[0008] Step S4: the light source installation module installs the light source on the third semi-finished product to obtain a finished product, and detects the luminous quality of the finished product through the fourth detection unit of the detection module to determine whether the luminous quality of the current finished product meets the preset requirements; if so, it is transmitted to a qualified area through the transmission module; otherwise, the fourth semi-finished product is transmitted to a fourth unqualified area through the transmission module, and the pass rate of the light source installation module is obtained by counting the number of finished products in the fourth unqualified area.

[0009] As a further preferred technical solution of the above technical solution, when detecting the luminous quality, the light source is turned on so that the light emitted by the light source passes through the transparent first semi-finished product, the hollow pattern carved on the shading strip and the translucent paint in sequence, so that the emitted light presents a pattern shape, and the luminous quality of the final product is judged by detecting the matching degree between the presented pattern shape and the carved hollow pattern.

[0010] As a further preferred technical solution of the above technical solution, for the matching degree between the pattern shape and the carved hollow pattern, wherein:
