[0030] The numerical control box 8 is installed on one side of the frame 1 and is electrically connected to the belt conveyor 2, the electric hydraulic rod 4, the spraying mechanism 6 and the drying assembly 7.

[0031] Among them, locking screws 31 are threadedly installed at both ends of the sheet metal slot 301, and the spacing between the spraying slot 501 and the drying slot 502 is equal to the spacing between two adjacent clamping seats 3.

[0032] It should be noted that: when in use, the CNC box 8 is used to control the belt conveyor 2 to move at a fixed distance, so that the chassis sheet metal is inserted into the sheet metal slot 301 opened in the clamping seat 3, and then it is locked in the sheet metal slot 301 by screwing the locking screw 31, and then it is moved to the drying and spraying rack 5 in turn. When it moves to just above the spraying tank 501, the electric hydraulic rod 4 is started to drive the drying and spraying rack 5 to move, and then the spraying mechanism 6 is started to automatically spray paint on the chassis sheet metal from bottom to top, and after spraying, it continues to move to the drying tank 502. While spraying paint, the drying component 7 is started to dry the chassis sheet metal after spraying, so as to realize the integration of painting and drying, which is automatic, with a simple overall structure and high painting processing efficiency.

[0033] It should also be noted that the sheet metal slot 301 here is adapted to one end of the chassis sheet metal, so as to facilitate the insertion of the card into the chassis sheet metal.

[0034] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The spraying mechanism 6 includes a nozzle 61, and a plurality of nozzles 61 are provided, and the plurality of nozzles 61 are embedded around the spraying tank 501, and the plurality of nozzles 61 are commonly connected with a transfer tube 62, the transfer tube 62 is connected with a delivery pump 63 through a conduit, the delivery pump 63 is connected with a paint box 64 through a conduit, the paint box 64 is installed on the frame 1, the delivery pump 63 is installed on the upper surface of the paint box 64, and the delivery pump 63 is electrically connected with the numerical control box 8;

[0035] It should be noted that: when the spraying mechanism 6 is in the painting process, the paint in the paint box 64 is transported from the transfer tube 62 to the nozzle 61 embedded around the spray tank 501 through the delivery pump 63, and then the paint is sprayed on the chassis sheet metal in the spray tank 501 through the nozzle 61. During the painting process, excess paint automatically drips into the return funnel 65 and flows back into the paint box 64, thereby realizing paint recovery and avoiding paint waste.

[0036] In this embodiment, a liquid return funnel 65 is embedded on the paint box 64 just below the spray tank 501 .

[0041] When in use, the numerical control box 8 controls the belt conveyor 2 to move at a fixed distance, so that the chassis sheet metal is inserted into the sheet metal slot 301 opened by the clamping seat 3, and then locked in the sheet metal slot 301 by screwing the locking screw 31, and then moved to the drying and spraying rack 5 in turn. When it moves to the top of the spray tank 501, the electric hydraulic rod 4 is started to drive the drying and spraying rack 5 to move, and the paint in the paint box 64 is transported from the transfer tube 62 to the nozzle 61 embedded around the spray tank 501 through the delivery pump 63, and then the chassis sheet metal in the spray tank 501 is sprayed with paint through the nozzle 61. During the process, excess paint automatically drips into the liquid return funnel 65 and flows back into the paint box 64, so as to realize paint recovery and avoid paint waste, thereby realizing automatic spraying of paint on the chassis sheet metal from bottom to top. After spraying, it continues to move to the drying tank 502, and while spraying paint, starts the constant temperature electric heating plate 71 and the fan 72 to blow a steady stream of hot air onto the chassis sheet metal that has just been sprayed with paint, so as to quickly dry it and allow the paint to dry quickly, thereby avoiding damage to the paint surface caused by the paint not being dried and fixed in the later stage, and realizing integrated spraying and drying, which is automatic, has a simple overall structure and high spraying process efficiency.
