Description

Technical Field

[0001] The present invention relates to the technical field of electroplating treatment on the surface of welding wires, and specifically to an electroplating treatment device for welding wires. Background Art

[0002] Electroplating is a process of plating a layer of metal or alloy on the surface of an object through the principle of electrolysis, which is widely used in industrial manufacturing, decoration, electronics and other fields. A welding wire is a metal wire used to fill a weld seam and conduct current during the welding process. In order to prevent oxidation on the surface of the welding wire and improve the contact efficiency between the welding wire and the contact tip, it is often necessary to coat the surface of the welding wire. Usually, this coating is carried out through electroplating treatment. A patent of invention with the Chinese patent publication number CN117867625B discloses an electroplating treatment device, including an electroplating tank, an electroplating solution reagent storage tank, a liquid concentration detector, a dosing metering pump and a bracket. The electroplating tank is used to hold the electroplating solution and the product to be electroplated; the electroplating solution reagent storage tank is used to store electroplating solution reagents, and the electroplating solution reagent storage tank and the electroplating tank are connected through a dosing pipe; the dosing metering pump is arranged on the dosing pipe, and the dosing metering pump is electrically connected to the liquid concentration detector, which has the advantages of reducing the cost of electroplating equipment and electroplating solution and effectively improving the efficiency of treating electroplating solution and electroplating products.

[0003] In the prior art, during the continuous electroplating process of welding wires, usually a pay-off and take-up reel is used to feed the welding wire into the electroplating tank from one side, electroplate it, and then lead it out from the other side of the electroplating tank. By applying electricity to the anode plates fixedly arranged on the inner walls of both sides of the electroplating tank and the welding wire, a circuit is formed through the electrolyte for reaction. The following problems exist in this process: 1. The fixedly arranged anode plates result in different electrode distances between the upper and lower surfaces and the left and right surfaces of the passing welding wire, resulting in different current densities, and further causing the thickness of the coating to be not uniform enough; 2. Cleaning mechanisms need to be arranged on the surfaces of the welding wire before and after electroplating respectively to clean impurities such as dust on the surface of the welding wire before electroplating and wipe and clean the residual electrolyte on the surface of the welding wire after electroplating, which is not convenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an electroplating treatment device for welding wires to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: A wire electroplating treatment device, including an electroplating tank, a lifting mechanism is installed on the top side of the electroplating tank, a wire threading mechanism for allowing the wire to enter and exit the electroplating tank on the same side is installed on the lifting mechanism, a rotating mechanism for rotating the anode in the plating tank is installed on the wire threading mechanism, a cleaning mechanism for simultaneously scraping and cleaning the wire entering and exiting the electroplating tank is installed on the rotating mechanism, a contact mechanism for pressing the anode is installed on the cleaning mechanism, a conductive mechanism for simultaneously energizing the wire at one end entering the electroplating tank and the contact mechanism is installed on the electroplating tank. During the continuous electroplating process of the wire, the wire is released from the unwinding reel by the pay-off and take-up reel, electroplated in the electroplating tank, and then wound by the take-up reel. This is common knowledge for those skilled in the art and will not be elaborated here. After one end of the wire is released from the unwinding reel, the bottom side of the wire threading mechanism is lifted to the top of the electroplating tank by the lifting mechanism, which facilitates threading the wire through the top of the wire threading mechanism, winding around the bottom side of the wire threading mechanism, and then exiting from the top of the wire threading mechanism on the same side. The exiting wire is pulled to the take-up reel and fixed. After the installation of the wire is completed, the lifting mechanism is reset to start the continuous electroplating process. At this time, the negative electrode of the conductive mechanism is electrically connected to the front end of the wire entering the electroplating tank, and the positive electrode of the conductive mechanism is electrically connected to the contact mechanism. The contact mechanism is in contact with the rotating mechanism. Thus, during the electroplating process, the anode rotates through the rotation of the rotating mechanism, thereby achieving a dynamic balance of the electrode distance and avoiding the phenomenon of uneven coating thickness caused by uneven electrode distance due to the fixed position of the anode. At the same time, the rotation of the anode can disturb the plating solution, accelerate the diffusion and convection of the plating layer ions. In addition, the rotation of the anode can reduce the accumulation of the passivation film on the anode surface, maintain the activity of the anode, and maintain a stable electrode reaction. The movement of the rotating mechanism drives the movement of the cleaning mechanism. The movement of the cleaning mechanism can wipe the dust and other impurities attached to the surface of the wire before electroplating and dry the residual plating solution on the surface of the wire after electroplating, improving the convenience and practicality of the structure.

[0006] The wire threading mechanism includes two rings. Connecting columns are installed on the side where the two rings are close to each other. Placing frames are installed on the sides where the two rings are far from each other. A fixed pulley is rotatably installed on the placing frame of the bottom ring. The fixed pulley is located on the central axis of the ring. A bridge is installed on the placing frame of the top ring. A pulley group is rotatably installed on the bridge. The wire enters the electroplating tank through one of the pulleys of the pulley group, winds around the fixed pulley for half a turn, and then exits through the other pulley. It should be noted that the wires on both sides of the fixed pulley are arranged parallel to the central axis of the ring. Thus, during the continuous electroplating process of the wire, the travel of the wire in the electroplating tank is increased, thereby increasing the electroplating time of the wire, which is beneficial to more uniform electroplating. And it makes the distance from the anode to each part of the surface of the unit cross-sectional circle of the wire equal during the total travel in the electroplating tank, which is further beneficial to uniform electroplating.

[0007] Furthermore, the rotating mechanism includes a rotating ring rotatably mounted on the top-side circular ring. An insulating sleeve is mounted on the rotating ring, and an anode plate is movably mounted inside the insulating sleeve. Continuous teeth are provided on the rotating ring, and a rotating seat is mounted on the top-side circular ring. A stepping motor is mounted on one side of the rotating seat. The main shaft of the stepping motor is rotatably mounted on the rotating seat and penetrates to the other side of the rotating seat. A transmission gear is mounted on the main shaft of the stepping motor, and the transmission gear meshes with the continuous teeth. When the stepping motor is started, the stepping motor drives the transmission gear to rotate. The rotation of the transmission gear restricts the rotation of the rotating ring on the circular ring through meshing with the continuous teeth. The rotation of the rotating ring drives the anode plate inside the insulating sleeve to rotate simultaneously, thus realizing the rotation of the anode plate. It should be noted that by placing the anode plate inside the insulating sleeve, the excessive dissolution at the edge caused by the strong electric field at the edge of the anode plate is reduced, which is beneficial to the uniformity of the electroplating coating.

[0008] Furthermore, a sealing frame strip is mounted on the insulating sleeve. The sealing frame strip is made of rubber material. Through the setting of the sealing frame strip, the contact risk between the electroplating solution and the edge of the anode plate is reduced.

[0009] Furthermore, limiting ribs are mounted on the rotating ring, and limiting rotating grooves are formed on the top-side circular ring. The limiting ribs are rotatably mounted in the limiting rotating grooves. The limiting ribs restrict the movement of the rotating ring. With the restriction of the limiting rotating grooves, the rotating ring can only rotate on the top-side circular ring.

[0010] Furthermore, the cleaning mechanism includes an annular frame mounted on the insulating sleeve. Connecting rods are mounted on the annular frame, and a transmission sleeve is mounted on the connecting rods. A collecting circular frame is slidably mounted inside the transmission sleeve. A limiting sliding rod is slidably mounted on the collecting circular frame, and the limiting sliding rod is mounted on the placing frame of the top-side circular ring. A partition is mounted on the collecting circular frame. Connecting shafts are mounted on both side walls of the partition. A brush sleeve is mounted on one of the connecting shafts, and a cotton cloth sleeve is mounted on the other connecting shaft. When the insulating sleeve rotates, it drives the annular frame to rotate. When the annular frame rotates, it drives the connecting rods and the transmission sleeve to rotate. When the transmission sleeve rotates, it drives the collecting circular frame to slide back and forth inside the transmission sleeve. When the collecting circular frame slides back and forth, it drives the connecting shafts on both sides of the partition to slide back and forth. Thus, the brush sleeve on one side slides back and forth and scrapes the surface of the welding wire before it enters the electroplating tank, preventing dust and other impurities from entering the electroplating tank. At this time, the cotton cloth sleeve on the other side dries the residual electroplating solution on the surface of the welding wire that has passed through, preventing the residual electroplating solution from conducting electricity and continuing to participate in the reaction.

[0011] Furthermore, a transmission shaft block is mounted on the collecting circular frame, and an elliptical sliding groove is formed on the transmission sleeve. The transmission shaft block is slidably mounted in the elliptical sliding groove. Through the setting of the elliptical sliding groove, when the transmission sleeve rotates, it drives the transmission shaft block to slide in the elliptical sliding groove. Under the limiting action of the limiting sliding rod, the collecting circular frame slides back and forth inside the transmission sleeve.

[0012] Further, the contact mechanism includes a conductive ring, which is installed in the installation groove formed on the annular frame. A conductive screw is threadedly installed on the conductive ring. A through hole is formed on the insulating sleeve, and the conductive screw is slidably installed in the through hole. The conductive screw contacts the anode plate. When the anode plate is placed in the insulating sleeve, as the conductive screw rotates on the conductive ring and approaches and presses the anode plate, it is realized that when the current flows through the conductive ring, the current is conducted to the anode plate through the contact between the conductive screw and the anode plate. It should be noted that the hexagonal turning block part at the rear end of the conductive screw is non-conductive.

[0013] Further, the conductive mechanism includes a fixed frame, which is installed on the electroplating tank. An arched frame is installed on the fixed frame. A connecting plate is installed on the ring on the top side. A limiting groove is formed on the annular frame, and the connecting plate is slidably installed in the limiting groove. Conductive sliding columns are slidably installed on both the connecting plate and the arched frame. Conductive brushes are installed on both of the two conductive sliding columns. Springs are sleeved on both of the two conductive sliding columns. Wires are electrically connected to both of the two conductive sliding columns. A power supply is installed on the fixed frame. The positive terminal of the power supply is electrically connected to the wire on the connecting plate, and the negative terminal of the power supply is electrically connected to the wire on the arched frame. When the power supply is started, the current of the power supply flows out from the positive terminal and is transmitted to the conductive sliding column and the conductive brush on the connecting plate through the wire, then is transmitted to the conductive screw through the conductive ring, and finally enters the electrolyte in the electroplating tank through the anode plate and reaches the conductive sliding column on the arched frame through the welding wire, and then reaches the negative terminal of the power supply through the wire. Through the setting of the spring, the electrical connection stability during the movement of the welding wire and the conductive ring is increased, and the practicability of the structure is further improved. It should be noted that the contact parts of the conductive sliding column and the conductive brush with the spring are coated with insulating paint and are non-conductive.

[0014] Further, the lifting mechanism includes a sliding frame, which is installed on the electroplating tank. A threaded rod is rotatably installed on the sliding frame. A connecting seat is threadedly installed on the threaded rod. The ring is installed on the connecting seat. A threaded hole is formed on the connecting seat, and the threaded rod is threadedly installed in the threaded hole. When the threaded rod rotates, it drives the connecting seat to slide up or down on the sliding frame.

[0015] Further, a motor is installed on the sliding frame, and the main shaft of the motor is installed on the threaded rod. Through the setting of the motor, it is realized that when the motor is started, it drives the threaded rod to rotate, and the automation degree of the structure is improved.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, through the settings of a pulley block, a fixed pulley, a rotating ring, a collecting circular frame, etc., during the continuous electroplating process of the welding wire, by the way of the welding wire passing in and out on one side of the electroplating tank and cooperating with the rotation of the anode plate, the dynamic balance of the electrode distance is achieved, the travel of the welding wire in the electroplating tank is extended, the coating uniformity is improved, and the rotation of the anode plate drives the collecting circular frame to slide reciprocally while scraping the surfaces of the welding wire before and after electroplating, improving the use convenience of the structure.

[0017] In the present invention, through the settings of a conductive circular ring, a conductive screw rod, etc., while increasing the installation stability of the anode plate by pressing the anode plate, the conductive intercommunication between the conductive circular ring and the anode plate is realized, further improving the practicality and use convenience of the structure. The settings of insulating sleeves, etc., reduce the excessive dissolution at the edge caused by the strong electric field at the edge of the anode plate, which is beneficial to the uniformity of the electroplating coating.

[0018] In the present invention, through the settings of insulating sleeves, etc., the excessive dissolution at the edge caused by the strong electric field at the edge of the anode plate is reduced, which is beneficial to the uniformity of the electroplating coating.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-8, A wire electroplating treatment device in the illustration includes an electroplating tank 1. A lifting mechanism 2 is installed on the top side of the electroplating tank 1. A wire threading mechanism 3 for allowing the wire to enter and exit the electroplating tank 1 on the same side is installed on the lifting mechanism 2. A rotating mechanism 4 for rotating the anode in the plating tank is installed on the wire threading mechanism 3. A cleaning mechanism 5 for simultaneously scraping and cleaning the wire entering and exiting the electroplating tank 1 is installed on the rotating mechanism 4. A contact mechanism 6 for pressing the anode is installed on the cleaning mechanism 5. A conductive mechanism 7 for simultaneously energizing the wire entering one end of the electroplating tank 1 and the contact mechanism 6 is installed on the electroplating tank 1. During the continuous electroplating process of the wire, the wire is released from the unwinding reel by the pay-off and take-up reel, electroplated in the electroplating tank 1, and then wound by the take-up reel. This is common knowledge for those skilled in the art and will not be elaborated here. After one end of the wire is released from the unwinding reel, the bottom side of the wire threading mechanism 3 is lifted to the top of the electroplating tank 1 by the lifting mechanism 2, facilitating the wire to pass through the top of the wire threading mechanism 3, wind around the bottom side of the wire threading mechanism 3, and then exit from the top of the wire threading mechanism 3 on the same side. The exiting wire is pulled to the take-up reel and fixed. After the installation of the wire is completed, the lifting mechanism 2 is reset to start the continuous electroplating process. At this time, the negative electrode of the conductive mechanism 7 is electrically connected to the front end of the wire entering the electroplating tank 1, and the positive electrode of the conductive mechanism 7 is electrically connected to the contact mechanism 6. The contact mechanism 6 is in contact with the rotating mechanism 4. Thus, during the electroplating process, the rotation of the rotating mechanism 4 causes the anode to rotate, achieving a dynamic balance of the electrode distance and avoiding the phenomenon of uneven coating thickness caused by uneven electrode distance due to the fixed position of the anode. At the same time, the rotation of the anode can disturb the plating solution, accelerating the diffusion and convection of the coating ions. In addition, the rotation of the anode can reduce the accumulation of the passivation film on the anode surface, maintain the activity of the anode, and maintain a stable electrode reaction. The movement of the rotating mechanism 4 drives the movement of the cleaning mechanism 5. The movement of the cleaning mechanism 5 can wipe the dust and other impurities attached to the surface of the wire before electroplating and dry the residual plating solution on the surface of the wire after electroplating, improving the convenience and practicality of the structure.

[0024] The wire threading mechanism 3 includes two rings 301. Connecting columns 302 are installed on the side where the two rings 301 are close to each other.

A pulley block 306 is rotatably installed on the bridge 305. After the wire enters the electroplating tank 1 through one of the pulleys of the pulley block 306, it winds around the fixed pulley 304 for half a week and then winds out through the other pulley. It should be noted that the welding wires on both sides of the fixed pulley 304 are arranged parallel to the central axis of the circular ring 301, so that during the continuous electroplating process of the welding wire, the travel of the welding wire in the electroplating tank 1 is increased, thereby increasing the electroplating time of the welding wire, which is beneficial to more uniform electroplating, and making the anode distances of all parts of the surface of the unit cross-sectional circle of the welding wire equal during the total travel in the electroplating tank 1, which is further beneficial to uniform electroplating.
