Mechanical arm with collision preventing mechanism

Abstract

The invention discloses a mechanical arm with a collision preventing mechanism. The mechanical arm comprises a mobile cross beam; a rail is arranged on the movable cross beam; a mobile base is movably mounted on the rail; first collision preventing columns are respectively arranged at two ends of the mobile base, and are hollow structures; first buffer springs are arranged at the bottoms of the hollow structures; the other ends of the first buffer springs are fixedly connected with second collision preventing columns; and one ends of the second collision preventing columns are sleeved in the hollow structures of the first collision preventing columns. As the mechanical arm is provided with buffer devices on two sides of the mobile base and at two ends of the rail, the mechanical arm cannot be collided with two ends of the rail when moving on the rail, and the conditions of looseness of parts and damage of electronic elements on the mechanical arm caused by oscillation due to collision are prevented; and the collision preventing elastic columns protect the mechanical arm from being collided with other parts during rotating, so that the parts of the mechanical arm are effectively protected, and the working life of the mechanical arm is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a mechanical arm with an anti-collision mechanism. Background technique [0002] The robotic arm is a high-precision, high-speed dispensing robot. Corresponding to small batch production mode, improve production efficiency. In addition to dispensing work, it can handle various tasks such as UV irradiation, parts placement, screw locking, and circuit board cutting. [0003] With the development of science and technology, mechanical arms are applied to various enterprises to improve production efficiency. The mechanical arms in some enterprises need to perform back and forth operations on the assembly line with high frequency and fast operation speed. In this state, the manipulator is easy to collide with the track, causing damage to the electronic components inside the manipulator and loosening of the connection mechanism, which not only causes safety hazards in the prod...

[0003] With the development of science and technology, mechanical arms are applied to various enterprises to improve production efficiency. The mechanical arms in some enterprises need to perform back and forth operations on the assembly line with high frequency and fast operation speed. In this state, the manipulator is easy to collide with the track, causing damage to the electronic components inside the manipulator and loosening of the connection mechanism, which not only causes safety hazards in the production process, but also shortens the working life of the manipulator. A mechanical arm with an anti-collision mechanism to solve the above problems
