As shown in fig. 6, the upper hot-cutting assembly 30 is mounted above the supporting assembly 20 and is used for cutting off an aluminum-plastic packaging film of a lithium battery cell, the upper hot-cutting assembly 30 includes a supporting rod 31 fixed on the box 10, a first driving cylinder 32 connected to the supporting rod 31, and an upper hot-cutting knife 34 connected to an output end of the first driving cylinder 32, the upper hot-cutting knife 34 moves downward under the driving of the first driving cylinder 32 to cut off the aluminum-plastic packaging film of the lithium battery cell, the supporting rod 31 is in an L-shaped structure, the supporting rod 31 plays a role of supporting the rest of the upper hot-cutting assembly 30, a plurality of diagonal braces and three gussets are arranged at the bottom of the supporting rod 31 to strengthen the structural stability of the supporting rod 31, the first driving cylinder 32 is used for driving the upper hot-cutting knife 34 to move towards or away from the upper surface of the supporting table 26, and as can be understood, the first driving cylinder 32 drives the upper hot-cutting knife 34 to move towards the upper surface of the lithium battery cell placed on the supporting table 26 until the upper hot-cutting knife 34 contacts with the aluminum packaging film on the lithium battery cell to complete the hot-cutting process.
Specifically, the internal structure of the upper hot knife 34 is specifically: the cutter comprises a cutter body and a heating element arranged in the cutter body, wherein the heating element can be a resistor sheet or an electric heating wire, and the electric heating element can be heated by electric current, so that the temperature of the upper hot cutter 34 is increased, meanwhile, in the actual processing process, the heating temperature range of the upper hot cutter 34 is 0-1000 ℃ and the heating time is 5-6 s, wherein the material of the packaging film coated on the periphery of the cutter body can be different when the temperature of cutting off the aluminum-plastic packaging film is 300-500 ℃, preferably 400 ℃, and the hot cutting process of the packaging film in different types of lithium battery cells can be completed by changing the temperature of the upper hot cutter 34.
The two sides of the upper hot knife 34 are provided with a blowing nozzle 38, the output end of the blowing nozzle 38 faces the bottom of the upper hot knife 34, the blowing nozzle 38 is used for separating the cut aluminum-plastic packaging film, wherein the blowing nozzle 38 is provided with an input end and an output end, the input end is the gas transmission end of the blowing nozzle 38, the gas blowing end of the blowing nozzle 38 can be connected with gas transmission equipment (such as an air pump, etc.), high-pressure gas is input into the blowing nozzle 38 through the gas transmission equipment, the blowing nozzle 38 blows the high-pressure gas to the position where the upper hot knife 34 cuts off the aluminum-plastic packaging film, and the adhesion of the high-pressure gas to the positive and negative electrode plates under the temperature effect of the upper hot knife 34 is avoided, and it is worth mentioning that in the embodiment, the blowing nozzle 38 is only arranged in the upper hot knife assembly 30, but the blowing nozzle 38 is not arranged in the lower hot knife assembly 40, the following reasons are as follows: firstly, the aluminum-plastic packaging film is not directly adhered to the periphery of the lithium battery cell, but is wrapped on the periphery of the lithium battery cell, when the upper hot-cutting assembly 30 cuts off the aluminum-plastic packaging film on the upper surface of the lithium battery cell, high-pressure gas is output through the blowing nozzle 38, and because the aluminum-plastic packaging film is only contacted with positive and negative pole pieces and is not adhered, the aluminum-plastic packaging film is integrated, after the aluminum-plastic packaging film on the upper surface of the lithium battery cell is cut off, the disassembled lithium battery cell is taken out, the aluminum-plastic packaging film can automatically fall off from the lithium battery cell, and the blowing nozzle 38 is not required to be arranged in the lower hot-cutting assembly 40; then, because the lithium battery cell is placed on the supporting table 26, the aluminum-plastic packaging film on the lower surface of the lithium battery cell is pressed on the supporting table 26 under the gravity of the lithium battery cell, after the lower hot-cutting assembly 40 cuts off the aluminum-plastic packaging film on the lower surface of the lithium battery cell, if the meaning of blowing the cutting position by using the blowing nozzle 38 is not great, the disassembled lithium battery cell is taken out, and the aluminum-plastic packaging film still falls off from the lithium battery cell, so that the blowing nozzle 38 is not necessary to be added in the lower hot-cutting assembly 40, and certain energy waste is caused.
As shown in fig. 8, the lower hot-cutting assembly 40 is mounted below the supporting assembly 20 and is used for cutting off an aluminum-plastic packaging film of a lithium battery cell, the lower cutter assembly 40 includes a mounting bracket 42 fixed in the box 10, a second driving cylinder 41 connected to one side of the mounting bracket 42, and a lower hot-cutting blade 44 connected to an output end of the second driving cylinder 41, the lower hot-cutting blade 44 is driven by the second driving cylinder 41 to move upwards to cut off the aluminum-plastic packaging film of the lithium battery cell, the second driving cylinder 41 is used for driving the lower hot-cutting blade 44 to move towards or away from a lower surface of the supporting table 26, and as can be understood, the second driving cylinder 41 drives the lower hot-cutting blade 44 to move towards the lower surface of the lithium battery cell placed on the supporting table 26 until the lower hot-cutting blade 44 contacts with the aluminum-plastic packaging film on the lithium battery cell, so as to complete the hot-cutting process, wherein the structure of the lower hot-cutting blade 44 is completely consistent with the structure and the heating range of the upper hot-cutting blade 34, and the directions of the edges of the two edges are opposite.
The box 10 is provided with a cutting hole through which the lower hot knife 44 can pass, and a cutting gap through which the lower hot knife 44 can pass is reserved between the two support tables 26, and as most of the lower hot knife assembly 40 is arranged in the box 10, only in the cutting process of the lower hot knife 44 for cutting the aluminum plastic packaging film, the cutting hole and the cutting gap are repeatedly penetrated until the lower hot knife 44 contacts with the aluminum plastic packaging film on the surface of the lithium battery cell to complete the hot cutting process, and meanwhile, when the lithium battery cell is placed, the lithium battery cell needs to be ensured to be positioned above the cutting gap, so that the lower hot knife 44 is ensured to be contacted with the aluminum plastic packaging film.
As shown in fig. 2, in this embodiment, the front side of the box 10 is hinged with a box door 11, the bottom of the box 11 is connected with a universal wheel 12, and a worker can enter the box 10 by opening the box door 11, so as to complete the overhaul of the lower hot-cutting assembly 40, and meanwhile, the universal wheel 12 can enable the hot-cutting mechanism for disassembling the scrapped power lithium battery cells provided in this embodiment to be freely moved, so that the hot-cutting mechanism is not limited by a working environment.
