Description

Technical Field

[0001] This utility model relates to the field of electroplating tank technology, and in particular to an electroplating tank with automatically adjustable temperature. Background Technology

[0002] In the electroplating process, the temperature inside the electroplating bath has a crucial impact on the electroplating quality. Temperatures that are too high or too low will both lead to a decline in the quality of the electroplated layer. For example, excessively high temperatures may cause the electroplating solution to decompose, resulting in a rough or burnt coating; while excessively low temperatures will slow down the electroplating process and weaken the adhesion of the coating.

[0003] Currently, most electroplating tanks have a relatively simple temperature control method, which usually involves manually controlling the heating or cooling devices. This not only results in low adjustment accuracy but also fails to automatically adjust according to real-time temperature changes within the electroplating tank, making it difficult to meet the requirements of high-quality electroplating.

[0004] Therefore, it is necessary to provide an electroplating bath with automatically adjustable temperature to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides an electroplating tank with automatically adjustable temperature, solving the problems in the background art.

[0006] To address the aforementioned technical problems, this utility model provides an electroplating tank with automatically adjustable temperature, comprising an electroplating tank body. Inside the electroplating tank body, from bottom to top, are installed a first temperature sensor, a second temperature sensor, and a third temperature sensor. These three temperature sensors are evenly distributed at different heights within the electroplating tank, monitoring temperature changes in various areas of the tank in real time and providing data support for temperature regulation. A heating chamber and a cooling chamber are respectively installed on the outer surface of the electroplating tank body. A first circulation pump is installed on the top surface of the heating chamber, with its input end connected to the electroplating tank body via a pipe, and its output end connected to the electroplating tank body via a first return pipe. A second circulation pump is installed on the top surface of the cooling chamber, with its input end connected to the electroplating tank body via a pipe, and its output end connected to the electroplating tank body via a second return pipe. This connection enables the electroplating solution to circulate between the electroplating tank body and the heating and cooling chambers, allowing for heating or cooling as needed. The heating chamber is equipped with a second electric heating rod for heating the electroplating solution entering the heating chamber; the cooling chamber is filled with coolant to absorb the heat from the electroplating solution.

[0007] Preferably, a filter plate is installed inside the electroplating tank body for filtering the electroplating solution; a drive motor is installed on the bottom surface of the electroplating tank body, and its output end is connected to a stirring assembly consisting of a rotating disk and a stirring rod through the bottom surface of the electroplating tank body. The drive motor drives the stirring assembly to rotate, so that the electroplating solution flows fully and mixes evenly in the tank, promoting uniform distribution of components and rapid temperature diffusion.

[0008] Preferably, both the heating chamber and the cooling chamber have liquid inlets on their top surfaces for easy addition of coolant or replenishment of heating medium; and each has a second drain pipe installed below its surface, with a valve on the second drain pipe for draining liquid from the chamber.

[0009] Preferably, a first electric heating rod is installed on the inner wall of the electroplating tank body, which works in conjunction with a second electric heating rod in the heating box to heat up the electroplating solution when the temperature is too low.

[0010] Preferably, the bottom of the electroplating tank body is equipped with multiple sets of support legs, and these support legs are evenly distributed at the bottom of the electroplating tank body to stably support the electroplating tank body and ensure working stability.

[0011] Preferably, a first drain pipe is installed through the lower surface of the electroplating tank body, and a valve is installed on the first drain pipe for draining the electroplating solution in the electroplating tank body, so as to facilitate the replacement of the electroplating solution or the cleaning of the equipment.

[0012] Preferably, a controller is installed on the outer surface of the electroplating tank body. The temperature sensor transmits the monitored temperature data to the controller. The controller controls the start and stop of components such as the first circulation pump, the second circulation pump, the first electric heating rod, the second electric heating rod, and the drive motor according to the preset temperature threshold, so as to realize the automatic adjustment of the temperature of the electroplating tank and the stirring control of the electroplating solution.

[0013] Compared with related technologies, the electroplating bath with automatically adjustable temperature provided by this utility model has the following beneficial effects:

[0014] Compared with existing technologies, by installing first, second, and third temperature sensors inside the electroplating tank, temperature changes at different heights within the tank can be monitored in real time. Combined with external heating and cooling chambers, and corresponding first and second circulation pumps, the heating or cooling program can be automatically activated based on data from the temperature sensors. This achieves precise temperature regulation within the electroplating tank, preventing problems such as roughness, scorching, and poor adhesion of the electroplated layer caused by excessively high or low temperatures, thus significantly improving electroplating quality.

[0015] Compared to existing technologies, the filter plate installed inside the electroplating tank works in conjunction with the drive motor and stirring components (rotary disc and stirring rod) at the bottom. The drive motor rotates the stirring components to agitate the electroplating solution, ensuring that the solution flows fully and mixes evenly within the tank. This not only helps to evenly distribute the components in the electroplating solution but also allows for rapid temperature diffusion within the tank, preventing uneven local temperatures and further improving the stability and quality of the electroplating process.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Please refer to the following: Figure 1-4 An electroplating tank with automatic temperature adjustment is disclosed, comprising an electroplating tank body 1. The tank body 1 is characterized by having a first temperature sensor 11, a second temperature sensor 12, and a third temperature sensor 13 installed sequentially from bottom to top inside the tank body 1. These temperature sensors are securely installed in pre-set mounting holes on the side wall of the electroplating tank body 1 via threaded connections or slot fixation, and are evenly distributed at different heights within the tank, enabling real-time monitoring of temperature changes in the upper, middle, and lower regions of the electroplating solution. The collected temperature data is transmitted via wires to an external control system, providing accurate data support for subsequent temperature adjustment.

[0026] The outer surface of the electroplating tank body 1 is fitted with a heating box 2 and a cooling box 4 by welding or bolting. A first circulation pump 15 is installed on the top surface of the heating box 2. Its input end is connected to the outlet on the bottom side of the electroplating tank body 1 via a high-temperature, corrosion-resistant rubber pipe, and its output end is connected to the inlet on the top side of the electroplating tank body 1 via a first return pipe 14 passing through the top of the heating box 2. Similarly, a second circulation pump 18 is installed on the top surface of the cooling box 4. Its input end is connected to another outlet on the bottom side of the electroplating tank body 1 via a rubber pipe, and its output end is connected to another inlet on the top side of the electroplating tank body 1 via a second return pipe 17 passing through the top of the cooling box 4. This connection method enables the electroplating solution to circulate between the electroplating tank body 1 and the heating box 2 and cooling box 4. When heating is required, the first circulation pump 15 starts, pumping the low-temperature electroplating solution into the heating chamber 2. After being heated by the internal second electric heating rod 16, it returns to the electroplating tank through the first return pipe 14. When cooling is required, the second circulation pump 18 starts, pumping the high-temperature electroplating solution into the cooling chamber 4. After being cooled by the internal coolant absorbing heat, it flows back to the electroplating tank through the second return pipe 17, thus heating or cooling the electroplating solution as needed. The second electric heating rod 16 is fixedly installed inside the heating chamber 2 by a bracket. It uses the principle of resistance heating to heat the electroplating solution entering the heating chamber 2. The cooling chamber 4 is filled with coolant. The coolant absorbs the heat of the electroplating solution through heat transfer, thereby cooling the electroplating solution.

[0027] Example 2

[0028] Please refer to the following: Figure 1-4 Inside the electroplating tank body 1, a filter plate 10 is installed by welding or bolting. The filter plate 10 is located above the stirring assembly 9 and is used to filter impurities in the electroplating solution, ensuring the cleanliness of the electroplating solution. A drive motor 6 is bolted to the bottom surface of the electroplating tank body 1. The output end of the drive motor 6 passes through a pre-set through hole on the bottom surface of the electroplating tank body 1 and is connected to the stirring assembly 9, which consists of a rotating disk and a stirring rod, via a coupling. During installation, the drive motor 6 is first fixed to the bottom of the electroplating tank body 1, and then the stirring assembly 9 is connected to the output end of the drive motor 6 via the coupling, ensuring that the two rotate coaxially. After the drive motor 6 is started, it drives the stirring assembly 9 to rotate. The stirring rod agitates the electroplating solution, allowing the electroplating solution to flow fully and mix evenly in the tank. This not only helps to evenly distribute the chemical components in the electroplating solution but also promotes rapid temperature diffusion in the tank, avoiding uneven local temperature distribution and further improving the stability and quality of electroplating.

[0029] Example 3

[0030] Please refer to the following: Figure 1-4Both the heating chamber 2 and the cooling chamber 4 have liquid inlets 20 on their top surfaces, each with a sealing cap installed via a threaded connection for easy access to add coolant or heating medium. A second drain pipe 19 is welded to the bottom of each surface, and a valve is installed on the second drain pipe 19 via a threaded connection to drain liquid from the chamber, facilitating equipment maintenance and cleaning.

[0031] Example 4

[0032] Please refer to the following: Figure 1-4 The inner wall of the electroplating tank body 1 is fitted with a first electric heating rod 8 by welding or bolting. The first electric heating rod 8 works in conjunction with a second electric heating rod 16 inside the heating chamber 2. When the temperature of the electroplating solution is too low, the first electric heating rod 8 directly heats the electroplating solution in the electroplating tank, while the second electric heating rod 16 heats the electroplating solution circulating into the heating chamber 2. The two work together to accelerate the heating rate of the electroplating solution and ensure that the electroplating solution quickly reaches the appropriate working temperature.

[0033] Example 5

[0034] Please refer to the following: Figure 1-4 The electroplating tank body 1 has multiple sets of support legs 7 fixed to its bottom end by bolts, and these support legs 7 are evenly distributed at the bottom end of the electroplating tank body 1. When installing the support legs 7, it is necessary to ensure that the bottom of the support legs 7 is on the same horizontal plane. By adjusting the adjusting bolts at the bottom of the support legs 7, the horizontality of the electroplating tank body 1 is ensured, the electroplating tank body 1 is stably supported, and it is prevented from tilting or shaking during operation, thus ensuring operational stability.

[0035] Example 6

[0036] Please refer to the following: Figure 1-4 A first drain pipe 5 is welded through the lower surface of the electroplating tank body 1. A valve is installed on the first drain pipe 5 and is threadedly connected to the first drain pipe 5. When it is necessary to replace the electroplating solution or clean the electroplating tank, the valve can be opened to drain the electroplating solution from the electroplating tank body 1, making the operation convenient and quick.

[0037] Example 7

[0038] Please refer to the following: Figure 1-4A controller 3 is installed on the outer surface of the electroplating tank body 1 by bolts. A temperature sensor transmits the monitored temperature data to the controller 3 via wires. The controller 3 has a preset temperature threshold and controls the start and stop of components such as the first circulation pump 15, the second circulation pump 18, the first electric heating rod 8, the second electric heating rod 16, and the drive motor 6 through internal circuitry and programs. For example, when the temperature is higher than the upper threshold, the controller 3 controls the second circulation pump 18 to start and simultaneously shuts down the heating components; when the temperature is lower than the lower threshold, the controller 3 controls the first circulation pump 15, the first electric heating rod 8, and the second electric heating rod 16 to start, thereby achieving automatic temperature adjustment of the electroplating tank and stirring control of the electroplating solution, ultimately realizing the technical effect of automatic temperature adjustment and improved electroplating quality claimed in the patent.

[0039] It should be noted that the control circuit of controller 3 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0040] The working principle of the electroplating tank with automatically adjustable temperature provided by this utility model is as follows:

[0041] When the electroplating tank starts working, the first temperature sensor 11, the second temperature sensor 12 and the third temperature sensor 13 inside the electroplating tank body 1 begin to monitor the temperature of the electroplating solution at different heights in real time and transmit the data to the controller 3 installed on the outer surface of the electroplating tank body 1.

[0042] When the temperature is too high: If the temperature sensor detects that the electroplating solution temperature exceeds the preset upper limit threshold, the controller 3 immediately issues a command to start the second circulation pump 18 at the top of the cooling tank 4. The second circulation pump 18 draws the high-temperature electroplating solution from the electroplating tank into the cooling tank 4 through a pipeline. The coolant inside the cooling tank 4 absorbs the heat of the electroplating solution and cools it down. The cooled electroplating solution is then returned to the electroplating tank body 1 through the second return pipe 17, and this cycle continues until the electroplating solution temperature drops to a suitable range. During this process, the stirring component 9 operates continuously under the drive of the drive motor 6, accelerating the flow of the electroplating solution and allowing the cooled electroplating solution to quickly mix with the original electroplating solution in the tank, uniformly reducing the temperature inside the tank.

[0043] When the temperature is too low: When the temperature sensor detects that the electroplating solution temperature is lower than the preset lower threshold, the controller 3 will start the first circulation pump 15 at the top of the heating tank 2. The first circulation pump 15 transports the lower-temperature electroplating solution from the electroplating tank to the heating tank 2, where the second electric heating rod 16 inside the heating tank 2 heats the incoming electroplating solution. The heated electroplating solution flows back to the electroplating tank body 1 through the first return pipe 14, continuously circulating and heating the electroplating solution. At the same time, the first electric heating rod 8 installed on the inner wall of the electroplating tank body 1 also works in conjunction to heat the electroplating solution. The stirring assembly 9 continuously stirs the electroplating solution, promoting rapid and uniform heat diffusion, so that the temperature of the electroplating solution rises rapidly to a suitable range.

[0044] Throughout the electroplating process, the stirring component 9 remains operational, accelerating heat transfer and mixing during temperature regulation, and ensuring thorough mixing of the chemical substances in the electroplating solution. This guarantees the uniformity of the electroplating solution composition and provides a stable environment for high-quality electroplating. Furthermore, the first drain pipe 5, which runs through the lower surface of the electroplating tank body 1, and the second drain pipe 19, which runs through the heating chamber 2 and cooling chamber 4, allow for convenient and quick drainage of the liquid when the electroplating solution needs to be replaced or the interior of the tank needs to be cleaned, simply by opening the valves.

[0045] It should be noted that all components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
