A step of forming a circuit, and a step of sealing with a protective sheet and attaching an external terminal.

  Conventionally, soldering has been widely used as a method for connecting a wiring member to a cell. Lead-containing solder is a good conductor and has a certain strength and environmental reliability. However, from the viewpoint of environmental protection in recent years, it has been considered to use lead-free solder, and when this lead-free solder is used, a decrease in reliability due to a difference in thermal expansion has been a problem.

Therefore, there is known a method for avoiding a decrease in reliability due to a difference in thermal expansion by connecting a wire and a cell using a conductive film or an anisotropic conductive film (ACF) (patent) Reference 1).
On the other hand, since anisotropic conductive films are expensive, an anisotropic conductive film is not provided over the entire length of the thin-film solar cell wiring length with low current density, but is anisotropic by a method of providing wiring in various places (single piece attachment) A method for reducing the amount of conductive film used has been proposed (see Patent Document 2).

In order to help understanding at that time, typical crystalline solar cells (hereinafter simply referred to as “ The structure of the cell string 4) will be described with reference to FIG.

[Cell string]
The cell 1 shown in FIG. 14 has electrode patterns 1a (see FIG. 7) on the front and back. Four wires 2 are attached to the front and back of the cell 1. The attachment of the four electric wires to the front and back of each cell 1 is performed by attaching a conductive film (not shown) to several places (for example, six places) of each electric wire 2.

  The cell string 4 is configured by connecting, for example, ten cells 1 by electric wires 2. The solar cell module includes a plurality of cell strings 4, a transmissive glass and a back sheet that sandwich the plurality of cell strings 4.

  The cell string 4 shown in FIG. 14 is configured by connecting cells 1 using four electric wires. The number of cells 1, the number of electric wires 2, the number and length of conductive films are as follows. This should be determined by the design of the battery module. In other words, in the cell string according to the present invention, it is of course possible to freely change the number of the electric wires 2 or to separately determine the connection location on the front and back sides.

1. First Embodiment [Solar Cell Module Assembly Device]
Next, a solar cell module assembling apparatus will be described with reference to FIG.
FIG. 1 is a plan view showing the overall configuration of an embodiment of a solar cell module assembling apparatus (hereinafter referred to as “this example”).

  In the solar cell module assembling apparatus 100 of the present example, an electric wire supply unit 101, an electric wire straightening unit 102, and an electric wire cutting unit 104 are arranged in order from the left side in the lower part of FIG. In addition, a cell supply unit 105, a conductive film sticking unit 103, and a separator peeling device 106 are arranged in the upper part of FIG.

  Further, on the right side (rear) of the lower stage of FIG. 1, a preheating and provisional pressure bonding unit 107 that joins and preheats the electric wire 2 to the cell 1, a main crimping unit 108 that crimps the cell 1 and the electric wire 2, and a final pressure bonding are provided. A cooling unit 109 for cooling the cell 1 is arranged. Next to the cooling unit 109, a transfer device 110 is arranged for pulling out the cell strings 4 (see FIG. 14) connected in a chain form from the cooling unit 109 and delivering them to the next step 120.

  In the solar cell module assembling apparatus 100 configured as described above, first, an electric wire (not shown) is supplied from the electric wire supply unit 101, and the distortion generated during the electric wire transportation is corrected by the electric wire correction unit 102. That is, since the flat electric wire sent from the electric wire supply unit 101 is wound around a reel (not shown), for example, it has a restoring force that deforms so as to be bent. Therefore, the electric wire straightening unit 102 has a mechanism for forcibly removing the curl generated in the flat electric wire by this restoring force.

  In FIG. 1, the specific configuration of the electric wire straightening unit 102 is not shown, but in the electric wire straightening unit 102, for example, a dancer roller is disposed between two supplied feed rollers against bending of the electric wire, Appropriate tension is applied to the wires against the restoring force of the wires. That is, the electric wire correction unit 102 corrects curl generated on the electric wire while maintaining this tension.

  The electric wire whose curl has been corrected by the electric wire correction unit 102 is sent to the electric wire cutting unit 104. The wire cutting unit 104 cuts the wire into a length that is an integral multiple of the cell length (here, approximately twice). In the electric wire cutting unit 104, the tip of the electric wire drawn into the unit is received by a chuck, and the electric wire is cut from above and below by a cutting blade (not shown).

  On the other hand, the cell 1 (see FIG. 8) is supplied from the cell supply unit 105 in a state of being stacked on the tray, and is conveyed to the conductive film pasting unit 103. The conductive film pasting unit 103 collects a plurality of pieces of conductive film (hereinafter referred to as “conductive film” including these small pieces) separated in a plurality at a predetermined location of the supplied cell 1. And paste.

  The conductive film has a conductive layer having adhesiveness and conductivity, and a separator (release paper) superimposed on one surface of the conductive layer, and the cell is in a state where the conductive layer and the separator are adhered. 1 is pasted. Thereafter, the cell 1 to which the conductive film is attached is sent to the separator peeling device 106. The separator peeling device 106 peels only the separator from the conductive film attached to the cell 1.

  The cell 1 from which the separator of the conductive film has been removed is sent to the preheating and provisional pressure bonding unit 107 in that state. In the preheating and provisional pressure bonding unit 107, the cell 1 sent from the separator peeling device 106 and the electric wire 2 cut by the electric wire cutting unit 104 are joined and preheated and provisional pressure bonded.

  In the main crimping unit 108, thermocompression bonding is performed in a state where the electric wire 2 and the cell 1 are integrated, and the chained cell string 4 (see FIG. 14) is sequentially drawn out to the cooling unit 109. Thereafter, the cell string 4 is delivered to the next step 120 by the transfer device 110.

Next, the cell supply unit 105 and the conductive film sticking unit 103 will be described with reference to FIG.
FIG. 2 is a front view for explaining the process of attaching the conductive film to the cell 1.

  As shown in FIG. 2, the cell supply unit 105 includes a cell tray 151 in which a plurality of cells 1 are stacked, an elevator 152, a suction head 153, and a transfer mechanism 154.

  The cell tray 151 is maintained by the elevator 152 so that the height of the surface of the uppermost cell 1 is constant. That is, the uppermost cell 1 is adsorbed by the adsorption head 153 and conveyed to the conductive film pasting unit 103 one by one by the transfer mechanism 154. At this time, when the uppermost cell 1 is carried by the transfer mechanism 154, the elevator 152 rises. Thereby, the height of the surface of the uppermost cell 1 in the cell tray 151 is controlled to be always constant.

  The conductive film sticking unit 103 is configured to move the feed roller 131 that feeds the tape-like conductive film 3, the conductive film sticking head 133 that sticks the conductive film to the cell 1, and the conductive film sticking head 133. Drive mechanism 134 is provided. These specific operations will be described later with reference to FIGS.

Next, the process of attaching the conductive film 3 to the cell 1 in the conductive film attaching unit 103 will be described with reference to FIGS.
FIG. 3 is a perspective view showing the conductive film sticking head 133 and its peripheral members in the conductive film sticking unit 103.

  As shown in FIG. 3A, the conductive film 3 is transported by a predetermined length by the feed roller 131 and inserted between the eight cutter blades 138b and the saddle plate 138a. At this stage, the saddle plate 138a is lowered by a drive mechanism (not shown), and the conductive film 3 is half-cut by the cutter blade 138b.

  Here, the half cut is a state in which only the conductive layer 3b of the conductive film 3 is cut and the separator (release paper) 3a is not cut by sandwiching the conductive film 3 between the cutter blade 138b and the gutter 138a. Say. The rib plate 138a is provided with irregularities (see FIG. 4) at the contact portion of the cutter blade 138b. Therefore, the conductive film 3 is half cut in a perforated shape.

  Thereafter, as shown in FIG. 3B, the gutter 138a is retracted upward, and the cutter blade 138b holds the conductive film 3 in a half-cut state and transfers it to the lower part of the conductive film sticking head 133. Then, the conductive film sticking head 133 is lowered by a drive mechanism (not shown), and the conductive film 3 is divided into eight small pieces by the conductive film sticking head 133 and the cutter blade 138b. The dividing operation will be described in detail with reference to FIG.

FIG. 4 is an explanatory diagram for explaining a process of cutting the conductive film 3 before being attached to the cell 1.
In FIG. 4, the example which affixes the electroconductive film 3 on the surface and the back surface of the cell 1 is shown. For this reason, two conductive mechanisms 3, cutter blades 138b, conductive film sticking head 133, and driving mechanism 134 of conductive film sticking head 133 (hereinafter simply referred to as “driving mechanism 134”) are shown.

  In the state shown in FIG. 4, the cutter blade 138b is disposed between the conductive film sticking heads 133 disposed above and below. That is, the cell 1 (see FIG. 6) has not been inserted between the conductive film sticking heads 133 yet.

  The conductive film sticking head 133 is formed in an elongated bar shape. A vacuum suction hole (not shown) is provided at the tip of the conductive film sticking head 133, and the conductive film 3 can be sucked by sucking air from the vacuum suction hole. Yes. In this example, eight conductive film sticking heads 133 are provided.

  The driving mechanism 134 includes a sliding member 134a, a guide rail 134b, a driving member 134c, and a guide member 134d. The sliding member 134a is connected to each of the eight conductive film sticking heads 133, and the guide rail 134b guides the sliding member 134a in the horizontal axis direction. The drive member 134c moves the sliding member 134a along the guide rail 134b, and the guide member 134d guides the drive member 134c.

  The cutter blade 138b is fixed to a pedestal 138d, and the pedestal 138d moves up and down by an elevating mechanism 138c. As the pedestal 138d moves up and down, the eight cutter blades 138b are inserted between each of the eight conductive film application heads 133 that are also provided, and cut the conductive film 3.

  In this example, a rotating cam is used as an elevating mechanism 138c that elevates and lowers the cutter blade 138b via a base 138d. However, as the mechanism for raising and lowering the cutter blade according to the present invention, it is possible to apply a mechanism that can move the pedestal up and down, such as a cylinder mechanism, in addition to the cam. Hereinafter, the lifting mechanism 138c will be described as the cam mechanism 138c.

Next, the cutting | disconnection operation | movement of the conductive film 3 by the conductive film sticking unit 103 is demonstrated.
As shown in FIG. 4, the half-cut conductive film 3 is held between the cutter blades 138 b and transferred between the two conductive film sticking heads 133.

Next, the upper conductive film sticking head 133 is lowered, and the lower conductive film sticking head 133 is raised to suck the separator 3a side of the conductive film 3 by suction from the vacuum suction hole described above.
Subsequently, the cam mechanism 138c rotates and pushes the cutter blade 138b into the upper and lower conductive film application head 133 sides via the base 138d. As a result, the half-cut conductive film 3 is completely cut by the cutter blade 138b.

  In FIG. 4, the upper conductive film 3 is cut, but the lower conductive film 3 remains in a half-cut state. As described above, the cutting of the conductive film 3 by the cutter blade 138b can be performed separately vertically, that is, at different times. However, it is usually preferable to simultaneously cut the conductive films 3 disposed above and below by one rotation of the cam mechanism 138c.

Next, the operation until the cut conductive film 3 is attached to the cell 1 will be described with reference to FIG.
FIG. 5 is an explanatory diagram for explaining a process of attaching the conductive film 3 to the specified positions of the front surface and the back surface of the cell 1.

  As shown in FIG. 5, each conductive film sticking head 133 is spread substantially uniformly over the entire width of the cell 1 by the cooperative operation of the driving member 134 c and the sliding member 134 a in the driving mechanism 134.

  As described above, a vacuum suction hole (not shown) is provided at the tip of each conductive film sticking head 133. And the separator 3a side of the electroconductive film 3 is attracted | sucked with the attraction | suction force from a vacuum suction hole. And the cell 1 is conveyed between the electroconductive film sticking heads 133 which oppose up and down.

  Next, the drive mechanism 134 moves up and down, and each conductive film sticking head 133 presses the conductive layer 3 b of the conductive film 3 against the front and back surfaces of the cell 1. Thereby, the electroconductive film 3 is affixed on the position where the surface of the cell 1 and the back surface were prescribed | regulated. In addition, the specified position on the cell 1 where the conductive film 3 is attached is a position where the electric wire 2 is overlapped in the preheating and provisional pressure bonding unit 107 (see FIG. 1).

  Subsequently, the suction from the vacuum suction holes of each conductive film sticking head 133 is stopped, the drive mechanism 134 is moved up and down, and each conductive film sticking head 133 is pulled away from the cell 1. Thereby, the attachment to the cell 1 of the electroconductive film 3 which has the separator 3a and the conductive layer 3b is completed. The cell 1 to which the conductive film 3 is attached is sent to the separator peeling device 106 (see FIG. 1).

  When the conductive film 3 is attached to the cell 1, the cutter blade 138b attached to the base 138d is retracted together with the cam mechanism 138c to the position of the cover plate 138a. Then, the conductive film 3 to be half-cut next is inserted between the gutter 138a and the cutter blade 138b.

  In the conductive film sticking unit 103, the conductive film 3 attached to the cell 1 is in a state where the separator 3a is attached to the conductive layer 3b. Therefore, it is necessary to remove the separator 3a from the conductive film 3 before joining the cell 1 and the electric wire 2 (temporary pressure bonding).

[Separator peeling device]
Next, the configuration of the separator peeling device 106 will be described with reference to FIG.
FIG. 6 is a front view of the separator peeling device 106 showing the first embodiment of the separator peeling device.

  As shown in FIG. 6, the separator peeling device 106 includes a peeling block 161 that faces the supplied cell 1 and a holding member 162 that holds the peeling block 161. Furthermore, a cylinder 163 that moves the holding member 162 in the vertical direction and a support member 164 that supports the cylinder 163 are provided.

  In this example, in order to attach the conductive film 3 to the front and back surfaces of the cell 1, the conductive layer 3 b of the conductive film 3 attached to the front surface of the cell 1 and the conductive material attached to the back surface of the cell 1. It is necessary to peel the separator 3a from the conductive layer 3b of the film 3, respectively. Therefore, the separator peeling device 106 of this example is provided with two peeling blocks 161, holding members 162, and two cylinders 163. The support member 164 is configured to support the two cylinders 163.

The peeling block 161 includes a base portion 165, a peeling portion 166, a roller 167, and a suction portion 168.
The base portion 165 is formed in a substantially rectangular parallelepiped shape, and has a cell facing surface 165a facing the cell 1 and a back surface 165b which is a surface opposite to the cell facing surface 165a. A biasing member 169 described later is fixed to the back surface 165b of the base portion 165.

  The peeling portion 166 is fixed to the base portion 165 by a fixing method such as a screw or welding, and has a contact claw 166a that slightly protrudes from the cell facing surface 165a. The contact claw 166a contacts the separator 3a of the conductive film 3 attached to the cell 1, and peels the separator 3a from the conductive layer 3b. In addition, the base portion 165 is provided with an adjustment portion (not shown) that adjusts the protruding amount of the contact claw 166a with respect to the cell facing surface 165a by changing the attachment position of the peeling portion 166.

  The number of peeling portions 166 is appropriately determined according to the number of small pieces of the conductive film 3 to be attached to the cell 1. For example, when the separator 3a in each small piece of the conductive film 3 is peeled in one operation, the same number of peeling portions 166 as the small pieces in the conductive film 3 may be provided. Moreover, you may make the peeling part which concerns on this invention into the shape which peels the 2 or more separator 3a simultaneously.

  At least two rollers 167 are provided for one base portion 165, and are rotatably attached to the base portion 165. At least a part of the roller 167 protrudes from the cell facing surface 165a and comes into contact with the front or back surface of the cell 1 or the electrode pattern 1a on the front or back surface. The rotation axis of the roller 167 is parallel to the cell facing surface 165a and parallel to the direction orthogonal to the transport direction X1 of the cell 1.

  The suction part 168 shows one specific example of the recovery part according to the present invention, and recovers the separator 3a peeled off from the conductive layer 3b. The suction unit 168 includes a nozzle 168a and a negative pressure generation unit (not shown) connected to the nozzle 168a. The tip of the nozzle 168a is disposed on the side of the peeling portion 166 and is exposed from the cell facing surface 165a.

The holding member 162 includes a holding portion 162a that holds the side portion of the base portion 165 in the peeling block 161, and a cylinder connecting portion 162b that is continuous with the holding portion 162a.
The holding part 162a holds the peeling block 161 so as to be movable in the vertical direction. The cylinder connecting portion 162b faces the back surface 165b of the base portion 165 in the peeling block 161.

  A biasing member 169 that biases the peeling block 161 toward the cell 1 is provided between the peeling block 161 disposed on the upper side with respect to the cell 1 and the holding member 162 that holds the peeling block 161. Yes.

In this example, a compression coil spring is applied as the biasing member 169. One end of the biasing member is connected to the back surface 165b of the base portion 165 in the peeling block 161, and the other end is connected to the cylinder connecting portion 162b of the holding member 162.
The urging member according to the present invention is not limited to a compression coil spring, and a spring member such as a leaf spring or a disc spring, a rubber member, or the like can also be applied.

  Further, an adjustment screw 170 is provided between the peeling block 161 disposed below the cell 1 and the holding member 162 that holds the peeling block 161. The adjustment screw 170 is used, for example, to adjust the height of the peeling block 161 disposed below the cell 1 and the level of the cell facing surface 165a of the peeling block 161.

  In addition, as a separator peeling apparatus of this invention, the structure which provides a biasing member instead of the adjustment screw 170 may be sufficient. That is, an urging member may be provided between the peeling block 161 disposed below the cell 1 and the holding member 162 that holds the peeling block 161.

  The cylinder 163 shows a specific example of the elevating part according to the present invention, and moves the peeling block 161 up and down via the holding member 162. The vertical direction is a direction in which the two peeling blocks 161 are opposed to each other, and is a direction orthogonal to the front surface and the back surface of the cell 1.

  When the cylinder 163 moves the peeling block 161 toward the cell 1 via the holding member 162, the roller 167 of each peeling block 161 comes into contact with the front surface or the back surface of the cell 1. Since the upper peeling block 161 is urged toward the cell 1 by the urging force of the urging member 169, the roller 167 of each peeling block 161 is always in contact with the front or back surface of the cell 1. Thereby, the distance (height) from the front surface or back surface of the cell 1 to the peeling portion 166 is defined. That is, the roller 167 and the biasing member 169 constitute a distance defining mechanism according to the present invention.

  The support member 164 includes an upper support portion 164a that supports the upper cylinder 163, a lower support portion 164b that supports the lower cylinder 163, and a connecting portion 164c that connects the upper support portion 164a and the lower support portion 164b. ing. The support member 164 is supported by a horizontal movement mechanism 171 (see FIG. 2) so as to be movable in a direction parallel to the transport direction X1 of the cell 1 and a direction orthogonal to the transport direction X1 of the cell 1.

  When the support member 164 moves in the processing direction X2 opposite to the conveyance direction X1 of the cell 1, the peeling portion 166 of the peeling block 161 is moved from the side of the conductive film 3 attached to the cell 1 to the separator 3a. Contact.

[Operation of separator peeling device]
Next, the operation of the separator peeling device 106 will be described with reference to FIG.
FIG. 7 is an explanatory diagram for explaining the operation of the separator peeling device 106.

  In the separator peeling device 106, the upper peeling block 161 and the lower peeling block 161 (see FIG. 6) are opposite in operation in the vertical direction, and the other operations are the same. Therefore, in FIG. 7, the lower peeling block 161 of the cell 1 is omitted, and the operation of the upper peeling block 161 will be described as an example.

The cell 1 to which the conductive film 3 is affixed is conveyed between the peeling blocks 161 and arranged at the processing position.
When the cell 1 is disposed at the processing position, the cylinder 163 (see FIG. 6) operates to move the peeling block 161 in the vertical direction (cell 1 side). Thereby, the roller 167 of the peeling block 161 contacts the surface of the cell 1 (refer FIG. 7A).

  At this time, since the upper peeling block 161 is always urged toward the cell 1 by the urging member 169, the height from the surface of the cell 1 to the peeling portion 166 in the upper peeling block 161 is always defined. It becomes constant. In addition, since the lower peeling block 161 (not shown) sandwiches the cell 1 with the upper peeling block 161, the height from the back surface of the cell 1 to the peeling portion 166 in the lower peeling block 161 is defined. Always constant.

As a result, even if the thickness of the cells 1 that are sequentially conveyed varies, the contact claw 166a of the peeling portion 166 can be reliably opposed to the side of the separator 3a in the conductive film 3. Thereby, the peeling part 166 can be made to contact the separator 3a of the electroconductive film 3 reliably, and the peeling leak of the separator 3a can be prevented or suppressed.
Furthermore, the contact between the contact claw 166a of the peeling portion 166 and the conductive layer 3b of the conductive film 3 can be suppressed, and the conductive layer 3b can be prevented from being damaged by the contact claw 166a.

  The peeling block 161 is provided with an adjustment unit (not shown) that adjusts the protruding amount of the contact claw 166a with respect to the cell facing surface 165a. Accordingly, when using conductive films of different types and different thicknesses of the conductive layer, the amount of protrusion of the contact claw 166a with respect to the cell facing surface 165a is changed by an adjustment unit (not shown). Thereby, the contact nail | claw 166a can be made to oppose the side part of the separator in the conductive film from which a kind differs.

  When the roller 167 of the peeling block 161 comes into contact with the surface of the cell 1, a negative pressure generating unit (not shown) of the suction unit 168 is driven, and vacuum suction by the suction unit 168 is started. The vacuum suction by the suction unit 168 may be started before the peeling block 161 is moved to the cell 1 side, for example.

  Next, the horizontal movement mechanism 171 operates to move the peeling block 161 in the processing direction X2 (see FIG. 7B). Thereby, the contact nail | claw 166a of the peeling part 166 contacts the separator 3a from the side of the electroconductive film 3, and peels a part of separator 3a from the conductive layer 3b.

  When a part of the separator 3a is peeled from the conductive layer 3b by the contact claw 166a, the cylinder 163 (see FIG. 6) operates to raise the peeling block 161 (see FIG. 7C). At this time, when the peeling block 161 is moved also in the processing direction X2 by the operation of the horizontal movement mechanism 171 (see FIG. 2), the peeling block 161 moves obliquely upward.

  When the peeling block 161 is raised, the contact claw 166a of the peeling portion 166 is separated from the conductive layer 3b. The separator 3a partially peeled off from the conductive layer 3b is peeled off from the conductive layer 3b by being sucked by the suction portion 168.

  That is, in the separator peeling device 106 of this example, after part of the separator 3a is peeled off by the contact claw 166a of the peeling portion 166, the separator 3a is sucked by the suction portion 168 and separated from the conductive layer 3b. Thereby, even if vibration occurs in the peeling block 161, the contact claw 166a of the peeling portion 166 can be prevented from interfering with the conductive layer 3b, and the conductive layer 3b can be prevented from being damaged.

  In the separator peeling device 106 of this example, the separator 3a of the conductive film 3 attached to the cell 1 is peeled from the conductive layer 3b by moving the peeling block 161 (peeling portion) in the processing direction X2. However, the processing direction according to the present invention can be arbitrarily set as long as the direction is parallel to the front and back surfaces of the cell 1. For example, a direction parallel to the front and back surfaces of the cell 1 and orthogonal to the transport direction X1 of the cell 1 may be set as the processing direction. Note that the contact claw 166a of the peeling portion 166 is preferably directed in the processing direction.

  Moreover, the separator peeling apparatus 106 of this invention should just move the peeling part 166 and the cell 1 relatively, and should make the peeling part 166 contact the separator 3a of the electroconductive film 3 affixed on the cell 1. FIG. For example, the peeling part 166 may be fixed, and the peeling part 166 may be brought into contact with the separator 3a of the conductive film 3 attached to the cell 1 by moving the cell 1 in the transport direction X1.

  Moreover, the separator peeling apparatus 106 of this example peels the separator 3a of the electroconductive film 3 affixed on the surface and the back surface of the cell 1. FIG. However, the separator peeling apparatus of this invention should just be the structure which peels the separator of the electroconductive film affixed on either the surface of the cell 1, or the back surface.

  Moreover, the separator peeling apparatus 106 of this example was set as the structure which peels each separator 3a of the some electroconductive film 3 (small piece) affixed on the normal position of the surface of the cell 1, and a back surface. However, the separator peeling device 106 of the present invention can also be used when peeling the separator 3a of the single conductive film 3 attached along the position where the electric wires in the cell 1 are joined.

  Further, the separator peeling device 106 of this example peels the separator 3 a from the conductive film 3 attached to the cell 1. However, the separator peeling device 106 of the present invention can also be used when the separator 3 a is peeled from the conductive film 3 attached to the electric wire 2.

Moreover, the separator peeling apparatus 106 of this example collects the separator 3a peeled off from the conductive layer 3b by the suction part 168. However, the separator peeling device 106 of the present invention may be recovered by being pumped by a pumping unit which is a second specific example of the recovery unit.
Moreover, as the separator peeling apparatus 106 of this invention, it is not necessary to use suction or pressure feeding, for example, you may make it the structure which arrange | positions a separator accommodating part in the part to which the separator 3a peeled by the peeling part 166 falls. In this case, the peeling block 161 is moved in the processing direction until the separator 3a is peeled from the conductive layer 3b without raising the peeling block 161 on the way.

2. Second Embodiment [Separator Separation Device]
Next, a second embodiment of the separator peeling apparatus of the present invention will be described with reference to FIG.
FIG. 8 is a longitudinal sectional view of a peeling block according to a second embodiment of the separator peeling apparatus of the present invention.

  The second embodiment of the separator peeling apparatus has the same configuration as the separator peeling apparatus 106 that is the first embodiment. The second embodiment of the separator peeling device is different from the separator peeling device 106 only in the peeling block 261. Therefore, here, the peeling block 261 will be described, and the description of the holding member, the cylinder, the support member, and the horizontal movement mechanism common to the separator peeling device 106 will be omitted.

  As shown in FIG. 8, the peeling block 261 according to the second embodiment of the separator peeling device includes a base portion 265, a peeling portion 266, a roller 267, a suction portion 268, and an adjustment portion 269. .

  The base portion 265 is formed in a substantially rectangular parallelepiped shape, and has a cell facing surface 265a facing the cell 1 and a back surface 265b which is a surface opposite to the cell facing surface 265a. The base portion 265 is biased toward the cell 1 by a biasing member (not shown) similar to that of the first embodiment. That is, the distance defining mechanism according to the present example includes an urging member (not shown) and the roller 267.

  In the base portion 265, a component storage chamber 265c and a suction hole 265d communicating with the component storage chamber 265c are provided. One end of the suction hole 265d opens to the cell facing surface 265a, and the other end communicates with the nozzle 268a of the suction unit 268.

  The peeling portion 266 is disposed in the component housing chamber 265c and the suction hole 265d of the base portion 265. The peeling portion 266 is formed in a substantially rectangular plate shape, and has a contact blade 266a on one long side. The contact blade 266a contacts the separator 3a of the conductive film 3 attached to the cell 1, and peels the separator 3a from the conductive layer 3b.

  The long side of the peeling portion 266 is set to a length at which the contact blade 266a contacts all the conductive films 3 arranged on the surface of the cell 1 in the direction orthogonal to the conveyance direction of the cell 1. That is, the contact blade 266a of the peeling part 266 peels the separators 3a of the plurality of conductive films 3. Further, the contact blade 266a slightly protrudes from the cell facing surface 265a through the suction hole 265d.

  The peeling portion 266 is fixed to the mounting base 271 with a fixing screw 270. The mounting base 271 is disposed in the component housing chamber 265 c and the suction hole 265 d in the same manner as the peeling portion 266, and is formed in a plate shape that is thicker than the peeling portion 266.

  An inclined surface 271a is formed at the tip of the mounting base 271 that is disposed in the suction hole 265d in order to secure a space for the separator 3a to pass through the suction hole 265d. On the other hand, the rear end portion of the mounting base 271 is disposed in the component housing chamber 265c, and has a screw hole 271b into which an adjustment screw 273 described later of the adjustment portion 269 is screwed.

  At least two rollers 267 are provided with respect to the base portion 265 and are rotatably attached to the base portion 265. At least a part of the roller 267 protrudes from the cell facing surface 265 a and contacts the surface of the cell 1. The rotation axis of the roller 267 is parallel to the cell facing surface 265a and parallel to the direction orthogonal to the transport direction X1 of the cell 1.

  The suction part 268 shows a specific example of the recovery part according to the present invention, and recovers the separator 3a peeled off from the conductive layer 3b. The suction unit 268 includes a nozzle 268a and a negative pressure generating unit (not shown) connected to the nozzle 268a. The tip of the nozzle 268a communicates with the suction hole 265d of the base portion 265.

The adjustment unit 269 is provided to adjust the amount of protrusion of the contact blade 266a with respect to the cell facing surface 265a, and includes an adjustment screw 273 and a compression coil spring 274.
The adjustment screw 273 passes through the base portion 265 and is screwed into a screw hole 271 b provided in the mounting base 271. Inside the compression coil spring 274, a shaft portion of an adjustment screw 273 inserted in the component housing chamber 265c is disposed.

  For example, when the adjustment screw 273 is rotated around one axis, the adjustment screw 273 is inserted into the mounting base 271 and the relative distance between the mounting base 271 and the head of the adjustment screw 273 is shortened. As a result, the mounting base 271 moves to the head side of the adjusting screw 273 against the spring force of the compression coil spring 274. As a result, the peeling portion 266 attached to the mounting base 271 moves to the head side of the adjustment screw 273, and the protruding amount of the contact blade 266a with respect to the cell facing surface 265a is reduced.

  On the other hand, when the adjusting screw 273 is rotated to the other side around the axis, the adjusting screw 273 is extended from the mounting base 271, and the relative distance between the mounting base 271 and the head of the adjusting screw 273 is increased. As a result, the mounting base 271 is biased by the spring force of the compression coil spring 274 and moves to the front of the tip portion where the inclined surface 271a is formed. As a result, the peeling portion 266 attached to the mounting base 271 moves to the front of the contact blade 266a, and the protruding amount of the contact blade 266a with respect to the cell facing surface 265a increases.

  Also in the second embodiment of the separator peeling apparatus configured as described above, the contact blade 266a is made of the conductive film 3 by moving the peeling block 261 in the processing direction X2 opposite to the conveying direction X1 of the cell 1. The separator 3a is contacted from the side, and a part of the separator 3a is peeled off from the conductive layer 3b. The separator 3a partially peeled off from the conductive layer 3b is sucked by the suction portion 268 and peeled off from the conductive layer 3b.

3. Third Embodiment [Separator Peeling Device]
Next, a third embodiment of the separator peeling apparatus of the present invention will be described with reference to FIGS.
FIG. 9 is a front view of a third embodiment of the separator peeling apparatus. FIG. 10 is a side view of the peeling portion according to the third embodiment of the separator peeling device.

  As shown in FIG. 9, the separator peeling device 306 has the same configuration as the separator peeling device 106 (see FIG. 6) of the first embodiment described above. The separator peeling device 306 is different from the separator peeling device 106 only in the peeling block 361. Therefore, here, the peeling block 361 will be described, and the same components as those of the separator peeling device 106 will be denoted by the same reference numerals and description thereof will be omitted.

  The peeling block 361 includes a base portion 165, a peeling portion 366, a roller 167, and a suction portion 168. The base portion 165, the roller 167, and the suction portion 168 are the same as the peeling block 161 (see FIG. 6) of the first embodiment.

  The peeling portion 366 is attached to the base portion 165 via a mounting bracket 367. The peeling portion 366 is formed in a substantially arc shape by bending a needle-like member having flexibility.

  The number of peeling portions 366 is appropriately determined according to the number of small pieces of the conductive film 3 to be attached to the cell 1. For example, when the separator 3a in each small piece of the conductive film 3 is peeled in one operation, the same number of peeling portions 366 as the small pieces in the conductive film 3 may be provided.

  As shown in FIG. 10, the peeling portion 366 includes a fixed piece 371 fixed to the mounting bracket 367, an intermediate piece 372 continuous with the fixed piece 371, and a peel piece 373 continuous with the intermediate piece 372. . A cut 374 a is formed between the fixed piece 371 and the intermediate piece 372, and a cut 374 b is formed between the intermediate piece 372 and the peeling piece 373.

  The cuts 374 a and 374 b are provided inside the bend of the peeling portion 366. By providing these cuts 374 a and 374 b, the peeling portion 366 is easily elastically deformed between the fixed piece 371 and the intermediate piece 372 and between the intermediate piece 372 and the peeling piece 373. The peeling portion 366 is flexibly deformed inside the bending as a whole by elastically deforming between the fixed piece 371 and the intermediate piece 372 and between the intermediate piece 372 and the peeling piece 373.

  A blade edge 373 a formed at an acute angle is provided at the end of the peeling piece 373 opposite to the intermediate piece 372. The blade edge 373a protrudes from the cell facing surface 165a (see FIG. 9) and contacts the conductive film 3 attached to the cell 1 from the side. Further, the base portion 165 (see FIG. 9) is provided with an adjustment portion (not shown) that adjusts the protruding amount of the blade edge 373a with respect to the cell facing surface 165a by changing the mounting position of the peeling portion 366 with respect to the mounting bracket 367. Yes.

  A portion of the peeling piece 373 that forms the outer side of the bending of the peeling portion 366 is a polygonal contact side 373b. The contact side 373b contacts the cell 1 when the separator 3a of the conductive film 3 is peeled off.

[Operation of separator peeling device]
Next, the operation of the separator peeling device 306 will be described with reference to FIG.
FIG. 11 is an explanatory diagram for explaining the operation of the separator peeling device 306.

  In the separator peeling device 306, the upper peeling block 361 and the lower peeling block 361 (see FIG. 9) are opposite to each other only in the vertical direction, and the other operations are the same. Therefore, in FIG. 11, the lower peeling block 361 of the cell 1 is omitted, and the operation of the upper peeling block 361 will be described as an example.

The cell 1 to which the conductive film 3 is attached is conveyed between the peeling blocks 361 and disposed at the processing position.
When the cell 1 is disposed at the processing position, the cylinder 163 (see FIG. 9) operates to move the peeling block 361 in the vertical direction (cell 1 side). Thereby, the contact side 373b of the peeling piece 373 in the peeling part 366 contacts the surface of the cell 1 (refer FIG. 11A). At this time, the cutting edge 373a of the peeling piece 373 in the peeling portion 366 is opposed to the boundary between the separator 3a and the conductive layer 3b of the conductive film 3.

  Note that the peeling block 361 is provided with an adjustment unit (not shown) that adjusts the protruding amount of the peeling piece 373 with respect to the cell facing surface 165a. Therefore, when using conductive films of different types and different thicknesses of the conductive layer, the amount of protrusion of the peeling piece 373 with respect to the cell facing surface 165a is changed by an adjustment unit (not shown). Thereby, the blade edge | tip 373a of the peeling piece 373 can be made to oppose on the boundary of the separator in a conductive film from which a kind differs, and a conductive layer.

  Subsequently, the horizontal movement mechanism 171 (see FIG. 2) operates to move the peeling block 361 in the processing direction X2. Thereby, the blade edge | tip 373a of the peeling part 366 contacts the boundary of the separator 3a and the conductive layer 3b from the side of the conductive film 3. FIG.

  Next, the cylinder 163 (see FIG. 9) is operated to move the peeling block 361 in the vertical direction (cell 1 side) to bring the roller 167 into contact with the surface of the cell 1 (see FIG. 11B).

  At this time, since the upper peeling block 361 is always urged to the cell 1 side by the urging member 169, the height from the surface of the cell 1 to the peeling portion 366 in the upper peeling block 361 is always defined. It becomes constant. In addition, since the lower peeling block 361 (not shown) sandwiches the cell 1 with the upper peeling block 361, the height from the back surface of the cell 1 to the peeling portion 366 in the lower peeling block 361 is defined. Always constant.

  When the roller 167 of the peeling block 361 comes into contact with the surface of the cell 1, a negative pressure generating unit (not shown) of the suction unit 168 is driven, and vacuum suction by the suction unit 168 is started. The vacuum suction by the suction unit 168 may be started before the peeling block 161 is moved to the cell 1 side, for example.

  On the other hand, the peeling portion 366 is bent and deformed so that the notches 374a and 374b are closed because the polygonal contact side 373b is pressed to the cell 1 side in contact with the surface of the cell 1. Thereby, the blade edge | tip 373a of the peeling piece 373 displaces upwards, and the separator 3a of the electroconductive film 3 is rolled up. As a result, the blade edge 373a of the peeling portion 366 peels a part of the separator 3a from the conductive layer 3b.

When the peeling portion 366 (see FIG. 9) of the lower peeling block 361 is bent and deformed, the blade edge 373a of the peeling piece 373 is displaced downward to lift the separator 3a of the conductive film 3. As a result, the blade edge 373a of the peeling portion 366 peels a part of the separator 3a from the conductive layer 3b.
That is, the cutting edge 373a of the peeling portion 366 in the present embodiment is displaced in a direction away from the front surface or the back surface of the cell 1 to lift up the separator 3a of the conductive film 3.

  When the blade edge 373a of the peeling portion 366 peels a part of the separator 3a from the conductive layer 3b, the cylinder 163 (see FIG. 9) operates to raise the peeling block 361 (see FIG. 11C). At this time, when the peeling block 361 is moved also in the processing direction X2 by the operation of the horizontal movement mechanism 171 (see FIG. 2), the peeling block 361 moves obliquely upward.

  When the peeling block 361 is raised, the peeling piece 373 of the peeling portion 366 is separated from the conductive layer 3b. The separator 3a partially peeled off from the conductive layer 3b is peeled off from the conductive layer 3b by being sucked by the suction portion 168.

  That is, in the separator peeling device 306 of this example, after a part of the separator 3a is peeled off by the blade edge 373a of the peeling portion 366, the separator 3a is sucked by the suction portion 168 and separated from the conductive layer 3b. Thus, even if vibration occurs in the peeling block 361, the peeling piece 373 of the peeling portion 366 can be prevented from interfering with the conductive layer 3b, and the conductive layer 3b can be prevented from being damaged.

  In the separator peeling device 306 of this example, the peeling block 361 is moved in the processing direction X2, and the blade edge 373a of the peeling portion 366 is displaced in a direction away from the front surface or the back surface of the cell 1, so that the separator 3a of the conductive film 3 is electrically conductive. Peel from layer 3b. However, the processing direction according to the present invention can be arbitrarily set as long as the direction is parallel to the front and back surfaces of the cell 1. For example, a direction parallel to the front and back surfaces of the cell 1 and orthogonal to the transport direction X1 of the cell 1 may be set as the processing direction. Note that the cutting edge 373a of the peeling portion 366 may be directed in the processing direction.

  In the separator peeling device 306 of this example, the peeling portion 366 and the cell 1 are relatively moved, and the blade edge 373a of the peeling portion 366 is brought into contact with the separator 3a of the conductive film 3 attached to the cell 1. That's fine. For example, by fixing the peeling portion 366 and moving the cell 1 in the transport direction X1, the blade edge 373a of the peeling portion 366 may be brought into contact with the separator 3a of the conductive film 3 attached to the cell 1. .

  Moreover, the separator peeling apparatus 306 of this example peels the separator 3 a of the conductive film 3 attached to the front and back surfaces of the cell 1. However, the separator peeling apparatus of this invention should just be the structure which peels the separator of the electroconductive film affixed on either the surface of the cell 1, or the back surface.

  Moreover, the separator peeling apparatus 306 of this example was configured to peel the separators 3a of the plurality of conductive films 3 (small pieces) attached to the specified positions on the front and back surfaces of the cell 1. However, the separator peeling device 306 of the present invention can also be used when peeling the separator 3a of one conductive film 3 attached along the position where the electric wires in the cell 1 are joined.

  Further, the separator peeling device 306 of this example peels the separator 3 a from the conductive film 3 attached to the cell 1. However, the separator peeling device 306 of the present invention can also be used when peeling the separator 3a from the conductive film 3 attached to the electric wire 2.

Further, the separator peeling device 306 of this example collects the separator 3a peeled from the conductive layer 3b by the suction unit 168. However, the separator peeling device 306 of the present invention may be recovered by being pumped by a pumping unit which is a second specific example of the recovery unit.
Further, the separator peeling device 306 of the present invention does not have to use suction or pressure feeding. For example, the separator accommodating portion may be arranged at a portion where the separator 3a peeled by the peeling portion 366 falls. In this case, the peeling block 361 is moved in the processing direction until the separator 3a is peeled from the conductive layer 3b without raising the peeling block 361 on the way.

4). Fourth Embodiment [Separator Peeling Device]
Next, a fourth embodiment of the separator peeling apparatus of the present invention will be described with reference to FIGS.
FIG. 12 is a side view of the peeling portion according to the fourth embodiment of the separator peeling device of the present invention. FIG. 13 is a development view of the peeling portion according to the fourth embodiment of the separator peeling device of the present invention.

  The fourth embodiment of the separator peeling apparatus has the same configuration as the separator peeling apparatus 306 (see FIG. 9) of the third embodiment described above. The fourth embodiment of the separator peeling device is different from the separator peeling device 306 only in the peeling portion 466. Therefore, here, the peeling unit 466 will be described, and the description of the configuration common to the separator peeling device 306 will be omitted.

  The peeling portion 466 is attached to the base portion 165 (see FIG. 9) via a mounting bracket 367. The peeling portion 466 is formed in a substantially arc shape by bending a plate member having flexibility.

  The number of peeling portions 466 is appropriately determined according to the number of small pieces of the conductive film 3 to be attached to the cell 1. For example, when peeling the separator 3a in each small piece of the conductive film 3 by one operation, the same number of peeling portions 466 as the small pieces of the conductive film 3 may be provided.

  As shown in FIGS. 12 and 13, the peeling portion 466 includes a fixing piece 471 fixed to the mounting bracket 367, an intermediate piece 472 continuous with the fixing piece 471, and a peeling piece 473 continuous with the intermediate piece 472. I have. A notch 474a is formed between the fixed piece 471 and the intermediate piece 472, and a notch 474b is formed between the intermediate piece 472 and the peeling piece 473.

  The notches 474a and 474b are provided on both sides of the peeling portion 466, respectively. By providing these notches 474 a and 474 b, the peeling portion 466 is easily elastically deformed between the fixed piece 471 and the intermediate piece 472 and between the intermediate piece 472 and the peeling piece 473. The peeling portion 466 is flexibly deformed inside the bending as a whole by elastically deforming between the fixed piece 471 and the intermediate piece 472 and between the intermediate piece 472 and the peeling piece 473.

  A contact blade 473a formed at an acute angle is provided at the end of the peeling piece 473 opposite to the intermediate piece 472. The contact blade 473a protrudes from the cell facing surface 165a (see FIG. 9) and contacts the conductive film 3 attached to the cell 1 from the side. Further, the base portion 165 (see FIG. 9) is provided with an adjusting portion (not shown) that adjusts the protruding amount of the contact blade 473a with respect to the cell facing surface 165a by changing the mounting position of the peeling portion 466 with respect to the mounting bracket 367. ing.

  The surface that forms the outer side of the bending of the peeling portion 466 in the peeling piece 473 is a polygonal contact surface 473b. The contact surface 473b contacts the cell 1 when the separator 3a of the conductive film 3 is peeled off.

  Also in the fourth embodiment of the separator peeling apparatus configured as described above, the contact blade 473a is moved to the side of the conductive film 3 by moving the peeling block in the processing direction X2 opposite to the conveying direction X1 of the cell 1. The separator 3a is contacted from the side. Then, the peeling portion 466 is bent and deformed by bringing the contact surface 473b having a polygonal line shape into contact with the surface of the cell 1 and pressing the cell 1 side.

  Thereby, the contact blade 473a of the peeling piece 473 is displaced in a direction away from the front surface or the back surface of the cell 1, and the separator 3a of the conductive film 3 is rolled up. As a result, the contact blade 473a of the peeling part 466 peels a part of the separator 3a from the conductive layer 3b. Thereafter, the separator 3a partially peeled from the conductive layer 3b is sucked by the suction portion 268 (see FIG. 9) and peeled off from the conductive layer 3b.

  The peeling portions 366 and 466 of the above-described third and fourth embodiments are configured to have fixing pieces 371 and 471, intermediate pieces 372 and 472, and peeling pieces 373 and 473. However, the peelable deformable peeling portion according to the present invention is not limited to those having a fixed piece, an intermediate piece, and a peeled piece, and the blade tip, the contact blade, etc. are displaced in a direction away from the cell 1 by elastic deformation. Any shape is acceptable.

  The embodiment of the separator peeling device and the solar cell module assembling device of the present invention has been described above including the effects thereof. However, the separator peeling apparatus and the solar cell module assembling apparatus of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention described in the claims. Is possible.

  For example, in the first to fourth embodiments of the separator peeling device described above, the distance regulating mechanism is configured by the roller that contacts the cell and the biasing member that biases the peeling block. However, the member brought into contact with the cell is not limited to the roller, and a sliding member that slides on the cell may be employed.

In addition, various mechanisms can be used as the distance defining mechanism according to the present invention as long as it regulates the distance from the cell or the electric wire to the peeling portion.
For example, the distance regulating mechanism according to the present invention includes a detection unit that detects a distance from the cell facing surface of the peeling block to the surface of the cell, and controls a cylinder and a motor based on the detection result by the detection unit, You may comprise from the control part which prescribes | regulates the position of an up-down direction.
