Description

Technical Field

[0001] This utility model relates to the field of automotive lamp coating technology, specifically to a nano-coating atomization device for automotive lamp coating. Background Technology

[0002] After injection molding, the transparent lens cover of the car headlight needs to be coated with a siliconized coating to improve the surface hardness of the lens cover, significantly enhance its wear resistance and scratch resistance. The siliconization process is not sensitive to ultraviolet rays, which can effectively resist ultraviolet corrosion and prevent the lens cover from aging and yellowing due to long-term exposure to light.

[0003] In related technologies, ultrasonic nozzles are typically used to atomize liquid silicon compounds into micron-sized droplets through high-frequency vibration, which are then sprayed onto the lamp cover surface. However, lamp covers come in various shapes, with most automotive lights being irregularly curved. To ensure sufficient spraying coverage for the ultrasonic nozzle, the distance between the nozzle and the lamp cover needs to be controlled. This distance causes the micron-sized droplets to easily splash into the surrounding environment as they fly towards the lamp cover, resulting in material waste and affecting the lamp cover spraying efficiency to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a nano-coating atomization device for automotive headlight coating, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nano-coating atomization device for automotive headlight coating, comprising a material tank, wherein the upper surface of the material tank is provided with an ultrasonic disperser, a pressure relief pipe, and an air inlet; the ultrasonic disperser improves the uniformity of material mixing and enhances the dispersion stability of the material, thereby ensuring the stability of the headlight coating effect;

[0006] A liquid pump is installed on the side of the material tank and connected to the material tank. The outlet of the liquid pump is connected to an ultrasonic nozzle, which enables rapid atomization of the material and facilitates uniform spraying of the vehicle lights.

[0007] A double-layered cylinder is screwed to an ultrasonic nozzle. The lower surface of the double-layered cylinder is provided with several trapezoidal nozzles arranged in a ring. The airflow restricts the direction of material ejection, thereby reducing material waste.

[0008] Furthermore, an electrically controlled feeding valve and an electrically controlled discharging valve are installed on the upper surface of the material tank. The liquid pump is connected to the electrically controlled discharging valve. A level gauge is installed on the upper surface of the material tank. The level gauge detects the liquid level of the material in the material tank and opens the electrically controlled feeding valve to achieve automatic feeding.

[0009] Furthermore, a filter head is installed on the pressure relief pipe. The filter head includes a connecting plate with air holes. A filter element is provided on the surface of the connecting plate, and a dust cover is fitted onto the connecting plate. The filter element can prevent impurities from falling into the material tank, ensuring the purity of the material and a cleaner coating for the vehicle lights.

[0010] Furthermore, the double-layered cylinder is connected to a horn cover, the inside of which has an arc surface to guide airflow and facilitate the full application of material to the headlights.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) After the liquid pump draws the material, it is sent to the ultrasonic nozzle. The ultrasonic nozzle atomizes the material and sprays it out. The air inlet provides compressed air to the double-layer cylinder. The compressed air is sprayed out from the trapezoidal nozzle to form an annular air curtain. The airflow is used to carry the material spray to the surface of the car headlight, reducing the dispersion of the material and improving the efficiency of the headlight cover spraying.

[0013] (2) When the liquid pump draws out the material, clean gas is introduced through the air inlet to maintain the air pressure balance of the material tank. Excess gas is discharged from the filter element. The filter element blocks impurities from entering the material tank. The ultrasonic disperser promotes the uniform dispersion of the material and maintains the purity and uniformity of the material.

[0014] (3) The level gauge detects the liquid level in the material tank. When the liquid level is lower than the threshold, the electric control feeding valve opens automatically to automatically replenish the material. No manual operation is required, and the degree of automation is high. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 This utility model provides a technical solution: a nano-coating atomizing device for automotive headlight coating, including a material tank 1. The upper surface of the material tank 1 is provided with an ultrasonic disperser 5, a pressure relief pipe 18, and an air inlet 2. The ultrasonic disperser 5 can maintain the flow state of the material through the cavitation effect of ultrasound and mechanical vibration, promote the uniformity of the material, and prevent sedimentation problems. When the liquid pump 10 draws the material, the air inlet 2 sends pure gas into the material tank 1 to ensure that the liquid pump 10 draws the material smoothly. The gas is discharged from the pressure relief pipe 18 to prevent the material tank 1 from expanding and being damaged.

[0023] A liquid pump 10 is installed on the side of the material tank 1 and communicates with the material tank 1. The outlet of the liquid pump 10 is connected to an ultrasonic nozzle 9. The liquid pump 10 can quickly and stably transport the material in the material tank 1 to the ultrasonic nozzle 9 to ensure a continuous supply of material. The ultrasonic nozzle 9 atomizes the liquid material into micron-sized droplets through high-frequency vibration. The atomized particles are evenly distributed to ensure uniform coating on the surface of the vehicle headlight.

[0024] The double-layer cylinder 12 is screwed to the ultrasonic nozzle 9. The lower surface of the double-layer cylinder 12 is provided with a number of trapezoidal nozzles 14 arranged in a ring. The trapezoidal nozzles 14 cause air to be ejected in a trapezoidal shape. The number of trapezoidal nozzles 14 forms an annular air curtain. The air curtain can limit the dispersion of materials and reduce material waste.

[0025] In this embodiment, as Figure 1 As shown, an electrically controlled feeding valve 6 and an electrically controlled discharging valve 7 are installed on the upper surface of the material tank 1. The liquid pump 10 is connected to the electrically controlled discharging valve 7, and the material replenishment pipe is connected to the electrically controlled feeding valve 6. A liquid level gauge 4 is installed on the upper surface of the material tank 1. When the liquid level gauge 4 detects that the material liquid level is lower than the set threshold, the electrically controlled feeding valve 6 opens to realize the automatic replenishment of material. When the material liquid level reaches the preset height, the electrically controlled feeding valve 6 closes.

[0026] In this embodiment, a filter head is installed on the pressure relief pipe 18. The filter head blocks impurities from entering the material tank 1. Impurities falling onto the filter head are blocked by the filter head, ensuring the purity of the material and maintaining the yield of the vehicle headlight spraying.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, the filter head includes a connecting plate 15 with vents 17. The connecting plate 15 is connected to a pressure relief pipe 18. Gas entering the dust cover 3 is discharged through the vents 17 to ensure the balance of air pressure inside the material tank 1. A filter element 16 is provided on the surface of the connecting plate 15. The dust cover 3 is fitted onto the connecting plate 15. Impurities entering the dust cover 3 are blocked by the filter element 16, effectively preventing impurities from entering the material tank 1 through the pressure relief pipe 18.

[0028] In this embodiment, as Figure 2 As shown, the double-layer cylinder 12 is connected to a horn cover 8. The horn cover 8 has an arc surface 11 inside. The arc surface 11 guides the direction of air flow, avoids large-scale air flow, and can limit the scattering of materials.

[0029] In this embodiment, as Figure 2 As shown, the double-layer cylinder 12 is connected to an air inlet 13. Compressed air enters the double-layer cylinder 12 through the air inlet 13. By controlling the pressure of the compressed air, the spraying range can be changed.

[0030] Specifically, during use, pure gas enters the material tank 1 through the air inlet 2. When the pressure in the material tank 1 increases, the excess gas is discharged from the pressure relief pipe 18 to ensure that the material tank 1 does not expand excessively. The ultrasonic disperser 5 generates a uniform physical vibration field in the material to maintain the uniformity of the material.

[0031] After the electronically controlled discharge valve 7 is opened, the liquid pump 10 draws in the material and delivers it to the ultrasonic nozzle 9. The ultrasonic nozzle 9 atomizes the material and sprays it onto the horn cover 8. Compressed air enters the double-layer cylinder 12 through the air inlet 13. Several trapezoidal nozzles 14 arranged in a ring on the double-layer cylinder 12 make the air form a ring-shaped air curtain, preventing the material from escaping everywhere. By using the air to increase the energy of the material, it ensures that the material is sprayed onto the headlights more accurately and quickly, reducing material waste and improving spraying efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
