On the whole, the substrate protection layer coating system provided by the embodiment of the application realizes the automatic production of the surface anti-rust oil spraying of the thin-wall drill substrate, and workers can complete all production contents only by assembling and disassembling the thin-wall drill substrate. In addition, the coating system adopts a spraying treatment mode, compared with a soaking treatment mode, an oil film formed by spraying treatment is more uniform, the thickness can be controlled, and the dripping phenomenon can not be generated, so that the coating system does not need to stand, and the subsequent treatment process can be carried out after the spraying is finished.

Compared with the original production process, the treatment time is shortened, the production efficiency is improved, and the utilization rate of the anti-rust oil is higher.

Referring to fig. 6 and 7, as an embodiment of the application for providing a substrate protective layer coating system, the hook 1 comprises a hook body 161, a channel 162, a piston 163, a screw 164, a swing rod 165, a magnet 166, and the like, wherein the channel 162 is located in the hook body 161, and the piston 163 is located in the channel 162 and can slide back and forth in the channel 162.

The screw 164 is screwed on the hook 161, and one end of the screw 164 extends into the channel 162 after passing through the hook 161 and is connected to the piston 163, and the screw 164 is connected to the piston 163 in a rotating manner, so that the screw 164 can pull the piston 163 to slide in the channel 162 in a reciprocating manner during rotation.
