Description

Technical Field

[0001] This utility model relates to a shielding fixture and electroplating equipment, belonging to the technical field of electroplating equipment. Background Technology

[0002] Currently, in the electroplating industry, film thickness is affected by current density, especially when the product is used as the cathode. When the product is too wide, the difference in electric field between the sides and the middle becomes significant, and the current lines are more concentrated at the edges, resulting in a significantly higher current density at the edges than in the middle. This edge effect directly causes the coating thickness on the sides to be greater than that in the middle, leading to uneven electroplated film thickness and hindering production efficiency.

[0003] In existing technologies, shielding measures or devices are often used to alter the current density distribution. Chinese patent document CN212610969U discloses an adjustable shielding device for achieving uniform electroplated film thickness. While this device can be adjusted in position within the plating tank, it cannot simultaneously shield both ends of the product, nor can it accurately determine the position of the shielding plates to ensure symmetrical placement and more uniform film thickness, thus improving the quality of the electroplated product. Utility Model Content

[0004] This utility model provides a masking fixture and electroplating equipment, which solves the problems in the prior art where the coating thickness is uneven between the two ends and the middle area of ​​the product, and the inability to simultaneously mask both ends of the product, and makes the two masking plates symmetrically arranged to make the film thickness of the product more uniform and improve the quality of electroplated products.

[0005] This utility model is achieved through the following technical solution:

[0006] Firstly, this utility model provides a shielding fixture, including...

[0007] A fixing plate, wherein the fixing plate is provided with strip holes;

[0008] Two shielding panels are symmetrically installed on both sides of the fixed plate.

[0009] A knob passes through the strip hole and is connected to the shielding plate, and the shielding plate is slidably connected to the fixing plate through the knob.

[0010] In one embodiment of this utility model, the strip-shaped hole is provided with scale lines along its length. The position of the shielding plate can be obtained by reading the scale lines. By adjusting the other shielding plate to the corresponding position, the two shielding plates are symmetrically arranged, ensuring that the shielding area of ​​the product by the two shielding plates is the same, thereby improving the coating uniformity of the product and enhancing the electroplating quality.

[0011] In one embodiment of this utility model, there are two fixing plates, which are distributed at both ends of the shielding plate.

[0012] In one embodiment of this utility model, each of the fixing plates is provided with two strip holes, and the two strip holes are symmetrically arranged.

[0013] In one embodiment of this utility model, a connector is included, and the shielding plate is connected to the knob through the connector.

[0014] In one embodiment of this utility model, a threaded hole is provided on one side of the connector, and the knob passes through the strip hole and connects to the threaded hole of the connector.

[0015] In one embodiment of this utility model, the shielding plate and the connecting member are detachably connected, facilitating later maintenance and replacement.

[0016] In one embodiment of this invention, the shielding plate is provided with holes. The plating solution can be sprayed onto the surface of the product through the holes, which can make the distribution of metal ions in the plating solution more uniform and improve the uniformity of the coating.

[0017] In one embodiment of this utility model, a mounting plate is also included, which is mounted on both sides of the fixing plate.

[0018] Secondly, this utility model provides an electroplating device, including the aforementioned shielding fixture. The electroplating device also includes an anode plate and rollers, with the shielding fixture installed between the anode plate and the rollers.

[0019] Beneficial effects

[0020] This utility model provides a masking fixture comprising a fixed plate and two masking plates. These two plates simultaneously mask both ends of the product, reducing the current density at both ends and thus decreasing the coating thickness, resulting in a more uniform coating thickness and improved product quality. The fixed plate has strip-shaped holes and scale lines. A knob passes through the strip-shaped holes and connects to the masking plates, allowing the masking plates to slide along the holes and be fixed by the knob. This enables adjustment of the masking plate position, making the fixture suitable for products of various sizes. By observing the scale readings, the position of the masking plates can be determined. Symmetrical placement of the two masking plates ensures that the masking area on both sides is the same, resulting in a more uniform coating thickness and improved electroplated product quality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] like Figures 1 to 5 As shown, this application provides a masking fixture for masking both ends of an electroplated product, resulting in a more uniform film thickness and improved product quality. The masking fixture 100 includes a fixing plate 1, a knob 2, a masking plate 3, a connector 4, and a mounting plate 5. Both ends of the masking plate 3 are connected to the connector 4, which is fixed to the fixing plate 1 by the knob 2 and can slide along the fixing plate 1. The mounting plate 5 is installed on both sides of the fixing plate 1. The masking fixture 100 is installed in the electroplating equipment via the mounting plate 5. By masking both ends of the electroplated product with the masking plate 3, the current density at both ends of the product is reduced, thereby reducing the film thickness at both ends of the product, resulting in a more uniform film thickness and improved product quality.

[0032] like Figures 1 to 3 As shown, in some embodiments, there are two fixing plates 1. The fixing plates 1 are provided with strip holes 11. The sides of the strip holes 11, that is, along their length direction, are provided with scale lines 12. Each fixing plate 1 is provided with two strip holes 11, and the two strip holes 11 are symmetrically arranged.

[0033] In some embodiments, the shielding plate 3 is a rectangular plate, and there are two shielding plates 3, symmetrically installed on both sides of the fixing plate 1, used to shield the two ends of the product to prevent the coating from being thicker at the ends and thinner in the middle, resulting in uneven coating. Multiple holes 31 are evenly distributed on the shielding plate 3, allowing the plating solution to pass through the holes 31 and be sprayed onto the surface of the product, thus making the distribution of metal ions in the plating solution more uniform and improving the uniformity of the coating. Both ends of the shielding plate 3 are connected to the connecting member 4, and the connecting member 4 has a threaded hole on the side facing away from the shielding plate 3. The knob 2 passes through the strip hole 11 and connects to the threaded hole on the connecting member 4, allowing the shielding plate 3 to slide along the length of the strip hole 11, thereby adjusting the position of the shielding plate 3 and making the shielding fixture 100 suitable for products of various sizes. Tightening the knob 2 can fix the shielding plate 3 in the desired position. The position of the shielding plate 3 can be obtained by reading the scale line 12. The other shielding plate 3 is adjusted to the corresponding position to ensure that the two shielding plates 3 are set symmetrically and that the shielding area of ​​the product by the two shielding plates 3 is the same, thereby improving the coating uniformity of the product and improving the electroplating quality of the product.

[0034] Optionally, the shielding plate 3 and the connector 4 are detachably connected. Specifically, in this embodiment, the shielding plate 3 and the connector 4 can be connected by screws. This facilitates later maintenance and replacement.

[0035] In addition, such as Figures 4 to 5 As shown, this application also provides an electroplating apparatus using the aforementioned masking fixture 100. The electroplating apparatus 200 further includes an anode plate 6, a roller 7, and a nozzle 8. The masking fixture 100 is mounted in the electroplating apparatus 200 via a mounting plate 5. The anode plate 6 is mounted on one side of the masking fixture 100. The nozzle 8 is used to spray electroplating solution onto the surface of the product and is mounted between the anode plate 6 and the masking fixture 100. The roller 7 is mounted on the side of the masking fixture away from the anode plate 6. The product is a rectangular sheet structure, placed on the roller 7, and driven on the roller 7. The product is connected to the cathode of the electroplating apparatus, serving as the cathode in the electroplating process. Because the electroplating apparatus uses the masking fixture 100 described above, it possesses the advantages mentioned above.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
