Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a battery assembly tool. Background Art

[0002] In the process of grouping soft-pack batteries into modules in the new energy lithium battery industry, different products have different combination methods. After grouping, laser welding is required to achieve a stable connection between the pole tab bracket and the pole tab.

[0003] At present, most products still use robots for horizontal laser welding. In some production lines with low automation levels, horizontal laser welding cannot be implemented, so vertical laser welding of the modules is required. However, since the battery cells are placed horizontally during the stacking process and the battery cells are limited to a low degree before welding after the stacking is completed, once the horizontal state is changed to the vertical state, it is easy for the battery cells to move and cause position deviation, which ultimately affects the welding quality and causes the battery to fail.

[0004] Therefore, there is an urgent need to provide a battery assembly tool to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0010] Wherein, the limiting frame includes a bottom plate and supporting legs, the bottom plate is rectangular, the supporting legs are located at the four corners of the bottom plate and protrude from the bottom plate in the vertical direction.

[0011] Specifically, a positioning protrusion is formed on one side of the leg facing the fixing frame, and a matching recess is formed on the fixing frame at a position corresponding to the positioning protrusion, and the positioning protrusion can be plugged into the matching recess.

[0012] Specifically, a first clamping piece is provided on the supporting leg, and a first connecting piece is provided on the fixing frame at a position corresponding to the first clamping piece.

[0014] Furthermore, a third clamping piece is provided on the side of the support plate away from the limit frame, and a third connecting piece is provided on the fixing frame at a position corresponding to the third clamping piece. The third connecting piece is connected or separated from the third clamping piece so that the support plate can be connected or separated from the fixing frame.

[0016] Compared with the prior art, the battery assembly tool provided by the utility model has the following advantages:

[0017] The battery assembly tool provided by the utility model is used for assembling and forming a battery module, and includes a limiting mechanism and a fixing mechanism; the limiting mechanism includes a limiting frame and a supporting plate, the supporting plate is located at one side of the limiting frame, and the supporting plate can be located at the same horizontal plane as the limiting frame or perpendicular to the plane where the limiting frame is located; the fixing mechanism includes a fixing frame and a clamping assembly, the fixing frame is detachably connected to the limiting frame, one side of the fixing frame and the first side of the limiting frame are surrounded to form a positioning space for positioning the pole ear bracket in the battery module, and a avoiding portion is formed on the side of the fixing frame facing the supporting plate, the clamping assembly is detachably connected to the fixing frame, and the clamping assembly is arranged relative to the limiting frame, and is used to clamp the battery cells of the battery module accommodated between the fixing frame and the limiting frame.

[0018] From this analysis, it can be seen that through the detachable connection between the fixing frame and the limit frame, an installation space for carrying the battery cells can be enclosed and formed, and since a support plate is connected to one side of the limit frame in the present application, and the support plate can also be located on the same horizontal plane as the limit frame or perpendicular to the plane where the limit frame is located, accordingly, an avoidance portion is formed on the side of the fixing frame facing the support plate. Therefore, when the battery cells are stacked, the support plate is first adjusted to a state where it is located on the same horizontal plane as the limit frame, so that the battery cells can enter the formed installation space from the avoidance portion.

[0019] Since a positioning space can be formed between the side of the fixing frame relative to the avoidance portion and the first side of the limiting frame in the present application, the tab bracket in the battery module can be positioned through the positioning space. Furthermore, by providing a clamping assembly on the fixing frame and making the clamping assembly relative to the limiting frame, the battery cells stacked in the installation space can be limited and clamped.

[0020] When using the battery assembly tool provided by the present application, the support plate is first unfolded and maintained in a state of being on the same horizontal plane as the limit frame, and then the tab bracket in the battery module is installed on the first side of the limit frame, and the fixing frame and the limit frame are assembled at the same time, so as to achieve the limitation and support of the tab bracket. After the tab bracket is fixed, the battery cells are stacked in sequence from the avoidance part into the installation space, and the tabs of the battery cells are passed through the tab bracket and connected to the tab bracket.

[0021] When the battery cells are stacked, the support plate is adjusted to a state perpendicular to the plane where the limit frame is located, so that the ends of the battery cells can be aligned and limited by the support plate, thereby ensuring the stability of the battery cells in the installation space. Finally, the clamping assembly is connected to the fixing frame. Since the clamping assembly and the limit frame are arranged relative to each other, the battery cells can be stably limited in the installation space through the fixing frame, the limit frame, the support plate and the clamping assembly to avoid the battery cells from moving in all directions. When the battery module needs to be welded longitudinally, the overall vertical tooling can drive all the battery cells in the installation space to remain in the vertical direction, and under the limiting effect of the clamping assembly, the fixing frame, the limit frame and the support plate, the problem of movement can be avoided, and the vertical welding operation can be stably realized, solving the problem of limited welding methods.

[0022] Moreover, under the action of the support plate, the ends of the misaligned battery cells can be aligned, and under the joint cooperation and limitation of structures such as the fixing frame and the clamping assembly, the stable transfer and transportation of the battery module can be achieved.

[0039] like Figure 1-Figure 4As shown, the utility model provides a battery assembly tool, which is used for assembling and forming a battery module, including a limiting mechanism and a fixing mechanism; the limiting mechanism includes a limiting frame 1 and a support plate 2, the support plate 2 is located on one side of the limiting frame 1, and the support plate 2 can be located in the same horizontal plane as the limiting frame 1 or perpendicular to the plane where the limiting frame 1 is located; the fixing mechanism includes a fixing frame 3 and a clamping assembly, the fixing frame 3 is detachably connected to the limiting frame 1, one side of the fixing frame 3 and the first side of the limiting frame 1 are surrounded to form a positioning space, which is used to position the pole ear bracket 9 in the battery module, and a avoiding portion 301 is formed on the side of the fixing frame 3 facing the support plate 2, the clamping assembly is detachably connected to the fixing frame 3, and the clamping assembly is arranged relative to the limiting frame 1, which is used to clamp the battery cells of the battery module accommodated between the fixing frame 3 and the limiting frame 1.

[0040] Compared with the prior art, the battery assembly tool provided by the utility model has the following advantages:

[0041] The battery assembly tool provided by the utility model is detachably connected through the fixing frame 3 and the limit frame 1, and can be surrounded to form an installation space for carrying battery cells. Since the limit frame 1 in the present application is connected to a support plate 2 on one side, and the support plate 2 can also be located on the same horizontal plane as the limit frame 1 or perpendicular to the plane where the limit frame 1 is located, correspondingly, an avoidance portion 301 is formed on the side of the fixing frame 3 facing the support plate 2. Therefore, when the battery cells are stacked, the support plate 2 is first adjusted to a state where it is located on the same horizontal plane as the limit frame 1, so that the battery cells can enter the formed installation space from the avoidance portion 301.

[0042] Since a positioning space can be formed between one side of the fixing frame 3 relative to the avoidance portion 301 and the first side of the limiting frame 1 in the present application, the tab bracket 9 in the battery module can be positioned through the positioning space. Furthermore, by providing a clamping assembly on the fixing frame 3 and making the clamping assembly relative to the limiting frame 1, the battery cells stacked in the installation space can be limited and clamped.

[0043] When using the battery assembly tool provided by the present application, the support plate 2 is first unfolded and maintained in a state of being on the same horizontal plane as the limiting frame 1, and then the tab bracket 9 in the battery module is installed on the first side of the limiting frame 1, and the fixing frame 3 and the limiting frame 1 are assembled at the same time, so as to achieve the limitation and support of the tab bracket 9. After the tab bracket 9 is fixed, the battery cells are stacked in sequence from the avoidance portion 301 into the installation space, and the tabs of the battery cells are passed through the tab bracket 9 and connected to the tab bracket 9.

[0044] After the battery cells are stacked, the support plate 2 is adjusted to a state perpendicular to the plane where the limit frame 1 is located, so that the ends of the battery cells can be aligned and limited by the support plate 2, thereby ensuring the stability of the battery cells in the installation space. Finally, the clamping assembly is connected to the fixing frame 3. Since the clamping assembly and the limit frame 1 are arranged relative to each other, the battery cells can be stably limited in the installation space by the fixing frame 3, the limit frame 1, the support plate 2 and the clamping assembly to avoid the battery cells from moving in all directions. When the battery module needs to be welded longitudinally, the overall tooling vertical mode can drive all the battery cells in the installation space to remain in the vertical direction, and under the limiting effect of the clamping assembly and the fixing frame 3, the limit frame 1 and the support plate 2, the problem of movement can be avoided, and the vertical welding operation can be stably realized, solving the problem of limited welding methods.

[0045] Moreover, under the action of the support plate 2, the ends of the misaligned battery cells can be aligned, and under the joint cooperation and limitation of the fixing frame 3 and the clamping assembly and other structures, the stable transfer and transportation of the battery module can be achieved.

[0046] It can be understood that when the support plate 2 is perpendicular to the limiting frame 1, the end of the support plate 2 away from the limiting frame 1 is blocked at the position of the avoidance portion 301 and connected to the fixing frame 3, so as to form the following Figure 1 The rectangular frame structure shown is used to achieve stable positioning of the battery cells.

[0047] The detachable connection between the support plate 2 and the fixing frame 3 can be achieved by fasteners such as bolts, that is, screw holes are correspondingly formed on the support plate 2 and the fixing frame 3, and bolts are driven into the screw holes to achieve the detachable connection between the support plate 2 and the fixing frame 3. The connection between the fixing frame 3 and the limiting frame 1 can be achieved by bolts in combination with connecting plates, that is, the two ends of the connecting plate are respectively fitted with the fixing frame 3 and the limiting frame 1, and correspondingly, screw holes are opened at corresponding positions, so that the two ends of the connecting plate can be connected to the fixing frame 3 and the limiting frame 1 respectively by bolts, thereby achieving the detachable connection between the fixing frame 3 and the limiting frame 1.

[0048] Alternatively, if Figure 1 As shown, a first side of the limiting frame 1 in the present application and a surface facing the fixing frame 3 are formed with a plurality of first positioning portions 1011, and a first matching portion is formed at a position of the pole lug bracket 9 corresponding to the first positioning portion 1011, and the first positioning portion 1011 is plugged into the first matching portion to position the pole lug bracket 9.

[0049] The multiple first positioning portions 1011 in the present application are cylindrical protrusions, and the pole lug bracket 9 can be positioned by the first positioning portions 1011 arranged at intervals on the first side, thereby ensuring that the pole lug bracket 9 can be connected to the limit frame 1 in the vertical direction before the fixing frame 3 is installed.

[0050] Furthermore, the fixing frame 3 in the present application is parallel to the crossbeam of the first side of the limiting frame 1, and a plurality of second positioning portions are formed on one side of the crossbeam facing the limiting frame 1, and a second matching portion is formed at the position of the pole ear bracket 9 corresponding to the second positioning portion, and the second positioning portion is plugged into the second matching portion to position the pole ear bracket 9.

[0051] The number of the first positioning portion 1011 and the second positioning portion in the present application can be consistent or different. Accordingly, the setting intervals and relative positions of the first positioning portion 1011 and the second positioning portion can also be the same or different. It is only necessary to ensure that the two sides of the pole lug bracket 9 correspond to the first positioning portion 1011 and the second positioning portion. By plugging the first positioning portion 1011 and the second positioning portion into the first matching portion and the second matching portion, the stability of the pole lug bracket 9 can be ensured and the accuracy of installation can be improved.

[0052] Alternatively, if Figure 2 As shown, a rotating member 203 is provided between the limit frame 1 and the support plate 2 in the present application, one end of the rotating member 203 is connected to one side of the support plate 2, and the other end is connected to one side of the limit frame 1, so that the support plate 2 can rotate relative to the limit frame 1.

[0053] The rotating member 203 in the present application can adopt a structure such as a hinge, a folding axis or a hinge that can realize the rotation of the support plate 2 relative to the limit frame 1 and maintain it in a horizontal or vertical state. By rotating the support plate 2 relative to the limit frame 1, the above-mentioned installation space can be quickly opened or closed, thereby ensuring the installation accuracy of the battery cell.

[0054] Alternatively, if Figure 1-Figure 4 As shown, the limiting frame 1 in the present application includes a bottom plate 101 and legs 102 . The bottom plate 101 is rectangular. The legs 102 are located at the four corners of the bottom plate 101 and protrude from the bottom plate 101 in the vertical direction.

[0055] Since the pole lug bracket 9 needs to be positioned first when assembling the battery module, the legs 102 arranged on the base plate 101 and protruding from the base plate 101 in the vertical direction can provide a certain degree of support and guidance for the pole lug bracket 9. After the first matching portion on the pole lug bracket 9 is plugged into the first positioning portion 1011, the stability of the pole lug bracket 9 is ensured, and the problem of the pole lug bracket 9 tipping over when the fixing frame 3 is installed is avoided.

[0056] It can be understood that the first side of the above-mentioned limiting frame 1 refers to the side of the bottom plate 101 away from the support plate 2. By forming the first positioning portion 1011 on the first side, it is convenient to position the tab bracket 9 and install the subsequent battery cells.

[0057] Alternatively, if Figure 2 As shown, the leg 102 in the present application is formed with a positioning protrusion 1021 on one side facing the fixing frame 3 , and the fixing frame 3 is formed with a matching recess at a position corresponding to the positioning protrusion 1021 , and the positioning protrusion 1021 can be plugged into the matching recess.

[0058] By means of the positioning protrusion 1021 formed on the support leg 102 and the matching recess formed on the fixing frame 3 at the position corresponding to the positioning protrusion 1021, the positioning between the fixing frame 3 and the limiting frame 1 can be achieved quickly and accurately, thereby avoiding the problem of inadequate connection between the fixing frame 3 and the limiting frame 1, resulting in an irregular installation space and causing the battery cell to shift and move in the installation space.

[0059] Alternatively, if Figure 1-Figure 4 As shown, the support leg 102 in the present application is provided with a first clamping member 1022, and the fixing frame 3 is provided with a first connecting member 302 at a position corresponding to the first clamping member 1022. The first connecting member 302 can be clamped or separated from the first clamping member 1022 so that the fixing frame 3 and the limiting frame 1 can be detachably connected.

[0060] By setting a first clamping member 1022 on the support leg 102 and setting a first connecting member 302 at a position of the fixing frame 3 corresponding to the first clamping member 1022, the fixing frame 3 and the limiting frame 1 can be quickly connected and disassembled by clamping or separating the first connecting member 302 and the first clamping member 1022.

[0061] Accordingly, if Figure 1-Figure 4 As shown, the clamping assembly in the present application includes a pressure strip 4 and a second connecting member 5. A second clamping member 303 is provided at a position of the fixing frame 3 corresponding to the pressure strip 4. The second connecting member 5 is clamped or separated from the second clamping member 303 to make the pressure strip 4 and the fixing frame 3 detachably connected.

[0062] The fast connection and disassembly between the pressure strip 4 and the fixing frame 3 can also be achieved by the clamping and separation of the second connecting member 5 and the second clamping member 303 .

[0063] It can be understood that both ends of the pressure strip 4 in the present application are provided with a second connecting member 5, and accordingly, the position of the fixing frame 3 corresponding to the second connecting member 5 is also provided with a second clamping member 303, so that the pressure strip 4 can be stably connected to the fixing frame 3 to ensure the limiting effect on the battery cell in the installation space.

[0064] Accordingly, if Figure 1-Figure 4 As shown, the support plate 2 in the present application is provided with a third clip 201 on the side away from the limiting frame 1, and a third connecting member 304 is provided at a position corresponding to the third clip 201 on the fixing frame 3. The third connecting member 304 is connected or separated from the third clip 201 so that the support plate 2 can be connected or separated from the fixing frame 3.

[0065] Since the support plate 2 in the present application needs to be able to rotate relative to the limit frame 1, and when the support plate 2 is needed to limit the battery cell, the support plate 2 is in a vertical state relative to the limit frame 1. Therefore, by setting a third clamping member 201 on the support plate 2, and setting a third connecting member 304 at a position corresponding to the third clamping member 201 on the fixing frame 3, the support plate 2 and the fixing frame 3 can be quickly connected and disassembled by clamping or separating the third connecting member 304 and the third clamping member 201.

[0066] Alternatively, if Figure 5 As shown, the first connecting member 302, the second connecting member 5 and the third connecting member 304 in the present application all include a positioning seat 6, a retaining ring 8 and a driving arm 7, and the first clamping member 1022, the second clamping member 303 and the third clamping member 201 are all formed with a clamping groove; the driving arm 7 is rotationally connected to the positioning seat 6, and the retaining ring 8 is rotationally connected to the driving arm 7. The rotation of the driving arm 7 relative to the positioning seat 6 can drive the retaining ring 8 to move in the direction close to or away from the clamping groove, so that the retaining ring 8 is clamped or separated from the clamping groove.

[0067] Taking the first connecting member 302 and the first clamping member 1022 as an example, when it is necessary to connect the fixing frame 3 with the limiting frame 1, the driving arm 7 is first rotated to a direction perpendicular to the fixing frame 3. Since one end of the clamping ring 8 is connected to the driving arm 7, the clamping ring 8 can be driven to move in a direction close to the first clamping member 1022.

[0068] After the other end of the snap ring 8 approaches the first clamping member 1022, rotate the snap ring 8 so that the other end of the snap ring 8 enters the clamping groove, and rotate the driving arm 7 so that the axis of the driving arm 7 is parallel to the axis of the support leg 102, even if the driving arm 7 is in a state of extending in the vertical direction, thereby driving the snap ring 8 to move away from the first clamping member 1022, and then tightening the clamping degree between the snap ring 8 and the first clamping member 1022 to ensure a stable connection between the fixing frame 3 and the limit frame 1.

[0069] The operation modes between the second connecting member 5 and the second clamping member 303 and between the third connecting member 304 and the third clamping member 201 are the same, and will not be described again.

[0070] Preferably, if Figure 1 As shown, the support plate 2 in the present application is provided with a first handle 202, and the fixing frame 3 is provided with a second handle 305 at a position relative to the first handle 202. The first handle 202 and the second handle 305 respectively provided on the support plate 2 and the fixing frame 3 can facilitate operators to lift or use lifting tools to lift the entire battery assembly tooling, thereby facilitating the transfer and transportation of the tooling.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
