[0020] The double-shaft moving unit comprises a core linear motor 4 installed on the back of the right-angle frame 1, a tripod 5 installed on the moving end of the core linear motor 4, a Y-axis linear module 6 installed on one side of the outer wall of the tripod 5, and the extension line of the Y-axis linear module 6 is perpendicular to the extension line of the belt conveyor 10. A connecting arm 7 is installed on the moving end of the Y-axis linear module 6, and the height of the tripod 5, the Y-axis linear module 6, the connecting arm 7 and the plug-in connector 8 in the vertical direction is controlled by the core linear motor 4, and the Y-axis linear module 6 drives the connecting arm 7 and the plug-in connector 8 to move in the Y-axis direction, so that the plug-in connector 8 and the butt connector are plugged in.

[0021] The belt conveyor 10 comprises a belt conveying structure 1002 installed in the conveying frame 9 and a pulley driving unit 1001 installed on one end of the back of the base 2, and the pulley driving unit 1001 drives the belt conveying structure 1002 to work.

[0022] When the photovoltaic panel is placed on the belt conveying structure 1002, the belt conveying structure 1002 moves the photovoltaic panel by driving the belt conveying structure 1002 by the pulley driving unit 1001, and the speed of the belt conveyor 10 can be adjusted by the PLC control panel 3 during the process.

[0023] The plate offset structure 12 comprises two guide plates 1201 fixed on one side of the top end of the conveying frame 9 and a support shaft 1202 slidably installed in the guide plate 1201, one end of the support shaft 1202 penetrates to the outside of the guide plate 1201 and is provided with a bevel plate 1203, a positioning bolt 1204 is installed on one side of the outer wall of the support shaft 1202, one end of the positioning bolt 1204 extends to the inside of the guide plate 1201 and abuts against the outer wall of the support shaft 1202, and during the process of moving the photovoltaic panel, when the side frame of the photovoltaic panel contacts the bevel plate 1203, the bevel plate 1203 actively guides the movement of the photovoltaic panel.

[0024] The staff can manually slide the support shaft 1202 to make the support shaft 1202 drive the bevel plate 1203 to approach or move away from the electric push structure 11, so as to adjust the distance between the electric push structure 11 and the plate offset structure 12, and then the guide plate 1201 and the support shaft 1202 can be locked by the positioning bolt 1204, so as to be suitable for conveying photovoltaic panels of different widths;
