Description

Technical Field

[0001] This application relates to the technical field of IGBT manufacturing, and particularly relates to a terminal bending device based on IGBT electronic components. Background Technique

[0002] IGBT, the full Chinese name is Insulated Gate Bipolar Transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (Bipolar Junction Transistor) and MOS (Insulated Gate Field Effect Transistor). During the production and assembly process of IGBT modules, it is necessary to bend the terminals of IGBT electronic components by 90 degrees.

[0003] Currently, the existing terminal bending devices for IGBT electronic components cannot accurately control the bending angle during use, which easily affects the quality of the finished product after bending, and the efficiency of the bending work is very low. At the same time, during the bending work, the terminals of IGBT electronic components cannot be effectively fixed, resulting in damage to the terminals of IGBT electronic components during the bending work, increasing the cost investment in the bending work. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technique, this application provides a terminal bending device based on IGBT electronic components.

[0005] A terminal bending device based on IGBT electronic components provided by this application adopts the following technical solutions: It includes a base plate. One end of the upper surface of the base plate is fixedly provided with a first support rod. The top of the first support rod is fixedly provided with an outer sleeve. A semi-circular sliding plate is slidably arranged at the bottom of the inner wall of the outer sleeve. One end of the bottom of the semi-circular sliding plate is fixedly provided with a vertical plate and is slidably connected to the chute in the middle of the outer sleeve. The bottom of the vertical plate is fixedly provided with a trapezoidal slider, and the bottom of the trapezoidal slider is slidably arranged on the inner wall of the trapezoidal chute on the upper surface of the base plate.

[0006] One end of the inner wall of the semi-circular sliding plate is fixedly provided with an annular groove. A corner plate is slidably arranged on the inner wall of the annular groove. One end of the corner plate away from the annular groove is fixedly provided with a rotating disc. The middle of the inner side of the rotating disc is fixedly provided with a middle rotating column.

A vertical baffle is arranged on the outer side of the 90-degree bending plate and is horizontally arranged with the base plate.

[0007] Optionally, the number of annular grooves is two. The middle between the two annular grooves is communicated through a rectangular groove. The inner wall width of the annular groove is greater than the thickness of the rotating disc.

[0008] Optionally, a second support rod is fixedly arranged at the right end of the upper surface of the base plate. The top of the second support rod is fixedly provided with a load-carrying plate. A limiting plate is slidably arranged at the right end of the inner wall of the load-carrying plate. A bolt rod is arranged on the right side of the limiting plate and is threadedly connected to the right side of the load-carrying plate. The load-carrying plate is higher than the upper surface of the ninety-degree bending plate and is vertically arranged with respect to it.

[0009] Optionally, an arc-shaped track is spirally arranged on the surface of the middle rotating column, and the arc-shaped track has the same diameter as the sliding cylinder.

[0010] Optionally, a telescopic rod is fixedly arranged on the inner wall of the power groove in the middle of the semi-circular sliding plate.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] 1. By setting the middle rotating column and the arc-shaped track on its surface and other components in the present utility model, the rotating column drives the rotating disc and the ninety-degree bending plate to displace under the action of power. The circular ring groove restricts the displacement of the middle rotating column through the corner plate, and the middle rotating column is urged to flip through the arc-shaped track, realizing the change of angle, achieving the effect of changing the angle after moving the ninety-degree bending plate to a certain extent, and realizing the bending treatment of the terminals on the surface of the load-carrying plate.

[0015] 2. By arranging components such as a limiting plate and a bolt rod inside the load-carrying plate in the present utility model, the limiting plate is made to approach and move away from the terminal by rotating the bolt rod, realizing the fixation of the terminal, avoiding shaking during the bending process, ensuring the stability of the bending work, reducing the defective products generated during the bending work, reducing the cost investment of the terminals for producing IGBT electronic components, and reducing the manual operation of the terminals.

Detailed implementation manners

[0021] The following further Figures 1-4 describes the present application in detail with reference to the attached

[0022] The embodiment of the present application discloses a terminal bending device based on IGBT electronic components. As Figure 1 shown, it includes a base plate 1. A second support rod 7 is fixedly arranged at the right end of the upper surface of the base plate 1. The second support rod 7 provides support for the load plate 10. The load plate 10 is fixedly arranged at the top of the second support rod 7. A limiting plate 22 is slidably arranged at the right end of the inner wall of the load plate 10. The limiting plate 22 facilitates the clamping and fixing of the side of the terminal and limits its position. A bolt rod 9 is arranged on the right side of the limiting plate 22 and is threadedly connected to the right side of the load plate 10. The bolt rod 9 facilitates driving the limiting plate 22 to move. The load plate 10 is higher than the upper surface of the ninety-degree bending plate 8 and is vertically arranged with it. A first support rod 2 is fixedly arranged at one end of the upper surface of the base plate 1. An outer sleeve 15 is fixedly arranged at the top of the first support rod 2. A semi-circular sliding plate 17 is slidably arranged at the bottom of the inner wall of the outer sleeve 15. One end of the bottom of the semi-circular sliding plate 17 is fixedly provided with a vertical plate 5 and is slidably connected to the chute in the middle of the outer sleeve 15.

[0023] Please refer to Figure 1 , a hydraulic rod 4 is fixedly arranged in the middle of one side of the vertical plate 5. The end of the hydraulic rod 4 away from the vertical plate 5 is fixedly provided with a support plate 3. The bottom of the support plate 3 is fixedly arranged on the upper surface of the base plate 1. The hydraulic rod 4 is arranged on one side of the vertical plate 5. The telescopic movement of the hydraulic rod 4 provides power for the vertical plate 5 and the semi-circular sliding plate 17 at the top. A trapezoidal slider 6 is fixedly arranged at the bottom of the vertical plate 5. The bottom of the trapezoidal slider 6 is slidably arranged on the inner wall of the trapezoidal chute on the upper surface of the base plate 1.

[0024] Please refer to Figure 1, the number of the circular grooves 14 is two. The middle part between the two circular grooves 14 is communicated through a rectangular groove 23. The inner wall width of the circular groove 14 is greater than the thickness of the rotating disc 12. Connecting the two circular grooves 14 through the rectangular groove 23 facilitates the rotational displacement of the corner plate 18 after changing the angle of the middle rotating column 16, and avoids movement conflicts.

[0025] Please refer to Figure 1 , one end of the inner wall of the semi-circular slide plate 17 is fixedly provided with a circular groove 14. A corner plate 18 is slidably arranged on the inner wall of the circular groove 14. The number of the corner plates 18 is two. The two corner plates 18 are symmetrically arranged on the outer side of the rotating disc 12. Arranging two corner plates 18 on the outer side of the rotating disc 12 ensures that the rotating disc 12 can slide smoothly. The distance between the two corner plates 18 is less than the distance between the two rectangular grooves 23, avoiding jamming when the rotating disc 12 moves. One end of the corner plate 18 away from the circular groove 14 is fixedly provided with a rotating disc 12. The middle part of the inner side of the rotating disc 12 is fixedly provided with a middle rotating column 16. An arc-shaped track 13 is spirally arranged on the surface of the middle rotating column 16. The arc-shaped track 13 on the surface of the middle rotating column 16 facilitates the connection with the sliding cylinder 20 to form a complete power structure. The outer wall of the middle rotating column 16 is slidably connected with the inner wall of the semi-circular slide plate 17. A connecting column 11 is fixedly arranged on the outer side of the rotating disc 12. The end of the connecting column 11 is fixedly provided with a ninety-degree bending plate 8. A vertical baffle is arranged on the outer side of the ninety-degree bending plate 8 and is horizontally arranged with the base plate 1.

[0026] Please refer to Figure 2 , a telescopic rod 19 is fixedly arranged on the inner wall of the power groove in the middle of the semi-circular slide plate 17. The other end of the telescopic rod 19 is fixedly provided with a baffle 21. A sliding cylinder 20 is fixedly arranged on the side of the baffle 21 away from the telescopic rod 19. One end of the sliding cylinder 20 away from the baffle 21 is slidably connected with the arc-shaped track 13 on the surface of the middle rotating column 16. During the telescopic process of the telescopic rod 19, the sliding cylinder 20 is driven to move through the baffle 21, avoiding obstruction when disassembling the middle rotating cylinder 16 and facilitating the maintenance and repair of the device.

[0027] The implementation principle of a terminal bending device based on IGBT electronic components in an embodiment of this application is as follows: Place the terminal of the IGBT electronic component to be bent on the upper surface of the loading plate 10. Rotate the bolt rod 9 to make the limiting plate 22 move closer to the terminal of the IGBT electronic component, thereby fixing the terminal of the IGBT electronic component. At the same time, the bending position of the terminal of the IGBT electronic component is located at the outer end of the loading plate 10 and above the ninety-degree bending plate 8. Start the hydraulic rod 4 as the power to drive the semi-circular sliding plate 17 to move. The sliding cylinder 20 inside the semi-circular sliding plate is slidably connected to the arc-shaped track 13 on the surface of the middle rotating column 16. Then the middle rotating column 16 moves simultaneously in translation. The middle rotating column 16 drives the ninety-degree bending plate 8 to move through the rotating disc 12 and the connecting column 11. When the corner plate 18 on the side of the rotating disc 12 contacts the inner circular ring groove 14, at this time, the rotating disc 12 cannot move in translation. However, the surface of the middle rotating column 16 is provided with an arc-shaped track. During the continuous movement of the semi-circular sliding plate 17, the middle rotating column 16 rotates. At the same time, the ninety-degree bending plate 8 at one end flips. During the flipping process of the ninety-degree bending plate 8, the terminal of the IGBT electronic component is bent.

[0028] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
