Mechanical arm

Abstract

The invention relates to a mechanical arm, which comprises an arm having a first pivot part, a fixing piece fixedly connected with one end of the arm, a sliding piece movably arranged on the fixing piece, a stopping piece fixedly connected with the sliding piece and used for limiting the stroke of the sliding piece, a connecting piece fixedly connected with the sliding piece, a wrist part having a second pivot part pivoted to the connecting piece, and a third pivot part, and a driving device having a body and an extending section, wherein the body is pivoted to the first pivot part, and the extending section is pivoted to the third pivot part of the wrist part. The fixing piece, the sliding piece, the stopping piece, the connecting piece and the wrist part are matched with the driving device to achieve the dual operation effect of movement and swinging, so the production cost is reduced.

Description

technical field [0001] The present invention is related to a robot, in particular to a structure of a mechanical arm. Background technique [0002] With the advancement of robot technology, unmanned chemical factories are no longer a distant dream. In robotics technology, especially robotic arms, have long been used in many automated factories, such as Japanese Patent Application Laid-Open No. 11-77566, which is a robotic arm used in liquid crystal panel factories to transport glass substrates. The end of the robotic arm can make Movements such as lifting, swinging, and turning left and right are used to easily pick up glass substrates. However, it is an indisputable fact that many servo motors are required to produce complex movements, resulting in high manufacturing costs for the robotic arm. This is not conducive to the large-scale use of robotic arms in factories. . Moreover, in some situations that only need to move and swing, such as loading and unloading operations ...

Problems solved by technology

In robotics technology, especially robotic arms, have long been used in many automated factories, such as Japanese Patent Application Laid-Open No. 11-77566, which is a robotic arm used in liquid crystal panel factories to transport glass substrates. The end of the robotic arm can make Movements such as lifting, swinging, and turning left and right are used to easily pick up glass substrates. However, it is an indisputable fact that many servo motors are required to produce complex movements, resulting in high manufacturing costs for the robotic arm. This is not conducive to the large-scale use of robotic arms in factories.

Moreover, in some situations that only need to move and swing, such as loading and unloading operations on processing machines, using the aforementioned robotic arm is quite uneconomical for the factory, and there will be a problem of high cost

[0003] In order to solve the problem of high cost caused by the use of known robotic arms in the aforementioned simple operation situation, it is necessary to improve the current robotic arm by reducing the design direction of the servo motor, so as to meet the needs of some robotic arms that only need to move and swing
