Abstract

This utility model relates to a safety electrode double-cutting waste collection mechanism, including an upper cutting blade seat, an upper cutting blade, a lower cutting blade seat, a lower left cutting blade, a lower right cutting blade, a lower support, a vacuum chamber adsorption plate, and an extension cylinder. The upper cutting blade is installed in the upper cutting blade seat, and the lower left and lower right cutting blades are installed in the lower cutting blade seat. The lower left and lower right cutting blades are separated to form a cutting zone. The upper cutting blade is located above the cutting zone. The lower cutting blade seat is mounted on the lower support, and an extension cylinder is installed in front of the lower support. The lower cutting blade seat has an adsorption plate receiving groove, which is located directly below the cutting zone. The vacuum chamber adsorption plate is located in the adsorption plate receiving groove. The extension cylinder drives the vacuum chamber adsorption plate to extend into the cutting zone and approach the electrode. The adsorption micropores attract the waste, ensuring that no waste is drawn in during the winding process, thus not affecting the feeding efficiency. This effectively collects the waste generated during double-cutting, improving product safety and equipment winding efficiency.

Description

Technical Field

[0001] This utility model relates to the field of sheet winding machines, specifically to a safety electrode double-cut waste collection mechanism. Background Technology

[0002] Currently, in lithium-ion battery manufacturing, the feeding mechanism of the electrode winding machine is equipped with a double-cutting mechanism at its end. After the electrode and separator are fed to the specified length, the double-cutting mechanism performs a clean, neat, and synchronous transverse cut to form an independent, precisely sized cell prototype, preparing it for subsequent winding. The advantages of the double-cutting mechanism compared to the single-cutting mechanism are: the upper and lower blades cut in opposite directions, effectively avoiding metal burrs; the shearing force is uniform, resulting in smooth electrode edges without indentations, warping, or twisting, ensuring flat electrode feeding. However, this double-cutting method generates excess electrode waste. If not removed promptly, it will affect subsequent winding processes and the next cut. Therefore, it is necessary to improve the structure of the existing double-cutting mechanism. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a safe electrode double-cutting waste collection mechanism to solve the problem of effectively collecting waste materials during double-cutting. The specific technical solution is as follows: A safety electrode double-cutting waste collection mechanism includes an upper cutting blade holder, an upper cutting blade, a lower cutting blade holder, a lower left cutting blade, a lower right cutting blade, a lower support, a vacuum chamber adsorption plate, and an extension cylinder. The upper cutting blade is installed in the upper cutting blade holder, and the lower left and lower right cutting blades are installed in the lower cutting blade holder. The lower left and lower right cutting blades are separated to form a cutting zone. The upper cutting blade is located above the cutting zone. The lower cutting blade holder is mounted on the lower support. An extension cylinder is installed in front of the lower support. The lower cutting blade holder has an adsorption plate receiving groove located directly below the cutting zone. The vacuum chamber adsorption plate is located in the adsorption plate receiving groove. The extension cylinder drives the vacuum chamber adsorption plate to extend into the cutting zone and approach the electrode. The surface of the vacuum chamber adsorption plate has multiple adsorption micropores, and the inside of the vacuum chamber adsorption plate has a vacuum chamber.

[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings: In the description of this utility model, 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 utility model 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 limitations on this utility model.

[0012] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model according to the specific circumstances.

[0013] like Figures 1-4As shown, a safety electrode double-cutting waste collection mechanism includes an upper cutter holder 1, an upper cutter 2, a lower cutter holder 3, a lower left cutter 4, a lower right cutter 5, a lower support 6, a vacuum chamber adsorption plate 7, and an extension cylinder 8. The upper cutter 2 is installed in the upper cutter holder 1, and the lower left cutter 4 and lower right cutter 5 are installed in the lower cutter holder 3. The lower left cutter 4 and lower right cutter 5 are separated to form a cutting zone 9. The upper cutter 2 is located above the cutting zone 9, and the lower cutter holder 3 is mounted on the lower support 6. An extension cylinder 8 is installed at the front, and an adsorption plate receiving groove 10 is provided in the lower cutter holder 3. The adsorption plate receiving groove 10 is located directly below the cutting zone 9. The vacuum chamber adsorption plate 7 is located in the adsorption plate receiving groove 10. The extension cylinder 8 drives the vacuum chamber adsorption plate 7 to extend into the cutting zone 9 and approach the electrode. The surface of the vacuum chamber adsorption plate 7 is provided with multiple adsorption micropores 71. The vacuum chamber adsorption plate 7 is provided with a vacuum chamber 72 inside. The adsorption micropores 71 are connected to the vacuum chamber 72, and the adsorption micropores 71 adsorb waste material.

[0014] Specifically, the piston rod of the extended cylinder 8 is connected to the connecting plate 11, and a vacuum pipe connector 12 is installed on the side of the connecting plate 11. The connecting plate 11 is connected to the vacuum chamber adsorption plate 13. The connecting plate is provided with a channel for the vacuum pipe connector to connect to the vacuum chamber. One end of the vacuum pipe connector 12 is connected to an external vacuum device, and the other end is connected to the vacuum chamber 72 through the channel. When the vacuum chamber 72 forms a vacuum state, the adsorption micropores adsorb the waste material. The pore size of the adsorption micropores is less than 2mm to prevent the waste material from directly entering the adsorption micropores.

[0015] Specifically, a waste suction pipe 14 is installed on the side of the lower support 6, and a transverse slide rail 14 and a transverse cylinder 15 are installed below the lower support 6. The transverse slide rail 14 extends laterally, and an extension cylinder 8 is slidably installed on the transverse slide rail 14. The transverse cylinder 15 is a rodless cylinder. The transverse cylinder 15 drives the extension cylinder 8 to move, thereby driving the vacuum chamber adsorption plate 13 to move laterally into the waste suction pipe 14. This facilitates the external dust collection device to suck up the waste adhering to the adsorption micropores. The cross-section of the adsorption plate receiving groove 10 is a trapezoidal groove with a smaller top and a larger bottom, which is conducive to the collection of waste.
