BEST MODE

[0030] In the present application, it should be understood that the terms “comprises,” “has,” “includes,” etc. specify the presence of stated features, numbers, steps, operations, elements, components, or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, steps, operations, elements, components, or combinations thereof.

[0031] In addition, the same reference numbers will be used throughout the drawings to refer to parts that perform similar functions or operations. In the case in which one part is said to be connected to another part in the specification, not only may the one part be directly connected to the other part, but also, the one part may be indirectly connected to the other part via a further part. In addition, that a certain element is included does not mean that other elements are excluded, but means that such elements may be further included unless mentioned otherwise.

[0032] Hereinafter, a battery cell transfer apparatus according to the present invention will be described with reference to the accompanying drawings.

[0033] FIG. 2 is a perspective view schematically showing a battery cell transfer apparatus according to an embodiment of the present invention.

[0034] When describing the battery cell transfer apparatus 1000 according to the present invention in detail with reference to FIG. 2, the battery cell transfer apparatus 1000 according to the present invention includes an electrode tab protection device 100 configured to protect an electrode tab 11 of a battery cell 10 and two opposite jigs 200 configured to press and fix the battery cell 10 at opposite sides thereof, whereby it is possible to prevent short circuit of or damage to the electrode tab 11 during a battery cell transfer process.

[0035] When describing the electrode tab protection device 100 in more detail with reference to FIG. 3, the electrode tab protection device 100 includes an electrode tab insertion portion 110, into which the electrode tab is inserted, and a fixing portion 120 configured to fix the electrode tab insertion portion 110 in order to prevent movement of the electrode tab insertion portion.

[0036] Here, the size of the electrode tab insertion portion 110 may be appropriately selected within a range within which the entirety of the electrode tab 11 is protected and the electrode tab 11 is not damaged when the electrode tab 11 is inserted or separated in consideration of the length and the thickness of the electrode tab 11 that is inserted into the electrode tab insertion portion. It is preferable for the electrode tab insertion portion 110 to be made of an electrically insulative material in order to prevent occurrence of short circuit.

[0037] Meanwhile, the fixing portion 120 has a structure in which one side of the fixing portion is connected to the electrode tab insertion portion 110 and the other side of the fixing portion is coupled to the jigs 200 in order to fix the electrode tab insertion portion 110. Although any of various well-known methods may be used as a method of coupling the fixing portion to the jigs 200, it is preferable for the fixing portion to be coupled to the jigs in a clip form in consideration of work convenience and repetitive use.

[0038] In addition, the position at which one side of the fixing portion 120 is connected to the electrode tab insertion portion 110 may be arbitrarily selected within a range within which it is possible to fix the electrode tab insertion portion 110. For example, one side of the fixing portion 120 may be located at any one of opposite ends of the electrode tab insertion portion 110, as shown in (a) and (b) of FIG. 4, or one side of the fixing portion 120 may be located between the opposite ends of the electrode tab insertion portion 110, as shown in (c) of FIG. 4.

[0039] Meanwhile, the two jigs 200 are located at opposite surfaces of the battery cell 10 to press and fix the battery cell 10 disposed therebetween. The jigs 200 are provided with jig fastening portions 210 configured to fix the two opposite jigs 200.

[0040] In the drawings of the present invention, the case in which the jig fastening portions 210 are constituted by fastening holes formed in the vicinity of corners of the jigs 200 and bolts and nuts inserted through the fastening holes to fix the jigs 200 is shown. However, the jig fastening portions 210 are not limited thereto, and it is possible to fix the battery cell 10 while pressing the battery cell between the two jigs 200 using various well-known methods.

[0041] Meanwhile, FIG. 5 shows a method of fixing the battery cell 10 to the battery cell transfer apparatus 1000 according to the present invention. First, the two jigs 200 are disposed at opposite surfaces of the battery cell 10, the two jigs 200 are fastened and fixed to each other through the jig fastening portions 210, the electrode tab 11 of the battery cell 10 is inserted into the electrode tab insertion portion 110 of the electrode tab protection device 100, and the fixing portion 120 is fixed to the jigs 200.

[0042] Subsequently, the battery cell transfer apparatus 1000 including the battery cell 10 may be safely transferred to a desired process, and the battery cell may be used in the state in which the electrode tab protection device 100 and the jigs 200 are removed, as needed.

[0043] Although the specific details of the present invention have been described in detail, those skilled in the art will appreciate that the detailed description thereof discloses only preferred embodiments of the present invention and thus does not limit the scope of the present invention. Accordingly, those skilled in the art will appreciate that various changes and modifications are possible, without departing from the category and the technical idea of the present invention, and it will be obvious that such changes and modifications fall within the scope of the appended claims.
