[0028] The utility model provides a conductive device for cathode conduction of a horizontal electroplating line.

[0029] Reference Figures 1 to 2 In an embodiment of the present invention, a conductive device for cathode conduction in a horizontal electroplating line includes:

[0030] A conductive oil tank assembly 10, wherein the conductive oil tank assembly 10 is provided with conductive oil;

[0031] a cathode assembly 20, the cathode assembly 20 being used to connect to an anode component of a power source to generate current;

[0032] A conductive slider assembly 30 is disposed on a horizontal electroplating fixture. The conductive slider assembly 30 is disposed in the conductive oil tank assembly 10 and immersed in the conductive oil. The conductive slider assembly 30 is electrically connected to the cathode assembly 20 and is used to transmit current to the horizontal electroplating fixture, so that the circuit board on the horizontal electroplating fixture is charged.

[0033] The reflux mechanism 40 includes an oil collecting tank 41 and a reflux component 42. The oil collecting tank 41 is used to store conductive oil. The conductive oil tank component 10 is connected to the oil collecting tank 41 through the reflux component 42 to form a circulation path for the conductive oil in the oil collecting tank 41 to circulate with the conductive oil in the conductive oil tank component 10.

[0034] The present invention is a conductive device for cathode conduction in a horizontal electroplating line. Its main components include a conductive oil tank assembly 10, a cathode assembly 20, a conductive slider assembly 30, and a reflow mechanism 40. The conductive oil tank assembly 10 is filled with conductive oil to create a conductive medium environment. The cathode assembly 20 is connected to the anode of the power supply, forming part of the current loop. The conductive slider assembly 30 is mounted on a horizontal electroplating fixture and immersed in the conductive oil within the conductive oil tank assembly 10. The conductive slider assembly 30 is electrically connected to the cathode assembly 20 and is responsible for conducting current from the cathode assembly 20 to the horizontal electroplating fixture, thereby charging the circuit board. The reflow mechanism 40 includes an oil sump 41 and a reflow assembly 42. The oil sump 41 is used to store the conductive oil. The conductive oil tank assembly 10 is connected to the oil sump 41 via the reflow assembly 42, forming a circulation path for the conductive oil. Specifically, the anode of the power supply and the cathode assembly 20 form a current loop. The conductive slider assembly 30 is immersed in the conductive oil within the conductive oil tank assembly 10 and electrically connected to the cathode assembly 20. Current is transmitted through the conductive slider assembly 30 to the horizontal electroplating fixture, charging the circuit board. During operation, the conductive oil within the conductive oil tank assembly 10 may need to be replaced or replenished due to temperature fluctuations or other factors. The return assembly 42 creates a circulation path between the conductive oil tank assembly 10 and the oil sump 41. When the conductive oil needs to be replaced or replenished, the conductive oil in the oil sump 41 flows through the return assembly 42 into the conductive oil tank assembly 10, and vice versa, thereby recycling the conductive oil. This solution uses conductive oil as a medium to transmit current and utilizes the return mechanism 40 to recycle the conductive oil, ensuring stable current transmission and effective management of the conductive oil during the horizontal electroplating process. This approach not only improves electroplating efficiency, but also reduces resource waste, enhancing equipment reliability and maintenance efficiency. The core of the entire solution is the use of conductive oil as a medium during the electroplating process and the recycling of the conductive oil through the return mechanism 40. This helps maintain current stability and conductivity during the electroplating process, while reducing resource consumption and costs by recycling the conductive oil. Furthermore, this design reduces mechanical wear, increasing system reliability and service life.

[0035] Reference Figures 1 to 2 In an embodiment of the present invention, the conductive device further includes an oil supply mechanism 50 , which is connected to the conductive oil tank assembly 10 to provide conductive oil to the conductive oil tank assembly 10 .

[0036] In addition to the conductive oil tank assembly 10, the cathode assembly 20, the conductive slider assembly 30 and the return mechanism 40, the conductive device also includes an oil supply mechanism 50. The main function of the oil supply mechanism 50 is to provide new conductive oil from the outside to the conductive oil tank assembly 10 to ensure the continuous supply of conductive oil and the normal operation of the system. Specifically, the anode component of the power supply forms a current loop with the cathode assembly 20. The conductive slider assembly 30 is immersed in the conductive oil in the conductive oil tank assembly 10 and is electrically connected to the cathode assembly 20. The current is transmitted to the horizontal electroplating fixture through the conductive slider assembly 10 to charge the circuit board. The conductive oil in the conductive oil tank assembly 10 flows into the oil collecting tank 41 through the return assembly 42, and then returns to the conductive oil tank assembly 10 through the return assembly, completing a cycle. When the conductive oil in the conductive oil tank assembly 10 needs to be replenished or replaced, the oil supply mechanism (50) provides new conductive oil to the conductive oil tank assembly. The existence of the oil supply mechanism ensures that the conductive oil tank assembly always has sufficient conductive oil supply, and the normal operation of the system can be maintained even in the case of long-term operation or large-scale consumption. Conductive oil replenishment maintains its purity, thereby improving electroplating quality and efficiency. Automatic replenishment of the conductive oil by the oil supply mechanism reduces the frequency of manual oil addition, simplifies maintenance, and improves equipment reliability and ease of operation. It is understood that the oil supply mechanism can be a pump-type oil supply mechanism, powered by a pump to deliver the conductive oil from the oil reservoir to the conductive oil tank assembly. Common pump types include centrifugal pumps, gear pumps, and plunger pumps. Alternatively, a compressed air oil supply mechanism can utilize compressed air pressure to press the conductive oil from the oil reservoir into the conductive oil tank assembly. The oil supply rate can be controlled by adjusting the compressed air pressure. It is understood that the connection between the oil supply mechanism 50 and the conductive oil tank assembly 10 is not necessarily limited to the oil inlet. The oil supply mechanism 50 can also be connected using other methods that ensure efficient delivery of the conductive oil to the conductive oil tank assembly. For example, the oil supply mechanism 50 can be connected to the conductive oil tank assembly 10 through a top opening, a side port, or other specially designed delivery path. It will be understood that the oil supply mechanism 50 is connected to the conductive oil tank assembly 10 via one or more oil supply pipes. One end of the oil supply pipe is connected to the oil supply mechanism 50, and the other end is connected to the conductive oil tank assembly 10. A valve is installed in the oil supply pipe to control the flow of conductive oil. The valve can be a manual valve, an electric valve, or a pneumatic valve, etc., to ensure that conductive oil can flow from the oil supply mechanism 50 into the conductive oil tank assembly 10 and to close or adjust the flow when necessary. The oil supply mechanism 50 can be connected to the conductive oil tank assembly 10 via a flange connection. The flange connection includes a pair of flanges, one of which is installed at the outlet of the oil supply mechanism 50 and the other is installed at the inlet of the conductive oil tank assembly 10. The flange connection is fixed by bolts to ensure that conductive oil can flow from the oil supply mechanism 50 into the conductive oil tank assembly 10.

[0037] Reference Figures 1 to 2 In an embodiment of the present invention, the reflux mechanism 40 further includes an overflow component 43, the overflow component 43 having an overflow port, the overflow component 43 being connected to the conductive oil tank component 10 through the overflow port, the conductive oil tank component 10 being connected to the oil collecting tank 41 through the overflow component 43, and the conductive oil tank component 10 having a preset volume. When the liquid volume in the conductive oil tank component 10 exceeds the preset volume, the conductive oil in the conductive oil tank component 10 can flow into the oil collecting tank 41 through the overflow component 43.

[0038] The overflow assembly 43 enables automatic overflow and circulation of the conductive oil, ensuring that the liquid volume within the conductive oil tank assembly 10 does not exceed the preset volume limit. The overflow assembly 43 automatically handles conductive oil that exceeds the preset volume, avoiding the need for manual intervention or monitoring. Setting a preset volume ensures that the liquid within the conductive oil tank assembly 10 does not exceed the safety limit, thereby preventing safety hazards caused by overflow. The conductive oil is recycled and the conductive oil is reintroduced from the oil collection tank 41 into the conductive oil tank assembly 10 through a reflux mechanism, thereby improving the utilization rate of the conductive oil. It is understandable that the overflow assembly 43 can be connected to the conductive oil tank assembly 10 and the oil collection tank 41 via a pipeline. The pipeline between the overflow port and the conductive oil tank assembly 10 ensures that the conductive oil can flow smoothly into the overflow assembly. The pipeline between the overflow assembly 43 and the oil collection tank 41 ensures that the conductive oil can flow into the oil collection tank. It is understood that the overflow assembly 43 is connected to the conductive oil tank assembly 10 via a first quick connector, which is installed at the overflow port of the overflow assembly 43 and ensures that the conductive oil can flow smoothly from the conductive oil tank assembly 10 into the overflow assembly 43. The overflow assembly 43 is connected to the oil collection tank 41 via a second quick connector, which is installed at the outlet of the overflow assembly 43 and ensures that the conductive oil can flow smoothly from the overflow assembly 43 into the oil collection tank 41.

[0039] Reference Figures 1 to 2 In an embodiment of the present invention, the reflux mechanism 40 further includes a filter element, which is disposed in the flow channel between the oil collecting tank 41 and the overflow port, and is used to filter the conductive oil flowing from the overflow port into the oil collecting tank 41.

[0040] The inclusion of a filter in the return mechanism 40 ensures the purity of the conductive oil during circulation, thereby improving electroplating quality and system reliability. Impurities such as copper shavings may be generated during the electroplating process. If left untreated, these impurities can affect the plating quality. Removing impurities by filtering can extend the lifespan of the conductive oil and reduce replacement frequency. Clean conductive oil reduces system blockage and wear, improving system stability and reliability. The purified filtered conductive oil improves the uniformity and quality of the electroplated layer. This reduces maintenance work caused by impurities and lowers maintenance costs. Clean conductive oil reduces corrosion and wear on equipment, extending its service life. Specifically, during operation, the conductive oil flowing into the oil sump is filtered by the filter assembly 44 to remove impurities such as copper shavings. The cleaned conductive oil then returns to the conductive oil sump assembly 10 through the return assembly 42, completing the cycle. It will be appreciated that the filter assembly 44 can be a static filter or a dynamic filtration system to capture and remove copper shavings from the conductive oil. Static filters may include a screen or filter element, while dynamic filtration systems may include a pumping system to ensure that the conductive oil remains clean after multiple circulations.

[0041] Reference Figures 1 to 2 In the embodiment of the present invention, the conductive slider assembly 30 includes a first conductive slider 31 and a second conductive slider 32 spaced apart from the first conductive slider 31. The first conductive slider 31 and the second conductive slider 32 are respectively configured on the corresponding horizontal electroplating fixture. The cathode assembly 20 includes a first cathode member 21 and a second cathode member 22. The first conductive slider 31 and the second conductive slider 32 are respectively electrically connected to the first cathode member 21 and the second cathode member 22 in a one-to-one correspondence. The overflow assembly 43 includes a first overflow member 431 and a second overflow member 432. The reflux assembly 42 includes a first connecting member 421 and a second connecting member 422 to connect the pipe. The first connecting member 421 has a first connecting member. interface, a second connection port and a third connection port, the second connecting member 422 has a fourth connection port and a fifth connection port, the conductive oil tank assembly 10 includes at least a first conductive oil tank 11 and a second conductive oil tank 12, the cathode assembly 20 is electrically connected to the first conductive slider 31, one end of the first overflow member 431 is connected to the first conductive oil tank 11, the other end of the first overflow member 431 is connected to the fourth connection port, the fifth connection port is connected to the first connection port through the connecting pipe, one end of the second overflow member 432 is connected to the second connection port, the other end of the second overflow member 432 is connected to the second conductive oil tank 12, and the third connection port is connected to the reflux port of the oil collecting tank 41 through the connecting pipe.

[0042] This invention discloses a conductive device for cathode conduction in a horizontal electroplating line, comprising multiple conductive oil tanks, a conductive slider assembly, an overflow assembly, and a return assembly, as well as the connection methods therebetween. The conductive slider assembly 30 comprises a first conductive slider 31 and a second conductive slider 32, spaced apart and respectively positioned on corresponding horizontal electroplating fixtures. The overflow assembly 43 comprises a first overflow member 431 and a second overflow member 432. The return assembly comprises a first connecting member 421, a second connecting member 422, and a connecting pipe. The conductive oil tank assembly 30 comprises at least a first conductive oil tank 11 and a second conductive oil tank 12. The cathode assembly 20 is electrically connected to the first conductive slider 31. The use of two conductive sliders ensures a more even distribution of current across the electroplating fixture, thereby improving the uniformity and quality of the electroplated layer. The combination of the first overflow member 431, the second overflow member 432, and the first connecting member 421 and the second connecting member 422 enables efficient circulation of the conductive oil. This design ensures that the conductive oil is fully filtered and treated during circulation, maintaining its purity. The first and second conductive oil tanks 11 and 12 provide redundancy. Even if one tank experiences a problem, the other can continue to operate, ensuring stable system operation. The separate design of individual components, such as the first conductive slider 31, the second conductive slider 32, the first overflow member 431, and the second overflow member 432, simplifies maintenance and overhaul. Each component can be inspected and maintained separately without shutting down the entire system. Specifically, the anode of the power supply forms a current loop with the cathode assembly 20. The first conductive slider 31 is electrically connected to the cathode assembly, and current is transferred through the first conductive slider 31 to the horizontal electroplating fixture, charging the circuit board. Conductive oil flows from the first conductive oil tank 11 through the first overflow member 431 into the oil collecting tank 41. One end of the first overflow member 431 is connected to the first conductive oil tank 11, and the other end is connected to the fourth connector. The fifth connector is connected to the first connector via a connecting pipe.

[0043] One end of the second overflow member 432 is communicated with the second connecting port, and the other end is communicated with the second conductive oil tank 12 .

[0044] The third connecting port is connected to the oil collecting tank 41 through a connecting pipe.

[0045] Reference Figures 1 to 2 In an embodiment of the present invention, the conductive device also includes a conductive oil storage sub-cylinder and a circulation pump. The circulation pump is arranged in the conductive oil storage sub-cylinder. The circulation pump is connected to the third connecting port and the oil collecting tank 41, and is used to drive the conductive oil in the oil collecting tank 41 and the conductive oil tank assembly 10 to circulate.

[0046] This solution adds a conductive oil storage sub-cylinder and a circulation pump to the existing conductive device to ensure efficient circulation of conductive oil within the system. The conductive oil storage sub-cylinder is used to store additional conductive oil to replenish the system's conductive oil needs. The circulation pump is located within the conductive oil storage sub-cylinder and drives the conductive oil to circulate between the oil sump 41 and the conductive oil tank assembly 10. Specifically, conductive oil flows from the conductive oil tank assembly 10 through the overflow assembly 43 into the oil sump 41. Within the oil sump 41, the conductive oil enters the conductive oil storage sub-cylinder, where the circulation pump is located, through a third connection port. The circulation pump drives the conductive oil from the storage sub-cylinder back through the third connection port to the oil sump 41, and further back to the conductive oil tank assembly 10 through the return assembly 42. The conductive oil in the conductive oil storage sub-cylinder can be replenished to the conductive oil tank assembly 10 by the circulation pump, ensuring an adequate supply of conductive oil. By providing the conductive oil storage sub-cylinder, an adequate supply of conductive oil is ensured, allowing for timely replenishment even when the conductive oil in the conductive oil tank assembly 10 becomes depleted. The circulation pump can actively drive the circulation of the conductive oil, ensuring its uniform distribution throughout the system. The combined design of the conductive oil storage sub-cylinder and the circulation pump enhances system stability and ensures a continuous supply of conductive oil during the electroplating process. Driven by the circulation pump, flow interruptions caused by insufficient or poor conductive oil flow are prevented. It is understood that one or more pipes can be used to directly connect the circulation pump to the conductive oil tank assembly 10 and the oil collection tank 41. Alternatively, a quick connector can be used to connect the circulation pump to the conductive oil tank assembly and the oil collection tank.

[0047] Reference Figures 1 to 2 In an embodiment of the present invention, the conductive device further includes a cooling mechanism, which is arranged in the conductive oil storage sub-cylinder, and is driven and connected to the circulating pump, and is used to cool the conductive oil that flows back into the conductive oil storage sub-cylinder.

[0048] The cooling mechanism typically includes a cooling device, such as a heat exchanger or chiller, that can reduce the temperature of the conductive oil through water cooling, air cooling, or other methods. The cooling mechanism is connected to the circulating pump, which allows the circulating pump to promote the flow of the conductive oil, thereby effectively exchanging heat. The conductive oil storage sub-tank temporarily stores the conductive oil, where it can be processed by the cooling mechanism. When the conductive oil returns from the electroplating area to the storage sub-tank, the cooling mechanism cools it down before it is re-delivered to the electroplating area via the circulating pump. During the electroplating process, the conductive oil heats up due to the current. Excessive temperatures can affect electroplating quality and equipment stability. Therefore, this solution incorporates a cooling mechanism within the conductive device, located within the conductive oil storage sub-tank. The cooling mechanism is connected to the circulating pump and is used to cool the conductive oil returning to the storage sub-tank. This cooling mechanism ensures that the conductive oil temperature remains within the optimal range, improving electroplating quality and equipment reliability. It is understood that various cooling methods can be used, such as air cooling, water cooling, or refrigerant cooling, and the most appropriate cooling method should be selected based on the specific situation. Alternatively, a combination of cooling methods can be employed, such as initial cooling with air cooling followed by further cooling with water cooling, to improve cooling efficiency. The cooling mechanism can include cooling coils installed within the storage sub-tank. These coils cool the conductive oil using cooling water or another cooling medium. The conductive oil storage sub-tank typically contains a container with sufficient capacity to store the conductive oil. Corrosion-resistant materials, such as stainless steel or specialized plastics, are typically selected to accommodate the chemical properties of the conductive oil.

[0049] Reference Figures 1 to 2 In an embodiment of the present invention, the conductive device further includes a temperature control mechanism, which is located in the conductive oil tank assembly 10 and at least partially immersed in the conductive oil, so as to measure the temperature of the conductive oil in the conductive tank assembly 10.

[0050] During the electroplating process, the temperature of the conductive oil significantly impacts the quality and efficiency of the plating process. Precise temperature control helps maintain the optimal condition of the conductive oil, thereby ensuring consistent and high-quality electroplating. A temperature control mechanism, directly immersed in the conductive oil, monitors the oil's temperature changes in real time. Designed to be at least partially submerged, the temperature control mechanism accurately measures the oil's actual temperature. This ensures accurate temperature measurement and prevents environmental influences. A temperature control mechanism typically includes the following components: A temperature sensor: Common temperature sensors include RTDs, thermocouples, or thermistors, which directly measure the temperature of the conductive oil. A signal transmission line: This transmits the temperature signal to a control system or display instrument. The temperature sensor is typically mounted within a protective sleeve, which not only protects the sensor from impurities in the conductive oil but also ensures optimal contact with the oil. The temperature control mechanism can be secured within the conductive oil tank assembly using threaded or flanged connections to prevent movement or damage due to fluid flow.

[0051] Reference Figures 1 to 2 In an embodiment of the present invention, the conductive device further includes a protective shell 60 , which is sleeved on the cathode assembly 20 , and the inner layer of the protective shell 60 is in contact with the outer layer of the cathode assembly 20 .

[0052] A protective housing 60 is added to the conductive device to protect the cathode assembly 20 from external interference and damage. The protective housing 60 prevents the ingress of foreign matter (such as dust and impurities) that could affect the electroplating effect. In humid environments, the protective housing 60 protects the cathode assembly 20 from moisture or corrosion, thereby extending its service life. The protective housing 60 prevents operators from accidentally touching the live cathode assembly, improving safety. The protective housing 60 prevents conductive oil or other conductive substances from coming into contact with the cathode assembly, thereby avoiding short-circuit accidents. The protective housing 60 reduces friction between the cathode assembly 20 and other components, thereby extending the service life of the cathode assembly. The design of the protective housing 60 facilitates maintenance and replacement of the cathode assembly 20. It is understood that the protective housing 60 can completely enclose the cathode assembly to prevent the ingress of foreign matter. The protective housing 60 can be semi-enclosed, with certain ventilation openings or observation windows for easy inspection and maintenance. The protective housing 60 can be designed to be removable to facilitate replacement or maintenance of the cathode assembly. It is understood that the protective housing 60 can be made of stainless steel: it is corrosion-resistant, has high strength, and is suitable for use in humid environments. Alternatively, aluminum alloys are lightweight and corrosion-resistant, making them suitable for applications requiring weight reduction. Alternatively, engineering plastics such as polycarbonate (PC) and polyamide (PA) offer excellent insulation and corrosion resistance.
