Description

Testing device and method for PCBA of smart watch

Technical Field

The invention relates to the field of testing of intelligent watches, in particular to a device and a method for testing a PCBA (printed Circuit Board Assembly) of an intelligent watch.

Background

The intelligent watch PCBA test generally needs the support of test fixture, through giving the test fixture bottom plate programming, drive screen display, button, LCD etc. realize the control and the demonstration of test fixture bottom plate to test PCBA. Because the testing bottom plate is controlled by the single chip microcomputer, the programming difficulty is large, the time is long, the modification is inconvenient, and the flexibility is poor. After the test fixture obtains the PCBA parameters, the parameters of different devices and different batches can not be flexibly set, the test fixture can not automatically judge whether the parameters pass or not, the worker needs to perform key feedback judgment, the worker needs to monitor the test progress all the time, one worker can only operate one test fixture, and the labor cost is high. Therefore, the computer program is easy to develop and maintain, the parameter threshold can be flexibly set in a mode of providing a configuration interface, whether the parameter threshold is successful or not is automatically judged, monitoring and judgment by workers are not needed, the workers only need to place the boards, the boards are sorted according to the result finally prompted by the computer, and operation of the workers is greatly simplified.

The test fixture control system generally takes a single chip microcomputer chip as a main control, and in addition, a key, an indicator light, a buzzer, a screen and the like are added to form a test control system which can be controlled, displayed and simply interacted. The singlechip generally needs to support driving Bluetooth, a serial port, an LED lamp, a key, a buzzer and a screen. The serial port is used for communication data interaction, the test fixture can read configuration from the PCBA and can also send instructions to enable the PCBA to execute test actions, and then test results are obtained. By changing the display color and the flicker frequency of the LED lamp, the running state is fed back to an operator, and a basis is provided for the judgment of the operator. The buzzer sounds or makes a jerky or differently spaced sound, providing a feedback status similar to that of an LED, giving the operator a prompt from the direction of hearing. The key is mainly used for detecting parts with parameter difference caused by batch and other reasons, and the detection of the parts needs to manually judge results. And the testing jig displays the parameters on a screen after obtaining the parameters, and a worker presses the pass/fail key distinguished by red and green according to the standard, and feeds the result back to the testing jig for the testing jig to judge the final testing result. The screen is responsible for displaying comprehensive test information, displaying test items according to a list, and indicating the test result by changing the color of the color block after each test result is obtained. The test system which takes the test fixture system as the main control can interact with the PCBA board, can give feedback to operators from the aspects of vision and hearing, and can meet the basic PCBA test requirement.

The problems of low automation degree, low efficiency and high quality control risk generally exist in some current PCBA testing methods. The automation degree is low, the labor is excessively depended on, high labor expenditure is brought, and the cost is high. Items needing manual judgment are easy to have misjudgment and misjudgment, so that the problems of high rework rate, high quality control risk and waste of working hours are very severe.
