Description

[Technical Field]

[0001] The present invention relates to an automatic separation jig for manufacturing a battery module, and more particularly to a jig that can automatically separate a connector of a sensing electrical component of a battery module from an inspection board with one touch during a battery module manufacturing process. [Background technology]

[0002] Secondary batteries are batteries that can be charged and discharged, unlike primary batteries that cannot be recharged, and are used not only in portable devices but also in electric vehicles (EVs) and hybrid electric vehicles (HEVs), which are powered by electrical sources.

[0003] Currently widely used types of secondary batteries include lithium ion batteries, lithium polymer batteries, nickel cadmium batteries, nickel metal hydride batteries, and nickel zinc batteries. The operating voltage of such unit secondary battery cells, i.e., unit battery cells, is approximately 2.5V to 4.6V. Therefore, when a higher output voltage is required, a battery pack is constructed by connecting multiple battery cells in series. In addition, a battery pack may be constructed by connecting multiple battery cells in parallel depending on the required charge / discharge capacity of the battery pack. Therefore, the number of battery cells included in the battery pack may be variously set depending on the required output voltage or charge / discharge capacity.

[0004] When configuring a battery pack by connecting a number of battery cells in series / parallel, a common method is to first configure a battery module consisting of at least one battery cell, preferably a number of battery cells, and then use at least one such battery module to configure the battery pack by adding other components. Here, a battery module refers to a component in which a number of battery cells are connected in series or parallel, and a battery pack refers to a component in which a number of battery modules are connected in series or parallel to increase capacity, output, etc.

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

[0006] FIG. 1 is a diagram showing a state in which a connector 41 of a sensing electrical component and an inspection board 50 are connected in a conventional battery module, and FIG. 2 is a diagram showing a state in which the connector 41 of the sensing electrical component and the inspection board 50 in FIG. 1 are separated.

[0007] As shown in the figure, in a conventional battery module, the connector 41 of the sensing electrical component is configured with a hook structure to prevent the connector from coming off due to vibration or impact in the field, or is configured with a device in which the connector 41 is press-fitted so that it cannot be easily released.

[0008] Therefore, on the production line, after the final EOL inspection of the product, it is difficult to disassemble the connector 41 of the sensing electrical component in the module from the connector 51 of the inspection board 50, which results in problems such as a narrow space between the inspection board 50 and the product connector 41, difficult connector disassembly work, and damage to physically weak electrical components. Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide an automatic separation jig for battery modules that can eliminate the source (fundamentally) of defects when disassembling connectors in an inspection process for battery module manufacturing, reduce production losses and costs by improving workability, and solve safety problems caused by damage to electrical components in high-voltage products. [Means for solving the problem]

[0010] An automatic separation jig for manufacturing a battery module according to the present invention includes a button lever and a guide holder to which the button lever is coupled and which guides movement of the button lever, and is characterized in that the automatic separation jig separates a connector of a battery module coupled to a connector of an inspection board by operation of the button lever.

[0011] A plurality of the button levers are spaced apart from one another and are disposed on the guide holder.

[0012] The button lever includes a button portion and a slide portion movably disposed on the guide holder.

[0013] The slide portion extends in one direction from one side of the button portion.

[0014] The slide portion is formed integrally with the button portion.

[0015] The slide portion also includes a connector pressing rib for pressing the connector of the battery module.

[0016] The slide portion also includes a hook pressing portion for pressing a hook of the connector of the battery module.

[0017] The guide holder also includes an insertion hole into which the slide portion is inserted to guide the movement of the slide portion.

[0018] A plurality of the button levers are spaced apart from one another and arranged on the guide holder, and the insertion holes are plural, with the slide portions being inserted into the insertion holes, respectively.

[0019] The insertion hole is formed from one side surface of the guide holder to the other side surface on the opposite side.

[0020] The insertion hole has a downwardly inclined surface at the bottom so that the slide portion moves downward while advancing during sliding movement.

[0021] The guide holder further includes an insertion groove on one side thereof in which the button portion is disposed.

[0022] The insertion groove is connected to one end of the insertion hole.

[0023] In addition, the automatic separation jig for manufacturing battery modules is disposed on the inspection board.

[0024] A lower groove is formed in the lower portion of the guide holder, and a connector of the testing board is positioned in the lower groove.

[0025] The connector of the battery module is preferably a connector of a sensing unit in the battery module. [Effects of the Invention]

[0026] Therefore, according to the present invention, when manufacturing a battery module, the connector can be disassembled in a one-touch manner even in a small space, and loss and risk due to damage to electrical components can be prevented.

[0027] Furthermore, according to the present invention, there is an advantage that the connector of the battery module can be separated from the connector of the inspection board in one operation. [Brief explanation of the drawings]

Conversely, when a part is described as being "under" another part, it means that there is no other part between them.

[0031] Before describing the automatic separation jig 1000 for manufacturing a battery module according to the present invention, the structure of the battery module 1 will be described with reference to FIGS.

[0032] The battery module 1 may include a number of battery cells 10, a module housing 20, and a number of busbars 30, and may further include a sensing unit 40 connected to the busbars 30 for sensing the voltage and temperature of each cell.

[0033] The battery cell 10 may be a cylindrical battery cell 10 in which an electrode assembly is incorporated into a metal can. The cylindrical battery cell 10 may include a battery can 11 made of a lightweight, conductive metal material such as aluminum in a cylindrical shape, a jelly-roll-like electrode assembly housed inside the battery can 11, and a top cap attached to the top of the battery can 11. The top cap may be connected to a positive electrode tab of the electrode assembly to function as a positive terminal, and the battery can 11 may be connected to a negative electrode tab of the electrode assembly to function as a negative terminal.

[0034] The cylindrical battery cells 10 may be inserted into the module housing 20, and the cylindrical battery cells 10 may be connected to each other in series and / or parallel by being wire-bonded to the bus bars 30 in a predetermined pattern.

[0035] The battery cells applied to the battery module 1 should not necessarily be limited to cylindrical battery cells 10, and for example, the battery module 1 according to the present invention can also be configured using can-type battery cells in which the shape of the battery can 11 is not cylindrical but is rectangular or has other shapes.

[0036] The module housing 20 is a structure for accommodating and fixing the battery cells 10 therein and protecting the battery cells 10 from external shocks and vibrations, and may be configured to include a cell bottom frame 22 and a cell top frame 21.

[0037] The cell bottom frame 22 has a rectangular box shape and is provided with cell insertion openings inside its outer frame, and is configured so that the battery cells 10 can be inserted into the cell insertion openings one by one. For example, as shown in FIG. 4 , the battery cells 10 may be inserted into each cell insertion opening with the top cap facing upward and its lower region, i.e., the bottom of the battery can 11, facing downward. Here, the cell insertion openings may be configured to penetrate the bottom surface of the cell bottom frame 22, and the bottom of the battery can 11 of the battery cell 10 may be exposed below the bottom surface of the cell bottom frame 22. Although not shown in the figure, an insulating thermally conductive pad may be attached to the bottom surface of the cell bottom frame 22, and a cooling plate or heat sink (containing a refrigerant inside) may be attached to the other surface of the thermally conductive pad to absorb heat from the cylindrical battery cells 10.

[0038] The cell bottom frame 22 may be firmly connected to the cell top frame 21 by hook fastening and long bolts (not shown).

[0039] The cell top frame 21 covers the upper region of the battery cell 10 and may be configured to be connectable to the cell bottom frame 22 .

[0040] For example, the cell top frame 21 may be provided with a cell socket (not shown) that matches the cell insertion opening of the cell bottom frame 22 vertically, and when the cell top frame 21 and the cell bottom frame 22 are combined, the battery cells 10 may be pulled into the cell socket from the top cap, and the upper areas of all the battery cells 10 may be configured to be covered by the cell top frame 21.

[0041] The cell top frame 21 may have a top surface that covers the top sides of all the battery cells 10 and four side surfaces that, together with the cell bottom frame 22, form a wall that surrounds the outside of all the battery cells 10. As shown in Fig. 5, the top surface of the cell top frame 21 includes a number of holes 21a and seating grooves 21b. Side plates 23 may be coupled to the side surfaces of the cell top frame 21.

[0042] The hole 21a is formed by partially perforating the cell top frame 21 so that the top end of the top cap or battery can 11 of the battery cell 10 can be partially exposed to the outside.

[0043] 4, the cell bottom frame 22 may be configured so that when the battery cells 10 are inserted, the battery cells 10 are arranged in multiple rows in the X-axis or Y-axis direction of the module housing 20. When the battery cells 10 are covered with the cell top frame 21, the top end of the top cap or battery can 11 of each battery cell 10 is exposed to the outside.

[0044] The holes 21a are used as passages that enable the battery cells 10 located inside the module housing 20 to be connected to the bus bar 30 located outside the module housing 20 by metal wires. For example, the bus bar 30 is connected to the upper end of the top cap or battery can 11 exposed through the holes 21a by metal wires. For example, a wire bonding method may be used in which one end of the metal wire is ultrasonically welded to the upper end of the top cap or battery can 11 and the other end of the metal wire is ultrasonically welded to the bus bar 30.

[0045] The seating grooves 21b are locations where the bus bars 30 are seated and fixed, and extend along the longitudinal direction (Y-axis direction) of the module housing 20, and are provided at predetermined intervals along the width direction (X-axis direction) of the module housing 20. A bus bar 30, which is a straight-shaped metal conductor with the same width on both sides, may be placed in each of the seating grooves 21b.

[0046] The bus bar 30 has a width substantially equal to that of the seating groove 21b, and is prevented from moving in the width direction (X-axis direction).

[0047] In addition, pin-shaped or column-shaped protrusions (in the Z-axis direction) may be provided on the surface of the seating groove 21b, and pinholes into which the pins of the seating groove 21b are inserted may be provided in the busbar 30. Therefore, the pins of the seating groove 21b are inserted into the pinholes of the busbar 30, thereby preventing the busbar 30 from moving.

[0048] In the battery module 1, the sensing unit 40 is an electrical component for sensing voltage, temperature, etc., and may include a sensing plate.

[0049] In order to inspect the product during the battery module manufacturing process, it is necessary to assemble the connector 41 of the sensing electrical component with the inspection board 50 equipped on the production line. The connector 41 of the sensing electrical component may be configured with a hook structure to prevent the connector 41 from coming off due to vibration or impact in the field, or may be configured with a device in which the connector 41 is press-fitted and is not easily released.

[0050] Therefore, on the production line, after the final EOL (End of Line) inspection of the product, it is difficult to disassemble the connector of the sensing electrical component from the module, which leads to problems such as the narrow space between the inspection board and the product connector, difficult connector disassembly work, and damage to the physically weak electrical component.

[0051] In order to solve these problems, the present invention provides an automatic separation jig 1000 for battery module manufacturing that solves problems that arise from the connector disconnection work that is necessarily required during EOL function inspection in the battery module manufacturing process.

Fig. 8 is a bottom perspective view of the button lever shown in Fig. 7. Fig. 9 is a view showing a state in which the automatic separation jig according to the present invention is mounted on an inspection board. Fig. 10 is a cross-sectional view showing a state in which the connector of the sensing unit is connected to the inspection board when the automatic separation jig according to the present invention is mounted on the inspection board. Fig. 11 is a cross-sectional view showing a state in which the connector of the sensing unit is separated from the inspection board by the automatic separation jig according to the present invention. Fig. 12 is a perspective view showing a state in which the separation of the connector of the sensing unit from the inspection board is completed.

[0053] An automatic separation jig 1000 for manufacturing a battery module according to an embodiment of the present invention includes a plurality of button levers 100 and a guide holder 200 to which the button levers 100 are coupled.

[0054] The button lever 100 is a one-touch button lever 100 for separating the connector 41 of the sensing unit 40 from the testing board 50 with a single touch, and may include a button portion 110 and a slide portion 120 .

[0055] The button unit 110 is used to move the slide unit 120 to release the coupling of the connector 41, and when a user presses the button unit 110 with a finger in the direction of the arrow as shown in Fig. 11, the slide unit 120 moves to release the coupling of the connector 41. The plurality of button units 110 may be respectively positioned in the insertion grooves 220 of the guide holder 200.

[0056] The slide portion 120 is used to disconnect the connector 41 from the inspection board 50 by operating the button portion 110, and is formed by extending forward from the lower part of the button portion 110 and is inserted into the insertion hole 210 of the guide holder 200. By operating the button portion 110, the slide portion 120 slides out of the insertion hole 210, thereby disconnecting the connector 41.

[0057] The slide portion 120 may include a connector pushing rib 121 and a hook pushing portion 122 .

[0058] As shown in FIG. 8, the connector pressing ribs 121 are formed to protrude downward from both sides of the lower surface of the sliding part 120 and extend in the longitudinal direction, and can play a role in pressing the connector 41 when the sliding part 120 slides within the insertion hole 210 of the guide holder 200.

[0059] 8, the hook pressing part 122 protrudes downward from the front of the lower surface of the sliding part 120 and serves to press the hook 42 of the connector 41 when the sliding part 120 slides in the insertion hole 210 of the guide holder 200. The sliding part 120 may be formed integrally with the button part 110.

[0060] The material of the button lever 100 may be synthetic resin in this embodiment, or may be other materials.

[0061] In this embodiment, four button levers 100 are shown coupled to the guide holder 200, but the number of button levers 100 may be changed.

[0062] The guide holder 200 is coupled to the button lever 100 to guide the movement of the button lever 100 in response to the operation of the button portion 110, and may include an insertion hole 210 into which the slide portion 120 of the button lever 100 is inserted, and an insertion groove 220 in which the button portion 110 of the button lever 100 is positioned.

[0063] The insertion holes 210 of the guide holder 200 are where the slide portions 120 of the button levers 100 are inserted, and four insertion holes 210, the same number as the number of button levers 100, may be formed spaced apart from each other in the longitudinal direction of the guide holder 200.

[0064] As shown in the figure, the insertion hole 210 is formed through the guide holder 200 from one side to the other, and the slide portion 120 of the button lever 100 is inserted into one end of the insertion hole 210 so that the end of the slide portion 120 protrudes from the other end of the insertion hole 210.

[0065] The slide portion 120 of the button lever 100 is seated at the bottom of the insertion hole 210, and the insertion hole 210 that guides the movement of the slide portion 120 may be formed to be inclined downward in the forward direction of the slide portion 120 relative to the bottom of the guide holder 200, and the bottom of the insertion hole 210 may have an inclined surface 211.

[0066] Therefore, when the button lever 100 moves forward within the insertion hole 210, as shown in Figures 10 and 11, the slide portion 120 moves along the downwardly inclined inclined surface 211, and the slide portion 120 can also move gradually downward while moving forward.

[0067] The insertion grooves 220 of the guide holder 200 are inserted into the buttons 110 of the button lever 100, and four insertion grooves 220, the same as the number of button levers 100, are formed in the longitudinal direction of the guide holder 200 at intervals.

[0068] As shown in the figure, the insertion groove 220 is recessed inward from one side of the guide holder 200 , and the insertion groove 220 communicates with one end of the insertion hole 210 .

[0069] Therefore, the slide portion 120 of the button lever 100 is inserted into the insertion hole 210 , and the button portion 110 can be positioned within the insertion groove 220 .

[0070] In addition, the guide holder 200 may have fastening holes 201. As shown in the figure, the fastening holes 201 are formed to penetrate the guide holder 200 from above to below, and are for fixing the guide holder 200 with fixing bolts (not shown). The fixing bolts are inserted into the fastening holes 201, and the inserted fixing bolts are fastened to the inspection board 50, so that the automatic separation jig 1000 can be fixed to the inspection board 50.

[0071] Next, an operation method of the automatic separation jig 1000 for manufacturing battery modules according to the present invention having the above-described configuration will be described.

[0072] First, the automatic separation jig 1000 for manufacturing a battery module according to the present invention is placed on the inspection board 50 of the production line equipment. Specifically, as shown in Fig. 9, the automatic separation jig 1000 is placed on the inspection board 50 so that the connector 51 of the inspection board 50 is positioned in the lower groove 230 formed in the lower part of the automatic separation jig 1000, and the fixing bolts inserted into the fixing holes 201 can be fastened to the inspection board 50 to fix the automatic separation jig 1000 to the inspection board 50.

[0073] Then, in order to test the battery module 1, the connector 41 of the sensing unit 40 can be coupled to the connector 51 of the testing board 50 in the battery module 1. Specifically, the hook 42 of the connector 41 in the sensing unit 40 is caught and fixed in the connector 51 of the testing board 50. At the same time, as shown in FIG. 10 , when the connector 41 of the sensing unit 40 is inserted into the connector 51 of the testing board 50, the connector 41 of the sensing unit 40 presses the button lever 100, causing the button lever 100 to be positioned at a fixed position.

[0074] In this way, with the connector 41 of the sensing unit 40 connected to the connector 51 of the testing board 50, after the final testing is completed, each connector 41 of the sensing unit 40 can be separated from the connector 51 of the testing board 50.

[0075] When separating the connector 41 of the sensing unit 40 from the connector 51 of the inspection board 50, an operator can press the button portion 110 of the button lever 100 in the automatic separation jig 1000 with his / her finger in the direction of the arrow shown in FIG.

[0076] This causes the button lever 100 to move forward, and the slide portion 120 of the button lever 100 is guided forward by the insertion hole 210 of the guide holder 200, moving along the downwardly inclined inclined surface 211 that forms the bottom of the insertion hole 210, allowing the slide portion 120 to gradually move downward as it moves forward.

[0077] As the sliding part 120 moves gradually downward, the hook pressing part 122 formed on the underside of the sliding part 120 presses the hook 42 of the connector 41, thereby releasing the connection between the connector 41 of the sensing part 40 and the connector 51 of the testing board 50. Next, as the sliding part 120 moves forward, the sliding part 120 presses the connector 41 of the sensing part 40, so that the connector 41 of the sensing part 40 can be completely separated from the connector 51 of the testing board 50.

[0078] FIG. 12 is a diagram showing a state in which the connector of the sensing unit is completely separated from the testing board.

[0079] Therefore, in the present invention, as described above, when an operator presses the button part 110 in a one-touch manner, the slide part 120 of the button lever 100 presses the hook 42 of the connector 41, and the connector 41 is separated from the inspection board 50. This eliminates the source (fundamental) of the cause of defects when disassembling the connector in the inspection process for manufacturing the battery module, solves safety issues caused by damage to electrical components, and reduces production loss and costs through improved workability.

[0080] Next, an automatic separation jig according to a second embodiment of the present invention will be described. Fig. 13 is a perspective view of the automatic separation jig according to the second embodiment of the present invention. Fig. 14 is a perspective view of the button lever in Fig. 13. Fig. 15 is a cross-sectional view showing a state in which the automatic separation jig shown in Fig. 13 is seated on an inspection board and the connector of the sensing unit is connected to the inspection board.

[0081] The automatic separation jig 1000 according to the second embodiment of the present invention differs from the first embodiment in that slide protrusions 125 are arranged on both sides of the slide portion 120 of the button lever 100, and in the guide holder 200, guide grooves 205 into which the slide protrusions 125 are inserted are formed on both sides of the interior of the insertion hole 210.

[0082] The guide groove 205 is for receiving the slide protrusion 125 of the slide portion 120 and guiding the sliding movement of the slide protrusion 125, and like the insertion hole 210 formed with a downward inclination in the forward movement direction of the slide portion 120, the guide groove 205 is also formed with a downward inclination in the forward movement direction of the slide portion 120. Therefore, the guide groove 205 is formed parallel to the inclined surface 211 of the insertion hole 210. The guide groove 205 may be formed on both side surfaces inside the insertion hole 210.

[0083] Furthermore, a spring 206 for elastically supporting the slide protrusion 125 of the slide portion 120 may be arranged in the inner front portion of the guide groove 205 .

[0084] The spring 206 is for elastically supporting the slide protrusion 125, and after the connector 41 of the sensing unit 40 is separated from the connector 51 of the inspection board 50 as the slide unit 120 moves forward, the restoring force of the spring 206 can return the slide unit 120 to its original position.

[0085] The slide protrusions 125 are arranged on both sides of the slide portion 120, and each slide protrusion 125 is inserted into the internal guide groove 205 of the insertion hole 210 of the guide holder 200, so that the slide protrusions 125 can be guided by the guide groove 205 and moved in accordance with the movement of the slide portion 120.

[0086] In the automatic separation jig 1000 according to the second embodiment of the present invention, when the connector 41 of the sensing unit 40 and the connector 51 of the inspection board 50 are separated, the button lever 100 moves forward and the slide portion 120 of the button lever 100 moves forward from the insertion hole 210 of the guide holder 200, and at the same time, the slide protrusion 125 inserted into the guide groove 205 moves forward within the guide groove 205.

[0087] As a result, the slide protrusion 125 moves along the downwardly inclined guide groove 206, and the slide part 120 moves forward and gradually moves downward. In addition, as the slide protrusion 125 moves forward within the guide groove 206, the spring 206 can be compressed.

[0088] As the sliding part 120 moves gradually downward, the hook pressing part 122 formed on the underside of the sliding part 120 presses the hook 42 of the connector 41, thereby releasing the connection between the connector 41 of the sensing part 40 and the connector 51 of the testing board 50. Next, as the sliding part 120 moves forward, the sliding part 120 presses the connector 41 of the sensing part 40, so that the connector 41 of the sensing part 40 can be completely separated from the connector 51 of the testing board 50.

[0089] Next, when the operator releases the pressure on the button portion 110, the restoring force of the compressed spring 206 causes the slide protrusion 125 to return to its original position, thereby allowing the button lever 100 to return to its original position.

[0090] In the automatic separation jig 1000 according to the second embodiment of the present invention, slide protrusions 125 are arranged on both sides of the slide portion 120 of the button lever 100, and the slide protrusions 125 are inserted into the guide grooves 205 in the insertion hole 210 and move, thereby improving the straightness of the slide portion 120 without twisting left and right, and enabling the separation operation of the connector 41 to be performed more stably.

[0091] As has been seen from the above, the present invention has been described with reference to preferred embodiments, but is not limited to the above embodiments, and various changes and modifications may be made by a person having ordinary skill in the art to which the invention pertains, without departing from the technical spirit of the present invention. [Industrial Applicability]

[0092] The present invention provides a jig that can automatically disconnect a connector of a sensing electrical component of a battery module from an inspection board with a single touch during the battery module manufacturing process.
