[0026] 1. The present invention provides a module guiding assembly on the inner side of the guiding side groove, and the first group of battery modules grabbed is placed above the stacking bottom plate. When the second group of battery modules is placed, the module guiding assembly works to make the guiding anti-skid seat support the bottom of the battery module and drive it to move slowly downward. The guiding anti-skid seat continues to support the battery module during the driving descent process, and the anti-skid seat contracts to store the guiding anti-skid seat into the guiding side groove, releasing the blocking of the guiding anti-skid seat on the battery module to achieve docking of the two groups of battery modules, preventing the natural falling of the battery cells from causing collision between the two groups of battery cells and causing damage.

[0027] 2. The present invention opens a discharge groove on the inner side of the top of the guide side groove. When the second group of battery modules is about to be aligned and contacted with the top of the first group of battery modules, the module guide assembly stops working, and the in-position driving hand rod drives the slotted guide block to move above the outer end of the battery module, and the storage hand rod drives the limiting clamping plate to contact the outer end of the battery module. During the resetting process of the module guide assembly, the limiting clamping plate clamps and limits the outer end of the battery module, so that the battery module remains in a stable state, preventing the position of the upper battery module after vertical alignment from shifting, which will have an adverse effect on the stacking assembly process, and further improving the stacking quality of the battery module.

[0028] 3.

The horizontal distance between the two groups of battery module stacking racks is adjusted according to the different specifications of the battery modules to ensure that the internal stacking space matches the battery modules, ensuring that each battery module can be tightly and safely placed in the stacking rack, reducing the friction and collision caused by shaking of the battery modules during transportation and use, reducing the risk of short circuits caused by physical damage, and presetting the stacking space parameters according to the battery module specifications to achieve fast and accurate stacking of battery modules, thereby improving production efficiency.

[0029] 4. The present invention installs a stacking bottom plate at the output end of the electric flip seat. After the battery module stacking is completed, the electric flip seat flips downward to make the stacked battery module fall onto the unloading conveying device. The electric flip seat realizes automatic flipping and falling of the battery module, reduces manual operation, and improves the automation degree of stacking production. The automatic flipping and conveying process is rapid and continuous, which greatly shortens the production cycle of the battery module, reduces errors and mistakes caused by human factors, improves the accuracy and consistency of battery module stacking, and adapts to the production needs of battery modules of different specifications and types. Automatic flipping and unloading ensures the continuous use of the battery module stacking rack, and improves the overall production efficiency of battery module stacking.

[0044] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 , an embodiment provided by the present invention: an adjustable battery module stacking device and a method of using the same;

[0045] The battery module stacking frame 2 comprises a stacking seat 1, a battery module stacking frame 2 and a module guide assembly. The battery module stacking frame 2 is arranged above the stacking seat 1. A guide side groove 6 is provided on the inner wall of the battery module stacking frame 2. A module guide assembly is provided on the inner side of the guide side groove 6. The module guide assembly comprises a vertical stabilizing groove 26, a lifting hand bar 27, an L-shaped lifting platform 28, a falling hand bar 29 and a guiding anti-slip seat 30. The vertical stabilizing groove 26 is arranged on the bottom wall of the guiding side groove 6. The lifting hand bar 27 is installed on the inner side of the vertical stabilizing groove 26. The L-shaped lifting platform 28 is installed on the telescopic end of the lifting hand bar 27. The falling hand bar 29 is installed on the inner side of the L-shaped lifting platform 28. The guiding anti-slip seat 30 is installed on the telescopic end of the falling hand bar 29.

[0046] The guide side groove 6 provides an installation position for the module guide assembly, and the vertical stabilizing groove 26 provides an installation position for the lifting handle 27 while providing it with space for movement. When the second group of battery modules is placed, the lifting handle 27 drives the L-shaped lifting platform 28 to rise so that the guiding anti-skid seat 30 supports the bottom of the battery module and drives it to move slowly downward. The lifting handle 27 drives the guiding anti-skid seat 30 to continue to support the battery module during the descent process. When the two groups of battery modules are about to contact, the stopping handle 29 works to retract and store the guiding anti-skid seat 30 into the guiding side groove 6, releasing the obstruction of the guiding anti-skid seat 30 to the bottom of the battery module. The upper battery module falls onto the bottom battery module to realize the docking of the two groups of battery modules, preventing the natural falling of the battery cells from causing collisions between the two groups of battery cells and thus causing damage. The guidance of the battery module stacking process makes the stacking process smoother and improves the stacking quality.

[0047] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 , an adjustable battery module stacking device and method of using the same;

[0048] It includes a guide side groove 6, a discharge groove 7 and a limit pressing plate 35. The vertical stabilizing groove 26 is provided on the bottom wall of the guide side groove 6. The lifting hand rod 27 is installed on the inner side of the vertical stabilizing groove 26. The L-shaped lifting platform 28 is installed on the telescopic end of the lifting hand rod 27. The falling hand rod 29 is installed on the inner side of the L-shaped lifting platform 28. The guide anti-skid seat 30 is installed on the telescopic end of the falling hand rod 29. The top inner side of the guide side groove 6 is provided with a discharge groove 7. The inner wall of the discharge groove 7 is provided with a position driving hand rod 31. The telescopic end of the position driving hand rod 31 is provided with a slotted guide block 33. The top inner side of the discharge groove 7 is provided with a limit sliding groove 32, and the top end of the slotted guide block 33 slides on the inner side of the limit sliding groove 32. The inner side of the slotted guide block 33 is provided with a storage hand rod 34. The telescopic end of the storage hand rod 34 is provided with a limit pressing plate 35.

[0049] When the second group of battery modules is about to be aligned and contacted with the top of the first group of battery modules, the module guide assembly stops working, and the unloading chute 7 provides an installation position for the in-place driving handle 31, and the storage handle 34 is installed on the inner side of the slot of the slotted guide block 33. When the two groups of battery modules are about to contact, the storage handle 34 drives the limiting clamping plate 35 to contact with the outer end of the upper battery module, and the limiting slide groove 32 ensures the stability of the limiting clamping plate 35 when it moves horizontally. During the resetting process of the module guide assembly, the limiting clamping plate 35 clamps and limits the outer end of the battery module to keep the battery module in a stable state, and prevents the upper battery module from shifting left and right after vertical alignment, which has an adverse effect on the stacking assembly process. According to the production requirements of the battery modules, multiple groups of battery modules are stacked and assembled in sequence. After stacking, the battery modules are fastened by steel belt bundling, bolt fixing, tooling fixing, etc. to prevent displacement or deformation during subsequent transportation and assembly.

An anti-deflection frame 11 is installed on the front of the stacking seat 1, and the anti-deflection frame 11 is located at the front end of the discharge conveying device 10.

[0052] The support platform 8 supports the stacking seat 1, and the bottom opening 13 provides a falling space for the stacked battery modules. After the battery modules are stacked, the electric flip seat 14 drives the stacking bottom support plate 15 to flip downward so that the stacked battery modules fall onto the unloading conveying device 10. The unloading conveying device 10 conveys the stacked battery modules to the outside of the stacking seat 1 through the anti-skew frame 11. The electric flip seat 14 realizes the automatic flipping and falling of the battery modules, reduces manual operation, improves the accuracy and consistency of battery module stacking, and adapts to the production needs of battery modules of different specifications and types. The automatic flipping and unloading ensures the continuous use of the battery module stacking frame 2, and does not cause the stacking waiting of the next group of battery modules due to the unloading time process, thereby improving the overall production efficiency of the battery module stacking. The automatic stacking table and electric flip seat 14 using modular design and intelligent control technology are convenient for subsequent upgrades and maintenance work.

[0053] See also Figure 1 and Figure 2 , an adjustable battery module stacking device and method of using the same;

[0054] It comprises a stacking seat 1, a pitch-adjusting slot 5 and a battery module stacking rack 2. The battery module stacking rack 2 is arranged above the stacking seat 1.

[0055] The rectangular slot 24 provides an installation position for the distance adjustment motor 25. The distance adjustment motor 25 drives the threaded rod 22 to rotate so that the horizontal drive seat 23 moves inside the distance adjustment flat slot 5 to drive the battery module stacking rack 2 to adjust the position in the horizontal direction. According to the different specifications of the battery modules, the horizontal distance between the two groups of battery module stacking racks 2 is adjusted to ensure that the internal stacking space matches the battery modules. The round pillars 37 support the two groups of battery module stacking racks 2 respectively, so as to achieve the docking and distance adjustment operations of the two groups of battery module stacking racks 2, ensuring that each battery module can be tightly and safely placed in the battery module stacking rack 2, reducing the friction and collision caused by shaking of the battery modules during transportation and use, reducing the risk of short circuit caused by physical damage, and presetting the stacking space parameters according to the battery module specifications to achieve fast and accurate stacking of battery modules, thereby improving production efficiency;

[0056] The optimized stacking space can accommodate battery modules to the maximum extent, increase the capacity of the overall energy storage system, and improve stacking stability. Tightly stacked battery modules can support each other, enhancing the stability and strength of the entire stacking structure. A good stacking layout helps air circulation, optimizes heat dissipation, and reduces safety hazards caused by overheating of battery modules. A reasonable stacking layout can reduce the failure rate of battery modules caused by physical damage or overheating.
