DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0021] The mobile phone screen cleaning device described in this embodiment cleans the mobile phone screen through the dust sticking mechanism 300, and adjusts the moving direction of the dust sticking paper tape through the paper tape adjustment mechanism 200, thereby, on the one hand, enabling the dust sticking roller 310 to be cleaned during the reciprocating movement, and on the other hand, enabling the dust sticking paper tape 400 to be reused under different cleaning requirements. Based on the above design, compared with the current conventional mobile phone screen cleaning technology, the present application does not need to frequently replace the paper tape, thereby having significant advantages such as reducing costs, facilitating operation and adjustment, having a wide range of applications, and having a high degree of adjustment flexibility.

[0022] It should be noted that, for ease of expression, this embodiment defines the length direction of the mobile phone screen to be cleaned as the first direction X, the width direction of the mobile phone screen to be cleaned as the second direction Y, and the height direction of the mounting plate 100 as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicular to each other in pairs, and the first direction X and the second direction Y are located in the same plane.

[0023] In this embodiment, the mounting plate 100 can be connected to an external mounting surface, and is used to provide an installation and connection platform for the paper tape adjustment mechanism 200 and the dust sticking mechanism 300; the dust sticking mechanism 300 is used to contact the mobile phone screen to be cleaned through the dust sticking roller 310, and to adhere and clean the pollutants on it; the dust sticking mechanism 300 is used to adhere the pollutants on the dust sticking roller 310 through dust sticking paper, so as to clean the dust sticking roller 310 and facilitate the centralized recovery of pollutants.

[0024] See also Figure 1 As shown, in this embodiment, the unwinding shaft 210 is arranged at the upper right part of the mounting plate 100, and the reeling shaft 220 is arranged at the lower left part of the mounting plate 100, wherein the reeling shaft 220 and the unwinding shaft 210 can be adjusted independently, wherein the unused sticky paper tape 400 is wound on the unwinding shaft 210, and the used sticky paper tape is wound on the reeling shaft 220. Further, in this embodiment, two abutting shafts 230 are arranged at intervals along the first direction X in the same horizontal plane, and the abutting shafts 230 are used to increase the contact area between the sticky paper tape 400 and the sticky roller 310, so that it can fully remove impurities on the sticky roller 310. In different embodiments, different numbers of sticky rollers 310 can be set according to actual use requirements, and the sticky rollers 310 can also be set at different positions, and the present invention does not make specific restrictions on this.

[0025] Furthermore, since the used sticky paper tape 400 needs to be reused, it is not convenient to directly wind the part of the sticky paper tape 400 that can be reused on the reel 220, otherwise the reuse rate of the paper tape will be reduced due to cross contamination. Based on this, the present application adjusts the moving direction of the sticky paper tape 400 by adjusting the shaft 260 in cooperation with the unwinding shaft 210, thereby, on the one hand, increasing the spacing distance between the sticky paper tape 400 and the rewinding wheel to avoid cross contamination between the sticky paper tape 400, and on the other hand, it can also improve the adjustment flexibility and adjustment accuracy of the sticky paper tape 400. Specifically, the adjustment shaft 260 in this embodiment can change the length of the sticky paper tape 400 that is separated from the unwinding shaft 210 by lifting and lowering, thereby realizing the reciprocating movement process of the sticky paper tape 400 in the first direction X.

[0026] In this embodiment, in order to improve the tension between the sticky paper tape 400 and the adjustment shaft 260, the paper tape adjustment mechanism 200 in this embodiment further includes two limit shafts 240, which are symmetrically arranged on opposite sides of the adjustment shaft 260 along the first direction X, and are located above the adjustment shaft 260 in the height direction of the mounting plate 100, so that the sticky paper tape 400 is in an "M"-shaped bending structure between the limit shaft 240 and the adjustment shaft 260. Based on this, Figure 1 The mobile phone screen cleaning device shown is a reference. When the adjustment shaft 260 descends, the sticky paper tape 400 located at the abutment shaft 230 can move along the first direction X toward the winding shaft 220; conversely, when the adjustment shaft 260 rises, the sticky paper tape 400 located at the abutment shaft 230 can move along the first direction X toward the unwinding shaft 210.

[0027] Specifically, see Figures 1 to 3 As shown, the paper tape adjustment mechanism 200 in this embodiment also includes a first adjustment component 250, which is used to provide a platform for the lifting and moving of the adjustment shaft 260. Further, the adjustment shaft 260 is lifted and moved by the first adjustment component 250. The first adjustment component 250 includes a first lifting module 251 and a first slide plate 252, wherein the first lifting module 251 is arranged on the mounting plate 100 and extends along the height direction of the mounting plate 100, the first slide plate 252 is slidably connected to the first lifting module 251, and the adjustment shaft 260 is fixedly connected to the first slide plate 252 and moves synchronously with the first slide plate 252. The first lifting module 251 is preferably a slide rail, and the first slide plate 252 can be embedded in the slide rail and drive the adjustment shaft 260 to move through electromagnetic control.

[0029] Specifically, in this embodiment, the dust sticking mechanism 300 also includes a second adjustment component 320, and the two dust sticking rollers 310 are moved by the second adjustment component 320. The second adjustment component 320 includes a second lifting module 321 and a second slide plate 322, wherein the second lifting module 321 is arranged on the mounting plate 100 and extends along the height direction of the mounting plate 100, and the second slide plate 322 is slidably connected to the second lifting module 321, and the dust sticking roller 310 is fixedly connected to the second slide plate 322 and moves synchronously with the second slide plate 322. Specifically, the second adjustment component 320 in this embodiment has the same driving principle as the first adjustment component 250, and no further elaboration is made here.

[0030] Furthermore, the paper tape adjustment mechanism 200 in this embodiment also includes a third slide plate 270, which is arranged above the second slide plate 322 and is slidably connected to the second lifting module 321, and the at least one abutment shaft 230 is fixedly connected to the third slide plate 270 and moves synchronously with the third slide plate 270.

[0031] See also Figure 4 As shown, in order to limit the movement degree of the dust-sticking roller 310 and ensure that there is a stable pressure between it and the mobile phone screen to be cleaned without causing squeezing damage to the mobile phone screen, the dust-sticking mechanism 300 in this embodiment also includes a pressure sensing component 330, and the pressure sensing component 330 includes a pressure sensor 333, a fixed frame 331 and a movable frame 336, wherein the fixed frame 331 is arranged on the mounting plate 100, and the movable frame 336 is supported on the third slide plate 270 by a first elastic member 334, and one side of the pressure sensor 333 is connected to the fixed frame 331 by a second elastic member 335, and the other side is connected to the movable frame 336. Specifically, when contact and extrusion occur between the sticky roller 310 and the screen to be cleaned, the first elastic member 334 and the second elastic member 335 can both be in a compressed state, which on the one hand provides sufficient cleaning pressure to the sticky roller 310, and on the other hand buffers the extrusion process to protect the mobile phone screen. In addition, it can also enable the sticky roller 310 to have an automatic reset effect.

[0032] Specifically, the fixed frame 331 in this embodiment is fixedly connected to the mounting plate 100, and the movable frame 336 is used to realize the connection and installation of the pressure sensor 333.
