Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment technology, and in particular relates to a temperature control device for continuous gold and platinum plating. Background Technology

[0002] In metal surface treatment processes, gold, platinum, and other precious metal platings are widely used in electronics, aerospace, jewelry, and high-end industrial products due to their excellent conductivity, oxidation resistance, and aesthetic appeal. Especially in continuous production lines, such as continuous gold (or platinum) plating processes, the requirements for plating thickness, uniformity, adhesion, and appearance quality are extremely stringent, and these performance indicators are closely related to temperature control during the electroplating process.

[0003] Traditional electroplating heating systems typically employ a single heating element or an external heating bath. Due to uneven heat source distribution and low heat transfer efficiency, this often results in inconsistent temperature fields around the plating solution or workpiece, affecting the uniformity and density of the plating layer and leading to problems such as localized excessive thickness, peeling, and flaking. Most existing equipment lacks multi-point dynamic monitoring and adjustment, making it prone to temperature lag or overshoot, failing to meet the constant temperature environment requirements of high-precision electroplating processes. Some equipment lacks a reasonable airflow structure; improper fan arrangement or the absence of airflow guides results in poor air circulation, creating eddies or dead zones, impacting overall heating efficiency and response speed.

[0004] To address these issues, we have provided a temperature control device for continuous gold and platinum plating. Utility Model Content

[0029] Example

[0030] Please see Figure 1-5This utility model is a temperature control device for continuous gold and platinum plating, including a heating chamber 100. The heating chamber 100 includes an upper shell 101, a lower shell 102 disposed opposite to the lower part of the upper shell 101, an air inlet plate 104 disposed between the upper shell 101 and the lower shell 102, a sealing plate 103 covering the upper opening of the upper shell 101, a heat insulation plate 105 installed at the front of the heating chamber 100, a heating tube 106 located inside the heating chamber 100, and guide plates 107 equidistantly arranged at the lower part of the lower shell 102. The upper shell 101 and the lower shell 102 constitute the outer shell structure of the entire device, forming a semi-enclosed space, which facilitates heat concentration and prevents external interference. The sealing plate 103 covers the top opening of the upper shell 101 to enhance the overall airtightness and prevent heat loss and dust entry. The heat insulation plate 105 plays a role in heat insulation and protection, and also serves as an installation platform for the controller 200.

[0031] A controller 200 is fixed on the outside of the heat insulation plate 105. The internal control circuit module 201 of the controller 200 is connected to the terminal of the heating tube 106. The control circuit module 201 is connected to a temperature sensor 202 via internal wires. The temperature sensor 202 is located on the side of the air guide plate 107. Multiple temperature sensors 202 are provided to monitor the air outlet temperature in real time and feed it back to the control circuit module 201.

[0032] Specifically, a fan module 203 is fixed in the middle of the inner side of the sealing plate 103. The fan module 203 is also connected to the control circuit module 201 via wires. The fan module 203 is located directly above the guide plate 107, and the fan module 203 and the air inlet slots opened on the air inlet plate 104 form a heating channel. The fan module 203 is driven by the controller 200 and the air volume can be adjusted. It is used in conjunction with the heating channel formed by the air inlet plate 104 to guide external air into the heating chamber 100.

[0033] The heating tube 106 is arranged along the inner side of the air inlet plate 104, and heat-conducting fins are spirally arranged at equal intervals around the heating tube 106 to increase the heat exchange area, accelerate heat diffusion, and improve thermal efficiency.

[0034] Furthermore, the controller 200 has a display screen and control buttons embedded in its front, and both the display screen and control buttons are connected to the control circuit module 201 through internal wires, providing a convenient human-machine interface.

[0035] The air guide plate 107 is inclined and its two ends are movably connected to the inner wall of the lower opening of the lower housing 102, so as to evenly distribute the airflow direction and improve the heat transfer efficiency. A filter screen is attached to the inner side of the air inlet plate 104. The filter screen is made of high temperature resistant material to filter air impurities and protect the internal equipment from dirt.

[0036] The specific implementation steps of this embodiment are as follows: The temperature control device for continuous gold and platinum plating is applied to the dynamic temperature control in continuous gold and platinum plating processing operations. When using the temperature control device for continuous gold and platinum plating of this utility model for electroplating operations, firstly, according to the process requirements, the target temperature value is set through the control buttons and display screen on the controller 200, and the equipment is started. After receiving the instruction, the control circuit module 201 in the controller 200 starts working, the heating tube 106 is energized and heated, and at the same time the fan module 203 starts, guiding the external air through the filter screen and into the heating chamber 100 through the air inlet plate 104. As the heat-conducting plates arranged in an equidistant spiral around the heating tube 106 accelerate the heat transfer, the air is rapidly heated and pushed by the fan module 203, and guided out through the inclined guide plate 107, forming a stable and uniform heating airflow. During this process, multiple temperature sensors 202 located on the side of the guide plate 107 monitor the temperature changes at the air outlet in real time and feed the data back to the control circuit module 201. The control circuit module 201 automatically adjusts the heating power or fan speed based on this feedback information to ensure that the temperature accurately reaches the preset value and remains constant. The entire device is used in continuous gold and platinum plating production lines, providing a continuous and stable heating environment for the plating solution or workpiece, ensuring the quality and consistency of the plating layer. Furthermore, the heat insulation plate 105 effectively prevents heat loss, and the sealing plate 103 ensures the airtightness of the heating chamber 100, further improving the equipment's efficiency and safety. Throughout the operation, the user can monitor and adjust parameters at any time through the controller 200 to adapt to different production process requirements.
