Description

[0001] This application is a divisional application with the application date of January 8, 2025, application number 2025100266323, and the name of which is a stepwise and segmented vehicle screen surface cleaning device. Technical Field

[0002] The present invention belongs to the field of cleaning technology, and in particular relates to a dust-free cloth shifting vehicle-mounted screen surface wiping structure. Background Art

[0003] Currently, in the production of electronic display screens, screen surface cleaning is an essential process. In this cleaning process, impurities on the screen surface are usually wiped with a dust-free cloth.

[0004] However, some car display screens use a curved screen design. In the actual cleaning process, the use of conventional cleaning equipment is prone to the following technical difficulties:

[0005] 1. Conventional cleaning equipment uses a pressure bar to press the dust-free cloth, making it contact the screen surface. The dust-free cloth wipes the screen during the relative movement between the screen and the dust-free cloth. However, when using this method, the dust-free cloth always maintains the same position (i.e., the position where the pressure bar is pressed) to contact the screen for wiping. Therefore, it is difficult to ensure the cleaning effect for the back half of the screen or the screen to be cleaned later, and it is easy to cause secondary contamination.

[0006] 2. Conventional car display screens are all regular curved screens or flat screens. They can be wiped by simply moving the pressure bar horizontally or swinging it regularly relative to the screen surface. However, for car screens that are a combination of curved and flat surfaces, conventional cleaning equipment is difficult to flexibly adapt to changes in the angle of the screen surface, and thus cannot meet cleaning needs. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new dust-free cloth shifting vehicle-mounted screen surface wiping structure.

[0008] To achieve the above object, the present invention adopts the following scheme:

[0009] A dust-free cloth-shifting vehicle screen surface wiping structure is located on the dust-free cloth transmission path, the wiping structure includes a cloth presser, a wiping module extending along the width direction of the vehicle screen and floating with the vehicle screen surface, a wiping power device driving the wiping module to reciprocate along the width direction of the vehicle screen, and a buffer for caching or releasing the dust-free cloth, wherein the wiping section formed by the dust-free cloth adjusts the wiping position of the dust-free cloth based on the cloth presser pressing the dust-free cloth; a resistance end is formed at the bottom of the wiping module, the wiping module contacts the dust-free cloth and presses down to form a V-shaped wiping head, and the wiping head rises and falls synchronously and changes the V-shaped angle as the surface of the vehicle screen changes, and the buffer includes two cache components located on opposite sides of the wiping module, based on the caching or release of the dust-free cloth and the change of the wiping section with the wiping head, the contact position of the wiping module and the dust-free cloth is synchronously changed to adjust the wiping position of the dust-free cloth in the wiping section.

[0010] Preferably, the cloth presser includes a bottom roller and a pressure roller that moves upward and downward above the bottom roller. The dust-free cloth passes around the bottom roller, and the pressure roller presses the dust-free cloth downward against the bottom roller. The pressure roller includes multiple single rollers, and the multiple single rollers are spaced around the centerline of the bottom roller. This provides a good pressing and fixing effect, reducing the possibility of the dust-free cloth loosening.

[0011] According to a specific embodiment and preferred aspect of the present invention, the wiping power device includes a wiping seat, a lifting power component that drives the wiping seat to lift and lower, a transmission mold base fixedly connected to the wiping module, and a wiping power component that is arranged on the wiping seat and drives the transmission mold base to reciprocate and move laterally perpendicular to the width direction of the dust-free cloth, wherein the wiping module is slidably connected to the wiping seat along the width direction of the vehicle-mounted screen.

[0012] Preferably, a strip hole extending along the transmission direction of the vehicle-mounted screen is formed on the transmission mold base, and the wiping power part adopts a motor, wherein the output shaft of the motor is provided with an eccentric wheel matching the strip hole, and the eccentric wheel is installed in the strip hole and drives the transmission mold base to reciprocate in the eccentric motion. Since the dust-free cloth forms a V-shaped wiping head under compression, the movement amplitude of the wiping head must be precisely controlled during the wiping motion (excessive amplitude can easily cause the dust-free cloth to break). The present application adopts the combination of the eccentric wheel and the strip hole, which can accurately achieve a short-distance micro-motion amplitude, and the motor load is small, which can achieve high-frequency and long-term operation, thereby improving the wiping efficiency.

[0013] Preferably, in the orthographic projection across the width of the vehicle screen, the bottom of the abutting end forms a horizontal segment, and in the transmission direction of the vehicle screen, opposite sides of the horizontal segment form arcuate segments, wherein the two arcuate segments are tangent to the horizontal segment. Here, the horizontal segment can precisely match the wiping of a flat screen segment, and the arcuate segment can precisely match the wiping of a curved or inclined screen segment, ensuring effective wiping while reducing the probability of screen damage.

[0014] According to another specific implementation and preferred aspect of the present invention, one of the two cache components caches the dust-free cloth and the other releases the dust-free cloth synchronously, or one of the two cache components caches or releases the dust-free cloth and the other remains stationary. Here, based on the fact that one of the two cache components forms a cache and the other forms a release, it is possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section remain unchanged to suit the wiping of continuous flat sections of the screen, and it is also possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section change to suit the wiping of continuously changing curved sections of the screen; at the same time, based on the fact that one of the two cache components forms a cache and the other remains stationary, it is possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section change to suit the wiping of continuously changing curved sections of the screen; in addition, the two cache components can also be used to periodically synchronize the caching to tighten the dust-free cloth, increase the surface tension of the dust-free cloth to eliminate wrinkles on the surface of the dust-free cloth (wrinkles are easily formed on the surface of the dust-free cloth during long-term reciprocating motion) and improve the flatness of the dust-free cloth, thereby maintaining the cleaning effect while extending the service life of the dust-free cloth, meeting the wiping of a larger number of screens, effectively saving the use of dust-free cloth, and reducing costs.

[0015] Preferably, each cache assembly includes a cache roller that can be raised and lowered and adjusted, and a first guide roller arranged above or below the cache roller. The dust-free cloth passes through the cache roller and the first guide roller in sequence, or passes through the first guide roller and the cache roller in sequence. When caching, the cache roller is adjusted away from the first guide roller, and when releasing, the cache roller is adjusted toward the first guide roller.

[0016] Specifically, the first guide roller can be adjusted toward or away from the wiping module; and / or each buffer assembly further includes a second guide roller, with two second guide rollers disposed at either end of the wiping head, aligned and adjustable in height; and the total length of the wiping head is greater than the distance between the two second guide rollers. Here, the height of the second guide rollers is adjusted to match the height variation of the screen surface, thereby ensuring a V-shaped wiping head. Furthermore, since the total length of the wiping head is greater than the distance between the two second guide rollers, the dust-free cloth between the two second guide rollers is relaxed before the wiping module contacts the dust-free cloth, allowing for adjustment of the wiping position.

[0017] According to another specific embodiment and preferred aspect of the present invention, the wiping structure further includes a sprayer, comprising a spray seat and a spray head mounted on the spray seat for spraying alcohol onto the wiping head. The spray angle of the spray head can be adjusted synchronously with the changes in the surface of the vehicle screen to be wiped. This ensures that the alcohol accurately covers the wiping head at any height or V-angle.

[0018] In addition, a connection module is provided on the spray seat, wherein an arc groove is formed on the connection module, and the spray head is slidably connected in the arc groove; and / or, there are two spray heads and they are arranged on opposite sides of the wiping head in the width direction of the dust-free cloth.

[0019] Due to the application of the above-mentioned technology and equipment solutions, the present invention has the following advantages compared with the prior art:

[0020] The existing cleaning equipment uses a pressure bar to press the dust-free cloth, so that the dust-free cloth contacts the screen surface, and the dust-free cloth wipes the screen during the relative movement between the screen and the dust-free cloth. However, when using this method, the dust-free cloth always maintains the same position (i.e., the position where the pressure bar presses) to contact the screen for wiping, so it is difficult to ensure the cleaning effect for the back half of the screen or the back of the screen to be cleaned; at the same time, conventional car display screens are all regular curved screens or flat screens, and the wiping can be completed by only keeping the pressure bar in regular translation or swinging relative to the screen surface. However, for car screens that are a combination of curved and flat surfaces, conventional cleaning equipment is difficult to flexibly adapt to changes in the angle of the screen surface, and thus cannot meet cleaning needs. The present application makes an overall design of the structure of the dust-free cloth-shifting vehicle-mounted screen surface wiping structure, cleverly solving the shortcomings and defects of the existing technology. After adopting the wiping structure, the vehicle-mounted screen is driven to be transported horizontally and the surface to be wiped is kept facing upward, wherein the wiping section formed by the dust-free cloth wipes the surface of the vehicle-mounted screen; during wiping, the wiping section formed by the dust-free cloth adjusts the wiping position of the dust-free cloth based on the cloth presser pressing the dust-free cloth, and the wiping module extending along the width direction of the vehicle-mounted screen and floating with the surface of the vehicle-mounted screen contacts and presses down to form a V-shaped wiping head, so that the wiping head rises and falls synchronously and changes the V-shaped angle as the surface of the vehicle-mounted screen changes, and the dust-free cloth is cached or released by two cache components located on opposite sides of the wiping module. Finally, based on the caching or release of the dust-free cloth and the synchronous change of the contact position of the wiping module and the dust-free cloth with the change of the wiping head, the wiping position of the dust-free cloth in the wiping section is adjusted. Therefore, compared with the existing technology, the present invention, on the one hand, can precisely match the changes in the vehicle screen surface by synchronously raising and lowering the wiping head and changing the V-shaped angle as the vehicle screen surface changes, and flexibly meet the needs of wiping the continuously changing vehicle screen surface; on the other hand, based on the caching / release under the pressure of the dust-free cloth, the wiping position of the dust-free cloth can be adjusted online in real time, thereby ensuring that the dust-free cloth wipes the vehicle screen surface back and forth at different positions, avoiding secondary contamination and ensuring cleaning quality.

[0037] like Figures 1 to 7 As shown, the segmented and sectional vehicle screen surface cleaning device of this embodiment includes a dust-free cloth reeling and unreeling unit 1, a vehicle screen transmission unit 2, and a wiping unit 3 located on the transmission path of the dust-free cloth B.

[0038] Specifically, the dust-free cloth rewinding and unwinding unit 1 includes an unwinder 10, a rewinder 11, a cloth presser 12, a shaper 13 and a guide roller for assisting the transmission and guiding of the dust-free cloth B; the vehicle-mounted screen transmission unit 2 includes a horizontally extending transmission line 20, a positioning mold base 21 slidably arranged on the transmission line 20 and used to position the vehicle-mounted screen P with the surface to be wiped facing up, wherein the transmission direction of the vehicle-mounted screen P is opposite to the transmission direction of the dust-free cloth B; the wiping unit 3 includes a plurality of wiping groups z that are distributed step by step along the transmission direction of the vehicle-mounted screen P and correspond one-to-one to different wiping sections on the dust-free cloth B, wherein the wiping sections pass through each wiping group z in sequence along the transmission direction of the dust-free cloth, and the surface of the vehicle-mounted screen is wiped in batches by the plurality of wiping groups z.

[0039] In this example, the unwinder 10 and the rewinder 11 are both conventional dust-free cloth unwinding and rewinding mechanisms, which will not be described in detail here; the cloth presser 12 is correspondingly arranged between each two adjacent wiping groups z and is used to press and fix the dust-free cloth B located between the two adjacent wiping groups z.

[0040] In some specific embodiments, the cloth presser 12 includes a bottom roller 120 and a pressing roller 121 that is movable up and down above the bottom roller 120. The dust-free cloth passes around the bottom roller 120, and the pressing roller 121 is driven downward by a cylinder to press the dust-free cloth B against the bottom roller 120. The pressing roller 121 includes multiple single rollers a, and the multiple single rollers a are spaced apart around the centerline of the bottom roller 120. This provides a good pressing and fixing effect, reducing the possibility of the dust-free cloth coming loose.

[0041] For ease of implementation, the dust-free cloth rewinding and unwinding unit 1 also includes a shaper 13 positioned along the dust-free cloth B's transport path, adjacent to the unwinder 10 and rewinder 11. The shaper 13 comprises a base 130 positioned below the dust-free cloth B and a shaping plate 131 that moves upward and downward above the cloth B. The shaping plate 131 presses the dust-free cloth B against the top surface of the base 130, forcing the cloth to be smoothly rewound and unwound. The shaping plate 131 protrudes downward from its center, forming a shaping end portion "b" extending along the width of the cloth. The shaping plate maintains the cloth's flatness during unwinding and rewinding, preventing folds or wrinkles on the cloth, ensuring a clean surface, and facilitating smooth rewinding.

[0042] In this example, the wiping pressure generated by multiple wiping groups z on the surface of the vehicle screen increases step by step along the transmission direction of the vehicle screen. Here, by gradually increasing the wiping pressure in stages, the wiping effect is gradually improved, avoiding damage to the screen caused by excessive pressure in one wiping.

[0043] In some specific embodiments, each wiping group z includes a wiping module 30 that extends along the width of the vehicle screen P and floats along the surface of the vehicle screen P, and a wiping power unit 31 that drives the wiping module 30 to reciprocate along the width of the vehicle screen. The wiping module 30 contacts and presses down on the dust-free cloth B to form a V-shaped wiping head t. The wiping head t rises and falls synchronously with the changes in the surface of the vehicle screen, and the wiping section also changes the contact position between the wiping module 30 and the dust-free cloth B with the changes in the wiping head t to adjust the wiping position of the dust-free cloth B in the wiping section. At the same time, each wiping section adjusts the wiping position of the dust-free cloth B based on the pressure of the dust-free cloth B by the cloth presser 12. Here, the buffering or release of the dust-free cloth under pressure and fixation facilitates the control of the total length of the wiping section, allowing for precise control of the surface tension of the V-shaped wiping head, thereby improving the wiping effect. At the same time, it can avoid interference with the dust-free cloths in other processes in the staged and segmented cleaning line.

[0044] The bottom of the wiping module 30 forms a rubber-made contact end. In its orthographic projection across the width of the vehicle screen P, the bottom of the contact end forms a horizontal segment 300 and two curved segments 301 located on opposite sides of the horizontal segment 300 in the transmission direction of the vehicle screen P. The curved segments 301 on either side are tangent to the horizontal segment 300. The horizontal segment precisely matches the wiping of flat screen sections, while the curved segment precisely matches the wiping of curved or inclined screen sections, ensuring effective wiping while minimizing the risk of screen damage.

[0045] The wiping power unit 31 includes a wiping base 310, a lifting power member 311 that drives the wiping base 310 to move up and down, a transmission mold base 312 fixedly connected to the wiping module 30, and a wiping power member 313 disposed on the wiping base 310 and driving the transmission mold base 312 to reciprocate transversely in a direction perpendicular to the width of the dust-free cloth B. The wiping module 30 is hung and slidably connected to the wiping base 310 along the width of the vehicle-mounted screen. A strip hole k extending along the transmission direction of the vehicle-mounted screen is formed on the transmission mold base 312. The wiping power member 313 uses a motor, wherein the output shaft of the motor is provided with an eccentric wheel c that matches the strip hole. The eccentric wheel c is installed in the strip hole k and drives the transmission mold base 312 to reciprocate in the eccentric motion. Since the dust-free cloth forms a V-shaped wiping head under compression, the movement amplitude of the wiping head must be precisely controlled during the wiping movement (too large an amplitude can easily cause the dust-free cloth to break). This application uses an eccentric wheel and a strip hole to accurately achieve a short-distance and micro-motion amplitude, and the motor load is small, which can achieve high-frequency and long-term operation, thereby improving wiping efficiency.

[0046] To further facilitate implementation, each wiping group z also includes a buffer 32 arranged on the dust-free cloth transmission path and used to cache or release the dust-free cloth. When adjusting the wiping position of the dust-free cloth in the wiping section, the height and V-angle of the wiping head t are adjusted based on the caching or release of the dust-free cloth.

[0047] In each wiping group z, the buffer 32 includes two buffer components 320 located on opposite sides of the wiping module 30 on the dust-free cloth transmission path, wherein one of the two buffer components 320 buffers the dust-free cloth and the other releases the dust-free cloth synchronously, or one of the two buffer components 320 buffers or releases the dust-free cloth and the other remains stationary. Here, based on the fact that one of the two cache components forms a cache and the other forms a release, it is possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section remain unchanged to suit the wiping of continuous flat sections of the screen, and it is also possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section change to suit the wiping of continuously changing curved sections of the screen; at the same time, based on the fact that one of the two cache components forms a cache and the other remains stationary, it is possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section change to suit the wiping of continuously changing curved sections of the screen; in addition, the two cache components can also be used to periodically synchronize the caching to tighten the dust-free cloth, increase the surface tension of the dust-free cloth to eliminate wrinkles on the surface of the dust-free cloth (wrinkles are easily formed on the surface of the dust-free cloth during long-term reciprocating motion) and improve the flatness of the dust-free cloth, thereby maintaining the cleaning effect while extending the service life of the dust-free cloth, meeting the wiping of a larger number of screens, effectively saving the use of dust-free cloth, and reducing costs.

[0048] Specifically, each cache assembly 320 includes a cache roller d0 that can be raised and lowered by a conventional telescopic cylinder d00, a first guide roller d1 and a second guide roller d2 arranged above or below the cache roller d0. The dust-free cloth B passes through the cache roller d0 and the first guide roller d1 in sequence, or passes through the first guide roller d1 and the cache roller d0 in sequence. When caching, the cache roller d0 is adjusted in the direction away from the first guide roller d1, and when releasing, the cache roller d0 is adjusted in the direction close to the first guide roller d1; the first guide roller d1 can be adjusted in the direction close to or away from the wiping module 30; the two second guide rollers d2 are arranged at both ends of the wiping head t, and the two second guide rollers d2 are flush and can be raised and lowered; the total length of the wiping head t is greater than the distance between the two second guide rollers d2. Here, the height of the second guide roller is adjusted to match the height change of the screen surface to ensure that a V-shaped wiping head can be formed. At the same time, based on the fact that the total length of the wiping head is greater than the spacing between the two second guide rollers, that is, before the wiping module contacts the dust-free cloth, the dust-free cloth between the two second guide rollers is in a relaxed state to adjust the wiping position.

[0049] In addition, each wiping group z also includes a sprayer 33, which includes a spray seat 330 and a spray head 331 mounted on the spray seat 330 and used to spray alcohol onto the wiping head t. The spray angle of the spray head 331 can be adjusted synchronously with the changes in the surface to be wiped of the vehicle-mounted screen P. This ensures that the alcohol accurately covers the wiping head at any height or V-angle.

[0050] Specifically, a connection module e is provided on the spray seat 330, wherein an arc groove e0 is formed on the connection module e, and the spray head 331 is slidably connected in the arc groove e0; there are two spray heads 331 and they are arranged on opposite sides of the wiping head t in the width direction of the dust-free cloth B.

[0051] In summary, after adopting this cleaning equipment, the vehicle-mounted screen is driven to be transported horizontally and the surface to be wiped is kept facing upward, and the transmission direction of the dust-free cloth is driven to be opposite to the transmission direction of the vehicle-mounted screen, wherein the multiple wiping sections on the dust-free cloth pass through each wiping group in turn to wipe the surface of the vehicle-mounted screen in batches; in each wiping, the wiping module extending along the width direction of the vehicle-mounted screen and floating with the surface of the vehicle-mounted screen contacts and presses down with the dust-free cloth to form a V-shaped wiping head, which rises and falls synchronously and changes the V-shaped angle as the surface of the vehicle-mounted screen changes to match the wiping requirements at any position on the surface of the vehicle-mounted screen. In addition, the wiping section of the dust-free cloth changes the contact position of the wiping module and the dust-free cloth synchronously with the change of the wiping head to adjust the wiping position of the dust-free cloth in the wiping section. Therefore, compared with the prior art, the present invention is based on the reverse transmission of the dust-free cloth and the vehicle-mounted screen, so that the cleanliness of the dust-free cloth in contact with the vehicle-mounted screen can be gradually improved during the multiple and segmented wiping, which significantly improves the cleaning effect. At the same time, the used dust-free cloth can be used for the cleaning of the next vehicle-mounted screen, effectively reducing the consumption of dust-free cloth and reducing costs. On the other hand, the wiping head rises and falls synchronously with the changes in the surface of the vehicle-mounted screen and changes the V-shaped angle to accurately match the changes in the surface of the vehicle-mounted screen, and flexibly meet the needs of wiping the surface of the vehicle-mounted screen with multiple changes. In addition, the online real-time adjustment of the dust-free cloth is realized. The wiping position is controlled by the dust-free cloth, thereby ensuring that the dust-free cloth wipes the surface of the vehicle screen back and forth at different positions, avoiding secondary contamination and ensuring the cleaning quality; thirdly, based on the caching or release under the pressure and fixation of the dust-free cloth, it is convenient to control the total length of the wiping section, so as to be able to accurately control the surface tension of the V-shaped wiping head formed and improve the wiping effect; at the same time, it can avoid interference with the dust-free cloth in other processes in the segmented and segmented cleaning line; fourthly, when the dust-free cloth is unrolled and reeled, the dust-free cloth is driven to remain flat by the shaping plate, so as to avoid folding or wrinkling of the dust-free cloth and ensure that the dust-free cloth is formed The cleaning area is formed, and the dust-free cloth is easy to roll up smoothly; fifthly, by increasing the wiping pressure step by step, the wiping effect is gradually improved, avoiding damage to the screen caused by excessive pressure in one wiping; sixthly, since the dust-free cloth forms a V-shaped wiping head under compression, the movement amplitude of the wiping head must be accurately controlled during the wiping movement (excessive amplitude can easily cause the dust-free cloth to break). The present application adopts the combination of the eccentric wheel and the strip hole, which can accurately achieve a short-distance and micro-motion amplitude, and the motor load is small, which can achieve high frequency and long-term operation, thereby improving the wiping efficiency; seventhly, On the one hand, the horizontal section can accurately match the wiping of the flat section of the screen, and the arc section can accurately match the wiping of the curved or inclined section of the screen, ensuring the wiping effect while reducing the probability of screen damage; on the eighth hand, based on the two cache components, one forms a cache and the other forms a release, it is possible to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section remain unchanged to adapt to the wiping of the continuous flat section of the screen, and to adjust the wiping position of the dust-free cloth while the height and V-shaped angle of the wiping section change to adapt to the wiping of the continuously changing curved section of the screen;At the same time, with one of the two buffer components forming a buffer and the other remaining stationary, the wiping position of the dust-free cloth can be adjusted as the height and V-angle of the wiping section change, adapting to the wiping of continuously changing curved screen sections. In addition, the two buffer components can also periodically synchronize and tighten the dust-free cloth, increasing its surface tension to eliminate wrinkles on the surface of the dust-free cloth (which are easily wrinkled during long-term reciprocating motion) and improving its flatness. This ensures the cleaning effect while extending the service life of the dust-free cloth, meeting the needs of wiping a larger number of screens, effectively saving dust-free cloth usage, and reducing costs. Ninthly, the spray angle of the spray head can be adjusted synchronously with the changes in the surface of the vehicle screen to be wiped, ensuring that the alcohol accurately covers the wiping head at any height or V-angle.
