Apparatus and method for detecting mounting state of light pipe in terminal

An apparatus for detecting a mounting state of a light pipe in a terminal, comprising:

• a fixture, wherein the fixture is configured to support a terminal housing, a light inlet path is formed in the fixture, an opening of the light inlet path exposed to the fixture is opposite to a mounting position of the light pipe in the terminal housing, and the light inlet path is configured to allow light transmitted by the light pipe to pass through;
• a detection light source, wherein the detection light source is disposed above the fixture, and is configured to emit detection light to the light pipe;
• and
• a light detection module, wherein the light detection module is disposed in the fixture, wherein the light detection module comprises a detection module including at least a first chip that is located opposite to the opening of the light inlet path and exposed to the fixture, a data processor, and an output module, and wherein the light detection module is configured to:
• receive, through the light inlet path, the detection light emitted from the detection light source;
• obtain, by the first chip, a first luminous flux value of the detection light emitted into the fixture through the light inlet path in a principal axis direction of the light inlet path;
• compare the first luminous flux value with a first threshold and a second threshold to determine a comparison result;
• and
• output a signal indicating a mounting state of the light pipe based on the comparison result, wherein the mounting state of the light pipe is one of:
• the light pipe is properly mounted, the mounting position of the light pipe is deviated, or the light pipe is not mounted,
• wherein when the first luminous flux value is greater than or equal to the first threshold and is less than or equal to the second threshold, the mounting state of the light pipe is that the light pipe is properly mounted;
• wherein when the first luminous flux value is less than the first threshold, the mounting state of the light pipe is that the mounting position of the light pipe is deviated;
• and
• wherein when the first luminous flux value is greater than the second threshold, the mounting state of the light pipe is that the light pipe is not mounted.
