Problems solved by technology

However, the main disadvantage of this technology is that the punching head can only bend one electrode at a time, and each punching head can only bend electrodes of the corresponding size. After the bending of a group of electrodes is completed, the punching head needs to be replaced. Bending another group of electrodes, all the electrodes of such an IGBT module need to be bent multiple times, the bending efficiency is low, and it is not conducive to large-scale mass production; in addition, the friction between the bending punch and the electrode during bending is relatively Large, easy to scratch the surface of the electrode, which will have a bad effect on the appearance and subsequent use of the module

Embodiment Construction

[0029] The invention discloses a device capable of bending all electrodes on an IGBT module at one time by means of rolling.

[0030] Such as figure 1 or Figure 4 As shown, in the embodiment of the present invention, a driving device is used to drive the carrying plate to move relative to the rolling part in the horizontal direction. In the embodiment of the present invention, an electric roller 1 and a rolling part 3 are added on the basis of the original carrying plate 2 . The carrier plate 2 is used for fixing the IGBT module 4 . The electric roller 1 is driven by a driving device, and is used to drive the carrying plate 2 to move in the horizontal direction. The rolling part 3 further includes a connecting shaft 31 and several rollers 32 or 33 . Both ends of the connecting shaft 31 are connected to fixed parts on the device, and the height of the connecting shaft 31 can be adjusted according to the height of the IGBT module 4 . The first roller 32 and the second roll...

Abstract

The invention discloses a roller electrode bending device which comprises a bearing plate used for fixing an IGBT module. The roller electrode bending device is characterized by further comprising a rolling component located above the IGBT module and a drive device for driving any one of the bearing plate and the rolling component and enabling the bearing plate and the rolling component to move relative to each other in the horizontal direction. By means of rolling of the rolling components, all electrodes on the IGBT module can be bent in a one-shot mode, meanwhile, scratches and abrasion are reduced, and the bending efficiency of the electrodes is improved.

Description

technical field [0001] The invention belongs to the field of electronic manufacturing, in particular to a device for bending electrodes of an IGBT module. Background technique [0002] IGBT (Insulated Gate Bipolar Transistor), Insulated Gate Bipolar Transistor, is a composite full-control voltage-driven power semiconductor device composed of BJT (Bipolar Transistor) and MOS (Insulated Gate Field Effect Transistor). IGBT has the advantages of small driving power and low saturation voltage, and is very suitable for use in converter systems with a DC voltage of 600V and above, such as AC motors, frequency converters, switching power supplies, lighting circuits, traction drives and other fields. [0003] After the IGBT module is perfused with gel and the top cover is installed, the electrodes must be bent to facilitate subsequent module installation. The electrode bending requires that the height of each group of electrodes is consistent after bending, and the electrode surface...
