Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of IGBT coating, in particular to an IGBT thermal grease coating tool. Background Art
[0002] IGBT (Insulated Gate Bipolar Transistor) combines the advantages of power transistor (Giant Transistor—GTR) and power field effect transistor (Power MOSFET), has good characteristics, and is widely used. IGBT is also a three-terminal device: gate, collector and emitter.
[0003] When an existing IGBT module is in use, it is necessary to coat the surface of the module with thermal grease for subsequent use. However, in the prior art, when coating the IGBT module, a brush roller is directly rolled on the surface. Directly brushing on the surface cannot make the thermal grease evenly coated on the surface, affecting its subsequent thermal conductivity. Based on the deficiencies of the existing technology, the utility model designs an IGBT thermal grease coating tool. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides an IGBT thermal grease coating tool, which has the advantage of uniformly coating the thermal grease.
[0005] The utility model provides the following technical solution: an IGBT thermal grease brushing tool, comprising a base plate, a side block is installed on the top of the base plate, rotating grooves are arranged on both sides of the outer surface of the side block, and brushing structures are arranged inside the two rotating grooves; the two brushing structures comprise stainless steel plates, the two stainless steel plates are rotatably connected to the rotating grooves, a fixed frame is installed on one side of the two stainless steel plates, a dust cover is hingedly installed on the top of the two fixed frames, and a mesh surface is arranged inside the fixed frame.
[0006] As a preferred technical solution of the utility model, a handle is installed on one side of the outer surface of the fixing frame.
[0007] As a preferred technical solution of the utility model, card slots are provided on both sides of the bottom of the fixing frame.
[0008] As a preferred technical solution of the utility model, card frames are installed on both sides of the top of the bottom plate, and the module bodies are placed inside the two card frames.
[0009] As a preferred technical solution of the utility model, hinge seats are provided on both sides of the two card frames, and the two hinge seats are fixedly connected to the bottom plate.
[0010] As a preferred technical solution of the present utility model, support rods are hingedly installed inside the two hinged seats.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The IGBT thermal grease coating tool has a coating structure and is fixed by placing the module body into a card frame. At this time, by pulling the handle, the stainless steel plate drives the fixing frame to be clamped on the top of the module body. At this time, since the stainless steel plate is softer, the fixing frame can fit more closely with the top of the module body. At this time, the dust cover can be opened and the mesh surface can be brushed back and forth by a brush roller. At this time, the thermal grease can be evenly attached to the surface of the IGBT module after passing through the mesh surface, thereby achieving the purpose of evenly coating the thermal grease.

[0020] See also Figure 3-4 A handle 44 is installed on one side of the outer surface of the fixing frame 42. Slots 46 are provided on both sides of the bottom of the fixing frame 42.
[0021] The handle 44 is provided to facilitate pulling up the fixing frame 42 so as to take out the module. The slot 46 is provided to allow the support rod 7 to support it.
[0022] See also Figure 1-2 , card frames 5 are installed on both sides of the top of the bottom plate 1, and module bodies 8 are placed inside the two card frames 5. Articulated seats 6 are arranged on both sides of the two card frames 5, and the two articulated seats 6 are fixedly connected to the bottom plate 1. Support rods 7 are hingedly installed inside the two articulated seats 6.

[0024] Working principle, when an IGBT thermal grease coating tool is used, in the initial state, first pull up the fixed frame 42 through the handle 44, and put the module body 8 into the card frame 5 for fixing. At this time, by pulling the handle 44, the stainless steel plate 41 drives the fixed frame 42 to be stuck on the top of the module body 8. At this time, since the stainless steel plate 41 is made of a softer material, the fixed frame 42 can fit more closely to the top of the module body 8. At this time, the dust cover 43 can be opened, and the mesh surface 45 can be brushed back and forth with a brush roller. At this time, the thermal grease can be evenly attached to the surface of the IGBT module after passing through the mesh surface 45.
