Carbon fiber encapsulation tube shell surface spraying treatment device

Abstract

This invention provides a carbon fiber encapsulation tube shell surface spraying treatment device, belonging to the field of spraying processing technology. It includes a control unit and a suction module installed at the outer end of the central groove, which automatically starts after the spraying operation is completed. This module quickly generates negative pressure in the internal groove, which rapidly sucks up residual spray material from the spraying channel inside the nozzle, preventing residual spray material from accumulating and dripping due to gravity. This design eliminates the risk of residual spray material adhering to the surface of the sprayed or unsprayed carbon fiber encapsulation tube shell from the source, effectively avoiding defects such as local bumps, color differences, and uneven coating thickness. It also solves the problem that after a single spraying operation, residue in the spraying channel inside the nozzle gradually accumulates and drips downwards due to gravity. This dripping spray material residue easily adheres to the surface of the sprayed or unsprayed tube shell, damaging the uniformity of the surface coating and causing the encapsulation tube shell to fail to meet the designed surface performance indicators, significantly increasing the product defect rate.

Description

Technical Field

[0001] This invention relates to the field of spray coating technology, and in particular to a spray coating treatment device for the surface of carbon fiber encapsulated tube shells. Background Technology

[0002] The rapid development of modern science and technology, especially aerospace technology, has placed higher demands on semiconductor packaging shells. To overcome the limitations of single material properties and obtain packaging shell products with special and good comprehensive performance, people are constantly exploring new materials. Carbon fiber materials have attracted much attention due to their excellent comprehensive properties such as good high-temperature performance, high specific strength and specific modulus, and good electrical and thermal conductivity. However, the surface of untreated carbon fiber cannot be directly brazed with metals and other materials, which limits its high-performance application range. To improve the interface performance, it can be prepared into carbon fiber reinforced metal matrix composites to achieve good dynamic contact and performance designability. In the preparation process of carbon fiber reinforced metal matrix composite packaging shells, surface spraying is one of the key processes: specific functional coatings (such as anti-corrosion coatings, conductive coatings, welding compatibility coatings, etc.) need to be sprayed on the surface of the composite material to further improve the surface performance of the packaging shell and ensure that it meets the assembly and use standards of semiconductor devices.

[0003] However, there are some shortcomings in the current design of carbon fiber encapsulation shell surface spraying devices:

[0004] First, the nozzle installation structure of existing spraying equipment is usually a single-station design, meaning that only one set of nozzles can be installed at a time. In actual processing, when it is necessary to change to different types of spray materials (such as metal coating materials with different compositions or functional coatings with different viscosities) or to achieve different spraying effects (such as different coating thicknesses or different spraying textures), the current nozzle must be removed from the equipment and a new, compatible nozzle must be installed. This removal and installation process takes a long time (usually several minutes to more than ten minutes). During this time, the spraying equipment must be stopped and wait, which not only interrupts the processing flow but also significantly reduces the overall efficiency of the spraying process, making it difficult to meet the needs of mass production.

[0005] Secondly, after the spraying device completes a single spraying operation, a certain amount of spray material will remain in the spraying channels inside the nozzle (including the feed channel, nozzle cavity, etc.). During the static process of the nozzle, these residues will gradually accumulate and drip downwards due to gravity. Since the nozzle is usually directly facing the carbon fiber encapsulation shell or above the processing station, the dripping spray material residue is very easy to adhere to the surface of the encapsulated shell that has been sprayed or is to be sprayed, which will damage the uniformity of the surface coating (such as forming local bumps, color differences, uneven coating thickness, and other defects). This will cause the encapsulated shell to fail to meet the designed surface performance indicators, significantly increasing the product defect rate and production costs. Summary of the Invention

[0006] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a carbon fiber encapsulation tube shell surface spraying treatment device that can prevent spray material from dripping onto the workpiece after the spraying process, thus affecting the uniformity of the spraying. It can simultaneously install multiple spraying units and can quickly replace them.

When it is necessary to replace the nozzle to adapt to different spray materials (such as metal coating materials of different compositions or functional coatings of different viscosities) or different spraying effects (such as different coating thicknesses or different spraying textures), simply pull the spraying module upwards to release the limit on the turntable. Rotating the turntable moves the target nozzle directly below the connection hole. Then, re-inserting the spraying module with the target nozzle resumes spraying.

[0058] This application involves creating a central groove 502 at the bottom of the turntable 501, connecting the central groove 502 to the built-in groove 5051 within each group of spray heads 505, and installing a suction module 5021 at the outer end of the central groove 502. When the spraying work is completed, the suction module 5021 can automatically operate in a timely manner, generating negative pressure in the built-in groove 5051 within an extreme time to suction out the residue in the spraying channel inside the spray head 505, preventing it from dripping downwards. The spray residue is finally discharged from the side end of the suction module 5021 under the suction action of the suction module 5021 and collected centrally.

[0059] The specific usage and function of this embodiment are as follows:

[0060] In this invention, such as Figures 1 to 10As shown, the carbon fiber encapsulation shell to be sprayed is neatly placed on the support plate 302 of the support part 3. Then, the mating block 3021 at the bottom of the support plate 302 is aligned with the slots 3012 on both sides of the rotating frame 301 and inserted, so that the grooves on both sides of the mating block 3021 are inserted and fixed with the protrusions on the inner side of the slots 3012. Next, the frame 201 of the mounting part 2 is inserted and fixed to the assembly slots 1011 at both ends of the front side of the main body 101 of the control part 1 through the insert plates 203 at both ends of the rear side. Then, the cylindrical rod at the bottom of the cover 205 is inserted into the insertion holes 204 on both sides of the upper end of the frame 201 to complete the installation of the cover 205. After that... The hydraulic cylinder 202 on the bottom side inside the frame 201 is activated. The upper end of the hydraulic cylinder 202 pushes the rotating frame 301 upward until the bearing plate 302 on the rear side of the rotating frame 301 is engaged with the inner side of the frame 201, completing the loading and positioning of the carbon fiber encapsulation tube shell. Then, the corresponding nozzle 505 is selected according to the spraying requirements. If the nozzle 505 on the current turntable 501 that is aligned with the connecting hole 4012 of the sliding frame 401 does not meet the requirements, the lifting frame 402 of the processing unit 4 is pulled upward. The lifting frame 402 slides along the side frames 4011 at both ends of the front side of the sliding frame 401, driving the spraying module 403 on the lifting frame 402. Move upwards to disengage the front end of the spraying module 403 from the top of the current nozzle 505, releasing the restriction on the turntable 501; then rotate the turntable 501 of the rotating part 5, the turntable 501 rotates around the top rod 5011 at the bottom of the sliding frame 401, moving the target nozzle 505 directly below the connecting hole 4012 at the middle position of the front side of the sliding frame 401. At this time, the slider 504 where the target nozzle 505 is located is held in the movable groove 503 on the bottom side of the turntable 501 by spring cooperation, and the side grooves 5052 on both sides of the nozzle 505 are engaged with the limiting blocks 5041 on both sides inside the slider 504; then release the lifting frame. 402, the lifting frame 402 slides down along the side frame 4011 under the action of the spring, driving the front end of the spraying module 403 to pass through the connection hole 4012 and insert into the top of the target nozzle 505, completing the selection and installation of the nozzle 505. Then, the drive component of the control unit 1 is activated, and the moving frame 1021 above the adjustment groove 102 moves along the adjustment groove 102 through the screw, driving the sliding frame 401 to move back and forth along the moving frame 1021. At the same time, the sliding frame 401 moves left and right along the moving frame 1021 through the screw, dynamically adjusting the relative position of the nozzle 505 and the carbon fiber encapsulated tube shell on the inner support plate 302 of the frame 201.Subsequently, the spraying module 403 is activated. The spray material inside the spraying module 403 is sprayed out through the spraying channel inside the nozzle 505 to spray the surface of the carbon fiber encapsulated tube shell. During the spraying process, the cover 205 shields the spray material. After the spraying operation is completed, the spraying module 403 is turned off, and the suction module 5021 at the lower end of the central groove 502 at the bottom of the turntable 501 can be opened automatically. The operation of the suction module 5021 creates a negative pressure in the central groove 502. The negative pressure is transmitted through the connecting groove 5042 on the side of the slider 504 to the built-in groove 5051 inside the nozzle 505. The built-in groove 5051 is connected to the spraying channel inside the nozzle 505 through a circular hole, which directs the spray material through the nozzle. Residual spray material in the channel is sucked into the built-in groove 5051, then through the connecting groove 5042 and the central groove 502 into the suction module 5021. Finally, it is discharged from the side of the suction module 5021 and collected. After running for a period of time, the suction module 5021 can automatically shut down. The running time of the suction module 5021 can be set. The hydraulic cylinder 202 is activated to retract it, and the rotating frame 301 rotates in the opposite direction around the fixed axis 2011. The support plate 302 moves out of the frame 201 along with the rotating frame 301. The support plate 302 is pulled out of the slot 3012 of the rotating frame 301, and the coated carbon fiber encapsulation shell is removed, completing one coating operation.
