The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The noun explains:
stacking: and stacking the battery cores one by one into a specified state by a certain process method.
Entering a mold: and (4) installing and assembling the stacked battery cell modules into a specified module shell through certain tooling equipment.
An automatic stacking and mold-entering method for battery cells is disclosed, as shown in fig. 1, and includes: the electric core horizontal bar is by left to right/by right to left or vertical bar by last to down/by carrying out electric core by lower to last and piling up, fixes through colloid or colloid bubble cotton between the electric core, guarantees that certain size, tolerance stack up appointed quantity after, compresses tightly and keeps certain form with electric core group by equipment frock, satisfies the size of the requirement of going into the mould.
In the first specific embodiment, positioning is performed by taking a plane as a reference, all the battery cells on a platform are positioned by the height of the battery cell from the bottom edge of the battery cell, and then the battery cell is moved left and right to be positioned until a specified position is reached, so that the height direction and the left and right direction of the battery cell both meet the tolerance requirement of stacking.
In the second specific embodiment, the battery cell is positioned by the center of the battery cell in the stacking process, and the position of the battery cell before stacking is positioned from left to right and then positioned in the height direction, so that the height direction and the left and right directions of the battery cell meet the tolerance requirement of stacking. The electric cores are vertically stacked from left to right.
And (3) putting the battery cell into a mold: after the electric core group is arranged well by certain dimensional tolerance, keep certain clamp force with the electric core group, guarantee certain position precision with module box casing, from top to bottom in impressing the electric core group in the casing or from bottom to top impress the electric core group in the casing, become compact state with the casing behind the cotton or colloid resilience back between the electric core, and the electric core group can exert certain extrusion force to the casing, the position of electric core casing restriction electric core, prevent that the loose drunkenness of electric core from leading to the position degree variation of electric core group and casing.
After the combination is arranged according to certain required size to electric core, place on the platform, guarantee certain position accuracy with module box casing, the module casing is by last from down fall-down pressure into electric core group or from bottom to top malleation advance electric core group, be the state that is compressed tightly before the shell is gone into to electric core, the inflation force that the cotton or colloid resilience of bubble between the electric core was kick-backed after the electric core group was impressed to the casing is compact state with the casing, the position of electric core casing restriction electric core, prevent that the drunkenness of casing from leading to the positional deviation of electric core group and casing.
Battery cell detection: and detecting the size of the battery cell group through the battery cell measuring equipment. The cell measuring equipment is common equipment in the field.
The electric core group clamping plate 1 clamps one or more groups of electric core groups in a fixed size and fixed pressure mode (adjusting equipment parameters according to actual requirements) after any one of the size and the pressure is reached by taking the electric core group clamping plate 1, the electric core group upper pressing plate 2 and the electric core group lower supporting plate 3 as a guide mechanical clamp from the stacking table; if the size is not enough, the pressure is NG first, and the device gives an alarm to prompt for manual treatment.
The battery core clamping prevents that electric core from forming the recessed problem in battery core group center because of the influence of gravity when removing into the module, and electric core measuring equipment needs to increase two battery core group bottom plate crossbeam structures 4 in electric core bottom position, prevents that battery core group warp because of the influence of gravity. After the electric core group is sent to the set position, the two electric core group lower supporting plate beam structures are drawn away.
The process adopts a mode of stacking the battery cores without the Block frame and integrally molding the battery cores, reduces the Block frame, and reduces the process steps and the cost of module components for module production.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
