Automatic system and implementation method for welding metal part and coaxial cable

Abstract

The invention discloses an automatic system for welding a metal part and a coaxial cable. The automatic system comprises a tin feeding device, a heating device, a movement positioning device and an electric control device, wherein the tin feeding device is arranged at a first station and is used for adding tin paste to the connecting position of the metal part and the coaxial cable, the heating device is arranged at a second station and is used for performing induction heating on the connecting position to which the tin paste is added, the movement positioning device is used for respectively clamping the metal part and the coaxial cable and moving to the first station and the second station in sequence, and the electric control device is used for controlling all of the devices of the automatic system. The invention further discloses an implementation method for welding the metal part and the coaxial cable. According to the automatic system and the implementation method, the non-contact induction heating is realized, an endothermic effect of a metal structural member is basically solved, additionally, the welding spot heating uniformity is guaranteed, and the welding reliability of products is increased.

Description

technical field [0001] The invention relates to the field of mobile communication antenna manufacturing and processing, in particular to an automatic system and an implementation method for welding metal parts and coaxial cables. Background technique [0002] Antenna is a key component of mobile communication network coverage. Antenna products have a complex structure. The internal structure is mainly composed of sheet metal parts, die-casting parts, PCB circuit boards, coaxial cables and other types and varieties of components assembled and structural parts welded. Because of the fixed wire characteristics of the antenna product, the purpose of its welding must ensure two aspects, one is to ensure a good electrical continuous connection and conduction, and the other is to ensure a durable mechanical connection. Therefore, the consistency of tin content of solder joints, the penetration of solder joints, and the mechanical strength restrict the electrical parameters and inte...

Problems solved by technology

In order to make its heating meet the welding requirements, high temperature transmission or long-term contact welding is required, resulting in a decrease in the quality and reliability of the solder joints. At the same time, the soldering iron tip is easily oxidized at high temperature for a long time, and the service life is reduced; if the volume of the metal structure is relatively large When it is large, the temperature of the soldering iron tip will be lowered during the soldering process, which cannot guarantee the consistency of the soldering temperature. At the same time, the manual soldering method cannot guarantee the consistency of the soldering time and the amount of tin sent. The operation method is inefficient and the quality is consistent. poor sex
