Description

Technical Field

[0001] Some aspects of embodiments of this disclosure relate to a card holder and a method for manufacturing a secondary battery. Background Technology

[0002] A secondary battery is a rechargeable battery, meaning a battery capable of being charged and discharged multiple times. Such secondary batteries are primarily used in various applications such as electronic products (e.g., smartphones, laptops, and tablets), electric vehicles, photovoltaic power generation, and emergency power supplies. Specifically, lithium-ion batteries have high energy density and high charge / discharge efficiency, and are therefore used in various electronic products and electric vehicles.

[0003] The shape of a secondary battery varies depending on the product in which it is used. For example, the size of a secondary battery used in an electric vehicle differs from the size of one used in an electronic product. The manufacturing process of a secondary battery requires various holders to hold and move different batteries. Additionally, it necessitates changing the individual holders corresponding to different secondary batteries.

For example, the moving belt 32 can receive power and move in one direction together with the card holder housing 200 disposed on the moving belt 32. For example, the moving belt 32 may be a timing belt.

[0057] Guide rails 34 can be disposed on both sides of the moving belt 32. Bearings of the card holder housing 200 can be disposed on the guide rails 34. When the moving belt 32 moves in one direction, the bearings of the card holder housing 200 can rotate in one direction along the guide rails 34.

[0058] Card holder housings 200 can be mounted on the moving device 30. As shown, a pair of card holder housings 200 can be positioned facing each other. For example, a pair of card holder housings 200 can be positioned facing each other along the direction in which the moving belt 32 moves. The card holder housings 200 can be joined and fixed to the moving belt 32.

[0059] In some embodiments, the first type of battery cell 10 may be disposed on the card holder 100. For example, the first type of battery cell 10 may be disposed on a pair of card holders 100 arranged to face each other. The first type of battery cell 10 may be disposed on the card holder 100 or detached from the card holder 100 by a battery transfer robot.

[0060] In some embodiments, the first type of battery cell 10 may be a battery cell that has already undergone charge / discharge testing. However, this disclosure is not limited thereto.

The separating device 400 can engage or disengage the engaging members attached to the card holder 100 and the card holder housing 200. Although the fixing device 300 and the separating device 400 are shown as combined into one device, this disclosure is not limited thereto. For example, the fixing device 300 and the separating device 400 can be separate devices.

[0062] The rotating device 500 can be disposed on one side of the card holder 100. The rotating device 500 can clamp the card holder 100 and separate it from the card holder housing 200. The rotating device 500 can rotate the card holder 100 180 degrees about a rotation axis. For example, the rotating device 500 can rotate the card holder 100 180 degrees about a rotation axis, such that the first mounting portion of the card holder 100 is not exposed while the second mounting portion is exposed. (Refer to...) Figure 7 The operation of the fixing device 300, the separating device 400, and the rotating device 500 is described in detail.

[0063] Although the fixing device 300, the separating device 400, and the rotating device 500 are shown as being respectively mounted on different card holders 100, this illustration is for ease of description. Contrary to what is shown, the fixing device 300, the separating device 400, and the rotating device 500 may be mounted on the same card holder 100. For example, a fixing device, a separating device, and a rotating device corresponding to each card holder may be provided.

Figure 2 The differences between the content described in the text. For reference, Figure 3 The 100 cassette can be constructed by... Figure 2 The card holder 100 is obtained by rotating the card holder 100 around the rotation axis by 180 degrees. When the card holder 100 is rotated 180 degrees around the rotation axis, the first mounting part of the card holder 100 may not be exposed, but the second mounting part may be exposed.

[0068] Reference Figure 3 The second type of battery cell 20 can be disposed on a pair of card holders 100. The size of the second type of battery cell 20 can be different from that of the first type of battery cell 10. For example, the second type of battery cell 20 can be different from the first type of battery cell 10 in at least one aspect, such as width or length (or height, breadth).

[0069] Although the first type of battery cell 10 and the second type of battery cell 20 are shown as prismatic battery cells, this disclosure is not limited thereto. For example, the first type of battery cell 10 and the second type of battery cell 20 may be pouch-type battery cells, cylindrical battery cells, etc.

[0070] Figure 4 This is a perspective view showing a card holder according to some embodiments of the present disclosure. Figure 5This is a perspective view showing a card holder according to some embodiments of the present disclosure. For reference, Figure 5 The cassette 100 can have the following features: Figure 4 The shape is obtained by rotating the card holder 100 180 degrees around the Y-axis, which is the axis of rotation.

[0071] Reference Figure 4 The first direction X can refer to the X-axis direction. In an embodiment, the card holder 100 can move along the first direction X via a moving belt. The second direction Y can be orthogonal to the first direction X. The second direction Y can refer to the Y-axis direction. The third direction Z can be orthogonal to each of the first direction X and the second direction Y. The third direction Z can refer to the Z-axis direction.

The second direction Y can include a positive second direction +Y and a negative second direction -Y. The third direction Z can include a positive third direction +Z and a negative third direction -Z.

[0073] As shown, the positive first direction +X and the negative first direction -X can be opposite directions. The positive second direction +Y and the negative second direction -Y can be opposite directions. The positive third direction +Z and the negative third direction -Z can be opposite directions.

[0074] The card holder 100 may include a plate 110, a first wall 120, a second wall 150, a first side wall 130, a second side wall 140, a third side wall 160, a fourth side wall 170, a first mounting part SP1, and a second mounting part SP2.

[0075] Plate 110 can be positioned at the center of card holder 100. Plate 110 may include a first surface 110_S1 and a second surface 110_S2. First wall 120, first side wall 130 and second side wall 140 may be disposed on the first surface 110_S1 of plate 110.

[0076] The first wall 120 may be disposed at one end of the plate 110 (e.g., at the end in the negative first direction -X). The first wall 120 may extend from one end of the plate 110 along the positive third direction +Z. The first wall 120 may be connected to the plate 110.

[0077] Each of the first sidewall 130 and the second sidewall 140 may extend from both sides of the first wall 120 in one direction. For example, the first sidewall 130 may extend from one side of the first wall 120 in a positive first direction +X, and the second sidewall 140 may extend from the other side of the first wall 120 in a positive first direction +X. Each of the first sidewall 130 and the second sidewall 140 may be connected to the first wall 120 and the plate 110. The first sidewall 130 and the second sidewall 140 may face each other and be spaced apart in a second direction Y.

[0078] The first mounting portion SP1 may be defined by a first surface 110_S1 of the plate 110, a first wall 120, a first side wall 130, and a second side wall 140. The first mounting portion SP1 may include an open surface facing the first wall 120. For example, the open surface may be provided at the end of the first mounting portion SP1 in the positive first direction +X. Furthermore, the first mounting portion SP1 may include an open surface facing the plate 110. For example, the open surface may be provided at the end of the first mounting portion SP1 in the positive third direction +Z.

[0079] Reference Figure 5 The second wall 150 may be disposed on the second surface 110_S2 of the plate 110. The second wall 150 may be disposed at one end of the plate 110 (e.g., at the end in the positive first direction +X). The second wall 150 may extend from one end of the plate 110 along the negative third direction -Z. The second wall 150 may be connected to the plate 110.

[0080] Each of the third sidewall 160 and the fourth sidewall 170 may extend from both sides of the second wall 150 in one direction. For example, the third sidewall 160 may extend from one side of the second wall 150 along a negative first direction -X, and the fourth sidewall 170 may extend from the other side of the second wall 150 along a negative first direction -X. Each of the third sidewall 160 and the fourth sidewall 170 may be connected to the second wall 150. The third sidewall 160 and the fourth sidewall 170 may face each other and be spaced apart in a second direction Y.

[0081] The first sidewall 130 and the third sidewall 160 may be connected, and the second sidewall 140 and the fourth sidewall 170 may be connected. For example, a surface of the first sidewall 130 and a surface of the third sidewall 160 may be connected, and a surface of the second sidewall 140 and a surface of the fourth sidewall 170 may be connected. The first wall 120 and the second wall 150 may be spaced apart in the first direction X. Furthermore, the first wall 120 and the second wall 150 may not overlap in the third direction Z.

[0082] Unlike the illustration, in some embodiments, each of the first wall 120 and the second wall 150 may be located at one end of the plate 110. For example, the first wall 120 may extend from one end of the plate 110 (e.g., the end in the negative first direction -X) along the positive third direction +Z, and the second wall 150 may extend from said one end of the plate 110 along the negative third direction -Z. In this case, each of the open first surface facing the first wall 120 and the open second surface facing the second wall 150 may be located at the other end of the plate 110 (e.g., the end in the positive first direction +X).

[0083] The second mounting portion SP2 may be defined by the second surface 110_S2, the second wall 150, the third side wall 160, and the fourth side wall 170 of the plate 110. The second mounting portion SP2 may include an open surface facing the second wall 150. For example, the open surface may be provided at the end of the second mounting portion SP2 in the negative first direction -X. Furthermore, the second mounting portion SP2 may include an open surface facing the plate 110. For example, the open surface may be provided at the end of the second mounting portion SP2 in the negative third direction -Z.

[0084] Reference Figure 4 and Figure 5 The first mounting portion SP1 may have a first length D1 in the first direction X. Furthermore, the first mounting portion SP1 may have a first width W1 in the second direction Y. The first mounting portion SP1 may correspond to a first type of battery cell (e.g., Figure 2 (10 in the example). For example, the first width W1 may correspond to the width of the first type of battery cell 10.

[0085] The second mounting portion SP2 may have a second length D2 in the first direction X. Furthermore, the second mounting portion SP2 may have a second width W2 in the second direction Y. The second mounting portion SP2 may correspond to a second type of battery cell (e.g., Figure 3 (20 in the example). For example, the second width W2 can correspond to the width of the second type of battery cell 20.

[0086] In some embodiments, the first length D1 of the first mounting portion SP1 and the second length D2 of the second mounting portion SP2 may be different from each other. For example, the first length D1 of the first mounting portion SP1 may be less than the second length D2 of the second mounting portion SP2. In this case, the first width W1 of the first mounting portion SP1 may be equal to or different from the second width W2 of the second mounting portion SP2.

[0087] In some embodiments, the first length D1 of the first mounting portion SP1 and the second length D2 of the second mounting portion SP2 may be equal to each other. In this case, the first width W1 of the first mounting portion SP1 may be different from the second width W2 of the second mounting portion SP2.

[0088] In some embodiments, the volume of the first mounting portion SP1 may be different from the volume of the second mounting portion SP2. Here, the volume of each of the first mounting portion SP1 and the second mounting portion SP2 can be calculated as the product of the widths W1 and W2, the lengths D1 and D2, and the height of the mounting portions SP1 and SP2.

[0089] According to some embodiments of this disclosure, the card holder 100 may include a first mounting portion SP1 and a second mounting portion SP2. Therefore, different types of battery cells can be mounted on a single card holder 100. As a result, the manufacturing cost of the card holder 100 can be reduced. Furthermore, the space efficiency required for storage in the card holder 100 can be improved, thus improving the efficiency of the secondary battery manufacturing process.

[0090] In some embodiments, the card holder 100 may further include a protrusion 135. The protrusion 135 may be formed to protrude along a second direction Y on each of the first sidewall 130, second sidewall 140, third sidewall 160, and fourth sidewall 170. The protrusion 135 may extend in a first direction X. When the card holder 100 and the card holder housing are engaged, the protrusion 135 may fit into a recess in the card holder housing (e.g., Figure 2 (230) in the middle.

[0091] In some embodiments, unlike those shown, an inclined portion may be formed at one end of the protrusion 135. For example, the inclined portion may be formed at each of the ends of the protrusion 135 in the positive first direction +X and the negative first direction -X. When the card holder 100 is inserted into the card holder housing in the first direction X, the protrusion 135 can be easily inserted into the groove of the card holder housing through the inclined portion.

[0092] Figure 6 This is a perspective view showing a card holder according to some embodiments of the present disclosure. For ease of description, a brief description will be given. Figure 4 and Figure 5 The part described in the text is repeated.

[0103] Figures 7 to 11 A secondary battery manufacturing system according to some embodiments of the present disclosure is shown. For ease of description, the moving belt and guide rail are shown as excluded. The card holder 100 described below may be in... Figures 4 to 6 The card slot 100 described in the text.

[0104] Reference Figure 1 and Figure 7 A pair of card holder housings 200 can be installed on a mobile device (e.g., Figure 1 On (30) of the card holder housing. As shown, the card holder housings 200 can be configured to face each other. The card holder housing 200 may include a bearing 210 disposed on the outer side of the card holder housing 200. The bearing 210 may be disposed on a guide rail (e.g., Figure 1 34) above.

[0105] Card holder 100 can be coupled to each card holder housing 200. For example, a protrusion of card holder 100 can be coupled to a recess of card holder housing 200. As shown, card holders 100 can be configured to face each other. Card holders 100 can be configured such that the first mounting portion SP1 is exposed.

[0106] The engaging member 220 can be engaged with the card holder 100 and the card holder housing 200 to secure the card holder 100 and the card holder housing 200. For example, the engaging member 220 can be inserted into a groove formed on one surface of the card holder 100 and a groove formed on one surface of the card holder housing 200. The engaging member 220 can prevent the card holder 100 from separating from the card holder housing 200. For example, the engaging member 220 can be an indexing plunger.

[0107] Figure 8 The operation of the fixing device and the separating device according to some embodiments of the present disclosure is illustrated. Hereinafter, for ease of description, the description will focus on... Figure 7 The card holder 100 is located on the right side of a pair of card holders 100.

[0108] Reference Figure 8The fixing device 300 can clamp the card holder housing 200. Specifically, the fixing device 300 can move toward the bearing 210 of the card holder housing 200. Subsequently, the fixing device 300 can clamp the bearing 210 of the card holder housing 200. The fixing device 300 can prevent the card holder housing 200 from moving when the card holder 100 is separated from the card holder housing 200 or when the card holder 100 is engaged with the card holder housing 200.

[0109] Subsequently, the separating device 400 can separate the connecting member 220. Specifically, the separating device 400 can clamp the connecting member 220. Afterward, the separating device 400 can move the connecting member 220 in the negative second direction -Y to separate the connecting member 220 from the groove of the card holder 100 and the groove of the card holder housing 200.

[0110] Figure 9 The operation of the rotating device clamping holder according to some embodiments of the present disclosure is illustrated. Although in Figure 9 The fixing device is not shown in the figure (e.g., Figure 8 (300 in the text), but it should be understood that the fixing device 300, such as Figure 8 The bearing 210 is held in place in that manner.

[0111] Reference Figure 9 The rotating device 500 can move in the first direction X, the second direction Y, and the third direction Z. Although not shown, the rotating device 500 can be moved in the first direction X, the second direction Y, and the third direction Z by using multiple linear guides. The operation of the rotating device 500 does not interfere with the operation of the fixing device and the separating device.

[0112] The rotating device 500 can clamp the card holder 100. The rotating device 500 can be moved onto the target card holder 100, and the clamping member 510 of the rotating device 500 can be disposed on the card holder 100. Subsequently, the clamping member 510 can apply pressure to the card holder 100 in the first direction X to clamp the card holder 100. In this case, the first placement portion SP1 of the card holder 100 can be exposed.

[0113] Figure 10 The operation of the rotating device rotating the card holder according to some embodiments of the present disclosure is shown.

[0114] Reference Figure 10 The rotating device 500 can separate the card holder 100 from the card holder housing 200 and rotate the card holder 100. For example, the rotating device 500 can move the card holder 100 in the positive first direction +X or the negative first direction -X to separate the card holder 100 from the card holder housing 200. Here, the first direction X can be equal to the travel direction of the moving belt.

[0115] Subsequently, the rotating device 500 can rotate the card holder 100 by 180 degrees around the Y-axis, which serves as the rotation axis. When the card holder 100 is rotated by the rotating device 500, the second mounting portion SP2 of the card holder 100 can be exposed. The first mounting portion SP1 of the card holder 100 can face the moving belt or the card holder housing 200.

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

[0117] Figure 11 The operation of attaching a card holder with an exposed second mounting portion to a card holder housing according to some embodiments of the present disclosure is shown.

[0118] Reference Figure 11 The rotating device 500 can move the card holder 100 that exposes the second mounting portion SP2 to align the card holder 100 with the card holder housing 200. For example, the rotating device 500 can move the card holder 100 in the positive first direction +X to engage the card holder 100 with the card holder housing 200. As a result, the holes in the card holder 100 and the holes in the card holder housing 200 can be aligned.

[0119] In some embodiments, the protrusion of the card holder 100 may engage with the groove of the card holder housing 200. For example, when the rotating device 500 moves the card holder 100 in the positive first direction +X to engage the card holder 100 with the card holder housing 200, the protrusion of the card holder 100 may be fitted into the groove of the card holder housing 200.

[0120] Subsequently, the separating device 400 can insert the connecting member 220 into the holes of the card holder housing 200 and the card holder 100. When the connecting member 220 is inserted, it can prevent the card holder 100 and the card holder housing 200 from separating. Then, the separating device 400 separates from the connecting member 220, and the fixing device 300 separates from the card holder housing 200, thereby completing the replacement of the card holder 100.

[0121] For ease of description, one of the pair of card holders 100 has been described. The other card holder 100 can be described similarly to the above description. After the pair of card holders 100 are respectively attached to the card holder housing 200, a specific type of battery cell (e.g., corresponding to the second mounting portion SP2) is used. Figure 3 20) can be set on the second mounting part SP2 of the card holder 100.

[0122] In the conventional logistics process of battery cells, different card holders are required to transfer different types of battery cells. Therefore, it is necessary to manufacture a card holder corresponding to each battery cell, and because the changeover is performed manually by the operator, production time may increase.

[0123] According to some embodiments of the present disclosure, a secondary battery manufacturing system can switch the exposed first mounting portion SP1 of the holder 100 to expose the second mounting portion SP2 by using a fixing device 300, a separating device 400, and a rotating device 500. Therefore, different battery cells can be transferred using a single holder 100. Furthermore, since the rotating device 500 automatically rotates the holder 100 to switch the holder 100, the time required to switch the holder 100 can be reduced. Therefore, the production time of the secondary battery manufacturing process can be reduced, and efficiency can be improved.

[0124] Figure 12 This is a flowchart illustrating a method for manufacturing a secondary battery according to some embodiments of the present disclosure. Figure 12 The booth described in the text can be Figures 4 to 6 The card slot 100 described in the text.

[0125] Reference Figure 12 In operation 1210, secondary battery manufacturing 1200 can begin when the fixing device clamps the card holder housing disposed on the moving belt. For example, the fixing device can move toward and clamp the bearing of the card holder housing. Subsequently, in operation 1220, the separating device can separate the connecting member that binds the card holder housing and the card holder. In operation 1230, the rotating device can clamp the card holder that exposes the first mounting portion.

[0126] Subsequently, in operation 1240, the rotating device can rotate the card holder, exposing the second mounting portion of the card holder. For example, the rotating device can separate the card holder from the card holder housing and rotate the card holder 180 degrees about the rotation axis. In this case, the rotating device can separate the card holder from the card holder housing in a direction equal to or perpendicular to the travel direction of the moving belt.

[0127] Subsequently, the rotating device can engage the rotated card holder to the card holder housing. As a result, the holes in the card holder and the card holder housing can be aligned. Then, in operation 1250, the separating device can engage the engaging member to the card holder and the card holder housing. Subsequently, the separating device separates from the engaging member, and the fixing device can separate from the card holder housing.

[0128] Although the present disclosure has been described above with reference to limited embodiments and accompanying drawings, the present disclosure is not limited thereto, and various modifications and variations can be made by those skilled in the art within the scope of the technical concept of the present disclosure and the equivalents of the appended claims.
