Description

Technical Field

[0001] This invention relates to the field of 3C product cleaning technology, specifically to a 3C product component cleaning device. Background Technology

[0002] With the rapid development of the 3C product market, the requirements for the cleanliness of components are becoming increasingly stringent. During production and use, 3C product components easily accumulate dust, oil, and other impurities. These impurities not only affect the product's appearance and performance but may also pose a potential threat to its long-term stability. Therefore, developing an efficient and reliable cleaning device for 3C product components has become an urgent problem to be solved in the industry. This device needs to be able to adapt to components of different sizes and shapes, ensuring that each component receives a thorough and uniform cleaning to meet increasingly stringent production and quality standards.

[0003] Existing 3C product component cleaning devices have several shortcomings in practical applications. First, during component transport, the lack of an effective scraping mechanism causes components to accumulate on the conveyor belt, leading to uneven cleaning and even blind spots, severely impacting cleaning effectiveness. Second, existing cleaning devices mostly employ a single cleaning method, failing to effectively remove stubborn stains from component surfaces and impurities from crevices, resulting in unsatisfactory cleaning results. Furthermore, the fixed brush head spacing in existing devices prevents flexible adjustment for components of different sizes, further limiting improvements in cleaning effectiveness. These problems not only reduce cleaning efficiency but also increase production costs, becoming bottlenecks restricting the quality and efficiency of 3C product production. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a 3C product component cleaning device, which solves the problems of component accumulation and poor cleaning effect in existing 3C product component cleaning devices, resulting in uneven cleaning and difficulty in removing stubborn stains and impurities from crevices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a 3C product component cleaning device, comprising a concave seat, a conveyor belt for conveying components installed inside the concave seat, a cleaning zone provided on the upper part of the concave seat, turntables rotatably mounted on both sides of the concave seat near the edges, one end of each turntable being connected to both ends of a drive shaft on the conveyor belt, and an eccentric rod hinged to the opposite sides of each turntable near the edge, a concave plate being laterally slidably mounted on the upper part of the cleaning zone, a limiting plate being connected between the two ends of the concave plate, the limiting plate passing through the cleaning zone, and a plurality of brush heads being equidistantly arranged at the bottom of the limiting plate.

[0006] Preferably, the conveyor belt has a mesh structure, which facilitates the filtration of cleaning fluid when cleaning parts.

[0007] Preferably, elongated guide grooves are provided on both sides of the cleaning area. The limiting plate passes through the guide grooves and is laterally slidably connected to the cleaning area. The guide grooves can provide a stable sliding track for the limiting plate, ensuring that the lateral movement of the limiting plate in the cleaning area is accurate and stable. The cooperative design of the limiting plate and the guide grooves can effectively prevent the limiting plate from deviating during movement and improve the stability of the device.

[0008] Preferably, the limiting plate has an internal cavity, and a diamond-shaped telescopic frame is hinged to one side of the cavity. A bolt rod is threaded through the outer side of the limiting plate, and one end of the bolt rod is rotatably connected to a moving block inside the cavity. The other end of the diamond-shaped telescopic frame is hinged to the side of the moving block away from the bolt rod. The design of the diamond-shaped telescopic frame allows for extension and retraction through the rotation of the bolt rod, thereby adjusting the spacing between the brush heads to meet the cleaning needs of parts of different sizes. The hinged design between the moving block and the diamond-shaped telescopic frame ensures the smoothness and accuracy of the extension and retraction process, avoiding uneven cleaning caused by improper extension and retraction.

[0009] Preferably, the bottom of the limiting plate is provided with a limiting groove communicating with the cavity. Several hollow movable seats are equidistantly and laterally slidably arranged within the limiting groove. The number of hollow movable seats is the same as the number of cross hinge points on the rhomboid telescopic frame. Each hollow movable seat is connected to its corresponding cross hinge point on the rhomboid telescopic frame via a shaft. A liquid outlet head is provided at the bottom of each hollow movable seat. The number of brush heads is the same as the number of hollow movable seats. Each brush head is rotatably connected to the liquid outlet head at the bottom of its corresponding hollow movable seat. The design of the hollow movable seats allows for equidistant lateral sliding of the brush heads via shafts connected to the cross hinge points of the rhomboid telescopic frame, ensuring uniformity in the cleaning process. The rotatable connection between the liquid outlet head and the brush head enables uniform spraying of the cleaning liquid and rotational wiping of the bristles, improving the cleaning effect.

[0010] Preferably, the limiting groove has slots on both sides, and the hollow moving seat has protrusions on both sides. The protrusions are laterally slidably engaged in the slots. The matching design of the slots and protrusions can provide a stable sliding track for the hollow moving seat, ensuring that the lateral movement of the hollow moving seat in the limiting groove is accurate and smooth. The engaging design of the protrusions and slots can effectively prevent the hollow moving seat from shifting during movement and improve the stability of the device.

[0011] Preferably, the brush head includes a guide cavity rotatably connected to the liquid outlet head at the bottom of the hollow movable seat. A tube is provided at the bottom of the guide cavity, and one side of the tube is densely covered with liquid outlet holes. Bristles are provided on the outer wall of the tube. The design of the guide cavity can evenly guide the cleaning liquid into the tube and spray it onto the surface of the parts through the liquid outlet holes to achieve efficient cleaning. The design of the bristles can physically wipe the surface of the parts, and together with the spraying of the cleaning liquid, achieve a comprehensive cleaning effect.

[0012] Preferably, a liquid inlet is provided on the outer side of the limiting plate away from the bolt rod. One end of the liquid inlet is connected to the side of the hollow moving seat near the liquid inlet via a connecting hose. The connecting hose communicates with the interior of the hollow moving seat. Each hollow moving seat is connected to another via a delivery hose for conveying cleaning fluid. The design of the liquid inlet facilitates the input of cleaning fluid and ensures that the cleaning fluid can be evenly distributed into each hollow moving seat. The design of the connecting hose and the delivery hose enables equidistant displacement of the hollow moving seats.

[0013] Preferably, the guide cavity includes a cylindrical cavity, the upper part of which is integrally formed with a cover cavity, and the inner wall of the cylindrical cavity is provided with a movable groove. An annular plate is fixedly installed in the movable groove, and a turbine fan is installed inside the annular plate. The design of the cover cavity can guide the cleaning liquid, ensuring that the cleaning liquid can flow evenly to the position of the turbine fan. The design of the turbine fan can drive itself to rotate through the flow of the cleaning liquid, thereby driving the annular plate and the guide cavity to rotate as a whole, realizing the rotational spraying of the tube and the rotational wiping of the bristles, further improving the cleaning effect.

[0014] This invention provides a cleaning device for 3C product components, which has the following advantages compared with the prior art: 1. This 3C product component cleaning device utilizes a conveyor belt linked to a turntable mechanism. This mechanism causes the concave plate and limiting plate to repeatedly move laterally within the cleaning area. During transport, accumulated components are effectively dispersed by the brush head, ensuring that each component is evenly distributed on the conveyor belt and avoiding cleaning blind spots caused by accumulation. This even distribution not only improves the comprehensiveness of cleaning but also significantly enhances cleaning efficiency, ensuring that every component receives thorough cleaning, thereby greatly improving the overall efficiency and effectiveness of the cleaning operation.

[0015] 2. This 3C product component cleaning device utilizes a bolt rod to drive the displacement of a moving block, thereby controlling the extension and retraction of the diamond-shaped telescopic frame, achieving flexible adjustment of the brush head spacing. This design fully considers the cleaning needs of components of different sizes. Through a precise adjustment mechanism, the spacing between the brush heads can be adjusted equidistantly according to the specific dimensions of the components. This flexible adjustment capability not only improves the applicability of the equipment, ensuring that components of various sizes receive proper cleaning, but also avoids uneven cleaning or excessive wear caused by improper brush head spacing, further enhancing the cleaning effect and the service life of the equipment.

[0016] 3. This 3C product component cleaning device uses a pipeline system to evenly spray cleaning solution onto the components during the cleaning process, while the bristles on the brush head meticulously wipe the components. This combined cleaning method fully utilizes the rinsing effect of the cleaning solution and the physical wiping effect of the brush bristles, effectively removing stains and impurities from the surface of the components, and even penetrating into the crevices of the components for thorough cleaning. This multi-layered cleaning mechanism not only greatly improves the cleaning effect of the components but also ensures the efficiency and comprehensiveness of the cleaning process, enabling each component to meet high standards of cleanliness.

[0017] 4. The ingenious design of the housing and turbine fan in this 3C product component cleaning device allows the cleaning fluid to flow through, driving the turbine fan to rotate, which in turn rotates the tube to spray out the cleaning fluid. The brush bristles then rotate and wipe, creating a dynamic cleaning effect. This rotating spraying mechanism not only expands the coverage area of ​​the cleaning fluid, allowing it to be sprayed more evenly to every corner of the components, but also enhances the wiping force of the bristles, ensuring that the components receive comprehensive and efficient cleaning. Furthermore, the rotating spraying effectively reduces cleaning fluid waste, improves resource utilization, and further enhances the economy and environmental friendliness of the cleaning operation, making the entire cleaning process more efficient and sustainable.

[0020] 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, and 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.

[0021] Please see Figures 1-7 This invention provides four technical solutions: Example 1 Please see Figures 1-2 In this embodiment of the invention, a 3C product component cleaning device includes a concave seat 1, a conveyor belt 2 for conveying components is installed inside the concave seat 1, a cleaning zone 3 is provided on the upper part of the concave seat 1, and turntables 4 are rotatably provided on both sides of the concave seat 1 near the edge. One end of each turntable 4 is connected to both ends of the drive shaft on the conveyor belt 2. An eccentric rod 5 is hinged to the opposite side of each turntable 4 near the edge. A concave plate 6 is laterally slidably sleeved on the upper part of the cleaning zone 3. A limiting plate 7 is connected between the two ends of the concave plate 6. The limiting plate 7 passes through the cleaning zone 3, and a plurality of brush heads 8 are equidistantly arranged at the bottom of the limiting plate 7.

[0022] In this embodiment, the 3C product components that need to be cleaned are poured onto the conveyor belt 2. The conveyor belt 2 transports the components. During the transport process, the two ends of the drive shaft on the conveyor belt 2 drive two turntables 4 to rotate. The turntables 4 cause the eccentric rod 5 to move eccentrically. The eccentric rod 5 causes the concave plate 6 to move laterally repeatedly in the cleaning area 3. The concave plate 6 drives the limiting plate 7 to move laterally repeatedly in the guide groove 31 in the cleaning area 3. In this way, the brush head 8 at the bottom of the limiting plate 7 will scrape apart the components accumulated on the conveyor belt 2, which facilitates the cleaning operation of the components.

[0023] For further details, please refer to Figure 1In this embodiment of the invention, the conveyor belt 2 has a mesh structure, which facilitates the filtration of cleaning liquid when cleaning parts.

[0024] For further details, please refer to Figures 1-2 In this embodiment of the invention, elongated guide grooves 31 are provided on both sides of the cleaning area 3. The limiting plate 7 passes through the guide grooves 31 and is laterally slidably connected to the cleaning area 3. The guide grooves 31 can provide a stable sliding track for the limiting plate 7, ensuring that the lateral movement of the limiting plate 7 in the cleaning area 3 is accurate and stable. The cooperative design of the limiting plate 7 and the guide grooves 31 can effectively prevent the limiting plate 7 from deviating during the movement and improve the stability of the device.

[0025] Example 2 differs from Example 1 in that: Please see Figures 3-4 In this embodiment of the invention, the limiting plate 7 has a cavity 71 inside, and a rhomboid telescopic frame 72 is hinged to one side of the cavity 71. A bolt rod 73 is screwed through the outer side of the limiting plate 7 by a thread. One end of the bolt rod 73 is rotatably connected to a moving block 74 inside the cavity 71. The other end of the rhomboid telescopic frame 72 is hinged to the side of the moving block 74 away from the bolt rod 73. The design of the rhomboid telescopic frame 72 can achieve extension and retraction by rotating the bolt rod 73, thereby adjusting the spacing between the brush heads 8 to meet the cleaning needs of parts of different sizes. The hinged design of the moving block 74 and the rhomboid telescopic frame 72 can ensure the stability and accuracy of the extension and retraction process, and avoid uneven cleaning caused by improper extension and retraction.

[0026] Please see Figures 2-5 In this embodiment of the invention, the bottom of the limiting plate 7 is provided with a limiting groove 75 communicating with the cavity 71. A plurality of hollow moving seats 76 are equidistantly and laterally slidably arranged in the limiting groove 75. The number of hollow moving seats 76 is the same as the number of cross hinge points on the rhomboid telescopic frame 72. Each hollow moving seat 76 is connected to the corresponding cross hinge point on the rhomboid telescopic frame 72 by a shaft. The bottom of the hollow moving seat 76 is provided with a liquid outlet head 77. The number of brush heads 8 is the same as the number of hollow moving seats 76. Each brush head 8 is rotatably connected to the liquid outlet head 77 at the bottom of its corresponding hollow moving seat 76. The design of the hollow moving seat 76 can be connected to the cross hinge point of the rhomboid telescopic frame 72 by a shaft, so as to realize the equidistant lateral sliding of the brush head 8 and ensure the uniformity of the cleaning process. The rotatable connection design between the liquid outlet head 77 and the brush head 8 can realize the uniform spraying of cleaning liquid and the rotation wiping of the bristles 84, thereby improving the cleaning effect.

[0027] In this embodiment, rotating the bolt rod 73 causes the moving block 74 to move within the cavity 71 of the limiting plate 7, thereby controlling the extension and retraction of the rhomboid telescopic frame 72. When the rhomboid telescopic frame 72 extends and retracts, the various cross hinge points on the rhomboid telescopic frame 72 will move at equal distances, thereby controlling the lateral equidistant movement of each hollow moving seat 76 in the limiting groove 75 at the bottom of the limiting plate 7. This allows for the lateral equidistant movement of each brush head 8, and the spacing between each brush head 8 can be adjusted equidistantly according to the size of the components.

[0028] For further details, please refer to Figures 4-5 In this embodiment of the invention, slots 712 are provided on both sides of the inner side of the limiting groove 75, and protrusions 711 are provided on both sides of the hollow moving seat 76. The protrusions 711 are laterally slidably engaged in the slots 712. The cooperative design of the slots 712 and the protrusions 711 can provide a stable sliding track for the hollow moving seat 76, ensuring that the lateral movement of the hollow moving seat 76 in the limiting groove 75 is accurate and stable. The engagement design of the protrusions 711 and the slots 712 can effectively prevent the hollow moving seat 76 from shifting during the movement, thereby improving the stability of the device.

[0029] Example 3 differs from Example 1 in that: Please see Figures 4-6 In this embodiment of the invention, the brush head 8 includes a guide cavity 82 rotatably connected to the liquid outlet head 77 at the bottom of the hollow movable seat 76. A tube body 81 is provided at the bottom of the guide cavity 82, and liquid outlet holes 83 are densely distributed on one side of the tube body 81. Brush bristles 84 are provided on the outer side wall of the tube body 81. The design of the guide cavity 82 can evenly guide the cleaning liquid to the tube body 81 and spray it onto the surface of the parts through the liquid outlet holes 83 to achieve efficient cleaning. The design of the brush bristles 84 can physically wipe the surface of the parts, and together with the spraying of the cleaning liquid, achieve a comprehensive cleaning effect.

[0030] Please see Figures 4-6 In this embodiment of the invention, a liquid inlet 78 is provided on the side of the limiting plate 7 away from the bolt rod 73. One end of the liquid inlet 78 is connected to the side of the hollow moving seat 76 near the liquid inlet 78 via a connecting hose 79. The connecting hose 79 communicates with the interior of the hollow moving seat 76. Each hollow moving seat 76 is connected to another via a delivery hose 710 for conveying cleaning fluid. The design of the liquid inlet 78 facilitates the input of cleaning fluid and ensures that the cleaning fluid can be evenly distributed into each hollow moving seat 76. The design of the connecting hose 79 and the delivery hose 710 enables the equidistant displacement of the hollow moving seats 76.

[0031] In this embodiment, during the scraping process, cleaning fluid is introduced into the inlet 78. The cleaning fluid enters each hollow movable seat 76 through the connecting hose 79 and the delivery hose 710, and then enters the tube body 81 through the outlet head 77 and the guide cavity 82. After that, it is sprayed out from each outlet hole 83 on the tube body 81 and sprayed onto the parts to rinse them. When the brush head 8 scrapes, the bristles 84 on the tube body 81 will wipe the parts, improving the cleaning effect of the parts.

[0032] Example 4 differs from Example 1 in that: Please see Figure 7 In this embodiment of the invention, the guide cavity 82 includes a cylindrical cavity 821. The upper part of the cylindrical cavity 821 is integrally formed with a cover cavity 822, and the inner wall of the cylindrical cavity 821 is provided with a movable groove 823. An annular plate 824 is fixedly disposed in the movable groove 823. A turbine fan 825 is installed inside the annular plate 824. The design of the cover cavity 822 can guide the cleaning liquid, ensuring that the cleaning liquid can flow evenly to the position of the turbine fan 825. The design of the turbine fan 825 can drive itself to rotate through the flow of the cleaning liquid, thereby driving the annular plate 824 and the guide cavity 82 to rotate as a whole, realizing the rotational spraying of the tube body 81 and the rotational wiping of the bristles 84, further improving the cleaning effect.

[0033] In this embodiment, when the cleaning fluid passes through the cover cavity 822, the cover cavity 822 guides the cleaning fluid to the position of the turbine fan 825. When the cleaning fluid passes through the turbine fan 825, it drives the turbine fan 825 to rotate. When the turbine fan 825 rotates, it drives the ring plate 824 to rotate. The ring plate 824 drives the guide cavity 82 to rotate as a whole. The guide cavity 82 drives the tube body 81 to rotate, causing the tube body 81 to rotate and spray out the cleaning fluid. Meanwhile, the bristles 84 rotate and wipe the cleaning parts, further improving the cleaning effect of the parts.

[0034] Working principle: The 3C product parts that need to be cleaned are poured onto the conveyor belt 2. The conveyor belt 2 transports the parts. During the transport process, the two ends of the drive shaft on the conveyor belt 2 drive the two turntables 4 to rotate. The turntables 4 cause the eccentric rod 5 to move eccentrically. The eccentric rod 5 causes the concave plate 6 to move laterally repeatedly in the cleaning area 3. The concave plate 6 drives the limiting plate 7 to move laterally repeatedly in the guide groove 31 in the cleaning area 3. In this way, the brush head 8 at the bottom of the limiting plate 7 will scrape apart the parts accumulated on the conveyor belt 2, making it easier to clean the parts. By rotating the bolt rod 73, the moving block 74 is moved within the cavity 71 of the limiting plate 7, thereby controlling the extension and retraction of the diamond telescopic frame 72. When the diamond telescopic frame 72 extends and retracts, the various cross hinge points on the diamond telescopic frame 72 will move at equal distances, thereby controlling the lateral equidistant movement of each hollow moving seat 76 in the limiting groove 75 at the bottom of the limiting plate 7, thereby controlling the lateral equidistant movement of each brush head 8, and adjusting the spacing between each brush head 8 at equal distances according to the size of the parts. During the scraping process, cleaning fluid is introduced into the inlet 78. The cleaning fluid enters each hollow movable seat 76 through the connecting hose 79 and the delivery hose 710, and then enters the tube body 81 through the outlet head 77 and the guide cavity 82. After that, it is sprayed out from each outlet hole 83 on the tube body 81 and sprayed onto the parts to rinse them. When the brush head 8 scrapes, the bristles 84 on the tube body 81 will wipe the parts to improve the cleaning effect of the parts. When the cleaning fluid passes through the cover cavity 822, the cover cavity 822 guides the cleaning fluid to the position of the turbine fan 825. When the cleaning fluid passes through the turbine fan 825, it drives the turbine fan 825 to rotate. When the turbine fan 825 rotates, it drives the ring plate 824 to rotate. The ring plate 824 drives the guide cavity 82 to rotate as a whole. The guide cavity 82 drives the tube body 81 to rotate, causing the tube body 81 to rotate and spray out the cleaning fluid. Meanwhile, the bristles 84 rotate and wipe the cleaning parts, further improving the cleaning effect of the parts.
