Description
Technical field
The present invention relates to lithium battery electric core manufacture field, the loading and unloading hot-press method and dress of especially a kind of battery core hot press
It sets.
Background technique
In the manufacturing process of lithium battery, when battery core needs immediately to carry out at hot pressing battery core after winding or lamination process
Reason, i.e. battery core apply certain face pressure to battery core body and are kept for a period of time, become battery core more in the state of heated
It is closely knit.Battery core after hot pressing, pole piece and diaphragm fitting are closer, if in the case that diaphragm or pole piece have gluing, warp
Battery core pole piece and diaphragm after crossing hot pressing can stick together, so that can effectively prevent in subsequent transportation and circular flow
The fold of battery core pole piece and dislocation and diaphragm between diaphragm, greatly improves the safety of lithium battery.
It needs to be heated and pressurizeed battery core by the heating platen of hot pressing mechanism in hot pressing, when hot pressing terminates
It needs to take out battery core from hot pressing mechanism again afterwards and is transported to lower section processing apparatus.But due in hot pressing, high temperature and
High pressure effect is likely to result in battery core and heating platen is sticky in together, can not remove from heating platen so as to cause battery core.Therefore,
It needs to optimize hot pressing mechanism to facilitate battery core blanking after hot pressing, solves the problems, such as that battery core and the viscous of heating platen stick.
In view of the above-mentioned problems, current cutting design scheme is mainly by carrying out anti-stick coating surface treatment to heating plate
It is sticked to avoid battery core and the viscous of heating plate, the blanking of battery core is then carried out by way of mechanical clamping or negative pressure absorbing.
Scheme one：Heating plate after anti-stick coating is handled, battery core and heating plate can be made not viscous in hot pressing or
Person glues viscous force and is effectively reduced, and after the completion of battery core hot pressing, clamping battery core by mechanical gripper makes battery core and heating plate be detached from completion
Blanking (referring in particular to Fig. 1).
The program is disadvantageous in that：
Hot pressing mechanism is opened after hot pressing is complete, and upper hot pressboard can be separated with battery core, but battery core can be sticky in lower hot pressing board
Together, if picking up battery core in such a way that manipulator grabs battery core side, mechanical gripper closure clamps battery core and mentions then up
Battery core and lower hot pressing board separation are played, the upward extraction force of manipulator must overcome the viscous of the gravity of battery core, battery core and lower hot pressing board
Viscous force；Even if battery core is not viscous glutinous with lower hot pressing board, the upward extraction force of manipulator also must overcome the gravity of battery core, however mostly
Number power lithium cell electric core weight is near or above 1kg, and in order to overcome these resistances, the clamping force of mechanical gripper will lead to battery core
Lateral force deformation is generated, battery core appearance damage or pole piece edge is caused to lose powder, this safety and quality for lithium battery
It is fatal influence.
Scheme two：Heating plate after anti-stick coating is handled, battery core and heating plate can be made not viscous in hot pressing or
Person glues viscous force and is effectively reduced, and after the completion of battery core hot pressing, is sucked up battery core by suction nozzle, is detached from battery core and heating plate and completes
Blanking (referring in particular to Fig. 2).
Unlike scheme one, battery core upper surface is sucked by sucker in the program, extracts battery core then up, makes battery core
It is detached from lower hot pressing board and completes blanking.But sucker power needs to overcome battery core gravity that can just lift battery core, and sucker active force is mainly made
It being pullled on the diaphragm of battery core upper surface, will lead to generate between diaphragm and battery core pole piece, leading to diaphragm and pole piece tacky state
Larger change occurs.Moreover, once diaphragm is pullled the safety and product even if faint breakage occurs, for lithium battery by sucker power
Matter is also fatal influence.
In conclusion traditional scheme one and scheme two is no longer satisfied the growing product safety of lithium battery and product
