Coating device and coating method thereof

The invention belongs to the field of target material processing, and discloses a coating device which comprises a mounting plate, an ultrasonic coating probe and a pressure sensor, the ultrasonic coating probe is movably connected to the mounting plate, and the pressure sensor is fixedly connected to the mounting plate. And the pressure sensor is used for detecting the pressure between the ultrasonic coating probe and the target material. The pressure sensor is arranged to control the pressure between the ultrasonic coating probe and the target material, so that the situation that the ultrasonic coating probe exerts too large pressure on the target material, high-frequency impact on the target material influences the finished product quality of the target material is avoided; and the situation that the distance between the ultrasonic coating probe and the target material is too long, and consequently brazing filler metal is distributed unevenly is avoided. 本发明属于靶材加工领域，公开了一种涂布装置，包括安装板、超声波涂布探头和压力传感器，所述超声波涂布探头活
