Description
Technical field
The utility model relates to cylindrical nickel-metal secondary battery field, particularly a kind of volume pin for cylindrical nickel-metal secondary battery.
Background technology
Usually, in the manufacturing process of battery, pole piece winding is one very important operation, and just, the position of negative plate and barrier film is opposing parallel, neatly, can not barrier film be exceeded, the distance of positive and negative lug and position can not deviation too large, otherwise, battery tray can be made to assemble inconsistent, battery seriously can be made to scrap.
In cylinder-type nickel-metal hydride battery is produced, battery positive/negative plate forms battery core by winding, and the quality of structure to the battery core of winding of volume pin has a great impact.Current cylinder-type nickel-metal hydride battery volume pin is one with the regular hexagon cylinder of corner angle, barrier film is around volume pin outer surface, and the corner angle of volume pin drive barrier film roll set, and roll set easily causes barrier film to skid, scratch barrier film, cause the direct contact short circuit of positive/negative plate, cause potential safety hazard.
Utility model content
The utility model proposes a kind of volume pin for cylindrical nickel-metal secondary battery, when solving regular hexagon cylinder roll set in prior art, corner angle drive barrier film roll set to scratch barrier film, cause the direct contact short circuit of positive/negative plate, cause the problem of potential safety hazard.
The technical solution of the utility model is achieved in that
The utility model discloses a kind of volume pin for cylindrical nickel-metal secondary battery, comprise the volume pin body of the Zheng Ji Pian ﹑ Ge Mo ﹑ negative plate that winding is placed successively, described volume pin body comprises two symmetrically arranged first semicylinders and the second semicylinder that separate, have banded space in the middle of two described semicylinders, the described Zheng Ji Pian ﹑ Ge Mo ﹑ negative plate placed successively is wound on the first semicylinder by described banded space.
Further, described banded space arranges light sensor, and the second described semicylinder is arranged on Mobile base, and described light sensor connects the driving mechanism of Mobile base.
Further, described driving mechanism has the controller be connected with light sensor, the motor control module be connected with controller and the motor be connected with described motor control module.
Further, described controller is comparator.
Implement a kind of volume pin for cylindrical nickel-metal secondary battery of the present utility model, there is following useful technique effect:
When being different from existing regular hexagon cylinder roll set in the art, corner angle drive barrier film roll set to scratch barrier film, cause the direct contact short circuit of positive/negative plate, cause the problem of potential safety hazard, volume needle set in the technical program has cylinder, can prevent the generation scratching barrier film, promotes electric core winding quality.

Fig. 2 is the volume pin for cylindrical nickel-metal secondary battery of the present utility model winding schematic diagram.
Fig. 3 is the left view of the volume pin for cylindrical nickel-metal secondary battery of the present utility model.
Fig. 4 is the sectional view of the volume pin for cylindrical nickel-metal secondary battery of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, existing volume pin schematic diagram in the art, volume pin 1 comprises volume pin body, and this volume pin body is hexagon, and the positive plate 11 ﹑ barrier film 12 ﹑ negative plate 13 placed successively is reeled by this hexagon.
Refer to Fig. 2, embodiment of the present utility model, a kind of volume pin for cylindrical nickel-metal secondary battery comprises the volume pin body 3 of the positive plate 21 ﹑ barrier film 22 ﹑ negative plate 23 that winding is placed successively, volume pin body 3 comprises two symmetrically arranged first semicylinder 31 and the second semicylinders 32 separated, have banded space 33 in the middle of two semicylinders, the positive plate 21 ﹑ barrier film 22 ﹑ negative plate 23 placed successively is wound on the first semicylinder 31 by banded space 33.
Adopt this structure, replace hexagon with round, the winding tape winding that the positive plate 21 ﹑ barrier film 22 ﹑ negative plate 23 placed successively is formed is more smooth, not easily punctures.
Further, during in order to prevent roll set, barrier film skids, during roll set, barrier film all has face to contact with two semicolumns, barrier film can be fixed well, prevent winding barrier film from skidding and scratching barrier film, banded space 33 can arrange light sensor, and the second semicylinder 32 is arranged on Mobile base, and light sensor connects the driving mechanism of Mobile base.Driving mechanism has the controller be connected with light sensor, the motor control module be connected with controller and the motor be connected with described motor control module.
Wherein, described controller is comparator.
When banded space 33, spacing is excessive, light sensor produces light sensitive effect, transmit a signal to controller, controller receives signal, and send the closely spaced instruction of contracting to motor control module, driven by motor second cylinder 32 is close to the first cylinder 31, thus reduce banded space 33, to make always there is stable and suitable spacing during barrier film roll set, in order to avoid spacing is excessive, barrier film is caused to skid.
Implement a kind of volume pin for cylindrical nickel-metal secondary battery of the present utility model, there is following useful technique effect:
When being different from existing regular hexagon cylinder roll set in the art, corner angle drive barrier film roll set to scratch barrier film, cause the direct contact short circuit of positive/negative plate, cause the problem of potential safety hazard, volume needle set in the technical program has cylinder, can prevent the generation scratching barrier film, promotes electric core winding quality.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
