[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] It should be understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] Please see Figures 1 to 5This utility model provides a roller placement device 100 for placing rollers 200, including a housing 10, an upper plate fixing assembly 20, and a lower plate fixing assembly 30. The housing 10 has a receiving cavity 11 and an upper plate opening 13, which communicates with the receiving cavity 11 and is located above the receiving cavity 11. The upper plate fixing assembly 20 is disposed on the housing 10 and covers at least a portion of the upper plate opening 13. The upper plate fixing assembly 20 includes a plurality of fixing upper plates 21, which are used to limit one end of the roller 200. The lower plate fixing assembly 30 is disposed at the bottom of the receiving cavity 11 and has a first limiting groove 31, which is used to receive and limit the end of the roller 200 away from the fixing upper plate 21.

[0045] In this embodiment of the utility model, the upper plate fixing component 20 limits one end of the roller 200, and the lower plate fixing component 30's first limiting groove 31 limits the other end of the roller 200, so that the roller 200 can be limited within the accommodating cavity 11, avoiding deformation of the roller 200 caused by stacking and pressure, ensuring the accuracy of the roller 200, and thus reducing the probability of problems such as shaking and over-etching of the battery during the cleaning process.

[0046] Understandably, the two ends of the roller 200 along the rotation axis are respectively limited to the upper plate fixing component 20 and the lower plate fixing component 30, so as to ensure the accuracy of the roller part of the roller 200 and reduce the difficulty of limiting the roller 200.

[0047] It is worth noting that the upper plate fixing assembly 20 and the lower plate fixing assembly 30 can be distributed vertically, horizontally, or at a certain angle. This application does not impose any specific limitations. In one embodiment, the upper plate fixing assembly 20 is located above the lower plate fixing assembly 30. This allows for better utilization of vertical space for storing the roller 200. It is understood that, taking the axial dimension of the roller 200 as its length, the roller 200 is typically quite long. Vertical placement of the roller 200 reduces the floor space required for its placement, thus making better use of vertical space.

[0048] Specifically, the accommodating cavity 11 is used to accommodate the roller 200, thereby reducing the probability of the roller 200 being bumped or hit, and reducing the probability of dust contacting the roller 200. The upper plate opening 13 not only facilitates the placement of the upper plate fixing assembly 20 on the housing 10, but also reduces the production cost of the housing 10. In addition, in the embodiment where the roller 200 passes through the upper plate fixing assembly 20, the upper plate opening 13 can also provide sufficient space for the roller 200, reducing the size requirements of the housing 10, thereby reducing production costs. It is understood that the housing 10 may also be provided with a loading opening, which communicates with the accommodating cavity 11. The roller placement device 100 may also include a cabinet door for covering the loading opening. In this way, it is convenient to put the roller 200 into the accommodating cavity 11 or remove the roller 200 from the accommodating cavity 11 through the loading opening.

[0049] Understandably, there are many ways to fix the upper plate 21 to limit one end of the roller 200. In one embodiment, the upper plate 21 can clamp one end of the roller 200. In another embodiment, the upper plate 21 can abut against a portion of the roller 200. For example, in one embodiment, the upper plate fixing assembly 20 and the lower plate fixing assembly 30 are distributed horizontally, so the upper plate 21 can abut against one end of the roller 200 to support and limit the roller 200. In another embodiment, the upper plate fixing assembly 20 and the lower plate fixing assembly 30 are distributed vertically, so the upper plate 21 can extend into a smaller diameter portion of the roller 200 to abut against a larger diameter portion of the roller 200, thereby limiting the roller 200. It is understandable that multiple fixed upper plates 21 may correspond to one roller 200, or the fixed upper plates 21 and rollers 200 may correspond one-to-one, or one fixed upper plate 21 may correspond to multiple rollers 200. As long as the fixed upper plate 21 can limit the rollers 200, this application does not impose specific restrictions.

[0050] The lower plate fixing assembly 30 is provided with a first limiting groove 31 to accommodate and limit the end of the roller 200 away from the fixing upper plate 21. It is understood that the shape of the first limiting groove 31 can match the shape of one end of the roller 200, and it can be conical, cylindrical, cuboid, etc., and this application does not impose any specific limitations.

[0051] It is worth noting that there are many ways in which the upper plate fixing component 20 is provided on the housing 10. It can be that the housing 10 has a receiving groove for the upper plate fixing component 20, or the upper plate fixing component 20 is plugged into the housing 10, or the upper plate fixing component 20 is connected to the housing 10 by bolts, pins, etc. This application does not specifically limit it.

[0052] There are many ways in which the lower plate fixing component 30 is located at the bottom of the receiving cavity 11. It can be that the lower plate fixing component 30 is integrally formed with the housing 10, or the lower plate fixing component 30 is placed at the bottom of the receiving cavity 11, or the lower plate fixing component 30 is connected to the housing 10 by bolts, pins or other connecting parts. This application does not impose any specific restrictions.

[0053] Please see Figure 3 , Figure 4 and Figure 9 In this embodiment of the present invention, the fixed upper plate 21 includes a second limiting groove 211 and a third limiting groove 213. The second limiting groove 211 and the third limiting groove 213 are respectively located on both sides of the fixed upper plate 21. Multiple fixed upper plates 21 are arranged in sequence. The second limiting groove 211 of one fixed upper plate 21 and the third limiting groove 213 of the adjacent fixed upper plate 21 form a roller 200 limiting groove 23. One end of the roller 200 passes through the roller 200 limiting groove 23 to limit one end of the roller 200.

[0054] Thus, a fixed upper plate 21 can be first placed on the box body 10, and the roller 200 can be placed on the second or third limiting groove on the fixed upper plate 21. Then, another fixed upper plate 21 can be placed on the box body 10, so that the two adjacent fixed upper plates 21 together form the roller 200 limiting groove 23, thereby limiting the roller 200. The two fixed upper plates 21 together limit the roller 200, making it convenient to pick up or place the roller 200.

[0055] It is understandable that one end of the roller 200 passes through the roller 200 limiting groove 23. It can be that the two fixed upper plates 21 jointly clamp one end of the roller 200, or the two fixed upper plates 21 jointly abut against part of the roller 200. This application does not make specific restrictions.

[0056] Understandably, the shape of the limiting groove 23 of the roller 200 can match the shape of one end of the roller 200.

[0057] For further details, please refer to Figures 6 to 9 The roller 200 is provided with a mating groove 201, and the fixed upper plate 21 also includes a limiting protrusion 215. The limiting protrusion 215 is provided in the groove wall of the limiting groove 23 of the roller 200 in the horizontal direction. The limiting protrusion 215 is used to cooperate with the mating groove 201 of the roller 200 to limit the upper end of the roller 200.

[0058] In this way, the limiting protrusion 215 and the mating groove 201 can stably limit the upper end of the roller 200, reduce the probability of the roller 200 shaking, and thus reduce the precision loss caused by the roller 200 bumping.

[0059] It is worth noting that the size of the limiting protrusion 215 can be smaller than the size of the groove wall of the limiting groove 23 of the roller 200, so that the groove wall of the limiting groove 23 of the roller 200 without the limiting protrusion 215 naturally forms a depression. This depression can cooperate with the position of the roller 200 without the mating groove 201. This not only provides a stable limit for the roller 200, but also guides the roller 200 into the second limiting groove 211 or the third limiting groove 213, so that the mating groove 201 of the roller 200 can be aligned and cooperate with the limiting protrusion 215 during the placement of the roller 200.

[0060] Please see Figure 1 , Figure 2 and Figure 7 In this embodiment of the present invention, the roller placement device 100 further includes two track assemblies 40, which are disposed on opposite sides of the upper plate opening 13. The two track assemblies 40 respectively cooperate with the two ends of the fixed upper plate 21 to guide the fixed upper plate 21 to move.

[0061] Thus, the two track assemblies 40 can guide the movement of the fixed upper plate 21 so that, during the process of placing the roller 200, after one fixed upper plate 21 has placed the roller 200, it can move to the rear to facilitate the other fixed upper plate 21 to place the roller 200.

[0062] It is understandable that the structure of the track assembly 40 can be varied. The track assembly 40 may include a slide rail and a slider, with the slider located on both sides of the fixed upper plate 21. The track assembly 40 may also include a track component and a pulley, with the pulley located on both sides of the fixed upper plate 21. The pulley can slide along the track component. The track assembly 40 can guide the fixed upper plate 21 to move. This application does not impose any specific limitations.

[0063] Understandably, when the upper plate fixing assembly 20 and the lower plate fixing assembly 30 are arranged vertically, the track assembly 40 can be set horizontally to guide the upper plate 21 to move horizontally.

[0064] For further details, please refer to Figure 1 and Figure 7 The track assembly 40 includes an upper track plate 41 and a lower track plate 43. The upper track plate 41 and the lower track plate 43 are parallel and spaced apart. A guide groove 45 is formed at the spaced position between the upper track plate 41 and the lower track plate 43. The guide groove 45 cooperates with the fixed upper plate 21 to guide the fixed upper plate 21 to move along the guide groove 45.

[0065] In this way, not only can the fixed upper plate 21 be guided to move through the guide groove 45, but the upper track plate 41 and the lower track plate 43 can also limit the fixed upper plate 21, reducing the probability that the fixed upper plate 21 will detach from the guide groove 45.

[0066] Please see Figure 3 , Figure 5 and Figure 10 In this embodiment of the utility model, the housing 10 also includes a plurality of lower plate grooves 15. Along the feeding direction of the roller 200, the plurality of lower plate grooves 15 are arranged evenly in sequence at the bottom of the accommodating cavity 11. The lower plate grooves 15 are used to accommodate the lower plate fixing assembly 30.

[0067] Thus, the lower plate groove 15 can accommodate and limit the lower plate fixing component 30, and the lower plate fixing component 30 is located at the bottom of the accommodating cavity 11 in a simple and low-cost manner.

[0068] For further details, please refer to Figure 3 , Figure 5 and Figure 11 The lower plate fixing assembly 30 includes a first lower plate 33 and a second lower plate 35. The first lower plate 33 and the second lower plate 35 are arranged in sequence along the feeding direction of the roller 200. The first lower plate 33 is provided with a first plate groove 331 on the side near the second lower plate 35, and the second lower plate 35 is provided with a second plate groove 351 on the side near the first lower plate 33. The first plate groove 331 and the second plate groove 351 form a first limiting groove 31.

[0069] Thus, the second lower plate 35 can be placed in the lower plate groove 15 first, then one end of the roller 200 can be placed in the second plate groove 351, and then the first lower plate 33 can be placed in the lower plate groove 15. The first lower plate 33 and the second lower plate 35 surround to form a first limiting groove 31, thereby limiting one end of the roller 200, so that one end of the roller 200 can be taken out from or put into the first limiting groove 31.

[0070] Understandably, the feeding direction of the roller 200 is consistent with the moving direction of the guide fixed plate 21 of the track assembly 40, so as to facilitate multi-layer feeding of the roller 200. Understandably, multiple fixed plates 21 are also arranged sequentially along the feeding direction of the roller 200.

[0071] Please see Figures 1 to 3 , Figure 6 and Figure 7 In this embodiment of the utility model, the roller placement device 100 further includes a plurality of reinforcing ribs 50, which are disposed on the fixed upper plate 21.

[0072] Thus, the reinforcing rib 50 can enhance the strength of the fixed upper plate 21, making it easier for the fixed upper plate 21 to better bear and limit the roller 200.

[0073] For further details, please refer to 1 to 2. Figure 3 as well as Figures 6 to 8Multiple reinforcing ribs 50 are provided on the side of the fixed upper plate 21 away from the receiving cavity 11. The roller placement device 100 also includes a cover plate 60, which is provided at the end of the reinforcing rib 50 away from the fixed upper plate 21.

[0074] In this way, the shield 60 can cover the fixed upper plate 21, reducing the probability of dust falling onto the fixed upper plate 21 or the roller 200, and further ensuring that the accuracy of the roller 200 is not affected by dust.

[0075] Understandably, when the upper plate 21 and the lower plate fixing assembly 30 are set vertically, the baffle 60 can be located above the upper plate 21 to prevent dust from falling onto the upper plate 21 or the roller 200 under the action of gravity.

[0076] This utility model embodiment also provides a cleaning device, which includes a roller 200 and a roller placement device 100. The upper plate fixing component 20 limits one end of the roller 200, and the first limiting groove 31 accommodates and limits the end of the roller 200 away from the upper plate fixing component 20. The specific structure of the roller placement device 100 is as described in the above embodiments. Since this cleaning device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0077] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
