Upward and downward conveying mechanism used for testing of electronic control units of automobile engine

Abstract

The invention discloses an upward and downward conveying mechanism used for testing of electronic control units of automobile engines and a test method. The upward and downward conveying mechanism comprises a main board, a left clamp, a right clamp, a middle clamp, an upper-layer pushing unit driver, a RUNIN test head, a lower-layer pushing unit, an FT test head, a rotating mechanism, an unloadingmechanism and etc. The upward and downward conveying mechanism used for testing of electronic control units of automobile engines reduces device width, saves space, has a stable and precise structure, does not manual work respectively for piece placement and reduces labor cost. According to an automobile engine electronic control unit test method disclosed by the invention, RUNIN test and FT testcan be carried out at the same time, links can be saved and time can be reduced by one time.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to an upper and lower transmission mechanism for testing an electronic control unit of an automobile engine and a testing method thereof. Background technique [0002] Before the electronic control unit of the automobile engine leaves the factory, it needs to pass the RUNIN test (simulating the continuous high-intensity operation of the machine by the user) and the FT test (the overall function test). The test time is 50 seconds. During the test, the front and rear of the electronic control unit of the automobile engine are respectively connected with different test heads. [0003] There are generally two methods for current test equipment: one is that the RUNIN test equipment is independent of the FT test equipment; the other is that the RUNIN test and the FT test are integrated, and the FT test is automatically switched after the RUNIN test is completed by changing t...

Problems solved by technology

Defects of method 1: 1. The width and depth of a single device is 600mm*150mm, and the combined area of ​​the two devices is 1200mm*150mm, which is too large; 2. The parts need to be placed manually, which increases the workload of people

The defect of method 2: the RUNIN test and the FT test cannot be carried out synchronously. The FT test can only be performed when the RUNIN test is completed. Affect work efficiency
