Description

Technical Field

[0001] The embodiments of the present utility model relate to, but are not limited to, the field of electroplating equipment, and in particular to an immersion plating tank structure with a stable liquid level. Background Art

[0002] At present, the immersion plating tank is the main area for electroplating operations in electroplating equipment. It contains the electroplating solution for immersion plating of workpieces that require surface treatment. When the existing electroplating solution circulates, since the electroplating solution is directly added to the immersion plating tank, the liquid level of the electroplating solution is prone to excessive fluctuations, causing the air brought into the liquid during the electroplating process to be adsorbed on the surface of the electroplated product, thereby causing quality problems such as uneven coating thickness, bubbles or spots, affecting the quality stability of the electroplated products. Utility Model Content

[0003] (1) Technical issues to be solved

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides an immersion plating tank structure with stable liquid level, which solves the technical problem that when the existing electroplating solution circulates, the electroplating solution is directly added to the immersion plating tank, which easily causes the electroplating solution liquid level to fluctuate too much, resulting in the air brought into the liquid during the electroplating process being adsorbed on the surface of the electroplated product, thereby causing quality problems such as uneven coating thickness, bubbles or spots, and affecting the quality stability of the electroplated product.

[0005] (2) Technical solution

[0006] The purpose of the utility model is to provide an immersion plating tank structure with a stable liquid level, which includes a load-bearing plate and a main tank body arranged at the upper end of the load-bearing plate, a main tank cavity is arranged in the main tank body, a high-position bracket is arranged at the lower end of the load-bearing plate, a secondary tank body is arranged on the side end face of the main tank body, a secondary tank cavity is arranged in the secondary tank body, two or more liquid flow holes connecting the inner cavities of the two are arranged between the secondary tank body and the main tank body, the part of the liquid flow hole facing the main tank cavity is trumpet-shaped, a baffle plate is arranged on the upper end of the main tank cavity, two or more defoaming holes are arranged on the baffle plate, and a water inlet pipe interface is also provided on the back of the secondary tank body.

[0007] Preferably, an anode bracket is further provided at the upper end of the main tank body.

[0008] Preferably, overflow ports are provided on the groove walls at both ends of the main groove body.

[0009] Preferably, an auxiliary tank cover is further provided at the upper end of the auxiliary tank body.

[0010] Preferably, the liquid flow hole faces the bottom of the main tank cavity.

[0011] (3) Beneficial effects

[0012] During the circulation of the electroplating solution, it first flows into the sub-tank body and, through liquid collision, offsets part of the gas mixed in when the electroplating solution is extracted, and then enters the main tank cavity of the main tank body through the trumpet-shaped liquid flow hole. The trumpet-shaped liquid flow hole can reduce the flow rate of the fluid entering the main tank cavity, and the liquid pressure with reduced flow rate is reduced, further reducing the generation of bubbles. The baffle plate adopts a hollow design with multiple defoaming holes, which reduces the direct contact between the liquid surface and the air and also reduces the disturbance of the liquid surface, thereby changing the surface tension of the liquid surface, thereby reducing the formation of foam, avoiding excessive fluctuations in the liquid level of the electroplating solution, resulting in uneven liquid concentration and temperature during the electroplating process, and then causing quality problems such as uneven coating thickness, bubbles or spots, thereby improving the quality stability of electroplated products.

[0021] In a preferred embodiment, overflow ports 21 are provided on the two end walls of the main tank body 2 so that the added electroplating solution can flow out of the main tank cavity 20 through the overflow ports 21 opened at both ends, so as to facilitate the collection of the electroplating solution.

[0022] In a preferred embodiment, a sub-tank cover 41 is further provided at the upper end of the sub-tank body 4 .
