Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production equipment, in particular to an edge shielding device for an anode plate in a copper foil surface treatment machine. Background Art

[0002] The copper foil produced by a copper foil former is called raw foil or rough foil, which cannot meet the requirements of downstream production. It must be electroplated on the surface of the rough foil by a surface treatment machine to improve various performance indexes of the rough foil, such as peel resistance performance index, antioxidant performance index, etc. through copper plating, zinc plating and chromium plating.

[0003] At present, the width of copper foil is usually 1350mm or 1380mm. In order to make copper foils with different widths all operate on the surface treatment machine, the anode plate needs to be designed with a wider width, such as 1400mm. When processing a 1350mm copper foil, since the anode plate is wider than the copper foil, the electric field line distribution at the edge of the copper foil is more concentrated. After electroplating, the edge thickness of the copper foil is thicker than that in the middle. When winding this kind of copper foil, the edge of the copper foil is prone to warping, resulting in the inability to wind a large roll normally. Moreover, when the edge thickness of the copper foil is thicker than that in the middle, it will also cause a difference in the electroplated bright color, affecting the quality of the copper foil. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides an edge shielding device for an anode plate in a copper foil surface treatment machine.

[0005] The technical solution adopted by the utility model is as follows: an edge shielding device for an anode plate in a copper foil surface treatment machine, the anode plate is arranged on one side of the conveying line of the copper foil, the width of the anode plate is greater than the width of the copper foil, both sides of the anode plate extend out of the covering area of the copper foil and form an external area, the self - extending direction of the anode plate is set as the long direction, the edge shielding device is arranged on the external area and at least includes a shielding strip, and the shielding strip includes:

[0006] An anode shielding plate arranged along the long direction on the side close to the anode plate;

[0007] A cathode shielding plate arranged along the long direction on the side close to the copper foil, and one end extends to the edge of the copper foil;

[0008] A connection structure is arranged between the anode shielding plate and the cathode shielding plate.

[0009] The following also provides several optional ways, which are not additional limitations to the above overall solution, but only further supplements or optimizations. Without technical or logical contradictions, each optional way can be combined with the above overall solution alone, or multiple optional ways can be combined with each other.

[0010] Preferably, the shielding strip completely covers the external area.

[0011] Preferably, the connecting structure is a connecting plate, and the connecting plate is connected between the anode shielding plate and the cathode shielding plate.

[0012] Preferably, the edge shielding device further includes a shielding housing, and a placement cavity is provided on the shielding housing, and one side of the shielding strip is placed in the placement cavity.

[0013] Preferably, a plurality of spaced-apart strip-shaped slot holes are provided on the shielding housing along the longitudinal direction, the strip-shaped slot holes extend along the transverse direction, and a plurality of spaced-apart screw holes are provided on the cathode shielding plate along the longitudinal direction, and the positions of the strip-shaped slot holes and the screw holes correspond to each other.

[0014] More preferably, a handle is fixed on the side of the shielding strip located outside the placement cavity.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] By providing an edge shielding device at the edge of the anode plate, the edges of both the anode plate and the copper foil can be shielded simultaneously, thereby effectively shielding the electric field lines at the edge of the copper foil. At this time, the thickness of the edge of the copper foil will not be relatively thick due to the concentration of electric field lines. After electroplating, the thickness of the edge of the copper foil and the thickness of the middle position are basically the same, and there will be no edge warping phenomenon, which is convenient for subsequent normal winding of the large copper foil roll. In addition, it will not cause chromatic aberration in the electroplated bright color, and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Specific implementation scheme: Refer to Figures 1 - 4 , the present utility model is an edge shielding device for the anode plate in a copper foil surface treatment machine. The anode plate 1 is arranged on one side of the conveying line of the copper foil 2. The width of the anode plate 1 is greater than the width of the copper foil 2. Both sides of the anode plate 1 extend out of the covering area of the copper foil 2 and form an external area. The self-extending direction of the anode plate 1 is set as the long side. The edge shielding device is arranged on the external area and at least includes a shielding strip 3. The shielding strip 3 includes:

[0028] An anode shielding plate 31, arranged along the long side on the side close to the anode plate 1;

[0029] The cathode shielding plate 32 is arranged along the longitudinal direction on one side close to the copper foil 2, and one end extends to the edge of the copper foil 2;

[0030] A connection structure is provided between the anode shielding plate 31 and the cathode shielding plate 32.

[0031] As a preferred implementation manner of this embodiment, to ensure that the edge shielding device can completely shield the electric field lines at the edge of the copper foil 2 and prevent more electric field lines from entering the edge of the copper foil 2, the shielding strip 3 completely covers the external area.

[0032] Please refer to Figure 1 , the connection structure is a connecting plate 33, and the connecting plate 33 is connected between the anode shielding plate 31 and the cathode shielding plate 32.

[0033] Here, setting the connection structure as the connecting plate 33 can make the shielding strip 3 an integral structure, which is convenient for the installation of the shielding strip 3.

[0034] Please refer to Figures 2 - 4 , it can be seen that in this embodiment, the edge shielding device further includes a shielding housing 4. A placement cavity 42 is provided on the shielding housing 4, and one side of the shielding strip 3 is placed in the placement cavity 42.

[0035] Then, a plurality of mutually spaced strip-shaped slot holes 41 are provided on the shielding housing 4 along the longitudinal direction. The strip-shaped slot holes 41 extend along the transverse direction. A plurality of mutually spaced screw holes 34 are provided on the cathode shielding plate 32 along the longitudinal direction. The positions of the strip-shaped slot holes 41 and the screw holes 34 correspond.

[0036] In this embodiment, a fixing screw is screwed into the screw hole 34, and the screw rod of the fixing screw passes through the strip-shaped slot hole 41.

[0037] More specifically, a handle 5 is fixed on the side of the shielding strip 3 located outside the placement cavity 42.

[0038] In this embodiment, the setting of the shielding housing 4 is to facilitate the adjustment of the shielding width of the edge shielding device. When the width of the copper foil 2 passing through the anode plate 1 changes, such as when the width of the copper foil 2 switches from 1380 mm to 1350 mm, the shielding width needs to be increased.

[0039] When the shielding width needs to be increased, in this embodiment, first, all the fixing screws need to be unscrewed; then, hold the handle 5 with hand and pull the shielding strip 3 outwards along the transverse direction (since the shielding strip 3 is placed in the placement cavity 42 in a matching manner, during the outward pulling process, the screw hole 34 on the shielding strip 3 is always within the coverage area of the strip-shaped slot hole 41); after pulling the shielding strip 3 out to an appropriate extent, please refer to Figure 3, re-fix the fixing screw between the strip-shaped slot hole 41 and the screw hole 34 to complete the fixing of the shielding strip 3, and at this time, the shielding width adjustment is completed.

[0040] Note that in other embodiments, the shielding housing 4 may not be provided, and instead, a plurality of strip-shaped slot holes 41 spaced apart from each other along the longitudinal direction may be provided on the shielding strip 3, and the strip-shaped slot holes 41 extend transversely. In this case, the width of the shielding strip 3 needs to be ensured to be relatively wide (which can meet the adjustment of all shielding widths). In addition, a plurality of guide posts need to be fixed on the anode plate 1, and the guide posts pass through the strip-shaped slot holes 41 in a matching manner. When the shielding width needs to be adjusted, directly pull the shielding strip 3 transversely, and at this time, the guide posts slide along the strip-shaped slot holes 41.

[0041] The edge shielding device of the anode plate in a copper foil surface treatment machine of the present invention is only the preferred embodiment of the present invention as described above, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
