In this embodiment, these rails 370 are provided separately as separate members such as metal, and are illustrated as being manufactured in an insert injection manner together with the outer frame 310.

The rail 370 is fixed in a state in which the flat shape of the bottom surface of the outer frame 370 is not damaged by insert injection. That is, when the integrated battery mounting portion 220 is directly coupled to the outer frame 210 using the bolts 290 or the like in the prior art of FIG. 2, Grooves for fastening had to be machined and these grooves or bolts 290 formed a step on the roller path line to cause a transverse impact between the conveyor roller and the tray 20 to cause damage to the tray or the battery itself, Since the battery mounting part composed of the plurality of main cassettes 320 and 322 is mounted on the rail part 370 in the present invention as shown in FIG. 5 (b) 312), so that this problem does not occur.

The rail 370 serves as an element for mounting a plurality of main cassettes 320 and adjusting the spacing between the plurality of main cassettes 320 and 322 mounted thereon. Specifically, the plurality of main cassettes 320 (322) are slidably fixed to the rail portion 370 in such a manner as to intersect the longitudinal direction of the rail portion 370 and have a predetermined spacing distance therebetween . Accordingly, the spacing of the plurality of main cassettes 320 (322) can be freely adjusted according to the width of the battery 10.

Referring to FIGS. 3 and 5A, the rail 370 is a hollow structure having an opening 372 at an upper portion thereof. Each of the plurality of main cassettes 320 (322) is coupled to a coupling member 350 passing through the opening 372. In this case, it is preferable that the fastening member 350 is introduced from above the bottom of the outer frame 370, and the end thereof is received and supported in the inner space of the hollow rail 370.

On the other hand, a coupling hole 323 for coupling the coupling member 350 is formed on the flange at the lower side of the side of the bidirectional main cassette 322 according to the embodiment of FIG. Directional main cassette 322 is formed in the longitudinal direction of the bidirectional main cassette 322 and the bidirectional main cassette 322 is provided at the rail portion 370 , The fastening holes 323 are arranged in a direction perpendicular to the longitudinal direction of the rail portion 370. As shown in Fig. Thus, when at least a part of the plurality of fastening holes 323 is formed as a long hole, the tolerance problem with respect to the fastening position between the bidirectional main cassette 322 and the rail portion 370 can be effectively solved.

In this embodiment, the fastening holes 323 are formed on both sides of the bidirectional main cassette 322, and each bidirectional main cassette 322 in one rail portion 290 is made to be more rigid at two points . Directional main cassette 322 is positioned at the outermost position according to the width of the battery and does not interfere with other similar or different parts of the tray 30. Therefore, It is not particularly problematic.

5 (a), guide grooves 314 formed in the longitudinal direction inside the sidewalls of the outer frame 310 to guide the installation of the main cassette 320 are selectively provided . The guide groove 314 is used to identify the center of the tray 30 and is used as a reference for seating an assembly jig (not shown) accompanying the assembly of the tray 30, .

In addition, a cushioning member 318 may be optionally provided at an appropriate position outside the upper sidewall of the outer frame 310. For example, when the tray 30 is continuously carried on the conveying conveyor, It is possible to effectively prevent the outer frame 310 or the battery 10 accommodated therein from being damaged by the collision between the adjacent trays 30 when it is stopped.

6 and 9 illustrate an assembly and an exploded perspective view of the tray 30 according to a second embodiment of the present invention. FIG. 8 is a perspective view of the main cassette 320 (322, 324) Sectional view of the portion 370, and Fig. 9 is a plan view. The present embodiment shows an example in which the battery mounting portion is modified in accordance with the type of the battery 10 accommodated in the tray 10. [

In this embodiment, as in the first embodiment, the battery mounting portion is provided as a plurality of main cassettes 320 (322, 324), and the plurality of main cassettes accommodate the unidirectional battery 10 shown in FIG. Way main cassette 322 and a pair of unidirectional main cassettes 323 disposed therebetween.

In this case, the lead 13 provided on one side of the unidirectional battery 10 is inserted and supported in the slot 322s of the bidirectional main cassette 322, and the end opposite to the battery 10 on which the lead 13 is not formed, And is inserted and supported in the slot 324s of the main cassette 324. Accordingly, a plurality of unidirectional batteries 10 can be accommodated in the tray 30 in two rows.

The structure of the bidirectional main cassette 322 and the coupling with the rail 370 are the same as those of the first embodiment. That is, it is preferable that a fastening hole 323 is formed on both sides of the bidirectional main cassette 322 for a firm fastening and that the fastening member 350 is used to fasten two points, 352 and the nut 354 are locked and unlocked, the fixing and unfastening between the bidirectional main cassette 322 and the rail 370 are performed.

However, unlike the bidirectional main cassette 324, the pair of the short-axis main cassettes 323 are preferably adjacent to each other at the center of the tray 30 in order to firmly engage with the rail 370 It is necessary to minimize the dead space between them. For this purpose, the two-point fastening for solid coupling between the unidirectional main cassette 323 and the rail 370 is achieved by fastening the fastening member 350 through the fastening holes 325 provided in the side flanges of the unidirectional main cassette 323, And an engaging member 360 provided on a lower surface of the unidirectional main cassette 323.

The latching member 360 may be provided as a separate member or may be integrally provided with the unidirectional main cassette 323. The latching member 260 is composed of a small-diameter body 362 and a large-diameter head 364. Since the head 364 does not directly pass through the opening 372, the head 364 of the engaging member 360 is inserted into the hollow portion 370 in the course of mounting the unidirectional main cassette 323 on the rail portion 370, A groove 374 is provided in a predetermined region of the rail portion 370 so as to be easily introduced into the inner space of the portion 370 (see also a partial enlarged view of FIG. 7). The engaging member 360 is introduced through the groove 374 of the rail portion 370 and slid to a predetermined position so that the body 362 is inserted into the opening portion 372 and the head 364 is placed in the inner space. Since the locking member 360 is provided on the lower surface of the unidirectional main cassette 323 and its length can not be adjusted, when the locking member 350 located on the opposite side is locked, the locking member 360 is lifted, And operates in such a manner that the head 374 is fixed by being in close contact with the inner upper portion. On the contrary, when the fastening member 350 is released from the locked state, the fastening state between the fastening member 360 and the rail 370 is released.

9, a pair of unidirectional main cassettes 324 disposed adjacent to each other at the center of the tray 30 are arranged in a staggered manner in the slots 324s of the unidirectional main cassette 324, so that the batteries 10 accommodated in any one row It can be prevented that it is released to another column.

Fig. 10 shows a plan view of the tray 30 according to the third embodiment of the present invention. The tray 30 according to the present embodiment has a pair of bidirectional main cassettes 322 positioned on the outside and another pair of bidirectional main cassettes 322a positioned on the center. The coupling between the bidirectional main cassettes 322 and 322a and the rail portion 370 is the same as in the above-described embodiments. The present embodiment is a structure in which a pair of unidirectional main cassettes 324 provided adjacent to each other at the center of the tray 30 according to Fig. 9 is replaced with a pair of bidirectional main cassettes 322a, and two pairs of bidirectional main cassettes 322 , 322a of the battery 10 to be received and supported. In this case, the slots 322s and 322as provided in the pair of bidirectional main cassettes 322 and 322a accommodate the lid 13 of the battery 10 or the opposite ends of the battery 10 in which the lid 13 is not formed Both can accommodate both bidirectional and unidirectional batteries.

The thickness controlling cassette 330 has a cross-sectional shape bent according to the lower end shape of the bidirectional main cassette 322 and is detachably coupled to the bidirectional main cassette 322 using bolts.

The thickness-adjusting cassette 330 functions to compensate for a change in the thickness of the lead 10 of the battery 10. Specifically, when accommodating different kinds of batteries 10 in the same tray 30, the thickness of the modified lead 10 of the battery 10 is significantly larger than the width of the slots 322s of the bidirectional main guide 322 It is difficult to maintain the upright state of the battery 10 by merely inserting the battery 10 into the slot 322s of the previous main guide 322. Therefore, it is necessary to compensate for this. In this case, the use of the thickness-adjusting cassette 330 having the slot 322s having the same width as the slot 322s of the bidirectional main cassette 322, The battery 10 lead 13 having a reduced thickness can be received and supported in a good standing state without being inclined by the slot 322s of the thickness adjusting cassette 330 without reinstallation.

The height-adjusting cassette 340 has a cross-sectional shape bent in accordance with the shape of the lower end of the two-way main cassette 322 and is detachably coupled to the two-way main cassette 322 using bolts. On the other hand, the thickness adjusting cassette 330 according to FIG. 11 is also illustrated as being installed with the height adjusting cassette 340 on the opposite side of the receiving area of the battery 10.

The height-adjusting cassette 340 functions to compensate the height of the lead 10 of the battery 10 when the height or height of the battery 10 changes. For example, in the case of accommodating different kinds of batteries 10 in the same tray 30, the tolerance range in which the longitudinal height of the changed lead 10 of the battery 10 can contact the charge / For example, if the error range is +/- 10mm, it can be used as it is, but it needs to be compensated if it goes away. The height of the battery 10 can be compensated by the height adjustment cassette 340 without replacement or reinstallation of the bidirectional main guide 322 by using the height adjustment cassette 340, Discharge position.

On the other hand, when the overall size of the battery 10 is reduced, the thickness of the cell 11 is generally reduced along with the thickness of the lead 10 of the battery 10. In this case, it is preferable to compensate for the thickness variation of the cell 11 to facilitate the upright reception of the battery 10 and allow the cell 11 of the battery 10 to be seated without being damaged by the load, A thickness adjusting groove 340h may be selectively formed in the height adjusting cassette 340. [ It is preferable that the thickness adjusting groove 340h is formed at the same interval as the slot of the bidirectional main cassette 322 and its width is made small.
