At present, the electric core after battery manufacturing industry both domestic and external is finished battery winding all carries out the operation of through hole, described electric core by positive plate, negative plate, membrane coil around forming.Main electric core through hole mode has the manual through hole of semi-automatic production line and the automatic through hole of automatic production line at present.
But the through hole mode of automatic production line is the through hole that the mode that re-uses through hole pin heating after up-coiler coiling utmost point group is finished is carried out electric core utmost point group, the problem below this through hole mode has occurred in the large-scale production process of battery:
At first, the through hole pin that is used for through hole often need be adjusted, and makes the poor stability of electric core through hole; Secondly, the position, back is easy to generate variation on the conveyer belt because electric core is placed on, and electric core is carried out the through hole fraction defective height of through hole, and in addition, the electric core centre bore that through hole forms is not mellow and full, and the barrier film of centre bore rebounds easily, to the requirement height of through hole temperature and time.
The utility model content
In view of this; the purpose of this utility model provides a kind of processing unit (plant) of lithium ion battery cell through hole; its use is used to reel the volume pin of electric core as adding the heat through-hole pin, and convenience simple in structure no longer needs to use special through-hole structure; formed through hole good stability; the through hole fraction defective is low, and formed electric core centre bore is mellow and full and make barrier film not rebound, and has improved the quality of production of battery; can form the scale of industry, be of great practical significance.
For this reason, the utility model provides a kind of processing unit (plant) of lithium ion battery cell through hole, and around forming, this device is used to reel the volume pin 2 of electric core 1 as adding the heat through-hole pin to described electric core 1 by positive plate, negative plate, membrane coil.
Preferably, the described heat through-hole pin that adds is connected with the output shaft of a servomotor.
Preferably, described electric core 1 is clamped in the manipulator 3.
Preferably, the described heat through-hole pin that adds is a volume pin 2.
The technical scheme that is provided by above the utility model as seen; compared with prior art; the processing unit (plant) of a kind of lithium ion battery cell through hole that the utility model provides; its use is used to reel the volume pin of electric core as adding the heat through-hole pin; convenience simple in structure; no longer need to use special through-hole structure; formed through hole good stability; the through hole fraction defective is low; and formed electric core centre bore is mellow and full and make barrier film not rebound; improved the quality of production of battery, can form the scale of industry, be of great practical significance.

Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1 to Fig. 4, the utility model provides a kind of processing unit (plant) of lithium ion battery cell through hole, described electric core 1 by positive plate, negative plate, membrane coil around forming, this device be used to reel volume pin 2 of electric core 1 adds the heat through-hole pin as what be used for electric core through hole, described electric core 1 is clamped in the manipulator 3, and the described heat through-hole pin that adds is connected with the output shaft of a servomotor.
Need to prove that the volume pin 2 of the described electric core that is used to reel includes two volume pins.
In the utility model, described manipulator 3 can be for being used for the manipulator of electric core blanking.
On the specific implementation, referring to Fig. 3, the described heat through-hole pin that adds is preferably a volume pin 2, promptly can be just adds the heat through-hole pin with what a volume pin 2 was used as being used for through hole, certainly, on the specific implementation, also can be two and roll up pins.
For the utility model, in the concrete utilization, at positive plate, negative plate, barrier film is reeled through up-coiler behind the columniform electric core 1 of formation, referring to Fig. 2, by manipulator 3 electric core 1 is clamped, the two volume pins 2 of electric core 1 of will being used to then to reel are extracted one (referring to Fig. 3) out, drive that remaining root volume pin rotate a certain angle (for example being 180 degree) by servomotor then, for example shown in Fig. 3 arrow according to certain angle that turns clockwise, thereby carry out the through hole operation of electric core, finally finish the through hole (referring to shown in Figure 4) of electric core, so the reel volume pin of electric core of the utility model utilization is finished the through hole of electric core, saved original electric core through hole mechanism, winding apparatus is oversimplified, saved production cost, and through hole is mellow and full, barrier film can not rebound, and has improved the total quality of electric core greatly.
In sum; compared with prior art, the utility model provides a kind of processing unit (plant) of lithium ion battery cell through hole, and its use is used to reel the volume pin of electric core as adding the heat through-hole pin; convenience simple in structure; no longer need to use special through-hole structure, formed through hole good stability, the through hole fraction defective is low; and formed electric core centre bore is mellow and full and make barrier film not rebound; improved the quality of production of battery, can form the scale of industry, be of great practical significance.
