Description

Technical Field

[0001] This invention relates to the field of lithium battery winding manufacturing, specifically to a dual-drive active feeding device and method for digital battery electrode sheets. Background Technology

[0002] Lithium-ion batteries are formed by winding electrodes and separators. In the production of batteries, existing digital battery winding machines have only one drive roller in their electrode feeding device, which is a single-drive method. Because there is dust on the surface coating of the electrode, after clamping, the drive roller rotates to feed the electrode downward. The drive roller accelerates too fast, and the electrode dust is very fine, which often causes slippage. Summary of the Invention

[0003] To address the aforementioned deficiencies in existing technologies, this invention provides a dual-drive active feeding device and method for digital battery electrode sheets, the specific technical solution of which is as follows:

[0004] A dual-drive active feeding device for digital battery electrodes includes a fixed frame, a fixed base, a main drive roller, a drive motor, a movable base, a driven roller, and a synchronous transmission mechanism. The fixed base is fixedly installed on one side inside the fixed frame, and the main drive roller is rotatably installed inside the fixed base. The movable base is slidably installed inside the fixed frame, and the driven roller is rotatably installed inside the movable base. The drive motor drives the movable base to move left and right through the synchronous transmission mechanism. The synchronous transmission mechanism simultaneously drives the main drive roller and the driven roller to rotate synchronously. The main drive roller and the driven roller cooperate to feed the electrodes.

[0005] As a preferred embodiment of the present invention, the synchronous transmission mechanism includes a driving wheel, a driven wheel set, and a transmission belt. The output shaft of the drive motor is connected to the driving wheel, the driving wheel is installed at one end of the main drive roller, the driven wheel set has multiple driven wheels, the transmission belt winds around the driving wheel and the driven wheel set, and when the transmission belt rotates, it drives the moving seat to move left and right, and the driven wheel set drives the driven roller to rotate.

[0006] As a preferred embodiment of the present invention, the driven wheel assembly includes a first driven wheel, a second driven wheel, a third driven wheel, a fourth driven wheel, and a fifth driven wheel, and the transmission belt is wound around the driving wheel, the first driven wheel, the second driven wheel, the third driven wheel, the fourth driven wheel, and the fifth driven wheel in sequence.

[0009] As a preferred embodiment of the present invention, a rotating shaft is connected to the rear of the third driven wheel, and the rotating shaft drives the driven roller to rotate through a pair of gears.

[0010] As a preferred embodiment of the present invention, the movable seat is slidably installed inside the fixed frame by means of the cooperation of the slider and the slide rail on the front and rear sides.

[0011] A dual-drive active feeding method for digital battery electrodes is provided, which uses the aforementioned dual-drive active feeding device to feed the electrodes.

[0012] Beneficial effects: When the dual-drive active feeding device for digital battery electrodes of the present invention is working, the drive motor drives the moving seat to move left and right through the synchronous transmission mechanism, so that the electrode is clamped by the main drive roller and the driven roller. At the same time, the synchronous transmission mechanism drives the main drive roller and the driven roller to rotate synchronously. The main drive roller and the driven roller cooperate to feed the electrode. Through the above structure, the power of the main drive roller is transmitted to the driven roller in a 1:1 ratio, forming a dual-drive effect, eliminating slippage and ensuring accurate feeding.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0020] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] like Figures 1-6 As shown, a dual-drive active feeding device for digital battery electrodes includes a fixed frame 1, a fixed base 2, a main drive roller 3, a drive motor 4, a movable base 5, a driven roller 6, and a synchronous transmission mechanism. The fixed base 2 is fixedly installed on one side inside the fixed frame 1. The main drive roller 3 is rotatably installed inside the fixed base 2. The movable base 5 is slidably installed inside the fixed frame 1. The driven roller 6 is rotatably installed inside the movable base 5. The drive motor 4 drives the movable base 5 to move left and right through the synchronous transmission mechanism. The synchronous transmission mechanism simultaneously drives the main drive roller 3 and the driven roller 6 to rotate synchronously. The main drive roller 3 and the driven roller 6 cooperate to feed the electrode 7.

[0023] Specifically, the synchronous transmission mechanism includes a driving wheel 8, a driven wheel set, and a transmission belt 9. The output shaft of the drive motor 4 is connected to the driving wheel 8. The driving wheel 8 is installed at one end of the main drive roller 3. The driven wheel set has multiple driven wheels. The transmission belt 9 winds around the driving wheel 8 and the driven wheel set. When the transmission belt 9 rotates, it drives the moving seat 5 to move left and right. The driven wheel set drives the driven roller 6 to rotate.

[0024] Specifically, the driven pulley assembly includes a first driven pulley 10, a second driven pulley 11, a third driven pulley 12, a fourth driven pulley 13, and a fifth driven pulley 14. The transmission belt 9 sequentially winds around the driving pulley 8, the first driven pulley 10, the second driven pulley 11, the third driven pulley 12, the fourth driven pulley 13, and the fifth driven pulley 14, with the side facing the fixed base 2 as the left and the side away from the fixed base 2 as the right. The first driven pulley 10 is located above the driving pulley 8 and is mounted in front of the fixed base 2. The second driven pulley 11 is mounted on a fixed frame 15, which is located on the opposite side of the fixed base 2. The fixed frame 15 is on the right side, and the movable seat 5 is located between the fixed seat 2 and the fixed frame 15. The third driven wheel 12 and the fourth driven wheel 13 are installed on the movable seat 5, and the fifth driven wheel 14 is installed on the fixed seat 2. The third driven wheel 12 is lower than the fourth driven wheel 13 and is further to the left than the fourth driven wheel 13. The fifth driven wheel 14 is higher than the driving wheel 8 and lower than the first driven wheel 10. Since the positions of the driving wheel 8, the first driven wheel 10, the second driven wheel 11, and the fifth driven wheel 14 remain unchanged, the third driven wheel 12 and the fourth driven wheel 13 can drive the movable seat 5 to move when the transmission belt 9 rotates.

[0025] Specifically, the third driven wheel 12 is connected to the rotating shaft 16 at the rear. The rotating shaft 16 drives the driven roller 6 to rotate through a pair of gears 17, so as to make the driven roller 6 rotate in the opposite direction. In addition, the movable seat 5 is slidably installed inside the fixed frame 1 through the cooperation of the slider and the slide rail 18.

[0026] A dual-drive active feeding method for digital battery electrodes is provided, which uses the aforementioned dual-drive active feeding device to feed the electrodes.

[0027] Working principle of the dual-drive active feeding device: When feeding is required, the drive motor 4 drives the drive wheel 8 to rotate clockwise, and each driven wheel rotates as follows: Figure 5 As shown in the diagram, the transmission belt 9 rotates clockwise, causing the movable seat 5 to move closer to the fixed seat 2. The movable seat 5, along with the driven roller 6, moves, causing the electrode sheets to be clamped and fed by the main drive roller 3 and the driven drive roller 6. When the machine stops and feeding occurs, the drive motor 4 drives the drive wheel 8 to rotate counterclockwise, and each driven wheel moves as shown in the diagram. Figure 6 As shown, the transmission belt 9 rotates counterclockwise, and the moving seat 5 moves away from the fixed seat 2.

[0028] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the protection scope of the present invention.
