The invention discloses an automobile B column assembling structure which comprises a support and a decorative plate, one part of the support is welded to the decorative plate through an ultrasonic plane welding technology, the other part of the support is bonded to the decorative plate through a double-face bonding sheet, a metal embedded part is arranged in the support, and a connecting piece is connected with the metal embedded part from the inner side of an automobile body. A transparent paint layer is arranged on the surface of the decorative plate, and the paint layer is formed through the following steps that the decorative plate is horizontally placed on a conveying belt of an assembly line to move forwards; linear paint flows downwards from a downward long-strip-shaped paint outlet hole in a paint spraying bracket, and uniformly falls on the surface of the decorative plate to form a paint film; and the decorative plate with the paint film on the surface is baked and cured into a paint layer. According to the automobile B-column decoration plate, the support and the decoration plate can be conveniently machined and manufactured, the support and the decoration plate can be conveniently assembled and connected, the production efficiency of the automobile B-column decoration plate can be improved, the overall strength of the automobile B-column decoration plate can be guaranteed, and meanwhile the surface quality of the automobile B-column decoration plate can be improved.

    本发明公开了一种汽车B柱装配结构,包括支架和装饰板,支架的一部分通过超声波平面焊接工艺与装饰板相焊接,支架的另一部分通过双面粘结片与装饰板相粘接,支架内设有金属预埋件,连接件从车身内测与金属预埋件相连接,在装饰板表面设有透明的油漆层,所述油漆层采用如下步骤形成:将装饰板水平地放置在流水线的传输带上向前移动;一淋漆支架上向下的长条形出漆孔向下流出线状的油漆,并均匀地落到装饰板表面形成漆膜;表面具有漆膜的装饰板经过烘烤后固化为油漆层。本发明既方便支架和装饰板的加工制造,又方便支架和装饰板的装配连接,进而有利于提升汽车B柱饰板的生产效率,并确保其整体强度,同时可提升汽车B柱饰板的表面品质。
