Description of the Invention: C. The present invention relates to a solar cell tandem manufacturing apparatus and a manufacturing method for connecting a plurality of solar battery cells by wiring materials to manufacture solar cells. An adhesive attaching device and an adhesive attaching method which are used in the solar cell tandem manufacturing apparatus and the manufacturing method, respectively. Background of the Invention Since the number of rounds 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 field energy battery array is an electrode formed on the light receiving surface of the solar battery cell, and is electrically connected to the electrode formed on the back surface of the adjacent solar battery cell by using the wiring material. In the past, a low-resistance material such as solder copper was used as a wiring material. However, since the wire rod coefficient of the wiring material is larger than the wire diameter of the semiconductor substrate of the solar cell unit such as the solar cell unit, the wiring material soldered to the solar cell unit is shrunk when it returns to normal temperature. The internal pressure creates pressure. As a result, there is a problem that the solar cell unit is warped. In recent years, this problem has been avoided by using a resin adhesive which is hardened at a temperature lower than the dissolution temperature of the solder (e.g., 13 generations of boots) to adhere the wiring member to the solar battery cell. More specifically, the solar cell 201205853 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 unit in the adhesive attaching device, and thereafter, the wiring is applied. The material pressing device applies the wiring member to the electrode to which the resin adhesive is attached. The adhesive attaching device has the following problems. In the solar cell, since the electrodes are formed on the light-receiving surface and the back surface, it is necessary to attach a resin adhesive to both surfaces thereof. In a general adhesive attaching apparatus, first, a resin adhesive is attached to the electrode on one side of the surface, and then a resin adhesive is attached to the other electrode. However, when the attachment is performed a plurality of times, the heat or pressure at the time of attachment may be applied to the solar cell, and the solar cell may be damaged. Moreover, the time required for attaching becomes longer, and there is a problem that the production capacity of the solar battery tandem manufacturing is lowered. Further, the wiring material pressing device has the following problems. In order to harden the resin binder, the wiring member and the electrode of the solar cell are pressed, and the non-heating time is longer than the time required for soldering (for example, 15 seconds). Therefore, Patent Document 1 discloses a method in which 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 resin which is a thermosetting resin adhesive is placed on the electrode on the light-receiving side of the solar cell unit, and a wiring material to which the adjacent solar cell unit is connected is disposed. Further, a wiring member adjacent to the other solar battery cell is placed on the electrode on the back side of the solar battery cell with the same resin adhesive interposed therebetween. (Process B). Next, the resin adhesive is heated to a temperature higher than the softening temperature of 201205853 and lower than the hardening temperature, and the wiring member is pre-compressed at each electrode of the cell unit. Yang Nengdian (Process C). Repeat the above process 8 and process b ” pre-pressed the electrodes in all solar cells. Bar wiring material (process D). – press the wiring material on the resin adhesive ~ The surface is larger than the hardening temperature of the resin adhesive, and the hardening is officially pressed. The heat is applied to the sun according to this method. After the temporary pressing, the resin adhesive attached to all the battery cells is hardened at the same time, and the sun is officially pressed. The resin adhesive hardening per one solar cell unit can be shorter: manufacturing a solar cell string. ' θ system However, in the method of Patent Document 1, there is a need to place all solar cells temporarily pressed in the process C. In the mounting table, there is a need for a device for pressing all the solar battery cells at the same time in the process D. As a result, the wiring material pressing device is increased in size, and there is a problem that the cost is increased.

狀的把持構件，在其間隙配置太陽能電池單元10的電極 12 ’藉由氣壓等把持太陽能電池單元10。 其次’運送滾輪471a〜474a、471b〜474b會旋轉，分別 對向於太陽能電池單元10的電極12之位置被供應附有剝離 紙之樹脂接著劑24(步驟S13)，同時為了以後被投入之太陽 能電池單元10 ’半切割部43a、43b會僅將附有剝離紙之樹 脂接著劑24的樹脂接著劑22，配合電極12的長度予以切割 (步驟S14)。亦即，在太陽能電池單元10的電極12，配合電 極12的長度切割之樹脂接著劑22會被供應。 此時’上面貼附部41a因為與電極12之數相同具有3個 供應捲筒42a，所以能依與所有太陽能電池單元1〇之表面側 的3個電極12對向的方式供應附有剝離紙之樹脂接著劑 24。關於太陽能電池單元1〇之背面側也是同樣。 其次，如以下，在太陽能電池單元10的電極12接著樹 脂接著劑22(步驟S15)。第10圖，係在太陽能電池單元1〇之 電極12接著樹脂接著劑22時的接著劑貼附裝置4〇之正視 圖。第11圖係第10圖之太陽能電池單元1〇附近的放大圖。 又，第12圖係把第1〇圖從紙面左側看的側視圖。第13圖係 第12圖之太陽能電池單元1〇附近的放大圖。此外，在第u 圖，係把太陽能電池單元投入裝置7〇省略。 首先’藉由氣缸(air cylinder)等，使上面貼附部41a的 壓著構件44a會下降，下面貼附部41b的壓著構件4朴會上 15 201205853 昇。藉此，如第10圖及第11圖所示，在太陽能電池單元10 之各電極12附有剝離紙之樹脂接著劑24會接觸。又，如第 11圖所示’在步驟814 ’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，對於在下面貼附部々ib 之壓著構件44b的表面為平坦’而在上面貼附部4ia之壓著 構件4知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為凹入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1〇之電極12接觸。 再者，壓著構件44a、44b，係約4、5秒間，一面夹著 上下的附有剝離紙之樹脂接著劑24及太陽能電池單元1〇之 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50°C~9(TC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10之負荷，而 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Sl6)。第 16 201205853 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貼附在太陽能電池單元10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 到第2加熱部75之各部，係在運送裝置61上，佔有大約太陽 能電池單元10之1片分的空間。 17 201205853 運送裝置61係把太陽能電池單元10從投入部71至第2 加熱部75之順序，每在各階段處理結束時，運送至下一個 階段。加熱裝置62係把太陽能電池單元10予以加熱。加熱 裝置62,係在從投入部71至第2加熱部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。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10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之鎳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 單兀投入裝置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6G的投人部（步驟S21)。更具體的，係太陽能電池 單兀投入裝置7〇係把太陽能電池單元1〇投入已被投入之配 線材21之上’配線材投人裝置5G係把設有高低差之配線材 21杈入在太陽能電池單元1〇之上。投入部了丨，係為了其次 18 201205853 • 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 運送至預壓著部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 W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— 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10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 ’也單元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 知，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， 運迗裝置61把太陽能電池單元10從預壓著部72運送到正式 °著。卩73，同時從投入部7〗把其次的太陽能電池單元1 〇運 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 201205853 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1〇的上面 被載置有配線材21，以加屋構件64加壓之際，加壓構件64 不會與太陽能電池單元1〇有所接觸。 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接觸 時間扣<^丨11^)，為6秒(步驟821)+6秒(步驟822)+15秒(為了 正式壓著及使樹脂接著劑2 2完全硬化的加熱15秒鐘2 7 秒，產此’係因為使樹脂接著劑22硬化的加熱需花15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。 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823 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。 首先，在步驟S23，把樹脂接著劑22加壓與要正式壓著 並行’藉由加熱裝置62及加熱裝置64a ’較樹脂接著劑22之 20 201205853 *! 魏溫度更高的溫度，例如以13 〇 t〜18 G t：予以加熱樹脂接 著劑22(步驟s23)。在本製程，樹脂接著劑η之硬化所需要 的15秒鐘之中，僅加熱3秒鐘。 而且，在正式壓著部73待機3秒鐘之後，運送到第1加 熱部74，在第1及第2加熱部75，把剩餘的12秒鐘分成2次予 以加熱。即，在第1加熱部74方面，藉由加熱裝置a及非接 觸加熱裝置65，以上述溫度予以加熱6秒鐘（步驟S24)。再 者’運送到第2加熱部75，同樣地予以加熱6秒鐘（步驟S25)。 第1及第2加熱部74、75係共有非接觸加熱裝置65，可同時 加熱2片的太％能電池單元1〇。 在第2加熱部75，正式壓著部73與在第1加熱部74之加 ' 熱時間合起來合計被加熱15秒鐘。藉由此，達到樹脂接著 ， 劑22之硬化所需要的時間，樹脂接著劑22硬化，配線材21 與太陽能電池單元10之電極12會被接著。 如此作時，步驟S21〜S25之製程全部都成為6秒（步驟 S22、S23係與待機時間之3秒合起來為6秒）。因此接觸時 間，係成為6秒χ5(步驟S21〜S25)=3〇秒，但產能可改善為6 秒1個(每分10個）的太陽能電池單元10。 又，第4圖之配線材壓著裝置60，並不是把所有的太陽 能電池單元10預壓著後執行樹脂接著劑22的硬化，因為依 每一個太陽能電池單元1〇進行，配線材壓著裝置6〇的大 小，係無關欲連接之太陽能電池單元1〇之數目，對應於投 入部71〜第2加熱部75之太陽能電池單元10的5片分左右即 "SfJ" 〇 21 201205853 如此，在本實施形態之配線材壓著裝置6〇，需要最長 時間之使樹脂接著劑22硬化之加熱製程分成複數進行。因 此，以高的產能可產生太陽能電池串列。又，因為對每一 個太陽能電池單元1〇進行硬化，可使配線材壓著裝置6〇小 型化。 上述第15圖之各步驟的時間為舉例表示，配合實際的 時間，將樹脂接著劑22之硬化分成複數的製程即可。例如， 步驟S21的製程為3秒的情況，在步驟S23加熱3秒鐘之後， 把剩餘的12秒鐘分成4製程（即，把第丨加熱部74設置3個）， 產旎可變成3秒1個。又，例如，在步驟S22的製程所要_ 間較步驟S21的製程長的情況’把在各加熱部的加熱時間成 為小於在步驟S22之製程所要的時間之方式即可。 根據上述之記載，只要是同業者，或可想到本發明之 ，加效果《種變形，但本發明之形態，並不受上述各個 實施形態之限制。在專财請範圍被規定之内容及從其同

Embodiments for carrying out the invention. Hereinafter, a solar cell tandem manufacturing apparatus and manufacturing method, an adhesive attaching apparatus, an adhesive attaching method, and a wiring material pressing apparatus according to the present invention will be specifically described with reference to the drawings. And an embodiment in which the wiring material is pressed against the pressing method. First, the solar battery cell 10 used in the present embodiment and the solar battery string 20 manufactured in the present embodiment will be described. Fig. 1 is a plan view showing the light-receiving surface side of the solar battery cell 10 used in the present embodiment. The solar battery cell 10 is, for example, a polycrystalline stone, and is formed by the internal n-type region and the p pear region. The size and thickness are, for example, 125 mm ><125 mm and 0.2 mm, respectively. A plurality of finger electrodes 11 are formed on the solar cell unit 10, and a plurality of bus electrodes 12 are formed orthogonally thereto. The solar battery cell 10' is formed with a finger electrode 1A and a bus electrode 12 on the surface (first main surface) of the received sunlight as shown. Further, only the bus electrode 12 is formed on the back surface (second main surface)'. In the present embodiment, the example in which the three bus electrodes 12 are formed is shown. However, the number of the bus electrodes 12 may be limited to three or two, and the number of the bus electrodes 12 corresponding to the size of the solar cell single t1 IG may be formed. When the light receiving surface of the solar month t* battery single tlIO receives sunlight, the light generates a carrier (_^), which means that a shirt and a hole are generated. The finger electrode 11 collects light generated on the light receiving surface to generate a carrier. The bus electrode (10) is collected by a light-generating carrier collected by the counter electrode u 201205853. Fig. 2 is a side view of the solar cell string 20 manufactured by the manufacturing apparatus of the present embodiment. Figure 3 is a top view thereof. The solar cell string 20' includes a finger electrode "and a plurality of solar cells 10 formed by the bus electrode 12, a wiring member 21, and a resin adhesive 22. A plurality of solar cells 1 and a bus electrode 12 parallel directions are arranged in a row. The length of one wiring member 21 is about twice the direction in which the bus electrode 12 of the solar battery cell 10 is formed, and a height difference is provided in the center thereof. The wiring member 21 is sandwiched between the height and the low. The solar battery cell 10 is disposed on the upper side of the one end side, and the solar battery cell 10 is disposed on the lower side adjacent to the other end side. Further, the wiring member 21 connects the two solar battery cells 10. More specifically, each wiring material is 21, one of the bus electrodes 12 formed on the surface of the solar cell 10 is electrically connected to one of the bus electrodes 2 formed on the back surface of the solar cell 10. Resin adhesive 2 2 is interposed between the bus electrode 12 and the wiring member 21, and these are bonded. The resin adhesive 22 is, for example, thermally hardened as a conductive particle containing nickel particles. In the epoxy resin, the pressure-sensitive resin adhesive 22 causes the conductive particles to be broken, and the resin adhesive 22 becomes electrically conductive. Further, the resin adhesive 22 is softened, for example, when heated at 50 ° C to 90 ° C. It is hardened when heated at 130 to 180 ° C lower than the melting temperature of solder. The solar cell string 20 of Fig. 2 is passed through a filling material such as EVA (ethylene vinyl acetate) to glass. The cover sealer is a solar battery module. Fig. 4 is a side view of a solar cell tandem manufacturing apparatus (hereinafter, manufacturing apparatus 10 201205853) 100. The manufacturing apparatus of Fig. 4 includes an inspection apparatus 30 and a subsequent agent. The attaching device 40, the wiring material loading device 50, the wiring material pressing device 60, and the solar battery cell charging device 70. The manufacturing device 100 of the same figure uses the solar battery cell 10 of Fig. 1 to manufacture the solar battery string of Fig. 2 The inspection device 30 checks whether the solar battery cell 10 has a shape such as a crack, and the solar battery cell input device 70 can hold the solar battery unit 1 at the correct position. The position adjustment is performed in the manner of 0. 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 material input device 50 is attached to the wiring member 21. The wiring height pressing device 60 is placed in the wiring material pressing device 60. The wiring material pressing device 60 pressurizes and heats the resin adhesive 22, and then presses the wiring member 21 against the bus electrode 12 of the solar battery cell 10. The unit loading device 70 sucks the solar battery cells 10 by air pressure or the like, and respectively inspects the solar battery cells 10 after inspection to the adhesive attaching device 40, and directs the solar battery cells 10 to which the adhesive is attached toward the wiring materials. The crimping device 60 is put in. Fig. 5 is a manufacturing process diagram of the solar cell string 20. First, the inspection device 30 performs inspection of the solar battery cell 10 (step S1), and if the inspection is not confirmed to be abnormal, the solar battery cell input device 70 takes out the inspected solar battery unit 10 from the inspection device 30, and sticks it toward the adhesive. The attachment device 40 is put in. Then, the adhesive attaching device 40 attaches the resin adhesive 22 to the bus electrode 12 of the solar battery cell 10 (step S2). The details of the adhesive attaching device 11 201205853 40 will be described later, but the adhesive attaching device 4Q is formed by forming three bus electrodes η on the front and back surfaces of the solar cell unit 1 respectively. The agent η can reduce the load on the solar cell single τ ϋΐ based on heat or pressure 'and can be attached in a short time. Next, the wiring member input device 50 is provided with the wiring member 21 in which three steps of the height difference are placed in the wiring member pressing device 6 (step S3). In this case, the wiring member 21 is placed on each of the bus electrodes 12 on the front surface side of the solar battery cell 1G of the wiring material pressing device 6G. Investing. In addition, the solar battery unit 1 is placed on the other end of the wiring member 21 to be placed in the wiring material pressing device 6 (step S4). At this time, the solar cell unit 1' is connected to the bus electrode 12 on the back side of the solar cell unit 1 so as to be placed on each of the wiring members 21, and then the wiring material pressing device 6 is used to resin The subsequent agent 22 is pressurized and heated, and the wiring member 21 is pressed against the bus electrode 12 of the solar battery cell 1A (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 performs the process of dividing the heating into a plurality of processes, so that the throughput can be improved. Further, since each of the solar battery cells 10 is pressed, the wiring material pressing device 60 can be miniaturized. Hereinafter, the adhesive attaching device 40 according to the first feature of the present embodiment will be described in detail. Fig. 6 is a front view of the adhesive attaching device 40, and Fig. 7 is a side view of Fig. 6 201205853 as seen from the left side of the paper. The adhesive attaching device 4 is provided with an upper attaching portion "" and a lower attaching portion 41b. The surface attachment portion 4ia is attached to the bus electrode 12 (hereinafter, simply referred to as the electrode 12) on the surface side of the solar cell unit 1 贴, and the resin adhesive 22' is attached to the lower surface of the solar cell unit 10 A resin adhesive 22 is attached to the electrode 12 on the moon side. The upper attaching portion 41a' has three supply reels 42a, a half-cut portion 43a, a pressing member 44a, a peeling roller 45a, three recovery reels, and transport rollers 471a to 474a. The three supply reels 42a are placed at an interval of the electrodes of the solar battery cells. Each of the supply reels 42a is placed around a strip-shaped resin adhesive 22 (hereinafter referred to as a resin adhesive 24 to which a release paper is attached) to which the release paper 23 is attached. When the transport roller (first transport roller) 471a rotates, the resin adhesive 24 with the release paper is pulled out from the supply reel 42a and supplied to the half-cut portion 43a. Further, the resin adhesive 24 to which the release paper is attached is provided with a resin adhesive 22 on the outer side of the upper attachment portion 41a and a release paper 23 on the inner side. The half-cut portion 4 3 a ' is cut only by the length of the electrode 12 of the resin adhesive 24 with the release paper. The transport roller (second transport roller) 472a is rotated, and the resin adhesive 24 with the release paper is supplied from the half-cut portion 43a to the opposite position to the electrode 丨2 of the solar battery cell. In the pressing member 44a, the resin adhesive 24 with the release paper is pressed and heated on the electrode 12 on the surface side of the solar battery cell 10, and the resin adhesive 22 and the electrode 12 are pressed. The stripping roller 45& strips the release paper 23 from the resin-attached agent 24 to which the release paper is attached. The take-up reel 46a is recovered by the transport roller 13 201205853 473a, 474a when it is rotated. In addition, in the seventh embodiment, three resin adhesives 24 with release paper are transported by three transport rollers 471a, but three resin adhesives 24 with release paper are transported by one transport roller 471a. can. Further, in the same figure, three resin adhesives 24 with release paper are cut by the "solid half-cut portion 43a", but one of the three half-cut portions 4 3 a may be cut by one resin adhesive 2 2 . The structure of the attaching portion 41b is substantially the same as that of the attaching portion 41a. In Figs. 6 and 7, the structural members of the attaching portion 41b are attached with the symbol "b". However, as shown in Fig. 7, the pressing member 44b and the pressing member 44a are different in shape. The reason for this is that the solar battery cell input device 7 is configured to hold the solar cell unit 10, and the pressing member 44a can avoid the solar cell unit input device 70 by forming the unevenness of the pressing member 44a of the upper attaching portion 41a. The resin adhesive 22 and the electrode 12 are pressed. The pressing member (first pressing member) 44a and the pressing member (second pressing member) 44b constitute a pressing portion. Further, the transport rollers 473a, 47, 47, 47, and the recovery reels 46a, 46b constitute a recovery portion. Fig. 8 is a process diagram for attaching the resin agent 22 to the electrode 12 of the solar cell unit 1 to show the step § 2 of Fig. 5 in detail. First, the resin adhesive 24 with the release paper attached is placed in advance on the supply reel, 42b (step SU). Next, the solar cell unit ί 会 is put into the adhesive attaching device 40 (step S12). More specifically, the solar cell unit hitting device 7' holds the solar cell unit 1 between the attaching portion and the lower attaching portion 41b. Fig. 9 is a plan view of the solar battery unit ι held by the solar cell 14 201205853 battery unit input device 70. As shown in the figure, the tip end portion of the solar battery cell input device 7 has a fork-shaped holding member, and the electrode 12' of the solar battery cell 10 is disposed between the gaps to hold the solar battery cell 10 by air pressure or the like. Next, the 'transport rollers 471a to 474a and 471b to 474b are rotated, and the resin adhesive 24 to which the release paper is attached is supplied to the position of the electrode 12 of the solar battery cell 10 (step S13), and the solar energy is put in for the future. The battery unit 10' half-cut portions 43a and 43b cut only the resin adhesive 22 to which the resin adhesive 24 of the release paper is attached, and the length of the electrode 12 is cut (step S14). That is, at the electrode 12 of the solar cell unit 10, the resin adhesive 22 cut in accordance with the length of the electrode 12 is supplied. At this time, since the upper attaching portion 41a has three supply reels 42a as the number of the electrodes 12, it can be supplied with the release paper in such a manner as to oppose the three electrodes 12 on the surface side of all the solar battery cells 1〇. Resin adhesive 24. The same applies to the back side of the solar battery cell 1 . Next, as follows, the electrode 12 of the solar battery cell 10 is followed by the resin adhesive 22 (step S15). Fig. 10 is a front elevational view showing the adhesive attaching device 4 when the electrode 12 of the solar cell unit 1 is followed by the resin adhesive 22. Fig. 11 is an enlarged view of the vicinity of the solar cell unit 1 of Fig. 10. Further, Fig. 12 is a side view showing the first plan view from the left side of the paper. Fig. 13 is an enlarged view of the vicinity of the solar cell unit 1 of Fig. 12. Further, in the drawing u, the solar battery unit is put into the device 7 and omitted. First, the crimping member 44a of the upper attaching portion 41a is lowered by an air cylinder or the like, and the pressing member 4 of the lower attaching portion 41b is lifted by 15 201205853 liters. Thereby, as shown in Figs. 10 and 11, the resin adhesive 24 to which the release paper is attached to each electrode 12 of the solar battery cell 10 is brought into contact. Further, as shown in Fig. 11, 'the resin adhesive 22 is cut at the step 814' to match the length of the electrode 12. Here, as shown in Fig. 12 and Fig. 13, the surface of the pressing member 44b of the attaching portion 々ib is flat, and the surface of the pressing member 4 of the upper attaching portion 4ia is formed. It is bump. This is because the solar cell input device 70 of the upper side of the solar cell unit 1 is held. That is, the pressing member 44a is a recessed portion that avoids the grip portion of the tip end of the solar battery cell input device 7b, and the resin adhesive 24 with the release paper is brought into contact with the electrode 12 of the solar cell unit 1A. 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 1 for about 4 and 5 seconds, while the resin adhesive 22 is pressed. The softening temperature is higher than the curing temperature, for example, heating at 50 ° C to 9 (TC), whereby the resin adhesive 22 is softened and attached to the electrode 12 of the solar cell unit 1 . The pressing member 44a of the attachment portion 41a is raised, and the pressing member 44b of the lower attachment portion 41b is lowered. As shown in Figs. 10 to 13, since the resin with the release paper is simultaneously attached to all the electrodes 12 The agent 24 is pressurized and heated, and as long as the process of the step S15 of Fig. 8 is once performed, the adhesive can be attached to all of the electrodes 12. Therefore, the load on the solar battery unit 10 based on heat or pressure is reduced, and 'can be short Next, the release paper 23 is peeled off from the resin adhesive 22 (step S16). The 16th 201205853 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 roller 45a is pulled by a cylinder or the like. 45b—the surface is moved above and below the solar cell unit 10, and the release paper 23 is pulled from both sides by a chuck (not shown), and the resin adhesive 22 attached to the electrode 12 of the solar cell is peeled off. The paper 23 is peeled off. At the end of the stripping, the stripping rollers 45a, 45b return to the original position as shown in Fig. 6. The stripped paper 23 which is peeled off is rotated by the transport rollers 473a, 474a, 473b, 474b. Then, the retracting reels 46a and 46b are taken up. Thereafter, the solar battery cells 10 are taken out from the attaching device by the solar battery cell input device 70 (step S17). By the above, the resin adhesive 22 can be attached. In the adhesive attaching device 40 of the present embodiment, only the same number of resin adhesives 24 with release paper attached to the electrode 12 of the solar battery cell 10 are used, from the solar battery cell. The surface side and the back side of 10 are sandwiched and pressurized and heated. Therefore, all of the electrodes 12 can be attached with the resin adhesive 22 at the same time, the load on the solar battery cell 10 can be reduced, and the adhesive resin adhesive 22 can be shortened. Next, the wiring material pressing device 60 according to the second feature of the present embodiment will be described in detail. The wiring material pressing device 60 of Fig. 4 includes an input portion 71, a pre-compression portion 72, and a final pressing. The transport unit 61 and the heating device 62 that are used in common by the respective portions 73, the first heating unit 74, the second heating unit 75, and the like, are provided on the transport unit 61 from the input unit 71 to the second heating unit 75. It occupies approximately one space of the solar battery cell 10. 17 201205853 The transport device 61 transports the solar battery cells 10 from the input unit 71 to the second heating unit 75 in the order of the end of each stage, and then transports to the next stage. . The heating device 62 heats the solar battery cells 10. The heating device 62 is capable of heating the solar battery cells 1 at different temperatures from the respective portions from the input portion 71 to the second heating portion 75. In the input unit 71, the wiring member 21 and the resin adhesive 22 are attached to the solar battery cell 10 of the electrode 12. The pre-crimping portion 72 has a pressing member 63' which is pre-stressed by the wiring member 21 and the solar battery cell 10 by pressurization based on the pressing member 63 and heating by the heating means 62. The main pressing portion 73 has a horizontal pressing member 64 underneath, and the conductive adhesive is applied to the resin adhesive 22 to rupture the conductive particles such as nickel contained in the resin adhesive 22 to obtain conductivity. Further, a heating device 64a is provided under the pressing member 64, and the heating device 62 is fitted to heat the resin adhesive 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 it. The non-contact heating device 65 is, for example, an IR (infrared) lamp, IH (induced heating), hot air or the like. Fig. 15 is a plan view showing the step S5 of Fig. 5 in order to press the wiring member 21 against the solar cell unit 1'. First, the solar cell unit 100 is placed in the solar cell unit 10' to which the resin adhesive 22 is attached, and the wiring member 21 is placed in the input unit of the wiring material pressing device 6G (step S21). ). More specifically, the solar cell unit 兀 兀 把 把 太阳能 太阳能 太阳能 太阳能 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The solar cell unit is above the top. It is also possible to preheat the resin adhesive 22 using the heating device 62 for the next step of the process of 2012-05853. The time required for the process of step S21 is, for example, 6 seconds. When the solar battery unit 10 and the wiring member 21 are loaded, the transport device 61 transports the battery unit 10 to the pre-compression portion 72, and the next solar battery unit 10 and the wiring member 21 are loaded. That is, the solar battery cells W are continuously supplied to the input unit 71 at a ratio of one piece in 6 seconds. Next, in 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 lower than the curing temperature, for example, the surface is heated at 50 ° C to 90 ° C while The pressing member 63 pressurizes the wiring member 21 and the solar battery cell 10, and softens the resin adhesive 22 to pre-press the wiring member 21 and the solar battery cell 10 (step S22). Since the electrode 12 is formed at the same position on the front surface and the back surface of the solar battery cell 10, the solar power is also preliminarily pressed by the wiring member 21 on both the front and back surfaces of the unit 10. By this, 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. In the input process of the front solar battery cell 10 (step S21), the process is completed in 3 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 pre-compression is completed in 3 seconds, and then standby for 3 seconds, and after the pre-compression portion is held for a total of 6 seconds, the transport device 61 transports the solar battery unit 10 from the pre-compression portion 72 to the final temperature. . At the same time, the next solar cell unit 1 is transported from the input unit 7 to the pre-compression unit 72. In the case of the main crimping portion 73, the 201205853 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 1A, the pressing member 64 does not come into contact with the solar battery cell 1 when the addition 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, for example, 3 seconds, and the time required for the resin adhesive 22 to harden is, for example, 15 seconds. Therefore, it is assumed that the pressurizing member 64 and the pressurizing means 64a are required to heat the resin adhesive 22 to be completely cured simultaneously with the final pressing, and it is necessary to heat for 15 seconds. As a result, this process becomes a bottleneck and the overall capacity is reduced. That is, the contact 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 <^丨11^), which is 6 seconds ( Step 821) + 6 seconds (step 822) + 15 seconds (heating for 15 seconds and 27 seconds for the final pressing and the resin adhesive 2 2 is completely hardened), because of the heating required to harden the resin adhesive 22 After spending 15 seconds, it becomes 1 solar cell unit per minute (4 per minute). Therefore, in the present embodiment, the longest time of the process (steps S21 and S22 and the final pressing) is Focusing on the 6 seconds of the step S21, the resin adhesive 22 is not completely cured in step 823, and is divided into a plurality of processes for the heating of the hardening. First, in step S23, the resin adhesive 22 is pressurized in parallel with the pressing. 'By heating device 62 and heating device 64a' is 20 more than resin adhesive 22 201205853 *! The temperature is higher, for example, 13 〇t~18 G t: heating resin adhesive 22 (step s23). This process, 15 seconds required for the hardening of the resin adhesive η In the case where the main pressing portion 73 stands by for 3 seconds, it is transported to the first heating unit 74, and the remaining 12 seconds are divided into two in the first and second heating units 75. That is, in the first heating unit 74, the heating device a and the non-contact heating device 65 are heated at the above temperature for 6 seconds (step S24). Further, the second heating unit 75 is transported to the second heating unit 75. Heating is performed for 6 seconds (step S25). The first and second heating units 74 and 75 share the non-contact heating device 65, and can simultaneously heat two sheets of the solar cell unit 1〇. In the second heating unit 75, the second heating unit 75 is officially heated. The pressing portion 73 is heated for a total of 15 seconds in combination with the heating time of the first heating portion 74. Thereby, the resin is cured, and the resin adhesive 22 is hardened, and the wiring material is hardened. 21 and the electrode 12 of the solar cell unit 10 are followed. 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). , is 6 seconds χ 5 (steps S21 to S25) = 3 〇 seconds, but the productivity can be improved to 6 seconds 1 (10 per minute) of the solar cell unit 10. Further, in the wiring material pressing device 60 of Fig. 4, not all of the solar battery cells 10 are pre-compressed, and the resin adhesive 22 is hardened, because each one The solar cell unit 1 is formed, and the size of the wiring material pressing device 6 is the number of solar battery cells 1 to be connected, and the number of the solar battery cells 10 corresponding to the input unit 71 to the second heating unit 75 is 5 pieces. In the wiring material pressing device 6 of the present embodiment, the heating process for curing the resin adhesive 22 for the longest time is divided into a plurality of steps. Therefore, solar cell strings can be produced with high productivity. Further, since each of the solar battery cells 1 is hardened, the wiring material pressing device 6 can be downsized. The time of each step of the above Fig. 15 is exemplified, and the hardening of the resin adhesive 22 can be divided into a plurality of processes in accordance with the actual time. For example, if the process of step S21 is 3 seconds, after heating for 3 seconds in step S23, the remaining 12 seconds are divided into 4 processes (that is, 3 sets of the third heating unit 74 are set), and the calving can be changed to 3 seconds. One. Further, for example, in the case where 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, it is conceivable that the present invention can be applied to the present invention, and the effect of the present invention is not limited by the above embodiments. It is possible to add, change, or delete parts of the scope of the invention and the scope of the concept and the meaning of the invention.
