Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, specifically robotic arm components. Background Technology

[0002] Robotic arms are the most widely used automated mechanical devices in the field of robotics. They can be found in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although they vary in form, they all share a common feature: the ability to receive commands and precisely locate a point in three-dimensional (or two-dimensional) space to perform operations. Currently, in the medical field, medical instruments are commonly connected to the end effector of robotic arms. The robotic arm drives the movement of the medical instruments, making them easy to use. However, existing robotic arm components have complex internal structures, are mostly driven by motors, and have numerous and complex internal circuits. Their vertical and horizontal adjustment angles are limited. The vertical adjustment angle cannot reach 180°, and the horizontal rotation cannot reach 360° without dead angles. The overall reachable position is limited, and there are several positions that the end effector of the robotic arm cannot reach during use, causing inconvenience when using the instruments.

[0003] Therefore, robotic arm components are needed to improve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a robotic arm assembly to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A robotic arm assembly includes a lower arm and an upper arm. Mounting slots are provided at both ends of the lower and upper arms. A connecting rod is provided between the upper ends of the lower and upper arms. One end of the connecting rod is fixedly connected to the mounting slot on the lower arm, and the other end is rotatably connected to the mounting slot on the upper end of the upper arm via a hinge. A pneumatic support rod is rotatably connected inside the upper arm via a second hinge. A docking frame is provided at the end of the connecting rod near the upper arm, and a second limiting structure is provided within the docking frame. The output end of the second pneumatic support rod docks with the second limiting structure. A connector is provided at the lower end of the lower arm, and the upper end of the connector is inserted into the mounting slot at the lower end of the lower arm. The lower arm is rotatably connected to the mounting slot via a hinge. A pneumatic support rod is rotatably connected inside the lower arm via the hinge. A limiting structure is provided inside the connector. The output end of the pneumatic support rod 1 mates with the limiting structure. A base is provided at the lower end of the connector. A fixing rod is provided inside the mounting slot at the lower end of the upper arm. The output end of the pneumatic support rod 1 extends and presses against the connector, causing the lower arm and connector to tilt, allowing for angle adjustment in the vertical direction. The output end of the pneumatic support rod 2 extends and presses against one end of the connecting rod, allowing for angle adjustment in the vertical direction between the upper arm and the connecting rod. The overall adjustment range of the upper and lower arms can reach 180°, providing a wide adjustment range.

[0007] As a preferred embodiment of the present invention, the limiting structure includes a limiting post disposed inside the connector, a slider is slidably connected to the outside of the limiting post, and one end of the slider is rotatably connected to the output end of the pneumatic support rod through a hinge.

[0008] As a preferred embodiment of the present invention, the limiting structure two includes a limiting post two disposed inside the docking frame, and a slider two is slidably disposed on the outer side of the limiting post two. One end of the slider two is rotatably connected to the output end of the pneumatic support rod two through a hinge. The sliding arrangement of the slider and the limiting post facilitates the adjustment of the angle of the upper arm and the lower arm.

[0009] As a preferred embodiment of the present invention, both the second limiting post and the first limiting post are provided with adjusting bolts at one end. The adjusting bolts allow for adjustment and disassembly of the limiting posts, facilitating their use.

[0010] As a preferred embodiment of the present invention, the adjacent sides of the lower arm and the upper arm are open, and the adjacent sides of the lower arm and the upper arm are all bolted with protective covers. The protective covers can protect the cylinders inside the lower arm and the upper arm.

[0011] As a preferred embodiment of the present invention, one end of the fixing rod is fixedly connected to a docking end, and the lower end of the docking end is rotatably connected to a docking column, and the docking column is connected to an instrument. The docking column is connected to different instruments by bolts, and the rotation angle is 360°, which can realize adjustment without dead angle.

[0012] As a preferred embodiment of the present invention, a connecting seat is provided at the lower end of the base, and an annular groove is provided at the upper end of the connecting seat. A limiting ring is provided at the lower end of the base and inserted into the annular groove. The limiting ring is rotatably connected to the annular groove, thereby ensuring the rotational stability of the connecting seat.

[0013] As a preferred embodiment of the present invention, both the lower arm and the upper arm are made of 3K high-density matte carbon fiber material.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In this invention, pneumatic support rod one and pneumatic support rod two are respectively used to drive the lower arm and upper arm to adjust their angles in the vertical direction, thereby achieving 180° bending and extension of the entire robotic arm in the vertical direction. The lower end of the docking end is rotatably connected to a docking column with a rotation angle of 360°, which can achieve adjustment without dead angles and 360° rotation without dead angles in the horizontal direction. Moreover, the overall structure of the device is simple, with fewer internal circuits compared to existing robotic arms. The robotic arm can achieve 180° vertical bending and extension and 360° horizontal rotation, which allows for convenient movement during use and fewer inaccessible dead angle positions, facilitating the use of instruments and meters.
