Description

Technical Field

[0001] This invention relates to the field of capping machine equipment technology, and in particular to a coating equipment for insulating tempered glass. Background Technology

[0002] With the increasing demand for building energy conservation and decoration, insulated tempered glass is widely used in building curtain walls, doors and windows due to its excellent heat insulation, sound insulation and safety properties. In order to further enhance the optical performance of insulated tempered glass (such as increasing the shading coefficient, reducing reflectivity, and forming various decorative effects), functional film layers are usually coated on the glass surface.

[0003] Currently, the main coating methods for tempered glass include magnetron sputtering, chemical vapor deposition, and liquid coating. Among them, liquid coating has attracted attention due to its low equipment cost, simple process, and ability to flexibly prepare films with different functions (such as Low-E films, self-cleaning films, and decorative films).

[0004] Existing tempered glass coating equipment typically uses roller coating or spray coating methods to apply coatings to the glass surface. However, existing technical solutions generally have the following shortcomings: Single-sided coating issues: Most equipment can only coat the upper surface of the glass, failing to coat both sides simultaneously, resulting in low production efficiency. Film damage issues: After coating, the film is transferred directly by the conveyor rollers before curing, easily causing scratches, indentations, or uneven thickness on the film surface, affecting coating quality and yield. Poor coating uniformity: The coating mechanism is usually fixed, making it difficult to repeatedly coat and recoat different areas of the glass, failing to guarantee uniform coating over large areas. Support interference issues: During the glass coating process, the lack of reliable auxiliary support mechanisms makes the glass prone to vibration or deformation, affecting coating accuracy. Therefore, it is necessary to design a new type of coating equipment for insulated tempered glass to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues and the technical shortcomings of existing tempered glass coating equipment, such as low single-sided coating efficiency, easy damage to the coating layer during transport, poor coating uniformity, and lack of reliable support for the glass during coating, this paper provides a coating equipment for insulating tempered glass that enables simultaneous coating of both sides of the glass, avoids damage to the coating layer during transport, improves coating uniformity, and ensures stable support for the glass during the coating process.

[0006] The solution is a coating equipment for insulating tempered glass, including a frame. A central roller assembly, which can be raised and lowered, is located in the middle of the frame. A left roller assembly is located to the left of the central roller assembly, and a right roller assembly is located to the right of the central roller assembly. A coating mechanism is located between the left and right roller assemblies. The coating mechanism is connected to a linear drive mechanism installed below the central roller assembly. Two suction cup fixing assemblies are provided between the central roller assembly and the left roller assembly, as well as between the central roller assembly and the left roller assembly. The coating mechanism includes an upper... The upper and lower paint boxes are separated by a lower partition. Each side of the upper paint box has an upper mounting plate, and an upper paint roller and an upper feed roller are located between the two upper mounting plates. One end of the upper paint roller and the upper feed roller is equipped with an upper drive mechanism. Each side of the lower paint box has a lower mounting plate, and a lower paint roller and a lower feed roller are located between the two lower mounting plates. One end of the lower paint roller and the lower feed roller is equipped with a lower drive mechanism. The lower end of the upper paint roller is located at the lower part of the upper paint box, and the upper end of the lower paint roller is located at the upper end of the lower paint box.

[0007] Preferably, the linear drive mechanism adopts a synchronous belt linear module. The central roller group includes a central support frame, a conveyor roller mounted on the support, a motor that drives the conveyor roller to rotate, and a transmission mechanism. A central connecting frame is fixed below the center of the central support frame. The synchronous belt linear module passes through the central connecting frame. The central connecting frame is connected to a lifting cylinder mounted on the frame.

[0008] Preferably, the application mechanism further includes an application support frame, on both sides of which drive screws are mounted. The drive screws are helically connected to an upper mounting plate and a lower mounting plate on the same side. The drive screws have upper and lower threads. The drive screws are helically connected to the upper mounting plate via the upper thread and to the lower mounting plate via the lower thread. The upper and lower threads have the same pitch but opposite spiral directions. Synchronous pulleys are mounted on the lower part of both screws, and a synchronous belt is provided between the two pulleys. Either of the two screws is coaxially fixedly connected to a drive shaft, which is connected to an application drive motor. Two guide rods are symmetrically arranged on both sides of each drive rod. The guide rods pass upward through the lower and upper mounting plates and slide vertically connected to them.

[0009] The suction cup fixing assembly includes a suction cup mounting plate fixed on the frame. The upper part of the suction cup mounting plate is provided with a suction cup, the middle part of the suction cup mounting plate is provided with a support hole, the support hole is provided with a support rod, the upper part of the support rod is provided with a roller located inside the suction cup, and the lower part of the support rod is provided with a suction cup cylinder mounted on the frame.

[0010] Preferably, the support rod is provided with a sealing ring. When the sealing ring enters the support hole, the suction cup mounting plate, the suction cup, and the support rod form an upward-opening suction cup cavity. When the sealing ring seals with the suction cup mounting plate, the roller is located at the lowest point, and the uppermost part of the roller is lower than the highest point of the left roller group.

[0011] The beneficial effects of this invention are as follows: It achieves simultaneous double-sided coating, improving production efficiency. The coating mechanism includes an upper coating box and a lower coating box spaced apart vertically. The upper and lower coating rollers can simultaneously coat the upper and lower surfaces of the glass, significantly improving efficiency compared to existing single-sided coating equipment. It avoids damage to the coating layer, improving coating quality. By setting up a vertically movable central roller group and surrounding suction cup fixing components, after coating, the glass is lifted by the suction cup fixing components, the central roller group descends and detaches from the glass, and then the central roller group lifts the glass and transfers it to the next process. The entire transfer process does not require direct contact between the glass film layer and the conveyor rollers, effectively avoiding problems such as scratches or indentations on the coating layer. It also achieves high coating uniformity and allows for repeated coating. The coating mechanism operates on a synchronous belt in a straight line. Driven by the module, it can perform lateral linear motion, sequentially coating different areas of the glass, and can repeatedly coat from left to right and then from right to left, ensuring the uniformity of coating large areas of glass and the stability of film thickness. The spacing between the coating boxes is adjustable, offering high flexibility. Through the drive screw and synchronous belt transmission mechanism, the upper and lower coating boxes can move towards or away from each other, flexibly adjusting the spacing according to different glass thicknesses. During coating, the glass is pressed tightly, and during transportation, they move aside to avoid interference. The support is stable and reliable, and the coating precision is high. Four suction cup fixing components are symmetrically arranged around the central roller group. During the coating process, the four corners of the glass are stably attracted and fixed by the suction cups, while the rollers inside the suction cups provide the main load-bearing support, avoiding glass vibration and deformation, and ensuring coating precision.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 6 A coating equipment for insulating tempered glass is provided, comprising a frame 1, a central roller group 2 that can be raised and lowered in the middle of the frame 1, a left roller group 3 on the left side of the central roller group 2, and a right roller group 4 on the right side of the central roller group 2. The equipment is characterized in that a coating mechanism 5 is provided between the left roller group 3 and the right roller group 4. The coating mechanism 5 is connected to a linear drive mechanism installed below the central roller group 2. Under the drive of the linear drive mechanism, the coating mechanism 5 can perform transverse linear movement between the left roller group 3 and the right roller group 4. The left roller group 3 and the right roller group 4 are both independent roller conveyors.

[0021] The middle roller group 2 and the left roller group, as well as the middle roller group 2 and the left roller group, are each equipped with two suction cup fixing components 6; the suction cup fixing components 6 on the same side are located on both sides of the middle roller group 2, and the four suction cup 19 components are located around the middle roller group 2.

[0022] The coating mechanism 5 includes an upper coating box 7 and a lower coating box spaced apart vertically. An upper mounting plate 8 is fixed to both sides of the upper coating box 7. An upper coating roller 9 and an upper feed roller 10 are positioned between the two upper mounting plates 8. An upper drive mechanism is provided at one end of the upper coating roller 9 and the upper feed roller 10. A lower mounting plate is fixed to both sides of the lower coating box. A lower coating roller and a lower feed roller are positioned between the two lower mounting plates. A lower drive mechanism is provided at one end of the lower coating roller and the lower feed roller. The lower end of the upper coating roller 9 is located at the lower part of the upper coating box 7, and the upper end of the lower coating roller is located at the upper end of the lower coating box. When glass requires double coating, this device prevents the glass from directly entering the conveyor roller after coating, thus avoiding damage to the coating layer. Glass is conveyed forward from the left conveyor roller. The coating mechanism 5 moves to the left conveyor roller under the drive of the linear drive mechanism. The coating roller coats the glass at the right end. Then the glass enters the middle roller group 2. Driven by the middle roller group 2, the glass stops completely on the middle roller group 2. Then the middle roller group 2 descends, and the four feet of the glass are supported by the four washing tray fixing mechanisms. Then the coating mechanism 5 coats the glass from left to right, and then coats it again from right to left. Then the middle roller group 2 rises to lift the glass. The suction cup 19 fixing mechanism disengages from the glass. The middle roller group 2 continues to transfer the glass to the right. The coating mechanism 5 coats the uncoated parts on the left side of the glass, thus completing the coating and coating of the entire glass.

[0023] The linear drive mechanism employs a synchronous belt linear module 11. The central roller assembly 2 includes a central support frame, conveyor rollers mounted on the support, a motor driving the conveyor rollers, and a transmission mechanism. A central connecting frame 12 is fixed below the center of the central support frame. The synchronous belt linear module 11 passes through the central connecting frame 12, and the central connecting frame 12 is connected to a lifting cylinder 13 mounted on the frame 1. The lifting cylinder 13 drives the central roller assembly 2 to move up and down. The central roller assembly 2 is a roller conveying mechanism, including a motor and a chain drive mechanism, capable of independently conveying glass. The coating mechanism 5 is mounted on the synchronous belt linear module 11 and can move laterally left and right under the drive of the synchronous belt linear module 11. The central connecting frame 12 and the synchronous belt linear module 11 do not interfere with each other; their movements do not affect each other. This ensures that the lifting cylinder 13 is located below the center of the central roller assembly 2, and also that the synchronous belt linear module 11 is located below the central roller assembly 2.

[0024] The application mechanism 5 also includes an application support frame. Drive screws 14 are mounted on both sides of the application support frame. The drive screws 14 are helically connected to the upper mounting plate 8 and the lower mounting plate on the same side. The drive screws 14 have upper and lower threads. The drive screws 14 are helically connected to the upper mounting plate 8 via the upper thread and to the lower mounting plate via the lower thread. The upper and lower threads have the same pitch but opposite spiral directions. Synchronous pulleys 15 are mounted on the lower part of both screws, and a synchronous belt is provided between the two pulleys 15. A drive shaft is coaxially fixed to either of the two screws. The drive shaft is connected to an application drive motor 16. Two guide rods 17 are symmetrically arranged on both sides of each drive rod. The guide rods 17 pass upward through the lower mounting plate and the upper mounting plate 8 and slide vertically connected to them. The coating drive motor 16 drives the drive shaft to rotate, which in turn drives the drive screw 14 connected to it to rotate. This, in turn, drives another drive screw 14 to rotate via the synchronous pulley 15 and synchronous belt, causing the upper coating box 7 and the lower coating box to move towards or away from each other. When coating is required on the glass, the upper and lower coating boxes move in opposite directions to a suitable position to apply coating and achieve a coating on the glass. When the glass is conveyed by the central roller group 2, the upper and lower coating boxes move in opposite directions under the drive of the drive screw 14, ensuring that the glass is not interfered with by the coating mechanism during transport.

[0025] The suction cup fixing assembly 6 includes a suction cup mounting plate 18 fixed to the frame 1. A suction cup 19 is located on the upper part of the suction cup mounting plate 18. A support hole is located in the middle of the suction cup mounting plate 18, and a support rod 20 is located inside the support hole. A roller 21 located inside the suction cup 19 is located on the upper part of the support rod 20. A roller 21 bracket is located on the support rod 20, and the roller 21 is rotatably connected to the roller 21 bracket. The western middle of the roller 21 bracket is fixedly connected to the upper part of the support rod 20. The axis of the roller 21 is perpendicular to and intersects the axis of the support rod 20. A suction cup cylinder 22 is mounted on the frame 1 at the lower part of the support rod 20. Four suction cup fixing assemblies 6 are provided, located around the central roller group 2, serving to support the glass during coating application.

[0026] The support rod 20 is provided with a sealing ring. When the sealing ring enters the support hole, the suction cup mounting plate 18, the suction cup 19, and the support rod 20 form an upward-opening suction cup 19 cavity. When the sealing ring seals with the suction cup mounting plate 18, the roller 21 is located at the lowest point, and the uppermost part of the roller 21 is lower than the highest point of the left roller group 3. When the glass needs to be placed on the rollers 21 after the middle roller group 2 completes its support, all four rollers 21 are at their lowest position. The middle roller group 2 moves downward under the drive of the lifting cylinder 13. The four corners of the glass are supported by the four suction cup fixing components 6. When the glass falls onto the suction cup 19, the gas inside the suction cup 19 is compressed out, forming a vacuum inside the suction cup 19, which can firmly adsorb and fix the suction cup 19. The glass is in contact with the rollers 21, and its main force is supported by the rollers 21. After the glass coating is completed, the four cylinders rise simultaneously to lift the glass. At the same time, the sealing ring disengages from the suction cup mounting plate 18, gas enters the suction cup 19, and then the suction cup 19 separates from the glass. The glass is supported by the four rollers 21. Then the middle roller group 2 further lifts the glass to be flush with the left roller group 3 and the right roller group 4. Then the conveying roller of the middle roller group 2 rotates to transport the glass to the right roller group 4. The glass is then transported to the next process by the right roller group 4.

[0027] The beneficial effects of this invention are as follows: It achieves simultaneous double-sided coating, improving production efficiency. The coating mechanism 5 includes an upper coating box 7 and a lower coating box spaced apart vertically. The upper coating roller 9 and the lower coating roller can simultaneously coat the upper and lower surfaces of the glass, significantly improving efficiency compared to existing single-sided coating equipment. It avoids damage to the coating layer, improving coating quality. By setting up a vertically movable central roller group 2 and surrounding suction cup fixing components 6, after coating, the glass is lifted by the suction cup fixing components 6, the central roller group 2 descends to detach from the glass, and then the central roller group 2 lifts the glass and transfers it to the next process. The entire transfer process does not require direct contact between the glass film layer and the conveyor rollers, effectively avoiding problems such as scratches or indentations on the coating layer. It also achieves high coating uniformity and allows for repeated coating. The coating mechanism 5 is located on a synchronous belt linear module. Driven by 11, it can perform lateral linear motion, enabling sequential coating of different areas of the glass, and can repeatedly coat from left to right and then from right to left, ensuring the uniformity of coating on large areas of glass and the stability of film thickness; the spacing between the paint boxes is adjustable, providing high flexibility. Through the drive screw 14 and synchronous belt transmission mechanism, the upper paint box 7 and the lower paint box can move towards or away from each other, allowing for flexible adjustment of the spacing according to different glass thicknesses. During coating, the glass is pressed tightly, and during transportation, it moves aside to avoid interference; the support is stable and reliable, and the coating precision is high. The four suction cup fixing components 6 are symmetrically arranged around the central roller group 2. During the coating process, the four corners of the glass are stably adsorbed and fixed by the suction cups 19, while the rollers 21 inside the suction cups 19 provide the main load-bearing support, avoiding glass vibration and deformation, and ensuring coating precision.
