Description

Technical Field

[0001] This utility model relates to the field of electroplating stirring technology, specifically to an auxiliary stirring device for electroplating. Background Technology

[0002] In electroplating, the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis, aims to improve the corrosion resistance of the metal, enhance its aesthetics, and improve the durability of the product. In this process, stirring plays a crucial role in the electroplating effect. Stirring promotes the uniform distribution of the electroplating solution, ensuring that all parts of the surface of the object being plated receive sufficient and consistent electroplating treatment, thereby significantly improving the electroplating quality, reducing the probability of uneven plating, bubbles, and other problems, and ensuring that the product meets strict quality standards.

[0003] However, traditional auxiliary stirring equipment for electroplating has many drawbacks. On the one hand, some traditional stirring equipment lacks sufficient stirring force, making it difficult to achieve comprehensive and thorough uniform mixing of the electroplating solution in a large electroplating tank. This results in differences in the concentration of various components in the electroplating solution in different areas, ultimately causing inconsistent coating thickness on the plated objects and seriously affecting the consistency of product quality. On the other hand, some traditional stirring equipment consumes a lot of energy during operation, which not only increases the production costs of enterprises but also does not conform to the current trend of energy conservation and environmental protection in industrial development. Moreover, traditional equipment often lacks a precise stirring speed control mechanism, making it impossible to flexibly adjust the stirring intensity according to the specific requirements of different electroplating processes. This further limits the optimization and innovation of electroplating processes and hinders the industry's development towards high quality and refinement. Therefore, we propose an auxiliary stirring device for electroplating. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an auxiliary stirring device for electroplating, which has the following beneficial effects:

[0015] 1. This auxiliary stirring device for electroplating significantly improves the stirring effect through its unique stirring structure design. The stirring motor drives the stirring shaft to rotate at high speed, which in turn drives multiple sets of circumferentially distributed stirring blades to powerfully stir the electroplating solution.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 An auxiliary stirring device for electroplating includes an electroplating tank 1. A set of symmetrical positioning rods 2 are fixedly installed at the center of the top of the electroplating tank 1. A support plate 3 is fixedly installed inside the positioning rods 2. A flow-blocking structure is provided on the side of the support plate 3. A through moving groove 6 is opened on the top of the support plate 3. A sliding structure is provided on both sides of the top of the support plate 3 corresponding to the moving groove 6. A fixed plate 8 is fixedly installed on one end face of the sliding structure. A rotating structure is provided on the fixed plate 8. A stirring structure is provided below the support plate 3.

[0025] Furthermore, the flow-blocking structure includes a first flow-blocking plate 4 and a second flow-blocking plate 5. The first flow-blocking plate 4 is fixedly installed on the top of the electroplating tank 1, and its side is fixedly connected to the support plate 3. The second flow-blocking plate 5 is fixedly connected to the other side of the support plate 3, and its bottom is fixedly installed on the top of the electroplating tank 1. During the electroplating process, when the object to be plated is placed into the electroplating tank 1, the first flow-blocking plate 4 and the second flow-blocking plate 5 can reduce the interference of electroplating liquid fluctuations caused by the object being placed into the tank on the stirring effect. In addition, the flow-blocking structure can also prevent the electroplating liquid from splashing out of the electroplating tank 1 to a certain extent, avoiding waste of electroplating liquid and pollution of the working environment, ensuring the safety of operators and the cleanliness of the working area. At the same time, due to its blocking effect, the vortex generated by stirring can be made more regular, making the circulation of the electroplating liquid in the stirring area more stable, improving the uniformity and stability of stirring, and further improving the electroplating effect.

[0026] Furthermore, the sliding structure includes a slide rod 7 and a slide plate 11. A set of symmetrical and parallel slide rods 7 are fixedly installed on the top of the support plate 3. The slide plate 11 is slidably installed on the top of the slide rods 7. A set of grooves 12 are opened at the bottom of the slide plate 11. The grooves 12 are connected to the slide rods 7. The side of the slide plate 11 is provided with threaded holes 13 corresponding to the grooves 12. The high-precision fit between the slide rods 7 and the grooves 12 not only ensures the smoothness of the slide plate 11 sliding, but also reduces friction loss during the sliding process and extends the service life of the equipment. During long-term use, this design ensures that the movement accuracy of the slide plate 11 is not greatly affected, and the stirring structure can always move accurately in the electroplating tank. The design of the threaded holes 13, in addition to cooperating with the lead screw 10 to realize the movement of the slide plate 11, also allows the staff to easily make fine adjustments to the position of the slide plate 11 by connecting some auxiliary tools through the threads during installation and debugging, ensuring that the stirring structure can accurately cover the area in the electroplating tank that needs to be stirred.

[0027] Furthermore, the rotating structure includes a moving motor 9 and a lead screw 10. The moving motor 9 is fixedly installed on the outside of the fixed plate 8, and the output shaft of the moving motor 9 is fixedly connected to the lead screw 10. The slide plate 11 is threaded onto the lead screw 10 through the threaded hole 13. As the power source of the rotating structure, the moving motor 9 has good torque characteristics and can stably drive the lead screw 10 to rotate under different load conditions. During the stirring process, if there are many impurities in the electroplating solution, which increases the moving resistance of the slide plate 11, the moving motor 9 can still maintain a stable output to ensure the normal movement of the stirring structure. The pitch of the lead screw 10 determines the accuracy of the distance the slide plate 11 moves each time. A suitable pitch ensures that the moving speed of the stirring structure in the electroplating tank can meet the needs of comprehensive stirring without being too fast and causing uneven stirring, thereby achieving effective stirring coverage of different areas in the electroplating tank.

[0028] Furthermore, the stirring structure includes a stirring motor 14, a stirring shaft 15, and stirring blades 16. The stirring motor 14 is fixedly installed on the top of the slide plate 11. The output shaft of the stirring motor 14 passes through the slide plate 11 and is fixedly connected to the stirring shaft 15. Multiple sets of circumferentially distributed stirring blades 16 are fixedly installed on the outer side of the stirring shaft 15. A scraper structure is rotatably installed on the bottom of the stirring shaft 15. The stirring motor 14 adopts high-efficiency and energy-saving motor technology, which reduces energy consumption while ensuring strong stirring power output, meeting the requirements of modern industrial energy conservation and environmental protection. The shape and angle of the stirring blades 16 are specially designed. Their unique curved shape can generate water flow in different directions during stirring, enhancing the disturbance effect on the electroplating solution and promoting more thorough mixing of the electroplating solution. Moreover, the stirring blades 16 are made of wear-resistant and corrosion-resistant materials, which are not easily damaged when in contact with the electroplating solution for a long time, reducing the maintenance cost of the equipment and ensuring the stability of the stirring effect.

[0029] Furthermore, the scraper structure includes a bearing 17, a connecting plate 18, and scraper shafts 19. The bearing 17 is fixedly installed at the bottom of the stirring shaft 15, and the connecting plate 18 is rotatably installed on the outside of the bearing 17. Multiple sets of linearly distributed scraper shafts 19 are fixedly installed at the bottom of the connecting plate 18. The bearing 17 is made of a low-friction coefficient material, which can effectively reduce the frictional resistance between the stirring shaft 15 and the connecting plate 18 when rotating, making the scraper shafts 19 rotate and scrape the bottom of the electroplating tank more smoothly and reducing energy loss. The connecting plate 18 has a certain degree of elasticity, which can play a buffering role when the scraper shafts 19 come into contact with uneven areas at the bottom of the electroplating tank, preventing the scraper shafts 19 from being damaged due to uneven force. At the same time, it can also ensure that the scraper shafts 19 are always in close contact with the bottom of the tank, improving the scraping effect. The number and distribution spacing of the scraper shafts 19 have been optimized so that they can fully cover the bottom of the electroplating tank without causing excessive resistance due to too small a spacing, ensuring effective cleaning of the sediment at the bottom of the tank and maintaining the uniformity of the electroplating solution composition.

[0038] Slide 11: Slide 11 is connected to slide rod 7 via slide groove 12, and a stirring motor 14 is installed on the top. The side has threaded hole 13 that cooperates with lead screw 10 to realize the movement of the stirring structure in the electroplating tank.

[0039] Fixed plate 8: Fixed plate 8 is fixed to one end face of slide plate 11 and is used to install rotating structural components such as moving motor 9, providing an installation base for the rotating structure and ensuring the stability of the rotating structure;

[0040] Mobile motor 9: The mobile motor 9 is installed on the outside of the fixed plate 8 and serves as the power source for the rotating structure. It drives the lead screw 10 to rotate, thereby moving the slide plate 11 and adjusting the position of the stirring structure.

[0041] Lead screw 10: Lead screw 10 is connected to the output shaft of the moving motor 9 and is threaded to the threaded hole 13 on the side of the slide plate 11. The slide plate 11 is moved by rotation, which controls the moving distance and speed of the stirring structure.

[0042] Slide 12: Slide 12 is located at the bottom of slide plate 11 and cooperates with slide rod 7 to enable slide plate 11 to slide smoothly along slide rod 7, ensuring the stability of the stirring structure during movement;

[0043] Threaded hole 13: Threaded hole 13 is provided on the side of slide plate 11 and cooperates with lead screw 10 to realize the movement of slide plate 11 when lead screw 10 rotates. It is the key connection point for the linkage between rotating structure and sliding structure.

[0044] Stirring motor 14: The stirring motor 14 is installed on the top of the slide plate 11 and serves as the power source for the stirring structure. It drives the stirring shaft 15 to rotate, providing power for stirring the electroplating solution, and the speed is adjustable.

[0045] Stirring shaft 15: The stirring shaft 15 is connected to the output shaft of the stirring motor 14, the stirring blades 16 are installed on the outside, and the scraper structure is connected to the bottom to transmit stirring power and drive the stirring blades and scraper to work;

[0046] Stirring blade 16: The stirring blade 16 is installed on the outside of the stirring shaft 15 and is distributed in a circle. It cuts the electroplating solution by high-speed rotation, generates stirring force, and promotes uniform mixing of the electroplating solution.

[0047] Bearing 17: The bearing 17 is installed at the bottom of the stirring shaft 15, connecting the stirring shaft 15 and the connecting plate 18, reducing the frictional resistance between the two, and making the scraper shaft 19 rotate more smoothly;

[0048] Connecting plate 18: The connecting plate 18 is rotatably connected to the stirring shaft 15 through the bearing 17, and the scraper shaft 19 is installed at the bottom, which serves to connect the stirring shaft 15 and the scraper shaft 19 and ensure that the scraper shaft 19 can work normally;

[0049] Scraper 19: The scraper 19 is fixed to the bottom of the connecting plate 18 and is linearly distributed. It rotates along with the stirring shaft 15 when it rotates, scraping the bottom of the electroplating tank to prevent the accumulation of sediment.

[0050] Working Principle: When the equipment starts, the stirring motor 14, as the core power source, begins to operate. The output shaft of the stirring motor 14 drives the stirring shaft 15 to rotate at high speed. The stirring blades 16 distributed around the outer circumference of the stirring shaft 15 rotate accordingly. These stirring blades 16 rapidly cut through the electroplating solution, generating a strong stirring force that causes the electroplating solution to flow and mix. The special design and distribution of the stirring blades 16 ensures that the electroplating solution is agitated in all directions during the rotation of the stirring shaft 15, promoting the mutual integration of various components in the electroplating solution and avoiding uneven component concentration. During the stirring process, to achieve more comprehensive stirring coverage, the rotating structure and the sliding structure work together, and the moving motor 9... Fixed to the outside of the fixed plate 8, when the moving motor 9 starts, its output shaft drives the lead screw 10 to rotate. The lead screw 10 is threadedly connected to the threaded hole 13 on the side of the slide plate 11. The rotation of the lead screw 10 causes the slide plate 11 to slide along the slide rod 7 on the top of the support plate 3. The slide rod 7 and the slide groove 12 at the bottom of the slide plate 11 cooperate to ensure that the slide plate 11 slides smoothly. In this way, the stirring structure can move left and right in the electroplating tank, expanding the stirring range and making the stirring effect more uniform. For example, in a large electroplating tank, the movement of the stirring structure can ensure that the electroplating liquid in all corners of the electroplating tank can be fully stirred, solving the problems of insufficient stirring force and uneven stirring in traditional equipment. The flow-blocking structure also plays an important role in the entire working process. To achieve their intended function, the first baffle plate 4 and the second baffle plate 5 are fixed to the top of the electroplating tank 1 and both sides of the support plate 3, respectively. Their presence effectively reduces unnecessary flow and energy loss of the electroplating solution during stirring. When the stirring blades 16 stir the electroplating solution, the baffle structure guides the solution to flow along a more efficient path, concentrating the stirring energy for mixing and improving stirring efficiency. Simultaneously, the baffle structure stabilizes the flow of the electroplating solution, preventing eddies and other conditions detrimental to uniform stirring. The scraper structure at the bottom of the stirring shaft 15 also has a unique function. The bearing 17 is installed at the bottom of the stirring shaft 15, and the connecting plate 18 is rotatably connected to the stirring shaft 15 via the bearing 17. The scraper shaft 19 at the bottom of the 18 rotates along with the stirring shaft 15. The scraper shaft 19 can scrape the bottom of the electroplating tank to prevent the sediment in the electroplating solution from accumulating at the bottom of the tank and affecting the electroplating effect. During the stirring process, the scraper shaft 19 continuously cleans the bottom of the tank, allowing the sediment to re-participate in the mixing and ensuring the uniformity of the electroplating solution composition. The stirring motor 14 has the ability to adjust the stirring speed. When performing a fine electroplating process with low requirements for stirring intensity, the speed of the stirring motor 14 can be reduced by the control system to avoid excessive stirring from negatively affecting the electroplating effect. In processes that require rapid mixing of the electroplating solution, the speed of the stirring motor 14 can be quickly increased to meet the stirring intensity requirements of different electroplating processes.
