Foil coating treatment device suitable for battery pole piece production

The invention discloses a foil coating treatment device suitable for battery pole piece production, which is used for treating coiled foil in a conveying process, and comprises a first ultrasonic mechanism, the first ultrasonic mechanism comprises a first ultrasonic mold, the first ultrasonic mold is sequentially connected with a first amplitude-change pole and a first transducer, and the first amplitude-change pole is connected with a second ultrasonic mold. The first transducer is electrically connected with the ultrasonic generator; one face of the foil is coated with slurry, the first ultrasonic mold abuts against the other face of the foil and is in tensioning fit with the foil, and the width of the ultrasonic vibration working range of the first ultrasonic mold is larger than that of the foil; and the first ultrasonic mechanism acts on the foil which is coated but not dried. According to the treatment device, the uniformity and stability of slurry coating are improved through ultrasonic vibration energy
