Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a dry membrane residue filter basket. Background Technology

[0002] Dry film residue is generated during circuit board processing, primarily used in pattern plating and etching processes. The dry film's main function is to protect the copper layers that don't need to be etched away, ensuring that only predetermined areas of copper are removed to form the desired circuit pattern. After etching, the dry film is removed from the circuit board using a specialized cleaning agent. The removed dry film residue is then filtered through a filter basket to prevent interference with the reuse of the cleaning agent. Currently used filter baskets have filter holes and a filter screen at the bottom. During filtration, the dry film residue accumulates in localized areas. To avoid affecting subsequent filtration, operators often need to scrape or remove it. Because the amount of dry film residue collected is unpredictable, frequent monitoring by operators is necessary. Utility Model Content

[0003] This utility model provides a dry membrane residue filter basket to overcome the shortcomings of the prior art, improve the treatment effect of dry membrane residue, and avoid the accumulation of dry membrane residue from affecting the filtration and impurity removal of the cleaning agent, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A dry membrane residue filter basket includes a filter cover with a rectangular internal structure. Multiple perforations are located at the bottom of the filter cover. A rectangular frame is positioned inside the filter cover, and a filter membrane is placed within the rectangular frame. The rectangular frame is angled within the filter cover. The angled rectangular frame and filter membrane facilitate the filtration of cleaning agents and, during filtration, allow the dry membrane residue to accumulate at a designated location, thus preventing it from obstructing the passage of cleaning agents. The angled filter membrane also improves the throughput of the cleaning agents. Triangular shells are fixed to both sides of the filter cover, and connecting holes are provided on both sides. The shells are positioned at the connecting holes, with the rectangular frame angled downwards at one end of the connecting hole. The shells and connecting holes facilitate the removal of the filtered dry membrane residue. A scraper is provided on the filter cover for easy removal of dry membrane residue from the upper side of the filter membrane by the operator.

[0006] Furthermore, to prevent the cleaning agent from leaking out and making it inconvenient to collect, a rubber block is provided inside the outer end of the shell, and an end cap is provided at the outer end of the rubber block.

[0007] Furthermore, in order to fix the end cap and ensure its sealing effect, a convex plate is provided on the upper side of the housing. A hinge shaft is provided at the upper end of the convex plate, and a rotating arm is rotatably provided on the hinge shaft. An end plate is installed on the outer end of the rotating arm by screws. An inner top screw is connected to the end plate by threads. A rotating head is provided on the outer end of the inner top screw, and an inner top cap is provided on the inner end of the inner top screw. The inner end of the inner top cap acts on the end cap.

[0008] Furthermore, to ensure a secure seal, an insert rod is provided on the end cap, which passes through the inner top cap.

[0009] Furthermore, in order to facilitate the discharge of cleaning agent from inside the housing, multiple drainage holes are provided on one side of the housing, and the drainage holes are located on the downward-facing side of the housing.

[0010] Furthermore, the upper end of the filter cover is formed with a ring plate, a baffle plate is installed on the ring plate, and a feed frame is connected to the baffle plate. The baffle plate and the feed frame can prevent the cleaning agent from splashing out.

[0011] Furthermore, to facilitate the scraping of dry film residue, a pair of transverse holes are provided on the shielding plate. Multiple connecting rods are inserted through the transverse holes. The upper end of the connecting rod is connected to a movable plate by a thread, and the lower end of the connecting rod is connected to a movable arm by a thread. The lower end of the movable arm is located on the scraper plate.

[0012] Furthermore, a concave handle is provided on the moving plate to facilitate the scraping operation.

[0013] The advantages of the above technical solution are:

[0014] This invention facilitates the scraping and removal of dry membrane residue on the filter membrane, and reduces the impact of dry membrane residue on the filtration of cleaning agents. Attached Figure Description

[0020] Figure 5 A three-dimensional structure of one embodiment is shown. Figure 3 . Detailed Implementation

[0021] like Figures 1-5 As shown, a dry membrane residue filter basket includes a filter cover 1, the internal space of which is a cuboid structure, and the bottom of the filter cover 1 has multiple holes 13.

[0022] The filter cover 1 has a rectangular frame 2 inside, and a filter membrane 20 is installed inside the rectangular frame 2. The rectangular frame 2 is installed at an angle inside the filter cover 1.

[0023] A triangular housing 11 is fixed to both sides of the filter cover 1. Multiple leakage holes are provided on one side of the housing 11, and connecting holes 12 are provided on both sides of the filter cover 1. The housing 11 is positioned at the connecting holes 12, and the rectangular frame 2 is inclined downwards at one end of the connecting hole 12. A rubber block is provided inside the outer end of the housing 11, and an end cap 35 is provided at the outer end of the rubber block. A protruding plate 3 is provided on the upper side of the housing 11, and a hinge shaft is provided at the upper end of the protruding plate 3. A rotating arm 30 is rotatably mounted on the hinge shaft. An end plate 31 is installed on the outer end of the rotating arm 30 by screws. An inner top screw 32 is threaded onto the end plate 31. A rotating head 33 is provided at the outer end of the inner top screw 32, and an inner top cap 34 is provided at the inner end of the inner top screw 32. The inner end of the inner top cap 34 acts on the end cap 35. Furthermore, an insertion rod is provided on the end cap 35, and the insertion rod passes through the inner top cap 34.

[0024] The filter cover 1 is equipped with a scraper 53. The upper end of the filter cover 1 is formed with a ring plate 10. A baffle plate 4 is installed on the ring plate 10. The baffle plate 4 is made of transparent material. A feed frame 42 is connected to the baffle plate 4. A pair of transverse holes 40 are opened on the baffle plate 4. Multiple connecting rods 5 pass through the transverse holes 40. The upper end of the connecting rod 5 is connected to a moving plate 50 by a thread. The moving plate 50 is equipped with a concave handle 51. The lower end of the connecting rod 5 is connected to a moving arm 52 by a thread. The lower end of the moving arm 52 is located on the scraper 53.

[0025] In this embodiment, the filter cover 1 is placed at the outlet of the cleaning agent, and the outlet of the cleaning agent is located directly above the feed frame 42. The feed frame 42 is located at the upper end of the filter membrane 20. When the cleaning agent is discharged through the outlet, it will flow downward from the upper end of the filter membrane 20 to impact the dry membrane residue to the lower end of the filter membrane 20. Some of the cleaning agent will flow downward directly through the filter membrane 20 and then be collected for reuse.

[0026] During the filtration process, the operator moves the scraper 53 as needed. In the process of scraping off the dry film residue, the scraper 53 is generally moved left and right to remove the residue, so as to prevent the dry film residue from accumulating too much in one of the housings 11 and affecting the discharge of the dry film residue. When the dry film residue accumulates too much, the inner top screw 32 is loosened first, and then the end cap 35 is removed from the housing 11. The filtered dry film residue is then discharged, and the housing 11 is sealed again through the end cap 35 after discharge.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
