Description

Technical Field

[0001] This utility model relates to the field of battery production equipment, specifically a cylindrical battery electrode roll cleaning device. Background Technology

[0002] In the current new energy industry, coated electrodes need to be compacted by a roller press to ensure that the active materials are tightly arranged, reduce the electrode thickness, improve conductivity, and extend cycle life. However, the negative electrode is water-based and is prone to powdering after drying, especially during the roller pressing process. After a period of time, the rollers will be covered with powder. The industry commonly uses scrapers and non-woven fabrics with chemical solvents to clean the rollers through contact. However, if the scraper is too tight, it will scratch the rollers, and if it is too loose, it will not clean properly. The non-woven fabrics with chemical solvents will leave solvent residue. Moreover, both of these methods have high daily wear and tear and are costly. The utility model with application number 202421453091.X provides a battery roller wiping and cleaning mechanism, including a wiping device, a detection device, and a control system. The wiping device is disposed above the roller and includes a dust removal hood and a spraying assembly. The dust removal hood covers the roller surface and can wipe the stains on the roller surface. The spraying assembly can spray dry ice from the dust removal hood toward the roller surface at one or more points to freeze and embrittle the stains. The detection device is placed parallel to the roller and is used to detect stains. The detection device is communicatively connected to the control system, and the control system can drive the wiping device to wipe the stains at one or more points.

[0003] The present invention has the following technical problems: 1. The stains after dry ice spraying are scattered everywhere and cannot be collected into the container smoothly; 2. After the dry ice melts, it turns into gaseous carbon dioxide, which accumulates in large quantities in the workshop and poses a safety hazard. Utility Model Content

[0004] This utility model provides a cylindrical battery electrode roll cleaning device to solve one of the above-mentioned technical problems.

[0005] A cylindrical battery electrode roll cleaning device includes a spraying assembly and a collecting assembly. The spraying assembly includes a spray gun that is directed at the roll. The collecting assembly includes a negative pressure pipe and a collecting hood. The negative pressure pipe is connected to the collecting hood, which is located outside the roll. The nozzle of the spray gun is located inside the collecting hood.

[0006] Furthermore, the negative pressure pipe has a horizontal pipe and a vertical pipe, the horizontal pipe is connected to the vertical pipe, the vertical pipe has a filter screen inside, and the bottom of the vertical pipe has a collection box, which is threadedly connected to the vertical pipe.

[0007] Furthermore, the spray gun is flat, and a buffer block is provided inside the spray gun. Lead screws are connected to both sides of the spray gun, and the other end of the lead screws is connected to a motor.

[0008] Furthermore, the spraying assembly also includes a motor, a lead screw, a slider, and a limiting rod. The output end of the motor is connected to the lead screw, the lead screw is slidably connected to the slider, the slider is movably connected to the limiting rod, and the spray gun is fixedly connected to the slider.

[0009] Furthermore, the cylindrical battery electrode roll cleaning device also includes a camera facing the roll.

[0010] Furthermore, the negative pressure pipe is connected to the vacuum pump.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: the stains that have been detached by dry ice spray in the collection hood are extracted together with carbon dioxide through the negative pressure pipe, preventing the stains from falling back onto the rollers and preventing carbon dioxide from accumulating in the production workshop; the stains are collected into the collection box through the filter screen installed in the vertical pipe, and the collection box is detachable for easy cleaning; the condition of the rollers is observed through the camera, and the position of the spray gun is adjusted by the motor to accurately clean areas with more stains.

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

The collecting hood 4 is located outside the roll 2, and the nozzle of the spray gun 1 is located inside the collecting hood 4. The negative pressure pipe 3 can draw away carbon dioxide and dirt from the collecting hood 4 together, preventing carbon dioxide accumulation and secondary pollution of dirt. The spray gun 1 is flat and has a buffer block 9 inside. The buffer block 9 can better disperse the dry ice particles. Screws 10 are connected to both sides of the spray gun 1. The other end of the screws 10 is connected to a motor 11. The motor 11 drives the screws 10 to rotate, thereby adjusting the spraying angle of the spray gun 1.
