Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to an electrode slicing mechanism and a sodium-ion battery production device. Background Technology

[0002] Sodium-ion batteries are rechargeable batteries that achieve charging and discharging through the migration of sodium ions between the positive and negative electrodes. Their working principle is similar to that of lithium-ion batteries, but they are less expensive and suitable for applications such as energy storage power stations and two-wheeled vehicles. Sodium-ion batteries are rechargeable batteries that primarily rely on the movement of sodium ions between the positive and negative electrodes to complete the charging and discharging process. Their working principle is similar to that of lithium-ion batteries, employing a "rocking chair" electrochemical mechanism: during charging, sodium ions are released from the positive electrode and inserted into the negative electrode; during discharging, they move in the opposite direction.

[0003] For example, the publication number is CN222971139U, the publication date is June 13, 2025, and the title is "An Electrode Sheet Cutting Device for Ion Battery Production". It includes a housing with a collection mechanism inside for collecting graphite powder generated during electrode sheet cutting. The collection mechanism includes an inlet located at the upper middle of the housing, a collection area inside the housing, a dustproof cloth bag installed inside the collection area, and grooves at the upper and lower ends of the collection area. This utility model discloses an electrode sheet cutting device for ion battery production. Air is drawn in from the outside through the inlet to suck the graphite powder generated during cutting into the collection area. To prevent the graphite powder from being sucked into the air pump and causing damage, a dustproof cloth bag is used to contain the graphite powder inside the collection area, facilitating subsequent centralized collection and reducing frequent manual cleaning. It also prevents graphite powder from floating in the air and causing injury.

[0004] In existing technologies, such as those incorporating the aforementioned patents, electrode sheets develop wrinkles due to stacking and compression during storage and handling. If these wrinkles are not smoothed out before cutting, the cutting results will inevitably be affected. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-7 This utility model provides an electrode slicing mechanism, comprising: a frame 1; and two roller groups 2, which are respectively disposed on the frame 1; wherein each roller group 2 consists of two rollers, both of which are rotatably connected to the frame 1, and the electrode passes through the two rollers, as shown in the schematic diagram. Figure 1 , Figure 2 As shown, this allows the bottom of the electrode to come into contact with the frame 1, so that the smoothing assembly 4 can smooth out the wrinkles on the electrode.

[0029] Multiple cutting blades 3 are fixedly connected to the frame 1; each cutting blade 3 abuts against the electrode to cut the electrode.

[0030] The smoothing assembly 4 includes two smoothing units; each smoothing unit includes a rotating cylinder 41 rotatably connected to the frame 1, and a through groove 411 is provided on the rotating cylinder 41; the through groove 411 is inclined; a column 42 is fixedly connected to the frame 1, and a sliding groove 421 is provided on the column; the sliding groove 421 is U-shaped; a slider 43 is slidably connected in the sliding groove 421, and a crossbar 44 is fixedly connected to the slider 43; the crossbar 44 slides against the through groove 411, and a smoothing plate 45 is fixedly connected to the crossbar 44.

[0031] Specifically, the length of the flat plate 45 is greater than or equal to the width of the electrode sheet.

[0032] Preferably, the slide groove 421 is connected to the limiting groove; specifically, the limiting groove is composed of a first segment 422, a second segment 423, and a third segment 424 connected together; more specifically, the end of the third segment 424 away from the second segment 423 is rounded; through this rounding, the elastic element 47 can be elastically deformed and extended by the abutment between the rounded corner and the limiting rod 46, thereby driving the limiting rod 46 to slide into the slider 43, so that the limiting rod 46 slides out and disengages from the third segment 424; the limiting rod 46 is slidably connected inside the slider 43, the limiting rod 46 slides and abuts against the limiting groove, and an elastic element 47 is provided between the limiting rod 46 and the slider 43; specifically, the elastic element 47 is a tension spring.

[0033] It is understandable that the two rotating cylinders 41 have different rotation angles in the initial state, such as... Figure 1 As shown, when one of the smoothing plates 45 is about to begin the smoothing action, the other smoothing plate 45 has already completed the smoothing action and moved upward, and the smoothing plate 45 that has completed the smoothing action is about to begin moving downward to reset.

[0034] Preferably, it also includes a drive assembly 5; which is used to drive the two smoothing units to move; the drive assembly 5 includes two drive units; each drive unit includes a first pulley 51 fixedly connected to the rotating drum 41, a second pulley 52 rotatably connected to the frame 1, a belt 53 is provided between the first pulley 51 and the second pulley 52, a first gear 54 is fixedly connected to the second pulley 52; a second gear 55 is rotatably connected to the frame 1, the second gear 55 meshes with the two first gears 54 respectively, a turntable 56 is rotatably connected to the frame 1, two first racks 57 and two second racks 58 are fixedly connected to the turntable 56, the two first racks 57 and the two second racks 58 respectively mesh with the second gear 55.

[0035] Specifically, in this embodiment, a drive source (not shown in the figure) for driving the turntable 56 to rotate is also included. The drive source is a motor, and the output end of the motor is fixedly connected to the turntable 56 coaxially. The motor is existing technology and will not be described in detail here.

[0036] A sodium-ion battery production apparatus, comprising an electrode slicing mechanism as described in any of the preceding claims.

[0037] In use, the drive turntable 56 rotates. During its rotation, the first rack 57 and the second rack 58 mesh with the second gear 55, thereby driving the second gear 55 to rotate back and forth. When the second gear 55 rotates in one direction, it drives the two rotating drums 41 to rotate in the same direction through the transmission with the first gear 54, the first pulley 51, the second pulley 52, and the belt 53.

[0038] When one of the rotating drums 41 rotates along the first direction, since the crossbar 44 is located at the bottom of the through groove 411, the rotating drum 41 will drive the crossbar 44 and the smoothing plate 45 to rotate synchronously. During the rotation of the smoothing plate 45, the smoothing action of the electrode sheet can be completed. During the sliding of the crossbar 44, the slider 43 slides in the slide groove 421. As the slider 43 slides, when the limiting rod 46 rotates into the first section 422, the elastic element 47 recovers its elastic deformation and contracts, so that the limiting rod 46 is inserted into the first section 422.

[0039] Subsequently, the rotating drum 41 rotates in the opposite direction (i.e., rotates in the second direction). Through the abutment of the crossbar 44 and the through groove 411, and the insertion of the limiting rod 46 and the first section 422, the slider 43, the crossbar 44, and the flat plate 45 move vertically upward synchronously. Immediately afterwards, the rotating drum 41 continues to rotate in the same direction, which will drive the slider 43, the crossbar 44, and the flat plate 45 to rotate synchronously, so that the limiting rod 46 slides from the first section 422 into the second section 423.

[0040] Subsequently, the rotating drum 41 continues to rotate in the first direction. Under the action of gravity, the slider 43, the crossbar 44, and the flat plate 45 move vertically downward, causing the limiting rod 46 to slide into the third section 424. During the downward movement, since the end of the third section 424 is rounded, the rounded corner of the limiting rod 46 abuts against it, driving the limiting rod 46 to retract into the slider 43. This causes the limiting rod 46 to disengage from the third section 424, allowing the slider 43 to slide directly to the bottom without being limited.

[0041] The above describes the working principle of a single smoothing unit. As mentioned above, in the initial state, the rotation angles of the two rotating cylinders 41 are not consistent, so the two smoothing units can alternately perform the following actions: rotational smoothing, rising, rotational reset, and falling reset. Because the two smoothing units alternately smooth the electrode sheet, there are no dead corners during the smoothing process.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
