Description

Technical Field

[0001] The present disclosure relates to an automatic separation jig for manufacturing a battery module, and more particularly to a jig capable of automatically disconnecting a connection between a connector of a sensing electrical component of a battery module and an inspection board with a single touch in a battery module manufacturing process. Background Art

[0002] Unlike non-rechargeable primary batteries, secondary batteries refer to batteries that can be charged / discharged, and are applied not only to portable devices but also to electric vehicles (EV, electric vehicle) and hybrid vehicles (HEV, hybrid electric vehicle) driven by an electric drive source.

[0003] At present, widely used secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, etc. The operating voltage of a unit secondary battery cell (i.e., a unit battery cell) is about 2.5V to 4.2V. Therefore, when a higher output voltage is required, a plurality of battery cells can be connected in series to construct a battery pack. In addition, according to the required charge / discharge capacity of the battery pack, a plurality of battery cells can be connected in parallel to construct a battery pack. Therefore, the number of battery cells included in the battery pack can be set differently according to the required output voltage or charge / discharge capacity.

[0004] When a battery pack is constructed by connecting a plurality of battery cells in series / parallel, a battery module including at least one battery cell (preferably a plurality of battery cells) is generally constructed first, and then a battery pack is constructed using at least one such battery module and adding other components. Here, a battery module refers to an assembly in which a plurality of battery cells are connected in series or in parallel, and a battery pack refers to an assembly in which a plurality of battery modules are connected in series or in parallel to increase capacity and output.

[0005] The battery module is equipped with electrical components (FPCB, ICB) for sensing voltage, temperature, etc. In order to inspect products in the battery module manufacturing process, it is necessary to assemble a connector 41 for sensing the electrical components and an inspection board 50 of a production line equipment.

[0006] Figure 1 The figure illustrates a state where the connector 41 of the sensing electrical component in the conventional battery module is connected to the inspection plate. Figure 2 is an example Figure 1 FIG. 4 is a diagram showing a state in which the connector 41 of the sensing electrical component is separated from the inspection board 50 .

[0007] As illustrated in the figure, the connector 41 of the sensing electrical component in the existing battery module is configured with a hook structure to prevent the connector from being separated due to vibration or impact on site, or is configured with a device that adopts such a way that the connector 41 is press-fitted and not easily loosened.

[0008] Therefore, in the production line, after the final EOL inspection of the product, it is difficult to remove the connector 41 of the sensing electrical component from the connector 51 of the inspection board 50. Problems arise due to the narrow space between the inspection board 50 and the connector 41 of the product, the difficulty of the connector removal work, and the damage to the physically weak electrical component. Summary of the invention

[0020] In addition, a plurality of the button rods are spaced apart and disposed on a guide seat; and the insertion hole is formed as a plurality of insertion holes so that each of the sliding units is inserted into the insertion hole.

[0021] In addition, the insertion hole is formed from one side surface of the guide base to an opposite side surface of the guide base.

[0022] In addition, the insertion hole has an inclined surface at the bottom thereof which is inclined downward, so that the sliding unit moves forward and downward when sliding.

[0023] In addition, the guide base further includes an insertion groove, which is located on a side surface where the button unit is disposed.

[0024] In addition, the insertion groove communicates with one end of the insertion hole.

[0025] In addition, an automatic separation jig for manufacturing the battery module is provided on the inspection plate.

In contrast, when a component is referred to as "directly under another component", there are no intermediate components.

[0048] Before describing the automatic separation jig 1000 for manufacturing a battery module according to aspects of the present disclosure, reference will be made to Figures 3 to 5 The structure of the battery module 1 is described as follows.

[0049] The battery module 1 may include a plurality of battery cells 10 , a module case 20 , and a plurality of bus bars 30 , and may further include a sensing unit 40 connected to the bus bars 30 and for sensing a voltage and a temperature of each battery cell.

[0050] The battery cell 10 may be a cylindrical battery cell 10 in which an electrode assembly is embedded in a metal can. The cylindrical battery cell 10 may be configured to include: a battery can 11, which is mainly made of a lightweight conductive metal material such as aluminum in a cylindrical shape; a jellyroll type electrode assembly, which is accommodated in the battery can 11; and a top cap, which is coupled to an upper portion of the battery can 11. The top cap is connected to the positive electrode tab of the electrode assembly to serve as a positive terminal, and the battery can 11 is connected to the negative electrode tab of the electrode assembly to serve as a negative terminal.

[0051] The cylindrical battery cells 10 may be inserted and disposed in the module case 20 , and the cylindrical battery cells 10 are joined to the bus bars 30 in a predetermined pattern through wires to be connected to each other in series and / or in parallel.

[0052] The battery cells applied to the battery module 1 are not necessarily limited to the cylindrical battery cells 10. For example, the battery module 1 according to aspects of the present disclosure may be configured using can-type battery cells having a rectangular parallelepiped shape or other shapes other than a cylindrical shape in the battery can 11.

[0053] The module case 20 is a structure for accommodating and fixing the battery cells 10 therein to protect the battery cells 10 from external shock or vibration, and may be configured to include a cell bottom frame 22 and a cell top frame 21 .

[0054] The cell bottom frame 22 may be configured to have a cell insertion hole inside an outer frame in a rectangular box shape, and the battery cells 10 are inserted into the cell insertion hole one by one. Figure 4 As shown, the battery cell 10 can be inserted and arranged in each battery cell insertion hole so that the top cap faces upward and the lower area (i.e., the bottom of the battery can 11) faces downward. Herein, the battery cell insertion hole is configured to penetrate the bottom surface of the battery cell bottom frame 22. Therefore, the bottom of the battery can 11 of the battery cell 10 can be exposed below the bottom surface of the battery cell bottom frame 22. Although not illustrated in the drawings, it can also be configured so that a thermally conductive pad with insulation is attached to the bottom surface of the battery cell bottom frame 22, and a cooling plate or a heat sink (including a refrigerant) is attached to the other surface of the thermally conductive pad, thereby absorbing the heat of the cylindrical battery cell 10.

[0055] The cell bottom frame 22 may be securely coupled to the cell top frame 21 by long bolts (not shown) together with hook fasteners.

[0056] The cell top frame 21 may cover an upper region of the battery cell 10 and may be configured to be coupled to the cell bottom frame 22 .

[0057] For example, the cell top frame 21 may have a cell socket (not shown) that matches the cell insertion hole of the cell bottom frame 22 up and down. When the cell top frame 21 and the cell bottom frame 22 are coupled, the battery cell 10 may be introduced into the cell socket from the top cap so that the upper area of ​​the entire battery cell 10 may be covered by the cell top frame 21.

[0058] In addition, the cell top frame 21 may include an upper surface portion covering the top of the entire battery cell 10 and four side portions that form a wall around the outside of the entire battery cell 10 together with the cell bottom frame 22, wherein Figure 5 As illustrated, the upper surface portion of the cell top frame 21 has a plurality of holes 21 a and seating grooves 21 b. A side surface plate 23 may be coupled to the side surface portion of the cell top frame 21.

[0059] The hole 21 a has a configuration in which the cell top frame 21 is partially perforated so that the top cap of the battery cell 10 or the upper end of the battery can 11 is partially exposed to the outside.

[0060] like Figure 4 As illustrated, the cell bottom frame 22 may be configured such that the battery cells 10 form a plurality of rows along the X-axis or Y-axis direction of the module housing 20 when the battery cells 10 are inserted therein. When such battery cells 10 are covered by the cell top frame 21, the top caps of the respective battery cells 10 or the upper ends of the battery cans 11 are partially exposed to the outside.

[0061] The hole 21a is used as a path for connecting the battery cell 10 located inside the module case 20 to the bus bar 30 located outside the module case 20 through a metal wire. For example, the bus bar 30 may be connected to the top cap or the upper end of the battery can 11 exposed through the hole 21a through the metal wire. For example, a wire bonding method of ultrasonically welding one end of the metal wire to the top cap or the upper end of the battery can 11 and ultrasonically welding the other end of the metal wire to the bus bar 30 may be adopted.

[0062] The seating grooves 21b are where the bus bars 30 are to be seated and fixed, and may extend along the length direction (Y-axis direction) of the module case 20 to be arranged at predetermined intervals in the width direction (X-axis direction) of the module case 20. The bus bars 30, which are straight metal conductors having the same left-right width, may be arranged in the respective seating grooves 21b.

[0063] The bus bar 30 has substantially the same left-right width as the seating groove 21 b , so that movement thereof in the width direction (X-axis direction) can be prevented.

[0064] In addition, the bus bar 30 may be provided in the form of a pin or a column formed to protrude from the surface (in the Z-axis direction) of the seating groove 21b, and may have a pin hole provided to insert the pin of the seating groove 21b into the bus bar 30. Therefore, the pin of the seating groove 21b is inserted into the pin hole of the bus bar 30, thereby preventing it from moving.

[0065] In the battery module 1 , the sensing unit 40 is an electrical component for sensing voltage, temperature, etc., and may include a sensing board.

[0066] In order to inspect the product in the battery module manufacturing process, it is necessary to assemble the connector 41 of the sensing electrical component and the inspection plate 50 of the production line equipment. The connector 41 of the sensing electrical component is provided with a hook structure to prevent the connector 41 from being separated due to vibration or impact on site, or is provided with a device that is not easily loosened in such a way that the connector 41 is press-fitted.

[0067] Therefore, in the production line, after the final EOL inspection of the product, it is difficult to remove the connector 41 of the sensing electrical component from the connector 51 of the inspection board 50. Problems arise due to the narrow space between the inspection board 50 and the connector 41 of the product, the difficulty of the connector removal work, and the damage to the physically weak electrical component.

[0068] In order to solve the problems associated therewith, aspects of the present disclosure are directed to providing an automatic separation jig 1000 for manufacturing a battery module to solve the problems caused by a connector releasing work which is essential for an EOL functional inspection in a battery module manufacturing process.

[0069] Figure 6 is a perspective view of an automatic separation fixture according to aspects of the present disclosure. Figure 7 yes Figure 6 A perspective view of the button lever in FIG. Figure 8 yes Figure 7 Bottom perspective view of the illustrated push button stem. Fig. 9 is a diagram illustrating a state in which an automatic separation jig according to an aspect of the present disclosure is placed on an inspection plate. Fig.10 is a cross-sectional view illustrating a state in which a connector of a sensing unit is connected to an inspection board when an automatic detaching jig according to an aspect of the present disclosure is mounted on the inspection board. Fig.11 is a cross-sectional view illustrating a state in which a connector of a sensing unit is separated from an inspection board by an automatic separation jig according to an aspect of the present disclosure. Fig.12 is a perspective view showing a state in which the connector of the sensing unit has been completely separated from the inspection board.

[0070] The automatic separation jig 1000 for manufacturing a battery module according to aspects of the present disclosure may include a plurality of button levers 100 and a guide seat 200 to which the button levers 100 are coupled.

[0071] The button lever 100 is a one-touch type button lever 100 for separating the connector 41 of the sensing unit 40 from the inspection board 50 through a one-touch operation, and may include a button unit 110 and a slide unit 120 .

[0072] The button unit 110 is used to move the slide unit 120 to release the connection of the connector 41. Fig.11 When the button unit 110 is pressed in the illustrated arrow direction, the sliding unit 120 may move to release the connection of the connector 41. The plurality of button units 110 may be each located in the insertion groove 220 of the guide base 200.

[0073] The sliding unit 120 is used to release the connection of the connector 41 from the inspection plate 50 by manipulating the button unit 110. The sliding unit 120 extends forward from the lower portion of the button unit 110 and is inserted into the insertion hole 210 of the guide seat 200. By manipulating the button unit 110, the sliding unit 120 can slide into the insertion hole 210 to release the connection of the connector 41.

[0074] The sliding unit 120 may include a connector pressing rib 121 and a hook pressing unit 122 .

[0075] like Figure 8 As illustrated, the connector pressing ribs 121 protrude downward on both sides of the lower surface of the sliding unit 120 and extend in the length direction. The sliding unit 120 may be used to press the connector 41 when sliding in the insertion hole 210 of the guide seat 200 .

[0076] like Figure 8 As illustrated, the hook pressing unit 122 protrudes downward from the front of the lower surface of the sliding unit 120. The sliding unit 120 may be used to press the hook 42 of the connector 41 while sliding within the insertion hole 210 of the guide seat 200.

[0077] The sliding unit 120 may be integrally formed with the button unit 110 .

[0078] The material of the button lever 100 in this regard may be made of synthetic resin, or may be made of other materials.

[0079] In this regard, four button levers 100 coupled to the guide base 200 are exemplified, but the number of the button levers 100 may vary.

[0080] The guide seat 200 is coupled to the button lever 100 and guides movement of the button lever 100 according to manipulation of the button unit 110 , and may include an insertion hole 210 into which the sliding unit 120 of the button lever 100 is inserted and an insertion groove 220 in which the button unit 110 of the button lever 100 is located.

[0081] The insertion hole 210 of the guide base 200 is where the sliding unit 120 of the button lever 100 is inserted. Four insertion holes 210 may be formed to be spaced apart from each other in the length direction of the guide base 200 in the same number as the button lever 100 .

[0082] As illustrated, the insertion hole 210 may be formed to penetrate from one side of the guide seat 200 to the other side, and the sliding unit 120 of the button lever 100 may be inserted into one end of the insertion hole 210 , and an end of the sliding unit 120 may protrude to the other end of the insertion hole 210 .

[0083] Then, the sliding unit 120 of the button lever 100 may be located at the bottom of the insertion hole 210, and the insertion hole 210 guiding the movement of the sliding unit 120 may be formed to be inclined downward in the forward direction of the sliding unit 120 relative to the bottom of the guide seat 200. The bottom of the insertion hole 210 may have an inclined surface 211.

[0084] Therefore, when the button rod 100 moves forward inside the insertion hole 210, as shown in FIG. Fig.10 and Fig.11 As shown, the sliding unit 120 moves along the inclined surface 211 which is inclined downward, so that the sliding unit 120 can also gradually move downward while moving forward.

[0085] The insertion groove 220 of the guide base 200 is where the button unit 110 of the button lever 100 is inserted. Four insertion grooves 220 may be formed to be spaced apart from each other in the length direction of the guide base 200 in the same number as the button lever 100 .

[0086] As illustrated, the insertion groove 220 may be formed to be recessed inwardly on one side of the guide base 200 , and the insertion groove 220 may communicate with one end of the insertion hole 210 .

[0087] Therefore, the sliding unit 120 of the button lever 100 may be inserted into the insertion hole 210 , and the button unit 110 may be located within the insertion groove 220 .

[0088] In addition, the guide base 200 may have a fastening hole 201. As illustrated, the fastening hole 201 is formed to penetrate the top and bottom of the guide base 200, and is used to fix the guide base 200 using a fixing bolt (not shown). The fixing bolt can be inserted into the fastening hole 201, and the inserted fixing bolt can be fastened to the inspection plate 50, so that the automatic separation jig 1000 can be fixed to the inspection plate 50.

[0089] Next, a method of operating the automatic separation jig 1000 having the above-described configuration for manufacturing a battery module according to aspects of the present disclosure will be described.

[0090] First, the automatic separation jig 1000 for manufacturing a battery module according to an aspect of the present disclosure is set on the inspection plate 50 of the production line equipment. Specifically, as Fig. 9 As shown, the automatic separation clamp 1000 can be set on the inspection plate 50 so that the connector 51 of the inspection plate 50 is located in the lower groove 230 formed in the lower part of the automatic separation clamp 1000, and the automatic separation clamp 1000 can be fixed to the inspection plate 50 by fastening the fixing bolt inserted into the fastening hole 201 to the inspection plate 50.

[0091] In addition, in order to inspect the battery module 1, the connector 41 of the sensing unit 40 in the battery module 1 may be coupled to the connector 51 of the inspection board 50. Specifically, the hook 42 of the connector 41 in the sensing unit 40 may be caught and fixed to the connector 51 of the inspection board 50. Fig.10 As illustrated, when the connector 41 of the sensing unit 40 is inserted into the connector 51 of the inspection board 50 , the connector 41 of the sensing unit 40 pushes the button lever 100 so that the button lever 100 may be located at a correct position.

[0092] In this way, after the final inspection is completed with the connectors 41 of the sensing unit 40 connected to the connectors 51 of the inspection board 50 , the respective connectors 41 of the sensing unit 40 may be separated from the connectors 51 of the inspection board 50 .

[0093] When the connector 41 of the sensing unit 40 and the connector 51 of the inspection plate 50 are separated, in the automatic separation jig 1000, the operator can move his finger along the Fig.11 The button unit 110 of the button lever 100 is pressed in the illustrated arrow direction.

[0094] Then, the button lever 100 moves forward, and the sliding unit 120 of the button lever 100 is guided to the insertion hole 210 of the guide seat 200 and moves forward. Then, the sliding unit 120 can move forward and gradually move downward by moving along the inclined surface 211 that is inclined downward and shapes the bottom of the insertion hole 210.

[0095] As the sliding unit 120 gradually moves downward, the hook pressing unit 122 formed on the lower surface of the sliding unit 120 presses the hook 42 of the connector 41, thereby releasing the fixation of the connector 41 of the sensing unit 40 and the connector 51 of the inspection board 50. Then, as the sliding unit 120 moves forward, the sliding unit 120 pushes the connector 41 of the sensing unit 40, so that the connector of the sensing unit can be completely separated from the connector 51 of the inspection board 50.

[0096] Fig.12 is a perspective view showing a state in which the connector of the sensing unit has been completely separated from the inspection board.

[0097] Therefore, in aspects of the present disclosure, when the operator presses the button unit 110 in the one-touch method as described above, the slide unit 120 of the button lever 100 presses the hook 42 of the connector 41, and the connector 41 is separated from the inspection plate 50. Therefore, it is possible to eliminate a defect source during a connector disassembly operation in an inspection process for manufacturing a battery module, solve a safety problem caused by damage to an electrical component, and reduce production losses and costs by improving workability.

[0098] Next, an automatic separation jig according to a second aspect of the present disclosure will be described. Fig.13 is a perspective view of an automatic separation fixture according to another aspect of the present disclosure. Fig.14 yes Fig.13 A perspective view of the button lever in FIG. Fig.15 It shows that Fig.13 A cross-sectional view of a state in which a connector of a sensing unit is connected to an inspection board when the illustrated automatic separation jig is placed on the inspection board.

[0099] The automatic separation clamp 1000 according to the second aspect of the present disclosure is different from the automatic separation clamp of the first aspect in that the sliding protrusion 125 is arranged on the two side surfaces of the sliding unit 120 of the button rod 100, and in the guide seat 200, a guide groove 205 for inserting the sliding protrusion 125 is formed on the two inner surfaces of the insertion hole 210.

[0100] The guide groove 205 is used to guide the sliding motion of the sliding protrusion 125 when the sliding protrusion 125 of the sliding unit 120 is inserted therein. Just like the insertion hole 210 formed to be inclined downward in the forward direction of the sliding unit 120, the guide groove 205 may also be formed to be inclined downward in the forward direction of the sliding unit 120. Therefore, the guide groove 205 may be formed parallel to the inclined surface 211 of the insertion hole 210. The guide grooves 205 may be formed on both side surfaces inside the insertion hole 210, respectively.

[0101] In addition, a spring 206 may be disposed in an inner front portion of the guide groove 205 to elastically support the sliding protrusion 125 of the sliding unit 120 .

[0102] The spring 206 is used to elastically support the slide protrusion 125. As the slide unit 120 moves forward, the connector 41 of the sensing unit 40 is separated from the connector 51 of the inspection plate 50. Then, the slide unit 120 can return to its original position by the restoring force of the spring 206.

[0103] The sliding protrusions 125 can be set on both side surfaces of the sliding unit 120, and each sliding protrusion 125 can be inserted into the guide groove 205 inside the insertion hole 210 of the guide seat 200, so that as the sliding unit 120 moves, the sliding protrusion 125 can be guided and moved in the guide groove 205.

[0104] In the automatic separation jig 1000 according to the second aspect of the present disclosure, when the connector 41 of the sensing unit 40 and the connector 51 of the inspection plate 50 are separated, as the button lever 100 moves forward, the sliding unit 120 of the button lever 100 moves forward from the insertion hole 210 of the guide seat 200. At the same time, the sliding protrusion 125 inserted into the guide groove 205 moves forward in the guide groove 205.

[0105] Then, the sliding protrusion 125 moves along the downwardly inclined guide groove 205 so that the sliding unit 120 can move forward and gradually move downward. In addition, the sliding protrusion 125 can compress the spring 206 while moving forward in the guide groove 205.

[0106] As the sliding unit 120 gradually moves downward, the hook pressing unit 122 formed on the lower surface of the sliding unit 120 presses the hook 42 of the connector 41, thereby releasing the fixing of the connector 41 of the sensing unit 40 and the connector 51 of the inspection board 50. Then, as the sliding unit 120 moves forward, the sliding unit 120 pushes the connector 41 of the sensing unit 40 so that the connector of the sensing unit can be completely separated from the connector 51 of the inspection board 50.

[0107] Then, when the operator releases the pressing of the button unit 110 , the slide protrusion 125 returns to its original position by the restoring force of the compressed spring 206 , and this allows the button lever 100 to return to its original position.

[0108] In the automatic separation jig 1000 according to the second aspect of the present disclosure, the sliding protrusions 125 are provided on both side surfaces of the sliding unit 120 of the button lever 100, and the sliding protrusions 125 are inserted into the guide grooves 205 in the insertion hole 210 and moved. Thus, the sliding unit 120 is not twisted to the left or right, the linearity is improved, and the separation operation of the connector 41 can be performed more stably.

[0109] Although the present disclosure has been described above with reference to preferred aspects, the present disclosure is not limited to the aforementioned aspects. It will be understood by those skilled in the art that various modifications and changes can be made to the present disclosure without departing from the spirit of the present disclosure.
