[0015] The present invention has the following beneficial effects:

[0016] 1. The present invention winds the photovoltaic welding ribbon on the winding roller on one side, controls the first electric push rod to drive the second motor to move downward, so that the driving gear on the second motor passes through the notch on one side, and the driving gear is meshed with the driven gear on one side, and then starts the second motor to drive the driving gear to rotate, thereby driving the rotating shaft close to the photovoltaic welding ribbon to rotate, and further driving the cylindrical tube and the winding roller close to the photovoltaic welding ribbon to rotate, thereby completing the winding of the photovoltaic welding ribbon; after the photovoltaic welding ribbon is wound up, the photovoltaic welding ribbon is cut off, and then the first electric push rod is controlled to drive the second motor and the driving gear to move upward After reaching the initial position, the rectangular frame is then driven to rotate 180° by controlling the first motor, thereby driving the two winding rollers to rotate 180°, so that the winding roller after winding is rotated to the other side, and the unloaded winding roller rotates to the position of the photovoltaic welding tape to be wound, thereby quickly completing the rapid winding and rewinding of the photovoltaic welding tape. The setting of the two winding rollers allows the winding roller on one side to wind up the photovoltaic welding tape, and the winding roller on the other side can be replaced synchronously without affecting the winding of the winding roller that is winding up the photovoltaic welding tape, effectively avoiding the time of temporarily winding up the photovoltaic welding tape when replacing the winding roller, thereby improving the winding efficiency of the photovoltaic welding tape.

[0017] 2. The present invention controls the third motor to drive the second spur gear to rotate, so that the second spur gear drives the first spur gear to rotate, and then drives the threaded rod to rotate, so that the threaded rod drives the lifting plate to move downward, and the lifting plate drives the arc plate to move downward. When the arc plate moves downward until it contacts the winding roller, the glue in the glue storage box is injected into the arc groove through the glue guide head, so that the glue is spread on the outer wall of the winding roller through the glue guide hole, and the lifting plate is continuously controlled to move downward, so that the two arc plates move away from each other along the outer wall of the winding roller, so that the glue is evenly spread on the outer wall of the winding roller, and then the lifting plate is driven upward by the third motor, thereby driving the arc plate to move away from the winding roller. The lifting plate is driven by the third motor to move downward, and then the arc plate is driven to move toward the winding roller, so that the photovoltaic welding ribbon passes over the winding roller. The arc plate is used to make the photovoltaic welding ribbon adhere to the outer wall of the winding roller, and the photovoltaic welding ribbon is glued to the outside of the winding roller by glue. Finally, the arc plate is controlled to move upward to the initial position, and one end of the photovoltaic welding ribbon is quickly fixed on the outer wall of the winding roller, so that the photovoltaic welding ribbon can be more conveniently wound on the winding roller, thereby preventing the end of the photovoltaic welding ribbon from slipping off the outer wall of the winding roller, which affects the smoothness and tightness of the winding of the photovoltaic welding ribbon.

[0018] 3. The present invention drives the photovoltaic welding tape to move back and forth in the horizontal direction by the reciprocating movement of the guide frame in the horizontal direction, so that the photovoltaic welding tape is evenly rolled up on the winding roller, thereby ensuring the neatness and tightness of the photovoltaic welding tape after rolling up, thereby improving the rolling quality of the photovoltaic welding tape.
