Abstract

Provided is a material edge detecting method of a tooling. A group of edge measurement sensors for detecting the edge position of a material is respectively arranged in the X-direction and the Y-direction of the tooling and includes two sensors installed at the diagonal line position of the tooling. The edge measurement sensors are photoelectric sensors, and the measurement directions and the transmitting-receiving directions of the edge measurement sensors are perpendicular to the measured edge. A robot carries the tooling to sequentially perform reciprocating motion in the X-direction and the Y-direction of the material for at least one time so as to obtain the material edge position, and a reciprocating stroke is +/-50mm-+/-100mm. The lower portion of the connecting position of the tooling and a robot flange is provided with two calibration sensors for calibrating the positions of the two groups of edge measurement sensors of the tooling. The sensors for detecting the material position is installed on the tooling and used for detecting and confirming the position of the material so as to improve the accuracy of carrying and stacking operation of the robot.

Description

technical field [0001] The invention relates to a detection method in the field of robots, in particular to a method for detecting the edge of an assembly by an end picker. Background technique [0002] In the field of robotics, visual sensors or other sensors can be installed on the fingers of the manipulator, the robot end picker or other positions to obtain information such as the position, shape, and spatial distribution of the group materials. When the visual sensor is used to detect the information of the group material, it is necessary to perform data acquisition, analysis and processing operations on the image, which will generate a large amount of calculation and may affect the detection speed. At the same time, when the size of the group is large, the measurement accuracy may be affected due to image distortion and low pixel resolution. [0003] Chinese patent CN1539604 discloses a tactile sensor and its tactile information detection method. Through the "soft cont...
