[0027] See also Figure 1 As shown, according to one aspect of an embodiment of the utility model, a leveling mechanism is provided, comprising a wiping component 1, a connecting plate 2 and at least two adjusting knobs 3, the middle portion of the wiping component 1 is rotatably connected to the connecting plate 2 via a rotating connector 4, at least two adjusting knobs 3 are relatively arranged on the connecting plate 2 along the length direction of the connecting plate 2, and are located on both sides of the rotating connector 4, and the driving ends of at least two adjusting knobs 3 are arranged toward the wiping component 1, and are used to drive the wiping component 1 to rotate with the rotating connection point between the wiping component 1 and the connecting plate 2 as the rotation center. By arranging the adjusting knobs 3 on both sides of the rotating connection point between the wiping component 1 and the connecting plate 2, the wiping component 1 can be driven to rotate relative to the connecting plate 2, so that the wiping component 1 is relatively parallel to the panel to be cleaned, thereby improving the fit between the working surface of the wiping component 1 and the surface of the panel to be cleaned, ensuring that the panel wiping device completely wipes the panel to be cleaned, and improving the cleanliness of the panel to be cleaned.

[0028] The leveling mechanism can be applied to the panel wiping device to adjust the wiping component 1 so that it is relatively parallel to the panel to be cleaned.

[0029] The wiping component 1 may be a sponge, a wiping cloth, a cleaning brush or a scraper.

[0030] The panel to be cleaned may be a mobile phone screen, a watch screen, an electrical appliance control panel or an instrument operation panel, etc.

[0031] Among them, the leveling mechanism includes a connecting plate 2, which is arranged between the driving mechanism of the panel wiping device and the wiping component 1. One side of the connecting plate 2 is used to connect the driving mechanism of the panel wiping device, and the other side is used to connect the wiping component 1, so that the driving mechanism of the panel wiping device can drive the wiping component 1 to move along the set trajectory to achieve the purpose of wiping the panel to be cleaned.

[0032] The wiping component 1 is rotatably connected to the connecting plate 2 via a rotating connector 4 . Specifically, the wiping component 1 is mounted on the connecting plate 2 in a pivotally connected manner, so that the wiping component 1 can rotate relative to the connecting plate 2 .

[0033] Specifically, the pivot is a rotation connection point between the wiping component 1 and the connecting plate 2. The pivot is disposed in the middle of the wiping component 1. The wiping component 1 is suitable for rotating around the pivot as a rotation center.

[0034] The connecting plate 2 and the wiping component 1 extend in the same direction.

[0035] Among them, at least two adjusting knobs 3 are arranged on the connecting plate 2 , and the at least two adjusting knobs 3 are arranged opposite to each other along the length direction of the connecting plate 2 and are respectively located on both sides of the rotating connecting member 4 .

[0036] The driving ends of at least two adjusting knobs 3 are arranged toward the wiping member 1, and the at least two adjusting knobs 3 are used to drive the wiping member 1 to rotate with the rotating connecting member 4 as the rotation center and be fixed at a preset angle, so as to achieve the purpose of adjusting the wiping member 1 to be relatively parallel to the panel to be cleaned. It can be understood that the preset angle can be the angle between the wiping member 1 and the connecting member when the wiping member 1 is relatively parallel to the panel to be cleaned.

[0037] Specifically, at least two adjusting knobs 3 cause the wiping component 1 to rotate by pressing the wiping component 1. In the embodiment of the utility model, the at least two adjusting knobs 3 include a first adjusting knob and a second adjusting knob, and when the driving end of the first adjusting knob is extended, the driving end of the second adjusting knob is shortened; when the driving end of the first adjusting knob is shortened, the driving end of the second adjusting knob is extended.

[0038] As one embodiment, at least two adjusting knobs 3 directly press the wiping component 1; as another embodiment, at least two adjusting knobs 3 indirectly press the wiping component 1. In the embodiment of the utility model, the wiping component 1 is arranged on the bottom surface of the connecting plate 2, at least two adjusting knobs 3 are fixedly mounted on the side surface of the connecting plate 2 through the mounting plate, and at least two adjusting knobs 3 indirectly press the wiping component 1 by pressing the top block 51 of the transmission plate 5.

[0039] In some possible implementations provided by the present invention, see Figure 1 As shown, at least two adjusting knobs 3 are equidistant from the rotating connection member 4 .

[0040] When at least two adjusting knobs 3 are at an equal distance from the rotating connector 4, the leveling mechanism is a symmetrical structure, and the center of symmetry is the rotating connector 4. By setting the leveling mechanism to a symmetrical structure, shaking and unstable factors can be reduced during the operation of the wiping component 1, ensuring the stability of the panel wiping device; at the same time, it helps to achieve the leveling function more accurately, and the symmetrical structure makes it easier to ensure the accuracy and consistency of the adjustment.

[0041] In some possible embodiments provided by the present invention, the adjustment knob 3 includes a screw, a fixed sleeve and a movable sleeve, the screw is telescopically arranged in the fixed sleeve, the movable sleeve is sleeved outside the fixed sleeve, the movable sleeve is relatively fixed to the screw, and the outer wall of the fixed sleeve is marked with integer scales along the length direction of the fixed sleeve. By marking integer scales on the outer wall of the fixed sleeve along the telescopic direction of the screw, the telescopic amount of the screw is visualized, that is, the adjustment amount of the wiping component 1 is visualized, thereby reducing the difficulty of leveling the wiping component 1 and the panel to be cleaned, and improving the debugging efficiency of the panel wiping equipment.

[0042] The driving end of the adjusting knob 3 may be a screw rod, and the screw rod is movably disposed in the fixed sleeve.

[0043] Specifically, the driving end of the adjusting knob 3 is extended, that is, the screw moves in a direction extending from the fixed sleeve; the driving end of the adjusting knob 3 is shortened, that is, the screw moves in a direction retracting into the fixed sleeve.

[0044] The fixing sleeve is fixed relative to the mounting plate so that the adjusting knob 3 can be mounted on the mounting plate.

[0045] The fixing sleeve is substantially cylindrical, and the axial direction of the fixing sleeve may be the extension and retraction direction of the screw rod.

[0046] The movable sleeve is sleeved on one end of the fixed sleeve away from the wiping component 1 . The movable sleeve is slidably arranged on the outer wall of the fixed sleeve. The movable sleeve is suitable for moving along the axial direction of the fixed sleeve.

[0047] Specifically, the screw and the movable sleeve are relatively fixed, and the movable sleeve can move along the axial direction of the fixed sleeve to drive the screw to extend and retract, so that the wiping component 1 can be quickly adjusted to be relatively parallel to the panel to be cleaned, thereby improving the efficiency of the leveling mechanism.

[0048] The outer wall of the fixed sleeve is marked with integer scales, and the integer scales extend along the axial direction of the fixed sleeve, that is, the extension and retraction direction of the screw rod.

[0049] Specifically, when the movable sleeve slides on the fixed sleeve, it can cover part of the integer scale, and the position of the end of the movable sleeve close to the wiping component 1 on the integer scale is used to characterize the expansion and contraction amount of the bolt. It should be noted that when the wiping component 1 is relatively parallel to the connecting plate 2, the contraction amount of the driving end of at least two adjusting knobs 3 is the same, and the position of the end of the movable sleeve close to the wiping component 1 on the integer scale is the initial scale, that is, the 0 scale.

[0050] Among them, as one implementation mode, the scale value of the initial scale close to the wiping component 1 is a positive value, and the scale value of the initial scale away from the wiping component 1 is a negative value; as another implementation mode, the scale value of the initial scale close to the wiping component 1 is a negative value, and the scale value of the initial scale away from the wiping component 1 is a positive value.

[0051] Specifically, in the embodiment of the utility model, at least two adjusting knobs 3 are at the same distance from the rotating connector 4, and the absolute values ​​of the integer scale readings on at least two adjusting knobs 3 should also be the same. If they are different, it means that at least two adjusting knobs 3 are faulty, and the faults can be verified with each other to eliminate them.

[0052] In some possible embodiments provided by the present invention, the screw rod is connected to the fixed sleeve by a threaded structure, the pitch of the threaded structure is 0.5 mm, and a differential scale is marked on the outer wall of the movable sleeve along the circumferential direction of the fixed sleeve, and the differential scale is used to divide 0.5 mm into 50 equal parts.

[0053] The outer wall of the screw rod is provided with an external thread, the inner wall of the fixed sleeve is provided with an internal thread matched with the external thread of the screw rod, and the screw rod and the fixed sleeve are connected by the external thread and the internal thread.

[0054] Specifically, the screw rod and the fixed sleeve are driven by a threaded structure. In the embodiment of the utility model, when the movable sleeve is screwed, the screw rod moves along the axial direction of the fixed sleeve.

[0055] The pitch of the thread structure is 0.5 mm, that is, when the movable sleeve is turned one circle, the expansion and contraction amount of the screw will change by 0.5 mm.

[0056] Specifically, the outer wall of the movable sleeve is marked with differential scales along the circumferential direction of the movable sleeve, and the differential scales are used to divide 0.5 mm into 50 equal parts, so that the accuracy of the leveling mechanism can be accurate to 0.01 mm, thereby improving the fit between the working surface of the wiping component 1 and the surface of the panel to be cleaned, ensuring that the panel wiping equipment wipes the panel to be cleaned completely, and improving the cleanliness of the panel to be cleaned.

[0057] In some possible implementations provided by the present invention, see Figure 1 As shown, the leveling mechanism further includes a transmission plate 5 , which is disposed between the wiping component 1 and the connecting plate 2 , and the wiping component 1 is rotatably connected to the connecting plate 2 via the transmission plate 5 .

[0058] Among them, in the embodiment of the utility model, the wiping component 1 is rotatably connected to the connecting plate 2 through the transmission plate 5, which is convenient for disassembling and assembling the wiping component 1, and improves the replacement efficiency of the wiping component 1. It should be noted that when the wiping component 1 is rotatably connected to the connecting plate 2 directly, the replacement of the wiping component 1 requires disassembling and assembling the rotating connector 4.

[0059] The transmission plate 5 is arranged on one side of the connecting plate 2 close to the wiping component 1, one side of the transmission plate 5 is used to connect the connecting plate 2, and the other side of the transmission plate 5 is used to connect the wiping component 1. In the embodiment of the utility model, the transmission plate 5 is rotatably connected to the connecting plate 2 through the rotating connector 4, and the wiping component 1 and the transmission plate 5 are relatively fixed.

[0060] Specifically, a second groove is formed on the side of the transmission plate 5 facing away from the connecting plate 2. The second groove may be a rectangular groove, and the second groove extends along the length direction of the wiping component 1. At least part of the wiping component 1 may be embedded in the second groove. It is understandable that when replacing the wiping component 1, the old wiping component 1 can be taken out of the second groove, and then a new wiping component 1 can be put into the second groove, without disassembling the rotating connector 4, thereby improving the replacement efficiency of the wiping component 1.

[0061] In some possible implementations provided by the present invention, see Figure 1 As shown, a first groove is provided on a side of the connecting plate 2 close to the wiping component 1, a transmission plate 5 is arranged in the first groove, a side of the transmission plate 5 close to the adjusting knob 3 has a protruding top block 51, an opening is provided on the side wall of the first groove at a position relative to the top block 51, and the opening is used to pass the top block 51; at least two top blocks 51 are provided, and at least two top blocks 51 are provided in a one-to-one correspondence with at least two adjusting knobs 3; at least two openings are provided, and at least two openings are provided in a one-to-one correspondence with at least two top blocks 51.

[0062] The first groove may also be a rectangular groove, the first groove extends along the length direction of the transmission plate 5, and the transmission plate 5 is arranged in the first groove.

[0063] A top block 51 is provided on one side of the transmission plate 5 close to the adjusting knob 3. The top block 51 is perpendicular to the driving end of the adjusting knob 3. The driving end of the adjusting knob 3 can cause the transmission plate 5 to drive the wiping component 1 to rotate by pressing the top block 51. It should be noted that the driving end of the adjusting knob 3 is located within the projection area of ​​the top block 51.

[0064] There are at least two top blocks 51 , and the at least two top blocks 51 are arranged in one-to-one correspondence with the at least two adjusting knobs 3 .

[0065] The side wall of the first groove is provided with an opening at a position relative to the top block 51, and the opening is generally in a long strip shape, and the opening is used to pass the top block 51. In the embodiment of the utility model, the top block 51 extends out of the first groove through the opening, so that the driving end for adjusting rotation can press the top block 51.

[0066] Specifically, the opening extends along the telescopic direction of the driving end of the adjusting knob 3 to adapt to the rotation of the wiping component 1 .

[0067] There are at least two openings, and the at least two openings are arranged in one-to-one correspondence with the at least two top blocks 51 .

[0068] In some possible implementations provided by the present invention, see Figure 1 As shown, the leveling mechanism also includes a tensioning member 6, which is also arranged in the second groove. The tensioning member 6 is used to compress the wiping component 1 in the second groove to prevent the wiping component 1 from escaping from the second groove during operation, thereby improving the working stability of the panel wiping device.

[0069] Among them, the tensioning member 6 is arranged between the wiping component 1 and the side wall of the second groove. The tensioning member 6 is used to apply pressure to the wiping component 1 toward the side wall of the second groove to increase the friction between the wiping component 1 and the side wall of the second groove to prevent the wiping component 1 from falling out of the second groove.

[0070] There may be one or two expansion members 6 . When there are two expansion members 6 , the two expansion members 6 are arranged on two sides of the wiping component 1 opposite to each other.

[0071] Specifically, when the wiping component 1 is a hard component such as a scraper, the expansion component 6 is arranged in the second groove to achieve an obvious expansion effect; when the wiping component 1 is a flexible component such as a sponge, the expansion component 6 may not be arranged in the second groove.

[0072] In some possible implementations provided by the present invention, see Figure 1 As shown, the rotating connecting member 4 is a rotating shaft, and a retaining spring is sleeved on the shaft end of the rotating shaft.

[0073] In the embodiment of the utility model, the first end of the rotating shaft is rotatably connected to the connecting plate 2 , the second end of the rotating shaft is rotatably connected to the transmission plate 5 , and the wiping component 1 is rotatably connected to the connecting plate 2 via the transmission plate 5 .

[0074] Specifically, an annular groove is formed at the first end and the second end of the rotating shaft, and a retaining spring is disposed in the annular groove. The retaining spring is used to limit the axial displacement of the connecting plate 2 and the transmission plate 5 .

[0075] Another aspect of the embodiments of the present invention provides a panel wiping device, comprising any one of the above-mentioned leveling mechanisms.

[0076] An embodiment of the utility model provides a leveling mechanism and a panel wiping device, wherein the leveling mechanism can drive the wiping component 1 to rotate relative to the connecting plate 2 by arranging adjustment knobs 3 on both sides of the rotation connection point between the wiping component 1 and the connecting plate 2, so that the wiping component 1 is relatively parallel to the panel to be cleaned, thereby improving the fit between the working surface of the wiping component 1 and the surface of the panel to be cleaned, ensuring that the panel wiping device wipes the panel to be cleaned completely, and improving the cleanliness of the panel to be cleaned.

[0077] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0078] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.

The above are only preferred implementations of the present invention.
