Description

The pressure electrode assembly of power model

Technical field

This utility model is related to Power semiconductor products field and in particular to a kind of pressure electrode assembly of power model.

Background technology

Power model is that by certain function combinations, embedding becomes a module to power power electronic device again.Work(with baffle plate In the finished product production process of rate module (as shown in Figure 4), need to flatten electrode, existing method is to flatten one by one manually, effect Rate is low, and because discontinuity, irregular waveform easily in electrode, affects yield rate.

Utility model content

This utility model is directed to problem above, there is provided a kind of structure is simple, compacting efficiency high, the power mould of high yield rate The pressure electrode assembly of block.

The technical solution of the utility model is: is provided with baffle plate between the two neighboring electrode of described power model, described pressure Electrode assembly includes driving cylinder and the briquetting being connected with driving cylinder, and described briquetting bottom is provided with recessed with what described baffle plate was adapted to Groove.

It is provided with the pre- pressure head equal with number of poles, described briquetting is provided with accommodating pre- on described briquetting, outside groove The through hole of pressure head, the head being opened on pre- pressure head of described through hole is adapted to completely and extends to the side of briquetting；

Described pre- pressure head is connected with driving means by connecting rod, and described connecting rod is connected to the outside of pre- pressure head.

Described pre- pressure head be cube block or corner block or with electrode contact surface for arc wedge.

The beneficial effects of the utility model are: are once suppressed with briquetting, not only suppress smooth, high yield rate, and suppress speed Degree is fast；The groove being adapted to baffle plate is provided with briquetting, baffle plate in pressing process, will not be damaged；Outside groove and electrode position The place putting adaptation arranges pre- pressure head, before briquetting compacting, first carries out precompressed with pre- pressure head, it is to avoid artificial precompressed, in hgher efficiency.

In figure 1 is power model, and 11 is baffle plate, and 2 is briquetting, and 21 is groove, and 22 is pre- pressure head.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is illustrated.

As shown in figure 4, the pressure electrode assembly of power model, between the two neighboring electrode of described power model 1, it is provided with gear Plate 11, as shown in Figure 1-2, the briquetting 2 that described pressure electrode assembly is included driving cylinder and is connected with driving cylinder, described briquetting 2 Bottom is provided with the groove 21 being adapted to described baffle plate.

The method of work of the first embodiment of the present utility model: power model 1 is placed on below briquetting 2, by hand will After each electrode pre-bending, start driving cylinder, make briquetting 2 close to power model 1, baffle plate 11 fits in groove 21, directly To electrode is flattened (as shown in Figure 5), then briquetting 2 resets, and continues the compacting of next power model 1.

Second embodiment of the present utility model, as Figure 2-3, in the first embodiment on briquetting 2, groove It is provided with the pre- pressure head 22 equal with number of poles, described briquetting 2 is provided with the through hole of accommodating pre- pressure head 22, described through hole outside 21 The head being opened on pre- pressure head 22 be adapted to completely and extend to the side of briquetting 2；

Described pre- pressure head 22 is connected with driving means by connecting rod, and described connecting rod is connected to the outside of pre- pressure head 22.

Described pre- pressure head 22 be cube block or corner block or with electrode contact surface for arc wedge.

The work process of the program is: power model 1 is placed on below briquetting 2, first starts the driving means of pre- pressure head 22, So that pre- pressure head 22 is moved downward, to pre- pressure head 22 completely disengage from briquetting 2 when, driving means drive pre- pressure head 22 inward (i.e. Electrode direction), electrode is bent in advance, then pre- pressure head 22 resets, the driving cylinder of briquetting 2 drives briquetting to move downward, baffle plate 11 fit in groove 21, until electrode is flattened, then briquetting 2 resets.This programme is with respect to the first artificial precompressed one by one Scheme, in hgher efficiency.

This utility model briquetting is once suppressed, and not only suppresses smooth, high yield rate, and pressing speed is fast；Set on briquetting 2 Put the groove 21 being adapted to baffle plate 11, baffle plate 11 in pressing process, will not have been damaged；It is adapted to electrode position in groove 21 outside Place pre- pressure head 22 is set, before briquetting 2 compacting, first carry out precompressed with pre- pressure head 22, it is to avoid artificial precompressed, in hgher efficiency.
