Description

Technical Field

[0001] This utility model relates to the field of notebook shell spraying technology, and more specifically, to a carbon fiber component surface spraying device. Background Technology

[0002] With the accelerating trend towards thinner and lighter laptops, carbon fiber composite materials are widely used in casing manufacturing due to their superior properties such as high strength and lightweight. Traditional surface treatment of carbon fiber components mainly employs spraying processes, applying specialized coatings (such as polyurethane or UV paint) to the substrate surface to achieve aesthetic decoration, scratch resistance, and corrosion resistance. Currently, the industry commonly uses manual spraying or simple automated equipment, but this suffers from problems such as difficulty in controlling spray uniformity, insufficient edge coverage, and low curing efficiency. Especially for laptop casings with complex curved surfaces, traditional processes struggle to meet the consistent surface quality requirements of high-end products.

[0003] During the spraying process, fixed fixtures are difficult to adapt to carbon fiber shells of different sizes and curvatures, resulting in spraying dead zones; in addition, conventional single spray nozzles are difficult to effectively cover the edges of parts, easily causing uneven coating thickness. Splitting the spraying and drying processes separately is not only inefficient, but may also introduce contamination during the transfer process. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0025] Please see Figure 1-5 In this utility model, a carbon fiber component surface spraying device includes a spraying box 1 and a box door 2 installed on its front. A mounting base 3 is fixedly installed at the bottom of the spraying box 1, and an electric push rod 4 is fixedly installed at the top of the mounting base 3. A bearing component 5 is installed at the top of the electric push rod 4. A servo motor 6 is fixedly installed on the right side of the spraying box 1. The output shaft of the servo motor 6 passes through and extends into the interior of the spraying box 1. A lead screw is fixedly installed on the output shaft of the servo motor 6. A movable seat 7 is threadedly connected to the lead screw. The movable seat 7 is slidably connected to the inner wall of the spraying box 1. A spraying component 8 and a drying component 9 are provided on the movable seat 7.

[0026] The support assembly 5 includes a lifting seat 501, which is fixedly installed on the top of the electric push rod 4. Support seats 502 are slidably connected to both sides of the lifting seat 501. Evenly distributed suction cups 503 are fixedly installed on the support seats 502. Two adjusting motors 504 are fixedly installed on the inner wall of the lifting seat 501. A lead screw is fixedly installed on the output shaft of the adjusting motor 504. The support seat 502 is threadedly connected to the lead screw.

[0027] The spraying assembly 8 includes a flow distribution cavity 801, which is located inside the movable seat 7. Spray heads 802 are evenly distributed and fixedly installed on the inner bottom wall of the flow distribution cavity 801. The bottom ends of the spray heads 802 penetrate through and extend to the bottom of the movable seat 7. A liquid pump 803 connected to the inside of the flow distribution cavity 801 is fixedly installed on the left side of the movable seat 7. The liquid pump 803 is connected to the external paint storage area through a hose. The leftmost spray head 802 on the inner bottom wall of the flow distribution cavity 801 and the rightmost spray head 802 on the inner bottom wall of the flow distribution cavity 801 are relatively clustered and inclined.

[0028] The drying assembly 9 includes a diversion pipe 901, which is fixedly installed at the bottom of the movable seat 7. Evenly distributed air nozzles 902 are fixedly installed at the bottom of the diversion pipe 901, and the air nozzles 902 are connected to the interior of the diversion pipe 901. An air pump 903 connected to the diversion pipe 901 is fixedly installed on the right side of the movable seat 7. The air pump 903 is connected to an external heated air intake device through a hose. A through groove 10 is provided on the back of the spray box 1. The hoses on the liquid pump 803 and the air pump 903 are connected to external equipment through the through groove 10. Limiting posts 13 are fixedly connected to both sides of the lifting seat 501, and the bearing seat 502 is slidably connected to the limiting posts 13.

[0029] When carbon fiber parts need to be coated, the operator first opens the box door 2 and places the carbon fiber parts to be coated on the suction cup 503 of the support component 5. The suction cup 503 uses negative pressure to fix the workpiece, ensuring that the workpiece is stable and does not shift during the coating process.

[0030] During the above process, if the workpiece size is large or the adsorption position needs to be adjusted, the motor 504 can drive the lead screw 2 to make the bearing seat 502 slide along the limiting post 13, thereby adjusting the horizontal distance of the suction cup 503 to adapt to workpieces of different specifications. If the workpiece height needs to be adjusted, the electric push rod 4 can drive the lifting seat 501 to rise and fall, so that the workpiece is in the best spraying position.

[0031] After the limit is completed, the servo motor 6 starts and drives the lead screw to rotate, causing the movable seat 7 to move laterally along the inner wall of the spray box 1. The liquid pump 803 delivers the externally stored paint to the distribution chamber 801 through the hose, and then distributes it evenly to each spray head 802. The spray head 802 sprays paint downwards. The spray heads 802 on the left and right sides are at an angle, which can adjust the spray volume to cover the sides of the workpiece, ensuring uniform spraying without dead corners. At the same time, the figure is a schematic diagram. In actual use, inclined spray heads can also be added at the front and rear positions to deal with the spraying of all sides.

[0032] After the coating is completed, the air pump 903 starts and delivers the externally heated airflow to the air nozzle 902 through the splitter pipe 901. Multiple air nozzles 902 spray hot air at the same time to accelerate the curing of the coating and improve production efficiency.

[0033] After spraying and drying are completed, the servo motor 6 reverses, causing the movable seat 7 to return to its initial position, and the electric push rod 4 descends, making it easier for the operator to open the box door 2 and take out the workpiece.

[0034] In this invention, the distance between the two bearing seats 502 can be adjusted by adjusting the motor 504 driving the lead screw to adapt to workpieces of different sizes. The electric push rod 4 can adjust the height of the workpiece to the optimal spraying position. During the spraying operation, multiple spray heads 802 spray evenly. Among them, the inclined spray head 802 can accurately cover the side of the workpiece, realizing efficient and uniform carbon fiber shell spraying. At the same time, the drying component 9 is transported to the air nozzle 902 through the diversion pipe 901 for efficient drying, realizing rapid curing and significantly improving the spraying quality and production efficiency.

[0035] Please see Figure 2 The bottom of the spray box 1 has two collection slots 11, which are located on both sides of the mounting base 3. A filter screen 12 is movably installed on the top of the collection slots 11.

[0036] In this invention, the paint that flies off during the spraying process can be recovered through the collection tank 11 at the bottom of the spray box 1, reducing waste. As the paint moves downwards, it passes through the filter screen 12, thus preventing impurities from entering and affecting its recycling.

[0037] Please see Figure 1 Among them, the door 2 is equipped with transparent glass 14.

[0038] In this invention, the transparent glass 14 allows operators to observe the internal state of the spray box 1 from the outside, so as to understand the status of the equipment in a timely manner.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
