[0001] The present invention relates to the technical field of cleaning equipment for computer aluminum cases, and particularly to a cleaning device and method for processing computer aluminum cases. Background Art

[0002] In the production process of computer aluminum cases, the aluminum alloy raw materials are first precisely processed by a CNC machine tool, and are processed by processes such as cutting, milling, and drilling to form the precise shape and specifications required for the computer aluminum cases. However, during the CNC machining process, cutting fluid is used to cool the cutting tool and the workpiece, while reducing friction and wear. This results in the surface of the machined aluminum case being left with cutting fluid, dust, metal powder, and other stains, which has an adverse effect on subsequent processing.

[0003] Therefore, the machined computer aluminum cases need to be cleaned by a dedicated cleaning device to remove the stains on the surface and ensure the cleanliness and appearance quality of the computer aluminum cases. Traditional cleaning methods for computer aluminum cases mostly use manual operation, which is not only inefficient, but also difficult to guarantee the cleaning quality, and there are certain safety hazards. Moreover, there are a series of problems with the computer aluminum case cleaning equipment in the prior art.

[0004] Especially during the cleaning process, the cleaning steps of the computer aluminum case are cumbersome, which not only increases the operation difficulty, but also prolongs the cleaning cycle. The cleaning effect is not ideal, and the stains and tiny burrs on the surface of the aluminum case cannot be completely removed.

[0005] Therefore, there is an urgent need for a cleaning device for computer aluminum case production that is simple in structure, convenient to operate, and has a good cleaning effect to solve the problems existing in the prior art. The present invention aims to provide a cleaning device for computer aluminum cases that can adopt a variety of cleaning technologies to achieve efficient and precise cleaning of aluminum cases while avoiding damage to the aluminum cases.

[0015] The beneficial effects of the present invention are as follows: 1. By integrating two technologies of dry ice cleaning and steam cleaning, the present invention can efficiently remove stains, grease, and micro burrs on the surface of the computer aluminum shell. Dry ice cleaning utilizes the high-speed impact and low-temperature freezing characteristics of dry ice particles to achieve precise cleaning and deburring. Steam cleaning uses high-pressure and high-temperature steam to deeply clean the aluminum shell to ensure the cleaning effect. The present invention uses part of the steam generated by the steam generator to drive the steam turbine, and then drives the drying fan mechanism to work, realizing the recycling of energy and saving energy costs; In addition, the gas generated during the dry ice cleaning process is recovered and processed through the gas recovery component. After purification by the filter screen and the activated carbon adsorption layer, it is finally discharged into the carbon dioxide gas collection tank, reducing the emission of harmful gases and meeting the environmental protection requirements. At the same time, neither dry ice cleaning nor steam cleaning requires the use of chemical cleaning agents, reducing environmental pollution. 2.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 In this embodiment, preferably, the placement basket component 3 includes a placement frame 31, a plurality of limit blocks 32, and two handles 33. A cavity is provided in the placement frame 31. The plurality of limit blocks 32 are evenly divided into two groups.

The two handles 33 are symmetrically arranged at the top ends of the two side walls of the placement frame 31 respectively; the handles 33 are used to facilitate the handling of the placement basket component 3. In this embodiment, the surface of the placement frame 31 is coated with PA gray glue to prevent the computer aluminum shell from being scratched and water marks from being generated by collisions. The insertion type placement facilitates quick taking, and at the same time is conducive to batch processing of the computer aluminum shell to improve efficiency.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7, preferably in this embodiment, the limiting member includes limiting plates 71 symmetrically arranged on both sides inside the first frame 41 and the second frame 61. A number of groups of auxiliary wheel mechanisms 72 are arranged on the limiting plates 71. The auxiliary wheel mechanisms 72 are used to limit the movement range of the placement basket member 3 and ensure the angle stability of the computer aluminum shell during the cleaning process. The auxiliary wheel mechanism 72 includes a sliding rod 721, a connecting rod 722, a pulley 723 and a spring 724; the sliding rods 721 are symmetrically and slidably arranged at the upper and lower ends of the limiting plate 71 respectively. One end of the sliding rod 721 penetrates the limiting plate 71, and the other end of the sliding rod 721 is connected with a connecting rod 722. A spring 724 is arranged in the middle of the limiting plate 71 and the sliding rod 721 near one end of the connecting rod 722.

Dry ice cleaning stage: When the placement basket member 3 enters the first cleaning chamber of the dry ice cleaning member 4 through the curtain door 42, the liquid carbon dioxide in the liquid carbon dioxide storage tank 43 is transported to the dry ice nozzle 44 through a pipeline, and the dry ice nozzle 45 releases dry ice particles to clean the computer aluminum shell; at the same time, the gas recovery component 5 is started, and the gas generated during the cleaning process is inhaled through the suction port of the recovery smoke pipe 51. After the gas is processed by the filter screen 52 and the activated carbon adsorption layer, it is finally discharged into the carbon dioxide gas collection tank 54; S3. Steam cleaning and drying stage: After the cleaning is completed, the placement basket component 3 continues to move forward and enters the second cleaning chamber of the cleaning and drying component 6. The steam cleaning mechanism is activated. The steam generator 62 pumps water from the water tank 63 through a pump, generates steam, and evenly sprays the steam on the computer aluminum shell through the steam nozzle 64 for in-depth cleaning; After the cleaning is completed, the drying fan mechanism is activated. At this time, the steam generated by the steam generator 62 drives the steam turbine 65 to rotate. The driving gear 664 connected to the rotating shaft end of the steam turbine 65 rotates accordingly. Through the transmission of the belt 666, the driven gear 665 is driven to rotate, and then the rotating shaft 663 and the rotating blades 662 are driven to rotate to generate hot air to dry the computer aluminum shell.

[0027] In summary, by integrating two technologies of dry ice cleaning and steam cleaning, the present invention can efficiently remove stains, grease, and micro burrs on the surface of the computer aluminum shell. Dry ice cleaning utilizes the high-speed impact and low-temperature freezing characteristics of dry ice particles to achieve precise cleaning and deburring. Steam cleaning uses high-pressure and high-temperature steam to deeply clean the aluminum shell to ensure the cleaning effect. The present invention uses part of the steam generated by the steam generator 62 to drive the steam turbine 65, and then drives the drying fan mechanism to work, realizing the recycling of energy and saving energy costs; In addition, the gas generated during the dry ice cleaning process is recovered and treated through the gas recovery component 5. After being purified by the filter screen 52 and the activated carbon adsorption layer, it is finally discharged into the carbon dioxide gas collection tank 54, reducing the emission of harmful gases and meeting the environmental protection requirements. At the same time, neither dry ice cleaning nor steam cleaning requires the use of chemical cleaning agents, reducing environmental pollution. The present invention can simultaneously process multiple computer aluminum shells through the plug-in placement design of the placement basket component 3, avoiding the collision of computer aluminum shells, and using the gaps between computer aluminum shells for efficient cleaning. The design of the limiting component and the auxiliary wheel mechanism 72 ensures the stability and angle stability of the computer aluminum shell during the cleaning process, further improving the cleaning quality.
