Description

Technical Field

[0001] This invention relates to the field of tempered glass film production technology, and in particular to an integrated oiling machine for flat tempered glass films. Background Technology

[0002] Tempered glass screen protector coating machines are automated devices specifically designed to uniformly coat the surface of tempered glass protective films (tempered glass films) with an oleophobic layer (anti-fingerprint oil). To meet the drying and curing requirements of the tempered glass film after coating, existing tempered glass screen protector coating machines use a mesh belt structure for their conveyor belts. The porous nature of the conveyor belts facilitates UV light penetration and hot air circulation, thereby enabling efficient curing of the tempered glass film. However, during the process of spraying oil onto the tempered glass film, the high-speed oil mist sprayed out passes through the gaps between adjacent tempered glass films and diffuses on the back side of the tempered glass film. This diffused oil mist adheres to the OCA optical adhesive layer on the back of the tempered glass film, causing a decrease in the surface energy of the adhesive layer and a reduction in adhesion. Ultimately, this results in defects such as bubbles and edge lifting when the tempered glass film is bonded to the screen, reducing the quality of the produced tempered glass film.

[0003] Furthermore, since the back of the tempered glass film is directly attached to the upper side of the conveyor belt, some of the sprayed oil adheres to the conveyor belt during the oiling process. The oil adhering to the conveyor belt can easily seep from between the conveyor belt and the tempered glass film into the back of the tempered glass film, resulting in a decrease in the adhesiveness of the chemical adhesive layer on the back of the tempered glass film. Summary of the Invention

[0004] To overcome the shortcomings of existing tempered glass film coating machines, where the conveyor belt facilitates curing but oil mist can penetrate the conveyor belt and contaminate the OCA adhesive layer on the back of the tempered glass film during spraying, leading to decreased adhesion, bonding bubbles, and edge curling, thus reducing the quality of the tempered glass film, this invention provides an integrated coating machine for flat tempered glass films.

[0007] As a preferred embodiment of the present invention, the moving part includes a slide rail two and an electric slider two; the slide rail two is fixedly connected to the enclosed cover; the electric slider two is slidably connected to the slide rail two; the electric slider two is connected to an atomizing nozzle for spraying anti-fingerprint oil; the atomizing nozzle is connected to an external oil supply device.

[0008] As a preferred embodiment of the present invention, each support rod is provided with a fixing suction cup for fixing the tempered glass film.

[0009] As a preferred embodiment of the present invention, it further includes a recovery component, which includes a scraper and a suction tube; two scrapers are fixedly attached to the outside of the atomizing nozzle for scraping off the oil adhering to the inner wall of the sealed cover; each scraper is in contact with the inner wall of the sealed cover; two suction tubes are fixedly attached to the outside of the sealed cover for sucking up and recovering the anti-fingerprint oil; each suction tube is connected to an external suction device.

[0010] As a preferred embodiment of the present invention, it further includes receiving plates; each scraper is fixedly connected to two receiving plates for receiving dripping oil.

[0011] As a preferred embodiment of the present invention, the inner wall of the enclosure is coated with an oleophobic coating.

[0012] As a preferred embodiment of the present invention, it further includes a support plate and a carrier plate; the housing is provided with a support plate and a carrier plate for supporting the conveyor belt; both the support plate and the carrier plate are in contact with the upper lower side of the conveyor belt; the distance between the right end face of the support plate and the left end face of the carrier plate is equal to the length of the drying zone.

[0013] As a preferred embodiment of the present invention, each support rod is a hollow tube.

[0014] As a preferred embodiment of the present invention, both the upper surface of the support plate and the upper surface of the bearing plate are made into smooth surfaces.

[0015] The beneficial effects are: the present invention achieves the formation of a closed chamber by combining the closed cover and the sealing film with the tempered film, which prevents the oil mist sprayed at high speed from spreading to the surroundings and adhering to other coated or uncoated tempered film surfaces after contacting the tempered film, thus avoiding uneven adhesion of oil mist on the surface of the tempered film. By sealing the membrane, oil mist is prevented from being sprayed onto the upper side of the conveyor belt, and oil is prevented from adhering from between the conveyor belt and the tempered film to the back of the tempered film, thus preventing the adhesive layer on the back of the tempered film from becoming less viscous and ensuring the quality of the tempered film. The receiving plate collects the dripping oil, preventing it from dripping directly onto the tempered glass film below and avoiding splashing and contaminating other tempered glass films. This ensures that the oil recovery operation does not affect the normal oiling process of the tempered glass film, thereby guaranteeing the quality of the finished flat tempered glass film.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 like Figures 1-6 As shown, an integrated oiling machine for flat tempered glass film includes a housing 1 and a conveyor belt 2; the housing 1 is provided with the conveyor belt 2 for conveying; the housing 1 is provided with a drying zone 1001 for drying; a UV lamp is provided in the drying zone 1001. The housing 1 is equipped with two symmetrically arranged telescopic drive components 3, which are electric push rods. The telescopic ends of all telescopic drive components 3 are bolted together to a closed cover 4. The inner wall of the closed cover 4 is set as an inclined surface, which is conducive to guiding the oil and reducing the oil dripping onto the tempered glass film surface. A sealing membrane 5 is set at the bottom of the closed cover 4. Several support rods 2001 are set on the conveyor belt 2. The support rods 2001 are made of hard rubber. Several upturned parts 5001 are set on the sealing membrane 5. The closed cover 4, the sealing membrane 5 and the tempered glass film are combined to form a closed chamber. All the upturned parts 5001 are in contact with the outer side of the tempered glass film. An atomizing nozzle 203 for spraying anti-fingerprint oil is set inside the closed cover 4. The atomizing nozzle 203 can be used to spray the tempered glass film by sliding back and forth using a moving part.

[0020] It also includes a cleaning component, which includes a slide rail 101, an electric slider 102, and a plasma fan 103; the slide rail 101 is fixedly connected to the housing 1; the electric slider 102 is slidably connected to the slide rail 101; and the plasma fan 103 is fixedly connected to the electric slider 102.

[0021] The moving parts include a slide rail 201 and an electric slider 202; the enclosure 4 is fixedly connected to the slide rail 201; the electric slider 202 is slidably connected to the slide rail 201; the electric slider 202 is connected to the atomizing nozzle 203; the atomizing nozzle 203 is connected to the external oil supply equipment.

[0022] Each support rod 2001 is equipped with a fixed suction cup 2002.

[0023] It also includes a recycling component, which includes a scraper 301 and a suction pipe 302; two symmetrically arranged scrapers 301 are fixed to the outside of the atomizing nozzle 203; each scraper 301 is in contact with the inner wall of the enclosure 4; two symmetrically arranged suction pipes 302 are fixed to the outside of the enclosure 4; each suction pipe 302 is connected to an external suction device.

[0024] It also includes a receiving plate 303; two symmetrically arranged receiving plates 303 are fixedly connected to each scraper 301.

[0025] The inner wall of the enclosure 4 is coated with an oleophobic coating, which helps to reduce the adhesion of oil mist on the inner wall of the enclosure 4 and enhances the recycling effect of anti-fingerprint oil.

[0026] During the oiling process for the flat tempered glass film, the external feeding mechanism places the flat tempered glass film onto the support rod 2001 on the conveyor belt 2. The conveyor belt 2 then transports the flat tempered glass film into the housing 1, and the electric slider 102 drives the plasma air bar 103 to slide back and forth on the slide rail 101. When the flat tempered glass film passes under the plasma air bar 103, the high-voltage electric field released by the plasma air bar 103 ionizes the surrounding gas, causing positive ions in the plasma to bombard the surface of the tempered glass film under the acceleration of the electric field, directly stripping away contaminants from the surface of the tempered glass film, thus cleaning the surface to be oiled. As the conveyor belt 2 continues to transport the tempered glass film to the right, when the tempered glass film moves below the sealing cover 4, the conveyor belt 2 stops transporting. Then, the telescopic drive 3 lowers the sealing cover 4 and the sealing membrane 5 until they are in contact with the upper side of the conveyor belt 2, allowing the sealing cover 4 to clean the tempered glass film. The shielding, with the upturned part 5001 adhering to the outer side of the tempered glass film, and the sealing cover 4 lowering as it descends, causing the atomizing nozzle 203 to descend and approach the tempered glass film. Then, the external oil supply equipment is controlled to supply anti-fingerprint oil to the atomizing nozzle 203, and the electric slider 202 is controlled to drive the atomizing nozzle 203 to slide back and forth on the slide rail 201, so that the anti-fingerprint oil is evenly atomized and sprayed onto the upper surface of the tempered glass film. During the oil spraying process, the sealing cover 4 and the sealing film 5 combine with the tempered glass film to form a closed chamber, preventing the high-speed sprayed oil mist from spreading to the surroundings and adhering to other sprayed or unsprayed tempered glass film surfaces after contacting the tempered glass film, thus avoiding uneven oil mist adhesion on the tempered glass film surface. At the same time, the sealing film 5 prevents the oil mist from being sprayed onto the upper side of the conveyor belt 2, and prevents the oil from adhering from the conveyor belt 2 to the back of the tempered glass film, thereby preventing the adhesive layer on the back of the tempered glass film from becoming less viscous and ensuring the quality of the produced tempered glass film.

[0027] After the anti-fingerprint oil is sprayed onto the surface of the tempered glass film, the electric slider 202 is controlled to move and reset the atomizing nozzle 203, and the atomizing nozzle 203 is controlled to stop spraying oil mist. Then, the telescopic drive 3 is controlled to move the sealing cover 4 and the sealing film 5 to rise and separate from the sprayed tempered glass film. As the sealing cover 4 rises, the atomizing nozzle 203 also rises. Then, the conveyor belt 2 is controlled to transport the sprayed tempered glass film to the drying zone 1001. The oil sprayed on the surface of the tempered glass film is dried and cured by the UV lamp in the drying zone 1001. Then, the dried tempered glass film is transported out of the drying zone 1001 by the conveyor belt 2. Finally, the flat tempered glass film is removed from the conveyor belt 2 by the external unloading mechanism. This invention realizes the cleaning, oiling and drying of tempered glass film in one, realizing multi-functional integration.

[0028] Furthermore, considering that the transmission belt 2 vibrates during the transport of the tempered glass film, causing the film to shift on the support rod 2001, the sealing film 5 cannot adhere to the shifted outer side of the tempered glass film during the oiling process. This not only reduces the oiling effect but also leads to oil mist leakage. Therefore, when the external feeding mechanism places the tempered glass film on the support rod 2001, it presses the film up and down on the support rod 2001 to ensure full contact between the tempered glass film and the fixed suction cup 2002. The fixed suction cup 2002 then adsorbs and fixes the lower side of the tempered glass film, preventing it from shifting on the support rod 2001 due to vibration. This ensures the adhesion of the sealing film 5 to the outer side of the tempered glass film and guarantees the oiling effect of the tempered glass film.

[0029] As the oiling process continues, the oil mist gradually adheres to the inner wall of the sealed cover 4. When the electric slider 202 drives the atomizing nozzle 203 to slide back and forth, the atomizing nozzle 203 drives the scraper 301 to scrape against the inner wall of the sealed cover 4, scraping the oil adhering to the inner wall of the sealed cover 4 down to the upper edge of the sealing membrane 5 and the contact position with the sealed cover 4. The collected oil is then collected by the suction pipe 302 through an external suction device, realizing the recovery of the oil and preventing oil waste. While suctioning the oil, the suction pipe 302 also suctions the oil mist diffused inside the sealed cover 4, which not only enhances the recovery effect of the anti-fingerprint oil, but also reduces the adhesion of oil mist to the inner wall of the sealed cover 4.

[0030] Furthermore, considering that the atomizing nozzle 203 sprays a large amount of oil, and the oil adhering to the inner wall of the sealed cover 4 has strong fluidity, when the scraper 301 is attached to the inner wall of the sealed cover 4 to scrape the oil, the oil is scraped quickly and rapidly converges, posing a risk of directly dripping onto the surface of the tempered glass film below and splashing onto adjacent tempered glass films, thus causing defective tempered glass films after oiling. Therefore, while the scraper 301 is attached to the inner wall of the sealed cover 4 to scrape the oil, the receiving plate 303 is used to receive and guide the converged dripping oil, preventing the oil from directly dripping onto the surface of the tempered glass film below and avoiding splashing and contaminating other tempered glass films. This ensures that the oil recovery operation does not affect the normal oiling process of the tempered glass film, thereby guaranteeing the finished product quality of the flat tempered glass film.

[0031] Example 2: Based on Example 1, as follows Figures 2-5 and Figure 7 As shown, it also includes a support plate 6 and a carrier plate 401; the support plate 6 and the carrier plate 401 are provided on the housing 1; the support plate 6 and the carrier plate 401 are both attached to the upper lower side of the conveyor belt 2; the distance between the right end face of the support plate 6 and the left end face of the carrier plate 401 is equal to the length of the drying zone 1001, so as to avoid affecting the drying of the tempered film by the drying zone 1001.

[0032] Each support rod 2001 is a hollow tube, which facilitates the separation of the tempered glass film from the fixed suction cup 2002 during subsequent material feeding, and avoids pulling and damaging the fixed suction cup 2002.

[0033] The upper surfaces of the support plate 6 and the carrier plate 401 are both made into smooth surfaces, which helps to reduce the wear of the support plate 6 and the carrier plate 401 on the transmission belt 2.

[0034] When the sealing cover 4 lowers the sealing membrane 5 to fit against the upper side of the conveyor belt 2, the support plate 6 provides rigid support to the lower side of the upper part of the conveyor belt 2 to prevent the sealing cover 4 and the sealing membrane 5 from being pressed down when they come into contact with the conveyor belt 2. This avoids the conveyor belt 2 pressing down and causing the tempered film to tilt, ensuring the flatness of the tempered film and enhancing the oiling effect on the tempered film. After the conveyor belt 2 conveys the dried tempered film out of the drying area 1001, the bearing plate 401 provides rigid support to the conveyor belt 2 to ensure that the external feeding suction cup remains flat when it comes into contact with the tempered film, improving the feeding repeatability accuracy.

[0035] Furthermore, considering that when the external feeding suction cup picks up the tempered glass film for feeding, the fixed suction cup 2002 adheres to and fixes the lower side of the tempered glass film. The external feeding suction cup pulls on the fixed suction cup 2002 during the feeding process, potentially damaging both the tempered glass film and the fixed suction cup 2002. Therefore, by using hollow tubes for the support rods 2001, when the external feeding mechanism presses the tempered glass film onto the support rods 2001, the lower side of the hollow support rods 2001 is blocked by the support plate 6, and the upper side of the fixed suction cup 2002 is blocked by the tempered glass film. This ensures the effective adsorption and fixation of the tempered glass film by the fixed suction cup 2002 during transport. After the tempered glass film is coated, it separates from the support plate 6 as the conveyor belt 2 carries it into the drying zone 100. 1. During drying, the lower side of the support rod 2001 separates from the support plate 6, allowing gas to enter between the fixed suction cup 2002 and the tempered film through the support rod 2001. This releases the fixed suction cup 2002 from adsorbing and fixing the tempered film. When the conveyor belt 2 carries the tempered film and is supported by the carrier plate 401, the tempered film is not pressed down on the fixed suction cup 2002 by external force. Even if the lower side of the support rod 2001 is blocked by the carrier plate 401, the fixed suction cup 2002 will not adsorb the tempered film. This ensures the flatness of the external feeding suction cup when it contacts the tempered film, improves the repeatability of feeding, and prevents the external feeding suction cup from pulling the tempered film and the fixed suction cup 2002 when it is feeding the tempered film, thus avoiding damage to the tempered film and the fixed suction cup 2002.
