[0043] An embodiment of the present application provides a roller surface cleaning device, which relates to the field of battery production technology and is mainly used to clean the roller surface to be cleaned on a production line.

[0044] like Figure 1 and Figure 2 As shown, the roller surface cleaning device 100 provided in this embodiment includes: a scraper 110 , a wiping member 120 , a vacuum cleaning mechanism 130 and a rotating member 140 .

[0045] The vacuum cleaning mechanism 130 includes a housing 131, a first air knife 132, and a second air knife 133. The housing 131 defines a suction channel 1311 and has an opening 1312 communicating with the suction channel 1311. The first air knife 132 and the second air knife 133 are respectively connected to the inner sidewall of the housing 131 and are respectively housed within the suction channel 1311. The rotating member 140 is rotatable about its rotation axis 141. The scraper 110, the wiper 120, and the vacuum cleaning mechanism 130 are respectively connected to the outer periphery of the rotating member 140.

[0046] It should be noted that the scraper 110 and the wiper 120 can be connected to the outer periphery of the rotating member 140 by means of embedded connection, screw connection, clamping connection, bonding, etc. Here, the vacuum cleaning mechanism 130 connected to the outer periphery of the rotating member 140 means that the housing 131 is connected to the outer periphery of the rotating member 140, and can be directly connected to the rotating member 140 or indirectly connected to the rotating member 140 through other structures, and no specific limitation is given here.

[0047] like Figure 1 As shown, for example, the vacuum cleaning mechanism 130 is located between the scraper 110 and the wiper 120. Of course, the scraper 110 may also be located between the vacuum cleaning mechanism 130 and the wiper 120, or the wiper 120 may be located between the scraper 110 and the vacuum cleaning mechanism 130. The positional relationship between the three is not specifically limited herein.

[0048] It should be noted that during the cleaning process, the scraper 110 is used to contact the roller surface 200 to be cleaned, thereby scraping away most of the oil and foreign matter on the roller surface 200. The vacuum cleaning mechanism 130 is used to spray high-speed airflow onto the roller surface 200 to be cleaned (the first air knife 132 and the second air knife 133 each have an airflow injection hole), and vacuum-absorb the oil droplets and foreign matter released by the injected airflow (the suction channel 1311 is connected to the suction element). The wiper 120 is used to contact the roller surface 200 to be cleaned, thereby wiping away any remaining oil droplets and foreign matter.

[0049] It should be noted that the high-speed airflow of the vacuum cleaning mechanism 130 is ejected by connecting to a ready-made public utility compressed air tank on the production line, for example, indirectly connected to the air tank through an air pipe, or directly connected to the air tank, which will not be elaborated here.

[0050] Exemplarily, the wiper 120 may be a scouring pad, a dust-free cloth, a sponge, etc., and the scraper 110 may be a polyurethane scraper, a rubber scraper, a silicone scraper, a wooden scraper, etc., and no specific limitation is made to the types of the wiper 120 and the scraper 110.

[0051] It will be appreciated that in the roller surface cleaning device 100 provided in this embodiment, since the scraper 110, the wiping member 120, and the vacuum cleaning mechanism 130 are respectively connected to the outer periphery of the rotating member 140, the rotating member 140 is capable of rotating about its rotation axis 141. The vacuum cleaning mechanism 130 includes a housing 131, a first air knife 132, and a second air knife 133. The housing 131 defines an adsorption channel 1311 and has an opening 1312 communicating with the adsorption channel 1311. The first air knife 132 and the second air knife 133 are respectively connected to the inner side wall of the housing 131, and the first air knife 132 and the second air knife 133 are respectively accommodated within the adsorption channel 1311. The scraper 110 is used to contact the roller surface 200 and scrape off most of the oil and foreign matter on the roller surface 200. The vacuum cleaning mechanism 130 uses the first air knife 132 and the second air knife 133 to spray high-speed airflow to disperse the surface oil layer and remaining foreign matter on the roller surface 200. The blown-off oil droplets and foreign matter are then vacuum-absorbed through the adsorption channel 1311. The wiper 120 is used to contact the roller surface 200 and wipe off any remaining oil droplets and foreign matter on the roller surface 200. In this way, by rotating the rotating member 140, different cleaning methods can be selected to clean the roller surface 200. The combination of the three cleaning methods can better clean the roller surface 200, achieving high cleaning efficiency and a good cleaning effect.

[0052] like Figure 1 and Figure 2 As shown, in one embodiment, the first air knife 132 is arranged on one side close to the opening 1312 along the direction of the rotation axis 141 of the rotating member 140, and the second air knife 133 is arranged on the other side close to the opening 1312 along the direction of the rotation axis 141 of the rotating member 140. The vacuum cleaning mechanism 130 also includes a plurality of contact rollers 134, and the plurality of contact rollers 134 are respectively rotatably connected to the inner side walls of the shell 131, and the plurality of contact rollers 134 are spaced apart along the edge of the opening 1312, and each contact roller 134 is protruding from the shell 131.

[0053] For example, the number of the contact rollers 134 may be two, three, four, five, six, seven, etc., and is not specifically limited here. The contact rollers 134 may be made of elastic materials such as polyurethane, silicone, rubber, sponge, etc., and is not specifically limited here.

[0054] It should be noted that the vacuum cleaning mechanism 130 is equipped with a contact roller 134 to limit rigid contact between the housing 131 and the roller surface 200 to be cleaned, preventing the roller surface 200 from being impacted by the housing 131. This allows the vacuum cleaning mechanism 130 to perform contact vacuum cleaning on the roller surface 200, thereby reducing airflow leakage and achieving a better cleaning effect. When designing the contact roller 134, the inventors attempted to place the contact roller 134 in the middle of the housing 131. However, this placement of the contact roller 134 would occupy space in the suction channel 1311, thereby disrupting the suction airflow and hindering vacuum suction.

[0055] In this embodiment, since the size of the contact roller 134 is reduced, multiple contact rollers 134 are provided, and the multiple contact rollers 134 are spaced apart along the edge of the opening 1312, and each contact roller 134 is provided to protrude from the shell 131. This can avoid the rigid contact between the shell 131 and the roller surface 200 to be cleaned, and will not affect the suction airflow in the adsorption channel 1311, thereby improving the cleaning effect.

[0056] It should be noted that if the height of the contact roller 134 protruding from the housing 131 is too great, it will affect the sealing environment of the suction airflow, thereby reducing the cleaning effect. If the height of the contact roller 134 protruding from the housing 131 is too small, the risk of rigid contact between the housing 131 and the roller surface 200 increases. However, setting the height of the contact roller 134 protruding from the housing 131 within the range of 1 mm to 5 mm can improve this problem.

[0057] like Figure 2 As shown, further, the side of the shell 131 with the opening 1312 has a plurality of corner areas 1314 , and each corner area 1314 is provided with a contact roller 134 .

[0058] For example, when there are four corner regions 1314 , the number of contact rollers 134 is also four. The number of corner regions 1314 and the number of contact rollers 134 are in a one-to-one correspondence, and no specific limitation is imposed on the number of the two.

[0059] In this embodiment, since each corner area 1314 is provided with a contact roller 134, that is, multiple contact rollers 134 are provided one by one on multiple corner areas 1314, this can maximize the improvement of the disturbance of the suction airflow by the contact roller 134, and further improve the cleaning effect.

[0060] like Figure 2As shown, in one embodiment, the vacuum cleaning mechanism 130 further includes a suction piece, and a docking port 1313 connected to the adsorption channel 1311 is provided on the side of the housing 131 away from the opening 1312, and the suction piece is connected to the docking port 1313 to generate a suction airflow. For example, the suction piece can be a vacuum pump, a blower, a fan, or other device that can generate a suction airflow in the adsorption channel 1311, and no specific limitation is made here. A plurality of docking ports 1313 can be provided, and each docking port 1313 is docked with the suction piece through a hose. In addition, the suction piece can be connected to the rotating member 140 by means of embedded connection, screw connection, clamping, bonding, etc. Of course, the suction piece can also be not provided on the rotating member 140, but connected to the docking port 1313 through a hose, and no specific limitation is made here.

[0061] In this embodiment, the provision of the docking port 1313 enables communication between the suction channel 1311 and the suction member, enabling the suction channel 1311 to vacuum-absorb oil droplets and foreign matter released from the roller surface 200 to be cleaned. Exemplarily, the vacuum cleaning mechanism 130 further includes a filter tank having a receiving chamber, which is connected between the docking port 1313 and the suction member to accommodate the oil droplets and foreign matter sucked by the suction member through the receiving chamber.

[0062] like Figure 3 As shown, in one embodiment, the roller surface cleaning device 100 further includes a fixed bracket 150, a first driving mechanism 160 and a second driving mechanism 170, the rotating member 140 is rotatably disposed on the fixed bracket 150, the first driving mechanism 160 is disposed on the fixed bracket 150 and is connected to the rotating member 140, for driving the rotating member 140 to rotate around its rotation axis 141, and the second driving mechanism 170 is connected to the fixed bracket 150, for driving the first driving mechanism 160, the fixed bracket 150 and the rotating member 140 to move synchronously.

[0063] For example, the first driving mechanism 160 may be a device such as a rotary motor or a driving motor that can output torque to drive the rotating member 140 to rotate, and no specific limitation is made here.

[0064] In this embodiment, since the roller surface cleaning device 100 further includes a fixed bracket 150, a first drive mechanism 160, and a second drive mechanism 170, the rotating member 140 is rotatably mounted on the fixed bracket 150, the first drive mechanism 160 is mounted on the fixed bracket 150 and connected to the rotating member 140, and the second drive mechanism 170 is connected to the fixed bracket 150. Thus, the first drive mechanism 160 can drive the rotating member 140 to rotate about its rotation axis 141, thereby enabling any one of the scraper 110, the wiper 120, and the vacuum cleaning mechanism 130 to be selected to clean the roller surface 200 to be cleaned. The second drive mechanism 170 can drive the first drive mechanism 160, the fixed bracket 150, and the rotating member 140 to move synchronously, thereby adjusting the position of the rotating member 140 relative to the roller surface 200.

[0065] like Figure 3 As shown, further, the second drive mechanism 170 includes a first drive assembly 171 and a second drive assembly 172. The first drive assembly 171 is connected to the fixed bracket 150 and is used to drive the first drive mechanism 160, the fixed bracket 150, and the rotating member 140 to move synchronously in a direction close to or away from the roller surface 200 to be cleaned. The second drive assembly 172 is connected to the first drive assembly 171 and is used to drive the first drive assembly 171, the first drive mechanism 160, the fixed bracket 150, and the rotating member 140 to move synchronously in the direction of the rotation axis 141 of the rotating member 140.

[0066] In this embodiment, the second drive mechanism 170 includes a first drive assembly 171 and a second drive assembly 172. The first drive assembly 171 is connected to the fixed bracket 150, and the second drive assembly 172 is connected to the first drive assembly 171. Thus, the first drive assembly 171 can drive the first drive mechanism 160, the fixed bracket 150, and the rotating member 140 to move synchronously toward or away from the roller surface 200 to be cleaned, that is, to move vertically up and down relative to the roller surface 200, so that the scraper 110, the wiper 120, and the vacuum cleaning mechanism 130 on the rotating member 140 can clean the selected roller surface 200. The second drive assembly 172 can drive the first drive assembly 171, the first drive mechanism 160, the fixed bracket 150, and the rotating member 140 to move synchronously along the rotation axis 141 of the rotating member 140, so that the rotating member 140 can move between different roller surfaces 200 to be cleaned, thereby cleaning multiple roller surfaces 200 to be cleaned.

[0067] like Figure 1 and Figure 3As shown, further, the fixed bracket 150 includes two bracket bodies 151, the rotating member 140 is located between the two bracket bodies 151, the first driving mechanism 160 is arranged on one of the bracket bodies 151 and is connected to one end of the rotating member 140, and the end of the rotating member 140 away from the first driving mechanism 160 is rotatably connected to the other bracket body 151.

[0068] In this embodiment, two bracket bodies 151 are provided, wherein one bracket body 151 is used to carry the rotating member 140 to facilitate the rotational connection between the rotating member 140 and the fixed bracket 150, and the other bracket body 151 is used to carry the first driving mechanism 160 to facilitate the first driving mechanism 160 to drive the rotating member 140 to rotate.

[0069] like Figure 1 and Figure 3 As shown, further, the first driving assembly 171 includes two first driving members 1711 , and the rotating member 140 is located between the two first driving members 1711 .

[0070] For example, the first driving member 1711 may be a device capable of outputting linear motion, such as a cylinder or a linear motor mold, and no specific limitation is made here.

[0071] In this embodiment, two first driving members 1711 are provided and the rotating member 140 is arranged between the two first driving members 1711. In this way, the two first driving members 1711 can jointly drive the first driving mechanism 160, the fixed bracket 150 and the rotating member 140 to move synchronously in the direction of approaching or moving away from the roller surface 200 to be cleaned, so that the rotating member 140 has higher movement stability.

[0072] like Figure 3 As shown, further, the second drive assembly 172 includes a rack 1721, two gears and two second drive members 1722. The length direction of the rack 1721 is parallel to the direction of the rotation axis 141 of the rotating member 140. The two gears are respectively engaged with the rack 1721. The rotating member 140 is located between the two second drive members 1722. Each second drive member 1722 is connected between the first drive assembly 171 and a gear to drive the gear connected thereto to rotate.

[0073] For example, the second driving member 1722 may be a rotating motor, a driving motor, or other device that can output torque to drive the gear to rotate, and no specific limitation is given here.

[0074] In this embodiment, by setting up two second driving members 1722 and arranging the rotating member 140 between the two second driving members 1722, the two second driving members 1722 can jointly drive the first driving assembly 171, the first driving mechanism 160, the fixed bracket 150 and the rotating member 140 to move synchronously along the direction of the rotation axis 141 of the rotating member 140 through the engagement of two gears with the rack 1721, so that the rotating member 140 has higher movement stability.

[0075] Of course, for the above embodiment, chains and sprockets can also be used instead of gears and racks 1721 to achieve the same linear displacement effect. No specific restrictions are made on the structure of the second drive assembly 172 here.
