[0017] Second, multiple elastic bands are provided on the outside of the protective jacket to cooperate with the robotic arm. The elastic bands can be provided at the node positions in the robotic arm so that the protective jacket can accommodate deformation paths such as displacement and rotation at the node positions, making the protective jacket more adaptable to the displacement movements of the robotic arm.

[0026] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, an embodiment of the utility model provides a surface spraying device for automobile parts, including a fixed base 1, a mechanical arm 7 is installed on the upper end of the fixed base 1, a protective mechanism is provided on the outside of the mechanical arm 7, the protective mechanism includes a lower clamping ring 3, the mechanical arm 7 is fixedly connected to a spray gun head 5 away from the fixed base 1, an upper clamping ring 6 is installed on the outside of one end of the mechanical arm 7 close to the spray gun head 5, a protective jacket 2 is fixedly connected between the upper clamping ring 6 and the lower clamping ring 3, a plurality of extension pull ropes 8 are provided on the left side of the outer end of the protective jacket 2, a plurality of convex buttons 9 are fixedly connected to the end of the extension pull rope 8 close to the protective jacket 2, and a plurality of concave buttons 10 are provided on the right side of the outer end of the protective jacket 2.

[0030] The outer side of one end of the robotic arm 7 close to the fixed base 1 is connected to the lower locking ring 3, and multiple convex buttons 9 are arranged at equal distances. The protective jacket 2 is set on the outside of the robotic arm 7, and the spray gun head 5 is connected to the outside of the material pipe. Multiple concave buttons 10 are buckled with the corresponding extension pull ropes 8. The outer end of the protective jacket 2 is fixedly connected to a flexible outer strip 11, and the inner end of the flexible outer strip 11 is slidably connected to multiple sliding inner blocks 12, and the extension pull ropes 8 corresponding to the multiple sliding inner blocks 12 are connected to each other.

[0031] Example 2

[0032] In one embodiment, a plurality of node positions 13 are provided at the outer end of the robotic arm 7, and a plurality of elastic bands 4 are fixedly connected to the outer end of the protective jacket 2. The elastic bands 4 cooperate with the robotic arm 7, and the plurality of elastic bands 4 are respectively provided on the outside of the node positions 13.

[0033] Because the flexible outer strip 11 and the sliding inner block 12 are both made of deformable rubber material, the outer end of the protective jacket 2 is fixedly connected with a corrosion-resistant coating.

[0034] When the utility model is working: this solution utilizes the mechanical arm 7 on the fixed base 1 to evenly spray the paint on the surface of the relevant automobile parts through the spray gun head 5. However, the surface of the spraying equipment without the protection of the protective cover is easily corroded by the paint adhesion, resulting in damage to the mechanical parts, increasing the cost of equipment maintenance and repair. Therefore, a protective coat 2 is provided outside the fixed base 1 to evenly enclose the outer wall surface of the mechanical arm 7 to prevent the paint sprayed from the spray gun head 5 from adhering to the outside of the mechanical arm 7. When the protective coat 2 is provided outside the mechanical arm 7, a plurality of convex buttons 9 and concave buttons 10 outside the mechanical arm 7 can be used to snap together to limit the protective coat 2 outside the mechanical arm 7. Improve the matching degree between the protective jacket 2 and the robotic arm 7, and use the flexible outer strip 11 outside the robotic arm 7 to slide and connect the sliding inner block 12, adjust the specific position of the extension rope 8, and reinforce and engage the key limit position of the robotic arm 7, which is conducive to the reasonable distribution and utilization of multiple extension ropes 8, making the installation adaptability of the protective jacket 2 outside the robotic arm 7 higher. At the same time, multiple elastic bands 4 that cooperate with the robotic arm 7 are set outside the protective jacket 2. The elastic band 4 can be set at the node position 13 in the robotic arm 7, so that the protective jacket 2 can accommodate the displacement and rotation and other deformation paths of the node position 13, so that the protective jacket 2 is more adapted to the displacement movement of the robotic arm 7.

[0035] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in this utility model, and such modifications or substitutions are intended to fall within the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model shall be based on the scope of protection of the claims.
