[0041] In the motor controller of new energy vehicles, the three-phase copper busbar socket needs to pass through the current sensor to connect to the IGBT, and then the three-phase copper busbar socket is connected to the motor to realize the conversion of DC power into AC power for the motor. At present, the connection and positioning of the three are completely dependent on manual alignment and connection, and then placed in the controller housing. However, the manual alignment and connection accuracy is low, which cannot meet the subsequent overall assembly requirements of the controller, and it is very easy to miss the assembly during the assembly process, resulting in rework and low production efficiency.

[0042] The IGBT assembly assembly tooling provided in the present solution is provided with a fixed first support part 2 and a movable second support part 3 on the substrate 1. The first support part 2 positions and supports the first part of the IGBT assembly, namely, the IGBT4. The second support part 3 realizes flexible loading and alignment through a sliding setting, and provides positioning support for the second part of the IGBT assembly, namely, the current sensor 5 or the current sensor 5 and the three-phase copper busbar socket 6 as a whole. The positioning and connection processes are both coordinated with the corresponding limit parts, so that the precise positioning and connection of the IGBT assembly is realized through mechanical support and positioning, thereby ensuring the assembly accuracy of the IGBT assembly and improving the overall assembly and production efficiency of the subsequent motor controller.

[0045] Specifically, in order to solve the problem in the prior art that low positioning accuracy causes rework and affects production efficiency when manually assembling IGBTs and current sensors and three-phase copper busbar sockets, the present application provides an IGBT assembly assembly, in which a fixed first support portion 2 is provided on a substrate 1 to provide stable positioning and support for the first part of the IGBT assembly, and then a movable second support portion 3 is provided in conjunction with the first support portion 2. The second support portion 3 can position and support the second part of the IGBT assembly based on the first support portion 2 and complete the alignment and connection of the first and second parts of the IGBT by movement, thereby effectively improving the assembly accuracy of the IGBT assembly and avoiding errors caused by manual alignment or connection.

[0046] Reference Figure 2 The IGBT assembly targeted in this embodiment includes an IGBT4, a current sensor 5 and a three-phase copper busbar socket 6. Usually, the IGBT4, the current sensor 5 and the three-phase copper busbar socket 6 are arranged in sequence. The three copper bars 61 of the three-phase copper busbar socket 6 pass through the current sensor 5 and are then screwed to the IGBT4. The current sensor 5 is clamped between the IGBT4 and the three-phase copper busbar socket 6. The tooling provided in this embodiment still assembles the IGBT assembly according to the above arrangement and connection method.

[0047] Reference Figure 1 , the substrate 1 is a rigid plate body, which can provide support and installation positions for the first support part 2 and the second support part 3; the shape and size of the substrate 1 can be designed and adjusted according to actual needs, and no further details are given here. The first support part 2 on the substrate 1 can be an additional rigid structure protruding from the surface of the substrate 1, or it can be a mounting area formed directly using the surface of the substrate 1; when the first support part 2 is a structure protruding from the substrate 1, it can be, but not limited to, a structure in the form of a table, a frame, a platform, etc. In this embodiment, the first support part 2 corresponds to the IGBT4 in the IGBT assembly, and it can be understood that the IGBT4 is provided with a pin portion protruding from the surface (not shown in the figure), and then the first limit portion 21 is a hole or groove that can be adapted to the pin portion on the IGBT4, so that the pin portion can be matched to realize the positioning of the IGBT4. In this embodiment, the setting position, setting number, setting shape, and setting size of the first limit portion 21 are all adapted to the pin portion on the IGBT4, and no further restrictions are given here. The first direction a may be any direction on the substrate 1 , such as the length direction or the width direction of the substrate 1 , as long as the first support portion 2 and the second support portion 3 can be installed in the first direction a.

[0048] Reference Figure 1 and attached Figure 2The second supporting portion 3 is a rigid structure, which may be, but is not limited to, a structure in the form of a table, a frame, a platform, etc., and it may slide relative to the base plate 1 through the cooperation of a slide rail and a pulley or a slider. The second supporting portion 3 corresponds to the second part of the IGBT that is positioned and supported. In this embodiment, the second part can be the current sensor 5, or it can be the whole of the current sensor 5 and the three-phase copper busbar socket 6. When the second part is only the current sensor 5, the tooling of this embodiment ensures the precise alignment of the IGBT4 and the current sensor 5, and the alignment and connection accuracy can be guaranteed when the three-phase copper busbar socket 6 is subsequently connected in coordination; it can be understood that the current sensor 5 and the three-phase copper busbar socket 6 are both provided with a pin portion protruding from the surface (not shown in the figure), and then the second limiting portion 21 can be but is not limited to a hole or groove that is compatible with the pin portion, so that the pin portion can be matched to achieve the positioning of the current sensor 5 and the three-phase copper busbar socket 6. In this embodiment, the setting position, setting number, setting shape, and setting size of the second limiting portion 31 are all compatible with the current sensor 5 or the current sensor 5 and the pin portion of the three-phase copper busbar socket 6 as a whole, and no excessive restrictions are made here.

[0049] Reference Figure 1 and attached Figure 2 , the third limiting part 11 cooperates with the fourth limiting part 32 to complete the positioning of the second support part 3. The third limiting part 11 can be a positioning column, a positioning hole, a positioning seat, etc. arranged on the base 1. Correspondingly, the fourth limiting part 32 can be a positioning hole, a positioning column, a positioning pin, etc. that matches it. It can be understood that the third limiting part 11 and the fourth limiting part 32 can be aligned and connected in the direction perpendicular to the substrate 1; in this embodiment, the third limiting part 11 and the fourth limiting part 32 are preferably set in the form of positioning holes, and then the limiting pins are used for artificial locking to ensure the convenience of subsequent demolding operations. In this embodiment, the position selection of the third limiting part 11 needs to meet the requirement that when the second support part 3 is close to the first support part 2 along the first direction a, the third limiting part 11 corresponds to the fourth limiting part 32, and the three copper bars 61 of the three-phase copper bar socket 6 can just correspond to the connection end of the IGBT4. This corresponding relationship can be easily understood by those skilled in the art, and no further elaboration is made here.

[0050] According to the above, the IGBT assembly assembly tooling provided by the present solution is provided with a fixed first support part 2 and a movable second support part 3 on the substrate 1. The first support part 2 positions and supports the first part of the IGBT assembly, namely, the IGBT4. The second support part 3 realizes flexible loading and alignment through a sliding setting, and provides positioning support for the second part of the IGBT assembly, namely, the current sensor 5 or the current sensor 5 and the three-phase copper busbar socket 6 as a whole. The positioning and connection processes are coordinated with the corresponding limit parts, so that the precise positioning and connection of the IGBT assembly is realized through mechanical support and positioning, thereby ensuring the assembly accuracy of the IGBT assembly and improving the overall assembly and production efficiency of the subsequent motor controller.

[0051] Further, see Attachment Figure 2 and attached Figure 3 The IGBT assembly assembly tool provided in this embodiment, in a specific implementation, further includes a protective cover 7, wherein the protective cover 7 is located above the substrate 1; a fifth limiting portion 12 is provided on the substrate 1; a sixth limiting portion 71 adapted to the fifth limiting portion 12 is provided on the protective cover 7, and a plurality of screw openings 72 are provided on the protective cover 7; wherein, when the fifth limiting portion 12 and the sixth limiting portion 71 are connected, the screw openings 72 correspond to the position to be connected between the first part and the second part of the IGBT assembly.

[0052] Specifically, in order to avoid collision with IGBT4 and affect the electrical performance of IGBT4 when the copper busbar 61 and the connecting end of IGBT4 are bolted together, a protective cover 7 is provided in the present embodiment, and the protective cover 7 can play a protective role on the side of each support part facing away from the substrate 1; the protective cover 7 in the present embodiment is a rigid structure, and can be a plate-like structure, a groove-like structure, etc., as long as it can cover each support part. In the present embodiment, the protective cover 7 is preferably set as a groove-like structure, and the groove is set toward the substrate 1 to achieve cover-type protection for each support part; further, screw holes 72 are opened on the protective cover 7, and the number and position of the screw holes 72 correspond to the matching position of the connecting end of the copper busbar 61 and the IGBT4, so that the bolts can be lowered and screwed through the screw holes 72. During this process, hands, bolts, and tools will not touch the IGBT4, thereby effectively avoiding the problem of poor electrical performance of the IGBT due to collision. The fifth limiting portion 12 may be, but not limited to, a positioning column, and the sixth limiting portion 71 may be, but not limited to, a positioning hole or a positioning groove that matches the positioning column. In this embodiment, the fifth limiting portion 12 may be arranged at intervals on the edge of the substrate 1, and the number of arrangements may be designed and adjusted according to actual needs; of course, the fifth limiting portion 12 may be arranged as a positioning hole or a positioning groove, and the sixth limiting portion 71 may be arranged as a positioning column. It is understandable that a flange may be arranged at the edge of the notch of the protective cover 7 to reserve a position for the positioning groove, the positioning hole, or the positioning column.

[0053] Furthermore, in the specific implementation of the IGBT assembly tool provided in this embodiment, the orthographic projection of the protective cover 7 along the second direction b at least completely covers the first supporting portion 2; wherein the second direction b is perpendicular to the surface of the substrate 1.

[0054] Specifically, in order to realize the protective function of the protective cover 7, in this embodiment, the protective cover 7 is set to at least cover the top of the first support part 2, that is, the IGBT 4 is protected separately, which can effectively reduce the weight of the overall tooling while protecting the IGBT 4. Of course, in order to improve the degree of protection, the protective cover 7 can be set to cover both the first support part 2 and the second support part 3 to improve the degree of protection.

[0055] Further, see Attachment Figure 1 and attached Figure 2 In the IGBT assembly assembly tooling provided in this embodiment, in a specific implementation, the second support portion 3 includes a third support portion 33 and a fourth support portion 34; the third support portion 33 and the fourth support portion 34 are arranged in sequence along the first direction a to respectively position and support the current sensor 5 and the three-phase copper busbar socket 6 of the IGBT assembly.

[0056] Specifically, in order to ensure the assembly accuracy of the IGBT assembly, the second support portion 3 in this embodiment is configured to include a third support portion 33 and a fourth support portion 34. The third support portion 33 and the fourth support portion 34 respectively correspond to the positioning support of the current sensor 5 and the three-phase copper busbar socket 6 of the IGBT assembly, thereby enabling the current sensor 5 and the three-phase copper busbar socket 6 to be accurately aligned and connected, thereby greatly improving the assembly accuracy of the IGBT assembly.

[0057] Further, see Attachment Figure 1 In the IGBT assembly tooling provided in this embodiment, in a specific implementation, a force applying portion 8 is provided on a side of the fourth supporting portion 34 away from the third supporting portion 33 along the first direction a.

[0058] Specifically, in order to realize the movement of the third support part 33 and the fourth support part 34, a force-applying part 8 is provided in the present embodiment. The force-applying part 8 is a rigid structure, which may be in the form of but not limited to a handle or a grip. The setting of the force-applying part 8 can provide a holding position or a push-pull position for the movement of the third support part 33 and the fourth support part 34 relative to the first support part 2. The third support part 33 and the fourth support part 34 can be pushed synchronously by the push of the force-applying part 8, thereby avoiding direct contact with human hands to generate external ionic charge that affects the electrical performance of the IGBT4.

[0059] Further, see Attachment Figure 1 and attached Figure 2In the IGBT assembly tooling provided in this embodiment, in a specific implementation, the third support portion 33 and the fourth support portion 34 are both provided with the fourth limiting portion 32; at least two third limiting portions 11 are provided on the substrate 1 along the first direction a to cooperate in positioning the third support portion 33 and the fourth support portion 34.

[0060] Specifically, in order to ensure that the third support portion 33 and the fourth support portion 34 are positioned in place and realize the stable alignment connection of their supporting parts, in this embodiment, a fourth limiting portion 32 is simultaneously provided on the third support portion 33 and the fourth support portion 34, and correspondingly, a third limiting portion 11 corresponding to the third support portion 33 and the fourth support portion 34 is provided on the substrate 1. Of course, it can be understood that the fourth limiting portion 32 on the third support portion 33 and the fourth support portion 34 can be provided on the same side or on two opposite sides, that is, Figure 2 As shown, mutual interference is avoided during positioning; the specific configuration of the third limiting portion 11 and the fourth limiting portion 32 can be referred to the above content and will not be described in detail here.

[0061] Further, see Attachment Figure 1 and attached Figure 2 In the specific implementation of the IGBT assembly tool provided in this embodiment, a first sliding portion 13 is provided on the substrate 1 along the first direction a; and a second sliding portion 35 matched with the first sliding portion 13 is provided on the second supporting portion 3.

The first sliding part 13 can be, but not limited to, a slideway or a slide rail, and the second sliding part 35 can be a corresponding slider or a pulley; accordingly, the first sliding part 13 can be a slider or a pulley, and the second sliding part 35 can be a slideway or a slide rail. In this embodiment, two first sliding parts 13 can be provided in parallel to ensure the stable sliding of the second support part 3.

[0067] Specifically, in order to ensure the electrical performance of the IGBT assembly, an ion blower 91 is provided in this embodiment, which can blow out positive and negative ion charges alternately to neutralize the ion charges on the IGBT 4. Even if the operator charges the IGBT 4 when positioning and supporting the IGBT 4 and the first support portion 2, the ion blower 91 can neutralize the ion charges, thereby effectively ensuring the electrical performance of the IGBT assembly. It can be understood that a power supply device (not shown in the figure) for the ion blower 91 needs to be provided on or under the rack 9.
