Description

Technical Field

[0001] This utility model relates to the technical field of pattern electroplating equipment, specifically a pattern electroplating copper tank filtration device. Background Technology

[0002] Pattern electroplating is an electroplating process in the field of pattern electroplating equipment technology that targets specific pattern areas. It mainly involves controlling the electroplating range to deposit metal (such as copper) on a preset pattern area on the surface of the workpiece to meet the precise requirements of electronic components and other products for conductivity and structural morphology.

[0003] Electroplating filters are key equipment in graphic electroplating systems, primarily used for filtering electroplating solutions. They typically include components such as a support frame, pump, inlet pipe, thick-plate tank, filter cartridge assembly, and outlet. The pump delivers the electroplating solution, while the filter cartridge assembly removes impurities, ensuring the cleanliness of the solution and thus improving electroplating quality.

[0004] In existing technologies, the upper cover limiting and locking of electroplating filter machines mostly rely on an upper ring assembly composed of multiple swingable threaded structures. When the filter element assembly becomes clogged due to long-term use and needs to be replaced, the operator must first operate multiple threaded structures to release the upper cover's limiting position, remove the upper cover to replace the filter element, and then operate multiple threaded structures again to re-lock the upper cover. This results in numerous operating parts and cumbersome steps, making the filter element replacement process time-consuming and labor-intensive. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a patterned copper plating tank filtration device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a graphic electroplating copper tank filter device, comprising a support and a thick plate barrel, wherein a limiting frame is fixed on the surface of the thick plate barrel, a top cover is connected to the top of the thick plate barrel, and a limiting cover is sleeved on the outside of the top cover, a first hoop is connected between the limiting cover and the limiting frame, and a second hoop is connected to both sides of the outer surface of the first hoop, and a locking bolt is connected between the two ends of the first hoop.

[0007] By adopting the above technical solution, a new type of upper cover limiting and locking structure is constructed through the coordinated cooperation of the limiting frame, limiting cover, first hoop, second hoop and locking bolt. This replaces the traditional upper ring assembly composed of multiple swingable threaded structures, reduces the number of operating parts, and provides a convenient basis for the replacement of the filter element assembly.

[0008] Furthermore, the longitudinal section of the limiting frame is "C" shaped, and the bottom of the limiting cover is provided with a protrusion with a longitudinal section of "L".

[0009] By adopting the above technical solution, the C-shaped longitudinal section of the limiting frame and the L-shaped protrusion at the bottom of the limiting cover can form a groove structure that works together, providing a stable installation space for the first hoop and the second hoop, making it easy for the hoop to tightly hug the two to achieve limiting, and improving the positioning stability between the top cover and the thick plate barrel.

[0010] Furthermore, the bottom protrusions of the limiting frame and the limiting cover are provided with multiple protrusions, and the multiple bottom protrusions of the limiting frame and the limiting cover are distributed in a ring array.

[0011] By adopting the above technical solution, the annular array distribution of multiple limiting frames and bottom protrusions of the limiting cover can make each component uniformly stressed in the circumferential direction, and at the same time provide a structural basis for the bottom protrusions of the limiting cover to pass through the gaps of the limiting frames, which facilitates the initial alignment when the top cover is placed.

[0012] Furthermore, the cross-section of the bottom protrusions of the limiting frame and the limiting cover is arc-shaped, and the multiple limiting frames and the multiple bottom protrusions of the limiting cover are distributed alternately.

[0013] By adopting the above technical solution, the arc-shaped design of the cross section allows the bottom protrusion of the limiting frame and the limiting cover to better fit the ring structure, while the staggered distribution allows the two to be spliced ​​together to form a complete ring, enhancing the overall structure, reducing the possibility of rotation after the top cover is installed, and improving the positioning accuracy.

[0014] Furthermore, the top cover is detachably connected to the thick plate barrel, and the first hoop is detachably connected to the limiting frame and the bottom protrusion of the limiting cover by locking bolts.

[0015] By adopting the above technical solution, the disassembly and connection between the top cover and the thick plate barrel facilitates the removal of the top cover, and the disassembly and connection of the first hoop through the locking bolts facilitates the disassembly and assembly of the hoop. The combination of the two provides operational convenience for the replacement of the filter element group and reduces the time consumption during the maintenance process.

[0016] Furthermore, both the first hoop and the second hoop have arc-shaped cross-sections, and the longitudinal section of the first hoop is an isosceles trapezoid.

[0017] By adopting the above technical solution, the arc-shaped cross-sections of the first hoop and the second hoop can be adapted to the ring-shaped limiting frame and the limiting cover, which facilitates a tight embrace; the isosceles trapezoidal structure of the longitudinal section of the first hoop can guide the hoop into the groove during assembly, and at the same time can apply a downward axial force to the limiting cover, thereby improving the tightness of the fit between the top cover and the thick plate barrel.

[0018] Furthermore, the two ends of the second hoop are fixedly connected to the two sides of the outer surface of the first hoop by welding or installing rivets, and the two sides and back of the first hoop are in contact with the second hoop.

[0019] By adopting the above technical solution, the fixed connection at both ends of the second hoop ensures that it can bend synchronously with the first hoop, while the contact state of the remaining areas reduces the bending resistance of the double hoop structure. This not only increases the overall wall thickness to enhance the ability to withstand axial forces, but also reduces the operational difficulty during assembly.

[0020] Furthermore, a liquid pump is installed inside the support, and the inlet end of the liquid pump is connected to an inlet pipe. The outlet end of the liquid pump is connected to a thick plate barrel connected to the top of the support. Multiple filter cartridges are connected inside the thick plate barrel. An outlet is connected to the bottom of the thick plate barrel. An exhaust valve assembly and a pressure gauge are installed on one side of the thick plate barrel. A dosing tank is connected to the top side of the support, and the bottom end of the exhaust valve assembly extends into the dosing tank. A dosing valve assembly is connected between the dosing tank and the inlet pipe.

[0021] By adopting the above technical solution, components such as the liquid pump, inlet pipe, and filter cartridge work together to achieve the delivery, filtration, and impurity removal of the electroplating solution; the dosing tank and dosing valve group work together to replenish the solution, while the exhaust valve group and pressure gauge realize gas discharge and pressure monitoring respectively, jointly ensuring the stable operation of the filtration system and improving the cleanliness of the electroplating solution.

[0022] Furthermore, both the first and second hoop rings are made of 316 stainless steel.

[0023] By adopting the above technical solution, the properties of 316 stainless steel material improve the structural strength, corrosion resistance and fatigue resistance of the first and second hoop rings, reduce damage caused by repeated bending and disassembly, and extend the service life of the hoop ring structure.

[0024] Furthermore, the limiting cover and the upper cover are connected by bolts, and the limiting cover is detachably connected to the upper cover by bolts.

[0025] By adopting the above technical solution, the bolt connection between the limiting cover and the upper cover enables their detachable assembly. When the L-shaped protrusion at the bottom of the limiting cover breaks or is damaged, the limiting cover can be disassembled and replaced separately, reducing the cost of replacing the entire component and improving the convenience of maintenance.

[0026] In summary, the present invention has the following main advantages: 1. This utility model, through the setting of a limiting frame, a limiting cover, and a first hoop, with the bottom protrusions of the limiting frame and the limiting cover being staggered and forming a complete circle, can achieve the initial positioning of the top cover and prevent the top cover from rotating subsequently; at the same time, the isosceles trapezoidal design of the longitudinal section of the first hoop, the inclined surface of the trapezoid can facilitate the guide into the groove of the limiting frame and the limiting cover during the assembly process, and can also apply a downward axial force to the limiting cover, improving the tightness of the fit between the top cover and the thick plate barrel, and reducing the situation of poor sealing effect of the sealing ring due to loose connection; 2. By setting locking bolts, this utility model can achieve the circumferential positioning of the limiting frame and the limiting cover by locking the two ends of the first hoop with only a small number of locking bolts, which replaces the multiple swingable threaded structures in the prior art, reduces the number of operating parts and steps in the filter element replacement process, and reduces the time consumption and labor costs of operation. 3. By setting a second hoop, the second hoop is fixed to the first hoop only at both ends, while the rest of the area only contacts the first hoop. On the one hand, this increases the overall wall thickness of the hoop, improves the ability to withstand axial forces, and reduces the problem of the upper cover failing due to deformation under force. On the other hand, the middle area of ​​the contact surface between the first hoop and the second hoop has a layered characteristic, which makes it easier to bend than a single-layer hoop with a large thickness, reducing the difficulty of bending operations during assembly.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1: A patterned copper plating tank filter device, such as Figures 1-5As shown, the device includes a support 1 and a thick plate barrel 4. Its features include: a limiting frame 11 fixed to the surface of the thick plate barrel 4, the limiting frame 11 having a "C"-shaped longitudinal section; a top cover 12 connected to the top of the thick plate barrel 4, the top cover 12 being detachably connected to the thick plate barrel 4; a limiting cover 13 sleeved on the outside of the top cover 12; a protrusion with an "L"-shaped longitudinal section at the bottom of the limiting cover 13; multiple protrusions at the bottom of both the limiting frame 11 and the limiting cover 13; the multiple bottom protrusions of the limiting frame 11 and the limiting cover 13 being arranged in a circular array; the cross-section of the bottom protrusions of the limiting frame 11 and the limiting cover 13 being arc-shaped; and the multiple bottom protrusions of the limiting frame 11 and the multiple bottom protrusions of the limiting cover 13 being staggered. The worker places the top cover 12 with the limiting cover 13 on top of the thick plate barrel 4. At this time, the L-shaped protrusions of the bottom of the limiting cover 13, which are arranged in a circular array, will pass through the gaps between the limiting frames 11, which are also arranged in a circular array. Since the cross-sections of the two are arc-shaped and staggered, they together form a complete circle, achieving the initial positioning of the top cover 12 and preventing the top cover 12 from rotating. A first hoop 14 is connected between the limiting cover 13 and the limiting frame 11. The longitudinal section of the first hoop 14 is an isosceles trapezoid. The two sides of the outer surface of the first hoop 14 are connected to the second hoop 15. The cross-sections of the first hoop 14 and the second hoop 15 are both arc-shaped. The two ends of the second hoop 15 The first hoop 14 is fixedly connected to both sides of its outer surface by welding or riveting. The sides and back of the first hoop 14 are in contact with the second hoop 15. Locking bolts 16 are connected between the two ends of the first hoop 14. The first hoop 14 is detached and connected to the bottom protrusion of the limiting frame 11 and the limiting cover 13 by the locking bolts 16. After the worker opens the first hoop 14 and the second hoop 15 into a semi-circular arc shape, they are placed in the groove of the C-shaped limiting frame 11 and the groove of the L-shaped protrusion at the bottom of the limiting cover 13. After the worker stops applying force to open the first hoop 14 and the second hoop 15, the first hoop 14 and the second hoop 15 will then return to their original nearly complete circles by themselves. Finally, the workers install two locking bolts 16 at the contact areas of the two ends of the first hoop 14. During the tightening of the locking bolts 16, the first hoop 14 will deform and its diameter will become smaller, and the two ends will close into a complete circle. Due to the isosceles trapezoidal structure of the longitudinal section of the first hoop 14, the inclined surfaces at the top and bottom are easy to guide the first hoop 14 into the groove of the C-shaped limit frame 11 and the groove of the L-shaped protrusion at the bottom of the limit cover 13 during assembly. The inclined surfaces can apply a downward axial force to the limit cover 13, improve the tightness of the fit between the upper cover 12 and the thick plate barrel 4, and reduce the situation where the sealing ring of the upper cover 12 is not sealed well due to the loose connection of the upper cover 12.After the locking bolt 16 is tightened, the first hoop 14 will encircle the bottom protrusion of the limiting frame 11 and the limiting cover 13. The limiting frame 11 abuts against the first hoop 14 to reduce its vertical axial displacement, while the first hoop 14 abuts against the bottom protrusion of the limiting cover 13 to reduce the possibility of the upper cover 12 and the limiting cover 13 falling upward. In addition, the double hoop structure of the first hoop 14 and the second hoop 15 increases the overall wall thickness, improves the ability to withstand axial forces, and reduces the problem of the upper cover 12 failing to limit due to deformation under force.

[0032] See Figure 1 and Figure 2 In the above embodiment, a liquid pump 2 is installed inside the support 1. The inlet end of the liquid pump 2 is connected to an inlet pipe 3, and the outlet end of the liquid pump 2 is connected to a thick plate barrel 4 connected to the top of the support 1. Multiple filter element groups 10 are connected inside the thick plate barrel 4, and an outlet 5 is connected to the bottom of the thick plate barrel 4. An exhaust valve group 6 and a pressure gauge 9 are respectively installed on one side of the thick plate barrel 4. A dosing tank 7 is connected to the top side of the support 1. The bottom end of the exhaust valve group 6 extends into the dosing tank 7. A dosing valve is connected between the dosing tank 7 and the inlet pipe 3. The chemical valve assembly 8 and the entire device are stably supported by the bracket 1. The liquid pump 2 delivers the electroplating solution to the thick plate tank 4 through the liquid inlet pipe 3. The filter element assembly 10 in the thick plate tank 4 filters the electroplating solution to remove impurities. The filtered electroplating solution is discharged through the liquid outlet 5. The pressure gauge 9 is used to monitor the pressure in the thick plate tank 4 to ensure the stable operation of the filtration process. During maintenance, the chemical dosing tank 7 adds chemicals to the liquid inlet pipe 3 through the chemical dosing valve assembly 8, and the exhaust valve assembly 6 can discharge the gas in the thick plate tank 4 into the chemical dosing tank 7.

[0033] Example 2: Based on the above embodiment 1, in order to extend the service life of the first hoop ring 14 and the second hoop ring 15, the following settings are now implemented.

[0034] See Figure 1 , Figure 3 , Figure 4 and Figure 5 In the above embodiments, both the first hoop 14 and the second hoop 15 are made of 316 stainless steel. The use of 316 stainless steel in the first hoop 14 and the second hoop 15 makes them more durable and reduces damage during repeated bending and disassembly.

[0035] Example 3: Based on the above embodiment 1, the following settings are made to facilitate the replacement of the limiting cover 13.

[0036] See Figure 1 , Figure 3 and Figure 5In the above embodiment, the limiting cover 13 and the upper cover 12 are connected by bolts. The limiting cover 13 is detachably connected to the upper cover 12 by bolts. When the L-shaped protrusion at the bottom of the limiting cover 13 is broken or damaged, the limiting cover 13 can be removed and replaced by removing the bolts, which improves the convenience of component replacement.

[0037] The implementation principle of this utility model is as follows: First, the entire device is stably supported by the bracket 1. The liquid pump 2 delivers the electroplating solution to the thick plate tank 4 through the liquid inlet pipe 3. The filter element group 10 in the thick plate tank 4 filters the electroplating solution to remove impurities. The filtered electroplating solution is discharged through the liquid outlet 5. The pressure gauge 9 is used to monitor the pressure in the thick plate tank 4 to ensure the stable operation of the filtration process. During maintenance, the chemical dosing tank 7 adds chemicals to the liquid inlet pipe 3 through the chemical dosing valve group 8, and the exhaust valve group 6 can discharge the gas in the thick plate tank 4 into the chemical dosing tank 7. When the pressure inside the thick plate barrel 4 is high, it indicates that the filter element assembly 10 is clogged. When replacing the filter element assembly 10, the staff first loosens the locking bolt 16, then opens the first hoop 14 and the second hoop 15 into a semi-circular arc and removes them. Then the staff can remove the top cover 12 and the limit cover 13 from the top of the thick plate barrel 4, and then the filter element assembly 10 can be inspected and replaced. After the filter cartridge 10 is replaced, when it is time to install the top cover 12, the worker places the top cover 12 with the limiting cover 13 on top of the thick plate barrel 4. At this time, the L-shaped protrusions arranged in a circular array at the bottom of the limiting cover 13 will pass through the gaps between the limiting frames 11, which are also arranged in a circular array. Since both of them have arc-shaped cross-sections and are staggered, they together form a complete circle, achieving the initial positioning of the top cover 12 and preventing the possibility of the top cover 12 rotating. Subsequently, the worker opens the first hoop 14 and the second hoop 15 into a semi-circular arc and places them in the grooves of the C-shaped limiting frame 11 and the grooves of the L-shaped protrusions at the bottom of the limiting cover 13. The worker stops applying force to open the first hoop 14 and the second hoop 15, and then the first hoop 14 and the second hoop 15 return to their original nearly complete circular arcs by themselves. Finally, the worker installs two locking bolts 16 at the contact areas at both ends of the first hoop 14. During the tightening of the locking bolts 16, the first hoop 14 will deform and its diameter will change. The size decreases, and both ends close to form a complete circle. Due to the isosceles trapezoidal structure of the longitudinal section of the first hoop 14, the inclined surfaces at its top and bottom facilitate guidance during assembly, allowing the first hoop 14 to enter the groove of the C-shaped limiting frame 11 and the L-shaped protrusion at the bottom of the limiting cover 13. Furthermore, the inclined surfaces can apply a downward axial force to the limiting cover 13, improving the tightness of the fit between the upper cover 12 and the thick plate barrel 4, reducing the possibility of poor sealing effect of the sealing ring of the upper cover 12 due to loose connection. The lock... After the bolt 16 is tightened, the first hoop 14 will surround the bottom protrusion of the limiting frame 11 and the limiting cover 13. The limiting frame 11 abuts against the first hoop 14 to reduce its vertical axial displacement. The first hoop 14 abuts against the bottom protrusion of the limiting cover 13 to reduce the possibility of the upper cover 12 and the limiting cover 13 falling off upwards. In addition, the double hoop structure of the first hoop 14 and the second hoop 15 increases the overall wall thickness, improves the ability to withstand axial force, and reduces the problem of the upper cover 12 failing to limit due to deformation under force. The second hoop 15, which mates with the first hoop 14, is fixed to the outer surfaces of the first hoop 14 only at both ends by welding or riveting. The remaining area of ​​the second hoop 15 facing the first hoop 14 is only in contact with the first hoop 14. When the first hoop 14 is bent under force, it will cause the second hoop 15 to bend synchronously. Since the middle area of ​​the contact surface between the first hoop 14 and the second hoop 15 is only in contact and not rigidly connected, the contact surface between the first hoop 14 and the second hoop 15 can have a layered effect. Compared with a single-layer hoop of the same thickness after the first hoop 14 and the second hoop 15 are stacked, it is easier to bend and reduces the difficulty of assembly.
