[0022] Preferably, the manipulator 2 uses a 2-meter arm span six-axis industrial robot of the prior art to achieve multi-angle and all-round movement. There are three processing stations 1. The manipulator 2 is first installed and fixed, and then the three processing stations 1 are arranged around the circumference of the manipulator 2. The clamping cylinder 13 is correspondingly installed on the frame 11, and the operating safety protection range of the manipulator 2 is set. A safety light curtain, i.e., a photoelectric protector, is installed at each processing station 1 to effectively protect the personal safety of the operator. Control buttons such as start and pause are connected to each processing station 1, and the grinding trajectory teaching program, the three-station switching call program and the safety door locking setting of each processing station 1 are compiled. First, the first bent frame of the TV is placed in the material storage groove 12, and the clamping cylinder 13 drives the clamping head 14 to clamp and fix the position of the first bent frame of the TV, so that the first bent frame of the TV can be positioned and clamped on the first processing station 1, and then the manipulator 2 is started to run automatically, and the grinder 3 is started by the manipulator 2 to automatically grind and trim the first bent frame of the TV. At the same time , according to the above operating steps, the second TV bent frame is positioned and clamped on the second processing station 1. After the first TV bent frame completes the automatic grinding and corner trimming process, the robot 2 rotates to the second processing station 1 and automatically grinds and trims the second TV bent frame. At this time, the first TV bent frame can be released and clamped and smoothly taken out, and then the next TV bent frame is re-clamped to wait for processing.
