Description

Technical Field

[0001] This utility model relates to the field of computer chassis processing technology, specifically a computer chassis cleaning device. Background Technology

[0002] During the manufacturing process of computer chassis, metal shavings, oil stains, dust and other impurities remain on the chassis surface. These impurities not only affect the appearance quality of the chassis, but may also damage electronic components during subsequent assembly, reducing the reliability and lifespan of the product. Traditional cleaning methods, such as manual wiping and simple blowing, are inefficient and have unstable cleaning effects, making it difficult to meet the needs of large-scale industrial production.

[0003] The current methods for cleaning computer cases mostly involve workers brushing the cases after work. This method is inefficient and time-consuming, and is not suitable for cleaning large numbers of cases. Existing case cleaning devices may not clean thoroughly, and are unable to reach deep into crevices and holes to remove stubborn oil and impurities; the cleaning method is also limited. Utility Model Content

[0004] The purpose of this invention is to provide a computer chassis cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a computer chassis cleaning device, including a workbench, a surface pre-cleaning mechanism provided on the surface of the workbench, a deep cleaning mechanism provided on the surface of the workbench, and the deep cleaning mechanism including a chassis clamping and transport component and a deep cleaning component;

[0006] The deep cleaning component includes a cleaning box, and the chassis clamping and transport component includes a main frame. The cleaning box is fixedly connected to the left end of the workbench. A debris box is located at the right end inside the cleaning box. An ultrasonic generator is installed at the bottom of the cleaning box. A drain pump is installed at the bottom left end of the cleaning box, and a drain pipe is fixedly connected to the left end of the drain pump. A secondary cleaning water tank is fixedly connected to both the front and back of the cleaning box. An adjustable angle spray head is installed at the bottom inner end of the cleaning box. A water pump is fixedly connected to the bottom outer end of the cleaning box, and a water supply pipe is installed between the water pump and the secondary cleaning water tank. A debris removal guide plate is fixedly connected to the left end of the workbench. Before the chassis enters the cleaning box for cleaning, the workbench... Personnel add specialized cleaning agent to the cleaning tank, then the chassis enters the tank for cleaning. During the cleaning process, the ultrasonic generator operates, producing ultrasonic waves and high-frequency vibrations that cause strong cavitation of the cleaning agent molecules. This allows the cleaning agent molecules to penetrate deep into the gaps and holes of the chassis, removing stubborn oil and impurities. Simultaneously, a water pump draws water from the auxiliary cleaning tank and sprays it into the cleaning tank through adjustable-angle spray nozzles. This high-pressure spray from different angles further washes away any remaining impurities and cleaning agent after ultrasonic cleaning. This component combines multiple cleaning methods to quickly and thoroughly remove various impurities from the chassis surface, significantly improving cleaning efficiency compared to traditional methods.

[0007] Preferably, the chip box is designed as a detachable structure, and the end of the chip discharge guide plate away from the worktable is aligned with the top of the chip box.

[0008] Preferably, the chassis clamping and transport assembly includes a main frame, which is fixedly connected to the top left end of the workbench.

Mounting plates are fixedly connected to the front and rear ends of the right side of the inner end of the main frame. Infrared detection sensors are mounted on the surface of the mounting plates. When the chassis is transported to the main frame via a conveyor roller and conveyor belt, the infrared detection sensors detect the chassis's arrival and stop the conveyor rollers. At this time, the electrically controlled telescopic column and connecting arm move the clamping plate and adsorption clamping block to both sides of the chassis for clamping. A servo-controlled motor drives the screw to rotate, moving the deep cleaning mechanism to move the chassis into the cleaning chamber for cleaning. After cleaning, the chassis is transported to the outside for retrieval. This component enables fully automated chassis transport, eliminating the need for frequent manual handling by workers, reducing consumption, and enhancing cleaning efficiency.

During the cleaning process, an ultrasonic generator operates, producing ultrasonic waves and high-frequency vibrations. This causes strong cavitation of the cleaning agent molecules, allowing them to penetrate deep into the chassis's crevices and holes, removing stubborn oil and impurities. Simultaneously, a water pump draws water from the auxiliary cleaning tank and sprays it into the cleaning chamber through adjustable-angle spray nozzles. This high-pressure spray from different angles further washes away any remaining impurities and cleaning agent after ultrasonic cleaning. This component combines multiple cleaning methods to quickly and thoroughly remove various impurities from the chassis surface, significantly improving cleaning efficiency compared to traditional methods.

[0014] 2. This computer chassis cleaning device is equipped with a chassis clamping and transport component. When the chassis is transported to the main frame via the transfer rollers and conveyor belt, an infrared detection sensor will detect that the chassis has arrived and stop the transfer rollers.

Before the chassis enters the cleaning box 721 for cleaning... The staff adds a special cleaning agent to the cleaning tank 721, and then the chassis enters the cleaning tank 721 for cleaning. During the cleaning process, the ultrasonic generator 723 works to generate ultrasonic waves and high-frequency vibrations, which cause the cleaning agent molecules to generate a strong cavitation effect, thereby penetrating into the gaps and holes of the chassis and removing stubborn oil and impurities. At the same time, the water pump 728 works to draw water from the cleaning auxiliary water tank 726 and spray it into the cleaning tank 721 through the adjustable angle spray head 727, spraying the chassis with high pressure from different angles to further rinse away the impurities and cleaning agent remaining after ultrasonic cleaning.

Mounting plates 7111 are fixedly connected to the front and rear ends of the right inner side of the main frame 711. An infrared detection sensor 7112 is installed on the surface of the mounting plate 7111. When the chassis is transported to the main frame 711 via the transfer roller 3 and conveyor belt 4, the infrared detection sensor 7112 will detect that the chassis is in place and stop the transfer roller 3. At this time, the electrically controlled telescopic column 7103 and connecting arm 7105 will move the clamping plate 7106 and the suction clamp 7107 to both sides of the chassis for clamping, via a servo... The control motor 714 drives the screw 713 to rotate, which in turn moves the slider 717 to move the machine box into the cleaning box 721 for cleaning.

[0032] Example 2

[0033] Please see Figure 1-6Furthermore, based on Embodiment 1, the surface pre-cleaning mechanism 6 further includes a fixed frame 61, which is fixedly connected to the top right end of the workbench 1. The front and rear ends of the fixed frame 61 are rotatably connected to a rotating shaft 62. A detachable cleaning brush roller 63 is installed on the surface of the rotating shaft 62.

The surface of the workbench 1 is connected to the conveyor belt 4. The workbench 1 is equipped with the conveyor roller controller 5.

[0035] In actual operation, when this device is in use, the chassis is placed above the conveyor belt 4 and transported by the transmission roller 3, the conveyor belt 4 and the transmission roller controller 5. The chassis is pre-cleaned by the surface pre-cleaning mechanism 6. The rotating shaft 62 is driven by the servo motor 64 to rotate. The surface of the chassis is cleaned by the detachable cleaning brush roller 63. The detachable cleaning brush roller 63 is made of soft and wear-resistant material, which can remove tightly attached dust and dirt without damaging the surface of the chassis. The detachable cleaning brush roller 63 is driven by the servo motor 64 and can achieve forward and reverse rotation to enhance the cleaning effect. During the cleaning process, the air pump 69 works and uses the nozzle 68 to assist in cleaning the chassis. It can generate a strong airflow to blow off larger metal debris and dust on the surface of the chassis. These debris and impurities will move with the conveyor belt 4 and be guided by the chip guide plate 7201 to fall into the detachable chip box 722 for collection, which is convenient for later collection and processing.

[0036] When the chassis is transported to the main frame 711 via the transfer roller 3 and conveyor belt 4, the infrared detection sensor 7112 will detect that the chassis has arrived and stop the transfer roller 3 from working. At this time, the electrically controlled telescopic column 7103 and the connecting arm 7105 will move the clamping plate 7106 and the adsorption clamping block 7107 to both sides of the chassis for clamping. The servo control motor 714 drives the screw 713 to rotate and drive the slider 717 to move, moving the chassis into the cleaning box 721 for cleaning. After cleaning, the chassis is transported to the outside for retrieval. The setting of this component realizes the fully automatic transportation of the chassis, eliminating the need for workers to manually pick up and drop the chassis frequently for a long time, reducing consumption and enhancing cleaning efficiency. After the chassis is removed, the reset button 7109 can be pressed to reset the component, making it convenient to continue cleaning the next set of chassis.

[0037] Before the chassis enters the cleaning chamber 721 for cleaning, the staff adds a special cleaning agent to the inside of the cleaning chamber 721. Then, the chassis enters the cleaning chamber 721 for cleaning. During the cleaning process, the ultrasonic generator 723 works to generate ultrasonic waves and high-frequency vibrations, causing the cleaning agent molecules to produce a strong cavitation effect, thereby penetrating into the gaps and holes of the chassis to remove stubborn oil stains and impurities. At the same time, the water pump 728 works to draw water from the cleaning auxiliary water tank 726 and spray it into the cleaning chamber 721 through the adjustable angle spray head 727, spraying the chassis with high pressure from different angles to further rinse away the impurities and cleaning agent remaining after ultrasonic cleaning. This component combines multiple cleaning methods to quickly and thoroughly remove various impurities from the chassis surface, and the cleaning efficiency is significantly improved compared to traditional methods.
