Then, the carrying device 20 stacks the new middle package cover 102 on the middle package cover 102 filled with the battery cells, and carries the battery cells positioned by the battery cell positioning device 30 to each battery cell accommodating groove a on the upper side of the new middle package cover 102, so as to stack the plurality of middle package covers 102 to the designated height in sequence according to the above steps. So, adopt the manual work to carry out the pile up neatly packing of electric core among the prior art and compare, the utility model discloses a pile up neatly packing of electric core can be accomplished to electric core baling equipment, has improved degree of automation, is favorable to improving the production efficiency of electric core.

Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the battery cell packaging apparatus further includes a cover-in-package feeding device 40, where the cover-in-package feeding device 40 is used to provide a cover-in-package 102. The carrying device 20 is used for stacking the pack middle lids 102 supplied from the pack middle lid supply device 40 one by one onto the pack bottom lid 101.

In some embodiments, the cover-in-package feeding device 40 includes a material frame 41, a first lifting frame 42, and a feeding positioning mechanism. The first lifting frame 42 is disposed in the material frame 41 and is used for supporting a plurality of middle packing covers 102 stacked in the material frame 41. The feeding positioning mechanism is arranged on the top of the material frame 41 and used for positioning the cover 102 in the package entering the feeding positioning mechanism. The first lifting frame 42 is lifted (i.e. moved in the vertical direction) relative to the material frame 41 to lift the plurality of middle package covers 102 stacked on the first lifting frame 42. The first lifting frame 42 can drive the covers 102 stacked in the plurality of packages of the first lifting frame 42 to enter the feeding positioning mechanism one by one in the lifting process, so that the feeding positioning mechanism can position the covers 102 in the packages positioned at the top among the plurality of packages 102.

When the process of stacking and packaging the battery cells is performed, after the cover 102 positioned in the package of the feeding positioning mechanism is carried away by the carrying device 20, the first lifting frame 42 is lifted by a certain height, so that the cover 102 in the package positioned at the top enters the feeding positioning mechanism, and is positioned by the feeding positioning mechanism to be carried by the carrying device 20. It should be noted that the cover feeding device 40 further includes a lifting module 44, and the lifting module 44 is configured to drive the first lifting frame 42 to move (i.e., lift) in a vertical direction relative to the material frame 41. The lifting module 44 may be implemented by a conventional lifting module, and therefore will not be described herein.

Specifically, in the embodiment, the feeding positioning mechanism includes a first positioning block 431, a first positioning driving member 432, a second positioning block 433, and a second positioning driving member 434. The first positioning driving member 432 is installed at one side of the material frame 41 in a first direction perpendicular to the vertical direction, and the first positioning block 431 is connected to a driving end of the first positioning driving member 432 so as to be driven by the first positioning driving member 432 to extend into or withdraw from the material frame 41 along the first direction.

Thus, when the top middle package cover 102 needs to be positioned, the first positioning driving member 432 drives the first positioning block 431 to extend into the material frame 41, so as to push the middle package cover 102 along the first direction, and further, the first positioning block 431 and the material frame 41 are utilized to position the middle package cover 102 in the first direction; meanwhile, the second positioning driving element 434 drives the second positioning block 433 to extend into the material frame 41, so as to push the middle package cover 102 along the second direction, and further, the second positioning block 433 and the material frame 41 are utilized to position the middle package cover 102 in the second direction. When the carrying device 20 picks up the cover 102 in the package positioned by the feeding positioning mechanism, the first positioning driving member 432 drives the first positioning block 431 to withdraw from the material frame 41, so that the first positioning block 431 is separated from the cover 102 in the package, namely, the positioning of the cover 102 in the package in the first direction is released; meanwhile, the second positioning driving element 434 drives the second positioning block 433 to withdraw from the material frame 41, so that the second positioning block 433 is separated from the middle package cover 102, that is, the middle package cover 102 is released from being positioned in the second direction. Alternatively, the first positioning driver 432 may be a cylinder. The second positioning drive 434 may be a pneumatic cylinder.

In one embodiment, the lid feeder 40 further comprises a mounting bracket 45 and a translation drive mechanism. The material frame 41 is movably connected to the mounting frame 45.

The movement of the frame 41 relative to the mounting frame 45 includes a loading position for loading the cover 102 in the package and a feeding position for supplying the cover 102 in the package to the carrier device 20. In this way, when all of the lids 102 in the package in the frame 41 are carried away by the carrier device 20, the translational drive mechanism drives the frame 41 to move from the supply position to the loading position, so that the frame 41 is filled with the lids 102 in the package. The translational drive mechanism then drives the material frame 41 from the loading position to the feeding position so as to provide the handling device 20 with the in-package lids 102. Alternatively, the material frame 41 moves in the horizontal direction with respect to the mounting frame 45.

More specifically, the translational drive mechanism includes a translational drive element 461, a drive wheel, a driven wheel, and a drive belt 462. The translation driving member 461 is mounted on the mounting bracket 45, and the driving wheel is mounted on the output shaft of the translation driving member 461. The driven wheel is mounted on the mounting frame 45 and is arranged at intervals with the driving wheel along the moving direction of the material frame 41. The driving belt 462 is sleeved between the driving wheel and the driven wheel to move forward between the driving wheel and the driven wheel in sequence under the driving of the driving wheel. The driving belt 462 is connected with the material frame 41 through the connecting block 463 to drive the material frame 41 to move relative to the mounting frame 45, so that the material frame 41 can move back and forth between the loading position and the feeding position. Alternatively, the translation drive 461 may be a motor.

Further, a translation slide rail 451 is arranged on the mounting frame 45, a translation slider 452 is arranged on the material frame 41, and the translation slider 452 is slidably connected to the translation slide rail 451, so that the material frame 41 can move relative to the mounting frame 45.

The fool-proof driving member 471 is disposed on the material frame 41, and the fool-proof block 472 is connected to an output end of the fool-proof driving member 471, so as to be driven by the fool-proof driving member 471 to enter or exit the material frame 41. Thus, when the material frame 41 moves to the loading position, the fool-proof driving member 471 drives the fool-proof block 472 to extend into the material frame 41, and when the orientation of the middle package cover 102 is correct, the fool-proof block 472 matches with the fool-proof chamfer of the middle package cover 102, and at this time, the middle package cover 102 can be smoothly loaded into the material frame 41; when the orientation of the lid 102 in the package is wrong, the fool-proof block 472 cannot match the fool-proof chamfer of the lid 102 in the package, and at this time, the lid 102 in the package cannot be loaded into the material frame 41. When the package middle cover 102 is filled with the material frame 41, the fool-proof driving member 471 drives the fool-proof block 472 to exit the material frame 41, thereby avoiding interfering with the feeding positioning mechanism to position the package middle cover 102. Alternatively, the fool-proof actuation member 471 may be a pneumatic cylinder.

Referring to fig. 4 and 5, in an embodiment of the present invention, the battery cell positioning device 30 includes a bottom frame 31, a conveying mechanism 32, and a clamping mechanism.

The first clamping block 332 and the second clamping block 333 are arranged along a fourth direction perpendicular to the third direction, and both at least partially extend out of the conveying surface, so that the battery cell conveyed between the first clamping block 332 and the second clamping block 333 is clamped or released under the driving of the clamping driving piece 331. In this way, the clamping driving member 331 is used to drive the first clamping block 332 and the second clamping block 333 to clamp the battery cell therebetween, so as to position the battery cell. After the handling device 20 picks up the battery cell clamped by the first clamping block 332 and the second clamping block 333, the clamping driving member 331 drives the first clamping block 332 and the second clamping block 333 to release the battery cell, so that the handling device 20 can smoothly carry the battery cell away. Alternatively, the clamp drive 331 may be a jaw cylinder.

In a specific embodiment, the first clamping blocks 332 include a plurality of first clamping blocks 332 arranged along the third direction, the second clamping blocks 333 also include a plurality of second clamping blocks 333 arranged along the third direction. Thus, when the conveying mechanism 32 conveys the battery cell to a position between the first clamping blocks 332 and the second clamping blocks 333 along the third direction on the conveying surface, the clamping driving piece 331 drives the first clamping blocks 332 and the second clamping blocks 333 to clamp the battery cell together, so that the battery cell can be positioned better, and the positioning accuracy is improved. It should be noted that, in one embodiment, each clamping mechanism includes only one clamping driving member 331, each first clamping block 332 is mounted at the first driving end of the clamping driving member 331, and each second clamping block 333 is mounted at the second driving end of the clamping driving member 331. Of course, in other embodiments, each clamping mechanism may also include a plurality of clamping drivers 331, each clamping driver 331 having a first clamping block 332 mounted at a first driving end thereof, and each clamping driver 331 having a second clamping block 333 mounted at a second driving end thereof.

Further, the gripping mechanism includes a plurality of gripping mechanisms, and the plurality of gripping mechanisms are arranged in the fourth direction. The first clamping blocks 332 of one clamping mechanism and the second clamping blocks 333 of the other clamping mechanism of every two adjacent clamping mechanisms are alternately arranged along the third direction, so that the distance between the electric cores clamped by the clamping mechanisms is reduced, the mounting space is saved, and the distance between the electric cores is matched with the conveying device 20 and the distance between the electric core accommodating grooves a on the package bottom cover 101 and the package middle cover 102.

Further, the position of the clamp drive 331 of each clamp mechanism in the fourth direction relative to the chassis 31 is adjustable. Therefore, the positions of the battery cells clamped by the clamping mechanisms in the fourth direction can be adjusted by adjusting the positions of the clamping driving pieces 331 of the clamping mechanisms in the fourth direction, so that the positioning accuracy of the battery cells is improved on one hand, and the compatibility of the battery cell packaging equipment is improved in order to adapt to the battery cells with different specifications on the other hand. More specifically, each clamping mechanism further includes a mounting seat 334, an adjusting seat 335 and an adjusting member 336, the mounting seat 334 is movably connected to the chassis 31 along the fourth direction, and the clamping driving member 331 is fixedly connected to the mounting seat 334.
