Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to a high-strength industrial robot component. Background Art

[0002] The components of industrial robots usually include the following main parts:

[0003] Robotic arm: This is the main component of an industrial robot, usually composed of a series of joints and links, used to grasp, carry or manipulate objects. The design of the robotic arm determines the robot's range of motion and carrying capacity;

[0004] Controller: The controller is the brain of the robot, responsible for processing data from sensors and controlling the movement of the robot arm and other parts. It contains processors, memory, input / output interfaces, and other electronic devices;

[0005] Sensors: Sensors are used to detect changes in the robot's surrounding environment or its own state, such as position, speed, acceleration, force, torque and other information. Common sensor types include visual sensors, touch sensors, distance sensors, etc.

[0006] Actuator: An actuator is a device that converts electrical energy into mechanical energy. It is often used to drive the joints of a robotic arm or change the position and posture of a robotic arm. Common actuators include servo motors, hydraulic cylinders, pneumatic cylinders, etc.

[0007] End effector: The end effector is installed at the end of the robot arm and is used to directly contact the work object to complete a specific task. It can be a gripper, welding gun, paint gun, laser cutting head, etc.

[0008] The rest also include the corresponding power supply system, power transmission components, various programming software, etc.

[0009] At present, between the arms of conventional industrial robots, corresponding sleeves are usually installed at the connected ends of the arms. Then, the sleeve and shaft rod of one arm are rotatably arranged as the front section, and the sleeve and shaft rod of the other arm are fixedly sleeved as the rear section. The end of the shaft rod is connected to the motor to realize the rotation of one arm relative to the other arm. However, this method does not have a reinforced structure at the active point, resulting in that when the arms rotate relative to each other for a long time, the components of the rotating structure are easily damaged and slip, which not only affects production efficiency, but also easily causes safety hazards in the production process.
