TECHNICAL FIELD

[0001] The utility model relates to positioning processing equipment technical field especially, relates to a kind of positioning tooling and power module processing platform. BACKGROUND

[0002] The power module of new energy automobile needs positioning tooling to support, so that the surface of power module needs to be machined is planar, ensure the processing quality of power module in subsequent processing process. Since multiple surfaces of power module need to be processed, multiple surfaces of power module need to be processed, but since the flatness of different planes is different, when the flatness of plane is poor, it will directly lead to the processing effect of power module is poor, thereby affecting the subsequent use of power module. SUMMARY

[0003] Therefore, the positioning tooling and power module processing platform are provided, and the above technical problems are solved by improving the structure of the positioning tooling.

[0004] The first aspect of the embodiment of the application provides a positioning tooling, which comprises a base, a first positioning assembly and a second positioning assembly. The base has a first positioning position and a second positioning position arranged at intervals. The first positioning assembly is installed at the first positioning position, and the second positioning assembly is installed at the second positioning position. The second positioning assembly comprises a positioning member and an adjusting member. One end of the positioning member is connected to the base. The second positioning assembly has a first positioning state and a second positioning state. The positioning member has a first height position and a second height position relative to the base. When the second positioning assembly is in the first positioning state, the adjusting member is located at the first height position. When the second positioning assembly is in the second positioning state, the adjusting member is located at the second height position. The first height position is closer to the base than the second height position.

[0005] In the application, the position of the adjusting member relative to the positioning member is adjusted to adjust the height of the second support surface of the second positioning assembly relative to the base. Thus, the different support states of the power module are adapted. Since the position of the adjusting member relative to the positioning member can be moved in the application, the distance between the second support surface of the positioning tooling and the base can be adjusted by adjusting the adjusting member regardless of the flatness of the surface of the power module supported. In this way, the positioning tooling can be adapted to different processing processes of the power module. In other words, the same positioning tooling can adaptively support multiple surfaces of the power module to ensure that the machined surface of the power module is planar, the machined surface of the power module is parallel to the plane in which the base is located, and thus the processing quality of the power module in subsequent processing operations is ensured.

[0006] The second aspect of the embodiment of the application provides a power module processing platform, which comprises the positioning tooling of the first aspect of the embodiment of the application.

[0007] Since the main beneficial effects of the second aspect are derived from the beneficial effects of the first aspect, the beneficial effects of the second aspect are specifically referred to the beneficial effects of the first aspect, which will not be repeated here.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should belong to the protection scope of the present application.

[0024] Unless otherwise defined, the technical terms or scientific terms used herein should have the meanings generally understood by those skilled in the art to which the present application belongs. The "one", "a" or "the" and similar words used in the present application do not represent quantity limitation, but only represent the existence of at least one. "Include" or "contain" and similar words mean that the elements or objects before the words cover the elements or objects listed after the words and their equivalents, without excluding other elements or objects. "Connected" or similar words are not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect.

[0025] Reference to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment. The appearances of the phrase“in one embodiment” in various places in the specification are not necessarily referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments.

[0026] The drawings of the embodiments of the present application will be described below in conjunction with the Figures 1-11 The technical solutions in the embodiments of the present application are described clearly and completely, and it should be noted that the height direction Z indicated in each drawing is referenced to the height direction of the positioning tool 1, and the directions indicated in each drawing are uniform to facilitate the reference and understanding of the readers.

[0027] Please refer to Figure 1 The present application provides a power module processing platform 1000, which comprises a positioning tool 1 for supporting a power module 2 to ensure the processing quality of the power module 2 processed by the power module processing platform 1000.

[0028] It should be understood that, since the front and back surfaces of the power module 2 of the new energy vehicle have pin rows, the power module 2 cannot be directly supported by a desktop plane. In the existing mode, the power module 2 is supported by the positioning tool 1. The positioning tool 1 can form a support surface spaced from the plane where the base 10 is located. When the power module 2 is placed on the positioning tool 1, the support column of the positioning tool 1 supports the power module 2, so that the supported surface of the power module 2 is located on the support surface of the positioning tool 1, and the surface to be processed of the power module 2 needs to be a horizontal plane. However, since the height planes of the surfaces of different regions in the power module 2 are different, different specifications of the positioning tool 1 need to be used when the power module 2 is processed to ensure that each surface to be processed of the power module 2 can be a horizontal plane and ensure the processing quality of any surface of the power module 2.

[0029] Therefore, please refer to Figures 2 to 9 The present application also provides a positioning tool 1 for supporting a power module 2. The positioning tool 1 can be applied to the aforementioned power module processing platform 1000 and can also be used independently.

[0030] Specifically, the positioning fixture 1 includes a base 10, a first positioning assembly 11, and a second positioning assembly 12. The base 10 has a first positioning position 100 and a second positioning position 101 spaced apart. The first positioning assembly 11 is installed at the first positioning position 100 to support the first portion 200 of the power module 2. The second positioning assembly 12 is installed at the second positioning position 101. The first positioning assembly 11 is used to support the first portion 200 of the power module 2, and the second positioning assembly 12 is used to support the second portion 201 of the power module 2.

[0031] In other words, on the bottom plate of the positioning tool 1, the first positioning component 11 at the first positioning position 100 corresponds to the first part 200 supporting the power module 2, and the second positioning component 12 at the second positioning position 101 corresponds to the second part 201 supporting the power module 2. In this way, the power module 2 can be supported on the supporting surface separated from the base 10, thereby preventing the pins on the surface of the power module 2 from being squeezed and deformed due to touching the base 10.

[0032] Take the glue filling process of power module 2 as an example to illustrate. Figure 3 The power module 2 shown includes a first portion 200 and a second portion 201. The surfaces to be processed are the first and second surfaces of the power module 2, which are arranged opposite to each other. Before the glue filling operation is performed on the power module 2, the power module 2 needs to be placed on the positioning fixture 1 so that the first or second surface of the power module 2 is horizontal to ensure that the glue can be spread flat on the first or second surface during the glue filling operation. When the first surface of the power module 2 is placed toward the base 10, the second surface can be horizontal to the plane of the base 10. Therefore, at this time, the support surface of the first positioning component 11 and the support surface of the second positioning component 12 are set at the same height; when the second surface of the power module 2 is placed toward the base 10, to ensure that the first surface can be horizontal to the plane of the base 10, in the power module 2, there is a height difference between the surface of the first portion 200 facing the base 10 and the surface of the second portion 201 facing the base 10. Therefore, to accommodate this height difference, there is a height difference between the support surface of the first positioning component 11 and the support surface of the second positioning component 12.

[0033] It should be understood that the support surface of the first positioning component 11 and the support surface of the second positioning component 12 are set at the same height. In other words, the height distance between the support surface of the first positioning component 11 and the base 10 is the same as the height distance between the support surface of the second positioning component 12 and the base 10. There is a height difference between the support surface of the first positioning component 11 and the support surface of the second positioning component 12. In other words, the height distance between the support surface of the first positioning component 11 and the base 10 is different from the height distance between the support surface of the second positioning component 12 and the base 10.

[0034] To meet the above processing needs, the second positioning assembly 12 of the positioning tool 1 in the present application includes a positioning member 120 and an adjusting member 121. One end of the positioning member 120 is connected to the base 10 to ensure the connection relationship between the second positioning assembly 12 and the base 10.

[0035] The second positioning assembly 12 has a first positioning state and a second positioning state to match different support needs of the power module 2. The positioning member 120 has a first height position d1 and a second height position d2 relative to the base 10 to match different support surfaces of the power module 2, so that the surface to be processed of the power module 2 can be in a flat state.

[0036] When the second positioning assembly 12 is in the first positioning state (for reference Figure 3 and Figure 4 ), the adjusting member 121 is located at the first height position d1. When the second positioning assembly 12 is in the second positioning state (for reference Figure 5 and Figure 6 ), the adjusting member 121 is located at the second height position d2. The first height position d1 is closer to the base 10 than the second height position d2.

[0037] It should be understood that due to the structural characteristics of the power module 2, if the first positioning assembly 11 and the second positioning assembly 12 have the same height, the surface of the power module 2 cannot necessarily be parallel to the plane of the base after the power module 2 is supported. For reference Figures 4 to 7 , in Figure 4 , the positioning tool 1 supports the first surface of the power module 2, and the second surface of the power module 2 is the surface to be processed; in Figure 6 , the positioning tool 1 supports the second surface of the power module 2, and the first surface of the power module 2 is the surface to be processed. It should be understood that the first surface and the second surface of the power module 2 are arranged opposite to each other.

[0038] Specifically, in Figure 4 , the plane of the power module 2 that needs to be supported is the first surface, and the adjusting member 121 in the second positioning assembly 12 is located at the second height position d2. By setting the height of the first support surface 110 of the first positioning assembly 11 to be the same as the height of the second support surface 1203 of the second positioning assembly 12, the second surface of the power module 2 is parallel to the plane of the base 10. In Figure 5 , the plane of the power module 2 that needs to be supported is the second surface, and the adjusting member 121 in the second positioning assembly 12 is located at the first height position d1. By setting the height of the first support surface 110 of the first positioning assembly 11 to be lower than the height of the second support surface 1203 of the second positioning assembly 12, the first surface of the power module 2 is parallel to the plane of the base 10.

[0039] Therefore, in the present application, by adjusting the position of the adjusting member 121 relative to the positioning member 120, the height of the second support surface 1203 in the second positioning assembly 12 relative to the base 10 is adjusted, so that the different support states of the power module 2 are adapted. Since the position of the adjusting member 121 relative to the positioning member 120 in the present application can be moved, regardless of the flatness of the surface on which the power module 2 is supported, the distance between the second support surface 1203 of the positioning tool 1 and the base 10 can be adjusted by adjusting the adjusting member 121 at this time. Therefore, the positioning tool 1 can be adapted to different processing processes of the power module 2. In other words, the same positioning tool 1 can adaptively support multiple surfaces of the power module 2 to ensure that the processed surface of the power module 2 is planar, ensuring that the processed surface of the power module 2 is parallel to the plane in which the base 10 is located, and further ensuring the processing quality of the power module 2 in the subsequent processing operation.

[0040] It should be noted that the flatness of the surface of the power module 2 generally refers to the shape of the surface. Specifically, the flatness of the surface can refer to the concave-convex condition of the surface, the height difference condition of different parts of the surface, etc. In the present application, no range is limited.

[0041] In the existing positioning tool 1 product, the positioning assembly provided thereon does not have a support surface adjusting function, and the distance between the support surface and the base 10 is fixed. Therefore, when the surface of the power module 2 is processed, different specifications of the positioning tool 1 need to be replaced according to the flatness of the surface of the power module 2, which not only wastes time but also increases the consumption cost (such as material cost, processing time cost, etc.) of the power module 2 in the processing process. The positioning tool 1 in the present application can avoid the above problems by adjusting the position of the adjusting member 121, thereby reducing the material cost and time cost in the processing process of the power module 2, while ensuring the processing quality of the power module 2, and effectively improving the processing efficiency of the power module 2.

[0042] In some embodiments, the first positioning assembly 11 also includes a positioning member 120 and an adjusting member 121. In other words, the first positioning assembly 11 and the second positioning assembly 12 have the same structural features although they are installed at different positioning positions of the base 10. The support height that can be formed by the first positioning assembly 11 can also be adjusted by adjusting the adjusting member 121 installed on the positioning member 120 thereof.

[0043] Alternatively, the first positioning assembly 11 has the same structure as the second positioning assembly 12. Therefore, the first support surface 110 in the first positioning assembly 11 can also be close to or away from the base 10, thereby increasing the support adaptability between the positioning tool 1 and the power module 2.

[0044] For referenceFigure 5 、 Figure 7 and Figure 9 Further, the positioning member 120 comprises a base mounting portion 1200 and an adjustment mounting portion 1201 connected to each other, the base mounting portion 1200 is connected to the base 10 to ensure the connection relationship between the positioning member 120 and the base 10, and the adjustment mounting portion 1201 is connected to the adjustment member 121 to ensure the connection relationship between the adjustment member 121 and the positioning member 120.

[0045] The adjustment mounting portion 1201 is formed with a first height position d1 and a second height position d2 to match different support requirements of the positioning tool 1.

[0046] The adjustment member 121 is movably connected to the adjustment mounting portion 1201, when the second positioning assembly 12 is switched from the first positioning state to the second positioning state, the adjustment member 121 moves along the adjustment mounting portion 1201, and the height of the adjustment member 121 is moved from the first height position d1 to the second height position d2 to adapt to the support requirements of the power module 2.

[0047] Therefore, in the embodiment of the part, since the adjustment member 121 is movably connected to the adjustment mounting portion 1201, the adjustment member 121 has a moving function along the adjustment mounting portion 1201, by adjusting the position of the adjustment member 121 on the adjustment mounting portion 1201, the distance between the adjustment member 121 and the base 10 is adjusted, so that the distance between the second support surface 1203 and the base 10 is adjusted, and the positioning tool 1 is adapted to the support requirements of the power module 2.

[0048] Please refer to Figure 5 、 Figure 7 and Figure 9 Further, the first positioning assembly 11 is provided with a first support surface 110 on the side away from the base 10, and the adjustment member 121 is provided with a second support surface 1203 on the side away from the base 10, when the second positioning assembly 12 is in the first positioning state, the first support surface 110 and the second support surface 1203 are arranged in parallel along the height direction Z of the positioning tool 1, when the second positioning assembly 12 is in the second positioning state, the first support surface 110 and the second support surface 1203 are arranged staggered along the height direction Z of the positioning tool 1, and the distance between the first support surface 110 and the base 10 is smaller than the distance between the second support surface 1203 and the base 10.

[0049] Therefore, the first support surface 110 and the second support surface 1203 can adaptively support different surfaces of the power module 2, so as to ensure that the surface to be machined of the power module 2 is placed parallel to the surface of the base 10, thereby ensuring the flatness of the surface to be machined of the power module 2.

[0050] Please refer to Figures 3 to 9Further, the first positioning assembly 11 comprises a first column 111 and a second column 112, the second column 112 has a cross-sectional dimension greater than that of the first column 111, and a first supporting surface 110 is formed at the junction of the first column 111 and the second column 112; the first column 111 is configured to pass through a first positioning through-hole 2000 on the substrate 20 of the power module 2, and the first supporting surface 110 is configured to abut against a first portion 200 of the substrate 20 of the power module 2.

[0051] In this way, the first column 111 passes through the first positioning through-hole 2000, so that the first positioning assembly 11 can position the substrate 20 to a certain extent. In the direction of the plate body of the substrate 20, the first column 111 forms a constraint on the substrate 20 in the direction of the aperture of the first positioning through-hole 2000, so that the substrate 20 is difficult to move in the direction of the aperture of the first positioning through-hole 2000. When the positioning tool 1 supports the power module 2, the power module 2 can be stably supported on the positioning tool 1.

[0052] Referring again to Figures 4 to 9 Optionally, the second positioning assembly 12 comprises a third column 122 and a fourth column 123, the fourth column 123 has a cross-sectional dimension greater than that of the third column 122, and a limiting surface is formed at the junction of the third column 122 and the fourth column 123; an adjusting mounting portion 1201 is arranged on the third column 122, and a second supporting surface 1203 is formed on the surface of the adjusting member 121 away from the limiting surface; the third column 122 is configured to pass through a second positioning through-hole 2010 on the substrate 20 of the power module 2, and the second supporting surface 1203 is configured to abut against a second portion 201 of the substrate 20 of the power module 2.

[0053] In this way, the third column 122 passes through the second positioning through-hole 2010, so that the second positioning assembly 12 can position the member 120 to a certain extent. In the direction of the plate body of the substrate 20, the third column 122 forms a constraint on the substrate 20 in the direction of the aperture of the second positioning through-hole 2010, so that the substrate 20 is difficult to move in the direction of the aperture of the second positioning through-hole 2010. When the positioning tool 1 supports the power module 2, the power module 2 can be stably supported on the positioning tool 1.

[0054] In an embodiment, the first positioning assembly 11 comprises a first column 111 and a second column 112, the cross-sectional dimension of the second column 112 is larger than that of the first column 111, and a first supporting surface 110 is formed at the junction of the first column 111 and the second column 112; the first column 111 is configured to pass through a first positioning through-hole 2000 formed on the substrate 20 of the power module 2, and the first supporting surface 110 is configured to abut against a first portion 200 of the substrate 20 of the power module 2. The second positioning assembly 12 comprises a third column 122 and a fourth column 123, the cross-sectional dimension of the fourth column 123 is larger than that of the third column 122, and a limiting surface is formed at the junction of the third column 122 and the fourth column 123; an adjusting mounting portion 1201 is arranged on the third column 122, and a second supporting surface 1203 is formed on the surface of the adjusting member 121 away from the limiting surface; the third column 122 is configured to pass through a second positioning through-hole 2010 formed on the substrate 20 of the power module 2, and the second supporting surface 1203 is configured to abut against a second portion 201 of the substrate 20 of the power module 2.

[0055] Thus, in the plate body extension direction of the substrate 20, the first column 111 forms a constraint on the substrate 20 along the aperture direction of the first positioning through-hole 2000 at the first portion 200 of the substrate 20, and the third column 122 forms a constraint on the substrate 20 along the aperture direction of the second positioning through-hole 2010 at the second portion 201 of the substrate 20, so that the positioning tool 1 forms a positioning constraint on the substrate 20 at different positions, and the substrate 20 can be stably supported on the surface of the positioning tool 1, so that the power module 2 can be stably placed on the surface of the positioning tool 1 when the surface of the power module 2 is machined, thereby ensuring the processing quality of the power module 2.

[0056] It should be further noted that when the aperture of the first positioning through-hole 2000 matches the outer diameter of the first column 111, and the aperture of the second positioning through-hole 2010 matches the outer diameter of the third column 122, if there is a height difference between the first supporting surface 110 formed on the first positioning assembly 11 and the second supporting surface 1203 formed on the second positioning assembly 12, for example, the first supporting surface 110 is higher than the second supporting surface 1203, then when the first column 111 passes through the first positioning through-hole 2000 and the third column 122 passes through the second positioning through-hole 2010, the first portion 200 of the substrate 20 can abut against the first supporting surface 110, and if the gravity of the substrate 20 is not considered, the second portion 201 of the substrate 20 cannot abut against the second supporting surface 1203, but due to the gravity of the substrate 20 itself, the substrate 20 will bend towards the position of the second supporting surface 1203, at this time, the surface of the substrate 20 will bend towards the direction of the second supporting surface 1203, and the surface to be machined of the power module 2 will bend along with the bending of the substrate 20, thereby affecting the processing quality of the power module 2.

[0057] Therefore, in the embodiments of this part, the setting of the adjusting member 121 enables the positioning tool 1 to adjust the second supporting surface 1203 in this case, so that the substrate 20 abuts against the second supporting surface 1203, thereby ensuring the flatness of the surface to be processed of the power module 2 and improving the processing quality of the power module 2.

[0058] For reference Figure 9 Optionally, the outer periphery of the adjusting mounting portion 1201 is provided with a threaded structure, the adjusting member 121 is a threaded sleeve, the adjusting member 121 is connected with the threaded structure, so that the adjusting member 121 is threadedly connected with the adjusting mounting portion 1201. In this way, the adjusting member 121 is movably connected with the adjusting mounting portion 1201, and when the position of the adjusting member 121 relative to the positioning member 120 is adjusted, the adjusting member 121 does not need to be detached from the positioning member 120, and the position of the adjusting member 121 can be adjusted by rotating the adjusting member 121, so as to adjust the height of the second supporting surface 1203 formed on the adjusting member 121 relative to the base 10, so as to adaptively support the power module 2. In this way, the situation that the adjusting member 121 is lost due to being detached from the adjusting mounting portion 1201 can be reduced, the service life of the positioning tool 1 is ensured, and the support demand of the positioning tool 1 can also be met.

[0059] For reference Figure 5 , Figure 7 and Figure 9 Further, the second positioning assembly 12 further comprises a locking nut 124, the locking nut 124 is connected with the adjusting mounting portion 1201, and in the height direction Z of the positioning member 120, the locking nut 124 is located between the adjusting member 121 and the base 10.

[0060] The locking nut can be loosened or tightened on the adjusting mounting portion 1201 in different rotating directions. In other words, when the locking nut is rotated in a first rotating direction, the locking nut is loosened on the adjusting mounting portion 1201, and the locking nut can move in the extension direction of the adjusting mounting portion 1201. When the locking nut is rotated in a second rotating direction, the locking nut is tightened on the adjusting mounting portion 1201, and the locking nut can form a limiting supporting action on the adjusting member 121, so as to avoid the movement of the adjusting member 121 in the direction of the adjusting mounting portion 1201 during the supporting process of the positioning tool 1 on the power module 2, so that the positioning tool 1 can stably support the power module 2.
