Description

Technical Field

[0001] This application relates to the field of metal electroplating technology, and in particular to a continuous silver plating production line. Background Technology

[0002] Due to its excellent conductivity, reflectivity and corrosion resistance, electroplated silver has important applications in high-end electronic components and decorative items.

[0003] In related technologies, the industry generally uses single-tank electroplating machines or semi-automatic electroplating lines. The former involves manually placing parts into the electroplating tank, completing the electroplating process, and then removing them. It is simple to operate but inefficient. The latter uses overhead cranes or conveyor belts to transfer parts between different tanks, but still requires manual intervention, and the coordination between tanks is poor.

[0004] Existing silver electroplating production equipment suffers from the following problems: low production efficiency, high labor input, and difficulty in achieving large-scale continuous production. Utility Model Content

[0005] To improve production efficiency, this application provides a continuous silver plating production line.

[0006] The continuous silver plating production line provided in this application adopts the following technical solution: A continuous silver plating production line includes a frame, multiple silver plating tanks spaced apart on the frame, washing tanks respectively located at both ends of the frame, multiple electroplating rollers loaded with parts to be processed, and a mobile trolley for gripping the electroplating rollers and moving them along the frame. Each electroplating roller has a built-in cathode discharge device, and an anode placement box is provided between two adjacent silver plating tanks.

[0007] By adopting the above scheme, the mobile crane automatically transfers the electroplating roller along the frame between the loading end water washing tank, multiple silver plating tanks, and the unloading end water washing tank. After electrolysis by the anode placement box and the cathode discharge device, a uniform silver plating layer is formed on the surface of the parts, and excess electrolyte is removed in the water washing tank, which effectively improves production efficiency.

[0008] Preferably, a partition is provided in the middle of the washing tank, which divides the washing tank into two chambers, each of which can independently accommodate the electroplating roller entering and exiting.

[0009] By adopting the above solution, the staged cleaning requirements of electroplating drums are met, the risk of cross-contamination by residual electrolyte is reduced, and cleaning quality is improved while equipment waiting time is reduced. Preferably, the partition is a filter plate structure.

[0010] By adopting the above method, particulate impurities in the cleaning water can be intercepted and absorbed, reducing the likelihood of reduced cleaning effectiveness due to water quality degradation during reuse. Preferably, the electroplating roller is fixedly connected by two symmetrically arranged side plates, and two opposing support rods are arranged through the two side plates. The frame is provided with matching plug-in seats for the parts of the two support rods that extend out of the side plates.

[0011] By adopting the above solution, the positioning accuracy and operational stability of the electroplating roller are improved, and problems such as uneven coating thickness or part collision caused by vibration and offset are reduced.

[0012] Preferably, the roller is provided with a drive assembly, which includes a drive shaft movably connected between the two side plates via bearings, a drive wheel rotatably connected to both ends of the drive shaft, a driven wheel disposed at both ends of the electroplating roller and meshing with the drive wheel, and a drive motor externally connected to the drive shaft.

[0013] By adopting the above scheme, the drive motor drives the driving wheel to rotate through the drive shaft, and the driving wheel meshes with the driven wheel to ensure that both sides of the drum operate synchronously.

[0014] Preferably, a lifting rod is fixed between the two side plates for cooperating with the mobile crane to grab the electroplating roller, and the lifting rod, the support rod and the electroplating roller are arranged at intervals from top to bottom in the vertical direction.

[0015] By adopting the above scheme, a vertically spaced structure is formed. When the moving trolley grabs the electroplating drum by the lifting rod, the support rod, as an intermediate force-bearing layer, can disperse mechanical stress and reduce the risk of drum deformation.

[0016] Preferably, a water control bracket is provided on the side of the washing tank at the unloading end of the scaffold.

[0017] By adopting the above method, the electroplating roller is suspended on the water control rack after it comes out of the silver plating tank for static water control in order to remove residual electrolyte.

[0018] Preferably, it also includes a switch module, which is integrated into the side wall of the loading end of the gantry, and the switch module is electrically connected to the mobile trolley, the anode placement box, the cathode discharge device and the drive motor.

[0019] By adopting the above solution, operators can start or stop equipment operation with one click, realizing functional integration and linkage control, and reducing the need for manual intervention.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The mobile crane automatically transfers the electroplating rollers along the frame between the washing tank, the silver plating tank, and the washing tank. After electrolysis by the anode placement box and the cathode discharge device, the parts are cleaned of excess electrolyte in the washing tank and then the rolling electroplating is completed, which effectively improves production efficiency. 2. Improved the electroplating quality of the parts; 3. It has improved the automation level of the device and reduced human intervention. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a continuous silver plating production line. (Refer to...) Figure 1-2 A continuous silver plating production line includes a frame 1, a plurality of silver plating tanks 13 spaced apart on the frame 1, a washing tank 12 fixed at both ends of the frame 1, a plurality of electroplating rollers 3 loaded with parts to be processed, and a mobile trolley 2 for gripping the electroplating rollers 3 and moving them along the frame 1. The electroplating rollers 3 have a built-in cathode discharge device (not shown in the figure), and an anode placement box 14 is provided between two adjacent silver plating tanks 13.

[0027] Correspondingly, the mobile crane 2 picks up the electroplating roller 3 containing the parts to be processed, and first enters the water washing tank 12 at the loading end of the frame 1 for surface cleaning to remove impurities such as oil and oxides, ensuring the adhesion of the subsequent plating layer. Then, the mobile crane 2 transfers the electroplating roller 3 to multiple silver plating tanks 13 arranged at intervals. Each silver plating tank 13 is filled with an electrolyte containing silver ions. The cathode discharge device built into the electroplating roller 3 is connected to an external power supply to form a cathode, which, together with the anode placement box 14 between adjacent silver plating tanks 13, forms a complete circuit.

[0028] Furthermore, after the equipment is powered on, the anode undergoes an oxidation reaction to release silver ions. Under the action of the electric field, the silver ions migrate to the cathode and are reduced and deposited on the surface of the parts to form a uniform plating layer. The electroplating roller 3, which has completed multiple silver plating processes, is transferred to the water washing tank 12 at the unloading end of the rack 1 to remove the residual electrolyte on the surface. Then, it is dried or subjected to other surface treatments, ultimately enabling the parts loaded inside the cylinder to obtain a smooth and dense silver plating layer.

[0029] In summary, this device, through the gantry 1 and the mobile trolley 2 forming a material transfer system, achieves precise positioning and sequential transfer of the electroplating roller 3 between the washing tank 12 and the silver plating tank 13, while simultaneously completing the directional migration of silver ions and deposition on the surface of the parts, effectively reducing manual intervention and comprehensively improving production efficiency.

[0030] Specifically, a partition 121 is fixed between the two washing tanks 12 to divide the washing tank 12 into two chambers 122, and each chamber 122 can accommodate the electroplating roller 3 to enter and exit independently.

[0031] Therefore, the two independent chambers 122 can repeatedly handle the pre-cleaning and final cleaning needs of the electroplating roller 3, reducing the risk of cross-contamination of residual electrolyte and improving cleaning quality.

[0032] Furthermore, it can also support simultaneous cleaning of two electroplating rollers at once, reducing equipment waiting time and increasing production line throughput.

[0033] Specifically, the baffle 121 adopts a filter plate structure, which can evenly distribute water flow, reduce local blockage or dead water areas in the tank, and at the same time intercept and absorb particulate impurities in the cleaning water, reduce the occurrence of water quality degradation during repeated use, thereby affecting the cleaning effect and improving water resource utilization.

[0034] Furthermore, the filter plate structure can also serve as a support layer, reducing the risk of deformation or collapse of the baffle 121 during long-term use and extending its service life.

[0035] On the other hand, the electroplating roller 3 is fixedly connected by two symmetrically arranged side plates 31. Two opposing support rods 33 are arranged through the two side plates 31. The frame 1 is equipped with a matching plug seat 15 corresponding to the part of the two support rods 33 that extends out of the side plates 31. In this embodiment, the plug seat 15 has a V-shaped slot structure. The end of the support rod 33 is inserted downward into the plug seat 15 to complete the locking.

[0036] Therefore, the two ends of the plug-in seat 15 and the support rod 33 are plugged into each other to realize the rapid positioning of the electroplating roller 3 on the frame 1, improve the positioning efficiency and accuracy, and reduce the lateral displacement of the roller during displacement or rolling through physical constraints, thereby reducing the risk of deformation caused by the resistance of the electrolytic electrolyte or the weight of the parts.

[0037] Furthermore, the two symmetrical side plates 31 form a rigid frame through the support rods 33, which evenly distributes the load of the electroplating roller 3, ensuring the stable operation of the electroplating roller 3 in the tank and reducing the problem of uneven coating thickness or part collision caused by unilateral offset.

[0038] In addition, a water control bracket 4 is installed next to the water washing tank 12 at the unloading end of the frame 1. After the electroplating roller 3 comes out of the last silver plating tank 13, the moving trolley 2 suspends it on the water control bracket 4 for static water control, so that the silver ions can complete the final deposition and crystallization on the surface of the parts, thereby enhancing the adhesion between the plating layer and the parts.

[0039] Meanwhile, allowing the water to stand still can significantly reduce the amount of residual electrolyte, thereby reducing the risk of continuous corrosion of the plating and parts, which could lead to damage to the product's appearance and a decrease in its protective performance.

[0040] In the process described above, refer to Figure 3 The electroplating drum 3 is provided with a drive assembly 34, which includes a drive shaft 342 movably connected between two side plates 31 via bearings, a drive wheel 343 rotatably connected to both ends of the drive shaft 342, a driven wheel 344 fixed to both ends of the electroplating drum 3 and meshing with the drive wheel 343, and a drive motor (not shown in the figure) externally connected to the drive shaft 342.

[0041] Therefore, the drive motor inputs torque through the drive shaft 342 to drive the drive wheel 343 to rotate. After the drive wheel 343 meshes with the driven wheel 344, it inputs power to the driven wheel 344, which in turn drives the drum to rotate synchronously. The gear transmission structure can ensure the continuity and directionality of power transmission and reduce the risk of step loss caused by unilateral force.

[0042] Meanwhile, the side plate 31 provides a stable mounting reference for the drive shaft 342, the bearing support reduces rotational friction resistance, and together with the plug-in seat 15, further disperses mechanical stress, reduces off-center load and vibration, and comprehensively enhances the torsional stiffness and operational stability of the overall structure.

[0043] Specifically, a lifting rod 32 is fixed between the two side plates 31 to cooperate with the mobile crane 2 to grab the electroplating roller 3, so as to realize the rapid displacement of the electroplating roller 3, shorten the time for it to enter and exit the silver plating tank 13, and improve the operating efficiency.

[0044] Furthermore, the lifting rod 32, the support rod 33, and the electroplating roller 3 are arranged vertically from top to bottom at intervals. By forming a double shock-absorbing structure, when the moving trolley 2 grabs the electroplating roller 3 through the lifting rod 32, the support rod 33 can act as an intermediate force-bearing layer to disperse mechanical stress, thereby improving dynamic load capacity and reducing the risk of roller deformation.

[0045] In addition, it also includes a switch module 11, which is integrated into the side wall of the loading end of the gantry 1. The mobile trolley 2, the anode placement box 14, the cathode discharge device and the drive motor are all electrically connected to the switch module 11.

[0046] Therefore, the switch module 11, together with the mobile crane 2, the anode placement box 14, the cathode discharge device and the drive motor, form an electrical control network that can synchronously start or stop the operation of each component. Through functional integration and linkage control, the process timing is precisely matched, thereby improving the equipment response speed and processing quality and reducing overall power consumption.

[0047] Furthermore, operators can start and stop the machine with a single button via the switch module 11, which improves convenience and automation, and further reduces the need for manual intervention.

[0048] The implementation principle of a continuous silver plating production line according to an embodiment of this application is as follows: The equipment forms a material transfer system through the frame 1 and the moving trolley 2. While realizing the precise positioning and sequential transfer of the electroplating roller 3 between the washing tank 12 and the silver plating tank 13, it works with the external anode placement box 14 and the built-in cathode discharge device to complete the directional migration of silver ions and the deposition on the surface of the parts. Finally, it is suspended on the water control rack 4 for static water control, so that the plating layer of the parts reaches the best bonding strength, effectively reducing manual intervention and comprehensively improving production efficiency.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
