[0002] With the development of science and technology, electronic products have become widely popular. People's production and life are inseparable from various electronic devices, such as mobile terminals such as smart phones or tablet computers. The screen of the mobile terminal is an important part of the entire mobile phone, which is easy to damage and expensive. Once it is accidentally dropped, the screen is easy to break, causing great losses to the user. Therefore, there is a need to protect the electronic screen of the mobile device. People usually apply a layer of protective film on the surface of the display screen of mobile terminals such as smart phones or tablet computers to protect the display screen of the mobile terminal and prevent the display screen from being accidentally scratched and cracked. In order to improve the efficiency of film pasting, an automatic film pasting machine can be used instead of manual film pasting.

[0003] Before applying a protective film to the electronic screen of a mobile device, the electronic screen of the mobile device needs to be cleaned to prevent dust, stains and other impurities remaining on the electronic screen from affecting the adhesion of the protective film and affecting the appearance of the protective film. Therefore, a cleaning mechanism for cleaning the electronic screen of the mobile device is usually provided in the automatic film applying machine. The current cleaning mechanism usually only uses a brush to directly brush the electronic screen of the mobile device. It is difficult to remove some stains with strong adhesion, and the cleaning effect is poor. In addition, some residual impurities are likely to appear after cleaning with the brush.

[0030] See also Figure 1An embodiment of the present invention provides a screen cleaning mechanism of a mobile terminal film laminating machine, comprising: a bracket 10, a cleaning liquid spraying module 20, a light sweeping module 30, a wiping module 40 and a mobile terminal placement platform 50. In this embodiment, since the cleaning liquid spraying module 20, the light sweeping module 30 and the wiping module 40 are arranged, in order to facilitate the movement of the mobile terminal on the bracket 10, a cleaning channel 11 for the mobile terminal to pass through is formed on the bracket 10, and the positions of the cleaning liquid spraying module 20, the light sweeping module 30 and the wiping module 40 relative to the cleaning channel 11 can be designed according to actual needs. In this embodiment, the wiping module 40, the cleaning liquid spraying module 20 and the sweeping module 30 are sequentially arranged along the extension direction of the cleaning channel 11. Of course, the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40 may also be sequentially arranged along the extension direction of the cleaning channel 11, or the wiping module 40, the sweeping module 30 and the cleaning liquid spraying module 20 may also be sequentially arranged along the extension direction of the cleaning channel 11, and this example is not limited. Of course, in some other optional embodiments, the cleaning liquid spraying module 20 and / or the wiping module 40 may not be provided.

[0031] See also Figure 2 The cleaning liquid spraying module 20 includes a spraying head 21 and a cleaning liquid delivery module 22. The spraying head 21 is arranged on the bracket 10, and the cleaning liquid delivery module 22 is connected to the injection module. In the present embodiment, the spraying head 21 is directed into the cleaning channel 11, so as to facilitate the spraying of the cleaning liquid on the screen. Of course, the cleaning liquid spraying module 20 is not necessary, and the cleaning liquid can also be sprayed on the screen by the user, and then cleaned by the screen cleaning mechanism of the mobile terminal film laminating machine. Alternatively, it is also feasible not to spray the cleaning liquid.

[0032] The sweeping module 30 includes a cleaning component 31 and a rotating drive component 32. The rotating drive component 32 is arranged on the bracket 10 and is drivingly connected to the cleaning component 31. The cleaning component 31 is configured to clean and polish the screen under the drive of the rotating drive component 32. The cleaning and polishing have strong force and can perfectly remove impurities on the screen, achieving a good cleaning effect.

[0033] The wiping module 40 is disposed on the bracket 10 and is used to wipe the screen of the mobile terminal. In this embodiment, at least part of the wiping module 40 extends into the cleaning channel 11. Of course, the wiping module 40 is not necessary, and it is also feasible not to set the wiping module 40.

[0034] The rotation driving component 32 may be a component capable of driving rotation, such as a motor.

[0035] The mobile terminal placement platform 50 is used to place the mobile terminal, and the bracket 10 is arranged above the mobile terminal placement platform 50. The cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40 can move relative to the mobile terminal placement platform 50, so that the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40 approach or move away from the mobile terminal placement platform 50 or move on the mobile terminal placement platform 50. In some embodiments, the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40 are capable of moving relative to the mobile terminal placement platform 50. After the mobile terminal is placed on the mobile terminal placement platform 50, the cleaning component 31 of the sweeping module 30 moves back and forth relative to the screen of the mobile terminal, and the cleaning liquid spraying module 20 and the wiping module 40 can also be actively moved to a position suitable for processing the mobile terminal screen; of course, the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40 can also be fixed, and the mobile terminal placement platform 50 can move back and forth relative to the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40, so that the screen of the mobile terminal can be processed by the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40. In the present embodiment, the mobile terminal placement platform 50 and the scanning module 30 are movable, so that the mobile terminal placement platform 50 can adjust the position of the mobile terminal to be swept back and forth by the scanning module 30, thereby avoiding the situation where the cleaning component 31 may be too small to completely clean all positions of the screen. Moreover, the mobile terminal placement platform 50 can also drive the mobile terminal to move to the wiping module 40 and the cleaning liquid spraying module 20, so as to facilitate the wiping and spraying of the cleaning liquid on the mobile terminal.

[0036] The specific structure of the mobile terminal placement platform 50 can be designed according to actual needs. For example, when the mobile terminal placement platform 50 does not need to move, it can only be a support table that can support the mobile terminal. Alternatively, the mobile terminal placement platform 50 includes a mobile terminal shaping mechanism 51, which not only supports the mobile terminal, but also clamps and positions the mobile terminal. Of course, when the mobile terminal placement platform 50 needs to move, the mobile terminal shaping mechanism 51 is also connected to a conveying mechanism 60, which is arranged on the bracket 10 and is driven and connected to the mobile terminal shaping mechanism 51. The mobile terminal is placed on the mobile terminal shaping mechanism 51, and the conveying mechanism 60 drives the mobile terminal shaping mechanism 51 to move in the cleaning channel 11, so that the mobile terminal is moved to the cleaning liquid spraying module 20, the sweeping module 30 and the wiping module 40 in sequence, thereby achieving cleaning. The conveying mechanism 60 can be a belt conveying mechanism 60 or a screw conveying mechanism 60, etc., which can drive the mobile terminal shaping mechanism 51 to move.

[0037] The specific structure of the mobile terminal shaping mechanism 51 can be designed according to actual needs. For example, the mobile terminal shaping mechanism 51 may include a shaping seat and a clamping assembly. The shaping seat is provided with a shaping groove for placing the mobile terminal. The clamping assembly includes a clamping part, a first translation driving assembly and two inclined positioning parts. The two inclined positioning parts and the clamping part are relatively arranged in the shaping groove. A positioning space for placing the mobile terminal is formed between the two inclined positioning parts and the clamping part. The angle formed by the extension directions of the two inclined positioning parts is greater than 0° and less than 180°. The first translation driving assembly is drivingly connected to the clamping part and / or the inclined positioning part, and is used to drive the clamping part and the inclined positioning part to move closer to or away from each other to clamp or release the mobile terminal. When clamping the mobile terminal, the two inclined positioning parts respectively rest against two adjacent corners on one side of the mobile terminal, and the clamping part presses toward the mobile terminal from the other opposite side to press the mobile terminal toward the two inclined positioning parts to achieve triangular positioning. In some optional embodiments, the cleaning liquid delivery module 22 includes a liquid storage tank 221 and an air pump 222, which are arranged on the bracket 10 and are both connected to the spray head 21. When it is necessary to spray the cleaning liquid, the air pump 222 is started and generates a high-speed airflow. When the airflow passes through the spray head 21, a negative pressure will be generated at the connection between the liquid storage tank 221 and the spray head 21, thereby driving the cleaning liquid in the liquid storage tank 221 to enter the spray head 21, and then the cleaning liquid is mixed with the high-speed airflow and sprayed out from the spray head 21. This design is conducive to controlling the spraying of a relatively appropriate amount of cleaning liquid due to the relatively small amount of cleaning liquid sprayed per unit time, and avoiding spraying too much cleaning liquid at a single time. Of course, the structure of the cleaning liquid delivery module 22 is not limited to this, and those skilled in the art can also select other suitable structures according to the teachings of the present invention.

[0038] In some optional embodiments, the cleaning component 31 includes a connecting seat 311 and a cleaning structure 312. The connecting seat 311 is connected to the rotating drive component 32. Since the cleaning structure 312 is usually a flexible and elastic structure, the connecting seat 311 facilitates the connection between the cleaning structure 312 and the rotating drive component 32. The cleaning structure 312 is arranged on the connecting seat 311. The cleaning structure 312 is a brush or a cleaning cloth. Of course, the cleaning structure 312 may also adopt other suitable practical structures, not limited to the form of a brush or cloth.

[0039] See also Figure 3In some optional embodiments, the cleaning component 31 is detachably connected to the rotating drive component 32, so as to facilitate the maintenance and replacement of the cleaning component 31 and avoid the need to replace the entire cleaning component when the cleaning component 31 is damaged. The detachable connection method of the cleaning component 31 and the rotating drive component 32 can select a suitable design according to actual needs. For example, in this embodiment, a protruding buckle portion 313 is provided on the connecting seat 311 of the cleaning component 31, and a connecting block 321 is provided on the output shaft of the rotating drive component 32. A buckle groove 322 is provided on the connecting block 321, and the buckle portion 313 is buckled with the buckle groove 322. Alternatively, a clamping hole is provided on the connecting seat 311 of the cleaning component 31, and the output shaft of the rotating drive component 32 is clamped into the clamping hole, or a connecting disk is provided on the output shaft of the rotating drive component 32, and the connecting disk is detachably fixed to the cleaning component 31 through a screw.

[0040] The light sweeping module 30 can adopt passive cleaning and active cleaning. Passive cleaning means that the screen passes through the light sweeping module 30 back and forth under the drive of other structures, so that different positions of the screen are cleaned by the light sweeping module 30. Active cleaning means that after the screen moves to the light sweeping module 30, the light sweeping module 30 moves back and forth to clean the screen. When the light sweeping module 30 adopts active cleaning, in some optional embodiments, the light sweeping module 30 also includes a mounting seat 33 and a reciprocating moving component 34. The mounting seat 33 is movably arranged on the bracket 10. The reciprocating moving component 34 is connected to the mounting seat 33 for driving the mounting seat 33 to move back and forth. The rotating driving component 32 is arranged on the mounting seat 33. The reciprocating moving component 34 drives the mounting seat 33 to move back and forth, thereby driving the rotating driving component 32 and the cleaning component 31 to move back and forth, thereby cleaning and polishing the screen.

[0041] After the cleaning component 31 brushes the screen, impurities such as waste liquid, stains, and dust may adhere to the cleaning component 31. In order to prevent the cleaning component 31 from contaminating the screen that is subsequently cleaned, in some optional embodiments, the light sweeping module 30 also includes a cleaning chamber 35, which is arranged on the moving path of the cleaning component 31. A scraper 351 is provided in the cleaning chamber 35. The reciprocating moving component 34 can drive the mounting seat 33 to move to the cleaning chamber 35 so that the cleaning structure 312 of the cleaning component 31 extends into the cleaning chamber 35. The cleaning component 31 rotates in the cleaning bin 35, so that the cleaning component 31 scrapes on the scraper 351, and then the waste liquid, stains, dust and other impurities adhering to the cleaning component 31 are scraped off from the cleaning component 31 by the scraper 351, thereby cleaning the cleaning component 31, and the waste liquid, stains, dust and other impurities can be attached to the scraper 351, and due to the gravity of the waste liquid, the waste liquid, stains, dust and other impurities can fall to the bottom of the cleaning bin 35 along with the scraper 351.

[0042] In some optional embodiments, the scanning module 30 also includes two sensing components 36, which are arranged on the bracket 10 and are connected to the reciprocating moving component 34 by signal. The mounting seat 33 is located between the two sensing components 36. When the mounting seat 33 approaches or abuts against the sensing component 36 under the drive of the reciprocating moving component 34, the mounting seat 33 and the sensing component 36 are inductively matched. At this time, the sensing component 36 generates a sensing signal and sends the sensing signal to the reciprocating moving component 34. The reciprocating moving component 34 stops driving the mounting seat 33 to move, thereby facilitating accurate control of the position of the mounting seat 33, and then accurately controlling the position of the cleaning component 31.

[0043] In this embodiment, a sensing sheet that senses and cooperates with the sensing component 36 is provided on the mounting seat 33. When the cleaning component 31 on the mounting seat 33 moves to the cleaning chamber 35, one of the sensing components 36 senses and cooperates with the sensing sheet.

[0044] The specific structure of the sensing component 36 can be designed according to actual needs. For example, the sensing component 36 can be a proximity switch, an infrared sensor, a photoelectric sensor, etc. At this time, the mounting base 33 only needs to be close to the sensing component 36 to trigger the sensing component 36. Of course, the sensing component 36 can also use a travel switch, etc.

[0045] The wiping module 40 can adopt passive cleaning and active cleaning. Passive cleaning means that the screen passes through the wiping module 40 back and forth under the drive of other structures, so that different positions of the screen are cleaned by the wiping module 40. Active cleaning means that after the screen moves to the wiping module 40, the wiping module 40 moves back and forth to clean the screen. In this embodiment, the wiping module 40 adopts a passive cleaning method.

[0046] The specific structure of the wiping module 40 can be designed according to actual needs. For example, the wiping module 40 includes a wiping block fixed in the cleaning channel 11, and a cloth is arranged on the wiping block. When the screen of the mobile terminal passes through the wiping block, the cloth will wipe the screen of the mobile terminal. In this embodiment, the wiping module 40 includes a storage roller 41, a waste roller 42, a pressure roller 43, a wiping cloth 44 and a power module 45. The storage roller 41, the waste roller 42 and the pressure roller 43 are all rotatably arranged on the bracket 10, the pressure roller 43 is located in the cleaning channel 11, the wiping cloth 44 is wound on the storage roller 41, and part of the wiping cloth 44 bypasses the bottom of the pressure roller 43 and is then connected to the waste roller 42. The power module 45 is drivingly connected to the storage roller 41 and / or the waste roller 42. After the screen of the mobile terminal is cleaned by the scanning module 30, the mobile terminal moves to the wiping module 40, and the screen of the mobile terminal is abutted against the wiping cloth 44 located at the bottom of the pressure roller 43, and then the mobile terminal continues to move, so that the wiping cloth 44 wipes the screen. After wiping is completed, the power assembly drives the storage roller 41 and / or the waste roller 42 to rotate, thereby driving the wiping cloth 44 to move a preset distance toward the waste roller 42, so that the used wiping cloth 44 located at the bottom of the pressure roller 43 moves toward the waste roller 42 and leaves the bottom of the pressure roller 43, and the new unused wiping cloth 44 comes to the bottom of the pressure roller 43 for the next screen wiping.

[0047] The power assembly may be connected to the storage roller 41 and / or the waste roller 42. When the power assembly is connected to the storage roller 41 but not to the waste roller 42, when the power assembly drives the storage roller 41 to rotate to output the wiping cloth 44, the wiping cloth 44 between the pressing roller 43 and the storage roller 41 may be bent due to the friction, thereby preventing the new unused wiping cloth 44 from reaching the bottom of the pressing roller 43. In this embodiment, the power assembly is connected to the waste roller 42, thereby facilitating the tightening of the wiping cloth 44 between the waste roller 42 and the storage roller 41, thereby facilitating the complete driving of the used wiping cloth 44 at the bottom of the pressing roller 43 to completely leave the bottom of the pressing roller 43.

[0048] The specific structure of the power module 45 can be designed according to actual needs. For example, the power module 45 may include a motor and a synchronous belt assembly. The motor is arranged on the bracket 10 and is connected to the waste roller 42 through the synchronous belt assembly. Of course, the power module 45 may also include a drive motor, and the output shaft of the drive motor is connected to the waste roller 42.

[0049] See also Figure 4In some optional embodiments, the pressure roller 43 is liftably arranged on the bracket 10, and an elastic member 46 is connected between the pressure roller 43 and the bracket 10. When the screen of the mobile terminal reaches below the pressure roller 43, the pressure roller 43 rises due to the squeezing of the mobile terminal. When the pressure roller 43 rises, the elastic member 46 produces elastic deformation. The elastic force of the elastic member 46 will drive the pressure roller 43 to press down, so that the pressure roller 43 presses the wiping cloth 44 against the screen of the mobile terminal, so that when the mobile terminal moves, the screen can move relative to the wiping cloth 44, thereby achieving a wiping effect.

[0050] The specific structure of the elastic member 46 can be designed according to actual needs. For example, the pressure roller 43 can be lifted and lowered on the bracket 10 through a lifting seat. The pressure roller 43 rotates and cooperates with the lifting seat. A guide rail or a guide column is provided on the bracket 10. The lifting seat slides and cooperates with the guide rail or the guide column. A spring is provided between the lifting seat and the bracket 10. When the pressure roller 43 rises, the lifting seat is driven to rise, and the lifting seat will squeeze the spring. Alternatively, in this embodiment, two guide grooves 12 are provided on the bracket 10. The two ends of the pressure roller 43 rotate and cooperate with the guide grooves 12 respectively, and can be lifted and lowered along the guide grooves 12. The elastic member 46 includes two torsion springs. The torsion spring is provided on the bracket 10. One leg of the torsion spring is connected to the bracket 10, and the other leg abuts against the pressure roller 43. When the pressure roller 43 rises, the leg will be driven to bend, thereby causing the torsion spring to produce elastic deformation.

[0051] In order to facilitate tightening the wiping cloth 44, in some optional embodiments, the wiping module 40 also includes two clamping rods 47, which are rotatably set on the bracket 10, and the two clamping rods 47 are arranged side by side between the waste roller 42 and the waste roller 42. Part of the wiping cloth 44 bypasses the pressure roller 43 in sequence, passes between the two clamping rods 47, and is connected to the waste roller 42. The guide roller 48 and the clamping rod 47 are helpful for tightening the wiping cloth 44, so that when the wiping cloth 44 wipes the screen of the mobile terminal, the wiping cloth 44 is not easy to shake and shift its position, causing the wiping cloth 44 to slide relative to the screen, affecting the wiping effect. In addition, when the power assembly is connected to the waste roller 42 drive, if the waste roller 42 pulls the wiping cloth 44 to move, the two clamping rods 47 are conducive to clamping the wiping cloth 44 to provide a certain resistance for the wiping cloth 44, thereby improving the effect of straightening the wiping cloth 44, and if the waste roller 42 rotates and causes the wiping cloth 44 to retreat, due to the arrangement of the clamping rods 47, when the wiping cloth 44 retreats, it will only cause the wiping cloth 44 between the clamping rods 47 and the waste roller 42 to bend, while the wiping cloth 44 between the clamping rods 47, the pressure roller 43 and the storage roller 41 is still in a taut state.

[0052] In some optional embodiments, the wiping module 40 further includes two guide rollers 48 , which are respectively disposed between the pressure roller 43 and the waste roller 42 and between the clamping roller 47 and the waste roller 42 , for guiding the movement of the wiping cloth 44 and facilitating the straightening of the wiping cloth 44 .

[0053] The specific structure of the reciprocating assembly 34 can be designed according to actual needs. For example, the reciprocating assembly 34 can be a screw drive assembly, a rotary motor reciprocating assembly 34, a belt reciprocating assembly 34, a cylinder reciprocating assembly 34 or a linear motor reciprocating assembly 34.

[0054] In this embodiment, the process of cleaning the screen of the mobile terminal is described in the case where a cleaning liquid spraying module 20, a light sweeping module 30 and a wiping module 40 are arranged: the mobile terminal first enters the cleaning channel 11, and then moves to the bottom of the spray head 21. The cleaning liquid delivery module 22 delivers the cleaning liquid to the spray head 21, and the spray head 21 sprays the cleaning liquid on the screen. The cleaning liquid is convenient for removing dust on the screen and can dissolve some attached stains, especially for some grease that is difficult to remove. It also has a good cleaning effect. Then the mobile terminal moves to the light sweeping module 30, and the cleaning component 31 cleans and polishes the screen under the drive of the rotating drive component 32, so that the stubborn stains on the screen can be well removed. Finally, the mobile terminal moves to the wiping module 40, and the screen is wiped by the wiping module 40, so that the residual cleaning liquid and / or impurities on the screen are removed, achieving a good cleaning effect.
