Description

  TECHNICAL FIELD The present invention relates to a solar cell tab line affixing and affixing method, and in particular, using CF (Conductive Film) to electrically connect connection electrodes on a cell, which is a module substrate of a solar cell, with tab wires. TECHNICAL FIELD The present invention relates to a solar cell tab wire sticking apparatus and a sticking method thereof.

  Generally, a solar cell module has a structure in which a plurality of solar cells are arranged between a front surface protective material and a back surface protective material, and these solar cells are electrically connected in series to each other by so-called tab wires. It has become. That is, the bus bar electrodes of a plurality of solar cells are electrically connected to each other by a tab wire made of a conductive material such as copper foil, and from a surface protective material such as glass or translucent plastic, and a film such as PET. It is sealed with a sealing material having translucency such as EVA between the back surface protection material.

  By the way, in the conventional solar cell, generally, the connection of the tab wire made of plated aluminum, a conductor, a copper foil, etc. needs to electrically connect a plurality of bus bar electrodes to each other. As disclosed in US Pat.

  However, generally, a solar cell panel has a large warp (for example, about 1 to 3 mm / 1400 mm). Therefore, instead of soldering, as disclosed in the following Patent Document 4, an anisotropic conductive adhesive film ( A device that uses the ACF) to connect the tab lines is already known. Furthermore, according to the following Patent Document 4, it is already known that a connection between a tab wire and a bus bar is made by a resin.

  However, as described above, when the tab wire is attached on the solar cell panel by using an adhesive film or resin instead of the conventional solder, the solar cell panel is warped as described above. When the adhesive film or resin is attached or applied over the entire surface of the joint portion with the tab wire and then pressure-bonded, it is difficult to keep the bonding pressure on the entire surface uniform, and the conductive adhesive film (ACF) which is the bonding material (Including CF and CF) over the entire surface of the joint with the tab wire, there is also a problem that the material cost becomes high. In addition, after affixing an adhesive film or resin on a solar cell panel and then attaching and bonding a foil-like tab wire thereon, the apparatus for that purpose becomes large and the speed is also slowed down. There was a problem.

  Therefore, the present invention has been achieved in view of the above-described problems in the prior art, and more specifically, without increasing the size of the apparatus (that is, downsizing of the apparatus) and its processing. Tabs for solar cells that can realize high-speed operation and can attach tab wires at low cost without damaging solar cell panels with relatively large warpage (curvature) It is an object of the present invention to provide a wire sticking device and a sticking method thereof.

Or a method of cutting a tape-like tab member made of a conductive member into a predetermined length, and temporarily bonding an adhesive conductive film on one surface thereof to form a tab line; The arrangement of the tab line is arranged such that the one surface of the tab line formed by the tab line forming device is arranged so as to straddle between the connection electrodes of the cell on the surface of the solar cell panel horizontally carried into the device. Part and a main pressure bonding part that is arranged on the surface of the solar cell panel by the arrangement device, and for heat-pressing the tab wire on which the conductive film is temporarily pressure-bonded to the solar cell panel, tab The forming portion is provided with a solar cell tab wire sticking device or a sticking method thereof, comprising means for sticking the adhesive conductive film individually on the one surface of the tape-like tab member. The

  Further, in the present invention, in the above-described solar cell tab wire sticking apparatus and method, it is preferable to perform each of the above-described portions on both sides of the solar cell panel that is horizontally loaded, or the main crimping portion. Is preferably constituted by a plurality of pressure-bonding heads arranged along the tab lines arranged on the surface of the solar cell panel or a pressure-bonding roller to perform the main pressure-bonding. In addition, in the present invention, the tab wire forming portion may temporarily press-bond the adhesive conductive film to one surface of the tape-shaped tab member while supplying the adhesive conductive film in a tape shape. preferable.

  In other words, according to the above-described tab wire sticking device according to the present invention, and further, according to the sticking method, when the tab wire for electrically connecting the bus bar electrode of the solar battery cell is pasted on the panel side, Instead, a member in which a conductive resin film is formed into a tape shape is attached to the tab wire used for electrical connection by using the above-described CF sticking apparatus instead of sticking the whole surface. This reduces damage to the panel during pasting, reduces the amount of expensive conductive resin film used, and attaches it to the solar cell panel without placing unnecessary stress on the panel. Is possible. At that time, by arranging the sticking device symmetrically on both sides of the solar cell panel horizontally loaded therein, the device can be made compact without increasing the size of the device. In addition, in the main crimping portion of the solar cell tab wire, by using a plurality of crimping heads or crimping rollers arranged along the tab wire, the solar cell panel generally has a relatively large size. In spite of warping (curving), it is possible to reliably perform the main pressure bonding. Further, in the tab wire forming portion, the adhesive conductive film is formed into a tape shape, and the adhesive conductive film is temporarily pressure-bonded to one surface of the tape-shaped tab member while continuously supplying the tape using a reel. According to this, in addition to downsizing of the apparatus, a practically excellent effect of enabling an efficient operation of attaching the tab line for solar cell is exhibited.

<Tab line cutting device>

  In FIG. 2, an adhesive conductive film (CF) is pasted (temporarily pasted) to the tab wire member TB ′ which is a tape-like plated metal, aluminum, or copper foil to be a tab wire. Is cut out to a predetermined length (the length in the longitudinal direction of the solar cell panel SP) to form a tab line TB. As is apparent from the figure, this apparatus includes a reel 21 around which a tape-shaped tab wire member TB ′ is wound, a guide roller 22 disposed at a position facing the reel, and a conductive film CF. The cutter 23 for cutting the tape-like tab wire member TB ′ after the tape is attached, and the tip portion of the tab wire member TB ′ cut by the cutter is sandwiched and held, and then a predetermined sticking pitch And a chuck 24 that moves by a distance (see arrows in the figure). In the present invention, a detailed description will be given below between the reel 21 and the guide roller 22, but a conductive film is placed on one surface of the tape-like tab wire member TB at a predetermined interval. A CF sticking device 25 is provided for intermittent sticking (hereinafter referred to as “individual piece sticking”). That is, according to such a configuration, the adhesive conductive film CF is pasted on the tab wire member TB ′ wound on the reel 21, and the tab wire TB ′ is cut into a predetermined length to cut the tab wire. Let it be TB. Reference numerals 26 and 27 in the drawing denote guide rollers for guiding the tab wire member TB 'supplied from the reel 21, respectively.

In addition, in the above-described tab wire cutting device, the state of the tab wire TB obtained by sticking the adhesive conductive film CF on the wound tab wire member TB ′ is shown in FIG. . In addition, the length (L) of the conductive film CF to which the individual pieces are stuck is, for example, about 10 mm to 100 mm. In this way, the conductive film CF used as an adhesive member for attaching the tab wire TB to the surface of the solar cell panel SP can be applied to the panel without applying unnecessary stress to the panel. It can be attached to the solar cell panel.
<Tab line pasting device>

  Next, in FIG. 3, the adhesive conductive film CF is pasted on the surface by the apparatus shown in FIG. 2, and the tab wire TB cut into a predetermined length is put in the pasting apparatus 100. An apparatus for pressure-bonding the tab wire TB to the surface of the solar cell panel SP after being disposed at a predetermined position of the carried solar cell panel SP is shown. That is, this apparatus sucks and holds the tab wire TB cut to a predetermined length by the apparatus of FIG. 2, for example, by vacuum, and transfers it by a moving mechanism (not shown) (see the arrow in the figure). ) Therefore, the tab line holding and transferring device 31 for arranging the tab line TB at a predetermined position of the solar cell panel SP, and the cut tab line TB placed on the tab line holding and transferring device 31 below the tab line holding and transferring device 31 From the upper side in a state where the tab wire TB is arranged at a predetermined position on the surface of the solar cell panel SP by the moving table 32 for carrying to the adsorption surface (see the arrow in the figure) and the tab wire holding and transferring device 31.

The predetermined position on the surface of the solar cell panel is a hatched portion in the figure, specifically, a portion where the connection electrodes of the solar cell panel cell are exposed and arranged on the surface, and these electrodes are It is arranged to straddle. Further, the main crimping head 33 is composed of a plurality of crimping heads. Moreover, the code | symbol 34 in a figure has shown the table for mounting the solar cell panel SP conveyed in the inside of the sticking apparatus in a predetermined position.

  Subsequently, the details of the CF sticking device 25 for sticking the conductive film CF to the surface of the tape-like tab wire member TB ′ in FIG. 2 will be described below. The conductive film CF to be piece-attached by the CF sticking device 25 will be described with reference to FIG.

As is apparent from the figure, the conductive film CF is formed by laminating a CF layer 50, which is an adhesive conductive resin layer, on the separator 51. The separator 51 has a release layer on the lamination surface of the CF layer 50. Therefore, after the CF layer 50 is attached to the surface of the tab wire member TB ′, the separator 51 is peeled off from the release layer. Only the CF layer 50 can be left on the surface. The CF layer 50 is formed by uniformly dispersing conductive particles 50b, which are sufficiently small particles, in a binder resin 50a having thermosetting properties and adhesive strength. Conductivity is obtained, and the bus bar electrodes of a plurality of solar cells constituting the panel can be electrically connected by thermocompression bonding.
<CF sticking device>

  Next, FIG. 6 attached is a perspective view showing the entire configuration of the CF sticking device 25 described above. In this figure, the CF sticking device 25 is positioned by providing a guide roller in the Y direction in the figure, and the X direction is positioned in the X direction by feeding the chuck 24. That is, by these moving mechanisms, the tab line TB and the CF sticking device 25 are aligned in the X direction and the Y direction. The CF sticking device 25 is roughly divided into a main body part 63, a sticking head part 64, a CF reel 65, and a CF sticking part 66.

  Next, FIGS. 7 and 8 are diagrams for explaining a more detailed configuration and operation of the CF sticking device 25, that is, FIG. 7A is a side view of the CF sticking device 25, FIG. FIG. 8B is a front view of the CF sticking device 25, and particularly shows a part of the CF sticking portion 66 and the sticking head portion 50. FIG. 8 shows the sticking operation by the CF sticking device 25 described above. It is the flowchart which showed.

  First, the tape-like conductive film CF wound around the CF reel 65 is sent out from a plurality of guide rollers 701, 702, 703 to a predetermined position below the crimping blade 704 (Step 1 in FIG. 8). Then, a so-called half-cut is performed in which the CF layer 50 (see FIG. 5) of the conductive film CF is cut by the half-cut unit 705 (Step 2). After half-cutting, the base 706 on which the components of the CF sticking portion 66 are installed and the crimping blade 704 are lowered to the lower blade 707, and the CF tape is heated by the crimping blade 704 heated by the heater block 708 for a required time. Crimp (Step 3). Thereafter, the crimping blade 704 is raised and the CF layer 50 is cooled (Step 4). By the peeling process described below, the separator 51 is peeled from the CF layer 50 fixed to the surface of the tab wire member TB ′ (Step 5), and the process is terminated. Thereafter, the tab wire member TB 'is moved by a predetermined length, and Step 1 to Step 5 are repeated again, whereby the conductive film CF is stuck on the surface of the tab wire member TB'. Note that reference numerals 709 and 710 in FIG. 7A both serve as feed rollers for discarding the separator 51 into the suction block 711. Moreover, the code | symbol 712 of the said FIG. 7 (B) is a parallel auxiliary guide, and the code | symbol 713 shows a peeling roller.

  Further, attached FIG. 9 is a perspective view showing a detailed configuration including the CF sticking part and sticking head part 64 and a part of the main body part 63 shown in FIG. In this figure, in addition to the crimping blade 704 and lower blade 707 having the heater block described above, the pasting head portion 64 includes a cylinder body 901, a pusher rod 902 that extends from the cylinder body and applies a pressure load to the crimping blade 704, and A cylinder fixing plate 903 for fixing the cylinder body is provided. The posture of the crimping blade 704 is moved up and down by an arm 904 connected to the cylinder fixing plate 903 from the main body 53, and the arm 904 is controlled by a posture control unit (not shown) provided inside the main body 53.

  Further, on the CF sticking part, on the right side of the sticking head part 64, the arm 905 to which the base 706 shown in FIG. 7 is fixed, and the conductive film CF is always fixed to the tab wire member TB ′. There are a parallel guide roller 703 and a parallel auxiliary guide roller 702 which are kept substantially parallel. Further, on the left side of the sticking head portion 64, there are a peeling roller 713, a pressing parallel guide roller 701 and a parallel auxiliary guide 712 that serve to keep the CF parallel.

  Further, on the left side of the sticking head part 64, there is a peeling roller driving part 950 for peeling the separator 51 (constituting members are indicated by reference numerals 951 to 958). The peeling roller driving unit 950 includes a peeling roller moving plate 951 that travels on the rail 955 and moves the peeling roller 713 and the pressing parallel guide roller 701 integrally to the left and right, and an L-shaped two-side link. A link arm 953 having a rotatable fulcrum 952 to which a base 907 is fixed at an intersection of the sides, a cylinder 954 for driving the link arm 953, and the like. One end of the link arm 953 is rotatably connected to the pusher rod 956 of the cylinder 954, and the other end side. A fixing pin 957 fixed to the peeling roller moving plate 951 is connected to a slidable elongated groove 958.

  In such a configuration, the pusher rod 956 is expanded and contracted, and the link arm is rotated about the fulcrum 952 so that the fixed pin 957 slides in the elongated groove 958. Therefore, the peeling roller moving plate 951 moves in the X direction, and the peeling roller 713 and the pressing parallel guide roller 701 move together in the X direction. As a result, the peeling roller moving plate 951 is moved from the separator collection side (left) shown in FIG. 7 to the tape-like conductive film CF supply side (right), and thus the peeling roller 713 and the pressing parallel guide roller 701 are moved. 5 can be peeled from the CF layer 50. The separator 51 shown in FIG.

  Reference numeral 908 in the figure is a cylinder for raising / lowering the base 907. When descending, the conductive film CF between the parallel guide roller 703 and the pressing parallel guide roller 701 is placed on the surface while being kept substantially parallel to the tab wire member TB ′. The base 907 is moved so that the separator 501 is separated from the tab wire member TB ′.

  Further, based on the mechanism described above, the separator peeling process shown in Step 5 of FIG. 8 will be described in detail with reference to FIG.

  FIG. 10A shows a state where the press-fit blade 704 is raised to the standby position after the tape-like conductive film CF is heated and pressurized. Only the separator 51 exists in the left region from the left end C of the crimping blade 704, and the tape-like conductive film CF having the CF layer 50 and the separator 51 exists in the right region from the left end.

  FIG. 10B shows a state in which the peeling roller 713 and the pressing parallel guide roller 701 are integrally moved by the peeling roller driving unit 950 shown in FIG. 9 in the right direction (CF supply direction). At this time, as shown in the drawing, the separator 51 is sandwiched between the peeling roller 713 and the pressing parallel guide roller 701. The peeling roller 713 contacts the peeling surface side 51a of the separator 51 with the CF layer 50, and moves in a non-contact manner with the CF layer 50 while being separated from the tab wire member TB '. On the other hand, the pressing parallel guide roller 701 moves while pressing the surface 51b of the separator 51 opposite to the peeling surface 51a. In this way, the peeling roller 713 moves in a non-contact manner so that dust or the like does not adhere to the CF layer 50. On the other hand, the pressing parallel guide roller 701 moves while pressing the surface 51b opposite to the peeling surface side that does not affect the performance of the CF layer 50. At this time, it is desirable that the pressing parallel guide roller 701 presses the CF layer 50, that is, the entire tape-like conductive film CF, but it may be slightly lifted from the film. In the case of floating, the separator is pressed to the substrate side.

  As a result, since the separator 51 is gradually peeled off from the CF layer 50 below the pressing parallel guide roller 701, no brute force is applied, and it depends on the thickness of the separator and the adhesive strength of the CF layer. The separator can be peeled stably.

  FIG. 10C shows a state where the peeling roller 713 and the pressing parallel guide roller 701 are moved to the right end of the CF layer pasting portion and the peeling processing described in FIG. 10B is completed. FIG. 10D shows a state where the head is raised after the peeling process is completed, and the peeling roller 713 and the like are separated from the tab wire member TB ′.

  According to the configuration of the CF sticking device 25 described above, no brute force is applied, and the separator can be peeled stably without depending on the thickness of the separator and the adhesive strength of the CF layer. Moreover, according to the above structure, since the contact surface with the separator of a peeling roller does not contact with CF layer, it is not necessary to consider the material in particular.

  In the CF sticking apparatus described above, the peeling roller 713 is provided beside the pressing parallel guide roller 701. Instead, as shown in FIG. By maintaining the shape, a stable force can be further applied to the release surface.

  With the above CF sticking device, the conductive film CF is stuck individually on the surface, and the tab wire TB cut to a predetermined length is then placed in the sticking device 100 as described above with reference to FIG. The solar cell panel SP carried in is arranged at a predetermined position, and is fixed by being thermocompression-bonded by the main pressure bonding head 33, and, together with the tab wire made of copper foil, depending on the characteristics of the conductive film CF, The bus bar electrodes of the plurality of solar battery cells are electrically connected to each other. That is, in the present invention, as described above, the main pressure bonding is performed by the main pressure bonding head 33 including a plurality of pressure bonding heads in consideration of a relatively large warpage of the solar cell panel (curving: for example, about 1 to 3 mm / 1400 mm). It is carried out. According to this, each of the plurality of pressure bonding heads can be appropriately adjusted according to the warp (curvature) of the solar cell panel, and therefore, it is preferable that unnecessary stress is not applied to the panel. Alternatively, although not shown here, for example, a so-called pressure-bonding roller in which a solar cell panel SP with a conductive film CF attached is sandwiched between a pair of rollers and heat-pressed is used. .

  As is clear from the above description, according to the solar cell tab wire sticking device and the sticking method described above in detail, the tab wire for electrically connecting the bus bar electrodes of the solar cells is provided on the panel. When affixing to the panel side, instead of the panel side, a member in which a film of a conductive resin is taped is replaced with a so-called CF sticking device instead of sticking the entire surface to a tab wire used for electrical connection. , Paste individual pieces. As a result, the amount of expensive conductive resin film used can be reduced and the panel can be attached to the solar cell panel without applying unnecessary stress to the panel. Further, at that time, as shown in FIG. 1, the sticking device is arranged symmetrically on both sides of the solar cell panel horizontally loaded therein without causing the device to be enlarged. The device can be made compact. In addition, in the main crimping portion of the solar cell tab wire, by using a plurality of crimping heads or crimping rollers arranged along the tab wire, the solar cell panel generally has a relatively large size. In spite of warping (curving), it is possible to reliably perform the main pressure bonding. Also, in the tab wire forming part, the adhesive conductive film is temporarily crimped to one surface of the tape-like tab wire member while the adhesive conductive film is formed into a tape shape and is supplied transferably using a reel. By doing so, the device can be made compact, and an efficient solar cell tab wire attaching operation can be performed.
