Description
Technical Field
[0001] This utility model relates to the technical field of glass coating, specifically a coating device for tempered glass processing. Background Technology
[0002] Tempered glass, as a material with excellent safety performance, is widely used in various fields of modern society. Through chemical or physical methods, compressive stress is formed on the glass surface, greatly improving its strength and impact resistance, making it able to withstand significant external forces without easily breaking. Even if it does break, it shatters into small, blunt-angled particles, significantly reducing the risk of serious injury. Due to these superior properties, tempered glass is widely used in the construction industry, such as in doors, windows, curtain walls, and partitions, enhancing both the safety and aesthetics of buildings. In the automotive industry, tempered glass is an indispensable material for car windows and windshields, providing safety for passengers. In the furniture industry, tempered glass is commonly used to make coffee tables, dining tables, and glass cabinets, offering both aesthetic appeal and high durability. Furthermore, in the electronics industry, some high-end mobile phones and tablets also use tempered glass screens to improve the product's wear resistance and drop resistance.
[0003] In the processing of tempered glass, lamination is a crucial step. Lamination further enhances the performance of tempered glass, such as improving its scratch resistance and preventing surface contamination and damage. However, existing lamination equipment for tempered glass processing has several problems in practical use. Some lamination devices lack an effective positioning mechanism, causing the tempered glass to easily shift during positioning and lamination. This results in poor adhesion between the plastic film and the tempered glass, leading to wrinkles and other issues. Furthermore, air bubbles are prone to appearing after lamination, severely affecting the quality of the coating. Therefore, a new lamination device for tempered glass processing is needed to solve these problems. Summary of the Invention
[0004] (a) Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a coating device for tempered glass processing to solve the problems mentioned in the background art.
[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a coating device for tempered glass processing, comprising a tempered glass body, a conveying platform, a first mounting frame, a coating roller, and a guide roller. A conveyor belt is provided on the conveying platform. The first mounting frame is mounted on the top of the conveying platform. The coating roller is rotatably connected to the top area of the inner sidewall of the first mounting frame, and the guide roller is rotatably connected to the bottom area of the inner sidewall of the first mounting frame. The device also includes: The positioning mechanism and the pressing mechanism are both installed on the conveyor platform. The positioning mechanism reduces the possibility of the tempered glass body on the conveyor belt shifting during the film coating process, and the pressing mechanism reduces the possibility of air bubbles forming after the tempered glass body is coated. The pressing mechanism includes a second mounting frame, a lifting mechanism, a lifting plate, a buffer mechanism, and a scraper. The second mounting frame is connected to the top of the conveyor platform, the lifting mechanism is connected to the top of the second mounting frame, the lifting plate is connected to the bottom of the lifting mechanism, the buffer mechanism is connected to the bottom of the lifting plate, and the scraper is connected to the bottom of the buffer mechanism. The scraper is pressed tightly against the top of the coated tempered glass body, and the tempered glass body moves on the conveyor belt to achieve the purpose of compression, reducing the possibility of air bubbles after coating.
[0006] Preferably, the positioning mechanism includes two sets of fixed plates, two sets of first electric cylinders, and two sets of positioning plates. Both sets of fixed plates are connected to the top of the conveyor platform and are located at both ends of the conveyor belt. The two sets of first electric cylinders are respectively connected to the two sets of fixed plates, and the two sets of positioning plates are respectively connected to the output ends of the two sets of first electric cylinders. Two sets of first guide rods are slidably arranged on both sets of fixed plates, and the two sets of first guide rods are connected to the positioning plates.
[0007] Preferably, the buffer mechanism includes two sets of telescopic rods and two sets of springs. The bottom ends of the two sets of telescopic rods are connected to the top end of the scraper, and the two sets of telescopic rods are connected to the lifting and sliding mechanism. The two sets of springs are respectively fitted onto the two sets of telescopic rods. The bottom ends of the two sets of springs are connected to the top end of the scraper, and the top ends of the two sets of springs are connected to the bottom end of the lifting plate.
[0008] Preferably, the lifting mechanism includes a second electric cylinder and two sets of second guide rods. The second electric cylinder is connected to the top of the second mounting frame, and both sets of second guide rods are slidably connected to the second mounting frame. The bottom ends of the two sets of second guide rods and the output end of the second electric cylinder are both connected to the top of the lifting plate.
[0009] Preferably, both sets of positioning plates are provided with U-shaped grooves at their inner ends, and multiple sets of rollers are provided in the U-shaped grooves.
[0010] Preferably, the conveyor belt is provided with multiple sets of drive plates, and the drive plates are in contact with the tempered glass body.
[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a coating device for tempered glass processing, which has the following advantages: A positioning mechanism installed on the conveyor platform limits the position of the tempered glass body on the conveyor belt, significantly reducing the possibility of displacement during the lamination process. As the tempered glass moves under the laminating rollers driven by the conveyor belt, the positioning mechanism ensures that the tempered glass body remains in the center of the conveyor belt's movement direction. This allows the plastic film released by the laminating rollers to precisely align with the tempered glass surface, avoiding film misalignment and adhesion problems caused by glass displacement.
[0012] The clamping mechanism consists of a second mounting frame, a lifting mechanism, a lifting plate, a buffer mechanism, and a scraper. After the tempered glass body has undergone initial film coating, the height of the lifting plate can be flexibly adjusted via the lifting mechanism, which in turn drives the buffer mechanism and scraper to rise and fall synchronously, ultimately ensuring that the scraper fits tightly against the top of the coated tempered glass body. As the tempered glass body continues to move with the conveyor belt, the scraper exerts a continuous and uniform squeezing force on the film on the glass surface. This squeezing action gradually expels any residual air between the film and the tempered glass body, effectively reducing the probability of bubble formation. Simultaneously, the buffer mechanism prevents the scraper from causing rigid damage to the tempered glass or film, ensuring both effective bubble removal and protection of the glass and film, further guaranteeing the quality of the coated product.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0016] Please see Figures 1-4 A coating apparatus for tempered glass processing includes a tempered glass body 1, a conveying platform 2, a first mounting frame 3, a coating roller 4, and a guide roller 5. A conveyor belt 6 is mounted on the conveying platform 2. The first mounting frame 3 is mounted on the top of the conveying platform 2. The coating roller 4 is rotatably connected to the top region of the inner wall of the first mounting frame 3, and the guide roller 5 is rotatably connected to the bottom region of the inner wall of the first mounting frame 3. The apparatus also includes: The positioning mechanism and the pressing mechanism are both installed on the conveyor platform 2. The positioning mechanism reduces the possibility of the tempered glass body 1 on the conveyor belt 6 shifting during the film coating process, and the pressing mechanism reduces the possibility of air bubbles appearing after the tempered glass body 1 is coated. The pressing mechanism includes a second mounting frame 7, a lifting mechanism, a lifting plate 8, a buffer mechanism, and a scraper 9. The second mounting frame 7 is connected to the top of the conveyor platform 2, the lifting mechanism is connected to the top of the second mounting frame 7, the lifting plate 8 is connected to the bottom of the lifting mechanism, the buffer mechanism is connected to the bottom of the lifting plate 8, and the scraper 9 is connected to the bottom of the buffer mechanism. The scraper 9 is in close contact with the top of the coated tempered glass body 1, and the tempered glass body 1 moves on the conveyor belt 6 to achieve the purpose of squeezing and reduce the possibility of air bubbles after coating. A positioning mechanism installed on the conveyor platform 2 limits the movement of the tempered glass body 1 on the conveyor belt 6, significantly reducing the possibility of displacement during the lamination process. As the tempered glass moves under the lamination roller 4 driven by the conveyor belt 6, the positioning mechanism ensures that the tempered glass body 1 remains in the center of the conveyor belt 6's movement direction, allowing the plastic film released by the lamination roller 4 to precisely align with the tempered glass surface, avoiding film misalignment and adhesion problems caused by glass displacement.
[0017] The clamping mechanism consists of a second mounting bracket 7, a lifting mechanism, a lifting plate 8, a buffer mechanism, and a scraper 9. After the tempered glass body 1 has undergone initial film coating, the height of the lifting plate 8 can be flexibly adjusted via the lifting mechanism, which in turn drives the buffer mechanism and the scraper 9 to rise and fall synchronously, ultimately ensuring that the scraper 9 fits tightly against the top of the coated tempered glass body 1. As the tempered glass body 1 continues to move with the conveyor belt 6, the scraper 9 exerts a continuous and uniform squeezing force on the film on the glass surface. This squeezing action gradually expels any residual air between the film and the tempered glass body 1, effectively reducing the probability of bubble formation. At the same time, the buffer mechanism prevents the scraper 9 from causing rigid damage to the tempered glass or the film, ensuring both the defoaming effect and the protection of the glass and the film, further guaranteeing the quality of the coated product.
[0018] Please see Figures 1-4 The positioning mechanism includes two sets of fixed plates 10, two sets of first electric cylinders 11, and two sets of positioning plates 12. Both sets of fixed plates 10 are connected to the top of the conveyor platform 2 and are located at both ends of the conveyor belt 6. The two sets of first electric cylinders 11 are respectively connected to the two sets of fixed plates 10, and the two sets of positioning plates 12 are respectively connected to the output ends of the two sets of first electric cylinders 11. Two sets of first guide rods 13 are slidably arranged on both sets of fixed plates 10, and the two sets of first guide rods 13 are connected to the positioning plates 12. The positioning plate 12 is moved by the first electric cylinder 11. The distance between the two sets of positioning plates 12 can be flexibly adjusted according to the different sizes of tempered glass bodies 1, ensuring that glass of different sizes can be stably limited and avoiding positioning failure due to differences in glass size. The two sets of first guide rods 13 are slidably connected to the positioning plate 12, which can effectively limit the shaking or tilting of the positioning plate 12 during the movement, ensuring that the positioning plate 12 always moves smoothly along the width direction of the conveyor belt 6.
[0019] Please see Figures 1-4 The buffer mechanism includes two sets of telescopic rods 14 and two sets of springs 15. The bottom ends of the two sets of telescopic rods 14 are connected to the top end of the scraper 9. The two sets of telescopic rods 14 are connected to the lifting sliding connection. The two sets of springs 15 are respectively fitted to the two sets of telescopic rods 14. The bottom ends of the two sets of springs 15 are connected to the top end of the scraper 9. The top ends of the two sets of springs 15 are connected to the bottom end of the lifting plate 8. Spring 15 has elastic extension and contraction characteristics. When the scraper 9 comes into contact with the coated glass, spring 15 can adaptively compress or extend according to the slight undulations of the glass surface, avoiding rigid compression of the glass or coating by the scraper 9. The telescopic rod 14 can limit the extension and contraction direction of spring 15, ensuring that the elastic force of spring 15 always acts on scraper 9 in the vertical direction, ensuring that scraper 9 applies continuous and uniform squeezing force to the coating on the glass surface, more thoroughly expelling residual air between the coating and the glass, and further reducing the probability of bubble formation.
[0020] Please see Figures 1-4 The lifting mechanism includes a second electric cylinder 16 and two sets of second guide rods 17. The second electric cylinder 16 is connected to the top of the second mounting frame 7, and both sets of second guide rods 17 are slidably connected to the second mounting frame 7. The bottom ends of the two sets of second guide rods 17 and the output ends of the second electric cylinder 16 are both connected to the top of the lifting plate 8. The second electric cylinder 16 can achieve precise height control of the lifting plate 8 and can adjust the initial height of the scraper 9 according to the tempered glass body 1 of different thicknesses to ensure that the scraper 9 is tightly attached to the coated glass surface and adapts to the defoaming requirements of glass of different thicknesses. The two sets of second guide rods 17 are slidably connected to the second mounting frame 7 to limit the horizontal sway of the lifting plate 8 during the lifting process and ensure that the lifting plate 8 drives the scraper 9 to always move in the vertical direction.
[0021] Please see Figures 1-4 Both sets of positioning plates 12 have U-shaped grooves 18 at their inner ends, and multiple sets of rollers 19 are installed within the U-shaped grooves 18. The rollers 19 convert the sliding friction between the positioning plates 12 and the glass into rolling friction, significantly reducing the friction between the glass and the positioning plates 12 during the movement of the conveyor belt 6. This prevents scratches and wear on the glass edges caused by friction, ensuring the appearance quality of the processed glass. The multiple sets of rollers 19 are evenly distributed along the U-shaped grooves, which can provide auxiliary guidance for the movement direction of the glass, preventing the glass from jamming during positioning and limiting due to excessive frictional resistance. This ensures that the glass moves smoothly with the conveyor belt 6, providing smooth conditions for subsequent continuous operations such as lamination and defoaming.
[0022] Please see Figures 1-4 The conveyor belt 6 is equipped with multiple sets of driving plates 20, which are in contact with the tempered glass body 1. The driving plates 20 are in contact with the tempered glass body 1, and the glass can be moved directly by the driving plates 20, which solves the problem of slippage caused by the traditional conveyor belt 6 relying solely on friction.
[0023] In summary, when using this tempered glass processing coating device, the tempered glass body 1 is placed on the conveyor belt 6 of the conveyor platform 2. The conveyor belt 6 is started, and the tempered glass body 1 moves towards the first mounting frame 3 along with the conveyor belt 6. When the tempered glass body 1 moves to the positioning mechanism area, the driving component of the positioning mechanism pushes two sets of positioning plates 12 to move towards both sides of the tempered glass body 1 until the two sets of positioning plates 12 gently adhere to the edges of the glass. Under the limiting action of the positioning plates 12, the tempered glass body 1 is adjusted to the middle position in the direction of movement of the conveyor belt 6, preventing the tempered glass body 1 from tilting or shifting. Under the combined action of the conveyor belt 6 and the positioning mechanism, the tempered glass body 1 moves smoothly along the middle path towards the coating roller 4. The coating roller 4 performs the coating work on the tempered glass body 1. Since the positioning mechanism has ensured that the glass is not shifted in the early stage, the plastic film can be completely aligned with the glass surface, avoiding problems such as film misalignment and wrinkles caused by glass shift, thus completing the initial coating.
[0024] The tempered glass body 1, after initial coating, continues to move along the conveyor belt 6 and enters the pressing mechanism area. The lifting mechanism drives the lifting plate 8, the buffer mechanism, and the scraper 9 to descend synchronously until the scraper 9 is in close contact with the coating on the surface of the tempered glass body 1. At this time, the buffer mechanism adaptively compresses according to the contact pressure between the scraper 9 and the coating, ensuring that the scraper 9 applies a uniform and gentle squeezing force to the coating, avoiding damage to the coating or the glass. As the tempered glass body 1 continues to move along the conveyor belt 6, the scraper 9 exerts a continuous squeezing effect on the coating surface, gradually expelling the air remaining between the coating and the tempered glass body 1 towards the glass edge, effectively reducing the probability of bubble formation. After debubbling, the glass is moved out of the pressing mechanism area along the conveyor belt 6, finally completing the entire coating process and obtaining coated tempered glass without offset or bubbles.
[0025] The first electric cylinder 11 and the second electric cylinder 16 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, so we will not go into detail here. The first electric cylinder 11 and the second electric cylinder 16 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage requirements to facilitate operation and control by the operator.
[0026] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
