Description

Technical Field

[0001] This application relates to the field of glass processing equipment technology, and in particular to an edge sealing device for laminated glass. Background Technology

[0002] Because the edges of laminated glass come into contact with air, moisture in the air can cause air bubbles to form at the edges, affecting not only the stability of the connection between the glass layers but also the aesthetics. Existing technologies can reduce the formation of air bubbles by sealing the edges of the laminated glass. However, current sealing methods often involve placing a frame with a sealing layer over the edges of the laminated glass, which alters the original shape of the edges. Another method involves applying adhesive to the edges of the laminated glass, but this method requires the glass to be laid flat and then applied with a movable adhesive applicator. Since the sealant has weight and is somewhat fluid when freshly extruded and not yet cured, it tends to deviate from its original application position after application, resulting in problems such as uneven application and incomplete sealing. Summary of the Invention

[0003] The purpose of this application is to provide an edge sealing device for laminated glass that allows for more stable application of sealant.

[0004] To achieve the above objectives, this application provides an edge sealing device for laminated glass: comprising two parallel guide assemblies, the main body of each guide assembly being a guide rail, each guide rail being provided with a movable gripping mechanism, the two gripping mechanisms being symmetrical to each other, each gripping mechanism including a sliding mechanism that slides with the guide rail, a lifting drive being fixedly connected to the sliding mechanism, a translation drive being fixedly connected to the movable end of the lifting drive via a mounting bracket, a rotation drive being fixedly connected to the movable end of the translation drive, a coaxial turntable being fixedly connected to the output end of the rotation drive, the axis of the turntable being horizontal, a suction cup being provided on the end face of the turntable facing away from the rotation drive, the end faces of the suction cups on the two turntables being opposite to each other, and a sealant application assembly being fixedly connected above the guide assemblies via a fixed frame, for uniformly and continuously applying sealant to the edge of the laminated glass.

[0005] As a preferred embodiment, each of the guide components includes two parallel guide rails, and the sliding mechanism has a guide through hole that extends through the side, through which the guide rails pass, forming a plug-in structure that is not easily disengaged.

[0006] As a preferred embodiment, the surface of the guide rail is provided with straight toothed grooves, the sliding mechanism contains a motor and a reducer, and the output end of the reducer is fixedly connected to a gear, which is suitable for meshing with the straight toothed grooves of the guide rail to ensure position control accuracy.

[0007] As a preferred embodiment, the bottom of the sliding mechanism has a protruding support plate, on which two lifting drives are fixedly connected. The movable ends of the two lifting drives are jointly fixedly connected to the mounting frame, which can effectively prevent the mounting frame from deflecting and give the mounting frame better lifting stability.

[0008] As a preferred embodiment, the mounting bracket also fixes two of the translation drives, and the output ends of the two translation drives are simultaneously fixedly connected to the rotary drive to share the bending stress of the rotary drive and ensure the translational stability of the rotary drive.

[0009] As a preferred embodiment, the lifting drive uses an electric telescopic rod, the translation drive uses a cylinder, and the rotation drive uses a structure combining an electric motor and a reducer, which has high angle control accuracy.

[0010] As a preferred embodiment, the fixed frame includes a crossbeam, with an extrusion head fixedly attached to the center of the crossbeam, and a configuration platform fixedly connected to the side of the crossbeam. A storage and heat preservation tank is provided on the configuration platform for storing a sealant with good flowability.

[0011] As a preferred embodiment, the two ends of the crossbeam are fixedly connected to the uprights via bridging plates, and the lower end of the uprights is fixedly connected to the end of the guide rail via a limiting plate. In this way, the horizontal projection position of the glue applicator on the guide rail will remain stable, which facilitates the editing of the position control program.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a suction cup structure that can be lifted, translated and rotated, the laminated glass can be translated vertically and rotated at the same time. The sealant applied to the edge of the laminated glass always flows along the gap between the glass layers, which effectively reduces the problem of incomplete sealing caused by the sealant deviating from the original coating position due to fluidity and gravity.

[0014] (2) The position of the glue applicator and the position of the glue outlet of the extrusion head remain unchanged in this design. Only the gripping mechanism moves between the guide component and the fixed frame with the laminated glass. The probability of collision with other items during the sealing and glue application process is smaller, so the processing process is safer. Attached Figure Description

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5 The edge sealing device for laminated glass shown includes two parallel guide components 1. The main body of the guide component 1 is a horizontal guide rail 101. Each guide component 1 includes two parallel guide rails 101, which can provide more stable guiding constraints for the mating moving parts.

[0026] Each guide rail 101 is equipped with a movable gripping mechanism 2 for lifting the laminated glass and adjusting its angle. Since there are two sets of guide rails 101, there are also two gripping mechanisms 2 on each guide rail 101. The two gripping mechanisms 2 are symmetrical to each other. The laminated glass is located between the two gripping mechanisms 2 and can be gripped by both gripping mechanisms 2 at the same time. Each gripping mechanism 2 includes a sliding mechanism 210 that slides with the guide rail 101. The sliding mechanism 210 has a guide hole 211 that passes through the side for the guide rail 101 to pass through. The surface of the guide rail 101 has a straight tooth groove. The sliding mechanism 210 contains a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is fixedly connected to a gear that meshes with the straight tooth groove of the guide rail 101, which can effectively ensure the position control accuracy of the sliding mechanism 210 when sliding relative to the guide rail 101.

[0027] A lifting drive 202 is fixedly connected to the sliding mechanism 210. The bottom of the sliding mechanism 210 has a protruding support plate 212 facing outwards. Two lifting drives 202 are typically fixedly connected to the support plate 212. The lifting drives 202 are electric telescopic rods, and both work synchronously under the control of an electronic system. The movable ends of the lifting drives 202 are fixedly connected to translation drives 204 via a mounting bracket 203. In effect, the movable ends of both lifting drives 202 are fixedly connected to the mounting bracket 203. The mounting bracket 203 is also fixedly connected to two translation drives 204, which are cylinders. The two cylinders work synchronously under the control of a pneumatic system. The movable ends of the translation drives 204 are fixedly connected to a rotary drive 205. The output ends of the two translation drives 204 are simultaneously fixedly connected to the rotary drive 205. The rotary drive 205 adopts a structure in which a motor and a reducer cooperate. The motor drives the reducer, and the output end of the reducer is the output end of the rotary drive 205. The output end of the rotary drive 205 is fixedly connected to a coaxial turntable 206. The axis of the turntable 206 is horizontal. The end face of the turntable 206 facing away from the rotary drive 205 is provided with suction cups 207. There are several suction cups 207. These suction cups 207 are arranged equidistantly around the axis of the turntable 206. These suction cups 207 and the translation drives 204 share a pneumatic control system. The only difference is that the output ends are connected differently. The end faces of the suction cups 207 on the two turntables 206 face each other, facing the two sides of the vacuum glass.

[0028] Above the guide assembly 1, a glue applicator 4 is fixedly connected via a fixed frame 3 to seal the gap between the glass edges. The fixed frame 3 includes a horizontal beam 301, with a glue extrusion head 401 fixed in the center of the beam 301, which can directly adhere to the edge of the laminated glass. A configuration table 302 is fixedly connected to the side of the beam 301, and a glue storage and heat preservation tank 402 is provided on the configuration table 302. The adhesive in the glue storage and heat preservation tank 402 has good fluidity. After being extruded from the end of the glue extrusion head 401, it will quickly cool and solidify upon contact with air. Vertical supports 304 are fixedly connected to both ends of the beam 301 via bridging plates 303. The lower end of the supports 304 is fixedly connected to the end of the guide rail 101 via a limiting plate 102, which restricts the position of the glue applicator 4 above the guide rail 101.

[0029] Working principle: During operation, the laminated glass first enters between the two guide components 1 via the conveying mechanism. When the two turntables 206 are in the center of the laminated glass, the translation drive 204 is quickly activated, causing the suction cup 207 to contact the laminated glass. The laminated glass is obstructed and cannot continue to follow the conveying mechanism. The system then extracts the air from the suction cup 207, creating a negative pressure. At this point, the laminated glass is tightly suctioned. Immediately, the lifting drive 202 is activated, lifting the laminated glass away from the upper surface of the conveying mechanism and bringing the upper edge of the laminated glass into contact with the lower end of the extrusion head 401. Subsequently, the suction mechanism inside the extrusion head 401 extracts the adhesive from the adhesive storage and insulation tank 402 and applies it to the gap between the glass edges. At the same time, the sliding mechanism 210 is activated, moving the laminated glass horizontally to evenly apply the adhesive to the gap between the glass edges. Because the edges of laminated glass are generally rounded, when the extrusion head 401 moves to the corner of the laminated glass, the lifting drive 202 and the rotary drive 205 work synchronously to adjust the angle of the laminated glass and ensure that the extrusion head 401 contacts the edge of the laminated glass, continuously applying glue to form a continuous sealing ring. When the rotary drive 205 completes one revolution, the extrusion head 401 will coincide with the initial contact position of the laminated glass. At this time, a complete sealing structure is formed around the edge of the laminated glass. Finally, the movable end of the lifting drive 202 moves down until the bottom edge of the laminated glass contacts the upper surface of the conveying mechanism again. The pneumatic system returns high-pressure gas to the suction cup 207, causing the suction cup 207 to detach from the laminated glass. The laminated glass with its sealed edges has no obstruction and will move forward with the conveying mechanism to enter the next process.
