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

[0069] 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.

[0070] In order to solve the above problems, Figure 1-Figure 5 As shown, this embodiment provides a composite light source device, including a supporting and fixing component 1 and a light source component 3, wherein a receiving cavity is provided in the supporting and fixing component 1; the light source component 3 is provided in the receiving cavity, and the light source component 3 is supported and fixed on the supporting and fixing component 1; the light source component 3 includes a straight light source component 31 and a low-transmittance light source component 32, and the low-transmittance light source component 32 is obliquely provided on one side of the straight light source component 31, and the straight light source component 31 and the low-transmittance light source component 32 are both provided toward the same side of the supporting and fixing component 1, and the light of the straight light source component 31 and the low-transmittance light source component 32 is emitted from the same side of the supporting and fixing component 1. The composite light source device arranges the straight light source component 31 and the low-transmittance light source component 32 in the same device, thereby reducing the overall occupied space, reducing the defect detection error, and improving the defect detection accuracy.

[0071] Preferably, the low-transmittance light source component 32 is tilted to form an angle α with the straight light source component 31, and the value range of α is 20° to 50°. This setting can effectively detect glass scratches and bubbles. α can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, etc.

The fixing parts pass through the corresponding first fixing holes and the second fixing holes to firmly fix the first heat dissipation profile 111 and the second heat dissipation profile 112 on the base plate 121. The side plate 122 is arranged on the side of the first heat dissipation profile 111 away from the second heat dissipation profile 112; the transparent protective cover plate 123 is arranged on the top of the side plate 122 and the heat dissipation support assembly 11, and the transparent protective cover plate 123 and the side plate 122 are connected by the support structure 124.

The above-mentioned cover plate assembly 12 can cooperate with the heat dissipation support assembly 11 to enclose a receiving cavity for receiving the light source assembly 3, so as to facilitate the receiving and installation of the light source assembly 3.

[0075] Furthermore, if Figure 5 and Figure 7 As shown, the cover plate assembly 12 further includes a support positioning member 125, and the support positioning members 125 are provided at both ends of the heat dissipation support assembly 11.
