[0036] In one embodiment, as Figure 1 , Figure 3 and Figure 4 shown, a de-ironing device is provided, which includes a base 10, a carrier 20, a first magnetic attraction assembly 30 and a cover plate 40.

[0037] Among them, the winding machine can be used to wind the electrode sheet, and then a battery cell body can be prepared. The base 10 can be used to support the carrier 20, and the base 10 can also be used to be installed on a wall surface of the winding machine, so as to install the de-ironing device at the corresponding position of the winding machine.

[0038] The base 10 can be a base 10 made of metal. For example, the base 10 is made of metal and is a magnetizable base 10. A first mounting area 110 is provided on the base 10, and the first mounting area 110 is used for mounting on a winding machine. Exemplarily, mounting holes 112 are provided at a position of the winding machine adjacent to the pole piece winding. The first mounting area 110 is provided with mounting holes 112. The mounting holes 112 in the first mounting area 110 are arranged corresponding to the mounting holes 112 on the winding machine. Fasteners (such as bolts) can pass through the mounting holes 112 in the first mounting area 110 and the mounting holes 112 on the winding machine, so as to lock the base 10 at the corresponding position on the winding machine.

[0039] The carrier 20 is connected to the base 10 in a detachable manner. For example, the carrier 20 can be arranged on the base 10 by means of plugging, clamping, riveting or screwing. In another example, the carrier 20 can also be arranged on the base 10 by a combination of magnetic attraction and plugging, so as to facilitate the disassembly and assembly of the carrier 20. The shape of the carrier 20 can be, but is not limited to, regular shapes such as square or cylindrical, and the shape of the carrier 20 can also be an irregular shape. Exemplarily, the carrier 20 is integrally in a cuboid structure, and the first side of the carrier 20 is the side with a larger area of the carrier 20. A first magnetic attraction mounting area 210 is provided on the first side of the carrier 20, and the first magnetic attraction mounting area 210 can be used for mounting and setting the first magnetic attraction component 30.

[0040] Exemplarily, the first magnetic attraction component 30 can be arranged in the first magnetic attraction mounting area 210 by means of clamping or bonding. The first magnetic attraction component 30 can include several first magnetic attraction elements 310. For example, the first magnetic attraction component 30 can include at least 2 first magnetic attraction elements 310. The first magnetic attraction element 310 can be, but is not limited to, a permanent magnet. It should be noted that the number of the first magnetic attraction elements 310 can be determined according to the size of the carrier 20 and the specific model of the winding machine.

[0041] The cover plate 40 can be arranged on the carrier 20 by means of screwing or clamping. For example, at least one side of the cover plate 40 is provided with a first through hole, at least one side of the carrier 20 is provided with a second through hole. The first through hole of the cover plate 40 corresponds to the second through hole of the carrier 20.

When the iron removal device needs to be cleaned, by removing the corresponding fasteners, the cover plate 40 can be taken out, so as to clean the magnetic metal powder adsorbed by the first magnetic attraction component 30, improving the convenience of cleaning the iron removal device.

[0042] Exemplarily, the cover plate 40 can be a cover plate 40 made of a non-magnetic material. For example, the cover plate 40 can be a plastic cover plate 40. By covering the cover plate 40 on the first magnetic adsorption installation area 210, the isolation between the first magnetic adsorption assembly 30 in the first magnetic adsorption installation area 210 and the outside world is realized, avoiding the direct contact between the first magnetic adsorption assembly 30 and magnetic metal powder. Then, when cleaning is required, only the cover plate 40 needs to be disassembled, and the magnetic metal powder adsorbed by the first magnetic adsorption assembly 30 can be cleaned, improving the convenience of the cleaning operation of the iron removal device and saving the cleaning operation time.

[0043] In the above embodiment, the base 10 is provided with a first installation area 110; the first installation area 110 is used for installation on the winding machine; the carrier 20 is detachably connected to the base 10, and a first magnetic adsorption installation area 210 is provided on the first surface of the carrier 20; the first magnetic adsorption assembly 30 is arranged in the first magnetic adsorption installation area 210; the cover plate 40 is detachably arranged on the carrier 20, and the cover plate 40 is used to cover the first magnetic adsorption installation area 210, so as to be able to adsorb the magnetic metal on the surface of the electrode sheet and realize iron removal during the winding process of the electrode sheet.

[0044] In one embodiment, as Figure 2 and Figure 4 shown, the iron removal device further includes a guide rail member 50; the base 10 is further provided with a second installation area 120, the first end of the guide rail member 50 is arranged in the second installation area 120, and the second end of the guide rail member 50 is detachably connected to the carrier 20.

[0045] Among them, the guide rail member 50 can be used to guide the installation of the carrier 20 on the base 10, facilitating the fixing of the direction and position of the carrier 20 during disassembly and assembly. The guide rail member 50 can be in a cylindrical shape. In another example, the guide rail member 50 can also be in an elliptical cylindrical shape, etc.

[0046] The base 10 is further provided with a second installation area 120 for installing the guide rail member 50. Exemplarily, the second installation area 120 is provided with installation holes 112, and the first end of the guide rail member 50 can be inserted into the installation holes 112 of the second installation area 120 by an interference fit method, thereby realizing the installation of the guide rail member 50 on the base 10. The second end of the guide rail member 50 can be arranged on the carrier 20 by means of plugging or clamping, etc., to realize the detachable connection between the guide rail member 50 and the carrier 20, thereby facilitating the disassembly and assembly of the carrier 20.

[0047] Exemplarily, when the iron removal device needs to be cleaned, the carrier 20 can be first detached from the guide rail member 50, and then the cover plate 40 can be detached. Furthermore, the magnetic metal powder adsorbed by the first magnetic attraction assembly 30 can be transferred to a designated position for cleaning, improving the convenience of cleaning the iron removal device. When the iron removal device needs to be assembled, the cleaned cover plate 40 can be reinstalled on the carrier 20 to cover the first magnetic attraction installation area 210, and then the carrier 20 can be detachably connected to the guide rail member 50, thereby realizing the installation of the iron removal device, improving the convenience of disassembling and assembling the carrier 20, and simplifying the overall structure of the iron removal device.

[0048] In one embodiment, as Figure 2 and Figure 4 shown, a limiting groove 220 is provided on the second surface of the carrier 20; the second end of the guide rail member 50 is inserted into the limiting groove 220.

[0049] Among them, the second surface of the carrier 20 can be adjacent to the first surface. Exemplarily, the first surface of the carrier 20 can be the side surface with the largest area, and the second surface of the carrier 20 can be the side surface with the smallest area. A limiting groove 220 is provided on the second surface of the carrier 20, and the limiting groove 220 can be used to accommodate the guide rail member 50. The size and shape of the limiting groove 220 can be specifically determined according to the size and shape of the guide rail member 50.

[0050] Exemplarily, the second end of the guide rail member 50 can be set as a conical structure, thereby facilitating the insertion of the second end of the guide rail member 50 into the limiting groove 220 of the carrier 20. By arranging the first end of the guide rail member 50 in the second installation area 120 of the base 10 and inserting the second end of the guide rail into the limiting groove 220 of the carrier 20, when the iron removal device needs to be cleaned, the carrier 20 is pulled out from the guide rail member 50, so that the carrier 20 is separated from the guide rail member 50, and then the cover plate 40 is detached. Furthermore, the magnetic metal powder adsorbed by the first magnetic attraction assembly 30 can be transferred to a designated position for cleaning, improving the convenience of cleaning the iron removal device and simplifying the overall structure of the iron removal device.

[0051] In one embodiment, there is a gap between the inner wall of the limiting groove 220 and the guide rail member 50.

[0052] Among them, the gap can be a gap in millimeters. By setting a gap between the inner wall of the limiting groove 220 and the guide rail member 50, the inner diameter of the limiting groove 220 is made larger than the diameter of the guide rail member 50, facilitating the insertion of the second end of the guide rail member 50 into the limiting groove 220, thereby improving the convenience of disassembling and loading the carrier 20.

[0053] In one embodiment, the number of guide rail members 50 is at least 2, and the number of limiting grooves 220 is at least 2. Each limiting groove 220 is arranged in one-to-one correspondence with each guide rail member 50.

[0054] For example, the number of guide rail members 50 is 2. The 2 guide rail members 50 are divided into a first guide rail member and a second guide rail member; the number of limiting grooves 220 is 2. The 2 limiting grooves 220 are divided into a first limiting groove and a second limiting groove. The first guide rail member and the second guide rail member are arranged at intervals. The second end of the first guide rail member is used for movably inserting into the first limiting groove, and the second end of the second guide rail member is used for movably inserting into the second limiting groove. Exemplarily, the second installation area 120 of the base 10 includes a second installation hole and a third installation hole. The first end of the first guide rail member is used for fixedly inserting into the second installation hole, and the first end of the second guide rail member is used for fixedly inserting into the third installation hole.

[0055] When assembling the iron removal device, the cover plate 40 can be installed on the carrier 20 to cover the first magnetic adsorption installation area 210. Then, the limiting groove 220 of the carrier 20 can be aligned with the corresponding guide rail member 50, and the guide rail member 50 can be inserted into the corresponding limiting groove 220, thereby realizing the guiding installation of the carrier 20 on the base 10, facilitating the fixing of the direction and position of the carrier 20 during installation, improving the convenience of disassembling and loading the carrier 20, and simplifying the overall structure of the iron removal device. When cleaning the iron removal device, the guide rail member 50 is pulled out from the limiting groove 220 of the carrier 20, so that the guide rail member 50 is separated from the limiting groove 220. Then, the cover plate 40 is disassembled, and the magnetic metal powder adsorbed by the first magnetic adsorption component 30 can be transferred to a designated position for cleaning, improving the convenience of cleaning the iron removal device and simplifying the overall structure of the iron removal device.

[0057] Among them, the second magnetic attraction component 60 can be used to adsorb on the base 10, so that the vehicle 20 can be adsorbed on the base 10. The second magnetic attraction component 60 can include a plurality of second magnetic attraction members, and each second magnetic attraction member can be arranged in the second magnetic attraction installation area 230 by means of clamping or bonding. For example, the second magnetic attraction component 60 can include at least 2 second magnetic attraction members. The second magnetic attraction member can be, but is not limited to, a permanent magnet.

[0058] Exemplarily, the second magnetic attraction installation area 230 can be arranged between the first limiting groove and the second limiting groove; alternatively, the second magnetic attraction installation area 230 can include a second installation groove and a third installation groove. The second magnetic attraction component 60 can include 2 second magnetic attraction members. One first magnetic attraction member 310 is installed in the second installation groove, and the other first magnetic attraction member 310 is installed in the third installation groove. When assembling the iron removal device, the cover plate 40 can be installed on the vehicle 20 to cover the first magnetic attraction installation area 210. Then, the limiting groove 220 of the vehicle 20 can be aligned with the corresponding guide rail member 50, and the guide rail member 50 can be inserted into the corresponding limiting groove 220, so as to realize guiding the installation of the vehicle 20 on the base 10, facilitating the fixing of the direction and position during the installation of the vehicle 20. In addition, after the guide rail member 50 is inserted into the corresponding limiting groove 220, the second surface of the vehicle 20 can be attached to the base 10, so that the magnet can adsorb on the base 10, and the vehicle 20 and the base 10 are tightly combined. When the winding machine is running, the vehicle 20 can be prevented from falling off, and at the same time, the vehicle 20 is convenient to disassemble, improving the convenience of disassembling and installing the vehicle 20 and simplifying the overall structure of the iron removal device.

[0059] In one embodiment, as Figure 3 Figure 4 and Figure 5 shown, the first magnetic attraction installation area 210 is provided with at least 2 first installation grooves 212, and the first magnetic attraction component 30 includes at least 2 first magnetic attraction members 310; each first magnetic attraction member 310 is correspondingly arranged in each first installation groove 212.

[0061] For example, the first magnetic adsorption installation area 210 is provided with three first installation grooves 212, and the first magnetic adsorption assembly 30 includes three first magnetic adsorption members 310. Each first installation groove 212 can be arranged along the length direction of the first surface of the carrier 20, and two adjacent first installation grooves 212 communicate with each other and are arranged at intervals.

[0062] In one embodiment, the base 10 is a base 10 made of a magnetic material, and the carrier 20 is a carrier 20 made of a non-magnetic material.

[0063] For example, the base 10 can be a magnetic base 10 made of iron or a composite material, and the carrier 20 can be a non-magnetic carrier 20 made of plastic, aluminum or other materials. By setting the carrier 20 as a non-magnetic carrier 20, it is convenient to disassemble the first magnetic adsorption assembly 30 installed on the carrier 20; by making the base 10 a magnetic base 10, it is convenient for the second magnetic adsorption assembly 60 to adsorb on the base 10, enhancing the connection strength between the carrier 20 and the base 10.

[0064] In one embodiment, as Figure 4 and Figure 5 shown, the first installation area 110 is provided with at least two installation holes 112, and the installation holes 112 are in a long strip shape.

[0065] For example, the two ends of the installation hole 112 can be respectively provided with arc transitions, so that the installation hole 112 is in a runway shape. Each installation hole 112 is arranged at intervals. Exemplarily, the first installation area 110 is provided with three long strip-shaped installation holes 112, and the three installation holes 112 are arranged at intervals. The size of one of the installation holes 112 can be set to be larger than the sizes of the other two installation holes 112.
