Technical Field
[0001] The utility model relates to the technical field of electrolytic copper foil, in particular to a device for avoiding back-splash of electrolyte in an electrolysis machine. Background Art
[0002] In recent years, in the 5G era, the markets of automotive electronics, consumer electronics, etc. have been booming, with higher and higher requirements for technology, and thus stricter requirements for printed circuits. Printed circuit boards are usually manufactured by forming a plating layer on a copper foil laminate and then forming a circuit pattern on the formed plating layer.
[0003] For the copper foil used in the above copper foil laminate, electrolytic copper foil is generally used. The electrolytic copper foil process requires an anode tank, and the cathode roller rolls in the anode tank to drive the electrolytic copper foil to contact with the electrolyte. The appearance and physical properties requirements of electrolytic copper foil are becoming more and more stringent. Poor appearance not only directly affects the quality grade, but also has a greater impact on downstream products. Therefore, there must be no appearance abnormalities such as water droplet imprints on the smooth surface of the copper foil. However, when the electrolyte in the existing anode tank returns, due to the relatively large return liquid drop, the falling electrolyte will splash and the bubbles will burst, and it will splash back onto the electrolytic copper foil, causing water droplet imprints on the smooth surface of the copper foil, resulting in the product not meeting the requirements and being scrapped. Therefore, it is urgent to solve this problem. Summary of the Utility Model
[0004] The utility model provides a device for avoiding back-splash of electrolyte in an electrolysis machine, which can solve the problem that the electrolyte return liquid in the existing electrolysis machine splashes back onto the electrolytic copper foil, resulting in water droplet imprints on the smooth surface of the copper foil.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A device for avoiding back-splash of electrolyte in an electrolysis machine, including a diversion plate, installed at the liquid inlet end of the cathode roller in the anode tank. The diversion plate is installed at a position corresponding to the liquid return port of the anode tank. The diversion plate includes a plate body. One side of the plate body is provided with a plurality of downward-extending extension parts and a plurality of outward diversion parts. By installing a diversion plate corresponding to the liquid return port at the liquid inlet end of the cathode roller, the electrolyte return liquid can be diverted to the liquid return port. When it falls through the extension parts, the return liquid drop can be reduced, and the water droplet back-splash and bubble bursting can be reduced. At the same time, the diversion parts can divert a part of the electrolyte to a position away from the cathode roller.
[0006] Preferably, the plate body is a long strip-shaped plate body, and the extension parts are uniformly arranged along the length direction of the plate body, which can be matched with the width direction of the anode tank.
[0007] Preferably, the extension parts and the diversion parts are arranged at intervals alternately, which is beneficial to the diversion and guiding of the electrolyte.
[0008] Preferably, a chamfered portion is provided on the other side edge of the plate body.
[0009] Preferably, the extension portion is an inclined panel that slopes downward, which can provide good drainage for the electrolyte, helping to reduce the backflow drop and minimize water droplet back-splash and bubble explosion.
[0010] Preferably, the acute angle α between the extension portion and the plate body is 45°.
[0011] Preferably, the guiding portion is in the shape of a long strip plate, with a simple structure.
[0012] Preferably, the guiding plate is made of PVC material, which has good heat resistance, acid and alkali resistance, providing a stable environment during the use of the guiding plate.
[0013] Preferably, the guiding plate is of an integrally formed structure, with high structural strength and convenient installation.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] The structure is simple. By installing a guiding plate corresponding to the liquid return port at the liquid inlet end of the cathode roller, the liquid return of the electrolyte can be guided to the liquid return port. The liquid falling through the extension portion can reduce the liquid return drop and minimize the water droplet back-splash and bubble explosion. At the same time, the guiding portion can guide a part of the electrolyte to a position far from the cathode roller, preventing appearance defects such as water droplet back-splash on the surface of the cathode roller.

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0022] The present utility model aims to solve the problem that the liquid return of the electrolyte in the existing electrolysis machine splashes back onto the electrolytic copper foil, resulting in water droplet imprints on the smooth surface of the copper foil. As Figures 1-3As shown, the following technical solution is provided: a device for preventing the back-splash of electrolyte in an electrolysis machine, including a flow guide plate 2, which is installed at the liquid inlet end of the cathode roller in the anode tank 1. The flow guide plate 2 is installed at a position corresponding to the liquid return port of the anode tank 1. The flow guide plate 2 includes a plate body 21. On one side of the plate body 21, there are several downward-extending extension parts 23 and several outward flow guide parts 22. By installing the flow guide plate 2 corresponding to the liquid return port at the liquid inlet end of the cathode roller, the liquid return of the electrolyte can be diverted to the liquid return port. When it falls through the extension parts 23, the liquid return drop can be reduced, and the back-splash of water droplets and the explosion of bubbles can be reduced. At the same time, the flow guide parts 22 can divert a part of the electrolyte to a position far from the cathode roller.
[0023] Specifically, a reserved position can be set at the liquid inlet end of the cathode roller in the anode tank 1. The reserved position corresponds to the liquid return port. An installation groove is provided at the reserved position. The flow guide plate 2 can be snap-fitted and installed in the installation groove. The plate body 21 can be fixed to the side wall of the liquid return port. The extension parts 23 mainly play a role in diverting the electrolyte in the anode tank 1. The electrolyte falls from the lower end of the extension parts 23 into the liquid return port, which can reduce the liquid return drop. The flow guide parts 22 can divert a part of the electrolyte to a position far from the cathode roller and then let it fall. In this way, even if there is back-splash of water droplets and explosion of bubbles, it will not splash onto the electrolytic copper foil on the cathode roller.
[0024] The edge of the flow guide plate 2 has no burrs, cracks and irregular edges, and will not interfere with the diversion and flow guiding.
[0025] In this embodiment, as Figures 1-2 shown, the plate body 21 is a long strip-shaped plate body. The extension parts 23 are uniformly arranged along the length direction of the plate body 21 and can be matched with the width direction of the anode tank 1. Among them, the extension parts 23 and the flow guide parts 22 are arranged at intervals alternately, which is beneficial to the diversion and flow guiding of the electrolyte.
[0026] In this embodiment, as Figures 2-3 shown, a chamfered part 24 is provided on the other side edge of the plate body 21, which is beneficial to the smooth flow of the electrolyte when it flows through the plate body 21 and prevents back-splash.
[0027] In this embodiment, as Figure 2 shown, the extension part 23 is a downward-inclined inclined plate, which can divert the electrolyte well, is beneficial to reducing the liquid return drop and reducing the back-splash of water droplets and the explosion of bubbles. The acute angle a between the extension part 23 and the plate body 21 is 45°. The inclined plate is 460 mm long, 66.5 mm wide and 10 mm wide.
[0028] At the same time, the flow guide part 22 is a long strip plate-shaped structure, with a simple structure, 275 mm long, 80 mm wide and 20 mm wide, and the structure is compact.
[0029] In this embodiment, the flow guide plate 2 is made of PVC material, which has good heat resistance, acid and alkali resistance, providing a stable environment for the use of the flow guide plate. At the same time, the flow guide plate 2 is an integrally formed structure with high structural strength and convenient installation.
