Description

Technical Field

[0001] This utility model relates to the field of screen cleaning equipment technology, and in particular to a wiping device. Background Technology

[0002] In the manufacturing process of 3C products, it is necessary to clean the surfaces of components, such as the glass cover protecting the camera, the screen, and the protective glass for the radar scanner on mobile phones. Specifically, alcohol can be sprayed onto a lint-free cloth manually or with a spray nozzle, and then the alcohol-soaked lint-free cloth can be used to clean the surfaces of the glass cover, screen, and protective glass.

[0003] In related technologies, when spraying alcohol onto cleanroom wipes using a nozzle, a single nozzle is typically used to spray alcohol onto multiple wipes simultaneously. While this method improves efficiency, the wipes closer to the nozzle receive a larger amount of alcohol, while those farther away receive a smaller amount. This results in varying amounts of alcohol on the wipes at different locations, leading to inconsistent cleaning effects on surfaces such as glass covers, screens, and protective glass.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0030] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0033] Cleanroom wipes, also known as cleanroom cleaning cloths, are made of 100% polyester double-woven fibers. They have a soft surface, do not shed fibers when rubbed, and have good water absorption and cleaning efficiency. They can be used to wipe sensitive surfaces.

[0034] In the manufacturing process of 3C products, lint-free cloths are typically used to clean the surfaces of components, such as the glass cover protecting the camera, the screen, and the protective glass for radar scanners on mobile phones. Specifically, alcohol is sprayed onto a lint-free cloth manually or using a spray nozzle, and then the alcohol-soaked cloth is used to clean the surfaces of the glass cover, screen, and protective glass.

[0035] In related technologies, when spraying alcohol onto cleanroom wipes using a nozzle, a single nozzle is typically used to spray alcohol onto multiple wipes simultaneously. While this method improves efficiency, the alcohol is easily affected by airflow during spraying, resulting in uneven distribution. Wipes closer to the nozzle receive a larger amount of alcohol, while those farther away receive a smaller amount. Wipes sprayed with more alcohol tend to leave more alcohol residue on the surfaces of glass covers, screens, and protective glass after wiping, causing secondary contamination. Wipes sprayed with less alcohol cannot thoroughly clean the surfaces of glass covers, screens, and protective glass, leading to inconsistent cleaning effects from wipes at different locations.

[0036] Based on this, this application discloses a wiping device to solve the above problems.

[0037] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0038] This application provides a wiping device, such as... Figures 1-9 As shown, the wiping device 10 includes a frame 1, a wiping assembly 2, a spraying assembly 3, and a conveying assembly 4. The wiping assembly 2 is mounted on the frame 1 and is used to bring the cleaning belt 20 against the surface 30 to be wiped, so that the cleaning belt 20 can wipe the surface 30. The spraying assembly 3 is mounted on the frame 1 and is adjacent to the wiping assembly 2. The spraying assembly 3 includes a flow divider 31 and a nozzle 32. The flow divider 31 has multiple flow divider holes 311, one end of each flow divider hole 311 being connected to a liquid storage tank. The nozzle 32 has multiple spray hole groups 321, which are arranged along a first direction (e.g., ...). Figure 1The nozzles are arranged at intervals (as shown in the x-direction). Each branch nozzle 311 is connected to a spray nozzle group 321 at the other end. Each spray nozzle group 321 includes at least one spray nozzle 3211 for spraying wiping liquid. The conveying component 4 is disposed on the frame 1 and is used to convey the cleaning belt 20 so that the cleaning belt 20 can pass through multiple spray nozzles 3211 and the wiping component 2 in sequence. This means that the cleaning belt 20 can pass through the spraying area and wiping area of ​​multiple spray nozzle groups 321 in sequence. The wiping area is the area directly opposite to the side of the wiping component 2 that is used to abut the receiving wiping surface 30. The first direction is parallel to the width direction of the cleaning belt 20.

[0039] It should be noted that the wiping area mentioned above refers to the area where the wiping component 2 is used to bring the cleaning tape 20 against the surface 30 to be wiped, or the area between the wiping component 2 and the surface 30 to be wiped.

[0040] In this embodiment, the wiping assembly 2 is used to bring the cleaning belt 20 against the surface 30 to be wiped, so that the cleaning belt 20 can wipe the surface 30. The spray holes 3211 in the nozzle 32 are used to spray wiping liquid. The transmission assembly is used to transport the cleaning belt 20 so that the cleaning belt 20 can pass through multiple spray holes 3211 and the wiping assembly 2 in sequence. When the cleaning belt 20 passes through the spray area of ​​multiple spray hole groups 321, the spray holes 3211 can spray wiping liquid onto the cleaning belt 20, so that the cleaning belt 20 can be wetted with wiping liquid. Then the cleaning belt 20 is transmitted to the wiping area, and the wiping assembly 2 can bring the cleaning belt 20 wetted with wiping liquid against the surface 30 to be wiped, so that the cleaning belt 20 wetted with wiping liquid can wipe and clean the surface 30 to be wiped, thereby enabling the cleaning belt 20 to have a better cleaning effect on the surface 30 to be wiped.

[0041] The spray assembly 3 includes a diverter 31 and a nozzle 32. The diverter 31 has multiple diverting holes 311, one end of which is connected to a storage tank. The nozzle 32 has multiple spray hole groups 321, which are spaced apart along a first direction. The other end of each diverter 311 is connected to a corresponding spray hole group 321. Each spray hole group 321 includes at least one spray hole 3211, allowing one diverter 311 to be connected to one spray hole group 321. This ensures that the wiping liquid flowing from the storage tank to the diverter 311 can flow to the corresponding spray hole group 321. This design ensures that the amount of wiping liquid flowing into each group of spray holes 321 is approximately the same, and that the amount of wiping liquid sprayed onto the cleaning belt 20 by each group of spray holes 321 is approximately the same. This results in the cleaning belt 20 at different locations along the first direction being soaked in approximately the same amount of wiping liquid, thus ensuring that the wiping and cleaning effect on the surface 30 to be wiped is good and highly consistent at different locations. On the other hand, when a diversion hole 311 or spray hole 3211 becomes blocked due to a malfunction, it does not affect the spraying of wiping liquid from other spray holes 3211, thereby improving the reliability of the wiping device 10.

[0042] In addition, the multiple spray nozzle groups 321 are arranged at intervals along the first direction, and the first direction is parallel to the width direction of the cleaning belt 20. This allows the amount of wiping liquid sprayed onto each part of the cleaning belt 20 along the first direction to be approximately the same. This ensures that the amount of wiping liquid sprayed onto each part of the cleaning belt 20 along its width direction is approximately the same. This results in better consistency in the wiping and cleaning effect of the cleaning belt 20 on the surface 30 to be wiped at different positions along the first direction. At the same time, it also allows each part of the cleaning belt 20 along its width direction to be used to wipe the surface 30 to be wiped, improving the utilization rate of the cleaning belt 20 and helping to control costs.

[0043] The cleaning belt 20 can be any of the following: a dust-free cloth, a microfiber cloth, an eyeglass cloth, etc., and there is no limitation on it.

[0044] Alternatively, the wiping solution can be any of the following: alcohol, coconut oil derivatives, nano-plating model cleaner, etc. The following detailed explanation uses cleaning tape 20 (a lint-free cloth) and alcohol as the wiping solution as an example.

[0045] The number of the aforementioned diversion holes 311 can be two, three, or more, depending on the actual situation; this embodiment does not limit this. The number of injection hole groups 321 corresponds to the number of diversion holes 311, and can be two, three, or more, depending on the actual situation; this embodiment also does not limit this.

[0046] The multiple diversion holes 311 are independent of each other, which makes the wiping liquid flowing in each diversion hole 311 less affected by other diversion holes 311. This ensures that the wiping liquid flowing in each diversion hole 311 is roughly the same, so that the amount of wiping liquid flowing to each spray hole group 321 is basically consistent. This makes the amount of wiping liquid sprayed onto the cleaning belt 20 by each spray hole group 321 more uniform, which is more conducive to improving the wiping and cleaning effect of the cleaning belt 20 on the wiping surface 30.

[0047] Optionally, such as Figures 4-6 As shown, the diverter 31 is provided with a plurality of air blowing holes 312, which are connected to a plurality of diverter holes 311 in a one-to-one correspondence. The air inlet end of the plurality of air blowing holes 312 is used to connect to a positive pressure system, so that the wiping liquid in the diverter hole 311 is sprayed to the spray hole group 321 by the positive pressure provided by the positive pressure system.

[0048] Therefore, the wiping liquid flowing from the storage tank to the diversion hole 311 can flow more stably and quickly to the spray hole group 321 under the action of positive pressure, and can be sprayed from the spray hole 3211 onto the cleaning belt 20, which is conducive to improving the wetting efficiency of the wiping liquid on the cleaning belt 20. Moreover, under the action of positive pressure, the wiping liquid sprayed from the spray hole 3211 can be more fully atomized, and the sprayed wiping liquid droplets can be finer and more uniform, which significantly improves the coverage density and uniformity of the wiping liquid on the cleaning belt 20, and is more conducive to improving the wiping effect. In addition, the spray volume can be adjusted by adjusting the positive pressure provided by the positive pressure system to adapt to different cleaning needs.

[0049] The number of air blowing holes 312 corresponds to the number of diversion holes 311, and can be two, three or more. There is no limitation here, and the specific number can be set according to the actual situation.

[0050] In addition, such as Figure 5 and Figure 6 As shown, the air outlet of the air blowing hole 312 is positioned relative to the air inlet end, closer to the diversion hole 311, and towards the injection hole 3211.

[0051] This allows the wiping liquid in the diversion hole 311 to flow to the spray hole 3211 more quickly, which is more conducive to improving the wetting efficiency.

[0052] The angle between the extending direction of the air blowing hole 312 and the extending direction of the diversion hole 311 can be 30°, 45°, 60°, etc., and this embodiment does not limit this.

[0053] In some embodiments, such as Figure 5As shown, multiple diversion holes 311 are arranged at intervals along a first direction. This allows the arrangement direction of the multiple diversion holes 311 to be parallel to the arrangement direction of the multiple spray hole groups 321. This facilitates communication between the diversion holes 311 and the spray hole groups 321, and also saves space occupied by the diversion component 31 along the conveying direction of the cleaning belt 20 in the spraying area.

[0054] In other embodiments, such as Figures 7-9 As shown, the nozzle 32 is also provided with multiple spray chambers 3212, which are connected to multiple diversion holes 311 in a one-to-one correspondence, and the end of each spray chamber 3212 away from the diversion hole 311 is connected to a spray hole group 321.

[0055] Therefore, the spray chamber 3212 can provide a certain pressure buffer space, making the pressure of the wiping liquid more stable and uniform before entering the spray hole group 321, reducing pressure fluctuations and improving the uniformity of the sprayed wiping liquid on the cleaning belt 20; and, by connecting one spray chamber 3212 with one spray hole group 321, the flow rate of each spray hole 3211 in the same spray hole group 321 can be more uniform, further improving the uniformity of the distribution of wiping liquid on the cleaning belt 20.

[0056] The cross-section of the spray chamber 3212 is larger than that of the spray hole 3211, so that the flow rate of the wiping liquid can be increased when it flows from the spray chamber 3212 to the spray hole 3211, so that the sprayed wiping liquid can be more fully atomized, further improving the coverage density and uniformity of the wiping liquid on the cleaning belt 20.

[0057] Optionally, the injection hole assembly 321 includes a plurality of injection holes 3211.

[0058] This helps to improve the coverage density and uniformity of the wiping liquid on the cleaning belt 20, resulting in a better wiping effect.

[0059] The number of injection holes 3211 can be two, three or more, and this embodiment does not limit this.

[0060] In addition, the end of the spray cavity 3212 away from the diversion hole 311 can be a tapered surface, so that it extends vertically in the spray cavity 3212. This can effectively reduce the chance of wiping liquid remaining in the spray cavity 3212, reduce the waste of wiping liquid, and help control costs.

[0061] The wiping assembly 2 is configured to simultaneously abut against multiple surfaces 30 to be wiped, the multiple surfaces 30 to be wiped are arranged at intervals along a first direction, and multiple spray hole groups 321 are set one-to-one with the multiple surfaces 30 to be wiped, that is, the multiple spray hole groups 321 are set one-to-one with the multiple surfaces 30 to be wiped, and the spray range of each spray hole group 321 along the first direction matches the size of the corresponding surface 30 to be wiped along the first direction.

[0062] Therefore, multiple surfaces 30 to be wiped can be wiped and cleaned simultaneously, effectively improving efficiency. At the same time, it also ensures that the cleaning band 20 for wiping each surface 30 is sprayed with wiping liquid, resulting in a better wiping effect for each surface 30, and effectively reducing waste of wiping liquid, which is beneficial for cost control.

[0063] Of course, in some other embodiments, the wiping component 2 can also wipe and clean one surface 30 to be wiped at a time, and this embodiment does not limit this.

[0064] Optionally, such as Figure 4 As shown, a first infusion line 33 is connected between the diversion hole 311 and the corresponding injection hole group 321, and a check valve 34 is provided on the first infusion line 33.

[0065] This effectively prevents backflow of wiping fluid and improves the pressure stability and consistency of each spray hole group 321.

[0066] In addition, the diversion hole 311 is connected to the storage tank through the second infusion line, and a pump is installed on the second infusion line to drive the wiping liquid to flow to the spray hole 3211.

[0067] Therefore, the wiping liquid in the storage tank can be quickly and timely delivered to the diversion hole 311 by the pump, and then delivered to the spray hole 3211 to be sprayed onto the cleaning belt 20, which improves the efficiency of the wiping liquid being sprayed onto the cleaning belt 20 and helps to improve the wiping efficiency of the wiping device 10 on the surface 30 to be wiped.

[0068] The pump can be any of the following: peristaltic pump, explosion-proof centrifugal pump, pneumatic diaphragm pump, etc., and this embodiment does not limit it.

[0069] In other embodiments, such as Figure 2 , Figures 10-12 As shown, the wiping assembly 2 includes a first connector 21, a screen wiping head 22, and a first driving member 23. The first connector 21 is positioned along a second direction (e.g., ...). Figure 2 The direction (as shown in the middle y) is slidably disposed on the frame 1, the second direction is perpendicular to the first direction, and is also the conveying direction of the conveying assembly 4 conveying the cleaning belt 20 at the spray hole 3211 (as shown in the middle y). Figure 2The direction shown in z1 intersects with the first connector 21. The screen cleaning head 22 is connected to the first connector 21. Along the second direction, the screen cleaning head 22 is at least partially protruding from the outer surface of the first connector 21. Along the second direction, the end of the screen cleaning head 22 away from the first connector 21 is used to bring the cleaning belt 20 against the surface to be wiped 30. The driving end of the first driving member 23 is connected to the first connector 21 and is used to drive the first connector 21 to slide along the second direction.

[0070] Therefore, the first connecting member 21 can be driven to slide along the second direction by the first driving member 23, so as to drive the screen cleaning head 22 to move along the second direction. When it is necessary to wipe the surface 30 to be wiped, the cleaning strip 20 soaked in wiping liquid can be pressed against the surface 30 to be wiped by the screen cleaning head 22, which effectively improves the wiping quality. When it is not necessary to wipe the surface 30 to be wiped, the screen cleaning head 22 can be moved away from the surface 30 to be wiped along the second direction, which is convenient and quick to operate.

[0071] For example, such as Figure 10 As shown, when the first direction is a first horizontal direction, and the conveying direction of the conveying component 4 conveying the cleaning belt 20 at the spray hole 3211 is a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction, the second direction can be a vertical direction. Of course, this is only an exemplary description of the first direction, the second direction, and the conveying direction, and is not a limitation on the first direction, the second direction, and the conveying direction.

[0072] The first driving component 23 can be any of the following: motor, cylinder, electric cylinder, etc., without limitation.

[0073] Optionally, a guide rail and a slider may also be provided between the first connector 21 and the frame 1. That is, the guide rail is provided on the frame 1 and extends along the second direction, and the slider is provided on the first connector 21 and is slidably connected to the guide rail. This makes it less likely for the first connector 21 to deviate when the first drive member 23 drives the first connector 21 to slide along the second direction.

[0074] In some embodiments, along the first rotation direction (e.g.) Figure 10 (as shown in z in the middle), the screen cleaning head 22 is rotatably set relative to the first connector 21, and the plane where the first rotation direction is located intersects with the conveying direction of the conveying assembly 4 conveying the cleaning belt 20 at the spray hole 3211.

[0075] Therefore, when the end face of the cleaning belt 20 is uneven on the surface to be wiped 30 or the cleaning head 22, the cleaning head 22 can rotate in the first rotation direction, so that the cleaning belt 20 can make sufficient contact with the surface to be wiped 30, reducing the probability of wiping dead corners, and making the pressure between the cleaning belt 20 and the surface to be wiped 30 at each position more uniform, thereby effectively improving the wiping quality.

[0076] The screen cleaning head 22 is rotatably configured relative to the first connector 21 along the first rotation direction, and can be implemented in various ways. For example, the screen cleaning head can be directly rotatably connected to the first connector 21. For instance, the screen cleaning head 22 is rotatably connected to the first connector 21 through a rotating shaft, which is simple in structure and easy to implement. Alternatively, the first connector 21 can be connected to a second connector 25, and the screen cleaning head 22 can be rotatably connected to the second connector 25. Of course, the screen cleaning head 22 can be rotatably configured relative to the first connector 21 along the first rotation direction in other ways, which are not limited here.

[0077] Optionally, when the first connector 21 is connected to the second connector 25, and the screen cleaning head 22 is rotatably connected to the second connector 25, so that the screen cleaning head 22 rotates relative to the first connector 21 in a first rotation direction, specifically, as shown... Figures 10-12 As shown, the wiping assembly 2 also includes a second connector 25, which is connected to the first connector 21. The second connector 25 has a connecting end 251 away from the first connector 21 along a second direction, and the wiping head 22 is rotatably disposed on the connecting end 251 along a first rotation direction.

[0078] Therefore, the rotation of the screen cleaning head 22 along the first rotation direction is less likely to interfere with the first connecting member 21.

[0079] In addition, the second connector 25 is floatingly connected to the first connector 21 along the second direction.

[0080] Therefore, the second connector 25 can be floatingly connected to the first connector 21 in the second direction, so that when the screen cleaning head 22 presses the cleaning belt 20 against the surface to be wiped 30 for wiping, it can better adapt to the changes of the surface to be wiped 30 and reduce wear and damage caused by hard contact.

[0081] Specifically, when the screen cleaning head 22 encounters a protrusion or depression on the surface 30 to be cleaned, the floating connection allows the screen cleaning head 22 to automatically adjust its position along the second direction, avoiding excessive pressure or collision, thereby protecting the screen cleaning head 22 and the surface 30 to be cleaned from damage. Simultaneously, the rotatable design of the connection end 251 between the screen cleaning head 22 and the second connector 25 allows the screen cleaning head 22 to make gentler contact with the surface 30 during cleaning, further reducing the risk of surface damage.

[0082] In addition, such as Figure 10 As shown, the screen cleaning head 22 extends along the first direction, and the middle part of the screen cleaning head 22 is rotatably connected to the connecting end 251 through the rotating shaft 24b. The parts of the screen cleaning head 22 located on both sides of the rotating shaft 24b along the first direction are respectively connected to the connecting end 251 through the first elastic member 24a.

[0083] Therefore, the portion of the screen cleaning head 22 located on both sides of the rotating shaft 24b along the first direction can be elastically constrained by the first elastic member 24a, so that the rotation of the screen cleaning head 22 along the first rotation direction can be relatively stable. At the same time, the adaptive extension and retraction of the first elastic member 24a can make the screen cleaning head 22 press the cleaning belt 20 against the surface to be wiped 30 smoothly, so that the pressure between the cleaning belt 20 and the surface to be wiped 30 at each position along the width direction of the cleaning belt 20 can be more uniform.

[0084] The screen cleaning head 22 extends along the first direction and can be adapted to the width of the cleaning belt 20. This ensures that the pressure of the cleaning belt 20 is uniform at each position along its width direction between the surfaces to be wiped 30, while also effectively preventing the occurrence of wiping dead corners along the width direction of the cleaning belt 20.

[0085] In addition, the first elastic element 24a can be any of the following: spring, elastic rubber, foam, etc., and is not limited here.

[0086] As mentioned above, the first elastic members 24a located on both sides of the rotating shaft 24b can be symmetrically arranged about the central axis of the rotating shaft 24b, so that the two first elastic members 24a have a better elastic constraint effect on the screen cleaning head 22.

[0087] The aforementioned second connector 25 and first connector 21 can be floated together in a second direction in various ways. In one possible implementation, the first connector 21 and the second connector 25 can be connected by a hydraulic buffer, which can precisely adjust the floating distance of the second connector 25.

[0088] In another implementation where the second connector 25 and the first connector 21 are floatingly connected in a second direction, a second elastic member 26 is connected between the second connector 25 and the first connector 21. The second elastic member 26 is used to provide the second connector 25 with an elastic force in the second direction.

[0089] Therefore, the floating connection between the second connector 25 and the first connector is simple and easy to implement, and the second elastic member 26 has both buffering and self-adaptive functions, which can cooperate with the rotation setting of the screen cleaning head 22 to better protect the screen cleaning head 22 and the surface 30 to be cleaned.

[0090] The second elastic element 26 may include at least one of a spring, elastic rubber, elastic column, etc., and this embodiment does not limit it.

[0091] For example, when the second elastic member 26 includes a spring, the spring can extend along the second direction, one end of the spring is connected to the first connecting member 21, and the other end is connected to the second connecting member 25. The connection is simple and easy to implement.

[0092] Optionally, a pressure detection element 27 is also provided between the second connector 25 and the first connector 21. The pressure detection element 27 is used to detect the pressure on the second connector 25 when the cleaning head 22 abuts the cleaning belt 20 against the surface to be wiped 30.

[0093] Therefore, the pressure on the second connector 25 when wiping the surface 30 can be detected more accurately by the pressure detection component 27, and the position of the second connector 25 along the second direction can be adjusted in time by the first driving component 23, thereby adjusting the position of the screen cleaning head 22 along the second direction. This allows for more precise adjustment of the pressure between the cleaning belt 20 and the surface 30 to be wiped, resulting in better wiping and cleaning effect of the cleaning belt 20 on the surface 30.

[0094] The pressure sensing element 27 can be any of the strain gauge pressure sensor, piezoelectric pressure sensor, diaphragm pressure sensor, etc., and this embodiment does not limit it.

[0095] In addition, such as Figure 10 As shown, the wiping assembly 2 also includes a second driving member 28 and a third connecting member 29b. The third connecting member 29b is slidably connected to the first connecting member 21 along the first direction and fixed relative to the first connecting member 21 along the second direction. The second connecting member 25 is slidably disposed on the third connecting member 29b along the second direction. The second driving member 28 is connected to the third connecting member 29b and is used to drive the third connecting member 29b to reciprocate along the first direction.

[0096] Therefore, when wiping the surface 30, the third connector 29b can be driven to reciprocate along the first direction by the second drive member 28, so as to drive the second connector 25 to reciprocate along the first direction, and then drive the screen cleaning head 22 to reciprocate along the first direction, so that the cleaning belt 20 can wipe and clean the surface 30 to be wiped along the width direction of the cleaning belt 20, and the wiping effect is better.

[0097] The implementation of the second driving component 28 is roughly the same as that of the first driving component 23. For details, please refer to the above description, which will not be repeated here.

[0098] In addition, the second driving member 28 driving the third connecting member 29b to reciprocate along the first direction can be implemented in various ways. In one possible implementation, the second driving member 28 may include a cylinder, the piston rod of which may extend along the first direction and be connected to the third connecting member 29b, so as to drive the third connecting member 29b to reciprocate along the first direction by the extension and retraction of the piston rod of the cylinder.

[0099] When another second driving member 28 drives the third connecting member 29b to reciprocate along the first direction, such as Figures 10-14As shown, the second driving member 28 may include a motor, and the wiping assembly 2 may also include an eccentric shaft 29. The eccentric shaft 29 extends along the conveying direction and includes a main body section 291 and an eccentric section 292 connected to each other. The main body section 291 and the eccentric section 292 are radially offset from each other along the eccentric shaft 29. The third connecting member 29b is provided with an elongated slot 293 extending along the second direction. The elongated slot 293 has two opposite sidewalls along the first direction. The driving end of the second driving member 28 is connected to the main body section 291. The eccentric section 292 passes through the elongated slot 293 and abuts against the two sidewalls of the slots respectively. A guide member 29a is also provided between the third connecting member 29b and the first connecting member 21. The guide member 29a extends along the first direction and is used to guide the third connecting member 29b to move along the first direction when the second driving member 28 drives the main body section 291 to rotate and drives the eccentric section 292 to rotate to the sidewall of the slot.

[0100] Therefore, the rotational motion of the motor can be converted into reciprocating linear motion along the first direction through the coordinated cooperation between the eccentric shaft 29 and the elongated slot 293 provided on the third connector 29b, resulting in high transmission efficiency and easy stroke control. In addition, the eccentric shaft 29 extends along the conveying direction of the conveying assembly 4 at the spray hole 3211 to convey the cleaning belt 20, which can effectively reduce the space occupied by the wiping assembly 2 along the first direction and facilitate the use of space by the wiping assembly 2.

[0101] Specifically, when the second driving member 28 drives the eccentric shaft 29 to rotate, the main body section 291 of the eccentric shaft 29 can rotate around the central axis of the main body section 291, and the eccentric section 292 can rotate around the central axis of the main body section 291. When the eccentric section 292 rotates to abut against one of the sidewalls of the elongated slot 293, under the guidance of the guide member 29a, the continued rotation of the eccentric section 292 can drive the third connecting member 29b to move along the first direction toward one side of the sidewall of the slot. When the eccentric section 292 rotates to abut against the other sidewall of the elongated slot 293, the continued rotation of the eccentric section 292 can drive the third connecting member 29b to move along the first direction toward the other sidewall of the slot, so that the third connecting member 29b can drive the screen cleaning head 22 to reciprocate along the first direction. The length of the elongated slot 293 along the second direction is greater than twice the eccentricity of the eccentric shaft 29.

[0102] The guide member 29a can be implemented in several ways. In one possible implementation, the guide member 29a may include a guide rail and a slider. The guide rail extends along a first direction and is disposed on the first connecting member 21. The slider may be disposed on the third connecting member 29b and is slidably connected to the guide rail to guide the guide member 29a to move along the first direction. This structure is simple and easy to implement. In another possible implementation, the guide member 29a may include a groove and a slider. The groove extends along the first direction and is disposed on the first connecting member 21. The slider is disposed on the third connecting member 29b and is slidably embedded in the groove. This can effectively reduce the space occupied by the guide member 29a and save space.

[0103] In addition, the wiping assembly 2 also includes a third connector 29b, which is slidably connected to the first connector 21 along the first direction and fixed relative to the first connector 21 along the second direction. When the third connector 29b and the second connector 25 are slidably connected along the second direction, the second elastic member 26 can also be connected between the second connector 25 and the third connector 29b to realize the floating of the second connector 25 relative to the first connector 21. The pressure detection member 27 can also be disposed between the second connector 25 and the third connector 29b to realize the pressure detection of the second connector 25.

[0104] like Figure 10 As shown, the screen cleaning head 22 may include a detachably connected mounting part 221 and a flexible part 222. Along the second direction, the flexible part 222 is located at the end of the mounting part 221 that is away from the first connector 21.

[0105] Therefore, if the flexible part 222 is damaged, it can be easily removed from the mounting part 221 for maintenance or replacement. In addition, the cleaning tape 20 can be pressed against the surface 30 to be wiped by the flexible part 222 of the screen wiping head 22, so that the elastic deformation of the flexible part 222 can better adapt to the changes of the surface 30 to be wiped, and prevent wear and damage to the screen wiping head 22 and the surface 30 to be wiped due to hard contact.

[0106] The flexible part 222 can be made of any of the following materials: foamed silicone, sponge, rubber, etc., without any limitation.

[0107] Furthermore, the detachable connection between the mounting part 221 and the flexible part 222 can be implemented in various ways. For example, the mounting part 221 and the flexible part 222 can be snapped together, or the mounting part 221 and the flexible part 222 can be connected by screws, or the mounting part 221 and the flexible part 222 can be bonded together by adhesive. No limitation is made here.

[0108] When the screen cleaning head 22 is rotated relative to the first connector 21 in the first rotation direction, the mounting part 221 can be rotatably connected to the first connector 21 in the first rotation direction, or the mounting part 221 can be rotatably connected to the connecting end 251 of the second connector 25 in the first rotation direction, which is not limited here.

[0109] The aforementioned conveying assembly 4 may further include an unwinding shaft 41, a take-up shaft 42, multiple transmission shafts 43, and a conveying drive. The conveying drive can be connected to the take-up shaft 42 and is used to drive the take-up shaft 42 to rotate. The unwinding shaft 41 is used to unwind the rolled cleaning belt 20. The cleaning belt 20 can pass around the multiple transmission shafts 43 sequentially from the unwinding shaft 41 to the take-up shaft 42 for winding.

[0110] In addition, the conveying assembly 4 may also include a clamping member 44, which is used to tighten the cleaning belt 20 before it passes through the spraying area of ​​the multiple spray nozzle groups 321, so that the cleaning belt 20 can be sprayed with wiping liquid in a taut position, which is beneficial to the better consistency of the wiping liquid soaked in the cleaning belt 20 at each position, and thus the cleaning belt 20 can be used to wipe and clean the wiping surface 30 in a taut position, which is beneficial to further improve the wiping effect.

[0111] As described above, when wiping and cleaning the surface 30 to be wiped, the cleaning belt 20 can first be placed on the unwinding shaft 41, and the starting end of the cleaning belt 20 can be sequentially wrapped around multiple transmission shafts 43 and wound onto the take-up shaft 42; then the product to be wiped is placed in the wiping area of ​​the wiping head 22, such as on a carrier located in the wiping area, with the surface 30 to be wiped facing the wiping head 22; then the wiping liquid is sprayed onto the cleaning belt 20 by the spraying assembly 3, and the cleaning belt 20 sprayed with wiping liquid is transferred between the wiping head 22 and the surface 30 to be wiped; then, the first drive The actuator 23 drives the first connector 21 to move along the second direction toward the surface to be wiped 30 until the cleaning belt 20 sprayed with wiping liquid is pressed against the surface to be wiped 30. At the same time, the second drive 28 drives the third connector 29b to reciprocate along the first direction, so as to drive the second connector 25 to reciprocate along the first direction. Then, by rotating the screen cleaning head 22 set on the second connector 25, it presses against the cleaning belt 20, so as to drive the cleaning belt 20 to reciprocate along the first direction. At the same time, the cleaning belt 20 continues to be conveyed to the take-up shaft 42, so as to achieve wiping and cleaning of the surface to be wiped 30, and has a good cleaning effect.
