Description
Technical Field
The invention relates to the field of electronic test and measurement, in particular to an all-dimensional automatic mobile test system for a test fixture.
Background
In normal production, the circuit board needs to be functionally tested to ensure that various performances of the circuit board meet customer requirements. In the testing process, the testing module needs to be moved up and down, the light reflecting module is moved left and right, and the circuit board is tested. These operations all require manual operations, including lifting the test module, pressing the test module down, moving the reflective module to the left, moving the reflective module to the right, and so on. These operations present some potential testing risks. These risks are not completely avoided during manual testing.
There is also a risk in reading the test results, for example: staff misread the voltage value of the test result, and the equipment for measuring the voltage is abnormal, resulting in reading deviation, which can cause adverse effects on the quality of the product and the feedback at the client.

A clamp submodule: the test circuit board is moved up and down to meet the height requirement of the test, so that the voltage meets the test requirement; the fixture light reflection submodule: the submodules made of different light-reflecting materials are pneumatically moved left and right, so that different requirements of test voltage are met, and the voltage meets the test requirements.
The raspberry group computer is electrically connected with the expansion electronic circuit board through a USB interface, the expansion electronic circuit board is electrically connected with the drive control device, and the drive control device is connected with the raspberry group computer through the USB interface.
And sending an instruction through the raspberry dispatching computer, receiving the instruction of the raspberry dispatching computer by the expansion electronic circuit board, controlling the drive control device to test, feeding a test result back to the test software, and displaying pass/fail in the software. Therefore, the aim of the user is achieved, the test is automatic, the multi-step manual operation of personnel is reduced, and the test is automatically completed.
When the test tool is used, the board is placed into the clamp and then starts to be tested, and the raspberry sending computer sends a command through the USB interface; after receiving the command, the clamp expansion board transmits a signal to the drive control device; the pneumatic module controls the work of the clamp submodule and the clamp light-reflecting submodule; feeding back the test result to a raspberry host computer through a USB interface; the raspberry host computer displays that the result passes or fails.
The omnibearing automatic moving test system for the test fixture has the beneficial effects that:
a. the scheme automatically completes the test, and the test is converted into the automatic test by full manual operation, so that the working efficiency is improved.
c. The automatic and standardized test avoids errors in setting and judgment in the test process, and improves the test accuracy.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
