Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically a novel 3D swing device for electroplating tanks. Background Technology

[0002] Electroplating equipment technology encompasses the research, design, and application of equipment related to the electroplating process. Its core lies in the integration of mechanical, electrical, and electrochemical technologies to ensure the deposition of metallic coatings on metallic or non-metallic substrates. It includes power systems, electroplating tanks, auxiliary devices, and automated control systems, such as rectifier power supplies, corrosion-resistant tanks, and stirring and filtering equipment. These systems allow for precise control of parameters like current, temperature, and plating solution flow rate, adapting to different processes such as barrel plating and rack plating. They balance coating uniformity, density, and production efficiency, while also developing towards intelligent and green technologies to meet the stringent requirements of high-end manufacturing.

[0003] In the auxiliary device system of electroplating equipment technology, the novel electroplating tank oscillation device is a key piece of equipment for optimizing coating quality. It typically consists of a drive mechanism, oscillation support, vibration module, and controller. It drives the cathode or tank to oscillate back and forth via a motor, and with adjustable frequency vibration function, it enhances the circulation and mass transfer efficiency of the plating solution, quickly eliminates bubbles on the workpiece surface, and avoids defects such as pinholes and pitting. It is a typical example of the practical innovation of electroplating equipment technology.

[0004] However, in existing technologies, some electroplating equipment has design limitations in the displacement drive of the workpiece to be electroplated, and can only achieve unidirectional or reciprocating motion in a single dimension, such as forward / backward, left / right, or up / down, lacking a multi-dimensional synchronous linkage structure. This results in dead zones in the workpiece's movement in the plating solution, making it difficult for metal ions to diffuse evenly, and causing surface bubbles to easily adhere and remain, leading to defects such as uneven plating thickness, pinholes, and pitting, as well as insufficient plating density and adhesion.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0031] like Figures 1 to 4The illustration shows an embodiment of a novel 3D oscillating device for electroplating tanks provided by this utility model. It includes an electroplating tank 1, which serves as the core supporting substrate and is filled with electroplating liquid. Two mounting blocks 2 are fixedly connected to the top of the electroplating tank 1 to provide a stable assembly base for the fixed plate 3. The fixed plate 3 is fixedly connected to the inner wall of the two mounting blocks 2 to provide an mounting carrier for the anode plate 4. Multiple anode plates 4 are fixedly connected to the surface of the fixed plate 3, which can form a uniform electric field in the plating liquid to provide a stable electrochemical environment for the deposition of metal ions on the surface of the workpiece to be electroplated. They form an electrode pairing with the cathode plate 16 to meet the basic requirements of the oxidation-reduction reaction during the electroplating process. The multiple anode plates 4 are evenly distributed along the length of the fixed plate 3, and the height of the anode plates 4 is adapted to the liquid level of the plating liquid in the electroplating tank 1.

[0032] A drive assembly is fixedly connected to the right side of the electroplating tank 1 to provide power output for the movement of the device. The drive assembly includes a support block 5 for supporting and fixing a motor 6. The left side of the support block 5 is fixedly connected to the right side of the electroplating tank 1. The motor 6 is fixedly connected to the inner wall of the support block 5, which can drive the turntable 7 to rotate at a constant speed after starting. The drive end of the drive assembly is fixedly connected to the turntable 7 for mounting and fixing an eccentric shaft 8 and driving it to rotate synchronously. The bottom of the turntable 7 is fixedly connected to the drive end of the motor 6, and the top of the turntable 7 is fixedly connected to the eccentric shaft 8, forming an eccentric assembly with the turntable 7. During rotation, a periodic eccentric displacement is generated. The outer rotation of the eccentric shaft 8... A rotating sleeve 9 is connected to the rotating sleeve 9, which transmits the eccentric motion of the eccentric shaft 8 to the connecting plate 10. The inner wall of the rotating sleeve 9 is equipped with a rolling bearing, which greatly reduces the frictional resistance between the eccentric shaft 8 and the rotating sleeve 9, improves the transmission efficiency and the service life of the structure. The inner ring of the rolling bearing is interference-fitted with the outer ring of the eccentric shaft 8, and the outer ring is fixedly connected to the inner wall of the rotating sleeve 9. The connecting plate 10 is fixedly connected to the surface of the rotating sleeve 9, which receives the eccentric motion transmitted by the rotating sleeve 9 and converts it into the lateral driving force of the sliding plate 12. Two sliders 11 are rotatably connected to the inner wall of the connecting plate 10, which form a sliding fit with the groove on the surface of the sliding plate 12 to realize the conversion and transmission of the motion direction.

[0033] The inner wall of the connecting plate 10 is detachably connected to a sliding plate 12, which provides a mounting base for the cathode plate 16 and facilitates the disassembly and maintenance of the cathode plate 16. The slider 11 is externally slidably connected to a groove on the surface of the sliding plate 12. The front and rear sides of the sliding plate 12 are provided with slots 13, which form an elastic engagement with the plastic balls 15 on the inner wall of the capping block 14, realizing the detachable assembly of the sliding plate 12 and the capping block 14. The upper and lower sides of the sliding plate 12 are inserted into the capping block 14, providing a mounting base for the plastic balls 15. The inner wall of the capping block 14 is fixedly connected to two plastic balls 15 that engage with the slots 13. The elastic engagement simplifies the disassembly and assembly process of the cathode plate 16.

[0034] A cathode plate 16 is fixedly connected to the left side of the slide plate 12 for suspending the workpiece to be electroplated and driving it to move in multiple directions. The cathode plate 16 is triangular in shape, which optimizes the workpiece suspension density and can form multi-point rolling contact with the ball bearing 21 and the rotating roller 22 to drive itself to move up and down in the vertical direction. The surface of the cathode plate 16 is provided with multiple holes for suspending the workpiece to be electroplated, so as to achieve stable suspension and fixation of the workpiece to be electroplated. A sliding component is slidably connected to the bottom of the cathode plate 16 to provide guidance and support for the multi-directional movement of the cathode plate 16.

[0035] The sliding assembly includes two sliding plates 17 fixedly connected to the top of the electroplating tank 1, providing precise sliding guidance for the slide table 19. Limiting strips 18 are fixedly connected to both the front and rear sides of the sliding plates 17, effectively limiting the movement range of the slide table 19 and preventing deviation of the movement trajectory. The bottom of the limiting strips 18 is fixedly connected to the top of the electroplating tank 1. The slide table 19 is slidably connected to the surface of the sliding plates 17, providing a mounting base for the support plate 20. Two support plates 20 are fixedly connected to the top of the slide table 19, providing mounting support for the ball bearings 21 and the rotating roller 22. Two ball bearings 21 are movably connected to the inner wall of the support plate 20, forming rolling contact with the cathode plate 16, reducing motion friction while driving the cathode plate 16 to move in the vertical direction. The rotating roller 22 is also rotatably connected to the inner wall of the support plate 20, cooperating with the ball bearings 21 to form rolling contact with the cathode plate 16 to assist in driving the cathode plate 16 to move. The bottom of the cathode plate 16 is slidably connected to the surface of the two ball bearings 21 and the rotating roller 22, and the rolling contact synergy helps the cathode plate 16 to achieve three-axis synchronous 3D oscillation.

[0036] Working principle: The electroplating tank 1 serves as the core support substrate, and the two mounting blocks 2 provide a stable assembly base for the fixed plate 3. Multiple anode plates 4 mounted on the surface of the fixed plate 3 are evenly distributed along the length direction, which can form a uniform electric field in the plating solution, providing a stable electrochemical environment for the deposition of metal ions on the surface of the workpiece to be electroplated. This is the basic technical configuration of the electroplating process. Through the electrode pairing of the anode plate 4 and the cathode plate 16, the basic requirements of the oxidation-reduction reaction in the electroplating process are met.

[0037] The workpiece to be electroplated is suspended and fixed through multiple holes on the surface of the cathode plate 16. The cathode plate 16 adopts a triangular shape design, which optimizes the workpiece suspension density and provides structural adaptability for multi-directional movement. The slide plate 12 is elastically engaged with the plastic ball 15 on the inner wall of the top block 14 through the slots 13 on the front and rear sides. This detachable assembly structure facilitates the disassembly and maintenance of the cathode plate 16 and extends the service life of the cathode plate 16.

[0038] During operation, the motor 6, supported by the support block 5 on one side of the electroplating tank 1, starts, and its drive end drives the turntable 7 to rotate at a constant speed. The eccentric shaft 8 equipped on the turntable 7 rotates together. Due to the eccentric assembly design of the eccentric shaft 8 and the turntable 7, periodic eccentric displacement will be generated during its rotation. The interference fit between the rolling bearing on the inner wall of the rotating sleeve 9 and the eccentric shaft 8 can greatly reduce the frictional resistance between the eccentric shaft 8 and the rotating sleeve 9, improve the transmission efficiency and structural service life, and the rotating sleeve 9 in turn drives the assembled connecting plate 10 to perform eccentric movement synchronously. The two sliders 11 on the inner wall of the connecting plate 10 are embedded in the grooves on the surface of the slide plate 12 to form a sliding fit, which converts the eccentric movement of the connecting plate 10 into the lateral driving force of the slide plate 12, driving the cathode plate 16 to reciprocate in the horizontal direction.

[0039] Meanwhile, the triangular shape of the cathode plate 16 causes its contact area to form multi-point rolling contact with the balls 21 and rotating rollers 22 on the inner wall of the support plate 20 in the sliding assembly. During horizontal movement, the rolling friction generated by the inclined surface of the triangular shape and the balls 21 and rotating rollers 22 will drive the cathode plate 16 to move up and down in the vertical direction. The eccentricity of the eccentric shaft 8, when driving the connecting plate 10 to move, will also cause the cathode plate 16 to generate additional front-to-back auxiliary displacement in the horizontal direction through the sliding compensation of the slider 11 and the sliding plate 12, ultimately realizing the three-axis synchronous 3D oscillation of the cathode plate 16 and the suspended workpiece.

[0040] During this process, the sliding plate 17 equipped in the electroplating tank 1 provides precise sliding guidance for the sliding table 19, and the support plate 20 equipped in the sliding table 19 provides installation support for the ball bearing 21 and the rotating roller 22. The limiting strips 18 on both sides of the sliding plate 17 can effectively limit the movement range of the sliding table 19, avoid deviation of the movement trajectory, and ensure that the swinging movement of the cathode plate 16 is precise and controllable. The synergistic effect of each structure enables the workpiece to be electroplated to achieve dynamic movement in the plating solution in all directions without dead angles, maximizes the uniform diffusion of metal ions, reduces the adhesion of bubbles on the surface of the workpiece, and, combined with the uniform electric field formed by the anode plate 4, significantly improves the uniformity, density and adhesion of the coating.
