Meanwhile, the flattening assembly 3 can fold the flattened copper foil upward, thereby not affecting the movement of the cut copper foil into the collecting inclined frame 14.

[0036] The flattening mode of the flattening assembly 3 is as follows: when the copper foil is cut and falls into the collecting inclined frame 14, the sliding rod 35 is located at the upper end of the guide block 34 and away from the side of the guide plate 341, with the rotation of the sliding rod 35, the sliding rod 35 moves downward from the right angle of the right-angled trapezoidal structure of the guide groove formed between the guide frame 33 and the guide block 34, drives the pressing rod 36 hinged to the left end of the sliding rod 35 to move downward, and makes the flattening plate 361 tightly abut against the copper foil under the action of the tension spring 362, then the sliding rod 35 moves to the front and rear sides of the copper foil along the guide groove formed between the guide frame 33 and the guide block 34, and drives the flattening plate 361 to smooth the surface of the copper foil, when the sliding rod 35 moves to the guide plate 341, the guide plate 341 is lifted by the sliding rod 35 to continue to move horizontally, drives the flattening plate 361 to completely flatten the copper foil, and makes the flattening plate 361 move along the protrusion of the edge of the collecting inclined frame 14, when the sliding rod 35 moves to the other side of the guide plate 341, the guide plate 341 falls back under the action of the torsion spring.

[0037] The upward retracting mode of the flattening assembly 3 is as follows: when the copper foil is transmitted to the right side by the driving roller 12, the two sliding rods 35 start to move towards each other, the sliding rods 35 move upwards under the guidance of the guide plates 341 and the guide blocks 34, so that the flattening plates 361 move above the copper foil, and then the sliding rods 35 continue to move along the straight trapezoidal structure of the guide groove formed between the guide frame 33 and the guide block 34, until the next cut copper foil falls into the collecting inclined frame 14.

[0038] Referring to Figure 1 、 Figure 5 The upper side of the mounting frame 32 is provided with an arc-shaped sliding rail 321, the arc-shaped sliding rail 321 is provided with a sliding block 322 in a sliding fit mode, a through hole is pre-provided in the middle of the sliding block 322, a linkage rod 323 penetrates through the through hole of the sliding block 322 and is fixedly connected to the upper side of the sliding rod 35, a return spring 324 is sleeved to the outer side of the upper end of the linkage rod 323, the return spring 324 is installed between the upper end of the linkage rod 323 and the upper side of the sliding block 322, the right side of the sliding block 322 is connected with a rotating rod 37, the lower end of the rotating rod 37 is rotatably connected to the flattening support 31 through a bearing, the rotating rods 37 above the two mounting frames 32 are synchronously rotated by driving elements, the upper end of the rotating rod 37 is provided with a gear, the driving element comprises an electric push rod 38 provided between the two mounting frames 32, the telescopic end of the electric push rod 38 is connected with a connecting rod 39, the two ends of the connecting rod 39 are symmetrically provided with racks, the racks on the connecting rod 39 are engaged with the gears provided at the upper end of the rotating rod 37, and the above structure can drive the sliding rod 35 to periodically slide back and forth in the guide groove formed between the guide frame 33 and the guide block 34, so that the flattening plate 361 flattens the copper foil falling into the collecting inclined frame 14 to both sides, specifically, when the telescopic end of the electric push rod 38 is elongated, the telescopic end of the electric push rod 38 drives the racks at the two ends of the connecting rod 39 to move rightwards, so that the two rotating rods 37 rotate towards each other, and the rotating rod 37 can synchronously rotate the sliding rod 35 through the sliding block 322 and the linkage rod 323.

[0039] In addition, the application also provides an automatic cutting process for copper foil production, and the specific steps are as follows: S1, manually placing a copper foil roll: placing the copper foil roll on the unwinding driving roller 22, and manually pulling one end of the copper foil out and through the conveying roller 11, the wrinkle removing plate 17, the driving roller 12, the cutter 13 and the flattening roller 154.

[0040] S2, flattening before cutting: starting the automatic cutting equipment for copper foil production, the unwinding driving roller 22 and the driving roller 12 synchronously rotate to drive the copper foil to move forward, and the wrinkle removing plate 17 flattens the copper foil.

[0041] S3, tension cutting: because the clamping force of the flattening roller 154 and the driven roller 155 on the copper foil is smaller than the driving force of the driving roller 12 on the copper foil and the speed is fast, the cooperation of the clamping of the flattening roller 154 and the driven roller 155 on the copper foil and the driving of the driving roller 12 on the copper foil can tension and flatten the copper foil during slitting.

[0042] S4, flattening and collecting: the slitted copper foil slides into the collecting inclined frame 14 and is flattened under the action of the flattening assembly 3.

[0043] When the copper foil cutting is completed and slides into the collecting inclined frame 14, the extension and retraction movement of the electric push rod 38 drives the movement of the rack at both ends of the connecting rod 39, so that the two rotating rods 37 rotate outward synchronously. At this time, the lower pressing rod 36 at the left end of the sliding rod 35 makes the flattening plate 361 tightly adhere to the copper foil under the action of the tension spring 362, and then the sliding rod 35 moves along the guide groove formed between the guide frame 33 and the guide block 34 to the front and rear sides of the copper foil respectively, and drives the flattening plate 361 to smooth the surface of the copper foil. When the sliding rod 35 moves to the guide plate 341, the sliding rod 35 lifts the guide plate 341 to continue horizontal movement, drives the flattening plate 361 to completely flatten the copper foil, and makes the flattening plate 361 move along the protrusions of the edge of the collecting inclined frame 14. When the sliding rod 35 moves to the other side of the guide plate 341, the guide plate 341 falls back under the action of the torsion spring. When the copper foil is transmitted to the right side by the driving roller 12, the two sliding rods 35 begin to move inward synchronously. The sliding rod 35 moves upward under the guidance of the guide plate 341 and the guide block 34, so that the flattening plate 361 moves above the copper foil, thereby not affecting the transmission of the copper foil. Then the sliding rod 35 continues to move along the right angle trapezoidal structure of the guide groove formed between the guide frame 33 and the guide block 34 until the next slitted copper foil slides into the collecting inclined frame 14.
