[0081] Working principle:

[0082] The present application adopts the method of automatic material feeding of belt conveyor line 1. When the laptop computer 9 to be tested is loaded, it is scanned. The system automatically matches the keyboard template according to the device model information of the laptop computer 9 read by the scanned code, and is transported to the detection position by belt conveyor line 1, triggering the transmitting photoelectric sensor 2, and the belt conveyor line 1 stops running. The six-axis manipulator 3 carries the gripper 4 and moves to the top of the laptop computer 9. The industrial camera 5 takes a picture of the laptop computer 9 and locates it. The relative position between the laptop keyboard and the gripper 4 is calculated. At the same time, the photographed picture is compared with the keyboard template to detect whether the keyboard has defects such as missing keys, wrong keys, and paint peeling on the keys. The laser ranging sensor 6 then measures the relative heights of the three positions on the laptop keyboard surface, determines a surface (keyboard surface) based on the three points, and calculates the angle between the laptop keyboard and the sixth flange axis of the six-axis manipulator 3. The six-axis manipulator 3 adjusts the posture of the gripper 4 so that the probe plane of the probe component 7-2-1 is parallel to the keyboard surface. After the posture adjustment is completed, the system controls the probe component 7 to be probed. -2-1 and Fn key pressure head detection component 7-1 rise along the Z direction to ensure that the Z-direction roller detection component 7-3 is at the lowest point. The six-axis manipulator 3 carries the gripper 4 to move to the roller detection height. Starting from the ESC key, it scrolls and presses the keys row by row from left to right to detect whether there is a string key defect on the keyboard. After the Z-direction roller detection component 7-3 completes the detection, the system controls all probe components 7-2-1 to descend along the Z axis to ensure that the Z-direction roller detection component 7-3 is higher than the probe component 7-2-1 and the Fn key pressure head detection component 7-1. Then, the notebook keyboard is inspected. The notebook keyboard consists of six rows of keys. The probe component 7-2-1 has three rows and six probes. The first, third, and fifth rows of keys are detected first. The combination of keys can be detected by pressing the Fn key pressure head detection component 7-1 and other probe components 7-2-1 in combination. Then, the gripper 4 is moved to detect the second, fourth, and sixth rows of the keyboard. After the detection is completed, the six-axis manipulator 3 moves to a safe position, and the system outputs the detection results and defect types.
