Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy spray painting, in particular to an aluminum alloy component spray painting device. Background Art

[0002] Aluminum alloys are susceptible to corrosion from corrosive media such as oxygen, moisture, and salt in the natural environment. After painting, a protective film is formed on the surface of aluminum alloy components, which can effectively prevent these corrosive media from coming into direct contact with the aluminum alloy, thereby slowing down the corrosion rate.

[0003] At present, the existing paint spraying equipment lacks an effective device to capture paint mist during the painting process, which causes the paint mist generated around the spray gun to spread everywhere and is difficult to be effectively controlled. This not only pollutes the surrounding environment, but also makes it easy for the paint mist to form granular attachments on the surface of aluminum alloy components during the painting process. These granular attachments will greatly affect the quality of the paint, resulting in problems such as unevenness and roughness on the painted surface, reducing the appearance quality and protective performance of the aluminum alloy components. Therefore, the present application provides an aluminum alloy component painting equipment to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0023] The following describes in detail an aluminum alloy component painting system provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative methods for implementing certain known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0024] like Figure 1 - Figure 5 As shown, an embodiment of the present invention provides an aluminum alloy component painting equipment, including: a workbench 1; a placement plate 2, arranged in the workbench 1; a workpiece 3, placed on the top of the placement plate 2; a spray gun 4, arranged in the workbench 1 and located above the workpiece 3; an auxiliary component 10, arranged on the spray gun 4.

[0025] It also includes: a movable plate 9, which is arranged in the workbench 1 and is located above the spray gun 4; the auxiliary component 10 includes: a wind hood 102, which is arranged on the spray gun 4 and is trumpet-shaped; a sensor 106, which is arranged in the wind hood 102; a delivery pipe 104, which is connected and arranged on the wind hood 102 and is ring-shaped; a control valve 105, which is connected and arranged on the delivery pipe 104; the sensor 106 and the control valve 105 are electrically connected.

[0026] By setting up the wind hood 102, a local negative pressure environment is formed around the spray gun 4, and the paint mist sprayed from the spray gun 4 can be quickly sucked into the wind hood 102, reducing the diffusion time and range of the paint mist in the air. The local negative pressure environment can reduce the interference of external airflow on the flight trajectory of the paint mist, so that the paint mist sprayed from the spray gun 4 can be more stably attached to the surface of the workpiece 3; by setting up the sensor 106, the paint mist situation in the wind hood 102 can be detected, and the air intake of the control valve 105 can be adjusted according to the situation. For example, when the spray gun 4 starts spraying, the suction intensity of the exhaust hood 102 is gradually increased, and at the end of spraying, the suction intensity is gradually reduced until the spray gun 4 completely stops spraying and then returns to the initial state; when the paint mist concentration is high, the suction air volume is automatically increased, otherwise, the suction air volume is reduced.

[0027] It also includes: a channel tube 101 , one end of which is connected to the control valve 105 ; a telescopic tube 103 , one end of which is connected to the other end of the channel tube 101 and the other end of which passes through the workbench 1 .

[0028] By setting up a channel tube 101, the other end of the channel tube 101 is connected to the movable plate 9 through a connecting block, and is communicated with the telescopic tube 103 at the same time; by setting up the telescopic tube 103, one end passing through the workbench 1 can be connected to an external tube or an air pump to provide suction, and at the same time the telescopic tube 103 can move with the movable plate 9 to avoid sealing failure.

[0029] The hood 102 comprises an outer layer 1022 and an inner layer 1021 disposed within the outer layer 1022. The pores of the outer layer 1022 are larger than those of the inner layer 1021. By providing different pore sizes for the outer layer 1022 and the inner layer 1021, the paint mist sprayed from the spray gun 4 is treated in layers. The larger pores of the outer layer 1022 capture larger particles of paint mist first, while the smaller pores of the inner layer 1021 efficiently absorb fine paint mist, thereby improving the targeted and effective treatment of the paint mist.

[0030] The apparatus further comprises a partition 6 disposed on the placement plate 2 to divide the workbench 1 into two chambers. The partition 6 divides the workbench 1 into two chambers. The first chamber is used for spray painting the workpiece 3. A fan is disposed in the second chamber. The airflow generated by the fan can guide the paint mist from the first chamber into the second chamber for discharge. A purification device can be disposed in the second chamber to purify the discharged gas.

[0031] The workbench 1 further comprises two slide bars 8 disposed on the top of the inner cavity of the workbench 1 and an electric slide rail 5 disposed between the two slide bars 8. By providing the electric slide rail 5, the movement direction of the spray gun 4 can be precisely controlled, so that the spray gun 4 can spray paint along a preset path above the workpiece 3, ensuring uniformity and consistency of the paint spraying.

[0032] The top of the movable plate 9 is connected to the electric slide rail 5 , and both ends of the movable plate 9 are slidably connected to the slide bar 8 ; the conveying member 7 has one end arranged at the bottom of the movable plate 9 and the other end connected to the spray gun 4 .

[0033] By setting up a conveying member 7, the conveying member 7 can be connected to the paint storage component, and the paint can be stably conveyed to the spray gun 4, ensuring that the spray gun 4 has a continuous and stable supply of paint during the painting process. The conveying member 7 moves synchronously with the movable plate 9, thereby driving the spray gun 4 to move.

[0034] The technical solution provided by the present invention is to place the workpiece 3 on the placement plate 2, use the external controller to start the electric slide 5 and the spray gun 4, the electric slide 5 drives the movable plate 9 to move, so that the movable plate 9 slides along the slide bar 8, so that the spray gun 4 moves to spray paint the workpiece 3, and at the same time, it is connected to the telescopic tube 103 through the external tube, and a negative pressure environment is generated through the wind hood 102 to absorb the paint mist around the spray gun 4. The paint mist concentration and air flow velocity are monitored in real time through the sensor 106, and the control valve 105 is automatically adjusted according to these parameters to control the suction intensity of the wind hood 102.

[0035] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
