Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] In order for those skilled in the art to better understand the utility model solutions, the utility model will be further described below with reference to the drawings and specific embodiments.

[0027] The application provides a copper foil winding device, which comprises a first support 1 and a second support 2, a swing frame is rotatably arranged between the first support 1 and the second support 2, an oscillating cylinder 3 is hinged between the swing frame and the second support 2, the oscillating cylinder 3 is used for rotating the swing frame, and the relative position of the end of the swing frame and a copper foil roll is adjusted. Further, the swing frame comprises two parallel swing arms 4, each swing arm 4 is provided with an adjusting block 5 connected thereto, a first hinged plate 6 is rotatably arranged on the adjusting block 5, the rotation axis of the first hinged plate 6 is perpendicular to the side wall of each swing arm 4, an elastic part 7 is connected to one end of each first hinged plate 6 away from the copper foil roll, the elastic part 7 applies a pulling force to the end of the first hinged plate 6, so that the other end of the first hinged plate 6 is lifted away from the adjusting block 5, a flattening roller 63 is clamped between the other ends of each first hinged plate 6, the flattening roller 63 is rotatable between each first hinged plate 6, and the rotation axis of the flattening roller 63 is parallel to the axis of the copper foil roll. During the winding of the copper foil, according to the diameter of the copper foil roll, the oscillating cylinder 3 is used to preliminarily attach the flattening roller 63 at the end of the swing frame to the copper foil roll, the elastic part 7 pulls the end of the first hinged plate 6, so that the flattening roller 63 at the other end of the first hinged plate 6 is in soft contact with the copper foil roll, a pressure is applied to the copper foil, the copper foil roll after winding is more compact, air is avoided to be stored in the copper foil roll, and a bulge is avoided to be generated. In addition, as the winding of the copper foil continues, the diameter of the copper foil roll gradually increases, the copper foil roll applies a pressure to the flattening roller 63, the first end of the first hinged plate 6 provided with the elastic part 7 is lifted, the pressure between the copper foil roll and the flattening roller 63 is relieved, the winding process is more stable, and uneven stress on the copper foil is avoided to cause the copper foil to swing.

[0028] It should be noted that the adjusting block 5 is arranged on the opposite end surface of each swing arm 4, and a pair of clamping plates 51 are arranged on the end surface of the adjusting block 5 along the height direction thereof and close to one side of the copper foil roll. The pair of clamping plates 51 are arranged at intervals, and the interval between the pair of clamping plates 51 is slightly greater than the first hinged plate 6. The first hinged plate 6 is clamped between the pair of clamping plates 51. Each clamping plate 51 is provided with a swing shaft 62 at the end away from the adjusting block 5, so that the hinged plate rotates around the swing shaft 62. Preferably, the swing shaft 62 is arranged at the midpoint of the first hinged plate 6 along the length direction. The elastic member 7 pulls the end of the first hinged plate 6 connected thereto, so that the first hinged plate 6 is close to the adjusting block 5. The elastic member 7 takes the swing shaft 62 as a fulcrum, and the ironing roller 63 at the other end of each first hinged plate 6 is raised away from the adjusting block 5. The side wall of the ironing roller 63 abuts against the side wall of the copper foil roll. In the process of rotating and winding the copper foil, the side wall of the ironing roller 63 pushes against the copper foil, so that the copper foil is closely attached to the side wall of the copper foil roll, thereby preventing air from being trapped during winding and forming a bulge.

[0029] Please refer to the accompanying drawings Figure 4 and the accompanying drawings Figure 5 A sliding rod 61 is slidably arranged on the adjusting block 5 and extends along the height direction of the adjusting block 5. The length of the sliding rod 61 is greater than the height of the adjusting block 5, that is, after the sliding rod 61 is arranged on the adjusting block 5, the two ends of the sliding rod 61 extend out of the end surface of the adjusting block 5 perpendicular to the height direction. A baffle 64 is arranged at the end of the sliding rod 61 away from the clamping plate 51. The elastic member 7 is clamped between the baffle 64 and the end surface of the adjusting block 5, and the elastic member 7 is sleeved on the sliding rod 61. The end of the sliding rod 61 away from the elastic member 7 is hinged to the end of the first hinged plate 6 away from the ironing roller 63. In an embodiment of the present application, during the initial stage of winding the copper foil roll, the elastic member 7 is compressed, the baffle 64 is held by the elastic member 7, the distance between the baffle 64 and the adjusting block 5 increases, that is, the sliding rod 61 slides towards the end close to the elastic member 7. The sliding rod 61 pulls the end of the first hinged plate 6 connected thereto, so that the end of the first hinged plate 6 connected to the ironing roller 63 moves away from the end of the elastic member 7. The ironing roller 63 exerts pressure on the copper foil roll through the elastic member 7. The ironing roller 63 abuts against the copper foil, so that the copper foil is closely attached to the side wall of the copper foil roll, thereby ensuring that the air between the copper foil and the copper foil roll is completely discharged. After a certain amount of copper foil is wound, the diameter of the copper foil roll gradually increases, and the pressure exerted by the copper foil roll on the ironing roller 63 increases, so that the ironing roller 63 swings away from the axis of the copper foil roll, so that the pressure exerted by the ironing roller 63 on the side wall of the copper foil roll is within an appropriate range. This avoids the position of the ironing roller 63 being locked with the copper foil roll. If the pressure between the copper foil roll with increased thickness and the ironing roller 63 is too large, the copper foil is clamped and locked between the ironing roller 63 and the copper foil roll, and the operation of the copper foil winding device is stopped.

[0032] Preferably, a swing rod 41 is arranged at the end of each swing arm 4 away from the smoothing roller 63, the swing rod 41 is arranged perpendicularly to each swing arm 4 and extends out of the side wall of each swing arm 4, a fixing sleeve is clamped between each swing arm 4 and the swing rod 41, so that the swing arm 4 is fixedly connected with the swing rod 41 and can rotate with the swing rod 41, the two ends of the swing rod 41 are connected with the first support 1 and the second support 2 respectively, the swing rod 41 is fixedly connected with one end of the second hinge plate 11, the other end of the second hinge plate 11 is hingedly connected with the swing oil cylinder 3, the end of the swing oil cylinder 3 away from the second hinge plate 11 is hingedly connected with the second support 2, the swing oil cylinder 3 pushes against the end of the second hinge plate 11, so that the end of the second hinge plate 11 connected with the swing rod 41 rotates, and the swing arm 4 connected with the swing rod 41 rotates accordingly, in addition, the end of the swing rod 41 away from the second hinge plate 11 is connected with the first support 1 through the rotating seat 12, and a rolling bearing is clamped between the swing rod 41 and the rotating seat 12, so that the rotation of the swing rod 41 is smoother. When the winding amount of the copper foil roll is large, and the swing of the first hinge plate 6 cannot relieve the pressure between the smoothing roller 63 and the copper foil roll, the swing oil cylinder 3 swings the swing arm 4 away from the axis of the copper foil roll, so that the smoothing roller 63 abutting against the copper foil roll returns to the original state, and the first hinge plate 6 has swing space again, so that the copper foil can continue to be wound.
