Description

Technical Field

[0002] In the field of electroplating, the performance of electroplating equipment plays a crucial role in ensuring electroplating quality. With the rapid development of the electronics industry, applications such as battery cell electroplating place extremely high demands on electroplating uniformity.

However, the bottom plate is prone to deformation after the plating solution is injected. This seemingly minor phenomenon can trigger a series of serious problems. For example, deformation of the tank bottom plate alters the spacing between the anode plates in the anode assembly placed inside the tank, and consequently changes the spacing between the anode plates and the battery cells held in the basket for plating, ultimately severely affecting the uniformity of electroplating. Insufficient electroplating uniformity leads to unstable performance of plated parts such as battery cells, increasing the defect rate, reducing production efficiency, and increasing production costs, becoming one of the key issues restricting the further development of the electroplating industry.

[0063] Embodiment 1

[0064] The tank body of the conventional electroplating equipment is generally made of plastic material. Such a plastic tank body has the advantages of relatively low cost and good corrosion resistance to some extent. However, when the tank body is filled with chemical solution, the bottom plate is prone to deformation. This seemingly minor phenomenon can cause a series of serious problems. For example, the deformation of the tank body bottom plate can change the spacing between the anode sheets in the anode assembly placed in the tank body, and the spacing between the anode sheets and the battery sheets clamped by the baskets will also change, which will eventually seriously affect the uniformity of electroplating. Insufficient electroplating uniformity can cause unstable performance of plated parts such as battery sheets, increase the rate of defective products, reduce production efficiency, and increase production cost, which has become one of the key problems restricting the further development of the electroplating industry.

The bending piece includes a horizontal part and a vertical part, the horizontal part of the bending piece is used for fixing with anode positioning block 2, and the vertical part of the bending piece extends out of the anode plate 42 and bends upward.

[0069] In this embodiment, the bottom of anode carrying frame 1 includes a plurality of parallel metal rods, and anode positioning block 2 is fixed on part of the metal rods. As shown, Figure 2 Each metal rod is fixed with three anode positioning blocks 2. Of course, the number of anode positioning blocks 2 on the metal rod can also be changed according to the needs.

First, a set screw is inserted into the set screw hole 51, and then the four corners of the anode carrying frame 1 are adjusted horizontally by the set screw, and finally the anode carrying frame 1 is fixed by a fixing screw.

[0072] In this embodiment, as shown in Figure 6 , the tank of the electroplating equipment includes a main tank and a sub-tank. The anode carrying frame 1 is fixed in the main tank, and the sub-tank is arranged on the lower side of the main tank and communicates with the main tank. The sub-tank is used to transport electroplating liquid to the main tank and recover the electroplating liquid escaping from the main tank.

[0073] Further, as shown in Figure 6 , the main tank includes an outer tank and an inner tank arranged inside the outer tank. The height of the inner tank is lower than that of the outer tank, and the anode carrying frame is fixed in the inner tank.
