[0043] In one embodiment, referring to Figure 1 and Figure 2 The cleaning device comprises:

[0044] A carrying mechanism 1;

[0045] The cleaning mechanism 2 comprises a cleaning roller 21, the cleaning roller 21 is rotationally connected to the bearing mechanism 1, and the cleaning roller 21 is provided with an adhesive part 211, and the cleaning roller 21 is used to contact the to-be-cleaned roller through the adhesive part 211.

[0046] When the to-be-cleaned roller rotates, the cleaning roller 21 can be driven to rotate to clean the surface of the to-be-cleaned roller through the adhesive part 211.

[0047] In this embodiment, the bearing mechanism 1 can comprise a base, the cleaning mechanism 2 is connected to the base, and the cleaning roller 21 can rotate relative to the base.

[0048] When the adhesive part 211 provided on the cleaning roller 21 contacts the to-be-cleaned roller, the cleaning roller 21 and the to-be-cleaned roller can be adhered together through the adhesive part 211, so as to drive the cleaning roller 21 to rotate when the to-be-cleaned roller rotates; it is worth noting that the adhesion generated by the adhesive part 211 will not adhere the fixed positions of the cleaning roller 21 and the to-be-cleaned roller together all the time, the cleaning roller 21 and the to-be-cleaned roller are adhered together at the first time before the to-be-cleaned roller rotates; after the to-be-cleaned roller rotates to the second time, the driving force of the to-be-cleaned roller rotating can overcome the adhesion generated by the adhesive part 211, so that the positions of the cleaning roller 21 and the to-be-cleaned roller adhered at the first time are separated, and then the cleaning roller 21 and the to-be-cleaned roller are adhered together at the second time, that is, in the process of the to-be-cleaned roller rotating, different positions of the cleaning roller 21 and different positions of the to-be-cleaned roller can be kept adhered to realize the cleaning of different positions of the to-be-cleaned roller in turn, and ensure the comprehensiveness of the cleaning device in cleaning the to-be-cleaned roller.

[0049] In one embodiment, the to-be-cleaned roller is used to support a film substrate in an evaporation film plating process, for example, the film substrate is a PET film, and a large amount of powder is generated in the evaporation process, which is easy to float and adhere to the surface of the to-be-cleaned roller; in addition, when the PET film is broken, the evaporated metal particles can adhere to the to-be-cleaned roller through the broken position of the PET film, which affects the cleaning state of the surface of the to-be-cleaned roller.

[0050] In the cleaning device provided in the embodiment, the surface of the cleaning roller 21 is provided with the adhesive part 211, for example, a sticky tape is attached to the surface of the cleaning roller 21, and the tape can adhere to the powder and metal particles; when the to-be-cleaned roller rotates, the cleaning roller 21 can rotate with the to-be-cleaned roller, and the adhesive part 211 can clean the dust on the surface of the to-be-cleaned roller and the metal particles and other foreign matters adhered to the surface of the to-be-cleaned roller due to the breaking of the film substrate.

[0051] Through the timely cleaning of the surface of the to-be-cleaned roller by the cleaning roller 21, the cleanliness of the surface of the to-be-cleaned roller is improved, and the film quality during evaporation coating is ensured. In addition, when the film substrate is broken during conveying, the surface of the roller can be kept flat through the timely cleaning of the surface of the to-be-cleaned roller by the cleaning roller 21, and the effective support and conveying of the to-be-cleaned roller on the subsequent film substrate are ensured.

[0052] The cleaning device provided by the embodiment of the application comprises a bearing mechanism 1, and a cleaning mechanism 2. The cleaning mechanism 2 comprises a cleaning roller 21, the cleaning roller 21 is rotationally connected to the bearing mechanism 1, the cleaning roller 21 is provided with an adhesive part 211, and the cleaning roller 21 is used to contact the to-be-cleaned roller through the adhesive part 211. The to-be-cleaned roller can drive the cleaning roller 21 to rotate under the condition that the to-be-cleaned roller rotates, so as to clean the surface of the to-be-cleaned roller through the adhesive part 211, and the cleanliness of the surface of the to-be-cleaned roller is ensured.

[0053] In one embodiment, referring to Figure 1 , the bearing mechanism 1 comprises a connecting structure 11, the connecting structure 11 is provided with a support rod 111, and the cleaning roller 21 is rotationally connected to the support rod 111.

[0054] In this embodiment, the cleaning roller 21 can be sleeved on the support rod 111 and can rotate relative to the support rod 111. The cleaning roller 21 and the support rod 111 can have a certain damping, and the driving force of the to-be-cleaned roller can overcome the damping. On the one hand, the cleaning roller 21 can be prevented from shaking randomly on the support rod 111, and on the other hand, the cleaning roller 21 can be driven to rotate when the to-be-cleaned roller rotates.

[0055] In one embodiment, the bearing mechanism 1 can comprise a base, the connecting structure 11 is directly connected to the base, and the cleaning roller 21 can be kept adhered to the to-be-cleaned roller through the adhesion generated by the adhesive part 211, so that the efficiency of the cleaning device in cleaning the to-be-cleaned roller is improved.

[0056] In one embodiment, referring to Figure 1 , the support rod 111 is provided with a bearing 112, and the cleaning roller 21 is connected to the support rod 111 through the bearing 112, so that the flexibility of the rotation of the cleaning roller 21 relative to the support rod 111 is ensured.

[0063] In this embodiment, when the shovel structure 22 approaches the surface of the roller to be cleaned and cleans the surface of the roller to be cleaned, the cleaning effect of the surface of the roller to be cleaned can be improved. For example, when the cleaning roller 21 cannot clean the impurities that are difficult to remove from the surface of the roller to be cleaned by adhesion, the shovel structure 22 approaches the impurities that are difficult to remove from the surface of the roller to be cleaned and is in contact with them during the rotation of the roller to be cleaned, thereby scraping the impurities from the surface of the roller to be cleaned. When the surface of the roller to be cleaned does not need to be cleaned by the shovel structure 22, the shovel structure 22 can move away from the roller to be cleaned to avoid scratching the roller to be cleaned by the shovel structure 22.

[0064] In one embodiment, referring to Figure 1 and Figure 2The shovel structure 22 comprises a back plate 221, a pressing plate 222 and a shovel 223.

[0065] In this embodiment, the head part of the shovel 223 can be used to scrape the impurities from the to-be-cleaned roller, improving the cleaning effect of the surface of the to-be-cleaned roller. The pressing plate 222 is used to press the shovel 223 flat on the back plate 221, so as to ensure the rigidity and straightness of the shovel 223 and maintain the stability of the cleaning effect of the shovel 223.

[0066] In some embodiments, the shovel 223 can be a metal shovel, so as to ensure the cleaning effect of the shovel 223. Alternatively, the shovel 223 can be a non-metal shovel, so as to avoid hard contact between the shovel and the surface of the to-be-cleaned roller.

[0067] In one embodiment, the shovel structure 22 comprises the shovel 223, which can be directly connected to the bearing mechanism 1, so as to simplify the structure of the cleaning device.

In this way, the cleaning effect of the shovel 223 on the surface of the to-be-cleaned roller 101 is ensured, and the integrity of the to-be-cleaned roller 101 is ensured.

[0070] In one embodiment, referring to Figure 1 and Figure 2 , the bearing mechanism 1 comprises a base 12 and a driving structure 13. The cleaning mechanism 2 is connected to the base 12 through the driving structure 13. The driving structure 13 is used to drive the cleaning mechanism 2 to approach or move away from the to-be-cleaned roller.

[0071] In this embodiment, the cleaning roller 21 can be connected to the base 12 through the driving structure 13, so as to drive the cleaning roller 21 to approach or move away from the to-be-cleaned roller through the driving structure 13. Alternatively, the shovel structure 22 can be connected to the base 12 through the driving structure 13, so as to drive the shovel structure 22 to approach or move away from the to-be-cleaned roller through the driving structure 13. Alternatively, the cleaning roller 21 and the shovel structure 22 can be connected to the base 12 through the driving structure 13, so as to drive the cleaning roller 21 and the shovel structure 22 to approach or move away from the to-be-cleaned roller through the driving structure 13, improving the activity efficiency of the cleaning mechanism 2.

[0072] In one embodiment, referring to Figure 1 and Figure 2 the driving structure 13 comprises a first driving unit 131, and the connecting structure 11 is connected to the base 12 through the first driving unit 131.

[0073] The first driving unit 131 is used to drive the connecting structure 11 to move, so that the cleaning roller 21 approaches or moves away from the to-be-cleaned roller.

[0074] In this embodiment, the first driving unit 131 can include at least one of a pneumatic cylinder unit and a motor unit, and the first driving unit 131 is used to drive the connecting structure 11 to move, so that the cleaning roller 21 presses or lifts up the to-be-cleaned roller under the driving of the connecting structure 11, and the cleaning roller 21 and the to-be-cleaned roller are in contact or separated, which facilitates flexible control of the cleaning roller 21 on the to-be-cleaned roller.
