Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a dual-segment dual-arm robotic arm with noise reduction function. Background Technology

[0002] A robotic arm is an automated device that mimics certain movements and functions of a human hand and arm to grasp, move objects, or manipulate tools according to a fixed program. Its key feature is that it can be programmed to perform various pre-defined tasks, and its design and performance combine the advantages of both human and robotic arms.

[0003] During horizontal movement, the dual-arm robotic arm will slide and rub against the guide rail. Over time, the lubricating oil on the guide rail will be lost due to friction. At this time, noise will be generated during the movement of the dual-arm robotic arm. It is very troublesome to manually apply lubricant frequently to reduce the movement noise. Therefore, a dual-section dual-arm robotic arm with noise reduction function is needed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems raised by the prior art by proposing a dual-section, dual-arm robotic arm with noise reduction function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dual-section, dual-arm robotic arm with noise reduction function includes a control cabinet. A guide rail is fixedly mounted on one side of the control cabinet. A carriage is slidably connected to the upper surface of the guide rail. A support plate is fixedly connected to one side of the carriage. A first permanent magnet synchronous motor is fixedly connected to the surface of the guide rail. A threaded shaft is fixedly connected to the output end of the first permanent magnet synchronous motor. One end of the threaded shaft is rotatably connected to the surface of the guide rail. A ball bearing sleeve is fixedly connected to the inner wall of the carriage. The ball bearing sleeve is fitted onto the surface of the threaded shaft. A control panel is fixedly connected to the surface of the control cabinet. A noise-reducing moving clamping mechanism is provided on the surface of the support plate.

[0006] Preferably, the noise reduction moving clamping mechanism includes a second permanent magnet synchronous motor fixedly connected to the surface of the support plate, and a rotating rod fixedly connected to the output end of the second permanent magnet synchronous motor, wherein a spiral groove is formed on the surface of the rotating rod.

[0007] Furthermore, a pair of L-shaped plates are slidably connected to the inner wall of the support plate. A first dustproof plate is fixedly connected to the surface of one of the L-shaped plates, and a second dustproof plate is fixedly connected to the surface of the other L-shaped plate. The lower surfaces of the second dustproof plate and the first dustproof plate are both in contact with the upper surface of the support plate, and the upper surface of the first dustproof plate is in contact with the inner surface of the second dustproof plate.

[0008] Preferably, a convex shaft is fixedly connected to the surface of each pair of L-shaped plates, one end of the convex shaft extends into the interior of the spiral groove, and a feed pipe is fixedly connected to the inner wall of the support plate, with a sealing cap installed at the top of the feed pipe.

[0009] Furthermore, an electric telescopic rod is fixedly connected to the upper surface of each pair of L-shaped plates. The output end of the electric telescopic rod passes through the lower surface of the L-shaped plate and is fixedly connected to a positioning plate. A third permanent magnet synchronous motor is fixedly connected to the surface of the positioning plate.

[0010] Preferably, the output end of the third permanent magnet synchronous motor is fixedly connected to a first gear, the inner wall of the positioning plate is rotatably connected to a second gear, the first gear and the second gear mesh, the surfaces of the first gear and the second gear are fixedly connected to a connecting plate, the inner wall of the positioning plate is rotatably connected to a connecting rod, and one end of the connecting plate and the connecting rod are rotatably connected to the same gripper.

[0011] The beneficial effects of this utility model are as follows: The rotating rod drives the spiral groove to rotate, which in turn drives the convex shaft, causing the positioning plate to slide within the support plate. During the sliding process, the pair of positioning plates cause the first and second dustproof plates to slide and adjust against each other, maintaining the seal of the lubricating oil inside the support plate. This prevents the lubricating oil from being disturbed by external dust, reduces evaporation and loss, increases service life, and reduces replacement frequency. The rotating threaded shaft, in conjunction with the ball sleeve, reduces the contact area, thereby reducing the noise of the slide carriage. At the same time, the rotor of the permanent magnet synchronous motor has no windings, brushes, or commutators, thus reducing mechanical noise. Attached Figure Description

[0018] By setting a second permanent magnet synchronous motor 7, the rotating rod 21 is driven to rotate, and by setting a spiral groove 22, the convex shaft 23 is driven to move under force.

[0019] In this utility model, reference is made to Figure 4 and Figure 6 A pair of L-shaped plates 19 are slidably connected to the inner wall of the support plate 5. A first dustproof plate 18 is fixedly connected to the surface of one L-shaped plate 19, and a second dustproof plate 20 is fixedly connected to the surface of the other L-shaped plate 19. The lower surfaces of the second dustproof plate 20 and the first dustproof plate 18 are both in contact with the upper surface of the support plate 5, and the upper surface of the first dustproof plate 18 is in contact with the inner surface of the second dustproof plate 20.

[0020] By setting the first dustproof plate 18 and the second dustproof plate 20, the lubricating oil inside the support plate 5 is sealed and protected, so that the lubricating oil is not affected by external dust, while reducing evaporation and loss, increasing service life and reducing replacement frequency.

[0021] In this utility model, reference is made to Figure 4 A pair of L-shaped plates 19 are fixedly connected to a convex shaft 23. One end of the convex shaft 23 extends into the interior of the spiral groove 22. A feed pipe 24 is fixedly connected to the inner wall of the support plate 5.

[0027] Working principle: In use, the first permanent magnet synchronous motor 16 is started, driving the threaded shaft 4 to rotate. The threaded shaft 4 drives the slide 6 and the support plate 5 to slide together through the ball sleeve 25.
