[0034] In conjunction with Figures 1 to 4 As shown, according to specific embodiments of the present application, a battery module aluminum bar welding device is provided.
[0035] Specifically, the welding device comprises a welding clamp 10 and a lifting part. The welding clamp 10 comprises a pressing plate 11 arranged at the top of the welding clamp 10, and the lifting part is arranged below the pressing plate 11, and the lifting part and the pressing plate 11 form a containing space for containing the battery module 20. The lifting part has a locking position moving towards the pressing plate 11 to lock the battery module 20, and the lifting part has a releasing position moving away from the pressing plate 11 to release the battery module 20.
[0036] The technical scheme of the present application is applied, by designing the combination of the welding clamp 10 and the lifting part, the lifting part is moved towards the pressing plate 11 to the locking position during welding to fix the battery module 20, thereby solving the pressing and positioning problem during manual welding of the aluminum bar 22, ensuring the position accuracy during welding, and improving the welding quality and production efficiency. The present application solves the problem of low single-point welding efficiency caused by the difficulty of positioning the battery module in the prior art.
[0037] Further, as Figure 2As shown, the welding fixture 10 further comprises a fixed plate 12 arranged below the pressing plate 11 and located at the side of the battery module 20 close to the pressing plate 11, the fixed plate 12 is detachably connected with the battery module 20, and the fixed plate 12 is provided with a positioning structure for positioning the aluminum bars 22 of the battery module 20, and at least part of the aluminum bars 22 are exposed below the pressing plate 11 through the positioning structure.
[0038] At least part of the aluminum bars 22 are exposed below the pressing plate 11 through the positioning structure, which means that the welding surface of the aluminum bars 22 can be directly pressed by the pressing plate 11 without being blocked by the fixed plate 12.
[0039] Specifically, the fixed plate 12 and the battery module 20 are detachably connected, for example, using screws, quick buckles or other connection methods. Such design can make the fixed plate 12 quickly detachable from one battery module 20 and then installable on another battery module 20. The detachable connection design increases the flexibility of the welding fixture 10, which can adapt to battery modules 20 of different sizes and shapes, and reduces the replacement and adjustment cost of the equipment.
[0040] Optionally, the size of the aluminum bars corresponds to the size of the positioning structure, and the aluminum bars 22 are placed in the positioning structure to fix the aluminum bars 22, which can avoid movement of the aluminum bars 22 in the x and y directions during welding. The function of the positioning structure is to ensure the accurate alignment of the aluminum bars 22 when placed, and to avoid poor welding caused by position deviation during welding, such as virtual welding, uneven welding, etc. Through accurate positioning, the positioning error caused by manual operation can be greatly reduced, and the consistency and reliability of welding can be improved.
[0041] Specifically, the positioning structure comprises a plurality of positioning grooves, the plurality of positioning grooves are arranged in two rows along the width direction of the fixed plate 12, and the plurality of positioning grooves are arranged at intervals, and the positioning grooves are used for placing at least part of the aluminum bars 22. The design principle of the positioning groove is to position the aluminum bars through the shape and position of the groove, to ensure the position stability of the aluminum bars during welding, and to avoid deformation or position deviation of the aluminum bars caused by single-point positioning.
[0042] The positioning grooves are arranged in two rows along the width direction of the fixed plate 12, and the positioning grooves in each row are kept at a certain interval, which helps the uniform placement of the aluminum bars 22 on the fixed plate 12, and the aluminum bars 22 are in direct contact with the battery module 20.
[0043] Optionally, the positioning structure can also be designed as a hole structure, a groove structure (with a notch on the wall), or a channel structure with a certain length.
[0044] Specifically, the middle part of the pressing plate 11 is provided with a hollow structure for the welding arm to pass through to weld the aluminum row 22. By providing a hollow structure in the middle part of the pressing plate 11, sufficient space is provided for the welding arm to accurately align and weld the aluminum row 22, while avoiding obstruction of the welding arm by the pressing plate 11, thereby improving welding efficiency.
[0045] Further, the welding fixture 10 further comprises a mounting frame 13 connected with the lifting part, at least one guide rail 26 and / or at least one guide plate are arranged on the mounting frame 13. The connection of the mounting frame 13 with the lifting part provides support and guidance for the lifting part, ensuring the stability and accuracy of the vertical movement of the lifting part, while the design of the guide rail and the guide plate provides further guidance and positioning function.
[0046] Specifically, two guide rails 26 are arranged in the embodiment, and the two guide rails 26 are arranged in parallel, one side of each guide rail 26 is connected with the mounting frame 13, and the other side of the guide rail 26 abuts against the mounting table 18. The mounting table 18 can move along the length direction of the guide rail 26, and a handle 27 is arranged at the front end of the mounting table 18. The operator can easily pull out or push in the mounting table 18 along the guide rail 26 by gripping the handle 27, so as to realize the quick mounting and dismounting of the battery module.
[0047] Optionally, one side of the guide rail 26 is fixedly connected with the mounting frame 13, which ensures the stability and reliability of the guide rail in the overall structure of the welding fixture. The guide rail 26 can be a linear guide rail or a sliding rail, which ensures the smoothness and stability of the mounting table 18 during movement. The combination of the handle 27 and the guide rail 26 significantly speeds up the mounting and dismounting speed of the battery module 20. The operator only needs to push or pull the handle 27 slightly to complete the positioning and movement of the mounting table 18, without the need for additional tools or equipment, which simplifies the operation process and improves the turnover rate of the production line.
[0048] It should be further explained that two connecting rods 14 are arranged at both ends of the pressing plate 11, and the two connecting rods 14 arranged at the same side are arranged at intervals, and the connecting rods 14 are fixedly connected with the mounting frame 13. The combination of the pressing plate 11 and the connecting rod 14 not only ensures the stable pressing of the aluminum row 22 during welding, but also improves the structural strength and stability of the entire welding fixture 10, providing a solid guarantee for the efficient welding of the battery module.
[0049] Specifically, two connecting rods 14 are arranged at both ends of the pressing plate 11, and the two connecting rods 14 arranged at the same side are arranged at intervals, which ensures that the pressing member can obtain uniform support when performing the pressing action on the aluminum row, preventing deformation of the pressing member or positioning error of the battery module due to uneven distribution of the pressing force.
[0050] Optionally, the connecting rod 14 is fixedly connected with the mounting frame 13, so as to stably install the pressing plate 11 in the structure of the welding fixture, and ensure the stability and reliability of the pressing plate 11 during operation. The connecting mode of the connecting rod 14 and the mounting frame 13 can be bolt connection, welding or other fixing modes.
[0051] Further, the lifting part comprises a power device 25, a mounting table 18 and a lifting table 24. The power device 25 is connected with the mounting frame 13; the lifting table 24 is connected with the output end of the power device 25; the mounting table 18 is detachably placed on the lifting table 24, and the mounting table 18 is used for carrying the battery module 20; the battery module 20 is located on the mounting table 18, and the upper surface of the mounting table 18 is provided with a limiting block for limiting the battery module 20; wherein the power device 25 can drive the mounting table 18 to move in the vertical direction, so that the mounting table 18 drives the battery module 20 to be located at the locking position and the release position. The vertical movement of the lifting table 24 and the mounting table 18 is driven by the power device 25, so as to realize the stable positioning and quick release of the battery module 20 during the welding process, thereby improving the welding efficiency and operation safety, avoiding the welding defects caused by inaccurate positioning, and improving the production rhythm and reducing the non-production time through the quick release function.
[0052] Optionally, the power device 25 is arranged below the mounting table 18, and the power device 25 is connected with the mounting frame 13 and is responsible for providing the power required for the movement of the lifting table 24. The power device 25 can accurately control the up-down movement of the lifting table 24, so as to ensure that the battery module 20 can be stably located at the locking position during the welding process, that is, the best welding position matched with the pressing plate 11 and the fixing plate 12. After the welding is completed, the power device 25 drives the lifting table 24 to move downward to the release position, so as to facilitate the quick unloading of the battery module 20 after the welding is completed, and thereby improve the flow speed of the production line.
[0053] Specifically, the power device 25 can be a motor, a pneumatic cylinder, a hydraulic cylinder or other power sources capable of realizing stable vertical movement. The power device 25 is connected with the upper surface of the mounting frame 13 or is arranged through the mounting frame 13.
[0054] Specifically, the output end of the power device 25 on one side of the lifting platform 24 is connected, the other side of the lifting platform 24 is in abutment with the mounting platform 18, the width dimension of the lifting platform 24 is greater than the width dimension of the mounting platform 18, and the length dimension of the lifting platform 24 is less than the length dimension of the mounting platform 18. The other side of the lifting platform 24 is in abutment with the mounting platform 18, which allows the mounting platform 18 to be adjusted in position on the lifting platform 24 to adapt to battery modules 20 of different sizes. At the same time, the width dimension of the lifting platform 24 is greater than the width dimension of the mounting platform 18, which provides additional stability to prevent the mounting platform 18 from shaking or tipping over during lifting. The length dimension of the lifting platform 24 is less than the length dimension of the mounting platform 18, which can further save the installation space of the welding device and save costs.
[0055] Optionally, one side of the lifting platform 24 is directly connected to the output end of the power device 25, which means that the power device 25 can directly act on the lifting platform to provide stable driving force required for lifting. The connection of the output end with the lifting platform 24 ensures that the platform surface of the lifting platform 24 can remain horizontal during lifting, avoiding positioning errors caused by tilting.
[0056] Specifically, in this embodiment, the upper surface of the mounting platform 18 is provided with four limiting blocks, which are arranged on both sides of the battery module for limiting the battery module 20. During rapid lifting, the battery module 20 can also remain stable to prevent accidental sliding.
[0057] Further, the welding fixture 10 further comprises a pressing member fixedly connected with the pressing plate 11, the pressing member is arranged above the positioning groove, and a plurality of pressing members are arranged at intervals. The pressing member is fixedly connected with the pressing plate 11 to press the aluminum bars 22 above the positioning groove, ensuring the stability of the position of the aluminum bars 22 during welding, and avoiding poor welding caused by vibration or movement of the aluminum bars 22. The implementation effect is to improve the precision and stability of aluminum bar welding, reduce the poor welding rate, and improve the production efficiency.
[0058] Specifically, the pressing member comprises a spring 16 and a pressing block 17. One end of the spring 16 is connected with the pressing plate 11, and the other end of the spring 16 is connected with the pressing block 17. When the battery module 20 is in the locked position, the pressing block 17 is in abutment with the aluminum bars 22. The spring 16 exerts a force to make the pressing block 17 abut against the aluminum bars 22 when the battery module 20 is in the locked position, thereby pressing the aluminum bars 22 and ensuring the stability of the position of the aluminum bars during welding, which can avoid displacement of the aluminum bars in the Z direction.
[0059] Optionally, the number of pressing members corresponds to the number of positioning grooves, which can ensure that all the aluminum bars 22 can be effectively fixed during welding.
[0060] Specifically, as shown in Figure 4As shown, one end of the spring 16 is connected to the pressing plate 11, and the other end is connected to the pressing block 17. The spring 16 is designed to provide adjustable pressing force, ensuring that the aluminum row 22 is subjected to appropriate pressing force in different situations, avoiding deformation of the aluminum row 22 due to excessive pressure.
[0061] Specifically, the pressing block 17 directly abuts against the aluminum row 22. The shape and size of the pressing block 17 need to match the surface features of the aluminum row 22, so as to reduce damage to the surface of the aluminum row while maintaining the stability of the aluminum row. The material selection of the pressing block is also crucial, and materials that are wear-resistant and do not react with aluminum, such as stainless steel or special engineering plastics, should be used. The precise abutment of the pressing block 17 and the aluminum row 22, combined with the fixed plate 12 and the positioning structure, provides an accurate pressing reference for the welding robot, enabling multi-point welding to be completed at one point at a time, improving welding efficiency and welding quality.
[0062] Further, the battery module aluminum row welding device also includes a limiting plate, which includes a first component segment 41 and a second component segment 42. The first component segment 41 is fixedly connected to the mounting frame 13; one end of the second component segment 42 is connected to the first component segment 41, and the other end of the second component segment 42 abuts against the mounting table 18. The second component segment 42 is arranged at an angle with the first component segment 41, and the length of the second component segment 42 is less than the length of the guide rail 26. The limiting plate can limit the position of the mounting table, ensuring that the battery module 20 is placed in the correct position, ensuring the stability of the mounting table during the rising and falling process, and avoiding poor welding caused by the displacement of the mounting table.
[0063] Specifically, the first component segment 41 is fixedly connected to the mounting frame 13, serving as the base of the limiting plate, which is used to fix the limiting plate as a whole in the structure of the welding device, ensuring the stability and reliability of the limiting plate.
[0064] One end of the second component segment 42 is connected to the first component segment 41, and they form a certain angle. This design allows the second component segment 42 to extend to the position abutting against the mounting table 18. The length of the second component segment 42 is less than the total length of the guide rail 26, to avoid interference when the mounting table 18 moves, while ensuring the limiting effect of the second component segment 42 on the mounting table, ensuring the stable positioning of the battery module 20 during welding.
[0065] It should be further explained that before the welding operation, the operator places the battery module 20 at the limited position on the mounting platform, detachably connects the fixing plate 12 to the battery module 20, then places the aluminum busbar 22 in the positioning groove on the fixing plate 12, and uses the handle 27 to move the mounting platform 18 along the length direction of the guide rail 26. According to the length position of the second section 42 of the limiting plate, the mounting platform with the battery module is placed in the correct position. The power device 25 is started to control the up and down movement of the lifting platform 24, so that the battery module 20 can be stably locked in the locking position during the welding process.
[0066] Specifically, such as Figure 3 As shown, the fixing plate 12 has multiple positioning holes 23, which are located between two rows of positioning slots. Welding points 30 are provided on the aluminum busbar 22, surrounding the positioning holes 23. When the battery module is in the locked position, the clamping component presses the aluminum busbar 22, and the welding robot then welds the aluminum busbar 22 through the hollow structure of the clamping plate 11. The design of the positioning holes 23 provides a precise welding positioning reference for the welding robot, ensuring that the welding head can accurately align with the welding points 30.
[0067] Optionally, each positioning hole 23 corresponds to four welding points 30. This arrangement of positioning holes enables the welding robot to weld four welding points 30 at once through the positioning holes 23, which significantly improves welding efficiency.
[0068] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0069] 1. This utility model, by designing a combination of welding fixture and lifting part, moves the lifting part toward the clamping plate to the locking position during welding to fix the battery module, thereby solving the clamping and positioning problems during manual welding of aluminum busbars, ensuring positional accuracy during the welding process, and improving welding quality and production efficiency.
[0070] 2. By introducing structures such as guide rails and limiting plates, this solution not only ensures the stability and safety of the welding process, but also optimizes the loading and unloading process of battery modules, reduces human intervention during operation, lowers operational risks, and improves the overall operational stability of the equipment.
[0071] 3. By designing welding fixtures and using a multi-point simultaneous welding method, this solution enables multi-point welding of the aluminum busbar of the battery module in a single operation. Compared with the traditional single-point welding process, this greatly improves welding efficiency, reduces production time, and enhances the turnover rate and production capacity of the production line.
