[0018] All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0019] Reference Figures 1-6 。

[0020] The present utility model provides an optical lens barrel clamping manipulator, which includes a support 1, an X-axis linear drive mechanism 2 arranged at the top of the support 1, a Z-axis linear drive mechanism 3 drivingly connected to the X-axis linear drive mechanism 2, and a double-headed material clamping mechanism 4. The double-headed material clamping mechanism 4 includes a first connecting member 40 drivingly connected to the Z-axis linear drive mechanism 3, a rotary cylinder 41 fixedly connected to the first connecting member 40, a second connecting member 42 drivingly connected to the rotary cylinder 41, and two pneumatic three-jaw chucks 43. The two pneumatic three-jaw chucks 43 are orthogonally arranged and are both connected to the second connecting member 42 through an elastic buffer device 5.

[0021] The working principle is as follows: when the X-axis linear drive mechanism 2 works, it can drive the double-head clamping mechanism 4 to move left and right, so as to realize the round-trip movement of the double-head clamping mechanism 4 between the processing station and the material bin. The finished product tray and the material tray are both located on the material bin. When the Z-axis linear drive mechanism 3 works, it can drive the double-head clamping mechanism 4 to move up and down, so as to realize the loading and unloading actions of the double-head clamping mechanism 4. During the loading and unloading operation, one of the pneumatic three-jaw chucks 43 takes a lens barrel to be processed from the material tray, then the double-head clamping mechanism 4 moves to the processing station, and the other pneumatic three-jaw chuck 43 removes the processed lens barrel from the processing station. The second connecting member 42 is rotated 180° by the rotating cylinder 41, so that the two pneumatic three-jaw chucks 43 exchange positions, and the lens barrel to be processed can be placed on the processing station. Then, the manipulator places the processed lens barrel on the finished product tray, which can effectively shorten the walking distance of the manipulator for loading and unloading, improve the loading and unloading efficiency, increase the output, and reduce the energy consumption of the equipment. The pneumatic three-jaw chuck 43 is connected to the second connecting member 42 through the elastic buffer device 5, which plays a buffering role during the loading and unloading process to avoid damaging the lens barrel.

[0022] Based on the above embodiment, the second connecting member 42 includes a connecting column 420 drivingly connected to the rotating cylinder 41, a connecting block 421 connected to one end of the connecting column 420, and side plates 422 respectively fixedly connected to both side surfaces of the connecting block 421. The connecting block 421 includes two vertically arranged mounting surfaces 421a. The elastic buffer device 5 includes a sliding plate 50 slidably connected between the two side plates 422, a buffer spring 51 abutted between the inner side surface of the sliding plate 50 and the mounting surface 421a, and a plurality of guide bolts 52. The sliding plate 50 is provided with a guide hole matching the guide bolts 52. The guide bolts 52 pass through the guide hole and are fixedly connected to the mounting surface 421a. The pneumatic three-jaw chuck 43 is fixedly connected to the outer side surface of the sliding plate 50. When the manipulator picks up and places the lens barrel, the force on the lens barrel will cause the buffer spring 51 to be compressed, and the sliding plate 50 will move along the guide bolts 52, playing a buffering role, reducing the force on the lens barrel when picking up and placing the lens barrel, and avoiding deformation and fracture of the lens barrel.

[0023] Based on the above embodiment, the X-axis linear drive mechanism 2 includes an X-axis slide base 20 fixedly connected to the top of the support column 1, an X-axis slide plate 21 slidably connected to the X-axis slide base 20, and a first drive motor 22 arranged on the X-axis slide plate 21. An X-axis rack 23 is arranged on the X-axis slide base 20 along its length direction, and a first gear 24 meshing with the X-axis rack 23 is arranged on the output shaft of the first drive motor 22. When the first drive motor 22 works, the X-axis slide plate 21 will move along the X-axis slide base 20, which has the advantages of simple structure, convenient maintenance, and high movement stability.

[0024] Based on the above embodiments, the Z-axis linear drive mechanism 3 includes a Z-axis slide base 30 fixedly connected to one side of the X-axis slide plate 21, a Z-axis slide plate 31 slidably connected to the Z-axis slide base 30, and a second drive motor 32 disposed on the Z-axis slide base 30. A Z-axis rack 33 is disposed on the Z-axis slide plate 31 along its length direction, and a second gear 34 meshingly connected to the Z-axis rack 33 is disposed on the output shaft of the second drive motor 32. When the second drive motor 32 operates, the Z-axis slide plate 31 will move along the Z-axis slide base 30, having the advantages of simple structure, convenient maintenance, and high movement stability.

[0025] Based on the above embodiments, the first connecting member 40 includes a horizontal plate 400 fixedly connected to the bottom end of the Z-axis slide plate 31, and an inclined plate 401 connected to one end of the horizontal plate 400 and disposed at an angle of 45° with the horizontal plane. The rotary cylinder 41 is fixedly connected to the inclined plate 401, which can make one pneumatic three-jaw chuck 43 in a horizontal state and the other pneumatic three-jaw chuck 43 in a vertical state, facilitating the assembly of the lens barrel onto the horizontal processing station seat and placing the lens barrel vertically on the tray.

[0026] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
