[0025] Two connecting plates 31 with compression strips 32 installed at the bottom are arranged between the two top plates 23 and symmetrically about the midline of the soldering station 1, and the compression strips 32 are arranged perpendicular to the extrusion strips 27. The connecting plates 31 are connected to the soldering station 1 through a plurality of second elastic members 34. When the photovoltaic cell panel 100 is located in the placement groove 21, the elastic member 26 is in a compressed state and the second elastic member 34 is in a stretched state.

[0026] Insert the photovoltaic panel into the placement groove through the left and right feed ports on both sides of the welding table, push inward from the bottom of the placement groove and the extrusion strip, and adjust the position of the photovoltaic panel. At this time, the extrusion strip moves down the sleeve on the outer surface of the piston rod under the elastic reverse thrust of the elastic member, so that the extrusion strip is tightly pressed on the top of the panel, so that the panel is positioned and fixed. At the same time, the elastic action of the second elastic member is used to move the connecting plate downward, so that the clamping strip contacts the two sides of the welding point of the photovoltaic panel, and is clamped to ensure that the gap between the panels is fixed.

[0047] The working principle is:

[0048] When in use, the photovoltaic panel is inserted into the placement groove through the left and right feed ports on both sides of the welding table, and pushed inward from the bottom of the placement groove and the extrusion strip. After adjusting the position of the photovoltaic panel, the extrusion strip, under the elastic reverse thrust of the elastic member, causes the sleeve to move down on the outer surface of the piston rod, thereby causing the extrusion strip to be tightly pressed on the top of the panel so that the panel is positioned and fixed. At the same time, the elastic action of the second elastic member is used to move the connecting plate downward so that the clamping strip contacts the two sides of the welding point of the photovoltaic panel, and is clamped to ensure that the gap between the panels is fixed.
