[0076] The rotating assembly is arranged in the rotating seat 14 to achieve the function of cutting the copper foil that is pressed down and limited.

[0077] In this embodiment, when the dual-axis motor 15 is started, the two rotating shafts 16 at its output end rotate, thereby driving the two cutting wheels 17 to rotate at high speed. The cutting wheels 17 accurately cut the copper foil that is aligned with the downward limit, completing the edge trimming operation of the copper foil.

[0078] For details, please refer to Figure 5 , the rotating assembly includes:

[0079] The dual-axis motor 15 is fixedly connected to the upper end of the rotating base 14. The output ends on both sides of the dual-axis motor 15 are fixedly connected to the rotating shaft 16. The two rotating shafts 16 have their ends that are spaced apart from each other and are movable through the two side ends of the rotating base 14. The two rotating shafts 16 have their ends that are spaced apart from each other and are fixedly connected to the cutting wheels 17.

[0080] In this embodiment, when the two rotating shafts 16 are respectively fixed to the output ends of the dual-axis motor 15 on both sides, when the dual-axis motor 15 is started, the two rotating shafts 16 at the output ends thereof rotate, thereby driving the two cutting wheels 17 to rotate at high speed.

[0081] For details, please refer to Figure 3 Two stabilizing seats 22 are fixedly connected to the inner walls on both sides of the protection seat 2, and the inner surfaces of the multiple stabilizing seats 22 and the outer surfaces of the two limiting rods 20 are respectively slidably connected.

[0082] In this embodiment, four stabilizing seats 22 are fixed to the inner walls on both sides of the protection seat 2, which are slidably connected to the outer surfaces of the two limiting rods 20 to ensure the stable operation of the mechanism.

[0086] In this embodiment, the upper end of the support base 1 is fixed by four bolts 28 to facilitate installation and maintenance of the device.

[0087] The working principle and usage process of the present invention are as follows: the copper foil is first placed between the two rotating rollers 5. Through the rotation of the two rotating rollers 5, the copper foil is smoothly introduced and conveyed forward. The design of the two rotating rollers 5 on the fixed seat 4 ensures the stability and directionality of the copper foil during the transmission process. When the copper foil needs to be lifted and adjusted, the servo motor 18 is started, and the two nuts 21 are driven to move toward the middle through the rotation of the screw rod 19. The two nuts 21 drive the four push plates 25 to squeeze, thereby slidingly connecting with the cross block 26 so that the cross block 26 slides upward, and then the copper foil is gently lifted through the lifting plate 6 and the lifting cushion 7. Precise height control is achieved. The combination of the electric slide rail 8 and the sliding seat 9, the electric push rod 10 and the lower pressure plate 11 constitutes a pressing mechanism. By driving the electric push rod 10 to extend downward, the lower pressure plate 11 presses the copper foil to ensure that the copper foil is firmly limited before cutting to avoid slippage or offset during the cutting process. The mounting seat 13 and the rotating seat 14 are driven by the control cylinder 12 to adjust the height. When the dual-axis motor 15 is started, the two rotating shafts 16 at its output end rotate, thereby driving the two cutting wheels 17 to rotate at high speed. The cutting wheel 17 accurately cuts the copper foil with the downward limit, completing the edge trimming operation of the copper foil.
