Abstract

The invention relates to a large-format high-speed high-precision automatic optical detector, belongs to the field of automatic optical detection, and solves the problem that the detection precision tends to be influenced by different errors when a mobile small-view-field lens is moved in a present automatic optical detector. The detector comprises a support platform, damping supports, a translation guide rail pair, a workbench on the translation guide rail pair, a transmission illumination light source, a precise driver, a control system, a grating ruler, a lens support, a reflection illumination light source, a reflector, a precise focusing platform, a large-view-field high-precision lens and a splicing detector focal plane assembly. The imaging view field of the large-view-field high-precision lens is greater than 750mm, an imaging focal plane is composed of a triangularly spliced detector array, and part or all spliced detectors are controlled to work in different frame frequencies to match the movement speeds of different workpieces. The large-view-field high-precision lens is combined with the multi-detector spliced focal plane, the problem that a single lens cannot realize large-view-field imaging but multiple lenses are inconsistent in imaging is overcome, and the detection precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automatic optical detection, in particular to a large-format, high-speed and high-precision automatic optical detection equipment. Background technique [0002] With the development of industrial technology, especially the changes in the needs of industry 2025, the requirements for detection accuracy, detection speed and detection size in the field of automatic optical inspection (AIO) such as industrial circuit boards, solder paste, and stencils continue to increase. The requirements for automatic optical inspection equipment are getting higher and higher, so how to improve the indicators of inspection equipment to adapt to the development of industrial technology is very urgent. [0003] At present, the automatic optical inspection (AIO) equipment adopts small field of view optical lens, which is installed on the X / Y translation platform to image the local area of ​​the workpiece (circuit board, solder ...
