Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a workpiece cleaning structure for a feeding machine. Background Technology
[0002] Currently, in modern manufacturing, loading machines are widely used in stamping, injection molding, machining, assembly, and other processes. During processing, transportation, or storage, workpieces may have contaminants such as debris and dust adhering to their surfaces. If not cleaned in time, these debris may scratch the workpiece surface during precision machining, leading to a decline in processing quality. Therefore, the workpiece cleaning structure has become an important functional module of the loading machine, directly affecting production efficiency and product yield.
[0003] Currently, common cleaning methods involve simply blowing away debris with compressed air or using negative pressure adsorption. However, these methods struggle to thoroughly remove contaminants from hidden areas when dealing with workpieces with complex shapes, affecting the bonding performance and leading to assembly accuracy deviations. Therefore, a workpiece cleaning structure for the feeding machine needs to be designed to address these issues. Utility Model Content
[0004] This utility model provides a workpiece cleaning structure for a feeding machine to solve at least one of the above-mentioned technical problems.
[0005] The technical solution adopted by this utility model is as follows: a workpiece cleaning structure for a feeding machine, including a cleaning box, the cleaning box having a cleaning component and a collecting component, the cleaning component including a vent pipe and a rotating pipe connected to the vent pipe, the rotating pipe being connected to an exhaust component, the exhaust component including a flexible hose connected to the rotating pipe, a semi-circular slide rail and a nozzle, the nozzle being connected to the semi-circular slide rail via a movable slider, so that the position of the nozzle can be adjusted by the movement of the movable slider; the collecting component includes an air collecting component located below the cleaning component and a collecting box connected to the air collecting component, the inner wall of the air collecting component being an electrostatic adsorption plate.
[0006] In a preferred embodiment, the exhaust component further includes a spherical nozzle, which includes a spherical nozzle, a housing, and an adjuster for rotating the spherical nozzle.
[0007] In a preferred embodiment, at least two rotating pipes are provided and are symmetrically arranged in the cleaning chamber; multiple exhaust components are provided and are equidistantly arranged along the length direction of the rotating pipes.
[0008] In a preferred embodiment, the nozzle is provided with threads, and the movable slider is provided with a circular hole that matches the threads.
[0009] In a preferred embodiment, the nozzle is a Venturi nozzle, and an elastic element for sealing the Venturi nozzle is provided inside the circular hole.
[0010] In a preferred embodiment, the device further includes a placement assembly comprising a tray and a rotating shaft vertically fixed to the center of the bottom of the tray. The rotating shaft is connected to a drive mechanism, which drives the rotating shaft to rotate circumferentially to cause the tray to rotate around the central axis of the rotating shaft.
[0011] In a preferred embodiment, the air collecting component includes a conical air guide shroud and a centrifugal fan disposed above the collecting box, with the air inlet of the centrifugal fan connected to the small diameter portion of the conical air guide shroud.
[0012] In a preferred embodiment, the electrostatic adsorption plate includes an insulating substrate and a conductive layer disposed on the surface of the substrate.
[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0014] 1. In a preferred embodiment of this utility model, a flexible hose is used as the connecting medium between the air pipe and the nozzle. A semi-circular slide rail is used to adjust the airflow jet path. Specifically, by moving the slider, the nozzle moves along the semi-circular track, thereby changing the relative position and angle between the nozzle and the workpiece. Combined with the rotation of the rotating tube, all-round cleaning of the surface of workpieces of different shapes and sizes is achieved, ensuring that the airflow jet covers all parts of the workpiece, thus improving cleaning efficiency and effect.
[0015] 2. As a preferred embodiment of this utility model, the purpose of precise multi-directional airflow adjustment is achieved by setting a spherical nozzle on the exhaust component. Specifically, the spherical nozzle is driven to rotate inside the housing by the regulator, changing the direction and angle of gas injection. The flexible rotation of the spherical nozzle can precisely adjust the airflow trajectory for special parts such as complex curved surfaces of the workpiece, further improving the cleaning effect and efficiency.
[0016] 3. In a preferred embodiment of this utility model, high-pressure gas is evenly distributed to both sides of the cleaning chamber through at least two symmetrically arranged rotating pipes, avoiding differences in cleaning effect caused by uneven air supply pressure on one side. Multiple exhaust components equidistantly distributed along the length of the rotating pipes can simultaneously blow air onto the workpiece surface at multiple points, forming a comprehensive airflow cleaning area. This design achieves three-dimensional, dead-angle-free cleaning of the workpiece surface, significantly improving cleaning efficiency and uniformity.
[0017] 4. As a preferred embodiment of this utility model, the nozzle and the movable slider are detachably and securely connected by the meshing between the external thread of the nozzle and the internal thread of the circular hole of the movable slider. This ensures that the nozzle will not loosen or fall off under the reaction force generated by the high-pressure gas jet. At the same time, the characteristics of the threaded connection make the nozzle easy to disassemble and replace. This design improves the flexibility and practicality of the nozzle.
[0018] In addition, the Venturi nozzle uses a special contraction-expansion structure to accelerate high-pressure gas as it flows through the nozzle and generate a negative pressure effect, which enhances the airflow's entrainment capacity and thus improves cleaning efficiency. The elastic element inside the circular hole fits tightly against the outer wall of the nozzle, forming a sealing barrier to avoid a decrease in cleaning effect and energy waste due to leakage.
[0019] 5. As a preferred embodiment of this utility model, the rotating shaft is driven to rotate circumferentially by the driving mechanism, so that the tray and the workpiece placed on it rotate around the central axis of the rotating shaft. During the cleaning process, the rotating tray can expose different surfaces of the workpiece to the high-pressure airflow sprayed by the exhaust component in sequence, effectively solving the problem of cleaning blind spots for workpieces with complex shapes, forming a three-dimensional cleaning mode, and greatly improving cleaning efficiency and cleaning quality.
[0020] 6. In a preferred embodiment of this utility model, the special geometric structure of the conical guide shroud is used to gather and guide the impurities and airflow blown down by the cleaning components, concentrating them at the small-diameter opening. The centrifugal fan generates negative pressure through high-speed rotation, creating suction at the small-diameter opening of the conical guide shroud. This suction draws most of the particulate impurities gathered by the conical guide shroud into the collection box under the influence of gravity, improving cleaning efficiency and ensuring effective collection of impurities.
[0021] 7. As a preferred embodiment of this utility model, the electrostatic adsorption plate utilizes the electrostatic field generated by the conductive layer on the insulating substrate to charge the microparticles. The charged particles are adsorbed onto the surface of the conductive layer under the action of the electric field force, thereby achieving efficient capture of microparticles, solving the problem of fine dust residue, avoiding secondary re-entrainment of impurities, and ensuring the cleanliness of the clean environment and the efficient operation of the system.

[0042] Example 1
[0043] A preferred embodiment, such as Figures 1-3As shown, a workpiece cleaning structure for a feeding machine is described. When the workpiece to be cleaned is conveyed to the designated station of the feeding machine, the workpiece is positioned below the exhaust fan 23. Simultaneously, the ventilation pipe 21 in the cleaning assembly 2 is connected to an external air source to provide high-pressure gas to the device. The high-pressure gas generated by the external air source is delivered to the ventilation pipe 21 and evenly distributed to two symmetrically arranged rotating pipes 22. The rotating pipes 22 can adjust their angle according to actual needs, ensuring stable and even gas distribution to the exhaust fans 23, which are equidistantly arranged along their length. Simultaneously, the angle of the exhaust fans 23 relative to the workpiece is initially adjusted. Subsequently, the high-pressure gas in the rotating pipes 22 is delivered to the exhaust fans 23. For long, strip-shaped workpieces, the exhaust fans 23 distributed along the rotating pipes 22 can simultaneously cover the entire length of the workpiece. The exhaust fans 23 can adjust their angle in real time according to the workpiece's surface curvature, grooves, and other characteristics, allowing the airflow to be precisely sprayed to various parts, quickly removing surface impurities. Specifically, when the external air source is activated, the high-pressure gas enters the flexible hose 235 through the rotating pipe 22. Because the flexible hose... The flexibility of the nozzle 235 allows gas to be smoothly delivered to the nozzle 232. The moving slider 233 begins to move along the semi-circular slide rail 231, driving the nozzle 232 to move along a preset trajectory. Simultaneously, the rotating tube 22 rotates synchronously, causing the jet airflow from the nozzle 232 to spirally cover the workpiece surface. For irregularly shaped workpieces, the slider can move according to a pre-planned complex trajectory, ensuring that the nozzle 232 can reach all cleaning areas and perform all-round, no-dead-angle high-pressure gas blowing on the workpiece surface, blowing away dust, debris, and other impurities attached to the surface. The impurities blown off by the nozzle 232 move downward with the airflow under the push of the high-pressure gas. Since the air collecting component 31 of the collecting component 3 is located below the cleaning component 2, it guides the airflow and impurities to flow towards the collecting box 32.
[0044] Example 2
[0045] like Figure 4 and Figure 5 As shown, a workpiece cleaning structure for a feeding machine differs from Embodiment 1. High-pressure gas generated externally flows through a ventilation pipe 21 and a rotating pipe 22 into a spherical nozzle 2341 within a spherical nozzle 234. The rotating pipe 22 adjusts its angle as needed. When the workpiece to be cleaned reaches the designated station of the feeding machine, the regulator 2343 rotates the spherical nozzle 2341, ensuring the airflow is always perpendicular to the workpiece surface, enhancing the cleaning effect. When encountering grooves on the workpiece, the regulator 2343 quickly rotates the spherical nozzle 2341, precisely guiding the airflow into the groove to remove impurities. By adjusting the angle of the spherical nozzle 2341 within the housing 2342 using the regulator 2343, the nozzle 232 is positioned in a suitable spray posture for aiming at the workpiece. The nozzle 232 performs all-around blowing on the workpiece surface, thoroughly removing dust and other impurities.
[0046] Example 3
[0047] like Figure 6 As shown, a workpiece cleaning structure for a feeding machine, differing from Embodiment 1, aligns the threaded end 2321 of the nozzle 232 with the circular hole 2331 on the movable slider 233, gradually engaging the external thread 2321 of the nozzle 232 with the internal thread 2321 of the circular hole 2331 of the movable slider 233. The nozzle 232 is continuously rotated until tightened, ensuring its secure fixation on the movable slider 233 and preventing loosening due to airflow impact or slider movement during subsequent cleaning. When the movable slider 233 moves along the semi-circular slide rail 231, the nozzle 232 maintains its relative position during movement due to the stable connection of the threaded 2321, ensuring that high-pressure gas is sprayed at a preset angle and direction, effectively removing impurities from the workpiece surface. When the nozzle 232 needs replacement, it is removed from the movable slider 233, completing the replacement and maintenance of the nozzle 232, restoring the cleaning structure to its optimal working condition for continued cleaning operations.
[0048] In addition, the nozzle 232 can be a Venturi nozzle 232. High-pressure gas generated by an external air source flows into the Venturi nozzle 232 through the air pipe 21 and the rotating pipe 22. When the gas enters the constriction section of the nozzle 232, the flow velocity increases, reaching the highest flow velocity and generating negative pressure at the throat. Subsequently, the flow velocity decreases and the pressure rises in the expansion section, forming a high-speed airflow with strong entrainment capacity that is ejected from the nozzle 232. At the same time, an elastic element 2332 for sealing the Venturi nozzle 232 is provided inside the circular hole 2331. When the threaded end 2321 of the Venturi nozzle 232 is aligned with the circular hole 2331 of the movable slider 233, the nozzle 232 passes through the elastic element 2332 first. Rotate the nozzle 232 slowly clockwise. As the thread 2321 gradually engages, the elastic element 2332 is gradually squeezed and deformed until it is fully compressed. A reliable sealing layer is formed in the connection gap between the nozzle 232 and the moving slider 233, effectively preventing high-pressure gas leakage. Due to the sealing effect of the elastic element 2332, the gas is transmitted within the sealed channel throughout the cleaning process, ensuring that the cleaning effect is not affected by leakage.
[0049] Example 4
[0050] like Figure 7As shown, a workpiece cleaning structure for a loading machine, different from embodiment 1, also includes a placement component 4. The placement component 4 includes a tray 41 and a rotating shaft 42 vertically fixed to the center of the bottom of the tray 41. The loading machine transports the tray 41, on which the workpiece to be cleaned is placed, to a designated workstation inside the cleaning chamber 1, ensuring that the tray 41 is within the effective cleaning range of the exhaust component 23 and the nozzle 232. The groove on the tray 41 matches the shape of the workpiece, thereby further fixing the workpiece and preventing it from shifting or falling during rotation, ensuring the safety and stability of the cleaning process. At the same time, the rotating shaft 42 is connected to the drive mechanism 43, which drives the rotating shaft 42 to rotate circumferentially, thereby causing the tray 41 to rotate around the central axis of the rotating shaft 42. Specifically, the drive mechanism 43 drives the rotating shaft 42 to rotate circumferentially, and the rotating shaft 42 drives the tray 41 to rotate synchronously. The workpiece on the tray 41 then rotates around the central axis of the rotating shaft 42. Meanwhile, according to the surface characteristics of the workpiece, during the rotation of the workpiece, each surface of the exhaust component 23 passes through the spray area of the nozzle 232 in sequence, thereby achieving all-round, no-dead-angle cleaning of the workpiece.
[0051] Example 5
[0052] like Figure 2 and Figure 8 As shown, a workpiece cleaning structure for a feeding machine differs from Embodiment 1. When the exhaust component 23 in the cleaning assembly 2 sprays high-pressure airflow to sweep the workpiece surface, the dust, debris, and other impurities blown away diffuse with the airflow. At this time, the conical guide 311 located below the cleaning assembly 2 comes into play. Its large-diameter upward design can receive the diffused airflow containing impurities over a large area. Due to the special shape of the conical guide 311, the airflow gradually converges towards the small-diameter area during the flow process, and the impurities are also guided and concentrated, creating conditions for subsequent collection. At the same time, after the centrifugal fan 312 starts, the impeller rotates at high speed. The small-diameter area of the conical guide 311 is connected to the suction port 313 of the centrifugal fan 312. Under the action of negative pressure suction, the airflow containing impurities that converges in the conical guide 311 is quickly sucked into the centrifugal fan 312. Centrifugal fan 312 pressurizes the airflow, and impurities move with the airflow. Some larger particles of impurities settle naturally under the action of gravity. The airflow containing impurities enters the collection box 32, realizing the transfer from the clean area to the collection area.
[0053] In addition, such as Figure 8As shown, the electrostatic adsorption plate 33 includes an insulating substrate 331 and a conductive layer 332 disposed on the surface of the substrate. After initial collection by the centrifugal fan 312, the remaining finer dust particles in the cleaning box are adsorbed onto the electrostatic adsorption plate 33 due to the electrostatic field of the electrostatic adsorption plate 33. Specifically, when dust particles enter the electrostatic field, they become charged due to electric field induction or ion collision. Under the action of the electric field force, the charged dust particles overcome the airflow resistance and move towards the surface of the conductive layer 332, and are finally adsorbed onto the conductive layer 332. Even micron-sized or even nano-sized fine particles can be effectively captured, further purifying the airflow.
