Abstract

The invention discloses a flying probe test machine light source system. The system comprises a vision module, a light source adjustment module, a light source controller and a light source assembly, wherein the vision module is connected with the light source controller through the light source adjustment module, and the light source controller is also connected with a light source on the light source assembly. Adjustment of light source on-off degrees in multiple directions can be carried out, light distribution of a pad on a flying probe test machine PCB to be tested is enabled to be more uniform, image identification is facilitated, the imaging quality is improved, and the test precision of the flying probe test machine is improved. At the same time, automatic light source adjustment helps to obtain better imaging quality, manual participation is unnecessary, the manual adjustment mode is quite simple, and the operation convenience is greatly improved. Besides, the light source system is relatively simple in structure and reliable in work, decreases the manufacturing cost of the light source system and also reduces the development time of the light source system.

Description

technical field

[0001] The present invention relates to the technical field of flying probe testing machine vision, and more specifically relates to a flying probe testing machine light source system and a control method thereof. Background technique

[0002] The flying probe testing machine obtains and calculates the relevant position of the PCB solder joint through the machine vision system, and installs a motor-driven probe on the X-Y axis that can move independently and quickly, using the controllable movement of the probe in the Z direction and fixing it on the A device that makes contact with the solder joints of a printed circuit board (PCB) on a machine and makes electrical measurements. The vision system is the eyes of the flying probe testing machine. The test position of the pad measuring point needs to be positioned and calculated by the vision system before it can guide the motion control system to perform related actions. The recognition accuracy of the vision ...
