Description
本發明係為一種鉛酸電池的封裝方法及構造,技術內容是在注酸蓋板上設置金屬端子座,並改變密封極柱孔與焊接接電端子的步驟順序,避免接電端子在注酸、充電的過程中受到酸液污染、腐蝕。 The invention relates to a packaging method and a structure of a lead-acid battery, the technical content is that a metal terminal block is arranged on the acid-injecting cover plate, and the sequence of steps of sealing the pole hole and the soldering electrical terminal is changed, thereby avoiding the acid-contacting terminal being acid-injected In the process of charging, it is contaminated and corroded by acid.
如第一、二圖所示,傳統鉛酸電池包含一容置有電池極群100的電池槽200、以及一封閉於電池槽200上方的注酸蓋板300,其中該電池極群100具有上凸而能夠導接到外部的正、負極柱101,該注酸蓋板300預設有複數注酸孔301以及二分別位於正、負極柱101上方的凹槽302,每一凹槽302內分別設有一供正、負極柱101嵌合的極柱孔303。 As shown in the first and second figures, the conventional lead-acid battery includes a battery well 200 accommodating the battery pole group 100, and an acid-injecting cover 300 closed above the battery tank 200, wherein the battery pole group 100 has The positive and negative electrode columns 101 are convexly connected to the outside, and the acid-injecting cover plate 300 is pre-positioned with a plurality of acid injection holes 301 and two grooves 302 respectively located above the positive and negative electrode columns 101, and each groove 302 is respectively A pole hole 303 is provided for the positive and negative electrode posts 101 to be fitted.
傳統鉛酸電池的封裝方法大致包括: The packaging method of the traditional lead-acid battery generally includes:
(a)將注酸蓋板300封閉於電池槽200上方,使該正、負極柱101分別穿出二極柱孔303,並且在正、負極柱101外圍分別設置一止漏O環304以封閉極柱孔303後,將注酸蓋板300與電池槽200上方周圍熱熔接或利用樹脂接著密封。 (a) The acid-injecting cover plate 300 is closed above the battery cell 200, so that the positive and negative electrode columns 101 respectively pass through the two-pole column hole 303, and a leak-stop O-ring 304 is respectively disposed on the periphery of the positive and negative electrode columns 101 to be closed. After the pole hole 303, the acid-injecting cover 300 is thermally welded to the upper periphery of the battery tank 200 or sealed with a resin.
(b)將正、負極柱101頂端分別與一接電端子102的底端焊接固定後,使二接電端子102與正、負極柱101電性連接。 (b) After the top ends of the positive and negative electrodes 101 are respectively soldered to the bottom end of one of the electrical terminals 102, the two electrical terminals 102 are electrically connected to the positive and negative electrodes 101.
(c)分別對二凹槽302灌膠填充環氧樹脂(Epoxy)形成一封裝體305,該封裝體305遮蓋包覆止漏O環304、正、負極柱101以及接電端子102的底端,同時密封極柱孔303。 (c) forming a package 305 by filling the epoxy resin (Epoxy) into the two recesses 302, the package 305 covering the bottom of the covered leak-proof O-ring 304, the positive and negative columns 101, and the electrical terminal 102. At the same time, the pole hole 303 is sealed.
(d)由注酸蓋板300之複數注酸孔301中注入酸液至電池槽200內後,以密封蓋封閉複數注酸孔301。 (d) After the acid solution is injected into the battery well 200 from the plurality of acid injection holes 301 of the acid injection cap 300, the plurality of acid injection holes 301 are closed by a sealing cap.
(e)將二接電端子102分別電性連接於外部電源,使外部電源通過二接電端子102以及正、負極柱101對電池極群100進行充電。 (e) The two power terminals 102 are electrically connected to the external power source, and the external power source charges the battery pole group 100 through the two power terminals 102 and the positive and negative poles 101.
(f)清潔在注酸、充電過程中溢出於注酸蓋板300與電池槽200外部的酸液,並且清理接電端子102完成封裝,最後在注酸蓋板300設置一上蓋306遮蔽注酸孔301,即成為鉛酸電池的成品。 (f) cleaning the acid solution overflowing the acid-injecting cover 300 and the outside of the battery tank 200 during the acid injection and charging process, and cleaning the electrical terminal 102 to complete the packaging, and finally providing an upper cover 306 to shield the acid injection in the acid-injecting cover 300 The hole 301 is a finished product of a lead-acid battery.
上述封裝方法沿用已久,但長期存在有諸多問題,其一是上述傳統鉛酸電池的製造步驟是先將接電端子102固定在注酸蓋板300後,再實施注酸、充電等電池化成(活化)步驟,此過程中,酸液無可避免地會與電池極群100產生強烈的化學反應,如果沒有使用溢流瓶承接酸液的話,會讓酸液泡沫或酸霧由複數注酸孔301溢出到注酸蓋板300外部;而即使裝設了溢流瓶承接溢出的酸液,也因為承接酸液過程中容易有殘餘酸液由溢流瓶滴落,造成酸液污染、腐蝕接電端子102的情形,不但影響接電端子102外觀的完整性以及導電性,還會因此使整個鉛酸電池被認定為不良品予以報廢。 The above packaging method has been used for a long time, but there are many problems for a long time. One is that the conventional lead-acid battery is manufactured by first fixing the electrical terminal 102 to the acid-injecting cover 300, and then performing battery formation such as acid injection and charging. (activation) step, in which the acid will inevitably generate a strong chemical reaction with the battery pole group 100. If the overflow bottle is not used to accept the acid solution, the acid foam or acid mist will be acidified by a plurality of acids. The hole 301 overflows to the outside of the acid-injecting cover plate 300; and even if the overflow bottle is installed to receive the overflowed acid solution, it is easy to have residual acid liquid dripping from the overflow bottle during the process of accepting the acid solution, causing acid contamination and corrosion. In the case of the electrical terminal 102, not only the integrity and conductivity of the electrical terminal 102 are affected, but also the entire lead-acid battery is rejected as a defective product.
其二是環氧樹脂雖然與金屬有良好的結合強度,但注酸蓋板300的材質通常為ABS或PP等塑膠材質,而環氧樹脂與塑膠材質的結合強度較差,使得封裝體305與注酸蓋板300之間的結合強度可能無法承受化學反應壓力,不但在製程中容易導致酸液從極柱孔303、封裝體305與凹槽302之間溢出而污染、腐蝕接電端子102,長期使用下電池槽200內的酸液也容易由該位置滲出,造成鉛酸電池品質的隱憂。 The second is that although the epoxy resin has good bonding strength with the metal, the material of the acid-injecting cover plate 300 is usually a plastic material such as ABS or PP, and the bonding strength between the epoxy resin and the plastic material is poor, so that the package body 305 and the injection are made. The bonding strength between the acid cap plates 300 may not be able to withstand the chemical reaction pressure, which may cause the acid solution to overflow from the pole holes 303, the package body 305 and the grooves 302 to contaminate and corrode the electrical terminals 102 in the process. The use of the acid in the lower battery tank 200 is also likely to ooze out from this position, causing a concern about the quality of the lead-acid battery.
因此,如何改善傳統鉛酸電池封裝方式中長期存在有接電端子易受到酸液污染、以及封裝體密封結構不穩固的缺失,將是本發明人所欲解決之問題。 Therefore, how to improve the long-term existence of the conventional lead-acid battery packaging method is that the electrical terminal is susceptible to acid contamination and the sealing structure of the package is not stable, which will be solved by the inventors.
