SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can solve weak sealing, electric core corrosion problem's that leads to because of remaining electrolyte when electric core exhaust heat-seal supplementary tool.
In order to achieve the above object, the present invention adopts the following technical solutions:
Supplementary tool of heat-seal includes: the jig comprises a jig body, a positioning part and a positioning part, wherein the jig body is provided with an air bag placing part for placing an air bag of a battery core, and the air bag placing part is arranged in a downward inclination manner; the air bag pressing plate is positioned above the jig body and can reciprocate along the vertical direction, the air bag pressing plate is provided with a pressing part corresponding to the air bag placing part, and the pressing surface of the pressing part is parallel to the air bag placing part.
Further, the surface of the air bag placing part, which is in contact with the air bag, is provided with a knurled pattern.
Furthermore, the pressing surface of the pressing part is provided with a reticulate pattern knurl.
The surface of the air bag placing part for placing the air bag and/or the pressing surface of the pressing part are/is provided with the reticulate knurls, so that the air bag can be conveniently exhausted outwards and electrolyte can be conveniently discharged.
Further, the inclination angle of the air bag placing portion is 45 °.
According to the technical scheme, the utility model discloses a heat-seal auxiliary fixture sets up the plane of placing electric core air pocket to the downward sloping, rather than be the horizontal plane with the face of placing of electric core the same, make the air pocket of placing on it also be the downward sloping state, electrolyte in the air pocket flows down naturally under the action of gravity from this, puncture the air pocket after, electrolyte can not flow back to waiting to seal the district, and can accelerate electrolyte outwards to flow out, the weak problem of sealing that leads to because electrolyte remains too much or the influence of backward flow when having solved the heat-seal in the exhaust process; meanwhile, the air bag placing part is of a downward-inclined structure, so that the air bag and the battery cell body are not on the same plane, the phenomenon that the surface of the battery cell is corroded due to splashing of electrolyte during exhaust can be avoided, the product yield is improved, and the product quality is guaranteed.
drawings
In order to illustrate the embodiments of the present invention more clearly, the drawings that are needed in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and that other drawings can be obtained by those skilled in the art without inventive effort.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
Fig. 2 is a side view of an embodiment of the present invention.
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, wherein for convenience of illustration, the drawings showing the structure of the device are not to scale and are partially enlarged, and the drawings are only examples, which should not limit the scope of the invention. It should be noted that the drawings are in simplified form and are not to precise scale, which is only used for the purpose of facilitating and clearly assisting in the description of the embodiments of the present invention.
Referring to fig. 1 and 2, the heat-sealing auxiliary fixture of the present embodiment includes a fixture body 1 and an air bag pressing plate 2, the fixture body 1 is used for placing an air bag of a battery cell, and is equivalent to a liquid leakage groove, and the air bag pressing plate 2 is used for pressing the air bag located on the fixture body 1. The air bag pressing plate 2 is located above the jig body 1 and can move up and down along the vertical direction, so that an air bag on the jig body 1 is pressed. The jig body 1 has a downwardly inclined air bag placing portion 1a, and more specifically, the inclined angle of the air bag placing portion 1a may be 45 °. Preferably, a knurled pattern is formed on the surface of the air bag mounting portion 1a that contacts the air bag. The airbag cover 2 has a pressing portion 2a for pressing the airbag, a pressing surface of the pressing portion 2a is provided corresponding to the airbag mounting portion 1a, and a pressing surface of the pressing portion 2a is parallel to the airbag mounting portion 1a, that is, an inclination angle of the pressing surface is the same as an inclination angle of the airbag mounting portion 1 a. When the airbag cover 2 is pressed down, the pressing portion 2a engages with the airbag mounting portion 1a to press the airbag positioned on the airbag mounting portion 1 a. Preferably, the pressing surface of the pressing portion 2a may be knurled. The jig main body 1 of this embodiment is made of SUS304, and the air bag presser plate 2 is made of AL 6061.
