Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and in particular to a blade battery module welding, pressing, positioning and flipping tooling. Background Art

[0002] The blade battery module is a new battery design characterized by a long, thin battery cell that resembles a blade, hence its name. This design allows the battery cells to be placed directly within the battery pack, eliminating the need for a traditional module structure, thereby improving space utilization and energy density.

[0003] The welding process for blade battery modules primarily utilizes laser welding technology. Laser welding boasts advantages such as high energy density, high precision, and high flexibility. Laser welding equipment is used to weld the connection points of battery cells. Laser welding boasts high speed and a small heat-affected zone, improving weld quality and reducing material deformation, making it ideally suited for the precision requirements of lithium battery manufacturing.

[0004] At present, when welding blade battery modules, a galvanometer is used as the welding light source. To ensure that the galvanometer can weld at different positions of the module, the galvanometer is installed on a three-axis slide. The galvanometer can be moved to different positions of the battery module under the action of the three-axis slide. After moving to the specified position, the galvanometer emits a light source and emits a laser towards the module directly below to complete the welding operation.

[0005] After reviewing the existing technology, it was found that this technology still has some shortcomings during use. Since the light source emitted by the galvanometer is in the vertical direction, even under the action of the three-axis slide, it can only support welding on one side of the module. When welding, the module is fixed on the welding table. If welding is done on different sides of the module, the galvanometer cannot adjust its posture under the drive of the three axes. After the position of the module is fixed on the welding table, it is difficult to make welding adjustments to different sides of the module, and it cannot adapt to the welding requirements of the poles on both sides of the blade battery. If it is necessary to weld both sides of the battery module, it is necessary to add an additional three-axis slide and galvanometer structure, or after the module is fixed on the welding table, it is necessary to adjust the position of the module on the welding table so that the other required welding surface faces the galvanometer, which increases the trouble of adjusting the module posture. At the same time, it is also impossible to adjust the posture of the battery module to meet the welding requirements of different sides of the battery module.

[0006] Therefore, the present application aims to improve the switching efficiency of different welding surfaces of the blade battery module, while also meeting the welding requirements of different surfaces of the battery module. Summary of the Invention

[0007] The main purpose of the present invention is to provide a method for improving the switching efficiency of different welding surfaces of the blade battery module, while also meeting the welding requirements of different surfaces of the battery module.

[0008] In order to achieve the above-mentioned purpose, the present invention proposes a blade battery module welding, pressing, positioning and flipping tool comprising:

[0009] A tray having a supporting surface for placing the battery modules;

[0010] an abutting end, provided at one end of the tray bearing surface;

[0011] A pressing member is provided at an end of the tray bearing surface away from the abutting end and pushes the battery module toward the abutting end;

[0012] Side pressure plates, provided between the pressing member and the abutting end and on both sides of the tray bearing surface, for pressing and fixing a plurality of busbars in the battery module; and

[0013] The tray is rotatably connected to the support member at both ends along the length direction.

[0014] In the above scheme, a battery module is placed on the supporting surface. The battery module is composed of a plurality of batteries, and the batteries are placed in sequence from one side of the abutting end. Then, the pressing member squeezes the batteries away from the abutting end to compress the batteries and arrange the batteries tightly. Bus bars can be installed on both sides of the plurality of batteries to form the entire battery module. The side pressure plates squeeze both sides of the battery module so that the side pressure plates, the pressing members and the abutting end press the battery module tightly and fix it on the tray. The two ends of the tray rotate on the support members to adjust the rotation direction of the battery module, which is convenient for subsequent posture adjustment of the battery module. After welding on one side of the battery module is completed, it can be switched to the other side for corresponding welding.

[0015] Furthermore, the clamping member includes a clamping plate fixedly connected to the tray, a main shaft threadedly connected to the clamping plate toward the abutting end, and a push plate rotatably connected to one end of the main shaft near the abutting end. The push plate is fixed with at least one guide shaft in the direction of the clamping plate, and the guide shaft is slidably connected to the clamping plate. One end of the main shaft is a polygonal structure that can be used with a square ratchet wrench. The rotation of the square ratchet wrench can drive the main shaft to rotate, and the rotation of the main shaft will drive the push plate to move relative to the clamping plate toward the abutting end. An insulating plate is installed on the side of the push plate facing the battery module. The push plate drives the insulating plate to squeeze the battery module, so that the battery modules are tightly arranged, which can effectively improve the accuracy of manual verification.

[0016] Furthermore, the side pressure plate includes at least one pair of main pressure plates, the pressing members and the abutting ends are both mounted with fixing seats on both sides of the side pressure plates, and the two ends of the main pressure plate are detachably connected to the fixing seats. The main pressure plate is used to press the busbar against the pole of the battery module. A manual clamp can be installed at the fixing seat to fix the two ends of the main pressure plate between the pressing vertical plate and the abutting end. Alternatively, a slot can be provided at the top of the fixing seat so that the two ends of the main pressure plate are embedded in the slot. The busbar can be squeezed against the pole through the main pressure plate, which can greatly improve the convenience of the main pressure plate pressing the battery module.

[0017] Furthermore, the side pressure plate further includes a secondary pressure plate located on the same side as the main pressure plate, capable of compressing or releasing the battery modules on both sides. The secondary pressure plate can be moved using a telescopic cylinder, such as a pneumatic or electric cylinder, mounted on a tray. The telescopic end of the cylinder is extended, pressing the secondary pressure plate against both sides of the battery module. When the telescopic end of the cylinder is released, the secondary pressure plate and both sides of the battery module are released, allowing for subsequent removal and replacement.

[0018] Furthermore, the tray includes a support plate for supporting the battery module, a long side upright plate located on the side of the support plate away from its supporting surface, and an adapter plate fixedly connected to the side of the secondary pressure plate away from the side on which it presses the battery module, wherein the adapter plate is slidably connected to the support plate. A slot for placing the battery module can be provided on the supporting surface of the support plate, and a plurality of lightweight holes are also provided. The long side upright plates can be provided on both sides of the side pressure plate or around the support plate. When the secondary pressure plate slides along the support plate, the stability of the secondary pressure plate clamping the battery module can be improved.

[0019] Furthermore, the adapter plate is slidably connected to the long side upright plate, and an adjustment device is provided on one side of the long side upright plate to drive the secondary pressure plate to compress or release the battery module. The adjustment device can be in the form of a manual clamp. For example, the adapter plate drives the secondary pressure plate to move toward the battery module until the secondary pressure plate presses against the battery module. At this time, the manual clamp can clamp the adapter plate to achieve locking.

[0020] Furthermore, the adapter plate passes through the long side vertical plate, and is fixedly connected to a connecting plate at one end thereof away from the auxiliary pressure plate. The connecting plate is fixedly connected to a limiting shaft facing the long side vertical plate on the corresponding side, and the limiting shaft is slidably connected to the long side vertical plate. An adjustment device is provided at the end of the limiting shaft passing through the long side vertical plate. The number of adapter plates can be multiple, and the ends of the multiple adapter plates away from the auxiliary pressure plate are fixedly connected to the same connecting plate. The number of limiting shafts can be multiple, and the limiting shafts drive the adapter plate and the connecting plate to move relative to the long side vertical plate. The adjustment device is installed on the long side vertical plate, and the adjustment device is preferably in the form of a manual clamp. In this case, the manual clamp is provided at the end of the long side vertical plate close to the limiting shaft. When the manual clamp is rotated, the limiting shaft, the connecting plate, and the adapter plate drive the auxiliary pressure plate to be squeezed toward the battery module, thereby achieving compression and fixation of the battery module.

[0021] Furthermore, a pressing member is provided on the opposite side of the bearing surface from the support plate, and both ends of the pressing member are detachably connected to the pressing member and the abutting end. The two ends of the pressing plate are fixed to the pressing member and the abutting end by snapping, plugging, snapping, or clamping, preferably using a clamp, so that disassembly can be completed by simply moving the clamp, thereby improving the convenience of disassembly.

[0022] Furthermore, a torque transmission member is provided at one end of the tray's rotation. The torque transmission member includes a reducer fixed to the support member, a connecting block fixed to the output end of the reducer, and a fixed connection block to one end of the tray. The tray is also equipped with a locking member for adjusting the tray's tilting angle. The input shaft is the input end of the reducer, and a handwheel can be installed on the input shaft to facilitate user operation. When the handwheel is turned, the reducer drives the connecting block to rotate. The connecting block is fixed to one end of the support plate, thereby driving the tray and battery module to rotate, making it easy to change the battery module's posture and facilitating welding on different surfaces.

[0023] Furthermore, the locking member includes a fixed plate installed on one side of the reducer, a plug shaft slidably arranged on the fixed plate, and a chuck fixed on one side of the connecting block. The chuck is provided with a plurality of clamping holes at one end of the plug shaft, and the clamping holes are used to clamp and fix the end of the plug shaft. Among them, a limit seat is fixed on the fixed plate, and a linear bearing is installed on the limit seat. The plug shaft is slidably connected to the limit seat through the linear bearing. A handle for moving the plug shaft is also provided on the limit seat. By moving the handle, the plug shaft can be driven away from the clamping hole. At this time, unlocking is achieved, and the tray and battery module can be driven to rotate by the reducer and the connecting block. When the rotation reaches the required position, the plug shaft is automatically inserted into the subsequent clamping hole by means of a spring latch, that is, the rotation of the tray is locked to ensure that the posture of the battery module is fixed.

[0024] The above technical solution has the following advantages:

[0025] The present invention adopts the abutting end to abut against one side of the battery module, and the pressing part to squeeze the battery module so that the battery module is squeezed toward the abutting end, and the battery module is pressed and limited along the length direction of the tray. It can also be compatible with blade battery modules of different lengths. Secondly, the side pressure plate presses and fixes the other two sides of the battery module on the bearing surface, and presses the two sides of the busbar on the battery pole, and reserves space for laser welding. After the welding of one side of the battery module is completed, it is only necessary to adjust the welding position of the battery module through the tray, and the different welding surfaces of the battery module can be directed towards the welding equipment, which greatly improves the adjustment posture of the welding surface of the battery module, improves the switching efficiency of different welding surfaces of the blade battery module, and also meets the welding of different surfaces of the battery module.

[0026] The side pressure plate of the present invention adopts the auxiliary pressure plate to fix the busbar on the battery pole to achieve the effect of pre-positioning. Secondly, the two ends of the main pressure plate can be manually fixed between the clamping piece and the abutting end. The entire installation is convenient. At the same time, the two sides of the busbar are clamped, which improves the tightness of the contact between the busbar and the battery and improves the welding efficiency.

[0027] The present invention places the adapter plate and the connecting plate in close contact with the support plate, reducing the complexity of its structure. At the same time, when the tray and the battery module rotate, the interference of the connecting plate and the adapter plate on the rotation of the tray can be avoided. The long side vertical plate adopts a clamping method, which can more conveniently control the auxiliary pressure plate to tighten or loosen the bus at the battery module, thereby simplifying the operation steps.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation of the present invention.

[0039] like Figure 1 and Figure 3 As shown, a blade battery module welding, pressing, positioning and flipping tool includes a tray 8, an abutment end 7, a pressing member 4, a side pressure plate and a support member 1. The tray 8 is provided with a bearing surface for placing the battery module 9; the abutment end 7 is provided at one end of the bearing surface of the tray 8; the pressing member 4 is provided at the end of the bearing surface of the tray 8 away from the abutment end 7, and pushes the battery module 9 toward the abutment end 7; the side pressure plates are provided between the pressing member 4 and the abutment end 7, and are located on both sides of the bearing surface of the tray 8, which press and fix several bus bars 91 in the battery module 9; the two ends of the tray 8 along the length direction are rotatably connected to the support member 1. Among them, a battery module 9 is placed on the bearing surface. The battery module 9 is composed of several batteries, so that the batteries are placed in sequence from one side of the abutment end 7. Secondly, the clamping member 4 squeezes the batteries away from the abutment end 7 to compress the batteries and arrange the batteries tightly. The busbars 91 can be installed on both sides of the several batteries to form the entire battery module 9. The side pressure plates squeeze the two sides of the battery module 9 so that the side pressure plates, the clamping members 4 and the abutment end 7 press the battery module 9 to fix it on the tray 8; the two ends of the tray 8 rotate on the support member 1 to adjust the rotation direction of the battery module 9, which is convenient for subsequent posture adjustment of the battery module 9, and after the welding on one side of the battery module 9 is completed, it can be switched to the other side for corresponding welding.

[0040] like Figure 1 and Figure 2 As shown, specifically, the support member 1 includes at least two pillars 12, which are distributed at both ends of the tray 8. The top ends of the pillars 12 rotate with the two ends of the tray 8 respectively, wherein the end of the tray 8 close to the abutment end 7 is also fixedly installed with a connecting seat 87, and the connecting seat 87 and the corresponding pillar 12 are also provided with a support seat 88. The support seat 88 and the connecting seat 87 are preferably driven by a bearing to reduce friction. The bottom ends of the pillars 12 are preferably installed with the same bottom plate 11. The height of the pillars 12 is sufficient for the tray 8 and the battery module 9 to rotate, thereby adjusting the posture of the battery module 9; the pillars 12 can also be replaced by blocks to increase the support force for the tray 8 and the battery module 9. The clamping member 4 can be a telescopic cylinder, such as an oil cylinder, an air cylinder or an electric cylinder. Its telescopic end can push the battery module 9 toward the abutment end 7, so that multiple batteries are arranged closely, which is convenient for the placement of the bus bar 91 and helps in subsequent welding and forming.

[0041] like Figure 2 and Figure 8 As shown, in order to improve the safety of the squeezing of the clamping member 4, the clamping member 4 is manually operated. Specifically, the clamping member 4 includes a clamping vertical plate 41 fixedly connected to the tray 8, a main shaft 42 threadedly connected to the clamping vertical plate 41 toward the abutment end 7, and a push plate 44 rotatably connected to the end of the main shaft 42 close to the abutment end 7. The push plate 44 has at least one guide shaft 43 fixed toward the direction of the clamping vertical plate 41, and the guide shaft 43 is slidably connected to the clamping vertical plate 41. Among them, one end of the main shaft 42 is a polygonal structure, which can be suitable for a square ratchet wrench. The rotation of the square ratchet wrench can drive the main shaft 42 to rotate. The rotation of the main shaft 42 will drive the push plate 44 to move toward the abutment end 7 relative to the clamping vertical plate 41, and an insulating plate 45 is installed on the side of the push plate 44 facing the battery module 9. The push plate 44 drives the insulating plate 45 to squeeze the battery module 9, so that the battery module 9 is closely arranged. The main shaft 42 is twisted in the opposite direction, and the main shaft 42 drives the push plate 44 and the insulating plate 45 away from the battery module 9, so that the battery module 9 is loosened, thereby facilitating disassembly. This method can effectively improve the accuracy of manual verification.

[0042] like Figure 1-Figure 3 and Figure 8As shown, the side pressure plate includes at least one pair of main pressure plates 6, and the clamping member 4 and the abutting end 7 are installed with a fixing seat 46 on both sides of the side pressure plate distribution. The two ends of the main pressure plate 6 are detachably connected to the fixing seat 46, and the main pressure plate 6 is used to press the bus 91 onto the pole of the battery module 9. Among them, a manual clamp can be installed at the fixing seat 46 to fix the two ends of the main pressure plate 6 between the clamping vertical plate 41 and the abutting end 7. A card slot can also be opened at the top of the fixing seat 46 so that the two ends of the main pressure plate 6 are embedded in the card slot, and the bus 91 can be squeezed onto the pole through the main pressure plate 6. In addition, the two ends of the main pressure plate 6 can also be fixed to the fixing seat 46 by means of pins or bolts. When the main pressure plate 6 presses the bus 91, the contact part of the bus 91 and the pole leaks out, and this part is fixed by laser welding.

[0043] like Figure 1 、 Figure 5 and Figure 6 As shown, the side pressure plate also includes an auxiliary pressure plate 83 arranged on the same side of the main pressure plate 6. The auxiliary pressure plate 83 can tighten or loosen the battery modules 9 on both sides, wherein the auxiliary pressure plate 83 can be moved by a telescopic cylinder, such as a pneumatic cylinder or an electric cylinder. The telescopic cylinder is installed on the tray 8, and the telescopic end of the tray 8 is fixed to the auxiliary pressure plate 83. The telescopic end of the telescopic cylinder is extended to press the auxiliary pressure plate 83 on both sides of the battery module 9. When the telescopic end of the telescopic cylinder is loosened, the auxiliary pressure plate 83 and the two sides of the battery module 9 are loosened, and can be subsequently disassembled and replaced.

[0044] like Figure 3 、 Figure 5 and Figure 6 As shown, the tray 8 includes a support plate 81 for supporting the battery module 9, a long side upright plate 82 provided on the side of the support plate 81 away from its supporting surface, and an adapter plate 86 fixedly connected to the side of the secondary pressure plate 83 away from the side on which it presses the battery module 9. The adapter plate 86 is slidably connected to the support plate 81. Among them, the supporting surface of the support plate 81 can be provided with a groove for placing the battery module 9, and a number of lightweight holes are also opened. The long side upright plates 82 can be provided on both sides of the side pressure plate or on all four sides of the support plate 81. When the secondary pressure plate 83 slides along the support plate 81, the stability of the secondary pressure plate 83 clamping the battery module 9 can be improved.

[0045] Example 1:

[0046] Alternatively, a tooth groove may be provided on one side of the adapter plate 86, and a tooth block clamped in the tooth groove may be provided on the long side vertical plate 82, that is, in the form of a latch. If the battery module 9 needs to be released, only the tooth block needs to be pulled out.

[0047] Example 2:

[0048] The adapter plate 86 passes through the long side upright plate 82, and its end away from the auxiliary pressure plate 83 is fixedly connected to a connecting plate 89. The connecting plate 89 is fixedly connected to the long side upright plate 82 facing the corresponding side. The limiting shaft 85 is slidably connected to the long side upright plate 82, and an adjustment device 84 is provided at the end of the limiting shaft 85 passing through the long side upright plate 82. Among them, the number of adapter plates 86 can be set to multiple, and the ends of multiple adapter plates 86 away from the auxiliary pressure plate 83 are fixedly connected to the same connecting plate 89. The number of limit shafts 85 can be set to multiple, and the limit shafts 85 drive the adapter plates 86 and the connecting plates 89 to move relative to the long side vertical plate 82. The adjustment device 84 is installed on the long side vertical plate 82. The adjustment device 84 is preferably in the form of a manual clamp. At this time, the manual clamp is set at the end of the long side vertical plate 82 close to the limit shaft 85. At this time, the manual clamp rotates, and the auxiliary pressure plate 83 is driven by the limit shaft 85, the connecting plate 89 and the adapter plate 86 to squeeze toward the battery module 9, thereby achieving the compression and fixation of the battery module 9; when the manual clamp rotates in the opposite direction, the squeezing of the battery module 9 by the auxiliary pressure plate 83 can be released. In addition to this, other methods can also be used, as listed in Example 1.

[0049] like Figure 3 and Figure 4As shown, a top pressure piece 5 is provided on the opposite side of the supporting plate 81 on the bearing surface, and the two ends of the top pressure piece 5 are detachably connected to the pressing piece 4 and the abutting end 7. The top pressure piece 5 includes a pressing plate 53 pressed on the top of the battery module 9, and the two ends of the pressing plate 53 are fixed to the pressing piece 4 and the abutting end 7 by buckling, plugging, snapping or clamping. Preferably, a clamping method is adopted, and when disassembling, it is only necessary to toggle the clamp to complete the disassembly operation, thereby improving the convenience of disassembly; in addition, a pressing plate 52 is fixedly connected to the end of the pressing plate 53 away from the battery module 9, and the two ends of the pressing plate 52 are fixed to the pressing plate 52. A square groove is opened at the end to reduce the overall weight. Secondly, reinforcing ribs 51 are installed on both sides of the clamping plate 52. The setting of the reinforcing ribs 51 can effectively reduce the problem of deformation of the battery module 9 during the flipping process and improve the overall structural strength. At this time, the clamp is fixed at both ends of the clamping plate 52, and positioning plates 54 are installed at both ends of the clamping plate 52. The positioning plates 54 are positioned on the clamping member 4 and the abutment end 7 by means of a pin, and provide a mounting surface for the clamp. Handles are also installed at both ends of the clamping plate 52 to facilitate the grabbing and disassembly of the top pressure member 5 from the top of the battery module 9.

[0050] like Figure 1 、 Figure 2 and Figure 7 As shown, a torque transmission member 2 is provided at one end of the tray 8 that rotates. The torque transmission member 2 includes a reducer 21 fixed to the support member 1, and a connecting block 24 fixed to the output end of the reducer 21. The connecting block 24 is fixedly connected to one end of the tray 8. A locking member 3 is also installed on the tray 8 to adjust the flipping angle of the tray 8. Among them, the input shaft 22 is the input end of the reducer 21. A handwheel can be installed on the input shaft 22 to facilitate the user to turn it. After the handwheel is turned, the reducer 21 drives the connecting block 24 to rotate. The connecting block 24 is fixed to one end of the support plate 81, thereby driving the tray 8 and the battery module 9 to rotate, making it easy to change the posture of the battery module 9 and facilitating welding on different surfaces.

[0051] like Figure 1 and Figure 7As shown, the locking member 3 includes a fixed plate 31 mounted on one side of the reducer 21, a plug shaft 34 slidably mounted on the fixed plate 31, and a chuck 23 fixed to one side of the connecting block 24. The chuck 23 has a plurality of locking holes 25 on one end facing the plug shaft 34. The locking holes 25 are used to clamp and secure the ends of the plug shaft 34. A limit seat 33 is fixed to the fixed plate 31. A linear bearing is mounted on the limit seat 33. The plug shaft 34 is slidably connected to the limit seat 33 via the linear bearing. A handle 32 is also provided on the limit seat 33 for moving the plug shaft 34. By moving the handle 32, the plug shaft 34 can be moved away from the locking holes 25, thereby unlocking the tray 8 and the battery module 9. The reducer 21 and the connecting block 24 can then be driven to rotate. When the tray 8 and the battery module 9 are rotated to the desired position, the plug shaft 34 automatically engages with the subsequent locking holes 25 using a spring latch. In other words, the rotation of the multi-tray 8 is locked, thereby ensuring that the posture of the battery module 9 is fixed, allowing subsequent welding operations. Alternatively, a locking disc mechanism can be used, mounted on the hollow shaft of the reducer 21, to transmit torque through the locking disc. By sequentially tightening the bolts on the locking disc, the front and rear flanges are pressed against the open inner ring, which then compresses the hollow shaft of the reducer 21, thereby tightly connecting with the roller shaft through static friction and transmitting torque.

[0052] The following describes in detail the blade battery module welding, pressing, positioning, and flipping tooling for flipping and positioning the module.

[0053] First, the battery modules 9 are stacked and the end plates are installed on the support plate 81 based on the abutment end 7 in the module length direction.

[0054] Secondly, manually use a wrench to tighten the main shaft 42, set a pressure sensor on the push plate 44, and when the value on the pressure sensor meets the process requirements, stop tightening, manually install the top pressure piece 5 and riveting operation to complete the compression of the upper part of the module; manually install the bus 91 of the battery module 9, manually operate the adjustment device 84 to compress the lower part of the bus 91; manually install the main pressure plate 6, use pliers to fix it, and complete the compression of the upper part of the bus 91; use external equipment welding equipment to weld the compression surface of the battery module 9.

[0055] After completing the welding on one side, the shaft 34 is manually pulled out backward through the handle 32, and the shaft 34 is disengaged from the clamping hole 25. The hand wheel is manually rotated to complete the 180° flip of the battery module 9. The shaft 34 is manually pushed through the handle 32 and inserted into the clamping hole 25. After completing the compression of the battery module 9, the welding work on the other side can be carried out.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
