Description

Technical Field

[0001] This utility model relates to the field of laminated glass cutting technology, specifically to a laminated glass cutting device for tempered glass production. Background Technology

[0002] Laminated glass, especially laminated glass with tempered glass as the base layer, is widely used in building curtain walls, doors and windows, automobile windshields, furniture, and various high-end equipment panels due to its excellent safety, sound insulation, heat insulation, and impact resistance. Its manufacturing process typically involves sandwiching one or more layers of tough interlayer such as polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) between two or more sheets of tempered glass. Through processes such as heating, pressurizing, and vacuuming, the glass and interlayer are firmly bonded together.

[0003] Laminated glass is a type of safety glass made by permanently bonding two or more sheets of tempered glass together with a tough polyvinyl butyral (PVB) film, SGP film, or other polymer composite film. A key step in its production is "laminated glass," which involves laying the film between the cleaned glass sheets to form a "glass-film-glass" laminated structure. Then, any film exceeding the glass specifications is cut to match the dimensions of the glass sheets.

[0004] Current film cutting methods involve manual cutting by operators using cutting knives or scissors with the aid of templates. This method is labor-intensive, inefficient, and heavily reliant on the operator's skill level, making it difficult to guarantee cutting accuracy and consistency, and easily leading to the aforementioned dimensional deviation problems. Summary of the Invention

[0005] The purpose of this invention is to address the problem that film cutting in the prior art relies on manual labor, and to provide a laminated cutting device for tempered glass production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laminated glass cutting device for tempered glass production, comprising: Roller conveyors are used to transport laminated glass sheets along the production line direction. The film clamping mechanism is symmetrically arranged on both sides of the roller conveyor to clamp and stretch the free end of the film outward so that the film is kept taut. A cutting mechanism, installed on the film clamping mechanism, is used to cut the film close to the edge of the laminated glass when the film is in a taut state.

[0007] Furthermore, the film clamping mechanism includes a carrying component and a pressing component. The carrying component is installed on the side of the roller conveyor, and the pressing component is located above the carrying component. The pressing component and the carrying component can press against each other to clamp the film, and after clamping, they move outward together to stretch the film.

[0008] Furthermore, the carrier component includes The guide rail is fixedly installed on the side of the roller conveyor, and its extension direction is perpendicular to the conveying direction of the laminated glass. The support plate is movably mounted on the guide rail; A drive source, connected to the carrier plate, is used to drive the carrier plate to move along the guide rail.

[0009] Furthermore, the pressing assembly includes: The mounting frame is U-shaped, with one end fixed to the side of the roller conveyor and the other end extending above the bearing assembly. The mounting frame is provided with an elongated hole perpendicular to the glass conveying direction and a cutting groove for the cutting mechanism to move. A transverse guide rail is fixedly installed on the mounting bracket and located on one side of the elongated hole; The transverse sliding plate is slidably connected to the transverse sliding guide rail; A driving component, mounted on the mounting bracket, is used to drive the transverse plate to move along the transverse guide rail; The lifting motor is fixedly installed on the transverse plate, and the output end of the lifting motor passes through the elongated hole; The pressing plate is connected to the output end of the lifting motor and is driven by the lifting motor to move vertically, thereby cooperating with the bearing component to press or loosen the film.

[0010] Furthermore, the cutting mechanism includes a cutting track, a cutting lifting motor, and a cutting blade. The cutting track is used to drive the cutting motor to move along the cutting groove, and the cutting blade is provided on the output end of the cutting motor.

[0011] The beneficial effects of this invention, achieved by adopting the above technical solution, are as follows: The film clamping mechanism symmetrically clamps the free ends of the film on both sides of the laminated glass and stretches them outwards to keep the film taut, thereby eliminating wrinkles. Subsequently, the cutting mechanism cuts close to the edge of the laminated glass while the film is taut, ensuring a straight and smooth cut. Throughout the process, the roller conveyor is responsible for transporting the laminated glass, and all components work together to achieve automated cutting, improving production efficiency and product quality.

[0012] Replacing manual labor, the film, after being stretched and tightened outwards by the clamping mechanism, has a smooth, wrinkle-free surface and uniform internal stress. This allows the cutting blade to make clean, crisp cuts with straight, smooth edges, free of burrs or tears. Because the cutting mechanism moves along a fixed cutting track and is close to the edge of the laminated glass, it ensures that the film cut edges of all products are straight, greatly improving the appearance quality and consistency of the products.

[0018] See Figure 1-3 As shown, the technical solution adopted in this specific embodiment is: a laminated glass cutting device for tempered glass production. This device is used to cut off the excess film on the edge of the laminated glass after lamination during the production process. Its main components include a roller conveyor 1, a film clamping mechanism 2, and a cutting mechanism 3.

[0019] Roller conveyor 1 is set along the production line direction and is used to transport laminated glass that has been laminated.

[0020] The film clamping mechanism 2 is symmetrically arranged on both sides of the roller conveyor 1. Its core function is to clamp the free end of the film and stretch it outward, so that the film remains taut throughout the cutting process, creating conditions for subsequent precise cutting.

[0021] The film clamping mechanism 2 is composed of a bearing component 21 and a pressing component 22 working together. Support assembly 21: Fixed to the side of roller conveyor 1, used to support the film from below. It includes: Guide rail 211: Fixed installation, its extension direction is perpendicular to the conveying direction of the laminated glass.

[0022] Support plate 212: Movably mounted on guide rail 211, used to directly support the film.

[0023] Drive source 213: connected to the support plate 212, used to drive the support plate 212 to move along the guide rail 211, thereby achieving outward stretching after clamping.

[0024] Pressing assembly 22: Located above the carrier assembly 21, it is used to press the film from above. It includes: Mounting bracket 221: U-shaped, one end fixed to the side of roller conveyor 1, and the other end extending above the bearing assembly 21. Mounting bracket 221 has an elongated hole 2211 perpendicular to the glass conveying direction, and a cutting groove 2212 for the cutting mechanism 3 to move.

[0025] Transverse guide rail 222: fixed on mounting bracket 221, located on one side of elongated hole 2211.

[0026] Horizontal sliding plate 223: slidably connected to horizontal sliding guide rail 222.

[0027] Drive component 224: mounted on mounting bracket 221, used to drive transverse plate 223 to move along transverse guide rail 222 to adjust the pressing position.

[0028] Lifting motor 225: fixed on the horizontal plate 223, its output end passes downward through the elongated hole 2211 on the mounting bracket 221.

[0029] Pressing plate 226: Connected to the output end of lifting motor 225, driven by lifting motor 225 to move vertically, thereby cooperating with the bearing plate 212 below to press or loosen the film.

[0030] The cutting mechanism 3 is mounted on the film clamping mechanism 2 and is used to cut the film close to the edge of the laminated glass after the film is stretched. It includes: Cutting track 31: used to guide and drive the cutting motor to move along the cutting groove 2212 on the mounting bracket 221.

[0031] Cutting lifting motor 32: Installed on cutting track 31, it can move along the track.

[0032] Cutting blade 33: Installed on the output end of the cutting lifting motor 32, and driven by the motor to complete the cutting action.

[0033] The working principle of this utility model: Although not shown in the diagram, this device should actually be equipped with sensors and a vision system.

[0034] Glass conveying and positioning: The laminated glass (consisting of two layers of glass and an interlayer film) is conveyed along the production line direction by roller conveyor 1 to the designated cutting station. Roller conveyor 1 is usually driven by a motor to ensure smooth glass movement and accurate positioning.

[0035] Film clamping and stretching: Clamping Initialization: When the laminated glass reaches the cutting station, the film clamping mechanism 2 begins to operate. The bearing assembly 21 and the pressing assembly 22, symmetrically arranged on both sides of the roller conveyor 1, work together (if the free end of the film is not within the pressing assembly 22, it is inserted by the operator during this process): The carrier plate 212 of the carrier assembly 21 is located on the side of the roller conveyor 1 and is driven by the drive source 213 (such as a cylinder or servo motor) and can move along the guide rail 211 (perpendicular to the glass conveying direction).

[0036] The lifting motor 225 of the pressing assembly 22 drives the pressing plate 226 to descend and press against the support plate 212, thereby clamping the free end of the film. The lifting of the pressing plate 226 is controlled by the lifting motor 225 to ensure uniform clamping force.

[0037] Stretching the film: After clamping, the drive source 213 drives the support plate 212 to move outward along the guide rail 211 (away from the center of the glass). At the same time, the drive component 224 of the pressing assembly 22 (such as a linear motor or cylinder) drives the transverse plate 223 to move along the transverse guide rail 222, causing the pressing plate 226 to move outward synchronously. In this way, the film clamping points on both sides are stretched outward together, making the film taut and the surface flat without wrinkles.

[0038] Film cutting: Cutting preparation: After the film is taut, the cutting mechanism 3 is started. The cutting mechanism 3 is mounted on the mounting bracket 221 of the pressing assembly 22, and the mounting bracket 221 is provided with a cutting groove 2212.

[0039] Positioning of the cutting blade 33: The cutting lifting motor 32 drives the cutting blade 33 to descend, so that the tip of the cutting blade 33 is close to the edge of the laminated glass (usually 1-3 mm away from the edge), ensuring accurate cutting position.

[0040] Cutting execution: The cutting track 31 (such as linear guide 211) drives the cutting motor to move along the cutting groove 2212, and the cutting blade 33 at the output end of the cutting motor cuts along the edge of the glass. Because the film is taut, the cutting blade 33 can cleanly and neatly cut the film, with a straight and smooth cut, without burrs or tears.

[0041] Mechanism reset and glass output: Cutting complete: After the cutting blade 33 moves to the end point, the cutting lifting motor 32 lifts the cutting blade 33, and the cutting mechanism 3 resets.

[0042] Clamping Release: The lifting motor 225 of the film clamping mechanism 2 drives the pressing plate 226 to rise, releasing the film. At the same time, the drive source 213 drives the carrier plate 212 and the pressing assembly 22 to move inward (towards the center of the glass) and return to the initial position.

[0043] Glass output: Roller conveyor 1 restarts, transporting the cut laminated glass to the next process (such as curing or packaging), and the unit is ready to process the next piece of glass.

[0044] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
