Description

Technical Field

[0001] The invention relates to the technical field of copper foil processing, in particular to a roughening and curing device for producing high-temperature elongation RTF copper foil. Background Art

[0002] RTF copper foil is a reverse copper foil, both sides of which have been roughened to varying degrees, thereby increasing the peel strength of the copper foil and making it easier to bond with other materials as an intermediate layer. RTF copper foil has the advantages of high conductivity, good etching properties, and the ability to improve the yield rate of printed circuit boards. During the manufacturing and use of electronic products, copper foil often needs to be bent, such as bonding and assembly. Improving the high-temperature elongation of copper foil can reduce the possibility of cracks or breaks at the bends, thereby extending the service life of electronic products; In the actual production of copper foil, additives and specific process parameters are usually used to make the electrolyte obtain relatively large and uniform equiaxed grains during the electrolysis process, thereby increasing the slip distance of the grains when the copper foil is stretched under high temperature conditions while ensuring the tensile strength, thereby improving the high temperature elongation of the copper foil; In the prior art, the patent with application publication number CN 113103094 A discloses a roughening and curing device for ultra-thick copper foil with high elongation. When the copper foil reaches the upper end of the traction roller through the unwinding roller, the semicircular gear will mesh with the upper end of the movable tooth plate when it rotates, driving it to move.

The telescopic end of the electric push rod 41 drives the vertical plate 3 to move up and down through the connecting block 42, so that the sandpaper layer 11 is removed from the copper foil, thereby facilitating the replacement of the sandpaper layer 11.

[0019] The interior of the mounting base 9 is hollow, and the middle interface of the mounting base 9 is a triangular structure. The interior of the mounting base 9 is connected to the interior of the dust collection unit 5 through a hollow rotating shaft 10. The dust collection unit 5 includes a dust collector 51, a dust collection pipe 52 and a rotary joint 53. The dust collector 51 is installed on the side of the vertical plate 3, and the dust collection pipe 52 is connected and fixed at the suction port position of the dust collector 51. The end of the dust collection pipe 52 is rotatably connected to the end of the rotating shaft 10 through the rotary joint 53. The dust collector 51 is electrically connected to the PLC controller 2. The dust in the mounting base 9 enters the dust collection pipe 52 through the hollow rotating shaft 10, and the dust in the dust collection pipe 52 is collected by the dust collector 51.

[0020] The driving mechanism 7 includes a worm gear 71, a servo motor 72 and a worm 73. The worm 73 is rotatably mounted on the ear seat of the vertical plate 3.

The worm gear 71 is driven by the rotating shaft 10 to rotate with the mounting seat 9, so that the unused sandpaper layer 11 is opposite to the copper foil surface. Then, the sandpaper layer 11 is restored to its original position under the drive of the lifting mechanism 4. It is convenient to replace the sandpaper layer 11. At the same time, the spare sandpaper layer 11 can be replaced in time to reduce the downtime and ensure the production efficiency.

[0021] The dust collecting unit 8 includes a dust collecting cover 81 and a dust suction port 84. The dust suction port 84 is opened at the bottom of the dust collecting cover 81 near the end side. The dust collecting unit 8 also includes a movable rod 82, a spring 83 and a limit block 85. The movable rod 82 is movably connected to the mounting seat 9. The limit block 85 is fixed to one end of the movable rod 82. The other end of the movable rod 82 is fixedly connected to the dust collecting cover 81. The limit block 85 is arranged on the inner side of the mounting seat 9. The spring 83 is sleeved on the movable rod 82. The spring 83 is arranged between the mounting seat 9 and the dust collecting cover 81. Rod 82 is a hollow rod, one end of which is connected to the inside of the dust hood 81, and the other end of which is connected to the inside of the mounting seat 9. When the copper foil passes through the unwinding roller and reaches the upper end of the traction roller, the sandpaper layer 11 is rubbed and polished against the surface of the copper foil. During the polishing process, dust enters the dust hood 81 through the dust suction port 84, and the dust in the dust hood 81 enters the mounting seat 9 through the hollow structure of the movable rod 82, which can collect dust while polishing, thereby preventing dust from spreading and affecting the workshop environment.

[0022] The connecting mechanism 6 includes a nylon velvet belt 61 and a nylon hook belt 62. The nylon velvet belt 61 is arranged on the side of the sandpaper layer 11, and the nylon hook belt 62 is arranged on the side of the dust cover 81. The nylon hook belt 62 and the nylon velvet belt 61 are bonded to each other. By pulling the worn sandpaper layer 11, the nylon hook belt 62 and the nylon velvet belt 61 are separated, so that the worn sandpaper layer 11 can be removed from the dust cover 81. It is easy to replace and convenient to use.

[0023] The working principle of a roughening and curing device for high-temperature elongation RTF copper foil production provided by the present invention is as follows: when the copper foil passes through the unwinding roller and reaches the upper end of the traction roller, the sandpaper layer 11 is rubbed and polished with the surface of the copper foil. During the polishing process, dust enters the dust collecting hood 81 through the dust suction port 84, and the dust in the dust collecting hood 81 enters the mounting seat 9 through the hollow structure of the movable rod 82. The dust in the mounting seat 9 enters the dust suction pipe 52 through the hollow structure of the rotating shaft 10. The dust in the dust suction pipe 52 is collected by the dust collector 51. When the sandpaper layer 11 is rubbed and polished with the copper foil, the dust collecting hood 81 drives the movable rod 82 and the mounting seat 9 to slide relative to each other. At this time, the spring 83 is compressed, and the deformation force of the spring 83 reacts to the dust collecting hood. The cover 81 is provided so that the sandpaper layer 11 on the dust collecting cover 81 is pressed against the surface of the copper foil. When the sandpaper layer 11 needs to be replaced, the telescopic end of the electric push rod 41 drives the vertical plate 3 to move up and down through the connecting block 42, so that the sandpaper layer 11 is removed from the copper foil. Then, the output shaft of the servo motor 72 drives the worm 73 to rotate, and the worm 73 is engaged with the worm wheel 71. The worm wheel 71 is driven by the rotating shaft 10 to rotate with the mounting seat 9, so that the unused sandpaper layer 11 is opposite to the copper foil surface. Then, the sandpaper layer 11 is restored to its original position under the drive of the lifting mechanism 4. At this time, the nylon hook belt 62 and the nylon velvet belt 61 are separated by pulling the worn sandpaper layer 11, so that the worn sandpaper layer 11 can be removed from the dust collecting cover 81.
