As described in conjunction with fig. 1 to 5, the embodiment of the present disclosure provides a method for manufacturing a roller 100, including the following steps:

s100, arranging the shaft core 110 of the roller 100 in a die cavity of a casting die, casting an elastic material into the die cavity, standing for forming, and demolding to obtain the elastic shaft core 110 coated with the elastic layer 120; wherein the die cavity is cylindrical.

In step S100, the elastic material includes silicone rubber or a microporous rubber sponge. The elastic layer 120 obtained by pouring the silicon rubber or the microporous rubber sponge has better elasticity and better friction buffering effect.

S200, coating a flexible material on the outer peripheral wall of the elastic shaft core 110 to obtain a flexible layer 130; the preparation of the roller 100 is completed.

In step S200, the flexible material is selected from materials having a decontamination ability and being used for cleaning. Alternatively, the flexible material comprises a knitted material or a flexible leather or the like.

In the manufacturing method of the roller 100 according to the embodiment of the present disclosure, the casting process is adopted to directly mold the elastic layer 120 on the shaft core 110, and the manufactured roller 100 has the advantages of good bonding strength between the elastic layer 120 and the shaft core 110, difficulty in separation and long service life. And the preparation method is simple and convenient to implement. As shown in fig. 1, a roller 100 obtained in the embodiment of the present disclosure includes a core 110, an elastic layer 120, and a flexible layer 130, where the elastic layer 120 is cast on the core 110, and the flexible layer 130 is coated on the elastic layer 120. In the practical application process, the elastic layer 120 and the shaft core 110 are ensured not to move relatively, and the use effect is ensured. Particularly, in the case of a miniaturized roller 100, for example, a roller 100 having a diameter of the core 110 less than or equal to 6mm, due to the limitation of the size, it is difficult to design the miniaturized roller 100 by covering the surface of the core 110 with the elastic layer 120 and ensuring the bonding strength between the elastic layer 120 and the core 110. In the embodiment of the disclosure, the pouring process is combined into the roller 100, so that the problem of the bonding strength between the shaft core 110 and the elastic layer 120 of the miniaturized roller 100 is effectively and skillfully solved, the elastic layer 120 and the shaft core 110 are ensured not to move relatively, the use effect is ensured, the service life of the roller 100 is prolonged, and the replacement frequency is reduced.

In some embodiments, in step S100, the elastomeric casting fluid is doped with a porogen. The elastic layer obtained by demolding after molding has a porous structure in the form of pores scattered in the elastic layer 120.

Optionally, the shortest distance d2 between the axes 110 of the two rollers 100 is greater than the maximum thickness of the type of end device that is suitable. The roller mechanism is guaranteed to clamp the terminal equipment, meanwhile, smooth passing of the terminal equipment suitable for all general types is guaranteed, and friction cleaning is completed.

For example, when the type of the applicable terminal device is a mobile phone, d1 is smaller than the minimum thickness of a general mobile phone, and d2 is larger than the maximum thickness of the general mobile phone.

In some embodiments, the spacing between the two rollers 100 in each pair of rollers 100 is variable. Alternatively, the roller 100 can be moved in a first direction perpendicular to the axial direction thereof.

As shown in fig. 6 to 10, an embodiment of the present disclosure provides a roller assembly including a first base 151, a second base 152, a first elastic member 153, a second elastic member 154, and a roller 100. A first moving structure 1510 is disposed on the first base 151, and the first moving structure 1510 can move in a first direction (as indicated by the double-headed arrow in fig. 6); a second moving structure 1520 is disposed on the second base 152, and the second moving structure 1520 can move in the first direction; the first elastic member 153 is disposed on the first base 151 along the first direction, and one end thereof is connected to the first base 151 and the other end thereof is connected to the first moving structure 1510; the second elastic member 154 is disposed on the second base 152 along the first direction, and one end thereof is connected to the second base 152 and the other end thereof is connected to the second moving structure 1520; the first shaft end of the roller 100 is rotatably disposed on the first moving structure 1510, and the second shaft end is rotatably disposed on the second moving structure 1520.

In the roller assembly of the embodiment of the present disclosure, the first base 151 and the second base 152 are fixedly disposed, and the first moving mechanism and the second moving mechanism 1520 are movable in the first direction, so that the roller 100 can be reciprocally moved in the first direction. The first and second

elastic members

153 and 154 restrict the roller 100 to an initial position, as the roller 100 is in the position shown in fig. 6 and 7, without an external force. When an external force is applied to the roller 100, the first elastic member 153 and the second elastic member 154 are simultaneously compressed and deformed, and the roller 100 can move in a first direction (a position in a pressed state shown in fig. 8); and after the external force is removed, the roller 100 returns to the original position by the restoring force of the first elastic member 153 and the second elastic member 154. That is, the roller 100 assembly 10 of the embodiment of the present disclosure can buffer an external force applied thereto, and has a self-resetting function.

Therefore, in the roll mechanism 10 (as shown in fig. 9 and 10) configured by using the roll assembly, the distance between the two rolls 100 arranged in pairs can be changed, so that the roll mechanism can be adapted to the terminal equipment 50 with different thicknesses.

Optionally, the first moving structure 1510 and the second moving structure 1520 are both bracket structures and are slidably disposed on the corresponding first base 151 and the corresponding second base 152. That is, a slide 155 in a first direction is provided on each of the first and

second bases

151 and 152, so that the first and second moving

structures

1510 and 1520 are slidably disposed. As shown in fig. 7 and 8 in conjunction, the first end 1551 of the runway 155 defines an initial position of the roller 100; when the first elastic member 153 and the second elastic member 154 are compressed to move toward the second end 1552 of the slide path 155, the roller 100 moves toward the second end 1552 of the slide path 155 in the first direction, away from the initial position.

In the embodiment of the present disclosure, two shaft ends of the roller 100 are respectively rotatably disposed on the first moving structure 1510 and the second moving structure 1520, and the connection manner is not limited, and the roller can be rotated. Alternatively, two shaft ends of the roller 100 are rotatably disposed through bearings, respectively, that is, the first moving structure 1510 and the second moving structure 1520 are bearings, respectively, or a fixing portion of the bearing is fixedly disposed on the first moving structure 1510 or the second moving structure 1520, and the rotating portion is connected to the shaft ends of the roller 100.

In some embodiments, the roller assembly further comprises a drive motor 156 disposed on either the first 1510 or second 1520 moving structure; an output shaft of the drive motor 156 is connected to a shaft end (first shaft end or second shaft end) of the roller 100 on the corresponding side. That is, the driving motor 156 is fixedly disposed on the first moving structure 1510 or the second moving structure 1520, and can move synchronously in the first direction along with the moving structure, and at the same time, can drive the roller 100 to rotate. Alternatively, the driving motor 156 is disposed on the second moving structure 1520, and an output end thereof is connected to the second shaft end of the roller 100 on the corresponding side.

In some embodiments, the first elastic member 153 and the second elastic member 154 are both springs.

One end of the second spring is connected to the second base 152, and the other end is connected to the second moving structure 1520.

The embodiment of the present disclosure provides a terminal device cleaning machine, which is shown in fig. 11 to 14 and includes: the roll mechanism 10 and the bracket mechanism 20 of any one of the foregoing embodiments. A carriage mechanism including a carriage 21, the carriage 21 being capable of reciprocating on a movement path of the terminal device 50 and providing a support for the terminal device; the bracket mechanism enables the roller in a rotating state to rub on the surface of the terminal device 50 by controlling the movement speed of the terminal device, so that the cleaning effect of manually pressing and wiping is realized.

In the embodiment of the present disclosure, the roll-to-roll mechanism 10 realizes that the terminal device 50 can automatically enter the cleaning machine, complete cleaning when passing through the two rollers 100 of the roll-to-roll mechanism 10, and automatically push out after cleaning is completed, thereby facilitating the use of a user. Moreover, when cleaning/disinfecting work is carried out, the roller 100 generates friction on the surface of the terminal equipment 50, the friction is similar to the friction of manual pressing and wiping, especially the friction of finger pressing and wiping, in a double-roller mechanism, the distance between two rollers (the first roller 101 and the second roller 102) which are arranged in pairs is adjustable, the double-roller mechanism is more suitable for the terminal equipment 50 with different thicknesses, and the double-roller mechanism is matched with a soft layer on the surface of the roller 100, so that the friction can be buffered, and the effect even superior to the effect of manual cleaning of the surface of the terminal equipment is achieved.

The terminal equipment cleaning machine disclosed by the embodiment of the disclosure adopts the traditional method of spraying the sterilization liquid and the bacteriostatic liquid for sterilization, and the sterilization/bacteriostatic effect is stable and guaranteed. But also can make the terminal equipment clean, disinfect, antibacterial convenient, normalized, make the terminal equipment clean become the essential part in people's life, develop better health habit.

The terminal device cleaning machine of the embodiment of the present disclosure can rapidly complete the cleaning of the terminal device 50 by setting the rotation speed (linear speed) of the roller 100 of the counter roller mechanism 10 and the moving speed of the bracket 21, and can complete the whole cleaning process within 10 seconds to 20 seconds. The terminal equipment cleaning machine can be placed around a hand washing sink and the like for use, and a user can also place terminal equipment (such as a mobile phone) into the equipment before washing hands, the equipment automatically sucks the terminal equipment for 10-20 seconds in the hand washing process, the equipment finishes washing and sterilizing the mobile phone, and the mobile phone automatically pops up. And the user takes the mobile phone away after washing hands. The hand cleaning and the mobile phone cleaning are carried out synchronously. The cross infection caused by inconsistent cleaning of the hands and the mobile phone is avoided, and the use of the mobile phone by people is not delayed by utilizing the fragmentary time that the user does not use the mobile phone when washing the hands.

Alternatively, the linear velocity of the rollers in the roll-to-roll mechanism 10 is greater than the moving velocity of the carriage 21.

In some embodiments, in a roller mechanism, the distance between two rollers (the first roller 101 and the second roller 102) arranged in pairs is adjustable, so that the first end of the motion path of the terminal equipment is positioned at the first side of the roller mechanism, and the second end is positioned at the second side of the roller mechanism. So that the carrier 21 of the carrier mechanism 20 can pass through the washing passage with a variable distance between the two rollers 100 without causing excessive pressing friction to the rollers. When the terminal device 50 is placed in the bracket 21, the user does not need to press the terminal device 50 into the cleaning channel, and the user experience is improved.

In the terminal equipment cleaning machine of the embodiment of the present disclosure, a liquid supply mechanism 30 having a liquid supply tip 31 for supplying a cleaning liquid onto the roller 100 is further included. The liquid supply mechanism may be a liquid supply mechanism of an existing terminal equipment cleaning machine, or may be other liquid supply mechanisms capable of supplying cleaning liquid to the roller 100, and is not limited.

The liquid supply mechanism can be a liquid scraping mechanism of an existing terminal equipment cleaning machine, or other liquid scraping mechanisms capable of scraping residual cleaning liquid on the roller 100, and is not limited.

Alternatively, as shown in fig. 13 and 14, a liquid scraping mechanism 40 includes two scraping blades 41, a restoring structure 43 and a limiting structure 42, the scraping blades 41 have soft end portions 411, the two scraping blades 41 are oppositely arranged in a manner that the soft end portions 411 are opposite, and each scraping blade 41 is rotatably arranged. The limiting structure 42 is arranged on the first side surface side of the scraping blade 41 to limit the rotation of the scraping blade 41 to the first side surface side; the reset structure 43 is disposed on the scraping blade 41, and the reset structure 43 can keep the scraping blade 41 in a horizontal state or abut against the limiting structure 42. In the liquid scraping mechanism 40, the scraping blade 41 can freely rotate towards the second side surface, the rotation of the scraping blade on the first side surface side is limited by the limiting structure 42, the scraping blade rotates to the position which is abutted against the limiting structure 42 at most, and under the condition of not being interfered by external force, the resetting structure 43 is arranged to enable the scraping blade 41 to be kept in a horizontal state or abutted against the limiting structure 42; when receiving a force toward the second side surface, the blade 41 is freely rotatable toward the second side surface.

In some embodiments, as shown in fig. 11, when the carriage 21 is located at the first end of the movement path of the terminal device 50, the support surface of the carriage 21 overlaps the ends of the two blades 41. That is, when the terminal equipment cleaning machine is in a standby state or a shutdown state, the inlet and outlet of the cleaning machine form a relatively closed structure, so that foreign matters such as dust can be effectively prevented from falling into the cleaning machine, the environment is prevented from causing the roller 100 to be polluted, and the cleaning effect is reduced.

In some embodiments, as shown in FIG. 12, the end station cleaning machine further includes a cleaning bin 62 disposed in the end station path of motion on the second side of the counter roller mechanism to define the cleaning path of the end station in spaced relation. That is, the terminal device 50 moves into the cleaning bin under the driving of the bracket 21 after passing through the roller mechanism 10; when the carriage 21 reaches the entry end position (i.e., the second end of the movement path), the end setting 50 completes the cleaning completely by the roller mechanism 10. At this time, the cleaning bin 62 is matched with the bracket 21, so that the terminal equipment is kept on the moving path, and the phenomenon that the terminal equipment is inclined or even toppled to be blocked when being pushed out is avoided. The structure of the cleaning bin is not limited, as shown in fig. 12, the cleaning bin arranged along the moving direction of the bracket 21 may be an integral box body, and moving guide grooves at two ends of the bracket 21 are formed on two side walls of the cleaning bin in the direction parallel to the axial direction of the roller.
