Description

Technical Field

[0001] This utility model is a device for extending the polishing cycle of the cathode roller of a foil production machine, belonging to the field of foil production machines. Background Technology

[0002] Copper foil production machines mainly consist of polishing equipment, winding equipment, titanium rollers, and electrolytic cells. During copper foil production, the surface of the titanium rollers in the production machine gradually becomes rough due to continuous contact with the copper foil, the chemical action of the electrolyte, and mechanical wear. If the titanium roller surface is uneven, the deposition rate of copper ions on the rough surface will differ during copper foil electrodeposition. For example, in the raised parts of the titanium roller surface, the electric field strength may be relatively high, making it easier for copper ions to deposit, resulting in faster copper foil growth in these areas; while in the recessed parts, the electric field strength is lower, and the deposition rate is slower. Periodic polishing can maintain the flatness of the titanium roller surface, ensuring uniform copper foil thickness. With the use of the titanium roller, its surface roughness increases. A rough titanium roller surface will also make the surface of the produced copper foil rough. In fields with extremely high requirements for copper foil surface quality, such as the electronics industry, for producing copper foil for printed circuit boards, a very low level of surface roughness is required, usually measured by the Ra value (arithmetic mean deviation of the profile). Unpolished titanium rollers can cause the surface Ra value of copper foil to reach 1-2 μm. However, after periodic polishing, the surface Ra value of copper foil can be controlled below 0.3 μm, thus ensuring the smoothness of the copper foil surface and meeting the production requirements of high-end electronic products. Currently, in copper foil production, the peeling roller and polishing brush on the outside of the titanium roller are not on the same side of the titanium roller, that is, there is a large gap between the peeling roller and the polishing brush. During the production process, after the copper foil is peeled off by the peeling roller, about 40% of the titanium roller is exposed to the air, causing the surface of the titanium roller to oxidize rapidly, thus requiring polishing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for extending the polishing cycle of the cathode roller of the foil production machine, so as to solve the problems mentioned in the background art. This utility model increases the distance of the copper foil wrapped on the surface of the titanium roller before peeling off, thereby reducing the oxidation time of the titanium roller surface and extending the polishing cycle of the titanium roller.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a device for extending the polishing cycle of the cathode roller of a foil production machine, comprising an electrolytic cell body, a titanium roller rotatably mounted inside the electrolytic cell body, a portion of the titanium roller extending to the upper side of the electrolytic cell body, a water washing roller and an acid washing roller arranged parallel to the titanium roller on one side of the titanium roller, the water washing roller being positioned obliquely above the acid washing roller, a polishing brush arranged parallel to the titanium roller on the side of the titanium roller away from the water washing roller, a peeling roller arranged obliquely above the polishing brush, the peeling roller being arranged parallel to the titanium roller, and a winding roller for winding copper foil arranged obliquely above the peeling roller, the winding roller being arranged parallel to the titanium roller.

[0005] Furthermore, a support shaft is fixedly connected to the middle of both ends of the titanium roller, and a bearing is sleeved on the support shaft. Supports are provided on both sides of the titanium roller, and a circular opening is opened on one side of the support. The bearing is installed in the circular opening, and the support is installed on the electrolytic cell body.

[0006] Furthermore, connecting ears are installed at the lower part of the two parallel sides of the support, and the connecting ears are connected to the electrolytic cell body by screws.

[0007] Furthermore, a liquid collection hood is installed on the upper part of both sides of the electrolytic cell near the support. The upper end of the liquid collection hood is higher than the upper end of the electrolytic cell. The upper surface of the liquid collection hood and the side of the liquid collection hood facing the electrolytic cell are both open. Multiple reflux holes are opened on both sides of the electrolytic cell where the liquid collection hood is installed. The reflux holes are located inside the liquid collection hood and are located at the lower part of the liquid collection hood.

[0008] Furthermore, the bottom of the reflux hole is a plane, and the bottom of the liquid collection hood is an inclined surface that slopes towards the reflux hole, with the lowest point of the plane and the inclined surface being flush.

[0009] Furthermore, a first baffle plate and a second baffle plate are respectively provided on both sides of the support. The first baffle plate and the second baffle plate are arranged in parallel. The first baffle plate and the second baffle plate are both connected and fixed to the liquid collection hood. The lower ends of the first baffle plate and the second baffle plate are in contact with the electrolytic cell body. The ends of the first baffle plate and the second baffle plate away from the liquid collection hood extend into the electrolytic cell body.

[0010] Furthermore, an extension plate is fixedly connected to the bottom of the liquid collection hood, and the extension plate is fixedly connected to the electrolytic cell body.

[0011] The beneficial effects of this utility model are:

[0012] 1. The take-up roller and stripping roller are positioned on the side of the titanium roller close to the polishing brush. Under the constraint of the stripping roller, the distance between the position where the copper foil is peeled off from the titanium roller and the polishing brush is reduced. This reduces the exposed area of ​​the copper foil on the titanium roller after peeling off, increases the distance of the copper foil wrapped around the surface of the titanium roller before peeling off, thereby reducing the oxidation time of the titanium roller surface and extending the polishing cycle of the titanium roller.

[0013] 2. Install a liquid collection hood on the side of the electrolytic cell support. When the titanium roller rotates and the electrolyte spreads along the support shaft to the outside of the electrolytic cell, the electrolyte spreading along the support shaft is collected in the space formed by the liquid collection hood and the electrolytic cell. Then the electrolyte flows back into the electrolytic cell through the return hole, preventing the electrolyte from spreading randomly to the outside of the electrolytic cell through the support shaft.

[0014] 3. Install a first baffle plate and a second baffle plate on both sides of the support on the liquid collection hood, and make the first baffle plate and the second baffle plate contact the electrolytic cell body, thereby improving the effect of restricting the random diffusion of electrolyte.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a device for extending the polishing cycle of the cathode roller of a foil production machine, including an electrolytic cell body 1, a titanium roller 11 rotatably installed inside the electrolytic cell body 1, a portion of the titanium roller 11 extending to the upper side of the electrolytic cell body 1, a support shaft 13 fixedly connected to the middle of both ends of the titanium roller 11, a bearing 14 sleeved on the support shaft 13, a support 10 on both sides of the titanium roller 11, a round opening 18 on one side of the support 10, the bearing 14 installed in the round opening 18, the support 10 installed on the electrolytic cell body 1, and a connecting ear 15 installed at the lower part of the two parallel sides of the support 10, the connecting ear 15 being connected to the electrolytic cell body 1 by screws 16, the support 10, the bearing 14, and the support shaft 13 together support the titanium roller 11.

[0022] See Figures 1-3A liquid collecting hood 6 is installed on the upper part of both sides of the electrolytic cell 1 near the support 10. The upper end of the liquid collecting hood 6 is higher than the upper end of the electrolytic cell 1. The upper surface of the liquid collecting hood 6 and the side of the liquid collecting hood 6 facing the electrolytic cell 1 are open. Multiple reflux holes 12 are opened on both sides of the electrolytic cell 1 where the liquid collecting hood 6 is installed. The reflux holes 12 are located inside the liquid collecting hood 6 and are located at the lower part of the liquid collecting hood 6. The bottom of the reflux hole 12 is flat, and the bottom of the liquid collecting hood 6 is an inclined surface that slopes towards the reflux hole 12. The lowest point of the flat surface and the inclined surface are flush. An extension plate 7 is fixedly connected to the bottom of the electrolytic cell 1. The extension plate 7 is fixedly connected to the electrolytic cell 1. The extension plate 7 increases the connection range between the liquid collection hood 6 and the electrolytic cell 1. The liquid collection hood 6 is installed on the side of the mounting support 10 of the electrolytic cell 1. When the electrolyte spreads along the support shaft 13 to the outside of the electrolytic cell 1 during the rotation of the titanium roller 11, the electrolyte spreading along the support shaft 13 is collected in the space formed by the liquid collection hood 6 and the electrolytic cell 1. Then the electrolyte flows back into the electrolytic cell 1 from the return hole 12, preventing the electrolyte from spreading to the outside of the electrolytic cell 1 through the support shaft 13 at will.

[0023] See Figure 1 and Figure 3 The support 10 has a first baffle plate 5 and a second baffle plate 17 on both sides. The first baffle plate 5 and the second baffle plate 17 are arranged in parallel. The first baffle plate 5 and the second baffle plate 17 are both connected and fixed to the liquid collection hood 6. The ends of the first baffle plate 5 and the second baffle plate 17 away from the liquid collection hood 6 extend into the electrolytic cell 1. The first baffle plate 5 and the second baffle plate 17 located on both sides of the support 10 are installed on the liquid collection hood 6 and are made to contact the electrolytic cell 1, thereby improving the effect of restricting the random diffusion of electrolyte.

[0024] See Figure 1 A washing roller 9 and an acid pickling roller 8 are arranged parallel to the titanium roller 11 on one side. The washing roller 9 is positioned diagonally above the acid pickling roller 8. A polishing brush 3 is arranged parallel to the titanium roller 11 on the side of the titanium roller 11 away from the washing roller 9. A peeling roller 4 is positioned diagonally above the polishing brush 3. The peeling roller 4 is arranged parallel to the titanium roller 11. A winding roller 2 for winding copper foil is positioned diagonally above the peeling roller 4. The winding roller 2 is arranged parallel to the titanium roller 11. By positioning the winding roller 2 and the peeling roller 4 on the side of the titanium roller 11 close to the polishing brush 3, the distance between the position where the copper foil is peeled off from the titanium roller 11 and the polishing brush 3 is reduced under the restriction of the peeling roller 4. This reduces the exposed area of ​​the titanium roller 11 after the copper foil is peeled off, increases the distance of the copper foil wrapped around the surface of the titanium roller 11 before peeling off, thereby reducing the oxidation time of the titanium roller 11 surface and extending the polishing cycle of the titanium roller 11.
