Backlight substrate assembling method and equipment

The invention relates to a backlight substrate assembling method and equipment, and relates to the field of backlight substrate assembly.The backlight substrate assembling method comprises the following steps that a shell which is not clamped is installed on a reflecting plate in advance, the reflecting plate and the shell are placed on a first workpiece storage table, and a light guide part is placed on a second workpiece storage table; the first suction cup mechanical arm moves the reflecting plate and the shell on the first workpiece storage table to the machining rotary disc; the light guide piece on the second workpiece storage table is conveyed to the machining rotary table through a second suction cup mechanical arm and covers the reflecting plate; the machining rotary table conveys a workpiece to be machined to the clamping and flattening device, the clamping and flattening device flattens and compresses the diffusion sheet and the brightness enhancement sheet on the light guide piece, meanwhile, shel
