Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate production technology, specifically to a copper clad laminate surface anti-oxidation treatment device. Background Technology

[0002] Anti-oxidation treatment of the copper substrate in copper-clad laminates is to prevent the copper layer from oxidizing in the air (forming copper oxide or cuprous oxide), which would affect weldability, conductivity and long-term reliability. Therefore, anti-oxidation treatment equipment is required in the production process of copper-clad laminates to treat the copper substrate against oxidation.

[0003] When performing anti-oxidation treatment on copper substrates, the copper substrate needs to be immersed in OSP solution to form a protective film on the surface of the copper substrate. After drying, the copper substrate needs to be dried. This requires the use of drying equipment and film-forming equipment. After the copper substrate film is formed, it needs to be transferred to the drying equipment. As a result, the anti-oxidation treatment device for copper substrates has low integration and a large footprint. It is also inconvenient to directly dry the copper substrate after film formation. Therefore, we propose an anti-oxidation treatment device for copper clad laminates to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, copper coils enter the solution tank through the feed inlet. An OSP solution forms a protective film on the copper surface. The copper is guided by first, second, third, and fourth guide rollers. It then enters the drying tank through a connecting port and exits through the discharge port after passing the fifth guide roller. While the copper enters the drying tank, a scraping mechanism scrapes off the solution adhering to both sides of the copper substrate. The scraped copper substrate passes between U-shaped tubes, where a hot air mechanism delivers hot air. The hot air is then blown out through the air outlet to both sides of the copper substrate for drying. This copper-clad laminate surface anti-oxidation treatment device allows for direct drying of the copper substrate after anti-oxidation treatment. The solution tank and drying tank are arranged vertically, which not only increases the integration of the copper substrate anti-oxidation treatment device but also effectively reduces the equipment footprint, avoids the need for transferring the copper substrate, and effectively improves the efficiency of the anti-oxidation treatment of the copper substrate.

[0015] 2. In this utility model, when the copper material enters the drying tank through the connecting port and passes between the scraping mechanism, the scraper blade is tightly pressed against the outer surface of the copper material by a spring. At the same time, the scraper blade is made of rubber material to increase the contact area between the scraper blade and the copper material, so that the solution attached to the outer surface of the copper material can be scraped off by the scraper blade, so that the copper material can be dried by hot air in the future.

[0016] 3. In this utility model, when the hot air blower is working, outside air enters the filter box through the air inlet. After the impurities in the air are filtered by the filter screen, the air enters the hot air blower through the connecting pipe. After being heated, the hot air enters the U-shaped pipe through the air outlet pipe. This hot air mechanism can not only provide hot air, but also filter impurities in the hot air, preventing hot air containing impurities from being blown onto the outer surface of the copper material and preventing impurities from adhering to the outer surface of the copper material.

[0024] The solution tank 2 is rotatably connected to the inside of the connecting port 7. The drying tank 3 is rotatably connected to the top of the inner side of the connecting port 7. The partition 6 is symmetrically provided with a scraping mechanism on both sides of the top of the connecting port 7. The drying tank 3 is installed with a U-shaped tube 22 above the scraping mechanism. The U-shaped tube 22 is provided with an air outlet 23 on the inner side near the bottom. The top of the box 1 is provided with a hot air mechanism for supplying hot air to the U-shaped tube 22.

[0025] Copper coils enter the solution tank 2 through the feed inlet 8. An OSP solution forms a protective film on the copper surface. The copper is guided by the first guide roller 10, the second guide roller 11, the third guide roller 12, and the fourth guide roller 13. The copper then enters the drying tank 3 through the connecting port 7, and exits from the discharge port 9 after passing through the fifth guide roller 14. While the copper enters the drying tank 3, a scraping mechanism scrapes off the solution adhering to both sides of the copper substrate. The scraped copper substrate passes between U-shaped tubes 22, where a hot air mechanism delivers hot air. The hot air is then blown onto both sides of the copper substrate through the air outlet 23, drying the copper substrate. This copper-clad laminate surface anti-oxidation treatment device allows for direct drying of the copper substrate after anti-oxidation treatment. The vertical arrangement of the solution tank 2 and the drying tank 3 not only increases the integration of the copper substrate anti-oxidation treatment device but also effectively reduces the equipment footprint, avoids the need for transferring the copper substrate, and effectively improves the efficiency of the anti-oxidation treatment of the copper substrate.

[0026] Please see Figures 1 to 3 The box 1 has openings 4 on the same side as the solution tank 2 and the drying tank 3. The openings 4 are sealed by the sealing plate 5. The bottom of the inner side of the drying tank 3 is inclined downward towards the connecting port 7. When the sealing plate 5 is open, the copper material can be easily guided around the first guide roller 10, the second guide roller 11, the third guide roller 12, the fourth guide roller 13 and the fifth guide roller 14 through the openings 4, so as to guide the copper material through the interior of the solution tank 2 and the drying tank 3.

[0027] Please see Figures 1 to 3The scraping mechanism includes a fixed bracket 15. Fixed brackets 15 are symmetrically fixedly connected to the top of both sides of the partition 6 corresponding to the top of the connecting port 7. A top plate 16 is provided on the side of the fixed bracket 15 near the connecting port 7. A scraper blade 17 is fixedly connected to the side of the top plate 16 near the connecting port 7. Guide grooves 18 symmetrically penetrate the fixed bracket 15. A guide rod 19 is fixedly connected to the side of the top plate 16 corresponding to the guide groove 18. A baffle 20 is fixedly connected to the end of the guide rod 19 away from the top plate 16. The guide rod 19 is connected to the top plate 16 and the fixed bracket 15. A spring 21 is fitted onto the rod 19. The scraper 17 has a tapered cross-section on the side away from the top plate 16 and is made of rubber. When the copper material enters the drying tank 3 through the connecting port 7, the scraper 17 presses tightly against the outer surface of the copper material through the spring 21. At the same time, the rubber material scraper 17 increases the contact area between the scraper 17 and the copper material, so that the solution adhering to the outer surface of the copper material can be scraped off by the scraper 17, so that the copper material can be dried by hot air in the future.

[0028] Please see Figures 1 to 3 The hot air mechanism includes a hot air blower 24. The hot air blower 24 and the filter box 26 are symmetrically installed on the upper part of the housing 1 near the middle. The hot air blower 24 is connected to the U-shaped pipe 22 through the air outlet pipe 25. The filter screen frame 27 is installed in the middle of the inner side of the filter box 26. The filter box 26 is connected to the hot air blower 24 near the upper side through the connecting pipe 28. The filter box 26 has an air inlet 29 near the lower side. When the hot air blower 24 is working, the outside air enters the filter box 26 through the air inlet 29. After the impurities in the air are filtered by the filter screen frame 27, the air enters the hot air blower 24 through the connecting pipe 28. After being heated, the hot air enters the U-shaped pipe 22 through the air outlet pipe 25. This hot air mechanism can not only provide hot air, but also filter the impurities in the hot air, preventing hot air containing impurities from being blown to the outer surface of the copper material and preventing impurities from adhering to the outer surface of the copper material.

[0029] Working Principle: This is a copper-clad laminate surface anti-oxidation treatment device. Copper coils enter the solution tank 2 through the feed inlet 8. An OSP solution forms a protective film on the copper surface. The copper is guided by first guide rollers 10, second guide rollers 11, third guide rollers 12, and fourth guide rollers 13. The copper then enters the drying tank 3 through the connecting port 7, and exits from the discharge port 9 after passing through the fifth guide roller 14. While the copper enters the drying tank 3, a scraping mechanism scrapes off the solution adhering to both sides of the copper substrate. The scraped copper substrate then... Between the U-shaped tubes 22, the hot air mechanism delivers hot air into the U-shaped tubes 22, and blows the hot air through the air outlets 23 to both sides of the copper substrate to dry the copper substrate. Through this copper-clad laminate surface anti-oxidation treatment device, the copper substrate can be directly dried after anti-oxidation treatment. Moreover, the solution tank 2 and the drying tank 3 are arranged vertically, which not only makes the integration of the copper substrate anti-oxidation treatment device higher, but also effectively reduces the equipment footprint, avoids the transfer of the copper substrate, and effectively improves the anti-oxidation treatment efficiency of the copper substrate.

[0030] When the sealing plate 5 is opened, the opening 4 facilitates the guidance of the copper material around the first guide roller 10, the second guide roller 11, the third guide roller 12, the fourth guide roller 13, and the fifth guide roller 14, so as to guide the copper material through the interior of the solution tank 2 and the drying tank 3. When the copper material enters the drying tank 3 through the connecting port 7, and the copper material passes between the scraping mechanism, the scraper 17 is tightly pressed against the outer surface of the copper material by the spring 21. At the same time, the scraper 17 is made of rubber material to increase the contact area between the scraper 17 and the copper material, so as to scrape the copper material from the outside through the scraper 17. The solution adhering to the surface is scraped off so that the copper material can be dried by hot air later. When the hot air blower 24 is working, the outside air enters the filter box 26 through the air inlet 29. After the impurities in the air are filtered by the filter screen frame 27, the air enters the hot air blower 24 through the connecting pipe 28. After being heated, the hot air enters the U-shaped pipe 22 through the air outlet pipe 25. This hot air mechanism can not only provide hot air, but also filter the impurities in the hot air, so as to prevent the hot air containing impurities from being blown to the outer surface of the copper material and to prevent impurities from adhering to the outer surface of the copper material.

[0031] 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.
