Description

Notebook computer rotating shaft test equipment
Technical Field
The invention relates to the field of testing devices, and particularly discloses a notebook computer rotating shaft testing device.
Background
The notebook computer has similar structure with the desktop computer, but the notebook computer is popular because the notebook computer has the advantages of small volume, light weight, convenient carrying and the like, and can be carried about in both out work and travel, thereby being very convenient.
The screen and the keyboard of the notebook computer need to be frequently opened and closed so as to be convenient to use and carry. Therefore, in order to ensure the safety and reliability of the notebook computer in the use process, the finished product or semi-finished product of the notebook computer after the assembly of the rotating shaft is completed needs to be subjected to running-in and torsion adjustment tests.
In the prior art, running-in test of a rotating shaft of a notebook computer is mainly carried out by operating an automatic machine table, manually placing related components of the rotating shaft on a checking fixture, fixing one bracket of the rotating shaft, clamping the other bracket by a checking fixture cylinder, swinging back and forth for three times within a 360-degree range under the drive of a motor to carry out running-in action, and drawing torsion in the running-in process into a torsion curve graph to display and record in real time.
In the prior art, the torque force of the rotating shaft of the notebook computer is usually adjusted manually. And manually placing the device on a gauge of the torsion meter, fixing one bracket, clamping the other bracket by using the hanging rod, manually pulling the hanging rod, and visually judging the reading on the torsion meter. If the readings displayed on the torquemeter are in compliance, the product is removed and flowed to the next station. If the readings on the torquemeter are not in compliance with the specification, the torquemeter needs to be retested after the tightness of the nut is adjusted until the torquemeter is within the specification range.
In the prior art, the test on the rotating shaft of the notebook computer is divided into two independent sections of swing running-in action and torsion adjustment, and the two tests can not be effectively combined together, so that the labor cost is additionally increased, and the detection time is also increased. In addition, because the manual mode is adopted to adjust the torsion in the torsion measurement process, operators need to continuously swing, and the operators only need to judge by eyes, so that errors are easy to occur, the self-checking cannot be carried out, and meanwhile, the fatigue strength of the operators is increased.
