[0002] In the lithium battery electrode production process, the electrode sheets are transported between various workstations via conveyor belts and undergo different processing steps.

[0049] The following is combined Figures 1-7 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] In a first aspect, the present invention provides a cleaning mechanism for an electrode conveyor belt, comprising an abutting component and a friction cleaning component; the electrode conveyor belt 3 passes between the abutting component and the friction cleaning component; the abutting component is fixedly disposed and abuts against a first surface of the electrode conveyor belt 3; the friction cleaning component is movably disposed and abuts against a second surface of the electrode conveyor belt 3, and the friction cleaning component rotates and rubs against the second surface of the electrode conveyor belt 3.

[0051] In this embodiment, the friction cleaning component abuts against the second side of the electrode conveyor belt 3, namely the electrode bearing surface, and friction is generated between the component and the electrode bearing surface of the electrode conveyor belt 3 to remove impurity particles on the electrode conveyor belt 3.

[0052] Specifically, in this embodiment, the abutting component abuts against the electrode conveyor belt 3 from the first side, i.e. the inner side, while the friction cleaning component abuts against the electrode bearing surface of the electrode conveyor belt 3, forming rotational friction. This achieves rigid contact between the friction cleaning component and the electrode conveyor belt 3, which can forcibly remove impurity particles adhering to the electrode conveyor belt 3, preventing impurity particles on the conveyor belt from adhering to the electrode surface. This improves the flatness of the module after electrode stacking and the voltage test yield, thereby improving the battery yield.

[0053] In this embodiment, regardless of how the electrode conveyor belt 3 moves longitudinally, the abutment component can provide a constant reaction force reference system in the lateral dimension, so that all subsequent cleaning actions occur on a stable and repeatable contact line, that is, the position of the abutment component and the friction cleaning component.

[0054] In this embodiment, the contact component, the electrode conveyor belt 3, and the friction cleaning component are equivalent to forming a three-segment energy transfer chain of "rigid-flexible-rigid": the rigid contact surface of the contact component provides normal constraint; the flexible electrode conveyor belt 3 generates slight elastic deformation under normal constraint; and the movable friction cleaning component applies tangential relative motion.

[0055] In this embodiment, the friction between the friction cleaning component and the electrode conveyor belt 3 can be either that the friction cleaning component remains stationary while the electrode conveyor belt 3 moves, resulting in relative friction, or that the friction cleaning component moves at a different speed than the electrode conveyor belt 3, resulting in relative friction.

[0056] In an optional embodiment, a cleaning box 2 is also included; the abutting component is fixedly disposed on the inner wall of the cleaning box 2; the friction cleaning component is movably disposed in the cleaning box 2; and the cleaning box 2 is provided with a belt passage gap 5 for the electrode conveyor belt 3 to pass through.

[0057] In this embodiment, the cleaning box 2 effectively protects the contact component and the friction cleaning component, while also effectively collecting the impurity particles after friction cleaning. This avoids the impact of the external environment on the contact component and the friction cleaning component, and effectively protects the environment by preventing the pollution of the environment by impurity particles.

[0058] Specifically, in this embodiment, the front and rear walls of the cleaning box 2 are provided with a through-slot 5, and the electrode conveyor belt 3 naturally forms a three-section path of "inlet-cavity-outlet" when passing through the through-slot.

[0059] More specifically, in this embodiment, the width of the belt gap 5 is greater than the thickness of the electrode conveyor belt 3, which can ensure the smooth passage of the electrode conveyor belt 3 through the belt gap 5.

[0060] In this embodiment, the abutment component is fixed inside the housing and located at the upper part of the internal cavity. The friction cleaning component is suspended at the lower part of the internal cavity of the cleaning box 2, and the space between the two becomes the "impurity capture zone". Due to the obstruction of airflow by the housing, a local static pressure environment is formed inside the cavity, and the particles are not easily diffused outward after being peeled off, thus being collected at the lower part of the cleaning box 2.

[0061] In this embodiment, the cleaning box 2 confines the cleaned impurity particles within a controllable volume to avoid secondary contamination of the surrounding electrode sheets.

[0062] In an optional embodiment, the abutting component includes an abutting roller 9; the two ends of the abutting roller 9 are fixed to the side wall of the cleaning box 2, and the outer wall of the abutting roller 9 makes rolling contact with the first surface of the electrode conveyor belt 3.

[0063] In this embodiment, the two ends of the abutment roller 9 are rotatably mounted on the two side walls of the cleaning box 2 and abut against the electrode conveyor belt 3, forming a passive rotating shaft that can rotate synchronously with the electrode conveyor belt 3. The outer wall of the abutment roller 9 maintains rolling contact with the first surface of the electrode conveyor belt 3, rather than sliding contact. Since the abutment roller 9 can rotate, the relative speed difference between the outer surface of the abutment roller 9 and the belt surface of the electrode conveyor belt 3 approaches zero, forming a rolling support pair.

[0064] Specifically, in this embodiment, the two ends of the abutment roller 9 are connected to the inner wall of the cleaning box 2 through bearings to ensure the rotational stability of the abutment roller 9, reduce the friction generated when the abutment roller 9 rotates, and extend the service life between the abutment roller 9 and the cleaning box 2.

[0065] In this embodiment, the rolling contact between the abutment roller 9 and the electrode conveyor belt 3 transforms the line contact between them into a surface contact. During long-term operation, different areas of the outer surface of the abutment roller 9 alternately contact the belt surface of the electrode conveyor belt 3, resulting in uniform wear distribution and preventing cleaning failure due to localized grooves. Simultaneously, the rolling contact produces a micro-rolling and flattening effect on the belt surface of the electrode conveyor belt 3, smoothing out tiny wrinkles and improving the uniformity of friction cleaning.

[0066] In this embodiment, the axis of the contact roller 9 is perpendicular to the running direction of the electrode conveyor belt 3.

[0067] In an optional embodiment, the friction cleaning assembly includes a movable frame 11, a friction roller 10, a rotation drive 6, and a lifting drive 8; the friction roller 10 is disposed on the movable frame 11, and the movable frame 11 is disposed inside the cleaning box 2; the rotation drive 6 is disposed on the movable frame 11, and the rotation drive 6 is connected to the end of the friction roller 10, and the rotation drive 6 can drive the friction roller 10 to rotate; the lifting drive 8 is connected to the movable frame 11, and the lifting drive 8 can drive the movable frame 11 to move up and down.

[0068] In this embodiment, the movable frame 11 can move up and down within the cleaning box 2, thereby adjusting the gap between the friction roller 10 and the abutment roller 9 to achieve the purpose of rubbing and removing impurity particles from the electrode bearing surface of the electrode conveyor belt 3; the friction roller 10 is mounted on the movable frame 11 and can rotate around its own axis; the rotation drive 6 is coaxially connected to the friction roller 10 to provide power for the rotation of the friction roller 10; the lifting drive 8 is connected to the movable frame 11 and can drive the movable frame 11 to move up and down in the vertical direction.

[0069] Specifically, in this embodiment, the lifting stroke of the moving frame 11 determines the depth of contact between the friction roller 10 and the surface of the electrode conveyor belt 3, and thus determines the cleaning intensity.

[0070] Specifically, in this embodiment, the friction roller 10 removes impurity particles from the electrode conveyor belt 3 by rotating at different speeds with or in the opposite direction to the electrode conveyor belt 3.

[0071] Specifically, in this embodiment, the power source for the rotation drive 6 is a motor, and the output shaft of the motor is fixedly connected to one end of the friction roller 10, which can drive the friction roller 10 to rotate at a set speed.

[0072] Specifically, in this embodiment, the lifting drive 8 consists of multiple cylinders. The multiple cylinders can extend and retract synchronously, thereby driving the moving frame 11 to rise and fall. The friction roller 10 and the rotation drive 6 are both mounted on the moving frame 11. Under the action of the cylinders, they can rise and fall synchronously, thereby driving the friction roller 10 to move closer to or away from the electrode bearing surface of the electrode conveyor belt 3.

[0073] Specifically, in this embodiment, the surface of the friction roller 10 is a felt layer, and the electrode conveyor belt 3 is a steel belt. The softness and elasticity of the felt layer itself can closely adhere to the surface of the steel belt while avoiding scratching the steel belt, thus achieving excellent friction cleaning effect.

[0074] More specifically, in this embodiment, the cylinder can be located inside the cleaning box 2 or outside the cleaning box 2, depending on the specific usage environment.

[0075] When using it, first start the lifting drive 8 so that the surface of the friction roller 10 lightly touches the surface of the electrode conveyor belt 3, and then start the rotation drive 6 to observe the peeling effect; if there are still residues, the micro-lifting moving frame 11 will intervene more deeply until no particles are visible to the naked eye.

[0076] It is understood that in this embodiment, the lifting drive component 8 is a cylinder, but it is not limited to a cylinder. It can also be a hydraulic cylinder or an elastic component such as a spring, as long as it can apply a force to the moving frame 11 in the direction of the electrode conveyor belt 3.

[0077] In an optional embodiment, the inner wall of the cleaning box 2 is provided with a guide rail 13; the movable frame 11 is slidably connected to the cleaning box 2 through the guide rail 13.

[0078] In this embodiment, a guide rail 13 is provided on the inner wall of the cleaning box 2. The moving frame 11 can form a sliding pair with the cleaning box 2 through the guide rail 13, which ensures the stability of the moving frame 11 when it is raised and lowered in the vertical direction and avoids shaking and swaying.

[0079] In this embodiment, the guide rail 13 is set vertically.

[0080] Specifically, in this embodiment, the guide rail 13 may be a guide groove provided on the inner wall of the cleaning box 2, and matching guide blocks provided at both ends of the moving frame 11, thereby forming a guide structure for the moving frame 11.

[0081] It is understandable that the guide rail 13 can be configured in many ways, not just limited to the cooperation of the guide groove and guide block mentioned above. It can also be configured by setting a sliding groove on the inner wall of the cleaning box 2 and setting rollers at both ends of the moving frame 11, with the rollers rolling in the sliding groove to limit the movement of the moving frame 11. In other words, as long as the guide rail 13 can be formed to limit the trajectory of the moving frame 11 during lifting and lowering, it is acceptable.

[0082] In an optional embodiment, the rotating drive 6 is covered with a dust cover; the side wall of the cleaning box 2 has a perforated opening 14 for the dust cover to move.

[0083] In this embodiment, the rotating drive component 6 is placed inside a dust cover. The dust cover effectively protects the rotating drive component, preventing external dust and debris from adversely affecting it, and also preventing external dust and debris from entering the cleaning box 2.

[0084] In this embodiment, the cleaning box 2 has a hollow opening 14 on its side wall, which forms a sliding groove, so that the dust cover can slide up and down in the hollow opening 14 on the side wall of the cleaning box 2 along with the rotating drive component 6, thereby maintaining effective protection for the rotating drive component.

[0085] In an optional embodiment, an extraction box 4 is also included; the extraction box 4 is disposed at the bottom of the cleaning box 2 and is disposed corresponding to the moving frame 11, for receiving impurity particles that fall onto the moving frame 11 after the friction cleaning assembly performs friction cleaning on the electrode conveyor belt 3; the extraction box 4 is connected to an external vacuum device for extracting the impurity particles in the extraction box 4.

[0086] In this embodiment, the extraction box 4 is located at the bottom of the cleaning box 2 and is perpendicular to the moving frame 11.

[0087] Specifically, in this embodiment, the movable frame 11 has an inclined surface 12 located below the friction roller 10, so that the impurity particles removed from the electrode conveyor belt 3 by the friction roller 10 fall onto the inclined surface 12. One side of the extraction box 4 has an opening corresponding to the inclined surface 12, allowing the impurity particles on the inclined surface 12 to flow into the extraction box 4 under the influence of gravity and be collected there.

[0088] In this embodiment, the extraction box 4 can be configured as a drawer-type structure. That is, when the amount of impurity particles in the extraction box 4 is large, the extraction box 4 can be extracted, the impurity particles can be uniformly processed and then put back, or the extraction box 4 can be extracted and replaced with a new extraction box 4.

[0089] In this embodiment, a vacuum device, such as a vacuum pump, can be connected to the end or bottom of the extraction box 4 to create a negative pressure outside the extraction box 4. Under the action of the negative pressure, the impurity particles inside the extraction box 4 can be sucked up, thereby achieving the purpose of cleaning the impurity particles inside the extraction box 4.

[0090] As can be seen from the above, the extraction box 4 provided in this embodiment has multiple functions. The first function is particle aggregation: that is, the inclined surface 12 of the moving frame 11 guides the stripped impurity particles to the opening of the extraction box 4, preventing the particles from scattering around the bottom of the cleaning box 2; the second function is negative pressure extraction: the negative pressure in the extraction box 4 accelerates the suction of particles, preventing secondary dust; the third function is offline cleaning: when the impurity particles in the extraction box 4 accumulate to a certain height, the extraction box 4 can be directly extracted for offline dumping without stopping the electrode conveyor belt 3.

[0091] In an optional embodiment, the top of the cleaning box 2 is provided with an openable and closable cover plate 7; the cover plate 7 covers the abutment component.

[0092] In this embodiment, the shielding cover 7 is disposed on the top of the cleaning box 2, and the connection between the cover 7 and the cleaning box 2 is a bolt connection.

[0093] Specifically, in this embodiment, the shielding cover 7 is a shell-shaped structure that covers the abutting component. The shielding cover 7 can be disassembled to facilitate the installation and maintenance of the abutting component. At the same time, the shielding cover 7 can effectively protect the abutting component and prevent the external environment from causing adverse interference to the abutting component.

[0094] It is understood that in this embodiment, the connection between the shielding cover 7 and the cleaning box 2 is a bolt connection, but it is not limited to bolt connection. It can also be other connection methods, such as sliding connection, that is, pushing and pulling left and right through horizontal slide rail; or it can be a flip cover type, that is, hinged through hinge shaft. In other words, as long as it can protect the abutting component and facilitate the installation and maintenance of the abutting component, it is acceptable.

[0095] In an optional embodiment, two traction frames 1 are also included; the two traction frames 1 are respectively disposed on opposite sides of the friction cleaning assembly, and are used to support the electrode conveyor belt 3 that enters and exits between the friction cleaning assembly and the contact assembly; the traction frame 1 has a belt threading gap that matches the width of the electrode conveyor belt 3.

[0096] In this embodiment, two traction frames 1 are respectively set at the front and rear positions of the cleaning box 2, which can support and pull the electrode conveyor belt 3 entering the cleaning box 2, thereby ensuring the stability of the electrode conveyor belt 3 when it is cleaned by the friction cleaning component in the cleaning box 2.

[0097] Specifically, in this embodiment, a belt threading gap is provided on the traction frame 1, the gap width of which just allows the electrode conveyor belt 3 to pass freely but restricts lateral swing.

[0098] During installation, simply fix the traction frame 1 to the frame with bolts, ensuring that the gap is aligned with the width of the electrode conveyor belt 3.

[0099] Secondly, this utility model provides an electrode conveying device, such as... Figure 1 As shown, it includes a transfer mechanism, an electrode conveyor belt, and a cleaning mechanism for the electrode conveyor belt as described in any of the foregoing embodiments; the electrode conveyor belt is disposed on the transfer mechanism, and the transfer mechanism can drive the electrode conveyor belt to rotate cyclically; the cleaning mechanism is used to clean the electrode conveyor belt.

[0100] In this embodiment, the transfer mechanism (not shown in the figure) can drive the electrode conveyor belt 3 to rotate, such as Figure 1 As shown, the lower side of the electrode conveyor belt 3 moves to the right, and the upper side of the electrode conveyor belt 3 moves to the left, causing the electrode above to move to the left. When the electrode is removed at the left end and enters the next process, the upper surface of its electrode conveyor belt 3 rotates downward, becoming the lower surface, so that it can be cleaned by the cleaning mechanism, forming a reciprocating motion.

[0101] The beneficial effects of this utility model are:

[0102] By actively rotating and rubbing the friction cleaning component against the second side of the electrode conveyor belt 3, the adhering adhesive particles, ceramic particles and other impurities are physically removed, avoiding any impact on the subsequent conveying of the electrode sheets. This ensures the surface flatness of the electrode sheets and the voltage test yield of the stacked modules, thereby improving the battery yield. The abutment component is supported on the first side of the electrode conveyor belt 3, forming a double-sided clamping structure with the friction cleaning component. This prevents the electrode conveyor belt 3 from shifting or shaking during the cleaning process, ensuring cleaning uniformity and stable conveying.

[0103] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
