[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the following detailed description, reference can be made to the accompanying drawings, which form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized, or structural, logical, or electrical changes may be made to the embodiments of the present application.

[0033] To address the aforementioned problems, this application proposes an automatic cleaning device, comprising: a flexible support member, a vibration motor, a cleaning assembly, a fastening assembly, and a control module. The flexible support member supports the vibration motor and the cleaning assembly, and the fastening assembly holds the object to be cleaned. The flexible support member and the fastening assembly are mounted on a workbench. The cleaning assembly includes a connecting rod passing through the flexible support member. A first end of the connecting rod is connected to the vibration motor, and a second end of the connecting rod has a cleaning head. The distance between the first end of the connecting rod and the flexible support member is greater than the distance between the second end of the connecting rod and the flexible support member. The flexible support member is movably mounted near the fastening assembly so that the cleaning head can contact the object to be cleaned on the fastening assembly. The control module controls the operation of the vibration motor, the cleaning assembly, and the fastening assembly, so that the cleaning assembly performs the cleaning process on the object to be cleaned.

[0034] In the cleaning device of this application embodiment, a flexible support member supports the vibration motor and the cleaning assembly, allowing the vibration motor to transmit vibration energy to the cleaning head of the cleaning assembly. When the target object to be cleaned is, for example, a used mobile phone, the cleaning head can contact the used mobile phone in a high-frequency vibration manner, which can thoroughly clean the dust and dirt on the used mobile phone, allowing it to enter the used trading process more quickly. This application cleverly uses a flexible support member to assemble the vibration motor and the cleaning assembly, which has the advantages of simple structure, ingenious design, and easy maintenance. In particular, this application embodiment utilizes the lever working principle. When the connecting rod passes through the through hole, and the distance between the first end of the connecting rod and the flexible support member is greater than the distance between the second end of the connecting rod and the flexible support member, the contact point between the connecting rod and the flexible support member serves as the fulcrum, making the vibration amplitude of the second end of the connecting rod greater than the vibration amplitude of the first end, effectively amplifying the vibration amplitude of the cleaning head.

[0035] According to an embodiment of this application, the flexible support includes a limiting part, a supporting part, and a fixing part. The limiting part is connected to the fixing part through the supporting part, and the limiting part and the fixing part are parallel to each other to form an I-shaped support. The limiting part has a through hole, the size of which is adapted to the size of the connecting rod. Setting the flexible support in an I-shape ensures the stability of the flexible support during operation. The through hole in the upper part of the I-shaped flexible support facilitates better cooperation with the connecting rod to form a lever structure.

[0036] According to an embodiment of this application, the flexible support further includes a pressure plate with a groove, and a limiting portion with a groove. When the pressure plate is installed on the limiting portion, the pressure plate and the groove on the limiting portion form a through hole. The through hole formed by the pressure plate and the groove on the limiting portion can fix the cleaning assembly, prevent the cleaning assembly from shifting during vibration, and is flexible to assemble and disassemble, and easy to maintain.

[0037] According to an embodiment of this application, the fixing part includes one or more fixing holes, and the distance from the center of the fixing hole to the top surface of the limiting part is 45-50 mm. The distance from the center of the fixing hole to the top surface of the limiting part is a key factor affecting the working effect of the flexible support. A distance of 45-50 mm from the center of the fixing hole to the top surface of the limiting part can ensure the cleaning effect of the cleaning head.

[0038] According to an embodiment of this application, the width of the support portion is 20-25 mm. The width of the support portion is a key factor affecting the working effect of the flexible support member; a width of 20-25 mm ensures the cleaning effect of the cleaning head.

[0039] According to an embodiment of this application, the fixing part includes one or more fixing holes, the distance from the center of the fixing hole to the top surface of the limiting part is 48 mm, and the width of the support part is 22 mm.

[0040] It should be noted that the above-mentioned size settings or size requirements for the I-shaped flexible support in the embodiments of this application are the final size range that can be selected in industry after a large number of experiments and adjustments, rather than an arbitrarily set parameter range. For example, when the distance from the center of the fixing hole to the top surface of the limiting part is between 45-50 mm (e.g., 48 mm) and the width of the support part is between 20-25 mm (e.g., 22 mm), the cleaning device as a whole can achieve a better cleaning effect. In particular, the cleaning head supported on the I-shaped flexible support can maximize the cleaning efficiency, and the cleaning effect is stable after long-term operation, and the components are not easily damaged.

[0041] According to an embodiment of this application, the thickness of the flexible support member is 10-15 mm, and the hardness of the flexible support member is HD80-90. When the thickness of the flexible support member is 10-15 mm and the hardness of the flexible support member is HD80-90, the vibration amplitude of the flexible support member can be guaranteed to be within a reasonable range.

[0042] According to an embodiment of this application, the system further includes a flexible spacer and a rigid fastener, the rigid fastener being fixed to the worktable, and the flexible support being connected to the rigid fastener via the flexible spacer. Fixing the flexible support to the worktable using the flexible spacer and rigid fastener improves the operational stability of the flexible support.

[0043] According to an embodiment of this application, the cleaning head includes a brush with a liquid passage filled with cleaning fluid. When the brush is in operation, the cleaning fluid wets the brush, improving the cleaning effectiveness.

[0044] According to an embodiment of this application, the fastening assembly includes a support portion and a lifting portion. The support portion is used to support the object to be cleaned and is disposed below the lifting portion. The lifting portion can press or release the object to be cleaned on the support portion by adjusting the height of its lower end. When the fastening assembly presses the object to be cleaned, it ensures that the object does not move during cleaning, thus ensuring the cleaning effect.

[0045] According to an embodiment of this application, the lifting part includes a cylinder and a clamping block, the clamping block being elastically connected to the cylinder by a spring; one or more suction cups are provided on the support part. The suction cups on the support part can adsorb the object to be cleaned onto the surface of the support part, preventing the object to be cleaned from moving during cleaning.

[0046] According to an embodiment of this application, the system further includes: a transverse slide rail and a longitudinal slide rail. The transverse slide rail is disposed on the worktable, and the longitudinal slide rail is disposed on the transverse slide rail, allowing the longitudinal slide rail to move laterally as a whole. The flexible support member is fixed to the longitudinal slide rail, allowing the flexible support member to move longitudinally as a whole. The transverse and longitudinal slide rails provide lateral and longitudinal movement for the flexible support member, enabling the cleaning components on the flexible support member to clean different locations of the target object to be cleaned.

[0047] According to embodiments of this application, the target object to be cleaned includes electronic devices. Headphone jacks, speaker holes, and charging ports in electronic devices (such as smartphones, tablets, gaming devices, etc.) easily accumulate dust. An automatic cleaning device can easily and thoroughly clean the dust from electronic devices. Therefore, the automatic cleaning device of this application is particularly suitable for bulk cleaning of used electronic products, achieving high-quality and efficient cleaning results.

[0048] According to another aspect of this application, an automatic cleaning method is proposed. This automatic cleaning method is based on the aforementioned automatic cleaning device. The method includes: the control module controlling the fastening component to actuate and press against the target object to be cleaned; the control module activating a vibration motor; the control module controlling the transverse and / or longitudinal slide rails to move the cleaning component to a first position to clean the target object; and, in response to the vibration motor operating for a predetermined time, the control module controlling the transverse and / or longitudinal slide rails to move the cleaning component to a second position to clean different positions of the target object. By utilizing the control module to control the operating sequence of the fastening component, the transverse and / or longitudinal slide rails, and the vibration motor, the target object to be cleaned is automatically cleaned, improving work efficiency.

[0049] According to an embodiment of this application, the method further includes: in response to the completion of the cleaning operation, the control module controls the transverse slide rail and / or the longitudinal slide rail to return to the starting position, and the control module controls the fastening assembly to release the cleaned target object. After the work is completed, the transverse slide rail and / or the longitudinal slide rail return to the starting position, preparing for the next operation.

[0050] According to an embodiment of this application, during operation, the control module controls the speed of the vibration motor to be within the range of 3000-10000 rpm, which is beneficial for thoroughly cleaning the dust and dirt on the target object to be cleaned, such as non-new or second-hand electronic devices, and can effectively reduce the operating noise of the vibration motor.

[0051] The above describes various implementations of the automatic cleaning device according to the embodiments of this application. The following provides specific examples and, in conjunction with the accompanying drawings, schematically describes the optional configurations and usage methods of the embodiments of this application.

[0052] Figure 1This is a schematic diagram of an automatic cleaning device according to an embodiment of the present invention. As shown, the automatic cleaning device 100 includes a moving module 110, a cleaning module 120, a fastening assembly 130, and a worktable 140. The moving module 110 and the fastening assembly 130 are fixed on the worktable 140, and the cleaning module 120 is mounted on the moving module 110. The fastening assembly 130 is used to hold the object to be cleaned. The cleaning module 120 is mounted near the fastening assembly 130, and the cleaning module 120 can clean different positions of the object to be cleaned on the fastening assembly 130 by moving with the moving module 110. The automatic cleaning device 100 controls the working sequence of the moving module 110, the cleaning module 120, and the fastening assembly 130 according to a set cleaning program, automatically cleaning the object to be cleaned, reducing manual operation, and improving cleaning efficiency.

[0053] In one embodiment, the object to be cleaned can be various products placed on the cleaning device, especially electronic devices such as mobile phones, tablets, and computers. Headphone jacks, charging ports, and speaker holes on electronic devices easily accumulate dust and are difficult to clean. The automatic cleaning device 100 can quickly and easily clean dust from various tiny pores on electronic devices.

[0054] Figure 2A This is a schematic diagram of the structure of a cleaning module according to an embodiment of the present invention. Figure 2B This is a structural schematic diagram of the cleaning module assembly state according to an embodiment of the present invention; Figure 2C This is a structural schematic diagram of a flexible support member according to an embodiment of the present invention. Figure 2A As shown, the cleaning module 120 includes a flexible support 121, a cleaning assembly 122, and a vibration motor 123. The cleaning assembly 122 includes a connecting rod 1221 that passes through the flexible support 121. The first end of the connecting rod 1221 is connected to the vibration motor 123, and the second end is connected to a cleaning head 1222. The connecting rod 1221 can transfer the vibration energy from the vibration motor 123 to the cleaning head 1222, which can clean the object to be cleaned. The flexible support 121 supports the cleaning assembly 122 and the vibration motor 123. The flexible support 121 is movably mounted near the fastening assembly 130 so that the cleaning head 1222 can contact the object to be cleaned on the fastening assembly 130.

[0055] In one embodiment, the cleaning head 1222 includes a brush with a liquid passage filled with cleaning fluid. When the brush 1222 is in operation, the cleaning fluid in the liquid passage is injected into the brush, improving the cleaning effect on the target object. The brush 1222 is made of stiff nylon bristles. Stiff nylon bristles have good dust removal effect and do not damage the target object to be cleaned.

[0056] In one embodiment, the distance between the first end of the link 1221 and the flexible support 121 is greater than the distance between the second end of the link 1221 and the flexible support 121. (Reference) Figure 2B The vibrating motor 123 includes a flange 1231, which is fixedly connected to the first end of the connecting rod 1221. Taking the contact point between the connecting rod 1221 and the flexible support 121 as the fulcrum, when the distance between the first end of the connecting rod 1221 and the flexible support 121 is greater than the distance between the second end of the connecting rod 1221 and the flexible support 121, the flexible support 121, the cleaning assembly 122, and the vibrating motor 123 form a lever structure. Utilizing the lever principle, the connecting rod 1221 can amplify the vibration amplitude of the vibrating motor 123, making the vibration amplitude of the cleaning head 1222 greater than that of the vibrating motor 123. Thus, the cleaning device, especially the vibrating motor, can obtain a larger amplitude with less energy consumption, maximizing the cleaning efficiency of the entire machine.

[0057] refer to Figure 2C The flexible support member 121 includes a limiting part 1211, a supporting part 1212, and a fixing part 1213. The limiting part 1211 is connected to the fixing part 1213 through the supporting part 1212. The limiting part 1211 and the fixing part 1213 are parallel to each other, forming an I-shaped support member. The limiting part 1211 has a through hole, the size of which is adapted to the size of the connecting rod 1221. In one embodiment, the limiting part 1211, the supporting part 1212, and the fixing part 1213 are integrally formed.

[0058] refer to Figure 2A The flexible support 121 further includes a pressure plate 124, which has a groove. The limiting portion 1211 also has a groove. When the pressure plate 124 is mounted on the limiting portion 1211, the grooves on the pressure plate 124 and the limiting portion 1211 form a through hole. The pressure plate 124 can be fixed to the limiting portion 1211 with bolts to confine the connecting rod 1221 within the through hole. By clamping the connecting rod 1221 within the through hole, the pressure plate 124 improves the operational stability of the cleaning assembly 122.

[0059] In one embodiment, the flexible support 121 is made of rubber and urethane, with a thickness of 10-15 mm and a hardness of HD80-90. The flexible support 121 supports the cleaning assembly 122 and the vibration motor 123. Furthermore, the flexible support 121, utilizing its flexibility, provides conditions for the vibration motor 123 to vibrate. When the hardness of the flexible support 121 is too low, the vibration motor 123 will cause the cleaning assembly 122 to swing excessively, significantly reducing the cleaning effect and even causing destructive damage to the object being cleaned. When the hardness of the flexible support 121 is too high, the vibration motor 123 will generate significant noise during operation, and the cleaning effect will be poor. Preferably, the flexible support 121 has a thickness of 12 mm and a hardness of HD84-88. When the thickness of the flexible support 121 is 12 mm and the hardness is HD84-88, it can provide the cleaning assembly 122 with the best cleaning effect and effectively reduce operating noise.

[0060] In one embodiment, the fixing part 1213 includes one or more fixing holes 1214, the distance from the center of the fixing hole 1214 to the top surface of the limiting part 1211 is 45-50 mm; the width of the supporting part 1212 is 20-25 mm. Further, the distance from the center of the fixing hole 1214 to the top surface of the limiting part 1211 is 48 mm; the width of the supporting part 1212 is 22 mm. When the distance from the center of the fixing hole 1214 to the top surface of the limiting part 1211 is 48 mm and the width of the supporting part 1212 is 22 mm, the flexible support 121 can provide the optimal vibration amplitude, ensuring the cleaning effect of the cleaning assembly 122.

[0061] refer to Figure 2B The cleaning module 120 further includes a flexible isolator 125 and a rigid fastener 126. The rigid fastener 126 can be fixed to the worktable 140, and the flexible support 121 is connected to the rigid fastener 126 through the flexible isolator 125. The flexible isolator 125 is made of rubber and urethane, and is used to buffer the impact force caused by vibration during the operation of the flexible support. The rigid fastener 126 is made of rubber and urethane, and is used to fix the flexible support 121, thereby improving the working stability of the cleaning module 120.

[0062] The vibratory motor 123 includes an eccentric block, which is fixedly mounted on the rotor shaft. The high-speed rotation of the rotor shaft and the eccentric block generates centrifugal force to produce excitation force. In one embodiment, the rotational speed of the vibratory motor 123 is 3000-10000 r / min. At 3000-10000 r / min, the vibratory motor provides good cleaning performance on the target object and generates relatively low noise.

[0063] In one embodiment, the automatic cleaning device 100 includes multiple cleaning modules 120, which are sequentially fixed to a worktable 140 or a moving module 110. The multiple cleaning modules 120 can receive unified instructions to clean multiple target objects simultaneously, improving the working efficiency of the automatic cleaning device. Alternatively, the multiple cleaning modules 120 can also receive instructions individually and operate independently to meet the needs of different usage scenarios.

[0064] Figure 3 This is a schematic diagram of a fastening assembly according to an embodiment of the present invention. As shown, the fastening assembly 130 includes a support frame 131, a lifting part 132, and a bearing part 133. The support frame 131 is fixed to a worktable 140, the lifting part 132 is movably mounted on the support frame 131, and the bearing part 133 is fixed to the worktable 140 and disposed below the lifting part 132. The lifting part 132 can press or release the cleaning target on the bearing part 133 by adjusting the height of its lower end.

[0065] The support frame 131 includes two parallel columns, which can be made of aluminum alloy profiles. The lifting unit 132 includes a pressure plate 1321, a pressure block 1322, and a cylinder 1324. The cylinder 1324 can be fixed to the horizontal plate 1311 of the support frame 131. The cylinder 1324 is fixedly connected to the pressure plate 1321, and the cylinder 1324 can drive the pressure plate 1321 to move up and down.

[0066] The clamping block 1322 is elastically connected to the pressure plate 1321 by a spring 1323. When the clamping block 1322 contacts the target object during descent, the spring 1323 contracts without applying excessive pressure to the target object. The clamping block 1322, elastically connected to the pressure plate 1321 by the spring 1323, allows the fastening assembly 130 to hold target objects of varying thicknesses without damaging them. The cylinder 1324 can be mounted on the opposite side of the column or fixed to the horizontal plate 1311 of the support frame 131. The cylinder 1324 includes a piston rod capable of reciprocating motion. One end of the piston rod is fixedly connected to the pressure plate 1321, and the cylinder drives the pressure plate 1321 to move up and down. In one embodiment, the lifting unit 132 includes multiple clamping blocks 1322, which operate simultaneously, improving work efficiency.

[0067] The support portion 133 includes one or more limiting grooves for supporting the object to be cleaned. The width of the limiting groove is greater than the width of the object to be cleaned. In one embodiment, one or more suction cups 134, which can be vacuum suction cups, are provided on the bottom surface of the limiting groove. The one or more suction cups 134 are embedded in the grooves on the bottom surface of the limiting groove, such that the suction cups are parallel to or slightly higher than the bottom surface of the limiting groove. When the object to be cleaned is placed in the limiting groove, the suction cups 134 adsorb the object to be cleaned within the limiting groove, preventing movement during the cleaning process. Those skilled in the art will understand that other holding structures, such as grippers, can also be provided on the limiting groove to hold the object to be cleaned in the limiting groove.

[0068] Figure 4 This is a schematic diagram of a moving module according to an embodiment of the present invention. As shown, the moving module 110 includes a transverse slide rail 111 and a longitudinal slide rail 112. The transverse slide rail 111 is disposed on the worktable 140, and the longitudinal slide rail 112 is disposed on the transverse slide rail 111, enabling the longitudinal slide rail 112 to move laterally as a whole. The transverse slide rail 111 includes two parallel transverse rails, and a servo motor 1111 is mounted on at least one rail. The servo motor 1111 is used to drive the structure on the rail to move laterally.

[0069] The longitudinal slide rail 112 is fixed to the transverse slide rail 111 by a support plate 1121. The lower surface of the support plate 1121 may include a slider that can be embedded in the two parallel tracks of the transverse slide rail 111. The longitudinal slide rail 112 includes two parallel longitudinal tracks, and a servo motor 1122 is mounted on at least one track. The servo motor 1122 is used to drive the elastic platform 121 on the track to move longitudinally. The longitudinal slide rail 112 includes a mounting base 1123, which is fixedly connected to the fixing block 126 of the cleaning module 120, so that the cleaning module 120 as a whole can move longitudinally.

[0070] The transverse slide rail 111 and the longitudinal slide rail 112 each include anti-collision blocks 113, which are respectively disposed at both ends of the transverse slide rail 111 and the longitudinal slide rail 112. The anti-collision blocks 113 are made of materials including but not limited to rubber and polyurethane. The anti-collision blocks 113 can prevent the transverse slide rail 111 and the longitudinal slide rail 112 from moving beyond their normal operating range. In addition, the anti-collision blocks 113 have an energy-absorbing function, so that the transverse slide rail 111 and the longitudinal slide rail 112 will not be damaged when they collide with the anti-collision blocks 113.

[0071] Figure 5 This is a schematic diagram of an automatic cleaning device according to an embodiment of the present invention. As shown in the figure, the automatic cleaning device includes an upper housing 101 and a lower housing 102, wherein the upper housing 101 is fixed to the lower housing 102. The upper housing 101 houses an automatic cleaning device 100.

[0072] An indicator light 103 is installed on the top of the upper housing 101. The indicator light 103 can use different colors to indicate the working status of the automatic cleaning equipment.

[0075] Figure 6 This is a flowchart of an automatic cleaning method according to an embodiment of the present invention. As shown, in step S601, the automatic cleaning equipment is started, and the fastening component actuates to press the object to be cleaned. Specifically, the operator places the object to be cleaned on the support portion, starts the automatic cleaning equipment, and the control module controls the lifting portion on the fastening component to descend, contacting the object to be cleaned and pressing it down. The control module also controls the vibrating suction cup to draw air to adsorb the object to be cleaned into the groove of the support portion.

[0076] In step S602, the vibration motor is activated, controlling the moving module to move the cleaning component to the first position to clean the target object. Specifically, the control module controls the operation of the horizontal and / or vertical slide rails in the moving module to move the cleaning component on the moving module to the first position to clean the target object. The first position can be the location where the brush in the cleaning component can contact the target object. For example, assuming the target object is a new or used mobile phone, the first position can be the location where the brush makes contact with the speaker hole on one side of the phone; assuming the target object is an item such as a used inkstone, the first position can be the location where the brush contacts the left side of the upper surface of the inkstone.

[0077] In step S603, after the vibration motor has operated for a predetermined time, the moving module moves the cleaning component to a second position to clean different areas of the object to be cleaned. For example, the predetermined time is in the range of 3-10 seconds. When the cleaning component has operated for the predetermined time in the first position, the control module controls the horizontal slide rail and / or the vertical slide rail to move the cleaning component to the second position. The second position can be an adjacent position to the first position. For example, when the object to be cleaned is a mobile phone, the second position can be the position where the brush just contacts the speaker hole on the other side of the phone; for example, when the object to be cleaned is an inkstone, the second position can be the position where the brush contacts the right side area of ​​the upper surface of the inkstone.

[0078] In step S604, in response to the completion of the cleaning operation, the moving module returns to the starting position, and the fastening assembly releases the cleaned object. Specifically, when the entire cleaning process is completed, the control module controls the moving module to return to the starting position or default position to prepare for the next cleaning operation. The control module can control the lifting part in the fastening assembly to rise and release the cleaned item.

[0079] This application utilizes a control module to automatically control the working sequence of the moving module, cleaning module, and fastening components, thereby standardizing the cleaning operation and ensuring cleaning quality; the automatic cleaning device can clean items in batches, which can significantly improve work efficiency.

[0080] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of the invention.
