The present invention relates to a method of manufacturing a lead acid battery, which maintains a constant level of the lead acid battery to make the performance of the lead acid battery uniform.
일반적으로 납축전지는 각각 납과 산화납으로 이루어진 두 극판과 전해질인 황산 수용액 사이의 산화환원 반응에 의해 충전과 방전이 가능한 축전지이다. 이것은 복수의 양극과 음극판을 포함하고 있으며, 각각의 판들을 인접한 판들과 격리시키는 격리판과 함께 음극판과 양극판이 번갈아 배치된다. 이렇게 배치된 극판과 격리판 이외의 공간을 전해질인 황산수용액으로 채워져 있다.In general, a lead acid battery is a battery that can be charged and discharged by a redox reaction between two electrode plates made of lead and lead oxide, and an aqueous sulfuric acid solution. It includes a plurality of positive and negative plates, and the negative and positive plates are alternately arranged with a separator to isolate each plate from adjacent plates. The spaces other than the electrode plates and separator plates thus arranged are filled with sulfuric acid aqueous solution.
종래 납축전지의 제조에 있어서, 전기적 활성을 부여하는 화성(충전)공정이후 극판 표면에 가스(H2, O2) 및 거품이 존재하여 전해질인 황산의 양이 일정수준을 유지하지 못하고, 내부 파티션별로 황산의 레벨 차이를 보여 제품의 외관 및 성능면에서 균일한 제품을 생산하기 어렵고, 또한 이를 보완하는 특별한 기술이 없는 실정이다.In the manufacture of a conventional lead acid battery, gas (H2, O2) and bubbles are present on the surface of the electrode plate after the chemical conversion (charging) process of imparting electrical activity, and thus the amount of sulfuric acid as an electrolyte cannot be maintained at a constant level. It is difficult to produce a uniform product in terms of appearance and performance due to the level difference of and there is no special technology to compensate for this.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 발명은 화성(충전)공정을 거쳐 제조된 납축전지의 극판 표면에 가스와 거품이 존재하는 것을 방지하고, 납축전지의 각 전조내에 충전되는 전해질의 수위를 일정하게 유지하여 납축전지의 성능을 균일하게 할 수 있게 하는 납축전지의 제조방법을 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, the present invention is to prevent the presence of gas and bubbles on the surface of the electrode plate of the lead acid battery produced through the chemical conversion (charge) process, the charge in each precursor of the lead acid battery It is an object of the present invention to provide a method for manufacturing a lead acid battery, which maintains a constant level of an electrolyte to make the performance of a lead acid battery uniform.
본 발명은 상기와 같은 목적을 달성하기 위하여 다음과 같이 구성된다. 즉, 본 발명은 화성공정을 거친 납축전지를 진동 콘베이어상에서 납축전지에 진동을 가하여 극판 표면의 가스 및 거품을 제거하여 전해질의 레벨 저하 및 불균일성(황산의 비중 불균일)을 방지할 수 있게 하는 것에 특징을 둔 것이다. The present invention is configured as follows to achieve the above object. In other words, the present invention is characterized in that the lead-acid battery subjected to the chemical conversion process is subjected to vibration on the lead-acid battery on the vibrating conveyor to remove gas and bubbles on the surface of the electrode plate, thereby preventing the lowering of the electrolyte level and non-uniformity (non-uniformity of sulfuric acid). It is put.
이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예를 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;
납축전지의 제조는 크게 건식 제조방식과 습식 제조방식으로 나누어진다. 건식 제조방식은 납축전지 제조 메이커에서 납축전지의 내부에 전해액을 주액시키지 않은 상태로 출시된 후 사용자가 전해액을 직접 주액하는 방식이고, 습식 제조방식은 납축전지의 제조 공정 중에 전해액을 미리 주액하여 제품을 출시하는 방식이다.The production of lead acid batteries is largely divided into a dry manufacturing method and a wet manufacturing method. The dry manufacturing method is a method in which a lead acid battery manufacturer releases the electrolyte solution without pouring the electrolyte solution inside the lead acid battery, and the user directly injects the electrolyte solution. The wet manufacturing method injects the electrolyte solution in advance during the manufacturing process of the lead acid battery product. Is the way to release.
전해액의 주액은 1차로 전해액을 주액한 후 이를 쏟아 버린 제품에 2차 전해액을 주액한다.The electrolyte is poured into the first electrolyte after pouring the electrolyte into the product.
숙성완료된 극판(pbo)을 양극pbo2로, 음극pb로 변환시키는 화성(충전)공정에서 완전충전상태가 되고 난 후, 물이 전기분해 되어 양극에서는 산소(O2)가 음극에서는 수소(H2)가 발생되며, 이러한 가스는 제품 출시 후 충방전시에도 지속적으로 발생하게 된다. 또한 전해액 주액시 극판 내부의 공극률에 따라 주액량에 있어서 미세한 차이를 보이게 되며 주액방식(중력방식/압력차방식 등)의 차이에 따라 거품의 발생 정도가 달라져 최종적으로 전해액의 레벨편차를 유발시키게 되는 것이다.In the process of converting the matured pole plate (pbo) to the anode pbo2 and to the cathode pb, the water is electrolyzed and oxygen (O2) is generated at the anode and hydrogen (H2) at the cathode. These gases will continue to occur during charge and discharge after the product launch. In addition, there is a slight difference in the amount of pouring depending on the porosity inside the electrode plate during the electrolyte injection, and the degree of foaming varies according to the difference in the injection method (gravity method / pressure difference method, etc.), which finally causes the level deviation of the electrolyte solution. will be.
본 발명은 납축전지의 내부에 주액되는 전해액의 수위를 균일하게 유지시킴에 있어서, 전해액이 담겨지는 전조의 내부에서 발생되는 거품과 가스의 기포를 제거하여 전해액의 레벨편차를 줄일 수 있게 하는 것이다.In the present invention, in maintaining the level of the electrolyte solution injected into the lead acid battery uniformly, it is possible to reduce the level deviation of the electrolyte solution by removing the bubbles and gas bubbles generated in the inside of the precursor containing the electrolyte solution.
