Automatic PCB FCT testing machine and testing method thereof

Abstract

The invention discloses an automatic PCB FCT testing machine comprising a rack. The rack includes a testing bench and a mechanical mechanism. The mechanical mechanism is provided with a console and an operation cavity, wherein the console and the operation cavity are arranged above the testing bench. The operation cavity is provided with a left testing tool and a right testing tool. The testing tools include upper die press-down mechanisms, lower die sliding table mechanisms, and cylinder mechanisms. The upper die press-down mechanisms that are connected with the upper end of the rack and are provided with tool upper dies are used for pressing a to-be-tested PCB to be in contact with the tool upper dies and to be connected with the internal testing circuit of the testing machine electrically. The lower die sliding table mechanisms that are arranged above the testing bench and can slide internally and externally include tool lower dies and are used for pressing the to-be-tested PCB to be in contact with the tool lower dies and to be engaged with the tool upper dies. The cylinder mechanisms that are connected with the upper die press-down mechanisms and the lower die sliding table mechanisms are used for realizing lifting of the upper die press-down mechanisms and external and internal sliding of the lower die sliding table mechanisms. Therefore, the testing efficiency and precision of the PCB can be improved; the procedures and method can be simplified; and the operation cost can be substantially reduced.

Description

Technical field [0001] The invention belongs to the technical field of printed board testing, and specifically relates to an automated PCB board FCT testing machine and a testing system thereof. Background technique [0002] PCB (PrintedCircuitBoard) is a printed circuit board, abbreviated as printed board, and it is one of the important parts of the electronics industry. Almost every kind of electronic equipment, from electronic watches, calculators, to computers, communication electronic equipment, military weapon systems, as long as there are electronic components such as integrated electrical appliances, printed boards must be used for electrical interconnection between them . At present, a single PCB board often includes multiple monoliths (units). These monoliths have the same structure and pattern, so that they can be divided into multiple monoliths for use after the PCB board is manufactured and tested, so as to achieve large-scale production . [0003] Before assembling...

AI Technical Summary

Problems solved by technology

The traditional circuit board test is manual insertion test or tool manual press test, the test efficiency is low, and the labor intensity of the operator is high

The automation degree of the current FCT test method has been improved to a certain extent, but it still cannot meet the operation requirements of the assembly line, and manual auxiliary operations such as product positioning are still required. Especially when the product specifications are different, the operation process is more complicated, and the degree of automation needs to be further improved.
