For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.
[0021] See also Figure 1-9A device for integrated repair and polishing of aspheric optical lenses comprises a substrate 1, a base 2 is mounted at equal angles on the top outer side of the substrate 1, a support seat 3 is mounted on the top of the base 2, a through groove 4 is penetrated through the top center of the support seat 3, an adjustable clamping mechanism 5 is mounted inside the through groove 4, a fixed seat 6 is mounted at the top center of the substrate 1, a repair and polishing mechanism 7 is mounted on the side of the fixed seat 6 facing the support seat 3, and a driving mechanism 8 for driving the base 2 to rotate is arranged inside the substrate 1.
[0022] like Figure 1-9 As shown, the through groove 4 includes a circular groove 401 that passes through the center of the top of the support seat 3, and a connecting groove 402 is arranged on the outer side of the circular groove 401. The circular groove 401 limits the up and down movement of the circular plate 501, and the connecting groove 402 facilitates the movement of the vertical plate 503 to clamp aspheric optical lenses of different sizes.
[0023] like Figure 1-9 As shown, the clamping mechanism 5 includes a circular plate 501 movably arranged inside the circular groove 401, and a movable movable plate 502 is installed on the outer wall of the circular plate 501 along the outer side of the connecting groove 402, and a vertical plate 503 is vertically installed on the end of the movable plate 502 away from the circular plate 501, and a clamping plate 504 is connected to the top of the vertical plate 503, and a first spring 505 is installed on the side of the vertical plate 503 away from the circular plate 501, and the other end of the first spring 505 is connected to a connecting plate 506. When clamping the aspheric optical lens, the staff places the aspheric optical lens on the top of the support seat 3, and then controls the circular plate 501 to move upward. During the upward movement of the circular plate 501, the movable plate 502 will be synchronously driven to move toward the direction of the circular plate 501, and the elastic force of the first spring 505 makes the clamping plate move toward the direction of the circular plate 501, so as to clamp and fix the aspheric optical lens, and the elastic force of the first spring 505 can clamp aspheric optical lenses of different sizes.
[0024] like Figure 1-9 As shown, a limit groove 9 is opened on the inner side of the connecting groove 402 away from the connecting plate 506, and a limit block 10 fixed to the outer side of the connecting plate 506 is installed inside the limit groove 9. The setting of the limit groove 9 and the limit block 10 ensures that the connecting plate 506 always remains in a horizontal position during the movement of the vertical plate 503, and only moves up and down synchronously with the vertical plate 503 moving up and down.
[0025] like Figure 1-9As shown, a circular oil tank 11 is provided inside the circular plate 501, and the outer side of the oil tank 11 is equidistantly connected to slots adapted to the movement of the movable plate 502. A groove 12 is provided at the top center of the base 2, and a hydraulic rod 13 is installed inside the groove 12. The top of the hydraulic rod 13 is connected to the bottom of the circular plate 501, and the outer bottom of the hydraulic rod 13 is connected to a telescopic hose 14 that penetrates into the oil tank 11. When the hydraulic rod 13 controls the circular plate 501 to move upward, negative pressure is formed when the telescopic end of the hydraulic rod 13 moves upward, and the oil in the oil tank 11 is sucked into the hydraulic rod 13 through the telescopic hose 14, and the movable plate 502 is driven to move toward the direction of the circular plate 501. When the clamping plate extends to the top of the support seat 3, all the oil in the oil tank 11 enters the hydraulic rod 13. At this time, the movable plate 502 loses its supporting force, and the elastic force of the first spring 505 will squeeze the clamping plate to clamp and fix the aspheric optical lens. At this time, the movable plate 502 will also move toward the circular plate 501, and will compress the air into the telescopic hose 14. When the hydraulic rod 13 controls the circular plate 501 to move downward, the compressed air in the telescopic hose 14 first enters the oil tank 11 to squeeze the movable plate 502 to move away from the circular plate 501, and then squeezes the oil into the oil tank 11 to make the movable plate 502 move away from the circular plate 501.
[0026] like Figure 1-9 As shown, the polishing mechanism 7 includes a rotating rod 701 rotatably connected to the outside of the fixed seat 6, and a movable groove 702 is provided at one end of the rotating rod 701 away from the fixed seat 6, and a movable rod 703 is movably connected inside the movable groove 702, and a processing tool 704 is connected to the side of the movable rod 703 away from the fixed seat 6. One end of the rotating rod 701 extends to the inside of the fixed seat 6 and a first bevel gear 705 is installed. A motor 706 is provided on the top of the fixed seat 6, and the output end of the motor 706 passes through the inside of the fixed seat 6 and is connected to a second bevel gear 707 meshing with the first bevel gear 705. The second bevel gear 707 can be controlled by the motor 706 to mesh and rotate the first bevel gear 705, and then the rotating rod 701 can be controlled to rotate. At this time, the processing tool 704 can be synchronously driven to rotate to polish the clamped aspheric optical lens.
[0027] like Figure 1-9As shown, an oil tank 15 is fixedly installed on the inner side of the fixed seat 6, and an arc tube 16 is installed on the top of the oil tank 15 and penetrates into the interior of the rotating rod 701. An inner groove 17 is opened at one end of the arc tube 16 facing the rotating rod 701, and a telescopic plate is installed in the inner groove 17. The end of the telescopic plate facing the movable rod 703 is connected with a connecting rod 18. The telescopic plate can control the movable rod 703 to move different lengths for aspheric optical lenses of different sizes, so that the processing tool 704 can polish aspheric optical lenses of different sizes synchronously, and the work efficiency is greatly improved.
[0028] like Figure 1-9 As shown, an electric rod 19 is installed at the center of the inner bottom of the fixed seat 6, and the telescopic end of the electric rod 19 penetrates into the inner side of the oil tank 15 and is connected to a top plate 20. The electric rod 19 pushes the top plate 20 upward to transport the oil inside the oil tank 15 to the inner groove 17 through the arc tube 16, and then pushes the movable rod 703 to move toward the position of the aspheric optical lens. The arc tube 16 and the rotating rod 701 are rotatably connected through a bearing.
[0029] like Figure 1-9 As shown, the telescopic plate includes a first push plate 21 arranged inside the inner groove 17, and the first push plate 21 is connected to a second spring 22 at one end facing the movable rod 703, and the other end of the second spring 22 is connected to a second push plate 23. Several groups of movable rods 703 are moved toward the direction of the aspheric optical lens at the same time. The larger the aspheric optical lens, the more contact will be made with the movable rod 703 at the corresponding position, and the other groups still need to continue moving. At this time, the first push plate 21 at the corresponding position of the stopped movable rod 703 will push the second spring 22 to move toward the position of the second push plate 23. At this time, the distance between the two is shortened, and the movement of other movable rods 703 will not be hindered during the stopping of the movable rod 703.
[0030] like Figure 1-9 As shown, the driving mechanism 8 includes a connecting rod rotatably arranged inside the base plate 1 and integrally connected to the base 2, the outer wall of the connecting rod is connected to the first pulley 801, the outer wall of the first pulley 801 is transmitted by a first transmission belt 802, and the outer wall of a group of first pulleys 801 is provided with a second transmission assembly 803 for transmission, the second transmission assembly 803 will drive a group of first pulleys 801 to rotate, and then drive other first pulleys 801 to rotate through the first transmission belt 802, so that the base 2 can rotate synchronously for polishing.
[0031] Working principle: When clamping the aspheric optical lens, the staff places the aspheric optical lens on the top of the support seat 3, and then controls the circular plate 501 to move upward. During the upward movement of the circular plate 501, the movable plate 502 will be synchronously driven to move toward the direction of the circular plate 501. The elastic force of the first spring 505 causes the clamping plate to move toward the direction of the circular plate 501, thereby clamping and fixing the aspheric optical lens. The elastic force of the first spring 505 can clamp aspheric optical lenses of different sizes. During the upward movement of the circular plate 501 controlled by the hydraulic rod 13, negative pressure will be formed when the telescopic end of the hydraulic rod 13 moves upward, and oil will be pumped into the hydraulic rod 13 through the telescopic hose 14. The oil in the liquid tank 11 is sucked into the hydraulic rod 13, which will drive the movable plate 502 to move toward the circular plate 501. When the clamping plate extends to the top of the support seat 3, the oil in the oil tank 11 all enters the hydraulic rod 13. At this time, the movable plate 502 loses its supporting force, and the elastic force of the first spring 505 will squeeze the clamping plate to clamp the aspheric optical lens. At this time, the movable plate 502 will also move toward the circular plate 501, and will compress the air into the telescopic hose 14. When the hydraulic rod 13 controls the circular plate 501 to move downward, the compressed air in the telescopic hose 14 first enters the oil tank 11 to squeeze the movable plate 502 toward The movable plate 502 moves in the direction away from the circular plate 501, and then squeezes the oil into the oil tank 11 to make the movable plate 502 move in the direction away from the circular plate 501. The motor 706 can control the second bevel gear 707 to mesh and rotate the first bevel gear 705, and then the rotating rod 701 can be controlled to rotate. At this time, the processing tool 704 can be synchronously driven to rotate to polish the clamped aspheric optical lens. The electric rod 19 pushes the top plate 20 upward to transport the oil in the oil tank 15 to the inner groove 17 through the arc tube 16, and then pushes the movable rod 703 to move toward the position of the aspheric optical lens. The telescopic plate can control the movable rod 703 to move toward the aspheric optical lens. Aspheric optical lenses of the same size can be moved to different lengths, so that the processing tool 704 can simultaneously polish aspheric optical lenses of different sizes, which greatly improves work efficiency. Several groups of movable rods 703 are set to move toward the direction of the aspheric optical lens at the same time. The larger the aspheric optical lens, the more contact will be made with the movable rod 703 at the corresponding position, and the other groups need to continue moving. At this time, the first push plate 21 at the corresponding position of the stopped movable rod 703 will push the second spring 22 to move toward the position of the second push plate 23. At this time, the distance between the two is shortened, and the movement of other movable rods 703 will not be hindered during the stopping of the movable rod 703.
