In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components can be exaggerated or reduced.

[0063] In this document, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of" when following a list of elements, modify the entire list of elements and not the individual elements of the list. For example, the expression "at least one of a, b, and c" should be understood as including only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0064] The terminology used herein is for the purpose of describing particular example configurations only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" can be intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0066] It is found through research that in the related art, the manipulator carries the IGBT module to the moving module, the moving module drives the IGBT module to move horizontally to the pin insertion station, and the pin insertion device inserts the pin into the specified position of the IGBT module. However, during the pin insertion process, there is a gap between the IGBT module and the bearing position of the moving module, so that during the pin insertion process of the IGBT module, the pin insertion precision is not high, thereby affecting the pin insertion quality. The traditional positioning device compresses and positions the IGBT module after the IGBT module is placed in the bearing position, but the above-mentioned method needs a certain reaction time when the traditional positioning device clamps and releases the IGBT module during the taking and placing of the IGBT module, thereby reducing the work efficiency. Therefore, how to avoid the displacement of the IGBT module is a technical problem to be solved in the field. The defects of the above-mentioned scheme and the causes thereof are the results obtained by the inventors after practice and careful research, and therefore the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure for the above-mentioned problems should be the contributions made by the inventors to the present disclosure in the process of the present disclosure.

[0067] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0068] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0069] like Figures 1 to 6 As shown, at least one embodiment provides an IGBT pin positioning device, comprising:

[0070] A movable module 1 is mounted on a workbench and is adapted to drive the IGBT module to move horizontally. The movable module 1 includes a front-to-back sliding joint 16 and a left-to-right sliding joint 17. The front-to-back sliding joint 16 is horizontally mounted on the workbench, and a slide rail 18 parallel to the front-to-back sliding joint 16 is also provided on the workbench. The front-to-back sliding joint 16 is adapted to drive the slide plate 19 to move back and forth. The left-to-right sliding joint 17 is mounted on the slide plate 19 of the front-to-back sliding joint 16, and the direction of movement of the sliding block 10 is perpendicular to the direction of movement of the slide plate 19.

[0071] Reference Appendix Figure 2 The system includes two positioning modules 2, which are hinged to the outer wall of the movable slider 10 of the movable module 1. A linkage module 3 is vertically mounted within the movable slider 10 and is linked to the two positioning modules 2. When the IGBT module presses the linkage module 3 downwards, the linkage module 3 is adapted to push the positioning modules 2 to flip, thus clamping the IGBT module. Through the cooperation of the positioning modules 2, linkage module 3, and movable slider 10, during the process of placing the IGBT module into the movable slider 10, the linkage module 3 is pushed downwards, while the two positioning modules 2 simultaneously flip to clamp the IGBT module. When removing the IGBT module, the robotic arm 6 pushes the positioning modules 2 to flip outwards, and the positioning modules 2 drive the linkage module 3 to move upwards, facilitating the robotic arm 6 to grip the IGBT module. This not only improves the stability of the IGBT module on the movable slider 10 but also enhances the convenience of gripping the IGBT module.

[0072] Reference Appendix Figure 3, the positioning module 2 includes: a fixed block 21, which is arranged on the outer wall of the mobile slider 10 and is provided with a positioning groove 20; a rotating shaft 22, which is rotatably arranged in the positioning groove 20; an upper positioning rod 23, one end of which is arranged on the outer wall of the rotating shaft 22 and the other end extends upward above the mobile slider 10; and a lower positioning rod 24, one end of which is arranged on the outer wall of the rotating shaft 22 and the other end abuts against the bottom wall of the linkage module 3; when the IGBT module is not placed on the mobile slider 10, the linkage module 3 moves upward to protrude above the upper surface of the mobile slider 10, at this time, the two upper positioning rods 23 are respectively turned outward, and the spacing between the two upper positioning rods 23 is greater than the outer diameter of the IGBT module, so that the IGBT module can be horizontally placed on the mobile slider 10. Wherein, when the manipulator 6 clamps the IGBT module horizontally and places it on the mobile slider 10, the linkage module 3 is pressed to move downward, the linkage module 3 pushes the lower positioning rod 24 to turn downward, and the lower positioning rod 24 drives the rotating shaft 22 to rotate, so that the upper positioning rod 23 is synchronously turned to the direction of the mobile slider 10, so as to press the IGBT module.

A spring is arranged in the adjusting groove 13, one end of the spring abuts against the adjusting rod 14, and the spring is adapted to push the adjusting rod 14 to move outward. When the IGBT module pushes the lifting column 32 to retract in the containing groove 11, the adjusting rod 14 abuts against the outer wall of the upper cone 34, at this time, the adjusting rod 14 is adapted to limit the upper cone 34, preventing the lifting column 32 from being pushed upward by the reset spring 33. When the IGBT module needs to be taken out, the manipulator 6 expands outward, pushes the two upper positioning rods 23 to turn outward about the rotating shaft 22, at this time, the lower positioning rod 24 is synchronously turned upward to push the lifting column 32 to move upward, and in the process of moving upward, the lifting column 32 pushes the adjusting rod 14 to retract in the adjusting groove 13, until the end of the adjusting rod 14 abuts against the outer wall of the lower cone 35.

[0074] Refer to the accompanying drawings Figure 4 , the mobile slider 10 is provided with a containing groove 11 in the axial direction, and the linkage module 3 is arranged in the containing groove 11; the mobile slider 10 is provided with a turning opening 12 in the radial direction, the turning opening 12 communicates with the containing groove 11, and the lower positioning rod 24 is arranged in the turning opening 12.
