Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention includes:
a universal PCBA test platform based on raspberry group, it includes: the testing machine comprises a testing machine body and a product fixing and identifying unit.
The raspberry group is connected with the database equipment, the OLED display screen, the USB-to-serial port module, the TF card, the tester body, the universal meter and the DIO card (Digital Input and Output card), and the tester body is connected with the universal meter. The database comprises a usable entity data storage device and can also adopt a cloud server.
The raspberry pie is a microcomputer with very good performance and low price, can replace a computer in a test system, runs a Linux-based system, and can well manage user rights. Sensitive files such as test data can only be accessed, downloaded or deleted by a particular person. System and test scripts, etc. may be stored on the TF card.
The camera module is used for shooting a one-dimensional code or a two-dimensional code picture of the PCBA board, and the picture is analyzed into a bar code through a professional algorithm. The test platform can be connected with a database of a quality management system, before product testing, the test platform needs to interact with the database to check whether the product meets the requirement of testing at the test station, if so, the product can be tested, and after the test is finished, the data are uploaded to the database in real time.
The test state indicator lamp is used for indicating the test state of the board, and is convenient for an operator to judge.
The OLED display screen is mainly convenient for production line engineers or technicians to judge the state of the test system, whether the test system is initialized successfully or not can be displayed on the display screen, and some main states in the test process can also be displayed on the display screen.
The power module contains an AC/DC universal module and a DC/DC power supply to a product or test system independent module.
The universal meter is generally communicated through a USB port, a serial port or a GPIB port, and the raspberry can be conveniently communicated with the instruments after being provided with a proper driver, so that the expansibility of the universal test system is realized.
The test script is written by python, which is very convenient for system debugging.
The fixed recognition unit of product is including the detection seat that is used for placing the product, camera module, mount, the briquetting that is used for fixed product that is used for acquireing and discerning bar code on the product, detect the seat set up in detect on the quick-witted body, the mount set up in detect the top of seat, the briquetting is in the up-and-down motion on the mount.
