[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] In the description of the present invention, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be glue injection inside two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following is combined with Figure 1-5 The coated cut sheet 100 according to the embodiment of the present invention is described.

[0028] like Figure 1 As shown, the coated cut sheet 100 according to the embodiment of the present invention includes a coated sheet 1 and a logo sticker 2 .

[0029] Among them, the coated sheet 1 has a plurality of pole segments 101 spaced apart along its length direction, and an identification segment 102 and a cutting segment 103 are provided between adjacent pole segments 101. The identification segment 102 and the cutting segment 103 are arranged side by side along the length direction of the coated sheet 1. In other words, the identification segment 102 is connected to one of the adjacent pole segments 101, and the cutting segment 103 is connected to the other of the adjacent pole segments 101.

[0030] The identification sticker 2 is disposed on the identification section 102 .

[0031] It can be understood that in the subsequent cutting process, in order to be able to cut the coated cut piece 100 in time after the identification sticker 2 is identified, the identification section 102 should be arranged downstream of the cutting section 103 in the conveying direction of the coated cut piece 100. In other words, the identification section 102 should pass through the detection component of the cutting device before the cutting section 103. In this way, after the detection component of the cutting device identifies the identification sticker 2 of the identification section 102, the cutting component of the cutting device can cut the coated cut piece 100 in time in the cutting section 103.

[0032] The coated cut sheet 100 of the embodiment of the present invention can expand the detection area of ​​the coated cut sheet 100 by setting the identification sticker 2 on the coated cut sheet 100. In the subsequent cutting process, it can avoid the identification sticker 2 exceeding the detection area of ​​the cutting device due to fluctuations generated during the transportation of the coated cut sheet 100, so that the detection component of the cutting device can accurately detect the identification sticker 2 and cut the coated cut sheet 100, and the problem of cutting failure caused by missed detection by the detection component will not occur, thereby greatly improving the cutting quality of the coated cut sheet 100.

[0033] Therefore, the coated cut piece 100 according to the embodiment of the present invention has the characteristics of being easy to identify and being able to greatly improve the cutting quality of the coated cut piece 100 .

[0034] In some embodiments, the ratio between the size of the logo sticker 2 in the width direction of the coated cut piece 100 and the size of the coated cut piece 100 in the width direction is 0.8-1.

[0035] By setting the ratio between the size of the identification sticker 2 in the width direction of the coated cut sheet 100 and the size of the coated cut sheet 100 in the width direction to 0.8-1, the detection area of ​​the coated cut sheet 100 can be greatly increased, making it easier for the detection component of the cutting device to perform detection.

[0036] Preferably, the ratio between the size of the logo sticker 2 in the width direction of the coated cut piece 100 and the size of the coated cut piece 100 in the width direction is 0.8.

[0037] The ratio between the dimension of the logo sticker 2 in the width direction of the coated cut piece 100 and the dimension of the coated cut piece 100 in the width direction is 0.9.

[0038] The ratio between the dimension of the logo sticker 2 in the width direction of the coated cut piece 100 and the dimension of the coated cut piece 100 in the width direction is 1.

[0039] In some embodiments, the center line of the logo sticker 2 in the width direction of the coated cut piece 100 coincides with the center line of the coated cut piece 100 in the width direction thereof.

[0040] By aligning the center line of the label sticker 2 in the width direction of the coated cut piece 100 with the center line of the coated cut piece 100 in the width direction thereof, it is possible to facilitate detection by the detection component of the cutting device.

[0041] In some embodiments, the identification sticker 2 is an insulating adhesive tape, and the insulating adhesive tape is different in color from the coating sheet 1 .

[0042] It can be understood that the coating sheet 1 is coated with an active material layer, for example, the positive electrode coating sheet 1 is coated with a positive electrode active material layer, and the negative electrode coating sheet 1 is coated with a negative electrode active material layer. By making the insulating tape and the coating sheet 1 different colors, it is possible to facilitate the detection component of the cutting device to detect the identification sticker 2. For example, the active material layer is usually black, and the identification sticker 2 can be set to white, red, etc. The specific setting method can be determined according to the detection component of the cutting device.

[0043] The present invention further provides a labeling device 200 for manufacturing the coated cut piece 100 described in the above embodiment.

[0044] like Figure 2 As shown, the labeling device 200 of the embodiment of the present invention includes a first conveying component 3 and a second conveying component 4.

[0045] like Figure 2 As shown, the first conveying assembly 3 is used to convey the coated sheet 1. The first conveying assembly 3 includes a pasting roller 301. The coated sheet 1 passes around the pasting roller 301. The pasting roller 301 is provided with an encoder 3011 to measure the length of the coated sheet 1 conveyed by the pasting roller 301.

[0046] like Figure 2 As shown, the second conveying assembly 4 is used to convey an adhesive film 5 with a logo sticker 2 on one side.

[0047] like Figure 5 As shown, a plurality of identification stickers 2 are arranged on the adhesive film 5 , and the plurality of identification stickers 2 are arranged at intervals in the length direction of the adhesive film 5 .

[0048] The second conveying component 4 includes an adhesive sheet 401 arranged adjacent to the adhesive roller 301 , and the adhesive film 5 is wound around the adhesive sheet 401 . The adhesive sheet 401 is used to separate the identification sticker 2 and the adhesive film 5 , and to adhere the identification sticker 2 to the identification section 102 of the coating sheet 1 to form a coated cut sheet 100 .

[0049] Specifically, the adhesive sheet 401 has a first side surface 4011 and a second side surface 4012 opposite to each other in the thickness direction thereof, and an adhesive end 4013 connecting the first side surface 4011 and the second side surface 4012; The side of the adhesive film 5 provided with the identification sticker 2 faces away from the adhesive sheet 401; The adhesive film 5 is introduced from the side of the adhesive sheet 401 having the first side 4011 , and after passing through the adhesive end 4013 to separate the identification sticker 2 and the adhesive film 5 and to adhere the identification sticker 2 to the identification section 102 of the coating sheet 1 , is led out from the side of the adhesive sheet 401 having the second side 4012 .

[0050] It can be understood that when the adhesive film 5 passes around the adhesive end 4013 of the adhesive film 401, the adhesive film 5 is bent, and thus the identification sticker 2 provided on the adhesive film 5 begins to curl up. As the adhesive film 5 moves, the identification sticker 2 is gradually separated from the adhesive film 5, and the part of the identification sticker 2 separated from the adhesive film 5 moves toward the coating sheet 1 on the adhesive roller 301 at the same time, and the identification sticker 2 moves synchronously with the coating sheet 1, and then the identification sticker 2 is adhered to the identification section 102 of the coating sheet 1.

[0051] In some embodiments, the second conveying assembly 4 further includes an auxiliary roller 6, such as Figure 2 and 3 As shown, the auxiliary roller 6 can move between a first position abutting against the pasting roller 301 and a second position detached from the pasting roller 301. When the auxiliary roller 6 is in the first position, the auxiliary roller 6 cooperates with the pasting roller 301 to roll the identification sticker 2 on the coating sheet 1.

[0052] Furthermore, a driving member may be provided to drive the auxiliary roller 6 to move between the first position and the second position.

[0053] After the identification sticker 2 is pasted to the identification section 102 of the coating sheet 1, the driving member drives the auxiliary roller 6 to move from the second position to the first position. When in the first position, the auxiliary roller 6 abuts against the identification sticker 2 on the coating sheet 1 on the pasting roller 301 and rotates synchronously with the pasting roller 301. When the identification sticker 2 pasted on the coating section of the coating sheet 1 passes through the auxiliary roller 6, the auxiliary roller 6 rolls the identification sticker 2 so that it can be more firmly pasted on the coating sheet 1.

[0054] In some embodiments, Figure 2 As shown, the first conveying assembly 3 further includes a first unwinding roller 302 and a first winding roller 303 ; the first unwinding roller 302 is used for unwinding the coated sheet 1 ; the first winding roller 303 is used for winding the coated cut sheet 100 .

[0055] The labeling device 200 of the embodiment of the present invention is provided with a first unwinding roller 302 and a first winding roller 303. On the one hand, the first unwinding roller 302 can be used to place the coated sheet 1 and unwind the coated sheet 1, and on the other hand, the first winding roller 303 can be used to place the coated cut sheet 100 and wind up the prepared coated cut sheet 100.

[0056] In some embodiments, Figure 2 As shown, the second conveying assembly 4 further includes a second unwinding roller 402 and a second winding roller 403 ; the second unwinding roller 402 is used for unwinding the adhesive film 5 provided with the identification sticker 2 ; the first winding roller 303 is used for winding the adhesive film 5 not provided with the identification sticker 2 .

[0057] The labeling device 200 of the embodiment of the present invention is provided with a second unwinding roller 402 and a second winding roller 403. On the one hand, the second unwinding roller 402 can be used to place the adhesive film 5 with the identification sticker 2 and unwind the adhesive film 5 with the identification sticker 2, and on the other hand, the second winding roller 403 can be used to place the adhesive film 5 without the identification sticker 2 and wind up the adhesive film 5 without the identification sticker 2.

[0058] The embodiment of the present invention further provides a method for manufacturing the coated cut sheet 100 of the above embodiment using the device of the above embodiment.

[0059] The method of the embodiment of the present invention comprises the following steps: Step S100: using the encoder 3011 disposed on the pasting roller 301 to obtain whether the conveying length of the coated sheet 1 reaches a preset value to determine whether the identification section 102 of the coated sheet 1 corresponds to the pasting sheet 401; Step S200: If the identification section 102 of the coating sheet 1 corresponds to the adhesive sheet 401, step S300 is executed: If the identification section 102 of the coating sheet 1 does not correspond to the adhesive sheet 401, step S100 is executed; Step S300 : controlling the second conveying assembly 4 to adhere the identification sticker 2 of the adhesive film 5 to the identification section 102 of the coated sheet 1 to form the coated cut sheet 100 .

[0060] It can be understood that in step S200, when the identification segment 102 of the coated sheet 1 corresponds to the adhesive sheet 401, that is, the conveying distance of the coated sheet 1 reaches the preset value, step S300 is executed to control the second conveying component 4 to stick the identification sticker 2 of the adhesive film 5 to the identification segment 102 of the coated sheet 1 to form a coated cut sheet 100; when the identification segment 102 of the coated sheet 1 does not correspond to the adhesive sheet 401, step S100 is executed, that is, the encoder 3011 provided on the pasting roller 301 is used to obtain again whether the conveying length of the coated sheet 1 reaches the preset value to determine whether the identification segment 102 of the coated sheet 1 corresponds to the adhesive sheet 401, and then step S200 is executed to realize real-time determination of whether the identification segment 102 of the coated sheet 1 corresponds to the adhesive sheet 401, which can greatly improve the labeling accuracy of the labeling method of the embodiment of the present invention and avoid the problem of missing labeling.

[0061] The present invention further provides a cutting device 300 for cutting the coated cut pieces as described in the above embodiment.

[0062] like Figure 6 As shown, the cutting device of the embodiment of the present invention includes a control device 8, a third conveying component 7, a detection component 9 and a cutting component 10.

[0063] Among them, the third conveying component 7 includes multiple conveying rollers for conveying the coated cut pieces, and the third conveying component 7 is connected to the control device 8; the detection component 9 is used to detect the identification sticker 2 of the identification segment 102, and the detection component 9 is connected to the control device 8; the cutting component 10 is connected to the control device 8 to cut the cutting segment 103 adjacent to the identification segment 102 after the detection component 9 detects the identification sticker 2 of the identification segment 102.

[0064] It can be understood that when the detection component 9 detects the identification sticker 2 of the identification segment 102, it will send a cutting signal to the control device 8. After receiving the cutting signal, the control device 8 controls the conveying roller of the third conveying component 7 to stop, so that the cutting segment 103 adjacent to the detected identification segment 102 stops at the cutting position of the cutting component 10, and the control device 8 controls the cutting device to perform cutting. After the cutting is completed, the conveying roller of the third conveying component 7 restarts, and the detection device restarts the detection, thereby reciprocating to achieve continuous cutting of the coated cutting piece.

[0065] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
