A winding station 8 is arranged between the winding main disk and the clamping mechanism. A driving motor 9 is arranged on the support seat, and a winding shaft 10 is connected to the driving motor. One end of the winding shaft away from the driving motor is connected to the winding main disk, and a straightening mechanism 11 is arranged in front of the cutting mechanism.

[0022] A tape sticking mechanism 12 is also arranged on one side of the winding station. The tape sticking mechanism includes a tape sticking bottom plate 13, a tape releasing wheel 14 is arranged on the tape sticking bottom plate, a tape guiding wheel 15 is arranged on one side of the tape releasing wheel, and a tape pressing wheel 16 is arranged below the tape guiding wheel.

[0023] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the cutting mechanism includes a shear blade 17 arranged at the end of the straightening mechanism, a cutting motor 18, and a shear base 19; the shear blade includes a movable blade 20 and a fixed blade 21, the fixed blade has the same structure as the movable blade, side plates 22 are installed on the shear base, the cutting motor is installed on the side plates, the output shaft of the cutting motor is connected to the movable blade, the fixed blade is installed on the outer shell of the cutting motor, the movable blade includes a first blade body 24 connected to the output shaft of the cutting motor and a second blade body 25 away from the output shaft of the cutting motor, a plurality of unit blade bodies 41 are arranged between the first blade body and the second blade body, the first blade body, the second blade body, and the unit blade bodies are connected by an adjusting member 26, mounting grooves 27 are provided at one end of the first blade body, one end of the second blade body, and both ends of the blade unit, the blade unit includes a base 28 and a blade part 29 located on one side of the base, a sliding groove 30 is formed on the blade part, and the mounting groove is arranged on the end face of the base; a sliding blade 32 is arranged inside the sliding groove; the adjusting member includes a fixed block 33, rollers 34 connected to the fixed block are installed at both ends of the fixed block, a resistance belt 35 is wrapped outside the fixed block and the rollers, the resistance belt is at least partially arranged on both sides of the fixed block, and limiting strips 36 are installed on its outer surface. There is a great resistance when the resistance belt rotates, and the inner side surface of the resistance belt and the outer surface of the roller can adopt a frosted material.

[0024] In this embodiment, the first blade body, the second blade body, and the unit blade bodies are all made of steel, and the limiting strips are made of permanent magnetic materials such as neodymium iron boron permanent magnets. During specific operation, when the first blade body, the second blade body, or the unit blade body touches the limiting strip, they will be adsorbed together.

The winding main disc of the winding mechanism and the clamping mechanism have previously clamped an I-shaped disc. When the bus bar reaches the winding station, the drive motor of the winding mechanism starts, driving the winding shaft to rotate, so that the winding main disc drives the I-shaped disc to start winding the bus bar. At the same time, the tape sticking mechanism presses the tape pressing wheel on the bus bar with appropriate pressure, evenly sticking the tape on the surface of the bus bar to complete the tape sticking process. When the winding work is completed, the cutting motor starts, driving the cutting slider and the cutting edge to perform a cutting action, so that the cutting edge accurately cuts the bus bar. Subsequently, the clamping mechanism resets, and the I-shaped disc after cutting falls to the blanking chassis, and the empty disc is lifted to the winding bracket to continue winding.

[0029] The adjusting member is integrally placed in the installation groove, and the position of the limiting strip is adjusted by rotating the resistance band. When the first tool body, the second tool body or the unit tool body abuts against the limiting strip, the position of the adjusting sliding blade is coordinated, and then the distance between the first tool body, the second tool body and the unit tool body is adjusted. Finally, the lengths of the movable blade and the fixed blade can be adjusted.
