Description

Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a zinc plating device with intelligent ion concentration control. Background Art

[0002] Electrogalvanizing is a metal anti-corrosion treatment method that uses electric current to reduce zinc ions to zinc metal and deposit it on the surface of the plated object. This process is an electrochemical reaction, usually accompanied by the release of heat.

[0003] At present, it is difficult to control the concentration of zinc ions during the electrogalvanizing process. When the concentration of zinc ions is low, the nucleation overpotential may increase during the electrodeposition process, which will affect the nucleation process of zinc on the cathode surface. At the same time, low concentrations of zinc ions may also cause uneven crystal growth, affecting the quality and appearance of the coating. When the concentration of zinc ions is high, unevenness may occur on the surface of the coating, such as the formation of protrusions or dendrites. These unevennesses will affect the appearance and performance of the coating and reduce the aesthetics and practicality of the product. Summary of the invention

DETAILED DESCRIPTION

[0077] At present, it is difficult to control the concentration of zinc ions during the electrogalvanizing process. When the concentration of zinc ions is low, the nucleation overpotential may increase during the electrodeposition process, which will affect the nucleation process of zinc on the cathode surface. At the same time, low concentrations of zinc ions may also cause uneven crystal growth, affecting the quality and appearance of the coating. When the concentration of zinc ions is high, unevenness may occur on the surface of the coating, such as the formation of protrusions or dendrites. These unevennesses will affect the appearance and performance of the coating and reduce the aesthetics and practicality of the product.

[0078] In view of this, if Figures 1 to 9 As shown, the present solution provides an ion concentration intelligent control galvanizing device, comprising a galvanizing pool 11 and a connection box 2 arranged on the upper part of a workbench 1;

[0079] The galvanizing tank 11 is fitted with the connection box 2;

[0080] The galvanizing pool 11 is provided with a plate 12, a workpiece to be galvanized and a zinc ion concentration detector 15;

[0081] The plate 12 is connected to the positive electrode;

[0082] The workpiece 13 to be galvanized is connected to the negative electrode.

[0083] Specifically, the galvanizing pool 11 is fitted with the connection box 2, and a plating solution is placed in the galvanizing pool 11. A pole plate 12 and a workpiece 13 to be galvanized are provided in the galvanizing pool 11. The pole plate 12 is connected to the positive electrode, and the workpiece 13 to be galvanized is connected to the negative electrode. Both the pole plate 12 and the workpiece 13 to be galvanized are immersed in the plating solution. A zinc ion concentration detector 15 is fixedly connected to the galvanizing pool 11 for detecting the zinc ion concentration of the plating solution.

[0084] like Figures 3 to 5 As shown, it also includes a first adjustment component;

[0085] The first adjustment assembly includes a motor 3 and a piston mechanism disposed in the connection box 2;

[0086] The piston mechanism includes a crank 33, a piston rod 36, a piston cylinder 39, a sealing plug 38 and a hinge ball 37;

[0087] The output end of the motor 3 is fixedly connected to the crank 33 via the rotating shaft 32;

[0088] One end of the crank 33 away from the rotating shaft 32 is fixedly connected to the piston rod 36 via a connecting rod 34;

[0089] A first collar 35 is also provided between the connecting rod 34 and the piston rod 36;

[0090] The piston rod 36 is plugged into the piston cylinder 39;

[0091] The sealing plug 38 is disposed between the piston rod 36 and the piston cylinder 39;

[0092] A hinge ball 37 is provided at one end of the piston rod 36 away from the connecting rod 34;

[0093] The hinge ball 37 is hinged to the sealing plug 38;

[0094] Two sets of piston mechanisms are arranged in the connection box 2;

[0095] The first rings 35 of the two sets of piston mechanisms are respectively fixedly connected to the connecting rods 34;

[0096] The two groups of piston cylinders 39 are connected to one end of the confluence pipe 4 through the first connecting pipe 41 and the second connecting pipe 42 respectively, and the other end of the confluence pipe 4 is connected to the galvanizing pool 11;

[0097] The first connecting pipe 41 and the second connecting pipe 42 are each provided with a one-way valve;

[0098] The one-way valve allows the galvanizing solution to flow only from the galvanizing tank 11 to the piston cylinder 39 .

[0099] Specifically, a motor frame 31 is fixedly connected in the connection box 2, and a motor 3 is fixedly connected to the motor frame 31. A rotating shaft 32 is fixedly connected to the output end of the motor 3, and a crank 33 is fixedly connected to the rotating shaft 32. A connecting rod 34 is fixedly connected to the end of the crank 33 away from the rotating shaft 32. A first sleeve 35 is sleeved on the connecting rod 34, and a piston rod 36 is fixedly connected to the first sleeve 35. A hinge ball 37 is fixedly connected to the piston rod 36. A piston cylinder 39 is fixedly connected in the connection box 2, and a sealing plug 38 is slidably connected in the piston cylinder 39. The sealing plug 38 is hinged to the hinge ball 37; therefore, after the motor 3 is started, the rotating shaft 32 drives the crank 33 to rotate, so that the connecting rod 34 rotates with the rotating shaft 32 as the center. The plug 38 is hinged, and the sealing plug 38 is limited by the piston cylinder 39, so that the sealing plug 38 can slide back and forth up and down in the piston cylinder 39. The purpose of setting the one-way valve is that when the sealing plug 38 slides upward, a negative pressure is generated in the piston cylinder 39, and the plating liquid in the galvanizing pool 11 is sucked into the piston cylinder 39 through the first connecting pipe 41. Then, when the sealing plug 38 slides downward, a positive pressure is generated in the piston cylinder 39, and the plating liquid in the piston cylinder 39 is discharged into the galvanizing pool 11 through the second connecting pipe 4, so that the plating liquid in the galvanizing pool 11 is circulated to keep the composition and temperature of the plating liquid in the galvanizing pool 11 uniform, while reducing the thickness of the electrode interface diffusion layer. At the same time, the circulation of the plating liquid also helps to evenly distribute the metal ions and avoid the occurrence of concentration polarization.

[0100] Preferably, the zinc ion concentration detector 15 is electrically connected to the first regulating component. When the zinc ion concentration detector 15 detects that the zinc ion concentration of the electroplating solution is low, the rotation rate of the motor 3 is accelerated, thereby accelerating the circulation rate, accelerating the replenishment and dissolution of zinc ions, and the rotation rate of the motor 3 is adapted to the zinc ion concentration detector 15, so that the rotation rate of the motor 3 can be controlled by the zinc ion concentration of the electroplating solution.

[0101] like Figure 2 , Figure 5 and Figure 6 As shown, it also includes a feeding component 5;

[0102] The feeding assembly 5 includes a feeding chamber 51 and a feeding rod 53;

[0103] The feeding chamber 51 is provided with a feeding port 52 at the top and an inclined surface at the bottom;

[0104] The feed port 14 of the galvanizing pool 11 is connected to the feeding port 52;

[0105] The feeding rod 53 is slidably connected to the feeding chamber 51 through the first sliding groove;

[0106] A first spring 55 is provided between the feeding rod 53 and the feeding chamber 51;

[0107] The feeding assembly 5 also includes a baffle 57 and a stop rod 58;

[0108] The baffle 57 is slidably connected to the feeding chamber 51 through the second chute;

[0109] A second spring 56 is provided between the baffle 57 and the feeding chamber 51;

[0110] The stop rod 58 is disposed on a side of the baffle plate 57 close to the feeding rod 53 .

[0111] Specifically, zinc salt is placed in the feeding chamber 51, the bottom surface of the feeding chamber 51 is an inclined surface, a feeding port 52 is provided on the feeding assembly 5, a feeding port 14 is provided on the galvanizing pool 11, the feeding port 52 is connected with the feeding port 14, the feeding port 52 and the feeding port 14 are both inclined, a first chute is provided on the feeding assembly 5 and a feeding rod 53 is slidably connected through the first chute, the top surface of the feeding rod 53 is also an inclined surface, the inclined surface of the feeding rod 53 is adapted to the inclined surface box of the bottom surface of the feeding chamber 51, a stop block 54 is fixedly connected to the feeding rod 53, and a first spring 55 is sleeved on the feeding rod 53 The two ends of the first spring 55 are fixedly connected to the stop block 54 and the feeding assembly 5 respectively, and the stop block 54 is abutted against the connecting rod 34, so that when the connecting rod 34 rotates with the rotating shaft 32 as the center, the feeding rod 53 is reciprocated up and down through the cooperation of the first spring 55, so that when the feeding rod 53 is in the reset state, the inclined surface of the feeding rod 53 and the inclined surface of the bottom surface of the feeding chamber 51 are located on the same inclined surface, so that the zinc salt in the feeding chamber 51 slides onto the inclined surface of the feeding rod 53, and then the feeding rod 53 slides upward, so that the feeding rod 53 passes through the inclined surface, and the feeding rod 53 The inner wall of the feeding chamber 51 is contacted, so that the feeding rod 53 drives the zinc salt on its inclined surface to slide upward until it reaches the sliding feeding port 52, and then the zinc salt on the inclined surface is fed into the galvanizing pool 11 through the feeding port 52 to replenish zinc ions; at the same time, because the rotation speed of the connecting rod 34 is synchronously accelerated when the zinc ion concentration detector 15 detects that the zinc ion concentration of the electroplating solution is low, the sliding speed of the feeding rod 53 is synchronously accelerated, thereby increasing the amount of zinc salt fed, so that the amount of zinc salt fed can be controlled according to the zinc ion concentration of the plating solution; a second chute is provided on the feeding assembly 5, and through The second slide groove is slidably connected with a baffle 57, and a second spring 56 is fixedly connected to the baffle 57. One end of the second spring 56 away from the baffle 57 is fixedly connected to the feeding assembly 5, and a push rod 58 is fixedly connected to the baffle 57. The push rod 58 is adapted to the feeding rod 53. When the baffle 57 is in the reset state, the baffle 57 blocks and seals the feeding port 52. When the feeding rod 53 slides upward, the high end of the inclined surface of the feeding rod 53 first contacts the push rod 58, thereby overcoming the elastic force of the second spring 56, and the baffle 57 slides upward, so that the baffle 57 cancels the blocking of the feeding port 52.

[0112] like Figures 7 to 9 As shown, it also includes a material receiving assembly;

[0113] The material receiving assembly includes a receiving box 6 and a liquid receiving bucket 67 arranged in the connection box 2;

[0114] The receiving box 6 is connected to the galvanizing pool 11 through the third connecting pipe 61;

[0115] The liquid receiving bucket 67 is arranged at the lower part of the receiving box 6;

[0116] A drain pipe 66 is provided on the upper portion of the receiving box 6;

[0117] One end of the liquid discharge pipe 66 is directly connected to the upper part of the liquid barrel 67, and the other end is connected to the middle part of the confluence pipe 4;

[0118] The side wall of the liquid receiving barrel 67 is provided with a liquid discharge port 68;

[0119] The inner diameter of the drain port 68 is smaller than the inner diameter of the drain pipe 66 .

[0120] Specifically, when the zinc ion concentration of the electroplating solution is low, the rate at which the piston cylinder 39 absorbs and discharges water is accelerated. Since the inner diameter of the discharge port 68 of the liquid receiving barrel 67 is smaller than the inner diameter of the discharge pipe 66, more and more water is accumulated in the liquid receiving barrel 67, and the amount of electroplating solution in the galvanizing pool 11 is reduced accordingly. Therefore, after the zinc salt is added, the zinc ion content in the galvanizing pool 11 is rapidly increased.

[0121] Preferably, it further includes a second adjustment component;

[0122] The second adjustment assembly includes a support rod 69, a counterweight 64, a second ring 62 and a sliding resistor 7;

[0123] The support rod 69 is arranged in the receiving box 6;

[0124] The second ring 62 is rotatably connected to the support rod 69;

[0125] The second ring 62 is fixedly connected to the liquid receiving bucket 67 via a drawstring 65;

[0126] The counterweight block 64 is fixedly connected to the second ring 62 via a fixing rod 63;

[0127] The counterweight block 64 is fixedly connected to the sliding rod 73 of the sliding rheostat 7 via the ball 74;

[0128] The positive electrode of the sliding rheostat 7 is connected to the electrode plate 12;

[0129] The negative pole of the sliding resistor 7 is connected to the workpiece 13 to be galvanized.

[0130] Specifically, a support block 71 is fixedly connected in the connection box 2, and a sliding rheostat 7 and a connecting plate 72 are fixedly connected to the support block 71. A sliding groove is provided on the connecting plate 72, and a sliding rod 73 is slidably connected to the sliding groove. The sliding rod 73 is fixedly connected to the sliding plate 76 of the sliding rheostat 7, and the end of the sliding rod 73 away from the sliding plate 76 is fixedly connected to the ball 74, and the ball 74 abuts against the counterweight 64. A third spring 75 is sleeved on the sliding rod 73, and the two ends of the third spring 75 are respectively fixedly connected to the connecting plate 72 and the sliding plate 76. As the weight increases, the weight of the liquid receiving bucket 67 gradually increases until it overcomes the gravity of the counterweight 64, causing the fixed rod 63 to rotate with the support rod 69 as the center, thereby causing the counterweight 64 to rotate synchronously. Since the ball 74 abuts against the counterweight 64, the ball 74 drives the sliding rod 73 to slide toward the end away from the receiving box 6, thereby reducing the resistance of the sliding rheostat 7. Since the sliding rheostat 7 is electrically connected to the positive and negative electrodes, the power supply to the positive and negative electrodes is increased to accelerate the reduction rate of zinc ions, thereby allowing the current to be adjusted by the zinc ion concentration.

[0131] This solution has at least the following beneficial effects:

[0132] 1. By fixedly connecting the zinc ion concentration detector in the galvanizing pool, the concentration of zinc ions in the plating solution can be monitored in real time. When the zinc ion concentration is detected to be low, the circulation rate of the plating solution can be accelerated by adjusting the rotation speed of the motor, thereby accelerating the replenishment and dissolution of zinc ions to maintain a suitable concentration of the plating solution.

[0133] 2. Through the design of the piston cylinder and the connecting rod, the piston cylinder slides up and down reciprocatingly after the motor is started to realize the circulation of the plating solution, thereby maintaining the uniform composition and temperature of the plating solution, reducing the thickness of the electrode interface diffusion layer, and avoiding the occurrence of concentration polarization.

[0134] 3. A feeding component is added, which can adjust the amount of zinc salt added according to the change of zinc ion concentration, thereby controlling the zinc ion content in the plating solution.

[0135] 4. Through the design of the second regulating component, the current can be adjusted according to the increase of liquid in the receiving barrel to accelerate the reduction rate of zinc ions and effectively remove metal impurities in the plating solution.

[0136] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
