[0022] The hot melt bracket 4 is an L-shaped bracket. The top of the hot melt bracket 4 is hinged to the top of the rotating cylinder support frame 3. One end of the rotating cylinder 15 is hinged to the rotating cylinder support frame 3 through a rotating connection part. The other end of the rotating cylinder 15 is hinged to the bottom of the rotating cylinder support frame 3. The rotating connection part includes a connecting rod 14 arranged at an angle downward at the top of the hot melt bracket 4. The end of the connecting rod 14 is connected to the end of the telescopic rod of the rotating cylinder. The hot melt bracket is driven to rotate 90° along the rotating cylinder support frame through the extension and contraction of the rotating cylinder, so that the hot melt mechanism on the hot melt bracket is perpendicular to the ground, and the wrapping film wrapped on the photovoltaic module is cut.

[0023] The hot melt bracket 4 is provided with a controller 13 for controlling the hot melt operation, the controller is provided with a control panel, and a PLC controller is provided inside the controller. The output end of the control panel is connected to the input end of the PLC controller, and the output end of the PLC controller is connected to the input end of the hot melt mechanism and the rotating cylinder.

[0024] The hot melt mechanism includes a movable plate 6 arranged on the inner side of the hot melt bracket 4. The front end of the movable plate 6 is provided with a hot fuse 8 through a hot fuse fixing bracket 7. The side end of the hot fuse fixing bracket 7 is provided with a heater 9. The heater heats the hot fuse to achieve the melting of the wrapping film. The heater is connected to the PLC controller through a wire.

[0025] A cable groove 12 is provided on the wire to protect the wire and prevent the wire from being pulled during the flipping and movement of the thermal fuse fixing frame, thereby causing damage to the wire and affecting the normal use of the thermal fuse.

[0026] A hot melt cylinder 5 is provided on the outside of the hot melt bracket 4. The telescopic rod of the hot melt cylinder 5 passes through the hot melt bracket 4 and is connected to the inner side of the movable plate 6 to push the movable plate forward. The input end of the hot melt cylinder is connected to the output end of the PLC controller.

[0027] Guide rods 11 are respectively provided on the left and right sides of the hot melt cylinder 5 , and the guide rods 11 are connected to the movable plate 6 to guide the moving position of the movable plate.

[0028] A plurality of buffer mechanisms 10 are provided between the movable plate 6 and the thermal fuse fixing frame 7 for buffering the thermal fuse to prevent the thermal fuse from being damaged by a large impact force generated when the movable plate moves forward.

[0031] When the utility model is melting the stretch film, the heater heats the heating wire, and the rotating cylinder pushes the connecting rod forward. Under the action of the rotating shaft at the top of the hot melt bracket, the hot melt bracket rotates into a vertical direction. At this time, the hot melt cylinder pushes the movable plate forward, driving the hot fuse fixing bracket to move forward, and the hot fuse contacts the stretch film to achieve the melting of the stretch film. After the melting is completed, the heater stops heating, and the hot melt cylinder drives the movable plate to return to its position backward. At the same time, the rotating cylinder retracts backward, pulling the connecting rod backward, and the hot melt bracket rotates into a horizontal direction under the action of the rotating shaft, waiting for the next melting operation.
