[0002] IGBT (Insulated Gate Bipolar Transistor) is an insulated gate bipolar transistor. It is a composite fully controlled voltage-driven power semiconductor device composed of a bipolar junction transistor (BJT) and an insulated gate field effect transistor (MOSFET). It has the advantages of both the high input impedance of MOSFET (metal-oxide field effect transistor) and the low on-state voltage drop of power transistor (Giant Transistor—GTR). IGBT is the core device for energy conversion and transmission, commonly known as the "CPU" of power electronic devices.

[0003] IGBT modules are key components in power electronic equipment. Their stability and reliability directly affect the performance of the entire system. However, in the production and use of IGBT modules, how to quickly and accurately detect their position and status is an important issue currently faced.

[0009] Furthermore, the height of the baffle is smaller than the height of the integrated module body, and a side of the integrated module body close to the baffle is in contact with the baffle.

[0010] Furthermore, the rotating block is located at the center of the detection platform body, and the threaded rods at both ends of the rotating block have opposite thread directions.

[0011] Furthermore, the top surface of the clamping plate is flush with the top surface of the baffle plate, and a sliding groove matching the shape of the clamping plate is provided on the top surface of the detection platform body.

[0023] Specifically, each outer sleeve rod 5 is threadedly connected to a fixing knob 7 on one side away from the other outer sleeve rod 5, and the fixing knob 7 extends into the interior of the outer sleeve rod 5, so that the fixing knob 7 limits and fixes the inner sleeve rod 6. The height of the baffle 11 is less than the height of the integrated module body 2, and the side of the integrated module body 2 close to the baffle 11 is in contact with the baffle 11, making it more convenient for the detection end 10 to detect the integrated module body 2.
