Because the electric core can not completely ensure that the size and the design standard are consistent after the electric core is wound, radial size deviation can be inevitably generated, and the situation that the outer diameter sizes of all parts of one electric core are different can also be possibly generated, after the electric core is pushed into the electric core positioning and guiding mechanism by the electric core shell-entering mechanism, the whole outer diameter of the electric core can be reduced to be within a preset range while guiding is realized. After the outer diameter of the battery cell is reduced, the battery cell can better enter the shell, the situation of clamping is avoided, and the battery cell is prevented from being damaged.
The step of reducing the outer diameter of the battery cell to be smaller than the inner diameter of the battery shell means that: the cell positioning and guiding mechanism is provided with a plurality of guiding blocks for contacting the cell, the guiding blocks are connected with elastic pieces, the elastic force provided by the guiding blocks through the elastic pieces uniformly applies force to the cell from the circumferential direction, so that the outer diameter of the cell is reduced, the cell moves along with the pushing of the cell into the shell mechanism while reducing the outer diameter from one end of the cell, and the cell gradually enters the battery shell while reducing the outer diameter.
The method for inserting the cylindrical battery cell into the shell comprises the following specific steps:
step one, providing a battery shell and a battery core;
step two, placing the battery shell on a battery conveying line, and placing the battery cell on a bearing seat 32 of the battery cell bearing mechanism 3;
step three, the battery shell is conveyed to a position corresponding to the battery core by the battery conveying line, and the battery shell is held by the shell positioning mechanism from the circumferential direction of the battery to be positioned;
step four, the battery cell shell entering mechanism pushes the battery cell to move towards the battery cell positioning guide mechanism, and when the battery cell enters the range of the battery cell positioning guide mechanism, the battery cell positioning guide mechanism holds the battery cell;
fifthly, limiting the end part of the battery shell by the shell limiting mechanism, and continuously pushing the battery core to move by the battery core shell entering mechanism, so that the battery core enters the battery shell;
step six, after the battery core completely enters the shell, resetting the battery core positioning guide mechanism, resetting the battery core shell entering mechanism, resetting the shell limiting mechanism and resetting the shell positioning mechanism, and conveying the assembled battery away by the battery conveying line;
in the fourth step, when the battery core enters the range of the battery core positioning and guiding mechanism, the battery core shell entering mechanism pauses pushing the battery core, and after the battery core positioning and guiding mechanism holds the battery core, the battery core shell entering mechanism continues pushing the battery core.
According to the invention, under the cooperation of the battery conveying line 1, the battery core positioning and guiding mechanism 2, the battery core bearing mechanism 3, the battery core shell-entering mechanism 4, the shell positioning mechanism 6 and the shell limiting mechanism 5, the shell can be positioned and pushed into the shell, and products are automatically sent away after shell entering is completed, so that the whole shell-entering operation is automated, manual participation is not needed, the operation efficiency is improved, and meanwhile, the battery core damage caused by human factors can be avoided. The battery cell positioning and guiding mechanism 2 can guide and position the battery cell, so that the movement of the battery cell is stable and the positioning is accurate, and the speed of the shell-entering operation is ensured. The electric core positioning and guiding mechanism 2 can reduce the outer diameter of the electric core in the guiding process, and ensures that the electric core can completely enter the shell under the condition that the shell deforms, so that the assembly effect is ensured, the electric core is prevented from being damaged in the assembly process, and the yield is ensured.
