[0035] It should be noted that, in this embodiment, after the power adapter is assembled, the third conveying component 9, through the second XYZ axis motion module 901, drives the second cylinder finger 905 to move freely in the X-axis, Y-axis, and Z-axis directions, and through the drive shaft of the fourth drive motor 903, drives the second coupling 904 and the second cylinder finger 905 to rotate, so as to adjust to a suitable angle to clamp the assembled power adapter and place it on the top of the power adapter support block 906; at this time, the X-axis motion module 908 moves the third drive cylinder 909 to a position close to the power adapter support block 906, and the third drive cylinder 909 adjusts the sixth drive motor 910 and the fourth cylinder finger 911 to the same height as the power adapter support block 906 through its own extension and retraction. Then, the fourth cylinder finger 911 rotates synchronously with the drive shaft of the sixth drive motor 910, adjusting the fourth cylinder finger 911 to a suitable angle to grip the power adapter.

[0037] It should also be noted that the principle of the ultrasonic test is as follows: when the assembled power adapter is moved to the ultrasonic machine 1001, the ultrasonic machine 1001 emits high-frequency ultrasonic pulses to the power adapter. Some of the sound waves are reflected back to form echoes. The ultrasonic machine 1001 determines whether there are defects in the assembly of the power adapter by calculating the time difference and amplitude of the echo return. The principle of the visual test is as follows: the miniature camera first acquires a high-resolution image of the surface of the power adapter under specific light conditions. Then, the acquired image is preprocessed (such as noise reduction and contrast enhancement), feature extraction (such as edges, contours, and colors), gap recognition, and gap width calculation and comparison are performed by a visual detection algorithm to determine whether there are defects in the assembly of the power adapter. The visual detection algorithm is a commonly used algorithm in the field of computer vision and belongs to the prior art, so it will not be described in detail here.
