Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, and in particular to a cleaning device for brass strip before electroplating. Background Technology

[0002] Oil stains and oxide spots on the surface of brass strips lead to poor adhesion, uneven coating, and pitting during electroplating. Existing pickling processes cannot remove or reduce these surface problems, making it difficult to achieve ideal electroplating quality.

[0003] The current method for cleaning copper strip surfaces typically involves acid pickling, with the first step being wire brushing. However, as customers demand higher surface quality from copper strips, wire brush cleaning is no longer sufficient to meet market requirements. Some manufacturers also use roller brushes for cleaning, but to improve the cleaning effect, the roller brush pressure is set too high, which can easily damage the brass strip substrate.

[0004] For example, patent CN108312033A discloses a copper strip cleaning device, which includes a frame, a wheel brush, and a motor for driving the wheel brush to rotate. The motor and the wheel brush are mounted on the frame. The wheel brush includes a wheel brush fixing cylinder and a set of brush blades. The set of brush blades are stacked together to form a cylindrical brush body structure. The inner edge of the cylindrical brush body structure is fixed to the outer edge of the wheel brush fixing cylinder. The outer edge of the cylindrical brush body structure forms a brush surface, and the brush surface of the outer edge of the cylindrical brush body structure contacts the surface of the copper strip to be cleaned. However, the cleaning pressure cannot be adjusted according to the actual situation of the brass strip. Utility Model Content

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0023] like Figure 1 and Figure 2 As shown, the brass strip pre-plating cleaning device includes a cleaning frame, a cleaning spray structure, and an upper cleaning roller brush 2 and a lower cleaning roller brush 3 arranged opposite each other.

[0024] The cleaning frame is equipped with a roller brush pressure adjustment plate 4. The upper cleaning roller brush and the lower cleaning roller brush are respectively movably mounted on the roller brush pressure adjustment plate via corresponding sliders. The roller brush pressure adjustment plate is equipped with a drive cylinder for adjusting the position of the sliders to adjust the pressure of the cleaning roller brush.

[0025] The drive cylinder is a pneumatic cylinder; furthermore, the drive cylinder is a two-way pneumatic cylinder 6, and the upper cleaning roller brush and the lower cleaning roller brush are adjusted synchronously.

[0026] The upper cleaning roller brush is connected to an upper adjusting slider 7 at its end, and an upper drive motor for driving the upper cleaning roller brush is provided on the upper adjusting slider; the lower cleaning roller brush is connected to a lower adjusting slider 8 at its end, and a lower drive motor for driving the lower cleaning roller brush is provided on the lower adjusting slider; the cleaning roller brush is connected to the corresponding adjusting slider via a rotating shaft; the upper end of the bidirectional cylinder is connected to the upper adjusting slider, and the lower end of the bidirectional cylinder is connected to the lower adjusting slider.

[0027] This utility model has a reasonable structural design for the pre-plating cleaning device for brass strips. The upper and lower cleaning rollers are synchronously adjusted by a bidirectional cylinder set in the middle, and the pressure of the cleaning rollers can be precisely adjusted to ensure that surface impurities are efficiently removed without damaging the brass strip substrate. This ensures the cleanliness and stability of the brass strip surface and provides a good foundation for subsequent electroplating processes.

[0028] The outer side of the roller brush pressure adjustment plate 4 is provided with a vertical rail groove. The upper and lower adjustment sliders are both located in the vertical rail groove. The bidirectional cylinder is fixed in the middle of the roller brush pressure adjustment plate and is located between the upper and lower adjustment sliders. The cleaning roller brush adjustment is stable and reliable, and the cleaning roller brush shakes relatively little during the cleaning process.

[0029] The cleaning spray structure is configured to correspond to the cleaning roller brush, and cleaning spray head 5 is used; preferably, the frame is equipped with corresponding cleaning spray heads for the upper and lower cleaning roller brushes respectively; cleaning spray heads are provided on both sides of the cleaning roller brush.

[0030] like Figure 1 As shown, an inclined upper cleaning spray head is provided on each side of the upper cleaning roller brush, and an inclined lower cleaning spray head is provided on each side of the lower cleaning roller brush.

[0031] The cleaning roller brush uses an 800-mesh silicon carbide roller brush. This type of brush has advantages such as high hardness, good wear resistance, and uniform particle size, which can effectively remove or reduce oil stains and oxide spots on the surface of the brass strip. During the cleaning process, the brush pressure and rotation speed are precisely controlled to ensure that surface impurities are removed without damaging the brass strip substrate. The hardness of silicon carbide is sufficient to deal with stubborn oil stains and oxide layers, and its uniform particle size makes the cleaned surface smoother, providing a good foundation for subsequent electroplating processes.

[0032] A tap water spray system was added to the pickling line, and a spraying operation is performed after pickling. The post-pickling spray can promptly wash away residual acid and impurities on the surface, preventing secondary pollution and corrosion, further ensuring the cleanliness and stability of the brass strip surface, and reducing electroplating defects caused by acid residue; and the cleaning effect is even better when combined with the roller brush.

[0033] By adopting this invention, the problem of poor electroplating on the surface of brass strips has been effectively solved and significantly reduced. Customer feedback indicates that the adhesion of the plating layer is significantly enhanced, the uniformity of the plating layer is greatly improved, and defects such as pitting have almost disappeared. The appearance quality and performance of the product have been significantly improved, leading to increased customer satisfaction. This has brought positive impacts to the company's production and operation, enhanced its competitiveness in the market, and provided valuable experience and direction for further optimization of the production process in the future.

[0034] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0035] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
