[0038] The workflow of the present invention is:

[0039] First, the copper bar 8 without film is manually placed on the copper bar fixture on the material discharging platform 4. The placement slot 44 and the movable clamp block 45 form a placement space for the copper bar 8. The distance between the movable clamp block 45 and the fixed clamp block 43 can be adjusted by setting the fixing bolt 47 and the slot 46, so as to facilitate adjustment according to different types of copper bars 8. The clamping mechanism 6 is moved to one side of the copper bar fixture by the manipulator 5, and the opening and closing of the clamping arm 63 is controlled by the first air claw 62. When the two clamping arms 63 are closed, the copper bar 8 without film is clamped and fixed. The manipulator 5 removes the copper bar 8 without film, and then moves the copper bar 8 to the center of the mounting ring 709 and places it above the two pads 720. One end of the insulating film passes through the four guide rings 711 in sequence, and then passes through the top of the two pads 720 and passes through the cutting saw blade 718 and is set between the two shear arms 717. The insulating film is between the copper bar 8 and the pad 720. The manipulator 5 presses the copper bar 8 downward, and the insulating film moves downward at the same time. Due to the elasticity of the pad 720, the insulating film is attached to the copper bar 8. The manipulator 5 moves the copper bar 8 up to the center of the mounting ring 709. The film cutting mechanism is controlled by the air compressor and the driving unit 722 to move right along the slide rail 721 and the guide block 723 and exit the mounting ring 709; at the same time, the motor 705 is started, and the turntable 703 is driven to rotate by the driven wheel 704 and the driving wheel, and the insulating film is wound around the copper bar 8. At the same time, the rotation of the turntable 703 is detected by the positioning rod 706 and the sensor 707. For example, the manipulator 5 feeds the copper bar 8 to the right by the width of the insulating film for each rotation to achieve the winding of the insulating film. After the winding is completed, the manipulator 5 moves the copper bar 8 back by one end to the right side of the shear arm 717, and then the film cutting mechanism moves to the left and extends out to cut the insulating film through the second air claw 716, the shear arm 717 and the cutting saw 718. The manipulator places the wrapped copper bar 8 on the discharge platform 4, and takes out another unwrapped copper bar 8 for wrapping.
