[0035] The first liquid level monitor is connected with the first control valve 9 and the second control valve 10; the first liquid level monitor is used to monitor the liquid level of the coupling agent solution in the preparation tank 2, the first control valve 9 is used to discharge a certain volume of undiluted coupling agent from the raw liquid tank 1 into the preparation tank 2, and the second control valve 10 is used to discharge the same volume of the preparation agent from the reflux tank 8 into the preparation tank 2, so as to adjust the delivery amount of the raw liquid tank 1 and the reflux tank 8 into the preparation tank 2, and further realize the adjustment of the concentration of the coupling agent in the preparation tank 2.

[0036] The second liquid level monitor is connected with the third control valve 11 and the concentration monitoring device 5, the concentration monitoring device 5 is used to monitor the concentration of the coupling agent in the solution in the liquid supply tank 3, under the monitoring of the second liquid level monitor, the third control valve 11 is used to discharge the liquid in the liquid supply tank 3 to a set value, and the first delivery pump 4 is used to discharge the corresponding volume of the coupling agent solution from the preparation tank 2 into the liquid supply tank 3 to a certain liquid level, so as to adjust the delivery amount of the preparation tank 2 into the liquid supply tank 3, and further realize the adjustment of the concentration of the coupling agent in the liquid supply tank 3, so that the concentration of the coupling agent entering the coupling treatment section 6 meets the use standard.

[0037] Meanwhile, under the monitoring of the second liquid level monitor, when the liquid level in the liquid supply tank 3 reaches the warning liquid level, the third control valve 11 is used to discharge the liquid in the liquid supply tank 3 to the upper limit liquid level of the liquid supply, so as to avoid that the liquid in the liquid supply tank 3 exceeds the tank volume.

[0038] Specifically, when it is monitored that the liquid level of the preparation tank 2 reaches a set value, the first control valve 9 and the second control valve 10 are opened at the same time, and the coupling agent raw liquid and the preparation agent enter the preparation tank 2 at a set fixed flow rate to prepare the liquid; when it is monitored that the liquid level in the liquid supply tank 3 reaches a set value, the first delivery pump 4 is started to deliver the prepared solution in the preparation tank 2 into the liquid supply tank 3.

[0039] In some embodiments, the preparation tank 2 comprises a tank body 201, a stirring motor 202 is arranged at the top of the tank body 201, an output shaft of the stirring motor 202 is fixedly connected with a stirring rod 203, and the stirring rod 203 extends to the inside of the tank body 201 at the bottom; a stirring paddle 204 is arranged at the bottom of the stirring rod 203, and the stirring motor 202 rotates to drive the stirring paddle 204 to rotate through the stirring rod 203, so as to realize the sufficient mixing of the coupling agent raw liquid and the preparation agent.

[0040] In some embodiments, a control system is further included, the control system is electrically connected with the first control valve 9, the second control valve 10, the first delivery pump 4 and the second delivery pump 7, and the automatic preparation and liquid supply of the liquid supply system can be realized.

[0041] The specific working principle is as follows:

[0042] The first liquid level monitor monitors the liquid level of the coupling agent solution in the preparation tank 2. The first control valve 9 and the second control valve 10 are used to adjust the amount of raw liquid tank 1 and reflux tank 8 supplied to the preparation tank 2 respectively. The coupling agent and the blending agent are added according to the preset ratio to make the concentration of the coupling agent in the preparation tank 2 reach the set value.

[0043] The stirring motor 202 is started, and the stirring rod 203 drives the stirring paddle 204 to rotate in the tank body 201, so as to realize the full mixing of the coupling agent raw liquid and the blending agent.

[0044] After the preparation is completed, the first delivery pump 4 is started to deliver the prepared coupling agent solution to the liquid supply tank 3, and the second delivery pump 7 delivers the solution in the liquid supply tank 3 to the coupling treatment section 6 after passing through the concentration monitoring device 5. During this process, the concentration monitoring device 5 monitors the concentration of the solution passing through. If the concentration meets the requirements, the solution can be directly used in the coupling treatment section 6. If the concentration is unqualified, under the monitoring of the liquid level monitor, the third control valve 11 of the liquid supply tank 3 is opened to discharge the corresponding volume of low-concentration solution to a pre-set liquid level, and then the first delivery pump 4 is used to deliver the high-concentration coupling agent solution prepared in the preparation tank 2 to the liquid supply tank 3 to a certain liquid level, so as to reach the appropriate coupling agent concentration range, so that the concentration of the solution in the liquid supply tank 3 meets the use requirements of the coupling treatment section 6.

[0045] Example 2:

[0046] The difference between this embodiment and example 1 is:

[0047] The outlet of the coupling treatment section 6 is connected with the liquid supply tank 3 and the reflux tank 8, so that the coupling agent solution that is not combined with the surface of the copper foil can be recycled, the utilization rate of the coupling agent is improved, the waste is reduced, and the cost is reduced. The coupling agent solution flowing into the reflux tank 8 can be used as a blending agent, the coupling agent solution flowing into the liquid supply tank 3 can be mixed with the coupling agent mixture in the liquid supply tank 3, the concentration in the liquid supply tank 3 is reduced, and the concentration of the coupling agent solution flowing out of the liquid supply tank 3 meets the use standard of the coupling treatment section 6. This device can ensure that the concentration of the coupling agent solution in the preparation tank 2 is higher than that in the liquid supply tank 3 after the coupling agent solution that is not combined with the surface of the copper foil is recycled, so as to mix with the lower-concentration solution after recycling, so that the concentration of the solution meets the use requirements of the coupling treatment section 6.

[0048] In some embodiments, the reflux tank 8 includes an overflow port arranged at the top of the reflux tank 8. The overflow port is connected with the inlet of the liquid supply tank 3. When the amount of the solution stored in the reflux tank 8 reaches a certain amount and cannot store more solution, the excess solution is introduced into the liquid supply tank 3 through overflow.

[0049] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
