Referring to FIG. 1, a surging electrode fabrication system according to an embodiment of the present invention includes a reaction system 1 and a circulation system 2 for placing an electrode product and performing development, etching, and stripping processes, including an outer tank 11 and The inner tank 12 and the surge device 13 in the outer tank 11 and the circulation system 2 include an inlet pipe 21, a liquid outlet pipe 22 and a power unit 23, and the inlet pipe 21 passes through the outer tank 11 and is connected to the bottom of the inner tank 12. The liquid outlet pipe 22 is connected to the bottom of the outer tank 11 and on a different side from the inlet pipe 21. The power unit 23 includes a power pump connected between the inlet pipe 21 and the outlet pipe 22 for supplying power to the circulation system 2 to allow the liquid to flow from the inlet pipe 21 into the inner tank 12 and to the electrode in the inner tank 12. After the product is processed, the liquid level reaches a certain height and overflows from the inner tank 12, and flows into the outer tank 11 and flows out from the liquid outlet tube 22 to realize the liquid circulation. The ring and the repeated use; the surge device 13 is disposed in the inner tank 12, and includes a conveying device 131 for conveying the electrode from the side of the liquid outlet pipe 22 toward the liquid inlet pipe 21 side after the liquid in the inner tank 12 is not over the electrode. Here, the conveying device 131 is a plurality of conveying rollers arranged horizontally, and both sides of the electrode product placed on the conveying roller can be infiltrated by the liquid in the inner tank 12, and various processes are completed under the surge of the liquid.

A set of air knives 10 are respectively installed between the outer groove 11 and the side wall of the inner groove 12, and each set of air knives 10 is disposed on opposite sides of the electrode product, one set of the air knife 10 (close to the side of the liquid outlet pipe 22) After the air knife is blown dry on both sides of the electrode product, the electrode product is sent into the inner tank 12 by the conveying device 131 to be immersed in the liquid and subjected to surge treatment to complete development, etching and stripping, and then through the outer tank 11 A set of air knives 10 (the air knife 10 on the side close to the inlet pipe 21) is dried and sent out. At the same time, since the inner tank 12 is close to the conveying inlet and the outlet of the electrode product, liquid overflows. In order to prevent the liquid from overflowing to the outer tank 11 along the conveying device 131, the air knife 10 on both sides of the inner tank 12 can also form two during the working process. The barrier prevents the overflowing liquid from being trapped in the two barriers, preventing the liquid from overflowing along the handling device 131 to the outside of the outer tank 11.

Specifically, the surge device 13 includes a conveying device 131, a conveying pipe 132, and a branch pipe 133.

On one side, a plurality of branch pipes 133 are intermittently connected to a plurality of portions of the conveying pipe 132 and extend toward the liquid inlet pipe 21, and the top end of the conveying pipe 132 is higher than the conveying device 131, thereby ensuring that the liquid flowing out from the uppermost branch pipe 133 can be From the top to the bottom, the liquid flowing out of the branch pipe 133 below the conveying device 131 can surge from the bottom to the top, so that the surface of the electrode is sufficiently and gently stressed. In other embodiments, the top of the delivery tube 132 can also be perforated with liquid flowing from its top end.

A plurality of through holes (not shown) may be opened above and below the pipe wall of each branch pipe 133, and liquid may flow out from all directions of the pipe wall, and at the same time, at least one branch of the power pipe is disposed in each branch pipe 133. 133a, the power tube 133a is preferably a plurality of, spacedly connected to the pipe wall of each branch pipe 133, perpendicular to the corresponding branch pipe 133 and parallel to the bottom of the inner groove 12 (ie, horizontally disposed), and each power pipe 133a may also be A through hole for the liquid to flow out is opened, so that the outflow portion of the liquid is more, which improves the surge effect of the liquid.

The power pump of the power unit 23 is a variable frequency power pump, and its operating frequency can be adjusted within a certain range, such as 35-75 Hz.
