Therefore, by arranging the first metal ion concentration detector 131 in the cleaning tank 110, the first metal ion concentration detector 131 can detect the metal ion concentration in the cleaning liquid in the cleaning tank 110, and can accurately control the opening or closing of the first control valve 141 according to the metal ion concentration, so that the situation that the cleaning liquid is directly discharged into the recovery tank 120 for ion concentration reduction treatment when the metal ion concentration in the cleaning liquid in the cleaning tank 110 is low is avoided, and the effects of reducing the frequency of the cleaning liquid treated by the recovery tank 120 and the recovery cost of the recovery tank 120 are achieved. The situation that the cleaning liquid cannot be discharged to the recovery tank 120 in time when the concentration of metal ions in the cleaning liquid in the cleaning tank 110 is high is avoided, and the cleaning effect of the conductive clip 200 is ensured. In addition, the recycling box 120 can perform ion concentration reduction treatment on the cleaning liquid discharged from the cleaning box 110, and the treated cleaning liquid can be continuously used for cleaning the conductive clip 200, so that the cleaning liquid can be recycled, and meanwhile, the cleaning liquid which is used for cleaning the conductive clip 200 can be prevented from being directly discharged, and therefore, resource waste and environmental pollution are reduced.
In addition, the above description shows that the cleaning tank 110 and the recovery tank 120 are connected by the first control valve 141, and the specific connection form of the first control valve 141 is explained as follows:
in a possible connection structure of the first control valve 141, when the first control valve 141 is a reversing valve, as shown in fig. 1, the first control valve 141 has a first position and a second position, when the first control valve 141 is in the first position, the cleaning liquid in the cleaning tank 110 can enter the recovery tank 120 through the first control valve 141, and when the first control valve 141 is in the second position, the cleaning liquid after being processed by the recovery tank 120 can enter the cleaning tank 110 through the first control valve 141. The specification of the direction valve is not limited, and the direction valve is, for example, a two-position two-way direction valve.
As shown in fig. 1, the power of the cleaning liquid entering the recovery tank 120 from the cleaning tank 110 through the first control valve 141 is a pressure difference, and the power of the cleaning liquid entering the cleaning tank 110 from the recovery tank 110 through the first control valve 141 is provided by the first suction pump 161, so that the cleaning liquid after being processed by the ion concentration reduction of the recovery tank 120 returns to the cleaning tank 110 for cleaning the conductive clip 200, thereby achieving the purpose of recycling the cleaning liquid. Of course, the power from the washing tank 110 to the recovery tank 120 and the cleaning liquid from the recovery tank 120 to the washing tank 110 are not limited to the above-described structure, and a bidirectional suction pump may be provided between the washing tank 110 and the recovery tank 120, which will not be described in detail.
Therefore, when the first control valve 141 is a reversing valve, the flow direction of the cleaning liquid in the cleaning tank and the cleaning liquid in the recovery tank can be changed by switching the working position of the first control valve 141, a plurality of openings do not need to be arranged on the cleaning tank and the recovery tank, and the structures of the cleaning tank and the recovery tank are simplified.
In another possible connection structure of the first control valve 141, the first control valve 141 is a one-way valve, as shown in fig. 2, the cleaning tank 110 has a waste liquid outlet 112 and a recovery inlet 111, the recovery tank 120 has an inlet and an outlet, the waste liquid outlet 112 communicates with the inlet of the recovery tank 120, the recovery inlet 111 communicates with the outlet of the recovery tank 120, the first control valve 141 is connected between the waste liquid outlet and the inlet of the recovery tank, and when the first control valve 141 is opened, the cleaning liquid in the cleaning tank can enter the recovery tank through the first control valve 141.
As shown in fig. 2, the cleaning liquid enters the recovery tank 120 through the waste liquid outlet 112 via the first control valve 141 at the inlet of the recovery tank 120, because the pressure surface in the cleaning tank 110 is higher than the liquid surface in the recovery tank 120, the cleaning liquid in the cleaning tank 110 enters the recovery tank 120 via a pressure difference, and because the outlet of the recovery tank 120 is connected to the recovery inlet 111, and the first suction pump 161 is connected between the outlet of the recovery tank 120 and the recovery inlet 111, the cleaning liquid in the recovery tank 120 is pumped into the cleaning tank 110 via the first suction pump 161, so that the cleaning liquid after being treated by the ion concentration reduction of the recovery tank 120 returns to the cleaning tank 110 for cleaning the conductive clip 200, thereby achieving the purpose of recycling the cleaning liquid.
Therefore, the waste liquid outlet 112 is communicated with the inlet of the recovery tank 120, and the recovery inlet 111 is communicated with the outlet of the recovery tank 120, so that the cleaning liquid flows from the cleaning tank 110 to the recovery tank 120 and from the recovery tank 120 to the cleaning tank 110 at the same time, and the cleaning liquid flows from the cleaning tank 110 to the recovery tank 120 and from the recovery tank 120 to the cleaning tank 110 sequentially, thereby improving the flexibility of the flow direction of the cleaning liquid.
Of course, the arrangement positions of the cleaning tank 110 and the recovery tank 120 are not limited to the above-described structure, and for example, the first control valve may be arranged between the outlet of the recovery tank 120 and the recovery inlet 111, which will not be described in detail.
Only the first control valve 141 is described below as a check valve:
the cleaning box 110 may be used as a cleaning tank for cleaning the conductive clip 200, or as a device for accumulating the cleaning solution after cleaning the conductive clip 200, for example, as shown in fig. 3, when the cleaning box 110 is used as a cleaning tank, the conductive clip 200 can be directly cleaned in the cleaning solution in the cleaning tank, the metal ion concentration in the cleaning solution in the cleaning tank is detected by the first metal ion concentration detector 131, and when the metal ion concentration is greater than the predetermined concentration, the first control valve 141 is controlled to be opened, so that the cleaning solution with higher metal ion concentration in the cleaning tank flows into the recovery box 120.
For example, as shown in fig. 4, the cleaning tank 110 is a device for accumulating the cleaning liquid of the cleaning-completed jig 200 in the cleaning device, wherein the cleaning device further includes a nozzle 113 and a pump 160, an outlet of the pump 160 is connected to the nozzle 113, an inlet of the pump 160 is connected to the cleaning tank 110, the pump 160 can pump the cleaning liquid in the cleaning tank 110 to the nozzle 113, the nozzle 113 sprays the cleaning liquid to the jig 200, and the cleaning liquid of the cleaning-completed jig 200 flows into the cleaning tank 110.
If the first control valve 141 is manually controlled, when the first metal ion concentration detector 131 detects that the metal ion concentration in the cleaning solution in the cleaning tank 110 is greater than the preset value, an alarm may be used to warn an operator to remind the operator to manually open the first control valve 141 so that the cleaning solution in the cleaning tank 110 flows into the recycling tank 120, otherwise, the first control valve 141 is not operated, so that the cleaning solution in the cleaning tank 110 continues to be used for cleaning the conductive clip 200.
If the first control valve 141 is automatically controlled, a first controller 181 may be adopted, as shown in fig. 5, the first controller 181 is electrically connected to the first metal ion concentration detector 131 and the first control valve 141, respectively, the first controller 181 is configured to control the first control valve 141 to open or close according to detection information of the first metal ion concentration detector 131, specifically, when the first metal ion concentration detector 131 detects that the metal ion concentration in the cleaning solution in the cleaning tank 110 is greater than a preset concentration, the first metal ion concentration detector 131 sends a detection signal to the first controller 181, the first controller 181 controls the first control valve 141 to open according to the received detection signal, so that the cleaning solution in the cleaning tank 110 flows into the recovery tank 120, the recovery tank 120 can reduce the concentration of the metal ions in the entering cleaning solution, otherwise, the first controller 181 controls the first control valve 141 to close, so that the cleaning liquid in the cleaning tank 110 is continuously used to clean the conductive clip 200, and thus, the degree of automation of opening or closing the first control valve 141 is improved.
In one possible implementation of this embodiment, the recovery tank 120 contains a displacing agent capable of displacing metal ions in the cleaning solution in the reaction tank, as shown in fig. 6, to generate a water-insoluble metal compound 103, thereby separating the metal ions in the cleaning solution from the cleaning solution.
For example, the metal compound containing metal ions in the cleaning solution is CuSO4The displacing agent is Na2CO3The metathesis reaction that occurs is:
CuSO4+Na2CO3+H2O＝Cu2(OH)2CO3↓+Na2SO4+CO2×. therefore, it can be seen that Na passes through the substituting agent2CO3So that the metal ion Cu2+Metal compound 103 rendered water-insoluble, i.e. Cu2(OH)2CO3。
The above is merely illustrative of the reaction of the metal ions with the displacing agent to form the water-insoluble metal compound 103, and no limitation on the metal ions and/or displacing agent is to be understood, as would be known to one skilled in the art.
In order to increase the reaction rate of the metal ions in the cleaning solution in the recovery tank 120 and the displacing agent, a stirring device is disposed in the recovery tank 120, and the stirring device is used for stirring the cleaning solution in the recovery tank 120 and the displacing agent to mix.
Optionally, as shown in fig. 7, the stirring device includes a driving machine 121 and a stirring plate 122 connected to the driving end of the driving machine 121, the stirring plate 122 is disposed in the recovery tank 120, and the driving machine 121 provides rotational power to drive the stirring plate 122 to stir in the recovery tank 120, so that the cleaning liquid and the displacing agent in the recovery tank 120 are uniformly stirred, thereby increasing the reaction rate of the metal ions in the cleaning liquid and the displacing agent, and improving the effect of the recovery tank 120 on the treatment of reducing the ion concentration of the cleaning liquid.
The effect of the treatment of reducing the ion concentration of the cleaning liquid by the recovery tank 120 is improved by providing the stirring device in the recovery tank 120, but the concentration of the metal ions in the cleaning liquid after the treatment of the recovery tank 120 is difficult to determine, and whether the cleaning liquid after the treatment of the recovery tank 120 meets the standard of the cleaning conductive clip 200 is determined. In a possible implementation manner of this embodiment, as shown in fig. 8 and 9, a second control valve 142 is disposed between the outlet 123 of the recycling bin and the recycling inlet 111, a second metal ion concentration detector 132 is disposed in the recycling bin 120, the second control valve 142 and the second metal ion concentration detector 132 are further electrically connected to a second controller 182, and the second controller 182 is configured to control the second control valve 142 to open or close according to the metal ion concentration in the cleaning liquid in the recycling bin 120 detected by the second metal ion concentration detector 132, so that whether the cleaning liquid processed in the recycling bin 120 enters the cleaning bin 110 can be controlled by detecting the metal ion concentration in the cleaning liquid in the recycling bin 120, and thus it is ensured that the cleaning liquid flowing from the recycling bin 120 to the cleaning bin 110 meets the standard of cleaning the conductive clip 200 again.
Specifically, a preset concentration is preset in the second controller 182, where the preset concentration is a boundary point of a metal ion concentration in the cleaning liquid capable of cleaning the conductive clip 200, and when the second metal ion concentration detector 132 detects that the metal ion concentration in the cleaning liquid in the recovery box 120 is greater than or equal to the preset concentration, the second controller 182 controls the second control valve 142 to close, and the recovery box 120 continues to perform the ion concentration reduction treatment on the cleaning liquid in the recovery box 120, for example, by increasing the amount of the substitution agent, so as to make the metal ions in the cleaning liquid in the recovery box 120 react as completely as possible, thereby reducing the metal ion concentration in the cleaning liquid in the recovery box 120. When the second metal ion concentration detector 132 detects that the metal ion concentration in the cleaning solution in the recycling bin 120 is less than the preset concentration, the second controller 182 controls the second control valve 142 to open, so that the cleaning solution processed by the recycling bin 120 enters the cleaning bin 110 through the second control valve 142 and the recycling inlet 111 for continuously cleaning the conductive clip 200. Therefore, the concentration of the metal ions in the cleaning liquid in the recycling bin 120 can be detected at any time, and the concentration of the metal ions in the cleaning liquid entering the recycling bin 120 can be ensured, so that the cleaning effect of the conductive clip 200 is improved.
The power for the cleaning liquid flowing from the cleaning tank 110 to the recycling tank 120 includes two types, one type is the power provided according to the pressure difference, specifically, as shown in fig. 2, the cleaning tank 110 is located above the recycling tank 120, and the horizontal height of the waste liquid outlet 112 is higher than the horizontal height of the inlet of the recycling tank 120, so that the pressure difference is formed between the waste liquid outlet 112 and the inlet of the recycling tank 120, when the first control valve 141 is opened, the cleaning liquid in the cleaning tank 110 flows from the waste liquid outlet 112 to the inlet of the recycling tank 120 to enter the recycling tank 120, and no other power is needed, thereby saving energy. The other is the power provided by the water pump 160, specifically, as shown in fig. 10, the inlet of the second water pump 162 is connected to the waste liquid outlet 112 through the first control valve 141, the outlet of the second water pump 162 is connected to the inlet of the recovery tank 120, the inlet of the third water pump 163 is connected to the outlet 123 of the recovery tank, and the outlet of the third water pump 163 is connected to the recovery inlet 111, when the first control valve 141 is opened, the second water pump 162 operates to pump the cleaning liquid in the cleaning tank 110 into the recovery tank 120, and after the recovery tank 120 completes the ion concentration reduction process, the third water pump 163 operates to pump the cleaning liquid in the recovery tank 120 into the cleaning tank 110, without considering the setting positions of the cleaning tank 110 and the recovery tank 120, that is, the setting of the positional relationship between the two is flexible. Therefore, the selection of the power for the cleaning liquid to flow from the cleaning tank 110 to the recovery tank 120 can be performed by those skilled in the art according to actual needs.
When the concentration of the metal ions in the cleaning liquid in the recycling bin 120 is less than the predetermined concentration, the cleaning liquid in the recycling bin 120 needs to be recycled into the cleaning bin 110 for cleaning the conductive clip 200 again, however, since the water-insoluble metal compound 103 is mixed in the cleaning liquid in the recycling bin 120, in order to remove the water-insoluble metal compound 103 from the cleaning liquid, as shown in fig. 11, a filtering device 170 is disposed between the recycling bin 120 and the cleaning bin 110, and the filtering device 170 is used for filtering the water-insoluble metal compound 103, so that the water-insoluble metal compound 103 in the cleaning liquid entering the cleaning bin 110 from the recycling bin 120 is filtered out, and thus, the cleaning liquid containing a lower concentration of the metal ions or containing no metal ions is recycled, and the recycling effect of the cleaning liquid is further improved.
Specifically, the filtering device 170 is a filter screen 171, and the mesh of the filter screen 171 allows the cleaning solution to pass through and can prevent the water-insoluble metal compound 103 from passing through. For example, the particle diameter of the water-insoluble metal compound 103 is 0.5mm, and the diameter of the mesh of the filter screen 171 is set to be less than 0.5mm, so as to ensure that the water-insoluble metal compound 103 is completely filtered, so that the cleaning liquid entering the cleaning tank 110 from the recovery tank 120 does not contain the water-insoluble metal compound 103, and further improve the filtering effect of the cleaning liquid.
Optionally, the filter screen 171 is disposed at the outlet 123 of the recycling bin, so that the water-insoluble metal compounds in the cleaning solution passing through the outlet 123 of the recycling bin are filtered out, the structure is simple, and the filtering effect is good. For example, as shown in fig. 12, when the cleaning liquid in the recovery tank 120 flows out from the outlet 123 of the recovery tank, the filter screen 171 allows the cleaning liquid to pass through, so that the water-insoluble metal compound 103 is left in the recovery tank 120, and the cleaning liquid in the cleaning tank 110 is pumped to the recovery tank 120 by the second suction pump 162 to perform the ion concentration reduction treatment.
In order not to affect the ion concentration reduction treatment of the recycling bin 120 on the cleaning liquid entering constantly, the water-insoluble metal compound 103 generated by the displacement reaction needs to be removed in time, in a possible implementation manner, as shown in fig. 13, the recycling bin 120 is further provided with a slag discharge port 124, a dissolving bin 150 is further connected to the slag discharge port 124, that is, the slag discharge port 124 is further connected to an inlet of the dissolving bin 150, a dissolving agent is contained in the dissolving bin 150, the dissolving agent is used for dissolving the water-insoluble metal compound 103 to generate an electroplating solution, and the generated electroplating solution enters the electroplating solution tank 11 through an outlet of the dissolving bin 150, so that the generated water-insoluble metal compound 103 is recycled, and the waste of resources is reduced.
Specifically, a control valve is provided at the slag discharge port 124, and when the cleaning liquid in the recovery tank 120 is completely discharged to the cleaning tank 110, the control valve is opened to discharge the water-insoluble metal compound 103 in the recovery tank 120 to the dissolution tank 150, and the position where the slag discharge port 124 is provided is not limited herein, for example, the slag discharge port 124 is provided at the bottom of the recovery tank 120.
Continuing to take the water-insoluble metal compound 103 as Cu2(OH)2CO3The process of dissolving the water-insoluble metal compound 103 by the dissolving agent is illustrated by way of example: if the dissolving agent is H2SO4Dissolving agent H2SO4Dissolving Cu2(OH)2CO3The chemical reaction of (A) is as follows:
Cu2(OH)2CO3+2H2SO4＝2Cu SO4+3H2O+CO2×) and Cu SO formed4And H2O is a main component constituting the plating solution, and it can be seen that the water-insoluble metal compound 103 chemically reacts with the dissolving agent to produce the plating solution.

The reservoir 190 is used to accumulate the cleaning liquid after the treatment of the recovery tank 120, and when the cleaning liquid in the cleaning tank 110 is insufficient, the reservoir 190 supplies the cleaning liquid to the cleaning tank 110.
The position of the filter 171 in the reservoir 190 is not limited, and for example, the filter 171 is provided at the inlet of the reservoir 190, or the filter 171 is provided at the top of the inner space of the reservoir 190, and the water-insoluble metal compound 103 in the cleaning liquid introduced into the reservoir 190 can be filtered out.
Illustratively, as shown in fig. 14, a filter screen 171 is provided at the top of the inner space of the reservoir 190, and the filter screen 171 has a predetermined angle with the horizontal direction, that is, the interval between one side of the filter screen 171 and the top of the water storage tank 190 is smaller than the interval between the other side of the filter screen 171 and the top of the water storage tank 190, one side of the filter screen 171 is defined as an inlet side, the other side of the filter screen 171 is defined as an outlet side, a slag discharge port 124 is arranged on the side wall of the water storage tank 190 close to the outlet side, a control valve is arranged at the slag discharge port 124, when the amount of the water-insoluble metal compound 103 on the filter screen 171 is large, the control valve is opened, so that the metal compound 103 which is not dissolved in water is sent out from the slag discharging port 124, and because the slag discharging port 124 is connected with the inlet of the dissolving tank 150, so that the water-insoluble metal compound 103 discharged from the slag discharge port 124 enters the dissolution tank 150 to be dissolved.
In addition, the power for the cleaning liquid to enter the water storage tank 190 from the recovery tank 120 and to enter the cleaning tank 110 from the water storage tank 190 can be provided by the pressure difference or the water pump 160, and the specific process is similar to the above description and will not be described herein.
