Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Present embodiments provide a kind of slotted electrode of thin film capacitor lead welding machine, as shown in Figures 2 and 3, slotted electrode comprises capacitor body main body 3, gilding layer 4, gilding layer 5, electrode 1, electrode 2, lead-out wire 6 and lead-out wire 7, electrode 1 has the rectangular slot 9 that can contain lead-out wire cross section semicircle, electrode 2 has the rectangular slot 8 that can contain lead-out wire cross section semicircle, the semicircle in lead-out wire 6 cross section is solded in gilding layer 4, second half of lead-out wire 6 cross section semicircle is stayed in the rectangular slot 9 of outer electrode, and, the semicircle in lead-out wire 7 cross section is solded in gilding layer 5, second half of lead-out wire 7 cross section semicircle is stayed in the rectangular slot 8 of outer electrode, after having welded, slotted electrode after withdrawing as shown in Figure 3.
Fig. 2 is the transverse sectional view group of the utility model embodiment.In the drawings the capacitor body 3 that metal spraying completes is poured in the vibrating disk of bonding machine, make capacitor body enter straight shape vibra shoot by vibration and by the charging ram of bonding machine, capacitor body is shifted onto between two pairs of electrodes again, be the position shown in Fig. 2.
Or the degree of depth of rectangular slot is the semicircle radius length in lead-out wire cross section.Namely the groove depth of slotted electrode is consistent with the technical papers of the design lead-out wire of welded electric capacity and gilding layer thickness, namely when lead-out wire 6 and lead-out wire 7 are 0.8mm, when the thickness of gilding layer 4 gilding layer 5 is 0.4mm, groove depth should be selected to be the slotted electrode of 0.4mm, now the depth of weld is 0.4mm, as shown in Figure 3.Lead-out wire 6 and lead-out wire 7 have half to be exposed at the outside of gilding layer, and second half has been solded in gilding layer 4 gilding layer 5.Now sample testing two results: one is be contained on tensile tester by capacitor body, records weld part potential energy and bears 4Kg with upper pulling force, then without rosin joint; Two is the loss tangents with electric bridge test capacitors fuse, if in the scope that file specifies, then damage minimum to deielectric-coating when proving welding, damage is also in prescribed limit.
The utility model improves the straight copper electrode of bonding machine, the flat face contacted is processed one and can contain lead-out wire semicircle, and another semicircle is exposed at outside the rectangular slot of electrode, as shown in Figure 2 with lead-out wire.This electrode is claimed to be slotted electrode.When lead-out wire diameter is 0.6mm, the groove depth of slotted electrode is 0.3mm, and when lead-out wire diameter is 0.8mm, the groove depth of slotted electrode is 0.4mm, by that analogy.
Slotted electrode of the present utility model, thoroughly solves the technological problems of thin film capacitor lead-out wire depth of weld uniformity and adjustability, specifically solves following two problems:
the uniformity of capacitor two lead-out wire depths of weld, because this technology does not lean on the pressure of electrode and distance also not by flattening lead-out wire but leaning on the Baltimore groove of electrode to contain the half of lead-out wire, second half is solded into gilding layer, turn large plane by Baltimore groove both sides again and withstand metal spraying face, unfused both sides, play the effect of mechanical position limitation, realize even depth welding again and again.
the adjustability of capacitor two lead-out wire depths of weld.Because the groove depth of slotted electrode can be processed as required, when the diameter of lead-out wire is 0.8mm, the degree of depth of groove can be processed into 0.4mm, and now the depth of weld is 0.4mm.When the diameter of lead-out wire is 1mm, the degree of depth of groove can be processed into 0.5mm or 0.4mm, is that 0.5mm is good actually, should 0.4mm, depends on the thickness of gilding layer.
So, 1. due to the uniformity of the depth of weld, make the solder yield of capacitor to reach 100%, namely when welding current mixes up constant by technique, the uniformity of welding can reach 100%; So there will not be that side weld of prior art dark, the chance phenomenon of another side rosin joint.
2. due to the adjustability of the depth of weld, so the kind of welding electrode groove depth can be determined according to the thickness of gilding layer design, write technical papers, thus realize depth of weld datumization management and control, instead of produce by workman's experience of prior art.
3. due to uniformity and the adjustability of the depth of weld, thus realize the depth of weld ideal consistent with gilding layer thickness matching and weld.Lead-out wire can not exceed gilding layer more at random, the deielectric-coating below damage gilding layer.Thoroughly avoid prior art and be solded into deielectric-coating at random, burn deielectric-coating, the hidden danger of quality that condenser loss angle tangent value is exceeded standard, makes capacitor electrode properties percent of pass increase substantially.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
