Description

Technical Field

[0001] This utility model belongs to the field of electroplating tank technology, specifically relating to a deep blind hole electroplating tank structure with precise temperature control function. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. The electroplating tank is the most basic supporting facility in electroplating equipment.

[0003] Chinese Patent Publication No. CN108103561A discloses an electroplating tank, including a main tank body, an overflow tank, a variable temperature tank, and a variable temperature pump. The outer wall of the main tank body is provided with an overflow port, which is connected to the overflow tank. The variable temperature tank includes an inlet, an outlet, and a variable temperature pipe. The overflow tank and the main tank body are both connected to the inlet of the variable temperature pump. The outlet of the variable temperature pump is connected to the inlet. The variable temperature pipe is located inside the variable temperature tank, and its outlet is connected to the main tank body. The inlet and outlet of the variable temperature pipe are respectively connected to a variable temperature fluid pipe.

[0004] The above technical solutions have solved the corresponding technical problems. However, the electroplating tank structure in the above technology has many shortcomings in terms of temperature control. On the one hand, traditional electroplating tanks usually use simple heating devices to heat the electroplating solution, but lack effective cooling methods, which makes the operation cumbersome and inefficient when it is necessary to reduce the temperature of the electroplating solution. On the other hand, due to the special structure of the deep blind hole, the temperature distribution of the electroplating solution in the tank is often uneven. The temperature is higher in the area near the heating device and lower in the area far from the heating device. This temperature difference will seriously affect the electroplating effect, resulting in unstable electroplating layer quality, and even defects such as coating peeling and bubbles. Utility Model Content

[0005] The purpose of this invention is to provide a deep blind hole electroplating tank structure with precise temperature control function, so as to solve the technical defects of existing electroplating tank structures that lead to unstable electroplating layer quality due to insufficient temperature control, and even plating layer peeling and bubble defects.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0037] The electroplating tank body 1 is equipped with a temperature sensor 102 for real-time monitoring of the temperature of the electroplating solution inside the electroplating tank body 1, and a temperature controller 1021 electrically connected to the temperature sensor 102 is also installed on the side of the electroplating tank body 1.

[0038] The above technical solution, by setting up a plate heater 101 and a plate heat exchanger 1011, achieves the dual functions of heating and cooling the electroplating solution inside the electroplating tank body 1. With the cooperation of the temperature sensor 102 and the temperature controller 1021, the temperature of the electroplating solution can be monitored in real time, and the heating or cooling power can be automatically adjusted according to the set value, thereby achieving precise temperature control of the electroplating solution and ensuring that the electroplating process is carried out within the optimal temperature range. At the same time, by setting up a mixing component 2, the electroplating solution inside the electroplating tank body 1 can be effectively stirred. Under the stirring action of the mixing component 2, temperature dead zones and gradients are effectively eliminated, making the temperature distribution of the electroplating solution more uniform, thereby improving the quality and consistency of the electroplated layer.

[0039] To facilitate fixing the mounting bracket 201 to the side of the electroplating tank body 1, two symmetrically arranged fixing bolts 2011 are installed on the mounting bracket 201, and the mounting bracket 201 is fixedly installed to the side of the electroplating tank body 1 by the fixing bolts 2011.

[0040] To facilitate the rotational drive of the agitation assembly 205, the rotational drive assembly 202 includes a rotary motor 2021 fixedly connected to the fixed frame 201, a rotary seat 2022 fixedly connected to the output shaft of the rotary motor 2021, and a vertical electric cylinder 203 fixedly connected to the top of the rotary seat 2022.

[0041] In order to limit the rotation of the rotating seat 2022 and thus increase the stability of the rotation of the rotating seat 2022, limit balls 2023 are installed on both sides of the bottom of the rotating seat 2022, and the bottom of the rotating seat 2022 is rolledly connected to the top of the fixed frame 201 through the limit balls 2023.

[0042] To facilitate the lateral driving of the agitation assembly 205, the lateral driving assembly 204 includes an electric cylinder frame 2041 fixedly connected to the output end of the vertical electric cylinder 203, and a lateral electric cylinder 2042 is mounted on the electric cylinder frame 2041.

[0043] To facilitate the stirring and mixing of the electroplating solution inside the electroplating tank body 1, the stirring assembly 205 includes a mounting base 2051 fixedly connected to the output end of the horizontal electric cylinder 2042. A stirring motor 2052 is mounted on the mounting base 2051, a stirring shaft 2053 is mounted on the output shaft of the stirring motor 2052, and stirring blades 2054 are mounted on the bottom of the stirring shaft 2053.

[0046] In summary, this embodiment of the utility model achieves the dual functions of heating and cooling the electroplating solution inside the electroplating tank body 1 by setting up a plate heater 101 and a plate heat exchanger 1011. With the cooperation of the temperature sensor 102 and the temperature controller 1021, the temperature of the electroplating solution can be monitored in real time by the temperature sensor 102, and the heating or cooling power can be automatically adjusted by the temperature controller 1021 according to the set value, thereby achieving precise temperature control of the electroplating solution and ensuring that the electroplating process is carried out within the optimal temperature range.

[0047] Meanwhile, by setting up the mixing component 2, when it is necessary to stir and mix the electroplating solution inside the electroplating tank body 1, it is only necessary to drive the stirring component 205 to rotate above the electroplating tank body 1 by the rotary motor 2021, and then drive the stirring blade 2054 to immerse in the electroplating solution by the vertical electric cylinder 203. Then, the stirring motor 2052 drives the stirring blade 2054 to stir the electroplating solution. At the same time, the horizontal drive component 204 drives the mounting base 2051 to move horizontally. Therefore, the electroplating solution inside the electroplating tank body 1 can be uniformly mixed, thereby effectively eliminating temperature dead zones and gradients, making the temperature distribution of the electroplating solution more uniform, and thus improving the quality and consistency of the electroplating layer.

[0048] After agitation is completed, the vertical electric cylinder 203 drives the agitator blade 2054 to detach from the electroplating tank body 1, and then the horizontal electric cylinder 2042 retracts the mounting base 2051. At the same time, the rotary motor 2021 rotates the agitator 205 to the side away from the electroplating tank body 1, thereby avoiding the agitator 205 from affecting the electroplating of objects inside the electroplating tank body 1.

[0049] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
