The invention relates to an automatic feeding and discharging method for a plate part electrophoresis production line, which comprises the following steps: firstly, positioning a hanger to a station table through a slide rail, and placing plate parts in a special stacking bin; images and depth information of the parts and the hanging tool are synchronously collected through an industrial depth camera and a lateral global industrial camera; carrying out preprocessing and edge detection on the image, extracting the minimum circular hole contour of the part, and carrying out angular point and straight line detection on the hanger image to identify the position of a cargo hook; 3D coordinates of the center point of the circular hole are obtained based on Hough circle transformation, the suction position is determined by combining depth information, and suction is completed through a vacuum chuck at the tail end of a six-axis mechanical arm; by comparing the angle between the side edge of the part and the cargo hook and the overlap ratio between the circular hole and the corner point of the cargo hook, the manipulator is adjusted to realize accurate placement; after each row of hanging pieces is completed, the hanging tool transversely moves by one cargo hook interval; and the hanger is turned over after a single face is completed, and the process is repeated. According to the device, automatic identification, positioning and feeding and discharging of the plate parts are achieved, and the production efficiency and electrophoresis quality consistency are improved.

This invention relates to a pipe bending method using a mobile pipe bending robot, comprising a coordinate system establishment step, a machining trajectory planning step, and a pipe bending execution step. The coordinate system establishment step includes: S11, establishing a base coordinate system; S12, establishing a robot base coordinate system; S13, establishing a robot machining coordinate system; and S14, establishing a pipe fitting coordinate system. The machining trajectory planning step includes: S21, establishing a 3D model of the pipe fitting; S22, calibrating the robot machining coordinate system based on the 3D model of the pipe fitting; and S23, calculating the pipe fitting machining parameters. The pipe bending execution step involves the machining trajectory Traj having a discontinuity point N for each bend. The robot first moves to the discontinuity point to perform the pipe bending operation, and after the bend is completed, it continues to the next trajectory segment. This invention, based on a mobile pipe bending robot, proposes a pipe bending method that improves bending accuracy, shortens overall processing time, and increases bending efficiency.
