Abstract
Description
Technical Field
[0001] This invention relates to the field of ultrasonic cleaning machine technology, specifically an ultrasonic cleaning machine with high-efficiency cleaning function. Background Technology
[0002] As the cleanliness and consistency requirements for products such as hardware parts, precision machined parts, electronic structural components, and mold accessories continue to increase, ultrasonic cleaning equipment is gradually evolving from stand-alone and semi-manual models towards continuous and automated processes. Existing production lines generally aim to streamline processes such as loading, cleaning, rinsing / circulating filtration, drying, and unloading to reduce manual handling and the risk of secondary contamination, and improve cycle stability. Especially in batch processing scenarios, the cleaning process not only requires strong decontamination capabilities but also demands that different workpieces have similar postures, spacing, and ultrasonic treatment conditions within the cleaning area to achieve more controllable cleaning results and more stable process repeatability.
[0003] The common structure of existing ultrasonic cleaning machines includes an ultrasonic transducer / generator installed in the cleaning tank to generate a cavitation effect; a water supply pipeline, a circulation pump and a filter are used to form a cleaning fluid circulation to maintain the cleanliness of the liquid; thereby achieving the cleaning of the workpiece.
[0004] However, existing technologies still have significant shortcomings: First, common material distribution structures at the loading end often rely on fixed baffles, material distribution wheels, or simple vibration guides. During the conveying process, workpieces are prone to close contact, parallel interference, stacking, or jamming, resulting in uncontrollable spacing before entering the cleaning tank, which in turn causes local obstruction, collision, and uneven cleaning. Second, most equipment at the cleaning end uses a single-sided ultrasonic source structure, and the sound field distribution is significantly affected by the workpiece position, especially when the workpiece posture is inconsistent or the arrangement is unstable, which easily leads to cleaning blind spots. At the same time, some alignment or limiting schemes often lack effective contact feedback and position detection, which may cause workpieces to shift, overlap, or scatter in the tank, affecting the consistency of ultrasonic action. Third, common planar chains or mesh belts at the unloading end provide insufficient support, and the wet and slippery workpieces after cleaning are prone to rolling, shifting, or even falling during the conveying process. Therefore, those skilled in the art provide an ultrasonic cleaning machine with efficient cleaning function to solve the problems mentioned in the background. Summary of the Invention
[0005] The purpose of this invention is to provide an ultrasonic cleaner with high-efficiency cleaning function to solve the layering problem existing in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: The ultrasonic cleaning machine includes a feeding mechanism, an ultrasonic cleaning mechanism, and a discharging mechanism. The feeding mechanism is connected to the ultrasonic cleaning mechanism, and the discharging mechanism is also connected to the ultrasonic cleaning mechanism. The feeding mechanism includes a spacing component, a feeding component, and a feeding box assembly; The spacing component is installed on the feeding component, and the feeding component is installed on the feeding box assembly; The spacing assembly includes a spacing electromagnetic block, a spacing magnetic block, and a spacing elastic element. The magnetic poles of the spacing electromagnetic block and the spacing magnetic block repel each other, and the spacing elastic element is installed between the spacing electromagnetic block and the spacing magnetic block.
[0007] By adopting the above technical solution, the workpieces are first sequentially conveyed by the feeding mechanism and introduced into the ultrasonic cleaning mechanism. After cleaning in the ultrasonic cleaning mechanism, they are then orderly unloaded by the unloading mechanism, performing a linear continuous process. This reduces intermediate stops and manual intervention, forming a complete closed loop of feeding, cleaning, and unloading. This not only improves the automation level and operating efficiency of the entire machine but also effectively reduces the risk of workpieces getting stuck, misaligned, or contaminated during process switching, thereby improving the overall cleaning quality and equipment operating stability. The workpieces to be processed are first centrally accommodated in the feeding box assembly. After the feeding box assembly loads and initially guides the workpieces, the feeding component continuously conveys the workpieces and introduces them into the working area of the spacing component. Driven by the feeding component, the spacing component adjusts the relative position between the workpieces, ensuring that the spacing adjustment action is synchronized with the feeding and conveying action. The feeding box assembly provides a stable installation foundation and material storage space for both. This forms a collaborative working structure consisting of a loading box assembly for support, a loading component for conveying, and a spacing component for adjustment. The resulting integrated arrangement of loading, conveying, and spacing control ensures that workpieces are in an orderly and dispersed state before entering subsequent processing steps, reducing workpiece stacking and jamming, and improving the continuity, stability, and overall efficiency of the loading process. The spacing component sets the spacing electromagnetic block and the spacing magnetic block to a state of magnetic pole repulsion. By changing the current flowing through the spacing electromagnetic block, the magnetic force is altered, causing a controllable magnetic field change in the spacing electromagnetic block. This drives the spacing magnetic block to produce radial displacement. Under the elastic limiting and resetting action of the spacing elastic element, this displacement can form a periodic expansion and contraction motion, preventing jamming. This achieves dynamic adjustment of the spacing between workpieces entering the loading mechanism, avoiding stacking or sticking of workpieces during conveying, and improving the stability and consistency of subsequent conveying and cleaning.
[0008] The spacing assembly also includes a driven pulley, a conveyor belt, and a driven gear. The driven gear is mounted on the driven pulley, and the driven pulley and the conveyor belt are connected in a driving connection.
[0009] By adopting the above technical solution, the driven wheel is set as the transmission load-bearing component in the spacing assembly. The driven gear is fixedly installed on the driven wheel and maintains a synchronous rotation relationship with the driven wheel, so that when the driven gear is subjected to force and rotates, it can simultaneously drive the driven wheel to rotate. During the rotation, the continuous load-bearing and conveying of the workpiece is realized through the conveyor belt. At the same time, the driven gear rotates synchronously with the driven wheel and participates in the transmission cooperation within the spacing assembly, converting the rotational motion into the linear motion of the conveyor belt, and providing a stable motion basis for subsequent workpiece spacing adjustment.
[0010] The feeding assembly includes a drive box, a flush wheel, a drive sprocket, and a drive chain. The drive box and the drive sprocket are connected by a drive mechanism, the drive sprocket and the drive chain are connected by a drive mechanism, and the drive sprocket and the flush wheel are connected by a drive mechanism.
[0011] By adopting the above technical solution, when the drive box is started, the drive sprocket first rotates under the action of the drive box. The drive sprocket drives the drive chain to circulate through the transmission cooperation with the drive chain, thereby generating a continuous conveying effect on the workpiece. At the same time, the drive sprocket synchronously transmits the rotational power to the leveling wheel, so that the leveling wheel corrects the posture of the workpiece during the conveying process. The rotational power output by the drive box is simultaneously distributed to the two functional units of conveying and leveling, so that the workpiece can be adjusted to a uniform height or posture through the rolling contact of the leveling wheel during the conveying process of the drive chain. The effect achieved is that the workpiece arrangement can be automatically sorted while completing the feeding and conveying, reducing the phenomenon of workpiece tilting, misalignment or stacking, improving the stability and continuity of the feeding process, and providing the input conditions of workpieces with consistent posture and orderly arrangement for the subsequent cleaning process.
[0012] The feeding box assembly includes a feeding box body, an inclined frame, a vibrator, and a sliding inclined plate. The inclined frame is installed on the feeding box body, the vibrator is installed on the sliding inclined plate, and the sliding inclined plate is slidably installed on the feeding box body.
[0013] By adopting the above technical solution, the workpiece is first stacked in the feeding box and gradually moves towards the inclined frame under the inclination angle provided by the sliding inclined plate. At the same time, the vibrator works to make the sliding inclined plate vibrate slightly, thereby prompting the workpiece to overcome static friction and slide in a dispersed manner along the sliding inclined plate. The gravitational force generated by the sliding inclined plate and the vibration applied by the vibrator work together to make the sliding inclined plate form an orderly sliding feeding state in the feeding box, thereby realizing continuous guidance of the workpiece. The effect achieved is to effectively avoid the accumulation, jamming or bridging of workpieces in the feeding box, so that the workpiece enters the feeding assembly in a stable and uniform state, improving the continuity, reliability and overall work efficiency of the feeding process.
[0014] The tilting frame is equipped with a sliding groove. The flush wheel and the drive sprocket are rotatably connected to the tilting frame. The driven wheel and the sliding groove are slidably connected. The drive chain and the driven gear are connected by transmission. The tilting frame is tilted and connected to the ultrasonic cleaning mechanism.
[0015] By adopting the above technical solution, when the drive sprocket drives the drive chain, the power is transmitted to the driven gear through the drive chain and drives the driven wheel to rotate. During the rotation, the driven wheel is guided by the sliding groove and slides along the direction of the inclined frame. At the same time, the flush wheel rotates synchronously on the same inclined frame to adjust the posture of the conveyed workpiece. Since the inclined frame is set at an angle, after the workpiece is adjusted and conveyed, it naturally moves downward under the action of gravity and enters the ultrasonic cleaning mechanism connected to the inclined frame. By constraining the motion trajectory of the driven wheel through the sliding groove, the rotational motion and linear displacement are coupled. Combined with the tilt angle of the inclined frame, the power transmission, position adjustment and material guidance are coordinated. This achieves a smooth transition of the workpiece in the loading stage and automatic introduction into the ultrasonic cleaning mechanism, reduces intermediate jamming and material jumping, and improves the continuity and reliability of the whole machine operation.
[0016] The magnetic block with spacing is equipped with a transmission column, which abuts against the sliding inclined plate and is slidably connected to the feeding box.
[0017] By adopting the above technical solution, when the spacing magnetic block is displaced under the action of magnetic force, the transmission column moves along the sliding direction of the feeding box and applies or releases the pushing force to the sliding inclined plate by abutting against it, so that the sliding inclined plate can slide and adjust accordingly in the feeding box.
[0018] The vibrator has a guide surface that tapers towards the conveyor belt.
[0019] By adopting the above technical solution, when the vibrator operates and applies vibration to the components it is installed on, the workpiece located on the guide surface gradually converges towards the central area along the tapering guide surface under the combined influence of vibration and gravity, and is guided to the side facing the conveyor belt, eventually smoothly entering the effective conveying position of the conveyor belt. The vibration excitation generated by the vibrator keeps the workpiece in a low-friction motion state, while the geometric limiting and directional guiding effect formed by the tapering guide surface transforms the disordered motion of the workpiece into directional movement. The effect achieved is to effectively prevent the workpiece from scattering or shifting to both sides during vibration, so that the workpiece can automatically converge and be directionally introduced before entering the conveyor belt, improving the orderliness and conveying stability of the feeding process, and providing continuous and uniform workpiece input conditions for subsequent processes.
[0020] The ultrasonic cleaning system includes an ultrasonic cleaning tank, an inlet pipe, a circulation pump, a drain valve, a filter, a homogenizing component, an ultrasonic generator, a lifting hydraulic cylinder, and a reflector. The inlet pipe, circulation pump, and drain valve are all connected to the ultrasonic cleaning tank. The filter is located at the top of the ultrasonic cleaning tank, the circulation pump is located on one side of the ultrasonic cleaning tank, and the drain valve is located at the bottom of the ultrasonic cleaning tank. The inlet pipe is located at the bottom of the ultrasonic cleaning tank, away from the circulation pump, and is higher than the drain valve. The homogenizing component is mounted on the ultrasonic cleaning tank. The lifting hydraulic cylinder is securely connected to the ultrasonic cleaning tank and is also connected to the reflector via a drive mechanism. There are two sets of ultrasonic generators: one set is securely connected to the ultrasonic cleaning tank, and the other set is securely connected to the reflector. The reflector has a hemispherical reflecting area.
[0021] By adopting the above technical solution, the cleaning fluid enters the ultrasonic cleaning tank through the inlet pipe, and is driven by the circulation pump to form a circulating flow and is purified by the filter. The workpiece is simultaneously subjected to ultrasonic waves from one side of the ultrasonic cleaning tank and the other side of the reflector in the ultrasonic cleaning tank. The reflective area reflects and enhances the ultrasonic waves. If necessary, the position of the reflector is adjusted by the lifting hydraulic cylinder to change the ultrasonic field distribution. After cleaning, impurities are discharged through the drain valve. Its working principle is to combine liquid circulation, bidirectional ultrasonic excitation and hemispherical reflective structure to form an ultrasonic cleaning environment with a wider coverage and more uniform energy distribution. The effect achieved is to significantly improve the uniformity of ultrasonic cavitation and cleaning efficiency, reduce cleaning dead zones and energy attenuation, and at the same time realize the recycling of cleaning fluid and effective discharge of impurities, thereby improving the overall cleaning quality, stability and service life of the ultrasonic cleaning mechanism.
[0022] The uniform assembly includes a pressure-sensitive sheet, an infrared sensor, a rotating motor, and a uniform shielding plate. The rotating motor is fixedly connected to the ultrasonic cleaning tank, the infrared sensor is fixedly connected to the ultrasonic cleaning tank, the pressure-sensitive sheet and the uniform shielding plate are fixedly connected, the pressure-sensitive sheet and the infrared sensor are both electrically connected to the rotating motor, and the rotating motor and the uniform shielding plate are connected by a drive.
[0023] By adopting the above technical solution, when the workpiece is detected to be out of the preset alignment position, the position signal is transmitted to the rotating motor. The rotating motor drives the uniform baffle to rotate and guide or limit the workpiece. During the contact between the uniform baffle and the workpiece, the pressure sensor senses the contact pressure in real time and feeds back the signal to the rotating motor, so that the rotating motor adjusts the rotation amplitude of the uniform baffle or stops rotating according to the pressure change. The infrared sensor detects the workpiece position deviation, the rotating motor drives the uniform baffle to mechanically guide and limit the workpiece, and the pressure sensor provides feedback control of the contact state, thus forming a closed-loop workpiece alignment adjustment process. The effect achieved is that the workpiece entering the ultrasonic cleaning tank can be automatically adjusted to the preset alignment position without relying on manual intervention, avoiding workpiece tilting, overlapping or misalignment, thereby improving the consistency of workpiece arrangement and the stability of cleaning effect during the cleaning process.
[0024] The feeding mechanism includes a feeding chain, a dryer, and a feeding motor. The feeding motor is fastened to the ultrasonic cleaning tank, and the feeding chain is driven by the feeding motor. The dryer is fastened to the ultrasonic cleaning tank. The dryer is located above the feeding chain, and the feeding chain is concave in shape with higher sides.
[0025] By adopting the above technical solution, the workpiece for ultrasonic cleaning enters the feeding chain from the ultrasonic cleaning tank. Then, driven by the feeding motor, the torque is transmitted to the feeding chain, causing the feeding chain to rotate and transport downstream. At the same time, the dryer located above the feeding chain continuously dries the workpiece during transport, so that the workpiece can complete the removal of moisture simultaneously during movement. Furthermore, the concave feeding chain effectively prevents the workpiece from rolling, falling, or shifting position during the feeding process, improving the stability of the feeding process and the uniformity of drying, and enhancing the automation level and production efficiency of the entire machine.
[0026] Compared with the prior art, the beneficial effects of the present invention are: The feeding mechanism is equipped with a spacing component consisting of a spacing electromagnetic block, a spacing magnetic block, and a spacing elastic element. This component is mechanically linked with the driven wheel, driven gear, and conveyor belt. The magnetic repulsion generated by the spacing electromagnetic block is converted into controllable reciprocating motion under the limiting and resetting action of the spacing elastic element, thus periodically separating the workpieces on the conveyor belt. Simultaneously, the drive box is synchronously driven by the drive sprocket, drive chain, and flush wheel. During transport, the workpieces automatically adjust their posture through rolling contact with the flush wheel, avoiding workpiece stacking, parallel interference, and posture disorder. An ultrasonic generator is installed within the ultrasonic cleaning tank, both fixed to the tank and a reflector. The reflector's hemispherical reflective area performs multi-directional reflection of the ultrasonic waves, creating a superimposed sound field distribution in the cleaning fluid. Furthermore, a lifting hydraulic cylinder adjusts the relative position of the reflector and the workpiece, working in conjunction with a uniform component consisting of a rotating motor, a uniform shielding plate, an infrared sensor, and a pressure sensor to mechanically limit and correct the position of the workpieces entering the cleaning tank. This structure ensures that the workpiece remains stably aligned during the cleaning process and is placed within a high-energy-density and evenly distributed cavitation area, reducing the generation of cleaning blind spots. The unloading mechanism is fastened to the unloading motor and the ultrasonic cleaning tank, driving a concave unloading chain belt that is high on both sides and low in the middle. This allows the cleaned workpiece to be naturally centered and supported by the structure on both sides during the output process, effectively preventing rolling and displacement. At the same time, the dryer is fixedly set above the unloading chain belt, allowing the workpiece to be dried synchronously within the chain belt conveyor path, reducing process change structures and improving overall output stability.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example: Figure 1 - Figure 10 As shown, the present invention provides a technical solution: an ultrasonic cleaner with high-efficiency cleaning function. The ultrasonic cleaning machine includes a feeding mechanism 1, an ultrasonic cleaning mechanism 2, and a discharging mechanism 3. The feeding mechanism 1 and the ultrasonic cleaning mechanism 2 are connected, and the discharging mechanism 3 and the ultrasonic cleaning mechanism 2 are connected. The feeding mechanism 1 includes a spacing component 11, a feeding component 12, and a feeding box assembly 13; The spacing component 11 is mounted on the feeding component 12, and the feeding component 12 is mounted on the feeding box assembly 13; The spacing assembly 11 includes a spacing electromagnetic block 111, a spacing magnetic block 112, and a spacing elastic element 113. The magnetic poles of the spacing electromagnetic block 111 and the spacing magnetic block 112 repel each other, and the spacing elastic element 113 is installed between the spacing electromagnetic block 111 and the spacing magnetic block 112.
[0031] By adopting the above technical solution, the workpieces are first sequentially conveyed by the feeding mechanism 1 and introduced into the ultrasonic cleaning mechanism 2. After cleaning in the ultrasonic cleaning mechanism 2, they are then orderly unloaded by the unloading mechanism 3, performing a linear continuous process. This reduces intermediate stops and manual intervention, forming a complete closed loop of feeding, cleaning, and unloading. This not only improves the automation level and operating efficiency of the entire machine but also effectively reduces the risk of workpieces getting stuck, misaligned, or contaminated during process switching, thereby improving the overall cleaning quality and equipment operating stability. The workpieces to be processed are first centrally accommodated in the feeding box group 13. After the feeding box group 13 carries and initially guides the workpieces, the feeding component 12 continuously conveys the workpieces and introduces them into the working area of the spacing component 11. The spacing component 11, driven by the feeding component 12, adjusts the relative position between the workpieces, keeping the spacing adjustment action synchronized with the feeding and conveying action. The feeding box group 13 provides a stable installation foundation and material storage space for both, thus forming a complete closed loop. The feeding box assembly 13 carries the workpiece, the feeding component 12 conveys it, and the spacing component 11 adjusts it. This achieves an integrated arrangement of feeding, conveying, and spacing control, ensuring that the workpieces are in an orderly and dispersed state before entering subsequent processing steps. This reduces workpiece stacking and jamming, and improves the continuity, stability, and overall efficiency of the feeding process. The spacing component 11 sets the spacing electromagnetic block 111 and the spacing magnetic block 112 to a state of magnetic pole repulsion. By changing the current flowing through the spacing electromagnetic block 111, the magnetic force is changed, resulting in a controllable change in the magnetic field of the spacing electromagnetic block 111. This drives the spacing magnetic block 112 to produce radial displacement. Under the elastic limiting and resetting action of the spacing elastic element 113, this displacement can form a periodic expansion and contraction motion, preventing jamming. This achieves dynamic adjustment of the spacing between workpieces entering the feeding mechanism 1, avoiding stacking or sticking of workpieces during conveying, and improving the stability and consistency of subsequent conveying and cleaning.
[0032] The spacing assembly 11 also includes a driven wheel 114, a conveyor belt 115, and a driven gear 116. The driven gear 116 is mounted on the driven wheel 114, and the driven wheel 114 and the conveyor belt 115 are connected in a driving connection.
[0033] By adopting the above technical solution, the driven wheel 114 is set as the transmission load-bearing component in the spacing assembly 11, and the driven gear 116 is fixedly installed on the driven wheel 114 and maintains a synchronous rotation relationship with the driven wheel 114, so that when the driven gear 116 is subjected to force and rotates, it can simultaneously drive the driven wheel 114 to rotate. During the rotation, the continuous load-bearing and conveying of the workpiece is realized through the conveyor belt 115. At the same time, the driven gear 116 rotates synchronously with the driven wheel 114 and participates in the transmission cooperation within the spacing assembly 11, converting the rotational motion into the linear motion of the conveyor belt 115, and providing a stable motion basis for subsequent workpiece spacing adjustment.
[0034] The feeding assembly 12 includes a drive box 121, a flush wheel 122, a drive sprocket 123, and a drive chain 124. The drive box 121 and the drive sprocket 123 are connected by a drive mechanism, the drive sprocket 123 and the drive chain 124 are connected by a drive mechanism, and the drive sprocket 123 and the flush wheel 122 are connected by a drive mechanism.
[0035] By adopting the above technical solution, when the drive box 121 is started, the drive sprocket 123 first rotates under the action of the drive box 121. The drive sprocket 123 drives the drive chain 124 to circulate through the transmission cooperation with the drive chain 124, thereby generating a continuous conveying effect on the workpiece. At the same time, the drive sprocket 123 synchronously transmits the rotational power to the leveling wheel 122, so that the leveling wheel 122 corrects the posture of the workpiece during the conveying process. The rotational power output by the drive box 121 is simultaneously distributed to the two functional units of conveying and leveling, so that the workpiece can be adjusted to a uniform height or posture through the rolling contact of the leveling wheel 122 during the conveying process of the drive chain 124. The effect achieved is that the workpiece arrangement can be automatically sorted while the feeding and conveying is completed, reducing the phenomenon of workpiece tilting, misalignment or stacking, improving the stability and continuity of the feeding process, and providing the input conditions of workpieces with consistent posture and orderly arrangement for the subsequent cleaning process.
[0036] The feeding box assembly 13 includes a feeding box body 131, an inclined frame 132, a vibrator 133, and a sliding inclined plate 134. The inclined frame 132 is installed on the feeding box body 131, the vibrator 133 is installed on the sliding inclined plate 134, and the sliding inclined plate 134 is slidably installed on the feeding box body 131.
[0037] By adopting the above technical solution, the workpiece is first stacked in the feeding box 131, and gradually moves towards the inclined frame 132 under the action of the tilt angle provided by the sliding inclined plate 134. At the same time, the vibrator 133 works to make the sliding inclined plate 134 vibrate slightly, thereby prompting the workpiece to overcome static friction and slide in a dispersed manner along the direction of the sliding inclined plate 134. The gravitational component force generated by the sliding inclined plate 134 and the vibration action applied by the vibrator 133 cooperate with each other to make the sliding inclined plate 134 form an orderly sliding feeding state in the feeding box 131, thereby realizing the continuous guidance of the workpiece. The effect achieved is to effectively avoid the accumulation, jamming or bridging of workpieces in the feeding box 131, so that the workpiece enters the feeding assembly 12 in a stable and uniform state, improving the continuity, reliability and overall work efficiency of the feeding process.
[0038] The tilting frame 132 is provided with a sliding groove 1321. The flush wheel 122 and the drive sprocket 123 are rotatably connected to the tilting frame 132. The driven wheel 114 is slidably connected to the sliding groove 1321. The drive chain 124 and the driven gear 116 are connected in transmission. The tilting frame 132 is tilted and is connected to the ultrasonic cleaning mechanism 2.
[0039] By adopting the above technical solution, when the drive sprocket 123 drives the drive chain 124, the power is transmitted to the driven gear 116 through the drive chain 124 and drives the driven wheel 114 to rotate. During the rotation, the driven wheel 114 is guided by the sliding groove 1321 and slides along the direction of the inclined frame 132. At the same time, the flush wheel 122 rotates synchronously on the same inclined frame 132 to adjust the posture of the conveyed workpiece. Since the inclined frame 132 is inclined as a whole, after the workpiece is adjusted and conveyed, it naturally moves downward under the action of gravity and enters the ultrasonic cleaning mechanism 2 connected to the inclined frame 132. By constraining the motion trajectory of the driven wheel 114 through the sliding groove 1321, the rotational motion and linear displacement are coupled, and the tilt angle of the inclined frame 132 is combined to realize the coordination of power transmission, position adjustment and material guidance. This achieves a smooth transition of the workpiece in the loading stage and automatic introduction into the ultrasonic cleaning mechanism 2, reduces intermediate jamming and material jumping, and improves the continuity and reliability of the whole machine operation.
[0040] A transmission column 1121 is provided on the spacing magnetic block 112. The transmission column 1121 abuts against the sliding inclined plate 134, and the transmission column 1121 is slidably connected to the feeding box 131.
[0041] By adopting the above technical solution, when the spacing magnetic block 112 is displaced under the action of magnetic force, the transmission column 1121 moves along the sliding direction of the feeding box 131, and applies or releases the pushing force to the sliding inclined plate 134 by abutting against it, so that the sliding inclined plate 134 slides and adjusts accordingly in the feeding box 131.
[0042] The vibrator 133 is provided with a guide surface 1331, which is tapered and faces the conveyor belt 115.
[0043] By adopting the above technical solution, when the vibrator 133 operates and applies vibration to the components it is installed on, the workpiece located on the guide surface 1331 gradually converges towards the central area under the combined influence of vibration and gravity, and is guided to the side facing the conveyor belt 115, and finally smoothly enters the effective conveying position of the conveyor belt 115. The vibration excitation generated by the vibrator 133 keeps the workpiece in a low-friction motion state. At the same time, the geometric limit and directional guidance formed by the tapered guide surface 1331 transforms the disordered motion of the workpiece into directional movement. The effect achieved is to effectively prevent the workpiece from scattering or deviating to both sides during vibration, so that the workpiece can automatically converge and be directionally introduced before entering the conveyor belt 115, improve the orderliness and conveying stability of the feeding process, and provide continuous and uniform workpiece input conditions for subsequent processes.
[0044] The ultrasonic cleaning mechanism 2 includes an ultrasonic cleaning tank 21, an inlet pipe 22, a circulation pump 23, a drain valve 24, a filter 25, a homogenizing component 26, an ultrasonic generator 27, a lifting hydraulic cylinder 28, and a reflector 29. The inlet pipe 22 is connected to the ultrasonic cleaning tank 21, the circulation pump 23 is connected to the ultrasonic cleaning tank 21, the drain valve 24 is connected to the ultrasonic cleaning tank 21, the filter 25 is located at the upper end of the ultrasonic cleaning tank 21, the circulation pump 23 is located on one side of the ultrasonic cleaning tank 21, and the drain valve 24 is located at the bottom of the ultrasonic cleaning tank 21. The inlet pipe 26... 2 is located on the other side of the ultrasonic cleaning tank 21 away from the circulating pump 23. The water inlet pipe 22 is higher than the drain valve 24. The uniform component 26 is installed on the ultrasonic cleaning tank 21. The lifting hydraulic cylinder 28 is fastened to the ultrasonic cleaning tank 21. The lifting hydraulic cylinder 28 is drivenly connected to the reflector 29. There are two sets of ultrasonic generators 27. One set of ultrasonic generators 27 is fastened to the ultrasonic cleaning tank 21. The other set of ultrasonic generators 27 is fastened to the reflector 29. The reflector 29 has a reflection area 291, which is hemispherical.
[0045] By adopting the above technical solution, the cleaning fluid enters the ultrasonic cleaning tank 21 through the inlet pipe 22, and is driven by the circulation pump 23 to form a circulating flow and is purified by the filter 25. The workpiece is simultaneously subjected to ultrasonic waves from one side of the ultrasonic cleaning tank 21 and the other side of the reflector 29 in the ultrasonic cleaning tank 21. The reflection area 291 reflects and enhances the ultrasonic waves. If necessary, the position of the reflector 29 is adjusted by the lifting hydraulic cylinder 28 to change the ultrasonic field distribution. After cleaning, impurities are discharged through the drain valve 24. Its working principle is to combine liquid circulation, bidirectional ultrasonic excitation and hemispherical reflection structure to form an ultrasonic cleaning environment with a wider coverage and more uniform energy distribution. The effect achieved is to significantly improve the uniformity of ultrasonic cavitation and cleaning efficiency, reduce cleaning dead zones and energy attenuation, and realize the recycling of cleaning fluid and effective discharge of impurities, thereby improving the overall cleaning quality, stability and service life of the ultrasonic cleaning mechanism 2.
[0046] The uniformity component 26 includes a pressure-sensitive sheet 261, an infrared sensor 262, a rotating motor 263, and a uniformity shielding plate 264. The rotating motor 263 is fastened to the ultrasonic cleaning tank 21, the infrared sensor 262 is fastened to the ultrasonic cleaning tank 21, the pressure-sensitive sheet 261 and the uniformity shielding plate 264 are fastened to each other, the pressure-sensitive sheet 261 and the infrared sensor 262 are both electrically connected to the rotating motor 263, and the rotating motor 263 and the uniformity shielding plate 264 are connected by a drive.
[0047] By adopting the above technical solution, when the workpiece is detected to be out of the preset alignment position, the position signal is transmitted to the rotary motor 263. The rotary motor 263 drives the uniform shielding plate 264 to rotate and guide or limit the workpiece. During the contact between the uniform shielding plate 264 and the workpiece, the pressure sensor 261 senses the contact pressure in real time and feeds back the signal to the rotary motor 263, so that the rotary motor 263 adjusts the rotation amplitude of the uniform shielding plate 264 or stops rotating according to the pressure change. The infrared sensor 262 detects the workpiece position deviation. The rotary motor 263 drives the uniform shielding plate 264 to mechanically guide and limit the workpiece, and the pressure sensor 261 provides feedback control of the contact state, thus forming a closed-loop workpiece alignment adjustment process. The effect achieved is that the workpiece entering the ultrasonic cleaning tank 21 can be automatically adjusted to the preset alignment position without relying on manual intervention, avoiding workpiece tilting, overlapping or misalignment, thereby improving the consistency of workpiece arrangement and the stability of cleaning effect during the cleaning process.
[0048] The feeding mechanism 3 includes a feeding chain belt 31, a dryer 32 and a feeding motor 33. The feeding motor 33 is fastened to the ultrasonic cleaning tank 21 and is driven by the feeding chain belt 31. The dryer 32 is fastened to the ultrasonic cleaning tank 21 and is located above the feeding chain belt 31. The feeding chain belt 31 is concave in shape with high sides.
[0049] By adopting the above technical solution, the workpiece to be ultrasonically cleaned enters the feeding chain 31 from the ultrasonic cleaning tank 21. Then, driven by the feeding motor 33, the torque is transmitted to the feeding chain 31, causing the feeding chain 31 to rotate and be conveyed downstream. At the same time, the dryer 32 located above the feeding chain 31 continuously dries the workpiece being conveyed, so that the workpiece can complete the removal of moisture synchronously during the movement. Furthermore, the concave feeding chain 31 effectively prevents the workpiece from rolling, falling, or shifting position during the feeding process, improving the stability of the feeding process and the uniformity of drying, and enhancing the automation level and production efficiency of the whole machine.
[0050] The working principle of this invention is as follows: The workpiece to be processed is first placed into the loading box assembly 13, where it is centrally supported by the loading box 131. Under the action of the inclined structure formed by the inclined frame 132 and the sliding inclined plate 134, the workpiece generates a component of gravity. At the same time, the vibrator 133 drives the sliding inclined plate 134 to vibrate, so that the workpiece overcomes static friction and moves dispersedly along the direction of the sliding inclined plate 134. The guide surface 1331 on the vibrator 133 is tapered and is set towards the conveyor belt 115. Under the combined action of vibration and gravity, the workpiece is converged and guided, so that the workpiece enters the loading assembly 12 in an orderly state. After the drive box 121 is started, the drive chain 124 is driven by the drive sprocket 123 to run in a cycle, realizing continuous conveying of the workpiece. At the same time, the drive sprocket 123 is connected to the flush wheel 122, so that the workpiece is automatically corrected in posture through the rolling contact of the flush wheel 122 during the conveying process. After the workpiece enters the working area of the spacing component 11, the spacing electromagnetic block 111 generates a controllable magnetic field in the energized state, forming a magnetic pole repulsion transmission relationship with the spacing magnetic block 112. The spacing magnetic block 112 is displaced under the action of magnetic repulsion, and forms a periodic extension and retraction motion under the elastic limiting and resetting action of the spacing elastic element 113, thereby separating adjacent workpieces. During this process, the driven wheel 114 rotates under the transmission action of the driven gear 116 and the drive chain 124, and carries the workpiece forward through the conveyor belt 115. At the same time, the driven wheel 114 undergoes controlled sliding under the guidance of the sliding groove 1321 of the inclined frame 132, so that the rotational motion and linear displacement are coupled to achieve a stable transition. Subsequently, the workpiece enters the ultrasonic cleaning tank 21 connected to the inclined frame 132. During the cleaning stage, the cleaning fluid enters the ultrasonic cleaning tank 21 through the inlet pipe 22, is driven by the circulation pump 23 to form a circulating flow, and is purified by the filter 25. Two sets of ultrasonic generators 27, set on the ultrasonic cleaning tank 21 and the reflector 29, respectively emit ultrasonic waves into the cleaning fluid. The hemispherical reflective area 291 on the reflector 29 reflects and enhances the ultrasonic waves, forming a superimposed and uniformly distributed ultrasonic field in the cleaning tank. The infrared sensor 262 in the uniform component 26 detects the position of the workpiece, the rotating motor 263 drives the uniform shielding plate 264 to mechanically guide and limit the workpiece, and the pressure sensor 261 provides feedback on the contact state, thereby keeping the workpiece in a stable aligned state during the cleaning process. After cleaning, the workpiece is received by the feeding chain 31 and output under the drive of the feeding motor 33. The concave feeding chain 31 forms a self-limiting support for the workpiece, while the dryer 32 above it dries the workpiece synchronously, finally completing the cleaning operation.
