The invention relates to a spraying process of an automobile light-emitting grille, the light-emitting grille and a grille assembly, and relates to the technical field of automobile accessories, and the spraying process of the light-emitting grille comprises the following steps that a main body PC layer is obtained through injection molding; the UV varnish layer is sprayed on the front surface of the main body PC layer, and the film thickness of the UV varnish layer is controlled within the minimum film forming thickness range through ultraviolet light treatment; a colored paint layer is sprayed on the back surface of the main body PC layer, and drying treatment is performed; a preset pattern is engraved on the back face of the colored paint layer through laser, the preset pattern on the engraved face forms a light-transmitting area, and the non-engraved face forms a light-proof area; and spraying the inner varnish layer on the back surface of the colored paint layer, and drying. According to the spraying process of the light-emitting grating, the light-emitting grating and the grating assembly, the problems that in the prior art, an ink layer is poor in corrosion resistance and aging resistance, stone impact resistance is poor due to the fact that the hardness of a hardened coating is low, and light transmittance and signal passing ability are poor due to the fact that the thickness of the hardened coating is large are solved.

    本申请涉及一种汽车发光格栅的喷涂工艺、发光格栅及格栅组件,涉及汽车配件技术领域,发光格栅的喷涂工艺,包含以下步骤:注塑成型得到主体PC层;主体PC层正面喷涂UV清漆层,并经紫外光处理,控制UV清漆层的膜厚在最小成膜厚度范围内;主体PC层背面喷涂色漆层,并进行烘干处理;在色漆层背面进行激光镭射刻印出预设图案,刻印面的预设图案形成透光区,非刻印面形成不透光区;色漆层背面喷涂内层清漆层,并进行烘干处理。本申请的发光格栅的喷涂工艺、发光格栅及格栅组件,解决现有技术中油墨层抗腐蚀性差抗老化性能差、以及硬化涂层的硬度低导致抗石击效力差、以及硬化涂层厚度大导致透光性差和信号通过性差的问题。
