Description

Technical Field

[0001] The invention relates to the technical field of silver plating equipment, in particular to a silver plating equipment for the surface of an aluminum alloy part. Background Art

[0002] With the development of manufacturing industry, especially in the fields of high precision and high standards, such as electronics, automobiles, aviation, medical equipment, power grid devices and other related fields, electroplating technology, especially silver plating technology, plays a vital role. Silver has excellent conductivity and corrosion resistance, making it the first choice for many applications. In order to meet the increasingly stringent quality requirements and environmental protection standards, the existing electroplating technology is developing towards automation, intelligence and environmental protection.

[0003] The electroplating technology on the market currently focuses on increasing the speed of electroplating and reducing costs. Common silver electroplating equipment usually includes a simple electroplating tank, a basic temperature control system, and a manual workpiece suspension system. These systems often lack fine temperature control and automated object handling mechanisms, which makes it challenging to ensure the uniformity and quality of the coating. In addition, traditional electroplating equipment often does not include an integrated detection mechanism, which means that the coating quality control depends on the later quality inspection steps, increasing production costs and time.

[0004] With respect to the above-mentioned related technologies, the temperature control system in the prior art is usually unable to accurately adjust the temperature of the electroplating tank, which may result in uneven coating and insufficient adhesion for the silver plating process that requires fine temperature control. The hanging and movement of the workpiece are inconvenient, which is not only inefficient, but also difficult to maintain the consistency of the coating. There is a lack of post-detection and quality control, and there is no integrated online detection system, which makes it impossible to monitor and adjust the electroplating process, which may lead to low production efficiency and coating quality problems such as bubbles, peeling, scratches, etc. There is a lack of automatic rework processing function. Therefore, a technician in this field provides an aluminum alloy surface silver plating device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a device for silver-plating the surface of an aluminum alloy part to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The testing mechanism and the electroplating mechanism are tightly connected.

[0008] By adopting the above technical solution, firstly, the temperature control mechanism cooperates with the pipeline system and the spiral air duct to achieve precise temperature control. The tight connection between the temperature control mechanism and the electroplating mechanism ensures the effective transfer of heat energy and a stable operating environment. The electroplating mechanism is located in the temperature control mechanism, and hydraulic and elastic elements are used to achieve stable suspension and dynamic movement of the workpiece. The connection between the electroplating tank and the temperature control tube further enhances the control of the plating solution temperature, thereby improving the uniformity and quality of the plating layer. The repair plating mechanism is tightly connected to the electroplating mechanism to achieve surface grinding and finishing of the electroplated workpiece, thereby improving the surface finish and plating quality of the product. The integrity of the layer, the refill tube and the refill one-way valve ensure the accurate supply of supplementary materials and prevent backflow. The cleaning mechanism provides necessary surface preparation and cleaning for the workpiece before and after electroplating through cleaning operations. The detection mechanism is tightly connected to the electroplating mechanism to achieve accurate detection of the thickness and uniformity of the electroplating layer. At the same time, it can detect defects on the plating surface due to poor surface treatment of aluminum alloy or improper operation, such as bubbles, peeling, scratches, etc., and perform automatic rework processing, thereby improving work efficiency, reducing energy consumption and improving productivity, thereby meeting the high standards for silver-plated products in industrial production.

[0009] Furthermore, the temperature control mechanism includes a temperature control box, a temperature control board, a liquid inlet pipe, a liquid outlet pipe, a connecting pipe, a temperature control tube, a fan, a liquid pump, a liquid storage tank and a temperature sensor.

[0010] By adopting the above technical scheme, the temperature control box is tightly connected to the electroplating mechanism to form a closed temperature control environment, wherein the temperature control board and the temperature control box are connected and fixed to ensure the stability of the temperature control board and facilitate maintenance. A spiral air duct is provided in the temperature control box, which is connected to the dustproof air outlet, which not only improves the air flow efficiency of the air duct, but also effectively prevents dust from entering and protects internal components. The liquid inlet pipe and the liquid outlet pipe are tightly connected to the temperature control box and connected to the temperature control tube. One part of the temperature control tube is arranged in the air duct, and the other part extends to the inside of the electroplating mechanism.

[0012] By adopting the above technical solution, the liquid inlet pipe and the liquid outlet pipe are arranged in a serpentine shape. This structure can effectively increase the total length and surface area of ​​the pipe, thereby improving the heat exchange efficiency and enabling the liquid to better regulate the temperature during the flow process. Specifically, the liquid inlet pipe and the liquid outlet pipe are staggered with the temperature control pipe in the temperature control box to form preheating convection and direct temperature control of the pipe. The liquid inlet pipe and the liquid outlet pipe are respectively provided with an upper liquid inlet and an upper liquid outlet located at the upper end of the pipe, and a lower liquid inlet and a lower liquid outlet located at the lower end of the pipe, allowing the liquid to flow evenly over the entire length of the pipe, promoting the efficiency of fluid dynamics through gravity and pressure difference, and the design of the temperature control pipe. The design is a quasi-rectangular ring, which helps to maximize the layout of the pipeline in a smaller space and increase the contact area with the inlet and outlet liquid pipes, thereby more effectively exchanging heat. The temperature control tubes are connected by connecting pipes, which are located at the quasi-rectangular corner ends of the temperature control tubes and are set diagonally. The flow path length flowing in from the diagonal is consistent, ensuring the uniform distribution of liquid in the pipeline and balanced heat transfer. The silver plating equipment can effectively control the thermal management of the silver plating process while maintaining the balance of liquid temperature.

The tight connection ensures stable structural support and good heat exchange performance, and keeps the temperature of the electroplating solution within an ideal range. The rotating assembly includes two sets of diagonally arranged rotating motors, rotating rods, rotating wheels and transmission belts.

This arrangement of the rotating assembly ensures uniform rotation of the electroplated object in the electroplating tank, thereby achieving a uniform electroplating effect. The positive plug is tightly connected to the hanger assembly and is connected to the external electrical positive electrode through an electrical conductor to ensure stable input of current. The first hydraulic cylinder in the hanger assembly is connected to the hanger transmission so that it can be vertically lowered or raised, thereby providing a stable and adjustable hanging force. The rotating motor drives the rotating rod through the transmission The dynamic belt transmits power evenly to the impeller and the inert box, which promotes the circulation of the plating solution on the one hand and releases the inert gas to prevent oxidation on the other hand, which can help release bubbles in the solution and reduce the accumulation of oxygen. This dynamic flow helps prevent oxygen from accumulating on the surface of the electrode, thereby reducing oxidation and the formation of bubbles. Injecting inert gases (such as nitrogen or argon) above the plating tank can form a protective layer to isolate oxygen in the air from contact with the plating solution, which not only helps to reduce the dissolution of oxygen, but also stabilizes the chemical properties of the plating solution. The convection formed by the rotating components maintains the uniformity of the plating environment, thereby achieving uniform plating of the workpiece, improving product quality and production efficiency. The combination of constant temperature control in the plating tank and the continuous rotation of the object ensures the uniformity and adhesion of the plating layer, reduces defects and the need for reprocessing, and the overall design significantly improves the reliability of the plating process and the output efficiency of the production line by optimizing the interaction and coordination of each component.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The liquid inlet and outlet pipes are arranged in a serpentine shape. This structure can effectively increase the total length and surface area of ​​the pipe, thereby improving the heat exchange efficiency and enabling the liquid to better regulate the temperature during the flow process. Specifically, the liquid inlet and outlet pipes are arranged in an alternating manner with the temperature control pipe in the temperature control box to form preheating convection and direct temperature control of the pipe. The liquid inlet and outlet pipes are respectively provided with an upper liquid inlet and an upper liquid outlet located at the upper end of the pipe, and a lower liquid inlet and a lower liquid outlet located at the lower end of the pipe, allowing the liquid to flow evenly over the entire length of the pipe, promoting the efficiency of fluid dynamics through gravity and pressure difference.

The temperature control pipes are connected by connecting pipes, which are located at the rectangular corner ends of the temperature control pipes and are arranged diagonally. The flow path length of the flow in from the diagonal is consistent, ensuring the uniform distribution of the liquid in the pipe and the balanced transfer of heat.

[0025] 2. The hanger assembly is placed above the temperature control box and is tightly connected to the electroplating tank.

The rotating assembly includes two sets of diagonally arranged rotating motors, rotating rods, rotating wheels and transmission belts. These parts are connected by transmission to achieve uniform and continuous rotation in the plating solution. This setting of the rotating assembly ensures uniform rotation of the electroplated object in the electroplating tank, thereby achieving a uniform electroplating effect. The positive plug is tightly connected to the hanger assembly and is connected to the external electrical positive electrode through an electrical conductor to ensure stable input of current. The first hydraulic cylinder in the hanger assembly is connected to the hanger transmission so that it can be vertically lowered or raised, thereby providing a stable and adjustable hanging force. The rotating motor drives the rotating rod to move the moving wheel through the transmission belt. The force is evenly transmitted to the impeller and the inert box, which promotes the circulation of the plating solution on the one hand and releases the inert gas to prevent oxidation on the other hand, which can help release bubbles in the solution and reduce the accumulation of oxygen. This dynamic flow helps prevent oxygen from accumulating on the surface of the electrode, thereby reducing oxidation and the formation of bubbles. Injecting an inert gas (such as nitrogen or argon) above the plating tank can form a protective layer to isolate oxygen in the air from contact with the plating solution, which not only helps to reduce the dissolution of oxygen, but also stabilizes the chemical properties of the plating solution. The convection formed by the rotating components maintains the uniformity of the plating environment, thereby achieving uniform plating of the workpiece, improving product quality and production efficiency. The combination of constant temperature control in the plating tank and the continuous rotation of the object ensures the uniformity and adhesion of the plating layer, reduces defects and the need for reprocessing, and the overall design significantly improves the reliability of the electroplating process and the output efficiency of the production line by optimizing the interaction and coordination of each component.
