Description

本発明は、電池容器に電解液を注液する電解液注液装置に関し、特に大容量の電池容器に精度の高い注液を短時間で行うことができるものに関する。   The present invention relates to an electrolyte solution injection device that injects an electrolyte solution into a battery container, and more particularly to an apparatus that can perform high-precision liquid injection into a large-capacity battery container in a short time.

従来技術は、電池容器内を減圧引きし、その後、定量吐出ポンプにて１回で注液するものが一般的である（例えば特許文献１参照）。

上述した電解液注液方法であると次のような問題があった。すなわち、定量吐出ポンプの吐出精度は、ポンプの吐出量に対する割合で決まる。このため、吐出量が多いポンプであればあるほど精度が悪くなることになる。このため、大きな容積の電池容器に大量の電解液を注入する場合、ばらつきも多くなり、精度よく注液することができない。また、注液プロセスは含浸させながら進行していく、１回の注液では含浸が完了して最終的に全量の注液が完了するまでには多くの時間がかかり、効率が非常に悪い。   The electrolyte solution injection method described above has the following problems. That is, the discharge accuracy of the metering pump is determined by the ratio to the pump discharge amount. For this reason, the more the pump is discharged, the worse the accuracy. For this reason, when a large amount of electrolyte is injected into a battery container having a large volume, the variation increases, and the liquid cannot be accurately injected. In addition, the liquid injection process proceeds while impregnating, and it takes a long time until the impregnation is completed and finally the total amount of liquid injection is completed in one injection, and the efficiency is very poor.

The amount of liquid to be injected into the battery container W is the first liquid injection amount Q1. Further, the battery container W is held by a holder H in order to prevent the container from expanding during decompression or liquid injection. Furthermore, as shown in FIG. 3, eight battery containers W are accommodated in the carrier C.

このように構成された電解液注液装置１０では、次のようにして電解液の注液を行う。なお、便宜上１つの電池容器Ｗについて説明するが、他の電池容器Ｗについても同様に注液が行われる。   In the electrolytic solution injection device 10 configured as described above, the electrolytic solution is injected as follows. In addition, although one battery container W is demonstrated for convenience, liquid injection is performed similarly about the other battery container W.

最初に、デパレタイザ２０によりパレットから電池容器Ｗが取り出され、空のキャリアＣに移載される。そして、キャリアＣは搬送コンベア１１により前秤量部３０へ搬送される。前秤量部３０では、電池容器Ｗの重量が計測される。計測値Ｍ１は制御部１００に送られる。そして、キャリアＣは搬送コンベア１１により第１注液部４０へ搬送される。   First, the battery container W is taken out of the pallet by the depalletizer 20 and transferred to the empty carrier C. Then, the carrier C is transported to the pre-weighing unit 30 by the transport conveyor 11. In the pre-weighing unit 30, the weight of the battery container W is measured. The measurement value M1 is sent to the control unit 100. Then, the carrier C is transported to the first liquid injection unit 40 by the transport conveyor 11.

第１注液部４０では、シャッタ開閉シリンダ４８が作動し、シャッタ部４７が閉じられ、減圧チャンバ４１が気密室となる。減圧ポンプ（不図示）により減圧チャンバ４１内が電解液の飽和蒸気圧よりわずかに高い気圧まで減圧される。そして、リフタシリンダ４６が作動し、電池容器Ｗの注液口Ｗａにノズル４２が挿入されるまでキャリアＣを上昇させる。なお、注液前の電解液は電解液脱泡槽４５で脱泡された後、大容量ポンプ４４内に所定の注液量ＱＸが吸入されて待機状態となっている。なお、注液量ＱＸは第１の注液量Ｑ１の８０％に設定されている。   In the first liquid injection part 40, the shutter opening / closing cylinder 48 is operated, the shutter part 47 is closed, and the decompression chamber 41 becomes an airtight chamber. The inside of the decompression chamber 41 is decompressed to a pressure slightly higher than the saturated vapor pressure of the electrolyte by a decompression pump (not shown). Then, the lifter cylinder 46 is operated to raise the carrier C until the nozzle 42 is inserted into the liquid injection port Wa of the battery container W. The electrolyte before injection is defoamed in the electrolyte deaeration tank 45, and then a predetermined injection amount QX is sucked into the large-capacity pump 44 and is in a standby state. The injection amount QX is set to 80% of the first injection amount Q1.

次に、注液バルブ４３を開け、大容量ポンプ４４から電解液を押し出す。注液量ＱＸの電解液が電池容器Ｗ内に高速で注液され、電池容器Ｗ内の電極に電解液が含浸してゆく。   Next, the liquid injection valve 43 is opened and the electrolytic solution is pushed out from the large capacity pump 44. The electrolyte solution of the injection amount QX is injected into the battery container W at high speed, and the electrode in the battery container W is impregnated with the electrolyte solution.

そして、リフタシリンダ４６を作動し、電池容器Ｗを下げ、減圧チャンバ４１内を大気圧に戻す。次に、シャッタ開閉シリンダ４８が作動し、シャッタ部４７が開かれ、キャリアＣを取り出す。キャリアＣは搬送コンベア１１により中間秤量部５０へ搬送される。   Then, the lifter cylinder 46 is operated, the battery container W is lowered, and the inside of the decompression chamber 41 is returned to the atmospheric pressure. Next, the shutter opening / closing cylinder 48 is operated, the shutter portion 47 is opened, and the carrier C is taken out. The carrier C is transported to the intermediate weighing unit 50 by the transport conveyor 11.

なお、第１注液部４０では、減圧チャンバ４１内への移載、減圧引き、注液、含浸、大気圧戻しなどのプロセスがあるため、４台の第１注液部４０において同様の作業が並行して行われている。   In the first liquid injection unit 40, there are processes such as transfer into the vacuum chamber 41, vacuum pulling, liquid injection, impregnation, and return to atmospheric pressure. Therefore, the same operations are performed in the four first liquid injection units 40. Are done in parallel.

中間秤量部５０では電池容器Ｗの重量を計測し、その計測値Ｍ２が制御部１００に送られる。制御部１００では、計測値Ｍ１と計測値Ｍ２との差に基づいて、実際に注液された第２の注液量Ｑ２を算出する。そして、第１の注液量Ｑ１までの残量、すなわち第３の注液量Ｑ３を算出する。なお、第３の注液量Ｑ３は第１の注液量Ｑ１の２０％程度となる。第３の注液量Ｑ３は第２の注液部６０に送られる。   The intermediate weighing unit 50 measures the weight of the battery container W, and the measured value M2 is sent to the control unit 100. The control unit 100 calculates a second liquid injection amount Q2 actually injected based on the difference between the measurement value M1 and the measurement value M2. Then, the remaining amount up to the first liquid injection amount Q1, that is, the third liquid injection amount Q3 is calculated. The third injection amount Q3 is about 20% of the first injection amount Q1. The third liquid injection amount Q3 is sent to the second liquid injection unit 60.

第２の注液部６０では、精密ポンプ６１により第３の注液量Ｑ３の電解液が吸入される。電池容器Ｗの注液口Ｗａにノズルが挿入され、精密ポンプ６１により第３の注液量Ｑ３の電解液が注液される。なお、この注液は大気圧下で行う。第３の注液量Ｑ３の注液が終了後、キャリアＣは搬送コンベア１１により最終秤量部７０へ搬送される。   In the second liquid injection unit 60, the precision pump 61 sucks the third liquid injection amount Q3 of the electrolytic solution. A nozzle is inserted into the liquid injection port Wa of the battery container W, and the electrolytic solution of the third liquid injection amount Q3 is injected by the precision pump 61. In addition, this injection is performed under atmospheric pressure. After the liquid injection of the third liquid injection amount Q3 is completed, the carrier C is transported to the final weighing unit 70 by the transport conveyor 11.

最終秤量部７０で電池容器Ｗの重量を計測し、その計測値Ｍ３は制御部１００に送られる。キャリアＣは搬送コンベア１１により不良払出し部８０へ搬送される。   The final weighing unit 70 measures the weight of the battery container W, and the measured value M3 is sent to the control unit 100. The carrier C is transported to the defective payout unit 80 by the transport conveyor 11.

制御部１００では、計測値Ｍ３に基づいて最終的な注液量を算出し、上述した第１の注液量Ｑ１との差分を求める。この差分が許容範囲内であれば良品、許容範囲外であれば不良品と判断され、この情報は不良払出し部８０に送られる。   In the control unit 100, a final liquid injection amount is calculated based on the measured value M3, and a difference from the above-described first liquid injection amount Q1 is obtained. If this difference is within the allowable range, it is determined as a non-defective product, and if it is outside the allowable range, it is determined as a defective product, and this information is sent to the defective payout unit 80.

不良払出し部８０では、不良品と判断された電池容器Ｗは不良品パレット（不図示）に移載される。良品と判断された電池容器ＷはキャリアＣに載せられたまま、パレタイザ９０に搬送される。パレタイザ９０では、キャリアＣから電池容器Ｗが取り出され、パレットに移載される。空のキャリアＣはリターンコンベア１２により、デパレタイザ２０に搬送される。   In the defective delivery unit 80, the battery container W determined to be defective is transferred to a defective product pallet (not shown). The battery container W determined to be non-defective is conveyed to the palletizer 90 while being placed on the carrier C. In the palletizer 90, the battery container W is taken out from the carrier C and transferred to the pallet. The empty carrier C is conveyed to the depalletizer 20 by the return conveyor 12.

上述したように本実施の形態に係る電解液注液装置１０によれば、大容量ポンプ４４で高速に注液した後、重量を計測し、その重量に基づいて不足分の電解液を高精度の精密ポンプ６１で注液するようにしている。すなわち、１回目の注液における大容量ポンプ４４での誤差分を測定して、２回目の精密ポンプ６１でその誤差分をフィードバックして高精度注液することになる。このため、大容積の電池容器Ｗに対して電解液を注入する場合であっても、精度良く、かつ、効率的に注液することが可能となる。   As described above, according to the electrolyte solution injection device 10 according to the present embodiment, after the liquid is injected at high speed with the large-capacity pump 44, the weight is measured, and the insufficient amount of the electrolyte is accurately measured based on the weight. The precision pump 61 is used for liquid injection. That is, the error in the large-capacity pump 44 in the first injection is measured, and the error is fed back in the second precision pump 61 to perform high-precision injection. For this reason, even if it is a case where electrolyte solution is inject | poured with respect to the large volume battery container W, it becomes possible to inject with sufficient precision and efficiently.

なお、計測値Ｍ１〜Ｍ３に基づいて、大容量ポンプ４４による注液量を最適化するようにしてもよい。また、電解液を２回に分割して注液したが、３回以上に分割して注液してもよい。   Note that the amount of liquid injected by the large-capacity pump 44 may be optimized based on the measured values M1 to M3. Moreover, although electrolyte solution was divided | segmented into 2 times and injected, you may divide | segment and inject into 3 or more times.

なお、本発明は上記実施形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上記実施形態に開示されている複数の構成要素の適宜な組み合わせにより、種々の発明を形成できる。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。さらに、異なる実施形態にわたる構成要素を適宜組み合わせてもよい。   Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

本発明によれば、大容積の電池容器に対して電解液を注入する場合であっても、注液量が多くても精度良く、かつ、効率的に注液することが可能な電解液注液装置が得られる。   According to the present invention, even when the electrolytic solution is injected into a large-capacity battery container, the electrolytic solution can be injected accurately and efficiently even if the amount of the injected solution is large. A liquid device is obtained.
