[0060] Further, the mechanical arm 132 drives the extension column 1341 to move towards the conveying device 16, the first motor drives the first grabbing assembly to rotate above the conveying device 16, the first grabbing assembly places the jig 171 on the conveying device 16, the conveying device 16 conveys the jig 171 to the set position, the mechanical arm 132 drives the extension column 1341 to move towards the paint dipping pool 142 and moves the mounting plate 1342 above the paint dipping pool 142, the first motor drives the extension column 1341 to rotate so that the second grabbing assembly is above the paint dipping pool 142, the second grabbing assembly places the grabbed transformer 17 in the paint dipping pool 142, the above steps are repeated, when the transformers 17 in the paint dipping pool 142 are placed to the set number, the mechanical arm 132 drives the extension column 1341 to move above the table 15, the first grabbing assembly grabs the cover of the table 15 and places it above the transformer 17, so that the cover covers the terminals on the transformer 17 to avoid paint entering the terminals during painting, when the grabbing mechanism 13 covers all the terminals of the transformers 17 with the cover, the third mounting frame 1441 moves on the fixing frame 141, before the third mounting frame 1441 moves, the paint loading box 1443 rotates away from below the paint dripping part 1442 to avoid the paint dripping part 1442 from falling into the paint loading box 1443 during painting, after the paint loading box 1443 rotates away from the paint dripping part 1442, the third mounting frame 1441 moves, when the paint dripping part 1442 passes the coil of the transformer 17, the paint dripping part 1442 drips paint to drip the paint on the coil of the transformer 17, when the coil of the transformer 17 in the paint dipping pool 142 is painted, the third mounting frame 1441 returns to the initial position and the paper loading box rotates to return below the paint dripping part 1442.

[0061] Further, the fourth cylinder 145 drives the sealing cover 143 to seal the paint dipping pool 142, when the paint dipping pool 142 is sealed, the air extraction assembly extracts the air in the paint dipping pool 142 to eliminate the bubbles in the paint on the transformer 17, when the air extraction assembly extracts to the set value, the air extraction assembly stops extracting air, at the same time, the fourth cylinder 145 drives the sealing cover 143 to open the paint dipping pool 142, at the same time, the mechanical arm 132 drives the extension column 1341 to move into the paint dipping pool 142, so that the first grabbing assembly can descend to grab the cover on the transformer 17, at the same time, when the cover is grabbed by the first grabbing assembly, the first motor drives the extension column 1341 to rotate, so that the second grabbing assembly can descend to grab the painted transformer 17, when the cover and the painted transformer 17 are grabbed, the mechanical arm 132 drives the extension column 1341 to move above the table 15, so that the first grabbing assembly places the cover on the table 15, the mechanical arm 132 drives the extension column 1341 to the airing platform 122 again, so that the second grabbing assembly places the painted transformer 17 on the placing frame 1221, through the above operation, the transformers 17 are placed on the placing frame 1221 until they are full.

[0062] Further, since the two varnish application mechanisms 14 are provided, the two varnish application mechanisms 14 can alternately apply varnish to the transformer 17. When the first varnish application mechanism 14 is full of the transformer 17 after varnish application, the gripping mechanism 13 can grip the transformer 17 from the jacking assembly 1133 and place it in the second varnish application mechanism 14. During the process of gripping the transformer 17 by the gripping mechanism 13 and placing it in the second varnish application mechanism 14, the transformer 17 placed on the rack 1221 has enough time to drip the excess varnish on the drying table 122. When the second varnish application mechanism 14 is full of the transformer 17, the second varnish application mechanism 14 is in the process of applying varnish and pumping air, and the gripping mechanism 13 grips the transformer 17 on the drying table 122 and places it in the second baking device 121, so that the second baking device 121 further dries the varnish of the transformer 17. After the gripping mechanism 13 grips the transformer 17 on the drying table 122, the gripping mechanism 13 grips the transformer 17 from the jacking assembly 1133 and places it in the first varnish application mechanism 14, to form a cycle. Through the above operation, the transformer 17 is dried, gripped, varnished, dried, and varnished again to form a complete process, so as to reduce manual operation, effectively speed up the processing efficiency, and improve the production capacity.
