[0090] Working principle:

Because the first row of function keys of the laptop computer are generally small keys, only the left, middle and right points need to be detected. The second to sixth rows are large keys, and the four corners and the center can be tested. Alternatively, only the center point can be detected according to actual needs. Because there are differences in the keys of each row, the X-direction adjustment mechanism 4 can be used to automatically adjust the position of the probe mechanism 5 according to the time it takes to complete the detection of each key, and the detection of the next key can be started to avoid waiting too long.

[0092] In addition, the adjustment of the X, Y and Z directions of the laptop keyboard detection gripper in the present application is adjusted by a manipulator, and the laptop keyboard detection gripper is mounted on the manipulator, and then the manipulator drives the laptop keyboard detection gripper to move in the X, Y and Z directions.
