[0029] Please see Figure 1 and Figure 6 An operating table 3 is fixedly installed on the top of the rotating component 9.

[0032] In this embodiment, the sliding action of the sliding plate 517 on the surface of the slide bar 511 and the elastic cooperation of the first spring 512 can provide buffer space during the winding process in accordance with the thickness of the lithium battery electrode sheet, so as to avoid excessive compression and damage to the surface of the lithium battery electrode sheet. At the same time, with the help of the cleaning felt 57 rotating with the flat roller 56, the dust and impurities adhering to the surface of the electrode sheet can be cleaned.
[0033] Please see Figure 1 and Figure 2 The winding assembly 7 is used to wind up lithium battery electrode sheets.

[0035] Please see Figure 1 and Figure 2A transmission assembly 6 is installed between the leveling assembly 5 and the winding assembly 7. The transmission assembly 6 includes two second transmission wheels 64, which are fixedly connected to the shaft ends of the fourth rotating shaft 516 and the fifth rotating shaft 73, respectively. A second transmission belt 63 is connected to the surface of the two second transmission wheels 64. A second bracket 61 is fixedly connected to the side of the second support plate 58. A second motor 62 is fixedly installed on the second bracket 61. The output shaft of the second motor 62 is fixedly connected to the surface of one of the second transmission wheels 64.
[0036] In this embodiment, the second motor 62 drives the second transmission wheel 64, which in turn drives the fourth rotating shaft 516 and the fifth rotating shaft 73 to rotate under the transmission action of the second transmission belt 63. This drives the flattening roller 56 and the winding roller 72 to rotate, thereby achieving the purpose of winding and flattening the lithium battery electrode sheets.
[0037] Please see Figure 1 and Figure 4 A limiting component 8 is fixedly installed on the top of the operating table 3. The limiting component 8 is located below the winding component 7. The limiting component 8 includes an electric push rod 81, which is fixedly connected to the top of the operating table 3. An adjusting plate 82 is fixedly connected to the top of the electric push rod 81. A sliding rod 83 is slidably connected to the top of the adjusting plate 82. A pressure plate 85 is fixedly connected to the top of the sliding rod 83. An anti-slip pad 86 is fixedly connected to the top of the pressure plate 85. A second spring 84 is slidably connected to the surface of the sliding rod 83. The two ends of the second spring 84 are fixedly connected to the adjusting plate 82 and the pressure plate 85, respectively. The tops of the pressure plate 85 and the anti-slip pad 86 overlap with the bottom surface of the winding roller 72. A mounting stud 2 is threaded through the surface of the base 1.
[0038] In this embodiment, the sliding action of the slide bar 511 within the adjusting plate 82, combined with the elasticity of the second spring 84, ensures that the lithium battery electrode sheet is always in contact with the surface of the winding roller 72 by the pressure plate 85 and the anti-slip pad 86, thereby limiting the winding of the lithium battery electrode sheet and ensuring the winding effect. At the same time, the operation of the electric push rod 81 drives the pressure plate 85 and the anti-slip pad 86 to move up and down, making it suitable for use with winding rollers 72 at different heights. The mounting stud 2 can be used to fix the base 1 on the lithium battery sheet making machine, thus enabling the winding mechanism of this application to be installed in the winding working area of the lithium battery sheet making machine.
[0039] The working principle and usage process of this utility model are as follows: First, the base 1 is fixed on the lithium battery sheet making machine by installing the stud 2. Then, according to the usage requirements, the third motor 92 is controlled to drive the operating table 3 to rotate to the appropriate winding position.
[0040] Next, the take-up roller 72 and the leveling roller 56 can be removed, and one side of the shaft end of the take-up roller 72 and the leveling roller 56 can be respectively engaged into the third rotating shaft 514, the fourth rotating shaft 516, and the fifth rotating shaft 73, and fixed with bolts. Then, by controlling the first motor 42 to work, the first transmission wheel 43 is driven to rotate. With the transmission action of the first transmission belt 44, the first transmission wheel 43 drives the two first rotating shafts 46 to rotate, which in turn causes the first lead screw 48 to rotate. This causes the moving plate 49 to drive the first support plate 51 and the third support plate 71 to move towards the leveling roller 56 and the take-up roller 72, so that the cross positioning block 54 is engaged into the cross positioning groove 59 for limiting, and cooperates with the take-up roller 72 and the leveling roller 56 to rotate stably, completing the installation and fixing of the take-up roller 72 and the leveling roller 56.
[0041] Next, the lithium battery electrode sheet can be pulled through two flattening rollers 56 and one end of it can be attached to the surface of the winding roller 72 for winding. Then, by controlling the electric push rod 81, the adjusting plate 82 is moved, so that the pressure plate 85 and the anti-slip pad 86 are in contact with the surface of the lithium battery electrode sheet, limiting the winding lithium battery electrode sheet. Then, by turning on the second motor 62, the second transmission wheel 64 is driven to rotate. With the transmission action of the second transmission belt 63, the two second transmission wheels 64 drive the fourth rotating shaft 516 and the fifth rotating shaft 73 to rotate, which in turn drives the bottom flattening roller 56 and the winding roller 72 to rotate, winding the lithium battery electrode sheet. At the same time, the two flattening rollers 56 and the surface cleaning felt 57 are used to flatten and clean the lithium battery electrode sheet. During the winding process, the sliding action of the sliding plate 517 on the surface of the sliding rod 511 and the elasticity of the first spring 512 provide buffer space to avoid excessive compression of the lithium battery electrode sheet.
[0042] Finally, when the lithium battery electrode is wound up, the electric push rod 81 can be controlled to work, causing the pressure plate 85 and anti-slip pad 86 to separate from the surface of the lithium battery electrode. Then, by controlling the first motor 42 to rotate in the opposite direction, the first transmission wheel 43 is driven to rotate. With the transmission action of the first transmission belt 44, the first transmission wheel 43 drives the two first rotating shafts 46 to rotate, which in turn causes the first lead screw 48 to rotate. This causes the moving plate 49 to move the first support plate 51 and the third support plate 71 away from the flattening roller 56 and the winding roller 72, so that the cross positioning block 54 separates from the cross positioning groove 59. The bolts can be unscrewed and the winding roller 72 can be removed. The flattening roller 56 and the cleaning felt 57 can also be removed simultaneously for cleaning and maintenance.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
