Description

Technical Field

[0001] The invention belongs to the field of cleaning technology, and in particular relates to a vehicle-mounted screen cleaning process based on segmented, graded and automatically rolled-up wiping cloths. Background Art

[0002] Currently, after processing, the vehicle display screen needs to be inspected and laminated. However, before lamination, the surface of the display screen needs to be cleaned to wipe off surface stains or dust. The cleaning method used is to wipe the surface of the display screen with a wiping cloth.

[0003] However, once the car display screen has a curved surface, ordinary wiping will not meet the cleaning needs, and there will be the following defects:

[0004] 1) The wiping cloth used cannot float with the changes of the curved surface. Therefore, the wiping force formed cannot be balanced, resulting in a high rate of residual stains or dust, which in turn affects the quality of the subsequent lamination;

[0005] 2) The wiping sections formed by the wiping cloth used are all used to wipe the screen at the same position. Once the screen stains are difficult to remove, since the wiping surface formed by the wiping sections does not change, the screen is continuously cleaned with the wiping cloth containing stains. Therefore, not only is the decontamination ability formed poor, but the stains on the wiping sections may also adhere to the display screen again. Obviously, it cannot meet the cleaning needs;

[0006] 3) The wiping force used only relies on the friction between the display screen and the wiping surface formed by the wiping segment. Once there are stains that are difficult to clean, the wiping force formed is difficult to meet the 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 vehicle screen cleaning process based on segmented, graded and automatically rolled-up wiping cloths.

[0008] To achieve the above-mentioned purpose, the scheme adopted by the present invention is: a vehicle-mounted screen cleaning process based on segmented, graded, and automatically rolled-up wiping cloth, wherein the cleaning equipment adopted comprises a vehicle-mounted screen translation transmission unit, and a wiping unit arranged in a graded manner along the moving direction of the vehicle-mounted screen, wherein the wiping unit comprises a wiping cloth unwinding mechanism, and a plurality of wiping mechanisms spaced and distributed on the moving path of the wiping cloth, wherein each wiping mechanism forms a V-shaped wiping segment based on pressing down against the wiping cloth, wherein the position of the wiping surface corresponding to the V-shaped wiping segment is changed during caching and release, and the V-shaped wiping segment can also wipe synchronously with the reciprocating motion of the pressing wiping part, and the vehicle-mounted screen cleaning process comprises the following steps:

[0009] S1. Car screen path setting

[0010] Place the vehicle-mounted screen with the side to be cleaned facing upward, and transfer the vehicle-mounted screen from back to front based on the horizontal movement of the carrier;

[0011] S2. Path setting of wiping cloth

[0012] The wiping cloth path is laid out based on the rear end being the release end and the front end being the reeling end, and the wiping cloth is transferred from front to back and in sections;

[0013] S3, graded wiping

[0014] During wiping, a V-shaped wiping section is formed based on the downward pressure of the wiping part, and at the same time, multi-stage wiping is performed by the V-shaped wiping sections arranged in sequence along the transmission direction of the vehicle-mounted screen, wherein the wiping force formed by each stage of wiping along the transmission direction of the vehicle-mounted screen increases step by step, and during each stage of wiping, the angle of each V-shaped wiping section changes synchronously based on the change of the surface to be cleaned, and the V-shaped wiping section keeps wiping back and forth along the wide direction of the vehicle-mounted screen, and at the same time, the wiping surface position of the V-shaped wiping section is changed based on the cache and release of the wiping cloth so that the wiping cloth moves in the opposite direction to the transmission direction of the vehicle-mounted screen, and is wiped in the motion until the vehicle-mounted screen has been wiped step by step by multiple V-shaped wiping sections, and the winding end and the releasing end are automatically wound and unwound synchronously to change the position of the wiping cloth to form the V-shaped wiping section, and the length of the V-shaped wiping section formed by wiping at each stage is equal and the effective wiping length formed is L, and the automatic winding and unwinding uses L as the standard to perform release and winding of the same length.

[0015] Preferably, in step S2, the wiping cloth transmission section corresponding to each wiping mechanism is in a horizontal state, and the downward pressing wiping part is pressed downward from the middle of the transmission section to form a V-shaped wiping section.

[0016] According to a specific implementation and preferred aspect of the present invention, in step S3, each level of wiping is completed successively to avoid mutual interference between multiple levels of wiping.

[0017] In some specific embodiments, the cleanliness of the multi-stage wiping along the transmission direction of the vehicle-mounted screen gradually increases; and the cleanliness of each V-shaped wiping section distributed along the transmission direction of the wiping cloth gradually decreases.

[0018] Furthermore, the width of the wiping cloth covers the width of the vehicle screen. To avoid the possibility of missing wiping, the width of the wiping cloth is generally slightly larger than the width of the vehicle screen.

[0019] Based on the automatic unwinding, the same length is released and reeled in with L as the standard. The effective wiping length and the unwinding length are kept equal to ensure that each released cloth can perform multi-level wiping, which improves the wiping quality while controlling the consumption of the wiping cloth. At the same time, the wiping force formed by each level of wiping along the transmission direction of the vehicle-mounted screen increases step by step, so that the cleaning efficiency and quality are the best, because the wiping cloth is wiped from dirty to clean, that is, not only the probability of secondary contamination of the cleaning screen caused by the dirty cloth is reduced, but also different wiping forces are provided by making full use of the different degrees of contamination received by the wiping cloth, and at the same time, the consumption of the wiping cloth is reduced to the best.

[0020] According to another specific implementation and preferred aspect of the present invention, each wiping mechanism includes a wiping head that reciprocates along the width direction of the vehicle-mounted screen, and a lifting assembly that drives the wiping head to adapt to the height difference of the surface to be cleaned, wherein the wiping head includes an external seat, a downward pressing wiping part installed on the external seat and capable of reciprocating, and the lifting assembly is installed on the external seat. The lifting and reciprocating motions are relatively separated to avoid motion interference between the two, and the amplitude of the reciprocating motion involved is small.

[0021] Preferably, the downward-pressing wiping part includes a shift seat connected to an external seat based on a slide rail, and a pressure strip module detachably mounted at the bottom of the shift seat, wherein the length of the pressure strip module is greater than or equal to the width of the wiping cloth, and the wiping mechanism also includes a power device installed on the external seat and used to drive the shift seat to reciprocate.

[0022] Furthermore, the cross section of the exposed part of the layering strip module forms a U-shape with the opening facing upward, and the tip of the V-shaped wiping section is rounded, so that the contact area formed is larger, especially for some curved surfaces, the contact effect formed is better.

[0023] In some specific embodiments, the shift seat is horizontally hung on the slide rail, and a connecting ear is formed on one side of the shift seat. The power device includes a power motor fixedly mounted on the external seat with the output shaft facing downward, and an eccentric wheel installed at the bottom of the output shaft, wherein the connecting ear matches the eccentric wheel and drives the connecting ear to perform linear reciprocating motion during the rotation of the eccentric wheel.

[0024] Specifically, a strip hole extending along the transmission direction of the vehicle-mounted screen is formed on the connecting ear. The strip hole matches the eccentric wheel to accurately achieve short-distance and micro-motion amplitude. The motor load is small, and high-frequency and long-term operation can be achieved, which is convenient for improving wiping efficiency.

[0025] According to another specific implementation and preferred aspect of the present invention, each wiping mechanism further includes a cleaning liquid sprayer, wherein the cleaning liquid sprayer can spray the cleaning liquid onto the surface to be cleaned of the vehicle screen and / or the wiping cloth of the V-shaped wiping section. Based on the premise that the cleaning liquid further improves the cleaning quality and reduces friction, the ability of the wiping cloth to absorb stains is further increased.

[0026] Preferably, the lower end of the cleaning liquid sprayer faces the downward wiping portion, and the cleaning liquid is sprayed toward the inner wall of the wiping cloth of the V-shaped wiping section. This avoids the cleaning liquid from being sprayed directly onto the screen, but rather is absorbed by the wiping cloth for wiping, so that the wiping is more uniform and is done in one go, reducing the residual rate of cleaning liquid on the display screen surface.

[0027] According to another specific implementation and preferred aspect of the present invention, the wiping cloth unwinding mechanism includes an unwinder at the front end, a reel at the rear end, a plurality of buffers corresponding to each wiping mechanism, and a transmission roller group, wherein the wiping cloth forms a wiping cloth path based on unwinding, buffering and reeling. With the layout of the wiping cloth path, the wiping cloth can be continuously replaced, and each wiping section is wiped multiple times to fully use the wiping cloth.

[0028] Preferably, each buffer comprises a buffer roller formed in the wiping cloth path, and a power assembly driving the buffer roller to move up and down to release or reel in the wiping cloth, wherein the power assembly is a cylinder, a hydraulic cylinder or an electric cylinder. The contact position of the wiping section is changed in the synchronous movement of buffering and lifting.

[0029] In some specific embodiments, two buffers are provided on opposite sides of each wiping mechanism, and the two buffers move synchronously and cooperate to release and retract the wiping position of the V-shaped wiping section. In other words, the wiping position can be changed based on the interaction of the two buffers, one releasing and the other retracting, without changing the height of the downward-pressing wiping part, so as to increase the practicality of the device.

[0030] In addition, a cloth pressing roller group is provided between two adjacent wiping mechanisms, and step-by-step wiping is performed based on the squeezing and release matching of the cloth pressing roller group; the wiping cloth is pressed to avoid mutual interference between adjacent levels of wiping.

[0031] At the same time, the transmission roller group is based on the layout of each wiping mechanism. Further, the transmission roller group includes a transmission roller that is adjusted up and down and is located at the bottom, and an adjustment roller that is adjusted along the horizontal direction and is located above the transmission roller, wherein the wiping cloth bypasses the transmission roller and the adjustment roller, and the wiping cloth that bypasses the transmission roller is in a horizontally arranged transmission section, and the downward pressure wiping part is located on the center line of the transmission section and is adjusted to float up and down along the center line.

[0032] As for the implementation method of floating adjustment, it can be: program-controlled lifting based on parameter information obtained in advance; or adaptive adjustment and control of lifting based on the force change of the downward pressing wiping part. No matter which method is used, in order to ensure the stability of lifting, the cooperation of the guide rod and the guide sleeve is added.

[0033] Due to the application of the above-mentioned technology and equipment solutions, the present invention has the following advantages compared with the prior art:

[0034] When cleaning the existing in-vehicle display screen, the wiping cloth used cannot float with the change of the curved surface. Therefore, the wiping force formed cannot be balanced, resulting in a high residual rate of stains or dust, which in turn affects the quality of the subsequent coating. At the same time, the wiping sections formed by the wiping cloth used all wipe the screen surface at the same position. Once the screen stains are difficult to remove, since the wiping surface formed by the wiping section remains unchanged, the wiping cloth containing stains is used to continuously clean the screen. Therefore, not only is the decontamination ability formed poor, but the stains on the wiping section may also adhere to the display screen again. Obviously, it cannot meet the cleaning needs. In addition, the Wiping only relies on the friction between the display screen and the wiping surface formed by the wiping segment. Once there are stains that are difficult to clean, the wiping force formed is difficult to meet the cleaning needs and other shortcomings. The present application makes an overall design of the vehicle screen cleaning process, cleverly solving the shortcomings and defects of the prior art, and adopts a vehicle screen cleaning process based on segmentation, grading, and automatic winding of the wiping cloth. First, the vehicle screen is turned upside down with the surface to be cleaned, and the vehicle screen is transferred from back to front based on the horizontal movement of the carrier; then, the wiping cloth path is laid out based on the rear end as the releasing end and the front end as the winding end, and the wiping cloth is transferred from front to back and segment by segment; finally, during wiping, based on The downward pressing wiping part presses down to form a V-shaped wiping section, and at the same time, the V-shaped wiping sections arranged in sequence along the transmission direction of the vehicle-mounted screen perform multi-stage wiping, wherein in each stage of wiping, the angle of each V-shaped wiping section changes synchronously based on the change of the surface to be cleaned, and the V-shaped wiping section keeps wiping back and forth along the wide direction of the vehicle-mounted screen, and at the same time, the wiping surface position of the V-shaped wiping section is changed based on the buffering and release of the wiping cloth; until the vehicle-mounted screen is wiped step by step by multiple V-shaped wiping sections, the reeling end and the releasing end are automatically reeled and unwound synchronously to change the position of the V-shaped wiping section formed by the wiping cloth. Therefore, compared with the prior art, the present invention is based on the change of each V-shaped wiping section as the surface to be wiped changes. The floating changes are produced to meet the cleaning needs of various vehicle-mounted screens. At the same time, graded wiping is performed based on multiple V-shaped wiping sections arranged in sequence, and the movement mode of the wiping cloth formed is opposite to the transmission of the vehicle-mounted screen, so that each V-shaped wiping section can be wiped multiple times, and the wiping cloth used is cleaner as the vehicle-mounted screen moves forward, that is, the consumption of wiping cloth is small, and each section participates in wiping multiple times to improve the cleaning quality and efficiency; on the other hand, based on the change of the reciprocating motion force during wiping, sufficient wiping force is maintained, and during wiping, the wiping position selected by the V-shaped wiping section can be changed based on the cooperation of releasing and retracting the wiping cloth, which not only improves the decontamination ability of the wiping cloth, but also reduces the probability of stains on the wiping cloth adhering to the display screen again.

[0049] like Figures 1 to 8 As shown, the vehicle screen cleaning process of this embodiment is based on the segmented, graded and automatically rolled-up wiping cloth, and the cleaning equipment used includes a vehicle screen translation transmission unit ① and wiping units ② arranged in grades along the moving direction of the vehicle screen.

[0050] Specifically, the structure adopted by the vehicle-mounted screen translation transmission unit ① includes a transmission belt G, and the vehicle-mounted screen P is fixed on the shift seat Y with the screen facing upward, and the shift seat Y is fixed on the transmission belt G.

[0051] The wiping unit ② includes a wiping cloth unwinding mechanism J and a plurality of wiping mechanisms C spaced apart on the moving path of the wiping cloth. The moving direction of the wiping cloth b is opposite to the transmission direction of the vehicle-mounted screen P. Each wiping mechanism C forms a V-shaped wiping section based on the downward pressure on the wiping cloth, wherein the position of the wiping surface corresponding to the V-shaped wiping section is changed during the buffering and release, and the V-shaped wiping section can also wipe synchronously with the reciprocating motion of the downward pressure wiping part.

[0052] In this example, the wiping cloth unwinding mechanism J includes an unwinder 1 at the front end, a reel 2 at the rear end, a plurality of buffers 3 corresponding to each wiping mechanism C, and a transmission roller group 4, wherein the wiping cloth b forms a wiping cloth path based on unwinding, caching and rewinding. With the layout of the wiping cloth path, the continuous replacement of the wiping cloth is achieved, and each wiping section is wiped multiple times to make full use of the wiping cloth. Each wiping mechanism C includes a wiping head 5 that reciprocates along the width direction of the vehicle-mounted screen P, and a lifting component 6 that drives the wiping head 5 to adapt to the height difference of the surface to be cleaned, wherein the wiping head 5 includes an external seat 50, a downward pressing wiping part 51 installed on the external seat 50 and capable of reciprocating, and the lifting component 6 is installed on the external seat 50. The lifting and reciprocating movements are relatively separated to avoid motion interference between the two, and the amplitude of the reciprocating motion involved is small. Specifically, the lifting assembly 6 uses a telescopic rod 60 as a power drive (cylinder or hydraulic cylinder or electric cylinder), and uses a guide rod 61 and a guide sleeve 62 to form a motion guide.

[0053] Specifically, the unwinder 1 and the reel 2 are wound in a conventional reel manner, and each buffer 3 includes a buffer roller 30 formed in the wiping cloth path, and a power assembly 31 that drives the buffer roller 30 to move up and down to release or reel in the wiping cloth, wherein the power assembly 31 is a cylinder, a hydraulic cylinder, or an electric cylinder. The contact position of the wiping section is changed based on the synchronous movement of caching and lifting. Two buffers 3 are provided on the opposite sides of each wiping mechanism C, and the two buffers 3 move synchronously to cooperate to form a release and reel to adjust the wiping position of the V-shaped wiping section. In other words, the wiping position can also be changed based on the interaction of the two buffers, one releasing and the other reeling, without changing the height of the downward-pressed wiping part, so as to increase the practicality of the equipment. The transmission roller group 4 is arranged based on each wiping mechanism C. Furthermore, the transmission roller group 4 includes a transmission roller 40 that is adjusted up and down and located at the bottom, and an adjustment roller 41 that is adjusted along the horizontal direction and located above the transmission roller 40, wherein the wiping cloth b bypasses the transmission roller 40 and the adjustment roller 41, and the wiping cloth b that bypasses the transmission roller 40 is a horizontally arranged transmission section b1, and the downward pressing wiping part 51 is located on the center line of the transmission section and is adjusted up and down along the center line. In some specific embodiments, a cloth pressing roller group 7 is also provided between two adjacent wiping mechanisms C, and the wiping is performed step by step based on the squeezing and release matching of the cloth pressing roller group 7; the wiping cloth is pressed to avoid mutual interference between adjacent two levels of wiping. In this example, the cloth pressing roller group 7 is a pressing roller 70 that moves relative to each other up and down.

[0054] Furthermore, the downward-pressing wiping portion 51 includes a shift seat 510 connected to the external seat 50 based on a slide rail h, and a pressure strip module 511 detachable from the bottom of the shift seat 510, wherein the length of the pressure strip module 511 is greater than or equal to the width of the wiping cloth b, and the wiping mechanism C also includes a power device 52 installed on the external seat 50 and used to drive the shift seat 510 to reciprocate.

[0055] In some specific embodiments, the cross-section of the exposed part of the pressure strip module 511 forms a U-shape with the opening facing upward, and the tip of the V-shaped wiping section is rounded. In this way, the contact area formed is larger, especially for some curved surfaces, the contact effect formed is better. The shift seat 510 is horizontally hung on the slide rail h, and a connecting ear e is formed on one side of the shift seat 510. The power device 52 includes a power motor 520 fixedly mounted on the external seat 50 and with the output shaft facing downward, and an eccentric wheel 521 installed at the bottom of the output shaft, wherein the connecting ear e matches the eccentric wheel 521, and the connecting ear e is moved to reciprocate linearly during the rotation of the eccentric wheel 521. Specifically, a strip hole extending along the transmission direction of the vehicle-mounted screen is formed on the connecting ear e, and the strip hole matches the eccentric wheel, accurately realizing the short-distance micro-motion amplitude, and the motor load is small, which can achieve high frequency and long-term operation, and is convenient for improving the wiping efficiency.

[0056] In addition, each wiping mechanism C also includes a cleaning liquid injector 8, wherein the cleaning liquid injector 8 can spray the cleaning liquid onto the surface to be cleaned of the vehicle-mounted screen and / or the wiping cloth of the V-shaped wiping section. Based on the premise that the cleaning liquid further improves the cleaning quality and reduces friction, the ability of the wiping cloth to absorb stains is further increased. Preferably, the lower end of the cleaning liquid injector 8 is directed toward the downward-pressing wiping portion 51, and the formed cleaning liquid is sprayed onto the inner wall of the wiping cloth of the V-shaped wiping section. Avoid spraying the cleaning liquid directly onto the screen, but instead absorb it and wipe it with the wiping cloth, so that the wiping is more uniform, and it is all wiped once, reducing the residual rate of cleaning liquid on the surface of the display screen. In this example, the angle and position formed by the cleaning liquid injector 8 can be adjusted and set, and the cleaning liquid sprayed is alcohol. And the cleaning liquid injector 8 is a product purchased from the market, and its nozzle tube is close to the downward-pressing wiping portion 51, and can avoid the wiping cloth b.

[0057] In some specific implementations, the wiping unit ② forms two levels, front and back, and defines coarse wiping and fine wiping, and the specific implementation includes the following steps:

[0058] S1. Car screen path setting

[0059] The vehicle-mounted screen is placed with the surface to be cleaned facing upwards, and the vehicle-mounted screen is transferred from back to front based on the horizontal movement of the carrier, and is subjected to coarse wiping and fine wiping in sequence;

[0060] S2. Path setting of wiping cloth

[0061] The wiping cloth path is laid out based on the rear end being the release end and the front end being the reeling end, and the wiping cloth is transferred from front to back and in sections;

[0062] S3, graded wiping

[0063] First, coarse wiping is performed, and a V-shaped wiping section is formed by pressing down the wiping part. At the same time, as the surface to be cleaned changes, the angles of each V-shaped wiping section change synchronously (that is, up and down adaptive adjustment), and the V-shaped wiping section keeps wiping back and forth along the width direction of the vehicle-mounted screen. In addition, the wiping surface position of the V-shaped wiping section is changed based on the cache and release of the wiping cloth, that is, the coarse wiping of the display screen surface is completed in the change of the wiping surface of the V-shaped wiping section; secondly, fine wiping is performed, and its adoption process is the same as the coarse wiping process, but the difference is that the wiping force formed by the present application is greater than the former, that is, the fine wiping of the display screen surface is completed while the wiping force is increased while the wiping surface of the V-shaped wiping section changes; finally, the lengths of the V-shaped wiping sections formed by the coarse wiping and the fine wiping are equal and the effective wiping lengths formed are both L, and after wiping is completed, the automatic roll-up is performed to release and retract the same length based on L as the standard.

[0064] In this example, only one wipe is used for coarse-level wiping and fine-level wiping. However, multiple wipes are used for each level of wiping depending on the difficulty of screen decontamination.

[0065] In some specific embodiments, in the above step S2, the wiping cloth transmission section corresponding to each wiping mechanism is in a horizontal state, and the downward wiping part is pressed downward from the middle of the transmission section to form a V-shaped wiping section. In step S3, the wiping of each level is completed successively to avoid mutual interference between the multi-level wiping. At the same time, the wiping force formed by each level of wiping along the transmission direction of the vehicle-mounted screen increases step by step, so that the cleaning efficiency and quality formed are the best, because the wiping cloth is from dirty to clean, that is, not only the probability of secondary contamination of the cleaning screen caused by the dirty cloth is reduced, but also the different degrees of contamination received by the wiping cloth are fully utilized to provide different wiping forces, and at the same time, the consumption of the wiping cloth is optimally reduced. The cleanliness of each V-shaped wiping section distributed along the transmission direction of the wiping cloth gradually decreases. The width of the wiping cloth covers the width of the vehicle-mounted screen. To avoid the probability of missing wiping, the width of the wiping cloth is generally slightly larger than the width of the vehicle-mounted screen. As for the implementation method of floating adjustment, it can be: program control lifting based on parameter information obtained in advance; or adaptive adjustment control lifting based on the force change of the downward wiping part. Regardless of the method, in order to ensure the smoothness of lifting and lowering, the coordination of guide rods and guide sleeves is added.

[0066] In summary, after adopting the vehicle screen cleaning process based on segmentation, grading and automatic rolling of the wiping cloth, first, the vehicle screen is turned upward with the surface to be cleaned, and the vehicle screen is transferred from back to front based on the horizontal movement of the carrier; then, the wiping cloth path is laid out based on the rear end as the release end and the front end as the reeling end, and the wiping cloth is transferred from front to back and segment by segment; finally, during wiping, a V-shaped wiping segment is formed based on the downward pressure of the wiping part, and at the same time, multi-stage wiping is performed by the V-shaped wiping segments arranged in sequence along the transmission direction of the vehicle screen, wherein at each stage of wiping, the angle of each V-shaped wiping segment changes synchronously based on the change of the surface to be cleaned, and the V-shaped wiping segment keeps wiping back and forth along the wide direction of the vehicle screen, and at the same time, the wiping surface position of the V-shaped wiping segment is changed based on the caching and release of the wiping cloth; until the vehicle screen has been wiped step by step by multiple V-shaped wiping segments, the reeling end and the release end are moved to ... The release end is automatically rolled up and released synchronously to change the position of the V-shaped wiping section formed by the wiping cloth. Therefore, compared with the prior art, on the one hand, the present invention is based on the floating change of each V-shaped wiping section as the surface to be wiped changes, so as to meet the cleaning needs of various vehicle-mounted screens, and at the same time, based on the multiple V-shaped wiping sections arranged in sequence to perform graded wiping, and the movement mode of the formed wiping cloth is opposite to the transmission of the vehicle-mounted screen, so that each V-shaped wiping section can be wiped multiple times, and as the vehicle-mounted screen moves forward, the used wiping cloth is cleaner, that is, the consumption of wiping cloth is small, and each section participates in wiping multiple times to improve the cleaning quality and efficiency; on the other hand, based on the change of the reciprocating motion force during wiping, sufficient wiping force is maintained, and during wiping, the wiping position selected by the V-shaped wiping section can be changed based on the coordination of releasing and rolling up the wiping cloth.
