Embodiment
Principle of the present invention is in the center soldering operation with the conventional high-tension capacitor, elements on either side aluminium foil end face ward off end tin and element one this twice step of side end face fuse soldering is finished in the discrete component manufacturing procedure in advance, to reach the reasonable distribution working strength, the purpose of enhancing productivity.
Below in conjunction with accompanying drawing, specify the present invention.
See also Fig. 2, it is a kind of embodiment flow chart of the process for producing core of high-voltage capacitor of the present invention, and it comprises that discrete component manufacturing procedure (step S200), center press-fit operation (step 210) and center soldering operation (step 220) three process.
Wherein, discrete component manufacturing procedure (step S200) may further comprise the steps again:
S201, element roll around.Discrete component by polypropylene film and aluminum foil coil around forming.
S202, component pressure.The element that coiling is finished will carry out voltage-withstand test, and whether detecting element is breakdown and whether quality is qualified.
S203 wards off end tin at the discrete component two ends.
S204, at the outside encapsulation piece that attaches of discrete component, described encapsulation piece plays the effect of insulation.
S205 sticks on fuse on the discrete component side.
S206, with the fuse soldering at the discrete component end face.
After discrete component machines, just enter center and press-fit operation (step 210), it is with the processing of exerting pressure after the stacked on request placement of a plurality of elements, to form the global shape of center.It should be noted that when press-fiting, need have the end face of fuse to be placed on a side soldering on the element, and the 3rd side of center has been made of in all solderings jointly the end face of fuse.
At last, enter center soldering operation (step 220) again, it may further comprise the steps:
S221 places brace on request in center first side, and the fuse of discharge resistance, each element side of center is linked to each other with the brace soldering.It should be noted that, first side described in this step be meant on the center with soldering have fuse the 3rd side adjacent face, since discrete component add man-hour each element one end all soldering fuse is arranged, so this step only need link to each other with discharge resistance every fuse with the brace soldering.
S222, the face tin soldering brace on request in center second side, and discharge resistance linked to each other with the brace soldering of correspondence on request.Second side described in this step be meant on the center with soldering have fuse the 3rd side right face (promptly in the discrete component manufacturing procedure, having warded off the face of end tin).Because discrete component adds and warded off the end tin man-hour on this side, therefore only need use face tin just brace can be linked to each other with the center soldering here.Brace in this step is to be used for different centers are connected in series, so this brace will link to each other with the discharge resistance soldering.
Especially, present embodiment has adopted the soldering processes that end tin and face tin combine.Wherein, ward off the end and can adopt tin zinc solder plate during tin, described tin zinc solder plate liquid-solid two-phase coexistence temperature is 260～380 ℃, and liquidus temperature is 380 ℃, welding job temperature 〉=380+50 ℃.Can adopt tin lead welding tin bar when warding off face tin, described tin lead welding tin bar liquid-solid two-phase coexistence temperature is: 183～215 ℃, liquidus temperature is: 215 ℃, and temperature 〉=215+50 ℃ of its welding job.
Present embodiment adds at discrete component just wards off upper base tin at the element two ends man-hour, and be all fuses in the soldering of each element, therefore can reduce the working strength of operating personnel when follow-up center soldering operation greatly, can improve the quality of soldering effectively, and improve operating personnel's operating efficiency, more reasonably distributed the operating time in the whole center production process.In addition, because traditional discrete component manufacturing procedure is to be finished by automation equipment, and that the operation of end tin and this twice step of element end face fuse soldering is warded off at the discrete component two ends is simple relatively, therefore this twice step can be incorporated in the automation equipment and finish, thereby replace traditional manual operation, can improve the production efficiency of center greatly.
Above-mentioned is a kind of preferred implementation of the present invention only, but does not limit the present invention with this.Any increase on the basis of the technology of the present invention feature, deletion and removable parts operation, but still possess the process for producing core of beneficial effect of the present invention, all should be in protection scope of the present invention.
For ease of understanding the present invention, below a center that goes out by explained hereafter of the present invention is specifically introduced.See also Fig. 3 and Fig. 4, it is respectively second side and the first side embodiment schematic diagram that utilizes a kind of center that the present invention produces.As seen from Figure 3, three groups of centers are gripped by clamping plate 32, and every group of center all is laminated with a plurality of elements 31.Brace 33 and brace 34 solderings are in center second side, each element 31 all and a fuse (not shown) is arranged, and every fuse all is connected on brace 33 and the brace 34 on request, thereby realizes the connection in series-parallel relation between the element 31.
Fig. 4 is center first side schematic view, and brace 41 and brace 42 all are placed on center second side, and all is connected with discharge resistance 43 on request on every group of center, and brace 41 and brace 42 are to be used to realize not the connection in series-parallel between center on the same group.
The present invention is by advanceing to the twice step in traditional center soldering operation (being that end tin and the soldering of element end face fuse are warded off in the discrete component two ends) in the discrete component manufacturing procedure and finish, can reduce the working strength of operating personnel when center soldering operation effectively, thereby also improve the brazing quality of center.And, obtain according to inventor experiment, adopt technology of the present invention after, the average manufacturing time of each center shortened to about 13 minutes by original about 20 minutes, had significantly improved production efficiency, can bring huge economic interests for enterprise.
More than disclosed only be several specific embodiment of the present invention, but the present invention is not limited thereto, any those skilled in the art can think variation, all should drop in protection scope of the present invention.
