Description

Technical Field

[0001] This invention relates to the field of glass dust removal technology, specifically to a glass surface cleaning and dust removal device. Background Technology

[0002] In the production of high-precision glass such as electronic glass, optical glass, and photovoltaic glass, the cleanliness of the glass surface directly determines the quality of downstream products. For example, when electronic glass is used in display manufacturing, micron-sized dust residue on the surface can cause pixel abnormalities; impurities on the surface of photovoltaic glass can affect light absorption efficiency and reduce power generation. Therefore, the glass production process requires strict dust removal treatment and must be adapted to the production needs of glass of different thicknesses, while meeting the environmental requirements of cleanrooms for "zero dust diffusion."

[0003] Current glass dust removal equipment primarily operates through a combination of mechanical sweeping and negative pressure suction: glass is conveyed at a uniform speed to the dust removal area via a transport track, where brushes or rollers contact the glass surface to clean impurities, and then a negative pressure suction device removes the stirred-up dust. Some equipment incorporates a dust-proof structure to reduce dust escape. To ensure effective dust removal, the equipment must achieve three core functions: tight contact between the dust removal components and the glass surface, height adjustment to accommodate glass of varying thicknesses, and zero deviation during the cleaning process. Simultaneously, it must prevent glass breakage due to excessive contact pressure (especially for ultra-thin electronic glass). These requirements place high demands on the equipment's structural design and integrated control system. Summary of the Invention

[0004] The present invention provides a glass surface cleaning and dust removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass surface cleaning and dust removal device, comprising an operating table, wherein the operating table provides electrical control support for the entire device and is used to control the start and stop of each actuator and the adjustment of operating parameters; a side platform is fixedly installed on the operating table, and a suction pipe is installed through the center of the side platform; one end of the suction pipe extends to the glass cleaning area to absorb floating dust generated during the cleaning process, and the other end is sealed to an air extraction device to form a negative pressure suction channel;

[0006] The frame is a door frame structure, with its two ends fixedly connected to the side connecting platform, and the inner side wall of the frame is inclinedly fixed with a guide plate; the high end of the guide plate faces the glass cleaning area, and the low end extends to the outside of the frame, which is used to discharge large particles of impurities separated during the cleaning process to the outside to avoid particle accumulation.

[0007] A dustproof board is fixedly installed on the outside of the frame, and the dustproof board encloses a semi-enclosed space to block most of the dust and keep it inside the frame, preventing the dust from spreading to the external environment.

[0008] The No. 1 dust removal mechanism is located inside the crossbeam of the frame and is used to perform preliminary dust removal and cleaning on the glass surface.

[0009] The first dust removal mechanism includes a column, which is inserted vertically through the bottom crossbeam of the frame, and a dust removal brush is fixedly connected to the bottom end of the column.

[0010] The sidewall of the column has several notches, which are arranged in a linear array along the height of the column, and the opening size of the notches increases from top to bottom. A No. 3 plate is fitted on the outside of the notch, and the No. 3 plate is used to adjust the extension length of the column.

[0011] Preferably, the platform has a groove inside, a first elastic telescopic rod is fixedly installed at the top of the inner cavity of the groove, a first plate is fixedly connected to the bottom end of the first elastic telescopic rod, the first plate is slidably adapted to the inside of the groove, and the bottom of the first plate is fixedly connected to the column.

[0012] Both ends of the No. 1 plate are symmetrically connected with long strips, which slide and fit inside the groove to enhance the stability of the No. 1 plate during sliding and prevent the column from shifting.

[0013] Preferably, a connecting strip is fixedly connected to the top of the first plate, and the connecting strip extends upward;

[0014] The second plate is fixedly installed inside the frame, and the second elastic telescopic rod is fixedly connected to the outside of the second plate. The end of the second elastic telescopic rod away from the second plate is fixedly connected to the third plate, which is used to drive the third plate to engage or disengage from the notch.

[0015] Preferably, the frame is equipped with a second dust removal mechanism, which includes a servo motor. The servo motor is slidably adapted to the inside of the frame. The output end of the servo motor is connected to a first shaft through a coupling. A first dust removal roller is fixedly connected to the outside of the first shaft.

[0016] The surface of the first dust removal roller is covered with microfiber cloth, which is used to perform secondary dust removal on the glass surface and remove the fine dust remaining after the initial cleaning.

[0017] Preferably, the end of the first axis away from the servo motor is slidably adapted to the frame via a bearing assembly, wherein the bearing assembly consists of a bearing and an external plate. The inner ring of the bearing is pressed and adapted to the first axis, while the outer ring of the bearing is connected to the external plate. At the same time, the external plate is slidably adapted to the inside of the frame to provide rotational support for the first axis and move synchronously with the servo motor.

[0018] Preferably, a roller support is connected to the outer side of the first shaft via a bearing, the top of the roller support is fixedly connected to the connecting strip, and a fixed pulley assembly is slidably adapted to the outer side of the connecting strip. The fixed pulley assembly is fixedly installed on the top of the inner cavity of the frame, and the fixed pulley assembly consists of a fixed pulley and a support.

[0019] Preferably, a third elastic telescopic rod is fixedly connected to the top of the roller support, and a hydraulic rod is fixedly installed at the top of the third elastic telescopic rod. The hydraulic rod is fixedly installed on the top of the frame, and the first dust removal roller is indirectly driven to move downward through the hydraulic rod, so that the connecting bar drives the column and the dust removal brush to move upward with the fixed pulley assembly as the fulcrum.

[0020] Preferably, a sleeve rod is connected to the outer side of the output end of the hydraulic rod via a connector. The end of the sleeve rod away from the hydraulic rod is connected to a second shaft via a bearing. A first gear is fixedly connected to the outer side of the second shaft. An internal and external gear chain meshes with the outer side of the first gear.

[0021] Preferably, the first gear has discs symmetrically arranged at both ends, and the discs are used to limit the internal and external gear chains and the first gear. The second shaft has second dust removal rollers symmetrically connected to both ends.

[0022] Preferably, a shaft support is fixedly installed on the top of the roller support, and a second gear is rotatably installed inside the shaft support via a shaft. The top of the second gear meshes with the bottom of the inner and outer gear chains for synchronous rotation with the inner and outer gear chains, thereby assisting in adjusting the movement trajectory of the roller support and ensuring the dust removal accuracy of the first dust removal roller.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The pre-pressure design ensures a tight fit between the dust removal brush and the glass surface, preventing dust from being missed due to contact gaps. A guiding structure further prevents brush misalignment, guaranteeing the accuracy of subsequent cleaning operations. Furthermore, the pre-constructed negative pressure suction channel and semi-enclosed dust-proof space form a dust barrier before cleaning begins, reducing dust diffusion at the source and ensuring a clean production environment in the cleanroom, minimizing the impact of dust on the quality of subsequent glass processing.

[0025] 2. In the initial dust removal stage, the combined effect of mechanical sweeping, negative pressure dust collection and directional dust removal achieves efficient treatment of pollutants of different forms on the glass surface: large particles of impurities are directed out and collected in a concentrated manner through the guiding structure, effectively avoiding secondary pollution caused by the accumulation of impurities in the cleaning area; floating dust is quickly removed by negative pressure, and with the help of the dust isolation structure to prevent its dissipation, the dust concentration in the workshop air is greatly reduced.

[0026] 3. The secondary enhanced dust removal stage uses a flexible contact design to precisely control the contact pressure between the dust removal roller and the glass surface within a safe range. This ensures that the microfiber cloth adheres tightly to the glass to adsorb fine dust, while also preventing scratches on fragile glass due to excessive pressure. This perfectly meets the cleaning needs of fragile glass such as electronic glass and optical glass.

[0027] 4. The second dust removal roller provides supplementary cleaning to the glass edges and corners. Combined with a stable transmission and limiting structure, this ensures thorough cleaning without any blind spots and minimizes the risk of chain slippage or misalignment during transmission, further enhancing dust removal accuracy. Furthermore, the vibration generated as the column moves upwards dislodges impurities adhering to the dust removal brush surface, preventing "dust-laden cleaning" from affecting subsequent operations and resulting in superior overall cleaning performance, meeting the needs of scenarios with extremely high requirements for glass surface cleanliness.

[0047] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] Please see Figures 1 to 10 The present invention provides a technical solution:

[0049] Example 1: Initialization and adaptation stage of glass dust removal.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6and Figure 7 As shown, for the glass to be cleaned, the operator controls the second elastic telescopic rod 68 inside the frame 3 via the control panel 1. This control primarily manages the retraction of the second elastic telescopic rod 68. One end of the second elastic telescopic rod 68 is fixedly connected to the second plate 67 welded to the inner wall of the frame 3, and the other end is welded to the third plate 69. Simultaneously, the retraction causes the third plate 69 to disengage from the notch 601 on the side wall of the column 65. The column 65 is vertically inserted into the bottom crossbeam of the frame 3, with a nylon dust removal brush 66 bolted to its bottom end. The side wall has notches 601 with increasing opening sizes from top to bottom along the height direction. Adjusting the extension length of the column 65 allows the distance between the bottom of the dust removal brush 66 and the glass conveying surface to match the required glass thickness. Under the action of elastic force, the second elastic telescopic rod 68 pushes the third plate 69 into the corresponding notch 601, locking the column 65 in place. Meanwhile, the bottom end of the first elastic telescopic rod 62 fixed to the top of the inner tank 61 of the frame 3 is fixed to the first plate 63 that slides inside the tank 61. The bottom of the first plate 63 is welded to the top of the column 65. At this time, the first elastic telescopic rod 62 naturally extends and applies downward pre-pressure to the column 65 through the first plate 63 to ensure that the dust removal brush 66 can fit tightly against the glass surface. The long strips 64 symmetrically welded at both ends of the first plate 63 slide along the inner wall of the tank 61 to prevent the column 65 from shifting during adjustment.

[0051] Through the linkage structure of "No. 2 elastic telescopic rod 68 - No. 3 plate 69 - notch 601", the dust removal brush 66 can be precisely adapted to glass of different thicknesses to meet the needs of high-precision production; the pre-pressure design of No. 1 elastic telescopic rod 62 and the guiding effect of the long strip plate 64 ensure that the dust removal brush 66 fits the glass stably and without deviation; the pre-constructed negative pressure dust suction channel and semi-enclosed dust isolation space reduce dust diffusion from the source and meet the production requirements of cleanroom.

[0052] Example 2: Preliminary dust removal operation stage for glass.

[0053] like Figure 1 , Figure 2 and Figure 4As shown, the control panel 1 controls the start of the external glass conveying track, which uniformly transports the glass to be cleaned to the cleaning area below the frame 3 at a speed of 0.3 m / s. After the glass enters the semi-enclosed space enclosed by the dustproof plate 5, the dust removal brush 66, under the pre-pressure of the first elastic telescopic rod 62, adheres tightly to the glass surface and performs lateral sweeping as the glass moves, separating large particles such as glass shards, dust particles, and floating dust. The separated large particles slide down to the inclined guide plate 4 on the inner wall of the frame 3 under the action of gravity, slide out of the frame 3 along the inclined surface of the guide plate 4, and fall into the pre-set waste collection box below, avoiding the accumulation of impurities in the cleaning area and causing secondary pollution. At the same time, the control panel 1 maintains the operation of the exhaust equipment, and the suction pipe 8 sucks in the floating dust generated during cleaning through negative pressure and discharges it through the suction channel. The dustproof plate 5 further blocks some of the escaped dust, ensuring that most of the dust is confined in the semi-enclosed space, ensuring the cleanliness of the cleanroom environment.

[0054] Example 3: Secondary glass strengthening and dust removal stage.

[0055] like Figure 8 , Figure 9 and Figure 10 As shown, the glass after initial dust removal is conveyed in the reverse direction. The operating platform 1 switches to the secondary dust removal mode, which activates the hydraulic rod 76 connected to the top of the control frame 3 via fasteners. The output end of the hydraulic rod 76 is fixed to the top of the third elastic telescopic rod 75. The bottom end of the third elastic telescopic rod 75 is welded to the top of the roller support 73. The roller support 73 is connected to the first shaft 77 via a bearing. One end of the first shaft 77 is connected to the output end of the servo motor 71 sliding inside the frame 3 via a coupling. The other end is connected to a bearing assembly consisting of a bearing and an external plate. The inner ring of the bearing assembly is pressed and fitted to the first shaft 77, and the outer ring of the bearing is welded to the external plate. The external plate slides up and down along the guide rail of the frame 3 for support. The first dust removal roller 72, with an interference fit roller surface wrapped with microfiber cloth, is located on the outside of the first shaft 77. At this time, the output end of the hydraulic rod 76 extends downward, pushing the No. 3 elastic telescopic rod 75 to drive the roller support 73 to move downward in the vertical direction. The roller support 73 simultaneously drives the No. 1 shaft 77 and the No. 1 dust removal roller 72 to move downward until the ultra-fine fiber cloth on the surface of the No. 1 dust removal roller 72 is in close contact with the glass surface and the contact pressure is controlled at 3N to avoid damaging the glass.

[0056] During the downward movement of the roller support 73, the connecting strip 60 welded to the top of the first plate 63 moves synchronously. The connecting strip 60 slides along the fixed pulley assembly 74 fixed to the top of the inner cavity of the frame 3, i.e., the groove inside the fixed pulley. The fixed pulley assembly 74 provides guidance for the connecting strip 60, ensuring that the roller support 73 moves downward smoothly. The connecting strip 60 pulls the first plate 63 upward along the groove 61. The first plate 63 compresses the first elastic telescopic rod 62 and drives the column 65 and the dust removal brush 66 to move upward synchronously, so that the dust removal brush 66 temporarily detaches from the glass surface to avoid interference with the first dust removal roller 72. The upward movement of the column 65... During the process, plate 69 slides relative to the notch 601 and compresses the elastic telescopic rod 68. When plate 69 moves out of the notch 601 and slides along the outer surface of the column 65 until it reaches the second notch 601, plate 69 quickly impacts the second notch 601 under the elastic force of the elastic telescopic rod 68 and vibrates, thereby shaking off the impurities and dust adhering to the surface of the dust removal brush 66. In addition, the size of the notch 601 increases from top to bottom. Therefore, as the column 65 continues to move upward, the vibration force generated by plate 69 on the column 65 will gradually increase.

[0057] Subsequently, the control panel 1 starts the servo motor 71, which drives the first shaft 77 to rotate clockwise at a speed of 250 r / min through the coupling. The first shaft 77 drives the first dust removal roller 72 to rotate synchronously. The microfiber cloth adsorbs the fine dust remaining on the glass surface through friction, realizing secondary fine dust removal. The bearing assembly at the other end of the first shaft 77 moves synchronously along the guide rail of the frame 3 with the servo motor 71, providing stable rotation support for the first shaft 77, ensuring the rotation accuracy of the first dust removal roller 72, and avoiding uneven cleaning due to shaft shaking.

[0058] Meanwhile, the outer side of the output end of the hydraulic rod 76 is connected to the sleeve rod 78 welded by the connector. The end of the sleeve rod 78 away from the hydraulic rod 76 is connected to the second shaft 79 through a bearing. The outer side of the second shaft 79 is interference-fitted with the first gear 70 and the symmetrically distributed second dust removal roller 702. The hydraulic rod 76 continues to extend downward, driving the second shaft 79 to move downward synchronously through the sleeve rod 78. The first gear 70 on the outer side of the second shaft 79 meshes with the internal and external gear chains 701, driving the second shaft 79 and the second dust removal roller 702 to move downward until the second dust removal roller 702 is in contact with the glass surface. At this time, the third elastic telescopic rod 75 is in a compressed state due to the fixed position of the roller support 73, providing buffer pressure and preventing the dust removal roller from excessively squeezing the glass and causing damage. Inside the shaft support 703 welded to the top of the roller support 73, the No. 2 gear 704, which is rotatably mounted on the shaft, meshes with the bottom of the inner and outer gear chains 701. It rotates synchronously with the inner and outer gear chains 701, driving the No. 2 dust removal roller 702 to rotate at the same speed as the No. 1 dust removal roller 72, thus supplementing the cleaning of the glass edge and areas not covered by the No. 1 dust removal roller 72. The diameter of the discs symmetrically arranged at both ends of the No. 1 gear 70 is larger than the tip circle of the gear teeth, which limits the inner and outer gear chains 701 and the No. 1 gear 70, preventing chain derailment or deviation during transmission and ensuring cleaning stability.

[0059] The linkage structure of "hydraulic rod 76 - No. 3 elastic telescopic rod 75 - roller support 73" enables flexible contact between the No. 1 dust removal roller 72 and the glass surface to buffer pressure and avoid damage, which is suitable for the fragile characteristics of glass. The high adsorption of microfiber cloth combined with the rotation cleaning of the No. 1 dust removal roller 72 effectively removes fine dust and meets the high-precision dust removal requirements of glass. The edge supplementary cleaning of the No. 2 dust removal roller 702 and the transmission limit design of "gear - internal and external toothed chain" ensure that there are no dead corners in cleaning and stable operation, further improving the dust removal accuracy.

[0060] The working principle of this invention is as follows: Before the device is started, initialization preparation is completed to adapt to the cleaning needs of glass of different thicknesses. The dust suction pipe 8 on the control side of the operating table 1 is connected to the air extraction equipment to build a negative pressure dust suction channel in advance; the semi-enclosed space formed by the dust isolation plate 5 is in a ready-to-use state to prepare for subsequent blocking of dust diffusion. For the first dust removal mechanism 6, the second elastic telescopic rod 68 in the frame 3 drives the third plate 69 to embed into the notch 601 on the side wall of the column 65. By selecting notches 601 of different heights, and with the opening size of the notches 601 increasing from top to bottom, different extension length requirements are met, and the initial height of the dust removal brush 66 at the bottom of the column 65 is adjusted to ensure that the dust removal brush 66 can fit against the glass surface to be cleaned. At the same time, the first elastic telescopic rod 62 applies downward pre-pressure to the column 65 through the first plate 63 to enhance the contact stability between the dust removal brush 66 and the glass surface. The long strips 64 at both ends of the first plate 63 slide along the groove 61 to prevent the column 65 from shifting during adjustment or cleaning.

[0061] In the initial dust removal stage, the device removes most of the dust and impurities from the glass surface through the first dust removal mechanism 6. The operating platform 1 controls the glass conveyor to the cleaning area below the support platform 3. At this time, the dust removal brush 66, under the pre-pressure of the first elastic telescopic rod 62, adheres tightly to the glass surface. As the glass moves or the support platform moves the dust removal mechanism, the dust removal brush 66 performs a horizontal sweep of the glass surface, separating large particles of impurities and floating dust from the glass surface. The separated large particles of impurities slide down to the guide plate 4 under gravity, extending along the inclined surface of the guide plate 4 from the high end towards the cleaning area to the low end, and are discharged outwards to prevent impurities from accumulating in the cleaning area. Simultaneously, the operating platform 1 activates the suction equipment, and the suction pipe 8 uses negative pressure to suck in the floating dust generated during cleaning, which is then discharged through the suction channel, reducing dust residue in the air.

[0062] After initial dust removal, the device switches to a secondary enhanced dust removal mode, using the second dust removal mechanism 7 to remove residual fine dust from the glass surface. The control panel 1 activates the hydraulic rod 76, extending its output end downwards to push the third elastic telescopic rod 75, causing the roller support 73 to move downwards. The roller support 73 then moves the first shaft 77 and the outer first dust removal roller 72 downwards synchronously until the microfiber cloth on the surface of the first dust removal roller 72 adheres to the glass surface. During this process, the roller support 73 pulls the first plate 63 via the connecting strip 60. The fixed pulley assembly 74 guides the movement of the connecting strip 60, ensuring that the roller support 73 and the column 65 move synchronously and smoothly. The first plate 63 compresses the first elastic telescopic rod 62 and moves the column 65 upwards, temporarily detaching the dust removal brush 66 from the glass surface to avoid interference with the first dust removal roller 72. Subsequently, the servo motor 71 starts and drives the first shaft 77 to rotate through the coupling. The first shaft 77 drives the first dust removal roller 72 to rotate. The microfiber cloth adsorbs the fine dust on the glass surface through friction, achieving secondary cleaning. The bearing assembly at the end of the first shaft 77 away from the servo motor 71 consists of a bearing and an external plate and moves synchronously with the servo motor 71, providing stable rotational support for the first shaft 77 and ensuring the rotational accuracy of the dust removal roller.

[0063] During the secondary dust removal process, the second dust removal mechanism 7 further optimizes the cleaning trajectory through the transmission components, improving the uniformity of dust removal. As the hydraulic rod 76 extends downwards, the sleeve rod 78 at the output end of the hydraulic rod 76 drives the second shaft 79 to move downwards synchronously. The first gear 70 on the outer side of the second shaft 79 meshes with the inner and outer gear chains 701. At this time, the second shaft 79 and the second dust removal rollers 702 at both ends move downwards together. The second dust removal rollers 702 assist in cleaning the glass edges or areas not covered by the first dust removal roller 72. Simultaneously, the first dust removal roller 72 is pressed tightly against the glass surface, and the third elastic telescopic rod 75 is in a compressed state. Then, the second gear 704 inside the top shaft support 703 of the roller support 73 meshes with the bottom of the inner and outer gear chains 701, rotating synchronously with the inner and outer gear chains 701, thereby driving the second dust removal roller 702 to rotate synchronously. This prevents the first dust removal roller 72 from shifting, ensuring the accuracy of dust removal. The discs at both ends of the first gear 70 limit the internal and external gear chains 701 and the first gear 70 to prevent chain slippage or deviation during transmission.

[0064] After cleaning is completed, the device enters the reset phase to prepare for the next cleaning. Control panel 1 retracts hydraulic rod 76, which moves elastic telescopic rod 75 and roller support 73 upwards, disengaging dust removal roller 72 from the glass surface. Roller support 73 releases tension on plate 63 via connecting strip 60, resetting elastic telescopic rod 62 and pushing column 65 downwards. Simultaneously, with the operator's cooperation, dust removal brush 66 returns to its initial position. Servo motor 71 stops operating, and shaft 77 and dust removal roller 72 stop rotating. The exhaust system is shut down, and suction pipe 8 stops suction. If cleaning components such as microfiber cloth need replacement, plate 69 can be disengaged from notch 601 by adjusting elastic telescopic rod 68, and column 65 or dust removal roller 72 can be disassembled for maintenance. The entire device returns to its initial standby state.

[0065] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
