Abstract
Description
Technical Field
[0001] This utility model relates to a cleaning device, and more particularly to a plasma cleaning device. Background Technology
[0002] Before the assembled lens is further assembled into a camera module, dust ions remain on the lens inside the lens due to transportation and contact with air, which will affect the final photo taking of the mobile phone or camera. If the contaminated lens is directly assembled into the mobile phone, the mobile phone needs to be disassembled to complete the cleaning, which is a very troublesome process. Therefore, the lens needs to be cleaned after the lens is assembled.
[0003] Currently, lens cleaning typically involves workers using cotton swabs to remove contaminants. This method is time-consuming, labor-intensive, inefficient, and doesn't provide a thorough cleaning. Therefore, there is an urgent need for a more efficient and effective lens cleaning device. Utility Model Content
[0004] The purpose of this invention is to provide a plasma cleaning device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0005] The solution to the technical problem of this utility model is:
[0006] A plasma cleaning device includes: a base with an internal air passage, an air intake component for introducing air into the air passage on at least one side of the base, and an air outlet communicating with the air passage on the top side of the base; a carrier plate connected to the top side of the base, a ventilation groove on the bottom side of the carrier plate, the air outlet communicating with the ventilation groove, and a plurality of positioning grooves on the top side of the carrier plate, each of the positioning grooves having a through hole communicating with the ventilation groove at its bottom; and a mold connected to the top side of the carrier plate, the mold being capable of covering the plurality of positioning grooves.
[0007] This technical solution has at least the following beneficial effects: The workpiece to be cleaned is placed in the positioning groove of the carrier plate, and the positioning groove is used to limit the workpiece. Then, the carrier plate is moved to the top side of the base. At this time, the air outlet on the top side of the base is connected to the ventilation groove on the bottom side of the carrier plate. The pressure mold is connected to the top side of the carrier plate, covering multiple positioning grooves on the top side of the carrier plate. The air intake component is connected to the external plasma supply equipment. The plasma is input into the air passage through the air intake component. The plasma is output from the air outlet to the ventilation groove. The ventilation groove can provide space for the plasma to flow, so that the plasma can flow to the corresponding through hole position and enter the through hole at the bottom of multiple positioning grooves to clean the workpiece. The active particles in the plasma react chemically or physically with the contaminants on the surface of the workpiece, thereby cleaning the surface. During this process, the pressure mold can limit the workpiece to prevent it from moving out of the positioning groove. Therefore, this utility model can clean multiple workpieces at the same time, which greatly improves the cleaning efficiency of the workpiece and effectively removes the contaminants on its surface, thus improving the cleaning quality.
[0008] As a further improvement to the above technical solution, pressure blocks are respectively provided in the mold at the positions corresponding to the multiple positioning slots, and clearance slots are respectively provided on the bottom sides of the multiple pressure blocks. The multiple pressure blocks abut against the top side of the carrier plate. When the mold is connected to the top side of the carrier plate, the multiple pressure blocks in the mold abut against the top side of the carrier plate. At this time, the workpieces in the multiple positioning slots on the carrier plate are respectively located in the clearance slots of the multiple pressure blocks, and the clearance slots allow the workpieces to be positioned, which is especially suitable for limiting the height of workpieces.
[0009] As a further improvement to the above technical solution, the mold includes a cover plate and a fixing plate. The top side of the fixing plate is provided with a plurality of fixing holes. The plurality of pressing blocks are respectively movably connected to the plurality of fixing holes. The cover plate is connected to the top side of the fixing plate. The fixing plate is connected to the top side of the carrier plate. Elastic elements are respectively provided between the cover plate and the plurality of pressing blocks. The plurality of elastic elements can respectively press the plurality of pressing blocks down into the plurality of fixing holes. The pressure block is installed into the fixing hole on the top side of the fixing plate and can move up and down within the fixing hole. The cover plate is connected to the top side of the fixing plate. The cover plate presses down on the pressure block through the elastic element, so that the pressure block is at the bottom of the stroke position. At this time, the pressure block protrudes downward from the fixing hole. When the fixing plate is connected to the top side of the carrier plate, the bottom side of the pressure block first abuts against the top side of the carrier plate. As the fixing plate moves down, the pressure block elastically compresses the elastic element on its top side, and the pressure block moves upward into the fixing hole. In this way, when the pressure block is used to cover the workpiece in the positioning groove, the pressure block can elastically press against the carrier plate. The pressure block, which can move up and down elastically, can provide upward movement and avoidance for the protruding parts on the carrier plate or the unassembled workpiece, thereby better protecting the workpiece and improving the overall versatility.
[0010] As a further improvement to the above technical solution, the cover plate and the fixing plate are detachably connected. The cover plate and the fixing plate can be disassembled and reassembled, thereby facilitating the replacement and maintenance of internal elastic components, pressure blocks, etc., reducing maintenance costs and improving the flexibility of use.
[0011] As a further improvement to the above technical solution, the top outer edge of the carrier plate is provided with a positioning guide angle, and the bottom side of the fixing plate is provided with a positioning rib, which is engaged with the positioning guide angle. When the fixing plate is connected to the top side of the carrier plate, the alignment and engagement of the positioning rib and the positioning guide angle can quickly and accurately connect the fixing plate to the carrier plate, and can improve the sealing between the fixing plate and the carrier plate, reducing plasma leakage.
[0012] As a further improvement to the above technical solution, each of the plurality of pressure blocks has a mounting groove on its top side, and the bottom ends of the plurality of elastic elements can be inserted into the plurality of mounting grooves respectively. When it is necessary to install the elastic element, the elastic element is placed into the mounting groove on the top side of the pressure block. The mounting groove provides a limit for the elastic element, improving the overall assembly efficiency and providing installation space for the elastic element. This reduces the installation space required between the cover plate and the pressure block for the elastic element, making the overall structure more compact.
[0013] As a further improvement to the above technical solution, when the fixing plate abuts against the carrier plate, the pressure block abuts against the carrier plate. This eliminates the gap between the pressure block and the carrier plate, preventing the workpiece located in the positioning groove from moving out between the pressure block and the carrier plate, thus further improving the workpiece positioning effect.
[0014] As a further improvement to the above technical solution, multiple air pipes are arranged horizontally at intervals inside the base, and multiple air channels are formed within each of the multiple air pipes. Multiple air outlets are provided along the length of each of the multiple air pipes on their top sides. The air intake assembly can introduce air into each of the multiple air channels. When plasma cleaning is required, gas can be introduced into the air channels of the multiple air pipes from the air intake assembly. Since the multiple air pipes are arranged horizontally at intervals and have multiple air outlets on their top sides, plasma can be introduced into the ventilation groove from multiple air outlets, and then enter the multiple through holes on the bottom side of the carrier plate. This improves the uniformity of plasma intake, thereby enhancing the effect of simultaneously cleaning multiple workpieces.
[0015] As a further improvement to the above technical solution, the air intake assembly includes an adapter plate and multiple air nozzles connected to the adapter plate. The adapter plate is connected to the side wall of the base, and the multiple air nozzles are respectively connected to multiple air passages. The adapter plate is used to connect and fix the multiple air nozzles. In use, the multiple air nozzles are connected to an external plasma supply device, so that plasma is input from the multiple air nozzles into the air passages of the multiple air tubes, thereby improving the uniformity and efficiency of air intake.
[0016] As a further improvement to the above technical solution, a sealing gasket is connected between the adapter plate and the base. Using the sealing gasket can better fill the assembly gap between the adapter plate and the base, reducing leakage from between the adapter plate and the base during air intake, and thus helping to reduce overall operating energy consumption.
[0017] As a further improvement to the above technical solution, air intake components are respectively provided on both sides of the base, and the two air intake components can respectively introduce air into both ends of the multiple air channels. When the air intake components on both sides of the base are simultaneously connected to an external plasma supply device, air is simultaneously introduced from the air intake components on both sides into both ends of the air channels during operation, effectively improving the uniformity and efficiency of air intake.

[0029] Reference Figures 1 to 5 A plasma cleaning device includes a base 100, a carrier plate 200, and a molding die 300. The base 100 has an air passage 110 inside, and an air intake component 120 for air intake into the air passage 110 is provided on at least one side of the base 100. An air outlet 131 communicating with the air passage 110 is provided on the top side of the base 100. The carrier plate 200 is connected to the top side of the base 100. A ventilation groove 210 is provided on the bottom side of the carrier plate 200. The air outlet 131 communicates with the ventilation groove 210. A plurality of positioning grooves 220 are provided on the top side of the carrier plate 200. The bottom of the plurality of positioning grooves 220 is provided with a through hole 230 communicating with the ventilation groove 210. The molding die 300 is connected to the top side of the carrier plate 200 and can cover the plurality of positioning grooves 220.
[0030] As described above, the workpiece to be cleaned (e.g., but not limited to, a lens) is placed in the positioning groove 220 of the carrier plate 200, and the positioning groove 220 is used to limit the workpiece. Then, the carrier plate 200 is moved to the top side of the base 100. At this time, the air outlet 131 on the top side of the base 100 is connected to the ventilation groove 210 on the bottom side of the carrier plate 200. The mold 300 is connected to the top side of the carrier plate 200, covering the multiple positioning grooves 220 on the top side of the carrier plate 200. The air inlet assembly 120 is connected to the external plasma supply equipment, and plasma is input into the air passage 110 through the air inlet assembly 120. The plasma is output from the air outlet 131 to the ventilation groove 210. Within the air vent 210, the air vent 210 provides space for plasma to flow, allowing the plasma to flow to the corresponding through hole 230 position and enter the through hole 230 at the bottom of multiple positioning grooves 220 to clean the workpiece. The active particles in the plasma react chemically or physically with the contaminants on the workpiece surface, thereby cleaning the surface. During this process, the pressure mold 300 can limit the workpiece to prevent it from moving out of the positioning groove 220. Therefore, this invention can clean multiple workpieces simultaneously, greatly improving the workpiece cleaning efficiency and effectively removing contaminants from their surfaces, thus improving the cleaning quality.
[0031] In an external plasma supply device, one or more process gases, such as argon, oxygen, and nitrogen, are injected. By applying radio frequency energy or DC voltage, an electric field is generated in a low-pressure environment, causing the gas molecules to ionize and form plasma. Under the influence of the electric field, the gas molecules decompose into positively charged ions, negatively charged electrons, and other active particles, such as free radicals and ion clusters. These active particles have high chemical reactivity. The active particles in the plasma react chemically with contaminants on the surface of the object to be treated, such as organic matter, oxide layers, and particles, or remove contaminants through physical impact. These reactions can decompose organic contaminants and oxidize or reduce inorganic contaminants, thereby achieving the purpose of cleaning the surface of workpieces such as lenses.
[0032] When the workpiece is relatively small, such as when the bottom surface of the mold 300 is flat, pressing the mold 300 directly onto the top side of the carrier plate 200 will effectively cover the workpiece. However, for workpieces with a relatively large height, corresponding recesses need to be provided on the bottom side of the mold 300 to avoid protruding workpieces. Specifically, pressure blocks 310 are provided in the mold 300 at positions corresponding to multiple positioning grooves 220, and clearance grooves 311 are provided on the bottom sides of the multiple pressure blocks 310. The multiple pressure blocks 310 abut against the top side of the carrier plate 200. When the mold 300 is connected to the top side of the carrier plate 200, the multiple pressure blocks 310 in the mold 300 abut against the top side of the carrier plate 200. At this time, the workpieces in the multiple positioning grooves 220 on the carrier plate 200 are located in the clearance grooves 311 of the multiple pressure blocks 310, and the clearance grooves 311 avoid the position of the workpiece. This is especially suitable for limiting the height of workpieces.
[0033] As a specific structural embodiment of the compression mold 300, the compression mold 300 includes a cover plate 320 and a fixing plate 330. The top side of the fixing plate 330 is provided with a plurality of fixing holes 331. A plurality of pressing blocks 310 are disposed between the cover plate 320 and the fixing plate 330, and the plurality of pressing blocks 310 are respectively movably connected to the plurality of fixing holes 331. The cover plate 320 is connected to the top side of the fixing plate 330, and the fixing plate 330 is connected to the top side of the carrier plate 200. Elastic members 340 are respectively provided between the cover plate 320 and the plurality of pressing blocks 310. The plurality of elastic members 340 can respectively press the plurality of pressing blocks 310 down into the plurality of fixing holes 331, so that the plurality of pressing blocks 310 protrude from the plurality of fixing holes 331. The pressure block 310 is inserted into the fixing hole 331 on the top side of the fixing plate 330 and can move up and down within the fixing hole 331. The cover plate 320 is connected to the top side of the fixing plate 330. The cover plate 320 presses down on the pressure block 310 through the elastic element 340, so that the pressure block 310 is at the bottom of the stroke position. At this time, the pressure block 310 protrudes downward from the fixing hole 331. When the fixing plate 330 is connected to the top side of the carrier plate 200, the bottom side of the pressure block 310 first abuts against the top side of the carrier plate 200. As the fixing plate 330 moves down, the pressure block 310 elastically compresses the elastic element 340 on its top side and the pressure block 310 moves upward into the fixing hole 331. Thus, when the pressure block 310 is used to cover the workpiece in the positioning groove 220, the pressure block 310 can elastically press against the carrier plate 200. The pressure block 310, which can move up and down elastically, can closely adhere to the carrier plate 200 or the workpiece.
[0034] After prolonged use, the internal elastic components 340 and other parts of the molding die 300 are prone to damage, requiring timely replacement and maintenance of the internal structure. Therefore, to reduce overall maintenance costs, in this embodiment, the cover plate 320 and the fixing plate 330 are detachably connected. For example, the cover plate 320 and the fixing plate 330 can be connected to each other by snap-fit, or by screws. The cover plate 320 and the fixing plate 330 can be disassembled and assembled, thereby facilitating the replacement and maintenance of the internal elastic components 340, pressure blocks 310, etc., reducing maintenance costs and improving the flexibility of use.
[0035] To better align and connect the fixing plate 330 and the carrier plate 200, in this embodiment, a positioning guide angle 250 is provided on the outer edge of the top side of the carrier plate 200. The positioning guide angle 250 can be a concave corner on the outer edge of the top side of the carrier plate 200. A positioning rib 332 is provided on the bottom side of the fixing plate 330, and the positioning rib 332 is fitted into the positioning guide angle 250. In practical applications, the positioning guide angle 250 is provided around the entire outer edge of the top side of the carrier plate 200, and the positioning rib 332 is also provided around the entire bottom side of the fixing plate 330, thereby strengthening the fit between the positioning rib 332 and the positioning guide angle 250. When the fixing plate 330 is connected to the top side of the carrier plate 200, the alignment and fit of the positioning rib 332 and the positioning guide angle 250 can quickly and accurately connect the fixing plate 330 to the carrier plate 200, and improve the sealing between the fixing plate 330 and the carrier plate 200.
[0036] The elastic element 340 is mainly used to provide elastic deformation in the vertical direction. It has various structural forms, such as rubber or a spring. To facilitate the insertion of the elastic element 340 into the top side of the pressure block 310, in this embodiment, each of the pressure blocks 310 has a mounting groove 312 on its top side. The bottom ends of the multiple elastic elements 340 can be inserted into the mounting grooves 312 respectively. When the elastic element 340 needs to be inserted, it is placed into the mounting groove 312 on the top side of the pressure block 310. The mounting groove 312 provides a limiting position for the elastic element 340, improving overall assembly efficiency and providing installation space for the elastic element 340. This reduces the installation space required between the cover plate 320 and the pressure block 310 for the elastic element 340, resulting in a more compact overall structure.
[0037] In the above embodiments, when the fixing plate 330 abuts against the carrier plate 200, the pressure block 310 and the carrier plate 200 may not abut against each other. In this case, the clearance groove 311 on the bottom side of the pressure block 310 mainly provides a limit for the workpiece. However, in this embodiment, when the fixing plate 330 abuts against the carrier plate 200, the pressure block 310 abuts against the carrier plate 200. This eliminates the gap between the pressure block 310 and the carrier plate 200, so that the workpiece located in the positioning groove 220 will not move out from between the pressure block 310 and the carrier plate 200, further improving the positioning effect of the workpiece, and forming an independent cleaning area for each workpiece.
[0038] In the above embodiment, only one air channel 110 can be provided in the base 100. However, when there are many positioning slots 220, the through holes 230 that are far from the air channel 110 are prone to slow or insufficient plasma filling. In order to better ensure the plasma cleaning effect, in this embodiment, multiple air pipes 130 are arranged at intervals along the horizontal direction in the base 100. Multiple air channels 110 are formed in the multiple air pipes 130 respectively. Multiple air outlets 131 are provided on the top side of the multiple air pipes 130 along their length direction. The air intake component 120 can respectively intake air into the multiple air channels 110. When plasma cleaning is required, gas can be introduced from the air intake assembly 120 into the air passages 110 of multiple air pipes 130. Since multiple air pipes 130 are arranged at intervals in the horizontal direction and multiple air outlets 131 are provided on the top side of the air pipes 130, plasma can be introduced into the ventilation groove 210 from the air outlets 131 at multiple positions, and then enter into the multiple through holes 230 on the bottom side of the carrier plate 200. This improves the uniformity of plasma intake, thereby improving the effect of cleaning multiple workpieces at the same time.
[0039] The air intake assembly 120 is used to connect to the plasma supply device of the external device and to input plasma into the multiple air passages 110. In the air intake assembly 120, only one connection point is provided for connecting to the plasma supply device of the external device. In order to improve the air intake efficiency, in this embodiment, the air intake assembly 120 includes a converter plate 121 and multiple air nozzles 122 connected to the converter plate 121. The converter plate 121 is connected to the side wall of the base 100. The multiple air nozzles 122 are respectively connected to the multiple air passages 110. Naturally, the converter plate 121 is provided with openings corresponding to the positions of the multiple air nozzles 122. The multiple air nozzles 122 correspond to the multiple openings respectively, and the multiple air nozzles 122 input plasma into the corresponding air passages 110 from the multiple openings respectively. The adapter plate 121 is used to connect and fix multiple air nozzles 122. In use, the multiple air nozzles 122 are connected to the plasma supply equipment of the external device, so that plasma is input from the multiple air nozzles 122 into the air passages 110 of the multiple air tubes 130 respectively, thereby improving the uniformity and efficiency of air intake.
[0040] Furthermore, a sealing gasket 123 is connected between the adapter plate 121 and the base 100. The sealing gasket 123 better fills the assembly gap between the adapter plate 121 and the base 100, reducing leakage during air intake and thus helping to reduce overall energy consumption. In practical applications, the adapter plate 121 and the base 100 are detachably connected. For example, screws are used to pass through the adapter plate 121 and connect it to the base 100, thereby locking the adapter plate 121 to the base 100. During this process, the sealing gasket 123 is placed between the adapter plate 121 and the base 100, and the screw passes through the adapter plate 121 and the sealing gasket 123 in sequence before connecting to the base 100, thereby locking the sealing gasket 123 to the base 100.
[0041] The base 100 may have an air intake assembly 120 on only one side. When the air intake assembly 120 inputs plasma into one end of the air passage 110, the plasma continuously exits from the air outlet 131 on the top side as it flows along the air passage 110. At this time, the plasma content inside the end of the air passage 110 that is farther away from the air intake assembly 120 is relatively low, and uneven distribution is likely to occur when filling the ventilation groove 210. In order to further improve the uniformity of plasma filling the ventilation groove 210, in this embodiment, air intake assemblies 120 are respectively provided on both sides of the base 100, and the two air intake assemblies 120 can respectively intake air into both ends of multiple air passages 110. When the air intake assemblies 120 on both sides of the base 100 are simultaneously connected to an external plasma supply device, during operation, air is simultaneously intakeed from both sides of the air intake assembly 120 into both ends of the air passage 110, effectively improving the uniformity and efficiency of air intake.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
