[0003] Specifically, when the electrode plate supply device supplies the electrode plates composed of the positive electrode plates or the negative electrode plates to the stacking stage, the electrode plates and the separators are stacked by the electrode plate stacking device on the stacking stage to form an electrode assembly.

[0054] Hereinafter, the preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and the following description. However, the present disclosure is not limited to the embodiments described herein and may also be embodied in other forms. Throughout the specification, the same reference numerals represent the same components.

[0055] Hereinafter, an electrode plate supply device according to an embodiment of the present disclosure will be described.

[0056] Figure 1 FIG. 1 is a diagram illustrating an electrode plate supply device according to an embodiment of the present disclosure.

[0057] Reference Figure 1 In detail, the electrode plate supply device 100 includes an electrode plate supply unit 120 , an electrode plate moving unit 130 , an electrode plate transferring unit 140 , an electrode plate conveying unit 150 , and an electrode plate stacking unit 160 .

[0058] First, the electrode plate supply unit 120 will be described.

[0059] The electrode plate supply part 120 may supply the electrode plate 122 formed of a positive electrode plate or a negative electrode plate.

[0060] For example, Figure 1 As shown, the electrode plate supply unit 120 may include at least one electrode box 121 , and the electrode box 121 is loaded with at least one electrode plate 122 .

[0061] Figure 2This is a diagram showing an electrode cartridge in which an electrode plate supported by a support plate is positioned lower than a holding position.

[0062] Reference Figure 2 In detail, the electrode box 121 may include a support plate 123 and an electrode plate sensing sensor 124 .

[0063] The support plate 123 is configured to support at least one electrode plate 122 loaded on the electrode cartridge 121 and to be able to rise or fall.

[0064] The electrode plate sensing sensor 124 is configured to sense the position of the electrode plate 122 , and may be configured by an existing sensor capable of sensing the position of an object.

[0065] The electrode plate sensing sensor 124 can sense whether the electrode plate 122 is located at a preset holding position held by the electrode plate moving part 130 .

[0066] For example, Figure 2 As shown, multiple electrode plate sensing sensors 124 can be arranged on the electrode box 121, and the virtual line segment L connecting one electrode plate sensing sensor 124 and another electrode plate sensing sensor 124 is arranged on the electrode box parallel to the surface of the electrode plate 122 loaded on the electrode box 121.

[0067] Figure 3 This is a diagram showing an electrode cartridge in which an electrode plate supported by a support plate is positioned at a gripping position.

[0068] In addition, if Figure 3 As shown, when it is sensed that the support plate 123 rises so that the uppermost electrode plate 122 loaded in the electrode box 121 is located in contact with the virtual line segment L, the electrode plate sensing sensor 124 can sense that the uppermost electrode plate 122 loaded in the electrode box 121 is located at a preset holding position.

[0069] As described above, when the electrode plate sensing sensor 124 senses that the uppermost electrode plate 122 loaded on the electrode box 121 is located at the preset holding position, the electrode plate moving unit 130 can hold the uppermost electrode plate 122 loaded on the electrode box 121 .

[0070] Figure 4 This is a diagram showing an electrode plate supply unit configured to form electrode plates from an electrode roll and load the electrode plates into an electrode cartridge.

[0071] Take another example to illustrate, Figure 4 As shown, the electrode plate supply unit 120 may include an electrode roll 125 , a cutting mechanism 126 , a detection sensor 127 , an electrode plate discharging mechanism 128 - 1 , an electrode plate receiving device 129 , an electrode plate loading mechanism 128 - 2 , and an electrode box 121 .

[0072] like Figure 4 As shown, the electrode roll 125 is an electrode wound in a roll shape.

[0073] When one end of the electrode roll 125 is unwound and moved by a conveyor belt or the like, the cutting mechanism 126 may cut a portion of the electrode roll 125 to form at least one electrode plate 122 .

[0074] The detection sensor 127 can detect whether the shape of the electrode plate 122 formed by the cutting mechanism 126 is damaged. For example, the detection sensor 127 can be composed of a visual sensor to detect whether the electrode plate 122 is formed in a pre-set shape without being damaged.

[0075] The electrode plate discharge mechanism 128-1 may be composed of a mechanism capable of holding and transporting the electrode plate 122, and if the electrode plate 122 is not formed into a predetermined shape, the electrode plate 122 may be discharged to the outside of the electrode plate supply unit 120. In other words, the electrode plate discharge mechanism 128-1 may discharge an electrode plate 122 with a damaged shape to the outside.

[0076] The electrode plate accommodation device 129 can accommodate the electrode plate 122 with a damaged shape discharged by the electrode plate discharge mechanism 128 - 1 , and the electrode plate 122 accommodated in the electrode plate accommodation device 129 can be discarded.

[0077] The electrode plate loading mechanism 128 - 2 may be composed of a mechanism capable of holding and transporting the electrode plate 122 , and may load the electrode plate 122 that has not been discharged to the outside by the electrode plate discharging mechanism 128 - 1 onto the electrode box 121 .

[0078] Figure 5 This is a diagram showing an electrode plate supply unit configured to form electrode plates from an electrode roll and transfer the electrode plates.

[0079] Let’s take another example. Figure 5 As shown, the electrode plate supply unit 120 may include an electrode roll 125 , a cutting mechanism 126 , a detection sensor 127 , an electrode plate discharging mechanism 128 - 1 , and an electrode plate receiving device 129 .

[0080] Figure 5 The electrode roll 125, cutting mechanism 126, detection sensor 127, electrode plate discharge mechanism 128-1 and electrode plate receiving device 129 are shown in FIG. Figure 4 The electrode roll 125, cutting mechanism 126, detection sensor 127, electrode plate discharge mechanism 128-1 and electrode plate storage device 129 shown have the same structure.

[0081] but, Figure 5 The electrode plate supply unit 120 shown is connected to Figure 4 The difference of the electrode plate supply unit 120 shown is that the electrode plates 122 that are not discharged to the outside by the electrode plate discharge mechanism 128-1 are not loaded onto the electrode box 121, but are transferred to the electrode plate stacking unit 160 described later. In this case, the electrode plates 122 can be transferred to the electrode plate stacking unit 160 by an existing transfer device including a conveyor belt.

[0082] That is, including Figure 5 The electrode plate supply device 100 of the electrode plate supply unit 120 shown may not include the electrode plate moving unit 130 and the electrode plate transferring unit 140 described later, but may include the electrode plate conveying unit 150 and the electrode plate stacking unit 160 .

[0083] Next, the electrode plate moving unit 130 will be described.

[0084] The electrode plate moving unit 130 may carry the electrode plate 122 supplied from the electrode plate supply unit 120 to the electrode plate transfer unit 140 described later, and may be composed of a mechanism capable of gripping and carrying the electrode plate 122 .

[0085] For example, the electrode plate moving part 130 may be composed of existing machines including a pick and place (P&P) machine and a selective compliance assembly robot arm (SCARA) robot, but the structure of the electrode plate moving part 130 is not limited thereto.

[0086] The electrode plate moving part 130 can hold and rotate the electrode plate 122 so that the electrode plate 122 rotates while keeping one surface thereof parallel to a direction perpendicular to the direction of gravity.

[0087] In addition, the electrode plate moving unit 130 can move the electrode plate 122 in a first direction and a second direction perpendicular to the first direction and transport it to the electrode plate transfer unit 140. In this case, the first direction can be a direction parallel to the direction of gravity, and the second direction can be a direction perpendicular to the direction of gravity.

[0088] In addition, when the electrode plate supply unit 120 includes a plurality of electrode cassettes 121 , the electrode plate moving unit 130 may sequentially or simultaneously grasp the electrode plate 122 from each of the plurality of electrode cassettes 121 and convey the electrode plate 122 to the electrode plate transfer unit 140 .

[0089] At this time, the electrode plate moving unit 130 may hold the electrode plates 122 one by one from each of the plurality of electrode boxes 121 .

[0090] On the other hand, the preset holding position of the electrode plate 122 can be a set position so that the electrode plate 122 is not damaged by the force between the electrode plate moving part 130 and the electrode plate 122 when the electrode plate moving part 130 contacts the electrode plate 122 in order to hold the electrode plate 122.

[0091] That is, if the electrode plate moving part 130 holds the electrode plate 122 when the electrode plate 122 is not located at a preset holding position, the force between the electrode plate moving part 130 and the electrode plate 122 may damage the shape of the electrode plate 122 .

[0092] However, as described above, since the electrode plate moving part 130 of the present disclosure is configured to hold the electrode plate 122 only when the electrode plate 122 is located at a preset holding position, the force between the electrode plate moving part 130 and the electrode plate 122 can be prevented from damaging the shape of the electrode plate 122.

[0093] Therefore, it is possible to prevent the battery cell from including the electrode plate 122 having a damaged shape.

[0094] Next, the electrode plate transfer unit 140 will be described.

[0095] like Figure 1 As shown, the electrode plate transfer unit 140 may transfer the electrode plate 120 carried by the electrode plate moving unit 130 .

[0096] The electrode plate transfer unit 140 may be formed of an existing article transport mechanism including a conveyor belt and a moving plate capable of reciprocating the object, but the structure of the electrode plate transfer unit 140 is not limited thereto.

[0097] At this time, the electrode plate 122 can be placed on the electrode plate transfer unit 140 and transferred so that the two longest sides of the four sides of the electrode plate 122 are parallel or perpendicular to the direction in which the electrode plate transfer unit 140 transfers the electrode plate 122.

[0098] On the other hand, since the electrode plate moving part 130 can hold and rotate the moving electrode plate 122, the electrode box 121 can be arranged adjacent to the electrode plate transferring part 140, so that the two longest sides of the four sides of the electrode plate 122 loaded on the electrode box 121 are in a state parallel or perpendicular to the direction in which the electrode plate transferring part 140 transfers the electrode plate 122.

[0099] Next, the electrode plate conveying unit 150 will be described.

[0100] The electrode plate conveying unit 150 may convey the electrode plate 122 transferred from the electrode plate transferring unit 140 to an electrode plate stacking unit 160 to be described later.

[0101] The electrode plate conveying unit 150 may be composed of existing machines including a pick and place (P&P) machine and a selective compliance assembly robot arm (SCARA) robot, but the structure of the electrode plate conveying unit 150 is not limited thereto.

[0102] The electrode plate conveying unit 150 can grip and rotate the electrode plate 122 so that the electrode plate 122 rotates while keeping one surface thereof parallel to a direction perpendicular to the direction of gravity.

[0103] In addition, the electrode plate transport unit 150 can move the electrode plate 122 in a first direction and a second direction perpendicular to the first direction and transport it to the electrode plate stacking unit 160. In this case, the first direction may be a direction parallel to the direction of gravity, and the second direction may be a direction perpendicular to the direction of gravity.

[0104] Figure 6 This is a diagram showing a state in which an electrode plate is conveyed by an electrode plate conveying unit that conveys the electrode plate in the first direction and the second direction without rotation.

[0105] For example, Figure 6 As shown, the electrode plate conveying unit 150 can move the electrode plate 122 along a first direction and a second direction perpendicular to the first direction and convey the electrode plate 122 to the electrode plate stacking unit 160 .

[0106] Figure 7 This is a diagram showing a state in which an electrode plate is conveyed by an electrode plate conveying unit that conveys the electrode plate in a first direction and a second direction while rotating.

[0107] As another example, Figure 7 As shown, the electrode plate conveying unit 150 can also rotate the electrode plate 122 while moving the electrode plate 122 in a first direction and a second direction perpendicular to the first direction while conveying the electrode plate 122 to the electrode plate stacking unit 160. That is, the electrode plate 122 can be rotated in a manner such that the directions of two long sides of the four sides of the electrode plate 122 are changed, and then conveyed to the electrode plate stacking unit 160.

[0108] Next, the electrode plate stacking unit 160 will be described.

[0109] The electrode plates 122 conveyed by the electrode plate conveying unit 150 are stacked on the electrode plate stacking unit 160 .

[0110] For example, the positive electrode plates and the negative electrode plates conveyed by the electrode plate conveying unit 150 may be alternately stacked on the electrode plate stacking unit 160 with separators interposed therebetween.

[0111] Such an electrode plate stacking part 160 may be constituted by a table on which a predetermined object can be placed, but the configuration of the electrode plate stacking part 160 is not limited thereto.

[0112] Hereinafter, a method for supplying an electrode plate according to an embodiment of the present disclosure will be described.

[0113] Figure 8 is a flowchart illustrating an electrode plate supplying method according to one embodiment of the present disclosure.

[0114] Reference Figure 8 The electrode plate supply method includes: a first step S10 of supplying the electrode plate 122; a second step S20 of transporting the electrode plate 122 to the electrode plate transfer unit 140; a third step S30 of transferring the electrode plate 122; and a fourth step S40 of transporting the electrode plate 122 to the electrode plate stacking unit 160.

[0115] First, the first step S10 will be described.

[0116] The first step S10 is a step of supplying an electrode plate 122 through the electrode plate supply part 120 , which includes an electrode box 121 loaded with at least one electrode plate 122 formed of a positive electrode plate or a negative electrode plate.

[0117] The configurations of the electrode cassette 121 and the electrode plate supply unit 120 are the same as those of the electrode cassette 121 and the electrode plate supply unit 120 of the aforementioned electrode plate supply device 100 .

[0118] That is, the electrode cartridge 121 may include a support plate 123 configured to support the electrode cartridge 121 and to be able to rise or fall.

[0119] In addition, the electrode box 121 may include an electrode plate sensing sensor 124 , which can sense whether the electrode plate 122 is located at a preset holding position held by the electrode plate moving part 130 .

[0120] On the other hand, the support plate 123 can rise or fall so that the electrode plate 122 loaded at the top among the electrode plates 122 loaded on the electrode box 121 is located at a preset holding position, and when the electrode plate 122 is located at the preset holding position, the electrode plate moving part 130 can hold the electrode plate 122 loaded on the electrode box 121.

[0121] Next, the second step S20 will be described.

[0122] The second step S20 is a step of conveying the electrode plate 122 from the electrode box 121 to the electrode plate transfer unit 140 by the electrode plate moving unit 130 .

[0123] The configuration of the electrode plate moving part 130 is the same as the configuration of the electrode plate moving part 130 of the aforementioned electrode plate supply device 100 .

[0124] Next, the third step S30 will be described.

[0125] The third step S30 is a step of transferring the electrode plate 122 by the electrode plate transfer unit 140 .

[0126] The configuration of the electrode plate transfer unit 140 is the same as that of the electrode plate transfer unit 140 of the aforementioned electrode plate supply device 100 .

[0137] The structure of the detection sensor 127 and the electrode plate discharge mechanism 128-1 is similar to that of the electrode plate supply device 100 described above. Figure 4 The configurations of the detection sensor 127 and the electrode plate discharge mechanism 128 - 1 of the electrode plate supply unit 120 shown are the same.

[0138] Next, the second step S200 will be described.

[0139] The second step S200 is a step of conveying the electrode plate 122 from the electrode box 121 to the electrode plate transfer unit 140 by the electrode plate moving unit 130 .

[0140] The configuration of the electrode plate moving part 130 is the same as the configuration of the electrode plate moving part 130 of the aforementioned electrode plate supply device 100 .

[0147] Hereinafter, an electrode plate supplying method according to yet another embodiment of the present disclosure will be described.

[0148] Figure 10 is a flowchart illustrating an electrode plate supplying method according to yet another embodiment of the present disclosure.

[0149] Reference Figure 10 The electrode plate supply method includes: a first step S1000 , in which the electrode plate supply unit 120 including the electrode roll 125 transfers the electrode plate 122 ; and a second step S2000 , in which the electrode plate 122 is transported to the electrode plate stacking unit 160 .

[0150] First, the first step S1000 will be described.

[0151] The first step S1000 is a step of transferring the electrode plate 122 through the electrode plate supply part 120 including the electrode roll 125 and the cutting mechanism 126 that cuts a portion of the electrode roll 125 supplied from the electrode roll 125 to form at least one electrode plate 122 .

[0152] The structure of the electrode roll 125 and the cutting mechanism 126 is similar to that of the electrode plate supply device 100 described above. Figure 5 The electrode roll 125 and the cutting mechanism 126 of the electrode plate supply unit 120 shown have the same configuration.

[0153] In addition, the electrode plate supply unit 120 includes a detection sensor 127 capable of detecting whether the electrode plate 122 is formed in a preset shape, and includes an electrode plate discharge mechanism 128-1. When the electrode plate 122 is not formed in a preset shape, the electrode plate discharge mechanism 128-1 discharges the electrode plate 122 to the outside of the electrode plate supply unit 120.

[0154] The structure of the detection sensor 127 and the electrode plate discharge mechanism 128-1 is similar to that of the electrode plate supply device 100 described above. Figure 5 The configurations of the detection sensor 127 and the electrode plate discharge mechanism 128 - 1 of the electrode plate supply unit 120 shown are the same.

[0155] Unlike the first step S100 of the electrode plate supply method described above, in the first step S1000 of the electrode plate supply method, the electrode plates 122 that are not discharged to the outside by the electrode plate discharge mechanism 128-1 are not loaded onto the electrode box 121, but are transferred to the electrode plate stacking unit 160 described later. In this case, the electrode plates 122 can be transferred to the electrode plate stacking unit 160 by an existing transfer device including a conveyor belt.

[0156] Next, the second step S2000 will be described.

[0157] The second step S2000 is a step of conveying the electrode plate 122 transferred from the electrode plate transfer unit 120 to the electrode plate stacking unit 160 by the electrode plate conveying unit 150 .

[0158] The configurations of the electrode plate conveying unit 150 and the electrode plate stacking unit 160 are the same as those of the electrode plate conveying unit 150 and the electrode plate stacking unit 160 of the aforementioned electrode plate supply device 100 .

[0159] As described above, according to the electrode plate supply device and electrode plate supply method disclosed herein, electrode plates with damaged shape are detected by detection sensors and discharged to the outside, or the shape of electrode plates held by a mechanism for transporting the electrode plates is prevented from being damaged, thereby providing an effect that can prevent defects in battery cells manufactured from the electrode plates.
