[0018] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0019] Example 1: Please refer to Figure 1 - Figure 3, a fixing device for IGBT production in this embodiment includes a conveyor belt 1 and a vertical plate 2, a base 4 is fixedly connected to the top of one side of the vertical plate 2, a hydraulic cylinder 5 is fixedly connected to the bottom of the base 4, a connecting plate 6 is fixedly connected to the bottom of the hydraulic cylinder 5, an operating plate 7 is fixedly connected to the bottom of the connecting plate 6, the operating plate 7 is movably connected to one side of the vertical plate 2, a motor 8 is arranged at one end of one side of the operating plate 7, a bidirectional threaded rod 9 is fixedly connected to one end of the motor 8, two connecting blocks 10 are threadedly connected at both ends of the bidirectional threaded rod 9, two clamping blocks 11 are fixedly connected to the bottom of the two connecting blocks 10, the two clamping blocks 11 are movably connected between the two brackets 3, and an IGBT body 18 is arranged between the two clamping blocks 11;

[0020] The plurality of IGBT bodies 18 are placed on the surface of the conveyor belt 1, and the conveyor belt 1 is started, so that the IGBT bodies 18 are moved to the bottom of the vertical plate 2 in sequence. When the IGBT bodies 18 are located below the vertical plate 2, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 drives the connecting plate 6 to move downward, and the connecting plate 6 drives the operating plate 7 to move downward, and the operating plate 7 drives the connecting block 10 and the clamping block 11 to move downward, so that the two clamping blocks 11 are located on both sides of the IGBT body 18.

[0021] Secondly, start the motor 8, the motor 8 will drive the bidirectional threaded rod 9 to rotate. Since the threads at both ends of the bidirectional threaded rod 9 are opposite, the bidirectional threaded rod 9 will drive the two connecting blocks 10 to approach each other, and the connecting blocks 10 will drive the clamping blocks 11 to approach each other, thereby clamping the IGBT body 18. Then start the hydraulic cylinder 5, the hydraulic cylinder 5 will drive the connecting plate 6 and the operating plate 7 to move upward, the operating plate 7 will drive the connecting block 10 and the clamping block 11 to move upward, and the clamping block 11 will drive the IGBT body 18 to move upward, so as to facilitate the IGBT body 18 to be clamped and fixed for testing;

[0022] Further, the bottom of the vertical plate 2 is fixedly connected to two brackets 3, the conveyor belt 1 is located between the two brackets 3, the vertical plate 2 is located on the top of the conveyor belt 1, and the operating panel 7 moves downward along one side of the vertical plate 2. The downward movement of the operating panel 7 will drive the clamping block 11 to reach the top of the conveyor belt 1, so as to facilitate the clamping and fixing of the IGBT body 18;

[0023] Further, a clamping block 12 is fixedly connected to one side of the connecting block 10, a clamping groove 13 is processed inside the operating panel 7, and the clamping block 12 is movably connected inside the clamping groove 13.

[0025] Further, one end of the operating plate 7 is fixedly connected with a slide groove 16, and the slide groove 16 is movably connected to the outside of the bracket 3. When the hydraulic cylinder 5 drives the connecting plate 6 and the operating plate 7 to move downward, the operating plate 7 will drive the slide groove 16 to move downward, and the slide groove 16 will clamp the outside of the bracket 3 and move downward. By providing the slide groove 16, the operating plate 7 can move downward along one side of the vertical plate 2, and the operating plate 7 is prevented from being separated from one side of the vertical plate 2.

[0026] Furthermore, the top of the bracket 3 is fixedly connected with two limit blocks 17, and the limit blocks 17 are located on the top of the operating panel 7. By setting the limit blocks 17, the limit blocks 17 will limit the operating panel 7 to prevent the operating panel 7 from moving upward and leaving the top of the bracket 3.

[0027] Working principle: By starting the hydraulic cylinder 5, the hydraulic cylinder 5 will drive the connecting plate 6 and the operating plate 7 to move downward, and the operating plate 7 will drive the connecting block 10 and the clamping block 11 to move downward, so that the two clamping blocks 11 are located at the top of the conveyor belt 1, and at the same time, the two clamping blocks 11 are located on both sides of the IGBT body 18, and then start the motor 8, the motor 8 will drive the bidirectional threaded rod 9 to rotate, the bidirectional threaded rod 9 will drive the two connecting blocks 10 to approach each other, and the connecting block 10 will drive the clamping blocks 11 to approach each other, thereby clamping the IGBT body 18, and then start the hydraulic cylinder 5, the hydraulic cylinder 5 will drive the connecting plate 6 and the operating plate 7 to move upward, the operating plate 7 will drive the connecting block 10 and the clamping block 11 to move upward, and the clamping block 11 will drive the IGBT body 18 to move upward, so as to facilitate the IGBT body 18 to be clamped and fixed for detection.
