Description

Technical Field

[0001] The utility model belongs to the technical field of battery pole piece production equipment, and particularly relates to a cleaning baffle structure and a roller surface cleaning mechanism. Background Art

[0002] The electrode refers to the key part of the battery used to store and release electrical energy. The production process of battery electrodes usually includes slurry preparation, coating, rolling and slitting. The slurry is prepared by evenly mixing the active material, conductive agent and adhesive. The slurry is evenly coated on the metal foil to form the precursor of the electrode. The coated electrode is then compacted by a roller press to increase the density and strength of the electrode. Finally, the rolled electrode is cut according to the required size to obtain the electrode product.

[0003] During the electrode rolling process, a roller press is typically used. The roller press primarily includes rollers for squeezing the electrode. During rolling, residual electrode powder easily adheres to the roller surface, potentially affecting subsequent rolling. To ensure the roller's cleanliness, a roller surface cleaning mechanism is required to wipe and clean the roller surface. Existing roller surface cleaning mechanisms typically include a nozzle for spraying a cleaning solvent onto the roller surface. The nozzle is connected to a drive member that drives the nozzle to move so that the cleaning solvent sprays across the entire roller surface.

[0004] However, the electrode to be rolled includes the tab area. When the cleaning solvent on the roller surface is not dried in time, the roller will easily adhere the undried cleaning solvent to the tab area when rolling the electrode, thereby affecting the production and manufacturing of the back end of the battery. For example, the tab may become desoldered or have a cold weld during the welding process. Utility Model Content

[0005] In order to solve the shortcomings of the existing technology, the utility model provides a cleaning baffle structure and a roller surface cleaning mechanism. The baffle assembly and the baffle cloth block the cleaning solvent sprayed by the nozzle, and a dry area without cleaning solvent is formed on the surface of the roller. The dry area corresponds to the tab area to solve the problem that the cleaning solvent is not dry, resulting in the cleaning solvent easily adhering to the tab area when the roller presses the tab area, thereby affecting the electromagnetic back-end process.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical aspects:

[0007] In a first aspect, the present utility model provides a cleaning baffle structure, which includes a baffle assembly corresponding to the tab area, including an intermediate baffle and an adjustment baffle. The adjustment baffle is stacked on one side of the intermediate baffle and is detachably connected to the intermediate baffle to adjust the overlapping area between the adjustment baffle and the intermediate baffle. The baffle assembly is adapted to the width of the tab; a baffle cloth is provided on the adjustment baffle for blocking the sprayed cleaning solvent; and a collection box is provided on one side of the baffle assembly for collecting the dripping cleaning solvent.

[0008] In some implementation manners, a waist-shaped hole is formed in the adjustment baffle, and a locking member is provided between the adjustment baffle and the intermediate baffle at the waist-shaped hole.

[0009] In some implementation manners, the adjustment baffle includes a first sheet body and a second sheet body, and the first sheet body and the second sheet body are respectively located on both sides of the intermediate baffle.

[0010] In some implementation manners, the first sheet body includes a plurality of first fitting portions, and a plurality of first fitting openings are formed in the first sheet body. The plurality of first fitting openings and the plurality of first fitting portions are alternately arranged;

[0011] The second sheet body includes a plurality of second fitting portions adapted to the first fitting openings, and a plurality of second fitting openings adapted to the first fitting portions are formed in the second sheet body. The plurality of second fitting openings and the plurality of second fitting portions are alternately arranged, and the first sheet body and the second sheet body are mutually fitted.

[0012] In some implementation manners, a plurality of locking holes are formed in the intermediate baffle, and the intermediate baffle is detachably connected to the first sheet body and the second sheet body respectively at the locking holes.

[0013] In some implementation manners, a bent portion for fixing the baffle cloth is formed on the adjustment baffle.

[0014] In some implementation manners, a connecting piece is provided on one side of the intermediate baffle, the collection box is located on the connecting piece, a third waist-shaped hole is formed in the connecting piece along the width direction of the tab, and the intermediate baffle is detachably connected to the connecting piece at the third waist-shaped hole.

[0015] In some implementation manners, a diversion joint for discharging the cleaning solvent is provided on the collection box, and the diversion joint is communicated with the collection box.

[0016] In a second aspect, the present utility model provides a roller surface cleaning mechanism, which includes the above-mentioned cleaning baffle structure. A spray head for spraying the cleaning solvent is provided on one side of the baffle assembly, and the spray head is drivingly connected to a driving assembly for driving the spray head to move.

[0017] In some implementations, a plurality of the cleaning flap structures are provided, and the plurality of the cleaning structures are spaced apart along the moving direction of the nozzle.

[0018] In summary, the present utility model has at least the following advantages:

[0019] 1. For the cleaning flap structure provided by the present utility model, before cleaning the roller surface, after adjusting the overlapping area of the adjusting flap and the intermediate flap, the adjusting flap is connected to the intermediate flap, and the flap assembly can adapt to the width of the tab. When spraying the cleaning solvent, the flap assembly blocks and absorbs the sprayed cleaning solvent, and a dry area where the cleaning solvent is not sprayed is formed correspondingly on the surface of the roller. Since the flap assembly is correspondingly arranged with the tab area, the dry area can correspond to the tab area, and the cleaning solvent is only sprayed on other areas of the roller surface except the dry area. While ensuring the cleaning effect of the roller, it can solve the problem that the cleaning solvent is not dried in time, and after the roller rolls the electrode sheet, the undried cleaning solvent adheres to the tab area, thereby affecting the subsequent production of the battery.

[0020] The collection box collects the cleaning solvent blocked by the flap assembly to centrally process the cleaning solvent, and reduces the influence of the dripping cleaning solvent on the processing effect of the electrode sheet.

[0021] 2. For the roller surface cleaning mechanism provided by the present utility model, the driving assembly drives the nozzle to move, and the nozzle sprays the cleaning solvent while moving. When the nozzle moves to the cleaning flap structure, the flap assembly blocks on one side of the nozzle, so that a dry area where the cleaning solvent is not sprayed is formed on the surface of the roller, thereby realizing the zonal cleaning of the roller. The nozzle and the driving assembly do not need to stop operating, which is beneficial to improving the cleaning efficiency of the roller surface and ensuring the quality of the electrode sheet product.

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are some but not all of the embodiments of the present utility model.

[0037] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0038] Example 1:

[0039] Please refer to the appendix Figures 1-3 , the cleaning flap structure of the present utility model includes a flap assembly 1, a cloth baffle 2 is arranged on the flap assembly 1, and a collection box 3 is arranged on one side of the flap assembly 1, which can be used in the roller surface cleaning mechanism of the battery electrode plate 7 roller press to achieve regional cleaning of the surface of the roller 6.

[0040] Among them, with reference to Figure 1, the baffle assembly 1 includes an intermediate baffle 11 which is specifically arranged vertically. An adjusting baffle 12 is arranged on one side of the intermediate baffle 11. The adjusting baffle 12 is stacked on one side of the intermediate baffle 11 and is detachably connected to the intermediate baffle 11. By adjusting the overlapping area between the adjusting baffle 12 and the intermediate baffle 11, the overall width of the baffle assembly 1 is adjusted. The width of the baffle assembly 1 is adapted to the width of the tab. At the same time, the baffle assembly 1 is correspondingly arranged with the tab area 71.

[0041] Refer to Figure 2 , a baffle cloth 2 is arranged on the adjusting baffle 12. Specifically, the baffle cloth 2 is preferably but not limited to non-woven fabric. The baffle cloth 2 can be attached to the adjusting baffle 12 to block and absorb the sprayed cleaning solvent. The baffle cloth 2 can cover the gap between the adjusting baffle 12 and the intermediate baffle 11, improving the effect of the baffle assembly 1 in blocking the cleaning solvent.

[0042] Refer to Figure 1 , a collecting box 3 for collecting the dripping cleaning solvent is arranged on one side of the intermediate baffle 11. In some specific embodiments shown, the collecting box 3 is located at the bottom of the baffle assembly 1. The cleaning solvent blocked by the baffle assembly 1 drips into the collecting box 3, realizing unified collection of the cleaning solvent and reducing the problem of the dripping cleaning solvent polluting other areas. In a preferred embodiment, a diversion joint 31 is communicated with the collecting box 3. Specifically, the diversion joint 31 is located at the bottom of the collecting box 3. The cleaning solvent accumulated at the collecting box 3 can flow out through the diversion joint 31, eliminating the need for manual dumping of the collecting box 3 and improving the convenience of use.

[0043] Refer to Figures 1-3 , before the surface of the roller 6 is wiped and cleaned, the adjusting baffle 12 is detachably connected to the intermediate baffle 11, the overlapping area between the adjusting baffle 12 and the intermediate baffle 11 is reasonable, and the width of the baffle assembly 1 is adapted to the width of the tab. The cleaning solvent is sprayed onto the roller surface of the roller 6. The baffle assembly 1 can block the cleaning solvent from being sprayed onto the roller surface of the roller 6. The roller surface of the roller 6 flows out of the drying area 61, and the drying area 61 corresponds to the tab area 71 and has the same width. When the roller 6 rolls the electrode sheet 7 again, the drying area 61 where no cleaning solvent is sprayed can remain dry. The formation of the drying area 61 on the roller 6 can reduce the possibility that the cleaning solvent on the roller surface is not dried in time, resulting in the adhesion of the undried cleaning solvent to the tab area 71 during the rolling of the roller 6, thereby affecting subsequent processes such as tab welding. The structure of the baffle assembly 1 is simple and easy to operate.
