Description

Technical Field

[0001] This invention relates to the field of tempered glass screen protector production and processing equipment, specifically a coating equipment for producing tempered glass screen protectors for mobile phones. Background Technology

[0002] With the rapid development of the smartphone industry, tempered glass screen protectors have become an indispensable protective accessory for mobile phones, resulting in huge market demand. The large-scale production of tempered glass screen protectors involves laminating a protective film onto the surface of tempered glass substrates, followed by a series of processes such as cutting, flattening, and waste recycling of the laminated film to ensure the smoothness and quality of the finished product. As the core equipment in tempered glass screen protector production, the lamination equipment's positioning accuracy, lamination smoothness, waste disposal stability, and equipment adaptability directly determine the yield of finished tempered glass screen protectors and the overall production line efficiency. Therefore, high-performance, high-stability lamination equipment adaptable to multiple specifications has become an urgent need in the industry.

[0003] Existing traditional tempered glass film laminating equipment still has many shortcomings in actual production use. First, the substrate positioning structure of traditional equipment is simple, mostly using a fixed limiting structure, which cannot adaptively and accurately center and position the tempered glass substrate according to different specifications. During the lamination process, film material deviation and misalignment are very likely to occur. Moreover, there is a lack of visual inspection and correction structure, making it impossible to detect lamination deviations, bubbles, and surface defects in time. The quality of the laminated products is inconsistent, and the product defect rate is high. Second, the film material cutting and waste material winding structure of traditional laminating equipment is rudimentary. The cutting spacing is inconvenient to adjust and it is difficult to adapt to the processing of film materials of different widths. In addition, the waste material winding roller is fixed in position, and the excess film edge material after cutting is prone to local stacking, bulging, and deviation on the roller body, causing winding jamming and material breakage, which seriously affects the stability of continuous production. At the same time, the disassembly and assembly of the material cylinder of the traditional winding structure is cumbersome, and the downtime for changing materials is long. The overall versatility and continuous production efficiency of the equipment are low, which cannot meet the needs of modern multi-specification, high-precision, and automated mass production. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laminating equipment for producing tempered glass screen protectors for mobile phones, which solves the problems of low positioning accuracy, poor laminating quality, insufficient stability in edge cutting and winding, low adaptability, and low production efficiency of existing laminating equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coating equipment for producing tempered glass screen protectors for mobile phones includes a coating table. A first motor is installed on one side of the coating table. The output end of the first motor is connected to a first bidirectional threaded screw. Two first sliders are fitted on the first bidirectional threaded screw. A mounting plate is fixedly provided at the top of each of the two first sliders. A second motor is installed on one side of each of the two mounting plates. A take-up roller is connected to the output end of each of the two second motors. A baffle is provided on one side of each of the two take-up rollers. A magnetic card block is fixedly provided on each of the two baffles. A magnetic card slot is provided inside each of the two take-up rollers. A card slot is opened on each of the two take-up rollers.

[0007] Through the above technical solution, the first motor drives the first bidirectional threaded screw to rotate, which can drive the two sets of first sliders, mounting plates and take-up rollers to move synchronously in opposite directions or back and forth. The film-coated edge material produced by cutting is wrapped around the surface of the take-up roller. Relying on the lateral reciprocating movement of the take-up roller, the edge material is evenly distributed and wrapped, avoiding local accumulation of edge material that causes the material roll to bulge, deviate and jam. At the same time, the magnetic card block and the magnetic card slot magnetically cooperate to complete the positioning and clamping of the edge material cylinder. There is no need for cumbersome fasteners, which realizes the quick disassembly and replacement of the cylinder, effectively shortens the material change downtime and improves the continuous production capacity of the equipment.

[0008] Furthermore, a mounting frame is fixedly provided at the top of the coating table, a slide rail is provided inside the mounting frame, an electric slider is slidably provided inside the slide rail, and a vision detector is provided at the bottom of the electric slider;

[0009] Through the above technical solution, the electric slider can slide laterally along the slide rail, driving the vision detector to complete a large-area scanning acquisition. It can obtain the alignment status of the tempered glass substrate and the protective film in real time, identify various appearance defects such as film offset, bubbles, and surface impurities, provide detection basis for equipment position adjustment, facilitate timely detection of production abnormalities, and reduce the outflow of defective products.

[0010] Furthermore, a third motor is installed on one side of the coating table, and the output end of the third motor is connected to a second bidirectional threaded screw;

[0011] Through the above technical solution, the third motor provides forward and reverse driving power for the second bidirectional threaded screw. Relying on the transmission characteristics of the bidirectional thread, it can drive the sliders on both sides to achieve synchronous reverse movement, providing a stable and reliable transmission foundation for the adaptive centering and positioning of the tempered glass substrate. The transmission response is fast and the adjustment accuracy is high.

[0012] Furthermore, the second bidirectional threaded screw is fitted with two second sliders, and each of the two second sliders is fixedly provided with a positioning guide block at its top.

[0013] Through the above technical solution, under the driving action of the second bidirectional threaded screw, the two second sliders drive the positioning guide blocks to move synchronously towards or away from each other. This can automatically adjust the limit distance according to the tempered glass substrates of different widths and specifications, clamp and center the substrates from both sides, effectively overcome the positional deviation during the substrate transportation process, ensure the alignment accuracy of the subsequent lamination process, and improve the equipment's adaptability to products of multiple specifications.

[0014] Furthermore, a feeding plate is provided on one side of the coating table, a fourth motor is installed on the feeding plate, the output end of the fourth motor is connected to a third bidirectional threaded screw, and two third sliders are fitted on the third bidirectional threaded screw.

[0015] Through the above technical solution, the fourth motor drives the third bidirectional threaded screw to rotate, which drives the two third sliders to achieve synchronous reverse displacement, thereby adjusting the cutting distance between the two sets of cutters. It can be flexibly adjusted according to the width of the protective film and the actual size of the tempered film product. There is no need for manual adjustment of the single-sided blade position. The adjustment operation is convenient and it is suitable for edge cutting operations of various specifications of protective film.

[0016] Furthermore, two guide rods are slidably provided on the two third sliders, and a cutter is fixedly provided at the bottom end of each of the two third sliders;

[0017] Through the above technical solution, the guide slide rod plays a radial guiding and limiting role for the third slider, reducing the radial shaking caused by the screw drive, ensuring that the third slider moves smoothly without shaking, and the cutting trajectory is stable. This ensures that the cutting edges of the protective film are flat, reduces burrs and uneven cutting, and improves the cutting quality.

[0018] Furthermore, two mounting rods are installed on the feeding plate, and tensioning wheels are rotatably mounted on the two mounting rods;

[0019] Through the above technical solution, the tensioning wheel can rotate freely, continuously tensioning and constraining the protective film strip on the conveying path, eliminating the loosening and shaking phenomena during the film conveying process, avoiding local wrinkles and deviation of the film material, ensuring a smooth and orderly protective film feeding process, and providing good feeding conditions for subsequent lamination and cutting processes.

[0020] Furthermore, a feeding roller is rotatably installed inside the feeding plate, and conveying and flattening rollers are installed on both sides of the film covering table;

[0021] Through the above technical solution, the feeding roller is used to place the protective film roll, so as to realize the stable output of the protective film; the conveying and flattening roller can perform rolling operation on the tempered film that has been laminated, fully squeeze out the air trapped between the protective film and the tempered glass substrate, reduce lamination defects such as bubbles and curling edges, strengthen the bonding tightness between the protective film and the substrate, and effectively improve the quality of the finished product lamination.

[0022] This invention provides a coating equipment for producing tempered glass screen protectors for mobile phones. It has the following beneficial effects:

[0023] 1. This invention provides a coating equipment for producing tempered glass screen protectors for mobile phones. This device uses a third bidirectional threaded screw to drive the cutter to adjust the cutting spacing, which can cut excess edge material on both sides according to the actual width of the protective film. A first motor drives the first bidirectional threaded screw to drive the two winding rollers to move synchronously left and right, so that the cut excess coating edge material is evenly wrapped around the roller body, avoiding local stacking and bulging of edge material, winding deviation and jamming, and ensuring the stability of the edge material winding process. The winding rollers achieve quick disassembly and assembly of the material cylinder through magnetic attraction block and magnetic attraction slot, simplifying the edge material cylinder replacement operation, shortening the material change downtime, and improving the continuous production efficiency of the whole machine.

A sliding vision detector is used to detect laminating alignment and surface defects in real time, providing timely feedback on alignment deviations. A conveying and flattening roller performs rolling and air removal on the laminated protective film and substrate, reducing bubbles and wrinkles after lamination and improving the quality of the finished tempered glass screen protector. Furthermore, the device is adaptable to various specifications of tempered glass substrates, demonstrating strong versatility. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-6 As shown, this embodiment of the invention provides a coating equipment for producing tempered glass screen protectors for mobile phones, including a coating table 1. A first motor 2 is installed on one side of the coating table 1. The output end of the first motor 2 is connected to a first bidirectional threaded screw 3. Two first sliders 4 are fitted on the first bidirectional threaded screw 3. Mounting plates 5 are fixedly installed at the top of each of the two first sliders 4. A second motor 6 is installed on one side of each of the two mounting plates 5. A take-up roller 7 is connected to the output end of each of the two second motors 6. A baffle 8 is provided on one side of each of the two take-up rollers 7. A magnetic suction block 9 is fixedly installed on each of the two baffles 8. A magnetic suction slot 10 is provided inside each of the two take-up rollers 7. Each of the 7 has a slot 11. The first motor 2 drives the first bidirectional threaded screw 3 to rotate, which can drive the two sets of first sliders 4, mounting plates 5 and take-up rollers 7 to move back and forth in opposite directions at the same time. The film-coated edge material produced by cutting is wrapped around the surface of the take-up roller 7. Relying on the lateral reciprocating movement of the take-up roller 7, the edge material is evenly distributed and wrapped, avoiding local accumulation of edge material that causes the material roll to bulge, deviate and jam. At the same time, the magnetic card block 9 and the magnetic card slot 10 magnetically cooperate to complete the positioning and clamping of the edge material cylinder. There is no need for cumbersome fasteners, which realizes the quick disassembly and replacement of the cylinder, effectively shortens the material change downtime and improves the continuous production capacity of the equipment.

[0035] A mounting frame 12 is fixedly installed at the top of the laminating table 1. A slide rail 13 is provided inside the mounting frame 12, and an electric slider 14 slides within the slide rail 13. A vision detector 15 is installed at the bottom of the electric slider 14. The electric slider 14 can slide laterally along the slide rail 13, driving the vision detector 15 to complete a large-area scanning acquisition. This allows for real-time acquisition of the alignment status between the tempered glass substrate and the protective film, identifying various appearance defects such as lamination misalignment, bubbles, and surface impurities. This provides a detection basis for equipment position adjustment, facilitating timely detection of production anomalies and reducing the outflow of defective products. A third motor 16 is installed on one side of the laminating table 1. The output end of the third motor 16 is connected to a second bidirectional threaded screw 17. The third motor 16 provides forward and reverse drive power to the second bidirectional threaded screw 17. Utilizing the transmission characteristics of the bidirectional thread, the sliders on both sides can be driven to move synchronously in opposite directions, providing a stable and reliable transmission foundation for the adaptive centering and positioning of tempered glass substrates. The transmission response is fast and the adjustment accuracy is high. Two second sliders 18 are fitted onto the second bidirectional threaded screw 17, each with a fixed positioning guide block 19 at its top. Under the drive of the second bidirectional threaded screw 17, the two second sliders 18 drive the positioning guide blocks 19 to move synchronously towards or away from each other. This allows for automatic adjustment of the limit spacing according to the width and specifications of the tempered glass substrates, clamping and centering the substrates from both sides. This effectively overcomes positional offset during substrate transport, ensuring the alignment accuracy of subsequent lamination processes and improving the equipment's adaptability to multiple product specifications. 1. A feeding plate 20 is provided on one side, and a fourth motor 21 is installed on the feeding plate 20. The output end of the fourth motor 21 is connected to a third bidirectional threaded screw 22. Two third sliders 23 are fitted on the third bidirectional threaded screw 22. The fourth motor 21 drives the third bidirectional threaded screw 22 to rotate, thereby driving the two third sliders 23 to achieve synchronous reverse displacement, thus adjusting the cutting distance between the two sets of cutters. It can be flexibly adjusted according to the width of the protective film and the actual size of the tempered film product. There is no need for manual adjustment of the blade position on one side. The adjustment operation is convenient and suitable for edge cutting of various specifications of protective film. Two guide slides 24 are slidably provided on the two third sliders 23. A cutter 25 is fixed at the bottom of each of the two third sliders 23. The guide slides 24 guide the third sliders 23. The feed plate 20 serves as a radial guide and limiting constraint, reducing radial wobble caused by the screw drive and ensuring smooth, vibration-free movement of the third slider 23 and stable trajectory of the cutter 25. This ensures a clean cut on both sides of the protective film edge material, reducing burrs and uneven cutting, and improving cutting quality. Two mounting rods 26 are installed on the feeding plate 20, each with a rotatable tension wheel 27. The tension wheel 27 rotates freely, continuously tensioning the protective film strip along the conveying path, eliminating slack and vibration during film conveying, preventing localized wrinkles and deviations in the film material, and ensuring a smooth and orderly feeding process. This provides good feeding conditions for subsequent lamination and cutting processes. A feeding roller 28 rotates within the feeding plate 20.Both sides of the laminating table 1 are equipped with conveying and flattening rollers 29, and the feeding roller 28 is used to hold the protective film roll, achieving a stable output of the protective film. The conveying and flattening rollers 29 can perform a rolling operation on the already laminated tempered glass film, fully squeezing out the air trapped between the protective film and the tempered glass substrate, reducing lamination defects such as bubbles and curling edges, strengthening the adhesion between the protective film and the substrate, and effectively improving the quality of the finished lamination.

[0036] Working Principle: This equipment is used to laminate PET protective film onto tempered glass substrates. During operation, the protective film roll is installed on the feeding roller 28. The protective film strip is tensioned and guided by the tensioning roller 27 to prevent slackness, deviation, and wrinkles during film conveying. The fourth motor 21 drives the third bidirectional threaded screw 22 to rotate, causing the two third sliders 23 to move towards or away from each other along the guide slide 24. The distance between the two cutters 25 is adjusted according to the actual width of the tempered film to be processed, and the excess edge material on both sides of the protective film is cut off. The tempered glass substrate to be laminated is conveyed to the laminating table 1. The third motor 16 drives the second bidirectional threaded screw 17 to rotate, driving the two sets of... The two sliders 18 and the positioning guide blocks 19 move towards each other. The two sets of positioning guide blocks 19 limit and center the tempered glass substrate from both sides, correct the positional deviation of the substrate, ensure the accuracy of the subsequent lamination position, and prevent lamination offset and misalignment problems. The first motor 2 drives the first bidirectional threaded screw 3 to rotate, which drives the two first sliders 4 to move the mounting plate 5 and the winding roller 7 to move synchronously from left to right and back to back. The excess edge material on both sides generated after the protective film is cut is wrapped around the winding roller 7. Through the reciprocating left and right displacement of the winding roller 7 with the first bidirectional threaded screw 3, the excess edge material of the cut lamination can be... The protective film edge material is evenly wound onto the surface of the take-up roller 7 to prevent edge material from piling up in certain areas of the roller body, causing bulging and misalignment of the roll. The protective film edge material canister is quickly clamped and fixed by magnetic attraction between the magnetic block 9 on the baffle 8 and the magnetic slot 10 on the take-up roller 7, enabling quick disassembly and replacement of the canister. The second motor 6 drives the take-up roller 7 to rotate, providing winding power for excess film edge material. The electric slider 14 mounted on the slide rail 13 of the mounting frame 12 drives the vision detector 15 to perform lateral sliding scan, acquiring real-time alignment images of the tempered substrate and the protective film, and detecting alignment deviations, bubbles, and foreign matter defects between the substrate and the protective film. This provides feedback for equipment position adjustment. After the substrate is positioned, the protective film strip is output and the protective film is adhered to the surface of the tempered glass substrate. The conveying and flattening rollers 29 on both sides of the laminating table 1 roll the adhered film and substrate to squeeze out the air between the protective film and the tempered glass, eliminate the air bubbles generated during lamination, and complete the pressing and lamination. The cutter 25 at the feeding plate 20 cuts off the excess edge material on both sides of the protective film. The excess edge material on both sides is evenly wound up by the corresponding winding roller 7. The whole set of equipment completes the entire process of positioning, alignment, lamination and flattening, edge material cutting, and even edge material winding of the tempered film in a cycle.
