[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application. In addition, in the description of the present application, the term "including" means "including but not limited to". The terms first, second, third, etc. are only used for marking and do not impose numerical requirements or establish an order.

[0025] Such as Figure 1 and Figure 2As shown, the spraying device of the present application is a DISK electrostatic spraying device. DISK electrostatic spraying utilizes the action of a high-voltage (30 - 100 KV) electrostatic field. Through the high-speed rotation of a spinning disc, paint particles (paint discharge rate: 0 - 500 cc / min) are dispersed by centrifugal force and carry a high-voltage negative charge. Under the action of the electric field, they are evenly dispersed and directionally adsorbed (2 seconds - 2.5 seconds / root, workpiece length 2.4 meters), thereby forming a uniform and firm coating layer on the workpiece surface. In order to achieve the spraying of the composite material frame by the DISK electrostatic spraying device, the present application provides the following composite material frame spraying device. The spraying structure main body of this spraying device is a DISK electrostatic spraying device. This spraying device has a spraying chamber 110 and has a first direction X and a second direction Y. In some embodiments, the first direction X is perpendicular or approximately perpendicular to the second direction Y. The spraying device includes a track 101 extending along the first direction X. The track 101 can be driven by a motor and move along the first direction X. The track 101 is connected to at least one first hanger 102. In some specific embodiments, the track 101 is connected to multiple first hangers 102, and the multiple first hangers 102 are spaced along the first direction X. The lower end of the first hanger 102 is connected to a second hanger 103. The second hanger 103 extends along the second direction Y. The second hanger 103 is detachably connected to the first hanger 102. In practical applications, the distance between the composite material frames can also be adjusted by adjusting the number and spacing of the second hangers suspended on the first hanger 102. The present application realizes the material spraying of the composite material frame by the DISK electrostatic spraying device by arranging a hanging mechanism in the spraying chamber 110 of the spraying device, thereby improving production efficiency.

[0026] In some embodiments, the composite material frame 200 is connected to the second hanger 103. A first connecting member 104 is provided at the end of the second hanger 103. The composite material frame 200 has a cavity 210. The first connecting member 104 is inserted into the cavity 210 of the composite material frame 200, thereby realizing the connection between the second hanger 103 and the composite material frame 200. In some specific applications, the second hanger 103 is made of a wire with a diameter of 3 - 5 mm.

[0027] In some embodiments, the first connecting member 104 includes a guiding end 1041. The width W1 of the guiding end 1041 is smaller than the width W2 of the cavity 210. This guiding end 1041 facilitates the insertion of the first connecting member 104 into the cavity of the composite material frame 200, improving production efficiency.

[0028] In some embodiments, the first connecting member 104 further includes a first connecting end 1042 and a second connecting end 1043. The first connecting end 1042 and the second connecting end 1043 are disposed opposite to each other, and the first connecting end 1042 and the second connecting end 1043 are respectively in contact with the inner surface of the cavity 210. The first connecting end 1042 is connected to the first hanger 102 through a first connecting rod 1044. In this application, by providing the first connecting end 1042 and the second connecting end 1043 which are disposed opposite to each other, and connecting the two connecting ends through an inclined connecting member in the middle, the connection of the composite material frame can be realized, the connection area is reduced, the friction force of inserting the first connecting member 104 is lowered, the operation difficulty is increased, and the production efficiency is improved.

[0029] As Figure 3 and Figure 4 shown, in some specific embodiments, a first transition region 1045 is provided between the first connecting end 1042 and the first connecting end 1042. The first transition region 1045 connects the first connecting rod 1044 and the first connecting end 1042, and the first transition region 1045 extends obliquely from the bottom end of the first connecting rod 1044 towards the top end of the first connecting end 1042. A second transition region 1046 is provided between the second connecting end 1043 and the guiding end 1041. The second transition region 1046 connects the second connecting end 1043 and the guiding end 1041, and the second transition region 1046 extends obliquely from the top end of the guiding end 1041 towards the bottom end of the second connecting end 1043. The two transition regions realize the connection of the first connecting end surface 1042 and the second connecting end surface 1043 of the first connecting member 104 in the embodiments of this application, and the contact area with the inner surface of the composite material frame can be reduced. In addition, the guiding end 1041 of this application is an arc-shaped structure, and this structure can reduce the stress concentration at the bottom end of the first connecting member 104 and improve the structural stability.

[0030] The composite material frame spraying device of this application sprays the composite material frame in a hanging manner, which can reduce the hanging distance between workpieces, lower the production beat, improve the production efficiency, and the hanging method can be compatible with composite material frames of different specifications. For example, during the production process, by adding connecting devices at both ends of the composite material frame material, continuous production of long and short sides can be realized without switching. In some specific embodiments, the spraying device includes a third hanger 105, and the third hanger 105 is used to connect adjacent composite material frames 200, such as Figure 6 , Figure 7 and Figure 8As shown in the figure, the third hanger 105 includes a second connecting rod 1051 and second connectors 1052 and third connectors 1053 provided at both ends of the second connecting rod 1051. In some specific embodiments, the third hanger 105 is made of a wire with a diameter of 3-5 mm. The two ports of the third hanger 105 are open structures. Both the second connector 1052 and the third connector 1053 are U-shaped structures. The two structures are connected by the second connecting rod 1051. The structure of the third hanger 105 is simple. The third hanger 105 realizes the continuous production of the composite material frame with long and short sides, improving the production efficiency.

[0031] Suspend the composite material frame in the spraying chamber 110, and use the spraying device of the present application to spray coating particles on the composite material frame 200. After spraying, the track 101 moves horizontally to move the sprayed composite material frame out of the spraying chamber 110.
