Abstract
The invention discloses a method for automatically testing circuit boards. The method comprises the following steps of: mounting a sucker bracket on a cylinder steel strip, and producing a sucker by four air suction pipes by using vacuum air suction; sucking different sizes of PCB boards against the different air suction pipes; building an x-o-y coordinate system in space, and building a point to be tested (x, y); placing a circuit board to be tested onto the point to be tested on a test fixture by a mechanical arm; taking the board that has been tested away from the test area and put down by the mechanical arm. According to the method, the circuit boards are subjected to automatic test, manual operation is replaced by the mechanical arm, thus being more efficient and more convenient to take and put down the boards.
Description
Technical field
The present invention relates to wiring board field, particularly a kind of method of automatic test wiring board.
Background technology
Circuit board function Auto-Test System, be mainly used in functional test, by to every test event setting range, by after according to testing process, automatically test, automatic data collection, automaticdata contrast judgement, guarantee test simplification, result visualization, the mistake of thinking of having avoided personnel, has reduced test error.
In existing wiring board test, adopt professional to test, need professional to test, need long staff training, test period is long, and testing process easily runs off, and misjudgment easily occurs test result, thereby drain to next station or client, reduced testing efficiency and test accuracy.
Summary of the invention
Based on this, the technical problem to be solved in the present invention is that a kind of method of automatic test wiring board is provided.
In order to solve the problems of the technologies described above, the technical solution scheme that the present patent application provides is:
A method for automatic test wiring board, comprises the steps:
On cylinder steel bar, suction cup carrier is installed, utilizes vacuum suction, adopt 4 aspirating air pipes to make sucker;
Adopt above-mentioned different air intake duct to hold the pcb board of different sizes;
In space, set up xoy coordinate system, set up tested pilot (x, y);
By tested pilot, with mechanical arm, accurately wiring board to be tested is placed in the tested pilot of measurement jig;
By mechanical arm, get test board, leave test zone and place test board.
As further technical scheme, after the step of tested pilot that accurately wiring board to be tested is put into measurement jig with mechanical arm, also need test plate (panel) to be measured to be placed in district to be measured by equidirectional coplanar.
As further technical scheme, after testing, also need to be connected with test machine test macro automatically testing taking laying board Electrical Control system, to obtain the qualified signal of test machine or bad signal, will place by two regions.
The application is with respect to prior art, and it has following advantage and beneficial effect:
The present invention adopts automatic test wiring board, and the operation of use mechanical arm instead of manual, can be more efficient, more easily taking laying board.
Embodiment
Below by embodiment, technical scheme of the present invention is carried out to clear, complete description; obviously; described embodiment is only a part of embodiment of the present invention; rather than whole embodiment; based on embodiments of the invention; those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
In this article, relational language, such as first and second, top and bottom etc., can be used for an entity and another entity or action to distinguish, and not inevitable requirement or adopt described entity or action between this type of relation or the order of any reality.Term " comprises ", " comprising " or other any variants, be intended to contain and exclusively have, comprise that technique, method, article or the device of enumerating element not only comprise described element for one time, but also can comprise that other do not express process that list or described, method, object product or the intrinsic element of device.By " comprising ... " the element guiding, not more multiple constraint in the situation that, and is not precluded within process, method, article or the device that comprises described element and has extra similar elements.
A method for automatic test wiring board, comprises the steps:, on cylinder steel bar, suction cup carrier is installed, and utilizes vacuum suction, adopts 4 aspirating air pipes to make sucker; Adopt above-mentioned different air intake duct to hold the pcb board of different sizes; In space, set up xoy coordinate system, set up tested pilot (x, y); By tested pilot, with mechanical arm, accurately wiring board to be tested is placed in the tested pilot of measurement jig; By mechanical arm, get test board, leave test zone and place test board.
In a preferred embodiment, after the step of tested pilot that accurately wiring board to be tested is put into measurement jig with mechanical arm, also need test plate (panel) to be measured to be placed in district to be measured by equidirectional coplanar.In addition, after testing, also need to be connected with test machine test macro automatically testing taking laying board Electrical Control system, to obtain the qualified signal of test machine or bad signal, will place by two regions.This invention has realized traditional manual test machine automated job, has reduced manual operation, has improved tested productivity; Stopped the mixed problem of putting of non-defective unit defective products in manual work process.Traditional electrical measurement test-run a machine all needs operator's handwork to carry out taking laying board to test, people's one machine of need, test step needs a large amount of labours, cost of labor also constantly rises, and there is very large probability that problem board has been put into plate, cause defective products leakage to lower operation, directly eliminate Manual testing machine provided enterprise and can increase huge equipment cost, therefore develop mature technology aspect mechanical arm smart electronics on manual test basis, design robotization taking laying board device and replace manual testing's operation.
Above embodiment has only expressed preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
