The clamping mechanism 100 can clamp and fix the workpiece 600, the rotating mechanism 200 can drive the first clamp 130, the clamping driving assembly 140 and the workpiece 600 clamped between the first clamp 130 and the second clamp 150 to rotate, the unreeling mechanism 300 can continuously unreel the insulating film, the end part of the insulating film is adhered to the surface of the workpiece 600, and the workpiece 600 can rotate when the rotating mechanism 200 works, so that the insulating film can be wound on the surface of the workpiece 600, and coating is realized. The coating device of the embodiment can assist workers to work without winding the insulating film on the workpiece 600 by the workers, so that the labor intensity of the workers is reduced; and the tensioning degree of the insulating film wound on the workpiece 600 can be kept consistent, so that the quality of the coating is improved, and the quality of the coating is unified; and meanwhile, the coating efficiency is improved.

Specifically, in using the coating apparatus of the present embodiment, the workpiece 600 is manually held by hand, the workpiece 600 is placed on the side of the first clamp 130 near the clamp driving assembly 140, the second clamp 150 is moved toward the first support frame 110 by the clamp driving assembly 140 to narrow the distance from the first clamp 130 until the distance between the second clamp 150 and the first clamp 130 is equal to the length of the workpiece 600, at which time the workpiece 600 is clamped between the first clamp 130 and the second clamp 150, and the workpiece 600 can be rotated following the clamp driving assembly 140 and the first clamp 130.

And when the handle 162 stops swinging, the position of the slide bar 164 is fixed, i.e. the position of the slide bar 164 does not change under the condition of no external force; thus, on one hand, the distance between the second clamp 150 and the first clamp 130 can be conveniently adjusted, and on the other hand, the second clamp 150 can be positioned to prevent the workpiece 600 from being separated from the first clamp 130 and the second clamp 150 in the rotating process.
