[0002] Optical components are the basic components of an optical system, mainly including glass lenses and various optical lenses. When producing optical components, a manipulator is needed for feeding. Compared with manual feeding, it is more accurate. At the same time, when an optical component is picked up by a manipulator, positioning is required to ensure the accuracy and stability of grasping. Positioning can ensure that the manipulator has high precision when grasping and placing optical components, and avoid damage or functional failure caused by position deviation.

[0003] For example, a rapid positioning structure for optical components with the publication number of CN218397706U in the prior art; by setting a spring between the sliding groove and the slider, it can better make the moving arc-shaped clamp and the fixed arc-shaped clamp clamp the outside of the optical component body under the spring's resilience, and thus better apply to optical component bodies with different diameters for use; however, in actual use, during the grasping work of the manipulator, although the above positioning structure meets the positioning effect, it needs to overcome the elastic force of the spring. For optical components, the friction force at the edge position is likely to cause scratches, and the optical components need to be manually placed between the two fixed arc-shaped clamps, and continuous and stable conveying cannot be carried out.

[0021] As shown by Figures 1-4 , it relates to a rapid positioning structure for optical component processing, including a conveying frame 1. Two parallel idler rollers 2 are rotatably connected inside the conveying frame 1. The outer walls of the two parallel idler rollers 2 are sleeved with the same conveyor belt 3. The conveyor belt 3 rotates with the parallel idler rollers 2 through tension and friction.

[0022] An installation plate is fixedly connected to the outer wall of the conveying frame 1. A first motor 4 is fixedly connected to the top of the installation plate. A sliding hole is opened on the outer wall of the conveying frame 1. The inner wall of the sliding hole is rotatably connected to the outer wall of the output shaft of the first motor 4. One end of the output shaft of the first motor 4 is fixedly connected to one end of one of the parallel idler rollers 2.

[0023] A U-shaped bottom frame 5 is fixedly connected to the bottom of the conveying frame 1. The bottom of the conveying frame 1 is fixedly communicated with an equipment frame 6. A second motor 7 is fixedly connected inside the equipment frame 6. The second motor 7 uses an existing servo motor. The conveying frame 1 is supported by the U-shaped bottom frame 5 and the equipment frame 6. An opening and closing door is hinged to the outer wall of the equipment frame 6.

[0024] The inner wall of the equipment frame 6 is provided with a driving mechanism. The driving mechanism includes a driving rod 8. The top of the output shaft of the second motor 7 is fixedly connected to the bottom of the driving rod 8. When the second motor 7 operates, it drives the driving rod 8 to rotate. The top of the driving rod 8 is rotatably connected to two driven rods 9 through existing bearings. The tops of the two driven rods 9 are rotatably connected to vertical rods 10 through existing bearings. The tops of the two vertical rods 10 are fixedly connected with sliding plates 11.

[0025] A moving mechanism is arranged inside the equipment frame 6. The moving mechanism includes two guide rods 12. Two through holes are respectively formed in the outer walls of the two sliding plates 11. The four through holes are grouped in pairs and are respectively slidably connected to the outer walls of the two guide rods 12. When the sliding plates 11 move, they are assisted in moving through the two guide rods 12 and the four through holes. One end of each of the two guide rods 12 is fixedly connected to the inside of the equipment frame 6. A baffle 13 is fixedly connected to the inside of the conveying frame 1.

[0026] A positioning mechanism is arranged inside the conveying frame 1. The positioning mechanism includes four circular positioning columns 17. A plurality of electric rollers 14 are rotatably connected to the inside of the conveying frame 1. Two support rods 15 are fixedly connected to the tops of the two sliding plates 11. Threaded long holes are respectively formed in the tops of the four support rods 15. The inner walls of the four threaded long holes are respectively threadedly connected with threaded rods 16. The tops of the four threaded rods 16 are respectively fixedly connected to the bottoms of the four circular positioning columns 17. The circular positioning columns 17 are made of Teflon material, having certain elasticity and corrosion resistance. And the circular positioning columns 17 can rotate and move up and down in the threaded long holes through the threaded rods 16 to change the height of the circular positioning columns 17 and perform maintenance on them.

[0027] Working principle: When in use, a plurality of electric rollers 14 operate, and the first motor 4 operates to drive one of the parallel rollers 2 to rotate. One of the parallel rollers 2 rotates to drive the other parallel roller 2 to rotate through the conveyor belt 3, realizing the sequential conveying of a plurality of optical components. And there is a large spacing between the optical components, which is convenient for subsequent sequential positioning. When the optical component in the front left is conveyed to the outer wall of the plurality of electric rollers 14, the plurality of electric rollers 14 drive it to move close to the position of the baffle 13. At this time, the second motor 7 operates to drive the driving rod 8 to rotate. The rotation of the driving rod 8 drives the two driven rods 9 and the two vertical rods 10 to rotate relatively. The relative rotation of the two vertical rods 10 drives the two sliding plates 11 to move relatively along the guide rods 12. The relative movement of the two sliding plates 11 drives the four support rods 15 and the four threaded rods 16 to move relatively, so that the four circular positioning columns 17 move relatively in pairs to clamp and position the optical component. And after positioning, the electric rollers 14 stop operating, and the output shaft of the second motor 7 reverses to drive the four circular positioning columns 17 to reset, and then it is taken by an existing mechanical gripper.

[0028] It should be noted that in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the first motor 4, the second motor 7, and the electric roller 14, which is convenient for controlling the overall operation.
