Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body paint touch-up spot spraying, in particular to a minimally invasive paint touch-up spot spraying device for a vehicle body paint surface. Background Art

[0002] The paint surface of the vehicle body is mainly composed of primer, midcoat, color paint and clearcoat, which together constitute the appearance of the vehicle body. Each layer has its specific function and role. The paint surface of the vehicle body is a complex and delicate system. It can not only protect the vehicle body from erosion and damage from the external environment, but also provide the vehicle with a beautiful appearance and rich color options. With the continuous advancement of technology and the continuous improvement of environmental protection standards, the performance and quality of the vehicle body paint surface will continue to improve.

[0003] Although the current minimally invasive touch-up paint spraying equipment for car body paint is easy to operate and efficient, it faces some technical difficulties when repairing minor damage. The main problem is that the paint overflows, resulting in an uneven paint surface. After the overflow, additional grinding and polishing are required to restore the smoothness, which increases the repair steps and time. If there is a lot of overflowed material and the color does not match, special attention must be paid to color matching, and the entire area may need to be re-sprayed, making the repair more difficult. In addition, it is difficult for the spot spraying equipment to accurately control the edge of the paint, and it is easy to overflow at the edge, affecting the appearance and adjacent paint surfaces, resulting in a larger repair area. After the paint overflows, it also needs to be thoroughly cleaned, which increases the cleaning workload and may extend the repair cycle. Utility Model Content

[0004] The main purpose of the utility model is to provide a minimally invasive paint touch-up spraying device for a vehicle body paint surface, which can effectively solve the problems raised in the background technology.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 4 As shown, a minimally invasive touch-up paint spot spraying device for a vehicle body includes the following main components; a paint spray gun body 1 as the main part of the device is responsible for spraying the material; a material tank 2 is installed on the paint spray gun body 1 for storing touch-up paint materials; a first adjustment head 3 and a second adjustment head 4 are installed at the nozzle of the paint spray gun body 1 for adjusting the direction and flow of spraying; a docking joint 5 is designed at the nozzle extension of the paint spray gun body 1, and the docking joint 5 is connected to a connector 6. The connector 6 is made of hard plastic material and is integrally injection-molded with the elliptical cover 7, which increases the overall durability and stability. The cross-section of the elliptical cover 7 is trapezoidal, and the cover opening is elliptical to adapt to vehicle body paint surfaces of different shapes;

[0022] When the material is sprayed out from the nozzle, it is restricted by the elliptical cover 7 to ensure that the touch-up paint material can be accurately sprayed to the minimally invasive position. The elliptical cover 7 is provided with a through hole 13, and each through hole 13 is connected to a transparent cover 8. Through the transparent cover 8, the user can clearly observe the touch-up paint position of the minimally invasive nozzle and the paint surface to ensure the accuracy of the touch-up paint; at the outer end of the elliptical cover 7, a connecting soft cover 9 is connected, and the outer end of the connecting soft cover 9 is connected to a petal-type soft cover 10. Each petal of the petal-type soft cover 10 is provided with a slit 12 to facilitate the uniform distribution of the touch-up paint material. The inner cavity of the petals of each petal-type soft cover 10 is connected to an absorbent sponge 11. When the petal-type soft cover 10 is close to the vehicle body, the absorbent sponge 11 can effectively absorb excess touch-up paint material to prevent dripping or flowing on the paint surface;

[0023] The butt joint 5 is designed as an integral part with the nozzle of the spray gun body 1, and its outer wall is provided with threads, which are adapted to the threads of the inner wall of the connector 6, so as to facilitate disassembly and replacement. The connecting soft cover 9 and the petal-shaped soft cover 10 are made of soft rubber material and adopt an integral injection molding process to ensure the sealing and stability of the connection. At the same time, the connecting soft cover 9 is hot-melted and fixed at the cover mouth of the elliptical cover 7 to ensure a firm connection.

[0024] Working process: First, install the material tank 2 on the spray gun body 1 to ensure that there is sufficient touch-up paint material in the material tank 2. Next, according to the minimally invasive position and shape of the paint surface of the vehicle body, select a suitable elliptical cover 7 to ensure that the cover mouth of the elliptical cover 7 can cover the minimally invasive position; adjust the direction and flow of spraying through the first adjustment head 3 and the second adjustment head 4 to ensure that the touch-up paint material can be accurately sprayed to the minimally invasive position. At this time, the transparent cover 8 can be observed to ensure that the touch-up paint position of the nozzle and the minimally invasive paint surface is clearly visible; start the spray gun body 1, and the material is sprayed out from the nozzle, which is restricted by the elliptical cover 7 to ensure that the touch-up paint material can be accurately sprayed to the minimally invasive position. At the same time, connect the soft cover 9 and the petal-shaped soft cover 10 to the car body to ensure that the touch-up paint material can be evenly distributed in the minimally invasive position; during the spraying process, excess touch-up paint material will be absorbed by the liquid-absorbing sponge 11 in the petal-shaped soft cover 10 to prevent dripping or flowing on the paint surface.

[0025] When the petal-shaped soft cover 10 is close to the car body, each of its petals will be in close contact with the surface of the car body. At this time, the liquid-absorbing sponge 11 in the petals will also be closely attached to the car body; during the spraying process, the excess paint-repairing materials will contact the petals of the petal-shaped soft cover 10 and the liquid-absorbing sponge 11. Since the liquid-absorbing sponge 11 has good liquid absorption performance, it can quickly absorb these excess paint-repairing materials; since each petal of the petal-shaped soft cover 10 is provided with a slit 12, these slits 12 can evenly distribute the paint-repairing materials absorbed by the liquid-absorbing sponge 11 to the minimally invasive position of the car body, making the paint surface smoother and more uniform. The minimally invasive paint-repairing dot spraying device for the car body paint surface can realize the precise spraying of the car body paint surface, while avoiding dripping or flowing of the paint surface, thereby improving the paint-repairing effect and quality.
