[0030] Working principle: the photovoltaic panel is placed on the surface of the workbench 1, the positioning disc 14 is tightly closed to the edge of the panel body by rotating the threaded rod 13, the position of the photovoltaic panel is fixed without deviation by locking the threaded holes 3 of the two positioning plates 2 symmetrically, the A driving motor 61 drives the A threaded lead screw 62 to rotate, and the driving frame 63 moves along the X axis horizontally; at the same time, the B driving motor 64 drives the B threaded lead screw 65 to rotate, and the moving block 66 moves along the Y axis vertically.
