  The present invention relates to a non-bipolar battery manufacturing method and a non-bipolar battery manufacturing apparatus.

  In recent years, in order to cope with global warming, reduction of carbon dioxide emissions has been strongly desired. In the automobile industry, there is high expectation for the reduction of carbon dioxide emissions by introducing electric vehicles and hybrid electric vehicles, and the development of electrochemical devices such as motor-driven batteries that hold the key to commercialization of these devices is actively underway. ing. As a battery for driving a motor, a lithium ion battery having a relatively high theoretical energy is attracting attention, and is currently being developed rapidly.

  The first forming unit 210 forms the first continuous body 212 in which the negative electrode 20 is held on the first separator base material 211 having an elongated shape along the direction in which the first separator base material 211 extends. To do. The first separator substrate 211 is wound around a first separator roll 214. The tip of the first separator base material 211 fed out from the first separator roll 214 is fixed to the stacking jig 201. By rotating the stacking jig 201, the first separator base material 211 is sequentially fed out from the first separator roll 214 and conveyed. The first separator substrate 211 is transported via the first suction roller 215 and the plurality of guide rollers 216. The first tension applying unit 213 includes a first brake 213 that is connected to the rotation shaft of the first separator roll 214 and applies a braking force in a direction to stop the rotation of the first separator roll 214. This is because an appropriate tension is applied to the first separator substrate 211 to be conveyed so that no slack is generated.

  The first forming part 210 includes a first cutout part 220 that cuts out the negative electrode 20 from the first electrode substrate 221 having a long shape. The first electrode base material 221 for the negative electrode 20 is wound around the first electrode roll 222. The first electrode base material 221 is fed out from the first electrode roll 222 and supplied to the first cutout unit 220 via the plurality of guide rollers 223. As shown in FIGS. 7A, 7 </ b> B, and 7 </ b> C, the first cutout unit 220 includes a first conveyance belt 224 that sucks and conveys the first electrode base material 221 and a first conveyance belt 224. A first cutting member 225 for cutting the first electrode substrate 221 above, a first transfer unit 226 for transferring the cut-out negative electrode 20 from the first transport belt 224 to the first separator substrate 211, It has. The first conveying belt 224 is configured by an endless suction belt, and is stretched between the driving roller 224a and the driven roller 224b. The 1st cutting member 225 comprises a laser cutter. The suction belt is a stainless steel belt, and is formed with an adsorption hole 224c that adsorbs the first electrode base 221 and the cut-out negative electrode 20, and a slit 224d that transmits laser. A suction unit 227 is disposed inside the first conveyance belt 224, and the suction unit 227 is connected to the vacuum pump 228. The first electrode substrate 221 is adsorbed and conveyed by the first conveyor belt 224, and the first electrode substrate 221 is cut by a laser cutter. In the cutting part, the laser passes through the slit 224 d of the first transport belt 224. Air is also sucked from the slit 224d, and the sputter is sucked and captured by the suction portion 227 together with this air. Since the assist gas at the time of cutting is also sucked from the slit 224d, the assist gas concentrates on the cutting portion. For this reason, spatter is reduced and generation of burrs can be suppressed. The end material 221 a after the negative electrode 20 is cut out from the first electrode base material 221 is collected in the collection box 229.

  A first rotary table 281 that rotates the negative electrode 20 cut out from the first electrode base material 221 by 90 degrees is disposed downstream of the first cutting member 225 in the moving direction of the first conveying belt 224. . The cut-out negative electrode 20 is once adsorbed from the first conveying belt 224 to the first rotary table 281 and rotated 90 degrees and then adsorbed again to the first conveying belt 224. FIG. 8A shows the orientation of the negative electrode 20 when cut out, and FIG. 8B shows the orientation of the negative electrode 20 after being rotated 90 degrees. The movement of the negative electrode 20 between the first conveyor belt 224 and the first rotary table 281 is caused by the suction force of the first conveyor belt 224 at the position facing the first rotary table 281 and the first rotation. This is done by controlling the strength with the suction force of the table 281. An application unit 282 for applying an adhesive 285 for temporarily fixing the negative electrode 20 and the first separator substrate 211 to the negative electrode 20 is provided downstream of the first rotary table 281 in the moving direction of the first conveying belt 224.

The The movement drive is performed via an actuator, a link mechanism or the like (not shown). By moving the driving roller 224a to the transfer position, the first transport belt 224 comes into contact with the first suction roller 215 via the first separator substrate 211, and the first transfer unit 226 is configured. In the first transfer unit 226, the cut-out negative electrode 20 is transferred from the first transport belt 224 to the first separator substrate 211. In the first transfer unit 226, the direction in which the first separator base material 211 is transported is the same as the direction in which the negative electrode 20 is transported, so the first separator base material 211 is transported from the first transport belt 224. The negative electrode 20 can be smoothly transferred to the substrate.

  Note that the negative electrode 20 may be held on the first separator substrate 211 by an adsorption method instead of the application of the adhesive 285.

  The second forming unit 230 forms a second continuous body 232 in which the positive electrode 40 is held side by side along the direction in which the second separator substrate 231 extends on the second separator substrate 231 having a long shape. To do. The second separator substrate 231 is wound around the second separator roll 234. The tip of the second separator substrate 231 fed out from the second separator roll 234 is fixed to the stacking jig 201. By rotating the stacking jig 201, the second separator base material 231 is sequentially fed from the second separator roll 234 and conveyed. The second separator base 231 is conveyed via the second suction roller 235 and the plurality of guide rollers 236. The second tension applying unit 233 includes a second brake 233 that is connected to the rotation shaft of the second separator roll 234 and applies a braking force in a direction to stop the rotation of the second separator roll 234. This is because an appropriate tension is applied to the second separator base material 231 to be conveyed so that no looseness occurs.

  The 2nd formation part 230 contains the 2nd cut-out part 240 which cuts out the positive electrode 40 from the 2nd electrode base material 241 which has a long shape. The second electrode substrate 241 for the positive electrode 40 is wound around the second electrode roll 242. The second electrode substrate 241 is fed out from the second electrode roll 242 and supplied to the second cutout part 240 via the plurality of guide rollers 243. The second cutout unit 240 is configured in the same manner as the first cutout unit 220, and the second conveyance belt 244 that sucks and conveys the second electrode base material 241 and the second conveyance belt 244 on the second conveyance belt 244. A second cutting member 245 for cutting the electrode base material 241 and a second transfer unit 246 for transferring the cut positive electrode 40 from the second transport belt 244 to the second separator base material 231 are provided. The second conveying belt 244 is configured by an endless suction belt, and is stretched between the driving roller 244a and the driven roller 244b. The 2nd cutting member 245 comprises a laser cutter. The suction belt is a stainless steel belt, and is formed with an adsorption hole for adsorbing the second electrode substrate 241 and the cut out positive electrode 40, and a slit through which a laser is transmitted. A suction unit 247 is disposed inside the second transport belt 244, and the suction unit 247 is connected to the vacuum pump 248. The second electrode substrate 241 is adsorbed and conveyed by the second conveyance belt 244, and the second electrode substrate 241 is cut by a laser cutter. In the cutting part, the laser passes through the slit of the second conveyor belt 244. Air is also sucked from the slit, and the sputter is sucked and captured by the sucking portion 247 together with the air. Since assist gas at the time of cutting is also sucked from the slit, the assist gas concentrates on the cutting portion. For this reason, spatter is reduced and generation of burrs can be suppressed. The end material after cutting out the positive electrode 40 from the second electrode substrate 241 is collected in a collection box 249.

  A second rotary table 283 that rotates the positive electrode 40 cut out from the second electrode base material 241 by 90 degrees is disposed downstream of the second cutting member 245 in the moving direction of the second transport belt 244. . The cut out positive electrode 40 is once adsorbed from the second conveyance belt 244 to the second rotary table 283, rotated 90 degrees, and again adsorbed to the second conveyance belt 244. The movement of the positive electrode 40 between the second conveyor belt 244 and the second rotary table 283 is caused by the suction force of the second conveyor belt 244 at the position facing the second rotary table 283 and the second rotation. This is done by controlling the strength of the suction force of the table 283. An application unit 274 that applies an adhesive 285 for temporarily fixing the positive electrode 40 and the second separator substrate 231 to the positive electrode 40 is provided downstream of the second rotary table 283 in the moving direction of the second conveying belt 244. Is arranged. The adhesive 285 is applied to the four corners of the positive electrode 40. The driving roller 244a is driven to move between a transfer position where the second conveyor belt 244 is brought into contact with the second suction roller 235 and a retracted position where the second conveyor belt 244 is separated from the second suction roller 235. The The movement drive is performed via an actuator, a link mechanism or the like (not shown). By moving the driving roller 244a to the transfer position, the second transport belt 244 comes into contact with the second suction roller 235 via the second separator base material 231, and the second transfer unit 246 is configured. In the second transfer unit 246, the cut out positive electrode 40 is transferred from the second transport belt 244 to the second separator base 231. In the second transfer unit 246, the direction in which the second separator base 231 is transported and the direction in which the positive electrode 40 is transported are the same, and therefore, the second separator base 231 is transported from the second transport belt 244. The positive electrode 40 can be transferred smoothly.

  Note that the positive electrode 40 may be held on the second separator substrate 231 by an adsorption method instead of the application of the adhesive 285.

  The stacking jig 201 has a polygonal column shape and has a plurality of support surfaces 202a to 202d. The illustrated stacking jig 201 has a quadrangular prism shape with a square cross section, and includes four support surfaces 202a to 202d. The stacking jig 201 has a drive unit 203 connected to the rotating shaft 204. The drive unit 203 includes a motor M, a gear train, and the like. By rotating the stacking jig 201 by a unit angle by the drive unit 203, the first continuous body 212 and the second continuous body 232 are overlapped and wound around the stacking jig 201, and are respectively wound around the support surfaces 202a to 202d. The sub assembly unit 51 is laminated. Since the illustrated stacking jig 201 has four support surfaces 202a to 202d, the unit angle is 90 degrees.

  The 1st separator base material 211 and the 2nd separator base material 231 have air permeability. The stacking jig 201 includes a suction member 205 that sucks the first separator base material 211 and the second separator base material 231 between the adjacent support surfaces 202a to 202d. Between the adjacent support surfaces 202a to 202d, an adsorbent for adsorbing the first separator substrate 211 and the second separator substrate 231 is formed. A suction unit 206 is disposed inside the stacking jig 201, and the suction unit 206 is connected to a vacuum pump 207. The suction member 205 includes the suction holes, the suction unit 206, the vacuum pump 207, and the like. The first separator base material 211 between the negative electrodes 20 and the exposed part of the second separator base material 231 between the positive electrodes 40 are sucked and adsorbed to the laminating jig 201, whereby the first separator The base material 211 and the second separator base material 231 are pressed toward the stacking jig 201. Thereby, it is suppressed that wrinkles generate | occur | produce in the negative electrode 20 and the positive electrode 40 at the time of lamination | stacking.

  The stacking jig 201 wraps the first continuous body 212 and the second continuous body 232 in an overlapping manner until, for example, six layers of the subassembly unit 51 are stacked on each of the support surfaces 202a to 202d. By winding the first continuum 212 and the second continuum 232 around the stacking jig 201, only the first separator base 211 and the second separator base 231 are near the corners of the stacking jig 201. Are stacked.

  The separation unit 250 includes, for example, a separator cutting blade 251 that cuts the first separator base material 211 and the second separator base material 231 that connect the adjacent subassembly units 51 stacked on the adjacent support surfaces 202a to 202d. Have. By cutting the first separator substrate 211 and the second separator substrate 231, the assembly unit 50 stacked on each of the four support surfaces 202 a to 202 d is separated for each of the support surfaces 202 a to 202 d. Thereby, four assembly units 50 formed by laminating a plurality of sub assembly units 51 can be obtained simultaneously.

  The control unit 260 is configured mainly with a CPU and a memory, and controls the operations of the first forming unit 210, the second forming unit 230, the driving unit 203, and the separating unit 250.

  In the first forming unit 210, the control unit 260 has a first timing for holding the negative electrode 20 on the first separator base material 211. The timing is set such that the material 211 is fed and stacked on the next support surfaces 202a to 202d (for example, 202a). In the second forming unit 230, the control unit 260 has a second timing for holding the positive electrode 40 on the second separator base material 231, and the positive electrode 40 holding the second separator base 201 is rotated by the rotation of the stacking jig 201. The timing is set such that the material 231 is fed and stacked on the next support surfaces 202a to 202d (for example, 202a). The feed amount of the first separator base material 211 and the second separator base material 231 increases as the number of stacked sub assembly units 51 increases, but the control unit 260 controls each of the first timing and the second timing. Are kept the same.

  Referring to FIG. 9, the carriage 200 includes a movable base 271, a support post 272 that is provided on the base 271 and rotatably supports a rotating shaft 204 inserted through the stacking jig 201, and a rotating shaft 204. It has a clamp part 273 that is provided coaxially and clamps the assembly unit 50 on the stacking jig 201, and a drive part 203 that is provided on the base 271 and connected to the rotating shaft 204. The drive unit 203 includes a motor M, a gear train, and the like. The clamp part 273 includes a clamp piece 274 that is slidable on the support surfaces 202a to 202d of the stacking jig 201, and a position between the clamp piece 274 that faces the support surfaces 202a to 202d and a position that does not interfere with the stacking jig 201. And an advancing / retreating cylinder 275 for moving forward and backward, and a lifting / lowering cylinder 276 for lifting and lowering the clamp piece 274 along the radial direction. The advancing / retreating cylinder 275 is composed of, for example, a rodless cylinder, and the ascending / descending cylinder 276 is composed of a guided cylinder. A pallet 301 on which one negative electrode 20 is placed in the preparation unit 102 and a finger unit 302 used to move the assembly unit 50 on the lamination jig 201 to the pallet 301 are freely movable below the lamination jig 201. Is provided. As shown in FIG. 11A, the clamp piece 274 is formed with a passage portion 274a that allows the finger portion 302 to move. As shown in FIG. 11C, the pallet 301 is formed with a passage portion 301a that allows the finger portion 302 to move.

  A procedure for taking out the assembly unit 50 from the stacking jig 201 will be described. The assembly unit 50 is removed by moving the carriage 200 to the removal position P1 (see FIG. 4). The position of the rotating shaft 204 is determined, and the pallet 301 and the finger part 302 are moved to a position below the stacking jig 201 (see FIG. 9). The advancing / retreating cylinder 275 and the clamp piece 274 are raised radially outward by the elevating cylinder 276. The clamp piece 274 is advanced to a position facing the support surfaces 202a to 202d by the advance / retreat cylinder 275, and the advance / retreat cylinder 275 and the clamp piece 274 are lowered inward in the radial direction by the elevating cylinder 276 (FIG. 10A). See). Thereby, each assembly unit 50 on the four support surfaces 202a to 202d in the stacking jig 201 is clamped. The first separator base material 211 and the second separator base material 231 are cut by the separation unit 250, and the assembly unit 50 is separated for each of the support surfaces 202a to 202d. In a state where the assembly unit 50 is pressed by the clamp piece 274, the finger portion 302 is raised toward the assembly unit 50 (see FIG. 11A). After the assembly unit 50 is moved to the finger portion 302, the advance / retreat cylinder 275 and the clamp piece 274 are raised radially outward by the lifting cylinder 276, and the clamp piece 274 is attached to the stacking jig 201 by the advance / retreat cylinder 275. Retreat to a position where there is no interference (see FIGS. 10B and 11B). Then, after the assembly unit 50 is moved to the pallet 301, the finger portion 302 is retracted to a position where it does not interfere with the pallet 301 (see FIG. 11C). When the removal of one assembly unit 50 is completed, the rotating shaft 204 is rotated 90 degrees, the remaining assembly unit 50 is positioned downward, and the above-described extraction operation is repeated.

  Referring to FIG. 12, the preparation unit 102 includes a third cutout unit 310 that cuts out the negative electrode 20 from the electrode substrate of the negative electrode 20 having a long shape. The electrode base 311 of the negative electrode 20 is wound around the third electrode roll 312. The electrode base material 311 of the negative electrode 20 is fed out from the third electrode roll 312 and supplied to the third cutout part 310. The third cutout unit 310 includes a third conveyance belt 314 that sucks and conveys the electrode base material 311 of the negative electrode 20, and a third cutting member that cuts the electrode base material 311 of the negative electrode 20 on the third conveyance belt 314. 315, and a suction conveyance unit 316 that sucks and conveys the cut-out negative electrode 20 from the third conveyance belt 314 onto the pallet 301. The third conveyor belt 314 is composed of an endless suction belt, and is stretched between the driving roller 314a and the driven roller 314b. The third cutting member 315 is composed of a laser cutter. The suction belt is a stainless steel belt, and is formed with an adsorption hole for adsorbing the third electrode substrate and the cut-out negative electrode 20, and a slit through which a laser is transmitted. A suction unit 317 is disposed inside the third transport belt 314, and the suction unit 317 is connected to the vacuum pump 318. The electrode substrate 311 of the negative electrode 20 is adsorbed and conveyed by the third conveyance belt 314, and the electrode substrate 311 of the negative electrode 20 is cut by a laser cutter. In the cutting part, the laser passes through the slit of the third conveyor belt 314. Air is also sucked from the slit, and the sputter is sucked and captured by the suction portion 317 together with the air. Since assist gas at the time of cutting is also sucked from the slit, the assist gas concentrates on the cutting portion. For this reason, spatter is reduced and generation of burrs can be suppressed. The end material 311 a after the negative electrode 20 is cut out from the electrode base material 311 of the negative electrode 20 is collected in a collection box 319. The suction conveyance unit 316 has a suction pad 316 a provided so as to be movable between the third conveyance belt 314 and the pallet 301. The cut-out negative electrode 20 is lifted from the third transport belt 314 by the suction pad 316a and transported onto the pallet 301.

  Next, a method for manufacturing the non-bipolar battery 10 will be described.

  First, the first continuous body 212 is formed in which the negative electrode 20 is held on the first separator base material 211 having an elongated shape along the direction in which the first separator base material 211 extends.

  In the step of forming the first continuous body 212, the negative electrode 20 is cut out from the first electrode substrate 221 having a long shape. In this step, the first electrode base material 221 is cut on the first transport belt 224 that sucks and transports the first electrode base material 221, and the cut-out negative electrode 20 is transferred from the first transport belt 224 to the first transport belt 224. The separator substrate 211 is transferred.

  In the step of forming the first continuous body 212, the control unit 260 performs the first timing for holding the negative electrode 20 on the first separator base material 211. The timing is set such that one separator substrate 211 is fed and stacked on the next support surfaces 202a to 202d (for example, 202a).

  A second continuous body 232 in which the positive electrode 40 is held side by side along the direction in which the second separator base material 231 extends is formed on the second separator base material 231 having a long shape.

  In the step of forming the second continuous body 232, the positive electrode 40 is cut out from the second electrode substrate 241 having a long shape. In this step, the second electrode base material 241 is cut on the second transport belt 244 that sucks and transports the second electrode base material 241, and the cut out positive electrode 40 is transferred from the second transport belt 244 to the second transport belt 244. To the separator substrate 231.

  In the step of forming the second continuous body 232, the control unit 260 performs the second timing for holding the positive electrode 40 on the second separator base material 231. The timing is set such that the second separator base material 231 is fed and stacked on the next support surfaces 202a to 202d (for example, 202a).

  Next, the first continuous body 212 and the second continuous body 232 are wound around each other on the rotatable stacking jig 201 on which the plurality of support surfaces 202a to 202d are formed, so that the support surfaces 202a to 202d are wound. A plurality of sub-assembly units 51 are stacked on each. In this step, the first continuous body 212 and the second continuous body 232 are wound around the stacking jig 201 while applying tension to the first separator base material 211 and the second separator base material 231. By applying appropriate tension to the first separator base material 211 and the second separator base material 231 to be conveyed, the first separator base material 211 and the second separator base material 231 are prevented from being loosened. Can be transported and stacked.

  Further, the first continuum 212 and the second continuum 232 are attached to the stacking jig 201 while sucking the first separator base material 211 and the second separator base material 231 between the adjacent support surfaces 202a to 202d. Wrap around. The first separator base material 211 between the negative electrodes 20 and the exposed part of the second separator base material 231 between the positive electrodes 40 are sucked and adsorbed to the laminating jig 201, whereby the first separator The base material 211 and the second separator base material 231 are pressed toward the stacking jig 201. Thereby, it can suppress that a wrinkle generate | occur | produces in the negative electrode 20 and the positive electrode 40 at the time of lamination | stacking.

  The feed amount of the first separator base material 211 and the second separator base material 231 increases as the number of subassembly units 51 stacked increases. The controller 260 sends the first separator base material 211 and the second separator base material 231 by the rotation of the stacking jig 201, and the negative electrode 20 and the positive electrode 40 are stacked on the next support surfaces 202a to 202d. The timing (first timing and second timing) is maintained. For this reason, even if the feed amounts of the first separator base material 211 and the second separator base material 231 increase as the number of sub-assy units 51 stacked increases, the negative electrode 20 and the positive electrode 40 may be misaligned. Absent.

  When the predetermined number of sub-assembly units 51 are stacked, the first separator base material 211 and the second separator base material 231 are cut, and the carriage is moved to the take-out position P1 (see FIG. 4) where the assembly unit 50 is taken out. Move 200. The assembly units 50 on the four support surfaces 202a to 202d in the stacking jig 201 are clamped by the clamp portions 273 provided on the carriage 200 (see FIG. 10A).

  Next, the separation unit 250 cuts the first separator base material 211 and the second separator base material 231 that connect the adjacent sub-assembly units 51 stacked on the adjacent support surfaces 202a to 202d, and the assembly unit 50 is separated for each of the support surfaces 202a to 202d. Thereby, the assembly unit 50 formed by laminating a plurality of sub assembly units 51 can be obtained simultaneously with the number of support surfaces 202a to 202d (four in the illustrated example).

  In the preparation unit 102, the negative electrode 20 is cut out and placed on the pallet 301. The assembly unit 50 is taken out from the stacking jig 201 one by one, and the assembly unit 50 is moved onto the pallet 301 and carried out at the carry-out unit 103. Thereby, the formation of the power generation element 11 in which the negative electrode 20 is positioned in both outermost layers is completed.

  Thereafter, the production of the non-bipolar battery 10 is completed through a known process such as a step of bonding a tab to the power generation element 11 and a sealing of the power generation element 11 with the laminate sheet 12.

  As described above, the manufacturing method according to the present embodiment includes the step of forming the first continuous body 212, the step of forming the second continuous body 232, the first continuous body 212, and the second continuous body. A step of laminating a plurality of sub assembly units 51 on each of the support surfaces 202a to 202d of the stacking jig 201 by winding the body 232 while overlapping them, and a separation step of separating the assembly unit 50 for each of the support surfaces 202a to 202d. In addition, the manufacturing apparatus 100 according to the present embodiment embodies the above manufacturing method.

  According to the present embodiment, in manufacturing the non-bipolar battery 10 in which the separator 30 needs to be interposed between the positive electrode 40 and the negative electrode 20, the arrangement order of the electrodes becomes complicated, Without being restricted by the number of the support surfaces 202a to 202d, it becomes possible to improve productivity when manufacturing the non-bipolar battery 10.

  Further, the first separator base material 211 and the second separator base material 231 are sent by the rotation of the stacking jig 201 and the negative electrode 20 and the positive electrode 40 are stacked on the next support surfaces 202a to 202d (first 1 timing and second timing). For this reason, even if the feed amounts of the first separator base material 211 and the second separator base material 231 increase as the number of sub-assy units 51 stacked increases, the negative electrode 20 and the positive electrode 40 may be misaligned. Absent. There is no need to provide a mechanism for changing the pitch at which the negative electrode 20 and the positive electrode 40 are arranged so as to match the increase in the feed amount of the first separator substrate 211 and the second separator substrate 231, and the structure of the manufacturing apparatus 100 Simplification and reduction of equipment costs can be achieved.

  Further, since the first continuous body 212 and the second continuous body 232 are wound around the stacking jig 201 while applying tension to the first separator base material 211 and the second separator base material 231, no slack is generated. Thus, the first separator base material 211 and the second separator base material 231 can be conveyed and stacked.

  Further, the first continuum 212 and the second continuum 232 are attached to the stacking jig 201 while sucking the first separator base material 211 and the second separator base material 231 between the adjacent support surfaces 202a to 202d. It is wrapped around. The first separator base material 211 between the negative electrodes 20 and the exposed part of the second separator base material 231 between the positive electrodes 40 are sucked and adsorbed to the laminating jig 201, whereby the first separator The base material 211 and the second separator base material 231 are pressed toward the stacking jig 201. Thereby, it can suppress that a wrinkle generate | occur | produces in the negative electrode 20 and the positive electrode 40 at the time of lamination | stacking.

  In forming the first continuous body 212, the electrode base material 221 of the negative electrode 20 is cut on the first transport belt 224 that sucks and transports the electrode base material 221 of the negative electrode 20, and the cut negative electrode 20 One transfer belt 224 is transferred to the first separator substrate 211. In forming the second continuous body 232, the electrode base material 241 of the positive electrode 40 is cut on the second transport belt 244 that sucks and transports the electrode base material 241 of the positive electrode 40, and the cut positive electrode 40 is replaced with Second transfer belt 244 is transferred to second separator substrate 231. Since it is based on the transfer method, it is possible to transfer the electrodes at a higher speed than in the case where the electrodes are arranged side by side by the suction method, and the productivity when manufacturing the non-bipolar battery 10 can be further increased.

(Modification example of the layout of the manufacturing apparatus 100)
FIGS. 13A and 13B are diagrams illustrating a main part of a modified example of the layout of the manufacturing apparatus 100. FIG.

  As shown in FIG. 13A, the assembly unit 50 may be manufactured by providing two layers of the stacked portions 101 and the like, respectively. Further, as shown in FIG. 13B, a configuration may be adopted in which two rows of stacked portions 101 and the like are provided and the taken out assembly units 50 are stacked so that one system is divided and produced.

(Modification example of separation part (1))
FIG. 14 is a diagram illustrating a modification example (1) of the separation unit of the manufacturing apparatus 100 according to the above-described embodiment. FIG. 15A is a diagram showing a main part of a modified example (1) of the separation unit, and FIG. 15B is a diagram showing a pressing piece of the pressing member shown in FIG. 15A. In addition, the same code | symbol is attached | subjected to the member same as embodiment mentioned above, and description is abbreviate | omitted. The dimensional ratios in the drawings are exaggerated for convenience of explanation, and are different from the actual ratios. Hereinafter, a modification example (1) of the separation unit will be described.

  The separation unit 1250 in the modified example (1) is different from the separation unit 250 in the above-described embodiment in that a dust collection unit 1252 for collecting chips generated by cutting the separator cutting blade 1251 is provided. Yes. In addition, the first separator base material 1211 and the second separator base material 1231 in which a heat-resistant material is applied to at least one surface are also different from the above-described embodiment.

  As for the 1st separator base material 1211 and the 2nd separator base material 1231, the heat resistant material is apply | coated to at least one surface. By applying a separator coated with a heat-resistant material, the heat resistance of the power generation element 11 and thus the battery can be increased. As the material for the heat-resistant material, for example, ceramic formed by molding an inorganic compound at a high temperature is used. The ceramic is made of a porous material formed by bonding a ceramic particle such as silica, alumina, zirconium oxide, titanium oxide or the like and a binder. The material of the heat-resistant material is not limited to ceramics and can be used as appropriate.

  Here, when both the separator base materials 1211 and 1231 coated with ceramics (ceramic coating) are cut, in addition to the chips of the separator material itself, powder due to chipping of the coated ceramics is also generated as chips. Easy to do. If the ceramic powder adheres to a bearing of an unillustrated device such as a conveyor or a suction hole of an unillustrated vacuum suction / conveying device, the ceramic powder may cause clogging or the like. Further, when powder adheres to the surface of a conveyor (not shown) or a handling hand (not shown), the attached powder may be mixed into the battery stack. For this reason, in the modified example (1), the dust collecting part 1252 is used for collecting dust from the separator material free end material and ceramic powder generated when the separator base materials 1211 and 1231 are cut. Is provided.

  In addition, also in the above-described embodiment using the first separator base material 211 and the second separator base material 231 that are not subjected to the ceramic coating, the dust collection part is provided and the separator base materials 211 and 213 are generated when the separator base material is cut. Needless to say, chips may be collected.

  Referring to FIG. 14, the separation unit 1250 separates the separator substrates 1211 and 1231 that connect the adjacent subassembly units 51 stacked on the adjacent support surfaces 1202 a to 1202 d of the stacked jig unit 1201. It has a blade 1251 and a dust collecting part 1252 that collects dust generated when both separator base materials 1211 and 1231 are cut. The separation unit 1250 further includes a pressing member 1253 that presses both sides of the cut portion when the first separator substrate 1211 and the second separator substrate 1231 are cut.

  The dust collection unit 1252 includes a dust collector 1300 including a dust collection nozzle 1301, a suction flow path 1302, a dust collection filter 1303, and a vacuum pump 1304.

  The dust collection nozzle 1301 is connected to a vacuum pump 1304 via a suction flow path 1302. By driving the vacuum pump 1304, chips are sucked together with the surrounding air through the dust collection nozzle 1301.

  The dust collection filter 1303 is disposed between the suction flow path 1302 and the vacuum pump 1304 and captures chips sucked through the suction flow path 1302. The captured chips are discarded artificially or automatically every predetermined period.

  In order to reduce as much as possible the remaining chips or floating chips in the separating unit 1250, it is preferable that the dust collecting unit 1252 is always operated. However, the present invention is not limited to the case where the dust collecting unit 1252 is always operated. For example, the dust collection unit 1252 may be controlled by the control unit 260 so that the dust collection unit 1252 is operated in accordance with the timing at which the separator cutting blade 1251 cuts both the separator base materials 1211 and 1231.

  The separate cutting blade 1251 is a blade (hot blade) that has a sharp tip and is heated to a predetermined temperature. Although heating temperature changes with separator base materials 1211 and 1231 to apply, it is 220-250 degreeC, for example. Although the material of the separate cutting blade 1251 is not specifically limited, For example, it can form from a metal. An electric heater (not shown) for heating the separator cutting blade 1251 is disposed inside the separator cutting blade 1251. The electric heater is energized and controlled by the control unit 260 so that the separator cutting blade 1251 is heated in accordance with the timing at which the separator bases 1211 and 1231 are cut. The separator cutting blade 1251 presses the heated sharp tip 1251a against several layers (for example, 15 to 40 layers) of the separator bases 1211 and 1231 to cut the separator bases 1211 and 1231. When the material of both separator bases 1211 and 1231 is polypropylene, several layers (15 to 40 layers) of separator bases 1211 and 1231 are cut, for example, over about 1 second.

  An urging member 1257 is attached to the base end 1251b of the separator cutting blade 1251 as shown in FIG. Separator cutting blade 1251 is attached to holding member 1258 via biasing member 1257. The urging member 1257 is made of, for example, a spring, and urges the separator cutting blade 1251 with a resilient force in a direction in which the separator cutting blade 1251 is pressed toward the separator bases 1211 and 1231. A stopper (not shown) that restricts the forward limit position of the separator cutting blade 1251 against the elastic force of the urging member 1257 is provided on the holding member 1258. A drive member 1259 that moves the holding member 1258 forward and backward relative to the separator base materials 1211 and 1231 is attached to the rear of the holding member 1258. The drive member 1259 is composed of a fluid pressure cylinder that operates by fluid pressure such as high-pressure air, for example. The driving member 1259 is controlled by the control unit 260. The drive member 1259 moves the holding member 1258 forward, thereby pushing the separator cutting blade 1251 from the initial position to the lower left in FIG. 15A via the biasing member 1257. The drive member 1259 moves the separator cutting blade 1251 diagonally upward to the right in FIG. 15A via the biasing member 1257 by moving the holding member 1258 backward, and returns it to the initial position.

  As shown in FIGS. 14 and 15A, the pressing member 1253 has a clamp structure, a pair of pressing pieces 1255 in which a vent hole 1254 is formed, and a receiving plate 1209 that receives the pressing force of the pressing piece 1255. Have. The pair of pressing pieces 1255 operate so as to press both separator bases 1211 and 1231 before the separator cutting blades 1251 cut both separator bases 1211 and 1231. The receiving plate 1209 is provided at each corner 1208 a to 1208 d of the stacking jig 1201. The receiving plate 1209 also functions as a counterpart receiving the pressing force of the blade edge 1251a of the separator cutting blade 1251.

  The pair of pressing pieces 1255 are arranged so as to sandwich the separator cutting blade 1251 therebetween. A dust collection nozzle 1301 is arranged so as to face the vent hole 1254 of the pressing piece 1255. The dust collector 1252 collects chips through the vent hole 1254. The opening area of the vent hole 1254 is set to a size that is not blocked by chips. As shown in FIG. 15B, the vent hole 1254 has a rectangular shape. However, the shape of the vent hole 1254 is not limited to this case, and an appropriate shape can be selected as long as chips can be collected.

  As shown in FIG. 15A, the pressing piece 1255 is slidably accommodated in an accommodation groove 1260 formed in the holding member 1258 on the base end side. An urging member 1261 is disposed between the base end 1255a of the pressing piece 1255 and the bottom 1260a of the receiving groove 1260. The urging member 1261 is made of, for example, a spring, and urges the pressing piece 1255 with a resilient force in a direction of pressing the pressing piece 1255 toward the separator bases 1211 and 1231. A stopper (not shown) that restricts the forward limit position of the pressing piece 1255 against the elastic force of the urging member 1261 is provided on the holding member 1258.

  The pressing piece 1255 is provided with a rubber pad 1256 at the tip on the side facing the separator bases 1211 and 1231. By providing the rubber pad 1256, the pressing piece 1255 can press both the separator bases 1211 and 1231 without sliding on the surfaces of the both separator bases 1211 and 1231.

  Next, the operation of the separation unit 1250 according to the modification example (1) will be described.

  The vacuum pump 1304 is always driven, and the dust collecting unit 1252 is always operated. When both separator base materials 1211 and 1231 connecting the sub assembly units 51 reach a predetermined position of the separating portion 1250 by the rotation of the stacking jig 1201, the rotation of the stacking jig 1201 is stopped.

  The drive member 1259 is controlled by the control unit 260 and moves the holding member 1258 forward toward the separator base materials 1211 and 1231. When the holding member 1258 moves forward, the tip ends of the pair of pressing pieces 1255 press the separator base materials 1211 and 1231 before the separator cutting blade 1251 reaches. When the holding member 1258 further moves forward, the base end sides of the pair of pressing pieces 1255 are pushed into the housing groove 1260 of the holding member 1258, and the biasing member 1261 is compressed. The pair of pressing pieces 1255 presses both sides of the cut portion by the elastic force of the biasing member 1261 being biased. Thereby, the tension | tensile_strength has generate | occur | produced in the cut location of the separator base materials 1211 and 1231 which connect the sub assembly units 51 mutually. The pressing piece 1255 comes into contact with both separator bases 1211 and 1231 through the rubber pad 1256. Accordingly, the pressing piece 1255 can reliably press the separator bases 1211 and 1231 without slipping the surfaces of the separator bases 1211 and 1231.

  The separator cutting blade 1251 is pushed from the initial position in the diagonally downward left direction in FIG. 15A, and the tip 1251a reaches the separator bases 1211 and 1231. When the holding member 1258 further moves forward, the biasing member 1257 is compressed. The separator cutting blade 1251 cuts the first separator base material 1211 and the second separator base material 1231 when the elastic force of the biasing member 1257 is biased. At this time, tension is generated at the cut portion by the pair of pressing pieces 1255. Therefore, the separator cutting blade 1251 can smoothly and reliably cut the cut portions of the separator base materials 1211 and 1231.

  When both separator base materials 1211 and 1231 are cut, scraps such as end materials and ceramic powder that are free of separator material are generated.

  Since the pair of pressing pieces 1255 presses both sides of the cut portion, scattering of chips generated during cutting can be suppressed.

  Then, the generated chips are sucked into the dust collecting nozzle 1301 through the vent hole 1254 of the pressing piece 1255 and captured by the dust collecting filter 1303 through the suction flow path 1302. Even when the ceramic-coated separator base materials 1211 and 1231 are used as in the modified example (1), as a result of being able to capture chips by the dust collecting unit 1252, clogging or failure caused by ceramic powder or the like occurs. Can be suppressed. Furthermore, it is possible to prevent a situation in which the battery stack is mixed.

  When the separator cutting blade 1251 finishes cutting the first separator base material 1211 and the second separator base material 1231, the driving member 1259 is controlled by the control unit 260 and retracts the holding member 1258 so as to be separated from the cutting portion. Moving. When the holding member 1258 moves backward, the separator cutting blade 1251 moves in the diagonally upper right direction in FIG. 15A and returns to the initial position.

  When the holding member 1258 is further moved backward, the pair of pressing pieces 1255 are also moved in the diagonally upper right direction in FIG. 15A and returned to the initial position, similarly to the separator cutting blade 1251.

  When the separator cutting blade 1251 and the pressing piece 1255 return to the initial position, the stacking jig 1201 rotates under the control of the control unit 260. By the rotation of the stacking jig 1201, the first separator base material 1211 and the second separator base material 1231 at the next corners reach the vicinity of the separation part 1250. Then, the separation unit 1250 cuts the next corner by the same procedure as described above.

  As described above, the separation unit 1250 of the modification example (1) includes the dust collection unit 1252 that collects dust generated when the first separator base material 1211 and the second separator base material 1231 are cut. is there. For this reason, even when the ceramic-coated separator base materials 1211 and 1231 are used, the dust collector 1252 can capture scraps such as end material and ceramic powder that are free of separator material. As a result, the occurrence of clogging or failure due to ceramic powder or the like can be suppressed, and the situation of being mixed into the battery stack can also be prevented.

  Since the pressing member 1253 that presses both sides of the cut portion when the both separator bases 1211 and 1231 are cut, tension can be generated at the cut portion. Therefore, the separator cutting blade 1251 can smoothly and reliably cut the cut portions of the separator base materials 1211 and 1231. Furthermore, since the pressing piece 1255 is pressing down the both sides of a cutting location, the scattering of the chip | tip generated at the time of a cutting | disconnection can be suppressed.

  The pressing member 1253 has a pressing piece 1255 in which a vent hole 1254 is formed, and the dust collecting portion 1252 collects chips through the vent hole 1254. Therefore, each of cutting and dust collection can be performed smoothly and reliably without the pressing member 1253 hindering when the separator base materials 1211 and 1231 are cut.

  And both separator base materials 1211 and 1231 are coated with ceramics as a heat-resistant material on at least one surface. By applying the separator 30 to which the heat-resistant material is applied, it is possible to improve the heat resistance of the power generation element 11 and the battery.

(Modification example of separation part (2))
FIG. 16 is a diagram illustrating a modification (2) of the separation unit of the manufacturing apparatus 100 according to the above-described embodiment. FIG. 17 is an enlarged cross-sectional view taken along line 17-17 in FIG. In addition, the same code | symbol is attached | subjected to the member same as embodiment mentioned above and modification order (1), and description is abbreviate | omitted. The dimensional ratios in the drawings are exaggerated for convenience of explanation, and are different from the actual ratios. Hereinafter, a modification example (2) of the separation unit will be described.

  The separation unit 2250 in the modification example (2) is different from the separation unit 1250 in the modification example (1) in that the first separator base material 1211 and the second separator base material 1231 are cut by the laser 2251. Further, the separation unit 2250 is different from the separation unit 1250 of the modified example (1) not only in the dust collector 1300 but also in collecting dust by using the grooves 2211 included in the stacking jig 2201.

  Referring to FIG. 16, the separation unit 2250 according to the modification example (2) includes a dust collection unit 2252 that collects dust generated when the first separator base material 1211 and the second separator base material 1231 are cut. Have. The dust collection unit 2252 collects chips using not only the dust collector 1300 but also grooves 2211 (described later) of the stacking jig 2201.

  The separation unit 2250 is a laser oscillator for oscillating a laser 2251 that cuts both separator base materials 1211 and 1231 that connect adjacent sub-assembly units 51 stacked on adjacent support surfaces 202a to 202d of the stacking jig 2201. 2400. A laser 2251 is a carbon dioxide laser, and when the separator base material 1211 and 1231 are polypropylene, the separator is cut at an output of 30 w, a wavelength of 10.6 μm, and a cutting speed of about 400 mm / second. When the width of the separator composed of the first separator 1211 and the second separator 1231 is about 200 mm, one pass takes 0.5 seconds, but when the number of separator layers is 30 to 40 layers, 5 passes. Cut repeatedly with repeated passes. Since the resin base material tends to transmit laser light, it is cut in multiple passes. The operation of the separation unit 2250 is controlled by the control unit 260. In the modification example (2) of the separation unit, the case where the laser 2251 is controlled by the above value is exemplified, but the present invention is not limited to this and can be changed as appropriate.

  As shown in FIG. 16, the pressing member 1253 has a clamp structure, and has a pair of pressing pieces 1255 in which the vent holes 1254 are formed, and a receiving plate 2210 that receives the pressing force of the pressing pieces 1255. The pair of pressing pieces 1255 operate so as to press both separator bases 1211 and 1231 before the separators 1211 and 1231 are cut by the laser oscillator 2400. The receiving plate 2210 is provided at each corner 2208 a to 2208 d of the stacking jig 2201. The receiving plate 2210 is formed on both sides of each groove 2211.

  In the separation unit 2250, the pressing piece 1255 is connected to the driving member 2262. The drive member 2262 is composed of a fluid pressure cylinder, for example. The driving member 2262 is controlled by the control unit 260. The drive member 2262 is used to move the pressing piece 1255 forward and backward in the diagonally downward left direction in FIG. The drive member 2262 moves the pressing piece 1255 forward. As a result, the pressing piece 1255 presses both separator bases 1211 and 1231 on both sides of the cut portion. On the other hand, when the driving member 2262 moves the pressing piece 1255 backward, the pressing piece 1255 moves away from both the separator bases 1211 and 1231 and returns to the initial position.

  The stacking jig 2201 has a groove 2211 between adjacent support surfaces 202 a to 202 d, and the dust collector 2252 collects chips through the grooves 2208 of the stacking jig 2201. As shown in FIG. 17, each groove 2211 is formed with a dust collection hole 2212.

  Each groove 2211 of the stacking jig 2201 is connected to a suction channel 2213 inside the stacking jig 2201 as shown in FIG. The suction channel 2213 is connected to the vacuum pump 207 via the suction channel 2214. Further, the suction flow path 2213 and the suction flow path 2214 are connected via a rotation shaft 2204. The rotating shaft 2204 is, for example, a donut-shaped shaft having a hollow center, and is connected to the driving unit 203 (see FIG. 5). Based on the suction of air by driving the vacuum pump 207, the dust collection holes 2212 of each groove 2211 collect chips.

  The dust collection filter 2215 is disposed between the suction flow path 2214 and the vacuum pump 207 and captures the chips sucked through the suction flow paths 2213 and 2214. The captured chips are discarded artificially or automatically every predetermined period.

  Next, the operation of the separation unit 2250 according to the modification example (2) will be described.

  The vacuum pump 207 is always driven, and the dust collecting unit 2252 is always operated. When both separator base materials 1211 and 1231 connecting the subassembly units 51 reach a predetermined position of the separating portion 1250 by the rotation of the stacking jig 2201, the rotation of the stacking jig 2201 is stopped.

  The driving member 2262 is controlled by the control unit 260 and moves the pressing piece 1255 forward toward the separator base materials 1211 and 1231. The front ends of the pair of pressing pieces 1255 press the separator base materials 1211 and 1231. Thereby, the tension | tensile_strength has generate | occur | produced in the cut location of the separator base materials 1211 and 1231 which connect the sub assembly units 51 mutually. The pressing piece 1255 comes into contact with both separator bases 1211 and 1231 through the rubber pad 1256. Accordingly, the pressing piece 1255 can reliably press the separator bases 1211 and 1231 without slipping the surfaces of the separator bases 1211 and 1231.

  A laser 2251 is oscillated from the laser oscillator 2400 to cut the first separator base material 1211 and the second separator base material 1231. At this time, tension is generated at the cut portion by the pair of pressing pieces 1255. Therefore, the laser 2251 can cut the cut portions of the separator base materials 1211 and 1231 smoothly and reliably.

  When both separator base materials 1211 and 1231 are cut, scraps such as end materials and ceramic powder that are free of separator material are generated.

  Since the pair of pressing pieces 1255 presses both sides of the cut portion, scattering of chips generated during cutting can be suppressed.

  Then, the generated chips are sucked into the dust collecting nozzle 1301 through the vent hole 1254 of the pressing piece 1255 and captured by the dust collecting filter 1303 through the suction flow path 1302. In the modified example (2), the dust is collected not only through the dust collector 1300 but also through the grooves 2211 formed between the adjacent support surfaces 202a to 202d of the stacking jig 2201, so that it is more reliable. It is possible to collect chips. Even when the ceramic-coated separator base materials 1211 and 1231 are used, chips can be captured by the dust collecting unit 1252, so that the occurrence of clogging or failure due to ceramic powder or the like can be suppressed. Furthermore, it is possible to prevent a situation in which the battery stack is mixed.

  When the laser 2251 finishes cutting the first separator substrate 1211 and the second separator substrate 1231, the operation of the laser oscillator 2400 is stopped. The driving member 2262 is controlled by the control unit 260, and moves the pressing piece 1255 backward so as to be separated from the cutting portion. The pressing piece 1255 moves to the upper right in FIG. 16 and returns to the initial position.

  When the pressing piece 1255 returns to the initial position, the stacking jig 2201 rotates under the control of the control unit 260. Due to the rotation of the stacking jig 2201, the first separator base material 1211 and the second separator base material 1231 at the next corners reach the vicinity of the separation part 2250. Then, the separation unit 2250 cuts the next corner by the same procedure as described above.

  As described above, since the separation unit 2250 of the modification example (2) is provided with the dust collecting part 1252 as in the modification example (1), the separator material free end material and chips such as ceramic powder are removed. It can be captured by the dust collector 1252. As a result, the occurrence of clogging or failure due to ceramic powder or the like can be suppressed, and the situation of being mixed into the battery stack can also be prevented.

  Since it has the pressing member 1253 that presses both sides of the cut portion when cutting both the separator base materials 1211 and 1231, tension is generated at the cut portion of both the separator base materials 1211 and 1231 to cut smoothly and reliably. Can do. Furthermore, since the pressing piece 1255 is pressing down the both sides of a cutting location, the scattering of the chip | tip generated at the time of a cutting | disconnection can be suppressed.

  Since the dust collecting part 1252 collects chips through the vent hole 1254, the cutting and dust collection can be performed smoothly and without the pressing member 1253 being obstructed when the separator base materials 1211 and 1231 are cut. It can be done reliably.

  In the modified example (2), the dust is collected not only through the dust collector 1300 but also through the grooves 2211 formed between the adjacent support surfaces 202a to 202d of the loading jig 2201. Chips can be collected.

  Similarly to the modification example (1), the heat resistance of the power generation element 11 and the battery can be increased by applying the separator 30 coated with a heat-resistant material.

  In the modified example (2), since the laser 2251 is used for cutting, the separator cutting blade is not worn as in the case of using the separator cutting blades 251 and 1251, and the number of maintenance of the separation unit can be reduced.
