Description

Technical Field

[0001] The invention relates to the field of electroplating, and in particular to an electroplating tank. Background Art

[0002] Electroplating is to use the principle of electrolysis to plate a thin layer of metal on the surface of the workpiece. The temperature control of the liquid in the electroplating tank directly affects the monitoring of the instrument and equipment due to its temperature change parameters, which affects the quality of electroplating. It is often necessary to monitor the parameters every 2h or 1h so that they can be adjusted to the standard value in time to make the electroplating stable. Different plating materials and additives determine different temperature requirements for the electroplating solution. For example, when plating bright nickel, the temperature of the electroplating solution needs to be maintained between 55-65℃, while the temperature of silver plating is around 10℃. During electroplating, the equipment is generally used to directly heat the electroplating solution, and the temperature matching of the electroplating tank itself is often ignored. The electroplating tank is generally a plastic body, and the electroplating tank does not have self-heating. When the liquid is just heated, the temperature of the electroplating solution at the slot is inconsistent with that at the bottom of the tank, forming a large temperature difference, which in turn causes uneven electroplating quality in the bottom and slot areas. If the temperature of the electroplating solution reaches the upper or lower critical limit, the control of the temperature of the slot and the bottom of the tank is the key to the 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 meets 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 on the market currently adopt an outward-turned structure design for the notch, and condensed water will accumulate at the notch. During long-term production, condensed water will enter the electroplating tank from the notch, 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

[0016] 1) The outer surface of the notch profile formed by using a triangular tube is inclined to drain the condensed water from the notch downward;

[0017] 2) Use V-shaped or inverted V-shaped collecting tank side walls with inclined design to drain condensed water downward;

[0018] 3) Set up a V-shaped hole and let the condensed water flow through the hole, connect the electrode rod to generate signal induction, and then receive it through the controller to perform ultrasonic vibration on the tank body to accelerate the collection of condensed water, or start the heating side wall treatment, or deal with the electroplating treatment caused by the environmental impact of the condensed water.

[0019] The present invention has the beneficial effects:

[0020] 1. The profile 1 is set at the slot to connect the structure of the transfer block and the profile 2 at the bottom of the tank body. The cross-sectional profile of the profile 1 is a triangular tube, and it is made of aluminum alloy, has good rigidity, and has a built-in heating film, forming a stable reinforcement structure that is both detachable at the mouth and the bottom. The built-in heating film can be controlled by the controller to heat the slot and the bottom of the tank to solve the problem of constant temperature of the slot and the bottom of the tank during electroplating, which can realize the self-heating of the device body and the auxiliary function of the plating liquid, so that the plating liquid at the slot and the bottom of the tank is kept at the same temperature, avoiding a large temperature difference between the plating liquid at the bottom and the slot, 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 heating of the trough structure, the condensed water on the end face of the notch can 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 condensed water from entering the tank to affect the concentration of the plating solution and the introduction of new impurities.

In addition, ultrasonic vibration can be used to clean impurities attached to the inner wall of the plating tank, reducing the difficulty of later cleaning.

[0022] 2. Reinforcement ribs 1 and 2 are arranged on the trough body, which not only strengthen the overall structure of the trough body, but also play a drainage effect, draining the condensed water on the outer side of the trough body into the water receiving tray for collection, so as to avoid the trough body or ground moisture caused by the condensed water, or affect the accurate use of other electronic equipment.

DETAILED DESCRIPTION

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0032] Please refer to Figure 1 , 2 3. An electroplating tank comprises a tank body 1 and a notch at the top, wherein the tank body 1 is provided with a condensation water induction processing mechanism and a constant temperature mechanism, wherein the constant temperature mechanism comprises a profile 2 and a profile 3, wherein a ring-shaped groove 16 is arranged on the periphery of the notch, wherein the length of the profile 2 matches the length and width of the notch, wherein two adjacent profiles 2 are connected via an adapter 4, wherein the adapter 4 is provided with two plugs 41, wherein the plugs 41 match and plug into the pipe mouths of the profile 2, wherein threaded holes are arranged on the plugs 41, wherein threaded holes at corresponding positions are arranged at the pipe mouths of the profile 2, wherein the plugs 41 are inserted into the profile 2 and fixed by screws to realize connection and fixation of adjacent profiles, wherein one side of the profile 2 is embedded and fixed in the groove 16, and then connected via the adapter 4, wherein the profile 2 is spliced ​​into a rectangular frame and fixed in the groove 16 on the notch, and wherein the profile 2 is detachably installed at the notch, which is convenient for replacement and maintenance, and at the same time increases the structural stability of the notch and avoids deformation of the notch.

[0033] The slot is set, 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 detachable reinforcement structure of the mouth, and the built-in heating film can be controlled by a controller to heat the slot to solve the problem of constant temperature of the slot during electroplating, and realize that the plating liquid at the slot maintains the same temperature, avoids large temperature differences in the plating liquid at the slot, and ensures 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 realizing 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 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 generation, and is controllable, and very flexible to use.

[0034] 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. The strength of the notch and the bottom of the trough is reinforced. 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 film on the inner wall of the tube. The heating film adopts graphene heating film. The graphene heating film has 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, thereby 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.

[0035] The electroplating tank is also provided with an ultrasonic transducer (not shown in the figure, the ultrasonic transducer is a prior art and will not be described one by one here). While heating, the ultrasonic transducer can be started to radiate ultrasonic waves into the plating solution through the wall of the electroplating 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.

[0036] Please refer to Figure 2 , 3 4. The condensed 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 reinforcing ribs 11 and 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. Two electrode rods 7 are arranged outside the small hole and fixed on the reinforcing rib 11. The two electrode rods 7 are connected to a current sensor 71. 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. 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 ribs 11 and 12. When the condensed water flows through the bottom of the reinforcing rib 11, the two electrode rods 7 are connected 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 to accelerate 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, or making fine adjustments to the electroplating parameters. At the same time, it avoids long-term moisture on the equipment and the ground, which affects the operation of the equipment, improves production safety, and achieves reinforcement, drainage, sensing of condensed water, and electroplating treatment response to the condensed water environment with a simple structure.

[0037] During early warning processing, the bottom of the reinforcing rib 11 is respectively provided with an electrode rod and a current sensor, so as to form a separate detection and sensing of the condensed water conditions around the electroplating tank, and different sensing early warning processing controls can be performed on the four sides to further achieve precise control. For example, when only one side generates a signal, it means that the electrical instrument or temperature at this side needs to be slightly adjusted, while the electrical instruments or temperatures at other sides do not need to be adjusted.

[0038] 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 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 V-shaped reinforcement rib 1 and 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, thereby further ensuring the temperature environment of the groove surface and also ensuring the quality of electroplating.

[0039] 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 condensed water spilling. Adjustable supporting feet 6 are provided under the four corners of the tray 5, and a gasket 61 is further provided between the adjustable supporting feet 6 and the tray 5. The adjustable supporting feet 6 are connected to the tray 5 through threads. The height of the four corners of the electroplating tank can be adjusted by adjusting the supporting feet 6 to achieve a stable placement of the electroplating tank.

[0040] 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 driven by a controller to oscillate the electroplating liquid to form stirring, further ensuring the uniform temperature of the electroplating liquid, while ensuring the uniform concentration of the solution, and improving the quality of subsequent plating. The drain valve 14 is used to discharge the electroplating liquid used up 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.

[0041] A method for inductively treating condensed water in the electroplating tank described above, characterized in that it comprises the following steps:

[0042] 1) The outer surface of the notch profile formed by using a triangular tube is inclined to drain the condensed water from the notch downward;

[0043] 2) Use V-shaped or inverted V-shaped collecting tank side walls with inclined design to drain condensed water downward;

[0044] 3) Set up a V-shaped hole and let the condensed water flow through the hole, connect the electrode rod to generate signal induction, and then receive it through the controller to perform ultrasonic vibration on the tank body to accelerate the collection of condensed water, or start the heating side wall treatment, or deal with the electroplating treatment caused by the environmental impact of the condensed water.

[0045] The above-mentioned method for sensing and processing condensed water can be realized completely intelligently and effectively, and can further intelligently assist the electroplating process.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
