Description

Technical Field

[0001] This application relates to the technical field of workpiece surface treatment, and in particular to a plating device for the horizontal surface of workpieces. Background Art

[0002] Electroplating processing, as one of the common surface treatment processes in modern industry, is widely used in fields such as metal anti-corrosion, improving wear resistance, and enhancing appearance. Through the electrolysis principle, a metal workpiece is placed in an electroplating solution containing specific chemical components, and metal ions are deposited on the workpiece surface under the action of an electric current to form a coating. This technology plays an important role in improving product performance and extending service life, and is particularly valuable in industries such as electronics, automotive, and aerospace.

[0003] In practical applications, in order to achieve efficient electroplating treatment of thin sheet workpieces, usually two methods are adopted: suspension electroplating or immersion electroplating. Suspension electroplating fixes the workpiece through a hanging rack and immerses it in the electroplating tank, which is suitable for workpieces with a larger thickness; while immersion electroplating directly places the workpiece in the electroplating solution, and is commonly used for the treatment of small or thin workpieces. In addition, there are also some simple immersion devices operated manually, where the workpieces are individually placed into the electroplating solution by hand to complete the treatment.

[0004] However, the existing immersion electroplating devices have obvious deficiencies when dealing with thin sheet workpieces. Due to the thin thickness and easy deformation of the thin sheets, the traditional hanging rack fixing method is difficult to apply, and manual operation has low efficiency and is prone to causing personal injuries. At the same time, the existing devices cannot achieve continuous production, resulting in low production efficiency and high labor intensity, and it is difficult to meet the requirements of large-scale industrial production. Summary of the Invention

[0005] The purpose of this application is to provide a plating device for the horizontal surface of workpieces, which can achieve efficient and automated plating treatment of thin sheet workpieces.

[0006] The above technical purpose of this application is achieved through the following technical solutions: A plating device for the horizontal surface of workpieces, comprising: A frame; An installation tank body, arranged on the frame, and a water outlet is provided in the installation tank body; A transmission component, arranged in the installation tank body, for driving the workpiece to move horizontally in the installation tank body; A plurality of accommodation tank bodies, arranged at intervals along the transmission direction of the transmission component, a water inlet is provided in the accommodation tank body, a material passing gap is provided on the tank wall of the accommodation tank body, and the workpiece enters or exits the accommodation tank body through the material passing gap; A plurality of conductive bars are arranged at equal intervals along the transmission direction of the transmission assembly, and the intervals between adjacent conductive bars are adjustable. The conductive bars are used to continuously and stably provide current to the workpiece during the coating process; A liquid supply assembly is disposed on the frame and is connected to the water inlet through an independent plating liquid pipeline for accurate supply of plating liquid; and is selectively connected to the water inlet through an independent cleaning liquid pipeline to meet liquid requirements at different stages; The drainage assembly is arranged on the frame and is connected with the water outlet through a pipeline.

[0007] By adopting the above technical scheme, the frame provides a stable support for the whole device, the water outlet of the trough is installed to ensure the smooth discharge of liquid, the transmission component can stably drive the workpiece to move in the horizontal direction, and cooperate with the spaced accommodating trough and its material passing gap to realize an efficient and orderly plating process of the workpiece, which greatly improves the degree of automation of production; the conductive rods with adjustable spacing ensure that workpieces of different sizes can obtain current continuously and stably during the plating process, effectively avoid problems such as plating leakage and uneven plating, and greatly improve the plating quality. In addition, the independent plating liquid pipeline and cleaning liquid pipeline of the liquid supply component are connected to the water inlet respectively, which can not only accurately supply plating liquid to meet the requirements of the plating process, but also switch the cleaning liquid for subsequent cleaning as needed. Combined with the drainage component, the waste liquid is discharged in time, so that the whole device runs smoothly and is fully functional, which fully meets the modern industry's requirements for efficient and high-quality surface plating treatment of workpieces.

[0008] Optionally, the transmission assembly includes: A drive motor, mounted on the frame, having a speed control function, and used to output stable and adaptive transmission power; A driving shaft connected to an output end of the driving motor; A driving bevel gear set, which is composed of a plurality of driving bevel gears evenly spaced and arranged on the driving shaft; A transmission shaft group, comprising a plurality of transmission shafts arranged in parallel, arranged in the installation slot body, both ends of each transmission shaft being arranged on the slot wall of the installation slot body through a bearing seat, and the transmission shaft is used to carry a workpiece; The driven bevel gear set is composed of driven bevel gears respectively installed at two ends of the transmission shaft, and each of the driven bevel gears is meshed with the corresponding driving bevel gear.

[0009] By adopting the above technical solution, the drive motor is installed on the frame and has a speed regulation function, enabling it to accurately output stable and suitable driving power according to the materials, sizes of different workpieces and the precise requirements of the plating process, ensuring that the rhythm of the entire plating process is just right. The reliable connection between the driving shaft and the output end of the drive motor guarantees the efficient transmission of power. The driving bevel gear sets evenly spaced on the driving shaft, in cooperation with the driven bevel gear sets composed of driven bevel gears precisely meshing with the driving bevel gears, and the transmission shaft sets arranged in the installation groove body and stably supported at both ends by bearing seats, not only achieve the smooth distribution and conversion of power, enabling multiple transmission shafts to rotate in unison, but also provide a solid and stable support for the workpiece being carried, ensuring that the workpiece maintains an accurate position and a stable posture during horizontal movement, effectively avoiding problems such as uneven plating thickness and surface defects caused by unstable transmission, and greatly improving the plating quality and production efficiency.

[0010] Optionally, a pressing plate is provided on the accommodating groove body, and a plurality of through holes are provided on the pressing plate. The pressing plate cooperates with the transmission shaft set to form an adaptive gap to limit the workpiece passing through.

[0011] By adopting the above technical solution, when the workpiece is being plated, the pressing plate provided on the accommodating groove body plays a key limiting role. The adaptive gap formed between the pressing plate and the transmission shaft set can accurately match the size of the workpiece, effectively restricting the workpiece from above, preventing the workpiece from bouncing up and down or shifting during horizontal movement and when contacting the plating solution, and ensuring that the workpiece is always in an ideal plating position. The plurality of through holes on the pressing plate are carefully designed. They neither hinder the smooth passage of the plating solution, enabling the plating solution to fully wet all surfaces of the workpiece to ensure the uniformity of the plating, nor can they provide a discharge channel for the gas that may be generated during the electroplating process, avoiding bubbles adhering to the surface of the workpiece and affecting the plating quality, comprehensively improving the accuracy, flatness and overall quality of the plating, and providing a strong guarantee for high-quality workpiece plating treatment.

[0012] Optionally, a pressure roller is provided on the accommodating groove body corresponding to the transmission shaft close to the material passing gap. A driving gear is fixedly provided on the transmission shaft, and a driven gear matching the driving gear is fixedly provided on the pressure roller. The driving gear and the driven gear mesh with each other to achieve the synchronous rotation of the pressure roller and the transmission shaft.

[0013] By adopting the above technical solution, in the key link of the workpiece passing through the feeding gap, the pressure roller correspondingly arranged on the accommodating tank body is closely matched with the transmission shaft, playing an important role. Since the driving gear on the transmission shaft and the driven gear precisely matched with it on the pressure roller are meshed with each other, the synchronous rotation of the two is realized, which enables the pressure roller to cooperate with the transmission shaft. On the one hand, it provides stable support for the workpiece from below, effectively preventing the workpiece from jumping, shifting and other unstable conditions due to uneven force or inertia when entering the accommodating tank body, and ensuring the smooth transition of the workpiece. On the other hand, it continuously maintains the restraint on the workpiece during the plating process, making it maintain an accurate position in the plating solution, enabling the plating solution to act evenly on the surface of the workpiece, avoiding problems such as inconsistent coating thickness and surface defects caused by the shaking of the workpiece, significantly improving the uniformity, integrity and quality of the coating, and strongly promoting the efficient and stable operation of the production process.

[0014] Optionally, the setting distance between adjacent conductive bars is equal to the length of the workpiece.

[0015] By adopting the above technical solution, the setting distance between adjacent conductive bars is accurately set to be equal to the length of the workpiece, ensuring that during the plating process, no matter where the workpiece is located, at least one conductive bar can be in contact with the workpiece, continuously and stably providing current for the workpiece. It effectively avoids the current interruption or instability caused by poor conductive contact, completely eliminates the problem of missing plating, and enables the coating to evenly and completely cover the surface of the workpiece. At the same time, this precisely matched design does not require additional complex current regulation or optimization of the conductive structure, simplifies the device structure, reduces the production cost and maintenance difficulty, greatly improves the coating quality and production efficiency, and lays a solid foundation for the large-scale industrial production of high-quality coated workpieces.

[0016] Optionally, a flow distribution plate is provided in the accommodating tank body, and a plurality of flow distribution holes are provided on the flow distribution plate, and the flow distribution plate is arranged corresponding to the water inlet.

[0017] By adopting the above technical solution, when the plating solution surges into the accommodating tank body from the water inlet, the flow distribution plate, with its reasonably arranged plurality of flow distribution holes, quickly disperses the concentrated plating solution, making the plating solution evenly flow to all corners of the accommodating tank body. This effectively avoids the problems of too high or too low local plating solution concentration caused by uneven flow rate and concentrated flow direction of the plating solution, ensuring that the whole body of the workpiece is wrapped by the plating solution with appropriate concentration and stable flow. The uniform and stable plating solution environment not only ensures the consistency of the coating thickness, makes the coating on the surface of the workpiece smoother, reduces defects such as pits and wrinkles, but also improves the uniformity of metal ion deposition, enhances the bonding force between the coating and the workpiece, and comprehensively improves the coating quality, laying a solid foundation for the high-performance use of the subsequent workpiece.

[0018] Optionally, it further includes a cleaning component, which is arranged in the installation groove and at the conveying end of the transmission component.

[0019] By adopting the above technical solution, a cleaning component is arranged at the conveying end of the transmission component, which can perform cleaning operations in a timely manner after the workpiece is completed with the plating treatment. At this time, there may be excess plating solution or impurities remaining on the surface of the workpiece. The presence of the cleaning component can effectively prevent these residual substances from drying or undergoing chemical reactions on the surface of the workpiece, thereby affecting the appearance and performance of the workpiece. At the same time, the cleaning component is arranged in the installation groove, making the entire device structure compact, facilitating the unified management and recycling of liquids such as plating solution and cleaning solution. This not only saves space but also helps to keep the working environment clean, reducing the corrosion and pollution of surrounding equipment. In addition, this setting method matches the technological process of the entire plating device, realizing the orderly connection between plating and cleaning, improving production efficiency, and ensuring the stability of the workpiece plating quality.

[0020] Optionally, the cleaning component includes: A water inlet pipe, fixedly arranged on the frame. One end of the water inlet pipe is communicated with an external water source, and the other end extends above the installation tank body; A plurality of cleaning nozzles, evenly distributed along the length direction of the water inlet pipe. The spraying direction of the cleaning nozzles faces the surface of the workpiece, and is used to spray cleaning liquid onto the workpiece to clean the residual plating solution or impurities on its surface; A baffle plate, arranged in the installation tank body, used to block the splashing cleaning liquid during the cleaning process, guide the cleaning liquid to flow back to the drainage component, and prevent the cleaning liquid from polluting other components; when the water inlet of the accommodating tank body is introduced with cleaning liquid, the clear water flushes the workpiece from one side of the workpiece, and the cleaning nozzles spray cleaning liquid from the other side of the workpiece.

[0021] By adopting the above technical solution, the water inlet pipe is fixed to the frame and connected to the external water source. It extends to the top of the installation tank, providing a stable cleaning liquid delivery path for the cleaning operation and ensuring the continuity of the cleaning process. Several cleaning nozzles distributed along the pipe accurately spray cleaning liquid toward the surface of the workpiece. With multi-angle and all-round coverage, it can strongly wash away the plating liquid and impurities remaining on the surface of the workpiece, greatly improving the thoroughness of cleaning. The baffle installed in the tank is like a solid line of defense, effectively blocking the cleaning liquid splashing around during the cleaning process, guiding the liquid to flow back to the drainage component smoothly, realizing the recycling and environmental protection of the cleaning liquid, and effectively avoiding the corrosion and pollution of the cleaning liquid to other key components such as the transmission component and the conductive rod, thereby extending the service life of the equipment. Furthermore, when the cleaning liquid is introduced into the water inlet of the tank to cooperate with the nozzle operation, the double-sided clamping cleaning mode is formed, which exerts force from both sides of the workpiece at the same time, further enhancing the cleaning efficiency, allowing the workpiece to quickly and efficiently restore to a clean state, providing a strong guarantee for subsequent processes or finished product packaging, and comprehensively optimizing the post-processing link of the entire coating device.

[0022] In summary, this application has at least the following beneficial effects: 1. The rack, mounting trough, transmission assembly, containing trough and other structures work together to realize orderly and efficient automatic transmission of workpieces in the device. With the conductive bars with adjustable spacing, it can meet the continuous and stable coating requirements of workpieces of different sizes, reduce manual intervention, and greatly improve production efficiency. It has significant advantages over traditional manual immersion and other methods.

[0023] 2. The pressure plate and the transmission shaft group form an adaptive gap, and the pressure roller and the transmission shaft rotate synchronously, which effectively stabilizes the position of the workpiece and prevents displacement and shaking during the coating process; the flow distribution plate evenly disperses the plating solution to avoid uneven concentration; the precisely set conductive bar spacing ensures stable power supply, and the synergistic effect of multiple aspects makes the coating thickness uniform and the surface smooth, eliminating quality problems such as missed plating and pitting.

[0024] 3. The cleaning component is set at the end of the transmission to promptly remove residual plating liquid impurities on the workpiece surface to avoid subsequent adverse effects; the baffle protection and double-sided clamping cleaning mode improve the cleaning effect, while preventing the splashing of the cleaning liquid from causing corrosion and pollution to other components, extending the overall life of the equipment, reducing maintenance costs, and ensuring long-term and stable operation of the device.
