Problems solved by technology

During the testing process, different testing procedures need to be equipped with different testing equipment, which leads to relatively high costs; moreover, more testing stations need to be equipped with more testing personnel, which will also increase the testing cost
In addition, in the two procedures of the keyboard test, the test fixtures of each test procedure are relatively complicated, which increases some uncertain influencing factors and increases the measurement error
[0005] It can be seen that, using the existing keyboard testing equipment to realize the keyboard test, the test time is relatively long and the cost is relatively high

Abstract

The invention relates to a keyboard testing system, which includes a host computer, a display control device and at least one set of data acquisition equipment; the data acquisition equipment is used to convert the collected key value and resistance value of the keyboard connection key into connection key information Afterwards, send to host computer; Said host computer is used for detecting whether the button resistance value is greater than the standard resistance value, stores and splits the screen and displays the connected button key value, resistance value and detection result from each data acquisition device; the data acquisition device includes Data acquisition module, electrical control module and flexible circuit board connector. The system of the invention has the characteristics of short test time, small error and low cost, and can be widely used in electronic products with keyboards.

Description

technical field [0001] The invention relates to testing technology, in particular to a keyboard testing system. Background technique [0002] At present, the keyboard is carried out function test, common way is: the first step, test the on-off of each button on the keyboard to be tested, to guarantee that each button can work normally; The second step, test keyboard flexible circuit board (FPC, The resistance of each button on the Flexible Printed Circuit), and judge whether the resistance value of each button reaches the set normal range. [0003] For the on-off test of each key in the first step, the existing method is: the keyboard to be tested is directly connected to the computer, or the keyboard to be tested is fixed on a keyboard fixture with a processing chip, and the operation of each key is verified by key operation. on and off. In this way, each continuity test station needs to be equipped with a computer or keyboard fixture. For the test of the resistance valu...
