Description
Technical field
The utility model is related to lithium battery coiling winding technologe technical field, especially a kind of diaphragm hot knife device.
Background technology
The lithium-ion-power cell of winding process production, needs to be spaced from each other positive/negative plate using diaphragm, i.e., according to " one
The sequence of layer diaphragm, one layer of cathode, one layer of diaphragm, one layer of anode " wound on together, and in tail portion using cutter by positive/negative plate
It is cut off with diaphragm, finally sticks the making that adhesive tape completes battery core；The cutter and diaphragm cutter of positive/negative plate are complete using shearing mechanism
At rupturing operation, service life is generally all at 1,000,000 times or more；Positive/negative plate is breaking inside, and needing to dismantle can just reach,
But diaphragm, the effect of cut-out is but can directly be seen that, so requiring diaphragm cut-out that must keep neat and consistent in technique.
It is special due to diaphragm after use after a period of time using shearing mechanism when carrying out cut-out diaphragm and working
Different degrees of abrasion can all occur in material, cutter, cause the gap between cutter to increase, at this moment will appear and can't cut or cut off
Afterwards with small tail the phenomenon that, (is broken by external force when sub-fraction is not cut off and causes), and diaphragm, which can't cut, can directly contribute battery core report
It is useless, the problems such as diaphragm with small tail needs manually to trim, causes the waste of time and manpower.
Invention content
The utility model technical issues that need to address are to provide a kind of lithium battery diaphragm cutting blade abrasion of capable of effectively reducing
Cutter.
In order to solve the above technical problems, the diaphragm hot knife device of the utility model, including cutter, the cutter are fixed
On the heat-insulated pedestal of hot knife, the thermal conduction base being in contact with cutter, the heat are fixed on the heat-insulated pedestal of hot knife
Heating rod is provided in conducting submount, the heating rod is connected by heating rod power cord with power supply.
Further, temperature sensor is provided in the cutter, the temperature sensor is connected with controller input terminal
It connects；The controller output end is connected with the switch unit between heating rod and power supply.
Further, the temperature sensor uses thermocouple, the thermocouple to pass through thermocouple signal line and control
Device input terminal is connected.
Further, the switch unit is switching transistor or relay.
With the above structure, using the special characteristics of diaphragm material, (its toughness can change the utility model under high temperature
Become etc.), in the case where not changing existing cutter operation principle, increase a heating function on cutter structure, that is, uses hot knife will be every
The principle of film fusing, can effectively reduce the abrasion of cutter, improve cutter and cut off effect, ensure the neat and consistent of diaphragm cut-out
Property.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model diaphragm hot knife device.
Fig. 2 is the utility model cutter internal thermocouples detects schematic diagram.
Fig. 3 is that schematic diagram is heated inside the utility model thermal conduction base.
In figure：1 is the heat-insulated pedestal of hot knife, and 2 be thermal conduction base, and 3 be cutter, and 4 be thermocouple, and 5 be thermocouple signal
Line, 6 be heating rod, and 7 be heating rod power cord
Specific implementation mode
As shown in figures 1 and 3, the diaphragm hot knife device of the utility model, including cutter 3, the cutter 3 are fixed on heat
On the heat-insulated pedestal of cutter 1, it is fixed with the thermal conduction base 2 being in contact with cutter on the heat-insulated pedestal of the hot knife 1, the heat passes
It leads and is provided with heating rod 6 in pedestal 2, the heating rod 6 is connected by heating rod power cord 7 with power supply.
Further, temperature sensor is provided in the cutter, the temperature sensor is connected with controller input terminal
It connects.In present embodiment, the temperature sensor uses thermocouple 4, the thermocouple 4 to pass through thermocouple signal line 5 and control
Device input terminal is connected.The controller output end is connected with the switch unit between heating rod and power supply, and the switch is single
Member uses switching transistor or relay, can control the break-make that thermocouple 4 connects power supply by controller in this way.
The operation principle of the utility model is as follows：As shown in Figure 1, installing heating rod 6, heating rod 6 on thermal conduction base 2
It is powered by heating rod power cord 7, converts electric energy to heat so that temperature is increased to the value of requirement, finally by heat transfer
Effect, heat can be transmitted to above cutter 3.On the head of cutter 3, there are one thermocouples 4 for installation, for detecting the practical temperature of cutter
Signal is fed back to controller, controller controls at the power switch of heating rod 6, stops by degree when cutter temperature reaches setting value
It only powers, stops heating at this time, i.e., realize the closed-loop control of cutter steady temperature by thermocouple 4；Since cutter temperature increases,
It needs in same equipment other mechanisms to be isolated, so to process an adiabatic workpiece (hot knife heat-insulated pedestal 1), cutter is mounted on
Above, then by pedestal it is fixed on above equipment.As shown in Fig. 2, being embedded in the structural schematic diagram inside cutter for thermocouple, mainly
Close to cutter head, the temperature on cutter head is detected in real time；Show as shown in figure 3, being installed inside thermal conduction base 2 for heating rod
It is intended to, pedestal needs the material for selecting thermal conduction effect good.
Although the foregoing describe specific embodiment of the present utility model, those skilled in the art should manage
Solution, these are merely examples, various changes or modifications can be made to present embodiment, without departing from the original of the utility model
Reason and essence, the scope of protection of the utility model are only limited by the claims that follow.
