Problems solved by technology
However, once there are a large number of machines, whether it is in the stage of installation setting or in the stage of machine maintenance in the future, it is not only time-consuming to manually set and adjust one by one, but it is also impossible to make the detection standards of each machine uniform. Such a shortcoming It often causes the products that pass the test to be unable to maintain stable product quality

Embodiment Construction
[0024] For fully understanding purpose of the present invention, feature and technical effect, hereby by following specific embodiment, in conjunction with accompanying drawing, the present invention is described in detail, as follows:
[0025] First please refer to figure 1 , which is a schematic diagram of an optical detection machine in an embodiment of the present invention. The optical inspection machine for various circuit board inspections includes: at least one light source device ( figure 1 Shown are the first light source device 111 and the second light source device 112 ), the image capturing device 120 , the computing host 130 and the carrying platform 140 . The carrying platform 140 is used to place the target object 200 to be measured, and the target object 200 to be measured generates light such as reflected light or scattered light correspondingly through the light irradiation of the first light source device 111 and the second light source device 112 And the...

The invention discloses a method for setting for sharing setting parameters between optical inspection apparatuses, which is used to transfer a reference light source output setting value of a reference optical inspection machine to another optical inspection machine correspondingly. The method comprises the steps of obtaining a reference gray value, obtaining a test gray value, adjusting a light source apparatus and setting the light source apparatus. By taking a reference sheet as the reference target of multiple machines, the actual irradiation condition of each machine can be uniformed automatically according to the standard. Therefore, the inspection stand of all optical inspection machines are about the same, and the products to be inspected have the uniform quality standard.
Description
technical field [0001] The invention relates to a setting method of optical detection machines, in particular to a setting method of shared setting parameters among optical detection machines. Background technique [0002] Automated optical inspection (AOI) plays a pivotal role in the inspection of flexible or rigid circuit boards. For example, in the manufacturing process of liquid crystal display, semiconductor integrated circuit chips and related circuits, precise automatic optical inspection is required. [0003] The automatic optical inspection is carried out by the optical inspection machine. During the inspection process, the light is irradiated onto the circuit board, and then the image of the circuit board is captured by the imaging device to judge the defect. Therefore, the optical inspection machine The quality of the light source provided by the lighting device on the stage has considerable influence on the inspection. Once the quality of the light source is not...
