Abstract
Description
Technical Field
[0001] The utility model belongs to the field of spraying equipment, in particular to a target material spraying device with a cold spraying structure. Background Art
[0002] A target spraying device is a device used to apply a coating to the surface of a target material. Current target spraying devices have several drawbacks. First, methods like thermal spraying can easily overheat the material during the heating process. This is due to the high and difficult-to-precise control of the heating source temperature, which can lead to changes in material properties. For example, some alloys may experience grain growth and phase transformation, affecting the target's performance. The conventional approach to this problem is to optimize the heating parameters, but achieving complete precision is difficult, and variations between batches of material can also cause fluctuations in results. Second, coating uniformity is poor due to factors such as inadequate control of the relative motion between the spray gun and the target and unstable gas flow fields. Improved motion control systems and optimized spray gun design are commonly used to improve this, but ensuring uniformity remains difficult for complex target shapes, and these improvements are costly. Therefore, a new structure is needed to address these technical issues. Utility Model Content

The nozzle component 320 is connected to the high-pressure gas component 220 through a hose.
[0020] See also Figures 1 to 2 As a first embodiment of the present invention, a powder storage tank 100 is provided with spray powder inside, a delivery pipe 120 is installed on the outer surface of the powder storage tank 100, an inlet end of the delivery pipe 120 is provided at the bottom inside the powder storage tank 100, an end of the delivery pipe 120 away from the powder storage tank 100 is connected to the inlet of a pump 210, and an outlet of the pump 210 is connected to the inlet of a high-pressure gas component 220 through a pipeline;
[0021] A hose is installed at the outlet of the high-pressure gas component 220. A control box 230 and a spraying platform 240 are installed on the left edge of the upper surface of the chassis 200. The control box 230 is electrically connected to the pump 210, the high-pressure gas component 220, and the operating components through wires.
[0022] During use, if the user needs to spray the target material, first place the target material on the upper surface of the spraying platform 240. After the target material is placed, the user can start the pump 210 and the high-pressure gas component 220, so that the pump 210 extracts the spray powder inside the powder storage tank 100 into the high-pressure gas component 220 through the delivery pipe 120, and then the high-pressure gas component 220 conveys the powder in the form of ultra-high-pressure airflow through the hose to the nozzle component 320, and then the nozzle component 320 sprays the airflow containing the spray powder on the surface of the target material in a high-pressure and high-speed state, thereby completing the spraying of the target material. After the spraying of one side of the target material is completed, turn the target material over and perform the same operation according to the above steps. (In order to make the powder obtain sufficient kinetic energy, the high-pressure gas component 220 needs to provide high-pressure gas, and accurately Regulating the gas flow, including a gas compressor, a pressure regulating valve and a flow regulating valve. The pressure regulating valve can adjust the gas pressure to an appropriate range (generally 1-5 MPa, depending on the powder material and spraying requirements), and the flow regulating valve controls the gas flow entering the nozzle 330 to ensure that the powder can be uniformly accelerated. Its specific structure and working principle are not described here. During use, the spraying component is combined with the operating component to achieve cold spraying. During the cold spraying process, the powder particles mainly rely on the kinetic energy of high-speed particles to be deposited on the surface of the target material. The particle temperature will not be heated to above the melting point of the material before impact. Thermal spraying may change the crystal structure or electrical properties of the material, while cold spraying can avoid such thermal damage, ensuring that the original performance of the material is not affected, thereby maintaining the good performance of the target material in electronic equipment.
[0023] See also Figures 1 to 2 As a second embodiment of the present invention, two chute grooves 300 are symmetrically formed on the upper surface of the spraying platform 240.

[0025] The nozzle 330 inside the nozzle member 320 is a Laval nozzle 330;
[0026] During use, when the target material is placed on the upper surface of the spraying platform 240, the user can start the screw motor 1 inside the slide 300 on the upper surface of the spraying platform 240 and the screw motor 2 inside the gantry 310 through the control box 230. When the screw motor 1 is running, the nozzle part 320 can be operated on the Y axis through the gantry 310. When the screw motor 2 inside the gantry 310 is running, the nozzle part 320 can be operated on the X axis. When the two are running at the same time, a cross-shaped operation structure is formed, so that the nozzle part 320 can better adapt to the structure of the target material, and the nozzle 330 used inside the nozzle part 320 is a Laval nozzle 330 (the Laval nozzle 330 has a convergent-divergent shape. The gas reaches the speed of sound when passing through the throat, and then further accelerates to supersonic speed in the expansion section, thereby achieving a better spraying effect. , its specific structure and principle are not described in detail here), when the nozzle component 320 transports the spraying powder to the inside of the nozzle 330 through the operating steps of the first embodiment and then sprays it out from the nozzle 330, a better spraying effect can be achieved. Due to the slidable installation method of the gantry 310 and the nozzle component 320 during use, the device can flexibly adapt to targets of various shapes and sizes. For targets of smaller sizes, the movement range of the nozzle component 320 can be adjusted to allow it to be sprayed in a suitable area, avoiding powder waste and uneven coating thickness. For targets with irregular shapes, such as targets with curved surfaces or complex geometric shapes, the movement trajectory of the nozzle component 320 can be precisely controlled to enable the nozzle to always maintain a suitable distance and angle from the target surface, ensuring that the powder particles can be effectively deposited on the target surface, thereby improving the coating quality.
