Description

Technical Field

[0001] This utility model relates to the technical field of VCP electroplating equipment, specifically a novel high-efficiency electroplating solution circulation filtration device for VCP electroplating equipment. Background Technology

[0002] VCP electroplating equipment is a device that electroplats workpieces using a vertical suspension method. It mainly consists of an electroplating tank, a transmission system, a power supply, and a control system. The electroplating solution circulation and filtration device is an indispensable part of VCP electroplating equipment. Its main function is to remove impurities from the electroplating solution, maintaining its cleanliness and uniformity, thereby ensuring electroplating quality and preventing plating defects. By removing impurities, the lifespan of the electroplating solution can be extended, production costs reduced, production efficiency improved, and production cycles shortened. The electroplating solution circulation and filtration device can also reduce harmful substances in the electroplating solution, improve the working environment, and protect the health of operators. It removes suspended solids, metal ions, and organic impurities from the electroplating solution and regulates its temperature, thus ensuring the stability and reliability of the electroplating process. The electroplating solution circulation and filtration device plays a crucial role in ensuring the quality, efficiency, and safety of VCP electroplating equipment.

[0003] Publication number CN221889331U discloses an electroplating solution circulating filtration device, comprising a cylindrical body with an internal receiving cavity and an inlet and an outlet on the side wall; an inlet pipe and an outlet pipe respectively pass through the inlet and outlet; a filter assembly is disposed in the receiving cavity, with its top end connected to the inlet pipe and its bottom end connected to the outlet pipe; the filter assembly is configured as at least one set, including: an upper connector, one end of which is connected to the inlet pipe; at least two filter elements, the inlet at the top of the first filter element being connected to the other end of each upper connector, and the filter elements being interconnected end to end; and a lower connector, one end of which is connected to the outlet at the bottom of the last filter element, and the other end of each lower connector being connected to the outlet pipe; this filtration device can perform multiple circulating filtration of the electroplating solution, effectively filtering out organic and metal contaminants in the electroplating solution.

[0004] The above technology utilizes the cylinder body and filter element to improve the filtration of electroplating solution. However, when using a partially filtered cylinder to filter the electroplating solution, the original electroplating solution cannot be guaranteed to have sufficient contact with the filtration equipment.

[0005] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed a new type of high-efficiency electroplating solution circulation filtration device for VCP electroplating equipment. Utility Model Content

[0006] The purpose of this invention is to provide a novel high-efficiency electroplating solution circulation filtration device for VCP electroplating equipment, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel high-efficiency electroplating solution circulation filtration device for VCP electroplating equipment, comprising: a tank body, an inner insert plate at the top of the tank body, a liquid infusion tube annularly inserted in the middle of the outer surface of the inner insert plate, a cap inserted at the upper end of the outer side of the liquid infusion tube, an inner filter chamber at the middle of the inner side of the liquid infusion tube, an overflow prevention cap at the upper end of the outer side of the inner filter chamber, a receiving ring on the outer side of the overflow prevention cap, and a liquid guide cap at the top of the receiving ring;

[0008] The bottom of the inner filter is provided with a bottom plate, and the interior of the inner filter is provided with an auxiliary structure.

[0009] Furthermore, the infusion tube has a multi-bend structure, which makes it easy for the outlet part at the bottom of the infusion tube to be attached to the inside of the tank, thus preventing splashing when the electroplating solution is discharged.

[0010] Furthermore, an annular cavity is provided in the middle of the inner side of the overflow cap. The end face of the middle part of the inner side of the overflow cap is higher than the end face of the outer part of the overflow cap, so that the middle part of the inner side of the overflow cap can fit together with the bottom of the liquid guide cover. When electroplating liquid overflows at the connection between the liquid guide cover and the middle part of the inner side of the overflow cap, the annular cavity of the overflow cap can store part of the overflowed electroplating liquid.

[0011] Furthermore, the area of ​​the cap is the same as the area of ​​the inner insert, and the geometric center of the cap and the geometric center of the inner insert are on the same straight line, which makes it easy for the cap and the inner insert to double clamp the outside of the infusion tube and prevent the infusion tube from shaking due to vibration or other reasons.

[0012] Furthermore, the auxiliary structure includes a coarse filter screen, a fine filter screen, a top recess, and a guide groove. A coarse filter screen is provided in the middle of the inner filter chamber, a fine filter screen is provided at the bottom of the coarse filter screen, and guide grooves are provided on both sides of the fine filter screen. A top recess is provided upward in the middle of the inner side of the bottom plate. The top recess has an inverted bowl-shaped structure, which facilitates the top recess forming an inclined path for the guide groove, providing potential energy for the discharge of the electroplating solution.

[0013] Furthermore, the spacing between the coarse filter screens is larger than that between the fine filter screens, which facilitates the filtration of the electroplating solution by the coarse and fine filter screens in a filtration sequence from coarse to fine.

[0014] Furthermore, the length of the guide groove is equal to the thickness of the inner filter, which facilitates the smooth introduction of the electroplating solution into the infusion pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model introduces electroplating liquid into the receiving ring from inside the liquid guide cap. At this time, the anti-overflow cap is placed in the middle of the inner side of the receiving ring. Since the port in the middle of the anti-overflow cap is constricted to the bottom of the liquid guide cap, if the electroplating liquid leaks when it is introduced into the bottom of the liquid guide cap, the annular gap of the anti-overflow cap can receive the electroplating liquid overflowing from the bottom of the liquid guide cap. At the same time, the cap and the inner insert fix the infusion tube, thus preventing the electroplating liquid from overflowing when it is introduced.

[0017] 2. This utility model uses an inner filter chamber to receive the electroplating solution introduced from the bottom of the anti-overflow cap. The coarse and fine filter screens inside the inner filter chamber filter the electroplating solution. At the same time, the guide groove guides the electroplating solution discharged from the fine filter screen into the infusion tube. The top recess groove restricts the overall height of the fine and coarse filter screens. In this way, the electroplating solution can be filtered twice by the coarse and fine filter screens. The filter grid gap of the fine filter screen is smaller than that of the copper filter screen. The guide groove, as the last discharge component, directly guides the liquid discharged from the fine filter screen into the infusion tube, thereby preventing insufficient filtration of the electroplating solution.

[0026] 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.

[0027] like Figures 1-7 As shown, a novel high-efficiency electroplating solution circulation filtration device for VCP electroplating equipment includes: a tank 4, an inner insert 8 at the top of the tank 4, a liquid delivery pipe 3 inserted in a ring at the middle of the outer surface of the inner insert 8, a cap 5 inserted at the upper end of the outer side of the liquid delivery pipe 3, an inner filter 6 at the middle of the inner side of the liquid delivery pipe 3, an overflow cap 7 at the upper end of the outer side of the inner filter 6, a receiving ring 2 on the outer side of the overflow cap 7, and a liquid guide cap 1 at the top of the receiving ring 2.

[0028] The bottom of the inner filter 6 is provided with a bottom plate 10, and the interior of the inner filter 6 is provided with an auxiliary structure 9.

[0029] As for the rest, when the liquid guide cap 1 introduces the electroplating solution into the receiving ring 2, the anti-overflow cap 7 first receives the liquid discharged from the bottom of the liquid guide cap 1. The inner layer of the anti-overflow cap 7 is provided with a semi-open cavity. At the same time, the inner part of the anti-overflow cap 7 is in contact with the bottom of the liquid guide cap 1. The area formed by the outer part of the anti-overflow cap 7 is larger than the area of ​​the bottom of the liquid guide cap 1. Therefore, the electroplating solution overflowing from the connection between the liquid guide cap 1 and the inner part of the anti-overflow cap 7 will flow into the cavity of the inner layer of the anti-overflow cap 7 along the outer side of the inner part of the anti-overflow cap 7, thereby preventing the electroplating solution from overflowing. Users can insert a connecting pipe with a structure similar to an infusion tube 3 in a ring on the surface of the outer part of the anti-overflow cap 7. These connecting pipes can be connected to the inner filter 6, so that the overflowing electroplating solution continues to enter the inner filter 6. The designer can also place the anti-overflow cap 7 on the top of the tank 4 to prevent the electroplating solution from overflowing a second time.

[0030] This has resulted in the following effects and novel technologies:

[0031] Regarding the design of the anti-overflow cap 7, the device has an anti-overflow cap 7 installed inside the receiving ring 2 to effectively prevent the electroplating solution from overflowing during the introduction process. Its inner semi-open cavity can receive the electroplating solution overflowing from the bottom of the liquid guide cover 1, while the annular slit design further receives the overflowing liquid, preventing it from flowing out of the tank 4. In terms of liquid guidance and circulation, the liquid guide cover 1 ensures that the electroplating solution is smoothly introduced into the receiving ring 2, while the connecting pipe on the outside of the anti-overflow cap 7 guides the overflowing electroplating solution back into the inner filter 6, achieving recycling. For fixation and stability, the double-fixing design of the cap 5 and the inner insert 8 prevents the infusion tube 3 from shaking, ensuring a stable infusion process. The infusion tube 3, with its multiple bends, reduces electroplating solution splashing. The cap 5 and the inner insert 8 share the same area and geometric center, facilitating precise fixation and improving overall stability. In terms of innovative technology, the semi-open cavity design of the anti-overflow cap 7, the cooperation between the liquid guide cap 1 and the anti-overflow cap 7, and the multiple bends of the infusion tube 3 are all innovations in existing technologies. These effectively solve the problem of electroplating solution overflow, improving the safety and reliability of the device. This device, through its unique design, enhances the circulation efficiency of the electroplating solution, reduces overflow and splashing, and strengthens the stability and safety of the equipment, which is of great significance for improving electroplating quality and production efficiency.

[0032] like Figures 1-7 As shown, a novel high-efficiency electroplating solution circulation filtration device for VCP electroplating equipment includes an auxiliary structure 9 comprising a coarse filter 91, a fine filter 92, a top groove 93, and a guide groove 94. The coarse filter 91 is located in the middle of the inner filter chamber 6, and the fine filter 92 is located at the bottom of the coarse filter 91. Guide grooves 94 are located on both sides of the fine filter 92. A top groove 93 is formed upwards in the middle of the inner side of the bottom plate 10, and the top groove 93 has an inverted bowl-shaped structure.

[0033] As for the rest, since the coarse filter 91 is located above the fine filter 92, when the inner filter chamber 6 receives the electroplating solution, the coarse filter 91 first filters the electroplating solution. The fine filter 92 is located at the bottom of the coarse filter 91, and the guide groove 94 is connected to both sides of the fine filter 92. Therefore, after the fine filter 92 performs a second filtration of the electroplating solution, the electroplating solution is directly introduced into the guide groove 94. Then, the guide groove 94 introduces the electroplating solution that has undergone secondary filtration into the interior of the infusion pipe 3. The designer can design multiple layers of coarse filter 91 or fine filter 92 to increase the filtration effect of the electroplating solution.

[0034] This has resulted in the following effects and novel technologies:

[0035] The auxiliary structure 9 achieves significant effects and novel technology. In terms of effect, the device achieves a double-layer filtration effect by setting up a coarse filter 91 and a fine filter 92. During the circulation process, the electroplating solution first undergoes preliminary filtration through the coarse filter 91, and then undergoes more refined filtration through the fine filter 92, effectively removing impurities and improving the cleanliness of the electroplating solution. The optimized filtration process ensures the sequential nature of the filtration, from coarse to fine, preventing insufficient filtration. The inverted bowl-shaped structure of the top groove 93 forms an inclined path for the guide groove 94, providing potential energy and facilitating liquid flow. In terms of novel technology… In terms of technology, the multi-layer filter design enhances the filtration effect. The inverted bowl-shaped top groove 93 provides an inclined path, and the cooperation between the guide groove 94, the coarse filter 91, and the fine filter 92 ensures that the electroplating solution is smoothly introduced into the infusion pipe 3, improving the efficiency and reliability of the filtration system. This device, through its unique double-layer filtration structure and optimized design, not only improves the filtration efficiency and cleanliness of the electroplating solution, reduces the impact of impurities, and enhances the electroplating quality and production efficiency, but also its novel design concept and technical features open up a new path for the development of electroplating solution circulation filtration devices.

[0036] Working Principle: When using the new high-efficiency electroplating solution circulation filtration device of this VCP electroplating equipment, firstly, the tank 4 is installed in a suitable position. Then, the electroplating solution is introduced into the receiving ring 2 through the liquid guide cover 1. An overflow cap 7 is set in the middle of the inside of the receiving ring 2. The cavity of the inner layer of the overflow cap 7 can store the electroplating liquid overflowing from the bottom connection of the liquid guide cover 1. The overflow cap 7 guides the electroplating liquid out of the bottom of the liquid guide cover 1 into the inner filter chamber 6. The cap 5 and the inner insert 8 firmly fix the overflow cap 7 to the outside of the inner filter chamber 6. The coarse filter screen 91 and the fine filter screen 92 inside the inner filter chamber 6 perform two filtration treatments on the electroplating solution. The guide groove 94 guides the electroplating solution filtered by the fine filter screen 92 into the inside of the infusion pipe 3. The infusion pipe 3 guides the treated electroplating solution into the inside of the tank 4. This is the working principle of the new high-efficiency electroplating solution circulation filtration device of this VCP electroplating equipment.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
