technical field

The invention relates to the field of automatic testing, in particular to a device for automatic testing of a specific biaxial flipping structure.

Background technique

The double-axis turning structure has two rotating shafts, and the device connected by this rotating shaft can realize more flexible and diverse structural forms than the device connected by the ordinary single-rotating shaft structure. Therefore, the double-axis flip structure is widely used in modern electromechanical product devices, such as notebook computer products that use a double-axis hinge as a screen hinge component. But on the other hand, the flexible and diverse motion characteristics of the biaxial flip structure and the electromechanical devices formed by it greatly increase the difficulty of automatic testing of its structure, reliability and other performance.

Patent ZL201410224644.9 provides a method of using an industrial mechanical arm to perform torque on-line testing on the rotating shaft of a computer product. However, in this method, the rotating shaft of the computer product is located on the same side of the keyboard and the screen, and its motion is generally a reciprocating rotational motion.

For the case where the double-axis flip structure is located in the middle of the keyboard and the screen, if the distance between the two axes of the double-axis flip structure is large, its motion includes not only the basic reciprocating rotation motion, but also more diverse possible forms. However, there is a lack of corresponding methods and tools for the automated testing of this specific biaxial flipping structure.
