[0063] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.
[0064] The trays can stack and transport multiple phone cases. After use, the trays need to be cleaned, usually manually by staff to reuse them and save costs. However, manual cleaning of the trays is labor-intensive and has low automation.
[0065] Embodiments of this application provide a cleaning device, including a housing assembly, a guiding assembly, a positioning assembly, and a cleaning assembly. The housing assembly includes a connected box and a door. The box forms a receiving cavity with an opening for material to enter and exit the cavity. The door is used to cover or open the opening. The guiding assembly includes two guide plates mounted opposite each other along a first direction. Each guide plate has a guide groove communicating with the opening to guide material into and out of the receiving cavity along a second direction perpendicular to the first direction. The positioning assembly is disposed in the receiving cavity and connected to the guide plates to stop material entering from the opening and to position the material. The cleaning assembly includes a suction member and multiple air jets. The air jets are located on opposite sides of the guiding assembly along a third direction and are used to blow air towards the material to clean dust adhering to the material. The suction member is connected to the box and communicates with the receiving cavity, and is used to draw air into the receiving cavity to remove dust from the cavity.
[0066] In the aforementioned cleaning equipment, material enters the receiving cavity through the opening along the guide groove. A positioning component stops the material to maintain its position, and a door seals the opening. Air is sprayed onto the material by the jet nozzle to blow off dust adhering to it. The sealed cavity allows the suction component to generate significant suction, removing the dust from the material and the cavity itself, thus cleaning the material. When used to clean pallets, the combination of air blowing and suction achieves a cleaner finish, enabling pallet reuse and offering a high degree of automation.
[0067] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0068] Please see Figure 1 and Figure 2 An embodiment of this application provides a cleaning device 100 for cleaning materials so that the cleaned materials can be reused.
[0069] In some embodiments, the material is a tray, which is used to carry the phone case so that it can be transferred during the processing of the phone case.
[0070] Please see Figures 1 to 4 The cleaning device 100 includes a housing assembly 10, a guide assembly 30, a positioning assembly 20, and a cleaning assembly 40. The housing assembly 10 is used to mount the guide assembly 30, the positioning assembly 20, and the cleaning assembly 40. The guide assembly 30 guides material to a preset position. The positioning assembly 20 positions the material at the preset position. The cleaning assembly 40 cleans the material at the preset position.
[0071] Please see Figure 1 and Figure 2 The housing assembly 10 includes a connected housing 11 and a door 12. (See also...) Figure 3 The housing 11 forms a receiving cavity with an opening 1101. The door 12 is also used to open the opening 1101, allowing material to enter and exit the receiving cavity through the opening 1101. The door 12 is also used to cover the opening 1101, thereby sealing the receiving cavity. A preset position is located within the receiving cavity.
[0072] Please see Figure 3 and Figure 4 Both the guiding assembly 30 and the positioning assembly 20 are disposed within the receiving cavity. The guiding assembly 30 includes two guide plates 31 mounted opposite each other along a first direction Z. Each guide plate 31 has a guide groove 3101. The guide groove 3101 extends along a second direction X and communicates with the opening 1101. The thickness of the tray is less than that of the guide groove 3101, allowing the tray to stand upright and enter and exit the receiving cavity from the opening 1101 along the second direction X under the guidance of the guide groove 3101. The positioning assembly 20 is connected to the guide plate 31 and is used to stop material entering from the opening 1101, thereby positioning the material at a preset position.
[0073] The cleaning assembly 40 includes a suction component 42 and multiple jet components 41. The jet components 41 are located on opposite sides of the guide assembly 30 along a third direction Y and are used to blow air towards the material to clean dust adhering to it, causing the dust to be blown off. The suction component 42 is connected to the housing 11 and communicates with the receiving cavity. The suction component 42 is used to draw air into the receiving cavity to remove dust from within. The sealed receiving cavity allows the suction component 42 to generate greater suction force, further removing dust adhering to the material and improving the cleaning effect.
[0074] Therefore, by combining the blowing air from the jet component 41 and the suction air from the suction component 42, the material can be cleaned more thoroughly, the material can be reused, and the degree of automation is high.
[0075] In some embodiments, the second direction X is perpendicular to the first direction Z, which facilitates the movement of the tray along the guide groove 3101.
[0076] In the illustrated embodiment, the first direction Z is parallel to the vertical direction, and the second direction X is parallel to the horizontal direction. The tray can be placed upright, exposing most of the tray to the receiving cavity for easy cleaning.
[0077] In some embodiments, the first direction Z forms a preset angle with the vertical direction. Placing the tray at an angle to the vertical direction can reduce the height of the box 11.
[0078] In the illustrated embodiment, the third direction Y is parallel to the horizontal direction, causing the gas blown by the jet component 41 to clean both sides of the upright tray, resulting in a large cleaning area. The front of the tray is the side that holds the phone case, and the back of the tray faces away from the front.
[0079] In some embodiments, the second direction X forms a preset angle with the third direction Y.
[0080] In some embodiments, the second direction X is perpendicular to the third direction Y, so that the jet 41 can blow air directly onto the tray, thereby enhancing the cleaning effect of the jet 41 on the tray.
[0081] See Figure 3 and Figure 4 In some embodiments, the extension directions of the guide plate 31 and the guide groove 3101 are both parallel to the second direction X. The guide plate 31 is provided with two protruding ribs 32 spaced apart along the third direction Y, so that the two protruding ribs 32 can form the guide groove 3101.
[0082] In some embodiments, the protruding rib 32 is configured as an elongated strip to facilitate the processing of the guide assembly 30 and to form a guide groove 3101.
[0083] In some embodiments, the ridge 32 is configured as a discontinuous dotted line, that is, one ridge 32 includes multiple protrusions 321, which are spaced apart along the second direction X at a preset interval to expose the material, so that the ridge 32 blocks less material, which is beneficial to cleaning the material. The larger the preset interval, the smaller the area of material blocked by the ridge 32, and the more thorough the cleaning of the material.
[0084] In some embodiments, the positioning component 20 includes a positioning block 21 and a pusher block 121. The positioning block 21 is disposed on the guide plate 31. The pusher block 121 is disposed on the door 12. The pusher block 121 is used to push material toward the positioning block 21 when the door 12 covers the opening 1101.
[0085] When the door 12 covers the opening 1101, the push block 121 pushes the material, causing the material to move along the guide groove 3101 until it contacts the positioning block 21. At this time, the push block 121 and the positioning block 21 clamp the material on opposite sides along the second direction X, and the two guide plates 31 clamp the material on opposite sides along the first direction Z. The material is positioned in a preset position.
[0086] In some embodiments, the positioning block 21 is located in the guide groove 3101 to restrict material movement.
[0087] In some embodiments, the receiving cavity has two openings 1101. The housing assembly 10 includes two doors 12. Each door 12 covers one opening 1101. The two openings 1101 are disposed opposite each other along a second direction X. A positioning block 21 is disposed at the center of the guide plate 31 along the second direction X.
[0088] Materials are placed into the two openings 1101 respectively, and the openings 1101 are covered by the two doors 12 to push the materials toward the positioning block 21 until the materials contact the positioning block 21. At this time, the doors 12 are connected to the box body 11, and the two materials are respectively positioned on both sides of the positioning block 21 along the second direction X, so that the cleaning device 100 can clean two materials at the same time, which can improve the cleaning efficiency of the cleaning device 100.
[0089] Please see Figure 3 and Figure 4 In some embodiments, the jet element 41 includes a positive pressure air source 411 (see...). Figure 2 The system comprises multiple connecting rods 412 and multiple nozzles 413. The multiple connecting rods 412 are spaced apart along a second direction X and all extend along a first direction Z. Each connecting rod 412 is equipped with multiple nozzles 413, and the multiple nozzles 413 connected to one connecting rod 412 are spaced apart along the first direction Z. All multiple nozzles 413 are connected to a positive pressure air source 411, which drives the multiple nozzles 413 to blow air towards the material along a third direction Y to clean dust from the material.
[0090] There are two jet nozzles 41, which are arranged parallel to each other and spaced apart along the third direction Y to clean the material on both sides of the third direction Y, that is, to clean the front and back of the tray.
[0091] Multiple nozzles 413 are provided to cover and clean both sides of the material. Each nozzle 413 is small, which makes the air pressure of the gas sprayed by the nozzle 413 greater, thus improving the cleaning effect.
[0092] In some embodiments, the positive pressure air source 411 is a centrifugal fan.
[0093] In some embodiments, the cleaning assembly 40 further includes a water storage unit 43. The water storage unit 43 is used to store liquid, and the suction unit 42 is connected to the water storage unit 43 so that dust is drawn into the water storage unit 43 by the suction unit 42.
[0094] In some embodiments, the cleaning assembly 40 further includes a water reservoir 43. The water reservoir 43 is used to store liquid. The suction member 42 is connected to the water reservoir 43. The suction member 42 draws dust into the water reservoir 43. The dust is soluble in the liquid, thereby cleaning the dust and preventing it from flying around.
[0095] In some embodiments, the liquid is a cleaning agent.
[0096] Please see Figure 3 In some embodiments, the housing 11 includes a bottom plate 111, a side plate 112, and a top plate 113. The side plate 112 is connected between the top plate 113 and the side plate 112 to form a receiving cavity. An opening 1101 is provided in the side plate 112. The bottom plate 111 is horizontally arranged.
[0097] In some embodiments, the water reservoir 43 is an open water tank 431. The water tank 431 is located below the positioning assembly 20. The water reservoir 43 is slidable relative to the bottom plate 111 and the side plate 112 to enter the receiving cavity. The water tank 431 has an opening 4311 facing the positioning assembly 20, allowing dust in the receiving cavity to fall downwards into the water tank 431 through the opening 4311 and dissolve in the cleaning agent within the water tank 431.
[0098] In some embodiments, the housing assembly 10 further includes a cutout plate 114. The cutout plate 114 is connected to the side plate 112 and located in the receiving cavity.
[0099] The water storage component 43 is located below the perforated plate 114. The guide component 30 and the jet component 41 are located on the side of the perforated plate 114 facing away from the water storage component 43, so that dust can fall into the water storage component 43 through the perforated plate 114 and the slot 4311.
[0100] In some embodiments, the upper surface of the perforated plate 114 is used to fix the connecting rod 412 and a guide plate 31 for the installation of the guide assembly 30 and the jet 41.
[0101] Please see Figure 5 In some instances, the water storage component 43 has a water exchange port 4312 on the side away from the receiving cavity (see [reference]). Figure 2 The water storage component 43 is inclined toward the water exchange port 4312, so that the extension direction of the water storage component 43 forms an angle α with the horizontal plane. During water exchange, the liquid flows toward the water exchange port 4312 under the action of gravity, making it convenient to extract the liquid from the water storage component 43 from the water exchange port 4312. In addition, the water storage component 43 can also slide relative to the bottom plate 111 and the side plate 112 to remove the water storage tank 431 for thorough cleaning.
[0102] In some embodiments, the included angle α is between 0° and 20°. When the included angle α is 1°, the water storage component 43 is slightly tilted towards the water exchange port 4312. When the included angle α is 20°, the tilt of the water storage component 43 towards the water exchange port 4312 increases, and the liquid flows faster towards the water exchange port 4312 due to gravity, allowing the liquid to be replaced in the water storage component 43 to be extracted more quickly. The larger the included angle α is, the greater the tilt of the water storage component 43 towards the water exchange port 4312, and the faster the liquid flows towards the water exchange port 4312 due to gravity, allowing the liquid to be extracted from the water storage component 43 more quickly. However, when the included angle α is too large, such as 45°, the liquid accumulates at the end near the water exchange port 4312, and the liquid is prone to overflow. The end away from the water exchange port 4312 has no liquid, which can easily affect dust collection.
[0103] Please see Figure 3 and Figure 5 In some embodiments, two pads 1111 are spaced apart on the base plate 111. The two pads 1111 are spaced apart along the third direction Y. When the water storage component 43 is located in the receiving cavity, the pads 1111 contact the bottom of the water storage component 43, so that the end of the water storage component 43 away from the water exchange port 4312 is spaced apart from the base plate 111, and the water storage component 43 is tilted toward the water exchange port 4312.
[0104] In some embodiments, the base plate 111 is further provided with two limiting blocks 1112. The two limiting blocks 1112 are respectively provided on opposite sides of the water storage component 43 along the third direction Y, so that the water storage component 43 corresponds to the pad block 1111 and stops the water storage component 43 to prevent the water storage component 43 from shaking when moving relative to the base plate 111, causing the end of the water storage component 43 away from the water exchange port 4312 to be unable to contact the pad block 1111.
[0105] Please see Figure 2In some embodiments, the suction component 42 includes a vacuum generator 421 and a dust collection hood 422. The dust collection hood 422 is disposed on the top plate 113 and communicates with the receiving cavity, and is disposed opposite to the bottom plate 111. The vacuum generator 421 is connected to both the dust collection hood 422 and the water storage component 43 to draw dust from the receiving cavity to the water storage component 43, so that the dust can dissolve in the liquid in the water storage component 43.
[0106] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of disclosure of this application.
