Abstract
The utility model provides an electronic testing device for a printed circuit board, which comprises a needle bed seat, an upright post provided with a guiding rail and positioned on the needle bed seat, and lifting hold-down mechanism provided with a slide block matched with the guiding rail on the upright post. The electronic testing device is characterized in that a printed circuit board needle bed with an identical structure as a tested printed circuit board is mounted on the needle bed seat through a connecting piece; probe mounting holes corresponding to the tested points on the tested printed circuit board are formed on the printed circuit board needle bed; and probes are mounted in the probe mounting holes. The utility model has the advantages of convenient needle bed manufacture and replacement, concentrated conducting wire placement and aesthetic appearance, and can realize test automation.
Description
Technical field:
The utility model is relevant with the printed circuit board electron proving installation, and is relevant with the printed circuit board electron proving installation that adopts the printed circuit board needle-bar especially.
Background technology:
Along with the development of electronic technology and printed circuit board manufacturing technology, modern electronic product is increasingly sophisticated, and the density of printed circuit board (pcb board) increases day by day, and the thing followed is the detection of printed circuit board and repairs also difficult further.For the detection that improves printed circuit board and the automaticity of maintenance, everybody has begun to carry out the printed circuit board Automatic Testing System.Through the development of two more than ten years, various printed circuit board test macros emerge in an endless stream.
At present, the development of printed circuit board automatic test technology is rapid, and the printed circuit board Online Transaction Processing is widely used in production, detection and the maintenance etc. of the printed circuit board of printed circuit board tabula rasa and various products.By and come needed frock (anchor clamps) in the test process is constantly claimed, so circuit board testing instrument (claiming the Electronic Testing frock again) arises at the historic moment.
Existing printed circuit electronic test equipment comprises the needle-bar seat, be loaded on the column of the band guide rail on the needle-bar seat, the lifting hold-down mechanism of the slide block that cooperates with guide rail of band is positioned at the needle-bar of making of insulating sheet material on the needle-bar seat, be contained in the probe on the needle-bar, the bottom of probe is with the scolding tin output carrier of burn-oning.
The needle-bar processing process is: the PCB cad data, and----numerical control CNC processing, borehole data--numerical control CNC processing--assemble, welding lead for data preparation and conversion.
Find out from above, needle-bar processing technology complexity, data-switching easily goes wrong, be not easy to take out after in use probe damages simultaneously to change and (on needle-bar, fix in order to guarantee probe, general gap or the interference fit of adopting), and wire bonds trouble, not attractive in appearance below the probe, and lead is changed inconvenient.Because a printed circuit board at a needle-bar, if printed circuit board is done some adjustment, improvement, upgrading, or is used to test another kind of printed circuit board, that can only arrive the tailor-made needle-bar of specialized factory again, and is time-consuming like this, very dumb simultaneously.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, provides a kind of needle-bar to make, change convenient, settles in the line set, and good looking appearance can be realized the printed circuit board electron proving installation of test automation.
The purpose of this utility model is achieved like this:
The utility model printed circuit board electron proving installation, comprise the needle-bar seat, be positioned at the column of the band guide rail on the needle-bar seat, the lifting hold-down mechanism of the slide block that band cooperates with guide rail on the column, it is characterized in that by web member the printed circuit board needle-bar identical with printed circuit plate structure to be measured being housed on the needle-bar seat, the probe mounting hole corresponding with tested point on the printed circuit board to be measured arranged on the printed circuit board needle-bar, on the probe mounting hole probe is housed, the location pin is housed on the printed circuit board needle-bar.Needle-bar structure and tested printed circuit board are just the same, can make simultaneously with tested printed circuit board, so needle-bar is easy to make, probe can adopt scolding tin to be welded on the needle-bar, can conveniently install or change probe, lead, can be used to test multiple printed circuit board by changing needle-bar, can on needle-bar, increase circuit and needle-bar be had to the circuit-under-test plate provide functions such as power supply, test signal with the realization test automation.
The position of relative printed circuit board needle-bar is a cavity on the above-mentioned needle-bar seat, and the output carrier is loaded in the cavity, has realized settling in the line set of proving installation, makes electronic test equipment overall appearance, generous.
During test, printed circuit board to be measured is contained on the pin of location, the lifting hold-down mechanism compresses printed circuit board (PCB) to be measured and test point is contacted with probe test.
The utility model adopts the printed circuit board needle-bar, so the whole testing device modularization.When needing little other printed circuit board of test profile variation, can directly change corresponding with it printed circuit board needle-bar.Adopt above-mentioned printed circuit board plate needle-bar design, simplified the processing technology of needle-bar greatly, no longer need the CNC needle-bar processing after the data conversion, only need just design and produce the printed circuit board needle-bar simultaneously at design printed circuit panel products, guaranteed that Design and Machining is accurate, guaranteed to realize the timely of test function, also guaranteed the low cost of proving installation.After same probe damages, so because the welding of adoptable scolding tin also can be easy to change, do not need welding lead again behind the replacing test probe, harness damage is changed also quite easily convenient, because the making of standard winding displacement is very simple, so just guaranteed that the frock maintenance is quite simple and easy.When the printed circuit panel products is done some adjustment, upgrading, also can make corresponding printed circuit board needle-bar easily, realize that model machine just reaches test function, with low cost, flexibility and reliability.Owing to adopt the printed circuit board needle-bar, needle-bar just can have been integrated more function, so just can realize the more test functions and the effect of electronic test equipment, can realize test automation simultaneously.The utility model device integral body is cleaner and tidier, elegant in appearance.
