[0017] Example 1
[0018] Such as figure 1 The shown detection method and detection device for the defects of the mobile phone housing include a laser transmitter 1, a motion module 2, a camera 3, and a filter 4. The laser transmitter 1 is arranged on the motion module 2, and The laser transmitter 1 is used to provide a laser source for detecting the mobile phone housing 5, the filter 4 is arranged along the light path direction of the reflection angle of the mobile phone housing 5, and a camera 3 is provided under the filter 4.
[0019] The laser transmitter 1 emits a horizontal laser light source directly onto the surface of the mobile phone housing 5 after passing through the filter, and the light is reflected by the mobile phone housing 5 and finally enters the shooting area of the camera 3.
[0020] The wavelength emitted by the laser transmitter 1 is 350-450 nm.
[0021] The incident angle between the light emitted by the laser transmitter 1 and the glass screen 5 ranges from...
