[0002] With the rapid development of wireless communication technology, high-precision positioning antennas have been widely used in unmanned driving, marine navigation, surveying and mapping, and military fields. However, during the antenna assembly process, the accuracy of welding positioning directly affects the performance and service life of the antenna. Antenna welding of communication equipment is a job involving precision technology and techniques. When assembling the antenna, the metal pins of the antenna are soldered to the circuit board of the communication equipment by soldering, so that the antenna and the circuit board of the communication equipment are electrically connected.

[0003] In the assembly and welding of traditional antennas, the welding of antenna pins needs to be ensured with high precision. During the welding process, the assemblers hold the soldering iron and solder wire, which is not convenient for supporting and fixing the antenna. As a result, the antenna is easily displaced or moved during the welding process, increasing the probability of cold soldering. In addition, the angle between the antenna and the circuit board cannot be controlled, resulting in deviations in the angle or direction of the antenna after installation, which is not conducive to the later assembly and debugging of the electronic equipment.
