[0038] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the examples can be practiced without these specific details.

[0039] With the continuous progress of technology and the intensification of market competition, the mass production, low-cost, and short-cycle commercial satellite production model has become the key for aerospace enterprises to improve their competitiveness. As the main structure of the satellite, the production and manufacturing method of the honeycomb panel urgently needs to be updated and iterated.

[0040] As Figure 1 shown, the manufacturing process method of the honeycomb panel of the satellite main structure in the prior art:

[0041] Process 1: Since the conventional thickness of the honeycomb panel skin is 0.3 mm and its rigidity is poor, making it impossible to position the embedded parts, a 3-mm-thick positioning plate is added to assist in positioning. This process requires the design and manufacture of the positioning plate, which is time-consuming and costly.

[0042] Process 2: Since the honeycomb panel itself has weak rigidity, the flatness of the formed panel depends on the flatness of the platform. The platform is generally made of cast aluminum after precision machining of the plane. After the existing honeycomb panel embedded parts are positioned on the tooling plate, they need to be transported to this platform. The product is easily damaged during the transportation process, and this platform has a single function and high processing costs.

[0043] Process 3: Since hot pressing cans or ovens are used for pressurization, a vacuum bag needs to be made to achieve differential pressure pressing. The auxiliary materials required for making the vacuum bag are costly, and the production time is usually long, greater than 1 h.

[0044] Process 4: The product is pressurized through the air pressure difference, and the product is heated by the heating wire and the circulating hot air of the fan. The whole box or tank needs to be heated, and the heat transfer efficiency is low, resulting in high time and energy costs.

[0045] In summary, the honeycomb panel is moved back and forth, resulting in problems such as long time consumption and high processing costs.

[0046] Based on this, the embodiments of this specification propose a new solution for an integrated adsorption heating platform, which is applicable to the manufacture of the honeycomb panel of the satellite main structure. A new type of honeycomb panel forming heating platform with a vacuum adsorption function is realized. Through a clever structural design, an integrated adsorption and heating platform is achieved, and then the press can be borrowed for pressurized forming, replacing the single function of the traditional aluminum platform. During the honeycomb panel forming process, there is no need for a tooling positioning plate, no need for external equipment heating (such as heating cans / thermal ovens in the prior art), and no need to move the honeycomb panel.

[0047] The following describes the technical solutions provided by the embodiments of this application with reference to the accompanying drawings.

[0048] As Figure 2 shown, looking down on an integrated adsorption heating platform of this application, it includes a platform body 0 and an adsorption cover plate 2; the platform body 0 is the main structure of the platform. The platform body 0 is a whole metal plate with a certain thickness, such as an aluminum plate; the platform body 0 is provided with an oil passage 1, a heat insulation groove 6, an air flow passage (not shown, but the air flow passage is arranged between adjacent oil passages and is located outside the heat insulation groove), a sealing ring 5, a first quick-change joint (such as an oil passage quick-change joint 7), a second quick-change joint (such as a pneumatic quick-change joint 8), and an oil heat passage plug 3.

[0049] The oil passage, the air flow passage, the heat insulation groove, and the sealing ring are arranged inside the platform body.

[0050] The oil passage is provided by drilling along an edge of the platform body, such as from one side, and the drilling penetrates through to the opposite side. The oil passage is used for heating. In some embodiments, the distance from the oil passage to the lower surface of the platform body itself is less than its distance to the platform adsorption surface.

[0051] Among them, the oil passage is integrally processed with the platform body. The oil passage is formed by directly opening holes on the platform body, which reduces the processing procedures and material waste, thereby reducing the overall processing cost. The integral processing also reduces the assembly link, avoids the sealing problems and structural strength problems caused by assembly errors, and improves the overall quality and reliability of the platform. The integrally processed oil passage reduces the heat loss during the heat transfer process, improves the heating efficiency, and enables the platform to reach the preset temperature faster. The integral processing reduces the connecting components and interfaces, simplifies the structure of the platform, and reduces the complexity of maintenance and repair.

[0052] The air flow passage is arranged between adjacent oil passages 1. That is to say, the oil passage and the air flow passage are arranged at intervals to achieve the heat insulation effect. Without the heat insulation design, the gas in the air flow passage will also be heated; usually the heating temperature is 130 °C, then the gas in the air flow passage is heated to form a high-temperature air flow, and the heated gas is discharged to the outside from the air flow exhaust hole, which is not only not conducive to the safety of the staff, but also the discharged gas carries more heat, resulting in low heating efficiency.

[0053] Heat insulation grooves 6 are arranged in the air flow passage, and the heat insulation grooves are used for isolating heat. Vent holes are arranged at both ends of the heat insulation groove along the arrangement direction. The vent hole connected to the air source at one end is the air inlet hole, and the other end is the air flow exhaust hole; vent holes of the same size are also arranged at the corresponding two ends of the air flow passage, one end is the air inlet hole, and the other end is the air flow exhaust hole.

[0054] The air flow passage is connected to the adsorption cover plate arranged above it, and a sealing ring 5 is arranged on the connection plane between the air flow passage and the adsorption cover plate (such as the stepped connection plane of the platform body), and the sealing ring 5 is used to prevent gas from flowing out.

[0055] The adsorption holes penetrate through the adsorption cover plate and the heat insulation groove, and the adsorption surface of the platform body is used to place the honeycomb board product; among them, the adsorption holes are like the black dots shown on the adsorption cover plate 2 and can be Φ2mm holes. The adsorption surface refers to the side of the platform body corresponding to the adsorption holes.

[0056] A first quick-change joint (such as an oil passage quick-change joint 7) is arranged on one side of the platform body, and the first quick-change joint is used to connect the oil passage to an external heating device (such as a mold temperature controller) of the integrated adsorption heating platform.

[0057] On one side of the platform body, a second quick-change joint (such as pneumatic quick-change joint 8) is provided, and the second quick-change joint is used to connect the air flow channel to an external gas source device of the integrated adsorption heating platform.

[0058] Along the arrangement direction of the oil circuit channel, on the other side of the platform body corresponding to the oil circuit channel, an oil heat channel plug 3 is provided, and the oil heat channel plug 3 is used to block the oil circuit.

[0059] Along the arrangement direction of the air flow channel, on the other side of the platform body corresponding to the air flow channel, an air flow exhaust hole (such as at the corresponding position of the pneumatic circuit silencer 4) is provided, and the air flow exhaust hole is used to discharge the gas flowing through the air flow channel; in some embodiments, a pneumatic circuit silencer 4 is provided at the air flow exhaust hole to reduce the noise effect when the gas is discharged.

[0060] In some embodiments, the arrangement directions of the oil circuit channel and the air flow channel are the same, such as arranged along the width direction of the integrated platform. In this way, the ends of the adjacent oil circuit channels connecting to the external heating device are distributed along the length direction of the integrated platform, that is, the long-side distributed independent heating oil circuit channels are adopted.

[0061] Wherein, when the second quick-change joint is connected to a gas source with a preset speed (such as generating high-speed gas by inputting 6Bar gas source), the gas flows to the adsorption holes during the flow in the air flow channel, so that a negative pressure is formed in the corresponding honeycomb panel product at the adsorption holes, and the adsorption holes are used to adsorb the honeycomb panel product, so that the honeycomb panel product maintains a flat surface according to the adsorption surface and avoids deformation;

[0062] And / or, when the first quick-change joint is connected to an external heating device (such as a mold temperature controller), the oil circuit channel is used to heat the honeycomb panel product placed on the adsorption surface.

[0063] In summary, the integrated adsorption heating platform of the present application realizes the adsorption function: based on the Bernoulli principle, a negative pressure structure form is invented, the platform surface is modularized, that is, adsorption holes with a diameter of Φ2mm are arranged on the upper surface of the through heat insulation groove and the adsorption cover plate. For example, by inputting 6Bar gas source to generate high-speed gas, a negative pressure is formed, so that the honeycomb panel product such as the panel is closely attached to the platform, solving the problem of panel flatness, and the modular layout also solves the adsorption problem of honeycomb panels of different sizes.

[0064] Realize the heating function: Use a mold temperature controller for heating. For example, the oil circuit channel is arranged along the long side of the integrated adsorption heating platform, and the heating channel can be modularized. It can heat small-sized products in a small range and large-sized products in a large range, improve the heating efficiency, and achieve the effect of energy saving and efficiency improvement.

[0065] Achieve heat insulation function: This platform is an integrated platform for adsorption and heating. The high-speed gas linear air flow channels and the heating oil channels are arranged at intervals. When the heating function is started, the air flow channels and the oil channels adopt a segmented (spaced) structure design. The inner wall of the air flow channels uses polyimide material (YS20) to isolate the problem of heat conduction caused by direct contact between pneumatic adsorption and heating in the oil channels.

[0066] In some embodiments, the upper surface of the heat insulation groove has the same size as the adsorption holes provided on the adsorption cover plate, and they are concentric adsorption holes; the adsorption holes are linearly distributed along the width direction of the platform body.

[0067] As Figure 2 shown, adsorption holes linearly distributed along the width direction of the platform body penetrate through the upper surface of the heat insulation groove and the adsorption cover plate. A fixed interval, such as an interval of 40 mm, is set between adjacent adsorption holes, and they are concentric adsorption holes on the upper surface and the adsorption cover plate, and the diameter of the adsorption hole is Φ2 mm.

[0068] In some embodiments, each of the oil channels is correspondingly provided with an oil quick-change joint, and each of the oil quick-change joints is used to heat the corresponding local oil channel according to the size of the honeycomb board product, so as to heat the area on the adsorption surface where the honeycomb board product is placed.

[0069] As Figure 2 shown, each of the oil channels 1 is correspondingly provided with an oil quick-change joint 7. In this way, each of the oil quick-change joints is used to heat the corresponding local oil channel according to the size of the honeycomb board product, so as to heat the area on the adsorption surface where the honeycomb board product is placed.

[0070] It should be noted that the oil channels are arranged along the width direction of the integrated platform. In this way, the ends of adjacent oil channels connecting to the external heating equipment are distributed along the length direction of the integrated platform, that is, the long-side distributed independent heating oil channels are adopted. If the adjacent oil channels are distributed along the short side of the integrated platform, the length of the oil path is too long and the heating area is large, which is not conducive to local heating. Compared with the short-side setting, the long-side distribution adopted in the present invention can heat different areas for products of different sizes, and the long-side distribution is beneficial to heating different areas and improving the heating efficiency.

[0071] In some embodiments, as Figure 2 shown, a plurality of (such as 5) air flow channels are correspondingly provided with a pneumatic quick-change joint 8, and each pneumatic quick-change joint is used to form a gas with a preset speed in the corresponding local air flow channels according to the size of the honeycomb board product, so as to form a negative pressure at the position corresponding to the adsorption holes in the local area where the honeycomb board product is placed, maintain a flat surface, and avoid deformation.

[0072] As Figure 2As shown, the oil circuit quick-change joint 7 can adapt to honeycomb panels of different sizes. When the size is small, only part of the oil circuit quick-change joints need to be connected between the mold temperature controller and the oil circuit channel, which plays a role in flexibly controlling the heating area, and the oil circuit quick-change joint has a plug-and-play effect. Similarly, the pneumatic quick-change joint 8 can adapt to honeycomb panels of different sizes. When the size is small, only part of the pneumatic quick-change joints need to be connected, which plays a role in flexibly variable adsorption, and the pneumatic quick-change joint has a plug-and-play effect. That is, the oil circuit conversion joint and the pneumatic quick-change joint start local areas on the integrated platform for heating / adsorption, playing a role in flexibly controlling heating / adsorption, and the corresponding oil circuit / pneumatic quick-change joints have a plug-and-play effect, further simplifying the structure but achieving better results. In some embodiments, the inner wall of the air flow channel is made of polyimide material, which can reduce the heating area and improve the heating efficiency. On the contrary, if there is no heat insulation groove set, the entire platform entity needs to be heated, while in the present invention, the heat insulation groove and the internal space are insulated, reducing the heating entity, reducing the heating area, and with the same heating power, the temperature rises faster. Combining the above embodiments, the inner wall of the heat insulation groove is made of polyimide heat insulation material, which has a heat insulation effect.

[0073] In some embodiments, the second quick-change joint includes a five-way joint, and a plurality of the five-way joints are arranged on the other side of the platform body.

[0074] As Figure 2 shown, the second quick-change joint includes a five-way joint 9, which is arranged on the other side of the platform body (such as Figure 2 the lower side of

[0075] In some embodiments, it further includes a pneumatic circuit silencer, which is arranged at the air flow exhaust hole, on the other side of the platform body, and is used to reduce noise when the gas is discharged. As Figure 2 shown, the pneumatic circuit silencer 4 is arranged on the upper side of the platform body as Figure 2 shown, and is used to reduce noise when the high-speed gas is discharged.

[0076] In some embodiments, one side surface of the platform body and the other side surface are symmetrically arranged along the width direction of the platform body.

[0077] In some embodiments, the size of the platform main body is 2600×1600×50 mm, the distance between the air flow channel and the oil circuit channel is 100 mm, the distance between two adjacent adsorption holes is 40 nm; the diameter of the adsorption hole is 2 mm.

[0078] For example, the integrated adsorption heating platform of the present application can be applied to honeycomb panel materials with a shape size within 2600×1600mm. Among them, for the processing of the platform body, if the material is 6061-T6; the quantity is 1; the shape size of the platform body is 2600×1600×50mm, and the oil passage 1 and the heat insulation groove 6 are processed. During the processing, stress relief treatment is carried out by aging.

[0079] For the processing of the adsorption cover plate, if the material is 6061-T6, the quantity is 10; the shape of the adsorption cover plate and the adsorption holes with a diameter of Φ2 are processed, as well as the features such as screwing connection with the platform body. During the processing, stress relief treatment is carried out by aging.

[0080] The polyimide heat insulation groove, that is, the processing of the heat insulation groove. If the material is YS20, the quantity is 10; the heat insulation groove and the adsorption holes with a diameter of Φ2 are machined by external cooperation. Assemble the above-mentioned parts as follows Figure 2 After assembly, for overall machining: After the assembly is completed, in order to meet the flatness requirements of the use plane, the surface needs to be overall machined to meet a roughness better than 3.2um; the flatness is better than 0.05mm within 100×100mm, and the overall flatness is better than 0.1mm.

[0081] Combined with the above embodiments, the present application also provides a method for manufacturing a honeycomb panel, which is applied to the manufacturing process of the honeycomb panel of the satellite main structure, and applies the integrated adsorption heating platform described in any one of the above technical solutions, including: placing the lower panel of the honeycomb panel with the glue film on the integrated adsorption heating platform, and starting the number of air flow channels, oil passage channels and adsorption cover plates according to the size of the honeycomb panel; connecting the gas source to the integrated adsorption heating platform through the second quick-change joint to form a negative pressure at the adsorption holes in the corresponding area where the honeycomb panel product is placed; connecting the mold temperature machine to the integrated adsorption heating platform through the first quick-change joint to heat the integrated adsorption heating platform to the first preset temperature, and placing the embedded parts, and the embedded parts are prevented from moving in position under the action of the viscosity of the glue film on the honeycomb panel; placing the honeycomb, foaming agent and upper panel on the lower panel in sequence, continuing to heat to the second preset temperature, pressing the honeycomb panel with the pressing plate of the press, and continuously heating until the curing temperature of the honeycomb panel, and forming the honeycomb panel after heat preservation and pressure holding according to the curing system of the honeycomb panel.

[0082] Specifically, the process of forming a honeycomb panel using this integrated platform:

[0083] a) Place the lower panel (with glue film) of the honeycomb panel on this integrated platform, and start the adsorption function according to the size of the honeycomb panel. The principle of the negative pressure air path in this adsorption function is the Bernoulli principle;

[0084] b) Start the heating function: The mold temperature controller heats the oil to 40 to 50 °C to make the adhesive film on the panel have a certain viscosity. After placing the embedded parts, the embedded parts will not be displaced during transportation under the action of the adhesive film viscosity. In other words, the preheating function before placing the embedded parts is realized to prevent the relative displacement of the embedded parts during transportation.

[0085] As Figure 3 shown, compared with the existing adhesive assembly process, the present application realizes a new process method for positioning the process boss of the embedded parts, replacing the existing process method of using tooling for positioning and locking with pins and screws. The use of this function saves tooling design and tooling manufacturing; at the same time, the pin and screw locking is cancelled, canceling the locking device and the multi-axis bottom locking device for the later automated assembly production line of the embedded parts, greatly reducing the manufacturing cost of the automated equipment.

[0086] c) Place the honeycomb, foaming glue, and upper panel, transport them to the press platform, start the heating function to preheat to 60 °C, the press pressure plate presses the honeycomb panel, and at the same time, the temperature continues to rise until the curing temperature of the honeycomb panel is reached. After keeping the temperature and pressure according to the curing system, the product is formed.

[0087] It should be noted that the honeycomb panel manufacturing materials are placed on the integrated adsorption heating platform without the need for back-and-forth handling and movement during the manufacturing process.

[0088] During the pressing process of the present application, only an ordinary press is required for pressing, that is, there is no special requirement for the cost of the pressing equipment, which has practicability and low equipment cost.

[0089] In some embodiments, the number of air flow channels, oil flow channels, and adsorption covers is determined according to the size of the honeycomb panel, including: if the size of the honeycomb panel is the size of a part of the integrated adsorption heating platform, the number of air flow channels, oil flow channels, and adsorption covers corresponding to the honeycomb panel product placement area is started; if the size of the honeycomb panel is the same as the size of the integrated adsorption heating platform, the number of all air flow channels, oil flow channels, and adsorption covers on the integrated adsorption heating platform is started.

[0090] In summary, the integrated adsorption heating platform designed in the present application creates a new integrated adsorption heating function platform for the production design of the honeycomb panel of the satellite main structure. Compared with Figure 1 the existing technology, the present application does not need to add a 3-mm-thick positioning plate for auxiliary positioning, etc., and solves the flatness problem of the honeycomb panel material such as the panel (0.3 mm thick) during the assembly process and transportation process.

[0091] As Figure 3As shown, compared with the existing adhesive assembly process, the present application realizes a new process method for positioning the process boss of the embedded part, replacing the existing process method of using tooling for positioning and locking with pins and screws. The use of this function saves tooling design and tooling manufacturing; at the same time, the pin and screw locking is cancelled, eliminating the locking device and the multi-axis bottom locking device for the later automated assembly production line of the embedded part, greatly reducing the manufacturing cost of the automated equipment.

[0092] The heating function of the present application does not require equipment such as autoclaves, hot ovens, and hot presses to provide heat sources as in the existing technology, saving equipment costs; it can also realize the preheating function before placing the embedded part, preventing relative displacement of the embedded part during transportation. Further, a modular design of independent heating oil channels is distributed along the long side of the integrated platform (for example, the integrated platform is usually rectangular, with the platform outer dimensions of 2600×1600mm, and the oil channels are arranged along the width direction of the integrated platform, and adjacent oil channels are distributed along the length direction of the integrated platform, that is, the oil channels are arranged on the 2600 side, so that the holes of the oil channels are set to be 1600 deep in the width direction, making it easier to machine the holes of the oil channels.

[0093] Adjacent oil channels are distributed along the length direction of the integrated platform, that is, the holes of the oil channels are distributed along the long side, which can realize local heating and heat different areas for products of different sizes. If adjacent oil channels are distributed along the short side of the integrated platform, the oil path will be too long and the heating area will be large, which is not conducive to local heating. Compared with heating different areas for products of different sizes by distributing along the long side, and the heating element directly contacts the product, the heating efficiency is improved.

[0094] The heat insulation function of the present application enables the adsorption and heating functions to work simultaneously on the same platform without mutual influence, not only improving the heating efficiency, but also reducing the cooling of the pneumatic channel and the cooling of the integrated platform, etc. Among them, if the oil channel and the air flow channel are not spaced, usually the heating temperature is 130°C, which will cause the gas in the air flow channel to be heated. If there is no spacing, the temperature of the heated gas is relatively high and is discharged to the outside from the pneumatic circuit muffler, which is not conducive to personnel safety. At the same time, the gas takes away heat, resulting in low heating efficiency. Therefore, a heat insulation groove is set to reduce the heating area and improve the heating efficiency. On the contrary, if the heat insulation groove is not set, the entire platform entity needs to be heated, while the present invention sets the heat insulation groove and the internal space is insulated, reducing the heating entity and the heating area, and with the same heating power, the temperature rises faster.

[0095] The present application changes the existing honeycomb panel forming process method in the honeycomb panel production and manufacturing mode, realizing the whole process of honeycomb panel adhesive assembly and curing (such as the existing process 4, pressure curing) on one platform, reducing problems such as deformation during product handling and interference protrusion of the embedded part, and improving product quality.

[0096] A new process method that improves heating efficiency, eliminates bonding tooling, and does not require other heating equipment (such as heating tanks / thermal ovens in the existing method) has achieved the effects of shortening the production cycle of honeycomb panels and reducing production costs.

[0097] For the various embodiments in this specification, the same or similar parts can be referred to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the product embodiments described later, since they correspond to the methods, the descriptions are relatively simple, and the relevant parts can be referred to the partial descriptions of the system embodiments.

[0098] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
