Force application-adjustable manipulator and robot using same

Abstract

The invention discloses a force application-adjustable manipulator and robot using the same. The manipulator comprises a mechanical arm and a mechanical wrist; the mechanical wrist comprises a wrist shaft and a gripper; the gripper is mounted at one end of the wrist shaft; the other end of the wrist shaft is movably connected with one end of the mechanical arm; the mechanical arm comprises a trigger baffle plate; one side of the trigger baffle plate is connected with one end of the mechanical arm; and the mechanical wrist comprises a trigger sensor, a sensor mounting base, a force application spring and a force application adjusting nut. The force application-adjustable manipulator and the robot using the same can adjust the pressure of the gripper to contacted objects through the force application spring and the force application adjusting nut, so that the force application allowing range of the mechanical wrist can be adjusted according to the pressure requirements of different contacted objects.

Description

technical field [0001] The invention relates to the field of intelligent robots, in particular to a manipulator with adjustable force application and a robot using the same. Background technique [0002] With the continuous advancement of science and technology, robot technology has developed rapidly in recent years. In my country, industrial robots are more and more sought after by people, providing support for the transformation and upgrading of enterprises. However, the existing industrial robots rigidly contact the object when grasping the object. Therefore, in order to avoid excessive impact force when touching the object, the grasping speed must be reduced, thereby affecting the grasping efficiency. Especially for a robot with a suction cup gripper, the suction cup gripper needs to be pressed against the contact object with a certain amount of force when grasping, so as to establish a vacuum to suck the contact object tightly. Therefore, the robot with the suction cup...

AI Technical Summary

Problems solved by technology

Therefore, a robot with a suction cup gripper has high requirements on the contact force. If the contact force is too small, it cannot absorb the contact object, and if the contact force is too large, it will easily cause damage to the contact object.

However, the existing robots with suction cup grippers cannot control the contact force by hardware, and require software control, which is complicated to operate and is not convenient for production workers to use.
