[0002] Power electronic devices, also known as power semiconductor devices, are high-power electronic devices (typically referring to currents ranging from tens to thousands of amperes and voltages of hundreds of volts or more) mainly used in the power conversion and control circuits of power equipment. Power electronic components play an irreplaceable role in modern power systems, industrial automation, new energy, and other fields, and their continuous technological advancements will drive the sustained development of related industries. The processing of power electronic components mainly includes steps such as cutting, scribing, etching, and packaging of semiconductor materials (such as silicon, silicon carbide, gallium nitride, etc.). However, laser cutting technology, due to its high precision, high efficiency, and non-contact processing characteristics, has become an important means in the processing of power electronic components.

[0003] When cutting a workpiece, it is necessary to clamp and fix the workpiece to ensure the cutting effect of the laser cutting device. However, when dealing with some complex-shaped workpieces, the clamp may not be able to fix the workpiece firmly, which may cause the workpiece to loosen or move during the cutting process. The movement of the workpiece may cause the cutting path to deviate or even damage the cutting head.

[0004] Therefore, how to design a laser cutting device that can accurately clamp workpieces with complex shapes is a technical problem that technicians need to solve. Utility Model Content

[0042] Example 1

[0043] In this embodiment, to address the potential problem of workpiece loosening or movement during processing, the technical solution is as follows (see reference). Figures 1 to 6The shape of the positioning rod 106 is adapted to the shape of the positioning groove 104.

[0045] Example 2

[0046] In this embodiment, to solve the problem of inconvenient clamping and fixing of workpieces with complex shapes, the technical solution of this embodiment is as follows, for reference. Figures 1 to 6 The adjusting push rod 210 is an arc-shaped support rod. The adjusting push rod 210 is set on the top of the adjusting push plate 211 and has a mirror symmetrical structure. The outer wall of the adjusting push rod 210 is slidably connected to the outer wall of the side wall clamping plate 219. The inner wall of the threaded sleeve 215 is threadedly connected to the outer wall of the adjusting screw 216. When dealing with workpieces with complex shapes, by rotating the rotating block 214, the threaded connection between the threaded sleeve 215 and the adjusting screw 216 is used to drive the adjusting push plate 211 to slide left and right outside the adjusting screw 216. The adjusting push rod 210 is used to push the rotating plate 209 to rotate around the rotating rod 208, so that the side wall clamping plate 219 contacts the surface of the workpiece, thereby further clamping and fixing the workpiece with complex shapes, which can ensure the stability of the workpiece with complex shapes during processing.

[0047] It should be noted that the shape of the limiting rotating block 213 is adapted to the shape of the limiting rotating groove 212. When rotating the rotating block 214, the rotational connection between the limiting rotating block 213 and the limiting rotating groove 212 can ensure that the rotating block 214 rotates in an directional manner.

[0048] Based on the above embodiments, it can be concluded that when cutting a workpiece, the position of the L-shaped clamping plate 105 on the placement plate 103 is adjusted according to the shape and size of the workpiece, and the L-shaped clamping plate 105 is fixed to the top of the placement plate 103 by the positioning rod 106. Then, the workpiece is placed between the two fixed clamping plates 204. The elasticity of the elastic arc plate 203 can be used to clamp and fix the workpiece. At the same time, by rotating the rotating block 214, the threaded connection between the threaded sleeve 215 and the adjusting screw 216 is used to drive the adjusting push plate 211 to slide left and right outside the adjusting screw 216. The adjusting push rod 210 is used to push the rotating plate 209 to rotate around the rotating rod 208, so that the side wall clamping plate 219 contacts the surface of the workpiece, thereby further clamping and fixing the workpiece with complex shape, which can ensure the stability of the workpiece with complex shape during processing.
