EMBODIMENT OF THE INVENTION: C TECHNICAL FIELD OF THE INVENTION The present invention relates to a solar cell tandem manufacturing apparatus and a manufacturing method for manufacturing a solar cell tandem by connecting a plurality of solar battery cells by a wiring material, and using the solar energy An adhesive attaching device and an adhesive attaching method used in each of the battery tandem manufacturing apparatus and the manufacturing method, and a wiring material pressing device and a wiring material pressing method. BACKGROUND OF THE INVENTION Since the output of each solar cell unit is about several w, a plurality of solar cells connected by solar cells are often arranged in series to cover a glass-sealed solar cell module for use as a solar cell. The solar cell is connected to the light-receiving surface of the solar cell, and the electrode is electrically connected to the back Φ-shaped electrode of the adjacent solar cell. In the meantime, a low-resistance material such as solder copper is used as a wiring material. However, since the linear expansion coefficient of the wiring member is larger than the linear expansion coefficient of the semiconductor substrate used for the solar cell unit, the wiring material connected to the solar cell unit shrinks when it returns to normal temperature, and is in the solar cell unit. (4) Producing pressure. As a result, there is a problem that warpage occurs in the battery unit of too 1%. Therefore, in recent years, this problem has been avoided by using a resin battery at a temperature lower than the melting temperature of the solder (for example, l3 〇 ° C to 180 〇 hardened resin adhesive to follow the solar cell in 201205854. More specifically The solar cell tandem manufacturing apparatus includes an adhesive attaching device and a wiring material pressing device, and a resin adhesive is attached to the electrode of the solar cell in the adhesive attaching device, and thereafter, the wiring material pressing device is attached The wiring material is followed by an electrode to which a resin adhesive is attached. The adhesive attaching device has the following problems. In the solar battery cell, since the electrode is formed on the light receiving surface and the back surface, it is necessary to attach a resin adhesive agent on both surfaces thereof. In a general adhesive attaching apparatus, first, a resin adhesive is attached to the electrode of one surface, and then a resin adhesive is attached to the other electrode. However, when pasting a plurality of times, the sticker is attached. The heat or pressure of the time is applied to the solar cell unit, causing the solar cell unit to be damaged. Also, the time required for attaching In addition, there is a problem that the production capacity of the solar cell series is reduced. In addition, the wiring material pressing device has the following problems. In order to harden the resin adhesive, the wiring material and the electrode of the solar battery cell are pressed, and the non-heating ratio is obtained. The time required for soldering is longer (for example, 15 seconds). Therefore, Patent Document 1 discloses that the time required for the pressing can be shortened by pressing the wiring member against the electrode by the following processes A to D. (Process A) - A thermosetting resin adhesive is placed on the electrode on the light-receiving side of the solar cell, and a wiring material for connecting the adjacent solar cell is placed. A wiring member that connects the other solar cell is disposed on the electrode on the back side of the solar cell.

Fig. 4 is a side view showing a manufacturing apparatus (hereinafter, manufacturing apparatus) 100 of a solar battery string. The manufacturing apparatus of Fig. 4 includes an inspection device 3A, a subsequent agent attaching device 40, a wiring material input device 5A, a wiring material pressing device 6A, and a solar cell early input device 70. In the manufacturing apparatus 1 of the same drawing, the solar battery cell 20 of Fig. 2 is manufactured by using the solar battery cell 10 of Fig. 1 . The inspection device 30 performs inspection of whether or not the solar battery unit has a shape such as a crack, and the solar battery unit is placed in the skirt 70 to perform position adjustment in such a manner that the solar battery unit 10 can be held at the correct position. The adhesive attaching device 40 is attached with a resin adhesive 22 on the bus electrode 12 formed on the front surface and the back surface of the solar battery cell 10, respectively. The wiring member input device 50 is placed in the wiring member crimping device 60 in accordance with the height difference of the wiring member 21. In the wiring material pressing device 60, the resin adhesive 22 is pressurized and heated, and then the wiring member 21 is pressed against the bus electrode 12 of the solar battery cell 10.

Attachment device 13 201205854 40 inputs. Then, the adhesive attaching means 4 attaches the resin adhesive 22 to the bus electrode 12 of the solar cell b unit 1 (step S2). The thinner of the adhesive attaching device 4 will be described later, but the adhesive attaching device 4 is formed by forming three bus electrodes on the front surface and the back surface of the solar battery cell 10 to simultaneously attach the resin. The agent 22 can reduce the load on the solar battery cell 10 based on heat or pressure, and can be attached in a short time. Then, the wiring material input device 5 is used to introduce the wiring member 21 having three steps of the height difference into the wiring material pressing device 6 (in this case, as shown in Fig. 4, the wiring members 21 are sandwiched). The height difference is placed at the end of each of the bus electrodes 12 on the surface side of the solar cell unit 1 of the wiring material pressing device 60.

At this time, the solar battery unit 1 is replaced by the solar battery unit 1 The bus electrode 12 on the back side is placed so as to be placed on each of the wiring members 21. Then, the wiring member pressing device 60 presses and heats the wiring member 60, and the wiring member 21 and the solar battery unit 1 are attached. The meandering electrode 12 of the crucible is pressed (step S5). The details of the wiring material pressing device 6A will be described later. However, as will be described later, the wiring material pressing device 60 can be improved by dividing the heating into a plurality of processes. In addition, since each of the solar battery cells 10 is pressed, the wiring material pressing device 6 can be miniaturized. Hereinafter, the adhesive attaching device of the first feature of the present embodiment 201205854 40 is a front view of the adhesive attaching device 40, and Fig. 7 is a side view of the sixth drawing from the left side of the paper. The adhesive attaching device 4 is provided with the upper attaching portion. 41 a, and the attaching portion 41 b. The upper attaching portion 413 is attached to the bus electrode 12 (hereinafter, simply referred to as the electrode 12) on the surface side of the solar cell 10, and the resin adhesive 22 is attached thereto, and the lower attaching portion 41b A resin adhesive 2 2 is attached to the electrode 12 on the back side of the solar cell unit 10. The upper attaching portion 4la has three supply reels 42a, a half-cut portion 43a, and a pressing member 44a. The roller 45a, the three recovery reels 46a, and the transport rollers 471a to 474a are stripped. The three supply reels 42a are provided in accordance with the interval of the electrodes 12 of the solar cell unit 1. The supply reels 42a are wound around each other. a strip of resin adhesive 22 with release paper 23 ( Hereinafter, the resin adhesive 24) to which the release paper is attached is referred to. When the conveyance roller (first conveyance roller) 471a is rotated, the resin adhesive 24 with the release paper is pulled out from the supply reel 42a, and supplied to the half. The cutting portion 43a is further provided with a resin adhesive 24 attached to the release paper, and a resin adhesive 22 is provided on the outer side of the upper attachment portion 41a, and a release paper 23° half-cut portion 4 3 a is provided on the inner side. The resin adhesive 22 with the release resin resin adhesive 24 is cut along the length of the electrode 12. The transport roller (second transport roller) 472a is rotated, and the resin adhesive 24 with the release paper is attached from the half cut portion. 43a is supplied to the opposite position of the electrode 12 of the solar cell unit 10. The pressing member 44a pressurizes and heats the resin adhesive 24 with the release paper on the electrode 12 on the surface side of the solar battery cell 10, and presses the resin 22 and the electrode 12 against the electrode 12. The stripping roller 45a strips the release paper 23 from the resin-attached agent 24 with the release paper. The take-up reel 46a recovers the peeled release paper 23 when the transport rollers 473a, 474a are rotated.

Further, in the same figure, three resin adhesives 24 with release paper are cut by one half-cut portion 43a, but one of the three half-cut portions 43a may be separately cut by one resin adhesive 22. The structure of the attaching portion 41b is substantially the same as that of the above-mentioned attaching portion 41& in the sixth and seventh figures, the respective structural members of the attaching portion 41b are attached with the symbol "b". However, as shown in Fig. 7, the pressing member 44b is different from the opening of the pressing member 44a. The reason for this is that the solar battery cell input device 7 is configured to hold the upper surface of the battery unit ίο, and since the pressing member 44a of the upper attaching portion 41a is formed with irregularities, the pressing member 44a can avoid the solar cell early element. The input device 70 presses the resin adhesive 22 and the electrode 12. The pressing member (first pressing member) 44a and the pressing member (second pressing member) 44b constitute a pressing portion. Further, the transport rollers 473a, 473b, 474a, and 474b and the recovery reels 46a and 46b constitute a collecting portion. Fig. 8 is a view showing the steps of Fig. 5 in order to show the process of attaching the resin to the electrode 22 of the solar cell unit 1 (). First, the resin adhesive 24 to which the paper is attached is placed in advance on the supply reels 42, 42b (step S11). Next, the solar battery unit ίο is put into the adhesive attaching device 40 by the solar battery unit input device 7 (step S12). More specific,

之各電極12附有剝離紙之樹脂接著劑24會接觸。又，如第U 圖所示，在步驟S14，樹脂接著劑22係配合電極12的長度被切割。在此，如第12圖及第13圖所示，對於在下面貼附部41b 之壓著構件44b的表面為平坦，而在上面貼附部41 a之壓著構件44a的表面則被形成為凹凸。此因為太陽能電池單元1〇之上面側太陽能電池單元投入裝置70會把持之故。即，壓著構件44a為凹部避開太陽能電池單元投入裝置7〇前端的把持部’以凸出部分使附有剝離紙之樹脂接著劑24與太陽能電池單元10之電極12接觸。再者’壓著構件44a、44b，係約4、5秒間，一面夾著上下的附有剝離紙之樹脂接著劑24及太陽能電池單元10之電極12加壓，一面以比樹脂接著劑22之軟化溫度更高較硬化溫度更低的溫度’例如以5〇°C〜90°C予以加熱。藉此，樹脂接著劑22軟化貼附在太陽能電池單元1〇之電極12。其後，上面貼附部41a的壓著構件44a會上昇，下面貼附部41b 的壓著構件44b會下降。如第10圖至第13圖所示，因為在所有的電極12同時把附有剝離紙之樹脂接著劑24加壓及加熱，只要一度執行第8 圖之步驟S15的製程，可在所有的電極12貼附接著劑。因此’減輕基於熱或壓力對於太陽能電池單元1〇之負荷，而 201205854 且，可在短時間執行貼附。其次，把剝離紙23從樹脂接著劑22剝取（步驟S16)。第 14圖係把剝離紙2 3剝取時之接著劑貼附裝置4 0的正視圖。如同圖所示，藉由氣缸等把剝取滾輪45a、45b—面在太陽能電池單元10之上及下移動，一面藉由夾頭（無圖示）把剝離紙23從兩面夾住拖拉，從貼附在太陽能電池之電極12的樹脂接著劑22將剝離紙23剝取。剝取結束時，剝取滾輪45a、 45b回到如第6圖所示之原來位置。被剝取之剝離紙23，係藉由運送滾輪473a、474a、473b、474b會旋轉，而被回收捲筒46a、46b捲取。其後，藉由太陽能電池單元投入裝置70太陽能電池單元10從貼附裝置被取出（步驟S17)。藉由以上，可將樹脂接著劑22貼附在太陽能電池的電極12。如此，在本實施形態之接著劑貼附裝置40，僅使用與太陽能電池單元10之電極12同數的附有剝離紙之樹脂接著劑24，從太陽能電池單元10的表面側及背面側夾進予以加壓及加熱。因此，所有電極12可同時貼附樹脂接著劑22，可減輕對於太陽能電池單元10的負荷，同時，可縮短貼附樹脂接著劑22的時間。其次，關於本實施形態之第2個特徵之配線材壓著裝置 60詳細予以說明。第4圖之配線材壓著裝置60係具備有：投入部71、預壓著部72、正式壓著部73、第1加熱部74、第2加熱部75、此等各部共同使用之運送裝置61及加熱裝置62。從投入部71 19 201205854 到第2加熱。卩75之各部，係在運送裝置“上佔有大約太陽此電池單元10之1片分的空間。運送裝置61係把太陽能電池單元10從投入部71到第2 加熱部75之順序’每在各階段處理結束時，運送到下-個 1¾丰又。加熱裝置62係把太陽能電池單元1〇予以加熱。加熱裝置62係、在從投入部71到第2力口熱部75之各部，可分別以不同的溫度加熱太陽能電池單元1〇。在投入部71，會被投入配線材21及樹脂接著劑22貼附在電極12之太陽能電池單元10〇預壓著部72係具有按壓構件63 ’藉由基於按壓構件63之加壓及基於加熱裝置62之加熱，把配線材21與太陽能電池單元1〇預壓著。正式壓著部 73係下面具有水平加壓構件64，在樹脂接著劑22加上壓力把包含在樹脂接著劑22之錄等的導電性粒子潰裂，而獲得導電性。再者’在加壓構件64的下面設置有加熱裝置64a，配合加熱裝置62 ’加熱樹脂接著劑22。第1加熱部74及第2 加熱部75共有非接觸加熱裝置65，加熱樹脂接著劑22使其硬化。非接觸加熱裝置65，係例如IR(紅外線)燈、IH(誘導加熱）、熱空氣等。第15圖係為了把配線材21壓著在太陽能電池單元1〇的製程圖，係詳細顯示第5圖之步驟S5者。首先，太陽能電池單元投入裝置70係把貼附有樹脂接著劑22之太陽能電池單元10，配線材投入裝置50係把配線材21，分別投入配線材壓著裝置60的投入部（步驟S21)。更具體的，係太陽能電池單元投入裝置70係把太陽能電池單元10投入已被投入之配 201205854 線材21之上，配線材投入裝置50係把設有高低差之配線材 21投入在太陽能電池單元1〇之上。投入部71，係為了其次的製程’使用加熱裝置62預熱樹脂接著劑22亦可。步驟S21的製程所需要的時間，係例如為6秒鐘。太陽能電池單元10及配線材21—被投入時，運送裝置61將此等運送到預壓著部72，同時其次的太陽能電池單元10及配線材21會被投入。即，在6秒間以一片的比率太陽能電池單元 10連續不斷地被投入於投入部71。其次’在預壓著部72方面，藉由加熱裝置62以比樹脂接著劑22之軟化溫度更高較硬化溫度更低的溫度，例如一面以50°C〜90°C予以加熱，一面在按壓構件63把配線材21 及太陽能電池單元10加壓，使樹脂接著劑22軟化把配線材 21與太陽能電池單元1〇預壓著（步驟S22)。因為在太陽能電池單元10之表面及背面的相同位置形成電極12，太陽能電池單元10之表面及背面的雙方之配線材21會被預壓著。藉此，在以後的製程，可防止配線材21在太陽能電池單元1〇上離開原來位置。步驟S22的製程所需要的時間，係例如為3秒鐘。前面的太陽能電池單元10之投入製程（步驟S21)因為需要6秒鐘，本製程以3秒鐘結束，其次的太陽能電池單元1〇並非立即從投入部71被運送到預壓著部72。因此，預壓著以3秒鐘即結束，再待機3秒鐘，在預壓著部合計停留6秒鐘之後，運送裝置61把太陽能電池單元1〇從預壓著部72運送到正式壓著4 73 ’同時從投人部71把其次的太陽能電池單元^〇運 21 201205854 送到預壓著部72。在正式壓著部73方面，用加壓構件64以2〜3MPa左右將樹脂接著劑22加壓予以正式壓著。藉此，被包含在樹脂接著劑22之導電性粒子會潰裂，而獲得導電性。此外，加壓構件64的下面成為平坦。因為在太陽能電池單元10的上面被載置有配線材21，以加壓構件64加壓之際，加壓構件64 不會與太陽能電池單元10有所接觸。在此’在加壓構件64的下部設置有加壓裝置64a，不僅加壓，亦可為了使樹脂接著劑22硬化之加熱。正式壓著所需要的時間’係例如為3秒鐘，使樹脂接著劑22硬化所需要的時間，係例如為15秒鐘《因此，假設使用加壓構件64及加壓裝置64a，與正式壓著同時使樹脂接著劑22加熱到完全硬化的情況，有需要加熱15秒鐘。如此一來，此製程成為瓶頸，使整體的產能降低。亦即，從太陽能電池單元1〇投入配線材壓著裝置6〇到配線材21對其太陽能電池單元1〇之壓著結束所需要的產距時間(takt time) ’為6秒(步驟S21)+6秒(步驟S22)+15秒(為了正式壓著及使樹脂接著劑22完全硬化的加熱15秒鐘）=27 移，產忐係因為使樹脂接著劑22硬化的加熱需花μ秒鐘，所以變成每15秒鐘1個（每分鐘4個）的太陽能電池單元1〇〇因此，在本實施形態，迄今之製程（步驟S21、S22及正式壓著）之最長時間為着眼於步驟S21的6秒鐘，在步驟S23 並不使樹脂接著劑22完全硬化，為了硬化之加熱分成複數製程進行。The resin adhesive 24 to which the respective electrodes 12 are attached with release paper is in contact. Further, as shown in Fig. U, in step S14, the length of the resin adhesive 22 is matched with the length of the electrode 12. Here, as shown in Figs. 12 and 13, the surface of the pressing member 44b of the attaching portion 41b is flat, and the surface of the pressing member 44a of the attaching portion 41a is formed as Bump. This is because the solar cell input device 70 of the upper side of the solar cell unit 1 is held. In other words, the pressing member 44a is a recessed portion that avoids the grip portion of the tip end of the solar battery cell input device 7, and the protruding portion brings the resin adhesive 24 with the release paper into contact with the electrode 12 of the solar cell unit 10. Further, the pressing members 44a and 44b are pressed between the upper and lower resin adhesives 24 with the release paper and the electrode 12 of the solar battery cell 10 for about 4 and 5 seconds, while being pressed by the resin adhesive 22 The softening temperature is higher than the hardening temperature, for example, heating at 5 ° C to 90 ° C. Thereby, the resin adhesive 22 is softened and attached to the electrode 12 of the solar battery cell 1 . Thereafter, the pressing member 44a of the upper attaching portion 41a is raised, and the pressing member 44b of the lower attaching portion 41b is lowered. As shown in Figs. 10 to 13, since all the electrodes 12 are simultaneously pressurized and heated by the resin adhesive 24 with the release paper, as long as the process of the step S15 of Fig. 8 is once performed, all the electrodes can be used. 12 attached adhesive. Therefore, the load on the solar battery unit based on heat or pressure is reduced, and 201205854 can be attached in a short time. Next, the release paper 23 is peeled off from the resin adhesive 22 (step S16). Fig. 14 is a front view of the adhesive attaching device 40 when the release paper 2 3 is peeled off. As shown in the figure, the stripping rollers 45a, 45b are moved over and under the solar cell unit 10 by a cylinder or the like, and the release paper 23 is pulled from both sides by a chuck (not shown). The resin adhesive 22 attached to the electrode 12 of the solar cell peels off the release paper 23. At the end of the stripping, the stripping rollers 45a, 45b return to the original position as shown in Fig. 6. The peeled release paper 23 is taken up by the take-up reels 46a, 46b by the conveyance rollers 473a, 474a, 473b, and 474b rotating. Thereafter, the solar battery unit 10 is taken out from the attaching device by the solar battery cell input device 70 (step S17). By the above, the resin binder 22 can be attached to the electrode 12 of the solar cell. As described above, in the adhesive attaching device 40 of the present embodiment, only the resin adhesive 24 with the release paper of the same number as the electrode 12 of the solar battery cell 10 is used, and the adhesive is attached from the front side and the back side of the solar battery cell 10. Pressurize and heat. Therefore, all of the electrodes 12 can be attached with the resin adhesive 22 at the same time, the load on the solar battery cells 10 can be alleviated, and at the same time, the time for attaching the resin adhesive 22 can be shortened. Next, the wiring member crimping device 60 according to the second feature of the embodiment will be described in detail. The wiring material crimping device 60 of FIG. 4 includes an input unit 71, a pre-clamping unit 72, a final pressing portion 73, a first heating unit 74, a second heating unit 75, and a transport device that is used in common by these units. 61 and heating device 62. From the input unit 71 19 201205854 to the second heating. Each of the 卩75 is in a space in which one of the solar cells 10 is occupied by the transport device. The transport device 61 is in the order of the solar battery unit 10 from the input unit 71 to the second heating unit 75. At the end of the stage process, the heat transfer device 62 heats the solar battery cells 1 to the next. The solar cell unit 1 is heated at a different temperature. In the input unit 71, the solar cell unit 10 is attached to the electrode 12 by the wiring member 21 and the resin adhesive 22, and the pre-pressing portion 72 has a pressing member 63' The wiring member 21 and the solar battery cell 1 are pre-compressed by the pressurization by the pressing member 63 and the heating by the heating device 62. The main pressing portion 73 has a horizontal pressing member 64 on the lower surface, and is added to the resin adhesive 22 The upper pressure ruptures the conductive particles contained in the recording of the resin adhesive 22 to obtain conductivity. Further, 'the heating member 64a is disposed under the pressing member 64, and the heating device 62' is used to heat the resin. 22. The first heating unit 74 and the second heating unit 75 share a non-contact heating device 65 and heat the resin adhesive 22 to cure the non-contact heating device 65. For example, an IR (infrared) lamp, IH (induced heating), and heat are provided. Fig. 15 is a process diagram for pressing the wiring member 21 against the solar battery cell 1A, and the step S5 of Fig. 5 is shown in detail. First, the solar battery cell input device 70 is attached with a resin. In the solar battery cell 10 of the agent 22, the wiring material loading device 50 applies the wiring member 21 to the input portion of the wiring material pressing device 60 (step S21). More specifically, the solar battery cell input device 70 is a solar battery device. The unit 10 is placed on the wire 21 of the 201205854 that has been put into operation, and the wiring material input device 50 is used to put the wiring member 21 having the height difference on the solar battery cell 1A. The input unit 71 is used for the next process. The heating device 62 may preheat the resin adhesive 22. The time required for the process of the step S21 is, for example, 6 seconds. When the solar battery cell 10 and the wiring member 21 are put in, the transport device 6 (1) The solar battery cells 10 and the wiring member 21 are supplied to the pre-compression portion 72, and the solar battery cells 10 are continuously supplied to the input portion 71 at a ratio of one in six seconds. Next, in the case of the pre-compression portion 72, the heating device 62 is heated at a temperature lower than the softening temperature of the resin adhesive 22, and is heated at a temperature of 50 ° C to 90 ° C, for example, while being pressed. The member 63 pressurizes the wiring member 21 and the solar battery cell 10 to soften the resin adhesive 22 to pre-press the wiring member 21 and the solar battery cell 1 (step S22) because the same on the front and back surfaces of the solar battery cell 10. The position forming electrode 12 is preliminarily pressed by the wiring member 21 on both the front and back surfaces of the solar battery cell 10. Thereby, in the subsequent process, the wiring member 21 can be prevented from leaving the original position on the solar battery cell 1A. The time required for the process of step S22 is, for example, 3 seconds. The input process of the front solar battery cell 10 (step S21) is completed in 3 seconds because it takes 6 seconds, and the next solar battery cell 1 is not immediately transported from the input unit 71 to the pre-compression portion 72. Therefore, the preloading is completed in 3 seconds, and then standby for 3 seconds. After the preloading portion is held for a total of 6 seconds, the transport device 61 transports the solar battery unit 1 from the preloading portion 72 to the final pressing. 4 73 'At the same time, the second solar cell unit 21 201205854 is sent from the investment unit 71 to the pre-compression unit 72. In the case of the main pressing portion 73, the resin adhesive 22 is pressed by the pressing member 64 at about 2 to 3 MPa to be pressed. Thereby, the conductive particles contained in the resin binder 22 are broken to obtain conductivity. Further, the lower surface of the pressing member 64 is flat. Since the wiring member 21 is placed on the upper surface of the solar battery cell 10, the pressing member 64 does not come into contact with the solar battery cell 10 when the pressing member 64 is pressurized. Here, the pressurizing means 64a is provided at the lower portion of the pressurizing member 64, and it is not only pressurized, but also heated to harden the resin adhesive 22. The time required for the final pressing is '3 seconds, for example, the time required for the resin adhesive 22 to harden is, for example, 15 seconds. Therefore, it is assumed that the pressing member 64 and the pressing device 64a are used, and the pressing is performed. At the same time, the resin adhesive 22 is heated to completely harden, and it is necessary to heat for 15 seconds. As a result, this process becomes a bottleneck and reduces overall capacity. In other words, the takt time required for the completion of the pressing of the solar cell unit 1 from the solar cell unit 1 to the wiring material pressing device 6 to the wiring member 21 is 6 seconds (step S21). +6 seconds (step S22) + 15 seconds (heating for the final pressing and the resin adhesive 22 is completely hardened for 15 seconds) = 27 shift, and the calyx is required to heat the resin adhesive 22 by heating for 19 seconds. Therefore, the solar cell unit becomes one per minute (four per minute). Therefore, in the present embodiment, the longest time of the processes (steps S21 and S22 and the final pressing) is focused on step S21. For 6 seconds, the resin adhesive 22 is not completely cured in step S23, and is divided into a plurality of processes for hardening heating.

In the process, the resin is only heated for 3 seconds in the 15 seconds required for the hardening of the resin 2, and 'waits for 3 seconds in the formal pressing portion 73. After the clock, the first and second heating units 75 are transported to the first and second heating units 75, and the remaining ones are heated in two seconds, that is, in the i-th heating unit 74, by heating means and non-contact heating. The device 65 is added for the above temperature for (10) seconds (step s24). Further, it is transported to the second heating unit 75, and is similarly fined (step milk). The first and second heating units 74 and 75 are attached. In the second heating unit 75, the total pressing portion 73 and the heating time of the first heating unit 74 are combined and heated for a total of 15 seconds. Thereby, the time required for the hardening of the resin adhesive 22 is achieved, and the resin adhesive 22 is hardened. The wire is connected to the electrode 12 of the solar cell unit 1. In this case, the processes of steps S21 to S25 are all 6 seconds (steps S22 and S23 are combined with the standby time of 3 seconds for 6 seconds). The contact time is 6 seconds χ 5 (steps S21 to S25) = 3 〇 seconds, but the capacity can be improved to 1 ( 1 (10 per minute) of solar cells 1 〇. Also, the wiring material of Fig. 4 The pressing device 6 〇 does not perform hardening of the resin adhesive 22 after pre-pressing all the solar battery cells 10, because the size of the wiring material pressing device 6 ' is irrelevant for each solar battery cell 1 ' The number of the solar battery cells to be connected is approximately 5 pieces of the solar battery cells 1 of the inlet portion 71 to the second heating portion 75, which is the same as the "5J", and the wiring material of the present embodiment. The pressing device 6 is required to perform the heating process for hardening the resin adhesive 22 for a long time. Therefore, the solar cell string can be produced with high productivity. Also, since each solar cell unit 10 is hardened. The wiring material pressing device 6 can be miniaturized. The time of each step of the above-mentioned Fig. 15 is an example, and the curing of the resin adhesive 22 can be divided into a plurality of processes in accordance with the actual time. For example, the process of the step S21 In the case of 3 seconds, after heating for 3 seconds in step 823, the remaining 12 seconds are divided into 4 processes (that is, the first heating unit 74 is set to 3), and the throughput can be changed to 3 seconds. Further, for example, In the case where the time required for the process of step S22 is longer than the process of step S21, the heating time in each heating portion may be made smaller than the time required for the process in step S22. According to the above description, the additional effects or various modifications of the present invention are conceivable as long as they are the same, but the form of the present invention is not limited to the above embodiments.
