[0072] The following specific embodiments will further illustrate this application in conjunction with the above-described accompanying drawings. Detailed Implementation

[0073] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0074] It should be noted that when a component is considered to be "set on" another component, it can be set directly on the other component or there may be a middle component present at the same time.

[0075] Please see Figure 1 This application provides a cleaning device 100 for cleaning moisture and contaminants such as aluminum shavings from the hinge hole 201 of a laptop computer's top cover 200 (see Figure 4). The cleaning device 100 includes a base 10, a positioning component 20, a cleaning component 30, and a control unit 40. The positioning component 20 and the cleaning component 30 are disposed on the base 10, and the control unit 40 is disposed within the base 10. The control unit 40 is electrically connected to the positioning component 20 to position the top cover 200, and is also electrically connected to the cleaning component 30 to clean the hinge hole 201. In some embodiments of this application, the cleaning device 100 can also be used to clean mobile phone casings, desktop computer casings, or any other workpiece with holes. In other embodiments of this application, the control unit 40 may be omitted.

[0076] The cleaning device 100 provided in this application can achieve efficient positioning of the top cover 200 by setting the positioning component 20. By setting the cleaning component 30 and utilizing the exhaust function of the cleaning component 30, contaminants in the pivot hole 201 of the top cover 200 are blown off. The suction function of the cleaning component 30 is used to recover the blown-off contaminants, thereby achieving efficient cleaning of contaminants in the pivot hole 201 of the top cover 200. This is beneficial to improving the degree of automation and is less likely to damage the outer surface of the top cover 200, thus improving the appearance yield of the top cover 200. In other embodiments of this application, the cleaning device 100 can also be used to clean other workpieces, such as housings, mobile phone covers, camera lens mounts, and other workpieces with holes.

[0077] Please see Figure 1 The positioning component 20 includes a fixture 2 and a side-pushing mechanism 3. The fixture 2 has a limiting area 211. The side-pushing mechanism 3 is disposed on the side of the fixture 2. The side-pushing mechanism 3 is used to push the upper cover 200 (see Figure 4) from the side into the limiting area 211, thereby facilitating the cleaning component 30 to clean the rotating hole 201 (see Figure 4).

[0078] Please see Figure 2 and Figure 3 The cleaning assembly 30 includes an air intake mechanism 31, an exhaust mechanism 32, and a return air block 33. The air intake mechanism 31 and the exhaust mechanism 32 are connected to the return air block 33, which has a return air chamber 331. The exhaust mechanism 32 blows clean gas toward the rotating shaft hole 201. The clean gas enters the rotating shaft hole 201 to be cleaned and blows away moisture and aluminum shavings, becoming a contaminant-laden gas. This contaminant-laden gas flows back into the return air chamber 331. The air intake mechanism 31 draws the contaminant-laden gas from the return air chamber 331, thereby cleaning the moisture and aluminum shavings in the rotating shaft hole 201. The return air block 33 contains the contaminant-laden gas, preventing it from scattering. In some embodiments of this application, the return air block 33 can be replaced by a pipeline. In other embodiments of this application, the return air block 33 can be omitted.

[0079] Please see Figure 2 and Figure 3 In this embodiment, the cleaning component 30 further includes an actuation mechanism 34, which includes a slide cylinder 341, a first linear guide 342, a first slider 343, a second slider 344, a first elastic element 345, and two second elastic elements 346.

[0080] Please see Figure 2 and Figure 3The slide cylinder 341 includes a cylinder body 341a and a slide 341b that is drively connected to the cylinder body 341a. The cylinder body 341a drives the slide 341b to move relative to the cylinder body 341a. The cylinder body 341a is fixedly mounted on the base 10, and the slide 341b is movably mounted on the side of the cylinder body 341a away from the base 10. In some embodiments of this application, the slide cylinder 341 can be replaced by other first driving components (not shown), which can be any type such as an electric motor or an internal combustion engine.

[0081] Please see Figure 2 and Figure 3 The first linear guide 342 includes a linear guide body 342a and a linear guide block 342b disposed at one end of the linear guide body 342a. The linear guide body 342a is fixedly disposed on the side of the slide table 341b away from the machine base 10.

[0082] Please see Figure 2 and Figure 3 The first slider 343 and the second slider 344 are both slidably disposed on the linear guide body 342a. The first elastic member 345 is disposed between the first slider 343 and the linear guide stop 342b. The second elastic member 346 is disposed between the first slider 343 and the second slider 344. The air return block 33 is disposed on the second slider 344. The air return block 33 has two first openings 332 and one second opening 333. The two first openings 332 are disposed opposite to each other. The second opening 333 is disposed opposite to the first openings 332. The first openings 332 and the second opening 333 are both connected to the air return chamber 331.

[0083] Please see Figure 2 and Figure 3 The exhaust mechanism 32 includes a gas compression device (not shown), an air blowing needle 321, and an exhaust pipe (not shown) connecting the gas compression device and the air blowing needle 321. One end of the air blowing needle 321 is fixedly mounted on the first slider 343, and the other end of the air blowing needle 321 passes through two opposing first openings 332 and protrudes from the return air block 33. There is a gap S between the air blowing needle 321 and the first openings 332. The gas compression device is used to generate compressed clean gas, such as high-pressure nitrogen or high-pressure air. The high-pressure clean gas enters the air blowing needle 321 through the exhaust pipe, and then is sprayed at high speed from the end of the air blowing needle 321 into the rotating shaft hole 201 to be cleaned, becoming a contaminant-laden gas. The contaminant-laden gas flows into the return air chamber 331 through the gap S.

[0084] Please see Figure 2 and Figure 3 The suction mechanism 31 includes a vacuum generator (not shown), a suction nozzle 311, and a suction pipe (not shown) connecting the vacuum generator and the suction nozzle 311. The suction nozzle 311 is connected to the second opening 333. The vacuum generator is used to create a negative pressure, allowing the contaminated gas in the return air chamber 331 to enter the suction nozzle 311 through the second opening 333, then pass through the suction pipe, and be discharged after being filtered by the dust collection system.

[0085] Please see also Figure 3 , Figure 4A and Figure 4B In specific operation, the cylinder body 341a drives the slide 341b to move toward the fixture 2. The slide 341b drives the blowing needle 321, the suction nozzle 311 and the return block 33 mounted on it to also move toward the fixture 2. When the blowing needle 321 extends into the rotating shaft hole 201, the return block 33 abuts against the outside of the rotating shaft hole 201. The gap S communicates with the rotating shaft hole 201. At this time, the first elastic member 345 and the second elastic member 346 can buffer the collision between the return block 33 and the outside of the rotating shaft hole 201, reducing the deformation or misalignment caused by rigid collision. In this design, both the first elastic element 345 and the second elastic element 346 are compression springs, and the spring constant of the first elastic element 345 is less than the elastic constant of the second elastic element 346. That is, the first elastic element 345 is softer than the second elastic element 346. This allows the reverse force of the gas to overcome the elastic force of the first elastic element 345 when the air nozzle 321 sprays air into the pivot hole 201, thereby causing the air nozzle 321 to retract slightly. This allows for air cleaning of different areas within the pivot hole 201, especially for the pivot hole 201 with a stepped cross-section, achieving effective and high-quality cleaning.

[0086] Please see Figure 5 In this embodiment, the side-pushing mechanism 3 includes a base 21, a linear cylinder 22, a second linear guide 23, and a pusher assembly 24. The base 21 is disposed on one side of the fixture 2, the linear cylinder 22 and the second linear guide 23 are disposed on the base 21, and the pusher assembly 24 is movably disposed on the second linear guide 23. The linear cylinder 22 is throttle-connected to the pusher assembly 24 to push the pusher assembly 24 to push the upper cover 200 from the side. In some embodiments of this application, the linear cylinder 22 may also be replaced by a second driving member (not shown), which includes either an electric motor or an internal combustion engine.

[0087] Please see Figure 5 In this embodiment, the push block assembly 24 includes a third slider 241, a transmission connector 242, and a side push block 243. The third slider 241 is slidably mounted on the second linear guide 23, the transmission connector 242 is mounted on the third slider 241, and the side push block 243 is mounted on the transmission connector 242. The transmission connector 242 includes a connecting body 242a and a protrusion 242b mounted on the connecting body 242a. The protrusion 242b has a groove 242c that penetrates both opposite surfaces of the protrusion 242b. The linear cylinder 22 has a power output shaft 221 and a retaining ring 222 mounted on the end of the power output shaft 221. The end of the power output shaft 221 is movably accommodated in the groove 242c, and the retaining ring 222 abuts against the protrusion 242b, thereby ensuring stable power output and reducing jamming.

[0088] Please see Figure 5 In this embodiment, the side-pushing mechanism 3 further includes a third elastic element 26, which is disposed between the transmission connector 242 and the power output shaft 221. The third elastic element 26 is used to buffer the force exerted by the power output shaft 221 on the transmission connector 242.

[0089] Please see Figure 5 In this embodiment, the side push blocks 243 are symmetrically arranged at opposite ends of the transmission connector 242. The side push blocks 243 are generally cylindrical, and the arc-shaped side surfaces of the side push blocks 243 are used to push against the upper cover 200, so that the side push blocks 243 and the upper cover 200 are in approximately line-surface contact, thereby improving the accuracy of side push positioning and reducing wear on the upper cover.

[0090] Please see Figure 1 and Figure 6 In this embodiment, the positioning component 20 further includes a plurality of suction cups 25, and the fixture 2 is provided with a plurality of through holes 212. The through holes 212 are located within the limiting area 211, and the suction cups 25 are disposed within the through holes 212. The suction cups 25 are used to adsorb and fix the upper cover 200 from the bottom of the upper cover 200, thereby preventing the blowing needle 321 from aligning with the rotating shaft hole 201 during the blowing process.

[0091] Please see Figure 1 and Figure 6In this embodiment, the base 10 has a drawer structure. The base 10 includes an outer box 11 and an inner box 12. The outer box 11 is movably fitted onto the outside of the inner box 12. The positioning component 20 and the cleaning component 30 are disposed on the outer box 11, and the control unit 40 is disposed on the inner box 12. By designing the base 10 as a pull-out structure, space can be saved, and wiring and maintenance can be facilitated.

[0092] Please see Figure 1 and Figure 6 In this embodiment, the control unit 40 includes a control motherboard 41, two start buttons 42, and a timer 43. The start buttons 42 and the timer 43 are electrically connected to the control motherboard 41. The two start buttons 42 are spaced apart on the outer side of the inner box 12, and the timer 43 is positioned between the two start buttons 42. The control motherboard 41 is also electrically connected to the positioning component 20 and the cleaning component 30. Please refer to [further details omitted]. Figure 2 and Figure 1 In practical use, pressing both start buttons 42 simultaneously controls the side-pushing mechanism 3 to push the upper cover 200 to the predetermined limit area 211. Then, the air-blowing needle 321 blows air. The timer 43 controls the blowing duration of the air-blowing needle 321. When the preset duration is reached, the timer 43 controls the air-blowing needle 321 to stop blowing. By setting two spaced start buttons 42, the operator needs to use both hands, which increases the safety factor. The timer 43 can be used to adjust the blowing duration, thus facilitating the adjustment of the cleaning device 100 to achieve optimal cleaning conditions. The control motherboard 41 can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), etc.
