[0002] With the continuous advancement of battery technology, especially the widespread application of lithium-ion batteries in electric vehicles and energy storage, the quality of tab welding and tab cleaning in battery manufacturing processes has gradually become a crucial aspect of improving battery performance and production efficiency. In the battery production process, the tabs are key components connecting the battery plates to the external circuitry; their structure and cleaning effectiveness directly impact the battery's lifespan and safety.

[0003] In battery manufacturing, to improve product quality and ensure the consistency of the electrode tab edges, thereby achieving consistent tab width, companies typically perform powder removal treatments on the tab edges. Currently, there are many methods available, but ultrasonic adsorption is commonly used.

[0004] However, these traditional cleaning methods often have problems such as complicated operation, serious waste of raw materials and environmental pollution. At the same time, the vibration of the battery plates during ultrasonic treatment leads to poor width consistency of the electrode tabs after cleaning. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0031] A cleaning unit for residual slurry at the edge of a battery electrode plate 4 includes a mounting frame 1, a cleaning mechanism 2, and a driver 3. The mounting frame 1 is used to mount the driver 3. The cleaning mechanism 2 is connected to the output end of the driver 3. The cleaning mechanism 2 is used to clean the electrode plate 40 of the battery electrode plate 4. The driver 3 is used to drive the cleaning mechanism 2 to move away from or towards the electrode plate 40.

[0032] The cleaning mechanism 2 is provided with an elastic cleaning end 21, which forms an interference fit with the tab position 40.

[0033] like Figure 1 and Figure 3 As shown, in a specific embodiment, the tab position 40 is a rectangular groove that runs through the length of the battery plate 4. In use, the driver 3 makes the elastic cleaning end 21 of the cleaning mechanism 2 contact the tab position 40 of the battery plate 4, and then the output power of the driver 3 is increased so that the elastic cleaning end 21 is inserted into the tab position 40, keeping the cleaning unit stationary, while the battery plate 4 moves along the length direction.

[0034] With this structure, the edges of the cleaned tab position 40 are neat and clean, and the width of the tab position 40 is highly consistent, which solves the problem of uneven width of the tab position 40 after cleaning, which leads to poor welding when welding the tabs.

[0035] Preferably, it further includes a driving force adjustment unit, which is used to adjust the driving force of the driver 3.

[0036] In a specific embodiment, the actuator 3 is a cylinder, and the driving force adjustment unit is a pneumatic pressure regulating valve. By adjusting the pressure of the cylinder, the pressure between the elastic cleaning end 21 and the tab is adjusted. Using this structure, the cleaning effect of residual slurry at the edge of the tab position 40 can be observed during operation. The cylinder pressure can be finely adjusted to ensure the cleanliness of the tab position 40 meets requirements, without damaging the battery plates 4. This solves the problems of insufficient pressure leading to incomplete cleaning of the tab position 40 and excessive pressure damaging the battery plates 4, which are caused by the inability to adjust the cleaning force.

[0037] Preferably, the cleaning mechanism 2 includes a connector 22 and a resin core 23. The connector 22 is connected to the output end of the driver 3. One end of the resin core 23 is detachably connected to the connector 22, and the other end of the resin core 23 is the elastic cleaning end 21.

[0038] The resin core 23 is wear-resistant and elastic. The resin core 23 is detachable. If the elastic cleaning end 21 wears during use, it can be easily disassembled, repaired, and replaced for reuse.

[0039] Preferably, the mounting bracket 1 includes a base plate 11, a needle-threading plate 12, a cover plate 13, a fixing member 14, and a mounting block 15;

[0040] The needle plate 12 is provided with a needle groove 121 through the driving direction of the driver 3. The connector 22 and the resin core 23 are inserted into the needle groove 121. The connector 22 and the resin core 23 can move within the needle groove 121 along the driving direction of the driver 3.

[0041] The needle plate 12 is disposed between the base plate 11 and the cover plate 13. The base plate 11, the needle plate 12 and the cover plate 13 are provided with matching fixing holes. The fixing member 14 is inserted into the fixing hole and is used to lock the base plate 11, the needle plate 12 and the cover plate 13.

[0042] The mounting block 15 is connected to the base plate. The mounting block 15 is provided with a mounting hole 151. The mounting hole 151 is coaxially arranged with the needle groove 121. The mounting hole 151 is used to install the driver 3.

[0043] like Figure 2 As shown, in a specific embodiment, the driver 3 is mounted on the mounting block 15, the output end of the driver 3 passes through the mounting hole 151, and the connector 22 and resin core 23 pass through the needle groove 121. The cleaning mechanism 2 is circumferentially limited and installed through the coaxially arranged mounting hole 151 and needle groove 121. Bolts are used as fasteners 14 to lock the base plate 11, needle plate 12 and cover plate 13, which solves the problem that the cleaning mechanism 2 is not installed stably and affects the cleaning effect of the tab position 40.

[0044] Preferably, the mounting bracket 1 is provided with a positioning bracket 16 and a positioning hole 17, and a positioning pin bushing 171 is provided in the positioning hole 17. The positioning bracket 16 and the positioning pin bushing 171 are used to fix the mounting bracket 1 to an external device.

[0045] In a specific embodiment, two circular positioning holes 17 are respectively provided at both ends of the base plate 11. An annular positioning pin bushing 171 is nested in the positioning hole 17. Two right-angled positioning frames 16 are provided at both ends of the base plate 11 facing each other. One straight side of the positioning frame 16 is connected to the base plate 11, and the other straight side is fixed to the external device. With this structure, the positioning holes 17 and the positioning frames 16 fix the cleaning unit simultaneously from two vertical directions.

[0046] Preferably, the mounting bracket 1 is provided with a protrusion 18, which surrounds the outer periphery of the elastic cleaning end 21 and is used to support the elastic cleaning end 21.

[0047] In a specific embodiment, to prevent the mounting bracket 1 from scratching and damaging the battery plate 4, a gap is left between the mounting bracket 1 and the battery plate 4. A protrusion 18 is used to support the elastic cleaning end 21, which solves the problem that the elastic cleaning end 21 extends too far out of the mounting bracket 1, resulting in insufficient support or breakage.

[0048] Each end of the mounting bracket 1 is provided with a handle 19, which is used for manual gripping during installation or disassembly.

[0049] In a specific embodiment, handles 19 are installed at both ends of the base plate 11. The addition of handles 19 facilitates manual disassembly and cleaning of the entire unit, and makes installation and maintenance easier.

[0050] Preferably, the material of the elastic cleaning end 21 is selected to have a hardness greater than that of the molded slurry.

[0051] In one embodiment, the elastic cleaning end 21 is made of resin core 23. The cleaning of the tab is to clean the coating formed by the slurry molding on the battery plate. The resin core is made of a material with a hardness greater than that of the slurry coating to avoid the problem of the elastic cleaning end 21 wearing out too quickly, which would lead to too frequent downtime for replacement.

[0052] Preferably, four sets of cleaning mechanisms 2 and four sets of drivers 3 are provided, with the four cleaning mechanisms 2 arranged in parallel and the four drivers 3 arranged in parallel.

[0053] In a specific embodiment, the battery plate 4 has four tab positions 40 on the same side. Four sets of cleaning mechanisms 2 and drivers 3 are used to clean the four tab positions 40 on the same side, thereby improving cleaning efficiency.

[0054] A device for cleaning residual slurry at the edge of a tab includes a fixed frame, a roller 5, and the aforementioned cleaning unit for residual slurry at the edge of a tab. The fixed frame is used to fix the cleaning unit, and the roller 5 is used to rotatably support the battery electrode 4 to be cleaned. The cleaning unit and the roller 5 are respectively disposed on both sides of the battery electrode 4 in the thickness direction, and the cleaning unit and the roller 5 are disposed opposite to each other.

[0055] In a specific embodiment, when the cleaning unit performs cleaning work, the elastic cleaning end 21 of the cleaning unit abuts against the roller 5. The elastic cleaning end 21 and the roller 5 clamp and support the battery plate 4 from both sides along the thickness direction of the battery plate 4 to ensure sufficient cleaning force while avoiding damage to the battery plate 4.

[0056] Preferably, two sets of rollers 5 and cleaning units are arranged opposite each other, with the two rollers 5 arranged in opposite directions and the two cleaning units arranged in opposite directions.

[0057] like Figure 3 In a specific embodiment, two rollers are provided, one facing forward and one facing backward, offset on both sides of the battery electrode plate in the thickness direction to facilitate flattening and supporting the battery electrode plate. Two cleaning units are provided on both sides of the battery electrode plate in the thickness direction, facing forward and backward, opposite to the rollers. With this structure, the tab positions 40 on both sides of the battery electrode plate 4 can be cleaned simultaneously, improving cleaning efficiency.

[0058] Other configurations and operations according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
