In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the method that the super thin metal band continues in a kind of radio frequency coaxial-cable production, it comprises the steps:
(a), two metal tape ends to be spliced are cut according to same inclination angle, to form metal strap interfaces;
(b), two metal strap interfaces are formed with one to piece to assembly, and two metal tapes are fixedly installed;
(c), adjust the position of laser weld machine gun head, make rifle head laser point track route with consistent to piece;
(d), start laser-beam welding machine, along piece is welded.
Further, in the step (a), the angle of inclination of each metal tape cutting is 45～60 degree.
Step (d) is preceding carrying out, at the metal tape tag line that draws on to piece.
In the step (b), two metal strap interfaces are drawn close and zero lap.
Described two metal tape sides align.
The present invention also provide a kind of radio frequency coaxial-cable produce in super thin metal band connection device, it comprise be used for metal tape to be spliced end according to the tape-cutting machine structure of same angle of inclination cutting, be used to carry on a shoulder pole establish metal tape and with two metal strap interfaces to the assembly band platform pieced together, be arranged on to piece together the metal tape fixed mechanism on the band platform and be arranged on and piece together band platform one side and rifle head towards the laser-beam welding machine of two metal tapes to piece.
Further, whether consistent it also comprise and be used to show to the rifle head track route of piece and laser-beam welding machine display screen.
Because technique scheme utilization, the present invention compared with prior art has following advantage: adopt connecting method of the present invention, easy to operate, speed is fast, welding effect good, continue the smooth smooth non-notch of metal tape, outer conductor after welding is in follow-up moulding, embossing operation, can not be affected, improve production capacity and qualification rate during radio frequency coaxial-cable is produced, reduced production cost, be applicable to the processing of the ultrathin metal tape of all size.
Description of drawings
Accompanying drawing 1 is connection device structural representation of the present invention;
Wherein: 1, piece together the band platform; 2, fixed mechanism; 3, laser-beam welding machine; 31, pikestaff; 32, rifle head; 4, weld seam; 5, display screen;
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated:
In producing the radio frequency coaxial-cable process, when needs continued to two metal tapes, it adopted laser-beam welding machine to weld, and the specific implementation step is as follows:
At first, two metal tape ends to be spliced are cut according to same inclination angle, to form metal strap interfaces, in the present invention, the angle of inclination is set at 45～60 degree;
Then, two metal strap interfaces are formed with one to piece to assembly, and two metal tapes are fixed, during to assembly, should make that the metal strap interfaces snap to none is overlapping, and metal tape two ends dislocation-free;
Then, adjust the position of laser weld machine gun head, make rifle head laser point track route, after adjusting, on to piece, go out a tag line, make things convenient for laser to weld with thick black stroke with consistent to piece;
At last, start laser-beam welding machine, along piece is welded.
Shown in Figure 1 is the connection device that utilizes said method, it mainly comprises tape-cutting machine structure (not shown), piece together band platform 1, laser-beam welding machine 3 and display screen 5, wherein, the tape-cutting machine structure is mainly used in metal tape inclined cut to be cut, assembly band platform 1 is used for placing metal tape and makes it being stitched together, piece together band platform 1 and be provided with fixed mechanism 2, in the present embodiment, fixed mechanism 2 is for being opened in the chute of piecing together on the band platform 1 symmetrically, be movably arranged on the screw in the chute, as metal tape A, metal tape B is placed on and pieces together on the band platform 1, by regulating the screw of both sides, make metal tape be fixed on and piece together on the band platform 1.Laser-beam welding machine 3 comprises rifle head 32, the pikestaff 31 that is connected with rifle head 32, to the rifle head 32 of piece and laser-beam welding machine 3 point-blank whether display screen 5 be used to observe, particularly, after metal tape A, metal tape B snap to none are fixed on the assembly band platform 1 with misplacing, adjust rifle head position by display screen 5, make its track route consistent to piece with metal tape A, B, on to piece, use a thick black blacking, can carry out laser weld with that, thereby form weld seam 4, this smooth welding joint is smooth, and the both sides non-notch that metal tape continues is as snapping easily.Simultaneously, whole device operation is simpler, does not need manual adjustment in the welding process, and success rate is higher.
