[0109] The present disclosure will now be described in detail (with reference to the accompanying drawings). However, this is merely exemplary and the present disclosure is not limited to the specific embodiments described herein.

[0110] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0111] Figure 1 This is a diagram illustrating a composite device 1 according to one embodiment.

[0112] The composite equipment 1 can perform the following processes in one process: a grooving process, forming tabs on the electrode sheet and cutting to form an electrode; and a stacking process, stacking the negative electrode 5n, the separator 7 and the positive electrode 5p to form an electrode assembly 6.

[0113] According to one embodiment, the composite apparatus 1 may include: a positive electrode manufacturing machine 30p, which forms a positive electrode 5p by forming tabs on a positive electrode sheet 3p traveling along a first direction D1 and then drying and cutting it; a negative electrode manufacturing machine 30n, which forms a negative electrode 5n by forming tabs on a negative electrode sheet 3n traveling along the first direction D1 and then drying and cutting it, and is arranged parallel to the positive electrode manufacturing machine 30p; a positive electrode first direction conveyor 40p, which conveys the positive electrode 5p output from the positive electrode manufacturing machine 30p along the first direction D1; a negative electrode first direction conveyor 40n, which conveys the negative electrode 5n output from the negative electrode manufacturing machine 30n along the first direction D1; and one or more first stackers 60a, centered on the positive electrode first direction conveyor 40p and located in the negative electrode first direction conveyor... On the opposite side of the positive electrode 5p, the separator 7 and the negative electrode 5n are stacked to form an electrode assembly 6; one or more second stackers 60b are located on the opposite side of the positive electrode first direction transmitter 40p with the negative electrode first direction transmitter 40n as the center, and the positive electrode 5p, the separator 7 and the negative electrode 5n are stacked to form an electrode assembly 6; one or more positive electrode second direction transmitters 50p transmit the positive electrode 5p transmitted by the positive electrode first direction transmitter 40p along the second direction and supply it to the first stacker 60a and the second stacker 60b; and one or more negative electrode second direction transmitters 50n transmit the negative electrode 5n transmitted by the negative electrode first direction transmitter 40n along the second direction and supply it to the first stacker 60a and the second stacker 60b.

[0114] According to one embodiment, the composite apparatus 1 may further include: a positive electrode unwinder 20p, which unwinds the positive electrode coil 2p along a first direction D1 to supply the positive electrode 3p to the positive electrode manufacturing machine 30p; and a negative electrode unwinder 20n, which unwinds the negative electrode coil 2n along the first direction D1 to supply the negative electrode 3n to the negative electrode manufacturing machine 30n.

[0115] According to one embodiment, the composite device 1 may further include: a positive electrode roll changer 10p, which discharges the depleted positive electrode roll 2p and replaces it with a prepared new positive electrode roll 2p when the positive electrode unwinder 20p is depleted; and a negative electrode roll changer 10n, which discharges the depleted negative electrode roll 2n and replaces it with a prepared new negative electrode roll 2n when the negative electrode unwinder 20n is depleted.

[0116] In the composite equipment 1, the positive electrode wire connected by the positive electrode winding changer 10p, the positive electrode unwinder 20p, the positive electrode manufacturing machine 30p and the positive electrode first direction conveyor 40p and the negative electrode wire connected by the negative electrode winding changer 10n, the negative electrode unwinder 20n, the negative electrode manufacturing machine 30n and the negative electrode first direction conveyor 40n can be arranged parallel to each other along the first direction D1.

[0117] The positive electrode first direction conveyor 40p and the negative electrode first direction conveyor 40n may include a conveyor belt, a linear motion system (LMS), and other devices capable of conveying electrodes. Positive electrodes 5p and negative electrodes 5n manufactured by the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n can be directly supplied to the positive electrode first direction conveyor 40p and the negative electrode first direction conveyor 40n. The positive electrode first direction conveyor 40p and the negative electrode first direction conveyor 40n can convey the positive electrode 5p and the negative electrode 5n along the first direction D1. The positive electrode 5p and the negative electrode 5n conveyed along the first direction D1 can be supplied to the first stacker 60a and the second stacker 60b through the positive electrode second direction conveyor 50p and the negative electrode second direction conveyor 50n.

[0118] Since the positive electrode 5p and negative electrode 5n are not contained in the cassette after manufacturing, damage that may occur during the process of containing and removing them from the cassette can be avoided. For example, the positive electrode 5p may suffer various damages such as bending, tearing, or cracking of the active material due to the edge of the positive electrode 5p colliding with the cassette. The positive electrode 5p and negative electrode 5n can be moved via the positive electrode first direction conveyor 40p and the negative electrode first direction conveyor 40n and supplied to the stacker via the positive electrode second direction conveyor 50 and the negative electrode second direction conveyor 50n. Therefore, damage that may occur to the positive electrode 5p and negative electrode 5n during the transfer process can be minimized.

[0119] The first stacker 60a and the second stacker 60b can be configured on the outer sides of the positive and negative electrodes. Therefore, the operator can perform the required operations on the first stacker 60a and the second stacker 60b on the outer sides of the positive and negative electrodes. Specifically, the first stacker 60a can be configured on the opposite side of the negative first-direction transmitter 40n, centered on the positive first-direction transmitter 40p. The second stacker 60b can be configured on the opposite side of the positive first-direction transmitter 40p, centered on the negative first-direction transmitter 40n. Alternatively, the positive first-direction transmitter 40p and the negative first-direction transmitter 40n can be configured between the first stacker 60a and the second stacker 60b.

[0120] Since the first stacker 60a and the second stacker 60b are not located between the positive and negative electrode lines, the operator can easily access them. For automated equipment requiring maintenance (positive electrode uncoiler 20p, negative electrode uncoiler 20n, positive electrode winding changer 10p, negative electrode winding changer 10n, positive electrode manufacturing machine 30p, negative electrode manufacturing machine 30n, first direction conveyors 40p and 40n, second direction conveyors 50p and 50n, first stacker 60a, and second stacker 60b), the operator can approach from the outside of the positive and negative electrode lines. Only the positive electrode bridging portion 70p and the negative electrode bridging portion 70n are located between the positive and negative electrode lines, so the distance between them can be minimized. That is, the left-right dimensions (second direction D2 length) of the composite device 1 can be minimized. Therefore, the operator's movement path from the outside of the positive electrode line to the outside of the negative electrode line can be minimized. Furthermore, the area occupied by the composite equipment 1 can be reduced, and the area of ​​the entire manufacturing plant can be reduced. That is, the space of the secondary battery manufacturing plant can be utilized effectively.

[0121] The positive electrode second direction transmitter 50p may include: a positive electrode bridging section 70p, located between the positive electrode first direction transmitter 40p and the negative electrode first direction transmitter 40n and used to place a positive electrode 5p; a first positive electrode supplier 50p1, which supplies the positive electrode 5p on the positive electrode first direction transmitter 40p to the first stacker 60a and moves another positive electrode 5p on the positive electrode first direction transmitter 40p to the positive electrode bridging section 70p; and a second positive electrode supplier 50p2, which supplies the positive electrode 5p on the positive electrode bridging section 70p to the second stacker 60b.

[0122] The negative electrode second direction transmitter 50n may include: a negative electrode bridging section 70n, located between the positive electrode first direction transmitter 40p and the negative electrode first direction transmitter 40n and used to place a negative electrode 5n; a first negative electrode supplier 50n1, which supplies the negative electrode 5n on the negative electrode first direction transmitter 40n to the second stacker 60b and moves another negative electrode 5n on the negative electrode first direction transmitter 40n to the negative electrode bridging section 70n; and a second negative electrode supplier 50n2, which supplies the negative electrode 5n on the negative electrode bridging section 70n to the first stacker 60a.

[0123] The first positive electrode supplier 50p1 and the second positive electrode supplier 50p2 can be arranged side-by-side along a second direction D2 perpendicular to the first direction D1. The first positive electrode supplier 50p1 can supply positive electrode 5p to the first stacker 60a, and the second positive electrode supplier 50p2 can supply positive electrode 5p to the second stacker 60b. The first negative electrode supplier 50n1 and the second negative electrode supplier 50n2 can be arranged side-by-side along a second direction D2 perpendicular to the first direction D1. The first negative electrode supplier 50n1 can supply negative electrode 5n to the second stacker 60b, and the second negative electrode supplier 50n2 can supply negative electrode 5n to the first stacker 60a. The first positive electrode supplier 50p1 and the second negative electrode supplier 50n2 can be configured on the positive electrode first direction transmitter 40p. The second positive electrode supplier 50p2 and the first negative electrode supplier 50n1 can be configured on the negative electrode first direction transmitter 40n. Figure 1 It can be confirmed that the first positive electrode supplier 50p1 and the second positive electrode supplier 50p2 are configured close to the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n, while the first negative electrode supplier 50n1 and the second negative electrode supplier 50n2 are configured far from the negative electrode manufacturing machine 30n and the positive electrode manufacturing machine 30p. Figure 1 Unlike other devices, the first positive electrode supply 50p1 and the second positive electrode supply 50p2 can be configured to be far away from the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n, while the first negative electrode supply 50n1 and the second negative electrode supply 50n2 can be configured to be close to the negative electrode manufacturing machine 30n and the positive electrode manufacturing machine 30p.

[0124] The positive electrode manufacturing machine 30p, the positive electrode first direction conveyor 40p, the positive electrode supply 50p1, 50p2, the first stacker 60a, the negative electrode manufacturing machine 30n, the negative electrode first direction conveyor 40n, the negative electrode supply 50n1, 50n2 and the second stacker 60b are all organically linked and can be operated as a single device.

The negative electrode 5n generated by the negative electrode cutter 32n cutting the negative electrode sheet 3n can be output to the negative electrode first direction transmitter 40n.

[0143] Because the grooving devices 31p and 31n, the dryers 33p and 33n, and the cutters 32p and 32n are continuously arranged in a single composite device, separate units for each grooving, drying, and cutting process can be eliminated, thus minimizing the factory area. Furthermore, when grooving, drying, and cutting processes are performed in individual units, damage such as serpentine movement, unwinding, and detachment of the electrode sheets can occur during the unwinding and rewinding processes when transferring the electrode sheets between units.

[0153] In the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n, the order of dryers 33p and 33n, grooving machines 31p and 31n, and cutters 32p and 32n can be changed. For example, as Figures 2 to 5 As shown, the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n can be configured in the order of grooving machine 31p, 31n, dryer 33p, 33n, and cutter 32p, 32n. Alternatively, as... Figures 6 to 8 As shown, the positive electrode manufacturing machine 30p and the negative electrode manufacturing machine 30n can be configured in the order of dryers 33p and 33n, grooving machines 31p and 31n, and cutters 32p and 32n. Considering the advantages and disadvantages of each sequence described below, the user can choose which sequence to use based on the characteristics of the manufacturing process.

[0154] Reference Figures 2 to 5 The positive electrode manufacturing machine 30p and negative electrode manufacturing machine 30n described herein can perform drying after grooving. For example... Figures 6 to 8 In the structure shown, when the electrode sheets (positive electrode 3p, negative electrode 3n) are heated by dryers 33p and 33n before grooving, the increased temperature of the current collector may alter the physical properties of the metal affecting the grooving process. For example, the dimensions of the electrode sheets (positive electrode 3p, negative electrode 3n) may change as the temperature increases. Furthermore, the contact of the high-temperature electrode sheets (positive electrode 3p, negative electrode 3n) with the molds of the grooving machines 31p and 31n may cause a temperature rise in the molds, affecting the grooving quality. Therefore, it is necessary to consider the temperature variation of the current collector during grooving. Conversely, as... Figures 2 to 5 The structure shown does not require consideration of the temperature change of the collector during the grooving process if drying is performed after grooving.

[0155] In addition, such as Figures 2 to 5 The structure shown, if dried after grooving, may suffer defects such as bent or damaged tabs during the travel of the electrode sheets (positive electrode 3p, negative electrode 3n) with tabs (positive tab 4p, negative tab 4n). This defect can be prevented by minimizing the travel distance after grooving.

[0156] Reference Figures 6 to 8The positive electrode manufacturing machine 30p and negative electrode manufacturing machine 30n described herein can be grooved after drying. For example... Figures 2 to 5 As shown in the structure, when the electrode tabs (positive electrode tab 4p, negative electrode tab 4n) are formed on the electrode plates (positive electrode plate 3p, negative electrode plate 3n) by the slotters 31p and 31n and then dried, the electrode plates (positive electrode plate 3p, negative electrode plate 3n) may be bent or damaged during their movement toward the dryers 33p and 33n due to various reasons such as vibration of the electrode tabs (positive electrode tab 4p, negative electrode tab 4n), contact with the guide rollers, and air resistance.

[0157] On the contrary, such as Figures 6 to 8 The structure shown can minimize damage to the tabs (positive tab 4p, negative tab 4n) by grooving after drying. Therefore, the quality of the electrode plates (positive plate 3p, negative plate 3n) can be improved.

[0158] In addition, such as Figures 6 to 8 In the structure shown, if grooving is performed after drying, the electrode temperature rises during the drying process, and heat may be transferred to the grooving machines 31p and 31n during grooving. Therefore, the temperature rise of the mold in the grooving machines 31p and 31n may affect the grooving quality. By adding a cooling section at the rear end of the dryers 33p and 33n to reduce the electrode temperature, the temperature rise of the mold in the grooving machines 31p and 31n can be prevented.

[0159] See you again Figures 2 to 5 .

[0160] The positive electrode first-direction transmitter 40p can transmit the positive electrode 5p along the first direction D1. The negative electrode first-direction transmitter 40n can transmit the negative electrode 5n along the first direction D1.

The first positive electrode supplier 50p1 can pick up another positive electrode 5p conveyed via the positive electrode first direction conveyor 40p and move it to a positive electrode bridging section 70p. The positive electrode 5p moved to the positive electrode bridging section 70p can be supplied to a second stacker 60b via a second positive electrode supplier 50p2. The second positive electrode supplier 50p2 can supply the positive electrode 5p to the positive electrode alignment stage 61 of the second stacker 60b.

[0162] A first negative electrode supplier 50n1 can be configured on a negative electrode first direction conveyor 40n. The first negative electrode supplier 50n1 can pick up a negative electrode 5n conveyed via the negative electrode first direction conveyor 40n and supply it to a second stacker 60b. The first negative electrode supplier 50n1 can supply the negative electrode 5n to the negative electrode alignment stage 62 of the second stacker 60b.

The negative electrode 5n moved to the negative electrode bridging section 70n can be supplied to a first stacker 60a via a second negative electrode supplier 50n2. The second negative electrode supplier 50n2 can supply the negative electrode 5n to the negative electrode alignment stage 62 of the first stacker 60a.

[0163] Figure 9 This is a diagram illustrating a stacker according to one embodiment of a rotation method.

[0164] The first stacker 60a and the second stacker 60b can be configured in a rotatable manner. Rotational configuration refers to the rotary stacking stage 64a, used for stacking the positive electrode 5p, the separator 7, and the negative electrode 5n, reciprocating around the rotation axis RA0 by a predetermined angle. The rotary stacker may include a positive electrode alignment stage 61 for aligning the positive electrode 5p, a negative electrode alignment stage 62 for aligning the negative electrode 5n, a first rotary pickup section 63a for picking up the positive electrode 5p from the positive electrode alignment stage 61 and moving it to the rotary stacking stage 64a, a second rotary pickup section 63b for picking up the negative electrode 5n from the negative electrode alignment stage 62 and moving it to the rotary stacking stage 64a, a rotary stacking stage 64a that reciprocates around the rotation axis RA0 by a predetermined angle and whose upper surface is used for stacking the positive electrode 5p, the separator 7, and the negative electrode 5n, and a separator supply section 65 that outputs the separator 7 to the upper surface of the rotary stacking stage 64a.

[0165] The rotation axis RA0 of the rotary stacking stage 64a can be located in the direction of the lower surface of the rotary stacking stage 64a.

[0166] The first rotary pickup unit 63a can rotate around a rotation axis RA1 to reciprocate between the positive electrode alignment stage 61 and the rotary stacking stage 64a. The rotation axis RA1 of the first rotary pickup unit 63a can be located in the direction of the upper surface of the positive electrode alignment stage 61.

The length of the second rotary pickup unit 63b can be adjusted radially along the rotation axis RA2 to pick up and release the negative electrode 5n.

[0167] In the first stacking section G1, the diaphragm supply unit 65 can output the diaphragm 7 to the rotating stacking stage 64a. The rotating stacking stage 64a can rotate by a predetermined angle so that its upper surface faces the first rotating pickup unit 63a. When the rotating stacking stage 64a rotates, the diaphragm 7 can cover the rotating stacking stage 64a (or the negative electrode 5n). The first rotating pickup unit 63a can place the positive electrode 5p on the diaphragm 7 on the upper surface of the rotating stacking stage 64a. The second rotating pickup unit 63b can pick up the negative electrode 5n on the negative electrode alignment stage 62.

[0168] In the second stacking section G2, the diaphragm supply unit 65 can output the diaphragm 7 to the rotating stacking stage 64a. The rotating stacking stage 64a can rotate by a predetermined angle so that its upper surface faces the second rotating pickup unit 63b. When the rotating stacking stage 64a rotates, the diaphragm 7 can cover the positive electrode 5p (or the rotating stacking stage 64a). The second rotating pickup unit 63b can place the negative electrode 5n on the diaphragm 7 on the upper surface of the rotating stacking stage 64a. The first rotating pickup unit 63a can pick up the positive electrode 5p on the positive electrode alignment stage 61. The negative electrode suppliers 50n1 and 50n2 can supply the negative electrode 5n to the negative electrode alignment stage 62.

[0169] It can be determined that the order of the first stacking interval G1 and the second stacking interval G2 corresponds to the operating order of the positive electrode supplies 50p1 and 50p2 and the negative electrode supplies 50n1 and 50n2.

[0170] A rotary stacker can form an electrode assembly 6, consisting of a positive electrode 5p, a separator 7, and a negative electrode 5n, on the upper surface of a rotary stacking stage 64a by repeating a first stacking interval G1 and a second stacking interval G2. The rotary stacker can output the electrode assembly 6 formed by repeating the first stacking interval G1 and the second stacking interval G2 a predetermined number of times. The electrode assembly 6 can be removed from the rotary stacker using a device employing a robotic arm and a gripper.

[0171] Figure 10 This is a diagram illustrating a stacker according to one embodiment of a fixing method.

[0172] The first stacker 60a and the second stacker 60b can be configured in a fixed manner. A fixed manner means that the fixed stacking platform 64b used for stacking the positive electrode 5p, the separator 7, and the negative electrode 5n does not move. The fixed stacker may include a positive electrode alignment platform 61 for aligning the positive electrode 5p, a negative electrode alignment platform 62 for aligning the negative electrode 5n, a third rotary pickup unit 63c for picking up the positive electrode 5p from the positive electrode alignment platform 61 and moving it to the fixed stacking platform 64b, a fourth rotary pickup unit 63d for picking up the negative electrode 5n from the negative electrode alignment platform 62 and moving it to the fixed stacking platform 64b, a fixed stacking platform 64b on its upper surface where the positive electrode 5p, the separator 7, and the negative electrode 5n are stacked, a separator supply unit 65 for outputting the separator 7 to the upper surface of the fixed stacking platform 64b, and a separator guide unit 66 for guiding the separator 7 to cover the positive electrode 5p or the negative electrode 5n.

[0173] The third rotary pickup unit 63c can rotate around the rotation axis RA3 to reciprocate between the positive electrode alignment stage 61 and the fixed stacking stage 64b. The rotation axis RA3 of the third rotary pickup unit 63c can be located in the direction of the lower surface of the positive electrode alignment stage 61. The length of the third rotary pickup unit 63c can be adjusted radially along the rotation axis RA3 to pick up and release the positive electrode 5p. The fourth rotary pickup unit 63d can rotate around the rotation axis RA4 to reciprocate between the negative electrode alignment stage 62 and the fixed stacking stage 64b. The rotation axis RA4 of the fourth rotary pickup unit 63d can be located in the direction of the lower surface of the negative electrode alignment stage 62. The length of the fourth rotary pickup unit 63d can be adjusted radially along the rotation axis RA4 to pick up and release the negative electrode 5n.

[0174] The diaphragm guide 66 may include a pair of rollers. The diaphragm 7 can pass between the pair of rollers. The diaphragm guide 66 can rotate the position of the pair of rollers about a rotation axis RA5. The rotation axis RA5 of the diaphragm guide 66 can be located in the direction of the lower surface of the alignment stage. The diaphragm guide 66 can guide the diaphragm 7 to cover the positive electrode 5p or the negative electrode 5n by reciprocating the pair of rollers at a predetermined angle along the positive electrode alignment stage 61 direction and the negative electrode alignment stage 62 direction.

[0175] In the third stacking section, the diaphragm guide 66 guides the diaphragm 7 to cover the fixed stacking stage 64b (or the positive electrode 5p) by moving a pair of rollers along the positive electrode alignment stage 61. The fourth rotary pickup 63d can place the negative electrode 5n onto the diaphragm 7 on the upper surface of the fixed stacking stage 64b. The third rotary pickup 63c can pick up the positive electrode 5p on the positive electrode alignment stage 61. The negative electrode suppliers 50n1 and 50n2 can supply the negative electrode 5n to the negative electrode alignment stage 62.

[0176] In the fourth stacking section, the diaphragm guide 66 guides the diaphragm 7 to cover the negative electrode 5n (or the fixed stacking stage 64b) by moving a pair of rollers along the direction of the negative electrode alignment stage 62. The third rotary pickup 63c can place the positive electrode 5p onto the diaphragm 7 on the upper surface of the fixed stacking stage 64b. The fourth rotary pickup 63d can pick up the negative electrode 5n on the negative electrode alignment stage 62. The positive electrode suppliers 50p1 and 50p2 can supply the positive electrode 5p to the positive electrode alignment stage 61.

[0177] It can be determined that the order of the third and fourth stacking intervals corresponds to the operating order of the positive electrode supplies 50p1 and 50p2 and the negative electrode supplies 50n1 and 50n2.

[0178] A fixed-mode stacker can form an electrode assembly 6, consisting of a positive electrode 5p, a separator 7, and a negative electrode 5n, on the upper surface of a fixed stacking stage 64b by repeating a third and fourth stacking interval. The fixed-mode stacker can output the electrode assembly 6 formed by repeating the third and fourth stacking intervals a predetermined number of times. The electrode assembly 6 can be removed from the fixed-mode stacker using a device employing a robotic arm and a gripper.

Figure 12 The first negative electrode supplier 50n1 and the second negative electrode supplier 50n2 are shown along the direction from the negative electrode unwinding machine 20n to the negative electrode manufacturing machine. (See also...) Figure 2 and Figure 3 .

[0180] Positive electrode suppliers 50p1 and 50p2 are means for picking up the positive electrode 5p conveyed by the positive electrode first direction transmitter 40p and supplying it to the stacker.

Negative electrode suppliers 50n1 and 50n2 may include a first negative electrode supplier 50n1 and a second negative electrode supplier 50n2.

[0181] The first positive electrode supplier 50p1 and the first negative electrode supplier 50n1 can operate in a similar sequence. The first positive electrode supplier 50p1 can pick up the positive electrode 5p from the positive electrode first direction transmitter 40p and supply it directly to the first stacker 60a. The first negative electrode supplier 50n1 can pick up the negative electrode 5n from the negative electrode first direction transmitter 40n and supply it directly to the second stacker 60b.

[0182] The first positive electrode supply 50p1 may include a first pickup part P1 that picks up the positive electrode 5p on the positive electrode first direction transmitter 40p and supplies it to the first stacker 60a, a second pickup part P2 that picks up the positive electrode 5p on the positive electrode first direction transmitter 40p and supplies it to the positive electrode bridging part 70p, and a first supply drive part F1 that moves the first pickup part P1 and the second pickup part P2 simultaneously along a second direction D2 that is perpendicular to the first direction D1.

[0183] The first negative electrode supplier 50n1 may include a third pickup unit P3 that picks up the negative electrode 5n on the negative electrode first direction transmitter 40n and supplies it to the first stacker 60a, a fourth pickup unit P4 that picks up the negative electrode 5n on the negative electrode first direction transmitter 40n and moves it to the negative electrode bridging unit 70n, and a second supply drive unit F2 that moves the third pickup unit P3 and the fourth pickup unit P4 simultaneously along a second direction D2 that is perpendicular to the first direction D1.

[0184] The second positive electrode supply 50p2 and the second negative electrode supply 50n2 can operate in a similar sequence. The second positive electrode supply 50p2 can pick up the positive electrode of the first positive electrode supply 50p1 and move it to the positive electrode of the positive electrode bridging section 70p and supply it to the second stacker 60b. The second negative electrode supply 50n2 can pick up the negative electrode of the first negative electrode supply 50n1 and move it to the negative electrode of the negative electrode bridging section 70n and supply it to the first stacker 60a.

[0185] According to one embodiment, the composite device 1 may further include: a negative electrode suspension stage 80n, spaced apart from the upper part of the positive electrode first direction transmitter 40p, and used to place the negative electrode 5n; and a positive electrode suspension stage 80p, spaced apart from the upper part of the negative electrode first direction transmitter 40n, and used to place the positive electrode 5p.

[0186] The positive electrode suspension platform 80p provides space for placing the positive electrode 5p in the second positive electrode supplier 50p2. The negative electrode suspension platform 80n provides space for placing the negative electrode 5n in the second negative electrode supplier 50n2. Because the positive electrode suspension platform 80p is spaced apart from the upper part of the negative electrode first direction transmitter 40n, it does not obstruct the transmission of the negative electrode 5n by the negative electrode first direction transmitter 40n. Similarly, because the negative electrode suspension platform 80n is spaced apart from the upper part of the positive electrode first direction transmitter 40p, it does not obstruct the transmission of the positive electrode 5p by the positive electrode first direction transmitter 40p.

[0187] The second positive electrode supply 50p2 may include: a fifth pickup unit P5, which picks up the positive electrode 5p on the positive electrode bridging unit 70p and moves it to the positive electrode suspension stage 80p; a sixth pickup unit P6, which picks up the positive electrode 5p on the positive electrode suspension stage 80p and supplies it to the second stacker 60b; and a third supply drive unit F3, which moves the fifth pickup unit P5 and the sixth pickup unit P6 simultaneously along a second direction D2 that is perpendicular to the first direction D1.

[0188] The second negative electrode supply 50n2 may include: a seventh pickup unit P7, which picks up the negative electrode 5n on the negative electrode bridging unit 70n and moves it to the negative electrode suspension stage 80n; an eighth pickup unit P8, which picks up the negative electrode 5n on the negative electrode suspension stage 80n and supplies it to the first stacker 60a; and a fourth supply drive unit F4, which moves the seventh pickup unit P7 and the eighth pickup unit P8 simultaneously along a second direction D2 that is perpendicular to the first direction D1.

[0189] The first positive electrode supplier 50p1, the first negative electrode supplier 50n1, the second positive electrode supplier 50p2, and the second negative electrode supplier 50n2 can all include two pickup units and one supply drive unit. The supply drive unit can cause the two pickup units to move simultaneously along the second direction D2. The supply drive unit can also cause the two pickup units to reciprocate along the second direction D2. When the two pickup units move along one side or the other side of the second direction D2 via the supply drive unit, a pickup or release action can be performed. Either one of the two pickup units can perform a pickup action, and the other can perform a release action. Alternatively, the two pickup units can perform pickup actions or release actions simultaneously. All four suppliers have the same structure with two pickup units and one supply drive unit. Therefore, it is convenient to control multiple suppliers simultaneously and is easy to maintain. The positive electrode suspension stage 80p and the negative electrode suspension stage 80n can be mounted on transmitters with different polarities to use suppliers with the same structure.

[0190] Picking up an electrode from a worktable or conveyor is the action of lifting it. Releasing an electrode from the pick-up unit is the action of placing the lifted electrode at a predetermined position. The pick-up unit can pick up or release electrodes using methods such as vacuum suction, grippers, electromagnetic force, or adhesive force. The length of the pick-up unit can be adjusted in a third direction D3, perpendicular to the first direction D1 and the second direction D2, to pick up the electrode. The second positive electrode supply 50p2 and the second negative electrode supply 50n2 can perform the length adjustment of the pick-up unit to pick up the electrode on the suspension stage. The action of the supply drive unit to reciprocate the pick-up unit along the second direction D2 and the length adjustment action of the pick-up unit can be performed by various means such as sliders, motors, gears, and robotic arms.

[0191] The composite device may further include: a negative electrode separator 90n, located between the positive electrode first direction conveyor 40p and the negative electrode suspension stage 80n, extending along the path of the second negative electrode supplier 50n2 to move the negative electrode 5n, to prevent negative electrode particles falling from the negative electrode 5n from falling onto the positive electrode first direction conveyor 40p; and a positive electrode separator 90p, located between the negative electrode first direction conveyor 40n and the positive electrode suspension stage 80p, extending along the path of the second positive electrode supplier 50p2 to move the positive electrode 5p, to prevent positive electrode particles falling from the positive electrode 5p from falling onto the negative electrode first direction conveyor 40n.

[0192] The negative electrode separator 90n prevents foreign matter, such as negative electrode active material, from flowing into the positive electrode first direction transmitter 40p during the movement of the negative electrode 5n towards the upper part of the positive electrode first direction transmitter 40p. The negative electrode separator 90n can be located between the transmission path of the positive electrode 5p and the transmission path of the negative electrode 5n to separate the space.

[0193] The negative electrode separator 90n can be formed in the shape of a plate. The width of the negative electrode separator 90n can be formed to be greater than the width of the negative electrode suspension stage 80n. The negative electrode separator 90n can be formed elongated along the moving path of the second negative electrode supplier 50n2. The negative electrode separator 90n can be located between the positive electrode first direction transmitter 40p and the negative electrode suspension stage 80n. The negative electrode separator 90n can be sufficiently separated from the positive electrode first direction transmitter 40p to avoid obstructing the movement of the positive electrode 5p on the positive electrode first direction transmitter 40p.

[0194] During the process of the second negative electrode supplier 50n2 picking up and moving the negative electrode 5n, a portion of the compound layer of the negative electrode 5n may separate and fall off. If a portion of the fallen compound layer comes into contact with the positive electrode 5p or mixes with the positive electrode first direction transmitter 40p, the function of the electrode assembly 6 may degrade. The negative electrode separator 90n prevents foreign matter from coming into contact with the positive electrode 5p during the process of the second negative electrode supplier 50n2 picking up and moving the negative electrode 5n.

[0195] The positive electrode separator 90p prevents foreign materials, such as positive electrode active material, from falling from the positive electrode 5p into the negative electrode first direction transmitter 40n during the movement of the positive electrode 5p to the upper part of the negative electrode first direction transmitter 40n. The positive electrode separator 90p can be located between the transmission path of the positive electrode 5p and the transmission path of the negative electrode 5n to separate the space.

[0196] The positive electrode separator 90p can be formed in the shape of a plate. The width of the positive electrode separator 90p can be greater than the width of the positive electrode suspension stage 80p. The positive electrode separator 90p can be formed elongated along the moving path of the second positive electrode supplier 50p2. The positive electrode separator 90p can be located between the negative electrode first direction transmitter 40n and the positive electrode suspension stage 80p. The positive electrode separator 90p can be sufficiently separated from the negative electrode first direction transmitter 40n to avoid obstructing the movement of the negative electrode 5n on the negative electrode first direction transmitter 40n.

[0197] During the process of the second positive electrode supplier 50p2 picking up and moving the positive electrode 5p, a portion of the binder layer of the positive electrode 5p may separate and fall off. If a portion of the fallen binder layer comes into contact with the negative electrode 5n or mixes with the negative electrode first direction transmitter 40n, the function of the electrode assembly 6 may be degraded. The positive electrode separator 90p prevents foreign matter from coming into contact with the negative electrode 5n during the process of the second positive electrode supplier 50p2 picking up and moving the positive electrode 5p.

[0198] The positive bridging part 70p can move the positive electrode 5p of the first positive electrode supply 50p1 to the position picked up by the second positive electrode supply 50p2, and the negative bridging part 70n can move the negative electrode 5n of the first negative electrode supply 50n1 to the position picked up by the second negative electrode supply 50n2.

[0199] The positive bridging section 70p and the negative bridging section 70n can be implemented using a conveyor belt, LMS, a mechanical reciprocating or rotating plate, and various other methods. The positive bridging section 70p can move the positive electrode 5p, which is located on one side of the first positive electrode supplier 50p1, to the other side of the positive bridging section 70p. The second positive electrode supplier 50p2 can pick up the positive electrode 5p that has moved to the other side of the positive bridging section 70p. The negative bridging section 70n can move the negative electrode 5n, which is located on one side of the first negative electrode supplier 50n1, to the other side of the negative bridging section 70n. The second negative electrode supplier 50n2 can pick up the negative electrode 5n that has moved to the other side of the negative bridging section 70n. The positive bridging part 70p can move the positive electrode 5p along the direction of the negative electrode first direction transmitter 40n, and the negative bridging part 70n can move the negative electrode 5n along the direction of the positive electrode first direction transmitter 40p. That is, the positive bridging part 70p and the negative bridging part 70n can move either the positive electrode 5p or the negative electrode 5n along the second direction D2.

[0200] The first positive electrode supply 50p1, the second positive electrode supply 50p2, the first negative electrode supply 50n1, and the second negative electrode supply 50n2 can repeat the operations performed in the first motion interval E1 and the operations performed in the second motion interval E2, and supply electrodes to the stacker.

[0201] The first positive electrode supplier 50p1, the positive electrode bridging part 70p, and the second positive electrode supplier 50p2 can be arranged on the same line along the second direction D2. The first negative electrode supplier 50n1, the negative electrode bridging part 70n, and the second negative electrode supplier 50n2 can also be arranged on the same line along the second direction D2. The positive electrode 5p transmitted by the positive electrode first direction transmitter 40p can pass through the first positive electrode supplier 50p1, the positive electrode bridging part 70p, and the second positive electrode supplier 50p2 through the negative electrode first direction transmitter 40n and be supplied to the second stacker 60b. The negative electrode 5n transmitted by the negative electrode first direction transmitter 40n can pass through the first negative electrode supplier 50n1, the negative electrode bridging part 70n, and the second negative electrode supplier 50n2 through the positive electrode first direction transmitter 40p and be supplied to the first stacker 60a.

[0202] Multiple first stackers 60a and second stackers 60b can be configured respectively. Figure 1 , Figure 2 and Figure 3 In this configuration, one each of the first stacker 60a, the second stacker 60b, the positive electrode second direction transmitter 50p, and the negative electrode second direction transmitter 50p is configured. More than one first stacker 60a and second stacker 60b can be additionally configured along the first direction D1. That is, more than two first stackers 60a and more than two second stackers 60b can be configured. To supply the positive electrode 5p and the negative electrode 5n to the additionally configured first stackers 60a and second stackers 60b, positive electrode second direction transmitters 50p and negative electrode second direction transmitters 50p can also be configured.

[0203] Alternatively, either the first stacker 60a or the second stacker 60b can be configured. In this case, in order to supply the positive electrode 5p and the negative electrode 5n to the additionally configured first stacker 60a or second stacker 60b, a positive electrode second direction transmitter 50p and a negative electrode second direction transmitter 50p can also be configured.

[0204] The first stacker 60a and the second stacker 60b can be configured in more than one pair, and the positive second direction transmitter 50p and the negative second direction transmitter 50p can be configured in more than one pair.

[0205] A pair of positive second-direction transmitters 50p and negative second-direction transmitters 50p can supply positive electrodes 5p and negative electrodes 5n to a pair of first stackers 60a and second stackers 60b. As a similar structure, two or more pairs of first stackers 60a and second stackers 60b, and two or more pairs of positive second-direction transmitters 50p and negative second-direction transmitters 50p can be configured on the positive first-direction transmitters 40p and 40n. The first pair of first stackers 60a and 60b and the second pair of first stackers 60a and 60b can be sequentially configured along the first direction D1 of the positive first-direction transmitters 40p and 40n. The first pair of positive second-direction transmitters 50p and the second pair of positive second-direction transmitters 50p and 50n can also be sequentially configured along the first direction D1 of the positive first-direction transmitters 40p and 40n.

[0206] The first positive electrode supply 50p1 can be driven by the first supply drive unit F1 to reciprocate the first pickup unit P1 and the second pickup unit P2 along the second direction D2 to repeat the predetermined action in the first motion range E1 and the second motion range E2. The first negative electrode supply 50n1 can be driven by the second supply drive unit F2 to reciprocate the third pickup unit P3 and the fourth pickup unit P4 along the second direction D2 to repeat the predetermined action in the first motion range E1 and the second motion range E2.

[0207] In the first motion zone E1, when the first pickup part P1 of the first positive electrode supply 50p1 picks up the positive electrode 5p on the positive electrode first direction transmitter 40p, the second pickup part P2 simultaneously releases the positive electrode 5p to the first stacker 60a.

[0209] In the first motion interval E1, when the fifth pickup part P5 of the second positive electrode supply 50p2 picks up the positive electrode 5p on the positive electrode bridging part 70p, the sixth pickup part P6 simultaneously picks up the positive electrode 5p on the positive electrode suspension stage 80p. When the seventh pickup part P7 of the second negative electrode supply 50n2 picks up the negative electrode 5n on the negative electrode bridging part 70n, the eighth pickup part P8 simultaneously picks up the electrode on the negative electrode suspension stage 80n. In the second motion interval E2, when the fifth pickup part P5 of the second positive electrode supply 50p2 releases the positive electrode 5p to the positive electrode suspension stage 80p, the sixth pickup part P6 simultaneously releases the positive electrode 5p to the second stacker 60b.

The second pickup unit P2 can pick up the positive electrode 5p on the positive electrode first direction transmitter 40p. The first pickup unit P1 can release the positive electrode 5p to the positive electrode alignment stage 61 of the first stacker 60a. Simultaneously, in the first motion zone E1, the second supply drive unit F2 can move the fifth pickup unit P5 to the positive electrode bridging unit 70p and move the sixth pickup unit P6 to the positive electrode suspension stage 80p. The fifth pickup unit P5 can pick up the positive electrode 5p on the positive electrode bridging unit 70p.

[0211] In the second motion zone E2, the first supply drive unit F1 can move the second pickup unit P2 to the positive electrode bridging unit 70p and move the first pickup unit P1 to the positive electrode first direction transmitter 40p. The second pickup unit P2 can release the positive electrode 5p to the positive electrode bridging unit 70p.

The fifth pickup unit P5 can release the positive electrode 5p to the positive electrode suspension stage 80p. The sixth pickup unit P6 can release the positive electrode 5p to the positive electrode alignment stage 61 of the second stacker 60b.

[0212] Reference Figure 2 , Figure 3 and Figure 12 In the first motion zone E1, the second supply drive unit F2 can move the fourth pickup unit P4 to the negative electrode first direction conveyor 40n and the third pickup unit P3 to the negative electrode alignment stage 62 of the second stacker 60b. The fourth pickup unit P4 can pick up the negative electrode 5n on the negative electrode first direction conveyor 40n.

[0215] When the supply operation is repeated in the first movement interval E1 and the second movement interval E2, the positive electrode 5p and the negative electrode 5n can be supplied to the stacker. The stacker can also repeat the sequence of the first movement interval E1 and the second movement interval E2 corresponding to the first stacking interval G1 and the second stacking interval G2 to manufacture the electrode assembly 6.

[0216] Figure 13 This is a diagram illustrating a device layout 100 according to one embodiment.

[0217] According to one embodiment, the equipment layout 100 is a configuration structure of a composite equipment 1 arranged in a secondary battery manufacturing plant, including unwinding machines 20p and 20n, winding changers 10p and 10n, slotters 31p and 31n, dryers 33p and 33n, cutters 32p and 32n, first direction conveyors 40p and 40n, second direction conveyors 50p and 50n, stackers 60a and 60b, etc.

[0218] According to one embodiment, device layout 100 may include: reference to Figures 1 to 9 The description includes multiple composite devices 1, multiple first carriers 110 that convey electrode assemblies 6 manufactured by a first stacker 60a and a second stacker 60b of composite devices 1 along a first direction D1, and a second carrier 120 that receives the electrode assemblies 6 conveyed by the multiple first carriers 110 and conveys them along a second direction D2.

[0219] The composite equipment 1 is a device that configures various devices required for manufacturing electrode assemblies 6 (e.g., roll changers 10p, 10n, uncoilers 20p, 20n, grooving machines 31p, 31n, dryers 33p, 33n, cutters 32p, 32n, first-direction conveyors 40p, 40n, second-direction conveyors 50p, 50n, stackers 60a, 60b) to operate in a single process. The composite equipment 1 is designed so that the various devices occupy a minimal area.

[0220] The first carrier 110 can transport electrode assemblies 6 manufactured by the composite equipment 1. The second carrier 120 can transport electrode assemblies 6 received from the first carrier 110. The first carrier 110 and the second carrier 120 can be implemented by conveyor belts, LMS, and various other transport devices. The first carrier 110 can be configured along a first direction D1. One first carrier 110 can be configured in a first stacker 60a, and one first carrier 110 can be configured in a second stacker 60b. That is, two first carriers 110 can be configured in one composite equipment 1. The first carrier 110 can receive electrode assemblies 6 manufactured by the stacker of the composite equipment 1 and transport them to the second carrier 120. The second carrier 120 can receive electrode assemblies 6 from multiple first carriers 110 and transport them. The second carrier 120 can be configured along a second direction D2.

[0221] Multiple composite devices 1 can be configured such that multiple first carriers 110 are connected toward a second carrier 120. Multiple composite devices 1 can be configured such that stackers 60a and 60b are close to the second carrier 120 while the uncoiler is away from the second carrier 120. Multiple slotting stacking devices can be arranged spaced apart from each other at a predetermined interval W. That is, multiple composite devices 1 can be configured to image comb teeth extending to one side from the second carrier 120. Furthermore, multiple composite devices 1 can be configured to image comb teeth extending to both sides with the second carrier 120 as the center. In this case, electrode assemblies 6 manufactured on both sides can be output to the second carrier 120.

[0222] Multiple composite devices 1 can be arranged spaced apart from each other along the second direction D2. Multiple composite devices 1 can be arranged spaced apart at predetermined intervals W along a second carrier 120 extending along the second direction D2. The interval W between the multiple composite devices 1 can be determined to allow an operator to access and operate between the stackers. An operator can access the space between the multiple composite devices 1. An operator can access and approach the roll changers 10p, 10n, uncoilers 20p, 20n, slotters 31p, 31n, dryers 33p, 33n, cutters 32p, 32n, first-direction conveyors 40p, 40n, second-direction conveyors 50p, 50n, stackers, and first carrier 110 along the first direction D1. This is because multiple devices are arranged in the composite device 1 along the first direction D1. In the manufacturing process of the electrode assembly 6, all materials and operators can move along the first direction D1, while the manufactured electrode assembly 6 moves along the second direction D2, thus simplifying the plant's movement routes.

[0223] According to one embodiment, the device layout 100 may further include a roll transport unit 130 that transports positive electrode roll 2p or negative electrode roll 2n to multiple composite devices 1 and operates automatically. The roll transport unit 130 can move while loaded with positive electrode roll 2p or negative electrode roll 2n and supply roll material to positive electrode roll changer 10p or negative electrode roll changer 10n. Since the roll changers 10p and 10n of the multiple composite devices 1 in the device layout 100 are arranged side-by-side on one side, the movement path of the roll transport unit 130 to the roll changers 10p and 10n can be simplified. Since it takes time for the composite devices 1 to consume the roll material, one roll transport unit 130 can supply roll material to multiple composite devices 1. Furthermore, since the movement path of the roll transport unit 130 to the multiple composite devices 1 is simple, the movement time can be minimized. Therefore, in the device layout 100 according to one embodiment, the number of roll transport units 130 can be relatively small compared to the number of composite devices 1. Therefore, the space occupied by the roll transport unit 130 inside the factory and the space required for the roll transport unit 130 to move can also be minimized.

[0224] The present disclosure has been described in detail above through specific embodiments. The above description is merely an example of applying the principles of the present disclosure, and other configurations may be included without departing from the scope of the present invention.
