[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0023] like Figure 1 An automatic plating solution processing system 100 is shown. The automatic plating solution processing system 100 is used to process electroplating solution. The electroplating solution is used in the diamond wire production line. Since the electroplating solution needs to be electrolyzed after a certain production cycle, the electroplating solution can effectively remove impurity metal ions such as iron, copper, zinc, chromium, and lead in the electroplating solution through electrolysis. At the same time, particulate impurities in the electroplating solution are removed by filtering to reduce the stress value of the electroplating solution, so that the electroplating solution can meet the production and use requirements again, thereby realizing the repeated recycling of the electroplating solution. The present application realizes rapid electrolysis and filtration of the electroplating solution through the automatic plating solution processing system 100, which is beneficial to shorten the processing time of the electroplating solution, and further beneficial to improve the working efficiency of the automatic plating solution processing system 100. In order to clearly illustrate the technical solution of the application, it is also defined as follows: Figure 1In the present application, the length direction of the automatic plating liquid processing system 100 refers to the front-to-back direction, the width direction of the automatic plating liquid processing system 100 refers to the left-right direction, and the height direction of the automatic plating liquid processing system 100 refers to the up-down direction.

[0024] As an implementation method, the automatic plating solution treatment system 100 includes a used liquid recovery tank 11, an activated carbon tank 12, a filter press electrolysis assembly 13 and a used liquid storage tank 14. The used liquid recovery tank 11 is used to store the plating solution to be treated. The activated carbon tank 12 is connected to the used liquid recovery tank 11. The used liquid recovery tank 11 transports the plating solution to the activated carbon tank 12. The activated carbon tank 12 is used to adsorb impurities in the plating solution, thereby removing most of the large impurities, chemicals and odors in the plating solution. The filter press electrolysis assembly 13 is connected to the activated carbon tank 12. The activated carbon tank 12 transports the adsorbed plating solution to the filter press electrolysis assembly 13. The filter press electrolysis assembly 13 is used to filter and electrolyze the plating solution, so that the plating solution meets the production and use requirements again. The used liquid storage tank 14 is connected to the filter press electrolysis assembly 13. The filter press electrolysis assembly 13 transports the treated plating solution to the used liquid storage tank 14. The used liquid storage tank 14 is used to collect the treated plating solution. Through the above arrangement, the electroplating solution can be recycled, which is beneficial to increasing the service life of the electroplating solution, and the processing capacity of the automatic plating solution processing system 100 is relatively high, which is beneficial to improving the working efficiency of the automatic plating solution processing system 100.

[0025] like Figures 1 to 3As shown, in this embodiment, the automatic plating liquid processing system 100 also includes a liquid level detection component 15, a valve body component 16 and a control component 17. The liquid level detection component 15 is arranged in the activated carbon tank 12. The liquid level detection component 15 is used to detect the liquid level of the electroplating liquid to generate a feedback signal. The activated carbon tank 12 is connected to the filter press electrolysis component 13 through the valve body component 16, and the valve body component 16 is used to control the flow of the electroplating liquid. The control component 17 is electrically connected to the liquid level detection component 15 and the valve body component 16, and the control component 17 can control the opening or closing of the valve body component 16 according to the feedback signal. Specifically, the activated carbon tank 12 and the filter press electrolysis assembly 13 are responsible for different processing tasks, and the plating liquid needs to be processed by the activated carbon tank 12 and then transported to the filter press electrolysis assembly 13 through the valve body assembly 16. Since it takes a long time for the activated carbon tank 12 to process the plating liquid, in order to avoid the valve body assembly 16 and the filter press electrolysis assembly 13 from continuously operating, a liquid level detection assembly 15 is set in the activated carbon tank 12 to detect the liquid level of the plating liquid and form a feedback signal. After receiving the feedback signal, the control assembly 17 controls the valve body assembly 16 and the filter press electrolysis assembly 13 to start working. Through the above-mentioned setting, it is possible to avoid the activated carbon tank 12, the valve body assembly 16 and the filter press electrolysis assembly 13 working synchronously, which causes the valve body assembly 16 and / or the filter press electrolysis assembly 13 to run idle, so as to prevent the valve body assembly 16 and / or the filter press electrolysis assembly 13 from being damaged, thereby facilitating the service life of the valve body assembly 16 and the filter press electrolysis assembly 13, and further improving the service life of the automatic plating liquid processing system 100. At the same time, when a problem occurs in a processing link of the automatic plating solution processing system 100, the entire automatic plating solution processing system 100 can be avoided from being shut down, which is also beneficial to improving the processing speed of the automatic plating solution processing system 100, thereby improving the working efficiency of the automatic plating solution processing system 100. In addition, the activated carbon tank 12, the valve body assembly 16 and the filter press electrolysis assembly 13 can work as needed, thereby reducing the power loss of the activated carbon tank 12, the valve body assembly 16 and the filter press electrolysis assembly 13, thereby helping to reduce the energy consumption of the automatic plating solution processing system 100.

[0026] As an implementation method, the automatic plating solution treatment system 100 also includes a water circuit assembly 18, through which the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis assembly 13 and the old liquid storage tank 14 are sequentially connected, and the valve body assembly 16 is connected to the water circuit assembly 18. Specifically, the water circuit assembly 18 is composed of a plurality of pipelines, and the water circuit assembly 18 can be bent according to actual needs so that the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis assembly 13 and the old liquid storage tank 14 can be sequentially connected, wherein the valve body assembly 16 is composed of a plurality of valve bodies, each valve body corresponding to a pipeline setting, so that the valve body can control the flow of the electroplating solution in the pipeline, thereby facilitating the control of the working state of the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis assembly 13 and the old liquid storage tank 14, thereby improving the working efficiency of the automatic plating solution treatment system 100. It should be noted that the valve body assembly 16 can be a one-way valve or a solenoid valve.

[0027] As another implementation method, the valve body assembly 16 can also be integrated in the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis assembly 13 and the old liquid storage tank 14, so that the water path assembly 18 is connected to the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis assembly 13 and the old liquid storage tank 14 through the valve body assembly 16, thereby avoiding too many sections of the water path assembly 18 and increasing the difficulty of transfer, which is beneficial to improving the assembly efficiency of the automatic plating solution processing system 100.

[0028] like Figure 4As shown, as an implementation method, the filter press electrolysis assembly 13 includes a filter press device 131, a filter device 132 and an electrolysis device 133 connected in sequence, the filter press device 131 and the filter device 132 are connected through the valve body assembly 16, the filter device 132 and the electrolysis device 133 are connected through the valve body assembly 16, the filter press device 131 and the filter device 132 are both used to filter the electroplating liquid, and the electrolysis device 133 is used to electrolyze the electroplating liquid. Specifically, the main working principle of the filter press device 131 is to squeeze the electroplating liquid through high pressure so that the solid matter in the electroplating liquid is squeezed out. In the filter press device 131, there is a filter medium such as a filter cloth or filter paper. When the electroplating liquid is squeezed through this filter medium, the solid matter of the electroplating liquid will be left on the filter medium, thereby achieving solid-liquid separation. The filter press device 131 is generally suitable for treating liquids with higher concentrations and has a relatively large treatment capacity. Since the principle of the filter press device 131 is to use high-pressure extrusion, the treatment effect of the filter press device 131 is relatively good, but it also requires a higher operating pressure. Unlike the filter press 131, the filter 132 performs solid-liquid separation by filtering media. In the filter 132, the filtering media are usually various filter elements or filter bags, etc. When the liquid passes through these media, the solid matter will be intercepted and retained on the media, while the clear liquid can flow out through the media. The filter 132 is suitable for treating liquids with low concentrations, and its processing capacity is relatively small. The electrolytic device 133 is used to remove impurity metal ions such as iron, copper, zinc, chromium, and lead in the electroplating solution, and at the same time remove particulate impurities in the electroplating solution by filtering to reduce the stress value of the electroplating solution, so that the electroplating solution can meet the production and use requirements again. Through the above-mentioned settings, the electroplating solution is first filtered by the filter press 131 and changed from a high-concentration electroplating solution to a low-concentration electroplating solution, and then filtered by the filter 132 for the low-concentration electroplating solution, and finally the electrolytic separation of the electroplating solution is performed by the electrolytic device 133, so as to achieve rapid processing of the electroplating solution, which is conducive to improving the working efficiency of the automatic plating solution processing system 100.

[0029] Exemplarily, the activated carbon tank 12 is connected to the filter press device 131 and communicated through the valve body assembly 16, and the old liquid storage tank 14 is connected to the electrolysis device 133 and communicated through the valve body assembly 16, so that the activated carbon tank 12, the filter press device 131, the filter device 132, the electrolysis device 133 and the old liquid storage tank 14 are connected in sequence through the valve body assembly 16, thereby forming a complete processing flow, and the control component 17 controls the operation of the activated carbon tank 12, the filter press device 131, the filter device 132, the electrolysis device 133 and the old liquid storage tank 14 by manipulating the valve body assembly 16, which is beneficial to improve the control performance of the automatic plating solution treatment system 100.

[0030] Among them, the liquid level detection component 15 is also arranged in the old liquid storage tank 14, and the liquid level detection component 15 is used to detect the liquid level of the electroplating liquid in the old liquid storage tank 14 and generate a feedback signal. The control component 17 controls the opening or closing of the valve body component 16 between the electrolysis device 133 and the old liquid storage tank 14 according to the feedback signal. Specifically, the storage capacity of the old liquid storage tank 14 is limited. When the liquid level detection component 15 detects that there is too much electroplating liquid in the old liquid storage tank 14, the feedback signal can be transmitted to the control component 17, and the control component 17 closes the valve body component 16 between the electrolysis device 133 and the old liquid storage tank 14, which is beneficial to protect the old liquid storage tank 14, thereby improving the safety performance of the automatic plating liquid processing system 100.

[0031] like Figure 2 and Figure 3 As shown, as an implementation method, the liquid level detection component 15 includes a first detection member 151 and a second detection member 152, the activated carbon tank 12 and the old liquid storage tank 14 are both formed with a liquid storage space 101, the first detection member 151 and the second detection member 152 are both located in the liquid storage space 101, the first detection member 151 is arranged near the bottom of the liquid storage space 101, and the second detection member 152 is arranged near the top of the liquid storage space 101, and the first detection member 151 and the second detection member 152 are both used to detect the liquid level of the electroplating liquid to produce a feedback signal. Specifically, the activated carbon tank 12 and the old liquid storage tank 14 each include a heating member 102, a stirring member 103 and a driving member 104, the stirring member 103 is at least partially located in the liquid storage space 101, the driving member 104 is located at the upper end of the stirring member 103 and is transmission-connected to the stirring member 103, and the driving member 104 drives the stirring member 103 to rotate in the liquid storage space 101. More specifically, the control component 17 is also electrically connected to the driving member 104 and the heating member 102. When the liquid surface of the electroplating solution contacts the first detection member 151, the control component 17 drives the heating member 102, the stirring member 103 and the driving member 104 to start working at the same time. When the liquid surface of the electroplating solution contacts the second detection member 152, the control component 17 opens the valve body component 16 to transport the electroplating solution to the filter press 131. Through the above arrangement, the first detection member 151 and the second detection member 152 can keep the electroplating solution in the liquid storage space 101 within a reasonable range, which is conducive to improving the working performance of the automatic plating solution processing system 100. At the same time, the detection accuracy of the first detection member 151 and the second detection member 152 is high, which is also conducive to improving the detection capability of the automatic plating solution processing system 100.

[0032] It should be noted that, observing along the height direction of the automatic plating solution processing system 100, the heating element 102 is arranged around the stirring element 103. The heating element 102, the stirring element 103 and the driving element 104 can increase the processing speed of the plating solution, which is beneficial to improving the processing efficiency of the plating solution.

[0033] like Figure 5 As shown, as an implementation method, the automatic plating solution processing system 100 also includes a pump body component 19 electrically connected to the control component 17, and the pump body component 19 is distributed between the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis component 13 and the old liquid storage tank 14. The pump body component 19 is used to drive the plating solution to flow from the old liquid recovery tank 11 into the old liquid storage tank 14. Specifically, the pump body component 19 is used to drive the rapid flow of the plating solution, which is conducive to shortening the flow time of the plating solution between the old liquid recovery tank 11, the activated carbon tank 12, the filter press electrolysis component 13 and the old liquid storage tank 14, and further helps to improve the reaction speed of the automatic plating solution processing system 100.

[0034] As an implementation method, the automatic plating solution processing system 100 further includes an old liquid collection tank 20, and the old liquid storage tank 14 is connected to the old liquid storage tank 14 through a pump body assembly 19, and the pump body assembly 19 drives the plating liquid to flow from the old liquid storage tank 14 into the old liquid collection tank 20. Specifically, when the plating liquid in the old liquid storage tank 14 tends to be saturated, the plating liquid in the old liquid storage tank 14 can be transported to the old liquid collection tank 20 through the pump body assembly 19, so that the old liquid storage tank 14 can continuously store the plating liquid, thereby improving the working efficiency of the automatic plating solution processing system 100.

[0035] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
