Problems solved by technology

[0003] The earliest manual testing was performed manually. Not only is the efficiency extremely low, but also the misjudgment rate is very high due to the large human differences.
Some test devices that appeared after that were published as Chinese Invention Patent Application Publication No. 1257241 on June 21, 2000, Chinese Invention Patent Application Publication No. 1258034 on June 28, 2000, and Chinese Invention Patent Application Publication No. Invention Patent Application Publication No. 1512189A, it is very inconvenient to use due to the need to reprogram to test different products, and more importantly, the pressing force of the electronic product test cannot be accurately measured, and the pressing force cannot be accurately adjusted. Ability to monitor and record test status unattended
During the test process, the test results are often inaccurate or incomplete due to these reasons

Embodiment Construction

[0027] Please follow figure 1 As shown, the button and touch screen test device includes: a test frame 10, a control system 20 and a fixture mechanism 30

[0028] The present invention also discloses a method that can display the strength of the test to trace the source of the value and monitor the test state. The steps include:

[0029] 1) Install sensor A on the pressing head, and connect sensor A to the PLC; install sensor B on the test bench, and connect sensor B to the PLC.

[0030] 2) Test the buttons or touch screen of electronic products.

[0031] 3) Program in the PLC to convert the signal output by the force of the sensor A into data and function graphic display.

[0032] 4) Test whether the button or touch screen is effective or whether the electronic product is fixed firmly, and continue the test or stop the alarm according to the judgment result.

[0033] 5) Record test data.

[0034] When an exception occurs in the test, its processing steps further include t...

Abstract

The invention relates to a test device for keys and touch screens and is used for testing keys and touch screens of an electronic produce, comprising: a test jig which comprises a pneumatic component to be pressed, a clamping device for holding the pneumatic component and elevating mechanism for adjusting the height of the pneumatic component, with the pneumatic component comprising an air cylinder, an adjusting valve for adjusting pressure and an air cylinder end component comprising a replaceable pressed head and a sensor A; a control system which comprises a programmable controller PLC, an alarming system, a display system and a circuit connecting device; a clamp device comprising a test board and a sensor B. The invention also discloses a method for displaying the test degree to achieve measurement traceability and for monitoring the testing state, comprising the following steps of: (1) displaying the pressing force in form of data and functional digraph; (2) testing validity of the keys and the screen and the firmness of the electronic produce for further continuous test or stopping to give an alarm; (3) recording all data during the test process.

Description

【Technical field】 [0001] The invention relates to a button and touch screen test device, which is used for the button and touch screen test of electronic products. 【Background technique】 [0002] At present, keyboards and touch screens have been widely used in electronic products as peripheral devices for data and control command input. Therefore, the quality of keys and touch screens directly affects the use of electronic products. In the development of electronic products, keys and touch screens reliability testing is essential. [0003] The earliest manual testing was performed manually. Not only is the efficiency extremely low, but also the misjudgment rate is very high due to the large human differences. Some test devices that appeared after that were published as Chinese Invention Patent Application Publication No. 1257241 on June 21, 2000, Chinese Invention Patent Application Publication No. 1258034 on June 28, 2000, and Chinese Invention Patent Application Publicati...
