[0002] Metal parts coating is a process of covering the surface of metal parts with a thin film, which is usually used to improve the corrosion resistance, wear resistance, decorativeness and electrical performance of metal parts. Coating technology is widely used in various industries, such as aviation, electronics, automobiles, machinery, medical, etc. Metal parts coating is an important means to improve the performance of metals. It can not only improve the physical and chemical properties of metals, but also provide beautiful surface effects. Different coating technologies have their own advantages and application scenarios. Choosing a suitable coating method is of great significance to improving product quality and extending service life.

Then the main motor 103 rotates to drive the input shaft 106 to rotate, thereby driving the docking shaft 107 and the turntable 110 to rotate, thereby driving the outer sleeve 121 to move, and the compression spring 111 is always in a compressed state. During the rotation of the turntable 110, the sliding block 119 always slides along the circular arc segment groove 136 and the convex groove 137. When the sliding block 119 and the outer sleeve 121 move to the lower pressure block 127, the sliding block 119 and the outer sleeve 121 slide outward along the sliding groove 135 and the convex groove 137 under the action of the compression spring 111, and the lower pressure block 127 and the lower pressure rack 129 are pushed downward by the sliding block 119, and the lower pressure spring 128 is compressed, and the lower pressure rack 129 drives the intermediate gear 130 to rotate, and the intermediate gear 130 drives the upper rack 131 and the slide plate 133 to rise, thereby driving the coating pool 134 to rise, so that the coating part 126 enters the coating pool 134, and at this time under the action of the compression spring 111, the inner rotating gear 120 is meshed with the inner gear ring 116, and the rotating motor 112 rotates to drive the motor gear 113 to rotate, thereby driving the outer gear 115, the rotating ring 114 and the inner gear ring 116 to rotate, thereby driving the inner rotating gear 120, the inner rotating cylinder 122, the outer sliding sleeve 121 and the inner support sheet 123 to rotate together, thereby driving the coating part 126 to rotate, and realizing a full circle of coating of the coating part 126.When the outer sleeve 121 with the uncoated coated part 126 moves to the lower pressing block 127, the coated part 126 that has been coated follows the cone head 125 and the outer sleeve 121 to move in front of the clamping plate 312, and the moving-out electric cylinder 304 contracts, so that the circular groove of the discharge shell 302 reaches the outside of the coated part 126, and then the clamping electric cylinder 306 extends, driving the clamping frame 307 to move toward the coated part 126, and the clamping frame 307 drives the pulling plate 310 to move, thereby driving the clamping plate 312 to rotate through the slide block 311, so that the coated part 126 is clamped by the three clamping plates 312, and then the loosening electric cylinder 1 17 extends, driving the release head 118 to extend, and the release head 118 drives the two inner support sheets 123 to move inward, and the inner support spring 124 is compressed, so that the cone head 125 no longer blocks the coated part 126, and the inner support sheet 123 no longer tensions the coated part 126, and then the moving-out electric cylinder 304 extends, and the coated part 126 leaves the cone head 125 through the clamping plate 312 and the discharge shell 302, and then the clamping electric cylinder 306 contracts, driving the pull-out plate 310 to slide, thereby driving the clamping plate 312 to rotate and open, so that the clamping plate 312 no longer clamps the coated part 126, and the coated part 126 slides out along the space inside the discharge shell 302.
