Description

Technical Field

[0001] This invention relates to the field of cleaning equipment for computer aluminum casings, and more particularly to a cleaning apparatus and method for processing computer aluminum casings. Background Technology

[0002] In the production process of computer aluminum casings, the aluminum alloy raw material is first precision-machined using CNC machine tools, undergoing processes such as cutting, milling, and drilling to form the precise shape and specifications required for the computer aluminum casing. However, cutting fluid is used during CNC machining to cool the tools and workpiece, while also reducing friction and wear. This results in cutting fluid, dust, metal powder, and other stains remaining on the surface of the machined aluminum casing, adversely affecting subsequent processing.

[0003] Therefore, the processed aluminum computer casings need to be cleaned using specialized cleaning equipment to remove surface stains and ensure cleanliness and aesthetic quality. Traditional cleaning methods for aluminum computer casings mostly rely on manual operation, which is not only inefficient and difficult to guarantee in terms of cleaning quality, but also poses certain safety hazards. Furthermore, existing aluminum computer casing cleaning equipment suffers from a series of problems.

[0004] Especially during the cleaning process, the cleaning steps for the aluminum casing of the computer are cumbersome, which not only increases the difficulty of operation but also prolongs the cleaning cycle. The cleaning effect is not ideal, and it is impossible to completely remove stains and tiny burrs from the surface of the aluminum casing.

[0005] Therefore, there is an urgent need for a cleaning device for computer aluminum casing production that is simple in structure, easy to operate, and provides good cleaning results, in order to solve the problems existing in the prior art. This invention aims to provide a cleaning device for computer aluminum casings that can employ multiple cleaning technologies to achieve efficient and precise cleaning of the aluminum casings while avoiding damage. Summary of the Invention

[0006] To achieve the above-mentioned objectives of this invention, the invention is implemented through the following technical solution: a cleaning device for processing computer aluminum shells, comprising a conveying component and an electrical control box. The conveying component consists of several conveying rollers. A basket component is disposed above the conveying component to support the computer aluminum shell to be cleaned. A dry ice cleaning component is also disposed above the conveying component to perform dry ice cleaning and deburring on the computer aluminum shell. The dry ice cleaning component has a first cleaning chamber, and a gas recovery component is disposed within the first cleaning chamber to recover the gas generated during the cleaning process. A cleaning and drying component is disposed behind the dry ice cleaning component to clean and dry the computer aluminum shell. A second cleaning chamber is disposed within the cleaning and drying component. Limiting components are disposed in both the first and second cleaning chambers to assist in limiting the placement basket component, ensuring the stability of the computer aluminum shell during the cleaning process.

[0007] A further improvement is that the placement basket component includes a placement frame, multiple limiting blocks, and two handles. The placement frame has a cavity, and the multiple limiting blocks are divided into two groups. The two groups of limiting blocks are symmetrically arranged on the top and bottom sides of the inner wall of the placement frame to divide the cavity into multiple parts for placing multiple computer aluminum shells. The two handles are symmetrically arranged on the top of the two side walls of the placement frame for convenient handling of the placement basket component.

[0008] A further improvement is made in that: the dry ice cleaning component includes a first frame with openings at both ends and a curtain door on each opening to increase the sealing of the cleaning chamber; a liquid carbon dioxide storage tank is provided on one side of the first frame; and several sets of dry ice nozzles are provided at the top of the first frame, each nozzle having several dry ice spray nozzles. The liquid carbon dioxide storage tank is connected to the dry ice nozzles via a pipe, and dry ice particles are released through the dry ice nozzles. Utilizing their high-speed impact and low-temperature freezing properties, the particles collide with the gap between the computer's aluminum casing, effectively removing not only stains and grease from the surface of the aluminum casing but also removing tiny burrs.

[0009] A further improvement is made in that: the gas recovery component includes a recovery flue pipe disposed on one side of the first frame, one end of the recovery flue pipe is provided with an air intake, the air intake is provided with a filter screen, and a negative pressure air mechanism is provided inside the filter screen. The negative pressure air mechanism is used to generate negative pressure to draw in gas. The negative pressure air mechanism includes a first motor, a fixing frame and a fan. The first motor is fixedly connected to the middle of the fixing frame, and the output end of the first motor is connected to the fan to drive the fan to rotate to generate negative pressure. The other end of the recovery flue pipe is connected to a carbon dioxide gas collection tank, which is used to collect the treated gas. An activated carbon adsorption layer is provided in the middle of the recovery flue pipe, which is used to further purify the inhaled gas.

[0010] A further improvement is made in that: the cleaning and drying component includes a second frame disposed above the conveying component, and a steam cleaning mechanism is disposed within the second frame. The steam cleaning mechanism is used to perform steam cleaning on the aluminum casing of the computer. A drying fan mechanism is also disposed behind the steam cleaning mechanism. The drying fan mechanism is used to dry the cleaned aluminum casing of the computer. The steam cleaning mechanism includes a steam generator, a water tank, a pump, steam nozzles, and a steam turbine. The steam generator is disposed on one side of the second frame and is used to generate high-pressure, high-temperature steam. One end of the steam generator is connected to the water tank through the pump, and the other end of the steam generator is connected to several steam nozzles through a hose. Several sets of steam nozzles are evenly disposed between the conveying rollers. One end of the steam generator is connected to the steam turbine, and a drive gear is disposed at the rotating shaft end of the steam turbine.

[0011] A further improvement is that the drying fan mechanism includes a fan housing, rotating blades, a rotating shaft, a driven gear, and a belt. Several sets of fan housings are arranged above the second frame. The rotating shaft passes through and is rotatably arranged inside several sets of fan housings. The rotating blades are arranged outside the rotating shaft. A driven gear is arranged at one end of the rotating shaft. The driving gear and the driven gear are connected by a belt.

[0012] A further improvement is made in that: the limiting component includes limiting plates symmetrically arranged on both sides inside the first frame and the second frame. The limiting plates are provided with several sets of auxiliary wheel mechanisms. The auxiliary wheel mechanisms are used to limit the movement range of the basket component and to ensure the angular stability of the computer aluminum shell during the cleaning process. The auxiliary wheel mechanism includes two sliding rods, one connecting rod, two pulleys and two springs. The two sliding rods are symmetrically slidably arranged at the upper and lower ends of the limiting plate. One end of the two sliding rods passes through the limiting plate, and the other end of the two sliding rods is connected to both ends of the connecting rod. The two springs are respectively sleeved on the outer periphery of the section of the two sliding rods near the connecting rod and the limiting plate. The two pulleys are rotatably arranged on the outside of the connecting rod.

[0013] A further improvement is that two sets of limiting rods are provided on each side of the placement frame. The limiting rods are provided with grooves that are adapted to the pulleys to ensure the stability of the computer aluminum casing during the cleaning process.

[0014] The above-mentioned cleaning device for computer aluminum casing processing is used in the following steps:

[0015] S1. Preparation stage: Insert the aluminum computer case to be cleaned into the placement frame of the placement basket component, use the limit block to ensure the aluminum case is stable, start the conveying component through the electrical control box, so that the placement basket component and the aluminum computer case inside it move forward along the conveying rollers.

[0016] S2, Dry Ice Cleaning Stage: When the basket component enters the first cleaning chamber of the dry ice cleaning component through the curtain door, liquid carbon dioxide in the liquid carbon dioxide storage tank is transported to the dry ice nozzle through the pipeline. The dry ice nozzle releases dry ice particles to clean the computer aluminum casing. At the same time, the gas recovery component is activated, drawing in the gas generated during the cleaning process through the air intake of the recovery pipe. After being treated by the filter screen and activated carbon adsorption layer, the gas is finally discharged into the carbon dioxide gas collection tank.

[0017] S3, Steam Cleaning and Drying Stage: After cleaning, the basket component continues to move forward into the second cleaning chamber of the cleaning and drying component. The steam cleaning mechanism is activated, and the steam generator draws water from the water tank through the pump to generate steam, which is then evenly sprayed onto the computer aluminum casing through the steam nozzle for deep cleaning.

[0018] After cleaning, the drying fan mechanism is started. At this time, the steam generated by the steam generator drives the steam turbine to rotate. The drive gear connected to the rotating shaft of the steam turbine rotates accordingly. Through belt drive, it drives the driven gear to rotate, which in turn drives the rotating shaft and rotating blades to rotate, generating hot air to dry the computer aluminum shell.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention integrates dry ice cleaning and steam cleaning technologies to efficiently remove stains, grease, and microburrs from the surface of computer aluminum casings. Dry ice cleaning utilizes the high-speed impact and low-temperature freezing properties of dry ice particles to achieve precise cleaning and deburring, while steam cleaning uses high-pressure, high-temperature steam for deep cleaning of the aluminum casing, ensuring effective cleaning. This invention also utilizes a portion of the steam generated by a steam generator to drive a steam turbine, which in turn drives the drying fan mechanism, achieving energy recycling and saving energy costs.

[0021] Furthermore, the gases generated during dry ice cleaning are recovered and treated by a gas recovery unit. After purification through a filter and activated carbon adsorption layer, they are finally discharged into a carbon dioxide gas collection tank, reducing the emission of harmful gases and meeting environmental protection requirements. At the same time, both dry ice cleaning and steam cleaning eliminate the need for chemical cleaning agents, reducing environmental pollution.

[0022] 2. This invention, through the insertion design of the basket component, can process multiple computer aluminum shells simultaneously, avoiding collisions between the shells and utilizing the gaps between them for efficient cleaning. The design of the limiting component and auxiliary wheel mechanism ensures the stability and angular stability of the computer aluminum shells during the cleaning process, further improving the cleaning quality. This invention has a simple structure, is easy to maintain, and reduces the labor intensity of operators. Attached Figure Description

[0031] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

Utilizing their high-speed impact and low-temperature freezing characteristics, they collide with the gap between the computer aluminum casing, which can not only effectively remove stains and grease from the surface of the aluminum casing, but also remove tiny burrs.

[0034] The gas recovery component 5 includes a recovery flue 51 disposed on one side of the first frame 41. One end of the recovery flue 51 is provided with an air intake, and a filter 52 is disposed on the air intake. A negative pressure air mechanism is disposed inside the filter 52. The negative pressure air mechanism is used to generate negative pressure to draw in gas. The negative pressure air mechanism includes a first motor 531, a fixing frame 532, and a fan 533. The first motor 531 is fixedly connected to the middle of the fixing frame 532. The output end of the first motor 531 is connected to the fan 533 to drive the fan 533 to rotate and generate negative pressure. The other end of the recovery flue 51 is connected to a carbon dioxide gas collection tank 54. The carbon dioxide gas collection tank 54 is used to collect the treated gas. An activated carbon adsorption layer is disposed in the middle of the recovery flue 51. The activated carbon adsorption layer is used to further purify the inhaled gas.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The cleaning and drying component 6 includes a second frame 61 disposed above the conveying component. A steam cleaning mechanism is disposed within the second frame 61. The steam cleaning mechanism is used to perform steam cleaning on the aluminum casing of the computer. A drying fan mechanism is disposed behind the steam cleaning mechanism. The drying fan mechanism is used to dry the cleaned aluminum casing of the computer. The steam cleaning mechanism includes a steam generator 62, a water tank 63, a pump, steam nozzles 64, and a steam turbine 65. The steam generator 62 is disposed on one side of the second frame 61. The steam generator 62 is used to generate high-pressure and high-temperature steam. One end of the steam generator 62 is connected to the water tank 63 through the pump. The other end of the steam generator 62 is connected to several steam nozzles 64 through a hose. Several sets of steam nozzles 64 are evenly disposed between the conveying rollers 2. One end of the steam generator 62 is connected to the steam turbine 65. A drive gear 664 is disposed at the rotating shaft end of the steam turbine 65.

[0036] The drying fan mechanism includes a fan housing 661, rotating blades 662, a rotating shaft 663, and a driven gear 665. Several sets of fan housings 661 are arranged above the second frame 61. The rotating shaft 663 passes through and is rotatably arranged within the several sets of fan housings 661. The rotating blades 662 are arranged outside the rotating shaft 663. A driven gear 665 is arranged at one end of the rotating shaft 663. The driving gear 664 and the driven gear 665 are connected by a belt 666. 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 belt 666, the driven gear 665 is driven to rotate, which in turn drives the rotating shaft 663 and the rotating blades 662 to rotate. The generated air is heated from the air outlet below the fan housing 661 and discharged in a concentrated manner to quickly dry the aluminum casing of the computer.

[0037] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 In this preferred embodiment, the placement basket component 3 includes a placement frame 31, multiple limiting blocks 32, and two handles 33. The placement frame 31 has a cavity inside. The multiple limiting blocks 32 are divided into two groups, and the two groups of limiting blocks 32 are symmetrically arranged on the top and bottom sides of the inner wall of the placement frame 31 to divide the cavity into multiple parts. The two handles 33 are symmetrically arranged on the top of the two side walls of the placement frame 31. 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 watermarks from collisions. The insertion type placement facilitates quick retrieval and is also conducive to the batch processing of computer aluminum shells, improving efficiency.

[0038] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7In a preferred embodiment, the limiting component includes limiting plates 71 symmetrically arranged on both sides inside the first frame 41 and the second frame 61. Several sets of auxiliary wheel mechanisms 72 are provided on the limiting plates 71. The auxiliary wheel mechanisms 72 are used to limit the movement range of the placement basket component 3 and to ensure the stability of the computer aluminum shell's angle during the cleaning process. Each auxiliary wheel mechanism 72 includes a sliding rod 721, a connecting rod 722, pulleys 723, and a spring 724. The sliding rods 721 are symmetrically slidably arranged at the upper and lower ends of the limiting plates 71. One end of the sliding rod 721 passes through the limiting plate 71, and the other end of the sliding rod 721 is connected to the connecting rod 722. A spring 724 is provided in the middle of the limiting plates 71 and the sliding rods 721 near the end of the connecting rod 722. Two sets of pulleys 723 are rotatably arranged on the outer side of the connecting rod 722. Two sets of limiting rods 34 are also provided on each side of the placement frame 31. The limiting rods 34 have grooves that correspond to the pulleys 723.

[0039] When the computer aluminum casing is placed in the placement basket component 3, it is conveyed by the conveyor rollers 2. When one end of the placement frame 31 begins to contact the auxiliary wheel mechanism 72, the pulley 723 contacts and slides with the groove on the limiting rod 34 of the placement frame 31. When the position of the placement frame 31 shifts, the pulley 723 drives the connecting rod 722 to be evenly stressed, pressing the sliding rod 721 backward. Under the action of the spring 724, the placement frame 31 is reset. The elastic support provided by the spring 724 allows the pulley 723 to have a certain range of motion within the groove, but at the same time, it can also provide sufficient resistance to prevent the placement basket component 3 from moving excessively during the cleaning process. This design ensures that the stability and angle of the computer aluminum casing remain unchanged during the cleaning process, maintaining the position and angle of the placement basket component for subsequent cleaning. This ensures that cleaning can be performed through the gaps between the computer aluminum casings, preventing uneven cleaning or damage caused by movement or tilting, and ensuring the stability of the computer aluminum casing during the cleaning process.

[0040] The above-mentioned cleaning device for computer aluminum casing processing is used in the following steps:

[0041] S1. Preparation stage: Insert the aluminum computer case to be cleaned into the placement frame 31 of the placement basket component 3, use the limit block 32 to ensure the aluminum case is stable, start the conveying component through the electrical control box 1, so that the placement basket component 3 together with the aluminum computer case inside it moves forward along the conveying roller 2.

[0042] S2, Dry Ice Cleaning Stage: When the basket component 3 enters the first cleaning chamber of the dry ice cleaning component 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 the 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 activated, and the gas generated during the cleaning process is drawn in through the air intake of the recovery smoke pipe 51. After the gas is treated by the filter screen 52 and the activated carbon adsorption layer, it is finally discharged into the carbon dioxide gas collection tank 54.

[0043] S3, Steam cleaning and drying stage: After cleaning, the basket component 3 continues to move forward into the second cleaning chamber of the cleaning and drying component 6. The steam cleaning mechanism is started, and the steam generator 62 draws water from the water tank 63 through the pump to generate steam and spray it evenly on the computer aluminum shell through the steam nozzle 64 for deep cleaning.

[0044] After cleaning, the drying fan mechanism is started. At this time, the steam generated by the steam generator 62 drives the steam turbine 65 to rotate. The drive gear 664 connected to the rotating shaft end of the steam turbine 65 rotates accordingly. Through the belt 666, the driven gear 665 is driven to rotate, which in turn drives the rotating shaft 663 and the rotating blades 662 to rotate, generating hot air to dry the computer aluminum shell.

[0045] In summary, this invention integrates dry ice cleaning and steam cleaning technologies to efficiently remove stains, grease, and microburrs from the surface of computer aluminum casings. Dry ice cleaning utilizes the high-speed impact and low-temperature freezing properties of dry ice particles to achieve precise cleaning and deburring, while steam cleaning uses high-pressure, high-temperature steam for deep cleaning of the aluminum casing, ensuring effective cleaning. This invention utilizes a portion of the steam generated by the steam generator 62 to drive the steam turbine 65, which in turn drives the drying fan mechanism, achieving energy recycling and saving energy costs.

[0046] Furthermore, the gas generated during dry ice cleaning is recovered and treated by the gas recovery component 5. After purification by the filter screen 52 and activated carbon adsorption layer, it is finally discharged into the carbon dioxide gas collection tank 54, reducing the emission of harmful gases and meeting environmental protection requirements. Simultaneously, both dry ice cleaning and steam cleaning eliminate the need for chemical cleaning agents, reducing environmental pollution. This invention, through the insert-type placement design of the basket component 3, can simultaneously process multiple computer aluminum shells, avoiding collisions and utilizing the gaps between the shells for efficient cleaning. The design of the limiting component and auxiliary wheel mechanism 72 ensures the stability and angular stability of the computer aluminum shells during the cleaning process, further improving cleaning quality. This invention has a simple structure, is easy to maintain, and reduces the labor intensity of operators.

The steam cleaning mechanism is started, and the steam generator (62) draws water from the water tank (63) through the pump to generate steam and spray it evenly on the computer aluminum shell through the steam nozzle (64) for deep cleaning. After cleaning, the drying fan mechanism is started. At this time, the steam generated by the steam generator (62) drives the steam turbine (65) to rotate. The drive gear (664) connected to the rotating shaft end of the steam turbine (65) rotates accordingly. Through the belt (666), the driven gear (665) is driven to rotate, which in turn drives the rotating shaft (663) and the rotating blades (662) to rotate, generating hot air to dry the computer aluminum shell.
