Description

Technical Field

[0001] This utility model relates to the field of automotive coating technology, and in particular to a drying device for cleaning paint mist from the surface of an atomizer. Background Technology

[0002] In automotive body painting workshops, paint mist generated during atomizer spraying adheres to the atomizer surface. It undergoes pulse cleaning using solvent and air sprayed from a surface cleaner, followed by drying with compressed air. Due to differences in paint viscosity and limitations on cleaning efficiency, the total cleaning time is constrained. This results in some paint colors not being completely dried after cleaning, leading to increased maintenance frequency. If not addressed promptly, paint mist will fall onto the car body surface, forming dirt spots and solvent spots, causing paint film defects. Furthermore, the adhering cleaning agent can melt the atomizer casing, further contaminating the paint. This reason accounts for 20% of all rework and repainting issues. Additionally, some solid color paints, due to their high viscosity, present the most severe problems during spraying. Therefore, when cleaning is insufficient, manual wiping and drying are necessary to maintain production rhythm and product quality. Residual paint fumes can pose health risks. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise explicitly specified and limited, the embodiments and features described in the embodiments of this application can be combined with each other. In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-4As shown: A drying device for cleaning paint mist on the surface of an atomizer includes a drying ring; the drying ring includes an upper ring 2, a lower ring 4 and a connecting bracket 3; the connecting bracket 3 is provided between the upper ring 2 and the lower ring 4; the upper ring 2, the lower ring 4 and the connecting bracket 3 are all hollow tube structures and are interconnected; a plurality of air holes 1 are provided on the upper ring 2.

[0024] The upper ring 2 is a circular ring.

[0025] Several air holes 1 are evenly distributed on the inner side of the upper ring 2. Furthermore, several air holes 1 are located below the axis of the upper ring 2. In this example, forty holes with a diameter of 1 mm are drilled at intervals 45° downward from the horizontal axis of the upper ring 2, which can achieve uniform ring-shaped air blowing.

[0026] The lower ring 4 is a circular ring.

[0027] The diameter of the lower ring 4 is larger than the diameter of the upper ring 2. In this embodiment, the diameter of the upper ring 2 is 140 mm, and the diameter of the lower ring is 203 mm.

[0028] The connecting bracket 3 includes an inclined section and a vertical section; in this embodiment, there are two connecting brackets 3, which are arranged symmetrically.

[0029] The upper ring 2, the lower ring 4, and the connecting bracket 3 are all stainless steel hollow tubes.

[0030] The working principle involves installing the lower ring 4 of the drying ring onto the top (air outlet) of the atomizer surface cleaner (including but not limited to ABB brand T-series paint cleaner) in the painting workshop. After cleaning, the atomizer pauses briefly on the upper ring 2 of the drying ring and reciprocates under the action of the robotic arm. The compressed air from the cleaner flows upward through the air outlet and simultaneously flows at high speed through the air holes 1 of the upper ring 2 to dry the surface of the atomizer. When the drying ring is fixed to the top of the cleaner and the air holes 1 work together with the air outlet of the cleaner, the drying air area is increased, which improves the drying effect and efficiency without increasing the cleaning time.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
