Problems solved by technology
[0003] The purpose of the present invention is to solve the problem that the tail end of the radial rib antenna and the mast are connected by metal parts or by one-time molding carbon fiber material. During the process of curling, folding and unfolding of the rib, it is easy to produce multiple angles due to uneven force Irregular creases or even tears will affect the quality of antenna signal transmission and reception, and the mold of one-time molding carbon fiber material is large and the cost is high. A method for connecting the rib end of the radial rib antenna to the mast is provided. Its technical scheme is as follows:

Embodiment Construction
[0015] refer to Figure 1 to Figure 5 , a method of connecting the tail end of the rib plate and the mast of the radial rib antenna, which uses aramid fabric 2 to bond the mast 3 and the tail end 4 of the rib plate finger-fork, and use the method of precise positioning of the mold 1 to make the rib The tail end 4 of the board is precisely connected to the mast 3 .
[0016] The first step is to stick the aramid fabric 2 around the mast 3 for a week and then stick it together;
[0017] The second step, after the glue dries, trim the aramid fabric 2 to the same shape as the end 4 of the rib, and cut it perpendicular to the mast 3 into several equal-width cloth strips 2-1, at the end of the rib 4. A number of incisions 4-1 are arranged corresponding to each cloth strip 2-1. The width of the incision 4-1 is one-half the width of the corresponding position of the cloth strip 2-1. The incisions on both sides of the rib end 4 4-1 is aligned with the inner side of the corresponding c...

The invention discloses a connection method for a rib plate tail end and a mast of a radial rib antenna and a die, and belongs to the technjical field of a radial rib antenna. The problem that a multi-angle irregular fold line or even the tearing phenomenon easily occurs in the processes of curling, folding and unfolding of a rib plate caused by uneven stress due to the fact that the rib plate tail end and the mast of the existing radial rib antenna are connected by a metal piece or are made of a one-step forming carbon fiber material, thus the transmit-receive quality of the antenna signal is influenced, as well as the problems that the one-step forming carbon fiber material requires a large die and is high in cost are solved. The connection method adopts aramid cloth to bond the mast and the rib plate tail end in an interdigital way and a precise positioning method for the die is adopted, the mast and the rib plate are precisely connected. The connection method for the rib plate tail end and the mast of the radial rib antenna and the die are used for connecting the rib plate tail end with the mast of the radial rib antenna.
Description
Technical field: [0001] The invention belongs to the technical field of radial rib antennas, and in particular relates to a method for connecting the tail end of a rib plate and a mast of a radial rib antenna. Background technique: [0002] The radial rib antenna has the advantages of light weight, large diameter, low transportation cost and high accuracy. However, at present, the connection between the rib end of the radial rib antenna and the mast is made of metal parts or a one-time forming carbon fiber material, which is curled on the rib. During the process of folding and unfolding, it is easy to produce multi-angle irregular folds or even tearing due to uneven force, which affects the transmission and reception quality of antenna signals. Moreover, the mold for forming carbon fiber materials at one time is large and the cost is high. Invention content: [0003] The purpose of the present invention is to solve the problem that the connection between the tail end of th...
