Description

Technical Field

[0001] This utility model relates to the field of lithium battery copper foil production technology, and in particular to a lithium battery copper foil surface electroplating device. Background Technology

[0002] The main function of the lithium battery copper foil surface electroplating equipment is to perform electroplating treatment on the surface of lithium battery copper foil to enhance the performance of the copper foil, such as conductivity, corrosion resistance, and bonding strength with the resin substrate. Most of the existing electroplating equipment used in electronic copper foil production is static electroplating. As electroplating proceeds, the concentration of plating metal cations around the copper foil decreases. At the same time, the movement speed of plating metal cations in static electroplating is slow, which leads to reduced electroplating efficiency and poor electroplating quality, resulting in poor corrosion resistance, oxidation resistance, and other properties of the lithium battery copper foil. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to provide a lithium battery copper foil surface electroplating device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a lithium-ion battery copper foil surface electroplating device, including an electroplating tank and a lithium-ion battery copper foil. A first roller and a second roller are disposed on the top of the electroplating tank. An anode assembly and a cathode assembly are disposed inside the electroplating tank. Two first rotating shafts, a second rotating shaft, and three third rotating shafts are rotatably connected inside the electroplating tank. The two first rotating shafts, the second rotating shaft, and the three third rotating shafts are perpendicularly distributed inside the electroplating tank. Spiral fan blades are fixedly installed on the surfaces of the two first rotating shafts and the three third rotating shafts are fixedly installed on the surfaces of the three third rotating shafts. The three third rotating shafts are arranged in a triangular shape inside the electroplating tank. Third rollers are rotatably connected inside the electroplating tank. Two mutually perpendicular surfaces of the electroplating tank are respectively provided with actuators for driving the first rotating shafts. The technical effect achieved by the first and second drive devices of the second and third rotating shafts is as follows: the first, second, and third rollers guide the lithium-ion copper foil into the electroplating tank for electroplating. Simultaneously, the first motor, through the cooperation of the first and second sprockets, vertical and horizontal chains, causes the two first and second rotating shafts to rotate, which in turn causes the spiral fan blades to rotate rapidly, moving the metal cations laterally. At the same time, the second motor, in cooperation with the third sprocket and the transmission chain, drives the third rotating shaft and the vertical stirring plate to rotate, moving the metal cations vertically. This allows for the rapid replenishment of metal cations around the lithium-ion copper foil, resulting in higher electroplating efficiency and better electroplating effect, improving the corrosion resistance and oxidation resistance of the lithium-ion copper foil.

[0006] Preferably, in any of the above solutions, the third roller is located at the center of the three third rotating shafts, and the lithium-ion copper foil is disposed on the surface of the first, second, and third rollers. The height of the second roller is greater than the height of the first roller. The technical effect achieved by adopting the above solution is that, by having the third roller located at the center of the three third rotating shafts, the metal cations above and below the lithium-ion copper foil can be moved quickly to replenish it, resulting in higher electroplating efficiency and better electroplating effect, and improving the corrosion resistance, oxidation resistance, and other properties of the lithium-ion copper foil.

[0007] Preferably, in any of the above schemes, the vertical stirring plate is an arc-shaped plate, and there are several vertical stirring plates. The several vertical stirring plates are circumferentially distributed on the surface of the third rotating shaft. The technical effect achieved by the above scheme is that the contact area with the electroplating solution can be wider by several arc-shaped vertical stirring plates, thereby enabling more metal cations to be moved.

[0008] Preferably, in any of the above schemes, the two first rotating shafts and the second rotating shaft are arranged at the four points of the rectangle, and one end of the first rotating shaft, the second rotating shaft and the third rotating shaft all penetrate the electroplating bath. The technical effect achieved by the above scheme is that the two first rotating shafts can quickly drive the metal cations to move laterally, and the three third rotating shafts can quickly drive the metal cations to move vertically.

[0009] Preferably, in any of the above solutions, the first driving device includes a first motor, a first sprocket, and a second sprocket. The first sprocket and the second sprocket are fixedly mounted on the surface of the first rotating shaft, and the second sprocket is fixedly mounted on the surface of the second rotating shaft. One end of the motor output shaft is connected to a first rotating shaft. A vertical chain is provided on the surface of the first sprocket, and a horizontal chain is provided on the surface of the second sprocket. The first motor is fixedly mounted on one side of the electroplating tank. The technical effect achieved by the above solution is that the motor drives a first rotating shaft to rotate, and then the two first rotating shafts rotate synchronously through the cooperation of the second chain and the vertical chain. At the same time, through the cooperation between the second sprockets on the two first rotating shafts and the horizontal chain, the two first rotating shafts and the second rotating shaft rotate simultaneously, which can save energy and reduce costs.

[0010] Preferably, in any of the above solutions, the second drive device includes a second motor, which is fixedly installed on one side of the electroplating tank. One end of the output shaft of the second motor is connected to a third rotating shaft. A third sprocket is fixedly installed on the surface of each of the three third rotating shafts, and a transmission chain is provided on the surface of each third sprocket. The technical effect achieved by the above solution is that the second motor drives a third rotating shaft to rotate, and then the three rotating shafts rotate synchronously through the cooperation between the third sprockets on the surface of the three third rotating shafts and the transmission chain, which can save energy and reduce costs.

[0011] Preferably, in any of the above solutions, the anode assembly is disposed on the inner wall of the electroplating tank near the first driving device. The technical effect achieved by the above solution is that by placing the anode assembly on the inner wall of the electroplating tank near the first driving device, the spiral fan blades can quickly drive the metal cations to move around the third roller.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

Vertical stirring plates 10 are fixedly installed on the surfaces of the three third rotating shafts 8. The three third rotating shafts 8 are arranged in a triangular shape inside the electroplating tank 1. A third roller 11 is rotatably connected inside the electroplating tank 1. A first driving device 12 and a third driving device 13 are respectively disposed on two mutually perpendicular surfaces of the electroplating tank 1 to drive the first rotating shafts 6, the second rotating shaft 7, and the third rotating shafts 8. The second drive device 13 guides the lithium-ion battery copper foil 14 into the electroplating tank 1 via the first roller 2, the second roller 3, and the third roller 11 for electroplating. Simultaneously, the first motor 1201 operates by cooperating with the first sprocket 1202, the second sprocket 1203, the vertical chain 1204, and the horizontal chain 1205 to rotate the two first shafts 6 and the second shaft 7. This causes the spiral fan blades 9 to rotate rapidly, driving the metal cations to move laterally. At the same time, the second motor 1301, in cooperation with the third sprocket 1302 and the transmission chain 1303, drives the third shaft 8 and the vertical stirring plate 10 to rotate, driving the metal cations to move vertically. This allows for the rapid replenishment of metal cations around the lithium-ion battery copper foil, resulting in higher electroplating efficiency and better electroplating effect, improving the corrosion resistance and oxidation resistance of the lithium-ion battery copper foil.

By positioning the third roller 11 at the center of the three third rotating shafts 8, the metal cations above and below the lithium-ion copper foil 14 can be moved quickly to replenish it, making the electroplating efficiency higher and the electroplating effect better, thereby improving the corrosion resistance, oxidation resistance and other properties of the lithium-ion copper foil.

Then, the two first rotating shafts 6 rotate synchronously through the cooperation of the second chain 1203 and the vertical chain 1204. At the same time, through the cooperation between the second sprocket 1203 and the horizontal chain 1205 on the two first rotating shafts 6 and the second rotating shaft 7, the two first rotating shafts 6 and the second rotating shaft 7 can rotate simultaneously, which can save energy and reduce costs.

[0027] As an optional technical solution of this utility model, the second drive device 13 includes a second motor 1301, which is fixedly installed on one side of the electroplating tank 1.

A transmission chain 1303 is provided on the surface of the third sprocket 1302. The second motor 1301 drives one of the third rotating shafts 8 to rotate. Then, through the cooperation between the third sprockets 1302 and the transmission chain 1303 on the surfaces of the three third rotating shafts 8, the three rotating shafts 8 rotate synchronously, which can save energy and reduce costs.

[0029] A lithium-ion battery copper foil surface electroplating device operates on the following principle: A first roller 2, a second roller 3, and a third roller 11 guide the lithium-ion battery copper foil 14 into the electroplating tank 1 for electroplating. Simultaneously, a first motor 1201, through the cooperation of a first sprocket 1202, a second sprocket 1203, a vertical chain 1204, and a horizontal chain 1205, causes two first rotating shafts 6 and a second rotating shaft 7 to rotate. This causes the spiral fan blades 9 to rotate rapidly, moving metal cations laterally. Simultaneously, a second motor 1301, in cooperation with the third sprocket 1302 and the transmission chain 1303, drives a third rotating shaft 8 and a vertical stirring plate 10 to rotate, moving metal cations vertically. This rapidly replenishes the metal cations around the lithium-ion battery copper foil, resulting in higher electroplating efficiency and better electroplating effects, improving the corrosion resistance and oxidation resistance of the lithium-ion battery copper foil.
