[0001] The present application belongs to the technical field of projector lens cleaning, and more specifically, relates to a cleaning and wiping mechanism. Background Art

[0002] Projectors are common multimedia devices, widely used in homes, offices, schools, and other places. The core component of a projector is the projector lens, whose image quality directly impacts the projection effect. However, during the production process, projectors are frequently exposed to the human body and the production environment, which can easily leave fingerprints and / or accumulate dust on their surfaces, severely impacting the projection effect.

[0003] In the related art, projector lenses are mainly cleaned manually before leaving the factory. Manual cleaning requires high cleaning knowledge and experience of the cleaning staff, and manual cleaning quality is poor and the efficiency is low. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a cleaning and wiping mechanism to solve the technical problems of poor manual cleaning quality and low efficiency existing in the related art.

[0005] To achieve the above objectives, the present application adopts a technical solution: providing a cleaning and wiping mechanism for use with a projector, the cleaning and wiping mechanism comprising: a first driving member, a second driving member, and a wiping rubber head. The second driving member is connected to the first driving member, the first driving member being configured to drive the second driving member to move in a first direction, and the wiping rubber head is connected to the second driving member, the second driving member being configured to drive the wiping rubber head to rotate so that the wiping rubber head wipes the projector lens, with the wiping rubber head rotating in a direction perpendicular to the first direction.

[0006] Through the above technical solution, the first driving member drives the second driving member to move in the first direction, which can drive the wiping rubber head connected to the second driving member to approach or move away from the lens. The second driving member can drive the wiping rubber head to rotate when the wiping rubber head approaches and abuts the lens, so that the wiping rubber head wipes the lens. In this way, the cleaning and wiping mechanism provided by this application can replace manual cleaning of the lens, which is conducive to improving cleaning quality and cleaning efficiency.

The second direction is perpendicular to the first direction.

[0008] In this way, the first driving member can drive the clamping assembly and the wiping rubber head to move together, and the clamping assembly can clamp or release the projector through the first clamping member and the second clamping member. When the wiping rubber head is wiping the lens, the clamping assembly can be used to clamp the projector to keep the projector stable, to a certain extent preventing the projector from shaking, and facilitating a better lens cleaning effect.

[0010] In this way, the first clamping member and the second clamping member can slide in the second direction under the drive of the third driving member, thereby clamping or releasing the lens without the need for manual adjustment, which is beneficial for improving cleaning efficiency. In addition, the wiping rubber head is located between the first clamping member and the second clamping member, which can reduce the distance between the wiping rubber head and the first and second clamping members, thereby reducing the rotational torque of the projector, which is beneficial for maintaining the stability of the projector and thus providing a better lens cleaning effect. Furthermore, the distance between the wiping rubber head and the first clamping member is equal to the distance between the wiping rubber head and the second clamping member, which can balance the force on the projector, prevent the projector from shaking to a certain extent, and further improve the lens cleaning effect.

In this manner, the second driving member, the wiping rubber head, and the clamping assembly can be respectively connected to the first driving member via the adapter and located on the same side of the first driving member, resulting in a compact structure and reducing space usage.

[0012] In some embodiments of the present application, the cleaning and wiping mechanism provided herein further includes a connecting sleeve, through which the wiping rubber head is connected to the output shaft of the second driving member; and / or a pressure sensor is disposed within the wiping rubber head.

The mounting plate is connected to a support frame, and the detergent bottle is connected to the mounting plate for spraying detergent toward the lens of the projector. The pressing plate is used to press the nozzle of the detergent bottle, and the fourth driving member is connected to the support frame and is connected to the pressing plate for driving the pressing plate to move so that the pressing plate presses the nozzle of the detergent bottle. Of course, after the pressing plate is separated from the nozzle of the detergent bottle, the nozzle of the detergent bottle can be reset. In this way, the fourth driving member can drive the pressing plate to press the nozzle of the detergent bottle and spray detergent onto the lens.

[0015] In some embodiments of the present application, the detergent spray assembly further includes at least one mounting fixture, the mounting fixture including a first clamping block and a second clamping block, the first clamping block being connected to the mounting plate, the second clamping block being connected to the side of the first clamping block facing away from the mounting plate, the first clamping block having a first clamping portion on the side facing away from the mounting plate, and the second clamping block having a second clamping portion on the side facing the mounting plate, the detergent bottle being clamped between the first clamping portion and the second clamping portion.

DETAILED DESCRIPTION

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0036] The surface cleanliness of a projector lens has a direct impact on the projector's projection quality. Fingerprints or dust accumulation on the lens surface will seriously affect the projection quality and lead to a poor user experience. However, during the production process, projectors are frequently exposed to the human body and the production environment, which can easily leave fingerprints and dust on their surfaces. Therefore, it is very important to keep the projector lens clean before leaving the factory.

[0037] In the related art, the projector lens is mainly cleaned by manual cleaning, which involves directly wiping the lens surface with a cleaning cloth or detergent. However, in the mass production process, manual cleaning does not produce a good cleaning effect, and the strength of manual cleaning, as well as the use of cleaning cloth and detergent, have a great impact on lens cleaning. The manual cleaning force is weak, and it is difficult to completely remove fingerprints or dust from the lens surface, especially for some stubborn stains. The manual cleaning force is strong, which may cause damage to the lens. Improper use of hard cleaning cloth or detergent may also scratch the lens surface, affecting its optical performance. The manual cleaning method is complicated to operate, requires professional cleaning knowledge and experience, and the cleaning effect depends on the operator's skill level. Therefore, manual cleaning requires high cleaning knowledge and experience of the cleaning staff, and the quality of manual cleaning is poor and the efficiency is low.

[0038] In order to solve the above problems, the present application provides a cleaning and wiping mechanism.

[0039] Please also refer to Figure 1 、 Figure 2 and Figure 3 , the cleaning and wiping mechanism provided in the embodiment of the present application is now described. The cleaning and wiping mechanism provided in the embodiment of the present application is applied to the projector 01 and is installed on the lens cleaning device 02. The lens cleaning device 02 includes a frame 1, a conveying assembly 2, a positioning block 3 and a cleaning and wiping mechanism 4. The frame 1 includes a workbench 11, an electrical box 12, and a cleaning room 13. The electrical box 12 is located below the workbench 11. The electrical box 12 is used to place electrical components (not shown in the figure). The electrical components are used to supply power, gas or control to each component. This is a technology well known to those skilled in the art and will not be repeated here. The cleaning room 13 is located above the workbench 11 and forms a clean space. Among them, the conveying assembly 2 is installed on the workbench 11 and passes through the clean space. The cleaning and wiping mechanism 4 is located in the cleaning room 13.

[0040] The conveying assembly 2 can move the projector 01 along Figure 2 and Figure 3 The A direction is transported to the cleaning wiping mechanism 4. That is, Figure 2 and Figure 3 The A direction in FIG. 1 is the process direction of the lens cleaning device 02 .

[0041] That is to say, the conveying assembly 2 can extend in a straight line, and the process direction of the lens cleaning device 02 can also be a straight line. Of course, the process direction of the lens cleaning device 02 can also be specifically designed according to the production site and equipment space.

[0042] Please also refer to Figure 3 and Figure 4The cleaning and wiping mechanism 4 is disposed in a cleaning room 13 above the workbench 11 , and can spray cleaning agent onto the lens 011 of the projector 01 and wipe the lens 011 in the cleaning room 13 .

[0043] In this way, the cleaning and wiping mechanism 4 provided in the present application can replace manual work, which is beneficial to improving cleaning efficiency and cleaning quality.

[0044] Therefore, the cleaning and wiping mechanism 4 provided in the present application can solve the technical problem of poor quality and low efficiency of manual cleaning of the lens 011 of the projector 01.

[0045] In some embodiments of the present application, the positioning block 3 is arranged at the starting end of the conveying component 2. The positioning block 3 can position the projector 01 so that the projector 01 can accurately reach the cleaning and wiping mechanism 4. The cleaning and wiping mechanism 4 can accurately spray cleaning agent onto the lens 011 and wipe the lens 011, which is conducive to further improving the cleaning quality.

[0046] Please also refer to Figure 3 、 Figure 4 and Figure 5 In some embodiments of the present application, the cleaning and wiping mechanism 4 includes a support frame 41, which includes a bottom plate 411, a vertical plate 412 and a leg 413. The leg 413 is mounted on the workbench 11, the bottom plate 411 is fixedly connected to the leg 413, the vertical plate 412 is fixed on the bottom plate 411, and along the first direction (such as Figure 4 The Z direction in FIG extends.

[0047] The cleaning and wiping mechanism 4 also includes a detergent spray assembly 42, a first drive member 43, a second drive member 44, and a wiping rubber head 47. The detergent spray assembly 42 is connected to the support frame 41 via a base plate 411 and is used to spray detergent toward the lens 011 of the projector 01. The first drive member 43 is connected to the support frame 41 via a vertical plate 412. The second drive member 44 is connected to the output end of the first drive member 43. The first drive member 43 is used to drive the second drive member 44 to move in a first direction, thereby driving the wiping rubber head 47 connected to the second drive member 44 toward or away from the lens 011. The wiping rubber head 47 is connected to the output shaft of the second drive member 44. The second drive member 44 is used to drive the wiping rubber head 47 to rotate. When the wiping rubber head 47 approaches and abuts the lens 011, the wiping rubber head 47 rotates, thereby wiping the lens 011 of the projector 01. The rotation direction of the wiping rubber head 47 is perpendicular to the first direction.

[0048] It is understandable that the material of the wiping rubber head 47 is a soft and water-absorbent material, so that fingerprints on the surface of the lens 011 can be effectively removed.

[0049] Exemplarily, the wiping rubber head 47 can be foam, sponge, etc.

[0050] In this way, the cleaning and wiping mechanism 4 provided in the present application can replace manual cleaning and wiping of the lens 011, which is beneficial to improving the cleaning quality and cleaning efficiency.

[0051] It is understandable that the second driving member 44 can be directly connected to the output end of the first driving member 43 , or can be connected to the output end of the first driving member 43 through the adapter 45 .

[0052] The first drive member 43 may be a linear drive motor, a linear drive motor, a servo linear drive module, etc. Exemplarily, the first drive member 43 may be a servo linear drive module. The second drive member 44 may be a rotary drive motor, a rotary drive motor, a stepper drive motor, etc. Exemplarily, the second drive member 44 is a stepper drive motor that drives the wiping rubber head 47 to rotate.

[0053] In some embodiments of the present application, the cleaning agent spray assembly 42 is located on the side of the support frame 41 opposite the first drive member 43. That is, the cleaning agent spray assembly 42 is located on one side of the vertical plate 412 in the X direction, and the first drive member 43 is located on the other side of the vertical plate 412 in the X direction. Furthermore, the cleaning agent spray assembly 42 is closer to the starting end of the conveyor assembly 2 than the wiping rubber head 57. In this way, the cleaning and wiping mechanism 4 provided herein can use the cleaning agent spray assembly 42 to spray cleaning agent toward the lens 011 of the projector 01 before wiping the lens 011.

[0054] Please also refer to Figure 4 、 Figure 6 and Figure 7 In some embodiments of the present application, the detergent spraying assembly 42 includes a mounting plate 421, a detergent bottle 422, a pressing plate 424, and a fourth driving member 423. The mounting plate 421 is connected to the support frame 41 via the base plate 411. The detergent bottle 422 is connected to the mounting plate 421 and is used to spray detergent toward the lens 011 of the projector 01. The pressing plate 424 is used to press the nozzle of the detergent bottle 422. The fourth driving member 423 is connected to the support frame 41 and is connected to the pressing plate 424. It is used to drive the pressing plate 424 to move so that the pressing plate 424 presses the nozzle of the detergent bottle 522. Of course, after the pressing plate 424 is separated from the nozzle of the detergent bottle 422, the nozzle of the detergent bottle 422 can be reset. In this way, the fourth driving member 423 can drive the pressing plate 424 to press the nozzle of the detergent bottle 422, spraying detergent toward the lens 011.

[0055] It is understood that the spray pressure of the cleaning agent bottle 422 can be 0.3MPa-0.7MPa, and the spraying time for the lens 011 of a projector 01 is 0.1s-0.3s. This allows the cleaning agent to fully contact fingerprints or dust on the surface of the lens 011, thereby improving the cleaning effect.

[0056] For example, the spraying pressure of the cleaning agent bottle 422 may be 0.5 MPa, and the spraying time for the lens 011 of the projector 01 may be 0.2 s.

[0057] It is understandable that the fourth driving member 423 can be a linear driving motor, a linear driving motor, a linear driving cylinder, etc. Exemplarily, the fourth driving member 423 is a linear driving cylinder.

[0058] Please also refer to Figure 6 and Figure 7 In some embodiments of the present application, the spray cleaner assembly 42 also includes at least one mounting fixture 425, the mounting fixture 425 includes a first clamp 4251 and a second clamp 4252, the first clamp 4251 is connected to the mounting plate 421, and the second clamp 4252 is connected to the side of the first clamp 4251 facing away from the mounting plate 421.

[0059] The first clamping block 4251 has a first clamping portion 42511 on the side facing away from the mounting plate 421, and the second clamping block 4252 has a second clamping portion 42521 on the side facing the mounting plate 421. The detergent bottle 422 is clamped between the first clamping portion 42511 and the second clamping portion 42521. In this way, the detergent bottle 422 can be mounted on the mounting plate 421 using the mounting fixture 425.

[0060] In some embodiments of the present application, an installation space for installing the detergent bottle 422 is defined between the first clamping portion 42511 and the second clamping portion 42521 .

[0061] It is understood that the detergent bottle 422 can be cylindrical or square. The first clamping portion 42511 and the second clamping portion 42521 can be recessed to position the detergent bottle 422. In this way, the detergent bottle 422 can be stably installed between the first clamping portion 42511 and the second clamping portion 42521.

[0062] Illustratively, the first clamping portion 42511 and the second clamping portion 42521 are both arc-shaped recessed portions.

[0063] For example, the first clamping block 4251 may contact the second clamping block 4252. For example, the first clamping block 4251 and the second clamping block 4252 may be spaced a certain distance apart.

[0064] See also Figure 6 In some embodiments of the present application, the mounting plate 421 is provided with a long hole 4211, and the mounting plate 421 is connected to the bottom plate 411 of the support frame 41 through a connecting piece passing through the long hole 4211. The length direction of the long hole 4211 is consistent with the length direction of the detergent bottle 422 (such as Figure 6 4211). When the cleaning agent spray assembly 42 is installed on the support frame 41, the position of the mounting plate 421 can be adjusted along the length of the long hole 4211, and then the connecting piece is locked to fix the mounting plate 421 and the base plate 411 relative to each other. The cleaning agent bottle 422 is mounted on the mounting plate 421, and the position of the nozzle of the cleaning agent bottle 422 can be adjusted along with the mounting plate 421 to align with the lens 011 of the projector 01. In this way, the position of the cleaning agent bottle 422 in the length direction of the cleaning agent bottle 422 can be adjusted through the long hole 4211 and the connecting piece, so that the nozzle of the cleaning agent bottle 422 can spray the cleaning agent onto the surface of the lens 011.

[0065] Please also refer to Figure 5 and Figure 8 In some embodiments of the present application, the cleaning and wiping mechanism 4 also includes an adapter 45, which includes a connecting portion 451, a mounting portion 452 and a supporting portion 453. The connecting portion 451 is perpendicular to the mounting portion 452, and the supporting portion 453 is connected between the connecting portion 451 and the mounting portion 452 to support the connecting portion 451 and the mounting portion 452, thereby improving the strength of the adapter 45.

[0066] The connecting portion 451 is connected to the output end of the first driving member 43 , and the second driving member 44 is connected to the mounting portion 452 , thereby being connected to the first driving member 43 through the adapter 45 .

[0067] In some embodiments of the present application, the cleaning and wiping mechanism 4 further includes a clamping assembly 48, which is used to clamp the projector 01. The clamping assembly 48 includes a clamping assembly 48 in the second direction (eg Figure 5 The first clamping member 481 and the second clamping member 482 are spaced apart in the Y direction (in the Y direction), and the first clamping member 481 and the second clamping member 482 are respectively connected to the output end of the first driving member 43 and are respectively capable of sliding along the second direction. The second direction is perpendicular to the first direction.

[0068] In this way, the first driving member 43 can drive the clamping assembly 48 and the wiping rubber head 47 to move together, and the clamping assembly 48 can clamp or release the projector 01 through the first clamping member 481 and the second clamping member 482. When the wiping rubber head 47 wipes the lens 011, the clamping assembly 48 can be used to clamp the projector 01, so that the projector 01 remains stable and prevents the projector 01 from shaking to a certain extent, which is conducive to providing a good cleaning effect for the lens 011.

[0069] It is understandable that the distance between the first clamping member 481 and the second clamping member 482 can be adjusted manually or automatically by a driving member.

[0070] In some embodiments of the present application, the clamping assembly 48 further includes a third driver 483, which is connected to the mounting portion 452 of the adapter 45 and is thereby connected to the first driver 43 via the adapter 45. The first clamping member 481 and the second clamping member 482 are respectively connected to the first driver 43 via the third driver 483. The third driver 483 can drive the first clamping member 481 and the second clamping member 482 to slide in the second direction. In this way, the first clamping member 481 and the second clamping member 482 can slide in the second direction under the drive of the third driver 483, thereby clamping or releasing the lens 011, eliminating the need for manual adjustment and improving cleaning efficiency.

[0071] It can be understood that the third driving member 483 can be a rotary driving motor, which drives the first clamping member 481 and the second clamping member 482 to slide along the second direction through a ball screw structure (not shown in the figure), and the sliding directions of the first clamping member 481 and the second clamping member 482 are opposite, so that the lens 011 can be clamped or released.

[0072] In addition, the third driving member 483 can be a finger cylinder, which directly drives the first clamping member 481 and the second clamping member 482 to slide along the second direction, and the sliding directions of the first clamping member 481 and the second clamping member 482 are opposite, so that the lens 011 can be clamped or released.

[0073] In some embodiments of the present application, the wiping rubber head 47 is located between the first clamping member 481 and the second clamping member 482. This can reduce the distance between the wiping rubber head 47 and the first clamping member 481 and the second clamping member 482, thereby reducing the rotational torque of the projector 01, which is beneficial for maintaining the stability of the projector 01 and thus facilitating a cleaning effect on the lens 011.

[0074] In some embodiments of the present application, the distance between the wiping rubber head 47 and the first clamping member 481 is equal to the distance between the wiping rubber head 47 and the second clamping member 482. In this way, the distance between the wiping rubber head 47 and the first clamping member 481 is equal to the distance between the wiping rubber head 47 and the second clamping member 482, which can balance the force on the projector 01, prevent the projector 01 from shaking to a certain extent, and further improve the cleaning effect of the lens 011.

[0075] In some embodiments of the present application, rubber pads 484 are provided on the inner sides of the first clamping member 481 and the second clamping member 482 to prevent the first clamping member 481 and the second clamping member 482 from scratching the side of the projector 01 when clamping the projector 01.

[0076] Exemplarily, the rubber pad 484 is made of a soft rubber material.

[0077] Please also refer to Figure 5 and Figure 8 In some embodiments of the present application, each of the second driving member 44, the wiping rubber head 47 and the clamping assembly 48 is located at the first driving member 43 in the third direction (such as Figure 5 The third direction is perpendicular to the first and second directions. Thus, the second driving member 44, the wiping rubber head 47, and the clamping assembly 48 can be connected to the first driving member 43 via the adapter 45 and located on the same side of the first driving member 43, resulting in a compact structure and reduced space usage.

[0078] See also Figure 8 In some embodiments of the present application, the cleaning and wiping mechanism 4 further includes a connecting sleeve 46 , and the wiping rubber head 47 is connected to the output shaft of the second driving member 44 through the connecting sleeve 46 .

[0079] In this way, it is convenient to connect the wiping rubber head 47 to the output shaft of the second driving member 44. In addition, the cleaning wiping mechanism 4 provided in this application can adjust the distance between the wiping rubber head 47 and the output shaft of the second driving member 44 through the connecting sleeve 46.

[0080] In some embodiments of the present application, a pressure sensor (not shown in the figure) is provided in the wiping rubber head 47, and the pressure sensor is electrically connected to the controller. The controller can adjust the moving distance of the output end of the first driving member 43 according to the pressure measured by the pressure sensor, so that different pressures can be set according to different types of projectors 01.

[0081] In some embodiments of the present application, the first drive member 43 is a servo linear drive module, and the second drive member 44 is a stepper drive motor. A stepper motor is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or advances one step. The angular displacement or linear displacement output is proportional to the number of pulses input, and the rotational speed is proportional to the pulse frequency. In other words, the controller can accurately control the angular displacement and speed of the output shaft of the second drive member 44 by inputting a pulse. In this way, the cleaning and wiping mechanism 4 provided in the present application can accurately control the motion trajectory and wiping rotation speed of the wiping rubber head 47 through the first drive member 43 and the second drive member 44.

[0082] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
