Problems solved by technology
The throughput of the existing test system is low, which limits the improvement of production efficiency and cannot keep up with the needs of throughput. In addition, at least two sets of software and hardware test systems need to be invested in scattered test system stations, which is costly. Moreover, this The method needs to occupy a larger production line space and requires more testers

The invention relates to a composite parallel test system and a method thereof. The composite parallel test system comprises the components of a plurality of to-be-tested products which are parallelly arranged in a horizontal direction; a parallel motion mechanism which is used for making the plurality of to-be-tested products to reciprocate along the horizontal direction; a master control module which can simultaneously test the functional indexes of the plurality of to-be-tested products; and an optical test module which is used for testing the appearance indexes of the to-be-tested product. According to the composite parallel test system and the method thereof, a product appearance test function is integrated on a function test system; a composite parallel test method in which a synchronous parallel test technique and an asynchronous parallel test technique coexist is adopted; a shared resource module and resource modules which are independent from one another coexist in hardware; and the system resource can be sufficiently utilized, thereby realizing simultaneous one-time testing for a plurality of testing contents of the plurality of to-be-tested products by one test platform, shortening test time and improving testing stability.
Description
technical field [0001] The invention relates to the related technical field of automotive electronic product testing, in particular to a composite parallel testing system and method. Background technique [0002] With the rapid development of electronic technology, the technical content of automotive electronic products is increasing day by day, which makes its test content and test items continue to expand. At the same time, customers have increasingly strict requirements on product quality, not only requiring product functions and performance to meet design requirements, The appearance requirements of screen printing, lighting and color on the product surface are also very strict. The existing traditional automatic test system adopts the method of distributed test and sequential test in each test system, which requires at least two completely independent test systems: the appearance optical test system and the functional test system. At the same time, one test system stati...
