Description

Technical Field

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

[0002] Although electroplating additives are added in a low proportion to the electroplating solution, they play a decisive role in the quality of electroplated products. They can effectively improve the gloss, smoothness, adhesion and corrosion resistance of the electroplated layer, and also optimize the current efficiency and deposition rate during the electroplating process, and reduce coating defects (such as pinholes, pitting, scorching, etc.). Therefore, electroplating additive feeding devices are indispensable equipment to ensure the stable implementation of the electroplating process and achieve high-quality electroplating production.

[0003] However, traditional electroplating additive feeding methods mostly rely on manual addition or simple mechanical feeding, which have problems such as low feeding accuracy, poor sealing, easy leakage, and inability to control in real time. At the same time, the additives may contain undissolved particles or impurities, and direct addition can easily lead to plating solution contamination or poor plating. In addition, feeding and stirring are often carried out separately, which is not only cumbersome and inefficient, but also easily causes excessively high local concentrations or uneven dispersion of additives, affecting the consistency of electroplating quality, increasing production costs and control difficulties. To address these issues, we propose an electroplating additive feeding device. Utility Model Content

[0050] Discharge pipe 9: Discharge pipe 9 is the output channel of the additive. It is a tubular structure, fixed on the same plane as the connecting plate 7 and perpendicular to the feed pipe 8. It is also coaxially fixed with the feed hole of the processing tank 1.

It connects the feed pipe 8 and the processing tank 1 to ensure that the additive enters the mixing and filtration stage stably after the amount is controlled. It is the key output section of the additive conveying path.

[0051] Filter cartridge 10: Filter cartridge 10 is the filter and stirring component for the additive. It has a cylindrical structure with dense filter holes on the bottom and arc surfaces. The bottom is fixedly connected to the shaft 11 and rotatably connected to the connection hole of the treatment tank 1. It is placed coaxially inside the treatment tank 1.

[0052] Connecting shaft 11: Connecting shaft 11 is a rotating connecting component of filter cartridge 10. It is a shaft-shaped structure. One end is fixed to the middle of the bottom surface of filter cartridge 10, and the other end is rotatably connected to the connecting hole of processing tank 1. It is also coaxially fixed to one end of rotating component 5. It transmits the rotational power of rotating component 5 to filter cartridge 10, causing filter cartridge 10 to rotate stably.

[0055] Rubber ring 14: Rubber ring 14 is a sealing component. It has a ring structure and is coaxially fixed in the stepped hole of the connecting plate 7. The inner ring contacts the outer ring of the plug rod 16. It fills the gap between the plug rod 16 and the stepped hole, enhances the sealing performance of the two, prevents the additive from leaking from the gap during the sliding of the plug rod 16, avoids raw material loss and contamination, ensures the sealing performance of the additive delivery during the quantity control process, and improves the quantity control accuracy of the device.

[0056] Lead screw 15: Lead screw 15 is the power transmission and linear drive component of the control assembly. It is a threaded shaft structure. One end is threaded to the threaded hole of the sliding cylinder of the large gear 12, and the other end is fixed to the connecting plate of the plug rod 16. It converts the rotational motion of the large gear 12 into its own linear motion, pushes the plug rod 16 to slide along the guide rod 18, and thus adjusts the gap between the plug rod 16 and the flow hole of the partition plate 17. It is the core component in the control mechanism to realize power conversion and plug rod drive.

[0057] Plug rod 16: Plug rod 16 is the actuator for controlling the amount of additive. It is a rod-shaped structure with one end pointed and the other end fixed to a connecting plate. The connecting plate is fixed to the lead screw 15 and has a hole for the guide rod 18 to slide through. It is slidably connected to the stepped hole of the connecting plate 7. Its pointed end corresponds to the flow hole of the partition plate 17. By sliding along the guide rod 18, the gap with the flow hole is changed to adjust the additive flow rate. At the same time, it is sealed with the rubber ring 14. It is a key component for directly controlling the additive flow rate.

[0058] Separator 17: Separator 17 is an auxiliary structure for controlling the flow of additives. It is a sheet-like structure fixed at the intersection of the feed pipe 8 and the discharge pipe 9. It has flow holes on its plane, which guide the additive in the feed pipe 8 to the flow holes, so that the additive can only flow to the discharge pipe 9 through the flow holes. It works with the pointed end of the plug rod 16 to adjust the opening of the flow holes, providing a precise flow control point for quantity control and ensuring the stability and accuracy of additive flow regulation.

[0059] Guide rod 18: Guide rod 18 is a sliding guide component of plug rod 16. It is a shaft-shaped structure and is fixed on the inner wall of the outer shell 6 opposite to the mounting wall of the transmission component. It is slidably connected to the sliding hole of the connecting plate of plug rod 16. It restricts the movement direction of plug rod 16, ensuring that plug rod 16 can only slide in a straight line, avoiding the plug rod 16 from deviating during the sliding process, ensuring that the tip of plug rod 16 is always precisely aligned with the flow hole of partition plate 17, and improving the stability and accuracy of the control mechanism adjustment.

[0060] Working principle: When the electroplating additive feeding device is started, the motor 2, as the power source, synchronously drives the control mechanism and the stirring transmission assembly to operate: the output shaft of the motor 2 drives the small gear 13 inside the housing 6 to rotate, and the large gear 12 meshing with the small gear 13 rotates accordingly. Since the sliding cylinder fixed on the plane of the large gear 12 is threadedly connected to the lead screw 15, the rotational motion of the large gear 12 is converted into the linear motion of the lead screw 15; the lead screw 15 pushes the plug rod 16 fixed thereto to slide precisely along the guide rod 18. At this time, the plug rod 16 moves in the stepped hole of the connecting plate 7. The rubber ring 14 in the stepped hole tightly fits the outer ring of the plug rod 16 to ensure that the additive does not leak from the gap; the pointed end of the plug rod 16 corresponds to the flow hole of the partition plate 17 in the feed pipe 8. By adjusting the gap between the two, the flow rate of the additive flowing into the feed pipe 8 can be flexibly controlled to achieve precise quantity control and avoid waste of raw materials and imbalance of electroplating solution composition.

[0061] Simultaneously, motor 2 drives connecting rod 3 on the hinge plate of processing tank 1 to swing around the hinge point. The spherical sleeve at the other end of connecting rod 3 flexibly rotates and cooperates with the rotating ball at one end of connecting rod 4, transmitting power to connecting rod 4. Connecting rod 4 drives the rotating component 5 connected to it to rotate. One end of the rotating component 5 is coaxially fixed with the connecting shaft 11 of filter cylinder 10, thereby driving the connecting shaft 11 and filter cylinder 10 to rotate coaxially inside processing tank 1. The additive, after being controlled and adjusted, flows from the feed pipe 8 through the discharge pipe 9 and enters the interior of processing tank 1 through the feed hole of processing tank 1. It first contacts the rotating filter cylinder 10. The dense filter holes on the bottom surface and arc surface of filter cylinder 10 filter out undissolved particles and impurities in the additive, preventing impurities from contaminating the electroplating solution. At the same time, the rotation of filter cylinder 10 stirs the electroplating solution in processing tank 1, allowing the filtered additive to quickly and evenly blend with the electroplating solution, preventing the local concentration of the additive from being too high or the dispersion from being uneven, and ensuring the stability of the electroplating reaction.

[0062] Throughout the process, the connecting plate 7 serves as a transition structure, ensuring precise docking of the inlet pipe 8, outlet pipe 9, outer shell 6, and processing tank 1, maintaining the smooth flow path of the additives; the guide rod 18 restricts the movement direction of the blocking rod 16, ensuring that the blocking rod 16 and the flow hole of the partition plate 17 always correspond precisely, further improving the control accuracy; the outer shell 6 provides protection and installation support for the transmission components of the control mechanism, preventing external impurities from interfering with the gear transmission and ensuring the stable operation of the control mechanism.

[0063] Ultimately, through the coordinated operation of various structures, the device achieves integrated operation of precise additive dosage control, impurity filtration, and uniform stirring, effectively solving the problems of low precision, cumbersome process, and unstable coating quality in traditional feeding methods. This ensures stable electroplating product quality, improves electroplating efficiency, and reduces production costs and operational difficulty.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
