[0002] At present, most of the coated products need to be coated with coating equipment. During the coating process, the nozzle continuously sprays and scatters ionic substances. The amount of spraying and the adhesion are greatly affected by the magnetic field. If the magnetic field strength in the cavity of the coating equipment is different, the thickness of the coating film layer will be different, resulting in low product quality and high product defect rate, which increases the production cost of the enterprise and brings inconvenience to the coating. Therefore, most of the coating equipment currently uses a magnetic field adjustment machine to adjust its internal magnetic field during the coating operation. The magnetic field adjustment machine is installed on the coating equipment to make the magnetic field in the cavity of the coating equipment uniform, thereby ensuring the coating effect of the product. However, the magnetic field strength of the magnetic field adjustment machine commonly used at present is mostly fixed, and the magnetic field size cannot be changed. During the coating process, if the magnetic field needs to be adjusted according to the magnetic field requirements of the workpiece, it is necessary to manually replace the magnet or similar magnets in the magnetic field adjustment machine. Related magnetic field mounting parts to adjust the magnetic field strength, this method is not only difficult to operate and cumbersome, but also cannot be adjusted continuously, which brings inconvenience to the coating operation.
