[0020] The rack 100 provides a basic support structure; the first driving device 200 drives the connecting frame 300 to move along the first guide rail 150, the lifting assembly 400 drives the cleaning basket 110 to ascend and descend in the vertical direction, so that the cleaning basket 110 can accurately enter or leave different processing devices and realize the transfer between stations; the vibration assembly 500 drives the cleaning basket 110 to reciprocate in the vertical direction, so as to shake off the water droplets on the surface of the workpiece; the swing assembly 700 drives the cleaning basket 110 to reciprocate around the horizontal axis, so as to change the position of the workpiece in the processing device; the transmission assembly 600 converts the lifting movement of the lifting assembly 400 into the vibration driving of the vibration assembly 500, so as to realize the synchronous operation of lifting and vibration. The cleaning basket 110 is driven by the swing assembly 700 to reciprocate around the horizontal axis, so that the workpiece changes the position in each processing device, avoids the cleaning dead angle and the drying dead angle, ensures that each part of the workpiece can fully contact with the cleaning liquid, the rinsing water and the like, and can be uniformly heated during drying; the cleaning basket 110 is driven by the vibration assembly 500 to reciprocate in the vertical direction, so that the water droplets attached to the surface of the workpiece are shaken off when the workpiece leaves and enters each processing device, which creates excellent conditions for subsequent drying, and can realize spotless drying; the transmission assembly 600 utilizes the relative movement between the movable part of the lifting assembly 400 and the fixed second rack 610 during lifting, drives the gear set 620 to rotate, and then drives the movable part of the vibration assembly 500 to reciprocate, converts the lifting movement into the vibration driving of the vibration assembly 500, and realizes the synchronous operation of lifting and vibration, thereby improving the operation efficiency and stability of the equipment.

[0021] During work, the workpiece is placed in the cleaning basket 110, the first driving device 200 drives the connecting frame 300 to move along the first guide rail 150, so that the cleaning basket 110 reaches above the ultrasonic cleaning device 120; then the lifting assembly 400 drives the cleaning basket 110 to descend, so that the cleaning basket 110 enters the ultrasonic cleaning device 120 to be cleaned, the swing assembly 700 can drive the cleaning basket 110 to reciprocate around the horizontal axis during cleaning, so as to improve the cleaning effect; after cleaning is completed, the lifting assembly 400 drives the cleaning basket 110 to ascend and leave the ultrasonic cleaning device 120, the first driving device 200 moves the cleaning basket 110 above the rinsing device 130, then the lifting assembly 400 drives the cleaning basket 110 to descend and enter the rinsing device 130 to be rinsed, and the swing assembly 700 can change the posture of the workpiece in the cleaning basket 110, so as to improve the rinsing effect; after rinsing is completed, the lifting assembly 400 drives the cleaning basket 110 to ascend, the vibration assembly 500 drives the cleaning basket 110 to reciprocate in the vertical direction, so as to shake off the water droplets on the surface of the workpiece, then the first driving device 200 moves the cleaning basket 110 above the drying device 140, the lifting assembly 400 drives the cleaning basket 110 to descend and enter the drying device 140 to be dried, and finally the whole cleaning process is completed.

[0022] In the horizontal movement of the cleaning basket 110, it is easy to shake, shake and other unstable phenomena, which is not conducive to the continuous and stable operation of the entire production line. Therefore, in an embodiment, the first driving device 200 includes a first motor 210, a first rack 220 and a first gear, the first motor 210 is arranged on the connecting frame 300, the first rack 220 is arranged on the rack 100 and arranged in parallel with the first guide rail 150, the first gear is coaxially arranged with the driving end of the first motor 210 and rotates synchronously, and the first gear is engaged with the first rack 220. By driving the first gear to engage with the first rack 220 arranged on the rack 100 through the first motor 210, a more accurate linear motion control can be achieved, so that the cleaning basket 110 can accurately reach the corresponding ultrasonic cleaning, rinsing, drying and other stations, ensuring that each process is carried out in order and smoothly, and avoiding the influence of position deviation on cleaning, rinsing and drying effect; the transmission mode of the gear and the rack is stable in movement, which can reduce the shaking and deviation of the cleaning basket 110 during movement.

[0023] In the case of power failure or shutdown, the cleaning basket 110 may fall due to gravity, which has a safety hazard. Therefore, in an 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 arranged on the connecting frame 300, the lead screw shaft 410 is arranged in a vertical direction on the connecting frame 300 and can rotate relative to the connecting frame 300, the lead screw shaft 410 is coaxially arranged with the driving end of the second motor 430 and rotates synchronously, the lead screw nut 420 is threadedly connected with the lead screw shaft 410, and the lead screw nut 420 is fixedly connected with the fixed part of the vibration assembly 500. The threaded transmission of the lead screw shaft 410 and the lead screw nut 420 has an accurate transmission ratio, which can realize the accurate positioning of the cleaning basket 110 in the vertical direction, ensure that it accurately enters the specified position of the ultrasonic cleaning device 120, the rinsing device 130 or the drying device 140, and ensure the effect of each process; the threaded cooperation of the lead screw nut 420 and the lead screw shaft 410 has a self-locking characteristic, when the second motor 430 stops working, the cleaning basket 110 can be stably stopped at the current height, without the need for additional braking device, saving cost and improving safety.

[0024] Only by the transmission of the screw shaft 410 and the screw nut 420, after lifting the heavy cleaning basket 110 or long time use, the cleaning basket 110 is easy to shake and tilt. Thus, in an embodiment, the lifting assembly 400 further comprises an auxiliary shaft 440 and a sliding block 450, the auxiliary shaft 440 is arranged on the connecting frame 300 and arranged parallel to the screw shaft 410, the sliding block 450 is in sliding connection with the auxiliary shaft 440, and the sliding block 450 is fixedly arranged on the screw nut 420 or the fixed part of the vibration assembly 500. The cooperation of the auxiliary shaft 440 and the sliding block 450 provides additional guiding support for the lifting assembly 400, which can limit its displacement in the non-vertical direction, effectively avoid the shaking and tilting of the cleaning basket 110 caused by the slight eccentricity and uneven force in the screw transmission process, and make the whole lifting process more stable and reliable; the weight of the cleaning basket 110 and related parts will generate a large axial force on the screw assembly, the auxiliary shaft 440 can share part of the axial force generated in the lifting process, reduce the lateral force borne by the screw shaft 410, prolong the service life of the screw assembly, and reduce the maintenance cost of the equipment.

[0025] Water droplets on the surface of the workpiece are difficult to completely remove, and water stains are easily formed after drying, affecting the appearance and performance of the product. Therefore, in an embodiment, the vibration assembly 500 includes a top plate 510, a bottom plate 520, a first elastic member 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 arranged below and parallel to the top plate 510. The first elastic member 530 is arranged between the top plate 510 and the bottom plate 520, and has a tendency to pull the bottom plate 520 towards the top plate 510. The first cam mechanism 540 is arranged at the bottom of the top plate 510 and is in transmission connection with the gear set 620. 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. Through the reciprocating vibration of the bottom plate 520, the water droplets attached to the surface of the workpiece can be forced to fall off, improving the water removal efficiency compared to natural dripping and creating ideal conditions for subsequent drying, effectively avoiding the formation of water stains. The first cam mechanism 540 is in transmission connection with the gear set 620, so that the vibration can be driven by the movement of the lifting assembly 400, without the need for an additional independent power source, simplifying the structure of the equipment and reducing energy consumption and failure rate. With the cooperation of the first elastic member 530 and the first cam mechanism 540, regular and stable reciprocating vibration can be formed, and the amplitude and frequency can be accurately controlled through cam design, adapting to the water removal needs of different workpieces. Specifically, the first elastic member 530 is a tension spring, and the upper and lower ends of the tension spring are connected to the top plate 510 and the bottom plate 520, respectively. The tension spring is always in a stretched state, providing a continuous restoring tension to the bottom plate 520.

[0026] In the power transmission process, instability such as jamming and interruption may occur, which causes irregular vibration of the bottom plate 520 and affects the vibration effect. Thus, in an embodiment, the first cam mechanism 540 includes a first abutting block 541, a first rotating shaft 542, and a first cam body 543. The first rotating shaft 542 is arranged at the bottom of the top plate 510 and can rotate relative to the top plate 510. The first rotating shaft 542 is in transmission connection with the gear set 620. The first cam body 543 is sleeved on the first rotating shaft 542 and is coaxially arranged with the first rotating shaft 542 and synchronously rotates. The first abutting block 541 is arranged on the top surface of the bottom plate 520. The profile of the first cam body 543 periodically abuts against the top surface of the first abutting block 541. The first cam body 543 makes uniform circular motion under the driving of the first rotating shaft 542. The periodic change of the profile causes intermittent abutment and disengagement between the first cam body 543 and the first abutting block 541 during rotation. When abutting, the first abutting block 541 and the bottom plate 520 are pushed to move downward. When disengaging, the bottom plate 520 is reset upward by the elastic restoring force of the first elastic member 530. Through this repeated cycle, the rotational motion transmitted by the first rotating shaft 542 is converted into reciprocating linear motion of the bottom plate 520, thereby realizing the vibration function. The frequency and amplitude of the vibration are accurately controlled by the profile design of the cam body and the rotation speed of the first rotating shaft 542.

[0027] It is difficult to accurately adjust the vibration frequency according to the characteristics of the workpiece by single gear transmission. Inappropriate frequency may cause incomplete water removal or damage to the workpiece. Thus, in an embodiment, the gear set 620 includes a second gear 621, a third gear 622, and a fourth gear 623. The second gear 621 is arranged on the top plate 510 and can rotate relative to the top plate 510. The second gear 621 is in meshing connection with the second rack 610. The third gear 622 is arranged on the top plate 510 and can rotate relative to the top plate 510. The second gear 621 is in meshing connection 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 synchronously rotates. The fourth gear 623 is in meshing connection 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 of the second rack 610 and the lifting assembly 400 can be stably transmitted to the first cam mechanism 540, the transmission efficiency is high, and the power loss is small. By designing gear sets 620 with different numbers of teeth, the transmission ratio can be accurately adjusted, thereby controlling the rotation speed of the first cam mechanism 540 and realizing flexible adjustment of the vibration frequency of the vibration assembly 500 to adapt to the water removal requirements of different workpieces. The meshing of multiple gears can change the power transmission direction, so that the vertical relative motion of the second rack 610 is finally converted into horizontal axial rotation of the first rotating shaft 542, meeting the mechanical structure layout requirements.

[0028] The workpiece is fixed in posture during cleaning and drying, and local areas cannot be contacted by cleaning liquid or hot air flow, resulting in incomplete cleaning or uneven drying. Thus, in an embodiment, the swing assembly 700 includes a second driving device 710, a second rotating shaft 720, and two clamping arms 730. The second rotating shaft 720 is horizontally arranged at the bottom of the movable part of the vibration assembly 500 and can rotate relative to the vibration assembly 500. The second driving device 710 is arranged at the bottom of the movable part of the vibration assembly 500 and is in driving connection with the second rotating shaft 720. The two clamping arms 730 are respectively arranged at the two ends of the second rotating shaft 720 and are coaxially arranged with the second rotating shaft 720 and synchronously rotate. The cleaning basket 110 is arranged between the two clamping arms 730. By driving the cleaning basket 110 to reciprocate around the horizontal axis, each part of the workpiece can alternately contact the cleaning liquid, the rinsing water, or the hot air flow, effectively eliminating the contact blind area under the traditional fixed posture, and improving the uniformity of cleaning and drying.

[0029] The motor directly drives the rotation shaft to rotate forward and backward, which needs complex sensors and control systems to realize accurate angle control, and is high in cost and susceptible to interference. Thus, in an embodiment, the second driving device 710 includes a third motor 711, a second cam body 712, a second abutting block 713, a third rack 714, a second guide rail 715, a second elastic member 716, and a fifth gear 717. The third motor 711 is arranged at the bottom of the movable part of the vibration assembly 500. The second guide rail 715 is arranged at the bottom of the movable part of the vibration assembly 500 in the vertical direction. The third rack 714 is in sliding connection with the second guide rail 715. The second elastic member 716 is arranged between the top of the third rack 714 and the movable part of the vibration assembly 500. The second elastic member 716 has a tendency to push the third rack 714 away from the movable part of the vibration assembly 500. The second abutting block 713 is arranged at the bottom of the third rack 714. The second cam body 712 is coaxially arranged with the driving end of the third motor 711 and rotates synchronously. The profile of the second cam body 712 periodically abuts against the bottom surface of the second abutting block 713. The fifth gear 717 is sleeved on the second rotation shaft 720 and is coaxially arranged with the second rotation shaft 720 and rotates synchronously. The fifth gear 717 is in engagement with the third rack 714. Through the cooperation of the second cam body 712 and the second elastic member 716, the third rack 714 generates regular vertical reciprocating motion, which is converted into reciprocating rotation of the second rotation shaft 720 through gear engagement, so as to realize stable swinging motion of the cleaning basket 110. The swinging angle and frequency can be accurately controlled through the cam profile and the rotation speed of the motor.
