The test fixture of automatic function
The utility model relates to a kind of test fixture of automatic function.
Existing when not having the situation of this test platform, different circuit board under test will be made special-purpose functional test platform test, perhaps adopt general platform test, but the very important person is for judging the circuit board under test model of this test, and parameters such as manual configuration hardware device and test channel, production test efficient is low, occurs the manual operation mistake easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of test fixture of automatic function is provided.
The purpose of this utility model is achieved through the following technical solutions:
The test fixture of automatic function, it is characterized in that: comprise base, the side of described base is provided with slide rail, described slide rail is provided with the product placement platform, described product placement platform is connected with air cylinder driven, described product placement platform is provided with the product clamper of indicating circuit feature by electronic hardware, and link to each other with the interface of middle control rack, described product placement platform on the distance that described slide rail is advanced with base on product to be tested contact-making switch in place touch mutually, be provided with pick-up unit by support on the described base, described pick-up unit links to each other with middle control rack.
Further, the test fixture of above-mentioned automatic function, wherein, middle control rack is made up of the circuit board with path selective power that multiple universal measurement instrument, integrated circuit board and a cover are integrated with many group relaies.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
The utility model is used for the intelligent power system of hybrid vehicle, by indicating the product clamper of circuit feature on the product placement platform, cooperatively interact with pick-up unit, simultaneously by middle control rack it is being assisted to finish automatic detection, this device has been realized the compatible a plurality of different machines of a testing apparatus, with artificial calling program, switching hardware corridor contradiction between the two, the effective testing efficiency that improves and reduced error probability, reduced the probability of test operation mistake, reduced cost.Simultaneously product clamper has unique circuit feature by what electronic hardware was indicated, guarantees that the product and the product clamper that detect are complementary, the quickening detection speed.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: organigram of the present utility model.
As shown in Figure 1, the test fixture of automatic function, comprise base 1, the side of base 1 is provided with slide rail 5, slide rail 5 is provided with product placement platform 3, product placement platform 3 drives with cylinder 2 and is connected, product placement platform 3 is provided with the product clamper 4 of indicating circuit feature by electronic hardware, and link to each other with the interface of middle control rack 9, product placement platform 3 on the distance that described slide rail 5 is advanced with base 1 on product to be tested contact-making switch 6 in place touch mutually, be provided with pick-up unit 8 by support 7 on the base 1, pick-up unit 8 links to each other with middle control rack 9.
Wherein, for different circuit board under test, have unique and its matched products anchor clamps 4, and in different product clampers 4 and the interface that middle control rack 9 is connected corresponding mistake proofing pin position is arranged, guarantee that product clamper 4 and middle control rack 9 are complementary.
Middle control rack 9 is made up of the circuit board with path selective power that multiple universal measurement instrument, integrated circuit board and a cover are integrated with many group relaies.Test procedure can be realized the selection of different test accesss by the folding of pilot relay, simultaneously, by the folding of relay, test signal is switched on the different measurement instrument and integrated circuit board, realizes different content measurements.
Wherein, testing software in the middle control rack 9, can be by the circuit feature of monitoring product anchor clamps 4, come the type of the product clamper 4 of intelligent decision test, call corresponding test procedure, and can be according to circuit board under test signal in place, control rack 9 begins to test accordingly in controlling, in test process, the folding of automatic control relay selects suitable test access and test instrumentation and integrated circuit board to carry out automatic test.
Product clamper 4 has unique circuit feature by what electronic hardware was indicated, be connected by the interface with middle control rack 9 again, this circuit feature is passed to the control software of middle control rack 9, control software is identified which kind of product clamper 4 of current use by this, and provides information at software interface.Simultaneously, also has contact-making switch 6 on the product clamper 4, when circuit board under test in place, product placement platform 3 contacts and presses down contact-making switch 6 and makes it closed, give a circuit board under test signal in place in the control software thus, show to begin to test, prevent at circuit board under test when being in place, middle control rack 9 applies test voltage for pick-up unit 8, causes the damage of equipment and circuit board.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
