Description

Technical Field

[0001] The utility model relates to the technical field of electroplating tanks, and more specifically, to an electroplating tank with uniform electroplating. Background Art

[0002] Electroplating is an important surface treatment process. It is based on the principle of electrolysis. Through a specific electrochemical process, a layer of metal or alloy film is deposited on the surface of metal or non-metallic materials. This film can not only enhance the performance of the substrate, such as preventing metal oxidation (rust), improving wear resistance, conductivity, reflectivity and corrosion resistance (such as resisting corrosive media such as copper sulfate), but also significantly improve the appearance of the object and increase its beauty. In many fields such as coin manufacturing, auto parts, hardware tools, and electronic products, electroplating technology plays an indispensable role. However, in the electroplating process, the uniformity of the plating solution has a decisive influence on the electroplating effect. In the electroplating tank of the prior art, metal parts are often in a static state, which makes it difficult for the plating solution to form a uniform covering layer on the surface of the metal parts. The uneven distribution of the plating solution will lead to a series of problems. First, some parts of the metal parts may be over-plated due to the excessively high concentration of the plating solution, which not only wastes the plating materials, but also may affect the performance and service life of the product.

[0003] Secondly, some other parts of the metal parts may be under-plated due to insufficient concentration of the plating solution, resulting in a decrease in the protective performance of the product or even failure to achieve the expected plating effect. In addition, the unevenness of the plating solution will also affect the quality of the electroplating layer. Since different areas on the surface of the metal parts are affected by different plating solutions, the electroplating layers formed may differ in thickness, structure and performance. Such differences will not only affect the overall performance of the product, but may also cause local damage or failure of the product during use. Therefore, it needs to be improved and optimized.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6 As shown, the utility model provides an electroplating tank with uniform electroplating, including a placement box 1, four moving wheels 2 are rotatably installed on the top of the placement box 1, wherein the tops of two corresponding moving wheels 2 are provided with placement rods 3, the two placement rods 3 are slidably connected with the four moving wheels 2, a motor 5 is fixedly installed on the front of the placement box 1, a disc 6 is fixedly installed on the output shaft of the motor 5, a short rod 7 is hingedly installed on the back of the disc 6, a round rod 8 is fixedly installed on the side where the two placement rods 3 are close to each other, both ends of the round rod 8 respectively pass through the placement rod 3, and the round rod 8 is hinged with the short rod 7.

[0025] The motor 5 drives the disc 6 to rotate, thereby causing the short rod 7 hinged to the disc 6 to swing. Since the short rod 7 is hinged to the round rod 8 on the placement rod 3, this swing will be converted into the sliding of the placement rod 3 on the moving wheel 2, thereby realizing the left and right reciprocating motion of the placement rod 3, thereby being able to drive the electroplated parts to move evenly in the electroplating solution, thereby ensuring that the electroplating solution can evenly cover the surface of the electroplated parts, improving the uniformity and quality of electroplating. Compared with the traditional device, the left and right reciprocating motion of the placement rod 3 can be automatically performed by the drive of the motor 5 without manual intervention, which greatly simplifies the operation process and improves production efficiency. By adjusting the speed and rotation direction of the motor 5, the reciprocating speed and amplitude of the placement rod 3 can be controlled to adapt to different electroplating requirements.

[0026] The staff first starts the motor three 22 through the control panel. The output shaft of the motor three 22 drives the threaded rod 23 to rotate through the belt two 24. The rotation of the threaded rod 23 causes the protective cover 26 threadedly connected thereto to move upward. The protective cover 26 is adjusted to a suitable position, and then the metal parts to be electroplated are placed in turn on the limit grooves 4 of the two placement rods 3. Then the motor three 22 is started again through the control panel to make the protective cover 26 move downward until it moves to a suitable position, ensuring the sealing of the plating solution in the plating tank and preventing external impurities from entering. Then the adjustable power supply 19 is turned on, and suitable electroplating parameters are set. A section of the metal wire frame 20 passes through the placement box 1 and is fixedly connected to the anode of the adjustable power supply 19. The metal wires 21 on the right sides of the two placement rods 3 are fixedly connected to the cathode of the adjustable power supply 19 to form an electroplating electrode. The circuit is then started by the control panel, and the output shaft of the motor 5 drives the disc 6 to rotate. The rotation of the disc 6 causes the short rod 7 hinged thereto to swing. The swing of the short rod 7 is converted into the sliding of the placement rod 3 on the moving wheel 2 through the round rod 8, thereby realizing the left and right reciprocating motion of the placement rod 3, thereby ensuring that the electroplating solution can evenly cover the surface of the electroplated part and improving the uniformity and quality of the electroplating. At the same time, the motor 2 12 is started through the control panel, and the output shaft of the motor 2 12 drives the gear 13 to rotate. The gear 13 is engaged with the gear 2 15, so that the rotating rod 14 rotates. The rotating rod 14 drives the two rotating rods 2 16 to rotate through the belt 17. The stirring blades 18 on the outer walls of the rotating rods 14 and 2 16 stir the electroplating solution to ensure that the ions in the electroplating solution are evenly distributed and improve the electroplating effect.

[0027] Among them, the front and back sides of the placement box 1 are respectively fixedly installed with fixed plates 27, the top of the front fixed plate 27 is fixedly installed with a motor three 22, the top of the front fixed plate 27 is rotatably installed with a threaded rod 23, the outer wall of the threaded rod 23 and the output shaft of the motor three 22 are both wrapped with a belt two 24, and the outer wall of the threaded rod 23 is threadedly installed with a protective cover 26.

[0028] The protective cover 26 of the electroplating tank can be automatically raised and lowered by the motor 3 22. The automatic raising and lowering adjustment of the protective cover 26 can avoid potential safety hazards caused by improper manual operation. At the same time, the tight closure of the protective cover 26 can also prevent the electroplating solution from splashing out or external impurities from entering the electroplating tank, ensuring the safety and stability of the electroplating process. Compared with the traditional device, the electroplating tank can be prevented from splashing out or external impurities from entering due to human factors during operation, thereby causing safety accidents. The lifting and adjusting protective cover 26 not only effectively avoids the occurrence of these problems, but also improves the safety of the electroplating process.

[0029] The outer walls of the two placement rods 3 are respectively provided with limiting grooves 4, and the limiting grooves 4 are distributed in an array with equal distances from left to right.

[0030] By providing the limiting groove 4 on the outer wall of the placement rod 3, the electroplated part is placed in the limiting groove 4, so that it can maintain a stable position during the electroplating process, and will not move or tilt due to the flow of the electroplating solution or other factors. This stability is crucial to obtain a high-quality electroplating layer, and prevents the electroplating layer from being uneven, incomplete or peeling.

[0031] Among them, a mounting frame 9 is fixedly installed on the top of the placement box 1, a motor protection shell 10 is fixedly installed on the top of the mounting frame 9, a motor 2 12 is fixedly installed on the top of the mounting frame 9, a gear 13 is fixedly sleeved on the output shaft of the motor 2 12, a rotating rod 14 is rotatably installed on the top of the mounting frame 9, the bottom end of the rotating rod 14 passes through the mounting frame 9 and extends into the placement box 1, and a gear 2 15 is fixedly sleeved on the outer wall of the rotating rod 14, and the gear 2 15 is meshed with the gear 13.

[0032] Through the meshing of gear 13 and gear 2 15, the power of motor 2 12 can be stably transmitted to rotating rod 14, ensuring that rotating rod 14 can rotate smoothly and reliably. The design of motor protection shell 10 can protect motor 2 12 from external environment such as splashing of plating liquid, dust, etc., thereby extending the service life of motor 2 12.

[0033] Among them, a rectangular protective shell 11 is fixedly installed at the bottom of the mounting frame 9, a rotating rod 14 penetrates the rectangular protective shell 11 and is rotatably connected to the rectangular protective shell 11, two rotating rods 2 16 are rotatably installed at the bottom of the mounting frame 9, and belts 17 are respectively wrapped around the outer walls of the two rotating rods 2 16 and the outer walls of the rotating rod 1 14, and the bottom ends of the two rotating rods 2 16 penetrate the rectangular protective shell 11 and are rotatably connected to the rectangular protective shell 11, and a number of stirring blades 18 are respectively fixedly installed on the outer walls of the two rotating rods 2 16 and the rotating rod 1 14.

[0034] Through the rotation of the stirring blade 18, the chemical components in the electroplating solution can be evenly mixed, avoiding the problem of uneven concentration due to precipitation or stratification, thereby ensuring the uniformity and quality of the electroplating layer. By adopting a linkage mechanism, the rotation of the rotating rod 14 can simultaneously drive the two rotating rods 16 to rotate, thereby achieving comprehensive stirring of the electroplating solution and improving the stirring efficiency. The design of the rectangular protective shell 11 protects the internal stirring mechanism and avoids damage caused by external factors.

[0035] Among them, an adjustable power supply 19 is fixedly installed on the right outer wall of the placement box 1, and a metal wire frame 20 is arranged inside the placement box 1. A section of the metal wire frame 20 passes through the placement box 1 and is fixedly connected to the anode of the adjustable power supply 19. Metal wires 21 are fixedly installed on the right sides of the two placement rods 3, and the bottom ends of the metal wires 21 are fixedly connected to the cathode of the adjustable power supply 19.

[0036] The adjustable power supply 19 provides stable current and voltage for the electroplating process, ensuring the uniformity of the electroplating. The metal wire frame 20 and the metal wire 21 serve as electrodes, which are respectively connected to the anode and cathode of the adjustable power supply 19, so that the current can be evenly distributed on the workpiece to be plated in the electroplating tank, avoiding the problem of uneven thickness of the electroplating layer caused by uneven current distribution. The introduction of the adjustable power supply 19 allows the current and voltage in the electroplating process to be adjusted according to actual needs.

[0037] A limiting slide bar 25 is fixedly installed on the top of the fixing plate 27 on the back side. The limiting slide bar 25 passes through the protective cover 26 and is slidably connected to the protective cover 26 .

[0038] By setting the limiting slide bar 25, a stable sliding track is provided for the opening and closing of the protective cover 26, making the operation smoother and easier to control, avoiding the possible deviation or shaking of the protective cover 26 during operation, and ensuring the accuracy and safety of the operation.

[0039] The bottom of the protective cover 26 is grooved, and the area of ​​the groove is larger than the floor area of ​​the placement box 1 , and also larger than the sum of the areas of all accessories fixedly mounted on the outer wall of the placement box 1 .

[0040] By designing the notch area at the bottom of the protective cover 26 to be large enough, it not only covers the bottom area of ​​the placement box 1, but also takes into account all the accessories fixedly installed on the outer wall of the placement box 1. This design ensures that during the electroplating process, both the placement box itself and the various accessories thereon can be fully protected, avoiding interference from external factors such as dust, moisture, impurities, etc., thereby ensuring the purity and quality of the electroplating.

[0041] The working principle and use process of this utility model:

[0042] The staff first starts the motor three 22 through the control panel. The output shaft of the motor three 22 drives the threaded rod 23 to rotate through the belt two 24. The rotation of the threaded rod 23 causes the protective cover 26 threadedly connected thereto to move upward. The protective cover 26 is adjusted to a suitable position, and then the metal parts to be electroplated are placed in turn on the limit grooves 4 of the two placement rods 3. Then the motor three 22 is started again through the control panel to make the protective cover 26 move downward until it moves to a suitable position, ensuring the sealing of the plating solution in the plating tank and preventing external impurities from entering. Then the adjustable power supply 19 is turned on, and suitable electroplating parameters are set. A section of the metal wire frame 20 passes through the placement box 1 and is fixedly connected to the anode of the adjustable power supply 19. The metal wires 21 on the right sides of the two placement rods 3 are fixedly connected to the cathode of the adjustable power supply 19 to form an electroplating electrode. The circuit is then started by the control panel, and the output shaft of the motor 5 drives the disc 6 to rotate. The rotation of the disc 6 causes the short rod 7 hinged thereto to swing. The swing of the short rod 7 is converted into the sliding of the placement rod 3 on the moving wheel 2 through the round rod 8, thereby realizing the left and right reciprocating motion of the placement rod 3, thereby ensuring that the electroplating solution can evenly cover the surface of the electroplated part and improving the uniformity and quality of the electroplating. At the same time, the motor 2 12 is started through the control panel, and the output shaft of the motor 2 12 drives the gear 13 to rotate. The gear 13 is engaged with the gear 2 15, so that the rotating rod 14 rotates. The rotating rod 14 drives the two rotating rods 2 16 to rotate through the belt 17. The stirring blades 18 on the outer walls of the rotating rods 14 and 2 16 stir the electroplating solution to ensure that the ions in the electroplating solution are evenly distributed and improve the electroplating effect.
