Abstract

[0002] In the era of energy demand transformation, traditional energy is gradually turning to new energy, and fuel vehicles are gradually being replaced by electric vehicles. The development of electric vehicles has also driven the demand for power batteries. Now there are many cells in power batteries, which need to be protected by buffer materials, including MPP foam with shock-absorbing and buffering functions, which can effectively absorb external impact and protect the battery cells from damage.
[0003] Electric vehicles need to ensure their safety during driving or charging and discharging, and avoid spontaneous combustion. Usually, a power battery consists of several modules, and a module consists of several cells. Buffer pads are needed inside the battery to play a role in shock absorption and buffering, thereby protecting the cells in the module. Due to market demand, production changes are being promoted, and the degree of automation is getting higher and higher, which also puts forward higher requirements for material molding. At present, this MPP foam die-cutting molding uses a saber, which has the following disadvantages:
[0004] 1. Since MPP foam is relatively soft and easy to deform, saber cutting results in uneven cuts and burrs, which cannot meet the needs of material production;
[0005] 2. When the number of sheets cut at one time is too large, the excessive force during cutting will cause extrusion and deformation, resulting in poor size;
[0006] 3. The saber cutting edge has burrs and debris, and the edge part cannot be used. A lot of garbage is generated after each cutting, and the blade is easily contaminated with foam debris, which is difficult to clean;
[0007] 4. When the saber cuts the foam, it cannot be leveled and fixed and is prone to deviation. When there are too many foam sheets, the cutting process will cause deviation. [Utility Model Content]
