Description

Technical Field

[0001] This utility model relates to the field of electrode processing technology, and in particular to an electrode iron removal device. Background Technology

[0002] In the production process of lithium-ion batteries, positive and negative electrode sheets (collectively referred to as "electrodes") are important raw materials. Electrodes are made of metal foil as the substrate, with a paste coated on both sides of the substrate. During the cutting and conveying of electrode sheets, iron filings may adhere to the surface of the electrode sheets. If the iron filings are rolled into the inside of the battery cell, they can easily puncture the separator, leading to short circuits and thermal runaway problems in the battery cell.

[0003] Existing technology uses a fixed magnetic rod design to adsorb and remove iron filings from the surface of the electrode. However, the magnetic rod needs to be manually disassembled and the iron filings removed periodically. Cleaning the iron filings on the magnetic rod is difficult, and the electrode conveying operation stops during disassembly and cleaning, making it impossible to continuously remove iron filings and resulting in low work efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that manually disassembling the magnetic rod periodically and removing the iron filings on it is difficult, and the electrode plates stop conveying during disassembly and cleaning, making it impossible to continuously remove the iron filings and resulting in low work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a technical solution for an electrode iron removal device: An electrode iron removal device, having a first orientation, includes: A rotary actuator includes a drive unit having a rotation axis extending along the first direction; A bracket is fixedly installed on the drive unit, and the bracket has a first mounting portion and a second mounting portion arranged symmetrically about the rotation axis. The first magnetic attraction structure includes a first base and a first isolation member. The first base is detachably connected to the first mounting part, and the first isolation member is detachably installed on the side of the first base away from the bracket. The first isolation member extends parallel to the rotation axis. The second magnetic structure is symmetrically arranged with respect to the bracket with respect to the first magnetic structure. The second magnetic structure includes a second base and a second isolator. The second base is detachably connected to the second mounting part, and the second isolator is detachably installed on the side of the second base away from the bracket.

[0006] Furthermore, the first mounting part is provided with a first guide rail extending along the first direction, and the first base is provided with a first slot on the side near the bracket. The first slot and the first guide rail are guided and engaged along the first direction; along the direction away from the bracket from the first base, the first slot and the first guide rail are engaged in a blocking engagement.

[0007] Furthermore, it also has a second direction and a third direction, with the first direction perpendicular to the second direction and the third direction; along the third direction, the cross-sectional dimension of the first guide rail is D1, and the opening dimension of the first slot is D2; along the second direction and in the direction away from the bracket from the first base, both D1 and D2 are increased.

[0008] Furthermore, the first magnetic attraction structure also includes a first sliding groove, which is disposed on the side of the first base away from the bracket. The first sliding groove extends parallel to the rotation axis, and the first isolation member is inserted and installed in the first sliding groove.

[0009] Furthermore, both the first isolation member and the second isolation member are isolation plates. The first isolation member has a first stop edge on the side close to the rotary driver along the first direction, and the first stop edge protrudes towards the side away from the bracket.

[0010] Furthermore, the first isolation member is provided with a first handle on the side away from the rotary driver along the first direction.

[0011] Furthermore, the first magnetic attraction structure also includes a first magnet, the first base has a first insertion hole, the first magnet is inserted and installed in the first insertion hole, and the first magnet and the first isolation member are arranged at intervals.

[0012] Furthermore, the bracket is also provided with a first sensor and a second sensor, the first sensor and the first magnetic structure being arranged opposite to each other along the first direction; the second sensor and the second magnetic structure being arranged opposite to each other along the first direction.

[0013] Furthermore, the bracket includes a seat plate and a support portion. The seat plate is arranged perpendicular to the first direction, and the support portion extends along the first direction and is fixedly connected to the seat plate. The first mounting portion and the second mounting portion are symmetrically arranged on both sides of the support portion.

[0014] Furthermore, the rotary actuator is a rotary cylinder, and the rotary cylinder has a rotation angle stroke of 180°.

[0015] Compared with existing technologies, the present invention provides an electrode iron removal device with the following advantages: The device employs a design comprising a rotary driver, a support, a first magnetic attraction structure, and a second magnetic attraction structure. The rotary driver has a driving part with a rotation axis extending along a first direction. The support is fixedly installed on the driving part. The first and second magnetic attraction structures are symmetrically arranged on the support. A first isolation member is detachably installed on the side of the first base away from the support, and a second isolation member is detachably installed on the side of the second base away from the support. The first and second isolation members extend parallel to the rotation axis, allowing iron filings to be evenly adsorbed onto the flat surface of the isolation members, facilitating subsequent iron filings removal.

[0016] During operation, if the first magnetic attraction structure is close to and spaced apart from the electrode, it attracts and removes iron filings from the electrode during transport. At this time, the second magnetic attraction structure is in a standby position away from the electrode. When a large amount of iron filings accumulates on the first isolator of the first magnetic attraction structure, the rotating bracket is rotated by a rotary driver to interchange the positions of the two magnetic attraction structures. The first magnetic attraction structure is switched to the standby position, avoiding interference with the electrode during disassembly and facilitating the removal of the first isolator for quick cleaning of surface iron filings. The second magnetic attraction structure is then switched to a position closer to the electrode to continue attracting and removing iron filings.

[0017] Compared to existing technologies where iron filings are directly adsorbed onto magnetic rods, this solution features a detachable separator that facilitates iron filings removal. When the separator is removed, the iron filings adsorbed on the magnetic structure surface automatically fall off, reducing the difficulty of cleaning. The rotary driver can rotate the two magnetic structures to switch positions, ensuring that one magnetic structure is always in the iron-removing state during electrode conveying. Disassembly and cleaning do not affect electrode conveying, guaranteeing continuous iron filings removal from the electrode iron removal device. This avoids the need for manual periodic removal of magnetic rods to clean iron filings, reducing the frequency and workload of manual operations and improving work efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention provides an electrode iron removal device with a first direction X, comprising: a rotary driver 1, a bracket 2, a first magnetic attraction structure 3, and a second magnetic attraction structure 4. The rotary driver 1 includes a driving part 11, which has a rotation axis 10 extending along the first direction X. The bracket 2 is fixedly installed on the driving part 11 and has a first mounting part 21 and a second mounting part 22, which are symmetrically arranged about the rotation axis 10.

[0024] The first magnetic attraction structure 3 includes a first base 31 and a first isolation member 32. The first base 31 is detachably connected to the first mounting part 21, and the first isolation member 32 is detachably installed on the side of the first base 31 away from the bracket 2. The first isolation member 32 extends parallel to the rotation axis 10. The second magnetic attraction structure 4 is symmetrically arranged with respect to the first magnetic attraction structure 3 about the bracket 2. The second magnetic attraction structure 4 includes a second base 41 and a second isolation member 42. The second base 41 is detachably connected to the second mounting part 22, and the second isolation member 42 is detachably installed on the side of the second base 41 away from the bracket 2.

[0025] The electrode iron removal device adopts a design consisting of a rotary driver 1, a bracket 2, a first magnetic attraction structure 3, and a second magnetic attraction structure 4. The rotary driver 1 has a driving part 11 with a rotation axis 10 extending along a first direction X. The bracket 2 is fixedly installed on the driving part 11. The first magnetic attraction structure 3 and the second magnetic attraction structure 4 are symmetrically arranged on the bracket 2. The first isolation member 32 is detachably installed on the side of the first base 31 away from the bracket 2, and the second isolation member 42 is detachably installed on the side of the second base 41 away from the bracket 2. The first isolation member 32 and the second isolation member 42 extend parallel to the rotation axis 10, which can evenly adsorb iron filings onto the flat surface of the isolation member, facilitating subsequent iron filings cleaning.

[0026] During operation, if the first magnetic structure 3 is close to and spaced apart from the electrode 5, it attracts and removes iron filings from the electrode 5 during its conveying process. At this time, the second magnetic structure 4 is in a standby position away from the electrode 5. When a large amount of iron filings are attracted to the first isolator 32 of the first magnetic structure 3, the two magnetic structures are interchanged by rotating the bracket 2 through the rotary driver 1. The first magnetic structure 3 is switched to the standby position, avoiding interference with the electrode 5 during disassembly and facilitating the disassembly of the first isolator 32 of the first magnetic structure 3 to quickly clean the surface iron filings. At this time, the second magnetic structure 4 is switched to a position close to the electrode 5 to continue attracting and removing iron filings.

[0027] Compared to existing technologies where iron filings are directly adsorbed onto the magnetic rod, this solution features a detachable isolator that facilitates iron filings removal. When the isolator is removed, the iron filings adsorbed on the surface of the magnetic structure automatically fall off, reducing the difficulty of cleaning. The rotary driver 1 can rotate the two magnetic structures to switch positions, ensuring that one magnetic structure is always in the iron-removing state during the electrode 5's conveying operation. Disassembly and cleaning do not affect the conveying operation of electrode 5, guaranteeing that the electrode 5 iron removal device can continuously remove iron filings. This avoids the need for manual periodic removal of the magnetic rod to clean iron filings, reducing the frequency and workload of manual operation and improving work efficiency.

[0028] In this embodiment, the first mounting part 21 is provided with a first guide rail 210 extending along the first direction X, and a first slot 311 is provided on the side of the first base 31 near the bracket 2. The first slot 311 and the first guide rail 210 are guided and engaged along the first direction X; along the direction away from the bracket 2, the first slot 311 and the first guide rail 210 are stopped and engaged. Correspondingly, the second mounting part 22 is provided with a second guide rail 220 extending along the first direction X, and a second slot 411 is provided on the side of the second base 41 near the bracket 2. The second slot 411 and the second guide rail 220 are guided and engaged along the first direction X; along the direction away from the bracket 2, the second slot 411 and the second guide rail 220 are stopped and engaged. The combination of guiding and stopping engagement between the first slot 311 and the first guide rail 210, and between the second slot 411 and the second guide rail 220, ensures the convenience of disassembly and assembly and the reliability of installation of the two bases.

[0029] The electrode iron removal device also has a second direction Y and a third direction Z. The first direction X is perpendicular to both the second direction Y and the third direction Z. Along the third direction Z, the cross-sectional dimension of the first guide rail 210 is D1, and the opening dimension of the first slot 311 is D2. Along the second direction Y, and in the direction away from the support 2 of the first base 31, both D1 and D2 are increased. Along the direction away from the support 2 of the first base 31, the cross-sectional dimension D1 of the first guide rail 210 is increased to an isosceles trapezoid, and the opening dimension D2 of the first slot 311 is increased to a trumpet shape. The shapes and dimensions of the two are matched to prevent assembly from falling off. Since the second base 41 and the first base 31 are symmetrically arranged about the support 2, the shape and dimension matching design of the second guide rail 220 and the second slot 411 can refer to the above matching design, and will not be repeated here.

[0030] The first magnetic attraction structure 3 further includes a first sliding groove 33, which is located on the side of the first base 31 away from the support 2. The first sliding groove 33 extends parallel to the rotation axis 10, and the first isolation member 32 is inserted into the first sliding groove 33. Correspondingly, the second isolation member 42 is also assembled by sliding insertion. Both the first isolation member 32 and the second isolation member 42 are isolation plates. The first isolation member 32 has a first stop 321 on the side of the first isolation member 32 near the rotary driver 1 along the first direction X, and the first stop 321 protrudes towards the side away from the support 2. Furthermore, the first isolation member 32 has a first handle 322 on the side of the first isolation member 32 away from the rotary driver 1 along the first direction X.

[0031] The first isolation member 32 can be pulled out of the first slide groove 33 by the first handle 322. During the pulling process, the iron filings adhering to the surface of the first isolation member 32 are scraped off and collected, making it easier to clean the iron filings. Correspondingly, the second isolation member 42 has a second baffle 421 on the side of the first direction X near the rotary driver 1. The second baffle 421 protrudes away from the bracket 2. The second isolation member 42 has a second handle 422 on the side of the second isolation member 42 away from the rotary driver 1 in the first direction X. Similarly, the iron filings adhering to the surface of the second isolation member 42 can be quickly collected and cleaned.

[0032] As a further preferred embodiment, the first magnetic attraction structure 3 also includes a first magnet 34. The first base 31 has a first insertion hole 312, and the first magnet 34 is inserted into the first insertion hole 312. The first magnet 34 and the first isolator 32 are arranged at intervals. Furthermore, the bracket 2 is also equipped with a first sensor 23 and a second sensor 24. The first sensor 23 is arranged opposite to the first magnetic attraction structure 3 along the first direction X, and is used to detect whether the first magnetic attraction structure 3 is installed. The second sensor 24 is arranged opposite to the second magnetic attraction structure 4 along the first direction X, and is used to detect whether the second magnetic attraction structure 4 is installed. By sensing the first magnet 34 of the first magnetic attraction structure 3 with the first sensor 23, and sensing the second magnet of the second magnetic attraction structure 4 with the second sensor 24, it is determined whether the two magnetic attraction structures are properly installed on the bracket 2, thereby improving the stability of magnetic attraction and iron removal.

[0033] Additionally, the bracket 2 includes a base plate 25 and a support portion 26. The base plate 25 is arranged perpendicular to the first direction X, and the support portion 26 extends along the first direction X and is fixedly connected to the base plate 25. The first mounting portion 21 and the second mounting portion 22 are symmetrically arranged on both sides of the support portion 26. Furthermore, the rotary driver 1 is a rotary cylinder 12 with a rotation angle stroke of 180°. That is, when the rotary cylinder rotates at 0°, the first magnetic attraction structure 3 approaches the pole piece 5 to adsorb and remove iron filings. After working for a period of time, when a large amount of iron filings are adsorbed on the surface of the first isolation member 32, the rotary cylinder 12 is controlled to rotate to 180°, so that the second magnetic attraction structure 4 approaches the pole piece 5 to adsorb and remove iron filings. After working for a period of time, when a large amount of iron filings are adsorbed on the surface of the second isolation member 42, the rotary cylinder 12 is controlled to rotate back to 0°, and the above process is repeated.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
