Light source device, substrate illumination system and method

Abstract

According to the light source device and the substrate illumination system and method, the driving assembly drives the illumination assembly to move on the arc guide rail, so that the illumination light source does circumferential rotation with the observation point as the circle center, and illumination light emitted by the illumination light source changes at the reflection point of the reflection panel; however, after being reflected by the reflection panel, the light reaches the position of the back surface of the substrate and illuminates the observation point of the substrate. The device is simple and reliable in structure, and the position of the illumination assembly does not need to be repeatedly debugged while a reflection blind area on the reflection plate is avoided, so that illumination light can be always reflected to the back surface of an observation point of the substrate, and illumination is provided for the observation point of the substrate.

Description

Technical Field

[0001] This invention belongs to the field of testing equipment, specifically relating to a light source device, a substrate illumination system, and a method. Background Technology

[0002] Typically, the illumination source is fixed directly to the equipment and cannot be moved. The illumination light emitted from the source passes through the substrate (product), the transparent glass platform, is reflected by the reflective panel, and then passes through the transparent glass platform again to reach the back of the substrate. Sufficient brightness allows the observation lens to clearly see the pattern on the substrate below the observation path. However, to handle the substrate, the equipment uses a lifting column to lift it, facilitating the robotic arm's handling. This creates lifting holes in the reflective panel. When the reflection point of the illumination light falls within the area of ​​these lifting holes, the illumination source cannot effectively reflect the light.

[0003] Patent CN202916546U provides a detection device for detecting a display substrate, comprising: a base; a liftable support structure disposed within the base; and a reflective surface of the portion of the support structure that supports the display substrate.

[0004] However, in patent CN202916546U, when the light beam is irradiated on the surface of the support structure, the path of the reflected light beam will also change, and the point where the light beam is reflected to the display substrate will also change. It is necessary to repeatedly adjust the incident angle of the incident light so that the outgoing light irradiates the back of the observation point of the display substrate. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of this invention is to provide a light source device, a substrate lighting system, and a method.

[0006] According to the present invention, a light source device is provided for providing illumination to an observation point by avoiding the illumination blind zone on a reflective panel, comprising: an arc guide rail, an illumination component, and a driving component;

[0007] The lighting component is movably mounted on the arc-shaped guide rail for projecting light onto the reflective panel;

[0008] The drive component is mounted on the lighting component and is used to drive the lighting component to move on the arc guide rail;

[0009] When the lighting component moves on the arc guide rail, the light emitting end of the lighting component moves in a circle around the observation point.

[0010] Preferably, the lighting assembly includes a lighting source and a lighting fixture. The lighting fixture is mounted on the arc guide rail, and the lighting source is mounted on one end of the lighting fixture. When the lighting fixture moves on the arc guide rail, the lighting source moves in a circle around the observation point.

[0011] Preferably, the drive component is an electric cylinder or a pneumatic cylinder.

[0012] The present invention also provides a substrate lighting system, comprising: a light source device and a reflective component;

[0013] The light source device is any one of the light source devices described above;

[0014] The reflective component is used to place the substrate and reflect the light provided by the light source device to the back of the observation point on the substrate.

[0015] Preferably, the reflective assembly includes a reflective panel and a transparent glass platform;

[0016] The transparent glass platform is positioned above the reflective panel for placing the substrate; the reflective panel is used to reflect light from the light source device, and the reflected light passes through the transparent glass platform to the back of the observation point of the substrate.

[0017] Preferably, the reflective panel and the transparent glass platform are provided with lifting holes, and a lifting column is provided in the lifting holes. The lifting column passes through the lifting holes and can lift the substrate.

[0018] Preferably, the substrate illumination system further includes an observation lens, which is positioned directly above the observation point.

[0019] The present invention also provides a substrate illumination method, based on the substrate illumination device described in any one of the above, comprising:

[0020] The substrate is placed on the reflective assembly. The light source provides light to the reflective assembly, which passes through the substrate and illuminates the reflective assembly. The reflective assembly reflects the light to the back of the observation point on the substrate, thus illuminating the observation point.

[0021] When light shines on the reflection blind zone of the reflective component, the driving component drives the lighting component to move on the arc guide rail. The light emitting end of the lighting component moves in a circle around the observation point. The illumination point of the light on the reflective component changes to avoid the reflection blind zone. The reflective component reflects the light to the back of the observation point on the substrate, and the observation point on the substrate is illuminated.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The driving component moves the lighting component along the arc-shaped guide rail, causing the lighting source to rotate in a circle around the observation point. This changes the reflection point of the lighting light emitted by the light source on the reflective panel, but the position of the light reaching the back of the substrate after reflection remains unchanged, thus illuminating the observation point on the substrate. This device has a simple and reliable structure. While avoiding the reflection blind zone on the reflective panel, it eliminates the need for repeated adjustments to the position of the lighting component, ensuring that the lighting light is always reflected to the back of the substrate observation point, providing illumination.

[0036] like Figure 1 as well as Figure 2 As shown, this embodiment provides a light source device for providing illumination to the observation point 11 by avoiding the illumination blind zone on the reflective panel 6, including: an arc guide rail 1, an illumination component and a driving component 4;

[0037] The lighting component is movably mounted on the arc guide rail 1 for emitting light onto the reflective panel 6;

[0038] The drive component 4 is mounted on the lighting component and is used to drive the lighting component to move on the arc guide rail 1;

[0039] When the lighting component moves on the arc guide rail 1, the light emitting end of the lighting component moves in a circle around the observation point 11.

[0040] The lighting assembly includes a lighting source 2 and a light source clamp 3. The light source clamp 3 is mounted on the arc guide rail 1, and the lighting source 2 is mounted on one end of the light source clamp 3. When the light source clamp 3 moves on the arc guide rail 1, the lighting source 2 moves in a circle around the observation point 11.

[0041] The drive component 4 is an electric cylinder or a pneumatic cylinder.

[0042] This embodiment also provides a substrate lighting system, including: a light source device and a reflective component;

[0043] The light source device is the light source device described above;

[0044] The reflective component is used to place the substrate 8 and reflect the light provided by the light source device to the back of the observation point 11 of the substrate 8.

[0045] The reflective assembly includes a reflective panel 6 and a transparent glass platform 5;

[0046] The transparent glass platform 5 is disposed above the reflective panel 6 and is used to place the substrate 8; the reflective panel 6 is used to reflect light from the light source device, and the reflected light passes through the transparent glass platform 5 to the back of the observation point 11 of the substrate 8.

[0047] The reflective panel 6 and the transparent glass platform 5 are provided with lifting holes 13, and lifting columns 9 are provided in the lifting holes 13. The lifting columns 9 can lift the substrate 8 by passing through the lifting holes 13.

[0048] The substrate illumination system also includes an observation lens 7, which is positioned directly above the observation point 11.

[0049] This embodiment also provides a substrate lighting method, based on the substrate lighting device described above, including:

[0050] The substrate 8 is placed on the reflective assembly. The light source device provides light to the reflective assembly. The light passes through the substrate 8 and shines on the reflective assembly. The reflective assembly reflects the light to the back of the observation point 11 on the substrate 8, and the observation point 11 on the substrate 8 is illuminated.

[0051] When light shines on the reflection blind zone of the reflective component, the driving component 4 drives the lighting component to move on the arc guide rail 1. The light emitting end of the lighting component moves around the observation point 11 in a circle. The illumination point of the light on the reflective component changes, avoiding the reflection blind zone. The reflective component reflects the light to the back of the observation point on the substrate 8, and the observation point on the substrate 11 is illuminated.

[0052] Example 1

[0053] The substrate lighting system of this embodiment 1 is applicable to the inspection and repair equipment of the display panel, i.e., substrate 8.

[0054] The lighting source 2, installed on the arc guide rail 1, is driven by the drive component 4 to make the lighting source 2 move in a circle around the observation point 11.

[0055] The illumination light 10 emitted by the illumination source 2 shines on the reflective panel 6 to form a reflection point, so that the reflection point avoids the reflection blind zone, while the illumination light 10 can still shine on the observed area after being reflected by the reflective panel 6.

[0056] The illumination light 10 emitted by the illumination source 2 passes through the substrate 8 and the transparent glass platform 5 in sequence, and shines on the reflective panel 6. The reflective panel 6 reflects the illumination light 10. After being reflected by the reflective panel 6, the illumination light 10 passes through the transparent glass platform 5 and reaches the back of the substrate 8.

[0057] Sufficient brightness allows the observation lens 7 to clearly identify the pattern on the substrate 8 below the observation route 12.

[0058] However, in order to facilitate the picking and placing of the substrate 8, the device will be provided with lifting holes 13 and lifting columns 9 on the transparent glass platform 5 and the reflective panel 6. The lifting columns 9 pass through the lifting holes 13 to lift the substrate 8, thereby facilitating the picking and placing of the substrate 8 by the robotic arm.

[0059] When the reflection point of the illumination light 10 is in the area of ​​the lifting hole 13, the illumination light 10 cannot be effectively reflected on the reflective panel 6.

[0060] To avoid the reflection blind spot of the lifting hole 13, the drive assembly 4 drives the light source fixture 3 to slide along the arc guide rail 1 and then position it at... Figure 2 The rotating illumination assembly 14 causes the light source fixture 3 to drive the illumination source 2 to rotate in a circle around the observation point 11. This causes the reflection point of the illumination light 10 emitted by the illumination source 2 to change on the reflective panel 6, but the observation point on the back of the substrate 8 after reflection on the reflective panel 6 remains unchanged. That is, the illumination light 10 can still illuminate the observed area while avoiding the reflection blind zone of the lifting hole 13.
