Wherein, the imitation groove 101 is formed on one surface of the object stage 1, and is used for placing the IGBT copper bar S, thereby positioning the IGBT copper bar S. During processing, the IGBT copper bar S is grabbed by the manipulator and placed into the injection molding machine for injection molding, so that the IGBT shell and the IGBT copper bar S are injection molded into an integrated structure.

The objective table 1 is arranged on the displacement mechanism 2, and the displacement mechanism 2 can drive the objective table 1 to displace. The displacement mechanism 2 is mainly used for transferring work of the IGBT copper bars S so as to carry out material turnover on a production line.

In order to position the IGBT copper bar S, the situation of reverse discharge is avoided, and the device is provided with a positioning pin 3.

As shown in fig. 12, a part of the IGBT copper bar S has a rectangular structure as a whole, but the two ends have different structures, and at this time, the IGBT copper bar S is positioned only by the imitation groove 101, and the situation that the IGBT copper bar S is reversely placed may occur. For this purpose, a positioning groove 102 is provided in the profiling groove 101 of the stage, and a positioning pin 3 is inserted into the positioning groove 102 for positioning the IGBT copper bar S.

The IGBT copper bar S is provided with the through hole 0, when the IGBT copper bar S is placed in the profiling groove 101, the through hole 0 of the IGBT copper bar S is placed corresponding to the positioning pin 3, so that the situation that the IGBT copper bar S is reversely placed can be prevented, the processing efficiency is improved, and the normal operation of the production procedure is guaranteed.

Of course, the hole patterns of the through holes 0 on the IGBT copper bars S are not uniform, and therefore, in order to position the IGBT copper bars S of a plurality of hole patterns, the positioning pins 3 are provided in a detachable structure.

Specifically, the positioning pin 3 is fixed by a bolt 4. The bolt 4 penetrates the surface of the object stage 1 far away from the imitation groove 101 and is connected with the positioning pin 3. So, locating pin 3 can select the type according to the pass of through-hole 0 on IGBT copper bar S to assemble on to objective table 1 through bolt 4, so that locating pin 3 conveniently switches, thereby can fix a position different IGBT copper bars S, in order to improve this commonality of transferring the platform.
