[0002] Electronic components are the basic units that make up an electronic circuit, such as resistors, capacitors, etc. During the production and processing of resistors, electroplating is usually required to provide a good soldering surface for the resistor and protect the resistor pins from corrosion. In order to ensure the electroplating quality of the resistor, a liquid circulation filtration device is often used to remove impurities in the electroplating solution and maintain the purity of the electroplating solution, thereby improving the uniformity, brightness, and adhesion of the electroplating layer.

[0003] After retrieval, the Chinese patent "Electroplating Liquid Circulation Device" with the authorization announcement number "CN220376813U" realizes the cleaning of the filter screen by the scraping strip through the threaded rod, the connecting plate, and the multi-stage telescopic rod, avoiding the blockage of the filter screen by impurities in the electroplating solution.

[0004] The impurities scraped by the above filter screen are not discharged from the box body, and the impurities in the box body will adhere to the filter screen again, thereby causing the blockage of the filter screen and affecting the filtration efficiency of the electroplating solution.

[0005] Therefore, a liquid circulation filtration device for the surface treatment of a mobile phone middle plate is proposed to solve the above problems. Content of the Utility Model

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] During specific implementation: As Figures 1-4 shown, a liquid circulation filtering device for the surface treatment of a mobile phone midplate includes: an electroplating frame 1, a filter box 2 is fixedly communicated with one side of the electroplating frame 1, a first liquid extraction pump 3 is fixedly communicated with one side of the filter box 2, a liquid storage tank 4 is fixedly communicated with the top of the first liquid extraction pump 3, a second liquid extraction pump 5 is fixedly communicated with the rear end of the liquid storage tank 4, and one end of the second liquid extraction pump 5 is fixedly communicated with the inner wall of the electroplating frame 1; a cleaning mechanism 6, the cleaning mechanism 6 is arranged inside the filter box 2; wherein, the cleaning mechanism 6 includes a filter frame 62 arranged inside the filter box 2, a cover plate 61 is clamped on the top of the filter box 2, four pull rods 63 are fixedly connected to the top of the filter frame 62, the four pull rods 63 are distributed in a rectangle, a scraping frame 65 is fixedly connected to the top of the filter frame 62, the outer surface of the scraping frame 65 contacts the inside of the filter box 2, four sealing soft pads 612 are fixedly connected to the inner wall of the cover plate 61, the surface of the pull rod 63 is slidably connected to the inside of the sealing soft pad 612, two support blocks 64 are fixedly connected to the inside of the filter box 2, and the upper end of the surface of the pull rod 63 is frustum-shaped.

[0025] After a batch of resistors are electroplated in the electroplating frame 1 and the electroplating solution in the electroplating frame 1 needs to be filtered, manually turn on the first liquid extraction pump 3. The first liquid extraction pump 3 extracts the electroplating solution in the electroplating frame 1, causing the electroplating solution to flow through the filter box 2. The filter frame 62 blocks the impurities in the electroplating solution. The filtered electroplating solution flows to the liquid storage tank 4 through the outlet end of the first liquid extraction pump 3, so that all the electroplating solution in the electroplating frame 1 flows to the liquid storage tank 4 after passing through the filter frame 62. After the filtration is completed, manually turn off the first liquid extraction pump 3 and turn on the second liquid extraction pump 5. The second liquid extraction pump 5 extracts the filtered electroplating solution in the liquid storage tank 4 and transports it into the electroplating frame 1. After the transportation is completed, manually turn off the second liquid extraction pump 5, so that the filtered electroplating solution in the electroplating frame 1 performs electroplating operations on the resistors, and the electroplating solution in the electroplating frame 1 is circulated and filtered for use.

[0026] As Figures 3-4 shown, a fixing frame 66 is slidably connected inside the cover plate 61. The surface of the fixing frame 66 is clamped inside the filter frame 62. One side of the fixing frame 66 is rotatably connected to a rotating rod 68. A limiting wheel 69 is fixedly connected to the surface of the rotating rod 68. The lower end of the surface of the limiting wheel 69 is clamped to the inner bottom wall of the cover plate 61. The overall shape of the limiting wheel 69 is oval.

[0027] When it is necessary to clean the filter frame 62 and the inside of the filter box 2, at this time, all the electroplating solution in the electroplating frame 1 is transported to the liquid storage tank 4. Because the first liquid extraction pump 3 stops operating, and there is a check valve in the first liquid extraction pump 3, which is a known prior art, so it will not be elaborated here. The electroplating solution in the liquid storage tank 4 will not flow back into the filter box 2. At this time, rotate the rotating rod 68. The rotation of the rotating rod 68 drives the limiting wheel 69 to rotate, so that the lower end of the surface of the limiting wheel 69 moves away from the inner bottom wall of the cover plate 61. Pull the rotating rod 68. The movement of the rotating rod 68 drives the fixing frame 66 to move and squeeze the elastic piece 67 and move away from the inside of the filter box 2. Pull the cover plate 61 so that the cover plate 61 moves away from the inside of the filter box 2. At this time, pull the pull rod 63. The upward movement of the pull rod 63 drives the filter frame 62 and the scraping frame 65 to move upward. The scraping frame 65 in the upward movement scrapes the inner wall of the filter box 2, so that the scraped impurities are pushed away from the inside of the filter box 2. The filter frame 62 moves away from the inside of the filter box 2, and the filter frame 62 can be cleaned, ensuring the cleanliness of the filter frame 62 and the inside of the filter box 2.

[0028] As Figure 4 shown, two elastic pieces 67 are fixedly connected to one side of the fixing frame 66. The other ends of the elastic pieces 67 are fixedly connected to the inner wall of the cover plate 61. A long rod 610 is slidably connected to the inner wall of the rotating rod 68. The surface of the long rod 610 is clamped inside the cover plate 61. The lower end of the surface of the rotating rod 68 is fixedly connected to an elastic rope 611. The bottom end of the elastic rope 611 is fixedly connected to one side of the filter box 2.

[0029] After the filter frame 62 is cleaned, place the filter frame 62 in the filter box 2 so that the bottom of the filter frame 62 abuts against the top of the support block 64. Since the upper end of the surface of the pull rod 63 is frustum-shaped, the cover plate 61 can be quickly inserted onto the pull rod 63 and clamped on the top of the filter box 2. The lower end of the surface of the cover plate 61 closely adheres to the inside of the filter box 2. The elastic force of the elastic piece 67 pushes the fixed frame 66 to move and be clamped inside the filter box 2. Rotate the rotating rod 68. The rotation of the rotating rod 68 drives the limiting wheel 69 to rotate, so that the lower end of the surface of the limiting wheel 69 is clamped on the inner bottom wall of the cover plate 61. Insert the long rod 610 into the rotating rod 68 and push it to be clamped inside the cover plate 61, so that the cover plate 61 is stably installed on the filter box 2.

[0030] When the present utility model is in use, all the electroplating solution in the electroplating frame 1 is transported into the liquid storage tank 4. Since the first liquid extraction pump 3 stops operating, and there is a check valve in the first liquid extraction pump 3, which is a well-known prior art, so it will not be described here. Thus, the electroplating solution in the liquid storage tank 4 will not flow back into the filter box 2. At this time, rotate the rotating rod 68. The rotation of the rotating rod 68 drives the limiting wheel 69 to rotate, so that the lower end of the surface of the limiting wheel 69 moves away from the inner bottom wall of the cover plate 61. Pull the rotating rod 68. The movement of the rotating rod 68 drives the fixed frame 66 to move and squeeze the elastic piece 67 and move away from inside the filter box 2. Pull the cover plate 61 so that the cover plate 61 moves away from inside the filter box 2. At this time, pull the pull rod 63. The upward movement of the pull rod 63 drives the filter frame 62 and the scraping frame 65 to move upward. The scraping frame 65 during the upward movement scrapes the inner wall of the filter box 2, so that the scraped impurities are pushed away from inside the filter box 2. The filter frame 62 moves away from inside the filter box 2, and thus the filter frame 62 can be cleaned, ensuring the cleanliness inside the filter frame 62 and the filter box 2.

[0031] It should be noted that in the above description, the first liquid extraction pump 3, the second liquid extraction pump 5, the sealing soft pad 612, the elastic piece 67, the scraping frame 65, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the first liquid extraction pump 3 and the second liquid extraction pump 5 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be described here.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
