[0024] Reference below Figures 1 to 3 A cleaning device according to an embodiment of the first aspect of the present invention is described.

[0025] like Figure 1 and Figure 3 As shown, the cleaning device can clean the curved screen through a flexible cleaning member, and includes a contoured cleaning head 310 and a first driving device 600. Figure 3As shown, a cavity is provided on the contour cleaning head 310, and the cavity is used to accommodate at least part of the portion to be cleaned of the curved screen. It can be understood that the cavity is used to accommodate part of the portion to be cleaned of the curved screen or the cavity accommodates all the portions to be cleaned of the curved screen. In this embodiment, the curved screen is specifically a curved screen of a mobile phone, and the bottom surface of the cavity of the contour cleaning head 310 includes a plane 312 and an arc surface 311, and the arc surface 311 is located on both sides of the plane 312. The flexible cleaning member is placed between the curved screen and the contour cleaning head 310, and the contour cleaning head 310 is used to make the flexible cleaning member contact the portion to be cleaned of the curved screen. The first driving device 600 is used to drive the relative movement between the flexible cleaning member and the curved screen. The relative movement between the flexible cleaning member and the curved screen can be achieved in the following ways: the curved screen can be placed in a fixed position, and the first driving device 600 drives the flexible cleaning member and the contoured cleaning head 310 to move simultaneously, so that the flexible cleaning member and the curved screen can move relative to each other; the curved screen and the contoured cleaning head 310 can be placed in fixed positions, and the first driving device 600 drives the flexible cleaning member to move, so that the flexible cleaning member moves relative to the curved screen; the contoured cleaning head 310 and the flexible cleaning member can also be placed in fixed positions, and the first driving device 600 drives the curved screen to move, so that the curved screen moves relative to the flexible cleaning member. The flexible cleaning member in this embodiment can be a dust-free wiping cloth, which has a good dust removal effect and will not damage the surface of the curved screen. The dust-free wiping cloth can be an ordinary dust-free cloth or a microfiber dust-free cloth.

[0026] In some specific embodiments of the present invention, the cleaning device further includes a retracting device 200. The retracting device 200 includes a material discharging assembly 210, a material collecting assembly 220 and a material collecting motor 230. The material discharging assembly 210 is used to release the flexible cleaning member, and the material collecting assembly 220 is used to retract the flexible cleaning member. The material collecting motor 230 is used to drive the material collecting assembly 220 to move, so that the material collecting assembly moves to retract the flexible cleaning member. The cavity of the contoured cleaning head 310 accommodates all the parts of the curved screen to be cleaned, and the first driving device 600 drives the material discharging assembly 210 and the material collecting assembly 220 to move synchronously relative to the curved screen, so that the flexible cleaning member moves relative to the curved screen.

[0027] In some specific embodiments of the present invention, the cleaning device further comprises a frame 100, such as Figure 1The frame 100 shown has a back plate, a top plate, two side plates and a bottom plate. The back plate, the top plate, the two side plates and the bottom plate form a cavity. The material discharge assembly 210, the material receiving assembly 220 and the contour cleaning head 310 are all fixedly connected to the frame 100, and the specific fixed connection method is: the material discharge assembly 210 and the material receiving assembly 220 are placed in the cavity and installed on the back plate, and the cleaning head assembly 300 includes a contour cleaning head 310 and a mounting plate 320, and the contour cleaning head 310 is fixedly connected to the frame 100 through the mounting plate 320. The contour cleaning head 310 is detachably mounted on the mounting plate 320, which is convenient for cleaning, repairing or replacing the contour cleaning head 310. The contour cleaning head 310 of the same model can be replaced; it can also be replaced with a contour cleaning head 310 of a different model, so that the cleaning device can clean more curved screens of different sizes only when the contour cleaning head 310 is replaced, thereby improving the versatility of the cleaning device. It is understandable that the contoured cleaning head 310 and the mounting plate 320 can be installed by threaded connection, snap connection or adsorption.

[0028] In some specific embodiments of the present invention, the dust-free cloth can usually be replaced after multiple uses. In order to make full use of the dust-free cloth and replace it in time, a sensor 500 is provided on the frame 110 to record the number of relative movements between the flexible cleaning member and the curved screen. A replacement threshold is set according to the cleaning force of the flexible cleaning member, and the data detected by the sensor 500 is compared with the replacement threshold to determine whether to replace the flexible cleaning member. When the flexible cleaning member needs to be replaced, the receiving motor 230 is controlled to work, and the receiving motor 230 drives the receiving assembly 220 to rotate to retract the dirty flexible cleaning member, and at the same time drives the discharging assembly 210 to work to release the clean flexible cleaning member, thereby realizing the automatic replacement of the flexible cleaning member. Through the use of the sensor 500, the flexible cleaning member can be fully utilized and replaced in time, which can save costs and ensure the cleaning effect, and facilitate the realization of automatic film application. The transmission mechanism between the receiving motor 230 and the receiving assembly 220 can be as follows Figure 2 The belt transmission mechanism shown may also be other transmission mechanisms in the art, such as a gear transmission mechanism, a chain transmission mechanism, etc.

[0029] During the replacement of the flexible cleaning member, in order to guide the flexible cleaning member, such as Figure 2 As shown, guide rollers 400 are provided on the left and right sides of the contoured cleaning head 310. In addition to guiding the flexible cleaning member, the guide rollers 400 can also tension the flexible cleaning member, thereby ensuring that the flexible cleaning member has a certain tension, making it less likely for the flexible cleaning member to be entangled during the process of retraction and release, and ensuring the reliability of the cleaning equipment operation during the automated cleaning process.

[0030] In some specific embodiments of the present invention, the container for holding the cleaning liquid can be as follows: Figure 1The barrel 370 shown in the figure is mounted on the frame 100 through a bracket; it is understood that the container for the cleaning liquid can also be an external container. In order to spray the cleaning liquid from the barrel 370 onto the dust-free cloth, a liquid injection hole connecting the cavity is provided on the contoured cleaning head 310, and the cleaning liquid is sprayed onto the flexible cleaning member through the liquid injection hole. In order to spray the cleaning liquid evenly on the flexible cleaning member, a plurality of liquid injection holes are provided on the contoured cleaning head 310, and the plurality of holes are arranged along the length direction of the contoured cleaning head 310. In this embodiment, the cleaning liquid is specifically alcohol, and alcohol can effectively remove fingerprints and other dirt on the surface of the curved screen. For the curved screen of the mobile phone in this embodiment, the spray amount of alcohol is controlled to 0-5 ml / s, which can effectively remove dirt on the surface of the curved screen and is not easy to remain. It is understood that the corresponding alcohol spray amount can be set according to the size of the screen and the work efficiency.

[0031] In some specific embodiments of the present invention, the contoured cleaning head 310 is made of a flexible material. When the contoured cleaning head 310 acts on the curved screen, it can not only reduce the scratches on the curved screen, but also further adapt to the shape of the curved screen through its own deformation, so that the flexible cleaning member is in full contact with the curved screen, thereby improving the cleaning effect. It is understandable that the contoured cleaning head 310 can be made of a flexible material as a whole, or the surface of the contoured cleaning head 310 can be made of a flexible material. The flexible material can be rubber or elastomeric.

[0032] In some specific embodiments of the present invention, the second driving device 350 is installed on the frame 100, and the second driving device 350 can drive the contour cleaning head 310 to approach or move away from the curved screen.

[0033] The second driving device 350 drives the contour cleaning head 310 to move in a direction close to the curved screen until the contour cleaning head 310 makes the flexible cleaning member contact the part of the curved screen to be cleaned, thereby achieving a close fit between the flexible cleaning member and the curved screen, which helps to improve the cleaning effect. After cleaning, the second driving device 350 drives the contour cleaning head 310 to move in a direction away from the curved screen to prevent the contour cleaning head 310 from obstructing the operation of the curved screen. The second driving device 350 can be a cylinder, a screw motor, etc. The second driving device 350 can directly move the contour cleaning head 310, or a second driving device 350 can be set between the second driving device 350 and the contour cleaning head 310. Figure 2 The transmission mechanism includes a guide rail 330, a slider 340, a mounting plate 320 and a second driving device 350 which are respectively fixedly connected to both ends of the slider 340. The second driving device 350 drives the slider 340 to move up and down along the guide rail 330, thereby driving the contour cleaning head 310 to move up and down.

[0034] In combination with the above embodiments, a cleaning method of a cleaning device according to an embodiment of the present invention includes the following steps:

[0035] Step (A), the receiving motor 230 drives the receiving assembly 220 to receive and release the dust-free cloth, and the dust-free cloth is replaced. After the clean dust-free cloth is replaced, the receiving motor 230 stops driving the receiving assembly 220 to rotate;

[0036] Step (B), the second driving device 350 drives the contour cleaning head 310 to move downward, so that the contour cleaning head 310 makes the flexible cleaning member contact the part to be cleaned of the curved screen;

[0037] Step (C), the first driving device 600 drives the frame to reciprocate as a whole, so that the flexible cleaning member and the curved screen move relative to each other. The first driving device 600 reciprocates once to complete the cleaning of the curved screen.

[0038] Step (D), replace the curved screen, repeat step (C), and clean the new curved screen;

[0039] Step (E), after repeating step (D) a certain number of times, repeat step (A).

[0040] Some embodiments of the present invention also disclose an automatic film laminating machine for laminating a curved screen, including the cleaning device of the above embodiments. By using the cleaning device, the curved screen can be cleaned, the film laminating quality can be improved, and the film laminating of the curved screen can be automated.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
