[0002] During the conductive film water electroplating process, it is easy for a coating to be deposited on the supporting conductive clip. The conductive clip needs to be used repeatedly, so the coating needs to be completely stripped off.

[0003] Currently, the main methods for stripping raised particles or copper spikes from the surface of conductive clips in the existing technology include electrolytic stripping and chemical stripping. However, the electrolytic stripping method in the existing technology is complex and costly. In the chemical stripping method, the stripping solution can cause severe corrosion to the conductive clip, making it unreusable. In addition, some stripping methods can have adverse environmental impacts during use. Moreover, in most existing stripping methods, after a period of stripping, the metal ion concentration in the stripping solution is high. This metal ion concentration affects the stripping efficiency of the metal coating on the conductive clip. When the metal ion concentration is too high, it inhibits the reaction between the stripping solution and the metal coating. Utility Model Content

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0026] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. 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.

[0027] As mentioned in the background art, most prior art stripping methods result in a high concentration of metal ions in the stripping solution after a period of stripping. This metal ion concentration affects the stripping efficiency of the metal coating on the conductive clip. Excessively high metal ion concentrations inhibit the reaction between the stripping solution and the metal coating. To this end, the present invention provides a stripping device and water electroplating equipment. The stripping device includes an electrolytic component and a control component, which are electrically connected to the control component. The electrolytic component is controlled to electrolyze the copper ions in the stripping solution based on a signal transmitted by a first detection element in the control component, thereby reducing the concentration of copper ions in the stripping solution and improving the stripping efficiency of the stripping solution on the copper layer on the workpiece. The present invention's stripping device will be described in detail below in conjunction with the accompanying drawings.

[0028] 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, an electrolytic component 20, and a control component.

[0029] In this embodiment, the liquid storage mechanism includes a liquid storage tank 10, which is used to store the peeling liquid 11; the electrolytic component 20 includes a power supply (not shown in the figure) connected to the first electrical circuit, an anode electrode 21, a cathode electrode 22 and a control switch 24, the ends of the anode electrode 21 and the cathode electrode 22 are used to be immersed in the peeling liquid 11, and the control switch 24 is used to control the on and off of the first electrical circuit; the control component includes a first detection element 51 and a controller 54, the first detection element 51 is arranged in the liquid storage tank 10 for detecting the copper ion concentration in the peeling liquid 11, and the controller 54 is electrically connected to the first detection element 51 and the control switch 24 respectively, and the controller 54 is at least used to control the on and off of the control switch 24 according to the signal transmitted by the first detection element 51.

[0030] In this embodiment, a liquid reservoir 10 is provided for storing the peeling liquid 11, and an electrolytic assembly 20 is disposed within the liquid reservoir 10. The electrolytic assembly 20 includes an anode electrode 21, a cathode electrode 22, and a control switch 24. The ends of the anode electrode 21 and the cathode electrode 22 are immersed in the peeling liquid 11, which facilitates the electrolysis of the copper ions in the peeling liquid 11. The control switch 24 is used to control the first electrical circuit to enable and disable the first electrical circuit. Optionally, the control switch 24 can be a relay. The control assembly is connected to the second electrical circuit and includes a first detection element 51 and a controller 54. The first detection element 51 is provided to monitor the copper ion concentration in the peeling liquid 11 in real time. Based on the signal fed back by the first detection element 51, the controller 54 controls the electrolytic assembly 20 to electrolyze or stop the copper ions in the peeling liquid 11. This arrangement not only realizes the automatic monitoring of the copper ion concentration in the stripping solution 11 and the automatic electrolysis, thus reducing manual operations, but also improves the stripping efficiency of the stripping solution 11 on the copper layer on the workpiece 40 .

[0031] That is to say, this embodiment sets an electrolytic component 20 and a control component in the liquid storage tank 10. Among them, the first detection element 51 in the control component realizes real-time monitoring of the copper ion concentration in the stripping liquid 11. When the copper ion concentration is higher than the maximum value of the set value, the controller 54 controls the electrolytic component 20 to electrolyze the copper ions in the stripping liquid 11 to reduce the concentration of the copper ions, thereby improving the stripping efficiency of the stripping liquid 11 on the copper layer on the workpiece 40. When the copper ion concentration after electrolysis is lower than the minimum value of the set value, the controller 54 controls the electrolytic component 20 to cut off the power, stop electrolyzing the copper ions in the stripping liquid 11, and ensure the activity of the stripping liquid 11. This embodiment ensures the copper ion concentration in the stripping liquid 11 and improves the stripping efficiency of the stripping liquid 11 on the copper layer on the workpiece 40 by setting the electrolytic component 20 and the control component in the first liquid storage tank 10, and also realizes automatic control, reduces manual operation, and improves work efficiency.

[0032] 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 conflicting effects of 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 not only occupy the space of the peeling liquid 11 in the first liquid reservoir 101, but 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. Specifically, the conveying assembly 30 conveys the peeling liquid 11 in the first liquid reservoir 101 to the second liquid reservoir 102, or conveys the peeling 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 peeling liquid 11 in the two liquid reservoirs 10, ensuring the concentration of the peeling liquid 11 and achieving efficient peeling.

[0033] Furthermore, the conveying assembly 30 includes a first conveying component 31. Specifically, the first conveying component 31 comprises a first conveying pipe 311 and a first pump 312. This arrangement allows the first pump 312 to provide power to transport the peeling liquid 11 from the second liquid reservoir 102 to the first liquid reservoir 101. In this embodiment, the first liquid reservoir 101 can be positioned higher or lower than the second liquid reservoir 102, depending on the specific site conditions. Figure 1 The figure shows a case where the position of the first liquid reservoir 101 is set 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 transportation cannot be achieved by gravity and requires external power. Therefore, a first pump body 312 is provided on the first delivery pipe 311. In addition, 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 reservoir 102, which is conducive to liquid suction; the port of the second end 3112 is connected to the first liquid reservoir 101 and is arranged toward the surface of the workpiece 40, which not only realizes the transportation of the stripping liquid 11, but also facilitates the impact of the reflux liquid on the copper layer deposited on the workpiece 40, thereby enhancing the effect of stripping the copper layer and further improving the stripping efficiency.

[0034] Furthermore, the conveying assembly 30 also includes a second conveying component 32. The second conveying component 32 includes a second conveying pipe 321 and a second pump body 322, with the second pump body 322 being disposed on the second conveying pipe 321. With this arrangement, if the first and second liquid reservoirs 101, 102 are located at the same horizontal position during actual construction due to geographical constraints, relying on gravity to transport the peeling liquid 11 presents a certain degree of difficulty. In this case, a second pump body 322 can be provided to provide power. Furthermore, in this case, after the peeling liquid 11 in the second liquid reservoir 102 undergoes electrolysis, the copper ion concentration in the peeling liquid 11 decreases, necessitating the transfer of the peeling liquid 11 from the first liquid reservoir 101 to the second liquid reservoir 102. This may require a significant amount of time to transport the peeling liquid 11 by gravity. In this embodiment, the second pump body 322 is provided to efficiently transport the stripping liquid 11, allowing for rapid circulation of the stripping liquid 11 within the first and second reservoirs 101, 102, thereby improving the efficiency of the stripping liquid 11 in stripping the copper layer from the workpiece 40. Along the height of the first reservoir 101, the first end 3211 of the second delivery tube 321 communicates with the second reservoir 102, while the second end 3212 of the second delivery tube 321 communicates with the first reservoir 101 near the bottom of the first reservoir 101. This arrangement eliminates the need for external power; gravity alone transfers the stripping liquid 11 from the first reservoir 101 to the second reservoir 102.

[0035] like Figure 1As shown, the peeling device in this embodiment further includes a second detection element 52. The copper ion concentration in the peeling liquid 11 affects the peeling efficiency. The second detection element 52 is disposed within the first liquid reservoir 101 and is configured to detect the copper ion concentration of the peeling liquid 11 within the first liquid reservoir 101. The second detection element 52 is electrically connected to a controller 54, which controls the second pump 322 based on the signal transmitted by the second detection element 52. Specifically, when the second detection element 52 detects that the copper ion concentration in the peeling liquid 11 exceeds a set maximum value, the controller 54, which is electrically connected to the second detection element 52, immediately activates the second pump 322 to transfer the peeling liquid 11 from the first liquid reservoir 101 to the second liquid reservoir 102. When the first detection element 51 within the second liquid reservoir 102 detects that the copper ion concentration exceeds a set maximum value, the controller 54 controls the control switch 24 to electrolyze the copper ions in the peeling liquid 11. Furthermore, if the volume of the solution in the first liquid reservoir 101 falls below a predetermined level, the controller 54 can control the first pump 312 to transfer the electrolyzed stripping solution 11 in the second liquid reservoir 102 to the first liquid reservoir 101. In this embodiment, the controller 54 is electrically connected to the pump, which facilitates controlling the pump to improve the delivery or circulation efficiency, thereby rapidly circulating the stripping solution 11 in the second liquid reservoir 102, thereby reducing the copper ion concentration in the stripping solution 11 in the first liquid reservoir 101 and improving the stripping efficiency.

[0036] In this embodiment, the first detection element 51 is disposed in the second liquid reservoir 102. The copper ion concentration in the stripping liquid 11 in the second liquid reservoir 102 is monitored in real time by the first detection element 51. When the copper ion concentration is lower than a certain minimum set value, the controller 54 controls the electrolytic assembly 20 to stop working to prevent the stripping liquid 11 from losing its activity. The controller 54 also controls the first pump body 312. When the volume of the stripping liquid 11 in the first liquid reservoir 101 decreases, the first pump body 312 is started to transport the stripping liquid 11 in the second liquid reservoir 102 to the first liquid reservoir 101. It is worth noting that in this embodiment, both the first liquid reservoir 101 and the second liquid reservoir 102 are provided with liquid level gauges (not shown in the figure). When the stripping liquid 11 in one tank reaches the maximum liquid level, the liquid is stopped from being pumped in or the conveying assembly 30 is started to transport the stripping liquid 11 to the other liquid reservoir 10.

[0037] Furthermore, the second liquid storage tank 102 includes a main body 1021 and a cover plate 1022, and a groove 10211 is provided on the main body 1021, and a cover plate 1022 is also provided on the main body 1021, and the cover plate 1022 is covered at the notch of the groove 10211. Such a setting 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. 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 in sequence (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 fixed to the positioning grooves 10221, thereby removably securing the anode and cathode electrodes 21 and 22 to the cover plate 1022 and improving the operational stability of the electrolytic assembly 20.

[0038] Furthermore, a connector 60 is provided between the cover plate 1022 and the first detection element 51. One end of the connector 60 is fixed to the cover plate 1022, and the other end of the connector 60 is connected to the first detection element 51. The first detection element 51 is provided in the peeling liquid 11. Optionally, the first detection element 51 can be provided at the bottom of the second liquid storage tank 102, or it can be provided in the second liquid storage tank 102 without touching the bottom of the second liquid storage tank 102 (i.e., the first detection element 51 is suspended in the peeling liquid 11). In this embodiment, as Figure 1 As shown, the first detection element 51 is preferably suspended in the peeling liquid 11. In this way, the first detection element 51 can swing in the second liquid reservoir 102 instead of being fixed in a certain position, so that the copper ion concentration in the second liquid reservoir 102 can be more accurately and objectively reflected, thereby facilitating precise control.

[0039] In this embodiment, the stripping device also includes a temperature control component (not shown in the figure). During actual operation, the temperature of the stripping liquid 11 will affect the stripping efficiency of the copper layer on the workpiece 40 by the stripping liquid 11. The temperature control component can be set to realize real-time monitoring of the stripping liquid 11. Specifically, the temperature control component is arranged in the first liquid storage tank 101. The temperature control component includes a temperature sensor (not shown in the figure) and a heating element (not shown in the figure), wherein the temperature sensor is used to monitor the temperature of the stripping liquid 11 in the first liquid storage tank 101, and the heating element is used to heat the stripping liquid 11. Specifically, the temperature sensor and the heating element are both electrically connected to the controller 54. When the temperature sensor detects that the temperature of the stripping liquid 11 is lower than the set value, the controller 54 controls the heating element according to the signal transmitted by the temperature sensor, and starts the heating element to heat the stripping liquid 11; when the temperature reaches the set value, the controller 54 controls the heating element to stop heating the stripping liquid 11. Monitoring the temperature of the stripping liquid 11 is beneficial to maintaining the temperature of the stripping liquid 11 within an appropriate range, thereby improving the stripping efficiency of the stripping liquid 11 on the copper layer on the workpiece 40 .

[0040] In this embodiment, a hollow frame 53 is provided on the periphery of the first detection element 51 and the second detection element 52. Such a configuration can reduce the collision between the first detection element 51 or the second detection element 52 and the side wall or bottom of the liquid storage tank 10, avoid damage to the relevant sensing components of the detection element, and ensure the normal operation of the detection element.

[0041] It can be seen from the above embodiments that the peeling and hanging device of the utility model can at least achieve the following technical effects:

[0042] (1) The utility model separates the stripping and electrolysis processes by providing a first liquid storage tank and a second liquid storage tank, thereby reducing the mutual influence between the two processes and improving the stripping effect of the copper layer on the workpiece;

[0043] (2) The utility model sets an electrolytic component and a control component, and the control component includes a controller, a first detection element and a second detection element. The first detection element monitors the copper ion concentration of the stripping liquid in the second liquid storage tank in real time. According to the monitoring feedback signal, the controller controls the electrolytic component to perform electrolysis; the second detection element monitors the copper ion concentration of the stripping liquid in the first liquid storage tank in real time to ensure the copper ion concentration in the stripping liquid and improve the stripping efficiency;

[0044] (3) The utility model is provided with a control component, which is electrically connected to the first pump body and the second pump body. According to the signal fed back by the detection element, the controller is electrically connected to the pump body to improve the delivery or circulation efficiency of the stripping liquid, and the stripping liquid in the second liquid storage tank is quickly circulated to reduce the copper ion concentration in the stripping liquid in the first liquid storage tank, thereby improving the stripping efficiency;

[0045] (4) The present invention sets a temperature control component in the first liquid storage tank to keep the temperature of the peeling liquid within the optimal range, which is beneficial to improving the peeling efficiency.

[0046] Combine Figure 1 As shown, the present invention 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 a workpiece 40 to clamp the film for electroplating. The workpiece 40 will inevitably come into contact with the plating solution. This will cause the metal ions in the plating solution to deposit on the surface of the workpiece 40, eventually forming large raised particles or copper layers, which in turn cause scratches, punctures, and even film breakage of the electroplated film, affecting the final product quality. Installing the above-mentioned stripping device on the water electroplating device can not only achieve the stripping of the copper layer on the workpiece 40, but also the recycling of the workpiece 40.

[0047] Specifically, a control component is provided that is electrically connected to the electrolysis component 20, the conveying component 30, and the temperature control component. This allows monitoring of the temperature of the stripping liquid 11 during the stripping process, and heating the stripping liquid 11 through a heating element to ensure that the temperature of the stripping liquid 11 is within an appropriate range, thereby improving the stripping effect. Furthermore, the copper ion concentration in the stripping liquid 11 within the liquid reservoir 10 is monitored in real time. When the copper ion concentration in the stripping liquid 11 is too high, the conveying component 30 is activated to transport the stripping liquid 11 within the first liquid reservoir 101 to the second liquid reservoir 102, and electrolysis is performed on the copper ions in the stripping liquid 11 to reduce the copper ion concentration. After electrolysis, the stripping liquid 11 with a reduced copper ion concentration is transported to the first liquid reservoir 101 through the conveying component 30, thereby achieving circulation of the stripping liquid 11 within the two liquid reservoirs 10. This arrangement can not only ensure the activity of the stripping liquid 11, but also efficiently strip the copper layer on the workpiece 40, reducing the impact of the workpiece 40 on the quality of the conductive film during the water electroplating process and improving the quality of the conductive film.

[0048] 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.

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.
