[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0017] Referring to Figure 1 A foil winding and pressing device, comprising a base 1, a connecting plate 3 rotatably arranged on one side of the base 1 through a rotating shaft, a supporting rod 4 arranged on one side of the top end of the connecting plate 3, a mounting assembly arranged on one side of the bottom end of the supporting rod 4, and a pressure roller assembly mounted on one side of the supporting rod 4 through the mounting assembly.

[0018] The top of the base 1 and the top of the connecting plate 3 are respectively provided with a connecting assembly for connecting the fixed end and the movable end of the buffer cylinder.

[0019] In use, the device can be installed on one side of the winding assembly, and after the electrode sheet is slitting, it enters the winding device. The winding shaft starts to rotate under the drive of the motor, and the electrode sheet is pressed by the pressure roller 7 assembly to prevent it from loosening during winding. When the diameter of the winding changes, the connecting plate 3 installed on the rotating shaft will rotate upward due to the increase in diameter, so that the pressure roller 7 assembly always adheres to the winding electrode sheet. Compared with the prior art, the device sets the connecting plate 3 and the pressure roller assembly, so that the connecting plate 3 also rotates when the diameter of the winding electrode sheet changes, so that the tension remains stable, and finally realizes the tight and neat winding of the electrode sheet. The problem of poor universality in the prior art cannot be self-adaptively adjusted according to the thickness, material and other characteristics of the electrode sheet.

[0020] Further, the pressure roller assembly comprises a supporting block 5 and a pressure roller 7. One side of the supporting block 5 is rotatably installed on one side of the supporting rod 4, and the pressure roller 7 is rotatably arranged at the bottom end of the supporting block 5. By setting the pressure roller 7, the pressure roller 7 can hold the electrode sheet and apply pressure to the electrode sheet to prevent it from loosening during winding. By rotating the supporting block 5, the pressure roller 7 can be adjusted to swing left and right, so that the surface of the pressure roller 7 completely adheres to the foil and does not have a raised edge, thereby increasing the winding effect.

[0021] Further, the connecting assembly comprises a first mounting seat 11 and a second mounting seat 12. The first mounting seat 11 is arranged at the top end of the base 1, and the second mounting seat 12 is arranged at the top end of the connecting plate 3. In use, it is used with a cylinder. The bottom of the cylinder is rotatably arranged on one side of the first mounting seat 11. The driving end of the cylinder is rotatably connected to one side of the second mounting seat 12, and the cylinder is inclined between the first mounting seat 11 and the second mounting seat 12. In use, the driving end of the cylinder abuts against the second mounting seat 12 to prevent the connecting plate 3 from rotating and make the pressure roller 7 adhere to the electrode sheet. When the diameter of the winding electrode sheet increases, the driving end of the cylinder can be moved to drive the connecting plate 3 to rotate and move the pressure roller 7 to make the pressure roller 7 adhere to the electrode sheet, so that the tension remains stable, and finally realizes the tight and neat winding of the electrode sheet. It should be noted that the device is an auxiliary tool, and the cylinder is not within the protection scope of the device, but the device needs to be used with the cylinder.

[0022] In addition, in actual use, a pressure sensor can be arranged on one side of the electrode sheet, which can monitor the pressure in real time and feed back to the control processor, and the control processor automatically adjusts the cylinder pressure according to the pressure condition to drive the connecting plate 3 to rotate to different positions to drive the pressure roller 7 to better adhere to the electrode sheet, and the tension sensor is arranged to monitor the electrode sheet tension, and the control processor adjusts the driving motor speed to ensure that the winding process proceeds smoothly.

[0023] Further, the mounting assembly comprises a mounting block 8 and two bolts 9, the mounting block 8 is fixedly arranged on one side of the supporting rod 4, the two bolts 9 are screwed with the mounting block 8, the bottom ends of the two bolts 9 are movably abutted with the top end of the supporting block 5, and the other sides of the two bolts 9 are screwed with nuts 10, through the arrangement of the bolts 9, in use, one of the bolts 9 can be screwed to move the bolt 9 downward, so that the supporting block 5 connected with the rotating shaft is turned to one side, and the other bolt 9 can limit the supporting block 5 after the offset is completed, preventing the supporting block 5 from rotating when the pressure roller 7 presses the electrode sheet, affecting the winding effect, and at the same time, the angle of the pressure roller can be adjusted.

[0024] Further, the second mounting seat 12 is L-shaped, and the materials of the first mounting seat 11 and the second mounting seat 12 are stainless steel, by setting the materials of the first mounting seat 11 and the second mounting seat 12 as stainless steel, good corrosion resistance in various environments can be achieved, and the device can be applied to various environments.

[0025] The rotating shaft mentioned in the device can be fixedly connected with the supporting rod 4, and the supporting block 5 can be connected with the ceramic bearing, the friction coefficient of the ceramic bearing is lower than that of steel, so that the ceramic bearing runs more smoothly and has lower energy consumption.
