[0003] After processing, the filter needs to be cleaned to remove processing residues such as polishing powder, so as to ensure the surface of the filter is clean and avoid performance defects during subsequent coating or use.

[0004] Ultrasonic cleaning can remove residues from optical filters, but the polishing powder and other impurities removed during cleaning will float on the liquid surface, causing them to re-adhere when the optical filter is removed. Therefore, this invention proposes an optical filter cleaning device that can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filter cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filter cleaning device, comprising a cleaning tank and a support frame, wherein the cleaning tank has an ultrasonic generating module and is filled with cleaning solvent, and two sets of moving rods are slidably fitted on the upper end of the cleaning tank, each set of moving rods being connected to a scraper extending into the cleaning tank, and the two sets of scrapers being able to abut against each other to form a seal;

[0007] The support frame has a mesh frame plate, and multiple sets of perforated plates are provided on the inner side of the mesh frame plate. Each set of perforated plates has a cavity for placing multiple filters.

[0008] The cleaning tank is connected to a bracket via a lifting assembly. The bracket supports the carrier frame and can move vertically to submerge the carrier frame in the cleaning solvent or expose it to the cleaning solvent.

[0009] As a preferred technical solution, the upper end of the support frame has a lifting handle.

[0010] As a preferred technical solution, the lifting assembly includes multiple sets of guide rods disposed on the bracket, the multiple sets of guide rods passing downward through the cleaning tank and connected to a liner.

[0011] As a preferred technical solution, a support frame is provided at the bottom of the cleaning tank, an electric cylinder is installed on the support frame, and a push block is connected to the movable rod of the electric cylinder, which can push the liner plate to move upward.

[0015] As a preferred technical solution, a pressure strip is placed on the movable mesh plate, and the pressure strip is used to press the filter layer.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] After cleaning, move the two sets of moving rods to move the two sets of scrapers away from each other, scraping away the polishing powder and other impurities floating on the surface of the cleaning solvent, thus forming a clean area above the support frame. The lifting component moves the bracket upward, causing the support frame to be exposed above the cleaning solvent in the clean area. At this time, the staff removes the support frame from the cleaning box to complete the cleaning of the filter. This can effectively prevent the polishing powder and other impurities removed during cleaning from re-adhering to the filter, thus improving the cleaning effect.

[0018] After the two sets of scrapers are moved away from each other and scrape away the polishing powder on the surface of the clean liquid, the levers are pulled up to move the movable screen upwards. The polishing powder is then filtered out of the liquid surface through the filter layer, thereby effectively reducing the polishing powder content in the cleaning solvent, reducing the frequency of cleaning solvent replacement, and saving cleaning costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4

[0026] Example 1

[0027] Provide a filter cleaning device:

[0028] The cleaning tank 10 has an ultrasonic generator module and is filled with cleaning solvent. The ultrasonic generator module generates a high-frequency oscillating electrical signal and converts it into a high-frequency vibration that is transmitted into the cleaning solvent to clean the filter. The cleaning tank 10 also has a pipe with a control valve installed on it.

[0029] Two sets of moving rods 11 are slidably fitted into the upper end of the cleaning tank 10. Each set of moving rods 11 is connected to a scraper 12 extending into the cleaning tank 10. The two sets of scrapers 12 can abut against each other to form a seal. The two sets of moving rods 11 can drive the scrapers 12 away from each other to scrape away the polishing powder floating on the surface of the cleaning solvent, thereby forming a clean area.

[0030] The support frame 20 has a mesh frame plate 21, and multiple sets of perforated plates 22 are provided on the inner side of the mesh frame plate 21. Each set of perforated plates 22 has multiple cavities for placing filters, and the inner wall of the cavity has a rubber layer. Each cavity holds one filter. The upper end of the support frame 20 has a lifting handle 23, which makes it easy for staff to pick up and put down the support frame 20 through the lifting handle 23. Staff need to wear gloves when picking up and putting down the filter.

[0031] The cleaning tank 10 is connected to the bracket 40 via the lifting assembly 30. The bracket 40 is located inside the cleaning tank 10. Each set of guide rods 31 is provided with a rubber water-proof ring to seal and prevent the cleaning solvent inside the cleaning tank 10 from leaking out.

[0032] The bracket 40 is used to support the carrier 20. After the filter to be cleaned is placed in the multiple cavities, the carrier 20 is placed in the cleaning tank 10 and supported by the bracket 40. The bracket 40 can move vertically to submerge the carrier 20 downwards into the cleaning solvent or expose it upwards in the cleaning solvent. During cleaning, the carrier 20 is submerged in the cleaning solvent and will not come into contact with polishing powder or other impurities on the surface of the cleaning solvent.

[0033] The lifting assembly 30 includes multiple sets of guide rods 31 mounted on the bracket 40. The guide rods 31 pass downward through the cleaning tank 10 and are connected to a liner 32. A support frame 33 is provided at the bottom of the cleaning tank 10. An electric cylinder body 34 is mounted on the support frame 33. A push block 35 is connected to the movable rod of the electric cylinder body 34. The push block 35 can push the liner 32 upward.

[0034] Specifically, the filters to be cleaned are first placed in the multiple cavities on the support frame 20. Then, the support frame 20 is placed in the cleaning tank 10, supported by the bracket 40 and submerged in the cleaning solvent. Next, the two sets of moving rods 11 are moved so that the two sets of scrapers 12 move closer to each other and move to the center above the support frame 20 to form a seal. Then, the ultrasonic generator module is controlled to work at regular intervals to clean the filters. After cleaning, the two sets of moving rods 11 are moved again so that the two sets of scrapers 12 move further apart, scraping away the polishing powder and other impurities floating on the surface of the cleaning solvent, thus forming a clean area above the support frame 20. The lifting component 30 moves the bracket 40 upward, causing the support frame 20 to be exposed above the cleaning solvent in the clean area. At this time, the staff removes the support frame 20 from the cleaning tank 10 to complete the cleaning of the filters. This effectively prevents the polishing powder and other impurities removed during cleaning from re-adhering to the filters, improving the cleaning effect.

[0035] Example 2

[0036] Provide a filter cleaning device:

[0037] The lower end of the frame plate 21 is provided with multiple sets of positioning blocks 24, and the bracket 40 has more than one set of through slots 41. The multiple sets of positioning blocks 24 can be inserted into the multiple sets of through slots 41 one by one to achieve positioning.

[0038] A power motor 36 is installed on the support frame 33. The output end of the power motor 36 is connected to a cam 37. The cam 37 can abut against the liner 32. During the cleaning process, the power motor 36 drives the cam 37 to rotate. The liner 32 drives the bracket 40 to move vertically and reciprocally through multiple sets of columns, thereby causing the support frame 20 to move up and down in the cleaning solvent, improving the scouring effect of the cleaning solvent on the filter and effectively removing the residue on the filter.

[0039] Rubber strips are provided on both sides of the scraper 12 to abut against the inner wall of the cleaning tank 10, so that polishing powder will not leak out from both sides when the scraper 12 moves.

[0040] Pull rods 13 are respectively installed on both sides of the inside of the cleaning tank 10. The pull rods 13 extend into the cleaning tank 10 and are connected to a movable screen plate 14. A filter layer 15 is laid on the movable screen plate 14. The filter layer 15 is preferably made of filter cotton or other materials. A pressure strip 16 is placed on the movable screen plate 14 to press the filter layer 15. After the two sets of scrapers 12 are moved away from each other and scrape away the polishing powder on the surface of the clean liquid, the pull rods 13 are pulled to make the movable screen plate 14 move upward. The polishing powder is filtered out from the liquid surface through the filter layer 15, thereby effectively reducing the polishing powder content in the cleaning solvent, reducing the frequency of changing the cleaning solvent, and saving cleaning costs.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
