[0002] The electroplating tank is one of the indispensable equipment in the electroplating industry. It is mainly used to store the electroplating solution and load the workpiece for electrolytic plating during the electroplating process.
[0003] The electroplating tank is mainly composed of a tank body, a conductive device, a heating and cooling system, etc. Its working principle is to immerse the metal workpiece in a solution containing metal ions, connect the positive and negative poles of a DC power supply, so that the metal ions are reduced to metal atoms in the electrolyte and deposited on the surface of the workpiece to form a uniform and dense metal coating.
[0004] The existing electroplating tank cannot evenly replenish the electroplating liquid, resulting in uneven thickness of the electroplating layer on the surface of the workpiece, which will cause significant differences in the electroplating effects of different parts of the workpiece, affecting the electroplating effect and reducing the electroplating quality. Therefore, in order to solve the above problem, an electroplating tank with uniform jet plating liquid is proposed. Utility Model Content

A spring is fixed between the tops of the cylinders, a movable electrode plate is fixed to the top of the limiting cap, a movable electrode ring is fixed to the bottom of the limiting cap, a fixed electrode plate is installed on the top inner wall of the fixing frame, a fixed electrode ring is fixed to the top of the sleeve, and the movable electrode ring and the fixed electrode ring are both arranged around the movable rod, a first indicator light and a second indicator light are respectively installed on the side walls of the fixing frame, and the first indicator light, the movable electrode plate and the fixed electrode plate are electrically connected, and the second indicator light, the movable electrode ring and the fixed electrode ring are electrically connected, a storage battery is installed on the side wall of the fixing plate, and during the rehydration process When the liquid pressure is too high, the high-pressure gas in the infusion tube will push the piston upward, and then the movable rod will drive the movable electrode plate to move up to contact with the fixed electrode plate. The first indicator light will be powered on and light up, so as to promptly remind the operator that the pressure in the infusion tube is too high and pressure reduction is required. Through the operation of the hydraulic cylinder, the hydraulic rod will drive the liquid storage cylinder to move vertically downward, thereby shortening the distance between the liquid storage cylinder and the infusion tube, that is, the depth of the liquid from the surface becomes smaller, so that the pressure in the infusion tube can be reduced. When the liquid pressure is too low, the piston in the sleeve will move downward, so that the movable rod will drive the movable electrode ring to move downward to contact with the fixed electrode ring. The second indicator light will turn on and light up, so as to promptly remind the operator that the pressure in the infusion tube is too high and pressure reduction is required. The light becomes brighter when powered on, which can promptly remind the operator that the pressure in the refilling tube is too low and the pressure in the refilling tube needs to be increased. The hydraulic cylinder operates to make the hydraulic rod drive the liquid storage cylinder to move up and down vertically, thereby increasing the distance between the liquid storage cylinder and the refilling tube, that is, the depth of the liquid from the surface becomes greater, thereby increasing the pressure in the refilling tube. Through this structural design, the pressure in the refilling tube can be controlled to keep it within an appropriate pressure range, avoiding the phenomenon of excessive or insufficient pressure in the refilling tube, so that the electroplating tank can be evenly refilled, making the thickness of the electroplating layer on the surface of the workpiece uniform, improving the electroplating effect, and also improving the electroplating quality.

[0008] Preferably, a U-shaped frame is fixedly connected to the port of the refilling tube, an outer spray hole is opened on the U-shaped frame, a sealing plate is arranged in the U-shaped frame, an inner spray hole is opened on the sealing plate, and the outer spray hole has the same diameter as the inner spray hole, a float rod is fixedly connected to the bottom end of the sealing plate, a float ball is fixedly connected to the bottom end of the float rod, a lifting rod is fixedly connected to the top end of the sealing plate, and an anti-drop cap is fixedly connected to the top end of the lifting rod through the top of the U-shaped frame. During the refilling process, as the refilling proceeds, when the liquid in the electroplating tank gradually increases, when the liquid reaches a certain amount, the float ball will push the float rod to move upward, so that the sealing plate moves upward, and the inner spray hole also moves upward accordingly, and the inner spray hole is away from the outer spray hole. The sealing plate blocks the outer spray hole, thereby stopping the refilling and avoiding overflow due to excessive liquid in the electroplating tank.
[0009] The utility model is beneficial in that:
[0010] 1. In the process of rehydration, when the liquid pressure is too high, the high-pressure gas in the rehydration tube will push the piston upward, and then the movable rod drives the movable electrode plate to move up to contact the fixed electrode plate, and the first indicator light turns on, so as to timely remind the operator that the pressure in the rehydration tube is too high and needs to be reduced. Through the operation of the hydraulic cylinder, the hydraulic rod drives the liquid storage cylinder to move vertically downward, thereby shortening the distance between the liquid storage cylinder and the rehydration tube, that is, the depth of the liquid from the surface becomes smaller, so that the pressure in the rehydration tube can be reduced;

Through the operation of the hydraulic cylinder, the hydraulic rod drives the liquid storage cylinder to move up and down vertically, thereby increasing the distance between the liquid storage cylinder and the rehydration tube, that is, the depth of the liquid from the surface becomes larger, thereby increasing the pressure in the rehydration tube;
[0012] 3. The utility model controls the pressure in the refilling tube so that it can be maintained within an appropriate pressure range, thereby avoiding the phenomenon of excessive or insufficient pressure in the refilling tube, thereby evenly refilling the electroplating tank and making the thickness of the electroplating layer on the surface of the workpiece uniform, thereby improving the electroplating effect and also improving the electroplating quality.

Through this structural design, the pressure in the infusion tube 3 can be controlled to keep it within a suitable pressure range, avoiding the phenomenon of excessive or insufficient pressure in the infusion tube 3, thereby evenly replenishing the electroplating tank, making the thickness of the electroplating layer on the surface of the workpiece uniform, improving the electroplating effect, and also improving the electroplating quality;
[0026] During the refilling process, as the refilling proceeds, the liquid in the electroplating tank gradually increases. When the liquid reaches a certain amount, the float 29 will push the float rod 28 upward, causing the sealing plate 26 to move upward, and the inner jet hole 27 to move upward accordingly.
