After the varnishing is completed, the varnish in the varnishing box is introduced into the filter box by starting the solenoid valve to open the connecting pipe. At this time, the varnish is filtered through the filter plate to prevent impurities from entering the varnish storage tank. When the varnish in the varnishing box is completely lost, the heating lamp is turned on to accelerate the temperature inside the varnishing box, and the fan is driven to rotate by starting the driving motor on the top of the box door. The fan and the heating lamp form a Hot air improves the drying efficiency of the dry-type transformer. After the vehicle is dried, the lifting motor can be started to drive the placement plate and the dry-type transformer to slide upward, so that the dry-type transformer can be lifted and taken out by the lifting device. The derived paint liquid is filtered by providing a filtering component to avoid impurities from mixing into the paint liquid during the dry-type transformer immersion process, thereby affecting the subsequent immersion quality. The drying component can accelerate the drying of the dry-type transformer after the immersion in the immersion box is completed, thereby improving work efficiency. At the same time, it is avoided that the paint liquid drips to the outside when it is taken out and needs to be cleaned up later. BRIEF DESCRIPTION OF THE DRAWINGS
