Abstract
Description
Technical Field
[0001] The present invention relates to the field of electroplating, and in particular to an electroplating tank condensed water induction processing mechanism. Background Art
[0002] Electroplating utilizes the principle of electrolysis to deposit a thin layer of metal on the surface of a workpiece. Temperature control of the plating bath's liquid, due to its fluctuating parameters, directly affects instrument monitoring and, consequently, the quality of electroplating. Monitoring parameters often needs to be done every 2 or 1 hour to ensure timely adjustment to the standard value for stable electroplating. Different plating materials and additives dictate different temperature requirements for the plating bath. For example, bright nickel plating requires a bath temperature between 55-65°C, while silver plating is maintained at around 10°C. During electroplating, the bath is typically heated directly by equipment, often neglecting to maintain the correct temperature within the bath itself. Plating baths are typically plastic and lack self-heating properties. When the bath is first heated, the bath temperature at the bath opening and bottom differs significantly, creating a significant temperature difference. This, in turn, results in uneven plating quality between the bath opening and bottom. If the bath temperature reaches a critical upper or lower limit, controlling the bath temperature at both the bath opening and bottom becomes crucial to electroplating quality.
[0003] In addition, during low-temperature electroplating, since the temperature in the electroplating workshop is usually high, when the water vapor in the hot air encounters the colder electroplating tank, it will condense into a large amount of condensed water on the outer surface of the electroplating tank. Most of the electroplating tanks currently on the market adopt an outward-turned structure design for the slots, and condensed water will accumulate at the slots. During long-term production, the condensed water will enter the electroplating tank from the slots, and the condensed water will carry dust in the air during the condensation process, causing the concentration of the electroplating solution to decrease and introducing new impurities, thereby affecting the quality of electroplating. If the condensed water outside the tank flows down to the outside, it will also cause the electroplating environment to be humid, affecting the accurate detection of other electroplating instruments. In severe cases, it may even affect the normal operation of the electroplating equipment, posing a hidden danger. Summary of the Invention

[0009] An annular groove is provided around the periphery of the groove body along the notch. The length of the profile 1 matches the length and width of the notch. One side of the profile 1 is embedded in the groove and fixed on the notch.
[0010] Furthermore, the two adjacent ends of the profile 1 are fixedly connected with adapters, the adapter is provided with two plugs, the plugs are provided with threaded holes, and the corresponding positions of the profile 1 are also provided with threaded holes. The plugs are inserted into the profile 1 and fixed by screws.
[0011] Furthermore, adjustable support feet are provided under the four corners of the tray, the adjustable support feet are connected to the tray through threads, and washers are provided between the adjustable support feet and the tray.
[0012] Furthermore, the edge of the tray extends a distance beyond the bottom edge of the groove.
[0013] Furthermore, a rubber support is provided between the trough body and the tray, and sleeve grooves are provided at the four lower corners of the trough body, and the rubber support is sleeved and fixed in the sleeve grooves.
[0014] Furthermore, a drain valve and a flange interface are provided on the side of the trough body, and the ultrasonic transducer is arranged at the flange interface.
[0015] Furthermore, the tank body is formed by integral injection molding, and the wall thickness of the tank body is 20 mm.
[0016] A method for induction treatment of condensed water in the electroplating tank described above comprises the following steps:
[0017] 1) Use triangular tubes to form the outer facade of the notch profile, which is inclined to drain the condensed water downward;
[0018] 2) Use V-shaped or inverted V-shaped collecting troughs with inclined sidewalls to drain condensed water downward;
[0019] 3) Set up a V-shaped hole and let the condensed water flow through the hole. Connect the electrode rod to generate signal induction, which is then received by the controller. Ultrasonic vibration is used to accelerate the collection of condensed water, or to start the heating of the side wall, or to deal with the electroplating treatment of the environmental impact of the condensed water.
[0020] The present invention has the beneficial effects:
[0021] 1. The notch is provided with a profile 1 and a connecting structure of the adapter block and a profile 2 at the bottom of the tank body. The cross-section of the profile 1 is a triangular tube, and is made of aluminum alloy with good rigidity. It has a built-in heating film, forming a stable reinforcement structure of the mouth and the bottom that is detachable. The built-in heating film can be controlled by the controller to heat the notch and the bottom of the tank to solve the problem of constant temperature of the notch and the bottom of the tank during electroplating. It can realize the self-heating of the device body and the auxiliary function of the electroplating liquid, so that the electroplating liquid at the notch and the bottom of the tank is kept at the same temperature, avoiding a large temperature difference between the electroplating liquid at the bottom and the notch, and ensuring the electroplating tank. The temperature of the plating liquid is stable and uniform. In addition, since the profile is a triangular tube, the outer facade of the notch profile is an inclined surface, combined with the inclined V-shape and inverted V-shape design, while achieving the reinforcement and heat generation of the trough structure, it also allows the condensed water on the end face of the notch to be smoothly discharged along the side wall to the tray for collection, reducing the accumulation of condensed water at the notch, further ensuring the temperature environmental factors of the notch surface, and preventing the condensed water from entering the tank to affect the concentration of the plating solution and the introduction of new impurities. A variety of effects can be achieved with a simple structure. The graphene heating film used inside has fast heat transfer, uniform heat generation, and is controllable, making it very flexible to use.
[0022] Flange interfaces are located on both sides of the tank, and ultrasonic transducers are installed at these interfaces. These transducers can be controlled and driven by a controller to oscillate and stir the plating solution, further ensuring uniform temperature and concentration, thereby improving the quality of subsequent coatings. Ultrasonic waves can also be used to clean impurities adhering to the inner walls of the plating tank, reducing the difficulty of subsequent cleaning.
[0023] 2. Reinforcement ribs 1 and 2 are provided on the trough body. While strengthening the overall structure of the trough body, they also have a drainage effect, draining the condensed water on the outer side of the trough body into the water collection tray for collection, so as to avoid the dampness of the trough body or the ground caused by the condensation water, or affecting the accurate use of other electronic equipment.

[0033] Please refer to Figure 1 、 2 3. A condensate induction treatment mechanism for an electroplating tank, comprising a tank body 1 and a notch at the top, the tank body 1 being provided with a condensate induction treatment mechanism and a constant temperature mechanism, the constant temperature mechanism comprising a profile 1 2 and a profile 2 3, a ring-shaped groove 16 being provided on the periphery of the notch, the length of the profile 1 2 matching the length and width of the notch, two adjacent profiles 2 being connected by an adapter 4, the adapter 4 being provided with two plugs 41, the plugs 41 matching and plugging with the pipe mouths of the profile 1 2, the plugs 41 being provided with threaded holes, the pipe mouths of the profile 1 2 being provided with threaded holes at corresponding positions, the plugs 41 being inserted into the profile 1 2 and being fixed by screws to achieve connection and fixation of adjacent profiles, one side of the profile 1 2 being embedded and fixed in the groove 16, and then connected by the adapter 4, the profiles 1 2 being spliced into a rectangular frame and fixed in the groove 16 on the notch, the profile 1 2 being detachably installed at the notch, which is convenient for replacement and maintenance, while increasing the structural stability of the notch and avoiding deformation of the notch.
[0034] The slot is set up, and the cross-sectional profile of its profile one is a triangular tube, and it is made of aluminum alloy, has good rigidity, and has a built-in heating film, forming a reinforcement structure of the mouth that is both detachable, and the built-in heating film can be controlled by a controller to heat the slot to solve the problem of constant slot temperature during electroplating, so as to achieve the same temperature of the plating liquid at the slot, avoid large temperature differences of the plating liquid at the slot, and ensure that the temperature of the plating liquid in the plating tank is stable and uniform. In addition, since the profile is a triangular tube, the facade of the slot profile is an inclined surface, while achieving the reinforcement and heating of the tank structure, it also allows the condensed water on the end face of the slot to smoothly flow down along the side wall, reducing the accumulation of condensed water at the slot, further ensuring the temperature environmental factors of the slot surface, and at the same time preventing the condensed water from entering the tank and affecting the concentration of the plating solution and introducing new impurities, achieving multiple effects with a simple structure, and the graphene heating film used inside has fast heat transfer, uniform heat, and controllable application, and is very flexible.
[0035] Profile 2 3 is evenly laid and fixed under the outer bottom of the trough body 1. Profile 1 2 and Profile 2 3 are both made of aluminum alloy and are hollow tubular with good rigidity. They strengthen the strength of the notch and the bottom of the trough. The reinforced trough body is firm and reliable and not easy to deform. Profile 1 2 and Profile 2 3 are both bonded with heating films on the inner walls of the tubes. The heating films are graphene heating films. The graphene heating films have the advantages of fast thermal conductivity, small heating temperature difference and low energy consumption. Profile 1 2 heats the notch and Profile 2 3 heats the bottom of the trough to achieve consistent temperature at the bottom and the notch, ensuring that the temperature of the plating solution in the trough is uniform and stable, avoiding large temperature difference between the plating solution at the bottom and the notch, and improving the quality of electroplating.
[0036] The plating tank is also provided with an ultrasonic transducer (not shown in the figure, the ultrasonic transducer is existing technology and will not be described here one by one). While heating, the ultrasonic transducer can be started to radiate ultrasonic waves into the plating solution through the wall of the plating tank. The plating solution is irradiated by ultrasonic waves, and the microbubbles therein keep vibrating under the action of sound waves, thereby stirring the plating solution and making the solution concentration uniform. At the same time, it further ensures the uniformity of the temperature of the plating solution and improves the quality of electroplating.
[0037] Please refer to Figure 2 、 3 4. The condensation water induction processing mechanism includes a V-shaped reinforcing rib 11, an inverted V-shaped reinforcing rib 2 12, an electrode rod 7, and a tray 5. The two outer sides of the tank body 1 are respectively provided with a reinforcing rib 11 and a reinforcing rib 2 12, which are arranged on the upper and lower outer walls of the tank body to form a drainage structure for the liquid, which is also a reinforcement structure. A small hole is opened at the bottom of the reinforcing rib 11, and two electrode rods 7 are arranged outside the small hole and fixed on the reinforcing rib 1 11. The two electrode rods 7 are connected to a current sensor 71, and the controller is connected to the current signal sensor 71 (the electrode rod and the sensor are electronic products of the prior art). A tray 5 is also provided under the tank body 1, and the edge of the tray 5 extends out of the distance of one end of the tank bottom. The cold water generated on the outer surface of the electroplating tank The condensed water is drained into the tray 5 through the reinforcing rib 11 and the reinforcing rib 2 12. When the condensed water flows through the bottom of the reinforcing rib 11, the two electrode rods 7 are connected to conduct electricity to form an electrical circuit, so that the current sensor 71 generates an electrical signal to the controller. After detecting the signal, the controller starts the ultrasonic transducer and accelerates the flow of condensed water into the tray 5 through vibration, thereby reducing the accumulation of condensed water on the electroplating tank, or performing early warning control of various electronic instruments, that is, starting other electronic devices or instruments for response use, or making fine adjustments to the electroplating parameters, while avoiding long-term moisture of the equipment and the ground, affecting the operation of the equipment, and improving production safety. The simple structure can achieve reinforcement, drainage, sensing of condensed water and electroplating treatment response to the condensed water environment.
[0038] During early warning processing, electrodes and current sensors are installed at the bottom of each rib 11. This allows for separate detection of condensation around the plating tank, enabling differentiated early warning control for each side, further achieving precise control. For example, if a signal is generated on only one side, it indicates that the electrical equipment or temperature on that side requires minor adjustments, while the electrical equipment or temperature on other sides can remain unchanged.
[0039] In addition, the cross-sectional profile of profile 12 is triangular. After profile 12 is embedded in groove 16, the outer side of the groove is an inclined surface. Compared with the outward-turned groove design of the electroplating tanks on the market (with a larger top area, which is easy to accumulate condensed water), it has the advantage of not easily accumulating condensed water. Condensed water is formed at the groove and flows down along the inclined surface. In combination with the V-shaped reinforcement rib 1 and the inverted V-shaped reinforcement rib 2, the condensed water at the end face of the groove is discharged along the outer wall to the tray 5 for collection, further ensuring the temperature environment of the groove surface, while also ensuring the quality of electroplating.
[0040] Please refer to Figure 2 、 5 , the four corners of the trough body 1 are provided with sleeve grooves 17, and a rubber support 8 is provided between the trough body 1 and the tray 5. The rubber support 8 is sleeved and fixed in the sleeve groove 17. The rubber support 8 has a good shock isolation effect, which can prevent the tray 5 under the trough body from vibrating and causing displacement or condensation water to spill. Adjustable support feet 6 are provided under the four corners of the tray 6, and a gasket 61 is provided between the adjustable support feet 6 and the tray 5. The adjustable support feet 6 are connected to the tray 5 through threads. By adjusting the support feet 6, the height of the four corners of the electroplating tank can be adjusted to achieve a stable placement of the electroplating tank.
[0041] Specifically, the tank body 1 is formed by integral injection molding, and the wall thickness of the tank body 1 is 20 mm. Flange interfaces 15 are also provided on both sides of the tank body 1. Two or more electroplating tanks can be connected through the flange interface 15. The ultrasonic transducer is located at the flange interface 15, and an ultrasonic transducer is provided at the flange interface, which can be controlled and driven by a controller to oscillate the electroplating liquid to form stirring, further ensuring the uniform temperature of the electroplating liquid, and at the same time ensuring the uniform concentration of the solution, thereby improving the quality of subsequent plating. The drain valve 14 is used to discharge the electroplating liquid used later. When the electroplating tank is cleaned later, the ultrasonic transducer can also be used to oscillate and clean the dirt attached to the inner wall of the electroplating tank to achieve rapid cleaning.
[0042] A method for induction treatment of condensed water in the electroplating tank described above is characterized by comprising the following steps:
[0043] 1) Use triangular tubes to form the outer facade of the notch profile, which is inclined to drain the condensed water downward;
[0044] 2) Use V-shaped or inverted V-shaped collecting troughs with inclined sidewalls to drain condensed water downward;
[0045] 3) Set up a V-shaped hole and let the condensed water flow through the hole. Connect the electrode rod to generate signal induction, which is then received by the controller. Ultrasonic vibration is used to accelerate the collection of condensed water, or to start the heating of the side wall, or to deal with the electroplating treatment of the environmental impact of the condensed water.
[0046] The above-mentioned method for sensing and treating condensed water can be realized intelligently and effectively, and can further intelligently assist the electroplating process.
[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
