Description

one

The invention relates to a technique for manufacturing laminated glazing products glued using liquid materials hardening in the process of bonding, and is applicable in the case of gluing glasses having 5 identical sizes or different thicknesses.

A device for gluing glasses with liquid hardening materials is known, which contains process glasses, a sealing rubber tube and clamps with screws 1.

The disadvantages of this device are the low quality of the products and the laboriousness due to the fact that the technological glasses 15 are rigidly attached to the glasses to be glued, and after finishing the gluing, the technological glasses are removed.

Closest to the invention is a device for riveting a multilayer 20 materials, comprising a housing, an upper and lower frame, a sealing ring, an elastic chamber filled with a gas, and a means for filling the icing of the package with an adhesive material 2.25

In this device, the role of a process glass, rigidly connected to the glass to be glued, is performed by a frame, the configuration of which corresponds to the configuration of the glass. Glass connects with 30

frame using movable retainers. The junction between the glass surface and the frame is sealed with an elastic chamber. The cavity of the bag (and the space between the glued glasses) is decoupled with a rubber tube. When assembling a package, a tube is installed between the technological element (frame, technological glass) and one of the glasses to be glued together (by gluing products with a shelf), or between two technological elements. At the same time, a tube installed between the glasses or technological elements prevents mutual convergence of the glasses to be glued (the limited replacement of 1 glasses is allowed due to the elastic properties of the rubber).

The movable retainers are in the bonding layer for the entire period of hardening of the bonding material.

The disadvantage of this device is the presence of retainers in the bonding layer during the curing of the bonding material, leading to the formation of voids around which the gluing of multi-layer glazing products occurs. In addition, the use of retainers and a chamber that exerts pressure on the outer surfaces of the glass being glued, leads to deformation of these glasses, which is the reason for the appearance of significant optical distortion in glazing products.

Build packages in known devices has considerable complexity.

The purpose of the invention is to improve the quality of products and reduce the complexity of gluing.

This is achieved by the fact that the device for gluing multilayer glazing products with liquid hardening materials, comprising a corus, a pilot ring and an elastic spacer chamber filled with gas, and a means for filling the package cavity with a liquid hardened material, which is provided with elastic pins; between the casing and pilot ring, and above them are installed with the possibility of moving the pins and means for pouring the cavity of glassware, made in the form of a tube.

FIG. 1 shows the device, a section (after filling the cavity of the bag with a liquid adhesive material); in fig. 2 - the same, one of the stages of building packages in the device.

The device comprises a housing 1 and a top cover 2, which are interconnected by a hinge. The final fastened top cover on the body is bolted.

In the groove formed by the protrusion of the housing and the bottom cover 3, a spacer chamber 4 is placed, the pressure from which is transmitted to the sealing ring 5 mounted on the ends of the glued glasses 6 and 7.

Spacer pins 8 and a filling tube 9 are placed in guides located in the thickening of the housing. The spacer pins serve to fix the mutual position of the glued glasses during package assembly when there is no compressed gas in the spacer chamber. When the chamber is filled with compressed gas, the auxiliary supports are removed from the cavity of the bag. In this case, the presence of any retainers in the package cavity is not required, since the friction that occurs between the end surfaces of the glued glasses and the sealing ring prevents the blanks from coming together. The filler tube is removed after filling the cavity of the bag with a bonding material.

The assembly of the product to be glued (package assembly) in the device being described and produced in the following order.

On the supporting surface of the body stack glass 6 (Fig. 2). At the same time, at the end of the glass they pull a sealing

ring. Place spacer pins on the glass surface. The ca. room at the location and the stops are deformed, and the sealing ring is bent. Similarly, install and fill the tube. On the spacer pins impose a glass of 7, pull the seal ring on its end. Install the EI1Zhnuyu cover, fastened it with bolts. Into the spacer chamber

subcompact compressed gas. Auxiliary supports removed from the cavity of the package. The top cover is fastened, thereby setting the required thickness of the product. Through the filling tube, the cavity of the bag is filled with adhesive material, after which the tube is removed, and the camera, straightening, presses the pilot ring around the entire perimeter of the product, completely sealing the sealing layer.

After the bonding material has hardened, compressed gas is removed from the spacer chamber, the top cover is removed and the glued product is removed. The absence of retainers in the bonding layer allows one to get rid of voids, which are stress concentrators and which result in sticking during operation. The absence of a camera mounted on the outer surface of the glass reduces

absolute, optical distortion twice (due to the reduction of glass deformation).

Tests have shown that the laboriousness of assembling a package when using the described device is reduced by five times.
