[0003] The MOSFET power module includes a base, a package shell, a MOSFET device and a MOSFET driver. The MOSFET device and the MOSFET driver are arranged on the base, and a connection contact is arranged on the base, and is connected to the MOSFET driver through a connection electrode. The base, the MOSFET device and the MOSFET driver are arranged in the package shell, and the connection contact passes through the base and is exposed from the package shell to connect with an external device. The connection electrode is made of a conductive material and can be bent and shaped. The existing MOSFET assembly is to first install the MOSFET device and the MOSFET driver on the base through an assembly mechanism, and then manually bend the connection electrode, weld one end to the connection contact, and connect the other end to the MOSFET driver contact. In order to realize automated processing, it is necessary to use a bending device to bend the connection electrode in advance, and then go to the next process to reposition the workpiece, and then weld it by a welding mechanism.

After the pushing chuck 27 of the pushing assembly 22 pushes the formed connecting electrode to the connecting contact area of ​​the base, the material mixing drive motor 331 rotates forward to drive the driving wheel 332 to rotate. Under the action of the linkage chain and the linkage shaft 36, the material mixing heating assembly 351 and the material mixing gluing assembly 352 are moved forward. First, the material mixing heating assembly 351 is located in the connecting contact area of ​​the base to preheat it, and then it continues to move forward so that the material mixing gluing assembly 352 is located in the connecting contact area of ​​the base, and conductive glue is applied to it to connect the end of the connecting electrode with the connecting contact of the base. Then, the material mixing drive motor 331 is reversed to move the material mixing heating assembly 351 and the material mixing gluing assembly 352 backward, so that the material mixing heating assembly 351 is located above the connecting contact area of ​​the base again for curing.
