Abstract: Proposed is a vacuum carrier. The vacuum carrier includes a vacuum base having vacuum passages (20VP and 30VP) formed therein, the vacuum passages (20VP and 30VP) being connected to vacuum suction holes (24 and 34), and includes a vacuum unit configured to form a vacuum by suctioning air from the vacuum passages (20VP and 30VP) inside the vacuum base. Further, the vacuum unit includes a vacuum filling block (51) having suction ports connected to a vacuum apparatus, and includes a movement driving apparatus configured to move the vacuum filling block (51) such that the suction ports of the vacuum filling block (51) are connected to the vacuum passages (20VP and 30VP) inside the vacuum base.

Abstract: The objective of the present invention is to provide a conveyor for discharging scraps of a laser notching machine. The present invention comprises: a conveyor (20); a suction duct (52) which is connected to the conveyor (20) so as to suck, from the conveyor, scraps (2S) generated when a tab (2C) is formed on a pole plate (2) passing through the conveyor (20); and a scrap discharge hole (34) for sucking and discharging the scraps (2S) from the conveyor (20), wherein the conveyor (20) includes: a conveyor body (22); and a conveyor belt (24) for performing a continuous track motion so as to pass the upper and lower surfaces of the conveyor body (22), wherein the conveyor body (22) has a vacuum sector (22VS) and a vacuum release sector (22RS), the vacuum sector (22VS) is configured to have a vacuum suction hole communicating from the inner space portion of the conveyor body (22) to the bottom surface of the conveyor body (22), and the scrap discharge hole (34) is disposed under the vacuum release sector (22RS).

Abstract: Proposed is a pouch cutter for a secondary battery. The pouch cutter includes a bottom knife (20) having a blade and a top knife (30) having a blade disposed to be adjacent to the blade of the bottom knife (20), wherein the blade of the bottom knife (20) and/or the blade of the top knife (30) are formed at an acute angle, the bottom knife (20) and the top knife (30) are cutters having a square cross section, and at least the top knife (30) from among the top knife (30) and the bottom knife (20) has a first top knife blade (35A), a second top knife blade (35B), a third top knife blade (35C), and a fourth top knife blade (35D), which are formed at an acute angle so as to be adjacent to four corners of the top knife.

Abstract: Proposed is a secondary battery manufacturing process carrier having a carrier transporting track structure. The secondary battery manufacturing process carrier includes: a carrier base (20); a carrier roller (30) provided at a first side of the carrier base (20); a rolling member (40) provided at a second side of the carrier base (20); and a track base (10) on which the carrier base (20) is movably disposed. The carrier base (20) has a first carrier side plate (122) and a second carrier side plate (124) at left and right sides thereof, the first carrier side plate (122) and the second carrier side plate (124) include the carrier roller (30) and the rolling member (40), respectively, and the carrier roller (30) and the rolling member (40) are configured to be rolled on the track base (10).
