Description

Technical Field

[0001] The present invention relates to the technical field of light source devices, and in particular to a composite light source device. Background Art

[0002] In the production process of photovoltaic glass sheets, common defects are inevitably generated, such as bubbles, open bubbles, stones, bumps, roller scratches, etc. In the back-end production process, scratches on the upper and lower surfaces will also appear. In order to ensure the safety and performance requirements of photovoltaic glass, defect detection is required before leaving the factory to avoid greater losses.

[0003] The currently commonly used automated inspection method is to use industrial visual inspection equipment for inspection, and to achieve defect detection by flashing multiple light sources in a single station in different lighting modes to show the different characteristics of various defects. The light sources in the existing solution include low-angle transmission light sources and direct light sources. The low-angle transmission light sources are located on one side of the direct light sources. The arrangement of the above light sources causes the light sources to occupy too much space. Since most glass factories use rollers to transport glass piece by piece, this solution will increase the distance between the two rubber rollers, forming a relatively large gap in the production line. When the glass passes through two adjacent rubber rollers, the glass head and glass tail will have more obvious jitter and glass slippage, resulting in the bending and deformation of the glass head and glass tail in the image captured by the visual inspection equipment, which has a huge impact on defect detection and size measurement. Summary of the invention

[0066] The currently commonly used automated inspection method for photovoltaic glass is to use industrial visual inspection equipment for inspection, and defect detection is achieved by flashing multiple light sources in a single station in different lighting modes to show the different characteristics of various defects. The light sources in the existing solution include low-angle transmission light sources and direct light sources. The low-angle transmission light sources are located on one side of the direct light sources. The arrangement of the above light sources causes the light sources to occupy too much space. Since most glass factories use rollers to transport glass piece by piece, this solution will increase the distance between the two rubber rollers, forming a relatively large gap in the production line. When the glass passes through two adjacent rubber rollers, the glass head and glass tail will have more obvious shaking and glass slippage, resulting in the bending and deformation of the glass head and glass tail in the image captured by the visual inspection equipment, which has a huge impact on defect detection and size measurement.
