Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a laminating apparatus for film-like parts, and more particularly to a laminating apparatus and a laminating method for stacking thin film-like parts such as battery film electrodes in a state where no air remains therebetween.
[0002]
[Prior art]
Conventionally, in order to stack a plurality of thin parts such as a film, an apparatus is used, or films are manually conveyed one by one to a predetermined stacking position and stacked.
[0003]
[Problems to be solved by the invention]
However, in the conventional apparatus, air enters between the upper and lower laminated film-like parts. In this way, the work of removing the air once entered is very troublesome. Further, if air remains between the film-like parts, there may be a significant inconvenience as a product. For example, when a film-like electrode for a battery is laminated, if air remains between the electrodes, it causes a serious defect that the battery cannot exhibit a predetermined performance.
[0004]
In addition, the film-like component is extremely light, and the resistance by the air below the film-like component is large. For this reason, when the suction is released and the film is allowed to fall naturally, the film does not fall vertically but shifts in the lateral direction, and it is difficult to neatly align the film edges after lamination.
[0005]
In addition, even if the suction tool is fully lowered and the sucked film is pressed down to release the suction, if the air is in contact with the lower film, the lowered film will float. It is often the case that the horizontal displacement occurs. In addition, depending on the film-shaped part, the sucking tool may be sufficiently lowered and pressed down, and it may be damaged. It is not preferable to press the sucking tool down.
[0006]
The present invention has been proposed in view of the above-described circumstances, and an object thereof is to provide a film-like laminating apparatus which can be laminated without air remaining between the laminated film-like parts and has few errors in the laminating position. Is.

[0012]
A laminating apparatus 1 shown in the drawing is for laminating a rectangular electrode sheet and a separator sheet used for a sheet-like battery. A rectangular frame-shaped support table 3 is provided on a frame 2 in a horizontal direction. In the support table 3, a moving tray 5 having a plurality of film-like component placement portions 4 is provided in a state in which it can move in the horizontal direction, and the pickup position in the support table 3 is set to a position away from the support table 3. A stacking position is determined, and a lift chamber 6 that moves up and down at the pickup position and the stack position is provided, and a pickup 7 that moves up and down in the lift chamber 6 is provided, and the lift chamber 6 is stacked on the pickup position and above the support table 3. A transfer mechanism 9 that reciprocates between positions is provided.
[0013]
The support table 3 is an elongated “field” -shaped frame as viewed from above. In order to form this frame body, two long materials 10 having a length of at least twice the length of the moving tray 5 and having a substantially L-shaped cross section are arranged in parallel in the longitudinal direction, and a support step portion is provided. 11 are opposed to each other inward, have a length that is at least twice the width of the movable tray 5, and have a substantially L-shaped cross-section and a short material 12 having a support step 11, so that the ends of the long material 10 are connected to each other. First, a rectangular frame is formed. Then, a short bar 13 is installed between both center portions of the long member 10 in a state where the upper surface is the same height as the support step portion 11, and the long bar 14 is interposed between both center portions of the short member 12. Is constructed in a state where the upper surface is at the same height as the support step portion 11, and is formed into an elongated “field” -shaped frame as viewed from above.
The support step portion 11 is a portion that supports the movable tray 5 in a slidable state. The lower horizontal portion abuts on and supports the lower surface of the movable tray 5, and the upright portion contacts the side surface of the movable tray 5. The position of the moving tray 5 is in contact with it, and the height of the upright portion is adjusted to the thickness of the moving tray 5.
Further, the interval between the upright portions facing each other of the long material 10 is set to twice the width of the moving tray 5, and the interval between the upstanding portions facing each other of the short material 12 is set to the moving tray 5. The length is set to twice the length.
Therefore, the support table 3 has a moving space large enough for the four moving trays 5 to enter without gaps. The three moving trays 5 are placed in the moving space, and the adjacent moving tray 5 is placed in the empty space. When the are sequentially moved, they can be moved in a square shape as a whole.
[0014]
In the present embodiment, the movement space of the support table 3 is divided into four stages (long and narrow “field” shape), the left side effort in FIG. 1 is the parts loading stage, the left back is the idle stage, and the right back is standby. The stage, the right front is the pickup stage, and the pickup position is set near the standby stage during the pickup stage.
[0015]
The moving tray 5 is a rectangular plate material in which five film-like component mounting portions 4 are arranged in a line at the same interval, and as shown in FIG. Oil-impregnated metal (dry metal) is fixed to each sliding side surface so that it can slide smoothly. It is desirable that the oil impregnated metal is also attached to the support step portion 11 of the support table on which the oil impregnated metal of the moving tray 5 slides.
The film-like component placement unit 4 is configured by laying a porous air-permeable material 16 in the upper and lower through holes 15 established in the moving tray 5, and in this embodiment, a sintered plate is laid. In the present embodiment, as shown in FIG. 3, the battery 20 has a five-layer structure in which the negative electrode 23 is laminated via the separators 22 on both sides of the positive electrode 21, so that five film-like components are placed on the moving tray 5. Although the portion 4 is provided, the number of the film-like component placement portions is not limited to this, and the design can be appropriately changed according to the number of components to be laminated. Further, the thickness of each component in the present embodiment is a film shape of several tens to 200 μm, and since these film components are rectangular, the upper and lower through holes 15 and the porous air-permeable material 16 are rectangular according to the shape of this component. It is formed. Further, a positioning guide hole 24 is opened beside each film-like component placement portion 4.
[0016]
In order to horizontally move the moving tray 5 in a square shape on the support table 3, a first end side of the support table 3 in the longitudinal direction, i.e., a side of the idle stage and the pickup stage is provided with a cylinder and a pusher. A one-tray push-out moving mechanism 25 and a second tray push-out moving mechanism 26 are provided. Further, a male screw rod 30 is provided in a state of passing through the standby stage of the support table 3 and the pickup stage, and a servo motor 31 is connected to one end of the male screw rod 30 (part of the short material 12 of the standby stage). The male screw rod 30 and the servo motor 31 and the like function as a tray moving mechanism 32 that moves the moving tray 5 to stop the film-like component mounting portion 4 at the pickup position. An engaging portion (not shown) provided is engaged with the male screw rod 30 from the side, and the rotation angle of the servo motor 31 is controlled to rotate the male screw rod 30 so that the moving tray 5 is picked up from the standby stage. Can be moved at a predetermined feed amount (pitch of the component placement unit).
[0017]
Accordingly, in the support table 3 provided with the tray moving mechanism 32 and the like, each component placement unit 4 is mechanically or manually operated by a parts loader with respect to the moving tray 5 stopped at the component loading stage. When a film-like part is placed on the movable tray 5 and the movable tray 5 is moved to the idle stage, the first tray push-out moving mechanism 26 is operated at a predetermined timing when the standby stage is vacant, and the movable tray 5 can be moved to the standby stage. In the standby stage, the tray moving mechanism 32 operates to move the moving tray 5 to the pickup stage at a predetermined pitch. Then, the film-like components on the component placement unit 4 are taken out one by one by a pickup 7 which will be described later, and when all the removal is completed, the second tray push-out moving mechanism 26 is activated to remove the empty moving tray 5. It can be moved to the part loading stage. In addition, on one moving tray 5, a plus electrode 21 is placed on the central film-like component placement unit 4, a separator 22 is placed on both sides thereof, and a minus electrode 23 is placed on the end component placement unit 4.
[0018]
The tray moving mechanism 32 is not limited to the configuration using the male screw rod 30, and may have any configuration as long as the moving tray 5 can be moved by a predetermined amount, for example, a timing belt stretched along the moving direction. The moving tray 5 may be moved by moving a predetermined amount.
[0019]
Next, a mechanism such as a pickup 7 that takes out a film-like part on the pickup stage will be described.
[0020]
First, the transfer mechanism 9 of the pickup 7 will be described. As shown in FIG. 1, a beam that passes above the pickup position and the stacking position in a state where the upright 40 is erected from the frame 2 and supported by the uprights 40. A material base 41 is installed, a cylinder 42 is attached to the beam material 41, and a moving base 43 that reciprocates between the pickup position and the stacking position by the operation of the cylinder 42 is provided. 44, and a lifting base 46 having a support leg 45 is provided in a state connected to the lower end of the rod of the chamber lifting cylinder 44, and the lifting chamber 6 is attached to the lower end of the support leg 45.
[0021]
The elevating chamber 6 is a metal box having an open bottom surface, and an opening edge is formed in a size and a shape that can cover the film-like component mounting portion 4 from above. The height is high enough to move up and down. An intake pipe 50 that constitutes a part of the chamber decompression mechanism is connected to the side surface of the lift chamber 6, and a pickup lift cylinder 51 is attached to substantially the center of the upper surface, and an intake pipe through hole is provided in the vicinity of the cylinder 51. The guide post through hole is opened on the left and right of the upper surface. A sealing material 52 is provided on the entire lower surface of the opening edge of the elevating chamber 6.
[0022]
As shown in FIG. 2, the pickup 7 is a rectangular hollow box-like body, and an internal hollow portion functions as a suction chamber, and a small suction hole 53 is formed on almost the entire surface of the lower surface of the box-like body. Further, the pickup 7 supports and supports the tip of the rod of the pickup lifting / lowering cylinder 51 at substantially the center of the upper surface, and guide posts 54 are erected on the left and right of the upper surface to guide the lifting / lowering chamber 6. An intake pipe 55 that constitutes a part of the pickup pressure reducing mechanism is connected in the vicinity of the portion that penetrates into the through hole and fixes the rod.
Since the lower surface of the pickup 7 is treated with a fluororesin or the like, even if the separator 22 is wet with the electrolytic solution, if the suction from the suction hole 53 is stopped, it is surely peeled off due to its own weight.
[0023]
Next, the configuration of the stacking position will be described.
This stacking position is set outside the support table 3 and in the vicinity of the pickup position. Then, as shown in the right side portion in FIG. 2, similarly to the component mounting portion 4, upper and lower through holes are opened in the plate material 60, and a sintered plate is laid as a porous air-permeable material 61 in the through holes, An intake pipe 63 constituting a part of the stacking position decompression mechanism is connected to the decompression chamber 62 formed below the breathable member 61.
[0024]
The chamber decompression mechanism, the pickup decompression mechanism, the stacking position decompression mechanism, and the like may be independent vacuum pumps. However, in this embodiment, a vacuum pump 64 is provided at the lower portion of the frame 2 and the vacuum pump is provided. The pump 64 is provided with a vacuum storage tank 65 that is depressurized by suction, and a pipe branched from the tank 65 is connected to a predetermined part as an intake pipe. In order to return to atmospheric pressure after decompression, an air release valve is provided in the middle of each intake pipe so that it can be opened in a state where communication with the vacuum storage tank 65 is blocked at a predetermined timing.
[0025]
Next, in the laminating apparatus 1 having the above-described configuration, a procedure for sequentially laminating a film-like component taken out at the pickup position and then transported to the laminating position will be described.
[0026]
When the moving tray 5 is moved by the operation of the tray moving mechanism 32 and the component placement unit 4 on which the film-like component is placed stops at the pickup position, the elevator chamber 6 coming above the pickup position is lowered. A positioning pin 66 projecting downward from the flange portion of the lifting / lowering chamber 6 is inserted into the positioning guide hole 24 of the moving tray 5 so that the positions of the component mounting portion 4 and the lifting / lowering chamber 6 are securely aligned, and a sealing material 52 is pressed against the upper surface of the moving tray 5.
[0027]
When the elevating chamber 6 is lowered in this way to cover the component placement section 4, the pickup elevating cylinder 51 is operated to lower the pickup 7 and apply the lower surface to the upper surface of the film-like component. Then, the pickup depressurization mechanism is operated to suck air from the suction hole 53 on the lower surface of the pickup 7 and depressurize the upper surface of the film-like component. Then, since the film-like component is placed on the porous air-permeable material 16, air that has passed through the porous air-permeable material 16 freely enters the lower surface of the film-like component. Accordingly, the film-like component is adsorbed on the lower surface of the pickup 7 (the pickup Process ).
Since the suction hole 53 is opened on one surface of the lower surface of the pickup 7, even a thin part such as a film part can be uniformly adsorbed without causing partial slack.
[0028]
If the film-like component is adsorbed on the lower surface of the pickup 7, the pickup 7 is raised by the operation of the pickup raising / lowering cylinder 51 while the operation of the pickup decompression mechanism is continued, and the raising / lowering chamber 6 is moved by the chamber raising / lowering cylinder 44. Raise.
[0029]
When a film-like component is picked up by the pickup 7, the tray moving mechanism 32 is actuated to feed the moving tray 5 by a predetermined amount (one pitch of the component mounting portion 4), and the next component mounting portion 4 is aligned with the pickup position. Stop. Since the tray moving mechanism 32 repeats such an operation, the component mounting portion 4 on which the film-like component is placed can be sequentially stopped at the pickup position, and all the film-like components in the moving tray 5 can be stopped. Is picked up, the second tray push-out moving mechanism 26 pushes the moving tray 5 from the pick-up stage to the component loading stage to empty the pick-up stage. Since the first tray push-out moving mechanism 25 pushes the next moving tray 5 into the standby stage, the moving tray 5 can be moved in accordance with the timing of the pickup 7 and the like as described above.
[0030]
On the other hand, the lifting chamber 6 and the pickup 7 that are lifted while adsorbing the film-like parts move the moving base 43 from above the pickup position to above the stacking position by the operation of the transfer mechanism 9, and this transfer process is completed. When reaching above the stacking position, the chamber lifting / lowering cylinder 44 operates first to lower the lifting / lowering chamber 6.
[0031]
When the elevating chamber 6 is lowered, the positioning pin 66 is inserted into the positioning guide hole 67 provided in the plate material 60 at the stacking position, and the positional relationship between the lifting chamber 6 and the stacking position is reliably matched, and the sealing material 52 is used. Is pressed against the upper surface of the plate member 60 to seal the inside of the elevating chamber 6. In this way, the elevating chamber 6 is lowered and the porous air-permeable material at the stacking position. 61 If the cover is covered, the pickup cylinder 51 is actuated to lower the pickup 7, and the film-like component adsorbed on the lower surface is removed from the porous air-permeable material. 61 Near or lightly contact the top surface of
[0032]
Then, the chamber decompression mechanism is operated to decompress the inside of the ascending / descending chamber 6 and the stacking position decompression mechanism is operated to decompress the upper surface of the porous air-permeable material 61 at the stacking position. Thus, when the pressure in the pickup 7 and the elevating chamber 6 is reduced, the air becomes lean, and the porous air-permeable material 61 Due to the pressure difference between the upper surface of the film and the air pressure acting on the upper surface of the film-shaped component, the film-shaped component separates from the lower surface of the pickup 7 and falls onto the porous air-permeable material 61 at the stacking position (component lowering step). Therefore, when this part lowering process is completed, the first film-like part is accurately placed at a predetermined position of the stacking position. Even if the first film-like component is placed on the porous air-permeable material 61 at the stacking position, the entire surface is covered because the porous air-permeable material 61 is slightly larger than the film-like component. However, since the outer peripheral edge remains, the suction action can be continued through the porous air-permeable material 61.
[0033]
In this way, when the first film-like part (minus electrode 23) is lowered onto the porous air-permeable material 16 at the stacking position, the inside of the ascending / descending chamber 6 and the inside of the pickup 7 are returned to atmospheric pressure, and then the pickup 7 And the elevating chamber 6 is raised. Then, the elevated lift chamber 6 and the like are again transferred to the pickup position by the operation of the transfer mechanism 9, and by repeating the same operation as described above, the second film-like part is adsorbed and then returned to the stacking position. come.
[0034]
The returning lifting chamber 6 is lowered onto the plate material 60 at the stacking position by the operation of the chamber lifting cylinder 44 and the sealing material 52 is sealed, and the pickup 7 is also lowered and adsorbed in the same manner as described above. The film-like component (separator 22) is brought into close contact or light contact with the film-like component (minus electrode 23) already placed. In this state, as described above, the chamber decompression mechanism is operated to decompress the inside of the ascending / descending chamber 6, and the stacking position decompression mechanism is operated to decompress the porous air-permeable material 61 at the stacking position. As described above, when the pressure in the pickup 7 and the lift chamber 6 is reduced, the air becomes lean, and the air pressure acting on the outer peripheral portion of the upper surface of the porous air-permeable material 61 and the upper surface of the conveyed film-like component The film-like component is detached from the lower surface of the pickup 7 due to the pressure difference and is laminated on the first film-like component already placed at the lamination position (component descending step).
[0035]
Therefore, the second film-like component is also accurately laminated on the first film-like component at a predetermined position of the lamination position. Note that the air between the two film-like parts almost disappears in the laminated state because the outer peripheral edge portion of the porous air-permeable material 61 is at a negative pressure. The suction chamber 61 and the pickup 7 are first returned to the atmospheric pressure while being sucked from the property material 61, and then the suction of the porous air-permeable material 61 is stopped and returned to the atmospheric pressure. End up.
[0036]
When the above-mentioned operation is repeated to laminate the predetermined five film-like parts at the laminating position and the laminating process is completed, the laminated parts are taken out by the moving means such as the taking-out arm 70 and the like, and the belt conveyor 71 etc. It is placed on the transport mechanism and sent to the next assembly process.
[0037]
The first embodiment described above is configured to move the chamber 6 up and down and move between the pickup position and the stacking position. However, the present invention is not limited to this, and the lower surface is opened. Pickup having a chamber 6, a chamber pressure-reducing mechanism for depressurizing the inside of the chamber 6, and a vacuum chamber that can be moved up and down inside the chamber 6, has a suction hole 53 on a substantially lower surface, and communicates with the suction hole 53. 7, a pickup pressure reducing mechanism for reducing the pressure in the suction chamber of the pickup 7, a porous air permeable material 61 laid at the stacking position, and a layer for connecting the porous air permeable material 61 to reduce the upper surface of the porous air permeable material 61. And a position decompression mechanism.
[0038]
In this case, for example, as in the first embodiment, the porous air-permeable material 16 on which a film-like component is placed is conveyed below the pickup 7 and then the porous air-permeable material 16 is raised to open the lower surface of the chamber 6. In this state, the pickup 7 is lowered to adsorb the film-like component on the porous air-permeable material 16, and the evacuated porous air-permeable material 16 is taken out from below the chamber 6. Next, the stacking position where the porous air-permeable material 61 is laid is moved below the chamber 6, the stacking position is raised and matched with the lower surface opening of the chamber 6, and then the pickup 7 is lowered to the stacking position. In the same manner as in the first embodiment, the porous air-permeable material 61 in the chamber 6 and the laminated position is depressurized, and the film-like parts are laminated due to the difference in pressure between the pickup, the chamber, and the porous air-permeable material at the laminated position. Lower to position. By repeating the above operation, a plurality of film-like parts are laminated at the lamination position. Even if laminated in this way, air does not enter between the laminated film-like parts.
If the chamber 6 is configured to be movable up and down, it is not necessary to move up and down the stacking position where the porous air-permeable material 16 or the porous air-permeable material 61 on which the film-like component is placed is laid.
In short, the film-like component is adsorbed on the lower surface while the inside of the pickup 7 is decompressed, the inside of the chamber 6 surrounding the pickup 7 is decompressed, and the porous air-permeable material 61 at the stacking position located below the pickup 7 is decompressed. If the structure to be provided is provided, a plurality of film-like parts can be sequentially laminated in a state in which no air enters.
[0039]
Further, in the first embodiment, five film component mounting parts 4 are provided on one moving tray 5, but the moving tray may be divided for each film component mounting part 4. With this configuration, it is possible to easily cope with specifications having different numbers of components to be stacked, and it is possible to reduce operation loss due to specification changes.
[0040]
The present invention is not limited to the case of laminating the above-described film-like electrodes, and can be used for the work of laminating thin film-like or sheet-like parts.
[0041]
【The invention's effect】
As described above, the present invention has the following effects.
According to the first aspect of the present invention, the chamber having the lower surface opened, the chamber pressure-reducing mechanism for depressurizing the inside of the chamber, and the inside of the chamber can be moved up and down. A pickup having a connected suction chamber, a pickup pressure-reducing mechanism that depressurizes the suction chamber of the pickup, a porous air-permeable material laid at the stacking position, and the upper surface of the porous air-permeable material is decompressed by being connected to the porous air-permeable material And a stacking position decompression mechanism, so that when the film-like component is placed, the film-like component is caused by the difference between the pressure of the pickup that adsorbs the film-like component and the pressure acting on the lower surface of the film-like component. Can be detached from the lower surface of the pickup. And since it laminates while sucking the air between the film-like part to be removed from the pickup in this way and the previous film-like part located below it, the film-like part is laminated in a state where air is evacuated. can do.
[0042]
According to the second aspect of the present invention, the film-like component is placed on the film-like component mounting portion laid with the porous air-permeable material, and the film-like component is adsorbed on the lower surface of the pickup having the suction hole substantially on one surface. Therefore, almost the entire area of the film-like part can be lifted uniformly. And at the lamination position, the lamination position is covered by the elevating chamber, the inside is made negative pressure, and the porous breathable material laid at the lamination position can be depressurized. It is possible to prevent air from remaining between the film-like parts.
[0043]
In addition, since the layers are laminated while venting the air between the film-like parts to be laminated, the film-like parts detached from the lower surface of the pickup are not subjected to a large air resistance and can be prevented from floating even if they are lowered. The respective positions of the film-like parts thus made can be accurately aligned, and irregularities can be eliminated.
[0044]
According to the invention of claim 3, a plurality of film-like component placement portions are arranged side by side, a movable tray in which a porous air-permeable material is laid on each film-like component placement portion, and a state in which this movable tray can be moved in the horizontal direction And a tray moving mechanism that moves the moving tray and stops the film-like component placement portion at the pickup position, so that the position of the component to be picked up can be accurately adjusted. Therefore, the position error after laminating the picked up film-like parts can be further reduced.
[0045]
According to the invention of claim 4, a pickup process is provided in the elevating chamber having the lower surface opened, and the film-like component is adsorbed on the lower surface of the pickup by being sucked from an intake hole provided on substantially one surface of the lower surface. The pickup process that picks up the parts and the lifting chamber is moved above the stacking position, the lifting chamber is lowered, the stacking position where the porous air-permeable material is laid is covered from above by the lifting chamber, and the pickup is lowered. Then, the pressure in the lower surface of the film-like component is reduced compared to the pressure on the upper surface of the film-like component by reducing the pressure in the elevating chamber and sucking air through the porous air permeable material. Laminating by repeating the part lowering process that lowers the part by removing it from the lower surface of the pickup Since stacking a plurality of film-like component to location, it is possible to prevent air from remaining between the stacked film-like component.
