[0016] Preferably, a spraying method for a spraying device for corrosion-resistant processing of automotive precision parts includes the following steps:

[0017] Step 1: Install a fixture for fixing automotive precision parts on the mounting plate, so that the automotive precision parts are fixed above the vertical rod through the fixture. Subsequently, adjust the height of the L-shaped frame according to the size of the automotive precision parts. Drive the second cylinder to adjust the height of the L-shaped frame. At the same time, control the electric push rod to drive the cross frame to move according to the requirements and the size of the precision parts, ensuring that the precision parts can accurately move to the inner center of the L-shaped frame during transmission. And drive the moving plate to translate through the screw to adjust the position of the L-shaped frame;

[0018] Step 2: Convey several precision parts to the inside of the spraying box in sequence through the conveyor belt. When the precision parts move to the upper end inside the L-shaped frame, control the first cylinder to drive the lifting plate to rise, closing both sides of the L-shaped frame to prevent paint mist from drifting to the precision parts on both sides during spraying;

The conveyor belt drives the precision parts to move backward. At the same time, the unsprayed precision parts in the front move above the L-shaped frame for spraying. Repeating the above steps can realize the automatic spraying treatment of precision parts, and at the same time ensure the treatment of paint mist and waste gas.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

In the present invention, by installing an L-shaped frame inside the spraying box, the L-shaped frame is composed of a bottom plate and side plates, and fans are arranged on the surfaces of the side plates and the bottom plate, which can uniformly collect and treat the paint mist and waste gas generated during spraying, ensuring the environment inside the device, and at the same time reducing the occurrence of the situation where the paint mist and waste gas affect the inside of the device. At the same time, liftable and movable lifting plates are arranged on both sides of the L-shaped frame. The lifting plates rise when the precision parts move to the inside of the L-shaped frame, which can reduce the occurrence of paint mist drifting to the precision parts on both sides, centrally treat the paint mist, and at the same time the liftable lifting plates will not affect the transmission of the precision parts.

[0023] 2. By installing the transmission system on the inner side of the spraying box, the transmission system consists of a conveyor belt and a driving roller. Several cross frames and vertical rods are installed on the surface of the conveyor belt. An installation plate is arranged above the vertical rod.

The precision part can be installed above the vertical rod, so as to realize the automatic transmission of the precision part. At the same time, the transmission system is arranged on one side, and this position and structure will not affect the internal structure, and can also smoothly convey the precision part into the L-shaped frame.

[0024] 3. The L-shaped frame is driven to move horizontally by the moving plate and can be adjusted according to the position of the precision part. A cylinder is installed above the precision part, and the cylinder can adjust the height of the L-shaped frame, so that it can be adjusted according to the position and size of the precision part, ensuring that the precision part is always at the center inside the L-shaped frame. At the same time, a cylinder is also arranged at the bottom of the lifting plate, and the up and down movement of the lifting plate is realized by the drive of the cylinder, so as to avoid the movement of the precision part.

[0039] Please refer to Figures 1-5 , a spraying method for a spraying device for anti-corrosion processing of automotive precision parts, including the following steps:

[0040] Step 1: Install a fixture for fixing automotive precision parts on the installation plate 9, so that the automotive precision parts are fixed above the vertical rod 8 through the fixture. Subsequently, adjust the height of the L-shaped frame 24 according to the size of the automotive precision parts. Adjust the height of the L-shaped frame 24 by driving the second air cylinder 22. At the same time, control the electric push rod 6 to drive the cross frame 7 to move according to the requirements and the size of the precision parts, ensuring that the precision parts can accurately move to the center inside the L-shaped frame 24 during transmission, and drive the moving plate 13 to translate through the screw rod 14 to adjust the position of the L-shaped frame 24;
