Abstract

The invention discloses a system for automatically diagnosing a fault of a circuit board. The system comprises a testing probe, a signal excitation device, a signal testing device, a central control machine and a robot movement mechanism, wherein the central control machine controls the signal excitation device; the signal excitation device is connected with a signal excitation end of a circuit board; the testing probe acquires data of a tested point of the circuit board to be transmitted to the signal testing device; the signal testing device processes the data and transmits the data to the central control machine; the central control machine controls the robot movement mechanism; the robot movement mechanism is used for controlling the testing probe to move; and the testing probe is used for testing the fault of the circuit board. The robot movement mechanism is controlled to drive the testing probe to move to a target testing point by the central control machine, so that fault diagnosis of the circuit board is fully automatically tested, manual operation is replaced by the robot movement mechanism, and manual labor is saved; and moreover, the fault of the circuit board can be accurately tested, and the system is convenient to use.

Description

technical field [0001] The invention relates to a circuit board fault diagnosis device, in particular to a system and a diagnosis method for automatically performing circuit board fault diagnosis through a robot movement mechanism. Background technique [0002] At present, more and more electronic products are used, and when an electronic product fails, it is often necessary to perform fault diagnosis on the circuit board therein. For example, the Chinese patent application document with the publication number "CN 101806857A" discloses an online circuit board fault diagnosis instrument, which includes a host computer for online signal processing and fault diagnosis, and is used to provide the required signals for the circuit board under test and The lower computer that uploads the test information, the upper computer and the lower computer are connected and communicated by serial bus. The upper computer adopts a portable notebook computer with built-in fault diagnosis exper...
