Furthermore, some stripping methods can have adverse environmental impacts during use. Furthermore, in most existing stripping methods, the metal ion concentration in the stripping solution is high after a period of stripping. This metal ion concentration affects the stripping efficiency of the metal coating on the conductive clip, and excessively high metal ion concentrations inhibit the reaction between the stripping solution and the metal coating.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0025] As mentioned in the background, most existing stripping solutions have a high concentration of metal ions after a period of stripping workpieces. This metal ion concentration affects the efficiency of stripping the metal coating on the workpiece. Excessively high metal ion concentrations inhibit the reaction between the stripping solution and the metal coating. To address this issue, the present invention provides a stripping device and water electroplating equipment. The stripping device includes an electrolytic component that electrolyzes the stripping solution after a period of stripping, reducing the copper ion concentration in the stripping solution and improving its efficiency in stripping the copper coating on the workpiece. The present invention's stripping device is described in detail below, in conjunction with the accompanying drawings.

[0026] See also Figure 1 As shown, according to an embodiment of the present invention, a stripping device is provided. The stripping device is used to strip the copper layer on a workpiece 40 that is circulated and moves after the coating process. Specifically, the stripping device includes: a liquid storage mechanism and an electrolytic assembly 20.

[0027] In this embodiment, the liquid storage mechanism includes a liquid storage tank 10, which is used to store the peeling liquid 11; the electrolytic assembly 20 includes a power supply (not shown in the figure) connected to the same electrical circuit, an anode pole 21 and a cathode pole 22, and the ends of the anode pole 21 and the cathode pole 22 are used to be immersed in the peeling liquid 11.

[0028] In this embodiment, a liquid storage tank 10 is used to store the peeling liquid 11, and an electrolytic component 20 is provided in the liquid storage tank 10; the electrolytic component 20 includes a power supply, an anode pole 21 and a cathode pole 22 connected to the same electrical circuit, and the ends of the anode pole 21 and the cathode pole 22 are immersed in the peeling liquid 11 to electrolyze the copper ions in the peeling liquid 11. Specifically, after the peeling liquid 11 peels the workpiece 40 for a long time, the concentration of copper ions in the peeling liquid 11 increases, and the peeling efficiency of the copper layer on the workpiece 40 decreases. When the electrolytic component 20 is started, the copper ions in the peeling liquid 11 can be electrolyzed to reduce the concentration of copper ions in the peeling liquid 11, thereby improving the peeling efficiency of the copper layer on the workpiece 40 by the peeling liquid 11. The specific principle of electrolysis is: the anode pole 21 is used to transfer current to the peeling liquid 11, so that the copper sulfate (CuSO4) in the peeling liquid 11 is decomposed into copper ions (Cu 2 + ) and sulfate (SO4 2- ), the copper ions obtain electrons (e) on the cathode and are reduced to metallic copper, and are deposited on the cathode; thereby reducing the copper ion concentration in the stripping solution 11, reducing the inhibitory effect of high-concentration copper ions on stripping, and thus improving the stripping efficiency of the stripping solution 11 on the copper layer on the workpiece 40.

[0029] That is to say, this embodiment sets an electrolytic component 20 in the liquid storage tank 10 to electrolyze the high concentration of copper ions in the stripping liquid 11, thereby achieving the effect of reducing the concentration of copper ions, thereby ensuring the concentration of copper ions in the stripping liquid 11 and improving the efficiency of the stripping liquid 11 in removing the copper layer on the workpiece 40.

[0030] Furthermore, the liquid reservoir 10 includes a first liquid reservoir 101 and a second liquid reservoir 102. Among them, the first liquid reservoir 101 is used to peel the copper layer on the workpiece 40, and the electrolysis component 20 is arranged in the second liquid reservoir 102. The peeling process and the electrolysis process are respectively arranged in the corresponding liquid reservoir 10, thereby avoiding the conflict between peeling and electrolysis. In this embodiment, the workpiece 40 itself is charged. If the electrolysis component 20 is also arranged in the first liquid reservoir 101, the anode electrode 21 and the cathode electrode 22 will occupy the space of the peeling liquid 11 in the first liquid reservoir 101, and will also have an adverse effect on the peeling of the copper layer on the workpiece 40. Therefore, the second liquid reservoir 102 is provided for electrolysis, and the first liquid reservoir 101 and the second liquid reservoir 102 are connected through the conveying component 30. In other words, the conveying assembly 30 conveys the stripping liquid 11 in the first liquid reservoir 101 to the second liquid reservoir 102, or conveys the stripping liquid 11 in the second liquid reservoir 102 to the first liquid reservoir 101. The arrangement of the conveying assembly 30 in this embodiment enables the first liquid reservoir 101 and the second liquid reservoir 102 to be connected, thereby realizing the circulation of the stripping liquid 11 in the two liquid reservoirs 10, ensuring the concentration of the stripping liquid 11 and achieving efficient stripping of the copper layer on the workpiece 40.

[0031] like Figure 1 As shown, the second liquid storage tank 102 includes a main body 1021 and a cover plate 1022. A groove 10211 is provided on the main body 1021, and a cover plate 1022 is provided on the main body 1021, and the cover plate 1022 is covered at the notch of the groove 10211. Such a configuration can not only reduce the influence of other substances in the external environment on the concentration or composition of the peeling liquid 11, but also facilitate the installation of the electrolytic component 20 at the second liquid storage tank 102, avoid the pole falling when the electrolytic component 20 electrolyzes the peeling liquid 11, and reduce the occurrence of reduced work efficiency. Specifically, the anode pole 21 and the cathode pole 22 of the electrolytic component 20 are fixedly mounted on the cover plate 1022, and along the height direction of the second liquid storage tank 102 (i.e. Figure 1 Specifically, two positioning grooves 10221 are provided on the cover plate 1022. The two positioning grooves 10221 extend along the length direction of the second liquid storage tank 102 (i.e. Figure 1 The anode and cathode electrodes 21 and 22 are arranged sequentially (in the x-direction in FIG. 1 ). The positioning grooves 10221 facilitate the passage of the two electrodes through the cover plate 1022. Corresponding raised positioning blocks 23 are provided on the anode and cathode electrodes 21 and 22. When the anode and cathode electrodes 21 and 22 pass through the cover plate 1022 and enter the second liquid storage tank 102, the positioning blocks 23 are secured to the positioning grooves 10221, thereby achieving detachable fastening between the anode and cathode electrodes 21 and 22 and the cover plate 1022, thereby improving the operational stability of the electrolytic assembly 20.

[0032] Furthermore, the conveying assembly 30 includes a first conveying component 31 and a second conveying component 32. Specifically, the first conveying component 31 conveys the stripping liquid 11 in the second liquid reservoir 102 to the first liquid reservoir 101, while the second conveying component 32 conveys the stripping liquid 11 in the first liquid reservoir 101 to the second liquid reservoir 102. In this embodiment, when the copper ion concentration in the stripping liquid 11 in the first liquid reservoir 101 is too high, the second conveying component 32 conveys the stripping liquid 11 in the first liquid reservoir 101 to the second liquid reservoir 102 for electrolysis to reduce the copper ion concentration in the stripping liquid 11. When the volume of the stripping liquid 11 in the first liquid reservoir 101 falls below a set liquid level, the first conveying component 31 conveys the electrolyzed stripping liquid 11 in the second liquid reservoir 102 to the first liquid reservoir 101, where the stripping liquid 11 continues to strip the copper layer on the workpiece 40. The communication of the conveying assembly 30 realizes the recycling of the stripping liquid 11 in the two liquid storage tanks 10 and enables efficient stripping of the copper layer on the workpiece 40 .

[0033] Furthermore, the first conveying component 31 includes a first conveying pipe 311 and a first pump body 312. With this arrangement, when the peeling liquid 11 in the second liquid reservoir 102 is conveyed to the first liquid reservoir 101, the first pump body 312 provides power to achieve liquid conveyance. In this embodiment, the position of the first liquid reservoir 101 can be set higher than the second liquid reservoir 102, or lower than the second liquid reservoir 102. In actual operation, it is determined according to the actual conditions of the site. In this embodiment, it is preferred to set the position of the first liquid reservoir 101 higher than the second liquid reservoir 102; since the position of the second liquid reservoir 102 is lower than that of the first liquid reservoir 101, liquid conveyance cannot be achieved by gravity, and external power is required. Therefore, the first pump body 312 is provided on the first conveying pipe 311. The first delivery pipe 311 includes a first end 3111 and a second end 3112, wherein the first end 3111 of the first delivery pipe 311 is connected to the second liquid storage tank 102, which is conducive to liquid absorption; the port of the second end 3112 is connected to the first liquid storage tank 101 and is arranged toward the surface of the workpiece 40, which can not only realize the delivery of the stripping liquid 11, but also facilitate the reflux liquid to impact the copper layer deposited on the workpiece 40, thereby enhancing the stripping effect and further improving the stripping efficiency.

[0034] Furthermore, the second conveying member 32 includes a second conveying pipe 321. Along the height direction of the first liquid storage tank 101, the first end 3211 of the second conveying pipe 321 is connected to the second liquid storage tank 102, which is conducive to the peeling liquid 11 flowing out of the first liquid storage tank 101 and entering the second liquid storage tank 102; the connection point where the second end 3212 of the second conveying pipe 321 is connected to the first liquid storage tank 101 is close to the bottom of the first liquid storage tank 101. Figure 1As shown in FIG, the first liquid reservoir 101 is positioned higher than the second liquid reservoir 102. In this way, when the peeling liquid 11 in the first liquid reservoir 101 is transferred to the second liquid reservoir 102, no external power is required, and the peeling liquid 11 in the first liquid reservoir 101 is transferred to the second liquid reservoir 102 by relying on gravity.

[0035] Furthermore, in this embodiment, a second pump body 322 may be provided on the second delivery pipe 321. In this embodiment, the provision of the second pump body 322 improves the delivery efficiency of the peeling liquid 11. Furthermore, when the position between the second liquid reservoir 102 and the first liquid reservoir 101 changes, the second pump body 322 can be activated to deliver the peeling liquid 11, thereby facilitating the normal operation of the peeling device.

[0036] In this embodiment, the cathode electrode 22 is a pure copper electrode. With this arrangement, after the stripping solution 11 is electrolyzed, copper ions are deposited on the cathode electrode 22, and copper can be recovered without further separation. In copper smelting, electrolysis is used for two purposes: (1) to extract copper from a copper-containing solution; and (2) to purify copper from crude copper, that is, to separate copper from crude copper containing impurities. In this embodiment, the main purpose is to extract copper from a copper-containing solution. This electrolysis process is called electrolytic deposition. This avoids the influence of the introduction of new copper ions from the electrode on the copper ion concentration in the stripping solution 11. Therefore, the anode electrode 21 can be an insoluble electrode. Specifically, insoluble anode electrodes include graphite electrodes, lead dioxide electrodes (PbO2 metal electrodes, PbO2 / plastic electrodes, PbO2 / ceramic electrodes, PbO2 / graphite electrodes, etc.), titanium anode metal oxide coated electrodes, etc. In actual production processes, any one of them can be used.

[0037] Furthermore, the shapes of the anode pole 21 and the cathode pole 22 can be cylindrical, mesh-shaped, ring-shaped, or lath-shaped, etc. In this embodiment, the shapes of the anode pole 21 and the cathode pole 22 are preferably set to be cylindrical, so that the processing of the positioning groove 10221 arranged on the cover plate 1022 is relatively simple, thereby improving work efficiency.

[0038] According to the above embodiments, the peeling and hanging device of the present invention can at least achieve the following technical effects:

[0039] (1) The utility model separates electrolysis and stripping by providing a first liquid storage tank and a second liquid storage tank, thereby reducing the influence of the energized pole during electrolysis on the stripping of the workpiece, ensuring that the concentration of copper ions in the stripping solution is within an appropriate range, realizing the recycling of the stripping solution, and improving the stripping efficiency;

[0040] (2) The present invention uses pure copper as the cathode pole and an insoluble pole as the anode pole, and copper ions are deposited on the cathode pole, so there is no need for special separation when the copper is subsequently recovered;

[0041] (3) The present invention provides a cover plate on the second liquid storage tank and provides a positioning groove on the cover plate, so that the anode pole and the cathode pole are detachably fixed to the cover plate;

[0042] (4) The utility model connects the second end of the first conveying pipe with the first liquid storage tank and sets it toward the surface of the workpiece, and sets a first pump body on the first conveying pipe, which not only can realize the delivery of the stripping liquid, but also can impact the deposited copper on the workpiece, thereby enhancing the stripping effect and improving the stripping efficiency.

[0043] Combine Figure 1 As shown, the utility model also provides a water electroplating device, which includes the above-mentioned stripping device. When the conductive film is subjected to water electroplating, the water electroplating device uses the workpiece 40 to clamp the film for electroplating. The workpiece 40 will inevitably come into contact with the plating solution, which will cause the metal ions in the plating solution to be deposited on the workpiece 40, eventually forming larger protruding particles or copper layers, and then causing scratches, punctures, and even film breakage to the electroplated film, affecting the final product quality. Installing the above-mentioned stripping device on the water electroplating device can not only realize the stripping of the copper layer on the workpiece 40 and realize the recycling of the workpiece 40, but also reduce the influence of the copper layer on the workpiece 40 on the conductive film during the water electroplating process. This embodiment improves the stripping efficiency of the copper layer on the workpiece 40 by arranging the stripping device on the water electroplating device, ensures the orderly progress of the water electroplating process, and improves the quality of the conductive film.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0045] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
