step 320: and after the locking support beam is completely inserted into the slot, releasing and removing the pressing tool.
It should be noted that, in the present invention, the specific structures and operation modes of the clamping tool and the pressing tool are the prior art, and are not described herein again.
In conclusion, the split mounting beam can realize automatic boxing of the battery pack, simplify the assembly process, reduce the assembly cost and improve the automatic production efficiency;
according to the split type mounting beam, the battery pack is initially fixed and limited by the positioning support beam, and the slot of the positioning support beam is used as the accommodating space of the clamping tool, so that the clamping tool is not influenced by the overall height of the mounting beam, the battery pack can be placed at a proper position at one time, and additional pressing acting force is not required to be applied to the battery pack, so that the problem of bus bar welding quality is avoided, and the use safety of a power supply system is improved; the locking support beams apply extrusion force to the two ends of the battery pack, so that the battery monomers of the battery pack are tightly connected together, and the reliability of the battery pack in the use process is ensured;
according to the split type mounting beam, the inner surface of the slot and the top surface of the locking support beam can be enclosed with the end surface of the battery pack to form an accommodating space for accommodating a wiring harness and/or an electric device, so that the purpose of reasonably utilizing the space is achieved, and the routing in the battery pack is clean;
according to the battery pack, the battery pack without the module structure is fixed by the split mounting beam, and an additional pressing acting force is not required to be applied to the battery pack, so that the problem of welding quality of the bus bar is effectively solved, and the use safety of the battery pack is improved; the two locking support beams simultaneously apply extrusion force to the two ends of the battery pack, so that the battery monomers of the battery pack are tightly connected together, and the reliability of the battery pack in the use process is ensured;
the assembling method of the battery pack uses the split type mounting beam, so that the assembling method can realize automatic boxing of the battery pack, simplifies the assembling process, and the assembled battery pack has the advantages of safe and reliable use.
