Description

Technical Field

[0001] This invention relates to the field of precision electronics manufacturing technology, specifically a cleaning structure for MINILED display panel products. Background Technology

[0002] In the manufacturing process of precision electronic components such as MINILED display panels, the cleaning process is a critical step to ensure product quality. Because the surface of a MINILED display panel integrates a large number of tiny LED chips and complex circuits, its cleaning must meet the technical requirements of being efficient, non-destructive, and thoroughly removing residues (such as flux, dust, fingerprints, etc.).

[0003] In the current production process of mini LED display products, the finished products are typically cleaned manually. This involves manually washing the cut products with a water gun, wiping them clean with a lint-free cloth, and then drying them with an air gun. This manual cleaning method is unsuitable for automated production, and as production volume increases, a significant number of additional workers are required.

[0004] Traditional cleaning methods often use fixed clamps or simple rotating platforms, which make it difficult to achieve precise positioning of the product during the cleaning process. Especially during rotary cleaning, the product is prone to displacement, tilting, or even falling off due to centrifugal force, resulting in uneven cleaning or damage to components. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning structure specifically designed for MINILED display panels, solving the problems of traditional cleaning methods for MINILED display panels, such as the inability to achieve automated cleaning, low cleaning efficiency, easy damage to the product, and incomplete cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cleaning structure specifically designed for MINILED display panels is characterized by comprising: a fixed body, a rotating body rotatably mounted inside the fixed body, a rotating connecting block fixedly mounted at the upper end of the rotating body, a lower base plate fixedly mounted at the upper end of the rotating connecting block, a plurality of lower support arms evenly arranged on the outer side of the lower base plate, a magnet fixedly mounted at the upper end of each lower support arm, a cylinder fixedly mounted at the middle position of the upper end of the rotating body, the upper end of the cylinder's telescopic rod connecting to an upper base plate through the lower base plate, and upper support arms evenly arranged on the outer side of the upper base plate, the upper support arms being located above the lower support arms and corresponding one-to-one with the lower support arms.

[0007] In a preferred embodiment, both the upper and lower support arms are Z-shaped. A slot and a block are provided between the lower side of the upper end of the upper support arm and the upper side of the lower support arm. The slot and the block are slidably arranged relative to each other. A through hole is provided at the upper end of the upper support arm. The magnet is located inside the slot and below the through hole.

[0008] In a preferred embodiment, the upper end of the cylinder's telescopic rod is in contact with the upper base plate, guide rods are evenly arranged on the lower side of the upper base plate, a guide sleeve is fixedly arranged on the lower base plate at the position corresponding to the guide rod, and a spring is arranged between the lower end of the guide rod and the lower side of the lower base plate.

[0009] In a preferred embodiment, the magnet is circular.

[0010] In a preferred embodiment, the upper support arm is made of a non-magnetic material.

[0011] In a preferred embodiment, the lower end of the lower support arm is detachably fixed to the lower base plate.

[0012] In a preferred embodiment, the lower base plate is provided with a rotating groove that is open at both the top and bottom. The lower end of the lower support arm is rotatably disposed inside the rotating groove. A positioning block is provided on the outer side of the lower end of the lower support arm, and the positioning block extends to the lower side of the lower base plate. The upper support arm is made of ferromagnetic material.

[0013] In a preferred embodiment, an annular baffle is fixedly installed on the outer side of the lower base plate and below the lower end of the lower support arm, and arc-shaped plates are symmetrically fixed on both sides of the lower support arm; when the lower support arm rotates inward and the lower end of the arc-shaped plate contacts the annular baffle, all the arc-shaped plates form a closed ventilation channel, and at this time the upper end of the arc-shaped plate is not lower than the height of the upper base plate. The lower base plate is provided with air inlet holes, and the upper base plate is uniformly provided with air distribution holes.

[0014] In a preferred embodiment, the magnet is square, and the inner end of the magnet extends to the inner upper end of the lower support arm.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Fully automated and efficient cleaning The system utilizes a robotic arm for automatic loading and unloading, along with a 360° rotating cleaning design driven by a rotating body. This achieves an integrated process of automatic product positioning, cleaning, and drying, significantly improving production efficiency. The coordinated operation of water spray nozzles and air blowers shortens the cleaning-drying cycle, adapting to the needs of large-scale production.

[0016] Dual magnetic fixation and precise guidance Magnets are used to hold products in place, and the perforated structure enables precise positioning, preventing product displacement or detachment during rotational cleaning. In Example 2, square magnets are used to hold the ferromagnetic upper support arm in place, replacing the physical guide structure and achieving magnetic guidance and automatic reset during lifting, thus simplifying the mechanical structure.

[0017] Dynamic ventilation and concentrated air drying technology The rotatable lower support arm and arc plate form a closed ventilation channel during the drying stage. Combined with the air inlet and the air outlet, the airflow is blown evenly upward from directly below the product, and the air concentration effect enhances the drying efficiency. It is especially suitable for deep dehydration of the raised structure of MINILED panels.

[0018] Structural simplification and cost optimization The invention has fewer components, which can reduce manufacturing and maintenance costs; the magnet has both fixing and guiding functions, achieving lightweight structure and functional integration. Attached Figure Description

[0030] The following embodiments will describe the present invention in detail with reference to the accompanying drawings. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention. Example 1

[0031] like Figure 1 and Figure 2 As shown, a cleaning structure specifically designed for MINILED display panels includes a fixed body 1, a rotating body 2 rotatably mounted inside the fixed body 1, a rotating connecting block 3 fixedly mounted at the upper end of the rotating body 2, a lower base plate 4 fixedly mounted at the upper end of the rotating connecting block 3, a plurality of lower support arms 5 evenly mounted on the outer side of the lower base plate 4, a magnet 6 fixedly mounted on the upper end of the lower support arm 5, a cylinder 7 fixedly mounted at the middle position of the upper end of the rotating body 2, the upper end of the telescopic rod of the cylinder 7 being connected to an upper base plate 8 through the lower base plate 4, and upper support arms 9 evenly mounted on the outer side of the upper base plate 8, the upper support arms 9 being located above the lower support arms 5 and corresponding one-to-one with the lower support arms 5.

[0032] like Figures 1 to 4 As shown, both the upper support arm 9 and the lower support arm 5 are Z-shaped. A slot 10 and a block 11 are provided between the lower side of the upper end of the upper support arm 9 and the upper side of the upper end of the lower support arm 5. The block 11 and the slot 10 are slidably arranged relative to each other. A through hole 12 is provided at the upper end of the upper support arm 9. The magnet 6 is located inside the slot 10 and below the through hole 12.

[0033] like Figure 1 and Figure 2As shown, the upper end of the telescopic rod of the cylinder 7 is in contact with the upper base plate 8. Guide rods 13 are evenly arranged on the lower side of the upper base plate 8. Guide sleeves 14 are fixedly arranged on the lower base plate 4 at the positions corresponding to the guide rods 13. A spring 15 is arranged between the lower end of the guide rods 13 and the lower side of the lower base plate 4.

[0034] like Figure 1 and Figure 2 As shown, magnet 6 is circular. The upper support arm 9 is made of non-magnetic material. The lower end of the lower support arm 5 is detachably fixed to the lower base plate 4.

[0035] like Figures 1 to 5 As shown, In this embodiment, the rotating body 2 is an accessory that rotates on the fixed body 1. It is connected to the rotating connecting block 3 and drives the rotating connecting block 3 and its upper structure to rotate together. The rotating connecting block 3 is connected to the rotating body 2 and rotates together. It is also connected to the lower base plate 4 and drives the upper structure to rotate. The cylinder 7 is fixedly installed in the middle of the rotating connecting block 3. The extension and retraction of the telescopic rod of the cylinder 7 can move the upper base plate 8 and the upper accessory. The cylinder 7 is the power source for the vertical movement of the upper accessory. The vertical linear movement of the upper accessory is achieved by the combination of the guide rod 13, the guide sleeve 14, and the spring 15 to achieve positioning, guidance, and return. When the cylinder 7 extends, the upper accessory rises; when the cylinder 7 retracts, the upper accessory moves downward under the action of the spring 15. There is a slot 10 and a locking block 11 between the upper support arm 9 and the lower support arm 5. When the locking block 11 is located in the slot 10, the rotation of the lower support arm 5 can drive the rotation of the upper support arm 9. At the same time, the upper support arm 9 will not detach from the lower support arm 5 during the up-and-down movement, ensuring stable and smooth up-and-down movement. A magnet 6 is installed on the lower support arm 5. When the upper support arm 9 lowers the product 23, the magnet 6 can fix and attract the product 23. When the upper support arm 9 raises the product 23, the magnet 6 can separate from the product 23, so that the automated robotic arm can remove the product 23.

[0036] The workflow of this embodiment is as follows: the automated robotic arm places the product 23 onto the upper support arm 9. The upper support arm 9 descends, causing the product 23 to descend as well, so that the magnet 6 fixes and attracts the product 23. Then, the rotating body 2 rotates, causing the lower support arm 5 and the upper support arm 9 to rotate. The product 23 rotates, and water spray nozzles located around the device are used to clean the top and bottom of the product. After cleaning, air blowers located around the device blow away the water droplets or moisture on the product. The upper support arm 9 then lifts the product 23, causing the magnet 6 to separate from the product 23. Finally, the automated robotic arm removes the product 23.

[0037] In this embodiment, the upper support arm 9 has a through hole 12 at its upper end, into which the iron sheet of product 23 is inserted. This serves two purposes: firstly, it guides and positions the product; secondly, it facilitates the adsorption and contact between magnet 6 and product 23 after the upper support arm 9 descends; and thirdly, during the rotation cleaning process, the through hole 12 can also position the product to prevent product 23 from flying out during rotation. Example 2

[0038] like Figure 6 As shown, a cleaning structure specifically for MINILED display panel products includes a fixed body 1, a rotating body 2 rotatably disposed inside the fixed body 1, a rotating connecting block 3 fixedly disposed at the upper end of the rotating body 2, a lower base plate 4 fixedly disposed at the upper end of the rotating connecting block 3, a plurality of lower support arms 5 evenly disposed on the outer side of the lower base plate 4, a magnet 6 fixedly disposed at the upper end of the lower support arms 5, and a cylinder 7 fixedly disposed at the middle position of the upper end of the rotating body 2. Figure 4 As shown in the image, you can refer to... Figure 1 The upper end of the telescopic rod of cylinder 7 is connected to upper base plate 8 through lower base plate 4. Upper support arms 9 are evenly and fixedly arranged on the outer side of upper base plate 8. Upper support arms 9 are located above lower support arms 5 and correspond one-to-one with lower support arms 5. Both upper support arms 9 and lower support arms 5 are Z-shaped. A slot 10 and a block 11 are provided between the lower side of the upper end of upper support arm 9 and the upper side of the upper end of lower support arm 5. The block 11 and the slot 10 are slidably arranged vertically relative to each other. A through hole 12 is provided at the upper end of upper support arm 9. Magnet 6 is located inside the slot 10 and below the through hole 12. The above structure is consistent with the structure of embodiment one.

[0039] like Figure 6 and Figure 9 As shown, the lower base plate 4 is provided with a rotating groove 16 that is open at both the top and bottom. The lower end of the lower support arm 5 is rotatably set inside the rotating groove 16. A positioning block 17 is provided on the outer side of the lower end of the lower support arm 5. The positioning block 17 extends to the lower side of the lower base plate 4. The upper support arm 9 is made of ferromagnetic material.

[0040] like Figures 6 to 9 As shown, an annular baffle 18 is fixedly installed on the outer side of the lower base plate 4 and below the lower end of the lower support arm 5. Curved plates 19 are symmetrically fixed on both sides of the lower support arm 5. When the lower support arm 5 rotates inward and the lower end of the curved plate 19 contacts the annular baffle 18, all the curved plates 19 form a closed ventilation channel 20. At this time, the upper end of the curved plate 19 is not lower than the height of the upper base plate 8. An air inlet 21 is provided on the lower base plate 4, and a distribution air hole 22 is evenly provided on the upper base plate 8. The magnet 6 is square, and its inner end extends to the inner side of the upper end of the lower support arm 5.

[0041] like Figures 6 to 9 As shown, The structure of this embodiment two is similar to that of embodiment one. Compared with embodiment one, the magnet 6 in this embodiment two not only serves to attract the product 23, but also attracts the upper support arm 9 when it rises, thus acting as a guide. The inner side of the upper end of the lower support arm 5 slides relative to the outer side of the upper support arm 9. As the upper support arm 9 rises, the lower support arm 5 rotates inward. The magnet 6 prevents the upper support arm 9 from deviating from the upper position of the lower support arm 5. Therefore, the magnet 6 also has a certain guiding function, which can replace the function of the guide rod 13 and guide sleeve 14 in embodiment one. Even if the locking block 11 disengages from the slot 10 when the upper support arm 9 rises, the locking block 11 can return to the inside of the slot 10 due to the attraction of the upper support arm 9 by the magnet 6. This setting is simpler in structure and has a lower production cost compared to embodiment one. In addition, the two sides of the lower support arm 5 in this embodiment two... The device is equipped with a fixed arc-shaped plate 19. When the lower support arm 5 rotates inward and the lower end of the arc-shaped plate 19 contacts the annular baffle 18, all the arc-shaped plates 19 form a closed ventilation channel 20. During the cleaning process, there will be gaps between the upper parts of the arc-shaped plates 19, and the water spray heads around the device can still clean the upper and lower sides of the product 23. When it is necessary to blow away water droplets and water vapor, after cleaning, the upper support arm 9 can be raised first, and the product will be detached from the magnet 6. All the arc-shaped plates 19 will form a cylindrical shape, and the interior of the arc-shaped plates 19 is the ventilation channel 20. At this time, it is only necessary to ventilate through the air inlet 21, and then the air enters into the ventilation channel 20. The air then disperses through the air dispersion vent 22 and the gap between the upper bottom plate 8 and the arc-shaped plate 19, blowing from directly below the product 23. Moreover, the lower bottom plate 4, the ventilation channel 20 and the upper bottom plate 8 form a chamber, which has the effect of concentrating air. Since the product is now detached from the magnet 6, an upper blower head is positioned above the device and directly opposite the product 23. This upper blower head blows air onto the product 23 from above, not only removing water droplets or moisture from the top of the product 23 but also counteracting the upward force exerted on the product 23 by the lower blower head, thus keeping the product 23 stable and preventing it from being moved by the blower head. Because the lower part of the product 23 has many protruding structures, blowing air onto the product 23 from the lower front is more effective at removing water droplets and moisture, and a better blowing effect can be achieved by simply placing one blower head at the top and one at the bottom of the product 23.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
