Abstract
The utility model discloses an auto-test system used for mobile phone keyboard. The system includes a test clamp and a test host. A mobile phone to be tested is placed on the test clamp which is provided with a pressing needle matching with the mainboard keyboard of the mobile phone to be tested. The test host includes an electronic switch and a master control MCU. The control signal input terminal of the electronic switch is connected to the master control MCU, and the other terminal of the electronic switch is connected to the pressing needle. The master control MCU is connected to the mainboard of the mobile phone to be tested through a serial port bus. The signals are sent between the mainboard of the mobile phone to be tested and the master control MCU through the serial port bus, and the master control MCU controls the electronic switch to switch on or switch off successively; and thus the pressing needle controlled by the electronic switch acts on the mainboard keyboard of the mobile phone to be tested. The test system enables the automation of cell phone mainboard keyboard tests; and the test cost is reduced and the accuracy and the reliability of test results are raised.
Description
Technical field
The utility model relates to a kind of Auto-Test System, particularly relates to a kind of cell phone keyboard Auto-Test System.
Background technology
Mobile phone, has now become indispensable communication tool in people's daily life, and in the time using mobile phone, people transmit instruction by cell phone keyboard to interior of mobile phone, thereby complete the realization of corresponding function.But along with the high speed development of electronic technology, cell phone mainboard is more and more less, production difficulty is increasing, especially for not only thin but also long signal lead of cell phone mainboard upper keyboard, in SMT process, be more prone to loose contact situation, producer has a strong impact on mobile phone quality, therefore before mobile phone installation, must test to cell phone mainboard button situation.
The test mode adopting is at present that tested cell phone mainboard is fixed in the test fixture that thimble is housed, by the manual enter key looping test of tester interface, this interface display goes out all buttons on tested cell phone mainboard, tester needs all buttons to press successively, judges the contact situation of button.This test macro can be found the button of loose contact, but tester's workload is relatively large, causes testing efficiency low, and testing cost is high; Meanwhile, due to the carelessness of tester in operating process, exist leak by and mistake the phenomenon such as press, make the accuracy of test result and reliability lower.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of test macro of realizing automation detection of handset mainboard keyboard is provided, this system employs electronic switch control thimble, thereby realize automation and the intellectuality of cell phone mainboard keyboard test, and the testing efficiency of this system is high, test speed is fast, test result accuracy and reliability high.
The utility model is achieved through the following technical solutions: a kind of cell phone keyboard Auto-Test System, it comprises test fixture and Test Host, tested cell phone mainboard is placed on test fixture, and the thimble matching with tested cell phone mainboard keyboard is housed on test fixture; Test Host comprises electronic switch and main control MCU, and the control signal input of electronic switch is connected with main control MCU, and the other end of electronic switch is connected with thimble, and main control MCU is connected by serial bus with tested cell phone mainboard.
Between above-mentioned thimble and electronic switch, connect by winding displacement.
Above-mentioned thimble is thimble matrix.
Above-mentioned electronic switch is matrix electronic switch.
[0009]the beneficial effects of the utility model are: utilize electronic switch to replace tester to control thimble, realized the automation of cell phone mainboard keyboard test, reduced testing cost, improved accuracy and the reliability of testing efficiency and test result.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model is not limited to the following stated.
[0012]as shown in Figure 1, a kind of cell phone keyboard Auto-Test System, it comprises test fixture and Test Host, and tested cell phone mainboard is placed on test fixture, and the thimble matching with tested cell phone mainboard keyboard is housed on test fixture, and described thimble is thimble matrix; Test Host comprises electronic switch and main control MCU, described electronic switch is the electronic switch matrix of 8 х 8, the control signal input of the electronic switch matrix of 8 х 8 is connected with main control MCU, the other end of the electronic switch matrix of 8 х 8 is connected with thimble by winding displacement, and main control MCU is connected by serial bus with tested cell phone mainboard.
The course of work of the present utility model is: tested cell phone mainboard is fixed on the test fixture that thimble is housed, between tested cell phone mainboard and main control MCU, by serial bus transmission of information, makes tested palm main frame enter into key testing pattern; Meanwhile, 8 х 8 electronic switch matrixs conductings successively under the control information of main control MCU, press tested cell phone mainboard keyboard thereby control thimble, and now the built-in keyboard test subprogram of tested mainboard records successively by keypad situation; Treat that tested cell phone mainboard keyboard all tests, thimble stops pressing motion, and data are sent to main control MCU.In whole test process, if find bad button, tested main frame will send alarm signal.
