[0041] In this embodiment, when the main arm beam component of the automobile moves to the first-level toggle arm 22, in order to ensure that the main arm beam component of the automobile can be calibrated in the central area of ​​the surface of the conveyor chain 11, the first-level rotating shaft 21 installed at the bottom of the fixed seat 2 can then drive the first-level toggle arm 22 to rotate, and the first-level guide wheel 23 on the first-level toggle arm 22 moves close to the main arm beam component of the automobile, thereby guiding and converging the moving position of the main arm beam component of the automobile, thereby adjusting the position of the main arm beam component of the automobile on both sides, thereby ensuring accurate painting of the surface of the main arm beam component of the automobile.

[0042] The component surface oil spraying unit is arranged on both sides of the spraying bin 3 and is used to evenly spray paint on the surface of the calibrated automobile component;

[0043] The component surface oil spraying unit includes a mounting frame 33, an injection groove 31 is arranged at the top center area of ​​the spray bin 3, the injection groove 31 runs through the top of the spray bin 3, the mounting frame 33 is installed at the top of the spray bin 3, an electric drive gear 34 is installed on the mounting frame 33, an arc bottom shell 5 and an arc top shell 51 are fixed in the injection groove 31, an arc slider 52 is slidably installed between the arc bottom shell 5 and the arc top shell 51, an arc tooth plate 53 is installed on the outer surface of the arc slider 52, the arc tooth plate 53 is meshed with the electric drive gear 34, and an electromagnetic liquid spraying pipe 54 is arranged in an arc shape at the bottom of the arc slider 52;

[0044] In this embodiment, the surface of the main arm beam component of the automobile is evenly sprayed with paint through three groups of electromagnetic spray tubes 54 evenly distributed in an arc shape. In order to ensure that the inner and outer areas of the main arm beam component of the automobile can be evenly painted, the two groups of electric drive gears 34 can be driven to rotate, thereby driving the arc-shaped tooth plate 53 to swing back and forth inside the arc-shaped bottom shell 5 and the arc-shaped top shell 51 through meshing transmission. During the reciprocating swing of the arc-shaped tooth plate 53, the three groups of electromagnetic spray tubes 54 are driven to spray paint on the inner and outer areas of the surface of the main arm beam component of the automobile in an arc-shaped motion state, thereby further improving the painting effect on the surface of the main arm beam component of the automobile.

[0045] A groove 32 is arranged on one side of the top of the spray bin 3, and an airflow drying unit for the paint on the surface of the parts is arranged in the area of ​​the groove 32.

[0046] The airflow drying unit for paint on the surface of components includes a secondary rotating shaft 321, which is installed inside the groove 32. A rotating arm 6 is sleeved on the rotating end of the secondary rotating shaft 321. An air chamber 62 is embedded in the surface of the rotating arm 6.

[0048] In this embodiment, after the surface of the main arm beam component of the automobile is evenly sprayed with paint, the secondary rotating shaft 321 is driven again to rotate and drive the rotating arm 6 and the baffle 61 to partially lift up. Then, the main arm beam component of the automobile is transported out of the spray bin 3 driven by the conveying chain plate 12. Then, the air bin 62 embedded in the rotating arm 6 and the electromagnetic nozzle 63 at the bottom of the air bin 62 will evenly spray the hot gas onto the surface of the main arm beam component of the automobile, thereby accelerating the adhesion efficiency of the paint on the surface of the main arm beam component of the automobile.

[0049] The inner cavity of the spray bin 3 is symmetrically provided with a paint replenishing spraying unit for the side surface of the parts.

[0050] The part side surface paint replenishing spraying unit includes a splash-proof inner shell 4, which is arranged in two groups, and each group of splash-proof inner shells 4 is arranged in two pairs. The splash-proof inner shell 4 is installed on the inner wall of the spray bin 3, and a spray gap 41 is arranged between adjacent splash-proof inner shells 4. A spray bin 42 is arranged in the spray gap 41 area. The spray bin 42 is fixed to one side of the splash-proof inner shell 4, and a lateral nozzle 421 is arranged on the surface of the spray bin 42. A pressure sensor 422 is installed on the other side of the spray bin 42.

[0051] The paint replenishing spraying unit for the side surface of the part also includes a triggering part, which includes a side platform 43. The side platform 43 is installed on the outside of the splash-proof inner shell 4, and a transverse through groove 44 is arranged on one side of the side platform 43 near the spray gap 41. A mounting groove 431 is arranged on the top of the side platform 43, and the mounting groove 431 is connected to the transverse through groove 44. A retaining frame 45 is installed in the transverse through groove 44 area. A movable column 46 is slidably installed in the retaining frame 45, and one end of the movable column 46 passes through the retaining frame 45 and is inserted into the transverse through groove 44. An arc-shaped contact plate 48 is installed on one end of the movable column 46. The outer surface of the arc-shaped contact plate 48 is smoothly set, and a buffer spring 47 is sleeved on the surface of the movable column 46. The two ends of the buffer spring 47 are respectively fixed to the inner side of the arc-shaped contact plate 48 and the outer side of the retaining frame 45, and the outer surface of the arc-shaped contact plate 48 is in movably contact with the inner surface of the arc-shaped slider 52.

[0052] In this embodiment, during the reciprocating swing of the arc-shaped tooth plate 53, when the arc-shaped slider 52 at the bottom of the arc-shaped tooth plate 53 moves to the side platform 43 area, one end of the arc-shaped slider 52 will be inserted into the mounting groove 431 so as to contact the smooth surface of the arc-shaped contact plate 48, and the arc-shaped slider 52 will squeeze the arc-shaped contact plate 48, thereby squeezing the pressure sensor 422 through the movable column 46 connected to the arc-shaped contact plate 48. When the pressure sensor 422 is pressurized, it transmits a signal to the external control module, and the control module integrates the signal and sprays paint on the lateral bottom area of ​​the main arm beam component of the automobile, and then sprays paint on the lateral bottom area of ​​the main arm beam component of the automobile through the lateral nozzle 421 on the surface of the spray bin 42, thereby ensuring uniform painting on the surface of the main arm beam component of the automobile.

[0053] Working principle: During the use of the device, the operator first places the part of the automobile main arm beam component that needs to be painted on the surface of the conveyor chain plate 12, and then drives the conveyor chain belt 11 to rotate, the conveyor chain belt 11 drives the conveyor chain plate 12 to move, and the conveyor chain plate 12 drives the automobile main arm beam component to move toward the spray bin 3. When the automobile main arm beam component moves to the first-level toggle arm 22, in order to ensure that the automobile main arm beam component can be calibrated in the central area of ​​the surface of the conveyor chain belt 11, the first-level rotating shaft 21 installed at the bottom of the fixed seat 2 can then drive the first-level toggle arm 22 to rotate, and the first-level guide wheel 23 on the first-level toggle arm 22 moves close to the automobile main arm beam component, thereby guiding and converging the moving position of the automobile main arm beam component, so as to adjust the position of the automobile main arm beam component on both sides;

[0054] When the larger automobile main arm beam component is calibrated and placed in the central area of ​​the surface of the conveyor chain belt 11 under the rolling conveyance of the primary guide wheel 23, the conveyor chain plate 12 continues to move, thereby driving the larger automobile main arm beam component to enter the spray bin 3 for the painting step, and then drives the secondary rotating shaft 321 to rotate, and the rotation of the secondary rotating shaft 321 drives the rotating arm 6 and the blocking rod 61 to rotate and lower, thereby partially blocking the automobile main arm beam component inside the spray bin 3, and then operates the arc-shaped electromagnetic spray pipe 54 to spray paint the surface of the automobile main arm beam component in an arc shape evenly;

[0055] When arc spraying is performed on the surface of the main arm beam component of the automobile, the surface of the main arm beam component of the automobile is uniformly sprayed with paint through three groups of electromagnetic liquid spraying tubes 54 evenly distributed in an arc shape. In order to ensure that the inner and outer areas of the main arm beam component of the automobile can be evenly painted, the two groups of electric drive gears 34 can be driven to rotate, thereby driving the arc gear plate 53 to reciprocate inside the arc bottom shell 5 and the arc top shell 51 through meshing transmission. During the reciprocating swing of the arc gear plate 53, the three groups of electromagnetic liquid spraying tubes 54 are driven to spray paint on the inner and outer areas of the surface of the main arm beam component of the automobile in an arc motion state;

[0056] During the reciprocating swing of the arc tooth plate 53, when the arc slider 52 at the bottom of the arc tooth plate 53 moves to the side platform 43 area, one end of the arc slider 52 will be inserted into the mounting groove 431 so as to contact the smooth surface of the arc contact plate 48, and the arc slider 52 will squeeze the arc contact plate 48 and thus squeeze the pressure sensor 422 through the movable column 46 connected to the arc contact plate 48. When the pressure sensor 422 is pressurized, the signal is transmitted to the external control module, and the control module integrates the signal and then sprays paint on the lateral bottom area of ​​the main arm beam component of the automobile, and then sprays paint on the lateral bottom area of ​​the main arm beam component of the automobile through the lateral nozzle 421 on the surface of the spray bin 42;

[0057] When the surface of the main arm beam component of the automobile is evenly sprayed with paint, the secondary rotating shaft 321 is driven again to rotate and drive the rotating arm 6 and the baffle 61 to partially lift up. Then, the main arm beam component of the automobile is transported out of the spray bin 3 driven by the conveying chain plate 12. Then, the air bin 62 embedded in the rotating arm 6 and the electromagnetic nozzle 63 at the bottom of the air bin 62 will evenly spray the hot gas onto the surface of the main arm beam component of the automobile, thereby accelerating the adhesion efficiency of the paint on the surface of the main arm beam component of the automobile. At the same time, the high-speed fan 73 in the mounting seat 7 area on the top of the air bin 62 will accelerate the flow rate of the hot gas.
