Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a water-blocking structure for electroplating. Background Technology

[0002] Electroplating solutions are a crucial component of the electroplating process, primarily composed of an electrolyte containing target metal ions and various additives. Their function is to provide metal ions for the electroplating process, and the additives adjust the uniformity, gloss, and adhesion of the plating layer. Common electroplating solutions include nickel plating solutions, chromium plating solutions, and zinc plating solutions, each with a different formulation depending on the target metal and process requirements. The performance of electroplating solutions directly affects the quality of the plating layer; therefore, their preparation and use require strict control of parameters such as pH value, temperature, and concentration.

[0003] In existing continuous plating processes, wires are typically electroplated in an electroplating tank first, and then cleaned in a cleaning tank to remove the electroplating chemicals adhering to the electroplated material and prevent corrosion of the workpiece. As a result, the electroplating chemicals adhering to the electroplated material flow into a wastewater tank along with the cleaning water for wastewater treatment. During this process, the adhering electroplating chemicals are wasted. Electroplating chemicals are usually quite expensive, and washing them off directly results in waste and increases production costs to some extent. Utility Model Content

[0006] (II) Technical Solution

[0007] The purpose of this utility model is to provide a water-blocking structure for electroplating, which includes a recovery tank and an air pump disposed outside the recovery tank. The recovery tank is provided with a slot, and a water-blocking bracket is disposed near the slot. A bamboo-joint air pipe connected to the air pump is disposed adjacent to the water-blocking bracket, and the bamboo-joint air pipe is provided with a nozzle. The water-blocking bracket includes an upper adjusting plate, a lower adjusting plate, and water-blocking wheels. The upper adjusting plate is disposed at the upper end of the water-blocking bracket and is opposite to the lower adjusting plate.

[0015] (III) Beneficial Effects

[0016] After electroplating, the electroplated strip passes through the water-blocking wheel, where the electroplating solution adhering to the surface of the strip is physically squeezed or scraped off, which also serves as a guide. In addition, the unevenness or complex shape of the strip surface may cause solution residue. This residual solution is blown into the recovery tank by the airflow output from the nozzle of the bamboo joint air tube. In this process, the water adhering to the electroplated strip is reduced, which saves electroplating solution to a certain extent and reduces costs. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] The following is in conjunction with the appendix Figures 1 to 4 To further describe, this utility model discloses a water-blocking structure for electroplating, including a recovery tank 1 and an air pump (not shown) disposed outside the recovery tank 1. The recovery tank 1 is provided with a slot 2 for accommodating the electroplating material strip 6. A water-blocking bracket 5 is disposed near the slot 2. A bamboo-joint air pipe 3 connected to the air pump is disposed near the water-blocking bracket 5. The bamboo-joint air pipe 3 is provided with a nozzle 4. The water-blocking bracket 5 includes an upper adjusting plate 52, a lower adjusting plate 53, and water-blocking wheels 54. The upper adjusting plate 52 is disposed at the upper end of the water-blocking bracket 5 by adjusting screws 55 and is disposed opposite to the lower adjusting plate 53. There are two water-blocking wheels 54, which are disposed side by side between the upper adjusting plate 52 and the lower adjusting plate 53 to form a channel that allows the electroplating material strip 6 to pass through. The nozzle 4 on the bamboo-joint air pipe 3 is aligned with the channel formed between the two water-blocking wheels 54, so that the output airflow can blow the electroplating solution attached to the electroplating material strip 6 back into the electroplating tank.

[0026] In a preferred embodiment, the water-blocking bracket 5 further includes a mounting plate 51, with an upper adjusting plate 52 and a lower adjusting plate 53 respectively disposed at the upper and lower ends of the mounting plate 51. The mounting plate 51 is generally L-shaped, with a mounting hole 514 at one end to fix the mounting plate 51 in the recycling tank 1 through the mounting hole 514, thus completing the installation of the water-blocking bracket 5. The other end has an installation notch 511 and a dovetail groove 513 respectively at the upper and lower parts. The installation notch 511 has a mounting screw hole 512 to fix the upper adjusting plate 52 through the mounting screw hole 512 and the adjusting screw 55. The dovetail groove 513 is slidably adapted to the tenon 531 on the lower adjusting plate 53.

[0027] In a preferred embodiment, one end of the upper adjusting plate 52 is provided with an adjusting hole 521, which is elongated and can be used to adjust the installation position. The other end of the upper adjusting plate 52 is provided with a connecting through hole 522, which is a countersunk hole. There are two connecting through holes 522, which are used to insert and pass through the rotating shaft 541 so that the rotating shaft 541 is inserted and installed on the shaft hole 533 through the water-blocking wheel 54.

[0028] In a preferred embodiment, a tenon 531 is provided at one end of the lower adjusting plate 53, which is adapted to the dovetail groove 513 on the mounting plate 51. A water collection trough 532 is provided at the other end of the lower adjusting plate 53. When the electroplating strip 6 passes between the two water blocking wheels 54, the electroplating solution squeezed or scraped off by the two water blocking wheels 54 will flow into the water collection trough 532 and fall into the recycling tank 1 through the water outlet 534 at the edge of the water collection trough 532 for centralized recycling.

[0029] In a preferred embodiment, the water collection tank 532 is provided with two shaft holes 533, and the edge of the water collection tank 532 is provided with a water outlet 534, from which the electroplating solution flowing down from the water blocking wheel 54 falls into the recycling tank 1.

[0030] In a preferred embodiment, the water-blocking wheel 54 is a sponge wheel, and a rotating shaft 541 is provided inside it. A limiting ring 542 is provided at the upper end of the rotating shaft 541. During installation, the rotating shaft 541 can be rotatably inserted into and passed through the connecting through hole 522, and is limited by the limiting ring 542.

[0031] In summary, after electroplating, the electroplating strip passes through the water-blocking wheel, where the electroplating solution adhering to its surface is physically squeezed or scraped off, which also serves a guiding function. In addition, unevenness or complex shapes on the surface of the strip may cause solution residue. This residual solution is blown into the recovery tank by the airflow output from the nozzle of the bamboo joint air tube. In this process, the amount of water adhering to the electroplating strip is reduced, which saves electroplating solution to a certain extent and thus reduces production costs.

[0032] Although the technical solutions according to the present invention have been described with reference to several different embodiments, aspects and features, it is not intended to limit the scope of the present invention, but modifications thereof are included within the broad scope of the foregoing disclosure, drawings and claims.
