Double-lens double-bottom-light transverse synchronous movement system and image detector using same

Abstract

The invention provides a double-lens double-bottom-light transverse synchronous movement system. Two lens testing modules which are parallel in a transverse direction and two lens relative movement devices are arranged on a lens table. The lens table is connected with a bottom optical table through a synchronous traction device. The bottom optical table is provided with the two bottom light irradiating modules which are parallel in the transverse direction and two bottom light relative movement devices. The invention further provides an image detector in which the double-lens double-bottom-light transverse synchronous movement system. A gantry frame is provided with the double-lens double-bottom-light transverse synchronous movement system. Therefore, according to the double-lens double-bottom-light transverse synchronous movement system, two lenses and two bottom light beams can be quickly moved to positions of two to-be-tested workpieces in the transverse direction, thereby further improving testing efficiency. Furthermore the double-lens double-bottom-light transverse synchronous movement system has advantages of simple structure and low fabrication cost. Obviously, the image detector with the double-lens double-bottom-light transverse synchronous movement system has beneficial effects of high testing efficiency, simple structure and low fabrication cost.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a dual-lens dual-bottom light lateral synchronous movement system and an image detector using the system. Background technique [0002] Image detector is an inspection and measurement instrument that obtains information such as the size and appearance of the workpiece to be inspected through a lens. It has the characteristics of fast, intuitive and accurate inspection, so it is widely used in various industrial fields. In order to have a better detection effect, a bottom light is provided under the lens, so that the workpiece to be detected located between the lens and the bottom light can be better presented in the lens. [0003] The general image detector is only equipped with a single lens and a single bottom light, and can detect one workpiece at a time. Although it can also complete the detection work, the detection efficiency needs to be improved. At present, there...

Problems solved by technology

At present, there are also image detectors equipped with dual lenses and double bottom light, which can detect two workpieces at the same time, and the detection efficiency is improved. However, in order to meet the positioning requirements of two lenses and two bottom lights, the existing dual lens double bottom light The image detector is equipped with at least one set of independent lateral movement system for each lens and each bottom light, so the whole image detector has the disadvantages of high cost and complex structure.
