[0022] The present invention is described below by the embodiments of the invention, but the invention involved in the claims is not limited to the following embodiments. In addition, not all of the structures described in the embodiments are necessary as means for solving the problem. For the sake of clarity of the description, the following description and drawings are appropriately omitted and simplified. In addition, in each of the drawings, the same elements are marked with the same figure numbers, and repeated descriptions are omitted as needed.

[0023] <Implementation Method>

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 1 is an overall stereogram of an electrode stacking device 1 according to an embodiment. The electrode stacking device 1 is a device for stacking a plurality of sheet electrodes. The electrode stacking device 1 stacks a plurality of sheet electrodes to manufacture an electrode stack. The electrode stack is used, for example, as a battery mounted on a vehicle. The sheet electrode may be, for example, an electrode of an all-solid-state battery or an electrode of a semi-solid-state battery. The thickness of the sheet electrode may be, for example, about 200 microns to 1000 microns. In addition, in the following description, the sheet electrode is sometimes referred to simply as an electrode.

[0025] Figure 1The electrode stacking device 1 shown in the figure mainly includes a planar motor 10, a conveying device 20, a camera 30, and a control unit 40. In the electrode stacking device 1, the conveying device 20 receives a rectangular electrode M1 and sequentially supplies the received electrode M1 to the planar motor 10. Thus, the planar motor 10 stacks the electrode M1.

[0026] In addition, as a means for convenience in explaining the positional relationship of the components, Figure 1 The right-handed orthogonal coordinate system is marked in . Figure 2 In the following, when an orthogonal coordinate system is used, Figure 1 The X-axis, Y-axis and Z-axis directions of the coordinate system are respectively consistent with the X-axis, Y-axis and Z-axis directions of these orthogonal coordinate systems.

[0027] In the planar motor 10 , a movable element provided on a stator having a flat surface moves on the flat surface. The planar motor 10 has a stator 11 , a laminating movable part 12 , and an operating movable part 13 as main components.

[0028] The stator 11 has a main surface F1 arranged horizontally and a plurality of coils 14 arranged below the main surface F1. The stator 11 generates a magnetic field on the main surface F1 by flowing an electric current in the coils 14. Thus, the planar motor 10 floats the stacking movable part 12 and the operating movable part 13 arranged on the main surface F1, and moves the floated stacking movable part 12 and the operating movable part 13. In addition, the stator 11 can have a plurality of magnetic sensors along the main surface F1. The magnetic sensors are used to detect the positions of the stacking movable part 12 and the operating movable part 13 that float and move above the main surface F1.

[0029] The stator 11 supplies the output of the magnetic sensor to the control unit 40. Thus, the control unit 40 appropriately recognizes the positions of the stacking movable unit 12 and the operating movable unit 13. In addition, the current flowing in the coil 14 of the stator 11 is controlled by the control unit 40. Thus, the control unit 40 appropriately controls the actions of the stacking movable unit 12 and the operating movable unit 13. In addition, the details of the stacking movable unit 12 and the operating movable unit 13 will be described later.

[0030] The transport device 20 is provided above the planar motor 10, and supplies the electrode M1 to the laminating movable portion 12 of the planar motor 10. The transport device 20 includes a rail 21 and a transport portion 22 as main components.

[0031] The rail 21 is formed in an annular shape and guides the engaged transport unit 22. The rail 21 has a straight portion parallel to the main surface F1 so as to face the main surface F1. The transport unit 22 engages with the straight portion of the rail 21 so as to be linearly movable. Figure 1The transport device 20 shown is in an oblong shape including the straight portion. In addition, the rail 21 is provided so that the plane formed by the oblong shape formed by the rail 21 is orthogonal to the main surface F1 and parallel to the direction in which the electrode M1 is transported. Moreover, the transport device 20 has two rails 21 that are parallel to the transport direction (Y-axis direction) of the electrode M1 and arranged side by side. At this time, the distance between the two rails 21 corresponds to the size of the electrode M1. Thus, the transport device 20 can hold the end of the electrode M1.

[0032] The transport unit 22 receives and holds the electrode M1. The transport unit 22 transports the held electrode M1 along the track 21. In addition, the transport unit 22 supplies the transported electrode M1 to the operating movable unit 13. The transport unit 22 has a suspension clamp 23 and a suspension base 24 as main components. The suspension clamp 23 can clamp the electrode M1 between the suspension clamp 23 and the suspension base 24. The suspension clamp 23 is set to be able to switch between a state in which the electrode M1 is clamped and held between the suspension clamp 23 and the suspension base 24 and a state in which the electrode M1 is received or released by an arbitrary mechanism not shown. The suspension base 24 is engaged with the track 21 and moves linearly along the track 21.

[0033] In addition, the conveying device 20 can include a plurality of conveying units 22. Thus, the conveying device 20 can handle, for example, electrodes M1 of various sizes. In addition, the conveying device 20 can continuously convey the electrode M1 by circulating the conveying units 22 along the track 21 formed in a ring shape by moving the plurality of conveying units 22 in the conveying direction. In addition, the conveying device 20 can convey the electrode M1 by, for example, repeatedly supplying the electrode M1 received on the upstream side to the operating movable unit 13 on the downstream side and then moving the conveying unit 22 to the upstream side (i.e., reciprocating the electrode M1).

[0034] In addition, the track 21 may guide the transport unit 22 that moves autonomously. In this case, the transport unit 22 may have a motor for autonomous movement. In addition, the track 21 may also have a movable part such as a belt conveyor for driving the transport unit 22. In this case, the transport unit 22 may be driven by the track 21.

[0035] The camera 30 is installed above the conveying device 20 and is set to shoot the bottom from the installed position. The camera 30 shoots the outer shape of the electrode M1 transported by the conveying device 20 and supplies the generated image data to the control unit 40. Thus, the image data generated by the camera 30 and supplied to the control unit 40 includes information related to the position and inclination of the outer shape of the electrode M1 transported by the conveying device 20. The control unit 40 receives the above-mentioned image data and controls the movable part 12 for stacking and the movable part 13 for operation in a manner corresponding to the position and inclination of the electrode M1 included in the received image data. In addition, the camera 30 may also shoot a mark provided on the electrode M1 instead of the outer shape of the electrode M1.

[0036] The control unit 40 has a control substrate, which includes a computing device such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) and a storage device that stores at least a program for the electrode stacking device 1 to perform the functions of the present disclosure. The control unit 40 controls at least the actions of the stacking movable part 12 and the operating movable part 13 of the planar motor 10. That is, the control unit 40 controls the actions of the stacking movable part 12 and the operating movable part 13 by setting the current flowing in the coil of the stator 11. In addition, the control unit 40 receives image data from the camera 30, and uses the received image data to control the position and inclination of the stacking movable part 12 and the operating movable part 13 in a manner corresponding to the position and inclination of the electrode M1.

[0037] The control unit 40 may also control the movement of the transport device 20. When the control unit 40 controls the movement of the transport device 20, the control unit 40 may perform control to synchronize the movement of the transport unit 22 of the transport device 20 with the movement of the stacking movable unit 12 of the planar motor 10. In addition, the control unit 40 may also control the camera 30. In this case, the control unit 40 may control the pan, tilt, and zoom movement of the camera 30, for example.

[0038] Next, refer to Figure 2 , the stacking movable portion 12 and the operating movable portion 13 are further described. Figure 2 1 is a perspective view of the stacking movable section 12 and the operating movable section 13. The stacking movable section 12 receives and stacks the electrodes M1 supplied by the conveying device 20. At this time, the stacking movable section 12 moves in the conveying direction of the conveying device 20, that is, Figure 2 The movable operating part 13 moves in the direction of the arrow. The movable operating part 13 stops at a position where it can be operatively contacted with the movable stacking part 12. The movable stacking part 12 contacts the movable operating part 13 while moving in the conveying direction. As a result, the movable operating part 13 is in a state of receiving the electrode M1 and is in a state of holding the received electrode M1.

[0039] The laminating movable section 12 includes a first movable element 121 , a base 122 , an electrode holding section 123 , and a driving mechanism 124 as main components.

[0040] The first movable element 121 can be magnetically suspended above the stator 11 and can move above the main surface F1. The first movable element 121 includes a magnet to achieve the above-mentioned function. The magnet is preferably a permanent magnet such as a neodymium magnet. The first movable element 121 supports the base 122, the electrode holding part 123 and the driving mechanism 124 on the upper part.

[0041] The base 122 is a flat plate-shaped member including a main surface for receiving the electrode M1. The base 122 is provided to be movable up and down in order to stack the electrode M1. The base 122 can be supported by an elastic body such as a spring so as to be movable up and down. The base 122 can also be supported by a motor so as to be movable up and down. Thus, the base 122 can be lowered downward according to the number of stacked electrodes M1.

[0042] The electrode holder 123 presses the base 122 provided on the upper part of the first movable element 121 and the electrode M1 supplied to the upper surface of the base 122 from above. The electrode holder 123 is set to perform a predetermined operation by the driving mechanism 124. The predetermined operation will be described later.

[0043] The driving mechanism 124 drives the electrode holding part 123 by receiving an external force. The driving mechanism 124 includes a first rod 125 and a second rod 126. The first rod 125 and the second rod 126 are operated by contacting with an operating part 132 included in the operating movable part 13, thereby driving the electrode holding part 123.

[0044] The operating movable part 13 mainly includes a second movable element 131 and an operating part 132. The second movable element 131 is movable above the main surface F1. The second movable element 131 includes a magnet for floating and moving on the main surface F1, similarly to the first movable element 121. In addition, the second movable element 131 supports the operating part 132.

[0045] The operating portion 132 is fixed to the second movable member 131, and operates the driving mechanism 124 by contacting with the driving mechanism 124. The operating portion 132 in the present disclosure has a cam that engages with the first rod 125 and the second rod 126. Therefore, by the relative position change between the stacking movable portion 12 and the operating movable portion 13, the operating portion 132 of the operating movable portion 13 operates the first rod 125 and the second rod 126 in contact, thereby driving the electrode holding portion 123.

[0046] Next, refer to Figure 3 and Figure 4An example of the operation of the electrode holding unit 123 and the driving mechanism 124 will be described. Figure 3 This is a first side view showing the operation of the stacking movable section 12 and the operating movable section 13 .

[0047] exist Figure 3 In the figure, the transport unit 22 of the transport device 20 is transporting the electrode M1 in the transport direction. In addition, the stacking movable unit 12 located below the transport unit 22 is moving in the transport direction in cooperation with the transport unit 22. On the other hand, the operating movable unit 13 is stopped on the downstream side in the transport direction. The stacking movable unit 12 is in a state just before contacting the operating movable unit 13. At this time, the electrode holding unit 123 is in a holding state of holding the plurality of electrodes M1 that have been received from above.

[0048] The first rod 125 of the driving mechanism 124 has a follower at a position in contact with the first cam 133 of the operating portion 132. The follower is in contact with the first cam 133 and is driven. The follower of the first rod 125 is operated by the first cam 133, and the first rod 125 drives the electrode holding portion 123. In addition, the second rod 126 of the driving mechanism 124 has a follower in contact with the second cam 134 of the operating portion 132. The electrode holding portion 123 has a structure that switches between a holding state in which the electrode M1 is pressed from above and an open state in which a new electrode M1 can be received from above according to the action of the follower.

[0049] Figure 4 It is a second side view showing the operation of the movable portion for stacking 12 and the movable portion for operation 13 . Figure 4 The operating movable part 13 shown is Figure 3 The first lever 125 is operated by the first cam 133 to drive the electrode holding part 123 to the open state. The second lever 126 is operated by the second cam 134 to drive the electrode holding part 123 to the upwardly lifted state. Thus, the movable part 12 for laminating is in a state where it can receive a new electrode M1 from the conveying part 22.

[0050] The transport unit 22 releases the held electrode M1 and causes it to drop downward. The movable unit 12 for laminating receives a new electrode M1 and further moves in the transport direction. Then, the first lever 125 and the second lever 126 are operated by the operating unit 132, and the electrode holding unit 123 switches from the open state to the holding state.

[0051] As described above, in the electrode stacking device 1 of the present disclosure, the operating portion 132 of the operating movable portion 13 has a cam that contacts the driving mechanism 124, and the driving mechanism 124 of the stacking movable portion 12 has a follower that contacts the cam and follows. In addition, the electrode holding portion 123 has a structure that switches between a holding state in which the electrode M1 is pressed from above and an open state in which a new electrode M1 can be received from above according to the action of the follower. Thus, the electrode stacking device 1 can switch between the holding state and the open state by changing the relative position while the stacking movable portion 12 and the operating movable portion 13 are in contact.

[0052] In addition, as described above, the electrode stacking device 1 further includes the conveying device 20 .

[0053] The transport device 20 holds and transports the electrode M1 along a transport path set at least above the stator 11, and supplies the electrode M1 to the stacking movable unit 12 moving along the transport path. Thus, the electrode stacking device 1 efficiently stacks the electrodes M1.

[0054] In the electrode stacking device 1 of the present disclosure, the control unit 40 moves the stacking movable unit 12 in accordance with the conveying device 20 that conveys the electrode M1 along the conveying path. In addition, in the electrode stacking device 1, the control unit 40 controls the position of the operating movable unit 13 so that the electrode holding unit 123 is in an open state when the conveying device 20 drops the electrode M1. Thus, the electrode stacking device 1 efficiently realizes the stacking of the electrode M1.

[0055] Next, refer to Figure 5 and Figure 6 , the operations of the stacking movable portion 12 and the operating movable portion 13 will be further described. Figure 5 It is a first plan view showing the operation of the movable portion for stacking 12 and the movable portion for operation 13 . Figure 5 The positions of the stacking movable section 12 and the operating movable section 13 that change as the time T progresses are shown.

[0056] The electrode lamination device 1 shown in the upper part of the figure shows the positions of the transport unit 22, the stacking movable unit 12, and the operating movable unit 13 at time T = T11. At time T = T11, the four transport units 22 are moving in the transport direction while holding the end of the electrode M1. The four stacking movable units 12 are in a standby state along the transport direction of each of the two rails 21. In addition, the four operating movable units 13 are also on standby in the predetermined path of the movement of each of the stacking movable units 12.

[0057] Figure 5The electrode stacking device 1 shown in the middle section shows the movement of the stacking movable part 12 and the operating movable part 13 at time T=T12 after time T=T11. In addition, for easy understanding, the conveying part 22 for conveying the electrode M1 is omitted. At time T=T12, the stacking movable part 12 is moving in the conveying direction in coordination with the movement of the electrode M1. The stacking movable part 12 is in a position just before contacting the operating movable part 13. The operating movable part 13 is on standby in the predetermined path of the movement of the stacking movable part 12.

[0058] Figure 5 The electrode stacking device 1 shown in the lower section shows the operation of the stacking movable part 12 and the operating movable part 13 at time T=T13 after time T=T12. Here, the stacking movable part 12 is in contact with the operating movable part 13, and the electrode holding part 123 is in an open state. Therefore, after time T=T13, the stacking movable part 12 receives a new electrode M1 from the conveying device 20.

[0059] Next, about Figure 6 Provide explanation. Figure 6 It is a second plan view showing the operation of the movable portion for stacking 12 and the movable portion for operation 13 . Figure 6 The operation of the electrode stacking device 1 in a state where the electrode M1 is tilted about the vertical axis (about the Z axis) is shown. Figure 6 The positions of the stacking movable section 12 and the operating movable section 13 that change as the time T progresses are shown.

[0060] The electrode lamination device 1 shown in the upper part of the figure shows the positions of the transport unit 22, the stacking movable unit 12, and the operating movable unit 13 at time T = T21. At time T = T21, the four transport units 22 are holding the end of the electrode M1 and moving in the transport direction. However, Figure 6 The electrode M1 shown has an inclination of an angle θ about the vertical axis.

[0061] Figure 6The electrode stacking device 1 shown in the middle section shows the movement of the movable part 12 for stacking and the movable part 13 for operation at time T=T22 after time T=T21. At time T=T22, the movable part 12 for stacking is moving in the conveying direction in coordination with the movement of the electrode M1. At this time, the movable part 12 for stacking is in a posture with an inclination of angle θ around the vertical axis in coordination with the inclination of the electrode M1. In addition, the positions of the four movable parts 12 for stacking are also adjusted in coordination with the positions of the outer shape of the electrode M1. The movable part 12 for stacking is in a position just before it contacts the movable part 13 for operation. The movable part 13 for operation is on standby in the predetermined path of the movement of each movable part 12 for stacking. However, the movable part 13 for operation is also in a state of inclination with angle θ around the vertical axis corresponding to the posture of the movable part 12 for stacking.

[0062] Figure 5 The electrode laminating device 1 shown in the lower part of FIG. 1 shows the operation of the laminating movable part 12 and the operating movable part 13 at time T=T23 after time T=T22. The electrode holding part 123 is in the open state due to the contact between the laminating movable part 12 and the operating movable part 13.

[0063] From time T=T22 to time T=T23, the four stacking movable parts 12 move in the conveying direction while maintaining the inclination of the angle θ in accordance with the inclination of the electrode M1. At this time, the operating movable part 13 moves in the direction perpendicular to the conveying direction in accordance with the position of the stacking movable part 12. Figure 6 In the example, the operating movable part 13 moves in the positive direction of the X-axis in a manner that maintains the contact state between the follower of the driving mechanism 124 and the operating part 132 relative to the action of the stacking movable part 12 that moves in the positive direction of the Y-axis while being inclined at an angle θ around the vertical axis.

[0064] The electrode stacking device 1 can appropriately stack a new electrode M1 even if the electrode M1 is tilted by the stacking movable section 12 and the operating movable section 13 performing the above-mentioned operations. That is, the control section 40 calculates the position and tilt of the electrode M1 based on the image data, and controls the position and tilt of the stacking movable section 12 and the operating movable section 13 based on the calculation result.

[0065] As described above, in the electrode lamination device 1, the control unit 40 sets the inclination of the movable unit 12 for lamination according to the inclination of the electrode M1 around the vertical axis based on the image data obtained by photographing the posture of the electrode M1 from above the stator 11. In addition, the control unit 40 controls the displacement of the movable unit 13 for operation in the direction perpendicular to the conveying path according to the position and inclination of the movable unit 12 for lamination.

[0066] Through the above-mentioned structure, the electrode stacking device 1 can reduce the wasted area of ​​the stacked electrodes. That is, the electrode stacking device 1 suppresses the positional deviation of the newly stacked electrode M1 and efficiently stacks the sheet electrodes. In addition, according to the above-mentioned structure, the electrode stacking device 1 realizes the transportation and stacking of the sheet electrodes with a small area compared with the previous situation of using a tray to transport the sheet electrodes. Moreover, according to the above-mentioned structure, even if the size of the sheet electrode is changed, the electrode stacking device 1 can flexibly deal with the stacking process by changing the position setting of the transport unit 22 and the movable unit 12 for stacking.

[0067] As described above, the electrode stacking device 1 according to the present embodiment can suitably and continuously stack a plurality of sheet electrodes by sequentially supplying sheet electrodes to the conveyor 20. That is, according to the present embodiment, an electrode stacking device that can suitably stack sheet electrodes can be provided.

[0068] In addition, the program of the present disclosure includes a command group (or software code) for causing the computer to perform one or more functions described in the embodiment when read by the computer. The program can be stored in a non-temporary computer-readable medium or a storage medium with entity. As a non-limiting example, the computer-readable medium or the storage medium with entity includes a random access memory (RAM), a read-only memory (ROM), a flash memory, a solid-state drive (SSD) or other memory technology, a CD-ROM, a digital versatile disc (DVD), a Blu-ray (registered trademark) disk or other optical disk storage, a magnetic cassette, a magnetic tape, a magnetic disk storage or other magnetic storage device. The program can also be sent on a temporary (transient) computer-readable medium or a communication medium. As a non-limiting example, a temporary computer-readable medium or a communication medium includes a propagation signal in the form of electricity, light, sound or other forms.

[0069] The present invention is not limited to the above, and various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present invention within the scope of the invention.

[0070] From the disclosure thus described, it will be apparent that the embodiments of the disclosure may be modified in a variety of ways.
