Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to an ultrasonic cleaning production line. Background Technology

[0002] In traditional ultrasonic cleaning production lines, the cleaning, rinsing, and drying of workpieces are usually completed at different stations. The transfer of workpiece baskets between these stations mostly relies on simple linear movement and lifting. Relying solely on conventionally placed and fixed cleaning baskets makes it difficult to ensure that all parts of the workpiece are in full contact with the cleaning solution and rinsing water, and it is also not conducive to uniform heating during drying. After rinsing and before drying, water droplets are easily left on the surface of the workpiece, forming water stains after drying, which affects the appearance and performance of the product.

[0008] As a further improvement to the above technical solution, the vibration assembly includes a top plate, a bottom plate, a first elastic element, and a first cam mechanism. The fixed part of the vibration assembly is the top plate, which is fixedly connected to the movable part of the lifting assembly. The movable part of the vibration assembly is the bottom plate, which is disposed below the top plate and parallel to it. The first elastic element is disposed between the top plate and the bottom plate, and has a tendency to pull the bottom plate toward the top plate. The first cam mechanism is disposed at the bottom of the top plate and is connected to the gear set for transmission. The first cam mechanism is used to periodically push the bottom plate, causing it to move downward against the force of the first elastic element, and move upward under the restoring force of the first elastic element, thereby realizing the reciprocating vibration of the bottom plate relative to the top plate.

[0009] As a further improvement to the above technical solution, the first cam mechanism includes a first abutting block, a first rotating shaft, and a first cam body. The first rotating shaft is disposed at the bottom of the top plate and can rotate relative to the top plate. The first rotating shaft is connected to the gear set for transmission. The first cam body is sleeved on the first rotating shaft and is coaxially disposed with the first rotating shaft and rotates synchronously.

[0013] The beneficial effects of this invention are as follows: the frame provides a basic support structure; the first driving device drives the connecting frame to move along the first guide rail; the lifting assembly drives the cleaning basket to move up and down in the vertical direction, enabling the cleaning basket to accurately enter or leave different processing devices and realize the transfer between workstations; the vibration assembly drives the cleaning basket to reciprocate in the vertical direction, shaking off water droplets on the surface of the workpiece; the swing assembly drives the cleaning basket to swing back and forth around the horizontal axis, changing the position of the workpiece in the processing device; the transmission assembly converts the lifting motion of the lifting assembly into the vibration drive of the vibration assembly, realizing the synchronous operation of lifting and vibration. The oscillating component drives the cleaning basket to oscillate back and forth around the horizontal axis, changing the orientation of the workpiece in each processing unit. This avoids dead corners in cleaning and drying, ensuring that all parts of the workpiece are fully in contact with the cleaning solution and rinsing water, and that it is heated evenly during drying. The vibrating component drives the cleaning basket to vibrate back and forth in the vertical direction, shaking off water droplets adhering to the surface of the workpiece as it leaves and enters each processing unit, creating excellent conditions for subsequent drying and achieving spotless drying. The transmission component utilizes the relative motion between the moving part of the lifting component and the fixed second rack during lifting to drive the gear set to rotate, which in turn drives the moving part of the vibrating component to reciprocate. This converts the lifting motion into the vibration drive of the vibrating component, achieving synchronous operation of lifting and vibration, and improving the operating efficiency and stability of the equipment.

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0020] In traditional ultrasonic cleaning production lines, the cleaning, rinsing, and drying of workpieces are usually completed at different stations. The transfer of workpiece baskets between these stations mostly relies on simple linear movement and lifting. Relying solely on conventionally placed and fixed cleaning baskets makes it difficult to ensure that all parts of the workpiece are in full contact with the cleaning solution and rinsing water, and it is also not conducive to uniform heating during drying. After rinsing and before drying, water droplets are easily left on the surface of the workpiece, forming water stains after drying, which affects the appearance and performance of the product.

[0021] Therefore, this invention proposes an ultrasonic cleaning production line, referring to... Figures 1-3 It includes a frame 100, a cleaning basket 110 for placing workpieces, and an ultrasonic cleaning device 120, a rinsing device 130, and a drying device 140 arranged sequentially along one side of the frame 100 in a horizontal direction. It also includes a first guide rail 150, a first drive device 200, a connecting frame 300, a lifting assembly 400, a vibration assembly 500, a transmission assembly 600, and a swing assembly 700. The first drive device 200 is mounted on the frame 100, and the first guide rail 150 is arranged horizontally on the frame 100. The connecting frame 300 is disposed on the movable part of the first driving device 200, and the connecting frame 300 is slidably connected to the first guide rail 150; the fixed part of the lifting assembly 400 is disposed on the connecting frame 300, the fixed part of the vibration assembly 500 is disposed on the movable part of the lifting assembly 400, the fixed part of the swing assembly 700 is disposed on the movable part of the vibration assembly 500, and the washing basket 110 is disposed on the movable part of the swing assembly 700; the lifting assembly 400 is used to drive the... The cleaning basket 110 moves vertically up and down to sequentially enter or exit the ultrasonic cleaning device 120, rinsing device 130, and drying device 140; the vibration assembly 500 drives the cleaning basket 110 to reciprocate vertically; the swing assembly 700 drives the cleaning basket 110 to swing reciprocally around a horizontal axis; the transmission assembly 600 includes a second rack 610 and a gear set 620, the second rack 610 being vertically mounted on the fixed part of the lifting assembly 400, and the gear set 620... The gear set 620 is rotatably mounted on the fixed part of the vibration component 500. The gear set 620 is connected to the movable part of the vibration component 500. The second rack 610 meshes with the gear set 620. When the lifting component 400 drives its movable part to rise and fall, the fixed second rack 610 and the gear set 620 that moves with the movable part of the lifting component 400 generate relative motion, thereby driving the gear set 620 to rotate. In turn, the gear set 620 is driven to generate reciprocating vibration of the movable part of the vibration component 500 through the transmission connection.

[0022] The frame 100 provides a basic support structure; the first drive device 200 drives the connecting frame 300 to move along the first guide rail 150; the lifting component 400 drives the cleaning basket 110 to move up and down in the vertical direction, so that the cleaning basket 110 can accurately enter or leave different processing devices and realize the transfer between workstations; the vibration component 500 drives the cleaning basket 110 to reciprocate in the vertical direction to shake off water droplets on the surface of the workpiece; the swing component 700 drives the cleaning basket 110 to swing back and forth around the horizontal axis to change the position of the workpiece in the processing device; the transmission component 600 converts the lifting motion of the lifting component 400 into the vibration drive of the vibration component 500, realizing the synchronous operation of lifting and vibration. The oscillating component 700 drives the cleaning basket 110 to oscillate back and forth around the horizontal axis, changing the position of the workpiece in each processing device. This avoids dead corners in cleaning and drying, ensuring that all parts of the workpiece can fully contact the cleaning solution and rinsing water, and that it can be heated evenly during drying. The vibration component 500 drives the cleaning basket 110 to vibrate back and forth in the vertical direction, shaking off water droplets adhering to the surface of the workpiece when it leaves and enters each processing device, creating excellent conditions for subsequent drying and achieving spotless drying. The transmission component 600 uses the relative motion between the moving part of the lifting component 400 and the fixed second rack 610 during lifting to drive the gear set 620 to rotate, which in turn drives the moving part of the vibration component 500 to reciprocate. This converts the lifting motion into the vibration drive of the vibration component 500, realizing synchronous operation of lifting and vibration, and improving the operating efficiency and stability of the equipment.

[0023] During operation, the workpiece is placed in the cleaning basket 110. The first drive device 200 drives the connecting frame 300 to move along the first guide rail 150, bringing the cleaning basket 110 above the ultrasonic cleaning device 120. Then, the lifting assembly 400 drives the cleaning basket 110 to descend, allowing it to enter the ultrasonic cleaning device 120 for cleaning. During the cleaning process, the swing assembly 700 drives the cleaning basket 110 to swing back and forth around the horizontal axis to improve the cleaning effect. After cleaning, the lifting assembly 400 drives the cleaning basket 110 to rise and leave the ultrasonic cleaning device 120, and the first drive device 200 then moves the cleaning basket 110 to the rinsing device. Above 130, the lifting component 400 drives the cleaning basket 110 to descend into the rinsing device 130 for rinsing. Similarly, the swing component 700 can change the posture of the workpiece in the cleaning basket 110 to improve the rinsing effect. After rinsing, the lifting component 400 drives the cleaning basket 110 to rise, and the vibration component 500 drives the cleaning basket 110 to vibrate back and forth in the vertical direction to shake off water droplets on the surface of the workpiece. Then, the first driving device 200 moves the cleaning basket 110 above the drying device 140, and the lifting component 400 drives the cleaning basket 110 to descend into the drying device 140 for drying, thus completing the entire cleaning process.

[0024] During the horizontal movement of the cleaning basket 110, unstable phenomena such as shaking and swaying are prone to occur, which is not conducive to the continuous and stable operation of the entire production line. Therefore, in one embodiment, the first driving device 200 includes a first motor 210, a first rack 220, and a first gear. The first motor 210 is mounted on the connecting frame 300, the first rack 220 is mounted on the frame 100 and is parallel to the first guide rail 150, and the first gear is coaxially mounted with the driving end of the first motor 210 and rotates synchronously. The first gear meshes with the first rack 220. By driving the first gear with the first motor 210 to mesh with the first rack 220 mounted on the frame 100, more precise linear motion control can be achieved, allowing the cleaning basket 110 to accurately reach the corresponding ultrasonic cleaning, rinsing, drying, and other workstations, ensuring that each process is carried out smoothly in sequence and avoiding the impact of positional deviation on the cleaning, rinsing, and drying effects. The gear and rack transmission method ensures smooth movement and reduces shaking and deviation of the cleaning basket 110 during movement.

[0025] In the event of a power outage or machine shutdown, the cleaning basket 110 may fall due to gravity, posing a safety hazard. Therefore, in one embodiment, the lifting assembly 400 includes a lead screw shaft 410, a lead screw nut 420, and a second motor 430. The second motor 430 is mounted on the connecting frame 300. The lead screw shaft 410 is vertically mounted on the connecting frame 300 and can rotate relative to the connecting frame 300. The lead screw shaft 410 is coaxially mounted with the drive end of the second motor 430 and rotates synchronously. The lead screw nut 420 is threadedly connected to the lead screw shaft 410 and is fixedly connected to the fixing part of the vibration assembly 500. The threaded drive between the lead screw shaft 410 and the lead screw nut 420 has a precise transmission ratio, enabling precise vertical positioning of the cleaning basket 110 and ensuring its accurate entry into the designated positions of the ultrasonic cleaning device 120, rinsing device 130, or drying device 140, thus guaranteeing the effectiveness of each process. The threaded engagement between the lead screw nut 420 and the lead screw shaft 410 has a self-locking characteristic, allowing the cleaning basket 110 to remain stably at its current height when the second motor 430 stops working, eliminating the need for an additional braking device, saving costs and improving safety.

[0026] Relying solely on the transmission between the lead screw shaft 410 and the lead screw nut 420, the cleaning basket 110 is prone to swaying and tilting when lifting a heavy cleaning basket 110 or after prolonged use. Therefore, in one embodiment, the lifting assembly 400 further includes an auxiliary shaft 440 and a slider 450. The auxiliary shaft 440 is mounted on the connecting frame 300 and is parallel to the lead screw shaft 410. The slider 450 is slidably connected to the auxiliary shaft 440 and is fixed to the lead screw nut 420 or the fixing part of the vibration assembly 500. The cooperation between the auxiliary shaft 440 and the slider 450 provides additional guiding support for the lifting assembly 400, which can limit its displacement in the non-vertical direction and effectively avoid the shaking and tilting of the cleaning basket 110 caused by slight eccentricity or uneven force during the lead screw drive process, making the entire lifting process more stable and reliable. The weight of the cleaning basket 110 and related components will generate a large axial force on the lead screw assembly. The auxiliary shaft 440 can share some of the axial force generated during the lifting process, reduce the lateral force borne by the lead screw shaft 410, extend the service life of the lead screw assembly, and reduce the maintenance cost of the equipment.

[0027] Water droplets on the workpiece surface are difficult to remove completely, and water stains easily form after drying, affecting the product's appearance and performance. Therefore, in one embodiment, the vibration assembly 500 includes a top plate 510, a bottom plate 520, a first elastic element 530, and a first cam mechanism 540. The fixed part of the vibration assembly 500 is the top plate 510, which is fixedly connected to the movable part of the lifting assembly 400. The movable part of the vibration assembly 500 is the bottom plate 520, which is disposed below and parallel to the top plate 510. The first elastic element 530 is disposed between the top plate 510 and the bottom plate 520. During this period, the first elastic member 530 has a tendency to pull the bottom plate 520 toward the top plate 510. The first cam mechanism 540 is disposed at the bottom of the top plate 510 and is connected to the gear set 620 for transmission. The first cam mechanism 540 is used to periodically push the bottom plate 520, so that it moves downward against the force of the first elastic member 530 and moves upward under the restoring force of the first elastic member 530, thereby realizing the reciprocating vibration of the bottom plate 520 relative to the top plate 510. The reciprocating vibration of the base plate 520 forces water droplets adhering to the workpiece surface to fall off, improving dehydration efficiency compared to natural dripping and creating ideal conditions for subsequent drying, effectively preventing water stains. The first cam mechanism 540 is connected to the gear set 620, and the vibration can be driven by the movement of the lifting component 400, eliminating the need for an additional independent power source, simplifying the equipment structure, and reducing energy consumption and failure rate. With the cooperation of the first elastic element 530 and the first cam mechanism 540, a regular and stable reciprocating vibration can be formed. The amplitude and frequency can be precisely controlled through the cam design to adapt to the dehydration needs of different workpieces. Specifically, the first elastic element 530 is a tension spring, with its upper and lower ends connected to the top plate 510 and the base plate 520 respectively. The tension spring is always in a stretched state, providing continuous restoring tension to the base plate 520.

[0028] During power transmission, instability such as jamming or interruption may occur, causing irregular vibration of the base plate 520 and affecting the vibration effect. Therefore, in one embodiment, the first cam mechanism 540 includes a first abutment block 541, a first rotating shaft 542, and a first cam body 543. The first rotating shaft 542 is disposed at the bottom of the top plate 510 and can rotate relative to the top plate 510. The first rotating shaft 542 is connected to the gear set 620 for transmission. The first cam body 543 is sleeved on the first rotating shaft 542 and is coaxially disposed with the first rotating shaft 542 and rotates synchronously. The first abutment block 541 is disposed on the top surface of the base plate 520, and the outline of the first cam body 543 periodically abuts against the top surface of the first abutment block 541. The first cam body 543, driven by the first rotating shaft 542, performs uniform circular motion. The periodic changes in its contour cause intermittent contact and disengagement with the first abutment block 541 during rotation. When contacting, it pushes the first abutment block 541 and the base plate 520 downward; when disengaging, the elastic restoring force of the first elastic element 530 causes the base plate 520 to return to its original position. Through this continuous cyclic process, the rotational motion transmitted from the first rotating shaft 542 is converted into the reciprocating linear motion of the base plate 520, thereby achieving the vibration function. Furthermore, the frequency and amplitude of the vibration are precisely controlled by the contour design of the cam body and the rotational speed of the first rotating shaft 542.

[0029] A single gear drive makes it difficult to precisely adjust the vibration frequency according to the characteristics of the workpiece, which may lead to incomplete dehydration or damage to the workpiece due to improper frequency. Therefore, in one embodiment, the gear set 620 includes a second gear 621, a third gear 622, and a fourth gear 623. The second gear 621 is mounted on the top plate 510 and can rotate relative to the top plate 510. The second gear 621 meshes with the second rack 610. The third gear 622 is mounted on the top plate 510 and can rotate relative to the top plate 510. The second gear 621 meshes with the third gear 622. The fourth gear 623 is sleeved on the first rotating shaft 542 and is coaxially arranged with the first rotating shaft 542 and rotates synchronously. The fourth gear 623 meshes with the third gear 622. Through the sequential meshing of the second gear 621, the third gear 622, and the fourth gear 623, the rotational power generated by the relative motion between the second rack 610 and the lifting assembly 400 can be stably transmitted to the first cam mechanism 540, resulting in high transmission efficiency and low power loss. By designing gear sets 620 with different numbers of teeth, the transmission ratio can be precisely adjusted, thereby controlling the rotational speed of the first cam mechanism 540 and enabling flexible adjustment of the vibration frequency of the vibration assembly 500 to adapt to the dewatering requirements of different workpieces. The meshing of multiple gears can change the direction of power transmission, so that the vertical relative motion of the second rack 610 is ultimately converted into the horizontal axial rotation of the first rotating shaft 542, meeting the requirements of the mechanical structure layout.

[0030] When a workpiece is in a fixed posture during cleaning and drying, areas may not come into contact with the cleaning fluid or hot airflow, leading to incomplete cleaning or uneven drying. Therefore, in one embodiment, the oscillating assembly 700 includes a second drive device 710, a second rotating shaft 720, and two clamping arms 730. The second rotating shaft 720 is horizontally positioned at the bottom of the movable part of the vibration assembly 500 and can rotate relative to the vibration assembly 500. The second drive device 710 is located at the bottom of the movable part of the vibration assembly 500 and is drively connected to the second rotating shaft 720. The two clamping arms 730 are respectively located at both ends of the second rotating shaft 720, coaxially aligned with the second rotating shaft 720, and rotate synchronously. The cleaning basket 110 is positioned between the two clamping arms 730. By driving the cleaning basket 110 to oscillate back and forth around a horizontal axis, different parts of the workpiece can alternately contact the cleaning fluid, rinsing water, or hot airflow, effectively eliminating contact blind spots under the traditional fixed posture and improving the uniformity of cleaning and drying.

[0031] Using a motor to directly drive the shaft for forward and reverse rotation requires complex sensors and control systems to achieve precise angle control, resulting in high costs and susceptibility to interference. Therefore, in one embodiment, the second drive device 710 includes a third motor 711, a second cam body 712, a second abutment block 713, a third rack 714, a second guide rail 715, a second elastic element 716, and a fifth gear 717. The third motor 711 is located at the bottom of the movable part of the vibration assembly 500. The second guide rail 715 is vertically positioned at the bottom of the movable part of the vibration assembly 500. The third rack 714 is slidably connected to the second guide rail 715. The second elastic element 716 is located at the top of the third rack 714 and the movable part of the vibration assembly 500. Between the moving parts, the second elastic member 716 has a tendency to push the third rack 714 away from the moving part of the vibration assembly 500. The second abutment block 713 is disposed at the bottom of the third rack 714. The second cam body 712 is coaxially disposed with the drive end of the third motor 711 and rotates synchronously. The outline of the second cam body 712 periodically abuts against the bottom surface of the second abutment block 713. The fifth gear 717 is sleeved on the second rotating shaft 720 and is coaxially disposed with the second rotating shaft 720 and rotates synchronously. The fifth gear 717 meshes with the third rack 714. Through the cooperation of the second cam body 712 and the second elastic element 716, the third rack 714 generates a regular vertical reciprocating motion, which is then converted into the reciprocating rotation of the second rotating shaft 720 through gear meshing, realizing the stable swinging motion of the cleaning basket 110. The swing angle and frequency can be precisely controlled by the cam profile and the motor speed. The rotational motion is converted into reciprocating oscillation through the cam and rack mechanism. The overall structure is compact, the power transmission path is clear, and efficient power conversion can be achieved in a limited space. Specifically, the second elastic element 716 is a compression spring.
