Solar panel cutting unit

A solar panel cutting unit comprising:

• a frame;
• a transport roller unit provided at the frame and configured to transport a solar panel in a first direction which is a horizontal direction, the solar panel having a glass plate, an adhesive layer, a solar cell layer, and a backsheet layer stacked sequentially;
• a heating unit configured to heat the solar panel transported by the transport roller unit;
• a pair of pressurization roller units configured to pressurize and transport the solar panel transported by the transport roller unit;
• a trimmer unit configured to move in a second direction which is horizontal direction and is perpendicular to the first direction and remove the backsheet layer, the solar cell layer, and the adhesive layer at a leading part of the solar panel which passes between the pressurization roller units;
• a peeling unit configured to insert a blade into the adhesive layer of the solar panel passing by the trimmer unit and remove a flexible film to which the solar cell layer and the backsheet layer is adhered;
• and
• a collection roller configured to collect the flexible film peeled by the peeling unit,
• wherein the trimmer unit has a dovetail vane, of which a lower part is larger in diameter than an upper part and which is configured to rotate, move in the second direction, and form an undercut portion in the solar panel.
