Description

Technical Field

[0001] This application relates to the technical field of cleaning devices, and in particular to a non-contact high-pressure cyclone surface particle removal device. Background Technology

[0002] Non-contact high-pressure cyclone surface particle removal technology is an advanced dry cleaning process designed specifically for the precision manufacturing industry. Its core lies in utilizing the principles of fluid mechanics and electrostatics to achieve efficient peeling and removal of micron- or even nano-sized contaminants without touching the surface of the object. Through the built-in ion emission system and the electrostatic charge on the object surface, the strong adsorption state of tiny particles caused by van der Waals forces is released. High-pressure clean air, after rigorous filtration, is transformed into a high-speed rotating cyclone or high-frequency pulsating airflow through a specially designed spiral nozzle or vortex generator. This rotating airflow generates powerful shearing force and micro-vibration upon contact with the surface, enabling it to penetrate deep into micro-grooves and sweep away stubbornly attached dust, fibers, and foreign objects from the substrate, suspending them in the airflow. For example, the cyclone surface cleaning device with an externally located dirt chamber, as described in application number CN200880113799.8, uses the centrifugal force generated by the high-speed rotating airflow to throw dust out of the air (cyclone separation), supplemented by a collision plate to enhance the capture of fine particles, and multi-stage filtration to ensure clean exhaust.

[0003] However, the aforementioned existing technologies mainly rely on negative pressure suction when performing non-contact cyclone cleaning. The airflow sucks away loose or larger particles from the surface, but in order to cover a large area (such as a carpet), the airflow is a divergent turbulent flow that cannot be focused. There is a layer of still air on the surface of the object, and the speed and shape of the airflow cannot effectively penetrate this boundary layer to contact the micro-dust at the bottom. It is impossible to transfer energy to the micro-dust attachment point without contacting the surface. Moreover, the divergent airflow can easily blow dust into the surrounding clean area, causing secondary pollution.

[0004] Based on this, and given the above viewpoints, there is still room for improvement in existing technologies for non-contact cyclone cleaning methods. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a non-contact high-pressure cyclone surface particle removal device, employing the following technical solution: A non-contact high-pressure cyclone surface particle removal device includes a tray with a hinged cover that can be flipped to close the tray. A cyclone cleaning chamber is formed between the tray and the cover. A cyclone separator is provided on the tray and located in the cyclone cleaning chamber. The cyclone separator is used to guide the airflow to form a spiral centripetal flow in the cyclone cleaning chamber. The cyclone separator includes a lower spiral ring inside the tray and an upper spiral ring inside the flip cover that corresponds to the lower spiral ring. The lower spiral ring and the upper spiral ring are arranged in a ring spiral layout with decreasing radius. The upper spiral ring and the lower spiral ring fit together to form a spiral channel, which is used to guide the airflow. The spiral channel is constructed from the outside to the inside as an air inlet and an air outlet. The upper end of the flip cover is equipped with an upper air outlet pipe located at the air outlet end of the spiral channel, and the tray is equipped with a lower air outlet pipe corresponding to the air outlet end of the spiral channel.

[0006] Preferably, the flip cover is provided with an air intake part corresponding to the air intake end of the spiral channel. The air intake part is used to deliver airflow from the air intake end into the spiral channel and change the airflow speed by adjusting the air intake angle. The air intake includes a turntable that rotates on the flip cover. The turntable passes through the flip cover and corresponds to the air intake end of the spiral channel. An inclined air intake pipe passes through the turntable and is inclined toward the air intake end of the spiral channel.

[0007] Preferably, the turntable is provided with an arc-shaped rack, and the flip cover is rotatably provided with a drive gear that meshes with the arc-shaped rack.

[0008] Preferably, the flip cover is in the shape of an upwardly convex cone, and the upper air outlet is located at the highest point of the cone; The bottom of the tray is concave and cone-shaped, with the lower air outlet located at the lowest point of the cone.

[0009] Preferably, both the upper and lower spiral rings are made of flexible material.

[0010] Preferably, a vibrating element is provided at the bottom of the tray, which is used to drive the tray to produce periodic vibration; The vibrating component includes a base support at the bottom of the tray, a toothed disc slidably mounted on the bottom of the base support, and a support disc rotatably mounted on the toothed disc, which is used to support the operation of the equipment. A transmission gear that meshes with a toothed disc is rotatably mounted on the support plate.

[0011] Preferably, an adjusting screw that is threadedly engaged with the gear plate is rotatably provided on the base, and the adjusting screw is used to drive the gear plate to the eccentric position of the base.

[0012] Preferably, the pallet includes an annular enclosure and a chassis that is slidably disposed within the annular enclosure; The lower air outlet pipe is rotatably connected to the chassis, and the support plate is slidably connected to the lower air outlet pipe through the bracket. The lower air outlet pipe is constructed with a reciprocating guide groove, and one end of the adjusting screw corresponds to the reciprocating guide groove.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention utilizes an upper and lower spiral ring in conjunction with the workpiece body, using the workpiece as a physical partition to simultaneously construct independent upper and lower channels within a closed cavity. High-pressure airflow synchronously forms a spiral centripetal flow within the dual channels, completing the cleaning of the upper and lower surfaces of the workpiece in one pass. This eliminates blind spots in cleaning, avoids the need for workpiece flipping, thereby improving cleaning efficiency and reducing the risk of secondary contamination.

[0014] 2. The spiral channel of this invention has a geometric configuration with a decreasing radius from the outside to the inside, which forces the airflow to accelerate and form centrifugal shear force and high-frequency pulsation effect. It can penetrate the static air boundary layer on the surface of the workpiece and peel off the adsorbed micron-sized particles, thus achieving non-contact powerful decontamination.

[0015] 3. This invention creates periodically arranged grooves on opposite sides of the spiral ring, causing local micro-vortices and turbulent pulsations when high-speed airflow passes through. These micro-vortices disrupt the stability of the laminar boundary layer, allowing the main airflow to directly contact the workpiece surface. This enhances the shearing and peeling ability against submicron-sized dust and electrostatically adsorbed particles, solving the problem of incomplete removal of stubborn micro-dust by smooth flow channels.

[0026] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0027] This application discloses a non-contact high-pressure cyclone surface particle removal device, which uses high-pressure airflow to generate spiral centripetal flow to remove surface particles in a non-contact manner, achieving efficient cleaning and adaptive dust removal.

[0028] Example 1: Combination Figure 1 and Figure 2 As shown, a non-contact high-pressure cyclone surface particle removal device includes a tray 1, a flip cover 2 hinged to the tray 1, the flip cover 2 can be flipped to cover the tray 1 to form a cyclone cleaning chamber 3, the cyclone cleaning chamber 3 is located between the tray 1 and the flip cover 2, and a cyclone separator 4 is provided on the tray 1 and located in the cyclone cleaning chamber 3, the cyclone separator 4 is used to guide the airflow to form a spiral centripetal flow in the cyclone cleaning chamber 3.

[0029] During operation, the precision workpiece to be cleaned is first placed on the tray 1. Then, the flip cover 2 is operated to flip around the hinge point and close to the tray 1, so that the flip cover 2 and the tray 1 are tightly fitted to form a closed or semi-closed vortex cleaning chamber 3. The vortex cleaning chamber 3 provides a controlled physical space for the cleaning process, preventing high-pressure airflow leakage and secondary entry of external contaminants.

[0030] When the cyclone separator 4 is started, the high-pressure clean air source is introduced into the cyclone cleaning chamber 3. The airflow is injected from the outer area of ​​the cyclone cleaning chamber 3 at an inclined tangential angle, forcing the airflow to closely follow the chamber wall and make high-speed circular motion. Then, a spiral high-speed airflow field (i.e. spiral centripetal flow) is formed in the cyclone cleaning chamber 3 from the outside to the inside. In this flow field, the airflow continuously converges towards the central axis during the rotation process, and at the same time, it moves downward along the axial direction to scour the surface of the workpiece.

[0031] During this process, the high-speed rotating airflow generates enormous centrifugal shear force and high-frequency pulsation effect, which can instantly penetrate the static air boundary layer on the surface of the workpiece and use fluid dynamics to forcibly peel off the firmly adsorbed dust and impurities, suspending them in the vortex.

[0032] Subsequently, the stripped dust and impurities follow the trajectory of the airflow and eventually converge at the center of the vortex cleaning chamber 3. After the airflow spirals inward and converges, it should be sucked away by negative pressure or guided to the exhaust pipe for discharge.

[0033] Combination Figure 2 and Figure 3 As shown, the cyclone separator 4 includes a lower spiral ring 41 disposed in the tray 1 and an upper spiral ring 42 disposed in the flip cover 2 corresponding to the lower spiral ring 41. The lower spiral ring 41 and the upper spiral ring 42 are arranged in a ring spiral layout with decreasing radius, gradually contracting from the outer periphery to the center.

[0034] When the flip cover 2 is closed, the upper spiral ring 42 and the lower spiral ring 41 correspond to each other and fit together to form a continuous, closed and stable spiral channel 43. That is, the upper spiral ring 42 and the lower spiral ring 41 fit together to form the spiral channel 43, which is used to guide and constrain the flow of air.

[0035] Both the upper spiral ring 42 and the lower spiral ring 41 are made of flexible materials (such as special silicone, fluororubber or polymer elastomer). During cleaning, the precision workpiece to be cleaned is placed on the upper spiral ring 42. After the flip cover 2 is closed, the upper spiral ring 42 will press tightly on the precision workpiece. In this closed state, the workpiece body acts as a physical partition, dividing the space between the upper spiral ring 42 and the lower spiral ring 41 into two independent and parallel flow channels, namely the upper channel located above the workpiece and the lower channel located below the workpiece.

[0036] The upper channel is formed by the upper spiral ring 42 and the upper surface of the workpiece, and the lower channel is formed by the lower spiral ring 41 and the lower surface of the workpiece; both the upper and lower channels converge in a spiral shape from the outer air inlet 44 to the central air outlet 45.

[0037] When the upper spiral ring 42 is pressing the workpiece, it can ensure the airtightness of the spiral channel 43, prevent airflow short circuit, and avoid rigid contact damage to the surface of the precision workpiece.

[0038] Airflow is injected into both the upper and lower channels simultaneously, forming a double-sided spiral centripetal airflow. When cleaning the workpiece, the airflow moves in a high-speed spiral motion along the upper surface of the workpiece in the upper channel. The centrifugal shear force and high-frequency pulsation effect generated instantly peel off the dust and impurities adsorbed on the upper surface of the workpiece. At the same time, the airflow moves in a synchronous high-speed spiral motion along the lower surface of the workpiece in the lower channel, efficiently removing dust and impurities from the lower surface of the workpiece. The peeled dust and impurities are suspended in the vortex of their respective channels and converge from the outside to the inside with the airflow.

[0039] One end of the outer region of the spiral channel 43 is constructed as the air inlet 44. The high-pressure clean airflow is injected tangentially from here and is immediately forced to be guided by the geometry of the spiral channel 43, and begins to make high-speed circular motion. As the channel radius decreases from the outside to the inside, the airflow speed is further accelerated when flowing through the spiral channel 43, forming a strong spiral high-speed airflow field from the outside to the inside. The central region of the spiral channel 43 is constructed as the air outlet 45, where the airflow that has completed the cleaning task converges. In other words, the spiral channel 43 is constructed from the outside to the inside as the air inlet 44 and the air outlet 45.

[0040] During operation, high-pressure clean airflow is injected tangentially from the outer air inlet 44 of the upper and lower channels respectively. Under the geometric constraints of the channels, the airflow moves in a high-speed spiral centripetal motion close to the upper and lower surfaces of the workpiece. During this process, the strong centrifugal shear force generated by the airflow simultaneously peels off the dust and impurities attached to the upper and lower surfaces of the workpiece, and suspends and encapsulates the impurities in the swirling flow, which then converges from the outside to the inside of the channel outlet 45.

[0041] To achieve efficient and directional discharge of pollutants, an upper air outlet pipe 46 is constructed on the upper end of the flip cover 2. The upper air outlet pipe 46 is directly connected to the air outlet end 45 of the upper channel and is specifically used to discharge airflow carrying dust and impurities from the upper surface of the workpiece upwards. At the same time, a lower air outlet pipe 47 is constructed on the tray 1. The upper air outlet pipe 46 corresponds to and is connected to the air outlet end 45 of the lower channel and is specifically used to discharge airflow carrying dust and impurities from the lower surface of the workpiece downwards. Through the independent cleaning of the upper and lower channels and the dual-outlet discharge operation mechanism, the upper and lower surfaces of the precision workpiece are cleaned synchronously and deeply without dead angles. It also effectively avoids cross-mixing or secondary sedimentation of pollutants from the upper and lower layers during the discharge process, ensuring cleaning purity and efficiency.

[0042] Combination Figure 4 As shown, the flip cover 2 is provided with an air intake 5 corresponding to the air intake end 44 of the spiral channel 43. The air intake 5 is used to transport airflow from the air intake end 44 into the spiral channel 43, and to change the airflow speed by adjusting the air intake angle.

[0043] The air intake 5 includes a turntable 51 mounted on the flip cover 2, which is rotatably embedded in the mounting hole on the side wall of the flip cover 2. The turntable 51 passes through the flip cover 2 and corresponds to the air intake end 44 of the spiral channel 43. The turntable 51 has a disc-shaped structure, and its axis is perpendicular to the surface of the flip cover 2 (or parallel to the radial direction of the spiral channel 43). A sealed bearing or O-ring is provided between the turntable 51 and the mounting hole of the flip cover 2 to ensure that no gas leakage occurs during high-speed rotation adjustment.

[0044] An inclined air inlet pipe 52 is installed on the turntable 51. The air inlet pipe 52 is inclined towards the air inlet end 44 of the spiral channel 43. The axis of the air inlet pipe 52 forms a fixed angle with the rotation plane of the turntable 51. The lower outlet of the air inlet pipe 52 directly faces the air inlet end 44 of the spiral channel 43, and its upper inlet is used to connect to an external high-pressure air source hose. Since the air inlet pipe 52 is fixed on the turntable 51, when the turntable 51 rotates, the air inlet pipe 52 rotates synchronously. Its outlet points to a conical surface drawn in the horizontal plane, thereby changing the tangential angle of the airflow entering the spiral channel 43.

[0045] An arc-shaped rack 53 is provided on the turntable 51. The tooth profile of the rack is distributed along the arc trajectory of the turntable 51, and its arc range covers the adjustment range required for the air intake angle. A drive gear 54 that meshes with the arc-shaped rack 53 is rotatably provided on the flip cover 2. When the external power source drives the drive gear 54 to rotate, the drive gear 54 pushes the arc-shaped rack 53 to move along the arc path through the meshing of the teeth. Since the arc-shaped rack 53 is fixed on the turntable 51, the movement of the rack directly drives the turntable 51 to reciprocate around its own axis.

[0046] In the initial state, when the drive gear 54 drives the turntable 51 to rotate to a certain angle, the outlet direction of the inclined air intake pipe 52 mainly points to the radial or axial center of the spiral channel 43; at this time, the injected airflow has a large axial velocity component and a small tangential velocity component, and the airflow mainly enters the channel in the form of pushing and sweeping, which is suitable for rapid dust removal or cleaning of loose floating dust.

[0047] When the drive gear 54 rotates in the opposite direction, causing the turntable 51 to rotate to another extreme angle, the outlet direction of the inclined intake pipe 52 gradually deflects, making its injection direction closer to the tangential direction of the spiral channel 43. At this time, the airflow generates a strong rotating vortex in the channel, producing a huge centrifugal shear force, which is suitable for peeling off stubborn particulate pollutants.

[0048] By controlling the rotation angle of the drive gear 54, the angle of the intake pipe 52 can be continuously adjusted steplessly, thereby finding the optimal balance between high thrust and high centrifugal force to meet the cleaning needs of different workpiece materials and contamination levels.

[0049] The overall outline of the flip cover 2 is a convex frustum or cone shape (i.e., a cone), with its top center being the geometric highest point of the entire device. At the highest point of the cone of the flip cover 2, an upper air outlet pipe 46 extends vertically upward. The air outlet pipe is directly connected to the central confluence area of ​​the internal spiral channel 43, which is used to collect and discharge the airflow carrying contaminants on the upper surface of the workpiece. The design of the conical inner wall allows the dust thrown out by centrifugal force to naturally slide upward along the conical surface and converge to the highest point under the lift of the airflow, greatly reducing the possibility of secondary dust settling.

[0050] The bottom profile of tray 1 is a concave frustum or cone (i.e., a right cone), with the center of its bottom being the lowest geometric point of the entire device. At the lowest point of the cone of tray 1, a lower air outlet pipe 47 extends vertically downward. The lower air outlet pipe 47 corresponds to the central confluence area of ​​the internal lower spiral channel 43, and is used to collect and discharge the airflow carrying contaminants on the lower surface of the workpiece. The concave cone bottom wall uses gravity to guide the peeled particles and heavier impurities to slide naturally to the discharge port at the lowest point, ensuring no dead corners in cleaning.

[0051] Example 2: Combination Figure 5 and Figure 6 As shown in Example 1, in a high-speed airflow over a smooth surface, a relatively static laminar boundary layer is formed close to the workpiece surface. This airflow acts like a protective film, hindering the direct impact of the external high-speed swirling flow on the attached particles, making it difficult to peel off the tiny particles.

[0052] In this embodiment, a number of grooves 55 are regularly arranged on the opposite sides of the upper spiral ring 42 and the lower spiral ring 41. The grooves 55 are periodically and uniformly arranged along the spiral length direction of the corresponding upper spiral ring 42 and lower spiral ring 41.

[0053] When the airflow passes through the periodic groove 55, local micro-vortices and turbulent pulsations are generated inside the groove 55. These micro-vortices continuously spray onto the workpiece surface and disrupt the laminar boundary layer, allowing the external high-energy airflow to directly contact the workpiece surface. This enhances the airflow's ability to shear and peel off submicron-sized dust and electrostatically adsorbed particles, solving the problem of traditional smooth flow channels not thoroughly cleaning stubborn micro-dust.

[0054] Example 3: Combination Figure 7 , Figure 8 and Figure 9 As shown, based on Embodiment 1 or Embodiment 2, a vibrating element 6 is provided at the bottom of the tray 1. The vibrating element 6 is used to drive the tray 1 to generate periodic vibration. When the vibrating element 6 drives the tray 1 to generate high-frequency periodic vibration, the workpiece will reciprocate at high speed. Due to inertial lag, the particles attached to the surface of the workpiece tend to maintain their original stationary or low-speed state, thereby generating instantaneous relative displacement with the surface of the workpiece.

[0055] Periodic vibration provides additional kinetic energy and disturbance to the particles remaining on the cone surface. The vibration waves can effectively break the agglomeration structure between particles and prevent bridging. At the same time, the tiny jumps generated by the vibration cause the particles to continuously change their contact points with the cone surface, reducing sliding friction resistance.

[0056] The vibrating component 6 includes a base 61 at the bottom of the tray 1, a toothed disc 62 slidably disposed at the bottom of the base 61, a support disc 63 rotatably mounted on the toothed disc 62, the support disc 63 being used to support the operation of the equipment; a transmission gear 64 rotatably disposed on the support disc 63 and meshing with the toothed disc 62; and an adjusting screw 65 rotatably disposed on the base 61 and threadedly engaged with the toothed disc 62, the adjusting screw 65 being used to drive the eccentric position of the toothed disc 62 and the base 61.

[0057] During operation, an external drive source rotates the transmission gear 64, which in turn drives the gear disk 62 to perform high-speed circular motion around the central axis of the support disk 63. Due to the preset position of the adjusting screw 65, the geometric center of the gear disk 62 does not coincide with the center of mass of the base 61, and there is an eccentricity between them. When the gear disk 62 rotates at high speed, the direction of the centrifugal force generated changes periodically with time. The periodically changing centrifugal force is transmitted to the base 61 through the sliding connection between the gear disk 62 and the base 61, thereby driving the tray 1 to produce periodic vibrations, where the mass of the gear disk 62 is and the angular velocity is .

[0058] When it is necessary to increase the vibration intensity, the operator or control system rotates the adjusting screw 65 to push the toothed disc 62 to slide radially outward along the base 61, thereby increasing the eccentricity. With the rotation speed (frequency) remaining unchanged, the centrifugal force is increased, and the vibration amplitude of the tray 1 increases accordingly. This is suitable for removing stubborn adhered particles or large impurities.

[0059] When it is necessary to reduce the vibration intensity, rotate the adjusting screw 65 in the opposite direction to pull the toothed disc 62 towards the center, reduce the eccentricity, or even adjust the eccentricity to zero (at which point the center of the toothed disc 62 coincides with the center of mass of the base 61), so that the vibration stops completely. This mode is suitable for cleaning micro-dust on precision and fragile workpieces or for equipment standby.

[0060] In addition, the pallet 1 includes an annular enclosure 11, which serves as the outer fixed frame of the pallet 1 and is rigidly connected to the equipment frame or the bottom support 61 of the aforementioned vibrating member 6. It is used to limit the movement boundary of the internal components and prevent contaminants from spilling out. The chassis 12 is slidably disposed inside the annular enclosure 11.

[0061] The lower air outlet pipe 47 is rotatably connected to the chassis 12, and the support plate 63 is slidably connected to the lower air outlet pipe 47 via a bracket. The lower air outlet pipe 47 is constructed with a reciprocating guide groove 66, and one end of the adjusting screw 65 corresponds to the reciprocating guide groove 66.

[0062] When the gear disk 62 rotates under power drive, its eccentric motion or specific transmission structure will drive the adjusting screw 65 to rotate synchronously (or the rotation is accompanied by axial feed). At this time, the end of the adjusting screw 65 acts as the active driving element, closely abutting against and embedding in the reciprocating guide groove 66 opened on the surface of the lower air outlet pipe 47. The rotational motion of the screw is forcibly converted into the reciprocating linear motion of the lower air outlet pipe 47 along the axial direction using the cam principle. The reciprocating motion in the vertical direction is then transmitted to the sliding chassis 12 through rigid connection or limit fit, forcing the chassis 12, which originally only slides on the horizontal plane, to produce a vertical following displacement (or a specific tilting swing).

[0063] During this process, the inner wall of the ring enclosure 11 constrains the horizontal degree of freedom of the chassis 12, while the lower exhaust pipe 47 drives the vertical degree of freedom of the chassis 12. The two combine to form a complex composite vibration trajectory. This vertical reciprocating output, which is ultimately formed by the rotation input through the guide groove, not only enhances the turning effect of the workpiece in three-dimensional space to eliminate cleaning dead corners, but also ensures that the relative position between the dust discharge channel (lower exhaust pipe 47) and the bearing surface (chassis 12) always maintains dynamic coupling, realizing the mechanical adaptive effect of the dust discharge port opening and closing synchronously or tracking with the movement of the chassis 12.

[0064] The implementation principle of this invention is as follows: Step 1: First, open the flip cover 2 and place the precision workpiece to be cleaned stably on the lower spiral ring 41 in the tray 1, or place it directly in the center of the base 12. Then, operate the flip cover 2 to flip around the hinge point and close it. The upper spiral ring 42 (made of flexible material) on the inner side of the flip cover 2 tightly presses against the upper surface of the workpiece under the action of gravity or locking mechanism. At this time, the workpiece acts as a physical partition, dividing the space between the upper and lower spiral rings 41 into independent upper and lower channels. The deformation of the flexible ring ensures the airtightness of the channel, effectively preventing airflow short-circuiting and creating a closed and independent flow channel environment for subsequent cyclone movement.

[0065] Step Two: Activate the external high-pressure clean air source. The airflow is injected tangentially into the outer air inlet end 44 of the upper and lower channels through the air inlet pipe 52. Under the geometric constraint of the spiral channel 43, the airflow adheres closely to the upper and lower surfaces of the workpiece and performs high-speed spiral motion. As the radius of motion decreases from the outside to the inside, the airflow velocity gradually increases. When the airflow flows through the periodic grooves 55 on the spiral ring, a micro-vortex effect is generated, effectively disrupting the laminar boundary layer. The centrifugal shear force and high-frequency pulsation effect generated by the high-speed rotating airflow instantly penetrate the static air layer on the workpiece surface, forcibly peeling off the firmly adsorbed micro-dust and suspending it in the vortex, achieving deep cleaning.

[0066] Step 3: An external power source drives the transmission gear 64, causing the gear disc 62 to rotate at high speed. Utilizing a preset eccentricity, the periodic centrifugal force generated by the gear disc 62 drives the base 61 and the entire tray 1 assembly to produce high-frequency horizontal reciprocating vibration. Simultaneously, the adjusting screw 65 rotates synchronously, its end sliding within the reciprocating guide groove 66 of the lower air outlet pipe 47, converting the rotational motion into the axial reciprocating linear motion of the lower air outlet pipe 47. This drives the chassis 12 to produce a following displacement oscillation in the vertical direction. The workpiece tumbles under the combined trajectory of horizontal vibration and vertical reciprocation, thoroughly eliminating cleaning dead angles. Regardless of how the chassis 12 tilts, the lower air outlet pipe 47 is always adjusted in real time through the linkage mechanism to ensure that the air intake accurately tracks the dynamic lowest dust accumulation point of the chassis 12, maintaining efficient connectivity of the dust exhaust channel.

[0067] Step 4: The airflow carrying dust and impurities converges from the periphery to the center under the action of spiral centripetal force. Dust on the upper surface is guided to the highest point (conical apex) of the flip cover 2, and dust on the lower surface is guided to the lowest point (inverted conical bottom) of the tray 1. The upper layer of dirty airflow is discharged upward (or sideways) through the upper air outlet 46, and the lower layer of dirty airflow is discharged downward through the lower air outlet 47. The dual-channel independent discharge design effectively avoids cross-contamination between the upper and lower surfaces. After the cleaning cycle is completed, the air source is turned off, the airflow stops, the residual dust settles and is completely discharged, then the vibration motor stops, the toothed disc 62 stops rotating, the flip cover 2 is opened, and the cleaned workpiece can be taken out.

[0068] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
