[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," etc., are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In particular, the understanding of the term "upper" following a noun in the claims should be understood as meaning that the entire inner and outer surfaces of the structure referred to by the noun conform to the definition of "upper."

[0028] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structures, features, and effects provided in this application.

[0029] like Figure 1 and Figure 2 As shown, an electrode chamfering die includes a first chamfering upper mounting plate 1, a first chamfering pressure plate 2, a first chamfering punch 3, a first chamfering die 4, and a first chamfering lower mounting plate 5. The first chamfering pressure plate 2 and the first chamfering punch 3 are both mounted on the first chamfering upper mounting plate 1, and the first chamfering die 4 is mounted on the first chamfering lower mounting plate 5. The first chamfering upper mounting plate 1 is mounted on the first chamfering lower mounting plate 5 through a guide post assembly 6.

[0030] like Figure 3 As shown, in one embodiment, the bottom surface of the first chamfering punch 3 is provided with a first inclined relief groove 31, and the first inclined surface of the first inclined relief groove 31 is provided with a first air blowing hole 32. The first inclined relief groove 31 on the bottom surface of the first chamfering punch 3 and the first air blowing hole 32 on its first inclined surface can guide the edge of the electrode sheet smoothly into the chamfering area. At the same time, the blown air can promptly discharge the debris generated during the chamfering process, preventing debris accumulation or jamming, reducing the adhesion and jamming risk between the electrode sheet and the die, thereby improving the chamfering accuracy and quality, extending the die life, ensuring the smooth progress of subsequent processing, and improving the overall performance and production efficiency of the battery electrode sheet.

[0031] like Figure 4 and Figure 5As shown, in one embodiment, the first chamfering die 4 is provided with a first blanking groove 41, and a first clearance groove 42 is formed on the side of the first blanking groove 41 along the electrode discharge direction. The first blanking groove 41 on the first chamfering die 4, and the first clearance groove 42 formed on the side of the first clearance groove 42 along the electrode discharge direction, facilitate the quick and smooth removal of the chamfered electrode from the die, avoid the electrode being obstructed in the discharge direction, reduce the risk of electrode deformation or damage, and improve production efficiency.

[0032] like Figure 4 As shown, in one embodiment, the inner wall of the first material discharge trough 41 is provided with a second air blowing hole 411. The second air blowing hole 411 can blow out gas in time, effectively cleaning the residual debris or dust on the inner wall of the first material discharge trough 41, preventing these impurities from affecting the output quality of the electrode sheet and the accuracy of subsequent processing.

[0033] like Figure 6 As shown, in one embodiment, the second air hole 411 is inclined downward. The downward inclination can more effectively blow out debris or dust in the first discharge trough 41 along the discharge direction, preventing impurities from accumulating in the discharge trough, thereby further improving the smoothness of electrode discharge and the cleanliness of the processing environment, while reducing the impact of impurities on subsequent electrode chamfering processing, ensuring processing accuracy and mold durability.

[0034] like Figure 7 As shown, in one embodiment, the first chamfering pressure plate 2 is mounted on the first chamfering mounting plate 1 via the first guide post 21 and the first reset spring 22.

[0035] The principle of this application is as follows:

[0036] When rounding the corners of the battery electrode, the electrode is first placed on the first chamfering die 4. The first chamfering pressure plate 2 is mounted on the first chamfering mounting plate 1 via the first guide post 21 and the first return spring 22, and can float to a certain extent in the vertical direction. When the first chamfering mounting plate 1 moves downward, the first chamfering pressure plate 2 first contacts the electrode and presses it firmly onto the first chamfering die 4 to prevent the electrode from shifting or deforming during the chamfering process.

[0037] Next, the first chamfering punch 3 continues to move downward under the drive of the first chamfering mounting plate 1, cooperating with the first chamfering die 4 to round the side of the electrode sheet. The bottom surface of the first chamfering punch 3 is provided with a first inclined relief groove 31. The first inclined surface of the groove guides the edge of the electrode sheet into the chamfering area. At the same time, the first air blowing hole 32 can blow out gas, which helps to remove the debris generated during the processing and prevents the debris from affecting the processing accuracy or getting stuck in the mold.

[0038] After the chamfering is completed, the mounting plate 1 on the first chamfer returns to its original position, and the first return spring 22 drives the first chamfering pressure plate 2 to move upward together, releasing the electrode sheet. At this time, the first discharge groove 41 facilitates the smooth discharge of the electrode sheet, while the first clearance groove 42 avoids interference of the electrode sheet in the discharge direction. At the same time, the second air blowing hole 411 on the inner wall of the first discharge groove 41 blows gas downward at an angle, further assisting the discharge of the electrode sheet, preventing the electrode sheet from adhering to the mold, and ensuring the continuity and efficiency of the processing.

[0039] The embodiments described above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
