Detailed description of the invention
This utility model is further illustrated below in conjunction with the accompanying drawings with specific embodiment.
As shown in Figure 1 to 4, a kind of hot equipment complex for battery pole piece with barrier film bonding, including heater 1, the continuous tape deck of pressue device 2, first, the second continuous tape deck, diaphragm support device 8, framework 9 and heating controller 10.
First continuous tape deck and the second continuous tape deck structure are identical, all include by multiple pressure rollers 4, the endless belt 5 being winded at multiple pressure roller 4 two ends driving roller 3 to drive and are evenly distributed on the multiple heating platens 6 on the outer surface of endless belt 5.Pressure roller 4 is two ends thin dumbbell structure thick, middle.The upper inner of the lower inside of the endless belt 5 of the first continuous tape deck and the endless belt 5 of the second continuous tape deck is all close to be provided with the roller group 7 being formed by connecting by multiple rollers.
Heater 1 is close to the inner side of roller group 7 and is arranged, and pressue device 2 is fixed on framework 9 top, and multiple pressure rollers 4 of the first continuous tape deck are connected with pressue device 2 by support, and multiple pressure rollers 4 of the second continuous tape deck are fixed on framework 9 bottom by support.In diaphragm support device 8 is fixing on the frame 9, and the outer surface of upper of the endless belt 5 of the upper surface of diaphragm support device 8 and the second continuous tape deck is generally aligned in the same plane.
Heater 1 is the rectangular structure of hollow, inner homogeneous is distributed multiple heating element heater 11, it is hot pressing face that rectangular structure is close to the one side of roller group 7, remaining five face is equipped with heat insulation layer 12, and adiabator can be glass fibre, asbestos, rock wool, silicate or aerogel blanket, evacuated panel etc..The outfan of heating controller 10 is connected with the input of heating element heater 11.The mode of heating of heating element heater 11 can be one or more mixing in Resistant heating, heat-conducting oil pipes heating, infrared heating, medium-high frequency sensing heating or microwave heating, and heating-up temperature is adjustable between room temperature to 300 DEG C.Heat insulation layer 12 reduces the heat transfer of heating element heater 11 and periphery, serves insulation and the effect of energy efficient.
Pressue device 2 is cylinder or oil cylinder, it is possible to provide the pressure of 0 to 1000kgf.
Driving roller 3 to be connected with motor, pressure roller 4 is connected by belt or chain with driving roller 3.Move along with the rotation of pressure roller 4 in endless belt 5, and when carrying out hot pressing, it is possible to realize continuous tape transport.Distance between two adjacent rollers along the setting of heating platen 6 direction of transfer of roller group 7, less than the half of heating platen 6 length, so can ensure that heating platen 6 the most at least contacts two or more roller when transmission, so that pressure is uniform during hot pressing.Acting primarily as service portion during hot pressing is divided into heating platen 6, the effect of endless belt 5 to be to connect heating platen 6, and can move around the cambered surface of pressure roller 4.Endless belt 5 is flexible-belt, uses exotic material to prepare, can be the one therein such as high-strength Thief zone polyester canvas or duck.Heating platen 6 material palpus hardness is high and heat conductivity is good, and material can be the one in rustless steel, copper coin, aluminium alloy, aluminium nitride ceramics, aluminium oxide ceramics, boron nitride ceramics, politef.
Anode uses LiFePO 4 material, and collector is aluminium foil, and negative pole uses artificial graphite material, and collector is Copper Foil.After positive and negative collector completes coating, baking, roll-in, cuts into bar, it is cut into little pole piece regular according to positive and negative plate design size respectively.
Operation principle of the present utility model:
Pole piece 13 and barrier film 14 at least as surface coating, be placed on evenly distributed for some pole pieces 13 on barrier film 14.When pole piece 13 and barrier film 14 are entered between the first continuous tape deck and the second continuous tape deck in the direction of the arrow by diaphragm support device 8, pressue device 2 provides certain pressure, the pressure roller 4 of the first continuous tape deck moves downward under the effect of pressue device 2, so that the first continuous tape deck moves closer to the second continuous tape deck, applying certain pressure to pole piece 13 and barrier film 14, device for simultaneous heating 1 passes through heating platen 6 by thermal energy conduction to pole piece 13 and barrier film 14.Gluing on barrier film 14 or pole piece 13 melts under the effect of heat energy, and makes pole piece 13 be bonded together with barrier film 14 under stress, and continues to move along entrance next process in the direction of the arrow by diaphragm support device 8, and hot pressing completes.
Pressure roller 4 is connected to drive roller 3, and rotate under the effect driving roller 4, and band ring-shaped belt 5 moves, owing to pole piece 13 and barrier film 14 are when entering between the first continuous tape deck and the second continuous tape deck, barrier film 14 is the outer surface of upper of the endless belt 5 being close to the second continuous tape deck, so make equipment that barrier film 14 can also be driven when hot pressing to move simultaneously, thus the Continuous Heat realizing barrier film 14 and pole piece 13 is combined.
