Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a battery pack top cover clamping fixture. Background Technology

[0002] In the assembly process of new energy power battery packs, the top cover and lower shell of the battery pack need to be fitted and pressed together to ensure that the sealing surfaces of the two are evenly fitted and the assembly gaps are consistent, thus avoiding assembly defects such as misalignment and warping during subsequent sealing and bolt fastening processes. The battery pack top cover pressing fixture, as a dedicated positioning and pressure application device on the assembly line, mainly relies on the pressing components to apply uniform pressure from above the top cover, stably limiting the displacement and deformation of the top cover during the assembly process.

[0003] In current technology, most mainstream clamping fixtures in the industry are fixed, integrated structures. The overall installation position of the fixture cannot be flexibly moved or adjusted laterally or longitudinally, and it can only be used for battery pack top covers of a single size, making it difficult to be compatible with multiple battery pack products of different lengths, widths, and dimensions. When changing production lines, the entire fixture must be replaced, resulting in lengthy line changes. Furthermore, the clamping and pressure-applying components of the fixture are mostly fixed using bolts and welding, making disassembly and assembly cumbersome and not supporting quick replacement. The overall fixture has poor versatility, significantly increasing production costs and time. Summary of the Invention

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] It is worth noting that during the assembly process of new energy power battery packs, the top cover and lower shell of the battery pack need to be fitted and pressed together to ensure that the sealing surfaces of the two are evenly fitted and the assembly gaps are consistent, thus avoiding assembly defects such as misalignment and warping during subsequent sealing and bolt fastening processes. The battery pack top cover pressing fixture, as a dedicated positioning and pressure application device on the assembly line, mainly relies on the pressing components to apply uniform pressure from above the top cover, stably limiting the displacement and deformation of the top cover during the assembly process.

[0033] In related technologies, most mainstream clamping fixtures in the industry at present are fixed, integrated structures. The overall installation position of the fixture cannot be flexibly moved and adjusted laterally or longitudinally, and it can only be used for battery pack top covers of a single specification size, making it difficult to be compatible with multiple battery pack products with different lengths, widths, and outlines. When changing production lines, the entire fixture must be replaced, which is time-consuming. At the same time, the clamping and pressure-applying components of the fixture are mostly fixed by bolts and welding, making disassembly and assembly cumbersome and not supporting quick disassembly and replacement. The overall fixture has poor versatility, which significantly increases production costs and time.

[0034] To solve the above technical problems, see [link to relevant documentation]. Figures 1 to 12 As shown, this application provides a battery pack top cover clamping fixture, including a frame 10, two sets of first clamping members 23, and two sets of second clamping members 33. The two sets of first clamping members 23 and the two sets of second clamping members 33 are all mounted on the frame 10. The frame 10 is movable along the vertical direction D1, thereby causing the two sets of first clamping members 23 and the two sets of second clamping members 33 to move along the vertical direction D1, thus enabling the two sets of first clamping members 23 and the two sets of second clamping members 33 to clamp the top cover of the battery pack.

[0035] Along the first direction D2, two sets of first clamping assemblies 20 are arranged at intervals. Each first clamping assembly 20 includes a connecting beam, a locking element, and a clamping element. For ease of distinction, the connecting beam of the first clamping assembly 20 is designated as a first connecting beam 21, the locking element as a first locking element 22, and the clamping element as a first clamping element 23. Along the first direction D2, the first connecting beam 21 is slidably connected to the frame 10. Thus, the two first connecting beams 21 move relative to each other along the first direction D2, adjusting the distance between them. It is understood that because the battery pack top cover needs to be clamped, the frame 10 is hollow in the middle, and the first clamping element 23 is located in the hollow portion and connected to the first connecting beam 21 to clamp the top cover. Therefore, the two ends of the first connecting beam 21 in the second direction D3 are slidably connected to the frame 10 along the first direction D2. The first direction D2 is perpendicular to the vertical direction D1, and the second direction D3 is perpendicular to both the first direction D2 and the vertical direction D1.

[0036] The first clamping member 23 is detachably connected to the first connecting beam 21, facilitating replacement of the first clamping member 23 to adapt to different types of battery pack top covers. The first locking member 22 is movably connected to the first connecting beam 21. When the first clamping member 23 is mounted on the first connecting beam 21, the first clamping member 23 can be quickly clamped or released by adjusting the first locking member 22. For example, the first locking member 22 can be an eccentric cam clamping mechanism, a quick-opening elbow clamp, a steel ball locking clamping structure, a spring elastic snap-on clamping structure, etc.

[0037] Along the vertical direction D1, two sets of first clamping components 20 and two sets of second clamping components 30 are staggered. The first clamping components 20 can be located above or below the second clamping components 30 to prevent interference between the two clamping components. Along the second direction D3, the two sets of second clamping components 30 are arranged alternately. Each second clamping component 30 includes a connecting beam, a locking element, and a clamping element. For ease of distinction, the connecting beam of the second clamping component 30 is designated as a second connecting beam 31, the locking element as a second locking element 32, and the clamping element as a second clamping element 33. Along the second direction D3, the second connecting beam 31 is slidably connected to the frame 10. Thus, the two second connecting beams 31 move relative to each other along the second direction D3, adjusting the distance between them. Understandably, since the battery pack top cover needs to be pressed down, the frame 10 is hollow in the middle, and the second pressing member 33 is located in the hollow part and connected to the second connecting beam 31 to press down the top cover. Therefore, the two ends of the second connecting beam 31 in the first direction D2 are slidably connected to the frame 10 in the second direction D3.

[0038] The second clamping member 33 is also detachably connected to the second connecting beam 31, facilitating replacement of the second clamping member 33 to adapt to different types of battery pack top covers. The second locking member 32 is movably connected to the second connecting beam 31. When the second clamping member 33 is mounted on the second connecting beam 31, the second clamping member 33 can be quickly clamped or released by adjusting the second locking member 32. For example, the second locking member 32 can be an eccentric cam clamping mechanism, a quick-opening elbow clamp, a steel ball locking clamping structure, a spring snap-on clamping structure, etc.

[0039] Before pressing the battery pack top cover, the two first connecting beams 21 are moved to their corresponding positions along the first direction D2, and the two second connecting beams 31 are moved to their corresponding positions along the second direction D3, according to the size of the battery pack to be pressed. A first pressing member 23 adapted to the current battery pack top cover is placed on the first connecting beam 21 and pressed and fixed by the first locking member 22. A second pressing member 33 adapted to the current battery pack top cover is placed on the second connecting beam 31 and pressed and fixed by the second locking member 32. The control frame 10 drives the first pressing member 23 and the second pressing member 33 to move downwards along the vertical direction D1, so that the first pressing member 23 and the second pressing member 33 press the battery pack top cover onto the battery pack, completing the pressing of the battery pack top cover.

[0040] In summary, the battery pack top cover clamping fixture of the present invention comprises two sets of first clamping components 20 and two sets of second clamping components 30 respectively arranged on a frame 10. The first connecting beam 21 of the first clamping component 20 is slidably connected to the frame 10 along a first direction D2, and the first clamping member 23 is detachably connected to the first connecting beam 21 via a first locking member 22. Simultaneously, the second connecting beam 31 of the second clamping component 30 is slidably connected to the frame 10 along a second direction D3, and the second clamping member 33 is detachably connected to the second connecting beam 31 via a second locking member 32. The movable first connecting beam 21 and the second connecting beam 31, and the detachable first clamping member 23 and the second clamping member 33, enable quick replacement, thereby achieving adaptability of the clamping fixture to battery pack top covers of different sizes and specifications, improving the versatility of the battery pack top cover clamping fixture, and increasing the production efficiency of battery packs.

[0041] Reference Figures 1 to 7 As shown, in some embodiments of the battery pack top cover clamping fixture of the present invention, multiple first locking members 22 are provided, and the multiple locking members are arranged sequentially at intervals along the length direction of the first connecting beam 21. For example, each first locking member 22 can be adapted to one first clamping member 23, or multiple first locking members 22 can be adapted to multiple first clamping members 23.

[0042] The first locking element 22 includes two support seats 221, a pressure plate 222, and two elbow clamps 223. The two support seats 221 are arranged alternately along the length of the first connecting beam 21 and are fixedly connected to the connecting beam. It can be understood that when multiple first locking elements 22 are provided, the support seats 221 of adjacent first locking elements 22 are arranged alternately and are relatively close to each other. A pressure plate 222 is provided for every two support seats 221, and the pressure plate 222 is located on the upper side of the two support seats 221.

[0043] Two elbow clamps 223 are disposed at both ends of the pressure plate 222. Each elbow clamp 223 includes a connecting rod 2231 and an adjusting component 2232, which are movably connected to the connecting rod 2231. One end of the connecting rod 2231 is connected to the support base 221, while the adjusting component 2232 is disposed on the upper side of the pressure plate 222. Furthermore, the adjusting component 2232 is movable relative to the connecting rod 2231 in the vertical direction D1 to abut or move away from the pressure plate 222. A first clamping member 23 is disposed between the first connecting beam 21 and the pressure plate 222. The adjusting component 2232 drives the pressure plate 222 to move downwards in the vertical direction D1, and the pressure plate 222, in conjunction with the first connecting beam 21, clamps the first clamping member 23.

[0044] Furthermore, the support base 221 is provided with a connecting groove 2211, and a first abutment portion 2212 is provided on the connecting groove 2211. The pressure plate 222 is provided with a first connecting through hole 2221, and the connecting rod 2231 passes through the first connecting through hole 2221 along the vertical direction D1. The connecting rod 2231 is slidably connected to the first connecting through hole 2221. A second abutment portion 22311 is provided at one end of the connecting rod 2231, and the second abutment portion 22311 is located within the connecting groove 2211. When the first pressing member 23 is pressed, the upper surface of the second abutment portion 22311 abuts against the lower surface of the first abutment portion 2212. When the first pressing member 23 is not pressed, the upper surface of the second abutment portion 22311 separates from the lower surface of the first abutment portion 2212.

[0045] Furthermore, the adjusting component 2232 includes a handle 22321, a first transmission rod 22322, a second transmission rod 22323, and a movable block 22324. One end of the handle 22321 is connected to one end of the first transmission rod 22322, and the other end of the first transmission rod 22322 is rotatably connected to the other end of the connecting rod 2231. One end of the second transmission rod 22323 is rotatably connected to the middle of the first transmission rod 22322, and the other end of the second transmission rod 22323 is rotatably connected to the movable block 22324. Along the vertical direction D1, the movable block 22324 is slidably connected to the connecting rod 2231 to move closer to or further away from the pressure plate 222.

[0046] When the first clamping member 23 is clamped, the handle 22321 is rotated, causing the first transmission rod 22322 to rotate relative to the connecting rod 2231, and the second transmission rod 22323 to rotate relative to the first transmission rod 22322, thereby causing the movable block 22324 to move downwards in the vertical direction D1 and abut against the pressure plate 222. The handle 22321 is then rotated further until the length direction of the second transmission rod 22323 is aligned with the line connecting the first transmission rod 22322 and the connecting rod 2231 from one end to the middle, thus locking the first locking member 22. At this time, the pressure plate 222 cooperates with the first connecting beam 21 to clamp and fix the first clamping member 23.

[0047] It is understandable that the structure and arrangement of the second locking member 32 are the same as those of the first locking member 22, and will not be described again in this embodiment.

[0048] Reference Figure 4 and Figure 8 As shown, the battery pack top cover clamping fixture of the present invention, in some embodiments, further includes multiple guide members 24, which are sequentially and spaced apart between two support seats 221 along the length direction of the first connecting beam 21. Each guide member 24 includes a guide rod 241 and a limiting end 242 in sequence. Along the vertical direction D1, one end of the guide rod 241 is connected to the first connecting beam 21, while the other end of the guide rod 241 is connected to the limiting end 242.

[0049] The first clamping member 23 is provided with multiple first guide grooves 231, and the bottom surface of each first guide groove 231 is provided with a second guide groove 232, with the first guide grooves 231 connecting to the second guide grooves 232. When the first clamping member 23 is inserted between the first connecting beam 21 and the pressure plate 222, a guide rod 241 is positioned within the second guide groove 232 and is slidably connected to the second guide groove 232 along the moving direction of the first connecting beam 21, ultimately abutting against the wall at the end of the second guide groove 232. Simultaneously, a limiting end 242 is positioned within the first guide groove 231 and is slidably connected to the first guide groove 231 along the moving direction of the first connecting beam 21, ultimately abutting against the wall at the end of the first guide groove 231. Furthermore, when the first clamping member 23 deviates vertically in the direction D1 during insertion, the bottom surface of the first guide groove 231 abuts against the lower surface of the limiting end 242, preventing the first clamping member 23 from deviating. Thus, the guide member 24 provides guidance and limitation for the first clamping member 23, improving the stability of the first clamping member 23 during clamping and insertion.

[0050] Preferably, there are two guide members 24, which not only provide stable positioning and guidance for the first clamping member 23, but also prevent the first clamping member 23 from having multiple first guide grooves 231 and multiple second guide grooves 232, thus affecting the structural strength.

[0051] It is understandable that the second clamping member 33 and the second connecting beam 31 are provided with the same corresponding structure, which will not be described in detail here.

[0052] Reference Figure 10 As shown, in some embodiments of the battery pack top cover clamping fixture of the present invention, the second clamping member 33 is provided with a clearance groove 331. In this case, a single second clamping member 33 corresponds to multiple second locking members 32, or the length of a single second clamping member 33 is relatively long, exceeding the length of the pressure plate 222. Along the moving direction of the second connecting beam 31, the clearance groove 331 is slidably connected to the support seat 221 of the second locking member 32 to provide clearance for the support seat 221.

[0053] Reference Figure 1 , Figure 2 , Figure 11 and Figure 12 As shown, in some embodiments of the battery pack top cover clamping fixture of the present invention, a guide rail 40 is provided on the frame 10, a connecting seat 60 is provided at one end of the connecting beam, and a slider 50 is provided on the connecting seat 60. The slider 50 is slidably connected to the guide rail 40 along the moving direction of the first connecting beam 21. Thus, the guide rail 40 and the slider 50 provide stable sliding guidance for the sliding of the first connecting beam 21. Furthermore, if two guide rails 40 are provided on the frame 10, then the connecting seat 60 and the slider 50 are respectively provided at both ends of the first connecting beam 21, and the slider 50 is slidably connected to the guide rail 40, thereby improving the stability of the sliding guidance.

[0054] Furthermore, the battery pack top cover clamping fixture also includes a fixing member 70. A first threaded through hole 61 is provided on the connecting seat 60. The fixing member 70 passes through the first threaded through hole 61 and is threadedly connected to it. Correspondingly, multiple fixing holes 11 are provided on the frame 10, arranged sequentially at intervals along the moving direction of the first connecting beam 21. A fixing end 71 is provided at the end of the fixing member 70 near the frame 10. After the first connecting beam 21 is moved to the corresponding position, the fixing member 70 is screwed to move the fixing end 71 downwards in the vertical direction D1 to insert into the fixing hole 11, completing the positioning and fixing. After the top cover is clamped, the fixing member 70 is screwed to move the fixing end 71 upwards in the vertical direction D1 to pull out the fixing hole 11.

[0055] Furthermore, a laser scale 80 is provided on one side of the fixing hole 11, and the position of the fixing hole 11 corresponds one-to-one with the scale of the laser scale 80 along the arrangement direction of the multiple fixing holes 11. In this way, a more accurate reference benchmark can be provided for the position of the first connecting beam 21, improving the clamping accuracy.

[0056] Understandably, the sliding connection and positioning and fixing method between the second connecting beam 31 and the frame 10 is the same as that of the first connecting beam 21, and will not be repeated here.

[0057] Reference Figures 8 to 10 As shown, in some embodiments of the battery pack top cover clamping fixture of the present invention, the first clamping member 23 is provided with a plurality of second connecting through holes 233, which are arranged at intervals along the length direction of the first connecting beam 21. It can be understood that the second connecting through holes 233 can be evenly spaced to provide a uniform clamping force to the top cover. When the top cover has an irregular shape, the arrangement of the second connecting through holes 233 needs to be set according to actual requirements.

[0058] The battery pack top cover clamping fixture also includes multiple clamping blocks 90. Each clamping block 90 has a connecting portion 91, and the connecting portion 91 has a second threaded through hole 2331. The connecting portion 91 is located within the second connecting through hole 2331, and a third threaded through hole 92 corresponding to the second threaded through hole 2331 is provided on the side wall of the second connecting through hole 2331. When the connecting portion 91 is located within the second connecting through hole 2331, the third threaded through hole 92 communicates with the second threaded through hole 2331 and is connected by bolts. Thus, when clamping the top cover, one end of the clamping block 90 abuts against the top cover, thereby achieving the clamping of the top cover. The arrangement of multiple clamping blocks 90 ensures stability during clamping and prevents obstruction of the connection between the top cover and the battery pack.

[0059] Understandably, the clamping structure of the second clamping member 33 is the same as that of the first clamping member 23, and will not be described again here.

[0060] Reference Figures 1 to 3As shown, the battery pack top cover clamping fixture of the present invention, in some embodiments, includes a frame 10 comprising two first connecting plates 12, two second connecting plates 13, four first connecting members 14, and four second connecting members 15. The two first connecting plates 12 are arranged at intervals along a first direction D2, and the two second connecting plates 13 are arranged at intervals along a second direction D3. Along the second direction D3, the two ends of each first connecting plate 12 are connected to one end of each of the two second connecting plates 13, forming a frame 10 that is lightweight and has a simple structure. The first connecting members 14 are located on the upper side of the two connected ends and are connected to the ends of the first connecting plates 12 and the second connecting plates 13, respectively, thereby enhancing the connection strength. The second connecting members 15 are located on the lower side of the two connected ends and are connected to the ends of the first connecting plates 12 and the second connecting plates 13, respectively, to further enhance the connection strength.

[0061] Working principle: Based on the dimensions of the battery pack top cover, the two first connecting beams 21 are controlled to move along the first direction D2, while the second connecting beam 31 is controlled to move along the second direction D3. After moving to the corresponding positions, the first connecting beams 21 and 31 are positioned and fixed by the fixing members 70 on the connecting seat 60. The first clamping member 23 is inserted between the pressure plate 222 and the first connecting beam 21, and the handle 22321 is turned to control the movable block 22324 to abut against the pressure plate 222 and press the first clamping member 23. The second clamping member 33 is connected in the same way. The control frame 10 moves closer to the top cover along the vertical direction D1, and the pressing blocks 90 on the first clamping member 23 and the second clamping member 33 abut against the top cover to press the top cover onto the battery pack.

[0062] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0063] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0064] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
