Description

Technical Field

[0001] The present application relates to the technical field of electrolytic copper foils, and particularly to an auxiliary cathode mold for electrolytic copper foils and an electrolytic copper foil system. Background Art

[0002] In recent years, with the rapid development of the electronic information industry, it has promoted the rapid rise of upstream copper foil enterprises. Among them, electrolytic copper foil is a process of using electrochemical reaction to deposit copper ions on the cathode roller through electrolysis to form a thin film. In the technical field of copper foil production, the cathode roller is an essential component. The production of copper foil is to first dissolve copper in the electrolyte, and then use the cathode roller to continuously attract copper ions in the electrolyte. After obtaining electrons in the electrolyte, the copper ions become copper atoms and deposit on the surface of the continuously rotating cathode roller. As the cathode roller rotates slowly, metallic copper continuously precipitates and adheres to the surface of the cathode roller. The metallic copper is stripped from the surface of the rotating cathode roller, and then the electrolytic copper foil is wound by a winding roller to obtain the electrolytic copper foil.

[0003] Among them, the electrolytic copper foil system consists of a cathode roller, an anode, and an electrolyte. In the production process, when too much electrolyte overflows from the side of the cathode roller, electrodeposition will occur, causing damage to the cathode roller. In order to extend the service life of the cathode roller, during the production process, an auxiliary cathode is usually arranged beside the cathode roller, so that the overflowing electrolyte is transferred to the auxiliary cathode through the electrodeposition reaction, thereby protecting the cathode roller.

[0004] However, few people pay attention to the auxiliary cathode. At present, the shaping of the auxiliary cathode is bent manually, and the contact area with the electrolyte is small. It needs to be replaced monthly, which greatly wastes manpower and material resources and reduces production efficiency. In addition, the shape of the auxiliary cathode is simple and not completely unified, with different sizes and lengths, and the shape selectivity is relatively limited. Summary of the Utility Model

The auxiliary cathode mold for electrolytic copper foils adopts an automated design, which is more convenient to operate. The auxiliary cathode prepared by the auxiliary cathode mold for electrolytic copper foils provided by the present application can solve the problems of different sizes and lengths of the auxiliary cathode.

[0063] As described in the background art, the auxiliary cathode has received little attention. At present, the shaping of the auxiliary cathode is carried out by manual bending, and the contact area with the electrolyte is small. It needs to be replaced monthly, which greatly wastes manpower and material resources and reduces production efficiency. In addition, the shape of the auxiliary cathode is simple and not completely unified, with different sizes and uneven lengths, and the shape selectivity is relatively limited.

[0064] In view of the above technical problems, the embodiments of the present application provide an electrolytic copper foil auxiliary cathode mold and an electrolytic copper foil system.

Among them, the second mold reciprocates along a first direction, and the first mold and the third mold reciprocate along a second direction. The second mold is located between the first mold and the third mold, and at least one of the first mold and the third mold has a plurality of first bending portions, and the second mold has second bending portions matching the first bending portions. An auxiliary cathode is prepared by the mutual movement between the first mold, the second mold, and the third mold, and the first direction is perpendicular to the second direction. The electrolytic copper foil device includes a cathode roller, an anode, an electrolytic cell, and an auxiliary cathode. Among them, the auxiliary cathode is prepared by the above-mentioned electrolytic copper foil auxiliary cathode mold, and the auxiliary cathode has third bending portions matching the first bending portions and the second bending portions of the electrolytic copper foil auxiliary cathode mold. The cathode roller and the anode are respectively arranged at both ends of the electrolytic cell, and the auxiliary cathode is located on one side of the cathode roller. In this way, the present application provides an electrolytic copper foil auxiliary cathode mold, which is more convenient to operate with an automated design. The auxiliary cathode prepared by the electrolytic copper foil auxiliary cathode mold provided by the present application can solve the problems of different sizes and uneven lengths of the auxiliary cathodes. The irregular design effectively increases the contact area between the auxiliary cathode and the electrolyte, extends the replacement time of the auxiliary cathode, and saves labor and time costs.

[0065] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0066] The embodiments of the present application provide an electrolytic copper foil auxiliary cathode mold and an electrolytic copper foil system. The electrolytic copper foil auxiliary cathode mold is more convenient to operate with an automated design. The auxiliary cathode prepared by the electrolytic copper foil auxiliary cathode mold provided by the present application can solve the problems of different sizes and uneven lengths of the auxiliary cathodes. The irregular design effectively increases the contact area between the auxiliary cathode and the electrolyte, extends the replacement time of the auxiliary cathode, and saves labor and time costs. The following will introduce the specific structures of the electrolytic copper foil auxiliary cathode mold and the electrolytic copper foil system provided by the embodiments of the present application with reference to the accompanying drawings.

[0067] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, in the first aspect of the embodiment of the present application, an electrolytic copper foil auxiliary cathode mold 100 is provided. Among them, in the embodiment of the present application, the electrolytic copper foil auxiliary cathode mold 100 may include a first mold 200, a second mold 300, and a third mold 400. Among them, as Figure 3 shown, the second mold 300 can reciprocate in the first direction, while the first mold 200 and the third mold 400 can reciprocate in the second direction. It should be noted that the first direction can be the Figure 1 x direction in Figure 1 , and the second direction can be the Figure 1 y direction in

[0068] , and the first direction can be perpendicular to the second direction. In a possible implementation manner, as Figure 1 and Figure 4 shown, the second mold 300 can be located between the first mold 200 and the third mold 400, and at least one of the first mold 200 and the third mold 400 has a first bending portion 210. It can be understood that the first mold 200 may have a first bending portion 210, or the third mold 400 may have a first bending portion 210. Accordingly, the second mold 300 has a second bending portion 310 that matches the first bending portion 210. Among them, in a possible implementation manner, the number of the first bending portions 210 and the second bending portions 310 may be several, and the number of the first bending portions 210 is the same as the number of the second bending portions 310. The present application does not limit the number of the first bending portions 210 and the second bending portions 310 here. It can be understood that the first mold 200, the second mold 300, and the third mold 400 can be used to prepare the auxiliary cathode 740. Through the mutual cooperation between the first mold 200, the second mold 300, and the third mold 400, each prepared auxiliary cathode 740 has exactly the same size and shape.

[0069] Based on the above embodiments, in a possible implementation, during the process of preparing the auxiliary cathode 740 of the rod, the first mold 200, the second mold 300, and the third mold 400 move relative to each other, so that the first mold 200, the second mold 300, and the third mold 400 extrude the rod. At this time, the second mold 300 is located inside the housing 110. After the rod is prepared into the auxiliary cathode 740, the first mold 200, the second mold 300, and the third mold 400 continue to move relative to each other to reset. At this time, the second mold 300 can be located inside the housing 110, or partially protrude out of the housing 110, or completely protrude out of the housing 110.

[0070] Continue to refer to Figure 1 and Figure 4 , based on the above embodiments, the electrolytic copper foil auxiliary cathode mold 100 may further include: a slide rail structure 500. The first mold 200 and the third mold 400 are slidably disposed on the slide rail structure 500. In a possible implementation, the slide rail structure 500 may be located on one side of the first mold 200 and the third mold 400. Exemplarily, the slide rail structure 500 is located at the bottom of the housing 110, and the first mold 200 and the third mold 400 may be slidably disposed on the slide rail structure 500. The first mold 200 and the third mold 400 may move along the second direction on the slide rail structure 500, and the first mold 200 and the third mold 400 may move relative to each other, so that the first mold 200 abuts against the third mold 400. Correspondingly, the first mold 200 and the third mold 400 may also move in opposite directions, so that the first mold 200 and the third mold 400 are separated from each other. By the first mold 200 and the third mold 400 sliding back and forth in cooperation on the slide rail structure 500, the shape of the auxiliary cathode 740 is prepared.

[0071] Continue to refer to Figure 1, on the basis of the above embodiments, the electrolytic copper foil auxiliary cathode mold 100 may further include: a suspension rail structure 600. Among them, the suspension rail structure 600 is located on one side of the second mold 300. Exemplarily, the suspension rail structure 600 is located at the top of the housing 110, and the suspension rail structure 600 is connected to the second mold 300. It can be understood that the suspension rail structure 600 can be used to move the second mold 300 in the first direction. In one possible implementation, the second mold 300 can be slidably arranged on the suspension rail structure 600 in the first direction. Or, in another possible implementation, the suspension rail structure 600 can drive the second mold 300 to move in the first direction, that is, the suspension rail structure 600 can drive the second mold 300 to move in the first direction, so that the second mold 300 enters between the first mold 200 and the third mold 400, thereby realizing the preparation of the auxiliary cathode 740. After the preparation of the auxiliary cathode 740 is completed, the first mold 200 and the third mold 400 are opened in the second direction through the slide rail structure 500, and the suspension rail structure 600 drives the second mold 300 to move in the first direction, so that the second mold 300 moves away from between the first mold 200 and the third mold 400.

[0072] Continue to refer to Figure 1 , on the basis of the above embodiments, one end of the first mold 200 or the third mold 400 facing away from the slide rail structure 500 may have a buckle 112, and the buckle 112 corresponds to the inlet end 111. In this way, one end of the rod can enter the interior of the housing 110 along the inlet end 111 and be fixed by the buckle 112. In one possible implementation, the inlet end 111 may be opened on the side of the housing 110 close to the third mold 400, and one end of the rod can be located on the top of the third mold 400 after passing through the inlet end 111. Correspondingly, the buckle 112 may be located on the top of the first mold 200, so that the buckle 112 corresponds to the inlet end 111. Of course, in another possible implementation, the inlet end 111 may be opened on the side of the housing 110 close to the first mold 200, and one end of the rod can be located on the top of the first mold 200 after passing through the inlet end 111. Correspondingly, the buckle 112 may be located on the top of the third mold 400, so that the buckle 112 corresponds to the inlet end 111.

[0073] Continue to refer to Figure 1, on the basis of the above embodiments, a cutting device 120 may be provided on one side of the housing 110 having an inlet end 111. Among them, the cutting device 120 may further include a cutting member 121 and a guiding member 122. The cutting member 121 may be in a knife-like structure, and the guiding member 122 may be a slide rail. The cutting member 121 is slidably disposed on the guiding member 122. It can be understood that the cutting member 121 moves along a first direction on the guiding member 122, and the cutting member 121 is used to cut the rod at the inlet end 111. In a possible implementation manner, when the rod passes through the inlet end 111 and enters the interior of the housing 110, after the auxiliary cathode 740 is prepared by the mutual cooperation among the first mold 200, the second mold 300, and the third mold 400, the cutting device 120 cuts the rod. Of course, in another possible implementation manner, the length of the auxiliary cathode 740 may be estimated, the rod is cut by the cutting device 120, and then the rod is processed by the mutual cooperation among the first mold 200, the second mold 300, and the third mold 400.

[0074] On the basis of the above embodiments, among them, in a possible implementation manner, the rod passes through the inlet end 111 and enters the interior of the housing 110, and one end of the rod located inside the housing 110 is fixedly connected to the buckle 112. It can be understood that the other end of the rod can be continuously fed into the interior of the housing 110 through the inlet end 111 as the first mold 200, the second mold 300, and the third mold 400 move relative to each other.

[0075] Of course, in another possible implementation manner, the rod may be wrapped on the outer surface of the second mold 300 and may move along the first direction with the second mold 300, and cooperate with the first mold 200 and the third mold 400 to be extruded when the first mold 200 and the third mold 400 move in the second direction, so as to prepare the auxiliary cathode 740.

[0076] Continue to refer to Figure 4, based on the above embodiments, in a possible implementation, the first mold 200 may have a first forming surface 220, and the third mold 400 may have a second forming surface 410. A forming cavity 420 may be formed between the first forming surface 220 and the second forming surface 410. The forming cavity 420 is used for the placement of the second mold 300 and the preparation of the auxiliary cathode 740. Correspondingly, the second mold 300 has a third forming surface 320 that matches the inner surface of the forming cavity 420. It can be understood that the first forming surface 220 may be on the side of the first mold 200 facing the second mold 300, and the second forming surface 410 may be on the side of the third mold 400 facing the second mold 300. During the relative movement of the first mold 200 and the third mold 400, a forming cavity 420 may be formed between the first forming surface 220 and the second forming surface 410. The size of the forming cavity 420 may be greater than or equal to the size of the second mold 300, so that the second mold 300 can be located in the forming cavity 420, and the second mold 300 can reciprocate in the forming cavity 420 along the first direction. The third forming surface 320 on the second mold 300 may cooperate with the first forming surface 220 and the second forming surface 410, that is, the third forming surface 320 may cooperate with the inner surface of the forming cavity 420 to prepare the shape of the auxiliary cathode 740.

In a possible implementation, the first forming surface 220 may be provided with a first bending portion 210, or the second forming surface 410 may be provided with a first bending portion 210. The second bending portion 310 provided on the third forming surface 320 cooperates with the first bending portion 210, so that the third forming surface 320 cooperates with the first forming surface 220 or the second forming surface 410.

[0078] Refer to Figure 5 , Figure 6 , Figure 7 And Figure 8 , the second aspect of the embodiments of the present application provides an electrolytic copper foil system 700, which may include a cathode roller 710, an anode 720, an electrolytic cell 730, and an auxiliary cathode 740. Among them, the auxiliary cathode 740 may be prepared by the above-mentioned electrolytic copper foil auxiliary cathode mold 100. In a possible implementation, both the cathode roller 710 and the anode 720 are located in the electrolytic cell 730, and the cathode roller 710 and the anode 720 may be respectively arranged at both ends of the electrolytic cell 730, and the auxiliary cathode 740 may be located on one side of the cathode roller 710.

[0079] Based on the above embodiments, as Figure 5 and Figure 6 shown, the electrolytic cell 730 may be provided with a liquid inlet 731 and a liquid outlet 732. Among them, the liquid inlet 731 and the liquid outlet 732 can supply electrolyte 733 to flow in and out respectively. That is, the electrolyte 733 can enter the electrolytic cell 730 through the liquid inlet 731, and the electrolyte 733 can also flow out of the electrolytic cell 730 through the liquid outlet 732. In one implementation, the cathode roller 710 and the anode 720 are both located in the electrolyte 733. The production process of electrolytic copper foil is completed.

[0080] Based on the above embodiments, among them, in one implementation, as Figure 7 shown, the auxiliary cathode 740 has a third bending portion 741. Among them, the third bending portion 741 matches the first bending portion 210 and the second bending portion 310 of the electrolytic copper foil auxiliary cathode mold 100. In one possible implementation, the number of the third bending portions 741 can be several, and the number of the third bending portions 741 is the same as the number of the first bending portion 210 or the second bending portion 310. The present application does not limit the number of the third bending portions 741 here.

[0081] Continue to refer to Figure 5 and Figure 7 , based on the above embodiments, the third bending portion 741 of the auxiliary cathode 740 is located in the electrolyte 733. It can be understood that the third bending portion 741 of the auxiliary cathode 740 can increase the contact area with the electrolyte 733, extend the replacement time of the auxiliary cathode 740, thereby improving the service life of the cathode roller 710 and saving a large amount of manpower and material resources.

[0082] Continue to refer to Figure 5 , Figure 7 and Figure 8 , based on the above embodiments, the electrolytic copper foil system 700 may further include: a lifting box 750. Among them, the lifting box 750 can be located in the electrolytic cell 730, and the lifting box 750 can be located on one side of the cathode roller 710. In one possible implementation, the auxiliary cathode 740 can be hung on the lifting box 750. It can be understood that the lifting box 750 can be used to support the auxiliary cathode 740, so that the auxiliary cathode 740 can be located on one side of the cathode roller 710. In one possible implementation, at least part of the auxiliary cathode 740 is located in the electrolyte 733, and the third bending portion 741 of the auxiliary cathode 740 is located in the electrolyte 733. The present application embodiments do not limit the hanging position of the auxiliary cathode 740.

[0083] Based on the above embodiments, the material of the auxiliary cathode 740 can be copper. In a possible implementation, the auxiliary cathode 740 can be prepared from a copper rod with a diameter of 6 mm - 20 mm, and the embodiments of the present application are not limited thereto.

[0084] Based on the above embodiments, it can be understood that the auxiliary cathode 740 prepared by the electrolytic copper foil auxiliary cathode mold 100 provided by the present application can have a specific shape. Exemplarily, the auxiliary cathode 740 can be in a serpentine, U-shaped, V-shaped or other structures, and the irregular design can effectively increase the contact area between the auxiliary cathode 740 and the electrolyte 733.

[0085] In the embodiments of the present application, the auxiliary cathode 740 is located on the electrolytic copper foil auxiliary cathode mold 100. By adjusting the positions of the first mold 200 and the third mold 400 on the slide rail structure 500 in the second direction, and adjusting the position of the second mold 300 on the hanging rail structure 600 in the first direction, the auxiliary cathode 740 is located in the molding cavity 420 for molding. Through the mutual cooperation between the first mold 200, the second mold 300 and the third mold 400, the auxiliary cathode 740 is extruded and formed.

[0086] In the embodiments of the present application, in a possible implementation, when the rod penetrates into the interior of the housing 110 through the inlet end 111, the positions of the first mold 200 and the third mold 400 on the slide rail structure 500 are adjusted in the second direction, and then the position of the second mold 300 on the hanging rail structure 600 is adjusted in the first direction, so that the rod can be located between the first mold 200, the second mold 300 and the third mold 400, and through the mutual cooperation between the first mold 200, the second mold 300 and the third mold 400, the auxiliary cathode 740 is prepared. Of course, in some other embodiments, the rod is coated on the outer surface of the second mold 300 and the two ends of the rod are respectively fixed to the second mold 300. When the second mold 300 moves in the first direction, the rod can move in the first direction along with the second mold 300, and cooperate with the first mold 200 and the third mold 400 to be extruded when the first mold 200 and the third mold 400 move in the second direction, so as to prepare the auxiliary cathode 740.

[0087] In the embodiments of the present application, the electrolytic copper foil auxiliary cathode mold 100 is designed automatically, which is more convenient for operation. The auxiliary cathode 740 prepared by the electrolytic copper foil auxiliary cathode mold 100 provided by the present application can solve the problems of different sizes and uneven lengths of the auxiliary cathode 740. The irregular design effectively increases the contact area between the auxiliary cathode 740 and the electrolyte 733, prolongs the replacement time of the auxiliary cathode 740, and saves labor and time costs.
