Heating curing closing mold for glue joint of middle wing of unmanned aerial vehicle and middle wing assembling method

Abstract

The invention relates to a heating curing folding die for glue joint of a middle wing of an unmanned aerial vehicle and a middle wing assembly method. The heating curing folding die for glue joint assembly of the middle wing integrates positioning, pressurizing and heating and comprises a base and a pressing frame which are closed vertically, wherein the base is provided with a positioner assembly, and an inner frame is provided with a heating system; the base and the pressing frame are fixed through positioning pins and bolts. According to the folding mold, accurate positioning of middle wing assembly can be achieved, heating and pressurizing can be conducted in the gluing and curing process at the same time, procedures and sites do not need to be converted, gluing assembly of the unmanned aerial vehicle middle wing can be achieved with low consumption and high quality, the production time is shortened, the product yield and product quality are improved, the investment cost of heating equipment is reduced, and the product production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and relates to a heating and curing closing mold and a method for assembling the middle wings of an unmanned aerial vehicle. Background technique [0002] The connection methods used in the UAV mid-wing assembly include glue joints, riveting joints and screw joints. Among them, the adhesive connection form accounts for a large proportion in the assembly of small and medium-sized UAVs because of its good fatigue resistance, good aerodynamic performance, and no abrasion problems. [0003] The bonding of the mid-wing of the UAV needs to be cured under pressure and heat, and there are strict requirements on the temperature and time. The traditional gluing and closing process is to put the middle wing on the ordinary tooling and push it into the heating room for heating and curing. The heating room is heated by an electric heating plate to increase the temperature in the heating room...

AI Technical Summary

Problems solved by technology

It has high requirements on the size of the site, and a separate heating site needs to be established, which will cause great constraints on scientific research and production of drone products when the production site is insufficient.

[0006] 2. Due to the relatively large space in the traditional heating room, the heating rate is slow

The heating rate in the heating room is relatively slow during the heating process, which increases the time-consuming of bonding and curing virtually, and affects production efficiency

[0007] 3. For small-batch products or small-sized products, when the heating room cannot be placed in full, since the space in the heating room remains unchanged, the energy consumption for heating and heat preservation in the heating room is also constant, which will cause the use of the heating room Inefficient and wasteful energy consumption

[0008] 4. Different adhesives and different products require different curing temperatures and curing times. However, using heating room bonding and curing, placing different products in the heating room at the same time saves energy consumption, but it does not guarantee that each product is safe. Can achieve optimal curing, so that the expected bonding effect cannot be obtained, affecting product quality

[0009] 5. The traditional heating room uses a large number of high-energy-consuming electric heating plates for heating, which consumes a lot of power and has high requirements for electricity safety; in addition, the heating room has a large space and many electric heating plates, so there are many It is not conducive to observe whether the working environment of the heating plate and the heating room is normal during the heating process, and there is a great potential safety hazard

[0010] 6. The tooling is heavy and difficult to move. After completing the bonding process, it needs to be pushed into a fixed heating room, which increases the process conversion and increases labor costs.
