Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint spraying technology, and in particular to a truck bed spraying mechanism. Background Technology
[0002] A paint spray gun is a tool used for spraying paint on product surfaces and is a type of coating equipment. It uses compressed air to atomize paint into fine droplets, which are then sprayed onto the surface of the object being coated. Compared to traditional manual brushing, paint spray guns are more efficient, produce better results, and are 5-10 times more effective, producing a more delicate, smooth, and uniform coating. Current technologies also utilize automated equipment, such as robotic arms, to drive the spray guns. However, for products like truck beds that require coating over a large area, the robotic arm needs to be long and flexible enough. Using a robotic arm for truck beds, where the painting requirements are not high, increases processing costs. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a truck bed spraying mechanism that is simple in structure and easy to use.
[0004] This utility model discloses a truck bed spraying mechanism, which includes a base for placing the truck bed, mounting brackets on both sides of the base, a first direction moving component that can reciprocate along a first direction, a second direction moving component that can reciprocate along a second direction, and a third direction moving component that can reciprocate along a third direction. The first, second, and third directions are perpendicular to each other. The end of the third direction moving component is provided with a rotating component that can rotate around the third direction. The rotating component includes a base plate and a cylinder disposed on the base plate. The movable end of the cylinder and connecting lugs on both sides of the movable end are rotatably connected to a spray gun mounting plate, and a spray gun is mounted on the spray gun mounting plate.
[0005] In one or more embodiments of this utility model, the rotating assembly further includes a base plate installed at the end of a third-direction moving assembly. A fourth motor is provided on the base plate, and the output end of the fourth motor is rotatably connected to a first rotating plate. The cylinder is installed on the first rotating plate along the third direction. The movable end of the cylinder is hinged to one end of a second rotating plate through a connecting plate. The connecting lugs on both sides of the movable end of the cylinder are rotatably connected to the other end of the second rotating plate. The spray gun mounting plate is fixedly installed on the second rotating plate.
[0006] In one or more embodiments of this utility model, the connecting ear plate is rotatably mounted to the second rotating plate via a rotating shaft and a bearing.
[0007] In one or more embodiments of this utility model, the mounting bracket is provided in two sets, and each set of mounting brackets is respectively installed on both sides of the base along a first direction.
[0008] In one or more embodiments of the present invention, the first direction moving component includes a first mounting base mounted on a mounting bracket, the first mounting base having a slide rail along a first direction, a slider mounted on the slide rail, a moving block mounted on the slider, a first moving plate mounted on the moving block, a first motor mounted on the first moving plate, the output end of the first motor being rotatably connected to a first rack via a gear, and the first rack being mounted on the first mounting base along the first direction.
[0009] In one or more embodiments of this utility model, the movable block is a U-shaped movable block, and a guide plate is installed on the first mounting base. When the movable block reciprocates along the first direction, the guide plate passes through the groove of the movable block.
[0010] In one or more embodiments of the present invention, the second directional moving component includes a second mounting base, a second moving plate, a second rack, and a second motor. The second mounting base is mounted on a first mounting base along a second direction, and a second rack is mounted on the second mounting base along the second direction. The second moving plate is slidably mounted on the second mounting base along the second direction, and the second motor is mounted on the second moving plate. The output end of the second motor meshes with the second rack through a gear.
[0011] In one or more embodiments of this utility model, the third-direction moving component includes a third mounting base, a third moving plate, a third rack, and a third motor. One end of the third moving plate is fixedly mounted on a second moving plate, and the other end of the third moving plate is slidably mounted on the second mounting base along a second direction. The third mounting base is slidably mounted on the third moving plate along a third direction. A third rack is mounted on the third mounting base along a third direction upward. The third motor is fixedly mounted on the third moving plate, and the output end of the third motor meshes with the third rack through a gear.
[0012] In one or more embodiments of this utility model, the third mounting base is hollow, the base plate is mounted on the bottom of the third mounting base, and the fourth motor is mounted on the base plate inside the third mounting base.
[0013] The beneficial effects of this utility model are as follows: The spraying mechanism of this utility model is based on a multi-degree-of-freedom motion system, and achieves spatial positioning through orthogonally arranged X, Y, and Z three-axis moving components. Each moving component adopts a linear guide rail and a drive mechanism, wherein the Z-axis moving component integrates a dual-axis rotation module at its end, including a pitch axis and a horizontal rotation axis. The spray gun is mounted on the rotation module, and the moving and rotating components are controlled by a servo system, enabling the spray gun to translate along three-dimensional directions, while also having pitch angle adjustment and horizontal rotation capabilities, forming a composite motion mode of "three translations + two rotations".
[0014] This invention utilizes a combination of multi-degree-of-freedom motion to enable the spray gun to precisely cover complex surfaces such as the inner wall, top, and sides of the truck bed. X and Y axis movement controls the spray gun's longitudinal and transverse scanning along the truck bed, while the Z axis adjusts the spraying height. The pitching motion of the rotating module allows the spray gun to be vertically aligned with inclined or curved structures, and horizontal rotation enables continuous operation around the circumference of the truck bed. This ensures that all exposed surfaces, except the bottom of the truck bed, are uniformly coated, effectively solving the problems of low coating efficiency and high equipment cost inherent in traditional equipment.
[0015] This design simplifies complex motion mechanisms into a modular assembly structure. The three-way moving component and the dual-axis rotating module are connected via standardized interfaces, significantly reducing component complexity. The moving component uses a lightweight rigid frame, which significantly reduces manufacturing costs while ensuring positioning accuracy. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0024] In the description of this utility model, it should be understood that the terms "vertical", "horizontal", "top", "bottom", "upper", "lower", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] It should be noted that, unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0026] As described in the background section, existing spraying mechanisms are not suitable for spraying truck beds, especially dump truck beds.
[0027] For the above issues, please refer to the appendix. Figure 1As shown, this utility model provides a truck bed spraying mechanism, including a base 200 for placing a truck bed 100. Mounting brackets 300 are provided on both sides of the base 200. Two sets of mounting brackets 300 are provided, each set mounted on both sides of the base 200 along a first direction X. A first-direction moving component 400 reciprocates along the first direction X on the mounting bracket 300. A second-direction moving component 500 reciprocates along a second direction Y on the first-direction moving component 400. A third-direction moving component 600 reciprocates along a third-direction Z on the second-direction moving component 500. The first direction X, second direction Y, and third-direction Z are perpendicular to each other. A rotating component 700 rotatable around the third-direction Z is provided at the end of the third-direction moving component 600. The rotating component 700 includes a base plate 71 and a cylinder 74 mounted on the base plate 71. The movable end 741 of the cylinder 74... The connecting ear plates 742 on both sides of the movable end 741 are rotatably connected to the spray gun mounting plate 76, and the spray gun 800 is mounted on the spray gun mounting plate 76. Therefore, in this embodiment, the spray gun 800 can reciprocate along the first direction X, the second direction Y and the third direction Z. At the same time, the spray gun 800 can also rotate around the first direction X and the third direction Z. For the truck bed 100, it is necessary to spray the inner bottom and sides as well as the outer sides, but the outer bottom does not need to be sprayed. Therefore, in this utility model, the spraying mechanism can complete the automated spraying of the truck bed 100 using only three-directional moving components, a rotating motor and a cylinder.
[0028] In a further embodiment, see Appendix Figure 2 As shown, the first direction moving component 400 includes a first mounting base 41 mounted on a mounting bracket 300. The first mounting base 41 has a slide rail 42 along the first direction X. A slider 43 is mounted on the slide rail 42. A moving block 44 is mounted on the slider 43. A first moving plate 45 is mounted on the moving block 44. A first motor 48 is mounted on the first moving plate 45. The output end of the first motor 48 is rotatably connected to a first rack 47 via a gear 46. The first rack 47 is mounted on the first mounting base 41 along the first direction X. In this embodiment, the moving block 44 is a U-shaped moving block. A guide plate 49 is mounted on the first mounting base 41. When the moving block 44 reciprocates along the first direction X, the guide plate 49 passes through the groove of the moving block 44 to ensure accuracy during reciprocating motion. Other moving components in this invention, the second moving component 500 and the third moving component 600, all have the same structure as the guide plate 49 and the moving block 44.
[0029] In a further embodiment, see Appendix Figure 3As shown, the second direction moving assembly 500 includes a second mounting base 51, a second moving plate 52, a second rack 53, and a second motor 54. The second mounting base 51 is mounted on the first mounting base 41 along the second direction Y. The second rack 53 is mounted on the second mounting base 51 along the second direction Y. The second moving plate 52 is slidably mounted on the second mounting base 51 along the second direction Y. The second motor 54 is mounted on the second moving plate 52. The output end of the second motor 54 meshes with the second rack 53 through a gear. The third-direction moving component 600 includes a third mounting base 61, a third moving plate 62, a third rack 63, and a third motor 64. One end of the third moving plate 62 is fixedly mounted on the second moving plate 52, and the other end of the third moving plate 62 is slidably mounted on the second mounting base 51 along the second direction Y. The third mounting base 61 is slidably mounted on the third moving plate 62 along the third direction Z. The third rack 63 is mounted on the third mounting base 61 along the third direction Z. The third motor 64 is fixedly mounted on the third moving plate 62, and the output end of the third motor 64 meshes with the third rack 63 through gears.
[0030] In a further embodiment, see Appendix Figure 4 As shown, the rotating assembly 700 includes a base plate 71 mounted on the end of the third-direction moving assembly 600. A fourth motor 73 is mounted on the base plate 71. The output end of the fourth motor 73 is rotatably connected to a first rotating plate 72. A cylinder 74 is mounted on the first rotating plate 72 along the third direction Z. The movable end 741 of the cylinder 74 is hinged to one end of a second rotating plate 75 through a connecting plate 77. Connecting ear plates 742 on both sides of the movable end 741 of the cylinder 74 are rotatably connected to the other end of the second rotating plate 75. A spray gun mounting plate 76 is fixedly mounted on the second rotating plate 75. The connecting ear plates 742 are rotatably mounted to the second rotating plate 75 through a rotating shaft 78 and a bearing 79. In this embodiment, the third mounting base 61 is hollow. The base plate 71 is mounted on the bottom of the third mounting base 61, and the fourth motor 73 is mounted on the base plate 71 inside the third mounting base 61.
[0031] Workflow: The three-way moving component in this invention delivers the spray gun 800 to a preset position, adjusts the circumferential angle by horizontal rotation, and controls the pitch angle with a cylinder to adapt to curved surfaces or sharp edges. Through a pre-set spraying trajectory, the spray gun 800 can automatically cover all areas of the truck bed 100 except for the inner bottom surface, including the inner and outer walls, top surface, and complex geometric structures, while avoiding the bottom support components. In this embodiment, each moving component adopts a modular design. The X-axis U-shaped moving block cooperates with the guide plate to ensure motion accuracy, while the Y and Z axes are driven stably through gear and rack transmission. Compared to traditional multi-axis robotic arms, this solution combines three translational (X / Y / Z) and two rotational (around the Z-axis and around the X-axis) degrees of freedom, simplifying the mechanical structure, reducing manufacturing costs, and ensuring no blind spots in spraying. It is suitable for the automated surface treatment needs of large components such as engineering vehicles.
[0032] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
