[0029] As Figures 1 to 3 shown, the present utility model discloses an automatic appearance detection device 100 for a mobile phone charger, including a detection bracket 11.

[0034] Please continue to refer to Figure 4 In this application, the feeding mechanism 20 is used to grab the charger to be tested and move it to the corresponding position of the jig mechanism 30.

The third driving slide 53 is connected to the CCD camera 41 and can drive the CCD camera 41 to move in a direction closer to or farther from the jig mechanism 30. In this application, the driving directions of the third driving slide 53 and the first driving slide 51 are the same, and the first direction and the second direction are distributed at a right angle.

[0041] To ensure the driving accuracy of the driving mechanism 50, a laser rangefinder 54 can be provided at the output end of the third driving slide 53 to ensure the driving accuracy of the CCD camera 41.
