Abstract
Description
本発明は捲回装置に関する。詳しくはコンデンサーや一次、二次電池等の製造の際に使用する捲回装置に関する。 The present invention relates to a winding device. More specifically, the present invention relates to a winding device used in the manufacture of capacitors, primary and secondary batteries.
例えば、リチウム電池等の一次、二次電池素子(以下単に電池素子と称す)は、金属集電体に一定の間隔で正極活物質が設けられた塗布部を有する正極集電体と、金属集電体に一定の間隔で負極活物質が設けられた塗布部を有する負極集電体とを備え、この正、負極集電体(電池素子材料)とがセパレーター等絶縁体を介して捲回されたものを電池素子とし、ケース内に収容して構成されている。 For example, a primary and secondary battery element (hereinafter simply referred to as a battery element) such as a lithium battery includes a positive electrode current collector having a coating portion in which a positive electrode active material is provided at a predetermined interval on a metal current collector, and a metal current collector. And a negative electrode current collector having a coating portion in which a negative electrode active material is provided at regular intervals, and the positive and negative electrode current collectors (battery element materials) are wound through an insulator such as a separator. The battery element is used as a battery element and accommodated in a case.
このような構成の電池素子を得る捲回装置では、それぞれロール状に巻き上げられた正・負極電池素子材料(原反)及びセパレーター等絶縁体を捲回部まで間欠的かつ断続的に送り出し、捲回部巻芯によって捲回し、正・負極電池素子材料及びセパレーター等絶縁体を所定の長さに切断して電池素子としている。この正・負極電池素子材料の原反部より捲回する過程で、端子となるタブを溶接し電池素子を捲回することになる。 In the winding device for obtaining the battery element having such a configuration, the positive and negative battery element materials (raw material) and separators, such as separators, wound up in a roll shape are intermittently and intermittently sent to the winding part, The battery element is wound by a winding core to cut the positive / negative battery element material and the insulator such as a separator into a predetermined length. In the process of winding from the original fabric portion of the positive / negative battery element material, the tab serving as the terminal is welded to wind the battery element.
今日、正・負極電池素子材料及びセパレーター等の絶縁体の厚みが薄くなり、端子となるタブの切断で生じたカットバリが、材料を傷つけ、電池素子の品質の向上に妨げとなってきた。 Today, the thickness of insulators such as positive and negative electrode battery element materials and separators has been reduced, and cut burrs generated by cutting tabs serving as terminals have damaged the materials and hindered the improvement of battery element quality.
上述したタブを所定の長さに切断後、切断部を処理することなく正・負極電池素子材料に溶接しただけでは、切断で生じたタブのカットバリが、正・負極電池素子材料及びセパレーター等の絶縁体を傷つけ、電池の品質向上が図れない。 After cutting the above-described tab into a predetermined length and then welding it to the positive / negative electrode battery element material without processing the cut portion, the tab burr generated by cutting may be caused by the positive / negative electrode battery element material, separator, etc. The insulator is damaged and the quality of the battery cannot be improved.
本発明はこれらの問題を解決するものであり、正・負極電池素子材料に入る切断面を潰した後、タブを溶解し、捲回することで正・負極電池素子材料及びセパレーター等の絶縁体を傷つけることなく、巻き上げることが可能となり、電池の品質向上を図ることが可能となる。 The present invention solves these problems, and after crushing the cut surface entering the positive / negative electrode battery element material, the tab is dissolved and wound to wind the insulator such as the positive / negative electrode battery element material and the separator. The battery can be wound up without damaging the battery, and the quality of the battery can be improved.
前記の課題を解決する為に、本発明では、端子となるタブを切断した後、カットで生じたバリを、切断に使用したカッターのタブの進行方向と逆面に取り付けた金属土台に一度移動させ、切断で使用するカッターと同動作で、金属土台でタブをプレスしカットバリを潰すこととする。 In order to solve the above-mentioned problem, in the present invention, after cutting the tab to be the terminal, the burr generated by the cutting is once moved to the metal base attached to the opposite side of the traveling direction of the tab of the cutter used for cutting. In the same operation as the cutter used for cutting, the tab is pressed with a metal base to crush the cut burr.
この機構構成によって、正・負極電池素子材料及びセパレーター等の絶縁を傷つけることなく、二次電池素子の品質を高精度で均質に捲き上げることができる。さらに、カットバリを潰すプレス台をカッターの裏側に取り付け、省スペース、少動作でカットバリを潰すことで、工程の短縮、生産原価の低減を図り、高品質の電池素子を巻き取ることが可能となる。 With this mechanism configuration, the quality of the secondary battery element can be uniformly and accurately raised without damaging the insulation of the positive and negative battery element materials and the separator. Furthermore, by attaching a press stand to crush the cut burr on the back side of the cutter, crushing the cut burr with less space and little operation, it is possible to shorten the process and reduce production costs, and to wind up high-quality battery elements. .
本発明は以上説明した通りであり、タブを切断する工程で生じるカットバリを潰し、正・負極電池素子材料及びセパレーター等の絶縁体を傷つけることなく、巻き上げることが可能となり、尚且つ、省スペース、少動作で工程の短縮、生産原価の低減を図り、電池の品質向上を可能となる。The present invention is as described above, crushing the cut burr generated in the step of cutting the tab, it is possible to wind up without damaging the positive and negative battery element material and the insulator such as the separator, and space-saving, With fewer operations, the process can be shortened, the production cost can be reduced, and the quality of the battery can be improved.
本発明の実施の形態を図面により具体的に説明する。図1に示すように、タブを切断するにあたり、上刃1a、下刃1b、プレス台1cの構成になっており、上刃1aが下に稼動することで、挿入したタブ1dを切断し、上刃1aは元の位置に戻ることになる。Embodiments of the present invention will be specifically described with reference to the drawings. As shown in FIG. 1, when cutting the tab, the
次に切断したタブ1dの切断面1eをプレス台1cに移動させ、再び上刃1aの下に稼動する動作により、切断面のタブカットバリを潰し、上刃1aが元の位置に戻る。その後、タブを正・負極電池素子材料1fにタブを移動させ、溶接する動作を繰り返す。 Next, the
図2において、タブ2dを上刃2a、下刃2bの位置に挿入し、上刃2aが下に移動することで上刃2aと下刃2bが交わりタブ2dを切断する。その後上2aが上に移動することで切断の動作は完了する。
次に、切断で生じたカットバリの動作を示す。
切断したタブ2gは、カット面をプレス台2cに移動し、プレス台2cが下に移動することで、切断で生じたカットバリを潰す。その後プレス台は元の位置に戻り、タブのカットバリ潰しの動作は完了する。In FIG. 2, the
Next, the operation of the cut burr generated by cutting will be described.
The cut tab 2g moves the cut surface to the press table 2c, and the press table 2c moves downward to crush the cut burr generated by the cutting. Thereafter, the press table returns to the original position, and the operation of tab burr crushing is completed.
