Embodiment 1

[0079] see Figure 1-Figure 5 , the general computer product testing system includes a mechanical arm 1, a mechanical arm controller 2, a force sensor 3, an end tool 4, a fixture 5, a reference table 6 and a main control computer 7, and is characterized in that: the mechanical arm 1 has Space multi-degree-of-freedom movement capability is used to perform test actions; the mechanical arm controller 2 is connected to control the movement of the mechanical arm 1; the force sensor 3 is installed on the flange at the end of the mechanical arm 1, and the force sensor 3 has parameters for spatial force and synchronous measurement of torque parameters; the end tool 4 is installed on the force sensor 3, and the end tool 4 has different forms according to different types of tests, including driving and electric control devices; the fixture 5 is used to install and fix the computer product under test; There are equidistant through-holes or threaded holes arrayed on the reference table 6,...

Embodiment 2

[0081] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0082] The clamp 5 is a modular and flexible clamp for clamping and fixing computer products. It is composed of several clamp units. Each clamp unit can clamp the side structure of the notebook computer. It is installed horizontally on the reference platform 6 at any relative position, so as to adapt to the clamping of computer products of different sizes.

[0083] The side profile of the clamp unit is C-shaped, and is composed of a detachable upper module 51, a middle module 52 and a lower module 53; the middle module 52 supports and connects the upper module 51 and the lower module 53, and the lower module 53 positions the clamp unit Fixed on the reference platform 6. The upper module 51 is distributed with a plurality of clamping modules 54, and these modules 54 compress the side of the computer product in the form of dispersed force points; the connection between t...

Embodiment 3

[0085] see Figure 6-Figure 12 , this general computer product test method, adopts above-mentioned test system to carry out test, is characterized in that: generally suitable for the test of different types of test task of computer product aspect reliability in use, test method is divided into four steps: 1, calculation method decomposition , 2. Test action planning, 3. Intermediate parameter measurement, 4. Test action operation and result processing.

[0086] The decomposition of the calculation method of the first step is: the calculation from the original force data to the observation force data is decomposed into two steps, the decomposition calculation is completed from the original force data to the contact force data calculation, and the decomposition calculation is completed from the contact force data to the observation force data calculation; the calculation method of decomposition calculation 1 is realized through two-step compensation, which are the end tool 4...

Abstract

The invention provides a universal computer product testing system and method. The system comprises a mechanical arm, a mechanical arm controller, a force sensor, a terminal tool, a clamp, a standard table facet and a master control computer. The clamp is formed by a plurality of clamp units with C-shaped contour characteristics. The clamp has the advantages of being capable of performing suspension clamping, provided with various combination changes, high in adjusting flexibility and good in rigidity and is matched with the mechanical arm, the force sensor and the terminal tool to complete various tests, so that function and expansibility defects of traditional test equipment are overcome. The method comprises the steps of first, calculation method decomposition; second, test action planning; third, intermediate parameter measurement; fourth, test action running and result processing. By calculation process decomposition, parameter measurement method base establishment and the like, the testing method can be applied to various test tasks of computer product use reliability universally, and test results are accurate and credible.

Description

technical field [0001] The invention relates to the field of computer product testing, in particular to a general computer product testing system and method. Background technique [0002] Laptops, tablets, and mobile phone shafts, display touch screens, keyboards, etc. are important components for direct physical interaction between users and computer products. Their reliability directly affects product performance and quality and user experience. Therefore, the research and development of the above products has always been And use the core of reliability testing in the production phase. For example, the notebook computer hinge not only provides support for the rotation of the notebook display screen, but also provides frictional torque for the fixation of the display screen at a certain rotation angle, and at the same time protects the data lines connecting the notebook computer display screen and keyboard; while the touch screen is both a graphic display The device is als...
