Description

Technical Field

[0001] The present application relates to the field of electroplating technology, and in particular to a stepped continuous electroplating tank system. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] The patent document with publication number CN109208063A discloses a continuous electroplating tank, including a first electroplating tank, a cleaning tank, a drying tank and a second electroplating tank. The components after electroplating in the first electroplating tank are transported to the cleaning tank, the drying tank and the second electroplating tank in sequence under the action of a moving crossbeam, thereby realizing continuous electroplating of the product, which has certain positive significance. However, since the first electroplating tank is provided with a plating liquid, the entire component needs to be transported, lowered, raised and then transported alternately during the continuous electroplating process, that is, the transportation of the product requires intermittent transportation, which affects the efficiency; even if the time consumed to achieve electroplating is greater than the process of alternating motion, the mechanism for realizing the above motion will be relatively complex and costly, so it is necessary to provide a continuous electroplating tank system.

DETAILED DESCRIPTION

[0022] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0023] like Figure 1-4 As shown, a stepped continuous electroplating tank system includes a plating tank module 1, which includes a first plating tank 10, a cleaning tank 11, a drying tank 12 and a second plating tank 13 in sequence; connecting holes 4 for the product 6 to be plated to pass through are provided between the first plating tank 10 and the cleaning tank 11, between the cleaning tank 11 and the drying tank 12, and between the drying tank 12 and the second plating tank 13, and a rotating roller 40 is rotatably provided on the connecting hole 4; auxiliary conveying rollers are rotatably provided in the first plating tank 10 and the second plating tank 13, and the lower edge of the auxiliary conveying roller is located below the liquid surface of the electroplating solution.

[0024] The first plating tank 10 , the cleaning tank 11 , the drying tank 12 and the second plating tank 13 are separated from each other by a partition plate 8 , and the connecting hole 4 is specifically provided on the partition plate 8 .

[0025] The rotating roller 40 disposed on the connecting hole 4 is used to assist in conveying the product 6 to be plated, thereby preventing the product 6 to be plated from being scratched against the edge of the connecting hole 4 .

[0026] An auxiliary conveying roller is provided in the first plating tank 10, and is used to assist in the conveyance of the product 6 to be plated. The lower edge of the auxiliary conveying roller is located below the surface of the electroplating liquid. In other embodiments, the entire auxiliary conveying roller can be immersed in the electroplating liquid to ensure that the product 6 to be plated is pressed into the interior of the electroplating liquid to achieve electroplating.

[0027] The first plating tank 10 and the second plating tank 13 are mainly used for electroplating products. The cleaning tank 11 is used to clean the plating solution in the first plating tank 10 attached to the product 6 to be plated. The drying tank 12 is used to dry the cleaned product 6 to be plated, thereby preventing the plating solution in the first plating tank 10 remaining on the product 6 to be plated from "polluting" the plating solution in the second plating tank 13, thereby affecting the effect of continuous electroplating.

[0028] Under the action of the auxiliary conveying rollers, the product to be plated 6 can move continuously without intermittent movement as in traditional devices. This not only greatly improves the efficiency of continuous electroplating, but also simplifies the structure of the entire mechanism for conveying the product to be plated 6, making it easier for early installation and later maintenance, while also reducing costs.

[0029] In some further embodiments, the auxiliary conveying roller includes a first rotating shaft 2 and a rotating column 20, and the rotating column 20 is rotatably arranged on a group of side walls of the first plating tank 10 through the first rotating shaft 2, and the axis of the first rotating shaft 2 is parallel to the axis of the rotating roller 40.

[0030] like Figure 1 As shown, the axial direction of the first rotating shaft 2 is arranged front to back and parallel to the rotating roller 40 .

[0031] During the conveying process, the product 6 to be plated will synchronously drive the rotating column 20 to rotate, and at the same time, the product 6 to be plated will be pressed into the electroplating solution by the rotating column 20 for electroplating.

[0032] In some further embodiments, a limiting groove 21 is provided on the outer peripheral wall of the rotating column 20 , and the width of the limiting groove 21 is consistent with the width of the product 6 to be plated.

[0033] The limiting groove 21 is arranged on the outer peripheral wall of the rotating column 20 to ensure the stability of the product 6 to be plated during the transportation process and to avoid axial movement along the first rotating shaft 2.

[0034] The limiting groove 21 is consistent with the width of the product 6 to be plated, that is, they are adapted to each other.

[0035] In some further embodiments, a rotating wheel group is provided in the cleaning tank 11 and the drying tank 12, and the rotating wheel group includes a second rotating shaft 3, a turntable 30 and a plurality of supporting shafts 31. There are two turntables 30, and the two turntables 30 are axially spaced apart on the second rotating shaft 3. The plurality of supporting shafts 31 are circumferentially spaced apart along the outer peripheral wall of the second rotating shaft 3, and one end of the plurality of supporting shafts 31 is connected to the side wall of one of the turntables 30, and the other end is connected to the side wall of another turntable 30.

[0036] The rotating wheel column has two functions. One is to assist in the transportation of the product 6 to be plated, and it can also play a certain tensioning role on the product 6 to be plated. The other function is to increase the effective cleaning or drying length of the product 6 to be plated in the cleaning tank 11 and the drying tank 12, thereby ensuring the cleaning effect or drying effect.

[0037] Under the action of several supporting shafts 31, the entire rotating wheel assembly presents a frame structure, which can realize the cleaning and drying of the product 6 to be plated at multiple angles.

[0038] In some further embodiments, a shower head is provided in the cleaning tank 11 , the outlet of the shower head faces the axis of the second rotating shaft 3 , and an air shower head is provided in the drying tank 12 .

[0039] The spray head and air shower head are used for cleaning and drying the products to be plated respectively 6.

[0040] Sprinkler heads and air shower heads are widely used in the industry and are prior art. Their structures and principles will not be described in detail in this embodiment.

[0041] In some further embodiments, the number of the plating tank modules 1 is two, the two plating tank modules 1 are arranged axially at intervals along the first rotating shaft 2 , and one of the plating tank modules 1 is higher than the other plating tank module 1 .

[0042] The plating tank module 1 needs to be cleaned as a whole after being used a certain number of times or for a certain period of time. In order to avoid the waste caused by the need to clean multiple plating tank modules 1 separately, the heights of the two plating tank modules 1 are different. When cleaning, you can directly flush from the higher group of plating tank modules 1, so that the flushing water flows to the lower plating tank module 1 under the action of gravity for cleaning, thereby reducing the consumption of flushing water.

[0043] In some further embodiments, the first plating tank 10 , the cleaning tank 11 , the drying tank 12 , and the second plating tank 13 in the two plating tank modules 1 are connected to each other respectively.

[0044] Specifically, different tank flushing processes are not connected to each other to avoid secondary pollution; illustratively, they can be connected through the connecting channel 5.

[0045] In some further embodiments, a reflux pipe 7 is provided between the first plating tank 10 , the cleaning tank 11 , the drying tank 12 , and the second plating tank 13 in the two plating tank modules 1 .

[0046] When circulating flushing is required, the reflux of the cleaning water can be achieved through the reflux pipe 7. Specifically, a pump body 70 can be arranged on the reflux pipe 7 for reflux.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
