Technical Field

The invention relates to a preparation method of a large composite material expandable space structural member, in particular to a continuous bonding method of an ultralong composite material strain energy rod.

Background

The development trend of the future aerospace detection technology is to be continuously approaching to the great sea of the solar system and other stars, and the spacecraft needs to complete the task, so two key problems need to be broken through urgently: (1) the large-scale of the composite material structure, such as the area of a satellite antenna reaching 600m2 magnitude and the area of a large solar sail of a propulsion mechanism reaching 1000m²Space solar power stations built in the future reach extremely large sizes; (2) the composite material structure hasThe deep space exploration spacecraft has the characteristics of folding and unfolding, and due to the limited carrying capacity, the deep space exploration spacecraft has to be light in weight, good in rigidity, small in folding volume and high in unfolding reliability. The spatial ultra-long strain energy rod (the length of a single strain energy rod is more than or equal to 50m) has the characteristics of large scale and light weight, simultaneously has the functions of intelligent folding and unfolding, and is an ideal structure for breaking through the key problems.

The composite material strain energy rod belongs to a continuous super-long structure, has a single length of more than 50m, and is formed by symmetrically gluing a pair of strain energy rod valves. The traditional composite material gluing method comprises the steps of firstly manually polishing, cleaning a gluing surface, gluing, realizing gluing by adopting a tool clamp with the same surface type as a product (whether a glue layer needs to be cured by an oven or an autoclave is determined according to process requirements), and finally finishing the product to a state required by design. The traditional bonding process can not only cause that the strain energy rod can not be flattened, coiled and folded finally due to various errors, but also can severely limit the product size by the space size, which obviously can not meet the bonding requirement of the ultra-long composite material strain energy rod. Therefore, a new method capable of avoiding error influence and breaking through space limitation must be developed to realize high-precision, high-reliability and high-efficiency preparation of the strain energy structure of the ultra-long composite material, so that technical reserve is provided for research of large-scale spacecrafts for deep space exploration in China.

Disclosure of Invention

The invention aims to provide a continuous bonding method of an ultralong composite strain energy rod, which solves the problem that the size of a bonded product is limited by space and improves the bonding precision, stability and efficiency of the strain energy rod.

The purpose of the invention can be realized by the following scheme:

on one hand, the invention provides a continuous bonding method of an ultralong composite strain energy rod, which comprises the following bonding steps:

s1, winding a pair of strain energy rod valves on two winding drums through a material discharging module, placing the winding drums on a material discharging shaft for discharging, and keeping the film in a straight state;

s2, stopping discharging when the valves in the flat state pass through the glue applying module, and applying glue to the corresponding glue bonding parts of the two valves;

s3, passing the straight valves after glue application through a pressurizing module, drawing the two valves into a flat plate mould, and keeping the pressurizing state to realize glue joint after positioning is completed;

s4, passing the strain energy rod which is glued and kept in a straight state through a winding module; and (4) winding the material receiving cylinder, and simultaneously discharging the material discharging modules to realize continuous splicing.

Preferably, the valve thickness is less than 0.3mm in step S1; the width deviation is less than 0.2 mm; the straightness is better than 0.5 mm; the diameter of the barrel is not less than 80 mm. The pair of strain-energy rod valves are equally long.

The thickness of the valve is less than 0.3 mm: according to earlier researches, the valve with the thickness of more than 0.3mm is difficult to flatten and curl due to the overlarge rigidity, and the requirement (the flattening and curling operation on the valve in the application) and the function required by the structure of the process method cannot be met. Width deviation below 0.2 mm: the uniformity of the glue width and thus the reliability of the structure in use (for example, the glue area suddenly changes to cause stress concentration) are affected. The straightness is better than 0.5 mm: firstly, the straightness difference can not meet the premise of the continuous automatic process method provided by the patent, and the smooth proceeding of the gluing is directly influenced; even if the gluing is realized, the poor straightness of the glued structure can affect the use reliability. The diameter of the charging barrel is not less than 80 mm: the valve is of an elastomeric construction (comparable to a steel tape), and a too small crimp diameter can permanently damage the valve.

Preferably, in step S1, two rolls of valves are placed on the discharging shaft in a centered state; the discharging module is provided with a guide roller and a pair roller, and the discharged valve is restrained to keep a straight state through the guide roller and the pair roller. The module has a deviation rectifying function, and ensures that the two material cylinders are coplanar on a neutral surface through the limiting block, so that the two valves are pulled out, and the follow-up operation of other modules is ensured to have high position precision.

Preferably, a polishing module is arranged behind the discharging module, and the part of the gluing surface is polished. The polishing module is provided with a polishing head, the number of the polishing head sand meshes is 120-600 meshes, and the polishing pressure is 0.05-0.2 MPa. The grinding process compresses and fixes the area nearby except the gluing surface, and ensures that only the gluing area is ground by the grinding tool. The mesh number of the sand is 120-600 meshes: the valve is easy to be worn by the sand grains when the sand grains are too thick, and the grinding efficiency is low and the grinding is not in place when the sand grains are too thin. The grinding pressure is 0.1 MPa-0.2 MPa: the valve is easy to be worn through when the pressure is too high, and the grinding efficiency is low and the grinding is not in place when the pressure is too low.

Preferably, a cleaning module is provided between the glue module and the sanding module. The cleaning module cleans the polished adhesive surface part, and cleans the adhesive surface part to a state of adhesive joint through cleaning.

Preferably, the module peripheral dust cover is cleaned. And during cleaning, the brush and the dust collection head are used for removing polishing dust on the valve surface. The glued joint surface is wiped repeatedly by gauze stained with cleaning agent, and then cleaned by clean gauze to finish the cleaning of the glued joint surface.

Preferably, the sizing process of step S2 may use a glue film or an adhesive. The thickness of the adhesive film is less than 0.15mm, the width deviation is less than 0.2mm, and the curing time is 5-15 min; the lowest viscosity of the adhesive is more than 15000 mPa.s. The thickness of the adhesive film is less than 0.15 mm: firstly, in the process, an adhesive film or an adhesive is expected to be pressed and not stretched as much as possible (the formula of the adhesive film or the adhesive is changed to improve the lowest viscosity of the adhesive film or the adhesive); ② the adhesive film or adhesive may be pressed and extended during the gluing process. In the case of the first condition, the adhesive film or the adhesive is not stretched under pressure, and if the adhesive film or the adhesive is thick, the thickness of the bonding surface of the strain energy rod after the bonding is finished is large, so that the curling performance is influenced; in case of the situation II, the extension degree of the adhesive film or the adhesive can be reduced by reducing the thickness of the adhesive film or the adhesive, if the adhesive film or the adhesive is pressed and extended in the curing process, the width of the adhesive joint surface is larger than the theoretical width and is uneven, so that the structure deviates from the design value, and the reliability of the structure in use is influenced. Width deviation below 0.2 mm: the uniformity of the glue joint width is affected, and the reliability of the structure in use is further affected. The minimum viscosity of the adhesive is more than 15000mPa & s: the degree of pressure expansion during the curing process of the adhesive is reduced as much as possible.

Preferably, the adhesive is a two-component adhesive. After mixing, the lowest viscosity is more than 15000 mPas.

Preferably, the surface roughness of the flat mold in step S3 is better than ra1.6, and the flatness is better than 0.1 mm. The pressure of the flat plate die acting on the strain energy rod in the flattening state is 0.1-0.3 Mpa. The flat mold has a heating function. The surface roughness is better than Ra1.6, and the planeness is better than 0.1 mm: the requirements on the surface roughness and the flatness of the die are to ensure the surface quality and the thickness uniformity of the glued product. The pressure is 0.1-0.3 MPa: the pressure is too low, and the cementing performance is poor due to insufficient cementing; the pressure is too high, and the adhesive layer can excessively extend to cause the adhesive layer to be too thin and uneven in width.

The upper die of the flat die can be opened and closed up and down, a release agent is coated on the surface of the flat die, and the pressure of the flat die acting on the strain energy rod in the flattening state is 0.1-0.3 MPa. The mould can be pressurized and heated according to the process requirement, the temperature of the mould is less than 100 ℃, and the gluing temperature is at least 80 ℃ lower than the service temperature of the valve resin base material.

Preferably, a cutting module is provided after the pressing module. The cutting module cuts the boundaries of the two sides of the strain energy rod to the designed size. In the cutting process, the part area within the design boundary is compacted by a clamp, and an ultrasonic auxiliary cutting method is adopted, so that the damage of the cutting process to the structure is reduced.

Preferably, a traction module is arranged in front of the winding module. The strain energy rod which is well glued is pulled to advance under the action of the pulling force of the pulling module, and the strain energy rod continues to keep a straight state and is wound through a material coil.

Preferably, the winding module is provided with a pair of rollers in step S4, and the strain energy rod is restrained by the pair of rollers to keep a straight state. The strain energy rod is furled through the winding module, and the diameter of the material collecting barrel is not less than 150 mm.

When a flat plate die of the pressurizing module is opened and the strain energy rod is pulled to advance, only the unreeling module discharges materials, and the reeling module receives materials; in the process of pressing the flat plate mould of the pressurizing module, the polishing module polishes the gluing surface, the cleaning module cleans the polished part, the gluing module coats adhesive or attaches an adhesive film on the gluing surface, and the module is cut. Through the steps, a gluing cycle is completed, and continuous gluing of the strain energy rod is realized by continuously repeating the cycle.

On the other hand, the invention also relates to a device for continuously gluing the ultra-long composite material strain energy rod, which sequentially comprises a material placing module, a polishing module, a cleaning module, a glue applying module, a pressurizing module, a cutting module, a traction module and a winding module; the discharging module comprises a winding drum placed on the material shaft, a guide roller and a pair roller, wherein the valve is discharged from the material barrel and sequentially passes through the guide roller and the pair roller; the polishing module is provided with a polishing head; the glue applying module comprises a glue scraping head or a press roller; the pressurizing module is provided with a heatable flat plate die; the winding module is provided with a material cylinder for receiving materials through a pair roller by a strain energy rod in a flattening state.

The strain energy rod is formed by symmetrically gluing two valves, and can be flattened, curled and folded due to the characteristic of ultrathin elasticity, and the designed section can be recovered after the strain energy rod is unfolded. The process mentioned in this application makes use of this feature: the valve is rolled, the valve is elastically deformed, the cross section is changed into a straight state, and the bonding is carried out in the straight state, so that the bonding method is simplified, the bonding efficiency and quality are improved, and the problem that the strain energy rod cannot be flattened and curled after bonding due to the fact that the valve is weak in rigidity and cannot be accurately positioned and tooling manufacturing errors in the in-situ bonding process can be solved (the in-situ bonding is bonding according to a design state, so that the symmetrical valve is required to be completely positioned at a theoretical position, and the requirement on position precision is extremely high).

Compared with the prior art, the invention has the following beneficial effects:

the method adopts a continuous flattening and gluing method to replace the traditional manual gluing, not only solves the problem that the in-situ gluing cannot be flattened and wound subsequently due to various errors, but also breaks through the limitation of space size, integrates the procedures of flattening, polishing, cleaning, gluing, pressure gluing, cutting and the like, and realizes the high-precision, high-reliability and high-efficiency preparation of the ultra-long composite material strain energy structure.
