[0017] This application uses the powder coating production of automotive glass as an example to introduce the structure and usage of the powder coating equipment described herein. The powder coating equipment provided in this application is not only suitable for automotive glass powder coating but also for powder coating applications of other products, specifically: A powder coating device includes a flipping mechanism 1 and a spraying mechanism 2. The flipping mechanism 1 includes a support frame 11 and a flipping frame 12. The support frame 11 is horizontally positioned. The nozzle of the spraying mechanism 2 is movably mounted on a first side of the support frame 11. The flipping frame 12 is rotatably connected to the first side of the support frame 11. By setting the flipping mechanism 1, the flipping frame 12 in the flipping mechanism 1 is rotatable, so that after the product is placed on the flipping frame 12, the setting angle of the product can be adjusted according to the powder coating requirements. And by setting the spraying mechanism 2, and the nozzle of the spraying mechanism 2 is movable, the nozzle of the spraying mechanism 2 sprays powder onto the product according to a preset trajectory, so that the powder coating area can fully cover the glass surface and the powder coating thickness is uniform.

[0018] In some embodiments, the tilting frame 12 includes at least one tilting rod 121; one end of the tilting rod 121 is rotatably connected to a first side of the support frame 11. By assembling the tilting frame 12 with at least one tilting rod 121, the weight of the tilting frame 12 can be reduced, which is more conducive to tilting control.

[0019] In some embodiments, a roller 122 is provided along the length of the flipping rod 121; the distance from the center of the roller 122 to the surface of the flipping rod 121 is less than the radius of the roller 122. By providing the roller 122 on the flipping rod 121 and forming a support surface with the roller 122 to support the product surface, and by using a flexible material such as rubber to form the roller 122, scratches on the product surface can be avoided.

[0020] In some embodiments, the flipping mechanism 1 further includes a rotating rod 123 and a motor 124; the rotating rod 123 is disposed on the first side of the flipping frame 12; one end of the flipping rod 121 is connected to the rotating rod 123; the motor 124 is connected to the rotating rod 123 and drives the rotating rod 123 to rotate. By driving the rotating rod 123 to rotate through the motor 124, the flipping rod 121 is rotated, thereby adjusting the setting angle of the product.

[0021] In some embodiments, a limiting block 3 is provided at one end of the flipping rod 121 that is connected to the support frame 11. By providing the limiting block 3 on the flipping rod 121, the product on the flipping rod 121 can be supported when the flipping rod 121 is rotated.

[0022] In some embodiments, at least two transfer rollers 13 are provided on the support frame 11; a flipping rod 121 is disposed between two adjacent transfer rollers 13. By providing transfer rollers 13 on the support frame 11, the products can be loaded and unloaded through the transfer rollers 13; and the transfer rollers 13 and the flipping rod 121 are spaced apart to avoid interference between the transfer rollers 13 and the flipping rod 121.

[0023] In some embodiments, the rolling direction of the transfer roller 13 is different from the rolling direction of the roller 122 on the flipping frame 12. By setting the rolling direction of the transfer roller 13 and the rolling direction of the roller 122 on the flipping frame 12 to be different, mutual interference between processes is avoided.

[0024] In some embodiments, the height of the support surface of the transfer roller 13 is the same as the height of the support surface of the tilting frame 12 when it is horizontal; the tilting frame 12 can be rotated to a height lower than the support surface of the transfer roller 13. By making the falling height of the tilting frame 12 lower than the height of the support surface of the transfer roller 13, the support of the tilting frame 12 after falling is automatically changed from being supported by the tilting frame 12 to being supported by the transfer roller 13, thereby realizing the transfer of products.

[0025] In some embodiments, a limiter 4 is provided below the support frame 11; the limiter 4 is located at the starting position of the flipping stroke of the flipping frame 12. By providing the limiter 4 below the support frame 11, excessive flipping of the flipping frame 12 can be prevented.

[0026] In some embodiments, a protective cover 5 is also provided on the support frame 11; the protective cover 5 has an opening only on the first side of the support frame 11. By providing the protective cover 5 on the support frame 11, the amount of dust flying into the tilting mechanism 1 can be reduced.

In this embodiment, four sets of flipping rods 121 are provided, and each flipping rod 121 has multiple sets of rollers 122 on both sides along its length. All rollers 122 work together to support the product. Each time the same product is sprayed, the flipping rod 121 is flipped to a preset position to ensure consistency in each flip.

[0030] Please refer to Figure 4 The flipping mechanism 1 also includes a rotating rod 123 and a motor 124; the rotating rod 123 is disposed on the first side of the flipping frame 12; one end of the flipping rod 121 is connected to the rotating rod 123; the motor 124 is connected to the rotating rod 123 and drives the rotating rod 123 to rotate.

In this embodiment, a total of ten sets of transmission rollers 13 and four sets of flipping rods 121 are provided, with the four sets of flipping rods 121 sequentially spaced between two transmission rollers 13. Furthermore, the rolling direction of the transmission rollers 13 is different from the rolling direction of the rollers 122 on the flipping frame 12. For example, in this embodiment, the rolling direction of the transmission rollers 13 is left-right, while the rolling direction of the rollers 122 on the flipping frame 12 is front-back. The height of the support surface of the transmission rollers 13 is the same as the height of the support surface of the flipping frame 12 when it is horizontal; the flipping frame 12 can rotate to a height lower than the support surface of the transmission rollers 13.

[0035] S1. In the initial state, the rotation angle of the flipping rod 121 is negative, that is, the flipping plane is set below the transmission plane; the glass is transmitted to the designated position of the flipping mechanism 1 through the opening of the powder spraying chamber and the transmission roller 13.

[0036] S2. Control the flip lever 121 to rotate forward, so that the glass flips to a preset angle, such as 60°~80°.

[0037] S3. The robotic arm sprays powder onto the glass surface according to the trajectory set for different types of glass.

[0038] S4. After the powder coating is completed, control the flipping rod 121 to rotate in the opposite direction and flip it under the conveying plane so that the glass is placed on the conveying roller 13 and the glass is conveyed out of the opening of the powder coating room through the conveying roller 13.
