The copper foil 7 is pre-plated in the pre-plating tank 11 through the anode plate on the side wall, so that the seed film can be thickened and reinforced in a short time after entering the pre-plating tank 11, reducing the damage to the seed film coating and the pollution of the liquid by the falling of particles, improving the electroplating efficiency and the uniformity of metal ion implantation and deposition, ensuring the uniformity and consistency of the coating, and finally entering the electroplating tank 12 for complete electroplating through the upper electrode plate 3 and the lower electrode plate 4, which can improve the density of the coating, reduce the occurrence of missed plating pinholes and bumps, improve quality and reduce overall cost.

[0018] In some embodiments, connecting rods 211 are provided on both sides of the first guide roller 21, and the connecting rods 211 are rotatably connected to the pre-plating tank 11. A sliding rod 231 is provided on both sides of the second guide roller 23, and the two sliding rods 231 are slidably connected to the tank body 1. A cam 232 is provided on the inner wall of the tank body 1 below the two sliding rods 231. A transmission member 212 is provided between the connecting rod 211 and the cam 232, and the connecting rod 211 and the cam 232 rotate in opposite directions. The transmission member 212 is an eight-shaped transmission wheel. Before using the device, the operator flips the connecting rod 211 and fixes it with the tank body 1. The clamping is a prior art and will not be described in detail here, so that the first guide roller 21 moves from the tank body 1 to the tank body 1, then the rotation of the connecting rod 211 drives the transmission member 212 to perform transmission work, and then the transmission member 212 drives the cam 232 to rotate, and the cam 232 lifts the sliding rod 231 to allow the second guide roller 23 to move from the inside of the tank body 1 to the outside of the tank body 1, and finally the first guide roller 21, the first submerged roller 22, the second guide roller 23 and the second submerged roller 24 guide the copper foil 7, and the electroplating operation can be started, which is very convenient and quick. After use, the first guide roller 21 can be turned over to the inside of the tank body 1, thereby driving the cam 232 to reset, and finally the second guide roller 23 falls to the initial position under the influence of gravity, that is, the reset is completed, and the operator can cover the surface of the tank body 1 with a cover plate to prevent dust from entering the tank body 1, reduce internal pollution, and ensure the electroplating effect.

[0019] In some embodiments, a liquid inlet pipe 5 is provided on one side of the bottom of the pre-plating tank 11, and a liquid extraction pipe 6 is provided on the other side. Both the liquid inlet pipe 5 and the liquid extraction pipe 6 are connected to a pump, which can fully perform high-precision filtration and purification on the liquid in the pre-plating tank 11 to prevent the liquid in the pre-plating tank 11 from being contaminated and further contaminating the electroplating tank 12.

[0020] In some embodiments, two second guide rollers 23 are provided, and a slide bar 231 is welded on both sides of the two second guide rollers 23, a cam 232 is provided under each slide bar 231, and a gear 233 is fixedly connected to each cam 232, and the gears 233 on the same side are meshed with each other. When the operator needs to perform electroplating, taking one side as an example, when the operator folds the first guide roller 21 out of the trough body 1, the first guide roller 21 immediately drives the connecting rod 211 to rotate, and the connecting rod 211 drives the transmission member 212 to transmit, and then the transmission member 212 drives the cam 232 to rotate, and the cam 232 drives the corresponding gear 233 to rotate. Since the two gears 233 on the same side are meshed with each other and the rotation direction In the opposite direction, that is, the rotation directions of the two cams 232 are also opposite, so that the two cams 232 each push the sliding rod 231 corresponding to its own position to move upward, so that the two second guide rollers 23 rise from the tank body 1, and then the copper foil 7 is guided by the first guide roller 21, the first submerged roller 22, the second guide roller 23 and the second submerged roller 24, and the electroplating operation can be carried out. The guidance of the two second guide rollers 23 can increase the span distance of the copper foil 7 from the pre-plating tank 11 to the electroplating tank 12, and avoid the contact between the copper foil 7 and the tank body 1, which affects the electroplating effect. If the electroplating work is completed and the device needs to be reset, it is only necessary to fold the first guide roller 21 down and enter the tank body 1, and drive the above-mentioned components to rotate and reset, so as to realize the device reset, and the operation is simple and quick.
