DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] The circular optical lens trimming fixture of the utility model is as follows Figure 1 and Figure 2 As shown, it includes a centering robot assembly, an upper suction cup assembly and a lower suction cup assembly.

[0028] The centering robot assembly is used to center the circular optical lens and transfer the circular optical lens between the upper suction cup assembly and the lower suction cup assembly, so that the upper suction cup assembly and the lower suction cup assembly can clamp and fix the circular optical lens. The centering robot assembly specifically includes a centering robot 1, and the centering robot 1 is connected to a feeding drive mechanism that drives the centering robot 1 to move to the bottom of the upper suction cup assembly.

[0029] like Figure 2 As shown, the centering robot 1 includes a vertical support sleeve 11, in which a second telescopic drive mechanism 12 is arranged, the second telescopic drive mechanism 12 is connected to a lifting shaft 13, the lifting shaft 13 is connected to at least three clamping rods 14, the clamping rod 14 has a connecting section and a clamping section, the connecting section is hinged to the lifting shaft 13, the clamping section is located on the outer wall of the support sleeve 11, and the upper end of the clamping section extends to the top of the support sleeve 11, and the middle part of the connecting section is hinged to the support sleeve 11.

[0030] The outer diameter of the support sleeve 11 is smaller than the diameter of the circular optical lens, ensuring that the circular optical lens can be placed flat on the upper end surface of the support sleeve 11, and the edge of the circular optical lens exceeds the edge of the upper end surface of the support sleeve 11. The second telescopic drive mechanism 12 is used to drive the lifting shaft 13 to lift and lower, and the clamping rod 14 is used to clamp and center the optical lens. The clamping rod 14 can be specifically 3 or 4, and multiple clamping rods 14 are evenly distributed with the lifting shaft 13 as the center, and the lifting shaft 13 is coaxially arranged with the support sleeve 11. When the second telescopic drive mechanism 12 drives the lifting shaft 13 to move downward, since the connecting section of the clamping rod 14 is hinged with the support sleeve 11, the lifting shaft 13 will pull each clamping rod 14 to rotate synchronously, and the upper end of the clamping rod 14 rotates toward the center line direction of the support sleeve 11, so that the clamping section of the clamping rod 14 can contact the edge of the optical lens. Under the action of multiple clamping rods 14, the center position of the optical lens can be adjusted so that the center line of the optical lens coincides with the center line of the support sleeve 11, and the centering of the optical lens is achieved. The second telescopic driving mechanism 12 can be a cylinder, a hydraulic cylinder, a linear motor or the like.

[0031] The feeding drive mechanism is used to transport the centering robot 1 and the centered optical lens to the bottom of the upper suction cup assembly, so that the upper suction cup assembly can absorb the optical lens. The feeding drive mechanism specifically includes a support frame 7, a horizontal telescopic arm 8 is provided on the top of the support frame 7, and the centering robot 1 is arranged at one end of the telescopic arm 8 away from the support frame 7. The support frame 7 is vertically arranged to support the telescopic arm 8. The telescopic arm 8 can be telescopic, and when it is telescopic, it can drive the centering robot 1 to translate, so that the optical lens on the centering robot 1 moves to the bottom of the upper suction cup assembly.

[0032] The telescopic arm 8 can adopt various existing telescopic columns. Preferably, the telescopic arm 8 includes a fixed sleeve 81 and a movable rod 82. The fixed sleeve 81 is fixedly mounted on the support frame 7. One end of the movable rod 82 is located in the fixed sleeve 81 and slidably cooperates with the fixed sleeve 81, and the movable rod 82 is connected to a first telescopic driving mechanism 83. The end of the fixed sleeve 81 is fixed on the support frame 7. In order to improve the structural strength of the fixed sleeve 81, an inclined support column can be provided between the fixed sleeve 81 and the support frame 7. The first telescopic driving mechanism 83 can adopt equipment such as a hydraulic cylinder or a pneumatic cylinder. The hydraulic cylinder or the pneumatic cylinder is fixedly mounted on the support frame 7, and the piston rod of the hydraulic cylinder or the pneumatic cylinder extends into the fixed sleeve 81 and is fixedly connected to the movable rod 82.

[0033] The upper suction cup assembly specifically includes an upper connecting column 2, the lower end of which is provided with an upper suction cup 21, and the upper end of which is connected with a lifting mechanism 3. The lower suction cup assembly specifically includes a reduction motor 4, the reduction motor 4 is connected with a vertical shaft 5, and the upper end of the shaft 5 is provided with a lower suction cup 6.

[0034] The maximum outer diameter of the upper suction cup 21 and the lower suction cup 6 is smaller than the outer diameter of the optical lens. The upper suction cup 21 can suck the upper surface of the optical lens, and the lower suction cup 6 can suck the lower surface of the optical lens. The upper suction cup 21 and the lower suction cup 6 cooperate to clamp and fix the optical lens. Specifically, when the centering manipulator 1 drives the optical lens to move below the upper suction cup assembly, the lifting mechanism 3 pushes the upper connecting column 2 and the upper suction cup 21 to move downward until the upper suction cup 21 contacts the optical lens and sucks the optical lens, and then the feeding drive mechanism drives the centering manipulator 1 back to the initial position, and the lifting mechanism 3 continues to push the upper connecting column 2, the upper suction cup 21 and the optical lens to move downward. When the optical lens contacts the lower suction cup 6, the lifting mechanism 3 provides appropriate pressure to ensure that the upper suction cup 21 and the lower suction cup 6 stably position the optical lens. The reduction motor 4 is used to drive the rotating shaft 5 and the lower suction cup 6 to rotate. When the lower suction cup 6 rotates, the optical lens is driven to rotate under the action of static friction, so as to grind and trim the entire edge of the optical lens.

[0035] When the centering robot 1 moves to the bottom of the upper suction cup assembly, it ensures that the support sleeve 11, the upper connecting column 2 and the rotating shaft 5 are coaxial.

[0036] The utility model can use the centering manipulator 1 for automatic centering, and after centering, the optical lens is transferred to the bottom of the upper suction cup 21 to realize loading, without manual centering, and the operation is more convenient and labor-saving.

[0037] The upper connecting column 2 can be directly connected to the lifting mechanism 3, but when the optical lens rotates, the upper suction cup 21 and the upper connecting column 2 will also rotate with the optical lens. In order to prevent the upper connecting column 2 from hindering the rotation movement of the upper connecting column 2, the utility model provides a connecting frame 31, and the connecting frame 31 is fixedly connected to the lower end of the lifting mechanism 3. The upper connecting column 2 is installed on the connecting frame 31 through a thrust ball bearing to reduce the rotation resistance of the upper connecting column 2.

[0038] The lifting mechanism 3 adopts a hydraulic cylinder, and can also be a pneumatic cylinder or other equipment.

[0039] In order to improve the positioning stability of the upper suction cup 21 and the lower suction cup 6 on the optical lens, the upper suction cup 21 and the lower suction cup 6 are connected to the suction mechanism 10 through the air pipe 9. The air pipe 9 adopts a hose, and the suction mechanism 10 can adopt equipment such as an air pump. When the upper suction cup 21 contacts the optical lens, the suction mechanism 10 sucks air, so that negative pressure is generated in the upper suction cup 21, thereby sucking the optical lens. When the optical lens moves to the lower suction cup 6, the suction mechanism 10 sucks air, so that negative pressure is generated in the lower suction cup 6, and the optical lens is positioned simultaneously by pressure and suction.

[0040] The trimming device of the utility model is as follows: Figure 3 As shown, it includes a base 100, on which a grinding mechanism and Figure 1 and Figure 2 The round optical lens trimming fixture shown.

[0041] The grinding mechanism is connected to a grinding drive mechanism 110 that drives the grinding mechanism to move toward the upper suction cup assembly and the lower suction cup assembly. After the upper suction cup 21 and the lower suction cup 6 stably clamp the optical lens, the grinding drive mechanism 110 pushes the grinding mechanism to move to the optical lens, so that the grinding mechanism grinds and trims the edge of the optical lens.

[0042] The grinding mechanism specifically includes a slide 120, on which a grinding motor 130 is disposed, and a grinding head 140 is disposed on the main shaft of the grinding motor 130. A slide rail 150 is disposed on the base 100, on which the slide 120 is disposed and slidably cooperates, and the grinding drive mechanism 110 is a hydraulic cylinder connected to the slide 120. The slide rail 150 plays a guiding and positioning role, ensuring that the slide 120 moves stably and linearly. When the grinding drive mechanism 110 pushes the slide 120 to move, the slide 120 drives the grinding motor 130 and the grinding head 140 to move synchronously. When the grinding head 140 contacts the edge of the optical lens, the slide 120 stops moving, and then starts the grinding motor 130 and the reduction motor 4. The grinding motor 130 drives the grinding head 140 to rotate to grind the edge of the optical lens. At the same time, the reduction motor 4 drives the optical lens to rotate, so that the grinding head 140 grinds the entire edge of the optical lens.

[0043] After the grinding is completed, the grinding motor 130 and the reduction motor 4 stop running, and the grinding drive mechanism 110 drives the slide 120 back to the initial position. At the same time, the suction mechanism 10 stops sucking air and blows air into the upper suction cup 21 to release the suction force of the upper suction cup 21 on the optical lens, and uses the lifting mechanism 3 to drive the upper suction cup 21 to move upward to the initial position. Finally, the suction mechanism 10 blows air to the lower suction cup 6 to release the suction force of the lower suction cup 6 on the optical lens, and the trimmed optical lens can be removed.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
