Description

Technical Field

[0001] This application relates to the field of electrode production technology, and in particular to a co-track cutting device and an electrode production line. Background Technology

[0002] The electrode production process involves coating, rolling, and slitting. Coating involves evenly spreading the active material slurry onto the substrate surface, leaving parallel blank areas; these blank areas are reserved for the subsequent fabrication of electrode tabs. Rolling involves compacting the coated and dried material using rollers to increase its energy density. Slitting involves cutting the compacted material into narrow strips.

[0003] In actual production, the low surface flatness of the material before slitting leads to a high risk of quality problems such as edge curling after slitting, which affects the yield and quality of subsequent production. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a same-track pressing and cutting device and an electrode production line to solve the problem of low cutting quality of existing slitting devices.

[0047] 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, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0048] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "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 the embodiments of this application and 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. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of the embodiments of this application, 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 replaceable 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 the embodiments of this application according to the specific circumstances.

[0050] Please see Figures 1 to 5 In this application, a first aspect provides a co-track cutting device, including: a slitting mechanism 100 and a rolling mechanism 200; the slitting mechanism 100 is used to slit the material; the rolling mechanism 200 is used to roll the blank areas of the material; the rolling mechanism 200 and the slitting mechanism 100 are arranged adjacent to each other, and the rolling mechanism 200 and the slitting mechanism 100 are arranged on the same track along the material's conveying direction. In this embodiment, the material can refer to a strip of material with blank areas after coating. The slitting position of the slitting mechanism 100 is aligned with the blank areas.

[0051] In this scheme, the roller pressing mechanism 200 and the slitting mechanism 100 are set on the same trajectory, which means that the same point on the material can pass through the two of them in sequence along the conveying direction.

[0052] In one implementation, the slitting mechanism 100 is located upstream of the roller pressing mechanism 200. The material slited by the slitting mechanism 100 enters the roller pressing mechanism 200, so that the slitting position can be roller pressed, avoiding quality problems such as edge curling of the material after slitting.

[0053] In one implementation, the slitting mechanism 100 is located downstream of the rolling mechanism 200. The material to be slitting is first rolled by the rolling mechanism 200 and then fed into the slitting mechanism 100 along the same track, ensuring that the cutting position of the slitting mechanism 100 is compacted. In practical applications, the inventors have found that materials that have not been rolled or have long rolling intervals have low surface flatness. Therefore, in this embodiment, feeding the rolled material into the slitting mechanism 100 along the same track reduces the risk of cutting quality problems due to low surface flatness, thereby reducing issues such as warping.

[0054] In other embodiments, multiple roller pressing mechanisms 200 may be provided, and they may be respectively provided upstream and downstream of the slitting mechanism 100, so as to perform roller pressing on both the materials before and after slitting, thereby further improving the slitting quality.

[0055] In a more specific embodiment, the slitting mechanism 100 includes a first support roller 110 and a slitting element 120; the rolling mechanism 200 includes a second support roller 210 and a rolling element 220; the first support roller 110 and the second support roller 210 are arranged adjacent to each other along the material's conveying direction; the slitting element 120 is used to slit the material on the first support roller 110; the rolling element 220 is used to roll the material on the second support roller 210; the rolling element 220 and the slitting element 120 are arranged on the same trajectory along the material's conveying direction.

[0056] like Figure 1 As shown, the first support roller 110 and the second support roller 210 can both be mounted on the support frame and are arranged in parallel. The roller pressing component 220 and the slitting component 120 are arranged on the same trajectory, which can ensure that the area to be slit before slitting or the edge of the material after slitting passes through the roller pressing component 220.

[0057] In practical applications, there can be multiple slitting parts 120 and roll forming parts 220, which correspond one-to-one along the conveyor belt track.

[0058] It should be noted that the area slitting by the slitting component 120 is the blank area on the material. Correspondingly, the rolling area of ​​the roller pressing component 220 is the blank area. The roller pressing component 220 can flatten the blank area before and after slitting, reducing problems such as folding, curling, or wrinkling in the blank area.

[0059] In one embodiment, the slitting element 120 can be a rotatable blade. The pressing element 220 can be a cylindrical pressing roller structure.

[0060] In this embodiment, the slitting mechanism 100 is equipped with a second driving member 150, which drives the first support roller 110 to rotate, thereby conveying the material. In practical applications, the second driving member 150 can be a motor or the like.

[0061] In this embodiment, the roller pressing mechanism 200 is equipped with a third driving member 250, which drives the second support roller 210 to rotate, thereby conveying the material. In practical applications, the third driving member 250 can be a motor or the like.

[0062] In this embodiment, the material passes between the slitting member 120 and the first support roller 110, and between the rolling member 220 and the second support roller 210.

[0063] In this embodiment, a fourth driving member 140 is provided on the slitting mechanism 100, and the fourth driving member 140 is connected to the slitting member 120 to drive the slitting member 120 to rotate. In application, the fourth driving member 140 can be provided on the first slide rail 130 described below.

[0064] In this embodiment, a fifth driving member 260 is provided on the roller pressing mechanism 200. The fifth driving member 260 is connected to the roller pressing member 220 to drive the roller pressing member 220 to rotate, thereby adapting to the material conveying process and working together with the second support roller 210 to convey the material.

[0065] In this embodiment, double-sided rolling of the material can be achieved through the roller pressing component 220 and the second support roller 210.

[0066] In one embodiment, see Figure 2 The slitting mechanism 100 further includes: a first slide rail 130; the first slide rail 130 is arranged parallel to the first support roller 110, that is, the length direction of the first slide rail 130 is the axial direction of the first support roller 110; the slitting member 120 is slidably arranged on the first slide rail 130.

[0067] In practical applications, the first slide rail 130 can be equipped with linear drive components such as cylinders to drive the slitting piece 120 to move along the length of the first slide rail 130, thereby adjusting the position of the slitting piece 120 to accommodate materials of different sizes.

[0068] Furthermore, a positioning element 121 is provided on the slitting piece 120 so that the control mechanism of the same trajectory pressing and cutting device can determine the position of the slitting piece 120.

[0069] In one embodiment, a plurality of lower cutting shafts 111 are provided on the first support roller 110; the lower cutting shafts 111 are slidable along the axial direction of the first support roller 110.

[0070] The lower cutter shaft 111 provides support when the slitting piece 120 cuts the material. In this embodiment, the number of lower cutter shafts 111 corresponds to the number of slitting pieces 120, and the lower cutter shafts 111 can be adjusted according to the position of the slitting pieces 120. In practical applications, the position of the lower cutter shaft 111 can be adjusted manually by the operator before production.

[0071] In one embodiment, the rolling mechanism 200 further includes: a second slide rail 230; the second slide rail 230 is arranged parallel to the second support roller 210, that is, the length direction of the second slide rail 230 is the axial direction of the second support roller 210; the rolling member 220 is slidably arranged on the second slide rail 230.

[0072] The second slide rail 230 allows the roller press 220 to be adjusted to match the position of the slitting piece 120.

[0073] In application, the position of the roller 220 can be adjusted manually by the operator or by setting a linear drive connected to the roller 220 to achieve electronic control adjustment.

[0074] In one embodiment, the rolling mechanism 200 further includes: a first driving member 240; the output end of the first driving member 240 is connected to the rolling member 220, and is used to drive the rolling member 220 to move radially along the second support roller 210 to approach or move away from the second support roller 210.

[0075] The distance between the first driving member 240 and the second support roller 210 can be adjusted by adjusting the pressure of the roller pressing mechanism 200 on the material.

[0076] In one embodiment, see Figures 1 to 6 The same trajectory pressing and cutting device provided in this embodiment also includes a dust removal component 400; the dust removal component 400 is disposed on the side of the first support roller 110 facing away from the cutting piece 120, and the dust removal component 400 covers the side of the first support roller 110.

[0077] In this embodiment, the slitting component 120 is disposed on the top of the first support roller 110, and correspondingly, the dust removal component 400 is disposed on the bottom surface of the first support roller 110. Furthermore, the dust removal component 400 covers the bottom surface of the first support roller 110.

[0078] In one implementation, the top surface of the dust removal component 400 can be adapted to the arc-shaped surface of the first support roller 110, and a dust suction port is provided at the bottom of the arc-shaped surface to suck away the dust generated during cutting.

[0079] In one embodiment, see Figure 1 It also includes a take-up and unwind assembly 300; the take-up and unwind assembly 300 includes: a third slide rail 310 and a plurality of take-up and unwind rollers 320; the take-up and unwind rollers 320 are slidably disposed on the third slide rail 310 for taking up and unwinding materials; the length direction of the third slide rail 310 is parallel to both the first support roller 110 and the second support roller 210.

[0080] In this embodiment, only one take-up / unwind roller 320 may be provided to take up or unwind the material individually.

[0081] In other embodiments, two take-up and unwind rollers 320 may be provided, and respectively located upstream and downstream of the slitting mechanism 100 and the rolling mechanism 200, to perform material unwinding and material winding respectively.

[0082] In this embodiment, the take-up and release rollers 320 can be mounted on the third slide rail 310 via a support plate. The position of the take-up and release rollers 320 can be adjusted via the third slide rail 310 to adapt to the slitting mechanism 100 and the rolling mechanism 200.

[0083] In this embodiment, the take-up and release roller 320 may be connected to a seventh driving member. The seventh driving member can drive the take-up and release roller 320 to rotate.
