Description

Technical Field

[0001] The invention relates to the technical field of aluminum product surface processing, in particular to an aluminum product surface processing device. Background Art

[0002] In the surface processing of aluminum products, the application of electrostatic spraying equipment is very extensive. It is suitable for the surface treatment of various aluminum products, such as aluminum profiles, aluminum plates, aluminum home appliances and electronic product shells, etc. Through electrostatic spraying, aluminum products can be given a good appearance and protective performance to meet the needs of different industries and products.

[0003] An electrostatic spraying device disclosed in Chinese patent publication number CN115318519B utilizes a nozzle to diffuse paint so that charged paint particles are attracted to the surface of a workpiece with an opposite charge under the action of an electrostatic field.

[0004] However, compared with the existing technologies in the related fields, the diameter of the diffusion nozzle of the existing spray gun is usually fixed, and the diffusion range of the paint is fixed. Therefore, it cannot be adaptively adjusted according to the spraying requirements, resulting in poor effect when spraying workpieces of different shapes and sizes, and when spraying corners or depressions, uneven spraying or paint waste is prone to occur. Therefore, for workpieces with complex shapes, multiple spraying is required to achieve the ideal coverage effect, which increases the spraying time and cost. Multiple spraying will also result in problems such as uneven spraying and inconsistent coating thickness, which can easily lead to product defects and increase the rework rate. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide an aluminum product surface processing device.

When the trigger is slightly pulled, the discharge pressure becomes smaller, and the impact force received by the multiple diffusion components will also become smaller. At this time, the elastic force of the elastic component is greater than the impact force received by the multiple diffusion components, and then the elastic component drives the multiple diffusion components to slide to one side of the gun body, and then the guide component is used to reduce the tilting amplitude of the multiple diffusion components, so that the electrostatic paint can be diffused over a small range.

[0007] Furthermore, the diffusion assembly includes a main frame, and a first baffle and a second baffle are fixedly disposed on both sides of the main frame.

[0008] Furthermore, the first baffles and the second baffles are arranged alternately up and down, and by using the first baffles and the second baffles to be arranged alternately up and down, when the tilting amplitude of the multiple diffusion components becomes smaller, the multiple baffles can overlap each other.

[0009] Furthermore, the elastic component includes a mounting groove provided inside the fixing member, a movable disk is slidably provided inside the mounting groove, and the movable disk is cooperatively connected with the mounting groove through an elastic member.

[0010] Furthermore, an articulated frame is fixedly provided at one end of the main frame close to the movable disk, a hinged component is fixedly provided on the outer surface of the movable disk, and the hinged component and the articulated frame are connected by a rotating shaft.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0022] An embodiment of an aluminum product surface processing device of the present invention is as follows Figures 1 to 8 As shown, it includes a gun body 1, a fixing part 2 is provided at the muzzle of the gun body 1, a plurality of diffusion components 3 for controlling the distribution of the paint are provided on the outer surface of the fixing part 2 away from the end of the gun body 1, an elastic component 4 is provided inside the fixing part 2, the plurality of diffusion components 3 are hinged to the elastic component 4, a guide component 5 is provided at one end of the fixing part 2 corresponding to the plurality of diffusion components 3 that are tilted up, and a trigger 101 for controlling the discharge pressure is provided on the gun body 1.

[0023] like Figures 1 to 7 As shown, when the trigger 101 is pulled hard, the discharge pressure increases, and the impact force on the multiple diffusion components 3 will also increase accordingly. At this time, the elastic force of the elastic component 4 is smaller than the impact force on the multiple diffusion components 3, and then the multiple diffusion components 3 drive the elastic component 4 to slide to the side away from the gun body 1, and then the guide component 5 is used to increase the tilting amplitude of the multiple diffusion components 3, so that the electrostatic paint can be diffused over a large range. When the trigger 101 is pulled lightly, the discharge pressure becomes smaller, and the impact force on the multiple diffusion components 3 will also become smaller. At this time, the elastic force of the elastic component 4 is greater than the impact force on the multiple diffusion components 3, and then the elastic component 4 drives the multiple diffusion components 3 to slide to one side of the gun body 1, and then the guide component 5 is used to reduce the tilting amplitude of the multiple diffusion components 3, so that the electrostatic paint can be diffused over a small range.

[0024] like Figure 1 and Figure 2 As shown, the interior of the gun body 1 is provided with an electrode member 102 for discharging, and the electrode member 102 is electrically connected to the fixing member 2. The gun body 1 is provided with a coating interface 103, an airflow interface 104 and a power supply interface 105. The electrode member 102 inside the gun body 1 is powered through the power supply interface 105, and then the inside of the gun body 1 is supplied with air through the airflow interface 104, and then the inside of the gun body 1 is supplied with material through the coating interface 103. At this time, the surface of the aluminum product can be electrostatically sprayed. The specific principle is that the electrode member 102 and the fixing member 2 are connected to the negative electrode, and the workpiece is connected to the positive electrode and grounded, as shown in FIG. Figure 3 , Figure 4 and Figure 6 As shown, the paint is sprayed through multiple diffusion components 3, and the atomized paint particles are negatively charged due to contact when leaving the spray gun 1. These charged paint particles are attracted to move toward the workpiece surface connected to the positive electrode under the action of the electric field force. The negatively charged paint particles move toward the workpiece surface with positive polarity under the action of the electrostatic field and are evenly deposited on the workpiece surface to form a uniform coating film. After electrostatic spraying, the workpiece usually undergoes a baking and curing process to cause the resin and other components in the coating film to undergo a chemical reaction, thereby forming a strong and durable coating.

[0025] like Figure 3 , Figure 4 and Figure 6 As shown, the diffusion component 3 includes a main frame 301, and the first baffle 302 and the second baffle 303 are fixed on both sides of the main frame 301. The first baffle 302 and the second baffle 303 are staggered up and down. The grooves with different heights (the first baffle 302 and the second baffle 303 are staggered up and down) help to better control the flow and dispersion of the paint, so that the paint forms a more uniform atomization effect when sprayed. This design helps to improve the uniformity and quality of the coating. By staggering the first baffle 302 and the second baffle 303 up and down, the multiple diffusion components 3 can be tilted smaller, and the multiple baffles can be overlapped with each other; as shown in FIG. Figure 6 and Figure 7 As shown, the elastic component 4 includes a mounting groove 401 opened inside the fixing member 2, and a movable plate 402 is slidably provided inside the mounting groove 401. The movable plate 402 is connected to the mounting groove 401 through an elastic member 403; Figure 7 As shown, a hinge frame 3011 is fixedly provided at one end of the main frame 301 close to the movable disk 402, and a hinge 4021 is fixedly provided on the outer surface of the movable disk 402. The hinge 4021 is connected to the hinge frame 3011 through a rotating shaft; Figure 6 and Figure 7As shown, the guide assembly 5 includes a receiving groove 501 opened on the fixing member 2, a support rod 502 is fixedly provided on one side of the main frame 301 close to the receiving groove 501, and two guide shafts 503 are symmetrically fixedly provided on one end of the support rod 502 away from the main frame 301, and guide grooves 504 are opened at positions of the fixing member 2 corresponding to the two guide shafts 503; Figure 7 and Figure 8 As shown, the plurality of guide grooves 504 are all inclined toward the direction of the gun body 1, and the ends of the guide shafts 503 are each provided with balls 5031. The provided balls 5031 can reduce the friction between the guide shafts 503 and the guide grooves 504, thereby improving the stability of the guide shafts 503 during operation.

[0026] Combined with the above structure: Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, when the trigger 101 is pulled hard, the discharge pressure increases, and the impact force on the multiple diffusion components 3 will also increase accordingly. At this time, the elastic force of the elastic component 4 is less than the impact force on the multiple diffusion components 3, and then the multiple diffusion components 3 drive the elastic component 4 to slide to the side away from the gun body 1, and then the guide component 5 is used to increase the tilting amplitude of the multiple diffusion components 3 (when the impact force on the multiple diffusion components 3 increases, the multiple diffusion components 3 drive the movable disk 402 to compress the elastic component 403 through the hinge frame 3011 and the hinge 4021, and slide to the side away from the gun body 1. At this time, the cooperation between the guide shaft 503 and the guide groove 504 (the multiple guide grooves 504 are all inclined toward the direction of the gun body 1) is used to increase the tilting amplitude of the multiple diffusion components 3). When the tilting amplitude of the multiple diffusion components 3 becomes larger, the electrostatic paint can be diffused over a large range, so that the paint can be quickly coated on the surface of the aluminum product, thereby reducing the waste of paint and improving the processing efficiency; as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when the trigger 101 is slightly pulled, the discharge pressure becomes smaller, and the impact force on the multiple diffusion components 3 will also become smaller. At this time, the elastic force of the elastic component 4 is greater than the impact force on the multiple diffusion components 3, and then the elastic component 4 drives the multiple diffusion components 3 to slide to one side of the gun body 1 (when the impact force on the multiple diffusion components 3 becomes smaller, the elastic force of the elastic member 403 is restored, so that the movable disk 402 drives the multiple diffusion components 3 to slide to one side of the gun body 1 through the hinge frame 3011 and the hinge 4021. At this time, the cooperation between the guide shaft 503 and the guide groove 504 (the multiple guide grooves 504 are all inclined toward the direction of the gun body 1) is used to reduce the tilting amplitude of the multiple diffusion components 3). When the tilting amplitude of the multiple diffusion components 3 becomes smaller, the electrostatic paint can be diffused in a small range, so that the paint can be accurately applied to the corners or surface depressions of aluminum products, effectively reducing the waste of paint, and there is no need to spray the corners or surface depressions of aluminum products multiple times.

[0027] To sum up, the specific effects are as follows: First, through the adaptive adjustment of the diffusion component 3, when it is necessary to spray the corners or surface depressions of aluminum products, the discharge pressure can be reduced to achieve a small range of diffusion of the paint, ensuring that the paint can be accurately coated on the target area, avoiding the problem of uneven spraying or omissions; second, because the diffusion component 3 can automatically adjust the tilting amplitude according to the spraying requirements, unnecessary paint diffusion is reduced, thereby significantly reducing the waste of paint, especially when spraying corners or depressions, precise spraying reduces the use of excess paint; third, through the simple trigger 101 control, the staff can easily adjust the spraying pressure and diffusion range as needed, without complicated operating steps, and can automatically adjust the spraying parameters according to different spraying requirements (small range or large range), with stronger adaptability, suitable for a variety of aluminum products of different shapes and sizes, and improve the versatility and flexibility of the equipment, thereby further improving work efficiency and reducing labor intensity due to the improvement of spraying accuracy and efficiency.

[0028] like Figure 6 and Figure 7 As shown, a slide groove 201 is provided at the position of the fixing member 2 corresponding to the hinge 4021, and a shielding member 4022 is fixedly provided at the position of the hinge 4021 corresponding to the slide groove 201. The shielding member 4022 can be used to shield the slide groove 201 to prevent paint from entering the installation groove 401 from the slide groove 201.

[0029] The working process is as follows: S1, such as Figure 1 and Figure 2As shown, the electrode member 102 inside the gun body 1 is powered through the power supply interface 105, and then the inside of the gun body 1 is supplied with air through the air flow interface 104, and then the inside of the gun body 1 is supplied with material through the coating interface 103, and now the surface of the aluminum product can be electrostatically sprayed; S2, such as Figure 1 As shown, when a large area of ​​the aluminum product surface needs to be sprayed, the worker pulls the trigger 101 of the gun body 1 vigorously; S3, such as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, when the trigger 101 is pulled hard, the discharge pressure increases, and the impact force on the multiple diffusion components 3 also increases accordingly. At this time, the elastic force of the elastic component 4 is smaller than the impact force on the multiple diffusion components 3, and then the multiple diffusion components 3 drive the elastic component 4 to slide to the side away from the gun body 1, and then the guide component 5 increases the tilting amplitude of the multiple diffusion components 3; S4, such as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the detailed process of step S3 is that when the impact force on the multiple diffusion components 3 increases, the multiple diffusion components 3 drive the movable plate 402 to compress the elastic component 403 through the hinge frame 3011 and the hinge 4021, and slide to the side away from the gun body 1. At this time, the cooperation between the guide shaft 503 and the guide groove 504 (the multiple guide grooves 504 are all inclined toward the direction of the gun body 1) is used to increase the tilting amplitude of the multiple diffusion components 3; S5, such as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, when the tilting amplitude of the plurality of diffusion components 3 becomes larger, the electrostatic paint can be diffused over a large range, so that the paint can be quickly coated on the surface of the aluminum product, thereby reducing the waste of paint and improving the processing efficiency; S6, such as Figure 1 As shown, when it is necessary to spray the corners or concave areas of the surface of the aluminum product, the worker slightly pulls the trigger 101 of the gun body 1; S7, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when the trigger 101 is slightly pulled, the discharge pressure becomes smaller, and the impact force on the multiple diffusion components 3 also becomes smaller. At this time, the elastic force of the elastic component 4 is greater than the impact force on the multiple diffusion components 3, and then the elastic component 4 drives the multiple diffusion components 3 to slide to one side of the gun body 1; S8, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the detailed process of step S7 is that when the impact force on the multiple diffusion components 3 becomes smaller, the elastic force of the elastic member 403 is restored, so that the movable plate 402 drives the multiple diffusion components 3 to slide toward one side of the gun body 1 through the hinge frame 3011 and the hinge 4021. At this time, the cooperation between the guide shaft 503 and the guide groove 504 (the multiple guide grooves 504 are all inclined toward the direction of the gun body 1) is used to reduce the tilting amplitude of the multiple diffusion components 3; S9, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when the tilting amplitude of the multiple diffusion components 3 becomes smaller, the electrostatic paint can be diffused in a small range, so that the paint can be accurately applied to the corners or surface depressions of the aluminum product, effectively reducing the waste of paint and eliminating the need for multiple spraying of the corners or surface depressions of the aluminum product.
