Description

Technical Field

[0001] This invention relates to the field of thin film dust removal technology, and in particular to a dust removal device for a thin film processing production line. Background Technology

[0002] In the thin film processing industry, the cleanliness of the thin film surface directly determines the final quality and performance of the product, especially in high-precision applications such as electronic thin films and optical thin films. Therefore, the thin film processing production line must be equipped with efficient dust removal devices. Currently, most mainstream thin film dust removal devices in the industry are designed based on the core logic of "surface cleaning and dust collection".

[0003] In existing technologies, when the filter screen becomes clogged to a certain extent, the machine must be stopped to replace or clean the filter screen. For film processing companies that pursue high production capacity, frequent shutdowns will directly lead to a reduction in the effective operating time of the production line, which will seriously restrict the improvement of production efficiency. On the other hand, the maintenance process relies on manual operation, which increases labor costs. Summary of the Invention

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, referring to Figures 1-11 This is the first embodiment of the present invention. This embodiment provides a dust removal device for a thin film processing production line, including a main structure 1, including a processing equipment 11. A negative pressure fan 12 is provided on the top of the processing equipment 11. Negative pressure pipes 13 are connected to both sides of the negative pressure fan 12 and are fixedly connected to the processing equipment 11. A dust collection pipe 14 is connected to one side of the negative pressure pipe 13. The bottom of the dust collection pipe 14 penetrates the processing equipment 11 and extends into the processing equipment 11. A dust removal roller 15 is provided at the bottom of the dust collection pipe 14 and is fixedly connected to the inner cavity of the processing equipment 11.

[0035] The processing equipment 11 provides a working space for film processing and dust removal. The negative pressure fan 12 generates negative pressure suction, which serves as the power source for dust collection. The negative pressure pipe 13 connects the negative pressure fan 12 and the dust collection pipe 14 to form a dust conveying channel and is fixed to the processing equipment 11 to ensure structural stability. The bottom of the dust collection pipe 14 extends into the processing equipment 11, which can accurately collect the dust on the film surface cleaned by the dust removal roller 15. The dust removal roller 15 directly contacts the film surface to physically clean the dust first, thus laying the foundation for subsequent negative pressure collection and preventing the dust from spreading inside the processing equipment 11.

[0036] The switching component 2 includes a filter plate 21 disposed in the inner cavity of the negative pressure pipe 13. A first movable block 22 is fixedly connected to the top of the filter plate 21. A first through groove 23 is opened at the top of the negative pressure pipe 13. The top of the first movable block 22 passes through the first through groove 23 and is fixedly connected to a connecting plate 24. A second movable block 25 is fixedly connected to the bottom of the filter plate 21. A second through groove 26 is opened at the bottom of the negative pressure pipe 13. The bottom of the second movable block 25 passes through the second through groove 26 and is hinged to a movable rod 27. A sealing plate 28 is hinged to the surface of the movable rod 27. An embedded groove 29 is opened on one side of the bottom of the negative pressure pipe 13 and cooperates with the sealing plate 28.

[0037] The filter plate 21 is installed inside the negative pressure pipe 13 to filter dust and prevent blockage of the negative pressure fan 12. The first movable block 22 and the second movable block 25 are fixed to the top and bottom of the filter plate 21 respectively, and can slide along the first through groove 23 and the second through groove 26 to drive the filter plate 21 to move. The connecting plate 24 connects the first movable blocks 22 on both sides, so that the filter plates 21 on both sides can move synchronously, thereby realizing the coordinated action when the flow channel is switched. The movable rod 27 hinges the second movable block 25 and the sealing plate 28. When the filter plate 21 moves, the movable rod 27 drives the sealing plate 28. The sealing plate 28 cooperates with the embedded groove 29 to realize the sealing or opening of the negative pressure pipe 13 on one side, thereby ensuring that the dust removal is not interrupted when the flow channel is switched.

[0038] The cleaning component 3 includes an energy storage component 31 disposed on both sides of the filter plate 21, a cleaning component 32 disposed on the inner side of the filter plate 21, and a backwash component 33 disposed on the outer side of the filter plate 21.

[0039] The energy storage component 31 provides power storage and reset for the movement of the filter plate 21; the cleaning component 32 directly performs mechanical cleaning of the dust on the surface of the filter plate 21; and the backflushing component 33 cleans the stubborn dust in the mesh of the filter plate 21 by backflushing the airflow. The two work together to achieve comprehensive cleaning of the filter plate 21, thereby reducing manual intervention.

[0040] Example 2, refer to Figures 1-11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the energy storage component 31 includes grooves 311 formed on both sides of the inner cavity of the negative pressure pipe 13. A frame 312 is slidably connected to the inner cavity of the groove 311. A swing block 313 is rotatably connected to the inner cavity of the frame 312. A spring 314 is fixedly connected to the surface of the swing block 313 and is fixedly connected to the inner cavity of the frame 312. A first spring 315 is fixedly connected to the surface of the frame 312 and is fixedly connected to the inner cavity of the groove 311.

[0042] The groove 311 provides installation and sliding space for the frame 312; the frame 312 can slide in the groove 311, and the swing block 313 in its inner cavity is elastically reset by the spring 314. The swing block 313 can block and limit the movement of the filter plate 21, so that the filter plate 21 accumulates a sufficient pressure difference in the early stage of blockage, thereby avoiding the movement triggered by slight blockage; the first spring 315 connects the frame 312 and the groove 311. When the pressure of the filter plate 21 is large enough, it can push the swing block 313 and the frame 312 to compress the first spring 315 and release the kinetic energy of the movement of the filter plate 21.

[0043] Specifically, the cleaning component 32 includes a rotating sleeve 321 that penetrates the inner side of the filter plate 21. The rotating sleeve 321 is rotatably connected to the filter plate 21 via a bearing. A fixing rod 322 is slidably connected to the inner cavity of the rotating sleeve 321. A driving block 323 is fixedly connected to the top of the inner cavity of the rotating sleeve 321. A driving groove 324 is opened on the surface of the fixing rod 322 and cooperates with the driving block 323. An installation rod 325 is fixedly connected to the top of the rotating sleeve 321. A cleaning brush 326 is rotatably connected to the surface of the installation rod 325.

[0044] The rotating sleeve 321 passes through the inner side of the filter plate 21 and is rotatably connected by a bearing, allowing it to rotate relative to the filter plate 21. The fixing rod 322 is fixed inside the negative pressure pipe 13, and the rotating sleeve 321 can slide along the fixing rod 322. When sliding, the driving block 323 cooperates with the driving groove 324 to convert the linear sliding of the rotating sleeve 321 into rotational motion. The mounting rod 325 is fixed to the top of the rotating sleeve 321 and rotates synchronously with the rotating sleeve 321. The cleaning brush 326 on its surface can directly contact the surface of the filter plate 21. When the rotating sleeve 321 rotates, it drives the cleaning brush 326 to sweep away dust, thereby preventing dust accumulation and clogging of the filter plate 21 mesh, thus eliminating the need for manual disassembly and cleaning, thereby improving cleaning efficiency.

[0045] Specifically, a first gear 327 is fixedly connected to the surface of the cleaning brush 326, a second gear 328 is meshed on the surface of the first gear 327, and it is rotatably connected to the top of the rotating sleeve 321. A toothed ring 329 is meshed on the surface of the second gear 328, and it is fixedly connected to the filter plate 21.

[0046] The first gear 327 is fixed to the surface of the cleaning brush 326, and the second gear 328 is rotatably connected to the top of the rotating sleeve 321 and meshes with the first gear 327. The gear ring 329 is fixed to the filter plate 21 and meshes with the second gear 328. When the rotating sleeve 321 drives the mounting rod 325 and the cleaning brush 326 to revolve around the fixed rod 322, the second gear 328 rolls on the tooth surface of the gear ring 329, causing the second gear 328 to rotate. In turn, the first gear 327 drives the cleaning brush 326 to rotate, so that the cleaning brush 326 and the surface of the filter plate 21 form opposing friction. Therefore, compared with simple revolving cleaning, it can remove stubborn dust more thoroughly. At the same time, the centrifugal force generated by the rotation can cause the dust on the surface of the cleaning brush 326 to fall off, thereby realizing the self-cleaning of the cleaning brush 326.

[0047] Specifically, a limiting block 3251 is fixedly connected to the top of the outer side of the mounting rod 325, and a limiting groove 3252 is opened on the surface of the filter plate 21, which cooperates with the limiting block 3251.

[0048] When the rotating sleeve 321 drives the mounting rod 325 to rotate around the fixed rod 322, the limiting block 3251 slides along the limiting groove 3252, which guides the movement trajectory of the mounting rod 325, thereby preventing the mounting rod 325 from shifting due to centrifugal force or airflow impact, thus ensuring that the cleaning brush 326 always adheres to the surface of the filter plate 21, thereby avoiding blind spots in cleaning due to shifting and ensuring uniform and stable cleaning effect.

[0049] Specifically, the backflushing component 33 includes a slide rod 331 fixedly connected to the outside of the filter plate 21. A sliding sleeve 332 is slidably connected to the side of the slide rod 331 away from the filter plate 21 and is fixedly connected to the inner cavity of the negative pressure pipe 13. A second spring 333 is fixedly connected to the surface of the slide rod 331 and is fixedly connected to the inner cavity of the sliding sleeve 332. Both sides of the sliding sleeve 332 are open.

[0050] The slide rod 331 is fixed to the outside of the filter plate 21, and the sliding sleeve 332 is fixed to the inner cavity of the negative pressure pipe 13 and slides in cooperation with the slide rod 331. The cooperation of the two guides the movement of the filter plate 21, thereby preventing the filter plate 21 from tilting and getting stuck when it moves. The second spring 333 connects the slide rod 331 and the sliding sleeve 332. When the filter plate 21 moves to one side, it drives the slide rod 331 to stretch or compress the second spring 333. The elastic force of the second spring 333 can help the filter plate 21 to reset when it is blocked. The sliding sleeve 332 has openings on both sides, which allows the slide rod 331 to extend and retract freely, thus not hindering the movement of the filter plate 21.

[0051] Specifically, a piston cylinder 334 is provided on the side of the sliding sleeve 332 away from the filter plate 21 and is fixedly connected to the inner cavity of the negative pressure pipe 13. A piston rod 335 is slidably connected to the inner side of the piston cylinder 334. A third spring 336 is fixedly connected to the surface of the piston rod 335 and is fixedly connected to the inner cavity of the piston cylinder 334. An exhaust pipe 337 is connected to one side of the surface of the piston cylinder 334. A connecting pipe 338 is connected to the exhaust pipe 337 away from the piston cylinder 334 and is fixedly connected to the inner cavity of the negative pressure pipe 13. A nozzle 339 is connected to the surface of the connecting pipe 338. The inner side of the connecting pipe 338 is fixedly connected to the fixing rod 322.

[0052] The piston cylinder 334 is fixed to the inner cavity of the negative pressure pipe 13, and the piston rod 335 is slidably connected to the inner side of the piston cylinder 334. When the filter plate 21 drives the slide rod 331 to extend out of the slide sleeve 332, the slide rod 331 pushes the piston rod 335 to compress the third spring 336, compressing the gas in the piston cylinder 334. The exhaust pipe 337 connects the piston cylinder 334 and the connecting pipe 338. The compressed gas enters the connecting pipe 338 through the exhaust pipe 337 and is then sprayed out through the nozzle 339, forming a high-pressure airflow that backwashes the filter plate 21, thereby removing fine dust from the mesh.

[0053] Specifically, an intake pipe 3310 is connected to the other side of the piston cylinder 334, and a one-way valve 3311 is fixedly connected to the surfaces of both the intake pipe 3310 and the exhaust pipe 337.

[0054] The intake pipe 3310 connects the piston cylinder 334 to the outside and is used to replenish gas. The exhaust pipe 337 and the one-way valve 3311 on the surface of the intake pipe 3310 ensure that the intake pipe 3310 can only take in gas and the exhaust pipe 337 can only exhaust gas, thereby preventing gas from flowing back from the exhaust pipe 337 when the piston rod 335 is reset, or the compressed gas from leaking from the intake pipe 3310. When the piston rod 335 is reset under the action of the third spring 336, a negative pressure is formed in the piston cylinder 334. The outside gas enters the piston cylinder 334 through the intake pipe 3310 in one direction, preparing for the next compression and gas storage, thereby ensuring that the recoil component 33 can cyclically provide recoil airflow, thus eliminating the need for an additional gas source.

[0055] Specifically, the first movable block 22 is fixedly connected to both sides of the first outer cover 221, and the second movable block 25 is fixedly connected to both sides of the second outer cover 251.

[0056] The first outer cover 221 is fixed to both sides of the first movable block 22, covering the connection between the first through groove 23 and the first movable block 22; the second outer cover 251 is fixed to both sides of the second movable block 25, covering the connection between the second through groove 26 and the second movable block 25.

[0057] Working principle: When the processing equipment 11 processes the film, the dust removal roller 15 contacts the film surface and cleans the dust on the film surface; then the negative pressure fan 12 is started, and the negative pressure suction generated is transmitted to the dust collection pipe 14 through the negative pressure pipe 13. The dust collection pipe 14 sucks the dust cleaned by the dust removal roller 15 into the negative pressure pipe 13, and then filters the dust through the filter plate 21 in the negative pressure pipe 13, thereby preventing dust from entering the negative pressure fan 12 and causing blockage, thus ensuring the normal operation of the negative pressure system.

[0058] As usage time increases, dust accumulates and clogs the surface of one side of the filter plate 21, causing an increase in the pressure difference between the two sides of the filter plate 21. The pressure difference pushes the filter plate 21 to one side. At this time, the swing block 313 in the groove 311 of the negative pressure pipe 13 blocks the filter plate 21, causing the filter plate 21 to enter the power storage stage. When the blockage worsens, the pressure difference overcomes the resistance of the swing block 313, pushing the swing block 313 and the frame 312 to slide into the groove 311 and compress the first spring 315. As the swing block 313 disengages from the filter plate 21, the filter plate 21 moves rapidly under the action of the pressure difference and the restoring force of the second spring 333, thereby triggering subsequent cleaning and switching actions.

[0059] When the filter plate 21 moves, it drives the inner rotating sleeve 321 to slide along the fixed rod 322. The driving block 323 in the inner cavity of the rotating sleeve 321 cooperates with the driving groove 324 on the surface of the fixed rod 322, causing the rotating sleeve 321 to rotate. The rotating sleeve 321 drives the top mounting rod 325 and the cleaning brush 326 to revolve around the fixed rod 322. At the same time, the limiting block 3251 on the outer side of the mounting rod 325 slides along the limiting groove 3252 on the surface of the filter plate 21 to ensure stable movement. Then, the first gear 327 and the second gear 328 on the surface of the cleaning brush 326 mesh. The second gear 328 meshes with the toothed ring 329 fixed to the filter plate 21, causing the second gear 328 to roll and drive the cleaning brush 326 to rotate. This causes the dust on the surface of the filter plate 21 to be cleaned by opposing friction, which can ensure effective cleaning. At the same time, the centrifugal force generated by the rotation causes the dust on the surface of the cleaning brush 326 to fall off, thereby realizing the self-cleaning of the cleaning brush 326.

[0060] At the same time, the filter plate 21 drives the outer slide rod 331 to slide along the slide sleeve 332. After the slide rod 331 extends out of the slide sleeve 332, it pushes the piston rod 335 in the piston cylinder 334, compressing the third spring 336. The gas in the piston cylinder 334 enters the connecting pipe 338 through the exhaust pipe 337, and is sprayed out with high-pressure airflow through the nozzle 339 to backwash the dust in the mesh of the filter plate 21, thereby achieving deep cleaning and completing the comprehensive self-cleaning of the filter plate 21.

[0061] As the filter plate 21 moves, the second movable block 25 at the bottom slides along the second through groove 26, driving the sealing plate 28 to move via the movable rod 27, so that the sealing plate 28 is embedded in the embedding groove 29 at the bottom of the negative pressure pipe 13, sealing the current side negative pressure pipe 13; at the same time, the first movable block 22 at the top of the filter plate 21 slides along the first through groove 23, driving the other side filter plate 21 to move synchronously via the connecting plate 24; the other side filter plate 21 drives the sliding rod 331 to stretch the second spring 333, and its corresponding piston rod 335 is activated by the third spring 336. When the filter plate 21 is reset, external gas enters the piston cylinder 334 through the air inlet pipe 3310 (the one-way valve 3311 controls the air intake) to replenish the gas. When the filter plate 21 on the other side contacts the swing block 313 in the corresponding groove 311, it pushes the swing block 313 to swing into the frame 312 and compresses the spring 314. Then the spring 314 resets and drives the swing block 313 to limit the filter plate 21 on the other side. At the same time, the sealing plate 28 on the other side moves away from the embedded groove 29 and opens the negative pressure pipe 13 on the other side, thereby realizing the flow channel switching and ensuring that dust removal is not interrupted.

[0062] Example 3, referring to Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0063] Specifically, a cleaning port is provided on the side of the negative pressure pipe 13 away from the negative pressure fan 12, and an inspection door 131 is fixedly connected to the inner cavity of the cleaning port.

[0064] If it is necessary to clean the dust inside the negative pressure pipe 13, the inspection door 131 of the negative pressure pipe 13 can be opened for operation, thereby ensuring the continuous and stable operation of the device.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
