[0057] First Implementation Method

[0058] Figure 1 This is a conceptual diagram of a battery testing device IS-0 based on a comparative example of this disclosure.

[0059] Reference Figure 1 The following describes a battery testing device IS-0 according to a comparative example of this disclosure.

[0060] like Figure 1 As shown, a battery testing device IS-0 can be provided for testing secondary battery B.

[0061] The secondary battery B can be cylindrical. However, the secondary battery B can be prismatic or pouch-shaped if necessary. The battery testing device IS-0 according to the comparative example can have space for testing the secondary battery B. Therefore, when the secondary battery B is placed inside the battery testing device IS-0, the battery testing device IS-0 can test the secondary battery B.

[0062] The battery testing device IS-0 may include an electromagnetic wave transmitter device 100 and an electromagnetic wave detector device 200. The electromagnetic wave transmitter device 100 may be configured to emit electromagnetic waves toward the secondary battery B. Here, electromagnetic waves may refer to X-rays. However, the electromagnetic waves may be visible light if necessary, and correspondingly, the electromagnetic wave detector device 200 may be a visual camera. Furthermore, the secondary battery B can be tested by the naked eye instead of the electromagnetic wave transmitter device 100 and the electromagnetic wave detector device 200. Electromagnetic waves, such as X-rays, may travel through specific portions of the secondary battery B. The electromagnetic waves emitted from the electromagnetic wave transmitter device 100 may be directed toward the electromagnetic wave detector device. The electromagnetic wave detector device 200 can detect defects or foreign objects in the secondary battery B by detecting electromagnetic waves that have passed through and those that have not yet passed through the secondary battery B. More specifically, when the signals measured by the electromagnetic wave detector device are analyzed by the control unit, the internal structure of the secondary battery B can be identified through signal analysis, and defects in the secondary battery B can be identified through the identified structure. For example, this measurement method can be called computed tomography (CT).

[0063] In this case, the configuration of the secondary battery B in only one direction can be identified by electromagnetic waves emitted in one direction. To detect all internal defects of the entire secondary battery B, it is necessary to observe the interior of the secondary battery B from different directions. For this purpose, the secondary battery B can be rotated in place, and electromagnetic waves can be emitted towards the rotating secondary battery B, allowing the electromagnetic wave detector device 200 to detect the interior of the secondary battery B from different angles.

[0064] However, this method requires a detection time after moving the secondary battery B to the designated position, which increases the manufacturing time of the secondary battery B. In particular, because the CT method requires a significant amount of detection time, it is necessary to reduce the required time.

[0065] In the following, a battery manufacturing system MS according to a first embodiment of the present disclosure will be described, which is designed to solve the above-mentioned problems. It should also be noted that the secondary battery B, the electromagnetic wave detection device, and the electromagnetic wave detector 200 described above are also applicable to the first embodiment of the present disclosure described below.

[0066] Figure 2 This is a perspective view of the secondary battery B and the rotational force transmitter 300 included in the battery testing device IS according to the first embodiment of this disclosure. Figure 3 yes Figure 2 A perspective view of the rotational force transmitter 300 shown. Figure 4 It includes having Figure 2 The diagram shows a concept diagram of a battery manufacturing system MS for a battery testing device IS with a rotary force transmitter 300.

[0067] Reference Figures 2 to 4 The present invention will describe a battery manufacturing system MS including a battery testing device IS according to a first embodiment of the present disclosure.

[0068] According to the first embodiment of this disclosure, the battery testing device IS can be configured to test the secondary battery B during the movement of the secondary battery B from the first manufacturing device 10 to the second manufacturing device 20, such as... Figure 4As shown. In other words, the battery manufacturing system MS may include: a first manufacturing device 10 and a second manufacturing device 20, the first manufacturing device 10 being configured to process a secondary battery B, and the second manufacturing device 20 being spaced apart from the first manufacturing device 10 and configured to process the secondary battery B after processing by the first manufacturing device 10. Additionally, a battery detection device IS may be located between the first manufacturing device 10 and the second manufacturing device 20 to detect the secondary battery B during the movement of the secondary battery B from the first manufacturing device 10 to the second manufacturing device 20. Furthermore, the first manufacturing device 10 may be configured to perform an activation step, and the second manufacturing device 20 may be configured to perform a packaging step of the secondary battery B. However, the first manufacturing device 10 and the second manufacturing device 20 are not limited to this, and may perform adjacent steps.

[0069] As described above, the battery testing device IS may include an electromagnetic wave transmitter device 100 and an electromagnetic wave detector device 200. The electromagnetic wave transmitter device 100 is configured to emit electromagnetic waves toward the secondary battery B, and the electromagnetic wave detector device 200 is configured to detect the electromagnetic waves passing through the secondary battery B. Furthermore, the battery testing device IS may also include a rotational force transmitter 300, which is configured to be connected to the secondary battery B. The rotational force transmitter 300 is not a component connected to the secondary battery B and fixedly located in a predetermined space, but can be conceptually understood as a component of the battery testing device IS. The battery testing device IS may also include a main moving device 400, which is configured to apply pressure to the rotational force transmitter 300 to cause the secondary battery B to rotate and move about the battery movement direction during the period when the electromagnetic wave detector device 200 detects the electromagnetic waves passing through the secondary battery B. In other words, through the interaction between the main moving device 400 and the rotational force transmitter 300, the secondary battery B can be rotated and moved. During the rotation and movement of the secondary battery B, the electromagnetic wave transmitter device 100 can emit electromagnetic waves in different directions of the secondary battery B, and the electromagnetic wave detector device 200 can detect the electromagnetic wave information in each direction of the secondary battery B.

[0070] In this case, the main moving device 400 may not directly apply pressure to the secondary battery B. When the main moving device 400 directly applies pressure to the secondary battery B, it may damage the appearance of the secondary battery B, thereby increasing the defect rate of the secondary battery B. To prevent this, the rotational force transmitter 300 may be configured to allow the main moving device 400 to indirectly transmit power to the secondary battery B.

[0071] The interaction between the main moving device 400 and the rotational force transmitter 300 will be described in more detail below.

[0072] First, the rotational force transmitter 300 will be described. For example... Figure 2 and Figure 3 As shown, the rotational force transmitter 300 may include a pair of rotational force transmitters, and the pair of rotational force transmitters 300 may each be connected to each of the two ends in the extension direction of the rotational axis of the secondary battery B. Figure 2 As shown, the rotational force transmitter 300 can be connected to each of the top and bottom of the secondary battery B. However, the rotational force transmitter 300 can be located further inward than the end of the secondary battery B if necessary.

[0073] The rotational force transmitter 300 may include a transmitter body 310 and a toothed gear 320.

[0074] The transmitter body 310 can be formed into a cylindrical shape to conform to the shape of the secondary battery B. That is, the transmitter body 310 can have a shape other than a cylindrical shape to conform to the shape of the secondary battery B if necessary. The transmitter body 310 can have a battery receiving groove 311H conforming to the shape of the secondary battery B. Here, the battery receiving groove 311H can be a hole, regardless of its name. Figure 2 As shown, the transmitter body 310 can be directly connected to the upper and / or lower end of the secondary battery B. The secondary battery B can be accommodated within the battery receiving groove 311H and connected to the transmitter body 310. Here, the rotational force transmitter 300, i.e., the transmitter body 310, can be connected to the secondary battery B via an interference fit. That is, the inner diameter of the battery receiving groove 311H can be slightly smaller than the outer diameter of the secondary battery B to fix the transmitter body 310 and the secondary battery B relative to each other. However, the method of fixing the secondary battery B and the transmitter body 310 can include any other method if necessary, such as grooves and protrusions.

[0075] like Figure 4 As shown, the rotational force transmitter 300 may include a toothed gear 320 projecting toward the main moving device 400. This toothed gear 320 may protrude from the transmitter body 310, such as... Figure 3 As shown. The toothed gear 320 can be integrally formed with the conveyor body 310. However, if necessary, the toothed gear 320 and the conveyor body 310 can be separate components, and the toothed gear 320 can be coupled to the conveyor body 310 to prevent rotation relative to each other. The toothed gear 320 can be arranged around the outer periphery of the conveyor body 310. That is, the toothed gear 320 can include multiple toothed gears, and the multiple toothed gears 320 can be arranged along the circumferential direction of the conveyor body 310. The spacing of the multiple toothed gears 320 can be set such that the toothed gears 320 mesh with the main gear meshing portion 410 of the main moving device 400 described below.

[0076] like Figure 4 As shown, the main moving device 400 may include a main gear meshing portion 410, which is configured to mesh with a toothed gear 320. Although Figure 4 Only the main gear engagement portion 410 of the main moving device 400 is shown, but the main moving device 400 may also include components (not shown) for transmitting power to the main gear engagement portion 410 or include a housing (not shown). Additionally, the main moving device 400 may, if necessary, include components of a different shape that interact with the rotational force transmitter 300. (See reference...) Figure 7 The fourth embodiment is described in more detail.

[0077] In this case, the main gear meshing portion 410 can be configured to move in the same direction as the battery movement direction. For example... Figure 4 As shown, during the movement of the secondary battery B to the right or upward, the main gear meshing portion 410 can move to the right or upward along with the secondary battery B. In this case, through the interaction between the main gear meshing portion 410 and the toothed gear 320 of the rotational force transmitter 300, the rotational force transmitter 300 can rotate and move along with the movement of the main gear meshing portion 410. As the rotational force transmitter 300 rotates and moves, the secondary battery B connected to the rotational force transmitter 300 can rotate and move.

[0078] The battery testing equipment IS may also include a secondary moving device 500, which is located on the side opposite to the main moving device 400 with respect to the secondary battery B, and is configured to support the secondary battery B. Figure 4 As shown, the auxiliary moving device 500 and the main moving device 400 can support the secondary battery B on opposite sides.

[0079] The main moving device 400 and the auxiliary moving device 500 can extend along the direction of battery movement. Therefore, during the movement of the secondary battery B, the main moving device 400 and the auxiliary moving device 500 can guide the secondary battery B to move along a predetermined path.

[0080] The auxiliary moving device 500 may include a secondary gear meshing portion 510, which is configured to mesh with the toothed gear 320 on the side opposite to the primary gear meshing portion 410. Therefore, the secondary gear meshing portion 510 can assist the rotation and movement of the rotational force transmitter 300.

[0081] In this case, the secondary gear meshing portion 510 can move in the opposite direction to the primary gear meshing portion 410. As the primary gear meshing portion 410 and the secondary gear meshing portion 510 move in opposite directions, the rotational force transmitter 300 can be rotated.

[0082] In this configuration, the electromagnetic wave transmitter device and the electromagnetic wave detector device 200 can be positioned facing each other outside the main moving device 400. This allows the electromagnetic wave detector device 200 to receive electromagnetic waves emitted from the electromagnetic wave transmitter device 100.

[0083] In particular, such as Figure 4 As shown, when the secondary battery B moves along a curved path, the electromagnetic wave detector device 200 can be located on the side with the longer path length. Based on Figure 4 Since the right path of the secondary battery B is longer than the left path, the electromagnetic wave detector 200 can be located on the right path, while the electromagnetic wave transmitter 100 can be located on the left path on the opposite side. The electromagnetic wave detector 200 can be positioned over a wider area to more sensitively measure electromagnetic waves, thereby improving measurement accuracy.

[0084] In the following description, embodiments different from the first embodiment will be described. Descriptions common to the first embodiment and other embodiments are omitted, and the other embodiments will be described based on the differences. In other words, it is obvious that necessary details not described in other embodiments can be supplemented by the description of the first embodiment.

[0087] Reference Figure 5 The present invention will describe a battery manufacturing system MS-1 including a battery testing device IS-1 according to a second embodiment of the present disclosure.

[0088] The second embodiment differs from the first embodiment in that each of the main gear meshing portion 410-1 of the main moving device and the secondary gear meshing portion 510-1 of the secondary moving device 500-1 forms a loop path, and the main moving device includes a main moving box 401-1, while the secondary moving device includes a secondary moving box 501-1.

[0092] The third embodiment differs from the first embodiment in that the auxiliary moving device 500-2 does not include the auxiliary gear meshing part 510.

[0093] As long as the auxiliary moving device 500-2 serves to prevent the secondary battery B from deviating from its path, the auxiliary moving device 500-2 can be configured to support the secondary battery B and may not include components that engage with the rotational force transmitter 300.

[0094] Fourth Implementation Method

[0095] Figure 7 This is a conceptual diagram of the battery manufacturing system MS-3 according to the fourth embodiment of this disclosure.

[0096] Reference Figure 7 The present disclosure will describe a battery manufacturing system MS-3 that includes a battery testing device IS-3 according to a fourth embodiment of the present disclosure.

[0097] The fourth embodiment differs from the first embodiment in that neither the auxiliary moving device 500-3 nor the main moving device 400-3 includes components for engagement.

[0098] In this case, the rotary force transmitter 300-3 can have a surface for increasing friction without gears. In this case, the auxiliary moving device 500-3 and the main moving device 400-3 can use friction to transmit force to the rotary force transmitter 300-3, so as to allow the rotary force transmitter 300-3 to rotate.

[0101] Reference Figure 8 The present disclosure will describe a battery manufacturing system including the battery testing device IS-4 according to the fifth embodiment of the present disclosure.

[0102] The fifth embodiment differs from the first embodiment in that it only has a main moving device, which supports the secondary battery B below the secondary battery B and includes a worktable 420-4 configured to support the main gear meshing portion 410-4.

[0103] Sixth Implementation Method

[0105] Reference Figure 9The following describes a rotational force transmitter 300 according to a sixth embodiment of the present disclosure.

[0106] The sixth embodiment differs from the first embodiment in that the rotational force transmitter 300 has a magnet 330 housed in a battery housing groove 311H, and the rotational force transmitter 300 is magnetically coupled to the secondary battery B through the magnet 330.
