[0002] Rearview mirrors are tools used by drivers to directly obtain external information about the rear, sides, and bottom of the vehicle while seated in the driver's seat. To facilitate driver operation, prevent traffic accidents, and ensure personal safety, all countries mandate the installation of rearview mirrors on automobiles. During the manufacturing process, rearview mirrors require a painting process.

[0003] The prior art discloses a multi-functional spraying mechanism for automotive rearview mirror brackets, application number CN202322089701.4. This mechanism includes a housing and a drying chamber located on top of the housing. The drying chamber contains a drying mechanism extending into the housing, and the housing contains a clamping mechanism. The drying mechanism includes a fan fixedly connected to the inside of the drying chamber. A heating wire is fixedly connected to the bottom of the fan inside the drying chamber. A connecting pipe extending into the housing is fixedly connected to the bottom of the drying chamber, and a jet nozzle is fixedly connected to the bottom of the connecting pipe inside the housing. This multi-functional spraying mechanism for automotive rearview mirror brackets, by incorporating a fan and heating wire, facilitates the transfer of heat generated by the heating wire into the housing. The connecting pipe and jet nozzle enable rapid drying. A dustproof net prevents external dust from entering the drying chamber.

[0004] However, in the above scheme, the drying mechanism is installed above the spraying mechanism. During the drying stage, the spray gun of the spraying mechanism is in a high-temperature environment for a long time, which not only shortens the service life of the spray gun, but also causes the spray gun nozzle to become clogged. In addition, it can only be painted once, which will cause paint peeling or color difference, which is not conducive to the high-quality painting of the rearview mirror. Utility Model Content

[0027] According to an embodiment of the present invention, a spraying and drying integrated device for the surface of a rearview mirror is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a rearview mirror surface spraying and drying integrated device according to an embodiment of the present invention includes a housing 1. The housing 1 is internally divided into a spraying chamber 2 and a conveying chamber 3, with the spraying chamber 2 located above the conveying chamber 3.

[0029] In one embodiment, a threaded post 23 is welded to the top of the mounting post 6. A mounting hole 24 is provided at the center of the rearview mirror positioning model 7 corresponding to the threaded post 23, and the cross-section of the mounting hole 24 is T-shaped. The threaded post 23 extends to the inside of the mounting hole 24, and a nut 25 is threadedly installed at the upper end of the threaded post 23. With this structure, by unlocking the nut 25 threadedly installed at the upper end of the threaded post 23, the nut 25 is disengaged from the mounting hole 24 at the center of the rearview mirror positioning model 7, so that the rearview mirror positioning model 7 is separated from the mounting post 6. This makes it easy to replace the rearview mirror positioning model 7 of a suitable size according to the actual rearview mirror size, thereby meeting the positioning requirements of rearview mirrors of different sizes.

[0030] In one embodiment, a paint baffle 10 is installed in front of the spray gun 15 of both the primer spraying unit 5 and the topcoat spraying unit 13, and the surface of the paint baffle 10 has a rectangular opening corresponding to the spray gun 15. This structure can block paint powder or paint liquid particles in the air and reduce contamination of the primer spraying unit 5 and the topcoat spraying unit 13.

[0031] In one embodiment, a blower fan 11 is installed inside the drying chamber 9, and the blower fan 11 is composed of a drive unit and an impeller installed at its output end. The air outlet at the bottom of the drying chamber 9 extends to the inside of the spraying chamber 2, and an electric heating wire 12 is installed on the lower part of the inside of the drying chamber 9 corresponding to the blower fan 11. Furthermore, a ring-shaped ventilation mesh is installed on the top surface of the drying chamber 9 corresponding to the blower fan 11. With this structure, the heat generated by the electric heating wire 12 is blown onto the chain conveyor belt 4 by the blower fan 11 to achieve the drying treatment after painting, which is beneficial to maintaining the curing effect of the paint and facilitates the subsequent application of topcoat.

[0032] In one embodiment, a partition is provided between the spraying chamber 2 and the conveying chamber 3, and the surface of the partition has an I-shaped clearance opening corresponding to the mounting column 6. With this structure, it is easy to make way for the mounting column 6 so that it can pass through the partition, and the two do not interfere with each other.

[0033] In one embodiment, the rearview mirror positioning model 7 is composed of an arc-shaped protrusion integrally injection molded from a substrate and its top surface, and the arc-shaped protrusion of the rearview mirror positioning model 7 is adapted to the contour of the concave surface of the rearview mirror housing 1.

[0034] In one embodiment, the upper end of the angle adjustment seat 16 has a U-shaped structure, and a protective shell is installed on the side of the angle adjustment seat 16 corresponding to the motor 17. With this structure, the U-shaped structure of the angle adjustment seat 16 is used to install the spray gun 15, which facilitates the angle adjustment of the spray gun 15, while the protective shell is used to prevent paint powder from contaminating the motor 17.

[0035] Working principle: First, the mechanical claw of a six-axis robot grasps the rearview mirror to be painted and extends it towards the feed inlet 8, so that the rearview mirror is upside down on the rearview mirror positioning model 7 on the top of the mounting support 6. Then, the chain conveyor belt 4 is started to transport the rearview mirror, so that it passes sequentially through the installation areas of the primer spraying unit 5 and the topcoat spraying unit 13. The spray guns 15 of the primer spraying unit 5 and the topcoat spraying unit 13 spray the primer and topcoat onto the rearview mirror on the chain conveyor belt 4. Then, the two drying chambers 9 installed on the top surface of the housing 1 are started to work, so that the fan 11 blows the heat generated by the heating wire 12 onto the chain conveyor belt 4, realizing the sequential spraying of primer and topcoat on the rearview mirror and secondary paint drying treatment. When it is necessary to adjust the spraying angle of the spray gun 15, the angle adjustment seat is activated. When the motor 17 on the 16 is working, the transmission belt 22 at the output end of the motor 17 drives the lower shaft 20 to rotate. Since the lower gear 21 of the lower shaft 20 is meshed with the upper gear 19 of the upper shaft 18, the lower shaft 20 drives the upper shaft 18 to rotate, causing the spray gun 15 to swing up and down within the angle adjustment seat 16. This allows the nozzle of the spray gun 15 to spray paint the rearview mirror evenly. When the rearview mirror positioning model 7 is replaced, the nut 25 installed on the upper thread of the threaded post 23 is unlocked, causing the nut 25 to disengage from the mounting hole 24 in the center of the rearview mirror positioning model 7. This separates the rearview mirror positioning model 7 from the mounting support 6, making it easy to replace the rearview mirror positioning model 7 with a suitable size according to the actual rearview mirror size, thereby meeting the positioning requirements of rearview mirrors of different sizes.
