JP 2007-242506 A

  In the electrode plate package manufacturing apparatus 101, the first separator 11, the battery electrode plate 21, and the second separator 2 are held and conveyed while being sucked from the conveying belt 131. A decompression chamber may be provided on the back side of the conveyor belt 131 in order to suppress a sudden change in suction force.

However, in the case of a single space where the decompression chamber communicates from the separator transfer section 150 to the separator joint section 165, it is necessary to align the suction force with the suction force in an area where the greatest suction force is required. In order to increase the suction force, it is necessary to increase the driving force for driving the conveyor belt 131, and it becomes difficult to smoothly convey the separator, the battery electrode plate, and the like.
In addition, the force applied between the conveyor belt 131 and the decompression chamber or between the conveyor belt 131 and the drive roller that drives the conveyor belt 131 increases, and the amount of foreign matter generated due to wear of each member may increase. There is. When this foreign substance is mixed into the laminated battery 7, it leads to product quality deterioration.

  The present invention solves the above problems, and can smoothly transport separators, electrode plates for batteries, and the like, and can suppress the generation of foreign matters resulting from the transportation. An object is to provide a body manufacturing apparatus.

In order to solve the above-mentioned problem, an apparatus for manufacturing an electrode plate package of the present invention comprises:
An apparatus for manufacturing an electrode plate package having a structure in which a battery electrode plate is accommodated in a bag-shaped separator comprising a first separator and a second separator,
A transport unit having an annular transport belt provided with a plurality of suction holes, and a plurality of decompression chambers arranged along the moving direction of the transport belt on the back side of the transport belt;
In a region before the battery electrode plate is placed, a separator transfer unit that transfers the first separator placed on the surface side of the conveyor belt;
A battery electrode plate mounting portion for mounting the battery electrode plate on the first separator;
A separator stacking section for stacking the second separator on the first separator so as to cover the battery electrode plate;
By joining the first separator and the second separator to each other around the battery electrode plate, the battery electrode is placed in a bag-shaped separator composed of the first separator and the second separator. A separator joint that forms the electrode plate package in which a plate is accommodated, and
Among the plurality of decompression chambers, a predetermined decompression chamber is configured so that the pressure can be set.
Here, the predetermined decompression chamber configured to be able to set the pressure may be all the decompression chambers of the plurality of decompression chambers, or a part of the plurality of decompression chambers The reduced pressure chamber may be used.

In the apparatus for manufacturing an electrode plate package according to the present invention, the decompression chambers are provided at positions corresponding to at least the separator transfer unit, the battery electrode plate mounting unit, the separator stacking unit, and the separator bonding unit, respectively.
The decompression chamber provided at a position corresponding to the battery electrode plate mounting portion, the separator stacking portion, and the separator joining portion is lower than the decompression chamber provided at a position corresponding to the separator transfer portion. It is preferable to reduce the pressure so as to be a pressure.

  Since only the first separator is sucked in the separator transfer section, the suction force can be made smaller than that in other areas. As a result, the driving force for driving the transport belt can be minimized, and the generation of foreign matters due to transport can be further suppressed.

Further, when the transport belt is formed using a magnetic metal material,
The conveyance unit has a metal powder collection magnet for collecting metal material powder, and the metal powder collection magnet has a predetermined gap so as not to contact the conveyance belt on the front surface side or the back surface side of the conveyance belt. It is preferable that they are arranged apart.

  With the above configuration, when a conveyor belt formed using a magnetic metal material is operated, metal material powder generated by rubbing between the conveyor belt and the drive roller of the conveyor belt is recovered by the metal powder recovery magnet. Therefore, the adhesion of the metal material powder to the electrode plate package and the mixing of the metal material powder into the stacked battery can be suppressed.

  In addition, the conveyance unit includes a resin guide unit that guides the conveyance belt while being in contact with the conveyance belt on a front surface side or a back surface side of the conveyance belt, and the metal powder collection magnet is arranged on the guide unit. It is preferable to be provided.

  By disposing the resin guide portion in contact with the conveyance belt, the conveyance belt moves along the guide portion, and fluttering of the conveyance belt during conveyance can be suppressed. Thereby, transfer of a separator with high accuracy, placement of a battery electrode plate, stacking and joining of separators can be realized. In addition, by stabilizing the conveyance of the conveyance belt, it is possible to suppress the generation of foreign matters due to the conveyance.

  The decompression chamber includes a belt support portion having a flat portion that supports the transport belt, and the belt support portion includes communication holes that communicate with the plurality of suction holes of the transport belt. It is preferable.

  Since the decompression chamber includes the belt support portion including the flat portion and the communication hole, the suction force from the transport belt during transport can be secured and the flatness of the transport belt can be kept within a predetermined range. Thereby, transfer of a separator with high accuracy, placement of a battery electrode plate, stacking and joining of separators can be realized.

  Moreover, it is preferable that a support roller for supporting the transport belt is provided inside the decompression chamber.

  By providing a support roller inside the decompression chamber, it is possible to smooth the movement of the conveyor belt and suppress the generation of foreign matters due to the conveyance.

Since the apparatus for manufacturing an electrode plate package of the present invention can set an appropriate pressure for a predetermined decompression chamber, the suction force does not increase more than necessary. Therefore, the driving force for driving the conveyor belt can be reduced, and smooth conveyance can be realized. In addition, it is possible to suppress the generation of foreign matters due to conveyance such as wear generated between the conveyance belt and the decompression chamber or between the conveyance belt and the sprocket roller.
In addition, it is possible to set an appropriate pressure for each decompression chamber, and it is possible to avoid an excessive increase in suction force. It is also possible to suppress the generation of foreign matters due to wear during the period.

As shown in FIG. 1, the electrode plate package 5 is a structure in which a battery electrode plate (first electrode plate) 21 is accommodated in a bag-like separator 13 composed of a pair of separators 11 and 12. It is.

  The electrode plate package manufacturing apparatus 1 will be described with reference to FIG. The manufacturing apparatus 1 for an electrode plate package includes a transport belt 31 having suction holes and a transport section 30 having a decompression chamber 35 (35a, 35b, 35c, 35d), a separator transport section 50 for transporting the first separator 11, and The battery electrode plate mounting portion 55 for mounting the battery electrode plate 21, the separator stacking portion 60 for stacking the second separator 12, and the separator bonding portion for bonding the first separator 11 and the second separator 12. 65. In addition, in FIG. 3, the cutting | disconnection part 70 which separates the electrode plate package 5a of a multiple state into each electrode plate package 5 is also shown.

  In this embodiment, the direction in which the first separator 11 is transferred by the transfer unit 30 is the transfer direction X, the direction perpendicular to the main surface of the first separator 11 being transferred is the up-down direction Z, and the transfer direction X. A direction perpendicular to the vertical direction Z will be described as a width direction Y.

  The transport unit 30 includes an annular transport belt 31 provided with a plurality of suction holes 32, and a plurality of decompression chambers 35 (35a, 35b, 35c, 35d) arranged on the back surface 31b side of the transport belt 31. Yes.

  The transport belt 31 is for transporting the first separator 11, the battery electrode plate 21 and the second separator 12 while sequentially stacking them. At that time, the first separator 11, the battery electrode plate 21 and the second separator 12 are vacuum-sucked through the suction holes 32 and are transported while being sucked and held on the surface 31 a side of the transport belt 31. In this embodiment, the conveyance belt 31 is configured to be intermittently driven at a predetermined pitch so that the conveyance can be temporarily stopped at the separator joining portion 65.

  The suction holes 32 of the transport belt 31 penetrate from the front surface 31a to the back surface 31b of the transport belt 31, and are formed in a matrix when viewed from the front surface 31a side of the transport belt 31. Examples of the material of the conveyor belt 31 include a metal material and a resin material such as urethane. However, in consideration of durability, the material is formed from a metal material (magnetic metal material) such as stainless steel as a constituent material. It is preferable to use the same.

  At both ends of the conveyance belt 31 in the width direction Y, feed holes (not shown) are provided along the conveyance direction X at equal intervals. At both ends of the conveyance belt 31 in the conveyance direction X, sprocket rollers 33 for circulatingly driving the conveyance belt 31 are arranged. A protrusion (not shown) is provided on the outer periphery of the sprocket roller 33. The protrusions move in the rotational direction while meshing with the feeding holes of the conveyor belt 31, whereby the conveyor belt 31 is driven to circulate.

  A plurality of decompression chambers 35 (35a, 35b, 35c, 35d) are arranged along the moving direction (conveying direction X) of the conveying belt 31 on the back surface 31b side of the conveying belt 31. Specifically, the decompression chambers 35a, 35b, 35c, and 35d are disposed at positions corresponding to the separator transfer unit 50, the battery electrode plate mounting unit 55, the separator stacking unit 60, and the separator joining unit 65, respectively.

Each decompression chamber 35 includes a first separator, a second separator, and a battery, which are objects to be conveyed, in the separator transfer unit 50, the battery electrode plate mounting unit 55, the separator stacking unit 60, and the separator bonding unit 65. The electrode plate (first electrode plate) and the like are stably held on the transport belt by vacuum suction, and the transport belt 31 itself is sucked to suppress fluttering, thereby enabling stable transport.
Note that the decompression chamber 35 is configured to be able to suppress a rapid change in suction force by having a predetermined space.

  Vacuum regulators 36a, 36b, 36c, and 36d are provided between the decompression chambers 35a, 35b, 35c, and 35d and a vacuum source (not shown), respectively. Thereby, it is comprised so that the pressure in the decompression chamber 35 can be set, respectively. Instead of using the vacuum regulator 36, a vacuum pump or the like may be used.

The decompression chambers 35b, 35c, and 35d corresponding to the battery electrode plate mounting portion 55, the separator stacking portion 60, and the separator joining portion 65 are decompressed to a pressure lower than that of the decompression chamber 35a corresponding to the separator transfer portion 50. It is configured.
That is, the suction force in the separator transfer unit 50 is set to be smaller than the suction force in other regions (battery electrode plate mounting portion 55, separator stacking portion 60, separator joining portion 65).

In particular,
The vacuum pressure in the decompression chamber 35a corresponding to the separator transfer unit 50, which is the region to which the first separator 11 is supplied, is 401 to 500 mmHg,
The vacuum pressure of the decompression chamber 35b corresponding to the decompression chamber corresponding to the battery electrode plate mounting portion 55 is 200 to 300 mmHg,
The vacuum pressure of the decompression chamber 35c corresponding to the separator overlap portion 60 on which the second separator 12 is overlapped is 200 to 300 mmHg,
The vacuum pressure in the decompression chamber 35d corresponding to the separator joint 65 is 301 to 400 mmHg.
It is comprised so that.

  In the decompression chamber 35a corresponding to the separator transfer unit 50, which is a region to which the first separator 11 is supplied, the first separator 11 is placed at a predetermined position on the transport belt 31 without applying a large suction force. Since it can convey while hold | maintaining, reliable conveyance can be performed by the above vacuum degrees.

  In addition, the decompression chamber 35 b corresponding to the decompression chamber corresponding to the battery electrode plate mounting portion 55 is configured to place the first separator 11 and the battery electrode plate (first electrode plate) 21 on the transport belt 31. Since it is necessary to carry while maintaining the positional relationship between the two while being held at a predetermined position, it is necessary to perform suction with a force larger than that of the above-described decompression chamber 35a.

  Further, in the decompression chamber 35c corresponding to the separator stacking portion 60 on which the second separator 12 is stacked, the first separator 11, the battery electrode plate (first electrode plate) 21, and the second separator 12 are transferred to the transport belt. Since it is necessary to transport the members while maintaining the positional relationship between them while holding them at a predetermined position on 31, it is necessary to suck them with a large force equivalent to that of the above-described decompression chamber 35 b.

  In addition, since the decompression chamber 35d corresponding to the separator joining portion 65 is joined, it is necessary to reliably maintain the positional relationship between the respective members. The vacuum chambers 35b and 35c are preferably sucked with a smaller force. Therefore, in this embodiment, suction is performed up to the vacuum pressure as described above.

  The decompression chamber 35 of this embodiment has a belt support portion 37 that supports the transport belt 31. The belt support portion 37 includes a flat portion 37 a that contacts the back surface 31 b of the conveyance belt 31 and communication holes 38 that communicate with the plurality of suction holes 32 of the conveyance belt 31.

  The flat surface portion 37a of the belt support portion 37 is formed to have a predetermined flatness by grinding or the like, and is formed so as to avoid the plurality of suction holes 32 formed in a matrix when viewed from the vertical direction Z. Has been. Further, the communication hole 38 is formed by being divided into a plurality of grooves so as to correspond to each row of the plurality of suction holes 32.

  In the separator transfer part 50 which comprises the manufacturing apparatus 1 of the electrode plate packaging body concerning this embodiment, in the area | region before the battery electrode plate 21 is mounted, it is mounted in the surface 31a side of the conveyance belt 31. One separator 11 is transferred. The first separator 11 is fed out from the separator roll 51 as a belt-like body, and then placed on the transport belt 31 by the pressing roller 52. The first separator 11 is held on the conveyor belt 31 by the suction force from the conveyor belt 31. In addition, the shape of the 1st separator 11 is not restricted to a strip | belt-shaped body, The thing cut into the rectangular shape previously may be sufficient.

  In the battery electrode plate mounting portion 55, the battery electrode plate 21 sucked by the suction head 56 is placed on the first separator 11 at a predetermined pitch. This predetermined pitch is the same as the pitch when the conveyor belt 31 is intermittently driven. Since the first separator 11 is a porous material, the battery electrode plate 21 is sucked and held on the transport belt 31 via the first separator 11. In addition, the shape of the battery electrode plate 21 is rectangular, and the dimension of the battery electrode plate 21 in the width direction Y is smaller than the dimension of the first separator 11 in the width direction Y.

In the separator stacking unit 60, the second separator 12 is stacked on the first separator 11 so as to cover the placed battery electrode plate 21. The second separator 12 is fed out as a strip from the separator roll 61 and then placed on the first separator 11 and the battery electrode plate 21 by the pressing roller 62. The second separator 12 is also held on the transport belt 31 by the suction force from the transport belt 31 via the first separator 11. In addition, the shape of the 2nd separator 12 is not restricted to a strip | belt-shaped body, The thing cut into the rectangular shape previously may be used.
Since the dimension in the width direction Y of the first separator 11 and the second separator 12 is larger than the dimension in the width direction Y of the battery electrode plate 21, the battery electrode of the first separator 11 and the second separator 12 is used. The portions located in the outer regions of the four sides of the plate 21 are attracted to the surface of the conveyor belt 31 by suction and are securely held while being sandwiched between the first separator 11 and the second separator 12. It becomes.

In the separator joint portion 65, the first separator 11 and the second separator 12 are joined to each other around the outer periphery of the battery electrode plate 21. Specifically, by pressing a pressure bonding head 66 having a plurality of heater chips, a plurality of locations of the stacked separators are thermocompression bonded.
Thereby, the electrode plate package 5a in a state where the battery electrode plate 21 is accommodated in the bag-like separator 13 composed of the first separator 11 and the second separator 12 is formed. When a strip-shaped separator is used, the electrode plate package 5a is still in a multiple state at this point.
In such a multiple state, a sufficient margin can be taken around the thermocompression bonding portion between the first separator and the second separator by sufficiently taking the pitch between the battery electrode plates 21. . Thereby, heat can be released to the blank portion at the time of thermocompression bonding, and wrinkles and unevenness generated by heat accumulation in the thermocompression bonding portion can be suppressed.

The electrode plate package manufacturing apparatus 1 shown in FIG. 3 includes a cutting unit 70 on the downstream side (conveying direction X) of the separator joining unit 65. The multi-electrode plate package 5a is held by the suction head 72 and further conveyed downstream. Then, the 1st separator 11 and the 2nd separator 12 which were piled up are cut | disconnected by dropping the cutting blade 71 between the adjacent electrode plates 21 for batteries. Thereby, the electrode plate package 5a in a multiple state is divided, and the electrode plate package 5 separated into individual pieces is formed.
During the transport by the suction head 72, the suction head 72 is moved in synchronization with the intermittent drive of the transport belt 31 with the electrode plate package 5a raised from the surface of the transport belt 31 by a predetermined distance (for example, 1 mm). Is preferred. Thereby, the electrode plate package 5a can be peeled from the transport belt 31 without causing wrinkles or slack in the first separator and the second separator. Then, by cutting the first separator and the second separator in this state, it is possible to obtain the separated electrode plate package 5 having good dimensional accuracy (for example, accuracy of ± 0.2 mm or less).
In addition, in the separator transfer part 50 and the separator overlap part 60, when a rectangular separator is used, this cutting part 70 does not need to be provided.

  FIG. 4 is a view for explaining the laminating apparatus 2 for laminating the electrode plate package 5 and the second electrode plate 22. The separated electrode plate package 5 is conveyed to the further laminating stage 81 by the suction head 72 described above. On the other hand, the second electrode plate 22 cut into a rectangular shape in advance is transported to the stacking stage 81 by another suction head 82. On this lamination | stacking stage 81, the laminated body 6 is formed by alternately laminating | stacking the electrode plate package 5 and the 2nd electrode plate 22. As shown in FIG. In addition, you may arrange | position another rectangular separator in the uppermost layer or the lowest layer as needed.

  The laminated body 6 formed in this way is accommodated in the exterior member 9, and after the electrolyte solution 8 is injected, the exterior member 9 is sealed, whereby a multilayer battery 7 as shown in FIG. 2 is produced. .

  In this embodiment, since a plurality of decompression chambers 35 are provided and each pressure can be set, an appropriate pressure can be set for each decompression chamber 35, and the suction force is more than necessary. An increase in size can be avoided. Therefore, the driving force for driving the conveyor belt 31 can be reduced, and smooth conveyance can be realized. In addition, it is possible to suppress the generation of foreign matters due to conveyance such as wear between the conveyance belt 31 and the decompression chamber 35 or between the conveyance belt 31 and the sprocket roller 33.

  Further, the pressure reducing chambers in the battery electrode plate mounting portion 55, the separator stacking portion 60, and the separator joining portion 65 are decompressed so that the pressure is lower than the pressure reducing chamber in the separator transfer portion 50 (so that the suction force is increased). doing. Since only the first separator 11 is sucked by the separator transfer unit 50, the first separator 11 can be stably adsorbed and held even if the suction force is smaller than that of the other regions. As a result, the driving force for driving the transport belt 31 can be minimized, and the generation of foreign matters due to transport can be further suppressed.

  Further, since the decompression chamber 35 includes the belt support portion 37 including the flat portion 37a and the communication hole 38 described above, the suction force from the transport belt 31 during transport is ensured, and the transport belt 31 Straightness can be maintained within a predetermined range. Thereby, the transfer of a separator, the mounting of a battery electrode plate, the stacking and joining of separators can be realized with higher accuracy.

  A decompression chamber 35H shown in FIGS. 6A and 6B is a diagram showing a decompression chamber 35H according to a modification of the decompression chamber 35 shown in FIGS. 5A and 5B. A plurality of support rollers 39 that support the conveyance belt 31 are provided inside the decompression chamber 35H. The support roller 39 rotates following the movement of the conveyance belt 31.

  The support roller 39 has a shape with a plurality of steps, and a plurality of the support rollers 39 are arranged with the width direction Y as an axis. The stepped portion of the support roller 39 is disposed so as not to overlap the suction hole 32 when viewed in the vertical direction Z, and is in contact with the back surface 31 b of the transport belt 31. On the other hand, the portion recessed from the outer periphery of the support roller 39 is disposed so as to overlap the suction hole 32 when viewed in the vertical direction Z and is not in contact with the back surface 31 b of the conveyor belt 31. Thereby, the passage to the suction hole 32 in the decompression chamber 35H is secured.

  By providing the support roller 39 inside the decompression chamber 35H, the suction force of the transport belt 31 during transport can be secured and the movement of the transport belt 31 can be made smooth. Thereby, generation | occurrence | production of the foreign material resulting from conveyance can be suppressed.

  As shown in FIG. 3, the conveyance unit 30 includes a resin guide unit 42 that guides the conveyance belt 31 while being in contact with the conveyance belt 31 on the front surface 31 a side or the back surface 31 b side of the conveyance belt 31.

  By arranging the resin guide portion 42 so as to be in contact with the transport belt 31, the transport belt 31 moves along the guide member 42, and flapping of the transport belt 31 during transport can be suppressed. Thereby, transfer of a separator with high accuracy, placement of a battery electrode plate, stacking and joining of separators can be realized. In addition, since the conveyance of the conveyance belt 31 is stabilized, the generation of foreign matters due to the conveyance can be suppressed. In addition, since the guide part 42 is resin, there is no possibility of generating metal material powder.

  Further, as shown in FIG. 3, the guide portion 42 is provided with a metal powder collection magnet 41 for collecting metal material powder. The metal powder recovery magnet 41 is arranged with a gap so as not to contact the conveyor belt 31 on the front surface 31 a side or the back surface 31 b side of the conveyor belt 31.

  When the conveyor belt 31 is moved, metal material powder may be generated due to rubbing of the conveyor belt 31 and the sprocket roller 33, but the metal material powder can be recovered by the metal powder recovery magnet 41. The adhesion of the metal material powder and the mixing of the metal material powder into the laminated battery 7 can be suppressed.

  The present invention is not limited to the above-described embodiments in other points, and various applications and modifications can be made within the scope of the invention.
