is provided with a ring array with the central axis of the feed tray 4 as the axis for storing optical The storage slot 5 of the lens barrel will drive the optical lens barrel to slide into the storage slot 5 of the feed tray 4 under the action of its own gravity, so as to gradually transport the optical lens barrel to the polishing position. A moving frame 6 is slidably installed on the top of the base 2, and a polishing motor 7 is fixedly installed on one side of the top of the moving frame 6. A polishing roller 8 is fixedly installed on the output end of the polishing motor 7 through the moving frame 6. A trapezoidal positioning block 9 for accurately positioning the optical lens barrel is symmetrically installed on the top of the moving frame 6. The trapezoidal positioning block 9 first positions the optical lens barrel, and then the polishing roller 8 is inserted into the interior of the optical lens barrel.

[0027] like Figures 1 to 4 As shown, a baffle 10 for blocking the optical lens barrel is fixedly mounted on one side of the bottom end of the feeding frame 1.

[0028] When the two trapezoidal positioning blocks 9 position and squeeze the optical lens barrel, the optical lens barrel will be driven to move, and the final moving position of the optical lens barrel is positioned by the baffle 10 .

[0029] like Figures 1 to 4 As shown, a dust suction pipe 11 is fixedly installed in the middle of the baffle 10, and the dust suction pipe 11 is connected to the dust suction assembly.

[0030] When the polishing roller 8 is inserted into the inner wall of the optical lens barrel to polish the inner wall of the optical lens barrel, the impurities polished on the inner wall of the optical lens barrel are absorbed by the dust suction pipe 11 to ensure the cleanliness of the polishing area.

[0031] like Figures 1 to 4 As shown, guide rails 12 are symmetrically fixedly installed on the top of the feed frame 1, and the mobile frame 6 is slidably installed between the two guide rails 12. Mounting blocks 13 are fixedly installed on the top of both ends of the feed frame 1, and a screw 14 is rotatably installed between the two mounting blocks 13 through a bearing. The screw 14 is threadedly connected to the middle part of the mobile frame 6, and a mobile motor 15 is fixedly installed on one side of one of the mounting blocks 13 at a position corresponding to the screw 14, and the output end of the mobile motor 15 is fixedly connected to the end of the screw 14.

[0032] The screw rod 14 is driven to rotate by the moving motor 15 , and the screw rod 14 is threadedly connected to the moving frame 6 to drive the moving frame 6 to move between the two guide rails 12 , so as to control the polishing roller 8 to approach the optical lens barrel.

[0033] like Figures 1 to 4 As shown, a sliding hole 16 is symmetrically opened on the top of the movable frame 6, and a sliding rod 17 is slidably installed inside the sliding hole 16. One end of the sliding rod 17 is fixedly connected to the trapezoidal positioning block 9. A return spring 18 is sleeved on the outer side of one end of the sliding rod 17 close to the trapezoidal positioning block 9. One end of the return spring 18 is fixedly connected to the trapezoidal positioning block 9, and the other end of the return spring 18 is fixedly connected to the movable frame 6.

[0034] When the polishing roller 8 is controlled to approach the optical lens barrel, the trapezoidal positioning block 9 will first contact the optical lens barrel, and the end of the optical lens barrel will be squeezed by the inclined surfaces on the two trapezoidal positioning blocks 9, so as to control the optical lens barrel to be positioned between the two trapezoidal positioning blocks 9, and ensure that the polishing roller 8 corresponds to the optical lens barrel. As the moving frame 6 continues to move, the slide bar 17 connected to the trapezoidal positioning block 9 will slide inside the slide hole 16 under the reverse squeezing of the optical lens barrel, and the return spring 18 is in a compressed state. As the moving frame 6 continues to move, the polishing roller 8 on the moving frame 6 will gradually be inserted into the inner wall of the optical lens barrel, and the polishing motor 7 drives the rotation of the polishing roller 8 to perform a polishing operation on the inner wall of the optical lens barrel.

[0035] like Figures 1 to 4 As shown, a driving gear 19 is fixedly mounted on the output end of the polishing motor 7 , and a driven gear 20 is fixedly mounted on the end of the rotating rod 3 , and the driven gear 20 is meshingly connected with the driving gear 19 .

[0036] When the screw 14 is driven by the moving motor 15 to rotate in the opposite direction, the polishing roller 8 will be driven to gradually slide out of the inner wall of the optical lens barrel. At the same time, the moving frame 6 is controlled to move to the position where the driven gear 20 is meshed with the driving gear 19. The driving gear 19 is driven by the polishing motor 7 to rotate, which will drive the feed tray 4 to rotate. The topmost, polished optical lens barrel will slide out of the storage slot 5 of the feed tray 4 due to the rotation of the feed tray 4. At the same time, the optical lens barrel stored in the next storage slot 5 of the feed tray 4 will be driven to rotate to the top, thereby realizing the synchronous loading and unloading of the optical lens barrel.

[0037] like Figures 1 to 4 As shown, a polishing method using the above-mentioned automatic polishing device for the inner wall of an optical lens barrel comprises the following steps:

[0038] S1. Place several optical lens barrels inside the feeding rack 1. The gravity of the optical lens barrels will drive the optical lens barrels to gradually fall down. The optical lens barrel at the bottom will be stored inside the storage slot 5 of the feeding tray 4. At this time, the driven gear 20 and the driving gear 19 are in meshing state. The driving gear 19 is driven to rotate by the polishing motor 7. The meshing of the driven gear 20 and the driving gear 19 will drive the rotating rod 3 to rotate, and then the feeding tray 4 will be driven to rotate, and the optical lens barrel stored inside the storage slot 5 of the feeding tray 4 will be rotated to the top. At this time, the optical lens barrel at the bottom is stored inside the next storage slot 5 of the feeding tray 4 under the action of gravity.

[0039] S2, the screw 14 is driven to rotate by the moving motor 15, and the screw 14 is threadedly connected to the moving frame 6 to drive the moving frame 6 to move along the two guide rails 12 to control the polishing roller 8 to approach the optical lens barrel. At this time, the trapezoidal positioning block 9 will first contact the optical lens barrel, and the end of the optical lens barrel will be squeezed by the inclined surfaces on the two trapezoidal positioning blocks 9 to control the optical lens barrel to be positioned between the two trapezoidal positioning blocks 9. At the same time, the trapezoidal positioning block 9 will push the optical lens barrel to slide inside the storage slot 5 until the end of the optical lens barrel contacts the baffle 10. The continuous movement of the frame 6 is subjected to the reverse extrusion of the optical lens barrel, and the slide bar 17 connected to the trapezoidal positioning block 9 will slide inside the slide hole 16. At this time, the return spring 18 is in a compressed state. As the moving frame 6 continues to move, the polishing roller 8 on the moving frame 6 will gradually insert into the inner wall of the optical lens barrel. The polishing roller 8 driven by the polishing motor 7 will be used to polish the inner wall of the optical lens barrel. At the same time, through the operation of the dust suction component, the impurities polished on the inner wall of the optical lens barrel will be absorbed by the dust suction pipe 11 to ensure the cleanliness of the polishing area.

[0040] S3, then the screw rod 14 is driven to rotate in the opposite direction by the moving motor 15, which will drive the moving frame 6 to move in the opposite direction between the two guide rails 12, and the polishing roller 8 will gradually slide out of the inner wall of the optical lens barrel. In this process, the trapezoidal positioning block 9 is pushed by the return spring 18 in the compressed state to keep the trapezoidal positioning block 9 continuously squeezing the optical lens barrel to ensure that the polishing roller 8 slides out stably from the inside of the optical lens barrel. With the continuous movement of the moving frame 6, the moving frame 6 will move to the position where the driven gear 20 is meshed with the driving gear 19. At this time, the trapezoidal positioning block 9 will cancel the squeezing of the optical lens barrel, and the driving gear 19 will be driven to rotate by the polishing motor 7, which will drive the feed tray 4 to rotate. The topmost, polished optical lens barrel will slide out of the storage slot 5 of the feed tray 4 by the rotation of the feed tray 4. At the same time, the optical lens barrel stored in the next storage slot 5 of the feed tray 4 will be driven to rotate to the topmost point;

[0041] S4. Repeat the operations in S2 and S3 to polish the optical lens barrels one by one.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
