Description

Technical Field

[0001] This application relates to the field of electroplating equipment, and in particular to an integrated equipment for circulating and purifying electroplating bath solutions. Background Technology

[0002] Electroplating bath solution is a chemical solution used in the electroplating process to deposit a metal coating on the surface of a workpiece. Its core function is to reduce metal ions through electrolysis and deposit them onto the workpiece surface, which serves as the cathode, to form a uniform and dense metal coating. In order to improve the utilization rate of electroplating bath solution, it is usually purified and recycled.

[0003] The recycling of electroplating solution requires multiple filtrations of the used solution before it can be reused. During the filtration process, the temperature needs to be controlled to avoid crystallization or reaction imbalance caused by temperature differences. Existing circulating purification equipment usually controls the temperature by setting up an external temperature control device during filtration. It takes a certain amount of time for the temperature to be transmitted to the center of the electroplating solution. During this time, the temperature difference can easily cause crystallization or reaction imbalance in the center of the electroplating solution. Summary of the Invention

[0004] To improve temperature control, this application provides an integrated device for circulating and purifying electroplating bath solution.

This allows the filter screen to exchange heat with the center of the electroplating bath while filtering, so that the temperature control effect is directly applied to the center of the electroplating bath, reducing the probability of excessive temperature difference between the center and the edge of the electroplating bath and improving the temperature control effect.

[0007] Preferably, the filter screen includes a connecting pipe and a screen part, the connecting pipe is fixed to the filter cylinder and connected to the temperature control pipe, and the screen part is detachably installed on the connecting pipe.

[0008] By adopting the above technical solution, the connecting pipe is fixed to the filter cylinder, and the mesh part with different filter pore sizes can be replaced by disassembling the mesh part, so that the filter cylinder can be used for different requirements in multi-stage filtration of electroplating bath liquid.

[0009] Preferably, the connecting pipe has a groove, and the mesh body has a fixed insert, which is embedded in the groove.

The driving rod drives the linkage rod to slide towards the push rod, the linkage rod drives the push rod to slide towards the fixed insert, and the push rod drives the fixed insert to slide and be inserted into the fixed slot.

[0014] By adopting the above technical solution, the driving component can drive the fixed insert block to be inserted into the fixed slot when the insert block abuts against the bottom of the slot, thereby facilitating the driving of the fixed component.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0034] This application discloses an integrated electroplating tank solution circulation and purification device, referring to... Figure 1 , Figure 2 and Figure 3The system includes multiple filter cartridges 1, each equipped with an inlet pipe 2 and an outlet pipe 3. Each filter cartridge 1 is connected to an adjacent outlet pipe 3 via the inlet pipe 2. Each filter cartridge contains a filter screen 5, which separates the inlet pipe 2 from the outlet pipe 3. The inlet pipe 2 connects to the filter cartridge 1 above the filter screen 5, and the outlet pipe 3 connects to the filter cartridge 1 below the filter screen 5. A temperature control pipe 4 surrounds the filter cartridge 1, connecting to a temperature control device. The temperature control device allows high-temperature gas or low-temperature gas to be introduced into the temperature control pipe 4. The liquid allows the high-temperature gas or low-temperature liquid in the temperature control pipe 4 to exchange heat with the electroplating bath liquid in the filter cartridge 1, thereby controlling the temperature. The filter screen body 5 is hollow, and the temperature control pipe 4 connects to the inside of the filter screen body 5. By making the filter screen hollow and connecting the temperature control pipe 4 to the inside of the filter screen, the filter screen can exchange heat with the center of the electroplating bath liquid while filtering. This allows the temperature control effect to directly act on the center of the electroplating bath liquid, reducing the probability of excessive temperature difference between the center and the edge of the electroplating bath liquid and improving the temperature control effect.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The filter body 5 includes a connecting pipe 51 and a mesh part 52. The connecting pipe 51 is fixed to the filter cylinder 1 and connected to the temperature control pipe 4. The mesh part 52 is detachably installed on the connecting pipe 51. The connecting pipe 51 is fixed to the filter cylinder 1. By disassembling the mesh part 52, mesh parts 52 with different pore sizes can be replaced, so that the filter cylinder 1 can be used for filtration of different requirements in multi-stage filtration of electroplating bath liquid. A groove 6 is provided on the connecting pipe 51, and an insert 7 is fixed on the mesh part 52. The insert 7 is embedded in the groove 6. Inside, the groove 6, together with the insert 7, facilitates the docking and installation of the net body 52 on the connecting pipe 51; a fixing component 8 is provided between the insert 7 and the groove 6, the fixing component 8 includes a fixing slot 81 and a fixing plug 82, the fixing slot 81 is opened on the insert 7, and the fixing plug 82 is slidably disposed on the connecting pipe 51. When the insert 7 is embedded in the groove 6, the fixing plug 82 is inserted into the fixing slot 81. The fixing component 8 can fix the docked net body 52 on the connecting pipe 51.

[0036] Reference Figure 2 , Figure 3 and Figure 4A driving component 9 is provided on the connecting pipe 51. The driving component 9 includes a driving rod 91, a linkage rod 92, a push rod 93, and a driving spring 94. The driving rod 91 is slidably disposed at the bottom of the groove 6. The linkage rod 92 is slidably disposed inside the connecting pipe 51 and abuts against the driving rod 91. The end of the driving rod 91 that abuts against the linkage rod 92 has a chamfer. The push rod 93 is slidably disposed inside the connecting pipe. One end of the push rod 93 abuts against the end of the linkage rod 92 away from the driving rod 91, and the other end of the push rod 93 that abuts against the fixed insert 82. Both ends of the push rod 93 that abut against the linkage rod 92 and the fixed insert 82 have chamfers. A moving spring 94 is disposed between the connecting tube 51 and the drive plug. The elastic force of the drive spring 94 drives the fixed plug 82 to slide away from the fixed slot 81. The insert 7 is embedded in the groove 6, which drives the drive rod 91 to slide and be stored in the connecting tube 51. The drive rod 91 drives the linkage rod 92 to slide towards the top rod 93. The linkage rod 92 drives the top rod 93 to slide towards the fixed plug 82. The top rod 93 drives the fixed plug 82 to slide and insert into the fixed slot 81. The setting of the drive component 9 can drive the fixed plug 82 to insert into the fixed slot 81 when the insert 7 abuts against the bottom of the groove 6, thereby facilitating the drive of the fixed component 8.

[0037] Reference Figure 2 , Figure 3 and Figure 4A sliding block 10 is provided on the connecting pipe 51, and a driving component 9 is provided on the sliding block 10. The sliding block 10 slides towards or away from the fixed slot 81. The sliding of the sliding block 10 can drive the driving component 9 to slide away from the fixed slot 81, thereby allowing the fixed insert 82 to disengage from the fixed slot 81, facilitating the disassembly of the mesh part 52. A connecting flange 11 is provided at the connection point of both the temperature control pipe 4 and the connecting pipe 51. Bolts 12 and nuts 13 can be detachably installed on the connecting flange 11, which facilitates the disassembly and assembly of the temperature control pipe 4 and the connecting pipe 51. A sliding assembly 14 is slidably provided inside the connecting pipe 51. The sliding assembly 14 includes a sliding rod 141 and a sliding spring 142. The sliding rod 141 is fixed on the sliding block 10, and the end of the sliding rod 141 away from the sliding block 10 extends out of the connecting pipe 51. The sliding spring 142 is provided between the sliding block 10 and the connecting pipe 51. Between 1 and 2, the elastic force of the sliding spring 142 drives the sliding block 10 to slide towards the temperature control pipe 4. When the bolt 12 is installed on the connecting flange 11, the bolt 12 abuts against the sliding rod 141, driving the sliding rod 141 to slide away from the temperature control pipe 4. The setting of the sliding component 14 can drive the sliding block 10 to slide after the bolt 12 is installed, so that the sliding block 10 can drive the driving component 9 to be in a normal working state. At the same time, the sliding rod 141 can also abut against the bolt 12 due to the elastic force of the sliding spring 142, restricting the nut 13 from disengaging. Subsequently, by disassembling the bolt 12, the sliding block 10 can drive the driving component 9 to disengage from the working state. In this embodiment, since the connecting pipe 51 and the mesh part 52 are both columnar hollow structures, the top rod 93 in the driving component 9 in this embodiment is arc-shaped, and the sliding of the linkage rod 92 also slides along the arc direction. At the same time, the sliding block 10 as a whole is also arc-shaped.

[0038] Reference Figure 4 , Figure 5 and Figure 6 The mesh body 52 includes a lower mesh body 521 and a net body 522. The lower mesh body 521 and the net body 522 are horizontally divided by the mesh body 52. ​​Dividing the mesh body 52 into the net body 522 and the lower mesh body 521 facilitates cleaning of the inside of the mesh body 52 and reduces the probability of clogging. A sealing strip 15 is embedded at the connection between the lower mesh body 521 and the net body 522. The sealing strip 15 can improve the sealing performance when the net body 522 and the lower mesh body 521 are connected. A hook 16 is fixed on the net body 522. An insertion groove 17 and a snap-fit ​​groove 18 are opened on the lower mesh body 521. The hook 16 is inserted into the insertion groove 17 and snaps into the snap-fit ​​groove 18 by sliding, thereby realizing the installation and fixation between the net body 522 and the lower mesh body 521.

[0039] The implementation principle of this application embodiment is as follows: Select a suitable mesh part 52, insert the mesh part 522 onto the lower mesh part 521 through the hook 16 and slide and fix the mesh part 52, then install the mesh part 52 onto the connecting pipe 51, and at the same time connect and fix the temperature control pipe 4 to the connecting pipe 51, and connect both ends of the temperature control pipe 4 to the temperature control equipment, then connect multiple filter cylinders 1 end to end through the liquid inlet pipe 2 and the liquid outlet pipe 3, and connect the liquid inlet pipe 2 of the first filter cylinder 1 and the liquid outlet pipe 3 of the last filter cylinder 1 to the electroplating tank, thus completing the installation of the integrated electroplating tank liquid circulation and purification equipment on the electroplating tank.

[0040] 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.
