Description
Technical field
The utility model relates to a kind of device that battery pole piece is produced that is used for, particularly with the device at pole piece circle of contact angle.
Background technology
At present because the high request of battery capacity; Increased the quality of both positive and negative polarity active material, barrier film etc.; Make that the inside battery space is narrower and small, the extruding between pole piece and the barrier film is more obvious, the expansion of active material volume when adding battery charging and discharging makes battery because of pole piece burr, particularly pole piece afterbody burr generation internal short-circuit; Cause battery failure, even blast.Experiment is found, need make fillet to the wedge angle burr of pole piece afterbody and handle, and can well address this problem, but suitable device is not arranged at present.
The utility model content
The utility model aims to provide a kind ofly makes the device that fillet is handled to pole piece, through excision afterbody wedge angle burr, eliminates the short circuit of battery afterbody wedge angle burr and threatens.
The utility model scheme is following:
A kind of device that is used for pole piece circle of contact angle comprises stamping machine, at least one last clip, at least two following clips, at least 2 location-plate parts; Said upward clip parts are the platform of square; Have a radius in the center of platform and be 5～90 millimeters the hollow cylinder mouth that runs through square from top to bottom fully; This cylinder mouth is connected with stamping machine; Have the hollow circular arc body that runs through square from top to bottom fully (being that a certain short transverse of square has formed cambered inwards circular arc body shape) of identical certain radius, identical specific arc at any a jiao or a plurality of angle of square; Said specific arc is 90 ± 3 degree, and said certain radius is 2～8 millimeters; Following clip is the platform of cuboid; Open the hollow cylinder mouth that runs through cuboid from top to bottom fully of 2～150 millimeters of one or more radiuses in the centre of platform; It is fixing that fixture will descend clip to be connected with the work top of stamping machine through the cylinder mouth; One jiao of this cuboid or a plurality of angle are polished into the Filled Arc body; All the hollow circular arc body radius with last clip is identical with radian for the radius and the radian of (two angles that are the sustained height direction of cuboid upper and lower surfaces are polished into circular arc respectively, form the circular arc body shape toward evagination) this Filled Arc body; Location-plate is positioned over and the tangent position of following clip Filled Arc body; The platform of upper and lower clip is parallel, and location-plate meets at right angles each other.
If adopt manual mode in the practice, then preferred version is preferred 1 of a last clip number of components, preferred 2 of following clip parts, 2 of location-plates, 1 hand punch.
If adopt pneumatic mode in the practice, preferred version is preferred 4 and be arranged side by side of a last clip number of components, preferred 2 of following clip parts, and 3 of location-plates, 1 pneumatic stamping machine, and also include inductor in the device.
After adopting the device of the utility model; Can the wedge angle of the four direction of pole piece be repaiied and be cut into arcuation; Thereby can make pole piece be difficult for scratching barrier film, when battery is made the cover box hat in the flow process to the scratch of barrier film threaten reduce to minimum, thereby reduce of the influence of afterbody wedge angle burr to internal short-circuit of battery.

Embodiment
Embodiment is just in order to explain a kind of implementation of the utility model, not as the restricted explanation to the utility model protection range.
Manual type pole piece round cornering machine, sketch map such as Fig. 1.The stamping machine 1, one that include manual type are gone up 2, following clips 3 of clip and two location-plates 4.
Fig. 2 is seen in the structural representation of last clip parts 2; Use the quenching high-speed steel; Be the length of side and be 15.5 millimeters square platform; Have a radius in the center of platform and be 7.6 millimeters the hollow cylinder mouth 21 that runs through square from top to bottom fully; This cylinder mouth is connected with stamping machine 1, and to have radius be that 3.5 millimeters, radian are the hollow circular arc body 22 that runs through square from top to bottom fully (being that a certain short transverse of square has formed cambered inwards circular arc body shape) of 90 degree at square any one jiao.
Following clip 3 structural representations are seen Fig. 3; Use the quenching high-speed steel; The platform length that is cuboid is of a size of 51 millimeters, 51 millimeters, 27 millimeters, opens the hollow cylinder mouth 31 that runs through cuboid from top to bottom fully of 7.5 millimeters of two radiuses in the middle symmetry of platform, and it is fixing that fixture will descend clip to be connected with the work top of stamping machine 1 through the cylinder mouth; One jiao with this cuboid is polished into Filled Arc body 32; (two angles that are the sustained height direction of cuboid upper and lower surfaces are polished into circular arc respectively, form the circular arc body shape toward evagination), all the hollow circular arc body radius with last clip is identical with radian with radian for the radius of this Filled Arc body.
The placement of each parts signal sees that Fig. 4, location-plate are positioned over and the tangent position of following clip 3 Filled Arc bodies 32; Last clip 2, the platform of clip 3 is parallel down, and two location-plates 4 meet at right angles each other.
During use; Get a slice positive plate or negative plate and place on following clip 3 platforms of level, press down the pressure arm of manual type stamping machine 1, become the last clip of 90 degree arcs to downcut thereupon along location-plate; Under the effect of shear force up and down, the pole piece wedge angle is excised; Repetitive operation can make pole piece become about 90 degree circular arcs in 90 degree right angles originally, thereby eliminate the scratch threat of afterbody wedge angle burr to battery diaphragm four wedge angles difference circle of contact angles of pole piece.
Pneumatic type pole piece round cornering machine adopts the stamping machine of pneumatic type, the last clip that four are arranged side by side, two following clip and three location-plates side by side, and inductor.
Upper and lower clip 6 is basic identical with the upper and lower clip structure and the size of manual type pole piece round cornering machine, and three location-plates meet at right angles in twos.
During use; Get two positive plates or negative plate parallel the placing on the following clip platform of level along the location-plate both sides respectively; Trigger inductor, side by side, become 90 degree arcs four go up clip and downcut thereupon, under the effect of shear force up and down, the pole piece wedge angle is excised; Make pole piece become 90 degree circular arcs in 90 degree right angles originally, repetitive operation can be to four wedge angles difference circle of contact angles of pole piece.
