Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, and in particular discloses a mechanical arm component with a marking function. Background Art

[0002] A robotic arm is a highly automated and flexible mechanical device that imitates the functions of human arms and can move in multiple directions and precisely position. A robotic arm is usually composed of multiple joints and connecting rods. These joints can be rotating (similar to human arms) or moving in a straight line (similar to straightening and bending human fingers). Controlled by computer programs, the robotic arm can perform a variety of complex tasks, such as grasping, moving, assembling, welding, cutting, painting, etc.

[0003] With the development of industrialization, robotic arms are widely used, but the various parts of the existing robotic arms are different. Even if some parts have the same structure, it takes a lot of time and energy to identify the various parts on the robotic arm for installation / repair and replacement, which is not conducive to improving installation efficiency. Therefore, there is an urgent need for a long-arm portable robotic arm structure. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art that are not conducive to improving installation efficiency, the purpose of the utility model is to provide a mechanical arm assembly with a marking function.

[0005] To achieve the above-mentioned purpose, the utility model provides a mechanical arm assembly with a marking function, comprising a first joint, a second joint used in conjunction with the first joint, a first arm body used to connect the first joint and the second joint, and a second arm body arranged on the second joint, wherein an end of the second arm body away from the second joint is provided with an execution end used by the mechanical arm assembly to grasp, move, and process external components;

[0006] The first arm body and the second arm body have the same structure. A first marking layer and a second marking layer are respectively provided on the first arm body and the second arm body. The first marking layer and the second marking layer have the same shape and / or size.

[0007] Preferably, both ends of the arm body in the length direction are detachably connected with an annular body, and the annular body is used to install the arm body to the joint.

[0008] Preferably, the first joint includes a first rotating part and a second rotating part rotatably arranged on the first rotating part. The first rotating part and the second rotating part have the same structure. Rotating parts with the same structure can use the same design drawings and manufacturing processes, thereby simplifying the design and manufacturing process of the entire robotic arm. At the same time, such standardization can reduce design errors, speed up production, and improve interchangeability and ease of maintenance. Rotating parts with the same structure mean that they can be used interchangeably, which is conducive to repair and replacement of parts.

[0009] Preferably, the robotic arm assembly also includes a base for being mounted on an external base, and the first rotating part is rotatably disposed on the base. By installing a special base on the external base, the stability and safety of the entire robotic arm system during operation can be ensured. The base serves as a connection point between the robotic arm and the base, and can effectively disperse the force generated during the operation of the robotic arm, reduce vibration, provide stable support, ensure operational accuracy and reduce accidental risks.

[0010] Preferably, the first rotating part and the second rotating part include a first shell and a second shell respectively, and the first shell and the second shell are provided with coatings of the same shape and / or size and / or color. By using identification layers of the same shape, size and color, the consistency and coordination of the entire robotic arm can be visually enhanced, which not only improves the appearance texture of the robotic arm, but also reflects the professionalism and sophistication of the design, and plays a positive role in improving user trust and satisfaction.

[0011] Preferably, the first rotating part and the second rotating part respectively include a first cover and a second cover, and the first cover and the second cover are provided with identification layers of the same shape and / or size and / or color. The shell with the same identification layer supports the modular design concept of the robot arm components. This design allows the same or compatible components to be easily replaced, improves the maintainability and flexibility of the robot arm, and facilitates future upgrades and expansions.

[0012] Preferably, a first driving member for driving the first rotating part to rotate relative to the base is provided inside the first shell, and a second driving member for driving the second rotating part to rotate relative to the first rotating part is provided inside the second shell. The rotation axis of the first rotating part intersects with the rotation axis of the second rotating part. The cross-axis design can achieve more complex movements and higher flexibility, so that the robotic arm can operate in more space, improving its scope of application and functionality. At the same time, the cross-axis design can make the various parts of the robotic arm more compactly arranged, effectively reducing the space required for the equipment.

[0013] Preferably, the first shell and the second shell are also provided with identification holes for identifying the reset status of the first rotating part and the second rotating part. The identification holes can display the reset / operating status of the rotating part / mechanical arm. The identification holes are used to provide an intuitive way to display the current status (reset or operation) of the rotating part or the robotic arm. This physical indication method enables the operator to quickly identify the status of the equipment without relying on complex electronic monitoring systems or software interfaces. It is simple and convenient. At the same time, the identification holes can be used to intuitively confirm whether the robotic arm is in a safe reset state. This is especially important when performing maintenance, debugging or emergency shutdown operations, ensuring that the robotic arm can be prevented from accidental startup in the reset state, thereby protecting the safety of operators and maintenance personnel.

[0014] Preferably, the execution end is mounted on the second arm body via the third joint, and the execution end is mounted at the end of the third joint away from the second arm body. By setting the execution end at the farther end, the working radius and operating space of the robot arm can be significantly increased, so that the execution end can cover a wider working area.

[0015] Preferably, the shell and cover included in the first joint, the second joint and the third joint have the same structure and are all formed by one-piece injection molding. The first joint is the same size as the second joint and is larger than the third joint. The joint design with the same structure means that many design and production resources can be shared, such as tools, molds and manufacturing processes, which can reduce production costs and improve production efficiency. Compared with joints of the same structure but different sizes, mold / joint products of different sizes can be produced by simply adjusting the mold, which helps to adapt to different needs. One-piece injection molding also makes the shell and cover structure more stable.

[0016] The beneficial effects of the utility model are as follows: by using marking layers of the same shape, size and / or color on different arms, operators can more quickly identify and distinguish the same / similar parts of the robotic arm. When a part of the robotic arm needs maintenance or replacement, the design with the same marking can help maintenance personnel quickly and accurately identify the part that needs attention, without the need to spend time and effort to distinguish parts of different sizes / shapes that are difficult to distinguish, simplifying the maintenance and replacement process and reducing downtime. At the same time, the unified marking is not only functionally beneficial, but also can improve the appearance of the robotic arm. In certain application scenarios, such as exhibitions / demonstrations / work, the appearance of the robotic arm is equally important and can attract the attention of the audience and enhance the user experience. At the same time, through consistent markings of color or pattern, operators can more easily identify the action status and working area of ​​the robotic arm and avoid entering dangerous areas, thereby reducing safety hazards in the workplace.
