[0002] The IGBT module is a modular semiconductor product that is packaged by connecting the IGBT and FWD through a specific circuit bridge. During the production process of the IGBT module, auxiliary tooling is usually required to fix the IGBT module being processed and produced.

[0003] In the prior art, when using auxiliary tooling to fix the IGBT module, it is usually necessary to place the IGBT module inside the lower layer of the tooling, and then connect and fix the upper and lower layers of the tooling, and use bolts to fit the upper and lower layers of the tooling tightly to press the IGBT module. However, in actual use, four bolts need to be installed on the four corners to connect the upper and lower layers of the tooling, and when disassembling the tooling, all four bolts need to be removed. Since the bolts need to be turned many times, the process of connecting and fixing the upper and lower layers of the tooling is not convenient. Therefore, it is necessary to improve an auxiliary tooling for IGBT module production to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0025] See also Figure 1-4 The utility model provides a technical solution: an IGBT module production auxiliary tooling, including a tooling lower block 1, a placement groove 4 is opened inside the tooling lower block 1, a positioning clamping mechanism 2 is arranged on the top of the tooling lower block 1, and a lower layer replacement mechanism 3 is arranged on the bottom of the tooling lower block 1.

[0026] The positioning clamping mechanism 2 comprises a positioning component 21 and a clamping component 22 . The clamping component 22 is arranged on the top of the positioning component 21 .

[0027] Furthermore, the positioning component 21 includes a positioning pin 211, which is fixedly installed on the top of the tooling lower block 1, and a clamping column 212 is fixedly installed on the top of the positioning pin 211. The outer part of the positioning pin 211 is slidably installed with a tooling upper laminate 213, and the interior of the tooling upper laminate 213 is provided with a machined groove 214, which is convenient for auxiliary positioning of the connection between the tooling lower block 1 and the tooling upper laminate 213 through the positioning component 21.

[0028] Furthermore, holes are provided at corresponding positions of the upper laminate 213 of the tooling and the positioning pins 211, and the positioning pins 211 are slidably installed inside the holes provided inside the upper laminate 213 of the tooling, so as to facilitate positioning under normal conditions.

[0029] Furthermore, the snap-in assembly 22 includes a sliding connection column 221, which is fixedly installed on the top of the upper laminate 213 of the tooling. A sliding column 222 is slidably installed inside the sliding connection column 221, a snap block 223 is fixedly installed on the outer side of the sliding column 222, a spring 224 is arranged on the outside of the sliding column 222, and a sliding wheel 225 is fixedly installed on the bottom of the snap-in assembly 22, so as to facilitate the snap-in installation of the lower block 1 of the tooling and the upper laminate 213 of the tooling through the snap-in assembly 22.

[0030] Furthermore, the clamping block 223 is clamped with the clamping column 212, and the outer portion of the sliding wheel 225 is movably installed with the top of the laminate 213 on the tooling, thereby improving stability. Example

[0031] See also Figure 5 In combination with the first embodiment, it is further obtained that the lower layer replacement mechanism 3 includes an internal thread column 31, the internal thread column 31 is fixedly installed at the bottom of the tooling lower layer block 1, the internal thread of the internal thread column 31 is installed with a bolt 32, the outside of the bolt 32 is provided with a bottom plate 33, and the bottom of the bottom plate 33 is fixedly installed with a supporting leg 34, so as to facilitate the replacement of the tooling lower layer block 1 through the lower layer replacement mechanism 3.

[0032] Furthermore, holes are provided at corresponding positions of the bottom plate 33 and the bolts 32 , and the bolts 32 are slidably installed inside the holes provided inside the bottom plate 33 , so as to facilitate installation and disassembly of the lower block 1 of the tooling.

[0033] In actual operation, when the device is used, after the IGBT module to be processed is placed inside the placement slot 4, the upper laminate 213 of the tooling is aligned with the lower block 1 of the tooling to move it downward. At this time, the positioning pin 211 enters the interior of the upper laminate 213 of the tooling. When the clamping column 212 contacts the clamping block 223, the clamping block 223 moves inward under the action of the inclined surface of the clamping block 223, so that the sliding column 222 slides inside the sliding connection column 221. When the clamping block 223 can be clamped with the clamping column 212, the spring 22 4, the clamping block 223 moves outward to fix the clamping column 212. At this time, the upper laminate 213 of the tooling is fixed, and the IGBT module is tightly fixed. Then the IGBT module can be produced and processed. After the production and processing is completed, the sliding column 222 is pulled to disengage the clamping block 223 from the clamping column 212, so that the lower block 1 of the tooling is separated from the upper laminate 213 of the tooling. At this time, the IGBT module can be taken out. When the lower block 1 of the tooling needs to be replaced, the bolt 32 is removed to make the bolt 32 leave the internal threaded column 31, and then it can be replaced.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
