Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic component coating technology, in particular to a cold spraying equipment for electronic component coating. BACKGROUND

[0002] The cold spraying equipment refers to an equipment for coating the surface of an electronic component by using cold spraying technology. The cold spraying technology is a high-speed airflow impact spraying technology. The coating material is sprayed onto the surface of the coated workpiece at supersonic speed to provide corrosion resistance, wear resistance, electrical conductivity or insulation, etc. of the electronic component to protect the component and improve its function.

[0003] During the cold spraying process, the high-speed sprayed powder particles form multiple protruding particle layers on the surface of the substrate. Therefore, the coating surface obtained by cold spraying has high roughness. When the cold sprayed particles are accumulated, pores are formed between the particles due to incomplete bonding, which reduces the compactness and sealing of the coating, making it more susceptible to moisture, corrosion, etc. and weakening the protective effect of the coating.

[0004] In addition, during the cold spraying process of the electronic component, the liquid or solid material is sprayed onto the surface at high speed to form a coating. At the same time, the liquid or solid material sprayed by the cold spraying equipment is carried away by the high-speed airflow or vortex generated by the spraying nozzle during the spraying process to form dust, which accumulates inside the equipment. Not only does this cause a waste of resources, but the dust formed will also adhere to the surface of the workpiece or the parts of the equipment if not promptly treated, affecting the normal use of the workpiece and the cold spraying equipment.

[0005] Therefore, we propose a cold spraying equipment for electronic component coating that has uniform particle layers on the surface of the workpiece, collects dust, and prevents the collection mechanism from being clogged. SUMMARY

[0046] Further embodiments

[0047] Please see Figure 2 as well as Figure 9 As shown, a cold spraying device for coating electronic components includes a knock-off mechanism comprising a second fixing block 5, which is fixedly connected to the side wall of a protective cover 2. A second connecting rod 501 is rotatably connected to the opposite face of the second fixing block 5. A drive rod 502 is rotatably connected to both sides of the second connecting rod 501 near the second fixing block 5. The end of the drive rod 502 away from the second connecting rod 501 is fixedly connected to the top of a vibrating plate 309. A counterweight ball 503 is fixedly connected to the end of the second connecting rod 501 away from the drive rod 502. The second fixing block 5 is located on the side wall of the protective cover 2 above the vacuum pump 405.

[0048] The effects achieved by the above embodiments are as follows: when the counterweight ball 503 intermittently strikes the clamping plate 6, the clamping plate 6 uses the vibration generated by the strike to promote the removal of adhering particles generated by the spraying on the outer surface of the electronic component, and improve the fluidity of the coating on the surface of the electronic component. The sprayed coating can better penetrate and cover the entire outer surface of the electronic component, making the coating more uniform. Striking the clamping plate 6 can help remove air bubbles and voids in the coating material, prevent air bubbles from being trapped in the coating, and ensure the density and uniformity of the coating.

[0049] The working principle of the present application:

[0050] Initial state: the external drive of the drive shaft 301 is in the unstarted state, the telescopic spring 310 is in the state of being affected only by the downward gravity of the shock plate 309, and the inner cavity of the collection box 406 is in the vacant state. Before starting the device, the electronic components are placed on the clamping plate 6 for clamping and fixing.

[0051] In use: start the external control, the external control will promote the rotation of the drive shaft 301, when the drive shaft 301 rotates, the eccentric disc 302 fixedly connected to the opposite side of the drive shaft 301 will rotate together, because the eccentric disc 302 is rotatably connected to the end of the drive shaft 301 away from the drive disc one 305, so when the drive shaft 301 promotes the rotation of the eccentric disc 302, the connecting rod one 305 rotatably connected between the opposite sides of the eccentric disc 302 will follow the eccentric disc 302 to make a circular motion, further, because the fixed block one 306 is rotatably connected to the end of the connecting rod one 305 away from the connecting rod one 305, and the sliding block 307 is slidably connected in the limiting cylinder one 303, so when the connecting rod one 305 makes a circular motion, it will pull the sliding block 307 to slide up and down on the inner cavity wall of the limiting cylinder one 303, further, because the two limiting cylinder two 304 inner cavities fixedly connected to the top of the fixed table 3 are both fixedly connected with the extension spring 310, and the extension spring 310 is fixedly connected to the vibration plate 309 at the end away from the bottom of the limiting cylinder two 304, and the vibration plate 309 is fixedly connected to the fixed cylinder 308 at the bottom, and the fixed cylinder 308 is fixedly connected to the fixed rod 311 at the bottom, so when the sliding block 307 slides in the limiting cylinder one 303, it will impact the fixed rod 311 to produce vibration, which is transmitted to the extension spring 310 through the vibration plate 309, and when external force acts on the extension spring 310, the extension spring 310 is compressed or extruded, when compressed, the extension spring 310 will store energy, so that the extension spring 310 has the characteristics of resilience, at this time, the vibration plate 309 slidably connected to the inner cavity wall of the base 1 is constantly vibrating due to the up and down elastic force of the extension spring 310, which drives the electronic components on the clamping plate 6 to vibrate together, vibration can help the uniform distribution of granular coating on the surface of electronic components, reduce the thickness variation and unevenness of the coating, ensure the uniform quality and performance of the coating, through continuous vibration, the contact between coating particles and the surface of electronic components is more closely, which increases the physical adsorption force or chemical bonding force between the coating and the substrate, improves the adhesion of the coating, helps to prevent the peeling or falling off of the coating, vibration promotes the close arrangement and filling between particles, further increases the compactness and firmness of the coating, helps to block potential damage factors such as wear, corrosion or environmental conditions, vibration can effectively eliminate coating defects such as particle accumulation, bubbles or voids, improve the quality and appearance of the coating, ensure the uniformity and neatness of the workpiece surface, and uniform vibration of the uneven granular coating on the surface can improve production efficiency, uniform coating distribution reduces the number of spraying or processing time in subsequent processing steps, saves production cost and improves work efficiency;

[0052] Further, when the vibration plate 309 slides up and down on the inner cavity wall of the base 1, the piston cylinder 4 fixedly connected to the vibration plate 309 also moves up and down together with the vibration plate 309. Because the piston rod 404 is fixedly connected to the inner cavity bottom of the limiting cylinder two 304, and the piston head 403 is fixedly connected to the end of the piston rod 404 away from the limiting cylinder two 304, and the piston head 403 slides on the inner cavity wall of the piston cylinder 4, therefore, when the piston cylinder 4 moves up and down, the piston rod 404 will drive the piston head 403 to slide up and down on the inner cavity wall of the piston cylinder 4. When the piston rod 404 drives the piston head 403 to slide down on the inner cavity wall of the piston cylinder 4, the one-way air inlet valve 402 will suck in the external gas. When the piston rod 404 drives the piston head 403 to slide up on the inner cavity wall of the piston cylinder 4, the one-way air outlet valve 401 will discharge the gas in the piston cylinder 4. The discharged gas blows the dust generated in the cold spraying process to one side of the start-up air extractor 405. At this time, the air extractor 405 sucks the dust generated in the cold spraying process from the inner cavity of the protective cover 2 into the collection box 406. The dust generated in the coating process contains harmful substances or particulate matter. When the dust scatters in the surrounding environment, it will pollute the air. By uniformly accumulating and collecting the dust, the spread of the dust can be effectively prevented, and the risk of environmental pollution can be reduced. By uniformly accumulating and collecting the dust, the subsequent cleaning work can be simplified. Cleaning the scattered dust may require more time. By centralized collection, the dust can be treated centrally, improving the cleaning efficiency and ensuring thorough cleaning. Part of the dust contains the coating layer for recycling. After appropriate treatment and separation, it can be recycled or reused, reducing production costs.

[0053] Further, when the vibration plate 309 slides up and down on the inner cavity wall of the base 1, the drive rod 502 fixedly connected to the top of the vibration plate 309 will move up and down together with the vibration plate 309. Because the fixed block two 5 is rotatably connected to the connecting rod two 501 on the opposite side, and the connecting rod two 501 is rotatably connected to the drive rod 502 near the fixed plate two one end, therefore, when the drive rod 502 moves up and down, the connecting rod two 501 away from the vibration plate 309 will be driven by the drive rod 502 to rotate between the fixed block two 5. Because the counterweight ball 503 is fixedly connected to the end of the connecting rod two 501 away from the drive rod 502, and the drive rod 502 drives the connecting rod two 501 to rotate between the fixed block two 5, therefore, the counterweight ball 503 will gradually approach the clamping plate 6 and hit the upper surface of the clamping plate 6. By knocking the clamping plate 6, the coating on the electronic components on the clamping plate 6 can be made more uniform. By knocking the clamping plate that holds the electronic components, the coating material can be evenly distributed on the surface of the electronic components, avoiding uneven thickness, local over-thickness or under-thickness of the coating, thereby improving the quality and consistency of the coating. Knocking the clamping plate can help the coating material better contact the surface of the electronic components and enhance the physical bonding force between them, which helps to improve the adhesion of the coating and reduce the risk of falling off, ensuring the stability and durability of the coating during use.

[0054] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
