Description

Technical Field

[0001] The utility model relates to the technical field of eliminating small white dots in the production process of electrolytic copper foil, and specifically relates to a control device for small white dots in the production process of electrolytic copper foil. Background Technique

[0002] Effective control of small white dots in the production process of electrolytic copper foil is crucial. At present, most electrolytic copper foil enterprises have small white dots in the production and manufacturing of copper foil, which have a particularly huge impact on shipping, and there are not a few returns due to customer complaints, causing unnecessary losses to the company. In addition to the defects in the flow rate of the machine itself, the control of the polishing process is also crucial. The main purpose of making this device is to control the electrolyte force to a slow flow state, and stably control the bubbles generated after the electrolyte is electrified under the condition of laminar flow for a long time. After solving the bubbles, the small white dots of the liquid can be effectively controlled, the quality is greatly improved, and the risk of customer complaints and returns due to small white dots is also reduced. Small white dots continuously appear during the production process of the raw foil machine. Analyzing the reasons: since the electrolyte flow rate is too large (52 cubic meters) and is adjusted to (50 cubic meters), the effect is not obvious after adjustment. Small white dots can be seen with the naked eye during online production. Then the flow rate is reduced to (47 cubic meters) again, but the effect is not good after adjustment, and small white dots still exist in the slitting feedback. Various adjustments of the machine itself can no longer meet the needs of most customers.

[0003] Therefore, in order to correct the above defects, we propose a control device for small white dots in the production process of electrolytic copper foil. Content of the Utility Model

[0004] The technical problem solved by the utility model is to propose a control device for small white dots in the production process of electrolytic copper foil.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A control device for small white dots in the production process of electrolytic copper foil, including a baffle plate with a laminar flow surface. The bottom of the laminar flow surface has a support plate, and one side of the laminar flow surface has an inclined impact surface, and the other side of the laminar flow surface has a downward sliding surface. The bottoms of the inclined impact surface and the downward sliding surface are both far from the center line of the laminar flow surface.

[0006] Further, the laminar flow surface, the inclined impact surface and the downward sliding surface are integrally formed.

[0007] Further, the support plate is inclined relative to the laminar flow surface.

[0008] Further, the materials of the laminar flow surface, the inclined impact surface, the downward sliding surface and the support plate are all PVC.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: During the electrolysis of the electrolyte, a large number of bubbles are generated. When too many bubbles burst during the flowing process, small white dots are generated on the surface of the cathode roller. This device is placed at the liquid return port of the polishing end to increase the liquid level height, so that the liquid flow surges upward when passing through, weakening the bubbles, thereby achieving good control of the bubbles and reducing the small white dots.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] The present utility model provides a technical solution:

[0017] Please refer to Figures 1-3 , a device for controlling small white dots in the production process of electrolytic copper foil, including a baffle plate 1. The baffle plate 1 is placed at the liquid return port of the polishing end of the electrolytic cell. The baffle plate 1 includes a flat flow surface 1-1. The bottom of the flat flow surface 1-1 has a support plate 1-4, and one side of the flat flow surface 1-1 has an inclined impact surface 1-2, and the other side of the flat flow surface 1-1 has a downward sliding surface 1-3. The bottom of the inclined impact surface 1-2 and the downward sliding surface 1-3 are both far from the center line of the flat flow surface 1-1. The inclined impact surface 1-2 makes the liquid flow surge upward when passing through, weakening the bubbles, thereby achieving good control of the bubbles and reducing the small white dots. The downward sliding surface 1-3 makes the liquid flow down slowly to avoid generating bubbles.

[0018] Among them, the flat flow surface 1-1, the inclined impact surface 1-2 and the downward sliding surface 1-3 are integrally formed, that is, the three are set through a single whole plate, and the support plate 1-4 is set separately with a single whole plate, which is not available due to the phenomenon of being washed away caused by excessive flow rate.

[0019] Moreover, the support plate 1-4 is inclined relative to the advection surface 1-1 to meet the installation requirements.

[0020] Under the condition of the same flow rate (47 cubic meters), the original baffle plate 1 was visible to the naked eye when it was online. After the improved baffle plate 1 was tested, it curled downwards. The CCD detection after slitting did not feedback any small white dots, and the quality personnel detected that the quality had been improved after curling downwards.

[0021] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
