Example Embodiment

[0051] Example 1

[0052] welding system

[0053] refer to figure 1 , shows a welding structure 1 obtained by welding a metal piece and a coaxial cable to each other. The welding structure 1 includes a metal piece 11 providing a welding base, a coaxial cable 12 and a solder 13 filled in the welding seam 14 . figure 1 In the illustrated embodiment, the metal piece 11 provides a flat surface as a soldering surface, and the solder 13 extends from the lower half of the coaxial cable 12 to the surface of the metal piece 11 under the action of gravity in a molten state. , and spread from the right side of the coaxial cable 12 to both sides until the molten solder 13 no longer spreads based on its own material properties and cooling effect, and finally the solder 13 is between the metal piece 11 and the coaxial cable 12. solidified to form solder joints.

[0054] refer to figure 2, which shows a welding system 2 of a metal piece and a coaxial cable, the welding system 2 being us...

[0064] Embodiment 2

[0065] Welding method

[0066] refer to Figure 5 , the present invention also provides a welding method of a metal piece and a coaxial cable, which comprises the following steps:

[0067] S1: Prepare the metal parts and coaxial cables and transfer them to the processing station;

[0068] Specifically, the metal piece and the coaxial cable are moved to the processing station by the moving positioning device 25 . First, through manual operation, the metal piece 11 and the coaxial cable 12 are fixed on the workpiece fixture to maintain a preset positional relationship, so as to facilitate subsequent welding to form the welding structure 1; then, the clamping The workpiece fixture with the metal piece 11 and the coaxial cable 12 is fixed on the workpiece feeding mechanism, and the workpiece fixture is moved to the processing station by manual push or motor drive.

[0069] Those skilled in the art should understand that in the case of mature automated pro...

[0083] Condition of the welding surface of metal parts

[0084] refer to figure 1 , Image 6 and Figure 7 , the welding structure 1 can be roughly divided into three implementations based on the welding surface provided by the metal piece 11 :

[0085] like figure 1 The illustrated implementation has been described in detail in the foregoing first embodiment, and will not be repeated.

[0086] like Image 6 and Figure 7As shown, in order to facilitate the positioning between the metal piece 11 and the coaxial cable 12, the welding surface on the surface of the metal piece 11 is set in the groove 111 that can accommodate the coaxial cable 12, and the groove After the coaxial cable 12 is accommodated in 111 , there is a gap between the bottom of the groove 111 and the coaxial cable 12 .

[0087] When the bottom of the groove 111 is a curved surface, the welding surface has a curved surface, and the slit also has a curved surface. The solder 13 me...

Abstract

The invention discloses a welding system of a metal piece and a coaxial cable. The welding system comprises a heating device which is arranged at a processing station and is in contact with the metal piece or the coaxial cable to carry out heating, a solder feeding device which is arranged adjacent to the heating device and is used for adding brazing filler metal at a connecting part of the metal piece and the coaxial cable and a moving and positioning device which is used for separately clamping and transferring the metal piece and the coaxial cable to the processing station. The invention also discloses a welding method of the metal piece and the coaxial cable. The welding method comprises the following steps: preparing the metal piece and the coaxial cable, and transferring the metal piece and the coaxial cable to the processing station; adding the brazing filler metal at the connecting part of the metal piece and the coaxial cable at the processing station, and carrying out contact heating on the metal piece or the coaxial cable to realize welding; and transferring the welded metal piece from the processing station. According to the welding system and the welding method, the brazing reliability and conduction ratio of the metal piece and the coaxial cable can be well solved, the production efficiency can also be improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of communication device processing, in particular to a welding system and a welding method for metal parts and coaxial cables. Background technique [0002] The structure of base station antenna products in the field of mobile communication is complex, and the internal structure is mainly composed of sheet metal parts, die-casting parts, PCB circuit boards, coaxial cables, etc., which contain various types and specifications of components assembled and structural parts welded. The welding technology between metal structural devices and coaxial cables is particularly important in the production of antennas. The purpose of welding is to ensure a good electrical continuous connection and conduction, and secondly to ensure a durable mechanical connection. Therefore, the consistency of tin content of solder joints between metal structural devices and coaxial cables, the penetration and mechanical strength of solder joints ...
