Description

Technology Field

Background Technology

[0003] One of the critical aspects of the secondary battery production process is quality control, which verifies whether the batteries provide the desired performance and safety. In this context, quality control involves accurately assessing whether the batteries possess proper charge and discharge capabilities to produce high-quality products while weeding out defective ones. Effective quality control enables the production of high-quality secondary batteries.

[0004] Meanwhile, in the secondary battery manufacturing process, there is a process in which an electrode is adsorbed and transported by vacuum pressure acting in a belt-side suction hole formed on the conveyor belt.

[0005] At this time, in order to stably transport the electrode at high speed in the high-speed NOTCHING equipment, the remaining part of the electrode, excluding the dimensional inspection part, must be transported via a conveyor belt (suction belt) in order to stably perform dimensional inspection and electrode transport.

[0006] However, in the past, in order to transport wide electrodes (500 mm or more), a wide conveyor belt and a motor capable of transporting a drive unit of 500 mm or more at high speed were required, and there was a problem of high motor load.

[0007] Furthermore, there is a problem in that, in order to transport not only wide electrodes but also short electrodes (electrodes narrower than 500mm), it is necessary to replace not only the intermediate guide plate but also other parts such as the conveyor belt for jelly roll cutting and the inner electrode suction block. In other words, the existing system faces the issue of having to replace other parts, such as the conveyor belt and the inner electrode suction block, depending on the width of the transported electrode.

[0044] Meanwhile, according to the present invention, a first moving frame (150) and a second moving frame (160) are combined so as to be movable in the width direction of a main conveyor frame (140), and a first conveyor belt (170) and a second conveyor belt (180) pass through the first moving frame (150) and the second moving frame (160), respectively, and travel in an endless track, and the first moving frame (150) and the first conveyor belt (170) and the second moving frame (160) and the second conveyor belt (180) are each moved by a moving operating unit to narrow in a direction closer to each other or to spread out in a direction further apart along the width direction of the main conveyor frame (140), thereby providing an electrode transport method using a twin conveyor system for electrode transport, wherein when the length of the electrode for a secondary battery transported by the first conveyor belt (170) and the second conveyor belt (180) changes, the A secondary battery electrode transfer method is provided, characterized by increasing or decreasing the distance between the first moving frame (150) and the first conveyor belt (170) and the second moving frame (160) and the second conveyor belt (180).

[0046] According to the present invention with the above-described configuration, the first conveyor belt (170) and the second conveyor belt (180) are configured to pass through the outer surfaces of the belt driving roller (214) and the belt driving guide roller (SR) provided on the first moving frame (150) and the second moving frame (160), respectively. When each belt driving roller (214) rotates due to the rotation of the motor shaft of the first belt driving motor (210) and the second belt driving motor (220), the first conveyor belt (170) and the second conveyor belt (180) travel in an endless track by passing through the outer surfaces of the belt driving roller (214) and the belt driving guide roller (SR), and the first moving frame (150) and the second moving frame (160), respectively. The electrode (2) placed on the first conveyor belt (170) is suction inside the first conveyor frame. The electrode (2) placed on the second conveyor belt (180) is in a state of being adsorbed by vacuum pressure through a plurality of first belt suction holes penetrating both sides of the first conveyor belt (170) and a second conveyor suction hole in communication with the suction space inside the second conveyor frame, and a plurality of second belt suction holes penetrating both sides of the second conveyor belt (180) is in a state of being adsorbed by vacuum pressure through vacuum pressure, and in this state, the first conveyor belt (170) and the second conveyor belt (180) travel in an endless track and transport the electrode (2).

[0047] In addition, in the present invention, when the motor shaft of the first moving drive motor (192) is rotated in one direction (e.g., counterclockwise) to rotate the first moving drive ball screw (194) in one direction (e.g., counterclockwise), the first moving drive ball screw nut (196) advances toward the longitudinal center of the main conveyor frame (140), and the first moving frame (150), belt driving roller (214), belt driving guide roller (SR), first conveyor belt (170), and first belt driving drive motor (210) coupled to the first moving drive ball screw nut (196) advance toward the longitudinal center of the main conveyor frame (140), and when the motor shaft of the first moving drive motor (192) is rotated in one direction (e.g., counterclockwise) to rotate the second moving drive ball screw (204) in one direction (e.g., counterclockwise), the second moving drive As the ball screw nut advances toward the longitudinal center of the main conveyor frame (140), and the second moving frame (160) coupled to the second moving drive ball screw nut (206), the belt driving roller (214), the belt driving guide roller (SR), the second conveyor belt (180), and the second belt driving drive motor (220) advance toward the longitudinal center of the main conveyor frame (140), the distance between the first conveyor belt (170) and the second conveyor belt (180) is narrowed, so that a relatively short-width electrode (electrode) can be transported while placed on the first conveyor belt (170) and the second conveyor belt (180).

[0048] When the motor shaft of the first moving drive motor (192) is rotated in a different direction (e.g., clockwise) to rotate the first moving drive ball screw (194) in a different direction (e.g., clockwise), the first moving drive ball screw nut (196) moves backward so as to move away from the longitudinal center of the main conveyor frame (140), and the first moving frame (150), belt driving roller (214), belt driving guide roller (SR), first conveyor belt (170), and first belt driving drive motor (210) coupled to the first moving drive ball screw nut (196) move backward so as to move away from the longitudinal center of the main conveyor frame (140), and when the motor shaft of the second moving drive motor (202) is rotated in a different direction (e.g., clockwise) to rotate the second moving drive ball screw (204) in a different direction (e.g., clockwise), the As the second moving drive ball screw nut (206) moves backward in a direction away from the longitudinal center of the main conveyor frame (140), and the second moving frame (160) coupled to the second moving drive ball screw nut (206), the belt driving roller (214), the belt driving guide roller (SR), the second conveyor belt (180), and the second belt driving drive motor (220) move backward in a direction away from the longitudinal center of the main conveyor frame (140), the distance between the first conveyor belt (170) and the second conveyor belt (180) becomes wider, so that a relatively wide electrode (electrode) can be transported while placed on the first conveyor belt (170) and the second conveyor belt (180). For example, in the present invention, the wide electrode (2) is an electrode with a distance of 500 mm or more between the upper and lower parts, and the short electrode (2) is an electrode with a distance of less than 500 mm between the upper and lower parts.

[0049] At this time, as illustrated in FIGS. 6 to 9, the first belt movement support projection (217) is seated and coupled to the first lower belt movement support groove (216) on the outer surface of the first belt driving roller (214), so that when the first moving frame (150), the first belt driving roller (214), and a pair of first upper belt driving rollers move in the width direction of the main conveyor frame (140), the first conveyor belt (170) is prevented from detaching from the first belt driving roller (214) and the pair of first upper belt driving rollers, thereby allowing the first moving frame (150) and the first conveyor belt (170) to move together along the width direction of the main conveyor belt.

[0050] In addition, the second belt movement support projection (227) is seated and coupled to the second lower belt movement support groove (226) on the outer surface (214) of the second belt driving roller, so that when the second moving frame (160), the second belt driving roller (224), and a pair of second upper belt driving rollers move in the width direction of the main conveyor frame (140), the second conveyor belt (180) is prevented from detaching from the second belt driving roller (224) and the pair of second belt driving rollers (224), thereby allowing the second moving frame (160) and the second conveyor belt (180) to move together along the width direction of the main conveyor belt.

[0051] Meanwhile, referring to FIGS. 10 and 11, in the present invention, when the first belt tension adjustment bolt (238) is rotated in one direction (e.g., counterclockwise) to lower the first belt tension adjustment bolt (238) relative to the first tension adjustment support bracket (234), the first tension adjustment roller (236), to which a roller shaft (ROS) is coupled to the first tension adjustment slit (235) so as to be movable relative to it, lowers and pulls the first conveyor belt (170) downward, thereby increasing the tension of the first conveyor belt (170). When the first belt tension adjustment bolt (238) is rotated in one direction (e.g., clockwise) to raise the first belt tension adjustment bolt (238) relative to the first tension adjustment support bracket (234), the first tension adjustment roller (236), to which a roller shaft (ROS) is coupled to the first tension adjustment slit (235) so as to be movable relative to it, As the roller (236) rises, it reduces the force pulling the first conveyor belt (170) downward, thereby reducing the tension of the first conveyor belt (170).

[0052] Meanwhile, referring to FIGS. 12 and 13, in the present invention, when the second belt tension adjustment bolt (248) is rotated in one direction (e.g., counterclockwise) to lower the second belt tension adjustment bolt (248) relative to the second tension adjustment support bracket (244), the second tension adjustment roller (246), to which a roller shaft (ROS) is coupled to the second tension adjustment slit (245) so as to be movable relative to it, lowers and pulls the second conveyor belt (180) downward, thereby increasing the tension of the second conveyor belt (180). When the second belt tension adjustment bolt (248) is rotated in one direction (e.g., clockwise) to raise the second belt tension adjustment bolt (248) relative to the second tension adjustment support bracket (244), the second tension adjustment roller (246), to which a roller shaft (ROS) is coupled to the second tension adjustment slit (245) so as to be movable relative to it, As the roller (246) rises, it reduces the force pulling the second conveyor belt (180) downward, thereby reducing the tension of the second conveyor belt (180).

[0053] Therefore, since the tension of the first conveyor belt (170) and the second conveyor belt (180) can be adjusted, the effect of enabling smoother transport of the electrodes carried on the first conveyor belt (170) and the second conveyor belt (180) can be expected.
