[0002] Electroplating solutions are liquids that can expand the range of cathode current densities for metals, improve the appearance of the plating layer, and increase the stability of the solution against oxidation. They are widely used in the production of electronic components such as semiconductor chips.
[0003] After a period of use, electroplating solutions will become contaminated with harmful substances such as mud, sediment, and metal ions. In order to ensure the purity and stability of the electroplating solution and improve the quality and surface smoothness of electroplated products, the electroplating solution needs to be filtered frequently. The existing filtration machine has a complicated filtration process and is prone to failure during use, which affects the electroplating process. Utility Model Content
[0004] To solve the above-mentioned technical problems, this application provides an electroplating liquid filter, which is achieved through the following technical solution:
[0005] An electroplating liquid filter includes a tank and a base. The tank is mounted on the base, and a water pump is installed inside the base. The tank includes a top cover and a filtering device. The filtering device includes a distributor and a chassis. A plurality of filter elements are disposed between the distributor and the chassis. The distributor is disc-shaped and has a plurality of distribution holes on its surface. Each distribution hole is fitted onto the top of a filter element. The bottom of the filter element is sealed and fixedly connected to the chassis. The filter element includes a support tube with a plurality of filter holes on its wall and filter media on its outer wall.
[0006] The top cover and the distributor are sealed together, forming an inlet chamber. The inlet end of the water pump is connected to the electroplating solution tank through a pipe, and the outlet end is connected to the top cover through a pipe. A pressure pump is also connected to the top cover.
[0007] The chassis is sealed to the inner wall of the tank, and a liquid collection chamber is formed between the chassis and the distributor. A liquid outlet valve is connected to the outer wall of the tank corresponding to the liquid collection chamber.
[0008] As a preferred embodiment, the filter material is textile fiber precisely wound on the outer wall of the support tube.
[0009] As a preferred embodiment, a pressure gauge and a pressure relief valve are connected to the portion of the tank corresponding to the outer wall of the liquid collection chamber.

The filtration process is simple, which can effectively improve the filtration rate. The filtered electroplating liquid does not enter the bottom of the tank, avoiding the deposition of electroplating liquid at the bottom of the tank and causing corrosion, thus effectively improving the service life of the tank.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0020] An electroplating liquid filter includes a tank 1 and a base 2. The tank 1 is mounted on the base 2. A water pump 3 is installed inside the base 2. The tank 1 includes a top cover 4 and a filter device 5. The filter device 5 includes a distributor 51 and a base 52. A plurality of filter elements 6 are disposed between the distributor 51 and the base 52. The distributor 51 is disc-shaped and has a plurality of distribution holes 53 on its surface. Each distribution hole 53 is correspondingly clamped to the top of a filter element 6. The bottom of the filter element 6 is sealed and fixedly connected to the base 52. The filter element 6 includes a support tube 61. A plurality of filter holes 62 are opened on the wall of the support tube 61. Filter material 63 is provided on the outer wall of the support tube 62.
[0021] The top cover 4 and the distributor 51 are sealed together, and the top cover 4 and the distributor 51 form a liquid inlet chamber 7. The feed end of the water pump 3 is connected to the electroplating solution tank 9 through a pipe 8, and the discharge end is connected to the top cover 4 through a pipe 91. A pressure pump 10 is also connected to the top cover 4.
[0022] The chassis 52 is sealed to the inner wall of the tank 1, and a liquid collection chamber 11 is formed between the chassis 52 and the distributor 51. A liquid outlet valve 12 is connected to the outer wall of the tank 1 corresponding to the liquid collection chamber 11.
[0023] Furthermore, the filter material 63 is textile fiber precisely wound on the outer wall of the support tube.
[0024] Furthermore, a pressure gauge 13 and a pressure relief valve 14 are connected to the portion of the outer wall of the tank body 1 corresponding to the liquid collection chamber 11.
[0025] Furthermore, the material of the tank body 1 is polypropylene or acrylic.
[0026] When the electroplating liquid filter is in use, the water pump 3 pumps the liquid to be filtered from the electroplating liquid tank 9 into the inlet chamber 7. Due to the setting of the distributor 51, the electroplating liquid in the inlet chamber 7 enters the support tube 61 through the distribution holes 53 on the distributor 51. Several filter holes 62 are opened on the wall of the support tube 61. The electroplating liquid in the support tube 61 seeps into the filter material 63 through the filter holes 62 and is filtered by the filter material 63. The filter material 63 is a textile fiber that is precisely wound on the outer wall of the support tube. That is, the textile fiber is cross-woven on the outer wall of the support tube 61. The filter holes formed in this way are large on the outside and small on the inside, which has an excellent deep filtration effect and can effectively remove suspended solids, particles and other impurities in the electroplating liquid.
[0027] A pressure pump 10 is also connected to the top cover 4. The pressure pump pressurizes the liquid inlet chamber 7, which can improve the filtration rate. The filtered electroplating solution flows into the bottom of the liquid collection chamber 11 and is discharged through the liquid outlet valve 12 as needed.
[0028] The specific implementation of this utility model has been described in detail above, but it is only an example. This utility model is not limited to the specific implementation cases described above, and equivalent modifications to this utility model are also within the protection scope of this utility model.
