Abstract
The invention discloses a testing device for an SVG driver board. The testing device is characterized in that the driver board is flatly placed on the testing device, and a pressing plate makes contact with the driver board; the pressing plate is connected with a test board, and test inserting pins of the test board are distributed on the pressing plate; the test board is used for uploading tested data to an upper computer so as to detect the electrical performance of the driver board conveniently and rapidly. Through the adoption of the structure, the testing device can be used for detecting all points on the driver board together, uploading data of all the points to the upper computer and storing the data of all the points in the upper computer. Accordingly, mass production of the driver boards is greatly facilitated, and the purpose that the electrical performance of the SVG driver board can be tested conveniently and rapidly is achieved.
Description
Technical field
The present invention relates to the performance test field of SVG drive plate, particularly a kind of proving installation for SVG drive plate.
Background technology
Each SVG device has 36 drive plates, normal for guaranteeing each electrical property of version that drives, and all needs every drive plate to carry out electric performance test.
Most producer adopts fixture by the input that will detect on drive plate out, compares, thereby judge that whether normal drive plate is with theoretical value.But this fixture is some point, be directly with the table on fixture, to show, and some point can only be guided on the binding post of a side of fixture and adopts multimeter to test out, and brings a lot of inconvenience to like this production in enormous quantities SVG, has also taken a large amount of time.
For the problems referred to above, a kind of novel proving installation is provided, conveniently the electrical property of SVG drive plate being tested is the problem that prior art need to solve.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of proving installation for SVG drive plate, to reach the object of conveniently electrical property of SVG drive plate being tested.
For achieving the above object, technical scheme of the present invention is, a kind of proving installation for SVG drive plate, is characterized in that: described drive plate lies on proving installation, and pressing plate contacts with drive plate; Pressing plate is connected with test board, and the test contact pin of test board is arranged on pressing plate; Test board by test to data upload to host computer, thereby conveniently the electrical property of drive plate is detected.
Described pressing plate is connected on air pump, guarantees that pressing plate contacts closely with drive plate.
The position of test contact pin of described test board and the position of the signal testing point of drive plate are consistent.
Described proving installation is provided with power interface and provides power supply for whole proving installation.
Between described check-out console and host computer, adopt the communication serial ports of RS485 to communicate.
A kind of proving installation for SVG drive plate, owing to adopting above-mentioned structure, the present invention can a little can detect together to the institute on drive plate, upload to host computer, and be kept at host computer, bring very large convenience to like this production in enormous quantities drive plate, reach the object of conveniently electrical property of SVG drive plate being tested.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation;
Fig. 1 is the structural representation of a kind of proving installation for SVG drive plate of the present invention;
Fig. 2 is the software flow pattern of a kind of proving installation for SVG drive plate of the present invention;
In Fig. 1,1, pressing plate; 2, drive plate; 3, communication serial ports; 4, air pump; 5, power interface.
Embodiment
The present invention fills one 1 li of pressing plate to measure plate, this is measured plate and all test point collections on drive plate 2 can be got up, then by 485 communication serial ports 3, upload on host computer, 2 of drive plates of every like this survey are with checking whether correctly data on host computer.To production in enormous quantities, brought very large convenience like this, saved the plenty of time, and these data directly can have been saved on host computer, need not be as also will manually data recording being got up in the past.
Specifically as shown in Figure 1, the present invention includes drive plate 2 and lie on proving installation, pressing plate 1 contacts with drive plate 2; Pressing plate 1 is connected with test board, and the test contact pin of test board is arranged on pressing plate 1; Test board by test to data upload to host computer, thereby conveniently the electrical property of drive plate 2 is detected.
As shown in Figure 2, the present invention is for SVG drive plate electric performance test, by the effect of air pump 4, needs the contact pin close contact on signaling point and the pressing plate 1 of test on drive plate 2, thereby collects fully the signal of needs.Originally by a lot of piece voltage tables, also had a lot of binding posts to form, and when surveying a plank, all needed to record the magnitude of voltage on these planks at every turn, also having is exactly to measure the signal value on these binding posts with multimeter.But as its name suggests, a SVG device has 36 drive plates, and while producing SVG in a large number, drive plate can be more, and so traditional method of testing is obviously pretty troublesome, the expensive time.
Use 485 communication serial ports 3 to be uploaded to host computer data.When after the correct placement of drive plate, host computer is opened communication port, first carries out initialization, and then host computer judges whether access means, accesses which platform equipment.Then host computer sends reading order to equipment, and the test board of fixture will return to the data that read by 485 communications protocol.Tested after data and stored away with upper organizational security, each data of measuring can be kept in a form automatically, specifically show project, the numerical value of test and the concrete time of test of test.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
