Mechanical arm machining part placing device and grabbing method

Abstract

The invention discloses a mechanical arm machining part containing device which comprises a mechanical arm, a material frame tray, a telescopic assembly and a posture detector used for detecting the inclination angle of the material frame tray, the material frame tray is provided with a containing groove, the telescopic assembly drives the inclination angle of the material frame tray, and the posture detector is used for detecting the inclination angle of the material frame tray. The posture detector sends detected angle signals to the mechanical arm, and the mechanical arm obtains the coordinates of the machined parts in all the storage grooves in the material frame tray according to angle information. According to the mechanical arm machining part containing device and the grabbing method, the coordinates of the machining parts in all the containing grooves in the material frame tray are obtained through the mechanical arm according to angle information, the spherical parts are consistently located at the positions below the containing grooves under the gravity effect in the inclined state, and the machining precision of the spherical parts is improved. According to the coordinate of each spherical part, the machined part can be accurately grabbed, the grabbing accuracy of the mechanical arm is improved, the machining efficiency is high, a visual positioning system does not need to be installed, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of manipulator processing, in particular to a device for placing parts processed by a manipulator and a grabbing method. Background technique [0002] Robots are used to grab and process parts and are more and more widely used in the field of factory automation. Some parts are of different sizes, and the robot arm cannot pick up materials through fixed coordinates. In order to ensure the success rate of grabbing, some manipulators are equipped with a vision system to ensure the success rate of grabbing, some are fixed by mechanical pressing mechanisms, and some are manually placed to ensure the success rate of picking up materials by the robotic arm. [0003] The above other methods can fix the position of the parts to improve the success rate of grasping, but the cost of the vision system is high, the structure of the mechanical pressing mechanism is complicated, and the efficiency of the manual method is l...
