DETAILED DESCRIPTION

[0033] The present disclosure is described in detail below with reference to the accompanying drawings. However, the person skilled in the art will recognize that such embodiments are provided to further illustrate the spirit of the present disclosure and do not limit the subject matter to be protected as disclosed in the detailed description and the accompanying claims.

[0034] One embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0035] Fig. Figure 1 is a view that represents a complex system 1 according to one embodiment.

[0036] The complex system 1 can perform both an indentation process and a stacking process in a single operation, wherein the indentation process is a process in which an electrode is formed by forming and cutting a tab on an electrode foil, and the stacking process is a process in which an electrode assembly 6 is formed by stacking a negative electrode 5n, a separator 7 and a positive electrode 5p.

[0037] The complex system 1 according to one embodiment may include: a positive electrode manufacturing machine 30p configured to form the positive electrode 5p by forming and cutting a tab on a positive electrode foil 3p moving in a first direction D1; a negative electrode manufacturing machine 30n configured to form the negative electrode 5n by forming and cutting a tab on a negative electrode foil 3n moving in the first direction D1, the negative electrode manufacturing machine 30n being arranged parallel to the positive electrode manufacturing machine 30p; a positive electrode first-direction forwarding machine 40p configured to forward the positive electrode 5p output by the positive electrode manufacturing machine 30p in the first direction D1;a negative electrode first direction relay machine 40n configured to relay the negative electrode 5n, which is output by the negative electrode manufacturing machine 30n, in the first direction D1; at least one first stacker 60a positioned on a side opposite the negative electrode first direction relay machine 40n with respect to the positive electrode first direction relay machine 40p and configured to form the electrode assembly 6 by stacking the positive electrode 5p, the separator 7 and the negative electrode 5n;at least one second stacker 60b, positioned on the opposite side of the positive electrode first direction forwarding machine 40p with respect to the negative electrode first direction forwarding machine 40n, and configured to form the electrode assembly 6 by stacking the positive electrode 5p, the separator 7, and the negative electrode 5n; at least one positive electrode second direction forwarding machine 50p, configured to forward the positive electrode 5p, which is forwarded by the positive electrode first direction forwarding machine 40p, in a second direction D2 and to supply the positive electrode 5p to the first stacker 60a and the second stacker 60b;and at least one negative electrode second-direction forwarding machine 50n configured to forward the negative electrode 5n, which is forwarded from the negative electrode first-direction forwarding machine 40n, in the second direction D2 and to supply the negative electrode 5n to the first stacker 60a and the second stacker 60b.

[0038] The complex system 1 according to one embodiment may further include: a positive electrode unwinder 20p configured to feed the positive electrode foil 3p to the positive electrode manufacturing machine 30p by unwinding a positive electrode foil roll 2p in the first direction D1; and a negative electrode unwinder 20n configured to feed the negative electrode foil 3n to the negative electrode manufacturing machine 30n by unwinding a negative electrode foil roll 2n in the first direction D1.

[0039] The complex system 1 according to one embodiment may further include: a positive electrode reel changer 10p configured to unload a spent positive electrode foil reel 2p and replace the spent positive electrode foil reel 2p with a new positive electrode foil reel 2p when the positive electrode foil reel 2p is spent in the positive electrode unwinder 20p; and a negative electrode reel changer 10n configured to unload a spent negative electrode foil reel 2n and replace the spent negative electrode foil reel 2n with a new negative electrode foil reel 2n when the negative electrode foil reel 2n is spent in the negative electrode unwinder 20n.

[0040] In the complex system 1, a positive electrode line, in which the positive electrode reel changer 10p, the positive electrode unwinder 20p, the positive electrode manufacturing machine 30p and the positive electrode first direction forwarding machine 40p are connected, and a negative electrode line, in which the negative electrode reel changer 10n, the negative electrode unwinder 20n, the negative electrode manufacturing machine 30n and the negative electrode first direction forwarding machine 40n are connected, can be arranged parallel to each other along the first direction D1.

[0041] The positive electrode first-direction conveying machine 40p and the negative electrode first-direction conveying machine 40n can include a conveyor belt, a linear motion system (LBS), and other devices capable of conveying an electrode. The positive electrode 5p and the negative electrode 5n, produced in the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n, can be directly fed to the positive electrode first-direction conveying machine 40p and the negative electrode first-direction conveying machine 40n. The positive electrode first-direction conveying machine 40p and the negative electrode first-direction conveying machine 40n can convey the positive electrode 5p and the negative electrode 5n in the first direction D1.The positive electrode 5p and the negative electrode 5n, which are forwarded in the first direction D1, can be fed to the first stacker 60a and the second stacker 60b by the positive-electrode-second-direction forwarding machine 50p and the negative-electrode-second-direction forwarding machine 50n.

[0042] Since the positive electrode 5p and the negative electrode 5n are not stored in a magazine after they have been manufactured, damage to the positive electrode 5p and the negative electrode 5n, which can occur during the storage and removal process, is prevented. For example, various types of damage could occur, such as bending of the positive electrode 5p due to a collision between the magazine and an edge of the positive electrode 5n, tearing, breakage of the active material, and so on.The positive electrode 5p and the negative electrode 5n can be moved by the positive-electrode-first-direction transfer machine 40p and the negative-electrode-first-direction transfer machine 40n, and then fed to the stackers by the positive-electrode-second-direction transfer machine 50p and the negative-electrode-second-direction transfer machine 50n. Therefore, damage that could occur during a transfer process of the positive electrode 5p and the negative electrode 5n can be minimized.

[0043] The first stacker 60a and the second stacker 60b can each be arranged on an outer side face of the positive electrode line and on an outer side face of the negative electrode line, respectively. Accordingly, a worker can perform the work required for the first stacker 60a and the second stacker 60b from outside the positive electrode line and the negative electrode line. In particular, the first stacker 60a can be arranged on the opposite side of the negative electrode first direction relay machine 40n with respect to the positive electrode first direction relay machine 40p. The second stacker 60b can be arranged on the opposite side of the positive electrode first direction relay machine 40p with respect to the negative electrode first direction relay machine 40n.The positive electrode first direction relay machine 40p and the negative electrode first direction relay machine 40n can be arranged between the first stacker 60a and the second stacker 60b.

[0044] Since the first stacker 60a and the second stacker 60b are not positioned between the positive electrode line and the negative electrode line, but are positioned outside the positive electrode line and the negative electrode line, the worker can easily access the first stacker 60a and the second stacker 60b. The worker can access automation equipment (the positive electrode unwinder 20p, the negative electrode unwinder 20n, the positive electrode reel changer 10p, the negative electrode reel changer 10n, the positive electrode manufacturing machine 30p, the negative electrode manufacturing machine 30n, the first direction forwarding machines 40p and 40n, the second direction forwarding machines 50p and 50n, the first stacker 60a and the second stacker 60b) that require maintenance work from outside the positive electrode line and the negative electrode line.Since only one positive electrode bridge 70p and one negative electrode bridge 70n are positioned between the positive electrode line and the negative electrode line, the distance between the positive and negative electrode lines can be reduced. This means that the left and right dimensions (a length in the second direction D2) of the complex system 1 can be minimized. Consequently, the worker's path from the outside of the positive electrode line to the outside of the negative electrode line can be minimized. Additionally, the area occupied by the complex system 1 can be reduced, thus reducing the overall area of ​​the manufacturing plant. This means that the space in a secondary battery manufacturing plant can be used efficiently.

[0045] The positive electrode second-direction relay machine 50p can include: the positive electrode bridge 70p, which is positioned between the positive electrode first-direction relay machine 40p and the negative electrode first-direction relay machine 40n and on which the positive electrode 5p is placed; a first positive electrode feeder 50p1, which is configured to feed the positive electrode 5p on the positive electrode first-direction relay machine 40p to the first stacker 60a and to move another positive electrode 5p on the positive electrode first-direction relay machine 40p to the positive electrode bridge 70p; and a second positive electrode feeder 50p2 configured to feed the positive electrode 5p onto the positive electrode bridge 70p to the second stacker 60b.

[0069] Each of the first stacker 60a and the second stacker 60b can be configured as a rotary-type stacker. In the rotary-type stacker, a rotary stacking table 64a, on which the positive electrode 5p, the separator 7, and the negative electrode 5n are stacked, is configured to rotate back and forth at a predetermined angle about a rotational axis RA0. The rotary-type stacker can include: the positive electrode alignment table 61, configured to align a position of the positive electrode 5p; the negative electrode alignment table 62, configured to align a position of the negative electrode 5n; and a first rotary receiver section 63a, configured to pick up the positive electrode 5p on the positive electrode alignment table 61 and move the positive electrode 5p to the rotary stacking table 64a.a second rotary receiver part 63b configured to receive the negative electrode 5n on the negative electrode alignment table 62 and to move the negative electrode 5n to the rotary stacking table 64a; the rotary stacking table 64a configured to be rotated back and forth about the rotation axis RA0 at the predetermined angle, the rotary stacking table 64a having an upper surface on which the positive electrode 5p, the separator 7, and the negative electrode 5n are stacked; and a separator feeder part 65 configured to deliver the separator 7 onto an upper surface of a stationary stacking table 64b.

The rotating stacking table 64a can be rotated by a predetermined angle so that its upper surface faces the first rotating sensor 63a. As the rotating stacking table 64a is rotated, the separator 7 can cover the rotating stacking table 64a (or the negative electrode 5n). The first rotating sensor 63a can place the positive electrode 5p onto the separator 7 on the upper surface of the rotating stacking table 64a. The second rotating sensor 63b can pick up the negative electrode 5n on the negative electrode alignment table 62.

The rotating stacking table 64a can be rotated by a predetermined angle so that its upper surface faces the second rotating sensor 63b. When the rotating stacking table 64a is rotated, the separator 7 can cover the positive electrode 5p (or the rotating stacking table 64a). The second rotating sensor 63b can place the negative electrode 5n onto the separator 7 on the upper surface of the rotating stacking table 64a. The first rotating sensor 63a can pick up the positive electrode 5p onto the positive electrode alignment table 61.

After the rotary stacker repeats the first stacking section G1 and the second stacking section G2 a specified number of times, the formed electrode assembly 6 can be ejected. The electrode assembly 6 can be retrieved from the rotary stacker by a device using a robot arm and a gripper.

[0076] Fig. Figure 7 is a view showing a stationary-type forklift according to one embodiment.

[0077] Each of the first stacker 60a and the second stacker 60b can be configured as a stationary-type stacker. In the stationary-type stacker, the stationary stacking table 64b, on which the positive electrode 5p, the separator 7, and the negative electrode 5n are stacked, does not move. The stationary-type stacker can include: the positive electrode alignment table 61, configured to align one position of the positive electrode 5p; the negative electrode alignment table 62, configured to align one position of the negative electrode 5n; and a third rotary receiver 63c, configured to pick up the positive electrode 5p on the positive electrode alignment table 61 and move the positive electrode 5p to the stationary stacking table 64b.a fourth rotary receiver part 63d, configured to receive the negative electrode 5n on the negative electrode alignment table 62 and to move the negative electrode 5n to the stationary stacking table 64b; the stationary stacking table 64b, which has an upper surface on which the positive electrode 5p, the separator 7 and the negative electrode 5n are stacked; the separator feed part 65, configured to dispense the separator 7 onto the upper surface of the stationary stacking table 64b; and a separator guide part 66, configured to guide the separator 7 such that the separator 7 covers either the positive electrode 5p or the negative electrode 5n.

[0078] The third rotary sensor section 63c can be rotated about a rotation axis RA3, so that it moves back and forth between the positive electrode alignment table 61 and the stationary stacking table 64b. The rotation axis RA3 of the third rotary sensor section 63c can be positioned below the positive electrode alignment table 61. To receive and position the positive electrode 5p, the length of the third rotary sensor section 63c can be adjusted in a direction extending from the rotation axis RA3. The fourth rotary sensor section 63d can be rotated about a rotation axis RA4, so that it moves back and forth between the negative electrode alignment table 62 and the stationary stacking table 64b. The rotation axis RA4 of the fourth rotary sensor part 63d can be positioned below the negative electrode alignment table 62.To receive and position the negative electrode 5n, a length of the fourth rotary sensor part 63d can be adjusted in a direction originating from the rotation axis RA4.

The separator guide part 66 can be configured to guide the separator 7 such that the separator 7 covers the positive electrode 5p or the negative electrode 5n, while the separator guide part 66 moves the pair of rollers back and forth to a predetermined angle relative to the positive electrode alignment table 61 and the negative electrode alignment table 62.

[0080] In a third stacking section, the separator guide part 66 can move the pair of rollers to the positive electrode alignment table 61 such that the separator 7 is guided in such a way that the separator 7 covers the stationary stacking table 64b (or the positive electrode 5p). The fourth rotary receiver part 63d can place the negative electrode 5n on the separator 7 on the upper surface of the stationary stacking table 64b. The third rotary receiver part 63c can pick up the positive electrode 5p on the positive electrode alignment table 61. The negative electrode feeder can feed the negative electrode 5n to the negative electrode alignment table 62.

[0081] In a fourth stacking section, the separator guide part 66 can move the pair of rollers to the negative electrode alignment table 62 such that the separator 7 is guided in such a way that it covers the negative electrode 5n (or the stationary stacking table 64b). The third rotary receiver part 63c can place the positive electrode 5p on the separator 7 on the upper surface of the stationary stacking table 64b. The fourth rotary receiver part 63d can pick up the negative electrode 5n on the negative electrode alignment table 62. The positive electrode feeder can feed the positive electrode 5p to the positive electrode alignment table 61.

[0082] The sequence of the third stacking section and the fourth stacking section can be determined in such a way that it corresponds to an operating sequence of the positive electrode feeding machines 50p1 and 50p2 and the negative electrode feeding machines 50n1 and 50n2.

[0083] When the stationary stacker repeats the third and fourth stacking stages, the electrode assembly 6, on which the positive electrode 5p, the separator 7, and the negative electrode 5n are stacked, can be formed on the upper surface of the stationary stacker. After the stationary stacker repeats the third and fourth stacking stages a specified number of times, the formed electrode assembly 6 can be ejected. The electrode assembly 6 can be retrieved from the stationary stacker by a device using a robot arm and gripper.

[0084] Fig. Figure 8 is a view that depicts every operation of the first positive electrode feeder 50p1 and the second positive electrode feeder 50p2 according to an embodiment in the first movement section E1 and the second movement section E2. Fig. Figure 8 shows the first positive electrode feeding machine 50p1 and the second positive electrode feeding machine 50p2 in a direction in which the positive electrode manufacturing machine 30p is viewed from the positive electrode unwinder 20p. Fig. Figure 9 is a view that depicts every operation of the first positive electrode feeder 50p1 and the second positive electrode feeder 50p2 according to an embodiment in the first movement section E1 and the second movement section E2. Fig. Figure 9 shows the first positive electrode feeding machine 50p1 and the second positive electrode feeding machine 50p2 in a direction in which the negative electrode manufacturing machine is viewed from the negative electrode unwinder 20n. The present disclosure is made with reference to Fig. 2 and Fig. 3 described.

[0085] The positive electrode feeders 50p1 and 50p2 are devices configured to receive the positive electrode 5p, which is passed through the positive electrode first-direction forwarding machine 40p, and to feed the positive electrode 5p to the stacker. The positive electrode feeders 50p1 and 50p2 can include the first positive electrode feeder 50p1 and the second positive electrode feeder 50p2. The negative electrode feeders 50n1 and 50n2 are devices configured to receive the negative electrode 5n, which is passed through the negative electrode first-direction forwarding machine 40n, and to feed the negative electrode 5n to the stacker. The negative electrode feeding machines 50n1 and 50n2 can include the first negative electrode feeding machine 50n1 and the second negative electrode feeding machine 50n2.

[0086] The first positive electrode feeder 50p1 and the first negative electrode feeder 50n1 can be operated in the same sequence. The first positive electrode feeder 50p1 can receive the positive electrode 5p from the positive electrode first-direction transfer machine 40p and can feed the positive electrode 5p directly to the first stacker 60a. The first negative electrode feeder 50n1 can receive the negative electrode 5n from the negative electrode first-direction transfer machine 40n and can feed the negative electrode 5n directly to the second stacker 60b.

[0087] The first positive electrode feeder 50p1 can include: a first receiving part P1 configured to receive the positive electrode 5p on the positive electrode first direction transfer machine 40p and feed the positive electrode 5p to the first stacker 60a; a second receiving part P2 configured to receive the positive electrode 5p on the positive electrode first direction transfer machine 40p and move the positive electrode 5p to the positive electrode bridge 70p; and a first feeder drive part F1 configured to move the first receiving part P1 and the second receiving part P2 simultaneously in the second direction D2 perpendicular to the first direction D1.

[0088] The first negative electrode feeder 50n1 can include: a third receiving part P3 configured to receive the negative electrode 5n on the negative electrode first direction transfer machine 40n and feed the negative electrode 5n to the first stacker 60a; a fourth receiving part P4 configured to receive the negative electrode 5n on the negative electrode first direction transfer machine 40n and move the negative electrode 5n to the negative electrode bridge 70n; and a second feeder drive part F2 configured to move the third receiving part P3 and the fourth receiving part P4 simultaneously in the second direction D2 perpendicular to the first direction D1.

[0089] The second positive electrode feeder 50p2 and the second negative electrode feeder 50n2 can be operated in the same sequence. The second positive electrode feeder 50p2 can receive the positive electrode moved by the first positive electrode feeder 50p1 to the positive electrode bridge 70p and can feed the positive electrode to the second stacker 60b. The second negative electrode feeder 50n2 can receive the negative electrode moved by the first negative electrode feeder 50n1 to the negative electrode bridge 70n and can feed the negative electrode to the first stacker 60a.

[0090] The complex system 1 according to one embodiment can further include: a negative electrode floating table 80n, which is arranged above the positive electrode first direction transmission machine 40p such that the negative electrode floating table 80n is spaced apart from the positive electrode first direction transmission machine 40p and on which the negative electrode 5n is placed; and a positive electrode floating table 80p, which is arranged above the negative electrode first direction transmission machine 40n such that the positive electrode floating table 80p is spaced apart from the negative electrode first direction transmission machine 40n and on which the positive electrode 5p is placed.

[0091] The positive electrode floating table 80p is a position where the second positive electrode feeder 50p2 places the positive electrode 5p. The negative electrode floating table 80n is a position where the second negative electrode feeder 50n2 places the negative electrode 5n. Since the positive electrode floating table 80p is arranged above the negative electrode first-direction forwarding machine 40n such that the positive electrode floating table 80p is spaced apart from the negative electrode first-direction forwarding machine 40n, the positive electrode floating table 80p does not obstruct the negative electrode first-direction forwarding machine 40n from forwarding the negative electrode 5n.Since the negative electrode floating table 80n is arranged above the positive electrode first direction transmission machine 40p in such a way that the negative electrode floating table 80n is spaced apart from the positive electrode first direction transmission machine 40p, the negative electrode floating table 80n does not prevent the positive electrode first direction transmission machine 40p from transmitting the positive electrode 5p.

[0092] The second positive electrode feeder 50p2 can include: a fifth receiving part P5 configured to receive the positive electrode 5p on the positive electrode bridge 70p and feed the positive electrode 5p to the positive electrode floating table 80p; a sixth receiving part P6 configured to receive the positive electrode 5p on the positive electrode floating table 80p and move the positive electrode 5p to the second stacker 60b; and a third feeder drive part F3 configured to move the fifth receiving part P5 and the sixth receiving part P6 simultaneously in the second direction D2 perpendicular to the first direction D1.

[0093] The second negative electrode feeder 50n2 can include: a seventh receiving part P7 configured to receive the negative electrode 5n on the negative electrode bridge 70n and feed the negative electrode 5n to the negative electrode floating table 80n; an eighth receiving part P8 configured to receive the negative electrode 5n on the negative electrode floating table 80n and move the negative electrode 5n to the first stacker 60a; and a fourth feeder drive part F4 configured to move the seventh receiving part P7 and the eighth receiving part P8 simultaneously in the second direction D2 perpendicular to the first direction D1.

[0094] Each of the first positive electrode feeder 50p1, the first negative electrode feeder 50n1, the second positive electrode feeder 50p2, and the second negative electrode feeder 50n2 can equally include two pickup parts and one feeder drive part. The feeder drive part can simultaneously move two pickup parts in the second direction D2. The feeder drive part can move the two pickup parts back and forth in the second direction D2. When the two pickup parts are moved by the feeder drive part in the second direction D2 to a first side or a second side, a pickup operation or a pickup release operation can be performed. Within the two pickup parts, one of the two pickup parts can perform the pickup operation, and the other pickup part can perform the pickup release operation.Alternatively, the two pickup units can perform the pickup operation simultaneously, or they can perform the pickup release operation simultaneously. The four feeding machines have the same structure, comprising two pickup units and one feeding drive unit. Therefore, it is convenient to control and maintain a large number of feeding machines simultaneously. To utilize feeding machines with the same structure, the positive electrode floating table 80p and the negative electrode floating table 80n can each be mounted on feeder machines with different polarities.

[0095] The pickup operation is a process in which an electrode is lifted onto a table or a conveying machine. The pickup release operation is a process in which the electrode, lifted by the pickup element, is placed at a predetermined position. The pickup element can pick up or place the electrode using vacuum adsorption, a gripper, electromagnetic force, adhesive force, and so on. To pick up the electrode, the length of the pickup element can be adjusted in a third direction D3 perpendicular to the first direction D1 and the second direction D2. The second positive electrode feeder 50p2 and the second negative electrode feeder 50n2 can perform a length adjustment of the pickup element to pick up the electrode on the floating table.A process in which the feeder drive part moves the receiver part back and forth in the second direction D2, and the length adjustment process of the receiver part can be carried out in different ways using a slide, a motor, a gearbox, a robot arm, and so on.

[0096] The complex system 1 may further include: a negative electrode partition 90n positioned between the positive electrode first direction conveying machine 40p and the negative electrode floating table 80n, extending along a path along which the second negative electrode feeder 50n2 moves the negative electrode 5n, the negative electrode partition 90n being configured to prevent negative electrode particles falling from the negative electrode 5n from falling onto the positive electrode first direction conveying machine 40p;and a positive electrode partition 90p positioned between the negative electrode first direction conveying machine 40n and the positive electrode floating table 80p, extending along a path along which the second positive electrode feeder 50p2 moves the positive electrode 5p, the positive electrode partition 90p being configured to prevent positive electrode particles falling from the positive electrode 5p from falling onto the negative electrode first direction conveying machine 40n.

[0097] The negative electrode partition 90n can prevent foreign bodies, such as active negative electrode material, from being introduced into the positive electrode first-direction transfer machine 40p, as these foreign bodies fall from the negative electrode 5n during a process in which the negative electrode 5n is moved across the positive electrode first-direction transfer machine 40p. The negative electrode partition 90n is positioned between a path along which the positive electrode 5p is transferred and a path along which the negative electrode 5n is transferred, and can divide a space.

[0098] The negative electrode partition 90n can be formed in a plate form. The negative electrode partition 90n can be configured such that its width is wider than the width of the negative electrode floating table 80n. The negative electrode partition 90n can be configured along a path on which the second negative electrode feeder 50n2 moves. The negative electrode partition 90n can be positioned between the positive electrode first-direction transfer machine 40p and the negative electrode floating table 80n. The negative electrode partition 90n can be sufficiently spaced from the positive electrode first direction transmission machine 40p so that the positive electrode 5p is not prevented from moving on the positive electrode first direction transmission machine 40p.

[0099] In a process where the second negative electrode feeder 50n2 picks up and moves the negative electrode 5n, a section of the adhesive layer of the negative electrode 5n can detach and fall off. If this section of the falling adhesive layer comes into contact with the positive electrode 5p, or mixes with the positive electrode 5p through contact with the positive electrode first-direction transfer machine 40p, the function of the electrode assembly 6 can be impaired. The negative electrode spacer 90n prevents foreign matter, which may form during a process where the second negative electrode feeder 50n2 picks up and moves the negative electrode 5n, from coming into contact with the positive electrode 5p.

[0100] The positive electrode partition 90p can prevent foreign bodies, such as active positive electrode material, from being introduced into the negative electrode first-direction transfer machine 40n, as these foreign bodies fall from the positive electrode 5p during a process in which the positive electrode 5p is moved across the negative electrode first-direction transfer machine 40n. The positive electrode partition 90p is positioned between a path along which the positive electrode 5p is transferred and a path along which the negative electrode 5n is transferred, and can divide a space.

[0101] The positive electrode partition 90p can be formed in a plate form. The positive electrode partition 90p can be configured such that its width is wider than the width of the positive electrode floating table 80p. The positive electrode partition 90p can be configured along a path on which the second positive electrode feeder 50p2 moves. The positive electrode partition 90p can be positioned between the negative electrode first-direction transfer machine 40n and the positive electrode floating table 80p. The positive electrode partition 90p can be sufficiently spaced from the negative electrode first direction transmission machine 40n so that the negative electrode 5n is not prevented from moving on the negative electrode first direction transmission machine 40n.

[0102] In a process where the second positive electrode feeder 50p2 picks up and moves the positive electrode 5p, a section of the adhesive layer of the positive electrode 5p can detach and fall off. If this section of the falling adhesive layer comes into contact with the negative electrode 5n, or mixes with the negative electrode 5n through contact with the negative electrode first-direction transfer machine 40n, the function of the electrode assembly 6 can be impaired. The positive electrode intermediate wall 90p prevents foreign matter, which may form during a process where the second positive electrode feeder 50p2 picks up and moves the positive electrode 5p, from coming into contact with the negative electrode 5n.

[0103] The positive electrode bridge 70p can move the positive electrode 5p, which is moved by the first positive electrode feeder 50p1, to a position where the second positive electrode feeder 50p2 receives the positive electrode 5p, and the negative electrode bridge 70n can move the negative electrode 5n, which is moved by the first negative electrode feeder 50n1, to a position where the second negative electrode feeder 50n2 receives the negative electrode 5n.

[0104] The positive electrode bridge 70p and the negative electrode bridge 70n can be configured in various ways, such as a conveyor belt, a load-bearing bridge (LBS), a plate that moves or rotates mechanically, and so on.

In the first movement section E1, the second feeder drive section F2 can move the fourth pickup section P4 to the negative electrode first-direction transfer machine 40n and can move the third pickup section P3 to the negative electrode alignment table 62 of the second stacker 60b. The fourth pickup section P4 can pick up the negative electrode 5n on the negative electrode first-direction transfer machine 40n.

[0121] Fig. Figure 10 is a view that represents a plant layout 100 according to one embodiment.

[0122] The plant layout 100 according to one embodiment is a structure in which devices such as the unwinders 20p and 20n, the reel changers 10p and 10n, the notching machines 31p and 31n, the cutters 32p and 32n, the first-direction forwarding machines 40p and 40n, the second-direction forwarding machines 50p and 50n, the stackers 60a and 60b and so on, which are arranged in a secondary battery manufacturing plant, are arranged.

[0123] The plant layout 100 according to one embodiment may include the following: the multitude of complex plants 1, which are arranged with reference to Fig. 1 to Fig.9 are described; a plurality of first carriers 110 configured to convey the electrode assembly 6 produced by the first stacker 60a and the second stacker 60b of the complex system 1 in the first direction D1; and a second carrier 120 configured to receive the electrode assembly 6 conveyed by the plurality of first carriers 110 and to convey the electrode assembly 6 in the second direction D2.

[0124] Complex system 1 is a device in which various devices (for example, the roll changers 10p and 10n, the unwinders 20p and 20n, the notching machines 31p and 31n, the cutters 32p and 32n, the first-direction transfer machines 40p and 40n, the second-direction transfer machines 50p and 50n, and the stackers 60a and 60b) required for the manufacture of the electrode assembly 6 are arranged such that the various devices are able to be operated in a single sequence. Complex system 1 is designed so that the multitude of different devices occupies a minimal area.

[0125] The first carrier 110 can convey the electrode assembly 6 produced by the complex system 1. The second carrier 120 can convey the electrode assembly 6 received by the first carrier 110. The first carrier 110 and the second carrier 120 can be configured as a conveyor belt, a load carrier system (LCS), or various other conveying devices. The first carrier 110 can be arranged in the first direction D1. The first carrier 110 can be arranged such that one first carrier 110 is located in the first stacker 60a and one first carrier 110 is located in the second stacker 60b. That is, two first carriers 110 can be arranged in a complex system 1. The first carrier 110 can receive the electrode assembly 6 produced in the stacker of the complex system 1 and can convey the electrode assembly 6 to the second carrier 120.The second carrier 120 can receive the electrode assembly 6 from the plurality of first carriers 110 and can guide the electrode assembly 6 further. The second carrier 120 can be arranged in the second direction D2.

[0126] The multiple complex units 1 can be arranged such that the multiple first supports 110 are connected to the second support 120. Within the multiple complex units 1, the stackers 60a and 60b can be positioned close to the second support 120, and the unwinder can be located far from the second support 120. The multiple notching and stacking units can be arranged so that they are spaced apart from each other at a predetermined distance W. That is, the multiple complex units 1 can be arranged as a comb extending from the second support 120 to one side. Furthermore, the multiple complex units 1 can be arranged as a comb extending around the second support 120 on both sides. In this configuration, the manufactured electrode assembly 6 can be discharged from both sides towards the second support 120.

[0127] The multitude of complex systems 1 can be arranged such that they are spaced apart from each other in the second direction D2. The multitude of complex systems 1 can be arranged such that they are spaced apart from each other along the second support 120, which extends in the second direction D2, by a predetermined distance W. The distance W between the multitude of complex systems 1 can be determined as a distance sufficient for the worker to enter between the stackers and perform work. The worker can enter the space between the multitude of complex systems 1. The worker can enter along the first direction D1 and has access to the roll changers 10p and 10n, the unwinders 20p and 20n, the notching machines 31p and 31n, the cutters 32p and 32n, the first-direction forwarding machines 40p and 40n, the second-direction forwarding machines 50p and 50n, the stackers 60a and 60b and the first carriers 110.Since the numerous devices in the complex system 1 are arranged in the first direction D1, the worker can enter along this direction and access the devices. In the manufacturing process of electrode assembly 6, all materials or the worker can move along the first direction D1, while the electrode assembly 6 moves along the second direction D2, thus simplifying the factory workflow.

[0128] The plant layout 100 according to one embodiment can further include a roll feeder unit 130 configured to feed the positive electrode film roll 2p or the negative electrode film roll 2n to the plurality of complex plants 1 and which is autonomously driven. The roll feeder unit 130 can feed a roll to the positive electrode roll changer 10p or the negative electrode roll changer 10n while moving in a state in which the positive electrode film roll 2p or the negative electrode film roll 2n is loaded into the roll feeder unit 130. Since the roll changers of the plurality of complex plants 1 are positioned next to each other, a flow line in which the roll feeder unit 130 accesses the roll changers can be simplified in the plant layout 100.Since a certain amount of time is required for the complex system 1 to use up the roll, a roll feeder unit 130 can feed the roll to the multitude of complex systems 1. Because the flow path along which the roll feeder unit 130 reaches the multitude of complex systems 1 is simple, the movement time can also be minimized. Therefore, compared to the number of complex systems 1, the number of roll feeder units 130 in the system layout 100 according to one embodiment can be relatively small. Consequently, the space occupied by the roll feeder unit 130 and the space required for the roll feeder unit 130 to move within the factory can be minimized.
