200832787 九、發明說明 【發明所屬之技術領域】 本發明，係關於例如在電池的製造工序中收納電池的 電池托盤，關於用一個托盤就可收納厚度不同的多種電池 之電池托盤及使用該電池托盤的電池之製造方法。 • 【先前技術】 • 在電池的製造工序中，有在將電池收納於托盤中的狀 態下進行處理的工序。並且，在製造工序間之收授和保管 方面也使用托盤。在專利文獻1、2 (專利文獻1 :日本特 開2 00 0 — 53 1 82號公報、專利文獻2 :日本特開2002 — 3 62 5 66號公報）中，提案有實現輕量化同時可確保必要強 度的電池托盤。 另外，在電池的化合（充電）工序中，在將多數個霞 池收納於托盤中的狀態下，以在電池的上下端子上壓接電 • 極的狀態下進行充電。在該情況，需要確保電池的上下端 ， 子與電極之間的位置精度而進行可靠的充電。 於圖2 0 ( a )，顯示以往的電池托盤之一例的俯視圖 。該圖係顯示方形電池用的托盤之例子。在四方形的電池 托盤1 00上設有多數個電池收納部1 0 1。圖20 ( b )，係 顯示電池收納部1 〇 1的一個份之放大圖。該圖，係顯示收 納方形電池1 02 (斜線部）後的狀態。 電池收納部1 〇 1的兩端部1 03係將寬度變窄，在該部 分卡合方形電池1 〇 2的兩端部。藉此，可將方形電池1 〇 2 200832787 穩定地載置於電池收納部101內。因此，在化合工序中， 可確保方形電池102的上下端子、與充電用的上下電極之 位置關係的精度，而能確實地完成充電。 【發明內容】 [發明所欲解決之問題] 然而，如圖20所示的電池托盤1 00，係如上所述地， 9 將電池收納部101的兩端部103之寬度作成符合方形電池 1 02的厚度之設計。因此，對於厚度不同的每種方形電池 都必須準備專用的托盤。在該情況下，成形托盤的模具也 是每種托盤專用的，在成本上不利。更且，在製造工序中 ，需要根據方形電池的厚度來變換所對應的托盤，在生産 效率方面也不利。另外，在上述之專利文獻1、2中，對 於可收納多種電池的構造並沒有提出特別方案。 本發明係用以解決如上述之以往的問題，其目的在於 # 提供一種用一個托盤就可收納厚度或外徑不同的多種電池 . 之電池托盤。 [用以解決問題之手段] 爲達成上述目的，本發明的電池托盤，係一種收納電 池的電池托盤，其特徵爲：具備有：開口；及設在上述開 口的裏側之收納部；以及設在上述收納部的內部之傾斜部 ，相對向的上述傾斜部彼此之間隔，係隨著朝向上述開口 而變寬，上述電池係可在被上述開口包圍且與上述傾斜部 -6- 200832787 抵接的狀態下收納於上述收納部內。 [發明之效果] 根據本發明，用一個托盤就可收納厚度或外徑不同的 多種之電池。 【實施方式】 • [發明之實施形態] 本發明的電池托盤，係由於具備有隨著朝向開口而相 對向部彼此的間隔變寬之傾斜部，因此即使是厚度或外徑· 不同的電池，也可以改變載置位置的高度而載置於溝槽上 ，且用一個托盤就可收納厚度或外徑不同的多種之電池。 在上述本發明的電池托盤中，上述電池托盤係收納圓 筒形的電池之電池托盤，上述傾斜部係形成爲至少用3點 來支撐上述圓筒形的電池之底部爲較理想。該結構，係適 • 用於外徑不同的圓筒形電池之收納。 ， 又，上述傾斜部，係包含相對向的傾斜面之溝槽，且 上述相對向的傾斜面彼此之間隔，係隨著朝向上述開口而 變寬爲較理想。該結構，係適用於厚度不同的方形電池之 收納。 又，在從相對向於上述開口的一側觀察上述電池的收 納狀態時，上述開口，係包含限制上述電池之寬度方向的 移動之限制面爲較理想。根據該結構，由於可限制電池之 寬度方向的移動，因此在寬度方向上可穩定地收納電池。 200832787 又，在從相對向於上述開口的一側觀察上述電池的收 納狀態時，上述開口，係在上述電池的一對對角位置，具 有限制上述電池的旋轉移動之限制面爲較理想。根據該結 構，即使將收納的電池之厚度變大，也可以在與限制旋轉 移動的限制面相反之一側，根據厚度的增加量在旋轉移動 後的狀態下，保持穩定的直立狀態。 ^ 又，限制上述寬度方向的移動之限制面、與限制上述 ^ 旋轉移動之限制面以鈍角相交爲較理想。 又，在使上述電池直立於上述溝槽上時，使其中一方 的上述傾斜面與上述電池之間的距離比另一方的上述傾斜. 面與上述電池之間的距離較爲小地，配置上述相對向之傾 斜面爲較理想。根據該結構，可減小在收納厚度大的方形 電池時的晃動，可實現穩定的收納。 又，上述開口的內周面與上述收納部的內周面係處於 同一平面上爲較理想。根據該結構，托盤之一體成形則變 • 得容易。 、 又，上述開口係形成多數個開口列，並將上述各開口 列彼此平行地配置爲較理想。 又，上述電池托盤，係組合形成有上述溝槽之第一托 盤、和形成有上述開口的第二托盤的構造爲較理想。根據 該結構，樹脂成形托盤的情況之模具的構造變得簡單。 上述第二托盤，係可以更換爲較理想。根據該結構， 由於第一托盤係一邊共用，一邊將第二托盤更換爲改變了 開口形狀的托盤，藉此可以擴大可收納的電池的厚度之範 -8- 200832787 圍。 又，上述開口，係在與上述收納部相反的一側形成錐 形面爲較理想。根據該結構，電池的收納變得容易。 又，在上述收納部的內部形成貫通孔，並可用通過上 述貫通孔的電極、和上述開口側的電極夾緊收納於上述收 納部內的電池爲較理想。根據該結構，可將電池托盤使用 於化合工序。 Φ 以下，參照附圖對本發明的一實施形態進行說明。 (實施形態1 ) 圖1，係顯示本發明的一實施形態之上下電池托盤中 的下托盤之圖。圖1(a)係俯視圖，圖1(b)係側視圖 。在下托盤1上，設有多數個電池收納部2，在各電池收 納部2內可以各收納一個方形電池。 圖2係顯示電池收納部2的放大圖。圖2 ( a )係俯視 # 圖，圖2(b)係圖2(a)的A— A線之剖面圖。雖然在圖 . 1中電池收納部2被傾斜配置，但是在圖2中爲了容易理 解而垂直地圖示。另外’以兩點虛線顯示收納時的方形電 池5 〇 在圖2 ( a )中，在電池收納部2的寬度方向（箭頭記 號a方向）之兩端部，以隔著貫通孔4的方式形成有作爲 傾斜部的溝槽3。在本實施形態中，在貫通孔4的形成部 分並無形成溝槽3。因此，圖2(b)的溝槽3，在圖2(a )的圖示中，係顯示隔著貫通孔4的溝槽3中之上側的溝 -9- 200832787 槽3。 另外，在後面的實施形態2中，亦可爲如圖13所示 的下托盤之收納部21地，不分割溝槽而在溝槽上形成貫 通孔之結構。 溝槽3，係如圖2 ( b )所示，形成於電池收納部2的 裏側（底面側），將相對向的傾斜面3a和傾斜面3b形成 “ 爲V字形。傾斜面3a、3b，係形成使傾斜面3a與傾斜面 φ 3b的間隔隨著朝向下托盤1的表面側而變寬。將方形電池 5的底面載置於溝槽3上，藉由溝槽3決定方形電池5的 高度方向（箭頭記號b方向）之位置。 另外，雖然溝槽3係以V字狀的例子來圖示，但方形 電池5不抵接之溝槽3的底部也可以形成爲曲面狀，也可 以包含水平面。又，對於方形電池5抵接的傾斜面，也可 以考慮包含曲面的結構。即，溝槽3的剖面形狀，並非限 於完全的V字狀，只要包含使相對向的傾斜面3a與傾斜 • 面3b的間隔變寬地形成之部分即可。 . 在各電池收納部2上，設置貫通孔4。如圖2 ( b )所 不，貫通孔4係形成使貫通下托盤1的底面。在化合工序 中，可使電極通過貫通孔4，將該電極和從上側降下的另 ~個電極壓接於方形電池5的上下端子部，而對方形電池 5進行充電。充電的詳細係於後具體地說明之。 圖3，係顯示上托盤之圖。圖3 ( a )係俯視圖，圖3 (b )係側視圖。上托盤6，係在平板狀構件上形成多數個 開口 7。在將圖1的下托盤1和圖3的上托盤6組合後時 -10 -

200832787 12、1 3限制位置。因此，錐形面14係至4 各面上即可。 圖5，係將上托盤6和下托盤1組合f 圖5(a)係俯視圖，圖5(b)係側視圖。 示，在下托盤1的上側具有上托盤6，在圖 中，在上托盤6的開口 7之下側具有電池收 ~ 圖6 ( a)，係顯示圖5 ( a)的開口 7 • 。圖6(b)係圖6(a)的C— C線之剖面 )中，開口 7部分係被傾斜配置，但在圖6 易理解而垂直地圖示。另外，以兩點虛線羅 形電池5。 一個電池收納部2的一個份對應於開口 若從開口 7的上側***方形電池5，則方形 會與溝槽3的傾斜面3a、3b抵接，且方形 開口 7包圍的狀態收納於電池收納部2內。 • 在本實施形態中，將電池托盤分割成上 、 盤1而構成。根據這種結構，在進行樹脂域 構造則變得簡單。另外，上下托盤的定位， (pin )與定位孔嵌合來進行。在進行樹脂 位銷和定位孔一體成形即可。 其次，說明電池的化合工序。圖7 ( a ) 池5收納於電池收納部2的狀態之俯視圖。 c )係圖7 ( a)的D — D線之剖面圖，圖7 電前的狀態，圖7 ( c )係顯示充電時的狀] >設置在此等之 t的狀態之圖。 如圖5 ( b )所 5 ( a )的圖示 納部2。 部分之放大圖 圖。在圖5 ( a (a )中爲了容 丨示收納時的方 7的一個份。 電池5的底面 電池5係以被 托盤6和下托 ^形時的模具之 係可使定位銷 成形時，將定 ，係將方形電 圖 7 ( b )、( (b )係顯示充 態、。如圖7 ( a -12- 200832787 )所示，在收納方形電池5時，方形電池5係被開口 7包 圍，且如圖7(b)所示，方形電池5係以與溝槽3的傾斜 面3a、3b抵接的狀態收納在收納部2內。 如圖7 ( b )所示，在化合工序中，在方形電池5的上 下分別具有上側電極1 5、下側電極1 6。充電時上側電極 1 5係會下降，並以靠近方形電池5的正極端子1 7之方式 移動。下側電極16係會上升並通過貫通孔4內而以靠近 • 方形電池5的負極端子18之方式移動。在圖7(c)的狀 態下，上下電極15、16分別與正極端子17、負極端子18 接觸。下側電極1 6係朝上側按壓方形電池5，方形電池5, ^ 係藉由該按壓而上升。在該狀態下，方形電池5係被充電 ，且充電後上下之電極1 5、1 6，則朝與上述相反的方向移 動，而離開方形電池5。 其次，參照實施例具體說明厚度不同的方形電池5之. 收納。本實施例的電池托盤，係可收納至少從4mm到 • 8mm之範圍的厚度之方形電池5。以下，說明收納4mm、 . 5 m m、6 m m、8 m m之4種厚度的方形電池5之例子。 圖8，係將厚度4mm的方形電池5收納在電池收納部 2內的狀態之俯視圖。圖9 ( a )係圖8的E — E線之剖面 圖，圖9 ( b )係圖8的F - F線之剖面圖。 如圖8的A部所示，方形電池5的其中一方之端部， 係藉由開口 7的水平面1 〇及傾斜面1 2之雙方限制位置。 圖9 ( a)的C部，係顯示將方形電池5的端部以傾斜面 12限制位置之情況。如圖8的B部所示，方形電池5的 -13- 200832787 另一方之端部，係以開口 7的水平面1 1及傾斜面1 3之雙 方限制位置。圖9 ( b )的D部’係顯示將方形電池5的 端部以傾斜面1 3限制位置之情況。 如圖9 ( a ) 、（ b )所示，方形電池5係載置於剖面 V字狀的溝槽3之傾斜面3 a、3 b上。在該狀態下，方形 電池5底部的2條稜線與溝槽3的傾斜面3a、3b線狀接 觸。方形電池5，係藉由載置於溝槽3上，決定了高度方 • 向（箭頭記號b方向）的位置，方形電池5底部係位於距 托盤底面高度hi的位置。 方形電池5，係在載置於溝槽3上的狀態下，保持直 . 立狀態並不穩定。然而，如上所述’方形電池5係位於開 口 7內，方形電池5係藉由傾斜面12限制箭頭記號e方 向的移動，並藉由傾斜面13限制箭頭記號f方向的移動 (參照圖8、9 )。藉此，方形電池5不會倒下，並可保持 直立狀態。 # 圖1 〇，係將厚度5mm的方形電池5a收納在電池收納 、 部2內的狀態之俯視圖。圖ll(a)係圖的G— G線之 剖面圖，圖1 1 ( b )係圖10的Η — Η線之剖面圖。方形電 池5 a與厚度4mm的方形電池5相比，厚度t增大1 mm， 但寬度相同。 如圖1 1 ( a )、（ b )所示，方形電池5a係載置於溝 槽3上，方形電池5a的底面位於距離托盤底面高度h2的 位置。厚度5 m m的方形電池5 a，係比方形電池5其厚度t 增大1 m m。因此，圖11(a) 、（ b )的高度h 2，係比圖 -14- 200832787 9(a) 、（b)的高度hi較高。即，由於溝槽3呈V字狀 ，所以即使是厚度不同的方形電池，亦可改變載置位置的 高度而載置於溝槽3上。 如圖1 0的A部所示，方形電池5的其中一方之端部 ，係藉由開口 7的水平面1 〇及傾斜面1 2之雙方限制位置 。圖11(a)的C部，係顯示將方形電池5的端部以傾斜 面12限制位置之情況。如圖1 〇的B部所示，方形電池5 φ 的另一方之端部，係以開口 7的水平面1 1及傾斜面1 3之 雙方限制位置。圖H ( b )的D部，係顯示將方形電池5 的端部以傾斜面1 3限制位置之情況。 ； 這些狀態，係與使用圖8、9說明的厚度4mm的方形 電池5之情況相同。然而，方形電池5a與方形電池5相 比，由於厚度增加，所以從圖8的位置旋轉移動。對這種 情況，參照圖1 〇、11的各圖具體進行說明。 如圖1 〇所示，方形電池5 a係在一對對角位置上’分 # 別藉由傾斜面1 2、1 3進行位置限制。因此’方形電池5 a . ，其兩端部無法沿著傾斜面1 2、1 3朝箭頭記號d方向旋 轉移動。這是因爲，位於開口 7之對角位置的傾斜面12 與傾斜面1 3之間的距離，係比方形電池5 a的寬度較小之 緣故。 然而，方形電池5a的兩端部之中，與傾斜面12、13 相反的一側並沒有被開口 7限制位置。並且’如上所述’ 方形電池5a係在寬度方向（箭頭記號a方向）上以水平 面1 0和水平面1〗限制位置，但各端部的形狀係爲曲面形 -15- 200832787 狀。因此，可一邊方形電池5 a的兩端部沿著水平面1 0、 11移動，一邊方形電池5a朝箭頭記號c方向旋轉移動。 在這裏，假設以方形電池5a底部的2條稜線與溝槽3 的傾斜面3 a、3 b線狀接觸之狀態被載置。在該狀態下， 若使方形電池5a朝箭頭記號c方向扭轉旋轉，則方形電 池5a底部的2條稜線，係以離開溝槽3的各傾斜面3a、 ^ 3b之方式移動。藉此，從方形電池5a底部的2條稜線與 • 各傾斜面3a、3b線狀接觸的狀態，變爲與各傾斜面3a、 3b以1點、合計2點接觸的狀態。 即，由於方形電池5 a係與方形電池5相比厚度變大 . ，所以無法維持圖8的狀態。然而，如圖1 〇所示，在朝 箭頭記號c方向只旋轉移動角度Θ1，且方形電池5a底部 在溝槽3上的抵接狀態從線接觸變爲點接觸的狀態下，可 保持不會倒下的穩定狀態。角度Θ1，係方形電池的寬度方 向之中心線的旋轉角度。在本實施例中，Θ1爲0.57°。 # 另外，在圖10中，爲了方便圖示，角度Θ1係表示垂 . 直線與方形電池的側面所成的角度。這對於圖1 2的角度 Θ2、Θ3也是相同的。 圖12 ( a)，係將厚度6mm的方形電池5b收納在電 池收納部2內的狀態之俯視圖。圖12(b)，係將厚度 8mm的方形電池5c收納在電池收納部2內的狀態之俯視 圖。如上所述，厚度變大的方形電池5b、5c，則旋轉移動 而收納在收納部2內。角度越大，旋轉角度也越大。方形 電池5b之情況，Θ2爲1.78°。另外，方形電池5c之情況 -16 - 200832787 ，Θ3爲4.4 7 4。。即，根據本實施形態的電池托盤，可收納 厚度不同的多種電池，且所收納的電池之厚度每有所變大 ，收納的電池係能夠以旋轉移動因應厚度的增加量之狀態 ，保持穩定的直立狀態。 以上，說明了本實施形態的電池托盤，係可收納厚度 不同的多種方形電池的情況。如上所述，若收納增加了厚 度的方形電池時，則因應厚度的增加量，方形電池的旋轉 _ 角度也會變大。 然而，上下電極15、16(圖7)抵接的方形電池之中 央部，爲旋轉軸之附近。因而，即使旋轉角度增加，位於 . 中央部的上下電極1 5、1 6與方形電池的各端子的抵接部 之面積，係相同或幾乎沒有改變。因此，即使進行旋轉移 動，也能確保上下電極15、16與方形電池的端子之接觸 面積，在化合工序中可進行可靠的充電。 另外，本實施形態的電池托盤，雖然可收納厚度不同 ® 的方形電池，但是厚度的範圍，係會因上托盤的開口之形 - 狀而受到限制。爲了對應範圍更大的方形電池之厚度，亦 可預先準備開口形狀不同的多種上托盤。如此一來，一面 下托盤共用且一面僅更換上托盤，就可將可收納的方形電 池的厚度之範圍做成較廣的範圍。 並且，同樣地爲了對應廣範圍的方形電池之寬度尺寸 ，藉由使用寬度方向之開口形狀不同的上托盤，可將可收 納的方形電池的寬度之範圍做成較廣之範圍。更且，亦可 將對應厚度、對應寬度的上托盤組合來使用。 -17- 200832787 另外，本實施形態的電池托盤，係以在將厚度4mm 的方形電池收納後時方形電池的旋轉角度爲零之例子進行 了說明，但並不限於此，適當決定即可。 另外，本實施形態的電池托盤，係以在化合工序中使 用的例子進行了說明，但是用途並不限於此。也可以例如 在製造工序間使用於收授電池之際，或作爲電池的保管用 來使用。 φ 另外，本實施形態的電池托盤，係如上所述，即使收 納不同厚度的方形電池，上托盤的開口之形狀亦可保持方 形電池的直立狀態，且在充電時可使電極與方形電池的端 子部接觸。相對於此，在收納時所要求的方形電池之位置 精度寬鬆之情況時，上托盤的開口形狀並不限於本實施形 態的形狀。例如，也可以考慮具備下托盤的V字形之溝槽 形狀，且上托盤的開口之形狀係不做傾斜面而將電池的厚 度方向之尺寸變窄之形狀。即使是這種托盤，也可以收納 # 厚度不同的多種方形電池。 (實施形態2 ) 以下，參照附圖說明實施形態2〜5。以下之說明，係 只對與上述實施形態1不同的部分進行說明。對於其他的 結構，由於與上述實施形態1相同，所以省略重複之說明 〇 圖13，係顯示實施形態2之上下電池托盤中的下托盤 之俯視圖。側面之形狀，係由於與上述實施形態1的圖1 -18- 200832787 (b )相同因此省略。在圖1中，電池收納部2，係相對於 下托盤1的外周之邊傾斜配置。電池收納部2，係在該傾 斜方向上配置成列狀，且各列彼此平行。 相對於此，在圖1 3的結構中，配置成列狀的電池收 納部21的各列彼此平行的這一點係與圖1相同，但各列 係配置成也與下托盤20的外周之邊平行。 圖14，係顯示與圖13的下托盤20對應的上托盤22 Φ 之俯視圖。側面的形狀，係由於與上述實施形態1的圖3 (b )相同因此省略。上托盤22，係除了開口的配置之外 與圖3的上托盤6相同。圖14的開口 23，係配置成在將 -

The method of manufacturing the battery. • [Prior Art] • In the battery manufacturing process, there is a process of processing the battery in a tray. Further, a tray is also used for the collection and storage between manufacturing processes. In the patent documents 1 and 2 (Patent Document 1: JP-A-2000-53 1 82, and JP-A-2002- 3 62 5 66), it is proposed to achieve weight reduction while ensuring A battery tray of the necessary strength. Further, in the step of charging (charging) the battery, in a state in which a plurality of pools are housed in the tray, charging is performed in a state where the electrodes are crimped to the upper and lower terminals of the battery. In this case, it is necessary to ensure reliable charging by ensuring the positional accuracy between the upper and lower ends of the battery and the electrodes. Fig. 20 (a) shows a plan view of an example of a conventional battery tray. This figure shows an example of a tray for a prismatic battery. A plurality of battery storage portions 1 0 1 are provided on the square battery tray 100. Fig. 20 (b) is an enlarged view showing one portion of the battery housing portion 1 〇 1. This figure shows the state after receiving the prismatic battery 102 (hatched portion). Both ends of the battery housing portion 1 〇 1 are narrowed in width, and both end portions of the prismatic battery 1 〇 2 are engaged in this portion. Thereby, the prismatic battery 1 〇 2 200832787 can be stably placed in the battery housing portion 101. Therefore, in the compounding step, the accuracy of the positional relationship between the upper and lower terminals of the prismatic battery 102 and the upper and lower electrodes for charging can be ensured, and charging can be surely completed. [Problem to be Solved by the Invention] However, as described above, the battery tray 100 shown in FIG. 20 has the width of both end portions 103 of the battery housing portion 101 in conformity with the square battery 102. The design of the thickness. Therefore, a dedicated tray must be prepared for each square battery of different thickness. In this case, the mold for forming the tray is also dedicated to each type of tray, which is disadvantageous in terms of cost. Further, in the manufacturing process, it is necessary to change the corresponding tray according to the thickness of the prismatic battery, which is also disadvantageous in terms of production efficiency. Further, in Patent Documents 1 and 2 described above, no particular arrangement has been proposed for a structure in which a plurality of types of batteries can be accommodated. The present invention has been made to solve the above conventional problems, and an object thereof is to provide a battery tray in which a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray. [Means for Solving the Problem] In order to achieve the above object, a battery tray according to the present invention is a battery tray for accommodating a battery, comprising: an opening; and a housing portion provided on a back side of the opening; The inclined portion inside the accommodating portion is spaced apart from the inclined portion, and is widened toward the opening, and the battery can be surrounded by the opening and abutting the inclined portion -6-200832787. In the state, it is accommodated in the storage unit. [Effects of the Invention] According to the present invention, a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray. [Embodiment] [Embodiment of the Invention] The battery tray of the present invention has an inclined portion that widens with respect to the distance between the facing portions as it goes toward the opening. Therefore, even a battery having a different thickness or outer diameter is used. It is also possible to change the height of the placement position and place it on the groove, and to accommodate a plurality of batteries having different thicknesses or outer diameters by one tray. In the battery tray according to the above aspect of the invention, the battery tray is a battery tray for accommodating a cylindrical battery, and the inclined portion is preferably formed to support the bottom of the cylindrical battery at least three points. This structure is suitable for storage of cylindrical batteries with different outer diameters. Further, the inclined portion is a groove including a facing inclined surface, and the interval between the opposing inclined surfaces is preferably widened toward the opening. This structure is suitable for storage of prismatic batteries of different thicknesses. Further, when the state of the battery is observed from the side facing the opening, the opening preferably includes a regulating surface for restricting the movement of the battery in the width direction. According to this configuration, since the movement in the width direction of the battery can be restricted, the battery can be stably accommodated in the width direction. Further, in the case where the state of the battery is observed from the side facing the opening, the opening is preferably a pair of diagonal positions of the battery, and a regulating surface for restricting the rotational movement of the battery is preferable. According to this configuration, even if the thickness of the accommodated battery is increased, a stable upright state can be maintained in a state in which the thickness is increased in accordance with the amount of increase in thickness on the side opposite to the restriction surface that restricts the rotational movement. Further, it is preferable that the restriction surface for restricting the movement in the width direction and the restriction surface for restricting the above-described rotation movement intersect at an obtuse angle. Further, when the battery is erected on the groove, the distance between the inclined surface and the battery is set to be smaller than the distance between the other of the inclined surfaces and the battery. It is ideal to tilt the surface relatively. According to this configuration, it is possible to reduce the sway when storing the prismatic battery having a large thickness, and it is possible to achieve stable storage. Further, it is preferable that the inner circumferential surface of the opening and the inner circumferential surface of the storage portion are on the same plane. According to this configuration, it is easy to form one of the trays. Further, it is preferable that the opening is formed in a plurality of rows of openings, and the respective rows of openings are arranged in parallel with each other. Further, it is preferable that the battery tray has a structure in which a first tray in which the groove is formed and a second tray in which the opening is formed are combined. According to this configuration, the configuration of the mold in the case of the resin-molded tray becomes simple. The above second tray can be replaced with a preferred one. According to this configuration, since the first tray is shared while the second tray is replaced with the tray having the changed opening shape, the thickness of the accommodating battery can be increased to -8 - 200832787. Further, it is preferable that the opening has a tapered surface on a side opposite to the storage portion. According to this configuration, storage of the battery becomes easy. Further, a through hole is formed in the inside of the accommodating portion, and a battery that is accommodated in the accommodating portion by an electrode that passes through the through hole and an electrode on the opening side is preferably used. According to this configuration, the battery tray can be used in the compounding process. Φ Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Specifically, these angles are preferably 100 degrees and an obtuse angle of 150 degrees or less. In the present embodiment, the angle is 120 degrees. • The details will be described later, and the horizontal plane is 1 〇. 1 1 is a restriction surface that restricts the movement of the battery in the width direction (the direction of the arrow mark a), and the inclined surfaces 12 and 13 limit one of the rotational movements of the two directions of the battery (the arrow marks c and d) (arrow) The limit surface of the rotation movement of the mark d direction). When the prismatic battery 5 is housed in the battery housing portion 2, the prismatic battery 5 is inserted into the battery housing portion 2 through the opening 7 from the upper side of the opening 7. In order to facilitate the insertion, a tapered surface 14 is provided on the upper side of the opening 7. As shown in Fig. 4 (a), the prismatic battery 5 is restricted by the horizontal planes 10, 1 1 and the inclined surfaces -11 - 200832787 12, 13 . Therefore, the tapered surface 14 can be attached to each of the four faces. Fig. 5 shows a combination of the upper tray 6 and the lower tray 1. Fig. 5(a) is a plan view, and Fig. 5(b) is a side view.

According to this configuration, it is simple to carry out the resin domain structure. Further, the positioning of the upper and lower trays is performed by fitting the pins to the positioning holes. It is sufficient to integrally form the resin pin and the positioning hole. Next, the compounding process of the battery will be described. Fig. 7 (a) is a plan view showing a state in which the pool 5 is housed in the battery housing portion 2. c) is a cross-sectional view taken along line D-D of Fig. 7(a), Fig. 7 is a state before electric power, and Fig. 7(c) shows a state at the time of charging] > a state in which t is set. As shown in Figure 5 (b), Figure 5 (a) shows the middle part 2. Part of the enlarged map. In Fig. 5 (a (a), in order to accommodate a part of the square 7 at the time of storage, when the bottom surface battery 5 of the battery 5 is formed by the mold of the tray 6 and the lower tray, the positioning pin can be formed. The square battery 5 is opened 7 when the square battery 5 is accommodated as shown in Fig. 7 (a -12-200832787). As shown in Fig. 7(b), the prismatic battery 5 is housed in the accommodating portion 2 in a state of being in contact with the inclined faces 3a and 3b of the groove 3. As shown in Fig. 7 (b), in the compounding process In the upper and lower sides of the prismatic battery 5, the upper electrode 15 and the lower electrode 16 are respectively provided. When charging, the upper electrode 15 is lowered, and moves closer to the positive terminal 17 of the prismatic battery 5. The lower electrode 16 It rises and passes through the through hole 4 to move closer to the negative electrode terminal 18 of the prismatic battery 5. In the state of Fig. 7(c), the upper and lower electrodes 15, 16 are in contact with the positive electrode terminal 17 and the negative electrode terminal 18, respectively. The lower electrode 16 presses the prismatic battery 5 toward the upper side, and the prismatic battery 5, ^ is raised by the pressing. In this state, the square The cell 5 is charged, and after charging, the upper and lower electrodes 15 and 16 move in the opposite direction to the above, and leave the prismatic battery 5. Next, the rectangular battery 5 having different thicknesses will be specifically described with reference to the embodiment. The battery tray of the present embodiment is a prismatic battery 5 which can accommodate a thickness of at least 4 mm to 8 mm. Hereinafter, an example of a rectangular battery 5 having four thicknesses of 4 mm, .5 mm, 6 mm, and 8 mm will be described. Fig. 8 is a plan view showing a state in which a rectangular battery 5 having a thickness of 4 mm is housed in the battery housing portion 2. Fig. 9(a) is a cross-sectional view taken along line E-E of Fig. 8, and Fig. 9(b) is a view of Fig. 8 A cross-sectional view of the line F - F. As shown in part A of Fig. 8, one end portion of the prismatic battery 5 is restricted by both the horizontal plane 1 〇 and the inclined surface 12 of the opening 7. Fig. 9 (a In the C portion, the end portion of the prismatic battery 5 is restricted by the inclined surface 12. As shown in part B of Fig. 8, the other end of the square battery 5-13-200832787 is an opening 7 The horizontal plane 1 1 and the inclined surface 1 3 are both restricted positions. The D part of Fig. 9 (b) shows the square battery The end portion of the fifth portion is restricted by the inclined surface 13 3. As shown in Figs. 9(a) and (b), the prismatic battery 5 is placed on the inclined surface 3a, 3b of the groove 3 having a V-shaped cross section. In this state, the two ridge lines at the bottom of the prismatic battery 5 are in linear contact with the inclined faces 3a, 3b of the groove 3. The prismatic battery 5 is placed on the groove 3 to determine the height direction. At the position of the arrow symbol b direction, the bottom of the prismatic battery 5 is located at a height hi from the bottom surface of the tray. The prismatic battery 5 is kept in a straight state in a state of being placed on the groove 3, and is unstable. However, as described above, the 'square battery 5 is located in the opening 7, and the prismatic battery 5 restricts the movement in the direction of the arrow mark e by the inclined surface 12, and restricts the movement of the arrow mark f direction by the inclined surface 13 (refer to FIG. 9 ). Thereby, the prismatic battery 5 does not fall down and can be kept in an upright state. # Fig. 1 is a plan view showing a state in which a rectangular battery 5a having a thickness of 5 mm is housed in the battery housing portion 2. Fig. 11(a) is a cross-sectional view taken along line G-G of the figure, and Fig. 1 1(b) is a cross-sectional view of the Η-Η line of Fig. 10. The square battery 5 a has a thickness t of 1 mm larger than that of the square battery 5 having a thickness of 4 mm, but the width is the same. As shown in Fig. 1 1 (a) and (b), the prismatic battery 5a is placed on the groove 3, and the bottom surface of the prismatic battery 5a is located at a height h2 from the bottom surface of the tray. The prismatic battery 5 a having a thickness of 5 m is increased by 1 m m than the thickness t of the prismatic battery 5. Therefore, the height h 2 of Figs. 11(a) and (b) is higher than the height hi of Figs. 14-200832787 9(a) and (b). That is, since the groove 3 has a V shape, even a prismatic battery having a different thickness can be placed on the groove 3 by changing the height of the placement position. As shown in part A of Fig. 10, one end portion of the prismatic battery 5 is restricted by both the horizontal plane 1 〇 and the inclined surface 1 2 of the opening 7. The portion C of Fig. 11(a) shows a case where the end portion of the prismatic battery 5 is restricted by the inclined surface 12. As shown in part B of Fig. 1, the other end portion of the prismatic battery 5 φ is restricted by both the horizontal plane 1 1 and the inclined surface 13 of the opening 7. The portion D of Fig. H (b) shows a case where the end portion of the prismatic battery 5 is restricted by the inclined surface 13 . These states are the same as those of the prismatic battery 5 having a thickness of 4 mm as explained with reference to Figs. However, the prismatic battery 5a is rotationally moved from the position of Fig. 8 as compared with the prismatic battery 5 due to the increase in thickness. In this case, the drawings of Figs. 1 and 11 will be specifically described. As shown in FIG. 1A, the prismatic battery 5a is positioned at a pair of diagonal positions by the inclined faces 1 2, 1 3 . Therefore, the square battery 5a., the both end portions thereof cannot be rotated in the direction of the arrow mark d along the inclined faces 1 2, 1 3 . This is because the distance between the inclined surface 12 located at the diagonal position of the opening 7 and the inclined surface 13 is smaller than the width of the prismatic battery 5a. However, among the both end portions of the prismatic battery 5a, the side opposite to the inclined faces 12, 13 is not restricted by the opening 7. Further, the above-mentioned square battery 5a is limited in the width direction (the direction of the arrow mark a) by the horizontal surface 10 and the horizontal plane 1, but the shape of each end portion is a curved shape -15-200832787. Therefore, the prismatic battery 5a can be rotationally moved in the direction of the arrow mark c while the both end portions of the prismatic battery 5a move along the horizontal planes 10 and 11. Here, it is assumed that the two ridge lines at the bottom of the prismatic battery 5a are placed in line contact with the inclined faces 3a, 3b of the groove 3. In this state, when the prismatic battery 5a is twisted and rotated in the direction of the arrow symbol c, the two ridge lines at the bottom of the prismatic battery 5a are moved away from the inclined faces 3a and 3b of the groove 3. As a result, the two ridge lines at the bottom of the prismatic battery 5a are in linear contact with the inclined surfaces 3a and 3b, and the inclined surfaces 3a and 3b are in contact with each other at a point of two points in total. That is, since the prismatic battery 5a is thicker than the prismatic battery 5, the state of Fig. 8 cannot be maintained. However, as shown in FIG. 1A, only the movement angle Θ1 is rotated in the direction of the arrow mark c, and the abutment state of the bottom of the prismatic battery 5a on the groove 3 is changed from the line contact to the point contact, and can be maintained. Falling steady state. The angle Θ1 is the rotation angle of the center line in the width direction of the prismatic battery. In the present embodiment, Θ1 is 0.57°. # Further, in Fig. 10, for convenience of illustration, the angle Θ1 indicates the angle formed by the straight line and the side surface of the prismatic battery. This is the same for the angles Θ2 and Θ3 of Fig. 12. Fig. 12 (a) is a plan view showing a state in which a prismatic battery 5b having a thickness of 6 mm is housed in the battery housing portion 2. Fig. 12 (b) is a plan view showing a state in which the prismatic battery 5c having a thickness of 8 mm is housed in the battery housing portion 2. As described above, the prismatic batteries 5b and 5c having a large thickness are rotatably moved and housed in the accommodating portion 2. The larger the angle, the larger the angle of rotation. In the case of the square battery 5b, Θ2 is 1.78°. In addition, the case of the square battery 5c -16 - 200832787, Θ3 is 4.4 7 4. . In other words, according to the battery tray of the present embodiment, a plurality of types of batteries having different thicknesses can be accommodated, and the thickness of the accommodated battery can be increased, and the stored battery can be stably moved in response to an increase in thickness. Upright state. As described above, the battery tray of the present embodiment has been described as being capable of accommodating a plurality of prismatic batteries having different thicknesses. As described above, when a rectangular battery having an increased thickness is accommodated, the rotation _ angle of the prismatic battery is also increased in response to the increase in thickness. However, the central portion of the prismatic battery in which the upper and lower electrodes 15, 16 (Fig. 7) abuts is in the vicinity of the rotating shaft. Therefore, even if the rotation angle is increased, the areas of the abutting portions of the upper and lower electrodes 15 and 16 located at the center portion and the terminals of the prismatic battery are the same or hardly changed. Therefore, even if the rotational movement is performed, the contact area between the upper and lower electrodes 15 and 16 and the terminals of the prismatic battery can be ensured, and reliable charging can be performed in the compounding step. Further, in the battery tray of the present embodiment, a prismatic battery having a different thickness can be accommodated, but the range of the thickness is limited by the shape of the opening of the upper tray. In order to correspond to the thickness of a square battery having a larger range, a plurality of upper trays having different opening shapes may be prepared in advance. In this way, the thickness of the storable prismatic battery can be made into a wide range even if the lower tray is shared and only the upper tray is replaced. Further, in the same manner, in order to correspond to the width dimension of a wide range of prismatic batteries, by using the upper tray having different opening shapes in the width direction, the range of the width of the receivable rectangular battery can be made into a wide range. Furthermore, it is also possible to use an upper tray of a corresponding thickness and a corresponding width. -17-200832787 The battery tray of the present embodiment has been described as an example in which the rotation angle of the prismatic battery is zero when the rectangular battery having a thickness of 4 mm is accommodated. However, the present invention is not limited thereto and may be appropriately determined. Further, the battery tray of the present embodiment has been described as an example used in the compounding step, but the application is not limited thereto. For example, it may be used for the purpose of storing a battery during the manufacturing process or for storage of a battery. φ Further, in the battery tray of the present embodiment, as described above, even if a rectangular battery having a different thickness is accommodated, the shape of the opening of the upper tray can maintain the upright state of the prismatic battery, and the terminal of the electrode and the prismatic battery can be charged during charging. Contact. On the other hand, when the position of the prismatic battery required for storage is loose, the shape of the opening of the upper tray is not limited to the shape of the present embodiment. For example, it is also conceivable to have a V-shaped groove shape of the lower tray, and the shape of the opening of the upper tray is a shape that narrows the thickness direction of the battery without making an inclined surface. Even with this type of tray, you can store a variety of square batteries with different thicknesses. (Embodiment 2) Hereinafter, Embodiments 2 to 5 will be described with reference to the drawings. In the following description, only portions different from the above-described first embodiment will be described. The other configurations are the same as those of the above-described first embodiment, and therefore the overlapping description will be omitted. Fig. 13 is a plan view showing the lower tray in the lower battery tray in the second embodiment. The shape of the side surface is the same as that of Fig. 1 -18 to 200832787 (b) of the above-described first embodiment, and therefore will be omitted. In Fig. 1, the battery housing portion 2 is disposed obliquely with respect to the outer circumference of the lower tray 1. The battery housing portions 2 are arranged in a row in the oblique direction, and the columns are parallel to each other. On the other hand, in the configuration of FIG. 13 , the rows of the battery storage portions 21 arranged in a line are parallel to each other as in FIG. 1 , but the rows are arranged also on the outer circumference of the lower tray 20 . parallel. Fig. 14 is a plan view showing the upper tray 22 Φ corresponding to the lower tray 20 of Fig. 13. Since the shape of the side surface is the same as that of Fig. 3 (b) of the above-described first embodiment, it is omitted. The upper tray 22 is the same as the upper tray 6 of Fig. 3 except for the arrangement of the openings. The opening 23 of Fig. 14 is arranged to correspond to the battery housing portion 21 when the upper tray 22 is placed on the lower tray 20 of Fig. 13 . That is, each row of the openings 7 is arranged to be parallel to the side of the outer circumference of the upper tray 22. In the present embodiment, the number of batteries per unit area is smaller than that of the tray of the first embodiment, but the arrangement of the battery housing portion 21 and the opening 2 3 # is simplified. Therefore, there is a case where the device for setting the tray and the device for accessing the tray to the battery and the battery are easily installed. (Embodiment 3) The trays of the first and second embodiments are separated into an upper tray and a lower tray. However, in the tray of the third embodiment, the upper and lower trays are integrally formed. Fig. 15 (a) shows a plan view of the portion of the opening 24, Fig. 15 (b) is a sectional view of the I-I line of Fig. 15 (a), and Fig. 15 (c) is a J of Fig. 15 (a) A cross-sectional view of the J line. -19 - 200832787 When the upper and lower trays are integrally formed as shown in Fig. 6(b), it is difficult to pull out the mold in the accommodating portion 2 from the accommodating portion 2. In the cross-sectional view of Fig. 15 (b), the inner circumferential surface of the opening 24 and the inner circumferential surface of the accommodating portion 25 are on the same plane. Similarly, in the cross-sectional view of Fig. 15 (c), the inner circumferential surface of the opening 24 and the inner circumferential surface of the accommodating portion 25 are on the same plane. In this configuration, it is easy to pull out the mold from the accommodating portion 25, and it is possible to easily form a tray in which the upper and lower trays are integrated. # This embodiment is easy to form and is very effective in limiting the width of the battery to be stored. (Embodiment 4) Fig. 16 is a cross-sectional view showing a tray of a fourth embodiment. This figure is equivalent to Fig. 9 (a) of the E-E line sectional view of Fig. 8. Hereinafter, description will be made in comparison with the embodiment 1. The prismatic battery 5 of Fig. 16 is the same as the prismatic battery 5 of Fig. 9(a). The two ridge lines at the bottom of the prismatic battery 5 are in line contact with the inclined faces 2 6 a, 2 6 b of the groove 26 ® , and the prismatic battery 5 is placed at a position hl from the bottom surface of the tray. This placed state is the same as that of the prismatic battery 5 of Fig. 9(a) of the embodiment j. The structure of Fig. 16 is different from the configuration of Fig. 9(a) in that the inclination angles of the inclined faces 26a and 26b are different. In Fig. 16, the inclined faces 26a, 26b are disposed such that the distance between the inclined face 26b and the battery 5 is greater than the distance between the inclined face 2 and the battery 5 when the battery 5 is erected on the groove 26. small. The 5a phase prismatic battery 5a is the same battery as the prismatic battery -20-200832787 shown in Fig. 1 1 (a). The prismatic battery 5a of Fig. 16 is placed at a position h2 from the bottom surface of the tray, similarly to Fig. U(a). As described above, when the prismatic battery 5a is placed, the prismatic battery 5a is located at a position where the prismatic battery 5 is placed and rotated in the direction of the arrow symbol c in Fig. 1A. At this time, as shown in Fig. 11 (a), a gap is formed between the ridge line at the bottom of the prismatic battery 5a and the inclined surface 3b. On the other hand, in Fig. 16, a gap is formed between the ridge line at the bottom of φ of the prismatic battery 5a and the inclined surface 26b, but the size thereof is smaller than the gap of Fig. 1 1 (a). Further, in Fig. 16, the prismatic battery 5b is the same battery as the prismatic battery 5b shown in Fig. 12 (a). Square battery _ 5b, the position is placed at a height h3 from the bottom of the tray. Thereby, the gap between the ridge line of the prismatic battery 5b and the inclined surface 26b becomes larger than when the square battery 5a is placed. However, the gap is smaller than the gap in the case where the prismatic battery 5b is placed in the structure of Fig. 11 (a). As described above, according to the configuration of Fig. 16, in the case of placing a square battery having a large thickness, the gap between the ridge line and the inclined surface 26b of the prismatic battery can be made smaller than that of the structure of Fig. This is because, as described above, the inclined faces 26a, 26b are disposed such that the distance between the inclined faces 26b and the battery 5 is smaller than the distance between the inclined faces 26a and the battery 5. In other words, according to the present embodiment, even if the thickness of the rectangular battery to be housed is increased, the increase in the gap between the ridge line at the bottom of the prismatic battery and the inclined surface can be suppressed. As a result, it is possible to reduce the sway when storing a rectangular battery having a large thickness, and it is possible to achieve stable storage. Further, the above description has been made by taking an example corresponding to the cross section of the E-E line of Fig. 8 and the cross section of the G-G line of Fig. 10 to Fig. 10, but for the F of Fig. 8 The cross section of the F line and the section corresponding to the Η11 line of Fig. 10 are also the same. However, in this case, the inclined surface contacted by the bottom of the prismatic battery 5b is as shown in Fig. 9 (b) and Fig. 11 (b), and the opposite side is shown, so that the inclined surface 2 6 a shown in Fig. 16. The setting of the tilt angle of 2 6 b is also reversed. (Embodiment 5) Fig. 17 is a plan view showing a lower tray in the upper and lower battery trays of the fifth embodiment. The shape of the side surface is the same as that of Fig. 1 (b) of the above-described first embodiment, and therefore will be omitted. Fig. 18 is a plan view showing the upper tray 32 corresponding to the lower tray 30 of Fig. 17. The shape of the side surface is the same as that of Fig. 3 (b) of the above-described first embodiment, and therefore will not be described. In the example of Figs. 1, 7 and 18, the inclined portion inside the accommodating portion 31 of the lower tray 30 is formed into a conical surface, and the opening 3 3 of the upper tray 3 2 is rounded, so that it can be housed outside. Cylindrical # batteries with different diameters. Since the mounting portion is a conical surface, in the present embodiment, a cylindrical battery having a different outer diameter can be accommodated. This will be specifically described with reference to Fig. 19. Fig. 19 is a cross-sectional view showing a state in which the lower tray 30 of Fig. 17 and the upper tray 32 of Fig. 18 are combined. An inclined portion 34 is formed inside the accommodating portion 31. In the example of Fig. 19, the inclined portion 34 is a conical surface. The entire circumference of the bottom of the accommodated cylindrical battery 35a is in contact with the inclined portion 34. The cylindrical battery 35b is a battery having a larger outer diameter than the cylindrical battery 35a. When the cylindrical battery 35b is housed, the position of the bottom portion becomes higher than that of the storage period of the cylindrical battery 35&-22-200832787, but the entire circumference of the bottom portion does not change with the inclined portion 34, and the cylindrical battery 35a can be stored in the same way. For a cylindrical battery that can be accommodated, for example, a battery of at least No. 1 (diameter: 34.2 mm) to No. 4 (diameter: 1 〇·5πιπ1) can be considered. In Figs. 17 to 19, an example in which the inclined portion is formed into a conical surface has been described, but the invention is not limited thereto. That is, the inclined portion 34 may be a shape that can be widened toward the opening 33 and can support the bottom of the battery by at least three points, for example, a pyramidal surface. Further, the inclined portion 34 is not limited to a planar shape, and for example, three or more ribs may be inclined. Similarly, the opening 33 of the upper tray 32 is not limited to a circular shape, and may be a polygonal shape such as a triangle or more. Further, in the present embodiment, the upper and lower trays can be integrally formed by forming the inner peripheral surface of the opening 33 and the inner peripheral surface of the accommodating portion 31 on the same plane, which is the same as in the third embodiment. [Industrial Applicability] As described above, according to the present invention, since a plurality of batteries having different thicknesses or outer diameters can be accommodated by one tray, the battery tray of the present invention can be used, for example, during charging in a compounding step. The trays are used to store trays during the manufacturing process or to store trays for batteries.
