[0002] A single-axis, dual-arm, single-segment robot is an automated device typically used in industrial production lines for material handling, assembly, or other operations. This type of robot has one rotating axis (i.e., a single axis) and is equipped with two working arms, each capable of performing a specific task independently or collaboratively. "Single-segment" means that the robot has only one joint, which is the part containing the rotating axis.
[0003] When using existing single-axis dual-arm single-section robotic arms, since the two robotic arms perform different operations, although the collision between the robotic arms can be avoided by setting the program, the materials being gripped by the robotic arms will collide, which is inconvenient to use.

One end of the connecting rod 25 is rotatably connected to the outer surface of the fixed shaft 24. The support rod 26 is rotatably connected to the inner part of the other end of the connecting rod 25. The groove 27 is opened on both sides of the upper end of the first slider 22. The fixed post 28 is fixedly connected to both sides of the upper end of the second slider 23. The fixed nut 29 is threadedly connected to the outer surface of the fixed post 28.
[0028] The slide rail 21 is used to support and guide the first slider 22, the first slider 22 is used to support and guide the second slider 23, the second slider 23 is used to support the fixed shaft 24, the fixed shaft 24 is used to support the connecting rod 25, the support rod 26 is used to support the other end of the connecting rod 25, the slide groove 27 is used to guide the fixed post 28, the fixed post 28 is used to limit the second slider 23, and the fixing nut 29 is used to fix the fixed post 28 inside the first slider 22.
[0029] The robotic arm assembly also includes a support frame 11, a control box 12, a first robotic arm 14, and a second robotic arm 15. The control box 12 is slidably connected to the upper end of the support frame 11, and the guide rail 13 is fixedly connected to the outer side of the control box 12. The first robotic arm 14 and the second robotic arm 15 are slidably connected to the inner side of the guide rail 13.
[0030] The support frame 11 is used to support the control box 12, which is used to control the movement of the first robotic arm 14 and the second robotic arm 15. The guide rail 13 is used to support and guide the first robotic arm 14 and the second robotic arm 15.
[0031] The fixing post 28 extends upward through the slide groove 27, and the outer surface of the fixing post 28 has a threaded structure relative to the fixing nut 29.
[0032] By tightening the fixing nut 29, the fixing post 28 can be fixed inside the slide groove 27.
[0033] The second slider 23 has an I-shaped structure, and the upper end of the second slider 23 is located at the upper end of the first slider 22.
[0034] The second slider 23 can move inside the first slider 22, and the movement of the second slider 23 can drive the fixed shaft 24 to slide.
[0035] The support rod 26 is fixedly connected to the outer side of the first robotic arm 14 and the second robotic arm 15 respectively, and the upper end of the second slider 23 has an L-shaped structure.
[0036] When the first robotic arm 14 and the second robotic arm 15 move, they can drive the support rod 26 to move.
[0037] Working principle: When the first robotic arm 14 and the second robotic arm 15 slide on the upper end of the guide rail 13, the spacing of the second slider 23 is adjusted according to the size of the material, so that the second slider 23 slides inside the first slider 22. The movement of the second slider 23 drives the fixed column 28 to slide inside the slide groove 27. When the second slider 23 moves to the desired position, the fixed column 28 is fixed inside the first slider 22 by using the fixing nut 29, so that the second slider 23 is fixed on both sides of the first slider 22. At this time, when the first robotic arm 14 and the second robotic arm 15 move, they will drive the support... The support rod 26 moves, which drives the connecting rod 25 to rotate. The rotation of the connecting rod 25 can be limited by the upper end of the second slider 23, thereby limiting the distance between the first robotic arm 14 and the second robotic arm 15. This prevents the materials held by the first robotic arm 14 and the second robotic arm 15 from colliding. At the same time, the first robotic arm 14 and the second robotic arm 15 drive the first slider 22 to slide on the upper end of the slide rail 21 through the support rod 26, the connecting rod 25, and the second slider 23, so that the minimum distance between the first robotic arm 14 and the second robotic arm 15 always remains the same.
[0038] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0039] The buffer assembly includes a guide groove 31, a movable rod 32, a baffle 33, a telescopic spring 34, and a damper 35. The guide groove 31 is located inside the upper end of the second slider 23. The movable rod 32 is slidably connected to the inside of the guide groove 31. The baffle 33 is fixedly connected to one side of the outer surface of the movable rod 32. The telescopic spring 34 is fixedly connected to the outside of the baffle 33. The damper 35 is fixedly connected to one side of the upper end of the second slider 23.
[0040] The guide groove 31 is used to guide the movable rod 32, the movable rod 32 is used to drive the baffle 33 to move, the baffle 33 is used to drive the telescopic spring 34 to compress, the telescopic spring 34 is used to deform and generate elastic force, and the damper 35 is used to limit the telescopic spring 34.
[0041] The inner side of one end of the damper 35 is fixedly connected to the outer end of the telescopic spring 34, and the baffle 33 is slidably connected to the inner side of the upper end of the second slider 23.
[0042] When the baffle 33 slides outward, it can cause the telescopic spring 34 to be compressed.
[0043] The outer end of the movable rod 32 has a hemispherical structure, and the outer end of the movable rod 32 extends outward through the guide groove 31.
[0044] The outer end of the movable rod 32 is in contact with the outer side of the connecting rod 25, and the rotation of the connecting rod 25 can drive the movable rod 32 to move.
[0045] Working principle: When the connecting rod 25 rotates under the drive of the first robotic arm 14 and the second robotic arm 15, the connecting rod 25 rotates along the fixed shaft 24. When the connecting rod 25 rotates towards the inner side of the upper end of the second slider 23, the connecting rod 25 drives the movable rod 32 to move. The movement of the movable rod 32 drives the baffle 33 to move. The baffle 33 drives the telescopic spring 34 to compress and generate elastic force, so that the telescopic spring 34 and the damper 35 buffer the movement of the movable rod 32, thereby buffering the movement of the first robotic arm 14 and the second robotic arm 15.
