[0058] FIG. 8 is a drawing for explaining a first inspection unit (220) of an inspection device (200) for a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention. Specifically, FIG. 8 is a drawing for explaining a first lift (221) of the first inspection unit (220).
[0060] Referring to FIGS. 1, 3 through 7, the first inspection unit (220) is mounted on the first body unit (213) and may include a first lift (221) and a first head (222). The first lift (221) and the first head (222) may be coupled to each other. The first body unit (213) may include a portion extending in the Z direction. The first inspection unit (220) may be positioned on the Z-direction extension portion of the first body unit (213). Specifically, the first lift (221) may extend in the Z direction. The first lift (221) may be positioned on the Z-direction extension portion of the first body unit (213). For example, the first lift (221) may overlap the Z-direction extension portion of the first body unit (213) in the Y direction. Specifically, the first head (222) may be positioned on the first lift (221). For example, the first head (222) is positioned on the first lift (221) and may overlap with the first lift (221) in the Z direction. The first head (222) may be connected to the tray outer joint (210). For example, the first head (222) may be connected to the tray outer joint (210) by the first lift (221) and the first body part (213).
[0061] As described above, the first inspection unit (220) may be configured to inspect the spacing between the first ribs (121). For example, the first inspection unit (220) may be positioned in the Y direction with respect to the first ribs (121). For example, the first ribs (121) may include a first rib (121_1), a second first rib (121_2), a third first rib (121_3), and a fourth first rib (121_4).
[0062] As illustrated in FIG. 4, the first head (222) may include protrusions (222_P1, 222_P2, 222_P3) protruding in the Y direction. Specifically, the first head (222) may include a first protrusion (222_P1), a second protrusion (222_P2), and a third protrusion (222_P3) protruding in the Y direction from the tray outer coupling portion (210). For example, the first protrusion (222_P1), the second protrusion (222_P2), and the third protrusion (222_P3) may protrude from the first body portion (213) in a direction toward the first lips (121). The first protrusion (222_P1), the second protrusion (222_P2), and the third protrusion (222_P3) may be spaced apart from each other in the X direction. The width of each of the first protrusion (222_P1), the second protrusion (222_P2), and the third protrusion (222_P3) may be the first width (W1). The first width (W1) may be less than the normal spacing of the first ribs (121). For example, the first width (W1) may be substantially the same as the minimum normal spacing of the first ribs (121).
[0063] The first head (222) may include a hole (222_H). The hole (222_H) is positioned in the Y direction with respect to the protrusions (222_P1, 222_P2, 222_P3) and may be for coupling the first head (222) to the first lift (221). The hole (222_H) may extend in the Y direction. For example, the hole (222_H) may include a shape that is long in the Y direction.
[0064] As illustrated in FIGS. 5 to 7, the first head (222) can move in the Y direction to inspect the spacing between the first lips (121). Specifically, the first head (222) can move in the Y direction to inspect whether the first lips (121) are arranged at normal spacing. For example, the first head (222) can move in the Y direction on the first lift (221) by means of the hole (222_H) and the latch (221_L). For example, the first head (222) can move in the Y direction while coupled to the first lift (221) by means of the hole (222_H) and the latch (221_L).
[0065] In a first state (S11) as exemplified in FIG. 5, the first head (222) may be spaced apart in the Y direction from the first lips (121_1, 121_2, 121_3, and 121_4). Specifically, the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) may be spaced apart in the Y direction from the first lips (121_1, 121_2, 121_3, and 121_4). For example, the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) may not overlap with the first lips (121_1, 121_2, 121_3, and 121_4) in the X direction.
[0066] In the second state (S12) as exemplified in FIG. 6, the first head (222) can move in the Y direction toward the first ribs (121_1, 121_2, 121_3, and 121_4). Specifically, the first head (222) can move in the Y direction while coupled to the first lift (221). By doing so, the relative position of the first head (222) in the Y direction with respect to the first lift (221) can be changed. For example, the relative position of the first head (222) in the Y direction with respect to the tray outer coupling portion (210) can be changed. In the second state (S12), the first ribs (121_1, 121_2, 121_3, and 121_4) can be arranged at normal intervals.
[0067] In the embodiments, when the first lips (121_1, 121_2, 121_3, and 121_4) are arranged in a first normal spacing (P1), the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) may be inserted between the first lips (121_1, 121_2, 121_3, and 121_4). For example, the first protrusion (222_P1) may be placed between the first first lip (121_1) and the second first lip (121_2). The second protrusion (222_P2) may be placed between the second first lip (121_2) and the third first lip (121_3). A third protrusion (222_P3) may be positioned between the third first lip (121_3) and the fourth first lip (121_4). The protrusions (222_P1, 222_P2, 222_P3) may overlap with the first lips (121_1, 121_2, 121_3, and 121_4) in the X direction. The first normal gap (P1) may be greater than the first width (W1).
[0068] In some other embodiments, unlike illustrated, the first head (222) may not move relative to the first lift (221). For example, the first inspection unit (220) mounted on the first body part (213) may be arranged in the Y direction with the first lips (121_1, 121_2, 121_3, and 121_4), and at the same time, the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) may be configured to be inserted between the first lips (121_1, 121_2, 121_3, and 121_4). For example, the first head (222) may move in the Y direction integrally with the first lift (221).
[0069] In an abnormal state (SX1) as exemplified in FIG. 7, the first head (222) can move in the Y direction toward the first lips (121_1, 121_2, 121_3, and 121_4). Specifically, the first head (222) moves in the Y direction to inspect the gap between the first lips (121_1, 121_2, 121_3, and 121_4), but if any of the gaps between the first lips (121_1, 121_2, 121_3, and 121_4) is an abnormal gap (PX1) smaller than the first width (W1), it may be blocked and unable to move further.
[0070] In the embodiments, if any of the first lips (121_1, 121_2, 121_3, and 121_4) are arranged with an abnormal gap (PX1), the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) may not be inserted between the first lips (121_1, 121_2, 121_3, and 121_4). For example, if the first first lip (121_1) and the second first lip (121_2) are arranged with an abnormal gap (PX1), the first protrusion (222_P1) may collide with the first first lip (121_1) and / or the second first lip (121_2). The first protrusion (222_P1) may not be placed between the first first lip (121_1) and the second first lip (121_2). The second protrusion (222_P2) and the third protrusion (222_P3) may also not be placed between the second first lip (121_2) and the third first lip (121_3), and between the third first lip (121_3) and the fourth first lip (121_4). The protrusions (222_P1, 222_P2, 222_P3) may not overlap with the first lips (121_1, 121_2, 121_3, and 121_4) in the X direction.
[0072] Referring together with FIG. 8, the first inspection unit (220) can move in the Z direction on the first body unit (213). Specifically, the first lift (221) can move in the Z direction on the Z direction extension of the first body unit (213). For example, the relative position of the first head (222) in the Z direction with respect to the first body unit (213) can change. For example, the relative position of the first head (222) in the Z direction with respect to the tray outer coupling unit (210) can change. For example, the height from the inner plate (102) to the first head (222) can change from a first height (H1) to a second height (H2). By doing so, even if the length or position of the first ribs (121) in the Z direction changes, the relative position of the first head (222) in the Z direction can be changed to inspect the gap between the first ribs (121).
[0074] According to exemplary embodiments of the technical concept described with reference to FIGS. 3 to 8, an inspection device (200) for a battery cell activation tray may be provided, comprising a first inspection unit (220) comprising a first head (222) configured to inspect the spacing between the first lips (121). The first head (222) includes protrusions (222_P1, 222_P2, 222_P3) having a first width (W1) less than or equal to the first normal spacing (P1) of the first lips (121), and can inspect whether the first lips (121) are arranged at a normal spacing depending on whether they are inserted between the first lips (121). In particular, the first width (W1) can be designed according to the first normal spacing (P1) of the first ribs (121), so that the first head (222) can be replaced to inspect the battery cell activation tray containing ribs with different normal spacings.
[0075] Additionally, the first head (222) can be moved relative to the Z direction by the first lift (221), so that it can inspect the first ribs (121) regardless of their length or position in the Z direction.
[0077] FIG. 9 is an enlarged view illustrating an inspection device (200) for a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention. Specifically, FIG. 9 is an enlarged view of the EX2 area of FIG. 1.
[0078] FIG. 10 is a drawing for explaining a second inspection unit (230) of an inspection device (200) for a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention. Specifically, FIG. 10 shows a second head (232) of the second inspection unit (230) in a planar view.

FIG. 13 is a drawing for explaining a second inspection unit (230) of an inspection device (200) for a battery cell activation tray according to exemplary embodiments according to the technical concept of the present invention. FIG. 14 is a drawing for explaining a second inspection unit (230) of an inspection device (200) for a battery cell activation tray according to exemplary embodiments according to the technical concept of the present invention. Specifically, FIGS. 11 to 14 illustrate the first state (S21), second state (S22), third state (S23), and abnormal state (SX2) of the second ribs (122) to explain the second inspection unit (230).
[0081] Referring to FIGS. 1, 9 through 14, the second inspection unit (230) is mounted on the second body unit (215) and may include a second lift (231) and a second head (232). The second lift (231) and the second head (232) may be coupled to each other. The second body unit (215) may include a portion extending in the Z direction. The second inspection unit (230) may be positioned on the Z-direction extension portion of the second body unit (215). Specifically, the second lift (231) may extend in the Z direction. The second lift (231) may be positioned on the Z-direction extension portion of the second body unit (215). For example, the second lift (231) may overlap the Z-direction extension portion of the second body unit (215) in the Y direction. Specifically, the second head (232) may be positioned on the second lift (231). For example, the second head (232) is positioned on the second lift (231) and may overlap with the second lift (231) in the Z direction. The second head (232) may be connected to the tray outer joint (210). For example, the second head (232) may be connected to the tray outer joint (210) by the second lift (231) and the second body part (215).
[0082] As described above, the second inspection unit (230) can move in the X direction along the bar (240). Specifically, the second inspection unit (230) is coupled to the second body unit (215), and the second body unit (215) can slide in the X direction on the bar (240). Specifically, a U-shaped unit (216) may be provided on the second body unit (215). The U-shaped unit (216) protrudes in the Y direction from the second body unit (215) and may include a U-shape. For example, the U-shaped unit (216) may protrude in a direction opposite to the plurality of ribs (120) and may include a hole (216_H) that is long in the Y direction. The hole (216_H) may be penetrated by the bar (240). The U-shaped unit (216) can slide in the X direction along the bar (240) while being penetrated by the bar (240).
[0083] As described above, the second inspection unit (230) may be configured to inspect the spacing between the second ribs (122). For example, the second inspection unit (230) may be positioned in the Y direction with respect to the second ribs (122). For example, the second ribs (122) may include a first second rib (122_1), a second second rib (122_2), a third second rib (122_3), a fourth second rib (122_4), and a fifth second rib (122_5).
[0084] As illustrated in FIG. 10, the second head (232) may include protrusions (232_P1, 232_P2) protruding in the Y direction. Specifically, the second head (232) may include a first protrusion (232_P1) and a second protrusion (232_P2) protruding in the Y direction from the tray outer coupling portion (210). For example, the first protrusion (232_P1) and the second protrusion (232_P2) may protrude from the second body portion (215) in a direction toward the second ribs (122). The first protrusion (232_P1) and the second protrusion (232_P2) may be spaced apart from each other in the X direction. The width of each of the first protrusion (232_P1) and the second protrusion (232_P2) may be a second width (W2). The second width (W2) may be less than the normal spacing of the second ribs (122). For example, the second width (W2) may be substantially the same as the minimum normal spacing of the second ribs (122).
[0085] The second head (232) may include a hole (232_H). The hole (232_H) is positioned in the Y direction with respect to the protrusions (232_P1, 232_P2) and may be for connecting the second head (232) to the second lift (231).
[0086] As illustrated in FIGS. 11 to 14, the second head (232) can move in the Y direction to inspect the spacing between the second lips (122). Specifically, the second head (232) can move in the Y direction to inspect whether the second lips (122) are arranged at normal spacing. For example, the second head (232) can move in the Y direction while coupled to the second lift (231) and the second body part (215). For example, the second inspection part (230) can move in the Y direction as a whole.
[0087] In the first state (S21) as exemplified in FIG. 11, the second head (232) can move in the Y direction toward the second ribs (122_1, 122_2, and 122_3). Specifically, the second head (232) can move in the Y direction integrally with the second lift (231). For example, the second head (232) can move in the Y direction integrally with the second lift (231), the second body part (215), and the U-shaped part (216). For example, the relative position of the second inspection part (230) in the Y direction with respect to the tray outer coupling part (210) can change. At this time, the U-shaped part (216) can move in the Y direction toward the second ribs (122_1, 122_2, and 122_3) while penetrating the bar (240). In the first state (S21), the second ribs (122_1, 122_2 and 122_3) can be arranged at normal intervals.
[0088] In embodiments, when the second lips (122_1, 122_2 and 122_3) are arranged in a second normal spacing (P2), the protrusions (232_P1, 232_P2) of the second head (232) may be inserted between the second lips (122_1, 122_2 and 122_3). For example, the first protrusion (232_P1) may be placed between the first second lip (122_1) and the second second lip (122_2). The second protrusion (232_P2) may be placed between the second second lip (122_2) and the third second lip (122_3). The protrusions (232_P1, 232_P2) may overlap with the second ribs (122_1, 122_2 and 122_3) in the X direction. The second normal gap (P2) may be greater than the second width (W2).
[0089] In the second state (S22) as exemplified in FIG. 12, the second head (232) can move in the X direction along the bar (240). Specifically, the second head (232) can move in the X direction integrally with the second lift (231). For example, the second head (232) can move in the X direction integrally with the second lift (231), the second body part (215), and the U-shaped part (216). At this time, the U-shaped part (216) can slide in the X direction while penetrating the bar (240). By doing so, the relative position of the second inspection part (230) in the X direction with respect to the tray outer coupling part (210) can be changed. For example, the relative position of the second head (232) in the X direction with respect to the tray outer coupling part (210) can be changed. For example, the second head (232) can move in the X direction to check the gap between the second lips (122_1, 122_2, and 122_3) and then check the gap between the second lips (122_3, 122_4, and 122_5).
[0090] In the third state (S23) as exemplified in FIG. 13, the second head (232) can move in the Y direction toward the second ribs (122_3, 122_4, and 122_5). Specifically, the second head (232) can move in the Y direction integrally with the second lift (231). For example, the second head (232) can move in the Y direction integrally with the second lift (231), the second body part (215), and the U-shaped part (216). For example, the relative position of the second inspection part (230) in the Y direction with respect to the tray outer coupling part (210) can change. At this time, the U-shaped part (216) can move in the Y direction toward the second ribs (122_3, 122_4, and 122_5) while penetrating the bar (240). In the third state (S23), the second ribs (122_3, 122_4, and 122_5) can be arranged at normal intervals.
[0091] In the embodiments, when the second lips (122_3, 122_4, and 122_5) are arranged in a second normal spacing (P2), the protrusions (232_P1, 232_P2) of the second head (232) can be inserted between the second lips (122_3, 122_4, and 122_5). For example, the first protrusion (232_P1) can be placed between the third second lip (122_3) and the fourth second lip (122_4). The second protrusion (232_P2) can be placed between the fourth second lip (122_4) and the fifth second lip (122_5). The protrusions (232_P1, 232_P2) may overlap with the second ribs (122_3, 122_4, and 122_5) in the X direction. The second normal gap (P2) may be greater than the second width (W2).
[0092] In an abnormal state (SX2) as exemplified in FIG. 14, the second head (232) can move in the Y direction toward the second lips (122_1, 122_2, and 122_3). Specifically, the second head (232) moves in the Y direction to inspect the gap between the second lips (122_1, 122_2, and 122_3), but if any of the gaps between the second lips (122_1, 122_2, and 122_3) is an abnormal gap (PX2) smaller than the second width (W2), it may be blocked and unable to move further.
[0093] In the embodiments, if any of the second lips (122_1, 122_2, and 122_3) are arranged with an abnormal gap (PX2), the protrusions (232_P1, 232_P2) of the second head (232) may not be inserted between the second lips (122_1, 122_2, and 122_3). For example, if the first second lip (122_1) and the second second lip (122_2) are arranged with an abnormal gap (PX2), the first protrusion (232_P1) may collide with the first second lip (122_1) and / or the second second lip (122_2). The first protrusion (232_P1) may not be placed between the first second lip (122_1) and the second second lip (122_2). The second protrusion (232_P2) may not be placed between the second second lip (122_2) and the third second lip (122_3). The protrusions (232_P1, 232_P2) may not overlap with the second lips (122_1, 122_2, and 122_3) in the X direction.
[0094] In the embodiments, similar to what was described with reference to FIG. 8, the second inspection unit (230) can move in the Z direction on the second body unit (215). Specifically, the second lift (231) can move in the Z direction on the Z direction extension of the second body unit (215). For example, the relative position of the second head (232) in the Z direction with respect to the second body unit (215) can be changed. For example, the relative position of the second head (232) in the Z direction with respect to the tray outer coupling unit (210) can be changed. By doing so, even if the length or position of the second ribs (122) in the Z direction changes, the relative position of the second head (232) in the Z direction can be changed to inspect the gap between the second ribs (122).
[0096] According to exemplary embodiments of the technical concept described with reference to FIGS. 9 to 14, an inspection device (200) for a battery cell activation tray may be provided, comprising a second inspection unit (230) including a second head (232) configured to inspect the spacing between the second lips (122). The second head (232) includes protrusions (232_P1, 232_P2) having a second width (W2) less than or equal to the second normal spacing (P2) of the second lips (122), and can inspect whether the second lips (122) are arranged at a normal spacing depending on whether they are inserted between the second lips (122). In particular, the second width (W2) can be designed according to the second normal spacing (P2) of the second lips (122), so it is possible to inspect a battery cell activation tray including lips with different normal spacing by replacing the second head (232).
[0097] Additionally, the second head (232) can be moved relative to the Z direction by the second lift (231), so that it can inspect the second ribs (122) regardless of their length or position in the Z direction.
[0099] FIG. 15 is a drawing for explaining an inspection device (200) for a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention. Specifically, FIG. 15 is a drawing for explaining a sliding measuring part (217) of an inspection device (200) for a battery cell activation tray.
[0100] Referring to FIG. 15, the sliding measuring part (217) may be provided on the outer connecting part (210) of the tray. For example, the sliding measuring part (217) may be placed on the side wall of the first body part (213). The sliding measuring part (217) may extend in the Y direction.
[0101] In the embodiments, the sliding measuring unit (217) can measure the distance (DY) in the Y direction from the side wall of the outer plate (101) to the side wall of the inner plate (102). Specifically, the sliding measuring unit (217) can inspect whether the inner plate (102) and the plurality of ribs (120) on the inner plate (102) are incorrectly assembled. For example, the distance (DY) in the Y direction from the side wall of the outer plate (101) to the side wall of the inner plate (102) can be compared with a reference distance to inspect whether the inner plate (102) and the plurality of ribs (120) on the inner plate (102) are incorrectly assembled.
[0103] According to exemplary embodiments based on the technical concept of the present invention, an inspection device (200) for a battery cell activation tray with improved performance and reliability may be provided.
[0104] According to exemplary embodiments based on the technical concept of the present invention, an inspection device (200) for a battery cell activation tray with improved compatibility may be provided.
[0106] (2nd Example)
[0107] FIG. 16 is a flowchart of a method for inspecting a battery cell activation tray (S100) according to exemplary embodiments of the technical concept of the present invention.
[0108] FIG. 17 is a flowchart for explaining a method (S100) for inspecting a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention.
[0109] FIG. 18 is a flowchart for explaining a method (S100) for inspecting a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention.
[0110] FIG. 19 is a flowchart for explaining a method (S100) for inspecting a battery cell activation tray according to exemplary embodiments of the technical concept of the present invention.
[0112] Referring to FIG. 16, the inspection method (S100) of a battery cell activation tray may include a first inspection step (S110) using a first inspection unit to inspect whether the first lips are arranged at normal intervals, and a second inspection step (S120) using a second inspection unit to inspect whether the second lips are arranged at normal intervals.
[0113] Specifically, referring to FIGS. 1, FIGS. 3, and FIGS. 9 together, in the first inspection step (S110), the first inspection unit (220) can be used to inspect whether the first ribs (121) are arranged at normal intervals, and likewise, in the second inspection step (S120), the second inspection unit (230) can be used to inspect whether the second ribs (122) are arranged at normal intervals. For the description of the first inspection unit (220), the first ribs (121), the second inspection unit (230), and the second ribs (122), the above description may be referenced.
[0114] Referring to FIG. 17, the first inspection step (S110) may include a step (S111) in which a first head moves toward the first lips in the Y direction and a step (S112) in which the first lips are arranged at normal intervals.
[0115] Specifically, referring to FIGS. 1, 3 through 7 together, the first head (222) can move in the Y direction toward the first ribs (121). For example, the first inspection unit (220) can change from a first state (S11) to a second state (S12) or an abnormal state (SX1). The first inspection unit (220) can determine whether the first ribs (121) are arranged at a first normal interval (P1).
[0116] For example, as in the second state (S12) described with reference to FIG. 6, the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) can be inserted between the first lips (121_1, 121_2, 121_3, and 121_4). At this time, it can be determined that the first lips (121) are arranged in a first normal spacing (P1).
[0117] For example, as in the abnormal state (SX1) described with reference to FIG. 7, the protrusions (222_P1, 222_P2, 222_P3) of the first head (222) may not be inserted between the first lips (121_1, 121_2, 121_3, and 121_4). In this case, it may be determined that the first lips (121) are not arranged in the first normal spacing (P1).
[0119] Referring to FIGS. 18 and 19, the second inspection step (S120) may include a step (S121) of inspecting whether the first central rib and the second central rib are arranged at normal intervals, a step (S122) of sliding the second inspection unit along the bar in the X direction, and a step (S123) of inspecting whether the second central rib and the third central rib are arranged at normal intervals.
[0120] In the embodiments, the step (S121) of checking whether the first central lip and the second central lip are arranged at normal intervals may include the step (S121_1) of moving the second head toward the second lip in the Y direction and the step (S121_2) of determining whether the second lip is arranged at normal intervals.
[0121] Specifically, referring to FIGS. 1, 9 through 14 together, the second head (232) can move in the Y direction toward the second ribs (122). For example, the second inspection unit (230) can be placed in a first state (S21) or an abnormal state (SX2). The second inspection unit (230) can determine whether the second ribs (122) are arranged at a second normal interval (P2). For example, the second ribs (122_1, 122_2, and 122_3) may include a first central rib and a second central rib.
[0122] For example, as in the second state (S22) described with reference to FIG. 11, the protrusions (232_P1, 232_P2) of the second head (232) can be inserted between the second lips (122_1, 122_2, and 122_3). At this time, it can be determined that the second lips (122) are arranged in a second normal spacing (P2).
[0123] For example, as in the abnormal state (SX2) described with reference to FIG. 14, the protrusions (232_P1, 232_P2) of the second head (232) may not be inserted between the second lips (122_1, 122_2, and 122_3). In this case, it may be determined that the second lips (122) are not arranged in the second normal spacing (P2).
[0124] In the embodiments, after the step (S121) of checking whether the first central lip and the second central lip are arranged at normal intervals, the step (S122) of sliding the second inspection unit along the bar in the X direction is performed, and subsequently, the step (S123) of checking whether the second central lip and the third central lip are arranged at normal intervals may be performed.
[0125] Specifically, referring to FIGS. 1 and FIGS. 9 to 14 together, the state can change from the first state (S21) through the second state (S22) to the third state (S23).
[0126] For example, as in the second state (S22) as illustrated in FIG. 12, the second head (232) can move in the X direction along the bar (240). For example, the second head (232) can move in the X direction integrally with the second lift (231), the second body part (215), and the U-shaped part (216). At this time, the U-shaped part (216) can slide in the X direction while penetrating the bar (240).
[0127] In the embodiments, the step (S123) of checking whether the second central lip and the third central lip are arranged at normal intervals can be performed as described with reference to FIGS. 1, FIGS. 9 to 14, and FIG. 19. For example, the second head can move in the Y direction toward the second lip and determine whether the second lip is arranged at normal intervals. For example, the second lip (122_3, 122_4, and 122_5) may include the second central lip and the third central lip.
[0128] For example, as in the third state (S23) as exemplified in FIG. 13, the second head (232) can move in the Y direction toward the second lips (122_3, 122_4, and 122_5). At this time, when the protrusions (232_P1, 232_P2) of the second head (232) are inserted between the second lips (122_3, 122_4, and 122_5), it can be determined that the second lips (122) are arranged in a second normal spacing (P2). Alternatively, if the protrusions (232_P1, 232_P2) of the second head (232) are not inserted between the second lips (122_3, 122_4, and 122_5), it can be determined that the second lips (122) are not arranged in the second normal spacing (P2).
[0130] According to exemplary embodiments of the technical concept described with reference to FIGS. 16 to 19, a method (S100) for inspecting a battery cell activation tray for inspecting whether the first ribs and the second ribs are arranged at normal intervals may be provided. Specifically, a method (S100) for inspecting a battery cell activation tray performed using an inspection device (200) for a battery cell activation tray may be provided.
[0131] According to exemplary embodiments based on the technical concept of the present invention, a method (S100) for inspecting a battery cell activation tray with improved performance and reliability may be provided.
[0133] The present invention has been described in more detail above through drawings and embodiments.
