[0002] Flaw detection of mobile phone middle frames usually refers to non-destructive testing of mobile phone casings to ensure the integrity and safety of their welded parts. Common mobile phone frame flaw detection methods include magnetic particle flaw detection and ultrasonic flaw detection. Magnetic particle flaw detection is a commonly used non-destructive testing method that utilizes the magnetic properties of ferromagnetic materials under the action of a magnetic field for detection. Defects inside or on the surface can be inspected through magnetic particle flaw detection. This method can detect surface cracks, inclusions, pores, etc. However, during the flaw detection process, it is difficult to clean the magnetic suspension liquid, which affects the accuracy of flaw detection. Ultrasonic flaw detection, on the other hand, utilizes the propagation and reflection characteristics of ultrasonic waves in materials to detect material defects. However, in the prior art, the general method is a handheld flaw detector, and manual contact is used to detect the mobile phone middle frame, resulting in low efficiency.
