In this embodiment, the brush rollers are not indicated by reference numerals. The brush rollers can be driven to rotate by the brush drive, thereby removing dust from the surface of the electrode roll. The brush drive can be a motor or other driving component. The ultrasonic dust removal unit 11 achieves non-contact dust removal of the electrode roll through physical vibration, avoiding the risk of scratches that may be caused by traditional cleaning methods.

[0035] Working principle of the invention: In this embodiment, by Figure 1It is known that the unwinding mechanism 1 winds the battery electrode roll and outputs the battery electrode roll. First, it passes through the unwinding correction mechanism 20 to realize the alignment of the battery electrode roll (hereinafter referred to as the electrode roll). After the alignment, the electrode roll can be connected to the previous electrode roll through the unwinding splicing mechanism 21, so that one end of the electrode roll output by the unwinding mechanism 1 is connected to one end of the previous electrode roll, thus completing the connection of the electrode roll. After the connection, the electrode roll is tensioned by the unwinding tension swing arm mechanism 22. After the tension adjustment, the electrode roll is buffered by the unwinding buffer mechanism 23 to ensure that the electrode roll to be cleaned is provided to the first cleaning mechanism 4 without intermittent output. In this embodiment, the first cleaning mechanism 4 and the second cleaning mechanism 8 have the same structure, but the electrode roll after the front cleaning of the first cleaning mechanism is buffered by the first buffer mechanism 5 and the front cleaning of the electrode roll is adjusted by several first buffer rollers 51, so as to be transported to the second cleaning mechanism 8 for back cleaning. In this embodiment, the cleaning is performed on the grooves of the electrode roll. A laser beam is output from the first laser head 43 to clean the grooves on the front side of the electrode roll, and a laser beam is output from the second laser head 83 to clean the grooves on the back side. In this embodiment, the laser excitation source, working medium, and resonant cavity are emitted from the output port of the first or second laser to perform high-temperature melting, combustion, and vaporization of the active material on both sides of the coating area of ​​the battery electrode roll. Simultaneously, auxiliary ventilation and dust removal are provided to achieve the purpose of exposing the metal conductive current collector of the bare electrode roll, making it suitable for battery tab welding. Auxiliary ventilation and dust removal structures can be installed on one side of the first adsorption structure 45 and one side of the second adsorption structure 85. This equipment, by adopting a continuous conveyor belt method, allows for simultaneous laser groove cleaning and electrode roll conveying, solving the problem of poor traditional cleaning effects and greatly improving equipment efficiency. Specifically, as... Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the first annular guide rail 44 can be composed of two first linear units and two first arc-shaped units to form a closed annular guide rail. Similarly, the second annular guide rail 84 is composed of two first linear units and two first arc-shaped units to form a closed annular guide rail. The first pallet 13 can slide cyclically along the first annular guide rail 44, and can sequentially adsorb and transport the passing electrode roll material. The first pallet 13 can slide clockwise on the first annular guide rail 44, and the second pallet 15 can slide clockwise on the second annular guide rail 84. The first pallet 13 is provided with multiple first adsorption holes. The negative pressure unit 14 can be selected as a negative pressure micro fan. Each negative pressure unit 14 can correspond to a negative pressure micro fan. The negative pressure micro fan can adsorb the electrode roll material on the first pallet 13 through the corresponding first adsorption holes. At the same time, a stator is embedded on the first annular guide rail 44, and a mover is provided on each first pallet 13. The stator and the mover can be magnetically connected to achieve magnetic drive. In another embodiment, a chain plate line 27 is provided on the first annular guide rail 44. The chain plate line 27 is driven by a motor, and multiple first pallets 13 move with the movement of the chain plate line 27. Similarly, the second cleaning mechanism 8 has the same structure and cleaning principle as the first cleaning mechanism 4, so it will not be described again. After the groove of the electrode roll is cleaned on the front and back sides, it is dusted by the dust removal component. In this embodiment, brush dust removal and ultrasonic dust removal are included. The electrode roll is cleaned on both sides by two dust removal methods, and is not limited to the above two dust removal methods. After dust removal, the electrode roll also needs to be inspected by the detection component, including the length dimension detection and thickness detection of the electrode roll. Finally, it is wound up to complete the groove cleaning process. Both the first traction mechanism 3 and the second traction mechanism 7 can traction the electrode roll to provide traction force for the conveying of the electrode roll. In this embodiment, multiple first buffer rollers 51 are selected, and the number of first buffer rollers 51 can be selected according to the specific settings. In this embodiment, the laser beam output from the first laser head 43 can clean the front slots of the electrode roll multiple times during the transfer process (two, three, or more times, depending on the specific situation). The laser beam output from the second laser head 83 can also clean the front slots of the electrode roll multiple times during the transfer process. The front and back sides of the electrode roll are determined according to the actual situation. In this embodiment, the laser beam cleaning of the electrode roll during the transfer process is a flying cleaning mode, that is, the cleaning of the electrode roll slots and the conveying of the electrode roll are carried out simultaneously. The number of the first laser head 43 and the second laser head 83 can be selected as one, two, or three, and the number of the first laser head 43 and the second laser head 83 can be set according to actual needs. In another embodiment, the first adsorption structure 45 and the second adsorption structure 85 include a second support plate 15 and a first negative pressure cavity 16, such as... Figure 3As shown, the top of the first negative pressure chamber 16 has an opening that connects to the second adsorption hole that runs vertically through the second support plate 15. The bottom of the first negative pressure chamber 16 can be connected to a negative pressure source, such as an air pump. The electrode roll on the second support plate 15 can be adsorbed by negative pressure through the first negative pressure chamber 16 and the second adsorption hole, achieving the effect of adsorbing and transferring the electrode roll. The continuous conveyor belt method is a continuous conveying and cleaning processing method.
