[0103] Figures 7 to 11 are drawings illustrating a secondary battery manufacturing system according to some embodiments of the present disclosure. For convenience of explanation, the moving belt and guide rail are not shown. The socket (100) described below may be the socket (100) described in Figures 4 to 6.

[0104] Referring to FIGS. 1 and 7, a pair of socket cases (200) may be placed on a moving device (e.g., 30 of FIG. 1). As illustrated, each socket case (200) may be placed facing each other. The socket case (200) may include a bearing (210) placed on the outside. The bearing (210) may be placed on a guide rail (e.g., 34 of FIG. 1).

[0105] The sockets (100) can be coupled to each socket case (200). For example, the protruding lines of the sockets (100) can be coupled to the grooves of the socket cases (200). As illustrated, the sockets (100) can be positioned facing each other. The sockets (100) can be positioned so that the first mounting portion (SP1) is exposed.

[0106] The coupling member (220) can be coupled to the socket (100) and the socket case (200) to fix the socket (100) and the socket case (200). For example, the coupling member (220) can be inserted into a groove formed on one surface of the socket (100) and a groove formed on one surface of the socket case (200). The coupling member (220) can prevent the socket (100) from being separated from the socket case (200). For example, the coupling member (220) can be an index plunger.

[0107] FIG. 8 is a diagram illustrating the operation of a fixing device and a separation device according to some embodiments of the present disclosure. For convenience of explanation, the following description focuses on the socket (100) positioned on the right side among the pair of sockets (100) of FIG. 7.

[0108] Referring to FIG. 8, the fixing device (300) can grip the socket case (200). Specifically, the fixing device (300) can move toward the bearing (210) of the socket case (200). Subsequently, the fixing device (300) can grip the bearing (210) of the socket case (200). The fixing device (300) can prevent the socket case (200) from moving when the socket (100) is separated or coupled to the socket case (200).

[0109] Next, the separation device (400) can separate the joining member (220). Specifically, the separation device (400) can grip the joining member (220). Thereafter, the separation device (400) can move the joining member (220) in the negative second direction (-Y) to separate it from the groove of the socket (100) and the groove of the socket case (200).

[0110] FIG. 9 is a drawing illustrating an operation of a rotating device gripping a socket according to some embodiments of the present disclosure. Although a fixing device (e.g., 300 of FIG. 8 ) is not depicted in FIG. 9 , it should be understood that the fixing device (300) grips a bearing (210) as shown in FIG. 8 .

[0111] Referring to FIG. 9, the rotating device (500) can move in a first direction (X), a second direction (Y), and a third direction (Z). Although not shown, the rotating device (500) can move in the first direction (X), the second direction (Y), and the third direction (Z) using a plurality of linear guides. The operation of the rotating device (500) does not interfere with the operation of the fixing device and the separating device.

[0112] A rotating device (500) can grip a socket (100). The rotating device (500) moves over a target socket (100), and a gripper (510) of the rotating device (500) can be placed on the socket (100). Then, the gripper (510) can apply pressure to the socket (100) in a first direction (X) to grip the socket (100). In this case, the first seating portion (SP1) of the socket (100) may be exposed.

[0113] FIG. 10 is a drawing for explaining the operation of a rotating device rotating a socket according to some embodiments of the present disclosure.

[0114] Referring to FIG. 10, the rotation device (500) can separate the socket (100) from the socket case (200) and rotate it. For example, the rotation device (500) can separate the socket (100) from the socket case (200) by moving it in a positive first direction (+X) or a negative first direction (-X). Here, the first direction (X) can be the same as the traveling direction of the moving belt.

[0115] Next, the rotating device (500) can rotate the socket (100) 180 degrees about the Y-axis. The socket (100) is rotated by the rotating device (500), so that the second mounting portion (SP2) of the socket (100) can be exposed. The first mounting portion (SP1) of the socket (100) can face the moving belt or the socket case (200).

[0116] Although not shown, in some embodiments, the rotation device (500) can move the socket (100) in a positive third direction (+Z) to separate it from the socket case (200). Here, the positive third direction (+Z) can be a direction orthogonal to the direction of travel of the moving belt. Subsequently, the rotation device (500) can rotate the socket (100) 180 degrees about the Y-axis as the rotation axis.

[0117] FIG. 11 is a drawing illustrating an operation of coupling a socket with a second mounting portion exposed to a socket case in some embodiments of the present disclosure.

[0118] Referring to FIG. 11, the rotating device (500) can move the socket (100) with the second mounting portion (SP2) exposed so as to align it on the socket case (200). For example, the rotating device (500) can move the socket (100) in the positive first direction (+X) so as to couple it to the socket case (200). As a result, the hole of the socket (100) and the hole of the socket case (200) can be aligned.

[0119] In some embodiments, the protruding line of the socket (100) may be engaged with the groove of the socket case (200). For example, when the rotating device (500) moves the socket (100) in the positive first direction (+X) to engage the socket case (200), the protruding line of the socket (100) may be engaged with the groove of the socket case (200).

[0120] Next, the separation device (400) can insert the joining member (220) into the hole of the socket case (200) and the hole of the socket (100). The joining member (220) can be inserted to prevent the socket (100) and the socket case (200) from being separated. Next, the separation device (400) can be separated from the joining member (220), and the fixing device (300) can be separated from the socket case (200) to complete the replacement of the socket (100).

[0121] For convenience of explanation, one of the pair of sockets (100) has been described. The description of the other socket (100) may be similar to that described above. After the pair of sockets (100) are each coupled to the socket case (200), a battery cell of a specific type (e.g., 20 in FIG. 3) corresponding to the second mounting portion (SP2) may be placed on the second mounting portion (SP2) of the socket (100).

[0122] In conventional battery cell logistics processes, different sockets are required to transport different types of battery cells. This necessitates the production of sockets specific to each battery cell, requiring manual replacement by workers, potentially increasing production time.

[0123] A secondary battery manufacturing system according to some embodiments of the present disclosure can replace a socket (100) with a first mounting portion (SP1) exposed so that a second mounting portion (SP2) is exposed, using a fixing device (300), a separating device (400), and a rotating device (500). Accordingly, different battery cells can be transported using a single socket (100). In addition, since the rotating device (500) automatically rotates and replaces the socket (100), the time required for replacing the socket (100) can be reduced. Accordingly, the production time of the secondary battery manufacturing process can be reduced, and the efficiency can be increased.

[0124] FIG. 12 is a flowchart illustrating a secondary battery manufacturing system according to some embodiments of the present disclosure. The socket illustrated in FIG. 12 may be the socket (100) illustrated in FIGS. 4 to 6 .

[0125] Referring to FIG. 12, the interest battery manufacturing system (1200) may be initiated by a fixing device gripping a socket case positioned on a moving belt (1210). For example, the fixing device may move toward and grip a bearing of the socket case. Subsequently, a separation device may separate a coupling member that couples the socket case and the socket (1220). A rotating device may grip a socket with a first mounting portion exposed (1230).

[0126] Next, the rotating device may rotate the socket to expose the second mounting portion of the socket (1240). For example, the rotating device may separate the socket from the socket case and rotate the socket 180 degrees around the rotation axis. In this case, the rotating device may separate the socket from the socket case in a direction parallel to or perpendicular to the direction of travel of the moving belt.

[0127] Next, the rotating device can couple the rotated socket to the socket case. As a result, the holes in the socket and the holes in the socket case can be aligned. Thereafter, the separating device can couple the coupling member to the socket and the socket case (1250). Subsequently, the separating device can be separated from the coupling member, and the fixing device can be separated from the socket case.

[0128] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various modifications and variations are possible within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below by a person having ordinary skill in the art to which the present invention pertains.
