Referring to FIG. 7 , in the first packaging step, the secondary batteries 2 filled in the alignment tray 10 are inserted into the inner packaging material 20 in an aligned state using the inner packaging machine 200 and packed. Here, the inner packaging machine 200 includes a second conveying member 210, a packaging material conveying member 220, and a packaging member 230.

That is, in the primary packaging step, the alignment tray 10 transferred from the aligner 100 is transferred to a set position by using the second transfer member 210 . At the same time, the inner packaging material 20 is transferred to a position corresponding to the alignment tray 10 by using the packaging material transfer member 220 . Next, using the packaging member 230, one line or all two lines of the secondary batteries 2 filled in the alignment tray 10 are adsorbed, and then the aligned secondary batteries 2 are inserted into the packaging member 230 as they are. wrap it up

When the primary packaging step is completed, the second transfer member 210 transports the inner packaging material 20 into which the secondary battery 2 is inserted to the protection step. At this time, while the inner packing material 20 transported by the second transfer member 210 passes through the quantity inspection step, the quantity of the secondary batteries 2 inserted into the inner packing material 20 is inspected.

Quantity inspection step

Referring to FIG. 8 , the quantity inspection step is for inspecting the quantity of the secondary batteries 2 inserted into the inner packing material 20 using the quantity tester 300 . Here, a laser is irradiated on the inner packaging material 20 through a non-contact laser inspection machine, which is a quantity inspection machine 300, to calculate the quantity of the secondary batteries 2 inserted into the inner packing material 20, and to compare the calculated quantity with the input quantity. If they are the same, it is determined as normal, and if they are different, it is determined as defective.

protection level

Referring to FIG. 9, the protection step is to cover the secondary battery 2 by covering the upper part of the secondary battery 2 inserted into the inner packaging material 20 using the cover tray inserter 400 to cover the secondary battery 2 Keep them aligned and secure. Here, the cover tray inserter 400 includes a third transfer member 410 and a cover tray insertion member 420 .

That is, in the protection step, the inner packing material 20 that has passed the quantity inspection step is transferred to the setting position by using the third transfer member 410 . Next, the cover tray 30 is adsorbed using the cover tray loading member 420, moved to the top of the inner packaging material 20, and then dropped. Then, the cover tray 30 is disposed on the inner packaging material 20 and at the same time the secondary battery 2 is inserted into the insertion groove of the cover tray 30 . That is, the cover tray 30 is covered on the upper part of the secondary battery 2, and as a result, the secondary battery 2 can be fixed and protected in an aligned state.

Meanwhile, when the protection step is completed, the third transfer member 410 transfers the inner packaging material 20 including the cover tray 30 to the second packaging step.

2nd packaging step

Referring to FIGS. 10 and 11A to 11C , the secondary packaging step is to assemble a packaging box to wrap the outside of the inner packaging material 20 including the cover tray 30 using an external packaging machine 500. That is, the secondary packaging step assembles the packaging box 40 for packaging the inner packaging material by folding the packaging paper 40a. Here, the external packaging machine 500 includes a fourth conveying member 510, a wrapping paper conveying member 520, and an assembly member 530.

That is, in the secondary packaging step, the packaging paper is placed on the assembly member 530 using the packaging paper transfer member 520 . Next, the inner packaging material 20 transferred from the protection step is placed on the bottom surface 41 of the wrapping paper 40a disposed on the assembly member 530 by using the fourth transfer member 510 . Next, the side surface of the packaging paper 40a is folded in the direction of the inner packaging material 20 using the assembly member 530, and the upper surface of the inner packaging material 20 is closed by pressing the cover surface 43 of the packaging paper. Then, the packaging box 40 for packaging the inner packaging material 20 is assembled.

closing stage

Referring to FIGS. 12 to 17, when the secondary packaging step is completed, the main surface of the packaging box 40 including the inner packaging material 20 is taped with tape 4, and the label 5 is printed Then, the packing box 40 is moved to a set location and loaded or stored.

That is, in the finishing step, the main surface of the packaging box 40 containing the inner packaging material 20 transferred from the secondary packaging step is taped and sealed using the taping machine 600, and the label printing machine 700 is used to print a label for identifying the secondary battery 2 on the side of the packing box 40 containing the inner packing material 20, and using the stacker 800 to pack the packing box 40 containing the inner packing material 20 ) is moved to the set place and loaded or stored.

Meanwhile, after the primary packaging step, a desiccant insertion step of inserting a desiccant into the inner packaging material 20 may be further included. That is, in the step of inserting the desiccant, the desiccant is injected into the inner packaging material 20 transferred from the quantity tester 300 to the cover tray inserting member 420 using the desiccant inserter.
