Description
本發明係有關於一種電池極板板頭清潔方法，尤其是指以雷射進行清潔電池極板板頭的方法。 The present invention relates to a method for cleaning a battery plate head, and more particularly to a method for cleaning a battery plate head by laser.
市面上所見的蓄電池，也可稱為濕式電池或免加水保養或電瓶，它主要係利用極板與電解液起化學作用，而將電能轉換成化學能並予以儲存，並且在使用時將化學能釋放再轉換成電能者。 The battery seen on the market, also known as wet battery or water-free maintenance or battery, is mainly used to chemically convert the electric energy into electrolyte energy by using the plate and the electrolyte, and will be chemically used when used. Can be released and converted into electricity.
其中，蓄電池中包含許多正、負極交錯排列的極板，而且為了分別使這些正、負極板之間能正確的相互橋接，每一片正極板上及負極板上皆會設置一板頭，再於每一片正極板的板頭上以鉛橋並連，每一片負極板的板頭上也以鉛橋並連，使每一片正極板間及每一片負極板間分別透過鉛橋的並連而連接。 Wherein, the battery includes a plurality of plates in which the positive and negative electrodes are alternately arranged, and in order to properly bridge the positive and negative plates, a positive plate is disposed on each of the positive and negative plates, and then The front of each positive plate is connected by a lead bridge, and the front of each negative plate is also connected by a lead bridge, so that each positive plate and each negative plate are connected by a lead bridge.
然而，在串焊的過程中，板頭的潔淨與否影響了後續鉛橋的焊接(熔接)與導電效果，因此，業者再進行板頭的鉛橋焊接工序之 前，會先對板頭進行清潔，以去除板頭表面的污垢或表面產生的氧化物、塵屑。 However, in the process of string welding, the cleanness of the plate head affects the welding (welding) and the conductive effect of the subsequent lead bridge. Therefore, the manufacturer performs the lead bridge welding process of the plate head. Before, the board head will be cleaned first to remove dirt on the surface of the board head or oxides and dust generated on the surface.
傳統的板頭清潔方式是先將陽極板與陰極板各別堆疊，再逐一以人工一片一片以鋼刷直接清潔板頭表面，於清潔完畢後再將陽極板頭、隔板、陰極板頭交錯堆疊，但此一清潔方式會產生如下缺點： The traditional method of cleaning the plate head is to first stack the anode plate and the cathode plate separately, and then directly clean the surface of the plate head with a steel brush one by one, and then interlace the anode plate head, the separator plate and the cathode plate head after cleaning. Stacking, but this cleaning method has the following disadvantages:
1、因為採用以鋼刷直接刷洗板頭表面，故容易因為施力大小不同而使鋼刷刷除板頭表面時受力不同，並於板頭表面形成不同深淺的刷除紋路，容易使板頭厚度越來越薄。 1. Because the surface of the plate head is directly scrubbed with a steel brush, it is easy to make the steel brush brush the surface of the plate head differently due to the different force applied, and form different shades of the brush on the surface of the plate head, which is easy to make the plate. The thickness of the head is getting thinner.
2、因為採用以鋼刷直接刷洗板頭表面，所以會因為施力大小不同而使板頭表面的清潔度不一，以致於在鉛橋焊接後由於清潔度不佳之處產生間隙，進而影響極板之間的熱量與能源的傳導係數。 2. Because the surface of the plate head is directly scrubbed with a steel brush, the cleanliness of the surface of the plate head may be different due to the different force applied, so that the gap is generated after the lead bridge is welded due to poor cleanliness, thereby affecting the pole. The heat transfer between the plates and the energy transfer coefficient.
3、因為採用人工以鋼刷直接刷洗板頭表面，不僅費工、費時，所需的人工成本也較高。 3. Because manual brushing of the surface of the board with a steel brush is laborious and time consuming, the labor cost required is also high.
4、因為是以鋼刷，因此在刷過程中，鋼刷因為和板頭摩擦而產生鉛粉塵的情形，危險環境與人體，必需要設置集塵設施。 4. Because it is a steel brush, in the process of brushing, the steel brush produces lead dust due to friction with the plate head. In a dangerous environment and the human body, it is necessary to set up a dust collecting facility.
5、傳統的板頭清潔方式是先將陽極板與陰極板各別堆疊，再逐一以人工一片一片以鋼刷直接清潔板頭表面，於清潔完畢後再 將陽極板頭、陰極板頭交錯堆疊，因此清潔工序較為繁複，且浪費工時。 5, the traditional method of cleaning the board head is to first stack the anode plate and the cathode plate separately, and then manually clean the surface of the plate head with a steel brush one by one, after cleaning, The anode plate head and the cathode plate head are alternately stacked, so the cleaning process is complicated and wastes man-hours.

為令本發明所運用之技術內容、發明目的及其達成之功效有更完整且清楚的揭露，茲於下詳細說明之，並請一併參閱所揭之圖式及圖號：本發明之電池極板板頭清潔方法，主要係在電池極板的板頭在進行鉛橋焊接之前，先進行板頭的清潔步驟，使板頭在經過清潔後能減少附著於表面的污垢或表面產生的氧化物、塵屑，而利於與鉛橋與板頭的結合，並避免因為表面的污垢或表面產生的氧化物、塵屑而在鉛橋焊接過程中產生間隙進而導致熱量與能源的傳導係數下降之問題。 For a more complete and clear disclosure of the technical content, the purpose of the invention and the effects thereof achieved by the present invention, as will be described in detail below, please refer to the drawings and drawings of the present invention: the battery of the present invention. The method of cleaning the plate head is mainly to clean the head of the head of the battery plate before the lead bridge is welded, so that the head can be cleaned to reduce the dirt or surface oxidation caused by the surface. Material, dust, and facilitate the combination with the lead bridge and the plate head, and avoid the gap between the lead bridge welding process due to the dirt on the surface or the oxides and dust generated on the surface, resulting in a decrease in the conduction coefficient of heat and energy. problem.
本發明之電池極板板頭清潔方法，係以雷射進行電池極板之板頭的表面處理，使所述板頭表面因為除去附著的污垢或表面產生的氧化物、塵屑，而在所述板頭表面產生除垢後微結構，這些除垢後微結構的深度為0.01~0.1mm，而其密度則為0.01~0.05mm2。而本發明在進行電池極板之板頭表面處理的清潔步驟前，係先將各別堆疊的陽極板與陰極板以及隔板予以交錯堆疊，即在陽極板與陰極板之間堆疊隔板，接著使用雷射清潔陽極板與陰極板的板頭。其中，本發明的清潔方法並不以單組堆疊之陽極板-隔板-陰極板為限，只要將陽極板、陰極板以及隔板交錯堆疊皆能進行清潔。 The method for cleaning the battery plate head of the present invention is to perform surface treatment on the head of the battery plate by laser, so that the surface of the plate head is removed by removing the adhered dirt or oxides and dust generated on the surface. The microstructure of the surface of the head is descaled. The depth of the microstructure after descaling is 0.01~0.1mm, and the density is 0.01~0.05mm 2 . However, before the cleaning step of the surface treatment of the head of the battery plate, the present invention firstly stacks the stacked anode plates and the cathode plates and the separators, that is, stacks the separator between the anode plate and the cathode plate. The anode and cathode plates are then cleaned using a laser. Wherein, the cleaning method of the present invention is not limited to a single set of stacked anode plate-separator-cathode plates, as long as the anode plate, the cathode plate and the separator are alternately stacked for cleaning.
請參看第一圖，係揭示未進行表面清潔(表面處理)的板頭表面情形，在該圖中板頭表面附著污垢或表面產生的氧化物、塵屑， 而無金屬亮光；請參看第二圖，係揭示以能在板頭表面產生深度為0.01mm的除垢後微結構的雷射能量強度清潔(表面處理)板頭表面，其清潔後頭表面的情形，在該圖中板頭表面附著的污垢或表面產生的氧化物、塵屑因被去除，而呈現金屬亮光；請參看第三圖，係揭示以能在板頭表面產生深度為0.05mm的除垢後微結構的雷射能量強度清潔(表面處理)板頭表面，其清潔後頭表面的情形，在該圖中板頭表面附著的污垢或表面產生的氧化物、塵屑因被去除，而呈現金屬亮光，第四圖為第三圖的局部放大圖；請參看第五圖，係揭示以能在板頭表面產生深度為0.1mm的除垢後微結構的雷射能量強度清潔(表面處理)板頭表面，其清潔後頭表面的情形，在該圖中板頭表面雖去除了附著的污垢或表面產生的氧化物、塵屑，但因為雷射能量太強，造成碳化現象，反而無清潔效果。由第一圖~第五圖可知，雷射方式確實能將板頭表面的污垢或表面產生的氧化物、塵屑去除，惟雷射能量強度必須設定避免板頭表面產生碳化現象。 Referring to the first figure, it is revealed that the surface of the head surface is not subjected to surface cleaning (surface treatment), in which the surface of the head is attached with dirt or oxides and dust generated on the surface. Without metal light; please refer to the second figure, which reveals the surface of the head surface of the laser energy cleaning (surface treatment) of the microstructure after descaling with a depth of 0.01 mm on the surface of the head. In the figure, the dirt or dust on the surface of the head surface is removed, and the metal light is removed. Referring to the third figure, it is revealed that a depth of 0.05 mm can be generated on the surface of the head. The laser energy intensity of the post-scale microstructure cleans (surfaces) the surface of the head, which is the condition of the head surface after cleaning. In this figure, the dirt or surface oxides and dust generated on the surface of the head are removed. The metal is bright, and the fourth is a partial enlarged view of the third figure; see the fifth figure, which reveals the laser energy intensity cleaning (surface treatment) of the microstructure after descaling with a depth of 0.1 mm on the surface of the head. The surface of the head is cleaned after the surface of the head. In the figure, although the surface of the head is removed from the attached dirt or oxides and dust on the surface, the laser energy is too strong, resulting in carbonization, but no cleaning effect.It can be seen from the first to fifth figures that the laser method can remove the dirt on the surface of the board or the oxides and dust generated on the surface, but the intensity of the laser energy must be set to avoid carbonization on the surface of the board.
請參看第六圖，係揭示在板頭的其中一面進行雷射清潔，另一面未清潔除垢的外觀情形；請參看第七圖(A)，係揭示在板頭的其中一面進行雷射清潔，另一面未清潔除垢的切面情形，第七圖(B)揭示在第七圖(A)的狀態下進行鉛橋焊接後，極板板頭雷射清潔面與未清潔面的切面對照情形，第七圖(C)為第七圖(B)的放大圖，由第七圖(A)、(B)、(C)可清楚看到，極板板頭雷射清潔面進行鉛橋焊接後未產生間隙，而極板板頭未清潔面進 行鉛橋焊接後產生間隙。 Please refer to the sixth figure, which reveals the appearance of laser cleaning on one side of the head and the uncleaned appearance on the other side; see Figure 7 (A), which reveals laser cleaning on one side of the head. The other side is not cleaned and descaled, and the seventh figure (B) reveals the comparison between the clean surface of the plate head and the uncleaned surface after the lead bridge welding in the state of the seventh figure (A). The seventh figure (C) is an enlarged view of the seventh figure (B). It can be clearly seen from the seventh figure (A), (B), (C), and the lead plate head laser clean surface is subjected to lead bridge welding. There is no gap after the opening, and the plate head is not cleaned. A gap is created after the lead bridge is welded.
由於本發明係採用雷射清潔板頭表面，且雷射能量強度以清潔後板頭表面之除垢後微結構的深度0.01~0.1mm、密度0.01~0.05mm2為設定值，因此能使板頭表面的潔淨度一致，不會使板頭厚度越來越薄，並能大幅減少在以鉛橋焊接各個極片的板頭後所產生的間隙，避免影響極板之間的熱量與能源的傳導係數，而且不採用人工清潔，不僅省工、省時，所需的人工成本也較低，尤其在清潔過程中不會有掉屑的情形，不會影響板頭的潔淨性，不會產生粉塵，影響人體與環境。 Because the invention adopts laser to clean the surface of the plate head, and the laser energy intensity is set to a set value after the descaling of the surface of the plate head after cleaning, the depth of the microstructure is 0.01~0.1mm, and the density is 0.01~0.05mm 2 The cleanliness of the surface of the head is uniform, which will not make the thickness of the head thinner and thinner, and can greatly reduce the gap generated after welding the head of each pole piece with a lead bridge, and avoid affecting the heat and energy between the plates. Conduction coefficient, and does not use manual cleaning, not only saves labor, saves time, the labor cost required is also low, especially in the cleaning process, there will be no chipping, it will not affect the cleanliness of the plate head, and will not produce Dust, affecting the human body and the environment.
