Technical Field

The utility model belongs to the technical field of building materials, and relates to a gluing mechanism for producing a honeycomb aluminum plate.

Background

The aluminum honeycomb plate is an application of aviation and aerospace materials in the field of civil buildings. The panel is mainly made of high-quality 3003H24 alloy aluminum plates or 5052AH14 high-manganese alloy aluminum plates. The core material adopts a hexagonal 3003 type aluminum honeycomb core, the thickness of an aluminum foil is 0.04-0.06 mm, the side length is 5-6 mm, the forming of the front and back surface skins is completed by adopting a rolling forming technology, the edge folding is carried out by full-automatic machine equipment, and the front and back surface skins are tightly occluded on the installation edge. Due to the high heat conduction value between the aluminum skin and the honeycomb, the expansion with heat and contraction with cold of the inner aluminum skin and the outer aluminum skin are synchronous; the honeycomb aluminum skin is provided with small holes, so that gas in the plate can flow freely, and the slidable mounting buckle system cannot cause structural deformation when expanding with heat and contracting with cold, so that extremely high flatness can be ensured; adopting adhesive glue: the double-component polyurethane high-temperature curing adhesive is formed by compounding a full-automatic honeycomb plate compound production device through pressurization and high temperature, and overcomes the brittleness problem of the bonding layer of the conventional honeycomb plate. The dense honeycombs mutually constrained are like a plurality of small I-shaped beams, and can disperse and bear pressure from the direction of the panel, so that the panel is stressed uniformly, and the panel can still keep high flatness in a large area. Two sides are adopted for installation, and mechanical damage is avoided.

The aluminum honeycomb panel is 1/5 of the same thickness and same face building block panel weight, 1/6 of glass and 1/7 of aluminum, thereby greatly reducing the building load and the construction cost, as the middle interlayer contains a large amount of air, the building block panel can insulate sound (the air sound insulation can reach 30dB), insulate heat (the thermal resistance can reach 0.02 (square meter. K/W)), has no combustible substance, has the fire-proof grade reaching B1 grade, is waterproof, moistureproof and has no harmful gas release, has large specific strength of unit mass, high specific rigidity (the structural rigidity is 1.7 times of rib type), is not easy to deform, completely overcomes the defects of deformation, middle collapse and the like of other decorative panels when the single block area is large, can be cut edgefolds at will, the surface coating can ensure the product life to be more than 30 years, the surface of the aluminum honeycomb panel has extremely high flatness, and the anti-seismic performance is only one eighth of the specific gravity of the glass curtain wall; the standard part with the thickness of 22mm has the load of more than 700 kilograms of force when the standard part is simply supported by 1 meter and has the deflection of 10 mm. After the surface is treated by fluorocarbon resin with strong corrosion resistance, the coating can be widely applied to the decoration of curtain walls, roofs, large-scale door signs, interior walls and the like of buildings. Aluminum honeycomb panels have been widely used for exterior wall decoration of buildings due to their advantages of light weight, high strength, high rigidity, etc. The honeycomb sandwich panel with the same rigidity weighs only 1/5 for aluminum and 1/10 for steel.

Three components of the aluminum honeycomb panel are generally assembled manually, and especially, the feasibility of online continuous production is greatly restricted by factors such as long curing time (tens of minutes to hours are different) of the double-component polyurethane high-temperature curing adhesive, the need of maintaining the relative positions of the three components not to loosen in the press-fitting process, and the like.

The technical problem that this scheme can be solved and the effect that can reach as follows:

the bonding glue is high-temperature-resistant glue with low fluidity, only a reticular glue network consisting of adhesive tapes can be formed by gluing the aluminum frame 41 through the gluing mechanism 3, the complete coverage on the aluminum frame 41 cannot be formed, the existence of the bonding glue cannot be ensured at all the contact positions of the honeycomb net rack 42 and the aluminum frame 41, and further, if the glue network is not flattened, the bonding strength of the honeycomb net rack 42 and the aluminum frame 41 is influenced; in addition, in the conventional process, the back plate 43 needs to be glued separately, and in the scheme, the back plate 43 is close to and attached to the glued aluminum frame 41, so that the back plate 43 and the aluminum frame 41 are flattened by the glue, and the back plate 43 can be glued.

The conveyor belt 12 runs slowly, can operate the placement of the aluminum frame 41, the installation of the back plate 43 and the leveling of the honeycomb net rack 42 on line, and can ensure the laminating to be compressed until the bonding glue is cured, thereby realizing the continuous operation on line.

Air with certain pressure is injected into a sealed cavity formed by the positioning bottom box 16, the positioning top box 17 and the air film 22, the air uniformly acts on the upper surface of the back plate 43 through the air vent plate, uniform and stable pressure is applied on the back plate 43, and uniform pressing force among the back plate 43, the aluminum frame 41 and the honeycomb net rack 42 is ensured; because the positioning top box 17 has a certain longitudinal movable distance on the push rod of the hydraulic cylinder 18, the suction cup 21 can be separated from the back plate 43, the positioning top box 17 and the positioning bottom box 16 are sealed by the pressure of the hydraulic cylinder 18 at the moment, and the high-pressure air flow in the air film 22 is not enough to influence the sealing performance of the positioning top box and the positioning bottom box; in the traditional mode, a negative pressure mode is adopted to realize the sheet combination process, namely: utilize a vacuum bag to wrap up the backplate 43, aluminium frame 41 and the honeycomb rack 42 three of superpose, then carry out the evacuation to the vacuum bag, compress tightly the three through the negative pressure, can after the solidification of bonding glue, however, this kind of mode can cause the excessive condition of gluing of gap department of backplate 43 and aluminium frame 41, also can cause the condition that bonding glue flows in the small margin in the laminating cavity, still because of the production that the vacuum bag caused the substandard product is scratched easily to aluminium frame 41 edges and corners, consequently, the negative pressure mode is inferior to this scheme.

Beat gluey mechanism 3 and can beat gluey rifle 33 in-process continuous feed that removes, the bonding glue also conveniently adds.

This scheme working strength is little, online number is few, and a production line only needs two people, goes up aluminium frame 41 for one, and another settles backplate 43, and synchronous transfer chain is located panel transfer chain top, and is also reasonable relatively to the utilization in workshop space.
