本发明的实施例二为：
与上述实施例一的区别在于，对预设涂胶区域做了进一步改进，具体为：
涂胶前，将所述预设涂胶区域划分多个子区域，在每个所述子区域内放置一个剥离件且所述剥离件至少一端延伸至子区域外；
对所有子区域进行涂覆胶水以使所述胶水覆盖所述剥离件位于每个子区域内的部分；
涂胶后，在位于每个所述子区域的胶水表面粘附电芯。
优选的，将每个所述子区域沿一方向再次划分为第一区域和第二区域，且第一区域的面积小于第二区域的面积；
将所述剥离件置于所述第一区域内；将所述电芯粘附在位于所述第二区域的胶水表面上。
具体的，将所述预设涂胶区域沿一方向划分多个子区域，每个子区域的形状、面积均相等，且每个子区域内设置有一个剥离件，且每个剥离件的相对两端均延伸至涂胶区域外。每个子区域均固定有相同数量的电芯，当某个子区域内的电芯需要拆卸时，只需拖拽该子区域内的剥离件对胶水层进行切割，从而实现单独对该子区域内的电芯进行拆卸的效果，提高了维护效率。
综上所述，本发明提供的一种具有脱胶功能的涂胶方法，在固定电芯的同时，通过提前将钢丝制成的剥离件预埋于电箱的底壁和胶水层之间的方式，在后续电芯需要拆卸时，可以通过对钢丝沿一方向施加外力从而使得钢丝可以沿一方向切割胶水，便于实现电芯的脱胶。该具有脱胶功能的涂胶方式，不仅避免了强力拆卸电芯造成芯体的损坏，同时可以省力快捷地将电芯和电箱完整的分离，从而可以将多个电箱拆卸出的电芯进行集中回收和修复，实现了维护意义。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
