The pressing device 8 is used to fix the interconnecting strips on the insulating film and the pressing device 8 is used to convey the virtual line. The pressing device 8 applies pressure to the interconnecting strips heated to a certain temperature so that it can fit tightly on the insulating film. The insulating film is generally a soft non-conductive film. The control box 12 is communicated with the pressing device 8. The control box 12 is used to control the working state of the pressing device 8. The pressing device 8 can also convey the virtual line to provide power for the entire manufacturing process, thereby achieving the purpose of automated production of virtual lines.

[0031] In addition, according to actual working conditions, the heating device can also be arranged below the distance adjusting device, so that the heating device can heat the interconnecting strips in the distance adjusting device.

[0032] Furthermore, it also includes an interconnection bar guiding device and an insulating film guiding device; the interconnection bar guiding device and the insulating film guiding device are fixedly arranged on the frame 1, the interconnection bar guiding device is arranged between the upper support 2 and the distance adjusting device, the interconnection bar guiding device is used to guide the interconnection bar from the interconnection bar material roll to the distance adjusting device, the insulating film guiding device is fixedly arranged between the lower support 3 and the pressing device 8, the insulating film guiding device is used to guide the insulating film to the pressing device 8, the interconnection bar guiding device can also be used to adjust the tension when transmitting the interconnection bar to avoid the interconnection bar from being broken due to uneven force on the interconnection bar.

[0033] Furthermore, it also includes a cutting device 11, which is arranged at one end of the working plane away from the pressing device 8. The cutting device 11 is used to cut the virtual line.

[0036] A compressed air valve and a temperature sensor are provided in the bellows. The temperature sensor can detect the temperature in the bellows. The air source is used to provide the compressed air valve with air source. After the air is compressed by the compressed air valve, the temperature of the gas rises. After the heated gas is discharged from the air outlet of the hot air roller 7, the heat is transferred to the interconnection strip, thereby achieving the effect of heating the interconnection strip. The air outlet of the bellows and the end of the hot air roller 7 without the air outlet are connected through a hose.
