Electromagnetic auxiliary grabbing device

Abstract

The invention provides an electromagnetic auxiliary grabbing device. The electromagnetic auxiliary grabbing device comprises a base, a mechanical arm, an electromagnetic detector and an upper computer; the base is installed on a moving device, and the moving device drives the base to move in a multi-axis mode; the mechanical arm comprises a plurality of mechanical arms distributed on the base, each mechanical arm is composed of a driving arm and a driven arm which are connected in a hinged mode, the driving arms are installed on the base, clamping jaws are detachably installed at the tail ends of the driven arms, and electromagnets are carried on the clamping jaws; the electromagnetic detector is installed on at least one clamping jaw and connected with the electromagnets, and if the electromagnetic detector senses that an object clamped by the clamping jaw is metal, the electromagnets are conducted for auxiliary fixing; and the upper computer is connected with the moving device and the mechanical arm and used for controlling the moving device to drive the base to move and controlling the grabbing operation of the mechanical arm. The electromagnetic detector is used for detecting whether the grabbed object is metal or not, and if the grabbed object is metal, the electromagnets are started to provide auxiliary grabbing for attracting ferromagnetic substances.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an electromagnetic auxiliary grasping device. Background technique [0002] At present, in the field of manipulator grasping, most manipulators have a single grasping mode. This method is not efficient, and the work intensity is relatively high, which is likely to cause waste of resources. Although the current factory is equipped with corresponding grabbing manipulators, due to the single grabbing mode of the manipulator, it can only grab one kind of item and cannot complete the factory tasks in a short time, resulting in low factory efficiency. In addition, there is a kind of mini manipulator, which achieves the purpose of sorting items by grabbing together with multiple manipulators. However, when there are too many grasping targets, it will occupy a large amount of space, affect the layout of the factory, and thus affect the efficiency of the enterprise. [0003] In addition, the curre...

[0002] At present, in the field of manipulator grasping, most manipulators have a single grasping mode. This method is not efficient, and the work intensity is relatively high, which is easy to cause waste of resources.

Although the current factory is equipped with corresponding grabbing manipulators, due to the single grabbing mode of the manipulator, it can only grab one kind of item and cannot complete the factory tasks in a short time, resulting in low factory efficiency

In addition, there is a kind of mini manipulator, which achieves the purpose of sorting items by grasping together with multiple manipulators. However, when there are too many grasping targets, it will cause a large amount of space to be occupied, affecting the layout of the factory, thereby affecting the efficiency of the enterprise.

[0003] In addition, the current grasping logic of the manipulator is not intelligent enough. The movement of the manipulator is relatively fixed. It needs a program to set its movement path. The space layout is strictly limited. When there are many objects to be grasped, the probability of grasping failure will increase. Workers need to manually operate to grasp the target objects, and it is difficult to achieve stable grasping by manipulators.
