[0028] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0029] See also Figure 1-2 In this embodiment, a shaft workpiece wiping device includes a workbench 1, on which are mounted: a clamping assembly 2 for clamping the workpiece and driving it to rotate; a propulsion assembly 3 symmetrically arranged on both sides of the clamping assembly 2 and centrally propulsing the wiping assembly 4 toward the workpiece, the propulsion assembly 3 including a profiling cylinder 36, the piston rod of the profiling cylinder 36 corresponding to the workpiece, and a soft silicone plate profiling block 37 provided on the outer end face of the piston rod of the profiling cylinder 36; a wiping assembly 4 including a stepping motor 41, a dust-free cloth roll 4 2 and the tensioning wheel 43, the tensioning wheel 43 maintains the tension of the dust-free cloth to keep it flat and tight, and the stepping motor 41 drives the dust-free cloth roll 42 to release the dust-free cloth, and together perform the cleaning and wiping action; the soft silicone plate profiling block 37 is arranged on the inner side of the dust-free cloth, and the profiling cylinder 36 pushes the soft silicone plate profiling block 37 to resist the inner wall surface of the dust-free cloth, and drives the dust-free cloth close to the workpiece, so that the dust-free cloth corresponding to the soft silicone plate profiling block 37 can adaptively fit according to the shape of the workpiece, and the clamping component 2 drives the workpiece to rotate to achieve self-cleaning of the workpiece.

[0030] In some embodiments, as Figure 10As shown, the clamping assembly 2 includes a clamping cylinder 21, a clamping claw 22, a rotating motor 23, a mounting seat 24 and a flange sleeve 25. The clamping cylinder 21 drives the clamping claw 22 to open and close, thereby clamping and releasing the workpiece. The clamping cylinder 21 and the clamping claw 22 are fixed to the mounting seat 24. A driving gear 26 is fixedly connected to the bottom of the mounting seat 24. The driving gear 26 is coaxially arranged with the mounting seat 24. The output shaft of the rotating motor 23 drives the driving gear 26 to realize the rotation of the mounting seat 24 around its central axis. The mounting seat 24 is connected to the workbench 1 through the flange sleeve 25. It should be noted that the setting of the flange sleeve 25 can effectively ensure the coaxiality and structural stability of the connection between the mounting seat 24 and the workbench 1, reduce the radial runout during the rotation of the mounting seat 24, ensure the axial stability of the workpiece during rotation, and provide a precise benchmark for the uniform cleaning of the subsequent wiping assembly 4; the rotating motor 23 is connected to the mounting seat 24 through the flange sleeve 25. The overdrive gear 26 drives the mounting seat 24 to rotate, with high transmission accuracy and rapid response, and can accurately control the rotation angle and speed of the clamping claw 22, and cooperate with the tensioning state of the dust-free cloth in the wiping component 4 to achieve uniform wiping of the workpiece surface, avoiding uneven cleaning caused by speed fluctuations; the structural design of the clamping cylinder 21 driving the clamping claw 22 can provide stable clamping force, ensuring that the seed shaft workpiece does not displace or shake when it rotates at high speed or comes into contact with the dust-free cloth. At the same time, the flexible opening and closing action can adapt to seed shaft workpieces of different diameters, thereby improving the versatility of the device; and the integrated design of the mounting seat 24 and various components, combined with the stable connection of the flange sleeve 25, enables the clamping component 2 to accurately respond to the propulsion action of the profiling cylinder 36 when cooperating with the propulsion components 3 on both sides, ensuring the accuracy of the soft silicone plate profiling block 37 driving the dust-free cloth to fit the workpiece, significantly improving the cleaning quality of the seed shaft workpiece and the operating efficiency of the device.

[0031] In some embodiments, as Figure 1-Figure 4As shown, the propulsion assembly 3 includes a movable plate 33 and a propulsion cylinder 34. The piston rod of the propulsion cylinder 34 is fixedly connected to the movable plate 33. The profiling cylinder 36 is fixed on the movable plate 33. The movement direction of the piston rod of the propulsion cylinder 34 is parallel to the movement direction of the piston rod of the profiling cylinder 36. It should be noted that the propulsion cylinder 34 drives the profiling cylinder 36 to move as a whole by driving the movable plate 33, which can achieve a large-scale coarse adjustment of the wiping assembly 4, and cooperate with the fine push of the piston rod of the profiling cylinder 36 to form a "coarse adjustment + fine adjustment" The two-stage propulsion mode can not only quickly shorten the initial distance between the wiping component 4 and the workpiece, but also accurately control the fitting force between the soft silicone plate profiling block 37 and the workpiece through the profiling cylinder 36, thereby improving operational efficiency and fitting accuracy; the movable plate 33 provides a stable installation reference for the profiling cylinder 36, effectively avoiding the shaking of the profiling cylinder 36 when it moves alone, and ensuring the linearity of its motion trajectory; and the design of the propulsion cylinder 34 and the profiling cylinder 36 piston rod moving in parallel can ensure that the transmission direction of the two-stage propulsion force is consistent, avoiding the local bias or gap when the soft silicone plate profiling block 37 drives the dust-free cloth to contact the workpiece due to the deviation of the force direction, ensuring the uniform fitting of the dust-free cloth to the workpiece surface, further improving the uniformity and reliability of cleaning and wiping, and at the same time, the two-stage propulsion structure can flexibly adapt to seed shaft workpieces of different lengths or diameters, significantly enhancing the adaptability of the device to diversified workpieces.

[0032] In some embodiments, as Figure 1-Figure 5 As shown, a slide 31 and a moving slider 32 are provided between the movable plate 33 and the workbench 1. The slide 31 is fixed on the workbench 1, and the movable plate 33 is mounted on the slide 31 through the moving slider 32. The slides 31 are symmetrically arranged on the upper and lower sides of the movable plate 33. The slide rail movement direction of the slide 31 is parallel to the movement direction of the piston rod of the profiling cylinder 36. It should be noted that the cooperation between the slide 31 and the moving slider 32 provides a precise guide constraint for the movable plate 33, ensuring that the movable plate 33 slides smoothly along the slide rail direction under the drive of the propulsion cylinder 34, effectively eliminating lateral offset or jamming during the movement process; the slides 31 arranged symmetrically above and below can evenly share the load of the movable plate 33 and The weight of the profiling cylinder 36 prevents the movable plate 33 from tilting or shaking due to unilateral force, significantly improving the rigidity and stability of the overall structure; the design that the movement direction of the slide rail is parallel to the movement direction of the piston rod of the profiling cylinder 36 can ensure that the propulsion trajectory of the movable plate 33 is completely consistent with the pushing direction of the profiling cylinder 36, so that the two-stage propulsion action forms a coordinated linear motion, further improving the position accuracy of the soft silicone plate profiling block 37 to drive the dust-free cloth to fit the workpiece; at the same time, the sliding fit reduces the friction resistance of the movement of the movable plate 33, making the propulsion action smoother and more efficient, reducing power loss while extending the service life of the component, and providing reliable guarantee for the stable operation of the wiping device.

[0033] In some embodiments, as Figure 3-Figure 4As shown, a T-block 35 is fixed to the end of the piston rod of the propulsion cylinder 34, and a T-slot 331 is provided on the movable plate 33 to cooperate with the T-block 35, and the T-block 35 is accommodated in the T-slot 331. It should be noted that the cooperation between the T-block and the T-slot can form a two-way constraint in the axial and radial directions, effectively preventing relative rotation or axial separation between the piston rod of the propulsion cylinder 34 and the movable plate 33, ensuring the rigidity and stability of the connection between the two, and avoiding deviation in the propulsion action due to loose connection; this structure can evenly transmit the thrust of the propulsion cylinder 34 to the movable plate 33, reduce local stress concentration, and extend the service life of the connection part; at the same time, the open structure of the T-slot facilitates the rapid installation and disassembly of the T-block, reduces the difficulty of assembly and maintenance, and improves the maintenance efficiency of the device; in addition, the T-type cooperation can also adapt to certain assembly errors, and reduce the assembly jamming problem caused by part processing deviation while ensuring the connection accuracy, further ensuring the smoothness and consistency of the two-stage propulsion action of the propulsion component 3, and providing reliable structural support for the precise control of the dust-free cloth fitting the workpiece.

[0034] In some embodiments, as Figure 1-Figure 2 As shown, the tensioning wheel 43 includes a unwinding wheel 431, an elastic wheel 432, a connecting wheel 433 and a winding wheel 434. The dust-free cloth roll 42 is installed on the unwinding wheel 431, and the dust-free cloth roll 42 of the unwinding wheel 431 passes through the elastic wheel 432, the connecting wheel 433 and the winding wheel 434 in turn. It should be noted that the cooperation between the unwinding wheel 431 and the winding wheel 434 realizes the continuous feeding of the dust-free cloth, so that there is always a fresh dust-free cloth involved in the wiping process, avoiding the contaminated cloth surface from contaminating the workpiece again, and significantly improving the cleaning effect; the connecting wheel 433 accurately guides the path of the dust-free cloth to prevent it from deviating or entangled during movement, thereby ensuring the stability of the wiping action; the overall tensioning wheel 43 structure maintains the optimal working state of the dust-free cloth through the coordinated action of multiple wheels, and realizes the orderly replacement of the cloth surface, which greatly improves the continuous operation capability and cleaning reliability of the wiping component 4.

[0035] In some embodiments, as Figure 6As shown, a winding gear 44 is fixed to the lower end of the winding wheel 434, and the winding gear 44 and the winding wheel 434 are coaxially arranged. The stepper motor 41 drives the winding gear 44 to rotate, and a spring plunger 5 is installed on the movable plate 33. The plunger head of the spring plunger 5 is against the lower end surface of the unwinding wheel 431. It should be noted that the stepper motor 41 drives the winding gear 44 to drive the winding wheel 434 to rotate, which can accurately control the winding speed and winding amount, ensure that the release of the dust-free cloth matches the winding rhythm, and avoid accumulation or excessive stretching of the cloth surface; the plunger head of the spring plunger 5 and the unwinding The lower end surfaces of the wheels 431 are against each other, which can provide stable damping for the unwinding wheel 431 through the spring force, preventing the dust-free cloth from loosening or a sudden drop in tension due to inertia during the unwinding process, and cooperating with the pulling force of the reeling wheel 434 to form a dynamic balance, further maintaining the flatness and tautness of the dust-free cloth; the synergistic effect of the two makes the dust-free cloth more stable in tension and more stable in movement during the feeding process, effectively reducing the cleaning dead corners caused by the shaking of the cloth surface during wiping, and avoiding fluctuations in the friction force between the cloth surface and the workpiece, significantly improving the wiping uniformity and cleaning quality, and extending the effective use length of the dust-free cloth.

[0036] In some embodiments, as Figure 7-Figure 9 As shown, a reset seat 45, a reset slider 46, a reset rod 47 and a reset spring 48 for the dust-free cloth roll 42 to be stretched in between the elastic wheel 432 and the movable plate 33 are provided. The reset seat 45 includes a reset slide 451, and the reset slider 46 is accommodated in the reset slide 451. The reset slide 46 is provided with a reset hole 461 at the end away from the workpiece, and the reset slide 451 is provided with a reset baffle 452 at the end away from the workpiece. The reset rod 47 is sequentially inserted into the through hole of the reset baffle 452 and the reset hole 461, and the reset spring 48 is sleeved on the reset rod 47, and the two ends of the reset spring 48 are respectively against the end surface of the reset baffle 452 and the end surface of the reset slider 46. It should be noted that the reset slide 451 is a reset slide. The positioning slider 46 provides directional constraints to ensure that it only slides in the direction of approaching or moving away from the workpiece, preventing the elastic wheel 432 from deviating and affecting the path of the dust-free cloth; the reset rod 47 runs through the reset baffle 452 and the slider, which not only limits the radial shaking of the reset spring 48, but also provides rigid support for the movement of the slider, thereby enhancing the stability of the structure; the reset spring 48 continuously pushes against the slider through elastic force, so that the elastic wheel 432 can adaptively fine-tune with the tension fluctuation of the dust-free cloth, and compensate for the tension change in real time to keep the cloth surface flat and tight; this structure, in conjunction with the contouring cylinder 36 and the soft silicone plate contouring block 37, can allow the dust-free cloth to fit the contour of the workpiece more closely, reduce the sudden tension change and impact force during wiping, reduce the wear of the dust-free cloth, and improve the cleaning uniformity and device reliability.

[0037] In some embodiments, as Figure 7-Figure 9As shown, a limit baffle 453 is provided at one end of the reset groove 451 near the workpiece. It should be noted that the reset groove 451 of the reset seat 45 provides precise guidance for the reset slider 46, ensuring that it slides smoothly only in the direction of approaching or away from the workpiece, avoiding the elastic wheel 432 from deflecting during the adjustment process; the reset rod 47 passes through the reset baffle 452 and the reset slider 46, which not only limits the radial shaking of the reset spring 48, but also provides rigid support for the movement of the mobile slider 32, ensuring the stability of the overall structure; the reset spring 48 abuts the reset baffle 452 and the reset slider 46 at both ends, and can continuously apply elastic preload to the elastic wheel 432 Force, when the dust-free cloth generates tension fluctuations due to changes in feeding or tensioning state, the reset spring 48 can drive the reset slider 46 and the elastic wheel 432 to adaptively fine-tune the position through expansion and contraction, compensate for the tension change in real time, and always maintain the flat and tight state of the dust-free cloth; this structure enables the elastic wheel 432 to have flexible adjustment capabilities, and cooperates with the soft silicone plate profiling block 37 pushed by the profiling cylinder 36 to better adapt to the subtle contours of the workpiece surface, avoiding uneven wiping force due to sudden changes in the dust-free cloth tension, and effectively buffering the instantaneous impact force during the wiping process, reducing the wear of the dust-free cloth, extending its service life, and further improving the stability and reliability of cleaning and wiping.

[0038] Workflow: S1. Initial preparation stage After the device is powered on, it enters the waiting state. The dust-free cloth roll 42 of the wiping component 4 is pre-installed on the unwinding wheel 431, and is guided by the elastic wheel 432 and the connecting wheel 433 and then wound on the reeling wheel 434. The tensioning wheel 43 maintains the initial tension of the dust-free cloth through the pre-tightening force of the return spring 48; the propulsion cylinder 34 and the contouring cylinder 36 of the propulsion component 3 are both in the retracted state, and the soft silicone plate contouring block 37 maintains a safe distance from the workpiece placement area; the clamping claw 22 of the clamping component 2 is in the open state, waiting for the workpiece to be loaded.

[0039] S2. Workpiece clamping and positioning The operator places the workpiece between the clamping jaws 22 of the clamping assembly 2. The control system triggers the clamping cylinder 21, and the piston rod drives the clamping jaws 22 to close, securing the workpiece coaxially through symmetrical clamping force. At this point, the drive gear 26 below the mounting base 24 meshes with the output gear of the rotating motor 23. The flanged bushing 25 ensures the coaxiality of the mounting base 24 and the worktable 1, providing a stable reference for workpiece rotation.

[0040] S3, propulsion component 3 coarse adjustment propulsion The propulsion cylinders 34 of the propulsion assemblies 3 on both sides are activated synchronously. The piston rods, rigidly connected through T-blocks and T-slots, drive the movable plate 33, which translates along the vertically symmetrical rails of the slide 31 toward the workpiece (the rails are parallel to the piston rods of the contouring cylinders 36). This allows the wiping assembly 4 to rapidly approach over a wide range, shortening the initial distance. The cooperation between the slide 31 and the movable block 32 eliminates lateral offset of the movable plate 33, ensuring the alignment of the two mechanisms.

[0041] S4, contouring and fine-tuning When the movable plate 33 reaches the preset coarse adjustment position, the piston rod of the contouring cylinder 36 extends, pushing the soft silicone contouring block 37 toward the workpiece. Because the contouring block is made of soft silicone and its inner side abuts the dust-free cloth, it adaptively deforms according to the workpiece's outer contour. Simultaneously, the pressure of the contouring cylinder 36 controls the outer edge of the dust-free cloth to evenly conform to the workpiece surface. At this point, the elastic wheel 432, under the action of the return spring 48, slightly adjusts its position to ensure stable tension on the dust-free cloth during contact.

[0042] S5, cleaning and wiping stage Workpiece rotation drive: The rotary motor 23 of the clamping assembly 2 is started, and the mounting seat 24 and the clamping claw 22 are driven to rotate through the driving gear 26, so that the workpiece rotates at a set speed (such as 300-500r / min) at a constant speed to achieve full exposure of the circumferential surface.

[0043] S6. Feeding and tension adjustment of dust-free cloth: The stepping motor 41 drives the winding gear 44 to rotate, and the winding wheel 434 synchronously winds up the dust-free cloth, and the unwinding wheel 431 passively unwinds under the damping action of the spring plunger 5, forming continuous feeding; when the dust-free cloth generates tension fluctuations due to feeding, the reset slider 46 of the elastic wheel 432 slides along the reset slide groove 451, and the reset spring 48 expands and contracts to compensate for the tension change, cooperating with the connecting wheel 433 for guidance, so as to always keep the cloth surface flat and tight.

[0044] S7. Contour fit maintenance: The contour cylinder 36 continuously provides stable thrust, and the soft silicone plate contour block 37 adapts to the subtle contours of the surface in real time as the workpiece rotates, avoiding wiping gaps and ensuring that the dust-free cloth wipes the workpiece surface evenly.

[0045] S8, cleaning completed and reset After the set wiping time is reached, the rotating motor 23 stops and the workpiece stops rotating; the stepping motor 41 stops for a delay to ensure that the winding wheel 434 takes out the used dust-free cloth roll 42 cleanly; the propulsion component 3 first contracts the profiling cylinder 36 to separate the soft silicone plate profiling block 37 from the workpiece, and then the propulsion cylinder 34 drives the moving plate 33 to return to the initial position along the slide rail of the slide seat 31; the clamping cylinder 21 drives the clamping claw 22 to open, the operator removes the cleaned workpiece, and the device returns to the initial state, waiting for the next working cycle.
